334 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
336 * sim-endian.h: Don't have parameters on macro definitions which
337 are simply renaming functions, to permit use of XCONCAT2 in both
338 the macro name and the arguments in a use of such a definition.
340 2000-11-15 Jim Blandy <jimb@redhat.com>
342 * sim_calls.c: Doc fix.
343 (sim_fetch_register, sim_store_register): Call

378 1999-05-08 Felix Lee <flee@cygnus.com>
380 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
381 * configure: Regenerated to track ../common/aclocal.m4 changes.
383 1999-04-02 Keith Seitz <keiths@cygnus.com>

391 1999-02-22 Jim Lemke <jlemke@cygnus.com>
393 * dc-complex: Force expansion on all bits of field BO.

401 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
403 Make the simulator compatible with the MPC750. It would be nicer
404 to make this a real multi-sim, but that's more work than we have
406 * emul_generic.c (emul_add_tree_options): Only require strict
407 alignment if it was explicitly requested at configuration time.
408 Don't make it the default for little-endian machines.
409 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
410 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
411 THRM2, THRM3): Plop in the MPC750 SPR registers.
412 (DABR): This is weird. This was HID5, but the PPC spec says this
413 should be DABR; why did some random processor use it for something
414 else? The HID5 entry dates back to the original checkin of the
415 simulator code in 1995, so remove it.
416 * sim_calls.c (register_names): Delete this; since the user can
417 now change GDB's list of register names dynamically, we can't
418 pretend there's a static mapping here.
419 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
420 function to get the register name. That ought to be accurate.
421 However, we're changing a compile-time dependency (using the
422 REGISTER_NAMES macro) into a link- and run-time dependency
423 (calling REGISTER_NAME, which happens to be a function call on the
426 1999-01-22 Jim Lemke <jlemke@cygnus.com>
428 * igen.c(gen_semantics_[ch]): setup/use of new option
430 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
431 ppc-instructions(the four branch insn groups): detect problematic br's.
432 psim.c(is_num - added, psim_options): Parse and init new option.
433 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
435 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
437 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

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

477 * sim_calls.c (sim_fetch_register, sim_store_register):
478 return zero when nothing to do.
480 1998-06-26 Michael Meissner <meissner@cygnus.com>
482 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
483 * configure: Regenerate.
484 * emul_{netbsd,unix}.c (toplevel): No longer try to include
485 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
487 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
489 * Makefile.in: The run target depended on a target psim$(EXEEXT),
490 but there was no such target, only plain psim. So I changed the
491 run target to depend on psim.
493 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
495 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
496 now defined in ../common/aclocal.m4, and the double definition causes
497 problems with AC_SUBST of EXEEXT.
498 * configure: Regenerate.
500 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>
502 * aclocal.m4: new file for AM_EXEEXT macro
503 * configure.in: call AM_EXEEXT

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

917 that the simulation be halted.
919 * psim.c (psim_options): Add hack to -i option to optionally
920 include a level vis -i2.
921 (psim_usage): Document.

935 (event_queue_init): Start the event queue out with processing
937 (event_queue_tick): Check that processing isn't still being
940 * gen-idecode.c (print_run_until_stop_body): Call
941 event_queue_process_events to clear possibly pending events before

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

1018 * gen-icache.c (print_icache_extraction): For a cache entry of
1019 the form <name>_is_<const> where it is a boolean field, generate
1020 the result of the expression instead of the expression its self.

1022 then generating corresponding definitions.
1024 * gen-icache.c (print_icache_struct): If there is no cache, do not
1025 output expressions in idecode.h file.

1034 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1036 * The code that put values in and extracted values from the cache
1037 was too compilicated. The cache table did not allow values to be
1038 computed from cache entries. #defines could only be used when a
1039 cache was present, remove the restriction.
1041 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1042 scratch variable is defined when a cache entry is beinf
1043 filled. Change the definition of a COMPUTE variable to be defined
1044 when the cache entry is being used.
1045 * gen-icache.c: Update.
1047 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1048 is more obvious. old_name->field_name, new_name->derived_name.
1049 * gen-icache.c: Update
1051 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1052 different types of cache code - put into cache, extract from
1053 cache, no cache - an explicit argument to print_icache_body.
1054 * gen-icache.c (print_icache_extraction): Ditto.
1056 * gen-semantics.c (print_c_semantic): Update use.
1057 * gen-idecode.c (print_jump_insn): Update use.
1058 * gen-icache.c (print_icache_function): Update use.
1060 * igen.c (main): Change 'R' option so that it does not force the
1063 * configure.in (enable-sim-icache): Clarify description. Make
