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

163 conditional branches that fell through.
165 Wed Nov 15 17:32:13 1995 Michael Meissner <meissner@tiktok.cygnus.com>

237 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
238 inline.. Only problem being that with ppc-opcode-simple this gave
239 it the chance to inline all the idecode functions with potentially
240 disasterous results on a 16mb PC. For moment hobble INLINE.
242 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
245 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
246 Firstly make them errors and secondly remove the options gcc-245
249 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
251 * misc.c (zalloc), cpu.c (cpu_init), devices
252 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
253 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
254 sim_calls.c (zalloc) : replace bzero() with memset().
256 * emul_netbsd.c (write_direntries), psim.c (psim_read_register,

259 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
261 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
262 force DEFAULT_INLINE to 0 rather then trusting the std
265 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
267 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
268 generation of switch entries in tables - treat the same as
269 cracking/semantic functions.
271 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
272 of a boolean switch statement (field zero or non-zero).
274 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
275 switch/table generation ability of igen.
277 * igen.c (idecode_switch_leaf): Fix code output when a switch
278 statement needs to look up a table.
280 * igen.c (idecode_declare_if_switch): New function called from
281 gen_idecode_c - need to declare any idecode switch functions
282 before they are used in idecode tables.
284 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
285 idecode_crack_insn): Add is_inline_function argument to code
286 printing cracker functions which indicates if STATIC_IDECODE or
287 STATIC_INLINE_IDECODE should be used for definition. For
288 idecode_crack_insn (which implies not duplicating/expanding) don't
289 declare function as inline - we assume that the only time this is
290 code is generated is when things are being tested. For
291 idecode_crack_leaf, make static (instead of INLINE) if the
292 instructions parent is a table as function will always be called
295 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
296 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
297 called directly, all others are called via a table.
299 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
300 semantics_h_insn, semantics_h_function,
301 lf_print_c_semantic_function, semantics_c_function): Add
302 is_inline_function argument to lf_print_semantic_function_header
303 to indicate if an inline or static function declaration/definition
304 should be output. Depending on situtation call accordingly:
305 functions (not instruction semantic routines) are always inline;
306 Semantic routines are made inline when there is no icache (cache
307 will contain the function address) and are duplicating (see above)
308 and the parent of the instruction is a switch statement.
310 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
311 and moved to insn_table_find_opcode_field.
313 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
315 * igen.c (model_c_insn): Suggestion - document the name of the
316 instruction on each line of the instruction model table.
318 Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au>
320 * emul_netbsd.c (do_ioctl): Cleanup compilation.
322 * sim_callbacks.h (__attribute__): Only define if not defined (was
323 already defined on NetBSD host).

328 macro, indicates if the PowerPC's horrible XOR endian mode should
329 be suported. Add to configure and make.
331 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
332 (vm_instruction_map_read): If XOR endian, xor the address
333 with a value from an xor table (indexed by size of access).
335 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
336 set up xor table to xor if there is a conflict between the
337 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
338 check of suported change of endian mode from cpu.c to vm.c.
340 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
341 Hopefully added correct hack to handle XOR endian mode.
343 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
344 little endian mode, the model accepts miss aligned transfers.
346 FIXME: Need to create an `init' device that, during
347 initializatioin for XOR mode, it mushes (XOR address) all the dma
348 data before passing it on to the core for storage. Just like the
351 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
353 * devices.c (halt_io_write_buffer_callback): Use value written to
354 halt device to determine exit status. Thus allowing
355 success/failure of OEA tests.
357 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>
359 * ppc-instructions (icbi): If icache present flush it.
361 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
363 * devices.c (htab_init_callback): Add code to create htab/pte.
365 * devices.c (dma_file, file_init_callback, htab_init_callback):
366 New function - Dma the named file into memory at the specified

371 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
373 * filter_filename.c, Makefile.in: Change so that only dependant on
374 a very limited nr of files. Stops an unnecessary dependency.
376 Tue Nov 7 15:44:33 1995 Andrew Cagney <cagney@highland.com.au>
378 * core.c (core_map_find_mapping): Use cpu_halt rather than error
379 to abort an access to an undefined address.
381 Sun Nov 12 07:58:09 1995 Michael Meissner <meissner@tiktok.cygnus.com>

438 * igen.c (semantics_h_print_function): Emit STATIC_SEMANTICS
439 instead of INLINE_SEMANTICS so that the compiler won't keep all of
440 the semantic functions as inline RTL, given that the address of
441 the function is taken which forces outline calls anyway.

833 functions to convert between target and igen internal bit numbers.
834 Make IO go through these functions. Add -b (bit size) and -h (high

836 15 for a 16 bit instruction format with the msb given a number 15.
838 Wed Nov 1 22:17:32 1995 Andrew Cagney <cagney@highland.com.au>
840 * dgen.c (main): Was outputting optarg even when it was NULL.

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

928 * std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC
929 and optimizing by default.
931 Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au>
933 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
934 make them functions again. Appears 2.6.3 is confused by just a
937 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
939 * ppc-endian.c (SWAP_8): Fix 8 byte swap!
941 * psim.c (psim_create): Not correctly checking that runtime
942 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
943 matched the compiled in ones.
945 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
946 trace_semantics is now different to trace_idecode, the former

951 * ppc-instructions (mtsrin): Missing instruction
952 * ppc-instructions (mfsrin): Missing instruction

962 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
963 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
964 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
965 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
966 the instruction or data critical paths.
968 * FIXME: need to set up OS_EMUL_INLINE/EMUL_GENERIC_INLINE but
969 not on critical path.
971 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
972 the inclusion of device_tree.c/emul_generic.c.
974 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
976 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace

986 the processor is started. Fixes problem of registers being
987 undefined when restarting from within gdb.
989 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
990 instruction cache (if present). Fixes problem of cpu caching gdb
991 breakpoint instructions.
993 FIXME: PSIM sometimes aborts calling error(), it should instead
994 call sim_error() say which takes care of housekeeping such as
995 saving the CIA before calling error.
997 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
998 used when restarting a simulation because the latter has the
999 unwanted side effect (well I as a kernel hacker think it is) of
1000 performing an isync when the instruction stream doesn't contain
1003 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
1005 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
1006 monitoring module. Counts both instructions issued and
1009 * NOTE: mon does not contain to count instruction loads as this
1010 information is already available from the mon_issue() hook.
1012 * FIXME: mon doesn't have access to register usage information.
1013 This is needed if the user wants to monitor things like register
1016 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
1018 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
1019 a common monitor to each of the cpus. Delete
1020 cpu_increment_number_of_insns() and cpu_get_number_of_insns()
1021 replaced by copied code in mon.[hc].
1023 Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au>
1025 * sim_calls.c, main.c, psim.c (psim_create): always create
1026 `WITH_SMP' cpus. The actual number of CPU's active in a
1027 simulation run is taken from the device node: /init/smp (an
1028 integer). WITH_SMP changed to 2 (remember to put it back to 0).
1030 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
1032 * system.c: More system call emulation. If code appears NetBSD

1038 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
1039 lf.[ch](new), table.[ch](new): Split into two generators - igen
1040 that outputs the instruction tables and dgen that outputs the spr
1041 tables. Add -f (filter out) flag to igen to filter out certain
1042 instructions (ex 64 bit ones) from the created tables. Include
1043 $(LIBIBERTY_LIB) in link options in case host lacks some libc
1046 * NOTE: igen, since it was originally written for the
1047 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
1049 * Makefile.in, std-config.h, ppc-cache-rules(new),
1050 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
1051 cache-rule and opcode-rule tables from macros found std-config.h.
1052 Delete corresponding macro's from std-config.h.
1054 * FIXME: under this new igen scheme, when playing around with igen
1055 options, you'll find that depenencies don't work very well.
1057 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
1058 an table of all the instructions. Code to output a type
1059 enumerating all the instructin names.
1061 * igen.c(lf_print_c_semantic): Move call to increment instruction
1062 counter so that it occures _after_ the instruction has been fully
1063 validated, was double counting illegal/invalid instructions. Add
1064 conditional so only compiled in when WITH_PROFILE enabled (enabled
1067 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
1068 itable.h, count individual instruction types not just total,
1069 adjust reporting functions to output this.
1071 * ppc-instructions (64 bit Load Doubleword with Update Indexed):
1072 Had 32./ instead of 31./
1074 * ppc-instructions (64 bit Store Double Word Conditional Indexed):
1075 bitrot - updated to use newer CR register operators.
1077 * ppc-instructions (64bit Floating Convert from Integer
1078 Doubleword): Correct call to Round_Float().
1080 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
1082 * basics.h: #include "sim_callbacks.h" earlier so that its
1083 prototypes are declared in all other header files.
1085 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
1086 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
1089 * FIXME: the bits.h/bits.c macro's should be replaced with
1090 (inline) c functions.
1092 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
1093 Add size of buffer argument to functions writing a string into a
1094 buffer. Check for buffer overflow.
1096 Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au>
1098 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing
1099 of each device. Make parameter names consistent so macros work.

1103 devices node when creating it.
1105 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.

1112 * debug.h, debug.c (trace_option): New function. Parses the trace
1113 option, updating the trace array.
1115 * debug.h, debug.c (trace_usage): New function. Outputs the list
1116 of all possible trace options.
1118 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
1119 parse trace options specified with the simpler -t flag. Adjust
1122 * FIXME: basic parsing of command line options is still duplicated
1123 by main.c and sim_calls.c

1127 * Makefile.in (clean): Delete *.i and *.out files.
1129 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
1130 macros for either assignment or return. Fix SWAP_8 to use a
1131 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
1132 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
1133 that hardwired swapping on/off, let optimizer delete dead code.
1135 * main.c (main): Add printf that we caught a signal and print out
1136 the failing address.
1138 Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>
1140 * Makefile.in: Remove tabs from otherwise empty line.
1141 Confuses many non-GNU versions of "make".
1143 Wed Oct 18 08:51:25 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1145 * Makefile.in (clean): Delete files produced by gen.
1147 Mon Oct 16 17:34:24 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1149 * gen.c (lf_print_c_semantic_function): Move counting # of
1150 instructions here so it works with caching.
1151 (gen_idecode_c): Move from here.
1153 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1155 * gen.c, ppc-instructions, psim.c: Fix code for generating
1156 cracking instruction cache. Delete the code that cached just the
1157 result from doing an instruction lookup - this ran slower than no
1160 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1162 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
1164 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
1165 TCL when gdb is linked with the simulator.
1166 * debug.c (ppc_trace): Ditto.
1167 * sim_calls.c (sim_open): Change trace -> ppc_trace.
1168 * main.c (main): Ditto.

1172 Thu Oct 12 11:35:53 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1174 * Makefile.in (psim.o): Now that inlines are turned on, make
1175 psim.o depend on all sources.
1177 * cpu.c (cpu_add_commas): New function to format a long with
1179 (cpu_print_info): Use it to print number_of_insns.
1181 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
1183 (ENDIAN_N): If both target and host byte orders are known, don't
1184 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
1186 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
1187 to allow target specific H2T_n/T2H_n macros to be used.
1188 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
1189 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
1190 of the 3 instruction sequence that runs on 386s.
1192 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
1193 specified on the compile line.
1194 (WITH_BSWAP): If not defined, define as 0.
1196 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
1197 default inline support. Pass INLINE_CFLAGS when compiling.
1199 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
1200 INLINE_DEVICES since GCC doesn't like inline functions that
1201 accept variable arguments.
1202 (stack_ioctl_callback): Make function just static because GCC
1203 doesn't like inline functions that accept variable arguments.
1205 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1207 * inline.c: Correct pathnames of included C files to match current
1210 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1211 non-zero, define STATIC_DEVICES to be static.
1213 * std-config.h (INLINE): If GNU C and optimizing, define this as
1215 (DEFAULT_INLINE): If not defined, define as 0.
1216 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1217 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
1218 ({SPREG,IDECODE}_INLINE): Ditto.
1220 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1222 * ppc-instructions: Initial cut of floating point suport added.
1223 Of note include - use of host IEEE floating point instructions,
1224 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1225 currently a pretty sight.
1227 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1228 merge into core.h, core.c, core_n.h. The type memory_map replaced
1229 with core_map. This removes a level of pointer indirection when
1230 translating an address.
1232 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1234 * Makefile.in et.al (sorry): tweek to use new core, core_map and

1240 most of the other functions in sim_calls.c.
1242 * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
1243 Add macros to better cover up `generic' code. Makes it possible
1244 to step through the generic code!
1246 * vm.c, vm_n.h, Makefile.in: ditto
1248 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
1250 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1251 callback interface so that there is a read/write buffer but no
1252 read/write_word. VEA default memory read/write handler sometimes
1253 couldn't resolve an access and of those some were for a memory
1254 fault and some were because gdb was making a bogus request.
1256 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
1257 eliminate transfer_mode (raw or cooked) parameter from read/write
1260 Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>
1262 * ppc-instructions (fmul, fmuls): correct instruction format - had
1265 Wed Oct 4 17:31:12 1995 Andrew Cagney <cagney@highland.com.au>
1267 * psim.c, device_tree.h, device_tree.c, devices.c (printd_*,
1268 scand_*): new functions to parse/print fields in device names
1269 while hiding any machine dependency.
1271 * devices.c, psim.c: Change the stack init code so that it is
1272 handled by a device. Arguments passed across using a device ioctl
1275 * devices.h, devices.c: device ioctl callback changed to allow a
1276 variable number of arguments. This gives greater flexability and
1277 greater chance of bugs.
1279 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
1281 * main.c (printf_filtered, error): Missing va_end() to close off
1282 variable argument use.
1284 * Makefile.in (tmp-gencode): comment out hack to get around some
1285 versions of make not handling files being created as side-effects.
1287 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
1288 alternative file name to use in output files for things like #line
1291 Makefile.in (tmp-gencode): Use gen -n so that debug info is
1294 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the

1314 At present, print the number of instructions executed.
1316 * gen_idecode_c: Emit call to cpu_increment_number_of_insns within
1319 * psim.c (psim_print_info): New function to iterate over each of
1320 the CPU's calling cpu_print_info.
1322 * psim.h,cpu.h: Add new declarations.
1324 * sim_calls.c (sim_open): Add argument processing to add the same
1325 switches main.c accepts for the standalone processor.
1326 (sim_close): Call psim_print_info if -I.
1328 * main.c (main): Add comment saying to update sim_calls.c when
1329 adding switches. Add -I to call psim_print_info when done.

1351 * main.c (main): Switch to using getopt. Make -p also set
1352 trace_semantics. Make -a turn on all trace flags. Make -C turn
1355 * device_tree.c (create_option_device_node): Assume a program is
1356 OEA if the start address is < 4096, not just == 0.

1402 Wed Sep 6 13:25:42 1995 Andrew Cagney <cagney@highland.com.au>
1404 * core.c (core_add_data): First growth of bss was being put at
1405 wrong address (0) instead of &end.
1407 * core.c (core_add_stack, core_add_data): Was not handling case
1408 where bss/stack is grown across the current end-of-{bss,stack}.
1410 Wed Sep 6 00:46:10 1995 Andrew Cagney <cagney@highland.com.au>
1412 * system.c (system_call): Fix SYS_break - was aligning bss to a
