143 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
145 * sim-endian.h: Don't have parameters on macro definitions which
146 are simply renaming functions, to permit use of XCONCAT2 in both
147 the macro name and the arguments in a use of such a definition.
149 2000-11-15 Jim Blandy <jimb@redhat.com>
151 * sim_calls.c: Doc fix.
152 (sim_fetch_register, sim_store_register): Call

187 1999-05-08 Felix Lee <flee@cygnus.com>
189 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
190 * configure: Regenerated to track ../common/aclocal.m4 changes.
192 1999-04-02 Keith Seitz <keiths@cygnus.com>

210 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
212 Make the simulator compatible with the MPC750. It would be nicer
213 to make this a real multi-sim, but that's more work than we have
215 * emul_generic.c (emul_add_tree_options): Only require strict
216 alignment if it was explicitly requested at configuration time.
217 Don't make it the default for little-endian machines.
218 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
219 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
220 THRM2, THRM3): Plop in the MPC750 SPR registers.
221 (DABR): This is weird. This was HID5, but the PPC spec says this
222 should be DABR; why did some random processor use it for something
223 else? The HID5 entry dates back to the original checkin of the
224 simulator code in 1995, so remove it.
225 * sim_calls.c (register_names): Delete this; since the user can
226 now change GDB's list of register names dynamically, we can't
227 pretend there's a static mapping here.
228 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
229 function to get the register name. That ought to be accurate.
230 However, we're changing a compile-time dependency (using the
231 REGISTER_NAMES macro) into a link- and run-time dependency
232 (calling REGISTER_NAME, which happens to be a function call on the
235 1999-01-22 Jim Lemke <jlemke@cygnus.com>

242 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
244 1998-12-01 Ken Raeburn <raeburn@cygnus.com>

257 poll the external environment.
259 1998-11-19 Michael Meissner <meissner@cygnus.com>
261 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
262 fractional type, so that quiet NaN's aren't treated like
265 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
267 * table.c (table_open): For cygwin hosts, we need to use the
268 return value from the read routine as the number of bytes to
269 process. This apparently is due to text-mode vs binary-mode. If
270 the mounts are done text-mode, then the size returnedby fstat()
271 may be different than the number of bytes "read" in text mode.
273 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
275 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

291 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
292 * configure: Regenerate.
293 * emul_{netbsd,unix}.c (toplevel): No longer try to include
294 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
296 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
298 * Makefile.in: The run target depended on a target psim$(EXEEXT),
299 but there was no such target, only plain psim. So I changed the
300 run target to depend on psim.
302 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
304 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
305 now defined in ../common/aclocal.m4, and the double definition causes
306 problems with AC_SUBST of EXEEXT.

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

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

845 * The code that put values in and extracted values from the cache
846 was too compilicated. The cache table did not allow values to be
847 computed from cache entries. #defines could only be used when a
848 cache was present, remove the restriction.
850 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
851 scratch variable is defined when a cache entry is beinf
852 filled. Change the definition of a COMPUTE variable to be defined
853 when the cache entry is being used.
854 * gen-icache.c: Update.
856 * ld-cache.h, ld-cache.c: Change field names so that their meaning
857 is more obvious. old_name->field_name, new_name->derived_name.

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

3275 * debug.h: Add trace_print_info, trace_print_device_tree and
3276 trace_dump_device_tree. The first is a replacement for the
3277 variable `print_info' found in main.c and sim_calls.c. The latter
3278 two enable the dumping of the entire device tree.

3335 * device.c (external_to_device) : New function that provides a
3336 standard mapping between a devices internal representation (a
3337 pointer) and its external (or what is passed to a client)
3338 representation (a phandle). Implement using the cap object
3339 attached to the root node.
