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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

982    spurious dependency to a non-existing file.  (This is a simple fix.
983    It might need further looking into.)

1074    Hooked code for Darwin-specific Intel ABI into main compiler.
1075    (This is a temporary solution which relies on the fact that the
1076    compiler itself does not use NLFFI.  Eventually we need to divorce
1077    intel mac from generic x86 unix code and make separate sets of binaries.)

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

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

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

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

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

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

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

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

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

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

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

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

2010     sml -Cinstrument.btrace-mode=true

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

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

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

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

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

2252    
2253    Put target "mlrisc" back into the default list.
2254    (There is no harm in having it, and some users have expressed their
2255    wish to have "mlrisc" included by default.)

2297    Description:
2298    
2299    Upon request by Johannes Joemann:
2300    
2301    - improved ML code of installer to fall back to coping when renaming
2302      fails (i.e., when source and target are on different file systems);
2303      the code compiles but has yet to be tested in anger
2304    - removed mlrisc from list of default targets (config/targets)

2353    
2354    Bug fix from Carl Hauser:
2355    
2356    single_source_shortest_paths in dijkstra.sml was observed to get wrong
2357    answers (by comparing to single_source_shortest_paths in bellman-ford.sml).
2358    
2359    The problem is that following the expression A.update(dist,s,Num.zero)
2360    it is necessary to update the priority queue using Q.decreaseWeight(Q,s).

2366    Description:
2367    
2368    Fiddled with handling of command-line options:
2369    
2370      * sml now quits after processing the command line
2371        if -H, -S, -h<n>, or -s<n> appears as the last
2372        command-line argument
2373      * a new option -q terminates the session when encountered on
2374        the command line; subsequent arguments will be ignored
2375      * bug fixes: short (erroneous) arguments are no longer ignored
2376        completely

2432    
2433    Gearing up towards 110.47...
2434    
2435    - various minor bugfixes to ml-nlffigen
2436    - a beginning of a manual for nlffi
2437    
2438    - eliminated 'export name=value' in config/install.sh as this does
2439      not work with certain versions of /bin/sh
2440      (Thanks to David King at Motorola for catching this.)
2441    
2442    - several bugfixes provided or suggested by David Hansel at Reactive Systems:
2443      - added a test for tm==NULL to gmtime.c and localtime.c
2444      - applied patch for incorrect GetFileTime under win32

2454      for a typedef to an incomplete type, but leave out the "typ" member.
2455      (This is just for consistency.)
2456    - Started to produce what is supposed to become better (i.e., comprehensive)
2457      documentation of what ml-nlffigen does and produces.

2466    (ml-nlffigen, cproto.sml) that conveys C function interface
2467    information to the code generator.
2468    
2469    However, the actual architecture-specific implementation of function
2470    arguments and results that are C unions is still not implemented.
