3	Mainly stuff to improve handling of TYPE_CODE_REF values.
4	* valops.c (value_addr):  If taking the addres of a
5	TYPE_CODE_REF, just cast the object to the corresponding
6	TYPE_CODE_PTR.  This yields correct C++ semantics, and
7	preserves the location information, which has the nice effect
8	that &(&R) given the location containing R.
9	* values.c (value_copy):  Make non-static (used by value_addr).
10	* eval.c (evaluate_subexp_for_address):  Use the default
11	scheme (with value_addr) for a variable if it has TYPE_CODE_REF.
12	* valops.c (value_addr), eval.c (evaluate_subexp_for_address,
13	evaluate_subexp_with_coercion):  Factor out some common
14	expressions into variables, for easier reading.
15	* findvar.c (locate_var_value):  Remove code to handle
16	TYPE_CODE_REF - it should no longer be needed.
17	* valops.c (value_assign):  Do a COERCE_REF on the
18	destination operand, for correct C++ semantics.
19	* valarith.c (value_x_binop):  Ditto:  De-reference C++
20	references in the arguments.
21	* valops.c:  ANSI-fy: bcopy->memcpy, bzero->memset.
22
23Sat Dec 28 11:30:26 1991  Per Bothner  (bothner at cygnus.com)
24
25	* dwarfread.c, coffread.c:  Use INIT_CPLUS_SPECIFIC.
26	* symtab.c (gdb_mangle_name):  Recognize and handle
27	constructors specially.
28	* symtab.c (check_stub_method):  Test for failure from
29	cplus-demangle by calling error() instead of seg-faulting ...
30
31Fri Dec 27 22:21:30 1991  Fred Fish  (fnf at cygnus.com)
32
33	* defs.h:  Add definition of null_cleanup()
34
35	* procfs.c:  Many small changes to add base support for a new
36	"info proc" command (currently only printing of the address
37	space mapping is implemented) and allow iteration over the
38	address space mapping, calling an arbitrary function for each
39	mapping (used for shared library support).
40
41	* solib.c:  Change all ifdefs that checked for "sun" to check
42	for "!SVR4_SHARED_LIBS" instead.  Rewrite lookup_base() to
43	handle locating the debug base address even when not currently
44	stopped at the dynamic linker entry point.
45
46	* utils.c:  Add null_cleanup() as a known function that does
47	nothing to serve as a base for possibly long cleanup chains
48	with no specific "first cleanup" to serve as an anchor.
49
50	* xm-sysv4.h:  Add define of SVR4_SHARED_LIBS
51
52Fri Dec 27 10:11:33 1991  Per Bothner  (bothner at cygnus.com)
53
54	* arm-opcode.h, m88k-opcode.h, pn-opcode.h, np1-opcode.h,
55	pyr-opcode.h, tahoe-opcode, vax-opcode.h:  Removed -
56	these are all essentially the same as the versions
57	in ../include/opcode.  The remaining *-opcode.h here
58	are not quite so obviously the same, and need study.
59	* arm-pinsn.c, gould-pinsn.c, m88k-pinsn.c, pyr-pinsn.c,
60	tahoe-pinsn.c, vax-pinsn.c:  Change so these include
61	opcode/FOO.h (actually ../include/opcode/FOO.h)
62	instead of the recenntly departed opcode-FOO.h files.
63	* sparc-pinsn.c:  Now that we're using the much tighter
64	opcode table in ../include/opcode/sparc.h, we shouldn't
65	need to sort the opcodes before dis-assembly.
66
67	* symtab.h, symmisc.c:  Make cplus_struct_default be const.
68	* symtab.h, buildsym.c:  Add and use INIT_CPLUS_SPECIFIC macro.
69	* symmisc.c:  Remove unused 'nfields' variable.
70	* buildsym.h:  Add extern decl of unknown_symtype_complaint,
71	since it used used by partial-stab.h (included two places).
72	* partial-stab.h:  Re-arrange DBXREAD_ONLY #ifdefs so that
73	we should never hit the default case (until new stab codes
74	are added).  Hence, we can leave the complaint in the
75	default case in even when DBXREAD_ONLY is off.
76	* partial_stab.h: Recognize a pair of N_SO stabs (one for the
77	directory, one for the filename proper) without peeking ahead.
78	* dbxread.c, mipsread.c: Because of previous change, don't need
79	ugly CHECK_SECOND_N_SO macro.
80	* buildsym.h, dbxread.c, mipsread.c:  Make next_symbol_text a
81	macro that invokes a function pointer in next_symbol_text_func.
82	* mipsread.c:  Added comments various places to
83	explain what is going on.
84	* mipsread.c (parse_symbol):  Support the new (SGI-specific?)
85	symbol types stStruct, stUnion, and stEnum.
86	Also, some fixes in the code for dealing with tags.
87	* mipsread.c:  Change handling of startup_file_start and _end
88	- now just use the textlow and texhigh of a psymtab
89	to check if we've found the startup-file.
90	* mipsread.c:  Replace s_idx by global cur_sdx in many places.
91	This is so mips_next_symbol_text can get at it.
92
93Thu Dec 26 19:52:01 1991  Fred Fish  (fnf at cygnus.com)
94
95	* dbxread.c, symmisc.c:  Move add_psymbol_to_plist() from
96	dbxread.c to symmisc and change name to add_psymbol_to_list.
97	Ditto for add_psymbol_addr_to_plist().  Also expand their
98	body to not use ADD_PSYMBOL_VT_TO_LIST.
99
100	* dwarfread.c:  Remove add_psymbol_to_list() and convert usages
101	to the ADD_PSYMBOL_TO_LIST macro.
102
103	* ieee-float.c:  Change "#ifdef DEBUG" to "#ifdef IEEE_DEBUG"
104	to avoid collision with the DEBUG for ADD_PSYMBOL_VT_TO_LIST.
105
106	* partial-stab.h, symfile.h:  Move definitions of the macros
107	ADD_PSYMBOL_TO_LIST and ADD_PSYMBOL_ADDR_TO_LIST from
108	partial-stab.h to symfile.h.  They aren't stab specific.
109	Change ADD_PSYMBOL_VT_TO_LIST to use memcpy rather than strncpy.
110
111Tue Dec 24 11:38:08 1991  John Gilmore  (gnu at cygnus.com)
112
113	* Makefile.in:  Roll VERSION to 4.3.2.
114
115Mon Dec 23 13:54:35 1991  Per Bothner  (bothner at cygnus.com)
116
117	* m68k-opcode.h, mips-opcode.h, sparc-opcode.h:  Deleted.
118	* m68k-pinsn.c, mips-pinsn.c, sparc-pinsn.c:
119	Include <opcode/FOO.h> instead of <FOO-opcode.h>.
120
121	* symtab.h, symtab.c, coffread.c, dwarfread.c, symmisc.c,
122	dbxread.c:  The TYPE_CPLUS_SPECIFIC structure is now only
123	allocated when it is needed.  Until it is needed, it points
124	to a shared statically allocated structure.
125
126	* buildsym.h, buildsym.c, dbxread.c: Remove the kludgy code
127	in read_ofile_symtab to recognize two initial N_SO stabs,
128	and let process_on_symbol handle it.  This is cleaner, more
129	efficient, and lets mipsread.c share the same code.
130
131	* symfile.h, partial-stab.h:  Move ADD_PSYMBOL_VT_TO_LIST
132	and related macros to here ...
133	* dbxread.c: ... from here.
134	* symmisc.c:  Move the "overflow" handling from
135	ADD_PSYMBOL_VT_TO_LIST macro into new function extend_psymbol_list.
136	* dwarfread.c:  Re-write add_psymbol_to_list to use
137	ADD_PSYMBOL_VT_TO_LIST macro.
138
139	* mipsread.c: Extend mipsread.c to handle stabs-style symbols
140	encapsulated in ecoff symbols.  This enable full g++ debugging.
141	* partial-stab.h:  Move the code for pre-scanning symbols
142	and building psymtabs to an include file, out from dbxread.c.
143	This way, the same code can also be used by mipsread.c.
144	* dbxread.c, buildsym.h:  Various changes to allow some functions
145	to be used by mipsread.c (also some arguable stylistic changes).
146
147	* tm-mips.h:  Define BLOCK_ADDRESS_ABSOLUTE, at least for now,
148	since mips-tfile puts relocatable addresses into LBRAC/RBRAC
149	stabs.
150
151	* mipsread.c:  Replace code to handle ambiguous tag blocks.
152	Instead of allocating a TYPE_CODE_UNDEF, guess (by looking
153	at types and offsets) if a tag is a struct, union, or enum.
154	Still patch it later if we find out for sure.
155	* mipsread.c:  In various ways, replace Forin's
156	ideo-syncratic code by code that fits better with the
157	rest of gdb, for both stabs-based and ecoff-based symtabs.
158	E.g.  use end_psymtab; don't do extra passes over FDR table to
159	pre-partition global data; don't use external symbols to
160	create static/global symbols (just put them in the
161	misc_vector); use ADD_PSYMBOL_TO_LIST macro; don't
162	sort psymtabs or symtabs; use obstacks more.
163
164	* symtab.c, mipsread.c, dbxread.c, buildsym.c:
165	ANSIfy: Replace bcopy by memcpy, bzero by memset.
166
167Sun Dec 22 19:31:04 1991  Fred Fish  (fnf at cygnus.com)
168
169	* solib.c (locate_base):  Fix uninitialized variable that was
170	causing return of random value to callee.
171
172	* config/mh-amix, config/mh-i386v4:  Change to find alloca by
173	compiling and linking alloca.c, even when it is not strictly
174	required.  Also arrange to link with -ltermlib rather than
175	-ltermcap.
176
177	* Makefile.in:  Move TERMCAP definition to prior to inclusion
178	of host makefile fragments so it can be overridden.
179
180Fri Dec 20 16:33:39 1991  John Gilmore  (gnu at cygnus.com)
181
182	* xcoffread.c (read_symbol_lineno):  Logic error in incrementing
183	symbol table entry number.  (From Metin Ozisik.)
184
185Fri Dec 20 11:36:38 1991  Fred Fish  (fnf at cygnus.com)
186
187	* config/mh-i386v4:  Change XM_CLIBS to "-lc /usr/ucblib/libucb.a"
188	so compiles with native compilers (without builtin alloca) can
189	pick up the version from the bsd emulation library.  However, we
190	search the standard C library first so we don't pick up lots of
191	other broken stuff from libucb.a, that we *don't* want.
192
193	* configure.in, tm-amix.h, tm-i386v4.h, xm-amix.h, xm-i386v4.h:
194	Change svr4 references to sysv4.
195
196	* source.c:  Move declaration of external function index to
197	front of file so it is in scope for all references.
198
199	* utils.c (error, fatal):  Make definitions consistent with
200	defs.h declarations (declared as "volatile void").
201
202Fri Dec 20 10:55:36 1991  John Gilmore  (gnu at cygnus.com)
203
204	* rs6k-opcode.h:  Bugfix sfe and stbrx.  By Al Kossow.
205
206Wed Dec 18 17:09:06 1991  Stu Grossman  (grossman at cygnus.com)
207
208	* command.h, defs.h, eval.h, expression.h, remote-sa.sparc.c,
209	sparc-tdep.c, symtab.h, target.h, value.h, vx-share/ptrace.h,
210	vx-share/xdr_ptrace.h, vx-share/xdr_rdb.h:  ANSIfy enums.
211
212Mon Dec 16 12:31:46 1991  Fred Fish  (fnf at cygnus.com)
213
214	* config/mt-amix, config/mt-i386v4:  Add solib.o to TDEPFILES
215	for these SVR4 systems.
216
217	* symfile.c (symbol_file_add):  When verbose is set, print
218	the names of files from which symbols are being loaded, as
219	when from_tty is true.
220
221	* solib.c:  Completely reorganized (rewritten) to support
222	SVR4 shared libraries in a manner very close to the original
223	SunOS implementation.  This support is expected to change and
224	become more general at some future time.  The SVR4 version
225	does not yet work for attached processes, for example.
226
227	* dwarfread.c:  Arrange in dwarf_build_psymtabs() for the
228	relocation address to be valid whether or not symbols are
229	being read from a shared library or an executable.  Use the
230	relocation address recorded in the psymtab when reading
231	full symbol tables (in read_ofile_symtab).  Ensure that the
232	relocated address ranges are recorded in partial symtabs.
233
234	* elfread.c:  Add new function elf_interpreter() to return the
235	string from the ELF ".interp" section.  This is the interpreter
236	that the kernel tries to run and feed the executable to.
237	Expand arguments to record_misc_function to include a type arg.
238	Modify elf_symtab_read() to supply the type arg, and to do symbol
239	relocations for symbols read in from shared libraries.
240
241	* procfs.c:  Add new functions proc_base_address() and
242	proc_address_to_fd(), used by shared library support.
243
244	* tm-svr4.h:  Add macros to support SVR4 shared libraries.
245	Definitions for SOLIB_ADD, SOLIB_CREATE_INFERIOR_HOOK,
246	CLEAR_SOLIB, and DISABLE_UNSETTABLE_BREAK.
247
248Fri Dec 13 20:11:26 1991  John Gilmore  (gnu at cygnus.com)
249
250	* infrun.c, remote-eb.c, remote-nindy.c, remote-vx.c:  Remove
251	unused START_INFERIOR_HOOK.
252
253	* remote-eb.c:  Change timeout to 24 seconds (*10 fits in byte)
254	to account for slow loading from floppies.
255	(eb_create_inferior):  New fn, from eb_start and
256	nindy_create_inferior.
257	(eb_close):  Only use log_file if nonzero.
258	(eb_xfer_inferior_memory):  If not writing, then read!
259	(eb_read_inferior_memory, eb_write_inferior_memory):  Return length.
260	(eb_kill):  A new no-op.
261	(eb_mourn_inferior):  Remove breakpoints, then generically weep.
262
263Fri Dec 13 16:09:23 1991  Fred Fish  (fnf at cygnus.com)
264
265	* breakpoint.c, findvar.c, infrun.c, putenv.c, stack.c:  Fix
266	miscellaneous comparisons of integer with NULL that elicit
267	compiler warnings about comparison of integer with pointer, when
268	NULL is ((void *) 0) rather than just a bare 0.
269
270Wed Dec 11 13:02:58 1991  John Gilmore  (gnu at cygnus.com)
271
272	* breakpoint.c (breakpoint_re_set_one):  Disable each breakpoint
273	while we reset it, in case of problems.  Print breakpoint number
274	in error messages.
275
276	* buildsym.c (read_struct_type):  Avoid sun3 compiler bug with
277	foo[--n].
278
279	* source.c (find_source_lines): If getting file mod time fails,
280	don't warn.
281
282	* target.c (target_xfer_memory):  If errno is set, return it,
283	rather than EIO.
284
285Tue Dec 10 04:07:22 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
286
287	* Makefile.in: infodir belongs in datadir.
288
289Sun Dec  8 21:13:33 1991  Michael Tiemann  (tiemann at sphagnum.cygnus.com)
290
291	* symtab.h (struct fn_field): Add new fields `is_private',
292	`is_protected', `is_stub', making room by reducing the size of
293	`voffset'.
294	(struct fn_fieldlist): Delete the fields `private_fn_field_bits'
295	and `protected_fn_field_bits'.
296	(TYPE_FN_{PRIVATE,PROTECTED}_BITS): Deleted.
297	(SET_TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
298	(TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
299	(TYPE_FN_FIELD_{STUB,PRIVATE,PROTECTED}): New macros.
300	* valops.c, valprint.c, symtab.c: All callers updated.
301
302	* buildsym.c (read_struct_type): Delete the `visibility' field
303	from `struct next_fnfield', and rework code so that visibility
304	info is stored into the fn_field directly.  Also, hacked to set
305	TYPE_FN_FIELD_STUB for both static and normal member functions.
306
307Sat Dec  7 18:13:11 1991  Fred Fish  (fnf at cygnus.com)
308
309	* i386-tdep.c:  Fix a problem on i386 systems where buffered code
310	stream access was failing to take into account the minimum size
311	granularity of the code section.  For now, the buffering is simply
312	disabled.  There is a similar problem in the i386 disassember code
313	that has not yet been fixed (FIXME).
314
315	* gmalloc.c:  Use macros to hide some of the ugly casting required
316	in the previously applied fix for pointers with high bits set.
317
318Sat Dec  7 16:49:35 1991  John Gilmore  (gnu at cygnus.com)
319
320	* Makefile.in:  Roll VERSION to 4.3.1.
321
322Sat Dec  7 04:12:35 1991  John Gilmore  (gnu at cygnus.com)
323
324	GDB-4.3 release!
325
326	* Makefile.in:  Roll VERSION to 4.3
327	* README, TODO, WHATS.NEW, depend:  Update.
328
329	* inflow.c (terminal_inferior):  Avoid error msg if attached.
330
331	* gmalloc.c:  Fix bug that causes malloc & free to
332	fail on systems where pointers have the high bit set (0x800efcf0
333	for example).  The problem is that the difference between two
334	pointers is a signed integer, so the computation
335
336	        (char *) 0x800efcf0 - (char *) 0
337
338	yields a negative value.  The sign of the result of the modulus
339	operator is machine dependent for negative operands, thus it is
340	possible for it to end up negative.  From Fred Fish.
341
342Sat Dec  7 00:00:15 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
343
344	* Makefile.in: install using INSTALL_PROGRAM and INSTALL_DATA.
345	  added clean-info.  added some standards.text support and made it
346	  look like our other Makefiles.
347
348	* configure.in: mark this directory target dependent.  configure
349	  now runs entirely in objdir so make existence tests and
350	  references against ${srcdir}.
351
352Fri Dec  6 08:30:36 1991  Fred Fish  (fnf at cygnus.com)
353
354	* dwarfread.c (enum_type, struct_type):  Fixes for opaque and
355	anonymous enumerations, structures, and unions.  Now passes all
356	the current gdb test suite tests.
357
358Thu Dec  5 22:46:13 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
359
360	* Makefile.in: idestdir and ddestdir go away.  Added copyrights
361	  and shift gpl to v2.  Added ChangeLog if it didn't exist. docdir
362	  and mandir now keyed off datadir by default.
363
364Thu Dec  5 21:53:21 1991  John Gilmore  (gnu at cygnus.com)
365
366	* symtab.c (decode_line_1):  If SKIP_PROLOGUE leaves us in
367	mid-line, be more careful about possibly advancing to the next line.
368
369Thu Dec  5 18:59:51 1991  Michael Tiemann  (tiemann at cygnus.com)
370
371	* cplus-dem.c (cplus_demangle): Call `string_need' when
372	null-terminating a partially-computed string.
373
374Thu Dec  5 18:19:43 1991  Fred Fish  (fnf at cygnus.com)
375
376	* dwarfread.c (enum_type):  Build a correct TYPE_NAME, add a
377	symbol to the symbol table for each member of the enum.
378
379	* dwarfread.c (struct_type):  Build a correct TYPE_NAME.
380
381	* dwarfread.c (add_enum_psymbol):  New function to extract enum
382	member names and add them to the partial symbol table while
383	building partial symbol tables.
384
385Thu Dec  5 17:31:05 1991  John Gilmore  (gnu at cygnus.com)
386
387	* symtab.c (check_stub_method):  Must allocate two extra argument
388	slots (one for `this', one for arglist terminator).
389
390Thu Dec  5 10:51:05 1991  Fred Fish  (fnf at cygnus.com)
391
392	* inflow.c (child_terminal_info): Supply missing '"' character.
393
394	* buildsym.c (define_symbol):  Supply missing parenthesis.
395
396Thu Dec  5 03:34:21 1991  John Gilmore  (gnu at cygnus.com)
397
398	* coredep.c (fetch_core_registers):  Fencepost error.  Fixed by
399	Jay Lepreau <lepreau@cs.utah.edu>.
400
401	* inflow.c:  Remember whether GDB has a terminal.  Avoid switching
402	terminals back and forth if we don't have one.
403
404	* c-exp.y (parse_number):  Zero is not an unsigned int constant!
405	* dbxread.c (read_dbx_symtab):  Enum type numbers can be in (1,2) form.
406
407	Improve type parsing.
408	* buildsym.c (define_symbol, read_range_type): Add
409	long_kludge_name that passes the names of range types being
410	defined, down to where we must choose between 'int' and 'long'
411	variants.  This fails on Sun C anyway since the compiler itself is
412	confused between int and long.
413	(read_array_type, cleanup_undefined_types):  Correct the size of
414	array type whose element-type size isn't immediately known.
415
416	Early preparation to blow away many builtin types, building them
417	on the fly as needed.  Don't compare types to builtin types with
418	==; examine the relevant fields instead.
419	* coffread.c (process_coff_symbol: C_ARG, C_REGPARM):  Avoid ==.
420	* buildsym.c (define_symbol, case 'p'):  Avoid ==.

424
425	* symmisc.c (printpsyms_command):  Reduce redundancy, and put all

429
430	* dwarfread (enum_type):  Arrange for the order of enumeration
431	members to match the source code order; not the order in the
432	Dwarf information, which is explicitly reverse order.

469
470	* sparc-xdep.c:  Force tm-file as tm-sparc.h, to make it compile

472	general solution.
473
474Mon Dec  2 11:04:05 1991  Per Bothner  (bothner at cygnus.com)
475
476	* mips-tdep.c (init_extra_frame_info):  Float register
477	'i' has gdb-internal number 'FP0+i', not '32+i'.
478	* mipsread.c (new_symbol):  Translate g++ special

553
554	* coffread.c (anonymous unions):  Allocate a cplus structure.

563
564	* inflow.c (terminal_inferior):  Check the results of ioctl's, and
565	print a message if any of them fail.
566	(terminal_ours_1):  Store result of ioctl's for debugging, but
567	don't print (the terminal isn't ours...).
568

570	pointer.
571
572	* m2-exp.y (MAX, MIN):  Rename to MAX_FUNC, MIN_FUNC to avoid
573	conflicts with system header files.
574
575Fri Nov 22 08:27:40 1991  John Gilmore  (gnu at cygnus.com)
576
577	* Roll VERSION to 4.2.95.
578

589	at #define's, followed by defs.h and then the tm-file.
590	* Makefile.in:  Remove spaces after 'ignore exit code' - flags.
591	Late-model BSD 'make's don't cope with them.
592
593Thu Nov 21 23:48:56 1991  John Gilmore  (gnu at cygnus.com)
594
595	* Makefile.in:  Roll new files into various lists.
596
597Thu Nov 21 18:26:11 1991  Fred Fish  (fnf at cygnus.com)
598
599	* dwarfread.c (struct_type):  Must initialize the c++ specific
600	portion of union types as well as struct types, since gdb attempts
601	to reference the c++ specific info for both types.
602
603Thu Nov 21 10:23:52 1991  John Gilmore  (gnu at cygnus.com)
604
605	* Makefile.in: Roll VERSION to 4.2.90.

626
627Wed Nov 20 18:35:56 1991  John Gilmore  (gnu at cygnus.com)
628
629	* Remove gdb/hp-include.  Support for HP a.out oddities should be
630	in BFD, not in GDB.  Move gdb/hp-include/a.out.h to include/a.out.hp.h.
631
632	* infptrace.c, tm-sun386.h:  Cashier <a.out.gnu.h>, remove refs.
633
634	* configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
635	Makefile fragments for various hosts and targets now come from
636	gdb/config/mh-* and gdb/config/mt-*.  This is for consistency with
637	other config setups.
638
639	* rs6000-pinsn.c, rs6k-opcode.h:  Clean up.
640	* rs6k-opcode.def:  Delete.

645	attribute still used by at least one AT&T compiler, and possibly
646	more.
647
648Tue Nov 19 07:53:55 1991  Fred Fish  (fnf at cygnus.com)
649
650	* dwarfread.c (enum_type, struct_type):  Ignore names invented by
651	helpful compilers for anonymous structs, unions, and enums.
652
653	* c-exp.y, m2-exp.y:  Add defines for yymaxdepth, yy_yys, and
654	yy_yyv, so multiple parsers produced by SVR4 versions of yacc
655	can coexist in the same executable without collision.
656
657	* symtab.h:  Add declaration for lookup_template_type() to kill
658	compiler warnings about conversions from int to pointer.
659
660Mon Nov 18 17:45:18 1991  Fred Fish  (fnf at cygnus.com)
661
662	* procfs.c:  Move inclusion of defs.h to before param.h, as in
663	all the other source files that include both.  This is required
664	to supply some typedefs that are used in files included by param.h.
665
666	* m68k-tdep.c (m68k_skip_prologue):  Add generic m68k support for
667	skipping function prologues, ala the other cpu families (i386,
668	mips, m88k, etc).  Add the ability to skip movm and fmovm
669	instructions in the prologues.  Still needs support for profile
670	(-p compiled) prologue sequences (FIXME).
671
672	* tm-68k.h:  Change SKIP_PROLOGUE macro to use the new generic
673	m68k prologue skipping function by default.
674
675	* tm-altos.h, tm-isi.h:  Continue to use the old definition of
676	SKIP_PROLOGUE.
677
678Mon Nov 18 15:12:45 1991  John Gilmore  (gnu at cygnus.com)
679
680	* Makefile.in:  Remove tdesc stuff, and extra blanks before colons.
681	* blockframe.c:  Remove tdesc-related code.  Default
682	FRAME_CHAIN_COMBINE.
683	* infrun.c:  Remove tdesc-related code.

685	of defaultable things.
686	* tm-m88k.h:  New file, common to all Moto 88k target configs.
687	Derived from tm-delta88.h.
688	* tm-delta88.h:  Use it.
689	* xm-m88k.h:  Common file for 88K hosts.  Remove obsolete stuff.
690	* xm-delta88.h:  Use it.
691	* tm-*.h:  Remove FRAME_CHAIN_COMBINE macros, since all are
692	default.
693	* coffread.c:  Remove tdesc stuff.
694	* tconfig/delta88, tconfig/m88k:  Remove tdesc stuff.
695	* xconfig/m88k:  Rename tm-88k.h to tm-m88k.h.

697Mon Nov 18 13:51:37 1991  Per Bothner  (bothner at cygnus.com)
698
699	* source.c (open_source_file):  If openp fails, try again
700	using just the base (non-directory) part of the filename.
701	This solves various annoying problems, such as when the
702	source was compiled with an absolute pathname - and the
703	source files have moved.  Or if the source was compiled
704	using a relative pathname, it can be more convenient
705	to just specific the source directory to the dir command.
706
707Mon Nov 18 00:04:41 1991  Fred Fish  (fnf at cygnus.com)
708
709	* cplus-dem.c (munge_function_name):  Add missing third arg to

717
718	* symtab.h (struct type): Moved C++-specific fields into new type
719	`struct cplus_struct_type'.  Now takes 10% less memory.  Many
720	macros changed.
721	* symtab.c (init_type): Don't set fields belonging to
722	TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
723	* buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
724	TYPE_CODE_STRUCT.
725	(read_struct_type): Ditto.  Also, add comments about how we can
726	deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
727	* coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
728	TYPE_CODE_STRUCT.
729	(read_struct_type): Ditto.
730	* dwarfread.c (struct_type): Ditto.
731
732	* symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
733	(lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.
734	(lookup_reference_type): Ditto.
735
736	* cplus-dem.c: Many changes made to handle decoding of
737	ANSI-mangled names.
738	* symtab.c (gdb_mangle_name): Mangle/demangle ANSI-mangled names
739	as well.
740

742
743	* mipsread.c (parse_partial_symbols):  patch to keep DEC C
744	compiler from making gdb bomb out.  Thanks to Ed Santiago!
745

747
748	* symfile.c:  Add function compact_misc_function_vector() to
749	remove duplicate misc function vector entries.  See comments
750	in source for why this is necessary/desirable.
751
752	* dwarfread.c:  Add misc function type parameter to internal
753	record_misc_function().  Remove calls to init_misc_bunches()
754	and condense_misc_bunches(), these are now done in elfread.c.
755
756	* elfread.c:  Add support for reading bfd canonical symbol tables
757	and generating misc function vector entries for global and
758	absolute symbols.  Do calls to init_misc_bunches() and
759	condense_misc_bunches() where they will enclose all calls to
760	record_misc_function(), including those in dwarfread.c.
761
762Thu Nov 14 17:02:11 1991  Roland H. Pesch  (pesch at cygnus.com)
763
764	* doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
765	(roffable documentation).
766	* doc/gdb.texinfo: embedded hints (as comments) for better
767	texi2roff conversion.
768

772	that shuffle parameters into other regs.
773	* symtab.c (decode_line_1):  Fix bug introduced in Per's change
774	of Nov 12th.
775

777
778	* Makefile.in, xconfig/delta88 made it install a sysV manual page;
779	gdb.z into the right place.
780
781Wed Nov 13 16:45:13 1991  John Gilmore  (gnu at cygnus.com)
782
783	Motorola 88000 port without tears, I mean without tdescs.
784
785	* m88k-tdep.c:  Blow away all tdesc stuff.
786	Provide functions for all the frame-related macros in
787	tm-delta88.h.  Adopt i960-style EXTRA_FRAME_INFO.
788	(examine_prologue, frame_find_saved_regs, skip_prologue):  borrow
789	from i960-tdep.c and adapt to the function prologues on the 88k.
790	(read_next_frame_reg):  Borrow from mips-tdep.c.
791	FIXME:  frame_locals_address should go away.
792
793	* tm-delta88.h:  Dump all the tdesc stuff.
794	Macros for all frame-related stuff call fns of same name.
795	Remove duplicated definitions.  FP_REGNUM becomes same as
796	SP_REGNUM.
797
798	* xm-88k.h:  Eliminate lots of library dependencies, now handled
799	in libiberty.  Eliminate KDB nonsupport.
800
801	* doc/gdbint.texinfo:  Add rudiments on frames.  FIXME, add more.
802
803
804	* stack.c (frame_info):  Mark frameless functions.
805	Print locals address (FIXME, remove if same).
806	* blockframe.c:  Comment changes, FIXME after.
807	* coffread.c:  Even without TDESC, need to zap "@" symbols.
808	Don't register for wierd format names; change the names in BFD.
809
810	* alloca.c, language.c, tdesc.c:  Lint.
811	* tdesc.c, tdesc-lib: FIXME:  remove these.
812

815	* Makefile.in:  Add tdesc library support.  Fixups to lint,
816	copying.c rules.
817

819
820	* symtab.c (decode_line_1):  Remove spurious call to operator_chars.
821
822	Allow setting breakpoints on C++ destructors.
823	* valops.c (destructor_name_p):  Don't check TYPE_HAS_DESTRUCTOR,
824	since it lies.  Rely on callers to catch missing destructors.
825	* symtab.c (decode_line_1):  For example (see above), here.
826	* buildsym.c, symtab.h:  Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
827	flags since they are no longer used.
828
829	Fixes to support C++ methods with functional parameters.
830	* c-exp.y (func_mod rule):  Allow (and ignore) list of parameter
831	types in a function type.
832	* eval.c (parse_and_eval_type), value.h:  New function,
833	parse_and_eval_type, is based on old code from check_stub_method.
834	But don't actually evaluate the cast, since that calls
835	value_cast(), whcih may fail.  Just extract the type
836	from the parsed expression.
837	* values.c (check_stub_method):  While looping through the
838	arguments, adjust depth *after* parameter has been handled.
839	Replace call and setup of parse_and_eval with new function

869
870	* elfread.c:  Remove the register_addr() stub now that it is no
871	longer needed.
872
873	* procfs.c:  Move misplaced #endif for ATTACH_DETACH.  Add new
874	fetch_core_registers() function for core file support.
875
876Sat Nov  9 13:37:57 1991  Fred Fish  (fnf at cygnus.com)
877
878	* dwarfread.c (dwarf_psymtab_to_symtab):  Remove leftover call
879	to do_cleanups() which resulted from a previous change.
880
881	* elfread.c:  Re-enable compilation of register_addr() stub
882	whenever it is not supplied by coredep.c
883

912	Pass objfile.  Change callers.
913	(fill_symbuf, SWAP_SYMBOL):  Take bfd as arg.

950	* symtab.h:  partial_symbol_table has no symfile_name member now.
951	(fn_fieldlists voffset):  avoid non-int bitfield.
952	(struct symtab):  Add objfile * and objfile_chain * of symtabs.
953	(struct partial_symtab):  Add objfile * and objfile_chain * of
954	psymtabs.  Remove symfile_name.
955
956	* symmisc.c:  Lose free_all_symtabs, free_all_psymtabs.
957	(printsyms_command):  Rename from print_symtabs.  Add selective

962
963	* symfile.h, symfile.c, symtab.h:  Lint
964
965Fri Nov  8 23:38:48 1991  John Gilmore  (gnu at cygnus.com)
966
967	* command.c:  Include param.h.
968	* defs.h (warning_setup, warning):  Declare.

973
974Thu Nov  7 18:26:15 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
975
976	* Makefile.in: link with libiberty after libreadline, since
977	readline might want something in libiberty.
978	* m88k-xdep.c: Fixed the register offsets in the ptrace_user
979	struct for BCS 88k machines.
980	* xm-m88k.h: don't define USIZE if already defined.
981	* configure.in: Added delta88 target.
982
983Thu Nov  7 04:51:19 1991  John Gilmore  (gnu at cygnus.com)
984
985	* am29k-pinsn.c, am29k-opcode.h:  Fix decoding of mtacc, dmac, fmac.
986
987	* tm-*.h:  Remove READ_DBX_FORMAT, COFF_FORMAT, and
988	READ_MIPS_FORMAT, which have been unused since BFD.  Still
989	remaining is COFF_NO_LONG_FILE_NAMES.
990	* tm-sun3.h, tm-altos.h:  Remove detritus accidentally left from
991	function calling code moved to m68k-tdep.c.
992
993Wed Nov  6 17:21:59 1991  John Gilmore  (gnu at cygnus.com)
994
995	* coffread.c:  Eliminate c_nsyms in favor of c_naux.
996	Complain if no auxents on .bf and .ef FCN symbols, and assume
997	lots of line numbers.
998	(init_linenos, enter_linenos):  Use a sentinel at the end of the
999	read-in linenos, to make for a fast, safe loop-end test.
1000
1001Wed Nov  6 02:54:08 1991  Steve Chamberlain  (sac at cygnus.com)
1002
1003	* coffread.c (read_coff_symtab): coffread used to rely on the
1004	x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
1005	function. Two of the formats I'm using (29k and 88k) don't seem to
1006	set it. Ths patch to fcn_last_line and (enter_linenos) is an
1007	attempt to use the actual size of the linno table in the file to set
1008	the number of linenos to process.
1009
1010Tue Nov  5 22:47:46 1991  Steve Chamberlain  (sac at cygnus.com)
1011
1012	* Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
1013	mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
1014	are created in place, so the mv fails, then the make continues.
1015
1016Tue Nov  5 16:47:47 1991  Per Bothner  (bothner at cygnus.com)
1017
1018	Add C++ as a separate language.
1019	* defs.h (enum language): Add language_cplus.
1020	* dwarfread.c (end_symtab):  Support language_cplus.
1021	* c-exp.y:  Add new struct language_defn cplus_language_defn.
1022	Don't set c to be the default language (see main.c).
1023	* c-exp.y (yylex):  Only look for field of this if
1024	language is C++.  (First difference from C!)
1025	* language.c:  Add case branches for C++ (currently, all
1026	the same as C).  Also, add c++ to "usage" note for "set lang".
1027	* valprint.c (typedef_print).  Add case branches for C++.
1028	* main.c (main):  New way to set initial language:  Look at
1029	file extension of psymtab containing main().  (Same as we
1030	do for symtabs, but avoid loading the symtab yet.)
1031	* symtab.c: New routine find_main_psymtab(), used by main()
1032	to set initial language.
1033	* symfile.c (allocate_symtab):  Move code for mapping file
1034	extensions-> languages to new deduce_language_from_filename().
1035
1036	Fix a C++ problem when looking for methods in super-classes.
1037	There was confusion between base and derived types.
1038	* valops.c (value_fn_field):  Change function interface.
1039	* values.c:  Use new value_fn_field interface.
1040
1041Mon Nov  4 10:49:33 1991  Per Bothner  (bothner at cygnus.com)
1042
1043	* infrun.c:  Fixed typo in comment.
1044	* utils.c:  All the v*fprintf emulation is now in libiberty,
1045	so we can get rid of some junk.
1046	* xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
1047	xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
1048	* m68k-pinsn.c (print_insn_arg):  Support BB/BW/BL
1049	type operands, as used by branch instructions.
1050	* gmalloc.c: Fix prototype of memcpy.
1051	* elfread.c: Comment out register_addr, since it conflicts
1052	with the one in coredep.c.
1053	* buildsym.h:  Remove extern declarations of two functions
1054	that are really static in buildsym.c.
1055	* tm-mips.h: Add symbolic names for more registers.
1056	* mips-xdep.c (store_inferior_registers): Use new register names.
1057	* xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
1058	only used for core files, not ptrace.  Therefore,
1059	the KERNEL_U_ADDR hack is no longer needed.
1060	The mapping to ptrace number is now in in mips-xdep.c.
1061	* mips-xdep.c:  Define REGISTER_PTRACE_ADDR (using the
1062	mapping from the old REGISTER_U_ADDR), and use it
1063	in {fetch,store}_inferior_registers.
1064	* mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
1065	* mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
1066	Save/restore FP regs correctly (?).
1067	* dbxread.c: Remove duplicate define_symbol and type_synonym_name
1068	(these had been previously moved to buildsym.c).
1069	Hence, define_symbol becomes extern instead of static.
1070	* buildsym.c (read_struct_type):  Comment out bogus handling
1071	of C++ operator methods.  Minor hacking of reading of class
1072	contexts. Make define_symbol non-static, so dbxread.c can call it.
1073
1074Fri Nov  1 11:05:47 1991  John Gilmore  (gnu at cygnus.com)
1075
1076	* mipsread.c (read_mips_symtab, read_the_mips_symtab):  Use real
1077	filename with error messages.
1078	* stack.c (frame_select_command):  Rename to select_frame_command
1079	to avoid "fr" and "fra" having nonunique completions.
1080	* symfile.c (sort_symtab_syms):  Ignore sort of zero symtab *.
1081	(symfile_init):  Print file format name when unable to handle it.
1082	(free_named_symtabs):  Use BLOCKVECTOR rather than obsolete BLOCKLIST.
1083	* symmisc.c (free_symtab):  Only free linetable if nonzero.
1084	* symtab.h:  Remove obsolete BLOCKLIST macros.
1085
1086Thu Oct 31 18:12:43 1991  Stu Grossman  (grossman at cygnus.com)
1087
1088	* infrun.c (wait_for_inferior):  another stepi/nexti fix.  Ensure
1089	that stop_step is 1 at bottom of main loop.  I don't know why this
1090	needs to be done, but it helps me sleep better at night.
1091
1092Sun Oct 27 18:18:39 1991  Stu Grossman  (grossman at cygnus.com)
1093
1094	* main.c (initialize_history):  Read history after reading all
1095	init files.
1096
1097Sun Oct 27 14:09:25 1991  John Gilmore  (gnu at cygnus.com)
1098
1099	* buildsym.c:  Break out initial malloc sizes.
1100	(record_line):  Record directly in a subfile.  Alloc on demand.
1101	(compare_line_numbers):  Add from xcoffread.c.
1102	(end_symtab):  New params say whether to sort pendings and
1103	linetable.  Patch block stabs if defined.  Shrink linetable before
1104	allocating the symtab.
1105	* buildsym.h:  Delete line_vector* and prev_line_number.  Add
1106	global_stabs and file_stabs for xcoffread.
1107	* dbxread.c (start_subfile):  Move to buildsym.  Change above calls.
1108	* symtab.h:  LINETABLE(symtab) can now be null.  Zap LINELIST.
1109	* symmisc.c, symtab.c:  Cope with null LINETABLEs.
1110
1111	* blockframe.c:  Pass fromleaf to INIT_EXTRA_FRAME_INFO.
1112	* tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
1113	tm-sparc.h:  Accept fromleaf parameter.
1114	* c-exp.y (yyerror):  Pass error message if given.
1115	* configure.in:  Add rs6000 host and target.
1116	* inflow.c (new_tty):  O_NOCTTY kludge for RS/6000.
1117	* symfile.h (entry_point):  Add.
1118
1119Sat Oct 26 00:16:32 1991  John Gilmore  (gnu at cygus.com)
1120
1121	* buildsym.c:  New file.  Breaks out symbol-table-building routines
1122	from dbxread.c, so they can be shared with xcoffread.c.
1123	* buildsym.h:  New file.  Declarations for buildsym.c users.
1124	* dbxread.c:  Remove large chunks into buildsym.c.
1125	* Makefile.in:  Add buildsym.c and buildsym.h.
1126
1127	* symfile.c (syms_from_bfd):  New routine.
1128	(add_symbol_file):  Call it to do the real work.
1129	(syms_from_bfd):  Initialize entry_point before calling symfile_init.
1130	* symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
1131	Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
1132
1133Fri Oct 25 10:58:16 1991  Mark Eichin  (eichin at cygnus.com)
1134
1135	* cplus-dem.c (cplus-demangle): added support for templates, static
1136	data, and the new (correct) mangling for destructors.
1137
1138	* dwarfread.c: (dwarfwarn): created a varargs version of
1139	dwarfwarn, for non __STDC__ compilers.
1140
1141	* c-exp.y: (yylex): added match for "template" token.
1142	(typebase): added TEMPLATE name '<' type '>' clause, for explicit
1143	specification of template types.
1144
1145	* symtab.c: (lookup_template_type): new function for finding
1146	templates in symbol table.
1147	(type_name_no_tag): changed to explicitly check for s/u/e at the
1148	beginning of the symbol - if it is a template, none of these will
1149	be there (but the name will still contain spaces.)
1150
1151Fri Oct 25 18:59:32 1991  Per Bothner  (bothner at cygnus.com)
1152
1153	Various fixes to improve g++ debugging.
1154	* symtab.h:  Add is_const and is_volatile flags for each method.
1155	These are bit fields - take their space from voffset,
1156	which shrinks to 30 bits.  Since voffset is now a bitfield,
1157	make it unsigned for portability.  This changes its interpretation
1158	slightly:  Static methods now have voffset 1 instead of -1,
1159	and virtual offsets start at 2, not 1.
1160	* symtab.c:  Renamed gdb_mangle_typename to gdb_mangle_name,
1161	since it now returns an entire magled method name, not just
1162	the type part.  This avoids some duplication.
1163	It also allows us to correctly mangle const and volatile
1164	methods (using the new is_const and is_volatile bit fields
1165	mentioned above).
1166	* valprint.c (type_print_base), values.c (check_stub_method):
1167	Simplify by using new gdb_mangle_name.
1168	* values.c (value_headof):  Fix to correctly handle single
1169	inheritance (actually two fixes, either of which suffices).
1170	* dbxread.c (read_struct_type):  Handle const and volatile
1171	method specifiers.
1172	* dbxread.c (read_struct_type):  Yet one more place where
1173	we must handle '\\' continuations.
1174	* valprint.c (vtbl_ptr_name): Add final '\0'.
1175
1176Fri Oct 25 16:06:38 1991  Stu Grossman  (grossman at cygnus.com)
1177
1178	* tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE):  fix output of
1179	short return values for sparc and 68k.  Patch from Paul Eggert.
1180
1181	* coffread.c, coredep.c, i386-xdep.c:  install patches for
1182	SysV/386 3.2 from Mauro DePalma.
1183
1184Fri Oct 25 02:02:13 1991  John Gilmore  (gnu at cygnus.com)
1185
1186	* core.c (core_file_info), exec.c (exec_file_info):  Print file
1187	type.  Use printf_filtered.
1188
1189	* valops.c (value_fetch_lazy):  Avoid 0-length fetches.
1190
1191Thu Oct 24 23:06:40 1991  Fred Fish  (fnf at cygnus.com)
1192
1193	* dwarfread.c:  Add casts to remove compiler warnings.
1194
1195	* tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
1196	tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
1197	tm-sun3.h:  Remove locally duplicated code for calling functions
1198	in the inferior.  The only differences were in the specific trap
1199	vectors used and whether or not an fpu was present.  These are
1200	now handled by appropriate definitions of BPT_VECTOR and
1201	HAVE_68881 respectively.  Other minor obvious cleanups.
1202
1203	* valops.c:  Correct a minor misspelling.
1204
1205	* utils.c:  Remove local BSD/USG hacks that are now in libiberty.
1206
1207	* dwarfread.c:  Remove prototype for dwarfwarn.  Does not work
1208	with <varargs.h>.
1209
1210Thu Oct 24 09:33:44 1991  John Gilmore  (gnu at cygnus.com)
1211
1212	* stack.c (frame_command):  Always print.  Use new
1213	frame_select_command to select a frame without printing.
1214
1215	* dwarfread.c:  Use <varargs.h>, since <stdarg.h> is not portable.
1216
1217Thu Oct 24 01:32:51 1991  Fred Fish  (fnf at cygnus.com)
1218
1219        * dwarfread.c: New file for DWARF debugging format support.
1220
1221	* elfread.c: New file for ELF object file format support.
1222
1223	* procfs.c: New file for SVR4 /proc (process file system) support.
1224
1225	* tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
1226	Amiga UNIX support.
1227
1228	* xm-svr4.h, tm-svr4.h: New files for SVR4 support.
1229
1230	* xm-m68k.h: New file for host machines with m68k cpu.
1231
1232	* Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
1233	Add elfread.o and dwarfread.o to OBS.
1234
1235	* symfile.h: Add "elf" to list of supported formats in comment.
1236
1237	* c-exp.y, defs.h, symtab.h, valprint.c:  Add three new builtin
1238	types to gdb, builtin_type_long_double, builtin_type_complex, and
1239	builtin_type_double_complex.  Add and use new TARGET_SHORT_BIT,
1240	TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
1241	TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
1242	TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
1243	types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
1244
1245	* infrun.c:  When using SVR4 /proc interface instead of ptrace(),
1246	call proc_set_exec_trap() to setup child to stop at first instruction.
1247
1248	* inftarg.c: When using SVR4 /proc interface, call proc_wait()
1249	rather than wait().
1250
1251	* m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
1252	supply_fpregset(), and fill_fpregset(), which are machine
1253	dependent support routines for SVR4 /proc interface.
1254
1255	* utils.c: Add warning_setup() and warning().  Warning() behaves
1256	the same as error() except that it returns normally rather than
1257	jumping back to command level.  Modules that don't want to call
1258	warning() for some reason, but want to produce their own warnings,
1259	can call warning_setup() to ensure compatibility with the way
1260	warning() and error() deal with the terminal.
1261
1262	* symtab.c: Make internal errors produce more useful messages.
1263
1264	* tm-68k.h: Move code that is duplicated in almost every single
1265	m68k based machine's configuration files to this common file.
1266	Duplications in the configuration files still need to be removed
1267	(FIXME).
1268
1269	* infrun.c (child_create_inferior): System V versions must call
1270	setpgrp() with no arguments, to comply with prototyping typically
1271	in <unistd.h>.
1272
1273	* munch: Add support for SVR4 style nm output.
1274
1275	* dbxread.c, mipsread.c symmisc.c, symtab.c:  Remove the object
1276	file specific fields from the partial symbol table structure and
1277	replace them with a pointer to private data for each different
1278	flavor of object file reader to initialize appropriately.
1279
1280Wed Oct 23 09:38:20 1991  John Gilmore  (gnu at cygnus.com)
1281
1282	* xconfig/sun[34]os4:  Add note about strstr botch on sunos4.0.3c
1283	and previous.
1284
1285	* mipsread.c (fixup_undef_type):  New function.  If a struct /
1286	union / enum is defined in a header file but nowhere else used,
1287	(by typedefing, pointer referencing or declaration) the mipsread code
1288	builds the complete tree for the structure but leaves its code as
1289	TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
1290	Guess its type based on the details of the members.
1291
1292Tue Oct 22 18:04:32 1991  Stu Grossman  (grossman at cygnus.com)
1293
1294	* infrun.c (wait_for_inferior):  Check return value from
1295	find_pc_line.
1296
1297Mon Oct 21 17:47:03 1991  Stu Grossman  (grossman at cygnus.com)
1298
1299	* infrun.c (wait_for_inferior):  fix stepi/nexti that was broken
1300	by my last edit to this routine.
1301
1302Mon Oct 21 14:27:43 1991  John Gilmore  (gnu at cygnus.com)
1303
1304	* tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
1305	FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
1306	the values before putting them into the dummy code.  (From Peter
1307	Schauer)
1308
1309Mon Oct 21 10:04:39 1991  Steve Chamberlain  (steve at rtl.cygnus.com)
1310
1311	* configure.in: added ebmon target.
1312

1324	and pass it to register_addr to locate the block of registers.
1325	* xm-mips.h:  Update KERNEL_U_ADDR for new scheme.  Cleanup a bit.
1326
1327	* dbxread.c (read_dbx_symtab, process_one_symbol):  Handle
1328	Sequent N_FN_SEQ like everybody else's N_FN.
1329
1330	* main.c:  Circumvent SCO cc bug with #if !!defined(USG).
1331	* tm-i386v.h:  #endif guck.
1332	* xconfig/i386*:  Remove -Dgetpagesize()=4096 kludge.
1333	* xconfig/i386sco:  Add HAVE_STRSTR to avoid ANSI bdeath.
1334	* xconfig/tahoe:  Add REGEX, which seems to be missing.
1335

1375	due to Larry Breed
1376
1377Fri Oct 11 23:27:06 1991  John Gilmore  (gnu at cygnus.com)
1378
1379	* tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h:  Move
1380	REGISTER_U_ADDR to corresponding xm- file.  Sugg. by Peter Schauer.
1381
1382	* symmisc.c (print_partial_symtabs):  Add printpsyms debug cmd.
1383

1385	generic routines for calling inferior functions.
1386
1387	* blockframe.c (inside_main_scope, inside_entry_scope):  New.
1388
1389	* copying.awk:  Filter formfeeds out of copying & warrantee.
1390	Make them available as `show copying' and `show warrantee' also.
1391	* main.c (print_gnu_advertisement):  Advt `show' commands.
1392
1393Thu Oct 10 17:25:47 1991  John Gilmore  (gnu at cygnus.com)

1400
1401	* mipsread.c, coffread.c:  initialise TYPE_VPTR_FIELDNO to -1.
1402	This avoids coredumps under `set print object on' in value_headof
1403	(called erroneously by value_from_vtable_info) for `p &struct'
1404	or `p *struct'.  From Peter Schauer.
1405
1406Mon Oct  7 00:06:52 1991  John Gilmore  (gnu at cygnus.com)
1407
1408	* Makefile.in:  Roll version to 4.1.2.
1409	* dbxread.c:  Use aout64.h, not a.out.gnu.h.  Get external symbol entry
1410	size from BFD (but, FIXME, we don't yet read external nlists's and
1411	convert them to internal nlists's before handling them -- we still
1412	assume they have the same size and alignment.)  Use SET_NAMESTRING
1413	everywhere useful.
1414	* exec.c (exec_file_command):  Move dead coff-encapsulation code
1415	to BFD.
1416	* m88k-tdep.c, m88k-xdep.c:  Remove encap test and #inc <a.out.h>.

1424
1425	More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1426	* mips-xdep.c (store_inferior_registers):  Don't try to
1427	write the (pseudo) FP.
1428	* mipsread.c (parse_partial_symbols):  Improved algorithm for

1441
1442Thu Oct  3 09:33:26 1991  John Gilmore  (gnu at cygnus.com)
1443
1444    	* dbxread.c, coffread.c:  static-ize functions that were
1445	gratuitiously external.  (From Fred Fish.)
1446
1447	* c-exp.y:  sym->class to SYMBOL_CLASS (sym).
1448
1449	* dbxread.c (dbx_lookup_type):  Keep doubling size of typevector
1450	until it is large enough.
1451
1452	* dbxread.c (read_type):  Handle error case slightly better.
1453	Make complaint message not C++-specific.
1454

1456
1457	* infrun.c (wait_for_inferior):  Fix step/next so that you only
1458	stop at the beginning of a new line.  This fixes various problems
1459	with for loops, nested if-else's and switch statements.
1460
1461Tue Oct  1 06:33:55 1991  John Gilmore  (gnu at cygnus.com)
1462
1463	* symtab.c (lookup_symtab_1, lookup_symbol):  "fatal" errors
1464	between symtabs and psymtabs become ordinary error()s.
1465
1466	* dbxread.c (read_dbx_symtab):  Relocate end_of_text_addr
1467	properly, making "end pc" correct in shared lib psymtabs.
1468	(From Guy Harris <guy@auspex.com>.)
1469
1470Mon Sep 30 13:15:31 1991  John Gilmore  (gnu at cygnus.com)
1471
1472	* dbxread.c:  Enable, but soften, const_vol_complaint.
1473	(read_dbx_symtab):  N_STSYM and N_LCSYM define static vars.
1474	Ditto Gould N_NBSTS and N_NBLCS.  Also, all types in the psymtab
1475	should be file-scope, not global.
1476	(read_struct_type):  Remove ancient multiple-inheritance warning.
1477	(read_range_type):  Check base type, complain & patch if undefined.
1478	* stack.c (frame_info):  Demangle the function name in `info stack'.
1479	(From Peter Schauer)
1480
1481Sat Sep 28 10:02:33 1991  John Gilmore  (gnu at cygnus.com)
1482
1483	* eval.c (evaluate_subexp_for_address):  Don't use
1484	TYPE_POINTER_TYPE directly (it might be zero if this type has
1485	never had a pointer created before); use lookup_pointer_type.
1486	* symtab.c (lookup_method_type):  Arguments were swapped in all
1487	callers, so fix it here.  I'm amazed this worked at all!
1488
1489Fri Sep 27 18:09:31 1991  John Gilmore  (gnu at cygnus.com)
1490
1491	* c-exp.y, m2-exp.y:  Define more yysymbols that happen to be
1492	"bss" rather than "data" symbols, but which still conflict.
1493	* m2-exp.y:  Lint.
1494
1495	* coffread.c (coff_symfile_read):  Use xmalloc, not malloc.
1496	* core.c (core_files_info):  Shorten output.
1497	* exec.c (exec_files_info):  Ditto.
1498	(build_section_table):  Ignore zero-length sections.
1499	* language.c, printcmd.c:  Lint.
1500	* language.h (get_frame_language):  Declare.
1501	* saber.suppress:  update.
1502	* stack.c (find_relative_frame):  Remove complex code that was

1510	kludgey.
1511
1512	* nindy-tdep.c (nindy_frame_chain_valid):  Use lookup_misc_func.
1513	(Reported by Mark Peek <mark@imagen.com>.)
1514
1515	* solib.c (solib_map_sections):  Relocate all sections, even
1516	though only the text section's size is tracked.  Mark ld_text
1517	for eventual elimination as we generalize to N sections.
1518
1519	* infrun.c (wait_for_inferior):  Don't check if the PC is in a
1520	call_dummy if we were stopped by a random signal that is being
1521	passed to the program.  This produced wierd results when calling
1522	functions in the inferior and signals (e.g. SIGALRM) were in use.
1523
1524Tue Sep 24 18:05:30 1991  John Gilmore  (gnu at cygnus.com)
1525
1526	* infrun.c (IN_SIGTRAMP):  Not parenthesized properly.

1539
1540	GDB-4.1 release!
1541

1549	the language string to its current state (fix from A. Beers).
1550	* doc/gdbint.texinfo:  Roll in information from README.  Rearrange
1551	"how to install" and "how to print the doc" stuff so it drops
1552	easier into README.
1553	* configure.in:  Rename rtpc CPU to romp to match config.sub.
1554	* README, WHATS.NEW, TODO:  Update for gdb-4.1.

1562
1563Fri Sep 20 15:46:00 1991  Roland H. Pesch  (pesch at cygnus.com)
1564
1565	* doc/Makefile: generate aux version-no file doc/gdbVN.m4
1566	from main Makefile.in version definition

1572	doc by Andrew Beers
1573
1574Fri Sep 20 15:00:57 1991  Per Bothner  (bothner at cygnus.com)
1575
1576	* mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1577	compilers (which may lack stddef.h).
1578
1579Fri Sep 20 13:29:42 1991  John Gilmore  (gnu at cygnus.com)
1580
1581	* dbxread.c (read_dbx_symtab, process_one_symbol):  N_FN and
1582	N_WARNING are the same except for the N_EXT bit, so just use their
1583	values alone, rather than OR-ing them with N_EXT.
1584
1585Fri Sep 20 12:27:55 1991  Stu Grossman  (grossman at cygnus.com)
1586

1596	case we aren't debugging GDB.
1597	* language.c (_initialize_language):  Fix type check and range
1598	check documentation strings.
1599	* utils.c (!HAVE_VPRINTF):  Define vfprintf as a function, so
1600	language.c can use it.  (Though language.c should really not be
1601	handling warnings/errors the way it does, FIXME.)
1602	* symtab.c (lookup_primitive_type):  const lint.
1603
1604	Bugfix from Peter Schauer:
1605	* source.c (lines_to_list):  Make signed, to avoid comparison

1613	(gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1614	New rules for building distributions.  Normal distribution
1615	is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1616	one level up from here; it calls make-proto-gdb.dir to build a
1617	directory `proto-gdb' which is an image of the release.  The old
1618	`gdb.tar.Z' rule still works too.
1619	* config.sub, configure:  Roll in latest from ..
1620
1621Thu Sep 19 17:41:24 1991  Roland H. Pesch  (pesch at cygnus.com)
1622
1623	* doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1624	new-target, and new-config chapters; fix minor typos; come closer
1625	to usual GNU markup conventions for @file @samp @code @var.
1626
1627Thu Sep 19 17:04:12 1991  Per Bothner  (bothner at cygnus.com)
1628
1629	Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1630	* mipsread.c (parse_partial_symbols): Enter the name of all
1631	structs/unions... into the psymtab so we can access them if the
1632	symtab is not read in.

1745Tue Sep 17 08:37:41 1991  John Gilmore  (gnu at cygint.cygnus.com)
1746
1747	Add Andrew Beers' changes for Modula-2 support.  His ChangeLog
1748	entries are enclosed herein.  Not all of these changes
1749	have been merged into the master GDB sources -- check the
1750	ChangeLog above here for the merge log.
1751
1752Mon Jun  3 17:05:45 EDT 1991
1753
1754     m2-exp.y       Created.  Tested outside of GDB for a few days.  Proper
1755                    operators were added, C specific operators and tokens
1756                    removed.  yylex() revamped to some extent.  Still things
1757                    missing from the grammar, such as sets.
1758                    Tested for two weeks in GDB v3.5.
1759
1760Tue Jun 11 17:23:48 EDT 1991
1761
1762     m2-exp.y       Added boolean constants TRUE and FALSE to the grammar
1763                    so they are built-in.  Sort of a hack.
1764
1765Fri Jun 14 12:53:51 EDT 1991
1766
1767     m2-exp.y       Added range checking for numeric constants.  Any numeric
1768                    constant is assumed to be of builtin type INTEGER unless:
1769                    (1) it is octal or hexadecimal, in which case it is a
1770                    CARDINAL; (2) it is too big to fit into an INTEGER, in
1771                    which case it is a CARDINAL.
1772     eval.c         Added simple range checking for +, -, and * on integers.
1773                    Doesn't work very well for *, since 6 * 1,000,000,000 =
1774                    1,705,032,704, which fails the simple test of result >=
1775                    first_operand, no matter in what order the operands are.
1776
1777Tue Jun 18 14:11:30 EDT 1991
1778
1779     Broke the parser into parts, one containing the C grammar and the other
1780     containing code to be shared by all of the grammars.
1781
1782     The following files no longer exist:
1783
1784          expread.y
1785          expread.tab.c
1786
1787     The following files were added:
1788
1789          c-exp.y        (The C grammar)
1790          m2-exp.y       (The Modula-2 grammar)
1791          parser-code.c  (Code that is shared by the above grammar)
1792          parser-code.h
1793          parser-defs.h
1794
1795     Makefile.dist  Changed to reflect the above dependencies.  NOTE:  It is
1796                    now necessary to use the Bison compiler compiler, since it
1797                    will generate function/variable prefixes other than yy.
1798
1799Tue Jun 18 16:47:49 EDT 1991
1800
1801     symtab.[ch]    Added the external variable working_lang, than holds the
1802                    value of the current working language.
1803                    Added the ennumerated type language_mode, with the values
1804                    language_auto and language_manual, the former meaning that
1805                    GDB sets working_lang as needed, and the latter meaning
1806                    that the value of working_lang is totally under user
1807                    control.
1808     symtab.[ch]    Added the Modula-2 pervasive types INTEGER, CARDINAL,
1809                    REAL, BOOLEAN and CHAR.  Also added the type codes
1810                    TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1811     utils.c        Added set_language_command and show_language_command to
1812                    implement the GDB support commands "set language" and
1813                    "show language".
1814     expression.h   A number of identifiers were added to the type exp_opcode
1815                    to facilitate Modula-2 builtin functions, integer
1816                    division, and array indexing.
1817
1818Wed Jun 19 13:25:58 EDT 1991
1819
1820     language.h     Added the macro STRICT_TYPE, which evaluates to non-zero
1821                    if the language specified by working_lang requires the use
1822                    of strict typing of expressions.  Eventually, even this
1823                    will be able to be changed by the user.
1824                    Added the macro RANGE_CHECK, which evaluates to non-zero
1825                    if the language specified by working_lang requires the
1826                    checking of a value against the domain of its type.
1827                    Eventually, even this will be able to be changed by the
1828                    user.
1829     language.[ch]  Predicates involving types (simple_type, ordered_type,
1830                    same_type, integral_type, numeric_type, character_type,
1831                    boolean_type, float_type) are added.  These predicates are
1832                    based on the current value of working_lang, and are handy
1833                    in type-checking.
1834
1835Wed Jun 19 15:39:34 EDT 1991
1836
1837     eval.c         Added the function type_array_rank which computes the rank
1838                    of an array type.
1839     valarith.c     Added the funtion value_bool, which when given a integer
1840     value.h        value (ie. struct value *) as an argument, it returns a
1841                    boolean value (ie.  struct value *) true if that integer
1842                    is non-zero, and a boolean value false otherwise.
1843     valprint.c     Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1844                    will print out properly.
1845
1846Wed Jun 19 16:36:34 EDT 1991
1847
1848     valops.c       Added the function value_capitalize, which returns it
1849     value.h        argument capitalized if its argument is a lowercase
1850                    letter, or the argument unchanged if its argument is not a
1851                    letter.
1852     valarith.c     Added the function range_check_p, which returns non-zero
1853     value.h        if its value argument is between the integral bounds upper
1854                    and lower.
1855                    Added the function range_check_enum_p, which makes sure
1856                    that its value argument is a valid member of the domain of
1857                    its type argument.
1858                    Added the function range_check_range_p, which makes sure
1859                    its value argument lies between the upper and lower bounds
1860                    of its type argument, which must be a ranged type.
1861                    Added the function check_array_index, which range and type
1862                    checks an index of an array.
1863                    Added the function value_multi_subscript, which computes
1864                    array[idx1,idx2...idxN], given a value array and an array
1865                    of values representing indicies.
1866     values.c       Changed value_from_long to work with TYPE_CODE_CHAR and
1867                    unpack_long to work with TYPE_CODE_BOOL and
1868                    TYPE_CODE_CHAR.
1869
1870Wed Jun 19 18:04:08 EDT 1991
1871
1872     symtab.c       Stored pervasive types in a structure and make
1873                    lookup_pervasive_type() a lookup function that was based
1874                    on working_lang.  If lookup_pervasive_type() returned
1875                    non-zero, then that value was returned (a fix, since
1876                    before it simply wouldn't return the pervasive type.)
1877     language.h     Added the macro CAST_IS_CONVERSION, which evaluates to
1878                    non-zero if the language specified by working_lang means
1879                    "conversion" when it says "cast".
1880     valops.c       Added the function value_real_cast(), which performs a
1881     value.h        *cast*, not a *conversion*, which is what value_cast()
1882                    does when it can.  In particular,
1883                    value_cast(<float_type>,4) = 4.0, while
1884                    value_real_cast(<float_type>,4) = some mess.
1885     eval.c         Modula-2 builtin functions implemented:  ABS, CAP, CHR,
1886     parser-code.c  FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1887     expression.h   Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1888                    and MIN on integral types.  *NOTE*: These are currently
1889                    hardcoded to work only if there are 8 bits per storage
1890                    unit.  FIXME.
1891     eval.c         Made logical functions call value_bool to return a
1892                    properly typed boolean value, based on working_lang.
1893
1894Thu Jun 20 11:55:27 EDT 1991
1895
1896     valprint.c     Types now print out in a Modula-2 fashion.  This works for
1897                    the cases when the type is printed out step-by-step, that
1898                    is, it doesn't work when the name of a structured type
1899                    (which includes the keyword "struct", etc.)  is simply
1900                    displayed.
1901                    FIXME:  Perhaps this is bad.  Parts of it seem to kludgey,
1902                    since type specifications in C and Modula-2 are very
1903                    different.  The C printing of a type is very recursive,
1904                    whereas in Modula-2 it is generally very simple.  C has
1905                    type prefixes and suffixes, which have no real analogue in
1906                    Modula-2.  Maybe type_print() should call a language
1907                    specific type printer.  This is also advantageous if we
1908                    compile GDB to exclude some of the languages.  We'll just
1909                    leave those functions out.
1910
1911Thu Jun 20 16:57:10 EDT 1991
1912
1913     dbxread.c      When reading the complete symbol table in (via
1914                    psymtab_to_symtab()), the number and types of function
1915                    arguments are added to a function type.  define_symbol()
1916                    calls add_param_to_type() to accomplish this.
1917                    Assumption:  when we come across a function definition
1918                    (N_FUN symbol with an 'f' or 'F' in the name), its
1919                    arguments will appear before another function definition.
1920                    When a function is found, a pointer to its type is placed
1921                    in the global in_function_type.  Changes that
1922                    add_param_to_type() makes are to this global.
1923     valprint.c     The type of a function now includes (for Modula-2) the
1924                    types of its parameters.
1925     eval.c         Type checking and a check for the proper number of
1926                    arguments is now done for function calls.  Not sure of the
1927                    impact this has on C++ member function yet.
1928
1929Thu Jun 20 19:58:48 EDT 1991
1930
1931     valprint.c     Rewrote the type printer.  Broke it into two language
1932                    specific parts, adding the functions type_print_m2() and
1933                    type_print_m2_1().
1934                    An unfortunate consequence is this:  if you debugging a C
1935                    program in Modula-2 mode (why?), info types does not work
1936                    well with regular expressions, since the types are printed
1937                    out in Modula-2 terminology, but stored in C terminology.
1938     language.[ch]  Added the functions new_type_last(), type_keyword(), and
1939                    type_sep() to aid in the printing of typedefs.
1940     symtab.c       Made the printing of typedefs as language independent as
1941                    possible through calls to new_type_last(), type_keyword(),
1942                    and type_sep().
1943
1944Fri Jun 21 11:50:26 EDT 1991
1945
1946     dbxread.c      Check all incoming ennumerated types.  If it looks like
1947                    Modula-2's BOOLEAN type, then change the type_code of the
1948                    type to TYPE_CODE_BOOL so we can process it as a boolean
1949                    variable.
1950     valprint.c     Replaced some of the 0x%x with calls to sprintf and
1951                    hexformat() in val_print().
1952     language.[ch]  Added the function hex_to_string(), which converts its
1953                    integral argument to a hexadecimal number (format is
1954                    language based) and returns the result as a string.
1955
1956Mon Jun 24 12:25:07 EDT 1991
1957
1958     valprint.c     Some functions call type_print_1() directly, instead of
1959     value.h        using type_print(), so they can specify where (column) to
1960                    print things.  Since type_print() takes care of language
1961                    dependence, that needs to be called first.  Added a
1962                    parameter depth to type_print() (so it is now like
1963                    type_print_1).  Changed type_print to type_print_at, and
1964                    made type_print a macro that passes a depth argument of
1965                    zero.
1966     symmisc.c      Changed all calls to type_print_1 to calls to
1967                    type_print_at.
1968     Makefile.dist  Made it possible to build GDB for a specific set of
1969     depend         languages.  Do this by passing a definition for the macro
1970                    LANGS to make.  LANGS should be a string containing a
1971                    space-separated list of language names (ie. LANGS="c m2").
1972                    The default is to build all languages.  Note that grammar
1973                    files must follow the naming convention of <lang>-exp.y.
1974     gdb.lang       This holds the current value of the LANGS macro.  It is
1975                    examined every time make is called, and is updated if
1976                    necessary.
1977     eval.c         Added #ifdef _LANG_<lang> to these files.
1978     expread.c      Still need to add them to dbxread.c and coffread.c.
1979     main.c
1980     source.c
1981     symtab.c
1982     utils.c
1983     valarith.c
1984     valprint.c
1985
1986Mon Jun 24 16:33:11 EDT 1991
1987
1988     language.[ch]  Added the functions hexformat_pre() and
1989                    hex_to_string_pre(), which take a prefix argument to
1990                    include in the format string.  Thus, hexformat_pre("08") will
1991                    return "0x08x" (if the working language is language_c).
1992                    Made hexformat() and hex_to_string() calls to the above
1993                    with "" as the prefix argument.
1994
1995     am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1996     dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1997     infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1998     mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1999     pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
2000     stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
2001     valprint.c, vax-pinsn.c
2002
2003          Changed all occurences of 0x%[0-9]*l*x in printf format strings to
2004          calls to hexformat() and hex_to_string().  Format strings without
2005          the leading "0x" were ignored.
2006
2007     depend         Updated to take the above into account.
2008
2009
2010Tue Jun 25 15:27:18 EDT 1991
2011
2012     symtab.h       Added the types range_mode_t, range_check_t, type_mode_t,
2013                    and type_check_t to keep track of the current state of
2014                    range and type checking.
2015     main.c         Added the variables range_mode, range_check, type_mode,
2016                    and type_check to record the current state of range and
2017                    type checking.  Added initialization code to main().
2018     language.h     Changed the macros STRICT_TYPE and RANGE_CHECK to examine
2019                    the above variables.
2020
2021
2022Tue Jun 25 17:57:08 EDT 1991
2023
2024     dbxread.c      process_one_symbol() updates the variable (enum language)
2025                    source_lang based on the extension of the filename
2026                    contained in the N_SO sybmol that started this symtab.
2027                    When end_symtab() is called, the value of source_lang is
2028                    put into the language field.
2029     stack.c        select_frame() sets working_lang (and possibly type_check
2030                    and range_check) to the language field of the symtab
2031                    associated with the frame that is selected if working_mode
2032                    is language_auto.  If working_mode is language_manual, a
2033                    warning is printed and working_lang is not set.
2034     language.c     Added the function set_type_range(), which sets the value of
2035                    type_check and range_check (if their modes call for
2036                    automatic setting) based on the current value of
2037                    working_lang.  A non-zero argument will cause the current
2038                    settings to be output.
2039
2040
2041Wed Jun 26 14:51:40 EDT 1991
2042
2043     eval.c         Added range checks on assignment.
2044     m2-exp.y       Added the grammar for sets to the language.  Currently,
2045                    these do not do anything except print an error message.
2046
2047Wed Jun 26 17:01:04 EDT 1991
2048
2049     m2-exp.y       Added the ability for parse_number() to parse negative
2050                    numbers.  A global flag is set upon encountering a unary
2051                    minus.  This was done to make, for example, 1 parse as a
2052                    CARDINAL, and not as an integer, per Wirth's examples in
2053                    Programming in Modula-2 ed.4.
2054     valprint.c     Added support for "set radix 2" by then setting
2055                    output_format to 't'.
2056     eval.c         Implemented range checking on subrange types.  Added calls
2057                    to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
2058                    Implemented MIN and MAX for ennumerated types.  The
2059                    minimum value of an ennumerated type is defined by Wirth
2060                    as the first identifier, and the maximum as the last.
2061     m2-exp.y       Made octal numbers ending with "B" be characters and those
2062                    ending with "C" be numbers, per Wirth's book. (p. 34)
2063
2064Thu Jun 27 14:11:52 EDT 1991
2065
2066     stack.c        select_frame() now only sets working_lang, it does not
2067                    notify the user.  If working_mode is language_manual, then
2068                    a warning is issued once.
2069     main.c         At the end of each call to execute_command(), working_lang
2070                    is checked against the local static (enum language)
2071                    current.  If they differ and working_mode is
2072                    language_auto, the new settings of language, type and
2073                    range checking are printed out.
2074     stack.c        Modified frame_info() to include the language of the
2075                    current frame in the output of "info frame".
2076     language.[ch]  Added the function language_str() which returns the name
2077                    of the current language.
2078
2079Fri Jun 28 15:33:14 EDT 1991
2080
2081     m2-exp.y       Added the built-in procedures INC, INCL, DEC, and DECL to
2082                    the language.  INCL and DECL currently cause an error,
2083                    since sets are not implemented yet.  INC and DEC are
2084                    implemented as PREINCREMENT/PREDECREMENT with one
2085                    argument, and as ASSIGN_MODIFY with two arguments.
2086     eval.c         Added type checking to the above cases.
2087     value.h        Added not_lval_constant to the lval_type ennumerated type.
2088                    not_lval_constant means that the value is a constant
2089                    value; that is 3 or 'a' or TRUE, not as in a constant
2090                    identifier.  This is used to help coerce numbers such as 3
2091                    to either signed or unsigned numbers.
2092     valops.c       Added the function value_coerce_constants() which coerces
2093                    constant integers as following:  if one is a constant and
2094                    the other is not, the constant's type is set to the type
2095                    of the other argument.  If both are constants and one is
2096                    signed, the other is converted to a signed constant.
2097
2098Sat Jun 29 17:26:29 EDT 1991
2099
2100     valarith.c     Added a better range checker.  It now checks range
2101                    (successfully) on integral operations [+-] (signed and
2102                    unsigned) for any C sized type.  Still does not work well
2103                    for multiplication.)
2104                    int_in_size() returns an integer that is coerced to fit into
2105                    specified number of bytes.
2106
2107Mon Jul  1 13:04:14 EDT 1991
2108
2109     language.[ch]  Added the function binop_result_type(), which returns the
2110                    builtin (struct type *) type that would be the result of a
2111                    binop on the two values V1 and V2.
2112
2113Wed Jul  3 19:22:53 EDT 1991
2114
2115     source.c       Extended source_info() to include the source language in
2116                    the output from "info source".
2117
2118Fri Jul  5 13:48:52 EDT 1991
2119
2120     utils.c        Moved the support functions for the GDB set/show commands
2121                    dealing with language into language.c.
2122     language.c     Added the function language_info(), which displays info
2123                    about the current working language, type and range check
2124                    settings.  Called via the GDB command "info language".
2125                    Added an initialization routine _initialize_language(),
2126                    that sets defaults for the language, type and range
2127                    variables and sets up the new GDB commands.
2128     main.c         Language setup moved to language.c.
2129     depend         Rebuilt.
2130
2131Mon Jul  8 10:10:22 EDT 1991
2132
2133     valarith.c     Debugged the range checker for arithmetic.  Still does not
2134                    work for multiplication very well.
2135
2136Mon Jul  8 12:40:37 EDT 1991
2137
2138     language.[ch]  Added the function value_true() which returns non-zero if
2139                    its argument represents a boolean true value.
2140     breakpoint.c   Changed breakpoint_cond_eval() to call value_true() to
2141                    check the truth of an expression.
2142
2143Thu Jul 11 12:51:34 EDT 1991
2144
2145     language.[ch]  Added the predicate structured_type(), which returns
2146                    non-zero if the argument is a structured type.
2147                    Added the predicate pointer_type(), which returns non-zero
2148                    if the argument is a pointer type.
2149     eval.c         Added the ability to do addition and substraction on
2150                    pointers and integers.   This case simply bypasses the
2151                    type checker.
2152
2153Thu Jul 11 14:41:42 EDT 1991
2154
2155     include/stab.def
2156                    Added the symbol N_DEFD (0x4a) which is a definition
2157                    module dependency that is used by the GNU Modula-2
2158                    compiler and the linker.  It is not important to GDB,
2159                    except that [dbx|coff|mips]read.c should ignore these
2160                    symbols.
2161
2162Fri Jul 12 16:07:00 EDT 1991
2163
2164     valprint.c     Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
2165                    0 in val_print().  Also added statements to the else part
2166                    to coerce type (argument to val_print) to a pointer type
2167                    if it is an "array of unspecified length".
2168     valops.c       Added the function value_m2_string(), which returns a
2169                    (value) value which is a constant string, whose type is
2170                    (ARRAY [0..n] OF CHAR).  The length field of the type
2171                    structure is set to zero, so it will be interpreted as an
2172                    "array of unspecified length".
2173     stack.c        Moved the language/frame mismatch check to
2174                    main.c:execute_command().
2175     main.c         The working language is recorded each time
2176                    execute_command() is executed.  If working lang has
2177                    changed during its execution, then the new
2178                    language/type/range info is printed out for the user.  If
2179                    the working language does not match the language of the
2180                    frame, a warning is issued.
2181
2182Sat Jul 13 16:16:39 EDT 1991
2183
2184     eval.c         Moved all the type-checking stuff for operators to
2185     language.[ch]  language.c.  This is so we can keep language-specific
2186                    stuff (like for what type operators are defined) in
2187                    language.c.
2188     language.[ch]  Added the function binop_type_check(), which checks to see
2189                    if its two (value) arguments are type-compatible with its
2190                    opcode argument.  The opcode should represent an operation
2191                    involving an operator.  Also added the macro function
2192                    unop_type_check, which calls binop_type_check with a
2193                    NULL second argument.
2194     expprint.c     Added Modula-2 operators to the op_print_tab, so info
2195     expression.h   break works correctly.  Also added "op_string", which
2196                    returns the string corresponding to the (enum exp_opcode)
2197                    opcode that is its argument.

2201
2202     coffread.c     Added code to record the type of function arguments with
2203                    each paricular function.  Code is very similar to that
2204                    added to dbxread.c.
2205     dbxread.c      Moved add_param_to_type() to symtab.c
2206     symtab.[ch]    Added function add_param_to_type() from dbxread.c
2207
2208     *** NOTE:  The above additions have not been tested.
2209
2210Mon Jul 15 12:50:47 EDT 1991
2211
2212     langauge.[ch]  Added the functions type_error and range_error, which work
2213                    like error() except if the type/range mode is set to
2214                    *_mode_warn, then they do not do a return_to_top_level(),
2215                    but merely print a warning.
2216                    Also changed [set|show]_[type|range]_command() to support
2217                    the new "warn" feature.
2218
2219Thu Jul 18 17:50:54 EDT 1991
2220
2221     mipsread.c     Added code to record the type of function arguments with
2222                    each particular function.  Code is very similar to that
2223                    added to dbxread.c.
2224
2225     *** NOTE:  The above additions have not been tested.
2226
2227Fri Jul 19 11:19:10 EDT 1991
2228
2229     defs.h         Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
2230                    UMIN_OF_SIZE, which when given a size of a numeric type,
2231                    return the maximum and minimum value it can hold.  UMAX...
2232                    and UMIN... return the result for unsigned types.
2233     symtab.h       Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
2234                    struct types.  They call above macros.
2235     dbxread.c      Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
2236                    avoid a name conlict with the above.
2237     c-exp.y        Added range checking on numeric constants in
2238                    parse_number() for completeness.
2239     valarith.c     Made binop_user_defined_p() and unop_user_defined_p()
2240                    return 0 if working_lang is not language_c.
2241
2242Thu Aug  8 14:17:22 EDT 1991
2243
2244	main.c
2245	printcmd.c
2246	breakpoint.c	Documentation strings of some commands changed to
2247				eliminate the references to the C language where
2248				appropriate.
2249
2250Tue Aug 13 15:48:03 EDT 1991
2251
2252	m2-exp.y		Added qualified identifiers to the grammar.  The semantics
2253				are slightly different from those of the GDB operator ::
2254	c-exp.y
2255	m2-exp.y		Added a rule to each grammar of the form:  start ::= exp |
2256				type_exp, where type_exp is any valid type expression.
2257	expression.h
2258	eval.c		Added the opcode OP_TYPE, and an error case in eval.c.
2259	printcmd.c	Modified ptype_command() so it actually parses the input
2260				(necessary for type expressions with scope qualifiers).
2261				Added the function ptype_eval() which expects an
2262				expression composed of one OP_TYPE element.
2263	*.[ch]		Replaced all occurences of parse_c_expression with
2264				parse_expression
2265	*.[ch]		Replaced all occurences of parse_c_1 with parse_exp_1
2266
2267[End of ChangeLog entries from Andrew Beers for Modula-2 support.]

2269Mon Sep 16 17:19:46 1991  John Gilmore  (gnu at cygnus.com)
2270
2271	Small fixes from Peter Schauer:
2272
2273	* infrun.c (child_attach):  Lint.
2274	* solib.c (find_solib):  Handle shared libs version 2.
2275
2276	Small fixes from David Wood:
2277
2278	* xm-ultra3.h (SYS_SIGLIST_MISSING):  Typo.
2279
2280	Small fixes:
2281
2282	* remote-vx.c:  Move <stdio.h> to top, for FILE.  Fix from
2283	John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
2284
2285	* utils.c (wrap_here):  Avoid wrap action of fputs_filtered if
2286	chars_per_line is at maximum (user typed `set width 0').  Fix
2287	from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
2288
2289Tue Sep 17 17:31:04 1991  Stu Grossman  (grossman at cygnus.com)
2290
2291	* coredep.c:  include ptrace.h where necessary.
2292	* mipsread.c(parse_lines):  fix unsigned char problem that was
2293	messing up line numbers on SGI's and possibly other MIPS based
2294	platforms.
2295	* infrun.c (child_create_inferior):  use better test to check
2296	return val from setpgrp().
2297	* tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3:  add these
2298	for sgi/irix support.
2299
2300Wed Sep 18 04:33:31 1991  Per Bothner  (bothner at cygnus.com)
2301
2302	* mipsread.c (parse_symbol):  Put non-static procedures
2303	in the global block.
2304
2305Fri Sep 13 00:14:52 1991  John Gilmore  (gnu at cygnus.com)
2306
2307	Patch together `text_start' and `text_end' for 29K port.
2308
2309	* exec.c (exec_command):  If NEED_TEXT_START_END, define the
2310	variables and set them based on the exec file.
2311	* am29k-tdep.c:  declare text_start.
2312	* valops.c (call_function_by_hand):  declare text_end.
2313
2314	* inferior.h:  Eliminate CANNOT_EXECUTE_STACK in favor of
2315	defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END.  This is
2316	because machines that do this will also have to know to
2317	set NEED_TEXT_START_END.  Besides, it was a redundant way to
2318	say the same thing.
2319	* tm-29k.h, tm-convex.h, tm-np1.h:  Eliminate
2320	CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
2321	NEED_TEXT_START_END.
2322
2323Thu Sep 12 00:22:24 1991  John Gilmore  (gnu at cygint.cygnus.com)
2324
2325	AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
2326
2327	* Makefile.in (CLIBS):  Put XM_CLIBS and TM_CLIBS at end.
2328	Pass MUNCH_DEFINE to munch whenever we run it.
2329	* am29k-pinsn.c (print_insn):  Handle NOP specially.  Avoid %#x
2330	format string; use 0x%x instead.
2331	* am29k-tdep.c:  Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
2332	* ultra-xdep.c, xm-ultra.h:  New files for Ultracomputer host system.
2333	* xm-rtbsd.h:  New host support for RT/PC running BSD Unix.
2334	* inflow.c:  Handle `short' process group IDs.
2335	* infptrace.c (fetch_register):  Support CANNOT_FETCH_REGISTER,
2336	and check for ptrace errors.
2337	* coffread.c (SDB_REG_TO_REGNUM):  Define if not already.
2338	(coff_symfile_init):  Initialize text_bfd_scnum.
2339	(read_coff_symtab):  Use it to find the text [and absolute?] sections.
2340	* ../config.sub:  Add vendor nyu and os "sym[1-9]*".
2341	* configure.in: Add hosts rtpc-*-* and a29k-*-*.
2342	Merge target arm case with other "easy" cases.  Add target
2343	cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
2344	Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
2345	process).
2346	* minimon.h, remote-adapt.c, remote-mm.c:  Add.
2347	* munch:  Cope with RT/PC putting fns in data segment.
2348	Restore ability to override `nm' by specifying MUNCH_NM.
2349	* xconfig/rtbsd, xconfig/ultra3:  New host systems.
2350	* tconfig/a29k:  Rename from tconfig/am29k.  Add remote-mm
2351	and remote-adapt.  Remove encapsulated coff #define's (the
2352	support should go in BFD, and gdb shouldn't know or care).
2353	* tconfig/a29k-kern:  Same, but for remote kernel debugging.
2354	* tconfig/ultra3:  For debugging user processes on Ultra3/Sym1.
2355	* tm-29k.h:  Update BADMAG (though it should go away).
2356	Allow the register definitions to be overridden in another
2357	tm-file.  Fix SR_REGNUM.  Add a mess of _REGNUM's.  Separate
2358	RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
2359	DUMMY_SAVE_GR96, for handling kernel calling conventions
2360	that use GR64+ rather than GR96+.
2361	* tm-ultra3.h:  New file, for use on Ultra3 Unix as well as for
2362	remote debugging of Ultra3 kernel.  Includes tm-29k.h and
2363	overrides various things.
2364
2365	* remote-mm.c (mm_attach, mm_wait):  Handle attach like
2366	child_attach does, making a clean stop in the newly attached
2367	program.
2368	* remote-eb.c:  Lint.
2369
2370	* coffread.c:  Make coffread independent of any particular
2371	variant of COFF.  Avoid #include-ing any particular one except
2372	internalcoff.h.  BFD now passes key values for symbol reading
2373	as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
2374	and the symbol masks and shifts); use them.
2375	Remove obsolete end_of_text_addr.
2376
2377	* exec.c:  Remove unused include files.
2378
2379Wed Sep 11 19:38:44 1991  John Gilmore  (gnu at cygint.cygnus.com)
2380
2381	* Makefile.in (documentation targets):  Pass $(M4).
2382	Bugfix from eggert@twinsun.com (Paul Eggert).
2383
2384	* stack.c (down_silently_command):  Check for stack existence.
2385

2389
2390Tue Sep 10 09:19:29 1991  John Gilmore  (gnu at cygint.cygnus.com)
2391
2392	* core.c (core_file_command):  Print frame at coredump with
2393	its level number, by calling print_stack_frame.
2394	* frame.h:  Add selected_frame_level, print_stack_frame.
2395	* frame.h, stack.c:  Remove print_sel_frame, print_selected_frame.
2396	* convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
2397	Change print_sel_frame and print_selected_frame callers to
2398	print_stack_frame.
2399
2400	* dbxread.c (read_ofile_symtab):  Avoid empty else clause.
2401	* symfile.c (free_named_symtabs):  Ditto.
2402	* main.c (main):  wrap_here needs an arg.
2403	* solib.c (find_solib):  Avoid memory access if _DYNAMIC is zero.
2404	(solib_add):  Avoid noise.
2405	(solib_create_inferior_hook):  Lint.
2406	(sharedlibrary_command):  Move dont_repeat to here.
2407	* utils.c (error):  Call wrap_here to force buffered output.
2408
2409	Small patches from Peter Schauer:
2410
2411	* coffread.c (start_symtab):  Free any existing line_vector before
2412	malloc-ing new one.
2413	(read_coff_symtab):  Ditto for type_vector.
2414
2415	* source.c (lines_to_list):  New variable, replacing function.
2416	(all uses):  Use as variable.
2417	(_initialize_source):  Add 'set listsize' and 'show listsize'.
2418	* utils.c (lines_to_list):  Remove function.
2419	* stack.c (print_frame_info):  Use as variable.
2420	* defs.h (lines_to_list):  Remove declaration.
2421
2422Mon Sep  9 13:45:57 1991  John Gilmore  (gnu at cygint.cygnus.com)
2423
2424	* breakpoint.c (insert_breakpoints):  Restore warning about
2425	the program might be running in another process, but only for
2426	systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
2427	* xm-hp300bsd.h, xm-mips.h, xm-vax.h:  Define it.
2428
2429	* utils.c (error):  if error_pre_print is set, print the string
2430	first.
2431	* main.c (main, print_gnu_advertisement, print_gdb_version):
2432	Reformat legalese so it always prints, but acts as an "I'm here"
2433	message while symbols are being read.  If any errors occur,
2434	print a few newlines to set off the message and start it at the
2435	left margin.  Remove mention of "help" command, and don't yak
2436	about symbol reading.
2437	(catch_errors):  Error string is now printed first in case of
2438	error, not last.
2439	* command.c (undef_cmd_error, lookup_cmd):  On undefined command,
2440	suggest the "help" command.
2441
2442	* Makefile.in (VERSION):  Set to 4.0.2.
2443
2444Thu Sep  5 23:49:48 1991  John Gilmore  (gnu at cygint.cygnus.com)
2445
2446	* .gdbinit:  Remove useless "rr" command.  Set complaints
2447	to 1 for people debugging gdb.
2448
2449	* breakpoint.c, remote-vx.c:  Reword strings printed by
2450	catch_errors callers.
2451
2452Wed Sep  4 11:07:50 1991  John Gilmore  (gnu at cygint.cygnus.com)
2453
2454	* WHATS.NEW:  "history write -> history save".  Doc "write on/off".
2455	(Fix from kenc@viewlogic.com.)
2456
2457	Fix some infrastructure to be able to cope with host and target
2458	machines with different sized basic types (ints, ptrs, etc).
2459	(Idea from pierre@la.tce.com (Pierre Willard).)
2460
2461	* values.c (value_from_longest):  Rename from value_from_long.
2462	Handle pointer types as well as integers, so that targets with
2463	different pointer sizes from the host can be accomodated.
2464	* breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
2465	valarith.c, valops.c, valprint.c, value.h, values.c:  Rename
2466	uses of value_from_long to value_from_longest.
2467	* eval.c, findvar.c, printcmd.c, valarith.c, valops.c:  Pass
2468	the correct pointer type to value_from_long{est}.
2469
2470	* doc/gdb.texinfo ($_, $__):  Describe types of these variables.
2471
2472	* remote-vx.c:  Remove obsolete code for calling functions via
2473	vxworks kludge interface (it referenced value_from_long).
2474
2475	* valops.c (value_string):  Find malloc with lookup_misc_func, not
2476	raw search.
2477
2478Tue Sep  3 18:37:46 1991  John Gilmore  (gnu at cygint.cygnus.com)
2479
2480	Make writing to files work properly.  (Fixes to BFD are also needed.)
2481
2482	* core.c (core_open):  Open file ourselves, read or r/w, depending on
2483	write_files.  Use bfd_fdopenr.
2484	* gdbcore.h (write_files):  New variable.
2485	* exec.c (write_files):  Define variable, add set&show for it.
2486	(exec_file_command):  Use write_files to open for read or r/write.

2489	are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
2490
2491	* inferior.h (stop_soon_quietly):  Add to exported variables.
2492	* infrun.c (child_create_inferior):  call solib hook, if defined.
2493	(child_attach):  call solib hook, if defined.
2494	* solib.c:  Include inferior.h.  Add from_tty to so_list as kludge.
2495	(find_solib):  Use lookup_misc_func rather than hand-rolled.
2496	(symbol_add_stub):  New stub for catch_errors.
2497	(solib_add):  Avoid output if !from_tty.  Catch errors rather
2498	than just calling symbol_file_add and bombing.
2499	(solib_create_inferior_hook):  Interface with the target process
2500	to let it read and alloc shared libs, then figure out what it did.
2501
2502	* core.c (validate_files):  Fix typo, soften warning.
2503	(Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)

2506	demangling is off.  (Fix from J.T. Conklin <jtc@cayenne.com>.)
2507
2508	* infrun.c (proceed):  Cast -1 to (CORE_ADDR) before comparing.
2509	(Fix from pierre@la.tce.com (Pierre Willard).)
2510
2511	* main.c (catch_errors):  Change argument to a char * from an int,
2512	since a char * can point to a struct full of glop, but an int
2513	is not guaranteed to be able to hold a pointer.
2514	* breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
2515	breakpoint_re_set_one, breakpoint_re_set):  Adapt.
2516	* core.c (core_open, solib_add_stub):  Adapt.
2517	* remote-vx.c (symbol_stub, add_symbol_stub, callers):  Adapt.
2518
2519Wed Aug 28 18:18:05 1991  John Gilmore  (gnu at cygint.cygnus.com)

2581Thu Aug 22 02:02:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
2582
2583	Install new configuration scheme for GDB and friends.
2584
2585	* config.sub:  Translate ordinary names to three-part names.
2586	* configure:  Use three-part names internally.
2587	* configure.in:  Translate three-part names to filenames.
2588
2589	* README, WHATS.NEW:  Update for gdb-4.0.
2590	* Makefile.in:  Roll VERSION to 3.99.
2591
2592Wed Aug 21 18:21:09 1991  John Gilmore  (gnu at cygint.cygnus.com)
2593
2594	* infptrace.c (KERNEL_U_ADDR_BSD):  Include a.out.gnu.h.
2595	* i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2596	tm-m68k.h, remote-nindy.c:  Change ext_format_XXX structs
2597	to single structures rather than arrays; when passing
2598	their address, use &.  This avoids trouble with bdead compilers.
2599	* mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2600	instead.  This avoids portability headaches.
2601	* mips-tdep.c (mips_do_registers_info):  Only print FP regs if
2602	asked to.
2603	* source.c (open_source_file):  Avoid ANSI const bdeath by
2604	skipping declaration and then casting result value.
2605	* tm-hp300bsd.h:  Clarify comment.
2606	* utils.c (strstr):  Result is const char *; ANSI bdeath.
2607	* xm-hp300bsd.h:  Define HOST_BYTE_ORDER.  Redefine INT_MIN,
2608	since system include file defines it differently from "defs.h",
2609	though the two are equivalent for our purposes.
2610	* tconfig/hp300bsd:  Add m68k-tdep.o.
2611
2612Tue Aug 20 16:01:11 1991  John Gilmore  (gnu at cygint.cygnus.com)
2613
2614	* tconfig/sun*4:  Remove warnings about system assembler.
2615
2616Mon Aug 19 13:44:46 1991  John Gilmore  (gnu at cygint.cygnus.com)
2617
2618	* mcheck.c:  Avoid warning about undeclared abort fn.
2619	* tm-sparc.h (PC_ADJUST):  Avoid calling error() from this;
2620	it causes recursive calls to error() when used in cleanups.
2621	To do so requires that we make it a function, so we do.
2622	* sparc-tdep.c (sparc_pc_adjust):  New implem of PC_ADJUST.
2623	* utils.c (do_cleanups):  Remove the current cleanup from the
2624	chain *before* calling it, in case error() is called from it.
2625	The result won't be pretty, but won't be an infinite loop either.
2626
2627Mon Aug 19 00:41:04 1991  Michael Tiemann  (tiemann at cygint.cygnus.com)
2628
2629	* dbxread.c (read_struct_type): Grok anon structs for C++.
2630	(vb_name, vptr_name): Null terminate these strings.
2631
2632Fri Aug 16 08:31:03 1991  John Gilmore  (gnu at cygint.cygnus.com)
2633
2634	Minor bug fixes from BSD Net2 gdb:
2635
2636	* blockframe.c (get_prev_frame_info):  If FRAME_CHAIN_COMBINE
2637	returns 0, there is no previous frame.
2638	* breakpoint.c (commands_command):  If !from_tty, don't call
2639	input_from_terminal_p().
2640	* dbxread.c (record_misc_function):  Speed up slightly.
2641	(compare_psymbols):  Ditto.
2642	* infcmd.c (do_registers_info):  Take a second argument to
2643	determine whether to print float registers.  "info registers"
2644	does not do so anymore.  "info all-registers" does, now.
2645	* mips-tdep.c, pyr-tdep.c (xxx_do_registers_info):  Take second
2646	arg and ignore it.
2647	* tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO):  Pass second arg.
2648	* inflow.c (initialize_inflow):  Set tflags_ours correctly.
2649
2650	Other fixes:
2651
2652	* breakpoint.c (bpstat_do_actions):  Use a cleanup to restore
2653	executing_breakpoint_commands if we are interrupted by error.
2654	* coffread.c (init_lineno):  Avoid problem with zero-sized linetab
2655	versus malloc/free.  From: john@labtam.labtam.oz.au (John Carey).
2656	* core.c (solib_add_stub, core_open):  Call SOLIB_ADD inside a
2657	catch_errors() so we can setup the frame regardless of whether
2658	the shared libs work.
2659	* ieee-float.c (double_to_ieee_extended):  Get exponent from
2660	right place in little-endian systems.  From John Carey.
2661
2662Thu Aug 15 18:43:57 1991  John Gilmore  (gnu at cygint.cygnus.com)
2663
2664	* main.c: Remove unused terminating_signals and catch_termination().
2665	(long_options):  Terminate with a zero element.
2666	[Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2667	(gdb_readline):  Make call-compatible with readline.
2668	(init_signals):  Improve comments re vfork vs. signal.
2669
2670	* utils.c (prompt_for_continue):  Use new gdb_readline().
2671	If we prompt for continuation, we don't let CR repeat the previous
2672	command, once we get back to a prompt.  It's too easy to keep
2673	hitting CR, expecting "--more--" prompts, and have some long
2674	command start repeating on you.
2675
2676Tue Aug 13 16:17:56 1991  John Gilmore  (gnu at cygint.cygnus.com)
2677
2678	* blockframe.c (frameless_look_for_prologue):  Speed up by
2679	calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2680	* tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2681	Define two variants, one faster.
2682	* sparc-tdep.c (sparc_frame_chain):  Use target_read_memory
2683	and return zero, rather than giving an error.
2684	(setup_arbitrary_frame):  Initialize the PC in the new frame.
2685	(skip_prologue):  Add a second arg saying whether we're just
2686	checking for a frameless function or not.
2687
2688	* core.c (core_open, core_close, core_xfer_memory):  Move
2689	section table pointers and bfd* into the target_ops.
2690	(core_open):  Allow errors in shared lib reading, etc.
2691	(core_files_info):  Describe shared library sections.
2692
2693	* exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2694	exec_files_info, set_section_command):  Move section table
2695	pointers and bfd* into the target_ops.
2696	(add_to_section_table):  Add BFD to section table.
2697
2698	* target.c (target_xfer_memory, target_info):  Pass target to
2699	xfer_memory and target_info functions.
2700	* target.h:   ''
2701
2702	* gdbcore.h:  Move struct section_table.
2703	* target.h:  New home of struct section_table.
2704
2705	* solib.c (solib_add):  New argument is the target_ops whose
2706	section list is to be added to, if any.  Reallocate the
2707	sections in that target to add any that come from shared libs.
2708	(throughout) so_sections renamed to sections.
2709	(solib_xfer_memory):  Deleted.
2710	* tm-sunos.h (SOLIB_ADD):  Add target argument.
2711	(SOLIB_XFER_MEMORY):  Delete.
2712
2713	* core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2714	remote-vx.c, remote.c, target.c, target.h:  Remove add_syms vector
2715	from target_ops.  It's the same on all targets.  Add two section
2716	pointers to target_ops.
2717
2718	* stack.c (find_relative_frame):  Dump ancient algorithm for
2719	"down", just use handy "next" pointers.
2720	(frame_command):  Don't error if there is no stack; let user
2721	set one.
2722
2723	* inflow.c (new_tty_prefork, new_tty):  New prefork routine
2724	modifies static state in the parent process; new_tty itself
2725	runs in the child and modifies the child's file descriptors
2726	to match the saved static state.
2727	* infrun.c (child_create_inferior):  Call new_tty_prefork,
2728	fork, then new_tty.
2729
2730	* infptrace.c (child_xfer_memory):  Add ignored target arg.
2731	* remote-eb.c (eb_xfer_inferior_memory):  ''
2732	* remote-nindy.c (nindy_xfer_inferior_memory):  ''
2733	* remote-vx.c (vx_xfer_memory):    ''
2734	* remote.c (remote_xfer_memory):   ''.  Rename from
2735	remote_xfer_inferior_memory.
2736
2737	* main.c (main):  Only try to attach "corefile" argument if
2738	it starts with a digit.
2739
2740	* symfile.c (symbol_reloading):  New "set/show" variable.
2741	(symbol_file_add):  Shorten message about symbol reading.
2742	(add_symbol_file_command):  Merge with add_syms_addr_command,
2743	since this should work on all targets now.
2744	(stop_whining):  Default to zero, to shut up complaints
2745	about bad symbol tables on many systems.
2746	(free_named_symtabs):  Just exit unless symbol_reloading.
2747
2748	* xm-sun3os4.h, xm-sun4os4.h:  Define BROKEN_LARGE_ALLOCA,
2749	and add comment explaining shared library screw.
2750
2751	* source.c:  #if defined => #ifdef.
2752
2753Thu Aug  8 12:23:19 1991  John Gilmore  (gnu at cygint.cygnus.com)
2754
2755	* doc/gdbint.texinfo:  Improve doc on porting to new OS's.
2756
2757Tue Aug  6 17:16:15 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
2758
2759	* doc/rdl-apps.texinfo: provide default readline-appendix finder
2760	(doc/Makefile knows how to make one for local config)
2761
2762	* Makefile.in: use doc/Makefile for doc targets
2763
2764	* doc/Makefile: GDB documentation now has its own Makefile
2765	  doc/refcard.tex: renamed from "gdbrc.tex"
2766	  doc/gdbint.texinfo: add markup in "Cleanups" chapter
2767
2768
2769Fri Aug  2 00:13:06 1991  John Gilmore  (gnu at cygint.cygnus.com)
2770
2771	* values.c (baseclass_addr):  When reading target memory, use the
2772	length of the basetype, not the upper type.  We've only malloc'd
2773	enough space for the basetype, leading to errors in free().
2774
2775	* expprint.c (print_subexp):  Print UNOP_MEMVAL of an OP_LONG that
2776	ends up as a function specially, since we know the actual type of
2777	the pointed-to address.  This (somewhat) fixes display of
2778	expressions that include misc_function_vector names.  Try `cond 1
2779	!strcmp("a","b")' then `i b'.
2780
2781	* infrun.c:  Move DO_DEFERRED_STORES from proceed() to resume().
2782	The child can be proceeded from inside wait_for_inferior in
2783	evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2784	getting skipped in that case.
2785
2786	* expprint.c (print_subexp):  Use filtered output, since the
2787	subroutines we call use it, otherwise the output is horribly
2788	mangled, since output of wrappable stuff comes out late.
2789
2790	* Makefile.in:  Bump VERSION to 3.98.1
2791
2792	* infrun.c (child_create_process):  Use execlp to find the
2793	shell to exec our target program.  This requires some fiddling
2794	with `environ' since there is no execlpe().
2795
2796Thu Aug  1 15:35:17 1991  Roland H. Pesch  (pesch at fowanton.cygnus.com)
2797
2798	* Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2799	Minor rearrangement of refcard permits two new make targets--
2800	gdbrc.dvi	    DVI output for refcard, using CM fonts
2801	gdbrc.ps	    PostScript refcard, using PS fonts
2802
2803Wed Jul 31 16:46:21 1991  John Gilmore  (gnu at cygint.cygnus.com)
2804
2805	* GDB-3.98 release.
2806
2807	* TODO, Projects, WHATS.NEW, README:  Update for gdb-3.98.
2808	* Makefile.in (gdb-all.texinfo):  Avoid touching file if M4 dies.
2809
2810Wed Jul 31 16:35:58 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
2811
2812	* doc/gdb.texinfo: last changes for release.
2813	Minor typo and formatting fixes; incorporated most fixes remaining from
2814	filed mail commenting on earlier drafts.
2815
2816	Added warnings: pipes don't work in run command;
2817	        conditions are converse of assertions;
2818	      	step over fn without debug info goes to next fn;
2819		vars may have "wrong" values near fn entrance, exit
2820
2821	Added example from Kingston on printing repeated nonadjacent values
2822
2823	Added explicit mention that in Emacs gdb mode C-c and C-z are like
2824	shell mode for signals
2825
2826	Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2827	doesn't sound so much like its parent "Stopping and Continuing"; also
2828	moved entries on continue to top of section, so they don't get lost.
2829
2830	Improved installation directions in appendix, added manual formatting
2831	instructions
2832
2833Tue Jul 30 17:26:39 1991  John Gilmore  (gnu at cygint.cygnus.com)
2834
2835	* configure.in:  Remove xm.h and tm.h even if we aren't linking
2836	new ones, so "./configure sun4; ./configure none" does the right
2837	thing.  Assume that alldeps.mak and depend are already built in
2838	srcdir, and avoid running "make" (particularly "make depend",
2839	which involves "gcc") from inside configure.  Build Makefile
2840	directly rather than building Makefile.conf first.
2841	* configure:  Regenerate with above changes.
2842	* Makefile.in:  Use $(BISON) to find bison.  Roll VERSION
2843	to 3.98.  Revise gdb.tar.Z procedure to produce a file
2844	called gdb-$(VERSION).tar.Z but which unpacks into a
2845	directory called "gdb".  Move non-source files out of
2846	$(SFILES_SUBDIR).  Pretty up alldeps.mak with comments.
2847	(depend):  Don't try to do "gcc expread.y".
2848	(expread.o):  Update dependencies by hand.
2849
2850Mon Jul 29 15:21:09 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
2851
2852	* doc/gdb.texinfo:
2853	Fixed a variety of small typos that prevented info from formatting
2854	cleanly; altered too-long heading for GPL Appendix, as discussed
2855	w/RMS; Changed date on cover to July 91.
2856
2857Fri Jul 26 13:20:02 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
2858
2859	* doc/gdb.texinfo:
2860	(1) Applied some fixes due to comments from Larry Breed (easier ones
2861	through chapsec 5.2)
2862	(2) Eliminated use of @footnote---had my doubts about it anyways, and
2863	it's broken in latest texinfo
2864	(3) Introduced *some* use of [] for optional arguments, where
2865	explanation is not simpler by listing cmd w arg and cmd w/out arg
2866	separately.  Still not using @deffn.
2867	(4) Dropped in GPL-2.  NOTE: one of GPL-2 or texinfo is broken; a
2868	couple of headings are too long.  Need patches to texinfo or revision
2869	to GPL-2.
2870
2871	* Partial update to README (which still needs work for this
2872	release!): (1) use of configure corrected for new script,
2873                   (2) "make gdb.dvi" and "make gdb.info" mentioned.
2874
2875Wed Jul 24 06:44:02 1991  John Gilmore  (gnu at cygint.cygnus.com)
2876
2877	* symtab.c (lookup_symbol):  Don't complain right off about
2878	no debug symbols; use the misc function vector first.
2879	(list_symbols):  Use misc function vector to find symbols
2880	that don't have debug info, and print them.
2881	(find_pc_symtab):  Temporarily avoid fatal() when psymtab
2882	PC range doesn't match symtab PC range, as it does on the
2883	MIPS because our symtab reading isn't perfect.
2884
2885	* dbxread.c (dbx_symfile_read):  Make warning about
2886	"no debug symbols" slightly nicer.
2887
2888	* source.c (select_source_symtab):  If "main" symbol exists,
2889	but decode_line_spec can't find line info, don't just return
2890	a zero; try other source symtabs or give an error.
2891
2892	* mipsread.c (parse_partial_symbols):  Sort the psymtabs by
2893	their low addresses first, then rip through fixing high addrs.
2894
2895	* ns32k-opcode.h (sfsr):  Bugfix from Rune Nerg}rd,
2896	<runene@ifi.uio.no>.
2897	(NS32K_SVC_IMMED_OPERANDS):  Reverse the #ifndef.
2898
2899Tue Jul 23 18:52:43 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)
2900
2901	* Minor, mostly mechanical, cleanup of doc subdir for clean
2902	makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2903	and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2904
2905Sun Jul 21 03:54:52 1991  John Gilmore  (gnu at cygint.cygnus.com)
2906
2907	Mostly MIPS and general symbol-reading fixups.
2908
2909	* doc/gdbint.texinfo:  Add documentation on symbol-reading
2910	interface.
2911
2912	* mipsread.c:  Remove kludges around #include "ecoff.h".
2913	Remove redefinitions of a_magic, etc, no longer used.
2914	(parse_symbol, ):  Convert "Internal:" printfs to complain()ts.
2915	Fix global overview comments to match symfile.c protocol.
2916	(mipscoff_new_init):  Eliminate cur_hdr if we have one.
2917	(mipscoff_symfile_read):  Eliminate unused code.  Avoid
2918	sorting all the symtabs, when all we have read here is psymtabs.
2919	The symtabs are sorted as they are created anyway.  Tell
2920	condense_misc_bunches whether we're mainline.
2921	(psymtab_to_symtab_1):  Pass filename when recursing, to make
2922	stack trace more informative.
2923	(parse_partial_symbols):  Assume cur_hdr as argument.
2924	(read_mips_symtab):  Don't clobber cur_hdr, so it can be freed.
2925	Pass cur_hdr implicitly to parse_partial_symbols.  Avoid checking
2926	the TYPE_NAME of char *, since that's done in symfile.c.
2927	(free_numargs, parse_symbol, add_symbol, add_block,
2928	shrink_linetable):  Declare these fns void.
2929	(upgrade_type):  Convert tree of if's to switch.  Clean up
2930	bogus "off == 0" handling with a complaint.  Avoid setting
2931	field bitpos and bitsize of array with lower and upper bounds.
2932	Check specified bitsize of elements against their actual type's
2933	bitsize, and complain if different.  Complain about unknown
2934	type qualifiers.
2935	(parse_fdr):  Don't assume sizeof(char *) == sizeof (struct *).
2936	(psymtab_to_symtab_1):  Print names of subsidiary files that
2937	are being read in.  FIXME, we read far too many files.  This code
2938	is not the problem, the problem is in parse_fdr where the psymtabs
2939	are set up.
2940	(cross_ref):  Result should indicate that we used one aux entry
2941	normally, or two if we encountered a "next" entry.  This used
2942	to leave the caller pointing at the wrong aux entry.
2943	(add_symbol):  If overflowed cur_block, reallocate it larger,
2944	chase all pointers to it, and complain(), rather than clobber memory.
2945	(shrink_block):  Use xrealloc rather than xmalloc-and-copy.
2946	(new_field):  Only allocate one field initially, not two.
2947	Pull ++ out of macro argument.  Simplify.
2948	(_initialize_mipsread):  Avoid initialization of importd
2949	global_psymbols and static_psymbols.
2950
2951	* symfile.c (psymtab_to_symtab):  Depend on XXX_psymtab_to_symtab
2952	to properly set pst->symtab; avoid searching for it.
2953	(symfile_fns):  Improve comments, add a FIXME.
2954	* dbxread.c:  Update comments to reflect symfile protocol.
2955	(read_ofile_symtab, end_symtab):  Return the symtab.
2956	(psymtab_to_symtab_1):  Set pst->symtab.
2957
2958	* coffread.c (coff_symfile_read):  tell condense_misc_bunches
2959	whether we're mainline.
2960
2961	* symfile.h (sym_fns):  Remove unused sym_discard member.
2962	* coffread.c, mipsread.c, dbxread.c:  Remove XXX_symfile_discard.
2963
2964	* mtrace.c (mtrace):  Take effect if mallwatch is set, even if
2965	the environment variable is not.
2966	* infcmd.c (finish_command):  Use filtered printfs.
2967	* cplus-dem.c:  Add struct tags to a few unnamed structs.
2968	* valops.c (value_coerce_array):  Improve comments.
2969	* valprint.c (type_print_varspec_suffix):  Print array size only
2970	if greater than zero.
2971	* m88k-tdep.c:  Shift some lines left by one space, that had
2972	apparently been trashed at some point.
2973	* TODO:  More things to do, a few got done.
2974
2975Thu Jul 18 22:46:05 1991  John Gilmore  (gnu at cygint.cygnus.com)
2976
2977	* symtab.h (LOC_EXTERNAL):  Eliminate in favor of LOC_STATIC.
2978	(ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2979	comments.
2980	* dbxread.c (read_dbx_symtab):  LOC_EXTERNAL -> LOC_STATIC.
2981	* expread.y, findvar.c, symmisc.c:  Ditto.
2982	* printcmd.c (address_info):  Update printed forms of LOC_
2983	symbols.  Elim LOC_EXTERNAL.
2984	(print_frame_args):  Keep track of param stack offsets before
2985	re-looking up to find the local register param is kept in.
2986
2987	* mipsread.c:  Use <symconst.h> and <sym.h> rather than <syms.h>.
2988	Further integration of mipsread into gdb.  Eliminate unused
2989	routines, duplicate declarations.  Handle static symbols in
2990	psymtabs as well as external symbols.  When reading symtabs,
2991	insert symbols into the correct block (global, static, or a local
2992	block).
2993	(read_mips_symtab, parse_partial_symbols):  Don't pass useless
2994	"incremental" arg.
2995	(mipscoff_symfile_read):  Don't call select_source_symtab.
2996	(parse_symbol):  Use SYMBOL_VALUE_ADDRESS where appropriate,
2997	rather than SYMBOL_VALUE.
2998	(parse_external):  Comment clobbering of top_stack.
2999	(parse_partial_symbols):  Update comments.  Allocate and parse
3000	static symbols as well as external symbols.  FIXME, enum values
3001	are not handled in this pass, but should be.  Inline new_psymbol.
3002	Use SYMBOL_VALUE_ADDRESS.
3003	(psymtab_to_symtab_1):  Read symbols into global static block
3004	by default (until enter some function's local block context).
3005	(sort_blocks):  Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
3006	(destroy_all_symtabs, new_psymbol):  Eliminate, unused.
3007
3008	* source.c (select_source_symtab):  Select a source symtab
3009	from either the symtabs or, failing that, the psymtabs.
3010	(list_command):  Update error message.
3011	(forward_search_command, reverse_search_command):  Use getc, not
3012	fgetc, for speed.  FIXME, add comment about buffers that die if
3013	overrun by long line.
3014
3015	* values.c (unpack_field_as_long, modify_field):  Avoid shifting
3016	by an entire word, which is not portable, if we have a 32-bit
3017	field.  (Code in dbxread.c already turns such bitfields, if
3018	aligned, into ordinary ints, but fixing this will help for other
3019	symbol formats and for future changes.)
3020	* core.c (core_open):  Handle ANSI const brain death.
3021	* utils.c (vprintf):  Fix varargs typo.
3022
3023Sun Jul 14 00:42:53 1991  John Gilmore  (gnu at cygint.cygnus.com)
3024
3025	* findvar.c (find_var_value):  Handle &function better.
3026	* TODO:  Document work needed on &fn and &array.
3027	* printcmd.c (print_address_symbolic):  New arg is the prefix
3028	to print if a name is printed.
3029	(print_address_demangle):  Honor "set print address" now.
3030	Use new arg above to improve spacing of output.
3031	* valprint.c (val_print):  When printing function pointers,
3032	print symbolic form too.
3033	* breakpoint.c (breakpoint_1):  Use new print_address_symbolic.
3034
3035Mon Jul  8 19:02:46 1991  John Gilmore  (gnu at cygint.cygnus.com)
3036
3037	* core.c (memory_error):  Reword error msg to mislead less.
3038
3039	* mips-pinsn.c (print_insn_arg 'd'):  Print $ with reg name.
3040
3041	* mipsread.c (read_mips_symtab, read_the_mips_symtab,
3042	parse_partial_symbols): Use newer BFD internals (external_filehdr
3043	and external_aouthdr), byte-swap the fields that we care about
3044	before using them, and make the file header data local to
3045	read_the_mips_symtab rather than global.
3046
3047Sat Jul  6 01:34:15 1991  John Gilmore  (gnu at cygint.cygnus.com)
3048
3049	* ns32k-opcode.h (movmw, movmd):  Fix opcodes.  Bug fix
3050	from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
3051
3052	* main.c (command_line_input):  Flush stdout and stderr
3053	before every call to readline.  This reportedly fixes a bug
3054	that comes up in Sys V running emacs-gdb and/or xxgdb,
3055	when stdin/out are pipes or sockets.
3056
3057Thu Jul  4 14:47:06 1991  John Gilmore  (gnu at cygint.cygnus.com)
3058
3059	* configure.in, Makefile.in:  Avoid rebuilding "depend" as much.
3060	Avoid declaring Makefile dependencies, because GNU Make stupidly
3061	tries to update it if we do.
3062
3063	* coffread.c:  Revise for minor changes to bfd internal coff
3064	indexes.
3065
3066	* configure:  If -template= is given a relative path, make it
3067	absolute before recurring in subdirectories.
3068
3069	* configure, configure.in, Makefile.in:  Install "configure" script
3070	as replacement for config.gdb.
3071	* config.gdb, Makefile.dist, Makefile.sdir:  Remove
3072	* README:  Update for configure, mostly.  FIXME.
3073
3074	* Add dec3100 as equivalent to littlemips.  Indicate in all host &
3075	target config files that they are for the host.  When the lines
3076	get copied into the Makefile, this makes it more obvious what's
3077	up.
3078
3079Mon Jun 24 23:49:07 1991  John Gilmore  (gnu at cygint.cygnus.com)
3080
3081	* sparc-opcode.h (trap opcodes):  Avoid leading spaces or
3082	tabs, which end up in the disassembler output inadvertently.
3083
3084Wed May 29 23:01:03 1991  John Gilmore  (gnu at cygint.cygnus.com)
3085
3086	Make it compile cleanly in an ANSI GCC2 environment.
3087
3088	* blockframe.c:  <stdio.h>
3089	* cplus-dem.c:  free takes a void *, ifdef __STDC__
3090	* dbxread.c (read_huge_number):  avoid gcc2 bug hoisting calc of
3091	LONG_MAX/radix.
3092	* defs.h (alloca):  Avoid doing anything if alloca already def'd.
3093	* stddef.h, stdlib.h:  Remove these files.
3094	* symtab.c:  Avoid declaring qsort, close.
3095	* symfile.c:  Avoid declaring close.
3096	* utils.c (vprintf):  Declare "ap" arg as proper va_alist.
3097	* sparc-tdep.c:  Avoid including lots of Sun-host-specific files.
3098
3099	Assorted other changes.
3100	* dbxread.c:  include "libaout.h", not "liba.out.h".
3101	* printcmd.c (print_frame_args):  Set recurse properly for
3102	indentation of struct and array parameters.
3103	* valops.c (value_cast):  Allow cast to void.
3104	* infrun.c (resume):  If NO_SINGLE_STEP, call machine dependent
3105	single_step() in a target-independent fashion.
3106	* sparc-tdep.c (single_step):  Don't call ptrace ourselves, just
3107	set up to be ready to continue.  This makes us target independent.
3108	* infptrace.c (child_resume):  Remove call to single_step; now
3109	can single step a SPARC target of any kind.
3110
3111Wed May 22 18:18:24 1991  Roland H. Pesch  (pesch at fowanton.cygnus.com)
3112
3113	* Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
3114	docn into separate sections---basically chapters, plus two loose
3115	pieces that can be configured to go in different places.  This
3116	allows GNU m4 to preprocess the manual without coredumping.
3117
3118	* Makefile.dist: tell TeX where to find texinfo.
3119
3120Mon May 20 12:15:04 1991  Roland H. Pesch  (pesch at fowanton.cygnus.com)
3121
3122	* Makefile.dist, doc/gdb.texinfo: respectively create, and use,
3123	the new target "rdl-apps.texinfo" which captures the Makefile
3124	variable that records where to find the Readline libraries.
3125
3126Sun May 19 05:36:59 1991  John Gilmore  (gnu at cygint.cygnus.com)
3127
3128	* tahoe-pinsn.c:  #include "tahoe-opcode.h", not "opcode.h".
3129	* tm-tahoe.h (FIX_CALL_DUMMY):  Ignore more parameters.
3130	* defs.h (const, volatile):  Only define if not already defined.
3131	* Makefile.dist (gdb.tar.Z):  Create doc subdir w/out CVS/RCS crud.
3132
3133	* README:  Update for release 3.95.
3134	* config.gdb:  Don't create readline dir in subdir builds.
3135	* main.c:  Include with "..." form for non-system include files,
3136	so "gcc -MM" for "make depend" works.
3137	Include readline files with "...h" rather than <readline/...h>.
3138	* mipsread.c:  Include "ecoff.h" rather than "intel-coff.h".
3139
3140	* coffread.c:  Undo minor damage done by Rich Pixley.  Use
3141	different internal and external representations of COFF
3142	data structures.  Use new BFD routines for swapping them in and
3143	out.
3144	* symfile.c (free_named_symtabs):  Avoid freeing file names that
3145	are null or empty.  Old i960 tools seem to produce files that
3146	claim to have empty names, causing each successive file read
3147	to blow away the previous one.
3148	* sparc-xdep.c (deferred_stores):  Repair minor damage by Rich.
3149	Move deferred_stores to top of file, but don't separate its
3150	#define's from its variable.  Add commentary.
3151	* Makefile.dist:  Fix Rich damage; undo "configure" changes in
3152	favor of keeping the (working) config.gdb.  Move readline
3153	library up a notch.
3154
3155Fri May 17 12:49:56 1991  Per Bothner  (via gnu at cygint.cygnus.com)
3156
3157	* dbxread.c (read_struct_type):  Try to handle g++ version 1 MI
3158	debug info.
3159	* infptrace.c (fetch_registers):  no result, since now void.
3160	* tconfig/news:  target depends on m68k-tdep too.
3161
3162Fri May 17 14:40:14 1991  Roland H. Pesch  (pesch at fowanton.cygnus.com)
3163
3164	* Makefile.dist: added readline/inc-*.texinfo to dependencies for
3165	gdb.dvi target
3166
3167	* readline/inc-history.texinfo, readline/inc-readline.texinfo:
3168	applied various small fixes due to or inspired by RMS comments
3169
3170	* doc/gdb.texinfo: finished using all RMS comments, save those for
3171	appendices on readline and cmd history (which are in other source
3172	files)
3173
3174Thu May 16 18:06:05 1991  Roland H. Pesch  (pesch at fowanton.cygnus.com)
3175
3176	* doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
3177	chapter 9; (2) documented 'break' command's menu mode for
3178	overloaded names, in response to hgs problem report C++ p-31
3179
3180Wed May 15 11:02:48 1991  Roland H. Pesch  (pesch at fowanton.cygnus.com)
3181
3182	* doc/gdb.texinfo: (1) better introductory example; (2) more
3183	consistent use of @code, @samp, @file, @kbd throughout; small
3184	cleanups to first three nodes; (3) new "Contributors" node;
3185	(4) Appendix, Renamed Commands; (5) divert specialized startup
3186	instructions to "Targets" chapter for generic manuals, while
3187	leaving them up front for manuals specific to specialized
3188	environments; (6) apply fixes from RMS comments through chapter 4.
3189
3190	* pretex.m4: modify explanatory text slightly (and redefine
3191	"regexp") to keep GNU m4 from complaining.  (It still crashes
3192	later, but one step at a time...)
3193
3194Wed May 15 10:32:12 1991  John Gilmore  (gnu at cygint.cygnus.com)
3195
3196	* readline/readline.c (update_line):  Avoid dereferencing a pointer
3197	before comparing it to its bounds.  Saber caught this.
3198	(init_terminal_io):  Don't set BC from the "pc=" termcap variable,
3199	and only set PC if tgetstr returned non-null.  Saber caught this.
3200
3201Tue May 14 16:29:53 PDT 1991  Roland Pesch (pesch at cygint.cygnus.com)
3202
3203	* Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
3204	stuff for config manual) here where it counts; updated
3205	to use new subdir structure (gdb/doc/).
3206
3207	* Makefile: generated from above via
3208		    config.gdb none
3209	before checkin
3210
3211	* gdbint.texinfo: added instructions on generating gdb.info* files
3212	locally for release.  These are ordinary info
3213	files, formatted from gdb.texinfo (via gdb-all.texinfo, see
3214	Makefile)---but due to use of texinfo 2, can't count on makeinfo
3215	to generate these, so we distribute them already formatted.
3216
3217	* gdb.texinfo: included full Info node and menu crud (as generated
3218	by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
3219
3220	* Makefile: updated "gdb.dvi" target to use M4 preprocessor;
3221	put in comments-for-future gdb.info target (one day makeinfo will
3222	work again).
3223
3224Tue May 14 13:51:36 PDT 1991  Roland Pesch (pesch at cygint.cygnus.com)
3225
3226	* gdb.texinfo: Updated to include new or old undocumented
3227	commands, at least the following (perhaps some others I forgot to
3228	record): info f, info float, info path, info program, info s, info
3229	set, info source, info terminal, info types, info user, set/show
3230	print object.
3231	Also covered all recent GDB command renames for v4.
3232
3233Mon May 13 14:57:46 1991  John Gilmore  (gnu at cygint.cygnus.com)
3234
3235	* mipsread.c:  Rather than keeping count of how many symtabs
3236	and psymtabs we have, for sorting purposes, count them when
3237	we need to sort.  This fixes bug in rereading of symbol tables.
3238
3239Fri May 10 15:43:33 PDT 1991  Roland Pesch (pesch at cygint.cygnus.com)
3240
3241	* infcmd.c: renamed "info path" to "show paths"
3242        * gdbrc.tex: documented above.
3243
3244Wed May  8 04:51:11 1991  John Gilmore  (gnu at cygint.cygnus.com)
3245
3246	* remote.c:  Fix comments.
3247	* utils.c (error):  Force out any pending wrap output.
3248
3249Sat May  4 11:11:07 1991  John Gilmore  (gnu at cygint.cygnus.com)
3250
3251	* Makefile.dist:  Roll VERSION to 3.95.
3252	Fix up "saber_gdb" to work again.
3253	* saber.suppress:  Update.
3254
3255	* coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
3256	symtab.h, target.c, target.h:  Lint.
3257	* core.c:  setup and select frame after reading shared libs,
3258	else reading shared libs will clobber them.  Lint.
3259	* utils.c (error):  Force out any buffered wrap text.
3260
3261Fri May  3 22:01:56 1991  John Gilmore  (gnu at cygint.cygnus.com)
3262
3263	* remote.c:  Remove decls of memory_insert_breakpoint
3264	and memory_remove_breakpoint, no longer used.  (Suggestion of
3265	Jan Norden).
3266
3267	* Makefile.dist:  use ${subdir} in paths of BFD and LIBIBERTY,
3268	to make it easier to interface to "configure"'d libraries.
3269
3270Fri May  3 13:10:01 PDT 1991  Roland Pesch (pesch at fowanton.cygnus.com)
3271
3272        * valprint.c:  introduce "set p", "set pr", "show p" and "show pr" as
3273	aliases for set/show print.

3309
3310	* gdbcore.h (write_memory): Don't prototype it.
3311
3312	* tm-88k.h, m88k-tdep.c: Make stack_error, stack_jmp global.
3313	m88k-xdep.c: Don't mention stack_error.
3314
3315	* {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
3316

3325	dc_dcontext_t not int.
3326
3327	* coffread.c [TDESC]: Use system include files not <intel-coff.h>.
3328

3331
3332	* cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
3333
3334	* signame.c: Cast const char* to char* when assigning to sys_siglist.
3335
3336	* utils.c (strsave): Make arg const char* not char*.
3337
3338	* infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
3339	bpstat_explains_signal (stop_bpstat) not stop_breakpoint.
3340
3341	* tm-88k.h (START_INFERIOR_HOOK): Make tdesc_handle a dc_handle_t.

3356
3357Thu May  2 17:53:56 1991  John Gilmore  (gnu at cygint.cygnus.com)
3358
3359	Mips bringup and general cleanup
3360
3361	* cplus-dem.c:  Move CPLUS_MARKER define to after defs.h.
3362	* infptrace.c (PT_WRITE_D, PT_READ_D):  Use correct values.
3363	(This still doesn't seem to make MIPS bkpts work.)
3364	* mipsread.c:  Remove dup "Reading symbol data..." msg.
3365	(symbol_file_command, add_file_command):  Remove, obsol.
3366	* printcmd.c (ptype_command):  Say "an enum" rather than "a enum".
3367	Wrap output appropriately.

3773
3774Sun Apr 14 23:08:34 1991  Jim Kingdon  (kingdon at cygint.cygnus.com)
3775
3776	* inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
3777	New function to give correct error message.
3778
3779Thu Apr 11 17:19:41 1991  Jim Kingdon  (kingdon at cygint.cygnus.com)
3780
3781	* target.h: Add to_doc and target_preopen.
3782	target.c: Add target_preopen and target_command.
3783	Remove target_info.
3784	(add_target): Call add_cmd and mess with targetlist->doc.
3785	core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
3786	remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
3787	Call target_preopen from open routine.
3788
3789	* main.c: Rename editing_info to show_commands.
3790	(_initialize_main): Rename "info editing" to "show commands".
3791
3792	* source.c: Rename directories_info to show_directories.
3793	(_initialize_values): Rename "info directories" to "show directories".
3794
3795	* values.c: Rename convenience_info to show_convenience.
3796	(_initialize_values): Rename "info convenience" to "show convenience".
3797
3798	* copying.awk (_initialize_copying): Rename "info copying" to
3799	"show copying" and "info warranty" to "show warranty".
3800	Rename {copying,warranty}_info to show_{copying,warranty}.
3801
3802	* symfile.c: Rename add_syms_command to add_symbol_file_command.
3803	(_initialize_symfile, add_syms_addr_command):
3804	Rename add-syms to add-symbol-file.
3805
3806Thu Apr 18 18:08:30 1991  John Gilmore  (gnu at cygint.cygnus.com)
3807
3808	* symfile.h (free_named_symtabs):  Rename from free_named_symtab.
3809	* symfile.c (clear_symtab_users_once, cashier_psymtab,
3810	free_named_symtabs):  Move these routines from symmisc.c.
3811	* symmisc.c (same):  same.
3812	(free_symtab):  Make non-static.
3813	* symtab.h (free_symtab):  Declare as exported void fn now.
3814	* dbxread.c (end_symtab, end_psymtab):  Change comments.
3815	(initialize_dbxread):  Call dbx_new_init() in case the first
3816	command is add-symbols.
3817	* target.c (dummy_target):  Permit add_syms_addr_command.
3818
3819Sat Apr 13 14:46:07 1991  John Gilmore  (gnu at cygint.cygnus.com)
3820
3821	Permit symbols to be superseded when new symbol files have
3822	been read in, particularly for VxWorks.
3823
3824	* dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3825	to the main file, as well as to include files.  Also, put global
3826	functions into the global psymtab, to make "i fun" work.
3827	(end_psymtab):  Free named symtabs and psymtabs for a file, once a
3828	new psymtab for it has been read.
3829	* coffread.c (end_psymtab):  Free named symtabs and psymtabs for
3830	a file, once a new symtab has been read for it.
3831	* mipsread.c:  FIXME.  We need to do the same for MIPS, but it
3832	looks harder to determine the top-level block before it's been
3833	queued to the psymtab list.
3834
3835	* symfile.c (symbol_file_add):  Use filtered printing and wrap it.
3836	If we have wiped out any old symbol tables, clean up at end of
3837	symbol reading.
3838	(symbol_file_command):  Don't reference symfile_fns if it's zero.
3839
3840	* symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK):  New
3841	defines for the blocks of a blockvector that contain global and
3842	file-static symbols and the first of the smaller scope contours.
3843	* symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3844	decode_line_1, make_symbol_completion_list):  Use the above.
3845	* coffread.c (end_symtab, patch_opaque_types):  Ditto.
3846	* dbxread.c (end_symtab):  Ditto.
3847	* expread.y (block):  Ditto.
3848	* mipsread.c (throughout):  Ditto.
3849	* symmisc.c (free_named_symtabs):  Ditto.
3850
3851	* symtab.c (list_symbols):  Process the first symbol of the
3852	static psymbols list.
3853	(types_info):  Restore this function from its untimely #if 0.
3854	It's not perfect, but it is better than nothing.
3855	(_initialize_symtab):  Restore "info types".
3856
3857Thu Apr 11 05:23:19 1991  John Gilmore  (gnu at cygint.cygnus.com)
3858
3859	* m68k-stub.c:  Remote stub for 680x0's, created from
3860	rem-m68k.shar (which is removed).
3861	* nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3862	Remove RCS log stuff now that we use CVS and it blows our diffs.
3863
3864Wed Apr 10 14:18:06 1991  John Gilmore  (gnu at cygint.cygnus.com)
3865
3866	* symmisc.c (free_named_symtab):  Make it work, in its current
3867	kludgy fashion.  Change result to indicate if we blew away bkpts.
3868	* dbxread.c (end_symtab):  Accumulate result from
3869	free_named_symtab and print warning if we blew user's state.
3870	* symfile.h:  free_named_symtab now returns an int.
3871
3872Mon Apr  8 23:57:43 1991  John Gilmore  (gnu at cygint.cygnus.com)
3873
3874	* dbxread.c (dbx_symfile_read):  Initialize psymbol list if this
3875	is the first symbol read, even if not mainline.
3876	(dbx_psymtab_to_symtab):  symfile might be zero, cope.
3877	* exec.c (exec_ops):  Add_syms_addr is valid in our tvec.
3878	(set_section_command):  New command ("section xxx yyy" -- should
3879	be renamed to "set section xxx yyy" FIXME) which sets the
3880	base address of a section of the exec file, overriding the
3881	virtual address that BFD reports.
3882
3883Fri Apr  5 17:14:39 1991  John Gilmore  (gnu at cygint.cygnus.com)
3884
3885	* exec.c:  Add add_syms_addr_command to exec_ops, so you can
3886	load symbols at any address while examining an exec file.
3887
3888Thu Apr  4 10:09:35 1991  John Gilmore  (gnu at cygint.cygnus.com)
3889
3890	* tm-i386v.h (FLOAT_INFO):  Don't define it, since the code
3891	for printing the float info is host-dependent, not
3892	target-dependent.  FIXME.
3893	* i386-pinsn.c:  Move #includes to top, remove useless ones.
3894	* i386-tdep.c:  Don't bother including <.../reg.h> since we
3895	don't use it (and it doesn't exist on host systems).
3896
3897	* ieee-float.c (ieee_extended_to_double):  Convert NaN to Inf.
3898	Convert negative numbers properly.
3899	(ieee_test):  Make numbers really random; fix format arg.
3900
3901	* infcmd.c (attach_command, detach_command):  Don't repeat on CR.
3902	* core.c (core_detach):  Unpush core_ops, which might not be on
3903	top.  We used to just pop the top, which broke things.  Don't
3904	need dont_repeat() any more.
3905	(core_file_command):  Psst!  Don't repeat it.
3906	* remote-nindy.c (nindy_detach):  Don't need dont_repeat() now.
3907	* expprint.c (print_subexp):  Avoid switch fallthru on
3908	BINOP_ASSIGN_MODIFY, so we can print += and such.
3909	* frame.h:  Fix typo.
3910	* inflow.c (kill_command):  After killing inferior, print our
3911	current frame in the core file, if we have one.
3912	(generic_mourn_inferior):  When inferior dies, either select
3913	the current frame (in the new target, e.g. core file), or
3914	set both the current and selected frames to NULL.
3915
3916	Changes from Peter Schauer.
3917
3918	* infptrace.c:  Avoid <sys/ptrace.h> on USG.
3919
3920	* Make all file names fit in 14 characters (sigh and damn!):
3921	mv hp300hpux-xdep.c hp300ux-xdep.c
3922	mv symmetry-xdep.c symm-xdep.c
3923	mv symmetry-tdep.c symm-tdep.c
3924	mv convex-opcode.h convx-opcode.h
3925	mv tm-vxworks960.h tm-vx960.h
3926	mv tm-vxworks68.h tm-vx68.h
3927	mv Makefile.srcdir Makefile.sdir
3928	mv gdb-int.texinfo gdbint.texinfo
3929	mv remote-sa.m68k.shar rem-m68k.shar
3930	mv remote-multi.shar rem-multi.shar
3931	* Makefile.dist, README, config.gdb, convex-pinsn.c,
3932	tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3933	xconfig/hp300hpux, xconfig/symmetry:  Change names to shorter
3934	names.
3935
3936	* command.c (user_info_1, user_info):  New command for listing
3937	the user-defined commands.
3938
3939Wed Apr  3 15:00:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
3940
3941	* dbxread.c (really_free_pendings):  Clear file_symbols
3942	and global_symbols after freeing them; otherwise, running
3943	this function twice (if it appears twice on the cleanup
3944	chain), we try to free things twice.
3945
3946	* dbxread.c (read_dbx_symtab):  Calculate end_of_text_addr
3947	based on text_addr (the address of text in core), not on addr (the
3948	offset between text in the .o file and in core).  This change
3949	is from Peter Schauer.
3950
3951	* main.c:  Define ALL_CLEANUPS as a cast of zero.
3952	(return_to_top_level):  Use it.
3953	(main):  Do all cleanups after each command run as part
3954	of the gdb startup sequence.  Also do all cleanups before
3955	entering the command loop, and every time we exit the command
3956	loop and reenter.  Before, the cleanups from the startup sequence
3957	were being left undone until the first error!
3958	(command_loop):  Rename do_nothing cleanup to command_loop_marker
3959	so we can see it easily when examining the cleanup chain.
3960	(init_signals):  Add another do_nothing for signal handling.
3961	(quit_command):  Only try to kill target if it has execution.
3962	Problems in the target stack got us into a state where
3963	inferior_pid was nonzero but none of the targets had execution.
3964	In this state you couldn't exit gdb.
3965
3966	* dbxread.c:  Two changes from Peter Schauer.
3967	(echo_command):  Fflush output after an echo command.
3968	(show_history):  Pass all args to cmd_show_list.
3969
3970	* utils.c (init_malloc):  Call mtrace to turn on tracing
3971	if the environment variable MALLOC_TRACE is set to a file name.
3972	* mtrace.c:  Add source file which provides a log of every malloc,
3973	free, and realloc to a trace file.
3974	* mtrace.awk:  Add source file which analyzes the trace file.
3975	* Makefile.dist (GNU_MALLOC, MALLOCSRC):  Add mtrace.{c,o,awk}.
3976	(VERSION):  Roll to 3.94.3.
3977
3978	* breakpoint.c (breakpoint_1):  Add a space to "i watch" output.
3979	(check_duplicates):  Don't bother with watchpoints.
3980	(set_raw_breakpoint):  Comment about danger of this routine.
3981	(watch_command):  Parse and eval all args before calling
3982	set_raw_breakpoint.
3983
3984	* solib.c (find_solib):  Avoid error in referencing memory to
3985	see if any more shared libraries have been added.  This is
3986	particularly useful if the target has terminated.  Bug reported
3987	by Peter Schauer.
3988
3989	Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3990	in bringing up 3.94.2 on the Sun-3.
3991
3992        * Makefile.dist:  Include CFLAGS in rule for cplus-dem.o.
3993        * breakpoint.c (enable_breakpoint):  Check for valid watchpoint
3994        expression (in scope) before reenabling watchpoint.
3995	* signame.c (init_sigs):  Add missing declaration of i, fix
3996	sys_siglist declaration.
3997	* source.c (list_command):  Fixed range computation to use
3998	lines_to_list ().
3999	* stack.c (backtrace_command):  Do not allow command if target has
4000	no stack, print informative error message.
4001	* target.c (target_command):  Do not write into command line
4002	because this fails if the target command is used in a user defined
4003	command.  [This change was enhanced by gnu to support any-
4004	unique-prefix matching on target names.]
4005	* valops.c (value_struct_elt):  Avoid infinite loop on an
4006	erroneous attempt to print the member of function (try p main.p).
4007
4008Mon Apr  1 17:05:45 1991  John Gilmore  (gnu at cygint.cygnus.com)
4009
4010	* expread.y (name_no_typename):  Avoid reduce/reduce errors
4011	caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
4012	Since the GDB parser really doesn't use name_no_typename in a
4013	name-only context, the parser can't tell the diff between
4014	names and numbers here.  Avoid allowing a name_no_typename
4015	to be a NAME_OR_*INT to resolve the conflict.
4016
4017Sun Mar 31 20:12:07 1991  John Gilmore  (gnu at cygint.cygnus.com)
4018
4019	Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
4020
4021	* valprint.c (val_print_fields):  bitfield printing didn't handle
4022	byte order.  Indirect through a few more fns to cope.
4023
4024	* values.c (modify_field):  also cope with byte order.
4025
4026Sat Mar 23 10:02:21 1991  John Gilmore  (gnu at cygint.cygnus.com)
4027
4028	Cleanup for release 3.94.2:
4029
4030	* Makefile.dist: Pull REMOTE_OBS.  Fix saber includes for BFD
4031	include files.  Roll version to 3.94.2.
4032
4033	* coffread.c (init_stringtab):  Read length into unsigned char
4034	array before swapping; don't assume 32-bit longs.
4035
4036	* target.c (target_info): Don't bother with get_sym_file, just use
4037	the symfile global variable.
4038	* symtab.h, symfile.c (get_sym_file):  Delete it.
4039
4040	* dbxread.c (dbx_symfile_init):  Don't depend on long == 4 bytes.
4041	(define_symbol):  Set symbol line number to 0 if not gcc-compiled.
4042	(read_type):  Replace one more error() with complain().
4043
4044	* mipsread.c (parse_partial_symbols):  Replace printf with complain.
4045
4046	* i960-tdep.c:  Fix copyright attribution.
4047
4048	* config.gdb:  Quote all backquotes in doublequotes.  You can
4049	quote me on that.  BSD 4.4 shell found this one.
4050
4051	* infptrace.c (throughout):  The third argument to ptrace is an
4052	int *, not an int.
4053
4054	* infrun.c (wait_for_inferior):  When program has terminated, we
4055	have to call target_terminal_ours before we pop that target off
4056	the stack (e.g. before a call to target_kill or
4057	target_mourn_inferior).  This fixes problem where a program
4058	terminates, then GDB stops for (tty output) and you have to type
4059	"fg" to the shell to resume it.  FIXME:  This code for what to
4060	do after termination really should be in normal_stop instead.
4061
4062	* gdbcore.h (read_memory_check):  Change declaration; it changed
4063	names months ago.
4064
4065	* terminal.h:  Include <sgtty.h> before <sys/ioctl.h>, since in BSD
4066	4.4 prereleases, this avoids a bug in their sgtty compatability
4067	support.
4068	* remote.c:  Use terminal.h rather than hand-rolling the same.
4069
4070	* signame.c, signame.h (psignal):  Arg is unsigned, not int.
4071	* utils.c (strsave, strstr):  Fix arg types.
4072	* valprint.c (val_print):  lint
4073
4074	MIPS symbol table support from Per Bothner:
4075
4076	* symfile.c (symtab_fns):  Remove initializer table that needs to
4077	be hacked for each new symbol file format supported.
4078	(add_symtab_fns):  New function, chains symbol table
4079	handlers into the global list.
4080	(symfile_init):  Search this list.
4081	* symfile.h:  Add next pointer, declare add_symtab_fns.
4082	* coffread.c (_initialize_coffread): Call add_symtab_fns.
4083	* dbxread.c (_initialize_dbxread):  Call add_symtab_fns.
4084
4085	* mipsread.c (psymtab_to_symtab_1): return void instead of (struct
4086	symbol *).  Thus, we no longer need the hack to trash
4087	pst->filename.  Good, since that hack confused code in symfile.c!
4088
4089	(reorder_symtabs, destroy_all_symtabs):  Removed static
4090	all_symtabs, which was used to qsort symtabs in reorder_symtabs.
4091	Instead, the latter now uses a temporary array (stack-allocated
4092	from an obstack, and then freed).
4093
4094	(parse_symbol):  Added a hack to fix up BLOCK_{START,END} if they
4095	haven't been set in the outermost stBlock of a procedure. This was
4096	a problem with f77 binaries on Ultrix 4.?.
4097
4098	(new_symtab, new_symbol, new_type):  Continue changing code to use
4099	obstacks more and otherwise conform to dbxread internal style.
4100	Made the free_code of symtabs be free_linetable (as in dbxread)
4101	instead of free_contents.  This implies memory leaks when reading
4102	a new symbol table, until the conversion is finished. Did change
4103	(struct symbol) and (struct type) to be allocated on the
4104	symbol_obstack.  Blocks and blockvectors are among the things
4105	still "leaking."
4106
4107	* mipsread.c (parse_partial_symbols, parse_fdr):  It hasn't been
4108	tested much, but it solved one problem (reported by Meissner), and
4109	cleans up some other things.  The problem happened when an
4110	included file contains actual code (functions) and not just
4111	definitions. The mips coff is a little inconvenient there, since
4112	it may cause a procedure to be mapped to the wrong psymtab.
4113
4114	* mips-tdep.c (heuristic_proc_desc):  Minor cleanup.
4115	* mips-xdep.c (fetch_core_registers):  Minor cleanup.  FIXME,
4116	this will need work for the new core paradigm.
4117
4118	Opcode patches from the net:
4119
4120	* mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
4121	ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
4122	missing altogether - they are added here.  From Bruce Bauman.
4123	* mips-opcode.h:  The low mask for C0 instructions was too small.
4124	From Garrett Lau.  I modified the fix to check the entire 32-bit
4125	opcode.
4126
4127	* ns32k-opcode.h:  Fix opcodes for deiw and deid.  From Bruce
4128	Bauman.
4129
4130Thu Mar 21 12:56:46 1991  John Gilmore  (gnu at cygint.cygnus.com)
4131
4132	Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
4133
4134	* dbxread.c (read_type): Pointer subtraction (value_sub in
4135	valarith.c) sometimes failed because the types of the
4136	 pointers being subtracted were not identical.
4137	These differed because dbxread.c was allocating pointer types
4138	using dbx_alloc_type+smash_to_pointer_type instead of
4139	lookup_pointer_type. I failed to find a justification for the
4140	former, so I changed it to use the latter. Similarly, I
4141	replaced smash_to_function_type by lookup_function_type,
4142	and smash_to_reference_type by lookup_reference_type.
4143
4144	* mipsread.c (parse_symbol, upgrade_type, parse_procedure,
4145	_initialize_mipsread):  corresponding changes.
4146
4147	* symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
4148
4149	* source.c (mod_path): Do tilde_expand on each component of the path,
4150	rather than on the (list of) paths as a whole.
4151	(print_source_lines):  Set first_line_listed in addition to
4152	current_source_symtab and current_source_line.  If the source was
4153	not findable, after a "dir" command to fix the problem,
4154	a "list" would get the wrong lines.
4155
4156	While I was there... (gnu):
4157
4158	* dbxread.c (read_type):  Change error to complaint.
4159
4160Thu Mar 21 12:56:46 1991  John Gilmore  (gnu at cygint.cygnus.com)
4161
4162	First attempt at detailed understanding of symbol table memory alloc.
4163
4164	* dbxread.c (dbx_symfile_read):  Free our string table if we
4165	aren't the mainline.  Free the "info" struct since we're done with
4166	it.
4167	(init_psymbol_list):  Free any previously allocated psymbol lists.
4168	(): FIXME: Should realloc-down the psymbol lists when done reading

4172
4173	* xm-hp300hpux.h (USG):  #undef then #define so Makefile can -D.
4174	(REGISTER_ADDR):  Make result type unsigned int.
4175
4176	* xconfig/{i386*,hp300hpux,altosgas,altos}:  All config files that

4294	examination anyway.
4295	* core.c (core_ops):  Use child_attach and child_create_inferior
4296	rather than default attach and create_inferior functions.

4298	Handle floating point registers in core files.
4299
4300	* sparc-xdep.c (fetch_core_registers):  Rewrite for float support.

4302	This version untested since BFD doesn't yet support sun3 core
4303	files.
4304	* hp300hpux-xdep.c:  Rewrite fetch_core_registers to new calling
4305	conventions.  Fix comments and style.  This version has not
4306	been compiled yet, since we have no HP inhouse.
4307	* core.c (get_core_registers):  Look for two sections, ".reg"
4308	and ".reg2", and pass both to fetch_core_registers sequentially.
4309

4311
4312	* source.c (forget_cached_source_info):  Not static any more.

4314	(dir_command):  Handle variable arguments ($cdir, $cwd).
4315	(source_info):  Print "Compilation directory" rather than
4316	"Originally compiled in" to remind people of $cdir.

4318	(open_source_file):  If compilation directory is known, replace
4319	first $cdir in path with the compilation directory.
4320	(print_source_lines):  Even if we can't print the lines, set the
4321	current symtab and line for future commands like "info source" or

4323	line number, and file access error message.
4324	(_initialize_source):  Fix help text to describe changes.
4325	* main.c (cd_command):  Forget cached source info when we chdir.

4331	Byte-swap COFF symbol tables if necessary when reading them in.
4332	Use complain() to replace error message in one spot.  Needs

4334	swapping routines non-static.
4335
4336Mon Mar  4 00:53:40 1991  John Gilmore  (gnu at cygint.cygnus.com)

4353Sat Mar  2 15:47:55 1991  John Gilmore  (gnu at cygint.cygnus.com)
4354
4355	* i960-tdep.c (examine_prologue):  Add new argument limit,
4356	which stops the scan at the end of the prologue, or at the PC.
4357	This fixes a problem where it walks down into the code for the
4358	user's statements if that code looks like function prologues.
4359	Mark Fox and I have been bouncing this code back and forth, making
4360	small changes to it.  Callers changed to match.
4361
4362Tue Feb 26 01:47:07 1991  Cygnus John Gilmore  (cygnus at yuba)
4363
4364	Cleanup for gdb-3.94 release final:

4378	* am29k-tdep.c:  Add contribution line.
4379	(examine_prologue):  Cache information about function prologues in

4383	* core.c (core_close):  New function made from cleanup_core.
4384
4385	* core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,

4389	add_file.  Break out close routine from existing code.
4390
4391	* dbxread.c (really_free_pendings):  Don't free pending_blocks;
4392	they are in an obstack.
4393	(read_dbx_symtab):  Relocate end_of_text_addr in the psymtab.
4394	Lint.
4395	(define_symbol):  Add symbol type parameter; change callers;
4396	pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
4397	it to influence the symbol class on the i960.
4398	(define_symbol):  Swap LOC_CONST's into target byte order.
4399
4400	* exec.c (exec_close):  New function.
4401	(exec_file_command):  Call it.
4402
4403	* findvar.c (read_relative_register_raw_bytes):  Doc byte order,
4404	Fix byte order of frame pointer.
4405	(read_var_value):  Result of 0 if var's value can't be found,
4406	e.g. missing FRAME_ARGS_ADDRESS.  Byte-swap LOC_CONST and
4407	LOC_LABEL values to target order.  Add LOC_LOCAL_ARG.
4408	(locate_var_value):  Use read_var_value and use its lazy address
4409	as the location of the var's value.  Lint.
4410
4411	* i960-pinsn.c (next_insn):  Add routine from vxgdb for scanning
4412	instructions.
4413
4414	* i960-tdep.c (arg_address, i960_frame_find_saved_regs):  Remove
4415	obsolete Intel versions in favor of vxgdb versions.
4416	(check_host, byteswap, byteswap_val, reorder_val):  Eliminate
4417	code dealing with byte order of values, which Intel did in host byte
4418	order rather than gdb-4's target byte order.
4419	(i960_frame_chain_valid):  Move to nindy-tdep.c.
4420	(examine_prologue, skip_prologue, frame_find_saved_regs,
4421	frame_args_address, leafproc_return, saved_pc_after_call,
4422	pop_frame):  Add vxgdb versions from Mark Fox.
4423	(examine_prologue, frame_struct_result_address):  Add code
4424	to deal with the saved value of G13 (struct return address

4426	(frame_args_address):  Modify Mark's version to prefer the
4427	saved value over the current value in the topmost frame.
4428	Cache result in the frame info to avoid performance hair in
4429	callers.
4430	(print_fault):  Add gdb960 code for printing faults.
4431	(_initialize_i960):  Actually call check_host.
4432
4433	* ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
4434	add stub routines.  FIXME, these currently just return zero!
4435
4436	* infcmd.c (program_info):  Use PRINT_RANDOM_SIGNAL.
4437	(attach_command):  Call target_attach, not target_open, now.

4440	(child_attach):  Rename from child_open.
4441	(wait_for_inferior): Use PRINT_RANDOM_SIGNAL.  If stop_pc is zero,

4445	(child_files_info):  Clean up message a bit.

4447
4448	* mem-break.c:  #ifdef out the whole file if BREAKPOINT is not
4449	set (e.g. on VxWorks or NINDY).  Move read_memory_nobpt from
4450	findvar.c to here, since it depends on the contents of the
4451	shadow_contents of breakpoints, but keep if #if 0 since it is
4452	never called.
4453
4454	* nindy-tdep.c:  New file, contains nindy_frame_chain_valid, moved
4455	from i960-tdep.c.

4459	have_core_file_p in favor of target_has_stack or
4460	target_has_execution.
4461	(print_frame_args):  Handle LOC_LOCAL_ARG.  Eliminate duplicate
4462	code for actually finding the values of arguments, though we still
4463	keep track of the maximum stack offset for use in printing unnamed

4465
4466	* remote-nindy.c (i960_print_fault):  Move to i960-tdep.c.
4467	(struct nindy_regs):  Define registers passed to/from nindy.
4468	(nindy_fetch_registers, nindy_store-registers):  Translate between
4469	nindy and GDB formats for the registers.
4470	(dcache_init):  Statically allocate the cache, since it was being
4471	allocated by a malloc that was never freed anyway.
4472	(nindy_create_inferior):  Error, not core dump, if no exec file.
4473	(nindy_before_main_loop):  Use target_load, not target_add_file.

4481	(vx_read_register, vx_write_register):  Cleanup status checking.
4482	#ifdef the code based on which CPU we are using (960 or 68k),
4483	FIXME, this should be completely general but it isn't yet.
4484	(vx_xfer_memory, vx_resume):  Cleanup status checking.
4485	(vx_run_files_info):  Improve message.
4486	(vx_load_command):  Renamed from vx_add_file_command.  Allow load
4487	to be interrupted.
4488	(net_ptrace):  Remove unused routine.
4489	(vx_wait):  Adopt code from vxgdb960 to cope with broken
4490	connections to target machine and prompt to disconnect.  Remove
4491	debug printouts.  Map some EVENT_'s to SIGnals.
4492	(add_symbol_stub, vx_open):  Print names of object files we found,
4493	and "ok" if we read their symbols OK.  Clarify output in general.
4494	(vx_attach, vx_detach, vx_kill):  Add these commands.
4495	(vx_convert_from_virtual, vx_convert_to_virtual):  Simplify.
4496	(vx_run_ops):  Turn off all_mem, to avoid spurious msg in the
4497	"info files" output, and create_inferior, since we already have
4498	an inferior.
4499
4500	* stack.c (frame_info):  Replace Frame_unknown with 0.
4501	(print_frame_arg_vars):  Handle LOC_LOCAL_ARG.
4502	(return_command):  Pop until the PC matches as well as the FP,
4503	so it works even if the FP is shared with another function,
4504	as in "frameless" or "leaf" procedures.
4505
4506	* symfile.c (load_command):  renamed from add_file_target_command.
4507	(add_syms_addr_command):  renamed from add_file_addr_command.
4508	(add_syms_command):  Stub to call target_add_syms.
4509	(_initialize_symfile):  Change command names and descriptions,
4510	add-file => add-syms, and load from alias to its own command.
4511
4512	* target.c (kill_or_be_killed, maybe_kill_then_attach,
4513	maybe_kill_then_create_inferior):  Default for attempts to start
4514	a process, if one is already running, is to ask about killing
4515	it and retry if yes.
4516	(upstack_create_inferior):  #if-0 it, strata obsolete it.
4517	(push_target, unpush_target, pop_target):  to_close() a target
4518	before unstacking it.
4519	(target_info):  Renamed from target_files_info.

4531	(REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
4532	MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
4533	REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW):  Float regs
4534	are now 10 byte extendeds, not 8 byte doubles.
4535	(FRAME_CHAIN_VALID):  Make this config-dependent, since it differs
4536	for nindy versus vxworks targets.  FIXME, this should possibly go
4537	in the target vector.
4538	(EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO):  Cache both
4539	frame_saved_regs and arg pointer with each frame.
4540	(FRAMELESS_FUNCTION_INVOCATION):  New leafproc support.
4541	(FRAME_ARGS_ADDRESS):  Use cached result.
4542	(FRAME_ARGS_ADDRESS_CORRECT):  New, avoids g14 guessing.

4545	(POP_FRAME):  Now works.
4546
4547	* tm-nindy960.h:  Break this off tm-i960.h.  NINDY-specific
4548	option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
4549	BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
4550	(ADDITIONAL_OPTION_HANDLER):  use target_load, not
4551	target_add_file.
4552
4553	* tm-vxworks960.h:  Break this off tm-i960.h.  VxGDB specific
4554	startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
4555
4556	* valarith.c (value_subscripted_rvalue):  Avoid handling
4557	floats and doubles specially; it gave alignment errors.  Lint.
4558
4559	* valops.c (value_of_variable, value_of_this):  Error if unknown
4560	value.
4561
4562	* valprint.c (print_floating):  Bcopy rather than pointer-deref,
4563	to avoid alignment problems.
4564	(value_print):  Handle unknown value address.
4565	(cplus_val_print):  Two args are ignored; remove them.  Change caller.
4566	(val_print):  Use unpack_long rather than pointer-deref.
4567
4568	* values.c:  Lint.
4569	(unpack_long, unpack_double):  Use bcopy rather than pointer-deref
4570	to avoid alignment problems.
4571	(value_being_returned):  Error if return value unknown.
4572	(set_return_value):  Add bogosity warning, FIXME.        *
4573
4574	* TODO:  A woman's work is never done.
4575
4576	* Makefile.dist:  Distribute REMOTE_OBS into tconfig files.
4577	Separate INCLUDE_CFLAGS for use with lint.  Add LINTFILES.
4578	Add ieee-float.o to OBS.
4579	* tconfig/{nindy960,vxworks68,vxworks960}:  Include the desired
4580	REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4581	* tconfig/i960:  FIXME.  Half-merge, produce warning if config'd.
4582
4583	Changes to generalize the VxWorks RPC protocol slightly, to handle
4584	i960 as well as 68000.
4585
4586	* vx-share/dbgRpcLib.h (VX_SOURCE_STEP):  Add.
4587	* vx-share/reg.h:  Produce i960 regs #ifdef I80960
4588	* vx-share/xdr_ptrace.c:  Skip FPA registers if 960.
4589	* vx-share/xdr_rdb.h:  Add SOURCE_STEP struct and xdr decl.
4590	* vx-share/xdr_rdb.c:  Add xdr_SOURCE_STEP routine.
4591	* vx-share/xdr_regs.c:  Add xdr_regs, xdr_fp_status, xdr_ext_fp
4592	for i960.  Change xdr_vectors to xdr_opaques for 68k registers,
4593	so they will move in target byte order rather than network
4594	byte order (happens to be the same).
4595
4596Mon Feb 25 03:41:44 1991  John Gilmore  (gnu at cygint.cygnus.com)
4597
4598	* tm-convex.h (END_OF_TEXT_DEFAULT):  Remove #if 0'd block.
4599
4600Sun Feb 24 00:55:53 1991  John Gilmore  (gnu at cygint.cygnus.com)
4601
4602	* am29k-pinsn.c,
4603	Add contribution lines to various files, showing where they
4604	came from.
4605
4606	* breakpoint.c (break_insn, check_break_insn_size,
4607	read_memory_nobpt):  Remove to mem-break.c.
4608
4609	* xm-*.h, param-no-tm.h, tm-29k.h, valprint.c:  Change BYTE_ORDER to
4610	HOST_BYTE_ORDER.
4611
4612	* tm-29k.h (STAB_REG_TO_REGNUM):  Warn user if symbol table
4613	entry has bad register number.  This change is not
4614	tested in this release, FIXME.
4615
4616	* frame.h:  Eliminate Frame_unknown in favor of a simple zero.
4617	tm-vax.h:  Ditto.
4618
4619	* value.h:  Force value's contents field to be aligned to hold
4620	at least a double or a long long (if supported).  This avoids
4621	doing bcopy's in and out of the contents field.
4622
4623	(step_1):  Avoid coredump under obscure circumstances when we
4624	have no frame.
4625
4626	* symtab.h (misc_info):  Add field to misc function vector for
4627	any kind of cached information the target code desires.  AMD
4628	29000 uses this to avoid repeating examine_function_prologue's.
4629
4630	* coffread.c:  Lint.  Remove static symfile, read_section_header.
4631	core.c (have_core_file_p):  Lint: remove.
4632	expprint.c (print_subexp):  Lint.
4633	infptrace.c, valops.c, valprint.c:  lint.
4634
4635	Roll in changes from vxgdb-5.0.1:
4636
4637	* symtab.h:  Comment byte order of each address class.  Add
4638	LOC_LOCAL_ARG for frame-relative args (960).
4639	expread.y:  Use LOC_LOCAL_ARG where LOC_ARG is used.
4640	symtab.c, symmisc.c:  ditto.
4641
4642	* infrun.c (init_wait_for_inferior):  Clear stop_signal.
4643
4644	* remote.c (remote_resume):  Error if resume with a signal.
4645
4646	* symfile.c (prim_record_misc_function):  Clear misc_info.
4647	(fill_in_vptr_fieldno):  Check stub type of arg.
4648
4649	* valops.c (value_cast):  Avoid looking up names of types whose
4650	name we don't know, to prevent coredump.  Sun CC produces typedef
4651	rtx and the name of *rtx is zero...
4652
4653Mon Feb 18 21:16:25 1991  John Gilmore  (gnu at cygint.cygnus.com)
4654
4655	Roll in changes from final AMD 29000 port (Tiemann).
4656
4657	tconfig/am29k:  Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4658	for ../include/a.out.encap.h.  This might not work now that BFD
4659	is separately compiled.  Instead, BFD support for encap will have
4660	to translate machine type 29k into the right COFF_MAGIC.
4661
4662	* infcmd.c: Remove references to inferior_pid that aren't used
4663	in actual ptrace calls; use target_has_execution, etc.
4664	(have_inferior_p):  Remove function.
4665	(program_info):  Print target info rather than "process number";
4666	avoid gratuitous messages unless from_tty.
4667	(run_stack_dummy, finish_command):  Set proceed_to_finish.
4668	infrun.c: Remove inferior_pid refs.  Decl & init proceed_to_finish.
4669	main.c:  Lint.  Lose have_inferior_p().
4670	inferior.h (have_inferior_p):  Remove, lint.
4671	(proceed_to_finish):  Add flag to ask that all regs be saved
4672	by normal_stop, for the few commands that need it, speeding up
4673	serial I/O.  Add comments to stop_registers.
4674
4675	* remote-eb.c:  Remove newline from breakpoint message we grep
4676	for.  Never time out when running the user program.
4677
4678
4679
4680Wed Feb 13 15:34:40 1991  John Gilmore  (gnu at cygint.cygnus.com)
4681
4682	Roll in changes from vxgdb-5.0.1:
4683
4684	* dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4685	symbol in its raw form, we are processing an unlinked ".o" file.
4686	See if the target environment has assigned it an address, using
4687	target_lookup_symbol (VxWorks does), and enter it into the symtab
4688	that way.
4689
4690	* tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID):  Override usual
4691	68k versions for a simpler version that assumes zero FP at bottom.
4692	Fixes bug of truncated stack reports.
4693
4694	* target.h (target_lookup_symbol):  Define this routine's args
4695	and result, finally.
4696
4697	* target.c (nosymbol):  Default routine for target_lookup_symbol.
4698	(target_default):  Default lookup_symbol and call_function too.
4699	(files_info):  Only print has_all_memory warning if a non-dummy
4700	target follows.
4701
4702	* remote-vx.c (vx_read_register, vx_convert_to_virtual,
4703	vx_convert_from_virtual): If target does not have floating point,
4704	zero register "values", and avoid doing cross-net conversions.
4705	(vx_lookup_symbol):  Rename net_lookup_symbol, add to vectors.
4706	(vx_open):  Rearrange code that attaches to target and reads
4707	symbols for all loaded modules, to work if some of the modules
4708	are not accessible.  Add symbol_stub() and add_symbol_stub()
4709	as callbacks from catch_errors().  Allow connect attempt to be
4710	interrupted painlessly with ^C (FIXME, there are still some bugs
4711	if the interrupt happens during symbol reading.).  Print
4712	final message with puts_filtered, since symbol messages are
4713	now filtered too.
4714
4715	Misc cleanup:
4716
4717	* main.c (catch_errors):  Only print errstring if non-null.
4718	(command_loop):  Avoid an ioctl per command to test ISATTY.
4719
4720	* remote-vx.c (net_load):  make static; avoid sophomoric msg.
4721	(vx_xfer_memory):  Return correct result!
4722	(vx_files_info):  Indicate whether target has float or not.
4723	(vx_lookup_symbol):  Complain, not error, if target gone.
4724	(vx_open):  Print "Connected" msg before disabling immediate-quit.
4725	[FIXME:  lookup_symbol and vx_open changes need testing.]
4726
4727	target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4728	tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4729	contributor lines and update copyrights to 1991.
4730
4731	Changes from an attempted H-PUX host port:
4732
4733	* infptrace.c (PT_ATTACH, PT_DETACH):  Handle HP/UX, which
4734	defines PT_ATTACH and PT_DETACH but not PT_KILL.
4735	* remote-eb.c (eb_open):  Misplaced endif kills sysv H/PUX.
4736	* remote-vx.c: include <sys/time.h> for HPUX.
4737	* hp300hpux-xdep.c (fetch_core_registers):  Rewrite old
4738	"core_file_command" routine to BFD regime.  May not work yet.
4739
4740	Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4741
4742	* xgdb.c: Replace X10 version with some VJ version.
4743	(FIXME:  Its copyright assignment is not on record.)
4744	* xgdb.c:  Update include files to X11R4 (Xaw crud).
4745	(xgdb_display_source, create_text_widget): fix call to
4746	get_filename_and_charpos.  Rewack source window stuff for X11R4
4747	(gleaned from include files, and "nm's" of binary libraries, since
4748	I had no doc available).
4749	(append_selection, append_selection_word): Disable with FIXME
4750	since R4 changed interface here.
4751	(create_buttons):  Add back the old set of buttons.
4752	(xgdb_create_window):  Fix call to XtInitialize (&argc not argc).
4753
4754	* Makefile.dist (xgdb, xgdb-init.c):  Update for X11R4 on Suns.
4755	Roll VERSION to 3.94 (not yet final though).
4756
4757Sat Feb  9 09:46:25 1991  John Gilmore  (gnu at cygint.cygnus.com)
4758
4759	* obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4760	obstack_int_grow, obstack_int_grow_fast):  Eliminate
4761	cast on left of assignment, which gives MIPS cc fits and is
4762	not Standard C.
4763
4764	* sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4765	F_ALIAS.  Use printf, not fprintf, when not passing a file
4766	pointer...
4767	(compare_opcodes): Check that identical instructions have
4768	identical opcodes, complain otherwise.
4769
4770	* sparc-opcode.h (st %fsr):  Fix opcode "lose" mask.  This
4771	was reported by Roland McGrath.
4772	(unimp): Only match if exactly zero instruction.  (Roland)
4773	(branches and traps):  Generate all variations of these
4774	instructions with macros, based on a single call that defines
4775	each condition name and its binary representation.
4776	(set):  Turn on alias bit, to avoid test in sparc-pinsn.c.
4777
4778	* valprint.c (val_print_fields):  Take, and use, format parameter.
4779	This means that "p/x struct" again prints the elements in the
4780	desired format.  Changed callers.
4781
4782	* stack.c (frame_info):  Use filtered output, and indicate wrap
4783	points.  Remove kludgy formatting designed to avoid line wrap.
4784
4785	* utils.c (wrap_here):  If the line is already full (because
4786	we had printed a long indent or long wrapped string), do an
4787	immediate newline-and-indent.
4788
4789	* m68k-pinsn.c (print_insn_arg): Bugfix from
4790	ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4791	instruction is incorrectly disassembled as bkpt #8.
4792
4793	* dbxread.c (end_psymtab): Bugfix from Peter Schauer
4794	<pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4795	breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4796	and then will dump core (sometimes). I traced it back to an
4797	uninitialized symfile_name in psymtab_to_symtab.
4798	(const_vol_complaint):  Add quotes to message.
4799	(define_symbol):  Only believe line number if gcc_compiled.
4800	Avoid allocating symbol if we will not return it.
4801
4802	Add target strata support so that newly established targets go
4803	into their right place in the target stack (e.g. a new exec file
4804	doesn't wipe out the ability to access the running process).
4805
4806	* target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4807	remote-nindy.c, remote-vx.c, remote.c, target.c:  Add to_stratum
4808	and initialize it properly in all the targets.
4809
4810	* target.h:  Document strata.  Change return type of push_target.
4811
4812	* target.c (nomemory):  new function for dummy memory access.
4813	(tcomplain):  Rename complain, now also used in symfile.c.
4814	(push_target):  Push targets within strata.  New return value shows
4815	whether new target is on top of stack or not.  Always keep dummy
4816	target on stack.
4817	(target_files_info):  Ignore dummy target.
4818
4819	* core.c (core_open):  Warn user, and skip accessing file, if the
4820	core target is not the topmost target in the stack.
4821	* remote-nindy.c (nindy_create_inferior):  Avoid unpush_target, now
4822	already handled.
4823
4824	* remote-vx.c:  Remove vx_prepare_to_store from vxworks memory
4825	target_ops, it doesn't belong there since we have no regs there.
4826	Change name of target from machine => memory to clarify.
4827
4828Thu Feb  7 16:32:09 1991  John Gilmore  (gnu at spiff.cygnus.com)
4829
4830	* Freeze version 3.93 for release.
4831
4832	* Makefile.dist:  Handle vx-share and nindy-share subdirs
4833	properly when building gdb.tar.Z.
4834
4835	* symtab.c:  lint; add no_symtab_msg to consolidate the messages
4836	printed in various places, so I could change just one copy.
4837
4838	* dbxread.c, coffread.c:  Change references to bfd->iostream
4839	to cast to FILE *, now that BFD avoids needing types defined
4840	in other header files.
4841
4842Tue Feb  5 21:39:35 1991  John Gilmore  (gnu at cygint.cygnus.com)
4843
4844	* command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4845	infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4846	sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4847	(actually gcc -Wall).
4848
4849	* dbxread.c:  Remove first_global_sym, last_global_sym, since
4850	they are never referenced.
4851
4852	* defs.h (baud_rate):  Declare.
4853	main.c: Define it, and add the -b option to set it.
4854
4855	* gdb-int.texinfo:  Add text on how to define a new host or target
4856	architecture, prompted by Per Bothner's questions about MIPS
4857	support.
4858
4859	* gdb.texinfo:  Document "complaints".  Change doc of -q since
4860	gdb no longer prints the copyright and blurb if you specify a file
4861	name to be debugged (just like Emacs).  Add doc for Nindy-specific
4862	command line flags for specifying target serial port and such.
4863	Update copyright to 1991.
4864
4865	* gdbcore.h:  Remove a large mass of now-useless crud, since BFD
4866	has taken over for us the job of ripping up executable files.  The
4867	crud caused Per Bothner's port to not compile.
4868
4869	* infrun.c (normal_stop):  Avoid printing "Program exited
4870	normally" if we are in batch mode.  This allows a GDB which
4871	executes a program on a target system, to behave like a Unix
4872	command (input from stdin, output to stdout, no extraneous
4873	output).
4874
4875	* main.c (main):  Allow additional machine-dependent command line
4876	options to be specified with the ADDITIONAL_OPTIONS,
4877	ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4878	ADDITIONAL_OPTION_HANDLER macros.  Also allow machine-dependent
4879	processing to occur just before the main loop with
4880	BEFORE_MAIN_LOOP_HOOK.
4881	(main):  If a "core file" argument is specified, and it is not a
4882	core file, try it as a process ID to attach.
4883	(symbol_completion_function):  Attempt to cope with
4884	"show screen-" TAB, not very successfully.  This needs more work,
4885	FIXME.
4886	(batch_file):  New function, returns whether we are reading
4887	commands from an interactive tty on stdin, or from somewhere else.
4888	Called by normal_stop since it doesn't get from_tty passed down
4889	to it like many commands do.
4890
4891	* remote-nindy.c:  Handle command line options for nindy
4892	connection.
4893	(nindy_before_main_loop):  Prompt user for tty name if they
4894	don't specify it before getting to the interactive command loop.
4895
4896	* tm-i960.c:  Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4897	and -r command line options.  Also add hook before main loop
4898	to make it easy to specify a tty.
4899
4900	* TODO:  More things to do, one done.
4901
4902Mon Feb  4 23:57:39 1991  John Gilmore and Mike Tiemann  (at cygint.cygnus.com)
4903
4904	* dbxread.c:  Make complaint() calls pass pointer, not struct.
4905	Add complaints about badly formatted C++ type information
4906	(const/volatile indicator, and parse errors resulting in
4907	error_type).  Fix C++ virtual member fn comment.
4908	(read_struct_type):  Avoid bumping pointer if we got a parse
4909	error; this prevents our walking beyond the end of a string.
4910	Terminate loop on null char as well as semicolon.
4911	(process_one_symbol):  Fix the LBRAC fix so that it uses the
4912	last previous SLINE, FUN, or SO record's PC address.  C++ debug
4913	symbols did not have SLINE records in a useful order compared
4914	to the LBRAC records.
4915	(define_symbol):  Handle "catch" records.
4916
4917	* symtab.c (check_stub_type):  Added new complain
4918	`stub_noname_complain' and added a consistency check to
4919	keep the debugger from crashing when finishing from an
4920	exception frame.  A real fix will be needed later.
4921
4922Sat Feb  2 10:43:05 1991  John Gilmore  (gnu at cygint.cygnus.com)
4923
4924	* infcmd.c (attach_command):  Make global.
4925
4926	* Makefile.dist (REMOTE_OBS):  Make these compile by default,
4927	but make them easy to comment out.  Perhaps later they should
4928	be enabled by what CPU you configure for?  FIXME.
4929	(VERSION):  Roll to 3.93.
4930	(pinsn.o):  Remove rule for obsolete file.
4931	(dbxread.o,coffread.o,mipsread.o):  Use ${srcdir} explicitly.
4932
4933	Run down a problem that manifested by printing the wrong function
4934	name in stack traces of read_ofile_symtab.  Turned out that the
4935	problem was the SunOS 4.1.1 (and previous) C compiler outputs
4936	the LBRAC symbol with an address in the *data* segment, which
4937	blew our binary search through the blocks.
4938
4939	* dbxread.c: Use the complain() facility consistently to bitch
4940	about problems in the symbol file we are reading.
4941	(finish_block):  Add code to check the nesting of the blocks;
4942	complain and Procrust them to fit if wrong.
4943	(make_blockvector):  Check the order of the blocks, complain
4944	[but don't cope] if wrong.
4945	(process_one_symbol):  ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4946	symbols to be sure their PC value is greater than the last SLINE
4947	(line number) symbol we've seen, complaining and adopting the
4948	SLINE PC value if wrong.
4949
4950	* symfile.h (struct complaint, complaint_root, complain,
4951	clear_complaints):  Add.
4952	* symfile.c (complain, complaint_root, clear_complaints):  Add
4953	facility to deal with non-fatal complaints and to regularize their
4954	suppression.
4955	(symbol_file_add):  Clear complaint counters to allow new complaints.
4956	(initialize_symfile):  Add 'set complaints' and 'show complaints'.
4957
4958	* dbxread.c (dbx_symfile_read):  Remember the address and size
4959	of the string table for the main symbol file, so we won't read it
4960	more than once.
4961	(dbx_psymtab_to_symtab):  Fix the check for main symbol file,
4962	to avoid reading the string table yet again.  Lint.
4963	(throughout):  Improve filtered output, including word wrap.
4964	(read_range_type):  Improve Bothner's fix to handle other types too.
4965
4966	* utils.c:  Improve line wrap implementation.  Handle unlimited
4967	width by making chars_per_line unsigned.
4968	(puts_filtered):  New, easy, function.
4969
4970	* defs.h (puts_filtered):  add.
4971
4972	* mipsread.c (compare_symbols, sort_symtab):  Remove these fns,
4973	call the identical sort_symtab_syms() in symfile.c instead.
4974
4975	* expread.y:  Suggest the `file' command rather than `symbol-file'.
4976
4977	* command.h (enum var_types):  Add zinteger for seroable
4978	unsigned integer.
4979	* command.c (do_setshow_command):  Handle var_zinteger.  Restructure
4980	nested if's into a switch.
4981
4982	* breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4983	we did not stop because of a breakpoint (it must have been for
4984	some other reason, like a "stepi"), so don't print anything.
4985
4986	* symtab.c: Include <sys/types.h> all the time.  Now that BFD
4987	doesn't include <sys/types.h>, old SunOS's require it for
4988	<sys/stat.h>.
4989
4990Sat Feb  2 10:39:15 1991  Per Bothner  (bothner@cs.wisc.edu)
4991
4992	A test port of gdb-3.92.6 to the Sony NEWS.
4993
4994	* Makefile.dist
4995	Don't normally link in remote- or vx stuff.
4996	Some of it doesn't compile, and it wastes space for 99%	of the users.
4997	Remove reference to no-longer-used HAVE_VPRINTF.
4998	Fixed BFD_DEP typo to BFD_DIR.
4999	* dbxread.c
5000	Fix cast in arg to bfd_h_getlong.
5001	Make char *prefix be const.
5002	Fix how certain range types are mapped into builtin unsigned int types.
5003	* infrun.c
5004	Remove 2 #includes. They cause errors (on Sony, at least),
5005	and aren't needed (they wern't in earlier versions).
5006	* printcmd.c
5007	print_address_symbolic should never demangle labels
5008	(since it prints *assembler-level* labels).
5009
5010	       [This was superseded by the change to printcmd below.]
5011
5012	* utils.c
5013	Add some "volatile" return types to avoid warnings.
5014	If MISSING_VPRINTF add vprintf function and not just macro
5015	(since vprintf is used in printcmd.c).
5016	* valprint.c
5017	Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
5018	(The latter isn't grokked by some PCC-based compilers.)
5019
5020	     [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
5021
5022	Make chunk size of dont_print_obstack 32*4 instead of default 4096.
5023	* nindy-share/coffstrip.c
5024	Added some forward declarations (otherwise, gcc complains
5025	about implicit extern redefined as static).
5026
5027Sun Jan 20 02:38:19 1991  John Gilmore  (gnu at cygint.cygnus.com)
5028
5029	Changes inspired by Per Bothner:
5030	* printcmd.c (print_address_symbolic):  Take additional parameter
5031	specifying whether to demangle.
5032	(print_address):  Pass in asm_demangle to control demangling.
5033	(print_address_demangle):  New fn, takes explicit arg to control
5034	demangling.
5035	* utils.c:  Add new vars demangle and asm_demangle, and let them
5036	be set and shown.
5037	(fputs_demangled):  If !demangle, just print the argument.
5038	(fprint_symbol):  If !demangle, just print raw symbol.
5039	* valprint.c (val_print):  Call print_address_demangle rather than
5040	print_address, to cause demangling to depend on the global
5041	rather than assembler-level demangling setting.
5042	* WHATS.NEW, gdb.texinfo:  Document.
5043
5044	* main.c (show_command):  Show all settings if no arg.
5045	(initialize_main):  Make "info set" the same as naked "show".
5046	* command.c (cmd_show_list):  Handle prefix commands in the
5047	list, and print the name of the setting as well as its English
5048	description and value.
5049
5050	Allow gdb functions to specify where a line should wrap if it
5051	exceeds the size of a terminal line.  Use it to make the output
5052	prettier.
5053	* utils.c (set_screen_width_command):  New fn, mallocs a buffer
5054	of the right size when screen width changes.
5055	(set_screensize_command, screensize_info):  Remove #if 0'd fns.
5056	(wrap_here):  New fn, indicates a point in the output where we
5057	should wrap the line rather than just letting it overflow at a
5058	random place.
5059	(fputs_filtered):  Implement wrapping.
5060	(n_spaces):  New fn, returns a pointer to N spaces.
5061	(print_spaces_filtered):  Use n_spaces.
5062	* defs.h (n_spaces):  Declare.
5063	* stack.c (print_frame_info):  Wrap with 4-space indent after
5064	fn name and before filename and line number.
5065	* printcmd.c (print_frame_args):  Wrap with 4-space indent
5066	before each argument name is printed.
5067	* valprint.c (value_print):  Wrap with no indentation before
5068	each repetition.
5069	(val_print_fields):  Wrap with indentation relative to nesting
5070	level before each field name.
5071	(val_print):  Wrap with nesting indentation before array elements.
5072	* command.c (do_setshow_command):  Avoid extra newlines,
5073	wrap with 4-space indent around values printed, end with period.
5074	* WHATS.NEW, gdb.texinfo, gdb-int.texinfo:  Document.
5075
5076	* breakpoint.c (breakpoint_1):  Implement addressprint for
5077	"info breakpoints" display.  Change file name and line number
5078	format to " at file:nnn" rather than " (file line nnn)".
5079	* gdb.texinfo:  Document.

5082Fri Jan 18 07:21:25 1991  John Gilmore  (gnu at cygint.cygnus.com)
5083
5084	Frozen for gdb-3.92.6 release.
5085
5086	README, WHATS.NEW:  Update for 3.92.6 release.
5087
5088	tconfig/{altos, i386v, i386v32, m88k, umax}:  Eliminate
5089	coffread.o from configs since it is now built by default.
5090	tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
5091	i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
5092	pyramid, symmetry, vax, vxworks68}:  Eliminate dbxread.o
5093	from configs since it is now built by default.
5094
5095	Makefile.dist: Update for release 3.92.6.  Handle files that
5096	have been moved to ../include, ../getopt, or ../bfd.  Add
5097	saber.suppress and tests directory.  Add config.status to
5098	the release (it will say "none").
5099
5100	coredep.c:  Minor formatting fixes.
5101
5102	These changes were made in early December but only checked in now:
5103	* nindy-share/Onindy.c, nindy-share/coffstrip.c,
5104	nindy-share/nindy.c:  lint
5105	* nindy-share/nindy.c (ninStopWhy):  Don't byteswap the
5106	register values coming back from the target; we store values
5107	in target byte order everywhere.
5108
5109Wed Jan 16 19:01:37 1991  John Gilmore  (gnu at cygint.cygnus.com)
5110
5111	* am29k-opcode.h, am29k-pinsn.c:  Add 29050 opcodes.
5112
5113	* valprint.c (cplus_val_print, val_print_fields):  New functions,
5114	which print C++ objects.  They conspire to avoid printing a
5115	virtual base class more than once, following all the twists and
5116	turns of C++ virtual base rules.
5117	(val_print):  Call the above rather than do it by hand.
5118
5119	* symfile.c (symbol_file_add):  Only reset symfile_mtime for main
5120	symbol file, not for added files like shared libs.  This really
5121	needs to be generalized to a timestamp per file.
5122
5123	* core.c (cleanup_core):  Avoid coredump if no core file.
5124
5125	* config.gdb:  Accept -host or -target in place of +host or
5126	+target.
5127
5128	* coffread.c (find_linenos):  Avoid desupported BFD interface
5129	to line numbers.  We still read them manually rather than using
5130	BFD's "generic" features.
5131
5132	* gdbrc.tex, threecol.tex:  Add GDB reference card and its
5133	formatting code.
5134	Makefile.dist:  Add refcard to OTHERS list for creating tar files.
5135
5136	* Makefile.dist:  Eliminate use of $< in explicit targets.
5137
5138	* readline/Makefile:  Use $< rather than $*.c, which does not
5139	include the VPATH in GNU Make.
5140
5141	* tconfig/i960-bout, tconfig/i960-coff:  These are identical
5142	copies of tconfig/i960, added for global configuration
5143	compatability.  All i960 versions can read both coff and b.out.
5144
5145	* tm-88k.h:  Fix multiline macro that lacked \'s.  Remove
5146	COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
5147	automaticaly.
5148
5149	* TODO:  Think of more things to do.
5150
5151Wed Jan  2 19:09:29 1991  John Gilmore  (gnu at spiff.cygnus.com)
5152
5153	tconfig/{am29k,i960,sun2*,sun3*,sun4*}:  Eliminate config
5154	of sdb versus dbx debug symbols.  Add kludge for 68881 80-bit to
5155	64-bit float conversion.
5156
5157	tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3:  Make
5158	equivalent to sun?os4 so global config works.
5159
5160Wed Jan  2 18:20:51 1991  John Gilmore  (gnu at spiff.cygnus.com)
5161
5162	Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
5163
5164	* main.c:  Only declare linesize once; declare pagesize not at
5165	all, since it is never used.
5166	(main):  Clear newly allocated line before it is used.
