196    
197    - Aaron: fixed a number of bugs in ml-ulex.
198    - Matthias:
199       - added CM control "cm.force-tools"; this is false by default;
200         when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
201         will be forced to run regardless of whether or not their targets
202         are up-to-date
203       - changed installer code so that config/install.sh will re-build
204         heap images for all tools even if those heap images already existed

210    
211    After Aaron Turon's bug fix for ml-ulex (handling the ^ character
212    in legacy mode), re-ran the lexer generator on all lex input files
213    and committed the results.
214    
215    This should fix the problem with ckit and nlffi that was reported
216    by Vesa A. Norrman.

231    
232    3rd merge of base from primop-branch-3 into the trunk.
233    Additional bug fixes included:
234    
235     * Timer.cpu_timer, etc. type printing corrected (by making
236         Timer have opaque sig constraint in basis/Implementation/timer.sml)

243    Description:
244    
245    Fixed some bugs in new Div code in FLINT/trans/translate.sml.
246    
247    Also, changed the handling of "no core access":  When translate.sml
248    needs access to a core exception at a time when the core has not
249    been set up yet (this only happens when compiling system/smlnj/init/*),
250    then don't bother generating the corresponding tests.
251    
252    The old scheme was to generate a bogus value to be used in place of
253    the exception.  Unfortunately, that confuses the plambda type checker.
254    Moreover, it does not do any good, because at runtime we don't expect
255    such an exception to be ever raised.  (The code in system/smlnj/init/*
256    has to be written very carefully with this in mind!)

268    Description:
269    
270    FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
271    with an explicit test for zero division.  This should fixes several
272    regressions and makes it possible for downstream optimization phases
273    to treat these operations as "pure" when they are applied to unsigned
274    operands.

289    
290    A number of fixes related to the formatting of dates.  These include fixes
291    for bugs #1415 and #1416.  We also now correctly handle format characters that
292    lie outside the specified set.

295    Name: Matthias Blume (http://www.tti-c.org/blume/)
296    Date: 2007/05/23 22:30:00 CDT
297    Description:
298    
299    CMB (and CM) now automatically defines the CM "preprocessor" symbol
300    NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
301    
302      (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
303       CM_SLAVE_MODE is defined in attached slaves while running CM.make
304       or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
305       while running CMB.make.  The point is that the single symbol
306       NO_PLUGINS is definde in all three cases.)
307    
308    I changed the three locations within the sources that get compiled
309    during CMB.make where ml-yacc or ml-lex input is processed: When
310    NO_PLUGINS defined, then the use of the mlyacc and mllex tools
311    is bypassed.
312    
313    When bootstrapping new versions of the compiler, there can be
314    situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
315    are not available or otherwise not operational.  In this case one can
316    manually define the NO_PLUGINS symbol prior to running CMB.make().  To
317    do so, the following command should be issued at the interactive
318    prompt:
319    
320       #set (CMB.symval "NO_PLUGINS") (SOME 1);
321    
322    A CMB.make with NO_PLUGINS defined relies on the existence of the
323    files that normally would be generated by ml-yacc and ml-lex.
324    (Copies of these files are in the repository.)

340    Description:
341    
342    Changed the installation mechanism for CM tool plugins.  These are
343    just libaries and now get installed like ordinary libaries.
344    
345    There are now a number of new installation targets that give some
346    fine-grain control over what classes and suffixes are known, and what
347    they will map to.
348    See config/targets for details.
349    
350    The code that caused plugin installation as part of running a
351    tool's "build" script has been removed.  (The build script is for
352    building, not for installing.)

357    Description:
358    
359    Added a boolean control named cm.tolerate-tool-failures (env. variable
360    name: CM_TOLERATE_TOOL_FAILURES).  The default is false and makes
361    CM fail if a shell tool reports a non-success exit status.  If
362    the control is set to true, then CM will press on after tool failures
363    in the event that the target files exist (even though they are
364    considered outdated).  Turning the control to true can be useful for
365    bootstrapping.

370    Description:
371    
372    Merge of ml-lpt revisions for 110.64.
373    
374    The name of several ml-lpt-lib modules has changed:
375      Repair        => AntlrRepair
376      StreamPos     => AntlrStreamPos
377      ErrHandlerFn  => AntlrErrHandler
378      EBNF          => AntlrEBNF
379    
380    The ml-antlr specification format has changed: declarations such as
381    %tokens and nonterminal definitions can occur *multiple* times in the
382    same specification.  The semantics are such that each new declaration
383    extends the previous ones.  This does not apply to %start or %name,
384    of course.
385    
386    Importing a grammar via %import now includes *all* declarations in from
387    the imported grammar, except for %name, %entry, and %start.  Tokens
388    and nonterminals can be dropped using the new %dropping clause of the
389    %import directive; the separate %drop and %extend have been removed.
390    
391    We now allow optional type annotations on nonterminals, using the %nonterms
392    directive as in ml-yacc.
393    
394    The refcell construct is now implemented using SML's regular reference
395    cells, so the :== and !! notation has been deprecated.
396    
397    The ml-antlr tool now does much more checking of specifications, and
398    its error messages have been greatly improved.  Error repair for
399    generated parsers has been completely rewritten, and is now both
400    much faster and more accurate.
401    
402    ml-ulex is now more lenient with escape codes (non-SML-standard
403    escape codes are now interpreted literally, so e.g. \| denotes "|").
404    Also, character classes may now include a "-" character at the beginning
405    as is standard in most other regexp tools.
406    
407    All of these changes are documented in the user guide, which has
408    been updated and improved with this merge.

467    The ml-antlr tool now does much more checking of specifications, and
468    its error messages have been greatly improved.  There has also been
469    some work on the error repair process for generated parsers, but this
470    will be further improved in 110.64.

477    More Basis fixes: The Char.fromString (etc.) functions did not handle
478    the "\uxxxx" escape sequence.  There is still an outstanding bug with
479    String.fromString the tail is a format escape.  I added a comment to
480    this effect in Basis/Implementation/string.sml.

561    Added preliminary support in MLRISC for Staged Allocation, a technique
562    for specifying calling conventions (see
563    http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
564    Initially, we plan to use this code to generate C calls for the AMD64.
565    
566    The staged allocation code base resides in MLRISC/staged-allocation,
567    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

633    
634    Brought ml-lpt manual up-to-date with the code.  Many minor
635    improvements to the tools, and a few minor bugfixes.  Prepared
636    ml-lpt-lib for integration with new UTF8 structure.  Changed
637    the interface for creating streams in ml-ulex (we now support
638    stream creation from several kinds of sources).  Overall, the
639    tools are now quite stable, and their interfaces are unlikely to
640    change in a way that would break compatibility.  More work,
641    however, is needed in the documentation.

646    Description:
647    
648    Implemented library installer.  Moved CM plugin code for
649    ml-burg, ml-lex, and ml-yacc out of CM source tree and into
650    their respective trees.  Implemented CM plugin for ml-ulex
651    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
652    and ml-antlr.
653    
654    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
655    CM tools.  (It turns out to be too messy to do otherwise because
656    there is too much code that during installation relies on the presence
657    of these tools -- resulting in a tricky ordering problem.)

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

737    Description:
738    
739    Added code to CM's "standard shell tool" implementation which
740    causes it to tolerate (with a warning) the situation where the shell
741    command fails (e.g., due to the shell command's non-existence)
742    as long as all target files exist.
743    
744    This makes it possible to, e.g., build ml-yacc from sources even if
745    svn checkout messed up the time stamps on files in such a way that
746    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
747    be needed to re-process yacc.grm, but obviously it might not yet be
748    available at that time.)

788    Description:
789    
790    New working release (110.60).  NEW BOOTFILES!
791    
792    This is the first subversion-hosted release.  There are also changes
793    to the directory layout.  Here is a table:
794    
795    (All pathnames are relative to the SML/NJ "root" directory.)
796    
797      config -> config
798    
799      src/cm -> base/cm
800      src/compiler -> base/compiler
801      src/runtime -> base/runtime
802      src/system -> base/system
803    
804      src/cm/pgraph -> pgraph
805    
806      src/READMES -> base/READMES
807      src/$notefile -> base/NOTES/$notefile
808         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
809                           MACOSXINSTALL WININSTALL
810    
811      src/smlnj-lib -> smlnj-lib
812      src/MLRISC -> MLRISC
813      ckit -> ckit
814      src/cml -> cml
815      src/eXene -> eXene
816      src/heap2asm -> heap2asm
817      src/lexgen -> lexgen
818      src/ml-burg -> ml-burg
819      src/ml-lex -> ml-lex
820      src/ml-yacc -> ml-yacc
821      src/ml-nlffi-lib -> nlffi/lib
822      src/ml-nlffigen -> nlffi/gen
823      src/smlnj-c -> smlnj-c
824      src/tools/TraceDebugProf -> trace-debug-profile
825    
826    In addition, there is also a new
827    
828      ml-lpt
829    
830    directory containing two new program generator tools: ml-ulex and
831    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
832    LL(k) parser generator). These tools are currently "beta-quality"
833    
834    The latest versios of the sources can now be obtained anonymously
835    via subversion.  For this, it is useful to first check out
836    
837       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
838    
839    and put the resulting directory on your shell's PATH.  This provides
840    access to three shell scripts: checkout-all.sh, stat-all.sh,
841    and refresh-all.sh.
842    
843    To create a freshly checked-out copy of the sources, do
844    
845       checkout-all.sh [dir]
846    
847    where dir is the optional SML/NJ root directory (default is ".").
848    
849    This creates the above directory layout.  Each subdirectory of
850    the root is under individual subversion control.  The stat-all.sh
851    and refresh-al.sh scripts apply "svn stat" or "svn update" to
852    each of these subtrees.
853    
854    ----------------------------------------------------------------------
855    Name: Matthias Blume (http://www.tti-c.org/blume/)
856    Date: 2006/11/02 12:20:00 CST
857    Description:
858    
859    Reorganized directory layout.
860    
861    This is a temporary solution, more reorganization is to come.
862    
863    The basic idea is to have a number of toplevel trees, each corresponding
864    to a well-defined part of the overall system.  Each part can be
865    maintained individually, even in separate source repositories,
866    although currently we still serve everything out of the main
867    smlnj-gforge tree.
868    
869    Installer and and scripts have been updated to reflect the new
870    layout.  The installer (base/src/system/smlnj/installer) is now
871    "scriptable" to avoid burning too much knowledge about the
872    layout into SML source code.  The main script used by the installer
873    is in config/actions.
874    
875    The main change is that many of the subdirectories of what used to
876    be known as "src" have moved to the toplevel.  The "src" directory
877    itself has moved down into a subtree called "base".  (We may eventually
878    get rid of the extra level of indirection represented by "src".)
879    
880    The layout is now as follows:
881    
882      toplevel tree name | default repository
883                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
884      -------------------+----------------------------------------------------
885      config             | $gf/config/trunk
886                         |
887      base               | $gf/sml/trunk
888                         |
889      smlnj-lib          | $gf/smlnj-lib/trunk
890      MLRISC             | $gf/MLRISC/trunk
891                         |
892      ml-yacc            | $gf/ml-yacc/trunk
893      ml-lex             | $gf/ml-lex/trunk
894      ml-burg            | $gf/ml-burg/trunk
895      lexgen             | $gf/lexgen/trunk
896      heap2asm           | $gf/heap2asm/trunk
897                         |
898      cml                | $gf/cml/trunk
899      eXene              | $gf/eXene/trunk
900      ckit               | $gf/ckit/trunk
901      nlffi              | $gf/nlffi/trunk
902                         |
903      smlnj-c            | $gf/smlnj-c/trunk
904    
905    In $gf/admin there are a few useful shell scripts for checking out
906    and maintaining the entire collection of trees:
907    
908       admin/checkout-all.sh [dir]
909          -- optionally creates dir and checks out all trees from their
910             default repositories; if dir is missing, checkout into .
911       admin/refresh-all.sh [dir]
912          -- looks at all trees (from the above list) in dir (default: .)
913             and runs "svn update" if the tree exists and is under
914             subversion control;
915             non-existing or non-subversion trees are skipped
916       admin/stat-all.sh [dir]
917          -- like refresh-all.sh, but runs "svn stat" instead

932    Description:
933    
934    New working version (110.59).  NEW BOOTFILES!
935    
936    I am freezing 110.59.  Changes other than the version-number increase:
937    
938      eXene:
939    
940         * committed changes to eXene from Alley Stoughton:
941             "fixed bugs in X authorization and resource handling, as well
942              as in the pile and viewport widgets"
943    
944      Runtime:
945        * fixed linking problem with NetBSD 3.x.
946    
947      Lexgen:
948        * lexgen tool handles non-ascii characters in 7-bit mode the same
949          way that ml-lex does
950    
951        * lexgen propagates exceptions the same way that ml-lex does
952    
953      CML:
954        * Fixed a bug in the SyncVar polling functions (iGetPoll,
955          mTakePoll, and mGetPoll) that could lead to livelock.

961    Description:
962    
963    Implemented ml-makedepend (i.e., CM.sources) in a better (more robust)
964    way.  This should hopefully fix the ml-makedepend problem permanently.

970    Description:
971    
972    Fixed long-standing bug with ml-makedepend where it would output a
973    spurious dependency to a non-existing file.  (This is a simple fix.
974    It might need further looking into.)

1063    Description:
1064    
1065    Hooked code for Darwin-specific Intel ABI into main compiler.
1066    (This is a temporary solution which relies on the fact that the
1067    compiler itself does not use NLFFI.  Eventually we need to divorce
1068    intel mac from generic x86 unix code and make separate sets of binaries.)

1097    Description:
1098    
1099    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
1100    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
1101    at the time when config/preloads is processed, the library has to
1102    be referred to by another name.  In 110.57 this would be
1103    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
1104    to be valid as well.)
1105    
1106    Thanks to Todd Wilson (Fresno) for alerting me to this issue.

1124    the physical location of basis.cm has changed).  Also, corrected the
1125    path anchor for $/html-lib.cm.  (Thanks to M. Fluet for pointing out
1126    these problems.)

1159    Tag: blume-22051115-versiontool
1160    Description:
1161    
1162    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
1163    file gets loaded as a tool -- by the equivalent of CM.make during the
1164    run of CMB.make.  Thus, CMB's path configuration is meaningless for
1165    it.  Instead, it has the status of "user code", so it should use
1166    $/basis.cm to refer to the Basis library.  (At least that's true for
1167    the purpose of bootstrapping the previous change.  In the future it
1168    might make sense to have versiontool.cm refer to
1169    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1170    compiler itself uses.)
1171    
1172    Also patched src/system/testml to have it activate those extra anchor
1173    bindings in config/extrapathconfig.

1178    Tag: blume-22051115-libraries
1179    Description:
1180    
1181    This change affects the way the following libraries are tied into
1182    the system:
1183    
1184       $/basis.cm
1185       $/smlnj-lib.cm
1186       $/pp-lib.cm
1187       $/controls-lib.cm
1188       $/html-lib.cm
1189       $/ml-yacc-lib.cm
1190    
1191    These libraries are now internally (as seen from the source code
1192    of the implementation itself) known by the following names:
1193    
1194       $smlnj/basis/basis.cm
1195       $smlnj/smlnj-lib/smlnj-lib.cm
1196       $smlnj/smlnj-lib/pp-lib.cm
1197       $smlnj/smlnj-lib/controls-lib.cm
1198       $smlnj/smlnj-lib/html-lib.cm
1199       $smlnj/ml-yacc/ml-yacc-lib.cm
1200    
1201    This makes it possible to work with code that requires different
1202    versions of these libraries, and which refers to these libraries using
1203    their "default" names (i.e., the first set of names above).  In other
1204    words, one can un-define or re-define those default names without
1205    compromising the proper functioning of the compiler itself.
1206    
1207    A similar procedure had already been performed for several of the
1208    MLRISC libraries that are linked into the compiler.  I did some
1209    cleanup on this code.
1210    
1211    A new file in the config directory (named extrapathconfig) is
1212    responsible for setting up path anchors that the compiler itself does
1213    not need, but that are typically required by user code.

1392    Tag: blume-20050516-redump-heap
1393    Description:
1394    
1395    Added mechanism for re-creating a heap file for the interactive system
1396    after configuration variables have been changed.
1397    
1398       CM.redump_heap : string -> unit
1399    
1400    This is much like SMLofNJ.exportML, but starting from the resulting
1401    heap does not return to the caller of CM.redump_heap but
1402    restarts the interactive system from scratch.  The original call of
1403    CM.redump_heap does not return but ends the interactive session.
1404    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1405    
1406    Internally, redump_heap winds the dynamic execution context back to
1407    the point where the original heap image was created and re-executes
1408    the heap image generation code in the boot code.

1524    Tag: blume-20050114-heap2exec
1525    Description:
1526    
1527    Implemented new (but still experimental) heap2exec facility.  This is
1528    tested under Mac OS X and should work under Linux (will test shortly).
1529    It will probably also work on the Sparc (will test some time later).
1530    
1531      - removed old "HACKED_STANDALONE" hack from runtime
1532    
1533    To be able to test this, uncomment the request for "heap2asm" in
1534    config/targets prior to installation.  (Notice that this is different
1535    from "heap2exec" mentioned below.  Not a typo.)
1536    
1537    To perform an actual test, run the command
1538    
1539       $ bin/heap2exec heapfile execfile
1540    
1541    (You can put heap2exec on your shell's path.)
1542    
1543    For example, run
1544    
1545      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1546    
1547    This will create a standalone executable called "mly" which you can
1548    then invoke directly as a command.

1693    Tag: blume-20041124-position
1694    Description:
1695    
1696    The compiler can now be compiled in a mode that makes structure Position
1697    equal to Int64.  The default, however, is unchanged (Position = Int31)
1698    for the time being.
1699    
1700    To enable 64-bit positions, use the following procedure:
1701    
1702    1. Start sml
1703    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1704    3. Type
1705          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1706    4. Run CMB.make() as usual.
1707    
1708    This is barely tested.  The only test so far was a little SML program
1709    counting the number of characters in an 8-gigabyte file by
1710    reading it character-by-character.  That test was successful.
1711    
1712    In support of 64-bit positions, a number of new functions have been
1713    added to the runtime system.

1758    
1759    - In a previous commit, fixed a minor issue with how polyequal is being
1760      translated.  In particular, the code now "looks through" abstractions.
1761      This results in slightly fewer polyEqual warnings and hopefully slightly
1762      more efficient code.  Important examples for where this matters are
1763      the new int64 and word64 types.

1783    32-bit wide.)

1786    are still missing.

1792    Description:
1793    
1794    Structure Word64 is now (almost) complete, word literals and patterns
1795    seem to work.  There are a few odd pieces missing.  In particular,
1796    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1797    at the moment.
1798    
1799    Making Word64 official would mean that LargeWord becomes Word64.  But
1800    this requires extreme care because most word-word conversions have to
1801    go through LargeWord, so making a mistake means loss of efficiency or
1802    worse.  Eventually there will be a solution similar to (but actually
1803    simpler than) what I did with IntInf.

1828    
1829    New working version (110.50).  NEW BOOTFILES!
1830    
1831                 =====================
1832    
1833    Also:
1834    
1835      - Changend config/srcarchiveurl from a file just
1836        containing the URL string into a file containing
1837        shell script code.  The code has access to the $VERSION variable.
1838      - Made corresponding changes to config/install.sh and config/unpack.
1839      - Default contents of config/srcarchiveurl uses $VERSION and
1840        normally does not have to be edited to reflect a version change.
1841    
1842      (As a result, a version change can be done by just editing
1843       config/version, the rest is now automatic.)

1883    Tag: blume-20041020-standalone-backtrace
1884    Description:
1885    
1886    Added a mechanism for getting back-trace information from standalone
1887    programs.  Here is how it works:
1888    
1889       1. The part of the program from which you want to get backtrace
1890          information (usually the whole program) should be wrapped with
1891          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
1892          main program could be modified from something like
1893    
1894             fun main (pgm, args) = ...
1895    
1896         to
1897    
1898            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1899    
1900       2. To be able to access BackTrace.monitor, you have to add
1901          library $smlnj-tdp/plugins.cm to the .cm file that contains your
1902          main function.
1903    
1904       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1905          CM might have created in the past for your project).
1906    
1907       4. Build the system using this command line:
1908    
1909             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1910                      myprog.cm MyProg.main myprog
1911    
1912          instead of the usual
1913    
1914             ml-build myprog.cm MyProg.main myprog
1915    
1916    I changed a library name:
1917    
1918       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1919    
1920    New libraries:
1921    
1922       $smlnj-tdp/back-trace.cm
1923          -- when loaded causes the back-trace plugin to be installed
1924       $smlnj-tdp/coverage.cm
1925          -- when loaded causes the coverage plugin to be installed

1941    Description:
1942    
1943    * Test coverage tool added!
1944    * Further reorganization of tracing-, debugging-, and profiling support:
1945    
1946        - moved original BTImp -- now called BackTrace -- into a separate
1947          library called $/trace-debug-profile.cm
1948        - eliminated all mentions of BTrace from SMLofNJ.Internals
1949        - only the instrumentation mechanism is now left in the compiler proper
1950        - BackTrace module is a plugin which is NOT plugged in by default
1951        - Coverage module is another such plugin
1952    
1953    To get the benefits of any of these plugin modules, the code in
1954    question must be compiled with tdp instrumentation turned on.  This
1955    can be done by setting SMLofNJ.Internals.TDP.mode to true.
1956    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1957    
1958    Plugins are selected at link time.  (Pre-compiled instrumented code
1959    can be re-loaded with different plugins in effect.)  When an
1960    instrumented module is linked, whatever plugins are at that time
1961    enabled will come into effect for that module.
1962    
1963    To enable the back-trace plugin, load library $/trace-debug-profile.cm
1964    and invoke BackTrace.install() (e.g., from the interactive prompt).
1965    To enable the coverage plugin, load the same library and invoke
1966    Coverage.install().
1967    
1968    Back-traces are generated automatically on uncaught exceptions and
1969    when the code in question explicitly invokes BackTrace.trigger().
1970    
1971    Coverage (and execution frequency-) information must be queried
1972    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

1989    Some rationalization of names:

1994    This is is preparation of using the original back-trace
1995    instrumentation for other purposes.  "TDP" stands for
1996    Trace/Debug/Profile.
1997    
1998    The control flag controlling whether instrumentation is on or off is now
1999    registered under a different name, so instead of running sml as
2000    
2001     sml -Cinstrument.btrace-mode=true
2002    
2003    one has to say

2021    Description:
2022

2024    treats subsequent occurrences of "group", "library", "source", "is",
2025    "*", and "-" as ordinary identifiers rather than keywords.
2026    
2027    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
2028    is supposed to accept a tool argument called "source", but this did
2029    not work because of the clash with the keyword.

2072    Description:
2073    
2074    * Moved the "version" magic into its own little library under
2075      src/system/smlnj/internal.  This avoids expensive reconstruction of
2076      a stable src/compiler/core.cm.
2077    
2078    * At the same time, structure CompilerVersion is now known as
2079      structure SMLNJVersion.
2080    
2081    * Arranged for the version tool to NOT kick in when rebuilding the system
2082      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
2083      Also, loading the versiontool does not work when rebuilding the system
2084      because CM is not properly initialized at that time.

2089    Tag: blume-20040929-autoversion
2090    Description:
2091    
2092    Implemented some CM magic to have
2093        file src/compiler/TopLevel/main/version.sml
2094    generated automagically.
2095    The version is taken from two files: config/version and config/release.
2096    The first is expected to contain a two-part version number such as 110.49.
2097    The second should contain a single number, but it may be missing.
2098    
2099    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2100    time the version tool is loaded (which is the first time you say CMB.make),
2101    then the tool will increment the value stored in config/release every
2102    time CMB.make is invoked.
2103    
2104    The binfile format is now insensitive to anything beyond the first
2105    two components of a version number, so bumping the release does not render
2106    binfiles incompatible.  Auto-bumping can be used to keep track of versions
2107    during development without invalidating existing binfiles.
2108    
2109    In any case, every CMB.make updates the date information in version.sml.
2110    (This is the date that is printed in the banner.)

2123    Tag: blume-20040927-controls
2124    Description:
2125    
2126    Added two pieces of functionality to the Controls interface:
2127    
2128    1.   val save'restore: 'a control -> unit -> unit
2129    
2130       grabs the current value of the control in stage 1 and restores it
2131       in stage 2.
2132    
2133    2.   val set' : 'a control * 'a -> unit -> unit
2134    
2135       stores the given value into the control in stage 2 (i.e., delayed)
2136       but does all error checking in stage 1.
2137       (This is for string controls that need to do parse their argument --
2138        something that might fail.  In some cases, notably in CM, one
2139        already knows the intended argument but wants to delay the actual
2140        assignment until a time when error recovery would be more difficult.)
2141    
2142    Changed the handling of controls in tool arguments to classes "sml" and
2143    "lazysml":
2144       - use Controls.save'restore as a more robust way of restoring the
2145         old value (in particular: without having to re-parse the string)
2146       - use controls to handle the "overload" keyword in the init group
2147         (I believe this change actually fixes a long-standing obscure bug.)

2152    Tag: blume-20040927-lazysml
2153    Description:
2154    
2155    Added a new tool class called "lazysml" to CM's tool chest.  The only
2156    difference to "sml" is that compilation is done with Control.lazysml
2157    set to true.  A source of class "lazysml" is automatically recognized
2158    by a file name suffix of ".lml".
2159    
2160    In addition to the above feature, the original class "sml" now also
2161    supports a tool argument "lazy" which has the same effect.  As a
2162    result, the following three lines are equivalent:
2163    
2164        foo.sml : lazysml
2165        foo.sml : sml (lazy)
2166        foo.sml (lazy)
2167    
2168    The setting goes into effect both during parsing and during
2169    compilation.  The original setting is restored right after parsing and
2170    after compilation, respectively.
2171    
2172    In addition to all the above, there is also a general mechanism to set
2173    ANY of the "controls" that are available at the command line via
2174    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
2175    apply as well. (In fact, "lazy" is implemented as a special case of
2176    the general mechanism.)
2177    
2178    The .cm file syntax uses a new keyword tool argument called "with".
2179    There are several ways of indicating the desired settings:
2180    
2181        foo.sml (with:parser.quotations=true)
2182        foo.sml (with:(name:parser.quotations value:true))
2183        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2184        foo.sml (with:(name1=value1 name2=value2 ...))
2185        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2186    
2187        etc.
2188    
2189    Another possible abbreviation is to leave out the =v or value:v part
2190    if the name refers to a boolean control (in which case the value is
2191    taken to be true).  Thus, one could get lazy sml also by saying:
2192    
2193        foo.sml (with:parser.lazy-keyword=true)
2194        foo.sml (with:parser.lazy-keyword)
2195        foo.sml (with:(name:parser.lazy-keyword value:true))
2196        foo.sml (with:(name:parser.lazy-keyword))

2499    - added option (default: on) for passing the name of the SML/NJ's "bin"

2501    
2502         make <options> SMLNJ_BINDIR=<dir> <target>

2548    Description:
2549    
2550    Changed the interface of structures Timer and Unix to match the most
2551    recent Basis spec.
2552    
2553    In the case of Unix there still seems to be an open/weird issue:
2554    
2555       The {text,bin}{In,Out}streamOf functions are supposed to create
2556       fresh streams whenever they are called -- as opposed to have them
2557       return the same stream every time.  This design is supposed to
2558       prevent space leaks caused by proc values hanging on to streams.
2559    
2560       The reap function, on the other hand, is supposed to close the
2561       streams.  This cannot be done without having a handle on the
2562       stream in proc after all...
2563    
2564    I took the liberty to implement the following stopgap solution:
2565    
2566      The proc value hangs on to the most recently created stream(s).
2567      Reap closes those.  If either or both of the two streams hadn't
2568      been created at all yet, then reap will close the corresponding
2569      file descriptors directly.
2570    
2571    PS: I don't understand the original space leak argument anymore.  If
2572    a proc hangs on to the imperative stream, then I/O operations on those
2573    will advance the state of the cached stream and avoid the space leak.

2587    Description:
2588    
2589    CM now ignores (but still accepts) the "owner" information in group
2590    descriptions.  The owner of a group is its next enclosing
2591    library. Each group must have a unique owner.  (There is a virtual
2592    "toplevel" library that owns groups which are not nested within a real
2593    library.)  Previously, each group had to explicitly declare its owner,
2594    and CM would check that such a declaration is correct.  The new scheme
2595    is to have CM check that for each group there is precisely one owning
2596    library.
2597    
2598    The advantage of the new scheme is that the programmer no longer needs
2599    to maintain the somewhat annoying owner information.  The downside is
2600    that CM cannot enforce the ownership rule across multiple runs of
2601    CM.make.  Fortunately, enclosing the same group in two different
2602    libraries A and B which are not part of the same program does not
2603    cause real problems.

2622    Description:
2623    
2624    Arranged for ml-build to clean up after itself a little bit better.
2625    The script generates a temporary SML source file and compiles it using
2626    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
2627    gets rid of those at the end, so they don't accumulate under .cm.
2628    
2629    This required a minor change to install.sh because the name of the
2630    metadata directory (default: .cm) is actually configurable at
2631    installation time.

2663    2) "cd" into "src/runtime" in the source tree of a fresh
2664       110.45 installation.
2665    3) patch -p 1 < [your/path/to]runtime.diff
2666    
2667    The code compiles fine but has NOT yet been extensively tested.
2668    I only ran a few tests for basic socket client functionality
2669    (which worked fine).  Especially the functions that use ioctl
2670    are not tested at all and might not work (see below).
2671    
2672    I implemented this since we want to move to a newer version of sml/nj
2673    but need socket support in order to use it.  This is the first time I
2674    even had a look at the sml/nj source,  so please review my changes
2675    before making this part of the distribution!  Here are a few issues
2676    that I think might be better for someone to solve who is more
2677    familiar with the sml/nj source (and socket programming):
2678    
2679    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2680      exception since I could not figure out what the windows equivalent
2681      of these functions is
2682    
2683    - In sockets-osdep.h there are a some #include statements that are
2684      only used in a few files that include sockets-osdep.h
2685    
2686    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2687      does not process its return value since I don't know how to
2688      report an error upwards.
2689    
2690    - It would probably be good to have a call to WSACleanup() when
2691      the library is unloaded (if there is such a possibility).
2692      Otherwise I think Windows will take care of this automatically
2693      when the process finishes.
2694    
2695    - I used ioctlsocket() as a replacement for ioctl() but I have
2696      no idea if that is actually the proper replacement on Windows.
2697    
2698    - All these issues are marked in the code by "FIXME" comments.
2699    
2700    We use sml/nj extensively in our products and are quite happy
2701    with it.  I hope this contribution will help you.
2702    
2703    Keep up the good work!

2740    The installer now honors the "src-smlnj" target again, although its meaning

2743    in the "targets" file, then the installer will pull in sources for
2744    everything.  (Notice that this refers to source code only.  Compiled
2745    code is still only installed for modules that were requested explicitly
2746    or which are required for other modules that were requested explicitly.)

2780    Description:
2781    
2782    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
2783    of SML/NJ.  The problem is that
2784    
2785       lib = dlopen(NULL, ...)
2786       f   = dlsym(lib, "malloc");
2787    
2788    does not work on Windows unless we explicitly export symbols
2789    such as 'malloc' during linking.  We fixed this by explicitly
2790    exporting the required symbols with the magic gcc incantation:
2791    
2792        -Wl,--export-all cygwin.def
2793    
2794    where cygwin.def is a file containing all the symbols that
2795    we wish to export.
2796    
2797    I suspect this is a Windows problem and we'll have to
2798    do the same (somehow with windows compilers) when
2799    we build the native win32 version with the system
2800    calls LoadLibrary/GetProcAddress.

2873    lib during installation.  I originally implemented this directive as a

2875    Now that things have been stable for a long time and going back to the
2876    old CM is not an option, there is no reason to keep it around.)

2926    Description:
2927    
2928    I modified the read-eval-print loop so that the autoloader gets
2929    invoked whenever the prettyprinter tries to look up a symbol that
2930    is not currently defined in the toplevel environment but which
2931    appears in CM's autoload registry.  As a result, we see far fewer of
2932    those ?.Foo.Bar.xxx names in the prettyprinter's output.
2933    
2934    In addition to this I tried to clean up some pieces of the Basis
2935    implementation (e.g., Socket, Word8Array) in order to prevent other
2936    instances of these ?.Foo.Bar.xxx names from being printed.
2937    
2938    The mechanism that picks names for types still needs some work, though.
2939    (Right now it seems that if there is a type A.t which is defined to
2940    be B.u, but B is unavailable at toplevel, then A.t gets printed as
2941    "?.B.u" although the perhaps more sensible solution would be to use
2942    "A.t" in this case.  In other words, the prettyprinter should follow
2943    a chain of DEFtycs not farther than there are corresponding toplevel
2944    names in the current environment.)

2950    Description:
2951    
2952    Another installer tweak:  All the ML code for the installer is now
2953    compiled during CMB.make and put into a little library called
2954    $smlnj/installer.cm.  The installation then simply invokes
2955    
2956       sml -m $smlnj/installer.cm
2957    
2958    and everything happens automagically.
2959    
2960    Win32:  ML code senses value of environment variable SMLNJ_HOME.
2961    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
2962            and BINDIR.
2963    
2964    The new scheme guarantees that the ML code responsible for the installation
2965    is in sync with the APIs of the main system.  Also, the installer is
2966    somewhat faster because the installer script is precompiled.

2983    Tag: blume-20030924-sockets
2984    Description:
2985    
2986    1. Fixed SOCKET API and implementation to match Basis spec.
2987       This required changing the internal representation of sockets to one
2988       that remembers (for each socket file descriptor) whether it is currently
2989       blocking or non-blocking.  This state is maintained lazily (i.e., a system
2990       call is made only if the state actually needs to change).
2991    
2992    2. OS-specific details of sockets were moved into separate files, thus
2993       making it possible to unify the bulk of the socket implementations
2994       between Unix and Win32.
2995    
2996    3. CML's socket API changed accordingly.
2997       (Note that we need to remove non-blocking functions from this API
2998       since they are redundant in the case of CML!)
2999    
3000    4. CML's socket implementation now makes use of non-blocking functions
3001       provided by Basis, thus removing all OS-dependent code from this part
3002       of CML.
3003    
3004    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

3090    need ml-lex or ml-yacc won't compile the first time the installer
3091    runs).

3117    Description:
3118    
3119    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3120    Modified config/install.bat to take advantage of it.  Also modified
3121    config/install.sh (and called it config/new-install.sh) to take advantage
3122    of it on Unix systems.  (The SML code is (supposed to be) platform-
3123    independent.)
3124    
3125    The installer can now install everything under Win32
3126    as well as under *nix as long as it compiles.
3127    
3128    Other changes:
3129    
3130      - made CML compile again under Win32
3131      - made eXene compile under Win32 (by providing a fake structure UnixSock
3132        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3133      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3134        same as type int;  under Win32 it isn't
3135      - fixed some slice-related problems in the win32-specific parts of CML
3136      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3137        (under Win32, the volume name is case-insensitive, and the
3138        OS.Path code compares volume names for equality)

3145    
3146    Made Win32 version of OS.FileSys.fullPath return current directory
3147    when given an empty string.  This is what the spec says, and incidentally,
3148    CM depends on it.  (CM otherwise goes into an infinite loop in certain
3149    cases when presented with the name of a non-existing .cm file.)

3155    Description:
3156    
3157      1. Changed interface to vectors and arrays in Basis to match
3158         (draft) Basis spec.
3159      2. Added signatures and implementations of slices according to
3160         Basis spec.
3161      3. Edited source code throughout the system to make it compile again
3162         under 1. and 2.  (In some cases code had to be added to have it
3163         match the new signatures.)
3164      4. MLRISC should be backward-compatible: the copies of the originals
3165         of files that needed to change under 3. were retained, the .cm files
3166         check the compiler version number and use old versions when
3167         appropriate.
3168      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3169         dirstream -> string option (in accordance with Basis spec).
3170      6. When generating code that counts lines, ml-lex used function
3171         CharVector.foldli, taking advantage of its old interface.
3172         This has been replaced with the corresponding code from
3173         CharVectorSlice.  (html-lex must be re-lexed!)
3174      7. BitArray in smlnj-lib/Util has been extended/modified to match the
3175         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
3176      8. Removed temporary additions (fromInternal, toInternal) from the
3177         (now obsolete) IntInf in smlnj-lib/Util.
3178      9. Cleaned up structure Byte.
3179     10. Added localOffset, scan, and fromString to Date (according to spec).
3180         Cleaned/corrected implementation of Date.
3181         (Still need to check for correctness; implement better canonicalizeDate.)
3182     11. Added "scan" to signature IEEE_REAL.
3183     12. Some improvements to IntInf [in particular: efficiency-hack for
3184         mod and rem when second operand is 2 (for parity checks).]
3185     13. Changed representation of type Time.time, using a single IntInf.int
3186         value counting microseconds.  This considerably simplified the
3187         implementation of structure Time.  We now support negative time
3188         values; scan and fromString handle signs.
3189     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3190         ArraySlice).

3196    Description:
3197    
3198    This is a major update which comes with a version number bump
3199    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3200    and an implementation of IntInf in the Basis.
3201    
3202    There are a fairly large number of related changes and updates throughout
3203    the system:
3204    
3205    Basis:
3206            - Implemented IntInf.
3207            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3208            - Added some missing Real64 operations, most notably Real.toLargeInt.
3209            - Added FixedInt as a synonym for Int32.
3210    
3211    compiler:
3212            * Added support for a built-in intinf type.
3213              - literals
3214              - pattern matching
3215              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3216              - overloading on literals and operations
3217    
3218            This required adding a primitive type intinf, some additional
3219            primops, and implementations for several non-trivial intinf
3220            operations in Core.  (The intinf type is completely abstract
3221            to the compiler; all operations get delegated back to the Core.)
3222    
3223            * Intinf equality is handled by polyequal.  However, the compiler
3224            does not print its usual warning in this case (since polyequal
3225            is the right thing to do there).
3226    
3227            * Improved the organization of structure InlineT.
3228    
3229            * A word about conversion primops:
3230            If conversions involving intinf do not cancel out during
3231            CPS contract, then the compiler must insert calls to Core functions.
3232            Since all core access must be resolved already during the FLINT
3233            translate phase, it would be too late a the time of CPS contract
3234            to add new Core calls.  For this reason, conversion primops
3235            for intinf carry two arguments:  1. the numeric argument that
3236            they are supposed to convert, and 2. the Core function that
3237            can help with this conversion if necessary.  If CPS contract
3238            eliminates a primop, then the associated Core function becomes
3239            dead and goes away.  Intinf conversion primops that do not get
3240            eliminated by CPS contract get rewritten into calls of their
3241            core functions by a separate, new phase.
3242    
3243    interactive system:
3244            - Control.Print.intinfDepth controls max length of intinf constants
3245            being printed. (Analogous to Control.Print.stringDepth.)
3246            - Cleanup in printutil and pputil: got rid of unused stuff and
3247            duplicates; replaced some of the code with code that makes better
3248            use of library functionality.
3249    
3250    CM:
3251            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3252            are no longer silent.
3253    
3254    CKIT:
3255            Fixed mismatched uses of Int32 and LargeInt.  I always decided
3256            in favor of LargeInt -- which is now the same as IntInf.
3257            CKIT-knowledgable people should check whether this is what's
3258            intended and otherwise change things back to using Int32 or
3259            FixedInt.
3260    
3261    Throughout the code:
3262            Started using IntInf.int literals and built-in operations
3263            (e.g., comparison with 0) where this seems appropriate.

3271    
3272    Merging changes from the mcz-branch development branch into trunk.
3273    These changes involve replacement of the emulated old prettyprinter
3274    interface with direct use of the SML/NJ Lib PP library, and fixing
3275    of a couple of bugs (895, 1186) relating to error messages.  A new
3276    prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
3277    has been added.

3284    
3285    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
3286    
3287        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3288    
3289    This patch restores SML/NJ's ability to run under win32.  There are a
3290    number of changes, including fixes for several bugs that had gone
3291    unnoticed until now:
3292    
3293      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3294        trying to run the win32 version from within cygwin.)
3295    
3296      - There are a number of simple .bat scripts that substitute for their
3297        corresponding Unix shell-scripts.  (See below.)
3298    
3299      - The internals of ml-build have been modified slightly.  The main
3300        difference is that instead of calling ".link-sml" (or link-sml.bat)
3301        using OS.Process.system, the ML process delegates this task back
3302        to the script.  Otherwise problems arise in mixed environments such
3303        as Cygwin where scripts look and work like Unix scripts, but
3304        where OS.Process.system cannot run them.
3305    
3306      - In CM, the srcpath pickler used native pathname syntax -- which
3307        is incorrect in the case of cross-compilation.  The new pickle format
3308        is independent of platform-specific naming conventions.
3309    
3310      - Path configuration files (such as lib/pathconfig) can now choose
3311        between native and standard syntax.  Placing a line of the form
3312    
3313            standard!
3314    
3315        into the file causes all subsequent paths to be interpreted using
3316        CM standard pathname syntax (= Unix conventions); a line
3317    
3318            native!
