   1 1998-11-19  Michael Meissner  <meissner@cygnus.com>
   2
   3         * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
   4         fractional type, so that quiet NaN's aren't treated like
   5         Infinities.
   6
   7 Mon Sep 28 09:42:45 1998  Drew Moseley  <dmoseley@cygnus.com>
   8
   9         * table.c (table_open): For cygwin hosts, we need to use the return value
  10         from the read routine as the number of bytes to process.  This apparently
  11         is due to text-mode vs binary-mode.  If the mounts are done text-mode,
  12         then the size returnedby fstat() may be different than the number of
  13         bytes "read" in text mode.

  38 Tue May 12 12:10:33 PDT 1998  James Ingham  <jingham@leda.cygnus.com>
  39
  40         * Makefile.in: The run target depended on a target psim$(EXEEXT),
  41         but there was no such target, only plain psim.  So I changed the
  42         run target to depend on psim.

  47         now defined in ../common/aclocal.m4, and the double definition causes
  48         problems with AC_SUBST of EXEEXT.
  49         * configure:  Regenerate.
  50
  51 Wed Apr 29 15:44:52 1998  Geoffrey Noer  <noer@cygnus.com>

 379         * gen-icache.c (print_icache_extraction): Add a reason parameter.
 380         Augment each extracted field with a comment citing the codes
 381         origin.  Should simplify tracking down incorrect cache
 382         extractions.
 383
 384 Tue Feb  4 17:44:51 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 385
 386         * gen-icache.c: Generalize code handling XXX_is_NNN so that it
 387         works for normal and boolean table entries.
 388
 389         * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
 390         valid.  Handle this just like *_{read,write}_register now handles
 391         it.
 392
 393 Mon Feb  3 17:18:16 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>

 404         max iterations exceeded.
 405
 406         * gen-idecode.c: Re-work the table lookup code so that it assumes
 407         that the entry is a leaf by default.  Simplify the boolean table
 408         entry code so that it involves a mask + test instead of shift +
 409         shift + mask + test.
 410
 411         * gen-idecode.c: Correct generated igen body so that it no drops
 412         or doubles clock interrupts.

 421         if common callback is present.
 422
 423 Wed Jan 29 12:32:41 1997  Michael Meissner  <meissner@tiktok.cygnus.com>
 424
 425         * configure.in (sim_callback): If the gdb is post 4.16, configure
 426         callback support from the common directory.
 427         * configure: Regenerate.
 428
 429         * Makefile.in (BUILT_SRC_WO_CONFIG): Add targ-vals.{h,def} and
 430         targ-map.c.
 431         (GDB_OBJ): Add callback support configured in.
 432         (gentmap,targ-vals.def): Build from common directory.
 433         (targ-vals.h,targ-map.c): Build by running gentmap.

 437
 438 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 439
 440         * igen wasn't aborting if the opcode table contained no valid
 441         fields.
 442
 443         * misc.c (name2i): Possibly abort if an invalid name is
 444         encountered.
 445         * ld-decode.c: Abort if the table type isn't found.
 446
 447 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 448
 449         * When performance monitoring is disabled, it is still possible to
 450         determine the simulation speed by looking at the number of elapsed
 451         ticks recorded by the event queue.
 452
 453         * psim.c (psim_write_register, psim_read_register): Force the cpu
 454         to zero when it is either of `-1' or `nr_cpus'.  In both cases the
 455         next cpu would be zero any way.
 456
 457         * mon.c (mon_print_info): If possible, print the system cycle
 458         performance.  This is an indication of the number of instructions
 459         per second.
 460
 461 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 462
 463         * The code to allow an event queue to be updated during a signal
 464         was missing.  For main.c, a cntrl-c simulation termination wasn't
 465         handled cleanly.
 466
 467         * The simulation would not correctly restart if an event requested
 468         that the simulation be halted.
 469
 470         * psim.c (psim_options): Add hack to -i option to optionally
 471         include a level vis -i2.
 472         (psim_usage): Document.
 473
 474         * main.c (cntrl_c, cntrl_c_simulation): New functions.  When a
 475         cntrl-c occures schedule an event to halt the simulation.
 476         (main): Catch CNTRL-C signals with the function cntrl_c.
 477
 478         * events.c (event_queue_process): Mask interrupts while
 479         manipulating the async event queue.
 480         (event_queue_init): Ditto.
 481         (event_queue_schedule_after_signal): Ditto.
 482
 483         * events.c (event_queue_process): Mark the event queue as being in
 484         the processing state when processing has started.  Adjust code
 485         so that it is tolerant of halts.
 486         (event_queue_init): Start the event queue out with processing
 487         false.
 488         (event_queue_tick): Check that processing isn't still being
 489         performed.
 490
 491         * gen-idecode.c (print_run_until_stop_body): Call
 492         event_queue_process_events to clear possibly pending events before
 493         starting a simulation run.  Re-arange main loop so that simulator
 494         is correctly restarted when an event halts the simulation.
 495
 496         * psim.c (psim_halt): Handle an event halting the simulation.
 497         * psim.c (psim_init): Adjust initial cpu - == -1 - to match
 498         reworked idecode.
 499
 500 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 501
 502         * ppc-opcode-complex: Correct typo - was expanding ORA instead of
 503         RA.  Based on instruction frequency stats, expand additional
 504         instructions.
 505         * ppc-instructions: Change all `RA == 0' to RA_is_0.
 506
 507         * ppc-opcode-stupid: Move all but the basic table in -complex into
 508         here.  Update to new format.
 509
 510         * Makefile.in (tmp-defines): New target. Force defines.h to always
 511         be built.  Hence get ppc-opcode-goto to build.
 512
 513 Tue Jan 28 13:00:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 514
 515         * hw_com.c (hw_com_instance_read, hw_com_instance_write):
 516         Implement.
 517
 518 Thu Jan 23 09:07:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 519
 520         * hw_trace.c (hw_trace_init_data): Delete.  The trace options need
 521         to be initialized independant of the rest of the simulation
 522         initalization.  Otherwize a trace option explictly set from gdb
 523         could be overridden by hw_trace.
 524
 525         * psim.c (psim_options): Clarify reason why the trace ioctl occures.
 526
 527         * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
 528         debug.c.  It could be much simpler.
 529
 530 Thu Jan 23 09:07:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 531
 532         * Some devices support removable media.  Add hooks to the disk
 533         device so that it supports this.
 534
 535         * device.c (device_add_string_array_property,
 536         device_find_string_array_property): New functions, manipulate
 537         properties containing an array of strings.
 538         (device_find_string_property): Allow a string array.
 539         (device_init_static_properties): Update.
 540         (device_init_runtime_properties): Update.
 541
 542         * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
 543         media.  If no file image is specified, use the next one in the
 544         image property list.
 545         (hw_disk_init_address): Change the file property so that it is a
 546         string array - use the first entry for the initial file image.
 547
 548         * tree.c (print_string_aray_property): New function - print a
 549         string array.
 550         (print_properties): Adjust.
 551         (print_string): Write a string, handling double quotes.
 552
 553         * device.h: Define an ioctl to `change-media' with an optional new
 554         media image.
 555
 556         * hw_disk.c: Allow floppy disk devices to be specified.
 557
 558         * psim.c (psim_command): New function, parse more complex psim
 559         commands such as "change-media" and "trace".
 560         * sim_calls.c (sim_do_command): Use.
 561
 562 Wed Jan 22 09:38:33 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 563
 564         * For expressions like (RA == 0) that are entered in to the cache
 565         as RA_is_0. If possible generate the result of the expression so
 566         that the compiler gets a better chance of eliminating dead
 567         branches.
 568
 569         * gen-icache.c (print_icache_extraction): For a cache entry of
 570         the form <name>_is_<const> where it is a boolean field, generate
 571         the result of the expression instead of the expression its self.
 572         (print_icache_body): Remove code that was looking for *_is_0 and
 573         then generating corresponding definitions.
 574
 575         * gen-icache.c (print_icache_struct): If there is no cache, do not
 576         output expressions in idecode.h file.
 577
 578         * gen-icache.c (print_icache_body): Output them here.
 579

 583         * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
 584
 585 Wed Jan 22 12:24:52 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 586
 587         * The code that put values in and extracted values from the cache
 588         was too compilicated.  The cache table did not allow values to be
 589         computed from cache entries.  #defines could only be used when a
 590         cache was present, remove the restriction.
 591
 592         * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH.  A
 593         scratch variable is defined when a cache entry is beinf
 594         filled. Change the definition of a COMPUTE variable to be defined
 595         when the cache entry is being used.
 596         * gen-icache.c: Update.
 597
 598         * ld-cache.h, ld-cache.c: Change field names so that their meaning
 599         is more obvious.  old_name->field_name, new_name->derived_name.

 601
 602         * gen-icache.h, gen-icache.c (print_icache_body): Make the three
 603         different types of cache code - put into cache, extract from
 604         cache, no cache - an explicit argument to print_icache_body.
 605         * gen-icache.c (print_icache_extraction): Ditto.
 606
 607         * gen-semantics.c (print_c_semantic): Update use.
 608         * gen-idecode.c (print_jump_insn): Update use.
 609         * gen-icache.c (print_icache_function): Update use.
 610
 611         * igen.c (main): Change 'R' option so that it does not force the
 612         cache.
 613
 614         * configure.in (enable-sim-icache): Clarify description.  Make
 615         #define one of the defaults regardless of the cache.  Probably
 616         should revamp and add a separate option.
 617
 618 Tue Jan 21 13:26:10 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 619
 620         * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
 621         partition numbering.
 622         (pk_disklabel_create_instance): Partition 1..4 are valid - not

 625         (pk_disklabel_create_instance): Start expanding so that active
 626         partition selection is supported.
 627
 628 Mon Jan 20 11:20:15 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 629
 630         * The cap object was retaining a reference to the instance of a
 631         device after it was deleted. Instead add and remove cap's from the
 632         cap db as they are created and deleted.  This ensuring that a
 633         capibility is only used during the lifetime of the corresponding
 634         object.
 635
 636         * cap.h, cap.c: Correct cap type - was signed32 should be
 637         signed_cell.
 638
 639         * cap.c (cap_add, cap_remove): New methods for cap object that
 640         allow the explicit addition and removal of internal objects that
 641         the cap knows about.
 642
 643         * cap.c (cap_init): Rewrite.  Verify that the only objects
 644         remaining in the cap data base are those that were entered first.
 645         Thse objects will be the permenant ones.
 646         * device.c (device_init_address): Remember to initialize the cap
 647         database.
 648
 649         * device.c (device_create_instance_from): Explicitly add device
 650         instances to the cap database.  Simplify create code.
 651         (device_instance_delete): Explicitly remove device instances from
 652         the cap database.
 653
 654         * device.c (device_create_from): Explicitly add a device to the
 655         cap data base.
 656
 657         * device.c (device_create_from): Always set the cap members.

 668
 669         * The memory "claim" and "release" methods take an address and
 670         size as arguments.  These may be multi cell values. Initially fix
 671         the memory code so that they check/detect this.  Leave the
 672         adjustment of any clients to later.
 673
 674         * hw_memory.c (hw_memory_instance_claim,
 675         hw_memory_instance_release): Handle multi-cell memory devices.
 676
 677         * hw_memory.c (hw_memory_instance_claim): Be tolerant towards the
 678         release of memory regions that were not claimed.
 679

 681
 682         * device.h, device.c (device_instance_call_method): Correct return

 696
 697         * Makefile.in (LIB_INLINE_SRC): Remove emul_* from list of files
 698         that are inlined.  These modules are called via a table and are
 699         not made inline.
 700
 701         * hw_init.c (update_for_binary_section): Fix failure to allocate
 702         memory used by the binary in real-mode executions. If "claim"
 703         property is present, allocate memory from the "/chosen/memory"

 705
 706         * emul_chirp.c (emul_chirp_create): Specify that memory should be
 707         claimed when loading a real image.
 708
 709         * hw_memory.c (hw_memory_instance_claim): Don't page align memory
 710         allocations.

 716
 717         * vm.h (vm_data_map_read_buffer, vm_data_map_write_buffer): Add
 718         optional PROCESSOR & CIA args so that this routine also abort an
 719         access.

 721         * vm_n.h (vm_data_map_read_N, vm_data_map_write_N): For a
 722         miss-aligned access when a transfer fails abort.
 723
 724         * emul_bugapi.c (emul_bugapi_do_write): Use emul_read_buffer

1835
1836         * std-config.h (CURRENT_STDIO, current_stdio): New macro. Set up
1837         stdio configuration so that it works in the same way as the rest

1860
1861         * ppc-cache-rules (cache): Change RS and RB to cache instead of

1894
1895         * std-config.h (SEMANTICS_INLINE): By default, mask out the
1896         inlining of semantic functions from DEFAULT_INLINE.  Almost all
1897         configurations call the semantic code via a pointer so there is

1899
1900         * std-config.h (ICACHE_INLINE): Ditto.
1901
1902 Thu Jul 25 20:07:30 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>

1929
1930         * gen-idecode.c (print_idecode_switch_illegal): Include a break
1931         when generating illegal instructions.  This was commented out
1932         which is a hangover from looking a at switch statements generated
1933         using indirect jumps.
1934
1935 Tue Jul 23 20:57:01 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
1936

1942
1943         * gen-support.c (gen_support_h): Add optional include to created
1944         support.h so that, like cpu, it is optionally inlined for all

1947         same as cpu.[hc].
1948
1949         * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
1950         name for a lable and then branch to it.
1951
1952         * ppc-instructions (convert_to_integer, Floating Round to
1953         Single-Precision, Floating Convert from Integer Doubleword): Use

1955
1956 Wed Jul 24 14:02:42 1996  Andrew Cagney  <cagney@sawnoff.highland.com.au>
1957
1958         * gen-idecode.c (print_run_until_stop_body): Too many rparen in
1959         generated code.

1967         * configure: rebuild.
1968
1969 Mon Jul 22 23:25:08 1996  Andrew Cagney  <cagney@highland.com.au>
1970
1971         * configure.in (--enable-sim-hardware, --enable-sim-packages): New
1972         configuration options.  Let the user specify the packages or
1973         hardware devices that are to be included in the build.  Makes it
1974         possible for user packages to be specified.
1975
1976         * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
1977         hardware instead of checking it using ls.  configure.in should
1978         have taken care of any problems.
1979         (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
1980
1981 Mon Jul 22 22:38:59 1996  Andrew Cagney  <cagney@highland.com.au>
1982
1983         * psim.c (psim_options): Enter the argument to the memory size
1984         option directly into the device tree.  Was using atol() which is
1985         dangerously non portable.
1986
1987 Mon Jul 22 22:17:08 1996  Andrew Cagney  <cagney@highland.com.au>
1988
1989         * configure.in (icache): Extend icache flag to include an insn

2007
2008         * emul_generic.c (emul_add_tree_options): Was incorrectly setting

2017         not my_index.
2018
2019 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2020
2021         * gen-idecode.c: Output the complete run_until_stop function
2022         instead of just the code to handle a single instruction issue.
2023         * : Have the generated idecode.c include inline.c (instead of psim.c).
2024
2025         * std-config.h: Change psim.c so that it isn't inlined (as this is
2026         no longer needed).
2027
2028         * psim.c (run_until_stop): Delete the old run_until_stop function
2029         instead calling the idecode_run and idecode_run_until_stop
2030         functions that gen-idecode.c is now creating.
2031
2032 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2033

2040
2041         * debug.c (TRACE, ITRACE, DTRACE): Have GCC instead of CPP
2042         eliminate trace statements.
2043

2057         corresponding call to ITRACE so that it still matches.
2058
2059         * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
2060         of ITRACE.  The CPP line directives would have previously set the
2061         line-nr and file name so ITRACE isn't needed.
2062
2063 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2064
2065         * gen-idecode.c (print_jump_until_stop_body): New function and
2066         idecode generation option.  Instead of generating and calling
2067         separate functions containing the semantic and icache code
2068         generate a single monolythic function and use goto's (and GCC's
2069         indirect jump) to move between code blocks.

2077         is being create.
2078
2079         * ppc-opcode-jump: New file.  Set of opcode rules useful when
2080         testing jumping idecodes.

2083
2084         * gen-idecode.c: Optionally include the semantic code for an
2085         instruction in the function that is doing the decoding.
2086
2087         * igen.c: Add option (-C) to generate semantics in the instruction
2088         decode functions.
2089
2090         * configure.in (--enable-sim-icache): Accept an option list such
2091         as 1024,define.  Add a new choice to the list - semantic - which
2092         will cause igen to generate instruction decode functions that
2093         include the corresponding semantic code.
2094
2095 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2096

2098         Enable/disable the inclusion of CPP line directives in the
2099         generated files.  Such directives refer back to the source files
2100         used when generating the simulator code.
2101
2102         * Makefile.in (sim_line_nr): Pass to igen.
2103
2104 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2105
2106         * igen.c (main): Revamp the options so that more letters are
2107         available.
2108
2109         * configure.in: Adjust to match igen's revamped options
2110
2111 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2112
2113         * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
2114         that they use the same technique as igen (ie a dummy targets
2115         tmp-pk and tmp-hw are created).
2116
2117 Mon Jun 24 22:28:00 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
