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

741 defined in lf_print_c_extraction.
742 (main): Recognize -R.

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

867 * Makefile.in: Ditto.
869 * function_unit.{c,h}: Delete these now usused files.

877 for WITH_MODEL_ISSUE.
878 * mon.c (mon_issue): Remove call to mon_issue_here.
880 * ppc-instructions: Move branch tracing to the actual branch
881 instructions, rather than testing it in model_issue. Add code to
882 code successful/unsuccessful branch predictions, and the number of
883 conditional branches that fell through.
885 Wed Nov 15 17:32:13 1995 Michael Meissner <meissner@tiktok.cygnus.com>
887 * cpu.h (cpu_model): Add declaration.

955 Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
957 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
958 inline.. Only problem being that with ppc-opcode-simple this gave
959 it the chance to inline all the idecode functions with potentially
960 disasterous results on a 16mb PC. For moment hobble INLINE.
962 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
965 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
966 Firstly make them errors and secondly remove the options gcc-245
969 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
971 * misc.c (zalloc), cpu.c (cpu_init), devices
972 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
973 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
974 sim_calls.c (zalloc) : replace bzero() with memset().
976 * emul_netbsd.c (write_direntries), psim.c (psim_read_register,
977 psim_write_register): replace bcopy() with memcpy().
979 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
981 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
982 force DEFAULT_INLINE to 0 rather then trusting the std
985 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
987 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
988 generation of switch entries in tables - treat the same as
989 cracking/semantic functions.
991 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
992 of a boolean switch statement (field zero or non-zero).
994 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
995 switch/table generation ability of igen.
997 * igen.c (idecode_switch_leaf): Fix code output when a switch
998 statement needs to look up a table.
1000 * igen.c (idecode_declare_if_switch): New function called from
1001 gen_idecode_c - need to declare any idecode switch functions
1002 before they are used in idecode tables.
1004 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
1005 idecode_crack_insn): Add is_inline_function argument to code
1006 printing cracker functions which indicates if STATIC_IDECODE or
1007 STATIC_INLINE_IDECODE should be used for definition. For
1008 idecode_crack_insn (which implies not duplicating/expanding) don't
1009 declare function as inline - we assume that the only time this is
1010 code is generated is when things are being tested. For
1011 idecode_crack_leaf, make static (instead of INLINE) if the
1012 instructions parent is a table as function will always be called
1015 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
1016 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
1017 called directly, all others are called via a table.
1019 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
1020 semantics_h_insn, semantics_h_function,
1021 lf_print_c_semantic_function, semantics_c_function): Add
1022 is_inline_function argument to lf_print_semantic_function_header
1023 to indicate if an inline or static function declaration/definition
1024 should be output. Depending on situtation call accordingly:
1025 functions (not instruction semantic routines) are always inline;
1026 Semantic routines are made inline when there is no icache (cache
1027 will contain the function address) and are duplicating (see above)
1028 and the parent of the instruction is a switch statement.
1030 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
1031 and moved to insn_table_find_opcode_field.
1033 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
1035 * igen.c (model_c_insn): Suggestion - document the name of the
1036 instruction on each line of the instruction model table.
1038 Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au>
1040 * emul_netbsd.c (do_ioctl): Cleanup compilation.
1042 * sim_callbacks.h (__attribute__): Only define if not defined (was
1043 already defined on NetBSD host).

1047 * std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New
1048 macro, indicates if the PowerPC's horrible XOR endian mode should
1049 be suported. Add to configure and make.
1051 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
1052 (vm_instruction_map_read): If XOR endian, xor the address
1053 with a value from an xor table (indexed by size of access).
1055 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
1056 set up xor table to xor if there is a conflict between the
1057 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
1058 check of suported change of endian mode from cpu.c to vm.c.
1060 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
1061 Hopefully added correct hack to handle XOR endian mode.
1063 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
1064 little endian mode, the model accepts miss aligned transfers.
1066 FIXME: Need to create an `init' device that, during
1067 initializatioin for XOR mode, it mushes (XOR address) all the dma
1068 data before passing it on to the core for storage. Just like the
1071 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
1073 * devices.c (halt_io_write_buffer_callback): Use value written to
1074 halt device to determine exit status. Thus allowing
1075 success/failure of OEA tests.
1077 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>
1079 * ppc-instructions (icbi): If icache present flush it.
1081 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
1083 * devices.c (htab_init_callback): Add code to create htab/pte.
1085 * devices.c (dma_file, file_init_callback, htab_init_callback):
1086 New function - Dma the named file into memory at the specified
1089 * device_tree.h, device_tree.c (scand_*): New functions.
1091 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
1093 * filter_filename.c, Makefile.in: Change so that only dependant on
1094 a very limited nr of files. Stops an unnecessary dependency.
1096 Tue Nov 7 15:44:33 1995 Andrew Cagney <cagney@highland.com.au>
1098 * core.c (core_map_find_mapping): Use cpu_halt rather than error
1099 to abort an access to an undefined address.

1111 * ppc-instructions (model_{start,halt,print_info}): Add dummy
1114 * options.c (print_options): Print out WITH_{,DEFAULT_}MODEL, not
1115 WITH_PPC_{,DEFAULT_}_MODEL.

1661 * psim.c (psim_create): Not correctly checking that runtime
1662 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
1663 matched the compiled in ones.
1665 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
1666 trace_semantics is now different to trace_idecode, the former
1669 Tue Oct 24 21:54:13 1995 Andrew Cagney <cagney@highland.com.au>
1671 * ppc-instructions (mtsrin): Missing instruction
1672 * ppc-instructions (mfsrin): Missing instruction
1673 * ppc-instructions (eieio): Missing instruction
1675 Tue Oct 24 20:55:29 1995 Andrew Cagney <cagney@highland.com.au>
1677 * build-psim: New shell script - see internals for usage,
1678 simplifies the process of building custom simulators.
1680 Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney@highland.com.au>
1682 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
1683 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
1684 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
1685 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
1686 the instruction or data critical paths.
1688 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
1689 the inclusion of device_tree.c/emul_generic.c.
1691 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
1693 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace
1694 system.[hc]. Start of suport for multiple emulations and
1695 emulation state (os_emul object).
1697 * emul_generic.[hc]: Start of code to implement proper system call
1700 Sun Oct 22 21:33:51 1995 Andrew Cagney <cagney@highland.com.au>
1702 * cpu.h, cpu.c (cpu_init): New function, zero the registers before
1703 the processor is started. Fixes problem of registers being
1704 undefined when restarting from within gdb.
1706 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
1707 instruction cache (if present). Fixes problem of cpu caching gdb
1708 breakpoint instructions.
1710 FIXME: PSIM sometimes aborts calling error(), it should instead
1711 call sim_error() say which takes care of housekeeping such as
1712 saving the CIA before calling error.
1714 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
1715 used when restarting a simulation because the latter has the
1716 unwanted side effect (well I as a kernel hacker think it is) of
1717 performing an isync when the instruction stream doesn't contain
1720 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
1722 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
1723 monitoring module. Counts both instructions issued and
1726 * NOTE: mon does not contain to count instruction loads as this
1727 information is already available from the mon_issue() hook.
1729 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
1731 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
1732 a common monitor to each of the cpus. Delete
1733 cpu_increment_number_of_insns() and cpu_get_number_of_insns()
1734 replaced by copied code in mon.[hc].
1736 Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au>
1738 * sim_calls.c, main.c, psim.c (psim_create): always create
1739 `WITH_SMP' cpus. The actual number of CPU's active in a
1740 simulation run is taken from the device node: /init/smp (an
1741 integer). WITH_SMP changed to 2 (remember to put it back to 0).
1743 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
1745 * system.c: More system call emulation. If code appears NetBSD
1746 specific, make conditional to being compiled on a NetBSD system
1749 Wed Oct 18 23:02:20 1995 Andrew Cagney <cagney@highland.com.au>
1751 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
1752 lf.[ch](new), table.[ch](new): Split into two generators - igen
1753 that outputs the instruction tables and dgen that outputs the spr
1754 tables. Add -f (filter out) flag to igen to filter out certain
1755 instructions (ex 64 bit ones) from the created tables. Include
1756 $(LIBIBERTY_LIB) in link options in case host lacks some libc
1759 * NOTE: igen, since it was originally written for the
1760 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
1762 * Makefile.in, std-config.h, ppc-cache-rules(new),
1763 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
1764 cache-rule and opcode-rule tables from macros found std-config.h.
1765 Delete corresponding macro's from std-config.h.
1767 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
1768 an table of all the instructions. Code to output a type
1769 enumerating all the instructin names.
1771 * igen.c(lf_print_c_semantic): Move call to increment instruction
1772 counter so that it occures _after_ the instruction has been fully
1773 validated, was double counting illegal/invalid instructions. Add
1774 conditional so only compiled in when WITH_PROFILE enabled (enabled
1777 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
1778 itable.h, count individual instruction types not just total,
1779 adjust reporting functions to output this.
1781 * ppc-instructions (64 bit Load Doubleword with Update Indexed):
1782 Had 32./ instead of 31./
1784 * ppc-instructions (64 bit Store Double Word Conditional Indexed):
1785 bitrot - updated to use newer CR register operators.
1787 * ppc-instructions (64bit Floating Convert from Integer
1788 Doubleword): Correct call to Round_Float().
1790 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
1792 * basics.h: #include "sim_callbacks.h" earlier so that its
1793 prototypes are declared in all other header files.
1795 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
1796 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
1799 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
1800 Add size of buffer argument to functions writing a string into a
1801 buffer. Check for buffer overflow.
1803 Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au>
1805 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing
1806 of each device. Make parameter names consistent so macros work.
1807 Use macro's in device functions.
1809 * device_tree.c, devices.h, devices.c: include path to device in a
1810 devices node when creating it.
1812 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.
1814 * core.c: add tracing of core-device, adjust parameter names in
1815 core functions to be consistent with those in devices*.
1817 Sun Oct 15 20:33:20 1995 Andrew Cagney <cagney@highland.com.au>
1819 * debug.h, debug.c (trace_option): New function. Parses the trace
1820 option, updating the trace array.
1822 * debug.h, debug.c (trace_usage): New function. Outputs the list
1823 of all possible trace options.
1825 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
1826 parse trace options specified with the simpler -t flag. Adjust
1829 * FIXME: basic parsing of command line options is still duplicated
1830 by main.c and sim_calls.c
1832 Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1834 * Makefile.in (clean): Delete *.i and *.out files.
1836 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
1837 macros for either assignment or return. Fix SWAP_8 to use a
1838 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
1839 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
1840 that hardwired swapping on/off, let optimizer delete dead code.
1842 * main.c (main): Add printf that we caught a signal and print out
1843 the failing address.
1845 Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>
1847 * Makefile.in: Remove tabs from otherwise empty line.

1857 instructions here so it works with caching.
1858 (gen_idecode_c): Move from here.
1860 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1862 * gen.c, ppc-instructions, psim.c: Fix code for generating
1863 cracking instruction cache. Delete the code that cached just the
1864 result from doing an instruction lookup - this ran slower than no
1867 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1869 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
1871 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
1872 TCL when gdb is linked with the simulator.
1873 * debug.c (ppc_trace): Ditto.
1874 * sim_calls.c (sim_open): Change trace -> ppc_trace.

1882 psim.o depend on all sources.
1884 * cpu.c (cpu_add_commas): New function to format a long with
1886 (cpu_print_info): Use it to print number_of_insns.
1888 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
1890 (ENDIAN_N): If both target and host byte orders are known, don't
1891 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
1893 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
1894 to allow target specific H2T_n/T2H_n macros to be used.
1895 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
1896 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
1897 of the 3 instruction sequence that runs on 386s.
1899 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
1900 specified on the compile line.
1901 (WITH_BSWAP): If not defined, define as 0.
1903 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
1904 default inline support. Pass INLINE_CFLAGS when compiling.
1906 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
1907 INLINE_DEVICES since GCC doesn't like inline functions that
1908 accept variable arguments.
1909 (stack_ioctl_callback): Make function just static because GCC
1910 doesn't like inline functions that accept variable arguments.
1912 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1914 * inline.c: Correct pathnames of included C files to match current
1917 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1918 non-zero, define STATIC_DEVICES to be static.
1920 * std-config.h (INLINE): If GNU C and optimizing, define this as
1922 (DEFAULT_INLINE): If not defined, define as 0.
1923 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1924 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
1925 ({SPREG,IDECODE}_INLINE): Ditto.
1927 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1929 * ppc-instructions: Initial cut of floating point suport added.
1930 Of note include - use of host IEEE floating point instructions,
1931 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1932 currently a pretty sight.
1934 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1935 merge into core.h, core.c, core_n.h. The type memory_map replaced
1936 with core_map. This removes a level of pointer indirection when
1937 translating an address.
1939 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1941 * Makefile.in et.al (sorry): tweek to use new core, core_map and

1947 most of the other functions in sim_calls.c.
1949 * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
1950 Add macros to better cover up `generic' code. Makes it possible
1951 to step through the generic code!
1953 * vm.c, vm_n.h, Makefile.in: ditto
1955 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
1957 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1958 callback interface so that there is a read/write buffer but no
1959 read/write_word. VEA default memory read/write handler sometimes
1960 couldn't resolve an access and of those some were for a memory
1961 fault and some were because gdb was making a bogus request.
1963 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
1964 eliminate transfer_mode (raw or cooked) parameter from read/write
1967 Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>
1969 * ppc-instructions (fmul, fmuls): correct instruction format - had
1972 Wed Oct 4 17:31:12 1995 Andrew Cagney <cagney@highland.com.au>

1975 scand_*): new functions to parse/print fields in device names
1976 while hiding any machine dependency.
1978 * devices.c, psim.c: Change the stack init code so that it is
1979 handled by a device. Arguments passed across using a device ioctl
1982 * devices.h, devices.c: device ioctl callback changed to allow a
1983 variable number of arguments. This gives greater flexability and
1984 greater chance of bugs.
1986 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
1988 * main.c (printf_filtered, error): Missing va_end() to close off
1989 variable argument use.
1991 * Makefile.in (tmp-gencode): comment out hack to get around some
1992 versions of make not handling files being created as side-effects.
1994 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
1995 alternative file name to use in output files for things like #line
1998 Makefile.in (tmp-gencode): Use gen -n so that debug info is
2001 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the

2021 At present, print the number of instructions executed.
2023 * gen_idecode_c: Emit call to cpu_increment_number_of_insns within
2026 * psim.c (psim_print_info): New function to iterate over each of
2027 the CPU's calling cpu_print_info.
2029 * psim.h,cpu.h: Add new declarations.
2031 * sim_calls.c (sim_open): Add argument processing to add the same
2032 switches main.c accepts for the standalone processor.
2033 (sim_close): Call psim_print_info if -I.
2035 * main.c (main): Add comment saying to update sim_calls.c when
2036 adding switches. Add -I to call psim_print_info when done.

2062 * device_tree.c (create_option_device_node): Assume a program is
2063 OEA if the start address is < 4096, not just == 0.

2112 wrong address (0) instead of &end.
2114 * core.c (core_add_stack, core_add_data): Was not handling case
2115 where bss/stack is grown across the current end-of-{bss,stack}.
2117 Wed Sep 6 00:46:10 1995 Andrew Cagney <cagney@highland.com.au>
2119 * system.c (system_call): Fix SYS_break - was aligning bss to a
2120 page boundary instead of just an 8 byte one; On first call sbrk(0)

2140 and make tracing output line up.
2142 * Makefile.in: Rewrite from Makefile to work with the Cygnus
2143 environment, and support compiling in a different directory than
2144 the sources reside in.
2146 * ppc-endian.h: Rename from endian.h so that it doesn't get
2147 confused with /usr/include/sys/endian.h on Linux. Add Linux
2150 * ppc-endian.c: Rename to be consistant with ppc-endian.h.
2151 Include ppc-endian.h, not endian.h.

2183 * device_tree.c (create_option_device_node): Alignment rules (at
2184 least for the moment) now are for strict alignment only for LE OEA
2185 mode. (Because of compiler problems).
2187 * system.c (system_call) SYS_exit: Wasn't exiting with correct status.
2189 Thu Aug 17 01:16:38 1995 Andrew Cagney <cagney@highland.com.au>
2191 * vm.c (DEFINE_VM_DATA_MAP_WRITE_N): For miss aligned transfer
2194 * system.c (system_call): didn't page align break argument before
2195 determining increment break increment.
2197 * psim/ppc: Re-arange entire directory structure so that
2198 everything lives in the one directory. While a pain for cleaning,
2199 makes building across multiple architectures much simpler.
2201 * devices.c, device_tree.c: Added code that provides a simple
2202 illustration of how an interrupt control device could be
2205 * devices.c: Added code so that the dumb console device can read
2206 (from stdin) as well as write to stdout.
