496 (sim_fetch_register, sim_store_register): Call
497 gdbarch_register_name directly, instead of going through
500 2000-10-24 Geoff Keating <geoffk@cygnus.com>

510 * events.c (event_queue_process): Call update_time_from_event
511 every time an event is removed from the queue.
512 (update_time_from_event): Delete assertion that a negative
513 time_from_event implies an empty event queue.
515 Fri Apr 28 15:53:54 2000 Andrew Cagney <cagney@b1.cygnus.com>

522 2000-03-25 Geoff Keating <geoffk@cygnus.com>
524 * ppc-instructions (Disabled_Exponent_Underflow): Increment
525 the exponent when denormalizing.
527 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
529 * configure: Regenerated to track ../common/aclocal.m4 changes.
531 1999-05-08 Felix Lee <flee@cygnus.com>
533 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
534 * configure: Regenerated to track ../common/aclocal.m4 changes.
536 1999-04-02 Keith Seitz <keiths@cygnus.com>
538 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
539 the frequency at which the poll_quit callback is called.
540 (poll_quit_count): New global.
541 (sim_io_poll_quit): Only call the poll_quit callback
542 after the specified POLL_QUIT_INTERVAL.
544 1999-02-22 Jim Lemke <jlemke@cygnus.com>
546 * dc-complex: Force expansion on all bits of field BO.
547 Previously, the least-significant (prediction) bit was ignored.
548 * ppc-instructions (conditional branches): Implement mpc860c0 option.
549 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
550 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

552 * interrupts.c (program_interrupt): Added handling for above interrupt.
554 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
556 Make the simulator compatible with the MPC750. It would be nicer
557 to make this a real multi-sim, but that's more work than we have
559 * emul_generic.c (emul_add_tree_options): Only require strict
560 alignment if it was explicitly requested at configuration time.
561 Don't make it the default for little-endian machines.
562 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
563 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
564 THRM2, THRM3): Plop in the MPC750 SPR registers.
565 (DABR): This is weird. This was HID5, but the PPC spec says this
566 should be DABR; why did some random processor use it for something
567 else? The HID5 entry dates back to the original checkin of the
568 simulator code in 1995, so remove it.
569 * sim_calls.c (register_names): Delete this; since the user can
570 now change GDB's list of register names dynamically, we can't
571 pretend there's a static mapping here.
572 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
573 function to get the register name. That ought to be accurate.
574 However, we're changing a compile-time dependency (using the
575 REGISTER_NAMES macro) into a link- and run-time dependency
576 (calling REGISTER_NAME, which happens to be a function call on the
579 1999-01-22 Jim Lemke <jlemke@cygnus.com>

585 psim.c(is_num - added, psim_options): Parse and init new option.
586 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
588 1998-12-01 Ken Raeburn <raeburn@cygnus.com>

606 fractional type, so that quiet NaN's aren't treated like
609 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
611 * table.c (table_open): For cygwin hosts, we need to use the
612 return value from the read routine as the number of bytes to
613 process. This apparently is due to text-mode vs binary-mode. If
614 the mounts are done text-mode, then the size returnedby fstat()
615 may be different than the number of bytes "read" in text mode.
617 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
619 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

630 * sim_calls.c (sim_fetch_register, sim_store_register):
631 return zero when nothing to do.
633 1998-06-26 Michael Meissner <meissner@cygnus.com>

636 * configure: Regenerate.
637 * emul_{netbsd,unix}.c (toplevel): No longer try to include
638 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
640 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
642 * Makefile.in: The run target depended on a target psim$(EXEEXT),
643 but there was no such target, only plain psim. So I changed the
644 run target to depend on psim.
646 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
648 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
649 now defined in ../common/aclocal.m4, and the double definition causes
650 problems with AC_SUBST of EXEEXT.

1055 * psim.c (psim_write_register, psim_read_register): Force the cpu
1056 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1057 next cpu would be zero any way.
1059 * mon.c (mon_print_info): If possible, print the system cycle
1060 performance. This is an indication of the number of instructions
1063 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1065 * The code to allow an event queue to be updated during a signal
1066 was missing. For main.c, a cntrl-c simulation termination wasn't
1069 * The simulation would not correctly restart if an event requested
1070 that the simulation be halted.
1072 * psim.c (psim_options): Add hack to -i option to optionally
1073 include a level vis -i2.
1074 (psim_usage): Document.
1076 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

1093 * gen-idecode.c (print_run_until_stop_body): Call
1094 event_queue_process_events to clear possibly pending events before

1122 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1123 to be initialized independant of the rest of the simulation
1124 initalization. Otherwize a trace option explictly set from gdb
1125 could be overridden by hw_trace.
1127 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1129 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1130 debug.c. It could be much simpler.

1189 * The code that put values in and extracted values from the cache
1190 was too compilicated. The cache table did not allow values to be
1191 computed from cache entries. #defines could only be used when a
1192 cache was present, remove the restriction.
1194 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1195 scratch variable is defined when a cache entry is beinf
1196 filled. Change the definition of a COMPUTE variable to be defined
1197 when the cache entry is being used.
1198 * gen-icache.c: Update.
1200 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1213 * igen.c (main): Change 'R' option so that it does not force the
1216 * configure.in (enable-sim-icache): Clarify description. Make
1217 #define one of the defaults regardless of the cache. Probably
1218 should revamp and add a separate option.
