816 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
818 * sim-endian.h: Don't have parameters on macro definitions which
819 are simply renaming functions, to permit use of XCONCAT2 in both
820 the macro name and the arguments in a use of such a definition.
822 2000-11-15 Jim Blandy <jimb@redhat.com>
824 * sim_calls.c: Doc fix.
825 (sim_fetch_register, sim_store_register): Call

860 1999-05-08 Felix Lee <flee@cygnus.com>
862 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
863 * configure: Regenerated to track ../common/aclocal.m4 changes.
865 1999-04-02 Keith Seitz <keiths@cygnus.com>

873 1999-02-22 Jim Lemke <jlemke@cygnus.com>
875 * dc-complex: Force expansion on all bits of field BO.

883 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
885 Make the simulator compatible with the MPC750. It would be nicer
886 to make this a real multi-sim, but that's more work than we have
888 * emul_generic.c (emul_add_tree_options): Only require strict
889 alignment if it was explicitly requested at configuration time.
890 Don't make it the default for little-endian machines.
891 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
892 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
893 THRM2, THRM3): Plop in the MPC750 SPR registers.
894 (DABR): This is weird. This was HID5, but the PPC spec says this
895 should be DABR; why did some random processor use it for something
896 else? The HID5 entry dates back to the original checkin of the
897 simulator code in 1995, so remove it.
898 * sim_calls.c (register_names): Delete this; since the user can
899 now change GDB's list of register names dynamically, we can't
900 pretend there's a static mapping here.
901 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
902 function to get the register name. That ought to be accurate.
903 However, we're changing a compile-time dependency (using the
904 REGISTER_NAMES macro) into a link- and run-time dependency
905 (calling REGISTER_NAME, which happens to be a function call on the
908 1999-01-22 Jim Lemke <jlemke@cygnus.com>
910 * igen.c(gen_semantics_[ch]): setup/use of new option

914 psim.c(is_num - added, psim_options): Parse and init new option.
915 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

932 1998-11-19 Michael Meissner <meissner@cygnus.com>
934 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
935 fractional type, so that quiet NaN's aren't treated like
938 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
940 * table.c (table_open): For cygwin hosts, we need to use the
941 return value from the read routine as the number of bytes to
942 process. This apparently is due to text-mode vs binary-mode. If
943 the mounts are done text-mode, then the size returnedby fstat()
944 may be different than the number of bytes "read" in text mode.
946 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
948 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

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

1381 determine the simulation speed by looking at the number of elapsed
1382 ticks recorded by the event queue.
1384 * psim.c (psim_write_register, psim_read_register): Force the cpu
1385 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1386 next cpu would be zero any way.
1388 * mon.c (mon_print_info): If possible, print the system cycle
1389 performance. This is an indication of the number of instructions
1392 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1394 * The code to allow an event queue to be updated during a signal
1395 was missing. For main.c, a cntrl-c simulation termination wasn't
1398 * The simulation would not correctly restart if an event requested
1399 that the simulation be halted.
1401 * psim.c (psim_options): Add hack to -i option to optionally
1402 include a level vis -i2.
1403 (psim_usage): Document.

1422 * gen-idecode.c (print_run_until_stop_body): Call
1423 event_queue_process_events to clear possibly pending events before
1424 starting a simulation run. Re-arange main loop so that simulator
1425 is correctly restarted when an event halts the simulation.

1451 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1452 to be initialized independant of the rest of the simulation
1453 initalization. Otherwize a trace option explictly set from gdb
1454 could be overridden by hw_trace.
1456 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1458 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1459 debug.c. It could be much simpler.

1477 string array - use the first entry for the initial file image.
1479 * tree.c (print_string_aray_property): New function - print a

1500 * gen-icache.c (print_icache_extraction): For a cache entry of
1501 the form <name>_is_<const> where it is a boolean field, generate
1502 the result of the expression instead of the expression its self.

1504 then generating corresponding definitions.
1506 * gen-icache.c (print_icache_struct): If there is no cache, do not
1507 output expressions in idecode.h file.
1509 * gen-icache.c (print_icache_body): Output them here.
1511 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1516 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1518 * The code that put values in and extracted values from the cache
1519 was too compilicated. The cache table did not allow values to be
1520 computed from cache entries. #defines could only be used when a
1521 cache was present, remove the restriction.
1523 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1524 scratch variable is defined when a cache entry is beinf
1525 filled. Change the definition of a COMPUTE variable to be defined
1526 when the cache entry is being used.
1527 * gen-icache.c: Update.
1529 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1530 is more obvious. old_name->field_name, new_name->derived_name.
1531 * gen-icache.c: Update
1533 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1534 different types of cache code - put into cache, extract from
1535 cache, no cache - an explicit argument to print_icache_body.
1536 * gen-icache.c (print_icache_extraction): Ditto.
1538 * gen-semantics.c (print_c_semantic): Update use.
1539 * gen-idecode.c (print_jump_insn): Update use.
1540 * gen-icache.c (print_icache_function): Update use.
1542 * igen.c (main): Change 'R' option so that it does not force the
1545 * configure.in (enable-sim-icache): Clarify description. Make
1546 #define one of the defaults regardless of the cache. Probably
1547 should revamp and add a separate option.
1549 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1551 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1562 device after it was deleted. Instead add and remove cap's from the
1563 cap db as they are created and deleted. This ensuring that a
1564 capibility is only used during the lifetime of the corresponding
1567 * cap.h, cap.c: Correct cap type - was signed32 should be
1570 * cap.c (cap_add, cap_remove): New methods for cap object that

1575 remaining in the cap data base are those that were entered first.
1576 Thse objects will be the permenant ones.
1577 * device.c (device_init_address): Remember to initialize the cap
1580 * device.c (device_create_instance_from): Explicitly add device
