757 are simply renaming functions, to permit use of XCONCAT2 in both
758 the macro name and the arguments in a use of such a definition.
760 2000-11-15 Jim Blandy <jimb@redhat.com>
762 * sim_calls.c: Doc fix.
763 (sim_fetch_register, sim_store_register): Call

798 1999-05-08 Felix Lee <flee@cygnus.com>
800 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
801 * configure: Regenerated to track ../common/aclocal.m4 changes.
803 1999-04-02 Keith Seitz <keiths@cygnus.com>

809 after the specified POLL_QUIT_INTERVAL.
811 1999-02-22 Jim Lemke <jlemke@cygnus.com>
813 * dc-complex: Force expansion on all bits of field BO.

821 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
823 Make the simulator compatible with the MPC750. It would be nicer
824 to make this a real multi-sim, but that's more work than we have
826 * emul_generic.c (emul_add_tree_options): Only require strict
827 alignment if it was explicitly requested at configuration time.
828 Don't make it the default for little-endian machines.
829 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
830 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
831 THRM2, THRM3): Plop in the MPC750 SPR registers.
832 (DABR): This is weird. This was HID5, but the PPC spec says this
833 should be DABR; why did some random processor use it for something
834 else? The HID5 entry dates back to the original checkin of the
835 simulator code in 1995, so remove it.
836 * sim_calls.c (register_names): Delete this; since the user can
837 now change GDB's list of register names dynamically, we can't
838 pretend there's a static mapping here.
839 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
840 function to get the register name. That ought to be accurate.
841 However, we're changing a compile-time dependency (using the
842 REGISTER_NAMES macro) into a link- and run-time dependency
843 (calling REGISTER_NAME, which happens to be a function call on the
846 1999-01-22 Jim Lemke <jlemke@cygnus.com>

853 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

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

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

1008 (ldhau): From Johannes Reisinger, update rA after load.
1010 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
1012 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,
1014 * words.h: __int64 instead of long long for MSVC.
1016 Wed Aug 27 10:24:15 1997 Andrew Cagney <cagney@b1.cygnus.com>

1319 determine the simulation speed by looking at the number of elapsed
1320 ticks recorded by the event queue.
1322 * psim.c (psim_write_register, psim_read_register): Force the cpu
1323 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1324 next cpu would be zero any way.
1326 * mon.c (mon_print_info): If possible, print the system cycle
1327 performance. This is an indication of the number of instructions
1330 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1332 * The code to allow an event queue to be updated during a signal
1333 was missing. For main.c, a cntrl-c simulation termination wasn't
1336 * The simulation would not correctly restart if an event requested
1337 that the simulation be halted.
1339 * psim.c (psim_options): Add hack to -i option to optionally
1340 include a level vis -i2.
1341 (psim_usage): Document.

1360 * gen-idecode.c (print_run_until_stop_body): Call
1361 event_queue_process_events to clear possibly pending events before
1362 starting a simulation run. Re-arange main loop so that simulator
1363 is correctly restarted when an event halts the simulation.

1389 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1390 to be initialized independant of the rest of the simulation
1391 initalization. Otherwize a trace option explictly set from gdb
1392 could be overridden by hw_trace.
1394 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1396 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1397 debug.c. It could be much simpler.

1439 the form <name>_is_<const> where it is a boolean field, generate
1440 the result of the expression instead of the expression its self.

1442 then generating corresponding definitions.
1444 * gen-icache.c (print_icache_struct): If there is no cache, do not
1445 output expressions in idecode.h file.
1447 * gen-icache.c (print_icache_body): Output them here.
1449 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1456 * The code that put values in and extracted values from the cache
1457 was too compilicated. The cache table did not allow values to be
1458 computed from cache entries. #defines could only be used when a
1459 cache was present, remove the restriction.
1461 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1462 scratch variable is defined when a cache entry is beinf
1463 filled. Change the definition of a COMPUTE variable to be defined
1464 when the cache entry is being used.
1465 * gen-icache.c: Update.
1467 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1472 different types of cache code - put into cache, extract from
1473 cache, no cache - an explicit argument to print_icache_body.
1474 * gen-icache.c (print_icache_extraction): Ditto.
1476 * gen-semantics.c (print_c_semantic): Update use.
1477 * gen-idecode.c (print_jump_insn): Update use.
1478 * gen-icache.c (print_icache_function): Update use.
1480 * igen.c (main): Change 'R' option so that it does not force the
1483 * configure.in (enable-sim-icache): Clarify description. Make
1484 #define one of the defaults regardless of the cache. Probably
1485 should revamp and add a separate option.
1487 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1489 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1500 device after it was deleted. Instead add and remove cap's from the
1501 cap db as they are created and deleted. This ensuring that a
1502 capibility is only used during the lifetime of the corresponding
