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

142    After Aaron Turon's bug fix for ml-ulex (handling the ^ character
143    in legacy mode), re-ran the lexer generator on all lex input files
144    and committed the results.
145

161    Description:
162    
163    3rd merge of base from primop-branch-3 into the trunk.
164    Additional bug fixes included:
165    
166     * Timer.cpu_timer, etc. type printing corrected (by making
167         Timer have opaque sig constraint in basis/Implementation/timer.sml)
168     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
169         Stefan Monnier)

173    Date: 2007/05/31 11:40:00 CDT
174    Description:
175    
176    Fixed some bugs in new Div code in FLINT/trans/translate.sml.
177    
178    Also, changed the handling of "no core access":  When translate.sml
179    needs access to a core exception at a time when the core has not
180    been set up yet (this only happens when compiling system/smlnj/init/*),
181    then don't bother generating the corresponding tests.
182    
183    The old scheme was to generate a bogus value to be used in place of
184    the exception.  Unfortunately, that confuses the plambda type checker.
185    Moreover, it does not do any good, because at runtime we don't expect
186    such an exception to be ever raised.  (The code in system/smlnj/init/*
187    has to be written very carefully with this in mind!)

200    
201    FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
202    with an explicit test for zero division.  This should fixes several
203    regressions and makes it possible for downstream optimization phases
204    to treat these operations as "pure" when they are applied to unsigned
205    operands.

212    Added the new MLRISC code generator for the AMD64.  This version,
213    in contrast to the previous one, uses SSE registers and instructions

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

227    Date: 2007/05/23 22:30:00 CDT
228    Description:
229    
230    CMB (and CM) now automatically defines the CM "preprocessor" symbol
231    NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
232    
233      (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
234       CM_SLAVE_MODE is defined in attached slaves while running CM.make
235       or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
236       while running CMB.make.  The point is that the single symbol
237       NO_PLUGINS is definde in all three cases.)
238    
239    I changed the three locations within the sources that get compiled
240    during CMB.make where ml-yacc or ml-lex input is processed: When
241    NO_PLUGINS defined, then the use of the mlyacc and mllex tools
242    is bypassed.
243    
244    When bootstrapping new versions of the compiler, there can be
245    situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
246    are not available or otherwise not operational.  In this case one can
247    manually define the NO_PLUGINS symbol prior to running CMB.make().  To
248    do so, the following command should be issued at the interactive
249    prompt:
250    
251       #set (CMB.symval "NO_PLUGINS") (SOME 1);
252    
253    A CMB.make with NO_PLUGINS defined relies on the existence of the
254    files that normally would be generated by ml-yacc and ml-lex.
255    (Copies of these files are in the repository.)

263    2nd merge of base from primop-branch-3 into the trunk.

265     Date.scan and Date.fromString fixed;
266     Overloading resolution fixed and some type printing problems corrected.

271    Description:
272    
273    Changed the installation mechanism for CM tool plugins.  These are
274    just libaries and now get installed like ordinary libaries.
275    
276    There are now a number of new installation targets that give some
277    fine-grain control over what classes and suffixes are known, and what
278    they will map to.
279    See config/targets for details.
280    
281    The code that caused plugin installation as part of running a
282    tool's "build" script has been removed.  (The build script is for
283    building, not for installing.)

287    Date: 2007/05/22 11:50:00 CDT
288    Description:
289    
290    Added a boolean control named cm.tolerate-tool-failures (env. variable
291    name: CM_TOLERATE_TOOL_FAILURES).  The default is false and makes
292    CM fail if a shell tool reports a non-success exit status.  If
293    the control is set to true, then CM will press on after tool failures
294    in the event that the target files exist (even though they are
295    considered outdated).  Turning the control to true can be useful for
296    bootstrapping.

301    Description:
302    
303    Merge of ml-lpt revisions for 110.64.
304    
305    The name of several ml-lpt-lib modules has changed:
306      Repair        => AntlrRepair
307      StreamPos     => AntlrStreamPos
308      ErrHandlerFn  => AntlrErrHandler
309      EBNF          => AntlrEBNF
310    
311    The ml-antlr specification format has changed: declarations such as
312    %tokens and nonterminal definitions can occur *multiple* times in the
313    same specification.  The semantics are such that each new declaration
314    extends the previous ones.  This does not apply to %start or %name,
315    of course.
316    
317    Importing a grammar via %import now includes *all* declarations in from
318    the imported grammar, except for %name, %entry, and %start.  Tokens
319    and nonterminals can be dropped using the new %dropping clause of the
320    %import directive; the separate %drop and %extend have been removed.
321    
322    We now allow optional type annotations on nonterminals, using the %nonterms
323    directive as in ml-yacc.
324    
325    The refcell construct is now implemented using SML's regular reference
326    cells, so the :== and !! notation has been deprecated.
327    
328    The ml-antlr tool now does much more checking of specifications, and
329    its error messages have been greatly improved.  Error repair for
330    generated parsers has been completely rewritten, and is now both
331    much faster and more accurate.
332    
333    ml-ulex is now more lenient with escape codes (non-SML-standard
334    escape codes are now interpreted literally, so e.g. \| denotes "|").
335    Also, character classes may now include a "-" character at the beginning
336    as is standard in most other regexp tools.
337    
338    All of these changes are documented in the user guide, which has
339    been updated and improved with this merge.

490    Description:
491    
492    Added preliminary support in MLRISC for Staged Allocation, a technique
493    for specifying calling conventions (see
494    http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
495    Initially, we plan to use this code to generate C calls for the AMD64.
496    
497    The staged allocation code base resides in MLRISC/staged-allocation,
498    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

563    Description:
564    
565    Brought ml-lpt manual up-to-date with the code.  Many minor
566    improvements to the tools, and a few minor bugfixes.  Prepared
567    ml-lpt-lib for integration with new UTF8 structure.  Changed
568    the interface for creating streams in ml-ulex (we now support
569    stream creation from several kinds of sources).  Overall, the
570    tools are now quite stable, and their interfaces are unlikely to
571    change in a way that would break compatibility.  More work,
572    however, is needed in the documentation.

577    Description:
578    
579    Implemented library installer.  Moved CM plugin code for
580    ml-burg, ml-lex, and ml-yacc out of CM source tree and into
581    their respective trees.  Implemented CM plugin for ml-ulex
582    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
583    and ml-antlr.
584    
585    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
586    CM tools.  (It turns out to be too messy to do otherwise because
587    there is too much code that during installation relies on the presence
588    of these tools -- resulting in a tricky ordering problem.)

593    Description:
594    
595    Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
596    Modified CM's startup code to use shiftArgs as it processes
597    command line arguments.  This way, the init code in each .sml-file
598    or library that is mentioned at the top level will see only
599    those arguments that have not yet been processed at this point.
600    In other words, the init code can "seize control" and process the
601    remaining command line.

667    Date: 2006/12/08 09:50:00 CST
668    Description:
669    
670    Added code to CM's "standard shell tool" implementation which
671    causes it to tolerate (with a warning) the situation where the shell
672    command fails (e.g., due to the shell command's non-existence)
673    as long as all target files exist.
674    
675    This makes it possible to, e.g., build ml-yacc from sources even if
676    svn checkout messed up the time stamps on files in such a way that
677    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
678    be needed to re-process yacc.grm, but obviously it might not yet be
679    available at that time.)

719    Description:
720    
721    New working release (110.60).  NEW BOOTFILES!
722    
723    This is the first subversion-hosted release.  There are also changes
724    to the directory layout.  Here is a table:
725    
726    (All pathnames are relative to the SML/NJ "root" directory.)
727    
728      config -> config
729    
730      src/cm -> base/cm
731      src/compiler -> base/compiler
732      src/runtime -> base/runtime
733      src/system -> base/system
734    
735      src/cm/pgraph -> pgraph
736    
737      src/READMES -> base/READMES
738      src/$notefile -> base/NOTES/$notefile
739         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
740                           MACOSXINSTALL WININSTALL
741    
742      src/smlnj-lib -> smlnj-lib
743      src/MLRISC -> MLRISC
744      ckit -> ckit
745      src/cml -> cml
746      src/eXene -> eXene
747      src/heap2asm -> heap2asm
748      src/lexgen -> lexgen
749      src/ml-burg -> ml-burg
750      src/ml-lex -> ml-lex
751      src/ml-yacc -> ml-yacc
752      src/ml-nlffi-lib -> nlffi/lib
753      src/ml-nlffigen -> nlffi/gen
754      src/smlnj-c -> smlnj-c
755      src/tools/TraceDebugProf -> trace-debug-profile
756    
757    In addition, there is also a new
758    
759      ml-lpt
760    
761    directory containing two new program generator tools: ml-ulex and
762    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
763    LL(k) parser generator). These tools are currently "beta-quality"
764    
765    The latest versios of the sources can now be obtained anonymously
766    via subversion.  For this, it is useful to first check out
767    
768       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
769    
770    and put the resulting directory on your shell's PATH.  This provides
771    access to three shell scripts: checkout-all.sh, stat-all.sh,
772    and refresh-all.sh.
773    
774    To create a freshly checked-out copy of the sources, do
775    
776       checkout-all.sh [dir]
777    
778    where dir is the optional SML/NJ root directory (default is ".").
779    
780    This creates the above directory layout.  Each subdirectory of
781    the root is under individual subversion control.  The stat-all.sh
782    and refresh-al.sh scripts apply "svn stat" or "svn update" to
783    each of these subtrees.
784    
785    ----------------------------------------------------------------------
786    Name: Matthias Blume (http://www.tti-c.org/blume/)
787    Date: 2006/11/02 12:20:00 CST
788    Description:
789    
790    Reorganized directory layout.
791    
792    This is a temporary solution, more reorganization is to come.
793    
794    The basic idea is to have a number of toplevel trees, each corresponding
795    to a well-defined part of the overall system.  Each part can be
796    maintained individually, even in separate source repositories,
797    although currently we still serve everything out of the main
798    smlnj-gforge tree.
799    
800    Installer and and scripts have been updated to reflect the new
801    layout.  The installer (base/src/system/smlnj/installer) is now
802    "scriptable" to avoid burning too much knowledge about the
803    layout into SML source code.  The main script used by the installer
804    is in config/actions.
805    
806    The main change is that many of the subdirectories of what used to
807    be known as "src" have moved to the toplevel.  The "src" directory
808    itself has moved down into a subtree called "base".  (We may eventually
809    get rid of the extra level of indirection represented by "src".)
810    
811    The layout is now as follows:
812    
813      toplevel tree name | default repository
814                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
815      -------------------+----------------------------------------------------
816      config             | $gf/config/trunk
817                         |
818      base               | $gf/sml/trunk
819                         |
820      smlnj-lib          | $gf/smlnj-lib/trunk
821      MLRISC             | $gf/MLRISC/trunk
822                         |
823      ml-yacc            | $gf/ml-yacc/trunk
824      ml-lex             | $gf/ml-lex/trunk
825      ml-burg            | $gf/ml-burg/trunk
826      lexgen             | $gf/lexgen/trunk
827      heap2asm           | $gf/heap2asm/trunk
828                         |
829      cml                | $gf/cml/trunk
830      eXene              | $gf/eXene/trunk
831      ckit               | $gf/ckit/trunk
832      nlffi              | $gf/nlffi/trunk
833                         |
834      smlnj-c            | $gf/smlnj-c/trunk
835    
836    In $gf/admin there are a few useful shell scripts for checking out
837    and maintaining the entire collection of trees:
838    
839       admin/checkout-all.sh [dir]
840          -- optionally creates dir and checks out all trees from their
841             default repositories; if dir is missing, checkout into .
842       admin/refresh-all.sh [dir]
843          -- looks at all trees (from the above list) in dir (default: .)
844             and runs "svn update" if the tree exists and is under
845             subversion control;
846             non-existing or non-subversion trees are skipped
847       admin/stat-all.sh [dir]
848          -- like refresh-all.sh, but runs "svn stat" instead

873              as in the pile and viewport widgets"
874    
875      Runtime:
876        * fixed linking problem with NetBSD 3.x.
877    
878      Lexgen:
879        * lexgen tool handles non-ascii characters in 7-bit mode the same
880          way that ml-lex does
881    
882        * lexgen propagates exceptions the same way that ml-lex does
883    
884      CML:
885        * Fixed a bug in the SyncVar polling functions (iGetPoll,
886          mTakePoll, and mGetPoll) that could lead to livelock.

994    Description:
995    
996    Hooked code for Darwin-specific Intel ABI into main compiler.
997    (This is a temporary solution which relies on the fact that the
998    compiler itself does not use NLFFI.  Eventually we need to divorce
999    intel mac from generic x86 unix code and make separate sets of binaries.)

1028    Description:
1029    
1030    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
1031    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
1032    at the time when config/preloads is processed, the library has to
1033    be referred to by another name.  In 110.57 this would be
1034    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
1035    to be valid as well.)
1036    
1037    Thanks to Todd Wilson (Fresno) for alerting me to this issue.

1051    Description:
1052    
1053    Fixed a problem in config/install.sh where it tries to "fish" the
1054    name of the CM metadata directory from the wrong place (because
1055    the physical location of basis.cm has changed).  Also, corrected the
1056    path anchor for $/html-lib.cm.  (Thanks to M. Fluet for pointing out
1057    these problems.)

1090    Tag: blume-22051115-versiontool
1091    Description:
1092    
1093    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
1094    file gets loaded as a tool -- by the equivalent of CM.make during the
1095    run of CMB.make.  Thus, CMB's path configuration is meaningless for
1096    it.  Instead, it has the status of "user code", so it should use
1097    $/basis.cm to refer to the Basis library.  (At least that's true for
1098    the purpose of bootstrapping the previous change.  In the future it
1099    might make sense to have versiontool.cm refer to
1100    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1101    compiler itself uses.)
1102    
1103    Also patched src/system/testml to have it activate those extra anchor
1104    bindings in config/extrapathconfig.

1109    Tag: blume-22051115-libraries
1110    Description:
1111    
1112    This change affects the way the following libraries are tied into
1113    the system:
1114    
1115       $/basis.cm
1116       $/smlnj-lib.cm
1117       $/pp-lib.cm
1118       $/controls-lib.cm
1119       $/html-lib.cm
1120       $/ml-yacc-lib.cm
1121    
1122    These libraries are now internally (as seen from the source code
1123    of the implementation itself) known by the following names:
1124    
1125       $smlnj/basis/basis.cm
1126       $smlnj/smlnj-lib/smlnj-lib.cm
1127       $smlnj/smlnj-lib/pp-lib.cm
1128       $smlnj/smlnj-lib/controls-lib.cm
1129       $smlnj/smlnj-lib/html-lib.cm
1130       $smlnj/ml-yacc/ml-yacc-lib.cm
1131    
1132    This makes it possible to work with code that requires different
1133    versions of these libraries, and which refers to these libraries using
1134    their "default" names (i.e., the first set of names above).  In other
1135    words, one can un-define or re-define those default names without
1136    compromising the proper functioning of the compiler itself.
1137    
1138    A similar procedure had already been performed for several of the
1139    MLRISC libraries that are linked into the compiler.  I did some
1140    cleanup on this code.
1141    
1142    A new file in the config directory (named extrapathconfig) is
1143    responsible for setting up path anchors that the compiler itself does
1144    not need, but that are typically required by user code.

1323    Tag: blume-20050516-redump-heap
1324    Description:
1325    
1326    Added mechanism for re-creating a heap file for the interactive system
1327    after configuration variables have been changed.
1328    
1329       CM.redump_heap : string -> unit
1330    
1331    This is much like SMLofNJ.exportML, but starting from the resulting
1332    heap does not return to the caller of CM.redump_heap but
1333    restarts the interactive system from scratch.  The original call of
1334    CM.redump_heap does not return but ends the interactive session.
1335    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1336    
1337    Internally, redump_heap winds the dynamic execution context back to
1338    the point where the original heap image was created and re-executes
1339    the heap image generation code in the boot code.

1385    an mvar, leaving the door open for races.)

1455    Tag: blume-20050114-heap2exec
1456    Description:
1457    
1458    Implemented new (but still experimental) heap2exec facility.  This is
1459    tested under Mac OS X and should work under Linux (will test shortly).
1460    It will probably also work on the Sparc (will test some time later).
1461    
1462      - removed old "HACKED_STANDALONE" hack from runtime
1463    
1464    To be able to test this, uncomment the request for "heap2asm" in
1465    config/targets prior to installation.  (Notice that this is different
1466    from "heap2exec" mentioned below.  Not a typo.)
1467    
1468    To perform an actual test, run the command
1469    
1470       $ bin/heap2exec heapfile execfile
1471    
1472    (You can put heap2exec on your shell's path.)
1473    
1474    For example, run
1475    
1476      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1477    
1478    This will create a standalone executable called "mly" which you can
1479    then invoke directly as a command.

1624    Tag: blume-20041124-position
1625    Description:
1626    
1627    The compiler can now be compiled in a mode that makes structure Position
1628    equal to Int64.  The default, however, is unchanged (Position = Int31)
1629    for the time being.
1630    
1631    To enable 64-bit positions, use the following procedure:
1632    
1633    1. Start sml
1634    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1635    3. Type
1636          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1637    4. Run CMB.make() as usual.
1638    
1639    This is barely tested.  The only test so far was a little SML program
1640    counting the number of characters in an 8-gigabyte file by
1641    reading it character-by-character.  That test was successful.
1642    
1643    In support of 64-bit positions, a number of new functions have been
1644    added to the runtime system.

1689    
1690    - In a previous commit, fixed a minor issue with how polyequal is being
1691      translated.  In particular, the code now "looks through" abstractions.
1692      This results in slightly fewer polyEqual warnings and hopefully slightly
1693      more efficient code.  Important examples for where this matters are
1694      the new int64 and word64 types.

1711    All the pieces of Word64 are now there, with the exception of the
1712    conversions from and to LargeWord. (Eventually these need to be identities,
1713    but for the time being they don't even make sense because LargeWord is
1714    32-bit wide.)
1715    
1716    Also started to add similar support for Int64, but major pieces of that
1717    are still missing.

1723    Description:
1724    
1725    Structure Word64 is now (almost) complete, word literals and patterns
1726    seem to work.  There are a few odd pieces missing.  In particular,
1727    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1728    at the moment.
1729    
1730    Making Word64 official would mean that LargeWord becomes Word64.  But
1731    this requires extreme care because most word-word conversions have to
1732    go through LargeWord, so making a mistake means loss of efficiency or
1733    worse.  Eventually there will be a solution similar to (but actually
1734    simpler than) what I did with IntInf.

1767        containing the URL string into a file containing
1768        shell script code.  The code has access to the $VERSION variable.
1769      - Made corresponding changes to config/install.sh and config/unpack.
1770      - Default contents of config/srcarchiveurl uses $VERSION and
1771        normally does not have to be edited to reflect a version change.
1772    
1773      (As a result, a version change can be done by just editing
1774       config/version, the rest is now automatic.)

1814    Tag: blume-20041020-standalone-backtrace
1815    Description:
1816    
1817    Added a mechanism for getting back-trace information from standalone
1818    programs.  Here is how it works:
1819    
1820       1. The part of the program from which you want to get backtrace
1821          information (usually the whole program) should be wrapped with
1822          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
1823          main program could be modified from something like
1824    
1825             fun main (pgm, args) = ...
1826    
1827         to
1828    
1829            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1830    
1831       2. To be able to access BackTrace.monitor, you have to add
1832          library $smlnj-tdp/plugins.cm to the .cm file that contains your
1833          main function.
1834    
1835       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1836          CM might have created in the past for your project).
1837    
1838       4. Build the system using this command line:
1839    
1840             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1841                      myprog.cm MyProg.main myprog
1842    
1843          instead of the usual
1844    
1845             ml-build myprog.cm MyProg.main myprog
1846    
1847    I changed a library name:
1848    
1849       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1850    
1851    New libraries:
1852    
1853       $smlnj-tdp/back-trace.cm
1854          -- when loaded causes the back-trace plugin to be installed
1855       $smlnj-tdp/coverage.cm
1856          -- when loaded causes the coverage plugin to be installed

1872    Description:
1873    
1874    * Test coverage tool added!
1875    * Further reorganization of tracing-, debugging-, and profiling support:
1876    
1877        - moved original BTImp -- now called BackTrace -- into a separate
1878          library called $/trace-debug-profile.cm
1879        - eliminated all mentions of BTrace from SMLofNJ.Internals
1880        - only the instrumentation mechanism is now left in the compiler proper
1881        - BackTrace module is a plugin which is NOT plugged in by default
1882        - Coverage module is another such plugin
1883    
1884    To get the benefits of any of these plugin modules, the code in
1885    question must be compiled with tdp instrumentation turned on.  This
1886    can be done by setting SMLofNJ.Internals.TDP.mode to true.
1887    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1888    
1889    Plugins are selected at link time.  (Pre-compiled instrumented code
1890    can be re-loaded with different plugins in effect.)  When an
1891    instrumented module is linked, whatever plugins are at that time
1892    enabled will come into effect for that module.
1893    
1894    To enable the back-trace plugin, load library $/trace-debug-profile.cm
1895    and invoke BackTrace.install() (e.g., from the interactive prompt).
1896    To enable the coverage plugin, load the same library and invoke
1897    Coverage.install().
1898    
1899    Back-traces are generated automatically on uncaught exceptions and
1900    when the code in question explicitly invokes BackTrace.trigger().
1901    
1902    Coverage (and execution frequency-) information must be queried
1903    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

1919    
1920    Some rationalization of names:

1922       structure BTrace -> structure TDPInstrument
1923       etc.
1924    
1925    This is is preparation of using the original back-trace
1926    instrumentation for other purposes.  "TDP" stands for
1927    Trace/Debug/Profile.
1928    
1929    The control flag controlling whether instrumentation is on or off is now
1930    registered under a different name, so instead of running sml as
1931    
1932     sml -Cinstrument.btrace-mode=true
1933    
1934    one has to say
1935    
1936     sml -Ctdp.instrument=true

1952    Description:
1953    
1954    Fixed handling of keywords in .cm files: After seeing "is" the lexer
1955    treats subsequent occurrences of "group", "library", "source", "is",
1956    "*", and "-" as ordinary identifiers rather than keywords.
1957    
1958    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
1959    is supposed to accept a tool argument called "source", but this did
1960    not work because of the clash with the keyword.

2003    Description:
2004    
2005    * Moved the "version" magic into its own little library under
2006      src/system/smlnj/internal.  This avoids expensive reconstruction of
2007      a stable src/compiler/core.cm.
2008    
2009    * At the same time, structure CompilerVersion is now known as
2010      structure SMLNJVersion.
2011    
2012    * Arranged for the version tool to NOT kick in when rebuilding the system
2013      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
2014      Also, loading the versiontool does not work when rebuilding the system
2015      because CM is not properly initialized at that time.

2020    Tag: blume-20040929-autoversion
2021    Description:
2022    
2023    Implemented some CM magic to have
2024        file src/compiler/TopLevel/main/version.sml
2025    generated automagically.
2026    The version is taken from two files: config/version and config/release.
2027    The first is expected to contain a two-part version number such as 110.49.
2028    The second should contain a single number, but it may be missing.
2029    
2030    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2031    time the version tool is loaded (which is the first time you say CMB.make),
2032    then the tool will increment the value stored in config/release every
2033    time CMB.make is invoked.
2034    
2035    The binfile format is now insensitive to anything beyond the first
2036    two components of a version number, so bumping the release does not render
2037    binfiles incompatible.  Auto-bumping can be used to keep track of versions
2038    during development without invalidating existing binfiles.
2039    
2040    In any case, every CMB.make updates the date information in version.sml.
2041    (This is the date that is printed in the banner.)

2054    Tag: blume-20040927-controls
2055    Description:
2056    
2057    Added two pieces of functionality to the Controls interface:
2058    
2059    1.   val save'restore: 'a control -> unit -> unit
2060    
2061       grabs the current value of the control in stage 1 and restores it
2062       in stage 2.
2063    
2064    2.   val set' : 'a control * 'a -> unit -> unit
2065    
2066       stores the given value into the control in stage 2 (i.e., delayed)
2067       but does all error checking in stage 1.
2068       (This is for string controls that need to do parse their argument --
2069        something that might fail.  In some cases, notably in CM, one
2070        already knows the intended argument but wants to delay the actual
2071        assignment until a time when error recovery would be more difficult.)
2072    
2073    Changed the handling of controls in tool arguments to classes "sml" and
2074    "lazysml":
2075       - use Controls.save'restore as a more robust way of restoring the
2076         old value (in particular: without having to re-parse the string)
2077       - use controls to handle the "overload" keyword in the init group
2078         (I believe this change actually fixes a long-standing obscure bug.)

2083    Tag: blume-20040927-lazysml
2084    Description:
2085    
2086    Added a new tool class called "lazysml" to CM's tool chest.  The only
2087    difference to "sml" is that compilation is done with Control.lazysml
2088    set to true.  A source of class "lazysml" is automatically recognized
2089    by a file name suffix of ".lml".
2090    
2091    In addition to the above feature, the original class "sml" now also
2092    supports a tool argument "lazy" which has the same effect.  As a
2093    result, the following three lines are equivalent:
2094    
2095        foo.sml : lazysml
2096        foo.sml : sml (lazy)
2097        foo.sml (lazy)
2098    
2099    The setting goes into effect both during parsing and during
2100    compilation.  The original setting is restored right after parsing and
2101    after compilation, respectively.
2102    
2103    In addition to all the above, there is also a general mechanism to set
2104    ANY of the "controls" that are available at the command line via
2105    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
2106    apply as well. (In fact, "lazy" is implemented as a special case of
2107    the general mechanism.)
2108    
2109    The .cm file syntax uses a new keyword tool argument called "with".
2110    There are several ways of indicating the desired settings:
2111    
2112        foo.sml (with:parser.quotations=true)
2113        foo.sml (with:(name:parser.quotations value:true))
2114        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2115        foo.sml (with:(name1=value1 name2=value2 ...))
2116        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2117    
2118        etc.
2119    
2120    Another possible abbreviation is to leave out the =v or value:v part
2121    if the name refers to a boolean control (in which case the value is
2122    taken to be true).  Thus, one could get lazy sml also by saying:
2123    
2124        foo.sml (with:parser.lazy-keyword=true)
2125        foo.sml (with:parser.lazy-keyword)
2126        foo.sml (with:(name:parser.lazy-keyword value:true))
2127        foo.sml (with:(name:parser.lazy-keyword))

2479    Description:
2480    
2481    Changed the interface of structures Timer and Unix to match the most
2482    recent Basis spec.
2483    
2484    In the case of Unix there still seems to be an open/weird issue:
2485    
2486       The {text,bin}{In,Out}streamOf functions are supposed to create
2487       fresh streams whenever they are called -- as opposed to have them
2488       return the same stream every time.  This design is supposed to
2489       prevent space leaks caused by proc values hanging on to streams.
2490    
2491       The reap function, on the other hand, is supposed to close the
2492       streams.  This cannot be done without having a handle on the
2493       stream in proc after all...
2494    
2495    I took the liberty to implement the following stopgap solution:
2496    
2497      The proc value hangs on to the most recently created stream(s).
2498      Reap closes those.  If either or both of the two streams hadn't
2499      been created at all yet, then reap will close the corresponding
2500      file descriptors directly.
2501    
2502    PS: I don't understand the original space leak argument anymore.  If
2503    a proc hangs on to the imperative stream, then I/O operations on those
2504    will advance the state of the cached stream and avoid the space leak.

2518    Description:
2519    
2520    CM now ignores (but still accepts) the "owner" information in group
2521    descriptions.  The owner of a group is its next enclosing
2522    library. Each group must have a unique owner.  (There is a virtual
2523    "toplevel" library that owns groups which are not nested within a real
2524    library.)  Previously, each group had to explicitly declare its owner,
2525    and CM would check that such a declaration is correct.  The new scheme
2526    is to have CM check that for each group there is precisely one owning
2527    library.
2528    
2529    The advantage of the new scheme is that the programmer no longer needs
2530    to maintain the somewhat annoying owner information.  The downside is
2531    that CM cannot enforce the ownership rule across multiple runs of
2532    CM.make.  Fortunately, enclosing the same group in two different
2533    libraries A and B which are not part of the same program does not
2534    cause real problems.

2554    
2555    Arranged for ml-build to clean up after itself a little bit better.
2556    The script generates a temporary SML source file and compiles it using
2557    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
2558    gets rid of those at the end, so they don't accumulate under .cm.
2559    
2560    This required a minor change to install.sh because the name of the
2561    metadata directory (default: .cm) is actually configurable at
2562    installation time.

2577    Description:
2578    
2579    Added previously missing support for many socket-related functions
2580    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
2581    for the voluminous patch!
2582    
2583    (I have not tested this patch under win32 yet.)
2584    
2585    Here is David's e-mail:
2586    
2587    Hi,
2588    
2589    Attached to this email you find a diff against sml/nj 110.45
2590    that will enable socket support under Windows.
2591    
2592    To apply the patch (using unix or cygwin)
2593    1) gunzip runtime.diff.gz
2594    2) "cd" into "src/runtime" in the source tree of a fresh
2595       110.45 installation.
2596    3) patch -p 1 < [your/path/to]runtime.diff
2597    
2598    The code compiles fine but has NOT yet been extensively tested.
2599    I only ran a few tests for basic socket client functionality
2600    (which worked fine).  Especially the functions that use ioctl
2601    are not tested at all and might not work (see below).
2602    
2603    I implemented this since we want to move to a newer version of sml/nj
2604    but need socket support in order to use it.  This is the first time I
2605    even had a look at the sml/nj source,  so please review my changes
2606    before making this part of the distribution!  Here are a few issues
2607    that I think might be better for someone to solve who is more
2608    familiar with the sml/nj source (and socket programming):
2609    
2610    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2611      exception since I could not figure out what the windows equivalent
2612      of these functions is
2613    
2614    - In sockets-osdep.h there are a some #include statements that are
2615      only used in a few files that include sockets-osdep.h
2616    
2617    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2618      does not process its return value since I don't know how to
2619      report an error upwards.
2620    
2621    - It would probably be good to have a call to WSACleanup() when
2622      the library is unloaded (if there is such a possibility).
2623      Otherwise I think Windows will take care of this automatically
2624      when the process finishes.
2625    
2626    - I used ioctlsocket() as a replacement for ioctl() but I have
2627      no idea if that is actually the proper replacement on Windows.
2628    
2629    - All these issues are marked in the code by "FIXME" comments.
2630    
2631    We use sml/nj extensively in our products and are quite happy
2632    with it.  I hope this contribution will help you.
2633    
2634    Keep up the good work!
2635

2669    Description:
2670    
2671    The installer now honors the "src-smlnj" target again, although its meaning
2672    has changed from "all sources required for the compiler" to "all sources
2673    the installer knows about".  In other words, if you enable "src-smlnj"
2674    in the "targets" file, then the installer will pull in sources for
2675    everything.  (Notice that this refers to source code only.  Compiled
2676    code is still only installed for modules that were requested explicitly
2677    or which are required for other modules that were requested explicitly.)

2711    Description:
2712    
2713    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
2714    of SML/NJ.  The problem is that
2715    
2716       lib = dlopen(NULL, ...)
2717       f   = dlsym(lib, "malloc");
2718    
2719    does not work on Windows unless we explicitly export symbols
2720    such as 'malloc' during linking.  We fixed this by explicitly
2721    exporting the required symbols with the magic gcc incantation:
2722    
2723        -Wl,--export-all cygwin.def
2724    
2725    where cygwin.def is a file containing all the symbols that
2726    we wish to export.
2727    
2728    I suspect this is a Windows problem and we'll have to
2729    do the same (somehow with windows compilers) when
2730    we build the native win32 version with the system
2731    calls LoadLibrary/GetProcAddress.

2801    Eliminated the "dont_move_libraries" directive in config/targets.
2802    (The mechanism was broken and could not be fixed easily.  Moreover,
2803    there does not seem to be any reason not to move all libraries into
2804    lib during installation.  I originally implemented this directive as a
2805    backward-compatibility feature when I first introduced the new CM.
2806    Now that things have been stable for a long time and going back to the
2807    old CM is not an option, there is no reason to keep it around.)

2856    Tag: blume-20030926-ppautoload
2857    Description:
2858    
2859    I modified the read-eval-print loop so that the autoloader gets
2860    invoked whenever the prettyprinter tries to look up a symbol that
2861    is not currently defined in the toplevel environment but which
2862    appears in CM's autoload registry.  As a result, we see far fewer of
2863    those ?.Foo.Bar.xxx names in the prettyprinter's output.
2864    
2865    In addition to this I tried to clean up some pieces of the Basis
2866    implementation (e.g., Socket, Word8Array) in order to prevent other
2867    instances of these ?.Foo.Bar.xxx names from being printed.
2868    
2869    The mechanism that picks names for types still needs some work, though.
2870    (Right now it seems that if there is a type A.t which is defined to
2871    be B.u, but B is unavailable at toplevel, then A.t gets printed as
2872    "?.B.u" although the perhaps more sensible solution would be to use
2873    "A.t" in this case.  In other words, the prettyprinter should follow
2874    a chain of DEFtycs not farther than there are corresponding toplevel
2875    names in the current environment.)

2881    Description:
2882    
2883    Another installer tweak:  All the ML code for the installer is now
2884    compiled during CMB.make and put into a little library called
2885    $smlnj/installer.cm.  The installation then simply invokes
2886    
2887       sml -m $smlnj/installer.cm
2888    
2889    and everything happens automagically.
2890    
2891    Win32:  ML code senses value of environment variable SMLNJ_HOME.
2892    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
2893            and BINDIR.
2894    
2895    The new scheme guarantees that the ML code responsible for the installation
2896    is in sync with the APIs of the main system.  Also, the installer is
2897    somewhat faster because the installer script is precompiled.

2908    implementations of non-blocking operations from CML's Socket
2909    structure.

2914    Tag: blume-20030924-sockets
2915    Description:
2916    
2917    1. Fixed SOCKET API and implementation to match Basis spec.
2918       This required changing the internal representation of sockets to one
2919       that remembers (for each socket file descriptor) whether it is currently
2920       blocking or non-blocking.  This state is maintained lazily (i.e., a system
2921       call is made only if the state actually needs to change).
2922    
2923    2. OS-specific details of sockets were moved into separate files, thus
2924       making it possible to unify the bulk of the socket implementations
2925       between Unix and Win32.
2926    
2927    3. CML's socket API changed accordingly.
2928       (Note that we need to remove non-blocking functions from this API
2929       since they are redundant in the case of CML!)
2930    
2931    4. CML's socket implementation now makes use of non-blocking functions
2932       provided by Basis, thus removing all OS-dependent code from this part
2933       of CML.
2934    
2935    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

3048    Description:
3049    
3050    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3051    Modified config/install.bat to take advantage of it.  Also modified
3052    config/install.sh (and called it config/new-install.sh) to take advantage
3053    of it on Unix systems.  (The SML code is (supposed to be) platform-
3054    independent.)
3055    
3056    The installer can now install everything under Win32
3057    as well as under *nix as long as it compiles.
3058    
3059    Other changes:
3060    
3061      - made CML compile again under Win32
3062      - made eXene compile under Win32 (by providing a fake structure UnixSock
3063        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3064      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3065        same as type int;  under Win32 it isn't
3066      - fixed some slice-related problems in the win32-specific parts of CML
3067      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3068        (under Win32, the volume name is case-insensitive, and the
3069        OS.Path code compares volume names for equality)

3086    Description:
3087    
3088      1. Changed interface to vectors and arrays in Basis to match
3089         (draft) Basis spec.
3090      2. Added signatures and implementations of slices according to
3091         Basis spec.
3092      3. Edited source code throughout the system to make it compile again
3093         under 1. and 2.  (In some cases code had to be added to have it
3094         match the new signatures.)
3095      4. MLRISC should be backward-compatible: the copies of the originals
3096         of files that needed to change under 3. were retained, the .cm files
3097         check the compiler version number and use old versions when
3098         appropriate.
3099      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3100         dirstream -> string option (in accordance with Basis spec).
3101      6. When generating code that counts lines, ml-lex used function
3102         CharVector.foldli, taking advantage of its old interface.
3103         This has been replaced with the corresponding code from
3104         CharVectorSlice.  (html-lex must be re-lexed!)
3105      7. BitArray in smlnj-lib/Util has been extended/modified to match the
3106         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
3107      8. Removed temporary additions (fromInternal, toInternal) from the
3108         (now obsolete) IntInf in smlnj-lib/Util.
3109      9. Cleaned up structure Byte.
3110     10. Added localOffset, scan, and fromString to Date (according to spec).
3111         Cleaned/corrected implementation of Date.
3112         (Still need to check for correctness; implement better canonicalizeDate.)
3113     11. Added "scan" to signature IEEE_REAL.
3114     12. Some improvements to IntInf [in particular: efficiency-hack for
3115         mod and rem when second operand is 2 (for parity checks).]
3116     13. Changed representation of type Time.time, using a single IntInf.int
3117         value counting microseconds.  This considerably simplified the
3118         implementation of structure Time.  We now support negative time
3119         values; scan and fromString handle signs.
3120     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3121         ArraySlice).

3127    Description:
3128    
3129    This is a major update which comes with a version number bump
3130    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3131    and an implementation of IntInf in the Basis.
3132    
3133    There are a fairly large number of related changes and updates throughout
3134    the system:
3135    
3136    Basis:
3137            - Implemented IntInf.
3138            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3139            - Added some missing Real64 operations, most notably Real.toLargeInt.
3140            - Added FixedInt as a synonym for Int32.
3141    
3142    compiler:
3143            * Added support for a built-in intinf type.
3144              - literals
3145              - pattern matching
3146              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3147              - overloading on literals and operations
3148    
3149            This required adding a primitive type intinf, some additional
3150            primops, and implementations for several non-trivial intinf
3151            operations in Core.  (The intinf type is completely abstract
3152            to the compiler; all operations get delegated back to the Core.)
3153    
3154            * Intinf equality is handled by polyequal.  However, the compiler
3155            does not print its usual warning in this case (since polyequal
3156            is the right thing to do there).
3157    
3158            * Improved the organization of structure InlineT.
3159    
3160            * A word about conversion primops:
3161            If conversions involving intinf do not cancel out during
3162            CPS contract, then the compiler must insert calls to Core functions.
3163            Since all core access must be resolved already during the FLINT
3164            translate phase, it would be too late a the time of CPS contract
3165            to add new Core calls.  For this reason, conversion primops
3166            for intinf carry two arguments:  1. the numeric argument that
3167            they are supposed to convert, and 2. the Core function that
3168            can help with this conversion if necessary.  If CPS contract
3169            eliminates a primop, then the associated Core function becomes
3170            dead and goes away.  Intinf conversion primops that do not get
3171            eliminated by CPS contract get rewritten into calls of their
3172            core functions by a separate, new phase.
3173    
3174    interactive system:
3175            - Control.Print.intinfDepth controls max length of intinf constants
3176            being printed. (Analogous to Control.Print.stringDepth.)
3177            - Cleanup in printutil and pputil: got rid of unused stuff and
3178            duplicates; replaced some of the code with code that makes better
3179            use of library functionality.
3180    
3181    CM:
3182            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3183            are no longer silent.
3184    
3185    CKIT:
3186            Fixed mismatched uses of Int32 and LargeInt.  I always decided
3187            in favor of LargeInt -- which is now the same as IntInf.
3188            CKIT-knowledgable people should check whether this is what's
3189            intended and otherwise change things back to using Int32 or
3190            FixedInt.
3191    
3192    Throughout the code:
3193            Started using IntInf.int literals and built-in operations
3194            (e.g., comparison with 0) where this seems appropriate.

3201    Description:
3202    
3203    Merging changes from the mcz-branch development branch into trunk.
3204    These changes involve replacement of the emulated old prettyprinter
3205    interface with direct use of the SML/NJ Lib PP library, and fixing
3206    of a couple of bugs (895, 1186) relating to error messages.  A new
3207    prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
3208    has been added.

3214    Description:
3215    
3216    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
3217    
3218        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3219    
3220    This patch restores SML/NJ's ability to run under win32.  There are a
3221    number of changes, including fixes for several bugs that had gone
3222    unnoticed until now:
3223    
3224      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3225        trying to run the win32 version from within cygwin.)
3226    
3227      - There are a number of simple .bat scripts that substitute for their
3228        corresponding Unix shell-scripts.  (See below.)
3229    
3230      - The internals of ml-build have been modified slightly.  The main
3231        difference is that instead of calling ".link-sml" (or link-sml.bat)
3232        using OS.Process.system, the ML process delegates this task back
3233        to the script.  Otherwise problems arise in mixed environments such
3234        as Cygwin where scripts look and work like Unix scripts, but
3235        where OS.Process.system cannot run them.
3236    
3237      - In CM, the srcpath pickler used native pathname syntax -- which
3238        is incorrect in the case of cross-compilation.  The new pickle format
3239        is independent of platform-specific naming conventions.
3240    
3241      - Path configuration files (such as lib/pathconfig) can now choose
3242        between native and standard syntax.  Placing a line of the form
3243    
3244            standard!
3245    
3246        into the file causes all subsequent paths to be interpreted using
3247        CM standard pathname syntax (= Unix conventions); a line
3248    
3249            native!
3250    
3251        switches back to native style.  This was needed so that
3252        path config files can be written portably, see src/system/pathconfig.
3253    
3254      - Runtime system:
3255    
3256          - win32-filesys.c:  get_file_time and set_file_time now
3257            access modification time, not creation time.
3258    
3259          - I/O code made aware of new array representation.
3260    
3261          - Bug fixes in X86.prim.masm.
3262    
3263       - src/system/makeml made aware of win32. (For use under cygwin
3264            and other Unix-environments for windows.)
3265    
3266       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3267         which caused BinIO.inputAll to fail consistently.
3268    
3269    .bat scripts:
3270    
3271       Windows .bat scripts assume that SMLNJ_HOME is defined.
3272    
3273       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
3274         applications (sml, ml-yacc, ml-lex).
3275       - ml-build.bat: analogous to ml-build.
3276       - config\install.bat:  Analogous to config/install.sh.  This requires
3277         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3278         (nmake etc. must be on the path, and vcvars32 must have been run.)
3279         Moreover, sources for ml-lex and ml-yacc need to exist under src,
3280         and the bootfile hierarchy must have been unpacked under
3281         sml.boot.x86-win32.
3282         The script is very primitive and does a poor job at error checking.
3283         It only installs the base system, ml-lex, and ml-yacc.  No other
3284         libraries are being installed (i.e., you get only those that
3285         are part of the compiler.)
3286       - link-sml.bat:  analogous to .link-sml, but not currently used
3287    
3288    Unrelated bug fixes:
3289    
3290      - ml-nlffigen now exports structures ST_* corresponding to incomplete
3291        types.
3292      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
3293        otherwise.)
