274 (psim_max_iterations_exceeded): New function, abort simulation if
275 max iterations exceeded.
276
277 * gen-idecode.c: Re-work the table lookup code so that it assumes
278 that the entry is a leaf by default. Simplify the boolean table
279 entry code so that it involves a mask + test instead of shift +
280 shift + mask + test.
281
282 * gen-idecode.c: Correct generated igen body so that it no drops
283 or doubles clock interrupts.
284

MM		 309Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
310
311 * igen wasn't aborting if the opcode table contained no valid
312 fields.
313
314 * misc.c (name2i): Possibly abort if an invalid name is
315 encountered.
316 * ld-decode.c: Abort if the table type isn't found.
317
318Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
319
320 * When performance monitoring is disabled, it is still possible to
321 determine the simulation speed by looking at the number of elapsed
322 ticks recorded by the event queue.
323
324 * psim.c (psim_write_register, psim_read_register): Force the cpu
325 to zero when it is either of `-1' or `nr_cpus'. In both cases the
326 next cpu would be zero any way.
327
328 * mon.c (mon_print_info): If possible, print the system cycle
329 performance. This is an indication of the number of instructions
330 per second.
331
332Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
333
334 * The code to allow an event queue to be updated during a signal
335 was missing. For main.c, a cntrl-c simulation termination wasn't
336 handled cleanly.
337
338 * The simulation would not correctly restart if an event requested
339 that the simulation be halted.
340
341 * psim.c (psim_options): Add hack to -i option to optionally
342 include a level vis -i2.
343 (psim_usage): Document.
344
345 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

352 (event_queue_schedule_after_signal): Ditto.
353
354 * events.c (event_queue_process): Mark the event queue as being in
355 the processing state when processing has started. Adjust code
356 so that it is tolerant of halts.
357 (event_queue_init): Start the event queue out with processing
358 false.
359 (event_queue_tick): Check that processing isn't still being
360 performed.
361
362 * gen-idecode.c (print_run_until_stop_body): Call
363 event_queue_process_events to clear possibly pending events before
364 starting a simulation run. Re-arange main loop so that simulator
365 is correctly restarted when an event halts the simulation.

368 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
369 reworked idecode.
370
371Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
372
373 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
374 RA. Based on instruction frequency stats, expand additional
375 instructions.
376 * ppc-instructions: Change all `RA == 0' to RA_is_0.
377
378 * ppc-opcode-stupid: Move all but the basic table in -complex into
379 here. Update to new format.
380
381 * Makefile.in (tmp-defines): New target. Force defines.h to always
382 be built. Hence get ppc-opcode-goto to build.
383
384Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
385

MM		 389Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
390
391 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
392 to be initialized independant of the rest of the simulation
393 initalization. Otherwize a trace option explictly set from gdb
394 could be overridden by hw_trace.
395
396 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
397
398 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
399 debug.c. It could be much simpler.
400
401Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
402
403 * Some devices support removable media. Add hooks to the disk
404 device so that it supports this.
405
406 * device.c (device_add_string_array_property,
407 device_find_string_array_property): New functions, manipulate
408 properties containing an array of strings.

410 (device_init_static_properties): Update.
411 (device_init_runtime_properties): Update.
412
413 * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
414 media. If no file image is specified, use the next one in the
415 image property list.
416 (hw_disk_init_address): Change the file property so that it is a
417 string array - use the first entry for the initial file image.
418
419 * tree.c (print_string_aray_property): New function - print a
420 string array.
421 (print_properties): Adjust.
422 (print_string): Write a string, handling double quotes.
423
424 * device.h: Define an ioctl to `change-media' with an optional new
425 media image.
426
427 * hw_disk.c: Allow floppy disk devices to be specified.
428
429 * psim.c (psim_command): New function, parse more complex psim
430 commands such as "change-media" and "trace".

432
433Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
434
435 * For expressions like (RA == 0) that are entered in to the cache
436 as RA_is_0. If possible generate the result of the expression so
437 that the compiler gets a better chance of eliminating dead
438 branches.
439
440 * gen-icache.c (print_icache_extraction): For a cache entry of
441 the form <name>_is_<const> where it is a boolean field, generate
442 the result of the expression instead of the expression its self.
443 (print_icache_body): Remove code that was looking for *_is_0 and
444 then generating corresponding definitions.
445
446 * gen-icache.c (print_icache_struct): If there is no cache, do not
447 output expressions in idecode.h file.
448
449 * gen-icache.c (print_icache_body): Output them here.
450
451 * ppc-opcode-complex: Clarify constant values for SPR==LR register
452 expansion.
453
454 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
455
456Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
457
458 * The code that put values in and extracted values from the cache

1891
1892 * gen-idecode.c: Output the complete run_until_stop function
1893 instead of just the code to handle a single instruction issue.
1894 * : Have the generated idecode.c include inline.c (instead of psim.c).
1895
1896 * std-config.h: Change psim.c so that it isn't inlined (as this is
1897 no longer needed).
1898
1899 * psim.c (run_until_stop): Delete the old run_until_stop function
1900 instead calling the idecode_run and idecode_run_until_stop
1901 functions that gen-idecode.c is now creating.

1928 corresponding call to ITRACE so that it still matches.
1929
1930 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead

1935
1936 * gen-idecode.c (print_jump_until_stop_body): New function and
1937 idecode generation option. Instead of generating and calling

1967
1968 * configure.in: New option --enable-sim-line-nr (default enabled).
