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

63    Substantially changed the signature and implementation of AMD64
64    SVID.  It now looks similar to the ia32 SVID, yet uses staged
65    allocation.

103    Description:
104    
105    Added preliminary support in MLRISC for Staged Allocation, a technique
106    for specifying calling conventions (see
107    http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
108    Initially, we plan to use this code to generate C calls for the AMD64.
109    
110    The staged allocation code base resides in MLRISC/staged-allocation,
111    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

118      Bug fix: when SaveCState was called with two values to save, a subsequent
119      GC could cause the RestoreCState to fail because the saved state had been
120      promoted to tagless pair.

127        Bug triggered by:
128    
129        val a1 = Word8Array.array(a1, 0w0);
130        val _  = Word8Array.update(a1, 0, 0w128);
131    
132        x86MCEmitter crashed when the immediate operand to MOVB was outside
133    of the range -128 ... 127.  I've changed the code so that the range
134    check is disabled.   Only the low order 8 bits of the immediate operand
135    are now significant.

143    Eliminated any mention of lexgen.  (Lexgen was an early precursor
144    to ml-ulex.)
145    
146    You should update your admin directory, so the shell scripts for
147    maintaining your local copy of the repository reflect this change.

175    Date: 2007/01/31
176    Description:
177    
178    Brought ml-lpt manual up-to-date with the code.  Many minor
179    improvements to the tools, and a few minor bugfixes.  Prepared
180    ml-lpt-lib for integration with new UTF8 structure.  Changed
181    the interface for creating streams in ml-ulex (we now support
182    stream creation from several kinds of sources).  Overall, the
183    tools are now quite stable, and their interfaces are unlikely to
184    change in a way that would break compatibility.  More work,
185    however, is needed in the documentation.

189    Date: 2007/02/01 10:05:00 CST
190    Description:
191    
192    Implemented library installer.  Moved CM plugin code for
193    ml-burg, ml-lex, and ml-yacc out of CM source tree and into
194    their respective trees.  Implemented CM plugin for ml-ulex
195    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
196    and ml-antlr.
197    
198    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
199    CM tools.  (It turns out to be too messy to do otherwise because
200    there is too much code that during installation relies on the presence
201    of these tools -- resulting in a tricky ordering problem.)

206    Description:
207    
208    Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
209    Modified CM's startup code to use shiftArgs as it processes
210    command line arguments.  This way, the init code in each .sml-file
211    or library that is mentioned at the top level will see only
212    those arguments that have not yet been processed at this point.
213    In other words, the init code can "seize control" and process the
214    remaining command line.

271    
272    Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to
273    get the c_cc termios data copied correctly.  Also moved the allocation
274    of the string to avoid problems if it caused a GC.
275    
276    Thanks to Timothy Bourke for the bug report and fix.

280    Date: 2006/12/08 09:50:00 CST
281    Description:
282    
283    Added code to CM's "standard shell tool" implementation which
284    causes it to tolerate (with a warning) the situation where the shell
285    command fails (e.g., due to the shell command's non-existence)
286    as long as all target files exist.
287    
288    This makes it possible to, e.g., build ml-yacc from sources even if
289    svn checkout messed up the time stamps on files in such a way that
290    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
291    be needed to re-process yacc.grm, but obviously it might not yet be
292    available at that time.)

298    
299    Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
300    recvVecFromNB' in the SOCKET signature.  This error is actually
301    in the SML Basis specification too.

307    
308    CM now reports undefined anchors as errors and aborts execution
309    rather than silently pressing on using bogus values.

315    
316    Use Say.vsay for printing the "[autoloading]" message, so

331    Tag: release-110.60
332    Description:
333    
334    New working release (110.60).  NEW BOOTFILES!
335    
336    This is the first subversion-hosted release.  There are also changes
337    to the directory layout.  Here is a table:
338    
339    (All pathnames are relative to the SML/NJ "root" directory.)
340    
341      config -> config
342    
343      src/cm -> base/cm
344      src/compiler -> base/compiler
345      src/runtime -> base/runtime
346      src/system -> base/system
347    
348      src/cm/pgraph -> pgraph
349    
350      src/READMES -> base/READMES
351      src/$notefile -> base/NOTES/$notefile
352         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
353                           MACOSXINSTALL WININSTALL
354    
355      src/smlnj-lib -> smlnj-lib
356      src/MLRISC -> MLRISC
357      ckit -> ckit
358      src/cml -> cml
359      src/eXene -> eXene
360      src/heap2asm -> heap2asm
361      src/lexgen -> lexgen
362      src/ml-burg -> ml-burg
363      src/ml-lex -> ml-lex
364      src/ml-yacc -> ml-yacc
365      src/ml-nlffi-lib -> nlffi/lib
366      src/ml-nlffigen -> nlffi/gen
367      src/smlnj-c -> smlnj-c
368      src/tools/TraceDebugProf -> trace-debug-profile
369    
370    In addition, there is also a new
371    
372      ml-lpt
373    
374    directory containing two new program generator tools: ml-ulex and
375    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
376    LL(k) parser generator). These tools are currently "beta-quality"
377    
378    The latest versios of the sources can now be obtained anonymously
379    via subversion.  For this, it is useful to first check out
380    
381       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
382    
383    and put the resulting directory on your shell's PATH.  This provides
384    access to three shell scripts: checkout-all.sh, stat-all.sh,
385    and refresh-all.sh.
386    
387    To create a freshly checked-out copy of the sources, do
388    
389       checkout-all.sh [dir]
390    
391    where dir is the optional SML/NJ root directory (default is ".").
392    
393    This creates the above directory layout.  Each subdirectory of
394    the root is under individual subversion control.  The stat-all.sh
395    and refresh-al.sh scripts apply "svn stat" or "svn update" to
396    each of these subtrees.
397    
398    ----------------------------------------------------------------------
399    Name: Matthias Blume (http://www.tti-c.org/blume/)
400    Date: 2006/11/02 12:20:00 CST
401    Description:
402    
403    Reorganized directory layout.
404    
405    This is a temporary solution, more reorganization is to come.
406    
407    The basic idea is to have a number of toplevel trees, each corresponding
408    to a well-defined part of the overall system.  Each part can be
409    maintained individually, even in separate source repositories,
410    although currently we still serve everything out of the main
411    smlnj-gforge tree.
412    
413    Installer and and scripts have been updated to reflect the new
414    layout.  The installer (base/src/system/smlnj/installer) is now
415    "scriptable" to avoid burning too much knowledge about the
416    layout into SML source code.  The main script used by the installer
417    is in config/actions.
418    
419    The main change is that many of the subdirectories of what used to
420    be known as "src" have moved to the toplevel.  The "src" directory
421    itself has moved down into a subtree called "base".  (We may eventually
422    get rid of the extra level of indirection represented by "src".)
423    
424    The layout is now as follows:
425    
426      toplevel tree name | default repository
427                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
428      -------------------+----------------------------------------------------
429      config             | $gf/config/trunk
430                         |
431      base               | $gf/sml/trunk
432                         |
433      smlnj-lib          | $gf/smlnj-lib/trunk
434      MLRISC             | $gf/MLRISC/trunk
435                         |
436      ml-yacc            | $gf/ml-yacc/trunk
437      ml-lex             | $gf/ml-lex/trunk
438      ml-burg            | $gf/ml-burg/trunk
439      lexgen             | $gf/lexgen/trunk
440      heap2asm           | $gf/heap2asm/trunk
441                         |
442      cml                | $gf/cml/trunk
443      eXene              | $gf/eXene/trunk
444      ckit               | $gf/ckit/trunk
445      nlffi              | $gf/nlffi/trunk
446                         |
447      smlnj-c            | $gf/smlnj-c/trunk
448    
449    In $gf/admin there are a few useful shell scripts for checking out
450    and maintaining the entire collection of trees:
451    
452       admin/checkout-all.sh [dir]
453          -- optionally creates dir and checks out all trees from their
454             default repositories; if dir is missing, checkout into .
455       admin/refresh-all.sh [dir]
456          -- looks at all trees (from the above list) in dir (default: .)
457             and runs "svn update" if the tree exists and is under
458             subversion control;
459             non-existing or non-subversion trees are skipped
460       admin/stat-all.sh [dir]
461          -- like refresh-all.sh, but runs "svn stat" instead

477    
478    New working version (110.59).  NEW BOOTFILES!
479    
480    I am freezing 110.59.  Changes other than the version-number increase:
481    
482      eXene:
483    
484         * committed changes to eXene from Alley Stoughton:
485             "fixed bugs in X authorization and resource handling, as well
486              as in the pile and viewport widgets"
487    
488      Runtime:
489        * fixed linking problem with NetBSD 3.x.
490    
491      Lexgen:
492        * lexgen tool handles non-ascii characters in 7-bit mode the same
493          way that ml-lex does
494    
495        * lexgen propagates exceptions the same way that ml-lex does
496    
497      CML:
498        * Fixed a bug in the SyncVar polling functions (iGetPoll,
499          mTakePoll, and mGetPoll) that could lead to livelock.

505    Description:
506    
507    Implemented ml-makedepend (i.e., CM.sources) in a better (more robust)
508    way.  This should hopefully fix the ml-makedepend problem permanently.

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

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

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

641    Description:
642    
643    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
644    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
645    at the time when config/preloads is processed, the library has to
646    be referred to by another name.  In 110.57 this would be
647    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
648    to be valid as well.)
649    
650    Thanks to Todd Wilson (Fresno) for alerting me to this issue.

703    Tag: blume-22051115-versiontool
704    Description:
705    
706    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
707    file gets loaded as a tool -- by the equivalent of CM.make during the
708    run of CMB.make.  Thus, CMB's path configuration is meaningless for
709    it.  Instead, it has the status of "user code", so it should use
710    $/basis.cm to refer to the Basis library.  (At least that's true for
711    the purpose of bootstrapping the previous change.  In the future it
712    might make sense to have versiontool.cm refer to
713    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
714    compiler itself uses.)
715    
716    Also patched src/system/testml to have it activate those extra anchor
717    bindings in config/extrapathconfig.

722    Tag: blume-22051115-libraries
723    Description:
724    
725    This change affects the way the following libraries are tied into
726    the system:
727    
728       $/basis.cm
729       $/smlnj-lib.cm
730       $/pp-lib.cm
731       $/controls-lib.cm
732       $/html-lib.cm
733       $/ml-yacc-lib.cm
734    
735    These libraries are now internally (as seen from the source code
736    of the implementation itself) known by the following names:
737    
738       $smlnj/basis/basis.cm
739       $smlnj/smlnj-lib/smlnj-lib.cm
740       $smlnj/smlnj-lib/pp-lib.cm
741       $smlnj/smlnj-lib/controls-lib.cm
742       $smlnj/smlnj-lib/html-lib.cm
743       $smlnj/ml-yacc/ml-yacc-lib.cm
744    
745    This makes it possible to work with code that requires different
746    versions of these libraries, and which refers to these libraries using
747    their "default" names (i.e., the first set of names above).  In other
748    words, one can un-define or re-define those default names without
749    compromising the proper functioning of the compiler itself.
750    
751    A similar procedure had already been performed for several of the
752    MLRISC libraries that are linked into the compiler.  I did some
753    cleanup on this code.
754    
755    A new file in the config directory (named extrapathconfig) is
756    responsible for setting up path anchors that the compiler itself does
757    not need, but that are typically required by user code.

936    Tag: blume-20050516-redump-heap
937    Description:
938    
939    Added mechanism for re-creating a heap file for the interactive system
940    after configuration variables have been changed.
941    
942       CM.redump_heap : string -> unit
943    
944    This is much like SMLofNJ.exportML, but starting from the resulting
945    heap does not return to the caller of CM.redump_heap but
946    restarts the interactive system from scratch.  The original call of
947    CM.redump_heap does not return but ends the interactive session.
948    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
949    
950    Internally, redump_heap winds the dynamic execution context back to
951    the point where the original heap image was created and re-executes
952    the heap image generation code in the boot code.

1068    Tag: blume-20050114-heap2exec
1069    Description:
1070    
1071    Implemented new (but still experimental) heap2exec facility.  This is
1072    tested under Mac OS X and should work under Linux (will test shortly).
1073    It will probably also work on the Sparc (will test some time later).
1074    
1075      - removed old "HACKED_STANDALONE" hack from runtime
1076    
1077    To be able to test this, uncomment the request for "heap2asm" in
1078    config/targets prior to installation.  (Notice that this is different
1079    from "heap2exec" mentioned below.  Not a typo.)
1080    
1081    To perform an actual test, run the command
1082    
1083       $ bin/heap2exec heapfile execfile
1084    
1085    (You can put heap2exec on your shell's path.)
1086    
1087    For example, run
1088    
1089      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1090    
1091    This will create a standalone executable called "mly" which you can
1092    then invoke directly as a command.

1237    Tag: blume-20041124-position
1238    Description:
1239    
1240    The compiler can now be compiled in a mode that makes structure Position
1241    equal to Int64.  The default, however, is unchanged (Position = Int31)
1242    for the time being.
1243    
1244    To enable 64-bit positions, use the following procedure:
1245    
1246    1. Start sml
1247    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1248    3. Type
1249          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1250    4. Run CMB.make() as usual.
1251    
1252    This is barely tested.  The only test so far was a little SML program
1253    counting the number of characters in an 8-gigabyte file by
1254    reading it character-by-character.  That test was successful.
1255    
1256    In support of 64-bit positions, a number of new functions have been
1257    added to the runtime system.

1302    
1303    - In a previous commit, fixed a minor issue with how polyequal is being
1304      translated.  In particular, the code now "looks through" abstractions.
1305      This results in slightly fewer polyEqual warnings and hopefully slightly
1306      more efficient code.  Important examples for where this matters are
1307      the new int64 and word64 types.

1326    but for the time being they don't even make sense because LargeWord is
1327    32-bit wide.)
1328    
1329    Also started to add similar support for Int64, but major pieces of that
1330    are still missing.

1336    Description:
1337    
1338    Structure Word64 is now (almost) complete, word literals and patterns
1339    seem to work.  There are a few odd pieces missing.  In particular,
1340    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1341    at the moment.
1342    
1343    Making Word64 official would mean that LargeWord becomes Word64.  But
1344    this requires extreme care because most word-word conversions have to
1345    go through LargeWord, so making a mistake means loss of efficiency or
1346    worse.  Eventually there will be a solution similar to (but actually
1347    simpler than) what I did with IntInf.

1372    
1373    New working version (110.50).  NEW BOOTFILES!
1374    
1375                 =====================
1376    
1377    Also:
1378    
1379      - Changend config/srcarchiveurl from a file just
1380        containing the URL string into a file containing
1381        shell script code.  The code has access to the $VERSION variable.
1382      - Made corresponding changes to config/install.sh and config/unpack.
1383      - Default contents of config/srcarchiveurl uses $VERSION and
1384        normally does not have to be edited to reflect a version change.
1385    
1386      (As a result, a version change can be done by just editing
1387       config/version, the rest is now automatic.)

1408      - made sure the caller does not add the wrong number of bytes to the
1409        stack pointer after a call of a function returning a struct
1410        (the callee already pops the implicit argument which points to
1411         the space reserved for the result)

1427    Tag: blume-20041020-standalone-backtrace
1428    Description:
1429    
1430    Added a mechanism for getting back-trace information from standalone
1431    programs.  Here is how it works:
1432    
1433       1. The part of the program from which you want to get backtrace
1434          information (usually the whole program) should be wrapped with
1435          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
1436          main program could be modified from something like
1437    
1438             fun main (pgm, args) = ...
1439    
1440         to
1441    
1442            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1443    
1444       2. To be able to access BackTrace.monitor, you have to add
1445          library $smlnj-tdp/plugins.cm to the .cm file that contains your
1446          main function.
1447    
1448       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1449          CM might have created in the past for your project).
1450    
1451       4. Build the system using this command line:
1452    
1453             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1454                      myprog.cm MyProg.main myprog
1455    
1456          instead of the usual
1457    
1458             ml-build myprog.cm MyProg.main myprog
1459    
1460    I changed a library name:
1461    
1462       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1463    
1464    New libraries:
1465    
1466       $smlnj-tdp/back-trace.cm
1467          -- when loaded causes the back-trace plugin to be installed
1468       $smlnj-tdp/coverage.cm
1469          -- when loaded causes the coverage plugin to be installed

1485    Description:
1486    
1487    * Test coverage tool added!
1488    * Further reorganization of tracing-, debugging-, and profiling support:
1489    
1490        - moved original BTImp -- now called BackTrace -- into a separate
1491          library called $/trace-debug-profile.cm
1492        - eliminated all mentions of BTrace from SMLofNJ.Internals
1493        - only the instrumentation mechanism is now left in the compiler proper
1494        - BackTrace module is a plugin which is NOT plugged in by default
1495        - Coverage module is another such plugin
1496    
1497    To get the benefits of any of these plugin modules, the code in
1498    question must be compiled with tdp instrumentation turned on.  This
1499    can be done by setting SMLofNJ.Internals.TDP.mode to true.
1500    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1501    
1502    Plugins are selected at link time.  (Pre-compiled instrumented code
1503    can be re-loaded with different plugins in effect.)  When an
1504    instrumented module is linked, whatever plugins are at that time
1505    enabled will come into effect for that module.
1506    
1507    To enable the back-trace plugin, load library $/trace-debug-profile.cm
1508    and invoke BackTrace.install() (e.g., from the interactive prompt).
1509    To enable the coverage plugin, load the same library and invoke
1510    Coverage.install().
1511    
1512    Back-traces are generated automatically on uncaught exceptions and
1513    when the code in question explicitly invokes BackTrace.trigger().
1514    
1515    Coverage (and execution frequency-) information must be queried
1516    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

1533    Some rationalization of names:

1536       etc.
1537    
1538    This is is preparation of using the original back-trace
1539    instrumentation for other purposes.  "TDP" stands for
1540    Trace/Debug/Profile.
1541    
1542    The control flag controlling whether instrumentation is on or off is now
1543    registered under a different name, so instead of running sml as
1544    
1545     sml -Cinstrument.btrace-mode=true
1546    
1547    one has to say
1548    
1549     sml -Ctdp.instrument=true

1565    Description:
1566    
1567    Fixed handling of keywords in .cm files: After seeing "is" the lexer
1568    treats subsequent occurrences of "group", "library", "source", "is",
1569    "*", and "-" as ordinary identifiers rather than keywords.
1570    
1571    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
1572    is supposed to accept a tool argument called "source", but this did
1573    not work because of the clash with the keyword.

1616    Description:
1617    
1618    * Moved the "version" magic into its own little library under
1619      src/system/smlnj/internal.  This avoids expensive reconstruction of
1620      a stable src/compiler/core.cm.
1621    
1622    * At the same time, structure CompilerVersion is now known as
1623      structure SMLNJVersion.
1624    
1625    * Arranged for the version tool to NOT kick in when rebuilding the system
1626      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
1627      Also, loading the versiontool does not work when rebuilding the system
1628      because CM is not properly initialized at that time.

1633    Tag: blume-20040929-autoversion
1634    Description:
1635    
1636    Implemented some CM magic to have
1637        file src/compiler/TopLevel/main/version.sml
1638    generated automagically.
1639    The version is taken from two files: config/version and config/release.
1640    The first is expected to contain a two-part version number such as 110.49.
1641    The second should contain a single number, but it may be missing.
1642    
1643    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
1644    time the version tool is loaded (which is the first time you say CMB.make),
1645    then the tool will increment the value stored in config/release every
1646    time CMB.make is invoked.
1647    
1648    The binfile format is now insensitive to anything beyond the first
1649    two components of a version number, so bumping the release does not render
1650    binfiles incompatible.  Auto-bumping can be used to keep track of versions
1651    during development without invalidating existing binfiles.
1652    
1653    In any case, every CMB.make updates the date information in version.sml.
1654    (This is the date that is printed in the banner.)

1667    Tag: blume-20040927-controls
1668    Description:
1669    
1670    Added two pieces of functionality to the Controls interface:
1671    
1672    1.   val save'restore: 'a control -> unit -> unit
1673    
1674       grabs the current value of the control in stage 1 and restores it
1675       in stage 2.
1676    
1677    2.   val set' : 'a control * 'a -> unit -> unit
1678    
1679       stores the given value into the control in stage 2 (i.e., delayed)
1680       but does all error checking in stage 1.
1681       (This is for string controls that need to do parse their argument --
1682        something that might fail.  In some cases, notably in CM, one
1683        already knows the intended argument but wants to delay the actual
1684        assignment until a time when error recovery would be more difficult.)
1685    
1686    Changed the handling of controls in tool arguments to classes "sml" and
1687    "lazysml":
1688       - use Controls.save'restore as a more robust way of restoring the
1689         old value (in particular: without having to re-parse the string)
1690       - use controls to handle the "overload" keyword in the init group
1691         (I believe this change actually fixes a long-standing obscure bug.)

1696    Tag: blume-20040927-lazysml
1697    Description:
1698    
1699    Added a new tool class called "lazysml" to CM's tool chest.  The only
1700    difference to "sml" is that compilation is done with Control.lazysml
1701    set to true.  A source of class "lazysml" is automatically recognized
1702    by a file name suffix of ".lml".
1703    
1704    In addition to the above feature, the original class "sml" now also
1705    supports a tool argument "lazy" which has the same effect.  As a
1706    result, the following three lines are equivalent:
1707    
1708        foo.sml : lazysml
1709        foo.sml : sml (lazy)
1710        foo.sml (lazy)
1711    
1712    The setting goes into effect both during parsing and during
1713    compilation.  The original setting is restored right after parsing and
1714    after compilation, respectively.
1715    
1716    In addition to all the above, there is also a general mechanism to set
1717    ANY of the "controls" that are available at the command line via
1718    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
1719    apply as well. (In fact, "lazy" is implemented as a special case of
1720    the general mechanism.)
1721    
1722    The .cm file syntax uses a new keyword tool argument called "with".
1723    There are several ways of indicating the desired settings:
1724    
1725        foo.sml (with:parser.quotations=true)
1726        foo.sml (with:(name:parser.quotations value:true))
1727        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
1728        foo.sml (with:(name1=value1 name2=value2 ...))
1729        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
1730    
1731        etc.
1732    
1733    Another possible abbreviation is to leave out the =v or value:v part
1734    if the name refers to a boolean control (in which case the value is
1735    taken to be true).  Thus, one could get lazy sml also by saying:
1736    
1737        foo.sml (with:parser.lazy-keyword=true)
1738        foo.sml (with:parser.lazy-keyword)
1739        foo.sml (with:(name:parser.lazy-keyword value:true))
1740        foo.sml (with:(name:parser.lazy-keyword))

2092    Description:
2093    
2094    Changed the interface of structures Timer and Unix to match the most
2095    recent Basis spec.
2096    
2097    In the case of Unix there still seems to be an open/weird issue:
2098    
2099       The {text,bin}{In,Out}streamOf functions are supposed to create
2100       fresh streams whenever they are called -- as opposed to have them
2101       return the same stream every time.  This design is supposed to
2102       prevent space leaks caused by proc values hanging on to streams.
2103    
2104       The reap function, on the other hand, is supposed to close the
2105       streams.  This cannot be done without having a handle on the
2106       stream in proc after all...
2107    
2108    I took the liberty to implement the following stopgap solution:
2109    
2110      The proc value hangs on to the most recently created stream(s).
2111      Reap closes those.  If either or both of the two streams hadn't
2112      been created at all yet, then reap will close the corresponding
2113      file descriptors directly.
2114    
2115    PS: I don't understand the original space leak argument anymore.  If
2116    a proc hangs on to the imperative stream, then I/O operations on those
2117    will advance the state of the cached stream and avoid the space leak.

2131    Description:
2132    
2133    CM now ignores (but still accepts) the "owner" information in group
2134    descriptions.  The owner of a group is its next enclosing
2135    library. Each group must have a unique owner.  (There is a virtual
2136    "toplevel" library that owns groups which are not nested within a real
2137    library.)  Previously, each group had to explicitly declare its owner,
2138    and CM would check that such a declaration is correct.  The new scheme
2139    is to have CM check that for each group there is precisely one owning
2140    library.
2141    
2142    The advantage of the new scheme is that the programmer no longer needs
2143    to maintain the somewhat annoying owner information.  The downside is
2144    that CM cannot enforce the ownership rule across multiple runs of
2145    CM.make.  Fortunately, enclosing the same group in two different
2146    libraries A and B which are not part of the same program does not
2147    cause real problems.

2166    Description:
2167    
2168    Arranged for ml-build to clean up after itself a little bit better.
2169    The script generates a temporary SML source file and compiles it using
2170    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
2171    gets rid of those at the end, so they don't accumulate under .cm.
2172    
2173    This required a minor change to install.sh because the name of the
2174    metadata directory (default: .cm) is actually configurable at
2175    installation time.

2192    Added previously missing support for many socket-related functions
2193    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
2194    for the voluminous patch!
2195    
2196    (I have not tested this patch under win32 yet.)
2197    
2198    Here is David's e-mail:
2199    
2200    Hi,
2201    
2202    Attached to this email you find a diff against sml/nj 110.45
2203    that will enable socket support under Windows.
2204    
2205    To apply the patch (using unix or cygwin)
2206    1) gunzip runtime.diff.gz
2207    2) "cd" into "src/runtime" in the source tree of a fresh
2208       110.45 installation.
2209    3) patch -p 1 < [your/path/to]runtime.diff
2210    
2211    The code compiles fine but has NOT yet been extensively tested.
2212    I only ran a few tests for basic socket client functionality
2213    (which worked fine).  Especially the functions that use ioctl
2214    are not tested at all and might not work (see below).
2215    
2216    I implemented this since we want to move to a newer version of sml/nj
2217    but need socket support in order to use it.  This is the first time I
2218    even had a look at the sml/nj source,  so please review my changes
2219    before making this part of the distribution!  Here are a few issues
2220    that I think might be better for someone to solve who is more
2221    familiar with the sml/nj source (and socket programming):
2222    
2223    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2224      exception since I could not figure out what the windows equivalent
2225      of these functions is
2226    
2227    - In sockets-osdep.h there are a some #include statements that are
2228      only used in a few files that include sockets-osdep.h
2229    
2230    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2231      does not process its return value since I don't know how to
2232      report an error upwards.
2233    
2234    - It would probably be good to have a call to WSACleanup() when
2235      the library is unloaded (if there is such a possibility).
2236      Otherwise I think Windows will take care of this automatically
2237      when the process finishes.
2238    
2239    - I used ioctlsocket() as a replacement for ioctl() but I have
2240      no idea if that is actually the proper replacement on Windows.
2241    
2242    - All these issues are marked in the code by "FIXME" comments.
2243    
2244    We use sml/nj extensively in our products and are quite happy
2245    with it.  I hope this contribution will help you.
2246    
2247    Keep up the good work!

2284    The installer now honors the "src-smlnj" target again, although its meaning
2285    has changed from "all sources required for the compiler" to "all sources
2286    the installer knows about".  In other words, if you enable "src-smlnj"
2287    in the "targets" file, then the installer will pull in sources for
2288    everything.  (Notice that this refers to source code only.  Compiled
2289    code is still only installed for modules that were requested explicitly
2290    or which are required for other modules that were requested explicitly.)

2324    Description:
2325    
2326    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
2327    of SML/NJ.  The problem is that
2328    
2329       lib = dlopen(NULL, ...)
2330       f   = dlsym(lib, "malloc");
2331    
2332    does not work on Windows unless we explicitly export symbols
2333    such as 'malloc' during linking.  We fixed this by explicitly
2334    exporting the required symbols with the magic gcc incantation:
2335    
2336        -Wl,--export-all cygwin.def
2337    
2338    where cygwin.def is a file containing all the symbols that
2339    we wish to export.
2340    
2341    I suspect this is a Windows problem and we'll have to
2342    do the same (somehow with windows compilers) when
2343    we build the native win32 version with the system
2344    calls LoadLibrary/GetProcAddress.

2415    (The mechanism was broken and could not be fixed easily.  Moreover,
2416    there does not seem to be any reason not to move all libraries into
2417    lib during installation.  I originally implemented this directive as a
2418    backward-compatibility feature when I first introduced the new CM.
2419    Now that things have been stable for a long time and going back to the
2420    old CM is not an option, there is no reason to keep it around.)

2469    Tag: blume-20030926-ppautoload
2470    Description:
2471    
2472    I modified the read-eval-print loop so that the autoloader gets
2473    invoked whenever the prettyprinter tries to look up a symbol that
2474    is not currently defined in the toplevel environment but which
2475    appears in CM's autoload registry.  As a result, we see far fewer of
2476    those ?.Foo.Bar.xxx names in the prettyprinter's output.
2477    
2478    In addition to this I tried to clean up some pieces of the Basis
2479    implementation (e.g., Socket, Word8Array) in order to prevent other
2480    instances of these ?.Foo.Bar.xxx names from being printed.
2481    
2482    The mechanism that picks names for types still needs some work, though.
2483    (Right now it seems that if there is a type A.t which is defined to
2484    be B.u, but B is unavailable at toplevel, then A.t gets printed as
2485    "?.B.u" although the perhaps more sensible solution would be to use
2486    "A.t" in this case.  In other words, the prettyprinter should follow
2487    a chain of DEFtycs not farther than there are corresponding toplevel
2488    names in the current environment.)

2494    Description:
2495    
2496    Another installer tweak:  All the ML code for the installer is now
2497    compiled during CMB.make and put into a little library called
2498    $smlnj/installer.cm.  The installation then simply invokes
2499    
2500       sml -m $smlnj/installer.cm
2501    
2502    and everything happens automagically.
2503    
2504    Win32:  ML code senses value of environment variable SMLNJ_HOME.
2505    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
2506            and BINDIR.
2507    
2508    The new scheme guarantees that the ML code responsible for the installation
2509    is in sync with the APIs of the main system.  Also, the installer is
2510    somewhat faster because the installer script is precompiled.

2521    implementations of non-blocking operations from CML's Socket
2522    structure.

2527    Tag: blume-20030924-sockets
2528    Description:
2529    
2530    1. Fixed SOCKET API and implementation to match Basis spec.
2531       This required changing the internal representation of sockets to one
2532       that remembers (for each socket file descriptor) whether it is currently
2533       blocking or non-blocking.  This state is maintained lazily (i.e., a system
2534       call is made only if the state actually needs to change).
2535    
2536    2. OS-specific details of sockets were moved into separate files, thus
2537       making it possible to unify the bulk of the socket implementations
2538       between Unix and Win32.
2539    
2540    3. CML's socket API changed accordingly.
2541       (Note that we need to remove non-blocking functions from this API
2542       since they are redundant in the case of CML!)
2543    
2544    4. CML's socket implementation now makes use of non-blocking functions
2545       provided by Basis, thus removing all OS-dependent code from this part
2546       of CML.
2547    
2548    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

2661    Description:
2662    
2663    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
2664    Modified config/install.bat to take advantage of it.  Also modified
2665    config/install.sh (and called it config/new-install.sh) to take advantage
2666    of it on Unix systems.  (The SML code is (supposed to be) platform-
2667    independent.)
2668    
2669    The installer can now install everything under Win32
2670    as well as under *nix as long as it compiles.
2671    
2672    Other changes:
2673    
2674      - made CML compile again under Win32
2675      - made eXene compile under Win32 (by providing a fake structure UnixSock
2676        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
2677      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
2678        same as type int;  under Win32 it isn't
2679      - fixed some slice-related problems in the win32-specific parts of CML
2680      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
2681        (under Win32, the volume name is case-insensitive, and the
2682        OS.Path code compares volume names for equality)

2688    Description:
2689    
2690    Made Win32 version of OS.FileSys.fullPath return current directory
2691    when given an empty string.  This is what the spec says, and incidentally,
2692    CM depends on it.  (CM otherwise goes into an infinite loop in certain
2693    cases when presented with the name of a non-existing .cm file.)

2699    Description:
2700    
2701      1. Changed interface to vectors and arrays in Basis to match
2702         (draft) Basis spec.
2703      2. Added signatures and implementations of slices according to
2704         Basis spec.
2705      3. Edited source code throughout the system to make it compile again
2706         under 1. and 2.  (In some cases code had to be added to have it
2707         match the new signatures.)
2708      4. MLRISC should be backward-compatible: the copies of the originals
2709         of files that needed to change under 3. were retained, the .cm files
2710         check the compiler version number and use old versions when
2711         appropriate.
2712      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
2713         dirstream -> string option (in accordance with Basis spec).
2714      6. When generating code that counts lines, ml-lex used function
2715         CharVector.foldli, taking advantage of its old interface.
2716         This has been replaced with the corresponding code from
2717         CharVectorSlice.  (html-lex must be re-lexed!)
2718      7. BitArray in smlnj-lib/Util has been extended/modified to match the
2719         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
2720      8. Removed temporary additions (fromInternal, toInternal) from the
2721         (now obsolete) IntInf in smlnj-lib/Util.
2722      9. Cleaned up structure Byte.
2723     10. Added localOffset, scan, and fromString to Date (according to spec).
2724         Cleaned/corrected implementation of Date.
2725         (Still need to check for correctness; implement better canonicalizeDate.)
2726     11. Added "scan" to signature IEEE_REAL.
2727     12. Some improvements to IntInf [in particular: efficiency-hack for
2728         mod and rem when second operand is 2 (for parity checks).]
2729     13. Changed representation of type Time.time, using a single IntInf.int
2730         value counting microseconds.  This considerably simplified the
2731         implementation of structure Time.  We now support negative time
2732         values; scan and fromString handle signs.
2733     14. Functor PrimIO now takes two additional arguments (VectorSlice and
2734         ArraySlice).

2740    Description:
2741    
2742    This is a major update which comes with a version number bump
2743    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
2744    and an implementation of IntInf in the Basis.
2745    
2746    There are a fairly large number of related changes and updates throughout
2747    the system:
2748    
2749    Basis:
2750            - Implemented IntInf.
2751            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
2752            - Added some missing Real64 operations, most notably Real.toLargeInt.
2753            - Added FixedInt as a synonym for Int32.
2754    
2755    compiler:
2756            * Added support for a built-in intinf type.
2757              - literals
2758              - pattern matching
2759              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
2760              - overloading on literals and operations
2761    
2762            This required adding a primitive type intinf, some additional
2763            primops, and implementations for several non-trivial intinf
2764            operations in Core.  (The intinf type is completely abstract
2765            to the compiler; all operations get delegated back to the Core.)
2766    
2767            * Intinf equality is handled by polyequal.  However, the compiler
2768            does not print its usual warning in this case (since polyequal
2769            is the right thing to do there).
2770    
2771            * Improved the organization of structure InlineT.
2772    
2773            * A word about conversion primops:
2774            If conversions involving intinf do not cancel out during
2775            CPS contract, then the compiler must insert calls to Core functions.
2776            Since all core access must be resolved already during the FLINT
2777            translate phase, it would be too late a the time of CPS contract
2778            to add new Core calls.  For this reason, conversion primops
2779            for intinf carry two arguments:  1. the numeric argument that
2780            they are supposed to convert, and 2. the Core function that
2781            can help with this conversion if necessary.  If CPS contract
2782            eliminates a primop, then the associated Core function becomes
2783            dead and goes away.  Intinf conversion primops that do not get
2784            eliminated by CPS contract get rewritten into calls of their
2785            core functions by a separate, new phase.
2786    
2787    interactive system:
2788            - Control.Print.intinfDepth controls max length of intinf constants
2789            being printed. (Analogous to Control.Print.stringDepth.)
2790            - Cleanup in printutil and pputil: got rid of unused stuff and
2791            duplicates; replaced some of the code with code that makes better
2792            use of library functionality.
2793    
2794    CM:
2795            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
2796            are no longer silent.
2797    
2798    CKIT:
2799            Fixed mismatched uses of Int32 and LargeInt.  I always decided
2800            in favor of LargeInt -- which is now the same as IntInf.
2801            CKIT-knowledgable people should check whether this is what's
2802            intended and otherwise change things back to using Int32 or
2803            FixedInt.
2804    
2805    Throughout the code:
2806            Started using IntInf.int literals and built-in operations
2807            (e.g., comparison with 0) where this seems appropriate.

2819    of a couple of bugs (895, 1186) relating to error messages.  A new

2827    Description:
2828    
2829    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
2830    
2831        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
2832    
2833    This patch restores SML/NJ's ability to run under win32.  There are a
2834    number of changes, including fixes for several bugs that had gone
2835    unnoticed until now:
2836    
2837      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
2838        trying to run the win32 version from within cygwin.)
2839    
2840      - There are a number of simple .bat scripts that substitute for their
2841        corresponding Unix shell-scripts.  (See below.)
2842    
2843      - The internals of ml-build have been modified slightly.  The main
2844        difference is that instead of calling ".link-sml" (or link-sml.bat)
2845        using OS.Process.system, the ML process delegates this task back
2846        to the script.  Otherwise problems arise in mixed environments such
2847        as Cygwin where scripts look and work like Unix scripts, but
2848        where OS.Process.system cannot run them.
2849    
2850      - In CM, the srcpath pickler used native pathname syntax -- which
2851        is incorrect in the case of cross-compilation.  The new pickle format
2852        is independent of platform-specific naming conventions.
2853    
2854      - Path configuration files (such as lib/pathconfig) can now choose
2855        between native and standard syntax.  Placing a line of the form
2856    
2857            standard!
2858    
2859        into the file causes all subsequent paths to be interpreted using
2860        CM standard pathname syntax (= Unix conventions); a line
2861    
2862            native!
2863    
2864        switches back to native style.  This was needed so that
2865        path config files can be written portably, see src/system/pathconfig.
2866    
2867      - Runtime system:
2868    
2869          - win32-filesys.c:  get_file_time and set_file_time now
2870            access modification time, not creation time.
2871    
2872          - I/O code made aware of new array representation.
2873    
2874          - Bug fixes in X86.prim.masm.
2875    
2876       - src/system/makeml made aware of win32. (For use under cygwin
2877            and other Unix-environments for windows.)
2878    
2879       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
2880         which caused BinIO.inputAll to fail consistently.
2881    
2882    .bat scripts:
2883    
2884       Windows .bat scripts assume that SMLNJ_HOME is defined.
2885    
2886       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
2887         applications (sml, ml-yacc, ml-lex).
2888       - ml-build.bat: analogous to ml-build.
2889       - config\install.bat:  Analogous to config/install.sh.  This requires
2890         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
2891         (nmake etc. must be on the path, and vcvars32 must have been run.)
2892         Moreover, sources for ml-lex and ml-yacc need to exist under src,
2893         and the bootfile hierarchy must have been unpacked under
2894         sml.boot.x86-win32.
2895         The script is very primitive and does a poor job at error checking.
2896         It only installs the base system, ml-lex, and ml-yacc.  No other
2897         libraries are being installed (i.e., you get only those that
2898         are part of the compiler.)
2899       - link-sml.bat:  analogous to .link-sml, but not currently used
2900    
2901    Unrelated bug fixes:
2902    
2903      - ml-nlffigen now exports structures ST_* corresponding to incomplete
2904        types.
2905      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
2906        otherwise.)

2932    Two changes:

2934      1. Added a flag for controlling whether non-exhaustive bindings will
2935         be treated as errors (default is false).
2936      2. Cleaned up the *entire* source tree so that CMB.make goes through
2937         without a single non-exhaustive match- or bind warning.

2943    Description:
2944    
2945    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
2946    
2947       This mainly affects the quality of error messages.  However, some
2948       of the code is now more straightforward than before. (Treatment of
2949       the above four constructs in translate.sml is much simpler than
2950       the "macro-expansion" that was going on before.  Plus, the mach-
2951       compiler no longer gets invoked just to be able to compile an
2952       if-expression.)
2953    
2954    2. The ErrorMsg.Error exception is now caught and absorbed by the
2955       interactive loop.

2961    Description:
2962    
2963        Ported the runtime system to cygwin, which uses the unix
2964    x86-unix bin files.  Missing/buggy features:
2965    
2966       o getnetbyname, getnetbyaddr: these functions seem to be missing in
2967         the Cygwin library.
2968       o Ctrl-C handling may be flaky.
2969       o Windows system calls and Windows I/O are not supported.
2970    
2971       A new set of binfiles is located at:
2972    
2973         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
2974    
2975       This is only needed for bootstrapping the cygwin version of smlnj.
2976       Other x86 versions can use the existing binfiles.

3006    110.37 and 110.38.)
3007    There was another set of potential problems related to the handling of
3008    MLRISC annotations (but those did not yet cause real problems, apparently).

3035    
3036    In good old tradition, there has been a slight hiccup so that we have
3037    to patch 110.42 after the fact.   The old release tag has been replaced
3038    (see below).
3039    
3040    The change solves a problem with two competing approaches the
3041    configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
3042    each other's way.
3043    
3044    This change only affects the runtime system code and the installer script.

3061    The mltree operator DIVS must be implemented with an overflow check on
3062    the PPC because the hardware indicates divide-by-zero using "overflow" as
3063    well.

3070    
3071    Sml now senses the SMLNJ_HOME environment variable.  If this is set,
3072    then the bin dir is assumed to be in $SMLNJ_HOME/bin and (unless
3073    CM_PATHCONFIG is also set), the path configuration file is assumed
3074    to be in $SMLNJ_HOME/lib/pathconfig.  This way one can easily move
3075    the entire tree to some other place and everything will "just work".
3076    
3077    (Companion commands such as ml-build and ml-makedepend also sense this
3078    variable.)

3111    Fixed a bug in translation of INLMAX (and INLMIN) for the floating-point
3112    case.  (The sense of the isNaN test was reversed -- which made min and
3113    max always return their first argument.)

3127    Description:
3128    
3129    I back-ported my implementation of IEEEReal.fromString from the
3130    idlbasis-devel branch so that we can test it.
3131    
3132    Another small change is that ppDec tries to give more information
3133    than just "<sig>" in the case of functors.  However, this code is
3134    broken in some mysterious way if the functor's body's signature
3135    has not been declared by ascription but gets inferred from the
3136    implementation.  This needs fixing...

3199    
3200    - Added ControlUtil structure to control-lib.cm.
3201    - Use it throughout.
3202    - Used Controls facility to define MLRISC controls (as opposed to
3203      registering MLRISC control ref cells with Controls after the fact)
3204    - Fixed messed-up controls priorities.
3205    
3206    * Removed again all the stuff from config/preloads that one wouldn't
3207      be able to preload at the time the initial heap image is built.
3208      (Many libraries, e.g., CML, do not exist yet at this time.  The
3209       only libraries that can be preloaded via config/preloads are those
3210       that come bundled with the bootfiles.)

3235    Description:
3236    
3237    0. John Reppy made several modifications to the SML/NJ library.
3238       In particular, there is a shiny new controls-lib.cm.
3239    
3240    1. Pushed new controls interface through compiler so that everything
3241       compiles again.
3242    
3243    2. Added FormatComb and FORMAT_COMB to the CML version of the
3244       SML/NJ library (so that CML compiles again).
3245    
3246    3. Modified init scripts because XXX_DEFAULT environment variables
3247       are no longer with us.  (Boot-time initialization is now done
3248       using the same environment variables that are also used for
3249       startup-time initialization of controls.)

3255    Description:
3256    
3257            All pseudo-ops emitted before the first segment declaration
3258    such as TEXT, DATA, and BSS directives are assumed to be global
3259    declarations and are emitted first in the assembly file. This is
3260    useful in a number of situations where one has pseudo-ops that are not
3261    specific to any segment, and also works around the constraint that one
3262    cannot have client pseudo-ops in the TEXT segment.
3263    
3264            Because no segment is associated with these declarations it is
3265    an error to allocate any space or objects before the first segment
3266    directive and an exception will be raised. However, we cannot make
3267    this check for client pseudo-ops.
3268    
3269            These top level declarations are a field in the CFG graph_info.
3270    In theory you can continue to add to this field after the CFG has been
3271    built -- provided you know what you are doing;-)

3279    A few minor bugfixes:

3281      - Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
3282        (Bogus printouts for redefined bindings still occur.  Compiler
3283        bug should no longer occur now.  We need to redo the prettyprinter
3284        from scratch.)

3294    Description:
3295    
3296    Applied the following bugfix provided by Emden Gansner:
3297    
3298        Output is corrupted when outputSubstr is used rather than output.
3299    
3300        The problem occurs when a substring
3301    
3302            ss = (s, dataStart, dataLen)
3303    
3304        where dataStart > 0, fills a stream buffer with avail bytes left.
3305        avail bytes of s, starting at index dataStart, are copied into the
3306        buffer, the buffer is flushed, and then the remaining dataLen-avail
3307        bytes of ss are copied into the beginning of the buffer. Instead of
3308        starting this copy at index dataStart+avail in s, the current code
3309        starts the copy at index avail.
3310    
3311        Fix:
3312        In text-io-fn.sml, change line 695 from
3313             val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3314        to
3315             val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)
