529 (sim_io_poll_quit): Only call the poll_quit callback
530 after the specified POLL_QUIT_INTERVAL.

544 Make the simulator compatible with the MPC750. It would be nicer
545 to make this a real multi-sim, but that's more work than we have
546 time for.
547 * emul_generic.c (emul_add_tree_options): Only require strict
548 alignment if it was explicitly requested at configuration time.
549 Don't make it the default for little-endian machines.
550 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
551 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
552 THRM2, THRM3): Plop in the MPC750 SPR registers.
553 (DABR): This is weird. This was HID5, but the PPC spec says this
554 should be DABR; why did some random processor use it for something
555 else? The HID5 entry dates back to the original checkin of the
556 simulator code in 1995, so remove it.
557 * sim_calls.c (register_names): Delete this; since the user can
558 now change GDB's list of register names dynamically, we can't
559 pretend there's a static mapping here.
560 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
561 function to get the register name. That ought to be accurate.
562 However, we're changing a compile-time dependency (using the
563 REGISTER_NAMES macro) into a link- and run-time dependency
564 (calling REGISTER_NAME, which happens to be a function call on the
565 PPC).
566
5671999-01-22 Jim Lemke <jlemke@cygnus.com>
568
569 * igen.c(gen_semantics_[ch]): setup/use of new option

574 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

595 Infinities.
596
597Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
598
599 * table.c (table_open): For cygwin hosts, we need to use the
600 return value from the read routine as the number of bytes to
601 process. This apparently is due to text-mode vs binary-mode. If
602 the mounts are done text-mode, then the size returnedby fstat()
603 may be different than the number of bytes "read" in text mode.

629
630 * Makefile.in: The run target depended on a target psim$(EXEEXT),
631 but there was no such target, only plain psim. So I changed the
632 run target to depend on psim.
633
634Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
635
636 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
637 now defined in ../common/aclocal.m4, and the double definition causes

912 via an additional option.
913
914 * ld-decode.h, ld-decode.c (force_decode_gen_type): New function,
915 allow the type of generated table specified in the decode file to

937 * main.c ({cntrl_c,main}): Use RETSIGTYPE for signal return type,
938 don't assume void.
939 * sim_calls.c (sim_{ctrl_c,resume}): Ditto.
940
941 * Makefile.in (callback.o): Define HAVE_CONFIG_H, so callback.c
942 includes our config.h.
943
944Tue Feb 4 13:42:59 1997 Doug Evans <dje@canuck.cygnus.com>
945
946 * configure.in: Fix typo in test for callback.c.

961 (device_add_ihandle_runtime_property): Update.
962

968
969 * gen-icache.c (print_icache_extraction): Add a reason parameter.
970 Augment each extracted field with a comment citing the codes
971 origin. Should simplify tracking down incorrect cache
972 extractions.
973
974Tue Feb 4 17:44:51 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
975
976 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
977 works for normal and boolean table entries.
978
979 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
980 valid. Handle this just like *_{read,write}_register now handles

994 max iterations exceeded.
995
996 * gen-idecode.c: Re-work the table lookup code so that it assumes
997 that the entry is a leaf by default. Simplify the boolean table
998 entry code so that it involves a mask + test instead of shift +
999 shift + mask + test.
1000
1001 * gen-idecode.c: Correct generated igen body so that it no drops
1002 or doubles clock interrupts.
1003
1004
1005Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1031 fields.
1032
1033 * misc.c (name2i): Possibly abort if an invalid name is
1034 encountered.
1035 * ld-decode.c: Abort if the table type isn't found.

1040 determine the simulation speed by looking at the number of elapsed
1041 ticks recorded by the event queue.
1042
1043 * psim.c (psim_write_register, psim_read_register): Force the cpu
1044 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1045 next cpu would be zero any way.
1046
1047 * mon.c (mon_print_info): If possible, print the system cycle
1048 performance. This is an indication of the number of instructions
1049 per second.
1050
1051Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1052
1053 * The code to allow an event queue to be updated during a signal
1054 was missing. For main.c, a cntrl-c simulation termination wasn't
1055 handled cleanly.
1056
1057 * The simulation would not correctly restart if an event requested
1058 that the simulation be halted.
1059
1060 * psim.c (psim_options): Add hack to -i option to optionally
1061 include a level vis -i2.
1062 (psim_usage): Document.
1063
1064 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
1065 cntrl-c occures schedule an event to halt the simulation.
1066 (main): Catch CNTRL-C signals with the function cntrl_c.
1067
1068 * events.c (event_queue_process): Mask interrupts while
1069 manipulating the async event queue.
1070 (event_queue_init): Ditto.
1071 (event_queue_schedule_after_signal): Ditto.
1072
1073 * events.c (event_queue_process): Mark the event queue as being in
1074 the processing state when processing has started. Adjust code
1075 so that it is tolerant of halts.
1076 (event_queue_init): Start the event queue out with processing
1077 false.
1078 (event_queue_tick): Check that processing isn't still being
1079 performed.
1080
1081 * gen-idecode.c (print_run_until_stop_body): Call
1082 event_queue_process_events to clear possibly pending events before
1083 starting a simulation run. Re-arange main loop so that simulator
1084 is correctly restarted when an event halts the simulation.

1086 * psim.c (psim_halt): Handle an event halting the simulation.
1087 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1088 reworked idecode.
1089
1090Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1091
1092 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1093 RA. Based on instruction frequency stats, expand additional
1094 instructions.
1095 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1096
1097 * ppc-opcode-stupid: Move all but the basic table in -complex into
1098 here. Update to new format.
1099
1100 * Makefile.in (tmp-defines): New target. Force defines.h to always
1101 be built. Hence get ppc-opcode-goto to build.
1102
1103Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1104
1105 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1106 Implement.
1107
1108Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1109
1110 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1111 to be initialized independant of the rest of the simulation
1112 initalization. Otherwize a trace option explictly set from gdb
1113 could be overridden by hw_trace.
1114
1115 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1116
1117 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1118 debug.c. It could be much simpler.
1119
1120Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1121
1122 * Some devices support removable media. Add hooks to the disk
1123 device so that it supports this.
1124
1125 * device.c (device_add_string_array_property,
1126 device_find_string_array_property): New functions, manipulate
1127 properties containing an array of strings.

1133 media. If no file image is specified, use the next one in the
1134 image property list.
1135 (hw_disk_init_address): Change the file property so that it is a
1136 string array - use the first entry for the initial file image.
1137
1138 * tree.c (print_string_aray_property): New function - print a
1139 string array.
1140 (print_properties): Adjust.
1141 (print_string): Write a string, handling double quotes.
1142
1143 * device.h: Define an ioctl to `change-media' with an optional new
1144 media image.
1145
1146 * hw_disk.c: Allow floppy disk devices to be specified.
1147
1148 * psim.c (psim_command): New function, parse more complex psim
1149 commands such as "change-media" and "trace".
1150 * sim_calls.c (sim_do_command): Use.
1151
1152Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1153
1154 * For expressions like (RA == 0) that are entered in to the cache
1155 as RA_is_0. If possible generate the result of the expression so
1156 that the compiler gets a better chance of eliminating dead
1157 branches.
1158
1159 * gen-icache.c (print_icache_extraction): For a cache entry of
1160 the form <name>_is_<const> where it is a boolean field, generate
1161 the result of the expression instead of the expression its self.
1162 (print_icache_body): Remove code that was looking for *_is_0 and
1163 then generating corresponding definitions.
1164
1165 * gen-icache.c (print_icache_struct): If there is no cache, do not
1166 output expressions in idecode.h file.
1167
1168 * gen-icache.c (print_icache_body): Output them here.
1169
1170 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1171 expansion.

1174
1175Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1176
1177 * The code that put values in and extracted values from the cache
1178 was too compilicated. The cache table did not allow values to be
1179 computed from cache entries. #defines could only be used when a
1180 cache was present, remove the restriction.
1181
1182 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1183 scratch variable is defined when a cache entry is beinf
1184 filled. Change the definition of a COMPUTE variable to be defined
1185 when the cache entry is being used.
1186 * gen-icache.c: Update.
1187
1188 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1189 is more obvious. old_name->field_name, new_name->derived_name.
1190 * gen-icache.c: Update
1191
1192 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1193 different types of cache code - put into cache, extract from
1194 cache, no cache - an explicit argument to print_icache_body.
1195 * gen-icache.c (print_icache_extraction): Ditto.
1196
1197 * gen-semantics.c (print_c_semantic): Update use.
1198 * gen-idecode.c (print_jump_insn): Update use.
1199 * gen-icache.c (print_icache_function): Update use.
1200
1201 * igen.c (main): Change 'R' option so that it does not force the
1202 cache.
1203
1204 * configure.in (enable-sim-icache): Clarify description. Make
1205 #define one of the defaults regardless of the cache. Probably
1206 should revamp and add a separate option.
1207
1208Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1209
1210 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
1211 partition numbering.

1213 1..3.
1214 (is_iso9660): New function, verify a CD9660 File system.
1215 (pk_disklabel_create_instance): Start expanding so that active
1216 partition selection is supported.

1218Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1219
1220 * The cap object was retaining a reference to the instance of a
1221 device after it was deleted. Instead add and remove cap's from the
1222 cap db as they are created and deleted. This ensuring that a
1223 capibility is only used during the lifetime of the corresponding
1224 object.
1225
1226 * cap.h, cap.c: Correct cap type - was signed32 should be
1227 signed_cell.
1228
1229 * cap.c (cap_add, cap_remove): New methods for cap object that
1230 allow the explicit addition and removal of internal objects that
1231 the cap knows about.
1232
1233 * cap.c (cap_init): Rewrite. Verify that the only objects
1234 remaining in the cap data base are those that were entered first.
1235 Thse objects will be the permenant ones.
1236 * device.c (device_init_address): Remember to initialize the cap
1237 database.
1238
1239 * device.c (device_create_instance_from): Explicitly add device
1240 instances to the cap database. Simplify create code.
1241 (device_instance_delete): Explicitly remove device instances from

1257Sun Jan 19 15:28:23 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1258
1259 * The memory "claim" and "release" methods take an address and
1260 size as arguments. These may be multi cell values. Initially fix
1261 the memory code so that they check/detect this. Leave the
1262 adjustment of any clients to later.
1263
1264 * hw_memory.c (hw_memory_instance_claim,
1265 hw_memory_instance_release): Handle multi-cell memory devices.
1266
1267 * hw_memory.c (hw_memory_instance_claim): Be tolerant towards the

1269
1270Fri Jan 17 12:01:07 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1271
1272 * device.h, device.c (device_instance_call_method): Correct return
1273 type - can return either 0 or -1, hence should be a signed type.
1274 * device_table.h: Ditto.
1275
1276 * hw_memory.c (hw_memory_instance_claim,
1277 hw_memory_instance_release): Update.

1284 method belonging to "/chosen/memory".
1285 (chirm_emul_release): Ditto.
1286
1287 * Makefile.in (LIB_INLINE_SRC): Remove emul_* from list of files
1288 that are inlined. These modules are called via a table and are
1289 not made inline.
1290
1291 * hw_init.c (update_for_binary_section): Fix failure to allocate
1292 memory used by the binary in real-mode executions. If "claim"
1293 property is present, allocate memory from the "/chosen/memory"
1294 device.
1295
1296 * emul_chirp.c (emul_chirp_create): Specify that memory should be
1297 claimed when loading a real image.
