811 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
813 * sim-endian.h: Don't have parameters on macro definitions which
814 are simply renaming functions, to permit use of XCONCAT2 in both
815 the macro name and the arguments in a use of such a definition.
817 2000-11-15 Jim Blandy <jimb@redhat.com>
819 * sim_calls.c: Doc fix.
820 (sim_fetch_register, sim_store_register): Call

855 1999-05-08 Felix Lee <flee@cygnus.com>
857 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
858 * configure: Regenerated to track ../common/aclocal.m4 changes.
860 1999-04-02 Keith Seitz <keiths@cygnus.com>

866 after the specified POLL_QUIT_INTERVAL.
868 1999-02-22 Jim Lemke <jlemke@cygnus.com>
870 * dc-complex: Force expansion on all bits of field BO.

878 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
880 Make the simulator compatible with the MPC750. It would be nicer
881 to make this a real multi-sim, but that's more work than we have
883 * emul_generic.c (emul_add_tree_options): Only require strict
884 alignment if it was explicitly requested at configuration time.
885 Don't make it the default for little-endian machines.
886 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
887 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
888 THRM2, THRM3): Plop in the MPC750 SPR registers.
889 (DABR): This is weird. This was HID5, but the PPC spec says this
890 should be DABR; why did some random processor use it for something
891 else? The HID5 entry dates back to the original checkin of the
892 simulator code in 1995, so remove it.
893 * sim_calls.c (register_names): Delete this; since the user can
894 now change GDB's list of register names dynamically, we can't
895 pretend there's a static mapping here.
896 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
897 function to get the register name. That ought to be accurate.
898 However, we're changing a compile-time dependency (using the
899 REGISTER_NAMES macro) into a link- and run-time dependency
900 (calling REGISTER_NAME, which happens to be a function call on the
903 1999-01-22 Jim Lemke <jlemke@cygnus.com>
905 * igen.c(gen_semantics_[ch]): setup/use of new option

909 psim.c(is_num - added, psim_options): Parse and init new option.
910 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
912 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
914 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

929 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
930 fractional type, so that quiet NaN's aren't treated like
933 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
935 * table.c (table_open): For cygwin hosts, we need to use the
936 return value from the read routine as the number of bytes to
937 process. This apparently is due to text-mode vs binary-mode. If
938 the mounts are done text-mode, then the size returnedby fstat()
939 may be different than the number of bytes "read" in text mode.
941 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
943 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

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

977 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>

1376 determine the simulation speed by looking at the number of elapsed
1377 ticks recorded by the event queue.
1379 * psim.c (psim_write_register, psim_read_register): Force the cpu
1380 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1381 next cpu would be zero any way.
1383 * mon.c (mon_print_info): If possible, print the system cycle
1384 performance. This is an indication of the number of instructions
1387 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1389 * The code to allow an event queue to be updated during a signal
1390 was missing. For main.c, a cntrl-c simulation termination wasn't
1393 * The simulation would not correctly restart if an event requested
1394 that the simulation be halted.
1396 * psim.c (psim_options): Add hack to -i option to optionally
1397 include a level vis -i2.
1398 (psim_usage): Document.

1414 (event_queue_tick): Check that processing isn't still being
1417 * gen-idecode.c (print_run_until_stop_body): Call
1418 event_queue_process_events to clear possibly pending events before
1419 starting a simulation run. Re-arange main loop so that simulator
1420 is correctly restarted when an event halts the simulation.

1446 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1447 to be initialized independant of the rest of the simulation
1448 initalization. Otherwize a trace option explictly set from gdb
1449 could be overridden by hw_trace.
1451 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1453 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1454 debug.c. It could be much simpler.
1456 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1472 string array - use the first entry for the initial file image.
1474 * tree.c (print_string_aray_property): New function - print a

1495 * gen-icache.c (print_icache_extraction): For a cache entry of
1496 the form <name>_is_<const> where it is a boolean field, generate
1497 the result of the expression instead of the expression its self.

1499 then generating corresponding definitions.
1501 * gen-icache.c (print_icache_struct): If there is no cache, do not
1502 output expressions in idecode.h file.
1504 * gen-icache.c (print_icache_body): Output them here.
1506 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1511 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1513 * The code that put values in and extracted values from the cache
1514 was too compilicated. The cache table did not allow values to be
1515 computed from cache entries. #defines could only be used when a
1516 cache was present, remove the restriction.
1518 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1519 scratch variable is defined when a cache entry is beinf
1520 filled. Change the definition of a COMPUTE variable to be defined
1521 when the cache entry is being used.
1522 * gen-icache.c: Update.
1524 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1525 is more obvious. old_name->field_name, new_name->derived_name.
1526 * gen-icache.c: Update
1528 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1529 different types of cache code - put into cache, extract from
1530 cache, no cache - an explicit argument to print_icache_body.
1531 * gen-icache.c (print_icache_extraction): Ditto.
1533 * gen-semantics.c (print_c_semantic): Update use.
1534 * gen-idecode.c (print_jump_insn): Update use.
1535 * gen-icache.c (print_icache_function): Update use.
1537 * igen.c (main): Change 'R' option so that it does not force the
1540 * configure.in (enable-sim-icache): Clarify description. Make
1541 #define one of the defaults regardless of the cache. Probably
1542 should revamp and add a separate option.
1544 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1546 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1557 device after it was deleted. Instead add and remove cap's from the
1558 cap db as they are created and deleted. This ensuring that a
1559 capibility is only used during the lifetime of the corresponding
1562 * cap.h, cap.c: Correct cap type - was signed32 should be
1565 * cap.c (cap_add, cap_remove): New methods for cap object that
1566 allow the explicit addition and removal of internal objects that
1567 the cap knows about.
1569 * cap.c (cap_init): Rewrite. Verify that the only objects
1570 remaining in the cap data base are those that were entered first.
1571 Thse objects will be the permenant ones.
1572 * device.c (device_init_address): Remember to initialize the cap
1575 * device.c (device_create_instance_from): Explicitly add device
1576 instances to the cap database. Simplify create code.
