399 * When performance monitoring is disabled, it is still possible to
400 determine the simulation speed by looking at the number of elapsed
401 ticks recorded by the event queue.
403 * psim.c (psim_write_register, psim_read_register): Force the cpu
404 to zero when it is either of `-1' or `nr_cpus'. In both cases the
405 next cpu would be zero any way.
407 * mon.c (mon_print_info): If possible, print the system cycle
408 performance. This is an indication of the number of instructions
411 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
413 * The code to allow an event queue to be updated during a signal

436 (event_queue_init): Start the event queue out with processing
438 (event_queue_tick): Check that processing isn't still being
441 * gen-idecode.c (print_run_until_stop_body): Call
442 event_queue_process_events to clear possibly pending events before
443 starting a simulation run. Re-arange main loop so that simulator
444 is correctly restarted when an event halts the simulation.

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

470 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
471 to be initialized independant of the rest of the simulation
472 initalization. Otherwize a trace option explictly set from gdb
473 could be overridden by hw_trace.
475 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
477 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
478 debug.c. It could be much simpler.
480 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

493 media. If no file image is specified, use the next one in the
495 (hw_disk_init_address): Change the file property so that it is a
496 string array - use the first entry for the initial file image.
498 * tree.c (print_string_aray_property): New function - print a
500 (print_properties): Adjust.

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

523 then generating corresponding definitions.
525 * gen-icache.c (print_icache_struct): If there is no cache, do not
526 output expressions in idecode.h file.

535 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
537 * The code that put values in and extracted values from the cache
538 was too compilicated. The cache table did not allow values to be
539 computed from cache entries. #defines could only be used when a
540 cache was present, remove the restriction.
542 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
543 scratch variable is defined when a cache entry is beinf
544 filled. Change the definition of a COMPUTE variable to be defined
545 when the cache entry is being used.
546 * gen-icache.c: Update.
548 * ld-cache.h, ld-cache.c: Change field names so that their meaning
549 is more obvious. old_name->field_name, new_name->derived_name.
550 * gen-icache.c: Update
552 * gen-icache.h, gen-icache.c (print_icache_body): Make the three

555 * gen-icache.c (print_icache_extraction): Ditto.
557 * gen-semantics.c (print_c_semantic): Update use.
558 * gen-idecode.c (print_jump_insn): Update use.

2103 * configure.in: Adjust filter flag so that default includes 32bit
