Some emulations 578 pass object identifiers (capabilities?) to/from the simulated code 579 (for instance the phandle in OpenBoot). The cap object is able to 580 check/map between internal and external (target program) 581 representations of each identifier. 582 583 * os_emul.c, emul_chirp.h, emul_chirp.c, Makefile.in: Add 584 preliminary hooks for a kernel mode IEEE-1275 emulation. 585 586 * cpu.h, cpu.c (cpu_create, cpu_os_emulation, cpu): Add os_emul to 587 list of arguments passed in when creating a cpu.

Also, only 764 support 2 function units an insn can use, rather than a loop. 765 766Fri Nov 17 14:08:08 1995 Michael Meissner <meissner@tiktok.cygnus.com> 767 768 * table.c (table_entry_read): Move setting entry->line_nr to after 769 the model specific fields so the line numbers for the annex are 770 correct. 771 772 * cpu.c (cpu_{create,init,halt}): Check for WITH_MODEL_ISSUE 773 before calling the model functions. 774 775 * debug.c (trace_descriptor): Add trace_model support. 776 * debug.h (trace_options): Ditto. 777 778 * igen.c (gen_icache_h): Create type idecode_cache as void if not 779 caching instructions. 780 (gen_model_{c,h}): Drop model_issue support. Add support for 781 model_cleanup. 782 (lf_print_my_prefix): Initialize a const itable_index with the 783 current index. 784 (lf_print_c_semantic): Call model_cleanup at the end of the 785 function to check for instructions that aren't supported yet by 786 the scheduling code. 787 788 * mon.h (count_type): New type for counters. 789 * mon.c: Use count_type instead of unsigned. 790 791 * ppc-instructions: Redo scheduling code once again. Make it all 792 inline friendly. Instead of having general code emitted by igen, 793 go the route of having each semantic routine call the appropriate 794 module. 795 796Thu Nov 16 09:52:26 1995 Michael Meissner <meissner@tiktok.cygnus.com> 797 798 * table.c (table_entry_read): Allow the annex to have blank lines. 799 800 * ppc-instructions: Change lines in model stuff that just have a 801 tab to just newline. Add 601 support. Document most instructions 802 in terms of model specific timing information. Drop 'FUNCTION' 803 from PPC_FUNCTION_UNIT_xxx enums. Change PPC_UNIT_UNKNOWN -> 804 PPC_UNIT_BAD. Add TRACE(trace_tbd) for all data cache 805 instruction.s. Signal illegal instruciton if data cache block 806 invalidate is issued from problem state. 807 808 * igen.c (max_model_fields_len): New static to keep track of the 809 max size for the model specific fields. 810 (model_c_insn): Use max_model_fields_len to size fields. 811 (insn_table_insert_insn): Set max_model_fields_len. 812 (model_table_insert): Ditto. 813 (gen_model_{c,h}): Model_issue is now called with a processor 814 argument. 815 816 * debug.c (trace_description): Add support for trace_tbd. 817 818 * mon.c (mon_issue): Pass processor argument to model_issue. 819 820 * Makefile.in: Delete all function unit support, since the newer 821 table driven model support replaces it. 822 * cpu.{c,h}: Ditto. 823 * mon.c: Ditto. 824 * inline.{c,h}: Ditto. 825 * std-config.h: Ditto. 826 * options.c: Ditto. 827 * configure{,.in}: Ditto. 828 * Makefile.in: Ditto. 829 * psim.c: Ditto. 830 * function_unit.{c,h}: Delete these now usused files. 831 832 * std-config.h (WITH_MODEL_ISSUE): Add new macro on whether to 833 trace instructions in a model specific manor. 834 * options.c (print_options): Print it out. 835 * configure{,.in}: Add --enable-sim-model-issue option. 836 * Makefile.in: Add --enable-sim-model-issue flags. 837 * igen.c (lf_print_c_semantic): Add call to mon_issue here. Check 838 for WITH_MODEL_ISSUE. 839 * mon.c (mon_issue): Remove call to mon_issue_here. 840 841 * ppc-instructions: Move branch tracing to the actual branch 842 instructions, rather than testing it in model_issue. Add code to 843 code successful/unsuccessful branch predictions, and the number of 844 conditional branches that fell through. 845 846Wed Nov 15 17:32:13 1995 Michael Meissner <meissner@tiktok.cygnus.com> 847 848 * cpu.h (cpu_model): Add declaration. 849 850 * cpu.c (struct _cpu): Add model_ptr to hold model specific 851 information. 852 (cpu_model): Return the model internal pointer. 853 (cpu_{create,init,halt}): Call the appropriate model function. 854 855 * inline.c (mon.c): Move include of mon.c after model.c. 856 857 * mon.c (_cpu_mon): Add fields to count unaligned memory 858 references. 859 (mon_issue): Call model_issue, not function_unit_issue. 860 (mon_{read,write}): Count # of unaligned memory accesses. 861 (mon_print_info): Switch to calling model_mon_info and 862 model_mon_info_free instead of function_unit version.

Use annex field for model-macros 892 now. 893 894 * configure.in (--enable-sim-inline): If --enable-sim-inline=no, 895 also define INLINE as nothing. 896 * configure: Regenerate. 897 898 * std-config.h (INLINE): Rather than nuking INLINE, only define it 899 as __inline__ if any of the INLINE flags are non-zero. 900 901 * options.c (print_options): Print out WITH_XOR_ENDAIN. 902 903Mon Nov 13 23:03:45 1995 Andrew Cagney <cagneyhighland.com.au> 904 905 * ppc-instructions (rfi): Add missing code. 906 907 * cpu.c (cpu_get_time_base): Fix calculation of current value of 908 time base register. 909 910 * ppc-spr-table (TBL, TBU): Fix TBL/TBU entries - was confusing 911 m[tf]tb with m[tf]spr. 912 913 * ppc-instructions (mtspr, mfspr): Fix mttbl - wasn't storing 914 lower word. 915 916Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au> 917 918 * std-config.h (INLINE, STATIC_INLINE): Was being set to static 919 inline.. Only problem being that with ppc-opcode-simple this gave 920 it the chance to inline all the idecode functions with potentially 921 disasterous results on a 16mb PC. For moment hobble INLINE. 922 923 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by 924 default ... 925 926 * configure.in: Tweek flags passed to gcc for --with-sim-warnings. 927 Firstly make them errors and secondly remove the options gcc-245 928 doesn't reconize. 929 930Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au> 931 932 * misc.c (zalloc), cpu.c (cpu_init), devices 933 (console_io_read_buffer_callback, icu_io_read_buffer_callback, 934 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset), 935 sim_calls.c (zalloc) : replace bzero() with memset(). 936 937 * emul_netbsd.c (write_direntries), psim.c (psim_read_register, 938 psim_write_register): replace bcopy() with memcpy(). 939 940Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au> 941 942 * configure.in: for --disable-sim-inline (--enable-sim-inline=no), 943 force DEFAULT_INLINE to 0 rather then trusting the std 944 configuration. 945 946Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au> 947 948 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix 949 generation of switch entries in tables - treat the same as 950 cracking/semantic functions. 951 952 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation 953 of a boolean switch statement (field zero or non-zero). 954 955 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the 956 switch/table generation ability of igen. 957 958 * igen.c (idecode_switch_leaf): Fix code output when a switch 959 statement needs to look up a table. 960 961 * igen.c (idecode_declare_if_switch): New function called from 962 gen_idecode_c - need to declare any idecode switch functions 963 before they are used in idecode tables. 964 965 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf, 966 idecode_crack_insn): Add is_inline_function argument to code 967 printing cracker functions which indicates if STATIC_IDECODE or 968 STATIC_INLINE_IDECODE should be used for definition. For 969 idecode_crack_insn (which implies not duplicating/expanding) don't 970 declare function as inline - we assume that the only time this is 971 code is generated is when things are being tested. For 972 idecode_crack_leaf, make static (instead of INLINE) if the 973 instructions parent is a table as function will always be called 974 via a table. 975 976 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not 977 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be 978 called directly, all others are called via a table. 979 980 * igen.c (lf_print_semantic_function_header, semantics_h_leaf, 981 semantics_h_insn, semantics_h_function, 982 lf_print_c_semantic_function, semantics_c_function): Add 983 is_inline_function argument to lf_print_semantic_function_header 984 to indicate if an inline or static function declaration/definition 985 should be output. Depending on situtation call accordingly: 986 functions (not instruction semantic routines) are always inline; 987 Semantic routines are made inline when there is no icache (cache 988 will contain the function address) and are duplicating (see above) 989 and the parent of the instruction is a switch statement. 990 991 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC 992 and moved to insn_table_find_opcode_field. 993 994 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields). 995 996 * igen.c (model_c_insn): Suggestion - document the name of the 997 instruction on each line of the instruction model table. 998 999Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au> 1000 1001 * emul_netbsd.c (do_ioctl): Cleanup compilation. 1002 1003 * sim_callbacks.h (__attribute__): Only define if not defined (was 1004 already defined on NetBSD host). 1005 1006Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au> 1007 1008 * std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New 1009 macro, indicates if the PowerPC's horrible XOR endian mode should 1010 be suported. Add to configure and make. 1011 1012 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c 1013 (vm_instruction_map_read): If XOR endian, xor the address 1014 with a value from an xor table (indexed by size of access). 1015 1016 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context): 1017 set up xor table to xor if there is a conflict between the 1018 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move 1019 check of suported change of endian mode from cpu.c to vm.c. 1020 1021 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer): 1022 Hopefully added correct hack to handle XOR endian mode. 1023 1024 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates 1025 little endian mode, the model accepts miss aligned transfers. 1026 1027 FIXME: Need to create an `init' device that, during 1028 initializatioin for XOR mode, it mushes (XOR address) all the dma 1029 data before passing it on to the core for storage. Just like the 1030 real thing really. 1031 1032Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au> 1033 1034 * devices.c (halt_io_write_buffer_callback): Use value written to 1035 halt device to determine exit status.

Appears to 1545 give about a 10% gain in performance if everything enabled. Also 1546 takes about 150mb of swap to build. 1547 1548Wed Nov 1 10:49:48 1995 Michael Meissner <meissner@tiktok.cygnus.com> 1549 1550 * emul_netbsd.c (do_exit): Print arguments and close parenthesis 1551 if tracing, since exit doesn't go through emul_exit_call. 1552 (do_read): Print arguments if tracing. 1553 (do_write): Ditto. 1554 (do_open): Ditto. 1555 (do_break): Ditto. 1556 (do_kill): Ditto. 1557 (do_dup): Ditto. 1558 (do_sigprocmask): Replace trace with printing arguments if 1559 tracing. 1560 (do_ioctl): Print arguments if tracing. 1561 (do_umask): Ditto. 1562 (do_dup2): Ditto. 1563 (do_fcntl): Ditto. 1564 (do_gettimeofday): Ditto. 1565 (do_getrusage): Ditto. 1566 (do_fstatfs): Ditto. 1567 1568 * filter_filename.c: New file to provide filter_filename to strip 1569 the directory prefix from a file. 1570 * filter_filename.h: New include file to declare filter_filename. 1571 1572 * debug.h: Include filter_filename.h. 1573 (TRACE,DTRACE,ERROR): Use filter_filename on __FILE__. 1574 1575 * misc.h: Include filter_filename.h. 1576 (ASSERT): Use filter_filename on __FILE__. 1577 1578 * igen.c (lf_print_my_prefix): Use filter_filename on the filename 1579 argument. 1580 1581 * Makefile.in: Add filter_filename support. 1582 1583 * ppc-instructions (dcbi, icbi): Make these NOPs rather than 1584 invalid instructions. 1585 1586 * configure.in: Add support for more --enable-sim-* switches. 1587 Use config.make and config.hdr to write to Makefile and config.h 1588 respectively. Don't rewrite Makefile, just append to it. 1589 * configure: Regenerate. 1590 * config.{make,hdr}: New shell scripts. 1591 1592 * Makefile.in: Remove all variables set by configure.in. 1593 (psim.o): Depend on $(BUILT_SRC) also. 1594 1595 * emul_netbsd.c (do_gettimeofday,do_getrusage): When comparing an 1596 integer, use 0, not NULL. 1597 1598Tue Oct 31 15:20:04 1995 Michael Meissner <meissner@tiktok.cygnus.com> 1599 1600 * configure.in: Add support for --enable-sim-inline, 1601 --enable-sim-bswap, --enable-sim-cflags, --enable-sim-complex, 1602 --enable-sim-switch, --enable-sim-duplicate, --enable-sim-filter, 1603 and --enable-sim-endian switch to control various Makefile 1604 variables. 1605 * configure: Regenerate from configure.in. 1606 * Makefile.in: Add various Make variables that the various 1607 switches alter. 1608 1609 * std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC 1610 and optimizing by default. 1611 1612Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au> 1613 1614 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now 1615 make them functions again. Appears 2.6.3 is confused by just a 1616 macro. 1617 1618Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au> 1619 1620 * ppc-endian.c (SWAP_8): Fix 8 byte swap! 1621 1622 * psim.c (psim_create): Not correctly checking that runtime 1623 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT 1624 matched the compiled in ones. 1625 1626 * debug.h (ITRACE), igen.c: Tidy up more tracing flags - 1627 trace_semantics is now different to trace_idecode, the former 1628 checks the cache. 1629 1630Tue Oct 24 21:54:13 1995 Andrew Cagney <cagney@highland.com.au> 1631 1632 * ppc-instructions (mtsrin): Missing instruction 1633 * ppc-instructions (mfsrin): Missing instruction 1634 * ppc-instructions (eieio): Missing instruction 1635 1636Tue Oct 24 20:55:29 1995 Andrew Cagney <cagney@highland.com.au> 1637 1638 * build-psim: New shell script - see internals for usage, 1639 simplifies the process of building custom simulators. 1640 1641Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney@highland.com.au> 1642 1643 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the 1644 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2. 1645 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE 1646 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on 1647 the instruction or data critical paths. 1648 1649 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from 1650 the inclusion of device_tree.c/emul_generic.c. 1651 1652Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au> 1653 1654 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace 1655 system.[hc]. Start of suport for multiple emulations and 1656 emulation state (os_emul object). 1657 1658 * emul_generic.[hc]: Start of code to implement proper system call 1659 tracing (from spy). 1660 1661Sun Oct 22 21:33:51 1995 Andrew Cagney <cagney@highland.com.au> 1662 1663 * cpu.h, cpu.c (cpu_init): New function, zero the registers before 1664 the processor is started. Fixes problem of registers being 1665 undefined when restarting from within gdb. 1666 1667 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the 1668 instruction cache (if present). Fixes problem of cpu caching gdb 1669 breakpoint instructions. 1670 1671 FIXME: PSIM sometimes aborts calling error(), it should instead 1672 call sim_error() say which takes care of housekeeping such as 1673 saving the CIA before calling error. 1674 1675 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is 1676 used when restarting a simulation because the latter has the 1677 unwanted side effect (well I as a kernel hacker think it is) of 1678 performing an isync when the instruction stream doesn't contain 1679 one. 1680 1681Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au> 1682 1683 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance 1684 monitoring module. Counts both instructions issued and 1685 load/stores. 1686 1687 * NOTE: mon does not contain to count instruction loads as this 1688 information is already available from the mon_issue() hook. 1689 1690 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code. 1691 1692 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach 1693 a common monitor to each of the cpus. Delete 1694 cpu_increment_number_of_insns() and cpu_get_number_of_insns() 1695 replaced by copied code in mon.[hc]. 1696 1697Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au> 1698 1699 * sim_calls.c, main.c, psim.c (psim_create): always create 1700 `WITH_SMP' cpus. The actual number of CPU's active in a 1701 simulation run is taken from the device node: /init/smp (an 1702 integer). WITH_SMP changed to 2 (remember to put it back to 0). 1703 1704Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au> 1705 1706 * system.c: More system call emulation. If code appears NetBSD 1707 specific, make conditional to being compiled on a NetBSD system 1708 (sigh). 1709 1710Wed Oct 18 23:02:20 1995 Andrew Cagney <cagney@highland.com.au> 1711 1712 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new), 1713 lf.[ch](new), table.[ch](new): Split into two generators - igen 1714 that outputs the instruction tables and dgen that outputs the spr 1715 tables. Add -f (filter out) flag to igen to filter out certain 1716 instructions (ex 64 bit ones) from the created tables. Include 1717 $(LIBIBERTY_LIB) in link options in case host lacks some libc 1718 functions. 1719 1720 * NOTE: igen, since it was originally written for the 1721 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}. 1722 1723 * Makefile.in, std-config.h, ppc-cache-rules(new), 1724 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create 1725 cache-rule and opcode-rule tables from macros found std-config.h. 1726 Delete corresponding macro's from std-config.h. 1727 1728 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output 1729 an table of all the instructions. Code to output a type 1730 enumerating all the instructin names. 1731 1732 * igen.c(lf_print_c_semantic): Move call to increment instruction 1733 counter so that it occures _after_ the instruction has been fully 1734 validated, was double counting illegal/invalid instructions. Add 1735 conditional so only compiled in when WITH_PROFILE enabled (enabled 1736 by default). 1737 1738 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include 1739 itable.h, count individual instruction types not just total, 1740 adjust reporting functions to output this. 1741 1742 * ppc-instructions (64 bit Load Doubleword with Update Indexed): 1743 Had 32./ instead of 31./ 1744 1745 * ppc-instructions (64 bit Store Double Word Conditional Indexed): 1746 bitrot - updated to use newer CR register operators. 1747 1748 * ppc-instructions (64bit Floating Convert from Integer 1749 Doubleword): Correct call to Round_Float(). 1750 1751Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au> 1752 1753 * basics.h: #include "sim_callbacks.h" earlier so that its 1754 prototypes are declared in all other header files. 1755 1756 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update 1757 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into 1758 bits.h. 1759 1760 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*): 1761 Add size of buffer argument to functions writing a string into a 1762 buffer. Check for buffer overflow. 1763 1764Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au> 1765 1766 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing 1767 of each device. Make parameter names consistent so macros work. 1768 Use macro's in device functions. 1769 1770 * device_tree.c, devices.h, devices.c: include path to device in a 1771 devices node when creating it. 1772 1773 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'. 1774 1775 * core.c: add tracing of core-device, adjust parameter names in 1776 core functions to be consistent with those in devices*. 1777 1778Sun Oct 15 20:33:20 1995 Andrew Cagney <cagney@highland.com.au> 1779 1780 * debug.h, debug.c (trace_option): New function. Parses the trace 1781 option, updating the trace array. 1782 1783 * debug.h, debug.c (trace_usage): New function. Outputs the list 1784 of all possible trace options. 1785 1786 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to 1787 parse trace options specified with the simpler -t flag. Adjust 1788 usage. 1789 1790 * FIXME: basic parsing of command line options is still duplicated 1791 by main.c and sim_calls.c 1792 1793Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com> 1794 1795 * Makefile.in (clean): Delete *.i and *.out files. 1796 1797 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP 1798 macros for either assignment or return. Fix SWAP_8 to use a 1799 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now. 1800 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs 1801 that hardwired swapping on/off, let optimizer delete dead code. 1802 1803 * main.c (main): Add printf that we caught a signal and print out 1804 the failing address. 1805 1806Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com> 1807 1808 * Makefile.in: Remove tabs from otherwise empty line. 1809 Confuses many non-GNU versions of "make". 1810 1811Wed Oct 18 08:51:25 1995 Michael Meissner <meissner@tiktok.cygnus.com> 1812 1813 * Makefile.in (clean): Delete files produced by gen. 1814 1815Mon Oct 16 17:34:24 1995 Michael Meissner <meissner@tiktok.cygnus.com> 1816 1817 * gen.c (lf_print_c_semantic_function): Move counting # of 1818 instructions here so it works with caching. 1819 (gen_idecode_c): Move from here. 1820 1821Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au> 1822 1823 * gen.c, ppc-instructions, psim.c: Fix code for generating 1824 cracking instruction cache. Delete the code that cached just the 1825 result from doing an instruction lookup - this ran slower than no 1826 cache at all. 1827 1828Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com> 1829 1830 * Makefile.in (gen.o): Include $(INLINE_CFLAGS). 1831 1832 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with 1833 TCL when gdb is linked with the simulator. 1834 * debug.c (ppc_trace): Ditto. 1835 * sim_calls.c (sim_open): Change trace -> ppc_trace. 1836 * main.c (main): Ditto. 1837 1838 * cpu.c (cpu_add_commas): Remove extra static. 1839 1840Thu Oct 12 11:35:53 1995 Michael Meissner <meissner@tiktok.cygnus.com> 1841 1842 * Makefile.in (psim.o): Now that inlines are turned on, make 1843 psim.o depend on all sources. 1844 1845 * cpu.c (cpu_add_commas): New function to format a long with 1846 commas. 1847 (cpu_print_info): Use it to print number_of_insns. 1848 1849 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for 1850 2, 4, and 8 bytes. 1851 (ENDIAN_N): If both target and host byte orders are known, don't 1852 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER. 1853 1854 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0 1855 to allow target specific H2T_n/T2H_n macros to be used. 1856 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is 1857 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead 1858 of the 3 instruction sequence that runs on 386s. 1859 1860 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if 1861 specified on the compile line. 1862 (WITH_BSWAP): If not defined, define as 0. 1863 1864 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add 1865 default inline support. Pass INLINE_CFLAGS when compiling. 1866 1867 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not 1868 INLINE_DEVICES since GCC doesn't like inline functions that 1869 accept variable arguments. 1870 (stack_ioctl_callback): Make function just static because GCC 1871 doesn't like inline functions that accept variable arguments. 1872 1873 * devices.h (STATIC_DEVICES): Define as empty if not defined. 1874 1875 * inline.c: Correct pathnames of included C files to match current 1876 implementation. 1877 1878 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be 1879 non-zero, define STATIC_DEVICES to be static. 1880 1881 * std-config.h (INLINE): If GNU C and optimizing, define this as 1882 __inline__. 1883 (DEFAULT_INLINE): If not defined, define as 0. 1884 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE. 1885 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto. 1886 ({SPREG,IDECODE}_INLINE): Ditto. 1887 1888Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au> 1889 1890 * ppc-instructions: Initial cut of floating point suport added. 1891 Of note include - use of host IEEE floating point instructions, 1892 use of PowerPC manual pseudo code to handle the FPSCR. It is not 1893 currently a pretty sight. 1894 1895 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c: 1896 merge into core.h, core.c, core_n.h. The type memory_map replaced 1897 with core_map. This removes a level of pointer indirection when 1898 translating an address. 1899 1900 * memory_map.h, memory_map.c, memory_map_n.h: delete. 1901 1902 * Makefile.in et.al (sorry): tweek to use new core, core_map and 1903 core.h. 1904 1905Wed Oct 11 12:10:26 1995 Andrew Cagney <cagney@highland.com.au> 1906 1907 * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to 1908 most of the other functions in sim_calls.c. 1909 1910 * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in: 1911 Add macros to better cover up `generic' code. Makes it possible 1912 to step through the generic code! 1913 1914 * vm.c, vm_n.h, Makefile.in: ditto 1915 1916Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au> 1917 1918 * devices.h, devices.c, memory_map.h, memory_map.c: Changed 1919 callback interface so that there is a read/write buffer but no 1920 read/write_word. VEA default memory read/write handler sometimes 1921 couldn't resolve an access and of those some were for a memory 1922 fault and some were because gdb was making a bogus request. 1923 1924 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c: 1925 eliminate transfer_mode (raw or cooked) parameter from read/write 1926 buffer. 1927 1928Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au> 1929 1930 * ppc-instructions (fmul, fmuls): correct instruction format - had 1931 FRB instead of FRC. 1932 1933Wed Oct 4 17:31:12 1995 Andrew Cagney <cagney@highland.com.au> 1934 1935 * psim.c, device_tree.h, device_tree.c, devices.c (printd_*, 1936 scand_*): new functions to parse/print fields in device names 1937 while hiding any machine dependency. 1938 1939 * devices.c, psim.c: Change the stack init code so that it is 1940 handled by a device. Arguments passed across using a device ioctl 1941 (hack). 1942 1943 * devices.h, devices.c: device ioctl callback changed to allow a 1944 variable number of arguments. This gives greater flexability and 1945 greater chance of bugs. 1946 1947Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au> 1948 1949 * main.c (printf_filtered, error): Missing va_end() to close off 1950 variable argument use. 1951 1952 * Makefile.in (tmp-gencode): comment out hack to get around some 1953 versions of make not handling files being created as side-effects. 1954 1955 * gen.c (lf_open): Add -n (real_file_name) option.
