188    
189    - Aaron: fixed a number of bugs in ml-ulex.
190    - Matthias:
191       - added CM control "cm.force-tools"; this is false by default;
192         when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
193         will be forced to run regardless of whether or not their targets
194         are up-to-date
195       - changed installer code so that config/install.sh will re-build
196         heap images for all tools even if those heap images already existed

202    
203    After Aaron Turon's bug fix for ml-ulex (handling the ^ character
204    in legacy mode), re-ran the lexer generator on all lex input files
205    and committed the results.
206    
207    This should fix the problem with ckit and nlffi that was reported
208    by Vesa A. Norrman.

223    
224    3rd merge of base from primop-branch-3 into the trunk.
225    Additional bug fixes included:
226    
227     * Timer.cpu_timer, etc. type printing corrected (by making
228         Timer have opaque sig constraint in basis/Implementation/timer.sml)
229     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by

235    Description:
236    
237    Fixed some bugs in new Div code in FLINT/trans/translate.sml.
238    
239    Also, changed the handling of "no core access":  When translate.sml
240    needs access to a core exception at a time when the core has not
241    been set up yet (this only happens when compiling system/smlnj/init/*),
242    then don't bother generating the corresponding tests.
243    
244    The old scheme was to generate a bogus value to be used in place of
245    the exception.  Unfortunately, that confuses the plambda type checker.
246    Moreover, it does not do any good, because at runtime we don't expect
247    such an exception to be ever raised.  (The code in system/smlnj/init/*
248    has to be written very carefully with this in mind!)

260    Description:
261    
262    FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
263    with an explicit test for zero division.  This should fixes several
264    regressions and makes it possible for downstream optimization phases
265    to treat these operations as "pure" when they are applied to unsigned
266    operands.

281    
282    A number of fixes related to the formatting of dates.  These include fixes
283    for bugs #1415 and #1416.  We also now correctly handle format characters that
284    lie outside the specified set.

288    Date: 2007/05/23 22:30:00 CDT
289    Description:
290    
291    CMB (and CM) now automatically defines the CM "preprocessor" symbol
292    NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
293    
294      (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
295       CM_SLAVE_MODE is defined in attached slaves while running CM.make
296       or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
297       while running CMB.make.  The point is that the single symbol
298       NO_PLUGINS is definde in all three cases.)
299    
300    I changed the three locations within the sources that get compiled
301    during CMB.make where ml-yacc or ml-lex input is processed: When
302    NO_PLUGINS defined, then the use of the mlyacc and mllex tools
303    is bypassed.
304    
305    When bootstrapping new versions of the compiler, there can be
306    situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
307    are not available or otherwise not operational.  In this case one can
308    manually define the NO_PLUGINS symbol prior to running CMB.make().  To
309    do so, the following command should be issued at the interactive
310    prompt:
311    
312       #set (CMB.symval "NO_PLUGINS") (SOME 1);
313    
314    A CMB.make with NO_PLUGINS defined relies on the existence of the
315    files that normally would be generated by ml-yacc and ml-lex.
316    (Copies of these files are in the repository.)

332    Description:
333    
334    Changed the installation mechanism for CM tool plugins.  These are
335    just libaries and now get installed like ordinary libaries.
336    
337    There are now a number of new installation targets that give some
338    fine-grain control over what classes and suffixes are known, and what
339    they will map to.
340    See config/targets for details.
341    
342    The code that caused plugin installation as part of running a
343    tool's "build" script has been removed.  (The build script is for
344    building, not for installing.)

349    Description:
350    
351    Added a boolean control named cm.tolerate-tool-failures (env. variable
352    name: CM_TOLERATE_TOOL_FAILURES).  The default is false and makes
353    CM fail if a shell tool reports a non-success exit status.  If
354    the control is set to true, then CM will press on after tool failures
355    in the event that the target files exist (even though they are
356    considered outdated).  Turning the control to true can be useful for
357    bootstrapping.

362    Description:
363    
364    Merge of ml-lpt revisions for 110.64.
365    
366    The name of several ml-lpt-lib modules has changed:
367      Repair        => AntlrRepair
368      StreamPos     => AntlrStreamPos
369      ErrHandlerFn  => AntlrErrHandler
370      EBNF          => AntlrEBNF
371    
372    The ml-antlr specification format has changed: declarations such as
373    %tokens and nonterminal definitions can occur *multiple* times in the
374    same specification.  The semantics are such that each new declaration
375    extends the previous ones.  This does not apply to %start or %name,
376    of course.
377    
378    Importing a grammar via %import now includes *all* declarations in from
379    the imported grammar, except for %name, %entry, and %start.  Tokens
380    and nonterminals can be dropped using the new %dropping clause of the
381    %import directive; the separate %drop and %extend have been removed.
382    
383    We now allow optional type annotations on nonterminals, using the %nonterms
384    directive as in ml-yacc.
385    
386    The refcell construct is now implemented using SML's regular reference
387    cells, so the :== and !! notation has been deprecated.
388    
389    The ml-antlr tool now does much more checking of specifications, and
390    its error messages have been greatly improved.  Error repair for
391    generated parsers has been completely rewritten, and is now both
392    much faster and more accurate.
393    
394    ml-ulex is now more lenient with escape codes (non-SML-standard
395    escape codes are now interpreted literally, so e.g. \| denotes "|").
396    Also, character classes may now include a "-" character at the beginning
397    as is standard in most other regexp tools.
398    
399    All of these changes are documented in the user guide, which has
400    been updated and improved with this merge.

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

553    Added preliminary support in MLRISC for Staged Allocation, a technique
554    for specifying calling conventions (see
555    http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
556    Initially, we plan to use this code to generate C calls for the AMD64.
557    
558    The staged allocation code base resides in MLRISC/staged-allocation,
559    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

629    the interface for creating streams in ml-ulex (we now support
630    stream creation from several kinds of sources).  Overall, the
631    tools are now quite stable, and their interfaces are unlikely to
632    change in a way that would break compatibility.  More work,
633    however, is needed in the documentation.

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

643    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
644    and ml-antlr.
645    
646    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
647    CM tools.  (It turns out to be too messy to do otherwise because
648    there is too much code that during installation relies on the presence
649    of these tools -- resulting in a tricky ordering problem.)

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

730    
731    Added code to CM's "standard shell tool" implementation which
732    causes it to tolerate (with a warning) the situation where the shell
733    command fails (e.g., due to the shell command's non-existence)
734    as long as all target files exist.
735    
736    This makes it possible to, e.g., build ml-yacc from sources even if
737    svn checkout messed up the time stamps on files in such a way that
738    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
739    be needed to re-process yacc.grm, but obviously it might not yet be
740    available at that time.)

781    
782    New working release (110.60).  NEW BOOTFILES!
783    
784    This is the first subversion-hosted release.  There are also changes
785    to the directory layout.  Here is a table:
786    
787    (All pathnames are relative to the SML/NJ "root" directory.)
788    
789      config -> config
790    
791      src/cm -> base/cm
792      src/compiler -> base/compiler
793      src/runtime -> base/runtime
794      src/system -> base/system
795    
796      src/cm/pgraph -> pgraph
797    
798      src/READMES -> base/READMES
799      src/$notefile -> base/NOTES/$notefile
800         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
801                           MACOSXINSTALL WININSTALL
802    
803      src/smlnj-lib -> smlnj-lib
804      src/MLRISC -> MLRISC
805      ckit -> ckit
806      src/cml -> cml
807      src/eXene -> eXene
808      src/heap2asm -> heap2asm
809      src/lexgen -> lexgen
810      src/ml-burg -> ml-burg
811      src/ml-lex -> ml-lex
812      src/ml-yacc -> ml-yacc
813      src/ml-nlffi-lib -> nlffi/lib
814      src/ml-nlffigen -> nlffi/gen
815      src/smlnj-c -> smlnj-c
816      src/tools/TraceDebugProf -> trace-debug-profile
817    
818    In addition, there is also a new
819    
820      ml-lpt
821    
822    directory containing two new program generator tools: ml-ulex and
823    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
824    LL(k) parser generator). These tools are currently "beta-quality"
825    
826    The latest versios of the sources can now be obtained anonymously
827    via subversion.  For this, it is useful to first check out
828    
829       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
830    
831    and put the resulting directory on your shell's PATH.  This provides
832    access to three shell scripts: checkout-all.sh, stat-all.sh,
833    and refresh-all.sh.
834    
835    To create a freshly checked-out copy of the sources, do
836    
837       checkout-all.sh [dir]
838    
839    where dir is the optional SML/NJ root directory (default is ".").
840    
841    This creates the above directory layout.  Each subdirectory of
842    the root is under individual subversion control.  The stat-all.sh
843    and refresh-al.sh scripts apply "svn stat" or "svn update" to
844    each of these subtrees.
845    
846    ----------------------------------------------------------------------
847    Name: Matthias Blume (http://www.tti-c.org/blume/)
848    Date: 2006/11/02 12:20:00 CST
849    Description:
850    
851    Reorganized directory layout.
852    
853    This is a temporary solution, more reorganization is to come.
854    
855    The basic idea is to have a number of toplevel trees, each corresponding
856    to a well-defined part of the overall system.  Each part can be
857    maintained individually, even in separate source repositories,
858    although currently we still serve everything out of the main
859    smlnj-gforge tree.
860    
861    Installer and and scripts have been updated to reflect the new
862    layout.  The installer (base/src/system/smlnj/installer) is now
863    "scriptable" to avoid burning too much knowledge about the
864    layout into SML source code.  The main script used by the installer
865    is in config/actions.
866    
867    The main change is that many of the subdirectories of what used to
868    be known as "src" have moved to the toplevel.  The "src" directory
869    itself has moved down into a subtree called "base".  (We may eventually
870    get rid of the extra level of indirection represented by "src".)
871    
872    The layout is now as follows:
873    
874      toplevel tree name | default repository
875                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
876      -------------------+----------------------------------------------------
877      config             | $gf/config/trunk
878                         |
879      base               | $gf/sml/trunk
880                         |
881      smlnj-lib          | $gf/smlnj-lib/trunk
882      MLRISC             | $gf/MLRISC/trunk
883                         |
884      ml-yacc            | $gf/ml-yacc/trunk
885      ml-lex             | $gf/ml-lex/trunk
886      ml-burg            | $gf/ml-burg/trunk
887      lexgen             | $gf/lexgen/trunk
888      heap2asm           | $gf/heap2asm/trunk
889                         |
890      cml                | $gf/cml/trunk
891      eXene              | $gf/eXene/trunk
892      ckit               | $gf/ckit/trunk
893      nlffi              | $gf/nlffi/trunk
894                         |
895      smlnj-c            | $gf/smlnj-c/trunk
896    
897    In $gf/admin there are a few useful shell scripts for checking out
898    and maintaining the entire collection of trees:
899    
900       admin/checkout-all.sh [dir]
901          -- optionally creates dir and checks out all trees from their
902             default repositories; if dir is missing, checkout into .
903       admin/refresh-all.sh [dir]
904          -- looks at all trees (from the above list) in dir (default: .)
905             and runs "svn update" if the tree exists and is under
906             subversion control;
907             non-existing or non-subversion trees are skipped
908       admin/stat-all.sh [dir]
909          -- like refresh-all.sh, but runs "svn stat" instead

932         * committed changes to eXene from Alley Stoughton:
933             "fixed bugs in X authorization and resource handling, as well
934              as in the pile and viewport widgets"
935    
936      Runtime:
937        * fixed linking problem with NetBSD 3.x.
938    
939      Lexgen:
940        * lexgen tool handles non-ascii characters in 7-bit mode the same
941          way that ml-lex does
942    
943        * lexgen propagates exceptions the same way that ml-lex does
944    
945      CML:
946        * Fixed a bug in the SyncVar polling functions (iGetPoll,
947          mTakePoll, and mGetPoll) that could lead to livelock.

955    Implemented ml-makedepend (i.e., CM.sources) in a better (more robust)
956    way.  This should hopefully fix the ml-makedepend problem permanently.

1058    (This is a temporary solution which relies on the fact that the

1089    Description:
1090    
1091    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
1092    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
1093    at the time when config/preloads is processed, the library has to
1094    be referred to by another name.  In 110.57 this would be
1095    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
1096    to be valid as well.)

1151    Tag: blume-22051115-versiontool
1152    Description:
1153    
1154    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
1155    file gets loaded as a tool -- by the equivalent of CM.make during the
1156    run of CMB.make.  Thus, CMB's path configuration is meaningless for
1157    it.  Instead, it has the status of "user code", so it should use
1158    $/basis.cm to refer to the Basis library.  (At least that's true for
1159    the purpose of bootstrapping the previous change.  In the future it
1160    might make sense to have versiontool.cm refer to
1161    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1162    compiler itself uses.)
1163    
1164    Also patched src/system/testml to have it activate those extra anchor
1165    bindings in config/extrapathconfig.

1170    Tag: blume-22051115-libraries
1171    Description:
1172    
1173    This change affects the way the following libraries are tied into
1174    the system:
1175    
1176       $/basis.cm
1177       $/smlnj-lib.cm
1178       $/pp-lib.cm
1179       $/controls-lib.cm
1180       $/html-lib.cm
1181       $/ml-yacc-lib.cm
1182    
1183    These libraries are now internally (as seen from the source code
1184    of the implementation itself) known by the following names:
1185    
1186       $smlnj/basis/basis.cm
1187       $smlnj/smlnj-lib/smlnj-lib.cm
1188       $smlnj/smlnj-lib/pp-lib.cm
1189       $smlnj/smlnj-lib/controls-lib.cm
1190       $smlnj/smlnj-lib/html-lib.cm
1191       $smlnj/ml-yacc/ml-yacc-lib.cm
1192    
1193    This makes it possible to work with code that requires different
1194    versions of these libraries, and which refers to these libraries using
1195    their "default" names (i.e., the first set of names above).  In other
1196    words, one can un-define or re-define those default names without
1197    compromising the proper functioning of the compiler itself.
1198    
1199    A similar procedure had already been performed for several of the
1200    MLRISC libraries that are linked into the compiler.  I did some
1201    cleanup on this code.
1202    
1203    A new file in the config directory (named extrapathconfig) is
1204    responsible for setting up path anchors that the compiler itself does
1205    not need, but that are typically required by user code.

1384    Tag: blume-20050516-redump-heap
1385    Description:
1386    
1387    Added mechanism for re-creating a heap file for the interactive system
1388    after configuration variables have been changed.
1389    
1390       CM.redump_heap : string -> unit
1391    
1392    This is much like SMLofNJ.exportML, but starting from the resulting
1393    heap does not return to the caller of CM.redump_heap but
1394    restarts the interactive system from scratch.  The original call of
1395    CM.redump_heap does not return but ends the interactive session.
1396    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1397    
1398    Internally, redump_heap winds the dynamic execution context back to
1399    the point where the original heap image was created and re-executes
1400    the heap image generation code in the boot code.

1516    Tag: blume-20050114-heap2exec
1517    Description:
1518    
1519    Implemented new (but still experimental) heap2exec facility.  This is
1520    tested under Mac OS X and should work under Linux (will test shortly).
1521    It will probably also work on the Sparc (will test some time later).
1522    
1523      - removed old "HACKED_STANDALONE" hack from runtime
1524    
1525    To be able to test this, uncomment the request for "heap2asm" in
1526    config/targets prior to installation.  (Notice that this is different
1527    from "heap2exec" mentioned below.  Not a typo.)
1528    
1529    To perform an actual test, run the command
1530    
1531       $ bin/heap2exec heapfile execfile
1532    
1533    (You can put heap2exec on your shell's path.)
1534    
1535    For example, run
1536    
1537      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1538    
1539    This will create a standalone executable called "mly" which you can
1540    then invoke directly as a command.

1685    Tag: blume-20041124-position
1686    Description:
1687    
1688    The compiler can now be compiled in a mode that makes structure Position
1689    equal to Int64.  The default, however, is unchanged (Position = Int31)
1690    for the time being.
1691    
1692    To enable 64-bit positions, use the following procedure:
1693    
1694    1. Start sml
1695    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1696    3. Type
1697          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1698    4. Run CMB.make() as usual.
1699    
1700    This is barely tested.  The only test so far was a little SML program
1701    counting the number of characters in an 8-gigabyte file by
1702    reading it character-by-character.  That test was successful.
1703    
1704    In support of 64-bit positions, a number of new functions have been
1705    added to the runtime system.

1750    
1751    - In a previous commit, fixed a minor issue with how polyequal is being
1752      translated.  In particular, the code now "looks through" abstractions.
1753      This results in slightly fewer polyEqual warnings and hopefully slightly
1754      more efficient code.  Important examples for where this matters are
1755      the new int64 and word64 types.

1775    32-bit wide.)

1777    Also started to add similar support for Int64, but major pieces of that
1778    are still missing.

1784    Description:
1785    
1786    Structure Word64 is now (almost) complete, word literals and patterns
1787    seem to work.  There are a few odd pieces missing.  In particular,
1788    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1789    at the moment.
1790    
1791    Making Word64 official would mean that LargeWord becomes Word64.  But
1792    this requires extreme care because most word-word conversions have to
1793    go through LargeWord, so making a mistake means loss of efficiency or
1794    worse.  Eventually there will be a solution similar to (but actually
1795    simpler than) what I did with IntInf.

1820    
1821    New working version (110.50).  NEW BOOTFILES!
1822    
1823                 =====================
1824    
1825    Also:
1826    
1827      - Changend config/srcarchiveurl from a file just
1828        containing the URL string into a file containing
1829        shell script code.  The code has access to the $VERSION variable.
1830      - Made corresponding changes to config/install.sh and config/unpack.
1831      - Default contents of config/srcarchiveurl uses $VERSION and
1832        normally does not have to be edited to reflect a version change.
1833    
1834      (As a result, a version change can be done by just editing
1835       config/version, the rest is now automatic.)

1856      - made sure the caller does not add the wrong number of bytes to the
1857        stack pointer after a call of a function returning a struct
1858        (the callee already pops the implicit argument which points to

1875    Tag: blume-20041020-standalone-backtrace
1876    Description:
1877    
1878    Added a mechanism for getting back-trace information from standalone
1879    programs.  Here is how it works:
1880    
1881       1. The part of the program from which you want to get backtrace
1882          information (usually the whole program) should be wrapped with
1883          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
1884          main program could be modified from something like
1885    
1886             fun main (pgm, args) = ...
1887    
1888         to
1889    
1890            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1891    
1892       2. To be able to access BackTrace.monitor, you have to add
1893          library $smlnj-tdp/plugins.cm to the .cm file that contains your
1894          main function.
1895    
1896       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1897          CM might have created in the past for your project).
1898    
1899       4. Build the system using this command line:
1900    
1901             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1902                      myprog.cm MyProg.main myprog
1903    
1904          instead of the usual
1905    
1906             ml-build myprog.cm MyProg.main myprog
1907    
1908    I changed a library name:
1909    
1910       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1911    
1912    New libraries:
1913    
1914       $smlnj-tdp/back-trace.cm
1915          -- when loaded causes the back-trace plugin to be installed
1916       $smlnj-tdp/coverage.cm
1917          -- when loaded causes the coverage plugin to be installed

1933    Description:
1934    
1935    * Test coverage tool added!
1936    * Further reorganization of tracing-, debugging-, and profiling support:
1937    
1938        - moved original BTImp -- now called BackTrace -- into a separate
1939          library called $/trace-debug-profile.cm
1940        - eliminated all mentions of BTrace from SMLofNJ.Internals
1941        - only the instrumentation mechanism is now left in the compiler proper
1942        - BackTrace module is a plugin which is NOT plugged in by default
1943        - Coverage module is another such plugin
1944    
1945    To get the benefits of any of these plugin modules, the code in
1946    question must be compiled with tdp instrumentation turned on.  This
1947    can be done by setting SMLofNJ.Internals.TDP.mode to true.
1948    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1949    
1950    Plugins are selected at link time.  (Pre-compiled instrumented code
1951    can be re-loaded with different plugins in effect.)  When an
1952    instrumented module is linked, whatever plugins are at that time
1953    enabled will come into effect for that module.
1954    
1955    To enable the back-trace plugin, load library $/trace-debug-profile.cm
1956    and invoke BackTrace.install() (e.g., from the interactive prompt).
1957    To enable the coverage plugin, load the same library and invoke
1958    Coverage.install().
1959    
1960    Back-traces are generated automatically on uncaught exceptions and
1961    when the code in question explicitly invokes BackTrace.trigger().
1962    
1963    Coverage (and execution frequency-) information must be queried
1964    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

1980    
1981    Some rationalization of names:

1984       etc.
1985    
1986    This is is preparation of using the original back-trace
1987    instrumentation for other purposes.  "TDP" stands for
1988    Trace/Debug/Profile.
1989    
1990    The control flag controlling whether instrumentation is on or off is now
1991    registered under a different name, so instead of running sml as
1992    
1993     sml -Cinstrument.btrace-mode=true
1994    
1995    one has to say
1996

2013    Description:
2014    
2015    Fixed handling of keywords in .cm files: After seeing "is" the lexer
2016    treats subsequent occurrences of "group", "library", "source", "is",
2017    "*", and "-" as ordinary identifiers rather than keywords.
2018    
2019    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
2020    is supposed to accept a tool argument called "source", but this did
2021    not work because of the clash with the keyword.

2064    Description:
2065    
2066    * Moved the "version" magic into its own little library under
2067      src/system/smlnj/internal.  This avoids expensive reconstruction of
2068      a stable src/compiler/core.cm.
2069    
2070    * At the same time, structure CompilerVersion is now known as
2071      structure SMLNJVersion.
2072    
2073    * Arranged for the version tool to NOT kick in when rebuilding the system
2074      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
2075      Also, loading the versiontool does not work when rebuilding the system
2076      because CM is not properly initialized at that time.

2081    Tag: blume-20040929-autoversion
2082    Description:
2083    
2084    Implemented some CM magic to have
2085        file src/compiler/TopLevel/main/version.sml
2086    generated automagically.
2087    The version is taken from two files: config/version and config/release.
2088    The first is expected to contain a two-part version number such as 110.49.
2089    The second should contain a single number, but it may be missing.
2090    
2091    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2092    time the version tool is loaded (which is the first time you say CMB.make),
2093    then the tool will increment the value stored in config/release every
2094    time CMB.make is invoked.
2095    
2096    The binfile format is now insensitive to anything beyond the first
2097    two components of a version number, so bumping the release does not render
2098    binfiles incompatible.  Auto-bumping can be used to keep track of versions
2099    during development without invalidating existing binfiles.
2100    
2101    In any case, every CMB.make updates the date information in version.sml.
2102    (This is the date that is printed in the banner.)

2115    Tag: blume-20040927-controls
2116    Description:
2117    
2118    Added two pieces of functionality to the Controls interface:
2119    
2120    1.   val save'restore: 'a control -> unit -> unit
2121    
2122       grabs the current value of the control in stage 1 and restores it
2123       in stage 2.
2124    
2125    2.   val set' : 'a control * 'a -> unit -> unit
2126    
2127       stores the given value into the control in stage 2 (i.e., delayed)
2128       but does all error checking in stage 1.
2129       (This is for string controls that need to do parse their argument --
2130        something that might fail.  In some cases, notably in CM, one
2131        already knows the intended argument but wants to delay the actual
2132        assignment until a time when error recovery would be more difficult.)
2133    
2134    Changed the handling of controls in tool arguments to classes "sml" and
2135    "lazysml":
2136       - use Controls.save'restore as a more robust way of restoring the
2137         old value (in particular: without having to re-parse the string)
2138       - use controls to handle the "overload" keyword in the init group
2139         (I believe this change actually fixes a long-standing obscure bug.)

2144    Tag: blume-20040927-lazysml
2145    Description:
2146    
2147    Added a new tool class called "lazysml" to CM's tool chest.  The only
2148    difference to "sml" is that compilation is done with Control.lazysml
2149    set to true.  A source of class "lazysml" is automatically recognized
2150    by a file name suffix of ".lml".
2151    
2152    In addition to the above feature, the original class "sml" now also
2153    supports a tool argument "lazy" which has the same effect.  As a
2154    result, the following three lines are equivalent:
2155    
2156        foo.sml : lazysml
2157        foo.sml : sml (lazy)
2158        foo.sml (lazy)
2159    
2160    The setting goes into effect both during parsing and during
2161    compilation.  The original setting is restored right after parsing and
2162    after compilation, respectively.
2163    
2164    In addition to all the above, there is also a general mechanism to set
2165    ANY of the "controls" that are available at the command line via
2166    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
2167    apply as well. (In fact, "lazy" is implemented as a special case of
2168    the general mechanism.)
2169    
2170    The .cm file syntax uses a new keyword tool argument called "with".
2171    There are several ways of indicating the desired settings:
2172    
2173        foo.sml (with:parser.quotations=true)
2174        foo.sml (with:(name:parser.quotations value:true))
2175        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2176        foo.sml (with:(name1=value1 name2=value2 ...))
2177        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2178    
2179        etc.
2180    
2181    Another possible abbreviation is to leave out the =v or value:v part
2182    if the name refers to a boolean control (in which case the value is
2183    taken to be true).  Thus, one could get lazy sml also by saying:
2184    
2185        foo.sml (with:parser.lazy-keyword=true)
2186        foo.sml (with:parser.lazy-keyword)
2187        foo.sml (with:(name:parser.lazy-keyword value:true))
2188        foo.sml (with:(name:parser.lazy-keyword))

2540    Description:
2541    
2542    Changed the interface of structures Timer and Unix to match the most
2543    recent Basis spec.
2544    
2545    In the case of Unix there still seems to be an open/weird issue:
2546    
2547       The {text,bin}{In,Out}streamOf functions are supposed to create
2548       fresh streams whenever they are called -- as opposed to have them
2549       return the same stream every time.  This design is supposed to
2550       prevent space leaks caused by proc values hanging on to streams.
2551    
2552       The reap function, on the other hand, is supposed to close the
2553       streams.  This cannot be done without having a handle on the
2554       stream in proc after all...
2555    
2556    I took the liberty to implement the following stopgap solution:
2557    
2558      The proc value hangs on to the most recently created stream(s).
2559      Reap closes those.  If either or both of the two streams hadn't
2560      been created at all yet, then reap will close the corresponding
2561      file descriptors directly.
2562    
2563    PS: I don't understand the original space leak argument anymore.  If
2564    a proc hangs on to the imperative stream, then I/O operations on those
2565    will advance the state of the cached stream and avoid the space leak.

2579    Description:
2580    
2581    CM now ignores (but still accepts) the "owner" information in group
2582    descriptions.  The owner of a group is its next enclosing
2583    library. Each group must have a unique owner.  (There is a virtual
2584    "toplevel" library that owns groups which are not nested within a real
2585    library.)  Previously, each group had to explicitly declare its owner,
2586    and CM would check that such a declaration is correct.  The new scheme
2587    is to have CM check that for each group there is precisely one owning
2588    library.
2589    
2590    The advantage of the new scheme is that the programmer no longer needs
2591    to maintain the somewhat annoying owner information.  The downside is
2592    that CM cannot enforce the ownership rule across multiple runs of
2593    CM.make.  Fortunately, enclosing the same group in two different
2594    libraries A and B which are not part of the same program does not
2595    cause real problems.

2614    Description:
2615    
2616    Arranged for ml-build to clean up after itself a little bit better.
2617    The script generates a temporary SML source file and compiles it using
2618    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
2619    gets rid of those at the end, so they don't accumulate under .cm.
2620    
2621    This required a minor change to install.sh because the name of the
2622    metadata directory (default: .cm) is actually configurable at
2623    installation time.

2640    Added previously missing support for many socket-related functions
2641    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
2642    for the voluminous patch!
2643    
2644    (I have not tested this patch under win32 yet.)
2645    
2646    Here is David's e-mail:
2647    
2648    Hi,
2649    
2650    Attached to this email you find a diff against sml/nj 110.45
2651    that will enable socket support under Windows.
2652    
2653    To apply the patch (using unix or cygwin)
2654    1) gunzip runtime.diff.gz
2655    2) "cd" into "src/runtime" in the source tree of a fresh
2656       110.45 installation.
2657    3) patch -p 1 < [your/path/to]runtime.diff
2658    
2659    The code compiles fine but has NOT yet been extensively tested.
2660    I only ran a few tests for basic socket client functionality
2661    (which worked fine).  Especially the functions that use ioctl
2662    are not tested at all and might not work (see below).
2663    
2664    I implemented this since we want to move to a newer version of sml/nj
2665    but need socket support in order to use it.  This is the first time I
2666    even had a look at the sml/nj source,  so please review my changes
2667    before making this part of the distribution!  Here are a few issues
2668    that I think might be better for someone to solve who is more
2669    familiar with the sml/nj source (and socket programming):
2670    
2671    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2672      exception since I could not figure out what the windows equivalent
2673      of these functions is
2674    
2675    - In sockets-osdep.h there are a some #include statements that are
2676      only used in a few files that include sockets-osdep.h
2677    
2678    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2679      does not process its return value since I don't know how to
2680      report an error upwards.
2681    
2682    - It would probably be good to have a call to WSACleanup() when
2683      the library is unloaded (if there is such a possibility).
2684      Otherwise I think Windows will take care of this automatically
2685      when the process finishes.
2686    
2687    - I used ioctlsocket() as a replacement for ioctl() but I have
2688      no idea if that is actually the proper replacement on Windows.
2689    
2690    - All these issues are marked in the code by "FIXME" comments.
2691    
2692    We use sml/nj extensively in our products and are quite happy
2693    with it.  I hope this contribution will help you.
2694    
2695    Keep up the good work!

2732    The installer now honors the "src-smlnj" target again, although its meaning
2733    has changed from "all sources required for the compiler" to "all sources
2734    the installer knows about".  In other words, if you enable "src-smlnj"
2735    in the "targets" file, then the installer will pull in sources for
2736    everything.  (Notice that this refers to source code only.  Compiled
2737    code is still only installed for modules that were requested explicitly
2738    or which are required for other modules that were requested explicitly.)

2772    Description:
2773    
2774    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
2775    of SML/NJ.  The problem is that
2776    
2777       lib = dlopen(NULL, ...)
2778       f   = dlsym(lib, "malloc");
2779    
2780    does not work on Windows unless we explicitly export symbols
2781    such as 'malloc' during linking.  We fixed this by explicitly
2782    exporting the required symbols with the magic gcc incantation:
2783    
2784        -Wl,--export-all cygwin.def
2785    
2786    where cygwin.def is a file containing all the symbols that
2787    we wish to export.
2788    
2789    I suspect this is a Windows problem and we'll have to
2790    do the same (somehow with windows compilers) when
2791    we build the native win32 version with the system
2792    calls LoadLibrary/GetProcAddress.

2863    (The mechanism was broken and could not be fixed easily.  Moreover,
2864    there does not seem to be any reason not to move all libraries into
2865    lib during installation.  I originally implemented this directive as a
2866    backward-compatibility feature when I first introduced the new CM.
2867    Now that things have been stable for a long time and going back to the
2868    old CM is not an option, there is no reason to keep it around.)

2918    Description:
2919    
2920    I modified the read-eval-print loop so that the autoloader gets
2921    invoked whenever the prettyprinter tries to look up a symbol that
2922    is not currently defined in the toplevel environment but which
2923    appears in CM's autoload registry.  As a result, we see far fewer of
2924    those ?.Foo.Bar.xxx names in the prettyprinter's output.
2925    
2926    In addition to this I tried to clean up some pieces of the Basis
2927    implementation (e.g., Socket, Word8Array) in order to prevent other
2928    instances of these ?.Foo.Bar.xxx names from being printed.
2929    
2930    The mechanism that picks names for types still needs some work, though.
2931    (Right now it seems that if there is a type A.t which is defined to
2932    be B.u, but B is unavailable at toplevel, then A.t gets printed as
2933    "?.B.u" although the perhaps more sensible solution would be to use
2934    "A.t" in this case.  In other words, the prettyprinter should follow
2935    a chain of DEFtycs not farther than there are corresponding toplevel
2936    names in the current environment.)

2942    Description:
2943    
2944    Another installer tweak:  All the ML code for the installer is now
2945    compiled during CMB.make and put into a little library called
2946    $smlnj/installer.cm.  The installation then simply invokes
2947    
2948       sml -m $smlnj/installer.cm
2949    
2950    and everything happens automagically.
2951    
2952    Win32:  ML code senses value of environment variable SMLNJ_HOME.
2953    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
2954            and BINDIR.
2955    
2956    The new scheme guarantees that the ML code responsible for the installation
2957    is in sync with the APIs of the main system.  Also, the installer is
2958    somewhat faster because the installer script is precompiled.

2975    Tag: blume-20030924-sockets
2976    Description:
2977    
2978    1. Fixed SOCKET API and implementation to match Basis spec.
2979       This required changing the internal representation of sockets to one
2980       that remembers (for each socket file descriptor) whether it is currently
2981       blocking or non-blocking.  This state is maintained lazily (i.e., a system
2982       call is made only if the state actually needs to change).
2983    
2984    2. OS-specific details of sockets were moved into separate files, thus
2985       making it possible to unify the bulk of the socket implementations
2986       between Unix and Win32.
2987    
2988    3. CML's socket API changed accordingly.
2989       (Note that we need to remove non-blocking functions from this API
2990       since they are redundant in the case of CML!)
2991    
2992    4. CML's socket implementation now makes use of non-blocking functions
2993       provided by Basis, thus removing all OS-dependent code from this part
2994       of CML.
2995    
2996    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

3109    Description:
3110    
3111    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3112    Modified config/install.bat to take advantage of it.  Also modified
3113    config/install.sh (and called it config/new-install.sh) to take advantage
3114    of it on Unix systems.  (The SML code is (supposed to be) platform-
3115    independent.)
3116    
3117    The installer can now install everything under Win32
3118    as well as under *nix as long as it compiles.
3119    
3120    Other changes:
3121    
3122      - made CML compile again under Win32
3123      - made eXene compile under Win32 (by providing a fake structure UnixSock
3124        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3125      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3126        same as type int;  under Win32 it isn't
3127      - fixed some slice-related problems in the win32-specific parts of CML
3128      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3129        (under Win32, the volume name is case-insensitive, and the
3130        OS.Path code compares volume names for equality)

3136    Description:
3137    
3138    Made Win32 version of OS.FileSys.fullPath return current directory
3139    when given an empty string.  This is what the spec says, and incidentally,
3140    CM depends on it.  (CM otherwise goes into an infinite loop in certain
3141    cases when presented with the name of a non-existing .cm file.)

3147    Description:
3148    
3149      1. Changed interface to vectors and arrays in Basis to match
3150         (draft) Basis spec.
3151      2. Added signatures and implementations of slices according to
3152         Basis spec.
3153      3. Edited source code throughout the system to make it compile again
3154         under 1. and 2.  (In some cases code had to be added to have it
3155         match the new signatures.)
3156      4. MLRISC should be backward-compatible: the copies of the originals
3157         of files that needed to change under 3. were retained, the .cm files
3158         check the compiler version number and use old versions when
3159         appropriate.
3160      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3161         dirstream -> string option (in accordance with Basis spec).
3162      6. When generating code that counts lines, ml-lex used function
3163         CharVector.foldli, taking advantage of its old interface.
3164         This has been replaced with the corresponding code from
3165         CharVectorSlice.  (html-lex must be re-lexed!)
3166      7. BitArray in smlnj-lib/Util has been extended/modified to match the
3167         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
3168      8. Removed temporary additions (fromInternal, toInternal) from the
3169         (now obsolete) IntInf in smlnj-lib/Util.
3170      9. Cleaned up structure Byte.
3171     10. Added localOffset, scan, and fromString to Date (according to spec).
3172         Cleaned/corrected implementation of Date.
3173         (Still need to check for correctness; implement better canonicalizeDate.)
3174     11. Added "scan" to signature IEEE_REAL.
3175     12. Some improvements to IntInf [in particular: efficiency-hack for
3176         mod and rem when second operand is 2 (for parity checks).]
3177     13. Changed representation of type Time.time, using a single IntInf.int
3178         value counting microseconds.  This considerably simplified the
3179         implementation of structure Time.  We now support negative time
3180         values; scan and fromString handle signs.
3181     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3182         ArraySlice).

3188    Description:
3189    
3190    This is a major update which comes with a version number bump
3191    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3192    and an implementation of IntInf in the Basis.
3193    
3194    There are a fairly large number of related changes and updates throughout
3195    the system:
3196    
3197    Basis:
3198            - Implemented IntInf.
3199            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3200            - Added some missing Real64 operations, most notably Real.toLargeInt.
3201            - Added FixedInt as a synonym for Int32.
3202    
3203    compiler:
3204            * Added support for a built-in intinf type.
3205              - literals
3206              - pattern matching
3207              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3208              - overloading on literals and operations
3209    
3210            This required adding a primitive type intinf, some additional
3211            primops, and implementations for several non-trivial intinf
3212            operations in Core.  (The intinf type is completely abstract
3213            to the compiler; all operations get delegated back to the Core.)
3214    
3215            * Intinf equality is handled by polyequal.  However, the compiler
3216            does not print its usual warning in this case (since polyequal
3217            is the right thing to do there).
3218    
3219            * Improved the organization of structure InlineT.
3220    
3221            * A word about conversion primops:
3222            If conversions involving intinf do not cancel out during
3223            CPS contract, then the compiler must insert calls to Core functions.
3224            Since all core access must be resolved already during the FLINT
3225            translate phase, it would be too late a the time of CPS contract
3226            to add new Core calls.  For this reason, conversion primops
3227            for intinf carry two arguments:  1. the numeric argument that
3228            they are supposed to convert, and 2. the Core function that
3229            can help with this conversion if necessary.  If CPS contract
3230            eliminates a primop, then the associated Core function becomes
3231            dead and goes away.  Intinf conversion primops that do not get
3232            eliminated by CPS contract get rewritten into calls of their
3233            core functions by a separate, new phase.
3234    
3235    interactive system:
3236            - Control.Print.intinfDepth controls max length of intinf constants
3237            being printed. (Analogous to Control.Print.stringDepth.)
3238            - Cleanup in printutil and pputil: got rid of unused stuff and
3239            duplicates; replaced some of the code with code that makes better
3240            use of library functionality.
3241    
3242    CM:
3243            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3244            are no longer silent.
3245    
3246    CKIT:
3247            Fixed mismatched uses of Int32 and LargeInt.  I always decided
3248            in favor of LargeInt -- which is now the same as IntInf.
3249            CKIT-knowledgable people should check whether this is what's
3250            intended and otherwise change things back to using Int32 or
3251            FixedInt.
3252    
3253    Throughout the code:
3254            Started using IntInf.int literals and built-in operations
3255            (e.g., comparison with 0) where this seems appropriate.

3262    Description:
3263    
3264    Merging changes from the mcz-branch development branch into trunk.
3265    These changes involve replacement of the emulated old prettyprinter
3266    interface with direct use of the SML/NJ Lib PP library, and fixing
3267    of a couple of bugs (895, 1186) relating to error messages.  A new
3268    prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
3269    has been added.

3276    
3277    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
3278    
3279        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3280    
3281    This patch restores SML/NJ's ability to run under win32.  There are a
3282    number of changes, including fixes for several bugs that had gone
3283    unnoticed until now:
3284    
3285      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3286        trying to run the win32 version from within cygwin.)
3287    
3288      - There are a number of simple .bat scripts that substitute for their
3289        corresponding Unix shell-scripts.  (See below.)
3290    
3291      - The internals of ml-build have been modified slightly.  The main
3292        difference is that instead of calling ".link-sml" (or link-sml.bat)
3293        using OS.Process.system, the ML process delegates this task back
3294        to the script.  Otherwise problems arise in mixed environments such
3295        as Cygwin where scripts look and work like Unix scripts, but
3296        where OS.Process.system cannot run them.
3297    
3298      - In CM, the srcpath pickler used native pathname syntax -- which
3299        is incorrect in the case of cross-compilation.  The new pickle format
3300        is independent of platform-specific naming conventions.
3301    
3302      - Path configuration files (such as lib/pathconfig) can now choose
3303        between native and standard syntax.  Placing a line of the form
3304    
3305            standard!
3306    
3307        into the file causes all subsequent paths to be interpreted using
3308        CM standard pathname syntax (= Unix conventions); a line
3309    
3310            native!
3311    
3312        switches back to native style.  This was needed so that
3313        path config files can be written portably, see src/system/pathconfig.
3314    
3315      - Runtime system:
3316    
3317          - win32-filesys.c:  get_file_time and set_file_time now
3318            access modification time, not creation time.
