192 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
194 * sim-endian.h: Don't have parameters on macro definitions which
195 are simply renaming functions, to permit use of XCONCAT2 in both
196 the macro name and the arguments in a use of such a definition.
198 2000-11-15 Jim Blandy <jimb@redhat.com>
200 * sim_calls.c: Doc fix.
201 (sim_fetch_register, sim_store_register): Call

236 1999-05-08 Felix Lee <flee@cygnus.com>
238 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
239 * configure: Regenerated to track ../common/aclocal.m4 changes.
241 1999-04-02 Keith Seitz <keiths@cygnus.com>

247 after the specified POLL_QUIT_INTERVAL.
249 1999-02-22 Jim Lemke <jlemke@cygnus.com>
251 * dc-complex: Force expansion on all bits of field BO.

259 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
261 Make the simulator compatible with the MPC750. It would be nicer
262 to make this a real multi-sim, but that's more work than we have
264 * emul_generic.c (emul_add_tree_options): Only require strict
265 alignment if it was explicitly requested at configuration time.
266 Don't make it the default for little-endian machines.
267 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
268 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
269 THRM2, THRM3): Plop in the MPC750 SPR registers.
270 (DABR): This is weird. This was HID5, but the PPC spec says this
271 should be DABR; why did some random processor use it for something
272 else? The HID5 entry dates back to the original checkin of the
273 simulator code in 1995, so remove it.
274 * sim_calls.c (register_names): Delete this; since the user can
275 now change GDB's list of register names dynamically, we can't
276 pretend there's a static mapping here.
277 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
278 function to get the register name. That ought to be accurate.
279 However, we're changing a compile-time dependency (using the
280 REGISTER_NAMES macro) into a link- and run-time dependency
281 (calling REGISTER_NAME, which happens to be a function call on the
284 1999-01-22 Jim Lemke <jlemke@cygnus.com>
286 * igen.c(gen_semantics_[ch]): setup/use of new option

291 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
293 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
295 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

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

331 * emul_{netbsd,unix}.c: Update copyright year.
333 Mon Jun 29 10:57:36 1998 Michael Snyder <msnyder@cleaver.cygnus.com>
335 * sim_calls.c (sim_fetch_register, sim_store_register):
336 return zero when nothing to do.
338 1998-06-26 Michael Meissner <meissner@cygnus.com>
340 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
341 * configure: Regenerate.
342 * emul_{netbsd,unix}.c (toplevel): No longer try to include
343 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
345 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
347 * Makefile.in: The run target depended on a target psim$(EXEEXT),
348 but there was no such target, only plain psim. So I changed the
349 run target to depend on psim.
351 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
353 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
354 now defined in ../common/aclocal.m4, and the double definition causes
355 problems with AC_SUBST of EXEEXT.

448 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
450 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,
452 * words.h: __int64 instead of long long for MSVC.

673 * Property create/initialization still wasn't correctly ordered.
674 Should be delaying everything related to ihandle creation until
675 after the rest of the tree has been established.
677 * device.c (device_find_ihandle_runtime_property): Update.
678 (device_add_ihandle_runtime_property): Update.

754 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
756 * When performance monitoring is disabled, it is still possible to
757 determine the simulation speed by looking at the number of elapsed
758 ticks recorded by the event queue.
760 * psim.c (psim_write_register, psim_read_register): Force the cpu
761 to zero when it is either of `-1' or `nr_cpus'. In both cases the
762 next cpu would be zero any way.
764 * mon.c (mon_print_info): If possible, print the system cycle
765 performance. This is an indication of the number of instructions
768 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
770 * The code to allow an event queue to be updated during a signal
771 was missing. For main.c, a cntrl-c simulation termination wasn't
774 * The simulation would not correctly restart if an event requested
775 that the simulation be halted.
777 * psim.c (psim_options): Add hack to -i option to optionally
778 include a level vis -i2.
779 (psim_usage): Document.

793 (event_queue_init): Start the event queue out with processing
795 (event_queue_tick): Check that processing isn't still being
798 * gen-idecode.c (print_run_until_stop_body): Call
799 event_queue_process_events to clear possibly pending events before

815 here. Update to new format.

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

830 could be overridden by hw_trace.
832 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
834 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
835 debug.c. It could be much simpler.
837 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
839 * Some devices support removable media. Add hooks to the disk

877 the form <name>_is_<const> where it is a boolean field, generate
878 the result of the expression instead of the expression its self.
879 (print_icache_body): Remove code that was looking for *_is_0 and
880 then generating corresponding definitions.
882 * gen-icache.c (print_icache_struct): If there is no cache, do not

894 * The code that put values in and extracted values from the cache
895 was too compilicated. The cache table did not allow values to be
896 computed from cache entries. #defines could only be used when a
897 cache was present, remove the restriction.
899 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
900 scratch variable is defined when a cache entry is beinf
901 filled. Change the definition of a COMPUTE variable to be defined
902 when the cache entry is being used.
903 * gen-icache.c: Update.
905 * ld-cache.h, ld-cache.c: Change field names so that their meaning
906 is more obvious. old_name->field_name, new_name->derived_name.
907 * gen-icache.c: Update
909 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
910 different types of cache code - put into cache, extract from

914 * gen-semantics.c (print_c_semantic): Update use.
915 * gen-idecode.c (print_jump_insn): Update use.

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

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

2235 always update the cache_entries semantic and address fields.

2291 option directly into the device tree. Was using atol() which is
2292 dangerously non portable.
2294 Mon Jul 22 22:17:08 1996 Andrew Cagney <cagney@highland.com.au>
2296 * configure.in (icache): Extend icache flag to include an insn

2335 * psim.c (run_until_stop): Delete the old run_until_stop function

2394 * igen.c: Add option (-C) to generate semantics in the instruction
2397 * configure.in (--enable-sim-icache): Accept an option list such
2398 as 1024,define. Add a new choice to the list - semantic - which

2404 * configure.in: New option --enable-sim-line-nr (default enabled).

2460 * configure.in: Adjust filter flag so that default includes 32bit
