512 open syscall to the numbers supported by the host.
514 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
516 * sim-endian.h: Don't have parameters on macro definitions which
517 are simply renaming functions, to permit use of XCONCAT2 in both
518 the macro name and the arguments in a use of such a definition.
520 2000-11-15 Jim Blandy <jimb@redhat.com>
522 * sim_calls.c: Doc fix.
523 (sim_fetch_register, sim_store_register): Call
524 gdbarch_register_name directly, instead of going through

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

551 * ppc-instructions (Disabled_Exponent_Underflow): Increment
552 the exponent when denormalizing.
554 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
556 * configure: Regenerated to track ../common/aclocal.m4 changes.
558 1999-05-08 Felix Lee <flee@cygnus.com>
560 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
561 * configure: Regenerated to track ../common/aclocal.m4 changes.
563 1999-04-02 Keith Seitz <keiths@cygnus.com>
565 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
566 the frequency at which the poll_quit callback is called.
567 (poll_quit_count): New global.
568 (sim_io_poll_quit): Only call the poll_quit callback
569 after the specified POLL_QUIT_INTERVAL.
571 1999-02-22 Jim Lemke <jlemke@cygnus.com>
573 * dc-complex: Force expansion on all bits of field BO.
574 Previously, the least-significant (prediction) bit was ignored.
575 * ppc-instructions (conditional branches): Implement mpc860c0 option.
576 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
577 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

579 * interrupts.c (program_interrupt): Added handling for above interrupt.
581 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
583 Make the simulator compatible with the MPC750. It would be nicer
584 to make this a real multi-sim, but that's more work than we have
586 * emul_generic.c (emul_add_tree_options): Only require strict
587 alignment if it was explicitly requested at configuration time.
588 Don't make it the default for little-endian machines.
589 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
590 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
591 THRM2, THRM3): Plop in the MPC750 SPR registers.
592 (DABR): This is weird. This was HID5, but the PPC spec says this
593 should be DABR; why did some random processor use it for something
594 else? The HID5 entry dates back to the original checkin of the
595 simulator code in 1995, so remove it.
596 * sim_calls.c (register_names): Delete this; since the user can
597 now change GDB's list of register names dynamically, we can't
598 pretend there's a static mapping here.
599 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
600 function to get the register name. That ought to be accurate.
601 However, we're changing a compile-time dependency (using the
602 REGISTER_NAMES macro) into a link- and run-time dependency
603 (calling REGISTER_NAME, which happens to be a function call on the
606 1999-01-22 Jim Lemke <jlemke@cygnus.com>
608 * igen.c(gen_semantics_[ch]): setup/use of new option

612 psim.c(is_num - added, psim_options): Parse and init new option.
613 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
615 1998-12-01 Ken Raeburn <raeburn@cygnus.com>

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

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

1079 determine the simulation speed by looking at the number of elapsed
1080 ticks recorded by the event queue.
1082 * psim.c (psim_write_register, psim_read_register): Force the cpu
1083 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1084 next cpu would be zero any way.
1086 * mon.c (mon_print_info): If possible, print the system cycle
1087 performance. This is an indication of the number of instructions
1090 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1092 * The code to allow an event queue to be updated during a signal
1093 was missing. For main.c, a cntrl-c simulation termination wasn't
1096 * The simulation would not correctly restart if an event requested
1097 that the simulation be halted.
1099 * psim.c (psim_options): Add hack to -i option to optionally
1100 include a level vis -i2.
1101 (psim_usage): Document.

1149 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1150 to be initialized independant of the rest of the simulation
1151 initalization. Otherwize a trace option explictly set from gdb
1152 could be overridden by hw_trace.
1154 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1156 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1157 debug.c. It could be much simpler.

1216 * The code that put values in and extracted values from the cache
1217 was too compilicated. The cache table did not allow values to be
1218 computed from cache entries. #defines could only be used when a
1219 cache was present, remove the restriction.
1221 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1222 scratch variable is defined when a cache entry is beinf
1223 filled. Change the definition of a COMPUTE variable to be defined
1224 when the cache entry is being used.
1225 * gen-icache.c: Update.
1227 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1243 * configure.in (enable-sim-icache): Clarify description. Make
1244 #define one of the defaults regardless of the cache. Probably
1245 should revamp and add a separate option.

3704 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3706 * device.c (external_to_device) : New function that provides a
3707 standard mapping between a devices internal representation (a
3708 pointer) and its external (or what is passed to a client)
3709 representation (a phandle). Implement using the cap object
3710 attached to the root node.
3712 * device.c (device_to_external) : Ditto
3713 * device.c (external_to_device_instance) : Ditto but for ihandle
3714 and device instance.
3715 * device.c (device_instance_to_external) : Ditto
3717 * Makefile (device.o): Add dependency on cap.
3719 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3720 needing to translate between internal and external representations
3721 changed to use the external_to_device et.al. device operations.
3722 * emul_chirp.c (chirp_emul_*) : Ditto
3724 * Makefile (emul_chirp.o): Remove dependency on cap
3726 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3728 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3729 on OpenBoot note section.
3731 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3733 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3734 read/write calls for buffer transfers. This will cause a fault to
3735 occure if the transfer fails. CHRP catches the fault while the
3736 others suffer the consequences.
3737 (emul_read_buffer): Ditto.
3738 (emul_write_word): Ditto.
3739 (emul_read_word): Ditto.
3740 (emul_read_string): Ditto.
3742 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3744 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3745 emul_generic (emul_blr_instruction): Use a real blr instruction to
3746 return from a client service call.
3748 * emul_chirp.c (services): Add all OpenBoot services to table.
3750 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3751 (emul_chirp_create) : Use names instead of numbers for
3752 instructions being stored in memory.
3754 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3756 * Makefile.in (maintainer-clean): Remove .log, core and *.core
