1278 2000-12-12 Geoffrey Keating <geoffk@redhat.com>

1281 are simply renaming functions, to permit use of XCONCAT2 in both
1282 the macro name and the arguments in a use of such a definition.
1284 2000-11-15 Jim Blandy <jimb@redhat.com>
1286 * sim_calls.c: Doc fix.
1287 (sim_fetch_register, sim_store_register): Call
1288 gdbarch_register_name directly, instead of going through
1289 REGISTER_NAME macro.
1291 2000-10-24 Geoff Keating <geoffk@cygnus.com>
1293 * ppc-instructions (lfsux): Correct XO field of lfsux instruction.

1322 1999-05-08 Felix Lee <flee@cygnus.com>
1324 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
1325 * configure: Regenerated to track ../common/aclocal.m4 changes.
1327 1999-04-02 Keith Seitz <keiths@cygnus.com>
1329 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak

1345 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1347 Make the simulator compatible with the MPC750. It would be nicer
1348 to make this a real multi-sim, but that's more work than we have
1350 * emul_generic.c (emul_add_tree_options): Only require strict
1351 alignment if it was explicitly requested at configuration time.
1352 Don't make it the default for little-endian machines.

1354 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1355 THRM2, THRM3): Plop in the MPC750 SPR registers.
1356 (DABR): This is weird. This was HID5, but the PPC spec says this
1357 should be DABR; why did some random processor use it for something
1358 else? The HID5 entry dates back to the original checkin of the
1359 simulator code in 1995, so remove it.
1360 * sim_calls.c (register_names): Delete this; since the user can
1361 now change GDB's list of register names dynamically, we can't
1362 pretend there's a static mapping here.
1363 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1364 function to get the register name. That ought to be accurate.
1365 However, we're changing a compile-time dependency (using the
1366 REGISTER_NAMES macro) into a link- and run-time dependency
1367 (calling REGISTER_NAME, which happens to be a function call on the
1370 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1372 * igen.c(gen_semantics_[ch]): setup/use of new option
1374 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.

1377 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
1379 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
1381 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

1396 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1397 fractional type, so that quiet NaN's aren't treated like
1400 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1402 * table.c (table_open): For cygwin hosts, we need to use the
1403 return value from the read routine as the number of bytes to
1404 process. This apparently is due to text-mode vs binary-mode. If
1405 the mounts are done text-mode, then the size returnedby fstat()
1406 may be different than the number of bytes "read" in text mode.
1408 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1410 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1426 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
1427 * configure: Regenerate.
1428 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1429 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1431 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1433 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1434 but there was no such target, only plain psim. So I changed the
1435 run target to depend on psim.
1437 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1439 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1440 now defined in ../common/aclocal.m4, and the double definition causes
1441 problems with AC_SUBST of EXEEXT.

1444 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>

1530 mask extracting shift amount. Correctly condition for setting XER
1532 (ldhau): From Johannes Reisinger, update rA after load.
1534 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
1536 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,

1843 determine the simulation speed by looking at the number of elapsed
1844 ticks recorded by the event queue.
1846 * psim.c (psim_write_register, psim_read_register): Force the cpu
1847 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1848 next cpu would be zero any way.
1850 * mon.c (mon_print_info): If possible, print the system cycle
1851 performance. This is an indication of the number of instructions
1854 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1856 * The code to allow an event queue to be updated during a signal
1857 was missing. For main.c, a cntrl-c simulation termination wasn't
1860 * The simulation would not correctly restart if an event requested
1861 that the simulation be halted.
1863 * psim.c (psim_options): Add hack to -i option to optionally
1864 include a level vis -i2.
1865 (psim_usage): Document.

1884 * gen-idecode.c (print_run_until_stop_body): Call
1885 event_queue_process_events to clear possibly pending events before
1886 starting a simulation run. Re-arange main loop so that simulator
1887 is correctly restarted when an event halts the simulation.

1913 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1914 to be initialized independant of the rest of the simulation
1915 initalization. Otherwize a trace option explictly set from gdb
1916 could be overridden by hw_trace.
1918 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1920 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1921 debug.c. It could be much simpler.

1939 string array - use the first entry for the initial file image.
1941 * tree.c (print_string_aray_property): New function - print a

1963 the form <name>_is_<const> where it is a boolean field, generate
1964 the result of the expression instead of the expression its self.

1966 then generating corresponding definitions.
1968 * gen-icache.c (print_icache_struct): If there is no cache, do not
1969 output expressions in idecode.h file.
1971 * gen-icache.c (print_icache_body): Output them here.
1973 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1980 * The code that put values in and extracted values from the cache
1981 was too compilicated. The cache table did not allow values to be
1982 computed from cache entries. #defines could only be used when a
1983 cache was present, remove the restriction.
1985 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1986 scratch variable is defined when a cache entry is beinf
1987 filled. Change the definition of a COMPUTE variable to be defined
1988 when the cache entry is being used.
1989 * gen-icache.c: Update.
1991 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1993 * gen-icache.c: Update
1995 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1996 different types of cache code - put into cache, extract from
1997 cache, no cache - an explicit argument to print_icache_body.
1998 * gen-icache.c (print_icache_extraction): Ditto.
2000 * gen-semantics.c (print_c_semantic): Update use.
2001 * gen-idecode.c (print_jump_insn): Update use.
2002 * gen-icache.c (print_icache_function): Update use.
2004 * igen.c (main): Change 'R' option so that it does not force the
2007 * configure.in (enable-sim-icache): Clarify description. Make
2008 #define one of the defaults regardless of the cache. Probably
2009 should revamp and add a separate option.
2011 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
2013 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

2024 device after it was deleted. Instead add and remove cap's from the
2025 cap db as they are created and deleted. This ensuring that a
2026 capibility is only used during the lifetime of the corresponding
2029 * cap.h, cap.c: Correct cap type - was signed32 should be
2032 * cap.c (cap_add, cap_remove): New methods for cap object that
2033 allow the explicit addition and removal of internal objects that
2034 the cap knows about.

2039 * device.c (device_init_address): Remember to initialize the cap
2042 * device.c (device_create_instance_from): Explicitly add device
2043 instances to the cap database. Simplify create code.
