348 :     Date: 2007/05/31 14:55:00 CDT
349 :     Revision: 2650
350 :     Description:
351 :    
352 :     3rd merge of base from primop-branch-3 into the trunk.
353 :     Additional bug fixes included:
354 :    
355 :     * Timer.cpu_timer, etc. type printing corrected (by making
356 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
357 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
358 :     Stefan Monnier)
359 :    
360 :     ----------------------------------------------------------------------
361 : blume 2645 Name: Matthias Blume (http://www.tti-c.org/blume/)
362 :     Date: 2007/05/31 11:40:00 CDT
363 :     Description:
364 :    
365 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
366 :    
367 :     Also, changed the handling of "no core access": When translate.sml
368 :     needs access to a core exception at a time when the core has not
369 :     been set up yet (this only happens when compiling system/smlnj/init/*),
370 :     then don't bother generating the corresponding tests.
371 :    
372 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
373 :     the exception. Unfortunately, that confuses the plambda type checker.
374 :     Moreover, it does not do any good, because at runtime we don't expect
375 :     such an exception to be ever raised. (The code in system/smlnj/init/*
376 :     has to be written very carefully with this in mind!)

387 :     Date: 2007/05/29 19:00:00 CDT
388 :     Description:
389 :    
390 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
391 :     with an explicit test for zero division. This should fixes several
392 :     regressions and makes it possible for downstream optimization phases
393 :     to treat these operations as "pure" when they are applied to unsigned
394 :     operands.

398 :     Date: 2007/05/29
399 :     Description:
400 :    
401 :     Added the new MLRISC code generator for the AMD64. This version,
402 :     in contrast to the previous one, uses SSE registers and instructions
403 :     for all floating-point computations.

408 : jhr 2613 Description:
409 :    
410 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
411 :     for bugs #1415 and #1416. We also now correctly handle format characters that
412 :     lie outside the specified set.

415 : blume 2610 Name: Matthias Blume (http://www.tti-c.org/blume/)
416 :     Date: 2007/05/23 22:30:00 CDT
417 :     Description:
418 :    
419 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
420 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
421 :    
422 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
423 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
424 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
425 :     while running CMB.make. The point is that the single symbol
426 :     NO_PLUGINS is definde in all three cases.)
427 :    
428 :     I changed the three locations within the sources that get compiled
429 :     during CMB.make where ml-yacc or ml-lex input is processed: When
430 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
431 :     is bypassed.
432 :    
433 :     When bootstrapping new versions of the compiler, there can be
434 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
435 :     are not available or otherwise not operational. In this case one can
436 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
437 :     do so, the following command should be issued at the interactive
438 :     prompt:
439 :    
440 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
441 :    
442 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
443 :     files that normally would be generated by ml-yacc and ml-lex.
444 :     (Copies of these files are in the repository.)

450 :     Description:
451 :    
452 :     2nd merge of base from primop-branch-3 into the trunk.
453 :     Additional bug fixes included:
454 :     Date.scan and Date.fromString fixed;
455 :     Overloading resolution fixed and some type printing problems corrected.

460 :     Description:
461 :    
462 :     Changed the installation mechanism for CM tool plugins. These are
463 :     just libaries and now get installed like ordinary libaries.
464 :    
465 :     There are now a number of new installation targets that give some
466 :     fine-grain control over what classes and suffixes are known, and what
467 :     they will map to.
468 :     See config/targets for details.
469 :    
470 :     The code that caused plugin installation as part of running a
471 :     tool's "build" script has been removed. (The build script is for
472 :     building, not for installing.)

477 :     Description:
478 :    
479 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
480 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
481 :     CM fail if a shell tool reports a non-success exit status. If
482 :     the control is set to true, then CM will press on after tool failures
483 :     in the event that the target files exist (even though they are
484 :     considered outdated). Turning the control to true can be useful for
485 :     bootstrapping.

490 :     Description:
491 :    
492 :     Merge of ml-lpt revisions for 110.64.
493 :    
494 :     The name of several ml-lpt-lib modules has changed:
495 :     Repair => AntlrRepair
496 :     StreamPos => AntlrStreamPos
497 :     ErrHandlerFn => AntlrErrHandler
498 :     EBNF => AntlrEBNF
499 :    
500 :     The ml-antlr specification format has changed: declarations such as
501 :     %tokens and nonterminal definitions can occur *multiple* times in the
502 :     same specification. The semantics are such that each new declaration
503 :     extends the previous ones. This does not apply to %start or %name,
504 :     of course.
505 :    
506 :     Importing a grammar via %import now includes *all* declarations in from
507 :     the imported grammar, except for %name, %entry, and %start. Tokens
508 :     and nonterminals can be dropped using the new %dropping clause of the
509 :     %import directive; the separate %drop and %extend have been removed.
510 :    
511 :     We now allow optional type annotations on nonterminals, using the %nonterms
512 :     directive as in ml-yacc.
513 :    
514 :     The refcell construct is now implemented using SML's regular reference
515 :     cells, so the :== and !! notation has been deprecated.
516 :    
517 :     The ml-antlr tool now does much more checking of specifications, and
518 :     its error messages have been greatly improved. Error repair for
519 :     generated parsers has been completely rewritten, and is now both
520 :     much faster and more accurate.
521 :    
522 :     ml-ulex is now more lenient with escape codes (non-SML-standard
523 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
524 :     Also, character classes may now include a "-" character at the beginning
525 :     as is standard in most other regexp tools.
526 :    
527 :     All of these changes are documented in the user guide, which has
528 :     been updated and improved with this merge.

678 :     Date: 2007/02/26
679 :     Description:
680 :    
681 :     Added preliminary support in MLRISC for Staged Allocation, a technique
682 :     for specifying calling conventions (see
683 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
684 :     Initially, we plan to use this code to generate C calls for the AMD64.
685 :    
686 :     The staged allocation code base resides in MLRISC/staged-allocation,
687 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

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

751 :     Date: 2007/01/31
752 :     Description:
753 :    
754 :     Brought ml-lpt manual up-to-date with the code. Many minor
755 :     improvements to the tools, and a few minor bugfixes. Prepared
756 :     ml-lpt-lib for integration with new UTF8 structure. Changed
757 :     the interface for creating streams in ml-ulex (we now support
758 :     stream creation from several kinds of sources). Overall, the
759 :     tools are now quite stable, and their interfaces are unlikely to
760 :     change in a way that would break compatibility. More work,
761 :     however, is needed in the documentation.

766 :     Description:
767 :    
768 :     Implemented library installer. Moved CM plugin code for
769 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
770 :     their respective trees. Implemented CM plugin for ml-ulex
771 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
772 :     and ml-antlr.
773 :    
774 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
775 :     CM tools. (It turns out to be too messy to do otherwise because
776 :     there is too much code that during installation relies on the presence
777 :     of these tools -- resulting in a tricky ordering problem.)

782 :     Description:
783 :    
784 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
785 :     Modified CM's startup code to use shiftArgs as it processes
786 :     command line arguments. This way, the init code in each .sml-file
787 :     or library that is mentioned at the top level will see only
788 :     those arguments that have not yet been processed at this point.
789 :     In other words, the init code can "seize control" and process the
790 :     remaining command line.

855 : blume 2232 Name: Matthias Blume (http://www.tti-c.org/blume)
856 :     Date: 2006/12/08 09:50:00 CST
857 :     Description:
858 :    
859 :     Added code to CM's "standard shell tool" implementation which
860 :     causes it to tolerate (with a warning) the situation where the shell
861 :     command fails (e.g., due to the shell command's non-existence)
862 :     as long as all target files exist.
863 :    
864 :     This makes it possible to, e.g., build ml-yacc from sources even if
865 :     svn checkout messed up the time stamps on files in such a way that
866 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
867 :     be needed to re-process yacc.grm, but obviously it might not yet be
868 :     available at that time.)

907 :     Tag: release-110.60
908 :     Description:
909 :    
910 :     New working release (110.60). NEW BOOTFILES!
911 :    
912 :     This is the first subversion-hosted release. There are also changes
913 :     to the directory layout. Here is a table:
914 :    
915 :     (All pathnames are relative to the SML/NJ "root" directory.)
916 :    
917 :     config -> config
918 :    
919 :     src/cm -> base/cm
920 :     src/compiler -> base/compiler
921 :     src/runtime -> base/runtime
922 :     src/system -> base/system
923 :    
924 :     src/cm/pgraph -> pgraph
925 :    
926 :     src/READMES -> base/READMES
927 :     src/$notefile -> base/NOTES/$notefile
928 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
929 :     MACOSXINSTALL WININSTALL
930 :    
931 :     src/smlnj-lib -> smlnj-lib
932 :     src/MLRISC -> MLRISC
933 :     ckit -> ckit
934 :     src/cml -> cml
935 :     src/eXene -> eXene
936 :     src/heap2asm -> heap2asm
937 :     src/lexgen -> lexgen
938 :     src/ml-burg -> ml-burg
939 :     src/ml-lex -> ml-lex
940 :     src/ml-yacc -> ml-yacc
941 :     src/ml-nlffi-lib -> nlffi/lib
942 :     src/ml-nlffigen -> nlffi/gen
943 :     src/smlnj-c -> smlnj-c
944 :     src/tools/TraceDebugProf -> trace-debug-profile
945 :    
946 :     In addition, there is also a new
947 :    
948 :     ml-lpt
949 :    
950 :     directory containing two new program generator tools: ml-ulex and
951 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
952 :     LL(k) parser generator). These tools are currently "beta-quality"
953 :    
954 :     The latest versios of the sources can now be obtained anonymously
955 :     via subversion. For this, it is useful to first check out
956 :    
957 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
958 :    
959 :     and put the resulting directory on your shell's PATH. This provides
960 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
961 :     and refresh-all.sh.
962 :    
963 :     To create a freshly checked-out copy of the sources, do
964 :    
965 :     checkout-all.sh [dir]
966 :    
967 :     where dir is the optional SML/NJ root directory (default is ".").
968 :    
969 :     This creates the above directory layout. Each subdirectory of
970 :     the root is under individual subversion control. The stat-all.sh
971 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
972 :     each of these subtrees.
973 :

975 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
976 : blume 2155 Date: 2006/11/02 12:20:00 CST
977 :     Description:
978 :    
979 :     Reorganized directory layout.
980 :    
981 :     This is a temporary solution, more reorganization is to come.
982 :    
983 :     The basic idea is to have a number of toplevel trees, each corresponding
984 :     to a well-defined part of the overall system. Each part can be
985 :     maintained individually, even in separate source repositories,
986 :     although currently we still serve everything out of the main
987 :     smlnj-gforge tree.
988 :    
989 :     Installer and and scripts have been updated to reflect the new
990 :     layout. The installer (base/src/system/smlnj/installer) is now
991 :     "scriptable" to avoid burning too much knowledge about the
992 :     layout into SML source code. The main script used by the installer
993 :     is in config/actions.
994 :    
995 :     The main change is that many of the subdirectories of what used to
996 :     be known as "src" have moved to the toplevel. The "src" directory
997 :     itself has moved down into a subtree called "base". (We may eventually
998 :     get rid of the extra level of indirection represented by "src".)
999 :    
1000 :     The layout is now as follows:
1001 :    
1002 :     toplevel tree name | default repository
1003 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1004 :     -------------------+----------------------------------------------------
1005 :     config | $gf/config/trunk
1006 :     |
1007 :     base | $gf/sml/trunk
1008 :     |
1009 :     smlnj-lib | $gf/smlnj-lib/trunk
1010 :     MLRISC | $gf/MLRISC/trunk
1011 :     |
1012 :     ml-yacc | $gf/ml-yacc/trunk
1013 :     ml-lex | $gf/ml-lex/trunk
1014 :     ml-burg | $gf/ml-burg/trunk
1015 :     lexgen | $gf/lexgen/trunk
1016 :     heap2asm | $gf/heap2asm/trunk
1017 :     |
1018 :     cml | $gf/cml/trunk
1019 :     eXene | $gf/eXene/trunk
1020 :     ckit | $gf/ckit/trunk
1021 :     nlffi | $gf/nlffi/trunk
1022 :     |
1023 :     smlnj-c | $gf/smlnj-c/trunk
1024 :    
1025 :     In $gf/admin there are a few useful shell scripts for checking out
1026 :     and maintaining the entire collection of trees:
1027 :    
1028 :     admin/checkout-all.sh [dir]
1029 :     -- optionally creates dir and checks out all trees from their
1030 :     default repositories; if dir is missing, checkout into .
1031 :     admin/refresh-all.sh [dir]
1032 :     -- looks at all trees (from the above list) in dir (default: .)
1033 :     and runs "svn update" if the tree exists and is under
1034 :     subversion control;
1035 :     non-existing or non-subversion trees are skipped
1036 :     admin/stat-all.sh [dir]
1037 :     -- like refresh-all.sh, but runs "svn stat" instead

1184 :    
1185 :     Hooked code for Darwin-specific Intel ABI into main compiler.
1186 :     (This is a temporary solution which relies on the fact that the

1217 :     Description:
1218 :    
1219 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1220 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1221 : blume 2155 at the time when config/preloads is processed, the library has to
1222 : mblume 1878 be referred to by another name. In 110.57 this would be
1223 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1224 :     to be valid as well.)

1279 :     Tag: blume-22051115-versiontool
1280 :     Description:
1281 :    
1282 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1283 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1284 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1285 :     it. Instead, it has the status of "user code", so it should use
1286 :     $/basis.cm to refer to the Basis library. (At least that's true for
1287 :     the purpose of bootstrapping the previous change. In the future it
1288 :     might make sense to have versiontool.cm refer to
1289 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1290 :     compiler itself uses.)
1291 :    
1292 :     Also patched src/system/testml to have it activate those extra anchor
1293 :     bindings in config/extrapathconfig.

1298 :     Tag: blume-22051115-libraries
1299 :     Description:
1300 :    
1301 :     This change affects the way the following libraries are tied into
1302 :     the system:
1303 :    
1304 :     $/basis.cm
1305 :     $/smlnj-lib.cm
1306 :     $/pp-lib.cm
1307 :     $/controls-lib.cm
1308 :     $/html-lib.cm
1309 :     $/ml-yacc-lib.cm
1310 :    
1311 :     These libraries are now internally (as seen from the source code
1312 :     of the implementation itself) known by the following names:
1313 :    
1314 :     $smlnj/basis/basis.cm
1315 :     $smlnj/smlnj-lib/smlnj-lib.cm
1316 :     $smlnj/smlnj-lib/pp-lib.cm
1317 :     $smlnj/smlnj-lib/controls-lib.cm
1318 :     $smlnj/smlnj-lib/html-lib.cm
1319 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1320 :    
1321 :     This makes it possible to work with code that requires different
1322 :     versions of these libraries, and which refers to these libraries using
1323 :     their "default" names (i.e., the first set of names above). In other
1324 :     words, one can un-define or re-define those default names without
1325 :     compromising the proper functioning of the compiler itself.
1326 :    
1327 :     A similar procedure had already been performed for several of the
1328 :     MLRISC libraries that are linked into the compiler. I did some
1329 :     cleanup on this code.
1330 :    
1331 :     A new file in the config directory (named extrapathconfig) is
1332 :     responsible for setting up path anchors that the compiler itself does
1333 :     not need, but that are typically required by user code.

1512 :     Tag: blume-20050516-redump-heap
1513 :     Description:
1514 :    
1515 :     Added mechanism for re-creating a heap file for the interactive system
1516 :     after configuration variables have been changed.
1517 :    
1518 :     CM.redump_heap : string -> unit
1519 :    
1520 :     This is much like SMLofNJ.exportML, but starting from the resulting
1521 : blume 2155 heap does not return to the caller of CM.redump_heap but
1522 : mblume 1792 restarts the interactive system from scratch. The original call of
1523 :     CM.redump_heap does not return but ends the interactive session.
1524 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1525 :    
1526 :     Internally, redump_heap winds the dynamic execution context back to
1527 :     the point where the original heap image was created and re-executes
1528 :     the heap image generation code in the boot code.

1644 :     Tag: blume-20050114-heap2exec
1645 :     Description:
1646 :    
1647 :     Implemented new (but still experimental) heap2exec facility. This is
1648 :     tested under Mac OS X and should work under Linux (will test shortly).
1649 :     It will probably also work on the Sparc (will test some time later).
1650 :    
1651 :     - removed old "HACKED_STANDALONE" hack from runtime
1652 :    
1653 :     To be able to test this, uncomment the request for "heap2asm" in
1654 :     config/targets prior to installation. (Notice that this is different
1655 :     from "heap2exec" mentioned below. Not a typo.)
1656 :    
1657 :     To perform an actual test, run the command
1658 :    
1659 :     $ bin/heap2exec heapfile execfile
1660 :    
1661 :     (You can put heap2exec on your shell's path.)
1662 :    
1663 :     For example, run
1664 :    
1665 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1666 :    
1667 :     This will create a standalone executable called "mly" which you can
1668 :     then invoke directly as a command.

1690 :     Description:
1691 :    
1692 :     * Implemented access to signed and unsigned long long data in NLFFI.
1693 :     (The parameter-passing part of the picture has not complete. But
1694 :     data structure access seems to work.)
1695 :    
1696 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1697 :     (On the Mac, it is big-endian. And that's currently our only
1698 :     PPC platform.)

1715 :    
1716 : blume 2155 The Unix I/O library of SML/NJ on cygwin does not understand
1717 :     Windows style pathname, so problems arise when SMLNJ_HOME is set
1718 :     to a Windows style pathname. _run-sml now converts SMLNJ_HOME

1768 :     is likely still full of bugs and inherently incomplete. (We need to

1813 :     Tag: blume-20041124-position
1814 :     Description:
1815 :    
1816 :     The compiler can now be compiled in a mode that makes structure Position
1817 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1818 :     for the time being.
1819 :    
1820 :     To enable 64-bit positions, use the following procedure:
1821 :    
1822 :     1. Start sml
1823 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1824 :     3. Type
1825 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1826 :     4. Run CMB.make() as usual.
1827 :    
1828 :     This is barely tested. The only test so far was a little SML program
1829 :     counting the number of characters in an 8-gigabyte file by
1830 :     reading it character-by-character. That test was successful.
1831 :    
1832 :     In support of 64-bit positions, a number of new functions have been
1833 :     added to the runtime system.

1877 :     The date string is generated at bootstrap time (during makeml).
1878 :    
1879 :     - In a previous commit, fixed a minor issue with how polyequal is being
1880 :     translated. In particular, the code now "looks through" abstractions.
1881 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1882 :     more efficient code. Important examples for where this matters are
1883 :     the new int64 and word64 types.

1898 :     Description:
1899 :    
1900 :     All the pieces of Word64 are now there, with the exception of the
1901 :     conversions from and to LargeWord. (Eventually these need to be identities,
1902 :     but for the time being they don't even make sense because LargeWord is
1903 :     32-bit wide.)
1904 :    
1905 :     Also started to add similar support for Int64, but major pieces of that
1906 :     are still missing.

1911 :     Tag: blume-20041111-word64
1912 :     Description:
1913 :    
1914 :     Structure Word64 is now (almost) complete, word literals and patterns
1915 :     seem to work. There are a few odd pieces missing. In particular,
1916 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1917 :     at the moment.
1918 :    
1919 :     Making Word64 official would mean that LargeWord becomes Word64. But
1920 :     this requires extreme care because most word-word conversions have to
1921 :     go through LargeWord, so making a mistake means loss of efficiency or
1922 :     worse. Eventually there will be a solution similar to (but actually
1923 :     simpler than) what I did with IntInf.

1954 :    
1955 :     - Changend config/srcarchiveurl from a file just

1957 :     shell script code. The code has access to the $VERSION variable.
1958 :     - Made corresponding changes to config/install.sh and config/unpack.
1959 :     - Default contents of config/srcarchiveurl uses $VERSION and
1960 :     normally does not have to be edited to reflect a version change.
1961 :    
1962 :     (As a result, a version change can be done by just editing
1963 :     config/version, the rest is now automatic.)

1986 :     (the callee already pops the implicit argument which points to

2003 :     Tag: blume-20041020-standalone-backtrace
2004 :     Description:
2005 :    
2006 :     Added a mechanism for getting back-trace information from standalone
2007 :     programs. Here is how it works:
2008 :    
2009 :     1. The part of the program from which you want to get backtrace
2010 :     information (usually the whole program) should be wrapped with
2011 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
2012 :     main program could be modified from something like
2013 :    
2014 :     fun main (pgm, args) = ...
2015 :    
2016 :     to
2017 :    
2018 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2019 :    
2020 :     2. To be able to access BackTrace.monitor, you have to add
2021 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
2022 :     main function.
2023 :    
2024 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2025 :     CM might have created in the past for your project).
2026 :    
2027 :     4. Build the system using this command line:
2028 :    
2029 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2030 :     myprog.cm MyProg.main myprog
2031 :    
2032 :     instead of the usual
2033 :    
2034 :     ml-build myprog.cm MyProg.main myprog
2035 :    
2036 :     I changed a library name:
2037 :    
2038 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2039 :    
2040 :     New libraries:
2041 :    
2042 :     $smlnj-tdp/back-trace.cm
2043 :     -- when loaded causes the back-trace plugin to be installed
2044 :     $smlnj-tdp/coverage.cm
2045 :     -- when loaded causes the coverage plugin to be installed

2061 :     Description:
2062 :    
2063 :     * Test coverage tool added!
2064 :     * Further reorganization of tracing-, debugging-, and profiling support:
2065 :    
2066 :     - moved original BTImp -- now called BackTrace -- into a separate
2067 :     library called $/trace-debug-profile.cm
2068 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2069 :     - only the instrumentation mechanism is now left in the compiler proper
2070 :     - BackTrace module is a plugin which is NOT plugged in by default
2071 :     - Coverage module is another such plugin
2072 :    
2073 :     To get the benefits of any of these plugin modules, the code in
2074 :     question must be compiled with tdp instrumentation turned on. This
2075 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2076 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2077 :    
2078 :     Plugins are selected at link time. (Pre-compiled instrumented code
2079 :     can be re-loaded with different plugins in effect.) When an
2080 :     instrumented module is linked, whatever plugins are at that time
2081 :     enabled will come into effect for that module.

2146 :    
2147 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool
2148 :     is supposed to accept a tool argument called "source", but this did
2149 :     not work because of the clash with the keyword.

2201 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2202 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2203 :     Also, loading the versiontool does not work when rebuilding the system
2204 :     because CM is not properly initialized at that time.

2209 :     Tag: blume-20040929-autoversion
2210 :     Description:
2211 :    
2212 :     Implemented some CM magic to have
2213 :     file src/compiler/TopLevel/main/version.sml
2214 :     generated automagically.
2215 :     The version is taken from two files: config/version and config/release.
2216 :     The first is expected to contain a two-part version number such as 110.49.
2217 :     The second should contain a single number, but it may be missing.
2218 :    
2219 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2220 :     time the version tool is loaded (which is the first time you say CMB.make),
2221 :     then the tool will increment the value stored in config/release every
2222 :     time CMB.make is invoked.
2223 :    
2224 :     The binfile format is now insensitive to anything beyond the first
2225 :     two components of a version number, so bumping the release does not render
2226 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2227 :     during development without invalidating existing binfiles.
2228 :    
2229 :     In any case, every CMB.make updates the date information in version.sml.
2230 :     (This is the date that is printed in the banner.)

2243 :     Tag: blume-20040927-controls
2244 :     Description:
2245 :    
2246 :     Added two pieces of functionality to the Controls interface:
2247 :    
2248 :     1. val save'restore: 'a control -> unit -> unit
2249 :    
2250 :     grabs the current value of the control in stage 1 and restores it
2251 :     in stage 2.
2252 :    
2253 :     2. val set' : 'a control * 'a -> unit -> unit
2254 :    
2255 :     stores the given value into the control in stage 2 (i.e., delayed)
2256 :     but does all error checking in stage 1.
2257 :     (This is for string controls that need to do parse their argument --
2258 :     something that might fail. In some cases, notably in CM, one
2259 :     already knows the intended argument but wants to delay the actual
2260 :     assignment until a time when error recovery would be more difficult.)
2261 :    
2262 :     Changed the handling of controls in tool arguments to classes "sml" and
2263 :     "lazysml":
2264 :     - use Controls.save'restore as a more robust way of restoring the
2265 :     old value (in particular: without having to re-parse the string)
2266 :     - use controls to handle the "overload" keyword in the init group
2267 :     (I believe this change actually fixes a long-standing obscure bug.)

2272 :     Tag: blume-20040927-lazysml
2273 :     Description:
2274 :    
2275 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2276 :     difference to "sml" is that compilation is done with Control.lazysml
2277 :     set to true. A source of class "lazysml" is automatically recognized
2278 :     by a file name suffix of ".lml".
2279 :    
2280 :     In addition to the above feature, the original class "sml" now also
2281 :     supports a tool argument "lazy" which has the same effect. As a
2282 :     result, the following three lines are equivalent:
2283 :    
2284 :     foo.sml : lazysml
2285 :     foo.sml : sml (lazy)
2286 :     foo.sml (lazy)
2287 :    
2288 :     The setting goes into effect both during parsing and during
2289 :     compilation. The original setting is restored right after parsing and
2290 :     after compilation, respectively.
2291 :    
2292 :     In addition to all the above, there is also a general mechanism to set
2293 :     ANY of the "controls" that are available at the command line via
2294 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2295 :     apply as well. (In fact, "lazy" is implemented as a special case of
2296 :     the general mechanism.)
2297 :    
2298 :     The .cm file syntax uses a new keyword tool argument called "with".
2299 :     There are several ways of indicating the desired settings:
2300 :    
2301 :     foo.sml (with:parser.quotations=true)
2302 :     foo.sml (with:(name:parser.quotations value:true))
2303 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2304 :     foo.sml (with:(name1=value1 name2=value2 ...))
2305 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2306 :    
2307 :     etc.
2308 :    
2309 :     Another possible abbreviation is to leave out the =v or value:v part
2310 :     if the name refers to a boolean control (in which case the value is
2311 :     taken to be true). Thus, one could get lazy sml also by saying:
2312 :    
2313 :     foo.sml (with:parser.lazy-keyword=true)
2314 :     foo.sml (with:parser.lazy-keyword)
2315 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2316 :     foo.sml (with:(name:parser.lazy-keyword))

2668 :     Description:
2669 :    
2670 :     Changed the interface of structures Timer and Unix to match the most
2671 :     recent Basis spec.
2672 :    
2673 :     In the case of Unix there still seems to be an open/weird issue:
2674 :    
2675 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2676 :     fresh streams whenever they are called -- as opposed to have them
2677 :     return the same stream every time. This design is supposed to
2678 :     prevent space leaks caused by proc values hanging on to streams.
2679 :    
2680 :     The reap function, on the other hand, is supposed to close the
2681 :     streams. This cannot be done without having a handle on the
2682 :     stream in proc after all...
2683 :    
2684 :     I took the liberty to implement the following stopgap solution:
2685 :    
2686 :     The proc value hangs on to the most recently created stream(s).
2687 :     Reap closes those. If either or both of the two streams hadn't
2688 :     been created at all yet, then reap will close the corresponding
2689 :     file descriptors directly.
2690 :    
2691 :     PS: I don't understand the original space leak argument anymore. If
2692 :     a proc hangs on to the imperative stream, then I/O operations on those
2693 :     will advance the state of the cached stream and avoid the space leak.

2706 :     Tag: blume-20040525-group-owner
2707 :     Description:
2708 :    
2709 :     CM now ignores (but still accepts) the "owner" information in group
2710 :     descriptions. The owner of a group is its next enclosing
2711 :     library. Each group must have a unique owner. (There is a virtual
2712 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2713 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2714 :     and CM would check that such a declaration is correct. The new scheme
2715 :     is to have CM check that for each group there is precisely one owning
2716 :     library.
2717 :    
2718 :     The advantage of the new scheme is that the programmer no longer needs
2719 :     to maintain the somewhat annoying owner information. The downside is
2720 :     that CM cannot enforce the ownership rule across multiple runs of
2721 :     CM.make. Fortunately, enclosing the same group in two different
2722 :     libraries A and B which are not part of the same program does not
2723 :     cause real problems.

2743 :    
2744 :     Arranged for ml-build to clean up after itself a little bit better.
2745 :     The script generates a temporary SML source file and compiles it using
2746 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
2747 :     gets rid of those at the end, so they don't accumulate under .cm.
2748 :    
2749 :     This required a minor change to install.sh because the name of the

2770 :     for the voluminous patch!
2771 :    
2772 :     (I have not tested this patch under win32 yet.)
2773 :    
2774 : mblume 1490 Here is David's e-mail:
2775 :    
2776 :     Hi,
2777 :    
2778 :     Attached to this email you find a diff against sml/nj 110.45
2779 :     that will enable socket support under Windows.
2780 :    
2781 :     To apply the patch (using unix or cygwin)
2782 :     1) gunzip runtime.diff.gz
2783 :     2) "cd" into "src/runtime" in the source tree of a fresh
2784 :     110.45 installation.
2785 :     3) patch -p 1 < [your/path/to]runtime.diff
2786 :    
2787 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2788 :     I only ran a few tests for basic socket client functionality
2789 :     (which worked fine). Especially the functions that use ioctl
2790 : mblume 1490 are not tested at all and might not work (see below).
2791 :    
2792 :     I implemented this since we want to move to a newer version of sml/nj
2793 :     but need socket support in order to use it. This is the first time I
2794 :     even had a look at the sml/nj source, so please review my changes
2795 :     before making this part of the distribution! Here are a few issues
2796 : blume 2155 that I think might be better for someone to solve who is more
2797 : mblume 1490 familiar with the sml/nj source (and socket programming):
2798 :    
2799 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2800 :     exception since I could not figure out what the windows equivalent
2801 :     of these functions is
2802 :    
2803 :     - In sockets-osdep.h there are a some #include statements that are
2804 :     only used in a few files that include sockets-osdep.h
2805 :    
2806 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2807 :     does not process its return value since I don't know how to
2808 :     report an error upwards.
2809 :    
2810 :     - It would probably be good to have a call to WSACleanup() when
2811 : blume 2155 the library is unloaded (if there is such a possibility).
2812 : mblume 1490 Otherwise I think Windows will take care of this automatically
2813 :     when the process finishes.
2814 :    
2815 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2816 :     no idea if that is actually the proper replacement on Windows.
2817 :    
2818 :     - All these issues are marked in the code by "FIXME" comments.
2819 :    
2820 : blume 2155 We use sml/nj extensively in our products and are quite happy
2821 :     with it. I hope this contribution will help you.
2822 : mblume 1490
2823 :     Keep up the good work!

2900 :     Description:
2901 :    
2902 :     Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
2903 :     of SML/NJ. The problem is that
2904 :    
2905 :     lib = dlopen(NULL, ...)
2906 :     f = dlsym(lib, "malloc");
2907 :    
2908 : blume 2155 does not work on Windows unless we explicitly export symbols
2909 :     such as 'malloc' during linking. We fixed this by explicitly
2910 : allenleung 1468 exporting the required symbols with the magic gcc incantation:
2911 :    
2912 :     -Wl,--export-all cygwin.def
2913 :    
2914 :     where cygwin.def is a file containing all the symbols that
2915 : blume 2155 we wish to export.
2916 : allenleung 1468
2917 : blume 2155 I suspect this is a Windows problem and we'll have to
2918 :     do the same (somehow with windows compilers) when
2919 : allenleung 1468 we build the native win32 version with the system
2920 : blume 2155 calls LoadLibrary/GetProcAddress.

2989 :    
2990 :     Eliminated the "dont_move_libraries" directive in config/targets.
2991 :     (The mechanism was broken and could not be fixed easily. Moreover,
2992 :     there does not seem to be any reason not to move all libraries into
2993 :     lib during installation. I originally implemented this directive as a
2994 :     backward-compatibility feature when I first introduced the new CM.
2995 :     Now that things have been stable for a long time and going back to the
2996 :     old CM is not an option, there is no reason to keep it around.)

3045 :     Tag: blume-20030926-ppautoload
3046 :     Description:
3047 :    
3048 :     I modified the read-eval-print loop so that the autoloader gets
3049 :     invoked whenever the prettyprinter tries to look up a symbol that
3050 :     is not currently defined in the toplevel environment but which
3051 :     appears in CM's autoload registry. As a result, we see far fewer of
3052 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3053 :    
3054 :     In addition to this I tried to clean up some pieces of the Basis
3055 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3056 :     instances of these ?.Foo.Bar.xxx names from being printed.
3057 :    
3058 :     The mechanism that picks names for types still needs some work, though.
3059 :     (Right now it seems that if there is a type A.t which is defined to
3060 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3061 :     "?.B.u" although the perhaps more sensible solution would be to use
3062 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3063 :     a chain of DEFtycs not farther than there are corresponding toplevel
3064 :     names in the current environment.)

3070 :     Description:
3071 :    
3072 :     Another installer tweak: All the ML code for the installer is now
3073 :     compiled during CMB.make and put into a little library called
3074 :     $smlnj/installer.cm. The installation then simply invokes
3075 :    
3076 :     sml -m $smlnj/installer.cm
3077 :    
3078 :     and everything happens automagically.
3079 :    
3080 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3081 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3082 :     and BINDIR.
3083 :    
3084 :     The new scheme guarantees that the ML code responsible for the installation
3085 :     is in sync with the APIs of the main system. Also, the installer is
3086 :     somewhat faster because the installer script is precompiled.

3096 :     and CML_SOCKET in terms of SYNCHRONOUS_SOCKET. Removed superfluous
3097 :     implementations of non-blocking operations from CML's Socket
3098 :     structure.

3103 :     Tag: blume-20030924-sockets
3104 :     Description:
3105 :    
3106 :     1. Fixed SOCKET API and implementation to match Basis spec.
3107 :     This required changing the internal representation of sockets to one
3108 :     that remembers (for each socket file descriptor) whether it is currently
3109 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3110 :     call is made only if the state actually needs to change).
3111 :    
3112 :     2. OS-specific details of sockets were moved into separate files, thus
3113 :     making it possible to unify the bulk of the socket implementations
3114 :     between Unix and Win32.
3115 :    
3116 :     3. CML's socket API changed accordingly.
3117 :     (Note that we need to remove non-blocking functions from this API
3118 :     since they are redundant in the case of CML!)
3119 :    
3120 :     4. CML's socket implementation now makes use of non-blocking functions
3121 :     provided by Basis, thus removing all OS-dependent code from this part
3122 :     of CML.
3123 :    
3124 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3237 :     Description:
3238 :    
3239 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3240 :     Modified config/install.bat to take advantage of it. Also modified
3241 :     config/install.sh (and called it config/new-install.sh) to take advantage
3242 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3243 :     independent.)
3244 :    
3245 :     The installer can now install everything under Win32
3246 :     as well as under *nix as long as it compiles.
3247 :    
3248 :     Other changes:
3249 :    
3250 :     - made CML compile again under Win32
3251 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3252 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3253 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3254 :     same as type int; under Win32 it isn't
3255 :     - fixed some slice-related problems in the win32-specific parts of CML
3256 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3257 :     (under Win32, the volume name is case-insensitive, and the
3258 :     OS.Path code compares volume names for equality)

3269 :     cases when presented with the name of a non-existing .cm file.)

3274 : mblume 1352 Tag: blume-20030905-slices-etc
3275 : mblume 1350 Description:
3276 :    
3277 :     1. Changed interface to vectors and arrays in Basis to match
3278 :     (draft) Basis spec.
3279 :     2. Added signatures and implementations of slices according to
3280 :     Basis spec.
3281 :     3. Edited source code throughout the system to make it compile again
3282 :     under 1. and 2. (In some cases code had to be added to have it
3283 :     match the new signatures.)
3284 :     4. MLRISC should be backward-compatible: the copies of the originals
3285 :     of files that needed to change under 3. were retained, the .cm files
3286 :     check the compiler version number and use old versions when
3287 :     appropriate.
3288 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3289 :     dirstream -> string option (in accordance with Basis spec).
3290 :     6. When generating code that counts lines, ml-lex used function
3291 :     CharVector.foldli, taking advantage of its old interface.
3292 :     This has been replaced with the corresponding code from
3293 :     CharVectorSlice. (html-lex must be re-lexed!)
3294 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3295 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3296 :     8. Removed temporary additions (fromInternal, toInternal) from the
3297 :     (now obsolete) IntInf in smlnj-lib/Util.
3298 :     9. Cleaned up structure Byte.
3299 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3300 :     Cleaned/corrected implementation of Date.
3301 :     (Still need to check for correctness; implement better canonicalizeDate.)
3302 :     11. Added "scan" to signature IEEE_REAL.
3303 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3304 :     mod and rem when second operand is 2 (for parity checks).]
3305 :     13. Changed representation of type Time.time, using a single IntInf.int
3306 :     value counting microseconds. This considerably simplified the
3307 :     implementation of structure Time. We now support negative time
3308 :     values; scan and fromString handle signs.
3309 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3310 :     ArraySlice).

3315 :     Tag: blume-20030828-intinf
3316 :     Description:
3317 :    
3318 :     This is a major update which comes with a version number bump
3319 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3320 :     and an implementation of IntInf in the Basis.
3321 :    
3322 :     There are a fairly large number of related changes and updates throughout
3323 :     the system:
3324 :    
3325 :     Basis:
3326 :     - Implemented IntInf.
3327 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3328 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3329 : mblume 1347 - Added FixedInt as a synonym for Int32.
3330 :    
3331 :     compiler:
3332 :     * Added support for a built-in intinf type.
3333 :     - literals
3334 :     - pattern matching
3335 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3336 :     - overloading on literals and operations
3337 :    
3338 :     This required adding a primitive type intinf, some additional
3339 :     primops, and implementations for several non-trivial intinf
3340 :     operations in Core. (The intinf type is completely abstract
3341 :     to the compiler; all operations get delegated back to the Core.)
3342 :    
3343 :     * Intinf equality is handled by polyequal. However, the compiler
3344 :     does not print its usual warning in this case (since polyequal
3345 :     is the right thing to do there).
3346 :    
3347 :     * Improved the organization of structure InlineT.
3348 :    
3349 :     * A word about conversion primops:
3350 :     If conversions involving intinf do not cancel out during
3351 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3352 : mblume 1347 Since all core access must be resolved already during the FLINT
3353 :     translate phase, it would be too late a the time of CPS contract
3354 : mblume 1348 to add new Core calls. For this reason, conversion primops
3355 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3356 :     they are supposed to convert, and 2. the Core function that
3357 :     can help with this conversion if necessary. If CPS contract
3358 : mblume 1348 eliminates a primop, then the associated Core function becomes
3359 :     dead and goes away. Intinf conversion primops that do not get
3360 :     eliminated by CPS contract get rewritten into calls of their
3361 :     core functions by a separate, new phase.
3362 : mblume 1347
3363 :     interactive system:
3364 :     - Control.Print.intinfDepth controls max length of intinf constants
3365 :     being printed. (Analogous to Control.Print.stringDepth.)
3366 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3367 :     duplicates; replaced some of the code with code that makes better
3368 :     use of library functionality.
3369 :    
3370 :     CM:
3371 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3372 :     are no longer silent.
3373 :    
3374 :     CKIT:
3375 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3376 :     in favor of LargeInt -- which is now the same as IntInf.
3377 :     CKIT-knowledgable people should check whether this is what's
3378 :     intended and otherwise change things back to using Int32 or
3379 :     FixedInt.
3380 :    
3381 :     Throughout the code:
3382 : mblume 1348 Started using IntInf.int literals and built-in operations
3383 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3393 :     These changes involve replacement of the emulated old prettyprinter
3394 :     interface with direct use of the SML/NJ Lib PP library, and fixing
3395 :     of a couple of bugs (895, 1186) relating to error messages. A new

3401 : mblume 1342 Date: 2003/08/11 15:45:00 CDT
3402 :     Tag: blume-20030811-windows
3403 :     Description:
3404 :    
3405 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3406 :    
3407 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3408 :    
3409 :     This patch restores SML/NJ's ability to run under win32. There are a
3410 :     number of changes, including fixes for several bugs that had gone
3411 :     unnoticed until now:
3412 :    
3413 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3414 :     trying to run the win32 version from within cygwin.)
3415 :    
3416 :     - There are a number of simple .bat scripts that substitute for their
3417 :     corresponding Unix shell-scripts. (See below.)
3418 :    
3419 :     - The internals of ml-build have been modified slightly. The main
3420 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3421 :     using OS.Process.system, the ML process delegates this task back
3422 :     to the script. Otherwise problems arise in mixed environments such
3423 :     as Cygwin where scripts look and work like Unix scripts, but
3424 :     where OS.Process.system cannot run them.
3425 :    
3426 :     - In CM, the srcpath pickler used native pathname syntax -- which
3427 :     is incorrect in the case of cross-compilation. The new pickle format
3428 :     is independent of platform-specific naming conventions.
3429 :    
3430 :     - Path configuration files (such as lib/pathconfig) can now choose
3431 :     between native and standard syntax. Placing a line of the form
3432 :    
3433 :     standard!
3434 :    
3435 :     into the file causes all subsequent paths to be interpreted using
3436 :     CM standard pathname syntax (= Unix conventions); a line
3437 :    
3438 :     native!
3439 :    
3440 :     switches back to native style. This was needed so that
3441 :     path config files can be written portably, see src/system/pathconfig.
3442 :    
3443 :     - Runtime system:
3444 :    
3445 :     - win32-filesys.c: get_file_time and set_file_time now
3446 :     access modification time, not creation time.
3447 :    
3448 :     - I/O code made aware of new array representation.
3449 :    
3450 :     - Bug fixes in X86.prim.masm.
3451 :    
3452 :     - src/system/makeml made aware of win32. (For use under cygwin
3453 :     and other Unix-environments for windows.)
3454 :    
3455 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3456 :     which caused BinIO.inputAll to fail consistently.
3457 :    
3458 :     .bat scripts:
3459 :    
3460 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3461 :    
3462 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3463 :     applications (sml, ml-yacc, ml-lex).
3464 :     - ml-build.bat: analogous to ml-build.
3465 :     - config\install.bat: Analogous to config/install.sh. This requires
3466 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3467 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3468 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3469 :     and the bootfile hierarchy must have been unpacked under
3470 :     sml.boot.x86-win32.
3471 :     The script is very primitive and does a poor job at error checking.
3472 :     It only installs the base system, ml-lex, and ml-yacc. No other
3473 :     libraries are being installed (i.e., you get only those that
3474 :     are part of the compiler.)
3475 :     - link-sml.bat: analogous to .link-sml, but not currently used
3476 :    
3477 :     Unrelated bug fixes:
3478 :    
3479 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3480 :     types.
3481 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3482 :     otherwise.)

3506 :     Description:
3507 :    
3508 :     Two changes:
3509 :    
3510 :     1. Added a flag for controlling whether non-exhaustive bindings will
3511 :     be treated as errors (default is false).
3512 :     2. Cleaned up the *entire* source tree so that CMB.make goes through
3513 :     without a single non-exhaustive match- or bind warning.

3519 :     Description:
3520 :    
3521 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3522 :    
3523 :     This mainly affects the quality of error messages. However, some
3524 :     of the code is now more straightforward than before. (Treatment of
3525 :     the above four constructs in translate.sml is much simpler than
3526 :     the "macro-expansion" that was going on before. Plus, the mach-
3527 :     compiler no longer gets invoked just to be able to compile an
3528 :     if-expression.)
3529 :    
3530 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3531 :     interactive loop.

3543 : allenleung 1327 the Cygwin library.
3544 :     o Ctrl-C handling may be flaky.
3545 :     o Windows system calls and Windows I/O are not supported.
3546 :    
3547 :     A new set of binfiles is located at:
3548 :    
3549 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3550 :    
3551 :     This is only needed for bootstrapping the cygwin version of smlnj.

3685 :     Description:
3686 :    
3687 :     Fixed a bug in translation of INLMAX (and INLMIN) for the floating-point
3688 :     case. (The sense of the isNaN test was reversed -- which made min and
3689 :     max always return their first argument.)

3703 :     Description:
3704 :    
3705 :     I back-ported my implementation of IEEEReal.fromString from the
3706 :     idlbasis-devel branch so that we can test it.
3707 :    
3708 :     Another small change is that ppDec tries to give more information
3709 :     than just "<sig>" in the case of functors. However, this code is
3710 :     broken in some mysterious way if the functor's body's signature
3711 :     has not been declared by ascription but gets inferred from the
3712 :     implementation. This needs fixing...

3778 :     - Used Controls facility to define MLRISC controls (as opposed to
3779 :     registering MLRISC control ref cells with Controls after the fact)
3780 :     - Fixed messed-up controls priorities.
3781 :    
3782 :     * Removed again all the stuff from config/preloads that one wouldn't
3783 :     be able to preload at the time the initial heap image is built.
3784 :     (Many libraries, e.g., CML, do not exist yet at this time. The
3785 :     only libraries that can be preloaded via config/preloads are those
3786 :     that come bundled with the bootfiles.)

3811 :     Description:
3812 :    
3813 :     0. John Reppy made several modifications to the SML/NJ library.
3814 :     In particular, there is a shiny new controls-lib.cm.
3815 :    
3816 :     1. Pushed new controls interface through compiler so that everything
3817 :     compiles again.
3818 :    
3819 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3820 :     SML/NJ library (so that CML compiles again).
3821 :    
3822 :     3. Modified init scripts because XXX_DEFAULT environment variables
3823 :     are no longer with us. (Boot-time initialization is now done
3824 :     using the same environment variables that are also used for
3825 :     startup-time initialization of controls.)

3831 :     Description:
3832 :    
3833 :     All pseudo-ops emitted before the first segment declaration
3834 :     such as TEXT, DATA, and BSS directives are assumed to be global
3835 :     declarations and are emitted first in the assembly file. This is
3836 :     useful in a number of situations where one has pseudo-ops that are not
3837 :     specific to any segment, and also works around the constraint that one
3838 :     cannot have client pseudo-ops in the TEXT segment.
3839 :    
3840 :     Because no segment is associated with these declarations it is
3841 :     an error to allocate any space or objects before the first segment
3842 :     directive and an exception will be raised. However, we cannot make
3843 :     this check for client pseudo-ops.
3844 :    
3845 :     These top level declarations are a field in the CFG graph_info.
3846 :     In theory you can continue to add to this field after the CFG has been
3847 :     built -- provided you know what you are doing;-)

3853 :     Description:
3854 :    
3855 :     A few minor bugfixes:
3856 :    
3857 :     - Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
3858 :     (Bogus printouts for redefined bindings still occur. Compiler
3859 :     bug should no longer occur now. We need to redo the prettyprinter
3860 :     from scratch.)
3861 :    
3862 :     - CM pathname printer now also adds escape sequences for ( and )
3863 :    
3864 :     - commend and docu fixes for ml-nlffi

3869 :     Tag: blume-20020510-erg-textio
3870 :     Description:
3871 :    
3872 :     Applied the following bugfix provided by Emden Gansner:
3873 :    
3874 :     Output is corrupted when outputSubstr is used rather than output.
3875 :    
3876 : blume 2155 The problem occurs when a substring
3877 : blume 1189
3878 :     ss = (s, dataStart, dataLen)
3879 :    
3880 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3881 :     avail bytes of s, starting at index dataStart, are copied into the
3882 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3883 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3884 :     starting this copy at index dataStart+avail in s, the current code
3885 : blume 1189 starts the copy at index avail.
3886 :    
3887 :     Fix:
3888 :     In text-io-fn.sml, change line 695 from
3889 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3890 : blume 2155 to
3891 : blume 1189 val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

3907 :     Description:
3908 :    
3909 :     Added full support for div/mod/rem/quot on the x86, using the machine
3910 :     instruction's two results (without clumsily recomputing the remainder)
3911 :     directly where appropriate.
3912 :    
3913 :     Some more extensive power-of-two support was added to the x86 instruction
3914 :     selector (avoiding expensive divs, mods, and muls where they can be
3915 :     replaced with cheaper shifts and masks). However, this sort of thing
3916 :     ought to be done earlier, e.g., within the CPS optimizer so that
3917 :     all architectures benefit from it.
3918 :    
3919 :     The compiler compiles to a fixed point, but changes might be somewhat
3920 :     fragile nevertheless. Please, report any strange things that you might
3921 :     see wrt. div/mod/quot/rem...

3927 :     Description:
3928 :    
3929 :     Fixed my broken div/mod logic. Unfortunately, this means that the
3930 :     inline code for div/mod now has one more comparison than before.
3931 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3932 :     The problem was with quotient = 0, because that alone does not tell
3933 :     us which way the rounding went. One then has to look at whether
3934 :     remainder and divisor have the same sign... :(
3935 :

3942 :     Description:
3943 :    
3944 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
3945 :    
3946 :     Primops have changed. This means that the bin/boot-file formats have
3947 :     changed as well.
3948 :    
3949 :     To make sure that there is no confusion, I made a new version.
3950 :    
3951 :    
3952 :     CHANGES:
3953 :    
3954 :     * removed REMT from mltree (remainder should never overflow).
3955 :    
3956 :     * added primops to deal with divisions of all flavors to the frontend
3957 :    
3958 :     * handled these primops all the way through so they map to their respective
3959 :     MLRISC support
3960 :    
3961 :     * used these primops in the implementation of Int, Int32, Word, Word32
3962 :    
3963 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3964 :    
3965 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
3966 :    
3967 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3968 :     floating point
3969 :    
3970 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3971 :     and Real (but Real.abs maps to a separate floating-point-only primop)
3972 :    
3973 :    
3974 :     TODO items:
3975 :    
3976 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
3977 :     instructions because the machine instruction encoder cannot handle
3978 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
3979 :     REM in the first place, and REM is supported by the x86 machine coder.)
3980 :    
3981 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
3982 :     selection phase. (The two can be streamlined because the hardware
3983 :     delivers both quotient and remainder at the same time anyway.)
3984 :    
3985 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
3986 :     (Currently the behavior is inconsistent both across architectures and
3987 :     wrt. the draft Basis spec.)
3988 :    
3989 :     * Word8 should eventually be handled natively, too.
3990 :    
3991 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
3992 :     as if there currently is no execution path that could trigger it in
3993 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
3994 :     hold for things like multiplication and division.)

3999 :     Tag: blume-20020327-mlrisc-divisions
4000 :     Description:
4001 :    
4002 :     Added support for all four division operations (ML's div, mod, quot,
4003 :     and rem) to MLRISC. In the course of doing so, I also rationalized
4004 :     the naming (no more annoying switch-around of DIV and QUOT), by
4005 :     parameterizing the operation by div_rounding_mode (which can be either
4006 :     DIV_TO_ZERO or DIV_TO_NEGINF).
4007 :    
4008 :     The generic MLTreeGen functor takes care of compiling all four
4009 :     operations down to only round-to-zero div.
4010 :    
4011 :     Missing pieces:
4012 :    
4013 :     * Doing something smarter than relying on MLTreeGen on architectures
4014 :     like, e.g., the x86 where hardware division delivers both quotient and
4015 :     remainder at the same time. With this, the implementation of the
4016 :     round-to-neginf operations could be further streamlined.
4017 :    
4018 :     * Remove inlining support for div/mod/rem from the frontend and replace it
4019 :     with primops that get carried through to the backend. Do this for all
4020 :     int and word types.

4025 :     Tag: blume-20020325-divmod
4026 :     Description:
4027 :    
4028 :     I improved (hopefully without breaking them) the implementation of Int.div,
4029 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
4030 :     advantage of the following observations:
4031 :    
4032 :     Let q = x quot y r = x rem y
4033 :     d = x div y m = x mod y
4034 :    
4035 :     where "quot" is the round-to-zero version of integer division that
4036 :     hardware usually provides. Then we have:
4037 :    
4038 :     r = x - q * y where neither the * nor the - will overflow
4039 :     d = if q >= 0 orelse x = q * y then q else q - 1
4040 :     where neither the * nor the - will overflow
4041 :     m = if q >= 0 orelse r = 0 then r else r + y
4042 :     where the + will not overflow
4043 :    
4044 :     This results in substantial simplification of the generated code.
4045 :     The following table shows the number of CFG nodes and edges generated
4046 :     for
4047 :     fun f (x, y) = x OPER y
4048 :     (* with OPER \in div, mod, quot, rem *)
4049 :    
4050 :    
4051 :     OPER | nodes(old) | edges(old) | nodes(new) | edges(new)
4052 :     --------------------------------------------------------

4161 : george 1168 Description:
4162 :    
4163 : blume 2155 Implemented the Ball-Larus branch prediction-heuristics, and
4164 : george 1168 incorporated graphical viewers for control flow graphs.
4165 :    
4166 : george 1171 Ball-Larus Heuristics:
4167 : george 1168 ---------------------
4168 :     See the file compiler/CodeGen/cpscompile/cpsBranchProb.sml.
4169 :    
4170 :     By design it uses the Dempster-Shafer theory for combining
4171 :     probabilities. For example, in the function:
4172 :    
4173 :     fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)
4174 :    
4175 :     the ball-larus heuristics predicts that the n=0 is unlikely
4176 :     (OH-heuristic), and the 'then' branch is unlikely because of the
4177 :     RH-heuristic -- giving the 'then' branch an even lower combined
4178 : george 1171 probability using the Dempster-Shafer theory.
4179 : george 1168
4180 :     Finally, John Reppy's loop analysis in MLRISC, further lowers the
4181 :     probability of the 'then' branch because of the loop in the else
4182 :     branch.
4183 :    
4184 :    
4185 :     Graphical Viewing:
4186 : blume 2155 ------------------
4187 : george 1168 I merely plugged in Allen's graphical viewers into the compiler. The
4188 :     additional code is not much. At the top level, saying:
4189 :    
4190 :     Control.MLRISC.getFlag "cfg-graphical-view" := true;
4191 :    
4192 :     will display the graphical view of the control flow graph just before
