834 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
836 * sim-endian.h: Don't have parameters on macro definitions which
837 are simply renaming functions, to permit use of XCONCAT2 in both
838 the macro name and the arguments in a use of such a definition.
840 2000-11-15 Jim Blandy <jimb@redhat.com>
842 * sim_calls.c: Doc fix.
843 (sim_fetch_register, sim_store_register): Call

878 1999-05-08 Felix Lee <flee@cygnus.com>
880 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
881 * configure: Regenerated to track ../common/aclocal.m4 changes.
883 1999-04-02 Keith Seitz <keiths@cygnus.com>

901 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
903 Make the simulator compatible with the MPC750. It would be nicer
904 to make this a real multi-sim, but that's more work than we have
906 * emul_generic.c (emul_add_tree_options): Only require strict
907 alignment if it was explicitly requested at configuration time.
908 Don't make it the default for little-endian machines.
909 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
910 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
911 THRM2, THRM3): Plop in the MPC750 SPR registers.
912 (DABR): This is weird. This was HID5, but the PPC spec says this
913 should be DABR; why did some random processor use it for something
914 else? The HID5 entry dates back to the original checkin of the
915 simulator code in 1995, so remove it.
916 * sim_calls.c (register_names): Delete this; since the user can
917 now change GDB's list of register names dynamically, we can't
918 pretend there's a static mapping here.
919 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
920 function to get the register name. That ought to be accurate.
921 However, we're changing a compile-time dependency (using the
922 REGISTER_NAMES macro) into a link- and run-time dependency
923 (calling REGISTER_NAME, which happens to be a function call on the
926 1999-01-22 Jim Lemke <jlemke@cygnus.com>
928 * igen.c(gen_semantics_[ch]): setup/use of new option

932 psim.c(is_num - added, psim_options): Parse and init new option.
933 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

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

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

1000 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>

1399 determine the simulation speed by looking at the number of elapsed
1400 ticks recorded by the event queue.
1402 * psim.c (psim_write_register, psim_read_register): Force the cpu
1403 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1404 next cpu would be zero any way.
1406 * mon.c (mon_print_info): If possible, print the system cycle
1407 performance. This is an indication of the number of instructions
1410 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1412 * The code to allow an event queue to be updated during a signal
1413 was missing. For main.c, a cntrl-c simulation termination wasn't
1416 * The simulation would not correctly restart if an event requested
1417 that the simulation be halted.
1419 * psim.c (psim_options): Add hack to -i option to optionally
1420 include a level vis -i2.
1421 (psim_usage): Document.

1437 (event_queue_tick): Check that processing isn't still being
1440 * gen-idecode.c (print_run_until_stop_body): Call
1441 event_queue_process_events to clear possibly pending events before
1442 starting a simulation run. Re-arange main loop so that simulator
1443 is correctly restarted when an event halts the simulation.
1445 * psim.c (psim_halt): Handle an event halting the simulation.
1446 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1449 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1467 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1469 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1470 to be initialized independant of the rest of the simulation
1471 initalization. Otherwize a trace option explictly set from gdb
1472 could be overridden by hw_trace.
1474 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1476 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1477 debug.c. It could be much simpler.
1479 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1495 string array - use the first entry for the initial file image.
1497 * tree.c (print_string_aray_property): New function - print a
1499 (print_properties): Adjust.

1514 as RA_is_0. If possible generate the result of the expression so
1515 that the compiler gets a better chance of eliminating dead
1518 * gen-icache.c (print_icache_extraction): For a cache entry of
1519 the form <name>_is_<const> where it is a boolean field, generate
1520 the result of the expression instead of the expression its self.
1521 (print_icache_body): Remove code that was looking for *_is_0 and
1522 then generating corresponding definitions.
1524 * gen-icache.c (print_icache_struct): If there is no cache, do not
1525 output expressions in idecode.h file.
1527 * gen-icache.c (print_icache_body): Output them here.
1529 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1532 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
1534 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1536 * The code that put values in and extracted values from the cache
1537 was too compilicated. The cache table did not allow values to be
1538 computed from cache entries. #defines could only be used when a
1539 cache was present, remove the restriction.
1541 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1542 scratch variable is defined when a cache entry is beinf
1543 filled. Change the definition of a COMPUTE variable to be defined
1544 when the cache entry is being used.
1545 * gen-icache.c: Update.
1547 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1548 is more obvious. old_name->field_name, new_name->derived_name.
1549 * gen-icache.c: Update
1551 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1552 different types of cache code - put into cache, extract from
1553 cache, no cache - an explicit argument to print_icache_body.
1554 * gen-icache.c (print_icache_extraction): Ditto.
1556 * gen-semantics.c (print_c_semantic): Update use.
1557 * gen-idecode.c (print_jump_insn): Update use.
1558 * gen-icache.c (print_icache_function): Update use.
1560 * igen.c (main): Change 'R' option so that it does not force the
1563 * configure.in (enable-sim-icache): Clarify description. Make
1564 #define one of the defaults regardless of the cache. Probably
1565 should revamp and add a separate option.
1567 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1569 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
