158 * sim_calls.c: Doc fix.

190 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
192 * configure: Regenerated to track ../common/aclocal.m4 changes.
194 1999-05-08 Felix Lee <flee@cygnus.com>
196 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
197 * configure: Regenerated to track ../common/aclocal.m4 changes.
199 1999-04-02 Keith Seitz <keiths@cygnus.com>

217 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
219 Make the simulator compatible with the MPC750. It would be nicer
220 to make this a real multi-sim, but that's more work than we have
222 * emul_generic.c (emul_add_tree_options): Only require strict
223 alignment if it was explicitly requested at configuration time.
224 Don't make it the default for little-endian machines.
225 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
226 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
227 THRM2, THRM3): Plop in the MPC750 SPR registers.
228 (DABR): This is weird. This was HID5, but the PPC spec says this
229 should be DABR; why did some random processor use it for something
230 else? The HID5 entry dates back to the original checkin of the
231 simulator code in 1995, so remove it.
232 * sim_calls.c (register_names): Delete this; since the user can
233 now change GDB's list of register names dynamically, we can't
234 pretend there's a static mapping here.
235 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
236 function to get the register name. That ought to be accurate.
237 However, we're changing a compile-time dependency (using the
238 REGISTER_NAMES macro) into a link- and run-time dependency
239 (calling REGISTER_NAME, which happens to be a function call on the
242 1999-01-22 Jim Lemke <jlemke@cygnus.com>
244 * igen.c(gen_semantics_[ch]): setup/use of new option

248 psim.c(is_num - added, psim_options): Parse and init new option.
249 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
251 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
253 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

263 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
264 poll the external environment.
266 1998-11-19 Michael Meissner <meissner@cygnus.com>
268 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
269 fractional type, so that quiet NaN's aren't treated like
272 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
274 * table.c (table_open): For cygwin hosts, we need to use the
275 return value from the read routine as the number of bytes to
276 process. This apparently is due to text-mode vs binary-mode. If
277 the mounts are done text-mode, then the size returnedby fstat()
278 may be different than the number of bytes "read" in text mode.
280 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
282 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

294 return zero when nothing to do.
296 1998-06-26 Michael Meissner <meissner@cygnus.com>
298 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
299 * configure: Regenerate.
300 * emul_{netbsd,unix}.c (toplevel): No longer try to include
301 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
303 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
305 * Makefile.in: The run target depended on a target psim$(EXEEXT),
306 but there was no such target, only plain psim. So I changed the
307 run target to depend on psim.
309 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
311 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
312 now defined in ../common/aclocal.m4, and the double definition causes
313 problems with AC_SUBST of EXEEXT.

631 * Property create/initialization still wasn't correctly ordered.
632 Should be delaying everything related to ihandle creation until
633 after the rest of the tree has been established.
635 * device.c (device_find_ihandle_runtime_property): Update.
636 (device_add_ihandle_runtime_property): Update.

712 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
714 * When performance monitoring is disabled, it is still possible to
715 determine the simulation speed by looking at the number of elapsed
716 ticks recorded by the event queue.
718 * psim.c (psim_write_register, psim_read_register): Force the cpu
719 to zero when it is either of `-1' or `nr_cpus'. In both cases the
720 next cpu would be zero any way.
722 * mon.c (mon_print_info): If possible, print the system cycle
723 performance. This is an indication of the number of instructions
726 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
728 * The code to allow an event queue to be updated during a signal
729 was missing. For main.c, a cntrl-c simulation termination wasn't
732 * The simulation would not correctly restart if an event requested
733 that the simulation be halted.

736 include a level vis -i2.
737 (psim_usage): Document.

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

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

852 * The code that put values in and extracted values from the cache
853 was too compilicated. The cache table did not allow values to be
854 computed from cache entries. #defines could only be used when a
855 cache was present, remove the restriction.
857 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
858 scratch variable is defined when a cache entry is beinf
859 filled. Change the definition of a COMPUTE variable to be defined
860 when the cache entry is being used.
861 * gen-icache.c: Update.
863 * ld-cache.h, ld-cache.c: Change field names so that their meaning
864 is more obvious. old_name->field_name, new_name->derived_name.
865 * gen-icache.c: Update
867 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
868 different types of cache code - put into cache, extract from

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