529 open syscall to the numbers supported by the host.
531 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
533 * sim-endian.h: Don't have parameters on macro definitions which
534 are simply renaming functions, to permit use of XCONCAT2 in both
535 the macro name and the arguments in a use of such a definition.
537 2000-11-15 Jim Blandy <jimb@redhat.com>
539 * sim_calls.c: Doc fix.
540 (sim_fetch_register, sim_store_register): Call

575 1999-05-08 Felix Lee <flee@cygnus.com>
577 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
578 * configure: Regenerated to track ../common/aclocal.m4 changes.
580 1999-04-02 Keith Seitz <keiths@cygnus.com>
582 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
583 the frequency at which the poll_quit callback is called.

586 after the specified POLL_QUIT_INTERVAL.
588 1999-02-22 Jim Lemke <jlemke@cygnus.com>
590 * dc-complex: Force expansion on all bits of field BO.
591 Previously, the least-significant (prediction) bit was ignored.
592 * ppc-instructions (conditional branches): Implement mpc860c0 option.

598 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
600 Make the simulator compatible with the MPC750. It would be nicer
601 to make this a real multi-sim, but that's more work than we have
603 * emul_generic.c (emul_add_tree_options): Only require strict
604 alignment if it was explicitly requested at configuration time.
605 Don't make it the default for little-endian machines.
606 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
607 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
608 THRM2, THRM3): Plop in the MPC750 SPR registers.
609 (DABR): This is weird. This was HID5, but the PPC spec says this
610 should be DABR; why did some random processor use it for something
611 else? The HID5 entry dates back to the original checkin of the
612 simulator code in 1995, so remove it.
613 * sim_calls.c (register_names): Delete this; since the user can
614 now change GDB's list of register names dynamically, we can't
615 pretend there's a static mapping here.
616 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
617 function to get the register name. That ought to be accurate.
618 However, we're changing a compile-time dependency (using the
619 REGISTER_NAMES macro) into a link- and run-time dependency
620 (calling REGISTER_NAME, which happens to be a function call on the
623 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

1032 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1033 works for normal and boolean table entries.
1035 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
1036 valid. Handle this just like *_{read,write}_register now handles

1054 entry code so that it involves a mask + test instead of shift +
1055 shift + mask + test.
1057 * gen-idecode.c: Correct generated igen body so that it no drops
1058 or doubles clock interrupts.
1061 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1063 * Makefile.in (BUILT_SRC_WO_CONFIG): Change targ-vals.* to

1093 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1095 * When performance monitoring is disabled, it is still possible to
1096 determine the simulation speed by looking at the number of elapsed
1097 ticks recorded by the event queue.
1099 * psim.c (psim_write_register, psim_read_register): Force the cpu
1100 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1101 next cpu would be zero any way.
1103 * mon.c (mon_print_info): If possible, print the system cycle
1104 performance. This is an indication of the number of instructions
1107 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1109 * The code to allow an event queue to be updated during a signal
1110 was missing. For main.c, a cntrl-c simulation termination wasn't
1113 * The simulation would not correctly restart if an event requested
1114 that the simulation be halted.
1116 * psim.c (psim_options): Add hack to -i option to optionally
1117 include a level vis -i2.
1118 (psim_usage): Document.
1120 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

1134 (event_queue_tick): Check that processing isn't still being
1137 * gen-idecode.c (print_run_until_stop_body): Call
1138 event_queue_process_events to clear possibly pending events before
1139 starting a simulation run. Re-arange main loop so that simulator
1140 is correctly restarted when an event halts the simulation.
1142 * psim.c (psim_halt): Handle an event halting the simulation.
1143 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1146 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1148 * ppc-opcode-complex: Correct typo - was expanding ORA instead of

1166 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1167 to be initialized independant of the rest of the simulation
1168 initalization. Otherwize a trace option explictly set from gdb
1169 could be overridden by hw_trace.
1171 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1173 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1174 debug.c. It could be much simpler.

1216 the form <name>_is_<const> where it is a boolean field, generate
1217 the result of the expression instead of the expression its self.

1222 output expressions in idecode.h file.
1224 * gen-icache.c (print_icache_body): Output them here.

1233 * The code that put values in and extracted values from the cache
1234 was too compilicated. The cache table did not allow values to be
1235 computed from cache entries. #defines could only be used when a
1236 cache was present, remove the restriction.
1238 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1239 scratch variable is defined when a cache entry is beinf
1240 filled. Change the definition of a COMPUTE variable to be defined
1241 when the cache entry is being used.
1242 * gen-icache.c: Update.
1244 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1257 * igen.c (main): Change 'R' option so that it does not force the
1260 * configure.in (enable-sim-icache): Clarify description. Make
1261 #define one of the defaults regardless of the cache. Probably
1262 should revamp and add a separate option.

3695 * device.c (attach_device_interrupt_edge): New. Interrupt model
3696 did not allow interrupts to be wired up as a general net (edges).
3697 Re-implement so that interrupt events can be passed to multiple
3698 controllers and interrupt controllers can further propogate
3701 * device.c (attach_device_interrupt_edge) : New, Ditto
3702 * device.c (detach_device_interrupt_edge) : New, Ditto

3704 * device.c (device_interrupt_event) : New, Ditto
3705 * device.c (device_interrupt_attach) : New, Ditto
3706 * device.c (device_interrupt_detach) : New, Ditto
3707 * device.c (device_child_interrupt_attach) : New, Ditto
3708 * device.c (device_child_interrupt_detach) : New, Ditto
3710 * device.c (device_attach_interrupt) : Delete old
3711 * device.c (device_detach_interrupt) : Delete old
3712 * device.c (device_interrupt) : Delete old
3713 * device.c (device_interrupt_ack) : Delete old
3715 * device_table.c (unimp_*) : Update to match
3717 * device_table.c (icu_io_write_buffer_callback) : Update to use
3719 * device_table.c (icu_interrupt_event_callback) : Ditto
3721 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3723 * device.c (external_to_device) : New function that provides a
3724 standard mapping between a devices internal representation (a
3725 pointer) and its external (or what is passed to a client)
3726 representation (a phandle). Implement using the cap object
3727 attached to the root node.
3729 * device.c (device_to_external) : Ditto
3730 * device.c (external_to_device_instance) : Ditto but for ihandle
3731 and device instance.
3732 * device.c (device_instance_to_external) : Ditto
3734 * Makefile (device.o): Add dependency on cap.
3736 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3737 needing to translate between internal and external representations
3738 changed to use the external_to_device et.al. device operations.
3739 * emul_chirp.c (chirp_emul_*) : Ditto
3741 * Makefile (emul_chirp.o): Remove dependency on cap
3743 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3745 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3746 on OpenBoot note section.
3748 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3750 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3751 read/write calls for buffer transfers. This will cause a fault to
3752 occure if the transfer fails. CHRP catches the fault while the
3753 others suffer the consequences.
3754 (emul_read_buffer): Ditto.
3755 (emul_write_word): Ditto.
3756 (emul_read_word): Ditto.
3757 (emul_read_string): Ditto.
3759 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3761 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3762 emul_generic (emul_blr_instruction): Use a real blr instruction to
3763 return from a client service call.
3765 * emul_chirp.c (services): Add all OpenBoot services to table.
3767 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3768 (emul_chirp_create) : Use names instead of numbers for
3769 instructions being stored in memory.
3771 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3773 * Makefile.in (maintainer-clean): Remove .log, core and *.core
3774 (From NetBSD) files.
