628 Make the simulator compatible with the MPC750. It would be nicer
629 to make this a real multi-sim, but that's more work than we have
630 time for.
631 * emul_generic.c (emul_add_tree_options): Only require strict
632 alignment if it was explicitly requested at configuration time.
633 Don't make it the default for little-endian machines.
634 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
635 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
636 THRM2, THRM3): Plop in the MPC750 SPR registers.
637 (DABR): This is weird. This was HID5, but the PPC spec says this
638 should be DABR; why did some random processor use it for something
639 else? The HID5 entry dates back to the original checkin of the
640 simulator code in 1995, so remove it.
641 * sim_calls.c (register_names): Delete this; since the user can
642 now change GDB's list of register names dynamically, we can't
643 pretend there's a static mapping here.
644 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
645 function to get the register name. That ought to be accurate.
646 However, we're changing a compile-time dependency (using the
647 REGISTER_NAMES macro) into a link- and run-time dependency
648 (calling REGISTER_NAME, which happens to be a function call on the
649 PPC).
650
6511999-01-22 Jim Lemke <jlemke@cygnus.com>
652
653 * igen.c(gen_semantics_[ch]): setup/use of new option

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

6751998-11-19 Michael Meissner <meissner@cygnus.com>
676
677 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
678 fractional type, so that quiet NaN's aren't treated like
679 Infinities.
680
681Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
682
683 * table.c (table_open): For cygwin hosts, we need to use the
684 return value from the read routine as the number of bytes to
685 process. This apparently is due to text-mode vs binary-mode. If
686 the mounts are done text-mode, then the size returnedby fstat()
687 may be different than the number of bytes "read" in text mode.

712Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
713
714 * Makefile.in: The run target depended on a target psim$(EXEEXT),
715 but there was no such target, only plain psim. So I changed the
716 run target to depend on psim.
717
718Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
719
720 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
721 now defined in ../common/aclocal.m4, and the double definition causes
722 problems with AC_SUBST of EXEEXT.

1079
1080 * gen-idecode.c: Re-work the table lookup code so that it assumes
1081 that the entry is a leaf by default. Simplify the boolean table
1082 entry code so that it involves a mask + test instead of shift +
1083 shift + mask + test.
1084
1085 * gen-idecode.c: Correct generated igen body so that it no drops
1086 or doubles clock interrupts.
1087

1117 * misc.c (name2i): Possibly abort if an invalid name is
1118 encountered.
1119 * ld-decode.c: Abort if the table type isn't found.

1126
1127 * psim.c (psim_write_register, psim_read_register): Force the cpu
1128 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1129 next cpu would be zero any way.
1130
1131 * mon.c (mon_print_info): If possible, print the system cycle
1132 performance. This is an indication of the number of instructions
1133 per second.

1135Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1136
1137 * The code to allow an event queue to be updated during a signal
1138 was missing. For main.c, a cntrl-c simulation termination wasn't
1139 handled cleanly.
1140
1141 * The simulation would not correctly restart if an event requested
1142 that the simulation be halted.
1143

1145 include a level vis -i2.
1146 (psim_usage): Document.
1147

1149 cntrl-c occures schedule an event to halt the simulation.
1150 (main): Catch CNTRL-C signals with the function cntrl_c.
1151
1152 * events.c (event_queue_process): Mask interrupts while
1153 manipulating the async event queue.
1154 (event_queue_init): Ditto.
1155 (event_queue_schedule_after_signal): Ditto.
1156
1157 * events.c (event_queue_process): Mark the event queue as being in
1158 the processing state when processing has started. Adjust code
1159 so that it is tolerant of halts.
1160 (event_queue_init): Start the event queue out with processing
1161 false.
1162 (event_queue_tick): Check that processing isn't still being
1163 performed.
1164
1165 * gen-idecode.c (print_run_until_stop_body): Call
1166 event_queue_process_events to clear possibly pending events before

1175
1176 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1177 RA. Based on instruction frequency stats, expand additional
1178 instructions.
1179 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1180
1181 * ppc-opcode-stupid: Move all but the basic table in -complex into
1182 here. Update to new format.
1183
1184 * Makefile.in (tmp-defines): New target. Force defines.h to always
1185 be built. Hence get ppc-opcode-goto to build.
1186
1187Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1188
1189 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1190 Implement.
1191
1192Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1193
1194 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1195 to be initialized independant of the rest of the simulation
1196 initalization. Otherwize a trace option explictly set from gdb
1197 could be overridden by hw_trace.
1198
1199 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1200
1201 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1202 debug.c. It could be much simpler.
1203
1204Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1205
1206 * Some devices support removable media. Add hooks to the disk
1207 device so that it supports this.

1217 media. If no file image is specified, use the next one in the
1218 image property list.
1219 (hw_disk_init_address): Change the file property so that it is a
1220 string array - use the first entry for the initial file image.
1221
1222 * tree.c (print_string_aray_property): New function - print a
1223 string array.
1224 (print_properties): Adjust.
1225 (print_string): Write a string, handling double quotes.

1235
1236Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1237
1238 * For expressions like (RA == 0) that are entered in to the cache
1239 as RA_is_0. If possible generate the result of the expression so
1240 that the compiler gets a better chance of eliminating dead
1241 branches.
1242
1243 * gen-icache.c (print_icache_extraction): For a cache entry of
1244 the form <name>_is_<const> where it is a boolean field, generate
1245 the result of the expression instead of the expression its self.
1246 (print_icache_body): Remove code that was looking for *_is_0 and
1247 then generating corresponding definitions.
1248
1249 * gen-icache.c (print_icache_struct): If there is no cache, do not
1250 output expressions in idecode.h file.
1251
1252 * gen-icache.c (print_icache_body): Output them here.
1253
1254 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1255 expansion.
1256

1258
1259Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1260
1261 * The code that put values in and extracted values from the cache
1262 was too compilicated. The cache table did not allow values to be
1263 computed from cache entries. #defines could only be used when a
1264 cache was present, remove the restriction.
1265
1266 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1267 scratch variable is defined when a cache entry is beinf
1268 filled. Change the definition of a COMPUTE variable to be defined
1269 when the cache entry is being used.
1270 * gen-icache.c: Update.
1271
1272 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1273 is more obvious. old_name->field_name, new_name->derived_name.
1274 * gen-icache.c: Update
1275
1276 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1277 different types of cache code - put into cache, extract from
1278 cache, no cache - an explicit argument to print_icache_body.
1279 * gen-icache.c (print_icache_extraction): Ditto.
1280
1281 * gen-semantics.c (print_c_semantic): Update use.
1282 * gen-idecode.c (print_jump_insn): Update use.
1283 * gen-icache.c (print_icache_function): Update use.
1284
1285 * igen.c (main): Change 'R' option so that it does not force the
1286 cache.
1287
1288 * configure.in (enable-sim-icache): Clarify description. Make
1289 #define one of the defaults regardless of the cache. Probably
1290 should revamp and add a separate option.
1291
1292Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1293

1295 partition numbering.
1296 (pk_disklabel_create_instance): Partition 1..4 are valid - not
1297 1..3.
1298 (is_iso9660): New function, verify a CD9660 File system.

2648 possible for user packages to be specified.
2649
2650 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
2651 hardware instead of checking it using ls. configure.in should
2652 have taken care of any problems.

2654
2655Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
2656
2657 * psim.c (psim_options): Enter the argument to the memory size
2658 option directly into the device tree. Was using atol() which is
2659 dangerously non portable.
2660
2661Mon Jul 22 22:17:08 1996 Andrew Cagney <cagney@highland.com.au>
2662
2663 * configure.in (icache): Extend icache flag to include an insn
2664 option. If specifyed the insn - aka instruction - is included in
2665 the instruction cache. Make this the default.
2666 * configure: re-generate.
2667
2668 * igen.c (main), igen.h: Add option -S - inSn - for specifying

2682 * emul_generic.c (emul_add_tree_options): Was incorrectly setting
2683 the strict-alignment option when hardwired for non-strict
2684 alignment.
2685
2686Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2687

2694
2695 * gen-idecode.c: Output the complete run_until_stop function
2696 instead of just the code to handle a single instruction issue.
2697 * : Have the generated idecode.c include inline.c (instead of psim.c).
2698
2699 * std-config.h: Change psim.c so that it isn't inlined (as this is
2700 no longer needed).
2701
2702 * psim.c (run_until_stop): Delete the old run_until_stop function
2703 instead calling the idecode_run and idecode_run_until_stop
2704 functions that gen-idecode.c is now creating.
2705
2706Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2707

2731 corresponding call to ITRACE so that it still matches.
2732
2733 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead

2738
2739 * gen-idecode.c (print_jump_until_stop_body): New function and
2740 idecode generation option. Instead of generating and calling

2743 indirect jump) to move between code blocks.
2744
2745 * Makefile.in: Add sim_jump flag to those passed to igen.
2746
2747 * configure.in: New option --enable-sim-jump (default disabled)
2748

2754 testing jumping idecodes.
2755

2762 decode functions.
2763
2764 * configure.in (--enable-sim-icache): Accept an option list such
2765 as 1024,define. Add a new choice to the list - semantic - which
2766 will cause igen to generate instruction decode functions that
2767 include the corresponding semantic code.
2768
2769Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2770
2771 * configure.in: New option --enable-sim-line-nr (default enabled).
2772 Enable/disable the inclusion of CPP line directives in the
2773 generated files. Such directives refer back to the source files
2774 used when generating the simulator code.
2775
2776 * Makefile.in (sim_line_nr): Pass to igen.
2777
2778Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

2790
2791Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2792
2793 * Makefile.in (BUILD_CFLAGS): Include WARNING_CFLAGS.
