677 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
679 * sim-endian.h: Don't have parameters on macro definitions which
680 are simply renaming functions, to permit use of XCONCAT2 in both
681 the macro name and the arguments in a use of such a definition.
683 2000-11-15 Jim Blandy <jimb@redhat.com>
685 * sim_calls.c: Doc fix.
686 (sim_fetch_register, sim_store_register): Call

721 1999-05-08 Felix Lee <flee@cygnus.com>
723 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
724 * configure: Regenerated to track ../common/aclocal.m4 changes.
726 1999-04-02 Keith Seitz <keiths@cygnus.com>

744 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
746 Make the simulator compatible with the MPC750. It would be nicer
747 to make this a real multi-sim, but that's more work than we have
749 * emul_generic.c (emul_add_tree_options): Only require strict
750 alignment if it was explicitly requested at configuration time.
751 Don't make it the default for little-endian machines.
752 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
753 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
754 THRM2, THRM3): Plop in the MPC750 SPR registers.
755 (DABR): This is weird. This was HID5, but the PPC spec says this
756 should be DABR; why did some random processor use it for something
757 else? The HID5 entry dates back to the original checkin of the
758 simulator code in 1995, so remove it.
759 * sim_calls.c (register_names): Delete this; since the user can
760 now change GDB's list of register names dynamically, we can't
761 pretend there's a static mapping here.
762 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
763 function to get the register name. That ought to be accurate.
764 However, we're changing a compile-time dependency (using the
765 REGISTER_NAMES macro) into a link- and run-time dependency
766 (calling REGISTER_NAME, which happens to be a function call on the
769 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

826 * configure: Regenerate.
827 * emul_{netbsd,unix}.c (toplevel): No longer try to include
828 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
830 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
832 * Makefile.in: The run target depended on a target psim$(EXEEXT),
833 but there was no such target, only plain psim. So I changed the
834 run target to depend on psim.
836 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
838 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
839 now defined in ../common/aclocal.m4, and the double definition causes
840 problems with AC_SUBST of EXEEXT.

1242 determine the simulation speed by looking at the number of elapsed
1243 ticks recorded by the event queue.
1245 * psim.c (psim_write_register, psim_read_register): Force the cpu
1246 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1247 next cpu would be zero any way.
1249 * mon.c (mon_print_info): If possible, print the system cycle
1250 performance. This is an indication of the number of instructions
1253 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1255 * The code to allow an event queue to be updated during a signal
1256 was missing. For main.c, a cntrl-c simulation termination wasn't
1259 * The simulation would not correctly restart if an event requested
1260 that the simulation be halted.
1262 * psim.c (psim_options): Add hack to -i option to optionally
1263 include a level vis -i2.
1264 (psim_usage): Document.

1283 * gen-idecode.c (print_run_until_stop_body): Call
1284 event_queue_process_events to clear possibly pending events before
1285 starting a simulation run. Re-arange main loop so that simulator
1286 is correctly restarted when an event halts the simulation.
1288 * psim.c (psim_halt): Handle an event halting the simulation.
1289 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1292 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1312 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1313 to be initialized independant of the rest of the simulation
1314 initalization. Otherwize a trace option explictly set from gdb
1315 could be overridden by hw_trace.
1317 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1319 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1320 debug.c. It could be much simpler.
1322 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1338 string array - use the first entry for the initial file image.
1340 * tree.c (print_string_aray_property): New function - print a

1362 the form <name>_is_<const> where it is a boolean field, generate
1363 the result of the expression instead of the expression its self.

1365 then generating corresponding definitions.
1367 * gen-icache.c (print_icache_struct): If there is no cache, do not
1368 output expressions in idecode.h file.
1370 * gen-icache.c (print_icache_body): Output them here.
1372 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1379 * The code that put values in and extracted values from the cache
1380 was too compilicated. The cache table did not allow values to be
1381 computed from cache entries. #defines could only be used when a
1382 cache was present, remove the restriction.
1384 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1385 scratch variable is defined when a cache entry is beinf
1386 filled. Change the definition of a COMPUTE variable to be defined
1387 when the cache entry is being used.
1388 * gen-icache.c: Update.
1390 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1399 * gen-semantics.c (print_c_semantic): Update use.
1400 * gen-idecode.c (print_jump_insn): Update use.
1401 * gen-icache.c (print_icache_function): Update use.
1403 * igen.c (main): Change 'R' option so that it does not force the
1406 * configure.in (enable-sim-icache): Clarify description. Make
1407 #define one of the defaults regardless of the cache. Probably
1408 should revamp and add a separate option.
1410 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1412 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
