425 Make the simulator compatible with the MPC750. It would be nicer
426 to make this a real multi-sim, but that's more work than we have
427 time for.
428 * emul_generic.c (emul_add_tree_options): Only require strict
429 alignment if it was explicitly requested at configuration time.
430 Don't make it the default for little-endian machines.
431 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
432 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
433 THRM2, THRM3): Plop in the MPC750 SPR registers.
434 (DABR): This is weird. This was HID5, but the PPC spec says this
435 should be DABR; why did some random processor use it for something
436 else? The HID5 entry dates back to the original checkin of the
437 simulator code in 1995, so remove it.
438 * sim_calls.c (register_names): Delete this; since the user can
439 now change GDB's list of register names dynamically, we can't
440 pretend there's a static mapping here.
441 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
442 function to get the register name. That ought to be accurate.
443 However, we're changing a compile-time dependency (using the
444 REGISTER_NAMES macro) into a link- and run-time dependency
445 (calling REGISTER_NAME, which happens to be a function call on the
446 PPC).
447
4481999-01-22 Jim Lemke <jlemke@cygnus.com>
449
450 * igen.c(gen_semantics_[ch]): setup/use of new option
451 (-o mpc860c0[=n]).

454 psim.c(is_num - added, psim_options): Parse and init new option.
455 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
456

477
478Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
479
480 * table.c (table_open): For cygwin hosts, we need to use the
481 return value from the read routine as the number of bytes to
482 process. This apparently is due to text-mode vs binary-mode. If
483 the mounts are done text-mode, then the size returnedby fstat()
484 may be different than the number of bytes "read" in text mode.
485
486Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>

878 that the entry is a leaf by default. Simplify the boolean table
879 entry code so that it involves a mask + test instead of shift +
880 shift + mask + test.
881
882 * gen-idecode.c: Correct generated igen body so that it no drops
883 or doubles clock interrupts.
884

891 * configure.in (sim_callback, sim_targ_vals): Set sim_targ_valls
892 if common callback is present.
893
894Wed Jan 29 12:32:41 1997 Michael Meissner <meissner@tiktok.cygnus.com>
895
896 * configure.in (sim_callback): If the gdb is post 4.16, configure
897 callback support from the common directory.
898 * configure: Regenerate.
899
900 * Makefile.in (BUILT_SRC_WO_CONFIG): Add targ-vals.{h,def} and
901 targ-map.c.

907 (clean): Remove gentmap.
908
909Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
910
911 * igen wasn't aborting if the opcode table contained no valid
912 fields.
913
914 * misc.c (name2i): Possibly abort if an invalid name is
915 encountered.
916 * ld-decode.c: Abort if the table type isn't found.
917
918Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
919
920 * When performance monitoring is disabled, it is still possible to
921 determine the simulation speed by looking at the number of elapsed
922 ticks recorded by the event queue.
923
924 * psim.c (psim_write_register, psim_read_register): Force the cpu
925 to zero when it is either of `-1' or `nr_cpus'. In both cases the
926 next cpu would be zero any way.
927
928 * mon.c (mon_print_info): If possible, print the system cycle
929 performance. This is an indication of the number of instructions
930 per second.
931
932Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
933
934 * The code to allow an event queue to be updated during a signal
935 was missing. For main.c, a cntrl-c simulation termination wasn't
936 handled cleanly.
937
938 * The simulation would not correctly restart if an event requested
939 that the simulation be halted.
940
941 * psim.c (psim_options): Add hack to -i option to optionally
942 include a level vis -i2.
943 (psim_usage): Document.
944
945 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
946 cntrl-c occures schedule an event to halt the simulation.
947 (main): Catch CNTRL-C signals with the function cntrl_c.
948
949 * events.c (event_queue_process): Mask interrupts while
950 manipulating the async event queue.

954 * events.c (event_queue_process): Mark the event queue as being in
955 the processing state when processing has started. Adjust code
956 so that it is tolerant of halts.
957 (event_queue_init): Start the event queue out with processing
958 false.
959 (event_queue_tick): Check that processing isn't still being
960 performed.
961
962 * gen-idecode.c (print_run_until_stop_body): Call
963 event_queue_process_events to clear possibly pending events before
964 starting a simulation run. Re-arange main loop so that simulator
965 is correctly restarted when an event halts the simulation.
966
967 * psim.c (psim_halt): Handle an event halting the simulation.
968 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
969 reworked idecode.
970
971Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
972
973 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
974 RA. Based on instruction frequency stats, expand additional
975 instructions.
976 * ppc-instructions: Change all `RA == 0' to RA_is_0.
977
978 * ppc-opcode-stupid: Move all but the basic table in -complex into
979 here. Update to new format.
980
981 * Makefile.in (tmp-defines): New target. Force defines.h to always
982 be built. Hence get ppc-opcode-goto to build.
983
984Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
985
986 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
987 Implement.
988
989Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
990
991 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
992 to be initialized independant of the rest of the simulation
993 initalization. Otherwize a trace option explictly set from gdb
994 could be overridden by hw_trace.
995
996 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
997
998 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
999 debug.c. It could be much simpler.
1000
1001Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1002
1003 * Some devices support removable media. Add hooks to the disk
1004 device so that it supports this.
1005
1006 * device.c (device_add_string_array_property,

1015 image property list.
1016 (hw_disk_init_address): Change the file property so that it is a
1017 string array - use the first entry for the initial file image.
1018
1019 * tree.c (print_string_aray_property): New function - print a
1020 string array.
1021 (print_properties): Adjust.
1022 (print_string): Write a string, handling double quotes.

1032
1033Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1034
1035 * For expressions like (RA == 0) that are entered in to the cache
1036 as RA_is_0. If possible generate the result of the expression so
1037 that the compiler gets a better chance of eliminating dead
1038 branches.
1039
1040 * gen-icache.c (print_icache_extraction): For a cache entry of
1041 the form <name>_is_<const> where it is a boolean field, generate
1042 the result of the expression instead of the expression its self.
1043 (print_icache_body): Remove code that was looking for *_is_0 and
1044 then generating corresponding definitions.
1045
1046 * gen-icache.c (print_icache_struct): If there is no cache, do not
1047 output expressions in idecode.h file.
1048
1049 * gen-icache.c (print_icache_body): Output them here.
1050
1051 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1052 expansion.
1053
1054 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
1055
1056Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1057
1058 * The code that put values in and extracted values from the cache
1059 was too compilicated. The cache table did not allow values to be
1060 computed from cache entries. #defines could only be used when a
1061 cache was present, remove the restriction.
1062
1063 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1064 scratch variable is defined when a cache entry is beinf
1065 filled. Change the definition of a COMPUTE variable to be defined
1066 when the cache entry is being used.
1067 * gen-icache.c: Update.
1068
1069 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1072
1073 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1074 different types of cache code - put into cache, extract from
1075 cache, no cache - an explicit argument to print_icache_body.
1076 * gen-icache.c (print_icache_extraction): Ditto.
1077
1078 * gen-semantics.c (print_c_semantic): Update use.
1079 * gen-idecode.c (print_jump_insn): Update use.
1080 * gen-icache.c (print_icache_function): Update use.
1081
1082 * igen.c (main): Change 'R' option so that it does not force the
1083 cache.
1084
1085 * configure.in (enable-sim-icache): Clarify description. Make
1086 #define one of the defaults regardless of the cache. Probably
1087 should revamp and add a separate option.
1088
1089Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1099Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1100
1101 * The cap object was retaining a reference to the instance of a
1102 device after it was deleted. Instead add and remove cap's from the
1103 cap db as they are created and deleted. This ensuring that a
1104 capibility is only used during the lifetime of the corresponding
1105 object.
1106
1107 * cap.h, cap.c: Correct cap type - was signed32 should be
1108 signed_cell.
1109
1110 * cap.c (cap_add, cap_remove): New methods for cap object that
1111 allow the explicit addition and removal of internal objects that
1112 the cap knows about.
1113
1114 * cap.c (cap_init): Rewrite. Verify that the only objects
1115 remaining in the cap data base are those that were entered first.
1116 Thse objects will be the permenant ones.

1140 * The memory "claim" and "release" methods take an address and
1141 size as arguments. These may be multi cell values. Initially fix
1142 the memory code so that they check/detect this. Leave the
1143 adjustment of any clients to later.
1144

2418 same as cpu.[hc].
2419
2420 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2421 name for a lable and then branch to it.
2422

2451
2452Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>

2496 * std-config.h: Change psim.c so that it isn't inlined (as this is
2497 no longer needed).
2498
2499 * psim.c (run_until_stop): Delete the old run_until_stop function
2500 instead calling the idecode_run and idecode_run_until_stop
2501 functions that gen-idecode.c is now creating.

2567
2568 * configure.in: New option --enable-sim-line-nr (default enabled).
