270
271 * sim-endian.h: Don't have parameters on macro definitions which

319

321 the frequency at which the poll_quit callback is called.
322 (poll_quit_count): New global.
323 (sim_io_poll_quit): Only call the poll_quit callback
324 after the specified POLL_QUIT_INTERVAL.
325
3261999-02-22 Jim Lemke <jlemke@cygnus.com>
327
328 * dc-complex: Force expansion on all bits of field BO.
329 Previously, the least-significant (prediction) bit was ignored.

3361999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
337
338 Make the simulator compatible with the MPC750. It would be nicer
339 to make this a real multi-sim, but that's more work than we have
340 time for.
341 * emul_generic.c (emul_add_tree_options): Only require strict
342 alignment if it was explicitly requested at configuration time.
343 Don't make it the default for little-endian machines.
344 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
345 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
346 THRM2, THRM3): Plop in the MPC750 SPR registers.
347 (DABR): This is weird. This was HID5, but the PPC spec says this
348 should be DABR; why did some random processor use it for something
349 else? The HID5 entry dates back to the original checkin of the
350 simulator code in 1995, so remove it.
351 * sim_calls.c (register_names): Delete this; since the user can
352 now change GDB's list of register names dynamically, we can't
353 pretend there's a static mapping here.
354 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
355 function to get the register name. That ought to be accurate.
356 However, we're changing a compile-time dependency (using the
357 REGISTER_NAMES macro) into a link- and run-time dependency
358 (calling REGISTER_NAME, which happens to be a function call on the
359 PPC).
360
3611999-01-22 Jim Lemke <jlemke@cygnus.com>
362
363 * igen.c(gen_semantics_[ch]): setup/use of new option
364 (-o mpc860c0[=n]).
365 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
366 ppc-instructions(the four branch insn groups): detect problematic br's.
367 psim.c(is_num - added, psim_options): Parse and init new option.
368 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
369
3701998-12-01 Ken Raeburn <raeburn@cygnus.com>
371
372 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

380 (event_queue_init): Copy scheduling of sim_events_poll from same.
381
382 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
383 poll the external environment.
384
3851998-11-19 Michael Meissner <meissner@cygnus.com>
386
387 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
388 fractional type, so that quiet NaN's aren't treated like
389 Infinities.
390
391Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
392
393 * table.c (table_open): For cygwin hosts, we need to use the
394 return value from the read routine as the number of bytes to
395 process. This apparently is due to text-mode vs binary-mode. If
396 the mounts are done text-mode, then the size returnedby fstat()
397 may be different than the number of bytes "read" in text mode.
398
399Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
400
401 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

409
410Mon Jun 29 10:57:36 1998 Michael Snyder <msnyder@cleaver.cygnus.com>
411
412 * sim_calls.c (sim_fetch_register, sim_store_register):
413 return zero when nothing to do.
414
4151998-06-26 Michael Meissner <meissner@cygnus.com>
416
417 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
418 * configure: Regenerate.
419 * emul_{netbsd,unix}.c (toplevel): No longer try to include
420 sys/mount.h. It conflicts on Linux when gnu libc2 is used.

907 could be overridden by hw_trace.
908
909 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
910
911 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,

1018 object.
1019

2278
2279 * std-config.h (SEMANTICS_INLINE): By default, mask out the
2280 inlining of semantic functions from DEFAULT_INLINE. Almost all
2281 configurations call the semantic code via a pointer so there is
2282 little benefit.

2285
2286Thu Jul 25 20:07:30 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

2312 always update the cache_entries semantic and address fields.
2313
2314 * gen-idecode.c (print_idecode_switch_illegal): Include a break
2315 when generating illegal instructions. This was commented out
2316 which is a hangover from looking a at switch statements generated
2317 using indirect jumps.
2318
2319Tue Jul 23 20:57:01 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

2328 support.h so that, like cpu, it is optionally inlined for all
2329 modules that include it.
2330 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2331 same as cpu.[hc].
2332
2333 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2334 name for a lable and then branch to it.
2335
2336 * ppc-instructions (convert_to_integer, Floating Round to
2337 Single-Precision, Floating Convert from Integer Doubleword): Use
2338 LABEL and GOTO instead of the recently added switch statements.
2339
2340Wed Jul 24 14:02:42 1996 Andrew Cagney <cagney@sawnoff.highland.com.au>
2341
2342 * gen-idecode.c (print_run_until_stop_body): Too many rparen in

2360 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
2361 hardware instead of checking it using ls. configure.in should
2362 have taken care of any problems.
2363 (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
2364
2365Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
2366
2367 * psim.c (psim_options): Enter the argument to the memory size
2368 option directly into the device tree. Was using atol() which is

2372
2373 * configure.in (icache): Extend icache flag to include an insn

2389
2390Mon Jul 22 20:00:25 1996 Andrew Cagney <cagney@highland.com.au>
2391
2392 * emul_generic.c (emul_add_tree_options): Was incorrectly setting
2393 the strict-alignment option when hardwired for non-strict
2394 alignment.
2395
2396Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2397
2398 * gen-semantics.c: Make the my_index variable a macro MY_INDEX.

2404
2405 * gen-idecode.c: Output the complete run_until_stop function
2406 instead of just the code to handle a single instruction issue.
2407 * : Have the generated idecode.c include inline.c (instead of psim.c).
2408
2409 * std-config.h: Change psim.c so that it isn't inlined (as this is
2410 no longer needed).
2411
2412 * psim.c (run_until_stop): Delete the old run_until_stop function
2413 instead calling the idecode_run and idecode_run_until_stop
2414 functions that gen-idecode.c is now creating.
2415
2416Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2417
2418 * dgen.c: Maintenance - update to use new features found in lf.c.

2441 corresponding call to ITRACE so that it still matches.
2442
2443 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead

2448
2449 * gen-idecode.c (print_jump_until_stop_body): New function and
2450 idecode generation option. Instead of generating and calling

2464 testing jumping idecodes.
2465

2472 decode functions.
2473
2474 * configure.in (--enable-sim-icache): Accept an option list such
2475 as 1024,define. Add a new choice to the list - semantic - which
2476 will cause igen to generate instruction decode functions that
2477 include the corresponding semantic code.
2478
2479Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2480
2481 * configure.in: New option --enable-sim-line-nr (default enabled).
2482 Enable/disable the inclusion of CPP line directives in the
2483 generated files. Such directives refer back to the source files
2484 used when generating the simulator code.

2496
2497 * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
2498 that they use the same technique as igen (ie a dummy targets
2499 tmp-pk and tmp-hw are created).
2500
2501Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2502
2503 * Makefile.in (BUILD_CFLAGS): Include WARNING_CFLAGS.

2613 core object.
2614
