837 now change GDB's list of register names dynamically, we can't
838 pretend there's a static mapping here.
839 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
840 function to get the register name. That ought to be accurate.
841 However, we're changing a compile-time dependency (using the
842 REGISTER_NAMES macro) into a link- and run-time dependency
843 (calling REGISTER_NAME, which happens to be a function call on the
844 PPC).
845
8461999-01-22 Jim Lemke <jlemke@cygnus.com>
847

877
878 * table.c (table_open): For cygwin hosts, we need to use the
879 return value from the read routine as the number of bytes to
880 process. This apparently is due to text-mode vs binary-mode. If
881 the mounts are done text-mode, then the size returnedby fstat()
882 may be different than the number of bytes "read" in text mode.

1291
1292Wed Jan 29 12:32:41 1997 Michael Meissner <meissner@tiktok.cygnus.com>
1293
1294 * configure.in (sim_callback): If the gdb is post 4.16, configure
1295 callback support from the common directory.
1296 * configure: Regenerate.
1297

1308
1309 * igen wasn't aborting if the opcode table contained no valid
1310 fields.
1311
1312 * misc.c (name2i): Possibly abort if an invalid name is
1313 encountered.
1314 * ld-decode.c: Abort if the table type isn't found.
1315
1316Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1317
1318 * When performance monitoring is disabled, it is still possible to
1319 determine the simulation speed by looking at the number of elapsed
1320 ticks recorded by the event queue.
1321
1322 * psim.c (psim_write_register, psim_read_register): Force the cpu
1323 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1324 next cpu would be zero any way.
1325
1326 * mon.c (mon_print_info): If possible, print the system cycle
1327 performance. This is an indication of the number of instructions
1328 per second.
1329
1330Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1331
1332 * The code to allow an event queue to be updated during a signal
1333 was missing. For main.c, a cntrl-c simulation termination wasn't
1334 handled cleanly.
1335
1336 * The simulation would not correctly restart if an event requested
1337 that the simulation be halted.
1338
1339 * psim.c (psim_options): Add hack to -i option to optionally
1340 include a level vis -i2.
1341 (psim_usage): Document.
1342
1343 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
1344 cntrl-c occures schedule an event to halt the simulation.
1345 (main): Catch CNTRL-C signals with the function cntrl_c.
1346
1347 * events.c (event_queue_process): Mask interrupts while
1348 manipulating the async event queue.
1349 (event_queue_init): Ditto.
1350 (event_queue_schedule_after_signal): Ditto.
1351
1352 * events.c (event_queue_process): Mark the event queue as being in
1353 the processing state when processing has started. Adjust code
1354 so that it is tolerant of halts.
1355 (event_queue_init): Start the event queue out with processing
1356 false.
1357 (event_queue_tick): Check that processing isn't still being
1358 performed.
1359
1360 * gen-idecode.c (print_run_until_stop_body): Call
1361 event_queue_process_events to clear possibly pending events before
1362 starting a simulation run. Re-arange main loop so that simulator
1363 is correctly restarted when an event halts the simulation.
1364
1365 * psim.c (psim_halt): Handle an event halting the simulation.
1366 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1367 reworked idecode.
1368
1369Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1370
1371 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1372 RA. Based on instruction frequency stats, expand additional
1373 instructions.
1374 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1375
1376 * ppc-opcode-stupid: Move all but the basic table in -complex into
1377 here. Update to new format.
1378
1379 * Makefile.in (tmp-defines): New target. Force defines.h to always
1380 be built. Hence get ppc-opcode-goto to build.
1381
1382Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1383
1384 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1385 Implement.
1386
1387Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1388
1389 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1390 to be initialized independant of the rest of the simulation
1391 initalization. Otherwize a trace option explictly set from gdb
1392 could be overridden by hw_trace.
1393
1394 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1395
1396 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1397 debug.c. It could be much simpler.
1398
1399Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1400
1401 * Some devices support removable media. Add hooks to the disk
1402 device so that it supports this.

1413 image property list.
1414 (hw_disk_init_address): Change the file property so that it is a
1415 string array - use the first entry for the initial file image.
1416
1417 * tree.c (print_string_aray_property): New function - print a
1418 string array.
1419 (print_properties): Adjust.
1420 (print_string): Write a string, handling double quotes.

1426
1427 * psim.c (psim_command): New function, parse more complex psim
1428 commands such as "change-media" and "trace".

1430
1431Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1432
1433 * For expressions like (RA == 0) that are entered in to the cache
1434 as RA_is_0. If possible generate the result of the expression so
1435 that the compiler gets a better chance of eliminating dead
1436 branches.
1437
1438 * gen-icache.c (print_icache_extraction): For a cache entry of
1439 the form <name>_is_<const> where it is a boolean field, generate
1440 the result of the expression instead of the expression its self.
1441 (print_icache_body): Remove code that was looking for *_is_0 and
1442 then generating corresponding definitions.
1443
1444 * gen-icache.c (print_icache_struct): If there is no cache, do not
1445 output expressions in idecode.h file.
1446
1447 * gen-icache.c (print_icache_body): Output them here.
1448
1449 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1450 expansion.

1454Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1455
1456 * The code that put values in and extracted values from the cache
1457 was too compilicated. The cache table did not allow values to be
1458 computed from cache entries. #defines could only be used when a
1459 cache was present, remove the restriction.
1460
1461 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1462 scratch variable is defined when a cache entry is beinf
1463 filled. Change the definition of a COMPUTE variable to be defined
1464 when the cache entry is being used.
1465 * gen-icache.c: Update.
1466
1467 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1468 is more obvious. old_name->field_name, new_name->derived_name.
1469 * gen-icache.c: Update
1470
1471 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1472 different types of cache code - put into cache, extract from
1473 cache, no cache - an explicit argument to print_icache_body.
1474 * gen-icache.c (print_icache_extraction): Ditto.
1475
1476 * gen-semantics.c (print_c_semantic): Update use.
1477 * gen-idecode.c (print_jump_insn): Update use.
1478 * gen-icache.c (print_icache_function): Update use.
1479
1480 * igen.c (main): Change 'R' option so that it does not force the
1481 cache.
1482
1483 * configure.in (enable-sim-icache): Clarify description. Make
1484 #define one of the defaults regardless of the cache. Probably
1485 should revamp and add a separate option.
1486
1487Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1488

1497Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1498
1499 * The cap object was retaining a reference to the instance of a
1500 device after it was deleted. Instead add and remove cap's from the
1501 cap db as they are created and deleted. This ensuring that a
1502 capibility is only used during the lifetime of the corresponding
1503 object.
1504
1505 * cap.h, cap.c: Correct cap type - was signed32 should be
1506 signed_cell.
1507
1508 * cap.c (cap_add, cap_remove): New methods for cap object that
1509 allow the explicit addition and removal of internal objects that
1510 the cap knows about.
1511
1512 * cap.c (cap_init): Rewrite. Verify that the only objects
1513 remaining in the cap data base are those that were entered first.
1514 Thse objects will be the permenant ones.
1515 * device.c (device_init_address): Remember to initialize the cap
1516 database.

1537
1538 * The memory "claim" and "release" methods take an address and
1539 size as arguments. These may be multi cell values. Initially fix
1540 the memory code so that they check/detect this. Leave the
1541 adjustment of any clients to later.

2815 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2816 same as cpu.[hc].
2817
2818 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2819 name for a lable and then branch to it.
2820
2821 * ppc-instructions (convert_to_integer, Floating Round to
2822 Single-Precision, Floating Convert from Integer Doubleword): Use
2823 LABEL and GOTO instead of the recently added switch statements.

2849
2850Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
2851
2852 * psim.c (psim_options): Enter the argument to the memory size
2853 option directly into the device tree. Was using atol() which is

2893
2894 * std-config.h: Change psim.c so that it isn't inlined (as this is
2895 no longer needed).
2896
2897 * psim.c (run_until_stop): Delete the old run_until_stop function
2898 instead calling the idecode_run and idecode_run_until_stop
2899 functions that gen-idecode.c is now creating.

2965
2966 * configure.in: New option --enable-sim-line-nr (default enabled).
