174    Description:
175    
176    The GAS output now favors p2align over align, since the
177    former is guaranteed to be consistent over multiple architectures
178    and the latter is not.

256    
257    - Aaron: fixed a number of bugs in ml-ulex.
258    - Matthias:
259       - added CM control "cm.force-tools"; this is false by default;
260         when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
261         will be forced to run regardless of whether or not their targets
262         are up-to-date
263       - changed installer code so that config/install.sh will re-build
264         heap images for all tools even if those heap images already existed

270    
271    After Aaron Turon's bug fix for ml-ulex (handling the ^ character
272    in legacy mode), re-ran the lexer generator on all lex input files
273    and committed the results.
274    
275    This should fix the problem with ckit and nlffi that was reported
276    by Vesa A. Norrman.

291    
292    3rd merge of base from primop-branch-3 into the trunk.
293    Additional bug fixes included:
294    
295     * Timer.cpu_timer, etc. type printing corrected (by making
296         Timer have opaque sig constraint in basis/Implementation/timer.sml)

303    Description:
304    
305    Fixed some bugs in new Div code in FLINT/trans/translate.sml.
306    
307    Also, changed the handling of "no core access":  When translate.sml
308    needs access to a core exception at a time when the core has not
309    been set up yet (this only happens when compiling system/smlnj/init/*),
310    then don't bother generating the corresponding tests.
311    
312    The old scheme was to generate a bogus value to be used in place of
313    the exception.  Unfortunately, that confuses the plambda type checker.
314    Moreover, it does not do any good, because at runtime we don't expect
315    such an exception to be ever raised.  (The code in system/smlnj/init/*
316    has to be written very carefully with this in mind!)

329    
330    FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
331    with an explicit test for zero division.  This should fixes several
332    regressions and makes it possible for downstream optimization phases
333    to treat these operations as "pure" when they are applied to unsigned
334    operands.

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

356    Date: 2007/05/23 22:30:00 CDT
357    Description:
358    
359    CMB (and CM) now automatically defines the CM "preprocessor" symbol
360    NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
361    
362      (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
363       CM_SLAVE_MODE is defined in attached slaves while running CM.make
364       or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
365       while running CMB.make.  The point is that the single symbol
366       NO_PLUGINS is definde in all three cases.)
367    
368    I changed the three locations within the sources that get compiled
369    during CMB.make where ml-yacc or ml-lex input is processed: When
370    NO_PLUGINS defined, then the use of the mlyacc and mllex tools
371    is bypassed.
372    
373    When bootstrapping new versions of the compiler, there can be
374    situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
375    are not available or otherwise not operational.  In this case one can
376    manually define the NO_PLUGINS symbol prior to running CMB.make().  To
377    do so, the following command should be issued at the interactive
378    prompt:
379    
380       #set (CMB.symval "NO_PLUGINS") (SOME 1);
381    
382    A CMB.make with NO_PLUGINS defined relies on the existence of the
383    files that normally would be generated by ml-yacc and ml-lex.
384    (Copies of these files are in the repository.)

400    Description:
401    
402    Changed the installation mechanism for CM tool plugins.  These are
403    just libaries and now get installed like ordinary libaries.
404    
405    There are now a number of new installation targets that give some
406    fine-grain control over what classes and suffixes are known, and what
407    they will map to.
408    See config/targets for details.
409    
410    The code that caused plugin installation as part of running a
411    tool's "build" script has been removed.  (The build script is for
412    building, not for installing.)

418    
419    Added a boolean control named cm.tolerate-tool-failures (env. variable
420    name: CM_TOLERATE_TOOL_FAILURES).  The default is false and makes
421    CM fail if a shell tool reports a non-success exit status.  If
422    the control is set to true, then CM will press on after tool failures
423    in the event that the target files exist (even though they are
424    considered outdated).  Turning the control to true can be useful for
425    bootstrapping.

430    Description:
431    
432    Merge of ml-lpt revisions for 110.64.
433    
434    The name of several ml-lpt-lib modules has changed:
435      Repair        => AntlrRepair
436      StreamPos     => AntlrStreamPos
437      ErrHandlerFn  => AntlrErrHandler
438      EBNF          => AntlrEBNF
439    
440    The ml-antlr specification format has changed: declarations such as
441    %tokens and nonterminal definitions can occur *multiple* times in the
442    same specification.  The semantics are such that each new declaration
443    extends the previous ones.  This does not apply to %start or %name,
444    of course.
445    
446    Importing a grammar via %import now includes *all* declarations in from
447    the imported grammar, except for %name, %entry, and %start.  Tokens
448    and nonterminals can be dropped using the new %dropping clause of the
449    %import directive; the separate %drop and %extend have been removed.
450    
451    We now allow optional type annotations on nonterminals, using the %nonterms
452    directive as in ml-yacc.
453    
454    The refcell construct is now implemented using SML's regular reference
455    cells, so the :== and !! notation has been deprecated.
456    
457    The ml-antlr tool now does much more checking of specifications, and
458    its error messages have been greatly improved.  Error repair for
459    generated parsers has been completely rewritten, and is now both
460    much faster and more accurate.
461    
462    ml-ulex is now more lenient with escape codes (non-SML-standard
463    escape codes are now interpreted literally, so e.g. \| denotes "|").
464    Also, character classes may now include a "-" character at the beginning
465    as is standard in most other regexp tools.
466    
467    All of these changes are documented in the user guide, which has
468    been updated and improved with this merge.

485    
486    Preliminary commit of large ml-lpt revisions (more to come for 110.64).
487    The ml-antlr specification format has changed: declarations such as
488    %tokens and nonterminal definitions can occur *multiple* times in the
489    same specification.  The semantics are such that each new declaration
490    extends the previous ones.  Grammar extension constructs have also
491    changed.  We now allow type annotations on nonterminals.  Finally,
492    the refcell construct is now implemented using SML's regular reference
493    cells, so the :== and !! notation has been deprecated.  All of these
494    changes will appear in the 110.64 user guide for ml-lpt.
495    
496    The ml-antlr tool now does much more checking of specifications, and
497    its error messages have been greatly improved.  There has also been
498    some work on the error repair process for generated parsers, but this
499    will be further improved in 110.64.

622    for specifying calling conventions (see
623    http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
624    Initially, we plan to use this code to generate C calls for the AMD64.
625    
626    The staged allocation code base resides in MLRISC/staged-allocation,
627    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

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

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

708    Implemented library installer.  Moved CM plugin code for
709    ml-burg, ml-lex, and ml-yacc out of CM source tree and into

711    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
712    and ml-antlr.
713    
714    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
715    CM tools.  (It turns out to be too messy to do otherwise because
716    there is too much code that during installation relies on the presence
717    of these tools -- resulting in a tricky ordering problem.)

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

800    causes it to tolerate (with a warning) the situation where the shell
801    command fails (e.g., due to the shell command's non-existence)
802    as long as all target files exist.
803    
804    This makes it possible to, e.g., build ml-yacc from sources even if
805    svn checkout messed up the time stamps on files in such a way that
806    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
807    be needed to re-process yacc.grm, but obviously it might not yet be

849    
850    New working release (110.60).  NEW BOOTFILES!
851    
852    This is the first subversion-hosted release.  There are also changes
853    to the directory layout.  Here is a table:
854    
855    (All pathnames are relative to the SML/NJ "root" directory.)
856    
857      config -> config
858    
859      src/cm -> base/cm
860      src/compiler -> base/compiler
861      src/runtime -> base/runtime
862      src/system -> base/system
863    
864      src/cm/pgraph -> pgraph
865    
866      src/READMES -> base/READMES
867      src/$notefile -> base/NOTES/$notefile
868         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
869                           MACOSXINSTALL WININSTALL
870    
871      src/smlnj-lib -> smlnj-lib
872      src/MLRISC -> MLRISC
873      ckit -> ckit
874      src/cml -> cml
875      src/eXene -> eXene
876      src/heap2asm -> heap2asm
877      src/lexgen -> lexgen
878      src/ml-burg -> ml-burg
879      src/ml-lex -> ml-lex
880      src/ml-yacc -> ml-yacc
881      src/ml-nlffi-lib -> nlffi/lib
882      src/ml-nlffigen -> nlffi/gen
883      src/smlnj-c -> smlnj-c
884      src/tools/TraceDebugProf -> trace-debug-profile
885    
886    In addition, there is also a new
887    
888      ml-lpt
889    
890    directory containing two new program generator tools: ml-ulex and
891    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
892    LL(k) parser generator). These tools are currently "beta-quality"
893    
894    The latest versios of the sources can now be obtained anonymously
895    via subversion.  For this, it is useful to first check out
896    
897       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
898    
899    and put the resulting directory on your shell's PATH.  This provides
900    access to three shell scripts: checkout-all.sh, stat-all.sh,
901    and refresh-all.sh.
902    
903    To create a freshly checked-out copy of the sources, do
904    
905       checkout-all.sh [dir]
906    
907    where dir is the optional SML/NJ root directory (default is ".").
908    
909    This creates the above directory layout.  Each subdirectory of
910    the root is under individual subversion control.  The stat-all.sh
911    and refresh-al.sh scripts apply "svn stat" or "svn update" to
912    each of these subtrees.

916    Date: 2006/11/02 12:20:00 CST
917    Description:
918    
919    Reorganized directory layout.
920    
921    This is a temporary solution, more reorganization is to come.
922    
923    The basic idea is to have a number of toplevel trees, each corresponding
924    to a well-defined part of the overall system.  Each part can be
925    maintained individually, even in separate source repositories,
926    although currently we still serve everything out of the main
927    smlnj-gforge tree.
928    
929    Installer and and scripts have been updated to reflect the new
930    layout.  The installer (base/src/system/smlnj/installer) is now
931    "scriptable" to avoid burning too much knowledge about the
932    layout into SML source code.  The main script used by the installer
933    is in config/actions.
934    
935    The main change is that many of the subdirectories of what used to
936    be known as "src" have moved to the toplevel.  The "src" directory
937    itself has moved down into a subtree called "base".  (We may eventually
938    get rid of the extra level of indirection represented by "src".)
939    
940    The layout is now as follows:
941    
942      toplevel tree name | default repository

993    
994    New working version (110.59).  NEW BOOTFILES!
995    
996    I am freezing 110.59.  Changes other than the version-number increase:
997    
998      eXene:
999    
1000         * committed changes to eXene from Alley Stoughton:
1001             "fixed bugs in X authorization and resource handling, as well
1002              as in the pile and viewport widgets"
1003    
1004      Runtime:
1005        * fixed linking problem with NetBSD 3.x.
1006    
1007      Lexgen:
1008        * lexgen tool handles non-ascii characters in 7-bit mode the same
1009          way that ml-lex does
1010    
1011        * lexgen propagates exceptions the same way that ml-lex does
1012    
1013      CML:
1014        * Fixed a bug in the SyncVar polling functions (iGetPoll,
1015          mTakePoll, and mGetPoll) that could lead to livelock.

1157    Description:
1158    
1159    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
1160    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
1161    at the time when config/preloads is processed, the library has to
1162    be referred to by another name.  In 110.57 this would be
1163    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
1164    to be valid as well.)

1219    Tag: blume-22051115-versiontool
1220    Description:
1221    
1222    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
1223    file gets loaded as a tool -- by the equivalent of CM.make during the
1224    run of CMB.make.  Thus, CMB's path configuration is meaningless for
1225    it.  Instead, it has the status of "user code", so it should use
1226    $/basis.cm to refer to the Basis library.  (At least that's true for
1227    the purpose of bootstrapping the previous change.  In the future it
1228    might make sense to have versiontool.cm refer to
1229    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1230    compiler itself uses.)
1231    
1232    Also patched src/system/testml to have it activate those extra anchor
1233    bindings in config/extrapathconfig.

1238    Tag: blume-22051115-libraries
1239    Description:
1240    
1241    This change affects the way the following libraries are tied into
1242    the system:
1243    
1244       $/basis.cm
1245       $/smlnj-lib.cm
1246       $/pp-lib.cm
1247       $/controls-lib.cm
1248       $/html-lib.cm
1249       $/ml-yacc-lib.cm
1250    
1251    These libraries are now internally (as seen from the source code
1252    of the implementation itself) known by the following names:
1253    
1254       $smlnj/basis/basis.cm
1255       $smlnj/smlnj-lib/smlnj-lib.cm
1256       $smlnj/smlnj-lib/pp-lib.cm
1257       $smlnj/smlnj-lib/controls-lib.cm
1258       $smlnj/smlnj-lib/html-lib.cm
1259       $smlnj/ml-yacc/ml-yacc-lib.cm
1260    
1261    This makes it possible to work with code that requires different
1262    versions of these libraries, and which refers to these libraries using
1263    their "default" names (i.e., the first set of names above).  In other
1264    words, one can un-define or re-define those default names without
1265    compromising the proper functioning of the compiler itself.
1266    
1267    A similar procedure had already been performed for several of the
1268    MLRISC libraries that are linked into the compiler.  I did some
1269    cleanup on this code.
1270    
1271    A new file in the config directory (named extrapathconfig) is
1272    responsible for setting up path anchors that the compiler itself does
1273    not need, but that are typically required by user code.

1452    Tag: blume-20050516-redump-heap
1453    Description:
1454    
1455    Added mechanism for re-creating a heap file for the interactive system
1456    after configuration variables have been changed.
1457    
1458       CM.redump_heap : string -> unit
1459    
1460    This is much like SMLofNJ.exportML, but starting from the resulting
1461    heap does not return to the caller of CM.redump_heap but
1462    restarts the interactive system from scratch.  The original call of
1463    CM.redump_heap does not return but ends the interactive session.
1464    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1465    
1466    Internally, redump_heap winds the dynamic execution context back to
1467    the point where the original heap image was created and re-executes
1468    the heap image generation code in the boot code.

1584    Tag: blume-20050114-heap2exec
1585    Description:
1586    
1587    Implemented new (but still experimental) heap2exec facility.  This is
1588    tested under Mac OS X and should work under Linux (will test shortly).
1589    It will probably also work on the Sparc (will test some time later).
1590    
1591      - removed old "HACKED_STANDALONE" hack from runtime
1592    
1593    To be able to test this, uncomment the request for "heap2asm" in
1594    config/targets prior to installation.  (Notice that this is different
1595    from "heap2exec" mentioned below.  Not a typo.)
1596    
1597    To perform an actual test, run the command
1598    
1599       $ bin/heap2exec heapfile execfile
1600    
1601    (You can put heap2exec on your shell's path.)
1602    
1603    For example, run
1604    
1605      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1606    
1607    This will create a standalone executable called "mly" which you can
1608    then invoke directly as a command.

1634    data structure access seems to work.)
1635    
1636    * Fixed CM's incorrect assumption that the PPC is little-endian.
1637      (On the Mac, it is big-endian.  And that's currently our only
1638      PPC platform.)

1655    
1656        The Unix I/O library of SML/NJ on cygwin does not understand
1657    Windows style pathname, so problems arise when SMLNJ_HOME is set
1658    to a Windows style pathname.  _run-sml now converts SMLNJ_HOME
1659    to a POSIX pathname on cygwin.

1753    Tag: blume-20041124-position
1754    Description:
1755    
1756    The compiler can now be compiled in a mode that makes structure Position
1757    equal to Int64.  The default, however, is unchanged (Position = Int31)
1758    for the time being.
1759    
1760    To enable 64-bit positions, use the following procedure:
1761    
1762    1. Start sml
1763    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1764    3. Type
1765          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1766    4. Run CMB.make() as usual.
1767    
1768    This is barely tested.  The only test so far was a little SML program
1769    counting the number of characters in an 8-gigabyte file by
1770    reading it character-by-character.  That test was successful.
1771    
1772    In support of 64-bit positions, a number of new functions have been
1773    added to the runtime system.

1814    Description:
1815    
1816    - Stripped down the versiontool: It now only handles the version number.
1817      The date string is generated at bootstrap time (during makeml).
1818    
1819    - In a previous commit, fixed a minor issue with how polyequal is being
1820      translated.  In particular, the code now "looks through" abstractions.
1821      This results in slightly fewer polyEqual warnings and hopefully slightly
1822      more efficient code.  Important examples for where this matters are
1823      the new int64 and word64 types.

1838    Description:
1839    
1840    All the pieces of Word64 are now there, with the exception of the
1841    conversions from and to LargeWord. (Eventually these need to be identities,
1842    but for the time being they don't even make sense because LargeWord is
1843    32-bit wide.)
1844    
1845    Also started to add similar support for Int64, but major pieces of that
1846    are still missing.

1852    Description:
1853    
1854    Structure Word64 is now (almost) complete, word literals and patterns
1855    seem to work.  There are a few odd pieces missing.  In particular,
1856    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1857    at the moment.
1858    
1859    Making Word64 official would mean that LargeWord becomes Word64.  But
1860    this requires extreme care because most word-word conversions have to
1861    go through LargeWord, so making a mistake means loss of efficiency or
1862    worse.  Eventually there will be a solution similar to (but actually
1863    simpler than) what I did with IntInf.

1893    Also:
1894    
1895      - Changend config/srcarchiveurl from a file just
1896        containing the URL string into a file containing
1897        shell script code.  The code has access to the $VERSION variable.
1898      - Made corresponding changes to config/install.sh and config/unpack.
1899      - Default contents of config/srcarchiveurl uses $VERSION and
1900        normally does not have to be edited to reflect a version change.
1901    
1902      (As a result, a version change can be done by just editing
1903       config/version, the rest is now automatic.)

1943    Tag: blume-20041020-standalone-backtrace
1944    Description:
1945    
1946    Added a mechanism for getting back-trace information from standalone
1947    programs.  Here is how it works:
1948    
1949       1. The part of the program from which you want to get backtrace
1950          information (usually the whole program) should be wrapped with
1951          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
1952          main program could be modified from something like
1953    
1954             fun main (pgm, args) = ...
1955    
1956         to
1957    
1958            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1959    
1960       2. To be able to access BackTrace.monitor, you have to add
1961          library $smlnj-tdp/plugins.cm to the .cm file that contains your
1962          main function.
1963    
1964       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1965          CM might have created in the past for your project).
1966    
1967       4. Build the system using this command line:
1968    
1969             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1970                      myprog.cm MyProg.main myprog
1971    
1972          instead of the usual
1973    
1974             ml-build myprog.cm MyProg.main myprog
1975    
1976    I changed a library name:
1977    
1978       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1979    
1980    New libraries:
1981    
1982       $smlnj-tdp/back-trace.cm
1983          -- when loaded causes the back-trace plugin to be installed
1984       $smlnj-tdp/coverage.cm
1985          -- when loaded causes the coverage plugin to be installed

2001    Description:
2002    
2003    * Test coverage tool added!
2004    * Further reorganization of tracing-, debugging-, and profiling support:
2005    
2006        - moved original BTImp -- now called BackTrace -- into a separate
2007          library called $/trace-debug-profile.cm
2008        - eliminated all mentions of BTrace from SMLofNJ.Internals
2009        - only the instrumentation mechanism is now left in the compiler proper
2010        - BackTrace module is a plugin which is NOT plugged in by default
2011        - Coverage module is another such plugin
2012    
2013    To get the benefits of any of these plugin modules, the code in
2014    question must be compiled with tdp instrumentation turned on.  This
2015    can be done by setting SMLofNJ.Internals.TDP.mode to true.
2016    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2017    
2018    Plugins are selected at link time.  (Pre-compiled instrumented code
2019    can be re-loaded with different plugins in effect.)  When an
2020    instrumented module is linked, whatever plugins are at that time
2021    enabled will come into effect for that module.
2022    
2023    To enable the back-trace plugin, load library $/trace-debug-profile.cm
2024    and invoke BackTrace.install() (e.g., from the interactive prompt).
2025    To enable the coverage plugin, load the same library and invoke
2026    Coverage.install().
2027    
2028    Back-traces are generated automatically on uncaught exceptions and
2029    when the code in question explicitly invokes BackTrace.trigger().
2030    
2031    Coverage (and execution frequency-) information must be queried
2032    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2054    This is is preparation of using the original back-trace
2055    instrumentation for other purposes.  "TDP" stands for
2056    Trace/Debug/Profile.
2057    
2058    The control flag controlling whether instrumentation is on or off is now
2059    registered under a different name, so instead of running sml as
2060    
2061     sml -Cinstrument.btrace-mode=true
2062

2084    treats subsequent occurrences of "group", "library", "source", "is",
2085    "*", and "-" as ordinary identifiers rather than keywords.
2086    
2087    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
2088    is supposed to accept a tool argument called "source", but this did
2089    not work because of the clash with the keyword.

2133    
2134    * Moved the "version" magic into its own little library under
2135      src/system/smlnj/internal.  This avoids expensive reconstruction of
2136      a stable src/compiler/core.cm.
2137    
2138    * At the same time, structure CompilerVersion is now known as
2139      structure SMLNJVersion.
2140    
2141    * Arranged for the version tool to NOT kick in when rebuilding the system
2142      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
2143      Also, loading the versiontool does not work when rebuilding the system
2144      because CM is not properly initialized at that time.

2149    Tag: blume-20040929-autoversion
2150    Description:
2151    
2152    Implemented some CM magic to have
2153        file src/compiler/TopLevel/main/version.sml
2154    generated automagically.
2155    The version is taken from two files: config/version and config/release.
2156    The first is expected to contain a two-part version number such as 110.49.
2157    The second should contain a single number, but it may be missing.
2158    
2159    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2160    time the version tool is loaded (which is the first time you say CMB.make),
2161    then the tool will increment the value stored in config/release every
2162    time CMB.make is invoked.
2163    
2164    The binfile format is now insensitive to anything beyond the first
2165    two components of a version number, so bumping the release does not render
2166    binfiles incompatible.  Auto-bumping can be used to keep track of versions
2167    during development without invalidating existing binfiles.
2168    
2169    In any case, every CMB.make updates the date information in version.sml.
2170    (This is the date that is printed in the banner.)

2183    Tag: blume-20040927-controls
2184    Description:
2185    
2186    Added two pieces of functionality to the Controls interface:
2187    
2188    1.   val save'restore: 'a control -> unit -> unit
2189    
2190       grabs the current value of the control in stage 1 and restores it
2191       in stage 2.
2192    
2193    2.   val set' : 'a control * 'a -> unit -> unit
2194    
2195       stores the given value into the control in stage 2 (i.e., delayed)
2196       but does all error checking in stage 1.
2197       (This is for string controls that need to do parse their argument --
2198        something that might fail.  In some cases, notably in CM, one
2199        already knows the intended argument but wants to delay the actual
2200        assignment until a time when error recovery would be more difficult.)
2201    
2202    Changed the handling of controls in tool arguments to classes "sml" and
2203    "lazysml":
2204       - use Controls.save'restore as a more robust way of restoring the
2205         old value (in particular: without having to re-parse the string)
2206       - use controls to handle the "overload" keyword in the init group
2207         (I believe this change actually fixes a long-standing obscure bug.)

2212    Tag: blume-20040927-lazysml
2213    Description:
2214    
2215    Added a new tool class called "lazysml" to CM's tool chest.  The only
2216    difference to "sml" is that compilation is done with Control.lazysml
2217    set to true.  A source of class "lazysml" is automatically recognized
2218    by a file name suffix of ".lml".
2219    
2220    In addition to the above feature, the original class "sml" now also
2221    supports a tool argument "lazy" which has the same effect.  As a
2222    result, the following three lines are equivalent:
2223    
2224        foo.sml : lazysml
2225        foo.sml : sml (lazy)
2226        foo.sml (lazy)
2227    
2228    The setting goes into effect both during parsing and during
2229    compilation.  The original setting is restored right after parsing and
2230    after compilation, respectively.
2231    
2232    In addition to all the above, there is also a general mechanism to set
2233    ANY of the "controls" that are available at the command line via
2234    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
2235    apply as well. (In fact, "lazy" is implemented as a special case of
2236    the general mechanism.)
2237    
2238    The .cm file syntax uses a new keyword tool argument called "with".
2239    There are several ways of indicating the desired settings:
2240    
2241        foo.sml (with:parser.quotations=true)
2242        foo.sml (with:(name:parser.quotations value:true))
2243        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2244        foo.sml (with:(name1=value1 name2=value2 ...))
2245        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2246    
2247        etc.
2248    
2249    Another possible abbreviation is to leave out the =v or value:v part
2250    if the name refers to a boolean control (in which case the value is
2251    taken to be true).  Thus, one could get lazy sml also by saying:
2252    
2253        foo.sml (with:parser.lazy-keyword=true)
2254        foo.sml (with:parser.lazy-keyword)
2255        foo.sml (with:(name:parser.lazy-keyword value:true))
2256        foo.sml (with:(name:parser.lazy-keyword))

2608    Description:
2609    
2610    Changed the interface of structures Timer and Unix to match the most
2611    recent Basis spec.
2612    
2613    In the case of Unix there still seems to be an open/weird issue:
2614    
2615       The {text,bin}{In,Out}streamOf functions are supposed to create
2616       fresh streams whenever they are called -- as opposed to have them
2617       return the same stream every time.  This design is supposed to
2618       prevent space leaks caused by proc values hanging on to streams.
2619    
2620       The reap function, on the other hand, is supposed to close the
2621       streams.  This cannot be done without having a handle on the
2622       stream in proc after all...
2623    
2624    I took the liberty to implement the following stopgap solution:
2625    
2626      The proc value hangs on to the most recently created stream(s).
2627      Reap closes those.  If either or both of the two streams hadn't
2628      been created at all yet, then reap will close the corresponding
2629      file descriptors directly.
2630    
2631    PS: I don't understand the original space leak argument anymore.  If
2632    a proc hangs on to the imperative stream, then I/O operations on those
2633    will advance the state of the cached stream and avoid the space leak.

2647    Description:
2648    
2649    CM now ignores (but still accepts) the "owner" information in group
2650    descriptions.  The owner of a group is its next enclosing
2651    library. Each group must have a unique owner.  (There is a virtual
2652    "toplevel" library that owns groups which are not nested within a real
2653    library.)  Previously, each group had to explicitly declare its owner,
2654    and CM would check that such a declaration is correct.  The new scheme
2655    is to have CM check that for each group there is precisely one owning
2656    library.
2657    
2658    The advantage of the new scheme is that the programmer no longer needs
2659    to maintain the somewhat annoying owner information.  The downside is
2660    that CM cannot enforce the ownership rule across multiple runs of
2661    CM.make.  Fortunately, enclosing the same group in two different
2662    libraries A and B which are not part of the same program does not
2663    cause real problems.

2669    Description:
2670    
2671    Made the win32 version work again.  (Strangely, a misplaced comma had
2672    slipped into win32-process.c which prevented the runtime from being
2673    compiled correctly.)
2674    
2675    Also, included a minor addition to ml-build.bat analogous to what was
2676    done in blume-20040519-ml-build.

2682    Description:
2683    
2684    Arranged for ml-build to clean up after itself a little bit better.
2685    The script generates a temporary SML source file and compiles it using
2686    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
2687    gets rid of those at the end, so they don't accumulate under .cm.
2688    
2689    This required a minor change to install.sh because the name of the
2690    metadata directory (default: .cm) is actually configurable at
2691    installation time.

2706    Description:
2707    
2708    Added previously missing support for many socket-related functions
2709    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
2710    for the voluminous patch!
2711    
2712    (I have not tested this patch under win32 yet.)
2713    
2714    Here is David's e-mail:
2715    
2716    Hi,
2717    
2718    Attached to this email you find a diff against sml/nj 110.45
2719    that will enable socket support under Windows.
2720    
2721    To apply the patch (using unix or cygwin)
2722    1) gunzip runtime.diff.gz
2723    2) "cd" into "src/runtime" in the source tree of a fresh
2724       110.45 installation.
2725    3) patch -p 1 < [your/path/to]runtime.diff
2726    
2727    The code compiles fine but has NOT yet been extensively tested.
2728    I only ran a few tests for basic socket client functionality
2729    (which worked fine).  Especially the functions that use ioctl
2730    are not tested at all and might not work (see below).
2731    
2732    I implemented this since we want to move to a newer version of sml/nj
2733    but need socket support in order to use it.  This is the first time I
2734    even had a look at the sml/nj source,  so please review my changes
2735    before making this part of the distribution!  Here are a few issues
2736    that I think might be better for someone to solve who is more
2737    familiar with the sml/nj source (and socket programming):
2738    
2739    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2740      exception since I could not figure out what the windows equivalent
2741      of these functions is
2742    
2743    - In sockets-osdep.h there are a some #include statements that are
2744      only used in a few files that include sockets-osdep.h
2745    
2746    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2747      does not process its return value since I don't know how to
2748      report an error upwards.
2749    
2750    - It would probably be good to have a call to WSACleanup() when
2751      the library is unloaded (if there is such a possibility).
2752      Otherwise I think Windows will take care of this automatically
2753      when the process finishes.
2754    
2755    - I used ioctlsocket() as a replacement for ioctl() but I have
2756      no idea if that is actually the proper replacement on Windows.
2757    
2758    - All these issues are marked in the code by "FIXME" comments.
2759    
2760    We use sml/nj extensively in our products and are quite happy
2761    with it.  I hope this contribution will help you.
2762    
2763    Keep up the good work!
2764

2800    The installer now honors the "src-smlnj" target again, although its meaning
2801    has changed from "all sources required for the compiler" to "all sources
2802    the installer knows about".  In other words, if you enable "src-smlnj"
2803    in the "targets" file, then the installer will pull in sources for
2804    everything.  (Notice that this refers to source code only.  Compiled
2805    code is still only installed for modules that were requested explicitly
2806    or which are required for other modules that were requested explicitly.)

2840    Description:
2841    
2842    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
2843    of SML/NJ.  The problem is that
2844    
2845       lib = dlopen(NULL, ...)
2846       f   = dlsym(lib, "malloc");
2847    
2848    does not work on Windows unless we explicitly export symbols
2849    such as 'malloc' during linking.  We fixed this by explicitly
2850    exporting the required symbols with the magic gcc incantation:
2851    
2852        -Wl,--export-all cygwin.def
2853    
2854    where cygwin.def is a file containing all the symbols that
2855    we wish to export.
2856    
2857    I suspect this is a Windows problem and we'll have to
2858    do the same (somehow with windows compilers) when
2859    we build the native win32 version with the system
2860    calls LoadLibrary/GetProcAddress.

2932    there does not seem to be any reason not to move all libraries into
2933    lib during installation.  I originally implemented this directive as a
2934    backward-compatibility feature when I first introduced the new CM.
2935    Now that things have been stable for a long time and going back to the
2936    old CM is not an option, there is no reason to keep it around.)

2986    Description:
2987    
2988    I modified the read-eval-print loop so that the autoloader gets
2989    invoked whenever the prettyprinter tries to look up a symbol that
2990    is not currently defined in the toplevel environment but which
2991    appears in CM's autoload registry.  As a result, we see far fewer of
2992    those ?.Foo.Bar.xxx names in the prettyprinter's output.
2993    
2994    In addition to this I tried to clean up some pieces of the Basis
2995    implementation (e.g., Socket, Word8Array) in order to prevent other
2996    instances of these ?.Foo.Bar.xxx names from being printed.
2997    
2998    The mechanism that picks names for types still needs some work, though.
2999    (Right now it seems that if there is a type A.t which is defined to
3000    be B.u, but B is unavailable at toplevel, then A.t gets printed as
3001    "?.B.u" although the perhaps more sensible solution would be to use
3002    "A.t" in this case.  In other words, the prettyprinter should follow
3003    a chain of DEFtycs not farther than there are corresponding toplevel
3004    names in the current environment.)

3010    Description:
3011    
3012    Another installer tweak:  All the ML code for the installer is now
3013    compiled during CMB.make and put into a little library called
3014    $smlnj/installer.cm.  The installation then simply invokes
3015    
3016       sml -m $smlnj/installer.cm
3017    
3018    and everything happens automagically.
3019    
3020    Win32:  ML code senses value of environment variable SMLNJ_HOME.
3021    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
3022            and BINDIR.
3023    
3024    The new scheme guarantees that the ML code responsible for the installation
3025    is in sync with the APIs of the main system.  Also, the installer is
3026    somewhat faster because the installer script is precompiled.

3043    Tag: blume-20030924-sockets
3044    Description:
3045    
3046    1. Fixed SOCKET API and implementation to match Basis spec.
3047       This required changing the internal representation of sockets to one
3048       that remembers (for each socket file descriptor) whether it is currently
3049       blocking or non-blocking.  This state is maintained lazily (i.e., a system
3050       call is made only if the state actually needs to change).
3051    
3052    2. OS-specific details of sockets were moved into separate files, thus
3053       making it possible to unify the bulk of the socket implementations
3054       between Unix and Win32.
3055    
3056    3. CML's socket API changed accordingly.
3057       (Note that we need to remove non-blocking functions from this API
3058       since they are redundant in the case of CML!)
3059    
3060    4. CML's socket implementation now makes use of non-blocking functions
3061       provided by Basis, thus removing all OS-dependent code from this part
3062       of CML.
3063    
3064    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

3105    Description:
3106    
3107    1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
3108       this seems to be controversial at the moment) and used those in
3109       Posix.ProcEnv.times.
3110    
3111    2. Added Time.{from,to}Nanoseconds to Time.
3112    
3113    3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
3114       For example, fromLargeInt never needs to look at more than 3 "big
3115       digits" to get its 53 bits of precision.

3121    Description:
3122    
3123    Added an entry to the primitive environment
3124    (compiler/Semant/statenv/prim.sml) for int32->real64 conversion and
3125    added code to compiler/CodeGen/main/mlriscGen.sml to implement it.
3126    
3127    Removed some of the "magic" constants in real64.sml and replaced them
3128    with code that generates these values from their corresponding
3129    integer counterparts.
3130    
3131    Made all(?) the slice-related changes to the Basis and made everything
3132    compile again...

3148    Minor bugfix in config/libinstall (set anchor with path to
3149    standalone tool after installing it, otherwise libraries that
3150    need ml-lex or ml-yacc won't compile the first time the installer
3151    runs).

3177    Description:
3178    
3179    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3180    Modified config/install.bat to take advantage of it.  Also modified
3181    config/install.sh (and called it config/new-install.sh) to take advantage
3182    of it on Unix systems.  (The SML code is (supposed to be) platform-
3183    independent.)
3184    
3185    The installer can now install everything under Win32
3186    as well as under *nix as long as it compiles.
3187    
3188    Other changes:
3189    
3190      - made CML compile again under Win32
3191      - made eXene compile under Win32 (by providing a fake structure UnixSock
3192        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3193      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3194        same as type int;  under Win32 it isn't
3195      - fixed some slice-related problems in the win32-specific parts of CML
3196      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3197        (under Win32, the volume name is case-insensitive, and the
3198        OS.Path code compares volume names for equality)

3205    
3206    Made Win32 version of OS.FileSys.fullPath return current directory
3207    when given an empty string.  This is what the spec says, and incidentally,
3208    CM depends on it.  (CM otherwise goes into an infinite loop in certain
3209    cases when presented with the name of a non-existing .cm file.)

3215    Description:
3216    
3217      1. Changed interface to vectors and arrays in Basis to match
3218         (draft) Basis spec.
3219      2. Added signatures and implementations of slices according to
3220         Basis spec.
3221      3. Edited source code throughout the system to make it compile again
3222         under 1. and 2.  (In some cases code had to be added to have it
3223         match the new signatures.)
3224      4. MLRISC should be backward-compatible: the copies of the originals
3225         of files that needed to change under 3. were retained, the .cm files
3226         check the compiler version number and use old versions when
3227         appropriate.
3228      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3229         dirstream -> string option (in accordance with Basis spec).
3230      6. When generating code that counts lines, ml-lex used function
3231         CharVector.foldli, taking advantage of its old interface.
3232         This has been replaced with the corresponding code from
3233         CharVectorSlice.  (html-lex must be re-lexed!)
3234      7. BitArray in smlnj-lib/Util has been extended/modified to match the
3235         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
3236      8. Removed temporary additions (fromInternal, toInternal) from the
3237         (now obsolete) IntInf in smlnj-lib/Util.
3238      9. Cleaned up structure Byte.
3239     10. Added localOffset, scan, and fromString to Date (according to spec).
3240         Cleaned/corrected implementation of Date.
3241         (Still need to check for correctness; implement better canonicalizeDate.)
3242     11. Added "scan" to signature IEEE_REAL.
3243     12. Some improvements to IntInf [in particular: efficiency-hack for
3244         mod and rem when second operand is 2 (for parity checks).]
3245     13. Changed representation of type Time.time, using a single IntInf.int
3246         value counting microseconds.  This considerably simplified the
3247         implementation of structure Time.  We now support negative time
3248         values; scan and fromString handle signs.
3249     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3250         ArraySlice).

3256    Description:
3257    
3258    This is a major update which comes with a version number bump
3259    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3260    and an implementation of IntInf in the Basis.
3261    
3262    There are a fairly large number of related changes and updates throughout
3263    the system:
3264    
3265    Basis:
3266            - Implemented IntInf.
3267            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3268            - Added some missing Real64 operations, most notably Real.toLargeInt.
3269            - Added FixedInt as a synonym for Int32.
3270    
3271    compiler:
3272            * Added support for a built-in intinf type.
3273              - literals
3274              - pattern matching
3275              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3276              - overloading on literals and operations
3277    
3278            This required adding a primitive type intinf, some additional
3279            primops, and implementations for several non-trivial intinf
3280            operations in Core.  (The intinf type is completely abstract
3281            to the compiler; all operations get delegated back to the Core.)
3282    
3283            * Intinf equality is handled by polyequal.  However, the compiler
3284            does not print its usual warning in this case (since polyequal
3285            is the right thing to do there).
3286    
3287            * Improved the organization of structure InlineT.
3288    
3289            * A word about conversion primops:
3290            If conversions involving intinf do not cancel out during
3291            CPS contract, then the compiler must insert calls to Core functions.
3292            Since all core access must be resolved already during the FLINT
3293            translate phase, it would be too late a the time of CPS contract
3294            to add new Core calls.  For this reason, conversion primops
3295            for intinf carry two arguments:  1. the numeric argument that
3296            they are supposed to convert, and 2. the Core function that
3297            can help with this conversion if necessary.  If CPS contract
3298            eliminates a primop, then the associated Core function becomes
3299            dead and goes away.  Intinf conversion primops that do not get
3300            eliminated by CPS contract get rewritten into calls of their
3301            core functions by a separate, new phase.
3302    
3303    interactive system:
3304            - Control.Print.intinfDepth controls max length of intinf constants
3305            being printed. (Analogous to Control.Print.stringDepth.)
3306            - Cleanup in printutil and pputil: got rid of unused stuff and
3307            duplicates; replaced some of the code with code that makes better
3308            use of library functionality.
3309    
3310    CM:
3311            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3312            are no longer silent.
3313    
3314    CKIT:
3315            Fixed mismatched uses of Int32 and LargeInt.  I always decided
3316            in favor of LargeInt -- which is now the same as IntInf.
3317            CKIT-knowledgable people should check whether this is what's
3318            intended and otherwise change things back to using Int32 or
3319            FixedInt.
