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

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

573 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
575 Make the simulator compatible with the MPC750. It would be nicer
576 to make this a real multi-sim, but that's more work than we have
578 * emul_generic.c (emul_add_tree_options): Only require strict
579 alignment if it was explicitly requested at configuration time.
580 Don't make it the default for little-endian machines.
581 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
582 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
583 THRM2, THRM3): Plop in the MPC750 SPR registers.
584 (DABR): This is weird. This was HID5, but the PPC spec says this
585 should be DABR; why did some random processor use it for something
586 else? The HID5 entry dates back to the original checkin of the
587 simulator code in 1995, so remove it.
588 * sim_calls.c (register_names): Delete this; since the user can
589 now change GDB's list of register names dynamically, we can't
590 pretend there's a static mapping here.
591 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
592 function to get the register name. That ought to be accurate.
593 However, we're changing a compile-time dependency (using the
594 REGISTER_NAMES macro) into a link- and run-time dependency
595 (calling REGISTER_NAME, which happens to be a function call on the
598 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

1071 determine the simulation speed by looking at the number of elapsed
1072 ticks recorded by the event queue.
1074 * psim.c (psim_write_register, psim_read_register): Force the cpu
1075 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1076 next cpu would be zero any way.
1078 * mon.c (mon_print_info): If possible, print the system cycle
1079 performance. This is an indication of the number of instructions
1082 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1084 * The code to allow an event queue to be updated during a signal
1085 was missing. For main.c, a cntrl-c simulation termination wasn't
1088 * The simulation would not correctly restart if an event requested
1089 that the simulation be halted.
1091 * psim.c (psim_options): Add hack to -i option to optionally
1092 include a level vis -i2.
1093 (psim_usage): Document.
1095 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

1112 * gen-idecode.c (print_run_until_stop_body): Call
1113 event_queue_process_events to clear possibly pending events before

1141 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1142 to be initialized independant of the rest of the simulation
1143 initalization. Otherwize a trace option explictly set from gdb
1144 could be overridden by hw_trace.
1146 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1148 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1149 debug.c. It could be much simpler.

1197 output expressions in idecode.h file.
1199 * gen-icache.c (print_icache_body): Output them here.

1208 * The code that put values in and extracted values from the cache
1209 was too compilicated. The cache table did not allow values to be
1210 computed from cache entries. #defines could only be used when a
1211 cache was present, remove the restriction.
1213 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1214 scratch variable is defined when a cache entry is beinf
1215 filled. Change the definition of a COMPUTE variable to be defined
1216 when the cache entry is being used.
1217 * gen-icache.c: Update.
1219 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1232 * igen.c (main): Change 'R' option so that it does not force the
1235 * configure.in (enable-sim-icache): Clarify description. Make
1236 #define one of the defaults regardless of the cache. Probably
1237 should revamp and add a separate option.

3688 * device.c (device_interrupt_ack) : Delete old
3690 * device_table.c (unimp_*) : Update to match
3692 * device_table.c (icu_io_write_buffer_callback) : Update to use
3694 * device_table.c (icu_interrupt_event_callback) : Ditto
3696 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3698 * device.c (external_to_device) : New function that provides a
3699 standard mapping between a devices internal representation (a
3700 pointer) and its external (or what is passed to a client)
3701 representation (a phandle). Implement using the cap object
3702 attached to the root node.
3704 * device.c (device_to_external) : Ditto
3705 * device.c (external_to_device_instance) : Ditto but for ihandle
3706 and device instance.
3707 * device.c (device_instance_to_external) : Ditto
3709 * Makefile (device.o): Add dependency on cap.
3711 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3712 needing to translate between internal and external representations
3713 changed to use the external_to_device et.al. device operations.
3714 * emul_chirp.c (chirp_emul_*) : Ditto
3716 * Makefile (emul_chirp.o): Remove dependency on cap
3718 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3720 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3721 on OpenBoot note section.
3723 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3725 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3726 read/write calls for buffer transfers. This will cause a fault to
3727 occure if the transfer fails. CHRP catches the fault while the
3728 others suffer the consequences.
3729 (emul_read_buffer): Ditto.
3730 (emul_write_word): Ditto.
3731 (emul_read_word): Ditto.
3732 (emul_read_string): Ditto.
3734 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3736 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3737 emul_generic (emul_blr_instruction): Use a real blr instruction to
3738 return from a client service call.
3740 * emul_chirp.c (services): Add all OpenBoot services to table.
3742 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3743 (emul_chirp_create) : Use names instead of numbers for
3744 instructions being stored in memory.
3746 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3748 * Makefile.in (maintainer-clean): Remove .log, core and *.core
