639 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
641 * sim-endian.h: Don't have parameters on macro definitions which
642 are simply renaming functions, to permit use of XCONCAT2 in both
643 the macro name and the arguments in a use of such a definition.
645 2000-11-15 Jim Blandy <jimb@redhat.com>
647 * sim_calls.c: Doc fix.
648 (sim_fetch_register, sim_store_register): Call

683 1999-05-08 Felix Lee <flee@cygnus.com>
685 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
686 * configure: Regenerated to track ../common/aclocal.m4 changes.
688 1999-04-02 Keith Seitz <keiths@cygnus.com>

706 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
708 Make the simulator compatible with the MPC750. It would be nicer
709 to make this a real multi-sim, but that's more work than we have
711 * emul_generic.c (emul_add_tree_options): Only require strict
712 alignment if it was explicitly requested at configuration time.
713 Don't make it the default for little-endian machines.
714 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
715 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
716 THRM2, THRM3): Plop in the MPC750 SPR registers.
717 (DABR): This is weird. This was HID5, but the PPC spec says this
718 should be DABR; why did some random processor use it for something
719 else? The HID5 entry dates back to the original checkin of the
720 simulator code in 1995, so remove it.
721 * sim_calls.c (register_names): Delete this; since the user can
722 now change GDB's list of register names dynamically, we can't
723 pretend there's a static mapping here.
724 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
725 function to get the register name. That ought to be accurate.
726 However, we're changing a compile-time dependency (using the
727 REGISTER_NAMES macro) into a link- and run-time dependency
728 (calling REGISTER_NAME, which happens to be a function call on the
731 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

783 return zero when nothing to do.
785 1998-06-26 Michael Meissner <meissner@cygnus.com>

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

895 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
897 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,

1141 works for normal and boolean table entries.
1143 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now

1204 determine the simulation speed by looking at the number of elapsed
1205 ticks recorded by the event queue.
1207 * psim.c (psim_write_register, psim_read_register): Force the cpu
1208 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1209 next cpu would be zero any way.
1211 * mon.c (mon_print_info): If possible, print the system cycle
1212 performance. This is an indication of the number of instructions
1215 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1217 * The code to allow an event queue to be updated during a signal
1218 was missing. For main.c, a cntrl-c simulation termination wasn't
1221 * The simulation would not correctly restart if an event requested
1222 that the simulation be halted.
1224 * psim.c (psim_options): Add hack to -i option to optionally
1225 include a level vis -i2.
1226 (psim_usage): Document.

1245 * gen-idecode.c (print_run_until_stop_body): Call
1246 event_queue_process_events to clear possibly pending events before
1247 starting a simulation run. Re-arange main loop so that simulator
1248 is correctly restarted when an event halts the simulation.

1274 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1275 to be initialized independant of the rest of the simulation
1276 initalization. Otherwize a trace option explictly set from gdb
1277 could be overridden by hw_trace.
1279 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1281 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1282 debug.c. It could be much simpler.
1284 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1324 the form <name>_is_<const> where it is a boolean field, generate
1325 the result of the expression instead of the expression its self.

1327 then generating corresponding definitions.
1329 * gen-icache.c (print_icache_struct): If there is no cache, do not
1330 output expressions in idecode.h file.
1332 * gen-icache.c (print_icache_body): Output them here.
1334 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1341 * The code that put values in and extracted values from the cache
1342 was too compilicated. The cache table did not allow values to be
1343 computed from cache entries. #defines could only be used when a
1344 cache was present, remove the restriction.
1346 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1347 scratch variable is defined when a cache entry is beinf
1348 filled. Change the definition of a COMPUTE variable to be defined
1349 when the cache entry is being used.
1350 * gen-icache.c: Update.
1352 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1365 * igen.c (main): Change 'R' option so that it does not force the
1368 * configure.in (enable-sim-icache): Clarify description. Make
1369 #define one of the defaults regardless of the cache. Probably
1370 should revamp and add a separate option.
