600 Make the simulator compatible with the MPC750. It would be nicer
601 to make this a real multi-sim, but that's more work than we have
602 time for.
603 * emul_generic.c (emul_add_tree_options): Only require strict
604 alignment if it was explicitly requested at configuration time.
605 Don't make it the default for little-endian machines.
606 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
607 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
608 THRM2, THRM3): Plop in the MPC750 SPR registers.
609 (DABR): This is weird. This was HID5, but the PPC spec says this
610 should be DABR; why did some random processor use it for something
611 else? The HID5 entry dates back to the original checkin of the
612 simulator code in 1995, so remove it.
613 * sim_calls.c (register_names): Delete this; since the user can
614 now change GDB's list of register names dynamically, we can't
615 pretend there's a static mapping here.
616 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
617 function to get the register name. That ought to be accurate.
618 However, we're changing a compile-time dependency (using the
619 REGISTER_NAMES macro) into a link- and run-time dependency
620 (calling REGISTER_NAME, which happens to be a function call on the
621 PPC).
622

651 Infinities.
652
653Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
654
655 * table.c (table_open): For cygwin hosts, we need to use the
656 return value from the read routine as the number of bytes to
657 process. This apparently is due to text-mode vs binary-mode. If
658 the mounts are done text-mode, then the size returnedby fstat()
659 may be different than the number of bytes "read" in text mode.

686 * Makefile.in: The run target depended on a target psim$(EXEEXT),
687 but there was no such target, only plain psim. So I changed the
688 run target to depend on psim.
689
690Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
691
692 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
693 now defined in ../common/aclocal.m4, and the double definition causes

1054 entry code so that it involves a mask + test instead of shift +
1055 shift + mask + test.
1056
1057 * gen-idecode.c: Correct generated igen body so that it no drops
1058 or doubles clock interrupts.
1059

1098
1099 * psim.c (psim_write_register, psim_read_register): Force the cpu
1100 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1101 next cpu would be zero any way.

1103 * mon.c (mon_print_info): If possible, print the system cycle
1104 performance. This is an indication of the number of instructions
1105 per second.
1106
1107Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1108
1109 * The code to allow an event queue to be updated during a signal
1110 was missing. For main.c, a cntrl-c simulation termination wasn't
1111 handled cleanly.
1112
1113 * The simulation would not correctly restart if an event requested
1114 that the simulation be halted.
1115
1116 * psim.c (psim_options): Add hack to -i option to optionally
1117 include a level vis -i2.
1118 (psim_usage): Document.
1119
1120 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
1121 cntrl-c occures schedule an event to halt the simulation.
1122 (main): Catch CNTRL-C signals with the function cntrl_c.
1123
1124 * events.c (event_queue_process): Mask interrupts while

1130 the processing state when processing has started. Adjust code
1131 so that it is tolerant of halts.
1132 (event_queue_init): Start the event queue out with processing
1133 false.
1134 (event_queue_tick): Check that processing isn't still being
1135 performed.
1136
1137 * gen-idecode.c (print_run_until_stop_body): Call
1138 event_queue_process_events to clear possibly pending events before

1147
1148 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1149 RA. Based on instruction frequency stats, expand additional
1150 instructions.
1151 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1152
1153 * ppc-opcode-stupid: Move all but the basic table in -complex into
1154 here. Update to new format.
1155
1156 * Makefile.in (tmp-defines): New target. Force defines.h to always
1157 be built. Hence get ppc-opcode-goto to build.
1158
1159Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1160
1161 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1162 Implement.
1163
1164Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1165
1166 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1167 to be initialized independant of the rest of the simulation
1168 initalization. Otherwize a trace option explictly set from gdb
1169 could be overridden by hw_trace.
1170
1171 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1172
1173 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1174 debug.c. It could be much simpler.
1175
1176Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1177
1178 * Some devices support removable media. Add hooks to the disk

1189 media. If no file image is specified, use the next one in the
1190 image property list.
1191 (hw_disk_init_address): Change the file property so that it is a
1192 string array - use the first entry for the initial file image.
1193
1194 * tree.c (print_string_aray_property): New function - print a
1195 string array.
1196 (print_properties): Adjust.

1207
1208Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1209
1210 * For expressions like (RA == 0) that are entered in to the cache
1211 as RA_is_0. If possible generate the result of the expression so
1212 that the compiler gets a better chance of eliminating dead
1213 branches.
1214
1215 * gen-icache.c (print_icache_extraction): For a cache entry of
1216 the form <name>_is_<const> where it is a boolean field, generate
1217 the result of the expression instead of the expression its self.
1218 (print_icache_body): Remove code that was looking for *_is_0 and
1219 then generating corresponding definitions.
1220
1221 * gen-icache.c (print_icache_struct): If there is no cache, do not
1222 output expressions in idecode.h file.
1223
1224 * gen-icache.c (print_icache_body): Output them here.
1225
1226 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1227 expansion.

1231Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1232
1233 * The code that put values in and extracted values from the cache
1234 was too compilicated. The cache table did not allow values to be
1235 computed from cache entries. #defines could only be used when a
1236 cache was present, remove the restriction.
1237
1238 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1239 scratch variable is defined when a cache entry is beinf
1240 filled. Change the definition of a COMPUTE variable to be defined
1241 when the cache entry is being used.
1242 * gen-icache.c: Update.
1243
1244 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1245 is more obvious. old_name->field_name, new_name->derived_name.
1246 * gen-icache.c: Update
1247
1248 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1249 different types of cache code - put into cache, extract from
1250 cache, no cache - an explicit argument to print_icache_body.
1251 * gen-icache.c (print_icache_extraction): Ditto.
1252
1253 * gen-semantics.c (print_c_semantic): Update use.
1254 * gen-idecode.c (print_jump_insn): Update use.
1255 * gen-icache.c (print_icache_function): Update use.
1256
1257 * igen.c (main): Change 'R' option so that it does not force the
1258 cache.
1259
1260 * configure.in (enable-sim-icache): Clarify description. Make
1261 #define one of the defaults regardless of the cache. Probably
1262 should revamp and add a separate option.
1263
1264Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1265

1274Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1275
1276 * The cap object was retaining a reference to the instance of a
1277 device after it was deleted. Instead add and remove cap's from the
1278 cap db as they are created and deleted. This ensuring that a
1279 capibility is only used during the lifetime of the corresponding
1280 object.
1281
1282 * cap.h, cap.c: Correct cap type - was signed32 should be
1283 signed_cell.
1284
1285 * cap.c (cap_add, cap_remove): New methods for cap object that
1286 allow the explicit addition and removal of internal objects that
1287 the cap knows about.
1288
1289 * cap.c (cap_init): Rewrite. Verify that the only objects
1290 remaining in the cap data base are those that were entered first.
1291 Thse objects will be the permenant ones.
