775 are simply renaming functions, to permit use of XCONCAT2 in both
776 the macro name and the arguments in a use of such a definition.
778 2000-11-15 Jim Blandy <jimb@redhat.com>
780 * sim_calls.c: Doc fix.
781 (sim_fetch_register, sim_store_register): Call

816 1999-05-08 Felix Lee <flee@cygnus.com>
818 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
819 * configure: Regenerated to track ../common/aclocal.m4 changes.
821 1999-04-02 Keith Seitz <keiths@cygnus.com>

839 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
841 Make the simulator compatible with the MPC750. It would be nicer
842 to make this a real multi-sim, but that's more work than we have
844 * emul_generic.c (emul_add_tree_options): Only require strict
845 alignment if it was explicitly requested at configuration time.
846 Don't make it the default for little-endian machines.
847 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,

849 THRM2, THRM3): Plop in the MPC750 SPR registers.
850 (DABR): This is weird. This was HID5, but the PPC spec says this
851 should be DABR; why did some random processor use it for something
852 else? The HID5 entry dates back to the original checkin of the
853 simulator code in 1995, so remove it.
854 * sim_calls.c (register_names): Delete this; since the user can
855 now change GDB's list of register names dynamically, we can't
856 pretend there's a static mapping here.
857 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
858 function to get the register name. That ought to be accurate.
859 However, we're changing a compile-time dependency (using the
860 REGISTER_NAMES macro) into a link- and run-time dependency
861 (calling REGISTER_NAME, which happens to be a function call on the
864 1999-01-22 Jim Lemke <jlemke@cygnus.com>

871 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

891 fractional type, so that quiet NaN's aren't treated like
894 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
896 * table.c (table_open): For cygwin hosts, we need to use the
897 return value from the read routine as the number of bytes to
898 process. This apparently is due to text-mode vs binary-mode. If
899 the mounts are done text-mode, then the size returnedby fstat()
900 may be different than the number of bytes "read" in text mode.
902 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
904 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

921 * configure: Regenerate.
922 * emul_{netbsd,unix}.c (toplevel): No longer try to include
923 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
925 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
927 * Makefile.in: The run target depended on a target psim$(EXEEXT),
928 but there was no such target, only plain psim. So I changed the
929 run target to depend on psim.
931 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
933 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
934 now defined in ../common/aclocal.m4, and the double definition causes
935 problems with AC_SUBST of EXEEXT.

1024 mask extracting shift amount. Correctly condition for setting XER
1026 (ldhau): From Johannes Reisinger, update rA after load.
1028 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
1030 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,
1032 * words.h: __int64 instead of long long for MSVC.

1299 or doubles clock interrupts.
1302 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1304 * Makefile.in (BUILT_SRC_WO_CONFIG): Change targ-vals.* to

1337 determine the simulation speed by looking at the number of elapsed
1338 ticks recorded by the event queue.
1340 * psim.c (psim_write_register, psim_read_register): Force the cpu
1341 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1342 next cpu would be zero any way.
1344 * mon.c (mon_print_info): If possible, print the system cycle
1345 performance. This is an indication of the number of instructions
1348 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1350 * The code to allow an event queue to be updated during a signal
1351 was missing. For main.c, a cntrl-c simulation termination wasn't
1354 * The simulation would not correctly restart if an event requested
1355 that the simulation be halted.
1357 * psim.c (psim_options): Add hack to -i option to optionally
1358 include a level vis -i2.
1359 (psim_usage): Document.
1361 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

1375 (event_queue_tick): Check that processing isn't still being
1378 * gen-idecode.c (print_run_until_stop_body): Call
1379 event_queue_process_events to clear possibly pending events before
1380 starting a simulation run. Re-arange main loop so that simulator
1381 is correctly restarted when an event halts the simulation.
1383 * psim.c (psim_halt): Handle an event halting the simulation.
1384 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1387 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1389 * ppc-opcode-complex: Correct typo - was expanding ORA instead of

1405 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1407 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1408 to be initialized independant of the rest of the simulation
1409 initalization. Otherwize a trace option explictly set from gdb
1410 could be overridden by hw_trace.
1412 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1414 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1415 debug.c. It could be much simpler.
1417 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1431 image property list.
1432 (hw_disk_init_address): Change the file property so that it is a
1433 string array - use the first entry for the initial file image.
1435 * tree.c (print_string_aray_property): New function - print a
1437 (print_properties): Adjust.

1452 as RA_is_0. If possible generate the result of the expression so
1453 that the compiler gets a better chance of eliminating dead
1456 * gen-icache.c (print_icache_extraction): For a cache entry of
1457 the form <name>_is_<const> where it is a boolean field, generate
1458 the result of the expression instead of the expression its self.
1459 (print_icache_body): Remove code that was looking for *_is_0 and
1460 then generating corresponding definitions.
1462 * gen-icache.c (print_icache_struct): If there is no cache, do not
1463 output expressions in idecode.h file.
1465 * gen-icache.c (print_icache_body): Output them here.
1467 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1470 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
1472 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1474 * The code that put values in and extracted values from the cache
1475 was too compilicated. The cache table did not allow values to be
1476 computed from cache entries. #defines could only be used when a
1477 cache was present, remove the restriction.
1479 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1480 scratch variable is defined when a cache entry is beinf
1481 filled. Change the definition of a COMPUTE variable to be defined
1482 when the cache entry is being used.
1483 * gen-icache.c: Update.
1485 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1486 is more obvious. old_name->field_name, new_name->derived_name.
1487 * gen-icache.c: Update
1489 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1490 different types of cache code - put into cache, extract from
1491 cache, no cache - an explicit argument to print_icache_body.
1492 * gen-icache.c (print_icache_extraction): Ditto.
1494 * gen-semantics.c (print_c_semantic): Update use.
1495 * gen-idecode.c (print_jump_insn): Update use.
1496 * gen-icache.c (print_icache_function): Update use.
1498 * igen.c (main): Change 'R' option so that it does not force the
1501 * configure.in (enable-sim-icache): Clarify description. Make
1502 #define one of the defaults regardless of the cache. Probably
1503 should revamp and add a separate option.
1505 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1507 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1518 device after it was deleted. Instead add and remove cap's from the
1519 cap db as they are created and deleted. This ensuring that a
1520 capibility is only used during the lifetime of the corresponding
1523 * cap.h, cap.c: Correct cap type - was signed32 should be
1526 * cap.c (cap_add, cap_remove): New methods for cap object that
1527 allow the explicit addition and removal of internal objects that
1528 the cap knows about.
1530 * cap.c (cap_init): Rewrite. Verify that the only objects
1531 remaining in the cap data base are those that were entered first.
1532 Thse objects will be the permenant ones.
1533 * device.c (device_init_address): Remember to initialize the cap
1536 * device.c (device_create_instance_from): Explicitly add device
1537 instances to the cap database. Simplify create code.

1573 * hw_memory.c (hw_memory_instance_claim,
1574 hw_memory_instance_release): Update.
