483 to make this a real multi-sim, but that's more work than we have
485 * emul_generic.c (emul_add_tree_options): Only require strict
486 alignment if it was explicitly requested at configuration time.
487 Don't make it the default for little-endian machines.
488 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
489 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
490 THRM2, THRM3): Plop in the MPC750 SPR registers.
491 (DABR): This is weird. This was HID5, but the PPC spec says this
492 should be DABR; why did some random processor use it for something
493 else? The HID5 entry dates back to the original checkin of the
494 simulator code in 1995, so remove it.
495 * sim_calls.c (register_names): Delete this; since the user can
496 now change GDB's list of register names dynamically, we can't
497 pretend there's a static mapping here.
498 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
499 function to get the register name. That ought to be accurate.
500 However, we're changing a compile-time dependency (using the
501 REGISTER_NAMES macro) into a link- and run-time dependency
502 (calling REGISTER_NAME, which happens to be a function call on the

511 psim.c(is_num - added, psim_options): Parse and init new option.
512 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
514 1998-12-01 Ken Raeburn <raeburn@cygnus.com>

535 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
537 * table.c (table_open): For cygwin hosts, we need to use the
538 return value from the read routine as the number of bytes to
539 process. This apparently is due to text-mode vs binary-mode. If
540 the mounts are done text-mode, then the size returnedby fstat()
541 may be different than the number of bytes "read" in text mode.
543 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>

566 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
568 * Makefile.in: The run target depended on a target psim$(EXEEXT),
569 but there was no such target, only plain psim. So I changed the
570 run target to depend on psim.
572 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
574 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are

983 next cpu would be zero any way.
985 * mon.c (mon_print_info): If possible, print the system cycle
986 performance. This is an indication of the number of instructions
989 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
991 * The code to allow an event queue to be updated during a signal

1019 * gen-idecode.c (print_run_until_stop_body): Call
1020 event_queue_process_events to clear possibly pending events before

1048 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1049 to be initialized independant of the rest of the simulation
1050 initalization. Otherwize a trace option explictly set from gdb
1051 could be overridden by hw_trace.
1053 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1055 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,

1116 was too compilicated. The cache table did not allow values to be
1117 computed from cache entries. #defines could only be used when a
1118 cache was present, remove the restriction.
1120 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1121 scratch variable is defined when a cache entry is beinf
1122 filled. Change the definition of a COMPUTE variable to be defined
1123 when the cache entry is being used.
1124 * gen-icache.c: Update.

1142 * configure.in (enable-sim-icache): Clarify description. Make
1143 #define one of the defaults regardless of the cache. Probably
1144 should revamp and add a separate option.
