471    
472    - Aaron: fixed a number of bugs in ml-ulex.
473    - Matthias:
474       - added CM control "cm.force-tools"; this is false by default;
475         when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
476         will be forced to run regardless of whether or not their targets
477         are up-to-date
478       - changed installer code so that config/install.sh will re-build
479         heap images for all tools even if those heap images already existed

505    Description:
506    
507    3rd merge of base from primop-branch-3 into the trunk.
508    Additional bug fixes included:
509    
510     * Timer.cpu_timer, etc. type printing corrected (by making
511         Timer have opaque sig constraint in basis/Implementation/timer.sml)
512     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
513         Stefan Monnier)

518    Description:
519    
520    Fixed some bugs in new Div code in FLINT/trans/translate.sml.
521    
522    Also, changed the handling of "no core access":  When translate.sml
523    needs access to a core exception at a time when the core has not
524    been set up yet (this only happens when compiling system/smlnj/init/*),
525    then don't bother generating the corresponding tests.
526    
527    The old scheme was to generate a bogus value to be used in place of
528    the exception.  Unfortunately, that confuses the plambda type checker.
529    Moreover, it does not do any good, because at runtime we don't expect
530    such an exception to be ever raised.  (The code in system/smlnj/init/*
531    has to be written very carefully with this in mind!)

543    Description:
544    
545    FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
546    with an explicit test for zero division.  This should fixes several
547    regressions and makes it possible for downstream optimization phases
548    to treat these operations as "pure" when they are applied to unsigned
549    operands.

557    in contrast to the previous one, uses SSE registers and instructions
558    for all floating-point computations.

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

572    Description:
573    
574    CMB (and CM) now automatically defines the CM "preprocessor" symbol
575    NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
576    
577      (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
578       CM_SLAVE_MODE is defined in attached slaves while running CM.make
579       or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
580       while running CMB.make.  The point is that the single symbol
581       NO_PLUGINS is definde in all three cases.)
582    
583    I changed the three locations within the sources that get compiled
584    during CMB.make where ml-yacc or ml-lex input is processed: When
585    NO_PLUGINS defined, then the use of the mlyacc and mllex tools
586    is bypassed.
587    
588    When bootstrapping new versions of the compiler, there can be
589    situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
590    are not available or otherwise not operational.  In this case one can
591    manually define the NO_PLUGINS symbol prior to running CMB.make().  To
592    do so, the following command should be issued at the interactive
593    prompt:
594    
595       #set (CMB.symval "NO_PLUGINS") (SOME 1);
596    
597    A CMB.make with NO_PLUGINS defined relies on the existence of the
598    files that normally would be generated by ml-yacc and ml-lex.
599    (Copies of these files are in the repository.)

615    Description:
616    
617    Changed the installation mechanism for CM tool plugins.  These are
618    just libaries and now get installed like ordinary libaries.
619    
620    There are now a number of new installation targets that give some
621    fine-grain control over what classes and suffixes are known, and what
622    they will map to.
623    See config/targets for details.
624    
625    The code that caused plugin installation as part of running a
626    tool's "build" script has been removed.  (The build script is for
627    building, not for installing.)

632    Description:
633    
634    Added a boolean control named cm.tolerate-tool-failures (env. variable
635    name: CM_TOLERATE_TOOL_FAILURES).  The default is false and makes
636    CM fail if a shell tool reports a non-success exit status.  If
637    the control is set to true, then CM will press on after tool failures
638    in the event that the target files exist (even though they are
639    considered outdated).  Turning the control to true can be useful for
640    bootstrapping.

645    Description:
646    
647    Merge of ml-lpt revisions for 110.64.
648    
649    The name of several ml-lpt-lib modules has changed:
650      Repair        => AntlrRepair
651      StreamPos     => AntlrStreamPos
652      ErrHandlerFn  => AntlrErrHandler
653      EBNF          => AntlrEBNF
654    
655    The ml-antlr specification format has changed: declarations such as
656    %tokens and nonterminal definitions can occur *multiple* times in the
657    same specification.  The semantics are such that each new declaration
658    extends the previous ones.  This does not apply to %start or %name,
659    of course.
660    
661    Importing a grammar via %import now includes *all* declarations in from
662    the imported grammar, except for %name, %entry, and %start.  Tokens
663    and nonterminals can be dropped using the new %dropping clause of the
664    %import directive; the separate %drop and %extend have been removed.
665    
666    We now allow optional type annotations on nonterminals, using the %nonterms
667    directive as in ml-yacc.
668    
669    The refcell construct is now implemented using SML's regular reference
670    cells, so the :== and !! notation has been deprecated.
671    
672    The ml-antlr tool now does much more checking of specifications, and
673    its error messages have been greatly improved.  Error repair for
674    generated parsers has been completely rewritten, and is now both
675    much faster and more accurate.
676    
677    ml-ulex is now more lenient with escape codes (non-SML-standard
678    escape codes are now interpreted literally, so e.g. \| denotes "|").
679    Also, character classes may now include a "-" character at the beginning
680    as is standard in most other regexp tools.
681    
682    All of these changes are documented in the user guide, which has
683    been updated and improved with this merge.

691    Merge of the primop3 branch (base) into the trunk to create 110.63.1.
692    Significant changes in FLINT and the front end, mostly having to do
693    with a reorganized system for handling primops.  Various bug fixes
694    and improvements in printing signatures.

700    
701    Preliminary commit of large ml-lpt revisions (more to come for 110.64).
702    The ml-antlr specification format has changed: declarations such as
703    %tokens and nonterminal definitions can occur *multiple* times in the
704    same specification.  The semantics are such that each new declaration
705    extends the previous ones.  Grammar extension constructs have also
706    changed.  We now allow type annotations on nonterminals.  Finally,
707    the refcell construct is now implemented using SML's regular reference
708    cells, so the :== and !! notation has been deprecated.  All of these
709    changes will appear in the 110.64 user guide for ml-lpt.
710    
711    The ml-antlr tool now does much more checking of specifications, and
712    its error messages have been greatly improved.  There has also been
713    some work on the error repair process for generated parsers, but this
714    will be further improved in 110.64.

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

803    Description:
804    
805    Added preliminary support in MLRISC for Staged Allocation, a technique
806    for specifying calling conventions (see
807    http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
808    Initially, we plan to use this code to generate C calls for the AMD64.
809    
810    The staged allocation code base resides in MLRISC/staged-allocation,
811    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

877    
878    Brought ml-lpt manual up-to-date with the code.  Many minor
879    improvements to the tools, and a few minor bugfixes.  Prepared
880    ml-lpt-lib for integration with new UTF8 structure.  Changed
881    the interface for creating streams in ml-ulex (we now support
882    stream creation from several kinds of sources).  Overall, the
883    tools are now quite stable, and their interfaces are unlikely to
884    change in a way that would break compatibility.  More work,
885    however, is needed in the documentation.

890    Description:
891    
892    Implemented library installer.  Moved CM plugin code for
893    ml-burg, ml-lex, and ml-yacc out of CM source tree and into
894    their respective trees.  Implemented CM plugin for ml-ulex
895    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
896    and ml-antlr.
897    
898    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
899    CM tools.  (It turns out to be too messy to do otherwise because
900    there is too much code that during installation relies on the presence
901    of these tools -- resulting in a tricky ordering problem.)

907    
908    Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
909    Modified CM's startup code to use shiftArgs as it processes
910    command line arguments.  This way, the init code in each .sml-file
911    or library that is mentioned at the top level will see only
912    those arguments that have not yet been processed at this point.
913    In other words, the init code can "seize control" and process the
914    remaining command line.

970    Description:
971    
972    Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to
973    get the c_cc termios data copied correctly.  Also moved the allocation
974    of the string to avoid problems if it caused a GC.
975    
976    Thanks to Timothy Bourke for the bug report and fix.

981    Description:
982    
983    Added code to CM's "standard shell tool" implementation which
984    causes it to tolerate (with a warning) the situation where the shell
985    command fails (e.g., due to the shell command's non-existence)
986    as long as all target files exist.
987    
988    This makes it possible to, e.g., build ml-yacc from sources even if
989    svn checkout messed up the time stamps on files in such a way that
990    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
991    be needed to re-process yacc.grm, but obviously it might not yet be
992    available at that time.)

1032    Description:
1033    
1034    New working release (110.60).  NEW BOOTFILES!
1035    
1036    This is the first subversion-hosted release.  There are also changes
1037    to the directory layout.  Here is a table:
1038    
1039    (All pathnames are relative to the SML/NJ "root" directory.)
1040    
1041      config -> config
1042    
1043      src/cm -> base/cm
1044      src/compiler -> base/compiler
1045      src/runtime -> base/runtime
1046      src/system -> base/system
1047    
1048      src/cm/pgraph -> pgraph
1049    
1050      src/READMES -> base/READMES
1051      src/$notefile -> base/NOTES/$notefile
1052         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1053                           MACOSXINSTALL WININSTALL
1054    
1055      src/smlnj-lib -> smlnj-lib
1056      src/MLRISC -> MLRISC
1057      ckit -> ckit
1058      src/cml -> cml
1059      src/eXene -> eXene
1060      src/heap2asm -> heap2asm
1061      src/lexgen -> lexgen
1062      src/ml-burg -> ml-burg
1063      src/ml-lex -> ml-lex
1064      src/ml-yacc -> ml-yacc
1065      src/ml-nlffi-lib -> nlffi/lib
1066      src/ml-nlffigen -> nlffi/gen
1067      src/smlnj-c -> smlnj-c
1068      src/tools/TraceDebugProf -> trace-debug-profile
1069    
1070    In addition, there is also a new
1071    
1072      ml-lpt
1073    
1074    directory containing two new program generator tools: ml-ulex and
1075    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1076    LL(k) parser generator). These tools are currently "beta-quality"
1077    
1078    The latest versios of the sources can now be obtained anonymously
1079    via subversion.  For this, it is useful to first check out
1080    
1081       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1082    
1083    and put the resulting directory on your shell's PATH.  This provides
1084    access to three shell scripts: checkout-all.sh, stat-all.sh,
1085    and refresh-all.sh.
1086    
1087    To create a freshly checked-out copy of the sources, do
1088    
1089       checkout-all.sh [dir]
1090    
1091    where dir is the optional SML/NJ root directory (default is ".").
1092    
1093    This creates the above directory layout.  Each subdirectory of
1094    the root is under individual subversion control.  The stat-all.sh
1095    and refresh-al.sh scripts apply "svn stat" or "svn update" to
1096    each of these subtrees.
1097

1100    Date: 2006/11/02 12:20:00 CST
1101    Description:
1102    
1103    Reorganized directory layout.
1104    
1105    This is a temporary solution, more reorganization is to come.
1106    
1107    The basic idea is to have a number of toplevel trees, each corresponding
1108    to a well-defined part of the overall system.  Each part can be
1109    maintained individually, even in separate source repositories,
1110    although currently we still serve everything out of the main
1111    smlnj-gforge tree.
1112    
1113    Installer and and scripts have been updated to reflect the new
1114    layout.  The installer (base/src/system/smlnj/installer) is now
1115    "scriptable" to avoid burning too much knowledge about the
1116    layout into SML source code.  The main script used by the installer
1117    is in config/actions.
1118    
1119    The main change is that many of the subdirectories of what used to
1120    be known as "src" have moved to the toplevel.  The "src" directory
1121    itself has moved down into a subtree called "base".  (We may eventually
1122    get rid of the extra level of indirection represented by "src".)
1123    
1124    The layout is now as follows:
1125    
1126      toplevel tree name | default repository
1127                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1128      -------------------+----------------------------------------------------
1129      config             | $gf/config/trunk
1130                         |
1131      base               | $gf/sml/trunk
1132                         |
1133      smlnj-lib          | $gf/smlnj-lib/trunk
1134      MLRISC             | $gf/MLRISC/trunk
1135                         |
1136      ml-yacc            | $gf/ml-yacc/trunk
1137      ml-lex             | $gf/ml-lex/trunk
1138      ml-burg            | $gf/ml-burg/trunk
1139      lexgen             | $gf/lexgen/trunk
1140      heap2asm           | $gf/heap2asm/trunk
1141                         |
1142      cml                | $gf/cml/trunk
1143      eXene              | $gf/eXene/trunk
1144      ckit               | $gf/ckit/trunk
1145      nlffi              | $gf/nlffi/trunk
1146                         |
1147      smlnj-c            | $gf/smlnj-c/trunk
1148    
1149    In $gf/admin there are a few useful shell scripts for checking out
1150    and maintaining the entire collection of trees:
1151    
1152       admin/checkout-all.sh [dir]
1153          -- optionally creates dir and checks out all trees from their
1154             default repositories; if dir is missing, checkout into .
1155       admin/refresh-all.sh [dir]
1156          -- looks at all trees (from the above list) in dir (default: .)
1157             and runs "svn update" if the tree exists and is under
1158             subversion control;
1159             non-existing or non-subversion trees are skipped
1160       admin/stat-all.sh [dir]
1161          -- like refresh-all.sh, but runs "svn stat" instead

1178    New working version (110.59).  NEW BOOTFILES!
1179    
1180    I am freezing 110.59.  Changes other than the version-number increase:
1181    
1182      eXene:
1183    
1184         * committed changes to eXene from Alley Stoughton:
1185             "fixed bugs in X authorization and resource handling, as well
1186              as in the pile and viewport widgets"
1187    
1188      Runtime:
1189        * fixed linking problem with NetBSD 3.x.
1190    
1191      Lexgen:
1192        * lexgen tool handles non-ascii characters in 7-bit mode the same
1193          way that ml-lex does
1194    
1195        * lexgen propagates exceptions the same way that ml-lex does
1196    
1197      CML:
1198        * Fixed a bug in the SyncVar polling functions (iGetPoll,
1199          mTakePoll, and mGetPoll) that could lead to livelock.

1343    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
1344    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
1345    at the time when config/preloads is processed, the library has to
1346    be referred to by another name.  In 110.57 this would be
1347    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
1348    to be valid as well.)

1403    Tag: blume-22051115-versiontool
1404    Description:
1405    
1406    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
1407    file gets loaded as a tool -- by the equivalent of CM.make during the
1408    run of CMB.make.  Thus, CMB's path configuration is meaningless for
1409    it.  Instead, it has the status of "user code", so it should use
1410    $/basis.cm to refer to the Basis library.  (At least that's true for
1411    the purpose of bootstrapping the previous change.  In the future it
1412    might make sense to have versiontool.cm refer to
1413    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1414    compiler itself uses.)
1415    
1416    Also patched src/system/testml to have it activate those extra anchor
1417    bindings in config/extrapathconfig.

1422    Tag: blume-22051115-libraries
1423    Description:
1424    
1425    This change affects the way the following libraries are tied into
1426    the system:
1427    
1428       $/basis.cm
1429       $/smlnj-lib.cm
1430       $/pp-lib.cm
1431       $/controls-lib.cm
1432       $/html-lib.cm
1433       $/ml-yacc-lib.cm
1434    
1435    These libraries are now internally (as seen from the source code
1436    of the implementation itself) known by the following names:
1437    
1438       $smlnj/basis/basis.cm
1439       $smlnj/smlnj-lib/smlnj-lib.cm
1440       $smlnj/smlnj-lib/pp-lib.cm
1441       $smlnj/smlnj-lib/controls-lib.cm
1442       $smlnj/smlnj-lib/html-lib.cm
1443       $smlnj/ml-yacc/ml-yacc-lib.cm
1444    
1445    This makes it possible to work with code that requires different
1446    versions of these libraries, and which refers to these libraries using
1447    their "default" names (i.e., the first set of names above).  In other
1448    words, one can un-define or re-define those default names without
1449    compromising the proper functioning of the compiler itself.
1450    
1451    A similar procedure had already been performed for several of the
1452    MLRISC libraries that are linked into the compiler.  I did some
1453    cleanup on this code.
1454    
1455    A new file in the config directory (named extrapathconfig) is
1456    responsible for setting up path anchors that the compiler itself does
1457    not need, but that are typically required by user code.

1636    Tag: blume-20050516-redump-heap
1637    Description:
1638    
1639    Added mechanism for re-creating a heap file for the interactive system
1640    after configuration variables have been changed.
1641    
1642       CM.redump_heap : string -> unit
1643    
1644    This is much like SMLofNJ.exportML, but starting from the resulting
1645    heap does not return to the caller of CM.redump_heap but
1646    restarts the interactive system from scratch.  The original call of
1647    CM.redump_heap does not return but ends the interactive session.
1648    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1649    
1650    Internally, redump_heap winds the dynamic execution context back to
1651    the point where the original heap image was created and re-executes
1652    the heap image generation code in the boot code.

1768    Tag: blume-20050114-heap2exec
1769    Description:
1770    
1771    Implemented new (but still experimental) heap2exec facility.  This is
1772    tested under Mac OS X and should work under Linux (will test shortly).
1773    It will probably also work on the Sparc (will test some time later).
1774    
1775      - removed old "HACKED_STANDALONE" hack from runtime
1776    
1777    To be able to test this, uncomment the request for "heap2asm" in
1778    config/targets prior to installation.  (Notice that this is different
1779    from "heap2exec" mentioned below.  Not a typo.)
1780    
1781    To perform an actual test, run the command
1782    
1783       $ bin/heap2exec heapfile execfile
1784    
1785    (You can put heap2exec on your shell's path.)
1786    
1787    For example, run
1788    
1789      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1790    
1791    This will create a standalone executable called "mly" which you can
1792    then invoke directly as a command.

1838    Description:
1839    
1840        The Unix I/O library of SML/NJ on cygwin does not understand
1841    Windows style pathname, so problems arise when SMLNJ_HOME is set
1842    to a Windows style pathname.  _run-sml now converts SMLNJ_HOME
1843    to a POSIX pathname on cygwin.

1937    Tag: blume-20041124-position
1938    Description:
1939    
1940    The compiler can now be compiled in a mode that makes structure Position
1941    equal to Int64.  The default, however, is unchanged (Position = Int31)
1942    for the time being.
1943    
1944    To enable 64-bit positions, use the following procedure:
1945    
1946    1. Start sml
1947    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1948    3. Type
1949          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1950    4. Run CMB.make() as usual.
1951    
1952    This is barely tested.  The only test so far was a little SML program
1953    counting the number of characters in an 8-gigabyte file by
1954    reading it character-by-character.  That test was successful.
1955    
1956    In support of 64-bit positions, a number of new functions have been
1957    added to the runtime system.

1999    
2000    - Stripped down the versiontool: It now only handles the version number.
2001      The date string is generated at bootstrap time (during makeml).
2002    
2003    - In a previous commit, fixed a minor issue with how polyequal is being
2004      translated.  In particular, the code now "looks through" abstractions.
2005      This results in slightly fewer polyEqual warnings and hopefully slightly
2006      more efficient code.  Important examples for where this matters are
2007      the new int64 and word64 types.

2023    
2024    All the pieces of Word64 are now there, with the exception of the
2025    conversions from and to LargeWord. (Eventually these need to be identities,
2026    but for the time being they don't even make sense because LargeWord is
2027    32-bit wide.)
2028    
2029    Also started to add similar support for Int64, but major pieces of that
2030    are still missing.

2036    Description:
2037    
2038    Structure Word64 is now (almost) complete, word literals and patterns
2039    seem to work.  There are a few odd pieces missing.  In particular,
2040    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2041    at the moment.
2042    
2043    Making Word64 official would mean that LargeWord becomes Word64.  But
2044    this requires extreme care because most word-word conversions have to
2045    go through LargeWord, so making a mistake means loss of efficiency or
2046    worse.  Eventually there will be a solution similar to (but actually
2047    simpler than) what I did with IntInf.

2077    Also:
2078    
2079      - Changend config/srcarchiveurl from a file just
2080        containing the URL string into a file containing
2081        shell script code.  The code has access to the $VERSION variable.
2082      - Made corresponding changes to config/install.sh and config/unpack.
2083      - Default contents of config/srcarchiveurl uses $VERSION and
2084        normally does not have to be edited to reflect a version change.
2085    
2086      (As a result, a version change can be done by just editing
2087       config/version, the rest is now automatic.)

2108      - made sure the caller does not add the wrong number of bytes to the
2109        stack pointer after a call of a function returning a struct
2110        (the callee already pops the implicit argument which points to
2111         the space reserved for the result)

2127    Tag: blume-20041020-standalone-backtrace
2128    Description:
2129    
2130    Added a mechanism for getting back-trace information from standalone
2131    programs.  Here is how it works:
2132    
2133       1. The part of the program from which you want to get backtrace
2134          information (usually the whole program) should be wrapped with
2135          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
2136          main program could be modified from something like
2137    
2138             fun main (pgm, args) = ...
2139    
2140         to
2141    
2142            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2143    
2144       2. To be able to access BackTrace.monitor, you have to add
2145          library $smlnj-tdp/plugins.cm to the .cm file that contains your
2146          main function.
2147    
2148       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2149          CM might have created in the past for your project).
2150    
2151       4. Build the system using this command line:
2152    
2153             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2154                      myprog.cm MyProg.main myprog
2155    
2156          instead of the usual
2157    
2158             ml-build myprog.cm MyProg.main myprog
2159    
2160    I changed a library name:
2161    
2162       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2163    
2164    New libraries:
2165    
2166       $smlnj-tdp/back-trace.cm
2167          -- when loaded causes the back-trace plugin to be installed
2168       $smlnj-tdp/coverage.cm
2169          -- when loaded causes the coverage plugin to be installed

2185    Description:
2186    
2187    * Test coverage tool added!
2188    * Further reorganization of tracing-, debugging-, and profiling support:
2189    
2190        - moved original BTImp -- now called BackTrace -- into a separate
2191          library called $/trace-debug-profile.cm
2192        - eliminated all mentions of BTrace from SMLofNJ.Internals
2193        - only the instrumentation mechanism is now left in the compiler proper
2194        - BackTrace module is a plugin which is NOT plugged in by default
2195        - Coverage module is another such plugin
2196    
2197    To get the benefits of any of these plugin modules, the code in
2198    question must be compiled with tdp instrumentation turned on.  This
2199    can be done by setting SMLofNJ.Internals.TDP.mode to true.
2200    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2201    
2202    Plugins are selected at link time.  (Pre-compiled instrumented code
2203    can be re-loaded with different plugins in effect.)  When an
2204    instrumented module is linked, whatever plugins are at that time
2205    enabled will come into effect for that module.
2206    
2207    To enable the back-trace plugin, load library $/trace-debug-profile.cm
2208    and invoke BackTrace.install() (e.g., from the interactive prompt).
2209    To enable the coverage plugin, load the same library and invoke
2210    Coverage.install().
2211    
2212    Back-traces are generated automatically on uncaught exceptions and
2213    when the code in question explicitly invokes BackTrace.trigger().
2214    
2215    Coverage (and execution frequency-) information must be queried
2216    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2238    This is is preparation of using the original back-trace
2239    instrumentation for other purposes.  "TDP" stands for
2240    Trace/Debug/Profile.
2241    
2242    The control flag controlling whether instrumentation is on or off is now
2243    registered under a different name, so instead of running sml as
2244    
2245     sml -Cinstrument.btrace-mode=true

2271    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
2272    is supposed to accept a tool argument called "source", but this did
2273    not work because of the clash with the keyword.

2316    Description:
2317    
2318    * Moved the "version" magic into its own little library under
2319      src/system/smlnj/internal.  This avoids expensive reconstruction of
2320      a stable src/compiler/core.cm.
2321    
2322    * At the same time, structure CompilerVersion is now known as
2323      structure SMLNJVersion.
2324    
2325    * Arranged for the version tool to NOT kick in when rebuilding the system
2326      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
2327      Also, loading the versiontool does not work when rebuilding the system
2328      because CM is not properly initialized at that time.

2333    Tag: blume-20040929-autoversion
2334    Description:
2335    
2336    Implemented some CM magic to have
2337        file src/compiler/TopLevel/main/version.sml
2338    generated automagically.
2339    The version is taken from two files: config/version and config/release.
2340    The first is expected to contain a two-part version number such as 110.49.
2341    The second should contain a single number, but it may be missing.
2342    
2343    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2344    time the version tool is loaded (which is the first time you say CMB.make),
2345    then the tool will increment the value stored in config/release every
2346    time CMB.make is invoked.
2347    
2348    The binfile format is now insensitive to anything beyond the first
2349    two components of a version number, so bumping the release does not render
2350    binfiles incompatible.  Auto-bumping can be used to keep track of versions
2351    during development without invalidating existing binfiles.
2352    
2353    In any case, every CMB.make updates the date information in version.sml.
2354    (This is the date that is printed in the banner.)

2367    Tag: blume-20040927-controls
2368    Description:
2369    
2370    Added two pieces of functionality to the Controls interface:
2371    
2372    1.   val save'restore: 'a control -> unit -> unit
2373    
2374       grabs the current value of the control in stage 1 and restores it
2375       in stage 2.
2376    
2377    2.   val set' : 'a control * 'a -> unit -> unit
2378    
2379       stores the given value into the control in stage 2 (i.e., delayed)
2380       but does all error checking in stage 1.
2381       (This is for string controls that need to do parse their argument --
2382        something that might fail.  In some cases, notably in CM, one
2383        already knows the intended argument but wants to delay the actual
2384        assignment until a time when error recovery would be more difficult.)
2385    
2386    Changed the handling of controls in tool arguments to classes "sml" and
2387    "lazysml":
2388       - use Controls.save'restore as a more robust way of restoring the
2389         old value (in particular: without having to re-parse the string)
2390       - use controls to handle the "overload" keyword in the init group
2391         (I believe this change actually fixes a long-standing obscure bug.)

2396    Tag: blume-20040927-lazysml
2397    Description:
2398    
2399    Added a new tool class called "lazysml" to CM's tool chest.  The only
2400    difference to "sml" is that compilation is done with Control.lazysml
2401    set to true.  A source of class "lazysml" is automatically recognized
2402    by a file name suffix of ".lml".
2403    
2404    In addition to the above feature, the original class "sml" now also
2405    supports a tool argument "lazy" which has the same effect.  As a
2406    result, the following three lines are equivalent:
2407    
2408        foo.sml : lazysml
2409        foo.sml : sml (lazy)
2410        foo.sml (lazy)
2411    
2412    The setting goes into effect both during parsing and during
2413    compilation.  The original setting is restored right after parsing and
2414    after compilation, respectively.
2415    
2416    In addition to all the above, there is also a general mechanism to set
2417    ANY of the "controls" that are available at the command line via
2418    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
2419    apply as well. (In fact, "lazy" is implemented as a special case of
2420    the general mechanism.)
2421    
2422    The .cm file syntax uses a new keyword tool argument called "with".
2423    There are several ways of indicating the desired settings:
2424    
2425        foo.sml (with:parser.quotations=true)
2426        foo.sml (with:(name:parser.quotations value:true))
2427        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2428        foo.sml (with:(name1=value1 name2=value2 ...))
2429        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2430    
2431        etc.
2432    
2433    Another possible abbreviation is to leave out the =v or value:v part
2434    if the name refers to a boolean control (in which case the value is
2435    taken to be true).  Thus, one could get lazy sml also by saying:
2436    
2437        foo.sml (with:parser.lazy-keyword=true)
2438        foo.sml (with:parser.lazy-keyword)
2439        foo.sml (with:(name:parser.lazy-keyword value:true))
2440        foo.sml (with:(name:parser.lazy-keyword))

2698    Description:
2699    
2700    Added C_UNION to c-calls/c-types.sml and updated the machinery
2701    (ml-nlffigen, cproto.sml) that conveys C function interface
2702    information to the code generator.
2703    
2704    However, the actual architecture-specific implementation of function
2705    arguments and results that are C unions is still not implemented.
