763 are simply renaming functions, to permit use of XCONCAT2 in both
764 the macro name and the arguments in a use of such a definition.
766 2000-11-15 Jim Blandy <jimb@redhat.com>
768 * sim_calls.c: Doc fix.
769 (sim_fetch_register, sim_store_register): Call

804 1999-05-08 Felix Lee <flee@cygnus.com>
806 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
807 * configure: Regenerated to track ../common/aclocal.m4 changes.
809 1999-04-02 Keith Seitz <keiths@cygnus.com>

827 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
829 Make the simulator compatible with the MPC750. It would be nicer
830 to make this a real multi-sim, but that's more work than we have
832 * emul_generic.c (emul_add_tree_options): Only require strict
833 alignment if it was explicitly requested at configuration time.
834 Don't make it the default for little-endian machines.
835 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
836 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
837 THRM2, THRM3): Plop in the MPC750 SPR registers.
838 (DABR): This is weird. This was HID5, but the PPC spec says this
839 should be DABR; why did some random processor use it for something
840 else? The HID5 entry dates back to the original checkin of the
841 simulator code in 1995, so remove it.
842 * sim_calls.c (register_names): Delete this; since the user can
843 now change GDB's list of register names dynamically, we can't
844 pretend there's a static mapping here.
845 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
846 function to get the register name. That ought to be accurate.
847 However, we're changing a compile-time dependency (using the
848 REGISTER_NAMES macro) into a link- and run-time dependency
849 (calling REGISTER_NAME, which happens to be a function call on the
852 1999-01-22 Jim Lemke <jlemke@cygnus.com>

859 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

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

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

1014 (ldhau): From Johannes Reisinger, update rA after load.
1016 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
1018 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,
1020 * words.h: __int64 instead of long long for MSVC.

1325 determine the simulation speed by looking at the number of elapsed
1326 ticks recorded by the event queue.
1328 * psim.c (psim_write_register, psim_read_register): Force the cpu
1329 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1330 next cpu would be zero any way.
1332 * mon.c (mon_print_info): If possible, print the system cycle
1333 performance. This is an indication of the number of instructions
1336 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1338 * The code to allow an event queue to be updated during a signal
1339 was missing. For main.c, a cntrl-c simulation termination wasn't
1342 * The simulation would not correctly restart if an event requested
1343 that the simulation be halted.
1345 * psim.c (psim_options): Add hack to -i option to optionally
1346 include a level vis -i2.
1347 (psim_usage): Document.

1366 * gen-idecode.c (print_run_until_stop_body): Call
1367 event_queue_process_events to clear possibly pending events before
1368 starting a simulation run. Re-arange main loop so that simulator
1369 is correctly restarted when an event halts the simulation.

1395 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1396 to be initialized independant of the rest of the simulation
1397 initalization. Otherwize a trace option explictly set from gdb
1398 could be overridden by hw_trace.
1400 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1402 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1403 debug.c. It could be much simpler.
1405 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1421 string array - use the first entry for the initial file image.
1423 * tree.c (print_string_aray_property): New function - print a
1425 (print_properties): Adjust.

1444 * gen-icache.c (print_icache_extraction): For a cache entry of
1445 the form <name>_is_<const> where it is a boolean field, generate
1446 the result of the expression instead of the expression its self.

1448 then generating corresponding definitions.
1450 * gen-icache.c (print_icache_struct): If there is no cache, do not
1451 output expressions in idecode.h file.
1453 * gen-icache.c (print_icache_body): Output them here.
1455 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1462 * The code that put values in and extracted values from the cache
1463 was too compilicated. The cache table did not allow values to be
1464 computed from cache entries. #defines could only be used when a
1465 cache was present, remove the restriction.
1467 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1468 scratch variable is defined when a cache entry is beinf
1469 filled. Change the definition of a COMPUTE variable to be defined
1470 when the cache entry is being used.
1471 * gen-icache.c: Update.
1473 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1475 * gen-icache.c: Update
1477 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1478 different types of cache code - put into cache, extract from
1479 cache, no cache - an explicit argument to print_icache_body.
1480 * gen-icache.c (print_icache_extraction): Ditto.
1482 * gen-semantics.c (print_c_semantic): Update use.
1483 * gen-idecode.c (print_jump_insn): Update use.
1484 * gen-icache.c (print_icache_function): Update use.
1486 * igen.c (main): Change 'R' option so that it does not force the
1489 * configure.in (enable-sim-icache): Clarify description. Make
1490 #define one of the defaults regardless of the cache. Probably
1491 should revamp and add a separate option.
1493 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1495 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1506 device after it was deleted. Instead add and remove cap's from the
1507 cap db as they are created and deleted. This ensuring that a
1508 capibility is only used during the lifetime of the corresponding
1511 * cap.h, cap.c: Correct cap type - was signed32 should be
1514 * cap.c (cap_add, cap_remove): New methods for cap object that
1515 allow the explicit addition and removal of internal objects that
1516 the cap knows about.
1518 * cap.c (cap_init): Rewrite. Verify that the only objects
1519 remaining in the cap data base are those that were entered first.
1520 Thse objects will be the permenant ones.
1521 * device.c (device_init_address): Remember to initialize the cap
1524 * device.c (device_create_instance_from): Explicitly add device
1525 instances to the cap database. Simplify create code.
