20    
21    Substantially changed the signature and implementation of AMD64
22    SVID.  It now looks similar to the ia32 SVID, yet uses staged
23    allocation.

62    
63    Added preliminary support in MLRISC for Staged Allocation, a technique
64    for specifying calling conventions (see
65    http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
66    Initially, we plan to use this code to generate C calls for the AMD64.
67    
68    The staged allocation code base resides in MLRISC/staged-allocation,
69    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

78      promoted to tagless pair.

89    
90        x86MCEmitter crashed when the immediate operand to MOVB was outside
91    of the range -128 ... 127.  I've changed the code so that the range
92    check is disabled.   Only the low order 8 bits of the immediate operand
93    are now significant.

101    Eliminated any mention of lexgen.  (Lexgen was an early precursor
102    to ml-ulex.)
103

134    Description:
135    
136    Brought ml-lpt manual up-to-date with the code.  Many minor
137    improvements to the tools, and a few minor bugfixes.  Prepared
138    ml-lpt-lib for integration with new UTF8 structure.  Changed
139    the interface for creating streams in ml-ulex (we now support
140    stream creation from several kinds of sources).  Overall, the
141    tools are now quite stable, and their interfaces are unlikely to
142    change in a way that would break compatibility.  More work,
143    however, is needed in the documentation.

147    Date: 2007/02/01 10:05:00 CST
148    Description:
149    
150    Implemented library installer.  Moved CM plugin code for
151    ml-burg, ml-lex, and ml-yacc out of CM source tree and into
152    their respective trees.  Implemented CM plugin for ml-ulex
153    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
154    and ml-antlr.
155    
156    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
157    CM tools.  (It turns out to be too messy to do otherwise because
158    there is too much code that during installation relies on the presence
159    of these tools -- resulting in a tricky ordering problem.)

164    Description:
165    
166    Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
167    Modified CM's startup code to use shiftArgs as it processes
168    command line arguments.  This way, the init code in each .sml-file
169    or library that is mentioned at the top level will see only
170    those arguments that have not yet been processed at this point.
171    In other words, the init code can "seize control" and process the
172    remaining command line.

229    
230    Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to
231    get the c_cc termios data copied correctly.  Also moved the allocation

238    Date: 2006/12/08 09:50:00 CST
239    Description:
240    
241    Added code to CM's "standard shell tool" implementation which
242    causes it to tolerate (with a warning) the situation where the shell
243    command fails (e.g., due to the shell command's non-existence)
244    as long as all target files exist.
245    
246    This makes it possible to, e.g., build ml-yacc from sources even if
247    svn checkout messed up the time stamps on files in such a way that
248    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
249    be needed to re-process yacc.grm, but obviously it might not yet be
250    available at that time.)

267    rather than silently pressing on using bogus values.

273    
274    Use Say.vsay for printing the "[autoloading]" message, so

289    Tag: release-110.60
290    Description:
291    
292    New working release (110.60).  NEW BOOTFILES!
293    
294    This is the first subversion-hosted release.  There are also changes
295    to the directory layout.  Here is a table:
296    
297    (All pathnames are relative to the SML/NJ "root" directory.)
298    
299      config -> config
300    
301      src/cm -> base/cm
302      src/compiler -> base/compiler
303      src/runtime -> base/runtime
304      src/system -> base/system
305    
306      src/cm/pgraph -> pgraph
307    
308      src/READMES -> base/READMES
309      src/$notefile -> base/NOTES/$notefile
310         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
311                           MACOSXINSTALL WININSTALL
312    
313      src/smlnj-lib -> smlnj-lib
314      src/MLRISC -> MLRISC
315      ckit -> ckit
316      src/cml -> cml
317      src/eXene -> eXene
318      src/heap2asm -> heap2asm
319      src/lexgen -> lexgen
320      src/ml-burg -> ml-burg
321      src/ml-lex -> ml-lex
322      src/ml-yacc -> ml-yacc
323      src/ml-nlffi-lib -> nlffi/lib
324      src/ml-nlffigen -> nlffi/gen
325      src/smlnj-c -> smlnj-c
326      src/tools/TraceDebugProf -> trace-debug-profile
327    
328    In addition, there is also a new
329    
330      ml-lpt
331    
332    directory containing two new program generator tools: ml-ulex and
333    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
334    LL(k) parser generator). These tools are currently "beta-quality"
335    
336    The latest versios of the sources can now be obtained anonymously
337    via subversion.  For this, it is useful to first check out
338    
339       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
340    
341    and put the resulting directory on your shell's PATH.  This provides
342    access to three shell scripts: checkout-all.sh, stat-all.sh,
343    and refresh-all.sh.
344    
345    To create a freshly checked-out copy of the sources, do
346    
347       checkout-all.sh [dir]
348    
349    where dir is the optional SML/NJ root directory (default is ".").
350    
351    This creates the above directory layout.  Each subdirectory of
352    the root is under individual subversion control.  The stat-all.sh
353    and refresh-al.sh scripts apply "svn stat" or "svn update" to
354    each of these subtrees.
355    
356    ----------------------------------------------------------------------
357    Name: Matthias Blume (http://www.tti-c.org/blume/)
358    Date: 2006/11/02 12:20:00 CST
359    Description:
360    
361    Reorganized directory layout.
362    
363    This is a temporary solution, more reorganization is to come.
364    
365    The basic idea is to have a number of toplevel trees, each corresponding
366    to a well-defined part of the overall system.  Each part can be
367    maintained individually, even in separate source repositories,
368    although currently we still serve everything out of the main
369    smlnj-gforge tree.
370    
371    Installer and and scripts have been updated to reflect the new
372    layout.  The installer (base/src/system/smlnj/installer) is now
373    "scriptable" to avoid burning too much knowledge about the
374    layout into SML source code.  The main script used by the installer
375    is in config/actions.
376    
377    The main change is that many of the subdirectories of what used to
378    be known as "src" have moved to the toplevel.  The "src" directory
379    itself has moved down into a subtree called "base".  (We may eventually
380    get rid of the extra level of indirection represented by "src".)
381    
382    The layout is now as follows:
383    
384      toplevel tree name | default repository
385                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
386      -------------------+----------------------------------------------------
387      config             | $gf/config/trunk
388                         |
389      base               | $gf/sml/trunk
390                         |
391      smlnj-lib          | $gf/smlnj-lib/trunk
392      MLRISC             | $gf/MLRISC/trunk
393                         |
394      ml-yacc            | $gf/ml-yacc/trunk
395      ml-lex             | $gf/ml-lex/trunk
396      ml-burg            | $gf/ml-burg/trunk
397      lexgen             | $gf/lexgen/trunk
398      heap2asm           | $gf/heap2asm/trunk
399                         |
400      cml                | $gf/cml/trunk
401      eXene              | $gf/eXene/trunk
402      ckit               | $gf/ckit/trunk
403      nlffi              | $gf/nlffi/trunk
404                         |
405      smlnj-c            | $gf/smlnj-c/trunk
406    
407    In $gf/admin there are a few useful shell scripts for checking out
408    and maintaining the entire collection of trees:
409    
410       admin/checkout-all.sh [dir]
411          -- optionally creates dir and checks out all trees from their
412             default repositories; if dir is missing, checkout into .
413       admin/refresh-all.sh [dir]
414          -- looks at all trees (from the above list) in dir (default: .)
415             and runs "svn update" if the tree exists and is under
416             subversion control;
417             non-existing or non-subversion trees are skipped
418       admin/stat-all.sh [dir]
419          -- like refresh-all.sh, but runs "svn stat" instead

452    
453        * lexgen propagates exceptions the same way that ml-lex does
454    
455      CML:
456        * Fixed a bug in the SyncVar polling functions (iGetPoll,
457          mTakePoll, and mGetPoll) that could lead to livelock.

463    Description:
464    
465    Implemented ml-makedepend (i.e., CM.sources) in a better (more robust)
466    way.  This should hopefully fix the ml-makedepend problem permanently.

472    Description:
473    
474    Fixed long-standing bug with ml-makedepend where it would output a
475    spurious dependency to a non-existing file.  (This is a simple fix.
476    It might need further looking into.)

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

599    Description:
600    
601    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
602    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
603    at the time when config/preloads is processed, the library has to
604    be referred to by another name.  In 110.57 this would be
605    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
606    to be valid as well.)

661    Tag: blume-22051115-versiontool
662  Description:  Description:
663    
664    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
665    file gets loaded as a tool -- by the equivalent of CM.make during the
666    run of CMB.make.  Thus, CMB's path configuration is meaningless for
667    it.  Instead, it has the status of "user code", so it should use
668    $/basis.cm to refer to the Basis library.  (At least that's true for
669    the purpose of bootstrapping the previous change.  In the future it
670    might make sense to have versiontool.cm refer to
671    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
672    compiler itself uses.)
673    
674    Also patched src/system/testml to have it activate those extra anchor
675    bindings in config/extrapathconfig.

680    Tag: blume-22051115-libraries
681    Description:
682    
683    This change affects the way the following libraries are tied into
684    the system:
685    
686       $/basis.cm
687       $/smlnj-lib.cm
688       $/pp-lib.cm
689       $/controls-lib.cm
690       $/html-lib.cm
691       $/ml-yacc-lib.cm
692    
693    These libraries are now internally (as seen from the source code
694    of the implementation itself) known by the following names:
695    
696       $smlnj/basis/basis.cm
697       $smlnj/smlnj-lib/smlnj-lib.cm
698       $smlnj/smlnj-lib/pp-lib.cm
699       $smlnj/smlnj-lib/controls-lib.cm
700       $smlnj/smlnj-lib/html-lib.cm
701       $smlnj/ml-yacc/ml-yacc-lib.cm
702    
703    This makes it possible to work with code that requires different
704    versions of these libraries, and which refers to these libraries using
705    their "default" names (i.e., the first set of names above).  In other
706    words, one can un-define or re-define those default names without
707    compromising the proper functioning of the compiler itself.
708    
709    A similar procedure had already been performed for several of the
710    MLRISC libraries that are linked into the compiler.  I did some
711    cleanup on this code.
712    
713    A new file in the config directory (named extrapathconfig) is
714    responsible for setting up path anchors that the compiler itself does
715    not need, but that are typically required by user code.

895    Description:
896    
897    Added mechanism for re-creating a heap file for the interactive system
898    after configuration variables have been changed.
899    
900       CM.redump_heap : string -> unit
901    
902    This is much like SMLofNJ.exportML, but starting from the resulting
903    heap does not return to the caller of CM.redump_heap but
904    restarts the interactive system from scratch.  The original call of
905    CM.redump_heap does not return but ends the interactive session.
906    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
907    
908    Internally, redump_heap winds the dynamic execution context back to
909    the point where the original heap image was created and re-executes
910    the heap image generation code in the boot code.

927    
928    Added a gc protocol checking phase.  This phase is enabled with
929    the flag "check-gc".  "debug-check-gc" turns on the verbose mode.

1026    Tag: blume-20050114-heap2exec
1027    Description:
1028    
1029    Implemented new (but still experimental) heap2exec facility.  This is
1030    tested under Mac OS X and should work under Linux (will test shortly).
1031    It will probably also work on the Sparc (will test some time later).
1032    
1033      - removed old "HACKED_STANDALONE" hack from runtime
1034    
1035    To be able to test this, uncomment the request for "heap2asm" in
1036    config/targets prior to installation.  (Notice that this is different
1037    from "heap2exec" mentioned below.  Not a typo.)
1038    
1039    To perform an actual test, run the command
1040    
1041       $ bin/heap2exec heapfile execfile
1042    
1043    (You can put heap2exec on your shell's path.)
1044    
1045    For example, run
1046    
1047      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1048    
1049    This will create a standalone executable called "mly" which you can
1050    then invoke directly as a command.

1195    Tag: blume-20041124-position
1196    Description:
1197    
1198    The compiler can now be compiled in a mode that makes structure Position
1199    equal to Int64.  The default, however, is unchanged (Position = Int31)
1200    for the time being.
1201    
1202    To enable 64-bit positions, use the following procedure:
1203    
1204    1. Start sml
1205    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1206    3. Type
1207          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1208    4. Run CMB.make() as usual.
1209    
1210    This is barely tested.  The only test so far was a little SML program
1211    counting the number of characters in an 8-gigabyte file by
1212    reading it character-by-character.  That test was successful.
1213    
1214    In support of 64-bit positions, a number of new functions have been
1215    added to the runtime system.

1258    - Stripped down the versiontool: It now only handles the version number.
1259      The date string is generated at bootstrap time (during makeml).
1260    
1261    - In a previous commit, fixed a minor issue with how polyequal is being
1262      translated.  In particular, the code now "looks through" abstractions.
1263      This results in slightly fewer polyEqual warnings and hopefully slightly
1264      more efficient code.  Important examples for where this matters are
1265      the new int64 and word64 types.

1282    All the pieces of Word64 are now there, with the exception of the
1283    conversions from and to LargeWord. (Eventually these need to be identities,
1284    but for the time being they don't even make sense because LargeWord is
1285    32-bit wide.)
1286    
1287    Also started to add similar support for Int64, but major pieces of that
1288    are still missing.

1294    Description:
1295    
1296    Structure Word64 is now (almost) complete, word literals and patterns
1297    seem to work.  There are a few odd pieces missing.  In particular,
1298    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1299    at the moment.
1300    
1301    Making Word64 official would mean that LargeWord becomes Word64.  But
1302    this requires extreme care because most word-word conversions have to
1303    go through LargeWord, so making a mistake means loss of efficiency or
1304    worse.  Eventually there will be a solution similar to (but actually
1305    simpler than) what I did with IntInf.

1338        containing the URL string into a file containing
1339        shell script code.  The code has access to the $VERSION variable.
1340      - Made corresponding changes to config/install.sh and config/unpack.
1341      - Default contents of config/srcarchiveurl uses $VERSION and
1342        normally does not have to be edited to reflect a version change.
1343    
1344      (As a result, a version change can be done by just editing
1345       config/version, the rest is now automatic.)

1362    This is the HISTORY entry for two earlier commits, both concerning
1363    the x86 c-calls code in MLRISC:
1364    
1365      - added a missing LOAD in the code that deals with struct arguments
1366      - made sure the caller does not add the wrong number of bytes to the
1367        stack pointer after a call of a function returning a struct
1368        (the callee already pops the implicit argument which points to
1369         the space reserved for the result)

1385    Tag: blume-20041020-standalone-backtrace
1386    Description:
1387    
1388    Added a mechanism for getting back-trace information from standalone
1389    programs.  Here is how it works:
1390    
1391       1. The part of the program from which you want to get backtrace
1392          information (usually the whole program) should be wrapped with
1393          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
1394          main program could be modified from something like
1395    
1396             fun main (pgm, args) = ...
1397    
1398         to
1399    
1400            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1401    
1402       2. To be able to access BackTrace.monitor, you have to add
1403          library $smlnj-tdp/plugins.cm to the .cm file that contains your
1404          main function.
1405    
1406       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1407          CM might have created in the past for your project).
1408    
1409       4. Build the system using this command line:
1410    
1411             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1412                      myprog.cm MyProg.main myprog
1413    
1414          instead of the usual
1415    
1416             ml-build myprog.cm MyProg.main myprog
1417    
1418    I changed a library name:
1419    
1420       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1421    
1422    New libraries:
1423    
1424       $smlnj-tdp/back-trace.cm
1425          -- when loaded causes the back-trace plugin to be installed
1426       $smlnj-tdp/coverage.cm
1427          -- when loaded causes the coverage plugin to be installed

1443    Description:
1444    
1445    * Test coverage tool added!
1446    * Further reorganization of tracing-, debugging-, and profiling support:
1447    
1448        - moved original BTImp -- now called BackTrace -- into a separate
1449          library called $/trace-debug-profile.cm
1450        - eliminated all mentions of BTrace from SMLofNJ.Internals
1451        - only the instrumentation mechanism is now left in the compiler proper
1452        - BackTrace module is a plugin which is NOT plugged in by default
1453        - Coverage module is another such plugin
1454    
1455    To get the benefits of any of these plugin modules, the code in
1456    question must be compiled with tdp instrumentation turned on.  This
1457    can be done by setting SMLofNJ.Internals.TDP.mode to true.
1458    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1459    
1460    Plugins are selected at link time.  (Pre-compiled instrumented code
1461    can be re-loaded with different plugins in effect.)  When an
1462    instrumented module is linked, whatever plugins are at that time
1463    enabled will come into effect for that module.
1464    
1465    To enable the back-trace plugin, load library $/trace-debug-profile.cm
1466    and invoke BackTrace.install() (e.g., from the interactive prompt).
1467    To enable the coverage plugin, load the same library and invoke
1468    Coverage.install().
1469    
1470    Back-traces are generated automatically on uncaught exceptions and
1471    when the code in question explicitly invokes BackTrace.trigger().
1472    
1473    Coverage (and execution frequency-) information must be queried
1474    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

1490    
1491    Some rationalization of names:

1493       structure BTrace -> structure TDPInstrument
1494       etc.
1495    
1496    This is is preparation of using the original back-trace
1497    instrumentation for other purposes.  "TDP" stands for
1498    Trace/Debug/Profile.
1499    
1500    The control flag controlling whether instrumentation is on or off is now
1501    registered under a different name, so instead of running sml as
1502    
1503     sml -Cinstrument.btrace-mode=true
1504    
1505    one has to say
1506    
1507     sml -Ctdp.instrument=true

1522    Tag: blume-20041008-cmkw
1523    Description:
1524    
1525    Fixed handling of keywords in .cm files: After seeing "is" the lexer
1526    treats subsequent occurrences of "group", "library", "source", "is",
1527    "*", and "-" as ordinary identifiers rather than keywords.
1528    
1529    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
1530    is supposed to accept a tool argument called "source", but this did
1531    not work because of the clash with the keyword.

1574    Description:
1575    
1576    * Moved the "version" magic into its own little library under
1577      src/system/smlnj/internal.  This avoids expensive reconstruction of
1578      a stable src/compiler/core.cm.
1579    
1580    * At the same time, structure CompilerVersion is now known as
1581      structure SMLNJVersion.
1582    
1583    * Arranged for the version tool to NOT kick in when rebuilding the system
1584      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
1585      Also, loading the versiontool does not work when rebuilding the system
1586      because CM is not properly initialized at that time.

1591    Tag: blume-20040929-autoversion
1592    Description:
1593    
1594    Implemented some CM magic to have
1595        file src/compiler/TopLevel/main/version.sml
1596    generated automagically.
1597    The version is taken from two files: config/version and config/release.
1598    The first is expected to contain a two-part version number such as 110.49.
1599    The second should contain a single number, but it may be missing.
1600    
1601    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
1602    time the version tool is loaded (which is the first time you say CMB.make),
1603    then the tool will increment the value stored in config/release every
1604    time CMB.make is invoked.
1605    
1606    The binfile format is now insensitive to anything beyond the first
1607    two components of a version number, so bumping the release does not render
1608    binfiles incompatible.  Auto-bumping can be used to keep track of versions
1609    during development without invalidating existing binfiles.
1610    
1611    In any case, every CMB.make updates the date information in version.sml.
1612    (This is the date that is printed in the banner.)

1625    Tag: blume-20040927-controls
1626    Description:
1627    
1628    Added two pieces of functionality to the Controls interface:
1629    
1630    1.   val save'restore: 'a control -> unit -> unit
1631    
1632       grabs the current value of the control in stage 1 and restores it
1633       in stage 2.
1634    
1635    2.   val set' : 'a control * 'a -> unit -> unit
1636    
1637       stores the given value into the control in stage 2 (i.e., delayed)
1638       but does all error checking in stage 1.
1639       (This is for string controls that need to do parse their argument --
1640        something that might fail.  In some cases, notably in CM, one
1641        already knows the intended argument but wants to delay the actual
1642        assignment until a time when error recovery would be more difficult.)
1643    
1644    Changed the handling of controls in tool arguments to classes "sml" and
1645    "lazysml":
1646       - use Controls.save'restore as a more robust way of restoring the
1647         old value (in particular: without having to re-parse the string)
1648       - use controls to handle the "overload" keyword in the init group
1649         (I believe this change actually fixes a long-standing obscure bug.)

1654    Tag: blume-20040927-lazysml
1655    Description:
1656    
1657    Added a new tool class called "lazysml" to CM's tool chest.  The only
1658    difference to "sml" is that compilation is done with Control.lazysml
1659    set to true.  A source of class "lazysml" is automatically recognized
1660    by a file name suffix of ".lml".
1661    
1662    In addition to the above feature, the original class "sml" now also
1663    supports a tool argument "lazy" which has the same effect.  As a
1664    result, the following three lines are equivalent:
1665    
1666        foo.sml : lazysml
1667        foo.sml : sml (lazy)
1668        foo.sml (lazy)
1669    
1670    The setting goes into effect both during parsing and during
1671    compilation.  The original setting is restored right after parsing and
1672    after compilation, respectively.
1673    
1674    In addition to all the above, there is also a general mechanism to set
1675    ANY of the "controls" that are available at the command line via
1676    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
1677    apply as well. (In fact, "lazy" is implemented as a special case of
1678    the general mechanism.)
1679    
1680    The .cm file syntax uses a new keyword tool argument called "with".
1681    There are several ways of indicating the desired settings:
1682    
1683        foo.sml (with:parser.quotations=true)
1684        foo.sml (with:(name:parser.quotations value:true))
1685        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
1686        foo.sml (with:(name1=value1 name2=value2 ...))
1687        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
1688    
1689        etc.
1690    
1691    Another possible abbreviation is to leave out the =v or value:v part
1692    if the name refers to a boolean control (in which case the value is
1693    taken to be true).  Thus, one could get lazy sml also by saying:
1694    
1695        foo.sml (with:parser.lazy-keyword=true)
1696        foo.sml (with:parser.lazy-keyword)
1697        foo.sml (with:(name:parser.lazy-keyword value:true))
1698        foo.sml (with:(name:parser.lazy-keyword))

1794    - improved ML code of installer to fall back to coping when renaming
1795      fails (i.e., when source and target are on different file systems);
1796      the code compiles but has yet to be tested in anger
1797    - removed mlrisc from list of default targets (config/targets)

2050    Description:
2051    
2052    Changed the interface of structures Timer and Unix to match the most
2053    recent Basis spec.
2054    
2055    In the case of Unix there still seems to be an open/weird issue:
2056    
2057       The {text,bin}{In,Out}streamOf functions are supposed to create
2058       fresh streams whenever they are called -- as opposed to have them
2059       return the same stream every time.  This design is supposed to
2060       prevent space leaks caused by proc values hanging on to streams.
2061    
2062       The reap function, on the other hand, is supposed to close the
2063       streams.  This cannot be done without having a handle on the
2064       stream in proc after all...
2065    
2066    I took the liberty to implement the following stopgap solution:
2067    
2068      The proc value hangs on to the most recently created stream(s).
2069      Reap closes those.  If either or both of the two streams hadn't
2070      been created at all yet, then reap will close the corresponding
2071      file descriptors directly.
2072    
2073    PS: I don't understand the original space leak argument anymore.  If
2074    a proc hangs on to the imperative stream, then I/O operations on those
2075    will advance the state of the cached stream and avoid the space leak.

2089    Description:
2090    
2091    CM now ignores (but still accepts) the "owner" information in group
2092    descriptions.  The owner of a group is its next enclosing
2093    library. Each group must have a unique owner.  (There is a virtual
2094    "toplevel" library that owns groups which are not nested within a real
2095    library.)  Previously, each group had to explicitly declare its owner,
2096    and CM would check that such a declaration is correct.  The new scheme
2097    is to have CM check that for each group there is precisely one owning
2098    library.
2099    
2100    The advantage of the new scheme is that the programmer no longer needs
2101    to maintain the somewhat annoying owner information.  The downside is
2102    that CM cannot enforce the ownership rule across multiple runs of
2103    CM.make.  Fortunately, enclosing the same group in two different
2104    libraries A and B which are not part of the same program does not
2105    cause real problems.

2126    Arranged for ml-build to clean up after itself a little bit better.
2127    The script generates a temporary SML source file and compiles it using
2128    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
2129    gets rid of those at the end, so they don't accumulate under .cm.
2130    
2131    This required a minor change to install.sh because the name of the
2132    metadata directory (default: .cm) is actually configurable at
2133    installation time.

2148    Description:
2149    
2150    Added previously missing support for many socket-related functions
2151    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
2152    for the voluminous patch!
2153    
2154    (I have not tested this patch under win32 yet.)
2155    
2156    Here is David's e-mail:
2157    
2158    Hi,
2159    
2160    Attached to this email you find a diff against sml/nj 110.45
2161    that will enable socket support under Windows.
2162    
2163    To apply the patch (using unix or cygwin)
2164    1) gunzip runtime.diff.gz
2165    2) "cd" into "src/runtime" in the source tree of a fresh
2166       110.45 installation.
2167    3) patch -p 1 < [your/path/to]runtime.diff
2168    
2169    The code compiles fine but has NOT yet been extensively tested.
2170    I only ran a few tests for basic socket client functionality
2171    (which worked fine).  Especially the functions that use ioctl
2172    are not tested at all and might not work (see below).
2173    
2174    I implemented this since we want to move to a newer version of sml/nj
2175    but need socket support in order to use it.  This is the first time I
2176    even had a look at the sml/nj source,  so please review my changes
2177    before making this part of the distribution!  Here are a few issues
2178    that I think might be better for someone to solve who is more
2179    familiar with the sml/nj source (and socket programming):
2180    
2181    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2182      exception since I could not figure out what the windows equivalent
2183      of these functions is
2184    
2185    - In sockets-osdep.h there are a some #include statements that are
2186      only used in a few files that include sockets-osdep.h
2187    
2188    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2189      does not process its return value since I don't know how to
2190      report an error upwards.
2191    
2192    - It would probably be good to have a call to WSACleanup() when
2193      the library is unloaded (if there is such a possibility).
2194      Otherwise I think Windows will take care of this automatically
2195      when the process finishes.
2196    
2197    - I used ioctlsocket() as a replacement for ioctl() but I have
2198      no idea if that is actually the proper replacement on Windows.
2199    
2200    - All these issues are marked in the code by "FIXME" comments.
2201    
2202    We use sml/nj extensively in our products and are quite happy
2203    with it.  I hope this contribution will help you.
2204    
2205    Keep up the good work!
2206

2240    Description:
2241    
2242    The installer now honors the "src-smlnj" target again, although its meaning
2243    has changed from "all sources required for the compiler" to "all sources
2244    the installer knows about".  In other words, if you enable "src-smlnj"
2245    in the "targets" file, then the installer will pull in sources for
2246    everything.  (Notice that this refers to source code only.  Compiled
2247    code is still only installed for modules that were requested explicitly
2248    or which are required for other modules that were requested explicitly.)

2282    Description:
2283    
2284    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
2285    of SML/NJ.  The problem is that
2286    
2287       lib = dlopen(NULL, ...)
2288       f   = dlsym(lib, "malloc");
2289    
2290    does not work on Windows unless we explicitly export symbols
2291    such as 'malloc' during linking.  We fixed this by explicitly
2292    exporting the required symbols with the magic gcc incantation:
2293    
2294        -Wl,--export-all cygwin.def
2295    
2296    where cygwin.def is a file containing all the symbols that
2297    we wish to export.
2298    
2299    I suspect this is a Windows problem and we'll have to
2300    do the same (somehow with windows compilers) when
2301    we build the native win32 version with the system
2302    calls LoadLibrary/GetProcAddress.

2373    (The mechanism was broken and could not be fixed easily.  Moreover,
2374    there does not seem to be any reason not to move all libraries into
2375    lib during installation.  I originally implemented this directive as a
2376    backward-compatibility feature when I first introduced the new CM.
2377    Now that things have been stable for a long time and going back to the
2378    old CM is not an option, there is no reason to keep it around.)

2428    Description:
2429    
2430    I modified the read-eval-print loop so that the autoloader gets
2431    invoked whenever the prettyprinter tries to look up a symbol that
2432    is not currently defined in the toplevel environment but which
2433    appears in CM's autoload registry.  As a result, we see far fewer of
2434    those ?.Foo.Bar.xxx names in the prettyprinter's output.
2435    
2436    In addition to this I tried to clean up some pieces of the Basis
2437    implementation (e.g., Socket, Word8Array) in order to prevent other
2438    instances of these ?.Foo.Bar.xxx names from being printed.
2439    
2440    The mechanism that picks names for types still needs some work, though.
2441    (Right now it seems that if there is a type A.t which is defined to
2442    be B.u, but B is unavailable at toplevel, then A.t gets printed as
2443    "?.B.u" although the perhaps more sensible solution would be to use
2444    "A.t" in this case.  In other words, the prettyprinter should follow
2445    a chain of DEFtycs not farther than there are corresponding toplevel
2446    names in the current environment.)

2452    Description:
2453    
2454    Another installer tweak:  All the ML code for the installer is now
2455    compiled during CMB.make and put into a little library called
2456    $smlnj/installer.cm.  The installation then simply invokes
2457    
2458       sml -m $smlnj/installer.cm
2459    
2460    and everything happens automagically.
2461    
2462    Win32:  ML code senses value of environment variable SMLNJ_HOME.
2463    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
2464            and BINDIR.
2465    
2466    The new scheme guarantees that the ML code responsible for the installation
2467    is in sync with the APIs of the main system.  Also, the installer is
2468    somewhat faster because the installer script is precompiled.

2479    implementations of non-blocking operations from CML's Socket
2480    structure.

2485    Tag: blume-20030924-sockets
2486    Description:
2487    
2488    1. Fixed SOCKET API and implementation to match Basis spec.
2489       This required changing the internal representation of sockets to one
2490       that remembers (for each socket file descriptor) whether it is currently
2491       blocking or non-blocking.  This state is maintained lazily (i.e., a system
2492       call is made only if the state actually needs to change).
2493    
2494    2. OS-specific details of sockets were moved into separate files, thus
2495       making it possible to unify the bulk of the socket implementations
2496       between Unix and Win32.
2497    
2498    3. CML's socket API changed accordingly.
2499       (Note that we need to remove non-blocking functions from this API
2500       since they are redundant in the case of CML!)
2501    
2502    4. CML's socket implementation now makes use of non-blocking functions
2503       provided by Basis, thus removing all OS-dependent code from this part
2504       of CML.
2505    
2506    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

2619    Description:
2620    
2621    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
2622    Modified config/install.bat to take advantage of it.  Also modified
2623    config/install.sh (and called it config/new-install.sh) to take advantage
2624    of it on Unix systems.  (The SML code is (supposed to be) platform-
2625    independent.)
2626    
2627    The installer can now install everything under Win32
2628    as well as under *nix as long as it compiles.
2629    
2630    Other changes:
2631    
2632      - made CML compile again under Win32
2633      - made eXene compile under Win32 (by providing a fake structure UnixSock
2634        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
2635      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
2636        same as type int;  under Win32 it isn't
2637      - fixed some slice-related problems in the win32-specific parts of CML
2638      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
2639        (under Win32, the volume name is case-insensitive, and the
2640        OS.Path code compares volume names for equality)

2647    
2648    Made Win32 version of OS.FileSys.fullPath return current directory
2649    when given an empty string.  This is what the spec says, and incidentally,
2650    CM depends on it.  (CM otherwise goes into an infinite loop in certain
2651    cases when presented with the name of a non-existing .cm file.)

2657    Description:
2658    
2659      1. Changed interface to vectors and arrays in Basis to match
2660         (draft) Basis spec.
2661      2. Added signatures and implementations of slices according to
2662         Basis spec.
2663      3. Edited source code throughout the system to make it compile again
2664         under 1. and 2.  (In some cases code had to be added to have it
2665         match the new signatures.)
2666      4. MLRISC should be backward-compatible: the copies of the originals
2667         of files that needed to change under 3. were retained, the .cm files
2668         check the compiler version number and use old versions when
2669         appropriate.
2670      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
2671         dirstream -> string option (in accordance with Basis spec).
2672      6. When generating code that counts lines, ml-lex used function
2673         CharVector.foldli, taking advantage of its old interface.
2674         This has been replaced with the corresponding code from
2675         CharVectorSlice.  (html-lex must be re-lexed!)
2676      7. BitArray in smlnj-lib/Util has been extended/modified to match the
2677         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
2678      8. Removed temporary additions (fromInternal, toInternal) from the
2679         (now obsolete) IntInf in smlnj-lib/Util.
2680      9. Cleaned up structure Byte.
2681     10. Added localOffset, scan, and fromString to Date (according to spec).
2682         Cleaned/corrected implementation of Date.
2683         (Still need to check for correctness; implement better canonicalizeDate.)
2684     11. Added "scan" to signature IEEE_REAL.
2685     12. Some improvements to IntInf [in particular: efficiency-hack for
2686         mod and rem when second operand is 2 (for parity checks).]
2687     13. Changed representation of type Time.time, using a single IntInf.int
2688         value counting microseconds.  This considerably simplified the
2689         implementation of structure Time.  We now support negative time
2690         values; scan and fromString handle signs.
2691     14. Functor PrimIO now takes two additional arguments (VectorSlice and
2692         ArraySlice).

2698    Description:
2699    
2700    This is a major update which comes with a version number bump
2701    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
2702    and an implementation of IntInf in the Basis.
2703    
2704    There are a fairly large number of related changes and updates throughout
2705    the system:
2706    
2707    Basis:
2708            - Implemented IntInf.
2709            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
2710            - Added some missing Real64 operations, most notably Real.toLargeInt.
2711            - Added FixedInt as a synonym for Int32.
2712    
2713    compiler:
2714            * Added support for a built-in intinf type.
2715              - literals
2716              - pattern matching
2717              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
2718              - overloading on literals and operations
2719    
2720            This required adding a primitive type intinf, some additional
2721            primops, and implementations for several non-trivial intinf
2722            operations in Core.  (The intinf type is completely abstract
2723            to the compiler; all operations get delegated back to the Core.)
2724    
2725            * Intinf equality is handled by polyequal.  However, the compiler
2726            does not print its usual warning in this case (since polyequal
2727            is the right thing to do there).
2728    
2729            * Improved the organization of structure InlineT.
2730    
2731            * A word about conversion primops:
2732            If conversions involving intinf do not cancel out during
2733            CPS contract, then the compiler must insert calls to Core functions.
2734            Since all core access must be resolved already during the FLINT
2735            translate phase, it would be too late a the time of CPS contract
2736            to add new Core calls.  For this reason, conversion primops
2737            for intinf carry two arguments:  1. the numeric argument that
2738            they are supposed to convert, and 2. the Core function that
2739            can help with this conversion if necessary.  If CPS contract
2740            eliminates a primop, then the associated Core function becomes
2741            dead and goes away.  Intinf conversion primops that do not get
2742            eliminated by CPS contract get rewritten into calls of their
2743            core functions by a separate, new phase.
2744    
2745    interactive system:
2746            - Control.Print.intinfDepth controls max length of intinf constants
2747            being printed. (Analogous to Control.Print.stringDepth.)
2748            - Cleanup in printutil and pputil: got rid of unused stuff and
2749            duplicates; replaced some of the code with code that makes better
2750            use of library functionality.
2751    
2752    CM:
2753            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
2754            are no longer silent.
2755    
2756    CKIT:
2757            Fixed mismatched uses of Int32 and LargeInt.  I always decided
2758            in favor of LargeInt -- which is now the same as IntInf.
2759            CKIT-knowledgable people should check whether this is what's
2760            intended and otherwise change things back to using Int32 or
2761            FixedInt.
2762    
2763    Throughout the code:
2764            Started using IntInf.int literals and built-in operations
2765            (e.g., comparison with 0) where this seems appropriate.

2785    Description:
2786    
2787    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
2788    
2789        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
2790    
2791    This patch restores SML/NJ's ability to run under win32.  There are a
2792    number of changes, including fixes for several bugs that had gone
2793    unnoticed until now:
2794    
2795      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
2796        trying to run the win32 version from within cygwin.)
2797    
2798      - There are a number of simple .bat scripts that substitute for their
2799        corresponding Unix shell-scripts.  (See below.)
2800    
2801      - The internals of ml-build have been modified slightly.  The main
2802        difference is that instead of calling ".link-sml" (or link-sml.bat)
2803        using OS.Process.system, the ML process delegates this task back
2804        to the script.  Otherwise problems arise in mixed environments such
2805        as Cygwin where scripts look and work like Unix scripts, but
2806        where OS.Process.system cannot run them.
2807    
2808      - In CM, the srcpath pickler used native pathname syntax -- which
2809        is incorrect in the case of cross-compilation.  The new pickle format
2810        is independent of platform-specific naming conventions.
2811    
2812      - Path configuration files (such as lib/pathconfig) can now choose
2813        between native and standard syntax.  Placing a line of the form
2814    
2815            standard!
2816    
2817        into the file causes all subsequent paths to be interpreted using
2818        CM standard pathname syntax (= Unix conventions); a line
2819    
2820            native!
2821    
2822        switches back to native style.  This was needed so that
2823        path config files can be written portably, see src/system/pathconfig.
2824    
2825      - Runtime system:
2826    
2827          - win32-filesys.c:  get_file_time and set_file_time now
2828            access modification time, not creation time.
2829    
2830          - I/O code made aware of new array representation.
2831    
2832          - Bug fixes in X86.prim.masm.
2833    
2834       - src/system/makeml made aware of win32. (For use under cygwin
2835            and other Unix-environments for windows.)
2836    
2837       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
2838         which caused BinIO.inputAll to fail consistently.
2839    
2840    .bat scripts:
2841    
2842       Windows .bat scripts assume that SMLNJ_HOME is defined.
2843    
2844       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
2845         applications (sml, ml-yacc, ml-lex).
2846       - ml-build.bat: analogous to ml-build.
2847       - config\install.bat:  Analogous to config/install.sh.  This requires
2848         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
2849         (nmake etc. must be on the path, and vcvars32 must have been run.)
2850         Moreover, sources for ml-lex and ml-yacc need to exist under src,
2851         and the bootfile hierarchy must have been unpacked under
2852         sml.boot.x86-win32.
2853         The script is very primitive and does a poor job at error checking.
2854         It only installs the base system, ml-lex, and ml-yacc.  No other
2855         libraries are being installed (i.e., you get only those that
2856         are part of the compiler.)
2857       - link-sml.bat:  analogous to .link-sml, but not currently used
2858    
2859    Unrelated bug fixes:
2860    
2861      - ml-nlffigen now exports structures ST_* corresponding to incomplete
2862        types.
2863      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
2864        otherwise.)

2892      1. Added a flag for controlling whether non-exhaustive bindings will
2893         be treated as errors (default is false).
2894      2. Cleaned up the *entire* source tree so that CMB.make goes through
2895         without a single non-exhaustive match- or bind warning.

2901    Description:
2902    
2903    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
2904    
2905       This mainly affects the quality of error messages.  However, some
2906       of the code is now more straightforward than before. (Treatment of
2907       the above four constructs in translate.sml is much simpler than
2908       the "macro-expansion" that was going on before.  Plus, the mach-
2909       compiler no longer gets invoked just to be able to compile an
2910       if-expression.)
2911    
2912    2. The ErrorMsg.Error exception is now caught and absorbed by the
2913       interactive loop.

2919    Description:
2920    
2921        Ported the runtime system to cygwin, which uses the unix
2922    x86-unix bin files.  Missing/buggy features:
2923    
2924       o getnetbyname, getnetbyaddr: these functions seem to be missing in
2925         the Cygwin library.
2926       o Ctrl-C handling may be flaky.
2927       o Windows system calls and Windows I/O are not supported.
2928    
2929       A new set of binfiles is located at:
2930    
2931         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
2932    
2933       This is only needed for bootstrapping the cygwin version of smlnj.
2934       Other x86 versions can use the existing binfiles.
