790 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
792 * sim-endian.h: Don't have parameters on macro definitions which
793 are simply renaming functions, to permit use of XCONCAT2 in both
794 the macro name and the arguments in a use of such a definition.
796 2000-11-15 Jim Blandy <jimb@redhat.com>
798 * sim_calls.c: Doc fix.
799 (sim_fetch_register, sim_store_register): Call

834 1999-05-08 Felix Lee <flee@cygnus.com>
836 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.

857 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
859 Make the simulator compatible with the MPC750. It would be nicer
860 to make this a real multi-sim, but that's more work than we have
862 * emul_generic.c (emul_add_tree_options): Only require strict
863 alignment if it was explicitly requested at configuration time.
864 Don't make it the default for little-endian machines.
865 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
866 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
867 THRM2, THRM3): Plop in the MPC750 SPR registers.
868 (DABR): This is weird. This was HID5, but the PPC spec says this
869 should be DABR; why did some random processor use it for something
870 else? The HID5 entry dates back to the original checkin of the
871 simulator code in 1995, so remove it.
872 * sim_calls.c (register_names): Delete this; since the user can
873 now change GDB's list of register names dynamically, we can't
874 pretend there's a static mapping here.
875 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
876 function to get the register name. That ought to be accurate.
877 However, we're changing a compile-time dependency (using the
878 REGISTER_NAMES macro) into a link- and run-time dependency
879 (calling REGISTER_NAME, which happens to be a function call on the
882 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

1042 mask extracting shift amount. Correctly condition for setting XER
1044 (ldhau): From Johannes Reisinger, update rA after load.

1355 determine the simulation speed by looking at the number of elapsed
1356 ticks recorded by the event queue.
1358 * psim.c (psim_write_register, psim_read_register): Force the cpu
1359 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1360 next cpu would be zero any way.
1362 * mon.c (mon_print_info): If possible, print the system cycle
1363 performance. This is an indication of the number of instructions
1366 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1368 * The code to allow an event queue to be updated during a signal
1369 was missing. For main.c, a cntrl-c simulation termination wasn't
1372 * The simulation would not correctly restart if an event requested
1373 that the simulation be halted.
1375 * psim.c (psim_options): Add hack to -i option to optionally
1376 include a level vis -i2.
1377 (psim_usage): Document.

1396 * gen-idecode.c (print_run_until_stop_body): Call
1397 event_queue_process_events to clear possibly pending events before
1398 starting a simulation run. Re-arange main loop so that simulator
1399 is correctly restarted when an event halts the simulation.

1425 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1426 to be initialized independant of the rest of the simulation
1427 initalization. Otherwize a trace option explictly set from gdb
1428 could be overridden by hw_trace.
1430 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1432 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1433 debug.c. It could be much simpler.
1435 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1451 string array - use the first entry for the initial file image.
1453 * tree.c (print_string_aray_property): New function - print a

1474 * gen-icache.c (print_icache_extraction): For a cache entry of
1475 the form <name>_is_<const> where it is a boolean field, generate
1476 the result of the expression instead of the expression its self.

1478 then generating corresponding definitions.
1480 * gen-icache.c (print_icache_struct): If there is no cache, do not
1481 output expressions in idecode.h file.
1483 * gen-icache.c (print_icache_body): Output them here.
1485 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1490 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1492 * The code that put values in and extracted values from the cache
1493 was too compilicated. The cache table did not allow values to be
1494 computed from cache entries. #defines could only be used when a
1495 cache was present, remove the restriction.
1497 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1498 scratch variable is defined when a cache entry is beinf
1499 filled. Change the definition of a COMPUTE variable to be defined
1500 when the cache entry is being used.
1501 * gen-icache.c: Update.
1503 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1505 * gen-icache.c: Update
1507 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1508 different types of cache code - put into cache, extract from
1509 cache, no cache - an explicit argument to print_icache_body.
1510 * gen-icache.c (print_icache_extraction): Ditto.
1512 * gen-semantics.c (print_c_semantic): Update use.
1513 * gen-idecode.c (print_jump_insn): Update use.
1514 * gen-icache.c (print_icache_function): Update use.
1516 * igen.c (main): Change 'R' option so that it does not force the
1519 * configure.in (enable-sim-icache): Clarify description. Make
1520 #define one of the defaults regardless of the cache. Probably
1521 should revamp and add a separate option.
1523 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1525 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1536 device after it was deleted. Instead add and remove cap's from the
1537 cap db as they are created and deleted. This ensuring that a
1538 capibility is only used during the lifetime of the corresponding
1541 * cap.h, cap.c: Correct cap type - was signed32 should be
1544 * cap.c (cap_add, cap_remove): New methods for cap object that
1545 allow the explicit addition and removal of internal objects that
1546 the cap knows about.
1548 * cap.c (cap_init): Rewrite. Verify that the only objects
1549 remaining in the cap data base are those that were entered first.
1550 Thse objects will be the permenant ones.
1551 * device.c (device_init_address): Remember to initialize the cap
1554 * device.c (device_create_instance_from): Explicitly add device
1555 instances to the cap database. Simplify create code.
