559 after the specified POLL_QUIT_INTERVAL.

572
573 Make the simulator compatible with the MPC750. It would be nicer
574 to make this a real multi-sim, but that's more work than we have
575 time for.
576 * emul_generic.c (emul_add_tree_options): Only require strict
577 alignment if it was explicitly requested at configuration time.
578 Don't make it the default for little-endian machines.
579 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
580 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
581 THRM2, THRM3): Plop in the MPC750 SPR registers.
582 (DABR): This is weird. This was HID5, but the PPC spec says this
583 should be DABR; why did some random processor use it for something
584 else? The HID5 entry dates back to the original checkin of the
585 simulator code in 1995, so remove it.
586 * sim_calls.c (register_names): Delete this; since the user can
587 now change GDB's list of register names dynamically, we can't
588 pretend there's a static mapping here.
589 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
590 function to get the register name. That ought to be accurate.
591 However, we're changing a compile-time dependency (using the
592 REGISTER_NAMES macro) into a link- and run-time dependency
593 (calling REGISTER_NAME, which happens to be a function call on the
594 PPC).
595
5961999-01-22 Jim Lemke <jlemke@cygnus.com>
597
598 * igen.c(gen_semantics_[ch]): setup/use of new option
599 (-o mpc860c0[=n]).

601 ppc-instructions(the four branch insn groups): detect problematic br's.
602 psim.c(is_num - added, psim_options): Parse and init new option.
603 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
604

618 poll the external environment.

621
622 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
623 fractional type, so that quiet NaN's aren't treated like
624 Infinities.
625
626Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
627
628 * table.c (table_open): For cygwin hosts, we need to use the
629 return value from the read routine as the number of bytes to
630 process. This apparently is due to text-mode vs binary-mode. If
631 the mounts are done text-mode, then the size returnedby fstat()
632 may be different than the number of bytes "read" in text mode.
633
634Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
635
636 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

658
659 * Makefile.in: The run target depended on a target psim$(EXEEXT),
660 but there was no such target, only plain psim. So I changed the
661 run target to depend on psim.
662
663Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
664
665 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
666 now defined in ../common/aclocal.m4, and the double definition causes
667 problems with AC_SUBST of EXEEXT.

968 * sim_calls.c (sim_{ctrl_c,resume}): Ditto.
969
970 * Makefile.in (callback.o): Define HAVE_CONFIG_H, so callback.c

972
973Tue Feb 4 13:42:59 1997 Doug Evans <dje@canuck.cygnus.com>
974
975 * configure.in: Fix typo in test for callback.c.

997
998 * gen-icache.c (print_icache_extraction): Add a reason parameter.
999 Augment each extracted field with a comment citing the codes
1000 origin. Should simplify tracking down incorrect cache
1001 extractions.
1002
1003Tue Feb 4 17:44:51 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1004

1006 works for normal and boolean table entries.
1007
1008 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now

1024
1025 * gen-idecode.c: Re-work the table lookup code so that it assumes
1026 that the entry is a leaf by default. Simplify the boolean table
1027 entry code so that it involves a mask + test instead of shift +
1028 shift + mask + test.
1029
1030 * gen-idecode.c: Correct generated igen body so that it no drops
1031 or doubles clock interrupts.
1032

1060 fields.
1061
1062 * misc.c (name2i): Possibly abort if an invalid name is
1063 encountered.
1064 * ld-decode.c: Abort if the table type isn't found.

1071
1072 * psim.c (psim_write_register, psim_read_register): Force the cpu
1073 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1074 next cpu would be zero any way.

1076 * mon.c (mon_print_info): If possible, print the system cycle
1077 performance. This is an indication of the number of instructions
1078 per second.
1079
1080Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1081
1082 * The code to allow an event queue to be updated during a signal
1083 was missing. For main.c, a cntrl-c simulation termination wasn't
1084 handled cleanly.
1085
1086 * The simulation would not correctly restart if an event requested
1087 that the simulation be halted.
1088
1089 * psim.c (psim_options): Add hack to -i option to optionally
1090 include a level vis -i2.
1091 (psim_usage): Document.
1092
1093 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
1094 cntrl-c occures schedule an event to halt the simulation.
1095 (main): Catch CNTRL-C signals with the function cntrl_c.
1096
1097 * events.c (event_queue_process): Mask interrupts while
1098 manipulating the async event queue.

1100 (event_queue_schedule_after_signal): Ditto.
1101
1102 * events.c (event_queue_process): Mark the event queue as being in
1103 the processing state when processing has started. Adjust code
1104 so that it is tolerant of halts.
1105 (event_queue_init): Start the event queue out with processing
1106 false.
1107 (event_queue_tick): Check that processing isn't still being
1108 performed.
1109
1110 * gen-idecode.c (print_run_until_stop_body): Call
1111 event_queue_process_events to clear possibly pending events before
1112 starting a simulation run. Re-arange main loop so that simulator
1113 is correctly restarted when an event halts the simulation.

1115 * psim.c (psim_halt): Handle an event halting the simulation.
1116 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1117 reworked idecode.
1118
1119Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1120
1121 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1122 RA. Based on instruction frequency stats, expand additional
1123 instructions.
1124 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1125
1126 * ppc-opcode-stupid: Move all but the basic table in -complex into
1127 here. Update to new format.
1128
1129 * Makefile.in (tmp-defines): New target. Force defines.h to always
1130 be built. Hence get ppc-opcode-goto to build.
1131
1132Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1133
1134 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1135 Implement.
1136
1137Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1138
1139 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1140 to be initialized independant of the rest of the simulation
1141 initalization. Otherwize a trace option explictly set from gdb
1142 could be overridden by hw_trace.
1143
1144 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1145
1146 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1147 debug.c. It could be much simpler.
1148
1149Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1150
1151 * Some devices support removable media. Add hooks to the disk

1162 media. If no file image is specified, use the next one in the
1163 image property list.
1164 (hw_disk_init_address): Change the file property so that it is a
1165 string array - use the first entry for the initial file image.
1166
1167 * tree.c (print_string_aray_property): New function - print a
1168 string array.
1169 (print_properties): Adjust.
1170 (print_string): Write a string, handling double quotes.
1171

1173 media image.
1174
1175 * hw_disk.c: Allow floppy disk devices to be specified.
1176
1177 * psim.c (psim_command): New function, parse more complex psim
1178 commands such as "change-media" and "trace".

1180
1181Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1182
1183 * For expressions like (RA == 0) that are entered in to the cache
1184 as RA_is_0. If possible generate the result of the expression so
1185 that the compiler gets a better chance of eliminating dead
1186 branches.
1187
1188 * gen-icache.c (print_icache_extraction): For a cache entry of
1189 the form <name>_is_<const> where it is a boolean field, generate
1190 the result of the expression instead of the expression its self.
1191 (print_icache_body): Remove code that was looking for *_is_0 and
1192 then generating corresponding definitions.
1193
1194 * gen-icache.c (print_icache_struct): If there is no cache, do not
1195 output expressions in idecode.h file.
1196
1197 * gen-icache.c (print_icache_body): Output them here.
1198
1199 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1200 expansion.

1203
1204Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1205
1206 * The code that put values in and extracted values from the cache
1207 was too compilicated. The cache table did not allow values to be
1208 computed from cache entries. #defines could only be used when a
1209 cache was present, remove the restriction.
1210
1211 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1212 scratch variable is defined when a cache entry is beinf
1213 filled. Change the definition of a COMPUTE variable to be defined
1214 when the cache entry is being used.
1215 * gen-icache.c: Update.
1216
1217 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1218 is more obvious. old_name->field_name, new_name->derived_name.
1219 * gen-icache.c: Update
1220
1221 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1222 different types of cache code - put into cache, extract from
1223 cache, no cache - an explicit argument to print_icache_body.
1224 * gen-icache.c (print_icache_extraction): Ditto.
1225
1226 * gen-semantics.c (print_c_semantic): Update use.
1227 * gen-idecode.c (print_jump_insn): Update use.
1228 * gen-icache.c (print_icache_function): Update use.
1229
1230 * igen.c (main): Change 'R' option so that it does not force the
1231 cache.
1232
1233 * configure.in (enable-sim-icache): Clarify description. Make
1234 #define one of the defaults regardless of the cache. Probably
1235 should revamp and add a separate option.
1236
1237Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1238
1239 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
1240 partition numbering.

1242 1..3.
1243 (is_iso9660): New function, verify a CD9660 File system.
1244 (pk_disklabel_create_instance): Start expanding so that active
1245 partition selection is supported.

1247Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1248
1249 * The cap object was retaining a reference to the instance of a
1250 device after it was deleted. Instead add and remove cap's from the
1251 cap db as they are created and deleted. This ensuring that a
1252 capibility is only used during the lifetime of the corresponding
1253 object.
1254
1255 * cap.h, cap.c: Correct cap type - was signed32 should be
1256 signed_cell.
1257
1258 * cap.c (cap_add, cap_remove): New methods for cap object that
1259 allow the explicit addition and removal of internal objects that
1260 the cap knows about.
1261
1262 * cap.c (cap_init): Rewrite. Verify that the only objects
1263 remaining in the cap data base are those that were entered first.
1264 Thse objects will be the permenant ones.
1265 * device.c (device_init_address): Remember to initialize the cap
1266 database.
1267
1268 * device.c (device_create_instance_from): Explicitly add device
1269 instances to the cap database. Simplify create code.

1286Sun Jan 19 15:28:23 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1287
1288 * The memory "claim" and "release" methods take an address and
1289 size as arguments. These may be multi cell values. Initially fix
1290 the memory code so that they check/detect this. Leave the
1291 adjustment of any clients to later.
1292
1293 * hw_memory.c (hw_memory_instance_claim,
1294 hw_memory_instance_release): Handle multi-cell memory devices.
1295
1296 * hw_memory.c (hw_memory_instance_claim): Be tolerant towards the

1298
1299Fri Jan 17 12:01:07 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1300
1301 * device.h, device.c (device_instance_call_method): Correct return
1302 type - can return either 0 or -1, hence should be a signed type.
