624 Make the simulator compatible with the MPC750. It would be nicer
625 to make this a real multi-sim, but that's more work than we have
626 time for.
627 * emul_generic.c (emul_add_tree_options): Only require strict
628 alignment if it was explicitly requested at configuration time.
629 Don't make it the default for little-endian machines.
630 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
631 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
632 THRM2, THRM3): Plop in the MPC750 SPR registers.
633 (DABR): This is weird. This was HID5, but the PPC spec says this
634 should be DABR; why did some random processor use it for something
635 else? The HID5 entry dates back to the original checkin of the
636 simulator code in 1995, so remove it.
637 * sim_calls.c (register_names): Delete this; since the user can
638 now change GDB's list of register names dynamically, we can't
639 pretend there's a static mapping here.
640 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
641 function to get the register name. That ought to be accurate.
642 However, we're changing a compile-time dependency (using the
643 REGISTER_NAMES macro) into a link- and run-time dependency
644 (calling REGISTER_NAME, which happens to be a function call on the
645 PPC).
646
6471999-01-22 Jim Lemke <jlemke@cygnus.com>
648
649 * igen.c(gen_semantics_[ch]): setup/use of new option
650 (-o mpc860c0[=n]).

652 ppc-instructions(the four branch insn groups): detect problematic br's.
653 psim.c(is_num - added, psim_options): Parse and init new option.
654 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

669 poll the external environment.
670
6711998-11-19 Michael Meissner <meissner@cygnus.com>
672
673 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
674 fractional type, so that quiet NaN's aren't treated like
675 Infinities.
676
677Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
678
679 * table.c (table_open): For cygwin hosts, we need to use the
680 return value from the read routine as the number of bytes to
681 process. This apparently is due to text-mode vs binary-mode. If
682 the mounts are done text-mode, then the size returnedby fstat()
683 may be different than the number of bytes "read" in text mode.
684
685Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>

707
708Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
709
710 * Makefile.in: The run target depended on a target psim$(EXEEXT),
711 but there was no such target, only plain psim. So I changed the
712 run target to depend on psim.
713
714Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
715
716 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
717 now defined in ../common/aclocal.m4, and the double definition causes
718 problems with AC_SUBST of EXEEXT.

1075
1076 * gen-idecode.c: Re-work the table lookup code so that it assumes
1077 that the entry is a leaf by default. Simplify the boolean table
1078 entry code so that it involves a mask + test instead of shift +
1079 shift + mask + test.
1080
1081 * gen-idecode.c: Correct generated igen body so that it no drops
1082 or doubles clock interrupts.
1083
1084

1111 fields.
1112
1113 * misc.c (name2i): Possibly abort if an invalid name is
1114 encountered.
1115 * ld-decode.c: Abort if the table type isn't found.

1122
1123 * psim.c (psim_write_register, psim_read_register): Force the cpu
1124 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1125 next cpu would be zero any way.
1126
1127 * mon.c (mon_print_info): If possible, print the system cycle
1128 performance. This is an indication of the number of instructions
1129 per second.

1131Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1132
1133 * The code to allow an event queue to be updated during a signal
1134 was missing. For main.c, a cntrl-c simulation termination wasn't
1135 handled cleanly.
1136
1137 * The simulation would not correctly restart if an event requested
1138 that the simulation be halted.
1139

1141 include a level vis -i2.
1142 (psim_usage): Document.
1143

1145 cntrl-c occures schedule an event to halt the simulation.
1146 (main): Catch CNTRL-C signals with the function cntrl_c.
1147
1148 * events.c (event_queue_process): Mask interrupts while
1149 manipulating the async event queue.
1150 (event_queue_init): Ditto.
1151 (event_queue_schedule_after_signal): Ditto.
1152
1153 * events.c (event_queue_process): Mark the event queue as being in
1154 the processing state when processing has started. Adjust code
1155 so that it is tolerant of halts.
1156 (event_queue_init): Start the event queue out with processing
1157 false.
1158 (event_queue_tick): Check that processing isn't still being
1159 performed.
1160
1161 * gen-idecode.c (print_run_until_stop_body): Call
1162 event_queue_process_events to clear possibly pending events before

1171
1172 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1173 RA. Based on instruction frequency stats, expand additional
1174 instructions.
1175 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1176
1177 * ppc-opcode-stupid: Move all but the basic table in -complex into
1178 here. Update to new format.
1179
1180 * Makefile.in (tmp-defines): New target. Force defines.h to always
1181 be built. Hence get ppc-opcode-goto to build.
1182
1183Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1184
1185 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1186 Implement.
1187
1188Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1189
1190 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1191 to be initialized independant of the rest of the simulation
1192 initalization. Otherwize a trace option explictly set from gdb
1193 could be overridden by hw_trace.
1194
1195 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1196
1197 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1198 debug.c. It could be much simpler.
1199
1200Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1201
1202 * Some devices support removable media. Add hooks to the disk
1203 device so that it supports this.

1213 media. If no file image is specified, use the next one in the
1214 image property list.
1215 (hw_disk_init_address): Change the file property so that it is a
1216 string array - use the first entry for the initial file image.
1217
1218 * tree.c (print_string_aray_property): New function - print a
1219 string array.
1220 (print_properties): Adjust.
1221 (print_string): Write a string, handling double quotes.

1231
1232Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1233
1234 * For expressions like (RA == 0) that are entered in to the cache
1235 as RA_is_0. If possible generate the result of the expression so
1236 that the compiler gets a better chance of eliminating dead
1237 branches.
1238
1239 * gen-icache.c (print_icache_extraction): For a cache entry of
1240 the form <name>_is_<const> where it is a boolean field, generate
1241 the result of the expression instead of the expression its self.
1242 (print_icache_body): Remove code that was looking for *_is_0 and
1243 then generating corresponding definitions.
1244
1245 * gen-icache.c (print_icache_struct): If there is no cache, do not
1246 output expressions in idecode.h file.
1247
1248 * gen-icache.c (print_icache_body): Output them here.
1249
1250 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1251 expansion.
1252

1254
1255Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1256
1257 * The code that put values in and extracted values from the cache
1258 was too compilicated. The cache table did not allow values to be
1259 computed from cache entries. #defines could only be used when a
1260 cache was present, remove the restriction.
1261
1262 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1263 scratch variable is defined when a cache entry is beinf
1264 filled. Change the definition of a COMPUTE variable to be defined
1265 when the cache entry is being used.
1266 * gen-icache.c: Update.
1267
1268 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1269 is more obvious. old_name->field_name, new_name->derived_name.
1270 * gen-icache.c: Update
1271
1272 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1273 different types of cache code - put into cache, extract from
1274 cache, no cache - an explicit argument to print_icache_body.
1275 * gen-icache.c (print_icache_extraction): Ditto.
1276
1277 * gen-semantics.c (print_c_semantic): Update use.
1278 * gen-idecode.c (print_jump_insn): Update use.
1279 * gen-icache.c (print_icache_function): Update use.
1280
1281 * igen.c (main): Change 'R' option so that it does not force the
1282 cache.
1283
1284 * configure.in (enable-sim-icache): Clarify description. Make
1285 #define one of the defaults regardless of the cache. Probably
1286 should revamp and add a separate option.
1287
1288Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1289

2646 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
2647 hardware instead of checking it using ls. configure.in should
2648 have taken care of any problems.

2650
2651Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
2652
2653 * psim.c (psim_options): Enter the argument to the memory size
2654 option directly into the device tree. Was using atol() which is
2655 dangerously non portable.
2656

2690
2691 * gen-idecode.c: Output the complete run_until_stop function
2692 instead of just the code to handle a single instruction issue.
2693 * : Have the generated idecode.c include inline.c (instead of psim.c).
2694
2695 * std-config.h: Change psim.c so that it isn't inlined (as this is
2696 no longer needed).
2697
2698 * psim.c (run_until_stop): Delete the old run_until_stop function
2699 instead calling the idecode_run and idecode_run_until_stop
2700 functions that gen-idecode.c is now creating.

2727 corresponding call to ITRACE so that it still matches.
2728
2729 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead

2734
2735 * gen-idecode.c (print_jump_until_stop_body): New function and
2736 idecode generation option. Instead of generating and calling

2742
2743 * configure.in: New option --enable-sim-jump (default disabled)

2759
2760 * configure.in (--enable-sim-icache): Accept an option list such
2761 as 1024,define. Add a new choice to the list - semantic - which
2762 will cause igen to generate instruction decode functions that
2763 include the corresponding semantic code.

2765Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2766
2767 * configure.in: New option --enable-sim-line-nr (default enabled).
