326 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
328 * sim-endian.h: Don't have parameters on macro definitions which
329 are simply renaming functions, to permit use of XCONCAT2 in both
330 the macro name and the arguments in a use of such a definition.
332 2000-11-15 Jim Blandy <jimb@redhat.com>
334 * sim_calls.c: Doc fix.
335 (sim_fetch_register, sim_store_register): Call

366 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
368 * configure: Regenerated to track ../common/aclocal.m4 changes.
370 1999-05-08 Felix Lee <flee@cygnus.com>
372 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
373 * configure: Regenerated to track ../common/aclocal.m4 changes.
375 1999-04-02 Keith Seitz <keiths@cygnus.com>

383 1999-02-22 Jim Lemke <jlemke@cygnus.com>
385 * dc-complex: Force expansion on all bits of field BO.

393 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
395 Make the simulator compatible with the MPC750. It would be nicer
396 to make this a real multi-sim, but that's more work than we have
398 * emul_generic.c (emul_add_tree_options): Only require strict
399 alignment if it was explicitly requested at configuration time.
400 Don't make it the default for little-endian machines.
401 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
402 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
403 THRM2, THRM3): Plop in the MPC750 SPR registers.
404 (DABR): This is weird. This was HID5, but the PPC spec says this
405 should be DABR; why did some random processor use it for something
406 else? The HID5 entry dates back to the original checkin of the
407 simulator code in 1995, so remove it.
408 * sim_calls.c (register_names): Delete this; since the user can
409 now change GDB's list of register names dynamically, we can't
410 pretend there's a static mapping here.
411 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
412 function to get the register name. That ought to be accurate.
413 However, we're changing a compile-time dependency (using the
414 REGISTER_NAMES macro) into a link- and run-time dependency
415 (calling REGISTER_NAME, which happens to be a function call on the
418 1999-01-22 Jim Lemke <jlemke@cygnus.com>
420 * igen.c(gen_semantics_[ch]): setup/use of new option
422 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
423 ppc-instructions(the four branch insn groups): detect problematic br's.
424 psim.c(is_num - added, psim_options): Parse and init new option.
425 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
427 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
429 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

437 (event_queue_init): Copy scheduling of sim_events_poll from same.
439 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
440 poll the external environment.
442 1998-11-19 Michael Meissner <meissner@cygnus.com>
444 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
445 fractional type, so that quiet NaN's aren't treated like
448 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
450 * table.c (table_open): For cygwin hosts, we need to use the
451 return value from the read routine as the number of bytes to
452 process. This apparently is due to text-mode vs binary-mode. If
453 the mounts are done text-mode, then the size returnedby fstat()
454 may be different than the number of bytes "read" in text mode.
456 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
458 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

469 * sim_calls.c (sim_fetch_register, sim_store_register):
470 return zero when nothing to do.
472 1998-06-26 Michael Meissner <meissner@cygnus.com>
474 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
475 * configure: Regenerate.
476 * emul_{netbsd,unix}.c (toplevel): No longer try to include
477 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
479 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
481 * Makefile.in: The run target depended on a target psim$(EXEEXT),
482 but there was no such target, only plain psim. So I changed the
483 run target to depend on psim.
485 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
487 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
488 now defined in ../common/aclocal.m4, and the double definition causes
489 problems with AC_SUBST of EXEEXT.
490 * configure: Regenerate.
492 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>

891 determine the simulation speed by looking at the number of elapsed
892 ticks recorded by the event queue.
894 * psim.c (psim_write_register, psim_read_register): Force the cpu
895 to zero when it is either of `-1' or `nr_cpus'. In both cases the
896 next cpu would be zero any way.
898 * mon.c (mon_print_info): If possible, print the system cycle
899 performance. This is an indication of the number of instructions
902 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
904 * The code to allow an event queue to be updated during a signal
905 was missing. For main.c, a cntrl-c simulation termination wasn't
908 * The simulation would not correctly restart if an event requested
909 that the simulation be halted.

912 include a level vis -i2.
913 (psim_usage): Document.

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

1010 * gen-icache.c (print_icache_extraction): For a cache entry of
1011 the form <name>_is_<const> where it is a boolean field, generate
1012 the result of the expression instead of the expression its self.

1014 then generating corresponding definitions.
1016 * gen-icache.c (print_icache_struct): If there is no cache, do not
1017 output expressions in idecode.h file.

1026 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1028 * The code that put values in and extracted values from the cache
1029 was too compilicated. The cache table did not allow values to be
1030 computed from cache entries. #defines could only be used when a
1031 cache was present, remove the restriction.
1033 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1034 scratch variable is defined when a cache entry is beinf
1035 filled. Change the definition of a COMPUTE variable to be defined
1036 when the cache entry is being used.
1037 * gen-icache.c: Update.
1039 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1040 is more obvious. old_name->field_name, new_name->derived_name.
1041 * gen-icache.c: Update
1043 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1044 different types of cache code - put into cache, extract from
1045 cache, no cache - an explicit argument to print_icache_body.

1048 * gen-semantics.c (print_c_semantic): Update use.
1049 * gen-idecode.c (print_jump_insn): Update use.
1050 * gen-icache.c (print_icache_function): Update use.
1052 * igen.c (main): Change 'R' option so that it does not force the
1055 * configure.in (enable-sim-icache): Clarify description. Make
1056 #define one of the defaults regardless of the cache. Probably
1057 should revamp and add a separate option.
1059 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1061 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
