628 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
630 * sim-endian.h: Don't have parameters on macro definitions which
631 are simply renaming functions, to permit use of XCONCAT2 in both
632 the macro name and the arguments in a use of such a definition.
634 2000-11-15 Jim Blandy <jimb@redhat.com>
636 * sim_calls.c: Doc fix.
637 (sim_fetch_register, sim_store_register): Call

672 1999-05-08 Felix Lee <flee@cygnus.com>
674 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
675 * configure: Regenerated to track ../common/aclocal.m4 changes.
677 1999-04-02 Keith Seitz <keiths@cygnus.com>

695 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
697 Make the simulator compatible with the MPC750. It would be nicer
698 to make this a real multi-sim, but that's more work than we have
700 * emul_generic.c (emul_add_tree_options): Only require strict
701 alignment if it was explicitly requested at configuration time.
702 Don't make it the default for little-endian machines.
703 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
704 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
705 THRM2, THRM3): Plop in the MPC750 SPR registers.
706 (DABR): This is weird. This was HID5, but the PPC spec says this
707 should be DABR; why did some random processor use it for something
708 else? The HID5 entry dates back to the original checkin of the
709 simulator code in 1995, so remove it.
710 * sim_calls.c (register_names): Delete this; since the user can
711 now change GDB's list of register names dynamically, we can't
712 pretend there's a static mapping here.
713 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
714 function to get the register name. That ought to be accurate.
715 However, we're changing a compile-time dependency (using the
716 REGISTER_NAMES macro) into a link- and run-time dependency
717 (calling REGISTER_NAME, which happens to be a function call on the
720 1999-01-22 Jim Lemke <jlemke@cygnus.com>

746 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
747 fractional type, so that quiet NaN's aren't treated like
750 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
752 * table.c (table_open): For cygwin hosts, we need to use the
753 return value from the read routine as the number of bytes to
754 process. This apparently is due to text-mode vs binary-mode. If
755 the mounts are done text-mode, then the size returnedby fstat()
756 may be different than the number of bytes "read" in text mode.
758 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
760 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

772 return zero when nothing to do.
774 1998-06-26 Michael Meissner <meissner@cygnus.com>

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

884 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
886 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,
888 * words.h: __int64 instead of long long for MSVC.

1193 determine the simulation speed by looking at the number of elapsed
1194 ticks recorded by the event queue.
1196 * psim.c (psim_write_register, psim_read_register): Force the cpu
1197 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1198 next cpu would be zero any way.
1200 * mon.c (mon_print_info): If possible, print the system cycle
1201 performance. This is an indication of the number of instructions
1204 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1206 * The code to allow an event queue to be updated during a signal
1207 was missing. For main.c, a cntrl-c simulation termination wasn't
1210 * The simulation would not correctly restart if an event requested
1211 that the simulation be halted.
1213 * psim.c (psim_options): Add hack to -i option to optionally
1214 include a level vis -i2.
1215 (psim_usage): Document.

1234 * gen-idecode.c (print_run_until_stop_body): Call
1235 event_queue_process_events to clear possibly pending events before

1263 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1264 to be initialized independant of the rest of the simulation
1265 initalization. Otherwize a trace option explictly set from gdb
1266 could be overridden by hw_trace.
1268 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1270 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1271 debug.c. It could be much simpler.
1273 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1313 the form <name>_is_<const> where it is a boolean field, generate
1314 the result of the expression instead of the expression its self.

1319 output expressions in idecode.h file.
1321 * gen-icache.c (print_icache_body): Output them here.

1330 * The code that put values in and extracted values from the cache
1331 was too compilicated. The cache table did not allow values to be
1332 computed from cache entries. #defines could only be used when a
1333 cache was present, remove the restriction.
1335 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1336 scratch variable is defined when a cache entry is beinf
1337 filled. Change the definition of a COMPUTE variable to be defined
1338 when the cache entry is being used.
1339 * gen-icache.c: Update.
1341 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1354 * igen.c (main): Change 'R' option so that it does not force the
1357 * configure.in (enable-sim-icache): Clarify description. Make
1358 #define one of the defaults regardless of the cache. Probably
1359 should revamp and add a separate option.

3724 * psim.c(psim_options): Parse the psim options, installing their
3725 value in the device tree. Options are now first entered into a
3726 device tree and then extracted out again when needed. This allows
3727 greater flexability in configuration.

3752 things. Extract all information from the device tree.
3754 * device_tree.c (trace_*): New device node, its properties are
3755 used to set the value of the trace options. Init this device (in
3756 psim_options) when ever the options are updated.

3760 * debug.h: Add trace_print_info, trace_print_device_tree and
3761 trace_dump_device_tree. The first is a replacement for the
3762 variable `print_info' found in main.c and sim_calls.c. The latter
3763 two enable the dumping of the entire device tree.
3765 * debug.c: Add to trace_description table.
3767 * main.c (main): Use above trace instead of local variable
3768 * sim_calls.c (sim_close): Ditto

3779 * corefile-n.h (core_map_read_N): When mapping from an address to
3780 a device, do not subtract the devices base. The device its self
3781 can do this. Brings the behavour into line with OpenBoot.
3782 * corefile-n.h (core_map_write_N): Ditto
3783 * corefile.c (core_map_read_buffer): Ditto
3784 * corefile.c (core_map_write_buffer): Ditto
3786 * device_table.c (console_io_read_buffer_callback): Adjust to
3787 handle biased address.
3788 * device_table.c (console_io_write_buffer_callback): Ditto
3790 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
3792 * device.c (attach_device_interrupt_edge): New. Interrupt model
3793 did not allow interrupts to be wired up as a general net (edges).
3794 Re-implement so that interrupt events can be passed to multiple
3795 controllers and interrupt controllers can further propogate

3820 * device.c (external_to_device) : New function that provides a
3821 standard mapping between a devices internal representation (a
3822 pointer) and its external (or what is passed to a client)
3823 representation (a phandle). Implement using the cap object
3824 attached to the root node.
3826 * device.c (device_to_external) : Ditto
3827 * device.c (external_to_device_instance) : Ditto but for ihandle
3828 and device instance.

3847 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3848 read/write calls for buffer transfers. This will cause a fault to
3849 occure if the transfer fails. CHRP catches the fault while the
3850 others suffer the consequences.
