1313 2000-12-12 Geoffrey Keating <geoffk@redhat.com>

1316 are simply renaming functions, to permit use of XCONCAT2 in both
1317 the macro name and the arguments in a use of such a definition.
1319 2000-11-15 Jim Blandy <jimb@redhat.com>
1321 * sim_calls.c: Doc fix.
1322 (sim_fetch_register, sim_store_register): Call
1323 gdbarch_register_name directly, instead of going through
1324 REGISTER_NAME macro.
1326 2000-10-24 Geoff Keating <geoffk@cygnus.com>
1328 * ppc-instructions (lfsux): Correct XO field of lfsux instruction.

1357 1999-05-08 Felix Lee <flee@cygnus.com>
1359 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
1360 * configure: Regenerated to track ../common/aclocal.m4 changes.
1362 1999-04-02 Keith Seitz <keiths@cygnus.com>
1364 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak

1380 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1382 Make the simulator compatible with the MPC750. It would be nicer
1383 to make this a real multi-sim, but that's more work than we have
1385 * emul_generic.c (emul_add_tree_options): Only require strict
1386 alignment if it was explicitly requested at configuration time.
1387 Don't make it the default for little-endian machines.

1389 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1390 THRM2, THRM3): Plop in the MPC750 SPR registers.
1391 (DABR): This is weird. This was HID5, but the PPC spec says this
1392 should be DABR; why did some random processor use it for something
1393 else? The HID5 entry dates back to the original checkin of the
1394 simulator code in 1995, so remove it.
1395 * sim_calls.c (register_names): Delete this; since the user can
1396 now change GDB's list of register names dynamically, we can't
1397 pretend there's a static mapping here.
1398 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1399 function to get the register name. That ought to be accurate.
1400 However, we're changing a compile-time dependency (using the
1401 REGISTER_NAMES macro) into a link- and run-time dependency
1402 (calling REGISTER_NAME, which happens to be a function call on the
1405 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1407 * igen.c(gen_semantics_[ch]): setup/use of new option

1416 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

1431 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1432 fractional type, so that quiet NaN's aren't treated like
1435 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1437 * table.c (table_open): For cygwin hosts, we need to use the
1438 return value from the read routine as the number of bytes to
1439 process. This apparently is due to text-mode vs binary-mode. If
1440 the mounts are done text-mode, then the size returnedby fstat()
1441 may be different than the number of bytes "read" in text mode.
1443 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1445 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1461 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
1462 * configure: Regenerate.
1463 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1464 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1466 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1468 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1469 but there was no such target, only plain psim. So I changed the
1470 run target to depend on psim.
1472 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1474 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1475 now defined in ../common/aclocal.m4, and the double definition causes
1476 problems with AC_SUBST of EXEEXT.
1477 * configure: Regenerate.
1479 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>

1878 determine the simulation speed by looking at the number of elapsed
1879 ticks recorded by the event queue.
1881 * psim.c (psim_write_register, psim_read_register): Force the cpu
1882 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1883 next cpu would be zero any way.
1885 * mon.c (mon_print_info): If possible, print the system cycle
1886 performance. This is an indication of the number of instructions
1889 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1891 * The code to allow an event queue to be updated during a signal
1892 was missing. For main.c, a cntrl-c simulation termination wasn't
1895 * The simulation would not correctly restart if an event requested
1896 that the simulation be halted.
1898 * psim.c (psim_options): Add hack to -i option to optionally
1899 include a level vis -i2.
1900 (psim_usage): Document.

1919 * gen-idecode.c (print_run_until_stop_body): Call
1920 event_queue_process_events to clear possibly pending events before
1921 starting a simulation run. Re-arange main loop so that simulator
1922 is correctly restarted when an event halts the simulation.

1948 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1949 to be initialized independant of the rest of the simulation
1950 initalization. Otherwize a trace option explictly set from gdb
1951 could be overridden by hw_trace.
1953 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1955 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1956 debug.c. It could be much simpler.

1997 * gen-icache.c (print_icache_extraction): For a cache entry of
1998 the form <name>_is_<const> where it is a boolean field, generate
1999 the result of the expression instead of the expression its self.

2001 then generating corresponding definitions.
2003 * gen-icache.c (print_icache_struct): If there is no cache, do not
2004 output expressions in idecode.h file.
2006 * gen-icache.c (print_icache_body): Output them here.

2015 * The code that put values in and extracted values from the cache
2016 was too compilicated. The cache table did not allow values to be
2017 computed from cache entries. #defines could only be used when a
2018 cache was present, remove the restriction.
2020 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
2021 scratch variable is defined when a cache entry is beinf
2022 filled. Change the definition of a COMPUTE variable to be defined
2023 when the cache entry is being used.
2024 * gen-icache.c: Update.
2026 * ld-cache.h, ld-cache.c: Change field names so that their meaning

2031 different types of cache code - put into cache, extract from
2032 cache, no cache - an explicit argument to print_icache_body.

2035 * gen-semantics.c (print_c_semantic): Update use.
2036 * gen-idecode.c (print_jump_insn): Update use.
2037 * gen-icache.c (print_icache_function): Update use.
2039 * igen.c (main): Change 'R' option so that it does not force the
2042 * configure.in (enable-sim-icache): Clarify description. Make
2043 #define one of the defaults regardless of the cache. Probably
2044 should revamp and add a separate option.
2046 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
2048 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

2059 device after it was deleted. Instead add and remove cap's from the
2060 cap db as they are created and deleted. This ensuring that a
2061 capibility is only used during the lifetime of the corresponding
2064 * cap.h, cap.c: Correct cap type - was signed32 should be

2074 * device.c (device_init_address): Remember to initialize the cap
2077 * device.c (device_create_instance_from): Explicitly add device
2078 instances to the cap database. Simplify create code.
