632 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
634 * sim-endian.h: Don't have parameters on macro definitions which
635 are simply renaming functions, to permit use of XCONCAT2 in both
636 the macro name and the arguments in a use of such a definition.
638 2000-11-15 Jim Blandy <jimb@redhat.com>
640 * sim_calls.c: Doc fix.
641 (sim_fetch_register, sim_store_register): Call

676 1999-05-08 Felix Lee <flee@cygnus.com>
678 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
679 * configure: Regenerated to track ../common/aclocal.m4 changes.
681 1999-04-02 Keith Seitz <keiths@cygnus.com>

699 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
701 Make the simulator compatible with the MPC750. It would be nicer
702 to make this a real multi-sim, but that's more work than we have
704 * emul_generic.c (emul_add_tree_options): Only require strict
705 alignment if it was explicitly requested at configuration time.
706 Don't make it the default for little-endian machines.
707 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
708 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
709 THRM2, THRM3): Plop in the MPC750 SPR registers.
710 (DABR): This is weird. This was HID5, but the PPC spec says this
711 should be DABR; why did some random processor use it for something
712 else? The HID5 entry dates back to the original checkin of the
713 simulator code in 1995, so remove it.
714 * sim_calls.c (register_names): Delete this; since the user can
715 now change GDB's list of register names dynamically, we can't
716 pretend there's a static mapping here.
717 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
718 function to get the register name. That ought to be accurate.
719 However, we're changing a compile-time dependency (using the
720 REGISTER_NAMES macro) into a link- and run-time dependency
721 (calling REGISTER_NAME, which happens to be a function call on the
724 1999-01-22 Jim Lemke <jlemke@cygnus.com>

751 fractional type, so that quiet NaN's aren't treated like
754 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
756 * table.c (table_open): For cygwin hosts, we need to use the
757 return value from the read routine as the number of bytes to
758 process. This apparently is due to text-mode vs binary-mode. If
759 the mounts are done text-mode, then the size returnedby fstat()
760 may be different than the number of bytes "read" in text mode.
762 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
764 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

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

1133 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1134 works for normal and boolean table entries.
1136 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now

1197 determine the simulation speed by looking at the number of elapsed
1198 ticks recorded by the event queue.
1200 * psim.c (psim_write_register, psim_read_register): Force the cpu
1201 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1202 next cpu would be zero any way.
1204 * mon.c (mon_print_info): If possible, print the system cycle
1205 performance. This is an indication of the number of instructions
1208 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1210 * The code to allow an event queue to be updated during a signal
1211 was missing. For main.c, a cntrl-c simulation termination wasn't
1214 * The simulation would not correctly restart if an event requested
1215 that the simulation be halted.
1217 * psim.c (psim_options): Add hack to -i option to optionally
1218 include a level vis -i2.
1219 (psim_usage): Document.

1238 * gen-idecode.c (print_run_until_stop_body): Call
1239 event_queue_process_events to clear possibly pending events before
1240 starting a simulation run. Re-arange main loop so that simulator
1241 is correctly restarted when an event halts the simulation.

1267 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1268 to be initialized independant of the rest of the simulation
1269 initalization. Otherwize a trace option explictly set from gdb
1270 could be overridden by hw_trace.
1272 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1274 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1275 debug.c. It could be much simpler.
1277 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1317 the form <name>_is_<const> where it is a boolean field, generate
1318 the result of the expression instead of the expression its self.

1320 then generating corresponding definitions.
1322 * gen-icache.c (print_icache_struct): If there is no cache, do not
1323 output expressions in idecode.h file.
1325 * gen-icache.c (print_icache_body): Output them here.
1327 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1334 * The code that put values in and extracted values from the cache
1335 was too compilicated. The cache table did not allow values to be
1336 computed from cache entries. #defines could only be used when a
1337 cache was present, remove the restriction.
1339 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1340 scratch variable is defined when a cache entry is beinf
1341 filled. Change the definition of a COMPUTE variable to be defined
1342 when the cache entry is being used.
1343 * gen-icache.c: Update.
1345 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1358 * igen.c (main): Change 'R' option so that it does not force the
1361 * configure.in (enable-sim-icache): Clarify description. Make
1362 #define one of the defaults regardless of the cache. Probably
1363 should revamp and add a separate option.

3764 * debug.h: Add trace_print_info, trace_print_device_tree and
3765 trace_dump_device_tree. The first is a replacement for the
3766 variable `print_info' found in main.c and sim_calls.c. The latter
3767 two enable the dumping of the entire device tree.

3824 * device.c (external_to_device) : New function that provides a
3825 standard mapping between a devices internal representation (a
3826 pointer) and its external (or what is passed to a client)
3827 representation (a phandle). Implement using the cap object
3828 attached to the root node.

3852 read/write calls for buffer transfers. This will cause a fault to
3853 occure if the transfer fails. CHRP catches the fault while the
3854 others suffer the consequences.
