339 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
341 * sim-endian.h: Don't have parameters on macro definitions which
342 are simply renaming functions, to permit use of XCONCAT2 in both
343 the macro name and the arguments in a use of such a definition.
345 2000-11-15 Jim Blandy <jimb@redhat.com>
347 * sim_calls.c: Doc fix.
348 (sim_fetch_register, sim_store_register): Call

379 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
381 * configure: Regenerated to track ../common/aclocal.m4 changes.
383 1999-05-08 Felix Lee <flee@cygnus.com>
385 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
386 * configure: Regenerated to track ../common/aclocal.m4 changes.
388 1999-04-02 Keith Seitz <keiths@cygnus.com>
390 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak

394 after the specified POLL_QUIT_INTERVAL.
396 1999-02-22 Jim Lemke <jlemke@cygnus.com>
398 * dc-complex: Force expansion on all bits of field BO.
399 Previously, the least-significant (prediction) bit was ignored.
400 * ppc-instructions (conditional branches): Implement mpc860c0 option.
401 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
402 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

406 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
408 Make the simulator compatible with the MPC750. It would be nicer
409 to make this a real multi-sim, but that's more work than we have
411 * emul_generic.c (emul_add_tree_options): Only require strict
412 alignment if it was explicitly requested at configuration time.
413 Don't make it the default for little-endian machines.
414 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
415 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
416 THRM2, THRM3): Plop in the MPC750 SPR registers.
417 (DABR): This is weird. This was HID5, but the PPC spec says this
418 should be DABR; why did some random processor use it for something
419 else? The HID5 entry dates back to the original checkin of the
420 simulator code in 1995, so remove it.
421 * sim_calls.c (register_names): Delete this; since the user can
422 now change GDB's list of register names dynamically, we can't
423 pretend there's a static mapping here.
424 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
425 function to get the register name. That ought to be accurate.
426 However, we're changing a compile-time dependency (using the
427 REGISTER_NAMES macro) into a link- and run-time dependency
428 (calling REGISTER_NAME, which happens to be a function call on the
431 1999-01-22 Jim Lemke <jlemke@cygnus.com>
433 * igen.c(gen_semantics_[ch]): setup/use of new option
435 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
436 ppc-instructions(the four branch insn groups): detect problematic br's.
437 psim.c(is_num - added, psim_options): Parse and init new option.
438 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
440 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
442 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

450 (event_queue_init): Copy scheduling of sim_events_poll from same.
452 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
453 poll the external environment.
455 1998-11-19 Michael Meissner <meissner@cygnus.com>
457 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
458 fractional type, so that quiet NaN's aren't treated like
461 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
463 * table.c (table_open): For cygwin hosts, we need to use the
464 return value from the read routine as the number of bytes to
465 process. This apparently is due to text-mode vs binary-mode. If
466 the mounts are done text-mode, then the size returnedby fstat()
467 may be different than the number of bytes "read" in text mode.
469 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
471 * emul_netbsd.c (do_open): fix order-of-evaluation problem.
476 1998-09-03 Michael Meissner <meissner@cygnus.com>
478 * emul_{netbsd,unix}.c: Update copyright year.
480 Mon Jun 29 10:57:36 1998 Michael Snyder <msnyder@cleaver.cygnus.com>
482 * sim_calls.c (sim_fetch_register, sim_store_register):
483 return zero when nothing to do.
485 1998-06-26 Michael Meissner <meissner@cygnus.com>
487 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
488 * configure: Regenerate.
489 * emul_{netbsd,unix}.c (toplevel): No longer try to include
490 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
492 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
494 * Makefile.in: The run target depended on a target psim$(EXEEXT),
495 but there was no such target, only plain psim. So I changed the
496 run target to depend on psim.
498 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
500 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
501 now defined in ../common/aclocal.m4, and the double definition causes
502 problems with AC_SUBST of EXEEXT.
503 * configure: Regenerate.
505 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>
507 * aclocal.m4: new file for AM_EXEEXT macro
508 * configure.in: call AM_EXEEXT
509 * configure: regenerate with autoconf 2.12.1.

904 determine the simulation speed by looking at the number of elapsed
905 ticks recorded by the event queue.
907 * psim.c (psim_write_register, psim_read_register): Force the cpu
908 to zero when it is either of `-1' or `nr_cpus'. In both cases the
909 next cpu would be zero any way.
911 * mon.c (mon_print_info): If possible, print the system cycle
912 performance. This is an indication of the number of instructions
915 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
917 * The code to allow an event queue to be updated during a signal

922 that the simulation be halted.
924 * psim.c (psim_options): Add hack to -i option to optionally
925 include a level vis -i2.
926 (psim_usage): Document.

940 (event_queue_init): Start the event queue out with processing
942 (event_queue_tick): Check that processing isn't still being
945 * gen-idecode.c (print_run_until_stop_body): Call
946 event_queue_process_events to clear possibly pending events before
947 starting a simulation run. Re-arange main loop so that simulator
948 is correctly restarted when an event halts the simulation.

951 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
954 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

962 here. Update to new format.

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

1000 string array - use the first entry for the initial file image.
1002 * tree.c (print_string_aray_property): New function - print a
1004 (print_properties): Adjust.

1019 as RA_is_0. If possible generate the result of the expression so
1020 that the compiler gets a better chance of eliminating dead
1023 * gen-icache.c (print_icache_extraction): For a cache entry of
1024 the form <name>_is_<const> where it is a boolean field, generate
1025 the result of the expression instead of the expression its self.

1039 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1041 * The code that put values in and extracted values from the cache
1042 was too compilicated. The cache table did not allow values to be
1043 computed from cache entries. #defines could only be used when a
1044 cache was present, remove the restriction.
1046 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1047 scratch variable is defined when a cache entry is beinf
1048 filled. Change the definition of a COMPUTE variable to be defined
1049 when the cache entry is being used.
1050 * gen-icache.c: Update.
1052 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1053 is more obvious. old_name->field_name, new_name->derived_name.
1054 * gen-icache.c: Update
1056 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1057 different types of cache code - put into cache, extract from
1058 cache, no cache - an explicit argument to print_icache_body.

1061 * gen-semantics.c (print_c_semantic): Update use.
1062 * gen-idecode.c (print_jump_insn): Update use.

2606 * Makefile.in (filter.o): Adjust
2607 * configure.in: Adjust filter flag so that default includes 32bit
