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

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

359 here. Update to new format.

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

397 string array - use the first entry for the initial file image.
399 * tree.c (print_string_aray_property): New function - print a

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

436 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
438 * The code that put values in and extracted values from the cache
439 was too compilicated. The cache table did not allow values to be
440 computed from cache entries. #defines could only be used when a
441 cache was present, remove the restriction.
443 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
444 scratch variable is defined when a cache entry is beinf
445 filled. Change the definition of a COMPUTE variable to be defined
446 when the cache entry is being used.
447 * gen-icache.c: Update.
449 * ld-cache.h, ld-cache.c: Change field names so that their meaning
450 is more obvious. old_name->field_name, new_name->derived_name.
451 * gen-icache.c: Update
453 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
454 different types of cache code - put into cache, extract from

458 * gen-semantics.c (print_c_semantic): Update use.
459 * gen-idecode.c (print_jump_insn): Update use.

462 * igen.c (main): Change 'R' option so that it does not force the
465 * configure.in (enable-sim-icache): Clarify description. Make
466 #define one of the defaults regardless of the cache. Probably
467 should revamp and add a separate option.

471 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

482 device after it was deleted. Instead add and remove cap's from the
483 cap db as they are created and deleted. This ensuring that a
484 capibility is only used during the lifetime of the corresponding
487 * cap.h, cap.c: Correct cap type - was signed32 should be
490 * cap.c (cap_add, cap_remove): New methods for cap object that
491 allow the explicit addition and removal of internal objects that

520 * The memory "claim" and "release" methods take an address and
521 size as arguments. These may be multi cell values. Initially fix
522 the memory code so that they check/detect this. Leave the
523 adjustment of any clients to later.

1840 * configure.in (icache): Extend icache flag to include an insn

1938 * igen.c: Add option (-C) to generate semantics in the instruction
1941 * configure.in (--enable-sim-icache): Accept an option list such
1942 as 1024,define. Add a new choice to the list - semantic - which

1948 * configure.in: New option --enable-sim-line-nr (default enabled).

2003 * Makefile.in (filter.o): Adjust
2004 * configure.in: Adjust filter flag so that default includes 32bit
