647 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
649 * sim-endian.h: Don't have parameters on macro definitions which
650 are simply renaming functions, to permit use of XCONCAT2 in both
651 the macro name and the arguments in a use of such a definition.
653 2000-11-15 Jim Blandy <jimb@redhat.com>
655 * sim_calls.c: Doc fix.
656 (sim_fetch_register, sim_store_register): Call

691 1999-05-08 Felix Lee <flee@cygnus.com>
693 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
694 * configure: Regenerated to track ../common/aclocal.m4 changes.
696 1999-04-02 Keith Seitz <keiths@cygnus.com>

702 after the specified POLL_QUIT_INTERVAL.
704 1999-02-22 Jim Lemke <jlemke@cygnus.com>
706 * dc-complex: Force expansion on all bits of field BO.

714 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
716 Make the simulator compatible with the MPC750. It would be nicer
717 to make this a real multi-sim, but that's more work than we have
719 * emul_generic.c (emul_add_tree_options): Only require strict
720 alignment if it was explicitly requested at configuration time.
721 Don't make it the default for little-endian machines.
722 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
723 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
724 THRM2, THRM3): Plop in the MPC750 SPR registers.
725 (DABR): This is weird. This was HID5, but the PPC spec says this
726 should be DABR; why did some random processor use it for something
727 else? The HID5 entry dates back to the original checkin of the
728 simulator code in 1995, so remove it.
729 * sim_calls.c (register_names): Delete this; since the user can
730 now change GDB's list of register names dynamically, we can't
731 pretend there's a static mapping here.
732 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
733 function to get the register name. That ought to be accurate.
734 However, we're changing a compile-time dependency (using the
735 REGISTER_NAMES macro) into a link- and run-time dependency
736 (calling REGISTER_NAME, which happens to be a function call on the
739 1999-01-22 Jim Lemke <jlemke@cygnus.com>

746 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
748 1998-12-01 Ken Raeburn <raeburn@cygnus.com>

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

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

903 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
905 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,
907 * words.h: __int64 instead of long long for MSVC.

1020 * Makefile.in (tmp-hw, tmp-pk): Use for loop to eliminate duplicates

1148 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1149 works for normal and boolean table entries.
1151 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now

1209 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1211 * When performance monitoring is disabled, it is still possible to
1212 determine the simulation speed by looking at the number of elapsed
1213 ticks recorded by the event queue.
1215 * psim.c (psim_write_register, psim_read_register): Force the cpu
1216 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1217 next cpu would be zero any way.
1219 * mon.c (mon_print_info): If possible, print the system cycle
1220 performance. This is an indication of the number of instructions
1223 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1225 * The code to allow an event queue to be updated during a signal
1226 was missing. For main.c, a cntrl-c simulation termination wasn't
1229 * The simulation would not correctly restart if an event requested
1230 that the simulation be halted.
1232 * psim.c (psim_options): Add hack to -i option to optionally
1233 include a level vis -i2.
1234 (psim_usage): Document.

1253 * gen-idecode.c (print_run_until_stop_body): Call
1254 event_queue_process_events to clear possibly pending events before
1255 starting a simulation run. Re-arange main loop so that simulator
1256 is correctly restarted when an event halts the simulation.
1258 * psim.c (psim_halt): Handle an event halting the simulation.
1259 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1262 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1264 * ppc-opcode-complex: Correct typo - was expanding ORA instead of

1282 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1283 to be initialized independant of the rest of the simulation
1284 initalization. Otherwize a trace option explictly set from gdb
1285 could be overridden by hw_trace.
1287 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1289 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1290 debug.c. It could be much simpler.
1292 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1308 string array - use the first entry for the initial file image.
1310 * tree.c (print_string_aray_property): New function - print a

1332 the form <name>_is_<const> where it is a boolean field, generate
1333 the result of the expression instead of the expression its self.

1335 then generating corresponding definitions.
1337 * gen-icache.c (print_icache_struct): If there is no cache, do not
1338 output expressions in idecode.h file.
1340 * gen-icache.c (print_icache_body): Output them here.
1342 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1349 * The code that put values in and extracted values from the cache
1350 was too compilicated. The cache table did not allow values to be
1351 computed from cache entries. #defines could only be used when a
1352 cache was present, remove the restriction.
1354 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1355 scratch variable is defined when a cache entry is beinf
1356 filled. Change the definition of a COMPUTE variable to be defined
1357 when the cache entry is being used.
1358 * gen-icache.c: Update.
1360 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1373 * igen.c (main): Change 'R' option so that it does not force the
1376 * configure.in (enable-sim-icache): Clarify description. Make
1377 #define one of the defaults regardless of the cache. Probably
1378 should revamp and add a separate option.
1380 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1382 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
