521 open syscall to the numbers supported by the host.
523 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
525 * sim-endian.h: Don't have parameters on macro definitions which
526 are simply renaming functions, to permit use of XCONCAT2 in both
527 the macro name and the arguments in a use of such a definition.
529 2000-11-15 Jim Blandy <jimb@redhat.com>
531 * sim_calls.c: Doc fix.
532 (sim_fetch_register, sim_store_register): Call

561 the exponent when denormalizing.
563 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
565 * configure: Regenerated to track ../common/aclocal.m4 changes.
567 1999-05-08 Felix Lee <flee@cygnus.com>
569 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
570 * configure: Regenerated to track ../common/aclocal.m4 changes.
572 1999-04-02 Keith Seitz <keiths@cygnus.com>
574 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
575 the frequency at which the poll_quit callback is called.
576 (poll_quit_count): New global.
577 (sim_io_poll_quit): Only call the poll_quit callback
578 after the specified POLL_QUIT_INTERVAL.
580 1999-02-22 Jim Lemke <jlemke@cygnus.com>
582 * dc-complex: Force expansion on all bits of field BO.
583 Previously, the least-significant (prediction) bit was ignored.
584 * ppc-instructions (conditional branches): Implement mpc860c0 option.
585 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
586 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

590 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
592 Make the simulator compatible with the MPC750. It would be nicer
593 to make this a real multi-sim, but that's more work than we have
595 * emul_generic.c (emul_add_tree_options): Only require strict
596 alignment if it was explicitly requested at configuration time.
597 Don't make it the default for little-endian machines.
598 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
599 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
600 THRM2, THRM3): Plop in the MPC750 SPR registers.
601 (DABR): This is weird. This was HID5, but the PPC spec says this
602 should be DABR; why did some random processor use it for something
603 else? The HID5 entry dates back to the original checkin of the
604 simulator code in 1995, so remove it.
605 * sim_calls.c (register_names): Delete this; since the user can
606 now change GDB's list of register names dynamically, we can't
607 pretend there's a static mapping here.
608 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
609 function to get the register name. That ought to be accurate.
610 However, we're changing a compile-time dependency (using the
611 REGISTER_NAMES macro) into a link- and run-time dependency
612 (calling REGISTER_NAME, which happens to be a function call on the
615 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

1088 determine the simulation speed by looking at the number of elapsed
1089 ticks recorded by the event queue.
1091 * psim.c (psim_write_register, psim_read_register): Force the cpu
1092 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1093 next cpu would be zero any way.
1095 * mon.c (mon_print_info): If possible, print the system cycle
1096 performance. This is an indication of the number of instructions
1099 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1101 * The code to allow an event queue to be updated during a signal
1102 was missing. For main.c, a cntrl-c simulation termination wasn't
1105 * The simulation would not correctly restart if an event requested
1106 that the simulation be halted.
1108 * psim.c (psim_options): Add hack to -i option to optionally
1109 include a level vis -i2.
1110 (psim_usage): Document.

1129 * gen-idecode.c (print_run_until_stop_body): Call
1130 event_queue_process_events to clear possibly pending events before

1158 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1159 to be initialized independant of the rest of the simulation
1160 initalization. Otherwize a trace option explictly set from gdb
1161 could be overridden by hw_trace.
1163 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1165 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1166 debug.c. It could be much simpler.

1225 * The code that put values in and extracted values from the cache
1226 was too compilicated. The cache table did not allow values to be
1227 computed from cache entries. #defines could only be used when a
1228 cache was present, remove the restriction.
1230 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1231 scratch variable is defined when a cache entry is beinf
1232 filled. Change the definition of a COMPUTE variable to be defined
1233 when the cache entry is being used.
1234 * gen-icache.c: Update.
1236 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1252 * configure.in (enable-sim-icache): Clarify description. Make
1253 #define one of the defaults regardless of the cache. Probably
1254 should revamp and add a separate option.

3689 Re-implement so that interrupt events can be passed to multiple
3690 controllers and interrupt controllers can further propogate
3693 * device.c (attach_device_interrupt_edge) : New, Ditto
3694 * device.c (detach_device_interrupt_edge) : New, Ditto
3695 * device.c (clean_device_interrupt_edges) : New, Ditto
3696 * device.c (device_interrupt_event) : New, Ditto
3697 * device.c (device_interrupt_attach) : New, Ditto
3698 * device.c (device_interrupt_detach) : New, Ditto
3699 * device.c (device_child_interrupt_attach) : New, Ditto
3700 * device.c (device_child_interrupt_detach) : New, Ditto
3702 * device.c (device_attach_interrupt) : Delete old
3703 * device.c (device_detach_interrupt) : Delete old
3704 * device.c (device_interrupt) : Delete old
3705 * device.c (device_interrupt_ack) : Delete old
3707 * device_table.c (unimp_*) : Update to match
3709 * device_table.c (icu_io_write_buffer_callback) : Update to use
3711 * device_table.c (icu_interrupt_event_callback) : Ditto
3713 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3715 * device.c (external_to_device) : New function that provides a
3716 standard mapping between a devices internal representation (a
3717 pointer) and its external (or what is passed to a client)
3718 representation (a phandle). Implement using the cap object
3719 attached to the root node.
3721 * device.c (device_to_external) : Ditto
3722 * device.c (external_to_device_instance) : Ditto but for ihandle
3723 and device instance.
3724 * device.c (device_instance_to_external) : Ditto
3726 * Makefile (device.o): Add dependency on cap.
3728 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3729 needing to translate between internal and external representations
3730 changed to use the external_to_device et.al. device operations.
3731 * emul_chirp.c (chirp_emul_*) : Ditto
3733 * Makefile (emul_chirp.o): Remove dependency on cap
3735 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3737 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3738 on OpenBoot note section.
3740 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3742 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3743 read/write calls for buffer transfers. This will cause a fault to
3744 occure if the transfer fails. CHRP catches the fault while the
3745 others suffer the consequences.
3746 (emul_read_buffer): Ditto.
3747 (emul_write_word): Ditto.
3748 (emul_read_word): Ditto.
3749 (emul_read_string): Ditto.
3751 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3753 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3754 emul_generic (emul_blr_instruction): Use a real blr instruction to
3755 return from a client service call.
3757 * emul_chirp.c (services): Add all OpenBoot services to table.
3759 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3760 (emul_chirp_create) : Use names instead of numbers for
3761 instructions being stored in memory.
3763 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3765 * Makefile.in (maintainer-clean): Remove .log, core and *.core
3766 (From NetBSD) files.
