MM		 11998-11-19 Michael Meissner <meissner@cygnus.com>
2
3 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
4 fractional type, so that quiet NaN's aren't treated like
5 Infinities.

DM		 7Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
8
9 * table.c (table_open): For cygwin hosts, we need to use the return value
10 from the read routine as the number of bytes to process. This apparently
11 is due to text-mode vs binary-mode. If the mounts are done text-mode,
12 then the size returnedby fstat() may be different than the number of
13 bytes "read" in text mode.
14
15Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
16

37
38Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
39
40 * Makefile.in: The run target depended on a target psim$(EXEEXT),
41 but there was no such target, only plain psim. So I changed the

448
449 * When performance monitoring is disabled, it is still possible to
450 determine the simulation speed by looking at the number of elapsed
451 ticks recorded by the event queue.
452
453 * psim.c (psim_write_register, psim_read_register): Force the cpu
454 to zero when it is either of `-1' or `nr_cpus'. In both cases the
455 next cpu would be zero any way.
456
457 * mon.c (mon_print_info): If possible, print the system cycle
458 performance. This is an indication of the number of instructions
459 per second.
460
461Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
462
463 * The code to allow an event queue to be updated during a signal
464 was missing. For main.c, a cntrl-c simulation termination wasn't
465 handled cleanly.
466
467 * The simulation would not correctly restart if an event requested
468 that the simulation be halted.
469
470 * psim.c (psim_options): Add hack to -i option to optionally
471 include a level vis -i2.
472 (psim_usage): Document.
473
474 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
475 cntrl-c occures schedule an event to halt the simulation.

481 (event_queue_schedule_after_signal): Ditto.
482
483 * events.c (event_queue_process): Mark the event queue as being in
484 the processing state when processing has started. Adjust code
485 so that it is tolerant of halts.
486 (event_queue_init): Start the event queue out with processing
487 false.
488 (event_queue_tick): Check that processing isn't still being
489 performed.
490
491 * gen-idecode.c (print_run_until_stop_body): Call
492 event_queue_process_events to clear possibly pending events before
493 starting a simulation run. Re-arange main loop so that simulator

499
500Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
501
502 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
503 RA. Based on instruction frequency stats, expand additional
504 instructions.
505 * ppc-instructions: Change all `RA == 0' to RA_is_0.
506
507 * ppc-opcode-stupid: Move all but the basic table in -complex into
508 here. Update to new format.
509
510 * Makefile.in (tmp-defines): New target. Force defines.h to always
511 be built. Hence get ppc-opcode-goto to build.
512
513Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
514

MM		 518Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
519
520 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
521 to be initialized independant of the rest of the simulation
522 initalization. Otherwize a trace option explictly set from gdb
523 could be overridden by hw_trace.
524
525 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
526
527 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
528 debug.c. It could be much simpler.
529
530Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
531
532 * Some devices support removable media. Add hooks to the disk

543 media. If no file image is specified, use the next one in the
544 image property list.
545 (hw_disk_init_address): Change the file property so that it is a
546 string array - use the first entry for the initial file image.
547

549 string array.
550 (print_properties): Adjust.
551 (print_string): Write a string, handling double quotes.

563
564 * For expressions like (RA == 0) that are entered in to the cache
565 as RA_is_0. If possible generate the result of the expression so
566 that the compiler gets a better chance of eliminating dead
567 branches.
568
569 * gen-icache.c (print_icache_extraction): For a cache entry of
570 the form <name>_is_<const> where it is a boolean field, generate

573 then generating corresponding definitions.
574
575 * gen-icache.c (print_icache_struct): If there is no cache, do not
576 output expressions in idecode.h file.
577
578 * gen-icache.c (print_icache_body): Output them here.
579

581 expansion.
582
583 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
584
585Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
586
587 * The code that put values in and extracted values from the cache
588 was too compilicated. The cache table did not allow values to be
589 computed from cache entries. #defines could only be used when a
590 cache was present, remove the restriction.
591
592 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
593 scratch variable is defined when a cache entry is beinf
594 filled. Change the definition of a COMPUTE variable to be defined

596 * gen-icache.c: Update.
597
598 * ld-cache.h, ld-cache.c: Change field names so that their meaning

606
607 * gen-semantics.c (print_c_semantic): Update use.
608 * gen-idecode.c (print_jump_insn): Update use.
609 * gen-icache.c (print_icache_function): Update use.

611 * igen.c (main): Change 'R' option so that it does not force the
612 cache.
613
614 * configure.in (enable-sim-icache): Clarify description. Make
615 #define one of the defaults regardless of the cache. Probably
616 should revamp and add a separate option.
617
618Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

629
630 * The cap object was retaining a reference to the instance of a
631 device after it was deleted. Instead add and remove cap's from the
632 cap db as they are created and deleted. This ensuring that a
633 capibility is only used during the lifetime of the corresponding
634 object.
635
636 * cap.h, cap.c: Correct cap type - was signed32 should be
637 signed_cell.
638
639 * cap.c (cap_add, cap_remove): New methods for cap object that
640 allow the explicit addition and removal of internal objects that
641 the cap knows about.
642
643 * cap.c (cap_init): Rewrite. Verify that the only objects
644 remaining in the cap data base are those that were entered first.
645 Thse objects will be the permenant ones.

673
674 * hw_memory.c (hw_memory_instance_claim,
675 hw_memory_instance_release): Handle multi-cell memory devices.

1894
1895 * std-config.h (SEMANTICS_INLINE): By default, mask out the
1896 inlining of semantic functions from DEFAULT_INLINE. Almost all

1928 always update the cache_entries semantic and address fields.
1929
1930 * gen-idecode.c (print_idecode_switch_illegal): Include a break
1931 when generating illegal instructions. This was commented out
1932 which is a hangover from looking a at switch statements generated
1933 using indirect jumps.
1934

1945 modules that include it.
1946 * inline.h, inline.c: Adjust so that support.[hc] is handled the
1947 same as cpu.[hc].
1948
1949 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
1950 name for a lable and then branch to it.
1951
1952 * ppc-instructions (convert_to_integer, Floating Round to
1953 Single-Precision, Floating Convert from Integer Doubleword): Use
1954 LABEL and GOTO instead of the recently added switch statements.

1974 possible for user packages to be specified.
1975
1976 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
1977 hardware instead of checking it using ls. configure.in should
1978 have taken care of any problems.

1980
1981Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
1982
1983 * psim.c (psim_options): Enter the argument to the memory size
1984 option directly into the device tree. Was using atol() which is

2020
2021 * gen-idecode.c: Output the complete run_until_stop function
2022 instead of just the code to handle a single instruction issue.
2023 * : Have the generated idecode.c include inline.c (instead of psim.c).
2024
2025 * std-config.h: Change psim.c so that it isn't inlined (as this is
2026 no longer needed).
2027
2028 * psim.c (run_until_stop): Delete the old run_until_stop function
2029 instead calling the idecode_run and idecode_run_until_stop
2030 functions that gen-idecode.c is now creating.

2064
2065 * gen-idecode.c (print_jump_until_stop_body): New function and
2066 idecode generation option. Instead of generating and calling

2080 testing jumping idecodes.
2081

2096
2097 * configure.in: New option --enable-sim-line-nr (default enabled).

2112
2113 * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
2114 that they use the same technique as igen (ie a dummy targets
2115 tmp-pk and tmp-hw are created).
2116
2117Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2118

3076
3077 * device.c (external_to_device) : New function that provides a
3078 standard mapping between a devices internal representation (a
3079 pointer) and its external (or what is passed to a client)
3080 representation (a phandle). Implement using the cap object
3081 attached to the root node.
3082

3103
3104 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3105 read/write calls for buffer transfers. This will cause a fault to
3106 occure if the transfer fails. CHRP catches the fault while the
3107 others suffer the consequences.
