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

153    
154    After Aaron Turon's bug fix for ml-ulex (handling the ^ character
155    in legacy mode), re-ran the lexer generator on all lex input files
156    and committed the results.
157    
158    This should fix the problem with ckit and nlffi that was reported
159    by Vesa A. Norrman.

174    
175    3rd merge of base from primop-branch-3 into the trunk.
176    Additional bug fixes included:
177    
178     * Timer.cpu_timer, etc. type printing corrected (by making
179         Timer have opaque sig constraint in basis/Implementation/timer.sml)
180     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by

186    Description:
187    
188    Fixed some bugs in new Div code in FLINT/trans/translate.sml.
189    
190    Also, changed the handling of "no core access":  When translate.sml
191    needs access to a core exception at a time when the core has not
192    been set up yet (this only happens when compiling system/smlnj/init/*),
193    then don't bother generating the corresponding tests.
194    
195    The old scheme was to generate a bogus value to be used in place of
196    the exception.  Unfortunately, that confuses the plambda type checker.
197    Moreover, it does not do any good, because at runtime we don't expect
198    such an exception to be ever raised.  (The code in system/smlnj/init/*
199    has to be written very carefully with this in mind!)

211    Description:
212    
213    FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
214    with an explicit test for zero division.  This should fixes several
215    regressions and makes it possible for downstream optimization phases
216    to treat these operations as "pure" when they are applied to unsigned
217    operands.

224    Added the new MLRISC code generator for the AMD64.  This version,

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

239    Date: 2007/05/23 22:30:00 CDT
240    Description:
241    
242    CMB (and CM) now automatically defines the CM "preprocessor" symbol
243    NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
244    
245      (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
246       CM_SLAVE_MODE is defined in attached slaves while running CM.make
247       or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
248       while running CMB.make.  The point is that the single symbol
249       NO_PLUGINS is definde in all three cases.)
250    
251    I changed the three locations within the sources that get compiled
252    during CMB.make where ml-yacc or ml-lex input is processed: When
253    NO_PLUGINS defined, then the use of the mlyacc and mllex tools
254    is bypassed.
255    
256    When bootstrapping new versions of the compiler, there can be
257    situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
258    are not available or otherwise not operational.  In this case one can
259    manually define the NO_PLUGINS symbol prior to running CMB.make().  To
260    do so, the following command should be issued at the interactive
261    prompt:
262    
263       #set (CMB.symval "NO_PLUGINS") (SOME 1);
264    
265    A CMB.make with NO_PLUGINS defined relies on the existence of the
266    files that normally would be generated by ml-yacc and ml-lex.
267    (Copies of these files are in the repository.)

275    2nd merge of base from primop-branch-3 into the trunk.

283    Description:
284    
285    Changed the installation mechanism for CM tool plugins.  These are
286    just libaries and now get installed like ordinary libaries.
287    
288    There are now a number of new installation targets that give some
289    fine-grain control over what classes and suffixes are known, and what
290    they will map to.
291    See config/targets for details.
292    
293    The code that caused plugin installation as part of running a
294    tool's "build" script has been removed.  (The build script is for
295    building, not for installing.)

300    Description:
301    
302    Added a boolean control named cm.tolerate-tool-failures (env. variable
303    name: CM_TOLERATE_TOOL_FAILURES).  The default is false and makes
304    CM fail if a shell tool reports a non-success exit status.  If
305    the control is set to true, then CM will press on after tool failures
306    in the event that the target files exist (even though they are
307    considered outdated).  Turning the control to true can be useful for
308    bootstrapping.

313    Description:
314    
315    Merge of ml-lpt revisions for 110.64.
316    
317    The name of several ml-lpt-lib modules has changed:
318      Repair        => AntlrRepair
319      StreamPos     => AntlrStreamPos
320      ErrHandlerFn  => AntlrErrHandler
321      EBNF          => AntlrEBNF
322    
323    The ml-antlr specification format has changed: declarations such as
324    %tokens and nonterminal definitions can occur *multiple* times in the
325    same specification.  The semantics are such that each new declaration
326    extends the previous ones.  This does not apply to %start or %name,
327    of course.
328    
329    Importing a grammar via %import now includes *all* declarations in from
330    the imported grammar, except for %name, %entry, and %start.  Tokens
331    and nonterminals can be dropped using the new %dropping clause of the
332    %import directive; the separate %drop and %extend have been removed.
333    
334    We now allow optional type annotations on nonterminals, using the %nonterms
335    directive as in ml-yacc.
336    
337    The refcell construct is now implemented using SML's regular reference
338    cells, so the :== and !! notation has been deprecated.
339    
340    The ml-antlr tool now does much more checking of specifications, and
341    its error messages have been greatly improved.  Error repair for
342    generated parsers has been completely rewritten, and is now both
343    much faster and more accurate.
344    
345    ml-ulex is now more lenient with escape codes (non-SML-standard
346    escape codes are now interpreted literally, so e.g. \| denotes "|").
347    Also, character classes may now include a "-" character at the beginning
348    as is standard in most other regexp tools.
349    
350    All of these changes are documented in the user guide, which has
351    been updated and improved with this merge.

503    
504    Added preliminary support in MLRISC for Staged Allocation, a technique
505    for specifying calling conventions (see
506    http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
507    Initially, we plan to use this code to generate C calls for the AMD64.
508    
509    The staged allocation code base resides in MLRISC/staged-allocation,
510    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

576    
577    Brought ml-lpt manual up-to-date with the code.  Many minor
578    improvements to the tools, and a few minor bugfixes.  Prepared
579    ml-lpt-lib for integration with new UTF8 structure.  Changed
580    the interface for creating streams in ml-ulex (we now support
581    stream creation from several kinds of sources).  Overall, the
582    tools are now quite stable, and their interfaces are unlikely to
583    change in a way that would break compatibility.  More work,
584    however, is needed in the documentation.

589    Description:
590    
591    Implemented library installer.  Moved CM plugin code for
592    ml-burg, ml-lex, and ml-yacc out of CM source tree and into
593    their respective trees.  Implemented CM plugin for ml-ulex
594    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
595    and ml-antlr.
596    
597    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
598    CM tools.  (It turns out to be too messy to do otherwise because
599    there is too much code that during installation relies on the presence
600    of these tools -- resulting in a tricky ordering problem.)

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

680    Description:
681    
682    Added code to CM's "standard shell tool" implementation which
683    causes it to tolerate (with a warning) the situation where the shell
684    command fails (e.g., due to the shell command's non-existence)
685    as long as all target files exist.
686    
687    This makes it possible to, e.g., build ml-yacc from sources even if
688    svn checkout messed up the time stamps on files in such a way that
689    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
690    be needed to re-process yacc.grm, but obviously it might not yet be
691    available at that time.)

731    Description:
732    
733    New working release (110.60).  NEW BOOTFILES!
734    
735    This is the first subversion-hosted release.  There are also changes
736    to the directory layout.  Here is a table:
737    
738    (All pathnames are relative to the SML/NJ "root" directory.)
739    
740      config -> config
741    
742      src/cm -> base/cm
743      src/compiler -> base/compiler
744      src/runtime -> base/runtime
745      src/system -> base/system
746    
747      src/cm/pgraph -> pgraph
748    
749      src/READMES -> base/READMES
750      src/$notefile -> base/NOTES/$notefile
751         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
752                           MACOSXINSTALL WININSTALL
753    
754      src/smlnj-lib -> smlnj-lib
755      src/MLRISC -> MLRISC
756      ckit -> ckit
757      src/cml -> cml
758      src/eXene -> eXene
759      src/heap2asm -> heap2asm
760      src/lexgen -> lexgen
761      src/ml-burg -> ml-burg
762      src/ml-lex -> ml-lex
763      src/ml-yacc -> ml-yacc
764      src/ml-nlffi-lib -> nlffi/lib
765      src/ml-nlffigen -> nlffi/gen
766      src/smlnj-c -> smlnj-c
767      src/tools/TraceDebugProf -> trace-debug-profile
768    
769    In addition, there is also a new
770    
771      ml-lpt
772    
773    directory containing two new program generator tools: ml-ulex and
774    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
775    LL(k) parser generator). These tools are currently "beta-quality"
776    
777    The latest versios of the sources can now be obtained anonymously
778    via subversion.  For this, it is useful to first check out
779    
780       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
781    
782    and put the resulting directory on your shell's PATH.  This provides
783    access to three shell scripts: checkout-all.sh, stat-all.sh,
784    and refresh-all.sh.
785    
786    To create a freshly checked-out copy of the sources, do
787    
788       checkout-all.sh [dir]
789    
790    where dir is the optional SML/NJ root directory (default is ".").
791    
792    This creates the above directory layout.  Each subdirectory of
793    the root is under individual subversion control.  The stat-all.sh
794    and refresh-al.sh scripts apply "svn stat" or "svn update" to
795    each of these subtrees.
796

799    Date: 2006/11/02 12:20:00 CST
800    Description:
801    
802    Reorganized directory layout.
803    
804    This is a temporary solution, more reorganization is to come.
805    
806    The basic idea is to have a number of toplevel trees, each corresponding
807    to a well-defined part of the overall system.  Each part can be
808    maintained individually, even in separate source repositories,
809    although currently we still serve everything out of the main
810    smlnj-gforge tree.
811    
812    Installer and and scripts have been updated to reflect the new
813    layout.  The installer (base/src/system/smlnj/installer) is now
814    "scriptable" to avoid burning too much knowledge about the
815    layout into SML source code.  The main script used by the installer
816    is in config/actions.
817    
818    The main change is that many of the subdirectories of what used to
819    be known as "src" have moved to the toplevel.  The "src" directory
820    itself has moved down into a subtree called "base".  (We may eventually
821    get rid of the extra level of indirection represented by "src".)
822    
823    The layout is now as follows:
824    
825      toplevel tree name | default repository
826                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
827      -------------------+----------------------------------------------------
828      config             | $gf/config/trunk
829                         |
830      base               | $gf/sml/trunk
831                         |
832      smlnj-lib          | $gf/smlnj-lib/trunk
833      MLRISC             | $gf/MLRISC/trunk
834                         |
835      ml-yacc            | $gf/ml-yacc/trunk
836      ml-lex             | $gf/ml-lex/trunk
837      ml-burg            | $gf/ml-burg/trunk
838      lexgen             | $gf/lexgen/trunk
839      heap2asm           | $gf/heap2asm/trunk
840                         |
841      cml                | $gf/cml/trunk
842      eXene              | $gf/eXene/trunk
843      ckit               | $gf/ckit/trunk
844      nlffi              | $gf/nlffi/trunk
845                         |
846      smlnj-c            | $gf/smlnj-c/trunk
847    
848    In $gf/admin there are a few useful shell scripts for checking out
849    and maintaining the entire collection of trees:
850    
851       admin/checkout-all.sh [dir]
852          -- optionally creates dir and checks out all trees from their
853             default repositories; if dir is missing, checkout into .
854       admin/refresh-all.sh [dir]
855          -- looks at all trees (from the above list) in dir (default: .)
856             and runs "svn update" if the tree exists and is under
857             subversion control;
858             non-existing or non-subversion trees are skipped
859       admin/stat-all.sh [dir]
860          -- like refresh-all.sh, but runs "svn stat" instead

892          way that ml-lex does
893    
894        * lexgen propagates exceptions the same way that ml-lex does
895    
896      CML:
897        * Fixed a bug in the SyncVar polling functions (iGetPoll,
898          mTakePoll, and mGetPoll) that could lead to livelock.

1008    Hooked code for Darwin-specific Intel ABI into main compiler.
1009    (This is a temporary solution which relies on the fact that the
1010    compiler itself does not use NLFFI.  Eventually we need to divorce
1011    intel mac from generic x86 unix code and make separate sets of binaries.)

1040    Description:
1041    
1042    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
1043    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
1044    at the time when config/preloads is processed, the library has to
1045    be referred to by another name.  In 110.57 this would be
1046    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
1047    to be valid as well.)

1102    Tag: blume-22051115-versiontool
1103    Description:
1104    
1105    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
1106    file gets loaded as a tool -- by the equivalent of CM.make during the
1107    run of CMB.make.  Thus, CMB's path configuration is meaningless for
1108    it.  Instead, it has the status of "user code", so it should use
1109    $/basis.cm to refer to the Basis library.  (At least that's true for
1110    the purpose of bootstrapping the previous change.  In the future it
1111    might make sense to have versiontool.cm refer to
1112    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1113    compiler itself uses.)
1114    
1115    Also patched src/system/testml to have it activate those extra anchor
1116    bindings in config/extrapathconfig.

1121    Tag: blume-22051115-libraries
1122    Description:
1123    
1124    This change affects the way the following libraries are tied into
1125    the system:
1126    
1127       $/basis.cm
1128       $/smlnj-lib.cm
1129       $/pp-lib.cm
1130       $/controls-lib.cm
1131       $/html-lib.cm
1132       $/ml-yacc-lib.cm
1133    
1134    These libraries are now internally (as seen from the source code
1135    of the implementation itself) known by the following names:
1136    
1137       $smlnj/basis/basis.cm
1138       $smlnj/smlnj-lib/smlnj-lib.cm
1139       $smlnj/smlnj-lib/pp-lib.cm
1140       $smlnj/smlnj-lib/controls-lib.cm
1141       $smlnj/smlnj-lib/html-lib.cm
1142       $smlnj/ml-yacc/ml-yacc-lib.cm
1143    
1144    This makes it possible to work with code that requires different
1145    versions of these libraries, and which refers to these libraries using
1146    their "default" names (i.e., the first set of names above).  In other
1147    words, one can un-define or re-define those default names without
1148    compromising the proper functioning of the compiler itself.
1149    
1150    A similar procedure had already been performed for several of the
1151    MLRISC libraries that are linked into the compiler.  I did some
1152    cleanup on this code.
1153    
1154    A new file in the config directory (named extrapathconfig) is
1155    responsible for setting up path anchors that the compiler itself does
1156    not need, but that are typically required by user code.

1336    Description:
1337    
1338    Added mechanism for re-creating a heap file for the interactive system
1339    after configuration variables have been changed.
1340    
1341       CM.redump_heap : string -> unit
1342    
1343    This is much like SMLofNJ.exportML, but starting from the resulting
1344    heap does not return to the caller of CM.redump_heap but
1345    restarts the interactive system from scratch.  The original call of
1346    CM.redump_heap does not return but ends the interactive session.
1347    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1348    
1349    Internally, redump_heap winds the dynamic execution context back to
1350    the point where the original heap image was created and re-executes
1351    the heap image generation code in the boot code.

1370    the flag "check-gc".  "debug-check-gc" turns on the verbose mode.

1467    Tag: blume-20050114-heap2exec
1468    Description:
1469    
1470    Implemented new (but still experimental) heap2exec facility.  This is
1471    tested under Mac OS X and should work under Linux (will test shortly).
1472    It will probably also work on the Sparc (will test some time later).
1473    
1474      - removed old "HACKED_STANDALONE" hack from runtime
1475    
1476    To be able to test this, uncomment the request for "heap2asm" in
1477    config/targets prior to installation.  (Notice that this is different
1478    from "heap2exec" mentioned below.  Not a typo.)
1479    
1480    To perform an actual test, run the command
1481    
1482       $ bin/heap2exec heapfile execfile
1483    
1484    (You can put heap2exec on your shell's path.)
1485    
1486    For example, run
1487    
1488      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1489    
1490    This will create a standalone executable called "mly" which you can
1491    then invoke directly as a command.

1636    Tag: blume-20041124-position
1637    Description:
1638    
1639    The compiler can now be compiled in a mode that makes structure Position
1640    equal to Int64.  The default, however, is unchanged (Position = Int31)
1641    for the time being.
1642    
1643    To enable 64-bit positions, use the following procedure:
1644    
1645    1. Start sml
1646    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1647    3. Type
1648          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1649    4. Run CMB.make() as usual.
1650    
1651    This is barely tested.  The only test so far was a little SML program
1652    counting the number of characters in an 8-gigabyte file by
1653    reading it character-by-character.  That test was successful.
1654    
1655    In support of 64-bit positions, a number of new functions have been
1656    added to the runtime system.

1701    
1702    - In a previous commit, fixed a minor issue with how polyequal is being
1703      translated.  In particular, the code now "looks through" abstractions.
1704      This results in slightly fewer polyEqual warnings and hopefully slightly
1705      more efficient code.  Important examples for where this matters are
1706      the new int64 and word64 types.

1723    All the pieces of Word64 are now there, with the exception of the

1725    but for the time being they don't even make sense because LargeWord is
1726    32-bit wide.)
1727    
1728    Also started to add similar support for Int64, but major pieces of that
1729    are still missing.

1735    Description:
1736    
1737    Structure Word64 is now (almost) complete, word literals and patterns
1738    seem to work.  There are a few odd pieces missing.  In particular,
1739    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1740    at the moment.
1741    
1742    Making Word64 official would mean that LargeWord becomes Word64.  But
1743    this requires extreme care because most word-word conversions have to
1744    go through LargeWord, so making a mistake means loss of efficiency or
1745    worse.  Eventually there will be a solution similar to (but actually
1746    simpler than) what I did with IntInf.

1779        containing the URL string into a file containing
1780        shell script code.  The code has access to the $VERSION variable.
1781      - Made corresponding changes to config/install.sh and config/unpack.
1782      - Default contents of config/srcarchiveurl uses $VERSION and
1783        normally does not have to be edited to reflect a version change.
1784    
1785      (As a result, a version change can be done by just editing
1786       config/version, the rest is now automatic.)

1806      - added a missing LOAD in the code that deals with struct arguments
1807      - made sure the caller does not add the wrong number of bytes to the
1808        stack pointer after a call of a function returning a struct
1809        (the callee already pops the implicit argument which points to
1810         the space reserved for the result)

1826    Tag: blume-20041020-standalone-backtrace
1827    Description:
1828    
1829    Added a mechanism for getting back-trace information from standalone
1830    programs.  Here is how it works:
1831    
1832       1. The part of the program from which you want to get backtrace
1833          information (usually the whole program) should be wrapped with
1834          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
1835          main program could be modified from something like
1836    
1837             fun main (pgm, args) = ...
1838    
1839         to
1840    
1841            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1842    
1843       2. To be able to access BackTrace.monitor, you have to add
1844          library $smlnj-tdp/plugins.cm to the .cm file that contains your
1845          main function.
1846    
1847       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1848          CM might have created in the past for your project).
1849    
1850       4. Build the system using this command line:
1851    
1852             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1853                      myprog.cm MyProg.main myprog
1854    
1855          instead of the usual
1856    
1857             ml-build myprog.cm MyProg.main myprog
1858    
1859    I changed a library name:
1860    
1861       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1862    
1863    New libraries:
1864    
1865       $smlnj-tdp/back-trace.cm
1866          -- when loaded causes the back-trace plugin to be installed
1867       $smlnj-tdp/coverage.cm
1868          -- when loaded causes the coverage plugin to be installed

1884    Description:
1885    
1886    * Test coverage tool added!
1887    * Further reorganization of tracing-, debugging-, and profiling support:
1888    
1889        - moved original BTImp -- now called BackTrace -- into a separate
1890          library called $/trace-debug-profile.cm
1891        - eliminated all mentions of BTrace from SMLofNJ.Internals
1892        - only the instrumentation mechanism is now left in the compiler proper
1893        - BackTrace module is a plugin which is NOT plugged in by default
1894        - Coverage module is another such plugin
1895    
1896    To get the benefits of any of these plugin modules, the code in
1897    question must be compiled with tdp instrumentation turned on.  This
1898    can be done by setting SMLofNJ.Internals.TDP.mode to true.
1899    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1900    
1901    Plugins are selected at link time.  (Pre-compiled instrumented code
1902    can be re-loaded with different plugins in effect.)  When an
1903    instrumented module is linked, whatever plugins are at that time
1904    enabled will come into effect for that module.
1905    
1906    To enable the back-trace plugin, load library $/trace-debug-profile.cm
1907    and invoke BackTrace.install() (e.g., from the interactive prompt).
1908    To enable the coverage plugin, load the same library and invoke
1909    Coverage.install().
1910    
1911    Back-traces are generated automatically on uncaught exceptions and
1912    when the code in question explicitly invokes BackTrace.trigger().
1913    
1914    Coverage (and execution frequency-) information must be queried
1915    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

1932    Some rationalization of names:

1937    This is is preparation of using the original back-trace
1938    instrumentation for other purposes.  "TDP" stands for
1939    Trace/Debug/Profile.
1940    
1941    The control flag controlling whether instrumentation is on or off is now
1942    registered under a different name, so instead of running sml as
1943    
1944     sml -Cinstrument.btrace-mode=true
1945    
1946    one has to say
1947    
1948     sml -Ctdp.instrument=true

1964    Description:
1965

1967    treats subsequent occurrences of "group", "library", "source", "is",
1968    "*", and "-" as ordinary identifiers rather than keywords.
1969    
1970    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
1971    is supposed to accept a tool argument called "source", but this did
1972    not work because of the clash with the keyword.

2016    
2017    * Moved the "version" magic into its own little library under

2019      a stable src/compiler/core.cm.
2020    
2021    * At the same time, structure CompilerVersion is now known as
2022      structure SMLNJVersion.
2023    
2024    * Arranged for the version tool to NOT kick in when rebuilding the system
2025      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
2026      Also, loading the versiontool does not work when rebuilding the system
2027      because CM is not properly initialized at that time.

2032    Tag: blume-20040929-autoversion
2033    Description:
2034    
2035    Implemented some CM magic to have
2036        file src/compiler/TopLevel/main/version.sml
2037    generated automagically.
2038    The version is taken from two files: config/version and config/release.
2039    The first is expected to contain a two-part version number such as 110.49.
2040    The second should contain a single number, but it may be missing.
2041    
2042    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2043    time the version tool is loaded (which is the first time you say CMB.make),
2044    then the tool will increment the value stored in config/release every
2045    time CMB.make is invoked.
2046    
2047    The binfile format is now insensitive to anything beyond the first
2048    two components of a version number, so bumping the release does not render
2049    binfiles incompatible.  Auto-bumping can be used to keep track of versions
2050    during development without invalidating existing binfiles.
2051    
2052    In any case, every CMB.make updates the date information in version.sml.
2053    (This is the date that is printed in the banner.)

2066    Tag: blume-20040927-controls
2067    Description:
2068    
2069    Added two pieces of functionality to the Controls interface:
2070    
2071    1.   val save'restore: 'a control -> unit -> unit
2072    
2073       grabs the current value of the control in stage 1 and restores it
2074       in stage 2.
2075    
2076    2.   val set' : 'a control * 'a -> unit -> unit
2077    
2078       stores the given value into the control in stage 2 (i.e., delayed)
2079       but does all error checking in stage 1.
2080       (This is for string controls that need to do parse their argument --
2081        something that might fail.  In some cases, notably in CM, one
2082        already knows the intended argument but wants to delay the actual
2083        assignment until a time when error recovery would be more difficult.)
2084    
2085    Changed the handling of controls in tool arguments to classes "sml" and
2086    "lazysml":
2087       - use Controls.save'restore as a more robust way of restoring the
2088         old value (in particular: without having to re-parse the string)
2089       - use controls to handle the "overload" keyword in the init group
2090         (I believe this change actually fixes a long-standing obscure bug.)

2095    Tag: blume-20040927-lazysml
2096    Description:
2097    
2098    Added a new tool class called "lazysml" to CM's tool chest.  The only
2099    difference to "sml" is that compilation is done with Control.lazysml
2100    set to true.  A source of class "lazysml" is automatically recognized
2101    by a file name suffix of ".lml".
2102    
2103    In addition to the above feature, the original class "sml" now also
2104    supports a tool argument "lazy" which has the same effect.  As a
2105    result, the following three lines are equivalent:
2106    
2107        foo.sml : lazysml
2108        foo.sml : sml (lazy)
2109        foo.sml (lazy)
2110    
2111    The setting goes into effect both during parsing and during
2112    compilation.  The original setting is restored right after parsing and
2113    after compilation, respectively.
2114    
2115    In addition to all the above, there is also a general mechanism to set
2116    ANY of the "controls" that are available at the command line via
2117    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
2118    apply as well. (In fact, "lazy" is implemented as a special case of
2119    the general mechanism.)
2120    
2121    The .cm file syntax uses a new keyword tool argument called "with".
2122    There are several ways of indicating the desired settings:
2123    
2124        foo.sml (with:parser.quotations=true)
2125        foo.sml (with:(name:parser.quotations value:true))
2126        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2127        foo.sml (with:(name1=value1 name2=value2 ...))
2128        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2129    
2130        etc.
2131    
2132    Another possible abbreviation is to leave out the =v or value:v part
2133    if the name refers to a boolean control (in which case the value is
2134    taken to be true).  Thus, one could get lazy sml also by saying:
2135    
2136        foo.sml (with:parser.lazy-keyword=true)
2137        foo.sml (with:parser.lazy-keyword)
2138        foo.sml (with:(name:parser.lazy-keyword value:true))
2139        foo.sml (with:(name:parser.lazy-keyword))

2491    Description:
2492    
2493    Changed the interface of structures Timer and Unix to match the most
2494    recent Basis spec.
2495    
2496    In the case of Unix there still seems to be an open/weird issue:
2497    
2498       The {text,bin}{In,Out}streamOf functions are supposed to create
2499       fresh streams whenever they are called -- as opposed to have them
2500       return the same stream every time.  This design is supposed to
2501       prevent space leaks caused by proc values hanging on to streams.
2502    
2503       The reap function, on the other hand, is supposed to close the
2504       streams.  This cannot be done without having a handle on the
2505       stream in proc after all...
2506    
2507    I took the liberty to implement the following stopgap solution:
2508    
2509      The proc value hangs on to the most recently created stream(s).
2510      Reap closes those.  If either or both of the two streams hadn't
2511      been created at all yet, then reap will close the corresponding
2512      file descriptors directly.
2513    
2514    PS: I don't understand the original space leak argument anymore.  If
2515    a proc hangs on to the imperative stream, then I/O operations on those
2516    will advance the state of the cached stream and avoid the space leak.

2530    Description:
2531    
2532    CM now ignores (but still accepts) the "owner" information in group
2533    descriptions.  The owner of a group is its next enclosing
2534    library. Each group must have a unique owner.  (There is a virtual
2535    "toplevel" library that owns groups which are not nested within a real
2536    library.)  Previously, each group had to explicitly declare its owner,
2537    and CM would check that such a declaration is correct.  The new scheme
2538    is to have CM check that for each group there is precisely one owning
2539    library.
2540    
2541    The advantage of the new scheme is that the programmer no longer needs
2542    to maintain the somewhat annoying owner information.  The downside is
2543    that CM cannot enforce the ownership rule across multiple runs of
2544    CM.make.  Fortunately, enclosing the same group in two different
2545    libraries A and B which are not part of the same program does not
2546    cause real problems.

2567    Arranged for ml-build to clean up after itself a little bit better.
2568    The script generates a temporary SML source file and compiles it using
2569    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
2570    gets rid of those at the end, so they don't accumulate under .cm.
2571    
2572    This required a minor change to install.sh because the name of the
2573    metadata directory (default: .cm) is actually configurable at
2574    installation time.

2589    Description:
2590    
2591    Added previously missing support for many socket-related functions
2592    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
2593    for the voluminous patch!
2594    
2595    (I have not tested this patch under win32 yet.)
2596    
2597    Here is David's e-mail:
2598    
2599    Hi,
2600    
2601    Attached to this email you find a diff against sml/nj 110.45
2602    that will enable socket support under Windows.
2603    
2604    To apply the patch (using unix or cygwin)
2605    1) gunzip runtime.diff.gz
2606    2) "cd" into "src/runtime" in the source tree of a fresh
2607       110.45 installation.
2608    3) patch -p 1 < [your/path/to]runtime.diff
2609    
2610    The code compiles fine but has NOT yet been extensively tested.
2611    I only ran a few tests for basic socket client functionality
2612    (which worked fine).  Especially the functions that use ioctl
2613    are not tested at all and might not work (see below).
2614    
2615    I implemented this since we want to move to a newer version of sml/nj
2616    but need socket support in order to use it.  This is the first time I
2617    even had a look at the sml/nj source,  so please review my changes
2618    before making this part of the distribution!  Here are a few issues
2619    that I think might be better for someone to solve who is more
2620    familiar with the sml/nj source (and socket programming):
2621    
2622    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2623      exception since I could not figure out what the windows equivalent
2624      of these functions is
2625    
2626    - In sockets-osdep.h there are a some #include statements that are
2627      only used in a few files that include sockets-osdep.h
2628    
2629    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2630      does not process its return value since I don't know how to
2631      report an error upwards.
2632    
2633    - It would probably be good to have a call to WSACleanup() when
2634      the library is unloaded (if there is such a possibility).
2635      Otherwise I think Windows will take care of this automatically
2636      when the process finishes.
2637    
2638    - I used ioctlsocket() as a replacement for ioctl() but I have
2639      no idea if that is actually the proper replacement on Windows.
2640    
2641    - All these issues are marked in the code by "FIXME" comments.
2642    
2643    We use sml/nj extensively in our products and are quite happy
2644    with it.  I hope this contribution will help you.
2645    
2646    Keep up the good work!
2647

2681    Description:
2682    
2683    The installer now honors the "src-smlnj" target again, although its meaning
2684    has changed from "all sources required for the compiler" to "all sources
2685    the installer knows about".  In other words, if you enable "src-smlnj"
2686    in the "targets" file, then the installer will pull in sources for
2687    everything.  (Notice that this refers to source code only.  Compiled
2688    code is still only installed for modules that were requested explicitly
2689    or which are required for other modules that were requested explicitly.)

2723    Description:
2724    
2725    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
2726    of SML/NJ.  The problem is that
2727    
2728       lib = dlopen(NULL, ...)
2729       f   = dlsym(lib, "malloc");
2730    
2731    does not work on Windows unless we explicitly export symbols
2732    such as 'malloc' during linking.  We fixed this by explicitly
2733    exporting the required symbols with the magic gcc incantation:
2734    
2735        -Wl,--export-all cygwin.def
2736    
2737    where cygwin.def is a file containing all the symbols that
2738    we wish to export.
2739    
2740    I suspect this is a Windows problem and we'll have to
2741    do the same (somehow with windows compilers) when
2742    we build the native win32 version with the system
2743    calls LoadLibrary/GetProcAddress.

2813    Eliminated the "dont_move_libraries" directive in config/targets.
2814    (The mechanism was broken and could not be fixed easily.  Moreover,
2815    there does not seem to be any reason not to move all libraries into
2816    lib during installation.  I originally implemented this directive as a
2817    backward-compatibility feature when I first introduced the new CM.
2818    Now that things have been stable for a long time and going back to the
2819    old CM is not an option, there is no reason to keep it around.)

2869    Description:
2870    
2871    I modified the read-eval-print loop so that the autoloader gets
2872    invoked whenever the prettyprinter tries to look up a symbol that
2873    is not currently defined in the toplevel environment but which
2874    appears in CM's autoload registry.  As a result, we see far fewer of
2875    those ?.Foo.Bar.xxx names in the prettyprinter's output.
2876    
2877    In addition to this I tried to clean up some pieces of the Basis
2878    implementation (e.g., Socket, Word8Array) in order to prevent other
2879    instances of these ?.Foo.Bar.xxx names from being printed.
2880    
2881    The mechanism that picks names for types still needs some work, though.
2882    (Right now it seems that if there is a type A.t which is defined to
2883    be B.u, but B is unavailable at toplevel, then A.t gets printed as
2884    "?.B.u" although the perhaps more sensible solution would be to use
2885    "A.t" in this case.  In other words, the prettyprinter should follow
2886    a chain of DEFtycs not farther than there are corresponding toplevel
2887    names in the current environment.)

2893    Description:
2894    
2895    Another installer tweak:  All the ML code for the installer is now
2896    compiled during CMB.make and put into a little library called
2897    $smlnj/installer.cm.  The installation then simply invokes
2898    
2899       sml -m $smlnj/installer.cm
2900    
2901    and everything happens automagically.
2902    
2903    Win32:  ML code senses value of environment variable SMLNJ_HOME.
2904    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
2905            and BINDIR.
2906    
2907    The new scheme guarantees that the ML code responsible for the installation
2908    is in sync with the APIs of the main system.  Also, the installer is
2909    somewhat faster because the installer script is precompiled.

2920    implementations of non-blocking operations from CML's Socket
2921    structure.

2926    Tag: blume-20030924-sockets
2927    Description:
2928    
2929    1. Fixed SOCKET API and implementation to match Basis spec.
2930       This required changing the internal representation of sockets to one
2931       that remembers (for each socket file descriptor) whether it is currently
2932       blocking or non-blocking.  This state is maintained lazily (i.e., a system
2933       call is made only if the state actually needs to change).
2934    
2935    2. OS-specific details of sockets were moved into separate files, thus
2936       making it possible to unify the bulk of the socket implementations
2937       between Unix and Win32.
2938    
2939    3. CML's socket API changed accordingly.
2940       (Note that we need to remove non-blocking functions from this API
2941       since they are redundant in the case of CML!)
2942    
2943    4. CML's socket implementation now makes use of non-blocking functions
2944       provided by Basis, thus removing all OS-dependent code from this part
2945       of CML.
2946    
2947    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

3060    Description:
3061    
3062    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3063    Modified config/install.bat to take advantage of it.  Also modified
3064    config/install.sh (and called it config/new-install.sh) to take advantage
3065    of it on Unix systems.  (The SML code is (supposed to be) platform-
3066    independent.)
3067    
3068    The installer can now install everything under Win32
3069    as well as under *nix as long as it compiles.
3070    
3071    Other changes:
3072    
3073      - made CML compile again under Win32
3074      - made eXene compile under Win32 (by providing a fake structure UnixSock
3075        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3076      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3077        same as type int;  under Win32 it isn't
3078      - fixed some slice-related problems in the win32-specific parts of CML
3079      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3080        (under Win32, the volume name is case-insensitive, and the
3081        OS.Path code compares volume names for equality)

3088    
3089    Made Win32 version of OS.FileSys.fullPath return current directory
3090    when given an empty string.  This is what the spec says, and incidentally,
3091    CM depends on it.  (CM otherwise goes into an infinite loop in certain
3092    cases when presented with the name of a non-existing .cm file.)

3098    Description:
3099    
3100      1. Changed interface to vectors and arrays in Basis to match
3101         (draft) Basis spec.
3102      2. Added signatures and implementations of slices according to
3103         Basis spec.
3104      3. Edited source code throughout the system to make it compile again
3105         under 1. and 2.  (In some cases code had to be added to have it
3106         match the new signatures.)
3107      4. MLRISC should be backward-compatible: the copies of the originals
3108         of files that needed to change under 3. were retained, the .cm files
3109         check the compiler version number and use old versions when
3110         appropriate.
3111      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3112         dirstream -> string option (in accordance with Basis spec).
3113      6. When generating code that counts lines, ml-lex used function
3114         CharVector.foldli, taking advantage of its old interface.
3115         This has been replaced with the corresponding code from
3116         CharVectorSlice.  (html-lex must be re-lexed!)
3117      7. BitArray in smlnj-lib/Util has been extended/modified to match the
3118         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
3119      8. Removed temporary additions (fromInternal, toInternal) from the
3120         (now obsolete) IntInf in smlnj-lib/Util.
3121      9. Cleaned up structure Byte.
3122     10. Added localOffset, scan, and fromString to Date (according to spec).
3123         Cleaned/corrected implementation of Date.
3124         (Still need to check for correctness; implement better canonicalizeDate.)
3125     11. Added "scan" to signature IEEE_REAL.
3126     12. Some improvements to IntInf [in particular: efficiency-hack for
3127         mod and rem when second operand is 2 (for parity checks).]
3128     13. Changed representation of type Time.time, using a single IntInf.int
3129         value counting microseconds.  This considerably simplified the
3130         implementation of structure Time.  We now support negative time
3131         values; scan and fromString handle signs.
3132     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3133         ArraySlice).

3139    Description:
3140    
3141    This is a major update which comes with a version number bump
3142    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3143    and an implementation of IntInf in the Basis.
3144    
3145    There are a fairly large number of related changes and updates throughout
3146    the system:
3147    
3148    Basis:
3149            - Implemented IntInf.
3150            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3151            - Added some missing Real64 operations, most notably Real.toLargeInt.
3152            - Added FixedInt as a synonym for Int32.
3153    
3154    compiler:
3155            * Added support for a built-in intinf type.
3156              - literals
3157              - pattern matching
3158              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3159              - overloading on literals and operations
3160    
3161            This required adding a primitive type intinf, some additional
3162            primops, and implementations for several non-trivial intinf
3163            operations in Core.  (The intinf type is completely abstract
3164            to the compiler; all operations get delegated back to the Core.)
3165    
3166            * Intinf equality is handled by polyequal.  However, the compiler
3167            does not print its usual warning in this case (since polyequal
3168            is the right thing to do there).
3169    
3170            * Improved the organization of structure InlineT.
3171    
3172            * A word about conversion primops:
3173            If conversions involving intinf do not cancel out during
3174            CPS contract, then the compiler must insert calls to Core functions.
3175            Since all core access must be resolved already during the FLINT
3176            translate phase, it would be too late a the time of CPS contract
3177            to add new Core calls.  For this reason, conversion primops
3178            for intinf carry two arguments:  1. the numeric argument that
3179            they are supposed to convert, and 2. the Core function that
3180            can help with this conversion if necessary.  If CPS contract
3181            eliminates a primop, then the associated Core function becomes
3182            dead and goes away.  Intinf conversion primops that do not get
3183            eliminated by CPS contract get rewritten into calls of their
3184            core functions by a separate, new phase.
3185    
3186    interactive system:
3187            - Control.Print.intinfDepth controls max length of intinf constants
3188            being printed. (Analogous to Control.Print.stringDepth.)
3189            - Cleanup in printutil and pputil: got rid of unused stuff and
3190            duplicates; replaced some of the code with code that makes better
3191            use of library functionality.
3192    
3193    CM:
3194            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3195            are no longer silent.
3196    
3197    CKIT:
3198            Fixed mismatched uses of Int32 and LargeInt.  I always decided
3199            in favor of LargeInt -- which is now the same as IntInf.
3200            CKIT-knowledgable people should check whether this is what's
3201            intended and otherwise change things back to using Int32 or
3202            FixedInt.
3203    
3204    Throughout the code:
3205            Started using IntInf.int literals and built-in operations
3206            (e.g., comparison with 0) where this seems appropriate.

3214    
3215    Merging changes from the mcz-branch development branch into trunk.
3216    These changes involve replacement of the emulated old prettyprinter
3217    interface with direct use of the SML/NJ Lib PP library, and fixing
3218    of a couple of bugs (895, 1186) relating to error messages.  A new
3219    prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
3220    has been added.

3226    Description:
3227    
3228    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
3229    
3230        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3231    
3232    This patch restores SML/NJ's ability to run under win32.  There are a
3233    number of changes, including fixes for several bugs that had gone
3234    unnoticed until now:
3235    
3236      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3237        trying to run the win32 version from within cygwin.)
3238    
3239      - There are a number of simple .bat scripts that substitute for their
3240        corresponding Unix shell-scripts.  (See below.)
3241    
3242      - The internals of ml-build have been modified slightly.  The main
3243        difference is that instead of calling ".link-sml" (or link-sml.bat)
3244        using OS.Process.system, the ML process delegates this task back
3245        to the script.  Otherwise problems arise in mixed environments such
3246        as Cygwin where scripts look and work like Unix scripts, but
3247        where OS.Process.system cannot run them.
3248    
3249      - In CM, the srcpath pickler used native pathname syntax -- which
3250        is incorrect in the case of cross-compilation.  The new pickle format
3251        is independent of platform-specific naming conventions.
3252    
3253      - Path configuration files (such as lib/pathconfig) can now choose
3254        between native and standard syntax.  Placing a line of the form
3255    
3256            standard!
3257    
3258        into the file causes all subsequent paths to be interpreted using
3259        CM standard pathname syntax (= Unix conventions); a line
3260    
3261            native!
3262    
3263        switches back to native style.  This was needed so that
3264        path config files can be written portably, see src/system/pathconfig.
3265    
3266      - Runtime system:
3267    
3268          - win32-filesys.c:  get_file_time and set_file_time now
3269            access modification time, not creation time.
3270    
3271          - I/O code made aware of new array representation.
3272    
3273          - Bug fixes in X86.prim.masm.
3274    
3275       - src/system/makeml made aware of win32. (For use under cygwin
3276            and other Unix-environments for windows.)
3277    
3278       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3279         which caused BinIO.inputAll to fail consistently.
3280    
3281    .bat scripts:
3282    
3283       Windows .bat scripts assume that SMLNJ_HOME is defined.
3284    
3285       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
3286         applications (sml, ml-yacc, ml-lex).
3287       - ml-build.bat: analogous to ml-build.
3288       - config\install.bat:  Analogous to config/install.sh.  This requires
3289         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3290         (nmake etc. must be on the path, and vcvars32 must have been run.)
3291         Moreover, sources for ml-lex and ml-yacc need to exist under src,
3292         and the bootfile hierarchy must have been unpacked under
3293         sml.boot.x86-win32.
3294         The script is very primitive and does a poor job at error checking.
3295         It only installs the base system, ml-lex, and ml-yacc.  No other
3296         libraries are being installed (i.e., you get only those that
3297         are part of the compiler.)
3298       - link-sml.bat:  analogous to .link-sml, but not currently used
3299    
3300    Unrelated bug fixes:
3301    
3302      - ml-nlffigen now exports structures ST_* corresponding to incomplete
3303        types.
3304      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
3305        otherwise.)
