577 open syscall to the numbers supported by the host.
579 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
581 * sim-endian.h: Don't have parameters on macro definitions which
582 are simply renaming functions, to permit use of XCONCAT2 in both
583 the macro name and the arguments in a use of such a definition.
585 2000-11-15 Jim Blandy <jimb@redhat.com>
587 * sim_calls.c: Doc fix.
588 (sim_fetch_register, sim_store_register): Call

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

646 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
648 Make the simulator compatible with the MPC750. It would be nicer
649 to make this a real multi-sim, but that's more work than we have
651 * emul_generic.c (emul_add_tree_options): Only require strict
652 alignment if it was explicitly requested at configuration time.
653 Don't make it the default for little-endian machines.
654 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
655 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
656 THRM2, THRM3): Plop in the MPC750 SPR registers.
657 (DABR): This is weird. This was HID5, but the PPC spec says this
658 should be DABR; why did some random processor use it for something
659 else? The HID5 entry dates back to the original checkin of the
660 simulator code in 1995, so remove it.
661 * sim_calls.c (register_names): Delete this; since the user can
662 now change GDB's list of register names dynamically, we can't
663 pretend there's a static mapping here.
664 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
665 function to get the register name. That ought to be accurate.
666 However, we're changing a compile-time dependency (using the
667 REGISTER_NAMES macro) into a link- and run-time dependency
668 (calling REGISTER_NAME, which happens to be a function call on the
671 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

1144 determine the simulation speed by looking at the number of elapsed
1145 ticks recorded by the event queue.
1147 * psim.c (psim_write_register, psim_read_register): Force the cpu
1148 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1149 next cpu would be zero any way.
1151 * mon.c (mon_print_info): If possible, print the system cycle
1152 performance. This is an indication of the number of instructions
1155 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1157 * The code to allow an event queue to be updated during a signal
1158 was missing. For main.c, a cntrl-c simulation termination wasn't
1161 * The simulation would not correctly restart if an event requested
1162 that the simulation be halted.
1164 * psim.c (psim_options): Add hack to -i option to optionally
1165 include a level vis -i2.
1166 (psim_usage): Document.

1185 * gen-idecode.c (print_run_until_stop_body): Call
1186 event_queue_process_events to clear possibly pending events before
1187 starting a simulation run. Re-arange main loop so that simulator
1188 is correctly restarted when an event halts the simulation.

1214 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1215 to be initialized independant of the rest of the simulation
1216 initalization. Otherwize a trace option explictly set from gdb
1217 could be overridden by hw_trace.
1219 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1221 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1222 debug.c. It could be much simpler.
1224 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1264 the form <name>_is_<const> where it is a boolean field, generate
1265 the result of the expression instead of the expression its self.

1281 * The code that put values in and extracted values from the cache
1282 was too compilicated. The cache table did not allow values to be
1283 computed from cache entries. #defines could only be used when a
1284 cache was present, remove the restriction.
1286 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1287 scratch variable is defined when a cache entry is beinf
1288 filled. Change the definition of a COMPUTE variable to be defined
1289 when the cache entry is being used.
1290 * gen-icache.c: Update.
1292 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1308 * configure.in (enable-sim-icache): Clarify description. Make
1309 #define one of the defaults regardless of the cache. Probably
1310 should revamp and add a separate option.

3698 * corefile.c (core_create, core_device_create): Adjust so that the
3699 core device is created earlier for psim_tree(). Core can later be
3702 * psim.c (psim_create): Update to handle above way of creating
3703 things. Extract all information from the device tree.
3705 * device_tree.c (trace_*): New device node, its properties are
3706 used to set the value of the trace options. Init this device (in
3707 psim_options) when ever the options are updated.
3709 Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
3711 * debug.h: Add trace_print_info, trace_print_device_tree and
3712 trace_dump_device_tree. The first is a replacement for the
3713 variable `print_info' found in main.c and sim_calls.c. The latter
3714 two enable the dumping of the entire device tree.
3716 * debug.c: Add to trace_description table.
3718 * main.c (main): Use above trace instead of local variable
3719 * sim_calls.c (sim_close): Ditto
3721 * device.c (device_tree_print_device): New. Prints the device
3722 tree in a format that is consistent with what can be parsed by the
3723 device tree load from file code.
3725 * psim.c (psim_create): Dump device tree if enabled. If nump
3726 selected, exit psim immediatly.
3728 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
3730 * corefile-n.h (core_map_read_N): When mapping from an address to
3731 a device, do not subtract the devices base. The device its self
3732 can do this. Brings the behavour into line with OpenBoot.
3733 * corefile-n.h (core_map_write_N): Ditto
3734 * corefile.c (core_map_read_buffer): Ditto
3735 * corefile.c (core_map_write_buffer): Ditto
3737 * device_table.c (console_io_read_buffer_callback): Adjust to
3738 handle biased address.
3739 * device_table.c (console_io_write_buffer_callback): Ditto
3741 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
3743 * device.c (attach_device_interrupt_edge): New. Interrupt model
3744 did not allow interrupts to be wired up as a general net (edges).
3745 Re-implement so that interrupt events can be passed to multiple
3746 controllers and interrupt controllers can further propogate
3749 * device.c (attach_device_interrupt_edge) : New, Ditto
3750 * device.c (detach_device_interrupt_edge) : New, Ditto
3751 * device.c (clean_device_interrupt_edges) : New, Ditto
3752 * device.c (device_interrupt_event) : New, Ditto
3753 * device.c (device_interrupt_attach) : New, Ditto
3754 * device.c (device_interrupt_detach) : New, Ditto
3755 * device.c (device_child_interrupt_attach) : New, Ditto
3756 * device.c (device_child_interrupt_detach) : New, Ditto
3758 * device.c (device_attach_interrupt) : Delete old
3759 * device.c (device_detach_interrupt) : Delete old
3760 * device.c (device_interrupt) : Delete old
3761 * device.c (device_interrupt_ack) : Delete old
3763 * device_table.c (unimp_*) : Update to match
3765 * device_table.c (icu_io_write_buffer_callback) : Update to use
3767 * device_table.c (icu_interrupt_event_callback) : Ditto
3769 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3771 * device.c (external_to_device) : New function that provides a
3772 standard mapping between a devices internal representation (a
3773 pointer) and its external (or what is passed to a client)
3774 representation (a phandle). Implement using the cap object
3775 attached to the root node.
3777 * device.c (device_to_external) : Ditto
3778 * device.c (external_to_device_instance) : Ditto but for ihandle
3779 and device instance.
3780 * device.c (device_instance_to_external) : Ditto
3782 * Makefile (device.o): Add dependency on cap.
3784 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3785 needing to translate between internal and external representations
3786 changed to use the external_to_device et.al. device operations.
3787 * emul_chirp.c (chirp_emul_*) : Ditto
3789 * Makefile (emul_chirp.o): Remove dependency on cap
3791 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3793 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3794 on OpenBoot note section.
3796 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3798 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3799 read/write calls for buffer transfers. This will cause a fault to
3800 occure if the transfer fails. CHRP catches the fault while the
3801 others suffer the consequences.
3802 (emul_read_buffer): Ditto.
3803 (emul_write_word): Ditto.
3804 (emul_read_word): Ditto.
3805 (emul_read_string): Ditto.
3807 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3809 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3810 emul_generic (emul_blr_instruction): Use a real blr instruction to
3811 return from a client service call.
3813 * emul_chirp.c (services): Add all OpenBoot services to table.
3815 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3816 (emul_chirp_create) : Use names instead of numbers for
3817 instructions being stored in memory.
3819 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3821 * Makefile.in (maintainer-clean): Remove .log, core and *.core
3822 (From NetBSD) files.
