354 open syscall to the numbers supported by the host.
356 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
358 * sim-endian.h: Don't have parameters on macro definitions which
359 are simply renaming functions, to permit use of XCONCAT2 in both
360 the macro name and the arguments in a use of such a definition.
362 2000-11-15 Jim Blandy <jimb@redhat.com>
364 * sim_calls.c: Doc fix.
365 (sim_fetch_register, sim_store_register): Call

394 the exponent when denormalizing.
396 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
398 * configure: Regenerated to track ../common/aclocal.m4 changes.
400 1999-05-08 Felix Lee <flee@cygnus.com>
402 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
403 * configure: Regenerated to track ../common/aclocal.m4 changes.
405 1999-04-02 Keith Seitz <keiths@cygnus.com>
407 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak

410 (sim_io_poll_quit): Only call the poll_quit callback
411 after the specified POLL_QUIT_INTERVAL.
413 1999-02-22 Jim Lemke <jlemke@cygnus.com>
415 * dc-complex: Force expansion on all bits of field BO.
416 Previously, the least-significant (prediction) bit was ignored.
417 * ppc-instructions (conditional branches): Implement mpc860c0 option.
418 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
419 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

421 * interrupts.c (program_interrupt): Added handling for above interrupt.
423 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
425 Make the simulator compatible with the MPC750. It would be nicer
426 to make this a real multi-sim, but that's more work than we have
428 * emul_generic.c (emul_add_tree_options): Only require strict
429 alignment if it was explicitly requested at configuration time.
430 Don't make it the default for little-endian machines.
431 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
432 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
433 THRM2, THRM3): Plop in the MPC750 SPR registers.
434 (DABR): This is weird. This was HID5, but the PPC spec says this
435 should be DABR; why did some random processor use it for something
436 else? The HID5 entry dates back to the original checkin of the
437 simulator code in 1995, so remove it.
438 * sim_calls.c (register_names): Delete this; since the user can
439 now change GDB's list of register names dynamically, we can't
440 pretend there's a static mapping here.
441 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
442 function to get the register name. That ought to be accurate.
443 However, we're changing a compile-time dependency (using the
444 REGISTER_NAMES macro) into a link- and run-time dependency
445 (calling REGISTER_NAME, which happens to be a function call on the
448 1999-01-22 Jim Lemke <jlemke@cygnus.com>
450 * igen.c(gen_semantics_[ch]): setup/use of new option
452 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
453 ppc-instructions(the four branch insn groups): detect problematic br's.
454 psim.c(is_num - added, psim_options): Parse and init new option.
455 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
457 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
459 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

469 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
470 poll the external environment.
472 1998-11-19 Michael Meissner <meissner@cygnus.com>
474 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
475 fractional type, so that quiet NaN's aren't treated like
478 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
480 * table.c (table_open): For cygwin hosts, we need to use the
481 return value from the read routine as the number of bytes to
482 process. This apparently is due to text-mode vs binary-mode. If
483 the mounts are done text-mode, then the size returnedby fstat()
484 may be different than the number of bytes "read" in text mode.
486 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
488 * emul_netbsd.c (do_open): fix order-of-evaluation problem.
493 1998-09-03 Michael Meissner <meissner@cygnus.com>
495 * emul_{netbsd,unix}.c: Update copyright year.
497 Mon Jun 29 10:57:36 1998 Michael Snyder <msnyder@cleaver.cygnus.com>
499 * sim_calls.c (sim_fetch_register, sim_store_register):
500 return zero when nothing to do.
502 1998-06-26 Michael Meissner <meissner@cygnus.com>
504 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
505 * configure: Regenerate.
506 * emul_{netbsd,unix}.c (toplevel): No longer try to include
507 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
509 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
511 * Makefile.in: The run target depended on a target psim$(EXEEXT),
512 but there was no such target, only plain psim. So I changed the
513 run target to depend on psim.

517 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are

921 determine the simulation speed by looking at the number of elapsed
922 ticks recorded by the event queue.
924 * psim.c (psim_write_register, psim_read_register): Force the cpu
925 to zero when it is either of `-1' or `nr_cpus'. In both cases the
926 next cpu would be zero any way.
928 * mon.c (mon_print_info): If possible, print the system cycle
929 performance. This is an indication of the number of instructions
932 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
934 * The code to allow an event queue to be updated during a signal
935 was missing. For main.c, a cntrl-c simulation termination wasn't
938 * The simulation would not correctly restart if an event requested
939 that the simulation be halted.
941 * psim.c (psim_options): Add hack to -i option to optionally
942 include a level vis -i2.
943 (psim_usage): Document.

957 (event_queue_init): Start the event queue out with processing
959 (event_queue_tick): Check that processing isn't still being
962 * gen-idecode.c (print_run_until_stop_body): Call
963 event_queue_process_events to clear possibly pending events before
964 starting a simulation run. Re-arange main loop so that simulator
965 is correctly restarted when an event halts the simulation.
967 * psim.c (psim_halt): Handle an event halting the simulation.
968 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
971 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

979 here. Update to new format.

991 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
992 to be initialized independant of the rest of the simulation
993 initalization. Otherwize a trace option explictly set from gdb
994 could be overridden by hw_trace.
996 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
998 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
999 debug.c. It could be much simpler.
1001 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1003 * Some devices support removable media. Add hooks to the disk

1014 media. If no file image is specified, use the next one in the
1015 image property list.
1016 (hw_disk_init_address): Change the file property so that it is a
1017 string array - use the first entry for the initial file image.
1019 * tree.c (print_string_aray_property): New function - print a
1021 (print_properties): Adjust.

1036 as RA_is_0. If possible generate the result of the expression so
1037 that the compiler gets a better chance of eliminating dead
1040 * gen-icache.c (print_icache_extraction): For a cache entry of
1041 the form <name>_is_<const> where it is a boolean field, generate
1042 the result of the expression instead of the expression its self.
1043 (print_icache_body): Remove code that was looking for *_is_0 and
1044 then generating corresponding definitions.
1046 * gen-icache.c (print_icache_struct): If there is no cache, do not
1047 output expressions in idecode.h file.
1049 * gen-icache.c (print_icache_body): Output them here.
1051 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1054 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
1056 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1058 * The code that put values in and extracted values from the cache
1059 was too compilicated. The cache table did not allow values to be
1060 computed from cache entries. #defines could only be used when a
1061 cache was present, remove the restriction.
1063 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1064 scratch variable is defined when a cache entry is beinf
1065 filled. Change the definition of a COMPUTE variable to be defined
1066 when the cache entry is being used.

2623 * Makefile.in (filter.o): Adjust
2624 * configure.in: Adjust filter flag so that default includes 32bit
