188
189 * sim-endian.h: Don't have parameters on macro definitions which
190 are simply renaming functions, to permit use of XCONCAT2 in both
191 the macro name and the arguments in a use of such a definition.

208Fri Apr 28 15:59:27 2000 Andrew Cagney <cagney@b1.cygnus.com>
209
210 * events.c (event_queue_process): Call update_time_from_event
211 every time an event is removed from the queue.

2361999-04-02 Keith Seitz <keiths@cygnus.com>
237
238 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
239 the frequency at which the poll_quit callback is called.
240 (poll_quit_count): New global.
241 (sim_io_poll_quit): Only call the poll_quit callback
242 after the specified POLL_QUIT_INTERVAL.
243
2441999-02-22 Jim Lemke <jlemke@cygnus.com>
245

2541999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
255
256 Make the simulator compatible with the MPC750. It would be nicer
257 to make this a real multi-sim, but that's more work than we have
258 time for.
259 * emul_generic.c (emul_add_tree_options): Only require strict
260 alignment if it was explicitly requested at configuration time.
261 Don't make it the default for little-endian machines.
262 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
263 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
264 THRM2, THRM3): Plop in the MPC750 SPR registers.
265 (DABR): This is weird. This was HID5, but the PPC spec says this
266 should be DABR; why did some random processor use it for something
267 else? The HID5 entry dates back to the original checkin of the
268 simulator code in 1995, so remove it.
269 * sim_calls.c (register_names): Delete this; since the user can
270 now change GDB's list of register names dynamically, we can't
271 pretend there's a static mapping here.
272 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
273 function to get the register name. That ought to be accurate.
274 However, we're changing a compile-time dependency (using the
275 REGISTER_NAMES macro) into a link- and run-time dependency
276 (calling REGISTER_NAME, which happens to be a function call on the
277 PPC).
278
2791999-01-22 Jim Lemke <jlemke@cygnus.com>
280
281 * igen.c(gen_semantics_[ch]): setup/use of new option
282 (-o mpc860c0[=n]).
283 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
284 ppc-instructions(the four branch insn groups): detect problematic br's.
285 psim.c(is_num - added, psim_options): Parse and init new option.
286 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
287
2881998-12-01 Ken Raeburn <raeburn@cygnus.com>
289
290 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.
291
292Fri Nov 20 12:17:28 1998 Andrew Cagney <cagney@b1.cygnus.com>
293
294 * main.c (sim_io_poll_quit): Stub function.
295
296 * events.c (SIM_EVENTS_POLL_RATE): Define.
297 (sim_events_poll): Copy function from common/sim-events.c.
298 (event_queue_init): Copy scheduling of sim_events_poll from same.
299
300 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
301 poll the external environment.
302
3031998-11-19 Michael Meissner <meissner@cygnus.com>
304
305 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
306 fractional type, so that quiet NaN's aren't treated like
307 Infinities.
308
309Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
310
311 * table.c (table_open): For cygwin hosts, we need to use the
312 return value from the read routine as the number of bytes to
313 process. This apparently is due to text-mode vs binary-mode. If
314 the mounts are done text-mode, then the size returnedby fstat()
315 may be different than the number of bytes "read" in text mode.
316
317Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
318
319 * emul_netbsd.c (do_open): fix order-of-evaluation problem.
320 (do_close): ditto.
321 (do_fstat): ditto.
322 (do_lstat): ditto.
323

327
328Mon Jun 29 10:57:36 1998 Michael Snyder <msnyder@cleaver.cygnus.com>
329
330 * sim_calls.c (sim_fetch_register, sim_store_register):
331 return zero when nothing to do.
332
3331998-06-26 Michael Meissner <meissner@cygnus.com>
334
335 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
336 * configure: Regenerate.
337 * emul_{netbsd,unix}.c (toplevel): No longer try to include
338 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
339
340Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
341
342 * Makefile.in: The run target depended on a target psim$(EXEEXT),
343 but there was no such target, only plain psim. So I changed the
344 run target to depend on psim.
345
346Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
347
348 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
349 now defined in ../common/aclocal.m4, and the double definition causes
350 problems with AC_SUBST of EXEEXT.
351 * configure: Regenerate.
352
353Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>

422 that they are always correctly aligned.
423 (struct _core_mapping, core_map_attach, core_init,
424 new_core_mapping): Change free_buffer to type void*.
425

706 max iterations exceeded.
707
708 * gen-idecode.c: Re-work the table lookup code so that it assumes
709 that the entry is a leaf by default. Simplify the boolean table
710 entry code so that it involves a mask + test instead of shift +
711 shift + mask + test.

713 * gen-idecode.c: Correct generated igen body so that it no drops
714 or doubles clock interrupts.
715

760 performance. This is an indication of the number of instructions
761 per second.
762
763Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
764
765 * The code to allow an event queue to be updated during a signal
766 was missing. For main.c, a cntrl-c simulation termination wasn't
767 handled cleanly.
768
769 * The simulation would not correctly restart if an event requested
770 that the simulation be halted.
771
772 * psim.c (psim_options): Add hack to -i option to optionally
773 include a level vis -i2.
774 (psim_usage): Document.
775

790 (event_queue_tick): Check that processing isn't still being
791 performed.

803
804 * ppc-opcode-complex: Correct typo - was expanding ORA instead of

808
809 * ppc-opcode-stupid: Move all but the basic table in -complex into

821
822 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
823 to be initialized independant of the rest of the simulation
824 initalization. Otherwize a trace option explictly set from gdb
825 could be overridden by hw_trace.
826
827 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
828
829 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
830 debug.c. It could be much simpler.
831
832Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
833
834 * Some devices support removable media. Add hooks to the disk

867 as RA_is_0. If possible generate the result of the expression so
868 that the compiler gets a better chance of eliminating dead
869 branches.
870
871 * gen-icache.c (print_icache_extraction): For a cache entry of
872 the form <name>_is_<const> where it is a boolean field, generate
873 the result of the expression instead of the expression its self.
874 (print_icache_body): Remove code that was looking for *_is_0 and
875 then generating corresponding definitions.
876
877 * gen-icache.c (print_icache_struct): If there is no cache, do not
878 output expressions in idecode.h file.
879
880 * gen-icache.c (print_icache_body): Output them here.
881
882 * ppc-opcode-complex: Clarify constant values for SPR==LR register
883 expansion.
884
885 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
886
887Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
888
889 * The code that put values in and extracted values from the cache
890 was too compilicated. The cache table did not allow values to be
891 computed from cache entries. #defines could only be used when a
892 cache was present, remove the restriction.
893
894 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
895 scratch variable is defined when a cache entry is beinf
896 filled. Change the definition of a COMPUTE variable to be defined
897 when the cache entry is being used.
898 * gen-icache.c: Update.

2279 hardware instead of checking it using ls. configure.in should
2280 have taken care of any problems.

2282
2283Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
2284
2285 * psim.c (psim_options): Enter the argument to the memory size
2286 option directly into the device tree. Was using atol() which is

2322
2323 * gen-idecode.c: Output the complete run_until_stop function
2324 instead of just the code to handle a single instruction issue.
2325 * : Have the generated idecode.c include inline.c (instead of psim.c).
2326
2327 * std-config.h: Change psim.c so that it isn't inlined (as this is
2328 no longer needed).
2329
2330 * psim.c (run_until_stop): Delete the old run_until_stop function
2331 instead calling the idecode_run and idecode_run_until_stop
2332 functions that gen-idecode.c is now creating.

2359 corresponding call to ITRACE so that it still matches.
2360
2361 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
2362 of ITRACE. The CPP line directives would have previously set the

2366
2367 * gen-idecode.c (print_jump_until_stop_body): New function and
2368 idecode generation option. Instead of generating and calling

2382 testing jumping idecodes.
2383

2390 decode functions.
2391
2392 * configure.in (--enable-sim-icache): Accept an option list such
2393 as 1024,define. Add a new choice to the list - semantic - which
2394 will cause igen to generate instruction decode functions that
2395 include the corresponding semantic code.
2396
2397Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2398
2399 * configure.in: New option --enable-sim-line-nr (default enabled).

2401 generated files. Such directives refer back to the source files
2402 used when generating the simulator code.
2403
2404 * Makefile.in (sim_line_nr): Pass to igen.

2415 * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
2416 that they use the same technique as igen (ie a dummy targets
2417 tmp-pk and tmp-hw are created).
2418
2419Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2420
2421 * Makefile.in (BUILD_CFLAGS): Include WARNING_CFLAGS.
