1296 are simply renaming functions, to permit use of XCONCAT2 in both
1297 the macro name and the arguments in a use of such a definition.
1299 2000-11-15 Jim Blandy <jimb@redhat.com>
1301 * sim_calls.c: Doc fix.
1302 (sim_fetch_register, sim_store_register): Call
1303 gdbarch_register_name directly, instead of going through
1304 REGISTER_NAME macro.
1306 2000-10-24 Geoff Keating <geoffk@cygnus.com>
1308 * ppc-instructions (lfsux): Correct XO field of lfsux instruction.

1337 1999-05-08 Felix Lee <flee@cygnus.com>
1339 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
1340 * configure: Regenerated to track ../common/aclocal.m4 changes.
1342 1999-04-02 Keith Seitz <keiths@cygnus.com>
1344 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak

1360 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1362 Make the simulator compatible with the MPC750. It would be nicer
1363 to make this a real multi-sim, but that's more work than we have
1365 * emul_generic.c (emul_add_tree_options): Only require strict
1366 alignment if it was explicitly requested at configuration time.
1367 Don't make it the default for little-endian machines.
1368 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1369 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1370 THRM2, THRM3): Plop in the MPC750 SPR registers.
1371 (DABR): This is weird. This was HID5, but the PPC spec says this
1372 should be DABR; why did some random processor use it for something
1373 else? The HID5 entry dates back to the original checkin of the
1374 simulator code in 1995, so remove it.
1375 * sim_calls.c (register_names): Delete this; since the user can
1376 now change GDB's list of register names dynamically, we can't
1377 pretend there's a static mapping here.
1378 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1379 function to get the register name. That ought to be accurate.
1380 However, we're changing a compile-time dependency (using the
1381 REGISTER_NAMES macro) into a link- and run-time dependency
1382 (calling REGISTER_NAME, which happens to be a function call on the
1385 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1387 * igen.c(gen_semantics_[ch]): setup/use of new option

1396 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

1411 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1412 fractional type, so that quiet NaN's aren't treated like
1415 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1417 * table.c (table_open): For cygwin hosts, we need to use the
1418 return value from the read routine as the number of bytes to
1419 process. This apparently is due to text-mode vs binary-mode. If
1420 the mounts are done text-mode, then the size returnedby fstat()
1421 may be different than the number of bytes "read" in text mode.
1423 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1425 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1441 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
1442 * configure: Regenerate.
1443 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1444 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1446 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1448 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1449 but there was no such target, only plain psim. So I changed the
1450 run target to depend on psim.
1452 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1454 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1455 now defined in ../common/aclocal.m4, and the double definition causes
1456 problems with AC_SUBST of EXEEXT.

1459 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>

1545 mask extracting shift amount. Correctly condition for setting XER
1547 (ldhau): From Johannes Reisinger, update rA after load.
1549 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>

1858 determine the simulation speed by looking at the number of elapsed
1859 ticks recorded by the event queue.
1861 * psim.c (psim_write_register, psim_read_register): Force the cpu
1862 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1863 next cpu would be zero any way.
1865 * mon.c (mon_print_info): If possible, print the system cycle
1866 performance. This is an indication of the number of instructions
1869 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1871 * The code to allow an event queue to be updated during a signal
1872 was missing. For main.c, a cntrl-c simulation termination wasn't
1875 * The simulation would not correctly restart if an event requested
1876 that the simulation be halted.
1878 * psim.c (psim_options): Add hack to -i option to optionally
1879 include a level vis -i2.
1880 (psim_usage): Document.

1928 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1929 to be initialized independant of the rest of the simulation
1930 initalization. Otherwize a trace option explictly set from gdb
1931 could be overridden by hw_trace.
1933 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1935 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1936 debug.c. It could be much simpler.

1978 the form <name>_is_<const> where it is a boolean field, generate
1979 the result of the expression instead of the expression its self.

1981 then generating corresponding definitions.
1983 * gen-icache.c (print_icache_struct): If there is no cache, do not
1984 output expressions in idecode.h file.
1986 * gen-icache.c (print_icache_body): Output them here.

1995 * The code that put values in and extracted values from the cache
1996 was too compilicated. The cache table did not allow values to be
1997 computed from cache entries. #defines could only be used when a
1998 cache was present, remove the restriction.
2000 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
2001 scratch variable is defined when a cache entry is beinf
2002 filled. Change the definition of a COMPUTE variable to be defined
2003 when the cache entry is being used.
2004 * gen-icache.c: Update.
2006 * ld-cache.h, ld-cache.c: Change field names so that their meaning

2015 * gen-semantics.c (print_c_semantic): Update use.
2016 * gen-idecode.c (print_jump_insn): Update use.
2017 * gen-icache.c (print_icache_function): Update use.
2019 * igen.c (main): Change 'R' option so that it does not force the
2022 * configure.in (enable-sim-icache): Clarify description. Make
2023 #define one of the defaults regardless of the cache. Probably
2024 should revamp and add a separate option.

2039 device after it was deleted. Instead add and remove cap's from the
2040 cap db as they are created and deleted. This ensuring that a
2041 capibility is only used during the lifetime of the corresponding
2044 * cap.h, cap.c: Correct cap type - was signed32 should be
2047 * cap.c (cap_add, cap_remove): New methods for cap object that
2048 allow the explicit addition and removal of internal objects that
2049 the cap knows about.

2054 * device.c (device_init_address): Remember to initialize the cap
2057 * device.c (device_create_instance_from): Explicitly add device
2058 instances to the cap database. Simplify create code.
