   2
   3         * hw_trace.c (hw_trace_init_data): Delete.  The trace options need
   4         to be initialized independant of the rest of the simulation
   5         initalization.  Otherwize a trace option explictly set from gdb
   6         could be overridden by hw_trace.
   7
   8         * psim.c (psim_options): Clarify reason why the trace ioctl occures.
   9
  10         * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
  11         debug.c.  It could be much simpler.
  12
  13 Thu Jan 23 09:07:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
  14
  15         * Some devices support removable media.  Add hooks to the disk
  16         device so that it supports this.
  17
  18         * device.c (device_add_string_array_property,
  19         device_find_string_array_property): New functions, manipulate

  25         * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
  26         media.  If no file image is specified, use the next one in the
  27         image property list.
  28         (hw_disk_init_address): Change the file property so that it is a
  29         string array - use the first entry for the initial file image.
  30
  31         * tree.c (print_string_aray_property): New function - print a
  32         string array.
  33         (print_properties): Adjust.
  34         (print_string): Write a string, handling double quotes.

  37         media image.
  38
  39         * hw_disk.c: Allow floppy disk devices to be specified.
  40
  41         * psim.c (psim_command): New function, parse more complex psim

  44
  45 Wed Jan 22 09:38:33 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
  46
  47         * For expressions like (RA == 0) that are entered in to the cache
  48         as RA_is_0. If possible generate the result of the expression so
  49         that the compiler gets a better chance of eliminating dead
  50         branches.
  51
  52         * gen-icache.c (print_icache_extraction): For a cache entry of
  53         the form <name>_is_<const> where it is a boolean field, generate
  54         the result of the expression instead of the expression its self.
  55         (print_icache_body): Remove code that was looking for *_is_0 and
  56         then generating corresponding definitions.
  57
  58         * gen-icache.c (print_icache_struct): If there is no cache, do not

  67
  68 Wed Jan 22 12:24:52 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
  69
  70         * The code that put values in and extracted values from the cache
  71         was too compilicated.  The cache table did not allow values to be
  72         computed from cache entries.  #defines could only be used when a
  73         cache was present, remove the restriction.
  74
  75         * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH.  A
  76         scratch variable is defined when a cache entry is beinf
  77         filled. Change the definition of a COMPUTE variable to be defined
  78         when the cache entry is being used.
  79         * gen-icache.c: Update.
  80
  81         * ld-cache.h, ld-cache.c: Change field names so that their meaning

  84
  85         * gen-icache.h, gen-icache.c (print_icache_body): Make the three
  86         different types of cache code - put into cache, extract from
  87         cache, no cache - an explicit argument to print_icache_body.
  88         * gen-icache.c (print_icache_extraction): Ditto.
  89
  90         * gen-semantics.c (print_c_semantic): Update use.
  91         * gen-idecode.c (print_jump_insn): Update use.
  92         * gen-icache.c (print_icache_function): Update use.
  93
  94         * igen.c (main): Change 'R' option so that it does not force the
  95         cache.
  96
  97         * configure.in (enable-sim-icache): Clarify description.  Make
  98         #define one of the defaults regardless of the cache.  Probably
  99         should revamp and add a separate option.
 100
 101 Tue Jan 21 13:26:10 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 102

 108         (pk_disklabel_create_instance): Start expanding so that active
 109         partition selection is supported.
 110
 111 Mon Jan 20 11:20:15 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 112
 113         * The cap object was retaining a reference to the instance of a
 114         device after it was deleted. Instead add and remove cap's from the
 115         cap db as they are created and deleted.  This ensuring that a
 116         capibility is only used during the lifetime of the corresponding
 117         object.
 118
 119         * cap.h, cap.c: Correct cap type - was signed32 should be

 125
 126         * cap.c (cap_init): Rewrite.  Verify that the only objects
 127         remaining in the cap data base are those that were entered first.
 128         Thse objects will be the permenant ones.

 130         database.
 131
 132         * device.c (device_create_instance_from): Explicitly add device
 133         instances to the cap database.  Simplify create code.

 153         size as arguments.  These may be multi cell values. Initially fix
 154         the memory code so that they check/detect this.  Leave the
 155         adjustment of any clients to later.
 156
 157         * hw_memory.c (hw_memory_instance_claim,

1451
1452 Mon Jul 22 23:25:08 1996  Andrew Cagney  <cagney@highland.com.au>
1453
1454         * configure.in (--enable-sim-hardware, --enable-sim-packages): New
1455         configuration options.  Let the user specify the packages or
1456         hardware devices that are to be included in the build.  Makes it
1457         possible for user packages to be specified.
1458
1459         * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
1460         hardware instead of checking it using ls.  configure.in should
1461         have taken care of any problems.
1462         (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
1463
1464 Mon Jul 22 22:38:59 1996  Andrew Cagney  <cagney@highland.com.au>
1465
1466         * psim.c (psim_options): Enter the argument to the memory size
1467         option directly into the device tree.  Was using atol() which is
1468         dangerously non portable.

1470 Mon Jul 22 22:17:08 1996  Andrew Cagney  <cagney@highland.com.au>
1471
1472         * configure.in (icache): Extend icache flag to include an insn
1473         option.  If specifyed the insn - aka instruction - is included in

1476
1477         * igen.c (main), igen.h: Add option -S - inSn - for specifying

1490
1491         * emul_generic.c (emul_add_tree_options): Was incorrectly setting

1500         not my_index.
1501
1502 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
1503
1504         * gen-idecode.c: Output the complete run_until_stop function
1505         instead of just the code to handle a single instruction issue.
1506         * : Have the generated idecode.c include inline.c (instead of psim.c).
1507
1508         * std-config.h: Change psim.c so that it isn't inlined (as this is
1509         no longer needed).
1510
1511         * psim.c (run_until_stop): Delete the old run_until_stop function
1512         instead calling the idecode_run and idecode_run_until_stop
1513         functions that gen-idecode.c is now creating.
1514
1515 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
1516

1523
1524         * debug.c (TRACE, ITRACE, DTRACE): Have GCC instead of CPP
1525         eliminate trace statements.
1526
1527         * debug.c: Change trace format so that it is consistent

1531         source line number to the instruction's informational entry.
1532
1533         * debug.c (ITRACE): Use the itable (and my_index) to get the
1534         current instructions name and source line number.
1535
1536         * gen-semantics.c, gen-icache.c: Adjust generated ITRACE calls to

1540         corresponding call to ITRACE so that it still matches.
1541
1542         * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
1543         of ITRACE.  The CPP line directives would have previously set the
1544         line-nr and file name so ITRACE isn't needed.
1545
1546 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
1547
1548         * gen-idecode.c (print_jump_until_stop_body): New function and
1549         idecode generation option.  Instead of generating and calling
1550         separate functions containing the semantic and icache code
1551         generate a single monolythic function and use goto's (and GCC's
1552         indirect jump) to move between code blocks.
1553
1554         * Makefile.in: Add sim_jump flag to those passed to igen.
1555
1556         * configure.in: New option --enable-sim-jump (default disabled)
1557
1558         * ppc-instructions: Eliminate any uses of labels and goto's.
1559         These result in duplicate declarations when a single flat function
1560         is being create.
1561
1562         * ppc-opcode-jump: New file.  Set of opcode rules useful when
1563         testing jumping idecodes.

1567         * gen-idecode.c: Optionally include the semantic code for an
1568         instruction in the function that is doing the decoding.
1569
1570         * igen.c: Add option (-C) to generate semantics in the instruction
1571         decode functions.
1572
1573         * configure.in (--enable-sim-icache): Accept an option list such
1574         as 1024,define.  Add a new choice to the list - semantic - which
1575         will cause igen to generate instruction decode functions that
1576         include the corresponding semantic code.
1577
1578 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
1579
1580         * configure.in: New option --enable-sim-line-nr (default enabled).
1581         Enable/disable the inclusion of CPP line directives in the
1582         generated files.  Such directives refer back to the source files
1583         used when generating the simulator code.
1584
1585         * Makefile.in (sim_line_nr): Pass to igen.
1586
1587 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
1588
1589         * igen.c (main): Revamp the options so that more letters are
1590         available.
1591
1592         * configure.in: Adjust to match igen's revamped options
1593
1594 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
1595
1596         * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
1597         that they use the same technique as igen (ie a dummy targets
1598         tmp-pk and tmp-hw are created).
1599

1635         * Makefile.in (filter.o): Adjust
1636         * configure.in: Adjust filter flag so that default includes 32bit
1637         and floating point.

1664
1665         * device_table.h: Don't pass the parent device into a devices

1706
1707         * corefile.c (core_create, core_from_device): Break core_create

1734         * configure.in: Check for whether the termios and termio
1735         structures are really defined, and whether or not, they define the

1737         * configure: Regenerate.
1738
1739         * Makefile.in ({,TERMIO_}CFLAGS): Add TERMIO_CFLAGS options set by

2481
2482         * debug.c (trace_usage): Add more detailed help.
2483         * device.c (device_usage): New. Output help including a list of
2484         the devices currently available in the device table.
2485         * device_table.c: Add usage operator to each device.
2486
2487         * corefile.c (core_create, core_device_create): Adjust so that the
2488         core device is created earlier for psim_tree().  Core can later be
2489         created from it.
2490
2491         * psim.c (psim_create): Update to handle above way of creating
2492         things.  Extract all information from the device tree.
2493

2499
2500         * debug.h: Add trace_print_info, trace_print_device_tree and
2501         trace_dump_device_tree.  The first is a replacement for the

2503         two enable the dumping of the entire device tree.
2504
2505         * debug.c: Add to trace_description table.
2506
2507         * main.c (main): Use above trace instead of local variable

2509
2510         * device.c (device_tree_print_device): New.  Prints the device
2511         tree in a format that is consistent with what can be parsed by the
2512         device tree load from file code.
2513
2514         * psim.c (psim_create): Dump device tree if enabled. If nump
2515         selected, exit psim immediatly.

2518
2519         * corefile-n.h (core_map_read_N): When mapping from an address to
2520         a device, do not subtract the devices base.  The device its self
2521         can do this.  Brings the behavour into line with OpenBoot.

2531
2532         * device.c (attach_device_interrupt_edge): New. Interrupt model
2533         did not allow interrupts to be wired up as a general net (edges).
2534         Re-implement so that interrupt events can be passed to multiple
2535         controllers and interrupt controllers can further propogate
2536         interrupt events.
2537
2538         * device.c (attach_device_interrupt_edge) : New, Ditto

2558 Wed Jan 17 18:18:40 1996  Andrew Cagney  <cagney@highland.com.au>
2559
2560         * device.c (external_to_device) : New function that provides a
2561         standard mapping between a devices internal representation (a
2562         pointer) and its external (or what is passed to a client)
2563         representation (a phandle).  Implement using the cap object
2564         attached to the root node.
2565
2566         * device.c (device_to_external) : Ditto
2567         * device.c (external_to_device_instance) : Ditto but for ihandle

2572
2573         * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
2574         needing to translate between internal and external representations
2575         changed to use the external_to_device et.al. device operations.
2576         * emul_chirp.c (chirp_emul_*) : Ditto
2577
2578         * Makefile (emul_chirp.o): Remove dependency on cap

2586
2587         * emul_generic.c (emul_write_buffer): Use vm faulting byte
2588         read/write calls for buffer transfers.  This will cause a fault to
2589         occure if the transfer fails.  CHRP catches the fault while the
2590         others suffer the consequences.
2591         (emul_read_buffer): Ditto.
2592         (emul_write_word): Ditto.
