275 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
277 * sim-endian.h: Don't have parameters on macro definitions which
278 are simply renaming functions, to permit use of XCONCAT2 in both
279 the macro name and the arguments in a use of such a definition.
281 2000-11-15 Jim Blandy <jimb@redhat.com>
283 * sim_calls.c: Doc fix.
284 (sim_fetch_register, sim_store_register): Call

315 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
317 * configure: Regenerated to track ../common/aclocal.m4 changes.
319 1999-05-08 Felix Lee <flee@cygnus.com>
321 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
322 * configure: Regenerated to track ../common/aclocal.m4 changes.
324 1999-04-02 Keith Seitz <keiths@cygnus.com>

330 after the specified POLL_QUIT_INTERVAL.
332 1999-02-22 Jim Lemke <jlemke@cygnus.com>
334 * dc-complex: Force expansion on all bits of field BO.
335 Previously, the least-significant (prediction) bit was ignored.
336 * ppc-instructions (conditional branches): Implement mpc860c0 option.

342 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
344 Make the simulator compatible with the MPC750. It would be nicer
345 to make this a real multi-sim, but that's more work than we have
347 * emul_generic.c (emul_add_tree_options): Only require strict
348 alignment if it was explicitly requested at configuration time.
349 Don't make it the default for little-endian machines.
350 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
351 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
352 THRM2, THRM3): Plop in the MPC750 SPR registers.
353 (DABR): This is weird. This was HID5, but the PPC spec says this
354 should be DABR; why did some random processor use it for something
355 else? The HID5 entry dates back to the original checkin of the
356 simulator code in 1995, so remove it.
357 * sim_calls.c (register_names): Delete this; since the user can
358 now change GDB's list of register names dynamically, we can't
359 pretend there's a static mapping here.
360 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
361 function to get the register name. That ought to be accurate.
362 However, we're changing a compile-time dependency (using the
363 REGISTER_NAMES macro) into a link- and run-time dependency
364 (calling REGISTER_NAME, which happens to be a function call on the
367 1999-01-22 Jim Lemke <jlemke@cygnus.com>
369 * igen.c(gen_semantics_[ch]): setup/use of new option
371 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.

373 psim.c(is_num - added, psim_options): Parse and init new option.
374 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
376 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
378 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

389 poll the external environment.
391 1998-11-19 Michael Meissner <meissner@cygnus.com>
393 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
394 fractional type, so that quiet NaN's aren't treated like
397 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
399 * table.c (table_open): For cygwin hosts, we need to use the
400 return value from the read routine as the number of bytes to
401 process. This apparently is due to text-mode vs binary-mode. If
402 the mounts are done text-mode, then the size returnedby fstat()
403 may be different than the number of bytes "read" in text mode.
405 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
407 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

414 * emul_{netbsd,unix}.c: Update copyright year.
416 Mon Jun 29 10:57:36 1998 Michael Snyder <msnyder@cleaver.cygnus.com>
418 * sim_calls.c (sim_fetch_register, sim_store_register):
419 return zero when nothing to do.
421 1998-06-26 Michael Meissner <meissner@cygnus.com>
423 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
424 * configure: Regenerate.
425 * emul_{netbsd,unix}.c (toplevel): No longer try to include
426 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
428 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
430 * Makefile.in: The run target depended on a target psim$(EXEEXT),
431 but there was no such target, only plain psim. So I changed the
432 run target to depend on psim.
434 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
436 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
437 now defined in ../common/aclocal.m4, and the double definition causes
438 problems with AC_SUBST of EXEEXT.

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

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

887 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
890 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

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

960 the form <name>_is_<const> where it is a boolean field, generate

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

1001 * igen.c (main): Change 'R' option so that it does not force the
1004 * configure.in (enable-sim-icache): Clarify description. Make
1005 #define one of the defaults regardless of the cache. Probably
1006 should revamp and add a separate option.
1008 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1010 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1021 device after it was deleted. Instead add and remove cap's from the
1022 cap db as they are created and deleted. This ensuring that a
1023 capibility is only used during the lifetime of the corresponding
1026 * cap.h, cap.c: Correct cap type - was signed32 should be
1029 * cap.c (cap_add, cap_remove): New methods for cap object that
1030 allow the explicit addition and removal of internal objects that
1031 the cap knows about.

1034 remaining in the cap data base are those that were entered first.
1035 Thse objects will be the permenant ones.
1036 * device.c (device_init_address): Remember to initialize the cap
1039 * device.c (device_create_instance_from): Explicitly add device
1040 instances to the cap database. Simplify create code.

2477 * igen.c: Add option (-C) to generate semantics in the instruction
2480 * configure.in (--enable-sim-icache): Accept an option list such
2481 as 1024,define. Add a new choice to the list - semantic - which

2487 * configure.in: New option --enable-sim-line-nr (default enabled).

2542 * Makefile.in (filter.o): Adjust
2543 * configure.in: Adjust filter flag so that default includes 32bit
