55
56 * Many of the ppc-opcode-* files are identical baring the type of
57 lookup table. Instead of having multiple tables, igen can do this
58 via an additional option.
59

101
102 * Property create/initialization still wasn't correctly ordered.
103 Should be delaying everything related to ihandle creation until
104 after the rest of the tree has been established.
105
106 * device.c (device_find_ihandle_runtime_property): Update.
107 (device_add_ihandle_runtime_property): Update.
108
109 * tree.c (parse_ihandle_property): Delay lookup of the device to
110 be opened until the ihandle initialization phase.
111 * tree.c (print_properties): Update.
112
113Wed Feb 5 10:56:27 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
114
115 * gen-icache.c (print_icache_extraction): Add a reason parameter.
116 Augment each extracted field with a comment citing the codes
117 origin. Should simplify tracking down incorrect cache
118 extractions.
119
120Tue Feb 4 17:44:51 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
121

123 works for normal and boolean table entries.
124
125 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
126 valid. Handle this just like *_{read,write}_register now handles

139 (psim_max_iterations_exceeded): New function, abort simulation if
140 max iterations exceeded.
141
142 * gen-idecode.c: Re-work the table lookup code so that it assumes
143 that the entry is a leaf by default. Simplify the boolean table
144 entry code so that it involves a mask + test instead of shift +
145 shift + mask + test.
146
147 * gen-idecode.c: Correct generated igen body so that it no drops
148 or doubles clock interrupts.

MM		 174Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
175
176 * igen wasn't aborting if the opcode table contained no valid
177 fields.
178
179 * misc.c (name2i): Possibly abort if an invalid name is
180 encountered.
181 * ld-decode.c: Abort if the table type isn't found.
182
183Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
184
185 * When performance monitoring is disabled, it is still possible to
186 determine the simulation speed by looking at the number of elapsed
187 ticks recorded by the event queue.
188
189 * psim.c (psim_write_register, psim_read_register): Force the cpu
190 to zero when it is either of `-1' or `nr_cpus'. In both cases the
191 next cpu would be zero any way.
192
193 * mon.c (mon_print_info): If possible, print the system cycle
194 performance. This is an indication of the number of instructions
195 per second.
196
197Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
198
199 * The code to allow an event queue to be updated during a signal
200 was missing. For main.c, a cntrl-c simulation termination wasn't
201 handled cleanly.
202
203 * The simulation would not correctly restart if an event requested
204 that the simulation be halted.
205
206 * psim.c (psim_options): Add hack to -i option to optionally
207 include a level vis -i2.
208 (psim_usage): Document.
209
210 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
211 cntrl-c occures schedule an event to halt the simulation.
212 (main): Catch CNTRL-C signals with the function cntrl_c.
213
214 * events.c (event_queue_process): Mask interrupts while
215 manipulating the async event queue.
216 (event_queue_init): Ditto.
217 (event_queue_schedule_after_signal): Ditto.
218
219 * events.c (event_queue_process): Mark the event queue as being in
220 the processing state when processing has started. Adjust code
221 so that it is tolerant of halts.
222 (event_queue_init): Start the event queue out with processing
223 false.
224 (event_queue_tick): Check that processing isn't still being
225 performed.
226
227 * gen-idecode.c (print_run_until_stop_body): Call
228 event_queue_process_events to clear possibly pending events before
229 starting a simulation run. Re-arange main loop so that simulator
230 is correctly restarted when an event halts the simulation.
231
232 * psim.c (psim_halt): Handle an event halting the simulation.
233 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
234 reworked idecode.
235
236Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
237
238 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
239 RA. Based on instruction frequency stats, expand additional
240 instructions.
241 * ppc-instructions: Change all `RA == 0' to RA_is_0.
242
243 * ppc-opcode-stupid: Move all but the basic table in -complex into
244 here. Update to new format.
245
246 * Makefile.in (tmp-defines): New target. Force defines.h to always
247 be built. Hence get ppc-opcode-goto to build.
248
249Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
250
251 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
252 Implement.
253
5c04f4f7
MM		 254Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
255
256 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
257 to be initialized independant of the rest of the simulation
258 initalization. Otherwize a trace option explictly set from gdb
259 could be overridden by hw_trace.
260
261 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
262
263 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
264 debug.c. It could be much simpler.
265
266Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
267
268 * Some devices support removable media. Add hooks to the disk
269 device so that it supports this.

276 (device_init_runtime_properties): Update.
277
278 * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
279 media. If no file image is specified, use the next one in the
280 image property list.
281 (hw_disk_init_address): Change the file property so that it is a
282 string array - use the first entry for the initial file image.
283
284 * tree.c (print_string_aray_property): New function - print a
285 string array.
286 (print_properties): Adjust.
287 (print_string): Write a string, handling double quotes.
288
289 * device.h: Define an ioctl to `change-media' with an optional new
290 media image.
291
292 * hw_disk.c: Allow floppy disk devices to be specified.
293
294 * psim.c (psim_command): New function, parse more complex psim
295 commands such as "change-media" and "trace".

297
298Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
299
300 * For expressions like (RA == 0) that are entered in to the cache
301 as RA_is_0. If possible generate the result of the expression so
302 that the compiler gets a better chance of eliminating dead
303 branches.
304
305 * gen-icache.c (print_icache_extraction): For a cache entry of
306 the form <name>_is_<const> where it is a boolean field, generate
307 the result of the expression instead of the expression its self.
308 (print_icache_body): Remove code that was looking for *_is_0 and
309 then generating corresponding definitions.
310
311 * gen-icache.c (print_icache_struct): If there is no cache, do not
312 output expressions in idecode.h file.
313
314 * gen-icache.c (print_icache_body): Output them here.
315
316 * ppc-opcode-complex: Clarify constant values for SPR==LR register
317 expansion.
318
319 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
320
321Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
322
323 * The code that put values in and extracted values from the cache
324 was too compilicated. The cache table did not allow values to be
325 computed from cache entries. #defines could only be used when a
326 cache was present, remove the restriction.
327
328 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
329 scratch variable is defined when a cache entry is beinf
330 filled. Change the definition of a COMPUTE variable to be defined
331 when the cache entry is being used.
332 * gen-icache.c: Update.
333
334 * ld-cache.h, ld-cache.c: Change field names so that their meaning
335 is more obvious. old_name->field_name, new_name->derived_name.
336 * gen-icache.c: Update
337
338 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
339 different types of cache code - put into cache, extract from
340 cache, no cache - an explicit argument to print_icache_body.
341 * gen-icache.c (print_icache_extraction): Ditto.
342
343 * gen-semantics.c (print_c_semantic): Update use.
344 * gen-idecode.c (print_jump_insn): Update use.
345 * gen-icache.c (print_icache_function): Update use.
346
347 * igen.c (main): Change 'R' option so that it does not force the
348 cache.
349
350 * configure.in (enable-sim-icache): Clarify description. Make
351 #define one of the defaults regardless of the cache. Probably
352 should revamp and add a separate option.
353
354Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
355
356 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

362 partition selection is supported.
363
364Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
365
366 * The cap object was retaining a reference to the instance of a
367 device after it was deleted. Instead add and remove cap's from the
368 cap db as they are created and deleted. This ensuring that a
369 capibility is only used during the lifetime of the corresponding
370 object.
371
372 * cap.h, cap.c: Correct cap type - was signed32 should be
373 signed_cell.
374
375 * cap.c (cap_add, cap_remove): New methods for cap object that
376 allow the explicit addition and removal of internal objects that
377 the cap knows about.
378
379 * cap.c (cap_init): Rewrite. Verify that the only objects
380 remaining in the cap data base are those that were entered first.
381 Thse objects will be the permenant ones.
382 * device.c (device_init_address): Remember to initialize the cap
383 database.
384
385 * device.c (device_create_instance_from): Explicitly add device
386 instances to the cap database. Simplify create code.

401 (split_property_specifier): Ditto.
402
403Sun Jan 19 15:28:23 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
404
405 * The memory "claim" and "release" methods take an address and
406 size as arguments. These may be multi cell values. Initially fix
407 the memory code so that they check/detect this. Leave the
408 adjustment of any clients to later.
409
410 * hw_memory.c (hw_memory_instance_claim,
411 hw_memory_instance_release): Handle multi-cell memory devices.
412
413 * hw_memory.c (hw_memory_instance_claim): Be tolerant towards the
414 release of memory regions that were not claimed.
415
416Fri Jan 17 12:01:07 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
417
418 * device.h, device.c (device_instance_call_method): Correct return
419 type - can return either 0 or -1, hence should be a signed type.
420 * device_table.h: Ditto.
421
422 * hw_memory.c (hw_memory_instance_claim,
423 hw_memory_instance_release): Update.

426
427Fri Jan 17 11:50:13 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
428
429 * emul_chirp.c (chirp_emul_claim): Implement using the "claim"
430 method belonging to "/chosen/memory".
431 (chirm_emul_release): Ditto.
432
433 * Makefile.in (LIB_INLINE_SRC): Remove emul_* from list of files
434 that are inlined. These modules are called via a table and are
435 not made inline.
436
437 * hw_init.c (update_for_binary_section): Fix failure to allocate
438 memory used by the binary in real-mode executions. If "claim"
439 property is present, allocate memory from the "/chosen/memory"
440 device.
441
442 * emul_chirp.c (emul_chirp_create): Specify that memory should be
443 claimed when loading a real image.

452
453 * vm.h (vm_data_map_read_buffer, vm_data_map_write_buffer): Add
454 optional PROCESSOR & CIA args so that this routine also abort an
455 access.
456
457 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N): For a
458 miss-aligned access when a transfer fails abort.
459
460 * emul_bugapi.c (emul_bugapi_do_write): Use emul_read_buffer

1630
1631 * std-config.h (SEMANTICS_INLINE): By default, mask out the
1632 inlining of semantic functions from DEFAULT_INLINE. Almost all

1664 always update the cache_entries semantic and address fields.
1665

1683 same as cpu.[hc].
1684
1685 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
1686 name for a lable and then branch to it.
1687
1688 * ppc-instructions (convert_to_integer, Floating Round to
1689 Single-Precision, Floating Convert from Integer Doubleword): Use
1690 LABEL and GOTO instead of the recently added switch statements.

1716
1717Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
1718

1760
1761 * std-config.h: Change psim.c so that it isn't inlined (as this is
1762 no longer needed).
1763
1764 * psim.c (run_until_stop): Delete the old run_until_stop function
1765 instead calling the idecode_run and idecode_run_until_stop
1766 functions that gen-idecode.c is now creating.

1800
1801 * gen-idecode.c (print_jump_until_stop_body): New function and
1802 idecode generation option. Instead of generating and calling

1816 testing jumping idecodes.
1817
