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

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

355 here. Update to new format.

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

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

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

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

454 * gen-semantics.c (print_c_semantic): Update use.
455 * gen-idecode.c (print_jump_insn): Update use.

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

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

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

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

522 hw_memory_instance_release): Handle multi-cell memory devices.

1836 * configure.in (icache): Extend icache flag to include an insn

1934 * igen.c: Add option (-C) to generate semantics in the instruction
1937 * configure.in (--enable-sim-icache): Accept an option list such
1938 as 1024,define. Add a new choice to the list - semantic - which

1944 * configure.in: New option --enable-sim-line-nr (default enabled).

1999 * Makefile.in (filter.o): Adjust
2000 * configure.in: Adjust filter flag so that default includes 32bit
