693 are simply renaming functions, to permit use of XCONCAT2 in both
694 the macro name and the arguments in a use of such a definition.
696 2000-11-15 Jim Blandy <jimb@redhat.com>
698 * sim_calls.c: Doc fix.
699 (sim_fetch_register, sim_store_register): Call

734 1999-05-08 Felix Lee <flee@cygnus.com>
736 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
737 * configure: Regenerated to track ../common/aclocal.m4 changes.
739 1999-04-02 Keith Seitz <keiths@cygnus.com>

757 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
759 Make the simulator compatible with the MPC750. It would be nicer
760 to make this a real multi-sim, but that's more work than we have
762 * emul_generic.c (emul_add_tree_options): Only require strict
763 alignment if it was explicitly requested at configuration time.
764 Don't make it the default for little-endian machines.
765 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
766 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
767 THRM2, THRM3): Plop in the MPC750 SPR registers.
768 (DABR): This is weird. This was HID5, but the PPC spec says this
769 should be DABR; why did some random processor use it for something
770 else? The HID5 entry dates back to the original checkin of the
771 simulator code in 1995, so remove it.
772 * sim_calls.c (register_names): Delete this; since the user can
773 now change GDB's list of register names dynamically, we can't
774 pretend there's a static mapping here.
775 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
776 function to get the register name. That ought to be accurate.
777 However, we're changing a compile-time dependency (using the
778 REGISTER_NAMES macro) into a link- and run-time dependency
779 (calling REGISTER_NAME, which happens to be a function call on the
782 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

1255 determine the simulation speed by looking at the number of elapsed
1256 ticks recorded by the event queue.
1258 * psim.c (psim_write_register, psim_read_register): Force the cpu
1259 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1260 next cpu would be zero any way.
1262 * mon.c (mon_print_info): If possible, print the system cycle
1263 performance. This is an indication of the number of instructions
1266 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1268 * The code to allow an event queue to be updated during a signal
1269 was missing. For main.c, a cntrl-c simulation termination wasn't
1272 * The simulation would not correctly restart if an event requested
1273 that the simulation be halted.
1275 * psim.c (psim_options): Add hack to -i option to optionally
1276 include a level vis -i2.
1277 (psim_usage): Document.

1296 * gen-idecode.c (print_run_until_stop_body): Call
1297 event_queue_process_events to clear possibly pending events before
1298 starting a simulation run. Re-arange main loop so that simulator
1299 is correctly restarted when an event halts the simulation.

1325 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1326 to be initialized independant of the rest of the simulation
1327 initalization. Otherwize a trace option explictly set from gdb
1328 could be overridden by hw_trace.
1330 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1332 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1333 debug.c. It could be much simpler.
1335 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1351 string array - use the first entry for the initial file image.
1353 * tree.c (print_string_aray_property): New function - print a

1375 the form <name>_is_<const> where it is a boolean field, generate
1376 the result of the expression instead of the expression its self.

1378 then generating corresponding definitions.
1380 * gen-icache.c (print_icache_struct): If there is no cache, do not
1381 output expressions in idecode.h file.
1383 * gen-icache.c (print_icache_body): Output them here.
1385 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1392 * The code that put values in and extracted values from the cache
1393 was too compilicated. The cache table did not allow values to be
1394 computed from cache entries. #defines could only be used when a
1395 cache was present, remove the restriction.
1397 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1398 scratch variable is defined when a cache entry is beinf
1399 filled. Change the definition of a COMPUTE variable to be defined
1400 when the cache entry is being used.
1401 * gen-icache.c: Update.
1403 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1412 * gen-semantics.c (print_c_semantic): Update use.
1413 * gen-idecode.c (print_jump_insn): Update use.
1414 * gen-icache.c (print_icache_function): Update use.
1416 * igen.c (main): Change 'R' option so that it does not force the
1419 * configure.in (enable-sim-icache): Clarify description. Make
1420 #define one of the defaults regardless of the cache. Probably
1421 should revamp and add a separate option.
1423 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1425 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
