183 are simply renaming functions, to permit use of XCONCAT2 in both
184 the macro name and the arguments in a use of such a definition.
186 2000-11-15 Jim Blandy <jimb@redhat.com>
188 * sim_calls.c: Doc fix.
189 (sim_fetch_register, sim_store_register): Call

224 1999-05-08 Felix Lee <flee@cygnus.com>
226 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
227 * configure: Regenerated to track ../common/aclocal.m4 changes.
229 1999-04-02 Keith Seitz <keiths@cygnus.com>

247 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
249 Make the simulator compatible with the MPC750. It would be nicer
250 to make this a real multi-sim, but that's more work than we have
252 * emul_generic.c (emul_add_tree_options): Only require strict
253 alignment if it was explicitly requested at configuration time.
254 Don't make it the default for little-endian machines.
255 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
256 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
257 THRM2, THRM3): Plop in the MPC750 SPR registers.
258 (DABR): This is weird. This was HID5, but the PPC spec says this
259 should be DABR; why did some random processor use it for something
260 else? The HID5 entry dates back to the original checkin of the
261 simulator code in 1995, so remove it.
262 * sim_calls.c (register_names): Delete this; since the user can
263 now change GDB's list of register names dynamically, we can't
264 pretend there's a static mapping here.
265 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
266 function to get the register name. That ought to be accurate.
267 However, we're changing a compile-time dependency (using the
268 REGISTER_NAMES macro) into a link- and run-time dependency
269 (calling REGISTER_NAME, which happens to be a function call on the
272 1999-01-22 Jim Lemke <jlemke@cygnus.com>

299 fractional type, so that quiet NaN's aren't treated like
302 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
304 * table.c (table_open): For cygwin hosts, we need to use the
305 return value from the read routine as the number of bytes to
306 process. This apparently is due to text-mode vs binary-mode. If
307 the mounts are done text-mode, then the size returnedby fstat()
308 may be different than the number of bytes "read" in text mode.
310 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
312 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

329 * configure: Regenerate.
330 * emul_{netbsd,unix}.c (toplevel): No longer try to include
331 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
333 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
335 * Makefile.in: The run target depended on a target psim$(EXEEXT),
336 but there was no such target, only plain psim. So I changed the
337 run target to depend on psim.
339 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
341 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
342 now defined in ../common/aclocal.m4, and the double definition causes
343 problems with AC_SUBST of EXEEXT.

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

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

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

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

882 * The code that put values in and extracted values from the cache
883 was too compilicated. The cache table did not allow values to be
884 computed from cache entries. #defines could only be used when a
885 cache was present, remove the restriction.
887 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
888 scratch variable is defined when a cache entry is beinf
889 filled. Change the definition of a COMPUTE variable to be defined
890 when the cache entry is being used.
891 * gen-icache.c: Update.
893 * ld-cache.h, ld-cache.c: Change field names so that their meaning
894 is more obvious. old_name->field_name, new_name->derived_name.
895 * gen-icache.c: Update
897 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
898 different types of cache code - put into cache, extract from

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