685 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
687 * sim-endian.h: Don't have parameters on macro definitions which
688 are simply renaming functions, to permit use of XCONCAT2 in both
689 the macro name and the arguments in a use of such a definition.
691 2000-11-15 Jim Blandy <jimb@redhat.com>
693 * sim_calls.c: Doc fix.
694 (sim_fetch_register, sim_store_register): Call

729 1999-05-08 Felix Lee <flee@cygnus.com>
731 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
732 * configure: Regenerated to track ../common/aclocal.m4 changes.
734 1999-04-02 Keith Seitz <keiths@cygnus.com>

752 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
754 Make the simulator compatible with the MPC750. It would be nicer
755 to make this a real multi-sim, but that's more work than we have
757 * emul_generic.c (emul_add_tree_options): Only require strict
758 alignment if it was explicitly requested at configuration time.
759 Don't make it the default for little-endian machines.
760 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
761 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
762 THRM2, THRM3): Plop in the MPC750 SPR registers.
763 (DABR): This is weird. This was HID5, but the PPC spec says this
764 should be DABR; why did some random processor use it for something
765 else? The HID5 entry dates back to the original checkin of the
766 simulator code in 1995, so remove it.
767 * sim_calls.c (register_names): Delete this; since the user can
768 now change GDB's list of register names dynamically, we can't
769 pretend there's a static mapping here.
770 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
771 function to get the register name. That ought to be accurate.
772 However, we're changing a compile-time dependency (using the
773 REGISTER_NAMES macro) into a link- and run-time dependency
774 (calling REGISTER_NAME, which happens to be a function call on the
777 1999-01-22 Jim Lemke <jlemke@cygnus.com>

784 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

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

834 * configure: Regenerate.
835 * emul_{netbsd,unix}.c (toplevel): No longer try to include
836 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
838 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
840 * Makefile.in: The run target depended on a target psim$(EXEEXT),
841 but there was no such target, only plain psim. So I changed the
842 run target to depend on psim.
844 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
846 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
847 now defined in ../common/aclocal.m4, and the double definition causes
848 problems with AC_SUBST of EXEEXT.

943 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,
945 * words.h: __int64 instead of long long for MSVC.

1250 determine the simulation speed by looking at the number of elapsed
1251 ticks recorded by the event queue.
1253 * psim.c (psim_write_register, psim_read_register): Force the cpu
1254 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1255 next cpu would be zero any way.
1257 * mon.c (mon_print_info): If possible, print the system cycle
1258 performance. This is an indication of the number of instructions
1261 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1263 * The code to allow an event queue to be updated during a signal
1264 was missing. For main.c, a cntrl-c simulation termination wasn't
1267 * The simulation would not correctly restart if an event requested
1268 that the simulation be halted.
1270 * psim.c (psim_options): Add hack to -i option to optionally
1271 include a level vis -i2.
1272 (psim_usage): Document.

1291 * gen-idecode.c (print_run_until_stop_body): Call
1292 event_queue_process_events to clear possibly pending events before
1293 starting a simulation run. Re-arange main loop so that simulator
1294 is correctly restarted when an event halts the simulation.

1320 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1321 to be initialized independant of the rest of the simulation
1322 initalization. Otherwize a trace option explictly set from gdb
1323 could be overridden by hw_trace.
1325 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1327 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1328 debug.c. It could be much simpler.
1330 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1370 the form <name>_is_<const> where it is a boolean field, generate
1371 the result of the expression instead of the expression its self.

1373 then generating corresponding definitions.
1375 * gen-icache.c (print_icache_struct): If there is no cache, do not
1376 output expressions in idecode.h file.
1378 * gen-icache.c (print_icache_body): Output them here.
1380 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1387 * The code that put values in and extracted values from the cache
1388 was too compilicated. The cache table did not allow values to be
1389 computed from cache entries. #defines could only be used when a
1390 cache was present, remove the restriction.
1392 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1393 scratch variable is defined when a cache entry is beinf
1394 filled. Change the definition of a COMPUTE variable to be defined
1395 when the cache entry is being used.
1396 * gen-icache.c: Update.
1398 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1407 * gen-semantics.c (print_c_semantic): Update use.
1408 * gen-idecode.c (print_jump_insn): Update use.
1409 * gen-icache.c (print_icache_function): Update use.
1411 * igen.c (main): Change 'R' option so that it does not force the
1414 * configure.in (enable-sim-icache): Clarify description. Make
1415 #define one of the defaults regardless of the cache. Probably
1416 should revamp and add a separate option.
1418 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1420 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
