684 are simply renaming functions, to permit use of XCONCAT2 in both
685 the macro name and the arguments in a use of such a definition.
687 2000-11-15 Jim Blandy <jimb@redhat.com>
689 * sim_calls.c: Doc fix.
690 (sim_fetch_register, sim_store_register): Call

725 1999-05-08 Felix Lee <flee@cygnus.com>
727 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
728 * configure: Regenerated to track ../common/aclocal.m4 changes.
730 1999-04-02 Keith Seitz <keiths@cygnus.com>

748 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
750 Make the simulator compatible with the MPC750. It would be nicer
751 to make this a real multi-sim, but that's more work than we have
753 * emul_generic.c (emul_add_tree_options): Only require strict
754 alignment if it was explicitly requested at configuration time.
755 Don't make it the default for little-endian machines.
756 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
757 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
758 THRM2, THRM3): Plop in the MPC750 SPR registers.
759 (DABR): This is weird. This was HID5, but the PPC spec says this
760 should be DABR; why did some random processor use it for something
761 else? The HID5 entry dates back to the original checkin of the
762 simulator code in 1995, so remove it.
763 * sim_calls.c (register_names): Delete this; since the user can
764 now change GDB's list of register names dynamically, we can't
765 pretend there's a static mapping here.
766 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
767 function to get the register name. That ought to be accurate.
768 However, we're changing a compile-time dependency (using the
769 REGISTER_NAMES macro) into a link- and run-time dependency
770 (calling REGISTER_NAME, which happens to be a function call on the
773 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

1246 determine the simulation speed by looking at the number of elapsed
1247 ticks recorded by the event queue.
1249 * psim.c (psim_write_register, psim_read_register): Force the cpu
1250 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1251 next cpu would be zero any way.
1253 * mon.c (mon_print_info): If possible, print the system cycle
1254 performance. This is an indication of the number of instructions
1257 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1259 * The code to allow an event queue to be updated during a signal
1260 was missing. For main.c, a cntrl-c simulation termination wasn't
1263 * The simulation would not correctly restart if an event requested
1264 that the simulation be halted.
1266 * psim.c (psim_options): Add hack to -i option to optionally
1267 include a level vis -i2.
1268 (psim_usage): Document.

1287 * gen-idecode.c (print_run_until_stop_body): Call
1288 event_queue_process_events to clear possibly pending events before
1289 starting a simulation run. Re-arange main loop so that simulator
1290 is correctly restarted when an event halts the simulation.

1316 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1317 to be initialized independant of the rest of the simulation
1318 initalization. Otherwize a trace option explictly set from gdb
1319 could be overridden by hw_trace.
1321 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1323 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1324 debug.c. It could be much simpler.
1326 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1342 string array - use the first entry for the initial file image.
1344 * tree.c (print_string_aray_property): New function - print a

1366 the form <name>_is_<const> where it is a boolean field, generate
1367 the result of the expression instead of the expression its self.

1369 then generating corresponding definitions.
1371 * gen-icache.c (print_icache_struct): If there is no cache, do not
1372 output expressions in idecode.h file.
1374 * gen-icache.c (print_icache_body): Output them here.
1376 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1383 * The code that put values in and extracted values from the cache
1384 was too compilicated. The cache table did not allow values to be
1385 computed from cache entries. #defines could only be used when a
1386 cache was present, remove the restriction.
1388 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1389 scratch variable is defined when a cache entry is beinf
1390 filled. Change the definition of a COMPUTE variable to be defined
1391 when the cache entry is being used.
1392 * gen-icache.c: Update.
1394 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1403 * gen-semantics.c (print_c_semantic): Update use.
1404 * gen-idecode.c (print_jump_insn): Update use.
1405 * gen-icache.c (print_icache_function): Update use.
1407 * igen.c (main): Change 'R' option so that it does not force the
1410 * configure.in (enable-sim-icache): Clarify description. Make
1411 #define one of the defaults regardless of the cache. Probably
1412 should revamp and add a separate option.
1414 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
