496 open syscall to the numbers supported by the host.
498 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
500 * sim-endian.h: Don't have parameters on macro definitions which
501 are simply renaming functions, to permit use of XCONCAT2 in both
502 the macro name and the arguments in a use of such a definition.
504 2000-11-15 Jim Blandy <jimb@redhat.com>
506 * sim_calls.c: Doc fix.
507 (sim_fetch_register, sim_store_register): Call
508 gdbarch_register_name directly, instead of going through
511 2000-10-24 Geoff Keating <geoffk@cygnus.com>

523 (update_time_from_event): Delete assertion that a negative
524 time_from_event implies an empty event queue.

535 * ppc-instructions (Disabled_Exponent_Underflow): Increment
536 the exponent when denormalizing.
538 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
540 * configure: Regenerated to track ../common/aclocal.m4 changes.
542 1999-05-08 Felix Lee <flee@cygnus.com>
544 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
545 * configure: Regenerated to track ../common/aclocal.m4 changes.
547 1999-04-02 Keith Seitz <keiths@cygnus.com>
549 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
550 the frequency at which the poll_quit callback is called.
551 (poll_quit_count): New global.
552 (sim_io_poll_quit): Only call the poll_quit callback
553 after the specified POLL_QUIT_INTERVAL.
555 1999-02-22 Jim Lemke <jlemke@cygnus.com>
557 * dc-complex: Force expansion on all bits of field BO.
558 Previously, the least-significant (prediction) bit was ignored.
559 * ppc-instructions (conditional branches): Implement mpc860c0 option.
560 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
561 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

565 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
567 Make the simulator compatible with the MPC750. It would be nicer
568 to make this a real multi-sim, but that's more work than we have
570 * emul_generic.c (emul_add_tree_options): Only require strict
571 alignment if it was explicitly requested at configuration time.
572 Don't make it the default for little-endian machines.
573 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
574 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
575 THRM2, THRM3): Plop in the MPC750 SPR registers.
576 (DABR): This is weird. This was HID5, but the PPC spec says this
577 should be DABR; why did some random processor use it for something
578 else? The HID5 entry dates back to the original checkin of the
579 simulator code in 1995, so remove it.
580 * sim_calls.c (register_names): Delete this; since the user can
581 now change GDB's list of register names dynamically, we can't
582 pretend there's a static mapping here.
583 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
584 function to get the register name. That ought to be accurate.
585 However, we're changing a compile-time dependency (using the
586 REGISTER_NAMES macro) into a link- and run-time dependency
587 (calling REGISTER_NAME, which happens to be a function call on the
590 1999-01-22 Jim Lemke <jlemke@cygnus.com>
592 * igen.c(gen_semantics_[ch]): setup/use of new option

596 psim.c(is_num - added, psim_options): Parse and init new option.
597 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
599 1998-12-01 Ken Raeburn <raeburn@cygnus.com>

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

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

999 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1000 works for normal and boolean table entries.
1002 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now

1024 * gen-idecode.c: Correct generated igen body so that it no drops
1025 or doubles clock interrupts.

1060 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1062 * When performance monitoring is disabled, it is still possible to
1063 determine the simulation speed by looking at the number of elapsed
1064 ticks recorded by the event queue.
1066 * psim.c (psim_write_register, psim_read_register): Force the cpu
1067 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1068 next cpu would be zero any way.
1070 * mon.c (mon_print_info): If possible, print the system cycle
1071 performance. This is an indication of the number of instructions
1074 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1076 * The code to allow an event queue to be updated during a signal
1077 was missing. For main.c, a cntrl-c simulation termination wasn't
1080 * The simulation would not correctly restart if an event requested
1081 that the simulation be halted.
1083 * psim.c (psim_options): Add hack to -i option to optionally
1084 include a level vis -i2.
1085 (psim_usage): Document.
1087 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

1104 * gen-idecode.c (print_run_until_stop_body): Call
1105 event_queue_process_events to clear possibly pending events before
1106 starting a simulation run. Re-arange main loop so that simulator
1107 is correctly restarted when an event halts the simulation.

1110 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1113 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1133 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1134 to be initialized independant of the rest of the simulation
1135 initalization. Otherwize a trace option explictly set from gdb
1136 could be overridden by hw_trace.
1138 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1140 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1141 debug.c. It could be much simpler.

1183 the form <name>_is_<const> where it is a boolean field, generate
1184 the result of the expression instead of the expression its self.

1189 output expressions in idecode.h file.
1191 * gen-icache.c (print_icache_body): Output them here.

1200 * The code that put values in and extracted values from the cache
1201 was too compilicated. The cache table did not allow values to be
1202 computed from cache entries. #defines could only be used when a
1203 cache was present, remove the restriction.
1205 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1206 scratch variable is defined when a cache entry is beinf
1207 filled. Change the definition of a COMPUTE variable to be defined
1208 when the cache entry is being used.
1209 * gen-icache.c: Update.
1211 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1224 * igen.c (main): Change 'R' option so that it does not force the
1227 * configure.in (enable-sim-icache): Clarify description. Make
1228 #define one of the defaults regardless of the cache. Probably
1229 should revamp and add a separate option.

3684 * device_table.c (icu_io_write_buffer_callback) : Update to use
3686 * device_table.c (icu_interrupt_event_callback) : Ditto
3688 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3690 * device.c (external_to_device) : New function that provides a
3691 standard mapping between a devices internal representation (a
3692 pointer) and its external (or what is passed to a client)
3693 representation (a phandle). Implement using the cap object
3694 attached to the root node.
3696 * device.c (device_to_external) : Ditto
3697 * device.c (external_to_device_instance) : Ditto but for ihandle
3698 and device instance.
3699 * device.c (device_instance_to_external) : Ditto
3701 * Makefile (device.o): Add dependency on cap.
3703 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3704 needing to translate between internal and external representations
3705 changed to use the external_to_device et.al. device operations.
3706 * emul_chirp.c (chirp_emul_*) : Ditto
3708 * Makefile (emul_chirp.o): Remove dependency on cap
3710 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3712 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3713 on OpenBoot note section.
3715 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3717 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3718 read/write calls for buffer transfers. This will cause a fault to
3719 occure if the transfer fails. CHRP catches the fault while the
3720 others suffer the consequences.
3721 (emul_read_buffer): Ditto.
3722 (emul_write_word): Ditto.
3723 (emul_read_word): Ditto.
3724 (emul_read_string): Ditto.
3726 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3728 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3729 emul_generic (emul_blr_instruction): Use a real blr instruction to
3730 return from a client service call.
3732 * emul_chirp.c (services): Add all OpenBoot services to table.
3734 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3735 (emul_chirp_create) : Use names instead of numbers for
3736 instructions being stored in memory.
3738 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3740 * Makefile.in (maintainer-clean): Remove .log, core and *.core
