361 Make the simulator compatible with the MPC750. It would be nicer
362 to make this a real multi-sim, but that's more work than we have
363 time for.
364 * emul_generic.c (emul_add_tree_options): Only require strict
365 alignment if it was explicitly requested at configuration time.
366 Don't make it the default for little-endian machines.
367 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
368 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
369 THRM2, THRM3): Plop in the MPC750 SPR registers.
370 (DABR): This is weird. This was HID5, but the PPC spec says this
371 should be DABR; why did some random processor use it for something
372 else? The HID5 entry dates back to the original checkin of the
373 simulator code in 1995, so remove it.
374 * sim_calls.c (register_names): Delete this; since the user can
375 now change GDB's list of register names dynamically, we can't
376 pretend there's a static mapping here.
377 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
378 function to get the register name. That ought to be accurate.
379 However, we're changing a compile-time dependency (using the
380 REGISTER_NAMES macro) into a link- and run-time dependency
381 (calling REGISTER_NAME, which happens to be a function call on the
382 PPC).
383
3841999-01-22 Jim Lemke <jlemke@cygnus.com>
385
386 * igen.c(gen_semantics_[ch]): setup/use of new option
387 (-o mpc860c0[=n]).
388 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
389 ppc-instructions(the four branch insn groups): detect problematic br's.
390 psim.c(is_num - added, psim_options): Parse and init new option.
391 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
392
3931998-12-01 Ken Raeburn <raeburn@cygnus.com>

402 (sim_events_poll): Copy function from common/sim-events.c.
403 (event_queue_init): Copy scheduling of sim_events_poll from same.
404
405 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
406 poll the external environment.
407
4081998-11-19 Michael Meissner <meissner@cygnus.com>
409
410 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
411 fractional type, so that quiet NaN's aren't treated like
412 Infinities.
413
414Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
415
416 * table.c (table_open): For cygwin hosts, we need to use the
417 return value from the read routine as the number of bytes to
418 process. This apparently is due to text-mode vs binary-mode. If
419 the mounts are done text-mode, then the size returnedby fstat()
420 may be different than the number of bytes "read" in text mode.

912 * ppc-instructions: Change all `RA == 0' to RA_is_0.
913
914 * ppc-opcode-stupid: Move all but the basic table in -complex into

926
927 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
928 to be initialized independant of the rest of the simulation
929 initalization. Otherwize a trace option explictly set from gdb
930 could be overridden by hw_trace.
931
932 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
933
934 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,

993
994 * The code that put values in and extracted values from the cache
995 was too compilicated. The cache table did not allow values to be
996 computed from cache entries. #defines could only be used when a
997 cache was present, remove the restriction.
998
999 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1000 scratch variable is defined when a cache entry is beinf

1013
1014 * gen-semantics.c (print_c_semantic): Update use.

1021 * configure.in (enable-sim-icache): Clarify description. Make
1022 #define one of the defaults regardless of the cache. Probably
1023 should revamp and add a separate option.

1037 * The cap object was retaining a reference to the instance of a
1038 device after it was deleted. Instead add and remove cap's from the

1040 capibility is only used during the lifetime of the corresponding
1041 object.
1042
1043 * cap.h, cap.c: Correct cap type - was signed32 should be
1044 signed_cell.
1045
1046 * cap.c (cap_add, cap_remove): New methods for cap object that
1047 allow the explicit addition and removal of internal objects that
1048 the cap knows about.

2252
2253 * gen-idecode.c (print_jump): Was always generating a jump back to
2254 idecode. Only necessary at tail of semantic code.
2255 (print_jump): Was always setting the processor's cia, even during
2256 startup when the processor was still undefined.

2301
2302 * std-config.h (SEMANTICS_INLINE): By default, mask out the
2303 inlining of semantic functions from DEFAULT_INLINE. Almost all
2304 configurations call the semantic code via a pointer so there is
2305 little benefit.

2308
2309Thu Jul 25 20:07:30 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

2335 always update the cache_entries semantic and address fields.
2336
2337 * gen-idecode.c (print_idecode_switch_illegal): Include a break
2338 when generating illegal instructions. This was commented out
2339 which is a hangover from looking a at switch statements generated
2340 using indirect jumps.
2341
2342Tue Jul 23 20:57:01 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

2351 support.h so that, like cpu, it is optionally inlined for all
2352 modules that include it.
2353 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2354 same as cpu.[hc].
2355
2356 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2357 name for a lable and then branch to it.
2358
2359 * ppc-instructions (convert_to_integer, Floating Round to
2360 Single-Precision, Floating Convert from Integer Doubleword): Use
2361 LABEL and GOTO instead of the recently added switch statements.
2362
2363Wed Jul 24 14:02:42 1996 Andrew Cagney <cagney@sawnoff.highland.com.au>
2364
2365 * gen-idecode.c (print_run_until_stop_body): Too many rparen in

2381 possible for user packages to be specified.
2382
2383 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
2384 hardware instead of checking it using ls. configure.in should
2385 have taken care of any problems.
2386 (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
2387
2388Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
2389
2390 * psim.c (psim_options): Enter the argument to the memory size
2391 option directly into the device tree. Was using atol() which is
2392 dangerously non portable.
2393

2395
2396 * configure.in (icache): Extend icache flag to include an insn

2412
2413Mon Jul 22 20:00:25 1996 Andrew Cagney <cagney@highland.com.au>
2414
2415 * emul_generic.c (emul_add_tree_options): Was incorrectly setting
2416 the strict-alignment option when hardwired for non-strict
2417 alignment.
2418
2419Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2420
2421 * gen-semantics.c: Make the my_index variable a macro MY_INDEX.

2427
2428 * gen-idecode.c: Output the complete run_until_stop function
2429 instead of just the code to handle a single instruction issue.
2430 * : Have the generated idecode.c include inline.c (instead of psim.c).
2431
2432 * std-config.h: Change psim.c so that it isn't inlined (as this is
2433 no longer needed).
2434
2435 * psim.c (run_until_stop): Delete the old run_until_stop function
2436 instead calling the idecode_run and idecode_run_until_stop
2437 functions that gen-idecode.c is now creating.

2464 corresponding call to ITRACE so that it still matches.
2465
2466 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead

2471
2472 * gen-idecode.c (print_jump_until_stop_body): New function and
2473 idecode generation option. Instead of generating and calling

2487 testing jumping idecodes.
2488

2496
2497 * configure.in (--enable-sim-icache): Accept an option list such

2499 will cause igen to generate instruction decode functions that
2500 include the corresponding semantic code.
2501
2502Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2503
2504 * configure.in: New option --enable-sim-line-nr (default enabled).
2505 Enable/disable the inclusion of CPP line directives in the
2506 generated files. Such directives refer back to the source files

2520 * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
2521 that they use the same technique as igen (ie a dummy targets
2522 tmp-pk and tmp-hw are created).
2523
2524Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2525

2636 core object.
2637
