493 time_from_event implies an empty event queue.

504 * ppc-instructions (Disabled_Exponent_Underflow): Increment
505 the exponent when denormalizing.
507 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
509 * configure: Regenerated to track ../common/aclocal.m4 changes.
511 1999-05-08 Felix Lee <flee@cygnus.com>
513 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
514 * configure: Regenerated to track ../common/aclocal.m4 changes.
516 1999-04-02 Keith Seitz <keiths@cygnus.com>
518 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
519 the frequency at which the poll_quit callback is called.
520 (poll_quit_count): New global.
521 (sim_io_poll_quit): Only call the poll_quit callback
522 after the specified POLL_QUIT_INTERVAL.
524 1999-02-22 Jim Lemke <jlemke@cygnus.com>
526 * dc-complex: Force expansion on all bits of field BO.
527 Previously, the least-significant (prediction) bit was ignored.
528 * ppc-instructions (conditional branches): Implement mpc860c0 option.
529 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
530 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

532 * interrupts.c (program_interrupt): Added handling for above interrupt.
534 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
536 Make the simulator compatible with the MPC750. It would be nicer
537 to make this a real multi-sim, but that's more work than we have
539 * emul_generic.c (emul_add_tree_options): Only require strict
540 alignment if it was explicitly requested at configuration time.
541 Don't make it the default for little-endian machines.
542 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
543 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
544 THRM2, THRM3): Plop in the MPC750 SPR registers.
545 (DABR): This is weird. This was HID5, but the PPC spec says this
546 should be DABR; why did some random processor use it for something
547 else? The HID5 entry dates back to the original checkin of the
548 simulator code in 1995, so remove it.
549 * sim_calls.c (register_names): Delete this; since the user can
550 now change GDB's list of register names dynamically, we can't
551 pretend there's a static mapping here.
552 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
553 function to get the register name. That ought to be accurate.
554 However, we're changing a compile-time dependency (using the
555 REGISTER_NAMES macro) into a link- and run-time dependency
556 (calling REGISTER_NAME, which happens to be a function call on the
559 1999-01-22 Jim Lemke <jlemke@cygnus.com>
561 * igen.c(gen_semantics_[ch]): setup/use of new option

565 psim.c(is_num - added, psim_options): Parse and init new option.
566 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
568 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
570 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

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

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

969 works for normal and boolean table entries.

1032 determine the simulation speed by looking at the number of elapsed
1033 ticks recorded by the event queue.
1035 * psim.c (psim_write_register, psim_read_register): Force the cpu
1036 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1037 next cpu would be zero any way.
1039 * mon.c (mon_print_info): If possible, print the system cycle
1040 performance. This is an indication of the number of instructions
1043 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1045 * The code to allow an event queue to be updated during a signal
1046 was missing. For main.c, a cntrl-c simulation termination wasn't
1049 * The simulation would not correctly restart if an event requested
1050 that the simulation be halted.
1052 * psim.c (psim_options): Add hack to -i option to optionally
1053 include a level vis -i2.
1054 (psim_usage): Document.
1056 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

1070 (event_queue_tick): Check that processing isn't still being
1073 * gen-idecode.c (print_run_until_stop_body): Call
1074 event_queue_process_events to clear possibly pending events before

1079 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1082 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1102 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1103 to be initialized independant of the rest of the simulation
1104 initalization. Otherwize a trace option explictly set from gdb
1105 could be overridden by hw_trace.
1107 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1109 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1110 debug.c. It could be much simpler.

1158 output expressions in idecode.h file.

1169 * The code that put values in and extracted values from the cache
1170 was too compilicated. The cache table did not allow values to be
1171 computed from cache entries. #defines could only be used when a
1172 cache was present, remove the restriction.
1174 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1175 scratch variable is defined when a cache entry is beinf
1176 filled. Change the definition of a COMPUTE variable to be defined
1177 when the cache entry is being used.
1178 * gen-icache.c: Update.
1180 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1193 * igen.c (main): Change 'R' option so that it does not force the
1196 * configure.in (enable-sim-icache): Clarify description. Make
1197 #define one of the defaults regardless of the cache. Probably
1198 should revamp and add a separate option.

2735 * configure.in: Adjust filter flag so that default includes 32bit
