  36
  37 1999-04-02  Keith Seitz  <keiths@cygnus.com>
  38
  39         * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
  40         the frequency at which the poll_quit callback is called.
  41         (poll_quit_count): New global.
  42         (sim_io_poll_quit): Only call the poll_quit callback
  43         after the specified POLL_QUIT_INTERVAL.
  44
  45 1999-02-22  Jim Lemke  <jlemke@cygnus.com>
  46
  47         * dc-complex: Force expansion on all bits of field BO.

  54
  55 1999-02-01  Jim Blandy  <jimb@zwingli.cygnus.com>
  56
  57         Make the simulator compatible with the MPC750.  It would be nicer
  58         to make this a real multi-sim, but that's more work than we have
  59         time for.
  60         * emul_generic.c (emul_add_tree_options): Only require strict
  61         alignment if it was explicitly requested at configuration time.
  62         Don't make it the default for little-endian machines.
  63         * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
  64         MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
  65         THRM2, THRM3): Plop in the MPC750 SPR registers.
  66         (DABR): This is weird.  This was HID5, but the PPC spec says this
  67         should be DABR; why did some random processor use it for something
  68         else?  The HID5 entry dates back to the original checkin of the
  69         simulator code in 1995, so remove it.
  70         * sim_calls.c (register_names): Delete this; since the user can
  71         now change GDB's list of register names dynamically, we can't
  72         pretend there's a static mapping here.
  73         (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
  74         function to get the register name.  That ought to be accurate.
  75         However, we're changing a compile-time dependency (using the
  76         REGISTER_NAMES macro) into a link- and run-time dependency
  77         (calling REGISTER_NAME, which happens to be a function call on the
  78         PPC).
  79
  80 1999-01-22  Jim Lemke <jlemke@cygnus.com>
  81
  82         * igen.c(gen_semantics_[ch]): setup/use of new option
  83         (-o mpc860c0[=n]).
  84         interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
  85         ppc-instructions(the four branch insn groups): detect problematic br's.
  86         psim.c(is_num - added, psim_options): Parse and init new option.
  87         These changes are currently under #ifdef WITH_OPTION_MPC860C0.
  88
  89 1998-12-01  Ken Raeburn  <raeburn@cygnus.com>
  90
  91         * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.
  92
  93 Fri Nov 20 12:17:28 1998  Andrew Cagney  <cagney@b1.cygnus.com>
  94
  95         * main.c (sim_io_poll_quit): Stub function.
  96
  97         * events.c (SIM_EVENTS_POLL_RATE): Define.
  98         (sim_events_poll): Copy function from common/sim-events.c.
  99         (event_queue_init): Copy scheduling of sim_events_poll from same.
 100
 101         * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
 102         poll the external environment.
 103
 104 1998-11-19  Michael Meissner  <meissner@cygnus.com>
 105
 106         * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
 107         fractional type, so that quiet NaN's aren't treated like
 108         Infinities.
 109
 110 Mon Sep 28 09:42:45 1998  Drew Moseley  <dmoseley@cygnus.com>
 111
 112         * table.c (table_open): For cygwin hosts, we need to use the
 113         return value from the read routine as the number of bytes to
 114         process.  This apparently is due to text-mode vs binary-mode.  If
 115         the mounts are done text-mode, then the size returnedby fstat()
 116         may be different than the number of bytes "read" in text mode.
 117
 118 Sun Oct  4 00:50:47 1998  Felix Lee  <flee@cygnus.com>
 119
 120         * emul_netbsd.c (do_open): fix order-of-evaluation problem.

 128
 129 Mon Jun 29 10:57:36 1998  Michael Snyder  <msnyder@cleaver.cygnus.com>
 130
 131         * sim_calls.c (sim_fetch_register, sim_store_register):
 132         return zero when nothing to do.
 133
 134 1998-06-26  Michael Meissner  <meissner@cygnus.com>
 135
 136         * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
 137         * configure: Regenerate.
 138         * emul_{netbsd,unix}.c (toplevel): No longer try to include
 139         sys/mount.h. It conflicts on Linux when gnu libc2 is used.
 140
 141 Tue May 12 12:10:33 PDT 1998  James Ingham  <jingham@leda.cygnus.com>
 142
 143         * Makefile.in: The run target depended on a target psim$(EXEEXT),
 144         but there was no such target, only plain psim.  So I changed the
 145         run target to depend on psim.
 146
 147 Sat May  2 01:10:12 1998  Stu Grossman  <grossman@babylon-5.cygnus.com>
 148
 149         * aclocal.m4:  Remove defs of AM_EXEEXT and AM_CYGWIN32.  These are
 150         now defined in ../common/aclocal.m4, and the double definition causes
 151         problems with AC_SUBST of EXEEXT.
 152         * configure:  Regenerate.
 153
 154 Wed Apr 29 15:44:52 1998  Geoffrey Noer  <noer@cygnus.com>

 394
 395         * Makefile.in (targ-vals.def): Re-do rule so that it works with
 396         FreeBSD's make.  Didn't like $<.
 397

 420
 421 Wed Feb 12 19:33:45 1997  Andrew Cagney  <cagney@phydeaux.cygnus.com>
 422
 423         * Many of the ppc-opcode-* files are identical baring the type of
 424         lookup table.  Instead of having multiple tables, igen can do this
 425         via an additional option.
 426
 427         * ld-decode.h, ld-decode.c (force_decode_gen_type): New function,
 428         allow the type of generated table specified in the decode file to
 429         be overridden.
 430
 431         * ld-decode.c (load_decode_table): Allow the table type to be
 432         overridden.

 465         found in the device tree.
 466
 467 Wed Feb  5 10:56:27 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 468
 469         * Property create/initialization still wasn't correctly ordered.
 470         Should be delaying everything related to ihandle creation until
 471         after the rest of the tree has been established.
 472
 473         * device.c (device_find_ihandle_runtime_property): Update.

 483         Augment each extracted field with a comment citing the codes
 484         origin.  Should simplify tracking down incorrect cache
 485         extractions.
 486
 487 Tue Feb  4 17:44:51 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 488
 489         * gen-icache.c: Generalize code handling XXX_is_NNN so that it
 490         works for normal and boolean table entries.
 491
 492         * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
 493         valid.  Handle this just like *_{read,write}_register now handles
 494         it.
 495
 496 Mon Feb  3 17:18:16 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>

 503         * psim.c (psim_options): Add new option -c for max-iterations or
 504         count.
 505         (psim_usage): Document.
 506         (psim_max_iterations_exceeded): New function, abort simulation if
 507         max iterations exceeded.
 508
 509         * gen-idecode.c: Re-work the table lookup code so that it assumes
 510         that the entry is a leaf by default.  Simplify the boolean table
 511         entry code so that it involves a mask + test instead of shift +
 512         shift + mask + test.
 513
 514         * gen-idecode.c: Correct generated igen body so that it no drops
 515         or doubles clock interrupts.
 516
 517
 518 Thu Jan 30 11:23:20 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 519

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

 541 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 542
 543         * igen wasn't aborting if the opcode table contained no valid
 544         fields.
 545
 546         * misc.c (name2i): Possibly abort if an invalid name is
 547         encountered.
 548         * ld-decode.c: Abort if the table type isn't found.
 549
 550 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 551
 552         * When performance monitoring is disabled, it is still possible to
 553         determine the simulation speed by looking at the number of elapsed
 554         ticks recorded by the event queue.
 555
 556         * psim.c (psim_write_register, psim_read_register): Force the cpu
 557         to zero when it is either of `-1' or `nr_cpus'.  In both cases the
 558         next cpu would be zero any way.
 559
 560         * mon.c (mon_print_info): If possible, print the system cycle
 561         performance.  This is an indication of the number of instructions
 562         per second.
 563
 564 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 565
 566         * The code to allow an event queue to be updated during a signal
 567         was missing.  For main.c, a cntrl-c simulation termination wasn't
 568         handled cleanly.
 569
 570         * The simulation would not correctly restart if an event requested
 571         that the simulation be halted.
 572
 573         * psim.c (psim_options): Add hack to -i option to optionally
 574         include a level vis -i2.
 575         (psim_usage): Document.
 576
 577         * main.c (cntrl_c, cntrl_c_simulation): New functions.  When a
 578         cntrl-c occures schedule an event to halt the simulation.
 579         (main): Catch CNTRL-C signals with the function cntrl_c.
 580
 581         * events.c (event_queue_process): Mask interrupts while
 582         manipulating the async event queue.
 583         (event_queue_init): Ditto.
 584         (event_queue_schedule_after_signal): Ditto.
 585
 586         * events.c (event_queue_process): Mark the event queue as being in
 587         the processing state when processing has started.  Adjust code
 588         so that it is tolerant of halts.
 589         (event_queue_init): Start the event queue out with processing
 590         false.
 591         (event_queue_tick): Check that processing isn't still being
 592         performed.
 593
 594         * gen-idecode.c (print_run_until_stop_body): Call
 595         event_queue_process_events to clear possibly pending events before
 596         starting a simulation run.  Re-arange main loop so that simulator
 597         is correctly restarted when an event halts the simulation.
 598
 599         * psim.c (psim_halt): Handle an event halting the simulation.
 600         * psim.c (psim_init): Adjust initial cpu - == -1 - to match
 601         reworked idecode.
 602
 603 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 604
 605         * ppc-opcode-complex: Correct typo - was expanding ORA instead of
 606         RA.  Based on instruction frequency stats, expand additional
 607         instructions.
 608         * ppc-instructions: Change all `RA == 0' to RA_is_0.
 609
 610         * ppc-opcode-stupid: Move all but the basic table in -complex into
 611         here.  Update to new format.
 612
 613         * Makefile.in (tmp-defines): New target. Force defines.h to always
 614         be built.  Hence get ppc-opcode-goto to build.
 615
 616 Tue Jan 28 13:00:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 617
 618         * hw_com.c (hw_com_instance_read, hw_com_instance_write):
 619         Implement.
 620
 621 Thu Jan 23 09:07:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 622
 623         * hw_trace.c (hw_trace_init_data): Delete.  The trace options need
 624         to be initialized independant of the rest of the simulation
 625         initalization.  Otherwize a trace option explictly set from gdb
 626         could be overridden by hw_trace.
 627
 628         * psim.c (psim_options): Clarify reason why the trace ioctl occures.
 629
 630         * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
 631         debug.c.  It could be much simpler.
 632
 633 Thu Jan 23 09:07:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 634
 635         * Some devices support removable media.  Add hooks to the disk
 636         device so that it supports this.
 637
 638         * device.c (device_add_string_array_property,
 639         device_find_string_array_property): New functions, manipulate
 640         properties containing an array of strings.
 641         (device_find_string_property): Allow a string array.
 642         (device_init_static_properties): Update.
 643         (device_init_runtime_properties): Update.
 644
 645         * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
 646         media.  If no file image is specified, use the next one in the
 647         image property list.
 648         (hw_disk_init_address): Change the file property so that it is a
 649         string array - use the first entry for the initial file image.
 650
 651         * tree.c (print_string_aray_property): New function - print a
 652         string array.
 653         (print_properties): Adjust.
 654         (print_string): Write a string, handling double quotes.
 655
 656         * device.h: Define an ioctl to `change-media' with an optional new
 657         media image.
 658
 659         * hw_disk.c: Allow floppy disk devices to be specified.
 660
 661         * psim.c (psim_command): New function, parse more complex psim
 662         commands such as "change-media" and "trace".
 663         * sim_calls.c (sim_do_command): Use.
 664
 665 Wed Jan 22 09:38:33 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 666
 667         * For expressions like (RA == 0) that are entered in to the cache
 668         as RA_is_0. If possible generate the result of the expression so
 669         that the compiler gets a better chance of eliminating dead
 670         branches.
 671
 672         * gen-icache.c (print_icache_extraction): For a cache entry of
 673         the form <name>_is_<const> where it is a boolean field, generate
 674         the result of the expression instead of the expression its self.
 675         (print_icache_body): Remove code that was looking for *_is_0 and
 676         then generating corresponding definitions.
 677
 678         * gen-icache.c (print_icache_struct): If there is no cache, do not
 679         output expressions in idecode.h file.
 680
 681         * gen-icache.c (print_icache_body): Output them here.
 682
 683         * ppc-opcode-complex: Clarify constant values for SPR==LR register
 684         expansion.
 685
 686         * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
 687
 688 Wed Jan 22 12:24:52 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 689
 690         * The code that put values in and extracted values from the cache
 691         was too compilicated.  The cache table did not allow values to be
 692         computed from cache entries.  #defines could only be used when a
 693         cache was present, remove the restriction.
 694
 695         * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH.  A
 696         scratch variable is defined when a cache entry is beinf
 697         filled. Change the definition of a COMPUTE variable to be defined
 698         when the cache entry is being used.
 699         * gen-icache.c: Update.
 700
 701         * ld-cache.h, ld-cache.c: Change field names so that their meaning
 702         is more obvious.  old_name->field_name, new_name->derived_name.
 703         * gen-icache.c: Update
 704
 705         * gen-icache.h, gen-icache.c (print_icache_body): Make the three
 706         different types of cache code - put into cache, extract from
 707         cache, no cache - an explicit argument to print_icache_body.
 708         * gen-icache.c (print_icache_extraction): Ditto.
 709
 710         * gen-semantics.c (print_c_semantic): Update use.
 711         * gen-idecode.c (print_jump_insn): Update use.
 712         * gen-icache.c (print_icache_function): Update use.
 713
 714         * igen.c (main): Change 'R' option so that it does not force the
 715         cache.
 716
 717         * configure.in (enable-sim-icache): Clarify description.  Make
 718         #define one of the defaults regardless of the cache.  Probably
 719         should revamp and add a separate option.
 720
 721 Tue Jan 21 13:26:10 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 722
 723         * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

2128         * std-config.h: Change psim.c so that it isn't inlined (as this is
2129         no longer needed).
2130
2131         * psim.c (run_until_stop): Delete the old run_until_stop function
2132         instead calling the idecode_run and idecode_run_until_stop
2133         functions that gen-idecode.c is now creating.

2141
2142 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2143
2144         * debug.c (TRACE, ITRACE, DTRACE): Have GCC instead of CPP
2145         eliminate trace statements.
2146
2147         * debug.c: Change trace format so that it is consistent
2148         (file:line-nr) with CC's error output.
2149

2151         source line number to the instruction's informational entry.
2152
2153         * debug.c (ITRACE): Use the itable (and my_index) to get the

2160         corresponding call to ITRACE so that it still matches.
2161
2162         * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
2163         of ITRACE.  The CPP line directives would have previously set the

2167
2168         * gen-idecode.c (print_jump_until_stop_body): New function and
2169         idecode generation option.  Instead of generating and calling
2170         separate functions containing the semantic and icache code

2175
2176         * configure.in: New option --enable-sim-jump (default disabled)
2177
2178         * ppc-instructions: Eliminate any uses of labels and goto's.
2179         These result in duplicate declarations when a single flat function
2180         is being create.
2181
2182         * ppc-opcode-jump: New file.  Set of opcode rules useful when

2191         decode functions.
2192
2193         * configure.in (--enable-sim-icache): Accept an option list such
2194         as 1024,define.  Add a new choice to the list - semantic - which
2195         will cause igen to generate instruction decode functions that
2196         include the corresponding semantic code.

2202         generated files.  Such directives refer back to the source files
2203         used when generating the simulator code.
2204
2205         * Makefile.in (sim_line_nr): Pass to igen.

3179
3180         * device.c (external_to_device) : New function that provides a
3181         standard mapping between a devices internal representation (a
3182         pointer) and its external (or what is passed to a client)
3183         representation (a phandle).  Implement using the cap object
3184         attached to the root node.
3185
3186         * device.c (device_to_external) : Ditto
3187         * device.c (external_to_device_instance) : Ditto but for ihandle
3188         and device instance.
3189         * device.c (device_instance_to_external) : Ditto
3190
3191         * Makefile (device.o): Add dependency on cap.
3192
3193         * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3194         needing to translate between internal and external representations
3195         changed to use the external_to_device et.al. device operations.
3196         * emul_chirp.c (chirp_emul_*) : Ditto
3197
3198         * Makefile (emul_chirp.o): Remove dependency on cap

3206
3207         * emul_generic.c (emul_write_buffer): Use vm faulting byte
3208         read/write calls for buffer transfers.  This will cause a fault to
3209         occure if the transfer fails.  CHRP catches the fault while the
3210         others suffer the consequences.
3211         (emul_read_buffer): Ditto.
3212         (emul_write_word): Ditto.

3220         return from a client service call.
3221
3222         * emul_chirp.c (services): Add all OpenBoot services to table.
