691    
692    Fixed some bugs in new Div code in FLINT/trans/translate.sml.
693    
694    Also, changed the handling of "no core access":  When translate.sml
695    needs access to a core exception at a time when the core has not
696    been set up yet (this only happens when compiling system/smlnj/init/*),
697    then don't bother generating the corresponding tests.
698    
699    The old scheme was to generate a bogus value to be used in place of
700    the exception.  Unfortunately, that confuses the plambda type checker.
701    Moreover, it does not do any good, because at runtime we don't expect
702    such an exception to be ever raised.  (The code in system/smlnj/init/*
703    has to be written very carefully with this in mind!)

744    Description:
745    
746    CMB (and CM) now automatically defines the CM "preprocessor" symbol
747    NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
748    
749      (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
750       CM_SLAVE_MODE is defined in attached slaves while running CM.make
751       or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
752       while running CMB.make.  The point is that the single symbol
753       NO_PLUGINS is definde in all three cases.)
754    
755    I changed the three locations within the sources that get compiled
756    during CMB.make where ml-yacc or ml-lex input is processed: When
757    NO_PLUGINS defined, then the use of the mlyacc and mllex tools
758    is bypassed.
759    
760    When bootstrapping new versions of the compiler, there can be
761    situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
762    are not available or otherwise not operational.  In this case one can
763    manually define the NO_PLUGINS symbol prior to running CMB.make().  To
764    do so, the following command should be issued at the interactive
765    prompt:
766    
767       #set (CMB.symval "NO_PLUGINS") (SOME 1);
768    
769    A CMB.make with NO_PLUGINS defined relies on the existence of the
770    files that normally would be generated by ml-yacc and ml-lex.
771    (Copies of these files are in the repository.)

789    Changed the installation mechanism for CM tool plugins.  These are
790    just libaries and now get installed like ordinary libaries.
791    
792    There are now a number of new installation targets that give some
793    fine-grain control over what classes and suffixes are known, and what
794    they will map to.
795    See config/targets for details.
796    
797    The code that caused plugin installation as part of running a
798    tool's "build" script has been removed.  (The build script is for
799    building, not for installing.)

806    Added a boolean control named cm.tolerate-tool-failures (env. variable
807    name: CM_TOLERATE_TOOL_FAILURES).  The default is false and makes
808    CM fail if a shell tool reports a non-success exit status.  If
809    the control is set to true, then CM will press on after tool failures
810    in the event that the target files exist (even though they are
811    considered outdated).  Turning the control to true can be useful for
812    bootstrapping.

819    Merge of ml-lpt revisions for 110.64.
820    
821    The name of several ml-lpt-lib modules has changed:
822      Repair        => AntlrRepair
823      StreamPos     => AntlrStreamPos
824      ErrHandlerFn  => AntlrErrHandler
825      EBNF          => AntlrEBNF
826    
827    The ml-antlr specification format has changed: declarations such as
828    %tokens and nonterminal definitions can occur *multiple* times in the
829    same specification.  The semantics are such that each new declaration
830    extends the previous ones.  This does not apply to %start or %name,
831    of course.
832    
833    Importing a grammar via %import now includes *all* declarations in from
834    the imported grammar, except for %name, %entry, and %start.  Tokens
835    and nonterminals can be dropped using the new %dropping clause of the
836    %import directive; the separate %drop and %extend have been removed.
837    
838    We now allow optional type annotations on nonterminals, using the %nonterms
839    directive as in ml-yacc.
840    
841    The refcell construct is now implemented using SML's regular reference
842    cells, so the :== and !! notation has been deprecated.
843    
844    The ml-antlr tool now does much more checking of specifications, and
845    its error messages have been greatly improved.  Error repair for
846    generated parsers has been completely rewritten, and is now both
847    much faster and more accurate.
848    
849    ml-ulex is now more lenient with escape codes (non-SML-standard
850    escape codes are now interpreted literally, so e.g. \| denotes "|").
851    Also, character classes may now include a "-" character at the beginning
852    as is standard in most other regexp tools.
853    
854    All of these changes are documented in the user guide, which has
855    been updated and improved with this merge.

873    Preliminary commit of large ml-lpt revisions (more to come for 110.64).

875    %tokens and nonterminal definitions can occur *multiple* times in the
876    same specification.  The semantics are such that each new declaration
877    extends the previous ones.  Grammar extension constructs have also

882    
883    The ml-antlr tool now does much more checking of specifications, and
884    its error messages have been greatly improved.  There has also been
885    some work on the error repair process for generated parsers, but this
886    will be further improved in 110.64.

982    The staged allocation code base resides in MLRISC/staged-allocation,
983    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

1049    
1050    Brought ml-lpt manual up-to-date with the code.  Many minor
1051    improvements to the tools, and a few minor bugfixes.  Prepared
1052    ml-lpt-lib for integration with new UTF8 structure.  Changed
1053    the interface for creating streams in ml-ulex (we now support
1054    stream creation from several kinds of sources).  Overall, the
1055    tools are now quite stable, and their interfaces are unlikely to
1056    change in a way that would break compatibility.  More work,
1057    however, is needed in the documentation.

1064    Implemented library installer.  Moved CM plugin code for
1065    ml-burg, ml-lex, and ml-yacc out of CM source tree and into
1066    their respective trees.  Implemented CM plugin for ml-ulex
1067    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
1068    and ml-antlr.
1069    
1070    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
1071    CM tools.  (It turns out to be too messy to do otherwise because
1072    there is too much code that during installation relies on the presence
1073    of these tools -- resulting in a tricky ordering problem.)

1080    Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
1081    Modified CM's startup code to use shiftArgs as it processes
1082    command line arguments.  This way, the init code in each .sml-file
1083    or library that is mentioned at the top level will see only
1084    those arguments that have not yet been processed at this point.
1085    In other words, the init code can "seize control" and process the
1086    remaining command line.

1153    Description:
1154    
1155    Added code to CM's "standard shell tool" implementation which
1156    causes it to tolerate (with a warning) the situation where the shell
1157    command fails (e.g., due to the shell command's non-existence)
1158    as long as all target files exist.
1159    
1160    This makes it possible to, e.g., build ml-yacc from sources even if
1161    svn checkout messed up the time stamps on files in such a way that
1162    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
1163    be needed to re-process yacc.grm, but obviously it might not yet be
1164    available at that time.)

1204    Description:
1205    
1206    New working release (110.60).  NEW BOOTFILES!
1207    
1208    This is the first subversion-hosted release.  There are also changes
1209    to the directory layout.  Here is a table:
1210    
1211    (All pathnames are relative to the SML/NJ "root" directory.)
1212    
1213      config -> config
1214    
1215      src/cm -> base/cm
1216      src/compiler -> base/compiler
1217      src/runtime -> base/runtime
1218      src/system -> base/system
1219    
1220      src/cm/pgraph -> pgraph
1221    
1222      src/READMES -> base/READMES
1223      src/$notefile -> base/NOTES/$notefile
1224         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1225                           MACOSXINSTALL WININSTALL
1226    
1227      src/smlnj-lib -> smlnj-lib
1228      src/MLRISC -> MLRISC
1229      ckit -> ckit
1230      src/cml -> cml
1231      src/eXene -> eXene
1232      src/heap2asm -> heap2asm
1233      src/lexgen -> lexgen
1234      src/ml-burg -> ml-burg
1235      src/ml-lex -> ml-lex
1236      src/ml-yacc -> ml-yacc
1237      src/ml-nlffi-lib -> nlffi/lib
1238      src/ml-nlffigen -> nlffi/gen
1239      src/smlnj-c -> smlnj-c
1240      src/tools/TraceDebugProf -> trace-debug-profile
1241    
1242    In addition, there is also a new
1243    
1244      ml-lpt
1245    
1246    directory containing two new program generator tools: ml-ulex and
1247    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1248    LL(k) parser generator). These tools are currently "beta-quality"
1249    
1250    The latest versios of the sources can now be obtained anonymously
1251    via subversion.  For this, it is useful to first check out
1252    
1253       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1254    
1255    and put the resulting directory on your shell's PATH.  This provides
1256    access to three shell scripts: checkout-all.sh, stat-all.sh,
1257    and refresh-all.sh.
1258    
1259    To create a freshly checked-out copy of the sources, do
1260    
1261       checkout-all.sh [dir]
1262    
1263    where dir is the optional SML/NJ root directory (default is ".").
1264    
1265    This creates the above directory layout.  Each subdirectory of
1266    the root is under individual subversion control.  The stat-all.sh
1267    and refresh-al.sh scripts apply "svn stat" or "svn update" to
1268    each of these subtrees.
1269

1272    Date: 2006/11/02 12:20:00 CST
1273    Description:
1274    
1275    Reorganized directory layout.
1276    
1277    This is a temporary solution, more reorganization is to come.
1278    
1279    The basic idea is to have a number of toplevel trees, each corresponding
1280    to a well-defined part of the overall system.  Each part can be
1281    maintained individually, even in separate source repositories,
1282    although currently we still serve everything out of the main
1283    smlnj-gforge tree.
1284    
1285    Installer and and scripts have been updated to reflect the new
1286    layout.  The installer (base/src/system/smlnj/installer) is now
1287    "scriptable" to avoid burning too much knowledge about the
1288    layout into SML source code.  The main script used by the installer
1289    is in config/actions.
1290    
1291    The main change is that many of the subdirectories of what used to
1292    be known as "src" have moved to the toplevel.  The "src" directory
1293    itself has moved down into a subtree called "base".  (We may eventually
1294    get rid of the extra level of indirection represented by "src".)
1295    
1296    The layout is now as follows:
1297    
1298      toplevel tree name | default repository
1299                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1300      -------------------+----------------------------------------------------
1301      config             | $gf/config/trunk
1302                         |
1303      base               | $gf/sml/trunk
1304                         |
1305      smlnj-lib          | $gf/smlnj-lib/trunk
1306      MLRISC             | $gf/MLRISC/trunk
1307                         |
1308      ml-yacc            | $gf/ml-yacc/trunk
1309      ml-lex             | $gf/ml-lex/trunk
1310      ml-burg            | $gf/ml-burg/trunk
1311      lexgen             | $gf/lexgen/trunk
1312      heap2asm           | $gf/heap2asm/trunk
1313                         |
1314      cml                | $gf/cml/trunk
1315      eXene              | $gf/eXene/trunk
1316      ckit               | $gf/ckit/trunk
1317      nlffi              | $gf/nlffi/trunk
1318                         |
1319      smlnj-c            | $gf/smlnj-c/trunk
1320    
1321    In $gf/admin there are a few useful shell scripts for checking out
1322    and maintaining the entire collection of trees:
1323    
1324       admin/checkout-all.sh [dir]
1325          -- optionally creates dir and checks out all trees from their
1326             default repositories; if dir is missing, checkout into .
1327       admin/refresh-all.sh [dir]
1328          -- looks at all trees (from the above list) in dir (default: .)
1329             and runs "svn update" if the tree exists and is under
1330             subversion control;
1331             non-existing or non-subversion trees are skipped
1332       admin/stat-all.sh [dir]
1333          -- like refresh-all.sh, but runs "svn stat" instead

1359    
1360      Runtime:
1361        * fixed linking problem with NetBSD 3.x.
1362    
1363      Lexgen:

1365          way that ml-lex does
1366    
1367        * lexgen propagates exceptions the same way that ml-lex does
1368    
1369      CML:
1370        * Fixed a bug in the SyncVar polling functions (iGetPoll,
1371          mTakePoll, and mGetPoll) that could lead to livelock.

1479    Description:
1480    
1481    Hooked code for Darwin-specific Intel ABI into main compiler.
1482    (This is a temporary solution which relies on the fact that the
1483    compiler itself does not use NLFFI.  Eventually we need to divorce
1484    intel mac from generic x86 unix code and make separate sets of binaries.)

1513    Description:
1514    
1515    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
1516    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
1517    at the time when config/preloads is processed, the library has to
1518    be referred to by another name.  In 110.57 this would be
1519    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
1520    to be valid as well.)
1521    
1522    Thanks to Todd Wilson (Fresno) for alerting me to this issue.

1539    name of the CM metadata directory from the wrong place (because
1540    the physical location of basis.cm has changed).  Also, corrected the
1541    path anchor for $/html-lib.cm.  (Thanks to M. Fluet for pointing out
1542    these problems.)

1575    Tag: blume-22051115-versiontool
1576    Description:
1577    
1578    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
1579    file gets loaded as a tool -- by the equivalent of CM.make during the
1580    run of CMB.make.  Thus, CMB's path configuration is meaningless for
1581    it.  Instead, it has the status of "user code", so it should use
1582    $/basis.cm to refer to the Basis library.  (At least that's true for
1583    the purpose of bootstrapping the previous change.  In the future it
1584    might make sense to have versiontool.cm refer to
1585    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1586    compiler itself uses.)
1587    
1588    Also patched src/system/testml to have it activate those extra anchor
1589    bindings in config/extrapathconfig.

1594    Tag: blume-22051115-libraries
1595    Description:
1596    
1597    This change affects the way the following libraries are tied into
1598    the system:
1599    
1600       $/basis.cm
1601       $/smlnj-lib.cm
1602       $/pp-lib.cm
1603       $/controls-lib.cm
1604       $/html-lib.cm
1605       $/ml-yacc-lib.cm
1606    
1607    These libraries are now internally (as seen from the source code
1608    of the implementation itself) known by the following names:
1609    
1610       $smlnj/basis/basis.cm
1611       $smlnj/smlnj-lib/smlnj-lib.cm
1612       $smlnj/smlnj-lib/pp-lib.cm
1613       $smlnj/smlnj-lib/controls-lib.cm
1614       $smlnj/smlnj-lib/html-lib.cm
1615       $smlnj/ml-yacc/ml-yacc-lib.cm
1616    
1617    This makes it possible to work with code that requires different
1618    versions of these libraries, and which refers to these libraries using
1619    their "default" names (i.e., the first set of names above).  In other
1620    words, one can un-define or re-define those default names without
1621    compromising the proper functioning of the compiler itself.
1622    
1623    A similar procedure had already been performed for several of the
1624    MLRISC libraries that are linked into the compiler.  I did some
1625    cleanup on this code.
1626    
1627    A new file in the config directory (named extrapathconfig) is
1628    responsible for setting up path anchors that the compiler itself does
1629    not need, but that are typically required by user code.

1809    Description:
1810    
1811    Added mechanism for re-creating a heap file for the interactive system
1812    after configuration variables have been changed.
1813    
1814       CM.redump_heap : string -> unit
1815    
1816    This is much like SMLofNJ.exportML, but starting from the resulting
1817    heap does not return to the caller of CM.redump_heap but
1818    restarts the interactive system from scratch.  The original call of
1819    CM.redump_heap does not return but ends the interactive session.
1820    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1821    
1822    Internally, redump_heap winds the dynamic execution context back to
1823    the point where the original heap image was created and re-executes
1824    the heap image generation code in the boot code.

1868    Fixed serious bug (brown paper bag variety) in new implementation of
1869    structure Atom in CML.  (I had accidentally used a mailbox instead of
1870    an mvar, leaving the door open for races.)

1940    Tag: blume-20050114-heap2exec
1941    Description:
1942    
1943    Implemented new (but still experimental) heap2exec facility.  This is
1944    tested under Mac OS X and should work under Linux (will test shortly).
1945    It will probably also work on the Sparc (will test some time later).
1946    
1947      - removed old "HACKED_STANDALONE" hack from runtime
1948    
1949    To be able to test this, uncomment the request for "heap2asm" in
1950    config/targets prior to installation.  (Notice that this is different
1951    from "heap2exec" mentioned below.  Not a typo.)
1952    
1953    To perform an actual test, run the command
1954    
1955       $ bin/heap2exec heapfile execfile
1956    
1957    (You can put heap2exec on your shell's path.)
1958    
1959    For example, run
1960    
1961      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1962    
1963    This will create a standalone executable called "mly" which you can
1964    then invoke directly as a command.

2109    Tag: blume-20041124-position
2110    Description:
2111    
2112    The compiler can now be compiled in a mode that makes structure Position
2113    equal to Int64.  The default, however, is unchanged (Position = Int31)
2114    for the time being.
2115    
2116    To enable 64-bit positions, use the following procedure:
2117    
2118    1. Start sml
2119    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
2120    3. Type
2121          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
2122    4. Run CMB.make() as usual.
2123    
2124    This is barely tested.  The only test so far was a little SML program
2125    counting the number of characters in an 8-gigabyte file by
2126    reading it character-by-character.  That test was successful.
2127    
2128    In support of 64-bit positions, a number of new functions have been
2129    added to the runtime system.

2172    - Stripped down the versiontool: It now only handles the version number.
2173      The date string is generated at bootstrap time (during makeml).
2174    
2175    - In a previous commit, fixed a minor issue with how polyequal is being
2176      translated.  In particular, the code now "looks through" abstractions.
2177      This results in slightly fewer polyEqual warnings and hopefully slightly
2178      more efficient code.  Important examples for where this matters are
2179      the new int64 and word64 types.

2196    All the pieces of Word64 are now there, with the exception of the
2197    conversions from and to LargeWord. (Eventually these need to be identities,
2198    but for the time being they don't even make sense because LargeWord is
2199    32-bit wide.)
2200    
2201    Also started to add similar support for Int64, but major pieces of that
2202    are still missing.

2208    Description:
2209    
2210    Structure Word64 is now (almost) complete, word literals and patterns
2211    seem to work.  There are a few odd pieces missing.  In particular,
2212    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2213    at the moment.
2214    
2215    Making Word64 official would mean that LargeWord becomes Word64.  But
2216    this requires extreme care because most word-word conversions have to
2217    go through LargeWord, so making a mistake means loss of efficiency or
2218    worse.  Eventually there will be a solution similar to (but actually
2219    simpler than) what I did with IntInf.

2249    Also:
2250    
2251      - Changend config/srcarchiveurl from a file just
2252        containing the URL string into a file containing
2253        shell script code.  The code has access to the $VERSION variable.
2254      - Made corresponding changes to config/install.sh and config/unpack.
2255      - Default contents of config/srcarchiveurl uses $VERSION and
2256        normally does not have to be edited to reflect a version change.
2257    
2258      (As a result, a version change can be done by just editing
2259       config/version, the rest is now automatic.)
