1289 are simply renaming functions, to permit use of XCONCAT2 in both
1290 the macro name and the arguments in a use of such a definition.
1292 2000-11-15 Jim Blandy <jimb@redhat.com>
1294 * sim_calls.c: Doc fix.
1295 (sim_fetch_register, sim_store_register): Call
1296 gdbarch_register_name directly, instead of going through
1297 REGISTER_NAME macro.
1299 2000-10-24 Geoff Keating <geoffk@cygnus.com>
1301 * ppc-instructions (lfsux): Correct XO field of lfsux instruction.

1330 1999-05-08 Felix Lee <flee@cygnus.com>
1332 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
1333 * configure: Regenerated to track ../common/aclocal.m4 changes.
1335 1999-04-02 Keith Seitz <keiths@cygnus.com>
1337 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak

1353 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1355 Make the simulator compatible with the MPC750. It would be nicer
1356 to make this a real multi-sim, but that's more work than we have
1358 * emul_generic.c (emul_add_tree_options): Only require strict
1359 alignment if it was explicitly requested at configuration time.
1360 Don't make it the default for little-endian machines.

1362 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1363 THRM2, THRM3): Plop in the MPC750 SPR registers.
1364 (DABR): This is weird. This was HID5, but the PPC spec says this
1365 should be DABR; why did some random processor use it for something
1366 else? The HID5 entry dates back to the original checkin of the
1367 simulator code in 1995, so remove it.
1368 * sim_calls.c (register_names): Delete this; since the user can
1369 now change GDB's list of register names dynamically, we can't
1370 pretend there's a static mapping here.
1371 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1372 function to get the register name. That ought to be accurate.
1373 However, we're changing a compile-time dependency (using the
1374 REGISTER_NAMES macro) into a link- and run-time dependency
1375 (calling REGISTER_NAME, which happens to be a function call on the
1378 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1380 * igen.c(gen_semantics_[ch]): setup/use of new option
1382 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.

1384 psim.c(is_num - added, psim_options): Parse and init new option.
1385 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
1387 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
1389 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

1404 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1405 fractional type, so that quiet NaN's aren't treated like
1408 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1410 * table.c (table_open): For cygwin hosts, we need to use the
1411 return value from the read routine as the number of bytes to
1412 process. This apparently is due to text-mode vs binary-mode. If
1413 the mounts are done text-mode, then the size returnedby fstat()
1414 may be different than the number of bytes "read" in text mode.
1416 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1418 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1434 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
1435 * configure: Regenerate.
1436 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1437 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1439 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1441 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1442 but there was no such target, only plain psim. So I changed the
1443 run target to depend on psim.
1445 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1447 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1448 now defined in ../common/aclocal.m4, and the double definition causes
1449 problems with AC_SUBST of EXEEXT.

1452 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>

1538 mask extracting shift amount. Correctly condition for setting XER
1540 (ldhau): From Johannes Reisinger, update rA after load.
1542 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
1544 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,

1851 determine the simulation speed by looking at the number of elapsed
1852 ticks recorded by the event queue.
1854 * psim.c (psim_write_register, psim_read_register): Force the cpu
1855 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1856 next cpu would be zero any way.
1858 * mon.c (mon_print_info): If possible, print the system cycle
1859 performance. This is an indication of the number of instructions
1862 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1864 * The code to allow an event queue to be updated during a signal
1865 was missing. For main.c, a cntrl-c simulation termination wasn't
1868 * The simulation would not correctly restart if an event requested
1869 that the simulation be halted.
1871 * psim.c (psim_options): Add hack to -i option to optionally
1872 include a level vis -i2.
1873 (psim_usage): Document.

1921 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1922 to be initialized independant of the rest of the simulation
1923 initalization. Otherwize a trace option explictly set from gdb
1924 could be overridden by hw_trace.
1926 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1928 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1929 debug.c. It could be much simpler.

1971 the form <name>_is_<const> where it is a boolean field, generate
1972 the result of the expression instead of the expression its self.

1977 output expressions in idecode.h file.
1979 * gen-icache.c (print_icache_body): Output them here.

1988 * The code that put values in and extracted values from the cache
1989 was too compilicated. The cache table did not allow values to be
1990 computed from cache entries. #defines could only be used when a
1991 cache was present, remove the restriction.
1993 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1994 scratch variable is defined when a cache entry is beinf
1995 filled. Change the definition of a COMPUTE variable to be defined
1996 when the cache entry is being used.
1997 * gen-icache.c: Update.
1999 * ld-cache.h, ld-cache.c: Change field names so that their meaning

2008 * gen-semantics.c (print_c_semantic): Update use.
2009 * gen-idecode.c (print_jump_insn): Update use.
2010 * gen-icache.c (print_icache_function): Update use.
2012 * igen.c (main): Change 'R' option so that it does not force the
2015 * configure.in (enable-sim-icache): Clarify description. Make
2016 #define one of the defaults regardless of the cache. Probably
2017 should revamp and add a separate option.
2019 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
2021 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
