434 2001-10-25 Andrew Cagney <ac131313@redhat.com>
435
436 * emul_generic.c (OEA_MEMORY_SIZE): Increase to 4mb.
437 * hw_htab.c (htab_map_binary): Don't try to map the text section
438 when it is empty.
439 * emul_chirp.c (map_over_chirp_note): Default load-base to -1 not
440 CHIRP_LOAD_BASE.
441 (emul_chirp_create): Map in the interrupt table.
442

468
469 * sim-endian.h: Don't have parameters on macro definitions which
470 are simply renaming functions, to permit use of XCONCAT2 in both
471 the macro name and the arguments in a use of such a definition.
472
473 2000-11-15 Jim Blandy <jimb@redhat.com>
474
475 * sim_calls.c: Doc fix.
476 (sim_fetch_register, sim_store_register): Call
477 gdbarch_register_name directly, instead of going through
478 REGISTER_NAME macro.

480 2000-10-24 Geoff Keating <geoffk@cygnus.com>
481
482 * ppc-instructions (lfsux): Correct XO field of lfsux instruction.
483
484 Tue May 23 21:39:23 2000 Andrew Cagney <cagney@b1.cygnus.com>
485
486 * configure: Regenerated to track ../common/aclocal.m4 changes.
487
488 Fri Apr 28 15:59:27 2000 Andrew Cagney <cagney@b1.cygnus.com>
489
490 * events.c (event_queue_process): Call update_time_from_event
491 every time an event is removed from the queue.
492 (update_time_from_event): Delete assertion that a negative
493 time_from_event implies an empty event queue.
494
495 Fri Apr 28 15:53:54 2000 Andrew Cagney <cagney@b1.cygnus.com>

506
507 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
508
509 * configure: Regenerated to track ../common/aclocal.m4 changes.
510
511 1999-05-08 Felix Lee <flee@cygnus.com>
512
513 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
514 * configure: Regenerated to track ../common/aclocal.m4 changes.
515
516 1999-04-02 Keith Seitz <keiths@cygnus.com>
517
518 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
519 the frequency at which the poll_quit callback is called.
520 (poll_quit_count): New global.
521 (sim_io_poll_quit): Only call the poll_quit callback
522 after the specified POLL_QUIT_INTERVAL.
523
524 1999-02-22 Jim Lemke <jlemke@cygnus.com>
525
526 * dc-complex: Force expansion on all bits of field BO.
527 Previously, the least-significant (prediction) bit was ignored.
528 * ppc-instructions (conditional branches): Implement mpc860c0 option.
529 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
530 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
531 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
532 * interrupts.c (program_interrupt): Added handling for above interrupt.
533
534 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
535
536 Make the simulator compatible with the MPC750. It would be nicer
537 to make this a real multi-sim, but that's more work than we have
538 time for.
539 * emul_generic.c (emul_add_tree_options): Only require strict
540 alignment if it was explicitly requested at configuration time.
541 Don't make it the default for little-endian machines.
542 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
543 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
544 THRM2, THRM3): Plop in the MPC750 SPR registers.
545 (DABR): This is weird. This was HID5, but the PPC spec says this
546 should be DABR; why did some random processor use it for something
547 else? The HID5 entry dates back to the original checkin of the
548 simulator code in 1995, so remove it.
549 * sim_calls.c (register_names): Delete this; since the user can
550 now change GDB's list of register names dynamically, we can't
551 pretend there's a static mapping here.
552 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
553 function to get the register name. That ought to be accurate.
554 However, we're changing a compile-time dependency (using the
555 REGISTER_NAMES macro) into a link- and run-time dependency
556 (calling REGISTER_NAME, which happens to be a function call on the
557 PPC).
558
559 1999-01-22 Jim Lemke <jlemke@cygnus.com>
560
561 * igen.c(gen_semantics_[ch]): setup/use of new option
562 (-o mpc860c0[=n]).

564 ppc-instructions(the four branch insn groups): detect problematic br's.
565 psim.c(is_num - added, psim_options): Parse and init new option.
566 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
567
568 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
569
570 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

580 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
581 poll the external environment.
582
583 1998-11-19 Michael Meissner <meissner@cygnus.com>
584
585 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
586 fractional type, so that quiet NaN's aren't treated like
587 Infinities.
588
589 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
590
591 * table.c (table_open): For cygwin hosts, we need to use the
592 return value from the read routine as the number of bytes to
593 process. This apparently is due to text-mode vs binary-mode. If
594 the mounts are done text-mode, then the size returnedby fstat()
595 may be different than the number of bytes "read" in text mode.
596
597 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
598
599 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

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

620 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
621
622 * Makefile.in: The run target depended on a target psim$(EXEEXT),
623 but there was no such target, only plain psim. So I changed the
624 run target to depend on psim.
625
626 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
627
628 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
629 now defined in ../common/aclocal.m4, and the double definition causes
630 problems with AC_SUBST of EXEEXT.

929 * main.c ({cntrl_c,main}): Use RETSIGTYPE for signal return type,
930 don't assume void.
931 * sim_calls.c (sim_{ctrl_c,resume}): Ditto.
932
933 * Makefile.in (callback.o): Define HAVE_CONFIG_H, so callback.c
934 includes our config.h.
935
936 Tue Feb 4 13:42:59 1997 Doug Evans <dje@canuck.cygnus.com>
937
938 * configure.in: Fix typo in test for callback.c.

953 (device_add_ihandle_runtime_property): Update.
954

960
961 * gen-icache.c (print_icache_extraction): Add a reason parameter.
962 Augment each extracted field with a comment citing the codes
963 origin. Should simplify tracking down incorrect cache
964 extractions.
965

967
968 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
969 works for normal and boolean table entries.
970
971 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now

987
988 * gen-idecode.c: Re-work the table lookup code so that it assumes
989 that the entry is a leaf by default. Simplify the boolean table
990 entry code so that it involves a mask + test instead of shift +
991 shift + mask + test.
992
993 * gen-idecode.c: Correct generated igen body so that it no drops
994 or doubles clock interrupts.
995
996
997 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1023 fields.
1024
1025 * misc.c (name2i): Possibly abort if an invalid name is
1026 encountered.
1027 * ld-decode.c: Abort if the table type isn't found.

1029 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1030
1031 * When performance monitoring is disabled, it is still possible to
1032 determine the simulation speed by looking at the number of elapsed
1033 ticks recorded by the event queue.
1034
1035 * psim.c (psim_write_register, psim_read_register): Force the cpu
1036 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1037 next cpu would be zero any way.
1038
1039 * mon.c (mon_print_info): If possible, print the system cycle
1040 performance. This is an indication of the number of instructions
1041 per second.
1042
1043 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1044
1045 * The code to allow an event queue to be updated during a signal
1046 was missing. For main.c, a cntrl-c simulation termination wasn't
1047 handled cleanly.
1048
1049 * The simulation would not correctly restart if an event requested
1050 that the simulation be halted.
1051
1052 * psim.c (psim_options): Add hack to -i option to optionally
1053 include a level vis -i2.
1054 (psim_usage): Document.
1055
1056 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
1057 cntrl-c occures schedule an event to halt the simulation.

1059
1060 * events.c (event_queue_process): Mask interrupts while

1066 the processing state when processing has started. Adjust code
1067 so that it is tolerant of halts.
1068 (event_queue_init): Start the event queue out with processing
1069 false.
1070 (event_queue_tick): Check that processing isn't still being
1071 performed.
1072
1073 * gen-idecode.c (print_run_until_stop_body): Call
1074 event_queue_process_events to clear possibly pending events before
1075 starting a simulation run. Re-arange main loop so that simulator
1076 is correctly restarted when an event halts the simulation.

1078 * psim.c (psim_halt): Handle an event halting the simulation.
1079 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1080 reworked idecode.
1081
1082 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1083
1084 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1085 RA. Based on instruction frequency stats, expand additional
1086 instructions.
1087 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1088
1089 * ppc-opcode-stupid: Move all but the basic table in -complex into
1090 here. Update to new format.
1091
1092 * Makefile.in (tmp-defines): New target. Force defines.h to always
1093 be built. Hence get ppc-opcode-goto to build.
1094
1095 Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1096
1097 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1098 Implement.
1099
1100 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1101
1102 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1103 to be initialized independant of the rest of the simulation
1104 initalization. Otherwize a trace option explictly set from gdb
1105 could be overridden by hw_trace.
1106
1107 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1108
1109 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1110 debug.c. It could be much simpler.
1111
1112 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1113
1114 * Some devices support removable media. Add hooks to the disk
1115 device so that it supports this.

1125 media. If no file image is specified, use the next one in the
1126 image property list.
1127 (hw_disk_init_address): Change the file property so that it is a
1128 string array - use the first entry for the initial file image.
1129
1130 * tree.c (print_string_aray_property): New function - print a
1131 string array.
1132 (print_properties): Adjust.
1133 (print_string): Write a string, handling double quotes.

1143
1144 Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1145
1146 * For expressions like (RA == 0) that are entered in to the cache
1147 as RA_is_0. If possible generate the result of the expression so
1148 that the compiler gets a better chance of eliminating dead
1149 branches.
1150
1151 * gen-icache.c (print_icache_extraction): For a cache entry of
1152 the form <name>_is_<const> where it is a boolean field, generate
1153 the result of the expression instead of the expression its self.
1154 (print_icache_body): Remove code that was looking for *_is_0 and
1155 then generating corresponding definitions.
1156
1157 * gen-icache.c (print_icache_struct): If there is no cache, do not
1158 output expressions in idecode.h file.
1159
1160 * gen-icache.c (print_icache_body): Output them here.
1161
1162 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1163 expansion.

1167 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1168
1169 * The code that put values in and extracted values from the cache
1170 was too compilicated. The cache table did not allow values to be
1171 computed from cache entries. #defines could only be used when a
1172 cache was present, remove the restriction.
1173
1174 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1175 scratch variable is defined when a cache entry is beinf
1176 filled. Change the definition of a COMPUTE variable to be defined
1177 when the cache entry is being used.
1178 * gen-icache.c: Update.
1179
1180 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1181 is more obvious. old_name->field_name, new_name->derived_name.
1182 * gen-icache.c: Update
1183
1184 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1185 different types of cache code - put into cache, extract from
1186 cache, no cache - an explicit argument to print_icache_body.
1187 * gen-icache.c (print_icache_extraction): Ditto.
1188
1189 * gen-semantics.c (print_c_semantic): Update use.
1190 * gen-idecode.c (print_jump_insn): Update use.
1191 * gen-icache.c (print_icache_function): Update use.
1192
1193 * igen.c (main): Change 'R' option so that it does not force the
1194 cache.
1195
1196 * configure.in (enable-sim-icache): Clarify description. Make
1197 #define one of the defaults regardless of the cache. Probably
1198 should revamp and add a separate option.
1199
1200 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1201

1210 Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1211
1212 * The cap object was retaining a reference to the instance of a
1213 device after it was deleted. Instead add and remove cap's from the
1214 cap db as they are created and deleted. This ensuring that a
1215 capibility is only used during the lifetime of the corresponding
1216 object.
1217
1218 * cap.h, cap.c: Correct cap type - was signed32 should be
1219 signed_cell.
1220
1221 * cap.c (cap_add, cap_remove): New methods for cap object that
1222 allow the explicit addition and removal of internal objects that
1223 the cap knows about.
1224
1225 * cap.c (cap_init): Rewrite. Verify that the only objects
1226 remaining in the cap data base are those that were entered first.
1227 Thse objects will be the permenant ones.
1228 * device.c (device_init_address): Remember to initialize the cap
1229 database.
1230
1231 * device.c (device_create_instance_from): Explicitly add device

1250
1251 * The memory "claim" and "release" methods take an address and
1252 size as arguments. These may be multi cell values. Initially fix
1253 the memory code so that they check/detect this. Leave the
1254 adjustment of any clients to later.
1255
1256 * hw_memory.c (hw_memory_instance_claim,
1257 hw_memory_instance_release): Handle multi-cell memory devices.

1263
1264 * device.h, device.c (device_instance_call_method): Correct return
1265 type - can return either 0 or -1, hence should be a signed type.

1281 not made inline.
1282
1283 * hw_init.c (update_for_binary_section): Fix failure to allocate
1284 memory used by the binary in real-mode executions. If "claim"

2476
2477 * std-config.h (SEMANTICS_INLINE): By default, mask out the
2478 inlining of semantic functions from DEFAULT_INLINE. Almost all

2483
2484 Thu Jul 25 20:07:30 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

2510 always update the cache_entries semantic and address fields.
2511
2512 * gen-idecode.c (print_idecode_switch_illegal): Include a break
2513 when generating illegal instructions. This was commented out
2514 which is a hangover from looking a at switch statements generated
2515 using indirect jumps.
2516

2527 modules that include it.
2528 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2529 same as cpu.[hc].
2530
2531 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2532 name for a lable and then branch to it.
2533
2534 * ppc-instructions (convert_to_integer, Floating Round to
2535 Single-Precision, Floating Convert from Integer Doubleword): Use
2536 LABEL and GOTO instead of the recently added switch statements.
2537

2557
2558 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
2559 hardware instead of checking it using ls. configure.in should
2560 have taken care of any problems.
2561 (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
2562
2563 Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
2564
2565 * psim.c (psim_options): Enter the argument to the memory size
2566 option directly into the device tree. Was using atol() which is

2602
2603 * gen-idecode.c: Output the complete run_until_stop function

2606
2607 * std-config.h: Change psim.c so that it isn't inlined (as this is
2608 no longer needed).
2609
2610 * psim.c (run_until_stop): Delete the old run_until_stop function
2611 instead calling the idecode_run and idecode_run_until_stop
2612 functions that gen-idecode.c is now creating.
2613
2614 Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2615
2616 * dgen.c: Maintenance - update to use new features found in lf.c.

2639 corresponding call to ITRACE so that it still matches.
2640
2641 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead

2646
2647 * gen-idecode.c (print_jump_until_stop_body): New function and
2648 idecode generation option. Instead of generating and calling

2662 testing jumping idecodes.
2663

2671
2672 * configure.in (--enable-sim-icache): Accept an option list such

2674 will cause igen to generate instruction decode functions that
2675 include the corresponding semantic code.
2676
2677 Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2678
2679 * configure.in: New option --enable-sim-line-nr (default enabled).

3589
3590 * psim.c (psim_create): Update to handle above way of creating
3591 things. Extract all information from the device tree.
3592
3593 * device_tree.c (trace_*): New device node, its properties are
3594 used to set the value of the trace options. Init this device (in
3595 psim_options) when ever the options are updated.
3596
3597 Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
3598
3599 * debug.h: Add trace_print_info, trace_print_device_tree and
3600 trace_dump_device_tree. The first is a replacement for the
3601 variable `print_info' found in main.c and sim_calls.c. The latter
3602 two enable the dumping of the entire device tree.
3603
3604 * debug.c: Add to trace_description table.
3605
3606 * main.c (main): Use above trace instead of local variable
3607 * sim_calls.c (sim_close): Ditto
3608
3609 * device.c (device_tree_print_device): New. Prints the device
3610 tree in a format that is consistent with what can be parsed by the
3611 device tree load from file code.
3612
3613 * psim.c (psim_create): Dump device tree if enabled. If nump
3614 selected, exit psim immediatly.
3615
3616 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
3617
3618 * corefile-n.h (core_map_read_N): When mapping from an address to
3619 a device, do not subtract the devices base. The device its self
3620 can do this. Brings the behavour into line with OpenBoot.
3621 * corefile-n.h (core_map_write_N): Ditto
3622 * corefile.c (core_map_read_buffer): Ditto
3623 * corefile.c (core_map_write_buffer): Ditto

3628
3629 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
3630
3631 * device.c (attach_device_interrupt_edge): New. Interrupt model
3632 did not allow interrupts to be wired up as a general net (edges).
3633 Re-implement so that interrupt events can be passed to multiple
3634 controllers and interrupt controllers can further propogate
3635 interrupt events.
3636
3637 * device.c (attach_device_interrupt_edge) : New, Ditto
3638 * device.c (detach_device_interrupt_edge) : New, Ditto
3639 * device.c (clean_device_interrupt_edges) : New, Ditto
3640 * device.c (device_interrupt_event) : New, Ditto
3641 * device.c (device_interrupt_attach) : New, Ditto
3642 * device.c (device_interrupt_detach) : New, Ditto
3643 * device.c (device_child_interrupt_attach) : New, Ditto
3644 * device.c (device_child_interrupt_detach) : New, Ditto
3645
3646 * device.c (device_attach_interrupt) : Delete old
3647 * device.c (device_detach_interrupt) : Delete old
3648 * device.c (device_interrupt) : Delete old
3649 * device.c (device_interrupt_ack) : Delete old
3650
3651 * device_table.c (unimp_*) : Update to match
3652
3653 * device_table.c (icu_io_write_buffer_callback) : Update to use
3654 interface.
3655 * device_table.c (icu_interrupt_event_callback) : Ditto
3656
3657 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3658
3659 * device.c (external_to_device) : New function that provides a
3660 standard mapping between a devices internal representation (a
3661 pointer) and its external (or what is passed to a client)
3662 representation (a phandle). Implement using the cap object
3663 attached to the root node.
3664
3665 * device.c (device_to_external) : Ditto
3666 * device.c (external_to_device_instance) : Ditto but for ihandle
3667 and device instance.
3668 * device.c (device_instance_to_external) : Ditto
3669
3670 * Makefile (device.o): Add dependency on cap.
3671
3672 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3673 needing to translate between internal and external representations
3674 changed to use the external_to_device et.al. device operations.
3675 * emul_chirp.c (chirp_emul_*) : Ditto
3676
3677 * Makefile (emul_chirp.o): Remove dependency on cap

3682 on OpenBoot note section.
3683
3684 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3685
3686 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3687 read/write calls for buffer transfers. This will cause a fault to
3688 occure if the transfer fails. CHRP catches the fault while the
3689 others suffer the consequences.
3690 (emul_read_buffer): Ditto.
3691 (emul_write_word): Ditto.
3692 (emul_read_word): Ditto.

3698 emul_generic (emul_blr_instruction): Use a real blr instruction to
3699 return from a client service call.
3700
3701 * emul_chirp.c (services): Add all OpenBoot services to table.
3702
3703 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3704 (emul_chirp_create) : Use names instead of numbers for
3705 instructions being stored in memory.
3706
3707 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3708
