851 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
853 * sim-endian.h: Don't have parameters on macro definitions which
854 are simply renaming functions, to permit use of XCONCAT2 in both
855 the macro name and the arguments in a use of such a definition.
857 2000-11-15 Jim Blandy <jimb@redhat.com>
859 * sim_calls.c: Doc fix.
860 (sim_fetch_register, sim_store_register): Call

895 1999-05-08 Felix Lee <flee@cygnus.com>
897 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
898 * configure: Regenerated to track ../common/aclocal.m4 changes.
900 1999-04-02 Keith Seitz <keiths@cygnus.com>

906 after the specified POLL_QUIT_INTERVAL.
908 1999-02-22 Jim Lemke <jlemke@cygnus.com>
910 * dc-complex: Force expansion on all bits of field BO.

918 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
920 Make the simulator compatible with the MPC750. It would be nicer
921 to make this a real multi-sim, but that's more work than we have
923 * emul_generic.c (emul_add_tree_options): Only require strict
924 alignment if it was explicitly requested at configuration time.
925 Don't make it the default for little-endian machines.
926 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
927 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
928 THRM2, THRM3): Plop in the MPC750 SPR registers.
929 (DABR): This is weird. This was HID5, but the PPC spec says this
930 should be DABR; why did some random processor use it for something
931 else? The HID5 entry dates back to the original checkin of the
932 simulator code in 1995, so remove it.
933 * sim_calls.c (register_names): Delete this; since the user can
934 now change GDB's list of register names dynamically, we can't
935 pretend there's a static mapping here.
936 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
937 function to get the register name. That ought to be accurate.
938 However, we're changing a compile-time dependency (using the
939 REGISTER_NAMES macro) into a link- and run-time dependency
940 (calling REGISTER_NAME, which happens to be a function call on the
943 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

1000 * configure: Regenerate.
1001 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1002 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1004 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1006 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1007 but there was no such target, only plain psim. So I changed the
1008 run target to depend on psim.
1010 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1012 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1013 now defined in ../common/aclocal.m4, and the double definition causes
1014 problems with AC_SUBST of EXEEXT.
1015 * configure: Regenerate.
1017 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>

1416 determine the simulation speed by looking at the number of elapsed
1417 ticks recorded by the event queue.
1419 * psim.c (psim_write_register, psim_read_register): Force the cpu
1420 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1421 next cpu would be zero any way.
1423 * mon.c (mon_print_info): If possible, print the system cycle
1424 performance. This is an indication of the number of instructions
1427 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1429 * The code to allow an event queue to be updated during a signal
1430 was missing. For main.c, a cntrl-c simulation termination wasn't
1433 * The simulation would not correctly restart if an event requested
1434 that the simulation be halted.
1436 * psim.c (psim_options): Add hack to -i option to optionally
1437 include a level vis -i2.
1438 (psim_usage): Document.

1454 (event_queue_tick): Check that processing isn't still being
1457 * gen-idecode.c (print_run_until_stop_body): Call
1458 event_queue_process_events to clear possibly pending events before
1459 starting a simulation run. Re-arange main loop so that simulator
1460 is correctly restarted when an event halts the simulation.
1462 * psim.c (psim_halt): Handle an event halting the simulation.
1463 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1466 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1484 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1486 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1487 to be initialized independant of the rest of the simulation
1488 initalization. Otherwize a trace option explictly set from gdb
1489 could be overridden by hw_trace.
1491 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1493 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1494 debug.c. It could be much simpler.
1496 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1509 media. If no file image is specified, use the next one in the
1510 image property list.
1511 (hw_disk_init_address): Change the file property so that it is a
1512 string array - use the first entry for the initial file image.
1514 * tree.c (print_string_aray_property): New function - print a
1516 (print_properties): Adjust.

1531 as RA_is_0. If possible generate the result of the expression so
1532 that the compiler gets a better chance of eliminating dead
1535 * gen-icache.c (print_icache_extraction): For a cache entry of
1536 the form <name>_is_<const> where it is a boolean field, generate
1537 the result of the expression instead of the expression its self.
1538 (print_icache_body): Remove code that was looking for *_is_0 and
1539 then generating corresponding definitions.
1541 * gen-icache.c (print_icache_struct): If there is no cache, do not
1542 output expressions in idecode.h file.
1544 * gen-icache.c (print_icache_body): Output them here.
1546 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1551 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1553 * The code that put values in and extracted values from the cache
1554 was too compilicated. The cache table did not allow values to be
1555 computed from cache entries. #defines could only be used when a
1556 cache was present, remove the restriction.
1558 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1559 scratch variable is defined when a cache entry is beinf
1560 filled. Change the definition of a COMPUTE variable to be defined
1561 when the cache entry is being used.
1562 * gen-icache.c: Update.
1564 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1565 is more obvious. old_name->field_name, new_name->derived_name.
1566 * gen-icache.c: Update
1568 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1569 different types of cache code - put into cache, extract from
1570 cache, no cache - an explicit argument to print_icache_body.
1571 * gen-icache.c (print_icache_extraction): Ditto.
1573 * gen-semantics.c (print_c_semantic): Update use.
1574 * gen-idecode.c (print_jump_insn): Update use.
1575 * gen-icache.c (print_icache_function): Update use.
1577 * igen.c (main): Change 'R' option so that it does not force the
1580 * configure.in (enable-sim-icache): Clarify description. Make
