75 (lf_print_c_semantic_function): If -R, #undef all of the names
76 defined in lf_print_c_extraction.
79 * idecode_fields.h (SPR_*): Redefine spr_* macros as SPR_* to
80 avoid a name confict if -R passed to igen.

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

146 * cpu.c (cpu_{create,init,halt}): Check for WITH_MODEL_ISSUE
147 before calling the model functions.

216 instructions, rather than testing it in model_issue. Add code to
217 code successful/unsuccessful branch predictions, and the number of
218 conditional branches that fell through.
220 Wed Nov 15 17:32:13 1995 Michael Meissner <meissner@tiktok.cygnus.com>
222 * cpu.h (cpu_model): Add declaration.

290 Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
292 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
293 inline.. Only problem being that with ppc-opcode-simple this gave
294 it the chance to inline all the idecode functions with potentially
295 disasterous results on a 16mb PC. For moment hobble INLINE.
297 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
300 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
301 Firstly make them errors and secondly remove the options gcc-245
304 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
306 * misc.c (zalloc), cpu.c (cpu_init), devices
307 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
308 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
309 sim_calls.c (zalloc) : replace bzero() with memset().
311 * emul_netbsd.c (write_direntries), psim.c (psim_read_register,
312 psim_write_register): replace bcopy() with memcpy().
314 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
316 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
317 force DEFAULT_INLINE to 0 rather then trusting the std
320 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
322 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
323 generation of switch entries in tables - treat the same as
324 cracking/semantic functions.
326 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
327 of a boolean switch statement (field zero or non-zero).
329 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
330 switch/table generation ability of igen.
332 * igen.c (idecode_switch_leaf): Fix code output when a switch
333 statement needs to look up a table.
335 * igen.c (idecode_declare_if_switch): New function called from
336 gen_idecode_c - need to declare any idecode switch functions
337 before they are used in idecode tables.
339 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
340 idecode_crack_insn): Add is_inline_function argument to code
341 printing cracker functions which indicates if STATIC_IDECODE or
342 STATIC_INLINE_IDECODE should be used for definition. For
343 idecode_crack_insn (which implies not duplicating/expanding) don't
344 declare function as inline - we assume that the only time this is
345 code is generated is when things are being tested. For
346 idecode_crack_leaf, make static (instead of INLINE) if the
347 instructions parent is a table as function will always be called
350 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
351 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
352 called directly, all others are called via a table.
354 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
355 semantics_h_insn, semantics_h_function,
356 lf_print_c_semantic_function, semantics_c_function): Add
357 is_inline_function argument to lf_print_semantic_function_header
358 to indicate if an inline or static function declaration/definition
359 should be output. Depending on situtation call accordingly:
360 functions (not instruction semantic routines) are always inline;
361 Semantic routines are made inline when there is no icache (cache
362 will contain the function address) and are duplicating (see above)
363 and the parent of the instruction is a switch statement.
365 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
366 and moved to insn_table_find_opcode_field.
368 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
370 * igen.c (model_c_insn): Suggestion - document the name of the
371 instruction on each line of the instruction model table.
373 Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au>
375 * emul_netbsd.c (do_ioctl): Cleanup compilation.
377 * sim_callbacks.h (__attribute__): Only define if not defined (was
378 already defined on NetBSD host).
380 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
382 * std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New
383 macro, indicates if the PowerPC's horrible XOR endian mode should
384 be suported. Add to configure and make.
386 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
387 (vm_instruction_map_read): If XOR endian, xor the address
388 with a value from an xor table (indexed by size of access).
390 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
391 set up xor table to xor if there is a conflict between the
392 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
393 check of suported change of endian mode from cpu.c to vm.c.
395 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
396 Hopefully added correct hack to handle XOR endian mode.
398 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
399 little endian mode, the model accepts miss aligned transfers.
401 FIXME: Need to create an `init' device that, during
402 initializatioin for XOR mode, it mushes (XOR address) all the dma
403 data before passing it on to the core for storage. Just like the
406 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
408 * devices.c (halt_io_write_buffer_callback): Use value written to
409 halt device to determine exit status. Thus allowing
410 success/failure of OEA tests.
412 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>
414 * ppc-instructions (icbi): If icache present flush it.
416 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
418 * devices.c (htab_init_callback): Add code to create htab/pte.
420 * devices.c (dma_file, file_init_callback, htab_init_callback):
421 New function - Dma the named file into memory at the specified
424 * device_tree.h, device_tree.c (scand_*): New functions.
426 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
428 * filter_filename.c, Makefile.in: Change so that only dependant on
429 a very limited nr of files. Stops an unnecessary dependency.
431 Tue Nov 7 15:44:33 1995 Andrew Cagney <cagney@highland.com.au>
433 * core.c (core_map_find_mapping): Use cpu_halt rather than error
434 to abort an access to an undefined address.

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

891 15 for a 16 bit instruction format with the msb given a number 15.
893 Wed Nov 1 22:17:32 1995 Andrew Cagney <cagney@highland.com.au>
895 * dgen.c (main): Was outputting optarg even when it was NULL.

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

984 and optimizing by default.
986 Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au>
988 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
989 make them functions again. Appears 2.6.3 is confused by just a
992 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
994 * ppc-endian.c (SWAP_8): Fix 8 byte swap!
996 * psim.c (psim_create): Not correctly checking that runtime
997 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
998 matched the compiled in ones.
1000 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
1001 trace_semantics is now different to trace_idecode, the former

1017 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
1018 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
1019 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
1020 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
1021 the instruction or data critical paths.
1023 * FIXME: need to set up OS_EMUL_INLINE/EMUL_GENERIC_INLINE but
1024 not on critical path.
1026 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
1027 the inclusion of device_tree.c/emul_generic.c.
1029 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
1031 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace

1042 undefined when restarting from within gdb.
1044 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
1045 instruction cache (if present). Fixes problem of cpu caching gdb
1046 breakpoint instructions.
1048 FIXME: PSIM sometimes aborts calling error(), it should instead
1049 call sim_error() say which takes care of housekeeping such as
1050 saving the CIA before calling error.
1052 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
1053 used when restarting a simulation because the latter has the
1054 unwanted side effect (well I as a kernel hacker think it is) of
1055 performing an isync when the instruction stream doesn't contain
1058 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
1060 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
1061 monitoring module. Counts both instructions issued and
1064 * NOTE: mon does not contain to count instruction loads as this
1065 information is already available from the mon_issue() hook.
1067 * FIXME: mon doesn't have access to register usage information.
1068 This is needed if the user wants to monitor things like register
1071 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
1073 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
1074 a common monitor to each of the cpus. Delete
1075 cpu_increment_number_of_insns() and cpu_get_number_of_insns()
1076 replaced by copied code in mon.[hc].
1078 Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au>
1080 * sim_calls.c, main.c, psim.c (psim_create): always create
1081 `WITH_SMP' cpus. The actual number of CPU's active in a
1082 simulation run is taken from the device node: /init/smp (an
1083 integer). WITH_SMP changed to 2 (remember to put it back to 0).
1085 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
1087 * system.c: More system call emulation. If code appears NetBSD

1093 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
1094 lf.[ch](new), table.[ch](new): Split into two generators - igen
1095 that outputs the instruction tables and dgen that outputs the spr
1096 tables. Add -f (filter out) flag to igen to filter out certain
1097 instructions (ex 64 bit ones) from the created tables. Include
1098 $(LIBIBERTY_LIB) in link options in case host lacks some libc
1101 * NOTE: igen, since it was originally written for the
1102 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
1104 * Makefile.in, std-config.h, ppc-cache-rules(new),
1105 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
1106 cache-rule and opcode-rule tables from macros found std-config.h.
1107 Delete corresponding macro's from std-config.h.
1109 * FIXME: under this new igen scheme, when playing around with igen
1110 options, you'll find that depenencies don't work very well.
1112 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
1113 an table of all the instructions. Code to output a type
1114 enumerating all the instructin names.
1116 * igen.c(lf_print_c_semantic): Move call to increment instruction
1117 counter so that it occures _after_ the instruction has been fully
1118 validated, was double counting illegal/invalid instructions. Add
1119 conditional so only compiled in when WITH_PROFILE enabled (enabled
1122 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
1123 itable.h, count individual instruction types not just total,
1124 adjust reporting functions to output this.
1126 * ppc-instructions (64 bit Load Doubleword with Update Indexed):

1132 * ppc-instructions (64bit Floating Convert from Integer
1133 Doubleword): Correct call to Round_Float().
1135 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
1137 * basics.h: #include "sim_callbacks.h" earlier so that its
1138 prototypes are declared in all other header files.
1140 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
1141 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
1144 * FIXME: the bits.h/bits.c macro's should be replaced with
1145 (inline) c functions.
1147 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
1148 Add size of buffer argument to functions writing a string into a
1149 buffer. Check for buffer overflow.
1151 Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au>
1153 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing
1154 of each device. Make parameter names consistent so macros work.

1167 * debug.h, debug.c (trace_option): New function. Parses the trace
1168 option, updating the trace array.
1170 * debug.h, debug.c (trace_usage): New function. Outputs the list
1171 of all possible trace options.
1173 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
1174 parse trace options specified with the simpler -t flag. Adjust
1177 * FIXME: basic parsing of command line options is still duplicated
1178 by main.c and sim_calls.c

1182 * Makefile.in (clean): Delete *.i and *.out files.
1184 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
1185 macros for either assignment or return. Fix SWAP_8 to use a
1186 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
1187 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
1188 that hardwired swapping on/off, let optimizer delete dead code.
1190 * main.c (main): Add printf that we caught a signal and print out
1191 the failing address.
1193 Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>
1195 * Makefile.in: Remove tabs from otherwise empty line.

1211 cracking instruction cache. Delete the code that cached just the
1212 result from doing an instruction lookup - this ran slower than no
1215 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1217 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
1219 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with

1234 (cpu_print_info): Use it to print number_of_insns.
1236 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
1238 (ENDIAN_N): If both target and host byte orders are known, don't
1239 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
1241 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
1242 to allow target specific H2T_n/T2H_n macros to be used.
1243 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
1244 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
1245 of the 3 instruction sequence that runs on 386s.
1247 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
1248 specified on the compile line.
1249 (WITH_BSWAP): If not defined, define as 0.

1252 default inline support. Pass INLINE_CFLAGS when compiling.
1254 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
1255 INLINE_DEVICES since GCC doesn't like inline functions that
1256 accept variable arguments.
1257 (stack_ioctl_callback): Make function just static because GCC
1258 doesn't like inline functions that accept variable arguments.
1260 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1262 * inline.c: Correct pathnames of included C files to match current
1265 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1266 non-zero, define STATIC_DEVICES to be static.
1268 * std-config.h (INLINE): If GNU C and optimizing, define this as
1270 (DEFAULT_INLINE): If not defined, define as 0.
1271 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1272 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.

1275 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1277 * ppc-instructions: Initial cut of floating point suport added.
1278 Of note include - use of host IEEE floating point instructions,
1279 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1280 currently a pretty sight.
1282 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1283 merge into core.h, core.c, core_n.h. The type memory_map replaced
1284 with core_map. This removes a level of pointer indirection when
1285 translating an address.
1287 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1289 * Makefile.in et.al (sorry): tweek to use new core, core_map and

1299 to step through the generic code!
1301 * vm.c, vm_n.h, Makefile.in: ditto
1303 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
1305 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1306 callback interface so that there is a read/write buffer but no
1307 read/write_word. VEA default memory read/write handler sometimes
1308 couldn't resolve an access and of those some were for a memory
1309 fault and some were because gdb was making a bogus request.
1311 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
1312 eliminate transfer_mode (raw or cooked) parameter from read/write
1315 Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>
1317 * ppc-instructions (fmul, fmuls): correct instruction format - had

1323 scand_*): new functions to parse/print fields in device names
1324 while hiding any machine dependency.
1326 * devices.c, psim.c: Change the stack init code so that it is
1327 handled by a device. Arguments passed across using a device ioctl
1330 * devices.h, devices.c: device ioctl callback changed to allow a
1331 variable number of arguments. This gives greater flexability and
1332 greater chance of bugs.
1334 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
1336 * main.c (printf_filtered, error): Missing va_end() to close off
1337 variable argument use.
1339 * Makefile.in (tmp-gencode): comment out hack to get around some
1340 versions of make not handling files being created as side-effects.
1342 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
1343 alternative file name to use in output files for things like #line
1346 Makefile.in (tmp-gencode): Use gen -n so that debug info is
1349 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the

1369 At present, print the number of instructions executed.
1371 * gen_idecode_c: Emit call to cpu_increment_number_of_insns within
1374 * psim.c (psim_print_info): New function to iterate over each of
1375 the CPU's calling cpu_print_info.
1377 * psim.h,cpu.h: Add new declarations.
1379 * sim_calls.c (sim_open): Add argument processing to add the same
1380 switches main.c accepts for the standalone processor.
1381 (sim_close): Call psim_print_info if -I.
1383 * main.c (main): Add comment saying to update sim_calls.c when
1384 adding switches. Add -I to call psim_print_info when done.

1460 wrong address (0) instead of &end.
1462 * core.c (core_add_stack, core_add_data): Was not handling case
1463 where bss/stack is grown across the current end-of-{bss,stack}.
1465 Wed Sep 6 00:46:10 1995 Andrew Cagney <cagney@highland.com.au>
1467 * system.c (system_call): Fix SYS_break - was aligning bss to a
