673 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
675 * sim-endian.h: Don't have parameters on macro definitions which
676 are simply renaming functions, to permit use of XCONCAT2 in both
677 the macro name and the arguments in a use of such a definition.
679 2000-11-15 Jim Blandy <jimb@redhat.com>
681 * sim_calls.c: Doc fix.
682 (sim_fetch_register, sim_store_register): Call

713 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
715 * configure: Regenerated to track ../common/aclocal.m4 changes.
717 1999-05-08 Felix Lee <flee@cygnus.com>
719 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
720 * configure: Regenerated to track ../common/aclocal.m4 changes.
722 1999-04-02 Keith Seitz <keiths@cygnus.com>

728 after the specified POLL_QUIT_INTERVAL.
730 1999-02-22 Jim Lemke <jlemke@cygnus.com>
732 * dc-complex: Force expansion on all bits of field BO.
733 Previously, the least-significant (prediction) bit was ignored.
734 * ppc-instructions (conditional branches): Implement mpc860c0 option.

740 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
742 Make the simulator compatible with the MPC750. It would be nicer
743 to make this a real multi-sim, but that's more work than we have
745 * emul_generic.c (emul_add_tree_options): Only require strict
746 alignment if it was explicitly requested at configuration time.
747 Don't make it the default for little-endian machines.
748 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
749 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
750 THRM2, THRM3): Plop in the MPC750 SPR registers.
751 (DABR): This is weird. This was HID5, but the PPC spec says this
752 should be DABR; why did some random processor use it for something
753 else? The HID5 entry dates back to the original checkin of the
754 simulator code in 1995, so remove it.
755 * sim_calls.c (register_names): Delete this; since the user can
756 now change GDB's list of register names dynamically, we can't
757 pretend there's a static mapping here.
758 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
759 function to get the register name. That ought to be accurate.
760 However, we're changing a compile-time dependency (using the
761 REGISTER_NAMES macro) into a link- and run-time dependency
762 (calling REGISTER_NAME, which happens to be a function call on the
765 1999-01-22 Jim Lemke <jlemke@cygnus.com>
767 * igen.c(gen_semantics_[ch]): setup/use of new option

771 psim.c(is_num - added, psim_options): Parse and init new option.
772 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
774 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
776 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

787 poll the external environment.
789 1998-11-19 Michael Meissner <meissner@cygnus.com>
791 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
792 fractional type, so that quiet NaN's aren't treated like
795 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
797 * table.c (table_open): For cygwin hosts, we need to use the
798 return value from the read routine as the number of bytes to
799 process. This apparently is due to text-mode vs binary-mode. If
800 the mounts are done text-mode, then the size returnedby fstat()
801 may be different than the number of bytes "read" in text mode.
803 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
805 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

817 return zero when nothing to do.
819 1998-06-26 Michael Meissner <meissner@cygnus.com>
821 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
822 * configure: Regenerate.
823 * emul_{netbsd,unix}.c (toplevel): No longer try to include
824 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
826 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
828 * Makefile.in: The run target depended on a target psim$(EXEEXT),
829 but there was no such target, only plain psim. So I changed the
830 run target to depend on psim.
832 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
834 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
835 now defined in ../common/aclocal.m4, and the double definition causes
836 problems with AC_SUBST of EXEEXT.

1175 works for normal and boolean table entries.
1177 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now

1238 determine the simulation speed by looking at the number of elapsed
1239 ticks recorded by the event queue.
1241 * psim.c (psim_write_register, psim_read_register): Force the cpu
1242 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1243 next cpu would be zero any way.
1245 * mon.c (mon_print_info): If possible, print the system cycle
1246 performance. This is an indication of the number of instructions
1249 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1251 * The code to allow an event queue to be updated during a signal
1252 was missing. For main.c, a cntrl-c simulation termination wasn't
1255 * The simulation would not correctly restart if an event requested
1256 that the simulation be halted.
1258 * psim.c (psim_options): Add hack to -i option to optionally
1259 include a level vis -i2.
1260 (psim_usage): Document.

1279 * gen-idecode.c (print_run_until_stop_body): Call
1280 event_queue_process_events to clear possibly pending events before
1281 starting a simulation run. Re-arange main loop so that simulator
1282 is correctly restarted when an event halts the simulation.

1308 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1309 to be initialized independant of the rest of the simulation
1310 initalization. Otherwize a trace option explictly set from gdb
1311 could be overridden by hw_trace.
1313 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1315 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1316 debug.c. It could be much simpler.
1318 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1334 string array - use the first entry for the initial file image.
1336 * tree.c (print_string_aray_property): New function - print a

1358 the form <name>_is_<const> where it is a boolean field, generate
1359 the result of the expression instead of the expression its self.

1361 then generating corresponding definitions.
1363 * gen-icache.c (print_icache_struct): If there is no cache, do not
1364 output expressions in idecode.h file.
1366 * gen-icache.c (print_icache_body): Output them here.
1368 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1375 * The code that put values in and extracted values from the cache
1376 was too compilicated. The cache table did not allow values to be
1377 computed from cache entries. #defines could only be used when a
1378 cache was present, remove the restriction.
1380 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1381 scratch variable is defined when a cache entry is beinf
1382 filled. Change the definition of a COMPUTE variable to be defined
1383 when the cache entry is being used.
1384 * gen-icache.c: Update.
1386 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1395 * gen-semantics.c (print_c_semantic): Update use.
1396 * gen-idecode.c (print_jump_insn): Update use.
1397 * gen-icache.c (print_icache_function): Update use.
1399 * igen.c (main): Change 'R' option so that it does not force the
1402 * configure.in (enable-sim-icache): Clarify description. Make
1403 #define one of the defaults regardless of the cache. Probably
1404 should revamp and add a separate option.
1406 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1408 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
