138
139 * sim-endian.h: Don't have parameters on macro definitions which
140 are simply renaming functions, to permit use of XCONCAT2 in both

158Fri Apr 28 15:59:27 2000 Andrew Cagney <cagney@b1.cygnus.com>
159
160 * events.c (event_queue_process): Call update_time_from_event
161 every time an event is removed from the queue.

164
25d704f3

SS
1861999-04-02 Keith Seitz <keiths@cygnus.com>
187
188 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
189 the frequency at which the poll_quit callback is called.
190 (poll_quit_count): New global.
191 (sim_io_poll_quit): Only call the poll_quit callback
192 after the specified POLL_QUIT_INTERVAL.
193
1941999-02-22 Jim Lemke <jlemke@cygnus.com>
195

2041999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
205
206 Make the simulator compatible with the MPC750. It would be nicer
207 to make this a real multi-sim, but that's more work than we have
208 time for.
209 * emul_generic.c (emul_add_tree_options): Only require strict
210 alignment if it was explicitly requested at configuration time.
211 Don't make it the default for little-endian machines.
212 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
213 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
214 THRM2, THRM3): Plop in the MPC750 SPR registers.
215 (DABR): This is weird. This was HID5, but the PPC spec says this
216 should be DABR; why did some random processor use it for something
217 else? The HID5 entry dates back to the original checkin of the
218 simulator code in 1995, so remove it.
219 * sim_calls.c (register_names): Delete this; since the user can
220 now change GDB's list of register names dynamically, we can't
221 pretend there's a static mapping here.
222 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
223 function to get the register name. That ought to be accurate.
224 However, we're changing a compile-time dependency (using the
225 REGISTER_NAMES macro) into a link- and run-time dependency
226 (calling REGISTER_NAME, which happens to be a function call on the
227 PPC).
228
2291999-01-22 Jim Lemke <jlemke@cygnus.com>
230
231 * igen.c(gen_semantics_[ch]): setup/use of new option
232 (-o mpc860c0[=n]).
233 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
234 ppc-instructions(the four branch insn groups): detect problematic br's.
235 psim.c(is_num - added, psim_options): Parse and init new option.
236 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
237
2381998-12-01 Ken Raeburn <raeburn@cygnus.com>
239
240 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.
241
242Fri Nov 20 12:17:28 1998 Andrew Cagney <cagney@b1.cygnus.com>
243
244 * main.c (sim_io_poll_quit): Stub function.
245
246 * events.c (SIM_EVENTS_POLL_RATE): Define.
247 (sim_events_poll): Copy function from common/sim-events.c.
248 (event_queue_init): Copy scheduling of sim_events_poll from same.
249
250 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
251 poll the external environment.
252
2531998-11-19 Michael Meissner <meissner@cygnus.com>
254
255 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
256 fractional type, so that quiet NaN's aren't treated like
257 Infinities.
258
259Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
260
261 * table.c (table_open): For cygwin hosts, we need to use the
262 return value from the read routine as the number of bytes to
263 process. This apparently is due to text-mode vs binary-mode. If
264 the mounts are done text-mode, then the size returnedby fstat()
265 may be different than the number of bytes "read" in text mode.
266
267Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
268
269 * emul_netbsd.c (do_open): fix order-of-evaluation problem.
270 (do_close): ditto.
271 (do_fstat): ditto.
272 (do_lstat): ditto.
273
2741998-09-03 Michael Meissner <meissner@cygnus.com>
275
276 * emul_{netbsd,unix}.c: Update copyright year.
277
278Mon Jun 29 10:57:36 1998 Michael Snyder <msnyder@cleaver.cygnus.com>
279
280 * sim_calls.c (sim_fetch_register, sim_store_register):
281 return zero when nothing to do.
282
2831998-06-26 Michael Meissner <meissner@cygnus.com>
284
285 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
286 * configure: Regenerate.
287 * emul_{netbsd,unix}.c (toplevel): No longer try to include
288 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
289
290Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
291
292 * Makefile.in: The run target depended on a target psim$(EXEEXT),
293 but there was no such target, only plain psim. So I changed the
294 run target to depend on psim.
295
296Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
297
298 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
299 now defined in ../common/aclocal.m4, and the double definition causes
300 problems with AC_SUBST of EXEEXT.
301 * configure: Regenerate.

375
376Mon Oct 6 18:09:26 1997 Michael Meissner <meissner@cygnus.com>
377

657
658 * gen-idecode.c: Re-work the table lookup code so that it assumes

663 * gen-idecode.c: Correct generated igen body so that it no drops
664 or doubles clock interrupts.
665

701 * When performance monitoring is disabled, it is still possible to
702 determine the simulation speed by looking at the number of elapsed
703 ticks recorded by the event queue.
704
705 * psim.c (psim_write_register, psim_read_register): Force the cpu
706 to zero when it is either of `-1' or `nr_cpus'. In both cases the
707 next cpu would be zero any way.
708

710 performance. This is an indication of the number of instructions
711 per second.
712
713Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
714
715 * The code to allow an event queue to be updated during a signal
716 was missing. For main.c, a cntrl-c simulation termination wasn't
717 handled cleanly.
718
719 * The simulation would not correctly restart if an event requested
720 that the simulation be halted.
721
722 * psim.c (psim_options): Add hack to -i option to optionally
723 include a level vis -i2.
724 (psim_usage): Document.
725
726 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

739 false.
740 (event_queue_tick): Check that processing isn't still being
741 performed.
742
743 * gen-idecode.c (print_run_until_stop_body): Call
744 event_queue_process_events to clear possibly pending events before
745 starting a simulation run. Re-arange main loop so that simulator

753
754 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
755 RA. Based on instruction frequency stats, expand additional
756 instructions.
757 * ppc-instructions: Change all `RA == 0' to RA_is_0.
758
759 * ppc-opcode-stupid: Move all but the basic table in -complex into
760 here. Update to new format.

768 Implement.
769
770Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
771
772 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
773 to be initialized independant of the rest of the simulation
774 initalization. Otherwize a trace option explictly set from gdb
775 could be overridden by hw_trace.
776
777 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
778
779 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
780 debug.c. It could be much simpler.
781
782Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
783
784 * Some devices support removable media. Add hooks to the disk

815
816 * For expressions like (RA == 0) that are entered in to the cache
817 as RA_is_0. If possible generate the result of the expression so
818 that the compiler gets a better chance of eliminating dead
819 branches.
820
821 * gen-icache.c (print_icache_extraction): For a cache entry of
822 the form <name>_is_<const> where it is a boolean field, generate
823 the result of the expression instead of the expression its self.
824 (print_icache_body): Remove code that was looking for *_is_0 and
825 then generating corresponding definitions.
826
827 * gen-icache.c (print_icache_struct): If there is no cache, do not
828 output expressions in idecode.h file.
829
830 * gen-icache.c (print_icache_body): Output them here.
831

835 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
836
837Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
838
839 * The code that put values in and extracted values from the cache
840 was too compilicated. The cache table did not allow values to be
841 computed from cache entries. #defines could only be used when a
842 cache was present, remove the restriction.
843
844 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
845 scratch variable is defined when a cache entry is beinf
846 filled. Change the definition of a COMPUTE variable to be defined

858
859 * gen-semantics.c (print_c_semantic): Update use.
860 * gen-idecode.c (print_jump_insn): Update use.
861 * gen-icache.c (print_icache_function): Update use.
862
863 * igen.c (main): Change 'R' option so that it does not force the
864 cache.
865
866 * configure.in (enable-sim-icache): Clarify description. Make
867 #define one of the defaults regardless of the cache. Probably
868 should revamp and add a separate option.
869
870Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

881
882 * The cap object was retaining a reference to the instance of a
883 device after it was deleted. Instead add and remove cap's from the
884 cap db as they are created and deleted. This ensuring that a
885 capibility is only used during the lifetime of the corresponding
886 object.
887
888 * cap.h, cap.c: Correct cap type - was signed32 should be
889 signed_cell.
890
891 * cap.c (cap_add, cap_remove): New methods for cap object that
892 allow the explicit addition and removal of internal objects that
893 the cap knows about.
894
895 * cap.c (cap_init): Rewrite. Verify that the only objects
896 remaining in the cap data base are those that were entered first.
897 Thse objects will be the permenant ones.
898 * device.c (device_init_address): Remember to initialize the cap
899 database.
