676 defined in lf_print_c_extraction.
677 (main): Recognize -R.

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

802 * Makefile.in: Ditto.

816 instructions, rather than testing it in model_issue. Add code to
817 code successful/unsuccessful branch predictions, and the number of
818 conditional branches that fell through.
820 Wed Nov 15 17:32:13 1995 Michael Meissner <meissner@tiktok.cygnus.com>
822 * cpu.h (cpu_model): Add declaration.

890 Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
892 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
893 inline.. Only problem being that with ppc-opcode-simple this gave
894 it the chance to inline all the idecode functions with potentially
895 disasterous results on a 16mb PC. For moment hobble INLINE.
897 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
900 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
901 Firstly make them errors and secondly remove the options gcc-245
904 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
906 * misc.c (zalloc), cpu.c (cpu_init), devices
907 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
908 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
909 sim_calls.c (zalloc) : replace bzero() with memset().
911 * emul_netbsd.c (write_direntries), psim.c (psim_read_register,
912 psim_write_register): replace bcopy() with memcpy().
914 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
916 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
917 force DEFAULT_INLINE to 0 rather then trusting the std
920 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
922 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
923 generation of switch entries in tables - treat the same as
924 cracking/semantic functions.
926 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
927 of a boolean switch statement (field zero or non-zero).
929 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
930 switch/table generation ability of igen.
932 * igen.c (idecode_switch_leaf): Fix code output when a switch
933 statement needs to look up a table.
935 * igen.c (idecode_declare_if_switch): New function called from
936 gen_idecode_c - need to declare any idecode switch functions
937 before they are used in idecode tables.
939 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
940 idecode_crack_insn): Add is_inline_function argument to code
941 printing cracker functions which indicates if STATIC_IDECODE or
942 STATIC_INLINE_IDECODE should be used for definition. For
943 idecode_crack_insn (which implies not duplicating/expanding) don't
944 declare function as inline - we assume that the only time this is
945 code is generated is when things are being tested. For
946 idecode_crack_leaf, make static (instead of INLINE) if the
947 instructions parent is a table as function will always be called
950 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
951 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
952 called directly, all others are called via a table.
954 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
955 semantics_h_insn, semantics_h_function,
956 lf_print_c_semantic_function, semantics_c_function): Add
957 is_inline_function argument to lf_print_semantic_function_header
958 to indicate if an inline or static function declaration/definition
959 should be output. Depending on situtation call accordingly:
960 functions (not instruction semantic routines) are always inline;
961 Semantic routines are made inline when there is no icache (cache
962 will contain the function address) and are duplicating (see above)
963 and the parent of the instruction is a switch statement.
965 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
966 and moved to insn_table_find_opcode_field.
968 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
970 * igen.c (model_c_insn): Suggestion - document the name of the
971 instruction on each line of the instruction model table.
973 Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au>
975 * emul_netbsd.c (do_ioctl): Cleanup compilation.
977 * sim_callbacks.h (__attribute__): Only define if not defined (was
978 already defined on NetBSD host).

982 * std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New
983 macro, indicates if the PowerPC's horrible XOR endian mode should
984 be suported. Add to configure and make.
986 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
987 (vm_instruction_map_read): If XOR endian, xor the address
988 with a value from an xor table (indexed by size of access).
990 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
991 set up xor table to xor if there is a conflict between the
992 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
993 check of suported change of endian mode from cpu.c to vm.c.
995 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
996 Hopefully added correct hack to handle XOR endian mode.
998 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
999 little endian mode, the model accepts miss aligned transfers.
1001 FIXME: Need to create an `init' device that, during
1002 initializatioin for XOR mode, it mushes (XOR address) all the dma
1003 data before passing it on to the core for storage. Just like the
1006 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
1008 * devices.c (halt_io_write_buffer_callback): Use value written to
1009 halt device to determine exit status. Thus allowing
1010 success/failure of OEA tests.
1012 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>
1014 * ppc-instructions (icbi): If icache present flush it.
1016 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
1018 * devices.c (htab_init_callback): Add code to create htab/pte.
1020 * devices.c (dma_file, file_init_callback, htab_init_callback):
1021 New function - Dma the named file into memory at the specified
1024 * device_tree.h, device_tree.c (scand_*): New functions.
1026 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
1028 * filter_filename.c, Makefile.in: Change so that only dependant on
1029 a very limited nr of files. Stops an unnecessary dependency.
1031 Tue Nov 7 15:44:33 1995 Andrew Cagney <cagney@highland.com.au>
1033 * core.c (core_map_find_mapping): Use cpu_halt rather than error
1034 to abort an access to an undefined address.

1051 (options_ppc): Delete now unused function.
1052 (cpu.h): Include cpu.h, not just basics.h.
1054 * std-config.h (WITH_{,DEFAULT_}MODEL): Define.

1065 (gen_model_c): Add function model_set. Switch to use printable
1066 name for the model, not the internal identifier used.
1068 * psim.c (current_model): New global variable.
1070 * ppc-instructions: Add macros for flag defines. Switch first
1071 model so 604 is first.
1073 * main.c (main): Call model_set, not function_unit_model.
1074 * sim_calls.c (sim_open): Ditto.
1075 * sim_calls.c, Makefile.in: sim_calls.c now includes cpu.h.

1091 * configure: Regenerate.
1093 * igen.c (semantics_h_print_function): Emit STATIC_SEMANTICS
1094 instead of INLINE_SEMANTICS so that the compiler won't keep all of
1095 the semantic functions as inline RTL, given that the address of
1096 the function is taken which forces outline calls anyway.

1433 * Makefile.in: Uncomment built file dependencies.
1435 * configure.in: Rewrite --enable-sim switch handling to use the

1588 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
1589 make them functions again. Appears 2.6.3 is confused by just a
1592 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
1594 * ppc-endian.c (SWAP_8): Fix 8 byte swap!

1600 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
1601 trace_semantics is now different to trace_idecode, the former

1606 * ppc-instructions (mtsrin): Missing instruction
1607 * ppc-instructions (mfsrin): Missing instruction

1619 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
1620 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
1621 the instruction or data critical paths.
1623 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
1624 the inclusion of device_tree.c/emul_generic.c.

1642 instruction cache (if present). Fixes problem of cpu caching gdb
1643 breakpoint instructions.
1645 FIXME: PSIM sometimes aborts calling error(), it should instead
1646 call sim_error() say which takes care of housekeeping such as
1647 saving the CIA before calling error.
1649 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
1650 used when restarting a simulation because the latter has the
1651 unwanted side effect (well I as a kernel hacker think it is) of
1652 performing an isync when the instruction stream doesn't contain
1655 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
1657 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
1658 monitoring module. Counts both instructions issued and

1671 Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au>
1673 * sim_calls.c, main.c, psim.c (psim_create): always create
1674 `WITH_SMP' cpus. The actual number of CPU's active in a
1675 simulation run is taken from the device node: /init/smp (an
1676 integer). WITH_SMP changed to 2 (remember to put it back to 0).
1678 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
1680 * system.c: More system call emulation. If code appears NetBSD

1688 that outputs the instruction tables and dgen that outputs the spr
1689 tables. Add -f (filter out) flag to igen to filter out certain
1690 instructions (ex 64 bit ones) from the created tables. Include
1691 $(LIBIBERTY_LIB) in link options in case host lacks some libc
1694 * NOTE: igen, since it was originally written for the
1695 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
1697 * Makefile.in, std-config.h, ppc-cache-rules(new),
1698 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
1699 cache-rule and opcode-rule tables from macros found std-config.h.
1700 Delete corresponding macro's from std-config.h.
1702 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
1703 an table of all the instructions. Code to output a type
1704 enumerating all the instructin names.
1706 * igen.c(lf_print_c_semantic): Move call to increment instruction
1707 counter so that it occures _after_ the instruction has been fully
1708 validated, was double counting illegal/invalid instructions. Add
1709 conditional so only compiled in when WITH_PROFILE enabled (enabled
1712 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
1713 itable.h, count individual instruction types not just total,

1722 * ppc-instructions (64bit Floating Convert from Integer
1723 Doubleword): Correct call to Round_Float().
1725 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
1727 * basics.h: #include "sim_callbacks.h" earlier so that its
1728 prototypes are declared in all other header files.
1730 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
1731 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into

1754 * debug.h, debug.c (trace_option): New function. Parses the trace
1755 option, updating the trace array.
1757 * debug.h, debug.c (trace_usage): New function. Outputs the list
1758 of all possible trace options.
1760 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
1761 parse trace options specified with the simpler -t flag. Adjust
1764 * FIXME: basic parsing of command line options is still duplicated
1765 by main.c and sim_calls.c

1769 * Makefile.in (clean): Delete *.i and *.out files.
1771 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
1772 macros for either assignment or return. Fix SWAP_8 to use a
1773 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
1774 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
1775 that hardwired swapping on/off, let optimizer delete dead code.
1777 * main.c (main): Add printf that we caught a signal and print out
1778 the failing address.
1780 Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>

1798 cracking instruction cache. Delete the code that cached just the
1799 result from doing an instruction lookup - this ran slower than no
1802 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1804 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).

1821 (cpu_print_info): Use it to print number_of_insns.
1823 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
1825 (ENDIAN_N): If both target and host byte orders are known, don't
1826 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
1828 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
1829 to allow target specific H2T_n/T2H_n macros to be used.
1830 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
1831 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
1832 of the 3 instruction sequence that runs on 386s.
1834 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
1835 specified on the compile line.
1836 (WITH_BSWAP): If not defined, define as 0.

1839 default inline support. Pass INLINE_CFLAGS when compiling.
1841 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
1842 INLINE_DEVICES since GCC doesn't like inline functions that
1843 accept variable arguments.
1844 (stack_ioctl_callback): Make function just static because GCC
1845 doesn't like inline functions that accept variable arguments.
1847 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1849 * inline.c: Correct pathnames of included C files to match current
1852 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1853 non-zero, define STATIC_DEVICES to be static.
1855 * std-config.h (INLINE): If GNU C and optimizing, define this as
1857 (DEFAULT_INLINE): If not defined, define as 0.
1858 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1859 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.

1864 * ppc-instructions: Initial cut of floating point suport added.
1865 Of note include - use of host IEEE floating point instructions,
1866 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1867 currently a pretty sight.
1869 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1870 merge into core.h, core.c, core_n.h. The type memory_map replaced
1871 with core_map. This removes a level of pointer indirection when
1872 translating an address.
1874 * memory_map.h, memory_map.c, memory_map_n.h: delete.

1890 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
1892 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1893 callback interface so that there is a read/write buffer but no
1894 read/write_word. VEA default memory read/write handler sometimes
1895 couldn't resolve an access and of those some were for a memory
1896 fault and some were because gdb was making a bogus request.
1898 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
1899 eliminate transfer_mode (raw or cooked) parameter from read/write

1914 handled by a device. Arguments passed across using a device ioctl
1917 * devices.h, devices.c: device ioctl callback changed to allow a
1918 variable number of arguments. This gives greater flexability and
1919 greater chance of bugs.
1921 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
1923 * main.c (printf_filtered, error): Missing va_end() to close off
1924 variable argument use.
1926 * Makefile.in (tmp-gencode): comment out hack to get around some
1927 versions of make not handling files being created as side-effects.
1929 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
1930 alternative file name to use in output files for things like #line
1933 Makefile.in (tmp-gencode): Use gen -n so that debug info is
1936 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the

1956 At present, print the number of instructions executed.
1958 * gen_idecode_c: Emit call to cpu_increment_number_of_insns within
1961 * psim.c (psim_print_info): New function to iterate over each of
1962 the CPU's calling cpu_print_info.
1964 * psim.h,cpu.h: Add new declarations.
1966 * sim_calls.c (sim_open): Add argument processing to add the same
1967 switches main.c accepts for the standalone processor.
1968 (sim_close): Call psim_print_info if -I.
1970 * main.c (main): Add comment saying to update sim_calls.c when
1971 adding switches. Add -I to call psim_print_info when done.

1997 * device_tree.c (create_option_device_node): Assume a program is
1998 OEA if the start address is < 4096, not just == 0.

2049 * core.c (core_add_stack, core_add_data): Was not handling case
2050 where bss/stack is grown across the current end-of-{bss,stack}.
2052 Wed Sep 6 00:46:10 1995 Andrew Cagney <cagney@highland.com.au>
2054 * system.c (system_call): Fix SYS_break - was aligning bss to a
