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

346 :     will be forced to run regardless of whether or not their targets
347 :     are up-to-date
348 :     - changed installer code so that config/install.sh will re-build

373 :     Date: 2007/05/31 14:55:00 CDT
374 :     Revision: 2650
375 :     Description:
376 :    
377 :     3rd merge of base from primop-branch-3 into the trunk.
378 :     Additional bug fixes included:
379 :    
380 :     * Timer.cpu_timer, etc. type printing corrected (by making
381 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
382 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
383 :     Stefan Monnier)

386 : blume 2645 Name: Matthias Blume (http://www.tti-c.org/blume/)
387 :     Date: 2007/05/31 11:40:00 CDT
388 :     Description:
389 :    
390 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
391 :    
392 :     Also, changed the handling of "no core access": When translate.sml
393 :     needs access to a core exception at a time when the core has not
394 :     been set up yet (this only happens when compiling system/smlnj/init/*),
395 :     then don't bother generating the corresponding tests.
396 :    
397 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
398 :     the exception. Unfortunately, that confuses the plambda type checker.
399 :     Moreover, it does not do any good, because at runtime we don't expect
400 :     such an exception to be ever raised. (The code in system/smlnj/init/*
401 :     has to be written very carefully with this in mind!)

412 :     Date: 2007/05/29 19:00:00 CDT
413 :     Description:
414 :    
415 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
416 :     with an explicit test for zero division. This should fixes several
417 :     regressions and makes it possible for downstream optimization phases
418 :     to treat these operations as "pure" when they are applied to unsigned
419 :     operands.

437 :     lie outside the specified set.

442 :     Description:
443 :    
444 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
445 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
446 :    
447 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
448 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
449 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
450 :     while running CMB.make. The point is that the single symbol
451 :     NO_PLUGINS is definde in all three cases.)
452 :    
453 :     I changed the three locations within the sources that get compiled
454 :     during CMB.make where ml-yacc or ml-lex input is processed: When
455 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
456 :     is bypassed.
457 :    
458 :     When bootstrapping new versions of the compiler, there can be
459 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
460 :     are not available or otherwise not operational. In this case one can
461 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
462 :     do so, the following command should be issued at the interactive
463 :     prompt:
464 :    
465 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
466 :    
467 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
468 :     files that normally would be generated by ml-yacc and ml-lex.
469 :     (Copies of these files are in the repository.)

476 :    
477 :     2nd merge of base from primop-branch-3 into the trunk.

485 :     Description:
486 :    
487 :     Changed the installation mechanism for CM tool plugins. These are
488 :     just libaries and now get installed like ordinary libaries.
489 :    
490 :     There are now a number of new installation targets that give some
491 :     fine-grain control over what classes and suffixes are known, and what
492 :     they will map to.
493 :     See config/targets for details.
494 :    
495 :     The code that caused plugin installation as part of running a
496 :     tool's "build" script has been removed. (The build script is for
497 :     building, not for installing.)

502 :     Description:
503 :    
504 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
505 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
506 :     CM fail if a shell tool reports a non-success exit status. If
507 :     the control is set to true, then CM will press on after tool failures
508 :     in the event that the target files exist (even though they are
509 :     considered outdated). Turning the control to true can be useful for
510 :     bootstrapping.

515 :     Description:
516 :    
517 :     Merge of ml-lpt revisions for 110.64.
518 :    
519 :     The name of several ml-lpt-lib modules has changed:
520 :     Repair => AntlrRepair
521 :     StreamPos => AntlrStreamPos
522 :     ErrHandlerFn => AntlrErrHandler
523 :     EBNF => AntlrEBNF
524 :    
525 :     The ml-antlr specification format has changed: declarations such as
526 :     %tokens and nonterminal definitions can occur *multiple* times in the
527 :     same specification. The semantics are such that each new declaration
528 :     extends the previous ones. This does not apply to %start or %name,
529 :     of course.
530 :    
531 :     Importing a grammar via %import now includes *all* declarations in from
532 :     the imported grammar, except for %name, %entry, and %start. Tokens
533 :     and nonterminals can be dropped using the new %dropping clause of the
534 :     %import directive; the separate %drop and %extend have been removed.
535 :    
536 :     We now allow optional type annotations on nonterminals, using the %nonterms
537 :     directive as in ml-yacc.
538 :    
539 :     The refcell construct is now implemented using SML's regular reference
540 :     cells, so the :== and !! notation has been deprecated.
541 :    
542 :     The ml-antlr tool now does much more checking of specifications, and
543 :     its error messages have been greatly improved. Error repair for
544 :     generated parsers has been completely rewritten, and is now both
545 :     much faster and more accurate.
546 :    
547 :     ml-ulex is now more lenient with escape codes (non-SML-standard
548 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
549 :     Also, character classes may now include a "-" character at the beginning
550 :     as is standard in most other regexp tools.
551 :    
552 :     All of these changes are documented in the user guide, which has
553 :     been updated and improved with this merge.

704 :     Description:
705 :    
706 :     Added preliminary support in MLRISC for Staged Allocation, a technique
707 :     for specifying calling conventions (see
708 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
709 :     Initially, we plan to use this code to generate C calls for the AMD64.
710 :    
711 :     The staged allocation code base resides in MLRISC/staged-allocation,
712 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

776 :     Date: 2007/01/31
777 :     Description:
778 :    
779 :     Brought ml-lpt manual up-to-date with the code. Many minor
780 :     improvements to the tools, and a few minor bugfixes. Prepared
781 :     ml-lpt-lib for integration with new UTF8 structure. Changed
782 :     the interface for creating streams in ml-ulex (we now support
783 :     stream creation from several kinds of sources). Overall, the
784 :     tools are now quite stable, and their interfaces are unlikely to
785 :     change in a way that would break compatibility. More work,
786 :     however, is needed in the documentation.

791 :     Description:
792 :    
793 :     Implemented library installer. Moved CM plugin code for
794 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
795 :     their respective trees. Implemented CM plugin for ml-ulex
796 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
797 :     and ml-antlr.
798 :    
799 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
800 :     CM tools. (It turns out to be too messy to do otherwise because
801 :     there is too much code that during installation relies on the presence
802 :     of these tools -- resulting in a tricky ordering problem.)

807 :     Description:
808 :    
809 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
810 :     Modified CM's startup code to use shiftArgs as it processes
811 :     command line arguments. This way, the init code in each .sml-file
812 :     or library that is mentioned at the top level will see only
813 :     those arguments that have not yet been processed at this point.
814 :     In other words, the init code can "seize control" and process the
815 :     remaining command line.

871 :     Description:
872 :    
873 :     Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to
874 :     get the c_cc termios data copied correctly. Also moved the allocation
875 :     of the string to avoid problems if it caused a GC.
876 :    
877 :     Thanks to Timothy Bourke for the bug report and fix.

881 :     Date: 2006/12/08 09:50:00 CST
882 :     Description:
883 :    
884 :     Added code to CM's "standard shell tool" implementation which
885 :     causes it to tolerate (with a warning) the situation where the shell
886 :     command fails (e.g., due to the shell command's non-existence)
887 :     as long as all target files exist.
888 :    
889 :     This makes it possible to, e.g., build ml-yacc from sources even if
890 :     svn checkout messed up the time stamps on files in such a way that
891 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
892 :     be needed to re-process yacc.grm, but obviously it might not yet be
893 :     available at that time.)

898 :     Description:
899 :    
900 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
901 :     recvVecFromNB' in the SOCKET signature. This error is actually
902 :     in the SML Basis specification too.

907 :     Description:
908 :

915 :     Description:
916 :    
917 :     Use Say.vsay for printing the "[autoloading]" message, so
918 :     #set CM.Control.verbose false (or -Ccm.verbose=false) can be used
919 :     to suppress them.

932 :     Tag: release-110.60
933 :     Description:
934 :    
935 :     New working release (110.60). NEW BOOTFILES!
936 :    
937 :     This is the first subversion-hosted release. There are also changes
938 :     to the directory layout. Here is a table:
939 :    
940 :     (All pathnames are relative to the SML/NJ "root" directory.)
941 :    
942 :     config -> config
943 :    
944 :     src/cm -> base/cm
945 :     src/compiler -> base/compiler
946 :     src/runtime -> base/runtime
947 :     src/system -> base/system
948 :    
949 :     src/cm/pgraph -> pgraph
950 :    
951 :     src/READMES -> base/READMES
952 :     src/$notefile -> base/NOTES/$notefile
953 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
954 :     MACOSXINSTALL WININSTALL
955 :    
956 :     src/smlnj-lib -> smlnj-lib
957 :     src/MLRISC -> MLRISC
958 :     ckit -> ckit
959 :     src/cml -> cml
960 :     src/eXene -> eXene
961 :     src/heap2asm -> heap2asm
962 :     src/lexgen -> lexgen
963 :     src/ml-burg -> ml-burg
964 :     src/ml-lex -> ml-lex
965 :     src/ml-yacc -> ml-yacc
966 :     src/ml-nlffi-lib -> nlffi/lib
967 :     src/ml-nlffigen -> nlffi/gen
968 :     src/smlnj-c -> smlnj-c
969 :     src/tools/TraceDebugProf -> trace-debug-profile
970 :    
971 :     In addition, there is also a new
972 :    
973 :     ml-lpt
974 :    
975 :     directory containing two new program generator tools: ml-ulex and
976 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
977 :     LL(k) parser generator). These tools are currently "beta-quality"
978 :    
979 :     The latest versios of the sources can now be obtained anonymously
980 :     via subversion. For this, it is useful to first check out
981 :    
982 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
983 :    
984 :     and put the resulting directory on your shell's PATH. This provides
985 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
986 :     and refresh-all.sh.
987 :    
988 :     To create a freshly checked-out copy of the sources, do
989 :    
990 :     checkout-all.sh [dir]
991 :    
992 :     where dir is the optional SML/NJ root directory (default is ".").
993 :    
994 :     This creates the above directory layout. Each subdirectory of
995 :     the root is under individual subversion control. The stat-all.sh
996 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
997 :     each of these subtrees.
998 :

1000 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
1001 : blume 2155 Date: 2006/11/02 12:20:00 CST
1002 :     Description:
1003 :    
1004 :     Reorganized directory layout.
1005 :    
1006 :     This is a temporary solution, more reorganization is to come.
1007 :    
1008 :     The basic idea is to have a number of toplevel trees, each corresponding
1009 :     to a well-defined part of the overall system. Each part can be
1010 :     maintained individually, even in separate source repositories,
1011 :     although currently we still serve everything out of the main
1012 :     smlnj-gforge tree.
1013 :    
1014 :     Installer and and scripts have been updated to reflect the new
1015 :     layout. The installer (base/src/system/smlnj/installer) is now
1016 :     "scriptable" to avoid burning too much knowledge about the
1017 :     layout into SML source code. The main script used by the installer
1018 :     is in config/actions.
1019 :    
1020 :     The main change is that many of the subdirectories of what used to
1021 :     be known as "src" have moved to the toplevel. The "src" directory
1022 :     itself has moved down into a subtree called "base". (We may eventually
1023 :     get rid of the extra level of indirection represented by "src".)
1024 :    
1025 :     The layout is now as follows:
1026 :    
1027 :     toplevel tree name | default repository
1028 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1029 :     -------------------+----------------------------------------------------
1030 :     config | $gf/config/trunk
1031 :     |
1032 :     base | $gf/sml/trunk
1033 :     |
1034 :     smlnj-lib | $gf/smlnj-lib/trunk
1035 :     MLRISC | $gf/MLRISC/trunk
1036 :     |
1037 :     ml-yacc | $gf/ml-yacc/trunk
1038 :     ml-lex | $gf/ml-lex/trunk
1039 :     ml-burg | $gf/ml-burg/trunk
1040 :     lexgen | $gf/lexgen/trunk
1041 :     heap2asm | $gf/heap2asm/trunk
1042 :     |
1043 :     cml | $gf/cml/trunk
1044 :     eXene | $gf/eXene/trunk
1045 :     ckit | $gf/ckit/trunk
1046 :     nlffi | $gf/nlffi/trunk
1047 :     |
1048 :     smlnj-c | $gf/smlnj-c/trunk
1049 :    
1050 :     In $gf/admin there are a few useful shell scripts for checking out
1051 :     and maintaining the entire collection of trees:
1052 :    
1053 :     admin/checkout-all.sh [dir]
1054 :     -- optionally creates dir and checks out all trees from their
1055 :     default repositories; if dir is missing, checkout into .
1056 :     admin/refresh-all.sh [dir]
1057 :     -- looks at all trees (from the above list) in dir (default: .)
1058 :     and runs "svn update" if the tree exists and is under
1059 :     subversion control;
1060 :     non-existing or non-subversion trees are skipped
1061 :     admin/stat-all.sh [dir]
1062 :     -- like refresh-all.sh, but runs "svn stat" instead

1210 :     Hooked code for Darwin-specific Intel ABI into main compiler.
1211 :     (This is a temporary solution which relies on the fact that the

1245 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1246 : blume 2155 at the time when config/preloads is processed, the library has to
1247 : mblume 1878 be referred to by another name. In 110.57 this would be

1304 :     Tag: blume-22051115-versiontool
1305 :     Description:
1306 :    
1307 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1308 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1309 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1310 :     it. Instead, it has the status of "user code", so it should use
1311 :     $/basis.cm to refer to the Basis library. (At least that's true for
1312 :     the purpose of bootstrapping the previous change. In the future it
1313 :     might make sense to have versiontool.cm refer to
1314 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1315 :     compiler itself uses.)
1316 :    
1317 :     Also patched src/system/testml to have it activate those extra anchor
1318 :     bindings in config/extrapathconfig.

1322 : mblume 1863 Date: 2005/11/15 16:35:00 CST
1323 :     Tag: blume-22051115-libraries
1324 :     Description:
1325 :    
1326 :     This change affects the way the following libraries are tied into
1327 :     the system:
1328 :    
1329 :     $/basis.cm
1330 :     $/smlnj-lib.cm
1331 :     $/pp-lib.cm
1332 :     $/controls-lib.cm
1333 :     $/html-lib.cm
1334 :     $/ml-yacc-lib.cm
1335 :    
1336 :     These libraries are now internally (as seen from the source code
1337 :     of the implementation itself) known by the following names:
1338 :    
1339 :     $smlnj/basis/basis.cm
1340 :     $smlnj/smlnj-lib/smlnj-lib.cm
1341 :     $smlnj/smlnj-lib/pp-lib.cm
1342 :     $smlnj/smlnj-lib/controls-lib.cm
1343 :     $smlnj/smlnj-lib/html-lib.cm
1344 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1345 :    
1346 :     This makes it possible to work with code that requires different
1347 :     versions of these libraries, and which refers to these libraries using
1348 :     their "default" names (i.e., the first set of names above). In other
1349 :     words, one can un-define or re-define those default names without
1350 :     compromising the proper functioning of the compiler itself.
1351 :    
1352 :     A similar procedure had already been performed for several of the
1353 :     MLRISC libraries that are linked into the compiler. I did some
1354 :     cleanup on this code.
1355 :    
1356 :     A new file in the config directory (named extrapathconfig) is
1357 :     responsible for setting up path anchors that the compiler itself does
1358 :     not need, but that are typically required by user code.

1368 :     out the problem.)

1537 :     Tag: blume-20050516-redump-heap
1538 :     Description:
1539 :    
1540 :     Added mechanism for re-creating a heap file for the interactive system
1541 :     after configuration variables have been changed.
1542 :    
1543 :     CM.redump_heap : string -> unit
1544 :    
1545 :     This is much like SMLofNJ.exportML, but starting from the resulting
1546 : blume 2155 heap does not return to the caller of CM.redump_heap but
1547 : mblume 1792 restarts the interactive system from scratch. The original call of
1548 :     CM.redump_heap does not return but ends the interactive session.
1549 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1550 :    
1551 :     Internally, redump_heap winds the dynamic execution context back to
1552 :     the point where the original heap image was created and re-executes
1553 :     the heap image generation code in the boot code.

1669 :     Tag: blume-20050114-heap2exec
1670 :     Description:
1671 :    
1672 :     Implemented new (but still experimental) heap2exec facility. This is
1673 :     tested under Mac OS X and should work under Linux (will test shortly).
1674 :     It will probably also work on the Sparc (will test some time later).
1675 :    
1676 :     - removed old "HACKED_STANDALONE" hack from runtime
1677 :    
1678 :     To be able to test this, uncomment the request for "heap2asm" in
1679 :     config/targets prior to installation. (Notice that this is different
1680 :     from "heap2exec" mentioned below. Not a typo.)
1681 :    
1682 :     To perform an actual test, run the command
1683 :    
1684 :     $ bin/heap2exec heapfile execfile
1685 :    
1686 :     (You can put heap2exec on your shell's path.)
1687 :    
1688 :     For example, run
1689 :    
1690 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1691 :    
1692 :     This will create a standalone executable called "mly" which you can
1693 :     then invoke directly as a command.

1838 :     Tag: blume-20041124-position
1839 :     Description:
1840 :    
1841 :     The compiler can now be compiled in a mode that makes structure Position
1842 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1843 :     for the time being.
1844 :    
1845 :     To enable 64-bit positions, use the following procedure:
1846 :    
1847 :     1. Start sml
1848 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1849 :     3. Type
1850 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1851 :     4. Run CMB.make() as usual.
1852 :    
1853 :     This is barely tested. The only test so far was a little SML program
1854 :     counting the number of characters in an 8-gigabyte file by
1855 :     reading it character-by-character. That test was successful.
1856 :    
1857 :     In support of 64-bit positions, a number of new functions have been
1858 :     added to the runtime system.

1903 :    
1904 :     - In a previous commit, fixed a minor issue with how polyequal is being
1905 :     translated. In particular, the code now "looks through" abstractions.
1906 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1907 :     more efficient code. Important examples for where this matters are
1908 :     the new int64 and word64 types.

1925 :     All the pieces of Word64 are now there, with the exception of the
1926 :     conversions from and to LargeWord. (Eventually these need to be identities,
1927 :     but for the time being they don't even make sense because LargeWord is
1928 :     32-bit wide.)
1929 :    
1930 :     Also started to add similar support for Int64, but major pieces of that
1931 :     are still missing.

1937 :     Description:
1938 :    
1939 :     Structure Word64 is now (almost) complete, word literals and patterns
1940 :     seem to work. There are a few odd pieces missing. In particular,
1941 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1942 :     at the moment.
1943 :    
1944 :     Making Word64 official would mean that LargeWord becomes Word64. But
1945 :     this requires extreme care because most word-word conversions have to
1946 :     go through LargeWord, so making a mistake means loss of efficiency or
1947 :     worse. Eventually there will be a solution similar to (but actually
1948 :     simpler than) what I did with IntInf.

1985 :     normally does not have to be edited to reflect a version change.
1986 :    
1987 :     (As a result, a version change can be done by just editing

2028 :     Tag: blume-20041020-standalone-backtrace
2029 :     Description:
2030 :    
2031 :     Added a mechanism for getting back-trace information from standalone
2032 :     programs. Here is how it works:
2033 :    
2034 :     1. The part of the program from which you want to get backtrace
2035 :     information (usually the whole program) should be wrapped with
2036 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
2037 :     main program could be modified from something like
2038 :    
2039 :     fun main (pgm, args) = ...
2040 :    
2041 :     to
2042 :    
2043 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2044 :    
2045 :     2. To be able to access BackTrace.monitor, you have to add
2046 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
2047 :     main function.
2048 :    
2049 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2050 :     CM might have created in the past for your project).
2051 :    
2052 :     4. Build the system using this command line:
2053 :    
2054 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2055 :     myprog.cm MyProg.main myprog
2056 :    
2057 :     instead of the usual
2058 :    
2059 :     ml-build myprog.cm MyProg.main myprog
2060 :    
2061 :     I changed a library name:
2062 :    
2063 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2064 :    
2065 :     New libraries:
2066 :    
2067 :     $smlnj-tdp/back-trace.cm
2068 :     -- when loaded causes the back-trace plugin to be installed
2069 :     $smlnj-tdp/coverage.cm
2070 :     -- when loaded causes the coverage plugin to be installed

2089 :     * Further reorganization of tracing-, debugging-, and profiling support:
2090 :    
2091 :     - moved original BTImp -- now called BackTrace -- into a separate
2092 :     library called $/trace-debug-profile.cm
2093 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2094 :     - only the instrumentation mechanism is now left in the compiler proper
2095 :     - BackTrace module is a plugin which is NOT plugged in by default
2096 :     - Coverage module is another such plugin
2097 :    
2098 :     To get the benefits of any of these plugin modules, the code in
2099 :     question must be compiled with tdp instrumentation turned on. This
2100 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2101 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2102 :    
2103 :     Plugins are selected at link time. (Pre-compiled instrumented code
2104 :     can be re-loaded with different plugins in effect.) When an
2105 :     instrumented module is linked, whatever plugins are at that time
2106 :     enabled will come into effect for that module.
2107 :    
2108 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2109 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2110 :     To enable the coverage plugin, load the same library and invoke
2111 :     Coverage.install().
2112 :    
2113 :     Back-traces are generated automatically on uncaught exceptions and
2114 :     when the code in question explicitly invokes BackTrace.trigger().
2115 :    
2116 :     Coverage (and execution frequency-) information must be queried
2117 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2142 :    
2143 :     The control flag controlling whether instrumentation is on or off is now

2171 :    
2172 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool
2173 :     is supposed to accept a tool argument called "source", but this did
2174 :     not work because of the clash with the keyword.

2218 :    
2219 :     * Moved the "version" magic into its own little library under

2225 : mblume 1639
2226 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2227 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2228 :     Also, loading the versiontool does not work when rebuilding the system
2229 :     because CM is not properly initialized at that time.

2234 :     Tag: blume-20040929-autoversion
2235 :     Description:
2236 :    
2237 :     Implemented some CM magic to have
2238 :     file src/compiler/TopLevel/main/version.sml
2239 :     generated automagically.
2240 :     The version is taken from two files: config/version and config/release.
2241 :     The first is expected to contain a two-part version number such as 110.49.
2242 :     The second should contain a single number, but it may be missing.
2243 :    
2244 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2245 :     time the version tool is loaded (which is the first time you say CMB.make),
2246 :     then the tool will increment the value stored in config/release every
2247 :     time CMB.make is invoked.
2248 :    
2249 :     The binfile format is now insensitive to anything beyond the first
2250 :     two components of a version number, so bumping the release does not render
2251 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2252 :     during development without invalidating existing binfiles.
2253 :    
2254 :     In any case, every CMB.make updates the date information in version.sml.
2255 :     (This is the date that is printed in the banner.)

2268 :     Tag: blume-20040927-controls
2269 :     Description:
2270 :    
2271 :     Added two pieces of functionality to the Controls interface:
2272 :    
2273 :     1. val save'restore: 'a control -> unit -> unit
2274 :    
2275 :     grabs the current value of the control in stage 1 and restores it
2276 :     in stage 2.
2277 :    
2278 :     2. val set' : 'a control * 'a -> unit -> unit
2279 :    
2280 :     stores the given value into the control in stage 2 (i.e., delayed)
2281 :     but does all error checking in stage 1.
2282 :     (This is for string controls that need to do parse their argument --
2283 :     something that might fail. In some cases, notably in CM, one
2284 :     already knows the intended argument but wants to delay the actual
2285 :     assignment until a time when error recovery would be more difficult.)
2286 :    
2287 :     Changed the handling of controls in tool arguments to classes "sml" and
2288 :     "lazysml":
2289 :     - use Controls.save'restore as a more robust way of restoring the
2290 :     old value (in particular: without having to re-parse the string)
2291 :     - use controls to handle the "overload" keyword in the init group
2292 :     (I believe this change actually fixes a long-standing obscure bug.)

2297 :     Tag: blume-20040927-lazysml
2298 :     Description:
2299 :    
2300 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2301 :     difference to "sml" is that compilation is done with Control.lazysml
2302 :     set to true. A source of class "lazysml" is automatically recognized
2303 :     by a file name suffix of ".lml".
2304 :    
2305 :     In addition to the above feature, the original class "sml" now also
2306 :     supports a tool argument "lazy" which has the same effect. As a
2307 :     result, the following three lines are equivalent:
2308 :    
2309 :     foo.sml : lazysml
2310 :     foo.sml : sml (lazy)
2311 :     foo.sml (lazy)
2312 :    
2313 :     The setting goes into effect both during parsing and during
2314 :     compilation. The original setting is restored right after parsing and
2315 :     after compilation, respectively.
2316 :    
2317 :     In addition to all the above, there is also a general mechanism to set
2318 :     ANY of the "controls" that are available at the command line via
2319 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2320 :     apply as well. (In fact, "lazy" is implemented as a special case of
2321 :     the general mechanism.)
2322 :    
2323 :     The .cm file syntax uses a new keyword tool argument called "with".
2324 :     There are several ways of indicating the desired settings:
2325 :    
2326 :     foo.sml (with:parser.quotations=true)
2327 :     foo.sml (with:(name:parser.quotations value:true))
2328 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2329 :     foo.sml (with:(name1=value1 name2=value2 ...))
2330 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2331 :    
2332 :     etc.
2333 :    
2334 :     Another possible abbreviation is to leave out the =v or value:v part
2335 :     if the name refers to a boolean control (in which case the value is
2336 :     taken to be true). Thus, one could get lazy sml also by saying:
2337 :    
2338 :     foo.sml (with:parser.lazy-keyword=true)
2339 :     foo.sml (with:parser.lazy-keyword)
2340 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2341 :     foo.sml (with:(name:parser.lazy-keyword))

2693 :     Description:
2694 :    
2695 :     Changed the interface of structures Timer and Unix to match the most
2696 :     recent Basis spec.
2697 :    
2698 :     In the case of Unix there still seems to be an open/weird issue:
2699 :    
2700 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2701 :     fresh streams whenever they are called -- as opposed to have them
2702 :     return the same stream every time. This design is supposed to
2703 :     prevent space leaks caused by proc values hanging on to streams.
2704 :    
2705 :     The reap function, on the other hand, is supposed to close the
2706 :     streams. This cannot be done without having a handle on the
2707 :     stream in proc after all...
2708 :    
2709 :     I took the liberty to implement the following stopgap solution:
2710 :    
2711 :     The proc value hangs on to the most recently created stream(s).
2712 :     Reap closes those. If either or both of the two streams hadn't
2713 :     been created at all yet, then reap will close the corresponding
2714 :     file descriptors directly.
2715 :    
2716 :     PS: I don't understand the original space leak argument anymore. If
2717 :     a proc hangs on to the imperative stream, then I/O operations on those
2718 :     will advance the state of the cached stream and avoid the space leak.

2731 :     Tag: blume-20040525-group-owner
2732 :     Description:
2733 :    
2734 :     CM now ignores (but still accepts) the "owner" information in group
2735 :     descriptions. The owner of a group is its next enclosing
2736 :     library. Each group must have a unique owner. (There is a virtual
2737 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2738 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2739 :     and CM would check that such a declaration is correct. The new scheme
2740 :     is to have CM check that for each group there is precisely one owning
2741 :     library.
2742 :    
2743 :     The advantage of the new scheme is that the programmer no longer needs
2744 :     to maintain the somewhat annoying owner information. The downside is
2745 :     that CM cannot enforce the ownership rule across multiple runs of
2746 :     CM.make. Fortunately, enclosing the same group in two different
2747 :     libraries A and B which are not part of the same program does not
2748 :     cause real problems.

2771 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
2772 :     gets rid of those at the end, so they don't accumulate under .cm.
2773 :    
2774 :     This required a minor change to install.sh because the name of the

2794 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
2795 :     for the voluminous patch!
2796 :    
2797 :     (I have not tested this patch under win32 yet.)
2798 :    
2799 : mblume 1490 Here is David's e-mail:
2800 :    
2801 :     Hi,
2802 :    
2803 :     Attached to this email you find a diff against sml/nj 110.45
2804 :     that will enable socket support under Windows.
2805 :    
2806 :     To apply the patch (using unix or cygwin)
2807 :     1) gunzip runtime.diff.gz
2808 :     2) "cd" into "src/runtime" in the source tree of a fresh
2809 :     110.45 installation.
2810 :     3) patch -p 1 < [your/path/to]runtime.diff
2811 :    
2812 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2813 :     I only ran a few tests for basic socket client functionality
2814 :     (which worked fine). Especially the functions that use ioctl
2815 : mblume 1490 are not tested at all and might not work (see below).
2816 :    
2817 :     I implemented this since we want to move to a newer version of sml/nj
2818 :     but need socket support in order to use it. This is the first time I
2819 :     even had a look at the sml/nj source, so please review my changes
2820 :     before making this part of the distribution! Here are a few issues
2821 : blume 2155 that I think might be better for someone to solve who is more
2822 : mblume 1490 familiar with the sml/nj source (and socket programming):
2823 :    
2824 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2825 :     exception since I could not figure out what the windows equivalent
2826 :     of these functions is
2827 :    
2828 :     - In sockets-osdep.h there are a some #include statements that are
2829 :     only used in a few files that include sockets-osdep.h
2830 :    
2831 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2832 :     does not process its return value since I don't know how to
2833 :     report an error upwards.
2834 :    
2835 :     - It would probably be good to have a call to WSACleanup() when
2836 : blume 2155 the library is unloaded (if there is such a possibility).
2837 : mblume 1490 Otherwise I think Windows will take care of this automatically
2838 :     when the process finishes.
2839 :    
2840 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2841 :     no idea if that is actually the proper replacement on Windows.
2842 :    
2843 :     - All these issues are marked in the code by "FIXME" comments.
2844 :    
2845 : blume 2155 We use sml/nj extensively in our products and are quite happy
2846 :     with it. I hope this contribution will help you.
2847 : mblume 1490
2848 :     Keep up the good work!

2886 :     has changed from "all sources required for the compiler" to "all sources
2887 :     the installer knows about". In other words, if you enable "src-smlnj"
2888 :     in the "targets" file, then the installer will pull in sources for
2889 :     everything. (Notice that this refers to source code only. Compiled
2890 :     code is still only installed for modules that were requested explicitly
2891 :     or which are required for other modules that were requested explicitly.)

2925 :     Description:
2926 :    
2927 :     Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
2928 :     of SML/NJ. The problem is that
2929 :    
2930 :     lib = dlopen(NULL, ...)
2931 :     f = dlsym(lib, "malloc");
2932 :    
2933 : blume 2155 does not work on Windows unless we explicitly export symbols
2934 :     such as 'malloc' during linking. We fixed this by explicitly
2935 : allenleung 1468 exporting the required symbols with the magic gcc incantation:
2936 :    
2937 :     -Wl,--export-all cygwin.def
2938 :    
2939 :     where cygwin.def is a file containing all the symbols that
2940 : blume 2155 we wish to export.
2941 : allenleung 1468
2942 : blume 2155 I suspect this is a Windows problem and we'll have to
2943 :     do the same (somehow with windows compilers) when
2944 : allenleung 1468 we build the native win32 version with the system
2945 : blume 2155 calls LoadLibrary/GetProcAddress.

3021 :     old CM is not an option, there is no reason to keep it around.)

3070 :     Tag: blume-20030926-ppautoload
3071 :     Description:
3072 :    
3073 :     I modified the read-eval-print loop so that the autoloader gets
3074 :     invoked whenever the prettyprinter tries to look up a symbol that
3075 :     is not currently defined in the toplevel environment but which
3076 :     appears in CM's autoload registry. As a result, we see far fewer of
3077 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3078 :    
3079 :     In addition to this I tried to clean up some pieces of the Basis
3080 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3081 :     instances of these ?.Foo.Bar.xxx names from being printed.
3082 :    
3083 :     The mechanism that picks names for types still needs some work, though.
3084 :     (Right now it seems that if there is a type A.t which is defined to
3085 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3086 :     "?.B.u" although the perhaps more sensible solution would be to use
3087 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3088 :     a chain of DEFtycs not farther than there are corresponding toplevel
3089 :     names in the current environment.)

3095 :     Description:
3096 :    
3097 :     Another installer tweak: All the ML code for the installer is now
3098 :     compiled during CMB.make and put into a little library called
3099 :     $smlnj/installer.cm. The installation then simply invokes
3100 :    
3101 :     sml -m $smlnj/installer.cm
3102 :    
3103 :     and everything happens automagically.
3104 :    
3105 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3106 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3107 :     and BINDIR.
3108 :    
3109 :     The new scheme guarantees that the ML code responsible for the installation
3110 :     is in sync with the APIs of the main system. Also, the installer is
3111 :     somewhat faster because the installer script is precompiled.

3123 :     structure.

3128 :     Tag: blume-20030924-sockets
3129 :     Description:
3130 :    
3131 :     1. Fixed SOCKET API and implementation to match Basis spec.
3132 :     This required changing the internal representation of sockets to one
3133 :     that remembers (for each socket file descriptor) whether it is currently
3134 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3135 :     call is made only if the state actually needs to change).
3136 :    
3137 :     2. OS-specific details of sockets were moved into separate files, thus
3138 :     making it possible to unify the bulk of the socket implementations
3139 :     between Unix and Win32.
3140 :    
3141 :     3. CML's socket API changed accordingly.
3142 :     (Note that we need to remove non-blocking functions from this API
3143 :     since they are redundant in the case of CML!)
3144 :    
3145 :     4. CML's socket implementation now makes use of non-blocking functions
3146 :     provided by Basis, thus removing all OS-dependent code from this part
3147 :     of CML.
3148 :    
3149 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3277 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3278 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3279 :     same as type int; under Win32 it isn't
3280 :     - fixed some slice-related problems in the win32-specific parts of CML
3281 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3282 :     (under Win32, the volume name is case-insensitive, and the
3283 :     OS.Path code compares volume names for equality)

3299 : mblume 1352 Tag: blume-20030905-slices-etc
3300 : mblume 1350 Description:
3301 :    
3302 :     1. Changed interface to vectors and arrays in Basis to match
3303 :     (draft) Basis spec.
3304 :     2. Added signatures and implementations of slices according to
3305 :     Basis spec.
3306 :     3. Edited source code throughout the system to make it compile again
3307 :     under 1. and 2. (In some cases code had to be added to have it
3308 :     match the new signatures.)
3309 :     4. MLRISC should be backward-compatible: the copies of the originals
3310 :     of files that needed to change under 3. were retained, the .cm files
3311 :     check the compiler version number and use old versions when
3312 :     appropriate.
3313 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3314 :     dirstream -> string option (in accordance with Basis spec).
3315 :     6. When generating code that counts lines, ml-lex used function
3316 :     CharVector.foldli, taking advantage of its old interface.
3317 :     This has been replaced with the corresponding code from
3318 :     CharVectorSlice. (html-lex must be re-lexed!)
3319 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3320 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3321 :     8. Removed temporary additions (fromInternal, toInternal) from the
3322 :     (now obsolete) IntInf in smlnj-lib/Util.
3323 :     9. Cleaned up structure Byte.
3324 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3325 :     Cleaned/corrected implementation of Date.
3326 :     (Still need to check for correctness; implement better canonicalizeDate.)
3327 :     11. Added "scan" to signature IEEE_REAL.
3328 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3329 :     mod and rem when second operand is 2 (for parity checks).]
3330 :     13. Changed representation of type Time.time, using a single IntInf.int
3331 :     value counting microseconds. This considerably simplified the
3332 :     implementation of structure Time. We now support negative time
3333 :     values; scan and fromString handle signs.
3334 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3335 :     ArraySlice).

3340 :     Tag: blume-20030828-intinf
3341 :     Description:
3342 :    
3343 :     This is a major update which comes with a version number bump
3344 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3345 :     and an implementation of IntInf in the Basis.
3346 :    
3347 :     There are a fairly large number of related changes and updates throughout
3348 :     the system:
3349 :    
3350 :     Basis:
3351 :     - Implemented IntInf.
3352 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3353 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3354 : mblume 1347 - Added FixedInt as a synonym for Int32.
3355 :    
3356 :     compiler:
3357 :     * Added support for a built-in intinf type.
3358 :     - literals
3359 :     - pattern matching
3360 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3361 :     - overloading on literals and operations
3362 :    
3363 :     This required adding a primitive type intinf, some additional
3364 :     primops, and implementations for several non-trivial intinf
3365 :     operations in Core. (The intinf type is completely abstract
3366 :     to the compiler; all operations get delegated back to the Core.)
3367 :    
3368 :     * Intinf equality is handled by polyequal. However, the compiler
3369 :     does not print its usual warning in this case (since polyequal
3370 :     is the right thing to do there).
3371 :    
3372 :     * Improved the organization of structure InlineT.
3373 :    
3374 :     * A word about conversion primops:
3375 :     If conversions involving intinf do not cancel out during
3376 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3377 : mblume 1347 Since all core access must be resolved already during the FLINT
3378 :     translate phase, it would be too late a the time of CPS contract
3379 : mblume 1348 to add new Core calls. For this reason, conversion primops
3380 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3381 :     they are supposed to convert, and 2. the Core function that
3382 :     can help with this conversion if necessary. If CPS contract
3383 : mblume 1348 eliminates a primop, then the associated Core function becomes
3384 :     dead and goes away. Intinf conversion primops that do not get
3385 :     eliminated by CPS contract get rewritten into calls of their
3386 :     core functions by a separate, new phase.
3387 : mblume 1347
3388 :     interactive system:
3389 :     - Control.Print.intinfDepth controls max length of intinf constants
3390 :     being printed. (Analogous to Control.Print.stringDepth.)
3391 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3392 :     duplicates; replaced some of the code with code that makes better
3393 :     use of library functionality.
3394 :    
3395 :     CM:
3396 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3397 :     are no longer silent.
3398 :    
3399 :     CKIT:
3400 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3401 :     in favor of LargeInt -- which is now the same as IntInf.
3402 :     CKIT-knowledgable people should check whether this is what's
3403 :     intended and otherwise change things back to using Int32 or
3404 :     FixedInt.
3405 :    
3406 :     Throughout the code:
3407 : mblume 1348 Started using IntInf.int literals and built-in operations
3408 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3418 :     These changes involve replacement of the emulated old prettyprinter

3427 :     Tag: blume-20030811-windows
3428 :     Description:
3429 :    
3430 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3431 :    
3432 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3433 :    
3434 :     This patch restores SML/NJ's ability to run under win32. There are a
3435 :     number of changes, including fixes for several bugs that had gone
3436 :     unnoticed until now:
3437 :    
3438 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3439 :     trying to run the win32 version from within cygwin.)
3440 :    
3441 :     - There are a number of simple .bat scripts that substitute for their
3442 :     corresponding Unix shell-scripts. (See below.)
3443 :    
3444 :     - The internals of ml-build have been modified slightly. The main
3445 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3446 :     using OS.Process.system, the ML process delegates this task back
3447 :     to the script. Otherwise problems arise in mixed environments such
3448 :     as Cygwin where scripts look and work like Unix scripts, but
3449 :     where OS.Process.system cannot run them.
3450 :    
3451 :     - In CM, the srcpath pickler used native pathname syntax -- which
3452 :     is incorrect in the case of cross-compilation. The new pickle format
3453 :     is independent of platform-specific naming conventions.
3454 :    
3455 :     - Path configuration files (such as lib/pathconfig) can now choose
3456 :     between native and standard syntax. Placing a line of the form
3457 :    
3458 :     standard!
3459 :    
3460 :     into the file causes all subsequent paths to be interpreted using
3461 :     CM standard pathname syntax (= Unix conventions); a line
3462 :    
3463 :     native!
3464 :    
3465 :     switches back to native style. This was needed so that
3466 :     path config files can be written portably, see src/system/pathconfig.
3467 :    
3468 :     - Runtime system:
3469 :    
3470 :     - win32-filesys.c: get_file_time and set_file_time now
3471 :     access modification time, not creation time.
3472 :    
3473 :     - I/O code made aware of new array representation.
3474 :    
3475 :     - Bug fixes in X86.prim.masm.
3476 :    
3477 :     - src/system/makeml made aware of win32. (For use under cygwin
3478 :     and other Unix-environments for windows.)
3479 :    
3480 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3481 :     which caused BinIO.inputAll to fail consistently.
3482 :    
3483 :     .bat scripts:
3484 :    
3485 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3486 :    
3487 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3488 :     applications (sml, ml-yacc, ml-lex).
3489 :     - ml-build.bat: analogous to ml-build.
3490 :     - config\install.bat: Analogous to config/install.sh. This requires
3491 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3492 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3493 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3494 :     and the bootfile hierarchy must have been unpacked under
3495 :     sml.boot.x86-win32.
3496 :     The script is very primitive and does a poor job at error checking.
3497 :     It only installs the base system, ml-lex, and ml-yacc. No other
3498 :     libraries are being installed (i.e., you get only those that
3499 :     are part of the compiler.)
3500 :     - link-sml.bat: analogous to .link-sml, but not currently used
3501 :    
3502 :     Unrelated bug fixes:
3503 :    
3504 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3505 :     types.
3506 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3507 :     otherwise.)

3531 :     Description:
3532 :    
3533 :     Two changes:
3534 :    
3535 :     1. Added a flag for controlling whether non-exhaustive bindings will
3536 :     be treated as errors (default is false).
3537 :     2. Cleaned up the *entire* source tree so that CMB.make goes through
3538 :     without a single non-exhaustive match- or bind warning.

3544 :     Description:
3545 :    
3546 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3547 :    
3548 :     This mainly affects the quality of error messages. However, some
3549 :     of the code is now more straightforward than before. (Treatment of
3550 :     the above four constructs in translate.sml is much simpler than
3551 :     the "macro-expansion" that was going on before. Plus, the mach-
3552 :     compiler no longer gets invoked just to be able to compile an
3553 :     if-expression.)
3554 :    
3555 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3556 :     interactive loop.

3574 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3575 :

3675 :     to be in $SMLNJ_HOME/lib/pathconfig. This way one can easily move

3732 :    
3733 :     Another small change is that ppDec tries to give more information

3735 :     broken in some mysterious way if the functor's body's signature
3736 :     has not been declared by ascription but gets inferred from the
3737 :     implementation. This needs fixing...

3807 :     * Removed again all the stuff from config/preloads that one wouldn't

3837 :    
3838 :     0. John Reppy made several modifications to the SML/NJ library.
3839 :     In particular, there is a shiny new controls-lib.cm.
3840 :    
3841 :     1. Pushed new controls interface through compiler so that everything
3842 :     compiles again.
3843 :    
3844 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3845 :     SML/NJ library (so that CML compiles again).
3846 :    
3847 :     3. Modified init scripts because XXX_DEFAULT environment variables
3848 :     are no longer with us. (Boot-time initialization is now done
3849 :     using the same environment variables that are also used for
3850 :     startup-time initialization of controls.)

3856 :     Description:
3857 :    
3858 :     All pseudo-ops emitted before the first segment declaration
3859 :     such as TEXT, DATA, and BSS directives are assumed to be global
3860 :     declarations and are emitted first in the assembly file. This is
3861 :     useful in a number of situations where one has pseudo-ops that are not
3862 :     specific to any segment, and also works around the constraint that one
3863 :     cannot have client pseudo-ops in the TEXT segment.
3864 :    
3865 :     Because no segment is associated with these declarations it is
3866 :     an error to allocate any space or objects before the first segment
3867 :     directive and an exception will be raised. However, we cannot make
3868 :     this check for client pseudo-ops.
3869 :    
3870 :     These top level declarations are a field in the CFG graph_info.
3871 :     In theory you can continue to add to this field after the CFG has been
3872 :     built -- provided you know what you are doing;-)

3895 :     Description:
3896 :    
3897 :     Applied the following bugfix provided by Emden Gansner:
3898 :    
3899 :     Output is corrupted when outputSubstr is used rather than output.
3900 :    
3901 : blume 2155 The problem occurs when a substring
3902 : blume 1189
3903 :     ss = (s, dataStart, dataLen)
3904 :    
3905 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3906 :     avail bytes of s, starting at index dataStart, are copied into the
3907 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3908 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3909 :     starting this copy at index dataStart+avail in s, the current code
3910 : blume 1189 starts the copy at index avail.
3911 :    
3912 :     Fix:
3913 :     In text-io-fn.sml, change line 695 from
3914 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3915 : blume 2155 to

3932 :     Description:
3933 :    
3934 :     Added full support for div/mod/rem/quot on the x86, using the machine
3935 :     instruction's two results (without clumsily recomputing the remainder)
3936 :     directly where appropriate.
3937 :    
3938 :     Some more extensive power-of-two support was added to the x86 instruction
3939 :     selector (avoiding expensive divs, mods, and muls where they can be
3940 :     replaced with cheaper shifts and masks). However, this sort of thing
3941 :     ought to be done earlier, e.g., within the CPS optimizer so that
3942 :     all architectures benefit from it.
3943 :    
3944 :     The compiler compiles to a fixed point, but changes might be somewhat
3945 :     fragile nevertheless. Please, report any strange things that you might
3946 :     see wrt. div/mod/quot/rem...

3956 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3957 :     The problem was with quotient = 0, because that alone does not tell

3968 :    
3969 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
3970 :    
3971 :     Primops have changed. This means that the bin/boot-file formats have
3972 :     changed as well.
3973 :    
3974 :     To make sure that there is no confusion, I made a new version.
3975 :    
3976 :    
3977 :     CHANGES:
3978 :    
3979 :     * removed REMT from mltree (remainder should never overflow).
3980 :    
3981 :     * added primops to deal with divisions of all flavors to the frontend
3982 :    
3983 :     * handled these primops all the way through so they map to their respective
3984 :     MLRISC support
3985 :    
3986 :     * used these primops in the implementation of Int, Int32, Word, Word32
3987 :    
3988 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3989 :    
3990 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
3991 :    
3992 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3993 :     floating point
3994 :    
3995 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3996 :     and Real (but Real.abs maps to a separate floating-point-only primop)
3997 :    
3998 :    
3999 :     TODO items:
4000 :    
4001 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
4002 :     instructions because the machine instruction encoder cannot handle
4003 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
4004 :     REM in the first place, and REM is supported by the x86 machine coder.)
4005 :    
4006 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
4007 :     selection phase. (The two can be streamlined because the hardware
4008 :     delivers both quotient and remainder at the same time anyway.)
4009 :    
4010 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
4011 :     (Currently the behavior is inconsistent both across architectures and
4012 :     wrt. the draft Basis spec.)
4013 :    
4014 :     * Word8 should eventually be handled natively, too.
4015 :    
4016 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
4017 :     as if there currently is no execution path that could trigger it in
4018 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
4019 :     hold for things like multiplication and division.)

4024 :     Tag: blume-20020327-mlrisc-divisions
4025 :     Description:
4026 :    
4027 :     Added support for all four division operations (ML's div, mod, quot,
4028 :     and rem) to MLRISC. In the course of doing so, I also rationalized
4029 :     the naming (no more annoying switch-around of DIV and QUOT), by
4030 :     parameterizing the operation by div_rounding_mode (which can be either
4031 :     DIV_TO_ZERO or DIV_TO_NEGINF).
4032 :    
4033 :     The generic MLTreeGen functor takes care of compiling all four
4034 :     operations down to only round-to-zero div.
4035 :    
4036 :     Missing pieces:
4037 :    
4038 :     * Doing something smarter than relying on MLTreeGen on architectures
4039 :     like, e.g., the x86 where hardware division delivers both quotient and
4040 :     remainder at the same time. With this, the implementation of the
4041 :     round-to-neginf operations could be further streamlined.
4042 :    
4043 :     * Remove inlining support for div/mod/rem from the frontend and replace it
4044 :     with primops that get carried through to the backend. Do this for all
4045 :     int and word types.

4050 :     Tag: blume-20020325-divmod
4051 :     Description:
4052 :    
4053 :     I improved (hopefully without breaking them) the implementation of Int.div,
4054 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
4055 :     advantage of the following observations:
4056 :    
4057 :     Let q = x quot y r = x rem y
4058 :     d = x div y m = x mod y
4059 :    
4060 :     where "quot" is the round-to-zero version of integer division that
4061 :     hardware usually provides. Then we have:
4062 :    
4063 :     r = x - q * y where neither the * nor the - will overflow
4064 :     d = if q >= 0 orelse x = q * y then q else q - 1
4065 :     where neither the * nor the - will overflow
4066 :     m = if q >= 0 orelse r = 0 then r else r + y
4067 :     where the + will not overflow
4068 :    
4069 :     This results in substantial simplification of the generated code.
4070 :     The following table shows the number of CFG nodes and edges generated
4071 :     for
4072 :     fun f (x, y) = x OPER y
4073 :     (* with OPER \in div, mod, quot, rem *)

4076 :     OPER | nodes(old) | edges(old) | nodes(new) | edges(new)

4096 :     Description:
4097 :    
4098 :     I did some cleanup to Allen's new primop code and
4099 :     replaced yesterday's bootfiles with new ones.
4100 :     (But they are stored in the same place.)

4114 :     Description:
4115 :    
4116 :     1. Changes to FLINT primops:
4117 :    
4118 :     (* make a call to a C-function;
4119 :     * The primop carries C function prototype information and specifies
4120 :     * which of its (ML-) arguments are floating point. C prototype
4121 :     * information is for use by the backend, ML information is for
4122 :     * use by the CPS converter. *)
4123 :     | RAW_CCALL of { c_proto: CTypes.c_proto,
4124 :     ml_args: ccall_type list,
4125 :     ml_res_opt: ccall_type option,
4126 :     reentrant : bool
4127 :     } option
4128 :     (* Allocate uninitialized storage on the heap.
4129 :     * The record is meant to hold short-lived C objects, i.e., they
4130 : blume 2155 * are not ML pointers. With the tag, the representation is
4131 : leunga 1174 * the same as RECORD with tag tag_raw32 (sz=4), or tag_fblock (sz=8)
4132 :     *)
4133 : blume 2155 | RAW_RECORD of {tag:bool,sz:int}
4134 : leunga 1174 and ccall_type = CCALL_INT32 | CCALL_REAL64 | CCALL_ML_PTR
4135 :    
4136 :     2. These CPS primops are now overloaded:
4137 :    
4138 :     rawload of {kind:numkind}
4139 :     rawstore of {kind:numkind}
4140 :    
4141 :     The one argument form is:
4142 :    
4143 :     rawload {kind} address
4144 :    
4145 :     The two argument form is:
4146 : blume 2155
4147 : leunga 1174 rawload {kind} [ml object, byte-offset]
4148 :    
4149 :     3. RAW_CCALL/RCC now takes two extra arguments:
4150 :    
4151 :     a. The first is whether the C call is reentrant, i.e., whether
4152 :     ML state should be saved and restored.
4153 :     b. The second argument is a string argument specifying the name of
4154 :     library and the C function.
4155 :    
4156 :     These things are currently not handled in the code generator, yet.
4157 :    
4158 :     4. In CProto,
4159 :    
4160 : blume 2155 An encoding type of "bool" means "ml object" and is mapped into
4161 :     C prototype of PTR. Note that "bool" is different than "string",
4162 : leunga 1174 even though "string" is also mapped into PTR, because "bool"
4163 :     is assigned an CPS type of BOGt, while "string" is assigned INT32t.
4164 :    
4165 :     5. Pickler/unpicker
4166 :    
4167 :     Changed to handle RAW_RECORD and newest RAW_CCALL
4168 :    
4169 :     6. MLRiscGen,
4170 :    
4171 :     1. Changed to handle the new rawload/rawstore/rawrecord operators.
4172 :     2. Code for handling C Calls has been moved to a new module CPSCCalls,
4173 :     in the file CodeGen/cpscompile/cps-c-calls.sml
4174 :    
4175 :     7. Added the conditional move operator
4176 :    
4177 :     condmove of branch
4178 :    
4179 : blume 2155 to cps. Generation of this is still buggy so it is currently
4180 : leunga 1174 disabled.
