729 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
731 * sim-endian.h: Don't have parameters on macro definitions which
732 are simply renaming functions, to permit use of XCONCAT2 in both
733 the macro name and the arguments in a use of such a definition.
735 2000-11-15 Jim Blandy <jimb@redhat.com>
737 * sim_calls.c: Doc fix.
738 (sim_fetch_register, sim_store_register): Call

773 1999-05-08 Felix Lee <flee@cygnus.com>
775 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
776 * configure: Regenerated to track ../common/aclocal.m4 changes.
778 1999-04-02 Keith Seitz <keiths@cygnus.com>

796 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
798 Make the simulator compatible with the MPC750. It would be nicer
799 to make this a real multi-sim, but that's more work than we have
801 * emul_generic.c (emul_add_tree_options): Only require strict
802 alignment if it was explicitly requested at configuration time.
803 Don't make it the default for little-endian machines.
804 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
805 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
806 THRM2, THRM3): Plop in the MPC750 SPR registers.
807 (DABR): This is weird. This was HID5, but the PPC spec says this
808 should be DABR; why did some random processor use it for something
809 else? The HID5 entry dates back to the original checkin of the
810 simulator code in 1995, so remove it.
811 * sim_calls.c (register_names): Delete this; since the user can
812 now change GDB's list of register names dynamically, we can't
813 pretend there's a static mapping here.
814 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
815 function to get the register name. That ought to be accurate.
816 However, we're changing a compile-time dependency (using the
817 REGISTER_NAMES macro) into a link- and run-time dependency
818 (calling REGISTER_NAME, which happens to be a function call on the
821 1999-01-22 Jim Lemke <jlemke@cygnus.com>

828 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

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

872 * sim_calls.c (sim_fetch_register, sim_store_register):
873 return zero when nothing to do.
875 1998-06-26 Michael Meissner <meissner@cygnus.com>
877 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
878 * configure: Regenerate.
879 * emul_{netbsd,unix}.c (toplevel): No longer try to include
880 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
882 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
884 * Makefile.in: The run target depended on a target psim$(EXEEXT),
885 but there was no such target, only plain psim. So I changed the
886 run target to depend on psim.
888 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
890 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
891 now defined in ../common/aclocal.m4, and the double definition causes
892 problems with AC_SUBST of EXEEXT.

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

1294 determine the simulation speed by looking at the number of elapsed
1295 ticks recorded by the event queue.
1297 * psim.c (psim_write_register, psim_read_register): Force the cpu
1298 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1299 next cpu would be zero any way.
1301 * mon.c (mon_print_info): If possible, print the system cycle
1302 performance. This is an indication of the number of instructions
1305 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1307 * The code to allow an event queue to be updated during a signal
1308 was missing. For main.c, a cntrl-c simulation termination wasn't
1311 * The simulation would not correctly restart if an event requested
1312 that the simulation be halted.
1314 * psim.c (psim_options): Add hack to -i option to optionally
1315 include a level vis -i2.
1316 (psim_usage): Document.

1335 * gen-idecode.c (print_run_until_stop_body): Call
1336 event_queue_process_events to clear possibly pending events before
1337 starting a simulation run. Re-arange main loop so that simulator
1338 is correctly restarted when an event halts the simulation.

1364 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1365 to be initialized independant of the rest of the simulation
1366 initalization. Otherwize a trace option explictly set from gdb
1367 could be overridden by hw_trace.
1369 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1371 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1372 debug.c. It could be much simpler.

1390 string array - use the first entry for the initial file image.
1392 * tree.c (print_string_aray_property): New function - print a

1414 the form <name>_is_<const> where it is a boolean field, generate
1415 the result of the expression instead of the expression its self.

1431 * The code that put values in and extracted values from the cache
1432 was too compilicated. The cache table did not allow values to be
1433 computed from cache entries. #defines could only be used when a
1434 cache was present, remove the restriction.
1436 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1437 scratch variable is defined when a cache entry is beinf
1438 filled. Change the definition of a COMPUTE variable to be defined
1439 when the cache entry is being used.
1440 * gen-icache.c: Update.
1442 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1451 * gen-semantics.c (print_c_semantic): Update use.
1452 * gen-idecode.c (print_jump_insn): Update use.
1453 * gen-icache.c (print_icache_function): Update use.
1455 * igen.c (main): Change 'R' option so that it does not force the
1458 * configure.in (enable-sim-icache): Clarify description. Make
1459 #define one of the defaults regardless of the cache. Probably
1460 should revamp and add a separate option.
1462 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1464 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
