431
432 * sim-endian.h: Don't have parameters on macro definitions which
433 are simply renaming functions, to permit use of XCONCAT2 in both
434 the macro name and the arguments in a use of such a definition.

482 the frequency at which the poll_quit callback is called.
483 (poll_quit_count): New global.
484 (sim_io_poll_quit): Only call the poll_quit callback
485 after the specified POLL_QUIT_INTERVAL.
486

488

499 Make the simulator compatible with the MPC750. It would be nicer
500 to make this a real multi-sim, but that's more work than we have
501 time for.
502 * emul_generic.c (emul_add_tree_options): Only require strict
503 alignment if it was explicitly requested at configuration time.
504 Don't make it the default for little-endian machines.
505 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
506 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
507 THRM2, THRM3): Plop in the MPC750 SPR registers.
508 (DABR): This is weird. This was HID5, but the PPC spec says this
509 should be DABR; why did some random processor use it for something
510 else? The HID5 entry dates back to the original checkin of the
511 simulator code in 1995, so remove it.
512 * sim_calls.c (register_names): Delete this; since the user can
513 now change GDB's list of register names dynamically, we can't
514 pretend there's a static mapping here.
515 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
516 function to get the register name. That ought to be accurate.
517 However, we're changing a compile-time dependency (using the
518 REGISTER_NAMES macro) into a link- and run-time dependency
519 (calling REGISTER_NAME, which happens to be a function call on the
520 PPC).
521
5221999-01-22 Jim Lemke <jlemke@cygnus.com>
523
524 * igen.c(gen_semantics_[ch]): setup/use of new option

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

549 fractional type, so that quiet NaN's aren't treated like
550 Infinities.
551
552Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
553
554 * table.c (table_open): For cygwin hosts, we need to use the
555 return value from the read routine as the number of bytes to
556 process. This apparently is due to text-mode vs binary-mode. If
557 the mounts are done text-mode, then the size returnedby fstat()
558 may be different than the number of bytes "read" in text mode.

584
585 * Makefile.in: The run target depended on a target psim$(EXEEXT),
586 but there was no such target, only plain psim. So I changed the
587 run target to depend on psim.
588
589Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
590
591 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are

949 max iterations exceeded.
950
951 * gen-idecode.c: Re-work the table lookup code so that it assumes
952 that the entry is a leaf by default. Simplify the boolean table
953 entry code so that it involves a mask + test instead of shift +
954 shift + mask + test.
955
956 * gen-idecode.c: Correct generated igen body so that it no drops
957 or doubles clock interrupts.
958
959

996 ticks recorded by the event queue.
997
998 * psim.c (psim_write_register, psim_read_register): Force the cpu
999 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1000 next cpu would be zero any way.

1003 performance. This is an indication of the number of instructions
1004 per second.
1005
1006Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1007
1008 * The code to allow an event queue to be updated during a signal
1009 was missing. For main.c, a cntrl-c simulation termination wasn't
1010 handled cleanly.
1011
1012 * The simulation would not correctly restart if an event requested
1013 that the simulation be halted.
1014
1015 * psim.c (psim_options): Add hack to -i option to optionally
1016 include a level vis -i2.
1017 (psim_usage): Document.
1018

1030 so that it is tolerant of halts.
1031 (event_queue_init): Start the event queue out with processing
1032 false.
1033 (event_queue_tick): Check that processing isn't still being
1034 performed.
1035
1036 * gen-idecode.c (print_run_until_stop_body): Call
1037 event_queue_process_events to clear possibly pending events before

1041 * psim.c (psim_halt): Handle an event halting the simulation.
1042 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1043 reworked idecode.
1044
1045Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1046
1047 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1048 RA. Based on instruction frequency stats, expand additional
1049 instructions.
1050 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1051
1052 * ppc-opcode-stupid: Move all but the basic table in -complex into
1053 here. Update to new format.
1054
1055 * Makefile.in (tmp-defines): New target. Force defines.h to always
1056 be built. Hence get ppc-opcode-goto to build.
1057
1058Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1059
1060 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1061 Implement.
1062
1063Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1064
1065 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1066 to be initialized independant of the rest of the simulation
1067 initalization. Otherwize a trace option explictly set from gdb
1068 could be overridden by hw_trace.
1069
1070 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1071
1072 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1073 debug.c. It could be much simpler.
1074
1075Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1076
1077 * Some devices support removable media. Add hooks to the disk

1091 string array - use the first entry for the initial file image.
1092
1093 * tree.c (print_string_aray_property): New function - print a
1094 string array.
1095 (print_properties): Adjust.

1106
1107Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1108
1109 * For expressions like (RA == 0) that are entered in to the cache
1110 as RA_is_0. If possible generate the result of the expression so
1111 that the compiler gets a better chance of eliminating dead
1112 branches.
1113
1114 * gen-icache.c (print_icache_extraction): For a cache entry of
1115 the form <name>_is_<const> where it is a boolean field, generate
1116 the result of the expression instead of the expression its self.
1117 (print_icache_body): Remove code that was looking for *_is_0 and
1118 then generating corresponding definitions.
1119
1120 * gen-icache.c (print_icache_struct): If there is no cache, do not
1121 output expressions in idecode.h file.
1122
1123 * gen-icache.c (print_icache_body): Output them here.
1124
1125 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1126 expansion.

1130Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1131
1132 * The code that put values in and extracted values from the cache
1133 was too compilicated. The cache table did not allow values to be
1134 computed from cache entries. #defines could only be used when a
1135 cache was present, remove the restriction.
1136
1137 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1138 scratch variable is defined when a cache entry is beinf
1139 filled. Change the definition of a COMPUTE variable to be defined
1140 when the cache entry is being used.
1141 * gen-icache.c: Update.
1142

1146
1147 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1148 different types of cache code - put into cache, extract from
1149 cache, no cache - an explicit argument to print_icache_body.
1150 * gen-icache.c (print_icache_extraction): Ditto.
1151
1152 * gen-semantics.c (print_c_semantic): Update use.
1153 * gen-idecode.c (print_jump_insn): Update use.
1154 * gen-icache.c (print_icache_function): Update use.

1156 * igen.c (main): Change 'R' option so that it does not force the
1157 cache.
1158
1159 * configure.in (enable-sim-icache): Clarify description. Make
1160 #define one of the defaults regardless of the cache. Probably
1161 should revamp and add a separate option.
1162
1163Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1164

1173Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1174
1175 * The cap object was retaining a reference to the instance of a
1176 device after it was deleted. Instead add and remove cap's from the
1177 cap db as they are created and deleted. This ensuring that a
1178 capibility is only used during the lifetime of the corresponding
1179 object.
1180
1181 * cap.h, cap.c: Correct cap type - was signed32 should be
1182 signed_cell.
1183
1184 * cap.c (cap_add, cap_remove): New methods for cap object that
1185 allow the explicit addition and removal of internal objects that
1186 the cap knows about.
1187
1188 * cap.c (cap_init): Rewrite. Verify that the only objects
1189 remaining in the cap data base are those that were entered first.
1190 Thse objects will be the permenant ones.
1191 * device.c (device_init_address): Remember to initialize the cap
1192 database.

1213
1214 * The memory "claim" and "release" methods take an address and
1215 size as arguments. These may be multi cell values. Initially fix
1216 the memory code so that they check/detect this. Leave the
1217 adjustment of any clients to later.
1218

1226
1227 * device.h, device.c (device_instance_call_method): Correct return

2439
2440 * std-config.h (SEMANTICS_INLINE): By default, mask out the

2473 always update the cache_entries semantic and address fields.
2474
2475 * gen-idecode.c (print_idecode_switch_illegal): Include a break

2490 modules that include it.
2491 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2492 same as cpu.[hc].
2493
2494 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2495 name for a lable and then branch to it.
2496
2497 * ppc-instructions (convert_to_integer, Floating Round to
2498 Single-Precision, Floating Convert from Integer Doubleword): Use
2499 LABEL and GOTO instead of the recently added switch statements.

2525
2526Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
2527
2528 * psim.c (psim_options): Enter the argument to the memory size

2565
2566 * gen-idecode.c: Output the complete run_until_stop function

2569
2570 * std-config.h: Change psim.c so that it isn't inlined (as this is
2571 no longer needed).
2572
2573 * psim.c (run_until_stop): Delete the old run_until_stop function
2574 instead calling the idecode_run and idecode_run_until_stop
2575 functions that gen-idecode.c is now creating.

2609
2610 * gen-idecode.c (print_jump_until_stop_body): New function and
2611 idecode generation option. Instead of generating and calling

2625 testing jumping idecodes.
2626

2641
2642 * configure.in: New option --enable-sim-line-nr (default enabled).

3552
3553 * psim.c (psim_create): Update to handle above way of creating
3554 things. Extract all information from the device tree.
3555
3556 * device_tree.c (trace_*): New device node, its properties are
3557 used to set the value of the trace options. Init this device (in
3558 psim_options) when ever the options are updated.
3559
3560Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
3561
3562 * debug.h: Add trace_print_info, trace_print_device_tree and
3563 trace_dump_device_tree. The first is a replacement for the
3564 variable `print_info' found in main.c and sim_calls.c. The latter
3565 two enable the dumping of the entire device tree.
3566
3567 * debug.c: Add to trace_description table.
3568
3569 * main.c (main): Use above trace instead of local variable
3570 * sim_calls.c (sim_close): Ditto
3571
3572 * device.c (device_tree_print_device): New. Prints the device
3573 tree in a format that is consistent with what can be parsed by the
3574 device tree load from file code.
3575
3576 * psim.c (psim_create): Dump device tree if enabled. If nump
3577 selected, exit psim immediatly.
3578
3579Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
3580
3581 * corefile-n.h (core_map_read_N): When mapping from an address to
3582 a device, do not subtract the devices base. The device its self
3583 can do this. Brings the behavour into line with OpenBoot.
3584 * corefile-n.h (core_map_write_N): Ditto
3585 * corefile.c (core_map_read_buffer): Ditto
3586 * corefile.c (core_map_write_buffer): Ditto

3593
3594 * device.c (attach_device_interrupt_edge): New. Interrupt model
3595 did not allow interrupts to be wired up as a general net (edges).
3596 Re-implement so that interrupt events can be passed to multiple
3597 controllers and interrupt controllers can further propogate
3598 interrupt events.
3599
3600 * device.c (attach_device_interrupt_edge) : New, Ditto
3601 * device.c (detach_device_interrupt_edge) : New, Ditto
3602 * device.c (clean_device_interrupt_edges) : New, Ditto
3603 * device.c (device_interrupt_event) : New, Ditto
3604 * device.c (device_interrupt_attach) : New, Ditto
3605 * device.c (device_interrupt_detach) : New, Ditto
3606 * device.c (device_child_interrupt_attach) : New, Ditto
3607 * device.c (device_child_interrupt_detach) : New, Ditto
3608
3609 * device.c (device_attach_interrupt) : Delete old
3610 * device.c (device_detach_interrupt) : Delete old
3611 * device.c (device_interrupt) : Delete old
3612 * device.c (device_interrupt_ack) : Delete old
3613
3614 * device_table.c (unimp_*) : Update to match
3615
3616 * device_table.c (icu_io_write_buffer_callback) : Update to use
3617 interface.
3618 * device_table.c (icu_interrupt_event_callback) : Ditto
3619
3620Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3621
3622 * device.c (external_to_device) : New function that provides a
3623 standard mapping between a devices internal representation (a
3624 pointer) and its external (or what is passed to a client)
3625 representation (a phandle). Implement using the cap object
3626 attached to the root node.
3627
3628 * device.c (device_to_external) : Ditto
3629 * device.c (external_to_device_instance) : Ditto but for ihandle
3630 and device instance.
3631 * device.c (device_instance_to_external) : Ditto
3632
3633 * Makefile (device.o): Add dependency on cap.
3634
3635 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3636 needing to translate between internal and external representations
3637 changed to use the external_to_device et.al. device operations.
3638 * emul_chirp.c (chirp_emul_*) : Ditto
3639
3640 * Makefile (emul_chirp.o): Remove dependency on cap

3645 on OpenBoot note section.
3646
3647Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3648
3649 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3650 read/write calls for buffer transfers. This will cause a fault to
3651 occure if the transfer fails. CHRP catches the fault while the
3652 others suffer the consequences.
3653 (emul_read_buffer): Ditto.
3654 (emul_write_word): Ditto.
3655 (emul_read_word): Ditto.
3656 (emul_read_string): Ditto.

3661 emul_generic (emul_blr_instruction): Use a real blr instruction to
3662 return from a client service call.
3663
3664 * emul_chirp.c (services): Add all OpenBoot services to table.
3665
3666 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3667 (emul_chirp_create) : Use names instead of numbers for
3668 instructions being stored in memory.
