10 * Makefile.in: The run target depended on a target psim$(EXEEXT),
11 but there was no such target, only plain psim. So I changed the

340 * device.c (device_find_ihandle_runtime_property): Update.
341 (device_add_ihandle_runtime_property): Update.

417 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
419 * When performance monitoring is disabled, it is still possible to
420 determine the simulation speed by looking at the number of elapsed
421 ticks recorded by the event queue.
423 * psim.c (psim_write_register, psim_read_register): Force the cpu
424 to zero when it is either of `-1' or `nr_cpus'. In both cases the
425 next cpu would be zero any way.
427 * mon.c (mon_print_info): If possible, print the system cycle
428 performance. This is an indication of the number of instructions
431 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
433 * The code to allow an event queue to be updated during a signal
434 was missing. For main.c, a cntrl-c simulation termination wasn't
437 * The simulation would not correctly restart if an event requested
438 that the simulation be halted.
440 * psim.c (psim_options): Add hack to -i option to optionally
441 include a level vis -i2.
442 (psim_usage): Document.

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

478 here. Update to new format.

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

507 properties containing an array of strings.

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

535 as RA_is_0. If possible generate the result of the expression so
536 that the compiler gets a better chance of eliminating dead
539 * gen-icache.c (print_icache_extraction): For a cache entry of
540 the form <name>_is_<const> where it is a boolean field, generate
541 the result of the expression instead of the expression its self.
542 (print_icache_body): Remove code that was looking for *_is_0 and
543 then generating corresponding definitions.
545 * gen-icache.c (print_icache_struct): If there is no cache, do not
546 output expressions in idecode.h file.
548 * gen-icache.c (print_icache_body): Output them here.
550 * ppc-opcode-complex: Clarify constant values for SPR==LR register
553 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
555 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
557 * The code that put values in and extracted values from the cache
558 was too compilicated. The cache table did not allow values to be
559 computed from cache entries. #defines could only be used when a
560 cache was present, remove the restriction.
562 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A

2123 * configure.in: Adjust filter flag so that default includes 32bit
