1249 are simply renaming functions, to permit use of XCONCAT2 in both
1250 the macro name and the arguments in a use of such a definition.
1252 2000-11-15 Jim Blandy <jimb@redhat.com>
1254 * sim_calls.c: Doc fix.
1255 (sim_fetch_register, sim_store_register): Call
1256 gdbarch_register_name directly, instead of going through
1257 REGISTER_NAME macro.
1259 2000-10-24 Geoff Keating <geoffk@cygnus.com>
1261 * ppc-instructions (lfsux): Correct XO field of lfsux instruction.

1290 1999-05-08 Felix Lee <flee@cygnus.com>
1292 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
1293 * configure: Regenerated to track ../common/aclocal.m4 changes.
1295 1999-04-02 Keith Seitz <keiths@cygnus.com>
1297 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak

1313 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1315 Make the simulator compatible with the MPC750. It would be nicer
1316 to make this a real multi-sim, but that's more work than we have
1318 * emul_generic.c (emul_add_tree_options): Only require strict
1319 alignment if it was explicitly requested at configuration time.
1320 Don't make it the default for little-endian machines.

1322 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1323 THRM2, THRM3): Plop in the MPC750 SPR registers.
1324 (DABR): This is weird. This was HID5, but the PPC spec says this
1325 should be DABR; why did some random processor use it for something
1326 else? The HID5 entry dates back to the original checkin of the
1327 simulator code in 1995, so remove it.
1328 * sim_calls.c (register_names): Delete this; since the user can
1329 now change GDB's list of register names dynamically, we can't
1330 pretend there's a static mapping here.
1331 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1332 function to get the register name. That ought to be accurate.
1333 However, we're changing a compile-time dependency (using the
1334 REGISTER_NAMES macro) into a link- and run-time dependency
1335 (calling REGISTER_NAME, which happens to be a function call on the
1338 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1340 * igen.c(gen_semantics_[ch]): setup/use of new option

1364 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1365 fractional type, so that quiet NaN's aren't treated like
1368 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1370 * table.c (table_open): For cygwin hosts, we need to use the
1371 return value from the read routine as the number of bytes to
1372 process. This apparently is due to text-mode vs binary-mode. If
1373 the mounts are done text-mode, then the size returnedby fstat()
1374 may be different than the number of bytes "read" in text mode.
1376 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1378 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1390 return zero when nothing to do.
1392 1998-06-26 Michael Meissner <meissner@cygnus.com>
1394 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
1395 * configure: Regenerate.
1396 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1397 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1399 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1401 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1402 but there was no such target, only plain psim. So I changed the
1403 run target to depend on psim.
1405 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1407 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1408 now defined in ../common/aclocal.m4, and the double definition causes
1409 problems with AC_SUBST of EXEEXT.

1412 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>

1497 * ppc-instructions (sraw, slw, srw): From Charles Lefurgy, Fix
1498 mask extracting shift amount. Correctly condition for setting XER
1500 (ldhau): From Johannes Reisinger, update rA after load.
1502 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
1504 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,

1811 determine the simulation speed by looking at the number of elapsed
1812 ticks recorded by the event queue.
1814 * psim.c (psim_write_register, psim_read_register): Force the cpu
1815 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1816 next cpu would be zero any way.
1818 * mon.c (mon_print_info): If possible, print the system cycle
1819 performance. This is an indication of the number of instructions
1822 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1824 * The code to allow an event queue to be updated during a signal
1825 was missing. For main.c, a cntrl-c simulation termination wasn't
1828 * The simulation would not correctly restart if an event requested
1829 that the simulation be halted.
1831 * psim.c (psim_options): Add hack to -i option to optionally
1832 include a level vis -i2.
1833 (psim_usage): Document.

1852 * gen-idecode.c (print_run_until_stop_body): Call
1853 event_queue_process_events to clear possibly pending events before
1854 starting a simulation run. Re-arange main loop so that simulator
1855 is correctly restarted when an event halts the simulation.

1881 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1882 to be initialized independant of the rest of the simulation
1883 initalization. Otherwize a trace option explictly set from gdb
1884 could be overridden by hw_trace.
1886 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1888 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1889 debug.c. It could be much simpler.
1891 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1907 string array - use the first entry for the initial file image.
1909 * tree.c (print_string_aray_property): New function - print a

1931 the form <name>_is_<const> where it is a boolean field, generate
1932 the result of the expression instead of the expression its self.

1937 output expressions in idecode.h file.
1939 * gen-icache.c (print_icache_body): Output them here.

1948 * The code that put values in and extracted values from the cache
1949 was too compilicated. The cache table did not allow values to be
1950 computed from cache entries. #defines could only be used when a
1951 cache was present, remove the restriction.
1953 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1954 scratch variable is defined when a cache entry is beinf
1955 filled. Change the definition of a COMPUTE variable to be defined
1956 when the cache entry is being used.
1957 * gen-icache.c: Update.
1959 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1968 * gen-semantics.c (print_c_semantic): Update use.
1969 * gen-idecode.c (print_jump_insn): Update use.
1970 * gen-icache.c (print_icache_function): Update use.
1972 * igen.c (main): Change 'R' option so that it does not force the
1975 * configure.in (enable-sim-icache): Clarify description. Make
1976 #define one of the defaults regardless of the cache. Probably
1977 should revamp and add a separate option.
1979 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1981 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
