87    
88    - Aaron: fixed a number of bugs in ml-ulex.
89    - Matthias:
90       - added CM control "cm.force-tools"; this is false by default;
91         when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
92         will be forced to run regardless of whether or not their targets
93         are up-to-date
94       - changed installer code so that config/install.sh will re-build
95         heap images for all tools even if those heap images already existed

102    After Aaron Turon's bug fix for ml-ulex (handling the ^ character
103    in legacy mode), re-ran the lexer generator on all lex input files
104    and committed the results.
105    
106    This should fix the problem with ckit and nlffi that was reported

122    
123    3rd merge of base from primop-branch-3 into the trunk.
124    Additional bug fixes included:
125    
126     * Timer.cpu_timer, etc. type printing corrected (by making
127         Timer have opaque sig constraint in basis/Implementation/timer.sml)
128     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by

133    Date: 2007/05/31 11:40:00 CDT
134    Description:
135    
136    Fixed some bugs in new Div code in FLINT/trans/translate.sml.
137    
138    Also, changed the handling of "no core access":  When translate.sml
139    needs access to a core exception at a time when the core has not
140    been set up yet (this only happens when compiling system/smlnj/init/*),
141    then don't bother generating the corresponding tests.
142    
143    The old scheme was to generate a bogus value to be used in place of
144    the exception.  Unfortunately, that confuses the plambda type checker.
145    Moreover, it does not do any good, because at runtime we don't expect
146    such an exception to be ever raised.  (The code in system/smlnj/init/*
147    has to be written very carefully with this in mind!)

159    Description:
160    
161    FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
162    with an explicit test for zero division.  This should fixes several
163    regressions and makes it possible for downstream optimization phases
164    to treat these operations as "pure" when they are applied to unsigned
165    operands.

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

180    
181    A number of fixes related to the formatting of dates.  These include fixes
182    for bugs #1415 and #1416.  We also now correctly handle format characters that
183    lie outside the specified set.

187    Date: 2007/05/23 22:30:00 CDT
188    Description:
189    
190    CMB (and CM) now automatically defines the CM "preprocessor" symbol
191    NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
192    
193      (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
194       CM_SLAVE_MODE is defined in attached slaves while running CM.make
195       or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
196       while running CMB.make.  The point is that the single symbol
197       NO_PLUGINS is definde in all three cases.)
198    
199    I changed the three locations within the sources that get compiled
200    during CMB.make where ml-yacc or ml-lex input is processed: When
201    NO_PLUGINS defined, then the use of the mlyacc and mllex tools
202    is bypassed.
203    
204    When bootstrapping new versions of the compiler, there can be
205    situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
206    are not available or otherwise not operational.  In this case one can
207    manually define the NO_PLUGINS symbol prior to running CMB.make().  To
208    do so, the following command should be issued at the interactive
209    prompt:
210    
211       #set (CMB.symval "NO_PLUGINS") (SOME 1);
212    
213    A CMB.make with NO_PLUGINS defined relies on the existence of the
214    files that normally would be generated by ml-yacc and ml-lex.
215    (Copies of these files are in the repository.)

223    2nd merge of base from primop-branch-3 into the trunk.

231    Description:
232    
233    Changed the installation mechanism for CM tool plugins.  These are
234    just libaries and now get installed like ordinary libaries.
235    
236    There are now a number of new installation targets that give some
237    fine-grain control over what classes and suffixes are known, and what
238    they will map to.
239    See config/targets for details.
240    
241    The code that caused plugin installation as part of running a
242    tool's "build" script has been removed.  (The build script is for
243    building, not for installing.)

248    Description:
249    
250    Added a boolean control named cm.tolerate-tool-failures (env. variable
251    name: CM_TOLERATE_TOOL_FAILURES).  The default is false and makes
252    CM fail if a shell tool reports a non-success exit status.  If
253    the control is set to true, then CM will press on after tool failures
254    in the event that the target files exist (even though they are
255    considered outdated).  Turning the control to true can be useful for
256    bootstrapping.

261    Description:
262    
263    Merge of ml-lpt revisions for 110.64.
264    
265    The name of several ml-lpt-lib modules has changed:
266      Repair        => AntlrRepair
267      StreamPos     => AntlrStreamPos
268      ErrHandlerFn  => AntlrErrHandler
269      EBNF          => AntlrEBNF
270    
271    The ml-antlr specification format has changed: declarations such as
272    %tokens and nonterminal definitions can occur *multiple* times in the
273    same specification.  The semantics are such that each new declaration
274    extends the previous ones.  This does not apply to %start or %name,
275    of course.
276    
277    Importing a grammar via %import now includes *all* declarations in from
278    the imported grammar, except for %name, %entry, and %start.  Tokens
279    and nonterminals can be dropped using the new %dropping clause of the
280    %import directive; the separate %drop and %extend have been removed.
281    
282    We now allow optional type annotations on nonterminals, using the %nonterms
283    directive as in ml-yacc.
284    
285    The refcell construct is now implemented using SML's regular reference
286    cells, so the :== and !! notation has been deprecated.
287    
288    The ml-antlr tool now does much more checking of specifications, and
289    its error messages have been greatly improved.  Error repair for
290    generated parsers has been completely rewritten, and is now both
291    much faster and more accurate.
292    
293    ml-ulex is now more lenient with escape codes (non-SML-standard
294    escape codes are now interpreted literally, so e.g. \| denotes "|").
295    Also, character classes may now include a "-" character at the beginning
296    as is standard in most other regexp tools.
297    
298    All of these changes are documented in the user guide, which has
299    been updated and improved with this merge.

452    Added preliminary support in MLRISC for Staged Allocation, a technique
453    for specifying calling conventions (see

457    The staged allocation code base resides in MLRISC/staged-allocation,

467      promoted to tagless pair.

524    
525    Brought ml-lpt manual up-to-date with the code.  Many minor
526    improvements to the tools, and a few minor bugfixes.  Prepared
527    ml-lpt-lib for integration with new UTF8 structure.  Changed
528    the interface for creating streams in ml-ulex (we now support
529    stream creation from several kinds of sources).  Overall, the
530    tools are now quite stable, and their interfaces are unlikely to
531    change in a way that would break compatibility.  More work,
532    however, is needed in the documentation.

537    Description:
538    
539    Implemented library installer.  Moved CM plugin code for
540    ml-burg, ml-lex, and ml-yacc out of CM source tree and into
541    their respective trees.  Implemented CM plugin for ml-ulex
542    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
543    and ml-antlr.
544    
545    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
546    CM tools.  (It turns out to be too messy to do otherwise because
547    there is too much code that during installation relies on the presence
548    of these tools -- resulting in a tricky ordering problem.)

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

628    Description:
629    
630    Added code to CM's "standard shell tool" implementation which
631    causes it to tolerate (with a warning) the situation where the shell
632    command fails (e.g., due to the shell command's non-existence)
633    as long as all target files exist.
634    
635    This makes it possible to, e.g., build ml-yacc from sources even if
636    svn checkout messed up the time stamps on files in such a way that
637    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
638    be needed to re-process yacc.grm, but obviously it might not yet be
639    available at that time.)

679    Description:
680    
681    New working release (110.60).  NEW BOOTFILES!
682    
683    This is the first subversion-hosted release.  There are also changes
684    to the directory layout.  Here is a table:
685    
686    (All pathnames are relative to the SML/NJ "root" directory.)
687    
688      config -> config
689    
690      src/cm -> base/cm
691      src/compiler -> base/compiler
692      src/runtime -> base/runtime
693      src/system -> base/system
694    
695      src/cm/pgraph -> pgraph
696    
697      src/READMES -> base/READMES
698      src/$notefile -> base/NOTES/$notefile
699         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
700                           MACOSXINSTALL WININSTALL
701    
702      src/smlnj-lib -> smlnj-lib
703      src/MLRISC -> MLRISC
704      ckit -> ckit
705      src/cml -> cml
706      src/eXene -> eXene
707      src/heap2asm -> heap2asm
708      src/lexgen -> lexgen
709      src/ml-burg -> ml-burg
710      src/ml-lex -> ml-lex
711      src/ml-yacc -> ml-yacc
712      src/ml-nlffi-lib -> nlffi/lib
713      src/ml-nlffigen -> nlffi/gen
714      src/smlnj-c -> smlnj-c
715      src/tools/TraceDebugProf -> trace-debug-profile
716    
717    In addition, there is also a new
718    
719      ml-lpt
720    
721    directory containing two new program generator tools: ml-ulex and
722    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
723    LL(k) parser generator). These tools are currently "beta-quality"
724    
725    The latest versios of the sources can now be obtained anonymously
726    via subversion.  For this, it is useful to first check out
727    
728       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
729    
730    and put the resulting directory on your shell's PATH.  This provides
731    access to three shell scripts: checkout-all.sh, stat-all.sh,
732    and refresh-all.sh.
733    
734    To create a freshly checked-out copy of the sources, do
735    
736       checkout-all.sh [dir]
737    
738    where dir is the optional SML/NJ root directory (default is ".").
739    
740    This creates the above directory layout.  Each subdirectory of
741    the root is under individual subversion control.  The stat-all.sh
742    and refresh-al.sh scripts apply "svn stat" or "svn update" to
743    each of these subtrees.
744

746    Name: Matthias Blume (http://www.tti-c.org/blume/)
747    Date: 2006/11/02 12:20:00 CST
748    Description:
749    
750    Reorganized directory layout.
751    
752    This is a temporary solution, more reorganization is to come.
753    
754    The basic idea is to have a number of toplevel trees, each corresponding
755    to a well-defined part of the overall system.  Each part can be
756    maintained individually, even in separate source repositories,
757    although currently we still serve everything out of the main
758    smlnj-gforge tree.
759    
760    Installer and and scripts have been updated to reflect the new
761    layout.  The installer (base/src/system/smlnj/installer) is now
762    "scriptable" to avoid burning too much knowledge about the
763    layout into SML source code.  The main script used by the installer
764    is in config/actions.
765    
766    The main change is that many of the subdirectories of what used to
767    be known as "src" have moved to the toplevel.  The "src" directory
768    itself has moved down into a subtree called "base".  (We may eventually
769    get rid of the extra level of indirection represented by "src".)
770    
771    The layout is now as follows:
772    
773      toplevel tree name | default repository
774                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
775      -------------------+----------------------------------------------------
776      config             | $gf/config/trunk
777                         |
778      base               | $gf/sml/trunk
779                         |
780      smlnj-lib          | $gf/smlnj-lib/trunk
781      MLRISC             | $gf/MLRISC/trunk
782                         |
783      ml-yacc            | $gf/ml-yacc/trunk
784      ml-lex             | $gf/ml-lex/trunk
785      ml-burg            | $gf/ml-burg/trunk
786      lexgen             | $gf/lexgen/trunk
787      heap2asm           | $gf/heap2asm/trunk
788                         |
789      cml                | $gf/cml/trunk
790      eXene              | $gf/eXene/trunk
791      ckit               | $gf/ckit/trunk
792      nlffi              | $gf/nlffi/trunk
793                         |
794      smlnj-c            | $gf/smlnj-c/trunk
795    
796    In $gf/admin there are a few useful shell scripts for checking out
797    and maintaining the entire collection of trees:
798    
799       admin/checkout-all.sh [dir]
800          -- optionally creates dir and checks out all trees from their
801             default repositories; if dir is missing, checkout into .
802       admin/refresh-all.sh [dir]
803          -- looks at all trees (from the above list) in dir (default: .)
804             and runs "svn update" if the tree exists and is under
805             subversion control;
806             non-existing or non-subversion trees are skipped
807       admin/stat-all.sh [dir]
808          -- like refresh-all.sh, but runs "svn stat" instead

832             "fixed bugs in X authorization and resource handling, as well
833              as in the pile and viewport widgets"
834    
835      Runtime:
836        * fixed linking problem with NetBSD 3.x.
837    
838      Lexgen:
839        * lexgen tool handles non-ascii characters in 7-bit mode the same
840          way that ml-lex does
841    
842        * lexgen propagates exceptions the same way that ml-lex does
843    
844      CML:
845        * Fixed a bug in the SyncVar polling functions (iGetPoll,
846          mTakePoll, and mGetPoll) that could lead to livelock.

954    Description:
955    
956    Hooked code for Darwin-specific Intel ABI into main compiler.
957    (This is a temporary solution which relies on the fact that the
958    compiler itself does not use NLFFI.  Eventually we need to divorce
959    intel mac from generic x86 unix code and make separate sets of binaries.)

988    Description:
989    
990    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
991    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
992    at the time when config/preloads is processed, the library has to
993    be referred to by another name.  In 110.57 this would be
994    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
995    to be valid as well.)

1050    Tag: blume-22051115-versiontool
1051    Description:
1052    
1053    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
1054    file gets loaded as a tool -- by the equivalent of CM.make during the
1055    run of CMB.make.  Thus, CMB's path configuration is meaningless for
1056    it.  Instead, it has the status of "user code", so it should use
1057    $/basis.cm to refer to the Basis library.  (At least that's true for
1058    the purpose of bootstrapping the previous change.  In the future it
1059    might make sense to have versiontool.cm refer to
1060    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1061    compiler itself uses.)
1062    
1063    Also patched src/system/testml to have it activate those extra anchor
1064    bindings in config/extrapathconfig.

1069    Tag: blume-22051115-libraries
1070    Description:
1071    
1072    This change affects the way the following libraries are tied into
1073    the system:
1074    
1075       $/basis.cm
1076       $/smlnj-lib.cm
1077       $/pp-lib.cm
1078       $/controls-lib.cm
1079       $/html-lib.cm
1080       $/ml-yacc-lib.cm
1081    
1082    These libraries are now internally (as seen from the source code
1083    of the implementation itself) known by the following names:
1084    
1085       $smlnj/basis/basis.cm
1086       $smlnj/smlnj-lib/smlnj-lib.cm
1087       $smlnj/smlnj-lib/pp-lib.cm
1088       $smlnj/smlnj-lib/controls-lib.cm
1089       $smlnj/smlnj-lib/html-lib.cm
1090       $smlnj/ml-yacc/ml-yacc-lib.cm
1091    
1092    This makes it possible to work with code that requires different
1093    versions of these libraries, and which refers to these libraries using
1094    their "default" names (i.e., the first set of names above).  In other
1095    words, one can un-define or re-define those default names without
1096    compromising the proper functioning of the compiler itself.
1097    
1098    A similar procedure had already been performed for several of the
1099    MLRISC libraries that are linked into the compiler.  I did some
1100    cleanup on this code.
1101    
1102    A new file in the config directory (named extrapathconfig) is
1103    responsible for setting up path anchors that the compiler itself does
1104    not need, but that are typically required by user code.

1284    Description:
1285    
1286    Added mechanism for re-creating a heap file for the interactive system
1287    after configuration variables have been changed.
1288    
1289       CM.redump_heap : string -> unit
1290    
1291    This is much like SMLofNJ.exportML, but starting from the resulting
1292    heap does not return to the caller of CM.redump_heap but
1293    restarts the interactive system from scratch.  The original call of
1294    CM.redump_heap does not return but ends the interactive session.
1295    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1296    
1297    Internally, redump_heap winds the dynamic execution context back to
1298    the point where the original heap image was created and re-executes
1299    the heap image generation code in the boot code.

1415    Tag: blume-20050114-heap2exec
1416    Description:
1417    
1418    Implemented new (but still experimental) heap2exec facility.  This is
1419    tested under Mac OS X and should work under Linux (will test shortly).
1420    It will probably also work on the Sparc (will test some time later).
1421    
1422      - removed old "HACKED_STANDALONE" hack from runtime
1423    
1424    To be able to test this, uncomment the request for "heap2asm" in
1425    config/targets prior to installation.  (Notice that this is different
1426    from "heap2exec" mentioned below.  Not a typo.)
1427    
1428    To perform an actual test, run the command
1429    
1430       $ bin/heap2exec heapfile execfile
1431    
1432    (You can put heap2exec on your shell's path.)
1433    
1434    For example, run
1435    
1436      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1437    
1438    This will create a standalone executable called "mly" which you can
1439    then invoke directly as a command.

1584    Tag: blume-20041124-position
1585    Description:
1586    
1587    The compiler can now be compiled in a mode that makes structure Position
1588    equal to Int64.  The default, however, is unchanged (Position = Int31)
1589    for the time being.
1590    
1591    To enable 64-bit positions, use the following procedure:
1592    
1593    1. Start sml
1594    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1595    3. Type
1596          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1597    4. Run CMB.make() as usual.
1598    
1599    This is barely tested.  The only test so far was a little SML program
1600    counting the number of characters in an 8-gigabyte file by
1601    reading it character-by-character.  That test was successful.
1602    
1603    In support of 64-bit positions, a number of new functions have been
1604    added to the runtime system.

1649    
1650    - In a previous commit, fixed a minor issue with how polyequal is being
1651      translated.  In particular, the code now "looks through" abstractions.
1652      This results in slightly fewer polyEqual warnings and hopefully slightly
1653      more efficient code.  Important examples for where this matters are
1654      the new int64 and word64 types.

1674    32-bit wide.)
1675

1677    are still missing.

1683    Description:
1684    
1685    Structure Word64 is now (almost) complete, word literals and patterns
1686    seem to work.  There are a few odd pieces missing.  In particular,
1687    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1688    at the moment.
1689    
1690    Making Word64 official would mean that LargeWord becomes Word64.  But
1691    this requires extreme care because most word-word conversions have to
1692    go through LargeWord, so making a mistake means loss of efficiency or
1693    worse.  Eventually there will be a solution similar to (but actually
1694    simpler than) what I did with IntInf.

1730      - Default contents of config/srcarchiveurl uses $VERSION and
1731        normally does not have to be edited to reflect a version change.
1732    
1733      (As a result, a version change can be done by just editing
1734       config/version, the rest is now automatic.)

1774    Tag: blume-20041020-standalone-backtrace
1775    Description:
1776    
1777    Added a mechanism for getting back-trace information from standalone
1778    programs.  Here is how it works:
1779    
1780       1. The part of the program from which you want to get backtrace
1781          information (usually the whole program) should be wrapped with
1782          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
1783          main program could be modified from something like
1784    
1785             fun main (pgm, args) = ...
1786    
1787         to
1788    
1789            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1790    
1791       2. To be able to access BackTrace.monitor, you have to add
1792          library $smlnj-tdp/plugins.cm to the .cm file that contains your
1793          main function.
1794    
1795       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1796          CM might have created in the past for your project).
1797    
1798       4. Build the system using this command line:

1808    
1809       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1810    
1811    New libraries:
1812    
1813       $smlnj-tdp/back-trace.cm
1814          -- when loaded causes the back-trace plugin to be installed
1815       $smlnj-tdp/coverage.cm

1832    Description:
1833    
1834    * Test coverage tool added!
1835    * Further reorganization of tracing-, debugging-, and profiling support:
1836    
1837        - moved original BTImp -- now called BackTrace -- into a separate
1838          library called $/trace-debug-profile.cm
1839        - eliminated all mentions of BTrace from SMLofNJ.Internals
1840        - only the instrumentation mechanism is now left in the compiler proper
1841        - BackTrace module is a plugin which is NOT plugged in by default
1842        - Coverage module is another such plugin
1843    
1844    To get the benefits of any of these plugin modules, the code in
1845    question must be compiled with tdp instrumentation turned on.  This
1846    can be done by setting SMLofNJ.Internals.TDP.mode to true.
1847    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1848    
1849    Plugins are selected at link time.  (Pre-compiled instrumented code
1850    can be re-loaded with different plugins in effect.)  When an
1851    instrumented module is linked, whatever plugins are at that time
1852    enabled will come into effect for that module.
1853    
1854    To enable the back-trace plugin, load library $/trace-debug-profile.cm
1855    and invoke BackTrace.install() (e.g., from the interactive prompt).
1856    To enable the coverage plugin, load the same library and invoke
1857    Coverage.install().
1858    
1859    Back-traces are generated automatically on uncaught exceptions and
1860    when the code in question explicitly invokes BackTrace.trigger().
1861    
1862    Coverage (and execution frequency-) information must be queried
1863    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

1880    Some rationalization of names:

1883       etc.
1884    
1885    This is is preparation of using the original back-trace
1886    instrumentation for other purposes.  "TDP" stands for
1887    Trace/Debug/Profile.
1888    
1889    The control flag controlling whether instrumentation is on or off is now
1890    registered under a different name, so instead of running sml as
1891    
1892     sml -Cinstrument.btrace-mode=true
1893    
1894    one has to say
1895    
1896     sml -Ctdp.instrument=true

1912    Description:
1913

1915    treats subsequent occurrences of "group", "library", "source", "is",
1916    "*", and "-" as ordinary identifiers rather than keywords.
1917    
1918    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
1919    is supposed to accept a tool argument called "source", but this did
1920    not work because of the clash with the keyword.

1963    Description:
1964    
1965    * Moved the "version" magic into its own little library under
1966      src/system/smlnj/internal.  This avoids expensive reconstruction of
1967      a stable src/compiler/core.cm.
1968    
1969    * At the same time, structure CompilerVersion is now known as
1970      structure SMLNJVersion.
1971    
1972    * Arranged for the version tool to NOT kick in when rebuilding the system
1973      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
1974      Also, loading the versiontool does not work when rebuilding the system
1975      because CM is not properly initialized at that time.

1980    Tag: blume-20040929-autoversion
1981    Description:
1982    
1983    Implemented some CM magic to have
1984        file src/compiler/TopLevel/main/version.sml
1985    generated automagically.
1986    The version is taken from two files: config/version and config/release.
1987    The first is expected to contain a two-part version number such as 110.49.
1988    The second should contain a single number, but it may be missing.
1989    
1990    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
1991    time the version tool is loaded (which is the first time you say CMB.make),
1992    then the tool will increment the value stored in config/release every
1993    time CMB.make is invoked.
1994    
1995    The binfile format is now insensitive to anything beyond the first
1996    two components of a version number, so bumping the release does not render
1997    binfiles incompatible.  Auto-bumping can be used to keep track of versions
1998    during development without invalidating existing binfiles.
1999    
2000    In any case, every CMB.make updates the date information in version.sml.
2001    (This is the date that is printed in the banner.)

2014    Tag: blume-20040927-controls
2015    Description:
2016    
2017    Added two pieces of functionality to the Controls interface:
2018    
2019    1.   val save'restore: 'a control -> unit -> unit
2020    
2021       grabs the current value of the control in stage 1 and restores it
2022       in stage 2.
2023    
2024    2.   val set' : 'a control * 'a -> unit -> unit
2025    
2026       stores the given value into the control in stage 2 (i.e., delayed)
2027       but does all error checking in stage 1.
2028       (This is for string controls that need to do parse their argument --
2029        something that might fail.  In some cases, notably in CM, one
2030        already knows the intended argument but wants to delay the actual
2031        assignment until a time when error recovery would be more difficult.)
2032    
2033    Changed the handling of controls in tool arguments to classes "sml" and
2034    "lazysml":
2035       - use Controls.save'restore as a more robust way of restoring the
2036         old value (in particular: without having to re-parse the string)
2037       - use controls to handle the "overload" keyword in the init group
2038         (I believe this change actually fixes a long-standing obscure bug.)

2043    Tag: blume-20040927-lazysml
2044    Description:
2045    
2046    Added a new tool class called "lazysml" to CM's tool chest.  The only
2047    difference to "sml" is that compilation is done with Control.lazysml
2048    set to true.  A source of class "lazysml" is automatically recognized
2049    by a file name suffix of ".lml".
2050    
2051    In addition to the above feature, the original class "sml" now also
2052    supports a tool argument "lazy" which has the same effect.  As a
2053    result, the following three lines are equivalent:
2054    
2055        foo.sml : lazysml
2056        foo.sml : sml (lazy)
2057        foo.sml (lazy)
2058    
2059    The setting goes into effect both during parsing and during
2060    compilation.  The original setting is restored right after parsing and
2061    after compilation, respectively.
2062    
2063    In addition to all the above, there is also a general mechanism to set
2064    ANY of the "controls" that are available at the command line via
2065    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
2066    apply as well. (In fact, "lazy" is implemented as a special case of
2067    the general mechanism.)
2068    
2069    The .cm file syntax uses a new keyword tool argument called "with".
2070    There are several ways of indicating the desired settings:
2071    
2072        foo.sml (with:parser.quotations=true)
2073        foo.sml (with:(name:parser.quotations value:true))
2074        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2075        foo.sml (with:(name1=value1 name2=value2 ...))
2076        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2077    
2078        etc.
2079    
2080    Another possible abbreviation is to leave out the =v or value:v part
2081    if the name refers to a boolean control (in which case the value is
2082    taken to be true).  Thus, one could get lazy sml also by saying:
2083    
2084        foo.sml (with:parser.lazy-keyword=true)
2085        foo.sml (with:parser.lazy-keyword)
2086        foo.sml (with:(name:parser.lazy-keyword value:true))
2087        foo.sml (with:(name:parser.lazy-keyword))

2234    Description:
2235    
2236    Bug fix from Carl Hauser:
2237    
2238    single_source_shortest_paths in dijkstra.sml was observed to get wrong
2239    answers (by comparing to single_source_shortest_paths in bellman-ford.sml).
2240    
2241    The problem is that following the expression A.update(dist,s,Num.zero)
2242    it is necessary to update the priority queue using Q.decreaseWeight(Q,s).

2250    Fiddled with handling of command-line options:
2251    
2252      * sml now quits after processing the command line
2253        if -H, -S, -h<n>, or -s<n> appears as the last
2254        command-line argument
2255      * a new option -q terminates the session when encountered on
2256        the command line; subsequent arguments will be ignored
2257      * bug fixes: short (erroneous) arguments are no longer ignored
2258        completely

2316    
2317    - various minor bugfixes to ml-nlffigen
2318    - a beginning of a manual for nlffi
2319    
2320    - eliminated 'export name=value' in config/install.sh as this does

2386    - use paramAlloc to report c-calls with too many arguments
2387      (for PPC version where parameter area is pre-allocated)
2388    - added ccall_maxargspace to machspec (to implement the above)
2389    - made "make" commend in CM's "make" tool configurable
2390    - added option (default: on) for passing the name of the SML/NJ's "bin"
2391      directory to "make"; the call looks like this:
2392    
2393         make <options> SMLNJ_BINDIR=<dir> <target>
2394    
2395      This can be used by the Makefile to, e.g., pick the "right" version

2407    
2408    Note:  1. You have to make a new, clean build of the runtime system.
2409           2. There are new BOOTFILES, you have to use them!
2410              (Doing the bootstrap process yourself would be *very* painful!
2411               If you absolutely have to do it, build the system under
2412               a different architecture and then cross-compile.)
2413    
2414    Version bumped to 110.46.1 to account for runtime data format changes.

2439    Description:
2440    
2441    Changed the interface of structures Timer and Unix to match the most
2442    recent Basis spec.
2443    
2444    In the case of Unix there still seems to be an open/weird issue:
2445    
2446       The {text,bin}{In,Out}streamOf functions are supposed to create
2447       fresh streams whenever they are called -- as opposed to have them
2448       return the same stream every time.  This design is supposed to
2449       prevent space leaks caused by proc values hanging on to streams.
2450    
2451       The reap function, on the other hand, is supposed to close the
2452       streams.  This cannot be done without having a handle on the
2453       stream in proc after all...
2454    
2455    I took the liberty to implement the following stopgap solution:
2456    
2457      The proc value hangs on to the most recently created stream(s).
2458      Reap closes those.  If either or both of the two streams hadn't
2459      been created at all yet, then reap will close the corresponding
2460      file descriptors directly.
2461    
2462    PS: I don't understand the original space leak argument anymore.  If
2463    a proc hangs on to the imperative stream, then I/O operations on those
2464    will advance the state of the cached stream and avoid the space leak.

2478    Description:
2479    
2480    CM now ignores (but still accepts) the "owner" information in group
2481    descriptions.  The owner of a group is its next enclosing
2482    library. Each group must have a unique owner.  (There is a virtual
2483    "toplevel" library that owns groups which are not nested within a real
2484    library.)  Previously, each group had to explicitly declare its owner,
2485    and CM would check that such a declaration is correct.  The new scheme
2486    is to have CM check that for each group there is precisely one owning
2487    library.
2488    
2489    The advantage of the new scheme is that the programmer no longer needs
2490    to maintain the somewhat annoying owner information.  The downside is
2491    that CM cannot enforce the ownership rule across multiple runs of
2492    CM.make.  Fortunately, enclosing the same group in two different
2493    libraries A and B which are not part of the same program does not
2494    cause real problems.

2513    Description:
2514    
2515    Arranged for ml-build to clean up after itself a little bit better.
2516    The script generates a temporary SML source file and compiles it using
2517    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
2518    gets rid of those at the end, so they don't accumulate under .cm.
2519    
2520    This required a minor change to install.sh because the name of the
2521    metadata directory (default: .cm) is actually configurable at
2522    installation time.

2538    
2539    Added previously missing support for many socket-related functions
2540    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
2541    for the voluminous patch!
2542    
2543    (I have not tested this patch under win32 yet.)
2544    
2545    Here is David's e-mail:
2546    
2547    Hi,
2548    
2549    Attached to this email you find a diff against sml/nj 110.45
2550    that will enable socket support under Windows.
2551    
2552    To apply the patch (using unix or cygwin)
2553    1) gunzip runtime.diff.gz
2554    2) "cd" into "src/runtime" in the source tree of a fresh
2555       110.45 installation.
2556    3) patch -p 1 < [your/path/to]runtime.diff
2557    
2558    The code compiles fine but has NOT yet been extensively tested.
2559    I only ran a few tests for basic socket client functionality
2560    (which worked fine).  Especially the functions that use ioctl
2561    are not tested at all and might not work (see below).
2562    
2563    I implemented this since we want to move to a newer version of sml/nj
2564    but need socket support in order to use it.  This is the first time I
2565    even had a look at the sml/nj source,  so please review my changes
2566    before making this part of the distribution!  Here are a few issues
2567    that I think might be better for someone to solve who is more
2568    familiar with the sml/nj source (and socket programming):
2569    
2570    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2571      exception since I could not figure out what the windows equivalent
2572      of these functions is
2573    
2574    - In sockets-osdep.h there are a some #include statements that are
2575      only used in a few files that include sockets-osdep.h
2576    
2577    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2578      does not process its return value since I don't know how to
2579      report an error upwards.
2580    
2581    - It would probably be good to have a call to WSACleanup() when
2582      the library is unloaded (if there is such a possibility).
2583      Otherwise I think Windows will take care of this automatically
2584      when the process finishes.
2585    
2586    - I used ioctlsocket() as a replacement for ioctl() but I have
2587      no idea if that is actually the proper replacement on Windows.
2588    
2589    - All these issues are marked in the code by "FIXME" comments.
2590    
2591    We use sml/nj extensively in our products and are quite happy
2592    with it.  I hope this contribution will help you.
2593    
2594    Keep up the good work!
2595

2634    in the "targets" file, then the installer will pull in sources for
2635    everything.  (Notice that this refers to source code only.  Compiled
2636    code is still only installed for modules that were requested explicitly
2637    or which are required for other modules that were requested explicitly.)

2671    Description:
2672    
2673    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
2674    of SML/NJ.  The problem is that
2675    
2676       lib = dlopen(NULL, ...)
2677       f   = dlsym(lib, "malloc");
2678    
2679    does not work on Windows unless we explicitly export symbols
2680    such as 'malloc' during linking.  We fixed this by explicitly
2681    exporting the required symbols with the magic gcc incantation:
2682    
2683        -Wl,--export-all cygwin.def
2684    
2685    where cygwin.def is a file containing all the symbols that
2686    we wish to export.
2687    
2688    I suspect this is a Windows problem and we'll have to
2689    do the same (somehow with windows compilers) when
2690    we build the native win32 version with the system
2691    calls LoadLibrary/GetProcAddress.

2762    (The mechanism was broken and could not be fixed easily.  Moreover,
2763    there does not seem to be any reason not to move all libraries into
2764    lib during installation.  I originally implemented this directive as a
2765    backward-compatibility feature when I first introduced the new CM.
2766    Now that things have been stable for a long time and going back to the
2767    old CM is not an option, there is no reason to keep it around.)

2816    Tag: blume-20030926-ppautoload
2817    Description:
2818    
2819    I modified the read-eval-print loop so that the autoloader gets
2820    invoked whenever the prettyprinter tries to look up a symbol that
2821    is not currently defined in the toplevel environment but which
2822    appears in CM's autoload registry.  As a result, we see far fewer of
2823    those ?.Foo.Bar.xxx names in the prettyprinter's output.
2824    
2825    In addition to this I tried to clean up some pieces of the Basis
2826    implementation (e.g., Socket, Word8Array) in order to prevent other
2827    instances of these ?.Foo.Bar.xxx names from being printed.
2828    
2829    The mechanism that picks names for types still needs some work, though.
2830    (Right now it seems that if there is a type A.t which is defined to
2831    be B.u, but B is unavailable at toplevel, then A.t gets printed as
2832    "?.B.u" although the perhaps more sensible solution would be to use
2833    "A.t" in this case.  In other words, the prettyprinter should follow
2834    a chain of DEFtycs not farther than there are corresponding toplevel
2835    names in the current environment.)

2841    Description:
2842    
2843    Another installer tweak:  All the ML code for the installer is now
2844    compiled during CMB.make and put into a little library called
2845    $smlnj/installer.cm.  The installation then simply invokes
2846    
2847       sml -m $smlnj/installer.cm
2848    
2849    and everything happens automagically.
2850    
2851    Win32:  ML code senses value of environment variable SMLNJ_HOME.
2852    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
2853            and BINDIR.
2854    
2855    The new scheme guarantees that the ML code responsible for the installation
2856    is in sync with the APIs of the main system.  Also, the installer is
2857    somewhat faster because the installer script is precompiled.

2868    implementations of non-blocking operations from CML's Socket
2869    structure.

2874    Tag: blume-20030924-sockets
2875    Description:
2876    
2877    1. Fixed SOCKET API and implementation to match Basis spec.
2878       This required changing the internal representation of sockets to one
2879       that remembers (for each socket file descriptor) whether it is currently
2880       blocking or non-blocking.  This state is maintained lazily (i.e., a system
2881       call is made only if the state actually needs to change).
2882    
2883    2. OS-specific details of sockets were moved into separate files, thus
2884       making it possible to unify the bulk of the socket implementations
2885       between Unix and Win32.
2886    
2887    3. CML's socket API changed accordingly.
2888       (Note that we need to remove non-blocking functions from this API
2889       since they are redundant in the case of CML!)
2890    
2891    4. CML's socket implementation now makes use of non-blocking functions
2892       provided by Basis, thus removing all OS-dependent code from this part
2893       of CML.
2894    
2895    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

3008    Description:
3009    
3010    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3011    Modified config/install.bat to take advantage of it.  Also modified
3012    config/install.sh (and called it config/new-install.sh) to take advantage
3013    of it on Unix systems.  (The SML code is (supposed to be) platform-
3014    independent.)
3015    
3016    The installer can now install everything under Win32
3017    as well as under *nix as long as it compiles.
3018    
3019    Other changes:
3020    
3021      - made CML compile again under Win32
3022      - made eXene compile under Win32 (by providing a fake structure UnixSock
3023        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3024      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3025        same as type int;  under Win32 it isn't
3026      - fixed some slice-related problems in the win32-specific parts of CML
3027      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3028        (under Win32, the volume name is case-insensitive, and the
3029        OS.Path code compares volume names for equality)

3046    Description:
3047    
3048      1. Changed interface to vectors and arrays in Basis to match
3049         (draft) Basis spec.
3050      2. Added signatures and implementations of slices according to
3051         Basis spec.
3052      3. Edited source code throughout the system to make it compile again
3053         under 1. and 2.  (In some cases code had to be added to have it
3054         match the new signatures.)
3055      4. MLRISC should be backward-compatible: the copies of the originals
3056         of files that needed to change under 3. were retained, the .cm files
3057         check the compiler version number and use old versions when
3058         appropriate.
3059      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3060         dirstream -> string option (in accordance with Basis spec).
3061      6. When generating code that counts lines, ml-lex used function
3062         CharVector.foldli, taking advantage of its old interface.
3063         This has been replaced with the corresponding code from
3064         CharVectorSlice.  (html-lex must be re-lexed!)
3065      7. BitArray in smlnj-lib/Util has been extended/modified to match the
3066         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
3067      8. Removed temporary additions (fromInternal, toInternal) from the
3068         (now obsolete) IntInf in smlnj-lib/Util.
3069      9. Cleaned up structure Byte.
3070     10. Added localOffset, scan, and fromString to Date (according to spec).
3071         Cleaned/corrected implementation of Date.
3072         (Still need to check for correctness; implement better canonicalizeDate.)
3073     11. Added "scan" to signature IEEE_REAL.
3074     12. Some improvements to IntInf [in particular: efficiency-hack for
3075         mod and rem when second operand is 2 (for parity checks).]
3076     13. Changed representation of type Time.time, using a single IntInf.int
3077         value counting microseconds.  This considerably simplified the
3078         implementation of structure Time.  We now support negative time
3079         values; scan and fromString handle signs.
3080     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3081         ArraySlice).

3087    Description:
3088    
3089    This is a major update which comes with a version number bump
3090    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3091    and an implementation of IntInf in the Basis.
3092    
3093    There are a fairly large number of related changes and updates throughout
3094    the system:
3095    
3096    Basis:
3097            - Implemented IntInf.
3098            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3099            - Added some missing Real64 operations, most notably Real.toLargeInt.
3100            - Added FixedInt as a synonym for Int32.
3101    
3102    compiler:
3103            * Added support for a built-in intinf type.
3104              - literals
3105              - pattern matching
3106              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3107              - overloading on literals and operations
3108    
3109            This required adding a primitive type intinf, some additional
3110            primops, and implementations for several non-trivial intinf
3111            operations in Core.  (The intinf type is completely abstract
3112            to the compiler; all operations get delegated back to the Core.)
3113    
3114            * Intinf equality is handled by polyequal.  However, the compiler
3115            does not print its usual warning in this case (since polyequal
3116            is the right thing to do there).
3117    
3118            * Improved the organization of structure InlineT.
3119    
3120            * A word about conversion primops:
3121            If conversions involving intinf do not cancel out during
3122            CPS contract, then the compiler must insert calls to Core functions.
3123            Since all core access must be resolved already during the FLINT
3124            translate phase, it would be too late a the time of CPS contract
3125            to add new Core calls.  For this reason, conversion primops
3126            for intinf carry two arguments:  1. the numeric argument that
3127            they are supposed to convert, and 2. the Core function that
3128            can help with this conversion if necessary.  If CPS contract
3129            eliminates a primop, then the associated Core function becomes
3130            dead and goes away.  Intinf conversion primops that do not get
3131            eliminated by CPS contract get rewritten into calls of their
3132            core functions by a separate, new phase.
3133    
3134    interactive system:
3135            - Control.Print.intinfDepth controls max length of intinf constants
3136            being printed. (Analogous to Control.Print.stringDepth.)
3137            - Cleanup in printutil and pputil: got rid of unused stuff and
3138            duplicates; replaced some of the code with code that makes better
3139            use of library functionality.
3140    
3141    CM:
3142            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3143            are no longer silent.
3144    
3145    CKIT:
3146            Fixed mismatched uses of Int32 and LargeInt.  I always decided
3147            in favor of LargeInt -- which is now the same as IntInf.
3148            CKIT-knowledgable people should check whether this is what's
3149            intended and otherwise change things back to using Int32 or
3150            FixedInt.
3151    
3152    Throughout the code:
3153            Started using IntInf.int literals and built-in operations
3154            (e.g., comparison with 0) where this seems appropriate.

3161    Description:
3162    
3163    Merging changes from the mcz-branch development branch into trunk.
3164    These changes involve replacement of the emulated old prettyprinter
3165    interface with direct use of the SML/NJ Lib PP library, and fixing
3166    of a couple of bugs (895, 1186) relating to error messages.  A new
3167    prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
3168    has been added.

3174    Description:
3175    
3176    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
3177    
3178        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3179    
3180    This patch restores SML/NJ's ability to run under win32.  There are a
3181    number of changes, including fixes for several bugs that had gone
3182    unnoticed until now:
3183    
3184      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3185        trying to run the win32 version from within cygwin.)
3186    
3187      - There are a number of simple .bat scripts that substitute for their
3188        corresponding Unix shell-scripts.  (See below.)
3189    
3190      - The internals of ml-build have been modified slightly.  The main
3191        difference is that instead of calling ".link-sml" (or link-sml.bat)
3192        using OS.Process.system, the ML process delegates this task back
3193        to the script.  Otherwise problems arise in mixed environments such
3194        as Cygwin where scripts look and work like Unix scripts, but
3195        where OS.Process.system cannot run them.
3196    
3197      - In CM, the srcpath pickler used native pathname syntax -- which
3198        is incorrect in the case of cross-compilation.  The new pickle format
3199        is independent of platform-specific naming conventions.
3200    
3201      - Path configuration files (such as lib/pathconfig) can now choose
3202        between native and standard syntax.  Placing a line of the form
3203    
3204            standard!
3205    
3206        into the file causes all subsequent paths to be interpreted using
3207        CM standard pathname syntax (= Unix conventions); a line
3208    
3209            native!
3210    
3211        switches back to native style.  This was needed so that
3212        path config files can be written portably, see src/system/pathconfig.
3213    
3214      - Runtime system:
3215    
3216          - win32-filesys.c:  get_file_time and set_file_time now
3217            access modification time, not creation time.
3218    
3219          - I/O code made aware of new array representation.
3220    
3221          - Bug fixes in X86.prim.masm.
3222    
3223       - src/system/makeml made aware of win32. (For use under cygwin
3224            and other Unix-environments for windows.)
3225    
3226       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3227         which caused BinIO.inputAll to fail consistently.
3228    
3229    .bat scripts:
3230    
3231       Windows .bat scripts assume that SMLNJ_HOME is defined.
3232    
3233       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
3234         applications (sml, ml-yacc, ml-lex).
3235       - ml-build.bat: analogous to ml-build.
3236       - config\install.bat:  Analogous to config/install.sh.  This requires
3237         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3238         (nmake etc. must be on the path, and vcvars32 must have been run.)
3239         Moreover, sources for ml-lex and ml-yacc need to exist under src,
3240         and the bootfile hierarchy must have been unpacked under
3241         sml.boot.x86-win32.
3242         The script is very primitive and does a poor job at error checking.
3243         It only installs the base system, ml-lex, and ml-yacc.  No other
3244         libraries are being installed (i.e., you get only those that
3245         are part of the compiler.)
3246       - link-sml.bat:  analogous to .link-sml, but not currently used
3247    
3248    Unrelated bug fixes:
3249    
3250      - ml-nlffigen now exports structures ST_* corresponding to incomplete
3251        types.
3252      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
3253        otherwise.)

3277    Description:
3278    
3279    Two changes:
3280    
3281      1. Added a flag for controlling whether non-exhaustive bindings will
3282         be treated as errors (default is false).
3283      2. Cleaned up the *entire* source tree so that CMB.make goes through
3284         without a single non-exhaustive match- or bind warning.

3290    Description:
3291    
3292    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3293    
3294       This mainly affects the quality of error messages.  However, some
3295       of the code is now more straightforward than before. (Treatment of
3296       the above four constructs in translate.sml is much simpler than
3297       the "macro-expansion" that was going on before.  Plus, the mach-
3298       compiler no longer gets invoked just to be able to compile an
3299       if-expression.)
3300    
3301    2. The ErrorMsg.Error exception is now caught and absorbed by the
3302       interactive loop.

3313       o getnetbyname, getnetbyaddr: these functions seem to be missing in
3314         the Cygwin library.
3315       o Ctrl-C handling may be flaky.
3316       o Windows system calls and Windows I/O are not supported.
