174 are simply renaming functions, to permit use of XCONCAT2 in both
175 the macro name and the arguments in a use of such a definition.
177 2000-11-15 Jim Blandy <jimb@redhat.com>
179 * sim_calls.c: Doc fix.

215 1999-05-08 Felix Lee <flee@cygnus.com>
217 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.

238 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
240 Make the simulator compatible with the MPC750. It would be nicer
241 to make this a real multi-sim, but that's more work than we have
243 * emul_generic.c (emul_add_tree_options): Only require strict
244 alignment if it was explicitly requested at configuration time.
245 Don't make it the default for little-endian machines.
246 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
247 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
248 THRM2, THRM3): Plop in the MPC750 SPR registers.
249 (DABR): This is weird. This was HID5, but the PPC spec says this
250 should be DABR; why did some random processor use it for something
251 else? The HID5 entry dates back to the original checkin of the
252 simulator code in 1995, so remove it.
253 * sim_calls.c (register_names): Delete this; since the user can
254 now change GDB's list of register names dynamically, we can't
255 pretend there's a static mapping here.
256 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
257 function to get the register name. That ought to be accurate.
258 However, we're changing a compile-time dependency (using the
259 REGISTER_NAMES macro) into a link- and run-time dependency
260 (calling REGISTER_NAME, which happens to be a function call on the
263 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

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

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

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

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

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

893 * gen-semantics.c (print_c_semantic): Update use.
894 * gen-idecode.c (print_jump_insn): Update use.

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