44    Description:
45    
46    Added preliminary support in MLRISC for Staged Allocation, a technique
47    for specifying calling conventions (see
48    http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
49    Initially, we plan to use this code to generate C calls for the AMD64.
50    
51    The staged allocation code base resides in MLRISC/staged-allocation,
52    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

61      promoted to tagless pair.

70        val a1 = Word8Array.array(a1, 0w0);
71        val _  = Word8Array.update(a1, 0, 0w128);
72    
73        x86MCEmitter crashed when the immediate operand to MOVB was outside
74    of the range -128 ... 127.  I've changed the code so that the range
75    check is disabled.   Only the low order 8 bits of the immediate operand
76    are now significant.

84    Eliminated any mention of lexgen.  (Lexgen was an early precursor
85    to ml-ulex.)

87    You should update your admin directory, so the shell scripts for
88    maintaining your local copy of the repository reflect this change.

117    Description:
118    
119    Brought ml-lpt manual up-to-date with the code.  Many minor
120    improvements to the tools, and a few minor bugfixes.  Prepared
121    ml-lpt-lib for integration with new UTF8 structure.  Changed
122    the interface for creating streams in ml-ulex (we now support
123    stream creation from several kinds of sources).  Overall, the
124    tools are now quite stable, and their interfaces are unlikely to
125    change in a way that would break compatibility.  More work,
126    however, is needed in the documentation.

131    Description:
132    
133    Implemented library installer.  Moved CM plugin code for
134    ml-burg, ml-lex, and ml-yacc out of CM source tree and into
135    their respective trees.  Implemented CM plugin for ml-ulex
136    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
137    and ml-antlr.
138    
139    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
140    CM tools.  (It turns out to be too messy to do otherwise because
141    there is too much code that during installation relies on the presence
142    of these tools -- resulting in a tricky ordering problem.)

147    Description:
148    
149    Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
150    Modified CM's startup code to use shiftArgs as it processes
151    command line arguments.  This way, the init code in each .sml-file
152    or library that is mentioned at the top level will see only
153    those arguments that have not yet been processed at this point.
154    In other words, the init code can "seize control" and process the
155    remaining command line.

212    
213    Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to
214    get the c_cc termios data copied correctly.  Also moved the allocation
215    of the string to avoid problems if it caused a GC.
216    
217    Thanks to Timothy Bourke for the bug report and fix.

221    Date: 2006/12/08 09:50:00 CST
222    Description:
223    
224    Added code to CM's "standard shell tool" implementation which
225    causes it to tolerate (with a warning) the situation where the shell
226    command fails (e.g., due to the shell command's non-existence)
227    as long as all target files exist.
228    
229    This makes it possible to, e.g., build ml-yacc from sources even if
230    svn checkout messed up the time stamps on files in such a way that
231    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
232    be needed to re-process yacc.grm, but obviously it might not yet be
233    available at that time.)

240    Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and

248    
249    CM now reports undefined anchors as errors and aborts execution
250    rather than silently pressing on using bogus values.

256    
257    Use Say.vsay for printing the "[autoloading]" message, so
258    #set CM.Control.verbose false (or -Ccm.verbose=false) can be used
259    to suppress them.

273    Description:
274    
275    New working release (110.60).  NEW BOOTFILES!
276    
277    This is the first subversion-hosted release.  There are also changes
278    to the directory layout.  Here is a table:
279    
280    (All pathnames are relative to the SML/NJ "root" directory.)
281    
282      config -> config
283    
284      src/cm -> base/cm
285      src/compiler -> base/compiler
286      src/runtime -> base/runtime
287      src/system -> base/system
288    
289      src/cm/pgraph -> pgraph
290    
291      src/READMES -> base/READMES
292      src/$notefile -> base/NOTES/$notefile
293         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
294                           MACOSXINSTALL WININSTALL
295    
296      src/smlnj-lib -> smlnj-lib
297      src/MLRISC -> MLRISC
298      ckit -> ckit
299      src/cml -> cml
300      src/eXene -> eXene
301      src/heap2asm -> heap2asm
302      src/lexgen -> lexgen
303      src/ml-burg -> ml-burg
304      src/ml-lex -> ml-lex
305      src/ml-yacc -> ml-yacc
306      src/ml-nlffi-lib -> nlffi/lib
307      src/ml-nlffigen -> nlffi/gen
308      src/smlnj-c -> smlnj-c
309      src/tools/TraceDebugProf -> trace-debug-profile
310    
311    In addition, there is also a new
312    
313      ml-lpt
314    
315    directory containing two new program generator tools: ml-ulex and
316    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
317    LL(k) parser generator). These tools are currently "beta-quality"
318    
319    The latest versios of the sources can now be obtained anonymously
320    via subversion.  For this, it is useful to first check out
321    
322       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
323    
324    and put the resulting directory on your shell's PATH.  This provides
325    access to three shell scripts: checkout-all.sh, stat-all.sh,
326    and refresh-all.sh.
327    
328    To create a freshly checked-out copy of the sources, do
329    
330       checkout-all.sh [dir]
331    
332    where dir is the optional SML/NJ root directory (default is ".").
333    
334    This creates the above directory layout.  Each subdirectory of
335    the root is under individual subversion control.  The stat-all.sh
336    and refresh-al.sh scripts apply "svn stat" or "svn update" to
337    each of these subtrees.
338    
339    ----------------------------------------------------------------------
340    Name: Matthias Blume (http://www.tti-c.org/blume/)
341    Date: 2006/11/02 12:20:00 CST
342    Description:
343    
344    Reorganized directory layout.
345    
346    This is a temporary solution, more reorganization is to come.
347    
348    The basic idea is to have a number of toplevel trees, each corresponding
349    to a well-defined part of the overall system.  Each part can be
350    maintained individually, even in separate source repositories,
351    although currently we still serve everything out of the main
352    smlnj-gforge tree.
353    
354    Installer and and scripts have been updated to reflect the new
355    layout.  The installer (base/src/system/smlnj/installer) is now
356    "scriptable" to avoid burning too much knowledge about the
357    layout into SML source code.  The main script used by the installer
358    is in config/actions.
359    
360    The main change is that many of the subdirectories of what used to
361    be known as "src" have moved to the toplevel.  The "src" directory
362    itself has moved down into a subtree called "base".  (We may eventually
363    get rid of the extra level of indirection represented by "src".)
364    
365    The layout is now as follows:
366    
367      toplevel tree name | default repository
368                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
369      -------------------+----------------------------------------------------
370      config             | $gf/config/trunk
371                         |
372      base               | $gf/sml/trunk
373                         |
374      smlnj-lib          | $gf/smlnj-lib/trunk
375      MLRISC             | $gf/MLRISC/trunk
376                         |
377      ml-yacc            | $gf/ml-yacc/trunk
378      ml-lex             | $gf/ml-lex/trunk
379      ml-burg            | $gf/ml-burg/trunk
380      lexgen             | $gf/lexgen/trunk
381      heap2asm           | $gf/heap2asm/trunk
382                         |
383      cml                | $gf/cml/trunk
384      eXene              | $gf/eXene/trunk
385      ckit               | $gf/ckit/trunk
386      nlffi              | $gf/nlffi/trunk
387                         |
388      smlnj-c            | $gf/smlnj-c/trunk
389    
390    In $gf/admin there are a few useful shell scripts for checking out
391    and maintaining the entire collection of trees:
392    
393       admin/checkout-all.sh [dir]
394          -- optionally creates dir and checks out all trees from their
395             default repositories; if dir is missing, checkout into .
396       admin/refresh-all.sh [dir]
397          -- looks at all trees (from the above list) in dir (default: .)
398             and runs "svn update" if the tree exists and is under
399             subversion control;
400             non-existing or non-subversion trees are skipped
401       admin/stat-all.sh [dir]
402          -- like refresh-all.sh, but runs "svn stat" instead

419    New working version (110.59).  NEW BOOTFILES!
420    
421    I am freezing 110.59.  Changes other than the version-number increase:
422    
423      eXene:
424    
425         * committed changes to eXene from Alley Stoughton:
426             "fixed bugs in X authorization and resource handling, as well
427              as in the pile and viewport widgets"
428    
429      Runtime:
430        * fixed linking problem with NetBSD 3.x.
431    
432      Lexgen:
433        * lexgen tool handles non-ascii characters in 7-bit mode the same
434          way that ml-lex does
435    
436        * lexgen propagates exceptions the same way that ml-lex does
437    
438      CML:
439        * Fixed a bug in the SyncVar polling functions (iGetPoll,
440          mTakePoll, and mGetPoll) that could lead to livelock.

582    Description:
583    
584    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
585    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
586    at the time when config/preloads is processed, the library has to
587    be referred to by another name.  In 110.57 this would be
588    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
589    to be valid as well.)

644    Tag: blume-22051115-versiontool
645    Description:
646    
647    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
648    file gets loaded as a tool -- by the equivalent of CM.make during the
649    run of CMB.make.  Thus, CMB's path configuration is meaningless for
650    it.  Instead, it has the status of "user code", so it should use
651    $/basis.cm to refer to the Basis library.  (At least that's true for
652    the purpose of bootstrapping the previous change.  In the future it
653    might make sense to have versiontool.cm refer to
654    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
655    compiler itself uses.)
656    
657    Also patched src/system/testml to have it activate those extra anchor
658    bindings in config/extrapathconfig.

663    Tag: blume-22051115-libraries
664    Description:
665    
666    This change affects the way the following libraries are tied into
667    the system:
668    
669       $/basis.cm
670       $/smlnj-lib.cm
671       $/pp-lib.cm
672       $/controls-lib.cm
673       $/html-lib.cm
674       $/ml-yacc-lib.cm
675    
676    These libraries are now internally (as seen from the source code
677    of the implementation itself) known by the following names:
678    
679       $smlnj/basis/basis.cm
680       $smlnj/smlnj-lib/smlnj-lib.cm
681       $smlnj/smlnj-lib/pp-lib.cm
682       $smlnj/smlnj-lib/controls-lib.cm
683       $smlnj/smlnj-lib/html-lib.cm
684       $smlnj/ml-yacc/ml-yacc-lib.cm
685    
686    This makes it possible to work with code that requires different
687    versions of these libraries, and which refers to these libraries using
688    their "default" names (i.e., the first set of names above).  In other
689    words, one can un-define or re-define those default names without
690    compromising the proper functioning of the compiler itself.
691    
692    A similar procedure had already been performed for several of the
693    MLRISC libraries that are linked into the compiler.  I did some
694    cleanup on this code.
695    
696    A new file in the config directory (named extrapathconfig) is
697    responsible for setting up path anchors that the compiler itself does
698    not need, but that are typically required by user code.

878    Description:
879    
880    Added mechanism for re-creating a heap file for the interactive system
881    after configuration variables have been changed.
882    
883       CM.redump_heap : string -> unit
884    
885    This is much like SMLofNJ.exportML, but starting from the resulting
886    heap does not return to the caller of CM.redump_heap but
887    restarts the interactive system from scratch.  The original call of
888    CM.redump_heap does not return but ends the interactive session.
889    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
890    
891    Internally, redump_heap winds the dynamic execution context back to
892    the point where the original heap image was created and re-executes
893    the heap image generation code in the boot code.

939    an mvar, leaving the door open for races.)

1010    Description:
1011    
1012    Implemented new (but still experimental) heap2exec facility.  This is
1013    tested under Mac OS X and should work under Linux (will test shortly).
1014    It will probably also work on the Sparc (will test some time later).
1015    
1016      - removed old "HACKED_STANDALONE" hack from runtime
1017    
1018    To be able to test this, uncomment the request for "heap2asm" in
1019    config/targets prior to installation.  (Notice that this is different
1020    from "heap2exec" mentioned below.  Not a typo.)
1021    
1022    To perform an actual test, run the command
1023    
1024       $ bin/heap2exec heapfile execfile
1025    
1026    (You can put heap2exec on your shell's path.)
1027    
1028    For example, run
1029    
1030      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1031    
1032    This will create a standalone executable called "mly" which you can
1033    then invoke directly as a command.

1178    Tag: blume-20041124-position
1179    Description:
1180    
1181    The compiler can now be compiled in a mode that makes structure Position
1182    equal to Int64.  The default, however, is unchanged (Position = Int31)
1183    for the time being.
1184    
1185    To enable 64-bit positions, use the following procedure:
1186    
1187    1. Start sml
1188    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1189    3. Type
1190          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1191    4. Run CMB.make() as usual.
1192    
1193    This is barely tested.  The only test so far was a little SML program
1194    counting the number of characters in an 8-gigabyte file by
1195    reading it character-by-character.  That test was successful.
1196    
1197    In support of 64-bit positions, a number of new functions have been
1198    added to the runtime system.

1241    - Stripped down the versiontool: It now only handles the version number.
1242      The date string is generated at bootstrap time (during makeml).
1243    
1244    - In a previous commit, fixed a minor issue with how polyequal is being
1245      translated.  In particular, the code now "looks through" abstractions.
1246      This results in slightly fewer polyEqual warnings and hopefully slightly
1247      more efficient code.  Important examples for where this matters are
1248      the new int64 and word64 types.

1265    All the pieces of Word64 are now there, with the exception of the

1267    but for the time being they don't even make sense because LargeWord is
1268    32-bit wide.)
1269    
1270    Also started to add similar support for Int64, but major pieces of that
1271    are still missing.

1277    Description:
1278    
1279    Structure Word64 is now (almost) complete, word literals and patterns
1280    seem to work.  There are a few odd pieces missing.  In particular,
1281    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1282    at the moment.
1283    
1284    Making Word64 official would mean that LargeWord becomes Word64.  But
1285    this requires extreme care because most word-word conversions have to
1286    go through LargeWord, so making a mistake means loss of efficiency or
1287    worse.  Eventually there will be a solution similar to (but actually
1288    simpler than) what I did with IntInf.

1322        shell script code.  The code has access to the $VERSION variable.
1323      - Made corresponding changes to config/install.sh and config/unpack.
1324      - Default contents of config/srcarchiveurl uses $VERSION and
1325        normally does not have to be edited to reflect a version change.
1326    
1327      (As a result, a version change can be done by just editing
1328       config/version, the rest is now automatic.)

1368    Tag: blume-20041020-standalone-backtrace
1369    Description:
1370    
1371    Added a mechanism for getting back-trace information from standalone
1372    programs.  Here is how it works:
1373    
1374       1. The part of the program from which you want to get backtrace
1375          information (usually the whole program) should be wrapped with
1376          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
1377          main program could be modified from something like
1378    
1379             fun main (pgm, args) = ...
1380    
1381         to
1382    
1383            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1384    
1385       2. To be able to access BackTrace.monitor, you have to add
1386          library $smlnj-tdp/plugins.cm to the .cm file that contains your
1387          main function.
1388    
1389       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1390          CM might have created in the past for your project).
1391    
1392       4. Build the system using this command line:
1393    
1394             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1395                      myprog.cm MyProg.main myprog
1396    
1397          instead of the usual
1398    
1399             ml-build myprog.cm MyProg.main myprog
1400    
1401    I changed a library name:
1402    
1403       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1404    
1405    New libraries:
1406    
1407       $smlnj-tdp/back-trace.cm
1408          -- when loaded causes the back-trace plugin to be installed
1409       $smlnj-tdp/coverage.cm
1410          -- when loaded causes the coverage plugin to be installed

1426    Description:
1427    
1428    * Test coverage tool added!
1429    * Further reorganization of tracing-, debugging-, and profiling support:
1430    
1431        - moved original BTImp -- now called BackTrace -- into a separate
1432          library called $/trace-debug-profile.cm
1433        - eliminated all mentions of BTrace from SMLofNJ.Internals
1434        - only the instrumentation mechanism is now left in the compiler proper
1435        - BackTrace module is a plugin which is NOT plugged in by default
1436        - Coverage module is another such plugin
1437    
1438    To get the benefits of any of these plugin modules, the code in
1439    question must be compiled with tdp instrumentation turned on.  This
1440    can be done by setting SMLofNJ.Internals.TDP.mode to true.
1441    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1442    
1443    Plugins are selected at link time.  (Pre-compiled instrumented code
1444    can be re-loaded with different plugins in effect.)  When an
1445    instrumented module is linked, whatever plugins are at that time
1446    enabled will come into effect for that module.
1447    
1448    To enable the back-trace plugin, load library $/trace-debug-profile.cm
1449    and invoke BackTrace.install() (e.g., from the interactive prompt).
1450    To enable the coverage plugin, load the same library and invoke
1451    Coverage.install().
1452    
1453    Back-traces are generated automatically on uncaught exceptions and
1454    when the code in question explicitly invokes BackTrace.trigger().
1455    
1456    Coverage (and execution frequency-) information must be queried
1457    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

1474    Some rationalization of names:

1477       etc.
1478    
1479    This is is preparation of using the original back-trace
1480    instrumentation for other purposes.  "TDP" stands for
1481    Trace/Debug/Profile.
1482    
1483    The control flag controlling whether instrumentation is on or off is now
1484    registered under a different name, so instead of running sml as
1485    
1486     sml -Cinstrument.btrace-mode=true
1487    
1488    one has to say
1489    
1490     sml -Ctdp.instrument=true

1506    Description:
1507    
1508    Fixed handling of keywords in .cm files: After seeing "is" the lexer
1509    treats subsequent occurrences of "group", "library", "source", "is",
1510    "*", and "-" as ordinary identifiers rather than keywords.
1511    
1512    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
1513    is supposed to accept a tool argument called "source", but this did
1514    not work because of the clash with the keyword.

1557    Description:
1558    
1559    * Moved the "version" magic into its own little library under
1560      src/system/smlnj/internal.  This avoids expensive reconstruction of
1561      a stable src/compiler/core.cm.
1562    
1563    * At the same time, structure CompilerVersion is now known as
1564      structure SMLNJVersion.
1565    
1566    * Arranged for the version tool to NOT kick in when rebuilding the system
1567      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
1568      Also, loading the versiontool does not work when rebuilding the system
1569      because CM is not properly initialized at that time.

1574    Tag: blume-20040929-autoversion
1575    Description:
1576    
1577    Implemented some CM magic to have
1578        file src/compiler/TopLevel/main/version.sml
1579    generated automagically.
1580    The version is taken from two files: config/version and config/release.
1581    The first is expected to contain a two-part version number such as 110.49.
1582    The second should contain a single number, but it may be missing.
1583    
1584    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
1585    time the version tool is loaded (which is the first time you say CMB.make),
1586    then the tool will increment the value stored in config/release every
1587    time CMB.make is invoked.
1588    
1589    The binfile format is now insensitive to anything beyond the first
1590    two components of a version number, so bumping the release does not render
1591    binfiles incompatible.  Auto-bumping can be used to keep track of versions
1592    during development without invalidating existing binfiles.
1593    
1594    In any case, every CMB.make updates the date information in version.sml.
1595    (This is the date that is printed in the banner.)

1608    Tag: blume-20040927-controls
1609    Description:
1610    
1611    Added two pieces of functionality to the Controls interface:
1612    
1613    1.   val save'restore: 'a control -> unit -> unit
1614    
1615       grabs the current value of the control in stage 1 and restores it
1616       in stage 2.
1617    
1618    2.   val set' : 'a control * 'a -> unit -> unit
1619    
1620       stores the given value into the control in stage 2 (i.e., delayed)
1621       but does all error checking in stage 1.
1622       (This is for string controls that need to do parse their argument --
1623        something that might fail.  In some cases, notably in CM, one
1624        already knows the intended argument but wants to delay the actual
1625        assignment until a time when error recovery would be more difficult.)
1626    
1627    Changed the handling of controls in tool arguments to classes "sml" and
1628    "lazysml":
1629       - use Controls.save'restore as a more robust way of restoring the
1630         old value (in particular: without having to re-parse the string)
1631       - use controls to handle the "overload" keyword in the init group
1632         (I believe this change actually fixes a long-standing obscure bug.)

1637    Tag: blume-20040927-lazysml
1638    Description:
1639    
1640    Added a new tool class called "lazysml" to CM's tool chest.  The only
1641    difference to "sml" is that compilation is done with Control.lazysml
1642    set to true.  A source of class "lazysml" is automatically recognized
1643    by a file name suffix of ".lml".
1644    
1645    In addition to the above feature, the original class "sml" now also
1646    supports a tool argument "lazy" which has the same effect.  As a
1647    result, the following three lines are equivalent:
1648    
1649        foo.sml : lazysml
1650        foo.sml : sml (lazy)
1651        foo.sml (lazy)
1652    
1653    The setting goes into effect both during parsing and during
1654    compilation.  The original setting is restored right after parsing and
1655    after compilation, respectively.
1656    
1657    In addition to all the above, there is also a general mechanism to set
1658    ANY of the "controls" that are available at the command line via
1659    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
1660    apply as well. (In fact, "lazy" is implemented as a special case of
1661    the general mechanism.)
1662    
1663    The .cm file syntax uses a new keyword tool argument called "with".
1664    There are several ways of indicating the desired settings:
1665    
1666        foo.sml (with:parser.quotations=true)
1667        foo.sml (with:(name:parser.quotations value:true))
1668        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
1669        foo.sml (with:(name1=value1 name2=value2 ...))
1670        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
1671    
1672        etc.
1673    
1674    Another possible abbreviation is to leave out the =v or value:v part
1675    if the name refers to a boolean control (in which case the value is
1676    taken to be true).  Thus, one could get lazy sml also by saying:
1677    
1678        foo.sml (with:parser.lazy-keyword=true)
1679        foo.sml (with:parser.lazy-keyword)
1680        foo.sml (with:(name:parser.lazy-keyword value:true))
1681        foo.sml (with:(name:parser.lazy-keyword))

2033    Description:
2034    
2035    Changed the interface of structures Timer and Unix to match the most
2036    recent Basis spec.
2037    
2038    In the case of Unix there still seems to be an open/weird issue:
2039    
2040       The {text,bin}{In,Out}streamOf functions are supposed to create
2041       fresh streams whenever they are called -- as opposed to have them
2042       return the same stream every time.  This design is supposed to
2043       prevent space leaks caused by proc values hanging on to streams.
2044    
2045       The reap function, on the other hand, is supposed to close the
2046       streams.  This cannot be done without having a handle on the
2047       stream in proc after all...
2048    
2049    I took the liberty to implement the following stopgap solution:
2050    
2051      The proc value hangs on to the most recently created stream(s).
2052      Reap closes those.  If either or both of the two streams hadn't
2053      been created at all yet, then reap will close the corresponding
2054      file descriptors directly.
2055    
2056    PS: I don't understand the original space leak argument anymore.  If
2057    a proc hangs on to the imperative stream, then I/O operations on those
2058    will advance the state of the cached stream and avoid the space leak.

2072    Description:
2073    
2074    CM now ignores (but still accepts) the "owner" information in group
2075    descriptions.  The owner of a group is its next enclosing
2076    library. Each group must have a unique owner.  (There is a virtual
2077    "toplevel" library that owns groups which are not nested within a real
2078    library.)  Previously, each group had to explicitly declare its owner,
2079    and CM would check that such a declaration is correct.  The new scheme
2080    is to have CM check that for each group there is precisely one owning
2081    library.
2082    
2083    The advantage of the new scheme is that the programmer no longer needs
2084    to maintain the somewhat annoying owner information.  The downside is
2085    that CM cannot enforce the ownership rule across multiple runs of
2086    CM.make.  Fortunately, enclosing the same group in two different
2087    libraries A and B which are not part of the same program does not
2088    cause real problems.

2108    
2109    Arranged for ml-build to clean up after itself a little bit better.
2110    The script generates a temporary SML source file and compiles it using
2111    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
2112    gets rid of those at the end, so they don't accumulate under .cm.
2113    
2114    This required a minor change to install.sh because the name of the
2115    metadata directory (default: .cm) is actually configurable at
2116    installation time.

2131    Description:
2132    
2133    Added previously missing support for many socket-related functions
2134    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
2135    for the voluminous patch!
2136    
2137    (I have not tested this patch under win32 yet.)
2138    
2139    Here is David's e-mail:
2140    
2141    Hi,
2142    
2143    Attached to this email you find a diff against sml/nj 110.45
2144    that will enable socket support under Windows.
2145    
2146    To apply the patch (using unix or cygwin)
2147    1) gunzip runtime.diff.gz
2148    2) "cd" into "src/runtime" in the source tree of a fresh
2149       110.45 installation.
2150    3) patch -p 1 < [your/path/to]runtime.diff
2151    
2152    The code compiles fine but has NOT yet been extensively tested.
2153    I only ran a few tests for basic socket client functionality
2154    (which worked fine).  Especially the functions that use ioctl
2155    are not tested at all and might not work (see below).
2156    
2157    I implemented this since we want to move to a newer version of sml/nj
2158    but need socket support in order to use it.  This is the first time I
2159    even had a look at the sml/nj source,  so please review my changes
2160    before making this part of the distribution!  Here are a few issues
2161    that I think might be better for someone to solve who is more
2162    familiar with the sml/nj source (and socket programming):
2163    
2164    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2165      exception since I could not figure out what the windows equivalent
2166      of these functions is
2167    
2168    - In sockets-osdep.h there are a some #include statements that are
2169      only used in a few files that include sockets-osdep.h
2170    
2171    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2172      does not process its return value since I don't know how to
2173      report an error upwards.
2174    
2175    - It would probably be good to have a call to WSACleanup() when
2176      the library is unloaded (if there is such a possibility).
2177      Otherwise I think Windows will take care of this automatically
2178      when the process finishes.
2179    
2180    - I used ioctlsocket() as a replacement for ioctl() but I have
2181      no idea if that is actually the proper replacement on Windows.
2182    
2183    - All these issues are marked in the code by "FIXME" comments.
2184    
2185    We use sml/nj extensively in our products and are quite happy
2186    with it.  I hope this contribution will help you.
2187    
2188    Keep up the good work!
2189

2223    Description:
2224    
2225    The installer now honors the "src-smlnj" target again, although its meaning
2226    has changed from "all sources required for the compiler" to "all sources
2227    the installer knows about".  In other words, if you enable "src-smlnj"
2228    in the "targets" file, then the installer will pull in sources for
2229    everything.  (Notice that this refers to source code only.  Compiled
2230    code is still only installed for modules that were requested explicitly
2231    or which are required for other modules that were requested explicitly.)

2265    Description:
2266    
2267    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
2268    of SML/NJ.  The problem is that
2269    
2270       lib = dlopen(NULL, ...)
2271       f   = dlsym(lib, "malloc");
2272    
2273    does not work on Windows unless we explicitly export symbols
2274    such as 'malloc' during linking.  We fixed this by explicitly
2275    exporting the required symbols with the magic gcc incantation:
2276    
2277        -Wl,--export-all cygwin.def
2278    
2279    where cygwin.def is a file containing all the symbols that
2280    we wish to export.
2281    
2282    I suspect this is a Windows problem and we'll have to
2283    do the same (somehow with windows compilers) when
2284    we build the native win32 version with the system
2285    calls LoadLibrary/GetProcAddress.

2356    (The mechanism was broken and could not be fixed easily.  Moreover,
2357    there does not seem to be any reason not to move all libraries into
2358    lib during installation.  I originally implemented this directive as a
2359    backward-compatibility feature when I first introduced the new CM.
2360    Now that things have been stable for a long time and going back to the
2361    old CM is not an option, there is no reason to keep it around.)

2411    Description:
2412    
2413    I modified the read-eval-print loop so that the autoloader gets
2414    invoked whenever the prettyprinter tries to look up a symbol that
2415    is not currently defined in the toplevel environment but which
2416    appears in CM's autoload registry.  As a result, we see far fewer of
2417    those ?.Foo.Bar.xxx names in the prettyprinter's output.
2418    
2419    In addition to this I tried to clean up some pieces of the Basis
2420    implementation (e.g., Socket, Word8Array) in order to prevent other
2421    instances of these ?.Foo.Bar.xxx names from being printed.
2422    
2423    The mechanism that picks names for types still needs some work, though.
2424    (Right now it seems that if there is a type A.t which is defined to
2425    be B.u, but B is unavailable at toplevel, then A.t gets printed as
2426    "?.B.u" although the perhaps more sensible solution would be to use
2427    "A.t" in this case.  In other words, the prettyprinter should follow
2428    a chain of DEFtycs not farther than there are corresponding toplevel
2429    names in the current environment.)

2435    Description:
2436    
2437    Another installer tweak:  All the ML code for the installer is now
2438    compiled during CMB.make and put into a little library called
2439    $smlnj/installer.cm.  The installation then simply invokes
2440    
2441       sml -m $smlnj/installer.cm
2442    
2443    and everything happens automagically.
2444    
2445    Win32:  ML code senses value of environment variable SMLNJ_HOME.
2446    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
2447            and BINDIR.
2448    
2449    The new scheme guarantees that the ML code responsible for the installation
2450    is in sync with the APIs of the main system.  Also, the installer is
2451    somewhat faster because the installer script is precompiled.

2462    implementations of non-blocking operations from CML's Socket
2463    structure.

2468    Tag: blume-20030924-sockets
2469    Description:
2470    
2471    1. Fixed SOCKET API and implementation to match Basis spec.
2472       This required changing the internal representation of sockets to one
2473       that remembers (for each socket file descriptor) whether it is currently
2474       blocking or non-blocking.  This state is maintained lazily (i.e., a system
2475       call is made only if the state actually needs to change).
2476    
2477    2. OS-specific details of sockets were moved into separate files, thus
2478       making it possible to unify the bulk of the socket implementations
2479       between Unix and Win32.
2480    
2481    3. CML's socket API changed accordingly.
2482       (Note that we need to remove non-blocking functions from this API
2483       since they are redundant in the case of CML!)
2484    
2485    4. CML's socket implementation now makes use of non-blocking functions
2486       provided by Basis, thus removing all OS-dependent code from this part
2487       of CML.
2488    
2489    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

2602    Description:
2603    
2604    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
2605    Modified config/install.bat to take advantage of it.  Also modified
2606    config/install.sh (and called it config/new-install.sh) to take advantage
2607    of it on Unix systems.  (The SML code is (supposed to be) platform-
2608    independent.)
2609    
2610    The installer can now install everything under Win32
2611    as well as under *nix as long as it compiles.
2612    
2613    Other changes:
2614    
2615      - made CML compile again under Win32
2616      - made eXene compile under Win32 (by providing a fake structure UnixSock
2617        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
2618      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
2619        same as type int;  under Win32 it isn't
2620      - fixed some slice-related problems in the win32-specific parts of CML
2621      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
2622        (under Win32, the volume name is case-insensitive, and the
2623        OS.Path code compares volume names for equality)

2642      1. Changed interface to vectors and arrays in Basis to match
2643         (draft) Basis spec.
2644      2. Added signatures and implementations of slices according to
2645         Basis spec.
2646      3. Edited source code throughout the system to make it compile again
2647         under 1. and 2.  (In some cases code had to be added to have it
2648         match the new signatures.)
2649      4. MLRISC should be backward-compatible: the copies of the originals
2650         of files that needed to change under 3. were retained, the .cm files
2651         check the compiler version number and use old versions when
2652         appropriate.
2653      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
2654         dirstream -> string option (in accordance with Basis spec).
2655      6. When generating code that counts lines, ml-lex used function
2656         CharVector.foldli, taking advantage of its old interface.
2657         This has been replaced with the corresponding code from
2658         CharVectorSlice.  (html-lex must be re-lexed!)
2659      7. BitArray in smlnj-lib/Util has been extended/modified to match the
2660         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
2661      8. Removed temporary additions (fromInternal, toInternal) from the
2662         (now obsolete) IntInf in smlnj-lib/Util.
2663      9. Cleaned up structure Byte.
2664     10. Added localOffset, scan, and fromString to Date (according to spec).
2665         Cleaned/corrected implementation of Date.
2666         (Still need to check for correctness; implement better canonicalizeDate.)
2667     11. Added "scan" to signature IEEE_REAL.
2668     12. Some improvements to IntInf [in particular: efficiency-hack for
2669         mod and rem when second operand is 2 (for parity checks).]
2670     13. Changed representation of type Time.time, using a single IntInf.int
2671         value counting microseconds.  This considerably simplified the
2672         implementation of structure Time.  We now support negative time
2673         values; scan and fromString handle signs.
2674     14. Functor PrimIO now takes two additional arguments (VectorSlice and
2675         ArraySlice).

2681    Description:
2682    
2683    This is a major update which comes with a version number bump
2684    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
2685    and an implementation of IntInf in the Basis.
2686    
2687    There are a fairly large number of related changes and updates throughout
2688    the system:
2689    
2690    Basis:
2691            - Implemented IntInf.
2692            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
2693            - Added some missing Real64 operations, most notably Real.toLargeInt.
2694            - Added FixedInt as a synonym for Int32.
2695    
2696    compiler:
2697            * Added support for a built-in intinf type.
2698              - literals
2699              - pattern matching
2700              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
2701              - overloading on literals and operations
2702    
2703            This required adding a primitive type intinf, some additional
2704            primops, and implementations for several non-trivial intinf
2705            operations in Core.  (The intinf type is completely abstract
2706            to the compiler; all operations get delegated back to the Core.)
2707    
2708            * Intinf equality is handled by polyequal.  However, the compiler
2709            does not print its usual warning in this case (since polyequal
2710            is the right thing to do there).
2711    
2712            * Improved the organization of structure InlineT.
2713    
2714            * A word about conversion primops:
2715            If conversions involving intinf do not cancel out during
2716            CPS contract, then the compiler must insert calls to Core functions.
2717            Since all core access must be resolved already during the FLINT
2718            translate phase, it would be too late a the time of CPS contract
2719            to add new Core calls.  For this reason, conversion primops
2720            for intinf carry two arguments:  1. the numeric argument that
2721            they are supposed to convert, and 2. the Core function that
2722            can help with this conversion if necessary.  If CPS contract
2723            eliminates a primop, then the associated Core function becomes
2724            dead and goes away.  Intinf conversion primops that do not get
2725            eliminated by CPS contract get rewritten into calls of their
2726            core functions by a separate, new phase.
2727    
2728    interactive system:
2729            - Control.Print.intinfDepth controls max length of intinf constants
2730            being printed. (Analogous to Control.Print.stringDepth.)
2731            - Cleanup in printutil and pputil: got rid of unused stuff and
2732            duplicates; replaced some of the code with code that makes better
2733            use of library functionality.
2734    
2735    CM:
2736            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
2737            are no longer silent.
2738    
2739    CKIT:
2740            Fixed mismatched uses of Int32 and LargeInt.  I always decided
2741            in favor of LargeInt -- which is now the same as IntInf.
2742            CKIT-knowledgable people should check whether this is what's
2743            intended and otherwise change things back to using Int32 or
2744            FixedInt.
2745    
2746    Throughout the code:
2747            Started using IntInf.int literals and built-in operations
2748            (e.g., comparison with 0) where this seems appropriate.

2768    Description:
2769    
2770    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
2771    
2772        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
2773    
2774    This patch restores SML/NJ's ability to run under win32.  There are a
2775    number of changes, including fixes for several bugs that had gone
2776    unnoticed until now:
2777    
2778      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
2779        trying to run the win32 version from within cygwin.)
2780    
2781      - There are a number of simple .bat scripts that substitute for their
2782        corresponding Unix shell-scripts.  (See below.)
2783    
2784      - The internals of ml-build have been modified slightly.  The main
2785        difference is that instead of calling ".link-sml" (or link-sml.bat)
2786        using OS.Process.system, the ML process delegates this task back
2787        to the script.  Otherwise problems arise in mixed environments such
2788        as Cygwin where scripts look and work like Unix scripts, but
2789        where OS.Process.system cannot run them.
2790    
2791      - In CM, the srcpath pickler used native pathname syntax -- which
2792        is incorrect in the case of cross-compilation.  The new pickle format
2793        is independent of platform-specific naming conventions.
2794    
2795      - Path configuration files (such as lib/pathconfig) can now choose
2796        between native and standard syntax.  Placing a line of the form
2797    
2798            standard!
2799    
2800        into the file causes all subsequent paths to be interpreted using
2801        CM standard pathname syntax (= Unix conventions); a line
2802    
2803            native!
2804    
2805        switches back to native style.  This was needed so that
2806        path config files can be written portably, see src/system/pathconfig.
2807    
2808      - Runtime system:
2809    
2810          - win32-filesys.c:  get_file_time and set_file_time now
2811            access modification time, not creation time.
2812    
2813          - I/O code made aware of new array representation.
2814    
2815          - Bug fixes in X86.prim.masm.
2816    
2817       - src/system/makeml made aware of win32. (For use under cygwin
2818            and other Unix-environments for windows.)
2819    
2820       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
2821         which caused BinIO.inputAll to fail consistently.
2822    
2823    .bat scripts:
2824    
2825       Windows .bat scripts assume that SMLNJ_HOME is defined.
2826    
2827       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
2828         applications (sml, ml-yacc, ml-lex).
2829       - ml-build.bat: analogous to ml-build.
2830       - config\install.bat:  Analogous to config/install.sh.  This requires
2831         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
2832         (nmake etc. must be on the path, and vcvars32 must have been run.)
2833         Moreover, sources for ml-lex and ml-yacc need to exist under src,
2834         and the bootfile hierarchy must have been unpacked under
2835         sml.boot.x86-win32.
2836         The script is very primitive and does a poor job at error checking.
2837         It only installs the base system, ml-lex, and ml-yacc.  No other
2838         libraries are being installed (i.e., you get only those that
2839         are part of the compiler.)
2840       - link-sml.bat:  analogous to .link-sml, but not currently used
2841    
2842    Unrelated bug fixes:
2843    
2844      - ml-nlffigen now exports structures ST_* corresponding to incomplete
2845        types.
2846      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
2847        otherwise.)

2875      1. Added a flag for controlling whether non-exhaustive bindings will
2876         be treated as errors (default is false).
2877      2. Cleaned up the *entire* source tree so that CMB.make goes through
2878         without a single non-exhaustive match- or bind warning.

2884    Description:
2885    
2886    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
2887    
2888       This mainly affects the quality of error messages.  However, some
2889       of the code is now more straightforward than before. (Treatment of
2890       the above four constructs in translate.sml is much simpler than
2891       the "macro-expansion" that was going on before.  Plus, the mach-
2892       compiler no longer gets invoked just to be able to compile an
2893       if-expression.)
2894    
2895    2. The ErrorMsg.Error exception is now caught and absorbed by the
2896       interactive loop.

2902    Description:
2903    
2904        Ported the runtime system to cygwin, which uses the unix
2905    x86-unix bin files.  Missing/buggy features:
2906    
2907       o getnetbyname, getnetbyaddr: these functions seem to be missing in
2908         the Cygwin library.
2909       o Ctrl-C handling may be flaky.
2910       o Windows system calls and Windows I/O are not supported.
2911    
2912       A new set of binfiles is located at:
2913    
2914         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
2915    
2916       This is only needed for bootstrapping the cygwin version of smlnj.
2917       Other x86 versions can use the existing binfiles.

2947    110.37 and 110.38.)
2948    There was another set of potential problems related to the handling of
2949    MLRISC annotations (but those did not yet cause real problems, apparently).

2976    
2977    In good old tradition, there has been a slight hiccup so that we have
2978    to patch 110.42 after the fact.   The old release tag has been replaced
2979    (see below).
2980    
2981    The change solves a problem with two competing approaches the
2982    configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
2983    each other's way.
2984    
2985    This change only affects the runtime system code and the installer script.

3069    
3070    I back-ported my implementation of IEEEReal.fromString from the
3071    idlbasis-devel branch so that we can test it.
3072    
3073    Another small change is that ppDec tries to give more information
3074    than just "<sig>" in the case of functors.  However, this code is
3075    broken in some mysterious way if the functor's body's signature
3076    has not been declared by ascription but gets inferred from the
3077    implementation.  This needs fixing...

3141    - Added ControlUtil structure to control-lib.cm.
3142    - Use it throughout.
3143    - Used Controls facility to define MLRISC controls (as opposed to
3144      registering MLRISC control ref cells with Controls after the fact)
3145    - Fixed messed-up controls priorities.
3146    
3147    * Removed again all the stuff from config/preloads that one wouldn't
3148      be able to preload at the time the initial heap image is built.
3149      (Many libraries, e.g., CML, do not exist yet at this time.  The
3150       only libraries that can be preloaded via config/preloads are those
3151       that come bundled with the bootfiles.)

3177    
3178    0. John Reppy made several modifications to the SML/NJ library.
3179       In particular, there is a shiny new controls-lib.cm.
3180    
3181    1. Pushed new controls interface through compiler so that everything
3182       compiles again.
3183    
3184    2. Added FormatComb and FORMAT_COMB to the CML version of the
3185       SML/NJ library (so that CML compiles again).
3186    
3187    3. Modified init scripts because XXX_DEFAULT environment variables
3188       are no longer with us.  (Boot-time initialization is now done
3189       using the same environment variables that are also used for
3190       startup-time initialization of controls.)

3196    Description:
3197    
3198            All pseudo-ops emitted before the first segment declaration
3199    such as TEXT, DATA, and BSS directives are assumed to be global
3200    declarations and are emitted first in the assembly file. This is
3201    useful in a number of situations where one has pseudo-ops that are not
3202    specific to any segment, and also works around the constraint that one
3203    cannot have client pseudo-ops in the TEXT segment.
3204    
3205            Because no segment is associated with these declarations it is
3206    an error to allocate any space or objects before the first segment
3207    directive and an exception will be raised. However, we cannot make
3208    this check for client pseudo-ops.
3209    
3210            These top level declarations are a field in the CFG graph_info.
3211    In theory you can continue to add to this field after the CFG has been
3212    built -- provided you know what you are doing;-)

3220    A few minor bugfixes:

3223        (Bogus printouts for redefined bindings still occur.  Compiler
3224        bug should no longer occur now.  We need to redo the prettyprinter
3225        from scratch.)

3235    Description:
3236    
3237    Applied the following bugfix provided by Emden Gansner:
3238    
3239        Output is corrupted when outputSubstr is used rather than output.
3240    
3241        The problem occurs when a substring
3242    
3243            ss = (s, dataStart, dataLen)
3244    
3245        where dataStart > 0, fills a stream buffer with avail bytes left.
3246        avail bytes of s, starting at index dataStart, are copied into the
3247        buffer, the buffer is flushed, and then the remaining dataLen-avail
3248        bytes of ss are copied into the beginning of the buffer. Instead of
3249        starting this copy at index dataStart+avail in s, the current code
3250        starts the copy at index avail.
3251    
3252        Fix:
3253        In text-io-fn.sml, change line 695 from
3254             val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3255        to
3256             val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

3272    Description:
3273    
3274    Added full support for div/mod/rem/quot on the x86, using the machine
3275    instruction's two results (without clumsily recomputing the remainder)
3276    directly where appropriate.
3277    
3278    Some more extensive power-of-two support was added to the x86 instruction
3279    selector (avoiding expensive divs, mods, and muls where they can be
3280    replaced with cheaper shifts and masks).  However, this sort of thing
3281    ought to be done earlier, e.g., within the CPS optimizer so that
3282    all architectures benefit from it.
3283    
3284    The compiler compiles to a fixed point, but changes might be somewhat
3285    fragile nevertheless.  Please, report any strange things that you might
3286    see wrt. div/mod/quot/rem...

3292    Description:
3293    
3294    Fixed my broken div/mod logic.  Unfortunately, this means that the
3295    inline code for div/mod now has one more comparison than before.
3296    Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3297    The problem was with quotient = 0, because that alone does not tell
3298    us which way the rounding went.  One then has to look at whether
3299    remainder and divisor have the same sign...  :(
3300    
3301    Anyway, I replaced the bootfiles with fresh ones...

3308    
3309    NEW BOOTFILES!!!    Version number bumped to 110.39.3.
3310    
3311    Primops have changed. This means that the bin/boot-file formats have
3312    changed as well.
3313    
3314    To make sure that there is no confusion, I made a new version.
3315    
3316    
3317    CHANGES:
3318    
3319    * removed REMT from mltree (remainder should never overflow).
3320    
3321    * added primops to deal with divisions of all flavors to the frontend
3322    
3323    * handled these primops all the way through so they map to their respective
3324      MLRISC support
3325    
3326    * used these primops in the implementation of Int, Int32, Word, Word32
3327    
3328    * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
