19    Description:
20    
21    Fixed IEEEReal.scan (and .fromString) so that if there is an overflow
22    in the exponent calculation we get INF or ZERO (depending on the mantissa
23    and the sign of the exponent).

40    Made exception Option to be the same as exception Option.Option
41    (as it should be).

46    Tag: leunga-20040319-cygwin-nlffi
47    Description:
48    
49    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
50    of SML/NJ.  The problem is that
51    
52       lib = dlopen(NULL, ...)
53       f   = dlsym(lib, "malloc");
54    
55    does not work on Windows unless we explicitly export symbols
56    such as 'malloc' during linking.  We fixed this by explicitly
57    exporting the required symbols with the magic gcc incantation:
58    
59        -Wl,--export-all cygwin.def
60    
61    where cygwin.def is a file containing all the symbols that
62    we wish to export.
63    
64    I suspect this is a Windows problem and we'll have to
65    do the same (somehow with windows compilers) when
66    we build the native win32 version with the system
67    calls LoadLibrary/GetProcAddress.

73    Description:
74

76    of on the left for BIN, OCT, and HEX).

82    Description:
83    
84    Fixed problem with installer script (unix only) where bin/ml-yacc and
85    friends pointed (via symlinks) to absolute locations instead of just
86    .run-sml.  This was reported by Vesa A Norrman.

134    Tag: blume-20031104-move-libraries
135    Description:
136    
137    Eliminated the "dont_move_libraries" directive in config/targets.
138    (The mechanism was broken and could not be fixed easily.  Moreover,
139    there does not seem to be any reason not to move all libraries into
140    lib during installation.  I originally implemented this directive as a
141    backward-compatibility feature when I first introduced the new CM.
142    Now that things have been stable for a long time and going back to the
143    old CM is not an option, there is no reason to keep it around.)

192    Tag: blume-20030926-ppautoload
193    Description:
194    
195    I modified the read-eval-print loop so that the autoloader gets
196    invoked whenever the prettyprinter tries to look up a symbol that
197    is not currently defined in the toplevel environment but which
198    appears in CM's autoload registry.  As a result, we see far fewer of
199    those ?.Foo.Bar.xxx names in the prettyprinter's output.
200    
201    In addition to this I tried to clean up some pieces of the Basis
202    implementation (e.g., Socket, Word8Array) in order to prevent other
203    instances of these ?.Foo.Bar.xxx names from being printed.
204    
205    The mechanism that picks names for types still needs some work, though.
206    (Right now it seems that if there is a type A.t which is defined to
207    be B.u, but B is unavailable at toplevel, then A.t gets printed as
208    "?.B.u" although the perhaps more sensible solution would be to use
209    "A.t" in this case.  In other words, the prettyprinter should follow
210    a chain of DEFtycs not farther than there are corresponding toplevel
211    names in the current environment.)

216    Tag: blume-20030924-installer
217    Description:
218    
219    Another installer tweak:  All the ML code for the installer is now
220    compiled during CMB.make and put into a little library called
221    $smlnj/installer.cm.  The installation then simply invokes
222    
223       sml -m $smlnj/installer.cm
224    
225    and everything happens automagically.
226    
227    Win32:  ML code senses value of environment variable SMLNJ_HOME.
228    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
229            and BINDIR.
230    
231    The new scheme guarantees that the ML code responsible for the installation
232    is in sync with the APIs of the main system.  Also, the installer is
233    somewhat faster because the installer script is precompiled.

238    Tag: blume-20030924-synsock
239    Description:
240    
241    Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
242    but excludes all non-blocking operations.  Defined SOCKET (in Basis)
243    and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
244    implementations of non-blocking operations from CML's Socket
245    structure.

250    Tag: blume-20030924-sockets
251    Description:
252    
253    1. Fixed SOCKET API and implementation to match Basis spec.
254       This required changing the internal representation of sockets to one
255       that remembers (for each socket file descriptor) whether it is currently
256       blocking or non-blocking.  This state is maintained lazily (i.e., a system
257       call is made only if the state actually needs to change).
258    
259    2. OS-specific details of sockets were moved into separate files, thus
260       making it possible to unify the bulk of the socket implementations
261       between Unix and Win32.
262    
263    3. CML's socket API changed accordingly.
264       (Note that we need to remove non-blocking functions from this API
265       since they are redundant in the case of CML!)
266    
267    4. CML's socket implementation now makes use of non-blocking functions
268       provided by Basis, thus removing all OS-dependent code from this part
269       of CML.
270    
271    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

288    Description:
289    
290    1. new-install.sh -> install.sh
291    2. changed default CM "metadata" directory name to ".cm" (instead of "CM")
292    3. tweaked installer so that another name instead of .cm can be chosen
293       at install time (by setting the CM_DIR_ARC environment variable
294       during installation); once installation is complete, the name is
295       fixed

314    1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as

316       Posix.ProcEnv.times.
317    
318    2. Added Time.{from,to}Nanoseconds to Time.
319    
320    3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
321       For example, fromLargeInt never needs to look at more than 3 "big
322       digits" to get its 53 bits of precision.

329    
330    Added an entry to the primitive environment
331    (compiler/Semant/statenv/prim.sml) for int32->real64 conversion and
332    added code to compiler/CodeGen/main/mlriscGen.sml to implement it.
333    
334    Removed some of the "magic" constants in real64.sml and replaced them
335    with code that generates these values from their corresponding
336    integer counterparts.
337    
338    Made all(?) the slice-related changes to the Basis and made everything

384    Description:
385    
386    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
387    Modified config/install.bat to take advantage of it.  Also modified
388    config/install.sh (and called it config/new-install.sh) to take advantage
389    of it on Unix systems.  (The SML code is (supposed to be) platform-
390    independent.)
391    
392    The installer can now install everything under Win32
393    as well as under *nix as long as it compiles.
394    
395    Other changes:
396    
397      - made CML compile again under Win32
398      - made eXene compile under Win32 (by providing a fake structure UnixSock
399        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
400      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
401        same as type int;  under Win32 it isn't
402      - fixed some slice-related problems in the win32-specific parts of CML
403      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
404        (under Win32, the volume name is case-insensitive, and the
405        OS.Path code compares volume names for equality)

414    when given an empty string.  This is what the spec says, and incidentally,
415    CM depends on it.  (CM otherwise goes into an infinite loop in certain
416    cases when presented with the name of a non-existing .cm file.)

421    Tag: blume-20030905-slices-etc
422    Description:
423    
424      1. Changed interface to vectors and arrays in Basis to match
425         (draft) Basis spec.
426      2. Added signatures and implementations of slices according to
427         Basis spec.
428      3. Edited source code throughout the system to make it compile again
429         under 1. and 2.  (In some cases code had to be added to have it
430         match the new signatures.)
431      4. MLRISC should be backward-compatible: the copies of the originals
432         of files that needed to change under 3. were retained, the .cm files
433         check the compiler version number and use old versions when
434         appropriate.
435      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
436         dirstream -> string option (in accordance with Basis spec).
437      6. When generating code that counts lines, ml-lex used function
438         CharVector.foldli, taking advantage of its old interface.
439         This has been replaced with the corresponding code from
440         CharVectorSlice.  (html-lex must be re-lexed!)
441      7. BitArray in smlnj-lib/Util has been extended/modified to match the
442         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
443      8. Removed temporary additions (fromInternal, toInternal) from the
444         (now obsolete) IntInf in smlnj-lib/Util.
445      9. Cleaned up structure Byte.
446     10. Added localOffset, scan, and fromString to Date (according to spec).
447         Cleaned/corrected implementation of Date.
448         (Still need to check for correctness; implement better canonicalizeDate.)
449     11. Added "scan" to signature IEEE_REAL.
450     12. Some improvements to IntInf [in particular: efficiency-hack for
451         mod and rem when second operand is 2 (for parity checks).]
452     13. Changed representation of type Time.time, using a single IntInf.int
453         value counting microseconds.  This considerably simplified the
454         implementation of structure Time.  We now support negative time
455         values; scan and fromString handle signs.
456     14. Functor PrimIO now takes two additional arguments (VectorSlice and
457         ArraySlice).

463    Description:
464    
465    This is a major update which comes with a version number bump
466    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
467    and an implementation of IntInf in the Basis.
468    
469    There are a fairly large number of related changes and updates throughout
470    the system:
471    
472    Basis:
473            - Implemented IntInf.
474            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
475            - Added some missing Real64 operations, most notably Real.toLargeInt.
476            - Added FixedInt as a synonym for Int32.
477    
478    compiler:
479            * Added support for a built-in intinf type.
480              - literals
481              - pattern matching
482              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
483              - overloading on literals and operations
484    
485            This required adding a primitive type intinf, some additional
486            primops, and implementations for several non-trivial intinf
487            operations in Core.  (The intinf type is completely abstract
488            to the compiler; all operations get delegated back to the Core.)
489    
490            * Intinf equality is handled by polyequal.  However, the compiler
491            does not print its usual warning in this case (since polyequal
492            is the right thing to do there).
493    
494            * Improved the organization of structure InlineT.
495    
496            * A word about conversion primops:
497            If conversions involving intinf do not cancel out during
498            CPS contract, then the compiler must insert calls to Core functions.
499            Since all core access must be resolved already during the FLINT
500            translate phase, it would be too late a the time of CPS contract
501            to add new Core calls.  For this reason, conversion primops
502            for intinf carry two arguments:  1. the numeric argument that
503            they are supposed to convert, and 2. the Core function that
504            can help with this conversion if necessary.  If CPS contract
505            eliminates a primop, then the associated Core function becomes
506            dead and goes away.  Intinf conversion primops that do not get
507            eliminated by CPS contract get rewritten into calls of their
508            core functions by a separate, new phase.
509    
510    interactive system:
511            - Control.Print.intinfDepth controls max length of intinf constants
512            being printed. (Analogous to Control.Print.stringDepth.)
513            - Cleanup in printutil and pputil: got rid of unused stuff and
514            duplicates; replaced some of the code with code that makes better
515            use of library functionality.
516    
517    CM:
518            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
519            are no longer silent.
520    
521    CKIT:
522            Fixed mismatched uses of Int32 and LargeInt.  I always decided
523            in favor of LargeInt -- which is now the same as IntInf.
524            CKIT-knowledgable people should check whether this is what's
525            intended and otherwise change things back to using Int32 or
526            FixedInt.
527    
528    Throughout the code:
529            Started using IntInf.int literals and built-in operations
530            (e.g., comparison with 0) where this seems appropriate.

539    Merging changes from the mcz-branch development branch into trunk.
540    These changes involve replacement of the emulated old prettyprinter
541    interface with direct use of the SML/NJ Lib PP library, and fixing
542    of a couple of bugs (895, 1186) relating to error messages.  A new
543    prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
544    has been added.

550    Description:
551    
552    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
553    
554        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
555    
556    This patch restores SML/NJ's ability to run under win32.  There are a
557    number of changes, including fixes for several bugs that had gone
558    unnoticed until now:
559    
560      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
561        trying to run the win32 version from within cygwin.)
562    
563      - There are a number of simple .bat scripts that substitute for their
564        corresponding Unix shell-scripts.  (See below.)
565    
566      - The internals of ml-build have been modified slightly.  The main
567        difference is that instead of calling ".link-sml" (or link-sml.bat)
568        using OS.Process.system, the ML process delegates this task back
569        to the script.  Otherwise problems arise in mixed environments such
570        as Cygwin where scripts look and work like Unix scripts, but
571        where OS.Process.system cannot run them.
572    
573      - In CM, the srcpath pickler used native pathname syntax -- which
574        is incorrect in the case of cross-compilation.  The new pickle format
575        is independent of platform-specific naming conventions.
576    
577      - Path configuration files (such as lib/pathconfig) can now choose
578        between native and standard syntax.  Placing a line of the form
579    
580            standard!
581    
582        into the file causes all subsequent paths to be interpreted using
583        CM standard pathname syntax (= Unix conventions); a line
584    
585            native!
586    
587        switches back to native style.  This was needed so that
588        path config files can be written portably, see src/system/pathconfig.
589    
590      - Runtime system:
591    
592          - win32-filesys.c:  get_file_time and set_file_time now
593            access modification time, not creation time.
594    
595          - I/O code made aware of new array representation.
596    
597          - Bug fixes in X86.prim.masm.
598    
599       - src/system/makeml made aware of win32. (For use under cygwin
600            and other Unix-environments for windows.)
601    
602       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
603         which caused BinIO.inputAll to fail consistently.
604    
605    .bat scripts:
606    
607       Windows .bat scripts assume that SMLNJ_HOME is defined.
608    
609       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
610         applications (sml, ml-yacc, ml-lex).
611       - ml-build.bat: analogous to ml-build.
612       - config\install.bat:  Analogous to config/install.sh.  This requires
613         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
614         (nmake etc. must be on the path, and vcvars32 must have been run.)
615         Moreover, sources for ml-lex and ml-yacc need to exist under src,
616         and the bootfile hierarchy must have been unpacked under
617         sml.boot.x86-win32.
618         The script is very primitive and does a poor job at error checking.
619         It only installs the base system, ml-lex, and ml-yacc.  No other
620         libraries are being installed (i.e., you get only those that
621         are part of the compiler.)
622       - link-sml.bat:  analogous to .link-sml, but not currently used
623    
624    Unrelated bug fixes:
625    
626      - ml-nlffigen now exports structures ST_* corresponding to incomplete
627        types.
628      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
629        otherwise.)

654    
655    Two changes:
656    
657      1. Added a flag for controlling whether non-exhaustive bindings will
658         be treated as errors (default is false).
659      2. Cleaned up the *entire* source tree so that CMB.make goes through
660         without a single non-exhaustive match- or bind warning.

666    Description:
667    
668    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
669    
670       This mainly affects the quality of error messages.  However, some
671       of the code is now more straightforward than before. (Treatment of
672       the above four constructs in translate.sml is much simpler than
673       the "macro-expansion" that was going on before.  Plus, the mach-
674       compiler no longer gets invoked just to be able to compile an
675       if-expression.)
676    
677    2. The ErrorMsg.Error exception is now caught and absorbed by the
678       interactive loop.

684    Description:
685    
686        Ported the runtime system to cygwin, which uses the unix
687    x86-unix bin files.  Missing/buggy features:
688    
689       o getnetbyname, getnetbyaddr: these functions seem to be missing in
690         the Cygwin library.
691       o Ctrl-C handling may be flaky.
692       o Windows system calls and Windows I/O are not supported.
693    
694       A new set of binfiles is located at:
695    
696         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
697    
698       This is only needed for bootstrapping the cygwin version of smlnj.
699       Other x86 versions can use the existing binfiles.
