561 after the specified POLL_QUIT_INTERVAL.

574
575 Make the simulator compatible with the MPC750. It would be nicer
576 to make this a real multi-sim, but that's more work than we have
577 time for.
578 * emul_generic.c (emul_add_tree_options): Only require strict
579 alignment if it was explicitly requested at configuration time.
580 Don't make it the default for little-endian machines.
581 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
582 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
583 THRM2, THRM3): Plop in the MPC750 SPR registers.
584 (DABR): This is weird. This was HID5, but the PPC spec says this
585 should be DABR; why did some random processor use it for something
586 else? The HID5 entry dates back to the original checkin of the
587 simulator code in 1995, so remove it.
588 * sim_calls.c (register_names): Delete this; since the user can
589 now change GDB's list of register names dynamically, we can't
590 pretend there's a static mapping here.
591 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
592 function to get the register name. That ought to be accurate.
593 However, we're changing a compile-time dependency (using the
594 REGISTER_NAMES macro) into a link- and run-time dependency
595 (calling REGISTER_NAME, which happens to be a function call on the
596 PPC).
597
5981999-01-22 Jim Lemke <jlemke@cygnus.com>
599
600 * igen.c(gen_semantics_[ch]): setup/use of new option

604 psim.c(is_num - added, psim_options): Parse and init new option.
605 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

626 Infinities.
627
628Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
629
630 * table.c (table_open): For cygwin hosts, we need to use the
631 return value from the read routine as the number of bytes to
632 process. This apparently is due to text-mode vs binary-mode. If
633 the mounts are done text-mode, then the size returnedby fstat()
634 may be different than the number of bytes "read" in text mode.
635
636Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>

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

970 * sim_calls.c (sim_{ctrl_c,resume}): Ditto.
971
972 * Makefile.in (callback.o): Define HAVE_CONFIG_H, so callback.c
973 includes our config.h.
974
975Tue Feb 4 13:42:59 1997 Doug Evans <dje@canuck.cygnus.com>
976
977 * configure.in: Fix typo in test for callback.c.

999
1000 * gen-icache.c (print_icache_extraction): Add a reason parameter.
1001 Augment each extracted field with a comment citing the codes
1002 origin. Should simplify tracking down incorrect cache
1003 extractions.
1004
1005Tue Feb 4 17:44:51 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1006
1007 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1008 works for normal and boolean table entries.
1009
1010 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
1011 valid. Handle this just like *_{read,write}_register now handles

1026
1027 * gen-idecode.c: Re-work the table lookup code so that it assumes
1028 that the entry is a leaf by default. Simplify the boolean table
1029 entry code so that it involves a mask + test instead of shift +
1030 shift + mask + test.
1031
1032 * gen-idecode.c: Correct generated igen body so that it no drops
1033 or doubles clock interrupts.
1034

1062 fields.
1063
1064 * misc.c (name2i): Possibly abort if an invalid name is
1065 encountered.
1066 * ld-decode.c: Abort if the table type isn't found.

1073
1074 * psim.c (psim_write_register, psim_read_register): Force the cpu
1075 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1076 next cpu would be zero any way.
1077
1078 * mon.c (mon_print_info): If possible, print the system cycle
1079 performance. This is an indication of the number of instructions
1080 per second.
1081
1082Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1083
1084 * The code to allow an event queue to be updated during a signal
1085 was missing. For main.c, a cntrl-c simulation termination wasn't
1086 handled cleanly.
1087
1088 * The simulation would not correctly restart if an event requested
1089 that the simulation be halted.
1090
1091 * psim.c (psim_options): Add hack to -i option to optionally
1092 include a level vis -i2.
1093 (psim_usage): Document.
1094
1095 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
1096 cntrl-c occures schedule an event to halt the simulation.
1097 (main): Catch CNTRL-C signals with the function cntrl_c.
1098
1099 * events.c (event_queue_process): Mask interrupts while
1100 manipulating the async event queue.
1101 (event_queue_init): Ditto.
1102 (event_queue_schedule_after_signal): Ditto.
1103
1104 * events.c (event_queue_process): Mark the event queue as being in
1105 the processing state when processing has started. Adjust code
1106 so that it is tolerant of halts.
1107 (event_queue_init): Start the event queue out with processing
1108 false.
1109 (event_queue_tick): Check that processing isn't still being
1110 performed.
1111
1112 * gen-idecode.c (print_run_until_stop_body): Call
1113 event_queue_process_events to clear possibly pending events before
1114 starting a simulation run. Re-arange main loop so that simulator
1115 is correctly restarted when an event halts the simulation.

1117 * psim.c (psim_halt): Handle an event halting the simulation.
1118 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1119 reworked idecode.
1120
1121Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1122
1123 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1124 RA. Based on instruction frequency stats, expand additional
1125 instructions.
1126 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1127
1128 * ppc-opcode-stupid: Move all but the basic table in -complex into
1129 here. Update to new format.
1130
1131 * Makefile.in (tmp-defines): New target. Force defines.h to always
1132 be built. Hence get ppc-opcode-goto to build.
1133
1134Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1135
1136 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1137 Implement.
1138
1139Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1140
1141 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1142 to be initialized independant of the rest of the simulation
1143 initalization. Otherwize a trace option explictly set from gdb
1144 could be overridden by hw_trace.
1145
1146 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1147
1148 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1149 debug.c. It could be much simpler.
1150
1151Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1152
1153 * Some devices support removable media. Add hooks to the disk
1154 device so that it supports this.

1164 media. If no file image is specified, use the next one in the
1165 image property list.
1166 (hw_disk_init_address): Change the file property so that it is a
1167 string array - use the first entry for the initial file image.
1168
1169 * tree.c (print_string_aray_property): New function - print a
1170 string array.
1171 (print_properties): Adjust.
1172 (print_string): Write a string, handling double quotes.
1173
1174 * device.h: Define an ioctl to `change-media' with an optional new
1175 media image.
1176
1177 * hw_disk.c: Allow floppy disk devices to be specified.
1178
1179 * psim.c (psim_command): New function, parse more complex psim
1180 commands such as "change-media" and "trace".
1181 * sim_calls.c (sim_do_command): Use.
1182
1183Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1184
1185 * For expressions like (RA == 0) that are entered in to the cache
1186 as RA_is_0. If possible generate the result of the expression so
1187 that the compiler gets a better chance of eliminating dead
1188 branches.
1189
1190 * gen-icache.c (print_icache_extraction): For a cache entry of
1191 the form <name>_is_<const> where it is a boolean field, generate
1192 the result of the expression instead of the expression its self.
1193 (print_icache_body): Remove code that was looking for *_is_0 and
1194 then generating corresponding definitions.
1195
1196 * gen-icache.c (print_icache_struct): If there is no cache, do not
1197 output expressions in idecode.h file.
1198
1199 * gen-icache.c (print_icache_body): Output them here.
1200
1201 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1202 expansion.

1205
1206Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1207
1208 * The code that put values in and extracted values from the cache
1209 was too compilicated. The cache table did not allow values to be
1210 computed from cache entries. #defines could only be used when a
1211 cache was present, remove the restriction.
1212
1213 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1214 scratch variable is defined when a cache entry is beinf
1215 filled. Change the definition of a COMPUTE variable to be defined
1216 when the cache entry is being used.
1217 * gen-icache.c: Update.
1218
1219 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1220 is more obvious. old_name->field_name, new_name->derived_name.
1221 * gen-icache.c: Update
1222
1223 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1224 different types of cache code - put into cache, extract from
1225 cache, no cache - an explicit argument to print_icache_body.
1226 * gen-icache.c (print_icache_extraction): Ditto.
1227
1228 * gen-semantics.c (print_c_semantic): Update use.
1229 * gen-idecode.c (print_jump_insn): Update use.
1230 * gen-icache.c (print_icache_function): Update use.
1231
1232 * igen.c (main): Change 'R' option so that it does not force the
1233 cache.
1234
1235 * configure.in (enable-sim-icache): Clarify description. Make
1236 #define one of the defaults regardless of the cache. Probably
1237 should revamp and add a separate option.
1238
1239Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1240
1241 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
1242 partition numbering.

1244 1..3.
1245 (is_iso9660): New function, verify a CD9660 File system.
1246 (pk_disklabel_create_instance): Start expanding so that active
1247 partition selection is supported.

1249Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1250
1251 * The cap object was retaining a reference to the instance of a
1252 device after it was deleted. Instead add and remove cap's from the
1253 cap db as they are created and deleted. This ensuring that a
1254 capibility is only used during the lifetime of the corresponding
1255 object.
1256
1257 * cap.h, cap.c: Correct cap type - was signed32 should be
1258 signed_cell.
1259
1260 * cap.c (cap_add, cap_remove): New methods for cap object that
1261 allow the explicit addition and removal of internal objects that
1262 the cap knows about.
1263
1264 * cap.c (cap_init): Rewrite. Verify that the only objects
1265 remaining in the cap data base are those that were entered first.
1266 Thse objects will be the permenant ones.
1267 * device.c (device_init_address): Remember to initialize the cap
1268 database.
1269
1270 * device.c (device_create_instance_from): Explicitly add device
1271 instances to the cap database. Simplify create code.
1272 (device_instance_delete): Explicitly remove device instances from

1287
1288Sun Jan 19 15:28:23 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1289
1290 * The memory "claim" and "release" methods take an address and
1291 size as arguments. These may be multi cell values. Initially fix
1292 the memory code so that they check/detect this. Leave the
1293 adjustment of any clients to later.
1294
1295 * hw_memory.c (hw_memory_instance_claim,
1296 hw_memory_instance_release): Handle multi-cell memory devices.
1297
1298 * hw_memory.c (hw_memory_instance_claim): Be tolerant towards the

1300
1301Fri Jan 17 12:01:07 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1302
