499 * ppc-instructions (Disabled_Exponent_Underflow): Increment
500 the exponent when denormalizing.
502 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
504 * configure: Regenerated to track ../common/aclocal.m4 changes.
506 1999-05-08 Felix Lee <flee@cygnus.com>
508 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
509 * configure: Regenerated to track ../common/aclocal.m4 changes.
511 1999-04-02 Keith Seitz <keiths@cygnus.com>
513 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
514 the frequency at which the poll_quit callback is called.
515 (poll_quit_count): New global.
516 (sim_io_poll_quit): Only call the poll_quit callback
517 after the specified POLL_QUIT_INTERVAL.
519 1999-02-22 Jim Lemke <jlemke@cygnus.com>
521 * dc-complex: Force expansion on all bits of field BO.
522 Previously, the least-significant (prediction) bit was ignored.
523 * ppc-instructions (conditional branches): Implement mpc860c0 option.
524 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
525 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

527 * interrupts.c (program_interrupt): Added handling for above interrupt.
529 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
531 Make the simulator compatible with the MPC750. It would be nicer
532 to make this a real multi-sim, but that's more work than we have
534 * emul_generic.c (emul_add_tree_options): Only require strict
535 alignment if it was explicitly requested at configuration time.
536 Don't make it the default for little-endian machines.
537 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
538 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
539 THRM2, THRM3): Plop in the MPC750 SPR registers.
540 (DABR): This is weird. This was HID5, but the PPC spec says this
541 should be DABR; why did some random processor use it for something
542 else? The HID5 entry dates back to the original checkin of the
543 simulator code in 1995, so remove it.
544 * sim_calls.c (register_names): Delete this; since the user can
545 now change GDB's list of register names dynamically, we can't
546 pretend there's a static mapping here.
547 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
548 function to get the register name. That ought to be accurate.
549 However, we're changing a compile-time dependency (using the
550 REGISTER_NAMES macro) into a link- and run-time dependency
551 (calling REGISTER_NAME, which happens to be a function call on the
554 1999-01-22 Jim Lemke <jlemke@cygnus.com>
556 * igen.c(gen_semantics_[ch]): setup/use of new option

560 psim.c(is_num - added, psim_options): Parse and init new option.
561 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
563 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
565 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

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

605 * sim_calls.c (sim_fetch_register, sim_store_register):
606 return zero when nothing to do.
608 1998-06-26 Michael Meissner <meissner@cygnus.com>
610 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
611 * configure: Regenerate.
612 * emul_{netbsd,unix}.c (toplevel): No longer try to include
613 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
615 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
617 * Makefile.in: The run target depended on a target psim$(EXEEXT),
618 but there was no such target, only plain psim. So I changed the
619 run target to depend on psim.
621 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
623 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
624 now defined in ../common/aclocal.m4, and the double definition causes
625 problems with AC_SUBST of EXEEXT.

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

1026 * When performance monitoring is disabled, it is still possible to
1027 determine the simulation speed by looking at the number of elapsed
1028 ticks recorded by the event queue.
1030 * psim.c (psim_write_register, psim_read_register): Force the cpu
1031 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1032 next cpu would be zero any way.
1034 * mon.c (mon_print_info): If possible, print the system cycle
1035 performance. This is an indication of the number of instructions
1038 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1040 * The code to allow an event queue to be updated during a signal
1041 was missing. For main.c, a cntrl-c simulation termination wasn't
1044 * The simulation would not correctly restart if an event requested
1045 that the simulation be halted.
1047 * psim.c (psim_options): Add hack to -i option to optionally
1048 include a level vis -i2.
1049 (psim_usage): Document.
1051 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

1063 (event_queue_init): Start the event queue out with processing
1065 (event_queue_tick): Check that processing isn't still being
1068 * gen-idecode.c (print_run_until_stop_body): Call
1069 event_queue_process_events to clear possibly pending events before
1070 starting a simulation run. Re-arange main loop so that simulator
1071 is correctly restarted when an event halts the simulation.
1073 * psim.c (psim_halt): Handle an event halting the simulation.
1074 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1077 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1079 * ppc-opcode-complex: Correct typo - was expanding ORA instead of

1097 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1098 to be initialized independant of the rest of the simulation
1099 initalization. Otherwize a trace option explictly set from gdb
1100 could be overridden by hw_trace.
1102 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1104 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1105 debug.c. It could be much simpler.

1153 output expressions in idecode.h file.

1164 * The code that put values in and extracted values from the cache
1165 was too compilicated. The cache table did not allow values to be
1166 computed from cache entries. #defines could only be used when a
1167 cache was present, remove the restriction.
1169 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1170 scratch variable is defined when a cache entry is beinf
1171 filled. Change the definition of a COMPUTE variable to be defined
1172 when the cache entry is being used.
1173 * gen-icache.c: Update.
1175 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1188 * igen.c (main): Change 'R' option so that it does not force the
1191 * configure.in (enable-sim-icache): Clarify description. Make
1192 #define one of the defaults regardless of the cache. Probably
1193 should revamp and add a separate option.

2730 * configure.in: Adjust filter flag so that default includes 32bit
