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

520 * ppc-instructions (Disabled_Exponent_Underflow): Increment
521 the exponent when denormalizing.
523 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
525 * configure: Regenerated to track ../common/aclocal.m4 changes.
527 1999-05-08 Felix Lee <flee@cygnus.com>
529 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
530 * configure: Regenerated to track ../common/aclocal.m4 changes.
532 1999-04-02 Keith Seitz <keiths@cygnus.com>
534 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
535 the frequency at which the poll_quit callback is called.
536 (poll_quit_count): New global.
537 (sim_io_poll_quit): Only call the poll_quit callback
538 after the specified POLL_QUIT_INTERVAL.
540 1999-02-22 Jim Lemke <jlemke@cygnus.com>
542 * dc-complex: Force expansion on all bits of field BO.
543 Previously, the least-significant (prediction) bit was ignored.
544 * ppc-instructions (conditional branches): Implement mpc860c0 option.
545 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
546 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

548 * interrupts.c (program_interrupt): Added handling for above interrupt.
550 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
552 Make the simulator compatible with the MPC750. It would be nicer
553 to make this a real multi-sim, but that's more work than we have
555 * emul_generic.c (emul_add_tree_options): Only require strict
556 alignment if it was explicitly requested at configuration time.
557 Don't make it the default for little-endian machines.
558 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
559 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
560 THRM2, THRM3): Plop in the MPC750 SPR registers.
561 (DABR): This is weird. This was HID5, but the PPC spec says this
562 should be DABR; why did some random processor use it for something
563 else? The HID5 entry dates back to the original checkin of the
564 simulator code in 1995, so remove it.
565 * sim_calls.c (register_names): Delete this; since the user can
566 now change GDB's list of register names dynamically, we can't
567 pretend there's a static mapping here.
568 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
569 function to get the register name. That ought to be accurate.
570 However, we're changing a compile-time dependency (using the
571 REGISTER_NAMES macro) into a link- and run-time dependency
572 (calling REGISTER_NAME, which happens to be a function call on the
575 1999-01-22 Jim Lemke <jlemke@cygnus.com>
577 * igen.c(gen_semantics_[ch]): setup/use of new option

581 psim.c(is_num - added, psim_options): Parse and init new option.
582 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
584 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
586 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

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

627 return zero when nothing to do.
629 1998-06-26 Michael Meissner <meissner@cygnus.com>
631 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
632 * configure: Regenerate.
633 * emul_{netbsd,unix}.c (toplevel): No longer try to include
634 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
636 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
638 * Makefile.in: The run target depended on a target psim$(EXEEXT),
639 but there was no such target, only plain psim. So I changed the
640 run target to depend on psim.
642 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
644 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
645 now defined in ../common/aclocal.m4, and the double definition causes
646 problems with AC_SUBST of EXEEXT.

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

969 (device_add_ihandle_runtime_property): Update.

982 Tue Feb 4 17:44:51 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
984 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
985 works for normal and boolean table entries.
987 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now

1010 or doubles clock interrupts.

1045 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1047 * When performance monitoring is disabled, it is still possible to
1048 determine the simulation speed by looking at the number of elapsed
1049 ticks recorded by the event queue.
1051 * psim.c (psim_write_register, psim_read_register): Force the cpu
1052 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1053 next cpu would be zero any way.
1055 * mon.c (mon_print_info): If possible, print the system cycle
1056 performance. This is an indication of the number of instructions
1059 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1061 * The code to allow an event queue to be updated during a signal
1062 was missing. For main.c, a cntrl-c simulation termination wasn't
1065 * The simulation would not correctly restart if an event requested
1066 that the simulation be halted.
1068 * psim.c (psim_options): Add hack to -i option to optionally
1069 include a level vis -i2.
1070 (psim_usage): Document.
1072 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

1084 (event_queue_init): Start the event queue out with processing
1086 (event_queue_tick): Check that processing isn't still being
1089 * gen-idecode.c (print_run_until_stop_body): Call
1090 event_queue_process_events to clear possibly pending events before
1091 starting a simulation run. Re-arange main loop so that simulator
1092 is correctly restarted when an event halts the simulation.
1094 * psim.c (psim_halt): Handle an event halting the simulation.
1095 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1098 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1100 * ppc-opcode-complex: Correct typo - was expanding ORA instead of

1106 here. Update to new format.

1118 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1119 to be initialized independant of the rest of the simulation
1120 initalization. Otherwize a trace option explictly set from gdb
1121 could be overridden by hw_trace.
1123 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1125 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1126 debug.c. It could be much simpler.

1168 the form <name>_is_<const> where it is a boolean field, generate
1169 the result of the expression instead of the expression its self.

1174 output expressions in idecode.h file.
1176 * gen-icache.c (print_icache_body): Output them here.
1178 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1183 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1185 * The code that put values in and extracted values from the cache
1186 was too compilicated. The cache table did not allow values to be
1187 computed from cache entries. #defines could only be used when a
1188 cache was present, remove the restriction.
1190 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1191 scratch variable is defined when a cache entry is beinf
1192 filled. Change the definition of a COMPUTE variable to be defined
1193 when the cache entry is being used.
1194 * gen-icache.c: Update.
1196 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1209 * igen.c (main): Change 'R' option so that it does not force the
1212 * configure.in (enable-sim-icache): Clarify description. Make
1213 #define one of the defaults regardless of the cache. Probably
1214 should revamp and add a separate option.

1229 device after it was deleted. Instead add and remove cap's from the
1230 cap db as they are created and deleted. This ensuring that a
1231 capibility is only used during the lifetime of the corresponding
