800 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
802 * sim-endian.h: Don't have parameters on macro definitions which
803 are simply renaming functions, to permit use of XCONCAT2 in both
804 the macro name and the arguments in a use of such a definition.
806 2000-11-15 Jim Blandy <jimb@redhat.com>
808 * sim_calls.c: Doc fix.
809 (sim_fetch_register, sim_store_register): Call

844 1999-05-08 Felix Lee <flee@cygnus.com>
846 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.

867 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
869 Make the simulator compatible with the MPC750. It would be nicer
870 to make this a real multi-sim, but that's more work than we have
872 * emul_generic.c (emul_add_tree_options): Only require strict
873 alignment if it was explicitly requested at configuration time.
874 Don't make it the default for little-endian machines.
875 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
876 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
877 THRM2, THRM3): Plop in the MPC750 SPR registers.
878 (DABR): This is weird. This was HID5, but the PPC spec says this
879 should be DABR; why did some random processor use it for something
880 else? The HID5 entry dates back to the original checkin of the
881 simulator code in 1995, so remove it.
882 * sim_calls.c (register_names): Delete this; since the user can
883 now change GDB's list of register names dynamically, we can't
884 pretend there's a static mapping here.
885 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
886 function to get the register name. That ought to be accurate.
887 However, we're changing a compile-time dependency (using the
888 REGISTER_NAMES macro) into a link- and run-time dependency
889 (calling REGISTER_NAME, which happens to be a function call on the
892 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

1365 determine the simulation speed by looking at the number of elapsed
1366 ticks recorded by the event queue.
1368 * psim.c (psim_write_register, psim_read_register): Force the cpu
1369 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1370 next cpu would be zero any way.
1372 * mon.c (mon_print_info): If possible, print the system cycle
1373 performance. This is an indication of the number of instructions
1376 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1378 * The code to allow an event queue to be updated during a signal
1379 was missing. For main.c, a cntrl-c simulation termination wasn't
1382 * The simulation would not correctly restart if an event requested
1383 that the simulation be halted.
1385 * psim.c (psim_options): Add hack to -i option to optionally
1386 include a level vis -i2.
1387 (psim_usage): Document.

1406 * gen-idecode.c (print_run_until_stop_body): Call
1407 event_queue_process_events to clear possibly pending events before
1408 starting a simulation run. Re-arange main loop so that simulator
1409 is correctly restarted when an event halts the simulation.

1435 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1436 to be initialized independant of the rest of the simulation
1437 initalization. Otherwize a trace option explictly set from gdb
1438 could be overridden by hw_trace.
1440 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1442 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1443 debug.c. It could be much simpler.

1461 string array - use the first entry for the initial file image.
1463 * tree.c (print_string_aray_property): New function - print a

1484 * gen-icache.c (print_icache_extraction): For a cache entry of
1485 the form <name>_is_<const> where it is a boolean field, generate
1486 the result of the expression instead of the expression its self.

1488 then generating corresponding definitions.
1490 * gen-icache.c (print_icache_struct): If there is no cache, do not
1491 output expressions in idecode.h file.
1493 * gen-icache.c (print_icache_body): Output them here.

1502 * The code that put values in and extracted values from the cache
1503 was too compilicated. The cache table did not allow values to be
1504 computed from cache entries. #defines could only be used when a
1505 cache was present, remove the restriction.
1507 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1508 scratch variable is defined when a cache entry is beinf
1509 filled. Change the definition of a COMPUTE variable to be defined
1510 when the cache entry is being used.
1511 * gen-icache.c: Update.
1513 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1518 different types of cache code - put into cache, extract from
1519 cache, no cache - an explicit argument to print_icache_body.
1520 * gen-icache.c (print_icache_extraction): Ditto.
1522 * gen-semantics.c (print_c_semantic): Update use.
1523 * gen-idecode.c (print_jump_insn): Update use.
1524 * gen-icache.c (print_icache_function): Update use.
1526 * igen.c (main): Change 'R' option so that it does not force the
1529 * configure.in (enable-sim-icache): Clarify description. Make
1530 #define one of the defaults regardless of the cache. Probably
1531 should revamp and add a separate option.
1533 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1535 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1546 device after it was deleted. Instead add and remove cap's from the
1547 cap db as they are created and deleted. This ensuring that a
1548 capibility is only used during the lifetime of the corresponding
1551 * cap.h, cap.c: Correct cap type - was signed32 should be
1554 * cap.c (cap_add, cap_remove): New methods for cap object that
1555 allow the explicit addition and removal of internal objects that
1556 the cap knows about.
1558 * cap.c (cap_init): Rewrite. Verify that the only objects
1559 remaining in the cap data base are those that were entered first.
1560 Thse objects will be the permenant ones.
1561 * device.c (device_init_address): Remember to initialize the cap
1564 * device.c (device_create_instance_from): Explicitly add device
1565 instances to the cap database. Simplify create code.
