743 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
745 * sim-endian.h: Don't have parameters on macro definitions which
746 are simply renaming functions, to permit use of XCONCAT2 in both
747 the macro name and the arguments in a use of such a definition.
749 2000-11-15 Jim Blandy <jimb@redhat.com>
751 * sim_calls.c: Doc fix.
752 (sim_fetch_register, sim_store_register): Call

787 1999-05-08 Felix Lee <flee@cygnus.com>
789 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
790 * configure: Regenerated to track ../common/aclocal.m4 changes.
792 1999-04-02 Keith Seitz <keiths@cygnus.com>

798 after the specified POLL_QUIT_INTERVAL.
800 1999-02-22 Jim Lemke <jlemke@cygnus.com>
802 * dc-complex: Force expansion on all bits of field BO.

810 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
812 Make the simulator compatible with the MPC750. It would be nicer
813 to make this a real multi-sim, but that's more work than we have
815 * emul_generic.c (emul_add_tree_options): Only require strict
816 alignment if it was explicitly requested at configuration time.
817 Don't make it the default for little-endian machines.
818 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
819 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
820 THRM2, THRM3): Plop in the MPC750 SPR registers.
821 (DABR): This is weird. This was HID5, but the PPC spec says this
822 should be DABR; why did some random processor use it for something
823 else? The HID5 entry dates back to the original checkin of the
824 simulator code in 1995, so remove it.
825 * sim_calls.c (register_names): Delete this; since the user can
826 now change GDB's list of register names dynamically, we can't
827 pretend there's a static mapping here.
828 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
829 function to get the register name. That ought to be accurate.
830 However, we're changing a compile-time dependency (using the
831 REGISTER_NAMES macro) into a link- and run-time dependency
832 (calling REGISTER_NAME, which happens to be a function call on the
835 1999-01-22 Jim Lemke <jlemke@cygnus.com>

842 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
844 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
846 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

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

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

997 (ldhau): From Johannes Reisinger, update rA after load.
999 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
1001 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,
1003 * words.h: __int64 instead of long long for MSVC.
1005 Wed Aug 27 10:24:15 1997 Andrew Cagney <cagney@b1.cygnus.com>

1015 * sim_calls.c (sim_load): From Ian Lance Taylor - free argv after

1036 - sense of wrap test in check for overwriting RA wrong.
1037 (Load String Word Indexed): Ditto.

1308 determine the simulation speed by looking at the number of elapsed
1309 ticks recorded by the event queue.
1311 * psim.c (psim_write_register, psim_read_register): Force the cpu
1312 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1313 next cpu would be zero any way.
1315 * mon.c (mon_print_info): If possible, print the system cycle
1316 performance. This is an indication of the number of instructions
1319 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1321 * The code to allow an event queue to be updated during a signal
1322 was missing. For main.c, a cntrl-c simulation termination wasn't
1325 * The simulation would not correctly restart if an event requested
1326 that the simulation be halted.
1328 * psim.c (psim_options): Add hack to -i option to optionally
1329 include a level vis -i2.
1330 (psim_usage): Document.

1349 * gen-idecode.c (print_run_until_stop_body): Call
1350 event_queue_process_events to clear possibly pending events before
1351 starting a simulation run. Re-arange main loop so that simulator
1352 is correctly restarted when an event halts the simulation.

1378 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1379 to be initialized independant of the rest of the simulation
1380 initalization. Otherwize a trace option explictly set from gdb
1381 could be overridden by hw_trace.
1383 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1385 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1386 debug.c. It could be much simpler.
1388 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1428 the form <name>_is_<const> where it is a boolean field, generate
1429 the result of the expression instead of the expression its self.

1445 * The code that put values in and extracted values from the cache
1446 was too compilicated. The cache table did not allow values to be
1447 computed from cache entries. #defines could only be used when a
1448 cache was present, remove the restriction.
1450 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1451 scratch variable is defined when a cache entry is beinf
1452 filled. Change the definition of a COMPUTE variable to be defined
1453 when the cache entry is being used.
1454 * gen-icache.c: Update.
1456 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1465 * gen-semantics.c (print_c_semantic): Update use.
1466 * gen-idecode.c (print_jump_insn): Update use.
1467 * gen-icache.c (print_icache_function): Update use.
1469 * igen.c (main): Change 'R' option so that it does not force the
1472 * configure.in (enable-sim-icache): Clarify description. Make
1473 #define one of the defaults regardless of the cache. Probably
1474 should revamp and add a separate option.
1476 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1478 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1489 device after it was deleted. Instead add and remove cap's from the
1490 cap db as they are created and deleted. This ensuring that a
1491 capibility is only used during the lifetime of the corresponding
