2 : blume 2237 This is the HISTORY file for the SML/NJ repository.
3 : dbm 570
4 :     An entry should be made for _every_ commit to the repository.
5 :     The entries in this file will be used when creating the README
6 :     for new versions, so keep that in mind when writing the
7 :     description.

357 :     - Aaron: fixed a number of bugs in ml-ulex.
358 :     - Matthias:
359 :     - added CM control "cm.force-tools"; this is false by default;

375 :     This should fix the problem with ckit and nlffi that was reported
376 :     by Vesa A. Norrman.

388 :     Date: 2007/05/31 14:55:00 CDT
389 :     Revision: 2650
390 :     Description:
391 :    
392 :     3rd merge of base from primop-branch-3 into the trunk.
393 :     Additional bug fixes included:
394 :    
395 :     * Timer.cpu_timer, etc. type printing corrected (by making
396 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
397 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
398 :     Stefan Monnier)

401 : blume 2645 Name: Matthias Blume (http://www.tti-c.org/blume/)
402 :     Date: 2007/05/31 11:40:00 CDT
403 :     Description:
404 :    
405 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
406 :    
407 :     Also, changed the handling of "no core access": When translate.sml
408 :     needs access to a core exception at a time when the core has not
409 :     been set up yet (this only happens when compiling system/smlnj/init/*),
410 :     then don't bother generating the corresponding tests.
411 :    
412 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
413 :     the exception. Unfortunately, that confuses the plambda type checker.
414 :     Moreover, it does not do any good, because at runtime we don't expect
415 :     such an exception to be ever raised. (The code in system/smlnj/init/*
416 :     has to be written very carefully with this in mind!)

427 :     Date: 2007/05/29 19:00:00 CDT
428 :     Description:
429 :    
430 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
431 :     with an explicit test for zero division. This should fixes several
432 :     regressions and makes it possible for downstream optimization phases
433 :     to treat these operations as "pure" when they are applied to unsigned
434 :     operands.

439 :     Description:
440 :    
441 :     Added the new MLRISC code generator for the AMD64. This version,
442 :     in contrast to the previous one, uses SSE registers and instructions
443 :     for all floating-point computations.

448 : jhr 2613 Description:
449 :    
450 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
451 :     for bugs #1415 and #1416. We also now correctly handle format characters that
452 :     lie outside the specified set.

456 :     Date: 2007/05/23 22:30:00 CDT
457 :     Description:
458 :    
459 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
460 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
461 :    
462 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
463 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
464 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
465 :     while running CMB.make. The point is that the single symbol
466 :     NO_PLUGINS is definde in all three cases.)
467 :    
468 :     I changed the three locations within the sources that get compiled
469 :     during CMB.make where ml-yacc or ml-lex input is processed: When
470 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
471 :     is bypassed.
472 :    
473 :     When bootstrapping new versions of the compiler, there can be
474 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
475 :     are not available or otherwise not operational. In this case one can
476 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
477 :     do so, the following command should be issued at the interactive
478 :     prompt:
479 :    
480 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
481 :    
482 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
483 :     files that normally would be generated by ml-yacc and ml-lex.
484 :     (Copies of these files are in the repository.)

489 :     Revision: 2603
490 :     Description:
491 :    
492 :     2nd merge of base from primop-branch-3 into the trunk.
493 :     Additional bug fixes included:
494 :     Date.scan and Date.fromString fixed;
495 :     Overloading resolution fixed and some type printing problems corrected.

500 :     Description:
501 :    
502 :     Changed the installation mechanism for CM tool plugins. These are
503 :     just libaries and now get installed like ordinary libaries.
504 :    
505 :     There are now a number of new installation targets that give some
506 :     fine-grain control over what classes and suffixes are known, and what
507 :     they will map to.
508 :     See config/targets for details.
509 :    
510 :     The code that caused plugin installation as part of running a
511 :     tool's "build" script has been removed. (The build script is for
512 :     building, not for installing.)

516 : blume 2578 Date: 2007/05/22 11:50:00 CDT
517 :     Description:
518 :    
519 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
520 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
521 :     CM fail if a shell tool reports a non-success exit status. If
522 :     the control is set to true, then CM will press on after tool failures
523 :     in the event that the target files exist (even though they are
524 :     considered outdated). Turning the control to true can be useful for
525 :     bootstrapping.

530 :     Description:
531 :    
532 :     Merge of ml-lpt revisions for 110.64.
533 :    
534 :     The name of several ml-lpt-lib modules has changed:
535 :     Repair => AntlrRepair
536 :     StreamPos => AntlrStreamPos
537 :     ErrHandlerFn => AntlrErrHandler
538 :     EBNF => AntlrEBNF
539 :    
540 :     The ml-antlr specification format has changed: declarations such as
541 :     %tokens and nonterminal definitions can occur *multiple* times in the
542 :     same specification. The semantics are such that each new declaration
543 :     extends the previous ones. This does not apply to %start or %name,
544 :     of course.
545 :    
546 :     Importing a grammar via %import now includes *all* declarations in from
547 :     the imported grammar, except for %name, %entry, and %start. Tokens
548 :     and nonterminals can be dropped using the new %dropping clause of the
549 :     %import directive; the separate %drop and %extend have been removed.
550 :    
551 :     We now allow optional type annotations on nonterminals, using the %nonterms
552 :     directive as in ml-yacc.
553 :    
554 :     The refcell construct is now implemented using SML's regular reference
555 :     cells, so the :== and !! notation has been deprecated.
556 :    
557 :     The ml-antlr tool now does much more checking of specifications, and
558 :     its error messages have been greatly improved. Error repair for
559 :     generated parsers has been completely rewritten, and is now both
560 :     much faster and more accurate.
561 :    
562 :     ml-ulex is now more lenient with escape codes (non-SML-standard
563 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
564 :     Also, character classes may now include a "-" character at the beginning
565 :     as is standard in most other regexp tools.
566 :    
567 :     All of these changes are documented in the user guide, which has
568 :     been updated and improved with this merge.

589 :     same specification. The semantics are such that each new declaration
590 :     extends the previous ones. Grammar extension constructs have also

718 :     Date: 2007/02/26
719 :     Description:
720 :    
721 :     Added preliminary support in MLRISC for Staged Allocation, a technique
722 :     for specifying calling conventions (see
723 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
724 :     Initially, we plan to use this code to generate C calls for the AMD64.
725 :    
726 :     The staged allocation code base resides in MLRISC/staged-allocation,
727 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

791 :     Date: 2007/01/31
792 :     Description:
793 :    
794 :     Brought ml-lpt manual up-to-date with the code. Many minor
795 :     improvements to the tools, and a few minor bugfixes. Prepared
796 :     ml-lpt-lib for integration with new UTF8 structure. Changed
797 :     the interface for creating streams in ml-ulex (we now support
798 :     stream creation from several kinds of sources). Overall, the
799 :     tools are now quite stable, and their interfaces are unlikely to
800 :     change in a way that would break compatibility. More work,
801 :     however, is needed in the documentation.

806 :     Description:
807 :    
808 :     Implemented library installer. Moved CM plugin code for
809 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
810 :     their respective trees. Implemented CM plugin for ml-ulex
811 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
812 :     and ml-antlr.
813 :    
814 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
815 :     CM tools. (It turns out to be too messy to do otherwise because
816 :     there is too much code that during installation relies on the presence
817 :     of these tools -- resulting in a tricky ordering problem.)

822 :     Description:
823 :    
824 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
825 :     Modified CM's startup code to use shiftArgs as it processes
826 :     command line arguments. This way, the init code in each .sml-file
827 :     or library that is mentioned at the top level will see only
828 :     those arguments that have not yet been processed at this point.
829 :     In other words, the init code can "seize control" and process the
830 :     remaining command line.

887 :    
888 :     Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to
889 :     get the c_cc termios data copied correctly. Also moved the allocation
890 :     of the string to avoid problems if it caused a GC.
891 :

896 :     Date: 2006/12/08 09:50:00 CST
897 :     Description:
898 :    
899 :     Added code to CM's "standard shell tool" implementation which
900 :     causes it to tolerate (with a warning) the situation where the shell
901 :     command fails (e.g., due to the shell command's non-existence)
902 :     as long as all target files exist.
903 :    
904 :     This makes it possible to, e.g., build ml-yacc from sources even if
905 :     svn checkout messed up the time stamps on files in such a way that
906 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
907 :     be needed to re-process yacc.grm, but obviously it might not yet be
908 :     available at that time.)

914 :    
915 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
916 :     recvVecFromNB' in the SOCKET signature. This error is actually
917 :     in the SML Basis specification too.

931 :    
932 :     Use Say.vsay for printing the "[autoloading]" message, so

934 :     to suppress them.

947 :     Tag: release-110.60
948 :     Description:
949 :    
950 :     New working release (110.60). NEW BOOTFILES!
951 :    
952 :     This is the first subversion-hosted release. There are also changes
953 :     to the directory layout. Here is a table:
954 :    
955 :     (All pathnames are relative to the SML/NJ "root" directory.)
956 :    
957 :     config -> config
958 :    
959 :     src/cm -> base/cm
960 :     src/compiler -> base/compiler
961 :     src/runtime -> base/runtime
962 :     src/system -> base/system
963 :    
964 :     src/cm/pgraph -> pgraph
965 :    
966 :     src/READMES -> base/READMES
967 :     src/$notefile -> base/NOTES/$notefile
968 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
969 :     MACOSXINSTALL WININSTALL
970 :    
971 :     src/smlnj-lib -> smlnj-lib
972 :     src/MLRISC -> MLRISC
973 :     ckit -> ckit
974 :     src/cml -> cml
975 :     src/eXene -> eXene
976 :     src/heap2asm -> heap2asm
977 :     src/lexgen -> lexgen
978 :     src/ml-burg -> ml-burg
979 :     src/ml-lex -> ml-lex
980 :     src/ml-yacc -> ml-yacc
981 :     src/ml-nlffi-lib -> nlffi/lib
982 :     src/ml-nlffigen -> nlffi/gen
983 :     src/smlnj-c -> smlnj-c
984 :     src/tools/TraceDebugProf -> trace-debug-profile
985 :    
986 :     In addition, there is also a new
987 :    
988 :     ml-lpt
989 :    
990 :     directory containing two new program generator tools: ml-ulex and
991 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
992 :     LL(k) parser generator). These tools are currently "beta-quality"
993 :    
994 :     The latest versios of the sources can now be obtained anonymously
995 :     via subversion. For this, it is useful to first check out
996 :    
997 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
998 :    
999 :     and put the resulting directory on your shell's PATH. This provides
1000 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
1001 :     and refresh-all.sh.
1002 :    
1003 :     To create a freshly checked-out copy of the sources, do
1004 :    
1005 :     checkout-all.sh [dir]
1006 :    
1007 :     where dir is the optional SML/NJ root directory (default is ".").
1008 :    
1009 :     This creates the above directory layout. Each subdirectory of
1010 :     the root is under individual subversion control. The stat-all.sh
1011 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
1012 :     each of these subtrees.
1013 :    
1014 :     ----------------------------------------------------------------------
1015 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
1016 : blume 2155 Date: 2006/11/02 12:20:00 CST
1017 :     Description:
1018 :    
1019 :     Reorganized directory layout.
1020 :    
1021 :     This is a temporary solution, more reorganization is to come.
1022 :    
1023 :     The basic idea is to have a number of toplevel trees, each corresponding
1024 :     to a well-defined part of the overall system. Each part can be
1025 :     maintained individually, even in separate source repositories,
1026 :     although currently we still serve everything out of the main
1027 :     smlnj-gforge tree.
1028 :    
1029 :     Installer and and scripts have been updated to reflect the new
1030 :     layout. The installer (base/src/system/smlnj/installer) is now
1031 :     "scriptable" to avoid burning too much knowledge about the
1032 :     layout into SML source code. The main script used by the installer
1033 :     is in config/actions.
1034 :    
1035 :     The main change is that many of the subdirectories of what used to
1036 :     be known as "src" have moved to the toplevel. The "src" directory
1037 :     itself has moved down into a subtree called "base". (We may eventually
1038 :     get rid of the extra level of indirection represented by "src".)
1039 :    
1040 :     The layout is now as follows:
1041 :    
1042 :     toplevel tree name | default repository
1043 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1044 :     -------------------+----------------------------------------------------
1045 :     config | $gf/config/trunk
1046 :     |
1047 :     base | $gf/sml/trunk
1048 :     |
1049 :     smlnj-lib | $gf/smlnj-lib/trunk
1050 :     MLRISC | $gf/MLRISC/trunk
1051 :     |
1052 :     ml-yacc | $gf/ml-yacc/trunk
1053 :     ml-lex | $gf/ml-lex/trunk
1054 :     ml-burg | $gf/ml-burg/trunk
1055 :     lexgen | $gf/lexgen/trunk
1056 :     heap2asm | $gf/heap2asm/trunk
1057 :     |
1058 :     cml | $gf/cml/trunk
1059 :     eXene | $gf/eXene/trunk
1060 :     ckit | $gf/ckit/trunk
1061 :     nlffi | $gf/nlffi/trunk
1062 :     |
1063 :     smlnj-c | $gf/smlnj-c/trunk
1064 :    
1065 :     In $gf/admin there are a few useful shell scripts for checking out
1066 :     and maintaining the entire collection of trees:
1067 :    
1068 :     admin/checkout-all.sh [dir]
1069 :     -- optionally creates dir and checks out all trees from their
1070 :     default repositories; if dir is missing, checkout into .
1071 :     admin/refresh-all.sh [dir]
1072 :     -- looks at all trees (from the above list) in dir (default: .)
1073 :     and runs "svn update" if the tree exists and is under
1074 :     subversion control;
1075 :     non-existing or non-subversion trees are skipped
1076 :     admin/stat-all.sh [dir]
1077 :     -- like refresh-all.sh, but runs "svn stat" instead

1283 :     name of the CM metadata directory from the wrong place (because
1284 :     the physical location of basis.cm has changed). Also, corrected the
1285 :     path anchor for $/html-lib.cm. (Thanks to M. Fluet for pointing out
1286 :     these problems.)

1319 :     Tag: blume-22051115-versiontool
1320 :     Description:
1321 :    
1322 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1323 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1324 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1325 :     it. Instead, it has the status of "user code", so it should use
1326 :     $/basis.cm to refer to the Basis library. (At least that's true for
1327 :     the purpose of bootstrapping the previous change. In the future it
1328 :     might make sense to have versiontool.cm refer to
1329 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1330 :     compiler itself uses.)
1331 :    
1332 :     Also patched src/system/testml to have it activate those extra anchor
1333 :     bindings in config/extrapathconfig.

1338 :     Tag: blume-22051115-libraries
1339 :     Description:
1340 :    
1341 :     This change affects the way the following libraries are tied into
1342 :     the system:
1343 :    
1344 :     $/basis.cm
1345 :     $/smlnj-lib.cm
1346 :     $/pp-lib.cm
1347 :     $/controls-lib.cm
1348 :     $/html-lib.cm
1349 :     $/ml-yacc-lib.cm
1350 :    
1351 :     These libraries are now internally (as seen from the source code
1352 :     of the implementation itself) known by the following names:
1353 :    
1354 :     $smlnj/basis/basis.cm
1355 :     $smlnj/smlnj-lib/smlnj-lib.cm
1356 :     $smlnj/smlnj-lib/pp-lib.cm
1357 :     $smlnj/smlnj-lib/controls-lib.cm
1358 :     $smlnj/smlnj-lib/html-lib.cm
1359 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1360 :    
1361 :     This makes it possible to work with code that requires different
1362 :     versions of these libraries, and which refers to these libraries using
1363 :     their "default" names (i.e., the first set of names above). In other
1364 :     words, one can un-define or re-define those default names without
1365 :     compromising the proper functioning of the compiler itself.
1366 :    
1367 :     A similar procedure had already been performed for several of the
1368 :     MLRISC libraries that are linked into the compiler. I did some
1369 :     cleanup on this code.
1370 :    
1371 :     A new file in the config directory (named extrapathconfig) is
1372 :     responsible for setting up path anchors that the compiler itself does
1373 :     not need, but that are typically required by user code.

1552 :     Tag: blume-20050516-redump-heap
1553 :     Description:
1554 :    
1555 :     Added mechanism for re-creating a heap file for the interactive system
1556 :     after configuration variables have been changed.
1557 :    
1558 :     CM.redump_heap : string -> unit
1559 :    
1560 :     This is much like SMLofNJ.exportML, but starting from the resulting
1561 : blume 2155 heap does not return to the caller of CM.redump_heap but
1562 : mblume 1792 restarts the interactive system from scratch. The original call of
1563 :     CM.redump_heap does not return but ends the interactive session.
1564 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1565 :    
1566 :     Internally, redump_heap winds the dynamic execution context back to
1567 :     the point where the original heap image was created and re-executes
1568 :     the heap image generation code in the boot code.

1684 :     Tag: blume-20050114-heap2exec
1685 :     Description:
1686 :    
1687 :     Implemented new (but still experimental) heap2exec facility. This is
1688 :     tested under Mac OS X and should work under Linux (will test shortly).
1689 :     It will probably also work on the Sparc (will test some time later).
1690 :    
1691 :     - removed old "HACKED_STANDALONE" hack from runtime
1692 :    
1693 :     To be able to test this, uncomment the request for "heap2asm" in
1694 :     config/targets prior to installation. (Notice that this is different
1695 :     from "heap2exec" mentioned below. Not a typo.)
1696 :    
1697 :     To perform an actual test, run the command
1698 :    
1699 :     $ bin/heap2exec heapfile execfile
1700 :    
1701 :     (You can put heap2exec on your shell's path.)
1702 :    
1703 :     For example, run
1704 :    
1705 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1706 :    
1707 :     This will create a standalone executable called "mly" which you can
1708 :     then invoke directly as a command.

1733 :     (The parameter-passing part of the picture has not complete. But
1734 :     data structure access seems to work.)
1735 :    
1736 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1737 :     (On the Mac, it is big-endian. And that's currently our only
1738 :     PPC platform.)

1853 :     Tag: blume-20041124-position
1854 :     Description:
1855 :    
1856 :     The compiler can now be compiled in a mode that makes structure Position
1857 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1858 :     for the time being.
1859 :    
1860 :     To enable 64-bit positions, use the following procedure:
1861 :    
1862 :     1. Start sml
1863 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1864 :     3. Type
1865 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1866 :     4. Run CMB.make() as usual.
1867 :    
1868 :     This is barely tested. The only test so far was a little SML program
1869 :     counting the number of characters in an 8-gigabyte file by
1870 :     reading it character-by-character. That test was successful.
1871 :    
1872 :     In support of 64-bit positions, a number of new functions have been
1873 :     added to the runtime system.

1918 :    
1919 :     - In a previous commit, fixed a minor issue with how polyequal is being
1920 :     translated. In particular, the code now "looks through" abstractions.
1921 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1922 :     more efficient code. Important examples for where this matters are
1923 :     the new int64 and word64 types.

1938 :     Description:
1939 :    
1940 :     All the pieces of Word64 are now there, with the exception of the
1941 :     conversions from and to LargeWord. (Eventually these need to be identities,
1942 :     but for the time being they don't even make sense because LargeWord is
1943 :     32-bit wide.)
1944 :    
1945 :     Also started to add similar support for Int64, but major pieces of that
1946 :     are still missing.

1951 :     Tag: blume-20041111-word64
1952 :     Description:
1953 :    
1954 :     Structure Word64 is now (almost) complete, word literals and patterns
1955 :     seem to work. There are a few odd pieces missing. In particular,
1956 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1957 :     at the moment.
1958 :    
1959 :     Making Word64 official would mean that LargeWord becomes Word64. But
1960 :     this requires extreme care because most word-word conversions have to
1961 :     go through LargeWord, so making a mistake means loss of efficiency or
1962 :     worse. Eventually there will be a solution similar to (but actually
1963 :     simpler than) what I did with IntInf.

2000 :     normally does not have to be edited to reflect a version change.
2001 :    
2002 :     (As a result, a version change can be done by just editing

2043 :     Tag: blume-20041020-standalone-backtrace
2044 :     Description:
2045 :    
2046 :     Added a mechanism for getting back-trace information from standalone
2047 :     programs. Here is how it works:
2048 :    
2049 :     1. The part of the program from which you want to get backtrace
2050 :     information (usually the whole program) should be wrapped with
2051 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
2052 :     main program could be modified from something like
2053 :    
2054 :     fun main (pgm, args) = ...
2055 :    
2056 :     to
2057 :    
2058 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2059 :    
2060 :     2. To be able to access BackTrace.monitor, you have to add
2061 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
2062 :     main function.
2063 :    
2064 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2065 :     CM might have created in the past for your project).
2066 :    
2067 :     4. Build the system using this command line:
2068 :    
2069 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2070 :     myprog.cm MyProg.main myprog
2071 :    
2072 :     instead of the usual
2073 :    
2074 :     ml-build myprog.cm MyProg.main myprog
2075 :    
2076 :     I changed a library name:
2077 :    
2078 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2079 :    
2080 :     New libraries:
2081 :    
2082 :     $smlnj-tdp/back-trace.cm
2083 :     -- when loaded causes the back-trace plugin to be installed
2084 :     $smlnj-tdp/coverage.cm
2085 :     -- when loaded causes the coverage plugin to be installed
2086 :

2092 :    
2093 :     Added an "obsolete" warning for the "group owner" syntax to CM's parser.
2094 :    
2095 :     Eliminated group owner specs from .cm files throughout the source tree.

2100 :     Tag: blume-20041015-coverage
2101 :     Description:
2102 :    
2103 :     * Test coverage tool added!
2104 :     * Further reorganization of tracing-, debugging-, and profiling support:
2105 :    
2106 :     - moved original BTImp -- now called BackTrace -- into a separate
2107 :     library called $/trace-debug-profile.cm
2108 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2109 :     - only the instrumentation mechanism is now left in the compiler proper
2110 :     - BackTrace module is a plugin which is NOT plugged in by default
2111 :     - Coverage module is another such plugin
2112 :    
2113 :     To get the benefits of any of these plugin modules, the code in
2114 :     question must be compiled with tdp instrumentation turned on. This
2115 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2116 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2117 :    
2118 :     Plugins are selected at link time. (Pre-compiled instrumented code
2119 :     can be re-loaded with different plugins in effect.) When an
2120 :     instrumented module is linked, whatever plugins are at that time
2121 :     enabled will come into effect for that module.
2122 :    
2123 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2124 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2125 :     To enable the coverage plugin, load the same library and invoke
2126 :     Coverage.install().
2127 :    
2128 :     Back-traces are generated automatically on uncaught exceptions and
2129 :     when the code in question explicitly invokes BackTrace.trigger().
2130 :    
2131 :     Coverage (and execution frequency-) information must be queried
2132 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2147 :     Description:
2148 :    
2149 :     Some rationalization of names:
2150 :    
2151 :     structure BTrace -> structure TDPInstrument
2152 :     etc.
2153 :    
2154 :     This is is preparation of using the original back-trace
2155 :     instrumentation for other purposes. "TDP" stands for
2156 :     Trace/Debug/Profile.
2157 :    
2158 :     The control flag controlling whether instrumentation is on or off is now
2159 :     registered under a different name, so instead of running sml as
2160 :    
2161 :     sml -Cinstrument.btrace-mode=true
2162 :    
2163 :     one has to say
2164 :

2181 :     Description:
2182 :    
2183 :     Fixed handling of keywords in .cm files: After seeing "is" the lexer
2184 :     treats subsequent occurrences of "group", "library", "source", "is",
2185 :     "*", and "-" as ordinary identifiers rather than keywords.
2186 :    
2187 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool
2188 :     is supposed to accept a tool argument called "source", but this did
2189 :     not work because of the clash with the keyword.

2232 :     Description:
2233 :    
2234 :     * Moved the "version" magic into its own little library under
2235 : mblume 1672 src/system/smlnj/internal. This avoids expensive reconstruction of
2236 :     a stable src/compiler/core.cm.
2237 : mblume 1639
2238 : mblume 1672 * At the same time, structure CompilerVersion is now known as
2239 :     structure SMLNJVersion.
2240 : mblume 1639
2241 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2242 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2243 :     Also, loading the versiontool does not work when rebuilding the system
2244 :     because CM is not properly initialized at that time.

2249 :     Tag: blume-20040929-autoversion
2250 :     Description:
2251 :    
2252 :     Implemented some CM magic to have
2253 :     file src/compiler/TopLevel/main/version.sml
2254 :     generated automagically.
2255 :     The version is taken from two files: config/version and config/release.
2256 :     The first is expected to contain a two-part version number such as 110.49.
2257 :     The second should contain a single number, but it may be missing.
2258 :    
2259 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2260 :     time the version tool is loaded (which is the first time you say CMB.make),
2261 :     then the tool will increment the value stored in config/release every
2262 :     time CMB.make is invoked.
2263 :    
2264 :     The binfile format is now insensitive to anything beyond the first
2265 :     two components of a version number, so bumping the release does not render
2266 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2267 :     during development without invalidating existing binfiles.
2268 :    
2269 :     In any case, every CMB.make updates the date information in version.sml.
2270 :     (This is the date that is printed in the banner.)

2283 :     Tag: blume-20040927-controls
2284 :     Description:
2285 :    
2286 :     Added two pieces of functionality to the Controls interface:
2287 :    
2288 :     1. val save'restore: 'a control -> unit -> unit
2289 :    
2290 :     grabs the current value of the control in stage 1 and restores it
2291 :     in stage 2.
2292 :    
2293 :     2. val set' : 'a control * 'a -> unit -> unit
2294 :    
2295 :     stores the given value into the control in stage 2 (i.e., delayed)
2296 :     but does all error checking in stage 1.
2297 :     (This is for string controls that need to do parse their argument --
2298 :     something that might fail. In some cases, notably in CM, one
2299 :     already knows the intended argument but wants to delay the actual
2300 :     assignment until a time when error recovery would be more difficult.)
2301 :    
2302 :     Changed the handling of controls in tool arguments to classes "sml" and
2303 :     "lazysml":
2304 :     - use Controls.save'restore as a more robust way of restoring the
2305 :     old value (in particular: without having to re-parse the string)
2306 :     - use controls to handle the "overload" keyword in the init group
2307 :     (I believe this change actually fixes a long-standing obscure bug.)

2312 :     Tag: blume-20040927-lazysml
2313 :     Description:
2314 :    
2315 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2316 :     difference to "sml" is that compilation is done with Control.lazysml
2317 :     set to true. A source of class "lazysml" is automatically recognized
2318 :     by a file name suffix of ".lml".
2319 :    
2320 :     In addition to the above feature, the original class "sml" now also
2321 :     supports a tool argument "lazy" which has the same effect. As a
2322 :     result, the following three lines are equivalent:
2323 :    
2324 :     foo.sml : lazysml
2325 :     foo.sml : sml (lazy)
2326 :     foo.sml (lazy)
2327 :    
2328 :     The setting goes into effect both during parsing and during
2329 :     compilation. The original setting is restored right after parsing and
2330 :     after compilation, respectively.
2331 :    
2332 :     In addition to all the above, there is also a general mechanism to set
2333 :     ANY of the "controls" that are available at the command line via
2334 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2335 :     apply as well. (In fact, "lazy" is implemented as a special case of
2336 :     the general mechanism.)
2337 :    
2338 :     The .cm file syntax uses a new keyword tool argument called "with".
2339 :     There are several ways of indicating the desired settings:
2340 :    
2341 :     foo.sml (with:parser.quotations=true)
2342 :     foo.sml (with:(name:parser.quotations value:true))
2343 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2344 :     foo.sml (with:(name1=value1 name2=value2 ...))
2345 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2346 :    
2347 :     etc.
2348 :    
2349 :     Another possible abbreviation is to leave out the =v or value:v part
2350 :     if the name refers to a boolean control (in which case the value is
2351 :     taken to be true). Thus, one could get lazy sml also by saying:
2352 :    
2353 :     foo.sml (with:parser.lazy-keyword=true)
2354 :     foo.sml (with:parser.lazy-keyword)
2355 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2356 :     foo.sml (with:(name:parser.lazy-keyword))

2708 :     Description:
2709 :    
2710 :     Changed the interface of structures Timer and Unix to match the most
2711 :     recent Basis spec.
2712 :    
2713 :     In the case of Unix there still seems to be an open/weird issue:
2714 :    
2715 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2716 :     fresh streams whenever they are called -- as opposed to have them
2717 :     return the same stream every time. This design is supposed to
2718 :     prevent space leaks caused by proc values hanging on to streams.
2719 :    
2720 :     The reap function, on the other hand, is supposed to close the
2721 :     streams. This cannot be done without having a handle on the
2722 :     stream in proc after all...
2723 :    
2724 :     I took the liberty to implement the following stopgap solution:
2725 :    
2726 :     The proc value hangs on to the most recently created stream(s).
2727 :     Reap closes those. If either or both of the two streams hadn't
2728 :     been created at all yet, then reap will close the corresponding
2729 :     file descriptors directly.
2730 :    
2731 :     PS: I don't understand the original space leak argument anymore. If
2732 :     a proc hangs on to the imperative stream, then I/O operations on those
2733 :     will advance the state of the cached stream and avoid the space leak.

2746 :     Tag: blume-20040525-group-owner
2747 :     Description:
2748 :    
2749 :     CM now ignores (but still accepts) the "owner" information in group
2750 :     descriptions. The owner of a group is its next enclosing
2751 :     library. Each group must have a unique owner. (There is a virtual
2752 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2753 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2754 :     and CM would check that such a declaration is correct. The new scheme
2755 :     is to have CM check that for each group there is precisely one owning
2756 :     library.
2757 :    
2758 :     The advantage of the new scheme is that the programmer no longer needs
2759 :     to maintain the somewhat annoying owner information. The downside is
2760 :     that CM cannot enforce the ownership rule across multiple runs of
2761 :     CM.make. Fortunately, enclosing the same group in two different
2762 :     libraries A and B which are not part of the same program does not
2763 :     cause real problems.

2787 :     gets rid of those at the end, so they don't accumulate under .cm.

2809 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
2810 :     for the voluminous patch!
2811 :    
2812 :     (I have not tested this patch under win32 yet.)
2813 :    
2814 : mblume 1490 Here is David's e-mail:
2815 :    
2816 :     Hi,
2817 :    
2818 :     Attached to this email you find a diff against sml/nj 110.45
2819 :     that will enable socket support under Windows.
2820 :    
2821 :     To apply the patch (using unix or cygwin)
2822 :     1) gunzip runtime.diff.gz
2823 :     2) "cd" into "src/runtime" in the source tree of a fresh
2824 :     110.45 installation.
2825 :     3) patch -p 1 < [your/path/to]runtime.diff
2826 :    
2827 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2828 :     I only ran a few tests for basic socket client functionality
2829 :     (which worked fine). Especially the functions that use ioctl
2830 : mblume 1490 are not tested at all and might not work (see below).
2831 :    
2832 :     I implemented this since we want to move to a newer version of sml/nj
2833 :     but need socket support in order to use it. This is the first time I
2834 :     even had a look at the sml/nj source, so please review my changes
2835 :     before making this part of the distribution! Here are a few issues
2836 : blume 2155 that I think might be better for someone to solve who is more
2837 : mblume 1490 familiar with the sml/nj source (and socket programming):
2838 :    
2839 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2840 :     exception since I could not figure out what the windows equivalent
2841 :     of these functions is
2842 :    
2843 :     - In sockets-osdep.h there are a some #include statements that are
2844 :     only used in a few files that include sockets-osdep.h
2845 :    
2846 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2847 :     does not process its return value since I don't know how to
2848 :     report an error upwards.
2849 :    
2850 :     - It would probably be good to have a call to WSACleanup() when
2851 : blume 2155 the library is unloaded (if there is such a possibility).
2852 : mblume 1490 Otherwise I think Windows will take care of this automatically
2853 :     when the process finishes.
2854 :    
2855 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2856 :     no idea if that is actually the proper replacement on Windows.
2857 :    
2858 :     - All these issues are marked in the code by "FIXME" comments.
2859 :    
2860 : blume 2155 We use sml/nj extensively in our products and are quite happy
2861 :     with it. I hope this contribution will help you.
2862 : mblume 1490
2863 :     Keep up the good work!

2898 :     Description:
2899 :    
2900 :     The installer now honors the "src-smlnj" target again, although its meaning
2901 :     has changed from "all sources required for the compiler" to "all sources
2902 :     the installer knows about". In other words, if you enable "src-smlnj"
2903 :     in the "targets" file, then the installer will pull in sources for
2904 :     everything. (Notice that this refers to source code only. Compiled
2905 :     code is still only installed for modules that were requested explicitly
2906 :     or which are required for other modules that were requested explicitly.)

2940 :     Description:
2941 :    
2942 :     Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
2943 :     of SML/NJ. The problem is that
2944 :    
2945 :     lib = dlopen(NULL, ...)
2946 :     f = dlsym(lib, "malloc");
2947 :    
2948 : blume 2155 does not work on Windows unless we explicitly export symbols
2949 :     such as 'malloc' during linking. We fixed this by explicitly
2950 : allenleung 1468 exporting the required symbols with the magic gcc incantation:
2951 :    
2952 :     -Wl,--export-all cygwin.def
2953 :    
2954 :     where cygwin.def is a file containing all the symbols that
2955 : blume 2155 we wish to export.
2956 : allenleung 1468
2957 : blume 2155 I suspect this is a Windows problem and we'll have to
2958 :     do the same (somehow with windows compilers) when
2959 : allenleung 1468 we build the native win32 version with the system
2960 : blume 2155 calls LoadLibrary/GetProcAddress.

3029 :    
3030 :     Eliminated the "dont_move_libraries" directive in config/targets.
3031 :     (The mechanism was broken and could not be fixed easily. Moreover,
3032 :     there does not seem to be any reason not to move all libraries into
3033 :     lib during installation. I originally implemented this directive as a
3034 :     backward-compatibility feature when I first introduced the new CM.
3035 :     Now that things have been stable for a long time and going back to the
3036 :     old CM is not an option, there is no reason to keep it around.)

3085 :     Tag: blume-20030926-ppautoload
3086 :     Description:
3087 :    
3088 :     I modified the read-eval-print loop so that the autoloader gets
3089 :     invoked whenever the prettyprinter tries to look up a symbol that
3090 :     is not currently defined in the toplevel environment but which
3091 :     appears in CM's autoload registry. As a result, we see far fewer of
3092 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3093 :    
3094 :     In addition to this I tried to clean up some pieces of the Basis
3095 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3096 :     instances of these ?.Foo.Bar.xxx names from being printed.
3097 :    
3098 :     The mechanism that picks names for types still needs some work, though.
3099 :     (Right now it seems that if there is a type A.t which is defined to
3100 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3101 :     "?.B.u" although the perhaps more sensible solution would be to use
3102 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3103 :     a chain of DEFtycs not farther than there are corresponding toplevel
3104 :     names in the current environment.)

3110 :     Description:
3111 :    
3112 :     Another installer tweak: All the ML code for the installer is now
3113 :     compiled during CMB.make and put into a little library called
3114 :     $smlnj/installer.cm. The installation then simply invokes
3115 :    
3116 :     sml -m $smlnj/installer.cm
3117 :    
3118 :     and everything happens automagically.
3119 :    
3120 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3121 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3122 :     and BINDIR.
3123 :    
3124 :     The new scheme guarantees that the ML code responsible for the installation
3125 :     is in sync with the APIs of the main system. Also, the installer is
3126 :     somewhat faster because the installer script is precompiled.

3135 :     but excludes all non-blocking operations. Defined SOCKET (in Basis)
3136 :     and CML_SOCKET in terms of SYNCHRONOUS_SOCKET. Removed superfluous

3138 :     structure.

3143 :     Tag: blume-20030924-sockets
3144 :     Description:
3145 :    
3146 :     1. Fixed SOCKET API and implementation to match Basis spec.
3147 :     This required changing the internal representation of sockets to one
3148 :     that remembers (for each socket file descriptor) whether it is currently
3149 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3150 :     call is made only if the state actually needs to change).
3151 :    
3152 :     2. OS-specific details of sockets were moved into separate files, thus
3153 :     making it possible to unify the bulk of the socket implementations
3154 :     between Unix and Win32.
3155 :    
3156 :     3. CML's socket API changed accordingly.
3157 :     (Note that we need to remove non-blocking functions from this API
3158 :     since they are redundant in the case of CML!)
3159 :    
3160 :     4. CML's socket implementation now makes use of non-blocking functions
3161 :     provided by Basis, thus removing all OS-dependent code from this part
3162 :     of CML.
3163 :    
3164 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3276 :     Tag: blume-20030909-installer
3277 :     Description:
3278 :    
3279 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3280 :     Modified config/install.bat to take advantage of it. Also modified
3281 :     config/install.sh (and called it config/new-install.sh) to take advantage
3282 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3283 :     independent.)
3284 :    
3285 :     The installer can now install everything under Win32
3286 :     as well as under *nix as long as it compiles.
3287 :    
3288 :     Other changes:
3289 :    
3290 :     - made CML compile again under Win32
3291 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3292 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3293 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3294 :     same as type int; under Win32 it isn't
3295 :     - fixed some slice-related problems in the win32-specific parts of CML
3296 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3297 :     (under Win32, the volume name is case-insensitive, and the
3298 :     OS.Path code compares volume names for equality)

3304 :     Description:
3305 :    
3306 :     Made Win32 version of OS.FileSys.fullPath return current directory
3307 :     when given an empty string. This is what the spec says, and incidentally,
3308 :     CM depends on it. (CM otherwise goes into an infinite loop in certain
3309 :     cases when presented with the name of a non-existing .cm file.)

3314 : mblume 1352 Tag: blume-20030905-slices-etc
3315 : mblume 1350 Description:
3316 :    
3317 :     1. Changed interface to vectors and arrays in Basis to match
3318 :     (draft) Basis spec.
3319 :     2. Added signatures and implementations of slices according to
3320 :     Basis spec.
3321 :     3. Edited source code throughout the system to make it compile again
3322 :     under 1. and 2. (In some cases code had to be added to have it
3323 :     match the new signatures.)
3324 :     4. MLRISC should be backward-compatible: the copies of the originals
3325 :     of files that needed to change under 3. were retained, the .cm files
3326 :     check the compiler version number and use old versions when
3327 :     appropriate.
3328 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3329 :     dirstream -> string option (in accordance with Basis spec).
3330 :     6. When generating code that counts lines, ml-lex used function
3331 :     CharVector.foldli, taking advantage of its old interface.
3332 :     This has been replaced with the corresponding code from
3333 :     CharVectorSlice. (html-lex must be re-lexed!)
3334 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3335 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3336 :     8. Removed temporary additions (fromInternal, toInternal) from the
3337 :     (now obsolete) IntInf in smlnj-lib/Util.
3338 :     9. Cleaned up structure Byte.
3339 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3340 :     Cleaned/corrected implementation of Date.
3341 :     (Still need to check for correctness; implement better canonicalizeDate.)
3342 :     11. Added "scan" to signature IEEE_REAL.
3343 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3344 :     mod and rem when second operand is 2 (for parity checks).]
3345 :     13. Changed representation of type Time.time, using a single IntInf.int
3346 :     value counting microseconds. This considerably simplified the
3347 :     implementation of structure Time. We now support negative time
3348 :     values; scan and fromString handle signs.
3349 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3350 :     ArraySlice).

3355 :     Tag: blume-20030828-intinf
3356 :     Description:
3357 :    
3358 :     This is a major update which comes with a version number bump
3359 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3360 :     and an implementation of IntInf in the Basis.
3361 :    
3362 :     There are a fairly large number of related changes and updates throughout
3363 :     the system:
3364 :    
3365 :     Basis:
3366 :     - Implemented IntInf.
3367 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3368 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3369 : mblume 1347 - Added FixedInt as a synonym for Int32.
3370 :    
3371 :     compiler:
3372 :     * Added support for a built-in intinf type.
3373 :     - literals
3374 :     - pattern matching
3375 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3376 :     - overloading on literals and operations
3377 :    
3378 :     This required adding a primitive type intinf, some additional
3379 :     primops, and implementations for several non-trivial intinf
3380 :     operations in Core. (The intinf type is completely abstract
3381 :     to the compiler; all operations get delegated back to the Core.)
3382 :    
3383 :     * Intinf equality is handled by polyequal. However, the compiler
3384 :     does not print its usual warning in this case (since polyequal
3385 :     is the right thing to do there).
3386 :    
3387 :     * Improved the organization of structure InlineT.
3388 :    
3389 :     * A word about conversion primops:
3390 :     If conversions involving intinf do not cancel out during
3391 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3392 : mblume 1347 Since all core access must be resolved already during the FLINT
3393 :     translate phase, it would be too late a the time of CPS contract
3394 : mblume 1348 to add new Core calls. For this reason, conversion primops
3395 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3396 :     they are supposed to convert, and 2. the Core function that
3397 :     can help with this conversion if necessary. If CPS contract
3398 : mblume 1348 eliminates a primop, then the associated Core function becomes
3399 :     dead and goes away. Intinf conversion primops that do not get
3400 :     eliminated by CPS contract get rewritten into calls of their
3401 :     core functions by a separate, new phase.
3402 : mblume 1347
3403 :     interactive system:
3404 :     - Control.Print.intinfDepth controls max length of intinf constants
3405 :     being printed. (Analogous to Control.Print.stringDepth.)
3406 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3407 :     duplicates; replaced some of the code with code that makes better
3408 :     use of library functionality.
3409 :    
3410 :     CM:
3411 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3412 :     are no longer silent.
3413 :    
3414 :     CKIT:
3415 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3416 :     in favor of LargeInt -- which is now the same as IntInf.
3417 :     CKIT-knowledgable people should check whether this is what's
3418 :     intended and otherwise change things back to using Int32 or
3419 :     FixedInt.
3420 :    
3421 :     Throughout the code:
3422 : mblume 1348 Started using IntInf.int literals and built-in operations
3423 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3432 :     Merging changes from the mcz-branch development branch into trunk.
3433 :     These changes involve replacement of the emulated old prettyprinter
3434 :     interface with direct use of the SML/NJ Lib PP library, and fixing
3435 :     of a couple of bugs (895, 1186) relating to error messages. A new

3441 : mblume 1342 Date: 2003/08/11 15:45:00 CDT
3442 :     Tag: blume-20030811-windows
3443 :     Description:
3444 :    
3445 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3446 :    
3447 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3448 :    
3449 :     This patch restores SML/NJ's ability to run under win32. There are a
3450 :     number of changes, including fixes for several bugs that had gone
3451 :     unnoticed until now:
3452 :    
3453 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3454 :     trying to run the win32 version from within cygwin.)
3455 :    
3456 :     - There are a number of simple .bat scripts that substitute for their
3457 :     corresponding Unix shell-scripts. (See below.)
3458 :    
3459 :     - The internals of ml-build have been modified slightly. The main
3460 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3461 :     using OS.Process.system, the ML process delegates this task back
3462 :     to the script. Otherwise problems arise in mixed environments such
3463 :     as Cygwin where scripts look and work like Unix scripts, but
3464 :     where OS.Process.system cannot run them.
3465 :    
3466 :     - In CM, the srcpath pickler used native pathname syntax -- which
3467 :     is incorrect in the case of cross-compilation. The new pickle format
3468 :     is independent of platform-specific naming conventions.
3469 :    
3470 :     - Path configuration files (such as lib/pathconfig) can now choose
3471 :     between native and standard syntax. Placing a line of the form
3472 :    
3473 :     standard!
3474 :    
3475 :     into the file causes all subsequent paths to be interpreted using
3476 :     CM standard pathname syntax (= Unix conventions); a line
3477 :    
3478 :     native!
3479 :    
3480 :     switches back to native style. This was needed so that
3481 :     path config files can be written portably, see src/system/pathconfig.
3482 :    
3483 :     - Runtime system:
3484 :    
3485 :     - win32-filesys.c: get_file_time and set_file_time now
3486 :     access modification time, not creation time.
3487 :    
3488 :     - I/O code made aware of new array representation.
3489 :    
3490 :     - Bug fixes in X86.prim.masm.
3491 :    
3492 :     - src/system/makeml made aware of win32. (For use under cygwin
3493 :     and other Unix-environments for windows.)
3494 :    
3495 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3496 :     which caused BinIO.inputAll to fail consistently.
3497 :    
3498 :     .bat scripts:
3499 :    
3500 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3501 :    
3502 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3503 :     applications (sml, ml-yacc, ml-lex).
3504 :     - ml-build.bat: analogous to ml-build.
3505 :     - config\install.bat: Analogous to config/install.sh. This requires
3506 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3507 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3508 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3509 :     and the bootfile hierarchy must have been unpacked under
3510 :     sml.boot.x86-win32.
3511 :     The script is very primitive and does a poor job at error checking.
3512 :     It only installs the base system, ml-lex, and ml-yacc. No other
3513 :     libraries are being installed (i.e., you get only those that
3514 :     are part of the compiler.)
3515 :     - link-sml.bat: analogous to .link-sml, but not currently used
3516 :    
3517 :     Unrelated bug fixes:
3518 :    
3519 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3520 :     types.
3521 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3522 :     otherwise.)

3546 :     Description:
3547 :    
3548 :     Two changes:
3549 :    
3550 :     1. Added a flag for controlling whether non-exhaustive bindings will
3551 :     be treated as errors (default is false).
3552 :     2. Cleaned up the *entire* source tree so that CMB.make goes through
3553 :     without a single non-exhaustive match- or bind warning.

3559 :     Description:
3560 :    
3561 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3562 :    
3563 :     This mainly affects the quality of error messages. However, some
3564 :     of the code is now more straightforward than before. (Treatment of
3565 :     the above four constructs in translate.sml is much simpler than
3566 :     the "macro-expansion" that was going on before. Plus, the mach-
3567 :     compiler no longer gets invoked just to be able to compile an
3568 :     if-expression.)
3569 :    
3570 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3571 :     interactive loop.

3578 :    
3579 : blume 2155 Ported the runtime system to cygwin, which uses the unix

3581 :    
3582 : blume 2155 o getnetbyname, getnetbyaddr: these functions seem to be missing in
3583 : allenleung 1327 the Cygwin library.
3584 :     o Ctrl-C handling may be flaky.
3585 :     o Windows system calls and Windows I/O are not supported.

3587 :     A new set of binfiles is located at:
3588 :    
3589 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3590 :    
3591 :     This is only needed for bootstrapping the cygwin version of smlnj.

3634 :     change their identity (e.g., by getting unlinked and recreated by some
3635 :     text editor such as vi). There might be a better/cheaper/cleaner way

3675 :     Description:
3676 :    
3677 :     The mltree operator DIVS must be implemented with an overflow check on
3678 :     the PPC because the hardware indicates divide-by-zero using "overflow" as

3685 :     Description:
3686 :    
3687 :     Sml now senses the SMLNJ_HOME environment variable. If this is set,
3688 :     then the bin dir is assumed to be in $SMLNJ_HOME/bin and (unless
3689 :     CM_PATHCONFIG is also set), the path configuration file is assumed
3690 :     to be in $SMLNJ_HOME/lib/pathconfig. This way one can easily move
3691 :     the entire tree to some other place and everything will "just work".
3692 :    
3693 :     (Companion commands such as ml-build and ml-makedepend also sense this
3694 :     variable.)

3747 :    
3748 :     Another small change is that ppDec tries to give more information
3749 :     than just "<sig>" in the case of functors. However, this code is
3750 :     broken in some mysterious way if the functor's body's signature
3751 :     has not been declared by ascription but gets inferred from the
3752 :     implementation. This needs fixing...

3820 :     - Fixed messed-up controls priorities.
3821 :    
3822 :     * Removed again all the stuff from config/preloads that one wouldn't
3823 :     be able to preload at the time the initial heap image is built.
3824 :     (Many libraries, e.g., CML, do not exist yet at this time. The

3852 :    
3853 :     0. John Reppy made several modifications to the SML/NJ library.
3854 :     In particular, there is a shiny new controls-lib.cm.
3855 :    
3856 :     1. Pushed new controls interface through compiler so that everything
3857 :     compiles again.
3858 :    
3859 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3860 :     SML/NJ library (so that CML compiles again).
3861 :    
3862 :     3. Modified init scripts because XXX_DEFAULT environment variables
3863 :     are no longer with us. (Boot-time initialization is now done
3864 :     using the same environment variables that are also used for
3865 :     startup-time initialization of controls.)

3871 :     Description:
3872 :    
3873 :     All pseudo-ops emitted before the first segment declaration
3874 :     such as TEXT, DATA, and BSS directives are assumed to be global
3875 :     declarations and are emitted first in the assembly file. This is
3876 :     useful in a number of situations where one has pseudo-ops that are not
3877 :     specific to any segment, and also works around the constraint that one
3878 :     cannot have client pseudo-ops in the TEXT segment.
3879 :    
3880 :     Because no segment is associated with these declarations it is
3881 :     an error to allocate any space or objects before the first segment
3882 :     directive and an exception will be raised. However, we cannot make
3883 :     this check for client pseudo-ops.
3884 :    
3885 :     These top level declarations are a field in the CFG graph_info.
3886 :     In theory you can continue to add to this field after the CFG has been
3887 :     built -- provided you know what you are doing;-)

3900 :     from scratch.)

3910 :     Description:
3911 :    
3912 :     Applied the following bugfix provided by Emden Gansner:
3913 :    
3914 :     Output is corrupted when outputSubstr is used rather than output.
3915 :    
3916 : blume 2155 The problem occurs when a substring
3917 : blume 1189
3918 :     ss = (s, dataStart, dataLen)
3919 :    
3920 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3921 :     avail bytes of s, starting at index dataStart, are copied into the
3922 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3923 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3924 :     starting this copy at index dataStart+avail in s, the current code
3925 : blume 1189 starts the copy at index avail.
3926 :    
3927 :     Fix:
3928 :     In text-io-fn.sml, change line 695 from
3929 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3930 : blume 2155 to
3931 : blume 1189 val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

3947 :     Description:
3948 :    
3949 :     Added full support for div/mod/rem/quot on the x86, using the machine
3950 :     instruction's two results (without clumsily recomputing the remainder)
3951 :     directly where appropriate.
3952 :    
3953 :     Some more extensive power-of-two support was added to the x86 instruction
3954 :     selector (avoiding expensive divs, mods, and muls where they can be
3955 :     replaced with cheaper shifts and masks). However, this sort of thing
3956 :     ought to be done earlier, e.g., within the CPS optimizer so that
3957 :     all architectures benefit from it.
3958 :    
3959 :     The compiler compiles to a fixed point, but changes might be somewhat
3960 :     fragile nevertheless. Please, report any strange things that you might
3961 :     see wrt. div/mod/quot/rem...

3969 :     Fixed my broken div/mod logic. Unfortunately, this means that the

3971 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3972 :     The problem was with quotient = 0, because that alone does not tell
3973 :     us which way the rounding went. One then has to look at whether
3974 :     remainder and divisor have the same sign... :(

3983 :    
3984 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
3985 :    
3986 :     Primops have changed. This means that the bin/boot-file formats have
3987 :     changed as well.
3988 :    
3989 :     To make sure that there is no confusion, I made a new version.
3990 :    
3991 :    
3992 :     CHANGES:
3993 :    
3994 :     * removed REMT from mltree (remainder should never overflow).
3995 :    
3996 :     * added primops to deal with divisions of all flavors to the frontend
3997 :    
3998 :     * handled these primops all the way through so they map to their respective
3999 :     MLRISC support
4000 :    
4001 :     * used these primops in the implementation of Int, Int32, Word, Word32
4002 :    
4003 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
4004 :    
4005 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
4006 :    
4007 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
4008 :     floating point
4009 :    
4010 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
4011 :     and Real (but Real.abs maps to a separate floating-point-only primop)
4012 :    
4013 :    
4014 :     TODO items:
4015 :    
4016 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
4017 :     instructions because the machine instruction encoder cannot handle
4018 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
4019 :     REM in the first place, and REM is supported by the x86 machine coder.)
4020 :    
4021 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
4022 :     selection phase. (The two can be streamlined because the hardware
4023 :     delivers both quotient and remainder at the same time anyway.)
4024 :    
4025 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
4026 :     (Currently the behavior is inconsistent both across architectures and
4027 :     wrt. the draft Basis spec.)
4028 :    
4029 :     * Word8 should eventually be handled natively, too.
4030 :    
4031 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
4032 :     as if there currently is no execution path that could trigger it in
4033 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
4034 :     hold for things like multiplication and division.)

4039 :     Tag: blume-20020327-mlrisc-divisions
4040 :     Description:
4041 :    
4042 :     Added support for all four division operations (ML's div, mod, quot,
4043 :     and rem) to MLRISC. In the course of doing so, I also rationalized
4044 :     the naming (no more annoying switch-around of DIV and QUOT), by
4045 :     parameterizing the operation by div_rounding_mode (which can be either
4046 :     DIV_TO_ZERO or DIV_TO_NEGINF).
4047 :    
4048 :     The generic MLTreeGen functor takes care of compiling all four
4049 :     operations down to only round-to-zero div.
4050 :    
4051 :     Missing pieces:
4052 :    
4053 :     * Doing something smarter than relying on MLTreeGen on architectures
4054 :     like, e.g., the x86 where hardware division delivers both quotient and
4055 :     remainder at the same time. With this, the implementation of the
4056 :     round-to-neginf operations could be further streamlined.
4057 :    
4058 :     * Remove inlining support for div/mod/rem from the frontend and replace it
4059 :     with primops that get carried through to the backend. Do this for all
4060 :     int and word types.

4065 :     Tag: blume-20020325-divmod
4066 :     Description:
4067 :    
4068 :     I improved (hopefully without breaking them) the implementation of Int.div,
4069 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
4070 :     advantage of the following observations:
4071 :    
4072 :     Let q = x quot y r = x rem y
4073 :     d = x div y m = x mod y
4074 :    
4075 :     where "quot" is the round-to-zero version of integer division that
4076 :     hardware usually provides. Then we have:
4077 :    
4078 :     r = x - q * y where neither the * nor the - will overflow
4079 :     d = if q >= 0 orelse x = q * y then q else q - 1
4080 :     where neither the * nor the - will overflow
4081 :     m = if q >= 0 orelse r = 0 then r else r + y
4082 :     where the + will not overflow
4083 :    
4084 :     This results in substantial simplification of the generated code.
4085 :     The following table shows the number of CFG nodes and edges generated
4086 :     for
4087 :     fun f (x, y) = x OPER y
4088 :     (* with OPER \in div, mod, quot, rem *)
4089 :    
4090 :    
4091 :     OPER | nodes(old) | edges(old) | nodes(new) | edges(new)

4111 :     Description:
4112 :    
4113 :     I did some cleanup to Allen's new primop code and
4114 :     replaced yesterday's bootfiles with new ones.
4115 :     (But they are stored in the same place.)

4129 :     Description:
4130 :    
4131 :     1. Changes to FLINT primops:
4132 :    
4133 :     (* make a call to a C-function;
4134 :     * The primop carries C function prototype information and specifies
4135 :     * which of its (ML-) arguments are floating point. C prototype
4136 :     * information is for use by the backend, ML information is for
4137 :     * use by the CPS converter. *)
4138 :     | RAW_CCALL of { c_proto: CTypes.c_proto,
4139 :     ml_args: ccall_type list,
4140 :     ml_res_opt: ccall_type option,
4141 :     reentrant : bool
4142 :     } option
4143 :     (* Allocate uninitialized storage on the heap.
4144 :     * The record is meant to hold short-lived C objects, i.e., they
4145 : blume 2155 * are not ML pointers. With the tag, the representation is
4146 : leunga 1174 * the same as RECORD with tag tag_raw32 (sz=4), or tag_fblock (sz=8)
4147 :     *)
4148 : blume 2155 | RAW_RECORD of {tag:bool,sz:int}
4149 : leunga 1174 and ccall_type = CCALL_INT32 | CCALL_REAL64 | CCALL_ML_PTR
4150 :    
4151 :     2. These CPS primops are now overloaded:
4152 :    
4153 :     rawload of {kind:numkind}
4154 :     rawstore of {kind:numkind}
4155 :    
4156 :     The one argument form is:
4157 :    
4158 :     rawload {kind} address
4159 :    
4160 :     The two argument form is:
4161 : blume 2155
4162 : leunga 1174 rawload {kind} [ml object, byte-offset]
4163 :    
4164 :     3. RAW_CCALL/RCC now takes two extra arguments:
4165 :    
4166 :     a. The first is whether the C call is reentrant, i.e., whether
4167 :     ML state should be saved and restored.
4168 :     b. The second argument is a string argument specifying the name of
4169 :     library and the C function.
4170 :    
4171 :     These things are currently not handled in the code generator, yet.
4172 :    
4173 :     4. In CProto,
4174 :    
4175 : blume 2155 An encoding type of "bool" means "ml object" and is mapped into
4176 :     C prototype of PTR. Note that "bool" is different than "string",
4177 : leunga 1174 even though "string" is also mapped into PTR, because "bool"
4178 :     is assigned an CPS type of BOGt, while "string" is assigned INT32t.
4179 :    
4180 :     5. Pickler/unpicker
4181 :    
4182 :     Changed to handle RAW_RECORD and newest RAW_CCALL
4183 :    
4184 :     6. MLRiscGen,
4185 :    
4186 :     1. Changed to handle the new rawload/rawstore/rawrecord operators.
4187 :     2. Code for handling C Calls has been moved to a new module CPSCCalls,
4188 :     in the file CodeGen/cpscompile/cps-c-calls.sml
4189 :    
4190 :     7. Added the conditional move operator
4191 :    
4192 :     condmove of branch
4193 :    
4194 : blume 2155 to cps. Generation of this is still buggy so it is currently
4195 : leunga 1174 disabled.
