796 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
798 * sim-endian.h: Don't have parameters on macro definitions which
799 are simply renaming functions, to permit use of XCONCAT2 in both
800 the macro name and the arguments in a use of such a definition.
802 2000-11-15 Jim Blandy <jimb@redhat.com>
804 * sim_calls.c: Doc fix.
805 (sim_fetch_register, sim_store_register): Call

840 1999-05-08 Felix Lee <flee@cygnus.com>
842 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.

845 1999-04-02 Keith Seitz <keiths@cygnus.com>

863 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
865 Make the simulator compatible with the MPC750. It would be nicer
866 to make this a real multi-sim, but that's more work than we have
868 * emul_generic.c (emul_add_tree_options): Only require strict
869 alignment if it was explicitly requested at configuration time.
870 Don't make it the default for little-endian machines.
871 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
872 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
873 THRM2, THRM3): Plop in the MPC750 SPR registers.
874 (DABR): This is weird. This was HID5, but the PPC spec says this
875 should be DABR; why did some random processor use it for something
876 else? The HID5 entry dates back to the original checkin of the
877 simulator code in 1995, so remove it.
878 * sim_calls.c (register_names): Delete this; since the user can
879 now change GDB's list of register names dynamically, we can't
880 pretend there's a static mapping here.
881 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
882 function to get the register name. That ought to be accurate.
883 However, we're changing a compile-time dependency (using the
884 REGISTER_NAMES macro) into a link- and run-time dependency
885 (calling REGISTER_NAME, which happens to be a function call on the
888 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

1361 determine the simulation speed by looking at the number of elapsed
1362 ticks recorded by the event queue.
1364 * psim.c (psim_write_register, psim_read_register): Force the cpu
1365 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1366 next cpu would be zero any way.
1368 * mon.c (mon_print_info): If possible, print the system cycle
1369 performance. This is an indication of the number of instructions
1372 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1374 * The code to allow an event queue to be updated during a signal
1375 was missing. For main.c, a cntrl-c simulation termination wasn't
1378 * The simulation would not correctly restart if an event requested
1379 that the simulation be halted.
1381 * psim.c (psim_options): Add hack to -i option to optionally
1382 include a level vis -i2.
1383 (psim_usage): Document.

1402 * gen-idecode.c (print_run_until_stop_body): Call
1403 event_queue_process_events to clear possibly pending events before
1404 starting a simulation run. Re-arange main loop so that simulator
1405 is correctly restarted when an event halts the simulation.

1431 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1432 to be initialized independant of the rest of the simulation
1433 initalization. Otherwize a trace option explictly set from gdb
1434 could be overridden by hw_trace.
1436 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1438 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1439 debug.c. It could be much simpler.

1457 string array - use the first entry for the initial file image.
1459 * tree.c (print_string_aray_property): New function - print a

1480 * gen-icache.c (print_icache_extraction): For a cache entry of
1481 the form <name>_is_<const> where it is a boolean field, generate
1482 the result of the expression instead of the expression its self.

1484 then generating corresponding definitions.
1486 * gen-icache.c (print_icache_struct): If there is no cache, do not
1487 output expressions in idecode.h file.
1489 * gen-icache.c (print_icache_body): Output them here.

1496 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1498 * The code that put values in and extracted values from the cache
1499 was too compilicated. The cache table did not allow values to be
1500 computed from cache entries. #defines could only be used when a
1501 cache was present, remove the restriction.
1503 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1504 scratch variable is defined when a cache entry is beinf
1505 filled. Change the definition of a COMPUTE variable to be defined
1506 when the cache entry is being used.
1507 * gen-icache.c: Update.
1509 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1511 * gen-icache.c: Update
1513 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1514 different types of cache code - put into cache, extract from
1515 cache, no cache - an explicit argument to print_icache_body.
1516 * gen-icache.c (print_icache_extraction): Ditto.
1518 * gen-semantics.c (print_c_semantic): Update use.
1519 * gen-idecode.c (print_jump_insn): Update use.
1520 * gen-icache.c (print_icache_function): Update use.
1522 * igen.c (main): Change 'R' option so that it does not force the
1525 * configure.in (enable-sim-icache): Clarify description. Make
1526 #define one of the defaults regardless of the cache. Probably
1527 should revamp and add a separate option.
1529 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1531 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1542 device after it was deleted. Instead add and remove cap's from the
1543 cap db as they are created and deleted. This ensuring that a
1544 capibility is only used during the lifetime of the corresponding
1547 * cap.h, cap.c: Correct cap type - was signed32 should be
1550 * cap.c (cap_add, cap_remove): New methods for cap object that
1551 allow the explicit addition and removal of internal objects that
1552 the cap knows about.
1554 * cap.c (cap_init): Rewrite. Verify that the only objects
1555 remaining in the cap data base are those that were entered first.
1556 Thse objects will be the permenant ones.
1557 * device.c (device_init_address): Remember to initialize the cap
1560 * device.c (device_create_instance_from): Explicitly add device
1561 instances to the cap database. Simplify create code.
