453
454 * sim-endian.h: Don't have parameters on macro definitions which

504 the frequency at which the poll_quit callback is called.
505 (poll_quit_count): New global.
506 (sim_io_poll_quit): Only call the poll_quit callback
507 after the specified POLL_QUIT_INTERVAL.

521 Make the simulator compatible with the MPC750. It would be nicer
522 to make this a real multi-sim, but that's more work than we have
523 time for.
524 * emul_generic.c (emul_add_tree_options): Only require strict
525 alignment if it was explicitly requested at configuration time.
526 Don't make it the default for little-endian machines.
527 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
528 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
529 THRM2, THRM3): Plop in the MPC750 SPR registers.
530 (DABR): This is weird. This was HID5, but the PPC spec says this
531 should be DABR; why did some random processor use it for something
532 else? The HID5 entry dates back to the original checkin of the
533 simulator code in 1995, so remove it.
534 * sim_calls.c (register_names): Delete this; since the user can
535 now change GDB's list of register names dynamically, we can't
536 pretend there's a static mapping here.
537 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
538 function to get the register name. That ought to be accurate.
539 However, we're changing a compile-time dependency (using the
540 REGISTER_NAMES macro) into a link- and run-time dependency
541 (calling REGISTER_NAME, which happens to be a function call on the
542 PPC).
543
5441999-01-22 Jim Lemke <jlemke@cygnus.com>
545
546 * igen.c(gen_semantics_[ch]): setup/use of new option

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

572 Infinities.
573
574Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
575
576 * table.c (table_open): For cygwin hosts, we need to use the
577 return value from the read routine as the number of bytes to
578 process. This apparently is due to text-mode vs binary-mode. If
579 the mounts are done text-mode, then the size returnedby fstat()
580 may be different than the number of bytes "read" in text mode.
581
582Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>

607 * Makefile.in: The run target depended on a target psim$(EXEEXT),
608 but there was no such target, only plain psim. So I changed the
609 run target to depend on psim.
610
611Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
612
613 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
614 now defined in ../common/aclocal.m4, and the double definition causes

915 don't assume void.
916 * sim_calls.c (sim_{ctrl_c,resume}): Ditto.
917
918 * Makefile.in (callback.o): Define HAVE_CONFIG_H, so callback.c
919 includes our config.h.
920
921Tue Feb 4 13:42:59 1997 Doug Evans <dje@canuck.cygnus.com>
922
923 * configure.in: Fix typo in test for callback.c.

945
946 * gen-icache.c (print_icache_extraction): Add a reason parameter.
947 Augment each extracted field with a comment citing the codes
948 origin. Should simplify tracking down incorrect cache
949 extractions.
950

954 works for normal and boolean table entries.
955
956 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
957 valid. Handle this just like *_{read,write}_register now handles

971 max iterations exceeded.
972
973 * gen-idecode.c: Re-work the table lookup code so that it assumes
974 that the entry is a leaf by default. Simplify the boolean table
975 entry code so that it involves a mask + test instead of shift +
976 shift + mask + test.
977
978 * gen-idecode.c: Correct generated igen body so that it no drops
979 or doubles clock interrupts.
980
981

1018 ticks recorded by the event queue.
1019
1020 * psim.c (psim_write_register, psim_read_register): Force the cpu
1021 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1022 next cpu would be zero any way.

1024 * mon.c (mon_print_info): If possible, print the system cycle
1025 performance. This is an indication of the number of instructions
1026 per second.
1027
1028Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1029
1030 * The code to allow an event queue to be updated during a signal
1031 was missing. For main.c, a cntrl-c simulation termination wasn't
1032 handled cleanly.
1033
1034 * The simulation would not correctly restart if an event requested
1035 that the simulation be halted.
1036
1037 * psim.c (psim_options): Add hack to -i option to optionally
1038 include a level vis -i2.
1039 (psim_usage): Document.
1040
1041 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
1042 cntrl-c occures schedule an event to halt the simulation.

1044
1045 * events.c (event_queue_process): Mask interrupts while

1051 the processing state when processing has started. Adjust code
1052 so that it is tolerant of halts.
1053 (event_queue_init): Start the event queue out with processing
1054 false.
1055 (event_queue_tick): Check that processing isn't still being
1056 performed.
1057
1058 * gen-idecode.c (print_run_until_stop_body): Call
1059 event_queue_process_events to clear possibly pending events before
1060 starting a simulation run. Re-arange main loop so that simulator
1061 is correctly restarted when an event halts the simulation.

1063 * psim.c (psim_halt): Handle an event halting the simulation.
1064 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1065 reworked idecode.
1066
1067Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1068
1069 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1070 RA. Based on instruction frequency stats, expand additional
1071 instructions.
1072 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1073
1074 * ppc-opcode-stupid: Move all but the basic table in -complex into
1075 here. Update to new format.
1076
1077 * Makefile.in (tmp-defines): New target. Force defines.h to always
1078 be built. Hence get ppc-opcode-goto to build.
1079
1080Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1081
1082 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1083 Implement.
1084
1085Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1086
1087 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1088 to be initialized independant of the rest of the simulation
1089 initalization. Otherwize a trace option explictly set from gdb
1090 could be overridden by hw_trace.
1091
1092 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1093
1094 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1095 debug.c. It could be much simpler.
1096
1097Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1098
1099 * Some devices support removable media. Add hooks to the disk
1100 device so that it supports this.

1110 media. If no file image is specified, use the next one in the
1111 image property list.
1112 (hw_disk_init_address): Change the file property so that it is a
1113 string array - use the first entry for the initial file image.
1114
1115 * tree.c (print_string_aray_property): New function - print a
1116 string array.
1117 (print_properties): Adjust.
1118 (print_string): Write a string, handling double quotes.

1128
1129Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1130
1131 * For expressions like (RA == 0) that are entered in to the cache
1132 as RA_is_0. If possible generate the result of the expression so
1133 that the compiler gets a better chance of eliminating dead
1134 branches.
1135
1136 * gen-icache.c (print_icache_extraction): For a cache entry of
1137 the form <name>_is_<const> where it is a boolean field, generate
1138 the result of the expression instead of the expression its self.
1139 (print_icache_body): Remove code that was looking for *_is_0 and
1140 then generating corresponding definitions.
1141
1142 * gen-icache.c (print_icache_struct): If there is no cache, do not
1143 output expressions in idecode.h file.
1144
1145 * gen-icache.c (print_icache_body): Output them here.
1146
1147 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1148 expansion.
1149

1151
1152Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1153
1154 * The code that put values in and extracted values from the cache
1155 was too compilicated. The cache table did not allow values to be
1156 computed from cache entries. #defines could only be used when a
1157 cache was present, remove the restriction.
1158
1159 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1160 scratch variable is defined when a cache entry is beinf
1161 filled. Change the definition of a COMPUTE variable to be defined
1162 when the cache entry is being used.
1163 * gen-icache.c: Update.
1164
1165 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1166 is more obvious. old_name->field_name, new_name->derived_name.
1167 * gen-icache.c: Update
1168
1169 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1170 different types of cache code - put into cache, extract from
1171 cache, no cache - an explicit argument to print_icache_body.
1172 * gen-icache.c (print_icache_extraction): Ditto.
1173
1174 * gen-semantics.c (print_c_semantic): Update use.
1175 * gen-idecode.c (print_jump_insn): Update use.
1176 * gen-icache.c (print_icache_function): Update use.
1177
1178 * igen.c (main): Change 'R' option so that it does not force the
1179 cache.
1180
1181 * configure.in (enable-sim-icache): Clarify description. Make
1182 #define one of the defaults regardless of the cache. Probably
1183 should revamp and add a separate option.
1184
1185Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1186

1195Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1196
1197 * The cap object was retaining a reference to the instance of a
1198 device after it was deleted. Instead add and remove cap's from the
1199 cap db as they are created and deleted. This ensuring that a
1200 capibility is only used during the lifetime of the corresponding
1201 object.
1202
1203 * cap.h, cap.c: Correct cap type - was signed32 should be
1204 signed_cell.
1205
1206 * cap.c (cap_add, cap_remove): New methods for cap object that
1207 allow the explicit addition and removal of internal objects that
1208 the cap knows about.
1209
1210 * cap.c (cap_init): Rewrite. Verify that the only objects
1211 remaining in the cap data base are those that were entered first.
1212 Thse objects will be the permenant ones.
1213 * device.c (device_init_address): Remember to initialize the cap
1214 database.
1215
1216 * device.c (device_create_instance_from): Explicitly add device

1235
1236 * The memory "claim" and "release" methods take an address and
1237 size as arguments. These may be multi cell values. Initially fix
1238 the memory code so that they check/detect this. Leave the
1239 adjustment of any clients to later.
1240
1241 * hw_memory.c (hw_memory_instance_claim,
1242 hw_memory_instance_release): Handle multi-cell memory devices.

1248
1249 * device.h, device.c (device_instance_call_method): Correct return
1250 type - can return either 0 or -1, hence should be a signed type.

1252
1253 * hw_memory.c (hw_memory_instance_claim,
1254 hw_memory_instance_release): Update.

1266 not made inline.
1267
1268 * hw_init.c (update_for_binary_section): Fix failure to allocate
1269 memory used by the binary in real-mode executions. If "claim"
1270 property is present, allocate memory from the "/chosen/memory"
1271 device.
1272
1273 * emul_chirp.c (emul_chirp_create): Specify that memory should be
1274 claimed when loading a real image.

2513 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2514 same as cpu.[hc].
2515
2516 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2517 name for a lable and then branch to it.
2518
2519 * ppc-instructions (convert_to_integer, Floating Round to
2520 Single-Precision, Floating Convert from Integer Doubleword): Use
2521 LABEL and GOTO instead of the recently added switch statements.

2592 * std-config.h: Change psim.c so that it isn't inlined (as this is
2593 no longer needed).
2594
2595 * psim.c (run_until_stop): Delete the old run_until_stop function
2596 instead calling the idecode_run and idecode_run_until_stop
2597 functions that gen-idecode.c is now creating.

2647 testing jumping idecodes.
2648

3602
3603 * corefile-n.h (core_map_read_N): When mapping from an address to
3604 a device, do not subtract the devices base. The device its self
3605 can do this. Brings the behavour into line with OpenBoot.

3617 did not allow interrupts to be wired up as a general net (edges).
3618 Re-implement so that interrupt events can be passed to multiple
3619 controllers and interrupt controllers can further propogate
3620 interrupt events.
3621
3622 * device.c (attach_device_interrupt_edge) : New, Ditto

3645 standard mapping between a devices internal representation (a
3646 pointer) and its external (or what is passed to a client)
3647 representation (a phandle). Implement using the cap object
3648 attached to the root node.
3649
3650 * device.c (device_to_external) : Ditto
3651 * device.c (external_to_device_instance) : Ditto but for ihandle

3670
3671 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3672 read/write calls for buffer transfers. This will cause a fault to
3673 occure if the transfer fails. CHRP catches the fault while the
3674 others suffer the consequences.
