357 :     Date: 2007/05/31 14:55:00 CDT
358 :     Revision: 2650
359 :     Description:
360 :    
361 :     3rd merge of base from primop-branch-3 into the trunk.
362 :     Additional bug fixes included:
363 :    
364 :     * Timer.cpu_timer, etc. type printing corrected (by making
365 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
366 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
367 :     Stefan Monnier)
368 :    
369 :     ----------------------------------------------------------------------
370 : blume 2645 Name: Matthias Blume (http://www.tti-c.org/blume/)
371 :     Date: 2007/05/31 11:40:00 CDT
372 :     Description:
373 :    
374 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
375 :    
376 :     Also, changed the handling of "no core access": When translate.sml
377 :     needs access to a core exception at a time when the core has not
378 :     been set up yet (this only happens when compiling system/smlnj/init/*),
379 :     then don't bother generating the corresponding tests.
380 :    
381 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
382 :     the exception. Unfortunately, that confuses the plambda type checker.
383 :     Moreover, it does not do any good, because at runtime we don't expect
384 :     such an exception to be ever raised. (The code in system/smlnj/init/*
385 :     has to be written very carefully with this in mind!)

396 :     Date: 2007/05/29 19:00:00 CDT
397 :     Description:
398 :    
399 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
400 :     with an explicit test for zero division. This should fixes several
401 :     regressions and makes it possible for downstream optimization phases
402 :     to treat these operations as "pure" when they are applied to unsigned
403 :     operands.

408 :     Description:
409 :    
410 :     Added the new MLRISC code generator for the AMD64. This version,
411 :     in contrast to the previous one, uses SSE registers and instructions
412 :     for all floating-point computations.

418 :    
419 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
420 :     for bugs #1415 and #1416. We also now correctly handle format characters that
421 :     lie outside the specified set.

424 : blume 2610 Name: Matthias Blume (http://www.tti-c.org/blume/)
425 :     Date: 2007/05/23 22:30:00 CDT
426 :     Description:
427 :    
428 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
429 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
430 :    
431 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
432 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
433 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
434 :     while running CMB.make. The point is that the single symbol
435 :     NO_PLUGINS is definde in all three cases.)
436 :    
437 :     I changed the three locations within the sources that get compiled
438 :     during CMB.make where ml-yacc or ml-lex input is processed: When
439 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
440 :     is bypassed.
441 :    
442 :     When bootstrapping new versions of the compiler, there can be
443 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
444 :     are not available or otherwise not operational. In this case one can
445 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
446 :     do so, the following command should be issued at the interactive
447 :     prompt:
448 :    
449 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
450 :    
451 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
452 :     files that normally would be generated by ml-yacc and ml-lex.
453 :     (Copies of these files are in the repository.)

459 :     Description:
460 :    
461 :     2nd merge of base from primop-branch-3 into the trunk.
462 :     Additional bug fixes included:
463 :     Date.scan and Date.fromString fixed;

469 :     Description:
470 :    
471 :     Changed the installation mechanism for CM tool plugins. These are
472 :     just libaries and now get installed like ordinary libaries.
473 :    
474 :     There are now a number of new installation targets that give some
475 :     fine-grain control over what classes and suffixes are known, and what
476 :     they will map to.
477 :     See config/targets for details.
478 :    
479 :     The code that caused plugin installation as part of running a
480 :     tool's "build" script has been removed. (The build script is for
481 :     building, not for installing.)

486 :     Description:
487 :    
488 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
489 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
490 :     CM fail if a shell tool reports a non-success exit status. If
491 :     the control is set to true, then CM will press on after tool failures
492 :     in the event that the target files exist (even though they are
493 :     considered outdated). Turning the control to true can be useful for
494 :     bootstrapping.

499 :     Description:
500 :    
501 :     Merge of ml-lpt revisions for 110.64.
502 :    
503 :     The name of several ml-lpt-lib modules has changed:
504 :     Repair => AntlrRepair
505 :     StreamPos => AntlrStreamPos
506 :     ErrHandlerFn => AntlrErrHandler
507 :     EBNF => AntlrEBNF
508 :    
509 :     The ml-antlr specification format has changed: declarations such as
510 :     %tokens and nonterminal definitions can occur *multiple* times in the
511 :     same specification. The semantics are such that each new declaration
512 :     extends the previous ones. This does not apply to %start or %name,
513 :     of course.
514 :    
515 :     Importing a grammar via %import now includes *all* declarations in from
516 :     the imported grammar, except for %name, %entry, and %start. Tokens
517 :     and nonterminals can be dropped using the new %dropping clause of the
518 :     %import directive; the separate %drop and %extend have been removed.
519 :    
520 :     We now allow optional type annotations on nonterminals, using the %nonterms
521 :     directive as in ml-yacc.
522 :    
523 :     The refcell construct is now implemented using SML's regular reference
524 :     cells, so the :== and !! notation has been deprecated.
525 :    
526 :     The ml-antlr tool now does much more checking of specifications, and
527 :     its error messages have been greatly improved. Error repair for
528 :     generated parsers has been completely rewritten, and is now both
529 :     much faster and more accurate.
530 :    
531 :     ml-ulex is now more lenient with escape codes (non-SML-standard
532 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
533 :     Also, character classes may now include a "-" character at the beginning
534 :     as is standard in most other regexp tools.
535 :    
536 :     All of these changes are documented in the user guide, which has
537 :     been updated and improved with this merge.

687 :     Date: 2007/02/26
688 :     Description:
689 :    
690 :     Added preliminary support in MLRISC for Staged Allocation, a technique
691 :     for specifying calling conventions (see
692 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
693 :     Initially, we plan to use this code to generate C calls for the AMD64.
694 :    
695 :     The staged allocation code base resides in MLRISC/staged-allocation,
696 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

717 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
718 :     of the range -128 ... 127. I've changed the code so that the range

760 :     Date: 2007/01/31
761 :     Description:
762 :    
763 :     Brought ml-lpt manual up-to-date with the code. Many minor
764 :     improvements to the tools, and a few minor bugfixes. Prepared
765 :     ml-lpt-lib for integration with new UTF8 structure. Changed
766 :     the interface for creating streams in ml-ulex (we now support
767 :     stream creation from several kinds of sources). Overall, the
768 :     tools are now quite stable, and their interfaces are unlikely to
769 :     change in a way that would break compatibility. More work,
770 :     however, is needed in the documentation.

774 : blume 2298 Date: 2007/02/01 10:05:00 CST
775 :     Description:
776 :    
777 :     Implemented library installer. Moved CM plugin code for
778 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
779 :     their respective trees. Implemented CM plugin for ml-ulex
780 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
781 :     and ml-antlr.
782 :    
783 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
784 :     CM tools. (It turns out to be too messy to do otherwise because
785 :     there is too much code that during installation relies on the presence
786 :     of these tools -- resulting in a tricky ordering problem.)

791 :     Description:
792 :    
793 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
794 :     Modified CM's startup code to use shiftArgs as it processes
795 :     command line arguments. This way, the init code in each .sml-file
796 :     or library that is mentioned at the top level will see only
797 :     those arguments that have not yet been processed at this point.
798 :     In other words, the init code can "seize control" and process the
799 :     remaining command line.

865 :     Date: 2006/12/08 09:50:00 CST
866 :     Description:
867 :    
868 :     Added code to CM's "standard shell tool" implementation which
869 :     causes it to tolerate (with a warning) the situation where the shell
870 :     command fails (e.g., due to the shell command's non-existence)
871 :     as long as all target files exist.
872 :    
873 :     This makes it possible to, e.g., build ml-yacc from sources even if
874 :     svn checkout messed up the time stamps on files in such a way that
875 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
876 :     be needed to re-process yacc.grm, but obviously it might not yet be
877 :     available at that time.)

882 :     Description:
883 :    
884 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
885 :     recvVecFromNB' in the SOCKET signature. This error is actually
886 :     in the SML Basis specification too.

891 :     Description:
892 :

900 :    
901 :     Use Say.vsay for printing the "[autoloading]" message, so
902 :     #set CM.Control.verbose false (or -Ccm.verbose=false) can be used
903 :     to suppress them.

916 :     Tag: release-110.60
917 :     Description:
918 :    
919 :     New working release (110.60). NEW BOOTFILES!
920 :    
921 :     This is the first subversion-hosted release. There are also changes
922 :     to the directory layout. Here is a table:
923 :    
924 :     (All pathnames are relative to the SML/NJ "root" directory.)
925 :    
926 :     config -> config
927 :    
928 :     src/cm -> base/cm
929 :     src/compiler -> base/compiler
930 :     src/runtime -> base/runtime
931 :     src/system -> base/system
932 :    
933 :     src/cm/pgraph -> pgraph
934 :    
935 :     src/READMES -> base/READMES
936 :     src/$notefile -> base/NOTES/$notefile
937 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
938 :     MACOSXINSTALL WININSTALL
939 :    
940 :     src/smlnj-lib -> smlnj-lib
941 :     src/MLRISC -> MLRISC
942 :     ckit -> ckit
943 :     src/cml -> cml
944 :     src/eXene -> eXene
945 :     src/heap2asm -> heap2asm
946 :     src/lexgen -> lexgen
947 :     src/ml-burg -> ml-burg
948 :     src/ml-lex -> ml-lex
949 :     src/ml-yacc -> ml-yacc
950 :     src/ml-nlffi-lib -> nlffi/lib
951 :     src/ml-nlffigen -> nlffi/gen
952 :     src/smlnj-c -> smlnj-c
953 :     src/tools/TraceDebugProf -> trace-debug-profile
954 :    
955 :     In addition, there is also a new
956 :    
957 :     ml-lpt
958 :    
959 :     directory containing two new program generator tools: ml-ulex and
960 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
961 :     LL(k) parser generator). These tools are currently "beta-quality"
962 :    
963 :     The latest versios of the sources can now be obtained anonymously
964 :     via subversion. For this, it is useful to first check out
965 :    
966 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
967 :    
968 :     and put the resulting directory on your shell's PATH. This provides
969 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
970 :     and refresh-all.sh.
971 :    
972 :     To create a freshly checked-out copy of the sources, do
973 :    
974 :     checkout-all.sh [dir]
975 :    
976 :     where dir is the optional SML/NJ root directory (default is ".").
977 :    
978 :     This creates the above directory layout. Each subdirectory of
979 :     the root is under individual subversion control. The stat-all.sh
980 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
981 :     each of these subtrees.
982 :

985 : blume 2155 Date: 2006/11/02 12:20:00 CST
986 :     Description:
987 :    
988 :     Reorganized directory layout.
989 :    
990 :     This is a temporary solution, more reorganization is to come.
991 :    
992 :     The basic idea is to have a number of toplevel trees, each corresponding
993 :     to a well-defined part of the overall system. Each part can be
994 :     maintained individually, even in separate source repositories,
995 :     although currently we still serve everything out of the main
996 :     smlnj-gforge tree.
997 :    
998 :     Installer and and scripts have been updated to reflect the new
999 :     layout. The installer (base/src/system/smlnj/installer) is now
1000 :     "scriptable" to avoid burning too much knowledge about the
1001 :     layout into SML source code. The main script used by the installer
1002 :     is in config/actions.
1003 :    
1004 :     The main change is that many of the subdirectories of what used to
1005 :     be known as "src" have moved to the toplevel. The "src" directory
1006 :     itself has moved down into a subtree called "base". (We may eventually
1007 :     get rid of the extra level of indirection represented by "src".)
1008 :    
1009 :     The layout is now as follows:
1010 :    
1011 :     toplevel tree name | default repository
1012 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1013 :     -------------------+----------------------------------------------------
1014 :     config | $gf/config/trunk
1015 :     |
1016 :     base | $gf/sml/trunk
1017 :     |
1018 :     smlnj-lib | $gf/smlnj-lib/trunk
1019 :     MLRISC | $gf/MLRISC/trunk
1020 :     |
1021 :     ml-yacc | $gf/ml-yacc/trunk
1022 :     ml-lex | $gf/ml-lex/trunk
1023 :     ml-burg | $gf/ml-burg/trunk
1024 :     lexgen | $gf/lexgen/trunk
1025 :     heap2asm | $gf/heap2asm/trunk
1026 :     |
1027 :     cml | $gf/cml/trunk
1028 :     eXene | $gf/eXene/trunk
1029 :     ckit | $gf/ckit/trunk
1030 :     nlffi | $gf/nlffi/trunk
1031 :     |
1032 :     smlnj-c | $gf/smlnj-c/trunk
1033 :    
1034 :     In $gf/admin there are a few useful shell scripts for checking out
1035 :     and maintaining the entire collection of trees:
1036 :    
1037 :     admin/checkout-all.sh [dir]
1038 :     -- optionally creates dir and checks out all trees from their
1039 :     default repositories; if dir is missing, checkout into .
1040 :     admin/refresh-all.sh [dir]
1041 :     -- looks at all trees (from the above list) in dir (default: .)
1042 :     and runs "svn update" if the tree exists and is under
1043 :     subversion control;
1044 :     non-existing or non-subversion trees are skipped
1045 :     admin/stat-all.sh [dir]
1046 :     -- like refresh-all.sh, but runs "svn stat" instead

1194 :     Hooked code for Darwin-specific Intel ABI into main compiler.
1195 :     (This is a temporary solution which relies on the fact that the

1226 :     Description:
1227 :    
1228 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1229 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1230 : blume 2155 at the time when config/preloads is processed, the library has to
1231 : mblume 1878 be referred to by another name. In 110.57 this would be
1232 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1233 :     to be valid as well.)

1288 :     Tag: blume-22051115-versiontool
1289 :     Description:
1290 :    
1291 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1292 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1293 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1294 :     it. Instead, it has the status of "user code", so it should use
1295 :     $/basis.cm to refer to the Basis library. (At least that's true for
1296 :     the purpose of bootstrapping the previous change. In the future it
1297 :     might make sense to have versiontool.cm refer to
1298 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1299 :     compiler itself uses.)
1300 :    
1301 :     Also patched src/system/testml to have it activate those extra anchor
1302 :     bindings in config/extrapathconfig.

1307 :     Tag: blume-22051115-libraries
1308 :     Description:
1309 :    
1310 :     This change affects the way the following libraries are tied into
1311 :     the system:
1312 :    
1313 :     $/basis.cm
1314 :     $/smlnj-lib.cm
1315 :     $/pp-lib.cm
1316 :     $/controls-lib.cm
1317 :     $/html-lib.cm
1318 :     $/ml-yacc-lib.cm
1319 :    
1320 :     These libraries are now internally (as seen from the source code
1321 :     of the implementation itself) known by the following names:
1322 :    
1323 :     $smlnj/basis/basis.cm
1324 :     $smlnj/smlnj-lib/smlnj-lib.cm
1325 :     $smlnj/smlnj-lib/pp-lib.cm
1326 :     $smlnj/smlnj-lib/controls-lib.cm
1327 :     $smlnj/smlnj-lib/html-lib.cm
1328 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1329 :    
1330 :     This makes it possible to work with code that requires different
1331 :     versions of these libraries, and which refers to these libraries using
1332 :     their "default" names (i.e., the first set of names above). In other
1333 :     words, one can un-define or re-define those default names without
1334 :     compromising the proper functioning of the compiler itself.
1335 :    
1336 :     A similar procedure had already been performed for several of the
1337 :     MLRISC libraries that are linked into the compiler. I did some
1338 :     cleanup on this code.
1339 :    
1340 :     A new file in the config directory (named extrapathconfig) is
1341 :     responsible for setting up path anchors that the compiler itself does
1342 :     not need, but that are typically required by user code.

1521 :     Tag: blume-20050516-redump-heap
1522 :     Description:
1523 :    
1524 :     Added mechanism for re-creating a heap file for the interactive system
1525 :     after configuration variables have been changed.
1526 :    
1527 :     CM.redump_heap : string -> unit
1528 :    
1529 :     This is much like SMLofNJ.exportML, but starting from the resulting
1530 : blume 2155 heap does not return to the caller of CM.redump_heap but
1531 : mblume 1792 restarts the interactive system from scratch. The original call of
1532 :     CM.redump_heap does not return but ends the interactive session.
1533 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1534 :    
1535 :     Internally, redump_heap winds the dynamic execution context back to
1536 :     the point where the original heap image was created and re-executes
1537 :     the heap image generation code in the boot code.

1653 :     Tag: blume-20050114-heap2exec
1654 :     Description:
1655 :    
1656 :     Implemented new (but still experimental) heap2exec facility. This is
1657 :     tested under Mac OS X and should work under Linux (will test shortly).
1658 :     It will probably also work on the Sparc (will test some time later).
1659 :    
1660 :     - removed old "HACKED_STANDALONE" hack from runtime
1661 :    
1662 :     To be able to test this, uncomment the request for "heap2asm" in
1663 :     config/targets prior to installation. (Notice that this is different
1664 :     from "heap2exec" mentioned below. Not a typo.)
1665 :    
1666 :     To perform an actual test, run the command
1667 :    
1668 :     $ bin/heap2exec heapfile execfile
1669 :    
1670 :     (You can put heap2exec on your shell's path.)
1671 :    
1672 :     For example, run
1673 :    
1674 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1675 :    
1676 :     This will create a standalone executable called "mly" which you can
1677 :     then invoke directly as a command.

1703 :     data structure access seems to work.)
1704 :    
1705 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1706 :     (On the Mac, it is big-endian. And that's currently our only
1707 :     PPC platform.)

1822 :     Tag: blume-20041124-position
1823 :     Description:
1824 :    
1825 :     The compiler can now be compiled in a mode that makes structure Position
1826 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1827 :     for the time being.
1828 :    
1829 :     To enable 64-bit positions, use the following procedure:
1830 :    
1831 :     1. Start sml
1832 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1833 :     3. Type
1834 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1835 :     4. Run CMB.make() as usual.
1836 :    
1837 :     This is barely tested. The only test so far was a little SML program
1838 :     counting the number of characters in an 8-gigabyte file by
1839 :     reading it character-by-character. That test was successful.
1840 :    
1841 :     In support of 64-bit positions, a number of new functions have been
1842 :     added to the runtime system.

1886 :     The date string is generated at bootstrap time (during makeml).
1887 :    
1888 :     - In a previous commit, fixed a minor issue with how polyequal is being
1889 :     translated. In particular, the code now "looks through" abstractions.
1890 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1891 :     more efficient code. Important examples for where this matters are
1892 :     the new int64 and word64 types.

1907 :     Description:
1908 :    
1909 :     All the pieces of Word64 are now there, with the exception of the
1910 :     conversions from and to LargeWord. (Eventually these need to be identities,
1911 :     but for the time being they don't even make sense because LargeWord is
1912 :     32-bit wide.)
1913 :    
1914 :     Also started to add similar support for Int64, but major pieces of that
1915 :     are still missing.

1920 :     Tag: blume-20041111-word64
1921 :     Description:
1922 :    
1923 :     Structure Word64 is now (almost) complete, word literals and patterns
1924 :     seem to work. There are a few odd pieces missing. In particular,
1925 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1926 :     at the moment.
1927 :    
1928 :     Making Word64 official would mean that LargeWord becomes Word64. But
1929 :     this requires extreme care because most word-word conversions have to
1930 :     go through LargeWord, so making a mistake means loss of efficiency or
1931 :     worse. Eventually there will be a solution similar to (but actually
1932 :     simpler than) what I did with IntInf.

1967 :     - Made corresponding changes to config/install.sh and config/unpack.
1968 :     - Default contents of config/srcarchiveurl uses $VERSION and
1969 :     normally does not have to be edited to reflect a version change.
1970 :    
1971 :     (As a result, a version change can be done by just editing
1972 :     config/version, the rest is now automatic.)

2012 :     Tag: blume-20041020-standalone-backtrace
2013 :     Description:
2014 :    
2015 :     Added a mechanism for getting back-trace information from standalone
2016 :     programs. Here is how it works:
2017 :    
2018 :     1. The part of the program from which you want to get backtrace
2019 :     information (usually the whole program) should be wrapped with
2020 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
2021 :     main program could be modified from something like
2022 :    
2023 :     fun main (pgm, args) = ...
2024 :    
2025 :     to
2026 :    
2027 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2028 :    
2029 :     2. To be able to access BackTrace.monitor, you have to add
2030 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
2031 :     main function.
2032 :    
2033 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2034 :     CM might have created in the past for your project).
2035 :    
2036 :     4. Build the system using this command line:
2037 :    
2038 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2039 :     myprog.cm MyProg.main myprog
2040 :    
2041 :     instead of the usual
2042 :    
2043 :     ml-build myprog.cm MyProg.main myprog
2044 :    
2045 :     I changed a library name:
2046 :    
2047 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2048 :    
2049 :     New libraries:
2050 :    
2051 :     $smlnj-tdp/back-trace.cm
2052 :     -- when loaded causes the back-trace plugin to be installed
2053 :     $smlnj-tdp/coverage.cm
2054 :     -- when loaded causes the coverage plugin to be installed

2070 :     Description:
2071 :    
2072 :     * Test coverage tool added!
2073 :     * Further reorganization of tracing-, debugging-, and profiling support:
2074 :    
2075 :     - moved original BTImp -- now called BackTrace -- into a separate
2076 :     library called $/trace-debug-profile.cm
2077 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2078 :     - only the instrumentation mechanism is now left in the compiler proper
2079 :     - BackTrace module is a plugin which is NOT plugged in by default
2080 :     - Coverage module is another such plugin
2081 :    
2082 :     To get the benefits of any of these plugin modules, the code in
2083 :     question must be compiled with tdp instrumentation turned on. This
2084 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2085 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2086 :    
2087 :     Plugins are selected at link time. (Pre-compiled instrumented code
2088 :     can be re-loaded with different plugins in effect.) When an
2089 :     instrumented module is linked, whatever plugins are at that time
2090 :     enabled will come into effect for that module.
2091 :    
2092 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2093 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2094 :     To enable the coverage plugin, load the same library and invoke
2095 :     Coverage.install().
2096 :    
2097 :     Back-traces are generated automatically on uncaught exceptions and
2098 :     when the code in question explicitly invokes BackTrace.trigger().
2099 :    
2100 :     Coverage (and execution frequency-) information must be queried
2101 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2154 :     "*", and "-" as ordinary identifiers rather than keywords.
2155 :    
2156 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool
2157 :     is supposed to accept a tool argument called "source", but this did
2158 :     not work because of the clash with the keyword.

2210 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2211 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2212 :     Also, loading the versiontool does not work when rebuilding the system
2213 :     because CM is not properly initialized at that time.

2218 :     Tag: blume-20040929-autoversion
2219 :     Description:
2220 :    
2221 :     Implemented some CM magic to have
2222 :     file src/compiler/TopLevel/main/version.sml
2223 :     generated automagically.
2224 :     The version is taken from two files: config/version and config/release.
2225 :     The first is expected to contain a two-part version number such as 110.49.
2226 :     The second should contain a single number, but it may be missing.
2227 :    
2228 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2229 :     time the version tool is loaded (which is the first time you say CMB.make),
2230 :     then the tool will increment the value stored in config/release every
2231 :     time CMB.make is invoked.
2232 :    
2233 :     The binfile format is now insensitive to anything beyond the first
2234 :     two components of a version number, so bumping the release does not render
2235 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2236 :     during development without invalidating existing binfiles.
2237 :    
2238 :     In any case, every CMB.make updates the date information in version.sml.
2239 :     (This is the date that is printed in the banner.)

2252 :     Tag: blume-20040927-controls
2253 :     Description:
2254 :    
2255 :     Added two pieces of functionality to the Controls interface:
2256 :    
2257 :     1. val save'restore: 'a control -> unit -> unit
2258 :    
2259 :     grabs the current value of the control in stage 1 and restores it
2260 :     in stage 2.
2261 :    
2262 :     2. val set' : 'a control * 'a -> unit -> unit
2263 :    
2264 :     stores the given value into the control in stage 2 (i.e., delayed)
2265 :     but does all error checking in stage 1.
2266 :     (This is for string controls that need to do parse their argument --
2267 :     something that might fail. In some cases, notably in CM, one
2268 :     already knows the intended argument but wants to delay the actual
2269 :     assignment until a time when error recovery would be more difficult.)
2270 :    
2271 :     Changed the handling of controls in tool arguments to classes "sml" and
2272 :     "lazysml":
2273 :     - use Controls.save'restore as a more robust way of restoring the
2274 :     old value (in particular: without having to re-parse the string)
2275 :     - use controls to handle the "overload" keyword in the init group
2276 :     (I believe this change actually fixes a long-standing obscure bug.)

2281 :     Tag: blume-20040927-lazysml
2282 :     Description:
2283 :    
2284 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2285 :     difference to "sml" is that compilation is done with Control.lazysml
2286 :     set to true. A source of class "lazysml" is automatically recognized
2287 :     by a file name suffix of ".lml".
2288 :    
2289 :     In addition to the above feature, the original class "sml" now also
2290 :     supports a tool argument "lazy" which has the same effect. As a
2291 :     result, the following three lines are equivalent:
2292 :    
2293 :     foo.sml : lazysml
2294 :     foo.sml : sml (lazy)
2295 :     foo.sml (lazy)
2296 :    
2297 :     The setting goes into effect both during parsing and during
2298 :     compilation. The original setting is restored right after parsing and
2299 :     after compilation, respectively.
2300 :    
2301 :     In addition to all the above, there is also a general mechanism to set
2302 :     ANY of the "controls" that are available at the command line via
2303 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2304 :     apply as well. (In fact, "lazy" is implemented as a special case of
2305 :     the general mechanism.)
2306 :    
2307 :     The .cm file syntax uses a new keyword tool argument called "with".
2308 :     There are several ways of indicating the desired settings:
2309 :    
2310 :     foo.sml (with:parser.quotations=true)
2311 :     foo.sml (with:(name:parser.quotations value:true))
2312 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2313 :     foo.sml (with:(name1=value1 name2=value2 ...))
2314 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2315 :    
2316 :     etc.
2317 :    
2318 :     Another possible abbreviation is to leave out the =v or value:v part
2319 :     if the name refers to a boolean control (in which case the value is
2320 :     taken to be true). Thus, one could get lazy sml also by saying:
2321 :    
2322 :     foo.sml (with:parser.lazy-keyword=true)
2323 :     foo.sml (with:parser.lazy-keyword)
2324 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2325 :     foo.sml (with:(name:parser.lazy-keyword))

2625 :     (for PPC version where parameter area is pre-allocated)
2626 :     - added ccall_maxargspace to machspec (to implement the above)
2627 :     - made "make" commend in CM's "make" tool configurable
2628 :     - added option (default: on) for passing the name of the SML/NJ's "bin"
2629 :     directory to "make"; the call looks like this:
2630 :    
2631 :     make <options> SMLNJ_BINDIR=<dir> <target>

2677 :     Description:
2678 :    
2679 :     Changed the interface of structures Timer and Unix to match the most
2680 :     recent Basis spec.
2681 :    
2682 :     In the case of Unix there still seems to be an open/weird issue:
2683 :    
2684 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2685 :     fresh streams whenever they are called -- as opposed to have them
2686 :     return the same stream every time. This design is supposed to
2687 :     prevent space leaks caused by proc values hanging on to streams.
2688 :    
2689 :     The reap function, on the other hand, is supposed to close the
2690 :     streams. This cannot be done without having a handle on the
2691 :     stream in proc after all...
2692 :    
2693 :     I took the liberty to implement the following stopgap solution:
2694 :    
2695 :     The proc value hangs on to the most recently created stream(s).
2696 :     Reap closes those. If either or both of the two streams hadn't
2697 :     been created at all yet, then reap will close the corresponding
2698 :     file descriptors directly.
2699 :    
2700 :     PS: I don't understand the original space leak argument anymore. If
2701 :     a proc hangs on to the imperative stream, then I/O operations on those
2702 :     will advance the state of the cached stream and avoid the space leak.

2715 :     Tag: blume-20040525-group-owner
2716 :     Description:
2717 :    
2718 :     CM now ignores (but still accepts) the "owner" information in group
2719 :     descriptions. The owner of a group is its next enclosing
2720 :     library. Each group must have a unique owner. (There is a virtual
2721 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2722 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2723 :     and CM would check that such a declaration is correct. The new scheme
2724 :     is to have CM check that for each group there is precisely one owning
2725 :     library.
2726 :    
2727 :     The advantage of the new scheme is that the programmer no longer needs
2728 :     to maintain the somewhat annoying owner information. The downside is
2729 :     that CM cannot enforce the ownership rule across multiple runs of
2730 :     CM.make. Fortunately, enclosing the same group in two different
2731 :     libraries A and B which are not part of the same program does not
2732 :     cause real problems.

2751 :     Description:
2752 :    
2753 :     Arranged for ml-build to clean up after itself a little bit better.
2754 :     The script generates a temporary SML source file and compiles it using
2755 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
2756 :     gets rid of those at the end, so they don't accumulate under .cm.
2757 :    
2758 :     This required a minor change to install.sh because the name of the

2778 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
2779 :     for the voluminous patch!
2780 :    
2781 :     (I have not tested this patch under win32 yet.)
2782 :    
2783 : mblume 1490 Here is David's e-mail:
2784 :    
2785 :     Hi,
2786 :    
2787 :     Attached to this email you find a diff against sml/nj 110.45
2788 :     that will enable socket support under Windows.
2789 :    
2790 :     To apply the patch (using unix or cygwin)
2791 :     1) gunzip runtime.diff.gz
2792 :     2) "cd" into "src/runtime" in the source tree of a fresh
2793 :     110.45 installation.
2794 :     3) patch -p 1 < [your/path/to]runtime.diff
2795 :    
2796 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2797 :     I only ran a few tests for basic socket client functionality
2798 :     (which worked fine). Especially the functions that use ioctl
2799 : mblume 1490 are not tested at all and might not work (see below).
2800 :    
2801 :     I implemented this since we want to move to a newer version of sml/nj
2802 :     but need socket support in order to use it. This is the first time I
2803 :     even had a look at the sml/nj source, so please review my changes
2804 :     before making this part of the distribution! Here are a few issues
2805 : blume 2155 that I think might be better for someone to solve who is more
2806 : mblume 1490 familiar with the sml/nj source (and socket programming):
2807 :    
2808 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2809 :     exception since I could not figure out what the windows equivalent
2810 :     of these functions is
2811 :    
2812 :     - In sockets-osdep.h there are a some #include statements that are
2813 :     only used in a few files that include sockets-osdep.h
2814 :    
2815 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2816 :     does not process its return value since I don't know how to
2817 :     report an error upwards.
2818 :    
2819 :     - It would probably be good to have a call to WSACleanup() when
2820 : blume 2155 the library is unloaded (if there is such a possibility).
2821 : mblume 1490 Otherwise I think Windows will take care of this automatically
2822 :     when the process finishes.
2823 :    
2824 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2825 :     no idea if that is actually the proper replacement on Windows.
2826 :    
2827 :     - All these issues are marked in the code by "FIXME" comments.
2828 :    
2829 : blume 2155 We use sml/nj extensively in our products and are quite happy
2830 :     with it. I hope this contribution will help you.
2831 : mblume 1490
2832 :     Keep up the good work!

2909 :     Description:
2910 :    
2911 :     Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
2912 :     of SML/NJ. The problem is that
2913 :    
2914 :     lib = dlopen(NULL, ...)
2915 :     f = dlsym(lib, "malloc");
2916 :    
2917 : blume 2155 does not work on Windows unless we explicitly export symbols
2918 :     such as 'malloc' during linking. We fixed this by explicitly
2919 : allenleung 1468 exporting the required symbols with the magic gcc incantation:
2920 :    
2921 :     -Wl,--export-all cygwin.def
2922 :    
2923 :     where cygwin.def is a file containing all the symbols that
2924 : blume 2155 we wish to export.
2925 : allenleung 1468
2926 : blume 2155 I suspect this is a Windows problem and we'll have to
2927 :     do the same (somehow with windows compilers) when
2928 : allenleung 1468 we build the native win32 version with the system
2929 : blume 2155 calls LoadLibrary/GetProcAddress.

3000 :     (The mechanism was broken and could not be fixed easily. Moreover,
3001 :     there does not seem to be any reason not to move all libraries into
3002 :     lib during installation. I originally implemented this directive as a
3003 :     backward-compatibility feature when I first introduced the new CM.
3004 :     Now that things have been stable for a long time and going back to the
3005 :     old CM is not an option, there is no reason to keep it around.)

3054 :     Tag: blume-20030926-ppautoload
3055 :     Description:
3056 :    
3057 :     I modified the read-eval-print loop so that the autoloader gets
3058 :     invoked whenever the prettyprinter tries to look up a symbol that
3059 :     is not currently defined in the toplevel environment but which
3060 :     appears in CM's autoload registry. As a result, we see far fewer of
3061 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3062 :    
3063 :     In addition to this I tried to clean up some pieces of the Basis
3064 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3065 :     instances of these ?.Foo.Bar.xxx names from being printed.
3066 :    
3067 :     The mechanism that picks names for types still needs some work, though.
3068 :     (Right now it seems that if there is a type A.t which is defined to
3069 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3070 :     "?.B.u" although the perhaps more sensible solution would be to use
3071 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3072 :     a chain of DEFtycs not farther than there are corresponding toplevel
3073 :     names in the current environment.)

3079 :     Description:
3080 :    
3081 :     Another installer tweak: All the ML code for the installer is now
3082 :     compiled during CMB.make and put into a little library called
3083 :     $smlnj/installer.cm. The installation then simply invokes
3084 :    
3085 :     sml -m $smlnj/installer.cm
3086 :    
3087 :     and everything happens automagically.
3088 :    
3089 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3090 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3091 :     and BINDIR.
3092 :    
3093 :     The new scheme guarantees that the ML code responsible for the installation
3094 :     is in sync with the APIs of the main system. Also, the installer is
3095 :     somewhat faster because the installer script is precompiled.

3107 :     structure.

3112 :     Tag: blume-20030924-sockets
3113 :     Description:
3114 :    
3115 :     1. Fixed SOCKET API and implementation to match Basis spec.
3116 :     This required changing the internal representation of sockets to one
3117 :     that remembers (for each socket file descriptor) whether it is currently
3118 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3119 :     call is made only if the state actually needs to change).
3120 :    
3121 :     2. OS-specific details of sockets were moved into separate files, thus
3122 :     making it possible to unify the bulk of the socket implementations
3123 :     between Unix and Win32.
3124 :    
3125 :     3. CML's socket API changed accordingly.
3126 :     (Note that we need to remove non-blocking functions from this API
3127 :     since they are redundant in the case of CML!)
3128 :    
3129 :     4. CML's socket implementation now makes use of non-blocking functions
3130 :     provided by Basis, thus removing all OS-dependent code from this part
3131 :     of CML.
3132 :    
3133 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3246 :     Description:
3247 :    
3248 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3249 :     Modified config/install.bat to take advantage of it. Also modified
3250 :     config/install.sh (and called it config/new-install.sh) to take advantage
3251 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3252 :     independent.)
3253 :    
3254 :     The installer can now install everything under Win32
3255 :     as well as under *nix as long as it compiles.
3256 :    
3257 :     Other changes:
3258 :    
3259 :     - made CML compile again under Win32
3260 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3261 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3262 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3263 :     same as type int; under Win32 it isn't
3264 :     - fixed some slice-related problems in the win32-specific parts of CML
3265 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3266 :     (under Win32, the volume name is case-insensitive, and the

3284 : mblume 1350 Description:
3285 :    
3286 :     1. Changed interface to vectors and arrays in Basis to match
3287 :     (draft) Basis spec.
3288 :     2. Added signatures and implementations of slices according to
3289 :     Basis spec.
3290 :     3. Edited source code throughout the system to make it compile again
3291 :     under 1. and 2. (In some cases code had to be added to have it
3292 :     match the new signatures.)
3293 :     4. MLRISC should be backward-compatible: the copies of the originals
3294 :     of files that needed to change under 3. were retained, the .cm files
3295 :     check the compiler version number and use old versions when
3296 :     appropriate.
3297 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3298 :     dirstream -> string option (in accordance with Basis spec).
3299 :     6. When generating code that counts lines, ml-lex used function
3300 :     CharVector.foldli, taking advantage of its old interface.
3301 :     This has been replaced with the corresponding code from
3302 :     CharVectorSlice. (html-lex must be re-lexed!)
3303 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3304 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3305 :     8. Removed temporary additions (fromInternal, toInternal) from the
3306 :     (now obsolete) IntInf in smlnj-lib/Util.
3307 :     9. Cleaned up structure Byte.
3308 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3309 :     Cleaned/corrected implementation of Date.
3310 :     (Still need to check for correctness; implement better canonicalizeDate.)
3311 :     11. Added "scan" to signature IEEE_REAL.
3312 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3313 :     mod and rem when second operand is 2 (for parity checks).]
3314 :     13. Changed representation of type Time.time, using a single IntInf.int
3315 :     value counting microseconds. This considerably simplified the
3316 :     implementation of structure Time. We now support negative time
3317 :     values; scan and fromString handle signs.
3318 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3319 :     ArraySlice).

3324 :     Tag: blume-20030828-intinf
3325 :     Description:
3326 :    
3327 :     This is a major update which comes with a version number bump
3328 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3329 :     and an implementation of IntInf in the Basis.
3330 :    
3331 :     There are a fairly large number of related changes and updates throughout
3332 :     the system:
3333 :    
3334 :     Basis:
3335 :     - Implemented IntInf.
3336 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3337 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3338 : mblume 1347 - Added FixedInt as a synonym for Int32.
3339 :    
3340 :     compiler:
3341 :     * Added support for a built-in intinf type.
3342 :     - literals
3343 :     - pattern matching
3344 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3345 :     - overloading on literals and operations
3346 :    
3347 :     This required adding a primitive type intinf, some additional
3348 :     primops, and implementations for several non-trivial intinf
3349 :     operations in Core. (The intinf type is completely abstract
3350 :     to the compiler; all operations get delegated back to the Core.)
3351 :    
3352 :     * Intinf equality is handled by polyequal. However, the compiler
3353 :     does not print its usual warning in this case (since polyequal
3354 :     is the right thing to do there).
3355 :    
3356 :     * Improved the organization of structure InlineT.
3357 :    
3358 :     * A word about conversion primops:
3359 :     If conversions involving intinf do not cancel out during
3360 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3361 : mblume 1347 Since all core access must be resolved already during the FLINT
3362 :     translate phase, it would be too late a the time of CPS contract
3363 : mblume 1348 to add new Core calls. For this reason, conversion primops
3364 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3365 :     they are supposed to convert, and 2. the Core function that
3366 :     can help with this conversion if necessary. If CPS contract
3367 : mblume 1348 eliminates a primop, then the associated Core function becomes
3368 :     dead and goes away. Intinf conversion primops that do not get
3369 :     eliminated by CPS contract get rewritten into calls of their
3370 :     core functions by a separate, new phase.
3371 : mblume 1347
3372 :     interactive system:
3373 :     - Control.Print.intinfDepth controls max length of intinf constants
3374 :     being printed. (Analogous to Control.Print.stringDepth.)
3375 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3376 :     duplicates; replaced some of the code with code that makes better
3377 :     use of library functionality.
3378 :    
3379 :     CM:
3380 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3381 :     are no longer silent.
3382 :    
3383 :     CKIT:
3384 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3385 :     in favor of LargeInt -- which is now the same as IntInf.
3386 :     CKIT-knowledgable people should check whether this is what's
3387 :     intended and otherwise change things back to using Int32 or
3388 :     FixedInt.
3389 :    
3390 :     Throughout the code:
3391 : mblume 1348 Started using IntInf.int literals and built-in operations
3392 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3411 :     Tag: blume-20030811-windows
3412 :     Description:
3413 :    
3414 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3415 :    
3416 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3417 :    
3418 :     This patch restores SML/NJ's ability to run under win32. There are a
3419 :     number of changes, including fixes for several bugs that had gone
3420 :     unnoticed until now:
3421 :    
3422 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3423 :     trying to run the win32 version from within cygwin.)
3424 :    
3425 :     - There are a number of simple .bat scripts that substitute for their
3426 :     corresponding Unix shell-scripts. (See below.)
3427 :    
3428 :     - The internals of ml-build have been modified slightly. The main
3429 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3430 :     using OS.Process.system, the ML process delegates this task back
3431 :     to the script. Otherwise problems arise in mixed environments such
3432 :     as Cygwin where scripts look and work like Unix scripts, but
3433 :     where OS.Process.system cannot run them.
3434 :    
3435 :     - In CM, the srcpath pickler used native pathname syntax -- which
3436 :     is incorrect in the case of cross-compilation. The new pickle format
3437 :     is independent of platform-specific naming conventions.
3438 :    
3439 :     - Path configuration files (such as lib/pathconfig) can now choose
3440 :     between native and standard syntax. Placing a line of the form
3441 :    
3442 :     standard!
3443 :    
3444 :     into the file causes all subsequent paths to be interpreted using
3445 :     CM standard pathname syntax (= Unix conventions); a line
3446 :    
3447 :     native!
3448 :    
3449 :     switches back to native style. This was needed so that
3450 :     path config files can be written portably, see src/system/pathconfig.
3451 :    
3452 :     - Runtime system:
3453 :    
3454 :     - win32-filesys.c: get_file_time and set_file_time now
3455 :     access modification time, not creation time.
3456 :    
3457 :     - I/O code made aware of new array representation.
3458 :    
3459 :     - Bug fixes in X86.prim.masm.
3460 :    
3461 :     - src/system/makeml made aware of win32. (For use under cygwin
3462 :     and other Unix-environments for windows.)
3463 :    
3464 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3465 :     which caused BinIO.inputAll to fail consistently.
3466 :    
3467 :     .bat scripts:
3468 :    
3469 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3470 :    
3471 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3472 :     applications (sml, ml-yacc, ml-lex).
3473 :     - ml-build.bat: analogous to ml-build.
3474 :     - config\install.bat: Analogous to config/install.sh. This requires
3475 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3476 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3477 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3478 :     and the bootfile hierarchy must have been unpacked under
3479 :     sml.boot.x86-win32.
3480 :     The script is very primitive and does a poor job at error checking.
3481 :     It only installs the base system, ml-lex, and ml-yacc. No other
3482 :     libraries are being installed (i.e., you get only those that
3483 :     are part of the compiler.)
3484 :     - link-sml.bat: analogous to .link-sml, but not currently used
3485 :    
3486 :     Unrelated bug fixes:
3487 :    
3488 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3489 :     types.
3490 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3491 :     otherwise.)

3515 :     Description:
3516 :    
3517 :     Two changes:
3518 :    
3519 :     1. Added a flag for controlling whether non-exhaustive bindings will
3520 :     be treated as errors (default is false).
3521 :     2. Cleaned up the *entire* source tree so that CMB.make goes through

3528 :     Description:
3529 :    
3530 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3531 :    
3532 :     This mainly affects the quality of error messages. However, some
3533 :     of the code is now more straightforward than before. (Treatment of
3534 :     the above four constructs in translate.sml is much simpler than
3535 :     the "macro-expansion" that was going on before. Plus, the mach-
3536 :     compiler no longer gets invoked just to be able to compile an
3537 :     if-expression.)
3538 :    
3539 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3540 :     interactive loop.

3558 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3559 :

3694 :     Description:
3695 :    
3696 :     Fixed a bug in translation of INLMAX (and INLMIN) for the floating-point
3697 :     case. (The sense of the isNaN test was reversed -- which made min and
3698 :     max always return their first argument.)

3714 :     I back-ported my implementation of IEEEReal.fromString from the
3715 :     idlbasis-devel branch so that we can test it.
3716 :    
3717 :     Another small change is that ppDec tries to give more information
3718 :     than just "<sig>" in the case of functors. However, this code is
3719 :     broken in some mysterious way if the functor's body's signature
3720 :     has not been declared by ascription but gets inferred from the
3721 :     implementation. This needs fixing...

3787 :     - Used Controls facility to define MLRISC controls (as opposed to
3788 :     registering MLRISC control ref cells with Controls after the fact)
3789 :     - Fixed messed-up controls priorities.
3790 :    
3791 :     * Removed again all the stuff from config/preloads that one wouldn't
3792 :     be able to preload at the time the initial heap image is built.
3793 :     (Many libraries, e.g., CML, do not exist yet at this time. The
3794 :     only libraries that can be preloaded via config/preloads are those
3795 :     that come bundled with the bootfiles.)

3820 :     Description:
3821 :    
3822 :     0. John Reppy made several modifications to the SML/NJ library.
3823 :     In particular, there is a shiny new controls-lib.cm.
3824 :    
3825 :     1. Pushed new controls interface through compiler so that everything
3826 :     compiles again.
3827 :    
3828 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3829 :     SML/NJ library (so that CML compiles again).
3830 :    
3831 :     3. Modified init scripts because XXX_DEFAULT environment variables
3832 :     are no longer with us. (Boot-time initialization is now done
3833 :     using the same environment variables that are also used for
3834 :     startup-time initialization of controls.)

3840 :     Description:
3841 :    
3842 :     All pseudo-ops emitted before the first segment declaration
3843 :     such as TEXT, DATA, and BSS directives are assumed to be global
3844 :     declarations and are emitted first in the assembly file. This is
3845 :     useful in a number of situations where one has pseudo-ops that are not
3846 :     specific to any segment, and also works around the constraint that one
3847 :     cannot have client pseudo-ops in the TEXT segment.
3848 :    
3849 :     Because no segment is associated with these declarations it is
3850 :     an error to allocate any space or objects before the first segment
3851 :     directive and an exception will be raised. However, we cannot make
3852 :     this check for client pseudo-ops.
3853 :    
3854 :     These top level declarations are a field in the CFG graph_info.
3855 :     In theory you can continue to add to this field after the CFG has been
3856 :     built -- provided you know what you are doing;-)

3862 :     Description:
3863 :    
3864 :     A few minor bugfixes:
3865 :    
3866 :     - Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
3867 :     (Bogus printouts for redefined bindings still occur. Compiler
3868 :     bug should no longer occur now. We need to redo the prettyprinter
3869 :     from scratch.)
3870 :    
3871 :     - CM pathname printer now also adds escape sequences for ( and )
3872 :    
3873 :     - commend and docu fixes for ml-nlffi

3878 :     Tag: blume-20020510-erg-textio
3879 :     Description:
3880 :    
3881 :     Applied the following bugfix provided by Emden Gansner:
3882 :    
3883 :     Output is corrupted when outputSubstr is used rather than output.
3884 :    
3885 : blume 2155 The problem occurs when a substring
3886 : blume 1189
3887 :     ss = (s, dataStart, dataLen)
3888 :    
3889 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3890 :     avail bytes of s, starting at index dataStart, are copied into the
3891 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3892 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3893 :     starting this copy at index dataStart+avail in s, the current code
3894 : blume 1189 starts the copy at index avail.
3895 :    
3896 :     Fix:
3897 :     In text-io-fn.sml, change line 695 from
3898 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3899 : blume 2155 to
3900 : blume 1189 val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

3916 :     Description:
3917 :    
3918 :     Added full support for div/mod/rem/quot on the x86, using the machine
3919 :     instruction's two results (without clumsily recomputing the remainder)
3920 :     directly where appropriate.
3921 :    
3922 :     Some more extensive power-of-two support was added to the x86 instruction
3923 :     selector (avoiding expensive divs, mods, and muls where they can be
3924 :     replaced with cheaper shifts and masks). However, this sort of thing
3925 :     ought to be done earlier, e.g., within the CPS optimizer so that
3926 :     all architectures benefit from it.
3927 :    
3928 :     The compiler compiles to a fixed point, but changes might be somewhat
3929 :     fragile nevertheless. Please, report any strange things that you might
3930 :     see wrt. div/mod/quot/rem...

3936 :     Description:
3937 :    
3938 :     Fixed my broken div/mod logic. Unfortunately, this means that the
3939 :     inline code for div/mod now has one more comparison than before.
3940 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3941 :     The problem was with quotient = 0, because that alone does not tell
3942 :     us which way the rounding went. One then has to look at whether
3943 :     remainder and divisor have the same sign... :(
3944 :

3951 :     Description:
3952 :    
3953 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
3954 :    
3955 :     Primops have changed. This means that the bin/boot-file formats have
3956 :     changed as well.
3957 :    
3958 :     To make sure that there is no confusion, I made a new version.
3959 :    
3960 :    
3961 :     CHANGES:
3962 :    
3963 :     * removed REMT from mltree (remainder should never overflow).
3964 :    
3965 :     * added primops to deal with divisions of all flavors to the frontend
3966 :    
3967 :     * handled these primops all the way through so they map to their respective
3968 :     MLRISC support
3969 :    
3970 :     * used these primops in the implementation of Int, Int32, Word, Word32
3971 :    
3972 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3973 :    
3974 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
3975 :    
3976 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3977 :     floating point
3978 :    
3979 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3980 :     and Real (but Real.abs maps to a separate floating-point-only primop)
3981 :    
3982 :    
3983 :     TODO items:
3984 :    
3985 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
3986 :     instructions because the machine instruction encoder cannot handle
3987 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
3988 :     REM in the first place, and REM is supported by the x86 machine coder.)
3989 :    
3990 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
3991 :     selection phase. (The two can be streamlined because the hardware
3992 :     delivers both quotient and remainder at the same time anyway.)
3993 :    
3994 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
3995 :     (Currently the behavior is inconsistent both across architectures and
3996 :     wrt. the draft Basis spec.)
3997 :    
3998 :     * Word8 should eventually be handled natively, too.
3999 :    
4000 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
4001 :     as if there currently is no execution path that could trigger it in
4002 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
4003 :     hold for things like multiplication and division.)

4008 :     Tag: blume-20020327-mlrisc-divisions
4009 :     Description:
4010 :    
4011 :     Added support for all four division operations (ML's div, mod, quot,
4012 :     and rem) to MLRISC. In the course of doing so, I also rationalized
4013 :     the naming (no more annoying switch-around of DIV and QUOT), by
4014 :     parameterizing the operation by div_rounding_mode (which can be either
4015 :     DIV_TO_ZERO or DIV_TO_NEGINF).
4016 :    
4017 :     The generic MLTreeGen functor takes care of compiling all four
4018 :     operations down to only round-to-zero div.
4019 :    
4020 :     Missing pieces:
4021 :    
4022 :     * Doing something smarter than relying on MLTreeGen on architectures
4023 :     like, e.g., the x86 where hardware division delivers both quotient and
4024 :     remainder at the same time. With this, the implementation of the
4025 :     round-to-neginf operations could be further streamlined.
4026 :    
4027 :     * Remove inlining support for div/mod/rem from the frontend and replace it
4028 :     with primops that get carried through to the backend. Do this for all
4029 :     int and word types.

4034 :     Tag: blume-20020325-divmod
4035 :     Description:
4036 :    
4037 :     I improved (hopefully without breaking them) the implementation of Int.div,
4038 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
4039 :     advantage of the following observations:
4040 :    
4041 :     Let q = x quot y r = x rem y
4042 :     d = x div y m = x mod y
4043 :    
4044 :     where "quot" is the round-to-zero version of integer division that
4045 :     hardware usually provides. Then we have:
4046 :    
4047 :     r = x - q * y where neither the * nor the - will overflow
4048 :     d = if q >= 0 orelse x = q * y then q else q - 1
4049 :     where neither the * nor the - will overflow
4050 :     m = if q >= 0 orelse r = 0 then r else r + y
4051 :     where the + will not overflow
4052 :    
4053 :     This results in substantial simplification of the generated code.
4054 :     The following table shows the number of CFG nodes and edges generated
4055 :     for
4056 :     fun f (x, y) = x OPER y
4057 :     (* with OPER \in div, mod, quot, rem *)
4058 :    
4059 :    
4060 :     OPER | nodes(old) | edges(old) | nodes(new) | edges(new)
4061 :     --------------------------------------------------------

4098 :     Description:
4099 :    
4100 :     1. Changes to FLINT primops:
4101 :    
4102 :     (* make a call to a C-function;
4103 :     * The primop carries C function prototype information and specifies
4104 :     * which of its (ML-) arguments are floating point. C prototype
4105 :     * information is for use by the backend, ML information is for
4106 :     * use by the CPS converter. *)
4107 :     | RAW_CCALL of { c_proto: CTypes.c_proto,
4108 :     ml_args: ccall_type list,
4109 :     ml_res_opt: ccall_type option,
4110 :     reentrant : bool
4111 :     } option
4112 :     (* Allocate uninitialized storage on the heap.
4113 :     * The record is meant to hold short-lived C objects, i.e., they
4114 : blume 2155 * are not ML pointers. With the tag, the representation is
4115 : leunga 1174 * the same as RECORD with tag tag_raw32 (sz=4), or tag_fblock (sz=8)
4116 :     *)
4117 : blume 2155 | RAW_RECORD of {tag:bool,sz:int}
4118 : leunga 1174 and ccall_type = CCALL_INT32 | CCALL_REAL64 | CCALL_ML_PTR
4119 :    
4120 :     2. These CPS primops are now overloaded:
4121 :    
4122 :     rawload of {kind:numkind}
4123 :     rawstore of {kind:numkind}
4124 :    
4125 :     The one argument form is:
4126 :    
4127 :     rawload {kind} address
4128 :    
4129 :     The two argument form is:
4130 : blume 2155
4131 : leunga 1174 rawload {kind} [ml object, byte-offset]
4132 :    
4133 :     3. RAW_CCALL/RCC now takes two extra arguments:
4134 :    
4135 :     a. The first is whether the C call is reentrant, i.e., whether
4136 :     ML state should be saved and restored.
4137 :     b. The second argument is a string argument specifying the name of
4138 :     library and the C function.
4139 :    
4140 :     These things are currently not handled in the code generator, yet.
4141 :    
4142 :     4. In CProto,
4143 :    
4144 : blume 2155 An encoding type of "bool" means "ml object" and is mapped into
4145 :     C prototype of PTR. Note that "bool" is different than "string",
4146 : leunga 1174 even though "string" is also mapped into PTR, because "bool"
4147 :     is assigned an CPS type of BOGt, while "string" is assigned INT32t.
4148 :    
4149 :     5. Pickler/unpicker
4150 :    
4151 :     Changed to handle RAW_RECORD and newest RAW_CCALL
4152 :    
4153 :     6. MLRiscGen,
4154 :    
4155 :     1. Changed to handle the new rawload/rawstore/rawrecord operators.
4156 :     2. Code for handling C Calls has been moved to a new module CPSCCalls,
4157 :     in the file CodeGen/cpscompile/cps-c-calls.sml
4158 :    
4159 :     7. Added the conditional move operator
4160 :    
4161 :     condmove of branch
4162 :    
4163 : blume 2155 to cps. Generation of this is still buggy so it is currently
4164 : leunga 1174 disabled.

4170 : george 1168 Description:
4171 :    
4172 : blume 2155 Implemented the Ball-Larus branch prediction-heuristics, and
4173 : george 1168 incorporated graphical viewers for control flow graphs.
4174 :    
4175 : george 1171 Ball-Larus Heuristics:
4176 : george 1168 ---------------------
4177 :     See the file compiler/CodeGen/cpscompile/cpsBranchProb.sml.
4178 :    
4179 :     By design it uses the Dempster-Shafer theory for combining
4180 :     probabilities. For example, in the function:
4181 :    
4182 :     fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)
4183 :    
4184 :     the ball-larus heuristics predicts that the n=0 is unlikely
4185 :     (OH-heuristic), and the 'then' branch is unlikely because of the
4186 :     RH-heuristic -- giving the 'then' branch an even lower combined
4187 : george 1171 probability using the Dempster-Shafer theory.
4188 : george 1168
4189 :     Finally, John Reppy's loop analysis in MLRISC, further lowers the
4190 :     probability of the 'then' branch because of the loop in the else
4191 :     branch.
