643 Make the simulator compatible with the MPC750. It would be nicer
644 to make this a real multi-sim, but that's more work than we have
645 time for.
646 * emul_generic.c (emul_add_tree_options): Only require strict
647 alignment if it was explicitly requested at configuration time.
648 Don't make it the default for little-endian machines.
649 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
650 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
651 THRM2, THRM3): Plop in the MPC750 SPR registers.
652 (DABR): This is weird. This was HID5, but the PPC spec says this
653 should be DABR; why did some random processor use it for something
654 else? The HID5 entry dates back to the original checkin of the
655 simulator code in 1995, so remove it.
656 * sim_calls.c (register_names): Delete this; since the user can
657 now change GDB's list of register names dynamically, we can't
658 pretend there's a static mapping here.
659 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
660 function to get the register name. That ought to be accurate.
661 However, we're changing a compile-time dependency (using the
662 REGISTER_NAMES macro) into a link- and run-time dependency
663 (calling REGISTER_NAME, which happens to be a function call on the
664 PPC).

696Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
697
698 * table.c (table_open): For cygwin hosts, we need to use the
699 return value from the read routine as the number of bytes to
700 process. This apparently is due to text-mode vs binary-mode. If
701 the mounts are done text-mode, then the size returnedby fstat()
702 may be different than the number of bytes "read" in text mode.

1098 shift + mask + test.
1099
1100 * gen-idecode.c: Correct generated igen body so that it no drops
1101 or doubles clock interrupts.
1102

1132 * misc.c (name2i): Possibly abort if an invalid name is
1133 encountered.
1134 * ld-decode.c: Abort if the table type isn't found.

1141
1142 * psim.c (psim_write_register, psim_read_register): Force the cpu
1143 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1144 next cpu would be zero any way.

1150Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1151
1152 * The code to allow an event queue to be updated during a signal
1153 was missing. For main.c, a cntrl-c simulation termination wasn't
1154 handled cleanly.

1156 * The simulation would not correctly restart if an event requested
1157 that the simulation be halted.

1166
1167 * events.c (event_queue_process): Mask interrupts while
1168 manipulating the async event queue.

1171
1172 * events.c (event_queue_process): Mark the event queue as being in
1173 the processing state when processing has started. Adjust code
1174 so that it is tolerant of halts.
1175 (event_queue_init): Start the event queue out with processing
1176 false.
1177 (event_queue_tick): Check that processing isn't still being
1178 performed.
1179
1180 * gen-idecode.c (print_run_until_stop_body): Call
1181 event_queue_process_events to clear possibly pending events before

1190
1191 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1192 RA. Based on instruction frequency stats, expand additional
1193 instructions.
1194 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1195
1196 * ppc-opcode-stupid: Move all but the basic table in -complex into
1197 here. Update to new format.
1198
1199 * Makefile.in (tmp-defines): New target. Force defines.h to always
1200 be built. Hence get ppc-opcode-goto to build.
1201
1202Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1203

1205 Implement.
1206
1207Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1208
1209 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1210 to be initialized independant of the rest of the simulation
1211 initalization. Otherwize a trace option explictly set from gdb
1212 could be overridden by hw_trace.
1213
1214 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1215
1216 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1217 debug.c. It could be much simpler.
1218
1219Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1220
1221 * Some devices support removable media. Add hooks to the disk
1222 device so that it supports this.

1232 media. If no file image is specified, use the next one in the
1233 image property list.
1234 (hw_disk_init_address): Change the file property so that it is a
1235 string array - use the first entry for the initial file image.
1236
1237 * tree.c (print_string_aray_property): New function - print a
1238 string array.
1239 (print_properties): Adjust.

1250
1251Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1252
1253 * For expressions like (RA == 0) that are entered in to the cache
1254 as RA_is_0. If possible generate the result of the expression so
1255 that the compiler gets a better chance of eliminating dead
1256 branches.
1257
1258 * gen-icache.c (print_icache_extraction): For a cache entry of
1259 the form <name>_is_<const> where it is a boolean field, generate
1260 the result of the expression instead of the expression its self.
1261 (print_icache_body): Remove code that was looking for *_is_0 and
1262 then generating corresponding definitions.
1263
1264 * gen-icache.c (print_icache_struct): If there is no cache, do not
1265 output expressions in idecode.h file.
1266
1267 * gen-icache.c (print_icache_body): Output them here.
1268
1269 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1270 expansion.
1271

1274Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1275
1276 * The code that put values in and extracted values from the cache
1277 was too compilicated. The cache table did not allow values to be
1278 computed from cache entries. #defines could only be used when a
1279 cache was present, remove the restriction.
1280
1281 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1282 scratch variable is defined when a cache entry is beinf
1283 filled. Change the definition of a COMPUTE variable to be defined
1284 when the cache entry is being used.
1285 * gen-icache.c: Update.
1286
1287 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1288 is more obvious. old_name->field_name, new_name->derived_name.
1289 * gen-icache.c: Update
1290
1291 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1292 different types of cache code - put into cache, extract from
1293 cache, no cache - an explicit argument to print_icache_body.
1294 * gen-icache.c (print_icache_extraction): Ditto.
1295
1296 * gen-semantics.c (print_c_semantic): Update use.
1297 * gen-idecode.c (print_jump_insn): Update use.
1298 * gen-icache.c (print_icache_function): Update use.
1299

2663 possible for user packages to be specified.
2664
2665 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
2666 hardware instead of checking it using ls. configure.in should
2667 have taken care of any problems.
2668 (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
2669
2670Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
2671
2672 * psim.c (psim_options): Enter the argument to the memory size
2673 option directly into the device tree. Was using atol() which is
2674 dangerously non portable.
2675

2677
2678 * configure.in (icache): Extend icache flag to include an insn
2679 option. If specifyed the insn - aka instruction - is included in

2709
2710 * gen-idecode.c: Output the complete run_until_stop function
2711 instead of just the code to handle a single instruction issue.
2712 * : Have the generated idecode.c include inline.c (instead of psim.c).
2713
2714 * std-config.h: Change psim.c so that it isn't inlined (as this is
2715 no longer needed).
2716
2717 * psim.c (run_until_stop): Delete the old run_until_stop function
2718 instead calling the idecode_run and idecode_run_until_stop
2719 functions that gen-idecode.c is now creating.
2720
2721Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2722
2723 * dgen.c: Maintenance - update to use new features found in lf.c.

2746 corresponding call to ITRACE so that it still matches.
2747
2748 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
2749 of ITRACE. The CPP line directives would have previously set the
2750 line-nr and file name so ITRACE isn't needed.

2753
2754 * gen-idecode.c (print_jump_until_stop_body): New function and
2755 idecode generation option. Instead of generating and calling

2761
2762 * configure.in: New option --enable-sim-jump (default disabled)

2769 testing jumping idecodes.
2770

2777 decode functions.
2778
2779 * configure.in (--enable-sim-icache): Accept an option list such
2780 as 1024,define. Add a new choice to the list - semantic - which
2781 will cause igen to generate instruction decode functions that
2782 include the corresponding semantic code.
2783
2784Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2785
2786 * configure.in: New option --enable-sim-line-nr (default enabled).
2787 Enable/disable the inclusion of CPP line directives in the
2788 generated files. Such directives refer back to the source files
2789 used when generating the simulator code.
2790
2791 * Makefile.in (sim_line_nr): Pass to igen.

2801
2802 * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
2803 that they use the same technique as igen (ie a dummy targets
2804 tmp-pk and tmp-hw are created).
2805
2806Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2807
2808 * Makefile.in (BUILD_CFLAGS): Include WARNING_CFLAGS.
