264 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
266 * sim-endian.h: Don't have parameters on macro definitions which
267 are simply renaming functions, to permit use of XCONCAT2 in both
268 the macro name and the arguments in a use of such a definition.
270 2000-11-15 Jim Blandy <jimb@redhat.com>
272 * sim_calls.c: Doc fix.
273 (sim_fetch_register, sim_store_register): Call

308 1999-05-08 Felix Lee <flee@cygnus.com>
310 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
311 * configure: Regenerated to track ../common/aclocal.m4 changes.
313 1999-04-02 Keith Seitz <keiths@cygnus.com>

319 after the specified POLL_QUIT_INTERVAL.
321 1999-02-22 Jim Lemke <jlemke@cygnus.com>
323 * dc-complex: Force expansion on all bits of field BO.

331 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
333 Make the simulator compatible with the MPC750. It would be nicer
334 to make this a real multi-sim, but that's more work than we have
336 * emul_generic.c (emul_add_tree_options): Only require strict
337 alignment if it was explicitly requested at configuration time.
338 Don't make it the default for little-endian machines.
339 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
340 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
341 THRM2, THRM3): Plop in the MPC750 SPR registers.
342 (DABR): This is weird. This was HID5, but the PPC spec says this
343 should be DABR; why did some random processor use it for something
344 else? The HID5 entry dates back to the original checkin of the
345 simulator code in 1995, so remove it.
346 * sim_calls.c (register_names): Delete this; since the user can
347 now change GDB's list of register names dynamically, we can't
348 pretend there's a static mapping here.
349 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
350 function to get the register name. That ought to be accurate.
351 However, we're changing a compile-time dependency (using the
352 REGISTER_NAMES macro) into a link- and run-time dependency
353 (calling REGISTER_NAME, which happens to be a function call on the
356 1999-01-22 Jim Lemke <jlemke@cygnus.com>
358 * igen.c(gen_semantics_[ch]): setup/use of new option

363 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

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

407 * sim_calls.c (sim_fetch_register, sim_store_register):
408 return zero when nothing to do.
410 1998-06-26 Michael Meissner <meissner@cygnus.com>
412 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
413 * configure: Regenerate.
414 * emul_{netbsd,unix}.c (toplevel): No longer try to include
415 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
417 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
419 * Makefile.in: The run target depended on a target psim$(EXEEXT),
420 but there was no such target, only plain psim. So I changed the
421 run target to depend on psim.
423 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
425 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
426 now defined in ../common/aclocal.m4, and the double definition causes
427 problems with AC_SUBST of EXEEXT.

828 * When performance monitoring is disabled, it is still possible to
829 determine the simulation speed by looking at the number of elapsed
830 ticks recorded by the event queue.
832 * psim.c (psim_write_register, psim_read_register): Force the cpu
833 to zero when it is either of `-1' or `nr_cpus'. In both cases the
834 next cpu would be zero any way.
836 * mon.c (mon_print_info): If possible, print the system cycle
837 performance. This is an indication of the number of instructions
840 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
842 * The code to allow an event queue to be updated during a signal
843 was missing. For main.c, a cntrl-c simulation termination wasn't

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

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

949 the form <name>_is_<const> where it is a boolean field, generate
950 the result of the expression instead of the expression its self.

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

986 * gen-semantics.c (print_c_semantic): Update use.
987 * gen-idecode.c (print_jump_insn): Update use.

990 * igen.c (main): Change 'R' option so that it does not force the
993 * configure.in (enable-sim-icache): Clarify description. Make
994 #define one of the defaults regardless of the cache. Probably
995 should revamp and add a separate option.

999 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1010 device after it was deleted. Instead add and remove cap's from the
1011 cap db as they are created and deleted. This ensuring that a
1012 capibility is only used during the lifetime of the corresponding
1015 * cap.h, cap.c: Correct cap type - was signed32 should be
1018 * cap.c (cap_add, cap_remove): New methods for cap object that
1019 allow the explicit addition and removal of internal objects that
1020 the cap knows about.

1023 remaining in the cap data base are those that were entered first.
1024 Thse objects will be the permenant ones.
1025 * device.c (device_init_address): Remember to initialize the cap
1028 * device.c (device_create_instance_from): Explicitly add device
1029 instances to the cap database. Simplify create code.

2368 * configure.in (icache): Extend icache flag to include an insn

2466 * igen.c: Add option (-C) to generate semantics in the instruction
2469 * configure.in (--enable-sim-icache): Accept an option list such
2470 as 1024,define. Add a new choice to the list - semantic - which

2476 * configure.in: New option --enable-sim-line-nr (default enabled).

2531 * Makefile.in (filter.o): Adjust
2532 * configure.in: Adjust filter flag so that default includes 32bit
