752 are simply renaming functions, to permit use of XCONCAT2 in both
753 the macro name and the arguments in a use of such a definition.
755 2000-11-15 Jim Blandy <jimb@redhat.com>
757 * sim_calls.c: Doc fix.
758 (sim_fetch_register, sim_store_register): Call

793 1999-05-08 Felix Lee <flee@cygnus.com>
795 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
796 * configure: Regenerated to track ../common/aclocal.m4 changes.
798 1999-04-02 Keith Seitz <keiths@cygnus.com>

816 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
818 Make the simulator compatible with the MPC750. It would be nicer
819 to make this a real multi-sim, but that's more work than we have
821 * emul_generic.c (emul_add_tree_options): Only require strict
822 alignment if it was explicitly requested at configuration time.
823 Don't make it the default for little-endian machines.
824 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
825 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
826 THRM2, THRM3): Plop in the MPC750 SPR registers.
827 (DABR): This is weird. This was HID5, but the PPC spec says this
828 should be DABR; why did some random processor use it for something
829 else? The HID5 entry dates back to the original checkin of the
830 simulator code in 1995, so remove it.
831 * sim_calls.c (register_names): Delete this; since the user can
832 now change GDB's list of register names dynamically, we can't
833 pretend there's a static mapping here.
834 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
835 function to get the register name. That ought to be accurate.
836 However, we're changing a compile-time dependency (using the
837 REGISTER_NAMES macro) into a link- and run-time dependency
838 (calling REGISTER_NAME, which happens to be a function call on the
841 1999-01-22 Jim Lemke <jlemke@cygnus.com>

848 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
850 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
852 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

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

892 * sim_calls.c (sim_fetch_register, sim_store_register):
893 return zero when nothing to do.

897 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
898 * configure: Regenerate.
899 * emul_{netbsd,unix}.c (toplevel): No longer try to include
900 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
902 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
904 * Makefile.in: The run target depended on a target psim$(EXEEXT),
905 but there was no such target, only plain psim. So I changed the
906 run target to depend on psim.
908 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
910 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
911 now defined in ../common/aclocal.m4, and the double definition causes
912 problems with AC_SUBST of EXEEXT.

1003 (ldhau): From Johannes Reisinger, update rA after load.
1005 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
1007 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,
1009 * words.h: __int64 instead of long long for MSVC.
1011 Wed Aug 27 10:24:15 1997 Andrew Cagney <cagney@b1.cygnus.com>

1314 determine the simulation speed by looking at the number of elapsed
1315 ticks recorded by the event queue.
1317 * psim.c (psim_write_register, psim_read_register): Force the cpu
1318 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1319 next cpu would be zero any way.
1321 * mon.c (mon_print_info): If possible, print the system cycle
1322 performance. This is an indication of the number of instructions
1325 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1327 * The code to allow an event queue to be updated during a signal
1328 was missing. For main.c, a cntrl-c simulation termination wasn't
1331 * The simulation would not correctly restart if an event requested
1332 that the simulation be halted.
1334 * psim.c (psim_options): Add hack to -i option to optionally
1335 include a level vis -i2.
1336 (psim_usage): Document.

1355 * gen-idecode.c (print_run_until_stop_body): Call
1356 event_queue_process_events to clear possibly pending events before
1357 starting a simulation run. Re-arange main loop so that simulator
1358 is correctly restarted when an event halts the simulation.

1384 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1385 to be initialized independant of the rest of the simulation
1386 initalization. Otherwize a trace option explictly set from gdb
1387 could be overridden by hw_trace.
1389 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1391 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1392 debug.c. It could be much simpler.
1394 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1410 string array - use the first entry for the initial file image.
1412 * tree.c (print_string_aray_property): New function - print a

1434 the form <name>_is_<const> where it is a boolean field, generate
1435 the result of the expression instead of the expression its self.

1451 * The code that put values in and extracted values from the cache
1452 was too compilicated. The cache table did not allow values to be
1453 computed from cache entries. #defines could only be used when a
1454 cache was present, remove the restriction.
1456 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1457 scratch variable is defined when a cache entry is beinf
1458 filled. Change the definition of a COMPUTE variable to be defined
1459 when the cache entry is being used.
1460 * gen-icache.c: Update.
1462 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1471 * gen-semantics.c (print_c_semantic): Update use.
1472 * gen-idecode.c (print_jump_insn): Update use.
1473 * gen-icache.c (print_icache_function): Update use.
1475 * igen.c (main): Change 'R' option so that it does not force the
1478 * configure.in (enable-sim-icache): Clarify description. Make
1479 #define one of the defaults regardless of the cache. Probably
1480 should revamp and add a separate option.
1482 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1484 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
