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

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.

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

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.

1057    Hooked code for Darwin-specific Intel ABI into main compiler.
1058    (This is a temporary solution which relies on the fact that the

1060    intel mac from generic x86 unix code and make separate sets of binaries.)

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.

1774    but for the time being they don't even make sense because LargeWord is
1775    32-bit wide.)
1776    
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))

2263    
2264       Added a patch to _arch-n-opsys to enable the Cygwin runtime.
2265    The Cygwin runtime is turned on by setting the environment
2266    variable SMLNJ_CYGWIN_RUNTIME to 1.

2280    Description:
2281    
2282    Upon request by Johannes Joemann:
2283    
2284    - improved ML code of installer to fall back to coping when renaming
2285      fails (i.e., when source and target are on different file systems);
2286      the code compiles but has yet to be tested in anger
2287    - removed mlrisc from list of default targets (config/targets)

2336    
2337    Bug fix from Carl Hauser:
2338    
2339    single_source_shortest_paths in dijkstra.sml was observed to get wrong
2340    answers (by comparing to single_source_shortest_paths in bellman-ford.sml).
2341    
2342    The problem is that following the expression A.update(dist,s,Num.zero)
2343    it is necessary to update the priority queue using Q.decreaseWeight(Q,s).

2349    Description:
2350    
2351    Fiddled with handling of command-line options:
2352    
2353      * sml now quits after processing the command line
2354        if -H, -S, -h<n>, or -s<n> appears as the last
2355        command-line argument
2356      * a new option -q terminates the session when encountered on
2357        the command line; subsequent arguments will be ignored
2358      * bug fixes: short (erroneous) arguments are no longer ignored
2359        completely

2369      - Cygwin: manually changed the file cygwin.def.  Some exported symbols have
2370        been altered in the runtime.  We need an automatic way to keep the file

2414    Description:
2415    
2416    Gearing up towards 110.47...
2417    
2418    - various minor bugfixes to ml-nlffigen
2419    - a beginning of a manual for nlffi
2420    
2421    - eliminated 'export name=value' in config/install.sh as this does
2422      not work with certain versions of /bin/sh
2423      (Thanks to David King at Motorola for catching this.)
2424    
2425    - several bugfixes provided or suggested by David Hansel at Reactive Systems:
2426      - added a test for tm==NULL to gmtime.c and localtime.c
2427      - applied patch for incorrect GetFileTime under win32

2436    - Fixed minor issue in ml-nlffigen: Now generate structure T_foo
2437      for a typedef to an incomplete type, but leave out the "typ" member.
2438      (This is just for consistency.)
2439    - Started to produce what is supposed to become better (i.e., comprehensive)
2440      documentation of what ml-nlffigen does and produces.

2447    
2448    Added C_UNION to c-calls/c-types.sml and updated the machinery
2449    (ml-nlffigen, cproto.sml) that conveys C function interface
2450    information to the code generator.
2451    
2452    However, the actual architecture-specific implementation of function
2453    arguments and results that are C unions is still not implemented.
