572 open syscall to the numbers supported by the host.
574 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
576 * sim-endian.h: Don't have parameters on macro definitions which
577 are simply renaming functions, to permit use of XCONCAT2 in both
578 the macro name and the arguments in a use of such a definition.
580 2000-11-15 Jim Blandy <jimb@redhat.com>
582 * sim_calls.c: Doc fix.
583 (sim_fetch_register, sim_store_register): Call

618 1999-05-08 Felix Lee <flee@cygnus.com>
620 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
621 * configure: Regenerated to track ../common/aclocal.m4 changes.
623 1999-04-02 Keith Seitz <keiths@cygnus.com>
625 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
626 the frequency at which the poll_quit callback is called.
627 (poll_quit_count): New global.
628 (sim_io_poll_quit): Only call the poll_quit callback
629 after the specified POLL_QUIT_INTERVAL.
631 1999-02-22 Jim Lemke <jlemke@cygnus.com>
633 * dc-complex: Force expansion on all bits of field BO.
634 Previously, the least-significant (prediction) bit was ignored.
635 * ppc-instructions (conditional branches): Implement mpc860c0 option.
636 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
637 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

639 * interrupts.c (program_interrupt): Added handling for above interrupt.
641 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
643 Make the simulator compatible with the MPC750. It would be nicer
644 to make this a real multi-sim, but that's more work than we have
646 * emul_generic.c (emul_add_tree_options): Only require strict
647 alignment if it was explicitly requested at configuration time.
648 Don't make it the default for little-endian machines.
649 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
650 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
651 THRM2, THRM3): Plop in the MPC750 SPR registers.
652 (DABR): This is weird. This was HID5, but the PPC spec says this
653 should be DABR; why did some random processor use it for something
654 else? The HID5 entry dates back to the original checkin of the
655 simulator code in 1995, so remove it.
656 * sim_calls.c (register_names): Delete this; since the user can
657 now change GDB's list of register names dynamically, we can't
658 pretend there's a static mapping here.
659 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
660 function to get the register name. That ought to be accurate.
661 However, we're changing a compile-time dependency (using the
662 REGISTER_NAMES macro) into a link- and run-time dependency
663 (calling REGISTER_NAME, which happens to be a function call on the
666 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

1100 * gen-idecode.c: Correct generated igen body so that it no drops
1101 or doubles clock interrupts.
1104 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1106 * Makefile.in (BUILT_SRC_WO_CONFIG): Change targ-vals.* to

1139 determine the simulation speed by looking at the number of elapsed
1140 ticks recorded by the event queue.
1142 * psim.c (psim_write_register, psim_read_register): Force the cpu
1143 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1144 next cpu would be zero any way.
1146 * mon.c (mon_print_info): If possible, print the system cycle
1147 performance. This is an indication of the number of instructions
1150 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1152 * The code to allow an event queue to be updated during a signal
1153 was missing. For main.c, a cntrl-c simulation termination wasn't
1156 * The simulation would not correctly restart if an event requested
1157 that the simulation be halted.
1159 * psim.c (psim_options): Add hack to -i option to optionally
1160 include a level vis -i2.
1161 (psim_usage): Document.

1180 * gen-idecode.c (print_run_until_stop_body): Call
1181 event_queue_process_events to clear possibly pending events before

1209 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1210 to be initialized independant of the rest of the simulation
1211 initalization. Otherwize a trace option explictly set from gdb
1212 could be overridden by hw_trace.
1214 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1216 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1217 debug.c. It could be much simpler.
1219 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1259 the form <name>_is_<const> where it is a boolean field, generate
1260 the result of the expression instead of the expression its self.

1276 * The code that put values in and extracted values from the cache
1277 was too compilicated. The cache table did not allow values to be
1278 computed from cache entries. #defines could only be used when a
1279 cache was present, remove the restriction.
1281 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1282 scratch variable is defined when a cache entry is beinf
1283 filled. Change the definition of a COMPUTE variable to be defined
1284 when the cache entry is being used.
1285 * gen-icache.c: Update.
1287 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1300 * igen.c (main): Change 'R' option so that it does not force the
1303 * configure.in (enable-sim-icache): Clarify description. Make
1304 #define one of the defaults regardless of the cache. Probably
1305 should revamp and add a separate option.

3700 * device_tree.c (trace_*): New device node, its properties are
3701 used to set the value of the trace options. Init this device (in
3702 psim_options) when ever the options are updated.
3704 Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
3706 * debug.h: Add trace_print_info, trace_print_device_tree and
3707 trace_dump_device_tree. The first is a replacement for the
3708 variable `print_info' found in main.c and sim_calls.c. The latter
3709 two enable the dumping of the entire device tree.
3711 * debug.c: Add to trace_description table.
3713 * main.c (main): Use above trace instead of local variable
3714 * sim_calls.c (sim_close): Ditto
3716 * device.c (device_tree_print_device): New. Prints the device
3717 tree in a format that is consistent with what can be parsed by the
3718 device tree load from file code.
3720 * psim.c (psim_create): Dump device tree if enabled. If nump
3721 selected, exit psim immediatly.
3723 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
3725 * corefile-n.h (core_map_read_N): When mapping from an address to
3726 a device, do not subtract the devices base. The device its self
3727 can do this. Brings the behavour into line with OpenBoot.
3728 * corefile-n.h (core_map_write_N): Ditto
3729 * corefile.c (core_map_read_buffer): Ditto
3730 * corefile.c (core_map_write_buffer): Ditto
3732 * device_table.c (console_io_read_buffer_callback): Adjust to
3733 handle biased address.
3734 * device_table.c (console_io_write_buffer_callback): Ditto
3736 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
3738 * device.c (attach_device_interrupt_edge): New. Interrupt model
3739 did not allow interrupts to be wired up as a general net (edges).
3740 Re-implement so that interrupt events can be passed to multiple
3741 controllers and interrupt controllers can further propogate
3744 * device.c (attach_device_interrupt_edge) : New, Ditto
3745 * device.c (detach_device_interrupt_edge) : New, Ditto

3750 * device.c (device_child_interrupt_attach) : New, Ditto
3751 * device.c (device_child_interrupt_detach) : New, Ditto
3753 * device.c (device_attach_interrupt) : Delete old
3754 * device.c (device_detach_interrupt) : Delete old
3755 * device.c (device_interrupt) : Delete old
3756 * device.c (device_interrupt_ack) : Delete old
3758 * device_table.c (unimp_*) : Update to match
3760 * device_table.c (icu_io_write_buffer_callback) : Update to use
3762 * device_table.c (icu_interrupt_event_callback) : Ditto
3764 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3766 * device.c (external_to_device) : New function that provides a
3767 standard mapping between a devices internal representation (a
3768 pointer) and its external (or what is passed to a client)
3769 representation (a phandle). Implement using the cap object
3770 attached to the root node.
3772 * device.c (device_to_external) : Ditto
3773 * device.c (external_to_device_instance) : Ditto but for ihandle
3774 and device instance.
3775 * device.c (device_instance_to_external) : Ditto
3777 * Makefile (device.o): Add dependency on cap.
3779 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3780 needing to translate between internal and external representations
3781 changed to use the external_to_device et.al. device operations.
3782 * emul_chirp.c (chirp_emul_*) : Ditto
3784 * Makefile (emul_chirp.o): Remove dependency on cap
3786 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3788 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3789 on OpenBoot note section.
3791 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3793 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3794 read/write calls for buffer transfers. This will cause a fault to
3795 occure if the transfer fails. CHRP catches the fault while the
3796 others suffer the consequences.
3797 (emul_read_buffer): Ditto.
3798 (emul_write_word): Ditto.
3799 (emul_read_word): Ditto.
3800 (emul_read_string): Ditto.
3802 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3804 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3805 emul_generic (emul_blr_instruction): Use a real blr instruction to
3806 return from a client service call.
3808 * emul_chirp.c (services): Add all OpenBoot services to table.
3810 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3811 (emul_chirp_create) : Use names instead of numbers for
3812 instructions being stored in memory.
3814 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3816 * Makefile.in (maintainer-clean): Remove .log, core and *.core
3817 (From NetBSD) files.
