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

710 * mon.c (mon_issue): Remove call to mon_issue_here.
712 * ppc-instructions: Move branch tracing to the actual branch
713 instructions, rather than testing it in model_issue. Add code to
714 code successful/unsuccessful branch predictions, and the number of
715 conditional branches that fell through.
717 Wed Nov 15 17:32:13 1995 Michael Meissner <meissner@tiktok.cygnus.com>

787 Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
789 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
790 inline.. Only problem being that with ppc-opcode-simple this gave
791 it the chance to inline all the idecode functions with potentially
792 disasterous results on a 16mb PC. For moment hobble INLINE.
794 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
797 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
798 Firstly make them errors and secondly remove the options gcc-245
801 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
803 * misc.c (zalloc), cpu.c (cpu_init), devices
804 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
805 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
806 sim_calls.c (zalloc) : replace bzero() with memset().
808 * emul_netbsd.c (write_direntries), psim.c (psim_read_register,
809 psim_write_register): replace bcopy() with memcpy().
811 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
813 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
814 force DEFAULT_INLINE to 0 rather then trusting the std
817 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
819 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
820 generation of switch entries in tables - treat the same as
821 cracking/semantic functions.
823 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
824 of a boolean switch statement (field zero or non-zero).
826 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
827 switch/table generation ability of igen.
829 * igen.c (idecode_switch_leaf): Fix code output when a switch
830 statement needs to look up a table.
832 * igen.c (idecode_declare_if_switch): New function called from
833 gen_idecode_c - need to declare any idecode switch functions
834 before they are used in idecode tables.
836 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
837 idecode_crack_insn): Add is_inline_function argument to code
838 printing cracker functions which indicates if STATIC_IDECODE or
839 STATIC_INLINE_IDECODE should be used for definition. For
840 idecode_crack_insn (which implies not duplicating/expanding) don't
841 declare function as inline - we assume that the only time this is
842 code is generated is when things are being tested. For
843 idecode_crack_leaf, make static (instead of INLINE) if the
844 instructions parent is a table as function will always be called
847 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
848 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
849 called directly, all others are called via a table.
851 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
852 semantics_h_insn, semantics_h_function,
853 lf_print_c_semantic_function, semantics_c_function): Add
854 is_inline_function argument to lf_print_semantic_function_header
855 to indicate if an inline or static function declaration/definition
856 should be output. Depending on situtation call accordingly:
857 functions (not instruction semantic routines) are always inline;
858 Semantic routines are made inline when there is no icache (cache
859 will contain the function address) and are duplicating (see above)
860 and the parent of the instruction is a switch statement.
862 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
863 and moved to insn_table_find_opcode_field.
865 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
867 * igen.c (model_c_insn): Suggestion - document the name of the
868 instruction on each line of the instruction model table.
870 Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au>
872 * emul_netbsd.c (do_ioctl): Cleanup compilation.
874 * sim_callbacks.h (__attribute__): Only define if not defined (was
875 already defined on NetBSD host).
877 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>

880 macro, indicates if the PowerPC's horrible XOR endian mode should
881 be suported. Add to configure and make.
883 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
884 (vm_instruction_map_read): If XOR endian, xor the address
885 with a value from an xor table (indexed by size of access).
887 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
888 set up xor table to xor if there is a conflict between the
889 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
890 check of suported change of endian mode from cpu.c to vm.c.
892 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
893 Hopefully added correct hack to handle XOR endian mode.
895 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
896 little endian mode, the model accepts miss aligned transfers.
898 FIXME: Need to create an `init' device that, during
899 initializatioin for XOR mode, it mushes (XOR address) all the dma
900 data before passing it on to the core for storage. Just like the
903 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
905 * devices.c (halt_io_write_buffer_callback): Use value written to
906 halt device to determine exit status. Thus allowing
907 success/failure of OEA tests.
909 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>
911 * ppc-instructions (icbi): If icache present flush it.
913 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
915 * devices.c (htab_init_callback): Add code to create htab/pte.
917 * devices.c (dma_file, file_init_callback, htab_init_callback):
918 New function - Dma the named file into memory at the specified

923 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
925 * filter_filename.c, Makefile.in: Change so that only dependant on
926 a very limited nr of files. Stops an unnecessary dependency.
928 Tue Nov 7 15:44:33 1995 Andrew Cagney <cagney@highland.com.au>
930 * core.c (core_map_find_mapping): Use cpu_halt rather than error
931 to abort an access to an undefined address.

963 name for the model, not the internal identifier used.
965 * psim.c (current_model): New global variable.

972 * sim_calls.c, Makefile.in: sim_calls.c now includes cpu.h.

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

1330 * Makefile.in: Uncomment built file dependencies.
1332 * configure.in: Rewrite --enable-sim switch handling to use the

1368 of reads and writes. If getrusage is supported, print out number
1369 of simulated instructins per second.
1371 * configure.in: Add support for --enable-sim-opcode=stupid.

1412 Tue Oct 31 21:31:32 1995 Andrew Cagney <cagney@highland.com.au>
1414 * ppc-opcode-stupid: Third example of use of opcode table - this
1415 one expands all mtspr/mfspr and branch instructions. Appears to
1416 give about a 10% gain in performance if everything enabled. Also
1417 takes about 150mb of swap to build.

1480 * std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC
1481 and optimizing by default.
1483 Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au>
1485 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
1486 make them functions again. Appears 2.6.3 is confused by just a
1489 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
1491 * ppc-endian.c (SWAP_8): Fix 8 byte swap!

1503 * ppc-instructions (mtsrin): Missing instruction
1504 * ppc-instructions (mfsrin): Missing instruction

1514 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
1515 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
1516 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
1517 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
1518 the instruction or data critical paths.
1520 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
1521 the inclusion of device_tree.c/emul_generic.c.

1539 instruction cache (if present). Fixes problem of cpu caching gdb
1540 breakpoint instructions.
1542 FIXME: PSIM sometimes aborts calling error(), it should instead
1543 call sim_error() say which takes care of housekeeping such as
1544 saving the CIA before calling error.
1546 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
1547 used when restarting a simulation because the latter has the
1548 unwanted side effect (well I as a kernel hacker think it is) of
1549 performing an isync when the instruction stream doesn't contain
1552 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
1554 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
1555 monitoring module. Counts both instructions issued and

1570 * sim_calls.c, main.c, psim.c (psim_create): always create
1571 `WITH_SMP' cpus. The actual number of CPU's active in a

1573 integer). WITH_SMP changed to 2 (remember to put it back to 0).
1575 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
1577 * system.c: More system call emulation. If code appears NetBSD

1588 $(LIBIBERTY_LIB) in link options in case host lacks some libc
1591 * NOTE: igen, since it was originally written for the
1592 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
1594 * Makefile.in, std-config.h, ppc-cache-rules(new),
1595 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
1596 cache-rule and opcode-rule tables from macros found std-config.h.

1603 * igen.c(lf_print_c_semantic): Move call to increment instruction
1604 counter so that it occures _after_ the instruction has been fully
1605 validated, was double counting illegal/invalid instructions. Add
1606 conditional so only compiled in when WITH_PROFILE enabled (enabled
1609 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
1610 itable.h, count individual instruction types not just total,

1624 * basics.h: #include "sim_callbacks.h" earlier so that its
1625 prototypes are declared in all other header files.
1627 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
1628 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into

1657 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
1658 parse trace options specified with the simpler -t flag. Adjust
1661 * FIXME: basic parsing of command line options is still duplicated
1662 by main.c and sim_calls.c
1664 Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1666 * Makefile.in (clean): Delete *.i and *.out files.
1668 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
1669 macros for either assignment or return. Fix SWAP_8 to use a
1670 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
1671 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
1672 that hardwired swapping on/off, let optimizer delete dead code.
1674 * main.c (main): Add printf that we caught a signal and print out
1675 the failing address.
1677 Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>
1679 * Makefile.in: Remove tabs from otherwise empty line.

1692 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1694 * gen.c, ppc-instructions, psim.c: Fix code for generating
1695 cracking instruction cache. Delete the code that cached just the
1696 result from doing an instruction lookup - this ran slower than no
1699 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1701 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
1703 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
1704 TCL when gdb is linked with the simulator.
1705 * debug.c (ppc_trace): Ditto.
1706 * sim_calls.c (sim_open): Change trace -> ppc_trace.

1714 psim.o depend on all sources.
1716 * cpu.c (cpu_add_commas): New function to format a long with
1718 (cpu_print_info): Use it to print number_of_insns.
1720 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
1722 (ENDIAN_N): If both target and host byte orders are known, don't
1723 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
1725 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
1726 to allow target specific H2T_n/T2H_n macros to be used.
1727 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
1728 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
1729 of the 3 instruction sequence that runs on 386s.
1731 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
1732 specified on the compile line.
1733 (WITH_BSWAP): If not defined, define as 0.
1735 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
1736 default inline support. Pass INLINE_CFLAGS when compiling.
1738 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
1739 INLINE_DEVICES since GCC doesn't like inline functions that
1740 accept variable arguments.
1741 (stack_ioctl_callback): Make function just static because GCC
1742 doesn't like inline functions that accept variable arguments.
1744 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1746 * inline.c: Correct pathnames of included C files to match current
1749 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1750 non-zero, define STATIC_DEVICES to be static.
1752 * std-config.h (INLINE): If GNU C and optimizing, define this as
1754 (DEFAULT_INLINE): If not defined, define as 0.
1755 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1756 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
1757 ({SPREG,IDECODE}_INLINE): Ditto.
1759 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1761 * ppc-instructions: Initial cut of floating point suport added.
1762 Of note include - use of host IEEE floating point instructions,
1763 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1764 currently a pretty sight.
1766 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1767 merge into core.h, core.c, core_n.h. The type memory_map replaced
1768 with core_map. This removes a level of pointer indirection when
1769 translating an address.
1771 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1773 * Makefile.in et.al (sorry): tweek to use new core, core_map and

1782 Add macros to better cover up `generic' code. Makes it possible
1783 to step through the generic code!
1785 * vm.c, vm_n.h, Makefile.in: ditto
1787 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
1789 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1790 callback interface so that there is a read/write buffer but no
1791 read/write_word. VEA default memory read/write handler sometimes
1792 couldn't resolve an access and of those some were for a memory
1793 fault and some were because gdb was making a bogus request.
1795 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
1796 eliminate transfer_mode (raw or cooked) parameter from read/write
1799 Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>
1801 * ppc-instructions (fmul, fmuls): correct instruction format - had

1807 scand_*): new functions to parse/print fields in device names
1808 while hiding any machine dependency.
1810 * devices.c, psim.c: Change the stack init code so that it is
1811 handled by a device. Arguments passed across using a device ioctl
1814 * devices.h, devices.c: device ioctl callback changed to allow a
1815 variable number of arguments. This gives greater flexability and
1816 greater chance of bugs.
1818 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
1820 * main.c (printf_filtered, error): Missing va_end() to close off
1821 variable argument use.
1823 * Makefile.in (tmp-gencode): comment out hack to get around some
1824 versions of make not handling files being created as side-effects.
1826 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
1827 alternative file name to use in output files for things like #line
1830 Makefile.in (tmp-gencode): Use gen -n so that debug info is
1833 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the

1853 At present, print the number of instructions executed.
1855 * gen_idecode_c: Emit call to cpu_increment_number_of_insns within
1858 * psim.c (psim_print_info): New function to iterate over each of
1859 the CPU's calling cpu_print_info.
1861 * psim.h,cpu.h: Add new declarations.
1863 * sim_calls.c (sim_open): Add argument processing to add the same
1864 switches main.c accepts for the standalone processor.
1865 (sim_close): Call psim_print_info if -I.
1867 * main.c (main): Add comment saying to update sim_calls.c when
1868 adding switches. Add -I to call psim_print_info when done.

1890 * main.c (main): Switch to using getopt. Make -p also set
1891 trace_semantics. Make -a turn on all trace flags. Make -C turn
1894 * device_tree.c (create_option_device_node): Assume a program is
1895 OEA if the start address is < 4096, not just == 0.
1897 Wed Sep 20 13:36:06 1995 Ian Lance Taylor <ian@cygnus.com>

1941 Wed Sep 6 13:25:42 1995 Andrew Cagney <cagney@highland.com.au>
1943 * core.c (core_add_data): First growth of bss was being put at
1944 wrong address (0) instead of &end.
1946 * core.c (core_add_stack, core_add_data): Was not handling case
1947 where bss/stack is grown across the current end-of-{bss,stack}.
1949 Wed Sep 6 00:46:10 1995 Andrew Cagney <cagney@highland.com.au>
1951 * system.c (system_call): Fix SYS_break - was aligning bss to a
