636 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
638 * sim-endian.h: Don't have parameters on macro definitions which
639 are simply renaming functions, to permit use of XCONCAT2 in both
640 the macro name and the arguments in a use of such a definition.
642 2000-11-15 Jim Blandy <jimb@redhat.com>
644 * sim_calls.c: Doc fix.
645 (sim_fetch_register, sim_store_register): Call

680 1999-05-08 Felix Lee <flee@cygnus.com>
682 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
683 * configure: Regenerated to track ../common/aclocal.m4 changes.
685 1999-04-02 Keith Seitz <keiths@cygnus.com>

703 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
705 Make the simulator compatible with the MPC750. It would be nicer
706 to make this a real multi-sim, but that's more work than we have
708 * emul_generic.c (emul_add_tree_options): Only require strict
709 alignment if it was explicitly requested at configuration time.
710 Don't make it the default for little-endian machines.
711 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
712 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
713 THRM2, THRM3): Plop in the MPC750 SPR registers.
714 (DABR): This is weird. This was HID5, but the PPC spec says this
715 should be DABR; why did some random processor use it for something
716 else? The HID5 entry dates back to the original checkin of the
717 simulator code in 1995, so remove it.
718 * sim_calls.c (register_names): Delete this; since the user can
719 now change GDB's list of register names dynamically, we can't
720 pretend there's a static mapping here.
721 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
722 function to get the register name. That ought to be accurate.
723 However, we're changing a compile-time dependency (using the
724 REGISTER_NAMES macro) into a link- and run-time dependency
725 (calling REGISTER_NAME, which happens to be a function call on the
728 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

780 return zero when nothing to do.
782 1998-06-26 Michael Meissner <meissner@cygnus.com>
784 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
785 * configure: Regenerate.
786 * emul_{netbsd,unix}.c (toplevel): No longer try to include
787 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
789 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
791 * Makefile.in: The run target depended on a target psim$(EXEEXT),
792 but there was no such target, only plain psim. So I changed the
793 run target to depend on psim.
795 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
797 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
798 now defined in ../common/aclocal.m4, and the double definition causes
799 problems with AC_SUBST of EXEEXT.

1137 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1138 works for normal and boolean table entries.
1140 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now

1201 determine the simulation speed by looking at the number of elapsed
1202 ticks recorded by the event queue.
1204 * psim.c (psim_write_register, psim_read_register): Force the cpu
1205 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1206 next cpu would be zero any way.
1208 * mon.c (mon_print_info): If possible, print the system cycle
1209 performance. This is an indication of the number of instructions
1212 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1214 * The code to allow an event queue to be updated during a signal
1215 was missing. For main.c, a cntrl-c simulation termination wasn't
1218 * The simulation would not correctly restart if an event requested
1219 that the simulation be halted.
1221 * psim.c (psim_options): Add hack to -i option to optionally
1222 include a level vis -i2.
1223 (psim_usage): Document.

1242 * gen-idecode.c (print_run_until_stop_body): Call
1243 event_queue_process_events to clear possibly pending events before
1244 starting a simulation run. Re-arange main loop so that simulator
1245 is correctly restarted when an event halts the simulation.

1248 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1251 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1271 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1272 to be initialized independant of the rest of the simulation
1273 initalization. Otherwize a trace option explictly set from gdb
1274 could be overridden by hw_trace.
1276 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1278 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1279 debug.c. It could be much simpler.
1281 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1297 string array - use the first entry for the initial file image.
1299 * tree.c (print_string_aray_property): New function - print a

1321 the form <name>_is_<const> where it is a boolean field, generate
1322 the result of the expression instead of the expression its self.

1324 then generating corresponding definitions.
1326 * gen-icache.c (print_icache_struct): If there is no cache, do not
1327 output expressions in idecode.h file.
1329 * gen-icache.c (print_icache_body): Output them here.
1331 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1336 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1338 * The code that put values in and extracted values from the cache
1339 was too compilicated. The cache table did not allow values to be
1340 computed from cache entries. #defines could only be used when a
1341 cache was present, remove the restriction.
1343 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1344 scratch variable is defined when a cache entry is beinf
1345 filled. Change the definition of a COMPUTE variable to be defined
1346 when the cache entry is being used.
1347 * gen-icache.c: Update.
1349 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1362 * igen.c (main): Change 'R' option so that it does not force the
1365 * configure.in (enable-sim-icache): Clarify description. Make
1366 #define one of the defaults regardless of the cache. Probably
1367 should revamp and add a separate option.
1369 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1371 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
