36    Description:
37    
38    Added boolean literals (true and false) to the conditional-expression
39    syntax in CM.  Thus, you can write
40    
41    #if true
42      structure Foo
43    #endif
44    
45    in a CM file.  This change is meant to make it easier to use autoconf
46    to configure the build process of an SML application.

655    
656    Fixed some bugs in new Div code in FLINT/trans/translate.sml.
657    
658    Also, changed the handling of "no core access":  When translate.sml
659    needs access to a core exception at a time when the core has not
660    been set up yet (this only happens when compiling system/smlnj/init/*),
661    then don't bother generating the corresponding tests.
662    
663    The old scheme was to generate a bogus value to be used in place of
664    the exception.  Unfortunately, that confuses the plambda type checker.
665    Moreover, it does not do any good, because at runtime we don't expect
666    such an exception to be ever raised.  (The code in system/smlnj/init/*
667    has to be written very carefully with this in mind!)

708    Description:
709    
710    CMB (and CM) now automatically defines the CM "preprocessor" symbol
711    NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
712    
713      (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
714       CM_SLAVE_MODE is defined in attached slaves while running CM.make
715       or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
716       while running CMB.make.  The point is that the single symbol
717       NO_PLUGINS is definde in all three cases.)
718    
719    I changed the three locations within the sources that get compiled
720    during CMB.make where ml-yacc or ml-lex input is processed: When
721    NO_PLUGINS defined, then the use of the mlyacc and mllex tools
722    is bypassed.
723    
724    When bootstrapping new versions of the compiler, there can be
725    situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
726    are not available or otherwise not operational.  In this case one can
727    manually define the NO_PLUGINS symbol prior to running CMB.make().  To
728    do so, the following command should be issued at the interactive
729    prompt:
730    
731       #set (CMB.symval "NO_PLUGINS") (SOME 1);
732    
733    A CMB.make with NO_PLUGINS defined relies on the existence of the
734    files that normally would be generated by ml-yacc and ml-lex.
735    (Copies of these files are in the repository.)

753    Changed the installation mechanism for CM tool plugins.  These are
754    just libaries and now get installed like ordinary libaries.
755    
756    There are now a number of new installation targets that give some
757    fine-grain control over what classes and suffixes are known, and what
758    they will map to.
759    See config/targets for details.
760    
761    The code that caused plugin installation as part of running a
762    tool's "build" script has been removed.  (The build script is for
763    building, not for installing.)

771    name: CM_TOLERATE_TOOL_FAILURES).  The default is false and makes
772    CM fail if a shell tool reports a non-success exit status.  If
773    the control is set to true, then CM will press on after tool failures
774    in the event that the target files exist (even though they are
775    considered outdated).  Turning the control to true can be useful for
776    bootstrapping.

783    Merge of ml-lpt revisions for 110.64.
784    
785    The name of several ml-lpt-lib modules has changed:
786      Repair        => AntlrRepair
787      StreamPos     => AntlrStreamPos
788      ErrHandlerFn  => AntlrErrHandler
789      EBNF          => AntlrEBNF
790    
791    The ml-antlr specification format has changed: declarations such as
792    %tokens and nonterminal definitions can occur *multiple* times in the
793    same specification.  The semantics are such that each new declaration
794    extends the previous ones.  This does not apply to %start or %name,
795    of course.
796    
797    Importing a grammar via %import now includes *all* declarations in from
798    the imported grammar, except for %name, %entry, and %start.  Tokens
799    and nonterminals can be dropped using the new %dropping clause of the
800    %import directive; the separate %drop and %extend have been removed.
801    
802    We now allow optional type annotations on nonterminals, using the %nonterms
803    directive as in ml-yacc.
804    
805    The refcell construct is now implemented using SML's regular reference
806    cells, so the :== and !! notation has been deprecated.
807    
808    The ml-antlr tool now does much more checking of specifications, and
809    its error messages have been greatly improved.  Error repair for
810    generated parsers has been completely rewritten, and is now both
811    much faster and more accurate.
812    
813    ml-ulex is now more lenient with escape codes (non-SML-standard
814    escape codes are now interpreted literally, so e.g. \| denotes "|").
815    Also, character classes may now include a "-" character at the beginning
816    as is standard in most other regexp tools.
817    
818    All of these changes are documented in the user guide, which has
819    been updated and improved with this merge.

840    same specification.  The semantics are such that each new declaration

847    The ml-antlr tool now does much more checking of specifications, and

1012    Description:
1013    
1014    Brought ml-lpt manual up-to-date with the code.  Many minor
1015    improvements to the tools, and a few minor bugfixes.  Prepared
1016    ml-lpt-lib for integration with new UTF8 structure.  Changed
1017    the interface for creating streams in ml-ulex (we now support
1018    stream creation from several kinds of sources).  Overall, the
1019    tools are now quite stable, and their interfaces are unlikely to
1020    change in a way that would break compatibility.  More work,
1021    however, is needed in the documentation.

1026    Description:
1027    
1028    Implemented library installer.  Moved CM plugin code for
1029    ml-burg, ml-lex, and ml-yacc out of CM source tree and into
1030    their respective trees.  Implemented CM plugin for ml-ulex
1031    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
1032    and ml-antlr.
1033    
1034    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
1035    CM tools.  (It turns out to be too messy to do otherwise because
1036    there is too much code that during installation relies on the presence
1037    of these tools -- resulting in a tricky ordering problem.)

1043    
1044    Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
1045    Modified CM's startup code to use shiftArgs as it processes
1046    command line arguments.  This way, the init code in each .sml-file
1047    or library that is mentioned at the top level will see only
1048    those arguments that have not yet been processed at this point.
1049    In other words, the init code can "seize control" and process the
1050    remaining command line.

1117    Description:
1118    
1119    Added code to CM's "standard shell tool" implementation which
1120    causes it to tolerate (with a warning) the situation where the shell
1121    command fails (e.g., due to the shell command's non-existence)
1122    as long as all target files exist.
1123    
1124    This makes it possible to, e.g., build ml-yacc from sources even if
1125    svn checkout messed up the time stamps on files in such a way that
1126    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
1127    be needed to re-process yacc.grm, but obviously it might not yet be
1128    available at that time.)

1168    Description:
1169    
1170    New working release (110.60).  NEW BOOTFILES!
1171    
1172    This is the first subversion-hosted release.  There are also changes
1173    to the directory layout.  Here is a table:
1174    
1175    (All pathnames are relative to the SML/NJ "root" directory.)
1176    
1177      config -> config
1178    
1179      src/cm -> base/cm
1180      src/compiler -> base/compiler
1181      src/runtime -> base/runtime
1182      src/system -> base/system
1183    
1184      src/cm/pgraph -> pgraph
1185    
1186      src/READMES -> base/READMES
1187      src/$notefile -> base/NOTES/$notefile
1188         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1189                           MACOSXINSTALL WININSTALL
1190    
1191      src/smlnj-lib -> smlnj-lib
1192      src/MLRISC -> MLRISC
1193      ckit -> ckit
1194      src/cml -> cml
1195      src/eXene -> eXene
1196      src/heap2asm -> heap2asm
1197      src/lexgen -> lexgen
1198      src/ml-burg -> ml-burg
1199      src/ml-lex -> ml-lex
1200      src/ml-yacc -> ml-yacc
1201      src/ml-nlffi-lib -> nlffi/lib
1202      src/ml-nlffigen -> nlffi/gen
1203      src/smlnj-c -> smlnj-c
1204      src/tools/TraceDebugProf -> trace-debug-profile
1205    
1206    In addition, there is also a new
1207    
1208      ml-lpt
1209    
1210    directory containing two new program generator tools: ml-ulex and
1211    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1212    LL(k) parser generator). These tools are currently "beta-quality"
1213    
1214    The latest versios of the sources can now be obtained anonymously
1215    via subversion.  For this, it is useful to first check out
1216    
1217       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1218    
1219    and put the resulting directory on your shell's PATH.  This provides
1220    access to three shell scripts: checkout-all.sh, stat-all.sh,
1221    and refresh-all.sh.
1222    
1223    To create a freshly checked-out copy of the sources, do
1224    
1225       checkout-all.sh [dir]
1226    
1227    where dir is the optional SML/NJ root directory (default is ".").
1228    
1229    This creates the above directory layout.  Each subdirectory of
1230    the root is under individual subversion control.  The stat-all.sh
1231    and refresh-al.sh scripts apply "svn stat" or "svn update" to
1232    each of these subtrees.
1233

1235    Name: Matthias Blume (http://www.tti-c.org/blume/)
1236    Date: 2006/11/02 12:20:00 CST
1237    Description:
1238    
1239    Reorganized directory layout.
1240    
1241    This is a temporary solution, more reorganization is to come.
1242    
1243    The basic idea is to have a number of toplevel trees, each corresponding
1244    to a well-defined part of the overall system.  Each part can be
1245    maintained individually, even in separate source repositories,
1246    although currently we still serve everything out of the main
1247    smlnj-gforge tree.
1248    
1249    Installer and and scripts have been updated to reflect the new
1250    layout.  The installer (base/src/system/smlnj/installer) is now
1251    "scriptable" to avoid burning too much knowledge about the
1252    layout into SML source code.  The main script used by the installer
1253    is in config/actions.
1254    
1255    The main change is that many of the subdirectories of what used to
1256    be known as "src" have moved to the toplevel.  The "src" directory
1257    itself has moved down into a subtree called "base".  (We may eventually
1258    get rid of the extra level of indirection represented by "src".)
1259    
1260    The layout is now as follows:
1261    
1262      toplevel tree name | default repository
1263                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1264      -------------------+----------------------------------------------------
1265      config             | $gf/config/trunk
1266                         |
1267      base               | $gf/sml/trunk
1268                         |
1269      smlnj-lib          | $gf/smlnj-lib/trunk
1270      MLRISC             | $gf/MLRISC/trunk
1271                         |
1272      ml-yacc            | $gf/ml-yacc/trunk
1273      ml-lex             | $gf/ml-lex/trunk
1274      ml-burg            | $gf/ml-burg/trunk
1275      lexgen             | $gf/lexgen/trunk
1276      heap2asm           | $gf/heap2asm/trunk
1277                         |
1278      cml                | $gf/cml/trunk
1279      eXene              | $gf/eXene/trunk
1280      ckit               | $gf/ckit/trunk
1281      nlffi              | $gf/nlffi/trunk
1282                         |
1283      smlnj-c            | $gf/smlnj-c/trunk
1284    
1285    In $gf/admin there are a few useful shell scripts for checking out
1286    and maintaining the entire collection of trees:
1287    
1288       admin/checkout-all.sh [dir]
1289          -- optionally creates dir and checks out all trees from their
1290             default repositories; if dir is missing, checkout into .
1291       admin/refresh-all.sh [dir]
1292          -- looks at all trees (from the above list) in dir (default: .)
1293             and runs "svn update" if the tree exists and is under
1294             subversion control;
1295             non-existing or non-subversion trees are skipped
1296       admin/stat-all.sh [dir]
1297          -- like refresh-all.sh, but runs "svn stat" instead

1323    
1324      Runtime:
1325        * fixed linking problem with NetBSD 3.x.
1326    
1327      Lexgen:

1329          way that ml-lex does
1330    
1331        * lexgen propagates exceptions the same way that ml-lex does
1332    
1333      CML:
1334        * Fixed a bug in the SyncVar polling functions (iGetPoll,
1335          mTakePoll, and mGetPoll) that could lead to livelock.

1444    
1445    Hooked code for Darwin-specific Intel ABI into main compiler.
1446    (This is a temporary solution which relies on the fact that the
1447    compiler itself does not use NLFFI.  Eventually we need to divorce
1448    intel mac from generic x86 unix code and make separate sets of binaries.)

1477    Description:
1478    
1479    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
1480    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
1481    at the time when config/preloads is processed, the library has to
1482    be referred to by another name.  In 110.57 this would be
1483    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
1484    to be valid as well.)

1539    Tag: blume-22051115-versiontool
1540    Description:
1541    
1542    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
1543    file gets loaded as a tool -- by the equivalent of CM.make during the
1544    run of CMB.make.  Thus, CMB's path configuration is meaningless for
1545    it.  Instead, it has the status of "user code", so it should use
1546    $/basis.cm to refer to the Basis library.  (At least that's true for
1547    the purpose of bootstrapping the previous change.  In the future it
1548    might make sense to have versiontool.cm refer to
1549    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1550    compiler itself uses.)
1551    
1552    Also patched src/system/testml to have it activate those extra anchor
1553    bindings in config/extrapathconfig.

1558    Tag: blume-22051115-libraries
1559    Description:
1560    
1561    This change affects the way the following libraries are tied into
1562    the system:
1563    
1564       $/basis.cm
1565       $/smlnj-lib.cm
1566       $/pp-lib.cm
1567       $/controls-lib.cm
1568       $/html-lib.cm
1569       $/ml-yacc-lib.cm
1570    
1571    These libraries are now internally (as seen from the source code
1572    of the implementation itself) known by the following names:
1573    
1574       $smlnj/basis/basis.cm
1575       $smlnj/smlnj-lib/smlnj-lib.cm
1576       $smlnj/smlnj-lib/pp-lib.cm
1577       $smlnj/smlnj-lib/controls-lib.cm
1578       $smlnj/smlnj-lib/html-lib.cm
1579       $smlnj/ml-yacc/ml-yacc-lib.cm
1580    
1581    This makes it possible to work with code that requires different
1582    versions of these libraries, and which refers to these libraries using
1583    their "default" names (i.e., the first set of names above).  In other
1584    words, one can un-define or re-define those default names without
1585    compromising the proper functioning of the compiler itself.
1586    
1587    A similar procedure had already been performed for several of the
1588    MLRISC libraries that are linked into the compiler.  I did some
1589    cleanup on this code.
1590    
1591    A new file in the config directory (named extrapathconfig) is
1592    responsible for setting up path anchors that the compiler itself does
1593    not need, but that are typically required by user code.

1773    Description:
1774    
1775    Added mechanism for re-creating a heap file for the interactive system
1776    after configuration variables have been changed.
1777    
1778       CM.redump_heap : string -> unit
1779    
1780    This is much like SMLofNJ.exportML, but starting from the resulting
1781    heap does not return to the caller of CM.redump_heap but
1782    restarts the interactive system from scratch.  The original call of
1783    CM.redump_heap does not return but ends the interactive session.
1784    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1785    
1786    Internally, redump_heap winds the dynamic execution context back to
1787    the point where the original heap image was created and re-executes
1788    the heap image generation code in the boot code.

1850    Brought back SMLofNJ.Susp.  The underlying suspension type is the one
1851    implemented in Core -- which means that it is the same as the one used
1852    by the lazy extension.

1904    Tag: blume-20050114-heap2exec
1905    Description:
1906    
1907    Implemented new (but still experimental) heap2exec facility.  This is
1908    tested under Mac OS X and should work under Linux (will test shortly).
1909    It will probably also work on the Sparc (will test some time later).
1910    
1911      - removed old "HACKED_STANDALONE" hack from runtime
1912    
1913    To be able to test this, uncomment the request for "heap2asm" in
1914    config/targets prior to installation.  (Notice that this is different
1915    from "heap2exec" mentioned below.  Not a typo.)
1916    
1917    To perform an actual test, run the command
1918    
1919       $ bin/heap2exec heapfile execfile
1920    
1921    (You can put heap2exec on your shell's path.)
1922    
1923    For example, run
1924    
1925      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1926    
1927    This will create a standalone executable called "mly" which you can
1928    then invoke directly as a command.

2073    Tag: blume-20041124-position
2074    Description:
2075    
2076    The compiler can now be compiled in a mode that makes structure Position
2077    equal to Int64.  The default, however, is unchanged (Position = Int31)
2078    for the time being.
2079    
2080    To enable 64-bit positions, use the following procedure:
2081    
2082    1. Start sml
2083    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
2084    3. Type
2085          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
2086    4. Run CMB.make() as usual.
2087    
2088    This is barely tested.  The only test so far was a little SML program
2089    counting the number of characters in an 8-gigabyte file by
2090    reading it character-by-character.  That test was successful.
2091    
2092    In support of 64-bit positions, a number of new functions have been
2093    added to the runtime system.

2138    
2139    - In a previous commit, fixed a minor issue with how polyequal is being
2140      translated.  In particular, the code now "looks through" abstractions.
2141      This results in slightly fewer polyEqual warnings and hopefully slightly
2142      more efficient code.  Important examples for where this matters are
2143      the new int64 and word64 types.

2162    but for the time being they don't even make sense because LargeWord is
2163    32-bit wide.)
2164    
2165    Also started to add similar support for Int64, but major pieces of that
2166    are still missing.

2172    Description:
2173    
2174    Structure Word64 is now (almost) complete, word literals and patterns
2175    seem to work.  There are a few odd pieces missing.  In particular,
2176    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2177    at the moment.
2178    
2179    Making Word64 official would mean that LargeWord becomes Word64.  But
2180    this requires extreme care because most word-word conversions have to
2181    go through LargeWord, so making a mistake means loss of efficiency or
2182    worse.  Eventually there will be a solution similar to (but actually
2183    simpler than) what I did with IntInf.

2218      - Made corresponding changes to config/install.sh and config/unpack.
2219      - Default contents of config/srcarchiveurl uses $VERSION and
2220        normally does not have to be edited to reflect a version change.
2221    
2222      (As a result, a version change can be done by just editing
2223       config/version, the rest is now automatic.)

2263    Tag: blume-20041020-standalone-backtrace
2264    Description:
2265    
2266    Added a mechanism for getting back-trace information from standalone
2267    programs.  Here is how it works:
2268    
2269       1. The part of the program from which you want to get backtrace
2270          information (usually the whole program) should be wrapped with
2271          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
2272          main program could be modified from something like
2273    
2274             fun main (pgm, args) = ...
2275    
2276         to
2277    
2278            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2279    
2280       2. To be able to access BackTrace.monitor, you have to add
2281          library $smlnj-tdp/plugins.cm to the .cm file that contains your
2282          main function.
2283    
2284       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2285          CM might have created in the past for your project).
2286    
2287       4. Build the system using this command line:
2288    
2289             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2290                      myprog.cm MyProg.main myprog
2291    
2292          instead of the usual
2293    
2294             ml-build myprog.cm MyProg.main myprog
2295    
2296    I changed a library name:
2297    
2298       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2299    
2300    New libraries:
2301    
2302       $smlnj-tdp/back-trace.cm
2303          -- when loaded causes the back-trace plugin to be installed
2304       $smlnj-tdp/coverage.cm
2305          -- when loaded causes the coverage plugin to be installed

2321    Description:
2322    
2323    * Test coverage tool added!
2324    * Further reorganization of tracing-, debugging-, and profiling support:
2325    
2326        - moved original BTImp -- now called BackTrace -- into a separate
2327          library called $/trace-debug-profile.cm
2328        - eliminated all mentions of BTrace from SMLofNJ.Internals
2329        - only the instrumentation mechanism is now left in the compiler proper
2330        - BackTrace module is a plugin which is NOT plugged in by default
2331        - Coverage module is another such plugin
2332    
2333    To get the benefits of any of these plugin modules, the code in
2334    question must be compiled with tdp instrumentation turned on.  This
2335    can be done by setting SMLofNJ.Internals.TDP.mode to true.
2336    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2337    
2338    Plugins are selected at link time.  (Pre-compiled instrumented code
2339    can be re-loaded with different plugins in effect.)  When an
2340    instrumented module is linked, whatever plugins are at that time
2341    enabled will come into effect for that module.
2342    
2343    To enable the back-trace plugin, load library $/trace-debug-profile.cm
2344    and invoke BackTrace.install() (e.g., from the interactive prompt).
2345    To enable the coverage plugin, load the same library and invoke
2346    Coverage.install().
2347    
2348    Back-traces are generated automatically on uncaught exceptions and
2349    when the code in question explicitly invokes BackTrace.trigger().
2350    
2351    Coverage (and execution frequency-) information must be queried
2352    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2369    Some rationalization of names:

2374    This is is preparation of using the original back-trace
2375    instrumentation for other purposes.  "TDP" stands for
2376    Trace/Debug/Profile.
2377    
2378    The control flag controlling whether instrumentation is on or off is now
2379    registered under a different name, so instead of running sml as
2380    
2381     sml -Cinstrument.btrace-mode=true
2382    
2383    one has to say
2384    
2385     sml -Ctdp.instrument=true

2401    Description:
2402    
2403    Fixed handling of keywords in .cm files: After seeing "is" the lexer
2404    treats subsequent occurrences of "group", "library", "source", "is",
2405    "*", and "-" as ordinary identifiers rather than keywords.
2406    
2407    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
2408    is supposed to accept a tool argument called "source", but this did
2409    not work because of the clash with the keyword.

2452    Description:
2453    
2454    * Moved the "version" magic into its own little library under
2455      src/system/smlnj/internal.  This avoids expensive reconstruction of
2456      a stable src/compiler/core.cm.
2457    
2458    * At the same time, structure CompilerVersion is now known as
2459      structure SMLNJVersion.
2460    
2461    * Arranged for the version tool to NOT kick in when rebuilding the system
2462      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
2463      Also, loading the versiontool does not work when rebuilding the system
2464      because CM is not properly initialized at that time.

2469    Tag: blume-20040929-autoversion
2470    Description:
2471    
2472    Implemented some CM magic to have
2473        file src/compiler/TopLevel/main/version.sml
2474    generated automagically.
2475    The version is taken from two files: config/version and config/release.
2476    The first is expected to contain a two-part version number such as 110.49.
2477    The second should contain a single number, but it may be missing.
2478    
2479    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2480    time the version tool is loaded (which is the first time you say CMB.make),
2481    then the tool will increment the value stored in config/release every
2482    time CMB.make is invoked.
2483    
2484    The binfile format is now insensitive to anything beyond the first
2485    two components of a version number, so bumping the release does not render
2486    binfiles incompatible.  Auto-bumping can be used to keep track of versions
2487    during development without invalidating existing binfiles.
2488    
2489    In any case, every CMB.make updates the date information in version.sml.
2490    (This is the date that is printed in the banner.)

2503    Tag: blume-20040927-controls
2504    Description:
2505    
2506    Added two pieces of functionality to the Controls interface:
2507    
2508    1.   val save'restore: 'a control -> unit -> unit
2509    
2510       grabs the current value of the control in stage 1 and restores it
2511       in stage 2.
2512    
2513    2.   val set' : 'a control * 'a -> unit -> unit
2514    
2515       stores the given value into the control in stage 2 (i.e., delayed)
2516       but does all error checking in stage 1.
2517       (This is for string controls that need to do parse their argument --
2518        something that might fail.  In some cases, notably in CM, one
2519        already knows the intended argument but wants to delay the actual
2520        assignment until a time when error recovery would be more difficult.)
2521    
2522    Changed the handling of controls in tool arguments to classes "sml" and
2523    "lazysml":
2524       - use Controls.save'restore as a more robust way of restoring the
2525         old value (in particular: without having to re-parse the string)
2526       - use controls to handle the "overload" keyword in the init group
2527         (I believe this change actually fixes a long-standing obscure bug.)

2532    Tag: blume-20040927-lazysml
2533    Description:
2534    
2535    Added a new tool class called "lazysml" to CM's tool chest.  The only
2536    difference to "sml" is that compilation is done with Control.lazysml
2537    set to true.  A source of class "lazysml" is automatically recognized
2538    by a file name suffix of ".lml".
2539    
2540    In addition to the above feature, the original class "sml" now also
2541    supports a tool argument "lazy" which has the same effect.  As a
2542    result, the following three lines are equivalent:
2543    
2544        foo.sml : lazysml
2545        foo.sml : sml (lazy)
2546        foo.sml (lazy)
2547    
2548    The setting goes into effect both during parsing and during
2549    compilation.  The original setting is restored right after parsing and
2550    after compilation, respectively.
2551    
2552    In addition to all the above, there is also a general mechanism to set
2553    ANY of the "controls" that are available at the command line via
2554    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
2555    apply as well. (In fact, "lazy" is implemented as a special case of
2556    the general mechanism.)
2557    
2558    The .cm file syntax uses a new keyword tool argument called "with".
2559    There are several ways of indicating the desired settings:
2560    
2561        foo.sml (with:parser.quotations=true)
2562        foo.sml (with:(name:parser.quotations value:true))
2563        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2564        foo.sml (with:(name1=value1 name2=value2 ...))
2565        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2566    
2567        etc.
2568    
2569    Another possible abbreviation is to leave out the =v or value:v part
2570    if the name refers to a boolean control (in which case the value is
2571    taken to be true).  Thus, one could get lazy sml also by saying:
2572    
2573        foo.sml (with:parser.lazy-keyword=true)
2574        foo.sml (with:parser.lazy-keyword)
2575        foo.sml (with:(name:parser.lazy-keyword value:true))
2576        foo.sml (with:(name:parser.lazy-keyword))

2723    Description:
2724    
2725    Bug fix from Carl Hauser:
2726    
2727    single_source_shortest_paths in dijkstra.sml was observed to get wrong
2728    answers (by comparing to single_source_shortest_paths in bellman-ford.sml).
2729    
2730    The problem is that following the expression A.update(dist,s,Num.zero)
2731    it is necessary to update the priority queue using Q.decreaseWeight(Q,s).

2737    Description:
2738    
2739    Fiddled with handling of command-line options:
2740    
2741      * sml now quits after processing the command line
2742        if -H, -S, -h<n>, or -s<n> appears as the last
2743        command-line argument
2744      * a new option -q terminates the session when encountered on
2745        the command line; subsequent arguments will be ignored
2746      * bug fixes: short (erroneous) arguments are no longer ignored
2747        completely

2753    Description:
2754    
2755      - Added minimal IBM assembly syntax support for PowerPC.
2756    
2757      - Cygwin: manually changed the file cygwin.def.  Some exported symbols have
2758        been altered in the runtime.  We need an automatic way to keep the file
2759        in sync.
