771 are simply renaming functions, to permit use of XCONCAT2 in both
772 the macro name and the arguments in a use of such a definition.
774 2000-11-15 Jim Blandy <jimb@redhat.com>
776 * sim_calls.c: Doc fix.
777 (sim_fetch_register, sim_store_register): Call

812 1999-05-08 Felix Lee <flee@cygnus.com>
814 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.

817 1999-04-02 Keith Seitz <keiths@cygnus.com>

835 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
837 Make the simulator compatible with the MPC750. It would be nicer
838 to make this a real multi-sim, but that's more work than we have
840 * emul_generic.c (emul_add_tree_options): Only require strict
841 alignment if it was explicitly requested at configuration time.
842 Don't make it the default for little-endian machines.
843 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,

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

867 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

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

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

1024 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
1026 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,
1028 * words.h: __int64 instead of long long for MSVC.

1333 determine the simulation speed by looking at the number of elapsed
1334 ticks recorded by the event queue.
1336 * psim.c (psim_write_register, psim_read_register): Force the cpu
1337 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1338 next cpu would be zero any way.
1340 * mon.c (mon_print_info): If possible, print the system cycle
1341 performance. This is an indication of the number of instructions
1344 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1346 * The code to allow an event queue to be updated during a signal
1347 was missing. For main.c, a cntrl-c simulation termination wasn't
1350 * The simulation would not correctly restart if an event requested
1351 that the simulation be halted.
1353 * psim.c (psim_options): Add hack to -i option to optionally
1354 include a level vis -i2.
1355 (psim_usage): Document.

1374 * gen-idecode.c (print_run_until_stop_body): Call
1375 event_queue_process_events to clear possibly pending events before
1376 starting a simulation run. Re-arange main loop so that simulator
1377 is correctly restarted when an event halts the simulation.
1379 * psim.c (psim_halt): Handle an event halting the simulation.
1380 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1383 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1385 * ppc-opcode-complex: Correct typo - was expanding ORA instead of

1403 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1404 to be initialized independant of the rest of the simulation
1405 initalization. Otherwize a trace option explictly set from gdb
1406 could be overridden by hw_trace.
1408 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1410 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1411 debug.c. It could be much simpler.
1413 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1429 string array - use the first entry for the initial file image.
1431 * tree.c (print_string_aray_property): New function - print a
1433 (print_properties): Adjust.

1452 * gen-icache.c (print_icache_extraction): For a cache entry of
1453 the form <name>_is_<const> where it is a boolean field, generate
1454 the result of the expression instead of the expression its self.
1455 (print_icache_body): Remove code that was looking for *_is_0 and
1456 then generating corresponding definitions.
1458 * gen-icache.c (print_icache_struct): If there is no cache, do not
1459 output expressions in idecode.h file.
1461 * gen-icache.c (print_icache_body): Output them here.
1463 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1468 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1470 * The code that put values in and extracted values from the cache
1471 was too compilicated. The cache table did not allow values to be
1472 computed from cache entries. #defines could only be used when a
1473 cache was present, remove the restriction.
1475 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1476 scratch variable is defined when a cache entry is beinf
1477 filled. Change the definition of a COMPUTE variable to be defined
1478 when the cache entry is being used.
1479 * gen-icache.c: Update.
1481 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1482 is more obvious. old_name->field_name, new_name->derived_name.
1483 * gen-icache.c: Update
1485 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1486 different types of cache code - put into cache, extract from
1487 cache, no cache - an explicit argument to print_icache_body.
1488 * gen-icache.c (print_icache_extraction): Ditto.
1490 * gen-semantics.c (print_c_semantic): Update use.
1491 * gen-idecode.c (print_jump_insn): Update use.
1492 * gen-icache.c (print_icache_function): Update use.
1494 * igen.c (main): Change 'R' option so that it does not force the
1497 * configure.in (enable-sim-icache): Clarify description. Make
1498 #define one of the defaults regardless of the cache. Probably
1499 should revamp and add a separate option.
1501 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1503 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1514 device after it was deleted. Instead add and remove cap's from the
1515 cap db as they are created and deleted. This ensuring that a
1516 capibility is only used during the lifetime of the corresponding
1519 * cap.h, cap.c: Correct cap type - was signed32 should be
1522 * cap.c (cap_add, cap_remove): New methods for cap object that
1523 allow the explicit addition and removal of internal objects that
1524 the cap knows about.
1526 * cap.c (cap_init): Rewrite. Verify that the only objects
1527 remaining in the cap data base are those that were entered first.
1528 Thse objects will be the permenant ones.
1529 * device.c (device_init_address): Remember to initialize the cap
1532 * device.c (device_create_instance_from): Explicitly add device
1533 instances to the cap database. Simplify create code.
