33    Description:
34    
35    Minor fix to ml-ulex backend for regexps that match any character
36    and perform a single action.  Previously the emitted code would
37    not allow the regexps to match any character at all.

118    Description:
119    
120    nlffi was updated to work on Windows. It needed to pass in the correct
121    value for the name of the kernel32 DLL to obtain 'base' bindings.

221    Date: 2007/10/18
222    Description:
223    
224    The GAS output now favors p2align over align, since the
225    former is guaranteed to be consistent over multiple architectures
226    and the latter is not.

303    Description:
304    
305    - Aaron: fixed a number of bugs in ml-ulex.
306    - Matthias:
307       - added CM control "cm.force-tools"; this is false by default;
308         when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
309         will be forced to run regardless of whether or not their targets
310         are up-to-date
311       - changed installer code so that config/install.sh will re-build
312         heap images for all tools even if those heap images already existed

317    Description:
318    
319    After Aaron Turon's bug fix for ml-ulex (handling the ^ character
320    in legacy mode), re-ran the lexer generator on all lex input files
321    and committed the results.
322    
323    This should fix the problem with ckit and nlffi that was reported
324    by Vesa A. Norrman.

338    Description:
339    
340    3rd merge of base from primop-branch-3 into the trunk.
341    Additional bug fixes included:
342    
343     * Timer.cpu_timer, etc. type printing corrected (by making
344         Timer have opaque sig constraint in basis/Implementation/timer.sml)
345     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
346         Stefan Monnier)

350    Date: 2007/05/31 11:40:00 CDT
351    Description:
352    
353    Fixed some bugs in new Div code in FLINT/trans/translate.sml.
354    
355    Also, changed the handling of "no core access":  When translate.sml
356    needs access to a core exception at a time when the core has not
357    been set up yet (this only happens when compiling system/smlnj/init/*),
358    then don't bother generating the corresponding tests.
359    
360    The old scheme was to generate a bogus value to be used in place of
361    the exception.  Unfortunately, that confuses the plambda type checker.
362    Moreover, it does not do any good, because at runtime we don't expect
363    such an exception to be ever raised.  (The code in system/smlnj/init/*
364    has to be written very carefully with this in mind!)

376    Description:
377    
378    FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
379    with an explicit test for zero division.  This should fixes several
380    regressions and makes it possible for downstream optimization phases
381    to treat these operations as "pure" when they are applied to unsigned
382    operands.

388    
389    Added the new MLRISC code generator for the AMD64.  This version,
390    in contrast to the previous one, uses SSE registers and instructions
391    for all floating-point computations.

397    
398    A number of fixes related to the formatting of dates.  These include fixes
399    for bugs #1415 and #1416.  We also now correctly handle format characters that
400    lie outside the specified set.

403    Name: Matthias Blume (http://www.tti-c.org/blume/)
404    Date: 2007/05/23 22:30:00 CDT
405    Description:
406    
407    CMB (and CM) now automatically defines the CM "preprocessor" symbol
408    NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
409    
410      (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
411       CM_SLAVE_MODE is defined in attached slaves while running CM.make
412       or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
413       while running CMB.make.  The point is that the single symbol
414       NO_PLUGINS is definde in all three cases.)
415    
416    I changed the three locations within the sources that get compiled
417    during CMB.make where ml-yacc or ml-lex input is processed: When
418    NO_PLUGINS defined, then the use of the mlyacc and mllex tools
419    is bypassed.
420    
421    When bootstrapping new versions of the compiler, there can be
422    situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
423    are not available or otherwise not operational.  In this case one can
424    manually define the NO_PLUGINS symbol prior to running CMB.make().  To
425    do so, the following command should be issued at the interactive
426    prompt:
427    
428       #set (CMB.symval "NO_PLUGINS") (SOME 1);
429    
430    A CMB.make with NO_PLUGINS defined relies on the existence of the
431    files that normally would be generated by ml-yacc and ml-lex.
432    (Copies of these files are in the repository.)

448    Description:
449    
450    Changed the installation mechanism for CM tool plugins.  These are
451    just libaries and now get installed like ordinary libaries.
452    
453    There are now a number of new installation targets that give some
454    fine-grain control over what classes and suffixes are known, and what
455    they will map to.
456    See config/targets for details.
457    
458    The code that caused plugin installation as part of running a
459    tool's "build" script has been removed.  (The build script is for
460    building, not for installing.)

465    Description:
466    
467    Added a boolean control named cm.tolerate-tool-failures (env. variable
468    name: CM_TOLERATE_TOOL_FAILURES).  The default is false and makes
469    CM fail if a shell tool reports a non-success exit status.  If
470    the control is set to true, then CM will press on after tool failures
471    in the event that the target files exist (even though they are
472    considered outdated).  Turning the control to true can be useful for
473    bootstrapping.

479    
480    Merge of ml-lpt revisions for 110.64.
481    
482    The name of several ml-lpt-lib modules has changed:
483      Repair        => AntlrRepair
484      StreamPos     => AntlrStreamPos
485      ErrHandlerFn  => AntlrErrHandler
486      EBNF          => AntlrEBNF
487    
488    The ml-antlr specification format has changed: declarations such as
489    %tokens and nonterminal definitions can occur *multiple* times in the
490    same specification.  The semantics are such that each new declaration
491    extends the previous ones.  This does not apply to %start or %name,
492    of course.
493    
494    Importing a grammar via %import now includes *all* declarations in from
495    the imported grammar, except for %name, %entry, and %start.  Tokens
496    and nonterminals can be dropped using the new %dropping clause of the
497    %import directive; the separate %drop and %extend have been removed.
498    
499    We now allow optional type annotations on nonterminals, using the %nonterms
500    directive as in ml-yacc.
501    
502    The refcell construct is now implemented using SML's regular reference
503    cells, so the :== and !! notation has been deprecated.
504    
505    The ml-antlr tool now does much more checking of specifications, and
506    its error messages have been greatly improved.  Error repair for
507    generated parsers has been completely rewritten, and is now both
508    much faster and more accurate.
509    
510    ml-ulex is now more lenient with escape codes (non-SML-standard
511    escape codes are now interpreted literally, so e.g. \| denotes "|").
512    Also, character classes may now include a "-" character at the beginning
513    as is standard in most other regexp tools.
514    
515    All of these changes are documented in the user guide, which has
516    been updated and improved with this merge.

534    Preliminary commit of large ml-lpt revisions (more to come for 110.64).
535    The ml-antlr specification format has changed: declarations such as
536    %tokens and nonterminal definitions can occur *multiple* times in the
537    same specification.  The semantics are such that each new declaration
538    extends the previous ones.  Grammar extension constructs have also

540    the refcell construct is now implemented using SML's regular reference
541    cells, so the :== and !! notation has been deprecated.  All of these
542    changes will appear in the 110.64 user guide for ml-lpt.
543    
544    The ml-antlr tool now does much more checking of specifications, and
545    its error messages have been greatly improved.  There has also been
546    some work on the error repair process for generated parsers, but this
547    will be further improved in 110.64.

583    Description:
584    
585    More Basis fixes: The Char.fromString (etc.) functions did not handle
586    the "\uxxxx" escape sequence.  There is still an outstanding bug with
587    String.fromString the tail is a format escape.  I added a comment to
588    this effect in Basis/Implementation/string.sml.

627    Substantially changed the signature and implementation of AMD64
628    SVID.  It now looks similar to the ia32 SVID, yet uses staged
629    allocation.
