295 functions either return -1 or zero so unsigned was a bit
298 * inline.h (*), igen.c, dgen.c, *: Update INLINE macros so that
299 they are paramaterised with the type of the function. Gets around
300 the problem of `static' needing to come first with `attribute'
301 comming last. Format declarations and definitions so that emacs

434 * basics.h (__attribute__), sim_callbacks.h: Move attribute macro
435 to basics.h and add hack (include <stdio.h>) to try and bring that
436 and other possible conflicting macros into scope much earler.

634 defined in lf_print_c_extraction.
635 (main): Recognize -R.

694 * ppc-instructions (model data, model_busy): Rather than using a
695 bit mask for the busy units, just use a char array. Also, only
696 support 2 function units an insn can use, rather than a loop.
698 Fri Nov 17 14:08:08 1995 Michael Meissner <meissner@tiktok.cygnus.com>
700 * table.c (table_entry_read): Move setting entry->line_nr to after

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

848 Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
850 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
851 inline.. Only problem being that with ppc-opcode-simple this gave
852 it the chance to inline all the idecode functions with potentially
853 disasterous results on a 16mb PC. For moment hobble INLINE.
855 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
858 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
859 Firstly make them errors and secondly remove the options gcc-245
862 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
864 * misc.c (zalloc), cpu.c (cpu_init), devices
865 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
866 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
867 sim_calls.c (zalloc) : replace bzero() with memset().
869 * emul_netbsd.c (write_direntries), psim.c (psim_read_register,
870 psim_write_register): replace bcopy() with memcpy().
872 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
874 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
875 force DEFAULT_INLINE to 0 rather then trusting the std
878 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
880 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
881 generation of switch entries in tables - treat the same as
882 cracking/semantic functions.
884 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
885 of a boolean switch statement (field zero or non-zero).
887 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
888 switch/table generation ability of igen.
890 * igen.c (idecode_switch_leaf): Fix code output when a switch
891 statement needs to look up a table.
893 * igen.c (idecode_declare_if_switch): New function called from

895 before they are used in idecode tables.
897 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
898 idecode_crack_insn): Add is_inline_function argument to code
899 printing cracker functions which indicates if STATIC_IDECODE or
900 STATIC_INLINE_IDECODE should be used for definition. For
901 idecode_crack_insn (which implies not duplicating/expanding) don't
902 declare function as inline - we assume that the only time this is
903 code is generated is when things are being tested. For
904 idecode_crack_leaf, make static (instead of INLINE) if the
905 instructions parent is a table as function will always be called
908 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
909 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
910 called directly, all others are called via a table.
912 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
913 semantics_h_insn, semantics_h_function,
914 lf_print_c_semantic_function, semantics_c_function): Add
915 is_inline_function argument to lf_print_semantic_function_header
916 to indicate if an inline or static function declaration/definition
917 should be output. Depending on situtation call accordingly:
918 functions (not instruction semantic routines) are always inline;
919 Semantic routines are made inline when there is no icache (cache
920 will contain the function address) and are duplicating (see above)
921 and the parent of the instruction is a switch statement.
923 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
924 and moved to insn_table_find_opcode_field.
926 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
928 * igen.c (model_c_insn): Suggestion - document the name of the
929 instruction on each line of the instruction model table.
931 Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au>
933 * emul_netbsd.c (do_ioctl): Cleanup compilation.
935 * sim_callbacks.h (__attribute__): Only define if not defined (was
936 already defined on NetBSD host).

940 * std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New
941 macro, indicates if the PowerPC's horrible XOR endian mode should
942 be suported. Add to configure and make.
944 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
945 (vm_instruction_map_read): If XOR endian, xor the address
946 with a value from an xor table (indexed by size of access).
948 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
949 set up xor table to xor if there is a conflict between the
950 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
951 check of suported change of endian mode from cpu.c to vm.c.
953 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
954 Hopefully added correct hack to handle XOR endian mode.
956 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
957 little endian mode, the model accepts miss aligned transfers.
959 FIXME: Need to create an `init' device that, during
960 initializatioin for XOR mode, it mushes (XOR address) all the dma
961 data before passing it on to the core for storage. Just like the
964 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
966 * devices.c (halt_io_write_buffer_callback): Use value written to
967 halt device to determine exit status. Thus allowing
968 success/failure of OEA tests.
970 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>
972 * ppc-instructions (icbi): If icache present flush it.
974 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
976 * devices.c (htab_init_callback): Add code to create htab/pte.
978 * devices.c (dma_file, file_init_callback, htab_init_callback):
979 New function - Dma the named file into memory at the specified
982 * device_tree.h, device_tree.c (scand_*): New functions.
984 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
986 * filter_filename.c, Makefile.in: Change so that only dependant on
987 a very limited nr of files. Stops an unnecessary dependency.
989 Tue Nov 7 15:44:33 1995 Andrew Cagney <cagney@highland.com.au>
991 * core.c (core_map_find_mapping): Use cpu_halt rather than error
992 to abort an access to an undefined address.

1023 (gen_model_c): Add function model_set. Switch to use printable
1024 name for the model, not the internal identifier used.
1026 * psim.c (current_model): New global variable.
1028 * ppc-instructions: Add macros for flag defines. Switch first
1029 model so 604 is first.

1032 * sim_calls.c (sim_open): Ditto.
1033 * sim_calls.c, Makefile.in: sim_calls.c now includes cpu.h.

1049 * configure: Regenerate.
1051 * igen.c (semantics_h_print_function): Emit STATIC_SEMANTICS
1052 instead of INLINE_SEMANTICS so that the compiler won't keep all of
1053 the semantic functions as inline RTL, given that the address of
1054 the function is taken which forces outline calls anyway.

1391 * Makefile.in: Uncomment built file dependencies.
1393 * configure.in: Rewrite --enable-sim switch handling to use the

1426 * mon.c (mon_print_info): Align the cpu number and number of
1427 instructions fields. Do not print an instruction category if the
1428 CPU did not execute any of those instructions. Print out number
1429 of reads and writes. If getrusage is supported, print out number
1430 of simulated instructins per second.
1432 * configure.in: Add support for --enable-sim-opcode=stupid.
1433 * configure: Regenerate.

1473 Tue Oct 31 21:31:32 1995 Andrew Cagney <cagney@highland.com.au>
1475 * ppc-opcode-stupid: Third example of use of opcode table - this
1476 one expands all mtspr/mfspr and branch instructions. Appears to
1477 give about a 10% gain in performance if everything enabled. Also
1478 takes about 150mb of swap to build.

1535 and --enable-sim-endian switch to control various Makefile
1537 * configure: Regenerate from configure.in.
1538 * Makefile.in: Add various Make variables that the various
1541 * std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC
1542 and optimizing by default.
1544 Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au>
1546 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
1547 make them functions again. Appears 2.6.3 is confused by just a
1550 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
1552 * ppc-endian.c (SWAP_8): Fix 8 byte swap!
1554 * psim.c (psim_create): Not correctly checking that runtime
1555 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
1556 matched the compiled in ones.
1558 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
1559 trace_semantics is now different to trace_idecode, the former
1562 Tue Oct 24 21:54:13 1995 Andrew Cagney <cagney@highland.com.au>
1564 * ppc-instructions (mtsrin): Missing instruction
1565 * ppc-instructions (mfsrin): Missing instruction
1566 * ppc-instructions (eieio): Missing instruction
1568 Tue Oct 24 20:55:29 1995 Andrew Cagney <cagney@highland.com.au>

1575 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
1576 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
1577 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
1578 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
1579 the instruction or data critical paths.
1581 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
1582 the inclusion of device_tree.c/emul_generic.c.
1584 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
1586 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace

1597 undefined when restarting from within gdb.
1599 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
1600 instruction cache (if present). Fixes problem of cpu caching gdb
1601 breakpoint instructions.
1603 FIXME: PSIM sometimes aborts calling error(), it should instead
1604 call sim_error() say which takes care of housekeeping such as
1605 saving the CIA before calling error.
1607 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
1608 used when restarting a simulation because the latter has the
1609 unwanted side effect (well I as a kernel hacker think it is) of
1610 performing an isync when the instruction stream doesn't contain
1613 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
1615 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
1616 monitoring module. Counts both instructions issued and
1619 * NOTE: mon does not contain to count instruction loads as this
1620 information is already available from the mon_issue() hook.
1622 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
1624 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
1625 a common monitor to each of the cpus. Delete
1626 cpu_increment_number_of_insns() and cpu_get_number_of_insns()

1631 * sim_calls.c, main.c, psim.c (psim_create): always create
1632 `WITH_SMP' cpus. The actual number of CPU's active in a
1633 simulation run is taken from the device node: /init/smp (an
1634 integer). WITH_SMP changed to 2 (remember to put it back to 0).
1636 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
1638 * system.c: More system call emulation. If code appears NetBSD

1644 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
1645 lf.[ch](new), table.[ch](new): Split into two generators - igen
1646 that outputs the instruction tables and dgen that outputs the spr
1647 tables. Add -f (filter out) flag to igen to filter out certain
1648 instructions (ex 64 bit ones) from the created tables. Include
1649 $(LIBIBERTY_LIB) in link options in case host lacks some libc
1652 * NOTE: igen, since it was originally written for the
1653 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.

1661 an table of all the instructions. Code to output a type
1662 enumerating all the instructin names.
1664 * igen.c(lf_print_c_semantic): Move call to increment instruction
1665 counter so that it occures _after_ the instruction has been fully
1666 validated, was double counting illegal/invalid instructions. Add
1667 conditional so only compiled in when WITH_PROFILE enabled (enabled
1670 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
1671 itable.h, count individual instruction types not just total,

1727 * Makefile.in (clean): Delete *.i and *.out files.
1729 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
1730 macros for either assignment or return. Fix SWAP_8 to use a
1731 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
1732 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
1733 that hardwired swapping on/off, let optimizer delete dead code.
1735 * main.c (main): Add printf that we caught a signal and print out

1756 cracking instruction cache. Delete the code that cached just the
1757 result from doing an instruction lookup - this ran slower than no
1760 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1762 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).

1779 (cpu_print_info): Use it to print number_of_insns.
1781 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
1783 (ENDIAN_N): If both target and host byte orders are known, don't
1784 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
1786 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
1787 to allow target specific H2T_n/T2H_n macros to be used.
1788 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
1789 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
1790 of the 3 instruction sequence that runs on 386s.
1792 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
1793 specified on the compile line.
1794 (WITH_BSWAP): If not defined, define as 0.

1797 default inline support. Pass INLINE_CFLAGS when compiling.
1799 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
1800 INLINE_DEVICES since GCC doesn't like inline functions that
1801 accept variable arguments.

1803 doesn't like inline functions that accept variable arguments.
1805 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1807 * inline.c: Correct pathnames of included C files to match current
1810 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1811 non-zero, define STATIC_DEVICES to be static.
1813 * std-config.h (INLINE): If GNU C and optimizing, define this as
1815 (DEFAULT_INLINE): If not defined, define as 0.
1816 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1817 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.

1822 * ppc-instructions: Initial cut of floating point suport added.
1823 Of note include - use of host IEEE floating point instructions,
1824 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1825 currently a pretty sight.
1827 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1828 merge into core.h, core.c, core_n.h. The type memory_map replaced
1829 with core_map. This removes a level of pointer indirection when
1830 translating an address.
1832 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1834 * Makefile.in et.al (sorry): tweek to use new core, core_map and

1848 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
1850 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1851 callback interface so that there is a read/write buffer but no
1852 read/write_word. VEA default memory read/write handler sometimes
1853 couldn't resolve an access and of those some were for a memory
1854 fault and some were because gdb was making a bogus request.
1856 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
1857 eliminate transfer_mode (raw or cooked) parameter from read/write

1872 handled by a device. Arguments passed across using a device ioctl
1875 * devices.h, devices.c: device ioctl callback changed to allow a
1876 variable number of arguments. This gives greater flexability and
1877 greater chance of bugs.
1879 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
1881 * main.c (printf_filtered, error): Missing va_end() to close off
1882 variable argument use.
1884 * Makefile.in (tmp-gencode): comment out hack to get around some
1885 versions of make not handling files being created as side-effects.
1887 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
1888 alternative file name to use in output files for things like #line
1891 Makefile.in (tmp-gencode): Use gen -n so that debug info is
1894 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the

1914 At present, print the number of instructions executed.
1916 * gen_idecode_c: Emit call to cpu_increment_number_of_insns within
1919 * psim.c (psim_print_info): New function to iterate over each of
1920 the CPU's calling cpu_print_info.
1922 * psim.h,cpu.h: Add new declarations.
1924 * sim_calls.c (sim_open): Add argument processing to add the same
1925 switches main.c accepts for the standalone processor.
1926 (sim_close): Call psim_print_info if -I.
1928 * main.c (main): Add comment saying to update sim_calls.c when
1929 adding switches. Add -I to call psim_print_info when done.
