333 :    
334 :     - Aaron: fixed a number of bugs in ml-ulex.
335 :     - Matthias:
336 :     - added CM control "cm.force-tools"; this is false by default;
337 :     when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
338 :     will be forced to run regardless of whether or not their targets
339 :     are up-to-date
340 :     - changed installer code so that config/install.sh will re-build
341 :     heap images for all tools even if those heap images already existed

365 :     Date: 2007/05/31 14:55:00 CDT
366 :     Revision: 2650
367 :     Description:
368 :    
369 :     3rd merge of base from primop-branch-3 into the trunk.
370 :     Additional bug fixes included:
371 :    
372 :     * Timer.cpu_timer, etc. type printing corrected (by making
373 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
374 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
375 :     Stefan Monnier)

377 :     ----------------------------------------------------------------------
378 : blume 2645 Name: Matthias Blume (http://www.tti-c.org/blume/)
379 :     Date: 2007/05/31 11:40:00 CDT
380 :     Description:
381 :    
382 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
383 :    
384 :     Also, changed the handling of "no core access": When translate.sml
385 :     needs access to a core exception at a time when the core has not
386 :     been set up yet (this only happens when compiling system/smlnj/init/*),
387 :     then don't bother generating the corresponding tests.
388 :    
389 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
390 :     the exception. Unfortunately, that confuses the plambda type checker.
391 :     Moreover, it does not do any good, because at runtime we don't expect
392 :     such an exception to be ever raised. (The code in system/smlnj/init/*
393 :     has to be written very carefully with this in mind!)

405 :     Description:
406 :    
407 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
408 :     with an explicit test for zero division. This should fixes several
409 :     regressions and makes it possible for downstream optimization phases
410 :     to treat these operations as "pure" when they are applied to unsigned
411 :     operands.

435 :    
436 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
437 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
438 :    
439 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
440 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
441 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
442 :     while running CMB.make. The point is that the single symbol
443 :     NO_PLUGINS is definde in all three cases.)
444 :    
445 :     I changed the three locations within the sources that get compiled
446 :     during CMB.make where ml-yacc or ml-lex input is processed: When
447 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
448 :     is bypassed.
449 :    
450 :     When bootstrapping new versions of the compiler, there can be
451 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
452 :     are not available or otherwise not operational. In this case one can
453 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
454 :     do so, the following command should be issued at the interactive
455 :     prompt:
456 :    
457 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
458 :    
459 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
460 :     files that normally would be generated by ml-yacc and ml-lex.
461 :     (Copies of these files are in the repository.)

467 :     Description:
468 :    
469 :     2nd merge of base from primop-branch-3 into the trunk.

477 :     Description:
478 :    
479 :     Changed the installation mechanism for CM tool plugins. These are
480 :     just libaries and now get installed like ordinary libaries.
481 :    
482 :     There are now a number of new installation targets that give some
483 :     fine-grain control over what classes and suffixes are known, and what
484 :     they will map to.
485 :     See config/targets for details.
486 :    
487 :     The code that caused plugin installation as part of running a
488 :     tool's "build" script has been removed. (The build script is for
489 :     building, not for installing.)

494 :     Description:
495 :    
496 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
497 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
498 :     CM fail if a shell tool reports a non-success exit status. If
499 :     the control is set to true, then CM will press on after tool failures
500 :     in the event that the target files exist (even though they are
501 :     considered outdated). Turning the control to true can be useful for
502 :     bootstrapping.

507 :     Description:
508 :    
509 :     Merge of ml-lpt revisions for 110.64.
510 :    
511 :     The name of several ml-lpt-lib modules has changed:
512 :     Repair => AntlrRepair
513 :     StreamPos => AntlrStreamPos
514 :     ErrHandlerFn => AntlrErrHandler
515 :     EBNF => AntlrEBNF
516 :    
517 :     The ml-antlr specification format has changed: declarations such as
518 :     %tokens and nonterminal definitions can occur *multiple* times in the
519 :     same specification. The semantics are such that each new declaration
520 :     extends the previous ones. This does not apply to %start or %name,
521 :     of course.
522 :    
523 :     Importing a grammar via %import now includes *all* declarations in from
524 :     the imported grammar, except for %name, %entry, and %start. Tokens
525 :     and nonterminals can be dropped using the new %dropping clause of the
526 :     %import directive; the separate %drop and %extend have been removed.
527 :    
528 :     We now allow optional type annotations on nonterminals, using the %nonterms
529 :     directive as in ml-yacc.
530 :    
531 :     The refcell construct is now implemented using SML's regular reference
532 :     cells, so the :== and !! notation has been deprecated.
533 :    
534 :     The ml-antlr tool now does much more checking of specifications, and
535 :     its error messages have been greatly improved. Error repair for
536 :     generated parsers has been completely rewritten, and is now both
537 :     much faster and more accurate.
538 :    
539 :     ml-ulex is now more lenient with escape codes (non-SML-standard
540 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
541 :     Also, character classes may now include a "-" character at the beginning
542 :     as is standard in most other regexp tools.
543 :    
544 :     All of these changes are documented in the user guide, which has
545 :     been updated and improved with this merge.

613 :    
614 :     More Basis fixes: The Char.fromString (etc.) functions did not handle

695 :     Date: 2007/02/26
696 :     Description:
697 :    
698 :     Added preliminary support in MLRISC for Staged Allocation, a technique
699 :     for specifying calling conventions (see
700 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
701 :     Initially, we plan to use this code to generate C calls for the AMD64.
702 :    
703 :     The staged allocation code base resides in MLRISC/staged-allocation,
704 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

724 :    
725 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
726 :     of the range -128 ... 127. I've changed the code so that the range
727 :     check is disabled. Only the low order 8 bits of the immediate operand

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

782 : blume 2298 Date: 2007/02/01 10:05:00 CST
783 :     Description:
784 :    
785 :     Implemented library installer. Moved CM plugin code for
786 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
787 :     their respective trees. Implemented CM plugin for ml-ulex
788 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
789 :     and ml-antlr.
790 :    
791 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
792 :     CM tools. (It turns out to be too messy to do otherwise because
793 :     there is too much code that during installation relies on the presence
794 :     of these tools -- resulting in a tricky ordering problem.)

798 : blume 2277 Date: 2007/01/30 11:05:00 CST
799 :     Description:
800 :    
801 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
802 :     Modified CM's startup code to use shiftArgs as it processes
803 :     command line arguments. This way, the init code in each .sml-file
804 :     or library that is mentioned at the top level will see only
805 :     those arguments that have not yet been processed at this point.
806 :     In other words, the init code can "seize control" and process the
807 :     remaining command line.

866 :     get the c_cc termios data copied correctly. Also moved the allocation
867 :     of the string to avoid problems if it caused a GC.
868 :    
869 :     Thanks to Timothy Bourke for the bug report and fix.

874 :     Description:
875 :    
876 :     Added code to CM's "standard shell tool" implementation which
877 :     causes it to tolerate (with a warning) the situation where the shell
878 :     command fails (e.g., due to the shell command's non-existence)
879 :     as long as all target files exist.
880 :    
881 :     This makes it possible to, e.g., build ml-yacc from sources even if
882 :     svn checkout messed up the time stamps on files in such a way that
883 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
884 :     be needed to re-process yacc.grm, but obviously it might not yet be
885 :     available at that time.)

924 :     Tag: release-110.60
925 :     Description:
926 :    
927 :     New working release (110.60). NEW BOOTFILES!
928 :    
929 :     This is the first subversion-hosted release. There are also changes
930 :     to the directory layout. Here is a table:
931 :    
932 :     (All pathnames are relative to the SML/NJ "root" directory.)
933 :    
934 :     config -> config
935 :    
936 :     src/cm -> base/cm
937 :     src/compiler -> base/compiler
938 :     src/runtime -> base/runtime
939 :     src/system -> base/system
940 :    
941 :     src/cm/pgraph -> pgraph
942 :    
943 :     src/READMES -> base/READMES
944 :     src/$notefile -> base/NOTES/$notefile
945 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
946 :     MACOSXINSTALL WININSTALL
947 :    
948 :     src/smlnj-lib -> smlnj-lib
949 :     src/MLRISC -> MLRISC
950 :     ckit -> ckit
951 :     src/cml -> cml
952 :     src/eXene -> eXene
953 :     src/heap2asm -> heap2asm
954 :     src/lexgen -> lexgen
955 :     src/ml-burg -> ml-burg
956 :     src/ml-lex -> ml-lex
957 :     src/ml-yacc -> ml-yacc
958 :     src/ml-nlffi-lib -> nlffi/lib
959 :     src/ml-nlffigen -> nlffi/gen
960 :     src/smlnj-c -> smlnj-c
961 :     src/tools/TraceDebugProf -> trace-debug-profile
962 :    
963 :     In addition, there is also a new
964 :    
965 :     ml-lpt
966 :    
967 :     directory containing two new program generator tools: ml-ulex and
968 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
969 :     LL(k) parser generator). These tools are currently "beta-quality"
970 :    
971 :     The latest versios of the sources can now be obtained anonymously
972 :     via subversion. For this, it is useful to first check out
973 :    
974 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
975 :    
976 :     and put the resulting directory on your shell's PATH. This provides
977 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
978 :     and refresh-all.sh.
979 :    
980 :     To create a freshly checked-out copy of the sources, do
981 :    
982 :     checkout-all.sh [dir]
983 :    
984 :     where dir is the optional SML/NJ root directory (default is ".").
985 :    
986 :     This creates the above directory layout. Each subdirectory of
987 :     the root is under individual subversion control. The stat-all.sh
988 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
989 :     each of these subtrees.
990 :

992 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
993 : blume 2155 Date: 2006/11/02 12:20:00 CST
994 :     Description:
995 :    
996 :     Reorganized directory layout.
997 :    
998 :     This is a temporary solution, more reorganization is to come.
999 :    
1000 :     The basic idea is to have a number of toplevel trees, each corresponding
1001 :     to a well-defined part of the overall system. Each part can be
1002 :     maintained individually, even in separate source repositories,
1003 :     although currently we still serve everything out of the main
1004 :     smlnj-gforge tree.
1005 :    
1006 :     Installer and and scripts have been updated to reflect the new
1007 :     layout. The installer (base/src/system/smlnj/installer) is now
1008 :     "scriptable" to avoid burning too much knowledge about the
1009 :     layout into SML source code. The main script used by the installer
1010 :     is in config/actions.
1011 :    
1012 :     The main change is that many of the subdirectories of what used to
1013 :     be known as "src" have moved to the toplevel. The "src" directory
1014 :     itself has moved down into a subtree called "base". (We may eventually
1015 :     get rid of the extra level of indirection represented by "src".)
1016 :    
1017 :     The layout is now as follows:
1018 :    
1019 :     toplevel tree name | default repository
1020 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1021 :     -------------------+----------------------------------------------------
1022 :     config | $gf/config/trunk
1023 :     |
1024 :     base | $gf/sml/trunk
1025 :     |
1026 :     smlnj-lib | $gf/smlnj-lib/trunk
1027 :     MLRISC | $gf/MLRISC/trunk
1028 :     |
1029 :     ml-yacc | $gf/ml-yacc/trunk
1030 :     ml-lex | $gf/ml-lex/trunk
1031 :     ml-burg | $gf/ml-burg/trunk
1032 :     lexgen | $gf/lexgen/trunk
1033 :     heap2asm | $gf/heap2asm/trunk
1034 :     |
1035 :     cml | $gf/cml/trunk
1036 :     eXene | $gf/eXene/trunk
1037 :     ckit | $gf/ckit/trunk
1038 :     nlffi | $gf/nlffi/trunk
1039 :     |
1040 :     smlnj-c | $gf/smlnj-c/trunk
1041 :    
1042 :     In $gf/admin there are a few useful shell scripts for checking out
1043 :     and maintaining the entire collection of trees:
1044 :    
1045 :     admin/checkout-all.sh [dir]
1046 :     -- optionally creates dir and checks out all trees from their
1047 :     default repositories; if dir is missing, checkout into .
1048 :     admin/refresh-all.sh [dir]
1049 :     -- looks at all trees (from the above list) in dir (default: .)
1050 :     and runs "svn update" if the tree exists and is under
1051 :     subversion control;
1052 :     non-existing or non-subversion trees are skipped
1053 :     admin/stat-all.sh [dir]
1054 :     -- like refresh-all.sh, but runs "svn stat" instead

1235 :    
1236 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1237 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1238 : blume 2155 at the time when config/preloads is processed, the library has to
1239 : mblume 1878 be referred to by another name. In 110.57 this would be
1240 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1241 :     to be valid as well.)

1296 :     Tag: blume-22051115-versiontool
1297 :     Description:
1298 :    
1299 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1300 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1301 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1302 :     it. Instead, it has the status of "user code", so it should use
1303 :     $/basis.cm to refer to the Basis library. (At least that's true for
1304 :     the purpose of bootstrapping the previous change. In the future it
1305 :     might make sense to have versiontool.cm refer to
1306 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1307 :     compiler itself uses.)
1308 :    
1309 :     Also patched src/system/testml to have it activate those extra anchor
1310 :     bindings in config/extrapathconfig.

1315 :     Tag: blume-22051115-libraries
1316 :     Description:
1317 :    
1318 :     This change affects the way the following libraries are tied into
1319 :     the system:
1320 :    
1321 :     $/basis.cm
1322 :     $/smlnj-lib.cm
1323 :     $/pp-lib.cm
1324 :     $/controls-lib.cm
1325 :     $/html-lib.cm
1326 :     $/ml-yacc-lib.cm
1327 :    
1328 :     These libraries are now internally (as seen from the source code
1329 :     of the implementation itself) known by the following names:
1330 :    
1331 :     $smlnj/basis/basis.cm
1332 :     $smlnj/smlnj-lib/smlnj-lib.cm
1333 :     $smlnj/smlnj-lib/pp-lib.cm
1334 :     $smlnj/smlnj-lib/controls-lib.cm
1335 :     $smlnj/smlnj-lib/html-lib.cm
1336 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1337 :    
1338 :     This makes it possible to work with code that requires different
1339 :     versions of these libraries, and which refers to these libraries using
1340 :     their "default" names (i.e., the first set of names above). In other
1341 :     words, one can un-define or re-define those default names without
1342 :     compromising the proper functioning of the compiler itself.
1343 :    
1344 :     A similar procedure had already been performed for several of the
1345 :     MLRISC libraries that are linked into the compiler. I did some
1346 :     cleanup on this code.
1347 :    
1348 :     A new file in the config directory (named extrapathconfig) is
1349 :     responsible for setting up path anchors that the compiler itself does
1350 :     not need, but that are typically required by user code.

1360 :     out the problem.)

1529 :     Tag: blume-20050516-redump-heap
1530 :     Description:
1531 :    
1532 :     Added mechanism for re-creating a heap file for the interactive system
1533 :     after configuration variables have been changed.
1534 :    
1535 :     CM.redump_heap : string -> unit
1536 :    
1537 :     This is much like SMLofNJ.exportML, but starting from the resulting
1538 : blume 2155 heap does not return to the caller of CM.redump_heap but
1539 : mblume 1792 restarts the interactive system from scratch. The original call of
1540 :     CM.redump_heap does not return but ends the interactive session.
1541 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1542 :    
1543 :     Internally, redump_heap winds the dynamic execution context back to
1544 :     the point where the original heap image was created and re-executes
1545 :     the heap image generation code in the boot code.

1661 :     Tag: blume-20050114-heap2exec
1662 :     Description:
1663 :    
1664 :     Implemented new (but still experimental) heap2exec facility. This is
1665 :     tested under Mac OS X and should work under Linux (will test shortly).
1666 :     It will probably also work on the Sparc (will test some time later).
1667 :    
1668 :     - removed old "HACKED_STANDALONE" hack from runtime
1669 :    
1670 :     To be able to test this, uncomment the request for "heap2asm" in
1671 :     config/targets prior to installation. (Notice that this is different
1672 :     from "heap2exec" mentioned below. Not a typo.)
1673 :    
1674 :     To perform an actual test, run the command
1675 :    
1676 :     $ bin/heap2exec heapfile execfile
1677 :    
1678 :     (You can put heap2exec on your shell's path.)

1680 :     For example, run
1681 :    
1682 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1683 :    
1684 :     This will create a standalone executable called "mly" which you can
1685 :     then invoke directly as a command.

1830 :     Tag: blume-20041124-position
1831 :     Description:
1832 :    
1833 :     The compiler can now be compiled in a mode that makes structure Position
1834 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1835 :     for the time being.
1836 :    
1837 :     To enable 64-bit positions, use the following procedure:
1838 :    
1839 :     1. Start sml
1840 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1841 :     3. Type
1842 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1843 :     4. Run CMB.make() as usual.
1844 :    
1845 :     This is barely tested. The only test so far was a little SML program
1846 :     counting the number of characters in an 8-gigabyte file by
1847 :     reading it character-by-character. That test was successful.
1848 :    
1849 :     In support of 64-bit positions, a number of new functions have been
1850 :     added to the runtime system.

1895 :    
1896 :     - In a previous commit, fixed a minor issue with how polyequal is being
1897 :     translated. In particular, the code now "looks through" abstractions.
1898 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1899 :     more efficient code. Important examples for where this matters are
1900 :     the new int64 and word64 types.

1917 :     All the pieces of Word64 are now there, with the exception of the
1918 :     conversions from and to LargeWord. (Eventually these need to be identities,
1919 :     but for the time being they don't even make sense because LargeWord is
1920 :     32-bit wide.)
1921 :    
1922 :     Also started to add similar support for Int64, but major pieces of that
1923 :     are still missing.

1928 :     Tag: blume-20041111-word64
1929 :     Description:
1930 :    
1931 :     Structure Word64 is now (almost) complete, word literals and patterns
1932 :     seem to work. There are a few odd pieces missing. In particular,
1933 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1934 :     at the moment.
1935 :    
1936 :     Making Word64 official would mean that LargeWord becomes Word64. But
1937 :     this requires extreme care because most word-word conversions have to
1938 :     go through LargeWord, so making a mistake means loss of efficiency or
1939 :     worse. Eventually there will be a solution similar to (but actually
1940 :     simpler than) what I did with IntInf.

1977 :     normally does not have to be edited to reflect a version change.
1978 :    
1979 :     (As a result, a version change can be done by just editing

2020 :     Tag: blume-20041020-standalone-backtrace
2021 :     Description:
2022 :    
2023 :     Added a mechanism for getting back-trace information from standalone
2024 :     programs. Here is how it works:
2025 :    
2026 :     1. The part of the program from which you want to get backtrace
2027 :     information (usually the whole program) should be wrapped with
2028 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
2029 :     main program could be modified from something like
2030 :    
2031 :     fun main (pgm, args) = ...
2032 :    
2033 :     to
2034 :    
2035 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2036 :    
2037 :     2. To be able to access BackTrace.monitor, you have to add
2038 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
2039 :     main function.
2040 :    
2041 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2042 :     CM might have created in the past for your project).
2043 :    
2044 :     4. Build the system using this command line:
2045 :    
2046 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2047 :     myprog.cm MyProg.main myprog
2048 :    
2049 :     instead of the usual
2050 :    
2051 :     ml-build myprog.cm MyProg.main myprog
2052 :    
2053 :     I changed a library name:
2054 :    
2055 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2056 :    
2057 :     New libraries:
2058 :    
2059 :     $smlnj-tdp/back-trace.cm
2060 :     -- when loaded causes the back-trace plugin to be installed
2061 :     $smlnj-tdp/coverage.cm
2062 :     -- when loaded causes the coverage plugin to be installed

2086 :     - only the instrumentation mechanism is now left in the compiler proper
2087 :     - BackTrace module is a plugin which is NOT plugged in by default
2088 :     - Coverage module is another such plugin
2089 :    
2090 :     To get the benefits of any of these plugin modules, the code in
2091 :     question must be compiled with tdp instrumentation turned on. This
2092 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2093 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2094 :    
2095 :     Plugins are selected at link time. (Pre-compiled instrumented code
2096 :     can be re-loaded with different plugins in effect.) When an
2097 :     instrumented module is linked, whatever plugins are at that time
2098 :     enabled will come into effect for that module.
2099 :    
2100 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2101 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2102 :     To enable the coverage plugin, load the same library and invoke
2103 :     Coverage.install().
2104 :    
2105 :     Back-traces are generated automatically on uncaught exceptions and
2106 :     when the code in question explicitly invokes BackTrace.trigger().
2107 :    
2108 :     Coverage (and execution frequency-) information must be queried
2109 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2134 :    
2135 :     The control flag controlling whether instrumentation is on or off is now

2163 :    
2164 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool
2165 :     is supposed to accept a tool argument called "source", but this did
2166 :     not work because of the clash with the keyword.

2210 :    
2211 :     * Moved the "version" magic into its own little library under

2217 : mblume 1639
2218 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2219 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2220 :     Also, loading the versiontool does not work when rebuilding the system
2221 :     because CM is not properly initialized at that time.

2226 :     Tag: blume-20040929-autoversion
2227 :     Description:
2228 :    
2229 :     Implemented some CM magic to have
2230 :     file src/compiler/TopLevel/main/version.sml
2231 :     generated automagically.
2232 :     The version is taken from two files: config/version and config/release.
2233 :     The first is expected to contain a two-part version number such as 110.49.
2234 :     The second should contain a single number, but it may be missing.
2235 :    
2236 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2237 :     time the version tool is loaded (which is the first time you say CMB.make),
2238 :     then the tool will increment the value stored in config/release every
2239 :     time CMB.make is invoked.
2240 :    
2241 :     The binfile format is now insensitive to anything beyond the first
2242 :     two components of a version number, so bumping the release does not render
2243 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2244 :     during development without invalidating existing binfiles.
2245 :    
2246 :     In any case, every CMB.make updates the date information in version.sml.
2247 :     (This is the date that is printed in the banner.)

2260 :     Tag: blume-20040927-controls
2261 :     Description:
2262 :    
2263 :     Added two pieces of functionality to the Controls interface:
2264 :    
2265 :     1. val save'restore: 'a control -> unit -> unit
2266 :    
2267 :     grabs the current value of the control in stage 1 and restores it
2268 :     in stage 2.
2269 :    
2270 :     2. val set' : 'a control * 'a -> unit -> unit
2271 :    
2272 :     stores the given value into the control in stage 2 (i.e., delayed)
2273 :     but does all error checking in stage 1.
2274 :     (This is for string controls that need to do parse their argument --
2275 :     something that might fail. In some cases, notably in CM, one
2276 :     already knows the intended argument but wants to delay the actual
2277 :     assignment until a time when error recovery would be more difficult.)
2278 :    
2279 :     Changed the handling of controls in tool arguments to classes "sml" and
2280 :     "lazysml":
2281 :     - use Controls.save'restore as a more robust way of restoring the
2282 :     old value (in particular: without having to re-parse the string)
2283 :     - use controls to handle the "overload" keyword in the init group
2284 :     (I believe this change actually fixes a long-standing obscure bug.)

2289 :     Tag: blume-20040927-lazysml
2290 :     Description:
2291 :    
2292 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2293 :     difference to "sml" is that compilation is done with Control.lazysml
2294 :     set to true. A source of class "lazysml" is automatically recognized
2295 :     by a file name suffix of ".lml".
2296 :    
2297 :     In addition to the above feature, the original class "sml" now also
2298 :     supports a tool argument "lazy" which has the same effect. As a
2299 :     result, the following three lines are equivalent:
2300 :    
2301 :     foo.sml : lazysml
2302 :     foo.sml : sml (lazy)
2303 :     foo.sml (lazy)
2304 :    
2305 :     The setting goes into effect both during parsing and during
2306 :     compilation. The original setting is restored right after parsing and
2307 :     after compilation, respectively.
2308 :    
2309 :     In addition to all the above, there is also a general mechanism to set
2310 :     ANY of the "controls" that are available at the command line via
2311 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2312 :     apply as well. (In fact, "lazy" is implemented as a special case of
2313 :     the general mechanism.)
2314 :    
2315 :     The .cm file syntax uses a new keyword tool argument called "with".
2316 :     There are several ways of indicating the desired settings:
2317 :    
2318 :     foo.sml (with:parser.quotations=true)
2319 :     foo.sml (with:(name:parser.quotations value:true))
2320 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2321 :     foo.sml (with:(name1=value1 name2=value2 ...))
2322 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2323 :    
2324 :     etc.
2325 :    
2326 :     Another possible abbreviation is to leave out the =v or value:v part
2327 :     if the name refers to a boolean control (in which case the value is
2328 :     taken to be true). Thus, one could get lazy sml also by saying:
2329 :    
2330 :     foo.sml (with:parser.lazy-keyword=true)
2331 :     foo.sml (with:parser.lazy-keyword)
2332 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2333 :     foo.sml (with:(name:parser.lazy-keyword))

2685 :     Description:
2686 :    
2687 :     Changed the interface of structures Timer and Unix to match the most
2688 :     recent Basis spec.
2689 :    
2690 :     In the case of Unix there still seems to be an open/weird issue:
2691 :    
2692 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2693 :     fresh streams whenever they are called -- as opposed to have them
2694 :     return the same stream every time. This design is supposed to
2695 :     prevent space leaks caused by proc values hanging on to streams.
2696 :    
2697 :     The reap function, on the other hand, is supposed to close the
2698 :     streams. This cannot be done without having a handle on the
2699 :     stream in proc after all...
2700 :    
2701 :     I took the liberty to implement the following stopgap solution:
2702 :    
2703 :     The proc value hangs on to the most recently created stream(s).
2704 :     Reap closes those. If either or both of the two streams hadn't
2705 :     been created at all yet, then reap will close the corresponding
2706 :     file descriptors directly.
2707 :    
2708 :     PS: I don't understand the original space leak argument anymore. If
2709 :     a proc hangs on to the imperative stream, then I/O operations on those
2710 :     will advance the state of the cached stream and avoid the space leak.

2724 :     Description:
2725 :    
2726 :     CM now ignores (but still accepts) the "owner" information in group
2727 :     descriptions. The owner of a group is its next enclosing
2728 :     library. Each group must have a unique owner. (There is a virtual
2729 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2730 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2731 :     and CM would check that such a declaration is correct. The new scheme
2732 :     is to have CM check that for each group there is precisely one owning
2733 :     library.
2734 :    
2735 :     The advantage of the new scheme is that the programmer no longer needs
2736 :     to maintain the somewhat annoying owner information. The downside is
2737 :     that CM cannot enforce the ownership rule across multiple runs of
2738 :     CM.make. Fortunately, enclosing the same group in two different
2739 :     libraries A and B which are not part of the same program does not
2740 :     cause real problems.

2760 :    
2761 :     Arranged for ml-build to clean up after itself a little bit better.
2762 :     The script generates a temporary SML source file and compiles it using
2763 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
2764 :     gets rid of those at the end, so they don't accumulate under .cm.
2765 :    
2766 :     This required a minor change to install.sh because the name of the

2787 :     for the voluminous patch!
2788 :    
2789 :     (I have not tested this patch under win32 yet.)
2790 :    
2791 : mblume 1490 Here is David's e-mail:
2792 :    
2793 :     Hi,
2794 :    
2795 :     Attached to this email you find a diff against sml/nj 110.45
2796 :     that will enable socket support under Windows.
2797 :    
2798 :     To apply the patch (using unix or cygwin)
2799 :     1) gunzip runtime.diff.gz
2800 :     2) "cd" into "src/runtime" in the source tree of a fresh
2801 :     110.45 installation.
2802 :     3) patch -p 1 < [your/path/to]runtime.diff
2803 :    
2804 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2805 :     I only ran a few tests for basic socket client functionality
2806 :     (which worked fine). Especially the functions that use ioctl
2807 : mblume 1490 are not tested at all and might not work (see below).
2808 :    
2809 :     I implemented this since we want to move to a newer version of sml/nj
2810 :     but need socket support in order to use it. This is the first time I
2811 :     even had a look at the sml/nj source, so please review my changes
2812 :     before making this part of the distribution! Here are a few issues
2813 : blume 2155 that I think might be better for someone to solve who is more
2814 : mblume 1490 familiar with the sml/nj source (and socket programming):
2815 :    
2816 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2817 :     exception since I could not figure out what the windows equivalent
2818 :     of these functions is
2819 :    
2820 :     - In sockets-osdep.h there are a some #include statements that are
2821 :     only used in a few files that include sockets-osdep.h
2822 :    
2823 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2824 :     does not process its return value since I don't know how to
2825 :     report an error upwards.
2826 :    
2827 :     - It would probably be good to have a call to WSACleanup() when
2828 : blume 2155 the library is unloaded (if there is such a possibility).
2829 : mblume 1490 Otherwise I think Windows will take care of this automatically
2830 :     when the process finishes.
2831 :    
2832 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2833 :     no idea if that is actually the proper replacement on Windows.
2834 :    
2835 :     - All these issues are marked in the code by "FIXME" comments.
2836 :    
2837 : blume 2155 We use sml/nj extensively in our products and are quite happy
2838 :     with it. I hope this contribution will help you.
2839 : mblume 1490
2840 :     Keep up the good work!

2879 :     the installer knows about". In other words, if you enable "src-smlnj"
2880 :     in the "targets" file, then the installer will pull in sources for
2881 :     everything. (Notice that this refers to source code only. Compiled
2882 :     code is still only installed for modules that were requested explicitly
2883 :     or which are required for other modules that were requested explicitly.)

2917 :     Description:
2918 :    
2919 :     Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
2920 :     of SML/NJ. The problem is that
2921 :    
2922 :     lib = dlopen(NULL, ...)
2923 :     f = dlsym(lib, "malloc");
2924 :    
2925 : blume 2155 does not work on Windows unless we explicitly export symbols
2926 :     such as 'malloc' during linking. We fixed this by explicitly
2927 : allenleung 1468 exporting the required symbols with the magic gcc incantation:
2928 :    
2929 :     -Wl,--export-all cygwin.def
2930 :    
2931 :     where cygwin.def is a file containing all the symbols that
2932 : blume 2155 we wish to export.
2933 : allenleung 1468
2934 : blume 2155 I suspect this is a Windows problem and we'll have to
2935 :     do the same (somehow with windows compilers) when
2936 : allenleung 1468 we build the native win32 version with the system
2937 : blume 2155 calls LoadLibrary/GetProcAddress.

3009 :     there does not seem to be any reason not to move all libraries into

3062 :     Tag: blume-20030926-ppautoload
3063 :     Description:
3064 :    
3065 :     I modified the read-eval-print loop so that the autoloader gets
3066 :     invoked whenever the prettyprinter tries to look up a symbol that
3067 :     is not currently defined in the toplevel environment but which
3068 :     appears in CM's autoload registry. As a result, we see far fewer of
3069 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3070 :    
3071 :     In addition to this I tried to clean up some pieces of the Basis
3072 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3073 :     instances of these ?.Foo.Bar.xxx names from being printed.
3074 :    
3075 :     The mechanism that picks names for types still needs some work, though.
3076 :     (Right now it seems that if there is a type A.t which is defined to
3077 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3078 :     "?.B.u" although the perhaps more sensible solution would be to use
3079 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3080 :     a chain of DEFtycs not farther than there are corresponding toplevel
3081 :     names in the current environment.)

3087 :     Description:
3088 :    
3089 :     Another installer tweak: All the ML code for the installer is now
3090 :     compiled during CMB.make and put into a little library called
3091 :     $smlnj/installer.cm. The installation then simply invokes
3092 :    
3093 :     sml -m $smlnj/installer.cm
3094 :    
3095 :     and everything happens automagically.
3096 :    
3097 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3098 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3099 :     and BINDIR.
3100 :    
3101 :     The new scheme guarantees that the ML code responsible for the installation
3102 :     is in sync with the APIs of the main system. Also, the installer is
3103 :     somewhat faster because the installer script is precompiled.

3120 :     Tag: blume-20030924-sockets
3121 :     Description:
3122 :    
3123 :     1. Fixed SOCKET API and implementation to match Basis spec.
3124 :     This required changing the internal representation of sockets to one
3125 :     that remembers (for each socket file descriptor) whether it is currently
3126 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3127 :     call is made only if the state actually needs to change).
3128 :    
3129 :     2. OS-specific details of sockets were moved into separate files, thus
3130 :     making it possible to unify the bulk of the socket implementations
3131 :     between Unix and Win32.
3132 :    
3133 :     3. CML's socket API changed accordingly.
3134 :     (Note that we need to remove non-blocking functions from this API
3135 :     since they are redundant in the case of CML!)
3136 :    
3137 :     4. CML's socket implementation now makes use of non-blocking functions
3138 :     provided by Basis, thus removing all OS-dependent code from this part
3139 :     of CML.
3140 :    
3141 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3254 :     Description:
3255 :    
3256 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3257 :     Modified config/install.bat to take advantage of it. Also modified
3258 :     config/install.sh (and called it config/new-install.sh) to take advantage
3259 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3260 :     independent.)
3261 :    
3262 :     The installer can now install everything under Win32

3264 :    
3265 :     Other changes:
3266 :    
3267 :     - made CML compile again under Win32
3268 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3269 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3270 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3271 :     same as type int; under Win32 it isn't
3272 :     - fixed some slice-related problems in the win32-specific parts of CML
3273 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3274 :     (under Win32, the volume name is case-insensitive, and the
3275 :     OS.Path code compares volume names for equality)

3291 : mblume 1352 Tag: blume-20030905-slices-etc
3292 : mblume 1350 Description:
3293 :    
3294 :     1. Changed interface to vectors and arrays in Basis to match
3295 :     (draft) Basis spec.
3296 :     2. Added signatures and implementations of slices according to
3297 :     Basis spec.
3298 :     3. Edited source code throughout the system to make it compile again
3299 :     under 1. and 2. (In some cases code had to be added to have it
3300 :     match the new signatures.)
3301 :     4. MLRISC should be backward-compatible: the copies of the originals
3302 :     of files that needed to change under 3. were retained, the .cm files
3303 :     check the compiler version number and use old versions when
3304 :     appropriate.
3305 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3306 :     dirstream -> string option (in accordance with Basis spec).
3307 :     6. When generating code that counts lines, ml-lex used function
3308 :     CharVector.foldli, taking advantage of its old interface.
3309 :     This has been replaced with the corresponding code from
3310 :     CharVectorSlice. (html-lex must be re-lexed!)
3311 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3312 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3313 :     8. Removed temporary additions (fromInternal, toInternal) from the
3314 :     (now obsolete) IntInf in smlnj-lib/Util.
3315 :     9. Cleaned up structure Byte.
3316 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3317 :     Cleaned/corrected implementation of Date.
3318 :     (Still need to check for correctness; implement better canonicalizeDate.)
3319 :     11. Added "scan" to signature IEEE_REAL.
3320 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3321 :     mod and rem when second operand is 2 (for parity checks).]
3322 :     13. Changed representation of type Time.time, using a single IntInf.int
3323 :     value counting microseconds. This considerably simplified the
3324 :     implementation of structure Time. We now support negative time
3325 :     values; scan and fromString handle signs.
3326 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3327 :     ArraySlice).

3332 :     Tag: blume-20030828-intinf
3333 :     Description:
3334 :    
3335 :     This is a major update which comes with a version number bump
3336 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3337 :     and an implementation of IntInf in the Basis.
3338 :    
3339 :     There are a fairly large number of related changes and updates throughout
3340 :     the system:
3341 :    
3342 :     Basis:
3343 :     - Implemented IntInf.
3344 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3345 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3346 : mblume 1347 - Added FixedInt as a synonym for Int32.
3347 :    
3348 :     compiler:
3349 :     * Added support for a built-in intinf type.
3350 :     - literals
3351 :     - pattern matching
3352 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3353 :     - overloading on literals and operations
3354 :    
3355 :     This required adding a primitive type intinf, some additional
3356 :     primops, and implementations for several non-trivial intinf
3357 :     operations in Core. (The intinf type is completely abstract
3358 :     to the compiler; all operations get delegated back to the Core.)
3359 :    
3360 :     * Intinf equality is handled by polyequal. However, the compiler
3361 :     does not print its usual warning in this case (since polyequal
3362 :     is the right thing to do there).
3363 :    
3364 :     * Improved the organization of structure InlineT.
3365 :    
3366 :     * A word about conversion primops:
3367 :     If conversions involving intinf do not cancel out during
3368 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3369 : mblume 1347 Since all core access must be resolved already during the FLINT
3370 :     translate phase, it would be too late a the time of CPS contract
3371 : mblume 1348 to add new Core calls. For this reason, conversion primops
3372 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3373 :     they are supposed to convert, and 2. the Core function that
3374 :     can help with this conversion if necessary. If CPS contract
3375 : mblume 1348 eliminates a primop, then the associated Core function becomes
3376 :     dead and goes away. Intinf conversion primops that do not get
3377 :     eliminated by CPS contract get rewritten into calls of their
3378 :     core functions by a separate, new phase.
3379 : mblume 1347
3380 :     interactive system:
3381 :     - Control.Print.intinfDepth controls max length of intinf constants
3382 :     being printed. (Analogous to Control.Print.stringDepth.)
3383 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3384 :     duplicates; replaced some of the code with code that makes better
3385 :     use of library functionality.
3386 :    
3387 :     CM:
3388 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3389 :     are no longer silent.
3390 :    
3391 :     CKIT:
3392 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3393 :     in favor of LargeInt -- which is now the same as IntInf.
3394 :     CKIT-knowledgable people should check whether this is what's
3395 :     intended and otherwise change things back to using Int32 or
3396 :     FixedInt.
3397 :    
3398 :     Throughout the code:
3399 : mblume 1348 Started using IntInf.int literals and built-in operations
3400 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3410 :     These changes involve replacement of the emulated old prettyprinter

3419 :     Tag: blume-20030811-windows
3420 :     Description:
3421 :    
3422 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3423 :    
3424 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3425 :    
3426 :     This patch restores SML/NJ's ability to run under win32. There are a
3427 :     number of changes, including fixes for several bugs that had gone
3428 :     unnoticed until now:
3429 :    
3430 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3431 :     trying to run the win32 version from within cygwin.)
3432 :    
3433 :     - There are a number of simple .bat scripts that substitute for their
3434 :     corresponding Unix shell-scripts. (See below.)
3435 :    
3436 :     - The internals of ml-build have been modified slightly. The main
3437 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3438 :     using OS.Process.system, the ML process delegates this task back
3439 :     to the script. Otherwise problems arise in mixed environments such
3440 :     as Cygwin where scripts look and work like Unix scripts, but
3441 :     where OS.Process.system cannot run them.
3442 :    
3443 :     - In CM, the srcpath pickler used native pathname syntax -- which
3444 :     is incorrect in the case of cross-compilation. The new pickle format
3445 :     is independent of platform-specific naming conventions.
3446 :    
3447 :     - Path configuration files (such as lib/pathconfig) can now choose
3448 :     between native and standard syntax. Placing a line of the form
3449 :    
3450 :     standard!
3451 :    
3452 :     into the file causes all subsequent paths to be interpreted using
3453 :     CM standard pathname syntax (= Unix conventions); a line
3454 :    
3455 :     native!
3456 :    
3457 :     switches back to native style. This was needed so that
3458 :     path config files can be written portably, see src/system/pathconfig.
3459 :    
3460 :     - Runtime system:
3461 :    
3462 :     - win32-filesys.c: get_file_time and set_file_time now
3463 :     access modification time, not creation time.
3464 :    
3465 :     - I/O code made aware of new array representation.
3466 :    
3467 :     - Bug fixes in X86.prim.masm.
3468 :    
3469 :     - src/system/makeml made aware of win32. (For use under cygwin
3470 :     and other Unix-environments for windows.)
3471 :    
3472 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3473 :     which caused BinIO.inputAll to fail consistently.
3474 :    
3475 :     .bat scripts:
3476 :    
3477 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3478 :    
3479 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3480 :     applications (sml, ml-yacc, ml-lex).
3481 :     - ml-build.bat: analogous to ml-build.
3482 :     - config\install.bat: Analogous to config/install.sh. This requires
3483 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3484 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3485 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3486 :     and the bootfile hierarchy must have been unpacked under
3487 :     sml.boot.x86-win32.
3488 :     The script is very primitive and does a poor job at error checking.
3489 :     It only installs the base system, ml-lex, and ml-yacc. No other
3490 :     libraries are being installed (i.e., you get only those that
3491 :     are part of the compiler.)
3492 :     - link-sml.bat: analogous to .link-sml, but not currently used
3493 :    
3494 :     Unrelated bug fixes:
3495 :    
3496 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3497 :     types.
3498 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3499 :     otherwise.)

3523 :     Description:
3524 :    
3525 :     Two changes:
3526 :    
3527 :     1. Added a flag for controlling whether non-exhaustive bindings will
3528 :     be treated as errors (default is false).
3529 :     2. Cleaned up the *entire* source tree so that CMB.make goes through
3530 :     without a single non-exhaustive match- or bind warning.

3536 :     Description:
3537 :    
3538 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3539 :    
3540 :     This mainly affects the quality of error messages. However, some
3541 :     of the code is now more straightforward than before. (Treatment of
3542 :     the above four constructs in translate.sml is much simpler than
3543 :     the "macro-expansion" that was going on before. Plus, the mach-
3544 :     compiler no longer gets invoked just to be able to compile an
3545 :     if-expression.)
3546 :    
3547 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3548 :     interactive loop.

3667 :     to be in $SMLNJ_HOME/lib/pathconfig. This way one can easily move

3670 :     (Companion commands such as ml-build and ml-makedepend also sense this
3671 :     variable.)

3724 :    
3725 :     Another small change is that ppDec tries to give more information

3727 :     broken in some mysterious way if the functor's body's signature
3728 :     has not been declared by ascription but gets inferred from the
3729 :     implementation. This needs fixing...

3829 :    
3830 :     0. John Reppy made several modifications to the SML/NJ library.
3831 :     In particular, there is a shiny new controls-lib.cm.
3832 :    
3833 :     1. Pushed new controls interface through compiler so that everything
3834 :     compiles again.
3835 :    
3836 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3837 :     SML/NJ library (so that CML compiles again).
3838 :    
3839 :     3. Modified init scripts because XXX_DEFAULT environment variables
3840 :     are no longer with us. (Boot-time initialization is now done
3841 :     using the same environment variables that are also used for
3842 :     startup-time initialization of controls.)

3848 :     Description:
3849 :    
3850 :     All pseudo-ops emitted before the first segment declaration
3851 :     such as TEXT, DATA, and BSS directives are assumed to be global
3852 :     declarations and are emitted first in the assembly file. This is
3853 :     useful in a number of situations where one has pseudo-ops that are not
3854 :     specific to any segment, and also works around the constraint that one
3855 :     cannot have client pseudo-ops in the TEXT segment.
3856 :    
3857 :     Because no segment is associated with these declarations it is
3858 :     an error to allocate any space or objects before the first segment
3859 :     directive and an exception will be raised. However, we cannot make
3860 :     this check for client pseudo-ops.
3861 :    
3862 :     These top level declarations are a field in the CFG graph_info.
3863 :     In theory you can continue to add to this field after the CFG has been
3864 :     built -- provided you know what you are doing;-)

3887 :     Description:
3888 :    
3889 :     Applied the following bugfix provided by Emden Gansner:
3890 :    
3891 :     Output is corrupted when outputSubstr is used rather than output.
3892 :    
3893 : blume 2155 The problem occurs when a substring
3894 : blume 1189
3895 :     ss = (s, dataStart, dataLen)
3896 :    
3897 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3898 :     avail bytes of s, starting at index dataStart, are copied into the
3899 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3900 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3901 :     starting this copy at index dataStart+avail in s, the current code
3902 : blume 1189 starts the copy at index avail.
3903 :    
3904 :     Fix:
3905 :     In text-io-fn.sml, change line 695 from
3906 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3907 : blume 2155 to

3924 :     Description:
3925 :    
3926 :     Added full support for div/mod/rem/quot on the x86, using the machine
3927 :     instruction's two results (without clumsily recomputing the remainder)
3928 :     directly where appropriate.
3929 :    
3930 :     Some more extensive power-of-two support was added to the x86 instruction
3931 :     selector (avoiding expensive divs, mods, and muls where they can be
3932 :     replaced with cheaper shifts and masks). However, this sort of thing
3933 :     ought to be done earlier, e.g., within the CPS optimizer so that
3934 :     all architectures benefit from it.
3935 :    
3936 :     The compiler compiles to a fixed point, but changes might be somewhat
3937 :     fragile nevertheless. Please, report any strange things that you might
3938 :     see wrt. div/mod/quot/rem...

3948 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3949 :     The problem was with quotient = 0, because that alone does not tell

3960 :    
3961 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
3962 :    
3963 :     Primops have changed. This means that the bin/boot-file formats have
3964 :     changed as well.
3965 :    
3966 :     To make sure that there is no confusion, I made a new version.
3967 :    
3968 :    
3969 :     CHANGES:
3970 :    
3971 :     * removed REMT from mltree (remainder should never overflow).
3972 :    
3973 :     * added primops to deal with divisions of all flavors to the frontend
3974 :    
3975 :     * handled these primops all the way through so they map to their respective
3976 :     MLRISC support
3977 :    
3978 :     * used these primops in the implementation of Int, Int32, Word, Word32
3979 :    
3980 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3981 :    
3982 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
3983 :    
3984 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3985 :     floating point
3986 :    
3987 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3988 :     and Real (but Real.abs maps to a separate floating-point-only primop)
3989 :    
3990 :    
3991 :     TODO items:
3992 :    
3993 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
3994 :     instructions because the machine instruction encoder cannot handle
3995 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
3996 :     REM in the first place, and REM is supported by the x86 machine coder.)
3997 :    
3998 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
3999 :     selection phase. (The two can be streamlined because the hardware
4000 :     delivers both quotient and remainder at the same time anyway.)
4001 :    
4002 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
4003 :     (Currently the behavior is inconsistent both across architectures and
4004 :     wrt. the draft Basis spec.)
4005 :    
4006 :     * Word8 should eventually be handled natively, too.
4007 :    
4008 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
4009 :     as if there currently is no execution path that could trigger it in
4010 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
4011 :     hold for things like multiplication and division.)

4016 :     Tag: blume-20020327-mlrisc-divisions
4017 :     Description:
4018 :    
4019 :     Added support for all four division operations (ML's div, mod, quot,
4020 :     and rem) to MLRISC. In the course of doing so, I also rationalized
4021 :     the naming (no more annoying switch-around of DIV and QUOT), by
4022 :     parameterizing the operation by div_rounding_mode (which can be either
4023 :     DIV_TO_ZERO or DIV_TO_NEGINF).
4024 :    
4025 :     The generic MLTreeGen functor takes care of compiling all four
4026 :     operations down to only round-to-zero div.
4027 :    
4028 :     Missing pieces:
4029 :    
4030 :     * Doing something smarter than relying on MLTreeGen on architectures
4031 :     like, e.g., the x86 where hardware division delivers both quotient and
4032 :     remainder at the same time. With this, the implementation of the
4033 :     round-to-neginf operations could be further streamlined.
4034 :    
4035 :     * Remove inlining support for div/mod/rem from the frontend and replace it
4036 :     with primops that get carried through to the backend. Do this for all
4037 :     int and word types.

4042 :     Tag: blume-20020325-divmod
4043 :     Description:
4044 :    
4045 :     I improved (hopefully without breaking them) the implementation of Int.div,
4046 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
4047 :     advantage of the following observations:
4048 :    
4049 :     Let q = x quot y r = x rem y
4050 :     d = x div y m = x mod y
4051 :    
4052 :     where "quot" is the round-to-zero version of integer division that
4053 :     hardware usually provides. Then we have:
4054 :    
4055 :     r = x - q * y where neither the * nor the - will overflow
4056 :     d = if q >= 0 orelse x = q * y then q else q - 1
4057 :     where neither the * nor the - will overflow
4058 :     m = if q >= 0 orelse r = 0 then r else r + y
4059 :     where the + will not overflow
4060 :    
4061 :     This results in substantial simplification of the generated code.
4062 :     The following table shows the number of CFG nodes and edges generated
4063 :     for
4064 :     fun f (x, y) = x OPER y
4065 :     (* with OPER \in div, mod, quot, rem *)

4088 :     Description:
4089 :    
4090 :     I did some cleanup to Allen's new primop code and
4091 :     replaced yesterday's bootfiles with new ones.
4092 :     (But they are stored in the same place.)

4106 :     Description:
4107 :    
4108 :     1. Changes to FLINT primops:
4109 :    
4110 :     (* make a call to a C-function;
4111 :     * The primop carries C function prototype information and specifies
4112 :     * which of its (ML-) arguments are floating point. C prototype
4113 :     * information is for use by the backend, ML information is for
4114 :     * use by the CPS converter. *)
4115 :     | RAW_CCALL of { c_proto: CTypes.c_proto,
4116 :     ml_args: ccall_type list,
4117 :     ml_res_opt: ccall_type option,
4118 :     reentrant : bool
4119 :     } option
4120 :     (* Allocate uninitialized storage on the heap.
4121 :     * The record is meant to hold short-lived C objects, i.e., they
4122 : blume 2155 * are not ML pointers. With the tag, the representation is
4123 : leunga 1174 * the same as RECORD with tag tag_raw32 (sz=4), or tag_fblock (sz=8)
4124 :     *)
4125 : blume 2155 | RAW_RECORD of {tag:bool,sz:int}
4126 : leunga 1174 and ccall_type = CCALL_INT32 | CCALL_REAL64 | CCALL_ML_PTR
4127 :    
4128 :     2. These CPS primops are now overloaded:
4129 :    
4130 :     rawload of {kind:numkind}
4131 :     rawstore of {kind:numkind}
4132 :    
4133 :     The one argument form is:
4134 :    
4135 :     rawload {kind} address
4136 :    
4137 :     The two argument form is:
4138 : blume 2155
4139 : leunga 1174 rawload {kind} [ml object, byte-offset]
4140 :    
4141 :     3. RAW_CCALL/RCC now takes two extra arguments:
4142 :    
4143 :     a. The first is whether the C call is reentrant, i.e., whether
4144 :     ML state should be saved and restored.
4145 :     b. The second argument is a string argument specifying the name of
4146 :     library and the C function.
4147 :    
4148 :     These things are currently not handled in the code generator, yet.
4149 :    
4150 :     4. In CProto,
4151 :    
4152 : blume 2155 An encoding type of "bool" means "ml object" and is mapped into
4153 :     C prototype of PTR. Note that "bool" is different than "string",
4154 : leunga 1174 even though "string" is also mapped into PTR, because "bool"
4155 :     is assigned an CPS type of BOGt, while "string" is assigned INT32t.
4156 :    
4157 :     5. Pickler/unpicker
4158 :    
4159 :     Changed to handle RAW_RECORD and newest RAW_CCALL
4160 :    
4161 :     6. MLRiscGen,
4162 :    
4163 :     1. Changed to handle the new rawload/rawstore/rawrecord operators.
4164 :     2. Code for handling C Calls has been moved to a new module CPSCCalls,
4165 :     in the file CodeGen/cpscompile/cps-c-calls.sml
4166 :    
4167 :     7. Added the conditional move operator
4168 :    
4169 :     condmove of branch
4170 :    
4171 : blume 2155 to cps. Generation of this is still buggy so it is currently
4172 : leunga 1174 disabled.

4178 : george 1168 Description:
4179 :    
4180 : blume 2155 Implemented the Ball-Larus branch prediction-heuristics, and
4181 : george 1168 incorporated graphical viewers for control flow graphs.
4182 :    
4183 : george 1171 Ball-Larus Heuristics:
4184 : george 1168 ---------------------
4185 :     See the file compiler/CodeGen/cpscompile/cpsBranchProb.sml.
4186 :    
4187 :     By design it uses the Dempster-Shafer theory for combining
4188 :     probabilities. For example, in the function:
4189 :    
4190 :     fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)
4191 :    
4192 :     the ball-larus heuristics predicts that the n=0 is unlikely
