605 and code for spa, no longer to be used.
607 * psim.c (create_chirp_device_tree): Fill out what was previously
608 the openboot create function so that it starts to create a full
609 OpenBoot device tree.
611 Tue Nov 28 21:48:06 1995 Andrew Cagney <cagney@highland.com.au>

702 defined in lf_print_c_extraction.
703 (main): Recognize -R.

760 Sun Nov 19 23:00:52 1995 Michael Meissner <meissner@tiktok.cygnus.com>
762 * ppc-instructions (model data, model_busy): Rather than using a
763 bit mask for the busy units, just use a char array. Also, only
764 support 2 function units an insn can use, rather than a loop.
766 Fri Nov 17 14:08:08 1995 Michael Meissner <meissner@tiktok.cygnus.com>
768 * table.c (table_entry_read): Move setting entry->line_nr to after

773 before calling the model functions.
775 * debug.c (trace_descriptor): Add trace_model support.

827 * configure{,.in}: Ditto.
828 * Makefile.in: Ditto.

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.
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.
846 Wed Nov 15 17:32:13 1995 Michael Meissner <meissner@tiktok.cygnus.com>
848 * cpu.h (cpu_model): Add declaration.

916 Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
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.
923 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
926 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
927 Firstly make them errors and secondly remove the options gcc-245
930 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
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().
937 * emul_netbsd.c (write_direntries), psim.c (psim_read_register,
938 psim_write_register): replace bcopy() with memcpy().
940 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
942 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
943 force DEFAULT_INLINE to 0 rather then trusting the std
946 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
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.
952 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
953 of a boolean switch statement (field zero or non-zero).
955 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
956 switch/table generation ability of igen.
958 * igen.c (idecode_switch_leaf): Fix code output when a switch
959 statement needs to look up a table.
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.
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
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.
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.
991 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
992 and moved to insn_table_find_opcode_field.
994 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
996 * igen.c (model_c_insn): Suggestion - document the name of the
997 instruction on each line of the instruction model table.
999 Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au>
1001 * emul_netbsd.c (do_ioctl): Cleanup compilation.
1003 * sim_callbacks.h (__attribute__): Only define if not defined (was
1004 already defined on NetBSD host).

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.
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).
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.
1021 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
1022 Hopefully added correct hack to handle XOR endian mode.
1024 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
1025 little endian mode, the model accepts miss aligned transfers.
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
1032 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
1034 * devices.c (halt_io_write_buffer_callback): Use value written to
1035 halt device to determine exit status. Thus allowing
1036 success/failure of OEA tests.
1038 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>
1040 * ppc-instructions (icbi): If icache present flush it.
1042 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
1044 * devices.c (htab_init_callback): Add code to create htab/pte.
1046 * devices.c (dma_file, file_init_callback, htab_init_callback):
1047 New function - Dma the named file into memory at the specified
1050 * device_tree.h, device_tree.c (scand_*): New functions.
1052 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
1054 * filter_filename.c, Makefile.in: Change so that only dependant on
1055 a very limited nr of files. Stops an unnecessary dependency.
1057 Tue Nov 7 15:44:33 1995 Andrew Cagney <cagney@highland.com.au>
1059 * core.c (core_map_find_mapping): Use cpu_halt rather than error
1060 to abort an access to an undefined address.

1072 * ppc-instructions (model_{start,halt,print_info}): Add dummy
1075 * options.c (print_options): Print out WITH_{,DEFAULT_}MODEL, not
1076 WITH_PPC_{,DEFAULT_}_MODEL.
1077 (options_ppc): Delete now unused function.
1078 (cpu.h): Include cpu.h, not just basics.h.
1080 * std-config.h (WITH_{,DEFAULT_}MODEL): Define.
1082 * igen.c (model_macros, last_model_macro): New statics to keep
1083 track of macros to go in model.h.

1086 (model_table_fields): Add field for printable name.
1087 (gen_model_h): If there are model macros defined, print them out.
1088 Print out DEFAULT_MODEL as the first model if there any models
1089 specified, otherwise MODEL_NONE. Print out external decl for
1090 current_model. Print out decl for model_set.
1091 (gen_model_c): Add function model_set. Switch to use printable
1092 name for the model, not the internal identifier used.
1094 * psim.c (current_model): New global variable.
1096 * ppc-instructions: Add macros for flag defines. Switch first
1097 model so 604 is first.
1099 * main.c (main): Call model_set, not function_unit_model.
1100 * sim_calls.c (sim_open): Ditto.
1101 * sim_calls.c, Makefile.in: sim_calls.c now includes cpu.h.

1109 * mon.c (mon_event): New function.
1110 (mon_print_info): Print icache misses.
1112 * psim.c (run_until_stop): Monitor icache misses.
1114 * configure.in (--enable-sim-inline): Fix typos in handling comma
1115 separated inline options.
1116 (--enable-sim-icache): Echo icache size.
1117 * configure: Regenerate.
1119 * igen.c (semantics_h_print_function): Emit STATIC_SEMANTICS
1120 instead of INLINE_SEMANTICS so that the compiler won't keep all of

1664 the processor is started. Fixes problem of registers being
1665 undefined when restarting from within gdb.
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.
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.
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
1681 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
1683 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance

1688 information is already available from the mon_issue() hook.
1690 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
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].
1697 Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au>
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).
1704 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
1706 * system.c: More system call emulation. If code appears NetBSD
1707 specific, make conditional to being compiled on a NetBSD system

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
1720 * NOTE: igen, since it was originally written for the
1721 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
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.
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.
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
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.

1745 * ppc-instructions (64 bit Store Double Word Conditional Indexed):
1746 bitrot - updated to use newer CR register operators.
1748 * ppc-instructions (64bit Floating Convert from Integer
1749 Doubleword): Correct call to Round_Float().
1751 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
1753 * basics.h: #include "sim_callbacks.h" earlier so that its
1754 prototypes are declared in all other header files.
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
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.
1764 Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au>
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.
1770 * device_tree.c, devices.h, devices.c: include path to device in a
1771 devices node when creating it.
1773 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.

1780 * debug.h, debug.c (trace_option): New function. Parses the trace
1781 option, updating the trace array.
1783 * debug.h, debug.c (trace_usage): New function. Outputs the list
1784 of all possible trace options.
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
1790 * FIXME: basic parsing of command line options is still duplicated
1791 by main.c and sim_calls.c
1793 Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1795 * Makefile.in (clean): Delete *.i and *.out files.
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.
1803 * main.c (main): Add printf that we caught a signal and print out
1804 the failing address.
1806 Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>
1808 * Makefile.in: Remove tabs from otherwise empty line.

1819 (gen_idecode_c): Move from here.
1821 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
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
1828 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1830 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
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.

1843 psim.o depend on all sources.
1845 * cpu.c (cpu_add_commas): New function to format a long with
1847 (cpu_print_info): Use it to print number_of_insns.
1849 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
1851 (ENDIAN_N): If both target and host byte orders are known, don't
1852 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
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.
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.
1864 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
1865 default inline support. Pass INLINE_CFLAGS when compiling.
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.
1873 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1875 * inline.c: Correct pathnames of included C files to match current
1878 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1879 non-zero, define STATIC_DEVICES to be static.
1881 * std-config.h (INLINE): If GNU C and optimizing, define this as
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.
1888 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
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.
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.
1900 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1902 * Makefile.in et.al (sorry): tweek to use new core, core_map and

1914 * vm.c, vm_n.h, Makefile.in: ditto
1916 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
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.
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
1928 Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>
1930 * ppc-instructions (fmul, fmuls): correct instruction format - had

1936 scand_*): new functions to parse/print fields in device names
1937 while hiding any machine dependency.
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
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.
1947 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
1949 * main.c (printf_filtered, error): Missing va_end() to close off
1950 variable argument use.
1952 * Makefile.in (tmp-gencode): comment out hack to get around some
1953 versions of make not handling files being created as side-effects.
1955 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
1956 alternative file name to use in output files for things like #line
1959 Makefile.in (tmp-gencode): Use gen -n so that debug info is
1962 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the

1982 At present, print the number of instructions executed.
1984 * gen_idecode_c: Emit call to cpu_increment_number_of_insns within
1987 * psim.c (psim_print_info): New function to iterate over each of
1988 the CPU's calling cpu_print_info.
1990 * psim.h,cpu.h: Add new declarations.
1992 * sim_calls.c (sim_open): Add argument processing to add the same
1993 switches main.c accepts for the standalone processor.
1994 (sim_close): Call psim_print_info if -I.
1996 * main.c (main): Add comment saying to update sim_calls.c when
1997 adding switches. Add -I to call psim_print_info when done.

2023 * device_tree.c (create_option_device_node): Assume a program is
2024 OEA if the start address is < 4096, not just == 0.

2073 wrong address (0) instead of &end.
2075 * core.c (core_add_stack, core_add_data): Was not handling case
2076 where bss/stack is grown across the current end-of-{bss,stack}.
2078 Wed Sep 6 00:46:10 1995 Andrew Cagney <cagney@highland.com.au>
2080 * system.c (system_call): Fix SYS_break - was aligning bss to a

2104 environment, and support compiling in a different directory than
2105 the sources reside in.
2107 * ppc-endian.h: Rename from endian.h so that it doesn't get
2108 confused with /usr/include/sys/endian.h on Linux. Add Linux
