26    Tag: blume-20041124-position
27    Description:
28    
29    The compiler can now be compiled in a mode that makes structure Position
30    equal to Int64.  The default, however, is unchanged (Position = Int31)
31    for the time being.
32    
33    To enable 64-bit positions, use the following procedure:
34    
35    1. Start sml
36    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
37    3. Type
38          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
39    4. Run CMB.make() as usual.
40    
41    This is barely tested.  The only test so far was a little SML program
42    counting the number of characters in an 8-gigabyte file by
43    reading it character-by-character.  That test was successful.
44    
45    In support of 64-bit positions, a number of new functions have been
46    added to the runtime system.

86    Tag: blume-20041113-versiontool
87    Description:
88    
89    - Stripped down the versiontool: It now only handles the version number.
90      The date string is generated at bootstrap time (during makeml).
91    
92    - In a previous commit, fixed a minor issue with how polyequal is being
93      translated.  In particular, the code now "looks through" abstractions.
94      This results in slightly fewer polyEqual warnings and hopefully slightly
95      more efficient code.  Important examples for where this matters are
96      the new int64 and word64 types.

111    Description:
112    
113    All the pieces of Word64 are now there, with the exception of the
114    conversions from and to LargeWord. (Eventually these need to be identities,
115    but for the time being they don't even make sense because LargeWord is
116    32-bit wide.)
117    
118    Also started to add similar support for Int64, but major pieces of that
119    are still missing.

124    Tag: blume-20041111-word64
125    Description:
126    
127    Structure Word64 is now (almost) complete, word literals and patterns
128    seem to work.  There are a few odd pieces missing.  In particular,
129    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
130    at the moment.
131    
132    Making Word64 official would mean that LargeWord becomes Word64.  But
133    this requires extreme care because most word-word conversions have to
134    go through LargeWord, so making a mistake means loss of efficiency or
135    worse.  Eventually there will be a solution similar to (but actually
136    simpler than) what I did with IntInf.

164                 =====================
165    
166    Also:
167    
168      - Changend config/srcarchiveurl from a file just
169        containing the URL string into a file containing
170        shell script code.  The code has access to the $VERSION variable.
171      - Made corresponding changes to config/install.sh and config/unpack.
172      - Default contents of config/srcarchiveurl uses $VERSION and
173        normally does not have to be edited to reflect a version change.
174    
175      (As a result, a version change can be done by just editing
176       config/version, the rest is now automatic.)

192    
193    This is the HISTORY entry for two earlier commits, both concerning
194    the x86 c-calls code in MLRISC:
195    
196      - added a missing LOAD in the code that deals with struct arguments
197      - made sure the caller does not add the wrong number of bytes to the
198        stack pointer after a call of a function returning a struct
199        (the callee already pops the implicit argument which points to
200         the space reserved for the result)

216    Tag: blume-20041020-standalone-backtrace
217    Description:
218    
219    Added a mechanism for getting back-trace information from standalone
220    programs.  Here is how it works:
221    
222       1. The part of the program from which you want to get backtrace
223          information (usually the whole program) should be wrapped with
224          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
225          main program could be modified from something like
226    
227             fun main (pgm, args) = ...
228    
229         to
230    
231            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
232    
233       2. To be able to access BackTrace.monitor, you have to add
234          library $smlnj-tdp/plugins.cm to the .cm file that contains your
235          main function.
236    
237       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
238          CM might have created in the past for your project).
239    
240       4. Build the system using this command line:
241    
242             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
243                      myprog.cm MyProg.main myprog
244    
245          instead of the usual
246    
247             ml-build myprog.cm MyProg.main myprog
248    
249    I changed a library name:
250    
251       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
252    
253    New libraries:
254    
255       $smlnj-tdp/back-trace.cm
256          -- when loaded causes the back-trace plugin to be installed
257       $smlnj-tdp/coverage.cm
258          -- when loaded causes the coverage plugin to be installed

273    Tag: blume-20041015-coverage
274    Description:
275    
276    * Test coverage tool added!
277    * Further reorganization of tracing-, debugging-, and profiling support:
278    
279        - moved original BTImp -- now called BackTrace -- into a separate
280          library called $/trace-debug-profile.cm
281        - eliminated all mentions of BTrace from SMLofNJ.Internals
282        - only the instrumentation mechanism is now left in the compiler proper
283        - BackTrace module is a plugin which is NOT plugged in by default
284        - Coverage module is another such plugin
285    
286    To get the benefits of any of these plugin modules, the code in
287    question must be compiled with tdp instrumentation turned on.  This
288    can be done by setting SMLofNJ.Internals.TDP.mode to true.
289    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
290    
291    Plugins are selected at link time.  (Pre-compiled instrumented code
292    can be re-loaded with different plugins in effect.)  When an
293    instrumented module is linked, whatever plugins are at that time
294    enabled will come into effect for that module.
295    
296    To enable the back-trace plugin, load library $/trace-debug-profile.cm
297    and invoke BackTrace.install() (e.g., from the interactive prompt).
298    To enable the coverage plugin, load the same library and invoke
299    Coverage.install().
300    
301    Back-traces are generated automatically on uncaught exceptions and
302    when the code in question explicitly invokes BackTrace.trigger().
303    
304    Coverage (and execution frequency-) information must be queried
305    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

311    Description:

320    Description:
321    
322    Some rationalization of names:
323    
324       structure BTrace -> structure TDPInstrument
325       etc.
326    
327    This is is preparation of using the original back-trace
328    instrumentation for other purposes.  "TDP" stands for
329    Trace/Debug/Profile.
330    
331    The control flag controlling whether instrumentation is on or off is now
332    registered under a different name, so instead of running sml as
333    
334     sml -Cinstrument.btrace-mode=true
335    
336    one has to say
337    
338     sml -Ctdp.instrument=true

345

353    Tag: blume-20041008-cmkw
354    Description:
355    
356    Fixed handling of keywords in .cm files: After seeing "is" the lexer
357    treats subsequent occurrences of "group", "library", "source", "is",
358    "*", and "-" as ordinary identifiers rather than keywords.
359    
360    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
361    is supposed to accept a tool argument called "source", but this did
362    not work because of the clash with the keyword.

395    
396    Added hack to make slave mode work in the presence of the version
397    tool.  (Still, since the master does two passes over the code for
398    CMB.make, the release number gets bumped twice when slaves are
399    attached.  I don't know if this is worth fixing...)

405    Description:
406    
407    * Moved the "version" magic into its own little library under
408      src/system/smlnj/internal.  This avoids expensive reconstruction of
409      a stable src/compiler/core.cm.
410    
411    * At the same time, structure CompilerVersion is now known as
412      structure SMLNJVersion.
413    
414    * Arranged for the version tool to NOT kick in when rebuilding the system
415      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
416      Also, loading the versiontool does not work when rebuilding the system
417      because CM is not properly initialized at that time.

422    Tag: blume-20040929-autoversion
423    Description:
424    
425    Implemented some CM magic to have
426        file src/compiler/TopLevel/main/version.sml
427    generated automagically.
428    The version is taken from two files: config/version and config/release.
429    The first is expected to contain a two-part version number such as 110.49.
430    The second should contain a single number, but it may be missing.
431    
432    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
433    time the version tool is loaded (which is the first time you say CMB.make),
434    then the tool will increment the value stored in config/release every
435    time CMB.make is invoked.
436    
437    The binfile format is now insensitive to anything beyond the first
438    two components of a version number, so bumping the release does not render
439    binfiles incompatible.  Auto-bumping can be used to keep track of versions
440    during development without invalidating existing binfiles.
441    
442    In any case, every CMB.make updates the date information in version.sml.
443    (This is the date that is printed in the banner.)

459    Added two pieces of functionality to the Controls interface:
460    
461    1.   val save'restore: 'a control -> unit -> unit

468       stores the given value into the control in stage 2 (i.e., delayed)
469       but does all error checking in stage 1.

471        something that might fail.  In some cases, notably in CM, one
472        already knows the intended argument but wants to delay the actual
473        assignment until a time when error recovery would be more difficult.)
474    
475    Changed the handling of controls in tool arguments to classes "sml" and
476    "lazysml":
477       - use Controls.save'restore as a more robust way of restoring the
478         old value (in particular: without having to re-parse the string)
479       - use controls to handle the "overload" keyword in the init group
480         (I believe this change actually fixes a long-standing obscure bug.)

485    Tag: blume-20040927-lazysml
486    Description:
487    
488    Added a new tool class called "lazysml" to CM's tool chest.  The only
489    difference to "sml" is that compilation is done with Control.lazysml
490    set to true.  A source of class "lazysml" is automatically recognized
491    by a file name suffix of ".lml".
492    
493    In addition to the above feature, the original class "sml" now also
494    supports a tool argument "lazy" which has the same effect.  As a
495    result, the following three lines are equivalent:
496    
497        foo.sml : lazysml
498        foo.sml : sml (lazy)
499        foo.sml (lazy)
500    
501    The setting goes into effect both during parsing and during
502    compilation.  The original setting is restored right after parsing and
503    after compilation, respectively.
504    
505    In addition to all the above, there is also a general mechanism to set
506    ANY of the "controls" that are available at the command line via
507    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
508    apply as well. (In fact, "lazy" is implemented as a special case of
509    the general mechanism.)
510    
511    The .cm file syntax uses a new keyword tool argument called "with".
512    There are several ways of indicating the desired settings:
513    
514        foo.sml (with:parser.quotations=true)
515        foo.sml (with:(name:parser.quotations value:true))
516        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
517        foo.sml (with:(name1=value1 name2=value2 ...))
518        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
519    
520        etc.
521    
522    Another possible abbreviation is to leave out the =v or value:v part
523    if the name refers to a boolean control (in which case the value is
524    taken to be true).  Thus, one could get lazy sml also by saying:
525    
526        foo.sml (with:parser.lazy-keyword=true)
527        foo.sml (with:parser.lazy-keyword)
528        foo.sml (with:(name:parser.lazy-keyword value:true))
529        foo.sml (with:(name:parser.lazy-keyword))

881    Description:
882    
883    Changed the interface of structures Timer and Unix to match the most
884    recent Basis spec.
885    
886    In the case of Unix there still seems to be an open/weird issue:
887    
888       The {text,bin}{In,Out}streamOf functions are supposed to create
889       fresh streams whenever they are called -- as opposed to have them
890       return the same stream every time.  This design is supposed to
891       prevent space leaks caused by proc values hanging on to streams.
892    
893       The reap function, on the other hand, is supposed to close the
894       streams.  This cannot be done without having a handle on the
895       stream in proc after all...
896    
897    I took the liberty to implement the following stopgap solution:
898    
899      The proc value hangs on to the most recently created stream(s).
900      Reap closes those.  If either or both of the two streams hadn't
901      been created at all yet, then reap will close the corresponding
902      file descriptors directly.
903    
904    PS: I don't understand the original space leak argument anymore.  If
905    a proc hangs on to the imperative stream, then I/O operations on those
906    will advance the state of the cached stream and avoid the space leak.

920    Description:
921    
922    CM now ignores (but still accepts) the "owner" information in group
923    descriptions.  The owner of a group is its next enclosing
924    library. Each group must have a unique owner.  (There is a virtual
925    "toplevel" library that owns groups which are not nested within a real
926    library.)  Previously, each group had to explicitly declare its owner,
927    and CM would check that such a declaration is correct.  The new scheme
928    is to have CM check that for each group there is precisely one owning
929    library.
930    
931    The advantage of the new scheme is that the programmer no longer needs
932    to maintain the somewhat annoying owner information.  The downside is
933    that CM cannot enforce the ownership rule across multiple runs of
934    CM.make.  Fortunately, enclosing the same group in two different
935    libraries A and B which are not part of the same program does not
936    cause real problems.

942    Description:
943    
944    Made the win32 version work again.  (Strangely, a misplaced comma had
945    slipped into win32-process.c which prevented the runtime from being
946    compiled correctly.)
947    
948    Also, included a minor addition to ml-build.bat analogous to what was
949    done in blume-20040519-ml-build.

955    Description:
956    
957    Arranged for ml-build to clean up after itself a little bit better.
958    The script generates a temporary SML source file and compiles it using
959    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
960    gets rid of those at the end, so they don't accumulate under .cm.
961    
962    This required a minor change to install.sh because the name of the
963    metadata directory (default: .cm) is actually configurable at
964    installation time.

979    Description:
980    
981    Added previously missing support for many socket-related functions
982    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
983    for the voluminous patch!
984    
985    (I have not tested this patch under win32 yet.)
986    
987    Here is David's e-mail:
988    
989    Hi,
990    
991    Attached to this email you find a diff against sml/nj 110.45
992    that will enable socket support under Windows.
993    
994    To apply the patch (using unix or cygwin)
995    1) gunzip runtime.diff.gz
996    2) "cd" into "src/runtime" in the source tree of a fresh
997       110.45 installation.
998    3) patch -p 1 < [your/path/to]runtime.diff
999    
1000    The code compiles fine but has NOT yet been extensively tested.
1001    I only ran a few tests for basic socket client functionality
1002    (which worked fine).  Especially the functions that use ioctl
1003    are not tested at all and might not work (see below).
1004    
1005    I implemented this since we want to move to a newer version of sml/nj
1006    but need socket support in order to use it.  This is the first time I
1007    even had a look at the sml/nj source,  so please review my changes
1008    before making this part of the distribution!  Here are a few issues
1009    that I think might be better for someone to solve who is more
1010    familiar with the sml/nj source (and socket programming):
1011    
1012    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
1013      exception since I could not figure out what the windows equivalent
1014      of these functions is
1015    
1016    - In sockets-osdep.h there are a some #include statements that are
1017      only used in a few files that include sockets-osdep.h
1018    
1019    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
1020      does not process its return value since I don't know how to
1021      report an error upwards.
1022    
1023    - It would probably be good to have a call to WSACleanup() when
1024      the library is unloaded (if there is such a possibility).
1025      Otherwise I think Windows will take care of this automatically
1026      when the process finishes.
1027    
1028    - I used ioctlsocket() as a replacement for ioctl() but I have
1029      no idea if that is actually the proper replacement on Windows.
1030    
1031    - All these issues are marked in the code by "FIXME" comments.
1032    
1033    We use sml/nj extensively in our products and are quite happy
1034    with it.  I hope this contribution will help you.
1035    
1036    Keep up the good work!
1037

1073    The installer now honors the "src-smlnj" target again, although its meaning
1074    has changed from "all sources required for the compiler" to "all sources

1076    in the "targets" file, then the installer will pull in sources for
1077    everything.  (Notice that this refers to source code only.  Compiled
1078    code is still only installed for modules that were requested explicitly
1079    or which are required for other modules that were requested explicitly.)

1113    Description:
1114    
1115    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
1116    of SML/NJ.  The problem is that
1117    
1118       lib = dlopen(NULL, ...)
1119       f   = dlsym(lib, "malloc");
1120    
1121    does not work on Windows unless we explicitly export symbols
1122    such as 'malloc' during linking.  We fixed this by explicitly
1123    exporting the required symbols with the magic gcc incantation:
1124    
1125        -Wl,--export-all cygwin.def
1126    
1127    where cygwin.def is a file containing all the symbols that
1128    we wish to export.
1129    
1130    I suspect this is a Windows problem and we'll have to
1131    do the same (somehow with windows compilers) when
1132    we build the native win32 version with the system
1133    calls LoadLibrary/GetProcAddress.

1208    Now that things have been stable for a long time and going back to the
1209    old CM is not an option, there is no reason to keep it around.)

1259    Description:
1260    
1261    I modified the read-eval-print loop so that the autoloader gets
1262    invoked whenever the prettyprinter tries to look up a symbol that
1263    is not currently defined in the toplevel environment but which
1264    appears in CM's autoload registry.  As a result, we see far fewer of
1265    those ?.Foo.Bar.xxx names in the prettyprinter's output.
1266    
1267    In addition to this I tried to clean up some pieces of the Basis
1268    implementation (e.g., Socket, Word8Array) in order to prevent other
1269    instances of these ?.Foo.Bar.xxx names from being printed.
1270    
1271    The mechanism that picks names for types still needs some work, though.
1272    (Right now it seems that if there is a type A.t which is defined to
1273    be B.u, but B is unavailable at toplevel, then A.t gets printed as
1274    "?.B.u" although the perhaps more sensible solution would be to use
1275    "A.t" in this case.  In other words, the prettyprinter should follow
1276    a chain of DEFtycs not farther than there are corresponding toplevel
1277    names in the current environment.)

1283    Description:
1284    
1285    Another installer tweak:  All the ML code for the installer is now
1286    compiled during CMB.make and put into a little library called
1287    $smlnj/installer.cm.  The installation then simply invokes
1288    
1289       sml -m $smlnj/installer.cm
1290    
1291    and everything happens automagically.
1292    
1293    Win32:  ML code senses value of environment variable SMLNJ_HOME.
1294    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
1295            and BINDIR.
1296    
1297    The new scheme guarantees that the ML code responsible for the installation
1298    is in sync with the APIs of the main system.  Also, the installer is
1299    somewhat faster because the installer script is precompiled.

1317    Description:
1318    
1319    1. Fixed SOCKET API and implementation to match Basis spec.
1320       This required changing the internal representation of sockets to one
1321       that remembers (for each socket file descriptor) whether it is currently
1322       blocking or non-blocking.  This state is maintained lazily (i.e., a system
1323       call is made only if the state actually needs to change).
1324    
1325    2. OS-specific details of sockets were moved into separate files, thus
1326       making it possible to unify the bulk of the socket implementations
1327       between Unix and Win32.
1328    
1329    3. CML's socket API changed accordingly.
1330       (Note that we need to remove non-blocking functions from this API
1331       since they are redundant in the case of CML!)
1332    
1333    4. CML's socket implementation now makes use of non-blocking functions
1334       provided by Basis, thus removing all OS-dependent code from this part
1335       of CML.
1336    
1337    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

1380    1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
1381       this seems to be controversial at the moment) and used those in
1382       Posix.ProcEnv.times.
1383    
1384    2. Added Time.{from,to}Nanoseconds to Time.
1385    
1386    3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
1387       For example, fromLargeInt never needs to look at more than 3 "big
1388       digits" to get its 53 bits of precision.

1450    Description:
1451    
1452    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
1453    Modified config/install.bat to take advantage of it.  Also modified
1454    config/install.sh (and called it config/new-install.sh) to take advantage
1455    of it on Unix systems.  (The SML code is (supposed to be) platform-
1456    independent.)
1457    
1458    The installer can now install everything under Win32
1459    as well as under *nix as long as it compiles.
1460    
1461    Other changes:
1462    
1463      - made CML compile again under Win32
1464      - made eXene compile under Win32 (by providing a fake structure UnixSock
1465        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
1466      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
1467        same as type int;  under Win32 it isn't
1468      - fixed some slice-related problems in the win32-specific parts of CML
1469      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
1470        (under Win32, the volume name is case-insensitive, and the
1471        OS.Path code compares volume names for equality)

1488    Description:
1489    
1490      1. Changed interface to vectors and arrays in Basis to match
1491         (draft) Basis spec.
1492      2. Added signatures and implementations of slices according to
1493         Basis spec.
1494      3. Edited source code throughout the system to make it compile again
1495         under 1. and 2.  (In some cases code had to be added to have it
1496         match the new signatures.)
1497      4. MLRISC should be backward-compatible: the copies of the originals
1498         of files that needed to change under 3. were retained, the .cm files
1499         check the compiler version number and use old versions when
1500         appropriate.
1501      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
1502         dirstream -> string option (in accordance with Basis spec).
1503      6. When generating code that counts lines, ml-lex used function
1504         CharVector.foldli, taking advantage of its old interface.
1505         This has been replaced with the corresponding code from
1506         CharVectorSlice.  (html-lex must be re-lexed!)
1507      7. BitArray in smlnj-lib/Util has been extended/modified to match the
1508         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
1509      8. Removed temporary additions (fromInternal, toInternal) from the
1510         (now obsolete) IntInf in smlnj-lib/Util.
1511      9. Cleaned up structure Byte.
1512     10. Added localOffset, scan, and fromString to Date (according to spec).
1513         Cleaned/corrected implementation of Date.
1514         (Still need to check for correctness; implement better canonicalizeDate.)
1515     11. Added "scan" to signature IEEE_REAL.
1516     12. Some improvements to IntInf [in particular: efficiency-hack for
1517         mod and rem when second operand is 2 (for parity checks).]
1518     13. Changed representation of type Time.time, using a single IntInf.int
1519         value counting microseconds.  This considerably simplified the
1520         implementation of structure Time.  We now support negative time
1521         values; scan and fromString handle signs.
1522     14. Functor PrimIO now takes two additional arguments (VectorSlice and
1523         ArraySlice).

1529    Description:
1530    
1531    This is a major update which comes with a version number bump
1532    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
1533    and an implementation of IntInf in the Basis.
1534    
1535    There are a fairly large number of related changes and updates throughout
1536    the system:
1537    
1538    Basis:
1539            - Implemented IntInf.
1540            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
1541            - Added some missing Real64 operations, most notably Real.toLargeInt.
1542            - Added FixedInt as a synonym for Int32.
1543    
1544    compiler:
1545            * Added support for a built-in intinf type.
1546              - literals
1547              - pattern matching
1548              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
1549              - overloading on literals and operations
1550    
1551            This required adding a primitive type intinf, some additional
1552            primops, and implementations for several non-trivial intinf
1553            operations in Core.  (The intinf type is completely abstract
1554            to the compiler; all operations get delegated back to the Core.)
1555    
1556            * Intinf equality is handled by polyequal.  However, the compiler
1557            does not print its usual warning in this case (since polyequal
1558            is the right thing to do there).
1559    
1560            * Improved the organization of structure InlineT.
1561    
1562            * A word about conversion primops:
1563            If conversions involving intinf do not cancel out during
1564            CPS contract, then the compiler must insert calls to Core functions.
1565            Since all core access must be resolved already during the FLINT
1566            translate phase, it would be too late a the time of CPS contract
1567            to add new Core calls.  For this reason, conversion primops
1568            for intinf carry two arguments:  1. the numeric argument that
1569            they are supposed to convert, and 2. the Core function that
1570            can help with this conversion if necessary.  If CPS contract
1571            eliminates a primop, then the associated Core function becomes
1572            dead and goes away.  Intinf conversion primops that do not get
1573            eliminated by CPS contract get rewritten into calls of their
1574            core functions by a separate, new phase.
1575    
1576    interactive system:
1577            - Control.Print.intinfDepth controls max length of intinf constants
1578            being printed. (Analogous to Control.Print.stringDepth.)
1579            - Cleanup in printutil and pputil: got rid of unused stuff and
1580            duplicates; replaced some of the code with code that makes better
1581            use of library functionality.
1582    
1583    CM:
1584            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
1585            are no longer silent.
1586    
1587    CKIT:
1588            Fixed mismatched uses of Int32 and LargeInt.  I always decided
1589            in favor of LargeInt -- which is now the same as IntInf.
1590            CKIT-knowledgable people should check whether this is what's
1591            intended and otherwise change things back to using Int32 or
1592            FixedInt.
1593    
1594    Throughout the code:
1595            Started using IntInf.int literals and built-in operations
1596            (e.g., comparison with 0) where this seems appropriate.

1616    Description:
1617    
1618    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
1619    
1620        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
1621    
1622    This patch restores SML/NJ's ability to run under win32.  There are a
1623    number of changes, including fixes for several bugs that had gone
1624    unnoticed until now:
1625    
1626      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
1627        trying to run the win32 version from within cygwin.)
1628    
1629      - There are a number of simple .bat scripts that substitute for their
1630        corresponding Unix shell-scripts.  (See below.)
1631    
1632      - The internals of ml-build have been modified slightly.  The main
1633        difference is that instead of calling ".link-sml" (or link-sml.bat)
1634        using OS.Process.system, the ML process delegates this task back
1635        to the script.  Otherwise problems arise in mixed environments such
1636        as Cygwin where scripts look and work like Unix scripts, but
1637        where OS.Process.system cannot run them.
1638    
1639      - In CM, the srcpath pickler used native pathname syntax -- which
1640        is incorrect in the case of cross-compilation.  The new pickle format
1641        is independent of platform-specific naming conventions.
1642    
1643      - Path configuration files (such as lib/pathconfig) can now choose
1644        between native and standard syntax.  Placing a line of the form
1645    
1646            standard!
1647    
1648        into the file causes all subsequent paths to be interpreted using
1649        CM standard pathname syntax (= Unix conventions); a line
1650    
1651            native!
1652    
1653        switches back to native style.  This was needed so that
1654        path config files can be written portably, see src/system/pathconfig.
1655    
1656      - Runtime system:
1657    
1658          - win32-filesys.c:  get_file_time and set_file_time now
1659            access modification time, not creation time.
1660    
1661          - I/O code made aware of new array representation.
1662    
1663          - Bug fixes in X86.prim.masm.
1664    
1665       - src/system/makeml made aware of win32. (For use under cygwin
1666            and other Unix-environments for windows.)
1667    
1668       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
1669         which caused BinIO.inputAll to fail consistently.
1670    
1671    .bat scripts:
1672    
1673       Windows .bat scripts assume that SMLNJ_HOME is defined.
1674    
1675       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
1676         applications (sml, ml-yacc, ml-lex).
1677       - ml-build.bat: analogous to ml-build.
1678       - config\install.bat:  Analogous to config/install.sh.  This requires
1679         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
1680         (nmake etc. must be on the path, and vcvars32 must have been run.)
1681         Moreover, sources for ml-lex and ml-yacc need to exist under src,
1682         and the bootfile hierarchy must have been unpacked under
1683         sml.boot.x86-win32.
1684         The script is very primitive and does a poor job at error checking.
1685         It only installs the base system, ml-lex, and ml-yacc.  No other
1686         libraries are being installed (i.e., you get only those that
1687         are part of the compiler.)
1688       - link-sml.bat:  analogous to .link-sml, but not currently used
1689    
1690    Unrelated bug fixes:
1691    
1692      - ml-nlffigen now exports structures ST_* corresponding to incomplete
1693        types.
1694      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
1695        otherwise.)

1725      2. Cleaned up the *entire* source tree so that CMB.make goes through
1726         without a single non-exhaustive match- or bind warning.

1733    
1734    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
1735    
1736       This mainly affects the quality of error messages.  However, some
1737       of the code is now more straightforward than before. (Treatment of
1738       the above four constructs in translate.sml is much simpler than
1739       the "macro-expansion" that was going on before.  Plus, the mach-
1740       compiler no longer gets invoked just to be able to compile an
1741       if-expression.)
1742    
1743    2. The ErrorMsg.Error exception is now caught and absorbed by the
1744       interactive loop.

1760       A new set of binfiles is located at:
1761    
1762         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
1763    
1764       This is only needed for bootstrapping the cygwin version of smlnj.
1765       Other x86 versions can use the existing binfiles.

1792    Fixed a serious bug in the rewrite code for FP spilling/reloading that
1793    sent the RA into an infinite loop when floating point registers get
1794    spilled.  (Because of this bug, e.g., nucleic stopped compiling between
1795    110.37 and 110.38.)
1796    There was another set of potential problems related to the handling of
1797    MLRISC annotations (but those did not yet cause real problems, apparently).

1807    change their identity (e.g., by getting unlinked and recreated by some
1808    text editor such as vi).  There might be a better/cheaper/cleaner way
1809    of doing this, but for now this will have to do.

1823    Description:
1824    
1825    In good old tradition, there has been a slight hiccup so that we have
1826    to patch 110.42 after the fact.   The old release tag has been replaced
1827    (see below).
1828    
1829    The change solves a problem with two competing approaches the
1830    configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
1831    each other's way.
1832    
1833    This change only affects the runtime system code and the installer script.
1834    (No new bootfiles.)

1859    
1860    Sml now senses the SMLNJ_HOME environment variable.  If this is set,
1861    then the bin dir is assumed to be in $SMLNJ_HOME/bin and (unless
1862    CM_PATHCONFIG is also set), the path configuration file is assumed
1863    to be in $SMLNJ_HOME/lib/pathconfig.  This way one can easily move
1864    the entire tree to some other place and everything will "just work".
1865    
1866    (Companion commands such as ml-build and ml-makedepend also sense this
1867    variable.)

1920    
1921    Another small change is that ppDec tries to give more information
1922    than just "<sig>" in the case of functors.  However, this code is
1923    broken in some mysterious way if the functor's body's signature
1924    has not been declared by ascription but gets inferred from the
1925    implementation.  This needs fixing...

2026    0. John Reppy made several modifications to the SML/NJ library.
2027       In particular, there is a shiny new controls-lib.cm.
2028    
2029    1. Pushed new controls interface through compiler so that everything
2030       compiles again.
2031    
2032    2. Added FormatComb and FORMAT_COMB to the CML version of the
2033       SML/NJ library (so that CML compiles again).
2034    
2035    3. Modified init scripts because XXX_DEFAULT environment variables
2036       are no longer with us.  (Boot-time initialization is now done
2037       using the same environment variables that are also used for
2038       startup-time initialization of controls.)

2044    Description:
2045    
2046            All pseudo-ops emitted before the first segment declaration
2047    such as TEXT, DATA, and BSS directives are assumed to be global
2048    declarations and are emitted first in the assembly file. This is
2049    useful in a number of situations where one has pseudo-ops that are not
2050    specific to any segment, and also works around the constraint that one
2051    cannot have client pseudo-ops in the TEXT segment.
2052    
2053            Because no segment is associated with these declarations it is
2054    an error to allocate any space or objects before the first segment
2055    directive and an exception will be raised. However, we cannot make
2056    this check for client pseudo-ops.
2057    
2058            These top level declarations are a field in the CFG graph_info.
2059    In theory you can continue to add to this field after the CFG has been
2060    built -- provided you know what you are doing;-)
