497 are simply renaming functions, to permit use of XCONCAT2 in both
498 the macro name and the arguments in a use of such a definition.
500 2000-11-15 Jim Blandy <jimb@redhat.com>
502 * sim_calls.c: Doc fix.
503 (sim_fetch_register, sim_store_register): Call
504 gdbarch_register_name directly, instead of going through
507 2000-10-24 Geoff Keating <geoffk@cygnus.com>

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

531 * ppc-instructions (Disabled_Exponent_Underflow): Increment
532 the exponent when denormalizing.
534 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
536 * configure: Regenerated to track ../common/aclocal.m4 changes.
538 1999-05-08 Felix Lee <flee@cygnus.com>
540 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
541 * configure: Regenerated to track ../common/aclocal.m4 changes.
543 1999-04-02 Keith Seitz <keiths@cygnus.com>
545 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
546 the frequency at which the poll_quit callback is called.
547 (poll_quit_count): New global.
548 (sim_io_poll_quit): Only call the poll_quit callback
549 after the specified POLL_QUIT_INTERVAL.
551 1999-02-22 Jim Lemke <jlemke@cygnus.com>
553 * dc-complex: Force expansion on all bits of field BO.
554 Previously, the least-significant (prediction) bit was ignored.
555 * ppc-instructions (conditional branches): Implement mpc860c0 option.
556 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
557 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

559 * interrupts.c (program_interrupt): Added handling for above interrupt.
561 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
563 Make the simulator compatible with the MPC750. It would be nicer
564 to make this a real multi-sim, but that's more work than we have
566 * emul_generic.c (emul_add_tree_options): Only require strict
567 alignment if it was explicitly requested at configuration time.
568 Don't make it the default for little-endian machines.
569 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
570 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
571 THRM2, THRM3): Plop in the MPC750 SPR registers.
572 (DABR): This is weird. This was HID5, but the PPC spec says this
573 should be DABR; why did some random processor use it for something
574 else? The HID5 entry dates back to the original checkin of the
575 simulator code in 1995, so remove it.
576 * sim_calls.c (register_names): Delete this; since the user can
577 now change GDB's list of register names dynamically, we can't
578 pretend there's a static mapping here.
579 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
580 function to get the register name. That ought to be accurate.
581 However, we're changing a compile-time dependency (using the
582 REGISTER_NAMES macro) into a link- and run-time dependency
583 (calling REGISTER_NAME, which happens to be a function call on the
586 1999-01-22 Jim Lemke <jlemke@cygnus.com>
588 * igen.c(gen_semantics_[ch]): setup/use of new option

592 psim.c(is_num - added, psim_options): Parse and init new option.
593 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
595 1998-12-01 Ken Raeburn <raeburn@cygnus.com>

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

643 * configure: Regenerate.
644 * emul_{netbsd,unix}.c (toplevel): No longer try to include
645 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
647 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
649 * Makefile.in: The run target depended on a target psim$(EXEEXT),
650 but there was no such target, only plain psim. So I changed the
651 run target to depend on psim.
653 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
655 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
656 now defined in ../common/aclocal.m4, and the double definition causes
657 problems with AC_SUBST of EXEEXT.

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

1062 * psim.c (psim_write_register, psim_read_register): Force the cpu
1063 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1064 next cpu would be zero any way.
1066 * mon.c (mon_print_info): If possible, print the system cycle
1067 performance. This is an indication of the number of instructions
1070 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1072 * The code to allow an event queue to be updated during a signal
1073 was missing. For main.c, a cntrl-c simulation termination wasn't
1076 * The simulation would not correctly restart if an event requested
1077 that the simulation be halted.
1079 * psim.c (psim_options): Add hack to -i option to optionally
1080 include a level vis -i2.
1081 (psim_usage): Document.
1083 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

1100 * gen-idecode.c (print_run_until_stop_body): Call
1101 event_queue_process_events to clear possibly pending events before

1129 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1130 to be initialized independant of the rest of the simulation
1131 initalization. Otherwize a trace option explictly set from gdb
1132 could be overridden by hw_trace.
1134 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1136 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1137 debug.c. It could be much simpler.

1196 * The code that put values in and extracted values from the cache
1197 was too compilicated. The cache table did not allow values to be
1198 computed from cache entries. #defines could only be used when a
1199 cache was present, remove the restriction.
1201 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1202 scratch variable is defined when a cache entry is beinf
1203 filled. Change the definition of a COMPUTE variable to be defined
1204 when the cache entry is being used.
1205 * gen-icache.c: Update.
1207 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1220 * igen.c (main): Change 'R' option so that it does not force the
1223 * configure.in (enable-sim-icache): Clarify description. Make
1224 #define one of the defaults regardless of the cache. Probably
1225 should revamp and add a separate option.

3688 pointer) and its external (or what is passed to a client)
3689 representation (a phandle). Implement using the cap object
3690 attached to the root node.
3692 * device.c (device_to_external) : Ditto
3693 * device.c (external_to_device_instance) : Ditto but for ihandle
3694 and device instance.
3695 * device.c (device_instance_to_external) : Ditto
3697 * Makefile (device.o): Add dependency on cap.
3699 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3700 needing to translate between internal and external representations
3701 changed to use the external_to_device et.al. device operations.
3702 * emul_chirp.c (chirp_emul_*) : Ditto
3704 * Makefile (emul_chirp.o): Remove dependency on cap
3706 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3708 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3709 on OpenBoot note section.
3711 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3713 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3714 read/write calls for buffer transfers. This will cause a fault to
3715 occure if the transfer fails. CHRP catches the fault while the
3716 others suffer the consequences.
3717 (emul_read_buffer): Ditto.
3718 (emul_write_word): Ditto.
3719 (emul_read_word): Ditto.
3720 (emul_read_string): Ditto.
3722 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3724 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3725 emul_generic (emul_blr_instruction): Use a real blr instruction to
3726 return from a client service call.
3728 * emul_chirp.c (services): Add all OpenBoot services to table.
3730 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3731 (emul_chirp_create) : Use names instead of numbers for
3732 instructions being stored in memory.
3734 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3736 * Makefile.in (maintainer-clean): Remove .log, core and *.core
3737 (From NetBSD) files.
