844 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
846 * sim-endian.h: Don't have parameters on macro definitions which
847 are simply renaming functions, to permit use of XCONCAT2 in both
848 the macro name and the arguments in a use of such a definition.
850 2000-11-15 Jim Blandy <jimb@redhat.com>
852 * sim_calls.c: Doc fix.
853 (sim_fetch_register, sim_store_register): Call

888 1999-05-08 Felix Lee <flee@cygnus.com>
890 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
891 * configure: Regenerated to track ../common/aclocal.m4 changes.
893 1999-04-02 Keith Seitz <keiths@cygnus.com>

899 after the specified POLL_QUIT_INTERVAL.
901 1999-02-22 Jim Lemke <jlemke@cygnus.com>
903 * dc-complex: Force expansion on all bits of field BO.

911 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
913 Make the simulator compatible with the MPC750. It would be nicer
914 to make this a real multi-sim, but that's more work than we have
916 * emul_generic.c (emul_add_tree_options): Only require strict
917 alignment if it was explicitly requested at configuration time.
918 Don't make it the default for little-endian machines.
919 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
920 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
921 THRM2, THRM3): Plop in the MPC750 SPR registers.
922 (DABR): This is weird. This was HID5, but the PPC spec says this
923 should be DABR; why did some random processor use it for something
924 else? The HID5 entry dates back to the original checkin of the
925 simulator code in 1995, so remove it.
926 * sim_calls.c (register_names): Delete this; since the user can
927 now change GDB's list of register names dynamically, we can't
928 pretend there's a static mapping here.
929 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
930 function to get the register name. That ought to be accurate.
931 However, we're changing a compile-time dependency (using the
932 REGISTER_NAMES macro) into a link- and run-time dependency
933 (calling REGISTER_NAME, which happens to be a function call on the
936 1999-01-22 Jim Lemke <jlemke@cygnus.com>
938 * igen.c(gen_semantics_[ch]): setup/use of new option

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

960 1998-11-19 Michael Meissner <meissner@cygnus.com>
962 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
963 fractional type, so that quiet NaN's aren't treated like
966 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
968 * table.c (table_open): For cygwin hosts, we need to use the
969 return value from the read routine as the number of bytes to
970 process. This apparently is due to text-mode vs binary-mode. If
971 the mounts are done text-mode, then the size returnedby fstat()
972 may be different than the number of bytes "read" in text mode.
974 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
976 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

993 * configure: Regenerate.
994 * emul_{netbsd,unix}.c (toplevel): No longer try to include
995 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
997 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
999 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1000 but there was no such target, only plain psim. So I changed the
1001 run target to depend on psim.
1003 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1005 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1006 now defined in ../common/aclocal.m4, and the double definition causes
1007 problems with AC_SUBST of EXEEXT.
1008 * configure: Regenerate.
1010 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>

1409 determine the simulation speed by looking at the number of elapsed
1410 ticks recorded by the event queue.
1412 * psim.c (psim_write_register, psim_read_register): Force the cpu
1413 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1414 next cpu would be zero any way.
1416 * mon.c (mon_print_info): If possible, print the system cycle
1417 performance. This is an indication of the number of instructions
1420 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1422 * The code to allow an event queue to be updated during a signal
1423 was missing. For main.c, a cntrl-c simulation termination wasn't
1426 * The simulation would not correctly restart if an event requested
1427 that the simulation be halted.
1429 * psim.c (psim_options): Add hack to -i option to optionally
1430 include a level vis -i2.
1431 (psim_usage): Document.

1447 (event_queue_tick): Check that processing isn't still being
1450 * gen-idecode.c (print_run_until_stop_body): Call
1451 event_queue_process_events to clear possibly pending events before
1452 starting a simulation run. Re-arange main loop so that simulator
1453 is correctly restarted when an event halts the simulation.
1455 * psim.c (psim_halt): Handle an event halting the simulation.
1456 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1459 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1477 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1479 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1480 to be initialized independant of the rest of the simulation
1481 initalization. Otherwize a trace option explictly set from gdb
1482 could be overridden by hw_trace.
1484 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1486 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1487 debug.c. It could be much simpler.
1489 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1505 string array - use the first entry for the initial file image.
1507 * tree.c (print_string_aray_property): New function - print a
1509 (print_properties): Adjust.

1524 as RA_is_0. If possible generate the result of the expression so
1525 that the compiler gets a better chance of eliminating dead
1528 * gen-icache.c (print_icache_extraction): For a cache entry of
1529 the form <name>_is_<const> where it is a boolean field, generate
1530 the result of the expression instead of the expression its self.
1531 (print_icache_body): Remove code that was looking for *_is_0 and
1532 then generating corresponding definitions.
1534 * gen-icache.c (print_icache_struct): If there is no cache, do not
1535 output expressions in idecode.h file.
1537 * gen-icache.c (print_icache_body): Output them here.
1539 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1544 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1546 * The code that put values in and extracted values from the cache
1547 was too compilicated. The cache table did not allow values to be
1548 computed from cache entries. #defines could only be used when a
1549 cache was present, remove the restriction.
1551 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1552 scratch variable is defined when a cache entry is beinf
1553 filled. Change the definition of a COMPUTE variable to be defined
1554 when the cache entry is being used.
1555 * gen-icache.c: Update.
1557 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1558 is more obvious. old_name->field_name, new_name->derived_name.
1559 * gen-icache.c: Update
1561 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1562 different types of cache code - put into cache, extract from
1563 cache, no cache - an explicit argument to print_icache_body.
1564 * gen-icache.c (print_icache_extraction): Ditto.
1566 * gen-semantics.c (print_c_semantic): Update use.
1567 * gen-idecode.c (print_jump_insn): Update use.
1568 * gen-icache.c (print_icache_function): Update use.
1570 * igen.c (main): Change 'R' option so that it does not force the
1573 * configure.in (enable-sim-icache): Clarify description. Make
1574 #define one of the defaults regardless of the cache. Probably
1575 should revamp and add a separate option.
1577 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1579 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
