856 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
858 * sim-endian.h: Don't have parameters on macro definitions which
859 are simply renaming functions, to permit use of XCONCAT2 in both
860 the macro name and the arguments in a use of such a definition.
862 2000-11-15 Jim Blandy <jimb@redhat.com>
864 * sim_calls.c: Doc fix.
865 (sim_fetch_register, sim_store_register): Call

900 1999-05-08 Felix Lee <flee@cygnus.com>
902 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
903 * configure: Regenerated to track ../common/aclocal.m4 changes.
905 1999-04-02 Keith Seitz <keiths@cygnus.com>

911 after the specified POLL_QUIT_INTERVAL.
913 1999-02-22 Jim Lemke <jlemke@cygnus.com>
915 * dc-complex: Force expansion on all bits of field BO.

923 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
925 Make the simulator compatible with the MPC750. It would be nicer
926 to make this a real multi-sim, but that's more work than we have
928 * emul_generic.c (emul_add_tree_options): Only require strict
929 alignment if it was explicitly requested at configuration time.
930 Don't make it the default for little-endian machines.
931 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
932 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
933 THRM2, THRM3): Plop in the MPC750 SPR registers.
934 (DABR): This is weird. This was HID5, but the PPC spec says this
935 should be DABR; why did some random processor use it for something
936 else? The HID5 entry dates back to the original checkin of the
937 simulator code in 1995, so remove it.
938 * sim_calls.c (register_names): Delete this; since the user can
939 now change GDB's list of register names dynamically, we can't
940 pretend there's a static mapping here.
941 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
942 function to get the register name. That ought to be accurate.
943 However, we're changing a compile-time dependency (using the
944 REGISTER_NAMES macro) into a link- and run-time dependency
945 (calling REGISTER_NAME, which happens to be a function call on the
948 1999-01-22 Jim Lemke <jlemke@cygnus.com>
950 * igen.c(gen_semantics_[ch]): setup/use of new option

954 psim.c(is_num - added, psim_options): Parse and init new option.
955 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
957 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
959 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

970 poll the external environment.
972 1998-11-19 Michael Meissner <meissner@cygnus.com>
974 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
975 fractional type, so that quiet NaN's aren't treated like
978 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
980 * table.c (table_open): For cygwin hosts, we need to use the
981 return value from the read routine as the number of bytes to
982 process. This apparently is due to text-mode vs binary-mode. If
983 the mounts are done text-mode, then the size returnedby fstat()
984 may be different than the number of bytes "read" in text mode.
986 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
988 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1004 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
1005 * configure: Regenerate.
1006 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1007 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1009 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1011 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1012 but there was no such target, only plain psim. So I changed the
1013 run target to depend on psim.
1015 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1017 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1018 now defined in ../common/aclocal.m4, and the double definition causes
1019 problems with AC_SUBST of EXEEXT.
1020 * configure: Regenerate.
1022 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>
1024 * aclocal.m4: new file for AM_EXEEXT macro

1421 determine the simulation speed by looking at the number of elapsed
1422 ticks recorded by the event queue.
1424 * psim.c (psim_write_register, psim_read_register): Force the cpu
1425 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1426 next cpu would be zero any way.
1428 * mon.c (mon_print_info): If possible, print the system cycle
1429 performance. This is an indication of the number of instructions
1432 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1434 * The code to allow an event queue to be updated during a signal
1435 was missing. For main.c, a cntrl-c simulation termination wasn't
1438 * The simulation would not correctly restart if an event requested
1439 that the simulation be halted.
1441 * psim.c (psim_options): Add hack to -i option to optionally
1442 include a level vis -i2.
1443 (psim_usage): Document.

1462 * gen-idecode.c (print_run_until_stop_body): Call
1463 event_queue_process_events to clear possibly pending events before
1464 starting a simulation run. Re-arange main loop so that simulator
1465 is correctly restarted when an event halts the simulation.
1467 * psim.c (psim_halt): Handle an event halting the simulation.
1468 * psim.c (psim_init): Adjust initial cpu - == -1 - to match

1491 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1492 to be initialized independant of the rest of the simulation
1493 initalization. Otherwize a trace option explictly set from gdb
1494 could be overridden by hw_trace.
1496 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1498 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1499 debug.c. It could be much simpler.
1501 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1517 string array - use the first entry for the initial file image.
1519 * tree.c (print_string_aray_property): New function - print a

1536 as RA_is_0. If possible generate the result of the expression so
1537 that the compiler gets a better chance of eliminating dead
1540 * gen-icache.c (print_icache_extraction): For a cache entry of
1541 the form <name>_is_<const> where it is a boolean field, generate
1542 the result of the expression instead of the expression its self.
1543 (print_icache_body): Remove code that was looking for *_is_0 and
1544 then generating corresponding definitions.
1546 * gen-icache.c (print_icache_struct): If there is no cache, do not
1547 output expressions in idecode.h file.
1549 * gen-icache.c (print_icache_body): Output them here.
1551 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1556 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1558 * The code that put values in and extracted values from the cache
1559 was too compilicated. The cache table did not allow values to be
1560 computed from cache entries. #defines could only be used when a
1561 cache was present, remove the restriction.
1563 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1564 scratch variable is defined when a cache entry is beinf
1565 filled. Change the definition of a COMPUTE variable to be defined
1566 when the cache entry is being used.
1567 * gen-icache.c: Update.
1569 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1570 is more obvious. old_name->field_name, new_name->derived_name.
1571 * gen-icache.c: Update
1573 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1574 different types of cache code - put into cache, extract from
1575 cache, no cache - an explicit argument to print_icache_body.
