292 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
294 * sim-endian.h: Don't have parameters on macro definitions which
295 are simply renaming functions, to permit use of XCONCAT2 in both
296 the macro name and the arguments in a use of such a definition.
298 2000-11-15 Jim Blandy <jimb@redhat.com>
300 * sim_calls.c: Doc fix.
301 (sim_fetch_register, sim_store_register): Call

332 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
334 * configure: Regenerated to track ../common/aclocal.m4 changes.
336 1999-05-08 Felix Lee <flee@cygnus.com>
338 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
339 * configure: Regenerated to track ../common/aclocal.m4 changes.
341 1999-04-02 Keith Seitz <keiths@cygnus.com>

347 after the specified POLL_QUIT_INTERVAL.
349 1999-02-22 Jim Lemke <jlemke@cygnus.com>
351 * dc-complex: Force expansion on all bits of field BO.
352 Previously, the least-significant (prediction) bit was ignored.

359 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
361 Make the simulator compatible with the MPC750. It would be nicer
362 to make this a real multi-sim, but that's more work than we have
364 * emul_generic.c (emul_add_tree_options): Only require strict
365 alignment if it was explicitly requested at configuration time.
366 Don't make it the default for little-endian machines.
367 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
368 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
369 THRM2, THRM3): Plop in the MPC750 SPR registers.
370 (DABR): This is weird. This was HID5, but the PPC spec says this
371 should be DABR; why did some random processor use it for something
372 else? The HID5 entry dates back to the original checkin of the
373 simulator code in 1995, so remove it.
374 * sim_calls.c (register_names): Delete this; since the user can
375 now change GDB's list of register names dynamically, we can't
376 pretend there's a static mapping here.
377 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
378 function to get the register name. That ought to be accurate.
379 However, we're changing a compile-time dependency (using the
380 REGISTER_NAMES macro) into a link- and run-time dependency
381 (calling REGISTER_NAME, which happens to be a function call on the
384 1999-01-22 Jim Lemke <jlemke@cygnus.com>
386 * igen.c(gen_semantics_[ch]): setup/use of new option

390 psim.c(is_num - added, psim_options): Parse and init new option.
391 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
393 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
395 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

406 poll the external environment.
408 1998-11-19 Michael Meissner <meissner@cygnus.com>
410 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
411 fractional type, so that quiet NaN's aren't treated like
414 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
416 * table.c (table_open): For cygwin hosts, we need to use the
417 return value from the read routine as the number of bytes to
418 process. This apparently is due to text-mode vs binary-mode. If
419 the mounts are done text-mode, then the size returnedby fstat()
420 may be different than the number of bytes "read" in text mode.
422 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
424 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

435 * sim_calls.c (sim_fetch_register, sim_store_register):
436 return zero when nothing to do.
438 1998-06-26 Michael Meissner <meissner@cygnus.com>
440 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
441 * configure: Regenerate.
442 * emul_{netbsd,unix}.c (toplevel): No longer try to include
443 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
445 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
447 * Makefile.in: The run target depended on a target psim$(EXEEXT),
448 but there was no such target, only plain psim. So I changed the
449 run target to depend on psim.
451 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
453 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
454 now defined in ../common/aclocal.m4, and the double definition causes
455 problems with AC_SUBST of EXEEXT.

458 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>

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

927 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
928 to be initialized independant of the rest of the simulation

930 could be overridden by hw_trace.
932 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
934 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
935 debug.c. It could be much simpler.
937 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

994 * The code that put values in and extracted values from the cache
995 was too compilicated. The cache table did not allow values to be
996 computed from cache entries. #defines could only be used when a
997 cache was present, remove the restriction.
999 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1000 scratch variable is defined when a cache entry is beinf
1001 filled. Change the definition of a COMPUTE variable to be defined
1002 when the cache entry is being used.
1003 * gen-icache.c: Update.
1005 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1006 is more obvious. old_name->field_name, new_name->derived_name.
1007 * gen-icache.c: Update

1018 * igen.c (main): Change 'R' option so that it does not force the
1021 * configure.in (enable-sim-icache): Clarify description. Make
1022 #define one of the defaults regardless of the cache. Probably
1023 should revamp and add a separate option.
1025 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1027 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
