19    Description:
20    
21    Put target "mlrisc" back into the default list.
22    (There is no harm in having it, and some users have expressed their
23    wish to have "mlrisc" included by default.)

40    Bumped the heap macig number to 0x09082004 to account for the changed
41    layout of the ML frame under MacOS X.

47    Description:
48    
49       Added a patch to _arch-n-opsys to enable the Cygwin runtime.
50    The Cygwin runtime is turned on by setting the environment
51    variable SMLNJ_CYGWIN_RUNTIME to 1.

65    Description:
66    
67    Upon request by Johannes Joemann:
68    
69    - improved ML code of installer to fall back to coping when renaming
70      fails (i.e., when source and target are on different file systems);
71      the code compiles but has yet to be tested in anger
72    - removed mlrisc from list of default targets (config/targets)

120    Description:
121    
122    Bug fix from Carl Hauser:
123    
124    single_source_shortest_paths in dijkstra.sml was observed to get wrong
125    answers (by comparing to single_source_shortest_paths in bellman-ford.sml).
126    
127    The problem is that following the expression A.update(dist,s,Num.zero)
128    it is necessary to update the priority queue using Q.decreaseWeight(Q,s).

133    Tag: blume-20040806-cmdline
134    Description:
135    
136    Fiddled with handling of command-line options:
137    
138      * sml now quits after processing the command line
139        if -H, -S, -h<n>, or -s<n> appears as the last
140        command-line argument
141      * a new option -q terminates the session when encountered on
142        the command line; subsequent arguments will be ignored
143      * bug fixes: short (erroneous) arguments are no longer ignored
144        completely

150    Description:
151    
152      - Added minimal IBM assembly syntax support for PowerPC.
153    
154      - Cygwin: manually changed the file cygwin.def.  Some exported symbols have
155        been altered in the runtime.  We need an automatic way to keep the file
156        in sync.

170    Description:
171    
172    Added low-level support for choosing C calling conventions by
173    twiddling the type of rawccall.  (See

200    
201    Gearing up towards 110.47...
202    
203    - various minor bugfixes to ml-nlffigen
204    - a beginning of a manual for nlffi
205    
206    - eliminated 'export name=value' in config/install.sh as this does
207      not work with certain versions of /bin/sh
208      (Thanks to David King at Motorola for catching this.)
209    
210    - several bugfixes provided or suggested by David Hansel at Reactive Systems:
211      - added a test for tm==NULL to gmtime.c and localtime.c
212      - applied patch for incorrect GetFileTime under win32
213      - toSeconds -> toMilliseconds in Win32/win32-process.sml

220    
221    - Fixed minor issue in ml-nlffigen: Now generate structure T_foo
222      for a typedef to an incomplete type, but leave out the "typ" member.
223      (This is just for consistency.)
224    - Started to produce what is supposed to become better (i.e., comprehensive)
225      documentation of what ml-nlffigen does and produces.

231    Description:
232    
233    Added C_UNION to c-calls/c-types.sml and updated the machinery
234    (ml-nlffigen, cproto.sml) that conveys C function interface
235    information to the code generator.
236    
237    However, the actual architecture-specific implementation of function
238    arguments and results that are C unions is still not implemented.

248        STWU(X), STFDU, STFSU
249

259    
260       Added the two instructions LWARX and STWCX to the PowerPC
261    instruction set.
262    
263       A (untested) rewrite of loop-structure.sml.  The old version
264    is completely broken.

269    Tag: blume-20040713-nlffi
270    Description:
271    
272    - use paramAlloc to report c-calls with too many arguments
273      (for PPC version where parameter area is pre-allocated)
274    - added ccall_maxargspace to machspec (to implement the above)
275    - made "make" commend in CM's "make" tool configurable
276    - added option (default: on) for passing the name of the SML/NJ's "bin"
277      directory to "make"; the call looks like this:
278    
279         make <options> SMLNJ_BINDIR=<dir> <target>
280    
281      This can be used by the Makefile to, e.g., pick the "right" version
282      of ml-nlffigen.
283    - minor code tweaks

289    Description:
290    
291    NLFFI under Mac OS X now working (sort of).  This is largely untested,
292    though.
293    
294    Note:  1. You have to make a new, clean build of the runtime system.
295           2. There are new BOOTFILES, you have to use them!
296              (Doing the bootstrap process yourself would be *very* painful!
297               If you absolutely have to do it, build the system under
298               a different architecture and then cross-compile.)
299    
300    Version bumped to 110.46.1 to account for runtime data format changes.

305    Tag: blume-20040618-unix
306    Description:
307    
308    Changed the implementation of structure Unix so that the same stream
309    is returned every time one of the {text,bin}{In,Out}streamOf functions
310    is invoked on the same proc.  This is not what the spec currently
311    says -- although IMO it arguably should.  (See discussion below.)

324    Tag: blume-20040617-timer-unix
325    Description:
326    
327    Changed the interface of structures Timer and Unix to match the most
328    recent Basis spec.
329    
330    In the case of Unix there still seems to be an open/weird issue:
331    
332       The {text,bin}{In,Out}streamOf functions are supposed to create
333       fresh streams whenever they are called -- as opposed to have them
334       return the same stream every time.  This design is supposed to
335       prevent space leaks caused by proc values hanging on to streams.
336    
337       The reap function, on the other hand, is supposed to close the
338       streams.  This cannot be done without having a handle on the
339       stream in proc after all...
340    
341    I took the liberty to implement the following stopgap solution:
342    
343      The proc value hangs on to the most recently created stream(s).
344      Reap closes those.  If either or both of the two streams hadn't
345      been created at all yet, then reap will close the corresponding
346      file descriptors directly.
347    
348    PS: I don't understand the original space leak argument anymore.  If
349    a proc hangs on to the imperative stream, then I/O operations on those
350    will advance the state of the cached stream and avoid the space leak.

363    Tag: blume-20040525-group-owner
364    Description:
365    
366    CM now ignores (but still accepts) the "owner" information in group
367    descriptions.  The owner of a group is its next enclosing
368    library. Each group must have a unique owner.  (There is a virtual
369    "toplevel" library that owns groups which are not nested within a real
370    library.)  Previously, each group had to explicitly declare its owner,
371    and CM would check that such a declaration is correct.  The new scheme
372    is to have CM check that for each group there is precisely one owning
373    library.
374    
375    The advantage of the new scheme is that the programmer no longer needs
376    to maintain the somewhat annoying owner information.  The downside is
377    that CM cannot enforce the ownership rule across multiple runs of
378    CM.make.  Fortunately, enclosing the same group in two different
379    libraries A and B which are not part of the same program does not
380    cause real problems.

388    Made the win32 version work again.  (Strangely, a misplaced comma had

390    compiled correctly.)
391    
392    Also, included a minor addition to ml-build.bat analogous to what was
393    done in blume-20040519-ml-build.

399    Description:
400    
401    Arranged for ml-build to clean up after itself a little bit better.
402    The script generates a temporary SML source file and compiles it using
403    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
404    gets rid of those at the end, so they don't accumulate under .cm.
405    
406    This required a minor change to install.sh because the name of the
407    metadata directory (default: .cm) is actually configurable at
408    installation time.

423    Description:
424    
425    Added previously missing support for many socket-related functions
426    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
427    for the voluminous patch!
428    
429    (I have not tested this patch under win32 yet.)
430    
431    Here is David's e-mail:
432    
433    Hi,
434    
435    Attached to this email you find a diff against sml/nj 110.45
436    that will enable socket support under Windows.
437    
438    To apply the patch (using unix or cygwin)
439    1) gunzip runtime.diff.gz
440    2) "cd" into "src/runtime" in the source tree of a fresh
441       110.45 installation.
442    3) patch -p 1 < [your/path/to]runtime.diff
443    
444    The code compiles fine but has NOT yet been extensively tested.
445    I only ran a few tests for basic socket client functionality
446    (which worked fine).  Especially the functions that use ioctl
447    are not tested at all and might not work (see below).
448    
449    I implemented this since we want to move to a newer version of sml/nj
450    but need socket support in order to use it.  This is the first time I
451    even had a look at the sml/nj source,  so please review my changes
452    before making this part of the distribution!  Here are a few issues
453    that I think might be better for someone to solve who is more
454    familiar with the sml/nj source (and socket programming):
455    
456    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
457      exception since I could not figure out what the windows equivalent
458      of these functions is
459    
460    - In sockets-osdep.h there are a some #include statements that are
461      only used in a few files that include sockets-osdep.h
462    
463    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
464      does not process its return value since I don't know how to
465      report an error upwards.
466    
467    - It would probably be good to have a call to WSACleanup() when
468      the library is unloaded (if there is such a possibility).
469      Otherwise I think Windows will take care of this automatically
470      when the process finishes.
471    
472    - I used ioctlsocket() as a replacement for ioctl() but I have
473      no idea if that is actually the proper replacement on Windows.
474    
475    - All these issues are marked in the code by "FIXME" comments.
476    
477    We use sml/nj extensively in our products and are quite happy
478    with it.  I hope this contribution will help you.
479    
480    Keep up the good work!

515    Description:
516    
517    The installer now honors the "src-smlnj" target again, although its meaning
518    has changed from "all sources required for the compiler" to "all sources
519    the installer knows about".  In other words, if you enable "src-smlnj"
520    in the "targets" file, then the installer will pull in sources for
521    everything.  (Notice that this refers to source code only.  Compiled
522    code is still only installed for modules that were requested explicitly
523    or which are required for other modules that were requested explicitly.)

557    Description:
558    
559    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
560    of SML/NJ.  The problem is that
561    
562       lib = dlopen(NULL, ...)
563       f   = dlsym(lib, "malloc");
564    
565    does not work on Windows unless we explicitly export symbols
566    such as 'malloc' during linking.  We fixed this by explicitly
567    exporting the required symbols with the magic gcc incantation:
568    
569        -Wl,--export-all cygwin.def
570    
571    where cygwin.def is a file containing all the symbols that
572    we wish to export.
573    
574    I suspect this is a Windows problem and we'll have to
575    do the same (somehow with windows compilers) when
576    we build the native win32 version with the system
577    calls LoadLibrary/GetProcAddress.

648    (The mechanism was broken and could not be fixed easily.  Moreover,
649    there does not seem to be any reason not to move all libraries into
650    lib during installation.  I originally implemented this directive as a
651    backward-compatibility feature when I first introduced the new CM.
652    Now that things have been stable for a long time and going back to the
653    old CM is not an option, there is no reason to keep it around.)

702    Tag: blume-20030926-ppautoload
703    Description:
704    
705    I modified the read-eval-print loop so that the autoloader gets
706    invoked whenever the prettyprinter tries to look up a symbol that
707    is not currently defined in the toplevel environment but which
708    appears in CM's autoload registry.  As a result, we see far fewer of
709    those ?.Foo.Bar.xxx names in the prettyprinter's output.
710    
711    In addition to this I tried to clean up some pieces of the Basis
712    implementation (e.g., Socket, Word8Array) in order to prevent other
713    instances of these ?.Foo.Bar.xxx names from being printed.
714    
715    The mechanism that picks names for types still needs some work, though.
716    (Right now it seems that if there is a type A.t which is defined to
717    be B.u, but B is unavailable at toplevel, then A.t gets printed as
718    "?.B.u" although the perhaps more sensible solution would be to use
719    "A.t" in this case.  In other words, the prettyprinter should follow
720    a chain of DEFtycs not farther than there are corresponding toplevel
721    names in the current environment.)

727    Description:
728    
729    Another installer tweak:  All the ML code for the installer is now
730    compiled during CMB.make and put into a little library called
731    $smlnj/installer.cm.  The installation then simply invokes
732    
733       sml -m $smlnj/installer.cm
734    
735    and everything happens automagically.
736    
737    Win32:  ML code senses value of environment variable SMLNJ_HOME.
738    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
739            and BINDIR.
740    
741    The new scheme guarantees that the ML code responsible for the installation
742    is in sync with the APIs of the main system.  Also, the installer is
743    somewhat faster because the installer script is precompiled.

754    implementations of non-blocking operations from CML's Socket
755    structure.

760    Tag: blume-20030924-sockets
761    Description:
762    
763    1. Fixed SOCKET API and implementation to match Basis spec.
764       This required changing the internal representation of sockets to one
765       that remembers (for each socket file descriptor) whether it is currently
766       blocking or non-blocking.  This state is maintained lazily (i.e., a system
767       call is made only if the state actually needs to change).
768    
769    2. OS-specific details of sockets were moved into separate files, thus
770       making it possible to unify the bulk of the socket implementations
771       between Unix and Win32.
772    
773    3. CML's socket API changed accordingly.
774       (Note that we need to remove non-blocking functions from this API
775       since they are redundant in the case of CML!)
776    
777    4. CML's socket implementation now makes use of non-blocking functions
778       provided by Basis, thus removing all OS-dependent code from this part
779       of CML.
780    
781    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

894    Description:
895    
896    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
897    Modified config/install.bat to take advantage of it.  Also modified
898    config/install.sh (and called it config/new-install.sh) to take advantage
899    of it on Unix systems.  (The SML code is (supposed to be) platform-
900    independent.)
901    
902    The installer can now install everything under Win32
903    as well as under *nix as long as it compiles.
904    
905    Other changes:
906    
907      - made CML compile again under Win32
908      - made eXene compile under Win32 (by providing a fake structure UnixSock
909        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
910      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
911        same as type int;  under Win32 it isn't
912      - fixed some slice-related problems in the win32-specific parts of CML
913      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
914        (under Win32, the volume name is case-insensitive, and the
915        OS.Path code compares volume names for equality)

932    Description:
933    
934      1. Changed interface to vectors and arrays in Basis to match
935         (draft) Basis spec.
936      2. Added signatures and implementations of slices according to
937         Basis spec.
938      3. Edited source code throughout the system to make it compile again
939         under 1. and 2.  (In some cases code had to be added to have it
940         match the new signatures.)
941      4. MLRISC should be backward-compatible: the copies of the originals
942         of files that needed to change under 3. were retained, the .cm files
943         check the compiler version number and use old versions when
944         appropriate.
945      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
946         dirstream -> string option (in accordance with Basis spec).
947      6. When generating code that counts lines, ml-lex used function
948         CharVector.foldli, taking advantage of its old interface.
949         This has been replaced with the corresponding code from
950         CharVectorSlice.  (html-lex must be re-lexed!)
951      7. BitArray in smlnj-lib/Util has been extended/modified to match the
952         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
953      8. Removed temporary additions (fromInternal, toInternal) from the
954         (now obsolete) IntInf in smlnj-lib/Util.
955      9. Cleaned up structure Byte.
956     10. Added localOffset, scan, and fromString to Date (according to spec).
957         Cleaned/corrected implementation of Date.
958         (Still need to check for correctness; implement better canonicalizeDate.)
959     11. Added "scan" to signature IEEE_REAL.
960     12. Some improvements to IntInf [in particular: efficiency-hack for
961         mod and rem when second operand is 2 (for parity checks).]
962     13. Changed representation of type Time.time, using a single IntInf.int
963         value counting microseconds.  This considerably simplified the
964         implementation of structure Time.  We now support negative time
965         values; scan and fromString handle signs.
966     14. Functor PrimIO now takes two additional arguments (VectorSlice and
967         ArraySlice).

972    Tag: blume-20030828-intinf
973    Description:
974    
975    This is a major update which comes with a version number bump
976    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
977    and an implementation of IntInf in the Basis.
978    
979    There are a fairly large number of related changes and updates throughout
980    the system:
981    
982    Basis:
983            - Implemented IntInf.
984            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
985            - Added some missing Real64 operations, most notably Real.toLargeInt.
986            - Added FixedInt as a synonym for Int32.
987    
988    compiler:
989            * Added support for a built-in intinf type.
990              - literals
991              - pattern matching
992              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
993              - overloading on literals and operations
994    
995            This required adding a primitive type intinf, some additional
996            primops, and implementations for several non-trivial intinf
997            operations in Core.  (The intinf type is completely abstract
998            to the compiler; all operations get delegated back to the Core.)
999    
1000            * Intinf equality is handled by polyequal.  However, the compiler
1001            does not print its usual warning in this case (since polyequal
1002            is the right thing to do there).
1003    
1004            * Improved the organization of structure InlineT.
1005    
1006            * A word about conversion primops:
1007            If conversions involving intinf do not cancel out during
1008            CPS contract, then the compiler must insert calls to Core functions.
1009            Since all core access must be resolved already during the FLINT
1010            translate phase, it would be too late a the time of CPS contract
1011            to add new Core calls.  For this reason, conversion primops
1012            for intinf carry two arguments:  1. the numeric argument that
1013            they are supposed to convert, and 2. the Core function that
1014            can help with this conversion if necessary.  If CPS contract
1015            eliminates a primop, then the associated Core function becomes
1016            dead and goes away.  Intinf conversion primops that do not get
1017            eliminated by CPS contract get rewritten into calls of their
1018            core functions by a separate, new phase.
1019    
1020    interactive system:
1021            - Control.Print.intinfDepth controls max length of intinf constants
1022            being printed. (Analogous to Control.Print.stringDepth.)
1023            - Cleanup in printutil and pputil: got rid of unused stuff and
1024            duplicates; replaced some of the code with code that makes better
1025            use of library functionality.
1026    
1027    CM:
1028            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
1029            are no longer silent.
1030    
1031    CKIT:
1032            Fixed mismatched uses of Int32 and LargeInt.  I always decided
1033            in favor of LargeInt -- which is now the same as IntInf.
1034            CKIT-knowledgable people should check whether this is what's
1035            intended and otherwise change things back to using Int32 or
1036            FixedInt.
1037    
1038    Throughout the code:
1039            Started using IntInf.int literals and built-in operations
1040            (e.g., comparison with 0) where this seems appropriate.

1060    Description:
1061    
1062    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
1063    
1064        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
1065    
1066    This patch restores SML/NJ's ability to run under win32.  There are a
1067    number of changes, including fixes for several bugs that had gone
1068    unnoticed until now:
1069    
1070      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
1071        trying to run the win32 version from within cygwin.)
1072    
1073      - There are a number of simple .bat scripts that substitute for their
1074        corresponding Unix shell-scripts.  (See below.)
1075    
1076      - The internals of ml-build have been modified slightly.  The main
1077        difference is that instead of calling ".link-sml" (or link-sml.bat)
1078        using OS.Process.system, the ML process delegates this task back
1079        to the script.  Otherwise problems arise in mixed environments such
1080        as Cygwin where scripts look and work like Unix scripts, but
1081        where OS.Process.system cannot run them.
1082    
1083      - In CM, the srcpath pickler used native pathname syntax -- which
1084        is incorrect in the case of cross-compilation.  The new pickle format
1085        is independent of platform-specific naming conventions.
1086    
1087      - Path configuration files (such as lib/pathconfig) can now choose
1088        between native and standard syntax.  Placing a line of the form
1089    
1090            standard!
1091    
1092        into the file causes all subsequent paths to be interpreted using
1093        CM standard pathname syntax (= Unix conventions); a line
1094    
1095            native!
1096    
1097        switches back to native style.  This was needed so that
1098        path config files can be written portably, see src/system/pathconfig.
1099    
1100      - Runtime system:
1101    
1102          - win32-filesys.c:  get_file_time and set_file_time now
1103            access modification time, not creation time.
1104    
1105          - I/O code made aware of new array representation.
1106    
1107          - Bug fixes in X86.prim.masm.
1108    
1109       - src/system/makeml made aware of win32. (For use under cygwin
1110            and other Unix-environments for windows.)
1111    
1112       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
1113         which caused BinIO.inputAll to fail consistently.
1114    
1115    .bat scripts:
1116    
1117       Windows .bat scripts assume that SMLNJ_HOME is defined.
1118    
1119       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
1120         applications (sml, ml-yacc, ml-lex).
1121       - ml-build.bat: analogous to ml-build.
1122       - config\install.bat:  Analogous to config/install.sh.  This requires
1123         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
1124         (nmake etc. must be on the path, and vcvars32 must have been run.)
1125         Moreover, sources for ml-lex and ml-yacc need to exist under src,
1126         and the bootfile hierarchy must have been unpacked under
1127         sml.boot.x86-win32.
1128         The script is very primitive and does a poor job at error checking.
1129         It only installs the base system, ml-lex, and ml-yacc.  No other
1130         libraries are being installed (i.e., you get only those that
1131         are part of the compiler.)
1132       - link-sml.bat:  analogous to .link-sml, but not currently used
1133    
1134    Unrelated bug fixes:
1135    
1136      - ml-nlffigen now exports structures ST_* corresponding to incomplete
1137        types.
1138      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
1139        otherwise.)

1165    Two changes:

1167      1. Added a flag for controlling whether non-exhaustive bindings will
1168         be treated as errors (default is false).
1169      2. Cleaned up the *entire* source tree so that CMB.make goes through
1170         without a single non-exhaustive match- or bind warning.

1177    
1178    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
1179    
1180       This mainly affects the quality of error messages.  However, some
1181       of the code is now more straightforward than before. (Treatment of
1182       the above four constructs in translate.sml is much simpler than
1183       the "macro-expansion" that was going on before.  Plus, the mach-
1184       compiler no longer gets invoked just to be able to compile an
1185       if-expression.)
1186    
1187    2. The ErrorMsg.Error exception is now caught and absorbed by the
1188       interactive loop.

1195    
1196        Ported the runtime system to cygwin, which uses the unix
1197    x86-unix bin files.  Missing/buggy features:
1198    
1199       o getnetbyname, getnetbyaddr: these functions seem to be missing in
1200         the Cygwin library.
1201       o Ctrl-C handling may be flaky.
1202       o Windows system calls and Windows I/O are not supported.
1203    
1204       A new set of binfiles is located at:
1205    
1206         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
1207    
1208       This is only needed for bootstrapping the cygwin version of smlnj.
1209       Other x86 versions can use the existing binfiles.
