44    Description:
45    
46    Added preliminary support in MLRISC for Staged Allocation, a technique
47    for specifying calling conventions (see
48    http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
49    Initially, we plan to use this code to generate C calls for the AMD64.
50    
51    The staged allocation code base resides in MLRISC/staged-allocation,
52    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

71        val _  = Word8Array.update(a1, 0, 0w128);
72    
73        x86MCEmitter crashed when the immediate operand to MOVB was outside
74    of the range -128 ... 127.  I've changed the code so that the range
75    check is disabled.   Only the low order 8 bits of the immediate operand
76    are now significant.

117    Description:
118    
119    Brought ml-lpt manual up-to-date with the code.  Many minor
120    improvements to the tools, and a few minor bugfixes.  Prepared
121    ml-lpt-lib for integration with new UTF8 structure.  Changed
122    the interface for creating streams in ml-ulex (we now support
123    stream creation from several kinds of sources).  Overall, the
124    tools are now quite stable, and their interfaces are unlikely to
125    change in a way that would break compatibility.  More work,
126    however, is needed in the documentation.

131    Description:
132    
133    Implemented library installer.  Moved CM plugin code for
134    ml-burg, ml-lex, and ml-yacc out of CM source tree and into
135    their respective trees.  Implemented CM plugin for ml-ulex
136    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
137    and ml-antlr.
138    
139    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
140    CM tools.  (It turns out to be too messy to do otherwise because
141    there is too much code that during installation relies on the presence
142    of these tools -- resulting in a tricky ordering problem.)

147    Description:
148    
149    Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
150    Modified CM's startup code to use shiftArgs as it processes
151    command line arguments.  This way, the init code in each .sml-file
152    or library that is mentioned at the top level will see only
153    those arguments that have not yet been processed at this point.
154    In other words, the init code can "seize control" and process the
155    remaining command line.

212    
213    Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to
214    get the c_cc termios data copied correctly.  Also moved the allocation
215    of the string to avoid problems if it caused a GC.
216    
217    Thanks to Timothy Bourke for the bug report and fix.

221    Date: 2006/12/08 09:50:00 CST
222    Description:
223    
224    Added code to CM's "standard shell tool" implementation which
225    causes it to tolerate (with a warning) the situation where the shell
226    command fails (e.g., due to the shell command's non-existence)
227    as long as all target files exist.
228    
229    This makes it possible to, e.g., build ml-yacc from sources even if
230    svn checkout messed up the time stamps on files in such a way that
231    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
232    be needed to re-process yacc.grm, but obviously it might not yet be
233    available at that time.)

250    rather than silently pressing on using bogus values.

256    
257    Use Say.vsay for printing the "[autoloading]" message, so
258    #set CM.Control.verbose false (or -Ccm.verbose=false) can be used
259    to suppress them.

273    Description:
274    
275    New working release (110.60).  NEW BOOTFILES!
276    
277    This is the first subversion-hosted release.  There are also changes
278    to the directory layout.  Here is a table:
279    
280    (All pathnames are relative to the SML/NJ "root" directory.)
281    
282      config -> config
283    
284      src/cm -> base/cm
285      src/compiler -> base/compiler
286      src/runtime -> base/runtime
287      src/system -> base/system
288    
289      src/cm/pgraph -> pgraph
290    
291      src/READMES -> base/READMES
292      src/$notefile -> base/NOTES/$notefile
293         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
294                           MACOSXINSTALL WININSTALL
295    
296      src/smlnj-lib -> smlnj-lib
297      src/MLRISC -> MLRISC
298      ckit -> ckit
299      src/cml -> cml
300      src/eXene -> eXene
301      src/heap2asm -> heap2asm
302      src/lexgen -> lexgen
303      src/ml-burg -> ml-burg
304      src/ml-lex -> ml-lex
305      src/ml-yacc -> ml-yacc
306      src/ml-nlffi-lib -> nlffi/lib
307      src/ml-nlffigen -> nlffi/gen
308      src/smlnj-c -> smlnj-c
309      src/tools/TraceDebugProf -> trace-debug-profile
310    
311    In addition, there is also a new
312    
313      ml-lpt
314    
315    directory containing two new program generator tools: ml-ulex and
316    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
317    LL(k) parser generator). These tools are currently "beta-quality"
318    
319    The latest versios of the sources can now be obtained anonymously
320    via subversion.  For this, it is useful to first check out
321    
322       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
323    
324    and put the resulting directory on your shell's PATH.  This provides
325    access to three shell scripts: checkout-all.sh, stat-all.sh,
326    and refresh-all.sh.
327    
328    To create a freshly checked-out copy of the sources, do
329    
330       checkout-all.sh [dir]
331    
332    where dir is the optional SML/NJ root directory (default is ".").
333    
334    This creates the above directory layout.  Each subdirectory of
335    the root is under individual subversion control.  The stat-all.sh
336    and refresh-al.sh scripts apply "svn stat" or "svn update" to
337    each of these subtrees.
338    
339    ----------------------------------------------------------------------
340    Name: Matthias Blume (http://www.tti-c.org/blume/)
341    Date: 2006/11/02 12:20:00 CST
342    Description:
343    
344    Reorganized directory layout.
345    
346    This is a temporary solution, more reorganization is to come.
347    
348    The basic idea is to have a number of toplevel trees, each corresponding
349    to a well-defined part of the overall system.  Each part can be
350    maintained individually, even in separate source repositories,
351    although currently we still serve everything out of the main
352    smlnj-gforge tree.
353    
354    Installer and and scripts have been updated to reflect the new
355    layout.  The installer (base/src/system/smlnj/installer) is now
356    "scriptable" to avoid burning too much knowledge about the
357    layout into SML source code.  The main script used by the installer
358    is in config/actions.
359    
360    The main change is that many of the subdirectories of what used to
361    be known as "src" have moved to the toplevel.  The "src" directory
362    itself has moved down into a subtree called "base".  (We may eventually
363    get rid of the extra level of indirection represented by "src".)
364    
365    The layout is now as follows:
366    
367      toplevel tree name | default repository
368                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
369      -------------------+----------------------------------------------------
370      config             | $gf/config/trunk
371                         |
372      base               | $gf/sml/trunk
373                         |
374      smlnj-lib          | $gf/smlnj-lib/trunk
375      MLRISC             | $gf/MLRISC/trunk
376                         |
377      ml-yacc            | $gf/ml-yacc/trunk
378      ml-lex             | $gf/ml-lex/trunk
379      ml-burg            | $gf/ml-burg/trunk
380      lexgen             | $gf/lexgen/trunk
381      heap2asm           | $gf/heap2asm/trunk
382                         |
383      cml                | $gf/cml/trunk
384      eXene              | $gf/eXene/trunk
385      ckit               | $gf/ckit/trunk
386      nlffi              | $gf/nlffi/trunk
387                         |
388      smlnj-c            | $gf/smlnj-c/trunk
389    
390    In $gf/admin there are a few useful shell scripts for checking out
391    and maintaining the entire collection of trees:
392    
393       admin/checkout-all.sh [dir]
394          -- optionally creates dir and checks out all trees from their
395             default repositories; if dir is missing, checkout into .
396       admin/refresh-all.sh [dir]
397          -- looks at all trees (from the above list) in dir (default: .)
398             and runs "svn update" if the tree exists and is under
399             subversion control;
400             non-existing or non-subversion trees are skipped
401       admin/stat-all.sh [dir]
402          -- like refresh-all.sh, but runs "svn stat" instead

419    New working version (110.59).  NEW BOOTFILES!
420    
421    I am freezing 110.59.  Changes other than the version-number increase:
422    
423      eXene:
424    
425         * committed changes to eXene from Alley Stoughton:
426             "fixed bugs in X authorization and resource handling, as well
427              as in the pile and viewport widgets"
428    
429      Runtime:
430        * fixed linking problem with NetBSD 3.x.
431    
432      Lexgen:
433        * lexgen tool handles non-ascii characters in 7-bit mode the same
434          way that ml-lex does
435    
436        * lexgen propagates exceptions the same way that ml-lex does
437    
438      CML:
439        * Fixed a bug in the SyncVar polling functions (iGetPoll,
440          mTakePoll, and mGetPoll) that could lead to livelock.

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

582  Description:  Description:
583    
584    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
585    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
586    at the time when config/preloads is processed, the library has to
587    be referred to by another name.  In 110.57 this would be
588    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
589    to be valid as well.)

644    Tag: blume-22051115-versiontool
645    Description:
646    
647    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
648    file gets loaded as a tool -- by the equivalent of CM.make during the
649    run of CMB.make.  Thus, CMB's path configuration is meaningless for
650    it.  Instead, it has the status of "user code", so it should use
651    $/basis.cm to refer to the Basis library.  (At least that's true for
652    the purpose of bootstrapping the previous change.  In the future it
653    might make sense to have versiontool.cm refer to
654    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
655    compiler itself uses.)
656    
657    Also patched src/system/testml to have it activate those extra anchor
658    bindings in config/extrapathconfig.

663    Tag: blume-22051115-libraries
664    Description:
665    
666    This change affects the way the following libraries are tied into
667    the system:
668    
669       $/basis.cm
670       $/smlnj-lib.cm
671       $/pp-lib.cm
672       $/controls-lib.cm
673       $/html-lib.cm
674       $/ml-yacc-lib.cm
675    
676    These libraries are now internally (as seen from the source code
677    of the implementation itself) known by the following names:
678    
679       $smlnj/basis/basis.cm
680       $smlnj/smlnj-lib/smlnj-lib.cm
681       $smlnj/smlnj-lib/pp-lib.cm
682       $smlnj/smlnj-lib/controls-lib.cm
683       $smlnj/smlnj-lib/html-lib.cm
684       $smlnj/ml-yacc/ml-yacc-lib.cm
685    
686    This makes it possible to work with code that requires different
687    versions of these libraries, and which refers to these libraries using
688    their "default" names (i.e., the first set of names above).  In other
689    words, one can un-define or re-define those default names without
690    compromising the proper functioning of the compiler itself.
691    
692    A similar procedure had already been performed for several of the
693    MLRISC libraries that are linked into the compiler.  I did some
694    cleanup on this code.
695    
696    A new file in the config directory (named extrapathconfig) is
697    responsible for setting up path anchors that the compiler itself does
698    not need, but that are typically required by user code.

877    Tag: blume-20050516-redump-heap
878    Description:
879    
880    Added mechanism for re-creating a heap file for the interactive system
881    after configuration variables have been changed.
882    
883       CM.redump_heap : string -> unit
884    
885    This is much like SMLofNJ.exportML, but starting from the resulting
886    heap does not return to the caller of CM.redump_heap but
887    restarts the interactive system from scratch.  The original call of
888    CM.redump_heap does not return but ends the interactive session.
889    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
890    
891    Internally, redump_heap winds the dynamic execution context back to
892    the point where the original heap image was created and re-executes
893    the heap image generation code in the boot code.

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

1010    Description:
1011    
1012    Implemented new (but still experimental) heap2exec facility.  This is
1013    tested under Mac OS X and should work under Linux (will test shortly).
1014    It will probably also work on the Sparc (will test some time later).
1015    
1016      - removed old "HACKED_STANDALONE" hack from runtime
1017    
1018    To be able to test this, uncomment the request for "heap2asm" in
1019    config/targets prior to installation.  (Notice that this is different
1020    from "heap2exec" mentioned below.  Not a typo.)
1021    
1022    To perform an actual test, run the command
1023    
1024       $ bin/heap2exec heapfile execfile
1025    
1026    (You can put heap2exec on your shell's path.)
1027    
1028    For example, run
1029    
1030      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1031    
1032    This will create a standalone executable called "mly" which you can
1033    then invoke directly as a command.

1178    Tag: blume-20041124-position
1179    Description:
1180    
1181    The compiler can now be compiled in a mode that makes structure Position
1182    equal to Int64.  The default, however, is unchanged (Position = Int31)
1183    for the time being.
1184    
1185    To enable 64-bit positions, use the following procedure:
1186    
1187    1. Start sml
1188    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1189    3. Type
1190          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1191    4. Run CMB.make() as usual.
1192    
1193    This is barely tested.  The only test so far was a little SML program
1194    counting the number of characters in an 8-gigabyte file by
1195    reading it character-by-character.  That test was successful.
1196    
1197    In support of 64-bit positions, a number of new functions have been
1198    added to the runtime system.

1241    - Stripped down the versiontool: It now only handles the version number.
1242      The date string is generated at bootstrap time (during makeml).
1243    
1244    - In a previous commit, fixed a minor issue with how polyequal is being
1245      translated.  In particular, the code now "looks through" abstractions.
1246      This results in slightly fewer polyEqual warnings and hopefully slightly
1247      more efficient code.  Important examples for where this matters are
1248      the new int64 and word64 types.

1265    All the pieces of Word64 are now there, with the exception of the

1267    but for the time being they don't even make sense because LargeWord is
1268    32-bit wide.)
1269    
1270    Also started to add similar support for Int64, but major pieces of that
1271    are still missing.

1277    Description:
1278    
1279    Structure Word64 is now (almost) complete, word literals and patterns
1280    seem to work.  There are a few odd pieces missing.  In particular,
1281    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1282    at the moment.
1283    
1284    Making Word64 official would mean that LargeWord becomes Word64.  But
1285    this requires extreme care because most word-word conversions have to
1286    go through LargeWord, so making a mistake means loss of efficiency or
1287    worse.  Eventually there will be a solution similar to (but actually
1288    simpler than) what I did with IntInf.

1322        shell script code.  The code has access to the $VERSION variable.
1323      - Made corresponding changes to config/install.sh and config/unpack.
1324      - Default contents of config/srcarchiveurl uses $VERSION and
1325        normally does not have to be edited to reflect a version change.
1326    
1327      (As a result, a version change can be done by just editing
1328       config/version, the rest is now automatic.)

1368    Tag: blume-20041020-standalone-backtrace
1369    Description:
1370    
1371    Added a mechanism for getting back-trace information from standalone
1372    programs.  Here is how it works:
1373    
1374       1. The part of the program from which you want to get backtrace
1375          information (usually the whole program) should be wrapped with
1376          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
1377          main program could be modified from something like
1378    
1379             fun main (pgm, args) = ...
1380    
1381         to
1382    
1383            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1384    
1385       2. To be able to access BackTrace.monitor, you have to add
1386          library $smlnj-tdp/plugins.cm to the .cm file that contains your
1387          main function.
1388    
1389       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1390          CM might have created in the past for your project).
1391    
1392       4. Build the system using this command line:
1393    
1394             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1395                      myprog.cm MyProg.main myprog
1396    
1397          instead of the usual
1398    
1399             ml-build myprog.cm MyProg.main myprog
1400    
1401    I changed a library name:
1402    
1403       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1404    
1405    New libraries:
1406    
1407       $smlnj-tdp/back-trace.cm
1408          -- when loaded causes the back-trace plugin to be installed
1409       $smlnj-tdp/coverage.cm
1410          -- when loaded causes the coverage plugin to be installed

1426    Description:
1427    
1428    * Test coverage tool added!
1429    * Further reorganization of tracing-, debugging-, and profiling support:
1430    
1431        - moved original BTImp -- now called BackTrace -- into a separate
1432          library called $/trace-debug-profile.cm
1433        - eliminated all mentions of BTrace from SMLofNJ.Internals
1434        - only the instrumentation mechanism is now left in the compiler proper
1435        - BackTrace module is a plugin which is NOT plugged in by default
1436        - Coverage module is another such plugin
1437    
1438    To get the benefits of any of these plugin modules, the code in
1439    question must be compiled with tdp instrumentation turned on.  This
1440    can be done by setting SMLofNJ.Internals.TDP.mode to true.
1441    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1442    
1443    Plugins are selected at link time.  (Pre-compiled instrumented code
1444    can be re-loaded with different plugins in effect.)  When an
1445    instrumented module is linked, whatever plugins are at that time
1446    enabled will come into effect for that module.
1447    
1448    To enable the back-trace plugin, load library $/trace-debug-profile.cm
1449    and invoke BackTrace.install() (e.g., from the interactive prompt).
1450    To enable the coverage plugin, load the same library and invoke
1451    Coverage.install().
1452    
1453    Back-traces are generated automatically on uncaught exceptions and
1454    when the code in question explicitly invokes BackTrace.trigger().
1455    
1456    Coverage (and execution frequency-) information must be queried
1457    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

1474    Some rationalization of names:

1477       etc.
1478    
1479    This is is preparation of using the original back-trace
1480    instrumentation for other purposes.  "TDP" stands for
1481    Trace/Debug/Profile.
1482    
1483    The control flag controlling whether instrumentation is on or off is now
1484    registered under a different name, so instead of running sml as
1485    
1486     sml -Cinstrument.btrace-mode=true
1487    
1488    one has to say
1489    
1490     sml -Ctdp.instrument=true

1506    Description:
1507    
1508    Fixed handling of keywords in .cm files: After seeing "is" the lexer
1509    treats subsequent occurrences of "group", "library", "source", "is",
1510    "*", and "-" as ordinary identifiers rather than keywords.
1511    
1512    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
1513    is supposed to accept a tool argument called "source", but this did
1514    not work because of the clash with the keyword.

1557    Description:
1558    
1559    * Moved the "version" magic into its own little library under
1560      src/system/smlnj/internal.  This avoids expensive reconstruction of
1561      a stable src/compiler/core.cm.
1562    
1563    * At the same time, structure CompilerVersion is now known as
1564      structure SMLNJVersion.
1565    
1566    * Arranged for the version tool to NOT kick in when rebuilding the system
1567      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
1568      Also, loading the versiontool does not work when rebuilding the system
1569      because CM is not properly initialized at that time.

1574    Tag: blume-20040929-autoversion
1575    Description:
1576    
1577    Implemented some CM magic to have
1578        file src/compiler/TopLevel/main/version.sml
1579    generated automagically.
1580    The version is taken from two files: config/version and config/release.
1581    The first is expected to contain a two-part version number such as 110.49.
1582    The second should contain a single number, but it may be missing.
1583    
1584    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
1585    time the version tool is loaded (which is the first time you say CMB.make),
1586    then the tool will increment the value stored in config/release every
1587    time CMB.make is invoked.
1588    
1589    The binfile format is now insensitive to anything beyond the first
1590    two components of a version number, so bumping the release does not render
1591    binfiles incompatible.  Auto-bumping can be used to keep track of versions
1592    during development without invalidating existing binfiles.
1593    
1594    In any case, every CMB.make updates the date information in version.sml.
1595    (This is the date that is printed in the banner.)

1608    Tag: blume-20040927-controls
1609    Description:
1610    
1611    Added two pieces of functionality to the Controls interface:
1612    
1613    1.   val save'restore: 'a control -> unit -> unit
1614    
1615       grabs the current value of the control in stage 1 and restores it
1616       in stage 2.
1617    
1618    2.   val set' : 'a control * 'a -> unit -> unit
1619    
1620       stores the given value into the control in stage 2 (i.e., delayed)
1621       but does all error checking in stage 1.
1622       (This is for string controls that need to do parse their argument --
1623        something that might fail.  In some cases, notably in CM, one
1624        already knows the intended argument but wants to delay the actual
1625        assignment until a time when error recovery would be more difficult.)
1626    
1627    Changed the handling of controls in tool arguments to classes "sml" and
1628    "lazysml":
1629       - use Controls.save'restore as a more robust way of restoring the
1630         old value (in particular: without having to re-parse the string)
1631       - use controls to handle the "overload" keyword in the init group
1632         (I believe this change actually fixes a long-standing obscure bug.)

1637    Tag: blume-20040927-lazysml
1638    Description:
1639    
1640    Added a new tool class called "lazysml" to CM's tool chest.  The only
1641    difference to "sml" is that compilation is done with Control.lazysml
1642    set to true.  A source of class "lazysml" is automatically recognized
1643    by a file name suffix of ".lml".
1644    
1645    In addition to the above feature, the original class "sml" now also
1646    supports a tool argument "lazy" which has the same effect.  As a
1647    result, the following three lines are equivalent:
1648    
1649        foo.sml : lazysml
1650        foo.sml : sml (lazy)
1651        foo.sml (lazy)
1652    
1653    The setting goes into effect both during parsing and during
1654    compilation.  The original setting is restored right after parsing and
1655    after compilation, respectively.
1656    
1657    In addition to all the above, there is also a general mechanism to set
1658    ANY of the "controls" that are available at the command line via
1659    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
1660    apply as well. (In fact, "lazy" is implemented as a special case of
1661    the general mechanism.)
1662    
1663    The .cm file syntax uses a new keyword tool argument called "with".
1664    There are several ways of indicating the desired settings:
1665    
1666        foo.sml (with:parser.quotations=true)
1667        foo.sml (with:(name:parser.quotations value:true))
1668        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
1669        foo.sml (with:(name1=value1 name2=value2 ...))
1670        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
1671    
1672        etc.
1673    
1674    Another possible abbreviation is to leave out the =v or value:v part
1675    if the name refers to a boolean control (in which case the value is
1676    taken to be true).  Thus, one could get lazy sml also by saying:
1677    
1678        foo.sml (with:parser.lazy-keyword=true)
1679        foo.sml (with:parser.lazy-keyword)
1680        foo.sml (with:(name:parser.lazy-keyword value:true))
1681        foo.sml (with:(name:parser.lazy-keyword))
