298 * Property create/initialization still wasn't correctly ordered.
299 Should be delaying everything related to ihandle creation until

302 * device.c (device_find_ihandle_runtime_property): Update.
303 (device_add_ihandle_runtime_property): Update.

344 or doubles clock interrupts.
347 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

379 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
381 * When performance monitoring is disabled, it is still possible to
382 determine the simulation speed by looking at the number of elapsed
383 ticks recorded by the event queue.
385 * psim.c (psim_write_register, psim_read_register): Force the cpu
386 to zero when it is either of `-1' or `nr_cpus'. In both cases the
387 next cpu would be zero any way.
389 * mon.c (mon_print_info): If possible, print the system cycle
390 performance. This is an indication of the number of instructions
393 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
395 * The code to allow an event queue to be updated during a signal
396 was missing. For main.c, a cntrl-c simulation termination wasn't
399 * The simulation would not correctly restart if an event requested
400 that the simulation be halted.
402 * psim.c (psim_options): Add hack to -i option to optionally
403 include a level vis -i2.
404 (psim_usage): Document.

417 so that it is tolerant of halts.
418 (event_queue_init): Start the event queue out with processing
420 (event_queue_tick): Check that processing isn't still being
423 * gen-idecode.c (print_run_until_stop_body): Call
424 event_queue_process_events to clear possibly pending events before
425 starting a simulation run. Re-arange main loop so that simulator
426 is correctly restarted when an event halts the simulation.
428 * psim.c (psim_halt): Handle an event halting the simulation.
429 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
432 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

437 * ppc-instructions: Change all `RA == 0' to RA_is_0.
439 * ppc-opcode-stupid: Move all but the basic table in -complex into
440 here. Update to new format.

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

469 properties containing an array of strings.

475 media. If no file image is specified, use the next one in the
477 (hw_disk_init_address): Change the file property so that it is a
478 string array - use the first entry for the initial file image.
480 * tree.c (print_string_aray_property): New function - print a
482 (print_properties): Adjust.
483 (print_string): Write a string, handling double quotes.

497 as RA_is_0. If possible generate the result of the expression so
498 that the compiler gets a better chance of eliminating dead
501 * gen-icache.c (print_icache_extraction): For a cache entry of
502 the form <name>_is_<const> where it is a boolean field, generate
503 the result of the expression instead of the expression its self.
504 (print_icache_body): Remove code that was looking for *_is_0 and
505 then generating corresponding definitions.
507 * gen-icache.c (print_icache_struct): If there is no cache, do not
508 output expressions in idecode.h file.
510 * gen-icache.c (print_icache_body): Output them here.

517 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
519 * The code that put values in and extracted values from the cache
520 was too compilicated. The cache table did not allow values to be
521 computed from cache entries. #defines could only be used when a
522 cache was present, remove the restriction.
524 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
525 scratch variable is defined when a cache entry is beinf
526 filled. Change the definition of a COMPUTE variable to be defined
527 when the cache entry is being used.
528 * gen-icache.c: Update.
530 * ld-cache.h, ld-cache.c: Change field names so that their meaning
531 is more obvious. old_name->field_name, new_name->derived_name.
532 * gen-icache.c: Update
534 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
535 different types of cache code - put into cache, extract from
536 cache, no cache - an explicit argument to print_icache_body.
537 * gen-icache.c (print_icache_extraction): Ditto.
539 * gen-semantics.c (print_c_semantic): Update use.
540 * gen-idecode.c (print_jump_insn): Update use.
541 * gen-icache.c (print_icache_function): Update use.
543 * igen.c (main): Change 'R' option so that it does not force the
546 * configure.in (enable-sim-icache): Clarify description. Make
547 #define one of the defaults regardless of the cache. Probably
548 should revamp and add a separate option.
550 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
552 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
554 (pk_disklabel_create_instance): Partition 1..4 are valid - not
556 (is_iso9660): New function, verify a CD9660 File system.

558 partition selection is supported.
560 Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

2085 * configure.in: Adjust filter flag so that default includes 32bit
