865 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
867 * sim-endian.h: Don't have parameters on macro definitions which
868 are simply renaming functions, to permit use of XCONCAT2 in both
869 the macro name and the arguments in a use of such a definition.
871 2000-11-15 Jim Blandy <jimb@redhat.com>
873 * sim_calls.c: Doc fix.
874 (sim_fetch_register, sim_store_register): Call

909 1999-05-08 Felix Lee <flee@cygnus.com>
911 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
912 * configure: Regenerated to track ../common/aclocal.m4 changes.
914 1999-04-02 Keith Seitz <keiths@cygnus.com>

920 after the specified POLL_QUIT_INTERVAL.
922 1999-02-22 Jim Lemke <jlemke@cygnus.com>
924 * dc-complex: Force expansion on all bits of field BO.

932 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
934 Make the simulator compatible with the MPC750. It would be nicer
935 to make this a real multi-sim, but that's more work than we have
937 * emul_generic.c (emul_add_tree_options): Only require strict
938 alignment if it was explicitly requested at configuration time.
939 Don't make it the default for little-endian machines.
940 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
941 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
942 THRM2, THRM3): Plop in the MPC750 SPR registers.
943 (DABR): This is weird. This was HID5, but the PPC spec says this
944 should be DABR; why did some random processor use it for something
945 else? The HID5 entry dates back to the original checkin of the
946 simulator code in 1995, so remove it.
947 * sim_calls.c (register_names): Delete this; since the user can
948 now change GDB's list of register names dynamically, we can't
949 pretend there's a static mapping here.
950 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
951 function to get the register name. That ought to be accurate.
952 However, we're changing a compile-time dependency (using the
953 REGISTER_NAMES macro) into a link- and run-time dependency
954 (calling REGISTER_NAME, which happens to be a function call on the
957 1999-01-22 Jim Lemke <jlemke@cygnus.com>

964 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

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

1013 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
1014 * configure: Regenerate.
1015 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1016 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1018 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1020 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1021 but there was no such target, only plain psim. So I changed the
1022 run target to depend on psim.
1024 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1026 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1027 now defined in ../common/aclocal.m4, and the double definition causes
1028 problems with AC_SUBST of EXEEXT.
1029 * configure: Regenerate.
1031 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>

1430 determine the simulation speed by looking at the number of elapsed
1431 ticks recorded by the event queue.
1433 * psim.c (psim_write_register, psim_read_register): Force the cpu
1434 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1435 next cpu would be zero any way.
1437 * mon.c (mon_print_info): If possible, print the system cycle
1438 performance. This is an indication of the number of instructions
1441 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1443 * The code to allow an event queue to be updated during a signal
1444 was missing. For main.c, a cntrl-c simulation termination wasn't
1447 * The simulation would not correctly restart if an event requested
1448 that the simulation be halted.
1450 * psim.c (psim_options): Add hack to -i option to optionally
1451 include a level vis -i2.
1452 (psim_usage): Document.

1471 * gen-idecode.c (print_run_until_stop_body): Call
1472 event_queue_process_events to clear possibly pending events before
1473 starting a simulation run. Re-arange main loop so that simulator
1474 is correctly restarted when an event halts the simulation.
1476 * psim.c (psim_halt): Handle an event halting the simulation.
1477 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1480 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1500 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1501 to be initialized independant of the rest of the simulation
1502 initalization. Otherwize a trace option explictly set from gdb
1503 could be overridden by hw_trace.
1505 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1507 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1508 debug.c. It could be much simpler.
1510 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1523 media. If no file image is specified, use the next one in the
1524 image property list.
1525 (hw_disk_init_address): Change the file property so that it is a
1526 string array - use the first entry for the initial file image.
1528 * tree.c (print_string_aray_property): New function - print a
1530 (print_properties): Adjust.

1545 as RA_is_0. If possible generate the result of the expression so
1546 that the compiler gets a better chance of eliminating dead
1549 * gen-icache.c (print_icache_extraction): For a cache entry of
1550 the form <name>_is_<const> where it is a boolean field, generate
1551 the result of the expression instead of the expression its self.
1552 (print_icache_body): Remove code that was looking for *_is_0 and
1553 then generating corresponding definitions.
1555 * gen-icache.c (print_icache_struct): If there is no cache, do not
1556 output expressions in idecode.h file.
1558 * gen-icache.c (print_icache_body): Output them here.
1560 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1565 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1567 * The code that put values in and extracted values from the cache
1568 was too compilicated. The cache table did not allow values to be
1569 computed from cache entries. #defines could only be used when a
1570 cache was present, remove the restriction.
1572 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1573 scratch variable is defined when a cache entry is beinf
1574 filled. Change the definition of a COMPUTE variable to be defined
1575 when the cache entry is being used.
1576 * gen-icache.c: Update.
1578 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1579 is more obvious. old_name->field_name, new_name->derived_name.
1580 * gen-icache.c: Update
1582 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1583 different types of cache code - put into cache, extract from
