18    Tag: blume-20041221-longlong
19    Description:
20    
21    * Implemented access to signed and unsigned long long data in NLFFI.
22    (The parameter-passing part of the picture has not complete. But
23    data structure access seems to work.)
24    
25    * Fixed CM's incorrect assumption that the PPC is little-endian.
26      (On the Mac, it is big-endian.  And that's currently our only
27      PPC platform.)

33    Description:
34    
35    Some cleanup in the $c/memory.cm library: separated some concerns by
36    moving allocation code and memory access code each into their own
37    files.

43    Description:
44    
45        The Unix I/O library of SML/NJ on cygwin does not understand
46    Windows style pathname, so problems arise when SMLNJ_HOME is set
47    to a Windows style pathname.  _run-sml now converts SMLNJ_HOME
48    to a POSIX pathname on cygwin.

92    Tag: blume-20041214-spaces
93    Description:
94    
95    Hacked some of the scripts (in particular: the installer) to cope with
96    spaces in filenames a bit better.  But beware: the current "solution"
97    is likely still full of bugs and inherently incomplete.  (We need to
98    do away with those shell scripts for a comprehensive solution.)

121    Description:
122    
123    smlnj-lib:
124    
125      Added function HashString.hashString' for substrings.
126      Hand-inlined CharVector.foldl into HashString (for speed).
127      Modified implementation of structure Atom to avoid extracting
128      strings from substrings unless necessary.

134    Tag: blume-20041124-cml
135    Description:
136    
137    Made sure CML compiles when Position = Int64.
138

140    Name: Matthias Blume (blume (at) tti - c (dot) org)
141    Date: 2004/11/24 14:30:00 CST
142    Tag: blume-20041124-position
143    Description:
144    
145    The compiler can now be compiled in a mode that makes structure Position
146    equal to Int64.  The default, however, is unchanged (Position = Int31)
147    for the time being.
148    
149    To enable 64-bit positions, use the following procedure:
150    
151    1. Start sml
152    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
153    3. Type
154          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
155    4. Run CMB.make() as usual.
156    
157    This is barely tested.  The only test so far was a little SML program
158    counting the number of characters in an 8-gigabyte file by
159    reading it character-by-character.  That test was successful.
160    
161    In support of 64-bit positions, a number of new functions have been
162    added to the runtime system.

168    Description:
169    
170    Fixed a problem with unhelpful error messages related to problems with
171    .cm- or .sml files that appear as part of the sml command line.

202    Tag: blume-20041113-versiontool
203    Description:
204    
205    - Stripped down the versiontool: It now only handles the version number.
206      The date string is generated at bootstrap time (during makeml).
207    
208    - In a previous commit, fixed a minor issue with how polyequal is being
209      translated.  In particular, the code now "looks through" abstractions.
210      This results in slightly fewer polyEqual warnings and hopefully slightly
211      more efficient code.  Important examples for where this matters are
212      the new int64 and word64 types.

226    Tag: blume-20041111-more64
227    Description:
228    
229    All the pieces of Word64 are now there, with the exception of the
230    conversions from and to LargeWord. (Eventually these need to be identities,
231    but for the time being they don't even make sense because LargeWord is
232    32-bit wide.)
233    
234    Also started to add similar support for Int64, but major pieces of that
235    are still missing.
236    
237    ----------------------------------------------------------------------
238    Name: Matthias Blume (blume (at) tti - c (dot) org)
239    Date: 2004/11/11 00:15:00 CST
240    Tag: blume-20041111-word64
241    Description:
242    
243    Structure Word64 is now (almost) complete, word literals and patterns
244    seem to work.  There are a few odd pieces missing.  In particular,
245    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
246    at the moment.
247    
248    Making Word64 official would mean that LargeWord becomes Word64.  But
249    this requires extreme care because most word-word conversions have to
250    go through LargeWord, so making a mistake means loss of efficiency or
251    worse.  Eventually there will be a solution similar to (but actually
252    simpler than) what I did with IntInf.

258    Description:

260    More 64-bit hacking (but still not even half-way there yet).
261    Also, some assorted improvements to the handling of 8-bit words.

278    New working version (110.50).  NEW BOOTFILES!
279    
280                 =====================
281    
282    Also:
283    
284      - Changend config/srcarchiveurl from a file just
285        containing the URL string into a file containing
286        shell script code.  The code has access to the $VERSION variable.
287      - Made corresponding changes to config/install.sh and config/unpack.
288      - Default contents of config/srcarchiveurl uses $VERSION and
289        normally does not have to be edited to reflect a version change.
290    
291      (As a result, a version change can be done by just editing
292       config/version, the rest is now automatic.)

307    Description:
308    
309    This is the HISTORY entry for two earlier commits, both concerning
310    the x86 c-calls code in MLRISC:
311    
312      - added a missing LOAD in the code that deals with struct arguments
313      - made sure the caller does not add the wrong number of bytes to the
314        stack pointer after a call of a function returning a struct
315        (the callee already pops the implicit argument which points to
316         the space reserved for the result)

332    Tag: blume-20041020-standalone-backtrace
333    Description:
334    
335    Added a mechanism for getting back-trace information from standalone
336    programs.  Here is how it works:
337    
338       1. The part of the program from which you want to get backtrace
339          information (usually the whole program) should be wrapped with
340          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
341          main program could be modified from something like
342    
343             fun main (pgm, args) = ...
344    
345         to
346    
347            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
348    
349       2. To be able to access BackTrace.monitor, you have to add
350          library $smlnj-tdp/plugins.cm to the .cm file that contains your
351          main function.
352    
353       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
354          CM might have created in the past for your project).
355    
356       4. Build the system using this command line:
357    
358             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
359                      myprog.cm MyProg.main myprog
360    
361          instead of the usual
362    
363             ml-build myprog.cm MyProg.main myprog
364    
365    I changed a library name:
366    
367       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
368    
369    New libraries:
370    
371       $smlnj-tdp/back-trace.cm
372          -- when loaded causes the back-trace plugin to be installed
373       $smlnj-tdp/coverage.cm
374          -- when loaded causes the coverage plugin to be installed

389    Tag: blume-20041015-coverage
390    Description:
391    
392    * Test coverage tool added!
393    * Further reorganization of tracing-, debugging-, and profiling support:
394    
395        - moved original BTImp -- now called BackTrace -- into a separate
396          library called $/trace-debug-profile.cm
397        - eliminated all mentions of BTrace from SMLofNJ.Internals
398        - only the instrumentation mechanism is now left in the compiler proper
399        - BackTrace module is a plugin which is NOT plugged in by default
400        - Coverage module is another such plugin
401    
402    To get the benefits of any of these plugin modules, the code in
403    question must be compiled with tdp instrumentation turned on.  This
404    can be done by setting SMLofNJ.Internals.TDP.mode to true.
405    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
406    
407    Plugins are selected at link time.  (Pre-compiled instrumented code
408    can be re-loaded with different plugins in effect.)  When an
409    instrumented module is linked, whatever plugins are at that time
410    enabled will come into effect for that module.
411    
412    To enable the back-trace plugin, load library $/trace-debug-profile.cm
413    and invoke BackTrace.install() (e.g., from the interactive prompt).
414    To enable the coverage plugin, load the same library and invoke
415    Coverage.install().
416    
417    Back-traces are generated automatically on uncaught exceptions and
418    when the code in question explicitly invokes BackTrace.trigger().
419    
420    Coverage (and execution frequency-) information must be queried
421    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

436    Description:
437    
438    Some rationalization of names:
439    
440       structure BTrace -> structure TDPInstrument
441       etc.
442    
443    This is is preparation of using the original back-trace
444    instrumentation for other purposes.  "TDP" stands for
445    Trace/Debug/Profile.
446    
447    The control flag controlling whether instrumentation is on or off is now
448    registered under a different name, so instead of running sml as
449    
450     sml -Cinstrument.btrace-mode=true
451    
452    one has to say
453    
454     sml -Ctdp.instrument=true

472    Fixed handling of keywords in .cm files: After seeing "is" the lexer
473    treats subsequent occurrences of "group", "library", "source", "is",
474    "*", and "-" as ordinary identifiers rather than keywords.
475    
476    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
477    is supposed to accept a tool argument called "source", but this did
478    not work because of the clash with the keyword.

515    attached.  I don't know if this is worth fixing...)

521    Description:
522    
523    * Moved the "version" magic into its own little library under
524      src/system/smlnj/internal.  This avoids expensive reconstruction of
525      a stable src/compiler/core.cm.
526    
527    * At the same time, structure CompilerVersion is now known as
528      structure SMLNJVersion.
529    
530    * Arranged for the version tool to NOT kick in when rebuilding the system
531      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
532      Also, loading the versiontool does not work when rebuilding the system
533      because CM is not properly initialized at that time.

539    Description:
540    
541    Implemented some CM magic to have
542        file src/compiler/TopLevel/main/version.sml
543    generated automagically.
544    The version is taken from two files: config/version and config/release.
545    The first is expected to contain a two-part version number such as 110.49.
546    The second should contain a single number, but it may be missing.
547    
548    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
549    time the version tool is loaded (which is the first time you say CMB.make),
550    then the tool will increment the value stored in config/release every
551    time CMB.make is invoked.
552    
553    The binfile format is now insensitive to anything beyond the first
554    two components of a version number, so bumping the release does not render
555    binfiles incompatible.  Auto-bumping can be used to keep track of versions
556    during development without invalidating existing binfiles.
557    
558    In any case, every CMB.make updates the date information in version.sml.
559    (This is the date that is printed in the banner.)

572    Tag: blume-20040927-controls
573    Description:
574    
575    Added two pieces of functionality to the Controls interface:
576    
577    1.   val save'restore: 'a control -> unit -> unit
578    
579       grabs the current value of the control in stage 1 and restores it
580       in stage 2.
581    
582    2.   val set' : 'a control * 'a -> unit -> unit
583    
584       stores the given value into the control in stage 2 (i.e., delayed)
585       but does all error checking in stage 1.
586       (This is for string controls that need to do parse their argument --
587        something that might fail.  In some cases, notably in CM, one
588        already knows the intended argument but wants to delay the actual
589        assignment until a time when error recovery would be more difficult.)
590    
591    Changed the handling of controls in tool arguments to classes "sml" and
592    "lazysml":
593       - use Controls.save'restore as a more robust way of restoring the
594         old value (in particular: without having to re-parse the string)
595       - use controls to handle the "overload" keyword in the init group
596         (I believe this change actually fixes a long-standing obscure bug.)

601    Tag: blume-20040927-lazysml
602    Description:
603    
604    Added a new tool class called "lazysml" to CM's tool chest.  The only
605    difference to "sml" is that compilation is done with Control.lazysml
606    set to true.  A source of class "lazysml" is automatically recognized
607    by a file name suffix of ".lml".
608    
609    In addition to the above feature, the original class "sml" now also
610    supports a tool argument "lazy" which has the same effect.  As a
611    result, the following three lines are equivalent:
612    
613        foo.sml : lazysml
614        foo.sml : sml (lazy)
615        foo.sml (lazy)
616    
617    The setting goes into effect both during parsing and during
618    compilation.  The original setting is restored right after parsing and
619    after compilation, respectively.
620    
621    In addition to all the above, there is also a general mechanism to set
622    ANY of the "controls" that are available at the command line via
623    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
624    apply as well. (In fact, "lazy" is implemented as a special case of
625    the general mechanism.)
626    
627    The .cm file syntax uses a new keyword tool argument called "with".
628    There are several ways of indicating the desired settings:
629    
630        foo.sml (with:parser.quotations=true)
631        foo.sml (with:(name:parser.quotations value:true))
632        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
633        foo.sml (with:(name1=value1 name2=value2 ...))
634        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
635    
636        etc.
637    
638    Another possible abbreviation is to leave out the =v or value:v part
639    if the name refers to a boolean control (in which case the value is
640    taken to be true).  Thus, one could get lazy sml also by saying:
641    
642        foo.sml (with:parser.lazy-keyword=true)
643        foo.sml (with:parser.lazy-keyword)
644        foo.sml (with:(name:parser.lazy-keyword value:true))
645        foo.sml (with:(name:parser.lazy-keyword))

944    - use paramAlloc to report c-calls with too many arguments
945      (for PPC version where parameter area is pre-allocated)
946    - added ccall_maxargspace to machspec (to implement the above)
947    - made "make" commend in CM's "make" tool configurable
948    - added option (default: on) for passing the name of the SML/NJ's "bin"
949      directory to "make"; the call looks like this:
950    
951         make <options> SMLNJ_BINDIR=<dir> <target>
952    
953      This can be used by the Makefile to, e.g., pick the "right" version

963    NLFFI under Mac OS X now working (sort of).  This is largely untested,
964    though.
965    
966    Note:  1. You have to make a new, clean build of the runtime system.
967           2. There are new BOOTFILES, you have to use them!
968              (Doing the bootstrap process yourself would be *very* painful!
969               If you absolutely have to do it, build the system under
970               a different architecture and then cross-compile.)
971    
972    Version bumped to 110.46.1 to account for runtime data format changes.

996    Tag: blume-20040617-timer-unix
997    Description:
998    
999    Changed the interface of structures Timer and Unix to match the most
1000    recent Basis spec.
1001    
1002    In the case of Unix there still seems to be an open/weird issue:
1003    
1004       The {text,bin}{In,Out}streamOf functions are supposed to create
1005       fresh streams whenever they are called -- as opposed to have them
1006       return the same stream every time.  This design is supposed to
1007       prevent space leaks caused by proc values hanging on to streams.
1008    
1009       The reap function, on the other hand, is supposed to close the
1010       streams.  This cannot be done without having a handle on the
1011       stream in proc after all...
1012    
1013    I took the liberty to implement the following stopgap solution:
1014    
1015      The proc value hangs on to the most recently created stream(s).
1016      Reap closes those.  If either or both of the two streams hadn't
1017      been created at all yet, then reap will close the corresponding
1018      file descriptors directly.
1019    
1020    PS: I don't understand the original space leak argument anymore.  If
1021    a proc hangs on to the imperative stream, then I/O operations on those
1022    will advance the state of the cached stream and avoid the space leak.

1035    Tag: blume-20040525-group-owner
1036    Description:
1037    
1038    CM now ignores (but still accepts) the "owner" information in group
1039    descriptions.  The owner of a group is its next enclosing
1040    library. Each group must have a unique owner.  (There is a virtual
1041    "toplevel" library that owns groups which are not nested within a real
1042    library.)  Previously, each group had to explicitly declare its owner,
1043    and CM would check that such a declaration is correct.  The new scheme
1044    is to have CM check that for each group there is precisely one owning
1045    library.
1046    
1047    The advantage of the new scheme is that the programmer no longer needs
1048    to maintain the somewhat annoying owner information.  The downside is
1049    that CM cannot enforce the ownership rule across multiple runs of
1050    CM.make.  Fortunately, enclosing the same group in two different
1051    libraries A and B which are not part of the same program does not
1052    cause real problems.

1071    Description:
1072    
1073    Arranged for ml-build to clean up after itself a little bit better.
1074    The script generates a temporary SML source file and compiles it using
1075    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
1076    gets rid of those at the end, so they don't accumulate under .cm.
1077    
1078    This required a minor change to install.sh because the name of the
1079    metadata directory (default: .cm) is actually configurable at
1080    installation time.

1095    Description:
1096    
1097    Added previously missing support for many socket-related functions
1098    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
1099    for the voluminous patch!
1100    
1101    (I have not tested this patch under win32 yet.)
1102    
1103    Here is David's e-mail:
1104    
1105    Hi,
1106    
1107    Attached to this email you find a diff against sml/nj 110.45
1108    that will enable socket support under Windows.
1109    
1110    To apply the patch (using unix or cygwin)
1111    1) gunzip runtime.diff.gz
1112    2) "cd" into "src/runtime" in the source tree of a fresh
1113       110.45 installation.
1114    3) patch -p 1 < [your/path/to]runtime.diff
1115    
1116    The code compiles fine but has NOT yet been extensively tested.
1117    I only ran a few tests for basic socket client functionality
1118    (which worked fine).  Especially the functions that use ioctl
1119    are not tested at all and might not work (see below).
1120    
1121    I implemented this since we want to move to a newer version of sml/nj
1122    but need socket support in order to use it.  This is the first time I
1123    even had a look at the sml/nj source,  so please review my changes
1124    before making this part of the distribution!  Here are a few issues
1125    that I think might be better for someone to solve who is more
1126    familiar with the sml/nj source (and socket programming):
1127    
1128    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
1129      exception since I could not figure out what the windows equivalent
1130      of these functions is
1131    
1132    - In sockets-osdep.h there are a some #include statements that are
1133      only used in a few files that include sockets-osdep.h
1134    
1135    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
1136      does not process its return value since I don't know how to
1137      report an error upwards.
1138    
1139    - It would probably be good to have a call to WSACleanup() when
1140      the library is unloaded (if there is such a possibility).
1141      Otherwise I think Windows will take care of this automatically
1142      when the process finishes.
1143    
1144    - I used ioctlsocket() as a replacement for ioctl() but I have
1145      no idea if that is actually the proper replacement on Windows.
1146    
1147    - All these issues are marked in the code by "FIXME" comments.
1148    
1149    We use sml/nj extensively in our products and are quite happy
1150    with it.  I hope this contribution will help you.
1151    
1152    Keep up the good work!
1153    
1154    David

1193    everything.  (Notice that this refers to source code only.  Compiled
1194    code is still only installed for modules that were requested explicitly
1195    or which are required for other modules that were requested explicitly.)

1229    Description:

1231    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
1232    of SML/NJ.  The problem is that
1233    
1234       lib = dlopen(NULL, ...)
1235       f   = dlsym(lib, "malloc");
1236    
1237    does not work on Windows unless we explicitly export symbols
1238    such as 'malloc' during linking.  We fixed this by explicitly
1239    exporting the required symbols with the magic gcc incantation:
1240    
1241        -Wl,--export-all cygwin.def
1242    
1243    where cygwin.def is a file containing all the symbols that
1244    we wish to export.
1245    
1246    I suspect this is a Windows problem and we'll have to
1247    do the same (somehow with windows compilers) when
1248    we build the native win32 version with the system
1249    calls LoadLibrary/GetProcAddress.

1375    Description:
1376    
1377    I modified the read-eval-print loop so that the autoloader gets
1378    invoked whenever the prettyprinter tries to look up a symbol that
1379    is not currently defined in the toplevel environment but which
1380    appears in CM's autoload registry.  As a result, we see far fewer of
1381    those ?.Foo.Bar.xxx names in the prettyprinter's output.
1382    
1383    In addition to this I tried to clean up some pieces of the Basis
1384    implementation (e.g., Socket, Word8Array) in order to prevent other
1385    instances of these ?.Foo.Bar.xxx names from being printed.
1386    
1387    The mechanism that picks names for types still needs some work, though.
1388    (Right now it seems that if there is a type A.t which is defined to
1389    be B.u, but B is unavailable at toplevel, then A.t gets printed as
1390    "?.B.u" although the perhaps more sensible solution would be to use
1391    "A.t" in this case.  In other words, the prettyprinter should follow
1392    a chain of DEFtycs not farther than there are corresponding toplevel
1393    names in the current environment.)

1399    Description:
1400    
1401    Another installer tweak:  All the ML code for the installer is now
1402    compiled during CMB.make and put into a little library called
1403    $smlnj/installer.cm.  The installation then simply invokes
1404    
1405       sml -m $smlnj/installer.cm
1406    
1407    and everything happens automagically.
1408    
1409    Win32:  ML code senses value of environment variable SMLNJ_HOME.
1410    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
1411            and BINDIR.
1412    
1413    The new scheme guarantees that the ML code responsible for the installation
1414    is in sync with the APIs of the main system.  Also, the installer is
1415    somewhat faster because the installer script is precompiled.

1426    implementations of non-blocking operations from CML's Socket
1427    structure.

1433    Description:
1434    
1435    1. Fixed SOCKET API and implementation to match Basis spec.
1436       This required changing the internal representation of sockets to one
1437       that remembers (for each socket file descriptor) whether it is currently
1438       blocking or non-blocking.  This state is maintained lazily (i.e., a system
1439       call is made only if the state actually needs to change).
1440    
1441    2. OS-specific details of sockets were moved into separate files, thus
1442       making it possible to unify the bulk of the socket implementations
1443       between Unix and Win32.
1444    
1445    3. CML's socket API changed accordingly.
1446       (Note that we need to remove non-blocking functions from this API
1447       since they are redundant in the case of CML!)
1448    
1449    4. CML's socket implementation now makes use of non-blocking functions
1450       provided by Basis, thus removing all OS-dependent code from this part
1451       of CML.
1452    
1453    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

1566    Description:
1567    
1568    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
1569    Modified config/install.bat to take advantage of it.  Also modified
1570    config/install.sh (and called it config/new-install.sh) to take advantage
1571    of it on Unix systems.  (The SML code is (supposed to be) platform-
1572    independent.)
1573    
1574    The installer can now install everything under Win32
1575    as well as under *nix as long as it compiles.
1576    
1577    Other changes:
1578    
1579      - made CML compile again under Win32
1580      - made eXene compile under Win32 (by providing a fake structure UnixSock
1581        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
1582      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
1583        same as type int;  under Win32 it isn't
1584      - fixed some slice-related problems in the win32-specific parts of CML
1585      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
1586        (under Win32, the volume name is case-insensitive, and the
1587        OS.Path code compares volume names for equality)

1604    Description:
1605    
1606      1. Changed interface to vectors and arrays in Basis to match
1607         (draft) Basis spec.
1608      2. Added signatures and implementations of slices according to
1609         Basis spec.
1610      3. Edited source code throughout the system to make it compile again
1611         under 1. and 2.  (In some cases code had to be added to have it
1612         match the new signatures.)
1613      4. MLRISC should be backward-compatible: the copies of the originals
1614         of files that needed to change under 3. were retained, the .cm files
1615         check the compiler version number and use old versions when
1616         appropriate.
1617      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
1618         dirstream -> string option (in accordance with Basis spec).
1619      6. When generating code that counts lines, ml-lex used function
1620         CharVector.foldli, taking advantage of its old interface.
1621         This has been replaced with the corresponding code from
1622         CharVectorSlice.  (html-lex must be re-lexed!)
1623      7. BitArray in smlnj-lib/Util has been extended/modified to match the
1624         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
1625      8. Removed temporary additions (fromInternal, toInternal) from the
1626         (now obsolete) IntInf in smlnj-lib/Util.
1627      9. Cleaned up structure Byte.
1628     10. Added localOffset, scan, and fromString to Date (according to spec).
1629         Cleaned/corrected implementation of Date.
1630         (Still need to check for correctness; implement better canonicalizeDate.)
1631     11. Added "scan" to signature IEEE_REAL.
1632     12. Some improvements to IntInf [in particular: efficiency-hack for
1633         mod and rem when second operand is 2 (for parity checks).]
1634     13. Changed representation of type Time.time, using a single IntInf.int
1635         value counting microseconds.  This considerably simplified the
1636         implementation of structure Time.  We now support negative time
1637         values; scan and fromString handle signs.
1638     14. Functor PrimIO now takes two additional arguments (VectorSlice and
1639         ArraySlice).

1645    Description:
1646    
1647    This is a major update which comes with a version number bump
1648    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
1649    and an implementation of IntInf in the Basis.
1650    
1651    There are a fairly large number of related changes and updates throughout
1652    the system:
1653    
1654    Basis:
1655            - Implemented IntInf.
1656            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
1657            - Added some missing Real64 operations, most notably Real.toLargeInt.
1658            - Added FixedInt as a synonym for Int32.
1659    
1660    compiler:
1661            * Added support for a built-in intinf type.
1662              - literals
1663              - pattern matching
1664              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
1665              - overloading on literals and operations
1666    
1667            This required adding a primitive type intinf, some additional
1668            primops, and implementations for several non-trivial intinf
1669            operations in Core.  (The intinf type is completely abstract
1670            to the compiler; all operations get delegated back to the Core.)
1671    
1672            * Intinf equality is handled by polyequal.  However, the compiler
1673            does not print its usual warning in this case (since polyequal
1674            is the right thing to do there).
1675    
1676            * Improved the organization of structure InlineT.
1677    
1678            * A word about conversion primops:
1679            If conversions involving intinf do not cancel out during
1680            CPS contract, then the compiler must insert calls to Core functions.
1681            Since all core access must be resolved already during the FLINT
1682            translate phase, it would be too late a the time of CPS contract
1683            to add new Core calls.  For this reason, conversion primops
1684            for intinf carry two arguments:  1. the numeric argument that
1685            they are supposed to convert, and 2. the Core function that
1686            can help with this conversion if necessary.  If CPS contract
1687            eliminates a primop, then the associated Core function becomes
1688            dead and goes away.  Intinf conversion primops that do not get
1689            eliminated by CPS contract get rewritten into calls of their
1690            core functions by a separate, new phase.
1691    
1692    interactive system:
1693            - Control.Print.intinfDepth controls max length of intinf constants
1694            being printed. (Analogous to Control.Print.stringDepth.)
1695            - Cleanup in printutil and pputil: got rid of unused stuff and
1696            duplicates; replaced some of the code with code that makes better
1697            use of library functionality.
1698    
1699    CM:
1700            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
1701            are no longer silent.
1702    
1703    CKIT:
1704            Fixed mismatched uses of Int32 and LargeInt.  I always decided
1705            in favor of LargeInt -- which is now the same as IntInf.
1706            CKIT-knowledgable people should check whether this is what's
1707            intended and otherwise change things back to using Int32 or
1708            FixedInt.
1709    
1710    Throughout the code:
1711            Started using IntInf.int literals and built-in operations
1712            (e.g., comparison with 0) where this seems appropriate.

1733    
1734    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
1735    
1736        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
1737    
1738    This patch restores SML/NJ's ability to run under win32.  There are a
1739    number of changes, including fixes for several bugs that had gone
1740    unnoticed until now:
1741    
1742      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
1743        trying to run the win32 version from within cygwin.)
1744    
1745      - There are a number of simple .bat scripts that substitute for their
1746        corresponding Unix shell-scripts.  (See below.)
1747    
1748      - The internals of ml-build have been modified slightly.  The main
1749        difference is that instead of calling ".link-sml" (or link-sml.bat)
1750        using OS.Process.system, the ML process delegates this task back
1751        to the script.  Otherwise problems arise in mixed environments such
1752        as Cygwin where scripts look and work like Unix scripts, but
1753        where OS.Process.system cannot run them.
1754    
1755      - In CM, the srcpath pickler used native pathname syntax -- which
1756        is incorrect in the case of cross-compilation.  The new pickle format
1757        is independent of platform-specific naming conventions.
1758    
1759      - Path configuration files (such as lib/pathconfig) can now choose
1760        between native and standard syntax.  Placing a line of the form
1761    
1762            standard!
1763    
1764        into the file causes all subsequent paths to be interpreted using
1765        CM standard pathname syntax (= Unix conventions); a line
1766    
1767            native!
1768    
1769        switches back to native style.  This was needed so that
1770        path config files can be written portably, see src/system/pathconfig.
1771    
1772      - Runtime system:
1773    
1774          - win32-filesys.c:  get_file_time and set_file_time now
1775            access modification time, not creation time.
1776    
1777          - I/O code made aware of new array representation.
1778    
1779          - Bug fixes in X86.prim.masm.
1780    
1781       - src/system/makeml made aware of win32. (For use under cygwin
1782            and other Unix-environments for windows.)
1783    
1784       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
1785         which caused BinIO.inputAll to fail consistently.
1786    
1787    .bat scripts:
1788    
1789       Windows .bat scripts assume that SMLNJ_HOME is defined.
1790    
1791       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
1792         applications (sml, ml-yacc, ml-lex).
1793       - ml-build.bat: analogous to ml-build.
1794       - config\install.bat:  Analogous to config/install.sh.  This requires
1795         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
1796         (nmake etc. must be on the path, and vcvars32 must have been run.)
1797         Moreover, sources for ml-lex and ml-yacc need to exist under src,
1798         and the bootfile hierarchy must have been unpacked under
1799         sml.boot.x86-win32.
1800         The script is very primitive and does a poor job at error checking.
1801         It only installs the base system, ml-lex, and ml-yacc.  No other
1802         libraries are being installed (i.e., you get only those that
1803         are part of the compiler.)
1804       - link-sml.bat:  analogous to .link-sml, but not currently used
1805    
1806    Unrelated bug fixes:
1807    
1808      - ml-nlffigen now exports structures ST_* corresponding to incomplete
1809        types.
1810      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
1811        otherwise.)

1837    Two changes:

1839      1. Added a flag for controlling whether non-exhaustive bindings will
1840         be treated as errors (default is false).
1841      2. Cleaned up the *entire* source tree so that CMB.make goes through
1842         without a single non-exhaustive match- or bind warning.

1848    Description:
1849    
1850    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
1851    
1852       This mainly affects the quality of error messages.  However, some
1853       of the code is now more straightforward than before. (Treatment of
1854       the above four constructs in translate.sml is much simpler than
1855       the "macro-expansion" that was going on before.  Plus, the mach-
1856       compiler no longer gets invoked just to be able to compile an
1857       if-expression.)
1858    
1859    2. The ErrorMsg.Error exception is now caught and absorbed by the
1860       interactive loop.

1866    Description:
1867    
1868        Ported the runtime system to cygwin, which uses the unix
1869    x86-unix bin files.  Missing/buggy features:
1870    
1871       o getnetbyname, getnetbyaddr: these functions seem to be missing in
1872         the Cygwin library.
1873       o Ctrl-C handling may be flaky.
1874       o Windows system calls and Windows I/O are not supported.
1875    
1876       A new set of binfiles is located at:
1877    
1878         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
1879    
1880       This is only needed for bootstrapping the cygwin version of smlnj.
1881       Other x86 versions can use the existing binfiles.

1911    110.37 and 110.38.)
1912    There was another set of potential problems related to the handling of
1913    MLRISC annotations (but those did not yet cause real problems, apparently).

1939    Description:
1940    
1941    In good old tradition, there has been a slight hiccup so that we have
1942    to patch 110.42 after the fact.   The old release tag has been replaced
1943    (see below).
1944    
1945    The change solves a problem with two competing approaches the
1946    configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
1947    each other's way.
1948    
1949    This change only affects the runtime system code and the installer script.
1950    (No new bootfiles.)

1974    Description:
1975    
1976    Sml now senses the SMLNJ_HOME environment variable.  If this is set,
1977    then the bin dir is assumed to be in $SMLNJ_HOME/bin and (unless
1978    CM_PATHCONFIG is also set), the path configuration file is assumed
1979    to be in $SMLNJ_HOME/lib/pathconfig.  This way one can easily move
1980    the entire tree to some other place and everything will "just work".
1981    
1982    (Companion commands such as ml-build and ml-makedepend also sense this
1983    variable.)

2037    Another small change is that ppDec tries to give more information
2038    than just "<sig>" in the case of functors.  However, this code is
2039    broken in some mysterious way if the functor's body's signature
2040    has not been declared by ascription but gets inferred from the
