717 Make the simulator compatible with the MPC750. It would be nicer
718 to make this a real multi-sim, but that's more work than we have
719 time for.
720 * emul_generic.c (emul_add_tree_options): Only require strict
721 alignment if it was explicitly requested at configuration time.
722 Don't make it the default for little-endian machines.

724 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
725 THRM2, THRM3): Plop in the MPC750 SPR registers.
726 (DABR): This is weird. This was HID5, but the PPC spec says this
727 should be DABR; why did some random processor use it for something
728 else? The HID5 entry dates back to the original checkin of the
729 simulator code in 1995, so remove it.
730 * sim_calls.c (register_names): Delete this; since the user can
731 now change GDB's list of register names dynamically, we can't
732 pretend there's a static mapping here.
733 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
734 function to get the register name. That ought to be accurate.
735 However, we're changing a compile-time dependency (using the
736 REGISTER_NAMES macro) into a link- and run-time dependency
737 (calling REGISTER_NAME, which happens to be a function call on the
738 PPC).

772 * table.c (table_open): For cygwin hosts, we need to use the
773 return value from the read routine as the number of bytes to
774 process. This apparently is due to text-mode vs binary-mode. If
775 the mounts are done text-mode, then the size returnedby fstat()
776 may be different than the number of bytes "read" in text mode.

1172 shift + mask + test.
1173
1174 * gen-idecode.c: Correct generated igen body so that it no drops
1175 or doubles clock interrupts.

1215
1216 * psim.c (psim_write_register, psim_read_register): Force the cpu
1217 to zero when it is either of `-1' or `nr_cpus'. In both cases the

1221 performance. This is an indication of the number of instructions
1222 per second.

1224Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1225
1226 * The code to allow an event queue to be updated during a signal
1227 was missing. For main.c, a cntrl-c simulation termination wasn't
1228 handled cleanly.
1229
1230 * The simulation would not correctly restart if an event requested
1231 that the simulation be halted.

1247 the processing state when processing has started. Adjust code
1248 so that it is tolerant of halts.
1249 (event_queue_init): Start the event queue out with processing
1250 false.
1251 (event_queue_tick): Check that processing isn't still being
1252 performed.
1253
1254 * gen-idecode.c (print_run_until_stop_body): Call
1255 event_queue_process_events to clear possibly pending events before

1264
1265 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1266 RA. Based on instruction frequency stats, expand additional
1267 instructions.
1268 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1269
1270 * ppc-opcode-stupid: Move all but the basic table in -complex into
1271 here. Update to new format.
1272
1273 * Makefile.in (tmp-defines): New target. Force defines.h to always
1274 be built. Hence get ppc-opcode-goto to build.
1275

1279 Implement.
1280
1281Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1282
1283 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1284 to be initialized independant of the rest of the simulation
1285 initalization. Otherwize a trace option explictly set from gdb
1286 could be overridden by hw_trace.
1287
1288 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1289
1290 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1291 debug.c. It could be much simpler.

1396 capibility is only used during the lifetime of the corresponding
1397 object.
1398

2657
2658 * std-config.h (SEMANTICS_INLINE): By default, mask out the
2659 inlining of semantic functions from DEFAULT_INLINE. Almost all
2660 configurations call the semantic code via a pointer so there is
2661 little benefit.
2662

2691 always update the cache_entries semantic and address fields.
2692
2693 * gen-idecode.c (print_idecode_switch_illegal): Include a break
2694 when generating illegal instructions. This was commented out
2695 which is a hangover from looking a at switch statements generated
2696 using indirect jumps.
2697
2698Tue Jul 23 20:57:01 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

2707 support.h so that, like cpu, it is optionally inlined for all
2708 modules that include it.
2709 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2710 same as cpu.[hc].
2711
2712 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2713 name for a lable and then branch to it.
2714
2715 * ppc-instructions (convert_to_integer, Floating Round to
2716 Single-Precision, Floating Convert from Integer Doubleword): Use
2717 LABEL and GOTO instead of the recently added switch statements.
2718
2719Wed Jul 24 14:02:42 1996 Andrew Cagney <cagney@sawnoff.highland.com.au>
2720
2721 * gen-idecode.c (print_run_until_stop_body): Too many rparen in

2739 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
2740 hardware instead of checking it using ls. configure.in should
2741 have taken care of any problems.
2742 (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
2743
2744Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
2745
2746 * psim.c (psim_options): Enter the argument to the memory size
2747 option directly into the device tree. Was using atol() which is
2748 dangerously non portable.
2749

2768
2769Mon Jul 22 20:00:25 1996 Andrew Cagney <cagney@highland.com.au>
2770
2771 * emul_generic.c (emul_add_tree_options): Was incorrectly setting
2772 the strict-alignment option when hardwired for non-strict
2773 alignment.
2774
2775Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2776
2777 * gen-semantics.c: Make the my_index variable a macro MY_INDEX.

2783
2784 * gen-idecode.c: Output the complete run_until_stop function
2785 instead of just the code to handle a single instruction issue.
2786 * : Have the generated idecode.c include inline.c (instead of psim.c).
2787
2788 * std-config.h: Change psim.c so that it isn't inlined (as this is
2789 no longer needed).
2790
2791 * psim.c (run_until_stop): Delete the old run_until_stop function
2792 instead calling the idecode_run and idecode_run_until_stop
2793 functions that gen-idecode.c is now creating.
2794
2795Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2796
2797 * dgen.c: Maintenance - update to use new features found in lf.c.

2820 corresponding call to ITRACE so that it still matches.
2821
2822 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead

2827
2828 * gen-idecode.c (print_jump_until_stop_body): New function and
2829 idecode generation option. Instead of generating and calling

2843 testing jumping idecodes.
2844

2851 decode functions.
2852
2853 * configure.in (--enable-sim-icache): Accept an option list such
2854 as 1024,define. Add a new choice to the list - semantic - which
2855 will cause igen to generate instruction decode functions that
2856 include the corresponding semantic code.
2857
2858Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2859
2860 * configure.in: New option --enable-sim-line-nr (default enabled).
2861 Enable/disable the inclusion of CPP line directives in the
2862 generated files. Such directives refer back to the source files
2863 used when generating the simulator code.

2876 * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
2877 that they use the same technique as igen (ie a dummy targets
2878 tmp-pk and tmp-hw are created).
2879
2880Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2881
2882 * Makefile.in (BUILD_CFLAGS): Include WARNING_CFLAGS.

2992 core object.
2993
