671 are simply renaming functions, to permit use of XCONCAT2 in both
672 the macro name and the arguments in a use of such a definition.
674 2000-11-15 Jim Blandy <jimb@redhat.com>
676 * sim_calls.c: Doc fix.
677 (sim_fetch_register, sim_store_register): Call

712 1999-05-08 Felix Lee <flee@cygnus.com>
714 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
715 * configure: Regenerated to track ../common/aclocal.m4 changes.
717 1999-04-02 Keith Seitz <keiths@cygnus.com>

735 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
737 Make the simulator compatible with the MPC750. It would be nicer
738 to make this a real multi-sim, but that's more work than we have
740 * emul_generic.c (emul_add_tree_options): Only require strict
741 alignment if it was explicitly requested at configuration time.
742 Don't make it the default for little-endian machines.
743 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
744 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
745 THRM2, THRM3): Plop in the MPC750 SPR registers.
746 (DABR): This is weird. This was HID5, but the PPC spec says this
747 should be DABR; why did some random processor use it for something
748 else? The HID5 entry dates back to the original checkin of the
749 simulator code in 1995, so remove it.
750 * sim_calls.c (register_names): Delete this; since the user can
751 now change GDB's list of register names dynamically, we can't
752 pretend there's a static mapping here.
753 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
754 function to get the register name. That ought to be accurate.
755 However, we're changing a compile-time dependency (using the
756 REGISTER_NAMES macro) into a link- and run-time dependency
757 (calling REGISTER_NAME, which happens to be a function call on the
760 1999-01-22 Jim Lemke <jlemke@cygnus.com>
762 * igen.c(gen_semantics_[ch]): setup/use of new option

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

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

1169 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1170 works for normal and boolean table entries.
1172 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now

1233 determine the simulation speed by looking at the number of elapsed
1234 ticks recorded by the event queue.
1236 * psim.c (psim_write_register, psim_read_register): Force the cpu
1237 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1238 next cpu would be zero any way.
1240 * mon.c (mon_print_info): If possible, print the system cycle
1241 performance. This is an indication of the number of instructions
1244 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1246 * The code to allow an event queue to be updated during a signal
1247 was missing. For main.c, a cntrl-c simulation termination wasn't
1250 * The simulation would not correctly restart if an event requested
1251 that the simulation be halted.
1253 * psim.c (psim_options): Add hack to -i option to optionally
1254 include a level vis -i2.
1255 (psim_usage): Document.

1274 * gen-idecode.c (print_run_until_stop_body): Call
1275 event_queue_process_events to clear possibly pending events before
1276 starting a simulation run. Re-arange main loop so that simulator
1277 is correctly restarted when an event halts the simulation.

1303 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1304 to be initialized independant of the rest of the simulation
1305 initalization. Otherwize a trace option explictly set from gdb
1306 could be overridden by hw_trace.
1308 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1310 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1311 debug.c. It could be much simpler.
1313 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1329 string array - use the first entry for the initial file image.
1331 * tree.c (print_string_aray_property): New function - print a

1353 the form <name>_is_<const> where it is a boolean field, generate
1354 the result of the expression instead of the expression its self.

1356 then generating corresponding definitions.
1358 * gen-icache.c (print_icache_struct): If there is no cache, do not
1359 output expressions in idecode.h file.
1361 * gen-icache.c (print_icache_body): Output them here.
1363 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1368 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1370 * The code that put values in and extracted values from the cache
1371 was too compilicated. The cache table did not allow values to be
1372 computed from cache entries. #defines could only be used when a
1373 cache was present, remove the restriction.
1375 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1376 scratch variable is defined when a cache entry is beinf
1377 filled. Change the definition of a COMPUTE variable to be defined
1378 when the cache entry is being used.
1379 * gen-icache.c: Update.
1381 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1383 * gen-icache.c: Update
1385 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1386 different types of cache code - put into cache, extract from
1387 cache, no cache - an explicit argument to print_icache_body.

1390 * gen-semantics.c (print_c_semantic): Update use.
1391 * gen-idecode.c (print_jump_insn): Update use.
1392 * gen-icache.c (print_icache_function): Update use.
1394 * igen.c (main): Change 'R' option so that it does not force the
1397 * configure.in (enable-sim-icache): Clarify description. Make
1398 #define one of the defaults regardless of the cache. Probably
1399 should revamp and add a separate option.
1401 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1403 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
