  32
  33 1999-04-02  Keith Seitz  <keiths@cygnus.com>
  34
  35         * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
  36         the frequency at which the poll_quit callback is called.

  38         (sim_io_poll_quit): Only call the poll_quit callback
  39         after the specified POLL_QUIT_INTERVAL.
  40
  41 1999-02-22  Jim Lemke  <jlemke@cygnus.com>
  42
  43         * dc-complex: Force expansion on all bits of field BO.

  50
  51 1999-02-01  Jim Blandy  <jimb@zwingli.cygnus.com>
  52
  53         Make the simulator compatible with the MPC750.  It would be nicer
  54         to make this a real multi-sim, but that's more work than we have
  55         time for.
  56         * emul_generic.c (emul_add_tree_options): Only require strict
  57         alignment if it was explicitly requested at configuration time.
  58         Don't make it the default for little-endian machines.
  59         * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
  60         MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
  61         THRM2, THRM3): Plop in the MPC750 SPR registers.
  62         (DABR): This is weird.  This was HID5, but the PPC spec says this
  63         should be DABR; why did some random processor use it for something
  64         else?  The HID5 entry dates back to the original checkin of the
  65         simulator code in 1995, so remove it.
  66         * sim_calls.c (register_names): Delete this; since the user can
  67         now change GDB's list of register names dynamically, we can't
  68         pretend there's a static mapping here.
  69         (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
  70         function to get the register name.  That ought to be accurate.
  71         However, we're changing a compile-time dependency (using the
  72         REGISTER_NAMES macro) into a link- and run-time dependency
  73         (calling REGISTER_NAME, which happens to be a function call on the
  74         PPC).
  75
  76 1999-01-22  Jim Lemke <jlemke@cygnus.com>
  77
  78         * igen.c(gen_semantics_[ch]): setup/use of new option
  79         (-o mpc860c0[=n]).
  80         interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
  81         ppc-instructions(the four branch insn groups): detect problematic br's.
  82         psim.c(is_num - added, psim_options): Parse and init new option.
  83         These changes are currently under #ifdef WITH_OPTION_MPC860C0.
  84
  85 1998-12-01  Ken Raeburn  <raeburn@cygnus.com>
  86
  87         * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.
  88
  89 Fri Nov 20 12:17:28 1998  Andrew Cagney  <cagney@b1.cygnus.com>
  90
  91         * main.c (sim_io_poll_quit): Stub function.
  92
  93         * events.c (SIM_EVENTS_POLL_RATE): Define.
  94         (sim_events_poll): Copy function from common/sim-events.c.
  95         (event_queue_init): Copy scheduling of sim_events_poll from same.
  96
  97         * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
  98         poll the external environment.
  99
 100 1998-11-19  Michael Meissner  <meissner@cygnus.com>
 101
 102         * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
 103         fractional type, so that quiet NaN's aren't treated like
 104         Infinities.
 105
 106 Mon Sep 28 09:42:45 1998  Drew Moseley  <dmoseley@cygnus.com>
 107
 108         * table.c (table_open): For cygwin hosts, we need to use the
 109         return value from the read routine as the number of bytes to
 110         process.  This apparently is due to text-mode vs binary-mode.  If
 111         the mounts are done text-mode, then the size returnedby fstat()
 112         may be different than the number of bytes "read" in text mode.
 113
 114 Sun Oct  4 00:50:47 1998  Felix Lee  <flee@cygnus.com>
 115
 116         * emul_netbsd.c (do_open): fix order-of-evaluation problem.

 124
 125 Mon Jun 29 10:57:36 1998  Michael Snyder  <msnyder@cleaver.cygnus.com>
 126
 127         * sim_calls.c (sim_fetch_register, sim_store_register):
 128         return zero when nothing to do.
 129
 130 1998-06-26  Michael Meissner  <meissner@cygnus.com>
 131
 132         * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
 133         * configure: Regenerate.
 134         * emul_{netbsd,unix}.c (toplevel): No longer try to include
 135         sys/mount.h. It conflicts on Linux when gnu libc2 is used.
 136
 137 Tue May 12 12:10:33 PDT 1998  James Ingham  <jingham@leda.cygnus.com>
 138
 139         * Makefile.in: The run target depended on a target psim$(EXEEXT),
 140         but there was no such target, only plain psim.  So I changed the
 141         run target to depend on psim.
 142
 143 Sat May  2 01:10:12 1998  Stu Grossman  <grossman@babylon-5.cygnus.com>
 144
 145         * aclocal.m4:  Remove defs of AM_EXEEXT and AM_CYGWIN32.  These are
 146         now defined in ../common/aclocal.m4, and the double definition causes
 147         problems with AC_SUBST of EXEEXT.
 148         * configure:  Regenerate.
 149
 150 Wed Apr 29 15:44:52 1998  Geoffrey Noer  <noer@cygnus.com>

 390
 391         * Makefile.in (targ-vals.def): Re-do rule so that it works with
 392         FreeBSD's make.  Didn't like $<.
 393

 416
 417 Wed Feb 12 19:33:45 1997  Andrew Cagney  <cagney@phydeaux.cygnus.com>
 418
 419         * Many of the ppc-opcode-* files are identical baring the type of
 420         lookup table.  Instead of having multiple tables, igen can do this
 421         via an additional option.
 422
 423         * ld-decode.h, ld-decode.c (force_decode_gen_type): New function,
 424         allow the type of generated table specified in the decode file to
 425         be overridden.
 426
 427         * ld-decode.c (load_decode_table): Allow the table type to be
 428         overridden.

 444         of sigprocmask to appropriate autoconf test.
 445
 446         * main.c ({cntrl_c,main}): Use RETSIGTYPE for signal return type,

 461         found in the device tree.
 462
 463 Wed Feb  5 10:56:27 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 464
 465         * Property create/initialization still wasn't correctly ordered.
 466         Should be delaying everything related to ihandle creation until
 467         after the rest of the tree has been established.
 468
 469         * device.c (device_find_ihandle_runtime_property): Update.

 479         Augment each extracted field with a comment citing the codes
 480         origin.  Should simplify tracking down incorrect cache
 481         extractions.
 482
 483 Tue Feb  4 17:44:51 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 484
 485         * gen-icache.c: Generalize code handling XXX_is_NNN so that it
 486         works for normal and boolean table entries.
 487
 488         * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
 489         valid.  Handle this just like *_{read,write}_register now handles
 490         it.
 491
 492 Mon Feb  3 17:18:16 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>

 499         * psim.c (psim_options): Add new option -c for max-iterations or
 500         count.

 502         (psim_max_iterations_exceeded): New function, abort simulation if
 503         max iterations exceeded.
 504
 505         * gen-idecode.c: Re-work the table lookup code so that it assumes
 506         that the entry is a leaf by default.  Simplify the boolean table
 507         entry code so that it involves a mask + test instead of shift +
 508         shift + mask + test.
 509
 510         * gen-idecode.c: Correct generated igen body so that it no drops
 511         or doubles clock interrupts.
 512
 513
 514 Thu Jan 30 11:23:20 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>

 521
 522 Wed Jan 29 12:32:41 1997  Michael Meissner  <meissner@tiktok.cygnus.com>
 523
 524         * configure.in (sim_callback): If the gdb is post 4.16, configure
 525         callback support from the common directory.
 526         * configure: Regenerate.
 527
 528         * Makefile.in (BUILT_SRC_WO_CONFIG): Add targ-vals.{h,def} and
 529         targ-map.c.
 530         (GDB_OBJ): Add callback support configured in.
 531         (gentmap,targ-vals.def): Build from common directory.
 532         (targ-vals.h,targ-map.c): Build by running gentmap.
 533         (callback.o): Build from source in common directory.

 537 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 538
 539         * igen wasn't aborting if the opcode table contained no valid
 540         fields.
 541
 542         * misc.c (name2i): Possibly abort if an invalid name is
 543         encountered.
 544         * ld-decode.c: Abort if the table type isn't found.
 545
 546 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 547
 548         * When performance monitoring is disabled, it is still possible to
 549         determine the simulation speed by looking at the number of elapsed
 550         ticks recorded by the event queue.
 551
 552         * psim.c (psim_write_register, psim_read_register): Force the cpu
 553         to zero when it is either of `-1' or `nr_cpus'.  In both cases the
 554         next cpu would be zero any way.
 555
 556         * mon.c (mon_print_info): If possible, print the system cycle
 557         performance.  This is an indication of the number of instructions
 558         per second.
 559
 560 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 561
 562         * The code to allow an event queue to be updated during a signal
 563         was missing.  For main.c, a cntrl-c simulation termination wasn't
 564         handled cleanly.
 565
 566         * The simulation would not correctly restart if an event requested
 567         that the simulation be halted.
 568
 569         * psim.c (psim_options): Add hack to -i option to optionally
 570         include a level vis -i2.
 571         (psim_usage): Document.
 572
 573         * main.c (cntrl_c, cntrl_c_simulation): New functions.  When a
 574         cntrl-c occures schedule an event to halt the simulation.
 575         (main): Catch CNTRL-C signals with the function cntrl_c.
 576
 577         * events.c (event_queue_process): Mask interrupts while
 578         manipulating the async event queue.
 579         (event_queue_init): Ditto.
 580         (event_queue_schedule_after_signal): Ditto.
 581
 582         * events.c (event_queue_process): Mark the event queue as being in
 583         the processing state when processing has started.  Adjust code
 584         so that it is tolerant of halts.
 585         (event_queue_init): Start the event queue out with processing
 586         false.
 587         (event_queue_tick): Check that processing isn't still being
 588         performed.
 589
 590         * gen-idecode.c (print_run_until_stop_body): Call
 591         event_queue_process_events to clear possibly pending events before
 592         starting a simulation run.  Re-arange main loop so that simulator
 593         is correctly restarted when an event halts the simulation.
 594
 595         * psim.c (psim_halt): Handle an event halting the simulation.
 596         * psim.c (psim_init): Adjust initial cpu - == -1 - to match
 597         reworked idecode.
 598
 599 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 600
 601         * ppc-opcode-complex: Correct typo - was expanding ORA instead of
 602         RA.  Based on instruction frequency stats, expand additional
 603         instructions.
 604         * ppc-instructions: Change all `RA == 0' to RA_is_0.
 605
 606         * ppc-opcode-stupid: Move all but the basic table in -complex into
 607         here.  Update to new format.
 608
 609         * Makefile.in (tmp-defines): New target. Force defines.h to always
 610         be built.  Hence get ppc-opcode-goto to build.
 611
 612 Tue Jan 28 13:00:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 613
 614         * hw_com.c (hw_com_instance_read, hw_com_instance_write):
 615         Implement.
 616
 617 Thu Jan 23 09:07:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 618
 619         * hw_trace.c (hw_trace_init_data): Delete.  The trace options need
 620         to be initialized independant of the rest of the simulation
 621         initalization.  Otherwize a trace option explictly set from gdb
 622         could be overridden by hw_trace.
 623
 624         * psim.c (psim_options): Clarify reason why the trace ioctl occures.
 625
 626         * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
 627         debug.c.  It could be much simpler.
 628
 629 Thu Jan 23 09:07:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 630
 631         * Some devices support removable media.  Add hooks to the disk
 632         device so that it supports this.
 633
 634         * device.c (device_add_string_array_property,
 635         device_find_string_array_property): New functions, manipulate
 636         properties containing an array of strings.
 637         (device_find_string_property): Allow a string array.
 638         (device_init_static_properties): Update.
 639         (device_init_runtime_properties): Update.
 640
 641         * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
 642         media.  If no file image is specified, use the next one in the
 643         image property list.
 644         (hw_disk_init_address): Change the file property so that it is a
 645         string array - use the first entry for the initial file image.
 646
 647         * tree.c (print_string_aray_property): New function - print a
 648         string array.
 649         (print_properties): Adjust.
 650         (print_string): Write a string, handling double quotes.
 651
 652         * device.h: Define an ioctl to `change-media' with an optional new
 653         media image.
 654
 655         * hw_disk.c: Allow floppy disk devices to be specified.
 656
 657         * psim.c (psim_command): New function, parse more complex psim
 658         commands such as "change-media" and "trace".
 659         * sim_calls.c (sim_do_command): Use.
 660
 661 Wed Jan 22 09:38:33 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 662
 663         * For expressions like (RA == 0) that are entered in to the cache
 664         as RA_is_0. If possible generate the result of the expression so
 665         that the compiler gets a better chance of eliminating dead
 666         branches.
 667
 668         * gen-icache.c (print_icache_extraction): For a cache entry of
 669         the form <name>_is_<const> where it is a boolean field, generate
 670         the result of the expression instead of the expression its self.
 671         (print_icache_body): Remove code that was looking for *_is_0 and
 672         then generating corresponding definitions.
 673
 674         * gen-icache.c (print_icache_struct): If there is no cache, do not
 675         output expressions in idecode.h file.
 676
 677         * gen-icache.c (print_icache_body): Output them here.
 678
 679         * ppc-opcode-complex: Clarify constant values for SPR==LR register
 680         expansion.
 681
 682         * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
 683
 684 Wed Jan 22 12:24:52 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 685
 686         * The code that put values in and extracted values from the cache
 687         was too compilicated.  The cache table did not allow values to be
 688         computed from cache entries.  #defines could only be used when a
 689         cache was present, remove the restriction.
 690
 691         * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH.  A
 692         scratch variable is defined when a cache entry is beinf
 693         filled. Change the definition of a COMPUTE variable to be defined
 694         when the cache entry is being used.
 695         * gen-icache.c: Update.
 696
 697         * ld-cache.h, ld-cache.c: Change field names so that their meaning
 698         is more obvious.  old_name->field_name, new_name->derived_name.
 699         * gen-icache.c: Update
 700
 701         * gen-icache.h, gen-icache.c (print_icache_body): Make the three
 702         different types of cache code - put into cache, extract from
 703         cache, no cache - an explicit argument to print_icache_body.
 704         * gen-icache.c (print_icache_extraction): Ditto.
 705
 706         * gen-semantics.c (print_c_semantic): Update use.
 707         * gen-idecode.c (print_jump_insn): Update use.
 708         * gen-icache.c (print_icache_function): Update use.
 709
 710         * igen.c (main): Change 'R' option so that it does not force the
 711         cache.
 712
 713         * configure.in (enable-sim-icache): Clarify description.  Make
 714         #define one of the defaults regardless of the cache.  Probably
 715         should revamp and add a separate option.
 716
 717 Tue Jan 21 13:26:10 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 718
 719         * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
 720         partition numbering.
 721         (pk_disklabel_create_instance): Partition 1..4 are valid - not

2124         * std-config.h: Change psim.c so that it isn't inlined (as this is
2125         no longer needed).
2126
2127         * psim.c (run_until_stop): Delete the old run_until_stop function
2128         instead calling the idecode_run and idecode_run_until_stop
2129         functions that gen-idecode.c is now creating.

2139
2140         * debug.c (TRACE, ITRACE, DTRACE): Have GCC instead of CPP
2141         eliminate trace statements.
2142
2143         * debug.c: Change trace format so that it is consistent
2144         (file:line-nr) with CC's error output.
2145

2163
2164         * gen-idecode.c (print_jump_until_stop_body): New function and
2165         idecode generation option.  Instead of generating and calling
2166         separate functions containing the semantic and icache code

2173
2174         * ppc-instructions: Eliminate any uses of labels and goto's.
2175         These result in duplicate declarations when a single flat function
2176         is being create.
2177
2178         * ppc-opcode-jump: New file.  Set of opcode rules useful when

2187         decode functions.
2188
2189         * configure.in (--enable-sim-icache): Accept an option list such
2190         as 1024,define.  Add a new choice to the list - semantic - which
2191         will cause igen to generate instruction decode functions that
2192         include the corresponding semantic code.

2198         generated files.  Such directives refer back to the source files
2199         used when generating the simulator code.
2200
2201         * Makefile.in (sim_line_nr): Pass to igen.

3175
3176         * device.c (external_to_device) : New function that provides a
3177         standard mapping between a devices internal representation (a
3178         pointer) and its external (or what is passed to a client)
3179         representation (a phandle).  Implement using the cap object
3180         attached to the root node.
3181
3182         * device.c (device_to_external) : Ditto
3183         * device.c (external_to_device_instance) : Ditto but for ihandle
3184         and device instance.
3185         * device.c (device_instance_to_external) : Ditto
3186
3187         * Makefile (device.o): Add dependency on cap.
3188
3189         * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3190         needing to translate between internal and external representations
3191         changed to use the external_to_device et.al. device operations.
3192         * emul_chirp.c (chirp_emul_*) : Ditto
3193
3194         * Makefile (emul_chirp.o): Remove dependency on cap

3202
3203         * emul_generic.c (emul_write_buffer): Use vm faulting byte
3204         read/write calls for buffer transfers.  This will cause a fault to
3205         occure if the transfer fails.  CHRP catches the fault while the
3206         others suffer the consequences.
3207         (emul_read_buffer): Ditto.
3208         (emul_write_word): Ditto.

3216         return from a client service call.
3217
3218         * emul_chirp.c (services): Add all OpenBoot services to table.
