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

123 instructions, rather than testing it in model_issue. Add code to
124 code successful/unsuccessful branch predictions, and the number of
125 conditional branches that fell through.
127 Wed Nov 15 17:32:13 1995 Michael Meissner <meissner@tiktok.cygnus.com>

199 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
200 inline.. Only problem being that with ppc-opcode-simple this gave
201 it the chance to inline all the idecode functions with potentially
202 disasterous results on a 16mb PC. For moment hobble INLINE.
204 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
207 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
208 Firstly make them errors and secondly remove the options gcc-245
211 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
213 * misc.c (zalloc), cpu.c (cpu_init), devices
214 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
215 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
216 sim_calls.c (zalloc) : replace bzero() with memset().

219 psim_write_register): replace bcopy() with memcpy().
221 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
223 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
224 force DEFAULT_INLINE to 0 rather then trusting the std
227 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
229 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
230 generation of switch entries in tables - treat the same as
231 cracking/semantic functions.
233 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
234 of a boolean switch statement (field zero or non-zero).
236 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
237 switch/table generation ability of igen.
239 * igen.c (idecode_switch_leaf): Fix code output when a switch
240 statement needs to look up a table.
242 * igen.c (idecode_declare_if_switch): New function called from
243 gen_idecode_c - need to declare any idecode switch functions
244 before they are used in idecode tables.
246 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
247 idecode_crack_insn): Add is_inline_function argument to code
248 printing cracker functions which indicates if STATIC_IDECODE or
249 STATIC_INLINE_IDECODE should be used for definition. For
250 idecode_crack_insn (which implies not duplicating/expanding) don't
251 declare function as inline - we assume that the only time this is
252 code is generated is when things are being tested. For
253 idecode_crack_leaf, make static (instead of INLINE) if the
254 instructions parent is a table as function will always be called
257 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
258 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
259 called directly, all others are called via a table.
261 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
262 semantics_h_insn, semantics_h_function,
263 lf_print_c_semantic_function, semantics_c_function): Add
264 is_inline_function argument to lf_print_semantic_function_header
265 to indicate if an inline or static function declaration/definition
266 should be output. Depending on situtation call accordingly:
267 functions (not instruction semantic routines) are always inline;
268 Semantic routines are made inline when there is no icache (cache
269 will contain the function address) and are duplicating (see above)
270 and the parent of the instruction is a switch statement.
272 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
273 and moved to insn_table_find_opcode_field.
275 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
277 * igen.c (model_c_insn): Suggestion - document the name of the
278 instruction on each line of the instruction model table.
280 Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au>
282 * emul_netbsd.c (do_ioctl): Cleanup compilation.
284 * sim_callbacks.h (__attribute__): Only define if not defined (was
285 already defined on NetBSD host).

289 * std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New
290 macro, indicates if the PowerPC's horrible XOR endian mode should
291 be suported. Add to configure and make.
293 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
294 (vm_instruction_map_read): If XOR endian, xor the address
295 with a value from an xor table (indexed by size of access).
297 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
298 set up xor table to xor if there is a conflict between the
299 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
300 check of suported change of endian mode from cpu.c to vm.c.
302 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
303 Hopefully added correct hack to handle XOR endian mode.
305 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
306 little endian mode, the model accepts miss aligned transfers.
308 FIXME: Need to create an `init' device that, during
309 initializatioin for XOR mode, it mushes (XOR address) all the dma
310 data before passing it on to the core for storage. Just like the
313 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
315 * devices.c (halt_io_write_buffer_callback): Use value written to
316 halt device to determine exit status. Thus allowing
317 success/failure of OEA tests.
319 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>
321 * ppc-instructions (icbi): If icache present flush it.

327 * devices.c (dma_file, file_init_callback, htab_init_callback):
328 New function - Dma the named file into memory at the specified

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

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

740 * Makefile.in: Uncomment built file dependencies.
742 * configure.in: Rewrite --enable-sim switch handling to use the
743 autoconf builtins so it works correctly if the configure or

746 supported. Check whether getrusage and sys/resource.h are
748 * config.in: Regenerate.

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

798 15 for a 16 bit instruction format with the msb given a number 15.
800 Wed Nov 1 22:17:32 1995 Andrew Cagney <cagney@highland.com.au>
802 * dgen.c (main): Was outputting optarg even when it was NULL.

822 Tue Oct 31 21:31:32 1995 Andrew Cagney <cagney@highland.com.au>
824 * ppc-opcode-stupid: Third example of use of opcode table - this
825 one expands all mtspr/mfspr and branch instructions. Appears to
826 give about a 10% gain in performance if everything enabled. Also
827 takes about 150mb of swap to build.
829 Wed Nov 1 10:49:48 1995 Michael Meissner <meissner@tiktok.cygnus.com>
831 * emul_netbsd.c (do_exit): Print arguments and close parenthesis

887 * Makefile.in: Add various Make variables that the various
890 * std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC
891 and optimizing by default.
893 Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au>
895 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
896 make them functions again. Appears 2.6.3 is confused by just a
899 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
901 * ppc-endian.c (SWAP_8): Fix 8 byte swap!
903 * psim.c (psim_create): Not correctly checking that runtime
904 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
905 matched the compiled in ones.
907 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
908 trace_semantics is now different to trace_idecode, the former

913 * ppc-instructions (mtsrin): Missing instruction
914 * ppc-instructions (mfsrin): Missing instruction

917 Tue Oct 24 20:55:29 1995 Andrew Cagney <cagney@highland.com.au>
919 * build-psim: New shell script - see internals for usage,
920 simplifies the process of building custom simulators.
922 Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney@highland.com.au>
924 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
925 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
926 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
927 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
928 the instruction or data critical paths.
930 * FIXME: need to set up OS_EMUL_INLINE/EMUL_GENERIC_INLINE but
931 not on critical path.
933 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
934 the inclusion of device_tree.c/emul_generic.c.
936 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
938 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace

948 the processor is started. Fixes problem of registers being
949 undefined when restarting from within gdb.
951 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
952 instruction cache (if present). Fixes problem of cpu caching gdb
953 breakpoint instructions.
955 FIXME: PSIM sometimes aborts calling error(), it should instead
956 call sim_error() say which takes care of housekeeping such as
957 saving the CIA before calling error.
959 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
960 used when restarting a simulation because the latter has the
961 unwanted side effect (well I as a kernel hacker think it is) of
962 performing an isync when the instruction stream doesn't contain
965 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
967 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
968 monitoring module. Counts both instructions issued and
971 * NOTE: mon does not contain to count instruction loads as this
972 information is already available from the mon_issue() hook.
974 * FIXME: mon doesn't have access to register usage information.
975 This is needed if the user wants to monitor things like register
978 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
980 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
981 a common monitor to each of the cpus. Delete
982 cpu_increment_number_of_insns() and cpu_get_number_of_insns()
983 replaced by copied code in mon.[hc].
985 Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au>
987 * sim_calls.c, main.c, psim.c (psim_create): always create
988 `WITH_SMP' cpus. The actual number of CPU's active in a
989 simulation run is taken from the device node: /init/smp (an
990 integer). WITH_SMP changed to 2 (remember to put it back to 0).
992 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
994 * system.c: More system call emulation. If code appears NetBSD
995 specific, make conditional to being compiled on a NetBSD system

1000 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
1001 lf.[ch](new), table.[ch](new): Split into two generators - igen
1002 that outputs the instruction tables and dgen that outputs the spr
1003 tables. Add -f (filter out) flag to igen to filter out certain
1004 instructions (ex 64 bit ones) from the created tables. Include
1005 $(LIBIBERTY_LIB) in link options in case host lacks some libc
1008 * NOTE: igen, since it was originally written for the
1009 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
1011 * Makefile.in, std-config.h, ppc-cache-rules(new),
1012 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
1013 cache-rule and opcode-rule tables from macros found std-config.h.
1014 Delete corresponding macro's from std-config.h.
1016 * FIXME: under this new igen scheme, when playing around with igen
1017 options, you'll find that depenencies don't work very well.
1019 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
1020 an table of all the instructions. Code to output a type
1021 enumerating all the instructin names.
1023 * igen.c(lf_print_c_semantic): Move call to increment instruction
1024 counter so that it occures _after_ the instruction has been fully
1025 validated, was double counting illegal/invalid instructions. Add
1026 conditional so only compiled in when WITH_PROFILE enabled (enabled
1029 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
1030 itable.h, count individual instruction types not just total,
1031 adjust reporting functions to output this.

1034 Had 32./ instead of 31./
1036 * ppc-instructions (64 bit Store Double Word Conditional Indexed):
1037 bitrot - updated to use newer CR register operators.
1039 * ppc-instructions (64bit Floating Convert from Integer
1040 Doubleword): Correct call to Round_Float().
1042 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
1044 * basics.h: #include "sim_callbacks.h" earlier so that its
1045 prototypes are declared in all other header files.
1047 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
1048 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into

1052 (inline) c functions.
1054 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
1055 Add size of buffer argument to functions writing a string into a
1056 buffer. Check for buffer overflow.
1058 Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au>
1060 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing

1065 devices node when creating it.
1067 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.

1074 * debug.h, debug.c (trace_option): New function. Parses the trace
1075 option, updating the trace array.
1077 * debug.h, debug.c (trace_usage): New function. Outputs the list
1078 of all possible trace options.
1080 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
1081 parse trace options specified with the simpler -t flag. Adjust
1084 * FIXME: basic parsing of command line options is still duplicated
1085 by main.c and sim_calls.c
1087 Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1089 * Makefile.in (clean): Delete *.i and *.out files.
1091 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
1092 macros for either assignment or return. Fix SWAP_8 to use a
1093 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
1094 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
1095 that hardwired swapping on/off, let optimizer delete dead code.
1097 * main.c (main): Add printf that we caught a signal and print out
1098 the failing address.

1112 instructions here so it works with caching.
1113 (gen_idecode_c): Move from here.
1115 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1117 * gen.c, ppc-instructions, psim.c: Fix code for generating
1118 cracking instruction cache. Delete the code that cached just the
1119 result from doing an instruction lookup - this ran slower than no
1122 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1124 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
1126 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
1127 TCL when gdb is linked with the simulator.
1128 * debug.c (ppc_trace): Ditto.
1129 * sim_calls.c (sim_open): Change trace -> ppc_trace.
1130 * main.c (main): Ditto.
1132 * cpu.c (cpu_add_commas): Remove extra static.
1134 Thu Oct 12 11:35:53 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1136 * Makefile.in (psim.o): Now that inlines are turned on, make
1137 psim.o depend on all sources.
1139 * cpu.c (cpu_add_commas): New function to format a long with
1141 (cpu_print_info): Use it to print number_of_insns.
1143 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
1145 (ENDIAN_N): If both target and host byte orders are known, don't
1146 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
1148 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
1149 to allow target specific H2T_n/T2H_n macros to be used.
1150 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
1151 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
1152 of the 3 instruction sequence that runs on 386s.
1154 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
1155 specified on the compile line.
1156 (WITH_BSWAP): If not defined, define as 0.
1158 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
1159 default inline support. Pass INLINE_CFLAGS when compiling.
1161 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
1162 INLINE_DEVICES since GCC doesn't like inline functions that
1163 accept variable arguments.
1164 (stack_ioctl_callback): Make function just static because GCC
1165 doesn't like inline functions that accept variable arguments.
1167 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1169 * inline.c: Correct pathnames of included C files to match current
1172 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1173 non-zero, define STATIC_DEVICES to be static.
1175 * std-config.h (INLINE): If GNU C and optimizing, define this as
1177 (DEFAULT_INLINE): If not defined, define as 0.
1178 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1179 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.

1182 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1184 * ppc-instructions: Initial cut of floating point suport added.
1185 Of note include - use of host IEEE floating point instructions,
1186 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1187 currently a pretty sight.
1189 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1190 merge into core.h, core.c, core_n.h. The type memory_map replaced
1191 with core_map. This removes a level of pointer indirection when
1192 translating an address.
1194 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1196 * Makefile.in et.al (sorry): tweek to use new core, core_map and

1201 * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to
1202 most of the other functions in sim_calls.c.
1204 * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
1205 Add macros to better cover up `generic' code. Makes it possible
1206 to step through the generic code!
1208 * vm.c, vm_n.h, Makefile.in: ditto
1210 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
1212 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1213 callback interface so that there is a read/write buffer but no
1214 read/write_word. VEA default memory read/write handler sometimes
1215 couldn't resolve an access and of those some were for a memory
1216 fault and some were because gdb was making a bogus request.
1218 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
1219 eliminate transfer_mode (raw or cooked) parameter from read/write
1222 Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>
1224 * ppc-instructions (fmul, fmuls): correct instruction format - had
1227 Wed Oct 4 17:31:12 1995 Andrew Cagney <cagney@highland.com.au>
1229 * psim.c, device_tree.h, device_tree.c, devices.c (printd_*,
1230 scand_*): new functions to parse/print fields in device names
1231 while hiding any machine dependency.
1233 * devices.c, psim.c: Change the stack init code so that it is
1234 handled by a device. Arguments passed across using a device ioctl
1237 * devices.h, devices.c: device ioctl callback changed to allow a
1238 variable number of arguments. This gives greater flexability and
1239 greater chance of bugs.
1241 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
1243 * main.c (printf_filtered, error): Missing va_end() to close off
1244 variable argument use.
1246 * Makefile.in (tmp-gencode): comment out hack to get around some
1247 versions of make not handling files being created as side-effects.
1249 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
1250 alternative file name to use in output files for things like #line
1253 Makefile.in (tmp-gencode): Use gen -n so that debug info is
1256 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the

1274 instructions issued.
1275 (cpu_print_info): New function to print cpu related information.
1276 At present, print the number of instructions executed.
1278 * gen_idecode_c: Emit call to cpu_increment_number_of_insns within
1281 * psim.c (psim_print_info): New function to iterate over each of
1282 the CPU's calling cpu_print_info.
1284 * psim.h,cpu.h: Add new declarations.
1286 * sim_calls.c (sim_open): Add argument processing to add the same
1287 switches main.c accepts for the standalone processor.
1288 (sim_close): Call psim_print_info if -I.
1290 * main.c (main): Add comment saying to update sim_calls.c when
1291 adding switches. Add -I to call psim_print_info when done.

1310 * psim.c (write_stack_arguments): Don't write any stack arguments
1313 * main.c (main): Switch to using getopt. Make -p also set
1314 trace_semantics. Make -a turn on all trace flags. Make -C turn
1317 * device_tree.c (create_option_device_node): Assume a program is
1318 OEA if the start address is < 4096, not just == 0.
1320 Wed Sep 20 13:36:06 1995 Ian Lance Taylor <ian@cygnus.com>

1364 Wed Sep 6 13:25:42 1995 Andrew Cagney <cagney@highland.com.au>
1366 * core.c (core_add_data): First growth of bss was being put at
1367 wrong address (0) instead of &end.
1369 * core.c (core_add_stack, core_add_data): Was not handling case
1370 where bss/stack is grown across the current end-of-{bss,stack}.
1372 Wed Sep 6 00:46:10 1995 Andrew Cagney <cagney@highland.com.au>
1374 * system.c (system_call): Fix SYS_break - was aligning bss to a
