733 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
735 * sim-endian.h: Don't have parameters on macro definitions which
736 are simply renaming functions, to permit use of XCONCAT2 in both
737 the macro name and the arguments in a use of such a definition.
739 2000-11-15 Jim Blandy <jimb@redhat.com>
741 * sim_calls.c: Doc fix.
742 (sim_fetch_register, sim_store_register): Call

777 1999-05-08 Felix Lee <flee@cygnus.com>
779 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
780 * configure: Regenerated to track ../common/aclocal.m4 changes.
782 1999-04-02 Keith Seitz <keiths@cygnus.com>

800 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
802 Make the simulator compatible with the MPC750. It would be nicer
803 to make this a real multi-sim, but that's more work than we have
805 * emul_generic.c (emul_add_tree_options): Only require strict
806 alignment if it was explicitly requested at configuration time.
807 Don't make it the default for little-endian machines.
808 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
809 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
810 THRM2, THRM3): Plop in the MPC750 SPR registers.
811 (DABR): This is weird. This was HID5, but the PPC spec says this
812 should be DABR; why did some random processor use it for something
813 else? The HID5 entry dates back to the original checkin of the
814 simulator code in 1995, so remove it.
815 * sim_calls.c (register_names): Delete this; since the user can
816 now change GDB's list of register names dynamically, we can't
817 pretend there's a static mapping here.
818 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
819 function to get the register name. That ought to be accurate.
820 However, we're changing a compile-time dependency (using the
821 REGISTER_NAMES macro) into a link- and run-time dependency
822 (calling REGISTER_NAME, which happens to be a function call on the
825 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

876 * sim_calls.c (sim_fetch_register, sim_store_register):
877 return zero when nothing to do.
879 1998-06-26 Michael Meissner <meissner@cygnus.com>
881 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
882 * configure: Regenerate.
883 * emul_{netbsd,unix}.c (toplevel): No longer try to include
884 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
886 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
888 * Makefile.in: The run target depended on a target psim$(EXEEXT),
889 but there was no such target, only plain psim. So I changed the
890 run target to depend on psim.
892 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
894 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
895 now defined in ../common/aclocal.m4, and the double definition causes
896 problems with AC_SUBST of EXEEXT.

987 (ldhau): From Johannes Reisinger, update rA after load.
989 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
991 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,
993 * words.h: __int64 instead of long long for MSVC.

1026 - sense of wrap test in check for overwriting RA wrong.
1027 (Load String Word Indexed): Ditto.

1298 determine the simulation speed by looking at the number of elapsed
1299 ticks recorded by the event queue.
1301 * psim.c (psim_write_register, psim_read_register): Force the cpu
1302 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1303 next cpu would be zero any way.
1305 * mon.c (mon_print_info): If possible, print the system cycle
1306 performance. This is an indication of the number of instructions
1309 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1311 * The code to allow an event queue to be updated during a signal
1312 was missing. For main.c, a cntrl-c simulation termination wasn't
1315 * The simulation would not correctly restart if an event requested
1316 that the simulation be halted.
1318 * psim.c (psim_options): Add hack to -i option to optionally
1319 include a level vis -i2.
1320 (psim_usage): Document.

1339 * gen-idecode.c (print_run_until_stop_body): Call
1340 event_queue_process_events to clear possibly pending events before
1341 starting a simulation run. Re-arange main loop so that simulator
1342 is correctly restarted when an event halts the simulation.

1368 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1369 to be initialized independant of the rest of the simulation
1370 initalization. Otherwize a trace option explictly set from gdb
1371 could be overridden by hw_trace.
1373 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1375 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1376 debug.c. It could be much simpler.
1378 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1394 string array - use the first entry for the initial file image.
1396 * tree.c (print_string_aray_property): New function - print a

1418 the form <name>_is_<const> where it is a boolean field, generate
1419 the result of the expression instead of the expression its self.

1424 output expressions in idecode.h file.
1426 * gen-icache.c (print_icache_body): Output them here.
1428 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1435 * The code that put values in and extracted values from the cache
1436 was too compilicated. The cache table did not allow values to be
1437 computed from cache entries. #defines could only be used when a
1438 cache was present, remove the restriction.
1440 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1441 scratch variable is defined when a cache entry is beinf
1442 filled. Change the definition of a COMPUTE variable to be defined
1443 when the cache entry is being used.
1444 * gen-icache.c: Update.
1446 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1455 * gen-semantics.c (print_c_semantic): Update use.
1456 * gen-idecode.c (print_jump_insn): Update use.
1457 * gen-icache.c (print_icache_function): Update use.
1459 * igen.c (main): Change 'R' option so that it does not force the
1462 * configure.in (enable-sim-icache): Clarify description. Make
1463 #define one of the defaults regardless of the cache. Probably
1464 should revamp and add a separate option.
1466 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1468 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1479 device after it was deleted. Instead add and remove cap's from the
1480 cap db as they are created and deleted. This ensuring that a
1481 capibility is only used during the lifetime of the corresponding
