170    - Aaron: fixed a number of bugs in ml-ulex.
171    - Matthias:
172       - added CM control "cm.force-tools"; this is false by default;
173         when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
174         will be forced to run regardless of whether or not their targets
175         are up-to-date
176       - changed installer code so that config/install.sh will re-build
177         heap images for all tools even if those heap images already existed

183    
184    After Aaron Turon's bug fix for ml-ulex (handling the ^ character
185    in legacy mode), re-ran the lexer generator on all lex input files
186    and committed the results.
187    
188    This should fix the problem with ckit and nlffi that was reported
189    by Vesa A. Norrman.

204    
205    3rd merge of base from primop-branch-3 into the trunk.
206    Additional bug fixes included:
207    
208     * Timer.cpu_timer, etc. type printing corrected (by making
209         Timer have opaque sig constraint in basis/Implementation/timer.sml)
210     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by

216    Description:
217    
218    Fixed some bugs in new Div code in FLINT/trans/translate.sml.
219    
220    Also, changed the handling of "no core access":  When translate.sml
221    needs access to a core exception at a time when the core has not
222    been set up yet (this only happens when compiling system/smlnj/init/*),
223    then don't bother generating the corresponding tests.
224    
225    The old scheme was to generate a bogus value to be used in place of
226    the exception.  Unfortunately, that confuses the plambda type checker.
227    Moreover, it does not do any good, because at runtime we don't expect
228    such an exception to be ever raised.  (The code in system/smlnj/init/*
229    has to be written very carefully with this in mind!)

241    Description:
242    
243    FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
244    with an explicit test for zero division.  This should fixes several
245    regressions and makes it possible for downstream optimization phases
246    to treat these operations as "pure" when they are applied to unsigned
247    operands.

254    Added the new MLRISC code generator for the AMD64.  This version,
255    in contrast to the previous one, uses SSE registers and instructions
256    for all floating-point computations.

262    
263    A number of fixes related to the formatting of dates.  These include fixes
264    for bugs #1415 and #1416.  We also now correctly handle format characters that
265    lie outside the specified set.

270    Description:
271    
272    CMB (and CM) now automatically defines the CM "preprocessor" symbol
273    NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
274    
275      (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
276       CM_SLAVE_MODE is defined in attached slaves while running CM.make
277       or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
278       while running CMB.make.  The point is that the single symbol
279       NO_PLUGINS is definde in all three cases.)
280    
281    I changed the three locations within the sources that get compiled
282    during CMB.make where ml-yacc or ml-lex input is processed: When
283    NO_PLUGINS defined, then the use of the mlyacc and mllex tools
284    is bypassed.
285    
286    When bootstrapping new versions of the compiler, there can be
287    situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
288    are not available or otherwise not operational.  In this case one can
289    manually define the NO_PLUGINS symbol prior to running CMB.make().  To
290    do so, the following command should be issued at the interactive
291    prompt:
292    
293       #set (CMB.symval "NO_PLUGINS") (SOME 1);
294    
295    A CMB.make with NO_PLUGINS defined relies on the existence of the
296    files that normally would be generated by ml-yacc and ml-lex.
297    (Copies of these files are in the repository.)

305    2nd merge of base from primop-branch-3 into the trunk.

313    Description:
314    
315    Changed the installation mechanism for CM tool plugins.  These are
316    just libaries and now get installed like ordinary libaries.
317    
318    There are now a number of new installation targets that give some
319    fine-grain control over what classes and suffixes are known, and what
320    they will map to.
321    See config/targets for details.
322    
323    The code that caused plugin installation as part of running a
324    tool's "build" script has been removed.  (The build script is for
325    building, not for installing.)

330    Description:
331    
332    Added a boolean control named cm.tolerate-tool-failures (env. variable
333    name: CM_TOLERATE_TOOL_FAILURES).  The default is false and makes
334    CM fail if a shell tool reports a non-success exit status.  If
335    the control is set to true, then CM will press on after tool failures
336    in the event that the target files exist (even though they are
337    considered outdated).  Turning the control to true can be useful for
338    bootstrapping.

342    Date: 2007/05/19
343    Description:
344    
345    Merge of ml-lpt revisions for 110.64.
346    
347    The name of several ml-lpt-lib modules has changed:
348      Repair        => AntlrRepair
349      StreamPos     => AntlrStreamPos
350      ErrHandlerFn  => AntlrErrHandler
351      EBNF          => AntlrEBNF
352    
353    The ml-antlr specification format has changed: declarations such as
354    %tokens and nonterminal definitions can occur *multiple* times in the
355    same specification.  The semantics are such that each new declaration
356    extends the previous ones.  This does not apply to %start or %name,
357    of course.
358    
359    Importing a grammar via %import now includes *all* declarations in from
360    the imported grammar, except for %name, %entry, and %start.  Tokens
361    and nonterminals can be dropped using the new %dropping clause of the
362    %import directive; the separate %drop and %extend have been removed.
363    
364    We now allow optional type annotations on nonterminals, using the %nonterms
365    directive as in ml-yacc.
366    
367    The refcell construct is now implemented using SML's regular reference
368    cells, so the :== and !! notation has been deprecated.
369    
370    The ml-antlr tool now does much more checking of specifications, and
371    its error messages have been greatly improved.  Error repair for
372    generated parsers has been completely rewritten, and is now both
373    much faster and more accurate.
374    
375    ml-ulex is now more lenient with escape codes (non-SML-standard
376    escape codes are now interpreted literally, so e.g. \| denotes "|").
377    Also, character classes may now include a "-" character at the beginning
378    as is standard in most other regexp tools.
379    
380    All of these changes are documented in the user guide, which has
381    been updated and improved with this merge.

533    
534    Added preliminary support in MLRISC for Staged Allocation, a technique
535    for specifying calling conventions (see
536    http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
537    Initially, we plan to use this code to generate C calls for the AMD64.
538    
539    The staged allocation code base resides in MLRISC/staged-allocation,
540    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

606    
607    Brought ml-lpt manual up-to-date with the code.  Many minor
608    improvements to the tools, and a few minor bugfixes.  Prepared
609    ml-lpt-lib for integration with new UTF8 structure.  Changed
610    the interface for creating streams in ml-ulex (we now support
611    stream creation from several kinds of sources).  Overall, the
612    tools are now quite stable, and their interfaces are unlikely to
613    change in a way that would break compatibility.  More work,
614    however, is needed in the documentation.

620    
621    Implemented library installer.  Moved CM plugin code for
622    ml-burg, ml-lex, and ml-yacc out of CM source tree and into
623    their respective trees.  Implemented CM plugin for ml-ulex
624    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
625    and ml-antlr.
626    
627    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
628    CM tools.  (It turns out to be too messy to do otherwise because
629    there is too much code that during installation relies on the presence
630    of these tools -- resulting in a tricky ordering problem.)

637    Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
638    Modified CM's startup code to use shiftArgs as it processes
639    command line arguments.  This way, the init code in each .sml-file
640    or library that is mentioned at the top level will see only
641    those arguments that have not yet been processed at this point.
642    In other words, the init code can "seize control" and process the
643    remaining command line.

710    Description:
711    
712    Added code to CM's "standard shell tool" implementation which
713    causes it to tolerate (with a warning) the situation where the shell
714    command fails (e.g., due to the shell command's non-existence)
715    as long as all target files exist.
716    
717    This makes it possible to, e.g., build ml-yacc from sources even if
718    svn checkout messed up the time stamps on files in such a way that
719    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
720    be needed to re-process yacc.grm, but obviously it might not yet be
721    available at that time.)

761    Description:
762    
763    New working release (110.60).  NEW BOOTFILES!
764    
765    This is the first subversion-hosted release.  There are also changes
766    to the directory layout.  Here is a table:
767    
768    (All pathnames are relative to the SML/NJ "root" directory.)
769    
770      config -> config
771    
772      src/cm -> base/cm
773      src/compiler -> base/compiler
774      src/runtime -> base/runtime
775      src/system -> base/system
776    
777      src/cm/pgraph -> pgraph
778    
779      src/READMES -> base/READMES
780      src/$notefile -> base/NOTES/$notefile
781         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
782                           MACOSXINSTALL WININSTALL
783    
784      src/smlnj-lib -> smlnj-lib
785      src/MLRISC -> MLRISC
786      ckit -> ckit
787      src/cml -> cml
788      src/eXene -> eXene
789      src/heap2asm -> heap2asm
790      src/lexgen -> lexgen
791      src/ml-burg -> ml-burg
792      src/ml-lex -> ml-lex
793      src/ml-yacc -> ml-yacc
794      src/ml-nlffi-lib -> nlffi/lib
795      src/ml-nlffigen -> nlffi/gen
796      src/smlnj-c -> smlnj-c
797      src/tools/TraceDebugProf -> trace-debug-profile
798    
799    In addition, there is also a new
800    
801      ml-lpt
802    
803    directory containing two new program generator tools: ml-ulex and
804    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
805    LL(k) parser generator). These tools are currently "beta-quality"
806    
807    The latest versios of the sources can now be obtained anonymously
808    via subversion.  For this, it is useful to first check out
809    
810       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
811    
812    and put the resulting directory on your shell's PATH.  This provides
813    access to three shell scripts: checkout-all.sh, stat-all.sh,
814    and refresh-all.sh.
815    
816    To create a freshly checked-out copy of the sources, do
817    
818       checkout-all.sh [dir]
819    
820    where dir is the optional SML/NJ root directory (default is ".").
821    
822    This creates the above directory layout.  Each subdirectory of
823    the root is under individual subversion control.  The stat-all.sh
824    and refresh-al.sh scripts apply "svn stat" or "svn update" to
825    each of these subtrees.
826    
827    ----------------------------------------------------------------------
828    Name: Matthias Blume (http://www.tti-c.org/blume/)
829    Date: 2006/11/02 12:20:00 CST
830    Description:
831    
832    Reorganized directory layout.
833    
834    This is a temporary solution, more reorganization is to come.
835    
836    The basic idea is to have a number of toplevel trees, each corresponding
837    to a well-defined part of the overall system.  Each part can be
838    maintained individually, even in separate source repositories,
839    although currently we still serve everything out of the main
840    smlnj-gforge tree.
841    
842    Installer and and scripts have been updated to reflect the new
843    layout.  The installer (base/src/system/smlnj/installer) is now
844    "scriptable" to avoid burning too much knowledge about the
845    layout into SML source code.  The main script used by the installer
846    is in config/actions.
847    
848    The main change is that many of the subdirectories of what used to
849    be known as "src" have moved to the toplevel.  The "src" directory
850    itself has moved down into a subtree called "base".  (We may eventually
851    get rid of the extra level of indirection represented by "src".)
852    
853    The layout is now as follows:
854    
855      toplevel tree name | default repository
856                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
857      -------------------+----------------------------------------------------
858      config             | $gf/config/trunk
859                         |
860      base               | $gf/sml/trunk
861                         |
862      smlnj-lib          | $gf/smlnj-lib/trunk
863      MLRISC             | $gf/MLRISC/trunk
864                         |
865      ml-yacc            | $gf/ml-yacc/trunk
866      ml-lex             | $gf/ml-lex/trunk
867      ml-burg            | $gf/ml-burg/trunk
868      lexgen             | $gf/lexgen/trunk
869      heap2asm           | $gf/heap2asm/trunk
870                         |
871      cml                | $gf/cml/trunk
872      eXene              | $gf/eXene/trunk
873      ckit               | $gf/ckit/trunk
874      nlffi              | $gf/nlffi/trunk
875                         |
876      smlnj-c            | $gf/smlnj-c/trunk
877    
878    In $gf/admin there are a few useful shell scripts for checking out
879    and maintaining the entire collection of trees:
880    
881       admin/checkout-all.sh [dir]
882          -- optionally creates dir and checks out all trees from their
883             default repositories; if dir is missing, checkout into .
884       admin/refresh-all.sh [dir]
885          -- looks at all trees (from the above list) in dir (default: .)
886             and runs "svn update" if the tree exists and is under
887             subversion control;
888             non-existing or non-subversion trees are skipped
889       admin/stat-all.sh [dir]
890          -- like refresh-all.sh, but runs "svn stat" instead

934    Description:
935    
936    Implemented ml-makedepend (i.e., CM.sources) in a better (more robust)
937    way.  This should hopefully fix the ml-makedepend problem permanently.

943    Description:
944    
945    Fixed long-standing bug with ml-makedepend where it would output a
946    spurious dependency to a non-existing file.  (This is a simple fix.
947    It might need further looking into.)

1038    Hooked code for Darwin-specific Intel ABI into main compiler.
1039    (This is a temporary solution which relies on the fact that the
1040    compiler itself does not use NLFFI.  Eventually we need to divorce
1041    intel mac from generic x86 unix code and make separate sets of binaries.)

1070    Description:
1071    
1072    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
1073    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
1074    at the time when config/preloads is processed, the library has to
1075    be referred to by another name.  In 110.57 this would be
1076    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
1077    to be valid as well.)
1078

1132    Tag: blume-22051115-versiontool
1133    Description:
1134    
1135    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
1136    file gets loaded as a tool -- by the equivalent of CM.make during the
1137    run of CMB.make.  Thus, CMB's path configuration is meaningless for
1138    it.  Instead, it has the status of "user code", so it should use
1139    $/basis.cm to refer to the Basis library.  (At least that's true for
1140    the purpose of bootstrapping the previous change.  In the future it
1141    might make sense to have versiontool.cm refer to
1142    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1143    compiler itself uses.)
1144    
1145    Also patched src/system/testml to have it activate those extra anchor
1146    bindings in config/extrapathconfig.

1151    Tag: blume-22051115-libraries
1152    Description:
1153    
1154    This change affects the way the following libraries are tied into
1155    the system:
1156    
1157       $/basis.cm
1158       $/smlnj-lib.cm
1159       $/pp-lib.cm
1160       $/controls-lib.cm
1161       $/html-lib.cm
1162       $/ml-yacc-lib.cm
1163    
1164    These libraries are now internally (as seen from the source code
1165    of the implementation itself) known by the following names:
1166    
1167       $smlnj/basis/basis.cm
1168       $smlnj/smlnj-lib/smlnj-lib.cm
1169       $smlnj/smlnj-lib/pp-lib.cm
1170       $smlnj/smlnj-lib/controls-lib.cm
1171       $smlnj/smlnj-lib/html-lib.cm
1172       $smlnj/ml-yacc/ml-yacc-lib.cm
1173    
1174    This makes it possible to work with code that requires different
1175    versions of these libraries, and which refers to these libraries using
1176    their "default" names (i.e., the first set of names above).  In other
1177    words, one can un-define or re-define those default names without
1178    compromising the proper functioning of the compiler itself.
1179    
1180    A similar procedure had already been performed for several of the
1181    MLRISC libraries that are linked into the compiler.  I did some
1182    cleanup on this code.
1183    
1184    A new file in the config directory (named extrapathconfig) is
1185    responsible for setting up path anchors that the compiler itself does
1186    not need, but that are typically required by user code.

1374    heap does not return to the caller of CM.redump_heap but
1375    restarts the interactive system from scratch.  The original call of
1376    CM.redump_heap does not return but ends the interactive session.
1377    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1378    
1379    Internally, redump_heap winds the dynamic execution context back to
1380    the point where the original heap image was created and re-executes
1381    the heap image generation code in the boot code.

1498    Description:
1499    
1500    Implemented new (but still experimental) heap2exec facility.  This is
1501    tested under Mac OS X and should work under Linux (will test shortly).
1502    It will probably also work on the Sparc (will test some time later).
1503    
1504      - removed old "HACKED_STANDALONE" hack from runtime
1505    
1506    To be able to test this, uncomment the request for "heap2asm" in
1507    config/targets prior to installation.  (Notice that this is different
1508    from "heap2exec" mentioned below.  Not a typo.)
1509    
1510    To perform an actual test, run the command
1511    
1512       $ bin/heap2exec heapfile execfile
1513    
1514    (You can put heap2exec on your shell's path.)
1515    
1516    For example, run
1517    
1518      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1519    
1520    This will create a standalone executable called "mly" which you can
1521    then invoke directly as a command.

1666    Tag: blume-20041124-position
1667    Description:
1668    
1669    The compiler can now be compiled in a mode that makes structure Position
1670    equal to Int64.  The default, however, is unchanged (Position = Int31)
1671    for the time being.
1672    
1673    To enable 64-bit positions, use the following procedure:
1674    
1675    1. Start sml
1676    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1677    3. Type
1678          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1679    4. Run CMB.make() as usual.
1680    
1681    This is barely tested.  The only test so far was a little SML program
1682    counting the number of characters in an 8-gigabyte file by
1683    reading it character-by-character.  That test was successful.
1684    
1685    In support of 64-bit positions, a number of new functions have been
1686    added to the runtime system.

1731    
1732    - In a previous commit, fixed a minor issue with how polyequal is being
1733      translated.  In particular, the code now "looks through" abstractions.
1734      This results in slightly fewer polyEqual warnings and hopefully slightly
1735      more efficient code.  Important examples for where this matters are
1736      the new int64 and word64 types.

1756    32-bit wide.)

1759    are still missing.

1765    Description:
1766    
1767    Structure Word64 is now (almost) complete, word literals and patterns
1768    seem to work.  There are a few odd pieces missing.  In particular,
1769    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1770    at the moment.
1771    
1772    Making Word64 official would mean that LargeWord becomes Word64.  But
1773    this requires extreme care because most word-word conversions have to
1774    go through LargeWord, so making a mistake means loss of efficiency or
1775    worse.  Eventually there will be a solution similar to (but actually
1776    simpler than) what I did with IntInf.

1808      - Changend config/srcarchiveurl from a file just
1809        containing the URL string into a file containing
1810        shell script code.  The code has access to the $VERSION variable.
1811      - Made corresponding changes to config/install.sh and config/unpack.
1812      - Default contents of config/srcarchiveurl uses $VERSION and
1813        normally does not have to be edited to reflect a version change.
1814    
1815      (As a result, a version change can be done by just editing
1816       config/version, the rest is now automatic.)

1856    Tag: blume-20041020-standalone-backtrace
1857    Description:
1858    
1859    Added a mechanism for getting back-trace information from standalone
1860    programs.  Here is how it works:
1861    
1862       1. The part of the program from which you want to get backtrace
1863          information (usually the whole program) should be wrapped with
1864          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
1865          main program could be modified from something like
1866    
1867             fun main (pgm, args) = ...
1868    
1869         to
1870    
1871            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1872    
1873       2. To be able to access BackTrace.monitor, you have to add
1874          library $smlnj-tdp/plugins.cm to the .cm file that contains your
1875          main function.
1876    
1877       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1878          CM might have created in the past for your project).
1879    
1880       4. Build the system using this command line:
1881    
1882             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1883                      myprog.cm MyProg.main myprog
1884    
1885          instead of the usual
1886    
1887             ml-build myprog.cm MyProg.main myprog
1888    
1889    I changed a library name:
1890    
1891       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1892    
1893    New libraries:
1894    
1895       $smlnj-tdp/back-trace.cm
1896          -- when loaded causes the back-trace plugin to be installed
1897       $smlnj-tdp/coverage.cm
1898          -- when loaded causes the coverage plugin to be installed

1914    Description:
1915    
1916    * Test coverage tool added!
1917    * Further reorganization of tracing-, debugging-, and profiling support:
1918    
1919        - moved original BTImp -- now called BackTrace -- into a separate
1920          library called $/trace-debug-profile.cm
1921        - eliminated all mentions of BTrace from SMLofNJ.Internals
1922        - only the instrumentation mechanism is now left in the compiler proper
1923        - BackTrace module is a plugin which is NOT plugged in by default
1924        - Coverage module is another such plugin
1925    
1926    To get the benefits of any of these plugin modules, the code in
1927    question must be compiled with tdp instrumentation turned on.  This
1928    can be done by setting SMLofNJ.Internals.TDP.mode to true.
1929    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1930    
1931    Plugins are selected at link time.  (Pre-compiled instrumented code
1932    can be re-loaded with different plugins in effect.)  When an
1933    instrumented module is linked, whatever plugins are at that time
1934    enabled will come into effect for that module.
1935    
1936    To enable the back-trace plugin, load library $/trace-debug-profile.cm
1937    and invoke BackTrace.install() (e.g., from the interactive prompt).
1938    To enable the coverage plugin, load the same library and invoke
1939    Coverage.install().
1940    
1941    Back-traces are generated automatically on uncaught exceptions and
1942    when the code in question explicitly invokes BackTrace.trigger().
1943    
1944    Coverage (and execution frequency-) information must be queried
1945    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

1967    This is is preparation of using the original back-trace
1968    instrumentation for other purposes.  "TDP" stands for
1969    Trace/Debug/Profile.
1970    
1971    The control flag controlling whether instrumentation is on or off is now
1972    registered under a different name, so instead of running sml as
1973    
1974     sml -Cinstrument.btrace-mode=true
1975    
1976    one has to say
1977

1998    "*", and "-" as ordinary identifiers rather than keywords.
1999    
2000    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
2001    is supposed to accept a tool argument called "source", but this did
2002    not work because of the clash with the keyword.

2046    
2047    * Moved the "version" magic into its own little library under

2049      a stable src/compiler/core.cm.
2050    
2051    * At the same time, structure CompilerVersion is now known as
2052      structure SMLNJVersion.
2053    
2054    * Arranged for the version tool to NOT kick in when rebuilding the system
2055      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
2056      Also, loading the versiontool does not work when rebuilding the system
2057      because CM is not properly initialized at that time.

2062    Tag: blume-20040929-autoversion
2063    Description:
2064    
2065    Implemented some CM magic to have
2066        file src/compiler/TopLevel/main/version.sml
2067    generated automagically.
2068    The version is taken from two files: config/version and config/release.
2069    The first is expected to contain a two-part version number such as 110.49.
2070    The second should contain a single number, but it may be missing.
2071    
2072    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2073    time the version tool is loaded (which is the first time you say CMB.make),
2074    then the tool will increment the value stored in config/release every
2075    time CMB.make is invoked.
2076    
2077    The binfile format is now insensitive to anything beyond the first
2078    two components of a version number, so bumping the release does not render
2079    binfiles incompatible.  Auto-bumping can be used to keep track of versions
2080    during development without invalidating existing binfiles.
2081    
2082    In any case, every CMB.make updates the date information in version.sml.
2083    (This is the date that is printed in the banner.)

2096    Tag: blume-20040927-controls
2097    Description:
2098    
2099    Added two pieces of functionality to the Controls interface:
2100    
2101    1.   val save'restore: 'a control -> unit -> unit
2102    
2103       grabs the current value of the control in stage 1 and restores it
2104       in stage 2.
2105    
2106    2.   val set' : 'a control * 'a -> unit -> unit
2107    
2108       stores the given value into the control in stage 2 (i.e., delayed)
2109       but does all error checking in stage 1.
2110       (This is for string controls that need to do parse their argument --
2111        something that might fail.  In some cases, notably in CM, one
2112        already knows the intended argument but wants to delay the actual
2113        assignment until a time when error recovery would be more difficult.)
2114    
2115    Changed the handling of controls in tool arguments to classes "sml" and
2116    "lazysml":
2117       - use Controls.save'restore as a more robust way of restoring the
2118         old value (in particular: without having to re-parse the string)
2119       - use controls to handle the "overload" keyword in the init group
2120         (I believe this change actually fixes a long-standing obscure bug.)

2125    Tag: blume-20040927-lazysml
2126    Description:
2127    
2128    Added a new tool class called "lazysml" to CM's tool chest.  The only
2129    difference to "sml" is that compilation is done with Control.lazysml
2130    set to true.  A source of class "lazysml" is automatically recognized
2131    by a file name suffix of ".lml".
2132    
2133    In addition to the above feature, the original class "sml" now also
2134    supports a tool argument "lazy" which has the same effect.  As a
2135    result, the following three lines are equivalent:
2136    
2137        foo.sml : lazysml
2138        foo.sml : sml (lazy)
2139        foo.sml (lazy)
2140    
2141    The setting goes into effect both during parsing and during
2142    compilation.  The original setting is restored right after parsing and
2143    after compilation, respectively.
2144    
2145    In addition to all the above, there is also a general mechanism to set
2146    ANY of the "controls" that are available at the command line via
2147    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
2148    apply as well. (In fact, "lazy" is implemented as a special case of
2149    the general mechanism.)
2150    
2151    The .cm file syntax uses a new keyword tool argument called "with".
2152    There are several ways of indicating the desired settings:
2153    
2154        foo.sml (with:parser.quotations=true)
2155        foo.sml (with:(name:parser.quotations value:true))
2156        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2157        foo.sml (with:(name1=value1 name2=value2 ...))
2158        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2159    
2160        etc.
2161    
2162    Another possible abbreviation is to leave out the =v or value:v part
2163    if the name refers to a boolean control (in which case the value is
2164    taken to be true).  Thus, one could get lazy sml also by saying:
2165    
2166        foo.sml (with:parser.lazy-keyword=true)
2167        foo.sml (with:parser.lazy-keyword)
2168        foo.sml (with:(name:parser.lazy-keyword value:true))
2169        foo.sml (with:(name:parser.lazy-keyword))

2266      fails (i.e., when source and target are on different file systems);
2267      the code compiles but has yet to be tested in anger

2521    Description:
2522    
2523    Changed the interface of structures Timer and Unix to match the most
2524    recent Basis spec.
2525    
2526    In the case of Unix there still seems to be an open/weird issue:
2527    
2528       The {text,bin}{In,Out}streamOf functions are supposed to create
2529       fresh streams whenever they are called -- as opposed to have them
2530       return the same stream every time.  This design is supposed to
2531       prevent space leaks caused by proc values hanging on to streams.
2532    
2533       The reap function, on the other hand, is supposed to close the
2534       streams.  This cannot be done without having a handle on the
2535       stream in proc after all...
2536    
2537    I took the liberty to implement the following stopgap solution:
2538    
2539      The proc value hangs on to the most recently created stream(s).
2540      Reap closes those.  If either or both of the two streams hadn't
2541      been created at all yet, then reap will close the corresponding
2542      file descriptors directly.
2543    
2544    PS: I don't understand the original space leak argument anymore.  If
2545    a proc hangs on to the imperative stream, then I/O operations on those
2546    will advance the state of the cached stream and avoid the space leak.

2560    Description:
2561    
2562    CM now ignores (but still accepts) the "owner" information in group
2563    descriptions.  The owner of a group is its next enclosing
2564    library. Each group must have a unique owner.  (There is a virtual
2565    "toplevel" library that owns groups which are not nested within a real
2566    library.)  Previously, each group had to explicitly declare its owner,
2567    and CM would check that such a declaration is correct.  The new scheme
2568    is to have CM check that for each group there is precisely one owning
2569    library.
2570    
2571    The advantage of the new scheme is that the programmer no longer needs
2572    to maintain the somewhat annoying owner information.  The downside is
2573    that CM cannot enforce the ownership rule across multiple runs of
2574    CM.make.  Fortunately, enclosing the same group in two different
2575    libraries A and B which are not part of the same program does not
2576    cause real problems.

2596    
2597    Arranged for ml-build to clean up after itself a little bit better.
2598    The script generates a temporary SML source file and compiles it using
2599    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
2600    gets rid of those at the end, so they don't accumulate under .cm.
2601    
2602    This required a minor change to install.sh because the name of the
2603    metadata directory (default: .cm) is actually configurable at
2604    installation time.

2619    Description:
2620    
2621    Added previously missing support for many socket-related functions
2622    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
2623    for the voluminous patch!
2624    
2625    (I have not tested this patch under win32 yet.)
2626    
2627    Here is David's e-mail:
2628    
2629    Hi,
2630    
2631    Attached to this email you find a diff against sml/nj 110.45
2632    that will enable socket support under Windows.
2633    
2634    To apply the patch (using unix or cygwin)
2635    1) gunzip runtime.diff.gz
2636    2) "cd" into "src/runtime" in the source tree of a fresh
2637       110.45 installation.
2638    3) patch -p 1 < [your/path/to]runtime.diff
2639    
2640    The code compiles fine but has NOT yet been extensively tested.
2641    I only ran a few tests for basic socket client functionality
2642    (which worked fine).  Especially the functions that use ioctl
2643    are not tested at all and might not work (see below).
2644    
2645    I implemented this since we want to move to a newer version of sml/nj
2646    but need socket support in order to use it.  This is the first time I
2647    even had a look at the sml/nj source,  so please review my changes
2648    before making this part of the distribution!  Here are a few issues
2649    that I think might be better for someone to solve who is more
2650    familiar with the sml/nj source (and socket programming):
2651    
2652    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2653      exception since I could not figure out what the windows equivalent
2654      of these functions is
2655    
2656    - In sockets-osdep.h there are a some #include statements that are
2657      only used in a few files that include sockets-osdep.h
2658    
2659    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2660      does not process its return value since I don't know how to

2662    
2663    - It would probably be good to have a call to WSACleanup() when
2664      the library is unloaded (if there is such a possibility).
2665      Otherwise I think Windows will take care of this automatically
2666      when the process finishes.
2667    
2668    - I used ioctlsocket() as a replacement for ioctl() but I have
2669      no idea if that is actually the proper replacement on Windows.
2670    
2671    - All these issues are marked in the code by "FIXME" comments.

2673    We use sml/nj extensively in our products and are quite happy
2674    with it.  I hope this contribution will help you.

2713    The installer now honors the "src-smlnj" target again, although its meaning
2714    has changed from "all sources required for the compiler" to "all sources
2715    the installer knows about".  In other words, if you enable "src-smlnj"
2716    in the "targets" file, then the installer will pull in sources for
2717    everything.  (Notice that this refers to source code only.  Compiled
2718    code is still only installed for modules that were requested explicitly
2719    or which are required for other modules that were requested explicitly.)

2753    Description:
2754    
2755    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
2756    of SML/NJ.  The problem is that
2757    
2758       lib = dlopen(NULL, ...)
2759       f   = dlsym(lib, "malloc");
2760    
2761    does not work on Windows unless we explicitly export symbols
2762    such as 'malloc' during linking.  We fixed this by explicitly
2763    exporting the required symbols with the magic gcc incantation:
2764    
2765        -Wl,--export-all cygwin.def
2766    
2767    where cygwin.def is a file containing all the symbols that
2768    we wish to export.
2769    
2770    I suspect this is a Windows problem and we'll have to
2771    do the same (somehow with windows compilers) when
2772    we build the native win32 version with the system
2773    calls LoadLibrary/GetProcAddress.

2844    (The mechanism was broken and could not be fixed easily.  Moreover,
2845    there does not seem to be any reason not to move all libraries into
2846    lib during installation.  I originally implemented this directive as a
2847    backward-compatibility feature when I first introduced the new CM.
2848    Now that things have been stable for a long time and going back to the
2849    old CM is not an option, there is no reason to keep it around.)

2899    Description:
2900    
2901    I modified the read-eval-print loop so that the autoloader gets
2902    invoked whenever the prettyprinter tries to look up a symbol that
2903    is not currently defined in the toplevel environment but which
2904    appears in CM's autoload registry.  As a result, we see far fewer of
2905    those ?.Foo.Bar.xxx names in the prettyprinter's output.
2906    
2907    In addition to this I tried to clean up some pieces of the Basis
2908    implementation (e.g., Socket, Word8Array) in order to prevent other
2909    instances of these ?.Foo.Bar.xxx names from being printed.
2910    
2911    The mechanism that picks names for types still needs some work, though.
2912    (Right now it seems that if there is a type A.t which is defined to
2913    be B.u, but B is unavailable at toplevel, then A.t gets printed as
2914    "?.B.u" although the perhaps more sensible solution would be to use
2915    "A.t" in this case.  In other words, the prettyprinter should follow
2916    a chain of DEFtycs not farther than there are corresponding toplevel
2917    names in the current environment.)

2923    Description:
2924    
2925    Another installer tweak:  All the ML code for the installer is now
2926    compiled during CMB.make and put into a little library called
2927    $smlnj/installer.cm.  The installation then simply invokes
2928    
2929       sml -m $smlnj/installer.cm
2930    
2931    and everything happens automagically.
2932    
2933    Win32:  ML code senses value of environment variable SMLNJ_HOME.
2934    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
2935            and BINDIR.
2936    
2937    The new scheme guarantees that the ML code responsible for the installation
2938    is in sync with the APIs of the main system.  Also, the installer is
2939    somewhat faster because the installer script is precompiled.

2950    implementations of non-blocking operations from CML's Socket
2951    structure.

2956    Tag: blume-20030924-sockets
2957    Description:
2958    
2959    1. Fixed SOCKET API and implementation to match Basis spec.
2960       This required changing the internal representation of sockets to one
2961       that remembers (for each socket file descriptor) whether it is currently
2962       blocking or non-blocking.  This state is maintained lazily (i.e., a system
2963       call is made only if the state actually needs to change).
2964    
2965    2. OS-specific details of sockets were moved into separate files, thus
2966       making it possible to unify the bulk of the socket implementations
2967       between Unix and Win32.
2968    
2969    3. CML's socket API changed accordingly.
2970       (Note that we need to remove non-blocking functions from this API
2971       since they are redundant in the case of CML!)
2972    
2973    4. CML's socket implementation now makes use of non-blocking functions
2974       provided by Basis, thus removing all OS-dependent code from this part
2975       of CML.
2976    
2977    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

3092    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3093    Modified config/install.bat to take advantage of it.  Also modified
3094    config/install.sh (and called it config/new-install.sh) to take advantage
3095    of it on Unix systems.  (The SML code is (supposed to be) platform-
3096    independent.)
3097    
3098    The installer can now install everything under Win32
3099    as well as under *nix as long as it compiles.
3100    
3101    Other changes:
3102    
3103      - made CML compile again under Win32
3104      - made eXene compile under Win32 (by providing a fake structure UnixSock
3105        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3106      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3107        same as type int;  under Win32 it isn't
3108      - fixed some slice-related problems in the win32-specific parts of CML
3109      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3110        (under Win32, the volume name is case-insensitive, and the
3111        OS.Path code compares volume names for equality)

3117    Description:
3118    
3119    Made Win32 version of OS.FileSys.fullPath return current directory
3120    when given an empty string.  This is what the spec says, and incidentally,
3121    CM depends on it.  (CM otherwise goes into an infinite loop in certain
3122    cases when presented with the name of a non-existing .cm file.)

3128    Description:
3129    
3130      1. Changed interface to vectors and arrays in Basis to match
3131         (draft) Basis spec.
3132      2. Added signatures and implementations of slices according to
3133         Basis spec.
3134      3. Edited source code throughout the system to make it compile again
3135         under 1. and 2.  (In some cases code had to be added to have it
3136         match the new signatures.)
3137      4. MLRISC should be backward-compatible: the copies of the originals
3138         of files that needed to change under 3. were retained, the .cm files
3139         check the compiler version number and use old versions when
3140         appropriate.
3141      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3142         dirstream -> string option (in accordance with Basis spec).
3143      6. When generating code that counts lines, ml-lex used function
3144         CharVector.foldli, taking advantage of its old interface.
3145         This has been replaced with the corresponding code from
3146         CharVectorSlice.  (html-lex must be re-lexed!)
3147      7. BitArray in smlnj-lib/Util has been extended/modified to match the
3148         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
3149      8. Removed temporary additions (fromInternal, toInternal) from the
3150         (now obsolete) IntInf in smlnj-lib/Util.
3151      9. Cleaned up structure Byte.
3152     10. Added localOffset, scan, and fromString to Date (according to spec).
3153         Cleaned/corrected implementation of Date.
3154         (Still need to check for correctness; implement better canonicalizeDate.)
3155     11. Added "scan" to signature IEEE_REAL.
3156     12. Some improvements to IntInf [in particular: efficiency-hack for
3157         mod and rem when second operand is 2 (for parity checks).]
3158     13. Changed representation of type Time.time, using a single IntInf.int
3159         value counting microseconds.  This considerably simplified the
3160         implementation of structure Time.  We now support negative time
3161         values; scan and fromString handle signs.
3162     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3163         ArraySlice).

3169    Description:
3170    
3171    This is a major update which comes with a version number bump
3172    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3173    and an implementation of IntInf in the Basis.
3174    
3175    There are a fairly large number of related changes and updates throughout
3176    the system:
3177    
3178    Basis:
3179            - Implemented IntInf.
3180            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3181            - Added some missing Real64 operations, most notably Real.toLargeInt.
3182            - Added FixedInt as a synonym for Int32.
3183    
3184    compiler:
3185            * Added support for a built-in intinf type.
3186              - literals
3187              - pattern matching
3188              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3189              - overloading on literals and operations
3190    
3191            This required adding a primitive type intinf, some additional
3192            primops, and implementations for several non-trivial intinf
3193            operations in Core.  (The intinf type is completely abstract
3194            to the compiler; all operations get delegated back to the Core.)
3195    
3196            * Intinf equality is handled by polyequal.  However, the compiler
3197            does not print its usual warning in this case (since polyequal
3198            is the right thing to do there).
3199    
3200            * Improved the organization of structure InlineT.
3201    
3202            * A word about conversion primops:
3203            If conversions involving intinf do not cancel out during
3204            CPS contract, then the compiler must insert calls to Core functions.
3205            Since all core access must be resolved already during the FLINT
3206            translate phase, it would be too late a the time of CPS contract
3207            to add new Core calls.  For this reason, conversion primops
3208            for intinf carry two arguments:  1. the numeric argument that
3209            they are supposed to convert, and 2. the Core function that
3210            can help with this conversion if necessary.  If CPS contract
3211            eliminates a primop, then the associated Core function becomes
3212            dead and goes away.  Intinf conversion primops that do not get
3213            eliminated by CPS contract get rewritten into calls of their
3214            core functions by a separate, new phase.
3215    
3216    interactive system:
3217            - Control.Print.intinfDepth controls max length of intinf constants
3218            being printed. (Analogous to Control.Print.stringDepth.)
3219            - Cleanup in printutil and pputil: got rid of unused stuff and
3220            duplicates; replaced some of the code with code that makes better
3221            use of library functionality.
3222    
3223    CM:
3224            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3225            are no longer silent.
3226    
3227    CKIT:
3228            Fixed mismatched uses of Int32 and LargeInt.  I always decided
3229            in favor of LargeInt -- which is now the same as IntInf.
3230            CKIT-knowledgable people should check whether this is what's
3231            intended and otherwise change things back to using Int32 or
3232            FixedInt.
3233    
3234    Throughout the code:
3235            Started using IntInf.int literals and built-in operations
3236            (e.g., comparison with 0) where this seems appropriate.

3243    Description:
3244    
3245    Merging changes from the mcz-branch development branch into trunk.
3246    These changes involve replacement of the emulated old prettyprinter
3247    interface with direct use of the SML/NJ Lib PP library, and fixing
3248    of a couple of bugs (895, 1186) relating to error messages.  A new
3249    prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
3250    has been added.

3256    Description:
3257    
3258    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
3259    
3260        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3261    
3262    This patch restores SML/NJ's ability to run under win32.  There are a
3263    number of changes, including fixes for several bugs that had gone
3264    unnoticed until now:
3265    
3266      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3267        trying to run the win32 version from within cygwin.)
3268    
3269      - There are a number of simple .bat scripts that substitute for their
3270        corresponding Unix shell-scripts.  (See below.)
3271    
3272      - The internals of ml-build have been modified slightly.  The main
3273        difference is that instead of calling ".link-sml" (or link-sml.bat)
3274        using OS.Process.system, the ML process delegates this task back
3275        to the script.  Otherwise problems arise in mixed environments such
3276        as Cygwin where scripts look and work like Unix scripts, but
3277        where OS.Process.system cannot run them.
3278    
3279      - In CM, the srcpath pickler used native pathname syntax -- which
3280        is incorrect in the case of cross-compilation.  The new pickle format
3281        is independent of platform-specific naming conventions.
3282    
3283      - Path configuration files (such as lib/pathconfig) can now choose
3284        between native and standard syntax.  Placing a line of the form
3285    
3286            standard!
3287    
3288        into the file causes all subsequent paths to be interpreted using
3289        CM standard pathname syntax (= Unix conventions); a line
3290    
3291            native!
3292    
3293        switches back to native style.  This was needed so that
3294        path config files can be written portably, see src/system/pathconfig.
3295    
3296      - Runtime system:
3297    
3298          - win32-filesys.c:  get_file_time and set_file_time now
3299            access modification time, not creation time.
3300    
3301          - I/O code made aware of new array representation.
3302    
3303          - Bug fixes in X86.prim.masm.
3304    
3305       - src/system/makeml made aware of win32. (For use under cygwin
3306            and other Unix-environments for windows.)
3307    
3308       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3309         which caused BinIO.inputAll to fail consistently.
3310    
3311    .bat scripts:
3312    
3313       Windows .bat scripts assume that SMLNJ_HOME is defined.
3314    
3315       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
3316         applications (sml, ml-yacc, ml-lex).
3317       - ml-build.bat: analogous to ml-build.
3318       - config\install.bat:  Analogous to config/install.sh.  This requires
3319         that SMLNJ_HOME is set and that Microsoft Visual C is ready
