368 * When performance monitoring is disabled, it is still possible to
369 determine the simulation speed by looking at the number of elapsed
370 ticks recorded by the event queue.
372 * psim.c (psim_write_register, psim_read_register): Force the cpu
373 to zero when it is either of `-1' or `nr_cpus'. In both cases the
374 next cpu would be zero any way.
376 * mon.c (mon_print_info): If possible, print the system cycle
377 performance. This is an indication of the number of instructions
380 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
382 * The code to allow an event queue to be updated during a signal
383 was missing. For main.c, a cntrl-c simulation termination wasn't

405 (event_queue_init): Start the event queue out with processing
407 (event_queue_tick): Check that processing isn't still being
410 * gen-idecode.c (print_run_until_stop_body): Call
411 event_queue_process_events to clear possibly pending events before

416 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
419 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

439 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
440 to be initialized independant of the rest of the simulation
441 initalization. Otherwize a trace option explictly set from gdb
442 could be overridden by hw_trace.
444 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
446 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
447 debug.c. It could be much simpler.
449 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
451 * Some devices support removable media. Add hooks to the disk

489 the form <name>_is_<const> where it is a boolean field, generate
490 the result of the expression instead of the expression its self.

506 * The code that put values in and extracted values from the cache
507 was too compilicated. The cache table did not allow values to be
508 computed from cache entries. #defines could only be used when a
509 cache was present, remove the restriction.
511 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
512 scratch variable is defined when a cache entry is beinf
513 filled. Change the definition of a COMPUTE variable to be defined
514 when the cache entry is being used.
515 * gen-icache.c: Update.
517 * ld-cache.h, ld-cache.c: Change field names so that their meaning
518 is more obvious. old_name->field_name, new_name->derived_name.
519 * gen-icache.c: Update
521 * gen-icache.h, gen-icache.c (print_icache_body): Make the three

526 * gen-semantics.c (print_c_semantic): Update use.
527 * gen-idecode.c (print_jump_insn): Update use.

530 * igen.c (main): Change 'R' option so that it does not force the
533 * configure.in (enable-sim-icache): Clarify description. Make
534 #define one of the defaults regardless of the cache. Probably
535 should revamp and add a separate option.
537 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
539 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

550 device after it was deleted. Instead add and remove cap's from the
551 cap db as they are created and deleted. This ensuring that a
552 capibility is only used during the lifetime of the corresponding
555 * cap.h, cap.c: Correct cap type - was signed32 should be
558 * cap.c (cap_add, cap_remove): New methods for cap object that
559 allow the explicit addition and removal of internal objects that
562 * cap.c (cap_init): Rewrite. Verify that the only objects

2072 * configure.in: Adjust filter flag so that default includes 32bit
