111    Description:
112    
113    Minor fix to ml-ulex backend for regexps that match any character

381    Description:
382    
383    - Aaron: fixed a number of bugs in ml-ulex.
384    - Matthias:
385       - added CM control "cm.force-tools"; this is false by default;
386         when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
387         will be forced to run regardless of whether or not their targets
388         are up-to-date
389       - changed installer code so that config/install.sh will re-build
390         heap images for all tools even if those heap images already existed

396    
397    After Aaron Turon's bug fix for ml-ulex (handling the ^ character
398    in legacy mode), re-ran the lexer generator on all lex input files
399    and committed the results.
400    
401    This should fix the problem with ckit and nlffi that was reported
402    by Vesa A. Norrman.

416    Description:
417    
418    3rd merge of base from primop-branch-3 into the trunk.
419    Additional bug fixes included:
420    
421     * Timer.cpu_timer, etc. type printing corrected (by making
422         Timer have opaque sig constraint in basis/Implementation/timer.sml)
423     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
424         Stefan Monnier)

428    Date: 2007/05/31 11:40:00 CDT
429    Description:
430    
431    Fixed some bugs in new Div code in FLINT/trans/translate.sml.
432    
433    Also, changed the handling of "no core access":  When translate.sml
434    needs access to a core exception at a time when the core has not
435    been set up yet (this only happens when compiling system/smlnj/init/*),
436    then don't bother generating the corresponding tests.
437    
438    The old scheme was to generate a bogus value to be used in place of
439    the exception.  Unfortunately, that confuses the plambda type checker.
440    Moreover, it does not do any good, because at runtime we don't expect
441    such an exception to be ever raised.  (The code in system/smlnj/init/*
442    has to be written very carefully with this in mind!)

454    Description:
455    
456    FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
457    with an explicit test for zero division.  This should fixes several
458    regressions and makes it possible for downstream optimization phases
459    to treat these operations as "pure" when they are applied to unsigned
460    operands.

486    NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
487    
488      (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
489       CM_SLAVE_MODE is defined in attached slaves while running CM.make
490       or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
491       while running CMB.make.  The point is that the single symbol
492       NO_PLUGINS is definde in all three cases.)
493    
494    I changed the three locations within the sources that get compiled
495    during CMB.make where ml-yacc or ml-lex input is processed: When
496    NO_PLUGINS defined, then the use of the mlyacc and mllex tools
497    is bypassed.
498    
499    When bootstrapping new versions of the compiler, there can be
500    situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
501    are not available or otherwise not operational.  In this case one can
502    manually define the NO_PLUGINS symbol prior to running CMB.make().  To
503    do so, the following command should be issued at the interactive
504    prompt:
505    
506       #set (CMB.symval "NO_PLUGINS") (SOME 1);
507    
508    A CMB.make with NO_PLUGINS defined relies on the existence of the
509    files that normally would be generated by ml-yacc and ml-lex.
510    (Copies of these files are in the repository.)

527    
528    Changed the installation mechanism for CM tool plugins.  These are
529    just libaries and now get installed like ordinary libaries.
530    
531    There are now a number of new installation targets that give some
532    fine-grain control over what classes and suffixes are known, and what
533    they will map to.
534    See config/targets for details.
535    
536    The code that caused plugin installation as part of running a
537    tool's "build" script has been removed.  (The build script is for
538    building, not for installing.)

544    
545    Added a boolean control named cm.tolerate-tool-failures (env. variable
546    name: CM_TOLERATE_TOOL_FAILURES).  The default is false and makes
547    CM fail if a shell tool reports a non-success exit status.  If
548    the control is set to true, then CM will press on after tool failures
549    in the event that the target files exist (even though they are
550    considered outdated).  Turning the control to true can be useful for
551    bootstrapping.

556    Description:
557    
558    Merge of ml-lpt revisions for 110.64.
559    
560    The name of several ml-lpt-lib modules has changed:
561      Repair        => AntlrRepair
562      StreamPos     => AntlrStreamPos
563      ErrHandlerFn  => AntlrErrHandler
564      EBNF          => AntlrEBNF
565    
566    The ml-antlr specification format has changed: declarations such as
567    %tokens and nonterminal definitions can occur *multiple* times in the
568    same specification.  The semantics are such that each new declaration
569    extends the previous ones.  This does not apply to %start or %name,
570    of course.
571    
572    Importing a grammar via %import now includes *all* declarations in from
573    the imported grammar, except for %name, %entry, and %start.  Tokens
574    and nonterminals can be dropped using the new %dropping clause of the
575    %import directive; the separate %drop and %extend have been removed.
576    
577    We now allow optional type annotations on nonterminals, using the %nonterms
578    directive as in ml-yacc.
579    
580    The refcell construct is now implemented using SML's regular reference
581    cells, so the :== and !! notation has been deprecated.
582    
583    The ml-antlr tool now does much more checking of specifications, and
584    its error messages have been greatly improved.  Error repair for
585    generated parsers has been completely rewritten, and is now both
586    much faster and more accurate.
587    
588    ml-ulex is now more lenient with escape codes (non-SML-standard
589    escape codes are now interpreted literally, so e.g. \| denotes "|").
590    Also, character classes may now include a "-" character at the beginning
591    as is standard in most other regexp tools.
592    
593    All of these changes are documented in the user guide, which has
594    been updated and improved with this merge.

748    for specifying calling conventions (see

750    Initially, we plan to use this code to generate C calls for the AMD64.

752    The staged allocation code base resides in MLRISC/staged-allocation,
753    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

820    Brought ml-lpt manual up-to-date with the code.  Many minor

822    ml-lpt-lib for integration with new UTF8 structure.  Changed
823    the interface for creating streams in ml-ulex (we now support
824    stream creation from several kinds of sources).  Overall, the
825    tools are now quite stable, and their interfaces are unlikely to
826    change in a way that would break compatibility.  More work,
827    however, is needed in the documentation.

834    Implemented library installer.  Moved CM plugin code for

837    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
838    and ml-antlr.
839    
840    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
841    CM tools.  (It turns out to be too messy to do otherwise because
842    there is too much code that during installation relies on the presence
843    of these tools -- resulting in a tricky ordering problem.)

850    Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
851    Modified CM's startup code to use shiftArgs as it processes
852    command line arguments.  This way, the init code in each .sml-file
853    or library that is mentioned at the top level will see only
854    those arguments that have not yet been processed at this point.
855    In other words, the init code can "seize control" and process the
856    remaining command line.

923    Description:
924    
925    Added code to CM's "standard shell tool" implementation which
926    causes it to tolerate (with a warning) the situation where the shell
927    command fails (e.g., due to the shell command's non-existence)
928    as long as all target files exist.
929    
930    This makes it possible to, e.g., build ml-yacc from sources even if
931    svn checkout messed up the time stamps on files in such a way that
932    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
933    be needed to re-process yacc.grm, but obviously it might not yet be
934    available at that time.)

974    Description:
975    
976    New working release (110.60).  NEW BOOTFILES!
977    
978    This is the first subversion-hosted release.  There are also changes
979    to the directory layout.  Here is a table:
980    
981    (All pathnames are relative to the SML/NJ "root" directory.)
982    
983      config -> config
984    
985      src/cm -> base/cm
986      src/compiler -> base/compiler
987      src/runtime -> base/runtime
988      src/system -> base/system
989    
990      src/cm/pgraph -> pgraph
991    
992      src/READMES -> base/READMES
993      src/$notefile -> base/NOTES/$notefile
994         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
995                           MACOSXINSTALL WININSTALL
996    
997      src/smlnj-lib -> smlnj-lib
998      src/MLRISC -> MLRISC
999      ckit -> ckit
1000      src/cml -> cml
1001      src/eXene -> eXene
1002      src/heap2asm -> heap2asm
1003      src/lexgen -> lexgen
1004      src/ml-burg -> ml-burg
1005      src/ml-lex -> ml-lex
1006      src/ml-yacc -> ml-yacc
1007      src/ml-nlffi-lib -> nlffi/lib
1008      src/ml-nlffigen -> nlffi/gen
1009      src/smlnj-c -> smlnj-c
1010      src/tools/TraceDebugProf -> trace-debug-profile
1011    
1012    In addition, there is also a new
1013    
1014      ml-lpt
1015    
1016    directory containing two new program generator tools: ml-ulex and
1017    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1018    LL(k) parser generator). These tools are currently "beta-quality"
1019    
1020    The latest versios of the sources can now be obtained anonymously
1021    via subversion.  For this, it is useful to first check out
1022    
1023       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1024    
1025    and put the resulting directory on your shell's PATH.  This provides
1026    access to three shell scripts: checkout-all.sh, stat-all.sh,
1027    and refresh-all.sh.
1028    
1029    To create a freshly checked-out copy of the sources, do
1030    
1031       checkout-all.sh [dir]
1032    
1033    where dir is the optional SML/NJ root directory (default is ".").
1034    
1035    This creates the above directory layout.  Each subdirectory of
1036    the root is under individual subversion control.  The stat-all.sh
1037    and refresh-al.sh scripts apply "svn stat" or "svn update" to
1038    each of these subtrees.
1039

1042    Date: 2006/11/02 12:20:00 CST
1043    Description:
1044    
1045    Reorganized directory layout.
1046    
1047    This is a temporary solution, more reorganization is to come.
1048    
1049    The basic idea is to have a number of toplevel trees, each corresponding
1050    to a well-defined part of the overall system.  Each part can be
1051    maintained individually, even in separate source repositories,
1052    although currently we still serve everything out of the main
1053    smlnj-gforge tree.
1054    
1055    Installer and and scripts have been updated to reflect the new
1056    layout.  The installer (base/src/system/smlnj/installer) is now
1057    "scriptable" to avoid burning too much knowledge about the
1058    layout into SML source code.  The main script used by the installer
1059    is in config/actions.
1060    
1061    The main change is that many of the subdirectories of what used to
1062    be known as "src" have moved to the toplevel.  The "src" directory
1063    itself has moved down into a subtree called "base".  (We may eventually
1064    get rid of the extra level of indirection represented by "src".)
1065    
1066    The layout is now as follows:
1067    
1068      toplevel tree name | default repository
1069                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1070      -------------------+----------------------------------------------------
1071      config             | $gf/config/trunk
1072                         |
1073      base               | $gf/sml/trunk
1074                         |
1075      smlnj-lib          | $gf/smlnj-lib/trunk
1076      MLRISC             | $gf/MLRISC/trunk
1077                         |
1078      ml-yacc            | $gf/ml-yacc/trunk
1079      ml-lex             | $gf/ml-lex/trunk
1080      ml-burg            | $gf/ml-burg/trunk
1081      lexgen             | $gf/lexgen/trunk
1082      heap2asm           | $gf/heap2asm/trunk
1083                         |
1084      cml                | $gf/cml/trunk
1085      eXene              | $gf/eXene/trunk
1086      ckit               | $gf/ckit/trunk
1087      nlffi              | $gf/nlffi/trunk
1088                         |
1089      smlnj-c            | $gf/smlnj-c/trunk
1090    
1091    In $gf/admin there are a few useful shell scripts for checking out
1092    and maintaining the entire collection of trees:
1093    
1094       admin/checkout-all.sh [dir]
1095          -- optionally creates dir and checks out all trees from their
1096             default repositories; if dir is missing, checkout into .
1097       admin/refresh-all.sh [dir]
1098          -- looks at all trees (from the above list) in dir (default: .)
1099             and runs "svn update" if the tree exists and is under
1100             subversion control;
1101             non-existing or non-subversion trees are skipped
1102       admin/stat-all.sh [dir]
1103          -- like refresh-all.sh, but runs "svn stat" instead

1120    New working version (110.59).  NEW BOOTFILES!
1121    
1122    I am freezing 110.59.  Changes other than the version-number increase:
1123    
1124      eXene:
1125    
1126         * committed changes to eXene from Alley Stoughton:
1127             "fixed bugs in X authorization and resource handling, as well
1128              as in the pile and viewport widgets"
1129    
1130      Runtime:
1131        * fixed linking problem with NetBSD 3.x.
1132    
1133      Lexgen:
1134        * lexgen tool handles non-ascii characters in 7-bit mode the same
1135          way that ml-lex does
1136    
1137        * lexgen propagates exceptions the same way that ml-lex does
1138    
1139      CML:
1140        * Fixed a bug in the SyncVar polling functions (iGetPoll,
1141          mTakePoll, and mGetPoll) that could lead to livelock.

1252    (This is a temporary solution which relies on the fact that the

1254    intel mac from generic x86 unix code and make separate sets of binaries.)

1285    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
1286    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
1287    at the time when config/preloads is processed, the library has to
1288    be referred to by another name.  In 110.57 this would be
1289    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
1290    to be valid as well.)

1346    Description:
1347    
1348    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
1349    file gets loaded as a tool -- by the equivalent of CM.make during the
1350    run of CMB.make.  Thus, CMB's path configuration is meaningless for
1351    it.  Instead, it has the status of "user code", so it should use
1352    $/basis.cm to refer to the Basis library.  (At least that's true for
1353    the purpose of bootstrapping the previous change.  In the future it
1354    might make sense to have versiontool.cm refer to
1355    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1356    compiler itself uses.)
1357    
1358    Also patched src/system/testml to have it activate those extra anchor
1359    bindings in config/extrapathconfig.

1387    This makes it possible to work with code that requires different
1388    versions of these libraries, and which refers to these libraries using
1389    their "default" names (i.e., the first set of names above).  In other
1390    words, one can un-define or re-define those default names without
1391    compromising the proper functioning of the compiler itself.
1392    
1393    A similar procedure had already been performed for several of the
1394    MLRISC libraries that are linked into the compiler.  I did some
1395    cleanup on this code.
1396    
1397    A new file in the config directory (named extrapathconfig) is
1398    responsible for setting up path anchors that the compiler itself does
1399    not need, but that are typically required by user code.

1578    Tag: blume-20050516-redump-heap
1579    Description:
1580    
1581    Added mechanism for re-creating a heap file for the interactive system
1582    after configuration variables have been changed.
1583    
1584       CM.redump_heap : string -> unit
1585    
1586    This is much like SMLofNJ.exportML, but starting from the resulting
1587    heap does not return to the caller of CM.redump_heap but
1588    restarts the interactive system from scratch.  The original call of
1589    CM.redump_heap does not return but ends the interactive session.
1590    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1591    
1592    Internally, redump_heap winds the dynamic execution context back to
1593    the point where the original heap image was created and re-executes
1594    the heap image generation code in the boot code.

1710    Tag: blume-20050114-heap2exec
1711    Description:
1712    
1713    Implemented new (but still experimental) heap2exec facility.  This is
1714    tested under Mac OS X and should work under Linux (will test shortly).
1715    It will probably also work on the Sparc (will test some time later).
1716    
1717      - removed old "HACKED_STANDALONE" hack from runtime
1718    
1719    To be able to test this, uncomment the request for "heap2asm" in
1720    config/targets prior to installation.  (Notice that this is different
1721    from "heap2exec" mentioned below.  Not a typo.)
1722    
1723    To perform an actual test, run the command
1724    
1725       $ bin/heap2exec heapfile execfile
1726    
1727    (You can put heap2exec on your shell's path.)
1728    
1729    For example, run
1730    
1731      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1732    
1733    This will create a standalone executable called "mly" which you can
1734    then invoke directly as a command.

1830    Description:
1831    
1832    Hacked some of the scripts (in particular: the installer) to cope with
1833    spaces in filenames a bit better.  But beware: the current "solution"
1834    is likely still full of bugs and inherently incomplete.  (We need to
1835    do away with those shell scripts for a comprehensive solution.)

1879    Tag: blume-20041124-position
1880    Description:
1881    
1882    The compiler can now be compiled in a mode that makes structure Position
1883    equal to Int64.  The default, however, is unchanged (Position = Int31)
1884    for the time being.
1885    
1886    To enable 64-bit positions, use the following procedure:
1887    
1888    1. Start sml
1889    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1890    3. Type
1891          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1892    4. Run CMB.make() as usual.
1893    
1894    This is barely tested.  The only test so far was a little SML program
1895    counting the number of characters in an 8-gigabyte file by
1896    reading it character-by-character.  That test was successful.
1897    
1898    In support of 64-bit positions, a number of new functions have been
1899    added to the runtime system.

1940    Description:
1941    
1942    - Stripped down the versiontool: It now only handles the version number.
1943      The date string is generated at bootstrap time (during makeml).
1944    
1945    - In a previous commit, fixed a minor issue with how polyequal is being
1946      translated.  In particular, the code now "looks through" abstractions.
1947      This results in slightly fewer polyEqual warnings and hopefully slightly
1948      more efficient code.  Important examples for where this matters are
1949      the new int64 and word64 types.

1964    Description:
1965    
1966    All the pieces of Word64 are now there, with the exception of the
1967    conversions from and to LargeWord. (Eventually these need to be identities,
1968    but for the time being they don't even make sense because LargeWord is
1969    32-bit wide.)
1970    
1971    Also started to add similar support for Int64, but major pieces of that
1972    are still missing.

1977    Tag: blume-20041111-word64
1978    Description:
1979    
1980    Structure Word64 is now (almost) complete, word literals and patterns
1981    seem to work.  There are a few odd pieces missing.  In particular,
1982    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1983    at the moment.
1984    
1985    Making Word64 official would mean that LargeWord becomes Word64.  But
1986    this requires extreme care because most word-word conversions have to
1987    go through LargeWord, so making a mistake means loss of efficiency or
1988    worse.  Eventually there will be a solution similar to (but actually
1989    simpler than) what I did with IntInf.

2017                 =====================
2018    
2019    Also:
2020    
2021      - Changend config/srcarchiveurl from a file just
2022        containing the URL string into a file containing
2023        shell script code.  The code has access to the $VERSION variable.
2024      - Made corresponding changes to config/install.sh and config/unpack.
2025      - Default contents of config/srcarchiveurl uses $VERSION and
2026        normally does not have to be edited to reflect a version change.
2027    
2028      (As a result, a version change can be done by just editing
2029       config/version, the rest is now automatic.)

2044    Description:
2045    
2046    This is the HISTORY entry for two earlier commits, both concerning
2047    the x86 c-calls code in MLRISC:
2048    
2049      - added a missing LOAD in the code that deals with struct arguments
2050      - made sure the caller does not add the wrong number of bytes to the
2051        stack pointer after a call of a function returning a struct
2052        (the callee already pops the implicit argument which points to
2053         the space reserved for the result)
