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

711Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
712
713 * table.c (table_open): For cygwin hosts, we need to use the
714 return value from the read routine as the number of bytes to
715 process. This apparently is due to text-mode vs binary-mode. If
716 the mounts are done text-mode, then the size returnedby fstat()
717 may be different than the number of bytes "read" in text mode.

1113 shift + mask + test.
1114
1115 * gen-idecode.c: Correct generated igen body so that it no drops
1116 or doubles clock interrupts.
1117

1148 encountered.
1149 * ld-decode.c: Abort if the table type isn't found.

1156
1157 * psim.c (psim_write_register, psim_read_register): Force the cpu
1158 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1159 next cpu would be zero any way.

1166
1167 * The code to allow an event queue to be updated during a signal
1168 was missing. For main.c, a cntrl-c simulation termination wasn't

1188 the processing state when processing has started. Adjust code
1189 so that it is tolerant of halts.
1190 (event_queue_init): Start the event queue out with processing
1191 false.
1192 (event_queue_tick): Check that processing isn't still being
1193 performed.

1205
1206 * ppc-opcode-complex: Correct typo - was expanding ORA instead of

1208 instructions.
1209 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1210
1211 * ppc-opcode-stupid: Move all but the basic table in -complex into
1212 here. Update to new format.
1213
1214 * Makefile.in (tmp-defines): New target. Force defines.h to always
1215 be built. Hence get ppc-opcode-goto to build.
1216
1217Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1218

1220 Implement.
1221
1222Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1223
1224 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1225 to be initialized independant of the rest of the simulation
1226 initalization. Otherwize a trace option explictly set from gdb
1227 could be overridden by hw_trace.
1228
1229 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1230
1231 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1232 debug.c. It could be much simpler.
1233
1234Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1235
1236 * Some devices support removable media. Add hooks to the disk

1247 media. If no file image is specified, use the next one in the
1248 image property list.
1249 (hw_disk_init_address): Change the file property so that it is a
1250 string array - use the first entry for the initial file image.
1251
1252 * tree.c (print_string_aray_property): New function - print a
1253 string array.
1254 (print_properties): Adjust.

1267
1268 * For expressions like (RA == 0) that are entered in to the cache
1269 as RA_is_0. If possible generate the result of the expression so
1270 that the compiler gets a better chance of eliminating dead
1271 branches.
1272
1273 * gen-icache.c (print_icache_extraction): For a cache entry of
1274 the form <name>_is_<const> where it is a boolean field, generate
1275 the result of the expression instead of the expression its self.
1276 (print_icache_body): Remove code that was looking for *_is_0 and
1277 then generating corresponding definitions.
1278
1279 * gen-icache.c (print_icache_struct): If there is no cache, do not
1280 output expressions in idecode.h file.
1281
1282 * gen-icache.c (print_icache_body): Output them here.
1283
1284 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1285 expansion.

1289Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1290
1291 * The code that put values in and extracted values from the cache
1292 was too compilicated. The cache table did not allow values to be
1293 computed from cache entries. #defines could only be used when a
1294 cache was present, remove the restriction.
1295
1296 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A

2650 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2651 same as cpu.[hc].
2652
2653 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2654 name for a lable and then branch to it.
2655
2656 * ppc-instructions (convert_to_integer, Floating Round to
2657 Single-Precision, Floating Convert from Integer Doubleword): Use
2658 LABEL and GOTO instead of the recently added switch statements.

2681 hardware instead of checking it using ls. configure.in should
2682 have taken care of any problems.
2683 (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
2684
2685Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
2686
2687 * psim.c (psim_options): Enter the argument to the memory size
2688 option directly into the device tree. Was using atol() which is

2715
2716Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2717
2718 * gen-semantics.c: Make the my_index variable a macro MY_INDEX.

2724
2725 * gen-idecode.c: Output the complete run_until_stop function
2726 instead of just the code to handle a single instruction issue.
2727 * : Have the generated idecode.c include inline.c (instead of psim.c).
2728
2729 * std-config.h: Change psim.c so that it isn't inlined (as this is
2730 no longer needed).
2731
2732 * psim.c (run_until_stop): Delete the old run_until_stop function
2733 instead calling the idecode_run and idecode_run_until_stop
2734 functions that gen-idecode.c is now creating.
2735
2736Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

2761 corresponding call to ITRACE so that it still matches.
2762
2763 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
2764 of ITRACE. The CPP line directives would have previously set the
2765 line-nr and file name so ITRACE isn't needed.

2768
2769 * gen-idecode.c (print_jump_until_stop_body): New function and
2770 idecode generation option. Instead of generating and calling

2784 testing jumping idecodes.
2785

2792 decode functions.
2793
2794 * configure.in (--enable-sim-icache): Accept an option list such
2795 as 1024,define. Add a new choice to the list - semantic - which
2796 will cause igen to generate instruction decode functions that
2797 include the corresponding semantic code.
2798
2799Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2800
2801 * configure.in: New option --enable-sim-line-nr (default enabled).
2802 Enable/disable the inclusion of CPP line directives in the
2803 generated files. Such directives refer back to the source files
2804 used when generating the simulator code.
2805
2806 * Makefile.in (sim_line_nr): Pass to igen.

2817 * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
2818 that they use the same technique as igen (ie a dummy targets
2819 tmp-pk and tmp-hw are created).
2820
2821Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2822
2823 * Makefile.in (BUILD_CFLAGS): Include WARNING_CFLAGS.
