19    Description:
20    
21    Added C_UNION to c-calls/c-types.sml and updated the machinery
22    (ml-nlffigen, cproto.sml) that conveys C function interface
23    information to the code generator.
24    
25    However, the actual architecture-specific implementation of function
26    arguments and results that are C unions is still not implemented.

34        Added these instructions to the PowerPC architecture:
35        LBZU(X), LHZU(X), LWZU(X),
36        STWU(X), STFDU, STFSU
37    
38        etc...
39    
40        Note: I haven't added their instruction encoding into the description.

47    
48       Added the two instructions LWARX and STWCX to the PowerPC
49    instruction set.
50    
51       A (untested) rewrite of loop-structure.sml.  The old version

57    Tag: blume-20040713-nlffi
58    Description:
59    
60    - use paramAlloc to report c-calls with too many arguments
61      (for PPC version where parameter area is pre-allocated)
62    - added ccall_maxargspace to machspec (to implement the above)
63    - made "make" commend in CM's "make" tool configurable
64    - added option (default: on) for passing the name of the SML/NJ's "bin"
65      directory to "make"; the call looks like this:
66    
67         make <options> SMLNJ_BINDIR=<dir> <target>
68    
69      This can be used by the Makefile to, e.g., pick the "right" version
70      of ml-nlffigen.
71    - minor code tweaks

76    Tag: blume-110_46_1-macosx-nlffi
77    Description:
78    
79    NLFFI under Mac OS X now working (sort of).  This is largely untested,
80    though.
81    
82    Note:  1. You have to make a new, clean build of the runtime system.
83           2. There are new BOOTFILES, you have to use them!
84              (Doing the bootstrap process yourself would be *very* painful!
85               If you absolutely have to do it, build the system under
86               a different architecture and then cross-compile.)
87    
88    Version bumped to 110.46.1 to account for runtime data format changes.

93    Tag: blume-20040618-unix
94    Description:
95    
96    Changed the implementation of structure Unix so that the same stream
97    is returned every time one of the {text,bin}{In,Out}streamOf functions
98    is invoked on the same proc.  This is not what the spec currently
99    says -- although IMO it arguably should.  (See discussion below.)

112    Tag: blume-20040617-timer-unix
113    Description:
114    
115    Changed the interface of structures Timer and Unix to match the most
116    recent Basis spec.
117    
118    In the case of Unix there still seems to be an open/weird issue:
119    
120       The {text,bin}{In,Out}streamOf functions are supposed to create
121       fresh streams whenever they are called -- as opposed to have them
122       return the same stream every time.  This design is supposed to
123       prevent space leaks caused by proc values hanging on to streams.
124    
125       The reap function, on the other hand, is supposed to close the
126       streams.  This cannot be done without having a handle on the
127       stream in proc after all...
128    
129    I took the liberty to implement the following stopgap solution:
130    
131      The proc value hangs on to the most recently created stream(s).
132      Reap closes those.  If either or both of the two streams hadn't
133      been created at all yet, then reap will close the corresponding
134      file descriptors directly.
135    
136    PS: I don't understand the original space leak argument anymore.  If
137    a proc hangs on to the imperative stream, then I/O operations on those
138    will advance the state of the cached stream and avoid the space leak.

151    Tag: blume-20040525-group-owner
152    Description:
153    
154    CM now ignores (but still accepts) the "owner" information in group
155    descriptions.  The owner of a group is its next enclosing
156    library. Each group must have a unique owner.  (There is a virtual
157    "toplevel" library that owns groups which are not nested within a real
158    library.)  Previously, each group had to explicitly declare its owner,
159    and CM would check that such a declaration is correct.  The new scheme
160    is to have CM check that for each group there is precisely one owning
161    library.
162    
163    The advantage of the new scheme is that the programmer no longer needs
164    to maintain the somewhat annoying owner information.  The downside is
165    that CM cannot enforce the ownership rule across multiple runs of
166    CM.make.  Fortunately, enclosing the same group in two different
167    libraries A and B which are not part of the same program does not
168    cause real problems.

173    Tag: blume-20040520-win32
174    Description:
175    
176    Made the win32 version work again.  (Strangely, a misplaced comma had
177    slipped into win32-process.c which prevented the runtime from being
178    compiled correctly.)
179    
180    Also, included a minor addition to ml-build.bat analogous to what was
181    done in blume-20040519-ml-build.

186    Tag: blume-20040519-ml-build
187    Description:
188    
189    Arranged for ml-build to clean up after itself a little bit better.
190    The script generates a temporary SML source file and compiles it using
191    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
192    gets rid of those at the end, so they don't accumulate under .cm.
193    
194    This required a minor change to install.sh because the name of the
195    metadata directory (default: .cm) is actually configurable at
196    installation time.

210    Tag: blume-20040511-win32sock
211    Description:
212    
213    Added previously missing support for many socket-related functions
214    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
215    for the voluminous patch!
216    
217    (I have not tested this patch under win32 yet.)
218    
219    Here is David's e-mail:
220    
221    Hi,
222    
223    Attached to this email you find a diff against sml/nj 110.45
224    that will enable socket support under Windows.
225    
226    To apply the patch (using unix or cygwin)
227    1) gunzip runtime.diff.gz
228    2) "cd" into "src/runtime" in the source tree of a fresh
229       110.45 installation.
230    3) patch -p 1 < [your/path/to]runtime.diff
231    
232    The code compiles fine but has NOT yet been extensively tested.
233    I only ran a few tests for basic socket client functionality
234    (which worked fine).  Especially the functions that use ioctl
235    are not tested at all and might not work (see below).
236    
237    I implemented this since we want to move to a newer version of sml/nj
238    but need socket support in order to use it.  This is the first time I
239    even had a look at the sml/nj source,  so please review my changes
240    before making this part of the distribution!  Here are a few issues
241    that I think might be better for someone to solve who is more
242    familiar with the sml/nj source (and socket programming):
243    
244    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
245      exception since I could not figure out what the windows equivalent
246      of these functions is
247    
248    - In sockets-osdep.h there are a some #include statements that are
249      only used in a few files that include sockets-osdep.h
250    
251    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
252      does not process its return value since I don't know how to
253      report an error upwards.
254    
255    - It would probably be good to have a call to WSACleanup() when
256      the library is unloaded (if there is such a possibility).
257      Otherwise I think Windows will take care of this automatically
258      when the process finishes.
259    
260    - I used ioctlsocket() as a replacement for ioctl() but I have
261      no idea if that is actually the proper replacement on Windows.
262    
263    - All these issues are marked in the code by "FIXME" comments.
264    
265    We use sml/nj extensively in our products and are quite happy
266    with it.  I hope this contribution will help you.
267    
268    Keep up the good work!
269

303    Description:
304    
305    The installer now honors the "src-smlnj" target again, although its meaning
306    has changed from "all sources required for the compiler" to "all sources
307    the installer knows about".  In other words, if you enable "src-smlnj"
308    in the "targets" file, then the installer will pull in sources for
309    everything.  (Notice that this refers to source code only.  Compiled
310    code is still only installed for modules that were requested explicitly
311    or which are required for other modules that were requested explicitly.)

344    Tag: leunga-20040319-cygwin-nlffi
345    Description:
346    
347    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
348    of SML/NJ.  The problem is that
349    
350       lib = dlopen(NULL, ...)
351       f   = dlsym(lib, "malloc");
352    
353    does not work on Windows unless we explicitly export symbols
354    such as 'malloc' during linking.  We fixed this by explicitly
355    exporting the required symbols with the magic gcc incantation:
356    
357        -Wl,--export-all cygwin.def
358    
359    where cygwin.def is a file containing all the symbols that
360    we wish to export.
361    
362    I suspect this is a Windows problem and we'll have to
363    do the same (somehow with windows compilers) when
364    we build the native win32 version with the system
365    calls LoadLibrary/GetProcAddress.

434    
435    Eliminated the "dont_move_libraries" directive in config/targets.
436    (The mechanism was broken and could not be fixed easily.  Moreover,
437    there does not seem to be any reason not to move all libraries into
438    lib during installation.  I originally implemented this directive as a
439    backward-compatibility feature when I first introduced the new CM.
440    Now that things have been stable for a long time and going back to the
441    old CM is not an option, there is no reason to keep it around.)

491    Description:
492    
493    I modified the read-eval-print loop so that the autoloader gets
494    invoked whenever the prettyprinter tries to look up a symbol that
495    is not currently defined in the toplevel environment but which
496    appears in CM's autoload registry.  As a result, we see far fewer of
497    those ?.Foo.Bar.xxx names in the prettyprinter's output.
498    
499    In addition to this I tried to clean up some pieces of the Basis
500    implementation (e.g., Socket, Word8Array) in order to prevent other
501    instances of these ?.Foo.Bar.xxx names from being printed.
502    
503    The mechanism that picks names for types still needs some work, though.
504    (Right now it seems that if there is a type A.t which is defined to
505    be B.u, but B is unavailable at toplevel, then A.t gets printed as
506    "?.B.u" although the perhaps more sensible solution would be to use
507    "A.t" in this case.  In other words, the prettyprinter should follow
508    a chain of DEFtycs not farther than there are corresponding toplevel
509    names in the current environment.)

515    Description:
516    
517    Another installer tweak:  All the ML code for the installer is now
518    compiled during CMB.make and put into a little library called
519    $smlnj/installer.cm.  The installation then simply invokes
520    
521       sml -m $smlnj/installer.cm
522    
523    and everything happens automagically.
524    
525    Win32:  ML code senses value of environment variable SMLNJ_HOME.
526    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
527            and BINDIR.
528    
529    The new scheme guarantees that the ML code responsible for the installation
530    is in sync with the APIs of the main system.  Also, the installer is
531    somewhat faster because the installer script is precompiled.

537    Description:
538    
539    Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
540    but excludes all non-blocking operations.  Defined SOCKET (in Basis)
541    and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
542    implementations of non-blocking operations from CML's Socket
543    structure.

549    Description:
550    
551    1. Fixed SOCKET API and implementation to match Basis spec.
552       This required changing the internal representation of sockets to one
553       that remembers (for each socket file descriptor) whether it is currently
554       blocking or non-blocking.  This state is maintained lazily (i.e., a system
555       call is made only if the state actually needs to change).
556    
557    2. OS-specific details of sockets were moved into separate files, thus
558       making it possible to unify the bulk of the socket implementations
559       between Unix and Win32.
560    
561    3. CML's socket API changed accordingly.
562       (Note that we need to remove non-blocking functions from this API
563       since they are redundant in the case of CML!)
564    
565    4. CML's socket implementation now makes use of non-blocking functions
566       provided by Basis, thus removing all OS-dependent code from this part
567       of CML.
568    
569    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

616    2. Added Time.{from,to}Nanoseconds to Time.
617    
618    3. Improved Real.{from,to}LargeInt by avoiding needless calculations.

682    Description:
683    
684    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
685    Modified config/install.bat to take advantage of it.  Also modified
686    config/install.sh (and called it config/new-install.sh) to take advantage
687    of it on Unix systems.  (The SML code is (supposed to be) platform-
688    independent.)
689    
690    The installer can now install everything under Win32
691    as well as under *nix as long as it compiles.
692    
693    Other changes:
694    
695      - made CML compile again under Win32
696      - made eXene compile under Win32 (by providing a fake structure UnixSock
697        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
698      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
699        same as type int;  under Win32 it isn't
700      - fixed some slice-related problems in the win32-specific parts of CML
701      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
702        (under Win32, the volume name is case-insensitive, and the
703        OS.Path code compares volume names for equality)

720    Description:
721    
722      1. Changed interface to vectors and arrays in Basis to match
723         (draft) Basis spec.
724      2. Added signatures and implementations of slices according to
725         Basis spec.
726      3. Edited source code throughout the system to make it compile again
727         under 1. and 2.  (In some cases code had to be added to have it
728         match the new signatures.)
729      4. MLRISC should be backward-compatible: the copies of the originals
730         of files that needed to change under 3. were retained, the .cm files
731         check the compiler version number and use old versions when
732         appropriate.
733      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
734         dirstream -> string option (in accordance with Basis spec).
735      6. When generating code that counts lines, ml-lex used function
736         CharVector.foldli, taking advantage of its old interface.
737         This has been replaced with the corresponding code from
738         CharVectorSlice.  (html-lex must be re-lexed!)
739      7. BitArray in smlnj-lib/Util has been extended/modified to match the
740         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
741      8. Removed temporary additions (fromInternal, toInternal) from the
742         (now obsolete) IntInf in smlnj-lib/Util.
743      9. Cleaned up structure Byte.
744     10. Added localOffset, scan, and fromString to Date (according to spec).
745         Cleaned/corrected implementation of Date.
746         (Still need to check for correctness; implement better canonicalizeDate.)
747     11. Added "scan" to signature IEEE_REAL.
748     12. Some improvements to IntInf [in particular: efficiency-hack for
749         mod and rem when second operand is 2 (for parity checks).]
750     13. Changed representation of type Time.time, using a single IntInf.int
751         value counting microseconds.  This considerably simplified the
752         implementation of structure Time.  We now support negative time
753         values; scan and fromString handle signs.
754     14. Functor PrimIO now takes two additional arguments (VectorSlice and
755         ArraySlice).

760    Tag: blume-20030828-intinf
761    Description:
762    
763    This is a major update which comes with a version number bump
764    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
765    and an implementation of IntInf in the Basis.
766    
767    There are a fairly large number of related changes and updates throughout
768    the system:
769    
770    Basis:
771            - Implemented IntInf.
772            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
773            - Added some missing Real64 operations, most notably Real.toLargeInt.
774            - Added FixedInt as a synonym for Int32.
775    
776    compiler:
777            * Added support for a built-in intinf type.
778              - literals
779              - pattern matching
780              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
781              - overloading on literals and operations
782    
783            This required adding a primitive type intinf, some additional
784            primops, and implementations for several non-trivial intinf
785            operations in Core.  (The intinf type is completely abstract
786            to the compiler; all operations get delegated back to the Core.)
787    
788            * Intinf equality is handled by polyequal.  However, the compiler
789            does not print its usual warning in this case (since polyequal
790            is the right thing to do there).
791    
792            * Improved the organization of structure InlineT.
793    
794            * A word about conversion primops:
795            If conversions involving intinf do not cancel out during
796            CPS contract, then the compiler must insert calls to Core functions.
797            Since all core access must be resolved already during the FLINT
798            translate phase, it would be too late a the time of CPS contract
799            to add new Core calls.  For this reason, conversion primops
800            for intinf carry two arguments:  1. the numeric argument that
801            they are supposed to convert, and 2. the Core function that
802            can help with this conversion if necessary.  If CPS contract
803            eliminates a primop, then the associated Core function becomes
804            dead and goes away.  Intinf conversion primops that do not get
805            eliminated by CPS contract get rewritten into calls of their
806            core functions by a separate, new phase.
807    
808    interactive system:
809            - Control.Print.intinfDepth controls max length of intinf constants
810            being printed. (Analogous to Control.Print.stringDepth.)
811            - Cleanup in printutil and pputil: got rid of unused stuff and
812            duplicates; replaced some of the code with code that makes better
813            use of library functionality.
814    
815    CM:
816            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
817            are no longer silent.
818    
819    CKIT:
820            Fixed mismatched uses of Int32 and LargeInt.  I always decided
821            in favor of LargeInt -- which is now the same as IntInf.
822            CKIT-knowledgable people should check whether this is what's
823            intended and otherwise change things back to using Int32 or
824            FixedInt.
825    
826    Throughout the code:
827            Started using IntInf.int literals and built-in operations
828            (e.g., comparison with 0) where this seems appropriate.

849    
850    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
851    
852        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
853    
854    This patch restores SML/NJ's ability to run under win32.  There are a
855    number of changes, including fixes for several bugs that had gone
856    unnoticed until now:
857    
858      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
859        trying to run the win32 version from within cygwin.)
860    
861      - There are a number of simple .bat scripts that substitute for their
862        corresponding Unix shell-scripts.  (See below.)
863    
864      - The internals of ml-build have been modified slightly.  The main
865        difference is that instead of calling ".link-sml" (or link-sml.bat)
866        using OS.Process.system, the ML process delegates this task back
867        to the script.  Otherwise problems arise in mixed environments such
868        as Cygwin where scripts look and work like Unix scripts, but
869        where OS.Process.system cannot run them.
870    
871      - In CM, the srcpath pickler used native pathname syntax -- which
872        is incorrect in the case of cross-compilation.  The new pickle format
873        is independent of platform-specific naming conventions.
874    
875      - Path configuration files (such as lib/pathconfig) can now choose
876        between native and standard syntax.  Placing a line of the form
877    
878            standard!
879    
880        into the file causes all subsequent paths to be interpreted using
881        CM standard pathname syntax (= Unix conventions); a line
882    
883            native!
884    
885        switches back to native style.  This was needed so that
886        path config files can be written portably, see src/system/pathconfig.
887    
888      - Runtime system:
889    
890          - win32-filesys.c:  get_file_time and set_file_time now
891            access modification time, not creation time.
892    
893          - I/O code made aware of new array representation.
894    
895          - Bug fixes in X86.prim.masm.
896    
897       - src/system/makeml made aware of win32. (For use under cygwin
898            and other Unix-environments for windows.)
899    
900       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
901         which caused BinIO.inputAll to fail consistently.
902    
903    .bat scripts:
904    
905       Windows .bat scripts assume that SMLNJ_HOME is defined.
906    
907       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
908         applications (sml, ml-yacc, ml-lex).
909       - ml-build.bat: analogous to ml-build.
910       - config\install.bat:  Analogous to config/install.sh.  This requires
911         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
912         (nmake etc. must be on the path, and vcvars32 must have been run.)
913         Moreover, sources for ml-lex and ml-yacc need to exist under src,
914         and the bootfile hierarchy must have been unpacked under
915         sml.boot.x86-win32.
916         The script is very primitive and does a poor job at error checking.
917         It only installs the base system, ml-lex, and ml-yacc.  No other
918         libraries are being installed (i.e., you get only those that
919         are part of the compiler.)
920       - link-sml.bat:  analogous to .link-sml, but not currently used
921    
922    Unrelated bug fixes:
923    
924      - ml-nlffigen now exports structures ST_* corresponding to incomplete
925        types.
926      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
927        otherwise.)

951    Description:
952    
953    Two changes:
954    
955      1. Added a flag for controlling whether non-exhaustive bindings will
956         be treated as errors (default is false).
957      2. Cleaned up the *entire* source tree so that CMB.make goes through
958         without a single non-exhaustive match- or bind warning.

963    Tag: blume-20030517-absyn
964    Description:
965    
966    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
967    
968       This mainly affects the quality of error messages.  However, some
969       of the code is now more straightforward than before. (Treatment of
970       the above four constructs in translate.sml is much simpler than
971       the "macro-expansion" that was going on before.  Plus, the mach-
972       compiler no longer gets invoked just to be able to compile an
973       if-expression.)
974    
975    2. The ErrorMsg.Error exception is now caught and absorbed by the
976       interactive loop.

982    Description:
983    
984        Ported the runtime system to cygwin, which uses the unix
985    x86-unix bin files.  Missing/buggy features:
986    
987       o getnetbyname, getnetbyaddr: these functions seem to be missing in
988         the Cygwin library.
989       o Ctrl-C handling may be flaky.
990       o Windows system calls and Windows I/O are not supported.
991    
992       A new set of binfiles is located at:
993    
994         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
995    
996       This is only needed for bootstrapping the cygwin version of smlnj.
997       Other x86 versions can use the existing binfiles.

1022    Description:
1023    
1024    Fixed a serious bug in the rewrite code for FP spilling/reloading that
1025    sent the RA into an infinite loop when floating point registers get
1026    spilled.  (Because of this bug, e.g., nucleic stopped compiling between
1027    110.37 and 110.38.)
1028    There was another set of potential problems related to the handling of
1029    MLRISC annotations (but those did not yet cause real problems, apparently).

1035    Description:
1036    
1037    Added a call of SrcPath.sync at the beginning of Parse.parse (in CM).
1038    This fixes the problem of CM getting confused by files that suddenly
1039    change their identity (e.g., by getting unlinked and recreated by some
1040    text editor such as vi).  There might be a better/cheaper/cleaner way
1041    of doing this, but for now this will have to do.

1055    Description:
1056    
1057    In good old tradition, there has been a slight hiccup so that we have
1058    to patch 110.42 after the fact.   The old release tag has been replaced
1059    (see below).
1060    
1061    The change solves a problem with two competing approaches the
1062    configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
1063    each other's way.
1064    
1065    This change only affects the runtime system code and the installer script.
1066    (No new bootfiles.)

1084    well.
