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

508 (update_time_from_event): Trace full event queue.
510 2000-03-25 Geoff Keating <geoffk@cygnus.com>
512 * ppc-instructions (Disabled_Exponent_Underflow): Increment
513 the exponent when denormalizing.
515 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
517 * configure: Regenerated to track ../common/aclocal.m4 changes.
519 1999-05-08 Felix Lee <flee@cygnus.com>
521 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
522 * configure: Regenerated to track ../common/aclocal.m4 changes.
524 1999-04-02 Keith Seitz <keiths@cygnus.com>
526 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
527 the frequency at which the poll_quit callback is called.
528 (poll_quit_count): New global.
529 (sim_io_poll_quit): Only call the poll_quit callback
530 after the specified POLL_QUIT_INTERVAL.
532 1999-02-22 Jim Lemke <jlemke@cygnus.com>
534 * dc-complex: Force expansion on all bits of field BO.
535 Previously, the least-significant (prediction) bit was ignored.
536 * ppc-instructions (conditional branches): Implement mpc860c0 option.
537 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
538 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
539 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
540 * interrupts.c (program_interrupt): Added handling for above interrupt.
542 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
544 Make the simulator compatible with the MPC750. It would be nicer
545 to make this a real multi-sim, but that's more work than we have
547 * emul_generic.c (emul_add_tree_options): Only require strict
548 alignment if it was explicitly requested at configuration time.
549 Don't make it the default for little-endian machines.
550 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
551 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
552 THRM2, THRM3): Plop in the MPC750 SPR registers.
553 (DABR): This is weird. This was HID5, but the PPC spec says this
554 should be DABR; why did some random processor use it for something
555 else? The HID5 entry dates back to the original checkin of the
556 simulator code in 1995, so remove it.
557 * sim_calls.c (register_names): Delete this; since the user can
558 now change GDB's list of register names dynamically, we can't
559 pretend there's a static mapping here.
560 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
561 function to get the register name. That ought to be accurate.
562 However, we're changing a compile-time dependency (using the
563 REGISTER_NAMES macro) into a link- and run-time dependency
564 (calling REGISTER_NAME, which happens to be a function call on the
567 1999-01-22 Jim Lemke <jlemke@cygnus.com>
569 * igen.c(gen_semantics_[ch]): setup/use of new option
571 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.

573 psim.c(is_num - added, psim_options): Parse and init new option.
574 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
576 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
578 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

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

618 * sim_calls.c (sim_fetch_register, sim_store_register):
619 return zero when nothing to do.
621 1998-06-26 Michael Meissner <meissner@cygnus.com>
623 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
624 * configure: Regenerate.
625 * emul_{netbsd,unix}.c (toplevel): No longer try to include
626 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
628 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
630 * Makefile.in: The run target depended on a target psim$(EXEEXT),
631 but there was no such target, only plain psim. So I changed the
632 run target to depend on psim.
634 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
636 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
637 now defined in ../common/aclocal.m4, and the double definition causes
638 problems with AC_SUBST of EXEEXT.

733 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,

976 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
977 works for normal and boolean table entries.
979 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now

1037 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1039 * When performance monitoring is disabled, it is still possible to
1040 determine the simulation speed by looking at the number of elapsed
1041 ticks recorded by the event queue.
1043 * psim.c (psim_write_register, psim_read_register): Force the cpu
1044 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1045 next cpu would be zero any way.
1047 * mon.c (mon_print_info): If possible, print the system cycle
1048 performance. This is an indication of the number of instructions
1051 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1053 * The code to allow an event queue to be updated during a signal
1054 was missing. For main.c, a cntrl-c simulation termination wasn't
1057 * The simulation would not correctly restart if an event requested
1058 that the simulation be halted.
1060 * psim.c (psim_options): Add hack to -i option to optionally
1061 include a level vis -i2.
1062 (psim_usage): Document.
1064 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

1078 (event_queue_tick): Check that processing isn't still being
1081 * gen-idecode.c (print_run_until_stop_body): Call
1082 event_queue_process_events to clear possibly pending events before
1083 starting a simulation run. Re-arange main loop so that simulator
1084 is correctly restarted when an event halts the simulation.
1086 * psim.c (psim_halt): Handle an event halting the simulation.
1087 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1090 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1092 * ppc-opcode-complex: Correct typo - was expanding ORA instead of

1098 here. Update to new format.

1110 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1111 to be initialized independant of the rest of the simulation
1112 initalization. Otherwize a trace option explictly set from gdb
1113 could be overridden by hw_trace.
1115 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1117 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1118 debug.c. It could be much simpler.

1160 the form <name>_is_<const> where it is a boolean field, generate
1161 the result of the expression instead of the expression its self.

1166 output expressions in idecode.h file.
1168 * gen-icache.c (print_icache_body): Output them here.
1170 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1175 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1177 * The code that put values in and extracted values from the cache
1178 was too compilicated. The cache table did not allow values to be
1179 computed from cache entries. #defines could only be used when a
1180 cache was present, remove the restriction.
1182 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1183 scratch variable is defined when a cache entry is beinf
1184 filled. Change the definition of a COMPUTE variable to be defined
1185 when the cache entry is being used.
1186 * gen-icache.c: Update.
1188 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1201 * igen.c (main): Change 'R' option so that it does not force the
1204 * configure.in (enable-sim-icache): Clarify description. Make
1205 #define one of the defaults regardless of the cache. Probably
1206 should revamp and add a separate option.

1221 device after it was deleted. Instead add and remove cap's from the
1222 cap db as they are created and deleted. This ensuring that a
