720 Make the simulator compatible with the MPC750. It would be nicer
721 to make this a real multi-sim, but that's more work than we have
722 time for.
723 * emul_generic.c (emul_add_tree_options): Only require strict
724 alignment if it was explicitly requested at configuration time.
725 Don't make it the default for little-endian machines.
726 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
727 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
728 THRM2, THRM3): Plop in the MPC750 SPR registers.
729 (DABR): This is weird. This was HID5, but the PPC spec says this
730 should be DABR; why did some random processor use it for something
731 else? The HID5 entry dates back to the original checkin of the
732 simulator code in 1995, so remove it.
733 * sim_calls.c (register_names): Delete this; since the user can
734 now change GDB's list of register names dynamically, we can't
735 pretend there's a static mapping here.
736 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
737 function to get the register name. That ought to be accurate.
738 However, we're changing a compile-time dependency (using the
739 REGISTER_NAMES macro) into a link- and run-time dependency
740 (calling REGISTER_NAME, which happens to be a function call on the
741 PPC).

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

812 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are

1175 shift + mask + test.
1176

1228
1229 * The code to allow an event queue to be updated during a signal

1252 (event_queue_init): Start the event queue out with processing
1253 false.
1254 (event_queue_tick): Check that processing isn't still being
1255 performed.

1285
1286 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1287 to be initialized independant of the rest of the simulation
1288 initalization. Otherwize a trace option explictly set from gdb
1289 could be overridden by hw_trace.
1290

1399 capibility is only used during the lifetime of the corresponding
1400 object.
1401
1402 * cap.h, cap.c: Correct cap type - was signed32 should be
1403 signed_cell.

2660
2661 * std-config.h (SEMANTICS_INLINE): By default, mask out the
2662 inlining of semantic functions from DEFAULT_INLINE. Almost all
2663 configurations call the semantic code via a pointer so there is
2664 little benefit.

2667
2668Thu Jul 25 20:07:30 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

2694 always update the cache_entries semantic and address fields.
2695
2696 * gen-idecode.c (print_idecode_switch_illegal): Include a break
2697 when generating illegal instructions. This was commented out
2698 which is a hangover from looking a at switch statements generated
2699 using indirect jumps.
2700
2701Tue Jul 23 20:57:01 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

2710 support.h so that, like cpu, it is optionally inlined for all
2711 modules that include it.
2712 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2713 same as cpu.[hc].
2714
2715 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2716 name for a lable and then branch to it.
2717
2718 * ppc-instructions (convert_to_integer, Floating Round to
2719 Single-Precision, Floating Convert from Integer Doubleword): Use
2720 LABEL and GOTO instead of the recently added switch statements.
2721
2722Wed Jul 24 14:02:42 1996 Andrew Cagney <cagney@sawnoff.highland.com.au>
2723
2724 * gen-idecode.c (print_run_until_stop_body): Too many rparen in

2742 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
2743 hardware instead of checking it using ls. configure.in should
2744 have taken care of any problems.
2745 (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
2746
2747Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
2748
2749 * psim.c (psim_options): Enter the argument to the memory size
2750 option directly into the device tree. Was using atol() which is

2771
2772Mon Jul 22 20:00:25 1996 Andrew Cagney <cagney@highland.com.au>
2773
2774 * emul_generic.c (emul_add_tree_options): Was incorrectly setting
2775 the strict-alignment option when hardwired for non-strict
2776 alignment.
2777
2778Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2779
2780 * gen-semantics.c: Make the my_index variable a macro MY_INDEX.

2786
2787 * gen-idecode.c: Output the complete run_until_stop function
2788 instead of just the code to handle a single instruction issue.
2789 * : Have the generated idecode.c include inline.c (instead of psim.c).
2790
2791 * std-config.h: Change psim.c so that it isn't inlined (as this is
2792 no longer needed).
2793
2794 * psim.c (run_until_stop): Delete the old run_until_stop function
2795 instead calling the idecode_run and idecode_run_until_stop
2796 functions that gen-idecode.c is now creating.
2797
2798Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2799
2800 * dgen.c: Maintenance - update to use new features found in lf.c.

2823 corresponding call to ITRACE so that it still matches.
2824
2825 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead

2830
2831 * gen-idecode.c (print_jump_until_stop_body): New function and
2832 idecode generation option. Instead of generating and calling

2846 testing jumping idecodes.
2847

2854 decode functions.
2855
2856 * configure.in (--enable-sim-icache): Accept an option list such
2857 as 1024,define. Add a new choice to the list - semantic - which
2858 will cause igen to generate instruction decode functions that
2859 include the corresponding semantic code.
2860
2861Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2862
2863 * configure.in: New option --enable-sim-line-nr (default enabled).
2864 Enable/disable the inclusion of CPP line directives in the
2865 generated files. Such directives refer back to the source files
2866 used when generating the simulator code.

2879 * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
2880 that they use the same technique as igen (ie a dummy targets
2881 tmp-pk and tmp-hw are created).
2882
2883Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2884
2885 * Makefile.in (BUILD_CFLAGS): Include WARNING_CFLAGS.

2995 core object.
2996
