284 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
286 * sim-endian.h: Don't have parameters on macro definitions which
287 are simply renaming functions, to permit use of XCONCAT2 in both
288 the macro name and the arguments in a use of such a definition.
290 2000-11-15 Jim Blandy <jimb@redhat.com>
292 * sim_calls.c: Doc fix.
293 (sim_fetch_register, sim_store_register): Call

328 1999-05-08 Felix Lee <flee@cygnus.com>
330 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
331 * configure: Regenerated to track ../common/aclocal.m4 changes.
333 1999-04-02 Keith Seitz <keiths@cygnus.com>

339 after the specified POLL_QUIT_INTERVAL.
341 1999-02-22 Jim Lemke <jlemke@cygnus.com>
343 * dc-complex: Force expansion on all bits of field BO.

351 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
353 Make the simulator compatible with the MPC750. It would be nicer
354 to make this a real multi-sim, but that's more work than we have
356 * emul_generic.c (emul_add_tree_options): Only require strict
357 alignment if it was explicitly requested at configuration time.
358 Don't make it the default for little-endian machines.
359 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
360 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
361 THRM2, THRM3): Plop in the MPC750 SPR registers.
362 (DABR): This is weird. This was HID5, but the PPC spec says this
363 should be DABR; why did some random processor use it for something
364 else? The HID5 entry dates back to the original checkin of the
365 simulator code in 1995, so remove it.
366 * sim_calls.c (register_names): Delete this; since the user can
367 now change GDB's list of register names dynamically, we can't
368 pretend there's a static mapping here.
369 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
370 function to get the register name. That ought to be accurate.
371 However, we're changing a compile-time dependency (using the
372 REGISTER_NAMES macro) into a link- and run-time dependency
373 (calling REGISTER_NAME, which happens to be a function call on the
376 1999-01-22 Jim Lemke <jlemke@cygnus.com>
378 * igen.c(gen_semantics_[ch]): setup/use of new option

383 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

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

432 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
433 * configure: Regenerate.
434 * emul_{netbsd,unix}.c (toplevel): No longer try to include
435 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
437 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
439 * Makefile.in: The run target depended on a target psim$(EXEEXT),
440 but there was no such target, only plain psim. So I changed the
441 run target to depend on psim.
443 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
445 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
446 now defined in ../common/aclocal.m4, and the double definition causes
447 problems with AC_SUBST of EXEEXT.

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

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

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

1010 * igen.c (main): Change 'R' option so that it does not force the
1013 * configure.in (enable-sim-icache): Clarify description. Make
1014 #define one of the defaults regardless of the cache. Probably
1015 should revamp and add a separate option.
1017 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1019 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
