479    - Aaron: fixed a number of bugs in ml-ulex.
480    - Matthias:
481       - added CM control "cm.force-tools"; this is false by default;
482         when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
483         will be forced to run regardless of whether or not their targets
484         are up-to-date
485       - changed installer code so that config/install.sh will re-build
486         heap images for all tools even if those heap images already existed

513    
514    3rd merge of base from primop-branch-3 into the trunk.
515    Additional bug fixes included:
516    
517     * Timer.cpu_timer, etc. type printing corrected (by making
518         Timer have opaque sig constraint in basis/Implementation/timer.sml)
519     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by

525    Description:
526    
527    Fixed some bugs in new Div code in FLINT/trans/translate.sml.
528    
529    Also, changed the handling of "no core access":  When translate.sml
530    needs access to a core exception at a time when the core has not
531    been set up yet (this only happens when compiling system/smlnj/init/*),
532    then don't bother generating the corresponding tests.
533    
534    The old scheme was to generate a bogus value to be used in place of
535    the exception.  Unfortunately, that confuses the plambda type checker.
536    Moreover, it does not do any good, because at runtime we don't expect
537    such an exception to be ever raised.  (The code in system/smlnj/init/*
538    has to be written very carefully with this in mind!)

552    FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
553    with an explicit test for zero division.  This should fixes several
554    regressions and makes it possible for downstream optimization phases
555    to treat these operations as "pure" when they are applied to unsigned
556    operands.

579    Description:
580    
581    CMB (and CM) now automatically defines the CM "preprocessor" symbol
582    NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
583    
584      (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
585       CM_SLAVE_MODE is defined in attached slaves while running CM.make
586       or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
587       while running CMB.make.  The point is that the single symbol
588       NO_PLUGINS is definde in all three cases.)
589    
590    I changed the three locations within the sources that get compiled
591    during CMB.make where ml-yacc or ml-lex input is processed: When
592    NO_PLUGINS defined, then the use of the mlyacc and mllex tools
593    is bypassed.
594    
595    When bootstrapping new versions of the compiler, there can be
596    situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
597    are not available or otherwise not operational.  In this case one can
598    manually define the NO_PLUGINS symbol prior to running CMB.make().  To
599    do so, the following command should be issued at the interactive
600    prompt:
601    
602       #set (CMB.symval "NO_PLUGINS") (SOME 1);
603    
604    A CMB.make with NO_PLUGINS defined relies on the existence of the
605    files that normally would be generated by ml-yacc and ml-lex.
606    (Copies of these files are in the repository.)

623    
624    Changed the installation mechanism for CM tool plugins.  These are
625    just libaries and now get installed like ordinary libaries.
626    
627    There are now a number of new installation targets that give some
628    fine-grain control over what classes and suffixes are known, and what
629    they will map to.
630    See config/targets for details.
631    
632    The code that caused plugin installation as part of running a
633    tool's "build" script has been removed.  (The build script is for
634    building, not for installing.)

640    
641    Added a boolean control named cm.tolerate-tool-failures (env. variable
642    name: CM_TOLERATE_TOOL_FAILURES).  The default is false and makes
643    CM fail if a shell tool reports a non-success exit status.  If
644    the control is set to true, then CM will press on after tool failures
645    in the event that the target files exist (even though they are
646    considered outdated).  Turning the control to true can be useful for
647    bootstrapping.

652    Description:
653    
654    Merge of ml-lpt revisions for 110.64.
655    
656    The name of several ml-lpt-lib modules has changed:
657      Repair        => AntlrRepair
658      StreamPos     => AntlrStreamPos
659      ErrHandlerFn  => AntlrErrHandler
660      EBNF          => AntlrEBNF
661    
662    The ml-antlr specification format has changed: declarations such as
663    %tokens and nonterminal definitions can occur *multiple* times in the
664    same specification.  The semantics are such that each new declaration
665    extends the previous ones.  This does not apply to %start or %name,
666    of course.
667    
668    Importing a grammar via %import now includes *all* declarations in from
669    the imported grammar, except for %name, %entry, and %start.  Tokens
670    and nonterminals can be dropped using the new %dropping clause of the
671    %import directive; the separate %drop and %extend have been removed.
672    
673    We now allow optional type annotations on nonterminals, using the %nonterms
674    directive as in ml-yacc.
675    
676    The refcell construct is now implemented using SML's regular reference
677    cells, so the :== and !! notation has been deprecated.
678    
679    The ml-antlr tool now does much more checking of specifications, and
680    its error messages have been greatly improved.  Error repair for
681    generated parsers has been completely rewritten, and is now both
682    much faster and more accurate.
683    
684    ml-ulex is now more lenient with escape codes (non-SML-standard
685    escape codes are now interpreted literally, so e.g. \| denotes "|").
686    Also, character classes may now include a "-" character at the beginning
687    as is standard in most other regexp tools.
688    
689    All of these changes are documented in the user guide, which has
690    been updated and improved with this merge.

707    
708    Preliminary commit of large ml-lpt revisions (more to come for 110.64).
709    The ml-antlr specification format has changed: declarations such as
710    %tokens and nonterminal definitions can occur *multiple* times in the
711    same specification.  The semantics are such that each new declaration
712    extends the previous ones.  Grammar extension constructs have also
713    changed.  We now allow type annotations on nonterminals.  Finally,
714    the refcell construct is now implemented using SML's regular reference
715    cells, so the :== and !! notation has been deprecated.  All of these
716    changes will appear in the 110.64 user guide for ml-lpt.
717    
718    The ml-antlr tool now does much more checking of specifications, and
719    its error messages have been greatly improved.  There has also been
720    some work on the error repair process for generated parsers, but this
721    will be further improved in 110.64.

812    Added preliminary support in MLRISC for Staged Allocation, a technique
813    for specifying calling conventions (see
814    http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
815    Initially, we plan to use this code to generate C calls for the AMD64.
816    
817    The staged allocation code base resides in MLRISC/staged-allocation,
818    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

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

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

898    
899    Implemented library installer.  Moved CM plugin code for
900    ml-burg, ml-lex, and ml-yacc out of CM source tree and into
901    their respective trees.  Implemented CM plugin for ml-ulex
902    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
903    and ml-antlr.
904    
905    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
906    CM tools.  (It turns out to be too messy to do otherwise because
907    there is too much code that during installation relies on the presence
908    of these tools -- resulting in a tricky ordering problem.)

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

979    Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to
980    get the c_cc termios data copied correctly.  Also moved the allocation
981    of the string to avoid problems if it caused a GC.
982    
983    Thanks to Timothy Bourke for the bug report and fix.

988    Description:
989    
990    Added code to CM's "standard shell tool" implementation which
991    causes it to tolerate (with a warning) the situation where the shell
992    command fails (e.g., due to the shell command's non-existence)
993    as long as all target files exist.
994    
995    This makes it possible to, e.g., build ml-yacc from sources even if
996    svn checkout messed up the time stamps on files in such a way that
997    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
998    be needed to re-process yacc.grm, but obviously it might not yet be
999    available at that time.)

1039    Description:
1040    
1041    New working release (110.60).  NEW BOOTFILES!
1042    
1043    This is the first subversion-hosted release.  There are also changes
1044    to the directory layout.  Here is a table:
1045    
1046    (All pathnames are relative to the SML/NJ "root" directory.)
1047    
1048      config -> config
1049    
1050      src/cm -> base/cm
1051      src/compiler -> base/compiler
1052      src/runtime -> base/runtime
1053      src/system -> base/system
1054    
1055      src/cm/pgraph -> pgraph
1056    
1057      src/READMES -> base/READMES
1058      src/$notefile -> base/NOTES/$notefile
1059         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1060                           MACOSXINSTALL WININSTALL
1061    
1062      src/smlnj-lib -> smlnj-lib
1063      src/MLRISC -> MLRISC
1064      ckit -> ckit
1065      src/cml -> cml
1066      src/eXene -> eXene
1067      src/heap2asm -> heap2asm
1068      src/lexgen -> lexgen
1069      src/ml-burg -> ml-burg
1070      src/ml-lex -> ml-lex
1071      src/ml-yacc -> ml-yacc
1072      src/ml-nlffi-lib -> nlffi/lib
1073      src/ml-nlffigen -> nlffi/gen
1074      src/smlnj-c -> smlnj-c
1075      src/tools/TraceDebugProf -> trace-debug-profile
1076    
1077    In addition, there is also a new
1078    
1079      ml-lpt
1080    
1081    directory containing two new program generator tools: ml-ulex and
1082    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1083    LL(k) parser generator). These tools are currently "beta-quality"
1084    
1085    The latest versios of the sources can now be obtained anonymously
1086    via subversion.  For this, it is useful to first check out
1087    
1088       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1089    
1090    and put the resulting directory on your shell's PATH.  This provides
1091    access to three shell scripts: checkout-all.sh, stat-all.sh,
1092    and refresh-all.sh.
1093    
1094    To create a freshly checked-out copy of the sources, do
1095    
1096       checkout-all.sh [dir]
1097    
1098    where dir is the optional SML/NJ root directory (default is ".").
1099    
1100    This creates the above directory layout.  Each subdirectory of
1101    the root is under individual subversion control.  The stat-all.sh
1102    and refresh-al.sh scripts apply "svn stat" or "svn update" to
1103    each of these subtrees.
1104

1107    Date: 2006/11/02 12:20:00 CST
1108    Description:
1109    
1110    Reorganized directory layout.
1111    
1112    This is a temporary solution, more reorganization is to come.
1113    
1114    The basic idea is to have a number of toplevel trees, each corresponding
1115    to a well-defined part of the overall system.  Each part can be
1116    maintained individually, even in separate source repositories,
1117    although currently we still serve everything out of the main
1118    smlnj-gforge tree.
1119    
1120    Installer and and scripts have been updated to reflect the new
1121    layout.  The installer (base/src/system/smlnj/installer) is now
1122    "scriptable" to avoid burning too much knowledge about the
1123    layout into SML source code.  The main script used by the installer
1124    is in config/actions.
1125    
1126    The main change is that many of the subdirectories of what used to
1127    be known as "src" have moved to the toplevel.  The "src" directory
1128    itself has moved down into a subtree called "base".  (We may eventually
1129    get rid of the extra level of indirection represented by "src".)
1130    
1131    The layout is now as follows:
1132    
1133      toplevel tree name | default repository
1134                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1135      -------------------+----------------------------------------------------
1136      config             | $gf/config/trunk
1137                         |
1138      base               | $gf/sml/trunk
1139                         |
1140      smlnj-lib          | $gf/smlnj-lib/trunk
1141      MLRISC             | $gf/MLRISC/trunk
1142                         |
1143      ml-yacc            | $gf/ml-yacc/trunk
1144      ml-lex             | $gf/ml-lex/trunk
1145      ml-burg            | $gf/ml-burg/trunk
1146      lexgen             | $gf/lexgen/trunk
1147      heap2asm           | $gf/heap2asm/trunk
1148                         |
1149      cml                | $gf/cml/trunk
1150      eXene              | $gf/eXene/trunk
1151      ckit               | $gf/ckit/trunk
1152      nlffi              | $gf/nlffi/trunk
1153                         |
1154      smlnj-c            | $gf/smlnj-c/trunk
1155    
1156    In $gf/admin there are a few useful shell scripts for checking out
1157    and maintaining the entire collection of trees:
1158    
1159       admin/checkout-all.sh [dir]
1160          -- optionally creates dir and checks out all trees from their
1161             default repositories; if dir is missing, checkout into .
1162       admin/refresh-all.sh [dir]
1163          -- looks at all trees (from the above list) in dir (default: .)
1164             and runs "svn update" if the tree exists and is under
1165             subversion control;
1166             non-existing or non-subversion trees are skipped
1167       admin/stat-all.sh [dir]
1168          -- like refresh-all.sh, but runs "svn stat" instead

1187    I am freezing 110.59.  Changes other than the version-number increase:
1188    
1189      eXene:
1190    
1191         * committed changes to eXene from Alley Stoughton:
1192             "fixed bugs in X authorization and resource handling, as well
1193              as in the pile and viewport widgets"
1194    
1195      Runtime:
1196        * fixed linking problem with NetBSD 3.x.
1197    
1198      Lexgen:
1199        * lexgen tool handles non-ascii characters in 7-bit mode the same
1200          way that ml-lex does
1201    
1202        * lexgen propagates exceptions the same way that ml-lex does
1203    
1204      CML:
1205        * Fixed a bug in the SyncVar polling functions (iGetPoll,
1206          mTakePoll, and mGetPoll) that could lead to livelock.

1350    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
1351    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
1352    at the time when config/preloads is processed, the library has to
1353    be referred to by another name.  In 110.57 this would be
1354    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
1355    to be valid as well.)

1410    Tag: blume-22051115-versiontool
1411    Description:
1412    
1413    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
1414    file gets loaded as a tool -- by the equivalent of CM.make during the
1415    run of CMB.make.  Thus, CMB's path configuration is meaningless for
1416    it.  Instead, it has the status of "user code", so it should use
1417    $/basis.cm to refer to the Basis library.  (At least that's true for
1418    the purpose of bootstrapping the previous change.  In the future it
1419    might make sense to have versiontool.cm refer to
1420    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1421    compiler itself uses.)
1422    
1423    Also patched src/system/testml to have it activate those extra anchor
1424    bindings in config/extrapathconfig.

1429    Tag: blume-22051115-libraries
1430    Description:
1431    
1432    This change affects the way the following libraries are tied into
1433    the system:
1434    
1435       $/basis.cm
1436       $/smlnj-lib.cm
1437       $/pp-lib.cm
1438       $/controls-lib.cm
1439       $/html-lib.cm
1440       $/ml-yacc-lib.cm
1441    
1442    These libraries are now internally (as seen from the source code
1443    of the implementation itself) known by the following names:
1444    
1445       $smlnj/basis/basis.cm
1446       $smlnj/smlnj-lib/smlnj-lib.cm
1447       $smlnj/smlnj-lib/pp-lib.cm
1448       $smlnj/smlnj-lib/controls-lib.cm
1449       $smlnj/smlnj-lib/html-lib.cm
1450       $smlnj/ml-yacc/ml-yacc-lib.cm
1451    
1452    This makes it possible to work with code that requires different
1453    versions of these libraries, and which refers to these libraries using
1454    their "default" names (i.e., the first set of names above).  In other
1455    words, one can un-define or re-define those default names without
1456    compromising the proper functioning of the compiler itself.
1457    
1458    A similar procedure had already been performed for several of the
1459    MLRISC libraries that are linked into the compiler.  I did some
1460    cleanup on this code.
1461    
1462    A new file in the config directory (named extrapathconfig) is
1463    responsible for setting up path anchors that the compiler itself does
1464    not need, but that are typically required by user code.

1643    Tag: blume-20050516-redump-heap
1644    Description:
1645    
1646    Added mechanism for re-creating a heap file for the interactive system
1647    after configuration variables have been changed.
1648    
1649       CM.redump_heap : string -> unit
1650    
1651    This is much like SMLofNJ.exportML, but starting from the resulting
1652    heap does not return to the caller of CM.redump_heap but
1653    restarts the interactive system from scratch.  The original call of
1654    CM.redump_heap does not return but ends the interactive session.
1655    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1656    
1657    Internally, redump_heap winds the dynamic execution context back to
1658    the point where the original heap image was created and re-executes
1659    the heap image generation code in the boot code.

1775    Tag: blume-20050114-heap2exec
1776    Description:
1777    
1778    Implemented new (but still experimental) heap2exec facility.  This is
1779    tested under Mac OS X and should work under Linux (will test shortly).
1780    It will probably also work on the Sparc (will test some time later).
1781    
1782      - removed old "HACKED_STANDALONE" hack from runtime
1783    
1784    To be able to test this, uncomment the request for "heap2asm" in
1785    config/targets prior to installation.  (Notice that this is different
1786    from "heap2exec" mentioned below.  Not a typo.)
1787    
1788    To perform an actual test, run the command
1789    
1790       $ bin/heap2exec heapfile execfile
1791    
1792    (You can put heap2exec on your shell's path.)
1793    
1794    For example, run
1795    
1796      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1797    
1798    This will create a standalone executable called "mly" which you can
1799    then invoke directly as a command.

1839    files.

1845    Description:
1846    
1847        The Unix I/O library of SML/NJ on cygwin does not understand
1848    Windows style pathname, so problems arise when SMLNJ_HOME is set
1849    to a Windows style pathname.  _run-sml now converts SMLNJ_HOME
1850    to a POSIX pathname on cygwin.

1944    Tag: blume-20041124-position
1945    Description:
1946    
1947    The compiler can now be compiled in a mode that makes structure Position
1948    equal to Int64.  The default, however, is unchanged (Position = Int31)
1949    for the time being.
1950    
1951    To enable 64-bit positions, use the following procedure:
1952    
1953    1. Start sml
1954    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1955    3. Type
1956          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1957    4. Run CMB.make() as usual.
1958    
1959    This is barely tested.  The only test so far was a little SML program
1960    counting the number of characters in an 8-gigabyte file by
1961    reading it character-by-character.  That test was successful.
1962    
1963    In support of 64-bit positions, a number of new functions have been
1964    added to the runtime system.

2007    - Stripped down the versiontool: It now only handles the version number.
2008      The date string is generated at bootstrap time (during makeml).
2009    
2010    - In a previous commit, fixed a minor issue with how polyequal is being
2011      translated.  In particular, the code now "looks through" abstractions.
2012      This results in slightly fewer polyEqual warnings and hopefully slightly
2013      more efficient code.  Important examples for where this matters are
2014      the new int64 and word64 types.

2031    All the pieces of Word64 are now there, with the exception of the

2033    but for the time being they don't even make sense because LargeWord is
2034    32-bit wide.)
2035    
2036    Also started to add similar support for Int64, but major pieces of that
2037    are still missing.

2043  Description:  Description:
2044    
2045    Structure Word64 is now (almost) complete, word literals and patterns
2046    seem to work.  There are a few odd pieces missing.  In particular,
2047    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2048    at the moment.
2049    
2050    Making Word64 official would mean that LargeWord becomes Word64.  But
2051    this requires extreme care because most word-word conversions have to
2052    go through LargeWord, so making a mistake means loss of efficiency or
2053    worse.  Eventually there will be a solution similar to (but actually
2054    simpler than) what I did with IntInf.

2089      - Made corresponding changes to config/install.sh and config/unpack.
2090      - Default contents of config/srcarchiveurl uses $VERSION and
2091        normally does not have to be edited to reflect a version change.
2092    
2093      (As a result, a version change can be done by just editing

2134    Tag: blume-20041020-standalone-backtrace
2135    Description:
2136    
2137    Added a mechanism for getting back-trace information from standalone
2138    programs.  Here is how it works:
2139    
2140       1. The part of the program from which you want to get backtrace
2141          information (usually the whole program) should be wrapped with
2142          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
2143          main program could be modified from something like
2144    
2145             fun main (pgm, args) = ...
2146    
2147         to
2148    
2149            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2150    
2151       2. To be able to access BackTrace.monitor, you have to add
2152          library $smlnj-tdp/plugins.cm to the .cm file that contains your
2153          main function.
2154    
2155       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2156          CM might have created in the past for your project).
2157    
2158       4. Build the system using this command line:
2159    
2160             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2161                      myprog.cm MyProg.main myprog
2162    
2163          instead of the usual
2164    
2165             ml-build myprog.cm MyProg.main myprog
2166    
2167    I changed a library name:
2168    
2169       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2170    
2171    New libraries:
2172    
2173       $smlnj-tdp/back-trace.cm
2174          -- when loaded causes the back-trace plugin to be installed
2175       $smlnj-tdp/coverage.cm
2176          -- when loaded causes the coverage plugin to be installed

2192    Description:
2193    
2194    * Test coverage tool added!
2195    * Further reorganization of tracing-, debugging-, and profiling support:
2196    
2197        - moved original BTImp -- now called BackTrace -- into a separate
2198          library called $/trace-debug-profile.cm
2199        - eliminated all mentions of BTrace from SMLofNJ.Internals
2200        - only the instrumentation mechanism is now left in the compiler proper
2201        - BackTrace module is a plugin which is NOT plugged in by default
2202        - Coverage module is another such plugin
2203    
2204    To get the benefits of any of these plugin modules, the code in
2205    question must be compiled with tdp instrumentation turned on.  This
2206    can be done by setting SMLofNJ.Internals.TDP.mode to true.
2207    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2208    
2209    Plugins are selected at link time.  (Pre-compiled instrumented code
2210    can be re-loaded with different plugins in effect.)  When an
2211    instrumented module is linked, whatever plugins are at that time
2212    enabled will come into effect for that module.
2213    
2214    To enable the back-trace plugin, load library $/trace-debug-profile.cm
2215    and invoke BackTrace.install() (e.g., from the interactive prompt).
2216    To enable the coverage plugin, load the same library and invoke
2217    Coverage.install().
2218    
2219    Back-traces are generated automatically on uncaught exceptions and
2220    when the code in question explicitly invokes BackTrace.trigger().
2221    
2222    Coverage (and execution frequency-) information must be queried
2223    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2275    treats subsequent occurrences of "group", "library", "source", "is",
2276    "*", and "-" as ordinary identifiers rather than keywords.
2277    
2278    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
2279    is supposed to accept a tool argument called "source", but this did
2280    not work because of the clash with the keyword.

2286    Description:
2287    
2288    Assorted cleanup work:
2289    
2290      - got rid of intstrmap in favor of using the library's
2291        hash table implementation
2292      - threw out most of the pathnames stuff, as it was not used anyway
2293      - simplified tokentable implementation
2294      - fixed some minor spelling errors

2300    Description:
2301    
2302    Cleaned up the absyn to reflect the invariant that HANDLE always
2303    carries a FNexp as part of the type definition.  This eliminates some
2304    superfluous sanity checks at runtime down the road.
2305    
2306    Some minor cleanup of the btrace code.

2312    Description:
2313    
2314    Added hack to make slave mode work in the presence of the version
2315    tool.  (Still, since the master does two passes over the code for
2316    CMB.make, the release number gets bumped twice when slaves are
2317    attached.  I don't know if this is worth fixing...)

2323    Description:
2324    
2325    * Moved the "version" magic into its own little library under
2326      src/system/smlnj/internal.  This avoids expensive reconstruction of
2327      a stable src/compiler/core.cm.
2328    
2329    * At the same time, structure CompilerVersion is now known as
2330      structure SMLNJVersion.
2331    
2332    * Arranged for the version tool to NOT kick in when rebuilding the system
2333      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
2334      Also, loading the versiontool does not work when rebuilding the system
2335      because CM is not properly initialized at that time.
