19    Description:
20    
21        The Unix I/O library of SML/NJ on cygwin does not understand
22    Windows style pathname, so problems arise when SMLNJ_HOME is set
23    to a Windows style pathname.  _run-sml now converts SMLNJ_HOME
24    to a POSIX pathname on cygwin.

69    Description:
70    
71    Hacked some of the scripts (in particular: the installer) to cope with
72    spaces in filenames a bit better.  But beware: the current "solution"
73    is likely still full of bugs and inherently incomplete.  (We need to
74    do away with those shell scripts for a comprehensive solution.)

99    smlnj-lib:
100    
101      Added function HashString.hashString' for substrings.
102      Hand-inlined CharVector.foldl into HashString (for speed).
103      Modified implementation of structure Atom to avoid extracting
104      strings from substrings unless necessary.

112    
113    Made sure CML compiles when Position = Int64.

118    Tag: blume-20041124-position
119    Description:
120    
121    The compiler can now be compiled in a mode that makes structure Position
122    equal to Int64.  The default, however, is unchanged (Position = Int31)
123    for the time being.
124    
125    To enable 64-bit positions, use the following procedure:
126    
127    1. Start sml
128    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
129    3. Type
130          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
131    4. Run CMB.make() as usual.
132    
133    This is barely tested.  The only test so far was a little SML program
134    counting the number of characters in an 8-gigabyte file by
135    reading it character-by-character.  That test was successful.
136    
137    In support of 64-bit positions, a number of new functions have been
138    added to the runtime system.

147    .cm- or .sml files that appear as part of the sml command line.

178    Tag: blume-20041113-versiontool
179    Description:
180    
181    - Stripped down the versiontool: It now only handles the version number.
182      The date string is generated at bootstrap time (during makeml).
183    
184    - In a previous commit, fixed a minor issue with how polyequal is being
185      translated.  In particular, the code now "looks through" abstractions.
186      This results in slightly fewer polyEqual warnings and hopefully slightly
187      more efficient code.  Important examples for where this matters are
188      the new int64 and word64 types.

202    Tag: blume-20041111-more64
203    Description:
204    
205    All the pieces of Word64 are now there, with the exception of the
206    conversions from and to LargeWord. (Eventually these need to be identities,
207    but for the time being they don't even make sense because LargeWord is
208    32-bit wide.)
209    
210    Also started to add similar support for Int64, but major pieces of that
211    are still missing.
212

215    Date: 2004/11/11 00:15:00 CST
216    Tag: blume-20041111-word64
217    Description:
218    
219    Structure Word64 is now (almost) complete, word literals and patterns
220    seem to work.  There are a few odd pieces missing.  In particular,
221    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
222    at the moment.
223    
224    Making Word64 official would mean that LargeWord becomes Word64.  But
225    this requires extreme care because most word-word conversions have to
226    go through LargeWord, so making a mistake means loss of efficiency or
227    worse.  Eventually there will be a solution similar to (but actually
228    simpler than) what I did with IntInf.

234    Description:

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

255    
256                 =====================
257    
258    Also:
259    
260      - Changend config/srcarchiveurl from a file just
261        containing the URL string into a file containing
262        shell script code.  The code has access to the $VERSION variable.
263      - Made corresponding changes to config/install.sh and config/unpack.
264      - Default contents of config/srcarchiveurl uses $VERSION and
265        normally does not have to be edited to reflect a version change.
266    
267      (As a result, a version change can be done by just editing
268       config/version, the rest is now automatic.)

283    Description:
284    
285    This is the HISTORY entry for two earlier commits, both concerning
286    the x86 c-calls code in MLRISC:
287    
288      - added a missing LOAD in the code that deals with struct arguments
289      - made sure the caller does not add the wrong number of bytes to the
290        stack pointer after a call of a function returning a struct
291        (the callee already pops the implicit argument which points to
292         the space reserved for the result)

308    Tag: blume-20041020-standalone-backtrace
309    Description:
310    
311    Added a mechanism for getting back-trace information from standalone
312    programs.  Here is how it works:
313    
314       1. The part of the program from which you want to get backtrace
315          information (usually the whole program) should be wrapped with
316          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
317          main program could be modified from something like
318    
319             fun main (pgm, args) = ...
320    
321         to
322    
323            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
324    
325       2. To be able to access BackTrace.monitor, you have to add
326          library $smlnj-tdp/plugins.cm to the .cm file that contains your
327          main function.
328    
329       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
330          CM might have created in the past for your project).
331    
332       4. Build the system using this command line:
333    
334             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
335                      myprog.cm MyProg.main myprog
336    
337          instead of the usual
338    
339             ml-build myprog.cm MyProg.main myprog
340    
341    I changed a library name:
342    
343       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
344    
345    New libraries:
346    
347       $smlnj-tdp/back-trace.cm
348          -- when loaded causes the back-trace plugin to be installed
349       $smlnj-tdp/coverage.cm
350          -- when loaded causes the coverage plugin to be installed

365    Tag: blume-20041015-coverage
366    Description:
367    
368    * Test coverage tool added!
369    * Further reorganization of tracing-, debugging-, and profiling support:
370    
371        - moved original BTImp -- now called BackTrace -- into a separate
372          library called $/trace-debug-profile.cm
373        - eliminated all mentions of BTrace from SMLofNJ.Internals
374        - only the instrumentation mechanism is now left in the compiler proper
375        - BackTrace module is a plugin which is NOT plugged in by default
376        - Coverage module is another such plugin
377    
378    To get the benefits of any of these plugin modules, the code in
379    question must be compiled with tdp instrumentation turned on.  This
380    can be done by setting SMLofNJ.Internals.TDP.mode to true.
381    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
382    
383    Plugins are selected at link time.  (Pre-compiled instrumented code
384    can be re-loaded with different plugins in effect.)  When an
385    instrumented module is linked, whatever plugins are at that time
386    enabled will come into effect for that module.
387    
388    To enable the back-trace plugin, load library $/trace-debug-profile.cm
389    and invoke BackTrace.install() (e.g., from the interactive prompt).
390    To enable the coverage plugin, load the same library and invoke
391    Coverage.install().
392    
393    Back-traces are generated automatically on uncaught exceptions and
394    when the code in question explicitly invokes BackTrace.trigger().
395    
396    Coverage (and execution frequency-) information must be queried
397    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

412    Description:
413    
414    Some rationalization of names:
415    
416       structure BTrace -> structure TDPInstrument
417       etc.
418    
419    This is is preparation of using the original back-trace
420    instrumentation for other purposes.  "TDP" stands for
421    Trace/Debug/Profile.
422    
423    The control flag controlling whether instrumentation is on or off is now
424    registered under a different name, so instead of running sml as
425    
426     sml -Cinstrument.btrace-mode=true
427    
428    one has to say
429    
430     sml -Ctdp.instrument=true

445    Tag: blume-20041008-cmkw
446    Description:
447    
448    Fixed handling of keywords in .cm files: After seeing "is" the lexer
449    treats subsequent occurrences of "group", "library", "source", "is",
450    "*", and "-" as ordinary identifiers rather than keywords.
451    
452    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
453    is supposed to accept a tool argument called "source", but this did
454    not work because of the clash with the keyword.

475    
476    Cleaned up the absyn to reflect the invariant that HANDLE always
477    carries a FNexp as part of the type definition.  This eliminates some
478    superfluous sanity checks at runtime down the road.
479    
480    Some minor cleanup of the btrace code.

488    Added hack to make slave mode work in the presence of the version
489    tool.  (Still, since the master does two passes over the code for
490    CMB.make, the release number gets bumped twice when slaves are
491    attached.  I don't know if this is worth fixing...)

497    Description:
498    
499    * Moved the "version" magic into its own little library under
500      src/system/smlnj/internal.  This avoids expensive reconstruction of
501      a stable src/compiler/core.cm.
502    
503    * At the same time, structure CompilerVersion is now known as
504      structure SMLNJVersion.
505    
506    * Arranged for the version tool to NOT kick in when rebuilding the system
507      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
508      Also, loading the versiontool does not work when rebuilding the system
509      because CM is not properly initialized at that time.

515    Description:
516    
517    Implemented some CM magic to have
518        file src/compiler/TopLevel/main/version.sml
519    generated automagically.
520    The version is taken from two files: config/version and config/release.
521    The first is expected to contain a two-part version number such as 110.49.
522    The second should contain a single number, but it may be missing.
523    
524    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
525    time the version tool is loaded (which is the first time you say CMB.make),
526    then the tool will increment the value stored in config/release every
527    time CMB.make is invoked.
528    
529    The binfile format is now insensitive to anything beyond the first
530    two components of a version number, so bumping the release does not render
531    binfiles incompatible.  Auto-bumping can be used to keep track of versions
532    during development without invalidating existing binfiles.
533    
534    In any case, every CMB.make updates the date information in version.sml.
535    (This is the date that is printed in the banner.)

548    Tag: blume-20040927-controls
549    Description:
550    
551    Added two pieces of functionality to the Controls interface:
552    
553    1.   val save'restore: 'a control -> unit -> unit
554    
555       grabs the current value of the control in stage 1 and restores it
556       in stage 2.
557    
558    2.   val set' : 'a control * 'a -> unit -> unit
559    
560       stores the given value into the control in stage 2 (i.e., delayed)
561       but does all error checking in stage 1.
562       (This is for string controls that need to do parse their argument --
563        something that might fail.  In some cases, notably in CM, one
564        already knows the intended argument but wants to delay the actual
565        assignment until a time when error recovery would be more difficult.)
566    
567    Changed the handling of controls in tool arguments to classes "sml" and
568    "lazysml":
569       - use Controls.save'restore as a more robust way of restoring the
570         old value (in particular: without having to re-parse the string)
571       - use controls to handle the "overload" keyword in the init group
572         (I believe this change actually fixes a long-standing obscure bug.)

577    Tag: blume-20040927-lazysml
578    Description:
579    
580    Added a new tool class called "lazysml" to CM's tool chest.  The only
581    difference to "sml" is that compilation is done with Control.lazysml
582    set to true.  A source of class "lazysml" is automatically recognized
583    by a file name suffix of ".lml".
584    
585    In addition to the above feature, the original class "sml" now also
586    supports a tool argument "lazy" which has the same effect.  As a
587    result, the following three lines are equivalent:
588    
589        foo.sml : lazysml
590        foo.sml : sml (lazy)
591        foo.sml (lazy)
592    
593    The setting goes into effect both during parsing and during
594    compilation.  The original setting is restored right after parsing and
595    after compilation, respectively.
596    
597    In addition to all the above, there is also a general mechanism to set
598    ANY of the "controls" that are available at the command line via
599    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
600    apply as well. (In fact, "lazy" is implemented as a special case of
601    the general mechanism.)
602    
603    The .cm file syntax uses a new keyword tool argument called "with".
604    There are several ways of indicating the desired settings:
605    
606        foo.sml (with:parser.quotations=true)
607        foo.sml (with:(name:parser.quotations value:true))
608        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
609        foo.sml (with:(name1=value1 name2=value2 ...))
610        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
611    
612        etc.
613    
614    Another possible abbreviation is to leave out the =v or value:v part
615    if the name refers to a boolean control (in which case the value is
616    taken to be true).  Thus, one could get lazy sml also by saying:
617    
618        foo.sml (with:parser.lazy-keyword=true)
619        foo.sml (with:parser.lazy-keyword)
620        foo.sml (with:(name:parser.lazy-keyword value:true))
621        foo.sml (with:(name:parser.lazy-keyword))

919    
920    - use paramAlloc to report c-calls with too many arguments
921      (for PPC version where parameter area is pre-allocated)
922    - added ccall_maxargspace to machspec (to implement the above)
923    - made "make" commend in CM's "make" tool configurable
924    - added option (default: on) for passing the name of the SML/NJ's "bin"
925      directory to "make"; the call looks like this:
926    
927         make <options> SMLNJ_BINDIR=<dir> <target>
928    
929      This can be used by the Makefile to, e.g., pick the "right" version
930      of ml-nlffigen.
931    - minor code tweaks

937    Description:
938    
939    NLFFI under Mac OS X now working (sort of).  This is largely untested,
940    though.
941    
942    Note:  1. You have to make a new, clean build of the runtime system.
943           2. There are new BOOTFILES, you have to use them!
944              (Doing the bootstrap process yourself would be *very* painful!
945               If you absolutely have to do it, build the system under
946               a different architecture and then cross-compile.)
947    
948    Version bumped to 110.46.1 to account for runtime data format changes.

954    Description:
955    
956    Changed the implementation of structure Unix so that the same stream
957    is returned every time one of the {text,bin}{In,Out}streamOf functions
958    is invoked on the same proc.  This is not what the spec currently
959    says -- although IMO it arguably should.  (See discussion below.)

972    Tag: blume-20040617-timer-unix
973    Description:
974    
975    Changed the interface of structures Timer and Unix to match the most
976    recent Basis spec.
977    
978    In the case of Unix there still seems to be an open/weird issue:
979    
980       The {text,bin}{In,Out}streamOf functions are supposed to create
981       fresh streams whenever they are called -- as opposed to have them
982       return the same stream every time.  This design is supposed to
983       prevent space leaks caused by proc values hanging on to streams.
984    
985       The reap function, on the other hand, is supposed to close the
986       streams.  This cannot be done without having a handle on the
987       stream in proc after all...
988    
989    I took the liberty to implement the following stopgap solution:
990    
991      The proc value hangs on to the most recently created stream(s).
992      Reap closes those.  If either or both of the two streams hadn't
993      been created at all yet, then reap will close the corresponding
994      file descriptors directly.
995    
996    PS: I don't understand the original space leak argument anymore.  If
997    a proc hangs on to the imperative stream, then I/O operations on those
998    will advance the state of the cached stream and avoid the space leak.

1011    Tag: blume-20040525-group-owner
1012    Description:
1013    
1014    CM now ignores (but still accepts) the "owner" information in group
1015    descriptions.  The owner of a group is its next enclosing
1016    library. Each group must have a unique owner.  (There is a virtual
1017    "toplevel" library that owns groups which are not nested within a real
1018    library.)  Previously, each group had to explicitly declare its owner,
1019    and CM would check that such a declaration is correct.  The new scheme
1020    is to have CM check that for each group there is precisely one owning
1021    library.
1022    
1023    The advantage of the new scheme is that the programmer no longer needs
1024    to maintain the somewhat annoying owner information.  The downside is
1025    that CM cannot enforce the ownership rule across multiple runs of
1026    CM.make.  Fortunately, enclosing the same group in two different
1027    libraries A and B which are not part of the same program does not
1028    cause real problems.

1038    compiled correctly.)
1039    
1040    Also, included a minor addition to ml-build.bat analogous to what was
1041    done in blume-20040519-ml-build.

1047    Description:
1048    
1049    Arranged for ml-build to clean up after itself a little bit better.
1050    The script generates a temporary SML source file and compiles it using
1051    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
1052    gets rid of those at the end, so they don't accumulate under .cm.
1053    
1054    This required a minor change to install.sh because the name of the
1055    metadata directory (default: .cm) is actually configurable at
1056    installation time.

1071    Description:
1072    
1073    Added previously missing support for many socket-related functions
1074    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
1075    for the voluminous patch!
1076    
1077    (I have not tested this patch under win32 yet.)
1078    
1079    Here is David's e-mail:
1080    
1081    Hi,
1082    
1083    Attached to this email you find a diff against sml/nj 110.45
1084    that will enable socket support under Windows.
1085    
1086    To apply the patch (using unix or cygwin)
1087    1) gunzip runtime.diff.gz
1088    2) "cd" into "src/runtime" in the source tree of a fresh
1089       110.45 installation.
1090    3) patch -p 1 < [your/path/to]runtime.diff
1091    
1092    The code compiles fine but has NOT yet been extensively tested.
1093    I only ran a few tests for basic socket client functionality
1094    (which worked fine).  Especially the functions that use ioctl
1095    are not tested at all and might not work (see below).
1096    
1097    I implemented this since we want to move to a newer version of sml/nj
1098    but need socket support in order to use it.  This is the first time I
1099    even had a look at the sml/nj source,  so please review my changes
1100    before making this part of the distribution!  Here are a few issues
1101    that I think might be better for someone to solve who is more
1102    familiar with the sml/nj source (and socket programming):
1103    
1104    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
1105      exception since I could not figure out what the windows equivalent
1106      of these functions is
1107    
1108    - In sockets-osdep.h there are a some #include statements that are
1109      only used in a few files that include sockets-osdep.h
1110    
1111    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
1112      does not process its return value since I don't know how to
1113      report an error upwards.
1114    
1115    - It would probably be good to have a call to WSACleanup() when
1116      the library is unloaded (if there is such a possibility).
1117      Otherwise I think Windows will take care of this automatically
1118      when the process finishes.
1119    
1120    - I used ioctlsocket() as a replacement for ioctl() but I have
1121      no idea if that is actually the proper replacement on Windows.
1122    
1123    - All these issues are marked in the code by "FIXME" comments.
1124    
1125    We use sml/nj extensively in our products and are quite happy
1126    with it.  I hope this contribution will help you.
1127    
1128    Keep up the good work!
1129

1168    in the "targets" file, then the installer will pull in sources for
1169    everything.  (Notice that this refers to source code only.  Compiled
1170    code is still only installed for modules that were requested explicitly
1171    or which are required for other modules that were requested explicitly.)

1205    Description:
1206    
1207    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
1208    of SML/NJ.  The problem is that
1209    
1210       lib = dlopen(NULL, ...)
1211       f   = dlsym(lib, "malloc");
1212    
1213    does not work on Windows unless we explicitly export symbols
1214    such as 'malloc' during linking.  We fixed this by explicitly
1215    exporting the required symbols with the magic gcc incantation:
1216    
1217        -Wl,--export-all cygwin.def
1218    
1219    where cygwin.def is a file containing all the symbols that
1220    we wish to export.
1221    
1222    I suspect this is a Windows problem and we'll have to
1223    do the same (somehow with windows compilers) when
1224    we build the native win32 version with the system
1225    calls LoadLibrary/GetProcAddress.

1351    Description:
1352    
1353    I modified the read-eval-print loop so that the autoloader gets
1354    invoked whenever the prettyprinter tries to look up a symbol that
1355    is not currently defined in the toplevel environment but which
1356    appears in CM's autoload registry.  As a result, we see far fewer of
1357    those ?.Foo.Bar.xxx names in the prettyprinter's output.
1358    
1359    In addition to this I tried to clean up some pieces of the Basis
1360    implementation (e.g., Socket, Word8Array) in order to prevent other
1361    instances of these ?.Foo.Bar.xxx names from being printed.
1362    
1363    The mechanism that picks names for types still needs some work, though.
1364    (Right now it seems that if there is a type A.t which is defined to
1365    be B.u, but B is unavailable at toplevel, then A.t gets printed as
1366    "?.B.u" although the perhaps more sensible solution would be to use
1367    "A.t" in this case.  In other words, the prettyprinter should follow
1368    a chain of DEFtycs not farther than there are corresponding toplevel
1369    names in the current environment.)

1375    Description:
1376    
1377    Another installer tweak:  All the ML code for the installer is now
1378    compiled during CMB.make and put into a little library called
1379    $smlnj/installer.cm.  The installation then simply invokes
1380    
1381       sml -m $smlnj/installer.cm
1382    
1383    and everything happens automagically.
1384    
1385    Win32:  ML code senses value of environment variable SMLNJ_HOME.
1386    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
1387            and BINDIR.
1388    
1389    The new scheme guarantees that the ML code responsible for the installation
1390    is in sync with the APIs of the main system.  Also, the installer is
1391    somewhat faster because the installer script is precompiled.

1399    Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
1400    but excludes all non-blocking operations.  Defined SOCKET (in Basis)
1401    and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
1402    implementations of non-blocking operations from CML's Socket
1403    structure.

1409    Description:
1410    
1411    1. Fixed SOCKET API and implementation to match Basis spec.
1412       This required changing the internal representation of sockets to one
1413       that remembers (for each socket file descriptor) whether it is currently
1414       blocking or non-blocking.  This state is maintained lazily (i.e., a system
1415       call is made only if the state actually needs to change).
1416    
1417    2. OS-specific details of sockets were moved into separate files, thus
1418       making it possible to unify the bulk of the socket implementations
1419       between Unix and Win32.
1420    
1421    3. CML's socket API changed accordingly.
1422       (Note that we need to remove non-blocking functions from this API
1423       since they are redundant in the case of CML!)
1424    
1425    4. CML's socket implementation now makes use of non-blocking functions
1426       provided by Basis, thus removing all OS-dependent code from this part
1427       of CML.
1428    
1429    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

1475    
1476    2. Added Time.{from,to}Nanoseconds to Time.
1477    
1478    3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
1479       For example, fromLargeInt never needs to look at more than 3 "big
1480       digits" to get its 53 bits of precision.

1493    with code that generates these values from their corresponding

1542    Description:
1543    
1544    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
1545    Modified config/install.bat to take advantage of it.  Also modified
1546    config/install.sh (and called it config/new-install.sh) to take advantage
1547    of it on Unix systems.  (The SML code is (supposed to be) platform-
1548    independent.)
1549    
1550    The installer can now install everything under Win32
1551    as well as under *nix as long as it compiles.
1552    
1553    Other changes:
1554    
1555      - made CML compile again under Win32
1556      - made eXene compile under Win32 (by providing a fake structure UnixSock
1557        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
1558      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
1559        same as type int;  under Win32 it isn't
1560      - fixed some slice-related problems in the win32-specific parts of CML
1561      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
1562        (under Win32, the volume name is case-insensitive, and the
1563        OS.Path code compares volume names for equality)

1580    Description:
1581    
1582      1. Changed interface to vectors and arrays in Basis to match
1583         (draft) Basis spec.
1584      2. Added signatures and implementations of slices according to
1585         Basis spec.
1586      3. Edited source code throughout the system to make it compile again
1587         under 1. and 2.  (In some cases code had to be added to have it
1588         match the new signatures.)
1589      4. MLRISC should be backward-compatible: the copies of the originals
1590         of files that needed to change under 3. were retained, the .cm files
1591         check the compiler version number and use old versions when
1592         appropriate.
1593      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
1594         dirstream -> string option (in accordance with Basis spec).
1595      6. When generating code that counts lines, ml-lex used function
1596         CharVector.foldli, taking advantage of its old interface.
1597         This has been replaced with the corresponding code from
1598         CharVectorSlice.  (html-lex must be re-lexed!)
1599      7. BitArray in smlnj-lib/Util has been extended/modified to match the
1600         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
1601      8. Removed temporary additions (fromInternal, toInternal) from the
1602         (now obsolete) IntInf in smlnj-lib/Util.
1603      9. Cleaned up structure Byte.
1604     10. Added localOffset, scan, and fromString to Date (according to spec).
1605         Cleaned/corrected implementation of Date.
1606         (Still need to check for correctness; implement better canonicalizeDate.)
1607     11. Added "scan" to signature IEEE_REAL.
1608     12. Some improvements to IntInf [in particular: efficiency-hack for
1609         mod and rem when second operand is 2 (for parity checks).]
1610     13. Changed representation of type Time.time, using a single IntInf.int
1611         value counting microseconds.  This considerably simplified the
1612         implementation of structure Time.  We now support negative time
1613         values; scan and fromString handle signs.
1614     14. Functor PrimIO now takes two additional arguments (VectorSlice and
1615         ArraySlice).

1621    Description:
1622    
1623    This is a major update which comes with a version number bump
1624    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
1625    and an implementation of IntInf in the Basis.
1626    
1627    There are a fairly large number of related changes and updates throughout
1628    the system:
1629    
1630    Basis:
1631            - Implemented IntInf.
1632            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
1633            - Added some missing Real64 operations, most notably Real.toLargeInt.
1634            - Added FixedInt as a synonym for Int32.
1635    
1636    compiler:
1637            * Added support for a built-in intinf type.
1638              - literals
1639              - pattern matching
1640              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
1641              - overloading on literals and operations
1642    
1643            This required adding a primitive type intinf, some additional
1644            primops, and implementations for several non-trivial intinf
1645            operations in Core.  (The intinf type is completely abstract
1646            to the compiler; all operations get delegated back to the Core.)
1647    
1648            * Intinf equality is handled by polyequal.  However, the compiler
1649            does not print its usual warning in this case (since polyequal
1650            is the right thing to do there).
1651    
1652            * Improved the organization of structure InlineT.
1653    
1654            * A word about conversion primops:
1655            If conversions involving intinf do not cancel out during
1656            CPS contract, then the compiler must insert calls to Core functions.
1657            Since all core access must be resolved already during the FLINT
1658            translate phase, it would be too late a the time of CPS contract
1659            to add new Core calls.  For this reason, conversion primops
1660            for intinf carry two arguments:  1. the numeric argument that
1661            they are supposed to convert, and 2. the Core function that
1662            can help with this conversion if necessary.  If CPS contract
1663            eliminates a primop, then the associated Core function becomes
1664            dead and goes away.  Intinf conversion primops that do not get
1665            eliminated by CPS contract get rewritten into calls of their
1666            core functions by a separate, new phase.
1667    
1668    interactive system:
1669            - Control.Print.intinfDepth controls max length of intinf constants
1670            being printed. (Analogous to Control.Print.stringDepth.)
1671            - Cleanup in printutil and pputil: got rid of unused stuff and
1672            duplicates; replaced some of the code with code that makes better
1673            use of library functionality.
1674    
1675    CM:
1676            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
1677            are no longer silent.
1678    
1679    CKIT:
1680            Fixed mismatched uses of Int32 and LargeInt.  I always decided
1681            in favor of LargeInt -- which is now the same as IntInf.
1682            CKIT-knowledgable people should check whether this is what's
1683            intended and otherwise change things back to using Int32 or
1684            FixedInt.
1685    
1686    Throughout the code:
1687            Started using IntInf.int literals and built-in operations
1688            (e.g., comparison with 0) where this seems appropriate.

1709    
1710    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
1711    
1712        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
1713    
1714    This patch restores SML/NJ's ability to run under win32.  There are a
1715    number of changes, including fixes for several bugs that had gone
1716    unnoticed until now:
1717    
1718      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
1719        trying to run the win32 version from within cygwin.)
1720    
1721      - There are a number of simple .bat scripts that substitute for their
1722        corresponding Unix shell-scripts.  (See below.)
1723    
1724      - The internals of ml-build have been modified slightly.  The main
1725        difference is that instead of calling ".link-sml" (or link-sml.bat)
1726        using OS.Process.system, the ML process delegates this task back
1727        to the script.  Otherwise problems arise in mixed environments such
1728        as Cygwin where scripts look and work like Unix scripts, but
1729        where OS.Process.system cannot run them.
1730    
1731      - In CM, the srcpath pickler used native pathname syntax -- which
1732        is incorrect in the case of cross-compilation.  The new pickle format
1733        is independent of platform-specific naming conventions.
1734    
1735      - Path configuration files (such as lib/pathconfig) can now choose
1736        between native and standard syntax.  Placing a line of the form
1737    
1738            standard!
1739    
1740        into the file causes all subsequent paths to be interpreted using
1741        CM standard pathname syntax (= Unix conventions); a line
1742    
1743            native!
1744    
1745        switches back to native style.  This was needed so that
1746        path config files can be written portably, see src/system/pathconfig.
1747    
1748      - Runtime system:
1749    
1750          - win32-filesys.c:  get_file_time and set_file_time now
1751            access modification time, not creation time.
1752    
1753          - I/O code made aware of new array representation.
1754    
1755          - Bug fixes in X86.prim.masm.
1756    
1757       - src/system/makeml made aware of win32. (For use under cygwin
1758            and other Unix-environments for windows.)
1759    
1760       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
1761         which caused BinIO.inputAll to fail consistently.
1762    
1763    .bat scripts:
1764    
1765       Windows .bat scripts assume that SMLNJ_HOME is defined.
1766    
1767       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
1768         applications (sml, ml-yacc, ml-lex).
1769       - ml-build.bat: analogous to ml-build.
1770       - config\install.bat:  Analogous to config/install.sh.  This requires
1771         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
1772         (nmake etc. must be on the path, and vcvars32 must have been run.)
1773         Moreover, sources for ml-lex and ml-yacc need to exist under src,
1774         and the bootfile hierarchy must have been unpacked under
1775         sml.boot.x86-win32.
1776         The script is very primitive and does a poor job at error checking.
1777         It only installs the base system, ml-lex, and ml-yacc.  No other
1778         libraries are being installed (i.e., you get only those that
1779         are part of the compiler.)
1780       - link-sml.bat:  analogous to .link-sml, but not currently used
1781    
1782    Unrelated bug fixes:
1783    
1784      - ml-nlffigen now exports structures ST_* corresponding to incomplete
1785        types.
1786      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
1787        otherwise.)

1813    Two changes:

1815      1. Added a flag for controlling whether non-exhaustive bindings will
1816         be treated as errors (default is false).
1817      2. Cleaned up the *entire* source tree so that CMB.make goes through
1818         without a single non-exhaustive match- or bind warning.

1824    Description:
1825    
1826    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
1827    
1828       This mainly affects the quality of error messages.  However, some
1829       of the code is now more straightforward than before. (Treatment of
1830       the above four constructs in translate.sml is much simpler than
1831       the "macro-expansion" that was going on before.  Plus, the mach-
1832       compiler no longer gets invoked just to be able to compile an
1833       if-expression.)
1834    
1835    2. The ErrorMsg.Error exception is now caught and absorbed by the
1836       interactive loop.

1842    Description:
1843    
1844        Ported the runtime system to cygwin, which uses the unix
1845    x86-unix bin files.  Missing/buggy features:
1846    
1847       o getnetbyname, getnetbyaddr: these functions seem to be missing in
1848         the Cygwin library.
1849       o Ctrl-C handling may be flaky.
1850       o Windows system calls and Windows I/O are not supported.
1851    
1852       A new set of binfiles is located at:
1853    
1854         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
1855    
1856       This is only needed for bootstrapping the cygwin version of smlnj.
1857       Other x86 versions can use the existing binfiles.

1882    Description:
1883    
1884    Fixed a serious bug in the rewrite code for FP spilling/reloading that
1885    sent the RA into an infinite loop when floating point registers get
1886    spilled.  (Because of this bug, e.g., nucleic stopped compiling between
1887    110.37 and 110.38.)
1888    There was another set of potential problems related to the handling of
1889    MLRISC annotations (but those did not yet cause real problems, apparently).

1897    Added a call of SrcPath.sync at the beginning of Parse.parse (in CM).
1898    This fixes the problem of CM getting confused by files that suddenly
1899    change their identity (e.g., by getting unlinked and recreated by some
1900    text editor such as vi).  There might be a better/cheaper/cleaner way
1901    of doing this, but for now this will have to do.

1915    Description:
1916    
1917    In good old tradition, there has been a slight hiccup so that we have
1918    to patch 110.42 after the fact.   The old release tag has been replaced
1919    (see below).
1920    
1921    The change solves a problem with two competing approaches the
1922    configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
1923    each other's way.
1924    
1925    This change only affects the runtime system code and the installer script.
1926    (No new bootfiles.)

1950    Description:
1951    
1952    Sml now senses the SMLNJ_HOME environment variable.  If this is set,
1953    then the bin dir is assumed to be in $SMLNJ_HOME/bin and (unless
1954    CM_PATHCONFIG is also set), the path configuration file is assumed
1955    to be in $SMLNJ_HOME/lib/pathconfig.  This way one can easily move
1956    the entire tree to some other place and everything will "just work".
1957    
1958    (Companion commands such as ml-build and ml-makedepend also sense this
1959    variable.)

2012    
2013    Another small change is that ppDec tries to give more information
2014    than just "<sig>" in the case of functors.  However, this code is
2015    broken in some mysterious way if the functor's body's signature
2016    has not been declared by ascription but gets inferred from the
2017    implementation.  This needs fixing...
