779 are simply renaming functions, to permit use of XCONCAT2 in both
780 the macro name and the arguments in a use of such a definition.
782 2000-11-15 Jim Blandy <jimb@redhat.com>
784 * sim_calls.c: Doc fix.
785 (sim_fetch_register, sim_store_register): Call

820 1999-05-08 Felix Lee <flee@cygnus.com>
822 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.

843 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
845 Make the simulator compatible with the MPC750. It would be nicer
846 to make this a real multi-sim, but that's more work than we have
848 * emul_generic.c (emul_add_tree_options): Only require strict
849 alignment if it was explicitly requested at configuration time.
850 Don't make it the default for little-endian machines.
851 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,

853 THRM2, THRM3): Plop in the MPC750 SPR registers.
854 (DABR): This is weird. This was HID5, but the PPC spec says this
855 should be DABR; why did some random processor use it for something
856 else? The HID5 entry dates back to the original checkin of the
857 simulator code in 1995, so remove it.
858 * sim_calls.c (register_names): Delete this; since the user can
859 now change GDB's list of register names dynamically, we can't
860 pretend there's a static mapping here.
861 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
862 function to get the register name. That ought to be accurate.
863 However, we're changing a compile-time dependency (using the
864 REGISTER_NAMES macro) into a link- and run-time dependency
865 (calling REGISTER_NAME, which happens to be a function call on the
868 1999-01-22 Jim Lemke <jlemke@cygnus.com>

875 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

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

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

1028 mask extracting shift amount. Correctly condition for setting XER
1030 (ldhau): From Johannes Reisinger, update rA after load.
1032 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
1034 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,
1036 * words.h: __int64 instead of long long for MSVC.

1341 determine the simulation speed by looking at the number of elapsed
1342 ticks recorded by the event queue.
1344 * psim.c (psim_write_register, psim_read_register): Force the cpu
1345 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1346 next cpu would be zero any way.
1348 * mon.c (mon_print_info): If possible, print the system cycle
1349 performance. This is an indication of the number of instructions
1352 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1354 * The code to allow an event queue to be updated during a signal
1355 was missing. For main.c, a cntrl-c simulation termination wasn't
1358 * The simulation would not correctly restart if an event requested
1359 that the simulation be halted.
1361 * psim.c (psim_options): Add hack to -i option to optionally
1362 include a level vis -i2.
1363 (psim_usage): Document.

1379 (event_queue_tick): Check that processing isn't still being
1382 * gen-idecode.c (print_run_until_stop_body): Call
1383 event_queue_process_events to clear possibly pending events before
1384 starting a simulation run. Re-arange main loop so that simulator
1385 is correctly restarted when an event halts the simulation.
1387 * psim.c (psim_halt): Handle an event halting the simulation.
1388 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1391 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1411 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1412 to be initialized independant of the rest of the simulation
1413 initalization. Otherwize a trace option explictly set from gdb
1414 could be overridden by hw_trace.
1416 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1418 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1419 debug.c. It could be much simpler.
1421 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1437 string array - use the first entry for the initial file image.
1439 * tree.c (print_string_aray_property): New function - print a

1460 * gen-icache.c (print_icache_extraction): For a cache entry of
1461 the form <name>_is_<const> where it is a boolean field, generate
1462 the result of the expression instead of the expression its self.

1464 then generating corresponding definitions.
1466 * gen-icache.c (print_icache_struct): If there is no cache, do not
1467 output expressions in idecode.h file.
1469 * gen-icache.c (print_icache_body): Output them here.
1471 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1476 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1478 * The code that put values in and extracted values from the cache
1479 was too compilicated. The cache table did not allow values to be
1480 computed from cache entries. #defines could only be used when a
1481 cache was present, remove the restriction.
1483 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1484 scratch variable is defined when a cache entry is beinf
1485 filled. Change the definition of a COMPUTE variable to be defined
1486 when the cache entry is being used.
1487 * gen-icache.c: Update.
1489 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1490 is more obvious. old_name->field_name, new_name->derived_name.
1491 * gen-icache.c: Update
1493 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1494 different types of cache code - put into cache, extract from
1495 cache, no cache - an explicit argument to print_icache_body.
1496 * gen-icache.c (print_icache_extraction): Ditto.
1498 * gen-semantics.c (print_c_semantic): Update use.
1499 * gen-idecode.c (print_jump_insn): Update use.
1500 * gen-icache.c (print_icache_function): Update use.
1502 * igen.c (main): Change 'R' option so that it does not force the
1505 * configure.in (enable-sim-icache): Clarify description. Make
1506 #define one of the defaults regardless of the cache. Probably
1507 should revamp and add a separate option.
1509 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1511 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1522 device after it was deleted. Instead add and remove cap's from the
1523 cap db as they are created and deleted. This ensuring that a
1524 capibility is only used during the lifetime of the corresponding
1527 * cap.h, cap.c: Correct cap type - was signed32 should be
1530 * cap.c (cap_add, cap_remove): New methods for cap object that
1531 allow the explicit addition and removal of internal objects that
1532 the cap knows about.
1534 * cap.c (cap_init): Rewrite. Verify that the only objects
1535 remaining in the cap data base are those that were entered first.
1536 Thse objects will be the permenant ones.
1537 * device.c (device_init_address): Remember to initialize the cap
1540 * device.c (device_create_instance_from): Explicitly add device
1541 instances to the cap database. Simplify create code.
