488 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
489 * configure: Regenerated to track ../common/aclocal.m4 changes.
491 1999-04-02 Keith Seitz <keiths@cygnus.com>
493 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
494 the frequency at which the poll_quit callback is called.
495 (poll_quit_count): New global.
496 (sim_io_poll_quit): Only call the poll_quit callback
497 after the specified POLL_QUIT_INTERVAL.
499 1999-02-22 Jim Lemke <jlemke@cygnus.com>
501 * dc-complex: Force expansion on all bits of field BO.
502 Previously, the least-significant (prediction) bit was ignored.
503 * ppc-instructions (conditional branches): Implement mpc860c0 option.
504 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
505 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
506 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
507 * interrupts.c (program_interrupt): Added handling for above interrupt.
509 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
511 Make the simulator compatible with the MPC750. It would be nicer
512 to make this a real multi-sim, but that's more work than we have
514 * emul_generic.c (emul_add_tree_options): Only require strict
515 alignment if it was explicitly requested at configuration time.
516 Don't make it the default for little-endian machines.
517 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
518 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
519 THRM2, THRM3): Plop in the MPC750 SPR registers.
520 (DABR): This is weird. This was HID5, but the PPC spec says this
521 should be DABR; why did some random processor use it for something
522 else? The HID5 entry dates back to the original checkin of the
523 simulator code in 1995, so remove it.
524 * sim_calls.c (register_names): Delete this; since the user can
525 now change GDB's list of register names dynamically, we can't
526 pretend there's a static mapping here.
527 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
528 function to get the register name. That ought to be accurate.
529 However, we're changing a compile-time dependency (using the
530 REGISTER_NAMES macro) into a link- and run-time dependency
531 (calling REGISTER_NAME, which happens to be a function call on the
534 1999-01-22 Jim Lemke <jlemke@cygnus.com>
536 * igen.c(gen_semantics_[ch]): setup/use of new option
538 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
539 ppc-instructions(the four branch insn groups): detect problematic br's.
540 psim.c(is_num - added, psim_options): Parse and init new option.
541 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
543 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
545 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

556 poll the external environment.
558 1998-11-19 Michael Meissner <meissner@cygnus.com>
560 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
561 fractional type, so that quiet NaN's aren't treated like
564 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
566 * table.c (table_open): For cygwin hosts, we need to use the
567 return value from the read routine as the number of bytes to
568 process. This apparently is due to text-mode vs binary-mode. If
569 the mounts are done text-mode, then the size returnedby fstat()
570 may be different than the number of bytes "read" in text mode.
572 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
574 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

585 * sim_calls.c (sim_fetch_register, sim_store_register):
586 return zero when nothing to do.
588 1998-06-26 Michael Meissner <meissner@cygnus.com>
590 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
591 * configure: Regenerate.
592 * emul_{netbsd,unix}.c (toplevel): No longer try to include
593 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
595 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
597 * Makefile.in: The run target depended on a target psim$(EXEEXT),
598 but there was no such target, only plain psim. So I changed the
599 run target to depend on psim.
601 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
603 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
604 now defined in ../common/aclocal.m4, and the double definition causes
605 problems with AC_SUBST of EXEEXT.

608 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>

815 * Makefile.in (tmp-hw, tmp-pk): Use for loop to eliminate duplicates

928 (device_add_ihandle_runtime_property): Update.

936 * gen-icache.c (print_icache_extraction): Add a reason parameter.
937 Augment each extracted field with a comment citing the codes

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

969 or doubles clock interrupts.
972 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1007 determine the simulation speed by looking at the number of elapsed
1008 ticks recorded by the event queue.
1010 * psim.c (psim_write_register, psim_read_register): Force the cpu
1011 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1012 next cpu would be zero any way.
1014 * mon.c (mon_print_info): If possible, print the system cycle
1015 performance. This is an indication of the number of instructions
1018 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1020 * The code to allow an event queue to be updated during a signal
1021 was missing. For main.c, a cntrl-c simulation termination wasn't
1024 * The simulation would not correctly restart if an event requested
1025 that the simulation be halted.
1027 * psim.c (psim_options): Add hack to -i option to optionally
1028 include a level vis -i2.

1149 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1150 scratch variable is defined when a cache entry is beinf

1153 * gen-icache.c: Update.
