 641 1999-02-01  Jim Blandy  <jimb@zwingli.cygnus.com>
 642
 643         Make the simulator compatible with the MPC750.  It would be nicer
 644         to make this a real multi-sim, but that's more work than we have
 645         time for.
 646         * emul_generic.c (emul_add_tree_options): Only require strict
 647         alignment if it was explicitly requested at configuration time.
 648         Don't make it the default for little-endian machines.
 649         * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
 650         MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
 651         THRM2, THRM3): Plop in the MPC750 SPR registers.
 652         (DABR): This is weird.  This was HID5, but the PPC spec says this
 653         should be DABR; why did some random processor use it for something
 654         else?  The HID5 entry dates back to the original checkin of the
 655         simulator code in 1995, so remove it.
 656         * sim_calls.c (register_names): Delete this; since the user can
 657         now change GDB's list of register names dynamically, we can't
 658         pretend there's a static mapping here.
 659         (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
 660         function to get the register name.  That ought to be accurate.
 661         However, we're changing a compile-time dependency (using the
 662         REGISTER_NAMES macro) into a link- and run-time dependency
 663         (calling REGISTER_NAME, which happens to be a function call on the
 664         PPC).

 672         psim.c(is_num - added, psim_options): Parse and init new option.

 701         the mounts are done text-mode, then the size returnedby fstat()
 702         may be different than the number of bytes "read" in text mode.

1054
1055         * Property create/initialization still wasn't correctly ordered.
1056         Should be delaying everything related to ihandle creation until
1057         after the rest of the tree has been established.
1058
1059         * device.c (device_find_ihandle_runtime_property): Update.
1060         (device_add_ihandle_runtime_property): Update.
1061
1062         * tree.c (parse_ihandle_property): Delay lookup of the device to
1063         be opened until the ihandle initialization phase.
1064         * tree.c (print_properties): Update.
1065
1066 Wed Feb  5 10:56:27 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1067
1068         * gen-icache.c (print_icache_extraction): Add a reason parameter.
1069         Augment each extracted field with a comment citing the codes
1070         origin.  Should simplify tracking down incorrect cache
1071         extractions.
1072
1073 Tue Feb  4 17:44:51 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1074
1075         * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1076         works for normal and boolean table entries.
1077
1078         * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
1079         valid.  Handle this just like *_{read,write}_register now handles
1080         it.
1081
1082 Mon Feb  3 17:18:16 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1083
1084         * events.c (insert_event_entry): Correct loop termination
1085         assertions.
1086
1087 Fri Jan 31 16:20:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1088
1089         * psim.c (psim_options): Add new option -c for max-iterations or
1090         count.
1091         (psim_usage): Document.
1092         (psim_max_iterations_exceeded): New function, abort simulation if
1093         max iterations exceeded.
1094
1095         * gen-idecode.c: Re-work the table lookup code so that it assumes
1096         that the entry is a leaf by default.  Simplify the boolean table
1097         entry code so that it involves a mask + test instead of shift +
1098         shift + mask + test.
1099
1100         * gen-idecode.c: Correct generated igen body so that it no drops
1101         or doubles clock interrupts.
1102
1103
1104 Thu Jan 30 11:23:20 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1105
1106         * Makefile.in (BUILT_SRC_WO_CONFIG): Change targ-vals.* to

1110         if common callback is present.
1111
1112 Wed Jan 29 12:32:41 1997  Michael Meissner  <meissner@tiktok.cygnus.com>
1113
1114         * configure.in (sim_callback): If the gdb is post 4.16, configure
1115         callback support from the common directory.
1116         * configure: Regenerate.
1117
1118         * Makefile.in (BUILT_SRC_WO_CONFIG): Add targ-vals.{h,def} and
1119         targ-map.c.
1120         (GDB_OBJ): Add callback support configured in.
1121         (gentmap,targ-vals.def): Build from common directory.
1122         (targ-vals.h,targ-map.c): Build by running gentmap.
1123         (callback.o): Build from source in common directory.
1124         (targ-map.o): Add dependency.
1125         (clean): Remove gentmap.
1126
1127 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1128
1129         * igen wasn't aborting if the opcode table contained no valid
1130         fields.
1131
1132         * misc.c (name2i): Possibly abort if an invalid name is
1133         encountered.
1134         * ld-decode.c: Abort if the table type isn't found.
1135
1136 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1137
1138         * When performance monitoring is disabled, it is still possible to
1139         determine the simulation speed by looking at the number of elapsed
1140         ticks recorded by the event queue.
1141
1142         * psim.c (psim_write_register, psim_read_register): Force the cpu
1143         to zero when it is either of `-1' or `nr_cpus'.  In both cases the
1144         next cpu would be zero any way.
1145
1146         * mon.c (mon_print_info): If possible, print the system cycle
1147         performance.  This is an indication of the number of instructions
1148         per second.
1149
1150 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1151
1152         * The code to allow an event queue to be updated during a signal
1153         was missing.  For main.c, a cntrl-c simulation termination wasn't
1154         handled cleanly.
1155
1156         * The simulation would not correctly restart if an event requested
1157         that the simulation be halted.
1158
1159         * psim.c (psim_options): Add hack to -i option to optionally
1160         include a level vis -i2.
1161         (psim_usage): Document.
1162
1163         * main.c (cntrl_c, cntrl_c_simulation): New functions.  When a
1164         cntrl-c occures schedule an event to halt the simulation.
1165         (main): Catch CNTRL-C signals with the function cntrl_c.
1166
1167         * events.c (event_queue_process): Mask interrupts while
1168         manipulating the async event queue.
1169         (event_queue_init): Ditto.
1170         (event_queue_schedule_after_signal): Ditto.
1171
1172         * events.c (event_queue_process): Mark the event queue as being in
1173         the processing state when processing has started.  Adjust code
1174         so that it is tolerant of halts.
1175         (event_queue_init): Start the event queue out with processing
1176         false.
1177         (event_queue_tick): Check that processing isn't still being
1178         performed.
1179
1180         * gen-idecode.c (print_run_until_stop_body): Call
1181         event_queue_process_events to clear possibly pending events before
1182         starting a simulation run.  Re-arange main loop so that simulator
1183         is correctly restarted when an event halts the simulation.
1184
1185         * psim.c (psim_halt): Handle an event halting the simulation.
1186         * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1187         reworked idecode.
1188
1189 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1190
1191         * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1192         RA.  Based on instruction frequency stats, expand additional
1193         instructions.
1194         * ppc-instructions: Change all `RA == 0' to RA_is_0.
1195
1196         * ppc-opcode-stupid: Move all but the basic table in -complex into
1197         here.  Update to new format.
1198
1199         * Makefile.in (tmp-defines): New target. Force defines.h to always
1200         be built.  Hence get ppc-opcode-goto to build.
1201
1202 Tue Jan 28 13:00:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1203
1204         * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1205         Implement.
1206
1207 Thu Jan 23 09:07:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1208
1209         * hw_trace.c (hw_trace_init_data): Delete.  The trace options need
1210         to be initialized independant of the rest of the simulation
1211         initalization.  Otherwize a trace option explictly set from gdb
1212         could be overridden by hw_trace.
1213
1214         * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1215
1216         * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1217         debug.c.  It could be much simpler.
1218
1219 Thu Jan 23 09:07:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1220
1221         * Some devices support removable media.  Add hooks to the disk
1222         device so that it supports this.
1223
1224         * device.c (device_add_string_array_property,
1225         device_find_string_array_property): New functions, manipulate
1226         properties containing an array of strings.
1227         (device_find_string_property): Allow a string array.
1228         (device_init_static_properties): Update.
1229         (device_init_runtime_properties): Update.
1230
1231         * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
1232         media.  If no file image is specified, use the next one in the
1233         image property list.
1234         (hw_disk_init_address): Change the file property so that it is a
1235         string array - use the first entry for the initial file image.
1236
1237         * tree.c (print_string_aray_property): New function - print a
1238         string array.
1239         (print_properties): Adjust.
1240         (print_string): Write a string, handling double quotes.
1241
1242         * device.h: Define an ioctl to `change-media' with an optional new
1243         media image.
1244
1245         * hw_disk.c: Allow floppy disk devices to be specified.
1246
1247         * psim.c (psim_command): New function, parse more complex psim
1248         commands such as "change-media" and "trace".
1249         * sim_calls.c (sim_do_command): Use.
1250
1251 Wed Jan 22 09:38:33 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1252
1253         * For expressions like (RA == 0) that are entered in to the cache
1254         as RA_is_0. If possible generate the result of the expression so
1255         that the compiler gets a better chance of eliminating dead
1256         branches.
1257
1258         * gen-icache.c (print_icache_extraction): For a cache entry of
1259         the form <name>_is_<const> where it is a boolean field, generate
1260         the result of the expression instead of the expression its self.
1261         (print_icache_body): Remove code that was looking for *_is_0 and
1262         then generating corresponding definitions.
1263
1264         * gen-icache.c (print_icache_struct): If there is no cache, do not
1265         output expressions in idecode.h file.
1266
1267         * gen-icache.c (print_icache_body): Output them here.
1268
1269         * ppc-opcode-complex: Clarify constant values for SPR==LR register
1270         expansion.
1271
1272         * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
1273
1274 Wed Jan 22 12:24:52 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1275
1276         * The code that put values in and extracted values from the cache
1277         was too compilicated.  The cache table did not allow values to be
1278         computed from cache entries.  #defines could only be used when a
1279         cache was present, remove the restriction.
1280
1281         * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH.  A
1282         scratch variable is defined when a cache entry is beinf
1283         filled. Change the definition of a COMPUTE variable to be defined
1284         when the cache entry is being used.
1285         * gen-icache.c: Update.
1286
1287         * ld-cache.h, ld-cache.c: Change field names so that their meaning
1288         is more obvious.  old_name->field_name, new_name->derived_name.
1289         * gen-icache.c: Update
1290
1291         * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1292         different types of cache code - put into cache, extract from
1293         cache, no cache - an explicit argument to print_icache_body.
1294         * gen-icache.c (print_icache_extraction): Ditto.
1295
1296         * gen-semantics.c (print_c_semantic): Update use.
1297         * gen-idecode.c (print_jump_insn): Update use.
1298         * gen-icache.c (print_icache_function): Update use.
1299
1300         * igen.c (main): Change 'R' option so that it does not force the
1301         cache.
1302
1303         * configure.in (enable-sim-icache): Clarify description.  Make
1304         #define one of the defaults regardless of the cache.  Probably
1305         should revamp and add a separate option.
1306
1307 Tue Jan 21 13:26:10 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1308
1309         * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
1310         partition numbering.
1311         (pk_disklabel_create_instance): Partition 1..4 are valid - not
1312         1..3.
1313         (is_iso9660): New function, verify a CD9660 File system.
1314         (pk_disklabel_create_instance): Start expanding so that active
1315         partition selection is supported.
1316
1317 Mon Jan 20 11:20:15 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1318
1319         * The cap object was retaining a reference to the instance of a
1320         device after it was deleted. Instead add and remove cap's from the
1321         cap db as they are created and deleted.  This ensuring that a
1322         capibility is only used during the lifetime of the corresponding
1323         object.
1324
1325         * cap.h, cap.c: Correct cap type - was signed32 should be
1326         signed_cell.
1327
1328         * cap.c (cap_add, cap_remove): New methods for cap object that
1329         allow the explicit addition and removal of internal objects that
1330         the cap knows about.
1331
1332         * cap.c (cap_init): Rewrite.  Verify that the only objects
1333         remaining in the cap data base are those that were entered first.
1334         Thse objects will be the permenant ones.
1335         * device.c (device_init_address): Remember to initialize the cap
1336         database.
1337
1338         * device.c (device_create_instance_from): Explicitly add device
1339         instances to the cap database.  Simplify create code.
1340         (device_instance_delete): Explicitly remove device instances from
1341         the cap database.
1342
1343         * device.c (device_create_from): Explicitly add a device to the
1344         cap data base.
1345
1346         * device.c (device_create_from): Always set the cap members.

1356 Sun Jan 19 15:28:23 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1357
1358         * The memory "claim" and "release" methods take an address and
1359         size as arguments.  These may be multi cell values. Initially fix
1360         the memory code so that they check/detect this.  Leave the
1361         adjustment of any clients to later.
1362
1363         * hw_memory.c (hw_memory_instance_claim,
1364         hw_memory_instance_release): Handle multi-cell memory devices.
1365
1366         * hw_memory.c (hw_memory_instance_claim): Be tolerant towards the

1370
1371         * device.h, device.c (device_instance_call_method): Correct return
1372         type - can return either 0 or -1, hence should be a signed type.

1381
1382         * emul_chirp.c (chirp_emul_claim): Implement using the "claim"
1383         method belonging to "/chosen/memory".
1384         (chirm_emul_release): Ditto.
1385
1386         * Makefile.in (LIB_INLINE_SRC): Remove emul_* from list of files
1387         that are inlined.  These modules are called via a table and are
1388         not made inline.
1389
1390         * hw_init.c (update_for_binary_section): Fix failure to allocate
1391         memory used by the binary in real-mode executions. If "claim"
1392         property is present, allocate memory from the "/chosen/memory"
1393         device.
1394
1395         * emul_chirp.c (emul_chirp_create): Specify that memory should be
1396         claimed when loading a real image.
1397
1398         * hw_memory.c (hw_memory_instance_claim): Don't page align memory
1399         allocations.
1400

2583
2584         * std-config.h (SEMANTICS_INLINE): By default, mask out the
2585         inlining of semantic functions from DEFAULT_INLINE.  Almost all

2588
2589         * std-config.h (ICACHE_INLINE): Ditto.
2590

2618
2619         * gen-idecode.c (print_idecode_switch_illegal): Include a break
2620         when generating illegal instructions.  This was commented out
2621         which is a hangover from looking a at switch statements generated
2622         using indirect jumps.
2623
2624 Tue Jul 23 20:57:01 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2625

2631
2632         * gen-support.c (gen_support_h): Add optional include to created
2633         support.h so that, like cpu, it is optionally inlined for all

2636         same as cpu.[hc].
2637
2638         * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2639         name for a lable and then branch to it.
2640

2644
2645 Wed Jul 24 14:02:42 1996  Andrew Cagney  <cagney@sawnoff.highland.com.au>
2646

2656         * configure: rebuild.
2657
2658 Mon Jul 22 23:25:08 1996  Andrew Cagney  <cagney@highland.com.au>
2659
2660         * configure.in (--enable-sim-hardware, --enable-sim-packages): New
2661         configuration options.  Let the user specify the packages or
2662         hardware devices that are to be included in the build.  Makes it
2663         possible for user packages to be specified.
2664
2665         * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
2666         hardware instead of checking it using ls.  configure.in should
2667         have taken care of any problems.
2668         (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
2669
2670 Mon Jul 22 22:38:59 1996  Andrew Cagney  <cagney@highland.com.au>
2671
2672         * psim.c (psim_options): Enter the argument to the memory size
2673         option directly into the device tree.  Was using atol() which is
2674         dangerously non portable.
2675
2676 Mon Jul 22 22:17:08 1996  Andrew Cagney  <cagney@highland.com.au>
2677
2678         * configure.in (icache): Extend icache flag to include an insn

2696
2697         * emul_generic.c (emul_add_tree_options): Was incorrectly setting
2698         the strict-alignment option when hardwired for non-strict
2699         alignment.

2704
2705         * ppc-instructions: Adjust so that references are to MY_INDEX and
2706         not my_index.
2707
2708 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2709
2710         * gen-idecode.c: Output the complete run_until_stop function
2711         instead of just the code to handle a single instruction issue.
2712         * : Have the generated idecode.c include inline.c (instead of psim.c).
2713
2714         * std-config.h: Change psim.c so that it isn't inlined (as this is
2715         no longer needed).
2716
2717         * psim.c (run_until_stop): Delete the old run_until_stop function
2718         instead calling the idecode_run and idecode_run_until_stop
2719         functions that gen-idecode.c is now creating.
2720
2721 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2722
2723         * dgen.c: Maintenance - update to use new features found in lf.c.

2729
2730         * debug.c (TRACE, ITRACE, DTRACE): Have GCC instead of CPP
2731         eliminate trace statements.
2732
2733         * debug.c: Change trace format so that it is consistent

2746         corresponding call to ITRACE so that it still matches.
2747
2748         * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
2749         of ITRACE.  The CPP line directives would have previously set the
2750         line-nr and file name so ITRACE isn't needed.
2751
2752 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2753
2754         * gen-idecode.c (print_jump_until_stop_body): New function and
2755         idecode generation option.  Instead of generating and calling
2756         separate functions containing the semantic and icache code
2757         generate a single monolythic function and use goto's (and GCC's
2758         indirect jump) to move between code blocks.

2761
2762         * configure.in: New option --enable-sim-jump (default disabled)
2763
2764         * ppc-instructions: Eliminate any uses of labels and goto's.

2766         is being create.
2767
2768         * ppc-opcode-jump: New file.  Set of opcode rules useful when
2769         testing jumping idecodes.

2772
2773         * gen-idecode.c: Optionally include the semantic code for an
2774         instruction in the function that is doing the decoding.
2775
2776         * igen.c: Add option (-C) to generate semantics in the instruction
2777         decode functions.
2778
2779         * configure.in (--enable-sim-icache): Accept an option list such
2780         as 1024,define.  Add a new choice to the list - semantic - which
2781         will cause igen to generate instruction decode functions that
2782         include the corresponding semantic code.
2783
2784 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2785

2787         Enable/disable the inclusion of CPP line directives in the
2788         generated files.  Such directives refer back to the source files
2789         used when generating the simulator code.
2790
2791         * Makefile.in (sim_line_nr): Pass to igen.
2792

3470         checks for the posibility that a recent change to the MSR may have
3471         made it possible to deliver an interrupt that was previously
