20    
21    Bug fix from Carl Hauser:
22    
23    single_source_shortest_paths in dijkstra.sml was observed to get wrong
24    answers (by comparing to single_source_shortest_paths in bellman-ford.sml).
25    
26    The problem is that following the expression A.update(dist,s,Num.zero)
27    it is necessary to update the priority queue using Q.decreaseWeight(Q,s).

33    Description:
34    
35    Fiddled with handling of command-line options:
36    
37      * sml now quits after processing the command line
38        if -H, -S, -h<n>, or -s<n> appears as the last
39        command-line argument
40      * a new option -q terminates the session when encountered on
41        the command line; subsequent arguments will be ignored
42      * bug fixes: short (erroneous) arguments are no longer ignored
43        completely

49    Description:
50    
51      - Added minimal IBM assembly syntax support for PowerPC.
52    
53      - Cygwin: manually changed the file cygwin.def.  Some exported symbols have
54        been altered in the runtime.  We need an automatic way to keep the file
55        in sync.

81    Backed out of change to win32-filesys.c.  The earlier patch to
82    get_file_time caused CM to produce files with the wrong time stamp.

90    Added NLFFI support for Win32, adapted from a patch provided by David
91    Hansel.  This is currently completely untested.  Also, the issue
92    concerning stdcall vs. ccall is still unresolved.

99    
100    Gearing up towards 110.47...
101    
102    - various minor bugfixes to ml-nlffigen
103    - a beginning of a manual for nlffi
104    
105    - eliminated 'export name=value' in config/install.sh as this does
106      not work with certain versions of /bin/sh
107      (Thanks to David King at Motorola for catching this.)
108    
109    - several bugfixes provided or suggested by David Hansel at Reactive Systems:
110      - added a test for tm==NULL to gmtime.c and localtime.c
111      - applied patch for incorrect GetFileTime under win32
112      - toSeconds -> toMilliseconds in Win32/win32-process.sml

118    Description:
119    
120    - Fixed minor issue in ml-nlffigen: Now generate structure T_foo
121      for a typedef to an incomplete type, but leave out the "typ" member.
122      (This is just for consistency.)
123    - Started to produce what is supposed to become better (i.e., comprehensive)
124      documentation of what ml-nlffigen does and produces.

130    Description:
131    
132    Added C_UNION to c-calls/c-types.sml and updated the machinery
133    (ml-nlffigen, cproto.sml) that conveys C function interface
134    information to the code generator.
135    
136    However, the actual architecture-specific implementation of function
137    arguments and results that are C unions is still not implemented.

147        STWU(X), STFDU, STFSU
148    
149        etc...
150    
151        Note: I haven't added their instruction encoding into the description.

158    
159       Added the two instructions LWARX and STWCX to the PowerPC
160    instruction set.
161    
162       A (untested) rewrite of loop-structure.sml.  The old version
163    is completely broken.

168    Tag: blume-20040713-nlffi
169    Description:
170    
171    - use paramAlloc to report c-calls with too many arguments
172      (for PPC version where parameter area is pre-allocated)
173    - added ccall_maxargspace to machspec (to implement the above)
174    - made "make" commend in CM's "make" tool configurable
175    - added option (default: on) for passing the name of the SML/NJ's "bin"
176      directory to "make"; the call looks like this:
177    
178         make <options> SMLNJ_BINDIR=<dir> <target>
179    
180      This can be used by the Makefile to, e.g., pick the "right" version
181      of ml-nlffigen.
182    - minor code tweaks

188    Description:
189    
190    NLFFI under Mac OS X now working (sort of).  This is largely untested,
191    though.
192    
193    Note:  1. You have to make a new, clean build of the runtime system.
194           2. There are new BOOTFILES, you have to use them!
195              (Doing the bootstrap process yourself would be *very* painful!
196               If you absolutely have to do it, build the system under
197               a different architecture and then cross-compile.)
198    
199    Version bumped to 110.46.1 to account for runtime data format changes.

204    Tag: blume-20040618-unix
205    Description:
206    
207    Changed the implementation of structure Unix so that the same stream
208    is returned every time one of the {text,bin}{In,Out}streamOf functions
209    is invoked on the same proc.  This is not what the spec currently
210    says -- although IMO it arguably should.  (See discussion below.)

223    Tag: blume-20040617-timer-unix
224    Description:
225    
226    Changed the interface of structures Timer and Unix to match the most
227    recent Basis spec.
228    
229    In the case of Unix there still seems to be an open/weird issue:
230    
231       The {text,bin}{In,Out}streamOf functions are supposed to create
232       fresh streams whenever they are called -- as opposed to have them
233       return the same stream every time.  This design is supposed to
234       prevent space leaks caused by proc values hanging on to streams.
235    
236       The reap function, on the other hand, is supposed to close the
237       streams.  This cannot be done without having a handle on the
238       stream in proc after all...
239    
240    I took the liberty to implement the following stopgap solution:
241    
242      The proc value hangs on to the most recently created stream(s).
243      Reap closes those.  If either or both of the two streams hadn't
244      been created at all yet, then reap will close the corresponding
245      file descriptors directly.
246    
247    PS: I don't understand the original space leak argument anymore.  If
248    a proc hangs on to the imperative stream, then I/O operations on those
249    will advance the state of the cached stream and avoid the space leak.

262    Tag: blume-20040525-group-owner
263    Description:
264    
265    CM now ignores (but still accepts) the "owner" information in group
266    descriptions.  The owner of a group is its next enclosing
267    library. Each group must have a unique owner.  (There is a virtual
268    "toplevel" library that owns groups which are not nested within a real
269    library.)  Previously, each group had to explicitly declare its owner,
270    and CM would check that such a declaration is correct.  The new scheme
271    is to have CM check that for each group there is precisely one owning
272    library.
273    
274    The advantage of the new scheme is that the programmer no longer needs
275    to maintain the somewhat annoying owner information.  The downside is
276    that CM cannot enforce the ownership rule across multiple runs of
277    CM.make.  Fortunately, enclosing the same group in two different
278    libraries A and B which are not part of the same program does not
279    cause real problems.

285    Description:
286    
287    Made the win32 version work again.  (Strangely, a misplaced comma had
288    slipped into win32-process.c which prevented the runtime from being
289    compiled correctly.)
290    
291    Also, included a minor addition to ml-build.bat analogous to what was
292    done in blume-20040519-ml-build.

297    Tag: blume-20040519-ml-build
298    Description:
299    
300    Arranged for ml-build to clean up after itself a little bit better.
301    The script generates a temporary SML source file and compiles it using
302    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
303    gets rid of those at the end, so they don't accumulate under .cm.
304    
305    This required a minor change to install.sh because the name of the
306    metadata directory (default: .cm) is actually configurable at
307    installation time.

321    Tag: blume-20040511-win32sock
322    Description:
323    
324    Added previously missing support for many socket-related functions
325    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
326    for the voluminous patch!
327    
328    (I have not tested this patch under win32 yet.)
329    
330    Here is David's e-mail:
331    
332    Hi,
333    
334    Attached to this email you find a diff against sml/nj 110.45
335    that will enable socket support under Windows.
336    
337    To apply the patch (using unix or cygwin)
338    1) gunzip runtime.diff.gz
339    2) "cd" into "src/runtime" in the source tree of a fresh
340       110.45 installation.
341    3) patch -p 1 < [your/path/to]runtime.diff
342    
343    The code compiles fine but has NOT yet been extensively tested.
344    I only ran a few tests for basic socket client functionality
345    (which worked fine).  Especially the functions that use ioctl
346    are not tested at all and might not work (see below).
347    
348    I implemented this since we want to move to a newer version of sml/nj
349    but need socket support in order to use it.  This is the first time I
350    even had a look at the sml/nj source,  so please review my changes
351    before making this part of the distribution!  Here are a few issues
352    that I think might be better for someone to solve who is more
353    familiar with the sml/nj source (and socket programming):
354    
355    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
356      exception since I could not figure out what the windows equivalent
357      of these functions is
358    
359    - In sockets-osdep.h there are a some #include statements that are
360      only used in a few files that include sockets-osdep.h
361    
362    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
363      does not process its return value since I don't know how to
364      report an error upwards.
365    
366    - It would probably be good to have a call to WSACleanup() when
367      the library is unloaded (if there is such a possibility).
368      Otherwise I think Windows will take care of this automatically
369      when the process finishes.
370    
371    - I used ioctlsocket() as a replacement for ioctl() but I have
372      no idea if that is actually the proper replacement on Windows.
373    
374    - All these issues are marked in the code by "FIXME" comments.
375    
376    We use sml/nj extensively in our products and are quite happy
377    with it.  I hope this contribution will help you.
378    
379    Keep up the good work!
380

414    Description:

416    The installer now honors the "src-smlnj" target again, although its meaning
417    has changed from "all sources required for the compiler" to "all sources
418    the installer knows about".  In other words, if you enable "src-smlnj"
419    in the "targets" file, then the installer will pull in sources for
420    everything.  (Notice that this refers to source code only.  Compiled
421    code is still only installed for modules that were requested explicitly
422    or which are required for other modules that were requested explicitly.)

462       f   = dlsym(lib, "malloc");
463    
464    does not work on Windows unless we explicitly export symbols
465    such as 'malloc' during linking.  We fixed this by explicitly
466    exporting the required symbols with the magic gcc incantation:
467    
468        -Wl,--export-all cygwin.def
469    
470    where cygwin.def is a file containing all the symbols that
471    we wish to export.
472    
473    I suspect this is a Windows problem and we'll have to
474    do the same (somehow with windows compilers) when
475    we build the native win32 version with the system
476    calls LoadLibrary/GetProcAddress.

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

602    Description:
603    
604    I modified the read-eval-print loop so that the autoloader gets
605    invoked whenever the prettyprinter tries to look up a symbol that
606    is not currently defined in the toplevel environment but which
607    appears in CM's autoload registry.  As a result, we see far fewer of
608    those ?.Foo.Bar.xxx names in the prettyprinter's output.
609    
610    In addition to this I tried to clean up some pieces of the Basis
611    implementation (e.g., Socket, Word8Array) in order to prevent other
612    instances of these ?.Foo.Bar.xxx names from being printed.
613    
614    The mechanism that picks names for types still needs some work, though.
615    (Right now it seems that if there is a type A.t which is defined to
616    be B.u, but B is unavailable at toplevel, then A.t gets printed as
617    "?.B.u" although the perhaps more sensible solution would be to use
618    "A.t" in this case.  In other words, the prettyprinter should follow
619    a chain of DEFtycs not farther than there are corresponding toplevel
620    names in the current environment.)

626    Description:
627    
628    Another installer tweak:  All the ML code for the installer is now
629    compiled during CMB.make and put into a little library called
630    $smlnj/installer.cm.  The installation then simply invokes
631    
632       sml -m $smlnj/installer.cm
633    
634    and everything happens automagically.
635    
636    Win32:  ML code senses value of environment variable SMLNJ_HOME.
637    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
638            and BINDIR.
639    
640    The new scheme guarantees that the ML code responsible for the installation
641    is in sync with the APIs of the main system.  Also, the installer is
642    somewhat faster because the installer script is precompiled.

653    implementations of non-blocking operations from CML's Socket
654    structure.

659    Tag: blume-20030924-sockets
660    Description:
661    
662    1. Fixed SOCKET API and implementation to match Basis spec.
663       This required changing the internal representation of sockets to one
664       that remembers (for each socket file descriptor) whether it is currently
665       blocking or non-blocking.  This state is maintained lazily (i.e., a system
666       call is made only if the state actually needs to change).
667    
668    2. OS-specific details of sockets were moved into separate files, thus
669       making it possible to unify the bulk of the socket implementations
670       between Unix and Win32.
671    
672    3. CML's socket API changed accordingly.
673       (Note that we need to remove non-blocking functions from this API
674       since they are redundant in the case of CML!)
675    
676    4. CML's socket implementation now makes use of non-blocking functions
677       provided by Basis, thus removing all OS-dependent code from this part
678       of CML.
679    
680    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

793    Description:
794    
795    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
796    Modified config/install.bat to take advantage of it.  Also modified
797    config/install.sh (and called it config/new-install.sh) to take advantage
798    of it on Unix systems.  (The SML code is (supposed to be) platform-
799    independent.)
800    
801    The installer can now install everything under Win32
802    as well as under *nix as long as it compiles.
803    
804    Other changes:
805    
806      - made CML compile again under Win32
807      - made eXene compile under Win32 (by providing a fake structure UnixSock
808        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
809      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
810        same as type int;  under Win32 it isn't
811      - fixed some slice-related problems in the win32-specific parts of CML
812      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
813        (under Win32, the volume name is case-insensitive, and the
814        OS.Path code compares volume names for equality)

831    Description:
832    
833      1. Changed interface to vectors and arrays in Basis to match
834         (draft) Basis spec.
835      2. Added signatures and implementations of slices according to
836         Basis spec.
837      3. Edited source code throughout the system to make it compile again
838         under 1. and 2.  (In some cases code had to be added to have it
839         match the new signatures.)
840      4. MLRISC should be backward-compatible: the copies of the originals
841         of files that needed to change under 3. were retained, the .cm files
842         check the compiler version number and use old versions when
843         appropriate.
844      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
845         dirstream -> string option (in accordance with Basis spec).
846      6. When generating code that counts lines, ml-lex used function
847         CharVector.foldli, taking advantage of its old interface.
848         This has been replaced with the corresponding code from
849         CharVectorSlice.  (html-lex must be re-lexed!)
850      7. BitArray in smlnj-lib/Util has been extended/modified to match the
851         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
852      8. Removed temporary additions (fromInternal, toInternal) from the
853         (now obsolete) IntInf in smlnj-lib/Util.
854      9. Cleaned up structure Byte.
855     10. Added localOffset, scan, and fromString to Date (according to spec).
856         Cleaned/corrected implementation of Date.
857         (Still need to check for correctness; implement better canonicalizeDate.)
858     11. Added "scan" to signature IEEE_REAL.
859     12. Some improvements to IntInf [in particular: efficiency-hack for
860         mod and rem when second operand is 2 (for parity checks).]
861     13. Changed representation of type Time.time, using a single IntInf.int
862         value counting microseconds.  This considerably simplified the
863         implementation of structure Time.  We now support negative time
864         values; scan and fromString handle signs.
865     14. Functor PrimIO now takes two additional arguments (VectorSlice and
866         ArraySlice).

872    Description:
873    
874    This is a major update which comes with a version number bump
875    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
876    and an implementation of IntInf in the Basis.
877    
878    There are a fairly large number of related changes and updates throughout
879    the system:
880    
881    Basis:
882            - Implemented IntInf.
883            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
884            - Added some missing Real64 operations, most notably Real.toLargeInt.
885            - Added FixedInt as a synonym for Int32.
886    
887    compiler:
888            * Added support for a built-in intinf type.
889              - literals
890              - pattern matching
891              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
892              - overloading on literals and operations
893    
894            This required adding a primitive type intinf, some additional
895            primops, and implementations for several non-trivial intinf
896            operations in Core.  (The intinf type is completely abstract
897            to the compiler; all operations get delegated back to the Core.)
898    
899            * Intinf equality is handled by polyequal.  However, the compiler
900            does not print its usual warning in this case (since polyequal
901            is the right thing to do there).
902    
903            * Improved the organization of structure InlineT.
904    
905            * A word about conversion primops:
906            If conversions involving intinf do not cancel out during
907            CPS contract, then the compiler must insert calls to Core functions.
908            Since all core access must be resolved already during the FLINT
909            translate phase, it would be too late a the time of CPS contract
910            to add new Core calls.  For this reason, conversion primops
911            for intinf carry two arguments:  1. the numeric argument that
912            they are supposed to convert, and 2. the Core function that
913            can help with this conversion if necessary.  If CPS contract
914            eliminates a primop, then the associated Core function becomes
915            dead and goes away.  Intinf conversion primops that do not get
916            eliminated by CPS contract get rewritten into calls of their
917            core functions by a separate, new phase.
918    
919    interactive system:
920            - Control.Print.intinfDepth controls max length of intinf constants
921            being printed. (Analogous to Control.Print.stringDepth.)
922            - Cleanup in printutil and pputil: got rid of unused stuff and
923            duplicates; replaced some of the code with code that makes better
924            use of library functionality.
925    
926    CM:
927            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
928            are no longer silent.
929    
930    CKIT:
931            Fixed mismatched uses of Int32 and LargeInt.  I always decided
932            in favor of LargeInt -- which is now the same as IntInf.
933            CKIT-knowledgable people should check whether this is what's
934            intended and otherwise change things back to using Int32 or
935            FixedInt.
936    
937    Throughout the code:
938            Started using IntInf.int literals and built-in operations
939            (e.g., comparison with 0) where this seems appropriate.

959    Description:
960    
961    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
962    
963        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
964    
965    This patch restores SML/NJ's ability to run under win32.  There are a
966    number of changes, including fixes for several bugs that had gone
967    unnoticed until now:
968    
969      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
970        trying to run the win32 version from within cygwin.)
971    
972      - There are a number of simple .bat scripts that substitute for their
973        corresponding Unix shell-scripts.  (See below.)
974    
975      - The internals of ml-build have been modified slightly.  The main
976        difference is that instead of calling ".link-sml" (or link-sml.bat)
977        using OS.Process.system, the ML process delegates this task back
978        to the script.  Otherwise problems arise in mixed environments such
979        as Cygwin where scripts look and work like Unix scripts, but
980        where OS.Process.system cannot run them.
981    
982      - In CM, the srcpath pickler used native pathname syntax -- which
983        is incorrect in the case of cross-compilation.  The new pickle format
984        is independent of platform-specific naming conventions.
985    
986      - Path configuration files (such as lib/pathconfig) can now choose
987        between native and standard syntax.  Placing a line of the form
988    
989            standard!
990    
991        into the file causes all subsequent paths to be interpreted using
992        CM standard pathname syntax (= Unix conventions); a line
993    
994            native!
995    
996        switches back to native style.  This was needed so that
997        path config files can be written portably, see src/system/pathconfig.
998    
999      - Runtime system:
1000    
1001          - win32-filesys.c:  get_file_time and set_file_time now
1002            access modification time, not creation time.
1003    
1004          - I/O code made aware of new array representation.
1005    
1006          - Bug fixes in X86.prim.masm.
1007    
1008       - src/system/makeml made aware of win32. (For use under cygwin
1009            and other Unix-environments for windows.)
1010    
1011       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
1012         which caused BinIO.inputAll to fail consistently.
1013    
1014    .bat scripts:
1015    
1016       Windows .bat scripts assume that SMLNJ_HOME is defined.
1017    
1018       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
1019         applications (sml, ml-yacc, ml-lex).
1020       - ml-build.bat: analogous to ml-build.
1021       - config\install.bat:  Analogous to config/install.sh.  This requires
1022         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
1023         (nmake etc. must be on the path, and vcvars32 must have been run.)
1024         Moreover, sources for ml-lex and ml-yacc need to exist under src,
1025         and the bootfile hierarchy must have been unpacked under
1026         sml.boot.x86-win32.
1027         The script is very primitive and does a poor job at error checking.
1028         It only installs the base system, ml-lex, and ml-yacc.  No other
1029         libraries are being installed (i.e., you get only those that
1030         are part of the compiler.)
1031       - link-sml.bat:  analogous to .link-sml, but not currently used
1032    
1033    Unrelated bug fixes:
1034    
1035      - ml-nlffigen now exports structures ST_* corresponding to incomplete
1036        types.
1037      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
1038        otherwise.)

1067         be treated as errors (default is false).
1068      2. Cleaned up the *entire* source tree so that CMB.make goes through
1069         without a single non-exhaustive match- or bind warning.

1076    
1077    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
1078    
1079       This mainly affects the quality of error messages.  However, some
1080       of the code is now more straightforward than before. (Treatment of
1081       the above four constructs in translate.sml is much simpler than
1082       the "macro-expansion" that was going on before.  Plus, the mach-
1083       compiler no longer gets invoked just to be able to compile an
1084       if-expression.)
1085    
1086    2. The ErrorMsg.Error exception is now caught and absorbed by the
1087       interactive loop.

1093    Description:
1094    
1095        Ported the runtime system to cygwin, which uses the unix
1096    x86-unix bin files.  Missing/buggy features:
1097    
1098       o getnetbyname, getnetbyaddr: these functions seem to be missing in
1099         the Cygwin library.
1100       o Ctrl-C handling may be flaky.
1101       o Windows system calls and Windows I/O are not supported.
1102    
1103       A new set of binfiles is located at:
1104    
1105         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
1106    
1107       This is only needed for bootstrapping the cygwin version of smlnj.
1108       Other x86 versions can use the existing binfiles.

1138    110.37 and 110.38.)
1139    There was another set of potential problems related to the handling of
1140    MLRISC annotations (but those did not yet cause real problems, apparently).

1167    
1168    In good old tradition, there has been a slight hiccup so that we have
1169    to patch 110.42 after the fact.   The old release tag has been replaced
1170    (see below).
1171    
1172    The change solves a problem with two competing approaches the
1173    configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
1174    each other's way.
1175    
1176    This change only affects the runtime system code and the installer script.

1341       only libraries that can be preloaded via config/preloads are those
1342       that come bundled with the bootfiles.)

1359    o Made the mdl tool stuff compile and run again.
1360    o I've disabled all the stuff that depends on RTL specifications; they
1361      are all badly broken anyway.

1367    Description:
1368    
1369    0. John Reppy made several modifications to the SML/NJ library.
1370       In particular, there is a shiny new controls-lib.cm.
1371    
1372    1. Pushed new controls interface through compiler so that everything
1373       compiles again.
1374    
1375    2. Added FormatComb and FORMAT_COMB to the CML version of the
1376       SML/NJ library (so that CML compiles again).
1377    
1378    3. Modified init scripts because XXX_DEFAULT environment variables
1379       are no longer with us.  (Boot-time initialization is now done
1380       using the same environment variables that are also used for
1381       startup-time initialization of controls.)

1387    Description:
1388    
1389            All pseudo-ops emitted before the first segment declaration
1390    such as TEXT, DATA, and BSS directives are assumed to be global
1391    declarations and are emitted first in the assembly file. This is
1392    useful in a number of situations where one has pseudo-ops that are not
1393    specific to any segment, and also works around the constraint that one
1394    cannot have client pseudo-ops in the TEXT segment.
1395    
1396            Because no segment is associated with these declarations it is
1397    an error to allocate any space or objects before the first segment
1398    directive and an exception will be raised. However, we cannot make
1399    this check for client pseudo-ops.
1400    
1401            These top level declarations are a field in the CFG graph_info.
1402    In theory you can continue to add to this field after the CFG has been
1403    built -- provided you know what you are doing;-)

1410    
1411    A few minor bugfixes:
1412    
1413      - Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
1414        (Bogus printouts for redefined bindings still occur.  Compiler
1415        bug should no longer occur now.  We need to redo the prettyprinter
1416        from scratch.)
1417    
1418      - CM pathname printer now also adds escape sequences for ( and )
1419    
1420      - commend and docu fixes for ml-nlffi

1426    Description:
1427    
1428    Applied the following bugfix provided by Emden Gansner:
1429    
1430        Output is corrupted when outputSubstr is used rather than output.
1431    
1432        The problem occurs when a substring
1433    
1434            ss = (s, dataStart, dataLen)
1435    
1436        where dataStart > 0, fills a stream buffer with avail bytes left.
1437        avail bytes of s, starting at index dataStart, are copied into the
1438        buffer, the buffer is flushed, and then the remaining dataLen-avail
1439        bytes of ss are copied into the beginning of the buffer. Instead of
1440        starting this copy at index dataStart+avail in s, the current code
1441        starts the copy at index avail.
1442    
1443        Fix:
1444        In text-io-fn.sml, change line 695 from
1445             val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
1446        to
1447             val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

1455    1. Grabbed newer assyntax.h from the XFree86 project.
1456    2. Fiddled with how to compile X86.prim.asm without warnings.
1457    3. (Very) Minor cleanup in CM.

1463    Description:
1464    
1465    Added full support for div/mod/rem/quot on the x86, using the machine
1466    instruction's two results (without clumsily recomputing the remainder)
1467    directly where appropriate.
1468    
1469    Some more extensive power-of-two support was added to the x86 instruction
1470    selector (avoiding expensive divs, mods, and muls where they can be
1471    replaced with cheaper shifts and masks).  However, this sort of thing
1472    ought to be done earlier, e.g., within the CPS optimizer so that
1473    all architectures benefit from it.
1474    
1475    The compiler compiles to a fixed point, but changes might be somewhat
1476    fragile nevertheless.  Please, report any strange things that you might
1477    see wrt. div/mod/quot/rem...
