870 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
872 * sim-endian.h: Don't have parameters on macro definitions which
873 are simply renaming functions, to permit use of XCONCAT2 in both
874 the macro name and the arguments in a use of such a definition.
876 2000-11-15 Jim Blandy <jimb@redhat.com>
878 * sim_calls.c: Doc fix.
879 (sim_fetch_register, sim_store_register): Call

914 1999-05-08 Felix Lee <flee@cygnus.com>
916 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
917 * configure: Regenerated to track ../common/aclocal.m4 changes.
919 1999-04-02 Keith Seitz <keiths@cygnus.com>

925 after the specified POLL_QUIT_INTERVAL.
927 1999-02-22 Jim Lemke <jlemke@cygnus.com>
929 * dc-complex: Force expansion on all bits of field BO.

937 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
939 Make the simulator compatible with the MPC750. It would be nicer
940 to make this a real multi-sim, but that's more work than we have
942 * emul_generic.c (emul_add_tree_options): Only require strict
943 alignment if it was explicitly requested at configuration time.
944 Don't make it the default for little-endian machines.
945 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
946 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
947 THRM2, THRM3): Plop in the MPC750 SPR registers.
948 (DABR): This is weird. This was HID5, but the PPC spec says this
949 should be DABR; why did some random processor use it for something
950 else? The HID5 entry dates back to the original checkin of the
951 simulator code in 1995, so remove it.
952 * sim_calls.c (register_names): Delete this; since the user can
953 now change GDB's list of register names dynamically, we can't
954 pretend there's a static mapping here.
955 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
956 function to get the register name. That ought to be accurate.
957 However, we're changing a compile-time dependency (using the
958 REGISTER_NAMES macro) into a link- and run-time dependency
959 (calling REGISTER_NAME, which happens to be a function call on the
962 1999-01-22 Jim Lemke <jlemke@cygnus.com>
964 * igen.c(gen_semantics_[ch]): setup/use of new option

968 psim.c(is_num - added, psim_options): Parse and init new option.
969 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
971 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
973 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

986 1998-11-19 Michael Meissner <meissner@cygnus.com>
988 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
989 fractional type, so that quiet NaN's aren't treated like
992 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
994 * table.c (table_open): For cygwin hosts, we need to use the
995 return value from the read routine as the number of bytes to
996 process. This apparently is due to text-mode vs binary-mode. If
997 the mounts are done text-mode, then the size returnedby fstat()
998 may be different than the number of bytes "read" in text mode.
1000 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1002 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1018 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
1019 * configure: Regenerate.
1020 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1021 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1023 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1025 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1026 but there was no such target, only plain psim. So I changed the
1027 run target to depend on psim.
1029 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1031 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1032 now defined in ../common/aclocal.m4, and the double definition causes
1033 problems with AC_SUBST of EXEEXT.
1034 * configure: Regenerate.
1036 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>
1038 * aclocal.m4: new file for AM_EXEEXT macro

1435 determine the simulation speed by looking at the number of elapsed
1436 ticks recorded by the event queue.
1438 * psim.c (psim_write_register, psim_read_register): Force the cpu
1439 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1440 next cpu would be zero any way.
1442 * mon.c (mon_print_info): If possible, print the system cycle
1443 performance. This is an indication of the number of instructions
1446 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1448 * The code to allow an event queue to be updated during a signal
1449 was missing. For main.c, a cntrl-c simulation termination wasn't
1452 * The simulation would not correctly restart if an event requested
1453 that the simulation be halted.
1455 * psim.c (psim_options): Add hack to -i option to optionally
1456 include a level vis -i2.
1457 (psim_usage): Document.

1476 * gen-idecode.c (print_run_until_stop_body): Call
1477 event_queue_process_events to clear possibly pending events before
1478 starting a simulation run. Re-arange main loop so that simulator
1479 is correctly restarted when an event halts the simulation.
1481 * psim.c (psim_halt): Handle an event halting the simulation.
1482 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1485 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1505 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1506 to be initialized independant of the rest of the simulation
1507 initalization. Otherwize a trace option explictly set from gdb
1508 could be overridden by hw_trace.
1510 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1512 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1513 debug.c. It could be much simpler.
1515 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1517 * Some devices support removable media. Add hooks to the disk

1528 media. If no file image is specified, use the next one in the
1529 image property list.
1530 (hw_disk_init_address): Change the file property so that it is a
1531 string array - use the first entry for the initial file image.
1533 * tree.c (print_string_aray_property): New function - print a
1535 (print_properties): Adjust.

1550 as RA_is_0. If possible generate the result of the expression so
1551 that the compiler gets a better chance of eliminating dead
1554 * gen-icache.c (print_icache_extraction): For a cache entry of
1555 the form <name>_is_<const> where it is a boolean field, generate
1556 the result of the expression instead of the expression its self.
1557 (print_icache_body): Remove code that was looking for *_is_0 and
1558 then generating corresponding definitions.
1560 * gen-icache.c (print_icache_struct): If there is no cache, do not
1561 output expressions in idecode.h file.
1563 * gen-icache.c (print_icache_body): Output them here.
1565 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1568 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
1570 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1572 * The code that put values in and extracted values from the cache
1573 was too compilicated. The cache table did not allow values to be
1574 computed from cache entries. #defines could only be used when a
1575 cache was present, remove the restriction.
1577 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1578 scratch variable is defined when a cache entry is beinf
1579 filled. Change the definition of a COMPUTE variable to be defined
1580 when the cache entry is being used.
1581 * gen-icache.c: Update.
1583 * ld-cache.h, ld-cache.c: Change field names so that their meaning
