162 are simply renaming functions, to permit use of XCONCAT2 in both
163 the macro name and the arguments in a use of such a definition.
165 2000-11-15 Jim Blandy <jimb@redhat.com>
167 * sim_calls.c: Doc fix.
168 (sim_fetch_register, sim_store_register): Call

203 1999-05-08 Felix Lee <flee@cygnus.com>
205 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
206 * configure: Regenerated to track ../common/aclocal.m4 changes.
208 1999-04-02 Keith Seitz <keiths@cygnus.com>

226 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
228 Make the simulator compatible with the MPC750. It would be nicer
229 to make this a real multi-sim, but that's more work than we have
231 * emul_generic.c (emul_add_tree_options): Only require strict
232 alignment if it was explicitly requested at configuration time.
233 Don't make it the default for little-endian machines.
234 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
235 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
236 THRM2, THRM3): Plop in the MPC750 SPR registers.
237 (DABR): This is weird. This was HID5, but the PPC spec says this
238 should be DABR; why did some random processor use it for something
239 else? The HID5 entry dates back to the original checkin of the
240 simulator code in 1995, so remove it.
241 * sim_calls.c (register_names): Delete this; since the user can
242 now change GDB's list of register names dynamically, we can't
243 pretend there's a static mapping here.
244 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
245 function to get the register name. That ought to be accurate.
246 However, we're changing a compile-time dependency (using the
247 REGISTER_NAMES macro) into a link- and run-time dependency
248 (calling REGISTER_NAME, which happens to be a function call on the
251 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

640 * Property create/initialization still wasn't correctly ordered.
641 Should be delaying everything related to ihandle creation until

721 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
723 * When performance monitoring is disabled, it is still possible to
724 determine the simulation speed by looking at the number of elapsed
725 ticks recorded by the event queue.
727 * psim.c (psim_write_register, psim_read_register): Force the cpu
728 to zero when it is either of `-1' or `nr_cpus'. In both cases the
729 next cpu would be zero any way.
731 * mon.c (mon_print_info): If possible, print the system cycle
732 performance. This is an indication of the number of instructions
735 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
737 * The code to allow an event queue to be updated during a signal
738 was missing. For main.c, a cntrl-c simulation termination wasn't
741 * The simulation would not correctly restart if an event requested
742 that the simulation be halted.
744 * psim.c (psim_options): Add hack to -i option to optionally
745 include a level vis -i2.
746 (psim_usage): Document.

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

839 as RA_is_0. If possible generate the result of the expression so
840 that the compiler gets a better chance of eliminating dead
843 * gen-icache.c (print_icache_extraction): For a cache entry of
844 the form <name>_is_<const> where it is a boolean field, generate
845 the result of the expression instead of the expression its self.

861 * The code that put values in and extracted values from the cache
862 was too compilicated. The cache table did not allow values to be
863 computed from cache entries. #defines could only be used when a
864 cache was present, remove the restriction.
866 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
867 scratch variable is defined when a cache entry is beinf
868 filled. Change the definition of a COMPUTE variable to be defined
869 when the cache entry is being used.
870 * gen-icache.c: Update.
872 * ld-cache.h, ld-cache.c: Change field names so that their meaning
873 is more obvious. old_name->field_name, new_name->derived_name.
874 * gen-icache.c: Update
876 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
877 different types of cache code - put into cache, extract from
878 cache, no cache - an explicit argument to print_icache_body.
879 * gen-icache.c (print_icache_extraction): Ditto.
881 * gen-semantics.c (print_c_semantic): Update use.
882 * gen-idecode.c (print_jump_insn): Update use.

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