351 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
353 * sim-endian.h: Don't have parameters on macro definitions which
354 are simply renaming functions, to permit use of XCONCAT2 in both
355 the macro name and the arguments in a use of such a definition.
357 2000-11-15 Jim Blandy <jimb@redhat.com>
359 * sim_calls.c: Doc fix.
360 (sim_fetch_register, sim_store_register): Call

395 1999-05-08 Felix Lee <flee@cygnus.com>
397 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
398 * configure: Regenerated to track ../common/aclocal.m4 changes.
400 1999-04-02 Keith Seitz <keiths@cygnus.com>
402 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak

406 after the specified POLL_QUIT_INTERVAL.
408 1999-02-22 Jim Lemke <jlemke@cygnus.com>
410 * dc-complex: Force expansion on all bits of field BO.
411 Previously, the least-significant (prediction) bit was ignored.
412 * ppc-instructions (conditional branches): Implement mpc860c0 option.

418 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
420 Make the simulator compatible with the MPC750. It would be nicer
421 to make this a real multi-sim, but that's more work than we have
423 * emul_generic.c (emul_add_tree_options): Only require strict
424 alignment if it was explicitly requested at configuration time.
425 Don't make it the default for little-endian machines.
426 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
427 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
428 THRM2, THRM3): Plop in the MPC750 SPR registers.
429 (DABR): This is weird. This was HID5, but the PPC spec says this
430 should be DABR; why did some random processor use it for something
431 else? The HID5 entry dates back to the original checkin of the
432 simulator code in 1995, so remove it.
433 * sim_calls.c (register_names): Delete this; since the user can
434 now change GDB's list of register names dynamically, we can't
435 pretend there's a static mapping here.
436 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
437 function to get the register name. That ought to be accurate.
438 However, we're changing a compile-time dependency (using the
439 REGISTER_NAMES macro) into a link- and run-time dependency
440 (calling REGISTER_NAME, which happens to be a function call on the
443 1999-01-22 Jim Lemke <jlemke@cygnus.com>
445 * igen.c(gen_semantics_[ch]): setup/use of new option
447 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
448 ppc-instructions(the four branch insn groups): detect problematic br's.
449 psim.c(is_num - added, psim_options): Parse and init new option.
450 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
452 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
454 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

464 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
465 poll the external environment.
467 1998-11-19 Michael Meissner <meissner@cygnus.com>
469 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
470 fractional type, so that quiet NaN's aren't treated like
473 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
475 * table.c (table_open): For cygwin hosts, we need to use the
476 return value from the read routine as the number of bytes to
477 process. This apparently is due to text-mode vs binary-mode. If
478 the mounts are done text-mode, then the size returnedby fstat()
479 may be different than the number of bytes "read" in text mode.
481 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
483 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

490 * emul_{netbsd,unix}.c: Update copyright year.
492 Mon Jun 29 10:57:36 1998 Michael Snyder <msnyder@cleaver.cygnus.com>
494 * sim_calls.c (sim_fetch_register, sim_store_register):
495 return zero when nothing to do.
497 1998-06-26 Michael Meissner <meissner@cygnus.com>
499 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
500 * configure: Regenerate.
501 * emul_{netbsd,unix}.c (toplevel): No longer try to include
502 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
504 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
506 * Makefile.in: The run target depended on a target psim$(EXEEXT),
507 but there was no such target, only plain psim. So I changed the
508 run target to depend on psim.
510 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
512 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are

916 determine the simulation speed by looking at the number of elapsed
917 ticks recorded by the event queue.
919 * psim.c (psim_write_register, psim_read_register): Force the cpu
920 to zero when it is either of `-1' or `nr_cpus'. In both cases the
921 next cpu would be zero any way.
923 * mon.c (mon_print_info): If possible, print the system cycle
924 performance. This is an indication of the number of instructions
927 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
929 * The code to allow an event queue to be updated during a signal
930 was missing. For main.c, a cntrl-c simulation termination wasn't

934 that the simulation be halted.
936 * psim.c (psim_options): Add hack to -i option to optionally
937 include a level vis -i2.
938 (psim_usage): Document.

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

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

974 here. Update to new format.

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

1010 image property list.
1011 (hw_disk_init_address): Change the file property so that it is a
1012 string array - use the first entry for the initial file image.
1014 * tree.c (print_string_aray_property): New function - print a

1035 * gen-icache.c (print_icache_extraction): For a cache entry of
1036 the form <name>_is_<const> where it is a boolean field, generate
1037 the result of the expression instead of the expression its self.

1042 output expressions in idecode.h file.

1051 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1053 * The code that put values in and extracted values from the cache
1054 was too compilicated. The cache table did not allow values to be
1055 computed from cache entries. #defines could only be used when a
1056 cache was present, remove the restriction.
1058 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1059 scratch variable is defined when a cache entry is beinf
1060 filled. Change the definition of a COMPUTE variable to be defined
1061 when the cache entry is being used.
1062 * gen-icache.c: Update.
1064 * ld-cache.h, ld-cache.c: Change field names so that their meaning

2618 * Makefile.in (filter.o): Adjust
2619 * configure.in: Adjust filter flag so that default includes 32bit
