435
436 * sim-endian.h: Don't have parameters on macro definitions which
437 are simply renaming functions, to permit use of XCONCAT2 in both

485 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
486 the frequency at which the poll_quit callback is called.
487 (poll_quit_count): New global.
488 (sim_io_poll_quit): Only call the poll_quit callback
489 after the specified POLL_QUIT_INTERVAL.
490

502
503 Make the simulator compatible with the MPC750. It would be nicer
504 to make this a real multi-sim, but that's more work than we have
505 time for.
506 * emul_generic.c (emul_add_tree_options): Only require strict
507 alignment if it was explicitly requested at configuration time.
508 Don't make it the default for little-endian machines.
509 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
510 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
511 THRM2, THRM3): Plop in the MPC750 SPR registers.
512 (DABR): This is weird. This was HID5, but the PPC spec says this
513 should be DABR; why did some random processor use it for something
514 else? The HID5 entry dates back to the original checkin of the
515 simulator code in 1995, so remove it.
516 * sim_calls.c (register_names): Delete this; since the user can
517 now change GDB's list of register names dynamically, we can't
518 pretend there's a static mapping here.
519 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
520 function to get the register name. That ought to be accurate.
521 However, we're changing a compile-time dependency (using the
522 REGISTER_NAMES macro) into a link- and run-time dependency
523 (calling REGISTER_NAME, which happens to be a function call on the
524 PPC).
525
5261999-01-22 Jim Lemke <jlemke@cygnus.com>
527
528 * igen.c(gen_semantics_[ch]): setup/use of new option
529 (-o mpc860c0[=n]).

531 ppc-instructions(the four branch insn groups): detect problematic br's.
532 psim.c(is_num - added, psim_options): Parse and init new option.
533 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

552 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
553 fractional type, so that quiet NaN's aren't treated like
554 Infinities.
555
556Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
557
558 * table.c (table_open): For cygwin hosts, we need to use the
559 return value from the read routine as the number of bytes to
560 process. This apparently is due to text-mode vs binary-mode. If
561 the mounts are done text-mode, then the size returnedby fstat()
562 may be different than the number of bytes "read" in text mode.
563
564Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>

588
589 * Makefile.in: The run target depended on a target psim$(EXEEXT),
590 but there was no such target, only plain psim. So I changed the
591 run target to depend on psim.
592
593Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
594
595 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
596 now defined in ../common/aclocal.m4, and the double definition causes
597 problems with AC_SUBST of EXEEXT.

953 max iterations exceeded.
954
955 * gen-idecode.c: Re-work the table lookup code so that it assumes
956 that the entry is a leaf by default. Simplify the boolean table
957 entry code so that it involves a mask + test instead of shift +
958 shift + mask + test.
959
960 * gen-idecode.c: Correct generated igen body so that it no drops
961 or doubles clock interrupts.
962
963

1001
1002 * psim.c (psim_write_register, psim_read_register): Force the cpu
1003 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1004 next cpu would be zero any way.

1007 performance. This is an indication of the number of instructions
1008 per second.
1009
1010Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1011
1012 * The code to allow an event queue to be updated during a signal
1013 was missing. For main.c, a cntrl-c simulation termination wasn't
1014 handled cleanly.
1015
1016 * The simulation would not correctly restart if an event requested
1017 that the simulation be halted.
1018
1019 * psim.c (psim_options): Add hack to -i option to optionally
1020 include a level vis -i2.
1021 (psim_usage): Document.
1022

1035 (event_queue_init): Start the event queue out with processing
1036 false.
1037 (event_queue_tick): Check that processing isn't still being
1038 performed.
1039
1040 * gen-idecode.c (print_run_until_stop_body): Call
1041 event_queue_process_events to clear possibly pending events before

1045 * psim.c (psim_halt): Handle an event halting the simulation.
1046 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1047 reworked idecode.
1048
1049Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1050
1051 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1052 RA. Based on instruction frequency stats, expand additional
1053 instructions.
1054 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1055
1056 * ppc-opcode-stupid: Move all but the basic table in -complex into
1057 here. Update to new format.
1058
1059 * Makefile.in (tmp-defines): New target. Force defines.h to always
1060 be built. Hence get ppc-opcode-goto to build.
1061
1062Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1063
1064 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1065 Implement.
1066
1067Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1068
1069 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1070 to be initialized independant of the rest of the simulation
1071 initalization. Otherwize a trace option explictly set from gdb
1072 could be overridden by hw_trace.
1073
1074 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1075
1076 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1077 debug.c. It could be much simpler.
1078
1079Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1080
1081 * Some devices support removable media. Add hooks to the disk

1093 image property list.
1094 (hw_disk_init_address): Change the file property so that it is a
1095 string array - use the first entry for the initial file image.
1096
1097 * tree.c (print_string_aray_property): New function - print a
1098 string array.
1099 (print_properties): Adjust.

1110
1111Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1112
1113 * For expressions like (RA == 0) that are entered in to the cache
1114 as RA_is_0. If possible generate the result of the expression so
1115 that the compiler gets a better chance of eliminating dead
1116 branches.
1117
1118 * gen-icache.c (print_icache_extraction): For a cache entry of
1119 the form <name>_is_<const> where it is a boolean field, generate
1120 the result of the expression instead of the expression its self.
1121 (print_icache_body): Remove code that was looking for *_is_0 and
1122 then generating corresponding definitions.
1123
1124 * gen-icache.c (print_icache_struct): If there is no cache, do not
1125 output expressions in idecode.h file.
1126
1127 * gen-icache.c (print_icache_body): Output them here.
1128
1129 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1130 expansion.

1134Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1135
1136 * The code that put values in and extracted values from the cache
1137 was too compilicated. The cache table did not allow values to be
1138 computed from cache entries. #defines could only be used when a
1139 cache was present, remove the restriction.
1140
1141 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1142 scratch variable is defined when a cache entry is beinf
1143 filled. Change the definition of a COMPUTE variable to be defined
1144 when the cache entry is being used.
1145 * gen-icache.c: Update.
1146
1147 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1148 is more obvious. old_name->field_name, new_name->derived_name.
1149 * gen-icache.c: Update
1150
1151 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1152 different types of cache code - put into cache, extract from
1153 cache, no cache - an explicit argument to print_icache_body.
1154 * gen-icache.c (print_icache_extraction): Ditto.
1155
1156 * gen-semantics.c (print_c_semantic): Update use.
1157 * gen-idecode.c (print_jump_insn): Update use.
1158 * gen-icache.c (print_icache_function): Update use.

1160 * igen.c (main): Change 'R' option so that it does not force the
1161 cache.
1162
1163 * configure.in (enable-sim-icache): Clarify description. Make
1164 #define one of the defaults regardless of the cache. Probably
1165 should revamp and add a separate option.
1166
1167Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1168

1177Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1178
1179 * The cap object was retaining a reference to the instance of a
1180 device after it was deleted. Instead add and remove cap's from the
1181 cap db as they are created and deleted. This ensuring that a
1182 capibility is only used during the lifetime of the corresponding
1183 object.
1184
1185 * cap.h, cap.c: Correct cap type - was signed32 should be
1186 signed_cell.
1187
1188 * cap.c (cap_add, cap_remove): New methods for cap object that
1189 allow the explicit addition and removal of internal objects that
1190 the cap knows about.
1191
1192 * cap.c (cap_init): Rewrite. Verify that the only objects
1193 remaining in the cap data base are those that were entered first.
1194 Thse objects will be the permenant ones.
1195 * device.c (device_init_address): Remember to initialize the cap
1196 database.

1217
1218 * The memory "claim" and "release" methods take an address and
1219 size as arguments. These may be multi cell values. Initially fix
1220 the memory code so that they check/detect this. Leave the
1221 adjustment of any clients to later.
1222
1223 * hw_memory.c (hw_memory_instance_claim,
1224 hw_memory_instance_release): Handle multi-cell memory devices.

1230
1231 * device.h, device.c (device_instance_call_method): Correct return
1232 type - can return either 0 or -1, hence should be a signed type.

2443
2444 * std-config.h (SEMANTICS_INLINE): By default, mask out the
2445 inlining of semantic functions from DEFAULT_INLINE. Almost all

2477 always update the cache_entries semantic and address fields.
2478
2479 * gen-idecode.c (print_idecode_switch_illegal): Include a break

2494 modules that include it.
2495 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2496 same as cpu.[hc].
2497
2498 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2499 name for a lable and then branch to it.
2500
2501 * ppc-instructions (convert_to_integer, Floating Round to
2502 Single-Precision, Floating Convert from Integer Doubleword): Use
2503 LABEL and GOTO instead of the recently added switch statements.

2526 hardware instead of checking it using ls. configure.in should
2527 have taken care of any problems.
2528 (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
2529
2530Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
2531
2532 * psim.c (psim_options): Enter the argument to the memory size
2533 option directly into the device tree. Was using atol() which is

2569
2570 * gen-idecode.c: Output the complete run_until_stop function

2573
2574 * std-config.h: Change psim.c so that it isn't inlined (as this is
2575 no longer needed).
2576
2577 * psim.c (run_until_stop): Delete the old run_until_stop function
2578 instead calling the idecode_run and idecode_run_until_stop
2579 functions that gen-idecode.c is now creating.

2613
2614 * gen-idecode.c (print_jump_until_stop_body): New function and
2615 idecode generation option. Instead of generating and calling

2629 testing jumping idecodes.
2630

2644Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2645
2646 * configure.in: New option --enable-sim-line-nr (default enabled).

3556
3557 * psim.c (psim_create): Update to handle above way of creating
3558 things. Extract all information from the device tree.
3559
3560 * device_tree.c (trace_*): New device node, its properties are
3561 used to set the value of the trace options. Init this device (in
3562 psim_options) when ever the options are updated.
3563
3564Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
3565
3566 * debug.h: Add trace_print_info, trace_print_device_tree and
3567 trace_dump_device_tree. The first is a replacement for the
3568 variable `print_info' found in main.c and sim_calls.c. The latter
3569 two enable the dumping of the entire device tree.
3570
3571 * debug.c: Add to trace_description table.
3572
3573 * main.c (main): Use above trace instead of local variable
3574 * sim_calls.c (sim_close): Ditto
3575
3576 * device.c (device_tree_print_device): New. Prints the device
3577 tree in a format that is consistent with what can be parsed by the
3578 device tree load from file code.
3579
3580 * psim.c (psim_create): Dump device tree if enabled. If nump
3581 selected, exit psim immediatly.
3582
3583Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
3584
3585 * corefile-n.h (core_map_read_N): When mapping from an address to
3586 a device, do not subtract the devices base. The device its self
3587 can do this. Brings the behavour into line with OpenBoot.
3588 * corefile-n.h (core_map_write_N): Ditto
3589 * corefile.c (core_map_read_buffer): Ditto
3590 * corefile.c (core_map_write_buffer): Ditto

3595
3596Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
3597
3598 * device.c (attach_device_interrupt_edge): New. Interrupt model
3599 did not allow interrupts to be wired up as a general net (edges).
3600 Re-implement so that interrupt events can be passed to multiple
3601 controllers and interrupt controllers can further propogate
3602 interrupt events.
3603
3604 * device.c (attach_device_interrupt_edge) : New, Ditto
3605 * device.c (detach_device_interrupt_edge) : New, Ditto
3606 * device.c (clean_device_interrupt_edges) : New, Ditto
3607 * device.c (device_interrupt_event) : New, Ditto
3608 * device.c (device_interrupt_attach) : New, Ditto
3609 * device.c (device_interrupt_detach) : New, Ditto
3610 * device.c (device_child_interrupt_attach) : New, Ditto
3611 * device.c (device_child_interrupt_detach) : New, Ditto
3612
3613 * device.c (device_attach_interrupt) : Delete old
3614 * device.c (device_detach_interrupt) : Delete old
3615 * device.c (device_interrupt) : Delete old
3616 * device.c (device_interrupt_ack) : Delete old
3617
3618 * device_table.c (unimp_*) : Update to match
3619
3620 * device_table.c (icu_io_write_buffer_callback) : Update to use
3621 interface.
3622 * device_table.c (icu_interrupt_event_callback) : Ditto
3623
3624Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3625
3626 * device.c (external_to_device) : New function that provides a
3627 standard mapping between a devices internal representation (a
3628 pointer) and its external (or what is passed to a client)
3629 representation (a phandle). Implement using the cap object
3630 attached to the root node.
3631
3632 * device.c (device_to_external) : Ditto
3633 * device.c (external_to_device_instance) : Ditto but for ihandle
3634 and device instance.
3635 * device.c (device_instance_to_external) : Ditto
3636
3637 * Makefile (device.o): Add dependency on cap.
3638
3639 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3640 needing to translate between internal and external representations
3641 changed to use the external_to_device et.al. device operations.
3642 * emul_chirp.c (chirp_emul_*) : Ditto
3643
3644 * Makefile (emul_chirp.o): Remove dependency on cap

3649 on OpenBoot note section.
3650
3651Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3652
3653 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3654 read/write calls for buffer transfers. This will cause a fault to
3655 occure if the transfer fails. CHRP catches the fault while the
3656 others suffer the consequences.
3657 (emul_read_buffer): Ditto.
3658 (emul_write_word): Ditto.
3659 (emul_read_word): Ditto.
3660 (emul_read_string): Ditto.

3665 emul_generic (emul_blr_instruction): Use a real blr instruction to
3666 return from a client service call.
3667
3668 * emul_chirp.c (services): Add all OpenBoot services to table.
3669
3670 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3671 (emul_chirp_create) : Use names instead of numbers for
3672 instructions being stored in memory.
