767 are simply renaming functions, to permit use of XCONCAT2 in both
768 the macro name and the arguments in a use of such a definition.
770 2000-11-15 Jim Blandy <jimb@redhat.com>
772 * sim_calls.c: Doc fix.
773 (sim_fetch_register, sim_store_register): Call

808 1999-05-08 Felix Lee <flee@cygnus.com>
810 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
811 * configure: Regenerated to track ../common/aclocal.m4 changes.
813 1999-04-02 Keith Seitz <keiths@cygnus.com>

831 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
833 Make the simulator compatible with the MPC750. It would be nicer
834 to make this a real multi-sim, but that's more work than we have
836 * emul_generic.c (emul_add_tree_options): Only require strict
837 alignment if it was explicitly requested at configuration time.
838 Don't make it the default for little-endian machines.
839 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,

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

863 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

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

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

1016 mask extracting shift amount. Correctly condition for setting XER
1018 (ldhau): From Johannes Reisinger, update rA after load.
1020 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
1022 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,
1024 * words.h: __int64 instead of long long for MSVC.

1329 determine the simulation speed by looking at the number of elapsed
1330 ticks recorded by the event queue.
1332 * psim.c (psim_write_register, psim_read_register): Force the cpu
1333 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1334 next cpu would be zero any way.
1336 * mon.c (mon_print_info): If possible, print the system cycle
1337 performance. This is an indication of the number of instructions
1340 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1342 * The code to allow an event queue to be updated during a signal
1343 was missing. For main.c, a cntrl-c simulation termination wasn't
1346 * The simulation would not correctly restart if an event requested
1347 that the simulation be halted.
1349 * psim.c (psim_options): Add hack to -i option to optionally
1350 include a level vis -i2.
1351 (psim_usage): Document.

1370 * gen-idecode.c (print_run_until_stop_body): Call
1371 event_queue_process_events to clear possibly pending events before
1372 starting a simulation run. Re-arange main loop so that simulator
1373 is correctly restarted when an event halts the simulation.

1397 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1399 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1400 to be initialized independant of the rest of the simulation
1401 initalization. Otherwize a trace option explictly set from gdb
1402 could be overridden by hw_trace.
1404 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1406 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1407 debug.c. It could be much simpler.
1409 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1425 string array - use the first entry for the initial file image.
1427 * tree.c (print_string_aray_property): New function - print a
1429 (print_properties): Adjust.

1448 * gen-icache.c (print_icache_extraction): For a cache entry of
1449 the form <name>_is_<const> where it is a boolean field, generate
1450 the result of the expression instead of the expression its self.

1452 then generating corresponding definitions.
1454 * gen-icache.c (print_icache_struct): If there is no cache, do not
1455 output expressions in idecode.h file.
1457 * gen-icache.c (print_icache_body): Output them here.
1459 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1464 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1466 * The code that put values in and extracted values from the cache
1467 was too compilicated. The cache table did not allow values to be
1468 computed from cache entries. #defines could only be used when a
1469 cache was present, remove the restriction.
1471 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1472 scratch variable is defined when a cache entry is beinf
1473 filled. Change the definition of a COMPUTE variable to be defined
1474 when the cache entry is being used.
1475 * gen-icache.c: Update.
1477 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1478 is more obvious. old_name->field_name, new_name->derived_name.
1479 * gen-icache.c: Update
1481 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1482 different types of cache code - put into cache, extract from
1483 cache, no cache - an explicit argument to print_icache_body.
1484 * gen-icache.c (print_icache_extraction): Ditto.
1486 * gen-semantics.c (print_c_semantic): Update use.
1487 * gen-idecode.c (print_jump_insn): Update use.
1488 * gen-icache.c (print_icache_function): Update use.
1490 * igen.c (main): Change 'R' option so that it does not force the
1493 * configure.in (enable-sim-icache): Clarify description. Make
1494 #define one of the defaults regardless of the cache. Probably
1495 should revamp and add a separate option.
1497 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1499 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1510 device after it was deleted. Instead add and remove cap's from the
1511 cap db as they are created and deleted. This ensuring that a
1512 capibility is only used during the lifetime of the corresponding
1515 * cap.h, cap.c: Correct cap type - was signed32 should be
1518 * cap.c (cap_add, cap_remove): New methods for cap object that
1519 allow the explicit addition and removal of internal objects that
1520 the cap knows about.
1522 * cap.c (cap_init): Rewrite. Verify that the only objects
1523 remaining in the cap data base are those that were entered first.
1524 Thse objects will be the permenant ones.
1525 * device.c (device_init_address): Remember to initialize the cap
1528 * device.c (device_create_instance_from): Explicitly add device
1529 instances to the cap database. Simplify create code.
