806 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
808 * sim-endian.h: Don't have parameters on macro definitions which
809 are simply renaming functions, to permit use of XCONCAT2 in both
810 the macro name and the arguments in a use of such a definition.
812 2000-11-15 Jim Blandy <jimb@redhat.com>
814 * sim_calls.c: Doc fix.
815 (sim_fetch_register, sim_store_register): Call

850 1999-05-08 Felix Lee <flee@cygnus.com>
852 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.

873 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
875 Make the simulator compatible with the MPC750. It would be nicer
876 to make this a real multi-sim, but that's more work than we have
878 * emul_generic.c (emul_add_tree_options): Only require strict
879 alignment if it was explicitly requested at configuration time.
880 Don't make it the default for little-endian machines.
881 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
882 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
883 THRM2, THRM3): Plop in the MPC750 SPR registers.
884 (DABR): This is weird. This was HID5, but the PPC spec says this
885 should be DABR; why did some random processor use it for something
886 else? The HID5 entry dates back to the original checkin of the
887 simulator code in 1995, so remove it.
888 * sim_calls.c (register_names): Delete this; since the user can
889 now change GDB's list of register names dynamically, we can't
890 pretend there's a static mapping here.
891 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
892 function to get the register name. That ought to be accurate.
893 However, we're changing a compile-time dependency (using the
894 REGISTER_NAMES macro) into a link- and run-time dependency
895 (calling REGISTER_NAME, which happens to be a function call on the
898 1999-01-22 Jim Lemke <jlemke@cygnus.com>

905 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

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

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

1371 determine the simulation speed by looking at the number of elapsed
1372 ticks recorded by the event queue.
1374 * psim.c (psim_write_register, psim_read_register): Force the cpu
1375 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1376 next cpu would be zero any way.
1378 * mon.c (mon_print_info): If possible, print the system cycle
1379 performance. This is an indication of the number of instructions
1382 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1384 * The code to allow an event queue to be updated during a signal
1385 was missing. For main.c, a cntrl-c simulation termination wasn't
1388 * The simulation would not correctly restart if an event requested
1389 that the simulation be halted.
1391 * psim.c (psim_options): Add hack to -i option to optionally
1392 include a level vis -i2.
1393 (psim_usage): Document.

1412 * gen-idecode.c (print_run_until_stop_body): Call
1413 event_queue_process_events to clear possibly pending events before
1414 starting a simulation run. Re-arange main loop so that simulator
1415 is correctly restarted when an event halts the simulation.

1441 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1442 to be initialized independant of the rest of the simulation
1443 initalization. Otherwize a trace option explictly set from gdb
1444 could be overridden by hw_trace.
1446 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1448 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1449 debug.c. It could be much simpler.

1467 string array - use the first entry for the initial file image.
1469 * tree.c (print_string_aray_property): New function - print a

1490 * gen-icache.c (print_icache_extraction): For a cache entry of
1491 the form <name>_is_<const> where it is a boolean field, generate
1492 the result of the expression instead of the expression its self.

1494 then generating corresponding definitions.
1496 * gen-icache.c (print_icache_struct): If there is no cache, do not
1497 output expressions in idecode.h file.
1499 * gen-icache.c (print_icache_body): Output them here.
1501 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1506 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1508 * The code that put values in and extracted values from the cache
1509 was too compilicated. The cache table did not allow values to be
1510 computed from cache entries. #defines could only be used when a
1511 cache was present, remove the restriction.
1513 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1514 scratch variable is defined when a cache entry is beinf
1515 filled. Change the definition of a COMPUTE variable to be defined
1516 when the cache entry is being used.
1517 * gen-icache.c: Update.
1519 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1521 * gen-icache.c: Update
1523 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1524 different types of cache code - put into cache, extract from
1525 cache, no cache - an explicit argument to print_icache_body.
1526 * gen-icache.c (print_icache_extraction): Ditto.
1528 * gen-semantics.c (print_c_semantic): Update use.
1529 * gen-idecode.c (print_jump_insn): Update use.
1530 * gen-icache.c (print_icache_function): Update use.
1532 * igen.c (main): Change 'R' option so that it does not force the
1535 * configure.in (enable-sim-icache): Clarify description. Make
1536 #define one of the defaults regardless of the cache. Probably
1537 should revamp and add a separate option.
1539 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1541 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1552 device after it was deleted. Instead add and remove cap's from the
1553 cap db as they are created and deleted. This ensuring that a
1554 capibility is only used during the lifetime of the corresponding
1557 * cap.h, cap.c: Correct cap type - was signed32 should be
1560 * cap.c (cap_add, cap_remove): New methods for cap object that
1561 allow the explicit addition and removal of internal objects that
1562 the cap knows about.
1564 * cap.c (cap_init): Rewrite. Verify that the only objects
1565 remaining in the cap data base are those that were entered first.
1566 Thse objects will be the permenant ones.
1567 * device.c (device_init_address): Remember to initialize the cap
1570 * device.c (device_create_instance_from): Explicitly add device
1571 instances to the cap database. Simplify create code.
