651 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
653 * sim-endian.h: Don't have parameters on macro definitions which
654 are simply renaming functions, to permit use of XCONCAT2 in both
655 the macro name and the arguments in a use of such a definition.
657 2000-11-15 Jim Blandy <jimb@redhat.com>
659 * sim_calls.c: Doc fix.
660 (sim_fetch_register, sim_store_register): Call

695 1999-05-08 Felix Lee <flee@cygnus.com>
697 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
698 * configure: Regenerated to track ../common/aclocal.m4 changes.
700 1999-04-02 Keith Seitz <keiths@cygnus.com>

708 1999-02-22 Jim Lemke <jlemke@cygnus.com>
710 * dc-complex: Force expansion on all bits of field BO.

718 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
720 Make the simulator compatible with the MPC750. It would be nicer
721 to make this a real multi-sim, but that's more work than we have
723 * emul_generic.c (emul_add_tree_options): Only require strict
724 alignment if it was explicitly requested at configuration time.
725 Don't make it the default for little-endian machines.
726 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
727 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
728 THRM2, THRM3): Plop in the MPC750 SPR registers.
729 (DABR): This is weird. This was HID5, but the PPC spec says this
730 should be DABR; why did some random processor use it for something
731 else? The HID5 entry dates back to the original checkin of the
732 simulator code in 1995, so remove it.
733 * sim_calls.c (register_names): Delete this; since the user can
734 now change GDB's list of register names dynamically, we can't
735 pretend there's a static mapping here.
736 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
737 function to get the register name. That ought to be accurate.
738 However, we're changing a compile-time dependency (using the
739 REGISTER_NAMES macro) into a link- and run-time dependency
740 (calling REGISTER_NAME, which happens to be a function call on the
743 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

1152 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1153 works for normal and boolean table entries.
1155 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
1156 valid. Handle this just like *_{read,write}_register now handles

1177 * gen-idecode.c: Correct generated igen body so that it no drops
1178 or doubles clock interrupts.
1181 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1183 * Makefile.in (BUILT_SRC_WO_CONFIG): Change targ-vals.* to

1213 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1215 * When performance monitoring is disabled, it is still possible to
1216 determine the simulation speed by looking at the number of elapsed
1217 ticks recorded by the event queue.
1219 * psim.c (psim_write_register, psim_read_register): Force the cpu
1220 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1221 next cpu would be zero any way.
1223 * mon.c (mon_print_info): If possible, print the system cycle
1224 performance. This is an indication of the number of instructions
1227 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1229 * The code to allow an event queue to be updated during a signal
1230 was missing. For main.c, a cntrl-c simulation termination wasn't
1233 * The simulation would not correctly restart if an event requested
1234 that the simulation be halted.
1236 * psim.c (psim_options): Add hack to -i option to optionally
1237 include a level vis -i2.
1238 (psim_usage): Document.
1240 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

1254 (event_queue_tick): Check that processing isn't still being
1257 * gen-idecode.c (print_run_until_stop_body): Call
1258 event_queue_process_events to clear possibly pending events before
1259 starting a simulation run. Re-arange main loop so that simulator
1260 is correctly restarted when an event halts the simulation.
1262 * psim.c (psim_halt): Handle an event halting the simulation.
1263 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1266 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1268 * ppc-opcode-complex: Correct typo - was expanding ORA instead of

1284 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1286 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1287 to be initialized independant of the rest of the simulation
1288 initalization. Otherwize a trace option explictly set from gdb
1289 could be overridden by hw_trace.
1291 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1293 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1294 debug.c. It could be much simpler.
1296 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1310 image property list.
1311 (hw_disk_init_address): Change the file property so that it is a
1312 string array - use the first entry for the initial file image.
1314 * tree.c (print_string_aray_property): New function - print a
1316 (print_properties): Adjust.

1335 * gen-icache.c (print_icache_extraction): For a cache entry of
1336 the form <name>_is_<const> where it is a boolean field, generate
1337 the result of the expression instead of the expression its self.

1339 then generating corresponding definitions.
1341 * gen-icache.c (print_icache_struct): If there is no cache, do not
1342 output expressions in idecode.h file.
1344 * gen-icache.c (print_icache_body): Output them here.
1346 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1351 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1353 * The code that put values in and extracted values from the cache
1354 was too compilicated. The cache table did not allow values to be
1355 computed from cache entries. #defines could only be used when a
1356 cache was present, remove the restriction.
1358 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1359 scratch variable is defined when a cache entry is beinf
1360 filled. Change the definition of a COMPUTE variable to be defined
1361 when the cache entry is being used.
1362 * gen-icache.c: Update.
1364 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1365 is more obvious. old_name->field_name, new_name->derived_name.
1366 * gen-icache.c: Update
1368 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1369 different types of cache code - put into cache, extract from
1370 cache, no cache - an explicit argument to print_icache_body.

1373 * gen-semantics.c (print_c_semantic): Update use.
1374 * gen-idecode.c (print_jump_insn): Update use.
1375 * gen-icache.c (print_icache_function): Update use.
1377 * igen.c (main): Change 'R' option so that it does not force the
1380 * configure.in (enable-sim-icache): Clarify description. Make
1381 #define one of the defaults regardless of the cache. Probably
1382 should revamp and add a separate option.
1384 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1386 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1405 * cap.c (cap_add, cap_remove): New methods for cap object that
1406 allow the explicit addition and removal of internal objects that
1407 the cap knows about.

1410 remaining in the cap data base are those that were entered first.
1411 Thse objects will be the permenant ones.
1412 * device.c (device_init_address): Remember to initialize the cap
1415 * device.c (device_create_instance_from): Explicitly add device
1416 instances to the cap database. Simplify create code.
