34    Description:
35    
36    Added preliminary support in MLRISC for Staged Allocation, a technique
37    for specifying calling conventions (see
38    http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
39    Initially, we plan to use this code to generate C calls for the AMD64.
40    
41    The staged allocation code base resides in MLRISC/staged-allocation,
42    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

58        Bug triggered by:

60        val a1 = Word8Array.array(a1, 0w0);
61        val _  = Word8Array.update(a1, 0, 0w128);
62    
63        x86MCEmitter crashed when the immediate operand to MOVB was outside
64    of the range -128 ... 127.  I've changed the code so that the range
65    check is disabled.   Only the low order 8 bits of the immediate operand
66    are now significant.

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

107    Description:
108    
109    Brought ml-lpt manual up-to-date with the code.  Many minor
110    improvements to the tools, and a few minor bugfixes.  Prepared
111    ml-lpt-lib for integration with new UTF8 structure.  Changed
112    the interface for creating streams in ml-ulex (we now support
113    stream creation from several kinds of sources).  Overall, the
114    tools are now quite stable, and their interfaces are unlikely to
115    change in a way that would break compatibility.  More work,
116    however, is needed in the documentation.

120    Date: 2007/02/01 10:05:00 CST
121    Description:
122    
123    Implemented library installer.  Moved CM plugin code for
124    ml-burg, ml-lex, and ml-yacc out of CM source tree and into
125    their respective trees.  Implemented CM plugin for ml-ulex
126    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
127    and ml-antlr.
128    
129    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
130    CM tools.  (It turns out to be too messy to do otherwise because
131    there is too much code that during installation relies on the presence
132    of these tools -- resulting in a tricky ordering problem.)

137    Description:
138    
139    Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
140    Modified CM's startup code to use shiftArgs as it processes
141    command line arguments.  This way, the init code in each .sml-file
142    or library that is mentioned at the top level will see only
143    those arguments that have not yet been processed at this point.
144    In other words, the init code can "seize control" and process the
145    remaining command line.

202    
203    Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to
204    get the c_cc termios data copied correctly.  Also moved the allocation
205    of the string to avoid problems if it caused a GC.
206    
207    Thanks to Timothy Bourke for the bug report and fix.

210    Name: Matthias Blume (http://www.tti-c.org/blume)
211    Date: 2006/12/08 09:50:00 CST
212    Description:
213    
214    Added code to CM's "standard shell tool" implementation which
215    causes it to tolerate (with a warning) the situation where the shell
216    command fails (e.g., due to the shell command's non-existence)
217    as long as all target files exist.
218    
219    This makes it possible to, e.g., build ml-yacc from sources even if
220    svn checkout messed up the time stamps on files in such a way that
221    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
222    be needed to re-process yacc.grm, but obviously it might not yet be
223    available at that time.)

229    
230    Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
231    recvVecFromNB' in the SOCKET signature.  This error is actually
232    in the SML Basis specification too.

238    
239    CM now reports undefined anchors as errors and aborts execution
240    rather than silently pressing on using bogus values.

246    
247    Use Say.vsay for printing the "[autoloading]" message, so
248    #set CM.Control.verbose false (or -Ccm.verbose=false) can be used
249    to suppress them.

263    Description:
264    
265    New working release (110.60).  NEW BOOTFILES!
266    
267    This is the first subversion-hosted release.  There are also changes
268    to the directory layout.  Here is a table:
269    
270    (All pathnames are relative to the SML/NJ "root" directory.)
271    
272      config -> config
273    
274      src/cm -> base/cm
275      src/compiler -> base/compiler
276      src/runtime -> base/runtime
277      src/system -> base/system
278    
279      src/cm/pgraph -> pgraph
280    
281      src/READMES -> base/READMES
282      src/$notefile -> base/NOTES/$notefile
283         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
284                           MACOSXINSTALL WININSTALL
285    
286      src/smlnj-lib -> smlnj-lib
287      src/MLRISC -> MLRISC
288      ckit -> ckit
289      src/cml -> cml
290      src/eXene -> eXene
291      src/heap2asm -> heap2asm
292      src/lexgen -> lexgen
293      src/ml-burg -> ml-burg
294      src/ml-lex -> ml-lex
295      src/ml-yacc -> ml-yacc
296      src/ml-nlffi-lib -> nlffi/lib
297      src/ml-nlffigen -> nlffi/gen
298      src/smlnj-c -> smlnj-c
299      src/tools/TraceDebugProf -> trace-debug-profile
300    
301    In addition, there is also a new
302    
303      ml-lpt
304    
305    directory containing two new program generator tools: ml-ulex and
306    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
307    LL(k) parser generator). These tools are currently "beta-quality"
308    
309    The latest versios of the sources can now be obtained anonymously
310    via subversion.  For this, it is useful to first check out
311    
312       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
313    
314    and put the resulting directory on your shell's PATH.  This provides
315    access to three shell scripts: checkout-all.sh, stat-all.sh,
316    and refresh-all.sh.
317    
318    To create a freshly checked-out copy of the sources, do
319    
320       checkout-all.sh [dir]
321    
322    where dir is the optional SML/NJ root directory (default is ".").
323    
324    This creates the above directory layout.  Each subdirectory of
325    the root is under individual subversion control.  The stat-all.sh
326    and refresh-al.sh scripts apply "svn stat" or "svn update" to
327    each of these subtrees.
328    
329    ----------------------------------------------------------------------
330    Name: Matthias Blume (http://www.tti-c.org/blume/)
331    Date: 2006/11/02 12:20:00 CST
332    Description:
333    
334    Reorganized directory layout.
335    
336    This is a temporary solution, more reorganization is to come.
337    
338    The basic idea is to have a number of toplevel trees, each corresponding
339    to a well-defined part of the overall system.  Each part can be
340    maintained individually, even in separate source repositories,
341    although currently we still serve everything out of the main
342    smlnj-gforge tree.
343    
344    Installer and and scripts have been updated to reflect the new
345    layout.  The installer (base/src/system/smlnj/installer) is now
346    "scriptable" to avoid burning too much knowledge about the
347    layout into SML source code.  The main script used by the installer
348    is in config/actions.
349    
350    The main change is that many of the subdirectories of what used to
351    be known as "src" have moved to the toplevel.  The "src" directory
352    itself has moved down into a subtree called "base".  (We may eventually
353    get rid of the extra level of indirection represented by "src".)
354    
355    The layout is now as follows:
356    
357      toplevel tree name | default repository
358                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
359      -------------------+----------------------------------------------------
360      config             | $gf/config/trunk
361                         |
362      base               | $gf/sml/trunk
363                         |
364      smlnj-lib          | $gf/smlnj-lib/trunk
365      MLRISC             | $gf/MLRISC/trunk
366                         |
367      ml-yacc            | $gf/ml-yacc/trunk
368      ml-lex             | $gf/ml-lex/trunk
369      ml-burg            | $gf/ml-burg/trunk
370      lexgen             | $gf/lexgen/trunk
371      heap2asm           | $gf/heap2asm/trunk
372                         |
373      cml                | $gf/cml/trunk
374      eXene              | $gf/eXene/trunk
375      ckit               | $gf/ckit/trunk
376      nlffi              | $gf/nlffi/trunk
377                         |
378      smlnj-c            | $gf/smlnj-c/trunk
379    
380    In $gf/admin there are a few useful shell scripts for checking out
381    and maintaining the entire collection of trees:
382    
383       admin/checkout-all.sh [dir]
384          -- optionally creates dir and checks out all trees from their
385             default repositories; if dir is missing, checkout into .
386       admin/refresh-all.sh [dir]
387          -- looks at all trees (from the above list) in dir (default: .)
388             and runs "svn update" if the tree exists and is under
389             subversion control;
390             non-existing or non-subversion trees are skipped
391       admin/stat-all.sh [dir]
392          -- like refresh-all.sh, but runs "svn stat" instead

411    I am freezing 110.59.  Changes other than the version-number increase:
412    
413      eXene:
414    
415         * committed changes to eXene from Alley Stoughton:
416             "fixed bugs in X authorization and resource handling, as well
417              as in the pile and viewport widgets"
418    
419      Runtime:
420        * fixed linking problem with NetBSD 3.x.
421    
422      Lexgen:
423        * lexgen tool handles non-ascii characters in 7-bit mode the same
424          way that ml-lex does
425    
426        * lexgen propagates exceptions the same way that ml-lex does
427    
428      CML:
429        * Fixed a bug in the SyncVar polling functions (iGetPoll,
430          mTakePoll, and mGetPoll) that could lead to livelock.

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

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

572    Description:
573    
574    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
575    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
576    at the time when config/preloads is processed, the library has to
577    be referred to by another name.  In 110.57 this would be
578    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
579    to be valid as well.)

634    Tag: blume-22051115-versiontool
635    Description:
636    
637    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
638    file gets loaded as a tool -- by the equivalent of CM.make during the
639    run of CMB.make.  Thus, CMB's path configuration is meaningless for
640    it.  Instead, it has the status of "user code", so it should use
641    $/basis.cm to refer to the Basis library.  (At least that's true for
642    the purpose of bootstrapping the previous change.  In the future it
643    might make sense to have versiontool.cm refer to
644    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
645    compiler itself uses.)
646    
647    Also patched src/system/testml to have it activate those extra anchor
648    bindings in config/extrapathconfig.

653    Tag: blume-22051115-libraries
654    Description:
655    
656    This change affects the way the following libraries are tied into
657    the system:
658    
659       $/basis.cm
660       $/smlnj-lib.cm
661       $/pp-lib.cm
662       $/controls-lib.cm
663       $/html-lib.cm
664       $/ml-yacc-lib.cm
665    
666    These libraries are now internally (as seen from the source code
667    of the implementation itself) known by the following names:
668    
669       $smlnj/basis/basis.cm
670       $smlnj/smlnj-lib/smlnj-lib.cm
671       $smlnj/smlnj-lib/pp-lib.cm
672       $smlnj/smlnj-lib/controls-lib.cm
673       $smlnj/smlnj-lib/html-lib.cm
674       $smlnj/ml-yacc/ml-yacc-lib.cm
675    
676    This makes it possible to work with code that requires different
677    versions of these libraries, and which refers to these libraries using
678    their "default" names (i.e., the first set of names above).  In other
679    words, one can un-define or re-define those default names without
680    compromising the proper functioning of the compiler itself.
681    
682    A similar procedure had already been performed for several of the
683    MLRISC libraries that are linked into the compiler.  I did some
684    cleanup on this code.
685    
686    A new file in the config directory (named extrapathconfig) is
687    responsible for setting up path anchors that the compiler itself does
688    not need, but that are typically required by user code.

868    Description:
869    
870    Added mechanism for re-creating a heap file for the interactive system
871    after configuration variables have been changed.
872    
873       CM.redump_heap : string -> unit
874    
875    This is much like SMLofNJ.exportML, but starting from the resulting
876    heap does not return to the caller of CM.redump_heap but
877    restarts the interactive system from scratch.  The original call of
878    CM.redump_heap does not return but ends the interactive session.
879    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
880    
881    Internally, redump_heap winds the dynamic execution context back to
882    the point where the original heap image was created and re-executes
883    the heap image generation code in the boot code.

999    Tag: blume-20050114-heap2exec
1000    Description:
1001    
1002    Implemented new (but still experimental) heap2exec facility.  This is
1003    tested under Mac OS X and should work under Linux (will test shortly).
1004    It will probably also work on the Sparc (will test some time later).
1005    
1006      - removed old "HACKED_STANDALONE" hack from runtime
1007    
1008    To be able to test this, uncomment the request for "heap2asm" in
1009    config/targets prior to installation.  (Notice that this is different
1010    from "heap2exec" mentioned below.  Not a typo.)
1011    
1012    To perform an actual test, run the command
1013    
1014       $ bin/heap2exec heapfile execfile
1015    
1016    (You can put heap2exec on your shell's path.)
1017    
1018    For example, run
1019    
1020      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1021    
1022    This will create a standalone executable called "mly" which you can
1023    then invoke directly as a command.

1168    Tag: blume-20041124-position
1169    Description:
1170    
1171    The compiler can now be compiled in a mode that makes structure Position
1172    equal to Int64.  The default, however, is unchanged (Position = Int31)
1173    for the time being.
1174    
1175    To enable 64-bit positions, use the following procedure:
1176    
1177    1. Start sml
1178    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1179    3. Type
1180          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1181    4. Run CMB.make() as usual.
1182    
1183    This is barely tested.  The only test so far was a little SML program
1184    counting the number of characters in an 8-gigabyte file by
1185    reading it character-by-character.  That test was successful.
1186    
1187    In support of 64-bit positions, a number of new functions have been
1188    added to the runtime system.

1231    - Stripped down the versiontool: It now only handles the version number.
1232      The date string is generated at bootstrap time (during makeml).
1233    
1234    - In a previous commit, fixed a minor issue with how polyequal is being
1235      translated.  In particular, the code now "looks through" abstractions.
1236      This results in slightly fewer polyEqual warnings and hopefully slightly
1237      more efficient code.  Important examples for where this matters are
1238      the new int64 and word64 types.

1255    All the pieces of Word64 are now there, with the exception of the
1256    conversions from and to LargeWord. (Eventually these need to be identities,
1257    but for the time being they don't even make sense because LargeWord is
1258    32-bit wide.)
1259    
1260    Also started to add similar support for Int64, but major pieces of that
1261    are still missing.

1267    Description:
1268    
1269    Structure Word64 is now (almost) complete, word literals and patterns
1270    seem to work.  There are a few odd pieces missing.  In particular,
1271    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1272    at the moment.
1273    
1274    Making Word64 official would mean that LargeWord becomes Word64.  But
1275    this requires extreme care because most word-word conversions have to
1276    go through LargeWord, so making a mistake means loss of efficiency or
1277    worse.  Eventually there will be a solution similar to (but actually
1278    simpler than) what I did with IntInf.

1311        containing the URL string into a file containing
1312        shell script code.  The code has access to the $VERSION variable.
1313      - Made corresponding changes to config/install.sh and config/unpack.
1314      - Default contents of config/srcarchiveurl uses $VERSION and
1315        normally does not have to be edited to reflect a version change.
1316    
1317      (As a result, a version change can be done by just editing
1318       config/version, the rest is now automatic.)

1359    Description:
1360    
1361    Added a mechanism for getting back-trace information from standalone
1362    programs.  Here is how it works:
1363    
1364       1. The part of the program from which you want to get backtrace
1365          information (usually the whole program) should be wrapped with
1366          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
1367          main program could be modified from something like
1368    
1369             fun main (pgm, args) = ...
1370    
1371         to
1372    
1373            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1374    
1375       2. To be able to access BackTrace.monitor, you have to add
1376          library $smlnj-tdp/plugins.cm to the .cm file that contains your
1377          main function.
1378    
1379       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1380          CM might have created in the past for your project).
1381    
1382       4. Build the system using this command line:
1383    
1384             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1385                      myprog.cm MyProg.main myprog
1386    
1387          instead of the usual
1388    
1389             ml-build myprog.cm MyProg.main myprog
1390    
1391    I changed a library name:
1392    
1393       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1394    
1395    New libraries:
1396    
1397       $smlnj-tdp/back-trace.cm
1398          -- when loaded causes the back-trace plugin to be installed
1399       $smlnj-tdp/coverage.cm
1400          -- when loaded causes the coverage plugin to be installed
1401

1416    Description:
1417    
1418    * Test coverage tool added!
1419    * Further reorganization of tracing-, debugging-, and profiling support:
1420    
1421        - moved original BTImp -- now called BackTrace -- into a separate
1422          library called $/trace-debug-profile.cm
1423        - eliminated all mentions of BTrace from SMLofNJ.Internals
1424        - only the instrumentation mechanism is now left in the compiler proper
1425        - BackTrace module is a plugin which is NOT plugged in by default
1426        - Coverage module is another such plugin
1427    
1428    To get the benefits of any of these plugin modules, the code in
1429    question must be compiled with tdp instrumentation turned on.  This
1430    can be done by setting SMLofNJ.Internals.TDP.mode to true.
1431    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1432    
1433    Plugins are selected at link time.  (Pre-compiled instrumented code
1434    can be re-loaded with different plugins in effect.)  When an
1435    instrumented module is linked, whatever plugins are at that time
1436    enabled will come into effect for that module.
1437    
1438    To enable the back-trace plugin, load library $/trace-debug-profile.cm
1439    and invoke BackTrace.install() (e.g., from the interactive prompt).
1440    To enable the coverage plugin, load the same library and invoke
1441    Coverage.install().
1442    
1443    Back-traces are generated automatically on uncaught exceptions and
1444    when the code in question explicitly invokes BackTrace.trigger().
1445    
1446    Coverage (and execution frequency-) information must be queried
1447    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

1462    Description:
1463    
1464    Some rationalization of names:
1465    
1466       structure BTrace -> structure TDPInstrument
1467       etc.
1468    
1469    This is is preparation of using the original back-trace
1470    instrumentation for other purposes.  "TDP" stands for
1471    Trace/Debug/Profile.
1472    
1473    The control flag controlling whether instrumentation is on or off is now
1474    registered under a different name, so instead of running sml as
1475    
1476     sml -Cinstrument.btrace-mode=true
1477    
1478    one has to say
1479    
1480     sml -Ctdp.instrument=true

1495    Tag: blume-20041008-cmkw
1496    Description:
1497    
1498    Fixed handling of keywords in .cm files: After seeing "is" the lexer
1499    treats subsequent occurrences of "group", "library", "source", "is",
1500    "*", and "-" as ordinary identifiers rather than keywords.
1501    
1502    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
1503    is supposed to accept a tool argument called "source", but this did
1504    not work because of the clash with the keyword.

1517      - simplified tokentable implementation

1541    attached.  I don't know if this is worth fixing...)

1547    Description:
1548    
1549    * Moved the "version" magic into its own little library under
1550      src/system/smlnj/internal.  This avoids expensive reconstruction of
1551      a stable src/compiler/core.cm.
1552    
1553    * At the same time, structure CompilerVersion is now known as
1554      structure SMLNJVersion.
1555    
1556    * Arranged for the version tool to NOT kick in when rebuilding the system
1557      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
1558      Also, loading the versiontool does not work when rebuilding the system
1559      because CM is not properly initialized at that time.

1564    Tag: blume-20040929-autoversion
1565    Description:
1566    
1567    Implemented some CM magic to have
1568        file src/compiler/TopLevel/main/version.sml
1569    generated automagically.
1570    The version is taken from two files: config/version and config/release.
1571    The first is expected to contain a two-part version number such as 110.49.
1572    The second should contain a single number, but it may be missing.
1573    
1574    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
1575    time the version tool is loaded (which is the first time you say CMB.make),
1576    then the tool will increment the value stored in config/release every
1577    time CMB.make is invoked.
1578    
1579    The binfile format is now insensitive to anything beyond the first
1580    two components of a version number, so bumping the release does not render
1581    binfiles incompatible.  Auto-bumping can be used to keep track of versions
1582    during development without invalidating existing binfiles.
1583    
1584    In any case, every CMB.make updates the date information in version.sml.
1585    (This is the date that is printed in the banner.)

1598    Tag: blume-20040927-controls
1599    Description:
1600    
1601    Added two pieces of functionality to the Controls interface:
1602    
1603    1.   val save'restore: 'a control -> unit -> unit
1604    
1605       grabs the current value of the control in stage 1 and restores it
1606       in stage 2.
1607    
1608    2.   val set' : 'a control * 'a -> unit -> unit
1609    
1610       stores the given value into the control in stage 2 (i.e., delayed)
1611       but does all error checking in stage 1.
1612       (This is for string controls that need to do parse their argument --
1613        something that might fail.  In some cases, notably in CM, one
1614        already knows the intended argument but wants to delay the actual
1615        assignment until a time when error recovery would be more difficult.)
1616    
1617    Changed the handling of controls in tool arguments to classes "sml" and
1618    "lazysml":
1619       - use Controls.save'restore as a more robust way of restoring the
1620         old value (in particular: without having to re-parse the string)
1621       - use controls to handle the "overload" keyword in the init group
1622         (I believe this change actually fixes a long-standing obscure bug.)

1627    Tag: blume-20040927-lazysml
1628    Description:
1629    
1630    Added a new tool class called "lazysml" to CM's tool chest.  The only
1631    difference to "sml" is that compilation is done with Control.lazysml
1632    set to true.  A source of class "lazysml" is automatically recognized
1633    by a file name suffix of ".lml".
1634    
1635    In addition to the above feature, the original class "sml" now also
1636    supports a tool argument "lazy" which has the same effect.  As a
1637    result, the following three lines are equivalent:
1638    
1639        foo.sml : lazysml
1640        foo.sml : sml (lazy)
1641        foo.sml (lazy)
1642    
1643    The setting goes into effect both during parsing and during
1644    compilation.  The original setting is restored right after parsing and
1645    after compilation, respectively.
1646    
1647    In addition to all the above, there is also a general mechanism to set
1648    ANY of the "controls" that are available at the command line via
1649    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
1650    apply as well. (In fact, "lazy" is implemented as a special case of
1651    the general mechanism.)
1652    
1653    The .cm file syntax uses a new keyword tool argument called "with".
1654    There are several ways of indicating the desired settings:
1655    
1656        foo.sml (with:parser.quotations=true)
1657        foo.sml (with:(name:parser.quotations value:true))
1658        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
1659        foo.sml (with:(name1=value1 name2=value2 ...))
1660        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
1661    
1662        etc.
1663    
1664    Another possible abbreviation is to leave out the =v or value:v part
1665    if the name refers to a boolean control (in which case the value is
1666    taken to be true).  Thus, one could get lazy sml also by saying:
1667    
1668        foo.sml (with:parser.lazy-keyword=true)
1669        foo.sml (with:parser.lazy-keyword)
1670        foo.sml (with:(name:parser.lazy-keyword value:true))
1671        foo.sml (with:(name:parser.lazy-keyword))

1819    
1820    Bug fix from Carl Hauser:
1821    
1822    single_source_shortest_paths in dijkstra.sml was observed to get wrong
1823    answers (by comparing to single_source_shortest_paths in bellman-ford.sml).
1824    
1825    The problem is that following the expression A.update(dist,s,Num.zero)
1826    it is necessary to update the priority queue using Q.decreaseWeight(Q,s).

2023    Description:
2024    
2025    Changed the interface of structures Timer and Unix to match the most
2026    recent Basis spec.
2027    
2028    In the case of Unix there still seems to be an open/weird issue:
2029    
2030       The {text,bin}{In,Out}streamOf functions are supposed to create
2031       fresh streams whenever they are called -- as opposed to have them
2032       return the same stream every time.  This design is supposed to
2033       prevent space leaks caused by proc values hanging on to streams.
2034    
2035       The reap function, on the other hand, is supposed to close the
2036       streams.  This cannot be done without having a handle on the
2037       stream in proc after all...
2038    
2039    I took the liberty to implement the following stopgap solution:
2040    
2041      The proc value hangs on to the most recently created stream(s).
2042      Reap closes those.  If either or both of the two streams hadn't
2043      been created at all yet, then reap will close the corresponding
2044      file descriptors directly.
2045    
2046    PS: I don't understand the original space leak argument anymore.  If
2047    a proc hangs on to the imperative stream, then I/O operations on those
2048    will advance the state of the cached stream and avoid the space leak.

2062    Description:
2063    
2064    CM now ignores (but still accepts) the "owner" information in group
2065    descriptions.  The owner of a group is its next enclosing
2066    library. Each group must have a unique owner.  (There is a virtual
2067    "toplevel" library that owns groups which are not nested within a real
2068    library.)  Previously, each group had to explicitly declare its owner,
2069    and CM would check that such a declaration is correct.  The new scheme
2070    is to have CM check that for each group there is precisely one owning
2071    library.
2072    
2073    The advantage of the new scheme is that the programmer no longer needs
2074    to maintain the somewhat annoying owner information.  The downside is
2075    that CM cannot enforce the ownership rule across multiple runs of
2076    CM.make.  Fortunately, enclosing the same group in two different
2077    libraries A and B which are not part of the same program does not
2078    cause real problems.

2097    Description:
2098    
2099    Arranged for ml-build to clean up after itself a little bit better.
2100    The script generates a temporary SML source file and compiles it using
2101    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
2102    gets rid of those at the end, so they don't accumulate under .cm.
2103    
2104    This required a minor change to install.sh because the name of the
2105    metadata directory (default: .cm) is actually configurable at
2106    installation time.

2122    
2123    Added previously missing support for many socket-related functions
2124    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
2125    for the voluminous patch!
2126    
2127    (I have not tested this patch under win32 yet.)
2128    
2129    Here is David's e-mail:
2130    
2131    Hi,
2132    
2133    Attached to this email you find a diff against sml/nj 110.45
2134    that will enable socket support under Windows.
2135    
2136    To apply the patch (using unix or cygwin)
2137    1) gunzip runtime.diff.gz
2138    2) "cd" into "src/runtime" in the source tree of a fresh
2139       110.45 installation.
2140    3) patch -p 1 < [your/path/to]runtime.diff
2141    
2142    The code compiles fine but has NOT yet been extensively tested.
2143    I only ran a few tests for basic socket client functionality
2144    (which worked fine).  Especially the functions that use ioctl
2145    are not tested at all and might not work (see below).
2146    
2147    I implemented this since we want to move to a newer version of sml/nj
2148    but need socket support in order to use it.  This is the first time I
2149    even had a look at the sml/nj source,  so please review my changes
2150    before making this part of the distribution!  Here are a few issues
2151    that I think might be better for someone to solve who is more
2152    familiar with the sml/nj source (and socket programming):
2153    
2154    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2155      exception since I could not figure out what the windows equivalent
2156      of these functions is
2157    
2158    - In sockets-osdep.h there are a some #include statements that are
2159      only used in a few files that include sockets-osdep.h
2160    
2161    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2162      does not process its return value since I don't know how to
2163      report an error upwards.
2164    
2165    - It would probably be good to have a call to WSACleanup() when
2166      the library is unloaded (if there is such a possibility).
2167      Otherwise I think Windows will take care of this automatically
2168      when the process finishes.
2169    
2170    - I used ioctlsocket() as a replacement for ioctl() but I have
2171      no idea if that is actually the proper replacement on Windows.
2172    
2173    - All these issues are marked in the code by "FIXME" comments.
2174    
2175    We use sml/nj extensively in our products and are quite happy
2176    with it.  I hope this contribution will help you.
2177    
2178    Keep up the good work!
2179

2215    The installer now honors the "src-smlnj" target again, although its meaning
2216    has changed from "all sources required for the compiler" to "all sources
2217    the installer knows about".  In other words, if you enable "src-smlnj"
2218    in the "targets" file, then the installer will pull in sources for
2219    everything.  (Notice that this refers to source code only.  Compiled
2220    code is still only installed for modules that were requested explicitly
2221    or which are required for other modules that were requested explicitly.)

2255    Description:
2256    
2257    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
2258    of SML/NJ.  The problem is that
2259    
2260       lib = dlopen(NULL, ...)
2261       f   = dlsym(lib, "malloc");
2262    
2263    does not work on Windows unless we explicitly export symbols
2264    such as 'malloc' during linking.  We fixed this by explicitly
2265    exporting the required symbols with the magic gcc incantation:
2266    
2267        -Wl,--export-all cygwin.def
2268    
2269    where cygwin.def is a file containing all the symbols that
2270    we wish to export.
2271    
2272    I suspect this is a Windows problem and we'll have to
2273    do the same (somehow with windows compilers) when
2274    we build the native win32 version with the system
2275    calls LoadLibrary/GetProcAddress.

2346    (The mechanism was broken and could not be fixed easily.  Moreover,
2347    there does not seem to be any reason not to move all libraries into
2348    lib during installation.  I originally implemented this directive as a
2349    backward-compatibility feature when I first introduced the new CM.
2350    Now that things have been stable for a long time and going back to the
2351    old CM is not an option, there is no reason to keep it around.)

2401    Description:
2402    
2403    I modified the read-eval-print loop so that the autoloader gets
2404    invoked whenever the prettyprinter tries to look up a symbol that
2405    is not currently defined in the toplevel environment but which
2406    appears in CM's autoload registry.  As a result, we see far fewer of
2407    those ?.Foo.Bar.xxx names in the prettyprinter's output.
2408    
2409    In addition to this I tried to clean up some pieces of the Basis
2410    implementation (e.g., Socket, Word8Array) in order to prevent other
2411    instances of these ?.Foo.Bar.xxx names from being printed.
2412    
2413    The mechanism that picks names for types still needs some work, though.
2414    (Right now it seems that if there is a type A.t which is defined to
2415    be B.u, but B is unavailable at toplevel, then A.t gets printed as
2416    "?.B.u" although the perhaps more sensible solution would be to use
2417    "A.t" in this case.  In other words, the prettyprinter should follow
2418    a chain of DEFtycs not farther than there are corresponding toplevel
2419    names in the current environment.)

2425    Description:
2426    
2427    Another installer tweak:  All the ML code for the installer is now
2428    compiled during CMB.make and put into a little library called
2429    $smlnj/installer.cm.  The installation then simply invokes
2430    
2431       sml -m $smlnj/installer.cm
2432    
2433    and everything happens automagically.
2434    
2435    Win32:  ML code senses value of environment variable SMLNJ_HOME.
2436    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
2437            and BINDIR.
2438    
2439    The new scheme guarantees that the ML code responsible for the installation
2440    is in sync with the APIs of the main system.  Also, the installer is
2441    somewhat faster because the installer script is precompiled.

2452    implementations of non-blocking operations from CML's Socket
2453    structure.

2458    Tag: blume-20030924-sockets
2459    Description:
2460    
2461    1. Fixed SOCKET API and implementation to match Basis spec.
2462       This required changing the internal representation of sockets to one
2463       that remembers (for each socket file descriptor) whether it is currently
2464       blocking or non-blocking.  This state is maintained lazily (i.e., a system
2465       call is made only if the state actually needs to change).
2466    
2467    2. OS-specific details of sockets were moved into separate files, thus
2468       making it possible to unify the bulk of the socket implementations
2469       between Unix and Win32.
2470    
2471    3. CML's socket API changed accordingly.
2472       (Note that we need to remove non-blocking functions from this API
2473       since they are redundant in the case of CML!)
2474    
2475    4. CML's socket implementation now makes use of non-blocking functions
2476       provided by Basis, thus removing all OS-dependent code from this part
2477       of CML.
2478    
2479    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

2592    Description:
2593    
2594    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
2595    Modified config/install.bat to take advantage of it.  Also modified
2596    config/install.sh (and called it config/new-install.sh) to take advantage
2597    of it on Unix systems.  (The SML code is (supposed to be) platform-
2598    independent.)
2599    
2600    The installer can now install everything under Win32
2601    as well as under *nix as long as it compiles.
2602    
2603    Other changes:
2604    
2605      - made CML compile again under Win32
2606      - made eXene compile under Win32 (by providing a fake structure UnixSock
2607        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
2608      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
2609        same as type int;  under Win32 it isn't
2610      - fixed some slice-related problems in the win32-specific parts of CML
2611      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
2612        (under Win32, the volume name is case-insensitive, and the
2613        OS.Path code compares volume names for equality)

2638         match the new signatures.)
2639      4. MLRISC should be backward-compatible: the copies of the originals
2640         of files that needed to change under 3. were retained, the .cm files
2641         check the compiler version number and use old versions when
2642         appropriate.
2643      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
2644         dirstream -> string option (in accordance with Basis spec).
2645      6. When generating code that counts lines, ml-lex used function
2646         CharVector.foldli, taking advantage of its old interface.
2647         This has been replaced with the corresponding code from
2648         CharVectorSlice.  (html-lex must be re-lexed!)
2649      7. BitArray in smlnj-lib/Util has been extended/modified to match the
2650         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
2651      8. Removed temporary additions (fromInternal, toInternal) from the
2652         (now obsolete) IntInf in smlnj-lib/Util.
2653      9. Cleaned up structure Byte.
2654     10. Added localOffset, scan, and fromString to Date (according to spec).
2655         Cleaned/corrected implementation of Date.
2656         (Still need to check for correctness; implement better canonicalizeDate.)
2657     11. Added "scan" to signature IEEE_REAL.
2658     12. Some improvements to IntInf [in particular: efficiency-hack for
2659         mod and rem when second operand is 2 (for parity checks).]
2660     13. Changed representation of type Time.time, using a single IntInf.int
2661         value counting microseconds.  This considerably simplified the
2662         implementation of structure Time.  We now support negative time
2663         values; scan and fromString handle signs.
2664     14. Functor PrimIO now takes two additional arguments (VectorSlice and
2665         ArraySlice).

2670    Tag: blume-20030828-intinf
2671    Description:
2672    
2673    This is a major update which comes with a version number bump
2674    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
2675    and an implementation of IntInf in the Basis.
2676    
2677    There are a fairly large number of related changes and updates throughout
2678    the system:
2679    
2680    Basis:
2681            - Implemented IntInf.
2682            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
2683            - Added some missing Real64 operations, most notably Real.toLargeInt.
2684            - Added FixedInt as a synonym for Int32.
2685    
2686    compiler:
2687            * Added support for a built-in intinf type.
2688              - literals
2689              - pattern matching
2690              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
2691              - overloading on literals and operations
2692    
2693            This required adding a primitive type intinf, some additional
2694            primops, and implementations for several non-trivial intinf
2695            operations in Core.  (The intinf type is completely abstract
2696            to the compiler; all operations get delegated back to the Core.)
2697    
2698            * Intinf equality is handled by polyequal.  However, the compiler
2699            does not print its usual warning in this case (since polyequal
2700            is the right thing to do there).
2701    
2702            * Improved the organization of structure InlineT.
2703    
2704            * A word about conversion primops:
2705            If conversions involving intinf do not cancel out during
2706            CPS contract, then the compiler must insert calls to Core functions.
2707            Since all core access must be resolved already during the FLINT
2708            translate phase, it would be too late a the time of CPS contract
2709            to add new Core calls.  For this reason, conversion primops
2710            for intinf carry two arguments:  1. the numeric argument that
2711            they are supposed to convert, and 2. the Core function that
2712            can help with this conversion if necessary.  If CPS contract
2713            eliminates a primop, then the associated Core function becomes
2714            dead and goes away.  Intinf conversion primops that do not get
2715            eliminated by CPS contract get rewritten into calls of their
2716            core functions by a separate, new phase.
2717    
2718    interactive system:
2719            - Control.Print.intinfDepth controls max length of intinf constants
2720            being printed. (Analogous to Control.Print.stringDepth.)
2721            - Cleanup in printutil and pputil: got rid of unused stuff and
2722            duplicates; replaced some of the code with code that makes better
2723            use of library functionality.
2724    
2725    CM:
2726            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
2727            are no longer silent.
2728    
2729    CKIT:
2730            Fixed mismatched uses of Int32 and LargeInt.  I always decided
2731            in favor of LargeInt -- which is now the same as IntInf.
2732            CKIT-knowledgable people should check whether this is what's
2733            intended and otherwise change things back to using Int32 or
2734            FixedInt.
2735    
2736    Throughout the code:
2737            Started using IntInf.int literals and built-in operations
2738            (e.g., comparison with 0) where this seems appropriate.

2758    Description:
2759    
2760    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
2761    
2762        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
2763    
2764    This patch restores SML/NJ's ability to run under win32.  There are a
2765    number of changes, including fixes for several bugs that had gone
2766    unnoticed until now:
2767    
2768      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
2769        trying to run the win32 version from within cygwin.)
2770    
2771      - There are a number of simple .bat scripts that substitute for their
2772        corresponding Unix shell-scripts.  (See below.)
2773    
2774      - The internals of ml-build have been modified slightly.  The main
2775        difference is that instead of calling ".link-sml" (or link-sml.bat)
2776        using OS.Process.system, the ML process delegates this task back
2777        to the script.  Otherwise problems arise in mixed environments such
2778        as Cygwin where scripts look and work like Unix scripts, but
2779        where OS.Process.system cannot run them.
2780    
2781      - In CM, the srcpath pickler used native pathname syntax -- which
2782        is incorrect in the case of cross-compilation.  The new pickle format
2783        is independent of platform-specific naming conventions.
2784    
2785      - Path configuration files (such as lib/pathconfig) can now choose
2786        between native and standard syntax.  Placing a line of the form
2787    
2788            standard!
2789    
2790        into the file causes all subsequent paths to be interpreted using
2791        CM standard pathname syntax (= Unix conventions); a line
2792    
2793            native!
2794    
2795        switches back to native style.  This was needed so that
2796        path config files can be written portably, see src/system/pathconfig.
2797    
2798      - Runtime system:
2799    
2800          - win32-filesys.c:  get_file_time and set_file_time now
2801            access modification time, not creation time.
2802    
2803          - I/O code made aware of new array representation.
2804    
2805          - Bug fixes in X86.prim.masm.
2806    
2807       - src/system/makeml made aware of win32. (For use under cygwin
2808            and other Unix-environments for windows.)
2809    
2810       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
2811         which caused BinIO.inputAll to fail consistently.
2812    
2813    .bat scripts:
2814    
2815       Windows .bat scripts assume that SMLNJ_HOME is defined.
2816    
2817       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
2818         applications (sml, ml-yacc, ml-lex).
2819       - ml-build.bat: analogous to ml-build.
2820       - config\install.bat:  Analogous to config/install.sh.  This requires
2821         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
2822         (nmake etc. must be on the path, and vcvars32 must have been run.)
2823         Moreover, sources for ml-lex and ml-yacc need to exist under src,
2824         and the bootfile hierarchy must have been unpacked under
2825         sml.boot.x86-win32.
2826         The script is very primitive and does a poor job at error checking.
2827         It only installs the base system, ml-lex, and ml-yacc.  No other
2828         libraries are being installed (i.e., you get only those that
2829         are part of the compiler.)
2830       - link-sml.bat:  analogous to .link-sml, but not currently used
2831    
2832    Unrelated bug fixes:
2833    
2834      - ml-nlffigen now exports structures ST_* corresponding to incomplete
2835        types.
2836      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
2837        otherwise.)

2865      1. Added a flag for controlling whether non-exhaustive bindings will
2866         be treated as errors (default is false).
2867      2. Cleaned up the *entire* source tree so that CMB.make goes through
2868         without a single non-exhaustive match- or bind warning.

2875    
2876    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
2877    
2878       This mainly affects the quality of error messages.  However, some
2879       of the code is now more straightforward than before. (Treatment of
2880       the above four constructs in translate.sml is much simpler than
2881       the "macro-expansion" that was going on before.  Plus, the mach-
2882       compiler no longer gets invoked just to be able to compile an
2883       if-expression.)
2884    
2885    2. The ErrorMsg.Error exception is now caught and absorbed by the
2886       interactive loop.

2892    Description:
2893    
2894        Ported the runtime system to cygwin, which uses the unix
2895    x86-unix bin files.  Missing/buggy features:
2896    
2897       o getnetbyname, getnetbyaddr: these functions seem to be missing in
2898         the Cygwin library.
2899       o Ctrl-C handling may be flaky.
2900       o Windows system calls and Windows I/O are not supported.
2901    
2902       A new set of binfiles is located at:
2903    
2904         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
2905    
2906       This is only needed for bootstrapping the cygwin version of smlnj.
2907       Other x86 versions can use the existing binfiles.

2937    110.37 and 110.38.)
2938    There was another set of potential problems related to the handling of

2966    
2967    In good old tradition, there has been a slight hiccup so that we have
2968    to patch 110.42 after the fact.   The old release tag has been replaced
2969    (see below).
2970    
2971    The change solves a problem with two competing approaches the
2972    configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
2973    each other's way.
2974    
2975    This change only affects the runtime system code and the installer script.

3058    Description:
3059    
3060    I back-ported my implementation of IEEEReal.fromString from the
3061    idlbasis-devel branch so that we can test it.
3062    
3063    Another small change is that ppDec tries to give more information
3064    than just "<sig>" in the case of functors.  However, this code is
3065    broken in some mysterious way if the functor's body's signature
3066    has not been declared by ascription but gets inferred from the
3067    implementation.  This needs fixing...

3120    - John tweaked runtime to be silent on heap export (except when
3121      GC messages are on).

3123      config/preloads (as suggestions).

3130    
3131    - Added ControlUtil structure to control-lib.cm.
3132    - Use it throughout.
3133    - Used Controls facility to define MLRISC controls (as opposed to
3134      registering MLRISC control ref cells with Controls after the fact)
3135    - Fixed messed-up controls priorities.
3136    
3137    * Removed again all the stuff from config/preloads that one wouldn't
3138      be able to preload at the time the initial heap image is built.
3139      (Many libraries, e.g., CML, do not exist yet at this time.  The
3140       only libraries that can be preloaded via config/preloads are those
3141       that come bundled with the bootfiles.)

3166    Description:
3167    
3168    0. John Reppy made several modifications to the SML/NJ library.
3169       In particular, there is a shiny new controls-lib.cm.
3170    
3171    1. Pushed new controls interface through compiler so that everything
3172       compiles again.
3173    
3174    2. Added FormatComb and FORMAT_COMB to the CML version of the
3175       SML/NJ library (so that CML compiles again).
3176    
3177    3. Modified init scripts because XXX_DEFAULT environment variables
3178       are no longer with us.  (Boot-time initialization is now done
3179       using the same environment variables that are also used for
3180       startup-time initialization of controls.)

3186    Description:
3187    
3188            All pseudo-ops emitted before the first segment declaration
3189    such as TEXT, DATA, and BSS directives are assumed to be global
3190    declarations and are emitted first in the assembly file. This is
3191    useful in a number of situations where one has pseudo-ops that are not
3192    specific to any segment, and also works around the constraint that one
3193    cannot have client pseudo-ops in the TEXT segment.
3194    
3195            Because no segment is associated with these declarations it is
3196    an error to allocate any space or objects before the first segment
3197    directive and an exception will be raised. However, we cannot make
3198    this check for client pseudo-ops.
3199    
3200            These top level declarations are a field in the CFG graph_info.
3201    In theory you can continue to add to this field after the CFG has been
3202    built -- provided you know what you are doing;-)

3210    A few minor bugfixes:
3211    
3212      - Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
3213        (Bogus printouts for redefined bindings still occur.  Compiler
3214        bug should no longer occur now.  We need to redo the prettyprinter
3215        from scratch.)
3216    
3217      - CM pathname printer now also adds escape sequences for ( and )
3218    
3219      - commend and docu fixes for ml-nlffi

3225    Description:
3226    
3227    Applied the following bugfix provided by Emden Gansner:
3228    
3229        Output is corrupted when outputSubstr is used rather than output.
3230    
3231        The problem occurs when a substring
3232    
3233            ss = (s, dataStart, dataLen)
3234    
3235        where dataStart > 0, fills a stream buffer with avail bytes left.
3236        avail bytes of s, starting at index dataStart, are copied into the
3237        buffer, the buffer is flushed, and then the remaining dataLen-avail
3238        bytes of ss are copied into the beginning of the buffer. Instead of
3239        starting this copy at index dataStart+avail in s, the current code
3240        starts the copy at index avail.
3241    
3242        Fix:
3243        In text-io-fn.sml, change line 695 from
3244             val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3245        to
3246             val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

3262    Description:
3263    
3264    Added full support for div/mod/rem/quot on the x86, using the machine
3265    instruction's two results (without clumsily recomputing the remainder)
3266    directly where appropriate.
3267    
3268    Some more extensive power-of-two support was added to the x86 instruction
3269    selector (avoiding expensive divs, mods, and muls where they can be
3270    replaced with cheaper shifts and masks).  However, this sort of thing
3271    ought to be done earlier, e.g., within the CPS optimizer so that
3272    all architectures benefit from it.
3273    
3274    The compiler compiles to a fixed point, but changes might be somewhat
3275    fragile nevertheless.  Please, report any strange things that you might
3276    see wrt. div/mod/quot/rem...

3282    Description:
3283    
3284    Fixed my broken div/mod logic.  Unfortunately, this means that the
3285    inline code for div/mod now has one more comparison than before.
3286    Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3287    The problem was with quotient = 0, because that alone does not tell
3288    us which way the rounding went.  One then has to look at whether
3289    remainder and divisor have the same sign...  :(
3290    
3291    Anyway, I replaced the bootfiles with fresh ones...

3298    
3299    NEW BOOTFILES!!!    Version number bumped to 110.39.3.
3300    
3301    Primops have changed. This means that the bin/boot-file formats have
3302    changed as well.
3303    
3304    To make sure that there is no confusion, I made a new version.
3305    
3306    
3307    CHANGES:
3308    
3309    * removed REMT from mltree (remainder should never overflow).
3310    
3311    * added primops to deal with divisions of all flavors to the frontend
3312    
3313    * handled these primops all the way through so they map to their respective
3314      MLRISC support
3315    
3316    * used these primops in the implementation of Int, Int32, Word, Word32
3317    
3318    * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3319    
3320    * parameterized INLMIN, INLMAX, and INLABS by a numkind
3321    
3322    * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3323      floating point
3324    
3325    * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3326      and Real (but Real.abs maps to a separate floating-point-only primop)
