490 the exponent when denormalizing.
492 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
494 * configure: Regenerated to track ../common/aclocal.m4 changes.
496 1999-05-08 Felix Lee <flee@cygnus.com>
498 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
499 * configure: Regenerated to track ../common/aclocal.m4 changes.
501 1999-04-02 Keith Seitz <keiths@cygnus.com>
503 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
504 the frequency at which the poll_quit callback is called.
505 (poll_quit_count): New global.
506 (sim_io_poll_quit): Only call the poll_quit callback
507 after the specified POLL_QUIT_INTERVAL.
509 1999-02-22 Jim Lemke <jlemke@cygnus.com>
511 * dc-complex: Force expansion on all bits of field BO.
512 Previously, the least-significant (prediction) bit was ignored.
513 * ppc-instructions (conditional branches): Implement mpc860c0 option.
514 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
515 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
516 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
517 * interrupts.c (program_interrupt): Added handling for above interrupt.
519 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
521 Make the simulator compatible with the MPC750. It would be nicer
522 to make this a real multi-sim, but that's more work than we have
524 * emul_generic.c (emul_add_tree_options): Only require strict
525 alignment if it was explicitly requested at configuration time.
526 Don't make it the default for little-endian machines.
527 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
528 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
529 THRM2, THRM3): Plop in the MPC750 SPR registers.
530 (DABR): This is weird. This was HID5, but the PPC spec says this
531 should be DABR; why did some random processor use it for something
532 else? The HID5 entry dates back to the original checkin of the
533 simulator code in 1995, so remove it.
534 * sim_calls.c (register_names): Delete this; since the user can
535 now change GDB's list of register names dynamically, we can't
536 pretend there's a static mapping here.
537 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
538 function to get the register name. That ought to be accurate.
539 However, we're changing a compile-time dependency (using the
540 REGISTER_NAMES macro) into a link- and run-time dependency
541 (calling REGISTER_NAME, which happens to be a function call on the
544 1999-01-22 Jim Lemke <jlemke@cygnus.com>
546 * igen.c(gen_semantics_[ch]): setup/use of new option
548 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
549 ppc-instructions(the four branch insn groups): detect problematic br's.
550 psim.c(is_num - added, psim_options): Parse and init new option.
551 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
553 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
555 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

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

598 1998-06-26 Michael Meissner <meissner@cygnus.com>
600 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
601 * configure: Regenerate.
602 * emul_{netbsd,unix}.c (toplevel): No longer try to include
603 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
605 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
607 * Makefile.in: The run target depended on a target psim$(EXEEXT),
608 but there was no such target, only plain psim. So I changed the
609 run target to depend on psim.
611 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
613 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
614 now defined in ../common/aclocal.m4, and the double definition causes
615 problems with AC_SUBST of EXEEXT.

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

1020 * psim.c (psim_write_register, psim_read_register): Force the cpu
1021 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1022 next cpu would be zero any way.
1024 * mon.c (mon_print_info): If possible, print the system cycle
1025 performance. This is an indication of the number of instructions
1028 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1030 * The code to allow an event queue to be updated during a signal
1031 was missing. For main.c, a cntrl-c simulation termination wasn't
1034 * The simulation would not correctly restart if an event requested
1035 that the simulation be halted.
1037 * psim.c (psim_options): Add hack to -i option to optionally
1038 include a level vis -i2.
1039 (psim_usage): Document.
1041 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

1058 * gen-idecode.c (print_run_until_stop_body): Call

1087 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1088 to be initialized independant of the rest of the simulation
1089 initalization. Otherwize a trace option explictly set from gdb
1090 could be overridden by hw_trace.
1092 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1094 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,

1155 was too compilicated. The cache table did not allow values to be
1156 computed from cache entries. #defines could only be used when a
1157 cache was present, remove the restriction.
1159 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1160 scratch variable is defined when a cache entry is beinf
1161 filled. Change the definition of a COMPUTE variable to be defined
1162 when the cache entry is being used.
1163 * gen-icache.c: Update.
1165 * ld-cache.h, ld-cache.c: Change field names so that their meaning
