785 are simply renaming functions, to permit use of XCONCAT2 in both
786 the macro name and the arguments in a use of such a definition.
788 2000-11-15 Jim Blandy <jimb@redhat.com>
790 * sim_calls.c: Doc fix.
791 (sim_fetch_register, sim_store_register): Call

826 1999-05-08 Felix Lee <flee@cygnus.com>
828 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.

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

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

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

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

1034 mask extracting shift amount. Correctly condition for setting XER
1036 (ldhau): From Johannes Reisinger, update rA after load.
1038 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
1040 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,

1347 determine the simulation speed by looking at the number of elapsed
1348 ticks recorded by the event queue.
1350 * psim.c (psim_write_register, psim_read_register): Force the cpu
1351 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1352 next cpu would be zero any way.
1354 * mon.c (mon_print_info): If possible, print the system cycle
1355 performance. This is an indication of the number of instructions
1358 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1360 * The code to allow an event queue to be updated during a signal
1361 was missing. For main.c, a cntrl-c simulation termination wasn't
1364 * The simulation would not correctly restart if an event requested
1365 that the simulation be halted.
1367 * psim.c (psim_options): Add hack to -i option to optionally
1368 include a level vis -i2.
1369 (psim_usage): Document.

1388 * gen-idecode.c (print_run_until_stop_body): Call
1389 event_queue_process_events to clear possibly pending events before
1390 starting a simulation run. Re-arange main loop so that simulator
1391 is correctly restarted when an event halts the simulation.

1417 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1418 to be initialized independant of the rest of the simulation
1419 initalization. Otherwize a trace option explictly set from gdb
1420 could be overridden by hw_trace.
1422 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1424 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1425 debug.c. It could be much simpler.

1443 string array - use the first entry for the initial file image.
1445 * tree.c (print_string_aray_property): New function - print a

1466 * gen-icache.c (print_icache_extraction): For a cache entry of
1467 the form <name>_is_<const> where it is a boolean field, generate
1468 the result of the expression instead of the expression its self.

1470 then generating corresponding definitions.
1472 * gen-icache.c (print_icache_struct): If there is no cache, do not
1473 output expressions in idecode.h file.
1475 * gen-icache.c (print_icache_body): Output them here.
1477 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1484 * The code that put values in and extracted values from the cache
1485 was too compilicated. The cache table did not allow values to be
1486 computed from cache entries. #defines could only be used when a
1487 cache was present, remove the restriction.
1489 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1490 scratch variable is defined when a cache entry is beinf
1491 filled. Change the definition of a COMPUTE variable to be defined
1492 when the cache entry is being used.
1493 * gen-icache.c: Update.
1495 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1497 * gen-icache.c: Update
1499 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1500 different types of cache code - put into cache, extract from
1501 cache, no cache - an explicit argument to print_icache_body.
1502 * gen-icache.c (print_icache_extraction): Ditto.
1504 * gen-semantics.c (print_c_semantic): Update use.
1505 * gen-idecode.c (print_jump_insn): Update use.
1506 * gen-icache.c (print_icache_function): Update use.
1508 * igen.c (main): Change 'R' option so that it does not force the
1511 * configure.in (enable-sim-icache): Clarify description. Make
1512 #define one of the defaults regardless of the cache. Probably
1513 should revamp and add a separate option.
1515 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1517 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1528 device after it was deleted. Instead add and remove cap's from the
1529 cap db as they are created and deleted. This ensuring that a
1530 capibility is only used during the lifetime of the corresponding
1533 * cap.h, cap.c: Correct cap type - was signed32 should be
1536 * cap.c (cap_add, cap_remove): New methods for cap object that
1537 allow the explicit addition and removal of internal objects that
1538 the cap knows about.
1540 * cap.c (cap_init): Rewrite. Verify that the only objects
1541 remaining in the cap data base are those that were entered first.
1542 Thse objects will be the permenant ones.
1543 * device.c (device_init_address): Remember to initialize the cap
1546 * device.c (device_create_instance_from): Explicitly add device
1547 instances to the cap database. Simplify create code.
