420 Make the simulator compatible with the MPC750. It would be nicer
421 to make this a real multi-sim, but that's more work than we have
422 time for.
423 * emul_generic.c (emul_add_tree_options): Only require strict
424 alignment if it was explicitly requested at configuration time.
425 Don't make it the default for little-endian machines.
426 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
427 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
428 THRM2, THRM3): Plop in the MPC750 SPR registers.
429 (DABR): This is weird. This was HID5, but the PPC spec says this
430 should be DABR; why did some random processor use it for something
431 else? The HID5 entry dates back to the original checkin of the
432 simulator code in 1995, so remove it.
433 * sim_calls.c (register_names): Delete this; since the user can
434 now change GDB's list of register names dynamically, we can't
435 pretend there's a static mapping here.
436 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
437 function to get the register name. That ought to be accurate.
438 However, we're changing a compile-time dependency (using the
439 REGISTER_NAMES macro) into a link- and run-time dependency
440 (calling REGISTER_NAME, which happens to be a function call on the
441 PPC).
442
4431999-01-22 Jim Lemke <jlemke@cygnus.com>
444
445 * igen.c(gen_semantics_[ch]): setup/use of new option
446 (-o mpc860c0[=n]).

449 psim.c(is_num - added, psim_options): Parse and init new option.
450 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
451
4521998-12-01 Ken Raeburn <raeburn@cygnus.com>
453
454 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

472
473Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
474
475 * table.c (table_open): For cygwin hosts, we need to use the
476 return value from the read routine as the number of bytes to
477 process. This apparently is due to text-mode vs binary-mode. If
478 the mounts are done text-mode, then the size returnedby fstat()
479 may be different than the number of bytes "read" in text mode.
480
481Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>

505
506 * Makefile.in: The run target depended on a target psim$(EXEEXT),
507 but there was no such target, only plain psim. So I changed the
508 run target to depend on psim.

874 entry code so that it involves a mask + test instead of shift +
875 shift + mask + test.
876
877 * gen-idecode.c: Correct generated igen body so that it no drops
878 or doubles clock interrupts.

888
889Wed Jan 29 12:32:41 1997 Michael Meissner <meissner@tiktok.cygnus.com>
890
891 * configure.in (sim_callback): If the gdb is post 4.16, configure
892 callback support from the common directory.
893 * configure: Regenerate.
894
895 * Makefile.in (BUILT_SRC_WO_CONFIG): Add targ-vals.{h,def} and
896 targ-map.c.

902 (clean): Remove gentmap.
903
904Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
905
906 * igen wasn't aborting if the opcode table contained no valid
907 fields.
908
909 * misc.c (name2i): Possibly abort if an invalid name is
910 encountered.
911 * ld-decode.c: Abort if the table type isn't found.
912
913Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
914
915 * When performance monitoring is disabled, it is still possible to
916 determine the simulation speed by looking at the number of elapsed
917 ticks recorded by the event queue.
918
919 * psim.c (psim_write_register, psim_read_register): Force the cpu
920 to zero when it is either of `-1' or `nr_cpus'. In both cases the
921 next cpu would be zero any way.
922
923 * mon.c (mon_print_info): If possible, print the system cycle
924 performance. This is an indication of the number of instructions
925 per second.
926
927Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
928
929 * The code to allow an event queue to be updated during a signal
930 was missing. For main.c, a cntrl-c simulation termination wasn't
931 handled cleanly.
932
933 * The simulation would not correctly restart if an event requested
934 that the simulation be halted.
935
936 * psim.c (psim_options): Add hack to -i option to optionally
937 include a level vis -i2.
938 (psim_usage): Document.
939
940 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
941 cntrl-c occures schedule an event to halt the simulation.
942 (main): Catch CNTRL-C signals with the function cntrl_c.
943
944 * events.c (event_queue_process): Mask interrupts while

947 (event_queue_schedule_after_signal): Ditto.
948
949 * events.c (event_queue_process): Mark the event queue as being in
950 the processing state when processing has started. Adjust code
951 so that it is tolerant of halts.
952 (event_queue_init): Start the event queue out with processing
953 false.
954 (event_queue_tick): Check that processing isn't still being
955 performed.
956
957 * gen-idecode.c (print_run_until_stop_body): Call
958 event_queue_process_events to clear possibly pending events before
959 starting a simulation run. Re-arange main loop so that simulator
960 is correctly restarted when an event halts the simulation.
961
962 * psim.c (psim_halt): Handle an event halting the simulation.
963 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
964 reworked idecode.
965
966Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
967
968 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
969 RA. Based on instruction frequency stats, expand additional
970 instructions.
971 * ppc-instructions: Change all `RA == 0' to RA_is_0.
972
973 * ppc-opcode-stupid: Move all but the basic table in -complex into
974 here. Update to new format.
975
976 * Makefile.in (tmp-defines): New target. Force defines.h to always
977 be built. Hence get ppc-opcode-goto to build.
978
979Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
980
981 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
982 Implement.
983
984Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
985
986 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
987 to be initialized independant of the rest of the simulation
988 initalization. Otherwize a trace option explictly set from gdb
989 could be overridden by hw_trace.
990
991 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
992
993 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
994 debug.c. It could be much simpler.
995
996Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
997
998 * Some devices support removable media. Add hooks to the disk
999 device so that it supports this.
1000

1010 image property list.
1011 (hw_disk_init_address): Change the file property so that it is a
1012 string array - use the first entry for the initial file image.
1013
1014 * tree.c (print_string_aray_property): New function - print a
1015 string array.
1016 (print_properties): Adjust.
1017 (print_string): Write a string, handling double quotes.
1018

1023
1024 * psim.c (psim_command): New function, parse more complex psim
1025 commands such as "change-media" and "trace".

1027
1028Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1029
1030 * For expressions like (RA == 0) that are entered in to the cache
1031 as RA_is_0. If possible generate the result of the expression so
1032 that the compiler gets a better chance of eliminating dead
1033 branches.
1034
1035 * gen-icache.c (print_icache_extraction): For a cache entry of
1036 the form <name>_is_<const> where it is a boolean field, generate
1037 the result of the expression instead of the expression its self.
1038 (print_icache_body): Remove code that was looking for *_is_0 and
1039 then generating corresponding definitions.
1040
1041 * gen-icache.c (print_icache_struct): If there is no cache, do not
1042 output expressions in idecode.h file.
1043
1044 * gen-icache.c (print_icache_body): Output them here.
1045
1046 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1047 expansion.
1048
1049 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
1050
1051Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1052
1053 * The code that put values in and extracted values from the cache
1054 was too compilicated. The cache table did not allow values to be
1055 computed from cache entries. #defines could only be used when a
1056 cache was present, remove the restriction.
1057
1058 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1059 scratch variable is defined when a cache entry is beinf
1060 filled. Change the definition of a COMPUTE variable to be defined
1061 when the cache entry is being used.
1062 * gen-icache.c: Update.
1063
1064 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1065 is more obvious. old_name->field_name, new_name->derived_name.
1066 * gen-icache.c: Update
1067
1068 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1069 different types of cache code - put into cache, extract from
1070 cache, no cache - an explicit argument to print_icache_body.
1071 * gen-icache.c (print_icache_extraction): Ditto.
1072
1073 * gen-semantics.c (print_c_semantic): Update use.
1074 * gen-idecode.c (print_jump_insn): Update use.
1075 * gen-icache.c (print_icache_function): Update use.
1076
1077 * igen.c (main): Change 'R' option so that it does not force the
1078 cache.
1079
1080 * configure.in (enable-sim-icache): Clarify description. Make
1081 #define one of the defaults regardless of the cache. Probably
1082 should revamp and add a separate option.
1083
1084Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1094Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1095
1096 * The cap object was retaining a reference to the instance of a
1097 device after it was deleted. Instead add and remove cap's from the
1098 cap db as they are created and deleted. This ensuring that a
1099 capibility is only used during the lifetime of the corresponding
1100 object.
1101
1102 * cap.h, cap.c: Correct cap type - was signed32 should be
1103 signed_cell.
1104
1105 * cap.c (cap_add, cap_remove): New methods for cap object that
1106 allow the explicit addition and removal of internal objects that
1107 the cap knows about.
1108
1109 * cap.c (cap_init): Rewrite. Verify that the only objects
1110 remaining in the cap data base are those that were entered first.
1111 Thse objects will be the permenant ones.

1134
1135 * The memory "claim" and "release" methods take an address and
1136 size as arguments. These may be multi cell values. Initially fix
1137 the memory code so that they check/detect this. Leave the
1138 adjustment of any clients to later.

2412 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2413 same as cpu.[hc].
2414
2415 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2416 name for a lable and then branch to it.
2417
2418 * ppc-instructions (convert_to_integer, Floating Round to
2419 Single-Precision, Floating Convert from Integer Doubleword): Use
2420 LABEL and GOTO instead of the recently added switch statements.

2446
2447Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>

2491 * std-config.h: Change psim.c so that it isn't inlined (as this is
2492 no longer needed).
2493
2494 * psim.c (run_until_stop): Delete the old run_until_stop function
2495 instead calling the idecode_run and idecode_run_until_stop
2496 functions that gen-idecode.c is now creating.

2562
2563 * configure.in: New option --enable-sim-line-nr (default enabled).
