20    
21    smlnj-lib:
22    
23      Added function HashString.hashString' for substrings.
24      Hand-inlined CharVector.foldl into HashString (for speed).
25      Modified implementation of structure Atom to avoid extracting
26      strings from substrings unless necessary.

40    Tag: blume-20041124-position
41    Description:
42    
43    The compiler can now be compiled in a mode that makes structure Position
44    equal to Int64.  The default, however, is unchanged (Position = Int31)
45    for the time being.
46    
47    To enable 64-bit positions, use the following procedure:
48    
49    1. Start sml
50    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
51    3. Type
52          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
53    4. Run CMB.make() as usual.
54    
55    This is barely tested.  The only test so far was a little SML program
56    counting the number of characters in an 8-gigabyte file by
57    reading it character-by-character.  That test was successful.
58    
59    In support of 64-bit positions, a number of new functions have been
60    added to the runtime system.

100    Tag: blume-20041113-versiontool
101    Description:
102    
103    - Stripped down the versiontool: It now only handles the version number.
104      The date string is generated at bootstrap time (during makeml).
105    
106    - In a previous commit, fixed a minor issue with how polyequal is being
107      translated.  In particular, the code now "looks through" abstractions.
108      This results in slightly fewer polyEqual warnings and hopefully slightly
109      more efficient code.  Important examples for where this matters are
110      the new int64 and word64 types.

124    Tag: blume-20041111-more64
125    Description:
126    
127    All the pieces of Word64 are now there, with the exception of the
128    conversions from and to LargeWord. (Eventually these need to be identities,
129    but for the time being they don't even make sense because LargeWord is
130    32-bit wide.)
131    
132    Also started to add similar support for Int64, but major pieces of that
133    are still missing.
134

138    Tag: blume-20041111-word64
139    Description:
140    
141    Structure Word64 is now (almost) complete, word literals and patterns
142    seem to work.  There are a few odd pieces missing.  In particular,
143    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
144    at the moment.
145    
146    Making Word64 official would mean that LargeWord becomes Word64.  But
147    this requires extreme care because most word-word conversions have to
148    go through LargeWord, so making a mistake means loss of efficiency or
149    worse.  Eventually there will be a solution similar to (but actually
150    simpler than) what I did with IntInf.

156    Description:

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

176    New working version (110.50).  NEW BOOTFILES!
177    
178                 =====================
179    
180    Also:
181    
182      - Changend config/srcarchiveurl from a file just
183        containing the URL string into a file containing
184        shell script code.  The code has access to the $VERSION variable.
185      - Made corresponding changes to config/install.sh and config/unpack.
186      - Default contents of config/srcarchiveurl uses $VERSION and
187        normally does not have to be edited to reflect a version change.
188    
189      (As a result, a version change can be done by just editing
190       config/version, the rest is now automatic.)

206    
207    This is the HISTORY entry for two earlier commits, both concerning
208    the x86 c-calls code in MLRISC:
209    
210      - added a missing LOAD in the code that deals with struct arguments
211      - made sure the caller does not add the wrong number of bytes to the
212        stack pointer after a call of a function returning a struct
213        (the callee already pops the implicit argument which points to
214         the space reserved for the result)

230    Tag: blume-20041020-standalone-backtrace
231    Description:
232    
233    Added a mechanism for getting back-trace information from standalone
234    programs.  Here is how it works:
235    
236       1. The part of the program from which you want to get backtrace
237          information (usually the whole program) should be wrapped with
238          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
239          main program could be modified from something like
240    
241             fun main (pgm, args) = ...
242    
243         to
244    
245            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
246    
247       2. To be able to access BackTrace.monitor, you have to add
248          library $smlnj-tdp/plugins.cm to the .cm file that contains your
249          main function.
250    
251       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
252          CM might have created in the past for your project).
253    
254       4. Build the system using this command line:
255    
256             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
257                      myprog.cm MyProg.main myprog
258    
259          instead of the usual
260    
261             ml-build myprog.cm MyProg.main myprog
262    
263    I changed a library name:
264    
265       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
266    
267    New libraries:
268    
269       $smlnj-tdp/back-trace.cm
270          -- when loaded causes the back-trace plugin to be installed
271       $smlnj-tdp/coverage.cm
272          -- when loaded causes the coverage plugin to be installed

287    Tag: blume-20041015-coverage
288    Description:
289    
290    * Test coverage tool added!
291    * Further reorganization of tracing-, debugging-, and profiling support:
292    
293        - moved original BTImp -- now called BackTrace -- into a separate
294          library called $/trace-debug-profile.cm
295        - eliminated all mentions of BTrace from SMLofNJ.Internals
296        - only the instrumentation mechanism is now left in the compiler proper
297        - BackTrace module is a plugin which is NOT plugged in by default
298        - Coverage module is another such plugin
299    
300    To get the benefits of any of these plugin modules, the code in
301    question must be compiled with tdp instrumentation turned on.  This
302    can be done by setting SMLofNJ.Internals.TDP.mode to true.
303    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
304    
305    Plugins are selected at link time.  (Pre-compiled instrumented code
306    can be re-loaded with different plugins in effect.)  When an
307    instrumented module is linked, whatever plugins are at that time
308    enabled will come into effect for that module.
309    
310    To enable the back-trace plugin, load library $/trace-debug-profile.cm
311    and invoke BackTrace.install() (e.g., from the interactive prompt).
312    To enable the coverage plugin, load the same library and invoke
313    Coverage.install().
314    
315    Back-traces are generated automatically on uncaught exceptions and
316    when the code in question explicitly invokes BackTrace.trigger().
317    
318    Coverage (and execution frequency-) information must be queried
319    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

325    Description:

327    Snapshot of a significant overhaul of how the trace/debug/profile support
328    is hooked into the system (specifically: Core and SMLofNJ.Internals).

334    Description:
335    
336    Some rationalization of names:
337    
338       structure BTrace -> structure TDPInstrument
339       etc.
340    
341    This is is preparation of using the original back-trace
342    instrumentation for other purposes.  "TDP" stands for
343    Trace/Debug/Profile.
344    
345    The control flag controlling whether instrumentation is on or off is now
346    registered under a different name, so instead of running sml as
347    
348     sml -Cinstrument.btrace-mode=true
349    
350    one has to say
351    
352     sml -Ctdp.instrument=true

359    
360    Made some minor modifications to elabcore.sml to have source regions

362    regions being reported in error- and debug messages.

367    Tag: blume-20041008-cmkw
368    Description:
369    
370    Fixed handling of keywords in .cm files: After seeing "is" the lexer
371    treats subsequent occurrences of "group", "library", "source", "is",
372    "*", and "-" as ordinary identifiers rather than keywords.
373    
374    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
375    is supposed to accept a tool argument called "source", but this did
376    not work because of the clash with the keyword.

410    Added hack to make slave mode work in the presence of the version
411    tool.  (Still, since the master does two passes over the code for

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

419    Description:
420    
421    * Moved the "version" magic into its own little library under
422      src/system/smlnj/internal.  This avoids expensive reconstruction of
423      a stable src/compiler/core.cm.
424    
425    * At the same time, structure CompilerVersion is now known as
426      structure SMLNJVersion.
427    
428    * Arranged for the version tool to NOT kick in when rebuilding the system
429      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
430      Also, loading the versiontool does not work when rebuilding the system
431      because CM is not properly initialized at that time.

436    Tag: blume-20040929-autoversion
437    Description:
438    
439    Implemented some CM magic to have
440        file src/compiler/TopLevel/main/version.sml
441    generated automagically.
442    The version is taken from two files: config/version and config/release.
443    The first is expected to contain a two-part version number such as 110.49.
444    The second should contain a single number, but it may be missing.
445    
446    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
447    time the version tool is loaded (which is the first time you say CMB.make),
448    then the tool will increment the value stored in config/release every
449    time CMB.make is invoked.
450    
451    The binfile format is now insensitive to anything beyond the first
452    two components of a version number, so bumping the release does not render
453    binfiles incompatible.  Auto-bumping can be used to keep track of versions
454    during development without invalidating existing binfiles.
455    
456    In any case, every CMB.make updates the date information in version.sml.
457    (This is the date that is printed in the banner.)

471    Description:
472    
473    Added two pieces of functionality to the Controls interface:
474    
475    1.   val save'restore: 'a control -> unit -> unit
476    
477       grabs the current value of the control in stage 1 and restores it
478       in stage 2.
479    
480    2.   val set' : 'a control * 'a -> unit -> unit
481    
482       stores the given value into the control in stage 2 (i.e., delayed)
483       but does all error checking in stage 1.
484       (This is for string controls that need to do parse their argument --
485        something that might fail.  In some cases, notably in CM, one
486        already knows the intended argument but wants to delay the actual
487        assignment until a time when error recovery would be more difficult.)
488    
489    Changed the handling of controls in tool arguments to classes "sml" and
490    "lazysml":
491       - use Controls.save'restore as a more robust way of restoring the
492         old value (in particular: without having to re-parse the string)
493       - use controls to handle the "overload" keyword in the init group
494         (I believe this change actually fixes a long-standing obscure bug.)

499    Tag: blume-20040927-lazysml
500    Description:
501    
502    Added a new tool class called "lazysml" to CM's tool chest.  The only
503    difference to "sml" is that compilation is done with Control.lazysml
504    set to true.  A source of class "lazysml" is automatically recognized
505    by a file name suffix of ".lml".
506    
507    In addition to the above feature, the original class "sml" now also
508    supports a tool argument "lazy" which has the same effect.  As a
509    result, the following three lines are equivalent:
510    
511        foo.sml : lazysml
512        foo.sml : sml (lazy)
513        foo.sml (lazy)
514    
515    The setting goes into effect both during parsing and during
516    compilation.  The original setting is restored right after parsing and
517    after compilation, respectively.
518    
519    In addition to all the above, there is also a general mechanism to set
520    ANY of the "controls" that are available at the command line via
521    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
522    apply as well. (In fact, "lazy" is implemented as a special case of
523    the general mechanism.)
524    
525    The .cm file syntax uses a new keyword tool argument called "with".
526    There are several ways of indicating the desired settings:
527    
528        foo.sml (with:parser.quotations=true)
529        foo.sml (with:(name:parser.quotations value:true))
530        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
531        foo.sml (with:(name1=value1 name2=value2 ...))
532        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
533    
534        etc.
535    
536    Another possible abbreviation is to leave out the =v or value:v part
537    if the name refers to a boolean control (in which case the value is
538    taken to be true).  Thus, one could get lazy sml also by saying:
539    
540        foo.sml (with:parser.lazy-keyword=true)
541        foo.sml (with:parser.lazy-keyword)
542        foo.sml (with:(name:parser.lazy-keyword value:true))
543        foo.sml (with:(name:parser.lazy-keyword))

895    Description:
896    
897    Changed the interface of structures Timer and Unix to match the most
898    recent Basis spec.
899    
900    In the case of Unix there still seems to be an open/weird issue:
901    
902       The {text,bin}{In,Out}streamOf functions are supposed to create
903       fresh streams whenever they are called -- as opposed to have them
904       return the same stream every time.  This design is supposed to
905       prevent space leaks caused by proc values hanging on to streams.
906    
907       The reap function, on the other hand, is supposed to close the
908       streams.  This cannot be done without having a handle on the
909       stream in proc after all...
910    
911    I took the liberty to implement the following stopgap solution:
912    
913      The proc value hangs on to the most recently created stream(s).
914      Reap closes those.  If either or both of the two streams hadn't

916      file descriptors directly.
917    
918    PS: I don't understand the original space leak argument anymore.  If
919    a proc hangs on to the imperative stream, then I/O operations on those
920    will advance the state of the cached stream and avoid the space leak.

934    Description:
935    
936    CM now ignores (but still accepts) the "owner" information in group
937    descriptions.  The owner of a group is its next enclosing
938    library. Each group must have a unique owner.  (There is a virtual
939    "toplevel" library that owns groups which are not nested within a real
940    library.)  Previously, each group had to explicitly declare its owner,
941    and CM would check that such a declaration is correct.  The new scheme
942    is to have CM check that for each group there is precisely one owning
943    library.
944    
945    The advantage of the new scheme is that the programmer no longer needs
946    to maintain the somewhat annoying owner information.  The downside is
947    that CM cannot enforce the ownership rule across multiple runs of
948    CM.make.  Fortunately, enclosing the same group in two different
949    libraries A and B which are not part of the same program does not
950    cause real problems.

963    done in blume-20040519-ml-build.

969    Description:
970    
971    Arranged for ml-build to clean up after itself a little bit better.
972    The script generates a temporary SML source file and compiles it using
973    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
974    gets rid of those at the end, so they don't accumulate under .cm.
975    
976    This required a minor change to install.sh because the name of the
977    metadata directory (default: .cm) is actually configurable at
978    installation time.

993    Description:
994    
995    Added previously missing support for many socket-related functions
996    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
997    for the voluminous patch!
998    
999    (I have not tested this patch under win32 yet.)
1000    
1001    Here is David's e-mail:
1002    
1003    Hi,
1004    
1005    Attached to this email you find a diff against sml/nj 110.45
1006    that will enable socket support under Windows.
1007    
1008    To apply the patch (using unix or cygwin)
1009    1) gunzip runtime.diff.gz
1010    2) "cd" into "src/runtime" in the source tree of a fresh
1011       110.45 installation.
1012    3) patch -p 1 < [your/path/to]runtime.diff
1013    
1014    The code compiles fine but has NOT yet been extensively tested.
1015    I only ran a few tests for basic socket client functionality
1016    (which worked fine).  Especially the functions that use ioctl
1017    are not tested at all and might not work (see below).
1018    
1019    I implemented this since we want to move to a newer version of sml/nj
1020    but need socket support in order to use it.  This is the first time I
1021    even had a look at the sml/nj source,  so please review my changes
1022    before making this part of the distribution!  Here are a few issues
1023    that I think might be better for someone to solve who is more
1024    familiar with the sml/nj source (and socket programming):
1025    
1026    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
1027      exception since I could not figure out what the windows equivalent
1028      of these functions is
1029    
1030    - In sockets-osdep.h there are a some #include statements that are
1031      only used in a few files that include sockets-osdep.h
1032    
1033    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
1034      does not process its return value since I don't know how to
1035      report an error upwards.
1036    
1037    - It would probably be good to have a call to WSACleanup() when
1038      the library is unloaded (if there is such a possibility).
1039      Otherwise I think Windows will take care of this automatically
1040      when the process finishes.
1041    
1042    - I used ioctlsocket() as a replacement for ioctl() but I have
1043      no idea if that is actually the proper replacement on Windows.
1044    
1045    - All these issues are marked in the code by "FIXME" comments.
1046    
1047    We use sml/nj extensively in our products and are quite happy
1048    with it.  I hope this contribution will help you.
1049    
1050    Keep up the good work!
1051

1090    in the "targets" file, then the installer will pull in sources for
1091    everything.  (Notice that this refers to source code only.  Compiled
1092    code is still only installed for modules that were requested explicitly
1093    or which are required for other modules that were requested explicitly.)

1127    Description:
1128    
1129    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
1130    of SML/NJ.  The problem is that
1131    
1132       lib = dlopen(NULL, ...)
1133       f   = dlsym(lib, "malloc");
1134    
1135    does not work on Windows unless we explicitly export symbols
1136    such as 'malloc' during linking.  We fixed this by explicitly
1137    exporting the required symbols with the magic gcc incantation:
1138    
1139        -Wl,--export-all cygwin.def
1140    
1141    where cygwin.def is a file containing all the symbols that
1142    we wish to export.
1143    
1144    I suspect this is a Windows problem and we'll have to
1145    do the same (somehow with windows compilers) when
1146    we build the native win32 version with the system
1147    calls LoadLibrary/GetProcAddress.

1273    Description:
1274    
1275    I modified the read-eval-print loop so that the autoloader gets
1276    invoked whenever the prettyprinter tries to look up a symbol that
1277    is not currently defined in the toplevel environment but which
1278    appears in CM's autoload registry.  As a result, we see far fewer of
1279    those ?.Foo.Bar.xxx names in the prettyprinter's output.
1280    
1281    In addition to this I tried to clean up some pieces of the Basis
1282    implementation (e.g., Socket, Word8Array) in order to prevent other
1283    instances of these ?.Foo.Bar.xxx names from being printed.
1284    
1285    The mechanism that picks names for types still needs some work, though.
1286    (Right now it seems that if there is a type A.t which is defined to
1287    be B.u, but B is unavailable at toplevel, then A.t gets printed as
1288    "?.B.u" although the perhaps more sensible solution would be to use
1289    "A.t" in this case.  In other words, the prettyprinter should follow
1290    a chain of DEFtycs not farther than there are corresponding toplevel
1291    names in the current environment.)

1297    Description:
1298    
1299    Another installer tweak:  All the ML code for the installer is now
1300    compiled during CMB.make and put into a little library called
1301    $smlnj/installer.cm.  The installation then simply invokes
1302    
1303       sml -m $smlnj/installer.cm
1304    
1305    and everything happens automagically.
1306    
1307    Win32:  ML code senses value of environment variable SMLNJ_HOME.
1308    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
1309            and BINDIR.
1310    
1311    The new scheme guarantees that the ML code responsible for the installation
1312    is in sync with the APIs of the main system.  Also, the installer is
1313    somewhat faster because the installer script is precompiled.

1330    Tag: blume-20030924-sockets
1331    Description:
1332    
1333    1. Fixed SOCKET API and implementation to match Basis spec.
1334       This required changing the internal representation of sockets to one
1335       that remembers (for each socket file descriptor) whether it is currently
1336       blocking or non-blocking.  This state is maintained lazily (i.e., a system
1337       call is made only if the state actually needs to change).
1338    
1339    2. OS-specific details of sockets were moved into separate files, thus
1340       making it possible to unify the bulk of the socket implementations
1341       between Unix and Win32.
1342    
1343    3. CML's socket API changed accordingly.
1344       (Note that we need to remove non-blocking functions from this API
1345       since they are redundant in the case of CML!)
1346    
1347    4. CML's socket implementation now makes use of non-blocking functions
1348       provided by Basis, thus removing all OS-dependent code from this part
1349       of CML.
1350    
1351    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

1397    
1398    2. Added Time.{from,to}Nanoseconds to Time.
1399    
1400    3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
1401       For example, fromLargeInt never needs to look at more than 3 "big

1464    Description:
1465    
1466    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
1467    Modified config/install.bat to take advantage of it.  Also modified
1468    config/install.sh (and called it config/new-install.sh) to take advantage
1469    of it on Unix systems.  (The SML code is (supposed to be) platform-
1470    independent.)
1471    
1472    The installer can now install everything under Win32
1473    as well as under *nix as long as it compiles.
1474    
1475    Other changes:
1476    
1477      - made CML compile again under Win32
1478      - made eXene compile under Win32 (by providing a fake structure UnixSock
1479        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
1480      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
1481        same as type int;  under Win32 it isn't
1482      - fixed some slice-related problems in the win32-specific parts of CML
1483      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
1484        (under Win32, the volume name is case-insensitive, and the
1485        OS.Path code compares volume names for equality)

1501    Tag: blume-20030905-slices-etc
1502    Description:
1503    
1504      1. Changed interface to vectors and arrays in Basis to match
1505         (draft) Basis spec.
1506      2. Added signatures and implementations of slices according to
1507         Basis spec.
1508      3. Edited source code throughout the system to make it compile again
1509         under 1. and 2.  (In some cases code had to be added to have it
1510         match the new signatures.)
1511      4. MLRISC should be backward-compatible: the copies of the originals
1512         of files that needed to change under 3. were retained, the .cm files
1513         check the compiler version number and use old versions when
1514         appropriate.
1515      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
1516         dirstream -> string option (in accordance with Basis spec).
1517      6. When generating code that counts lines, ml-lex used function
1518         CharVector.foldli, taking advantage of its old interface.
1519         This has been replaced with the corresponding code from
1520         CharVectorSlice.  (html-lex must be re-lexed!)
1521      7. BitArray in smlnj-lib/Util has been extended/modified to match the
1522         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
1523      8. Removed temporary additions (fromInternal, toInternal) from the
1524         (now obsolete) IntInf in smlnj-lib/Util.
1525      9. Cleaned up structure Byte.
1526     10. Added localOffset, scan, and fromString to Date (according to spec).
1527         Cleaned/corrected implementation of Date.
1528         (Still need to check for correctness; implement better canonicalizeDate.)
1529     11. Added "scan" to signature IEEE_REAL.
1530     12. Some improvements to IntInf [in particular: efficiency-hack for
1531         mod and rem when second operand is 2 (for parity checks).]
1532     13. Changed representation of type Time.time, using a single IntInf.int
1533         value counting microseconds.  This considerably simplified the
1534         implementation of structure Time.  We now support negative time
1535         values; scan and fromString handle signs.
1536     14. Functor PrimIO now takes two additional arguments (VectorSlice and
1537         ArraySlice).

1543    Description:
1544    
1545    This is a major update which comes with a version number bump
1546    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
1547    and an implementation of IntInf in the Basis.
1548    
1549    There are a fairly large number of related changes and updates throughout
1550    the system:
1551    
1552    Basis:
1553            - Implemented IntInf.
1554            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
1555            - Added some missing Real64 operations, most notably Real.toLargeInt.
1556            - Added FixedInt as a synonym for Int32.
1557    
1558    compiler:
1559            * Added support for a built-in intinf type.
1560              - literals
1561              - pattern matching
1562              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
1563              - overloading on literals and operations
1564    
1565            This required adding a primitive type intinf, some additional
1566            primops, and implementations for several non-trivial intinf
1567            operations in Core.  (The intinf type is completely abstract
1568            to the compiler; all operations get delegated back to the Core.)
1569    
1570            * Intinf equality is handled by polyequal.  However, the compiler
1571            does not print its usual warning in this case (since polyequal
1572            is the right thing to do there).
1573    
1574            * Improved the organization of structure InlineT.
1575    
1576            * A word about conversion primops:
1577            If conversions involving intinf do not cancel out during
1578            CPS contract, then the compiler must insert calls to Core functions.
1579            Since all core access must be resolved already during the FLINT
1580            translate phase, it would be too late a the time of CPS contract
1581            to add new Core calls.  For this reason, conversion primops
1582            for intinf carry two arguments:  1. the numeric argument that
1583            they are supposed to convert, and 2. the Core function that
1584            can help with this conversion if necessary.  If CPS contract
1585            eliminates a primop, then the associated Core function becomes
1586            dead and goes away.  Intinf conversion primops that do not get
1587            eliminated by CPS contract get rewritten into calls of their
1588            core functions by a separate, new phase.
1589    
1590    interactive system:
1591            - Control.Print.intinfDepth controls max length of intinf constants
1592            being printed. (Analogous to Control.Print.stringDepth.)
1593            - Cleanup in printutil and pputil: got rid of unused stuff and
1594            duplicates; replaced some of the code with code that makes better
1595            use of library functionality.
1596    
1597    CM:
1598            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
1599            are no longer silent.
1600    
1601    CKIT:
1602            Fixed mismatched uses of Int32 and LargeInt.  I always decided
1603            in favor of LargeInt -- which is now the same as IntInf.
1604            CKIT-knowledgable people should check whether this is what's
1605            intended and otherwise change things back to using Int32 or
1606            FixedInt.
1607    
1608    Throughout the code:
1609            Started using IntInf.int literals and built-in operations
1610            (e.g., comparison with 0) where this seems appropriate.

1631    
1632    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
1633    
1634        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
1635    
1636    This patch restores SML/NJ's ability to run under win32.  There are a
1637    number of changes, including fixes for several bugs that had gone
1638    unnoticed until now:
1639    
1640      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
1641        trying to run the win32 version from within cygwin.)
1642    
1643      - There are a number of simple .bat scripts that substitute for their
1644        corresponding Unix shell-scripts.  (See below.)
1645    
1646      - The internals of ml-build have been modified slightly.  The main
1647        difference is that instead of calling ".link-sml" (or link-sml.bat)
1648        using OS.Process.system, the ML process delegates this task back
1649        to the script.  Otherwise problems arise in mixed environments such
1650        as Cygwin where scripts look and work like Unix scripts, but
1651        where OS.Process.system cannot run them.
1652    
1653      - In CM, the srcpath pickler used native pathname syntax -- which
1654        is incorrect in the case of cross-compilation.  The new pickle format
1655        is independent of platform-specific naming conventions.
1656    
1657      - Path configuration files (such as lib/pathconfig) can now choose
1658        between native and standard syntax.  Placing a line of the form
1659    
1660            standard!
1661    
1662        into the file causes all subsequent paths to be interpreted using
1663        CM standard pathname syntax (= Unix conventions); a line
1664    
1665            native!
1666    
1667        switches back to native style.  This was needed so that
1668        path config files can be written portably, see src/system/pathconfig.
1669    
1670      - Runtime system:
1671    
1672          - win32-filesys.c:  get_file_time and set_file_time now
1673            access modification time, not creation time.
1674    
1675          - I/O code made aware of new array representation.
1676    
1677          - Bug fixes in X86.prim.masm.
1678    
1679       - src/system/makeml made aware of win32. (For use under cygwin
1680            and other Unix-environments for windows.)
1681    
1682       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
1683         which caused BinIO.inputAll to fail consistently.
1684    
1685    .bat scripts:
1686    
1687       Windows .bat scripts assume that SMLNJ_HOME is defined.
1688    
1689       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
1690         applications (sml, ml-yacc, ml-lex).
1691       - ml-build.bat: analogous to ml-build.
1692       - config\install.bat:  Analogous to config/install.sh.  This requires
1693         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
1694         (nmake etc. must be on the path, and vcvars32 must have been run.)
1695         Moreover, sources for ml-lex and ml-yacc need to exist under src,
1696         and the bootfile hierarchy must have been unpacked under
1697         sml.boot.x86-win32.
1698         The script is very primitive and does a poor job at error checking.
1699         It only installs the base system, ml-lex, and ml-yacc.  No other
1700         libraries are being installed (i.e., you get only those that
1701         are part of the compiler.)
1702       - link-sml.bat:  analogous to .link-sml, but not currently used
1703    
1704    Unrelated bug fixes:
1705    
1706      - ml-nlffigen now exports structures ST_* corresponding to incomplete
1707        types.
1708      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
1709        otherwise.)

1740         without a single non-exhaustive match- or bind warning.

1746    Description:
1747    
1748    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
1749    
1750       This mainly affects the quality of error messages.  However, some
1751       of the code is now more straightforward than before. (Treatment of
1752       the above four constructs in translate.sml is much simpler than
1753       the "macro-expansion" that was going on before.  Plus, the mach-
1754       compiler no longer gets invoked just to be able to compile an
1755       if-expression.)
1756    
1757    2. The ErrorMsg.Error exception is now caught and absorbed by the
1758       interactive loop.

1764    Description:
1765    
1766        Ported the runtime system to cygwin, which uses the unix
1767    x86-unix bin files.  Missing/buggy features:
1768    
1769       o getnetbyname, getnetbyaddr: these functions seem to be missing in
1770         the Cygwin library.
1771       o Ctrl-C handling may be flaky.
1772       o Windows system calls and Windows I/O are not supported.
1773    
1774       A new set of binfiles is located at:
1775    
1776         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
1777    
1778       This is only needed for bootstrapping the cygwin version of smlnj.
1779       Other x86 versions can use the existing binfiles.

1804    Description:
1805    
1806    Fixed a serious bug in the rewrite code for FP spilling/reloading that
1807    sent the RA into an infinite loop when floating point registers get
1808    spilled.  (Because of this bug, e.g., nucleic stopped compiling between
1809    110.37 and 110.38.)
1810    There was another set of potential problems related to the handling of
1811    MLRISC annotations (but those did not yet cause real problems, apparently).

1817    Description:
1818    
1819    Added a call of SrcPath.sync at the beginning of Parse.parse (in CM).
1820    This fixes the problem of CM getting confused by files that suddenly
1821    change their identity (e.g., by getting unlinked and recreated by some
1822    text editor such as vi).  There might be a better/cheaper/cleaner way
1823    of doing this, but for now this will have to do.

1837    Description:
1838    
1839    In good old tradition, there has been a slight hiccup so that we have
1840    to patch 110.42 after the fact.   The old release tag has been replaced
1841    (see below).
1842    
1843    The change solves a problem with two competing approaches the
1844    configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
1845    each other's way.
1846    
1847    This change only affects the runtime system code and the installer script.
1848    (No new bootfiles.)

1863    
1864    The mltree operator DIVS must be implemented with an overflow check on
1865    the PPC because the hardware indicates divide-by-zero using "overflow" as
1866    well.

1872    Description:
1873    
1874    Sml now senses the SMLNJ_HOME environment variable.  If this is set,
1875    then the bin dir is assumed to be in $SMLNJ_HOME/bin and (unless
1876    CM_PATHCONFIG is also set), the path configuration file is assumed
1877    to be in $SMLNJ_HOME/lib/pathconfig.  This way one can easily move
1878    the entire tree to some other place and everything will "just work".
1879    
1880    (Companion commands such as ml-build and ml-makedepend also sense this
1881    variable.)

1916    max always return their first argument.)

1930    Description:
1931    
1932    I back-ported my implementation of IEEEReal.fromString from the
1933    idlbasis-devel branch so that we can test it.
1934    
1935    Another small change is that ppDec tries to give more information
1936    than just "<sig>" in the case of functors.  However, this code is
1937    broken in some mysterious way if the functor's body's signature
1938    has not been declared by ascription but gets inferred from the
1939    implementation.  This needs fixing...
