1236 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
1238 * sim-endian.h: Don't have parameters on macro definitions which
1239 are simply renaming functions, to permit use of XCONCAT2 in both
1240 the macro name and the arguments in a use of such a definition.
1242 2000-11-15 Jim Blandy <jimb@redhat.com>
1244 * sim_calls.c: Doc fix.
1245 (sim_fetch_register, sim_store_register): Call
1246 gdbarch_register_name directly, instead of going through
1247 REGISTER_NAME macro.
1249 2000-10-24 Geoff Keating <geoffk@cygnus.com>
1251 * ppc-instructions (lfsux): Correct XO field of lfsux instruction.

1280 1999-05-08 Felix Lee <flee@cygnus.com>
1282 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
1283 * configure: Regenerated to track ../common/aclocal.m4 changes.
1285 1999-04-02 Keith Seitz <keiths@cygnus.com>
1287 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak

1303 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1305 Make the simulator compatible with the MPC750. It would be nicer
1306 to make this a real multi-sim, but that's more work than we have
1308 * emul_generic.c (emul_add_tree_options): Only require strict
1309 alignment if it was explicitly requested at configuration time.
1310 Don't make it the default for little-endian machines.

1312 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1313 THRM2, THRM3): Plop in the MPC750 SPR registers.
1314 (DABR): This is weird. This was HID5, but the PPC spec says this
1315 should be DABR; why did some random processor use it for something
1316 else? The HID5 entry dates back to the original checkin of the
1317 simulator code in 1995, so remove it.
1318 * sim_calls.c (register_names): Delete this; since the user can
1319 now change GDB's list of register names dynamically, we can't
1320 pretend there's a static mapping here.
1321 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1322 function to get the register name. That ought to be accurate.
1323 However, we're changing a compile-time dependency (using the
1324 REGISTER_NAMES macro) into a link- and run-time dependency
1325 (calling REGISTER_NAME, which happens to be a function call on the
1328 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1330 * igen.c(gen_semantics_[ch]): setup/use of new option

1354 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1355 fractional type, so that quiet NaN's aren't treated like
1358 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1360 * table.c (table_open): For cygwin hosts, we need to use the
1361 return value from the read routine as the number of bytes to
1362 process. This apparently is due to text-mode vs binary-mode. If
1363 the mounts are done text-mode, then the size returnedby fstat()
1364 may be different than the number of bytes "read" in text mode.
1366 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1368 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1380 return zero when nothing to do.
1382 1998-06-26 Michael Meissner <meissner@cygnus.com>
1384 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
1385 * configure: Regenerate.
1386 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1387 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1389 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1391 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1392 but there was no such target, only plain psim. So I changed the
1393 run target to depend on psim.
1395 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1397 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1398 now defined in ../common/aclocal.m4, and the double definition causes
1399 problems with AC_SUBST of EXEEXT.

1402 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>

1488 mask extracting shift amount. Correctly condition for setting XER
1490 (ldhau): From Johannes Reisinger, update rA after load.
1492 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>

1801 determine the simulation speed by looking at the number of elapsed
1802 ticks recorded by the event queue.
1804 * psim.c (psim_write_register, psim_read_register): Force the cpu
1805 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1806 next cpu would be zero any way.
1808 * mon.c (mon_print_info): If possible, print the system cycle
1809 performance. This is an indication of the number of instructions
1812 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1814 * The code to allow an event queue to be updated during a signal
1815 was missing. For main.c, a cntrl-c simulation termination wasn't
1818 * The simulation would not correctly restart if an event requested
1819 that the simulation be halted.
1821 * psim.c (psim_options): Add hack to -i option to optionally
1822 include a level vis -i2.
1823 (psim_usage): Document.

1842 * gen-idecode.c (print_run_until_stop_body): Call
1843 event_queue_process_events to clear possibly pending events before
1844 starting a simulation run. Re-arange main loop so that simulator
1845 is correctly restarted when an event halts the simulation.

1871 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1872 to be initialized independant of the rest of the simulation
1873 initalization. Otherwize a trace option explictly set from gdb
1874 could be overridden by hw_trace.
1876 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1878 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1879 debug.c. It could be much simpler.

1897 string array - use the first entry for the initial file image.
1899 * tree.c (print_string_aray_property): New function - print a

1921 the form <name>_is_<const> where it is a boolean field, generate
1922 the result of the expression instead of the expression its self.

1927 output expressions in idecode.h file.
1929 * gen-icache.c (print_icache_body): Output them here.

1938 * The code that put values in and extracted values from the cache
1939 was too compilicated. The cache table did not allow values to be
1940 computed from cache entries. #defines could only be used when a
1941 cache was present, remove the restriction.
1943 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1944 scratch variable is defined when a cache entry is beinf
1945 filled. Change the definition of a COMPUTE variable to be defined
1946 when the cache entry is being used.
1947 * gen-icache.c: Update.
1949 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1958 * gen-semantics.c (print_c_semantic): Update use.
1959 * gen-idecode.c (print_jump_insn): Update use.
1960 * gen-icache.c (print_icache_function): Update use.
1962 * igen.c (main): Change 'R' option so that it does not force the
1965 * configure.in (enable-sim-icache): Clarify description. Make
1966 #define one of the defaults regardless of the cache. Probably
1967 should revamp and add a separate option.
1969 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1971 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
