20    Description:
21    
22    New working version (110.58).  NEW BOOTFILES!
23    
24    I am freezing 110.59.  Changes other than the version-number increase:
25    
26      eXene:
27    
28         * committed changes to eXene from Alley Stoughton:
29             "fixed bugs in X authorization and resource handling, as well
30              as in the pile and viewport widgets"
31    
32      Runtime:
33        * fixed linking problem with NetBSD 3.x.
34    
35      Lexgen:
36        * lexgen tool handles non-ascii characters in 7-bit mode the same
37          way that ml-lex does
38    
39        * lexgen propagates exceptions the same way that ml-lex does
40    
41      CML:
42        * Fixed a bug in the SyncVar polling functions (iGetPoll,
43          mTakePoll, and mGetPoll) that could lead to livelock.

49    Description:
50    
51    Implemented ml-makedepend (i.e., CM.sources) in a better (more robust)
52    way.  This should hopefully fix the ml-makedepend problem permanently.

58    Description:
59    
60    Fixed long-standing bug with ml-makedepend where it would output a
61    spurious dependency to a non-existing file.  (This is a simple fix.
62    It might need further looking into.)

133    Description:
134    Changes to support building on x86-64 systems (using the 32-bit mode).

150    Tag: blume-20060214-intel-mac
151    Description:
152    
153    Hooked code for Darwin-specific Intel ABI into main compiler.
154    (This is a temporary solution which relies on the fact that the
155    compiler itself does not use NLFFI.  Eventually we need to divorce
156    intel mac from generic x86 unix code and make separate sets of binaries.)

169    Description:
170    Changes to support MacOS X on Intel hardware.  The C-calls support in
171    MLRISC must also be updated to support the MacOS X ABI.

184    Tag: blume-20051121-html-lib
185    Description:
186    
187    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
188    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
189    at the time when config/preloads is processed, the library has to
190    be referred to by another name.  In 110.57 this would be
191    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
192    to be valid as well.)
193    
194    Thanks to Todd Wilson (Fresno) for alerting me to this issue.

207    Tag: blume-20051119-fish
208    Description:
209    
210    Fixed a problem in config/install.sh where it tries to "fish" the
211    name of the CM metadata directory from the wrong place (because
212    the physical location of basis.cm has changed).  Also, corrected the
213    path anchor for $/html-lib.cm.  (Thanks to M. Fluet for pointing out
214    these problems.)

246    Date: 2005/11/15 21:35:00 CST
247    Tag: blume-22051115-versiontool
248    Description:
249    
250    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
251    file gets loaded as a tool -- by the equivalent of CM.make during the
252    run of CMB.make.  Thus, CMB's path configuration is meaningless for
253    it.  Instead, it has the status of "user code", so it should use
254    $/basis.cm to refer to the Basis library.  (At least that's true for
255    the purpose of bootstrapping the previous change.  In the future it
256    might make sense to have versiontool.cm refer to
257    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
258    compiler itself uses.)
259    
260    Also patched src/system/testml to have it activate those extra anchor
261    bindings in config/extrapathconfig.
262

266    Tag: blume-22051115-libraries
267    Description:
268    
269    This change affects the way the following libraries are tied into
270    the system:
271    
272       $/basis.cm
273       $/smlnj-lib.cm
274       $/pp-lib.cm
275       $/controls-lib.cm
276       $/html-lib.cm
277       $/ml-yacc-lib.cm
278    
279    These libraries are now internally (as seen from the source code
280    of the implementation itself) known by the following names:
281    
282       $smlnj/basis/basis.cm
283       $smlnj/smlnj-lib/smlnj-lib.cm
284       $smlnj/smlnj-lib/pp-lib.cm
285       $smlnj/smlnj-lib/controls-lib.cm
286       $smlnj/smlnj-lib/html-lib.cm
287       $smlnj/ml-yacc/ml-yacc-lib.cm
288    
289    This makes it possible to work with code that requires different
290    versions of these libraries, and which refers to these libraries using
291    their "default" names (i.e., the first set of names above).  In other
292    words, one can un-define or re-define those default names without
293    compromising the proper functioning of the compiler itself.
294    
295    A similar procedure had already been performed for several of the
296    MLRISC libraries that are linked into the compiler.  I did some
297    cleanup on this code.
298    
299    A new file in the config directory (named extrapathconfig) is
300    responsible for setting up path anchors that the compiler itself does
301    not need, but that are typically required by user code.

480    Tag: blume-20050516-redump-heap
481    Description:
482    
483    Added mechanism for re-creating a heap file for the interactive system
484    after configuration variables have been changed.
485    
486       CM.redump_heap : string -> unit
487    
488    This is much like SMLofNJ.exportML, but starting from the resulting
489    heap does not return to the caller of CM.redump_heap but
490    restarts the interactive system from scratch.  The original call of
491    CM.redump_heap does not return but ends the interactive session.
492    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
493    
494    Internally, redump_heap winds the dynamic execution context back to
495    the point where the original heap image was created and re-executes
496    the heap image generation code in the boot code.

612    Tag: blume-20050114-heap2exec
613    Description:
614    
615    Implemented new (but still experimental) heap2exec facility.  This is
616    tested under Mac OS X and should work under Linux (will test shortly).
617    It will probably also work on the Sparc (will test some time later).
618    
619      - removed old "HACKED_STANDALONE" hack from runtime
620    
621    To be able to test this, uncomment the request for "heap2asm" in
622    config/targets prior to installation.  (Notice that this is different
623    from "heap2exec" mentioned below.  Not a typo.)
624    
625    To perform an actual test, run the command
626    
627       $ bin/heap2exec heapfile execfile
628    
629    (You can put heap2exec on your shell's path.)
630    
631    For example, run
632    
633      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
634    
635    This will create a standalone executable called "mly" which you can
636    then invoke directly as a command.

781    Tag: blume-20041124-position
782    Description:
783    
784    The compiler can now be compiled in a mode that makes structure Position
785    equal to Int64.  The default, however, is unchanged (Position = Int31)
786    for the time being.
787    
788    To enable 64-bit positions, use the following procedure:
789    
790    1. Start sml
791    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
792    3. Type
793          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
794    4. Run CMB.make() as usual.
795    
796    This is barely tested.  The only test so far was a little SML program
797    counting the number of characters in an 8-gigabyte file by
798    reading it character-by-character.  That test was successful.
799    
800    In support of 64-bit positions, a number of new functions have been
801    added to the runtime system.

846    
847    - In a previous commit, fixed a minor issue with how polyequal is being
848      translated.  In particular, the code now "looks through" abstractions.
849      This results in slightly fewer polyEqual warnings and hopefully slightly
850      more efficient code.  Important examples for where this matters are
851      the new int64 and word64 types.

868    All the pieces of Word64 are now there, with the exception of the

870    but for the time being they don't even make sense because LargeWord is
871    32-bit wide.)
872    
873    Also started to add similar support for Int64, but major pieces of that
874    are still missing.

880    Description:
881    
882    Structure Word64 is now (almost) complete, word literals and patterns
883    seem to work.  There are a few odd pieces missing.  In particular,
884    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
885    at the moment.
886    
887    Making Word64 official would mean that LargeWord becomes Word64.  But
888    this requires extreme care because most word-word conversions have to
889    go through LargeWord, so making a mistake means loss of efficiency or
890    worse.  Eventually there will be a solution similar to (but actually
891    simpler than) what I did with IntInf.

928        normally does not have to be edited to reflect a version change.
929    
930      (As a result, a version change can be done by just editing
931       config/version, the rest is now automatic.)

951      - added a missing LOAD in the code that deals with struct arguments
952      - made sure the caller does not add the wrong number of bytes to the
953        stack pointer after a call of a function returning a struct
954        (the callee already pops the implicit argument which points to

971    Tag: blume-20041020-standalone-backtrace
972    Description:
973    
974    Added a mechanism for getting back-trace information from standalone
975    programs.  Here is how it works:
976    
977       1. The part of the program from which you want to get backtrace
978          information (usually the whole program) should be wrapped with
979          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
980          main program could be modified from something like
981    
982             fun main (pgm, args) = ...
983    
984         to
985    
986            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
987    
988       2. To be able to access BackTrace.monitor, you have to add
989          library $smlnj-tdp/plugins.cm to the .cm file that contains your
990          main function.
991    
992       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
993          CM might have created in the past for your project).
994    
995       4. Build the system using this command line:
996    
997             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
998                      myprog.cm MyProg.main myprog
999    
1000          instead of the usual
1001    
1002             ml-build myprog.cm MyProg.main myprog
1003    
1004    I changed a library name:
1005    
1006       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1007    
1008    New libraries:
1009    
1010       $smlnj-tdp/back-trace.cm
1011          -- when loaded causes the back-trace plugin to be installed
1012       $smlnj-tdp/coverage.cm
1013          -- when loaded causes the coverage plugin to be installed

1029    Description:
1030    
1031    * Test coverage tool added!
1032    * Further reorganization of tracing-, debugging-, and profiling support:
1033    
1034        - moved original BTImp -- now called BackTrace -- into a separate
1035          library called $/trace-debug-profile.cm
1036        - eliminated all mentions of BTrace from SMLofNJ.Internals
1037        - only the instrumentation mechanism is now left in the compiler proper
1038        - BackTrace module is a plugin which is NOT plugged in by default
1039        - Coverage module is another such plugin
1040    
1041    To get the benefits of any of these plugin modules, the code in
1042    question must be compiled with tdp instrumentation turned on.  This
1043    can be done by setting SMLofNJ.Internals.TDP.mode to true.
1044    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1045    
1046    Plugins are selected at link time.  (Pre-compiled instrumented code
1047    can be re-loaded with different plugins in effect.)  When an
1048    instrumented module is linked, whatever plugins are at that time
1049    enabled will come into effect for that module.
1050    
1051    To enable the back-trace plugin, load library $/trace-debug-profile.cm
1052    and invoke BackTrace.install() (e.g., from the interactive prompt).
1053    To enable the coverage plugin, load the same library and invoke
1054    Coverage.install().
1055    
1056    Back-traces are generated automatically on uncaught exceptions and
1057    when the code in question explicitly invokes BackTrace.trigger().
1058    
1059    Coverage (and execution frequency-) information must be queried
1060    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

1077    Some rationalization of names:

1082    This is is preparation of using the original back-trace
1083    instrumentation for other purposes.  "TDP" stands for
1084    Trace/Debug/Profile.
1085    
1086    The control flag controlling whether instrumentation is on or off is now
1087    registered under a different name, so instead of running sml as
1088    
1089     sml -Cinstrument.btrace-mode=true
1090    
1091    one has to say
1092

1109    Description:
1110    
1111    Fixed handling of keywords in .cm files: After seeing "is" the lexer
1112    treats subsequent occurrences of "group", "library", "source", "is",
1113    "*", and "-" as ordinary identifiers rather than keywords.
1114    
1115    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
1116    is supposed to accept a tool argument called "source", but this did
1117    not work because of the clash with the keyword.

1161    
1162    * Moved the "version" magic into its own little library under
1163      src/system/smlnj/internal.  This avoids expensive reconstruction of
1164      a stable src/compiler/core.cm.
1165    
1166    * At the same time, structure CompilerVersion is now known as
1167      structure SMLNJVersion.
1168    
1169    * Arranged for the version tool to NOT kick in when rebuilding the system
1170      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
1171      Also, loading the versiontool does not work when rebuilding the system
1172      because CM is not properly initialized at that time.

1177    Tag: blume-20040929-autoversion
1178    Description:
1179    
1180    Implemented some CM magic to have
1181        file src/compiler/TopLevel/main/version.sml
1182    generated automagically.
1183    The version is taken from two files: config/version and config/release.
1184    The first is expected to contain a two-part version number such as 110.49.
1185    The second should contain a single number, but it may be missing.
1186    
1187    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
1188    time the version tool is loaded (which is the first time you say CMB.make),
1189    then the tool will increment the value stored in config/release every
1190    time CMB.make is invoked.
1191    
1192    The binfile format is now insensitive to anything beyond the first
1193    two components of a version number, so bumping the release does not render
1194    binfiles incompatible.  Auto-bumping can be used to keep track of versions
1195    during development without invalidating existing binfiles.
1196    
1197    In any case, every CMB.make updates the date information in version.sml.
1198    (This is the date that is printed in the banner.)

1211    Tag: blume-20040927-controls
1212    Description:
1213    
1214    Added two pieces of functionality to the Controls interface:
1215    
1216    1.   val save'restore: 'a control -> unit -> unit
1217    
1218       grabs the current value of the control in stage 1 and restores it
1219       in stage 2.
1220    
1221    2.   val set' : 'a control * 'a -> unit -> unit
1222    
1223       stores the given value into the control in stage 2 (i.e., delayed)
1224       but does all error checking in stage 1.
1225       (This is for string controls that need to do parse their argument --
1226        something that might fail.  In some cases, notably in CM, one
1227        already knows the intended argument but wants to delay the actual
1228        assignment until a time when error recovery would be more difficult.)
1229    
1230    Changed the handling of controls in tool arguments to classes "sml" and
1231    "lazysml":
1232       - use Controls.save'restore as a more robust way of restoring the
1233         old value (in particular: without having to re-parse the string)
1234       - use controls to handle the "overload" keyword in the init group
1235         (I believe this change actually fixes a long-standing obscure bug.)

1240    Tag: blume-20040927-lazysml
1241    Description:
1242    
1243    Added a new tool class called "lazysml" to CM's tool chest.  The only
1244    difference to "sml" is that compilation is done with Control.lazysml
1245    set to true.  A source of class "lazysml" is automatically recognized
1246    by a file name suffix of ".lml".
1247    
1248    In addition to the above feature, the original class "sml" now also
1249    supports a tool argument "lazy" which has the same effect.  As a
1250    result, the following three lines are equivalent:
1251    
1252        foo.sml : lazysml
1253        foo.sml : sml (lazy)
1254        foo.sml (lazy)
1255    
1256    The setting goes into effect both during parsing and during
1257    compilation.  The original setting is restored right after parsing and
1258    after compilation, respectively.
1259    
1260    In addition to all the above, there is also a general mechanism to set
1261    ANY of the "controls" that are available at the command line via
1262    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
1263    apply as well. (In fact, "lazy" is implemented as a special case of
1264    the general mechanism.)
1265    
1266    The .cm file syntax uses a new keyword tool argument called "with".
1267    There are several ways of indicating the desired settings:
1268    
1269        foo.sml (with:parser.quotations=true)
1270        foo.sml (with:(name:parser.quotations value:true))
1271        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
1272        foo.sml (with:(name1=value1 name2=value2 ...))
1273        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
1274    
1275        etc.
1276    
1277    Another possible abbreviation is to leave out the =v or value:v part
1278    if the name refers to a boolean control (in which case the value is
1279    taken to be true).  Thus, one could get lazy sml also by saying:
1280    
1281        foo.sml (with:parser.lazy-keyword=true)
1282        foo.sml (with:parser.lazy-keyword)
1283        foo.sml (with:(name:parser.lazy-keyword value:true))
1284        foo.sml (with:(name:parser.lazy-keyword))

1381      fails (i.e., when source and target are on different file systems);
1382      the code compiles but has yet to be tested in anger

1636    Description:
1637    
1638    Changed the interface of structures Timer and Unix to match the most
1639    recent Basis spec.
1640    
1641    In the case of Unix there still seems to be an open/weird issue:
1642    
1643       The {text,bin}{In,Out}streamOf functions are supposed to create
1644       fresh streams whenever they are called -- as opposed to have them
1645       return the same stream every time.  This design is supposed to
1646       prevent space leaks caused by proc values hanging on to streams.
1647    
1648       The reap function, on the other hand, is supposed to close the
1649       streams.  This cannot be done without having a handle on the
1650       stream in proc after all...
1651    
1652    I took the liberty to implement the following stopgap solution:
1653    
1654      The proc value hangs on to the most recently created stream(s).
1655      Reap closes those.  If either or both of the two streams hadn't
1656      been created at all yet, then reap will close the corresponding
1657      file descriptors directly.
1658    
1659    PS: I don't understand the original space leak argument anymore.  If
1660    a proc hangs on to the imperative stream, then I/O operations on those
1661    will advance the state of the cached stream and avoid the space leak.

1675    Description:
1676    
1677    CM now ignores (but still accepts) the "owner" information in group
1678    descriptions.  The owner of a group is its next enclosing
1679    library. Each group must have a unique owner.  (There is a virtual
1680    "toplevel" library that owns groups which are not nested within a real
1681    library.)  Previously, each group had to explicitly declare its owner,
1682    and CM would check that such a declaration is correct.  The new scheme
1683    is to have CM check that for each group there is precisely one owning
1684    library.
1685    
1686    The advantage of the new scheme is that the programmer no longer needs
1687    to maintain the somewhat annoying owner information.  The downside is
1688    that CM cannot enforce the ownership rule across multiple runs of
1689    CM.make.  Fortunately, enclosing the same group in two different
1690    libraries A and B which are not part of the same program does not
1691    cause real problems.

1712    Arranged for ml-build to clean up after itself a little bit better.
1713    The script generates a temporary SML source file and compiles it using
1714    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
1715    gets rid of those at the end, so they don't accumulate under .cm.
1716    
1717    This required a minor change to install.sh because the name of the
1718    metadata directory (default: .cm) is actually configurable at
1719    installation time.

1734    Description:
1735    
1736    Added previously missing support for many socket-related functions
1737    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
1738    for the voluminous patch!
1739    
1740    (I have not tested this patch under win32 yet.)
1741    
1742    Here is David's e-mail:
1743    
1744    Hi,
1745    
1746    Attached to this email you find a diff against sml/nj 110.45
1747    that will enable socket support under Windows.
1748    
1749    To apply the patch (using unix or cygwin)
1750    1) gunzip runtime.diff.gz
1751    2) "cd" into "src/runtime" in the source tree of a fresh
1752       110.45 installation.
1753    3) patch -p 1 < [your/path/to]runtime.diff
1754    
1755    The code compiles fine but has NOT yet been extensively tested.
1756    I only ran a few tests for basic socket client functionality
1757    (which worked fine).  Especially the functions that use ioctl
1758    are not tested at all and might not work (see below).
1759    
1760    I implemented this since we want to move to a newer version of sml/nj
1761    but need socket support in order to use it.  This is the first time I
1762    even had a look at the sml/nj source,  so please review my changes
1763    before making this part of the distribution!  Here are a few issues
1764    that I think might be better for someone to solve who is more
1765    familiar with the sml/nj source (and socket programming):
1766    
1767    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
1768      exception since I could not figure out what the windows equivalent
1769      of these functions is
1770    
1771    - In sockets-osdep.h there are a some #include statements that are
1772      only used in a few files that include sockets-osdep.h
1773    
1774    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
1775      does not process its return value since I don't know how to
1776      report an error upwards.
1777    
1778    - It would probably be good to have a call to WSACleanup() when
1779      the library is unloaded (if there is such a possibility).
1780      Otherwise I think Windows will take care of this automatically
1781      when the process finishes.
1782

1784      no idea if that is actually the proper replacement on Windows.

1826    Description:
1827    
1828    The installer now honors the "src-smlnj" target again, although its meaning
1829    has changed from "all sources required for the compiler" to "all sources
1830    the installer knows about".  In other words, if you enable "src-smlnj"
1831    in the "targets" file, then the installer will pull in sources for
1832    everything.  (Notice that this refers to source code only.  Compiled
1833    code is still only installed for modules that were requested explicitly
1834    or which are required for other modules that were requested explicitly.)

1868    Description:
1869    
1870    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
1871    of SML/NJ.  The problem is that
1872    
1873       lib = dlopen(NULL, ...)
1874       f   = dlsym(lib, "malloc");
1875    
1876    does not work on Windows unless we explicitly export symbols
1877    such as 'malloc' during linking.  We fixed this by explicitly
1878    exporting the required symbols with the magic gcc incantation:
1879    
1880        -Wl,--export-all cygwin.def
1881    
1882    where cygwin.def is a file containing all the symbols that
1883    we wish to export.
1884    
1885    I suspect this is a Windows problem and we'll have to
1886    do the same (somehow with windows compilers) when
1887    we build the native win32 version with the system
1888    calls LoadLibrary/GetProcAddress.

1959    (The mechanism was broken and could not be fixed easily.  Moreover,
1960    there does not seem to be any reason not to move all libraries into
1961    lib during installation.  I originally implemented this directive as a
1962    backward-compatibility feature when I first introduced the new CM.
1963    Now that things have been stable for a long time and going back to the
1964    old CM is not an option, there is no reason to keep it around.)

2014    Description:
2015    
2016    I modified the read-eval-print loop so that the autoloader gets
2017    invoked whenever the prettyprinter tries to look up a symbol that
2018    is not currently defined in the toplevel environment but which
2019    appears in CM's autoload registry.  As a result, we see far fewer of
2020    those ?.Foo.Bar.xxx names in the prettyprinter's output.
2021    
2022    In addition to this I tried to clean up some pieces of the Basis
2023    implementation (e.g., Socket, Word8Array) in order to prevent other
2024    instances of these ?.Foo.Bar.xxx names from being printed.
2025    
2026    The mechanism that picks names for types still needs some work, though.
2027    (Right now it seems that if there is a type A.t which is defined to
2028    be B.u, but B is unavailable at toplevel, then A.t gets printed as
2029    "?.B.u" although the perhaps more sensible solution would be to use
2030    "A.t" in this case.  In other words, the prettyprinter should follow
2031    a chain of DEFtycs not farther than there are corresponding toplevel
2032    names in the current environment.)

2038    Description:
2039    
2040    Another installer tweak:  All the ML code for the installer is now
2041    compiled during CMB.make and put into a little library called
2042    $smlnj/installer.cm.  The installation then simply invokes
2043    
2044       sml -m $smlnj/installer.cm
2045    
2046    and everything happens automagically.
2047    
2048    Win32:  ML code senses value of environment variable SMLNJ_HOME.
2049    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
2050            and BINDIR.
2051    
2052    The new scheme guarantees that the ML code responsible for the installation
2053    is in sync with the APIs of the main system.  Also, the installer is
2054    somewhat faster because the installer script is precompiled.

2065    implementations of non-blocking operations from CML's Socket
2066    structure.

2071    Tag: blume-20030924-sockets
2072    Description:
2073    
2074    1. Fixed SOCKET API and implementation to match Basis spec.
2075       This required changing the internal representation of sockets to one
2076       that remembers (for each socket file descriptor) whether it is currently
2077       blocking or non-blocking.  This state is maintained lazily (i.e., a system
2078       call is made only if the state actually needs to change).
2079    
2080    2. OS-specific details of sockets were moved into separate files, thus
2081       making it possible to unify the bulk of the socket implementations
2082       between Unix and Win32.
2083    
2084    3. CML's socket API changed accordingly.
2085       (Note that we need to remove non-blocking functions from this API
2086       since they are redundant in the case of CML!)
2087    
2088    4. CML's socket implementation now makes use of non-blocking functions
2089       provided by Basis, thus removing all OS-dependent code from this part
2090       of CML.
2091    
2092    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

2213    The installer can now install everything under Win32
2214    as well as under *nix as long as it compiles.
2215    
2216    Other changes:
2217    
2218      - made CML compile again under Win32
2219      - made eXene compile under Win32 (by providing a fake structure UnixSock
2220        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
2221      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
2222        same as type int;  under Win32 it isn't
2223      - fixed some slice-related problems in the win32-specific parts of CML
2224      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
2225        (under Win32, the volume name is case-insensitive, and the
2226        OS.Path code compares volume names for equality)

2243    Description:
2244    
2245      1. Changed interface to vectors and arrays in Basis to match
2246         (draft) Basis spec.
2247      2. Added signatures and implementations of slices according to
2248         Basis spec.
2249      3. Edited source code throughout the system to make it compile again
2250         under 1. and 2.  (In some cases code had to be added to have it
2251         match the new signatures.)
2252      4. MLRISC should be backward-compatible: the copies of the originals
2253         of files that needed to change under 3. were retained, the .cm files
2254         check the compiler version number and use old versions when
2255         appropriate.
2256      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
2257         dirstream -> string option (in accordance with Basis spec).
2258      6. When generating code that counts lines, ml-lex used function
2259         CharVector.foldli, taking advantage of its old interface.
2260         This has been replaced with the corresponding code from
2261         CharVectorSlice.  (html-lex must be re-lexed!)
2262      7. BitArray in smlnj-lib/Util has been extended/modified to match the
2263         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
2264      8. Removed temporary additions (fromInternal, toInternal) from the
2265         (now obsolete) IntInf in smlnj-lib/Util.
2266      9. Cleaned up structure Byte.
2267     10. Added localOffset, scan, and fromString to Date (according to spec).
2268         Cleaned/corrected implementation of Date.
2269         (Still need to check for correctness; implement better canonicalizeDate.)
2270     11. Added "scan" to signature IEEE_REAL.
2271     12. Some improvements to IntInf [in particular: efficiency-hack for
2272         mod and rem when second operand is 2 (for parity checks).]
2273     13. Changed representation of type Time.time, using a single IntInf.int
2274         value counting microseconds.  This considerably simplified the
2275         implementation of structure Time.  We now support negative time
2276         values; scan and fromString handle signs.
2277     14. Functor PrimIO now takes two additional arguments (VectorSlice and
2278         ArraySlice).

2284    Description:
2285    
2286    This is a major update which comes with a version number bump
2287    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
2288    and an implementation of IntInf in the Basis.
2289    
2290    There are a fairly large number of related changes and updates throughout
2291    the system:
2292    
2293    Basis:
2294            - Implemented IntInf.
2295            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
2296            - Added some missing Real64 operations, most notably Real.toLargeInt.
2297            - Added FixedInt as a synonym for Int32.
2298    
2299    compiler:
2300            * Added support for a built-in intinf type.
2301              - literals
2302              - pattern matching
2303              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
2304              - overloading on literals and operations
2305    
2306            This required adding a primitive type intinf, some additional
2307            primops, and implementations for several non-trivial intinf
2308            operations in Core.  (The intinf type is completely abstract
2309            to the compiler; all operations get delegated back to the Core.)
2310    
2311            * Intinf equality is handled by polyequal.  However, the compiler
2312            does not print its usual warning in this case (since polyequal
2313            is the right thing to do there).
2314    
2315            * Improved the organization of structure InlineT.
2316    
2317            * A word about conversion primops:
2318            If conversions involving intinf do not cancel out during
2319            CPS contract, then the compiler must insert calls to Core functions.
2320            Since all core access must be resolved already during the FLINT
2321            translate phase, it would be too late a the time of CPS contract
2322            to add new Core calls.  For this reason, conversion primops
2323            for intinf carry two arguments:  1. the numeric argument that
2324            they are supposed to convert, and 2. the Core function that
2325            can help with this conversion if necessary.  If CPS contract
2326            eliminates a primop, then the associated Core function becomes
2327            dead and goes away.  Intinf conversion primops that do not get
2328            eliminated by CPS contract get rewritten into calls of their
2329            core functions by a separate, new phase.
2330    
2331    interactive system:
2332            - Control.Print.intinfDepth controls max length of intinf constants
2333            being printed. (Analogous to Control.Print.stringDepth.)
2334            - Cleanup in printutil and pputil: got rid of unused stuff and
2335            duplicates; replaced some of the code with code that makes better
2336            use of library functionality.
2337    
2338    CM:
2339            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
2340            are no longer silent.
2341    
2342    CKIT:
2343            Fixed mismatched uses of Int32 and LargeInt.  I always decided
2344            in favor of LargeInt -- which is now the same as IntInf.
2345            CKIT-knowledgable people should check whether this is what's
2346            intended and otherwise change things back to using Int32 or
2347            FixedInt.
2348    
2349    Throughout the code:
2350            Started using IntInf.int literals and built-in operations
2351            (e.g., comparison with 0) where this seems appropriate.

2371    Description:
2372    
2373    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
2374    
2375        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
2376    
2377    This patch restores SML/NJ's ability to run under win32.  There are a
2378    number of changes, including fixes for several bugs that had gone
2379    unnoticed until now:
2380    
2381      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
2382        trying to run the win32 version from within cygwin.)
2383    
2384      - There are a number of simple .bat scripts that substitute for their
2385        corresponding Unix shell-scripts.  (See below.)
2386    
2387      - The internals of ml-build have been modified slightly.  The main
2388        difference is that instead of calling ".link-sml" (or link-sml.bat)
2389        using OS.Process.system, the ML process delegates this task back
2390        to the script.  Otherwise problems arise in mixed environments such
2391        as Cygwin where scripts look and work like Unix scripts, but
2392        where OS.Process.system cannot run them.
2393    
2394      - In CM, the srcpath pickler used native pathname syntax -- which
2395        is incorrect in the case of cross-compilation.  The new pickle format
2396        is independent of platform-specific naming conventions.
2397    
2398      - Path configuration files (such as lib/pathconfig) can now choose
2399        between native and standard syntax.  Placing a line of the form
2400    
2401            standard!
2402    
2403        into the file causes all subsequent paths to be interpreted using
2404        CM standard pathname syntax (= Unix conventions); a line
2405    
2406            native!
2407    
2408        switches back to native style.  This was needed so that
2409        path config files can be written portably, see src/system/pathconfig.
2410    
2411      - Runtime system:
2412    
2413          - win32-filesys.c:  get_file_time and set_file_time now
2414            access modification time, not creation time.
2415    
2416          - I/O code made aware of new array representation.
2417    
2418          - Bug fixes in X86.prim.masm.
2419    
2420       - src/system/makeml made aware of win32. (For use under cygwin
2421            and other Unix-environments for windows.)
2422    
2423       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
2424         which caused BinIO.inputAll to fail consistently.
2425    
2426    .bat scripts:
2427    
2428       Windows .bat scripts assume that SMLNJ_HOME is defined.
2429    
2430       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
2431         applications (sml, ml-yacc, ml-lex).
2432       - ml-build.bat: analogous to ml-build.
2433       - config\install.bat:  Analogous to config/install.sh.  This requires
2434         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
2435         (nmake etc. must be on the path, and vcvars32 must have been run.)
2436         Moreover, sources for ml-lex and ml-yacc need to exist under src,
2437         and the bootfile hierarchy must have been unpacked under
2438         sml.boot.x86-win32.
2439         The script is very primitive and does a poor job at error checking.
2440         It only installs the base system, ml-lex, and ml-yacc.  No other
2441         libraries are being installed (i.e., you get only those that
2442         are part of the compiler.)
2443       - link-sml.bat:  analogous to .link-sml, but not currently used
2444    
2445    Unrelated bug fixes:
2446    
2447      - ml-nlffigen now exports structures ST_* corresponding to incomplete
2448        types.
2449      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
2450        otherwise.)

2479         be treated as errors (default is false).
2480      2. Cleaned up the *entire* source tree so that CMB.make goes through
2481         without a single non-exhaustive match- or bind warning.

2488    
2489    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
2490    
2491       This mainly affects the quality of error messages.  However, some
2492       of the code is now more straightforward than before. (Treatment of
2493       the above four constructs in translate.sml is much simpler than
2494       the "macro-expansion" that was going on before.  Plus, the mach-
2495       compiler no longer gets invoked just to be able to compile an
2496       if-expression.)
2497    
2498    2. The ErrorMsg.Error exception is now caught and absorbed by the
2499       interactive loop.

2506    
2507        Ported the runtime system to cygwin, which uses the unix
2508    x86-unix bin files.  Missing/buggy features:
2509    
2510       o getnetbyname, getnetbyaddr: these functions seem to be missing in
2511         the Cygwin library.
2512       o Ctrl-C handling may be flaky.
2513       o Windows system calls and Windows I/O are not supported.
2514    
2515       A new set of binfiles is located at:
2516    
2517         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
2518    
2519       This is only needed for bootstrapping the cygwin version of smlnj.

2579    
2580    In good old tradition, there has been a slight hiccup so that we have
2581    to patch 110.42 after the fact.   The old release tag has been replaced
2582    (see below).
2583    
2584    The change solves a problem with two competing approaches the
2585    configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
2586    each other's way.
2587    
2588    This change only affects the runtime system code and the installer script.

2653    Description:
2654    
2655    Fixed a bug in translation of INLMAX (and INLMIN) for the floating-point
2656    case.  (The sense of the isNaN test was reversed -- which made min and
2657    max always return their first argument.)

2671    Description:
2672    
2673    I back-ported my implementation of IEEEReal.fromString from the
2674    idlbasis-devel branch so that we can test it.
2675    
2676    Another small change is that ppDec tries to give more information
2677    than just "<sig>" in the case of functors.  However, this code is
2678    broken in some mysterious way if the functor's body's signature
2679    has not been declared by ascription but gets inferred from the
2680    implementation.  This needs fixing...

2743    
2744    - Added ControlUtil structure to control-lib.cm.
2745    - Use it throughout.
2746    - Used Controls facility to define MLRISC controls (as opposed to
2747      registering MLRISC control ref cells with Controls after the fact)
2748    - Fixed messed-up controls priorities.
2749    
2750    * Removed again all the stuff from config/preloads that one wouldn't
2751      be able to preload at the time the initial heap image is built.
2752      (Many libraries, e.g., CML, do not exist yet at this time.  The
2753       only libraries that can be preloaded via config/preloads are those
2754       that come bundled with the bootfiles.)

2779    Description:
2780    
2781    0. John Reppy made several modifications to the SML/NJ library.
2782       In particular, there is a shiny new controls-lib.cm.
2783    
2784    1. Pushed new controls interface through compiler so that everything
2785       compiles again.
2786    
2787    2. Added FormatComb and FORMAT_COMB to the CML version of the
2788       SML/NJ library (so that CML compiles again).
2789    
2790    3. Modified init scripts because XXX_DEFAULT environment variables
2791       are no longer with us.  (Boot-time initialization is now done
2792       using the same environment variables that are also used for
2793       startup-time initialization of controls.)

2799    Description:
2800    
2801            All pseudo-ops emitted before the first segment declaration
2802    such as TEXT, DATA, and BSS directives are assumed to be global
2803    declarations and are emitted first in the assembly file. This is
2804    useful in a number of situations where one has pseudo-ops that are not
2805    specific to any segment, and also works around the constraint that one
2806    cannot have client pseudo-ops in the TEXT segment.
2807    
2808            Because no segment is associated with these declarations it is
2809    an error to allocate any space or objects before the first segment
2810    directive and an exception will be raised. However, we cannot make
2811    this check for client pseudo-ops.
2812    
2813            These top level declarations are a field in the CFG graph_info.
2814    In theory you can continue to add to this field after the CFG has been
2815    built -- provided you know what you are doing;-)

2823    A few minor bugfixes:

2826        (Bogus printouts for redefined bindings still occur.  Compiler
2827        bug should no longer occur now.  We need to redo the prettyprinter
2828        from scratch.)

2838    Description:
2839    
2840    Applied the following bugfix provided by Emden Gansner:
2841    
2842        Output is corrupted when outputSubstr is used rather than output.
2843    
2844        The problem occurs when a substring
2845    
2846            ss = (s, dataStart, dataLen)
2847    
2848        where dataStart > 0, fills a stream buffer with avail bytes left.
2849        avail bytes of s, starting at index dataStart, are copied into the
2850        buffer, the buffer is flushed, and then the remaining dataLen-avail
2851        bytes of ss are copied into the beginning of the buffer. Instead of
2852        starting this copy at index dataStart+avail in s, the current code
2853        starts the copy at index avail.
2854    
2855        Fix:
2856        In text-io-fn.sml, change line 695 from
2857             val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
2858        to
2859             val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

2875    Description:
2876    
2877    Added full support for div/mod/rem/quot on the x86, using the machine
2878    instruction's two results (without clumsily recomputing the remainder)
2879    directly where appropriate.
2880    
2881    Some more extensive power-of-two support was added to the x86 instruction
2882    selector (avoiding expensive divs, mods, and muls where they can be
2883    replaced with cheaper shifts and masks).  However, this sort of thing
2884    ought to be done earlier, e.g., within the CPS optimizer so that
2885    all architectures benefit from it.
2886    
2887    The compiler compiles to a fixed point, but changes might be somewhat
2888    fragile nevertheless.  Please, report any strange things that you might
2889    see wrt. div/mod/quot/rem...

2895    Description:
2896    
2897    Fixed my broken div/mod logic.  Unfortunately, this means that the
2898    inline code for div/mod now has one more comparison than before.
2899    Fast paths (quotient > 0 or remainder = 0) are not affected, though.
2900    The problem was with quotient = 0, because that alone does not tell
2901    us which way the rounding went.  One then has to look at whether
2902    remainder and divisor have the same sign...  :(
2903    
2904    Anyway, I replaced the bootfiles with fresh ones...

2910    Description:
2911    
2912    NEW BOOTFILES!!!    Version number bumped to 110.39.3.
2913    
2914    Primops have changed. This means that the bin/boot-file formats have
2915    changed as well.
2916    
2917    To make sure that there is no confusion, I made a new version.
2918    
2919    
2920    CHANGES:
2921    
2922    * removed REMT from mltree (remainder should never overflow).
2923    
2924    * added primops to deal with divisions of all flavors to the frontend
2925    
2926    * handled these primops all the way through so they map to their respective
2927      MLRISC support
2928    
2929    * used these primops in the implementation of Int, Int32, Word, Word32
2930    
2931    * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
2932    
2933    * parameterized INLMIN, INLMAX, and INLABS by a numkind
2934    
2935    * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
2936      floating point
2937    
2938    * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
2939      and Real (but Real.abs maps to a separate floating-point-only primop)
2940    
2941    
2942    TODO items:
2943    
2944    * Hacked Alpha32 instruction selection, disabling the selection of REMx
2945      instructions because the machine instruction encoder cannot handle
2946      them.  (Hppa, PPC, and Sparc instruction selection did not handle
2947      REM in the first place, and REM is supported by the x86 machine coder.)
2948    
2949    * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
2950      selection phase.  (The two can be streamlined because the hardware
2951      delivers both quotient and remainder at the same time anyway.)
2952    
2953    * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
2954      (Currently the behavior is inconsistent both across architectures and
2955      wrt. the draft Basis spec.)
2956    
2957    * Word8 should eventually be handled natively, too.
2958    
2959    * There seems to be one serious bug in mltree-gen.sml.  It appears, though,
2960      as if there currently is no execution path that could trigger it in
2961      SML/NJ.  (The assumptions underlying functions arith and promotable do not
2962      hold for things like multiplication and division.)
