488 * configure: Regenerated to track ../common/aclocal.m4 changes.
490 1999-05-08 Felix Lee <flee@cygnus.com>
492 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
493 * configure: Regenerated to track ../common/aclocal.m4 changes.
495 1999-04-02 Keith Seitz <keiths@cygnus.com>
497 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
498 the frequency at which the poll_quit callback is called.
499 (poll_quit_count): New global.
500 (sim_io_poll_quit): Only call the poll_quit callback
501 after the specified POLL_QUIT_INTERVAL.
503 1999-02-22 Jim Lemke <jlemke@cygnus.com>
505 * dc-complex: Force expansion on all bits of field BO.
506 Previously, the least-significant (prediction) bit was ignored.
507 * ppc-instructions (conditional branches): Implement mpc860c0 option.
508 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
509 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
510 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
511 * interrupts.c (program_interrupt): Added handling for above interrupt.
513 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
515 Make the simulator compatible with the MPC750. It would be nicer
516 to make this a real multi-sim, but that's more work than we have
518 * emul_generic.c (emul_add_tree_options): Only require strict
519 alignment if it was explicitly requested at configuration time.
520 Don't make it the default for little-endian machines.
521 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
522 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
523 THRM2, THRM3): Plop in the MPC750 SPR registers.
524 (DABR): This is weird. This was HID5, but the PPC spec says this
525 should be DABR; why did some random processor use it for something
526 else? The HID5 entry dates back to the original checkin of the
527 simulator code in 1995, so remove it.
528 * sim_calls.c (register_names): Delete this; since the user can
529 now change GDB's list of register names dynamically, we can't
530 pretend there's a static mapping here.
531 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
532 function to get the register name. That ought to be accurate.
533 However, we're changing a compile-time dependency (using the
534 REGISTER_NAMES macro) into a link- and run-time dependency
535 (calling REGISTER_NAME, which happens to be a function call on the
538 1999-01-22 Jim Lemke <jlemke@cygnus.com>
540 * igen.c(gen_semantics_[ch]): setup/use of new option
542 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
543 ppc-instructions(the four branch insn groups): detect problematic br's.
544 psim.c(is_num - added, psim_options): Parse and init new option.
545 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
547 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
549 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

559 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
560 poll the external environment.
562 1998-11-19 Michael Meissner <meissner@cygnus.com>
564 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
565 fractional type, so that quiet NaN's aren't treated like
568 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
570 * table.c (table_open): For cygwin hosts, we need to use the
571 return value from the read routine as the number of bytes to
572 process. This apparently is due to text-mode vs binary-mode. If
573 the mounts are done text-mode, then the size returnedby fstat()
574 may be different than the number of bytes "read" in text mode.
576 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
578 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

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

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

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

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

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

1011 determine the simulation speed by looking at the number of elapsed
1012 ticks recorded by the event queue.
1014 * psim.c (psim_write_register, psim_read_register): Force the cpu
1015 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1016 next cpu would be zero any way.
1018 * mon.c (mon_print_info): If possible, print the system cycle
1019 performance. This is an indication of the number of instructions
1022 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1024 * The code to allow an event queue to be updated during a signal
1025 was missing. For main.c, a cntrl-c simulation termination wasn't
1028 * The simulation would not correctly restart if an event requested
1029 that the simulation be halted.
1031 * psim.c (psim_options): Add hack to -i option to optionally
1032 include a level vis -i2.
1033 (psim_usage): Document.
1035 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

1081 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1082 to be initialized independant of the rest of the simulation
1083 initalization. Otherwize a trace option explictly set from gdb
1084 could be overridden by hw_trace.
1086 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1088 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,

1149 was too compilicated. The cache table did not allow values to be
1150 computed from cache entries. #defines could only be used when a
1151 cache was present, remove the restriction.
1153 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1154 scratch variable is defined when a cache entry is beinf

1156 when the cache entry is being used.
1157 * gen-icache.c: Update.
