502 open syscall to the numbers supported by the host.
504 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
506 * sim-endian.h: Don't have parameters on macro definitions which
507 are simply renaming functions, to permit use of XCONCAT2 in both
508 the macro name and the arguments in a use of such a definition.
510 2000-11-15 Jim Blandy <jimb@redhat.com>
512 * sim_calls.c: Doc fix.
513 (sim_fetch_register, sim_store_register): Call
514 gdbarch_register_name directly, instead of going through

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

541 * ppc-instructions (Disabled_Exponent_Underflow): Increment
542 the exponent when denormalizing.
544 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
546 * configure: Regenerated to track ../common/aclocal.m4 changes.
548 1999-05-08 Felix Lee <flee@cygnus.com>
550 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
551 * configure: Regenerated to track ../common/aclocal.m4 changes.
553 1999-04-02 Keith Seitz <keiths@cygnus.com>
555 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
556 the frequency at which the poll_quit callback is called.
557 (poll_quit_count): New global.
558 (sim_io_poll_quit): Only call the poll_quit callback
559 after the specified POLL_QUIT_INTERVAL.
561 1999-02-22 Jim Lemke <jlemke@cygnus.com>
563 * dc-complex: Force expansion on all bits of field BO.
564 Previously, the least-significant (prediction) bit was ignored.
565 * ppc-instructions (conditional branches): Implement mpc860c0 option.
566 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
567 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

569 * interrupts.c (program_interrupt): Added handling for above interrupt.
571 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
573 Make the simulator compatible with the MPC750. It would be nicer
574 to make this a real multi-sim, but that's more work than we have
576 * emul_generic.c (emul_add_tree_options): Only require strict
577 alignment if it was explicitly requested at configuration time.
578 Don't make it the default for little-endian machines.
579 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
580 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
581 THRM2, THRM3): Plop in the MPC750 SPR registers.
582 (DABR): This is weird. This was HID5, but the PPC spec says this
583 should be DABR; why did some random processor use it for something
584 else? The HID5 entry dates back to the original checkin of the
585 simulator code in 1995, so remove it.
586 * sim_calls.c (register_names): Delete this; since the user can
587 now change GDB's list of register names dynamically, we can't
588 pretend there's a static mapping here.
589 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
590 function to get the register name. That ought to be accurate.
591 However, we're changing a compile-time dependency (using the
592 REGISTER_NAMES macro) into a link- and run-time dependency
593 (calling REGISTER_NAME, which happens to be a function call on the
596 1999-01-22 Jim Lemke <jlemke@cygnus.com>

603 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
605 1998-12-01 Ken Raeburn <raeburn@cygnus.com>

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

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

1069 determine the simulation speed by looking at the number of elapsed
1070 ticks recorded by the event queue.
1072 * psim.c (psim_write_register, psim_read_register): Force the cpu
1073 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1074 next cpu would be zero any way.
1076 * mon.c (mon_print_info): If possible, print the system cycle
1077 performance. This is an indication of the number of instructions
1080 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1082 * The code to allow an event queue to be updated during a signal
1083 was missing. For main.c, a cntrl-c simulation termination wasn't
1086 * The simulation would not correctly restart if an event requested
1087 that the simulation be halted.
1089 * psim.c (psim_options): Add hack to -i option to optionally
1090 include a level vis -i2.
1091 (psim_usage): Document.
1093 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

1110 * gen-idecode.c (print_run_until_stop_body): Call
1111 event_queue_process_events to clear possibly pending events before

1139 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1140 to be initialized independant of the rest of the simulation
1141 initalization. Otherwize a trace option explictly set from gdb
1142 could be overridden by hw_trace.
1144 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1146 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1147 debug.c. It could be much simpler.

1195 output expressions in idecode.h file.
1197 * gen-icache.c (print_icache_body): Output them here.

1206 * The code that put values in and extracted values from the cache
1207 was too compilicated. The cache table did not allow values to be
1208 computed from cache entries. #defines could only be used when a
1209 cache was present, remove the restriction.
1211 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1212 scratch variable is defined when a cache entry is beinf
1213 filled. Change the definition of a COMPUTE variable to be defined
1214 when the cache entry is being used.
1215 * gen-icache.c: Update.
1217 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1230 * igen.c (main): Change 'R' option so that it does not force the
1233 * configure.in (enable-sim-icache): Clarify description. Make
1234 #define one of the defaults regardless of the cache. Probably
1235 should revamp and add a separate option.

3686 * device.c (device_interrupt_ack) : Delete old
3688 * device_table.c (unimp_*) : Update to match
3690 * device_table.c (icu_io_write_buffer_callback) : Update to use
3692 * device_table.c (icu_interrupt_event_callback) : Ditto
3694 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3696 * device.c (external_to_device) : New function that provides a
3697 standard mapping between a devices internal representation (a
3698 pointer) and its external (or what is passed to a client)
3699 representation (a phandle). Implement using the cap object
3700 attached to the root node.
3702 * device.c (device_to_external) : Ditto
3703 * device.c (external_to_device_instance) : Ditto but for ihandle
3704 and device instance.
3705 * device.c (device_instance_to_external) : Ditto
3707 * Makefile (device.o): Add dependency on cap.
3709 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3710 needing to translate between internal and external representations
3711 changed to use the external_to_device et.al. device operations.
3712 * emul_chirp.c (chirp_emul_*) : Ditto
3714 * Makefile (emul_chirp.o): Remove dependency on cap
3716 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3718 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3719 on OpenBoot note section.
3721 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3723 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3724 read/write calls for buffer transfers. This will cause a fault to
3725 occure if the transfer fails. CHRP catches the fault while the
3726 others suffer the consequences.
3727 (emul_read_buffer): Ditto.
3728 (emul_write_word): Ditto.
3729 (emul_read_word): Ditto.
3730 (emul_read_string): Ditto.
3732 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3734 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3735 emul_generic (emul_blr_instruction): Use a real blr instruction to
3736 return from a client service call.
3738 * emul_chirp.c (services): Add all OpenBoot services to table.
3740 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3741 (emul_chirp_create) : Use names instead of numbers for
3742 instructions being stored in memory.
3744 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3746 * Makefile.in (maintainer-clean): Remove .log, core and *.core
