204 are simply renaming functions, to permit use of XCONCAT2 in both
205 the macro name and the arguments in a use of such a definition.
207 2000-11-15 Jim Blandy <jimb@redhat.com>
209 * sim_calls.c: Doc fix.
210 (sim_fetch_register, sim_store_register): Call

245 1999-05-08 Felix Lee <flee@cygnus.com>
247 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.

250 1999-04-02 Keith Seitz <keiths@cygnus.com>

268 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
270 Make the simulator compatible with the MPC750. It would be nicer
271 to make this a real multi-sim, but that's more work than we have
273 * emul_generic.c (emul_add_tree_options): Only require strict
274 alignment if it was explicitly requested at configuration time.
275 Don't make it the default for little-endian machines.
276 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
277 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
278 THRM2, THRM3): Plop in the MPC750 SPR registers.
279 (DABR): This is weird. This was HID5, but the PPC spec says this
280 should be DABR; why did some random processor use it for something
281 else? The HID5 entry dates back to the original checkin of the
282 simulator code in 1995, so remove it.
283 * sim_calls.c (register_names): Delete this; since the user can
284 now change GDB's list of register names dynamically, we can't
285 pretend there's a static mapping here.
286 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
287 function to get the register name. That ought to be accurate.
288 However, we're changing a compile-time dependency (using the
289 REGISTER_NAMES macro) into a link- and run-time dependency
290 (calling REGISTER_NAME, which happens to be a function call on the
293 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

344 * sim_calls.c (sim_fetch_register, sim_store_register):
345 return zero when nothing to do.
347 1998-06-26 Michael Meissner <meissner@cygnus.com>
349 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
350 * configure: Regenerate.
351 * emul_{netbsd,unix}.c (toplevel): No longer try to include
352 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
354 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
356 * Makefile.in: The run target depended on a target psim$(EXEEXT),
357 but there was no such target, only plain psim. So I changed the
358 run target to depend on psim.
360 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
362 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
363 now defined in ../common/aclocal.m4, and the double definition causes
364 problems with AC_SUBST of EXEEXT.

766 determine the simulation speed by looking at the number of elapsed
767 ticks recorded by the event queue.
769 * psim.c (psim_write_register, psim_read_register): Force the cpu
770 to zero when it is either of `-1' or `nr_cpus'. In both cases the
771 next cpu would be zero any way.
773 * mon.c (mon_print_info): If possible, print the system cycle
774 performance. This is an indication of the number of instructions
777 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
779 * The code to allow an event queue to be updated during a signal
780 was missing. For main.c, a cntrl-c simulation termination wasn't
783 * The simulation would not correctly restart if an event requested
784 that the simulation be halted.

802 (event_queue_init): Start the event queue out with processing
804 (event_queue_tick): Check that processing isn't still being
807 * gen-idecode.c (print_run_until_stop_body): Call

836 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
837 to be initialized independant of the rest of the simulation

839 could be overridden by hw_trace.
841 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
843 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
844 debug.c. It could be much simpler.
846 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
848 * Some devices support removable media. Add hooks to the disk

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

903 * The code that put values in and extracted values from the cache
904 was too compilicated. The cache table did not allow values to be
905 computed from cache entries. #defines could only be used when a
906 cache was present, remove the restriction.
908 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
909 scratch variable is defined when a cache entry is beinf
910 filled. Change the definition of a COMPUTE variable to be defined
911 when the cache entry is being used.
912 * gen-icache.c: Update.
914 * ld-cache.h, ld-cache.c: Change field names so that their meaning
915 is more obvious. old_name->field_name, new_name->derived_name.
916 * gen-icache.c: Update
918 * gen-icache.h, gen-icache.c (print_icache_body): Make the three

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