739 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
741 * sim-endian.h: Don't have parameters on macro definitions which
742 are simply renaming functions, to permit use of XCONCAT2 in both
743 the macro name and the arguments in a use of such a definition.
745 2000-11-15 Jim Blandy <jimb@redhat.com>
747 * sim_calls.c: Doc fix.
748 (sim_fetch_register, sim_store_register): Call

783 1999-05-08 Felix Lee <flee@cygnus.com>
785 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
786 * configure: Regenerated to track ../common/aclocal.m4 changes.
788 1999-04-02 Keith Seitz <keiths@cygnus.com>

806 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
808 Make the simulator compatible with the MPC750. It would be nicer
809 to make this a real multi-sim, but that's more work than we have
811 * emul_generic.c (emul_add_tree_options): Only require strict
812 alignment if it was explicitly requested at configuration time.
813 Don't make it the default for little-endian machines.
814 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
815 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
816 THRM2, THRM3): Plop in the MPC750 SPR registers.
817 (DABR): This is weird. This was HID5, but the PPC spec says this
818 should be DABR; why did some random processor use it for something
819 else? The HID5 entry dates back to the original checkin of the
820 simulator code in 1995, so remove it.
821 * sim_calls.c (register_names): Delete this; since the user can
822 now change GDB's list of register names dynamically, we can't
823 pretend there's a static mapping here.
824 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
825 function to get the register name. That ought to be accurate.
826 However, we're changing a compile-time dependency (using the
827 REGISTER_NAMES macro) into a link- and run-time dependency
828 (calling REGISTER_NAME, which happens to be a function call on the
831 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

882 * sim_calls.c (sim_fetch_register, sim_store_register):
883 return zero when nothing to do.
885 1998-06-26 Michael Meissner <meissner@cygnus.com>
887 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
888 * configure: Regenerate.
889 * emul_{netbsd,unix}.c (toplevel): No longer try to include
890 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
892 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
894 * Makefile.in: The run target depended on a target psim$(EXEEXT),
895 but there was no such target, only plain psim. So I changed the
896 run target to depend on psim.
898 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
900 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
901 now defined in ../common/aclocal.m4, and the double definition causes
902 problems with AC_SUBST of EXEEXT.

993 (ldhau): From Johannes Reisinger, update rA after load.
995 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
997 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,
999 * words.h: __int64 instead of long long for MSVC.
1001 Wed Aug 27 10:24:15 1997 Andrew Cagney <cagney@b1.cygnus.com>

1032 - sense of wrap test in check for overwriting RA wrong.
1033 (Load String Word Indexed): Ditto.

1304 determine the simulation speed by looking at the number of elapsed
1305 ticks recorded by the event queue.
1307 * psim.c (psim_write_register, psim_read_register): Force the cpu
1308 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1309 next cpu would be zero any way.
1311 * mon.c (mon_print_info): If possible, print the system cycle
1312 performance. This is an indication of the number of instructions
1315 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1317 * The code to allow an event queue to be updated during a signal
1318 was missing. For main.c, a cntrl-c simulation termination wasn't
1321 * The simulation would not correctly restart if an event requested
1322 that the simulation be halted.
1324 * psim.c (psim_options): Add hack to -i option to optionally
1325 include a level vis -i2.
1326 (psim_usage): Document.

1345 * gen-idecode.c (print_run_until_stop_body): Call
1346 event_queue_process_events to clear possibly pending events before

1374 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1375 to be initialized independant of the rest of the simulation
1376 initalization. Otherwize a trace option explictly set from gdb
1377 could be overridden by hw_trace.
1379 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1381 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1382 debug.c. It could be much simpler.

1424 the form <name>_is_<const> where it is a boolean field, generate
1425 the result of the expression instead of the expression its self.

1441 * The code that put values in and extracted values from the cache
1442 was too compilicated. The cache table did not allow values to be
1443 computed from cache entries. #defines could only be used when a
1444 cache was present, remove the restriction.
1446 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1447 scratch variable is defined when a cache entry is beinf
1448 filled. Change the definition of a COMPUTE variable to be defined
1449 when the cache entry is being used.
1450 * gen-icache.c: Update.
1452 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1461 * gen-semantics.c (print_c_semantic): Update use.
1462 * gen-idecode.c (print_jump_insn): Update use.
1463 * gen-icache.c (print_icache_function): Update use.
1465 * igen.c (main): Change 'R' option so that it does not force the
1468 * configure.in (enable-sim-icache): Clarify description. Make
1469 #define one of the defaults regardless of the cache. Probably
1470 should revamp and add a separate option.
1472 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1474 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
