280 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
282 * sim-endian.h: Don't have parameters on macro definitions which
283 are simply renaming functions, to permit use of XCONCAT2 in both
284 the macro name and the arguments in a use of such a definition.
286 2000-11-15 Jim Blandy <jimb@redhat.com>
288 * sim_calls.c: Doc fix.
289 (sim_fetch_register, sim_store_register): Call

324 1999-05-08 Felix Lee <flee@cygnus.com>
326 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.

329 1999-04-02 Keith Seitz <keiths@cygnus.com>

335 after the specified POLL_QUIT_INTERVAL.
337 1999-02-22 Jim Lemke <jlemke@cygnus.com>
339 * dc-complex: Force expansion on all bits of field BO.

347 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
349 Make the simulator compatible with the MPC750. It would be nicer
350 to make this a real multi-sim, but that's more work than we have
352 * emul_generic.c (emul_add_tree_options): Only require strict
353 alignment if it was explicitly requested at configuration time.
354 Don't make it the default for little-endian machines.
355 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
356 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
357 THRM2, THRM3): Plop in the MPC750 SPR registers.
358 (DABR): This is weird. This was HID5, but the PPC spec says this
359 should be DABR; why did some random processor use it for something
360 else? The HID5 entry dates back to the original checkin of the
361 simulator code in 1995, so remove it.
362 * sim_calls.c (register_names): Delete this; since the user can
363 now change GDB's list of register names dynamically, we can't
364 pretend there's a static mapping here.
365 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
366 function to get the register name. That ought to be accurate.
367 However, we're changing a compile-time dependency (using the
368 REGISTER_NAMES macro) into a link- and run-time dependency
369 (calling REGISTER_NAME, which happens to be a function call on the
372 1999-01-22 Jim Lemke <jlemke@cygnus.com>
374 * igen.c(gen_semantics_[ch]): setup/use of new option

378 psim.c(is_num - added, psim_options): Parse and init new option.
379 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

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

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

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

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

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

1006 * igen.c (main): Change 'R' option so that it does not force the
1009 * configure.in (enable-sim-icache): Clarify description. Make
1010 #define one of the defaults regardless of the cache. Probably
1011 should revamp and add a separate option.
1013 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1015 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
