1Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint) 2 3 Further stabilization for the Intel 960. 4 5 * Makefile.dist: Parameterize the location of the "include" 6 and "bfd" directories, as well as "getopt". Add symfile.c. 7 Link in both dbxread and coffread. Fix up "make depend" to 8 rewack the locations of include, bfd, and getopt in its output. 9 10 * README: Document moving include files, improve some of 11 the other doc. 12 13 * coffread.c: Move common code out to symfile.c. Change 14 symbol_file_command style interface to use new *_symfile_init 15 and *_symfile_read interface under BFD. Use BFD internal 16 info to locate line table, symbols, etc. 17 18 * core.c (core_fetch_registers): Rename to get_core_registers 19 to avoid confusion with fetch_core_registers. 20 (register_addr): Move to coredep.c, which is already machine 21 dependent. This leaves core.c pretty clean of dependencies. 22 23 * coredep.c (register_addr): Accept this routine from core.c. 24 25 * dbxread.c: Move common code (with coffread.c, etc) into new 26 symfile.c. Each psymtab now contains a pointer to the 27 format-dependent function that knows how to read it in. Make 28 some things static. 29 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2. 30 (process_one_symbol): Add code to complain about a "compiler bug 31 we muzzle here", if we actually see it. 32 33 * eval.c (evaluate_subexp): Insert missing "break" statements 34 in code that determines whether a variable is an lvalue in 35 memory, register, or whatever. I detected this via a compiler 36 bug in which it *almost* mashed out the whole switch statement. 37 38 * gdb-int.texinfo: Add minor sections on configuring gdb for 39 release, and about the README file. 40 41 * infcmd.c (registers_info): Fix formatting somewhat. Still 42 not as pretty as before, but it handles byte swapping. 43 44 * remote-nindy.c: If data cache routines are interrupted while 45 waiting for the remote end, be sure that any uninitialized cache 46 blocks are on the free list, not on the valid list! 47 48 * symfile.h: Flesh out this header file with all the various 49 routines and variables that have been merged in from dbxread.c 50 coffread.c, and symtab.c to symfile.c. 51 52 * symfile.c: New file, containing code common to dbxread.c, 53 coffread.c, and some code from symtab.c. All generic code for 54 reading symbol files should be in here now. 55 (unrecord_misc_function): Remove unused function. 56 57 * symtab.h: Remove file-reading things to symfile.h. 58 59 * symtab.c: Remove file-reading things to symfile.c. 60 61 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL 62 to decode i960 fault types. 63 64 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c, 65 target.c: Change type of the "resume" function from int to void, 66 since its result was never used. 67 68Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint) 69 70 * main.c: Replace "stupid" with "caution"; you now "set caution 71 on or off". 72 73 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format 74 75 * infcmd.c (do_registers_info): Call val_print to deal with the 76 byte order of the registers being printed. FIXME, this makes 77 the formatting of the output uglier. 78 79 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is 80 defined, call it for signals the debugger doesn't itself use. 81 The i960 uses this for more detailed fault information. 82 83 * remote.c (remote_open): If arg is null, print help rather than 84 dumping core. 85 86 * sparc-xdep.c (register_valid): Avoid declaring size, since 87 various modules will think of various sizes depending on the 88 architecture of their tm-file. FIXME, we need protection against 89 actually entering one of those modules, which would clobber 90 storage if not for the target architecture compiled into gdb. 91 92 * stack.c (up_command, down_command): Always print the frame 93 you arrive at. 94 (up_silently_command, down_silently_command): New commands 95 for use in scripts. 96 97 * i960-pinsn.c (reg), i960-tdep.c: Lint. 98 99 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes 100 more parameters than it used to. 101 102 * findvar.c (registers): Increase slop to 256 bytes, which should 103 protect us against even most RISC machines with large register 104 sets. 105 (locate_var_value): Move declaration inside related ifdef. 106 107 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP 108 throughout, to avoid throwing away buffered input from the board. 109 (nindy_wait): Supply_register takes addr_of_value, not value. 110 (i960_print_fault): Renamed from i80960_fault. 111 (nindy_fetch_registers): Avoid have_regs stuff, just get them. 112 (nindy_store_registers): Avoid regs_changed stuff, just stuff 113 them. 114 (nindy_create_inferior): Don't bother to write PC_REGNUM since 115 we can set the PC in the call to proceed(). Unpush nindy_ops 116 before pushing it on top, to avoid message to user. Eliminate 117 commentary from Unix machines that just misleads here. 118 (reset_command): Fix error message to suggest target command. 119 120Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint) 121 122 Release 3.92.5 as frozen. 123 124 Stabilize the merged release...with help from lint, Saber C, 125 gcc -W, etc. 126 127 Everywhere: Add include files needed to declare return types 128 of functions called. 129 130 * gdb.texinfo: Roland Pesch is documenting gdb, glory be! 131 132 * breakpoint.h: Add undeclared breakpoint functions, and some 133 functions for display handling since I couldn't think of a better 134 .h to put them in. 135 136 * breakpoint.c (insert_breakpoints): Make code for disabling 137 shared library bkpts more likely to work. It's used when we 138 rerun a program and stop before the shared library has been 139 mapped in. 140 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int, 141 cast from pointer, so it squeezes through catch_errors. 142 (bpstat_stop_status): Fix logic broken some time ago. We now 143 always create a bpstat if the stop address matches a breakpoint, 144 even if we don't stop there -- just like the old code used to do 145 before I got my fingers into it (sigh). 146 (breakpoint_1): Print "ignore count" after "stop only if" 147 condition, since that's how it actually works. 148 (mention): Handle watchpoints as well as breakpoints. 149 (watch_command): use set_raw_breakpoint and mention to do most 150 of the work (and initialize all the fields!). Only pass one 151 arg to parse_c_expression, since that's all it takes. 152 153 * command.c (not_just_help_class_command): Rename arg to args 154 since we ignore "unused argument" warnings on vars named "args". 155 inflow.c (child_terminal_info): ditto. 156 infptrace.c (kill_inferior): ditto 157 main.c (catch_errors, version_info, quit_command, pwd_command, 158 source_command, dump_me_command, editing_info, 159 set_history_size_command, set_history, show_history, 160 set_verbose): ditto 161 stack.c (locals_info): ditto 162 target.c (target_files_info): ditto 163 valprint.c (set_input_radix, set_output_radix): ditto 164 165 * core.c: Remove old variables for handling core and exec file 166 sections (data_start, data_end, stack_start, stack_end, 167 reg_stack_start, reg_stack_end, reg_stack_offset, text_start, 168 text_end, exec_data_start, exec_data_end, text_offset, 169 exec_data_offset, data_offset, stack_offset). They're 170 superseded the more general build_section_table and 171 xfer_memory. 172 (get_exec_file): Mention the `file' command. 173 (read_memory_check): Rename to memory_error, and only call it 174 in the case of an actual error. 175 (read_memory, write_memory): call memory_error. 176 (core_fetch_registers): Register section name is ".reg". 177 178 coredep.c: Remove a bunch of crud now that all this file does 179 is pull the registers out of a core file. 180 (fetch_core_registers): Rewrite to actually work, I hope. 181 182 dbxread.c: Use a.out.gnu.h, not system a.out, now. 183 Replace index() with strchr(). Remove all the pre-BFD macro 184 definitions for accessing the symbol file. 185 (struct dbx_symfile_info): Encapsulate the information that 186 dbx_symfile_init needs to pass to dbx_symfile_read in this 187 struct. 188 189 (dbx_new_init, dbx_symfile_init, dbx_symfile_read, 190 dbx_symfile_discard): Rearrange symbol file reading to divide 191 the format-specific part from the format-independent part, 192 leaving the format-independent part such as file name expansion 193 and opening in symtab.c. This replaces 194 partial_symbol_file_open and partial_symbol_file_read. 195 Symbol_file_read, add_file, add_file_target_command, 196 add_file_addr_command move to symtab.c. Pass an explicit 197 "mainline" flag for when reading the main symbol table, rather 198 than relying on the offset address to be zero or nonzero. 199 200 (dbx_symfile_read): Don't allow void *'s to be printed as 201 typedefs. 202 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols. 203 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than 204 macro" debug version really work. 205 (read_dbx_symtab): Remove unref'd parameter inclink. 206 Avoid swapping N_SLINE symbols, for speed. 207 Merge N_TEXT!N_EXT case with the other external symbol 208 definitions' case. Add comments. 209 (start_psymtab): Allocate the symfile name in the psymtab on 210 the psymbol_obstack, rather than using the caller's storage. 211 (end_psymtab): Only allocate a dependencies list if there are 212 more than zero. 213 (psymtab_to_symtab_2): Use BFD when reopening file to read 214 its symbols for real. 215 (read_struct_type): Add FIXME comments where it needs work 216 for C++ bogosity. 217 (read_huge_number): Add FIXME about overflows. 218 (read_range_type): Add FIXME about comparing a long to 1<<32. 219 220 * coffread.c: Minor changes to move things closer to the new 221 regime with symtab.c and dbxread.c Major work is still needed 222 here. 223 224 * exec.c (exec_file_command): Remove old variables (see core.c 225 above). 226 (xfer_memory): If memory transfer is right at the end of a 227 section, don't lose. 228 229 * findvar.c (get_saved_register): If value is in a real 230 register, LVAL is lval_register, not lval_memory. 231 232 frame.h: Declare print_sel_frame and record_selected_frame. 233 234 gdb-int.texinfo: New file, for GDB internals documentation. 235 Very simple, unformatted doc of cleanups is there for now. 236 237 gdbcore.h: Remove obsolete variables that described a.out 238 section addresses and offsets. (See core.c above.) 239 Declare fetch_core_registers and registers_fetched. 240 241 getopt.c: Declare char *alloca(); even on SPARC. 242 243 infcmd.c (run_command): Call target_kill rather than 244 kill_inferior. 245 (step_command, next_command, stepi_command, nexti_command): 246 Declare from_tty parameter even though we don't use it. 247 (run_stack_dummy): argument BUFFER is a char array, not 248 a pointer to REGISTER_TYPE. 249 (finish_command): using_struct_return needed a value *, 250 not a struct symbol *. 251 252 * infptrace.c (child_xfer_memory): To avoid dependency on 253 where sections are in memory, try PT_WRITE_D and if that fails, 254 try PT_WRITE_I. Most Unixes don't care which you use. 255 256 * infrun.c (step_resume_break_shadow): Change to array to 257 match other breakpoint shadow storage. 258 (clear_proceed_status): Pass address of bpstat to 259 bpstat_clear, not the bpstat itself. 260 (child_create_inferior): FIXME comment about if the child 261 exits. 262 (start_inferior): Remove old function. 263 (child_open): Use target_kill rather than kill_inferior. 264 (wait_for_inferior): Ditto. 265 (insert_step_breakpoint, remote_step_breakpoint): Use 266 new step_resume_break_shadow. 267 268 * inftarg.c (child_wait): If all child processes die, 269 pretend that the one being waited for exited with signal 42. 270 271 * main.c (command_line_input): When scanning for comments, 272 don't coredump on unclosed quotes. 273 (quit_command): Use target_kill rther than kill_inferior. 274 (_initialize_main): Rename class_user from "user" to 275 "user-defined". 276 277 * printcmd.c (print_command_1): Initialize "fmt" if no format 278 is specified by the user. 279 (print_frame_args): Only add to args_printed if we are 280 actually fetching args from the stack (avoiding undefined 281 arg_size). 282 (_initialize_printcmd): Remove bogus \{ from string. 283 284 * remote-eb.c (eb_open): Avoid coredump on no argument. 285 286 * remote-nindy.c: Bring out of Intel environment into new 287 target environment. Remove all conditional compilation on 288 I80960. Massive hacking throughout. 289 (nindy_xfer_inferior_memory): New routine stolen from 290 infptrace.c. 291 (nindy_create_inferior): New routine pieced together, probably 292 not quite working yet. 293 (nindy_ops): New target_ops struct for nindy. 294 295 * remote-vx.c: Use write_memory rather than target_write_memory 296 to get error checking. 297 (vx_add_file_command, vx_open): Use symbol_file_add rather than 298 add_file. 299 (vx_create_inferior): Use target_terminal_ours... 300 301 * signame.c (_initialize_signame): Always initialize, since 302 we need the table for things other than psignal. 303 304 * solib.c (solib_add): Use symbol_file_add, not add_file. 305 (solib_address): Return boolean result rather than struct 306 pointer which nobody else knows the type of. 307 308 * sparc-tdep.c, valops.c: Use write_memory rather than 309 target_write_memory, to get error checking. 310 311 * stack.c (locals_info, catch_info, args_info, 312 get_selected_block, frame_command, up_command): Use 313 target_has_stack, rather than have_inferior_p or 314 have_core_file_p. 315 316 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime. 317 318 * symfile.h: New file, defining the interface between the 319 generic and object-file-specific symbol reading code. 320 321 * symtab.c: Move generic symbol-reading interface to symtab.c, 322 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns 323 table to map BFD targets to symbol-reading modules in GDB. 324 Change index to strchr. 325 (lookup_struct_elt_type): Use error() rather than hand-made 326 simulations thereof. 327 (lookup_partial_symbol): Speedup slightly when length == 0. 328 (symbol_file_add): New function. 329 (symbol_file_command): Call it. 330 (symfile_open, symfile_init): New function. 331 (add_file_target_command, add_file_addr_command): moved from 332 dbxread.c. 333 334 * target.c (target_command): use target_kill. 335 336 * target.h (target_files_info): Don't declare, never called 337 from outside. 338 339 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include 340 files to determine stack end address. 341 342 * valarith.c (value_x_binop, value_x_unop): Change error message 343 to be more useful. Pass proper argument to value_struct_elt. 344 345 * valops.c (value_assign): FIXME comment that long long 346 bitfields will break here. 347 348 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c. 349 Update `make saber_gdb' to work better. 350 351 * TODO: A woman's work is never done. 352 353 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c, 354 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c, 355 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c, 356 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h 357 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c, 358 valops.c, valprint.c, exec.c: Lint. 359 360 361Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com) 362 363 Continuing Intel 960 port merge of GDB. 364 365 * Makefile.dist: Merge i960 "nindy-share" files. Rename 366 malloc.h to gmalloc.h to avoid name conflicts in /usr/include. 367 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c. 368 Wack over "make depend" so it handles files in subdirectories 369 vx-share, nindy-share, bfd, and in the current directory. 370 371 * blockframe.c (get_prev_frame_info): Remove fatal error 372 if stack not defined. 373 374 * core.c (core_open, core_detach): New functions that handle 375 the old "core-file" command as "target core" and "detach" instead. 376 (core_file_command): Call them. 377 (core_xfer_memory): Use common routine xfer_memory. 378 379 * dbxread.c: Include a.out.gnu.h, not system a.out.h. 380 dbxread now uses bfd for everything but symbol reading itself. 381 BFD internals are used to drag out the relevant file offsets. 382 (partial_symbol_file_open): Change args all around for BFD. 383 384 * symtab.c: Rename "value" to "val" everywhere, so we can 385 #include "value.h". 386 (symbol_file_command): New command, moved from dbxread.c 387 and coffread.c. It uses BFD to read the file, then vectors 388 based on its type, to dbx or coff symbol readers. 389 * symtab.h: Extern a few vars for symbol_file_command. 390 391 * target.h: Breakpoint takes a char * save area, not a char **. 392 393 * valprint.c (val_print): When unpacking bitfields, offset 394 the address in gdb of the value, if it is declared with a shorter 395 type. Remove the last "runtime kludge test" of host byte order. 396 397 * utils.c: Remove old my_bfd_read routine. 398 399 * stack.c (frame_info): Use target_has_stack. Print program counter 400 register's actual name rather than "pc", since it's called the 401 "ip" (instruction pointer) on the i960 (sigh). 402 403 * target.c (target_command): Add command for selecting a target 404 type and calling its open routine. This is used for initiating 405 communication with a particular target, in a generic way. 406 407 * tm-i960.h: Update for modern gdb. Remove semicolons from 408 various macros. Handle reading struct return convention, and 409 error-out attempts to return structs with the "return" command. 410 Be sure gdb doesn't think we know how to call functions in the 411 inferior. 412 413 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS 414 to i960_xxx in lower case. 415 (arg_address): Circumvent errors due to LOC_ARG_BLOCK 416 not being defined yet. 417 418 * remote.c (remote_open): Call start_remote to initialize 419 wait_for_inferior during open. 420 (remote_xfer_inferior_memory): Return length written rather 421 than errno value. 422 423 * remote-vx.c (target_command -> vx_open): Use new generic 424 target command. 425 * remote-eb.c, inftarg.c, exec.c: ditto. 426 427 * infrun.c: Fix comments. 428 (attach_program -> child_open): Use new generic target command. 429 (wait_for_inferior): Clear saved register values before target_wait, 430 so target_wait can set some of them if convenient. 431 432 * infptrace.c (fetch_inferior_registers, store_inferior_registers): 433 Return success indicator, not void. 434 (child_xfer_memory): Avoid fetching initial word if we'll 435 overwrite it anyway. 436 437 * infcmd.c (attach_command): Use new generic target open routine. 438 (_initialize_infcmd): Update doc on attach and detach commands. 439 (do_registers_info): Merge in a byte-order problem as a FIXME 440 comment. 441 442 * findvar.c (find_saved_register): Avoid problem in current frame. 443 (read_relative_register): Ditto. 444 (write_register): Convert byte order on the way out. 445 446 * exec.c (file_command): Add. 447 (add_to_section_table, exec_command): Use new bfd_map_over_sections. 448 (xfer_memory): Common function between core_xfer_memory and 449 exec_xfer_memory. 450 (exec_xfer_memory): Use it. 451 452 * pn-opcode.h: Document that a "PN" is a Gould PowerNode. 453 454 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c, 455 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c, 456 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall. 457 458Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com) 459 460 Merge Intel 960 port of gdb, continuing... 461 462 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read, 463 symbol_file_command): Pass from_tty arg to hush 'em up. 464 465 * coffread.c (symbol_file_command): Avoid output if from_tty != 1. 466 Add magic numbers for 960 COFF format. 467 468Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com) 469 470 Merge Intel 960 port of gdb, from Intel "1.2" release. 471 472 CHANGE_LOG entries from their port, which was based on 473 gdb+-2.8.0: 474 475 Thu Sep 6 11:02:22 PDT 1990 476 Remove temp file if download is interrupted. 477 478 Wed Aug 1 09:08:33 PDT 1990 479 Now uses binary protocol to talk to NINDY. 480 Old hex protocol (NINDY 2.13 and older) supported with -O switch. 481 Times out after 5 seconds when trying to talk to NINDY. 482 483 Tue May 29 12:54:49 PDT 1990 484 Added variable baud rate (-b switch). 485 Source code reorganization. 486 487 Thu Apr 26 11:09:55 PDT 1990 488 More cleanup of batch mode; specifically, execute "-s", "-e", and 489 "-se" switches as soon as they are encountered on the invocation line. 490 491 Fri Apr 20 13:47:15 PDT 1990 492 Add -brk switch. 493 494 Thu Apr 19 09:54:28 PDT 1990 495 Add 'reset' command. 496 497 Wed Apr 18 09:48:07 PDT 1990 498 After opening remote tty, wait for 1 second to go by without input 499 from it before trying to talk to NINDY (fixes problems with the 500 Heurikon HK80/V960E). 501 502 Mon Apr 4 16:33:05 PDT 1990 503 Some output was not being suppressed in 'batch' mode. 504 505 Thu Mar 22 15:31:11 PST 1990 506 Ask user if old symbol table should be deleted when new file is 507 downloaded. 508 509 Allow user to run a program downloaded before gdb960 was brought up. 510 511 Correct "exec-file" help message for i80960 context. 512 513 Correct bug in calculating user space address: could occasionally 514 corrupt user program. 515 516 Make sure to zero low-order bits in rip's because of bug in 960CA 517 A-step part: could cause operation faults when "next"ing across 518 a function call. 519 520 Correct bug that made it impossible to get source line numbers for 521 code loaded at addresses higher than 0x7fffffff. 522 523 Wed Jan 10 12:43:22 PST 1990 524 Open remote tty for exclusive use. 525 526 Fri Jan 5 12:14:42 PST 1990 527 Correct disassembly (CA manual was right after all): 528 opcode for sysctl is 0x659 529 530 Mon Oct 23 12:03:04 PDT 1989 531 Use G960BASE and G960BIN environment variables to find 'sx' utility. 532 533 Mon Oct 16 14:15:09 PDT 1989 534 "sfr0"-"sfr31" should have been named "sf0"-"sf31" 535 536 Mon Oct 2 15:56:31 PDT 1989 537 538 Added 960CA disassembly support. 539 540 To simplify maintenance: 541 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c 542 directly instead. 543 - eliminated opcode.h: incorporates tables into i960-pinsn.c 544 - moved 960-specific routines from i960-pinsn.c to i960-md.c 545 - made disassembly interface identical to that in gdmp960. 546 547 548 549Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint) 550 551 * target.h: Allow targets to stack. Add target_has_memory, 552 _registers, etc. Restructure memory access and "info files" 553 to walk the target stack. 554 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c, 555 target.c: Change tables to match target.h. 556 * inflow.c (child_mourn_inferior): pop child_ops. 557 (generic_mourn_inferior): Use new has_stack flag. 558 * infptrace.c (child_xfer_memory): New memory regime. 559 * inftarg.c (child_files_info): New "info files" regime. 560 * remote-eb.c: New memory regime, new info files. 561 * remote-vx.c: New memory regime, new info files. Now use 562 separate targets for VxWorks attachment to machine, and 563 actually running a process under VxWorks, since one has 564 stack & execution & regs and the other doesn't. 565 * remote.c: New memory regime, new info files. 566 * sparc-xdep.c (fetch_core-registers): New memory regime. 567 * target.c: New routines and support for stacked targets, 568 new memory regime, new info files regime. 569 570 571 Generalize section handling for an arbitrary number of sections, 572 including use of the new BFD (binary file) library. 573 * gdbcore.h: Add struct section_table. 574 * exec.c (build_section_table): Iterate all sections and 575 record what gdb needs to know about them. 576 (exec_command): Use it. 577 (exec_xfer_memory): Use the table. 578 (exec_files_info): Print the table. 579 * core.c (core_file_command, core_xfer_memory, core_files_info): 580 Likewise. 581 * source.c (find_source_lines): Use bfd_get_mtime. 582 * dbxread.c: Quick changes to make it compile with new BFD. 583 * utils.c (error): Avoid using bfd_error in generic routines. 584 585 * core.c (core_fetch_registers): Get from the ".regs" section of 586 the BFD core file. 587 * sparc-xdep.c (fetch_core_registers): Use the .regs info. 588 589 * inferior.h (attach_flag): Export. 590 * infcmd.c (run_command): use new target_create_inferior. 591 * infrun.c (child_create_inferior): Don't return result. 592 * Makefile.dist (VERSION): 3.91.4. 593 594Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint) 595 596 * breakpoint.c (bpstat_num): Handle breakpoints which have 597 since been deleted, such as temporary breakpoints. 598 infcmd.c (program_info): ditto. 599 600 * core.c (core_file_command): Display the frame where the core 601 dump occurred. 602 603 * main.c: lint. 604 605 * remote-vx.c (target_command): Merge in target command from 606 targ-vx.c. A few other cleanups. 607 608 * TODO, Projects: Lots more stuff to do... 609 610Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint) 611 612 Massive changes to wall off the remote-debugging interface 613 behind a function vector. The port to handle VxWorks targets 614 is also part of this. 615 616 All files: Replace references to renamed functions, 617 remove references to remote_debugging, remove references to 618 have_include_file, have_core_file in favor of target_has_stack, 619 target_has_memory, etc. 620 621 * Modularize the breakpoint interface. 622 breakpoint.h (BREAKPOINT_MAX): New define sets max length of 623 a breakpoint instruction. 624 breakpoint.c: struct breakpoint's shadow_contents now sized as 625 BREAKPOINT_MAX. 626 (insert_breakpoints): Vector to target to install breakpoints. 627 (remove_breakpoints): Vector to target here too. 628 Remove REMOTE_SA_SPARC kludges and other remote_debugging. 629 sparc-tdep.c (single_step): Use new breakpoint interface for 630 the single-step breakpoints. 631 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint): 632 New file, contains routines to insert and remove breakpoints by 633 reading out the old contents and later replacing them. This is 634 how ptrace breakpoints work, and many remote systems as well. 635 636 * tm-vxworks68.h: New config file, overrides a few things for 637 Wind River's preferences. 638 639 * target.h: New file, for transfer vector used to talk to the 640 inferior (child, attached, core, exec, remote, etc). All accesses 641 to the thing being debugged should come through these vectors. 642 target.c: New file, routines to handle transfer vector. 643 (various files): Add transfer vectors XXX_ops for the various 644 targets and pseudo-targets (core files, etc) we support. 645 646 * breakpoint.c (bpstat_stop_status): Further explorations of 647 watchpoints and why things don't work all the time. 648 (bpstat_alloc): New fn to allocate a bpstat and chain it. 649 650 * config.gdb: Only add "source ${srcdir}/.gdbinit" to 651 the local gdbinit if it doesn't already have it. 652 653 * core.c (core_ops): add and install. 654 Allow core debugging without exec file. 655 656 * dbxread.c (free_and_init_header_files): Merge two fns. 657 (end_symtab): Free named symbol table when a new version comes in. 658 (read_dbx_symtab): Relocate all kinds of symbols with base 659 address. First step toward handling different text, data, bss 660 reloc. 661 (add_file_addr_command): Renamed add_file_command. 662 (add_file_command): Vector to remote handler. 663 Add "load" as an alias for "add-file" command. 664 665 * defs.h: Allow "volatile" to be used in non-ANSI; use it for 666 non-returning functions. 667 668 * exec.c: Add exec_ops, and push it as a target when an exec 669 file is specified. 670 671 * infcmd.c (run_command): Pass executable file name and arg list 672 separately when starting an inferior. Permit "run" when no exec 673 file is specified, for VxWorks. 674 (detach_command): Move to child_detach in inftarg.c. 675 676 * inftarg.c: New file. Unix-child-specific routines, and the 677 child_ops structure. 678 679 * inferior.h (registers): Export "registers" as the way for 680 target dependent register handlers to find gdb's local copy of 681 the registers. Rename "stop_after_attach" to "stop_soon_quietly" 682 since it is now used by places that want wait_for_inferior to 683 handle the grunge but want to see every trap from the inferior. 684 685 * inflow.c (create_inferior): Pull out, and merge into infrun.c. 686 Eliminate remote_debugging hooks in terminal handling. 687 688 * infrun.c: Replace start_inferior with child_create_inferior. 689 Move all the hair of Unix shells and ptrace idiosyncracies into 690 child_create_inferior, so remote handlers don't have to deal. 691 Remove running_in_shell. Rename stop_after_attach to 692 stop_soon_quietly, and use it in a few other places where we want 693 to just call wait_for_inferior and get control back on the first 694 trap. trap_expected now never takes a value > 1. 695 (init_wait_for_inferior): Initialize static vars when a new 696 process is created. 697 698 main.c (gdbinit): Add new hook for .gdbinit file name, let 699 it be overridden by config files as GDBINIT_FILENAME. 700 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt. 701 Both of these are used for VxWorks gdb. 702 703 mcheck.c: rename include file "gmalloc.c" to avoid problems 704 with system include file "malloc.c". 705 706 param-no-tm.h: New include file, same as param.h but does not 707 include the default "tm.h" file. This is used in files where 708 the target is known, e.g. remote-eb.c or sparc-xdep.c. 709 710 param.h: Now just a shell that includes tm.h and param-no-tm.h. 711 712 remote-vx.c: New file, VxWorks remote debugging support. Uses 713 RPC routines that are shared with the target system, in directory 714 ${srcdir}/vx-share. 715 716 remote.c: Vectorize remote interface. 717 718 source.c: Globalize source_path, and make an alias "l" for "list" 719 since we now have the "load" command. 720 721 sparc-xdep.c: Use new param-no-tm.h. 722 723 symmisc.c (free_named_symtab): Add new function from Wind River. 724 However, ifdef it out for now while we think about what it should 725 really be doing. 726 727 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move 728 PREPARE_TO_STORE to 729 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since 730 non-Unix-children handle this with their own code in the target 731 transfer vector. 732 733 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to 734 source and target lists. Add vx-share to default list of include 735 directories. Add new files to src and target lists: mem-break, 736 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the 737 ${srcdir} versions of munch and createtags are used. 738 739 * valops.c (find_function_addr): Split out of call_function. 740 (call_function_by_hand): Rename call_function; this function 741 calls functions in the target by laboriously patching the target 742 word-by-word with the right stack, args, regs, etc. 743 744 745Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint) 746 747 Handle AMD 29000 a bit better. 748 749 * remote-eb.c (readchar): Mask received char log to make it readable. 750 (remote_start): Pass arguments down to executing program. 751 Make startaddr unsigned. 752 infrun.c (start_inferior): Accept args, pass them to 753 remote_start. 754 infcmd.c (run_command): Pass args down to start_inferior. 755 756 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying 757 the target object file format. 758 tm-29k.h: Pay heed to COFF_ENCAPSULATE. 759 760 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly. 761 am29k-tdep.c (examine_prologue): Better checking of function prefixes. 762 763Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint) 764 765 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze. 766 * TODO: We did a few things, we have more to do though. 767 768 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define. 769 * inflow.c (inferior_died): Clear deferred stores. 770 771 * Debug problems with dummy frames and calls to the inferior. 772 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c. 773 * sparc-tdep.c (do_restore_insn): Simplify. 774 (sparc_frame_find_saved_regs): Simplify and fix what we find. 775 (sparc_push_dummy_frame): Simplify and fix what we push. 776 (sparc_pop_frame): Slightly more hair here, deciding whether 777 we are restoring a saved PC or returning to a return address in %i7. 778 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read. 779 780 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__. 781 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc. 782 * obstack.h (chunkfun): ditto. 783 * defs.h (xmalloc, xrealloc): ditto 784 785 * utils.c (quit): Grab the terminal from the child if necessary. 786 787 * inflow.c (term_status_command): Rename to term_info, change 788 to "info terminal". 789 790 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions. 791 (is_delayed_branch): Speed up. 792 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables. 793 Still missing some float ops, and needs testing. 794 795 * Support for input and output radixes other than base 10 796 * defs.h (input_radix, output_radix): Declare. 797 * expread.y (yyparse, parse_number): Handle changes of input 798 radix, and ambiguous names-or-numbers in radixes >10. 799 * printcmd.c (print_scalar_formatted): Print formatted hex 800 numbers in varying column widths. 801 * valprint.c (val_print): Use output_format to print scalar ints. 802 (set_input_radix, set_output_radix, set_radix): Create. 803 (set_output_radix): Set output_format from output_radix. 804 (_initialize_valprint): add `set radix' but leave the others off. 805 806 * main.c (execute_command): Let stupid questions be turned off. 807 (_initialize_main): Handle "set stupidity", etc. 808 809 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h, 810 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint. 811 812Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint) 813 814 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release. 815 bfd stuff is still screwed up, but with some manual work, it 816 compiles. 817 818 * breakpoint.c (bpstat_do_actions): Start over if a command 819 proceeds the inferior, since the inferior will have stopped and 820 will need to have its new stop-actions taken care of. 821 822 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3 823 compiler fits, simplify it. 824 825 * gdb.texinfo (directory command): Doc new dir command. 826 source.c (directory_command): "dir" now puts things on the front 827 of the path, moves dups up front, and handles multiple names 828 on the command line, inserting each one in order. It also 829 blows away cached line and full_filename info. 830 831 * stack.c (backtrace_command): Skip "more stack frames follow" 832 unless interactive. 833 834 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in 835 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h, 836 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h. 837 The only odd one was Gould NP1, which had defined vprintf to 838 "printf"!!! 839 840 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch. 841 printcmd.c (print_command_1): Pass 'inspect' flag down as a global 842 variable, inspect_it. 843 valprint.c (print_string, val_print): Use the global inspect_it 844 to indicate whether to print in Epoch style or normal style. 845 846Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint) 847 848 * printcmd.c (call_command): add an alias for the "print" command 849 which runs expressions and doesn't print the result if void. 850 (print_command_1): implement it. 851 852 * command.c: Remove #if 0'd code. Initialize all the fields 853 in add_cmd (). Rename do_nothing_command to 854 not_just_help_class_command, and make it externally visible. 855 command.h: add user_commands to struct. 856 * main.c (define_command): Don't overload c->function with a char 857 string as well as a function pointer. 858 859 * eval.c (evaluate_subexp): Reinstall tiemann changes to 860 calling convention of value_struct_elt () that got dropped in 861 merge. 862 863 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c. 864 sparc-tdep.c (sparc_frame_find_saved_regs): ditto. 865 866 * tm-sparc.h (POP_FRAME): replace some constants with defines. 867 868 * sparc-xdep.c (store_inferior_registers): defer stores to regs 869 until a good time (e.g. when we are about to run the child), 870 saving ptrace calls. 871 * infrun.c (proceed): handle DO_DEFERRED_STORES. 872 * tm-sparc.h: define DO_DEFERRED_STORES. 873 874 * sparc-xdep.c (store_inferior_registers): when storing float 875 registers, don't store stack regs too. When storing the SP, 876 however, DO store the stack regs too. This fixes a bug in which 877 the dummy frame is not recognized when a call_function finishes, 878 because its frame pointer (in the stack regs) was never 879 initialized. 880 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid 881 even though we don't know how to read them from an inferior. 882 valops.c (call_function): Comment about storing SP. 883 884 * infrun.c (save_inferior_status): Save away the original bpstat 885 chain so it can be restored later. Install the copied version for 886 use by whoever saved the status. It will be blow away by 887 restore_inferior_status, and the original chain restored. This is 888 important for people who have pointers into the original. 889 890 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h, 891 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h, 892 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint 893 894 895Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com) 896 897 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h 898 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW. 899 Add stuff.c and kdb-start.c to the OTHERS list for tar files. 900 901Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint) 902 903 * Merge Mike Tiemann's multiple inheritance changes from Sun. 904 Store the baseclasses in a type struct starting from array element 905 0 rather than from the unusual array element 1. 906 907 dbxread.c: the above. 908 (virtual_context): Add 909 Read new debug information about which virtual function table 910 a virtual function is from, and store it in fn_field.fcontext. 911 912 symtab.h: Add fcontextt. Fix baseclass indices. Typo in 913 TYPE_FN_FIELD_STATIC_P. 914 915 symtab.c: the above. 916 valops.c: the above. Handle pointer casts of object *'s. 917 (search_struct_method): Add. 918 (value_struct_elt): First arg is now a pointer to a value, and is 919 modified on return. 920 921 valprint.c: the above. 922 values.c (value_virtual_fn_field): Add type arg. Handle 923 offsetting to the proper object when calling virtual fns. 924 The above. 925 (baseclass_addr): Add valuep arg. 926 927 * README: Document the current state of BFD config (missing). 928 * TODO, ChangeLog, Makefile.dist: Roll version. 929 * WHATS.NEW: Add summary of changes since 3.5. 930 931Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint) 932 933 * dbxread.c (read_struct_type): Clear bit vectors whenever 934 we allocate one. 935 symtab.c (B_CLRALL): define. 936 937 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by 938 using == rather than =. Huh... This fixes the dreaded problem 939 wherein builtin_type_int becomes TYPE_CODE_FLT. 940 941 * core.c (info_files): Show the inferior pid. 942 943 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB 944 already knows how to look in the source directory. 945 946 * Remove psymtab hair from many places. Remove duplicated code 947 for searching symbol tables. Hide psymtabs from most places. 948 Make it fast to get from a psymtab to its symtab. 949 950 blockframe.c (blockvector_for_pc): Remove psymtab hair. 951 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2. 952 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2. 953 dbxread.c: export psymtab_to_symtab, make it work if called N times. 954 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize 955 new symtab completely. New psymtabs get symtab pointer 956 initialized to zero. Remove MI warning printf. 957 symtab.h: Comments. Add psymtab to symtab pointer. 958 (PSYMTAB_TO_SYMTAB): New macro. 959 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it. 960 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and 961 compilation fields. 962 stack.c (backtrace_command): Avoid pre-pass to read symbols, if 963 verbose is not set. 964 (print_frame_info): Avoid special-casing symbols that have not yet 965 been read in. 966 967 * source.c (open_source_file): Quick path if we have already 968 located the source file by its full name. 969 970 * symtab.c (lookup_symbol): Use find_pc_symtab rather than 971 find_pc_psymtab. When a name is found in the misc function 972 vector, search the symbol table for its mangled name, not the 973 name that the user typed. 974 975 * bfd.h: Fix missing comment terminators, make #endifs match. 976 977 * valarith.c (value_less): Handle unsigned int comparisons. 978 Add FIXME about pointer compares, which assume host and target 979 pointers are the same. 980 981 * command.c (do_nothing_command): lint 982 dbxread.c: lint. Remove sort_syms. Document C++ visibility info, 983 fix comments on debug symbol format for visibility. Actually set 984 visibility of symbols. 985 main.c (echo_command): lint; use <readline/history.h>. 986 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint 987 obstack.h (_obstack_blank): Rearrange pointer math to avoid 988 pointing past end of allocated memory; saber complains. 989 obstack.h: Declare the external functions that we use. 990 valarith.h: use <string.h> 991 solib.c (solib_add): lint. 992 993Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint) 994 995 * main.c (initialize_main): Default info_verbose to off, now that 996 symbol reading is fast. 997 (quit_command): Avoid clobbering exec_bfd while quitting. 998 999 * Initial BFD (binary file diddling library) merger: 1000 coffread.c: Change AOUTHDR to struct exe_hdr. 1001 dbxread.c: ditto. 1002 core.c: initialize initialized data at compile time. 1003 (core_file_command): Move from coredep.c, convert to bfd. 1004 (xfer_core_file): Convert to bfd. 1005 exec.c (exec_file_command): use bfd routines. 1006 gdbcore.h: BFD. 1007 mips-tdep.c: Remove exec_file_command and friends. 1008 source.c: bfd. 1009 1010 * coredep.c: (fetch_core_registers) Convert core_file_command to 1011 fetch_core_registers. 1012 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto. 1013 1014 * utils.c: (error): Bogus crap, FIXME, to print bfd errors. 1015 (my_bfd_read): More bogosity, which I don't think we call. 1016 (program_name): Remove this atrocity asap! 1017 1018Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint) 1019 1020 * From Per Bothner: 1021 values.c: allocate_repeat_value was not clearing the 1022 optimized_out field. 1023 (value_static_field): minor stylistic fix (wrong macro was used). 1024 valops.c (value_struct_elt_for_address): didn't work for C++ 1025 static fields. 1026 1027 * signame.c (_initialize_signame): Initialize signal names once. 1028 1029 * breakpoint.h, command.c, copying.awk, defs.h, environ.c, 1030 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c, 1031 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint. 1032 1033 * remote-eb.c: Support user-settable baud rates on the serial port. 1034 1035 * tm-sun3.h (PREPARE_TO_STORE): fix typo. 1036 1037Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint) 1038 1039 * tconfig/sun3os4: Remove warning about native assembler, 1040 since it also occurs in the xconfig file. 1041 1042 * findvar.c (registers): Allocate some slop after `registers' 1043 to prevent stray accesses from trashing the next variable. 1044 1045 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes 1046 on the sun-3, by changing the #ifdef from `sun3' (which is not 1047 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX 1048 vars, which happened to follow `registers' in the executable. 1049 1050 * readline/history.c (history_search): Heed gcc-2's advice 1051 and parenthesize && inside ||). 1052 1053 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c, 1054 tm-29k.c: Insert FSF copyright headers. 1055 1056 * remote-eb.c: Better comments. 1057 1058 * Makefile.dist: Update to 3.91.6. 1059 * TODO: note PREPARE_TO_STORE problem. 1060 1061Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint) 1062 1063 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined. 1064 1065 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE). 1066 1067 * infrun.c (wait_for_inferior, at end): Don't set up 1068 prev_* if the inferior no longer exists. 1069 1070 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace 1071 CANNOT_EXECUTE_STACK. 1072 valops.c (call_function): Use it. 1073 1074 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY. 1075 1076 * inferior.h (PC_IN_CALL_DUMMY): New macro. 1077 infrun.c (wait_for_inferior, 2 places): Use it. 1078 1079 * values.c (value_being_returned): Only use 1080 EXTRACT_STRUCT_VALUE_ADDRESS if defined. 1081 1082 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the 1083 right thing for remote-eb.c. 1084 1085 * sun3-xdep.c: Remove extraneous call to remote_store_registers. 1086 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto. 1087 1088 * blockframe.c: Put get_frame_saved_regs inside #if !defined 1089 (FRAME_FIND_SAVED_REGS). 1090 1091 * findvar.c ({fetch,store}_registers): Check for 1092 REMOTE_{FETCH_STORE}_REGISTER macro. 1093 1094 * findvar.c (get_saved_register): Add argument lval and 1095 change meaning of argument addr. 1096 findvar.c: Change calls to get_saved_register to reflect 1097 new calling convention. 1098 valops.c (value_assign): Use get_saved_register instead of 1099 find_saved_register. 1100 1101Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com) 1102 1103 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not 1104 an (uninitialized) pointer to one. Use "&" when passing it 1105 to fread. 1106 1107Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com) 1108 1109 * coffread.c (getfilename): Use DGUX x_offset and x_name if 1110 defined. 1111 1112 * coffread.c (symbol_file_command): Put semicolon after 1113 "int from_tty". 1114 Put safe_to_init_tdesc_context in #if defined (TDESC). 1115 Put #ifdef TDESCs in 1st column for non-ANSI cpp's. 1116 coffread.c: #include <sys/stat.h>. 1117 (read_coff_symtab): Typo: in_source_files -> in_source_file. 1118 Add missing ')' in check for "lc%" and friends. Remove 1119 extraneous '}'. 1120 Declare read_one_sym() at top of file. 1121 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and 1122 MC68WRMAGIC can have the same value without causing a duplicate 1123 case. 1124 1125Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint) 1126 1127 * Allow a Makefile to be built without building the 1128 tm and xm file links that screw up builds in subdirectories. 1129 This is done with `config.gdb none', then you can do things 1130 like `make gdb.tar.Z'. 1131 * tconfig/none: Config file for no target system 1132 * xconfig/none: Config file for no host system 1133 * config.gdb: If no TM or XM files are called out by the 1134 host or target file, don't make links for them. 1135 1136 * cplus-dem.c: Add documentation. 1137 1138 * dbxread.c (read_ofile_symtab): Turn a fatal error into a 1139 simple error, so the user's gdb doesn't crash due to some object 1140 file problem (e.g. somebody is rebuilding the file out from under 1141 gdb). 1142 1143 * printcmd.c (print_address_symbolic): demangle the symbol. 1144 1145 * Makefile.dist (OTHERS): Remove tdesc-lib because it has 1146 Motorola copyrights in it. Make "make gdb.tar.Z" work. 1147 (alldeps.mak): sort and uniq all results from this; duplicates 1148 hose gdb.tar.Z link building. Remove RCS files from 1149 tconfig and xconfig. Add config files for sun386. Add 1150 a few odd files to OTHERS and HFILES. 1151 1152Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint) 1153 1154 * Makefile.dist: Pull solib.c to tconfig/sun?os4. 1155 Roll version number to 3.91.5. Make lint work in bindir. 1156 1157 * README: Document cross-debugging and new file structure. 1158 1159 * blockframe.c: Lint. Include "value.h" to declare read_register. 1160 (find_pc_partial_function): remove duplicate line. 1161 1162 * command.h: Lint. Declare error_no_arg and dont_repeat. 1163 1164 * tm-news.h: Remove inadvertently duplicated stuff. 1165 1166 * mipsread.c: Remove cache_pc_function stuff, now done cleanly. 1167 Clean up usage of misc_function_type. Declare some CORE_ADDRs. 1168 1169 * config.gdb: Allow `config.gdb host target' form. Clean 1170 up previous change that printed bogus messages when you just said 1171 `config.gdb'. 1172 1173 * core.c: #include "command.h" for lint. 1174 * dbxread.c: lint 1175 * eval.c: lint 1176 * main.c: Remove some casts of enums. Lint. 1177 * source.c: lint 1178 * symtab.c: lint 1179 * symtab.h: lint 1180 * expread.y: lint 1181 * valarith.c: lint 1182 1183 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd. 1184 1185 * sparc-tdep.c (isannulled): Take instruction as parameter, don't 1186 read it from memory. This will allow us to save ptrace calls 1187 eventually. Changed caller single_step too. 1188 1189 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs 1190 that we aren't going to use, saving many ptrace calls, especially 1191 when watchpointing or single stepping. Use some #define's for 1192 constants. 1193 (store_inferior_registers): Ditto. 1194 (core_file_command): Use some #define's for constants. 1195 1196 * tm-sparc.h: Add #define's for some register numbers, so we 1197 can eliminate the use of random constants in sparc-xdep.c. 1198 1199 * stack.c (frame_command, print_frame_info, up_command, 1200 down_command) Remove frame_changed, since it 1201 causes a bug and doesn't seem to do anything useful. In some 1202 places it was used as a flag, in others as a stack level (?). 1203 1204 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the 1205 default is to use the portable (vprintf) version rather than the 1206 kludge version. 1207 * xm-news.h (MISSING_VPRINTF): Add. 1208 1209 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint. 1210 1211Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint) 1212 1213 * Remove stuff that forces -Bstatic linking of gdb, and warnings 1214 about linking debugged programs -Bstatic in the sun?os4 config 1215 files in tconfig and xconfig subdirectories. 1216 1217 * main.c (main): Remove unreached exit(0) now that we exit 1218 via quit_command(). 1219 1220 * Create TODO file for online bug list. There are too many 1221 "little" bugs to keep track of on paper. 1222 1223 * Change Projects file to refer to bug-gdb@cygnus.com 1224 rather than kingdon@ai. 1225 1226Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint) 1227 1228 * Makefile.dist (VERSION): 3.91.4 now. 1229 1230 * symtab.c (init_misc_bunches): Rename from init_misc_functions. 1231 (condense_misc_bunches): Add sanity check that misc_count is 1232 the same as the number of symbols in the bunch. 1233 1234 * coffread.c: rename init_misc_bunches. Pass an argument 1235 to condense_misc_bunches (a zero). 1236 1237 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches 1238 every time we are called; don't rely on our caller to do it. 1239 (add_file): Remove call to init_misc_bunches. 1240 1241 * mipsread.c: Only warn, don't error, if unknown symbol types. 1242 This keeps an old gdb from falling on its face if it sees newly 1243 extended symbol info. Rename init_misc_bunches. 1244 1245Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint) 1246 1247 * Merge in changes from Per Bothner for DECstations and other 1248 MIPS stuff. The rest is Bothner speaking: 1249 1250 The next message is a merger of Alessando Forin's mips port with 1251 mine. I've tried to use my good if biased judgment to get 1252 the best of both. It *does* need testing. 1253 1254 Some of the changes are general, *not* mips-specific. 1255 1256 param.h: 1257 Didn't believe in little-endian bit order. 1258 There are still inconsistencies about whether flags 1259 like BITS_BIG_ENDIAN are integer (#if ...) or 1260 boolean (#ifdef ...). I tried to paper over them. 1261 1262 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h: 1263 Moved some misc_function code that was common to 1264 {dbx,coff,mips}read.c to symtab.c. 1265 In the process, I think I cleaned things up a bit. 1266 At the same time, moved obsavestring and obconcat to symtab.c. 1267 1268 dbxread.c: 1269 Removed obsolete condense_addl_misc_bunches (use 1270 condense_misc_bunches(1) instead). 1271 1272 exec.c: 1273 Needed to include <sys/dir>, at least on DECstations. 1274 1275 valops.c, mips-tdep.c, tm-mips.h: 1276 Added PUSH_ARGUMENTS macro to support funny argument-pushing 1277 conventions (when STACK_ALIGN is insufficient). 1278 Needed on mips, where doubles need 8-byte alignment, 1279 but ints only need 4. 1280 1281 mips-opcode.h: 1282 Removed cruft that was not being used. 1283 Merged in many fixes (most from Frank Yellin, fy@lucid.com). 1284 1285 mips-pinsn.c: 1286 Print $ before register-names (I think that makes things a little 1287 more consistent). 1288 Never print two instructions, even if one delays. 1289 Removed hex-disassemble set_cmd. (This is not mips-specific, 1290 so I think the argument is whether it is generally worthwhile or not. 1291 I'm inclined to think not, given how easy it is to 1292 convert between radixes in gdb.) 1293 1294 mipsread.c: 1295 This is basically Alessando's code. 1296 It doesn't use obstacks; I changed it to use obstacks 1297 in a few minor places where using malloc causes a 1298 memory leak. (Probably, more places could/should be changed.) 1299 I added record_misc_function where it was missing. 1300 In symbol_file_command and add_file_command, I tried 1301 to make the code consistent with more recent versions. 1302 Minor sylistic changes in parse_procedure. 1303 Make a .gdbinfo. psuedo-symbol point back to the real 1304 procedure symbol (using the isym field). 1305 1306 mips-tdep.c: 1307 This is basically from my port, but with a lot of details 1308 and a number of routines merged in from Alessando's version. 1309 I basically used my code "raw" backtrace (use heuristics 1310 from the actual code, rather than symbol table info) - though 1311 the idea is Alessandro's. I feel my code is a little cleaner 1312 here, particularly in being a little more flexible, such as being 1313 able to handle gcc-produced code (which it now can). 1314 It also doesn't do frame caching (which is not useful 1315 more recent gdb versions). 1316 I also used my code for push_/pop_dummy, more or less. 1317 I tried to incorporate AF's code for testing sigtramp 1318 while backtracing; I probably got it wrong. 1319 Added mips_print_register, which tries to scrunch as much 1320 information as possible on a screen... 1321 Removed the skip-prologue set_cmd. As with hex-disassemble (see 1322 under mips-pinsn.c), I don't see anything mips-specific here, 1323 and I don't see it being all that useful anyway. 1324 1325 tm-mips.h: 1326 Added a $fp psuedo-reg distinct from $fp (nice for gcc). 1327 Use more register names (rather than hard-cases numbers). 1328 1329Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint) 1330 1331 * Hack up 3.90.11 changes: 1332 1333 * Makefile.dist (depend): parameterize $(GCC). 1334 Add solib.c and solib.o. 1335 (readline): Fix vpath for both absolute or relative SRCDIR. 1336 1337 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs. 1338 Also, let the part I didn't understand at least compile so 1339 I can test the rest. FIXME. 1340 1341 * dbxread.c: Fix thinko using strcmp. 1342 (init_psymbol_list): declare static. 1343 (partial_symbol_file_open): Comment cleanups better, avoid 1344 cleaning up the string table since the caller will do that. 1345 Move the stat for mod time into symbol_file_command, temporarily. 1346 (There should be a mod time for each symbol file, eventually, 1347 to control its rereading. FIXME.) 1348 1349 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for 1350 SunOS, which gives error for shared libs otherwise. (From 1351 Schaefer, probably FIXME needs work for portability.) 1352 1353 * solib.c: Move #include "param.h" to work. 1354 Lowercase all the Uppercase Letters In the Messages. 1355 (find_solib): Clean up inferior_so_name for debug printouts. 1356 Allow no argument, to mean all shared libraries. 1357 1358 * symmisc.c: include param.h to get CLEAR_SOLIB. 1359 1360Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint) 1361 1362 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9 1363 to 3.90.11. ChangeLog entries below are from this. 1364 1365Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu) 1366 1367 * Version 3.90.11. 1368 1369 * Makefile.dist (HFILES): Add tm-sunos.h. 1370 1371Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu) 1372 1373 * Version 3.90.10. 1374 1375 * Makefile.dist (gdb.tar.Z): Change linking of config so it works. 1376 1377Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu) 1378 1379 * sparc-opcode.h Added single-operand version of rett. 1380 1381Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu) 1382 1383 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE): 1384 Put parens around gcc_p in expansion. 1385 1386Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu) 1387 1388 * utils.c (lines_to_list): Return 10 if lines_per_page == 0. 1389 1390Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu) 1391 1392 * Changes for Sun shared libraries: 1393 blockframe.c (find_pc_partial_function): If a non-text symbol 1394 is found, set *address = pc - FUNCTION_START_OFFSET. 1395 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]: 1396 Disable breakpoints instead of giving an error. 1397 source.c (select_source_symtab): Initialize cs_pst. 1398 symmisc.c: Call CLEAR_SOLIB if defined. 1399 symtab.h: Make text{low,high} CORE_ADDR not int. 1400 (psymtab): New field addr. 1401 solib.c: New file. 1402 dbxread.c: Move DECLARE_FILE_HEADERS outside functions. 1403 (record_misc_function): Give correct type for N_DATA symbols. 1404 (condense_misc_bunches): do "misc_function_count = j" regardless 1405 of inclink. 1406 Take code which is shared between symbol_file_command and 1407 add_file_command and put it into partial_symbol_file_{open,read}. 1408 Split add_file_command into add_file_command and add_file. 1409 Make psymtab_to_symtab read in the string table if the file 1410 is not symfile. 1411 Two new parameters to read_dbx_symtab and start_psymtab. 1412 tm-sunos.h: New file. 1413 1414Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu) 1415 1416 * infcmd.c: Change cont_command to continue_command and "cont" 1417 to "continue". 1418 1419Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu) 1420 1421 * breakpoint.c (enable_breakpoint): Get value of watchpoint. 1422 1423 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__. 1424 1425 * values.c (USE_STRUCT_CONVENTION): Check for structures of 1426 size 1,2,4,8 rather than size < 8. 1427 1428 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times 1429 as necessary, not just once. 1430 1431 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports. 1432 1433Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu) 1434 1435 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386 1436 1437 * tm-news.h: Add CALL_DUMMY_*. 1438 1439 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS. 1440 1441 * config.gdb: In list_host, list_target, use ${i}, not $i. 1442 1443Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu) 1444 1445 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc. 1446 1447 * sparc-opcode.h: Change all store floating-point state register 1448 instructions to have the right match & lose fields. 1449 1450Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu) 1451 1452 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass 1453 VPATH to readline. 1454 config.gdb: If srcdir != ., create readline directory and 1455 copy a makefile into it. 1456 1457 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for 1458 consistency with POSIX. 1459 1460 * breakpoint.c (bpstat_stop_status): Disable watchpoint 1461 when we exit its exp_valid_block. 1462 1463Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint) 1464 1465 * Makefile.dist: Bump version to 3.91.3. 1466 1467 * Clean up handling of breakpoint commands (somewhat). 1468 Prompted by Tiemann bug report "cont 10" doesn't work any more. 1469 1470 inferior.h: Add breakpoint_proceeded to inferior status struct 1471 and globals; save it and restore it. 1472 (clear_breakpoint_commands): Cleanup, remove old #define. 1473 1474 infrun.c (clear_proceed_status): Set breakpoint_proceeded. 1475 (save_inferior_status, restore_inferior_status): handle it also. 1476 (proceed): Remove earlier code that set breakpoint_proceeded. 1477 It is now set only in clear_proceed_status. 1478 (clear_proceed_status): Cleanup, use bpstat_clear rather 1479 than clear_breakpoint_commands. No callers need the stop_bpstat 1480 between clear_proceed_status and proceed. 1481 1482 infcmd.c: Add breakpoint_proceeded definition and comment. 1483 (cont_command, jump_command, signal_command): Move call to 1484 clear_proceed_status right next to call to proceed. 1485 1486 breakpoint.c (bpstat_do_actions): Avoid clobbering our 1487 caller's argument while running down the chain of breakpoints. 1488 Use new variable "breakpoint_proceeded" to determine when 1489 a command that it executes moves the inferior past the 1490 breakpoint. 1491 (bpstat_clear): Handle NULL argument. 1492 (bpstat_clear_actions): Avoid useless call to 1493 breakpoint_auto_delete. 1494 (delete_breakpoint): Clean up bpstat's that are pointing to 1495 the deleted breakpoint from the stop_bpstat chain. 1496 (breakpoint_auto_delete): Simplify. 1497 1498 * Clean up handling of EOF, error on stdin, etc. This was 1499 prompted by a network problem that caused gdb to go into an 1500 infinite loop filling up its malloc'd memory. 1501 1502 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions, 1503 not clear_breakpoints_commands, which is now gone. 1504 (main): If command_loop returns (e.g. from EOF on stdin), do 1505 a quit_command (looping back to command_loop if quit_command 1506 doesn't really quit). 1507 (command_loop): check result from command_line_input and 1508 exit if it returns NULL, rather than passing the NULL to 1509 execute_command. 1510 (gdb_readline): Free malloc'd result space before returning 1511 NULL for EOF. 1512 1513 * utils.c (query): Handle C-d to mean "yes", just as if the 1514 input was not a terminal. Also avoid infinite loop if EOF 1515 occurs in mid-input-line before newline. This allows 1516 query to be used at EOF on stdin with reasonable results. 1517 1518 * infrun.c (proceed): Set breakpoint_proceeded. 1519 1520 * values.c (value_as_long): Avoid infinite recursion for enums. 1521 (_initialize_values): Fix typo in help msg (kingdon). 1522 1523 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies, 1524 RL_LIB for linking. This allows -lreadline for linking 1525 and nothing for dependencies, once readline is a real library. 1526 1527 * config.gdb: Jim Kingdon: give useful error message if the 1528 host or target type is not recognized. 1529 1530 * defs.h (alloca): SPARC <alloca.h> does not declare alloca, 1531 it just defines it. Dumb, but deal with it. 1532 1533 * Jim Kingdon suggests: 1534 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS. 1535 1536Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint) 1537 1538 * Makefile.dist (VERSION): Bump version # to 3.91.2. 1539 1540 * Clean up Bothner's changes. 1541 1542 * blockframe.c (clear_pc_function_cache): New function. 1543 * blockframe.c: remake cache_pc_function_* static. 1544 * dbxread.c (symbol_file_command): remove references to 1545 cache_pc_function_* variables. 1546 * dbxread.c (read_struct_type): Use VOFFSET_STATIC. 1547 * printcmd.c: Avoid kludging a global variable (addressprint) 1548 to avoid printing the address of a string twice. Instead, 1549 pass the format letter 's' down low enough that it can be seen 1550 to avoid this problem. 1551 (print_formatted): Pass format arg to value_print. 1552 (restore_addressprint): Remove function. 1553 (do_examine): Avoid hacking addressprint, cleanups and such. 1554 (print_frame_args): Add a comment to a Bothner change. 1555 * symtab.h: define VOFFSET_STATIC and use it instead of "-1". 1556 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache 1557 to wipe out the values cached in blockframe.c. 1558 * symtab.c (find_method): Add comment saying how big you must 1559 allocate to be "big enough". Per being terse again. 1560 * valprint.c (val_print): Handle format letter "s" to print 1561 strings without addresses. Add comment to vtbl printing code 1562 which casts with wild abandon. Rearrange reference-printing 1563 code so it prints: 1564 @0xaddr: value (print w/addressprint) 1565 value (print w/~addressprint) 1566 @0xaddr (parameter lists w/addressprint) 1567 or nothing (parameter lists w/o addressprint) 1568 1569Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint) 1570 1571 * Merge more changes from Per Bothner: 1572 1573Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise 1574annoying) that I tried to improve it. Here are my suggestions. 1575 1576 These patches all attempt to handle TYPE_CODE_REF (as in C++) better. 1577 1578 findvar.c: 1579 Do automatic de-reference when taking the address of a reference. 1580 printcmd.c: 1581 Don't deref_ref when printing parameter lists. 1582 valops.c: 1583 More attempts at treating refernences properly. 1584 valprint.c: 1585 In val_print, if deref_ref==0, don't print dangling " = ". 1586 value.h: 1587 Add COERCE_REF macro, which de-references an REF. 1588 1589 * Merge changes from Per Bothner: 1590 1591* Fixed (Sony news)-specific configuration problems. 1592* Fixed other problems with using vanilla pcc and libc (enum problems; 1593assumption that vsprintf exists). 1594* Some major speed-ups (finc_pc_partial_function now caches a match; 1595parsing avoids duplicate symbol_lookup calls). 1596* Changed handling of baseclasses (no longer use baseclasses field 1597of struct type, use the first n_baseclasses fields instead). 1598* Various minor changes/fixes, most C++-related. 1599 1600blockframe.c: 1601Cache the most previous match from find_pc_partial_function. 1602(Save both low and high ends of matching function's pc range.) 1603This speeds up the loop of infrun.c:wait_for_inferior quite 1604a bit, and makes step/next commands much zippier. 1605command.c: 1606Added an enum->int cast (otherwise, some compilers barf). 1607dbxread.c: 1608No longer set baseclass offset to 0, since multiple 1609inheritance now mostly works. 1610Added a number of casts, to shut up compiler warnings 1611(after stabs where made enums, not ints). 1612When discarding a symbol table (in symbol_file_command), 1613must clear the cache introduced in blockframe.c. 1614Don't convert $vtbl_ptr_type to vtbl any more. 1615Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h). 1616Mask off sign bit emitted by g++ for virtual table offset. 1617Set voffset to -1 (not 1) for static member functions. 1618expread.y: 1619Changed parsing/lexing of names to avoid doing symbol lookup twice 1620(once when lexing to determine symbol class, once for real). 1621Now only call symbol_lookup once. Fields of 'this' win especially big. 1622printcmd.c: 1623Subpress printing addr twice in the case of 'x/s addr'. 1624symtab.c: 1625lookup_basetype_type is no longer used. 1626Add find_methods as recursive helper function to decode_line_1. 1627This allows multiple inheritance to work. 1628Also, once one or more matches has been found, do not look in 1629base-classes. (Baseclass methods would be overridden, anyway.) 1630symtab.h: 1631Removed baseclasses array in struct type. 1632Instead of using baseclasses[i], use fields[i-1]. 1633Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual. 1634Changed sign convention of voffset (previous was inconsistent). 1635tm-news.h: 1636Some macros (CALL_DUMMY and relatives) were missing. Put them back. 1637utils.c: 1638Used to assume existence of vsprintf. Re-written to not need it 1639if HAVE_VPRINTF is undefined. 1640valops.c: 1641typecmp was too pessimistic. Made it less so. 1642valprint.c: 1643Don't print space after address. 1644If vtable points to a misc symbol (with 0 offset), print it, 1645since that indicates the actual class of the object. 1646Changed ype_print_derivation_info to use new inheritance 1647scheme (without baseclasses vector). 1648values.c: 1649In value_primitive_field, fixed some bugs left over from previous set of fixes. 1650Also, changes needed because TYPE_BASECLASSES were removed. 1651xm-news.h: 1652REGISTER_U_ADDR didn't work for PC. Rewrote to use an array. 1653 1654Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint) 1655 1656 * source.c: 1657 If there is no path set, and the symbols don't indicate what directory 1658 a file was compiled in, look in the current directory. But either 1659 a path or a known compilation directory will prevent this. 1660 1661 * dbxread.c: 1662 Three independent bug fixes: 1663 * Remove the #if 0 block that breaks some stuff. 1664 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C; 1665 adapt gdb to either SunOS 4.0.* or 4.1. 1666 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think. 1667 1668 * symtab.c: 1669 Instantiate the class T when looking for methods in it. (Tiemann@sun) 1670 1671 * valprint.c: 1672 (type_print) Demangle the name being printed. 1673 (type_print_base) Handle botched demangling without coredump (tiemann). 1674 1675 * values.c: 1676 (check_stub_method): Document routine. 1677 (tiemann) fix bug for no-arg functions 1678 Avoid clobbering beyond end of malloc'd storage. 1679 Terminate the argument list properly. 1680 1681Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu) 1682 1683 * Changes merged by John Gilmore: 1684 1685breakpoint.c: 1686 In breakpoint_1, use new print_address_symbolic instead 1687 of find_pc_partial_function. (This forces use of assembler-level 1688 addresses, and avoids misleading non-mangled source-level names.) 1689cplus-dem.c: 1690 Generalize ansi argument such that -1 means skip arglist totally. 1691 Removed global variable print_ansi_qualifiers (which made 1692 code non-reentrant), in favor of extra explicit arguments 1693 to internal routines. 1694printcmd.c: 1695 Add new helper function print_address_symbolic. 1696 Use find_pc_misc_function instead of find_pc_partial_function 1697 (since we want assembler-level symbols here). 1698stack.c: 1699 Print unknown function as just "f (...)", not "f (...) (...)". 1700 Use new fputs_demangled explicitly. 1701symtab.c: 1702 Fixed a typing violation (problem: value.h cannot be imported 1703 without renaming many variable in this file). 1704 lookup_symbol: If no matching misc_func, look for a C++-mangled name. 1705 decode_line_1: Moved forward some never-reached code. 1706 Made decode_line_2 skip function prologues correctly. 1707utils.c: 1708 fputs_filtered should not demangle by default. 1709 Add new fputs_demangled to demangle on demand.. 1710valops.c: 1711 Change value_struct_elt to use value_primitive_field (using recursive 1712 utility function search_struct_field). This allows foo.bar to work 1713 for multiple inheritance (so far only for data fields). 1714 Change check_field in the same way (recursive helper function 1715 to support multiple inheritance). 1716 (Note: there are more of these problems that I haven't fixed. 1717 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.) 1718 value_of_this: 'this' symbol name is now just "this", note "$this". 1719valprint.c: 1720 Don't print static members. 1721 Avoid printing "members of <type>" if there are none. 1722 Simplified type_print_derivation_info by merging duplicate code. 1723 Remove useless blank lines in type_print_base (ptype command). 1724value.h: 1725 Added declaration of new routine value_primitive_field. 1726values.c: 1727 Added value_primitive_field which is generalized version of 1728 value_field that can handle multiple inheritance (non-zero offsets etc). 1729 Re-implemented value_field to call value_primitive_field. 1730 1731Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint) 1732 1733 * infcmd.c -- insert else to avoid 'delete env' coredump when you 1734 delete the whole environment. Karl Berry reported the bug. 1735 * source.c - fix openp to avoid //'s in filenames, which 1736 trigger an Emacs bug causing it to not be able to find files 1737 when running gdb in a window. 1738 * dbxread.c - zap the #if 0 that botches the add-file code. 1739 It seems to work a lot better without all the code commented out. 1740 1741Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com) 1742 1743 * Merge Tiemann's and Ted Goldstein's changes, detailed below, 1744 into gdb-3.90.9. 1745 1746Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem) 1747 1748 * Makefile - added a ${CFLAGS} to a couple of entries, 1749 added remote-sa.sparc.c 1750 * added remote.sa-sparc.c, a modification of remote.c 1751 which conducts a dialog directly with the SparcStation prom. 1752 * breakpoint.c, infrun.c, sparcdep.c added 1753 remote_insert_breakpoint(), and remote_remove_breakpoint() 1754 to breakpoint.c instead of directly writing breakpoint instructions. 1755 * sparcdep.c on remote_debugging,there is no need 1756 to remove signle step breakpoint instructions. 1757 * main.c added "-epoch" flag and "int epoch_interface" to main.c 1758 global variable 1759 * printcmd.c - epoch interface sends lisp expressions to open up 1760 epoch windows on inspection. 1761 * valprint.c - added arrayprint, and addressprint and made adding 1762 format controls easier 1763 * wait.h added a couple of undef's because we were getting 1764 complaints about WSTOPSIG and WTERMSIG begin redefined. 1765 1766 1767Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham) 1768 1769 * symtab.c (decode_line_1): Add support for handling method stubs 1770 in the type information. 1771 1772Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham) 1773 1774 * values.c (baseclass_addr): Run loop from INDEX+1 to 1775 N_BASECLASSES; otherwise, we can still get into a loop. 1776 @@ This should be restructured to use a cleaner search strategy. 1777 1778Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham) 1779 1780 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new 1781 abbreviation "Tt" for tags which have the same name as their 1782 typedecls. 1783 1784Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham) 1785 1786 * symtab.c (list_symbols): add ability to set breakpoints on all 1787 the functions which match a particular regular expression. 1788 1789Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham) 1790 1791 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we 1792 should print ANSI qualifiers (such as `const' and `volatile'). 1793 All callers changed to call with ANSI == 1, except from 1794 `check_method_stub', which uses old-style syntax. 1795 1796 * symseg.h (struct fn_field): Remove unneccessary `args' field. 1797 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined. 1798 1799 * values.c (check_stub_method): New function. 1800 1801 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x'). 1802 1803 * dbxread.c (read_type): Handle new GNU C++ method type stubs. 1804 * valprint (type_print_base): Ditto. 1805 1806 * symtab.c (gdb_mangle_typename): New function. 1807 1808Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla) 1809 1810 * breakpoint.c (catch_command): New function. Provides a 1811 mechanism to set breakpoints based on catch clauses. 1812 (disable_catch): Similar, but disables breakpoints on catch 1813 clauses. 1814 (delete_catch): Similar, but deleted breakpoints on catch clauses. 1815 1816Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla) 1817 1818 * blockframe.c (blockvector_for_pc): New function. 1819 * blockframe.c (block_for_pc): Changed to call 1820 `blockvector_for_pc' and get the block itself. 1821 1822 * stack.c (catch_info): New function. Prints info about 1823 exceptions which can be caught in the current frame. 1824 * stack.c (print_frame_label_vars): New function. Similar to 1825 `print_frame_local_vars'. 1826 * stack.c (print_block_frame_labels): Prints out labels that are 1827 defined in this frame.
