517 open syscall to the numbers supported by the host.
519 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
521 * sim-endian.h: Don't have parameters on macro definitions which
522 are simply renaming functions, to permit use of XCONCAT2 in both
523 the macro name and the arguments in a use of such a definition.
525 2000-11-15 Jim Blandy <jimb@redhat.com>
527 * sim_calls.c: Doc fix.
528 (sim_fetch_register, sim_store_register): Call

557 the exponent when denormalizing.
559 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>

563 1999-05-08 Felix Lee <flee@cygnus.com>
565 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
566 * configure: Regenerated to track ../common/aclocal.m4 changes.
568 1999-04-02 Keith Seitz <keiths@cygnus.com>
570 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
571 the frequency at which the poll_quit callback is called.
572 (poll_quit_count): New global.
573 (sim_io_poll_quit): Only call the poll_quit callback
574 after the specified POLL_QUIT_INTERVAL.
576 1999-02-22 Jim Lemke <jlemke@cygnus.com>
578 * dc-complex: Force expansion on all bits of field BO.
579 Previously, the least-significant (prediction) bit was ignored.
580 * ppc-instructions (conditional branches): Implement mpc860c0 option.
581 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
582 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

586 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
588 Make the simulator compatible with the MPC750. It would be nicer
589 to make this a real multi-sim, but that's more work than we have
591 * emul_generic.c (emul_add_tree_options): Only require strict
592 alignment if it was explicitly requested at configuration time.
593 Don't make it the default for little-endian machines.
594 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
595 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
596 THRM2, THRM3): Plop in the MPC750 SPR registers.
597 (DABR): This is weird. This was HID5, but the PPC spec says this
598 should be DABR; why did some random processor use it for something
599 else? The HID5 entry dates back to the original checkin of the
600 simulator code in 1995, so remove it.
601 * sim_calls.c (register_names): Delete this; since the user can
602 now change GDB's list of register names dynamically, we can't
603 pretend there's a static mapping here.
604 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
605 function to get the register name. That ought to be accurate.
606 However, we're changing a compile-time dependency (using the
607 REGISTER_NAMES macro) into a link- and run-time dependency
608 (calling REGISTER_NAME, which happens to be a function call on the
611 1999-01-22 Jim Lemke <jlemke@cygnus.com>

618 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
620 1998-12-01 Ken Raeburn <raeburn@cygnus.com>

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

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

1084 determine the simulation speed by looking at the number of elapsed
1085 ticks recorded by the event queue.
1087 * psim.c (psim_write_register, psim_read_register): Force the cpu
1088 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1089 next cpu would be zero any way.
1091 * mon.c (mon_print_info): If possible, print the system cycle
1092 performance. This is an indication of the number of instructions
1095 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1097 * The code to allow an event queue to be updated during a signal
1098 was missing. For main.c, a cntrl-c simulation termination wasn't
1101 * The simulation would not correctly restart if an event requested
1102 that the simulation be halted.
1104 * psim.c (psim_options): Add hack to -i option to optionally
1105 include a level vis -i2.
1106 (psim_usage): Document.

1125 * gen-idecode.c (print_run_until_stop_body): Call
1126 event_queue_process_events to clear possibly pending events before

1154 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1155 to be initialized independant of the rest of the simulation
1156 initalization. Otherwize a trace option explictly set from gdb
1157 could be overridden by hw_trace.
1159 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1161 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1162 debug.c. It could be much simpler.

1204 the form <name>_is_<const> where it is a boolean field, generate
1205 the result of the expression instead of the expression its self.

1221 * The code that put values in and extracted values from the cache
1222 was too compilicated. The cache table did not allow values to be
1223 computed from cache entries. #defines could only be used when a
1224 cache was present, remove the restriction.
1226 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1227 scratch variable is defined when a cache entry is beinf
1228 filled. Change the definition of a COMPUTE variable to be defined
1229 when the cache entry is being used.
1230 * gen-icache.c: Update.
1232 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1248 * configure.in (enable-sim-icache): Clarify description. Make
1249 #define one of the defaults regardless of the cache. Probably
1250 should revamp and add a separate option.

3685 Re-implement so that interrupt events can be passed to multiple
3686 controllers and interrupt controllers can further propogate
3689 * device.c (attach_device_interrupt_edge) : New, Ditto
3690 * device.c (detach_device_interrupt_edge) : New, Ditto
3691 * device.c (clean_device_interrupt_edges) : New, Ditto
3692 * device.c (device_interrupt_event) : New, Ditto
3693 * device.c (device_interrupt_attach) : New, Ditto
3694 * device.c (device_interrupt_detach) : New, Ditto
3695 * device.c (device_child_interrupt_attach) : New, Ditto
3696 * device.c (device_child_interrupt_detach) : New, Ditto
3698 * device.c (device_attach_interrupt) : Delete old
3699 * device.c (device_detach_interrupt) : Delete old
3700 * device.c (device_interrupt) : Delete old
3701 * device.c (device_interrupt_ack) : Delete old
3703 * device_table.c (unimp_*) : Update to match
3705 * device_table.c (icu_io_write_buffer_callback) : Update to use
3707 * device_table.c (icu_interrupt_event_callback) : Ditto
3709 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3711 * device.c (external_to_device) : New function that provides a
3712 standard mapping between a devices internal representation (a
3713 pointer) and its external (or what is passed to a client)
3714 representation (a phandle). Implement using the cap object
3715 attached to the root node.
3717 * device.c (device_to_external) : Ditto
3718 * device.c (external_to_device_instance) : Ditto but for ihandle
3719 and device instance.
3720 * device.c (device_instance_to_external) : Ditto
3722 * Makefile (device.o): Add dependency on cap.
3724 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3725 needing to translate between internal and external representations
3726 changed to use the external_to_device et.al. device operations.
3727 * emul_chirp.c (chirp_emul_*) : Ditto
3729 * Makefile (emul_chirp.o): Remove dependency on cap
3731 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3733 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3734 on OpenBoot note section.
3736 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3738 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3739 read/write calls for buffer transfers. This will cause a fault to
3740 occure if the transfer fails. CHRP catches the fault while the
3741 others suffer the consequences.
3742 (emul_read_buffer): Ditto.
3743 (emul_write_word): Ditto.
3744 (emul_read_word): Ditto.
3745 (emul_read_string): Ditto.
3747 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3749 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3750 emul_generic (emul_blr_instruction): Use a real blr instruction to
3751 return from a client service call.
3753 * emul_chirp.c (services): Add all OpenBoot services to table.
3755 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3756 (emul_chirp_create) : Use names instead of numbers for
3757 instructions being stored in memory.
3759 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3761 * Makefile.in (maintainer-clean): Remove .log, core and *.core
3762 (From NetBSD) files.
