21    nlffi was updated to work on Windows. It needed to pass in the correct
22    value for the name of the kernel32 DLL to obtain 'base' bindings.
23    Additionally updated the README for the most basic nlffi sample with
24    what you need to do on MacOSX and on Windows to make it work.

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

220    After Aaron Turon's bug fix for ml-ulex (handling the ^ character
221    in legacy mode), re-ran the lexer generator on all lex input files
222    and committed the results.
223    
224    This should fix the problem with ckit and nlffi that was reported
225    by Vesa A. Norrman.

241    3rd merge of base from primop-branch-3 into the trunk.
242    Additional bug fixes included:

252    Description:
253    
254    Fixed some bugs in new Div code in FLINT/trans/translate.sml.
255    
256    Also, changed the handling of "no core access":  When translate.sml
257    needs access to a core exception at a time when the core has not
258    been set up yet (this only happens when compiling system/smlnj/init/*),
259    then don't bother generating the corresponding tests.
260    
261    The old scheme was to generate a bogus value to be used in place of
262    the exception.  Unfortunately, that confuses the plambda type checker.
263    Moreover, it does not do any good, because at runtime we don't expect
264    such an exception to be ever raised.  (The code in system/smlnj/init/*
265    has to be written very carefully with this in mind!)

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

299    A number of fixes related to the formatting of dates.  These include fixes

304    Name: Matthias Blume (http://www.tti-c.org/blume/)
305    Date: 2007/05/23 22:30:00 CDT
306    Description:
307    
308    CMB (and CM) now automatically defines the CM "preprocessor" symbol
309    NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
310    
311      (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
312       CM_SLAVE_MODE is defined in attached slaves while running CM.make
313       or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
314       while running CMB.make.  The point is that the single symbol
315       NO_PLUGINS is definde in all three cases.)
316    
317    I changed the three locations within the sources that get compiled
318    during CMB.make where ml-yacc or ml-lex input is processed: When
319    NO_PLUGINS defined, then the use of the mlyacc and mllex tools
320    is bypassed.
321    
322    When bootstrapping new versions of the compiler, there can be
323    situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
324    are not available or otherwise not operational.  In this case one can
325    manually define the NO_PLUGINS symbol prior to running CMB.make().  To
326    do so, the following command should be issued at the interactive
327    prompt:
328    
329       #set (CMB.symval "NO_PLUGINS") (SOME 1);
330    
331    A CMB.make with NO_PLUGINS defined relies on the existence of the
332    files that normally would be generated by ml-yacc and ml-lex.
333    (Copies of these files are in the repository.)

349    Description:
350    
351    Changed the installation mechanism for CM tool plugins.  These are
352    just libaries and now get installed like ordinary libaries.
353    
354    There are now a number of new installation targets that give some
355    fine-grain control over what classes and suffixes are known, and what
356    they will map to.
357    See config/targets for details.
358    
359    The code that caused plugin installation as part of running a
360    tool's "build" script has been removed.  (The build script is for
361    building, not for installing.)

366    Description:
367    
368    Added a boolean control named cm.tolerate-tool-failures (env. variable
369    name: CM_TOLERATE_TOOL_FAILURES).  The default is false and makes
370    CM fail if a shell tool reports a non-success exit status.  If
371    the control is set to true, then CM will press on after tool failures
372    in the event that the target files exist (even though they are
373    considered outdated).  Turning the control to true can be useful for
374    bootstrapping.

380    
381    Merge of ml-lpt revisions for 110.64.
382    
383    The name of several ml-lpt-lib modules has changed:
384      Repair        => AntlrRepair
385      StreamPos     => AntlrStreamPos
386      ErrHandlerFn  => AntlrErrHandler
387      EBNF          => AntlrEBNF
388    
389    The ml-antlr specification format has changed: declarations such as
390    %tokens and nonterminal definitions can occur *multiple* times in the
391    same specification.  The semantics are such that each new declaration
392    extends the previous ones.  This does not apply to %start or %name,
393    of course.
394    
395    Importing a grammar via %import now includes *all* declarations in from
396    the imported grammar, except for %name, %entry, and %start.  Tokens
397    and nonterminals can be dropped using the new %dropping clause of the
398    %import directive; the separate %drop and %extend have been removed.
399    
400    We now allow optional type annotations on nonterminals, using the %nonterms
401    directive as in ml-yacc.
402    
403    The refcell construct is now implemented using SML's regular reference
404    cells, so the :== and !! notation has been deprecated.
405    
406    The ml-antlr tool now does much more checking of specifications, and
407    its error messages have been greatly improved.  Error repair for
408    generated parsers has been completely rewritten, and is now both
409    much faster and more accurate.
410    
411    ml-ulex is now more lenient with escape codes (non-SML-standard
412    escape codes are now interpreted literally, so e.g. \| denotes "|").
413    Also, character classes may now include a "-" character at the beginning
414    as is standard in most other regexp tools.
415    
416    All of these changes are documented in the user guide, which has
417    been updated and improved with this merge.

468    %tokens and nonterminal definitions can occur *multiple* times in the
469    same specification.  The semantics are such that each new declaration
470    extends the previous ones.  Grammar extension constructs have also
471    changed.  We now allow type annotations on nonterminals.  Finally,
472    the refcell construct is now implemented using SML's regular reference
473    cells, so the :== and !! notation has been deprecated.  All of these
474    changes will appear in the 110.64 user guide for ml-lpt.
475    
476    The ml-antlr tool now does much more checking of specifications, and
477    its error messages have been greatly improved.  There has also been
478    some work on the error repair process for generated parsers, but this
479    will be further improved in 110.64.

486    More Basis fixes: The Char.fromString (etc.) functions did not handle
487    the "\uxxxx" escape sequence.  There is still an outstanding bug with
488    String.fromString the tail is a format escape.  I added a comment to
489    this effect in Basis/Implementation/string.sml.

570    Added preliminary support in MLRISC for Staged Allocation, a technique
571    for specifying calling conventions (see
572    http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
573    Initially, we plan to use this code to generate C calls for the AMD64.
574    
575    The staged allocation code base resides in MLRISC/staged-allocation,
576    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

642    
643    Brought ml-lpt manual up-to-date with the code.  Many minor
644    improvements to the tools, and a few minor bugfixes.  Prepared
645    ml-lpt-lib for integration with new UTF8 structure.  Changed
646    the interface for creating streams in ml-ulex (we now support
647    stream creation from several kinds of sources).  Overall, the
648    tools are now quite stable, and their interfaces are unlikely to
649    change in a way that would break compatibility.  More work,
650    however, is needed in the documentation.

657    Implemented library installer.  Moved CM plugin code for
658    ml-burg, ml-lex, and ml-yacc out of CM source tree and into
659    their respective trees.  Implemented CM plugin for ml-ulex
660    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
661    and ml-antlr.
662    
663    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
664    CM tools.  (It turns out to be too messy to do otherwise because
665    there is too much code that during installation relies on the presence
666    of these tools -- resulting in a tricky ordering problem.)

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

746    Description:
747    
748    Added code to CM's "standard shell tool" implementation which
749    causes it to tolerate (with a warning) the situation where the shell
750    command fails (e.g., due to the shell command's non-existence)
751    as long as all target files exist.
752    
753    This makes it possible to, e.g., build ml-yacc from sources even if
754    svn checkout messed up the time stamps on files in such a way that
755    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
756    be needed to re-process yacc.grm, but obviously it might not yet be
757    available at that time.)

798    
799    New working release (110.60).  NEW BOOTFILES!
800    
801    This is the first subversion-hosted release.  There are also changes
802    to the directory layout.  Here is a table:
803    
804    (All pathnames are relative to the SML/NJ "root" directory.)
805    
806      config -> config
807    
808      src/cm -> base/cm
809      src/compiler -> base/compiler
810      src/runtime -> base/runtime
811      src/system -> base/system
812    
813      src/cm/pgraph -> pgraph
814    
815      src/READMES -> base/READMES
816      src/$notefile -> base/NOTES/$notefile
817         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
818                           MACOSXINSTALL WININSTALL
819    
820      src/smlnj-lib -> smlnj-lib
821      src/MLRISC -> MLRISC
822      ckit -> ckit
823      src/cml -> cml
824      src/eXene -> eXene
825      src/heap2asm -> heap2asm
826      src/lexgen -> lexgen
827      src/ml-burg -> ml-burg
828      src/ml-lex -> ml-lex
829      src/ml-yacc -> ml-yacc
830      src/ml-nlffi-lib -> nlffi/lib
831      src/ml-nlffigen -> nlffi/gen
832      src/smlnj-c -> smlnj-c
833      src/tools/TraceDebugProf -> trace-debug-profile
834    
835    In addition, there is also a new
836    
837      ml-lpt
838    
839    directory containing two new program generator tools: ml-ulex and
840    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
841    LL(k) parser generator). These tools are currently "beta-quality"
842    
843    The latest versios of the sources can now be obtained anonymously
844    via subversion.  For this, it is useful to first check out
845    
846       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
847    
848    and put the resulting directory on your shell's PATH.  This provides
849    access to three shell scripts: checkout-all.sh, stat-all.sh,
850    and refresh-all.sh.
851    
852    To create a freshly checked-out copy of the sources, do
853    
854       checkout-all.sh [dir]
855    
856    where dir is the optional SML/NJ root directory (default is ".").
857    
858    This creates the above directory layout.  Each subdirectory of
859    the root is under individual subversion control.  The stat-all.sh
860    and refresh-al.sh scripts apply "svn stat" or "svn update" to
861    each of these subtrees.
862

865    Date: 2006/11/02 12:20:00 CST
866    Description:
867    
868    Reorganized directory layout.
869    
870    This is a temporary solution, more reorganization is to come.
871    
872    The basic idea is to have a number of toplevel trees, each corresponding
873    to a well-defined part of the overall system.  Each part can be
874    maintained individually, even in separate source repositories,
875    although currently we still serve everything out of the main
876    smlnj-gforge tree.
877    
878    Installer and and scripts have been updated to reflect the new
879    layout.  The installer (base/src/system/smlnj/installer) is now
880    "scriptable" to avoid burning too much knowledge about the
881    layout into SML source code.  The main script used by the installer
882    is in config/actions.
883    
884    The main change is that many of the subdirectories of what used to
885    be known as "src" have moved to the toplevel.  The "src" directory
886    itself has moved down into a subtree called "base".  (We may eventually
887    get rid of the extra level of indirection represented by "src".)
888    
889    The layout is now as follows:
890    
891      toplevel tree name | default repository
892                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
893      -------------------+----------------------------------------------------
894      config             | $gf/config/trunk
895                         |
896      base               | $gf/sml/trunk
897                         |
898      smlnj-lib          | $gf/smlnj-lib/trunk
899      MLRISC             | $gf/MLRISC/trunk
900                         |
901      ml-yacc            | $gf/ml-yacc/trunk
902      ml-lex             | $gf/ml-lex/trunk
903      ml-burg            | $gf/ml-burg/trunk
904      lexgen             | $gf/lexgen/trunk
905      heap2asm           | $gf/heap2asm/trunk
906                         |
907      cml                | $gf/cml/trunk
908      eXene              | $gf/eXene/trunk
909      ckit               | $gf/ckit/trunk
910      nlffi              | $gf/nlffi/trunk
911                         |
912      smlnj-c            | $gf/smlnj-c/trunk
913    
914    In $gf/admin there are a few useful shell scripts for checking out
915    and maintaining the entire collection of trees:
916    
917       admin/checkout-all.sh [dir]
918          -- optionally creates dir and checks out all trees from their
919             default repositories; if dir is missing, checkout into .
920       admin/refresh-all.sh [dir]
921          -- looks at all trees (from the above list) in dir (default: .)
922             and runs "svn update" if the tree exists and is under
923             subversion control;
924             non-existing or non-subversion trees are skipped
925       admin/stat-all.sh [dir]
926          -- like refresh-all.sh, but runs "svn stat" instead

941    Description:
942    
943    New working version (110.59).  NEW BOOTFILES!
944    
945    I am freezing 110.59.  Changes other than the version-number increase:
946    
947      eXene:
948    
949         * committed changes to eXene from Alley Stoughton:
950             "fixed bugs in X authorization and resource handling, as well
951              as in the pile and viewport widgets"
952    
953      Runtime:
954        * fixed linking problem with NetBSD 3.x.
955    
956      Lexgen:
957        * lexgen tool handles non-ascii characters in 7-bit mode the same
958          way that ml-lex does
959    
960        * lexgen propagates exceptions the same way that ml-lex does
961    
962      CML:
963        * Fixed a bug in the SyncVar polling functions (iGetPoll,
964          mTakePoll, and mGetPoll) that could lead to livelock.

970    Description:
971    
972    Implemented ml-makedepend (i.e., CM.sources) in a better (more robust)
973    way.  This should hopefully fix the ml-makedepend problem permanently.

980    
981    Fixed long-standing bug with ml-makedepend where it would output a
982    spurious dependency to a non-existing file.  (This is a simple fix.
983    It might need further looking into.)

1075    (This is a temporary solution which relies on the fact that the

1077    intel mac from generic x86 unix code and make separate sets of binaries.)

1106    Description:
1107    
1108    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
1109    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
1110    at the time when config/preloads is processed, the library has to
1111    be referred to by another name.  In 110.57 this would be
1112    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
1113    to be valid as well.)
1114    
1115    Thanks to Todd Wilson (Fresno) for alerting me to this issue.

1168    Tag: blume-22051115-versiontool
1169    Description:
1170    
1171    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
1172    file gets loaded as a tool -- by the equivalent of CM.make during the
1173    run of CMB.make.  Thus, CMB's path configuration is meaningless for
1174    it.  Instead, it has the status of "user code", so it should use
1175    $/basis.cm to refer to the Basis library.  (At least that's true for
1176    the purpose of bootstrapping the previous change.  In the future it
1177    might make sense to have versiontool.cm refer to
1178    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1179    compiler itself uses.)
1180    
1181    Also patched src/system/testml to have it activate those extra anchor
1182    bindings in config/extrapathconfig.

1187    Tag: blume-22051115-libraries
1188    Description:
1189    
1190    This change affects the way the following libraries are tied into
1191    the system:
1192    
1193       $/basis.cm
1194       $/smlnj-lib.cm
1195       $/pp-lib.cm
1196       $/controls-lib.cm
1197       $/html-lib.cm
1198       $/ml-yacc-lib.cm
1199    
1200    These libraries are now internally (as seen from the source code
1201    of the implementation itself) known by the following names:
1202    
1203       $smlnj/basis/basis.cm
1204       $smlnj/smlnj-lib/smlnj-lib.cm
1205       $smlnj/smlnj-lib/pp-lib.cm
1206       $smlnj/smlnj-lib/controls-lib.cm
1207       $smlnj/smlnj-lib/html-lib.cm
1208       $smlnj/ml-yacc/ml-yacc-lib.cm
1209    
1210    This makes it possible to work with code that requires different
1211    versions of these libraries, and which refers to these libraries using
1212    their "default" names (i.e., the first set of names above).  In other
1213    words, one can un-define or re-define those default names without
1214    compromising the proper functioning of the compiler itself.
1215    
1216    A similar procedure had already been performed for several of the
1217    MLRISC libraries that are linked into the compiler.  I did some
1218    cleanup on this code.
1219    
1220    A new file in the config directory (named extrapathconfig) is
1221    responsible for setting up path anchors that the compiler itself does
1222    not need, but that are typically required by user code.

1401    Tag: blume-20050516-redump-heap
1402    Description:
1403    
1404    Added mechanism for re-creating a heap file for the interactive system
1405    after configuration variables have been changed.
1406    
1407       CM.redump_heap : string -> unit
1408    
1409    This is much like SMLofNJ.exportML, but starting from the resulting
1410    heap does not return to the caller of CM.redump_heap but
1411    restarts the interactive system from scratch.  The original call of
1412    CM.redump_heap does not return but ends the interactive session.
1413    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1414    
1415    Internally, redump_heap winds the dynamic execution context back to
1416    the point where the original heap image was created and re-executes
1417    the heap image generation code in the boot code.

1533    Tag: blume-20050114-heap2exec
1534    Description:
1535    
1536    Implemented new (but still experimental) heap2exec facility.  This is
1537    tested under Mac OS X and should work under Linux (will test shortly).
1538    It will probably also work on the Sparc (will test some time later).
1539    
1540      - removed old "HACKED_STANDALONE" hack from runtime
1541    
1542    To be able to test this, uncomment the request for "heap2asm" in
1543    config/targets prior to installation.  (Notice that this is different
1544    from "heap2exec" mentioned below.  Not a typo.)
1545    
1546    To perform an actual test, run the command
1547    
1548       $ bin/heap2exec heapfile execfile
1549    
1550    (You can put heap2exec on your shell's path.)
1551    
1552    For example, run
1553    
1554      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1555    
1556    This will create a standalone executable called "mly" which you can
1557    then invoke directly as a command.

1702    Tag: blume-20041124-position
1703    Description:
1704    
1705    The compiler can now be compiled in a mode that makes structure Position
1706    equal to Int64.  The default, however, is unchanged (Position = Int31)
1707    for the time being.
1708    
1709    To enable 64-bit positions, use the following procedure:
1710    
1711    1. Start sml
1712    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1713    3. Type
1714          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1715    4. Run CMB.make() as usual.
1716    
1717    This is barely tested.  The only test so far was a little SML program
1718    counting the number of characters in an 8-gigabyte file by
1719    reading it character-by-character.  That test was successful.
1720    
1721    In support of 64-bit positions, a number of new functions have been
1722    added to the runtime system.

1767    
1768    - In a previous commit, fixed a minor issue with how polyequal is being
1769      translated.  In particular, the code now "looks through" abstractions.
1770      This results in slightly fewer polyEqual warnings and hopefully slightly
1771      more efficient code.  Important examples for where this matters are
1772      the new int64 and word64 types.

1806    at the moment.
1807    
1808    Making Word64 official would mean that LargeWord becomes Word64.  But
1809    this requires extreme care because most word-word conversions have to
1810    go through LargeWord, so making a mistake means loss of efficiency or
1811    worse.  Eventually there will be a solution similar to (but actually
1812    simpler than) what I did with IntInf.

1842    Also:
1843    
1844      - Changend config/srcarchiveurl from a file just
1845        containing the URL string into a file containing
1846        shell script code.  The code has access to the $VERSION variable.
1847      - Made corresponding changes to config/install.sh and config/unpack.
1848      - Default contents of config/srcarchiveurl uses $VERSION and
1849        normally does not have to be edited to reflect a version change.
1850    
1851      (As a result, a version change can be done by just editing
1852       config/version, the rest is now automatic.)

1892    Tag: blume-20041020-standalone-backtrace
1893    Description:
1894    
1895    Added a mechanism for getting back-trace information from standalone
1896    programs.  Here is how it works:
1897    
1898       1. The part of the program from which you want to get backtrace
1899          information (usually the whole program) should be wrapped with
1900          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
1901          main program could be modified from something like
1902    
1903             fun main (pgm, args) = ...
1904    
1905         to
1906    
1907            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1908    
1909       2. To be able to access BackTrace.monitor, you have to add
1910          library $smlnj-tdp/plugins.cm to the .cm file that contains your
1911          main function.
1912    
1913       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1914          CM might have created in the past for your project).
1915    
1916       4. Build the system using this command line:
1917    
1918             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1919                      myprog.cm MyProg.main myprog
1920    
1921          instead of the usual
1922    
1923             ml-build myprog.cm MyProg.main myprog
1924    
1925    I changed a library name:
1926    
1927       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1928    
1929    New libraries:
1930    
1931       $smlnj-tdp/back-trace.cm
1932          -- when loaded causes the back-trace plugin to be installed
1933       $smlnj-tdp/coverage.cm
1934          -- when loaded causes the coverage plugin to be installed

1950    Description:
1951    
1952    * Test coverage tool added!
1953    * Further reorganization of tracing-, debugging-, and profiling support:
1954    
1955        - moved original BTImp -- now called BackTrace -- into a separate
1956          library called $/trace-debug-profile.cm
1957        - eliminated all mentions of BTrace from SMLofNJ.Internals
1958        - only the instrumentation mechanism is now left in the compiler proper
1959        - BackTrace module is a plugin which is NOT plugged in by default
1960        - Coverage module is another such plugin
1961    
1962    To get the benefits of any of these plugin modules, the code in
1963    question must be compiled with tdp instrumentation turned on.  This
1964    can be done by setting SMLofNJ.Internals.TDP.mode to true.
1965    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1966    
1967    Plugins are selected at link time.  (Pre-compiled instrumented code
1968    can be re-loaded with different plugins in effect.)  When an
1969    instrumented module is linked, whatever plugins are at that time
1970    enabled will come into effect for that module.
1971    
1972    To enable the back-trace plugin, load library $/trace-debug-profile.cm
1973    and invoke BackTrace.install() (e.g., from the interactive prompt).
1974    To enable the coverage plugin, load the same library and invoke
1975    Coverage.install().
1976    
1977    Back-traces are generated automatically on uncaught exceptions and
1978    when the code in question explicitly invokes BackTrace.trigger().
1979    
1980    Coverage (and execution frequency-) information must be queried
1981    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2006    
2007    The control flag controlling whether instrumentation is on or off is now

2010     sml -Cinstrument.btrace-mode=true

2035    
2036    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
2037    is supposed to accept a tool argument called "source", but this did
2038    not work because of the clash with the keyword.

2086    
2087    * At the same time, structure CompilerVersion is now known as
2088      structure SMLNJVersion.
2089    
2090    * Arranged for the version tool to NOT kick in when rebuilding the system
2091      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
2092      Also, loading the versiontool does not work when rebuilding the system
2093      because CM is not properly initialized at that time.

2099    Description:
2100    
2101    Implemented some CM magic to have
2102        file src/compiler/TopLevel/main/version.sml
2103    generated automagically.
2104    The version is taken from two files: config/version and config/release.
2105    The first is expected to contain a two-part version number such as 110.49.
2106    The second should contain a single number, but it may be missing.
2107    
2108    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2109    time the version tool is loaded (which is the first time you say CMB.make),
2110    then the tool will increment the value stored in config/release every
2111    time CMB.make is invoked.
2112    
2113    The binfile format is now insensitive to anything beyond the first
2114    two components of a version number, so bumping the release does not render
2115    binfiles incompatible.  Auto-bumping can be used to keep track of versions
2116    during development without invalidating existing binfiles.
2117    
2118    In any case, every CMB.make updates the date information in version.sml.
2119    (This is the date that is printed in the banner.)

2132    Tag: blume-20040927-controls
2133    Description:
2134    
2135    Added two pieces of functionality to the Controls interface:
2136    
2137    1.   val save'restore: 'a control -> unit -> unit
2138    
2139       grabs the current value of the control in stage 1 and restores it
2140       in stage 2.
2141    
2142    2.   val set' : 'a control * 'a -> unit -> unit
2143    
2144       stores the given value into the control in stage 2 (i.e., delayed)
2145       but does all error checking in stage 1.
2146       (This is for string controls that need to do parse their argument --
2147        something that might fail.  In some cases, notably in CM, one
2148        already knows the intended argument but wants to delay the actual
2149        assignment until a time when error recovery would be more difficult.)
2150    
2151    Changed the handling of controls in tool arguments to classes "sml" and
2152    "lazysml":
2153       - use Controls.save'restore as a more robust way of restoring the
2154         old value (in particular: without having to re-parse the string)
2155       - use controls to handle the "overload" keyword in the init group
2156         (I believe this change actually fixes a long-standing obscure bug.)

2161    Tag: blume-20040927-lazysml
2162    Description:
2163    
2164    Added a new tool class called "lazysml" to CM's tool chest.  The only
2165    difference to "sml" is that compilation is done with Control.lazysml
2166    set to true.  A source of class "lazysml" is automatically recognized
2167    by a file name suffix of ".lml".
2168    
2169    In addition to the above feature, the original class "sml" now also
2170    supports a tool argument "lazy" which has the same effect.  As a
2171    result, the following three lines are equivalent:
2172    
2173        foo.sml : lazysml
2174        foo.sml : sml (lazy)
2175        foo.sml (lazy)
2176    
2177    The setting goes into effect both during parsing and during
2178    compilation.  The original setting is restored right after parsing and
2179    after compilation, respectively.
2180    
2181    In addition to all the above, there is also a general mechanism to set
2182    ANY of the "controls" that are available at the command line via
2183    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
2184    apply as well. (In fact, "lazy" is implemented as a special case of
2185    the general mechanism.)
2186    
2187    The .cm file syntax uses a new keyword tool argument called "with".
2188    There are several ways of indicating the desired settings:
2189    
2190        foo.sml (with:parser.quotations=true)
2191        foo.sml (with:(name:parser.quotations value:true))
2192        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2193        foo.sml (with:(name1=value1 name2=value2 ...))
2194        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2195    
2196        etc.
2197    
2198    Another possible abbreviation is to leave out the =v or value:v part
2199    if the name refers to a boolean control (in which case the value is
2200    taken to be true).  Thus, one could get lazy sml also by saying:
2201    
2202        foo.sml (with:parser.lazy-keyword=true)
2203        foo.sml (with:parser.lazy-keyword)
2204        foo.sml (with:(name:parser.lazy-keyword value:true))
2205        foo.sml (with:(name:parser.lazy-keyword))

2557    Description:
2558    
2559    Changed the interface of structures Timer and Unix to match the most
2560    recent Basis spec.
2561    
2562    In the case of Unix there still seems to be an open/weird issue:
2563    
2564       The {text,bin}{In,Out}streamOf functions are supposed to create
2565       fresh streams whenever they are called -- as opposed to have them
2566       return the same stream every time.  This design is supposed to
2567       prevent space leaks caused by proc values hanging on to streams.
2568    
2569       The reap function, on the other hand, is supposed to close the
2570       streams.  This cannot be done without having a handle on the
2571       stream in proc after all...
2572    
2573    I took the liberty to implement the following stopgap solution:
2574    
2575      The proc value hangs on to the most recently created stream(s).
2576      Reap closes those.  If either or both of the two streams hadn't
2577      been created at all yet, then reap will close the corresponding
2578      file descriptors directly.
2579    
2580    PS: I don't understand the original space leak argument anymore.  If
2581    a proc hangs on to the imperative stream, then I/O operations on those
2582    will advance the state of the cached stream and avoid the space leak.

2596    Description:
2597    
2598    CM now ignores (but still accepts) the "owner" information in group
2599    descriptions.  The owner of a group is its next enclosing
2600    library. Each group must have a unique owner.  (There is a virtual
2601    "toplevel" library that owns groups which are not nested within a real
2602    library.)  Previously, each group had to explicitly declare its owner,
2603    and CM would check that such a declaration is correct.  The new scheme
2604    is to have CM check that for each group there is precisely one owning
2605    library.
2606    
2607    The advantage of the new scheme is that the programmer no longer needs
2608    to maintain the somewhat annoying owner information.  The downside is
2609    that CM cannot enforce the ownership rule across multiple runs of
2610    CM.make.  Fortunately, enclosing the same group in two different
2611    libraries A and B which are not part of the same program does not
2612    cause real problems.

2631    Description:
2632    
2633    Arranged for ml-build to clean up after itself a little bit better.
2634    The script generates a temporary SML source file and compiles it using
2635    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
2636    gets rid of those at the end, so they don't accumulate under .cm.
2637    
2638    This required a minor change to install.sh because the name of the
2639    metadata directory (default: .cm) is actually configurable at
2640    installation time.

2661    (I have not tested this patch under win32 yet.)
2662    
2663    Here is David's e-mail:
2664    
2665    Hi,
2666    
2667    Attached to this email you find a diff against sml/nj 110.45
2668    that will enable socket support under Windows.
2669    
2670    To apply the patch (using unix or cygwin)
2671    1) gunzip runtime.diff.gz
2672    2) "cd" into "src/runtime" in the source tree of a fresh
2673       110.45 installation.
2674    3) patch -p 1 < [your/path/to]runtime.diff
2675    
2676    The code compiles fine but has NOT yet been extensively tested.
2677    I only ran a few tests for basic socket client functionality
2678    (which worked fine).  Especially the functions that use ioctl
2679    are not tested at all and might not work (see below).
2680    
2681    I implemented this since we want to move to a newer version of sml/nj
2682    but need socket support in order to use it.  This is the first time I
2683    even had a look at the sml/nj source,  so please review my changes
2684    before making this part of the distribution!  Here are a few issues
2685    that I think might be better for someone to solve who is more
2686    familiar with the sml/nj source (and socket programming):
2687    
2688    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2689      exception since I could not figure out what the windows equivalent
2690      of these functions is
2691    
2692    - In sockets-osdep.h there are a some #include statements that are
2693      only used in a few files that include sockets-osdep.h
2694    
2695    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2696      does not process its return value since I don't know how to
2697      report an error upwards.
2698    
2699    - It would probably be good to have a call to WSACleanup() when
2700      the library is unloaded (if there is such a possibility).
2701      Otherwise I think Windows will take care of this automatically
2702      when the process finishes.
2703    
2704    - I used ioctlsocket() as a replacement for ioctl() but I have
2705      no idea if that is actually the proper replacement on Windows.
2706    
2707    - All these issues are marked in the code by "FIXME" comments.
2708    
2709    We use sml/nj extensively in our products and are quite happy
2710    with it.  I hope this contribution will help you.
2711    
2712    Keep up the good work!
2713

2747    Description:
2748    
2749    The installer now honors the "src-smlnj" target again, although its meaning
2750    has changed from "all sources required for the compiler" to "all sources
2751    the installer knows about".  In other words, if you enable "src-smlnj"
2752    in the "targets" file, then the installer will pull in sources for
2753    everything.  (Notice that this refers to source code only.  Compiled
2754    code is still only installed for modules that were requested explicitly
2755    or which are required for other modules that were requested explicitly.)

2789    Description:
2790    
2791    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
2792    of SML/NJ.  The problem is that
2793    
2794       lib = dlopen(NULL, ...)
2795       f   = dlsym(lib, "malloc");
2796    
2797    does not work on Windows unless we explicitly export symbols
2798    such as 'malloc' during linking.  We fixed this by explicitly
2799    exporting the required symbols with the magic gcc incantation:
2800    
2801        -Wl,--export-all cygwin.def
2802    
2803    where cygwin.def is a file containing all the symbols that
2804    we wish to export.
2805    
2806    I suspect this is a Windows problem and we'll have to
2807    do the same (somehow with windows compilers) when
2808    we build the native win32 version with the system
2809    calls LoadLibrary/GetProcAddress.

2878    
2879    Eliminated the "dont_move_libraries" directive in config/targets.
2880    (The mechanism was broken and could not be fixed easily.  Moreover,
2881    there does not seem to be any reason not to move all libraries into
2882    lib during installation.  I originally implemented this directive as a
2883    backward-compatibility feature when I first introduced the new CM.
2884    Now that things have been stable for a long time and going back to the
2885    old CM is not an option, there is no reason to keep it around.)

2934    Tag: blume-20030926-ppautoload
2935    Description:
2936    
2937    I modified the read-eval-print loop so that the autoloader gets
2938    invoked whenever the prettyprinter tries to look up a symbol that
2939    is not currently defined in the toplevel environment but which
2940    appears in CM's autoload registry.  As a result, we see far fewer of
2941    those ?.Foo.Bar.xxx names in the prettyprinter's output.
2942    
2943    In addition to this I tried to clean up some pieces of the Basis
2944    implementation (e.g., Socket, Word8Array) in order to prevent other
2945    instances of these ?.Foo.Bar.xxx names from being printed.
2946    
2947    The mechanism that picks names for types still needs some work, though.
2948    (Right now it seems that if there is a type A.t which is defined to
2949    be B.u, but B is unavailable at toplevel, then A.t gets printed as
2950    "?.B.u" although the perhaps more sensible solution would be to use
2951    "A.t" in this case.  In other words, the prettyprinter should follow
2952    a chain of DEFtycs not farther than there are corresponding toplevel
2953    names in the current environment.)

2959    Description:
2960    
2961    Another installer tweak:  All the ML code for the installer is now
2962    compiled during CMB.make and put into a little library called
2963    $smlnj/installer.cm.  The installation then simply invokes
2964    
2965       sml -m $smlnj/installer.cm
2966    
2967    and everything happens automagically.
2968    
2969    Win32:  ML code senses value of environment variable SMLNJ_HOME.
2970    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
2971            and BINDIR.
2972    
2973    The new scheme guarantees that the ML code responsible for the installation
2974    is in sync with the APIs of the main system.  Also, the installer is
2975    somewhat faster because the installer script is precompiled.

2986    implementations of non-blocking operations from CML's Socket
2987    structure.

2992    Tag: blume-20030924-sockets
2993    Description:
2994    
2995    1. Fixed SOCKET API and implementation to match Basis spec.
2996       This required changing the internal representation of sockets to one
2997       that remembers (for each socket file descriptor) whether it is currently
2998       blocking or non-blocking.  This state is maintained lazily (i.e., a system
2999       call is made only if the state actually needs to change).
3000    
3001    2. OS-specific details of sockets were moved into separate files, thus
3002       making it possible to unify the bulk of the socket implementations
3003       between Unix and Win32.
3004    
3005    3. CML's socket API changed accordingly.
3006       (Note that we need to remove non-blocking functions from this API
3007       since they are redundant in the case of CML!)
3008    
3009    4. CML's socket implementation now makes use of non-blocking functions
3010       provided by Basis, thus removing all OS-dependent code from this part
3011       of CML.
3012    
3013    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

3061    
3062    3. Improved Real.{from,to}LargeInt by avoiding needless calculations.

3096    
3097    Minor bugfix in config/libinstall (set anchor with path to
3098    standalone tool after installing it, otherwise libraries that
3099    need ml-lex or ml-yacc won't compile the first time the installer
3100    runs).

3126    Description:
3127    
3128    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3129    Modified config/install.bat to take advantage of it.  Also modified
3130    config/install.sh (and called it config/new-install.sh) to take advantage
3131    of it on Unix systems.  (The SML code is (supposed to be) platform-
3132    independent.)
3133    
3134    The installer can now install everything under Win32
3135    as well as under *nix as long as it compiles.
3136    
3137    Other changes:
3138    
3139      - made CML compile again under Win32
3140      - made eXene compile under Win32 (by providing a fake structure UnixSock
3141        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3142      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3143        same as type int;  under Win32 it isn't
3144      - fixed some slice-related problems in the win32-specific parts of CML
3145      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3146        (under Win32, the volume name is case-insensitive, and the
3147        OS.Path code compares volume names for equality)

3153    Description:
3154    
3155    Made Win32 version of OS.FileSys.fullPath return current directory
3156    when given an empty string.  This is what the spec says, and incidentally,
3157    CM depends on it.  (CM otherwise goes into an infinite loop in certain
3158    cases when presented with the name of a non-existing .cm file.)

3164    Description:
3165    
3166      1. Changed interface to vectors and arrays in Basis to match
3167         (draft) Basis spec.
3168      2. Added signatures and implementations of slices according to
3169         Basis spec.
3170      3. Edited source code throughout the system to make it compile again
3171         under 1. and 2.  (In some cases code had to be added to have it
3172         match the new signatures.)
3173      4. MLRISC should be backward-compatible: the copies of the originals
3174         of files that needed to change under 3. were retained, the .cm files
3175         check the compiler version number and use old versions when
3176         appropriate.
3177      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3178         dirstream -> string option (in accordance with Basis spec).
3179      6. When generating code that counts lines, ml-lex used function
3180         CharVector.foldli, taking advantage of its old interface.
3181         This has been replaced with the corresponding code from
3182         CharVectorSlice.  (html-lex must be re-lexed!)
3183      7. BitArray in smlnj-lib/Util has been extended/modified to match the
3184         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
3185      8. Removed temporary additions (fromInternal, toInternal) from the
3186         (now obsolete) IntInf in smlnj-lib/Util.
3187      9. Cleaned up structure Byte.
3188     10. Added localOffset, scan, and fromString to Date (according to spec).
3189         Cleaned/corrected implementation of Date.
3190         (Still need to check for correctness; implement better canonicalizeDate.)
3191     11. Added "scan" to signature IEEE_REAL.
3192     12. Some improvements to IntInf [in particular: efficiency-hack for
3193         mod and rem when second operand is 2 (for parity checks).]
3194     13. Changed representation of type Time.time, using a single IntInf.int
3195         value counting microseconds.  This considerably simplified the
3196         implementation of structure Time.  We now support negative time
3197         values; scan and fromString handle signs.
3198     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3199         ArraySlice).

3205    Description:
3206    
3207    This is a major update which comes with a version number bump
3208    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3209    and an implementation of IntInf in the Basis.
3210    
3211    There are a fairly large number of related changes and updates throughout
3212    the system:
3213    
3214    Basis:
3215            - Implemented IntInf.
3216            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3217            - Added some missing Real64 operations, most notably Real.toLargeInt.
3218            - Added FixedInt as a synonym for Int32.
3219    
3220    compiler:
3221            * Added support for a built-in intinf type.
3222              - literals
3223              - pattern matching
3224              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3225              - overloading on literals and operations
3226    
3227            This required adding a primitive type intinf, some additional
3228            primops, and implementations for several non-trivial intinf
3229            operations in Core.  (The intinf type is completely abstract
3230            to the compiler; all operations get delegated back to the Core.)
3231    
3232            * Intinf equality is handled by polyequal.  However, the compiler
3233            does not print its usual warning in this case (since polyequal
3234            is the right thing to do there).
3235    
3236            * Improved the organization of structure InlineT.
3237    
3238            * A word about conversion primops:
3239            If conversions involving intinf do not cancel out during
3240            CPS contract, then the compiler must insert calls to Core functions.
3241            Since all core access must be resolved already during the FLINT
3242            translate phase, it would be too late a the time of CPS contract
3243            to add new Core calls.  For this reason, conversion primops
3244            for intinf carry two arguments:  1. the numeric argument that
3245            they are supposed to convert, and 2. the Core function that
3246            can help with this conversion if necessary.  If CPS contract
3247            eliminates a primop, then the associated Core function becomes
3248            dead and goes away.  Intinf conversion primops that do not get
3249            eliminated by CPS contract get rewritten into calls of their
3250            core functions by a separate, new phase.
3251    
3252    interactive system:
3253            - Control.Print.intinfDepth controls max length of intinf constants
3254            being printed. (Analogous to Control.Print.stringDepth.)
3255            - Cleanup in printutil and pputil: got rid of unused stuff and
3256            duplicates; replaced some of the code with code that makes better
3257            use of library functionality.
3258    
3259    CM:
3260            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3261            are no longer silent.
3262    
3263    CKIT:
3264            Fixed mismatched uses of Int32 and LargeInt.  I always decided
3265            in favor of LargeInt -- which is now the same as IntInf.
3266            CKIT-knowledgable people should check whether this is what's
3267            intended and otherwise change things back to using Int32 or
3268            FixedInt.
3269    
3270    Throughout the code:
3271            Started using IntInf.int literals and built-in operations
3272            (e.g., comparison with 0) where this seems appropriate.

3279    Description:
3280    
3281    Merging changes from the mcz-branch development branch into trunk.
3282    These changes involve replacement of the emulated old prettyprinter
3283    interface with direct use of the SML/NJ Lib PP library, and fixing
3284    of a couple of bugs (895, 1186) relating to error messages.  A new
3285    prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
3286    has been added.

3293    
3294    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
3295    
3296        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3297    
3298    This patch restores SML/NJ's ability to run under win32.  There are a
3299    number of changes, including fixes for several bugs that had gone
3300    unnoticed until now:
3301    
3302      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3303        trying to run the win32 version from within cygwin.)
3304    
3305      - There are a number of simple .bat scripts that substitute for their
3306        corresponding Unix shell-scripts.  (See below.)
3307    
3308      - The internals of ml-build have been modified slightly.  The main
3309        difference is that instead of calling ".link-sml" (or link-sml.bat)
3310        using OS.Process.system, the ML process delegates this task back
3311        to the script.  Otherwise problems arise in mixed environments such
3312        as Cygwin where scripts look and work like Unix scripts, but
3313        where OS.Process.system cannot run them.
3314    
3315      - In CM, the srcpath pickler used native pathname syntax -- which
3316        is incorrect in the case of cross-compilation.  The new pickle format
3317        is independent of platform-specific naming conventions.
