839 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
841 * sim-endian.h: Don't have parameters on macro definitions which
842 are simply renaming functions, to permit use of XCONCAT2 in both
843 the macro name and the arguments in a use of such a definition.
845 2000-11-15 Jim Blandy <jimb@redhat.com>
847 * sim_calls.c: Doc fix.
848 (sim_fetch_register, sim_store_register): Call

883 1999-05-08 Felix Lee <flee@cygnus.com>
885 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
886 * configure: Regenerated to track ../common/aclocal.m4 changes.
888 1999-04-02 Keith Seitz <keiths@cygnus.com>

894 after the specified POLL_QUIT_INTERVAL.
896 1999-02-22 Jim Lemke <jlemke@cygnus.com>
898 * dc-complex: Force expansion on all bits of field BO.

906 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
908 Make the simulator compatible with the MPC750. It would be nicer
909 to make this a real multi-sim, but that's more work than we have
911 * emul_generic.c (emul_add_tree_options): Only require strict
912 alignment if it was explicitly requested at configuration time.
913 Don't make it the default for little-endian machines.
914 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
915 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
916 THRM2, THRM3): Plop in the MPC750 SPR registers.
917 (DABR): This is weird. This was HID5, but the PPC spec says this
918 should be DABR; why did some random processor use it for something
919 else? The HID5 entry dates back to the original checkin of the
920 simulator code in 1995, so remove it.
921 * sim_calls.c (register_names): Delete this; since the user can
922 now change GDB's list of register names dynamically, we can't
923 pretend there's a static mapping here.
924 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
925 function to get the register name. That ought to be accurate.
926 However, we're changing a compile-time dependency (using the
927 REGISTER_NAMES macro) into a link- and run-time dependency
928 (calling REGISTER_NAME, which happens to be a function call on the
931 1999-01-22 Jim Lemke <jlemke@cygnus.com>
933 * igen.c(gen_semantics_[ch]): setup/use of new option

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

953 poll the external environment.
955 1998-11-19 Michael Meissner <meissner@cygnus.com>
957 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
958 fractional type, so that quiet NaN's aren't treated like
961 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
963 * table.c (table_open): For cygwin hosts, we need to use the
964 return value from the read routine as the number of bytes to
965 process. This apparently is due to text-mode vs binary-mode. If
966 the mounts are done text-mode, then the size returnedby fstat()
967 may be different than the number of bytes "read" in text mode.
969 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
971 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

988 * configure: Regenerate.
989 * emul_{netbsd,unix}.c (toplevel): No longer try to include
990 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
992 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
994 * Makefile.in: The run target depended on a target psim$(EXEEXT),
995 but there was no such target, only plain psim. So I changed the
996 run target to depend on psim.
998 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1000 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1001 now defined in ../common/aclocal.m4, and the double definition causes
1002 problems with AC_SUBST of EXEEXT.
1003 * configure: Regenerate.
1005 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>

1404 determine the simulation speed by looking at the number of elapsed
1405 ticks recorded by the event queue.
1407 * psim.c (psim_write_register, psim_read_register): Force the cpu
1408 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1409 next cpu would be zero any way.
1411 * mon.c (mon_print_info): If possible, print the system cycle
1412 performance. This is an indication of the number of instructions
1415 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1417 * The code to allow an event queue to be updated during a signal
1418 was missing. For main.c, a cntrl-c simulation termination wasn't
1421 * The simulation would not correctly restart if an event requested
1422 that the simulation be halted.
1424 * psim.c (psim_options): Add hack to -i option to optionally
1425 include a level vis -i2.
1426 (psim_usage): Document.

1442 (event_queue_tick): Check that processing isn't still being
1445 * gen-idecode.c (print_run_until_stop_body): Call
1446 event_queue_process_events to clear possibly pending events before
1447 starting a simulation run. Re-arange main loop so that simulator
1448 is correctly restarted when an event halts the simulation.

1474 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1475 to be initialized independant of the rest of the simulation
1476 initalization. Otherwize a trace option explictly set from gdb
1477 could be overridden by hw_trace.
1479 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1481 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1482 debug.c. It could be much simpler.
1484 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1500 string array - use the first entry for the initial file image.
1502 * tree.c (print_string_aray_property): New function - print a

1523 * gen-icache.c (print_icache_extraction): For a cache entry of
1524 the form <name>_is_<const> where it is a boolean field, generate
1525 the result of the expression instead of the expression its self.
1526 (print_icache_body): Remove code that was looking for *_is_0 and
1527 then generating corresponding definitions.
1529 * gen-icache.c (print_icache_struct): If there is no cache, do not
1530 output expressions in idecode.h file.
1532 * gen-icache.c (print_icache_body): Output them here.
1534 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1539 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1541 * The code that put values in and extracted values from the cache
1542 was too compilicated. The cache table did not allow values to be
1543 computed from cache entries. #defines could only be used when a
1544 cache was present, remove the restriction.
1546 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1547 scratch variable is defined when a cache entry is beinf
1548 filled. Change the definition of a COMPUTE variable to be defined
1549 when the cache entry is being used.
1550 * gen-icache.c: Update.
1552 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1553 is more obvious. old_name->field_name, new_name->derived_name.
1554 * gen-icache.c: Update
1556 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1557 different types of cache code - put into cache, extract from
1558 cache, no cache - an explicit argument to print_icache_body.
1559 * gen-icache.c (print_icache_extraction): Ditto.
1561 * gen-semantics.c (print_c_semantic): Update use.
1562 * gen-idecode.c (print_jump_insn): Update use.
1563 * gen-icache.c (print_icache_function): Update use.
1565 * igen.c (main): Change 'R' option so that it does not force the
1568 * configure.in (enable-sim-icache): Clarify description. Make
1569 #define one of the defaults regardless of the cache. Probably
1570 should revamp and add a separate option.
1572 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1574 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
