648 defined in lf_print_c_extraction.
649 (main): Recognize -R.

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

788 instructions, rather than testing it in model_issue. Add code to
789 code successful/unsuccessful branch predictions, and the number of
790 conditional branches that fell through.
792 Wed Nov 15 17:32:13 1995 Michael Meissner <meissner@tiktok.cygnus.com>

862 Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
864 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
865 inline.. Only problem being that with ppc-opcode-simple this gave
866 it the chance to inline all the idecode functions with potentially
867 disasterous results on a 16mb PC. For moment hobble INLINE.
869 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
872 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
873 Firstly make them errors and secondly remove the options gcc-245
876 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
878 * misc.c (zalloc), cpu.c (cpu_init), devices
879 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
880 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
881 sim_calls.c (zalloc) : replace bzero() with memset().
883 * emul_netbsd.c (write_direntries), psim.c (psim_read_register,
884 psim_write_register): replace bcopy() with memcpy().
886 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
888 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
889 force DEFAULT_INLINE to 0 rather then trusting the std
892 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
894 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
895 generation of switch entries in tables - treat the same as
896 cracking/semantic functions.
898 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
899 of a boolean switch statement (field zero or non-zero).
901 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
902 switch/table generation ability of igen.
904 * igen.c (idecode_switch_leaf): Fix code output when a switch
905 statement needs to look up a table.
907 * igen.c (idecode_declare_if_switch): New function called from
908 gen_idecode_c - need to declare any idecode switch functions
909 before they are used in idecode tables.
911 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
912 idecode_crack_insn): Add is_inline_function argument to code
913 printing cracker functions which indicates if STATIC_IDECODE or
914 STATIC_INLINE_IDECODE should be used for definition. For
915 idecode_crack_insn (which implies not duplicating/expanding) don't
916 declare function as inline - we assume that the only time this is
917 code is generated is when things are being tested. For
918 idecode_crack_leaf, make static (instead of INLINE) if the
919 instructions parent is a table as function will always be called
922 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
923 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
924 called directly, all others are called via a table.
926 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
927 semantics_h_insn, semantics_h_function,
928 lf_print_c_semantic_function, semantics_c_function): Add
929 is_inline_function argument to lf_print_semantic_function_header
930 to indicate if an inline or static function declaration/definition
931 should be output. Depending on situtation call accordingly:
932 functions (not instruction semantic routines) are always inline;
933 Semantic routines are made inline when there is no icache (cache
934 will contain the function address) and are duplicating (see above)
935 and the parent of the instruction is a switch statement.
937 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
938 and moved to insn_table_find_opcode_field.
940 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
942 * igen.c (model_c_insn): Suggestion - document the name of the
943 instruction on each line of the instruction model table.
945 Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au>
947 * emul_netbsd.c (do_ioctl): Cleanup compilation.
949 * sim_callbacks.h (__attribute__): Only define if not defined (was
950 already defined on NetBSD host).
952 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
954 * std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New
955 macro, indicates if the PowerPC's horrible XOR endian mode should
956 be suported. Add to configure and make.
958 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
959 (vm_instruction_map_read): If XOR endian, xor the address
960 with a value from an xor table (indexed by size of access).
962 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
963 set up xor table to xor if there is a conflict between the
964 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
965 check of suported change of endian mode from cpu.c to vm.c.
967 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
968 Hopefully added correct hack to handle XOR endian mode.
970 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
971 little endian mode, the model accepts miss aligned transfers.
973 FIXME: Need to create an `init' device that, during
974 initializatioin for XOR mode, it mushes (XOR address) all the dma
975 data before passing it on to the core for storage. Just like the
978 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
980 * devices.c (halt_io_write_buffer_callback): Use value written to
981 halt device to determine exit status. Thus allowing
982 success/failure of OEA tests.
984 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>
986 * ppc-instructions (icbi): If icache present flush it.
988 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
990 * devices.c (htab_init_callback): Add code to create htab/pte.
992 * devices.c (dma_file, file_init_callback, htab_init_callback):
993 New function - Dma the named file into memory at the specified
996 * device_tree.h, device_tree.c (scand_*): New functions.
998 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
1000 * filter_filename.c, Makefile.in: Change so that only dependant on
1001 a very limited nr of files. Stops an unnecessary dependency.
1003 Tue Nov 7 15:44:33 1995 Andrew Cagney <cagney@highland.com.au>
1005 * core.c (core_map_find_mapping): Use cpu_halt rather than error
1006 to abort an access to an undefined address.

1024 (cpu.h): Include cpu.h, not just basics.h.
1026 * std-config.h (WITH_{,DEFAULT_}MODEL): Define.

1037 (gen_model_c): Add function model_set. Switch to use printable
1038 name for the model, not the internal identifier used.
1040 * psim.c (current_model): New global variable.
1042 * ppc-instructions: Add macros for flag defines. Switch first
1043 model so 604 is first.

1063 * configure: Regenerate.
1065 * igen.c (semantics_h_print_function): Emit STATIC_SEMANTICS
1066 instead of INLINE_SEMANTICS so that the compiler won't keep all of
1067 the semantic functions as inline RTL, given that the address of
1068 the function is taken which forces outline calls anyway.

1405 * Makefile.in: Uncomment built file dependencies.
1407 * configure.in: Rewrite --enable-sim switch handling to use the

1489 * ppc-opcode-stupid: Third example of use of opcode table - this
1490 one expands all mtspr/mfspr and branch instructions. Appears to

1556 and optimizing by default.
1558 Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au>
1560 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
1561 make them functions again. Appears 2.6.3 is confused by just a
1564 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
1566 * ppc-endian.c (SWAP_8): Fix 8 byte swap!

1569 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
1570 matched the compiled in ones.
1572 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
1573 trace_semantics is now different to trace_idecode, the former

1589 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
1590 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
1591 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
1592 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
1593 the instruction or data critical paths.
1595 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
1596 the inclusion of device_tree.c/emul_generic.c.
1598 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
1600 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace

1614 instruction cache (if present). Fixes problem of cpu caching gdb
1615 breakpoint instructions.
1617 FIXME: PSIM sometimes aborts calling error(), it should instead
1618 call sim_error() say which takes care of housekeeping such as
1619 saving the CIA before calling error.
1621 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
1622 used when restarting a simulation because the latter has the
1623 unwanted side effect (well I as a kernel hacker think it is) of
1624 performing an isync when the instruction stream doesn't contain
1627 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
1629 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
1630 monitoring module. Counts both instructions issued and
1633 * NOTE: mon does not contain to count instruction loads as this
1634 information is already available from the mon_issue() hook.

1645 * sim_calls.c, main.c, psim.c (psim_create): always create
1646 `WITH_SMP' cpus. The actual number of CPU's active in a
1647 simulation run is taken from the device node: /init/smp (an
1648 integer). WITH_SMP changed to 2 (remember to put it back to 0).
1650 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
1652 * system.c: More system call emulation. If code appears NetBSD

1659 lf.[ch](new), table.[ch](new): Split into two generators - igen
1660 that outputs the instruction tables and dgen that outputs the spr
1661 tables. Add -f (filter out) flag to igen to filter out certain
1662 instructions (ex 64 bit ones) from the created tables. Include
1663 $(LIBIBERTY_LIB) in link options in case host lacks some libc
1666 * NOTE: igen, since it was originally written for the
1667 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
1669 * Makefile.in, std-config.h, ppc-cache-rules(new),
1670 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
1671 cache-rule and opcode-rule tables from macros found std-config.h.
1672 Delete corresponding macro's from std-config.h.
1674 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
1675 an table of all the instructions. Code to output a type
1676 enumerating all the instructin names.
1678 * igen.c(lf_print_c_semantic): Move call to increment instruction
1679 counter so that it occures _after_ the instruction has been fully
1680 validated, was double counting illegal/invalid instructions. Add
1681 conditional so only compiled in when WITH_PROFILE enabled (enabled
1684 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
1685 itable.h, count individual instruction types not just total,

1692 bitrot - updated to use newer CR register operators.
1694 * ppc-instructions (64bit Floating Convert from Integer
1695 Doubleword): Correct call to Round_Float().
1697 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
1699 * basics.h: #include "sim_callbacks.h" earlier so that its
1700 prototypes are declared in all other header files.
1702 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
1703 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into

1707 Add size of buffer argument to functions writing a string into a
1708 buffer. Check for buffer overflow.
1710 Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au>
1712 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing
1713 of each device. Make parameter names consistent so macros work.

1726 * debug.h, debug.c (trace_option): New function. Parses the trace
1727 option, updating the trace array.
1729 * debug.h, debug.c (trace_usage): New function. Outputs the list
1730 of all possible trace options.
1732 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
1733 parse trace options specified with the simpler -t flag. Adjust
1736 * FIXME: basic parsing of command line options is still duplicated
1737 by main.c and sim_calls.c

1741 * Makefile.in (clean): Delete *.i and *.out files.
1743 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
1744 macros for either assignment or return. Fix SWAP_8 to use a
1745 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
1746 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
1747 that hardwired swapping on/off, let optimizer delete dead code.
1749 * main.c (main): Add printf that we caught a signal and print out
1750 the failing address.
1752 Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>

1770 cracking instruction cache. Delete the code that cached just the
1771 result from doing an instruction lookup - this ran slower than no
1774 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1776 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).

1793 (cpu_print_info): Use it to print number_of_insns.
1795 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
1797 (ENDIAN_N): If both target and host byte orders are known, don't
1798 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
1800 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
1801 to allow target specific H2T_n/T2H_n macros to be used.
1802 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
1803 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
1804 of the 3 instruction sequence that runs on 386s.
1806 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
1807 specified on the compile line.
1808 (WITH_BSWAP): If not defined, define as 0.

1811 default inline support. Pass INLINE_CFLAGS when compiling.
1813 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
1814 INLINE_DEVICES since GCC doesn't like inline functions that
1815 accept variable arguments.
1816 (stack_ioctl_callback): Make function just static because GCC
1817 doesn't like inline functions that accept variable arguments.
1819 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1821 * inline.c: Correct pathnames of included C files to match current
1824 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1825 non-zero, define STATIC_DEVICES to be static.
1827 * std-config.h (INLINE): If GNU C and optimizing, define this as
1829 (DEFAULT_INLINE): If not defined, define as 0.
1830 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1831 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
1832 ({SPREG,IDECODE}_INLINE): Ditto.
1834 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1836 * ppc-instructions: Initial cut of floating point suport added.
1837 Of note include - use of host IEEE floating point instructions,
1838 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1839 currently a pretty sight.
1841 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1842 merge into core.h, core.c, core_n.h. The type memory_map replaced
1843 with core_map. This removes a level of pointer indirection when
1844 translating an address.
1846 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1848 * Makefile.in et.al (sorry): tweek to use new core, core_map and

1862 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
1864 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1865 callback interface so that there is a read/write buffer but no
1866 read/write_word. VEA default memory read/write handler sometimes
1867 couldn't resolve an access and of those some were for a memory
1868 fault and some were because gdb was making a bogus request.
1870 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
1871 eliminate transfer_mode (raw or cooked) parameter from read/write
1874 Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>
1876 * ppc-instructions (fmul, fmuls): correct instruction format - had

1886 handled by a device. Arguments passed across using a device ioctl
1889 * devices.h, devices.c: device ioctl callback changed to allow a
1890 variable number of arguments. This gives greater flexability and
1891 greater chance of bugs.
1893 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
1895 * main.c (printf_filtered, error): Missing va_end() to close off
1896 variable argument use.
1898 * Makefile.in (tmp-gencode): comment out hack to get around some
1899 versions of make not handling files being created as side-effects.
1901 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
1902 alternative file name to use in output files for things like #line
1905 Makefile.in (tmp-gencode): Use gen -n so that debug info is
1908 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the

1928 At present, print the number of instructions executed.
1930 * gen_idecode_c: Emit call to cpu_increment_number_of_insns within
1933 * psim.c (psim_print_info): New function to iterate over each of
1934 the CPU's calling cpu_print_info.
1936 * psim.h,cpu.h: Add new declarations.

1939 switches main.c accepts for the standalone processor.
1940 (sim_close): Call psim_print_info if -I.
1942 * main.c (main): Add comment saying to update sim_calls.c when
