27    Description:
28    
29    Put target "mlrisc" back into the default list.
30    (There is no harm in having it, and some users have expressed their
31    wish to have "mlrisc" included by default.)

55    Description:
56    
57       Added a patch to _arch-n-opsys to enable the Cygwin runtime.
58    The Cygwin runtime is turned on by setting the environment
59    variable SMLNJ_CYGWIN_RUNTIME to 1.

73    Description:
74    
75    Upon request by Johannes Joemann:
76    
77    - improved ML code of installer to fall back to coping when renaming
78      fails (i.e., when source and target are on different file systems);
79      the code compiles but has yet to be tested in anger
80    - removed mlrisc from list of default targets (config/targets)

128    Description:
129    
130    Bug fix from Carl Hauser:
131    
132    single_source_shortest_paths in dijkstra.sml was observed to get wrong
133    answers (by comparing to single_source_shortest_paths in bellman-ford.sml).
134    
135    The problem is that following the expression A.update(dist,s,Num.zero)
136    it is necessary to update the priority queue using Q.decreaseWeight(Q,s).

141    Tag: blume-20040806-cmdline
142    Description:
143    
144    Fiddled with handling of command-line options:
145    
146      * sml now quits after processing the command line
147        if -H, -S, -h<n>, or -s<n> appears as the last
148        command-line argument
149      * a new option -q terminates the session when encountered on
150        the command line; subsequent arguments will be ignored
151      * bug fixes: short (erroneous) arguments are no longer ignored
152        completely

158    Description:
159    
160      - Added minimal IBM assembly syntax support for PowerPC.
161    
162      - Cygwin: manually changed the file cygwin.def.  Some exported symbols have
163        been altered in the runtime.  We need an automatic way to keep the file
164        in sync.

208    
209    Gearing up towards 110.47...
210    
211    - various minor bugfixes to ml-nlffigen
212    - a beginning of a manual for nlffi
213    
214    - eliminated 'export name=value' in config/install.sh as this does
215      not work with certain versions of /bin/sh
216      (Thanks to David King at Motorola for catching this.)
217    
218    - several bugfixes provided or suggested by David Hansel at Reactive Systems:
219      - added a test for tm==NULL to gmtime.c and localtime.c
220      - applied patch for incorrect GetFileTime under win32
221      - toSeconds -> toMilliseconds in Win32/win32-process.sml

227    Description:
228    
229    - Fixed minor issue in ml-nlffigen: Now generate structure T_foo
230      for a typedef to an incomplete type, but leave out the "typ" member.
231      (This is just for consistency.)
232    - Started to produce what is supposed to become better (i.e., comprehensive)
233      documentation of what ml-nlffigen does and produces.

239    Description:
240    
241    Added C_UNION to c-calls/c-types.sml and updated the machinery
242    (ml-nlffigen, cproto.sml) that conveys C function interface
243    information to the code generator.
244    
245    However, the actual architecture-specific implementation of function
246    arguments and results that are C unions is still not implemented.

256        STWU(X), STFDU, STFSU
257

270    
271       A (untested) rewrite of loop-structure.sml.  The old version
272    is completely broken.

277    Tag: blume-20040713-nlffi
278    Description:
279    
280    - use paramAlloc to report c-calls with too many arguments
281      (for PPC version where parameter area is pre-allocated)
282    - added ccall_maxargspace to machspec (to implement the above)
283    - made "make" commend in CM's "make" tool configurable
284    - added option (default: on) for passing the name of the SML/NJ's "bin"
285      directory to "make"; the call looks like this:
286    
287         make <options> SMLNJ_BINDIR=<dir> <target>
288    
289      This can be used by the Makefile to, e.g., pick the "right" version
290      of ml-nlffigen.
291    - minor code tweaks

297    Description:
298    
299    NLFFI under Mac OS X now working (sort of).  This is largely untested,
300    though.
301    
302    Note:  1. You have to make a new, clean build of the runtime system.
303           2. There are new BOOTFILES, you have to use them!
304              (Doing the bootstrap process yourself would be *very* painful!
305               If you absolutely have to do it, build the system under
306               a different architecture and then cross-compile.)
307    
308    Version bumped to 110.46.1 to account for runtime data format changes.

314    Description:
315    
316    Changed the implementation of structure Unix so that the same stream
317    is returned every time one of the {text,bin}{In,Out}streamOf functions
318    is invoked on the same proc.  This is not what the spec currently
319    says -- although IMO it arguably should.  (See discussion below.)

332    Tag: blume-20040617-timer-unix
333    Description:
334    
335    Changed the interface of structures Timer and Unix to match the most
336    recent Basis spec.
337    
338    In the case of Unix there still seems to be an open/weird issue:
339    
340       The {text,bin}{In,Out}streamOf functions are supposed to create
341       fresh streams whenever they are called -- as opposed to have them
342       return the same stream every time.  This design is supposed to
343       prevent space leaks caused by proc values hanging on to streams.
344    
345       The reap function, on the other hand, is supposed to close the
346       streams.  This cannot be done without having a handle on the
347       stream in proc after all...
348    
349    I took the liberty to implement the following stopgap solution:
350    
351      The proc value hangs on to the most recently created stream(s).
352      Reap closes those.  If either or both of the two streams hadn't
353      been created at all yet, then reap will close the corresponding
354      file descriptors directly.
355    
356    PS: I don't understand the original space leak argument anymore.  If
357    a proc hangs on to the imperative stream, then I/O operations on those
358    will advance the state of the cached stream and avoid the space leak.

371    Tag: blume-20040525-group-owner
372    Description:
373    
374    CM now ignores (but still accepts) the "owner" information in group
375    descriptions.  The owner of a group is its next enclosing
376    library. Each group must have a unique owner.  (There is a virtual
377    "toplevel" library that owns groups which are not nested within a real
378    library.)  Previously, each group had to explicitly declare its owner,
379    and CM would check that such a declaration is correct.  The new scheme
380    is to have CM check that for each group there is precisely one owning
381    library.
382    
383    The advantage of the new scheme is that the programmer no longer needs
384    to maintain the somewhat annoying owner information.  The downside is
385    that CM cannot enforce the ownership rule across multiple runs of
386    CM.make.  Fortunately, enclosing the same group in two different
387    libraries A and B which are not part of the same program does not
388    cause real problems.

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

399    
400    Also, included a minor addition to ml-build.bat analogous to what was
401    done in blume-20040519-ml-build.

407    Description:
408    
409    Arranged for ml-build to clean up after itself a little bit better.
410    The script generates a temporary SML source file and compiles it using
411    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
412    gets rid of those at the end, so they don't accumulate under .cm.
413    
414    This required a minor change to install.sh because the name of the
415    metadata directory (default: .cm) is actually configurable at
416    installation time.

431    Description:
432    
433    Added previously missing support for many socket-related functions
434    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
435    for the voluminous patch!
436    
437    (I have not tested this patch under win32 yet.)
438    
439    Here is David's e-mail:
440    
441    Hi,
442    
443    Attached to this email you find a diff against sml/nj 110.45
444    that will enable socket support under Windows.
445    
446    To apply the patch (using unix or cygwin)
447    1) gunzip runtime.diff.gz
448    2) "cd" into "src/runtime" in the source tree of a fresh
449       110.45 installation.
450    3) patch -p 1 < [your/path/to]runtime.diff
451    
452    The code compiles fine but has NOT yet been extensively tested.
453    I only ran a few tests for basic socket client functionality
454    (which worked fine).  Especially the functions that use ioctl
455    are not tested at all and might not work (see below).
456    
457    I implemented this since we want to move to a newer version of sml/nj
458    but need socket support in order to use it.  This is the first time I
459    even had a look at the sml/nj source,  so please review my changes
460    before making this part of the distribution!  Here are a few issues
461    that I think might be better for someone to solve who is more
462    familiar with the sml/nj source (and socket programming):
463    
464    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
465      exception since I could not figure out what the windows equivalent
466      of these functions is
467    
468    - In sockets-osdep.h there are a some #include statements that are
469      only used in a few files that include sockets-osdep.h
470    
471    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
472      does not process its return value since I don't know how to
473      report an error upwards.
474    
475    - It would probably be good to have a call to WSACleanup() when
476      the library is unloaded (if there is such a possibility).
477      Otherwise I think Windows will take care of this automatically
478      when the process finishes.
479    
480    - I used ioctlsocket() as a replacement for ioctl() but I have
481      no idea if that is actually the proper replacement on Windows.
482    
483    - All these issues are marked in the code by "FIXME" comments.
484    
485    We use sml/nj extensively in our products and are quite happy
486    with it.  I hope this contribution will help you.
487    
488    Keep up the good work!

523    Description:
524    
525    The installer now honors the "src-smlnj" target again, although its meaning
526    has changed from "all sources required for the compiler" to "all sources
527    the installer knows about".  In other words, if you enable "src-smlnj"
528    in the "targets" file, then the installer will pull in sources for
529    everything.  (Notice that this refers to source code only.  Compiled
530    code is still only installed for modules that were requested explicitly
531    or which are required for other modules that were requested explicitly.)

565    Description:
566    
567    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
568    of SML/NJ.  The problem is that
569    
570       lib = dlopen(NULL, ...)
571       f   = dlsym(lib, "malloc");
572    
573    does not work on Windows unless we explicitly export symbols
574    such as 'malloc' during linking.  We fixed this by explicitly
575    exporting the required symbols with the magic gcc incantation:
576    
577        -Wl,--export-all cygwin.def
578    
579    where cygwin.def is a file containing all the symbols that
580    we wish to export.
581    
582    I suspect this is a Windows problem and we'll have to
583    do the same (somehow with windows compilers) when
584    we build the native win32 version with the system
585    calls LoadLibrary/GetProcAddress.

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

710    Tag: blume-20030926-ppautoload
711    Description:
712    
713    I modified the read-eval-print loop so that the autoloader gets
714    invoked whenever the prettyprinter tries to look up a symbol that
715    is not currently defined in the toplevel environment but which
716    appears in CM's autoload registry.  As a result, we see far fewer of
717    those ?.Foo.Bar.xxx names in the prettyprinter's output.
718    
719    In addition to this I tried to clean up some pieces of the Basis
720    implementation (e.g., Socket, Word8Array) in order to prevent other
721    instances of these ?.Foo.Bar.xxx names from being printed.
722    
723    The mechanism that picks names for types still needs some work, though.
724    (Right now it seems that if there is a type A.t which is defined to
725    be B.u, but B is unavailable at toplevel, then A.t gets printed as
726    "?.B.u" although the perhaps more sensible solution would be to use
727    "A.t" in this case.  In other words, the prettyprinter should follow
728    a chain of DEFtycs not farther than there are corresponding toplevel
729    names in the current environment.)

735    Description:
736    
737    Another installer tweak:  All the ML code for the installer is now
738    compiled during CMB.make and put into a little library called
739    $smlnj/installer.cm.  The installation then simply invokes
740    
741       sml -m $smlnj/installer.cm
742    
743    and everything happens automagically.
744    
745    Win32:  ML code senses value of environment variable SMLNJ_HOME.
746    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
747            and BINDIR.
748    
749    The new scheme guarantees that the ML code responsible for the installation
750    is in sync with the APIs of the main system.  Also, the installer is
751    somewhat faster because the installer script is precompiled.

762    implementations of non-blocking operations from CML's Socket
763    structure.

768    Tag: blume-20030924-sockets
769    Description:
770    
771    1. Fixed SOCKET API and implementation to match Basis spec.
772       This required changing the internal representation of sockets to one
773       that remembers (for each socket file descriptor) whether it is currently
774       blocking or non-blocking.  This state is maintained lazily (i.e., a system
775       call is made only if the state actually needs to change).
776    
777    2. OS-specific details of sockets were moved into separate files, thus
778       making it possible to unify the bulk of the socket implementations
779       between Unix and Win32.
780    
781    3. CML's socket API changed accordingly.
782       (Note that we need to remove non-blocking functions from this API
783       since they are redundant in the case of CML!)
784    
785    4. CML's socket implementation now makes use of non-blocking functions
786       provided by Basis, thus removing all OS-dependent code from this part
787       of CML.
788    
789    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

911    as well as under *nix as long as it compiles.
912    
913    Other changes:
914    
915      - made CML compile again under Win32
916      - made eXene compile under Win32 (by providing a fake structure UnixSock
917        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
918      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
919        same as type int;  under Win32 it isn't
920      - fixed some slice-related problems in the win32-specific parts of CML
921      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
922        (under Win32, the volume name is case-insensitive, and the
923        OS.Path code compares volume names for equality)

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

980    Tag: blume-20030828-intinf
981    Description:
982    
983    This is a major update which comes with a version number bump
984    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
985    and an implementation of IntInf in the Basis.
986    
987    There are a fairly large number of related changes and updates throughout
988    the system:
989    
990    Basis:
991            - Implemented IntInf.
992            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
993            - Added some missing Real64 operations, most notably Real.toLargeInt.
994            - Added FixedInt as a synonym for Int32.
995    
996    compiler:
997            * Added support for a built-in intinf type.
998              - literals
999              - pattern matching
1000              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
1001              - overloading on literals and operations
1002    
1003            This required adding a primitive type intinf, some additional
1004            primops, and implementations for several non-trivial intinf
1005            operations in Core.  (The intinf type is completely abstract
1006            to the compiler; all operations get delegated back to the Core.)
1007    
1008            * Intinf equality is handled by polyequal.  However, the compiler
1009            does not print its usual warning in this case (since polyequal
1010            is the right thing to do there).
1011    
1012            * Improved the organization of structure InlineT.
1013    
1014            * A word about conversion primops:
1015            If conversions involving intinf do not cancel out during
1016            CPS contract, then the compiler must insert calls to Core functions.
1017            Since all core access must be resolved already during the FLINT
1018            translate phase, it would be too late a the time of CPS contract
1019            to add new Core calls.  For this reason, conversion primops
1020            for intinf carry two arguments:  1. the numeric argument that
1021            they are supposed to convert, and 2. the Core function that
1022            can help with this conversion if necessary.  If CPS contract
1023            eliminates a primop, then the associated Core function becomes
1024            dead and goes away.  Intinf conversion primops that do not get
1025            eliminated by CPS contract get rewritten into calls of their
1026            core functions by a separate, new phase.
1027    
1028    interactive system:
1029            - Control.Print.intinfDepth controls max length of intinf constants
1030            being printed. (Analogous to Control.Print.stringDepth.)
1031            - Cleanup in printutil and pputil: got rid of unused stuff and
1032            duplicates; replaced some of the code with code that makes better
1033            use of library functionality.
1034    
1035    CM:
1036            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
1037            are no longer silent.
1038    
1039    CKIT:
1040            Fixed mismatched uses of Int32 and LargeInt.  I always decided
1041            in favor of LargeInt -- which is now the same as IntInf.
1042            CKIT-knowledgable people should check whether this is what's
1043            intended and otherwise change things back to using Int32 or
1044            FixedInt.
1045    
1046    Throughout the code:
1047            Started using IntInf.int literals and built-in operations
1048            (e.g., comparison with 0) where this seems appropriate.

1068    Description:
1069    
1070    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
1071    
1072        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
1073    
1074    This patch restores SML/NJ's ability to run under win32.  There are a
1075    number of changes, including fixes for several bugs that had gone
1076    unnoticed until now:
1077    
1078      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
1079        trying to run the win32 version from within cygwin.)
1080    
1081      - There are a number of simple .bat scripts that substitute for their
1082        corresponding Unix shell-scripts.  (See below.)
1083    
1084      - The internals of ml-build have been modified slightly.  The main
1085        difference is that instead of calling ".link-sml" (or link-sml.bat)
1086        using OS.Process.system, the ML process delegates this task back
1087        to the script.  Otherwise problems arise in mixed environments such
1088        as Cygwin where scripts look and work like Unix scripts, but
1089        where OS.Process.system cannot run them.
1090    
1091      - In CM, the srcpath pickler used native pathname syntax -- which
1092        is incorrect in the case of cross-compilation.  The new pickle format
1093        is independent of platform-specific naming conventions.
1094    
1095      - Path configuration files (such as lib/pathconfig) can now choose
1096        between native and standard syntax.  Placing a line of the form
1097    
1098            standard!
1099    
1100        into the file causes all subsequent paths to be interpreted using
1101        CM standard pathname syntax (= Unix conventions); a line
1102    
1103            native!
1104    
1105        switches back to native style.  This was needed so that
1106        path config files can be written portably, see src/system/pathconfig.
1107    
1108      - Runtime system:
1109    
1110          - win32-filesys.c:  get_file_time and set_file_time now
1111            access modification time, not creation time.
1112    
1113          - I/O code made aware of new array representation.
1114    
1115          - Bug fixes in X86.prim.masm.
1116    
1117       - src/system/makeml made aware of win32. (For use under cygwin
1118            and other Unix-environments for windows.)
1119    
1120       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
1121         which caused BinIO.inputAll to fail consistently.
1122    
1123    .bat scripts:
1124    
1125       Windows .bat scripts assume that SMLNJ_HOME is defined.
1126    
1127       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
1128         applications (sml, ml-yacc, ml-lex).
1129       - ml-build.bat: analogous to ml-build.
1130       - config\install.bat:  Analogous to config/install.sh.  This requires
1131         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
1132         (nmake etc. must be on the path, and vcvars32 must have been run.)
1133         Moreover, sources for ml-lex and ml-yacc need to exist under src,
1134         and the bootfile hierarchy must have been unpacked under
1135         sml.boot.x86-win32.
1136         The script is very primitive and does a poor job at error checking.
1137         It only installs the base system, ml-lex, and ml-yacc.  No other
1138         libraries are being installed (i.e., you get only those that
1139         are part of the compiler.)
1140       - link-sml.bat:  analogous to .link-sml, but not currently used
1141    
1142    Unrelated bug fixes:
1143    
1144      - ml-nlffigen now exports structures ST_* corresponding to incomplete
1145        types.
1146      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
1147        otherwise.)

1176         be treated as errors (default is false).
1177      2. Cleaned up the *entire* source tree so that CMB.make goes through
1178         without a single non-exhaustive match- or bind warning.

1186    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
1187    
1188       This mainly affects the quality of error messages.  However, some
1189       of the code is now more straightforward than before. (Treatment of
1190       the above four constructs in translate.sml is much simpler than
1191       the "macro-expansion" that was going on before.  Plus, the mach-
1192       compiler no longer gets invoked just to be able to compile an
1193       if-expression.)
1194    
1195    2. The ErrorMsg.Error exception is now caught and absorbed by the
1196       interactive loop.

1206    
1207       o getnetbyname, getnetbyaddr: these functions seem to be missing in
1208         the Cygwin library.
1209       o Ctrl-C handling may be flaky.
1210       o Windows system calls and Windows I/O are not supported.
1211

1276    
1277    In good old tradition, there has been a slight hiccup so that we have
1278    to patch 110.42 after the fact.   The old release tag has been replaced
1279    (see below).
1280    
1281    The change solves a problem with two competing approaches the
1282    configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
1283    each other's way.
1284    
1285    This change only affects the runtime system code and the installer script.

1353    case.  (The sense of the isNaN test was reversed -- which made min and
1354    max always return their first argument.)

1369    
1370    I back-ported my implementation of IEEEReal.fromString from the
1371    idlbasis-devel branch so that we can test it.
1372    
1373    Another small change is that ppDec tries to give more information
1374    than just "<sig>" in the case of functors.  However, this code is
1375    broken in some mysterious way if the functor's body's signature
1376    has not been declared by ascription but gets inferred from the
1377    implementation.  This needs fixing...

1477    
1478    0. John Reppy made several modifications to the SML/NJ library.
1479       In particular, there is a shiny new controls-lib.cm.
1480    
1481    1. Pushed new controls interface through compiler so that everything
1482       compiles again.
1483    
1484    2. Added FormatComb and FORMAT_COMB to the CML version of the
1485       SML/NJ library (so that CML compiles again).
1486    
1487    3. Modified init scripts because XXX_DEFAULT environment variables
1488       are no longer with us.  (Boot-time initialization is now done
1489       using the same environment variables that are also used for
1490       startup-time initialization of controls.)

1496    Description:
1497    
1498            All pseudo-ops emitted before the first segment declaration
1499    such as TEXT, DATA, and BSS directives are assumed to be global
1500    declarations and are emitted first in the assembly file. This is
1501    useful in a number of situations where one has pseudo-ops that are not
1502    specific to any segment, and also works around the constraint that one
1503    cannot have client pseudo-ops in the TEXT segment.
1504    
1505            Because no segment is associated with these declarations it is
1506    an error to allocate any space or objects before the first segment
1507    directive and an exception will be raised. However, we cannot make
1508    this check for client pseudo-ops.
1509    
1510            These top level declarations are a field in the CFG graph_info.
1511    In theory you can continue to add to this field after the CFG has been
1512    built -- provided you know what you are doing;-)

1535    Description:
1536    
1537    Applied the following bugfix provided by Emden Gansner:
1538    
1539        Output is corrupted when outputSubstr is used rather than output.
1540    
1541        The problem occurs when a substring
1542    
1543            ss = (s, dataStart, dataLen)
1544    
1545        where dataStart > 0, fills a stream buffer with avail bytes left.
1546        avail bytes of s, starting at index dataStart, are copied into the
1547        buffer, the buffer is flushed, and then the remaining dataLen-avail
1548        bytes of ss are copied into the beginning of the buffer. Instead of
1549        starting this copy at index dataStart+avail in s, the current code
1550        starts the copy at index avail.
1551    
1552        Fix:
1553        In text-io-fn.sml, change line 695 from
1554             val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
1555        to
1556             val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

1572    Description:
1573    
1574    Added full support for div/mod/rem/quot on the x86, using the machine
1575    instruction's two results (without clumsily recomputing the remainder)
1576    directly where appropriate.
1577    
1578    Some more extensive power-of-two support was added to the x86 instruction
1579    selector (avoiding expensive divs, mods, and muls where they can be
1580    replaced with cheaper shifts and masks).  However, this sort of thing
1581    ought to be done earlier, e.g., within the CPS optimizer so that
1582    all architectures benefit from it.
1583    
1584    The compiler compiles to a fixed point, but changes might be somewhat
1585    fragile nevertheless.  Please, report any strange things that you might
1586    see wrt. div/mod/quot/rem...

1596    Fast paths (quotient > 0 or remainder = 0) are not affected, though.
1597    The problem was with quotient = 0, because that alone does not tell

1599    remainder and divisor have the same sign...  :(

1608    
1609    NEW BOOTFILES!!!    Version number bumped to 110.39.3.
1610    
1611    Primops have changed. This means that the bin/boot-file formats have
1612    changed as well.
1613    
1614    To make sure that there is no confusion, I made a new version.
1615    
1616    
1617    CHANGES:
1618    
1619    * removed REMT from mltree (remainder should never overflow).
1620    
1621    * added primops to deal with divisions of all flavors to the frontend
1622    
1623    * handled these primops all the way through so they map to their respective
1624      MLRISC support
1625    
1626    * used these primops in the implementation of Int, Int32, Word, Word32
1627    
1628    * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
1629    
1630    * parameterized INLMIN, INLMAX, and INLABS by a numkind
1631    
1632    * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
1633      floating point
1634    
1635    * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
1636      and Real (but Real.abs maps to a separate floating-point-only primop)
1637    
1638    
1639    TODO items:
1640    
1641    * Hacked Alpha32 instruction selection, disabling the selection of REMx
1642      instructions because the machine instruction encoder cannot handle
1643      them.  (Hppa, PPC, and Sparc instruction selection did not handle
1644      REM in the first place, and REM is supported by the x86 machine coder.)
1645    
1646    * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
1647      selection phase.  (The two can be streamlined because the hardware
1648      delivers both quotient and remainder at the same time anyway.)
1649    
1650    * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
1651      (Currently the behavior is inconsistent both across architectures and
1652      wrt. the draft Basis spec.)
1653    
1654    * Word8 should eventually be handled natively, too.
1655    
1656    * There seems to be one serious bug in mltree-gen.sml.  It appears, though,
1657      as if there currently is no execution path that could trigger it in
1658      SML/NJ.  (The assumptions underlying functions arith and promotable do not
1659      hold for things like multiplication and division.)

1664    Tag: blume-20020327-mlrisc-divisions
1665    Description:
1666    
1667    Added support for all four division operations (ML's div, mod, quot,
1668    and rem) to MLRISC.  In the course of doing so, I also rationalized
1669    the naming (no more annoying switch-around of DIV and QUOT), by
1670    parameterizing the operation by div_rounding_mode (which can be either
1671    DIV_TO_ZERO or DIV_TO_NEGINF).
1672    
1673    The generic MLTreeGen functor takes care of compiling all four
1674    operations down to only round-to-zero div.
1675    
1676    Missing pieces:
1677    
1678      * Doing something smarter than relying on MLTreeGen on architectures
1679        like, e.g., the x86 where hardware division delivers both quotient and
1680        remainder at the same time.  With this, the implementation of the
1681        round-to-neginf operations could be further streamlined.
1682    
1683      * Remove inlining support for div/mod/rem from the frontend and replace it
1684        with primops that get carried through to the backend.  Do this for all
1685        int and word types.

1691    Description:
1692    
1693    I improved (hopefully without breaking them) the implementation of Int.div,
1694    Int.mod, and Int.rem.   For this, the code in translate.sml now takes
1695    advantage of the following observations:
1696    
1697      Let  q = x quot y      r = x rem y
1698           d = x div  y      m = x mod y
1699    
1700    where "quot" is the round-to-zero version of integer division that
1701    hardware usually provides.  Then we have:
1702    
1703         r = x - q * y        where neither the * nor the - will overflow
1704         d = if q >= 0 orelse x = q * y then q else q - 1
1705                              where neither the * nor the - will overflow
1706         m = if q >= 0 orelse r = 0 then r else r + y
1707                              where the + will not overflow
1708    
1709    This results in substantial simplification of the generated code.
1710    The following table shows the number of CFG nodes and edges generated
1711    for
1712            fun f (x, y) = x OPER y

1771        * the same as RECORD with tag tag_raw32 (sz=4), or tag_fblock (sz=8)
1772        *)
1773      | RAW_RECORD of {tag:bool,sz:int}
1774      and ccall_type = CCALL_INT32 | CCALL_REAL64 | CCALL_ML_PTR
1775    
1776      2.  These CPS primops are now overloaded:
1777    
1778           rawload of {kind:numkind}
1779           rawstore of {kind:numkind}
1780    
1781          The one argument form is:
1782    
1783             rawload {kind} address
1784    
1785          The two argument form is:
1786    
1787             rawload {kind} [ml object, byte-offset]
1788    
1789      3. RAW_CCALL/RCC now takes two extra arguments:
1790    
1791         a. The first is whether the C call is reentrant, i.e., whether
1792            ML state should be saved and restored.
1793         b. The second argument is a string argument specifying the name of
1794            library and the C function.
1795    
1796         These things are currently not handled in the code generator, yet.
1797    
1798      4. In CProto,
1799    
1800         An encoding type of "bool" means "ml object" and is mapped into
1801         C prototype of PTR.  Note that "bool" is different than "string",
1802         even though "string" is also mapped into PTR, because "bool"
1803         is assigned an CPS type of BOGt, while "string" is assigned INT32t.
1804    
1805      5. Pickler/unpicker
1806    
1807         Changed to handle RAW_RECORD and newest RAW_CCALL
1808    
1809      6. MLRiscGen,
1810    
1811         1. Changed to handle the new rawload/rawstore/rawrecord operators.
1812         2. Code for handling C Calls has been moved to a new module CPSCCalls,
1813            in the file CodeGen/cpscompile/cps-c-calls.sml
1814    
1815      7. Added the conditional move operator
1816    
1817             condmove of branch
1818    
1819         to cps.  Generation of this is still buggy so it is currently
1820         disabled.

1826    Description:
1827    
1828    Implemented the Ball-Larus branch prediction-heuristics, and
1829    incorporated graphical viewers for control flow graphs.
1830    
1831    Ball-Larus Heuristics:
1832    ---------------------
1833    See the file compiler/CodeGen/cpscompile/cpsBranchProb.sml.
1834    
1835    By design it uses the Dempster-Shafer theory for combining
1836    probabilities.  For example, in the function:
1837    
1838        fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)
1839    
1840    the ball-larus heuristics predicts that the n=0 is unlikely
1841    (OH-heuristic), and the 'then' branch is unlikely because of the
1842    RH-heuristic -- giving the 'then' branch an even lower combined
1843    probability using the Dempster-Shafer theory.
1844    
1845    Finally, John Reppy's loop analysis in MLRISC, further lowers the
1846    probability of the 'then' branch because of the loop in the else
1847    branch.
1848    
1849    
1850    Graphical Viewing:
1851    ------------------
1852    I merely plugged in Allen's graphical viewers into the compiler. The
1853    additional code is not much. At the top level, saying:
1854    
1855            Control.MLRISC.getFlag "cfg-graphical-view" := true;
1856    
1857    will display the graphical view of the control flow graph just before
1858    back-patching.  daVinci must be in your path for this to work. If
1859    daVinci is not available, then the default viewer can be changed
1860    using:
1861    
1862            Control.MLRISC.getString "viewer"
1863    
1864    which can be set to "dot" or "vcg" for the corresponding viewers. Of
1865    course, these viewers must be in your path.
1866    
1867    The above will display the compilation unit at the level of clusters,
1868    many of which are small, boring, and un-interesting. Also setting:
1869    
1870            Control.MLRISC.getInt "cfg-graphical-view_size"
1871    
1872    will display clusters that are larger than the value set by the above.
1873
