730 * options.c (options_inline): Function to output meaningful
731 description of the INLINE options.
733 * configure.in (inline): Replace inline magic numbers with macro
734 names. Map 1->LOCALS_INLINE and 2->ALL_INLINE.

753 Tue Dec 5 11:56:14 1995 Andrew Cagney <cagney@sawnoff>
755 * ppc-instructions (ppc_nr_mtcrf_crs, ppc_branch_conditional_name,
756 ppc_function_unit_name): Simplify by declaring these arrays as
757 pure and simple static (instead of STATIC_MODEL).
761 * sim_calls.c (sim_create, sim_load), main.c (main), psim.c: Pass
762 an options device into psim_create() so that options can be merged
765 * device.c (*add*): Change semantics so the add functions only add
766 when the new device (or property) doesn't already exist. This
767 allows merging of options and data.
769 Mon Dec 4 17:12:13 1995 Andrew Cagney <cagney@sawnoff>
771 * Makefile.in (BASICS_H): Didn't include basics.h in the list of
772 header files to depend on.
774 Mon Dec 4 17:12:13 1995 Andrew Cagney <cagney@sawnoff>
776 * std-config.h: (*_MODULE): Extend the <module>_inline macro's so
777 that they also allow control over static functions. Rewrite
778 document to reflect this.
780 * std-config.h: (INLINE): Simplify definition, the above and
781 earlier changes to igen.h eliminate the need to be defensive about
782 enabling the inline of static functions.
784 * std-config.h: (SIM_ENDIAN_INLINE, BITS_INLINE): Document limited
785 suport for inlineing of modules for all callers. Adjust relevant
786 macro's so that DEFAULT_INLINE will enable this.
788 * basics.h: Re-order #includes and definitions so that c-code for
789 basic include files does not call functions delcared in later
792 * basics.h (__attribute__), sim_callbacks.h: Move attribute macro
793 to basics.h and add hack (include <stdio.h>) to try and bring that
794 and other possible conflicting macros into scope much earler.
796 * sim-endian.h,c (SIM_ENDIAN_INLINE) bits.h,c (BITS_INLINE):
797 Change to use the updated inline definitions. If enabled
798 immediatly include the corresponding c-code so that it will inline
801 * inline.h, inline.c (SIM_ENDIAN_INLINE, BITS_INLINE): Remove
802 these cases, moved to module specific header files.
806 * vm.c, vm_n.c: Fix htab code.
808 * vm.c (vm_data_map_read_buffer): Was using EA not RA when reading
811 * device.c: Fix htab create code.
815 * bits.h, bits.c (EXTRACTED): Convert to function, fix - had &&
818 * sim-endian.h (SWAP_N), sim-endian-n.h, sim-endian.c: How
819 embarasing - fix yet another bug in the swap code! Simplify
820 everything by using more functions. Add host to big-endian byte
825 * devices.h, devices.c: delete, replaced by the files
826 device_table.[ch] and device.[ch].
827 * device_tree.h, device_tree.c: ditto

840 * psim.c (create_*_tree): Use new device_tree create functions.
842 * corefile.h, corefile.c corefile-n.h (core_n.h): Update to use
843 the new device.h / device_table.h interface. Rename core_n.h to
844 corefile-n.h to be consistent with other n files.
846 * Makefile.in (run): add corefile-n.h to dependencies for
849 * basics.h (device_instance), device.h, device.c, device_table.h,
850 device_table.c: Add the concept of a device instance and operators
851 on these instances - corresponds to ihandle in OpenBoot speak.
852 Don't yet implement it.

865 preliminary hooks for a kernel mode rom emulation.
867 * cap.h (new), cap.c (new): Capability data base. Some emulations
868 pass object identifiers (capabilities?) to/from the simulated code
869 (for instance the phandle in OpenBoot). The cap object is able to
870 check/map between internal and external (target program)
871 representations of each identifier.
873 * os_emul.c, emul_chirp.h, emul_chirp.c, Makefile.in: Add

895 and code for spa, no longer to be used.
897 * psim.c (create_chirp_device_tree): Fill out what was previously
898 the openboot create function so that it starts to create a full
899 OpenBoot device tree.

910 initialize the event queue.
919 * sim-endian.h: Look at WORDS_BIGENDIAN to determine if the host

923 * configure{,.in} (--enable-sim-model-issue): Instead of defining
924 0/1, define it to be MODEL_ISSUE_{PROCESS,IGNORE}. Add
925 AC_C_BIGENDIAN to determine if the host is big endian or not.
926 * config.in: Regenerate.
928 * std-config.h (WITH_MODEL_ISSUE): Default to 0.
929 (CURRENT_MODEL_ISSUE): Reference WITH_MODEL_ISSUE, and if that is

958 * configure: Regenerate.
959 * config.in: Regenerate.
961 * cpu.h (CONST_ATTRIBUTE): Define as __attribute__((__const__)) if
963 (cpu_system): Use CONST_ATTRIBUTE, so that when we're not inlining
964 the world, the optimizer has a fair chance of CSE'ing function
966 (cpu_{monitor,nr,registers,model}): Ditto.
968 * std-config.h (MODEL_INLINE): If not defined, define as 1 if
969 DEFAULT_INLINE is non-zero, 0 otherwise, rather than just the
970 value of DEFAULT_INLINE.
974 * lf.h (__attribute__): If not GCC and at least 2.7.0, define as
976 (lf_printf): Add printf __attribute__, so the compiler will
977 automatically check the format string.
979 * configure{,.in} (--enable-sim-icache): If argument is define,
980 add -R to flags passed to igen.
982 * igen.c (stdlib.h): Include if the system supplies one.
983 (semantics_use_cache_struct): New global for -R flag to say
984 semantics is to use the cache structure directly rather than
985 putting the values into local variables.
986 (first_undef, last_undef): New structures to remember names to
988 (lf_print_c_extraction): If -R and this is semantics, emit names
989 as #defines pointing to the cache structure, rather than loading
990 the values into local variables.
991 (lf_print_c_semantic_function): If -R, #undef all of the names
992 defined in lf_print_c_extraction.
993 (main): Recognize -R.

1019 (lf_print_c_extraction): Ditto.
1020 * idecode_expression.h (FPSCR_BEGIN): Ditto.
1022 * ppc-cache-rules: Define rules for making a bitmask for all
1025 * ppc-instructions: Rewrite model specific functions to use the
1026 bitmask of the register number, instead of using the register
1027 pointer to get the register number, and then making the bitmask.
1031 * ppc-instructions (model_branches): Add conditional argument to
1032 count the number of times each type of conditional branch is used.
1033 (conditional branches): Pass B0 or -1 to model_branches.
1034 (model_mon_info): Print out conditional branch counts.
1035 (model-data): Add support for printing out conditional branch

1042 (lf_print_c_semantic): Remove model_cleanup.
1043 (gen_model_{c,h}): Ditto.
1045 * ppc-instructions: Redo model specific support once again. Add
1046 floating point support to the model specific information. Flesh
1047 out all of the floating mutiply add/subtract instructions. Add
1048 better tracing support to the model specific information.
1052 * ppc-instructions (model data, model_busy): Rather than using a
1053 bit mask for the busy units, just use a char array. Also, only
1054 support 2 function units an insn can use, rather than a loop.
1058 * table.c (table_entry_read): Move setting entry->line_nr to after
1059 the model specific fields so the line numbers for the annex are
1062 * cpu.c (cpu_{create,init,halt}): Check for WITH_MODEL_ISSUE
1063 before calling the model functions.
1065 * debug.c (trace_descriptor): Add trace_model support.
1066 * debug.h (trace_options): Ditto.
1068 * igen.c (gen_icache_h): Create type idecode_cache as void if not
1069 caching instructions.

1072 (lf_print_my_prefix): Initialize a const itable_index with the
1074 (lf_print_c_semantic): Call model_cleanup at the end of the
1075 function to check for instructions that aren't supported yet by
1076 the scheduling code.
1078 * mon.h (count_type): New type for counters.
1079 * mon.c: Use count_type instead of unsigned.
1081 * ppc-instructions: Redo scheduling code once again. Make it all
1082 inline friendly. Instead of having general code emitted by igen,
1083 go the route of having each semantic routine call the appropriate
1088 * table.c (table_entry_read): Allow the annex to have blank lines.
1090 * ppc-instructions: Change lines in model stuff that just have a
1091 tab to just newline. Add 601 support. Document most instructions
1092 in terms of model specific timing information. Drop 'FUNCTION'
1093 from PPC_FUNCTION_UNIT_xxx enums. Change PPC_UNIT_UNKNOWN ->
1094 PPC_UNIT_BAD. Add TRACE(trace_tbd) for all data cache
1095 instruction.s. Signal illegal instruciton if data cache block
1096 invalidate is issued from problem state.
1098 * igen.c (max_model_fields_len): New static to keep track of the
1099 max size for the model specific fields.
1100 (model_c_insn): Use max_model_fields_len to size fields.
1101 (insn_table_insert_insn): Set max_model_fields_len.
1102 (model_table_insert): Ditto.

1108 * mon.c (mon_issue): Pass processor argument to model_issue.
1110 * Makefile.in: Delete all function unit support, since the newer
1111 table driven model support replaces it.
1114 * inline.{c,h}: Ditto.
1115 * std-config.h: Ditto.
1117 * configure{,.in}: Ditto.
1118 * Makefile.in: Ditto.
1120 * function_unit.{c,h}: Delete these now usused files.
1122 * std-config.h (WITH_MODEL_ISSUE): Add new macro on whether to
1123 trace instructions in a model specific manor.
1124 * options.c (print_options): Print it out.
1125 * configure{,.in}: Add --enable-sim-model-issue option.
1126 * Makefile.in: Add --enable-sim-model-issue flags.
1127 * igen.c (lf_print_c_semantic): Add call to mon_issue here. Check
1128 for WITH_MODEL_ISSUE.
1129 * mon.c (mon_issue): Remove call to mon_issue_here.
1131 * ppc-instructions: Move branch tracing to the actual branch
1132 instructions, rather than testing it in model_issue. Add code to
1133 code successful/unsuccessful branch predictions, and the number of
1134 conditional branches that fell through.
1138 * cpu.h (cpu_model): Add declaration.
1140 * cpu.c (struct _cpu): Add model_ptr to hold model specific
1142 (cpu_model): Return the model internal pointer.

1166 * igen.c (gen_model_h): Use correct variable in loop.
1167 (gen_model_c): Use strcmp, strcasecmp.

1180 (model support): Move model support around, add support for
1181 model-data, model-internal. Use annex field for model-macros

1185 also define INLINE as nothing.
1186 * configure: Regenerate.
1188 * std-config.h (INLINE): Rather than nuking INLINE, only define it
1189 as __inline__ if any of the INLINE flags are non-zero.

1193 Mon Nov 13 23:03:45 1995 Andrew Cagney <cagneyhighland.com.au>
1195 * ppc-instructions (rfi): Add missing code.
1197 * cpu.c (cpu_get_time_base): Fix calculation of current value of
1200 * ppc-spr-table (TBL, TBU): Fix TBL/TBU entries - was confusing
1201 m[tf]tb with m[tf]spr.
1203 * ppc-instructions (mtspr, mfspr): Fix mttbl - wasn't storing
1206 Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
1208 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
1209 inline.. Only problem being that with ppc-opcode-simple this gave
1210 it the chance to inline all the idecode functions with potentially
1211 disasterous results on a 16mb PC. For moment hobble INLINE.
1213 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
1216 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
1217 Firstly make them errors and secondly remove the options gcc-245
1222 * misc.c (zalloc), cpu.c (cpu_init), devices
1223 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
1224 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
1225 sim_calls.c (zalloc) : replace bzero() with memset().
1227 * emul_netbsd.c (write_direntries), psim.c (psim_read_register,
1228 psim_write_register): replace bcopy() with memcpy().
1230 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
1232 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
1233 force DEFAULT_INLINE to 0 rather then trusting the std
1236 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
1238 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
1239 generation of switch entries in tables - treat the same as
1240 cracking/semantic functions.
1242 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
1243 of a boolean switch statement (field zero or non-zero).
1245 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
1246 switch/table generation ability of igen.
1248 * igen.c (idecode_switch_leaf): Fix code output when a switch
1249 statement needs to look up a table.
1251 * igen.c (idecode_declare_if_switch): New function called from
1252 gen_idecode_c - need to declare any idecode switch functions
1253 before they are used in idecode tables.
1255 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
1256 idecode_crack_insn): Add is_inline_function argument to code
1257 printing cracker functions which indicates if STATIC_IDECODE or
1258 STATIC_INLINE_IDECODE should be used for definition. For
1259 idecode_crack_insn (which implies not duplicating/expanding) don't
1260 declare function as inline - we assume that the only time this is
1261 code is generated is when things are being tested. For
1262 idecode_crack_leaf, make static (instead of INLINE) if the
1263 instructions parent is a table as function will always be called
1266 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
1267 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
1268 called directly, all others are called via a table.
1270 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
1271 semantics_h_insn, semantics_h_function,
1272 lf_print_c_semantic_function, semantics_c_function): Add
1273 is_inline_function argument to lf_print_semantic_function_header
1274 to indicate if an inline or static function declaration/definition
1275 should be output. Depending on situtation call accordingly:
1276 functions (not instruction semantic routines) are always inline;
1277 Semantic routines are made inline when there is no icache (cache
1278 will contain the function address) and are duplicating (see above)
1279 and the parent of the instruction is a switch statement.
1281 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
1282 and moved to insn_table_find_opcode_field.
1284 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
1286 * igen.c (model_c_insn): Suggestion - document the name of the
1287 instruction on each line of the instruction model table.
1289 Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au>
1291 * emul_netbsd.c (do_ioctl): Cleanup compilation.
1293 * sim_callbacks.h (__attribute__): Only define if not defined (was
1294 already defined on NetBSD host).
1296 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
1298 * std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New
1299 macro, indicates if the PowerPC's horrible XOR endian mode should
1300 be suported. Add to configure and make.
1302 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
1303 (vm_instruction_map_read): If XOR endian, xor the address
1304 with a value from an xor table (indexed by size of access).
1306 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
1307 set up xor table to xor if there is a conflict between the
1308 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
1309 check of suported change of endian mode from cpu.c to vm.c.
1311 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
1312 Hopefully added correct hack to handle XOR endian mode.
1314 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
1315 little endian mode, the model accepts miss aligned transfers.
1317 FIXME: Need to create an `init' device that, during
1318 initializatioin for XOR mode, it mushes (XOR address) all the dma
1319 data before passing it on to the core for storage. Just like the
1322 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
1324 * devices.c (halt_io_write_buffer_callback): Use value written to
1325 halt device to determine exit status. Thus allowing
1326 success/failure of OEA tests.
1328 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>

1913 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
1914 matched the compiled in ones.
1916 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -

1923 * ppc-instructions (mfsrin): Missing instruction
1924 * ppc-instructions (eieio): Missing instruction

1937 the instruction or data critical paths.
1939 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
1940 the inclusion of device_tree.c/emul_generic.c.
1944 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace
1945 system.[hc]. Start of suport for multiple emulations and
1946 emulation state (os_emul object).
1948 * emul_generic.[hc]: Start of code to implement proper system call
1953 * cpu.h, cpu.c (cpu_init): New function, zero the registers before
1954 the processor is started. Fixes problem of registers being
1955 undefined when restarting from within gdb.
1957 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
1958 instruction cache (if present). Fixes problem of cpu caching gdb
1959 breakpoint instructions.
1961 FIXME: PSIM sometimes aborts calling error(), it should instead
1962 call sim_error() say which takes care of housekeeping such as
1963 saving the CIA before calling error.
1965 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
1966 used when restarting a simulation because the latter has the
1967 unwanted side effect (well I as a kernel hacker think it is) of
1968 performing an isync when the instruction stream doesn't contain
1973 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
1974 monitoring module. Counts both instructions issued and
1977 * NOTE: mon does not contain to count instruction loads as this
1978 information is already available from the mon_issue() hook.
1980 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
1982 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
1983 a common monitor to each of the cpus. Delete
1984 cpu_increment_number_of_insns() and cpu_get_number_of_insns()
1985 replaced by copied code in mon.[hc].
1989 * sim_calls.c, main.c, psim.c (psim_create): always create
1990 `WITH_SMP' cpus. The actual number of CPU's active in a
1991 simulation run is taken from the device node: /init/smp (an
1992 integer). WITH_SMP changed to 2 (remember to put it back to 0).
1996 * system.c: More system call emulation. If code appears NetBSD
1997 specific, make conditional to being compiled on a NetBSD system
2002 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
2003 lf.[ch](new), table.[ch](new): Split into two generators - igen
2004 that outputs the instruction tables and dgen that outputs the spr
2005 tables. Add -f (filter out) flag to igen to filter out certain
2006 instructions (ex 64 bit ones) from the created tables. Include
2007 $(LIBIBERTY_LIB) in link options in case host lacks some libc
2010 * NOTE: igen, since it was originally written for the
2011 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
2013 * Makefile.in, std-config.h, ppc-cache-rules(new),
2014 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
2015 cache-rule and opcode-rule tables from macros found std-config.h.
2016 Delete corresponding macro's from std-config.h.
2018 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
2019 an table of all the instructions. Code to output a type
2020 enumerating all the instructin names.
2022 * igen.c(lf_print_c_semantic): Move call to increment instruction
2023 counter so that it occures _after_ the instruction has been fully
2024 validated, was double counting illegal/invalid instructions. Add
2025 conditional so only compiled in when WITH_PROFILE enabled (enabled
2028 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
2029 itable.h, count individual instruction types not just total,
2030 adjust reporting functions to output this.
2032 * ppc-instructions (64 bit Load Doubleword with Update Indexed):
2033 Had 32./ instead of 31./
2035 * ppc-instructions (64 bit Store Double Word Conditional Indexed):
2036 bitrot - updated to use newer CR register operators.
2038 * ppc-instructions (64bit Floating Convert from Integer
2039 Doubleword): Correct call to Round_Float().
2043 * basics.h: #include "sim_callbacks.h" earlier so that its
2044 prototypes are declared in all other header files.
2046 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
2047 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
2050 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
2051 Add size of buffer argument to functions writing a string into a
2052 buffer. Check for buffer overflow.
2056 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing
2057 of each device. Make parameter names consistent so macros work.
2058 Use macro's in device functions.
2060 * device_tree.c, devices.h, devices.c: include path to device in a
2061 devices node when creating it.
2063 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.
2065 * core.c: add tracing of core-device, adjust parameter names in
2066 core functions to be consistent with those in devices*.
2070 * debug.h, debug.c (trace_option): New function. Parses the trace
2071 option, updating the trace array.
2073 * debug.h, debug.c (trace_usage): New function. Outputs the list
2074 of all possible trace options.
2076 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
2077 parse trace options specified with the simpler -t flag. Adjust
2082 * Makefile.in (clean): Delete *.i and *.out files.
2084 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
2085 macros for either assignment or return. Fix SWAP_8 to use a
2086 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
2087 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
2088 that hardwired swapping on/off, let optimizer delete dead code.
2090 * main.c (main): Add printf that we caught a signal and print out
2091 the failing address.
2095 * Makefile.in: Remove tabs from otherwise empty line.
2096 Confuses many non-GNU versions of "make".
2100 * Makefile.in (clean): Delete files produced by gen.
2104 * gen.c (lf_print_c_semantic_function): Move counting # of
2105 instructions here so it works with caching.
2106 (gen_idecode_c): Move from here.
2110 * gen.c, ppc-instructions, psim.c: Fix code for generating
2111 cracking instruction cache. Delete the code that cached just the
2112 result from doing an instruction lookup - this ran slower than no
2117 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
2119 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
2120 TCL when gdb is linked with the simulator.
2121 * debug.c (ppc_trace): Ditto.
2122 * sim_calls.c (sim_open): Change trace -> ppc_trace.
2123 * main.c (main): Ditto.
2125 * cpu.c (cpu_add_commas): Remove extra static.
2129 * Makefile.in (psim.o): Now that inlines are turned on, make
2130 psim.o depend on all sources.
2132 * cpu.c (cpu_add_commas): New function to format a long with
2134 (cpu_print_info): Use it to print number_of_insns.
2136 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
2138 (ENDIAN_N): If both target and host byte orders are known, don't
2139 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
2141 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
2142 to allow target specific H2T_n/T2H_n macros to be used.
2143 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
2144 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
2145 of the 3 instruction sequence that runs on 386s.
2147 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
2148 specified on the compile line.
2149 (WITH_BSWAP): If not defined, define as 0.
2151 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
2152 default inline support. Pass INLINE_CFLAGS when compiling.
2154 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
2155 INLINE_DEVICES since GCC doesn't like inline functions that
2156 accept variable arguments.
2157 (stack_ioctl_callback): Make function just static because GCC
2158 doesn't like inline functions that accept variable arguments.
2160 * devices.h (STATIC_DEVICES): Define as empty if not defined.
2162 * inline.c: Correct pathnames of included C files to match current
2165 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
2166 non-zero, define STATIC_DEVICES to be static.
2168 * std-config.h (INLINE): If GNU C and optimizing, define this as
2170 (DEFAULT_INLINE): If not defined, define as 0.
2171 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
2172 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
2173 ({SPREG,IDECODE}_INLINE): Ditto.
2177 * ppc-instructions: Initial cut of floating point suport added.
2178 Of note include - use of host IEEE floating point instructions,
2179 use of PowerPC manual pseudo code to handle the FPSCR. It is not
2180 currently a pretty sight.
2182 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
2183 merge into core.h, core.c, core_n.h. The type memory_map replaced
2184 with core_map. This removes a level of pointer indirection when
2185 translating an address.
2187 * memory_map.h, memory_map.c, memory_map_n.h: delete.
2189 * Makefile.in et.al (sorry): tweek to use new core, core_map and
2194 * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to
2195 most of the other functions in sim_calls.c.
2197 * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
2198 Add macros to better cover up `generic' code. Makes it possible
2199 to step through the generic code!
2201 * vm.c, vm_n.h, Makefile.in: ditto
2205 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
2206 callback interface so that there is a read/write buffer but no
2207 read/write_word. VEA default memory read/write handler sometimes
2208 couldn't resolve an access and of those some were for a memory
2209 fault and some were because gdb was making a bogus request.
2211 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
2212 eliminate transfer_mode (raw or cooked) parameter from read/write
2217 * ppc-instructions (fmul, fmuls): correct instruction format - had
2222 * psim.c, device_tree.h, device_tree.c, devices.c (printd_*,
2223 scand_*): new functions to parse/print fields in device names
2224 while hiding any machine dependency.
2226 * devices.c, psim.c: Change the stack init code so that it is
2227 handled by a device. Arguments passed across using a device ioctl
2230 * devices.h, devices.c: device ioctl callback changed to allow a
2231 variable number of arguments. This gives greater flexability and
2232 greater chance of bugs.
2236 * main.c (printf_filtered, error): Missing va_end() to close off
2237 variable argument use.
2239 * Makefile.in (tmp-gencode): comment out hack to get around some
2240 versions of make not handling files being created as side-effects.
2242 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
2243 alternative file name to use in output files for things like #line
2246 Makefile.in (tmp-gencode): Use gen -n so that debug info is
2249 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the
2254 * sim_calls.c (sim_set_callbacks): Define new function.
2258 * psim.c (psim_print_info): Print exit status or signal number.
2262 * cpu.c (struct _cpu): Add number_of_insns field to trace how many
2263 instructions are executed.
2264 (cpu_increment_number_of_insns): New function to increment the
2265 number of instructions issued.
2266 (cpu_get_number_of_insns): New function to return the number of
2267 instructions issued.
2268 (cpu_print_info): New function to print cpu related information.
2269 At present, print the number of instructions executed.
2271 * gen_idecode_c: Emit call to cpu_increment_number_of_insns within
2274 * psim.c (psim_print_info): New function to iterate over each of
2275 the CPU's calling cpu_print_info.
2277 * psim.h,cpu.h: Add new declarations.
2279 * sim_calls.c (sim_open): Add argument processing to add the same
2280 switches main.c accepts for the standalone processor.
2281 (sim_close): Call psim_print_info if -I.
2283 * main.c (main): Add comment saying to update sim_calls.c when
2284 adding switches. Add -I to call psim_print_info when done.
2285 (usage): Update usage message.
2289 * main.c (printf_filtered): Correct to match new prototype.
2293 * sim_callbacks.h (printf_filtered): Correct prototype.
2297 * device_tree.c (OEA_MEMORY_SIZE): Define if not defined to
2299 (clayton_memory_size): Define as OEA_MEMORY_SIZE.
2301 * std-config.h (WITH_TRACE): Default to 1 now.
2303 * psim.c (write_stack_arguments): Don't write any stack arguments
2306 * main.c (main): Switch to using getopt. Make -p also set
2307 trace_semantics. Make -a turn on all trace flags. Make -C turn
2310 * device_tree.c (create_option_device_node): Assume a program is
2311 OEA if the start address is < 4096, not just == 0.
2315 * Makefile.in (maintainer-clean): New synonym for realclean.
2319 * registers.c (register_description): Add gdb synonyms for cr
2324 * Makefile.in (install): Don't install in $(tooldir).
2326 * configure.in: Call AC_CONFIG_HEADER. Don't try to use
2327 bfd/hosts/*.h file or bfd/config/*.mh file. Call AC_PROG_CC and
2328 AC_PROG_RANLIB. Substitute in values for CFLAGS, HDEFINES, AR,
2329 and CC_FOR_BUILD. Call AC_CHECK_HEADERS for various header files.
2330 Touch stamp.h if creating config.h.
2331 * configure: Rebuild.
2332 * config.in: New file, created by autoheader.
2333 * Makefile.in (AR): Define as @AR@.
2334 (CC): New variable, defined as @CC@.
2335 (CFLAGS): Define as @CFLAGS@.
2336 (CC_FOR_BUILD): New variable, defined as @CC_FOR_BUILD@.

2341 (clean): Remove config.log.
2342 (distclean): Remove config.h and stamp-h.
2343 (Makefile): Don't depend upon @frags@. Just rebuild Makefile when
2344 invoking config.status.
2345 (config.h, stamp-h): New targets.
2346 (gen, gen.o): Build with CC_FOR_BUILD, not CC.
2347 (ppc-config.h): Rename from old config.h build.
2348 * (basics.h,gen.c,ppc-endian.c,psim.c): Include ppc-config.h.
2352 * configure{,.in}: Don't include sysdep.h from bfd, since bfd no
2354 * basics.h (sysdep.h): Don't include it.
2355 * Makefile.in (BASICS_H): Remove sysdep.h.
2359 * core.c (core_add_data): First growth of bss was being put at
2360 wrong address (0) instead of &end.
2362 * core.c (core_add_stack, core_add_data): Was not handling case
2363 where bss/stack is grown across the current end-of-{bss,stack}.
2367 * system.c (system_call): Fix SYS_break - was aligning bss to a
2368 page boundary instead of just an 8 byte one; On first call sbrk(0)
2373 * Makefile.in (install): Fix install rule.
2377 * system.c (system_call): Add read support.
2379 * main.c (main): -t sets trace_device_tree. Correct usage message
2382 * device_tree.c (update_memory_node_for_section): Make tracing
2383 output line up. If not code or readonly, assume that the section
2384 is a data section and has read/write permissions. Add readonly
2387 * core.c (create_core_from_addresses): Print end address in traces
2388 and make tracing output line up.
2390 * Makefile.in: Rewrite from Makefile to work with the Cygnus
2391 environment, and support compiling in a different directory than
2392 the sources reside in.
2394 * ppc-endian.h: Rename from endian.h so that it doesn't get
2395 confused with /usr/include/sys/endian.h on Linux. Add Linux
2398 * ppc-endian.c: Rename to be consistant with ppc-endian.h.
2399 Include ppc-endian.h, not endian.h.
2401 * basics.h (sysdep.h): Include sysdep.h that configure makes.
2402 Include ppc-endian.h, not endian.h.
2404 * std-config.h: Rename from ppc-config. Put #ifndefs around most
2405 configuration macros, so they can be overridden via CFLAGS. By
2406 default, turn off tracing.
2408 * configure.in: Clone from other simulator targets.
2409 * configure: Generate via autoconf from configure.in.
2413 * ppc-instructions: fix srawi (was geting XER[CA] real wrong).
2415 * interrupts.c (data_storage_interrupt): allow stack to grow by
2416 upto one MB per increment.
2418 * ppc-instructions: divw was computing rA / rA not rA / rB
2420 * main.c (main): really stupid. Wasn't exiting with correct status
2424 * system.c (system_call): add system calls kill(2) and getpid(2).
2426 * main.c (main): Check/return exit status when simulation
2431 * device_tree.c (create_option_device_node): Alignment rules (at
2432 least for the moment) now are for strict alignment only for LE OEA
2433 mode. (Because of compiler problems).
2435 * system.c (system_call) SYS_exit: Wasn't exiting with correct status.
2439 * vm.c (DEFINE_VM_DATA_MAP_WRITE_N): For miss aligned transfer
2442 * system.c (system_call): didn't page align break argument before
2443 determining increment break increment.
2445 * psim/ppc: Re-arange entire directory structure so that
2446 everything lives in the one directory. While a pain for cleaning,
2447 makes building across multiple architectures much simpler.
2449 * devices.c, device_tree.c: Added code that provides a simple
2450 illustration of how an interrupt control device could be
2453 * devices.c: Added code so that the dumb console device can read
2454 (from stdin) as well as write to stdout.
