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

203 * device.c (device_find_ihandle_runtime_property): Update.
204 (device_add_ihandle_runtime_property): Update.

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

280 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
282 * When performance monitoring is disabled, it is still possible to
283 determine the simulation speed by looking at the number of elapsed
284 ticks recorded by the event queue.
286 * psim.c (psim_write_register, psim_read_register): Force the cpu
287 to zero when it is either of `-1' or `nr_cpus'. In both cases the
288 next cpu would be zero any way.
290 * mon.c (mon_print_info): If possible, print the system cycle
291 performance. This is an indication of the number of instructions
294 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
296 * The code to allow an event queue to be updated during a signal
297 was missing. For main.c, a cntrl-c simulation termination wasn't
300 * The simulation would not correctly restart if an event requested
301 that the simulation be halted.
303 * psim.c (psim_options): Add hack to -i option to optionally
304 include a level vis -i2.
305 (psim_usage): Document.

318 so that it is tolerant of halts.
319 (event_queue_init): Start the event queue out with processing
321 (event_queue_tick): Check that processing isn't still being
324 * gen-idecode.c (print_run_until_stop_body): Call
325 event_queue_process_events to clear possibly pending events before
326 starting a simulation run. Re-arange main loop so that simulator
327 is correctly restarted when an event halts the simulation.

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

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

398 as RA_is_0. If possible generate the result of the expression so
399 that the compiler gets a better chance of eliminating dead

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

406 then generating corresponding definitions.
408 * gen-icache.c (print_icache_struct): If there is no cache, do not

418 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
420 * The code that put values in and extracted values from the cache
421 was too compilicated. The cache table did not allow values to be
422 computed from cache entries. #defines could only be used when a
423 cache was present, remove the restriction.
425 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
426 scratch variable is defined when a cache entry is beinf
427 filled. Change the definition of a COMPUTE variable to be defined
428 when the cache entry is being used.
429 * gen-icache.c: Update.
431 * ld-cache.h, ld-cache.c: Change field names so that their meaning
432 is more obvious. old_name->field_name, new_name->derived_name.
433 * gen-icache.c: Update
435 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
436 different types of cache code - put into cache, extract from
437 cache, no cache - an explicit argument to print_icache_body.
438 * gen-icache.c (print_icache_extraction): Ditto.
440 * gen-semantics.c (print_c_semantic): Update use.
441 * gen-idecode.c (print_jump_insn): Update use.
442 * gen-icache.c (print_icache_function): Update use.
444 * igen.c (main): Change 'R' option so that it does not force the
447 * configure.in (enable-sim-icache): Clarify description. Make
448 #define one of the defaults regardless of the cache. Probably
449 should revamp and add a separate option.

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

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

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

508 hw_memory_instance_release): Handle multi-cell memory devices.

1728 * std-config.h (SEMANTICS_INLINE): By default, mask out the
1729 inlining of semantic functions from DEFAULT_INLINE. Almost all
1730 configurations call the semantic code via a pointer so there is

1761 always update the cache_entries semantic and address fields.

1817 option directly into the device tree. Was using atol() which is
1818 dangerously non portable.
1820 Mon Jul 22 22:17:08 1996 Andrew Cagney <cagney@highland.com.au>
1822 * configure.in (icache): Extend icache flag to include an insn

1861 * psim.c (run_until_stop): Delete the old run_until_stop function

1920 * igen.c: Add option (-C) to generate semantics in the instruction
1923 * configure.in (--enable-sim-icache): Accept an option list such
1924 as 1024,define. Add a new choice to the list - semantic - which
1925 will cause igen to generate instruction decode functions that

1930 * configure.in: New option --enable-sim-line-nr (default enabled).

1985 * Makefile.in (filter.o): Adjust
1986 * configure.in: Adjust filter flag so that default includes 32bit
