37    Description:
38    
39    1. Changed definition of type ControlRegistry.registry_tree to
40       include control_info (i.e., the name of the controlling environment
41       variable).
42    
43    2. Added command-line flags -e and -E to print the names of environment
44       variables that can be used to control internal settings.
45       (This uses the new API mentioned in 1.)

59    Description:
60    
61    Put target "mlrisc" back into the default list.
62    (There is no harm in having it, and some users have expressed their
63    wish to have "mlrisc" included by default.)

88    
89       Added a patch to _arch-n-opsys to enable the Cygwin runtime.
90    The Cygwin runtime is turned on by setting the environment
91    variable SMLNJ_CYGWIN_RUNTIME to 1.

105    Description:
106    
107    Upon request by Johannes Joemann:
108    
109    - improved ML code of installer to fall back to coping when renaming
110      fails (i.e., when source and target are on different file systems);
111      the code compiles but has yet to be tested in anger
112    - removed mlrisc from list of default targets (config/targets)

160    Description:
161    
162    Bug fix from Carl Hauser:
163    
164    single_source_shortest_paths in dijkstra.sml was observed to get wrong
165    answers (by comparing to single_source_shortest_paths in bellman-ford.sml).
166    
167    The problem is that following the expression A.update(dist,s,Num.zero)
168    it is necessary to update the priority queue using Q.decreaseWeight(Q,s).

173    Tag: blume-20040806-cmdline
174    Description:
175    
176    Fiddled with handling of command-line options:
177    
178      * sml now quits after processing the command line
179        if -H, -S, -h<n>, or -s<n> appears as the last
180        command-line argument
181      * a new option -q terminates the session when encountered on
182        the command line; subsequent arguments will be ignored
183      * bug fixes: short (erroneous) arguments are no longer ignored
184        completely

190    Description:
191    
192      - Added minimal IBM assembly syntax support for PowerPC.
193    
194      - Cygwin: manually changed the file cygwin.def.  Some exported symbols have
195        been altered in the runtime.  We need an automatic way to keep the file
196        in sync.

220    Description:
221

239    Description:
240    
241    Gearing up towards 110.47...
242    
243    - various minor bugfixes to ml-nlffigen
244    - a beginning of a manual for nlffi
245    
246    - eliminated 'export name=value' in config/install.sh as this does
247      not work with certain versions of /bin/sh
248      (Thanks to David King at Motorola for catching this.)
249    
250    - several bugfixes provided or suggested by David Hansel at Reactive Systems:
251      - added a test for tm==NULL to gmtime.c and localtime.c
252      - applied patch for incorrect GetFileTime under win32
253      - toSeconds -> toMilliseconds in Win32/win32-process.sml

259    Description:
260    
261    - Fixed minor issue in ml-nlffigen: Now generate structure T_foo
262      for a typedef to an incomplete type, but leave out the "typ" member.
263      (This is just for consistency.)
264    - Started to produce what is supposed to become better (i.e., comprehensive)
265      documentation of what ml-nlffigen does and produces.

271    Description:
272    
273    Added C_UNION to c-calls/c-types.sml and updated the machinery
274    (ml-nlffigen, cproto.sml) that conveys C function interface
275    information to the code generator.
276    
277    However, the actual architecture-specific implementation of function
278    arguments and results that are C unions is still not implemented.

284    Description:
285    
286        Added these instructions to the PowerPC architecture:

288        STWU(X), STFDU, STFSU
289    
290        etc...
291    
292        Note: I haven't added their instruction encoding into the description.

298    Description:
299    
300       Added the two instructions LWARX and STWCX to the PowerPC
301    instruction set.
302    
303       A (untested) rewrite of loop-structure.sml.  The old version
304    is completely broken.

309    Tag: blume-20040713-nlffi
310    Description:
311    
312    - use paramAlloc to report c-calls with too many arguments
313      (for PPC version where parameter area is pre-allocated)
314    - added ccall_maxargspace to machspec (to implement the above)
315    - made "make" commend in CM's "make" tool configurable
316    - added option (default: on) for passing the name of the SML/NJ's "bin"
317      directory to "make"; the call looks like this:
318    
319         make <options> SMLNJ_BINDIR=<dir> <target>
320    
321      This can be used by the Makefile to, e.g., pick the "right" version
322      of ml-nlffigen.
323    - minor code tweaks

329    Description:
330    
331    NLFFI under Mac OS X now working (sort of).  This is largely untested,
332    though.
333    
334    Note:  1. You have to make a new, clean build of the runtime system.
335           2. There are new BOOTFILES, you have to use them!
336              (Doing the bootstrap process yourself would be *very* painful!
337               If you absolutely have to do it, build the system under
338               a different architecture and then cross-compile.)
339    
340    Version bumped to 110.46.1 to account for runtime data format changes.

345    Tag: blume-20040618-unix
346    Description:
347    
348    Changed the implementation of structure Unix so that the same stream
349    is returned every time one of the {text,bin}{In,Out}streamOf functions
350    is invoked on the same proc.  This is not what the spec currently
351    says -- although IMO it arguably should.  (See discussion below.)

364    Tag: blume-20040617-timer-unix
365    Description:
366    
367    Changed the interface of structures Timer and Unix to match the most
368    recent Basis spec.
369    
370    In the case of Unix there still seems to be an open/weird issue:
371    
372       The {text,bin}{In,Out}streamOf functions are supposed to create
373       fresh streams whenever they are called -- as opposed to have them
374       return the same stream every time.  This design is supposed to
375       prevent space leaks caused by proc values hanging on to streams.
376    
377       The reap function, on the other hand, is supposed to close the
378       streams.  This cannot be done without having a handle on the
379       stream in proc after all...
380    
381    I took the liberty to implement the following stopgap solution:
382    
383      The proc value hangs on to the most recently created stream(s).
384      Reap closes those.  If either or both of the two streams hadn't
385      been created at all yet, then reap will close the corresponding
386      file descriptors directly.
387    
388    PS: I don't understand the original space leak argument anymore.  If
389    a proc hangs on to the imperative stream, then I/O operations on those
390    will advance the state of the cached stream and avoid the space leak.

403    Tag: blume-20040525-group-owner
404    Description:
405    
406    CM now ignores (but still accepts) the "owner" information in group
407    descriptions.  The owner of a group is its next enclosing
408    library. Each group must have a unique owner.  (There is a virtual
409    "toplevel" library that owns groups which are not nested within a real
410    library.)  Previously, each group had to explicitly declare its owner,
411    and CM would check that such a declaration is correct.  The new scheme
412    is to have CM check that for each group there is precisely one owning
413    library.
414    
415    The advantage of the new scheme is that the programmer no longer needs
416    to maintain the somewhat annoying owner information.  The downside is
417    that CM cannot enforce the ownership rule across multiple runs of
418    CM.make.  Fortunately, enclosing the same group in two different
419    libraries A and B which are not part of the same program does not
420    cause real problems.

426    Description:
427    
428    Made the win32 version work again.  (Strangely, a misplaced comma had
429    slipped into win32-process.c which prevented the runtime from being
430    compiled correctly.)
431    
432    Also, included a minor addition to ml-build.bat analogous to what was
433    done in blume-20040519-ml-build.

439    Description:
440    
441    Arranged for ml-build to clean up after itself a little bit better.
442    The script generates a temporary SML source file and compiles it using
443    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
444    gets rid of those at the end, so they don't accumulate under .cm.
445    
446    This required a minor change to install.sh because the name of the
447    metadata directory (default: .cm) is actually configurable at
448    installation time.

463    Description:
464    
465    Added previously missing support for many socket-related functions
466    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
467    for the voluminous patch!
468    
469    (I have not tested this patch under win32 yet.)
470    
471    Here is David's e-mail:
472    
473    Hi,
474    
475    Attached to this email you find a diff against sml/nj 110.45
476    that will enable socket support under Windows.
477    
478    To apply the patch (using unix or cygwin)
479    1) gunzip runtime.diff.gz
480    2) "cd" into "src/runtime" in the source tree of a fresh
481       110.45 installation.
482    3) patch -p 1 < [your/path/to]runtime.diff
483    
484    The code compiles fine but has NOT yet been extensively tested.
485    I only ran a few tests for basic socket client functionality
486    (which worked fine).  Especially the functions that use ioctl
487    are not tested at all and might not work (see below).
488    
489    I implemented this since we want to move to a newer version of sml/nj
490    but need socket support in order to use it.  This is the first time I
491    even had a look at the sml/nj source,  so please review my changes
492    before making this part of the distribution!  Here are a few issues
493    that I think might be better for someone to solve who is more
494    familiar with the sml/nj source (and socket programming):
495    
496    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
497      exception since I could not figure out what the windows equivalent
498      of these functions is
499    
500    - In sockets-osdep.h there are a some #include statements that are
501      only used in a few files that include sockets-osdep.h
502    
503    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
504      does not process its return value since I don't know how to
505      report an error upwards.
506    
507    - It would probably be good to have a call to WSACleanup() when
508      the library is unloaded (if there is such a possibility).
509      Otherwise I think Windows will take care of this automatically
510      when the process finishes.
511    
512    - I used ioctlsocket() as a replacement for ioctl() but I have
513      no idea if that is actually the proper replacement on Windows.
514    
515    - All these issues are marked in the code by "FIXME" comments.
516    
517    We use sml/nj extensively in our products and are quite happy
518    with it.  I hope this contribution will help you.
519    
520    Keep up the good work!
521    
522    David

555    Description:
556    
557    The installer now honors the "src-smlnj" target again, although its meaning
558    has changed from "all sources required for the compiler" to "all sources
559    the installer knows about".  In other words, if you enable "src-smlnj"
560    in the "targets" file, then the installer will pull in sources for
561    everything.  (Notice that this refers to source code only.  Compiled
562    code is still only installed for modules that were requested explicitly
563    or which are required for other modules that were requested explicitly.)

597    Description:
598    
599    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
600    of SML/NJ.  The problem is that
601    
602       lib = dlopen(NULL, ...)
603       f   = dlsym(lib, "malloc");
604    
605    does not work on Windows unless we explicitly export symbols
606    such as 'malloc' during linking.  We fixed this by explicitly
607    exporting the required symbols with the magic gcc incantation:
608    
609        -Wl,--export-all cygwin.def
610    
611    where cygwin.def is a file containing all the symbols that
612    we wish to export.
613    
614    I suspect this is a Windows problem and we'll have to
615    do the same (somehow with windows compilers) when
616    we build the native win32 version with the system
617    calls LoadLibrary/GetProcAddress.

687    Eliminated the "dont_move_libraries" directive in config/targets.
688    (The mechanism was broken and could not be fixed easily.  Moreover,
689    there does not seem to be any reason not to move all libraries into
690    lib during installation.  I originally implemented this directive as a
691    backward-compatibility feature when I first introduced the new CM.
692    Now that things have been stable for a long time and going back to the
693    old CM is not an option, there is no reason to keep it around.)

742    Tag: blume-20030926-ppautoload
743    Description:
744    
745    I modified the read-eval-print loop so that the autoloader gets
746    invoked whenever the prettyprinter tries to look up a symbol that
747    is not currently defined in the toplevel environment but which
748    appears in CM's autoload registry.  As a result, we see far fewer of
749    those ?.Foo.Bar.xxx names in the prettyprinter's output.
750    
751    In addition to this I tried to clean up some pieces of the Basis
752    implementation (e.g., Socket, Word8Array) in order to prevent other
753    instances of these ?.Foo.Bar.xxx names from being printed.
754    
755    The mechanism that picks names for types still needs some work, though.
756    (Right now it seems that if there is a type A.t which is defined to
757    be B.u, but B is unavailable at toplevel, then A.t gets printed as
758    "?.B.u" although the perhaps more sensible solution would be to use
759    "A.t" in this case.  In other words, the prettyprinter should follow
760    a chain of DEFtycs not farther than there are corresponding toplevel
761    names in the current environment.)

767    Description:
768    
769    Another installer tweak:  All the ML code for the installer is now
770    compiled during CMB.make and put into a little library called
771    $smlnj/installer.cm.  The installation then simply invokes
772    
773       sml -m $smlnj/installer.cm
774    
775    and everything happens automagically.
776    
777    Win32:  ML code senses value of environment variable SMLNJ_HOME.
778    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
779            and BINDIR.
780    
781    The new scheme guarantees that the ML code responsible for the installation
782    is in sync with the APIs of the main system.  Also, the installer is
783    somewhat faster because the installer script is precompiled.

794    implementations of non-blocking operations from CML's Socket
795    structure.

801    Description:
802    
803    1. Fixed SOCKET API and implementation to match Basis spec.
804       This required changing the internal representation of sockets to one
805       that remembers (for each socket file descriptor) whether it is currently
806       blocking or non-blocking.  This state is maintained lazily (i.e., a system
807       call is made only if the state actually needs to change).
808    
809    2. OS-specific details of sockets were moved into separate files, thus
810       making it possible to unify the bulk of the socket implementations
811       between Unix and Win32.
812    
813    3. CML's socket API changed accordingly.
814       (Note that we need to remove non-blocking functions from this API
815       since they are redundant in the case of CML!)
816    
817    4. CML's socket implementation now makes use of non-blocking functions
818       provided by Basis, thus removing all OS-dependent code from this part
819       of CML.
820    
821    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

933    Tag: blume-20030909-installer
934    Description:
935    
936    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
937    Modified config/install.bat to take advantage of it.  Also modified
938    config/install.sh (and called it config/new-install.sh) to take advantage
939    of it on Unix systems.  (The SML code is (supposed to be) platform-
940    independent.)
941    
942    The installer can now install everything under Win32
943    as well as under *nix as long as it compiles.
944    
945    Other changes:
946    
947      - made CML compile again under Win32
948      - made eXene compile under Win32 (by providing a fake structure UnixSock
949        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
950      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
951        same as type int;  under Win32 it isn't
952      - fixed some slice-related problems in the win32-specific parts of CML
953      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
954        (under Win32, the volume name is case-insensitive, and the
955        OS.Path code compares volume names for equality)

963    Made Win32 version of OS.FileSys.fullPath return current directory
964    when given an empty string.  This is what the spec says, and incidentally,
965    CM depends on it.  (CM otherwise goes into an infinite loop in certain
966    cases when presented with the name of a non-existing .cm file.)

971    Tag: blume-20030905-slices-etc
972    Description:
973    
974      1. Changed interface to vectors and arrays in Basis to match
975         (draft) Basis spec.
976      2. Added signatures and implementations of slices according to
977         Basis spec.
978      3. Edited source code throughout the system to make it compile again
979         under 1. and 2.  (In some cases code had to be added to have it
980         match the new signatures.)
981      4. MLRISC should be backward-compatible: the copies of the originals
982         of files that needed to change under 3. were retained, the .cm files
983         check the compiler version number and use old versions when
984         appropriate.
985      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
986         dirstream -> string option (in accordance with Basis spec).
987      6. When generating code that counts lines, ml-lex used function
988         CharVector.foldli, taking advantage of its old interface.
989         This has been replaced with the corresponding code from
990         CharVectorSlice.  (html-lex must be re-lexed!)
991      7. BitArray in smlnj-lib/Util has been extended/modified to match the
992         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
993      8. Removed temporary additions (fromInternal, toInternal) from the
994         (now obsolete) IntInf in smlnj-lib/Util.
995      9. Cleaned up structure Byte.
996     10. Added localOffset, scan, and fromString to Date (according to spec).
997         Cleaned/corrected implementation of Date.
998         (Still need to check for correctness; implement better canonicalizeDate.)
999     11. Added "scan" to signature IEEE_REAL.
1000     12. Some improvements to IntInf [in particular: efficiency-hack for
1001         mod and rem when second operand is 2 (for parity checks).]
1002     13. Changed representation of type Time.time, using a single IntInf.int
1003         value counting microseconds.  This considerably simplified the
1004         implementation of structure Time.  We now support negative time
1005         values; scan and fromString handle signs.
1006     14. Functor PrimIO now takes two additional arguments (VectorSlice and
1007         ArraySlice).

1012    Tag: blume-20030828-intinf
1013    Description:
1014    
1015    This is a major update which comes with a version number bump
1016    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
1017    and an implementation of IntInf in the Basis.
1018    
1019    There are a fairly large number of related changes and updates throughout
1020    the system:
1021    
1022    Basis:
1023            - Implemented IntInf.
1024            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
1025            - Added some missing Real64 operations, most notably Real.toLargeInt.
1026            - Added FixedInt as a synonym for Int32.
1027    
1028    compiler:
1029            * Added support for a built-in intinf type.
1030              - literals
1031              - pattern matching
1032              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
1033              - overloading on literals and operations
1034    
1035            This required adding a primitive type intinf, some additional
1036            primops, and implementations for several non-trivial intinf
1037            operations in Core.  (The intinf type is completely abstract
1038            to the compiler; all operations get delegated back to the Core.)
1039    
1040            * Intinf equality is handled by polyequal.  However, the compiler
1041            does not print its usual warning in this case (since polyequal
1042            is the right thing to do there).
1043    
1044            * Improved the organization of structure InlineT.
1045    
1046            * A word about conversion primops:
1047            If conversions involving intinf do not cancel out during
1048            CPS contract, then the compiler must insert calls to Core functions.
1049            Since all core access must be resolved already during the FLINT
1050            translate phase, it would be too late a the time of CPS contract
1051            to add new Core calls.  For this reason, conversion primops
1052            for intinf carry two arguments:  1. the numeric argument that
1053            they are supposed to convert, and 2. the Core function that
1054            can help with this conversion if necessary.  If CPS contract
1055            eliminates a primop, then the associated Core function becomes
1056            dead and goes away.  Intinf conversion primops that do not get
1057            eliminated by CPS contract get rewritten into calls of their
1058            core functions by a separate, new phase.
1059    
1060    interactive system:
1061            - Control.Print.intinfDepth controls max length of intinf constants
1062            being printed. (Analogous to Control.Print.stringDepth.)
1063            - Cleanup in printutil and pputil: got rid of unused stuff and
1064            duplicates; replaced some of the code with code that makes better
1065            use of library functionality.
1066    
1067    CM:
1068            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
1069            are no longer silent.
1070    
1071    CKIT:
1072            Fixed mismatched uses of Int32 and LargeInt.  I always decided
1073            in favor of LargeInt -- which is now the same as IntInf.
1074            CKIT-knowledgable people should check whether this is what's
1075            intended and otherwise change things back to using Int32 or
1076            FixedInt.
1077    
1078    Throughout the code:
1079            Started using IntInf.int literals and built-in operations
1080            (e.g., comparison with 0) where this seems appropriate.

1100    Description:
1101    
1102    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
1103    
1104        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
1105    
1106    This patch restores SML/NJ's ability to run under win32.  There are a
1107    number of changes, including fixes for several bugs that had gone
1108    unnoticed until now:
1109    
1110      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
1111        trying to run the win32 version from within cygwin.)
1112    
1113      - There are a number of simple .bat scripts that substitute for their
1114        corresponding Unix shell-scripts.  (See below.)
1115    
1116      - The internals of ml-build have been modified slightly.  The main
1117        difference is that instead of calling ".link-sml" (or link-sml.bat)
1118        using OS.Process.system, the ML process delegates this task back
1119        to the script.  Otherwise problems arise in mixed environments such
1120        as Cygwin where scripts look and work like Unix scripts, but
1121        where OS.Process.system cannot run them.
1122    
1123      - In CM, the srcpath pickler used native pathname syntax -- which
1124        is incorrect in the case of cross-compilation.  The new pickle format
1125        is independent of platform-specific naming conventions.
1126    
1127      - Path configuration files (such as lib/pathconfig) can now choose
1128        between native and standard syntax.  Placing a line of the form
1129    
1130            standard!
1131    
1132        into the file causes all subsequent paths to be interpreted using
1133        CM standard pathname syntax (= Unix conventions); a line
1134    
1135            native!
1136    
1137        switches back to native style.  This was needed so that
1138        path config files can be written portably, see src/system/pathconfig.
1139    
1140      - Runtime system:
1141    
1142          - win32-filesys.c:  get_file_time and set_file_time now
1143            access modification time, not creation time.
1144    
1145          - I/O code made aware of new array representation.
1146    
1147          - Bug fixes in X86.prim.masm.
1148    
1149       - src/system/makeml made aware of win32. (For use under cygwin
1150            and other Unix-environments for windows.)
1151    
1152       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
1153         which caused BinIO.inputAll to fail consistently.
1154    
1155    .bat scripts:
1156    
1157       Windows .bat scripts assume that SMLNJ_HOME is defined.
1158    
1159       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
1160         applications (sml, ml-yacc, ml-lex).
1161       - ml-build.bat: analogous to ml-build.
1162       - config\install.bat:  Analogous to config/install.sh.  This requires
1163         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
1164         (nmake etc. must be on the path, and vcvars32 must have been run.)
1165         Moreover, sources for ml-lex and ml-yacc need to exist under src,
1166         and the bootfile hierarchy must have been unpacked under
1167         sml.boot.x86-win32.
1168         The script is very primitive and does a poor job at error checking.
1169         It only installs the base system, ml-lex, and ml-yacc.  No other
1170         libraries are being installed (i.e., you get only those that
1171         are part of the compiler.)
1172       - link-sml.bat:  analogous to .link-sml, but not currently used
1173    
1174    Unrelated bug fixes:
1175    
1176      - ml-nlffigen now exports structures ST_* corresponding to incomplete
1177        types.
1178      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
1179        otherwise.)

1208         be treated as errors (default is false).
1209      2. Cleaned up the *entire* source tree so that CMB.make goes through
1210         without a single non-exhaustive match- or bind warning.

1216    Description:
1217    
1218    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
1219    
1220       This mainly affects the quality of error messages.  However, some
1221       of the code is now more straightforward than before. (Treatment of
1222       the above four constructs in translate.sml is much simpler than
1223       the "macro-expansion" that was going on before.  Plus, the mach-
1224       compiler no longer gets invoked just to be able to compile an
1225       if-expression.)
1226    
1227    2. The ErrorMsg.Error exception is now caught and absorbed by the
1228       interactive loop.

1234    Description:
1235    
1236        Ported the runtime system to cygwin, which uses the unix
1237    x86-unix bin files.  Missing/buggy features:
1238    
1239       o getnetbyname, getnetbyaddr: these functions seem to be missing in
1240         the Cygwin library.
1241       o Ctrl-C handling may be flaky.
1242       o Windows system calls and Windows I/O are not supported.
1243    
1244       A new set of binfiles is located at:
1245    
1246         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
1247    
1248       This is only needed for bootstrapping the cygwin version of smlnj.
1249       Other x86 versions can use the existing binfiles.

1308    
1309    In good old tradition, there has been a slight hiccup so that we have
1310    to patch 110.42 after the fact.   The old release tag has been replaced
1311    (see below).
1312    
1313    The change solves a problem with two competing approaches the
1314    configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
1315    each other's way.
1316    
1317    This change only affects the runtime system code and the installer script.

1332    Description:
1333    
1334    The mltree operator DIVS must be implemented with an overflow check on
1335    the PPC because the hardware indicates divide-by-zero using "overflow" as
1336    well.

1342    Description:
1343    
1344    Sml now senses the SMLNJ_HOME environment variable.  If this is set,
1345    then the bin dir is assumed to be in $SMLNJ_HOME/bin and (unless
1346    CM_PATHCONFIG is also set), the path configuration file is assumed
1347    to be in $SMLNJ_HOME/lib/pathconfig.  This way one can easily move
1348    the entire tree to some other place and everything will "just work".
1349    
1350    (Companion commands such as ml-build and ml-makedepend also sense this
1351    variable.)

1373    Description:
1374    
1375    Exported structure BTImp from $smlnj/viscomp/debugprof.cm so that
1376    other clients can set up backtracing support.

1382    Description:
1383    
1384    Fixed a bug in translation of INLMAX (and INLMIN) for the floating-point
1385    case.  (The sense of the isNaN test was reversed -- which made min and
1386    max always return their first argument.)

1400    Description:
1401    
1402    I back-ported my implementation of IEEEReal.fromString from the
1403    idlbasis-devel branch so that we can test it.
1404    
1405    Another small change is that ppDec tries to give more information
1406    than just "<sig>" in the case of functors.  However, this code is
1407    broken in some mysterious way if the functor's body's signature
1408    has not been declared by ascription but gets inferred from the
1409    implementation.  This needs fixing...

1417    Resurrected SMLofNJ.Internals.BTrace.mode.  (It accidentally fell by
1418    the wayside when I switched over to using Controls everywhere.)

1461    
1462    - John tweaked runtime to be silent on heap export (except when
1463      GC messages are on).
1464    - I added a few more things (cross-compiling versions of CMB) to
1465      config/preloads (as suggestions).

1471    Description:
1472    
1473    - Added ControlUtil structure to control-lib.cm.
1474    - Use it throughout.
1475    - Used Controls facility to define MLRISC controls (as opposed to
1476      registering MLRISC control ref cells with Controls after the fact)
1477    - Fixed messed-up controls priorities.
1478    
1479    * Removed again all the stuff from config/preloads that one wouldn't
1480      be able to preload at the time the initial heap image is built.
1481      (Many libraries, e.g., CML, do not exist yet at this time.  The
1482       only libraries that can be preloaded via config/preloads are those
1483       that come bundled with the bootfiles.)
