19    Description:
20    
21    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
22    of SML/NJ.  The problem is that
23    
24       lib = dlopen(NULL, ...)
25       f   = dlsym(lib, "malloc");
26    
27    does not work on Windows unless we explicitly export symbols
28    such as 'malloc' during linking.  We fixed this by explicitly
29    exporting the required symbols with the magic gcc incantation:
30    
31        -Wl,--export-all cygwin.def
32    
33    where cygwin.def is a file containing all the symbols that
34    we wish to export.
35    
36    I suspect this is a Windows problem and we'll have to
37    do the same (somehow with windows compilers) when
38    we build the native win32 version with the system
39    calls LoadLibrary/GetProcAddress.

54    Description:
55    
56    Fixed problem with installer script (unix only) where bin/ml-yacc and
57    friends pointed (via symlinks) to absolute locations instead of just
58    .run-sml.  This was reported by Vesa A Norrman.

107    Description:
108    
109    Eliminated the "dont_move_libraries" directive in config/targets.
110    (The mechanism was broken and could not be fixed easily.  Moreover,
111    there does not seem to be any reason not to move all libraries into
112    lib during installation.  I originally implemented this directive as a
113    backward-compatibility feature when I first introduced the new CM.
114    Now that things have been stable for a long time and going back to the
115    old CM is not an option, there is no reason to keep it around.)

164    Tag: blume-20030926-ppautoload
165    Description:
166    
167    I modified the read-eval-print loop so that the autoloader gets
168    invoked whenever the prettyprinter tries to look up a symbol that
169    is not currently defined in the toplevel environment but which
170    appears in CM's autoload registry.  As a result, we see far fewer of
171    those ?.Foo.Bar.xxx names in the prettyprinter's output.
172    
173    In addition to this I tried to clean up some pieces of the Basis
174    implementation (e.g., Socket, Word8Array) in order to prevent other
175    instances of these ?.Foo.Bar.xxx names from being printed.
176    
177    The mechanism that picks names for types still needs some work, though.
178    (Right now it seems that if there is a type A.t which is defined to
179    be B.u, but B is unavailable at toplevel, then A.t gets printed as
180    "?.B.u" although the perhaps more sensible solution would be to use
181    "A.t" in this case.  In other words, the prettyprinter should follow
182    a chain of DEFtycs not farther than there are corresponding toplevel
183    names in the current environment.)

188    Tag: blume-20030924-installer
189    Description:
190    
191    Another installer tweak:  All the ML code for the installer is now
192    compiled during CMB.make and put into a little library called
193    $smlnj/installer.cm.  The installation then simply invokes
194    
195       sml -m $smlnj/installer.cm
196    
197    and everything happens automagically.
198    
199    Win32:  ML code senses value of environment variable SMLNJ_HOME.
200    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
201            and BINDIR.
202    
203    The new scheme guarantees that the ML code responsible for the installation
204    is in sync with the APIs of the main system.  Also, the installer is
205    somewhat faster because the installer script is precompiled.

210    Tag: blume-20030924-synsock
211    Description:
212    
213    Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
214    but excludes all non-blocking operations.  Defined SOCKET (in Basis)
215    and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
216    implementations of non-blocking operations from CML's Socket
217    structure.

222    Tag: blume-20030924-sockets
223    Description:
224    
225    1. Fixed SOCKET API and implementation to match Basis spec.
226       This required changing the internal representation of sockets to one
227       that remembers (for each socket file descriptor) whether it is currently
228       blocking or non-blocking.  This state is maintained lazily (i.e., a system
229       call is made only if the state actually needs to change).
230    
231    2. OS-specific details of sockets were moved into separate files, thus
232       making it possible to unify the bulk of the socket implementations
233       between Unix and Win32.
234    
235    3. CML's socket API changed accordingly.
236       (Note that we need to remove non-blocking functions from this API
237       since they are redundant in the case of CML!)
238    
239    4. CML's socket implementation now makes use of non-blocking functions
240       provided by Basis, thus removing all OS-dependent code from this part
241       of CML.
242    
243    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

260    Description:
261    
262    1. new-install.sh -> install.sh
263    2. changed default CM "metadata" directory name to ".cm" (instead of "CM")
264    3. tweaked installer so that another name instead of .cm can be chosen
265       at install time (by setting the CM_DIR_ARC environment variable
266       during installation); once installation is complete, the name is
267       fixed

286    1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
287       this seems to be controversial at the moment) and used those in
288       Posix.ProcEnv.times.
289    
290    2. Added Time.{from,to}Nanoseconds to Time.
291    
292    3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
293       For example, fromLargeInt never needs to look at more than 3 "big
294       digits" to get its 53 bits of precision.

301    
302    Added an entry to the primitive environment
303    (compiler/Semant/statenv/prim.sml) for int32->real64 conversion and
304    added code to compiler/CodeGen/main/mlriscGen.sml to implement it.
305    
306    Removed some of the "magic" constants in real64.sml and replaced them
307    with code that generates these values from their corresponding
308    integer counterparts.
309    
310    Made all(?) the slice-related changes to the Basis and made everything

356    Description:
357    
358    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
359    Modified config/install.bat to take advantage of it.  Also modified
360    config/install.sh (and called it config/new-install.sh) to take advantage
361    of it on Unix systems.  (The SML code is (supposed to be) platform-
362    independent.)
363    
364    The installer can now install everything under Win32
365    as well as under *nix as long as it compiles.
366    
367    Other changes:
368    
369      - made CML compile again under Win32
370      - made eXene compile under Win32 (by providing a fake structure UnixSock
371        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
372      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
373        same as type int;  under Win32 it isn't
374      - fixed some slice-related problems in the win32-specific parts of CML
375      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
376        (under Win32, the volume name is case-insensitive, and the
377        OS.Path code compares volume names for equality)

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

393    Tag: blume-20030905-slices-etc
394    Description:
395    
396      1. Changed interface to vectors and arrays in Basis to match
397         (draft) Basis spec.
398      2. Added signatures and implementations of slices according to
399         Basis spec.
400      3. Edited source code throughout the system to make it compile again
401         under 1. and 2.  (In some cases code had to be added to have it
402         match the new signatures.)
403      4. MLRISC should be backward-compatible: the copies of the originals
404         of files that needed to change under 3. were retained, the .cm files
405         check the compiler version number and use old versions when
406         appropriate.
407      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
408         dirstream -> string option (in accordance with Basis spec).
409      6. When generating code that counts lines, ml-lex used function
410         CharVector.foldli, taking advantage of its old interface.
411         This has been replaced with the corresponding code from
412         CharVectorSlice.  (html-lex must be re-lexed!)
413      7. BitArray in smlnj-lib/Util has been extended/modified to match the
414         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
415      8. Removed temporary additions (fromInternal, toInternal) from the
416         (now obsolete) IntInf in smlnj-lib/Util.
417      9. Cleaned up structure Byte.
418     10. Added localOffset, scan, and fromString to Date (according to spec).
419         Cleaned/corrected implementation of Date.
420         (Still need to check for correctness; implement better canonicalizeDate.)
421     11. Added "scan" to signature IEEE_REAL.
422     12. Some improvements to IntInf [in particular: efficiency-hack for
423         mod and rem when second operand is 2 (for parity checks).]
424     13. Changed representation of type Time.time, using a single IntInf.int
425         value counting microseconds.  This considerably simplified the
426         implementation of structure Time.  We now support negative time
427         values; scan and fromString handle signs.
428     14. Functor PrimIO now takes two additional arguments (VectorSlice and
429         ArraySlice).

435    Description:
436    
437    This is a major update which comes with a version number bump
438    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
439    and an implementation of IntInf in the Basis.
440    
441    There are a fairly large number of related changes and updates throughout
442    the system:
443    
444    Basis:
445            - Implemented IntInf.
446            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
447            - Added some missing Real64 operations, most notably Real.toLargeInt.
448            - Added FixedInt as a synonym for Int32.
449    
450    compiler:
451            * Added support for a built-in intinf type.
452              - literals
453              - pattern matching
454              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
455              - overloading on literals and operations
456    
457            This required adding a primitive type intinf, some additional
458            primops, and implementations for several non-trivial intinf
459            operations in Core.  (The intinf type is completely abstract
460            to the compiler; all operations get delegated back to the Core.)
461    
462            * Intinf equality is handled by polyequal.  However, the compiler
463            does not print its usual warning in this case (since polyequal
464            is the right thing to do there).
465    
466            * Improved the organization of structure InlineT.
467    
468            * A word about conversion primops:
469            If conversions involving intinf do not cancel out during
470            CPS contract, then the compiler must insert calls to Core functions.
471            Since all core access must be resolved already during the FLINT
472            translate phase, it would be too late a the time of CPS contract
473            to add new Core calls.  For this reason, conversion primops
474            for intinf carry two arguments:  1. the numeric argument that
475            they are supposed to convert, and 2. the Core function that
476            can help with this conversion if necessary.  If CPS contract
477            eliminates a primop, then the associated Core function becomes
478            dead and goes away.  Intinf conversion primops that do not get
479            eliminated by CPS contract get rewritten into calls of their
480            core functions by a separate, new phase.
481    
482    interactive system:
483            - Control.Print.intinfDepth controls max length of intinf constants
484            being printed. (Analogous to Control.Print.stringDepth.)
485            - Cleanup in printutil and pputil: got rid of unused stuff and
486            duplicates; replaced some of the code with code that makes better
487            use of library functionality.
488    
489    CM:
490            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
491            are no longer silent.
492    
493    CKIT:
494            Fixed mismatched uses of Int32 and LargeInt.  I always decided
495            in favor of LargeInt -- which is now the same as IntInf.
496            CKIT-knowledgable people should check whether this is what's
497            intended and otherwise change things back to using Int32 or
498            FixedInt.
499    
500    Throughout the code:
501            Started using IntInf.int literals and built-in operations
502            (e.g., comparison with 0) where this seems appropriate.

522    Description:
523    
524    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
525    
526        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
527    
528    This patch restores SML/NJ's ability to run under win32.  There are a
529    number of changes, including fixes for several bugs that had gone
530    unnoticed until now:
531    
532      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
533        trying to run the win32 version from within cygwin.)
534    
535      - There are a number of simple .bat scripts that substitute for their
536        corresponding Unix shell-scripts.  (See below.)
537    
538      - The internals of ml-build have been modified slightly.  The main
539        difference is that instead of calling ".link-sml" (or link-sml.bat)
540        using OS.Process.system, the ML process delegates this task back
541        to the script.  Otherwise problems arise in mixed environments such
542        as Cygwin where scripts look and work like Unix scripts, but
543        where OS.Process.system cannot run them.
544    
545      - In CM, the srcpath pickler used native pathname syntax -- which
546        is incorrect in the case of cross-compilation.  The new pickle format
547        is independent of platform-specific naming conventions.
548    
549      - Path configuration files (such as lib/pathconfig) can now choose
550        between native and standard syntax.  Placing a line of the form
551    
552            standard!
553    
554        into the file causes all subsequent paths to be interpreted using
555        CM standard pathname syntax (= Unix conventions); a line
556    
557            native!
558    
559        switches back to native style.  This was needed so that
560        path config files can be written portably, see src/system/pathconfig.
561    
562      - Runtime system:
563    
564          - win32-filesys.c:  get_file_time and set_file_time now
565            access modification time, not creation time.
566    
567          - I/O code made aware of new array representation.
568    
569          - Bug fixes in X86.prim.masm.
570    
571       - src/system/makeml made aware of win32. (For use under cygwin
572            and other Unix-environments for windows.)
573    
574       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
575         which caused BinIO.inputAll to fail consistently.
576    
577    .bat scripts:
578    
579       Windows .bat scripts assume that SMLNJ_HOME is defined.
580    
581       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
582         applications (sml, ml-yacc, ml-lex).
583       - ml-build.bat: analogous to ml-build.
584       - config\install.bat:  Analogous to config/install.sh.  This requires
585         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
586         (nmake etc. must be on the path, and vcvars32 must have been run.)
587         Moreover, sources for ml-lex and ml-yacc need to exist under src,
588         and the bootfile hierarchy must have been unpacked under
589         sml.boot.x86-win32.
590         The script is very primitive and does a poor job at error checking.
591         It only installs the base system, ml-lex, and ml-yacc.  No other
592         libraries are being installed (i.e., you get only those that
593         are part of the compiler.)
594       - link-sml.bat:  analogous to .link-sml, but not currently used
595    
596    Unrelated bug fixes:
597    
598      - ml-nlffigen now exports structures ST_* corresponding to incomplete
599        types.
600      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
601        otherwise.)

627    Two changes:

629      1. Added a flag for controlling whether non-exhaustive bindings will
630         be treated as errors (default is false).
631      2. Cleaned up the *entire* source tree so that CMB.make goes through
632         without a single non-exhaustive match- or bind warning.

638    Description:
639    
640    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
641    
642       This mainly affects the quality of error messages.  However, some
643       of the code is now more straightforward than before. (Treatment of
644       the above four constructs in translate.sml is much simpler than
645       the "macro-expansion" that was going on before.  Plus, the mach-
646       compiler no longer gets invoked just to be able to compile an
647       if-expression.)
648    
649    2. The ErrorMsg.Error exception is now caught and absorbed by the
650       interactive loop.

656    Description:
657    
658        Ported the runtime system to cygwin, which uses the unix
659    x86-unix bin files.  Missing/buggy features:
660    
661       o getnetbyname, getnetbyaddr: these functions seem to be missing in
662         the Cygwin library.
663       o Ctrl-C handling may be flaky.
664       o Windows system calls and Windows I/O are not supported.
665    
666       A new set of binfiles is located at:
667    
668         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
669    
670       This is only needed for bootstrapping the cygwin version of smlnj.
671       Other x86 versions can use the existing binfiles.

701    110.37 and 110.38.)
702    There was another set of potential problems related to the handling of
703    MLRISC annotations (but those did not yet cause real problems, apparently).

730    
731    In good old tradition, there has been a slight hiccup so that we have

733    (see below).
734    
735    The change solves a problem with two competing approaches the
736    configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
737    each other's way.
738    
739    This change only affects the runtime system code and the installer script.

770    the entire tree to some other place and everything will "just work".

922    o Made the mdl tool stuff compile and run again.
923    o I've disabled all the stuff that depends on RTL specifications; they
924      are all badly broken anyway.

930    Description:
931    
932    0. John Reppy made several modifications to the SML/NJ library.
933       In particular, there is a shiny new controls-lib.cm.
934    
935    1. Pushed new controls interface through compiler so that everything
936       compiles again.
937    
938    2. Added FormatComb and FORMAT_COMB to the CML version of the
939       SML/NJ library (so that CML compiles again).
940    
941    3. Modified init scripts because XXX_DEFAULT environment variables
942       are no longer with us.  (Boot-time initialization is now done
943       using the same environment variables that are also used for
944       startup-time initialization of controls.)

950    Description:
951    
952            All pseudo-ops emitted before the first segment declaration
953    such as TEXT, DATA, and BSS directives are assumed to be global
954    declarations and are emitted first in the assembly file. This is
955    useful in a number of situations where one has pseudo-ops that are not
956    specific to any segment, and also works around the constraint that one
957    cannot have client pseudo-ops in the TEXT segment.
958    
959            Because no segment is associated with these declarations it is
960    an error to allocate any space or objects before the first segment
961    directive and an exception will be raised. However, we cannot make
962    this check for client pseudo-ops.
963    
964            These top level declarations are a field in the CFG graph_info.
965    In theory you can continue to add to this field after the CFG has been
966    built -- provided you know what you are doing;-)
