19    Description:
20    
21    Made some minor modifications to elabcore.sml to have source regions
22    be propagated more tightly -- resulting in better (i.e., smaller)
23    regions being reported in error- and debug messages.

28    Tag: blume-20041008-cmkw
29    Description:
30    
31    Fixed handling of keywords in .cm files: After seeing "is" the lexer
32    treats subsequent occurrences of "group", "library", "source", "is",
33    "*", and "-" as ordinary identifiers rather than keywords.
34    
35    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
36    is supposed to accept a tool argument called "source", but this did
37    not work because of the clash with the keyword.

43    Description:
44    
45    Assorted cleanup work:
46    
47      - got rid of intstrmap in favor of using the library's
48        hash table implementation
49      - threw out most of the pathnames stuff, as it was not used anyway
50      - simplified tokentable implementation
51      - fixed some minor spelling errors

57    Description:
58    
59    Cleaned up the absyn to reflect the invariant that HANDLE always
60    carries a FNexp as part of the type definition.  This eliminates some
61    superfluous sanity checks at runtime down the road.
62    
63    Some minor cleanup of the btrace code.

69    Description:
70    
71    Added hack to make slave mode work in the presence of the version
72    tool.  (Still, since the master does two passes over the code for
73    CMB.make, the release number gets bumped twice when slaves are
74    attached.  I don't know if this is worth fixing...)

79    Tag: blume-20040930-version
80    Description:
81    
82    * Moved the "version" magic into its own little library under
83    src/system/smlnj/internal.  This avoids expensive reconstruction
84    of a stable src/compiler/core.cm.
85    
86    * At the same time, structure CompilerVersion is now known as structure
87    SMLNJVersion.
88    
89    * Arranged for the version tool to NOT kick in when rebuilding the system
90      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
91      Also, loading the versiontool does not work when rebuilding the system
92      because CM is not properly initialized at that time.

97    Tag: blume-20040929-autoversion
98    Description:
99    
100    Implemented some CM magic to have
101        file src/compiler/TopLevel/main/version.sml
102    generated automagically.
103    The version is taken from two files: config/version and config/release.
104    The first is expected to contain a two-part version number such as 110.49.
105    The second should contain a single number, but it may be missing.
106    
107    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
108    time the version tool is loaded (which is the first time you say CMB.make),
109    then the tool will increment the value stored in config/release every
110    time CMB.make is invoked.
111    
112    The binfile format is now insensitive to anything beyond the first
113    two components of a version number, so bumping the release does not render
114    binfiles incompatible.  Auto-bumping can be used to keep track of versions
115    during development without invalidating existing binfiles.
116    
117    In any case, every CMB.make updates the date information in version.sml.
118    (This is the date that is printed in the banner.)

123    Tag: blume-20040928-controls
124    Description:
125    
126    Some cleanup of the controls code.
127    
128    ----------------------------------------------------------------------
129    Name: Matthias Blume (blume (at) tti - c (dot) org)
130    Date: 2004/09/27 22:08:00 CDT
131    Tag: blume-20040927-controls
132    Description:
133    
134    Added two pieces of functionality to the Controls interface:
135    
136    1.   val save'restore: 'a control -> unit -> unit
137    
138       grabs the current value of the control in stage 1 and restores it
139       in stage 2.
140    
141    2.   val set' : 'a control * 'a -> unit -> unit
142    
143       stores the given value into the control in stage 2 (i.e., delayed)
144       but does all error checking in stage 1.
145       (This is for string controls that need to do parse their argument --
146        something that might fail.  In some cases, notably in CM, one
147        already knows the intended argument but wants to delay the actual
148        assignment until a time when error recovery would be more difficult.)
149    
150    Changed the handling of controls in tool arguments to classes "sml" and
151    "lazysml":
152       - use Controls.save'restore as a more robust way of restoring the
153         old value (in particular: without having to re-parse the string)
154       - use controls to handle the "overload" keyword in the init group
155         (I believe this change actually fixes a long-standing obscure bug.)
156    
157    ----------------------------------------------------------------------
158    Name: Matthias Blume (blume (at) tti - c (dot) org)
159    Date: 2004/09/27 17:00:00 CDT
160    Tag: blume-20040927-lazysml
161    Description:
162    
163    Added a new tool class called "lazysml" to CM's tool chest.  The only
164    difference to "sml" is that compilation is done with Control.lazysml
165    set to true.  A source of class "lazysml" is automatically recognized
166    by a file name suffix of ".lml".
167    
168    In addition to the above feature, the original class "sml" now also
169    supports a tool argument "lazy" which has the same effect.  As a
170    result, the following three lines are equivalent:
171    
172        foo.sml : lazysml
173        foo.sml : sml (lazy)
174        foo.sml (lazy)
175    
176    The setting goes into effect both during parsing and during
177    compilation.  The original setting is restored right after parsing and
178    after compilation, respectively.
179    
180    In addition to all the above, there is also a general mechanism to set
181    ANY of the "controls" that are available at the command line via
182    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
183    apply as well. (In fact, "lazy" is implemented as a special case of
184    the general mechanism.)
185    
186    The .cm file syntax uses a new keyword tool argument called "with".
187    There are several ways of indicating the desired settings:
188    
189        foo.sml (with:parser.quotations=true)
190        foo.sml (with:(name:parser.quotations value:true))
191        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
192        foo.sml (with:(name1=value1 name2=value2 ...))
193        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
194    
195        etc.
196    
197    Another possible abbreviation is to leave out the =v or value:v part
198    if the name refers to a boolean control (in which case the value is
199    taken to be true).  Thus, one could get lazy sml also by saying:
200    
201        foo.sml (with:parser.lazy-keyword=true)
202        foo.sml (with:parser.lazy-keyword)
203        foo.sml (with:(name:parser.lazy-keyword value:true))
204        foo.sml (with:(name:parser.lazy-keyword))

228    Description:
229    
230    1. Changed definition of type ControlRegistry.registry_tree to
231       include control_info (i.e., the name of the controlling environment
232       variable).
233    
234    2. Added command-line flags -e and -E to print the names of environment
235       variables that can be used to control internal settings.
236       (This uses the new API mentioned in 1.)

353    Bug fix from Carl Hauser:
354    
355    single_source_shortest_paths in dijkstra.sml was observed to get wrong
356    answers (by comparing to single_source_shortest_paths in bellman-ford.sml).
357    
358    The problem is that following the expression A.update(dist,s,Num.zero)
359    it is necessary to update the priority queue using Q.decreaseWeight(Q,s).

464    Added C_UNION to c-calls/c-types.sml and updated the machinery
465    (ml-nlffigen, cproto.sml) that conveys C function interface
466    information to the code generator.
467    
468    However, the actual architecture-specific implementation of function
469    arguments and results that are C unions is still not implemented.

501    Description:
502    
503    - use paramAlloc to report c-calls with too many arguments
504      (for PPC version where parameter area is pre-allocated)
505    - added ccall_maxargspace to machspec (to implement the above)
506    - made "make" commend in CM's "make" tool configurable
507    - added option (default: on) for passing the name of the SML/NJ's "bin"
508      directory to "make"; the call looks like this:
509    
510         make <options> SMLNJ_BINDIR=<dir> <target>
511    
512      This can be used by the Makefile to, e.g., pick the "right" version
513      of ml-nlffigen.

522    NLFFI under Mac OS X now working (sort of).  This is largely untested,
523    though.
524    
525    Note:  1. You have to make a new, clean build of the runtime system.
526           2. There are new BOOTFILES, you have to use them!
527              (Doing the bootstrap process yourself would be *very* painful!
528               If you absolutely have to do it, build the system under
529               a different architecture and then cross-compile.)
530    
531    Version bumped to 110.46.1 to account for runtime data format changes.

556    Description:
557    
558    Changed the interface of structures Timer and Unix to match the most
559    recent Basis spec.
560    
561    In the case of Unix there still seems to be an open/weird issue:
562    
563       The {text,bin}{In,Out}streamOf functions are supposed to create
564       fresh streams whenever they are called -- as opposed to have them
565       return the same stream every time.  This design is supposed to
566       prevent space leaks caused by proc values hanging on to streams.
567    
568       The reap function, on the other hand, is supposed to close the
569       streams.  This cannot be done without having a handle on the
570       stream in proc after all...
571    
572    I took the liberty to implement the following stopgap solution:
573    
574      The proc value hangs on to the most recently created stream(s).
575      Reap closes those.  If either or both of the two streams hadn't
576      been created at all yet, then reap will close the corresponding
577      file descriptors directly.
578    
579    PS: I don't understand the original space leak argument anymore.  If
580    a proc hangs on to the imperative stream, then I/O operations on those
581    will advance the state of the cached stream and avoid the space leak.

594    Tag: blume-20040525-group-owner
595    Description:
596    
597    CM now ignores (but still accepts) the "owner" information in group
598    descriptions.  The owner of a group is its next enclosing
599    library. Each group must have a unique owner.  (There is a virtual
600    "toplevel" library that owns groups which are not nested within a real
601    library.)  Previously, each group had to explicitly declare its owner,
602    and CM would check that such a declaration is correct.  The new scheme
603    is to have CM check that for each group there is precisely one owning
604    library.
605    
606    The advantage of the new scheme is that the programmer no longer needs
607    to maintain the somewhat annoying owner information.  The downside is
608    that CM cannot enforce the ownership rule across multiple runs of
609    CM.make.  Fortunately, enclosing the same group in two different
610    libraries A and B which are not part of the same program does not
611    cause real problems.

623    Also, included a minor addition to ml-build.bat analogous to what was
624    done in blume-20040519-ml-build.

630    Description:
631    
632    Arranged for ml-build to clean up after itself a little bit better.
633    The script generates a temporary SML source file and compiles it using
634    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
635    gets rid of those at the end, so they don't accumulate under .cm.
636    
637    This required a minor change to install.sh because the name of the
638    metadata directory (default: .cm) is actually configurable at
639    installation time.

654    Description:
655    
656    Added previously missing support for many socket-related functions
657    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
658    for the voluminous patch!
659    
660    (I have not tested this patch under win32 yet.)
661    
662    Here is David's e-mail:
663    
664    Hi,
665    
666    Attached to this email you find a diff against sml/nj 110.45
667    that will enable socket support under Windows.
668    
669    To apply the patch (using unix or cygwin)
670    1) gunzip runtime.diff.gz
671    2) "cd" into "src/runtime" in the source tree of a fresh
672       110.45 installation.
673    3) patch -p 1 < [your/path/to]runtime.diff
674    
675    The code compiles fine but has NOT yet been extensively tested.
676    I only ran a few tests for basic socket client functionality
677    (which worked fine).  Especially the functions that use ioctl
678    are not tested at all and might not work (see below).
679    
680    I implemented this since we want to move to a newer version of sml/nj
681    but need socket support in order to use it.  This is the first time I
682    even had a look at the sml/nj source,  so please review my changes
683    before making this part of the distribution!  Here are a few issues
684    that I think might be better for someone to solve who is more
685    familiar with the sml/nj source (and socket programming):
686    
687    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
688      exception since I could not figure out what the windows equivalent
689      of these functions is
690    
691    - In sockets-osdep.h there are a some #include statements that are
692      only used in a few files that include sockets-osdep.h
693    
694    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
695      does not process its return value since I don't know how to
696      report an error upwards.
697    
698    - It would probably be good to have a call to WSACleanup() when
699      the library is unloaded (if there is such a possibility).
700      Otherwise I think Windows will take care of this automatically
701      when the process finishes.
702    
703    - I used ioctlsocket() as a replacement for ioctl() but I have
704      no idea if that is actually the proper replacement on Windows.
705    
706    - All these issues are marked in the code by "FIXME" comments.
707    
708    We use sml/nj extensively in our products and are quite happy
709    with it.  I hope this contribution will help you.
710    
711    Keep up the good work!
712    
713    David

753    code is still only installed for modules that were requested explicitly
754    or which are required for other modules that were requested explicitly.)

788    Description:
789    
790    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
791    of SML/NJ.  The problem is that
792    
793       lib = dlopen(NULL, ...)
794       f   = dlsym(lib, "malloc");
795    
796    does not work on Windows unless we explicitly export symbols
797    such as 'malloc' during linking.  We fixed this by explicitly
798    exporting the required symbols with the magic gcc incantation:
799    
800        -Wl,--export-all cygwin.def
801    
802    where cygwin.def is a file containing all the symbols that
803    we wish to export.
804    
805    I suspect this is a Windows problem and we'll have to
806    do the same (somehow with windows compilers) when
807    we build the native win32 version with the system
808    calls LoadLibrary/GetProcAddress.

933    Tag: blume-20030926-ppautoload
934    Description:
935    
936    I modified the read-eval-print loop so that the autoloader gets
937    invoked whenever the prettyprinter tries to look up a symbol that
938    is not currently defined in the toplevel environment but which
939    appears in CM's autoload registry.  As a result, we see far fewer of
940    those ?.Foo.Bar.xxx names in the prettyprinter's output.
941    
942    In addition to this I tried to clean up some pieces of the Basis
943    implementation (e.g., Socket, Word8Array) in order to prevent other
944    instances of these ?.Foo.Bar.xxx names from being printed.
945    
946    The mechanism that picks names for types still needs some work, though.
947    (Right now it seems that if there is a type A.t which is defined to
948    be B.u, but B is unavailable at toplevel, then A.t gets printed as
949    "?.B.u" although the perhaps more sensible solution would be to use
950    "A.t" in this case.  In other words, the prettyprinter should follow
951    a chain of DEFtycs not farther than there are corresponding toplevel
952    names in the current environment.)

958    Description:
959    
960    Another installer tweak:  All the ML code for the installer is now
961    compiled during CMB.make and put into a little library called
962    $smlnj/installer.cm.  The installation then simply invokes
963    
964       sml -m $smlnj/installer.cm
965    
966    and everything happens automagically.
967    
968    Win32:  ML code senses value of environment variable SMLNJ_HOME.
969    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
970            and BINDIR.
971    
972    The new scheme guarantees that the ML code responsible for the installation
973    is in sync with the APIs of the main system.  Also, the installer is
974    somewhat faster because the installer script is precompiled.

982    Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
983    but excludes all non-blocking operations.  Defined SOCKET (in Basis)

985    implementations of non-blocking operations from CML's Socket
986    structure.

992    Description:
993    
994    1. Fixed SOCKET API and implementation to match Basis spec.
995       This required changing the internal representation of sockets to one
996       that remembers (for each socket file descriptor) whether it is currently
997       blocking or non-blocking.  This state is maintained lazily (i.e., a system
998       call is made only if the state actually needs to change).
999    
1000    2. OS-specific details of sockets were moved into separate files, thus
1001       making it possible to unify the bulk of the socket implementations
1002       between Unix and Win32.
1003    
1004    3. CML's socket API changed accordingly.
1005       (Note that we need to remove non-blocking functions from this API
1006       since they are redundant in the case of CML!)
1007    
1008    4. CML's socket implementation now makes use of non-blocking functions
1009       provided by Basis, thus removing all OS-dependent code from this part
1010       of CML.
1011    
1012    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

1125    Description:
1126    
1127    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
1128    Modified config/install.bat to take advantage of it.  Also modified
1129    config/install.sh (and called it config/new-install.sh) to take advantage
1130    of it on Unix systems.  (The SML code is (supposed to be) platform-
1131    independent.)
1132    
1133    The installer can now install everything under Win32
1134    as well as under *nix as long as it compiles.
1135    
1136    Other changes:
1137    
1138      - made CML compile again under Win32
1139      - made eXene compile under Win32 (by providing a fake structure UnixSock
1140        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
1141      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
1142        same as type int;  under Win32 it isn't
1143      - fixed some slice-related problems in the win32-specific parts of CML
1144      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
1145        (under Win32, the volume name is case-insensitive, and the
1146        OS.Path code compares volume names for equality)

1163    Description:
1164    
1165      1. Changed interface to vectors and arrays in Basis to match
1166         (draft) Basis spec.
1167      2. Added signatures and implementations of slices according to
1168         Basis spec.
1169      3. Edited source code throughout the system to make it compile again
1170         under 1. and 2.  (In some cases code had to be added to have it
1171         match the new signatures.)
1172      4. MLRISC should be backward-compatible: the copies of the originals
1173         of files that needed to change under 3. were retained, the .cm files
1174         check the compiler version number and use old versions when
1175         appropriate.
1176      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
1177         dirstream -> string option (in accordance with Basis spec).
1178      6. When generating code that counts lines, ml-lex used function
1179         CharVector.foldli, taking advantage of its old interface.
1180         This has been replaced with the corresponding code from
1181         CharVectorSlice.  (html-lex must be re-lexed!)
1182      7. BitArray in smlnj-lib/Util has been extended/modified to match the
1183         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
1184      8. Removed temporary additions (fromInternal, toInternal) from the
1185         (now obsolete) IntInf in smlnj-lib/Util.
1186      9. Cleaned up structure Byte.
1187     10. Added localOffset, scan, and fromString to Date (according to spec).
1188         Cleaned/corrected implementation of Date.
1189         (Still need to check for correctness; implement better canonicalizeDate.)
1190     11. Added "scan" to signature IEEE_REAL.
1191     12. Some improvements to IntInf [in particular: efficiency-hack for
1192         mod and rem when second operand is 2 (for parity checks).]
1193     13. Changed representation of type Time.time, using a single IntInf.int
1194         value counting microseconds.  This considerably simplified the
1195         implementation of structure Time.  We now support negative time
1196         values; scan and fromString handle signs.
1197     14. Functor PrimIO now takes two additional arguments (VectorSlice and
1198         ArraySlice).

1204    Description:
1205    
1206    This is a major update which comes with a version number bump
1207    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
1208    and an implementation of IntInf in the Basis.
1209    
1210    There are a fairly large number of related changes and updates throughout
1211    the system:
1212    
1213    Basis:
1214            - Implemented IntInf.
1215            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
1216            - Added some missing Real64 operations, most notably Real.toLargeInt.
1217            - Added FixedInt as a synonym for Int32.
1218    
1219    compiler:
1220            * Added support for a built-in intinf type.
1221              - literals
1222              - pattern matching
1223              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
1224              - overloading on literals and operations
1225    
1226            This required adding a primitive type intinf, some additional
1227            primops, and implementations for several non-trivial intinf
1228            operations in Core.  (The intinf type is completely abstract
1229            to the compiler; all operations get delegated back to the Core.)
1230    
1231            * Intinf equality is handled by polyequal.  However, the compiler
1232            does not print its usual warning in this case (since polyequal
1233            is the right thing to do there).
1234    
1235            * Improved the organization of structure InlineT.
1236    
1237            * A word about conversion primops:
1238            If conversions involving intinf do not cancel out during
1239            CPS contract, then the compiler must insert calls to Core functions.
1240            Since all core access must be resolved already during the FLINT
1241            translate phase, it would be too late a the time of CPS contract
1242            to add new Core calls.  For this reason, conversion primops
1243            for intinf carry two arguments:  1. the numeric argument that
1244            they are supposed to convert, and 2. the Core function that
1245            can help with this conversion if necessary.  If CPS contract
1246            eliminates a primop, then the associated Core function becomes
1247            dead and goes away.  Intinf conversion primops that do not get
1248            eliminated by CPS contract get rewritten into calls of their
1249            core functions by a separate, new phase.
1250    
1251    interactive system:
1252            - Control.Print.intinfDepth controls max length of intinf constants
1253            being printed. (Analogous to Control.Print.stringDepth.)
1254            - Cleanup in printutil and pputil: got rid of unused stuff and
1255            duplicates; replaced some of the code with code that makes better
1256            use of library functionality.
1257    
1258    CM:
1259            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
1260            are no longer silent.
1261    
1262    CKIT:
1263            Fixed mismatched uses of Int32 and LargeInt.  I always decided
1264            in favor of LargeInt -- which is now the same as IntInf.
1265            CKIT-knowledgable people should check whether this is what's
1266            intended and otherwise change things back to using Int32 or
1267            FixedInt.
1268    
1269    Throughout the code:
1270            Started using IntInf.int literals and built-in operations
1271            (e.g., comparison with 0) where this seems appropriate.

1292    
1293    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
1294    
1295        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
1296    
1297    This patch restores SML/NJ's ability to run under win32.  There are a
1298    number of changes, including fixes for several bugs that had gone
1299    unnoticed until now:
1300    
1301      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
1302        trying to run the win32 version from within cygwin.)
1303    
1304      - There are a number of simple .bat scripts that substitute for their
1305        corresponding Unix shell-scripts.  (See below.)
1306    
1307      - The internals of ml-build have been modified slightly.  The main
1308        difference is that instead of calling ".link-sml" (or link-sml.bat)
1309        using OS.Process.system, the ML process delegates this task back
1310        to the script.  Otherwise problems arise in mixed environments such
1311        as Cygwin where scripts look and work like Unix scripts, but
1312        where OS.Process.system cannot run them.
1313    
1314      - In CM, the srcpath pickler used native pathname syntax -- which
1315        is incorrect in the case of cross-compilation.  The new pickle format
1316        is independent of platform-specific naming conventions.
1317    
1318      - Path configuration files (such as lib/pathconfig) can now choose
1319        between native and standard syntax.  Placing a line of the form
1320    
1321            standard!

1323        into the file causes all subsequent paths to be interpreted using
1324        CM standard pathname syntax (= Unix conventions); a line

1326            native!
1327    
1328        switches back to native style.  This was needed so that
1329        path config files can be written portably, see src/system/pathconfig.
1330    
1331      - Runtime system:
1332    
1333          - win32-filesys.c:  get_file_time and set_file_time now
1334            access modification time, not creation time.
1335    
1336          - I/O code made aware of new array representation.
1337    
1338          - Bug fixes in X86.prim.masm.
1339    
1340       - src/system/makeml made aware of win32. (For use under cygwin
1341            and other Unix-environments for windows.)
1342    
1343       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
1344         which caused BinIO.inputAll to fail consistently.
1345    
1346    .bat scripts:
1347    
1348       Windows .bat scripts assume that SMLNJ_HOME is defined.
1349    
1350       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
1351         applications (sml, ml-yacc, ml-lex).
1352       - ml-build.bat: analogous to ml-build.
1353       - config\install.bat:  Analogous to config/install.sh.  This requires
1354         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
1355         (nmake etc. must be on the path, and vcvars32 must have been run.)
1356         Moreover, sources for ml-lex and ml-yacc need to exist under src,
1357         and the bootfile hierarchy must have been unpacked under
1358         sml.boot.x86-win32.
1359         The script is very primitive and does a poor job at error checking.
1360         It only installs the base system, ml-lex, and ml-yacc.  No other
1361         libraries are being installed (i.e., you get only those that
1362         are part of the compiler.)
1363       - link-sml.bat:  analogous to .link-sml, but not currently used
1364    
1365    Unrelated bug fixes:
1366    
1367      - ml-nlffigen now exports structures ST_* corresponding to incomplete
1368        types.
1369      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
1370        otherwise.)

1394    Description:
1395    
1396    Two changes:
1397    
1398      1. Added a flag for controlling whether non-exhaustive bindings will
1399         be treated as errors (default is false).
1400      2. Cleaned up the *entire* source tree so that CMB.make goes through
1401         without a single non-exhaustive match- or bind warning.

1407    Description:
1408    
1409    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
1410    
1411       This mainly affects the quality of error messages.  However, some
1412       of the code is now more straightforward than before. (Treatment of
1413       the above four constructs in translate.sml is much simpler than
1414       the "macro-expansion" that was going on before.  Plus, the mach-
1415       compiler no longer gets invoked just to be able to compile an
1416       if-expression.)
1417    
1418    2. The ErrorMsg.Error exception is now caught and absorbed by the
1419       interactive loop.

1425    Description:
1426    
1427        Ported the runtime system to cygwin, which uses the unix
1428    x86-unix bin files.  Missing/buggy features:
1429    
1430       o getnetbyname, getnetbyaddr: these functions seem to be missing in
1431         the Cygwin library.
1432       o Ctrl-C handling may be flaky.
1433       o Windows system calls and Windows I/O are not supported.
1434    
1435       A new set of binfiles is located at:
1436    
1437         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
1438    
1439       This is only needed for bootstrapping the cygwin version of smlnj.
1440       Other x86 versions can use the existing binfiles.

1465    Description:
1466    
1467    Fixed a serious bug in the rewrite code for FP spilling/reloading that
1468    sent the RA into an infinite loop when floating point registers get
1469    spilled.  (Because of this bug, e.g., nucleic stopped compiling between
1470    110.37 and 110.38.)
1471    There was another set of potential problems related to the handling of
1472    MLRISC annotations (but those did not yet cause real problems, apparently).

1480    Added a call of SrcPath.sync at the beginning of Parse.parse (in CM).
1481    This fixes the problem of CM getting confused by files that suddenly
1482    change their identity (e.g., by getting unlinked and recreated by some
1483    text editor such as vi).  There might be a better/cheaper/cleaner way
1484    of doing this, but for now this will have to do.

1498    Description:
1499    
1500    In good old tradition, there has been a slight hiccup so that we have
1501    to patch 110.42 after the fact.   The old release tag has been replaced
1502    (see below).
1503    
1504    The change solves a problem with two competing approaches the
1505    configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
1506    each other's way.
1507    
1508    This change only affects the runtime system code and the installer script.
1509    (No new bootfiles.)

1527    well.
