433 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
434
435 * configure: Regenerated to track ../common/aclocal.m4 changes.
436
437 1999-05-08 Felix Lee <flee@cygnus.com>
438
439 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
440 * configure: Regenerated to track ../common/aclocal.m4 changes.
441
442 1999-04-02 Keith Seitz <keiths@cygnus.com>
443
444 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
445 the frequency at which the poll_quit callback is called.
446 (poll_quit_count): New global.
447 (sim_io_poll_quit): Only call the poll_quit callback
448 after the specified POLL_QUIT_INTERVAL.
449
450 1999-02-22 Jim Lemke <jlemke@cygnus.com>
451
452 * dc-complex: Force expansion on all bits of field BO.
453 Previously, the least-significant (prediction) bit was ignored.
454 * ppc-instructions (conditional branches): Implement mpc860c0 option.
455 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
456 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
457 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
458 * interrupts.c (program_interrupt): Added handling for above interrupt.
459
460 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
461
462 Make the simulator compatible with the MPC750. It would be nicer
463 to make this a real multi-sim, but that's more work than we have
464 time for.
465 * emul_generic.c (emul_add_tree_options): Only require strict
466 alignment if it was explicitly requested at configuration time.
467 Don't make it the default for little-endian machines.
468 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
469 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
470 THRM2, THRM3): Plop in the MPC750 SPR registers.
471 (DABR): This is weird. This was HID5, but the PPC spec says this
472 should be DABR; why did some random processor use it for something
473 else? The HID5 entry dates back to the original checkin of the
474 simulator code in 1995, so remove it.
475 * sim_calls.c (register_names): Delete this; since the user can
476 now change GDB's list of register names dynamically, we can't
477 pretend there's a static mapping here.
478 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
479 function to get the register name. That ought to be accurate.
480 However, we're changing a compile-time dependency (using the
481 REGISTER_NAMES macro) into a link- and run-time dependency
482 (calling REGISTER_NAME, which happens to be a function call on the
483 PPC).
484
485 1999-01-22 Jim Lemke <jlemke@cygnus.com>
486
487 * igen.c(gen_semantics_[ch]): setup/use of new option
488 (-o mpc860c0[=n]).

491 psim.c(is_num - added, psim_options): Parse and init new option.
492 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
493

495
496 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

506 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
507 poll the external environment.
508

510
511 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
512 fractional type, so that quiet NaN's aren't treated like
513 Infinities.
514
515 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
516
517 * table.c (table_open): For cygwin hosts, we need to use the
518 return value from the read routine as the number of bytes to
519 process. This apparently is due to text-mode vs binary-mode. If
520 the mounts are done text-mode, then the size returnedby fstat()
521 may be different than the number of bytes "read" in text mode.
522
523 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
524
525 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

542 * configure: Regenerate.
543 * emul_{netbsd,unix}.c (toplevel): No longer try to include

545
546 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
547
548 * Makefile.in: The run target depended on a target psim$(EXEEXT),
549 but there was no such target, only plain psim. So I changed the
550 run target to depend on psim.
551
552 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
553
554 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
555 now defined in ../common/aclocal.m4, and the double definition causes
556 problems with AC_SUBST of EXEEXT.

885 Wed Feb 5 10:56:27 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
886
887 * gen-icache.c (print_icache_extraction): Add a reason parameter.

911 (psim_max_iterations_exceeded): New function, abort simulation if
912 max iterations exceeded.
913
914 * gen-idecode.c: Re-work the table lookup code so that it assumes
915 that the entry is a leaf by default. Simplify the boolean table
916 entry code so that it involves a mask + test instead of shift +
917 shift + mask + test.
918
919 * gen-idecode.c: Correct generated igen body so that it no drops
920 or doubles clock interrupts.
921
922
923 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

945
946 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
947
948 * igen wasn't aborting if the opcode table contained no valid
949 fields.
950
951 * misc.c (name2i): Possibly abort if an invalid name is
952 encountered.
953 * ld-decode.c: Abort if the table type isn't found.
954
955 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
956
957 * When performance monitoring is disabled, it is still possible to
958 determine the simulation speed by looking at the number of elapsed
959 ticks recorded by the event queue.
960
961 * psim.c (psim_write_register, psim_read_register): Force the cpu
962 to zero when it is either of `-1' or `nr_cpus'. In both cases the
963 next cpu would be zero any way.
964
965 * mon.c (mon_print_info): If possible, print the system cycle
966 performance. This is an indication of the number of instructions
967 per second.
968
969 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
970
971 * The code to allow an event queue to be updated during a signal
972 was missing. For main.c, a cntrl-c simulation termination wasn't
973 handled cleanly.
974
975 * The simulation would not correctly restart if an event requested
976 that the simulation be halted.
977
978 * psim.c (psim_options): Add hack to -i option to optionally
979 include a level vis -i2.
980 (psim_usage): Document.
981
982 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
983 cntrl-c occures schedule an event to halt the simulation.

985
986 * events.c (event_queue_process): Mask interrupts while
987 manipulating the async event queue.

992 the processing state when processing has started. Adjust code
993 so that it is tolerant of halts.
994 (event_queue_init): Start the event queue out with processing
995 false.
996 (event_queue_tick): Check that processing isn't still being
997 performed.
998
999 * gen-idecode.c (print_run_until_stop_body): Call
1000 event_queue_process_events to clear possibly pending events before
1001 starting a simulation run. Re-arange main loop so that simulator
1002 is correctly restarted when an event halts the simulation.
1003
1004 * psim.c (psim_halt): Handle an event halting the simulation.
1005 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1006 reworked idecode.
1007
1008 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1009
1010 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1011 RA. Based on instruction frequency stats, expand additional
1012 instructions.
1013 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1014
1015 * ppc-opcode-stupid: Move all but the basic table in -complex into
1016 here. Update to new format.
1017
1018 * Makefile.in (tmp-defines): New target. Force defines.h to always
1019 be built. Hence get ppc-opcode-goto to build.
1020
1021 Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1022
1023 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1024 Implement.
1025
1026 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1027
1028 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1029 to be initialized independant of the rest of the simulation
1030 initalization. Otherwize a trace option explictly set from gdb
1031 could be overridden by hw_trace.
1032
1033 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1034
1035 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1036 debug.c. It could be much simpler.
1037
1038 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1039
1040 * Some devices support removable media. Add hooks to the disk
1041 device so that it supports this.

1052 image property list.
1053 (hw_disk_init_address): Change the file property so that it is a
1054 string array - use the first entry for the initial file image.
1055
1056 * tree.c (print_string_aray_property): New function - print a
1057 string array.
1058 (print_properties): Adjust.
1059 (print_string): Write a string, handling double quotes.

1069
1070 Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1071
1072 * For expressions like (RA == 0) that are entered in to the cache
1073 as RA_is_0. If possible generate the result of the expression so
1074 that the compiler gets a better chance of eliminating dead
1075 branches.
1076
1077 * gen-icache.c (print_icache_extraction): For a cache entry of
1078 the form <name>_is_<const> where it is a boolean field, generate
1079 the result of the expression instead of the expression its self.
1080 (print_icache_body): Remove code that was looking for *_is_0 and
1081 then generating corresponding definitions.
1082
1083 * gen-icache.c (print_icache_struct): If there is no cache, do not
1084 output expressions in idecode.h file.
1085
1086 * gen-icache.c (print_icache_body): Output them here.
1087
1088 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1089 expansion.
1090
1091 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
1092
1093 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1094
1095 * The code that put values in and extracted values from the cache
1096 was too compilicated. The cache table did not allow values to be
1097 computed from cache entries. #defines could only be used when a
1098 cache was present, remove the restriction.
1099
1100 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1101 scratch variable is defined when a cache entry is beinf
1102 filled. Change the definition of a COMPUTE variable to be defined
1103 when the cache entry is being used.
1104 * gen-icache.c: Update.
1105
1106 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1109
1110 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1111 different types of cache code - put into cache, extract from
1112 cache, no cache - an explicit argument to print_icache_body.
1113 * gen-icache.c (print_icache_extraction): Ditto.
1114
1115 * gen-semantics.c (print_c_semantic): Update use.
1116 * gen-idecode.c (print_jump_insn): Update use.
1117 * gen-icache.c (print_icache_function): Update use.
1118
1119 * igen.c (main): Change 'R' option so that it does not force the
1120 cache.
1121
1122 * configure.in (enable-sim-icache): Clarify description. Make
1123 #define one of the defaults regardless of the cache. Probably
1124 should revamp and add a separate option.
1125
1126 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1136 Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1137
1138 * The cap object was retaining a reference to the instance of a
1139 device after it was deleted. Instead add and remove cap's from the
1140 cap db as they are created and deleted. This ensuring that a
1141 capibility is only used during the lifetime of the corresponding
1142 object.
1143
1144 * cap.h, cap.c: Correct cap type - was signed32 should be
1145 signed_cell.
1146
1147 * cap.c (cap_add, cap_remove): New methods for cap object that
1148 allow the explicit addition and removal of internal objects that
1149 the cap knows about.
1150
1151 * cap.c (cap_init): Rewrite. Verify that the only objects
1152 remaining in the cap data base are those that were entered first.
1153 Thse objects will be the permenant ones.
1154 * device.c (device_init_address): Remember to initialize the cap
1155 database.
1156
1157 * device.c (device_create_instance_from): Explicitly add device

1177 * The memory "claim" and "release" methods take an address and
1178 size as arguments. These may be multi cell values. Initially fix
1179 the memory code so that they check/detect this. Leave the
1180 adjustment of any clients to later.
1181
1182 * hw_memory.c (hw_memory_instance_claim,
1183 hw_memory_instance_release): Handle multi-cell memory devices.

1189
1190 * device.h, device.c (device_instance_call_method): Correct return

2402
2403 * std-config.h (SEMANTICS_INLINE): By default, mask out the
2404 inlining of semantic functions from DEFAULT_INLINE. Almost all

2436 always update the cache_entries semantic and address fields.
2437
2438 * gen-idecode.c (print_idecode_switch_illegal): Include a break

2453 modules that include it.
2454 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2455 same as cpu.[hc].
2456
2457 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2458 name for a lable and then branch to it.
2459
2460 * ppc-instructions (convert_to_integer, Floating Round to
2461 Single-Precision, Floating Convert from Integer Doubleword): Use
2462 LABEL and GOTO instead of the recently added switch statements.

2485 hardware instead of checking it using ls. configure.in should
2486 have taken care of any problems.
2487 (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
2488
2489 Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
2490
2491 * psim.c (psim_options): Enter the argument to the memory size
2492 option directly into the device tree. Was using atol() which is

2532
2533 * std-config.h: Change psim.c so that it isn't inlined (as this is
2534 no longer needed).
2535
2536 * psim.c (run_until_stop): Delete the old run_until_stop function
2537 instead calling the idecode_run and idecode_run_until_stop
2538 functions that gen-idecode.c is now creating.

2604
2605 * configure.in: New option --enable-sim-line-nr (default enabled).

3586 standard mapping between a devices internal representation (a
3587 pointer) and its external (or what is passed to a client)
3588 representation (a phandle). Implement using the cap object
3589 attached to the root node.
3590
3591 * device.c (device_to_external) : Ditto
3592 * device.c (external_to_device_instance) : Ditto but for ihandle
3593 and device instance.
3594 * device.c (device_instance_to_external) : Ditto
3595
3596 * Makefile (device.o): Add dependency on cap.
3597
3598 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3599 needing to translate between internal and external representations
3600 changed to use the external_to_device et.al. device operations.
3601 * emul_chirp.c (chirp_emul_*) : Ditto
3602
3603 * Makefile (emul_chirp.o): Remove dependency on cap

3611
3612 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3613 read/write calls for buffer transfers. This will cause a fault to
3614 occure if the transfer fails. CHRP catches the fault while the
3615 others suffer the consequences.

3625 return from a client service call.
3626
3627 * emul_chirp.c (services): Add all OpenBoot services to table.

3629 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3630 (emul_chirp_create) : Use names instead of numbers for
3631 instructions being stored in memory.
