446 :     Description:
447 :    
448 :     After Aaron Turon's bug fix for ml-ulex (handling the ^ character
449 :     in legacy mode), re-ran the lexer generator on all lex input files
450 :     and committed the results.
451 :    
452 :     This should fix the problem with ckit and nlffi that was reported
453 :     by Vesa A. Norrman.

466 :     Revision: 2650
467 :     Description:
468 :    
469 :     3rd merge of base from primop-branch-3 into the trunk.
470 :     Additional bug fixes included:
471 :    
472 :     * Timer.cpu_timer, etc. type printing corrected (by making
473 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
474 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
475 :     Stefan Monnier)

479 :     Date: 2007/05/31 11:40:00 CDT
480 :     Description:
481 :    
482 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
483 :    
484 :     Also, changed the handling of "no core access": When translate.sml
485 :     needs access to a core exception at a time when the core has not
486 :     been set up yet (this only happens when compiling system/smlnj/init/*),
487 :     then don't bother generating the corresponding tests.
488 :    
489 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
490 :     the exception. Unfortunately, that confuses the plambda type checker.
491 :     Moreover, it does not do any good, because at runtime we don't expect
492 :     such an exception to be ever raised. (The code in system/smlnj/init/*
493 :     has to be written very carefully with this in mind!)

504 :     Date: 2007/05/29 19:00:00 CDT
505 :     Description:
506 :    
507 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
508 :     with an explicit test for zero division. This should fixes several
509 :     regressions and makes it possible for downstream optimization phases
510 :     to treat these operations as "pure" when they are applied to unsigned
511 :     operands.

516 :     Description:
517 :    
518 :     Added the new MLRISC code generator for the AMD64. This version,
519 :     in contrast to the previous one, uses SSE registers and instructions
520 :     for all floating-point computations.

525 : jhr 2613 Description:
526 :    
527 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
528 :     for bugs #1415 and #1416. We also now correctly handle format characters that
529 :     lie outside the specified set.

533 :     Date: 2007/05/23 22:30:00 CDT
534 :     Description:
535 :    
536 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
537 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
538 :    
539 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
540 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
541 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
542 :     while running CMB.make. The point is that the single symbol
543 :     NO_PLUGINS is definde in all three cases.)
544 :    
545 :     I changed the three locations within the sources that get compiled
546 :     during CMB.make where ml-yacc or ml-lex input is processed: When
547 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
548 :     is bypassed.
549 :    
550 :     When bootstrapping new versions of the compiler, there can be
551 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
552 :     are not available or otherwise not operational. In this case one can
553 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
554 :     do so, the following command should be issued at the interactive
555 :     prompt:
556 :    
557 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
558 :    
559 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
560 :     files that normally would be generated by ml-yacc and ml-lex.
561 :     (Copies of these files are in the repository.)

567 :     Description:
568 :    
569 :     2nd merge of base from primop-branch-3 into the trunk.

571 :     Date.scan and Date.fromString fixed;
572 :     Overloading resolution fixed and some type printing problems corrected.

576 : blume 2589 Date: 2007/05/23 09:50:00 CDT
577 :     Description:
578 :    
579 :     Changed the installation mechanism for CM tool plugins. These are
580 :     just libaries and now get installed like ordinary libaries.
581 :    
582 :     There are now a number of new installation targets that give some
583 :     fine-grain control over what classes and suffixes are known, and what
584 :     they will map to.
585 :     See config/targets for details.
586 :    
587 :     The code that caused plugin installation as part of running a
588 :     tool's "build" script has been removed. (The build script is for
589 :     building, not for installing.)

593 : blume 2578 Date: 2007/05/22 11:50:00 CDT
594 :     Description:
595 :    
596 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
597 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
598 :     CM fail if a shell tool reports a non-success exit status. If
599 :     the control is set to true, then CM will press on after tool failures
600 :     in the event that the target files exist (even though they are
601 :     considered outdated). Turning the control to true can be useful for
602 :     bootstrapping.

606 :     Date: 2007/05/19
607 :     Description:
608 :    
609 :     Merge of ml-lpt revisions for 110.64.
610 :    
611 :     The name of several ml-lpt-lib modules has changed:
612 :     Repair => AntlrRepair
613 :     StreamPos => AntlrStreamPos
614 :     ErrHandlerFn => AntlrErrHandler
615 :     EBNF => AntlrEBNF
616 :    
617 :     The ml-antlr specification format has changed: declarations such as
618 :     %tokens and nonterminal definitions can occur *multiple* times in the
619 :     same specification. The semantics are such that each new declaration
620 :     extends the previous ones. This does not apply to %start or %name,
621 :     of course.
622 :    
623 :     Importing a grammar via %import now includes *all* declarations in from
624 :     the imported grammar, except for %name, %entry, and %start. Tokens
625 :     and nonterminals can be dropped using the new %dropping clause of the
626 :     %import directive; the separate %drop and %extend have been removed.
627 :    
628 :     We now allow optional type annotations on nonterminals, using the %nonterms
629 :     directive as in ml-yacc.
630 :    
631 :     The refcell construct is now implemented using SML's regular reference
632 :     cells, so the :== and !! notation has been deprecated.
633 :    
634 :     The ml-antlr tool now does much more checking of specifications, and
635 :     its error messages have been greatly improved. Error repair for
636 :     generated parsers has been completely rewritten, and is now both
637 :     much faster and more accurate.
638 :    
639 :     ml-ulex is now more lenient with escape codes (non-SML-standard
640 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
641 :     Also, character classes may now include a "-" character at the beginning
642 :     as is standard in most other regexp tools.
643 :    
644 :     All of these changes are documented in the user guide, which has
645 :     been updated and improved with this merge.

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

797 :    
798 :     Added preliminary support in MLRISC for Staged Allocation, a technique
799 :     for specifying calling conventions (see
800 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
801 :     Initially, we plan to use this code to generate C calls for the AMD64.
802 :    
803 :     The staged allocation code base resides in MLRISC/staged-allocation,
804 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

874 :     the interface for creating streams in ml-ulex (we now support
875 :     stream creation from several kinds of sources). Overall, the
876 :     tools are now quite stable, and their interfaces are unlikely to
877 :     change in a way that would break compatibility. More work,
878 :     however, is needed in the documentation.

883 :     Description:
884 :    
885 :     Implemented library installer. Moved CM plugin code for
886 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
887 :     their respective trees. Implemented CM plugin for ml-ulex
888 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
889 :     and ml-antlr.
890 :    
891 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
892 :     CM tools. (It turns out to be too messy to do otherwise because
893 :     there is too much code that during installation relies on the presence
894 :     of these tools -- resulting in a tricky ordering problem.)

899 :     Description:
900 :    
901 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
902 :     Modified CM's startup code to use shiftArgs as it processes
903 :     command line arguments. This way, the init code in each .sml-file
904 :     or library that is mentioned at the top level will see only
905 :     those arguments that have not yet been processed at this point.
906 :     In other words, the init code can "seize control" and process the
907 :     remaining command line.

974 :     Description:
975 :    
976 :     Added code to CM's "standard shell tool" implementation which
977 :     causes it to tolerate (with a warning) the situation where the shell
978 :     command fails (e.g., due to the shell command's non-existence)
979 :     as long as all target files exist.
980 :    
981 :     This makes it possible to, e.g., build ml-yacc from sources even if
982 :     svn checkout messed up the time stamps on files in such a way that
983 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
984 :     be needed to re-process yacc.grm, but obviously it might not yet be
985 :     available at that time.)

991 :    
992 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
993 :     recvVecFromNB' in the SOCKET signature. This error is actually
994 :     in the SML Basis specification too.

1024 :     Tag: release-110.60
1025 :     Description:
1026 :    
1027 :     New working release (110.60). NEW BOOTFILES!
1028 :    
1029 :     This is the first subversion-hosted release. There are also changes
1030 :     to the directory layout. Here is a table:
1031 :    
1032 :     (All pathnames are relative to the SML/NJ "root" directory.)
1033 :    
1034 :     config -> config
1035 :    
1036 :     src/cm -> base/cm
1037 :     src/compiler -> base/compiler
1038 :     src/runtime -> base/runtime
1039 :     src/system -> base/system
1040 :    
1041 :     src/cm/pgraph -> pgraph
1042 :    
1043 :     src/READMES -> base/READMES
1044 :     src/$notefile -> base/NOTES/$notefile
1045 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1046 :     MACOSXINSTALL WININSTALL
1047 :    
1048 :     src/smlnj-lib -> smlnj-lib
1049 :     src/MLRISC -> MLRISC
1050 :     ckit -> ckit
1051 :     src/cml -> cml
1052 :     src/eXene -> eXene
1053 :     src/heap2asm -> heap2asm
1054 :     src/lexgen -> lexgen
1055 :     src/ml-burg -> ml-burg
1056 :     src/ml-lex -> ml-lex
1057 :     src/ml-yacc -> ml-yacc
1058 :     src/ml-nlffi-lib -> nlffi/lib
1059 :     src/ml-nlffigen -> nlffi/gen
1060 :     src/smlnj-c -> smlnj-c
1061 :     src/tools/TraceDebugProf -> trace-debug-profile
1062 :    
1063 :     In addition, there is also a new
1064 :    
1065 :     ml-lpt
1066 :    
1067 :     directory containing two new program generator tools: ml-ulex and
1068 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1069 :     LL(k) parser generator). These tools are currently "beta-quality"
1070 :    
1071 :     The latest versios of the sources can now be obtained anonymously
1072 :     via subversion. For this, it is useful to first check out
1073 :    
1074 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1075 :    
1076 :     and put the resulting directory on your shell's PATH. This provides
1077 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
1078 :     and refresh-all.sh.
1079 :    
1080 :     To create a freshly checked-out copy of the sources, do
1081 :    
1082 :     checkout-all.sh [dir]
1083 :    
1084 :     where dir is the optional SML/NJ root directory (default is ".").
1085 :    
1086 :     This creates the above directory layout. Each subdirectory of
1087 :     the root is under individual subversion control. The stat-all.sh
1088 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
1089 :     each of these subtrees.

1092 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
1093 : blume 2155 Date: 2006/11/02 12:20:00 CST
1094 :     Description:
1095 :    
1096 :     Reorganized directory layout.
1097 :    
1098 :     This is a temporary solution, more reorganization is to come.
1099 :    
1100 :     The basic idea is to have a number of toplevel trees, each corresponding
1101 :     to a well-defined part of the overall system. Each part can be
1102 :     maintained individually, even in separate source repositories,
1103 :     although currently we still serve everything out of the main
1104 :     smlnj-gforge tree.
1105 :    
1106 :     Installer and and scripts have been updated to reflect the new
1107 :     layout. The installer (base/src/system/smlnj/installer) is now
1108 :     "scriptable" to avoid burning too much knowledge about the
1109 :     layout into SML source code. The main script used by the installer
1110 :     is in config/actions.
1111 :    
1112 :     The main change is that many of the subdirectories of what used to
1113 :     be known as "src" have moved to the toplevel. The "src" directory
1114 :     itself has moved down into a subtree called "base". (We may eventually
1115 :     get rid of the extra level of indirection represented by "src".)
1116 :    
1117 :     The layout is now as follows:
1118 :    
1119 :     toplevel tree name | default repository
1120 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1121 :     -------------------+----------------------------------------------------
1122 :     config | $gf/config/trunk
1123 :     |
1124 :     base | $gf/sml/trunk
1125 :     |
1126 :     smlnj-lib | $gf/smlnj-lib/trunk
1127 :     MLRISC | $gf/MLRISC/trunk
1128 :     |
1129 :     ml-yacc | $gf/ml-yacc/trunk
1130 :     ml-lex | $gf/ml-lex/trunk
1131 :     ml-burg | $gf/ml-burg/trunk
1132 :     lexgen | $gf/lexgen/trunk
1133 :     heap2asm | $gf/heap2asm/trunk
1134 :     |
1135 :     cml | $gf/cml/trunk
1136 :     eXene | $gf/eXene/trunk
1137 :     ckit | $gf/ckit/trunk
1138 :     nlffi | $gf/nlffi/trunk
1139 :     |
1140 :     smlnj-c | $gf/smlnj-c/trunk
1141 :    
1142 :     In $gf/admin there are a few useful shell scripts for checking out
1143 :     and maintaining the entire collection of trees:
1144 :    
1145 :     admin/checkout-all.sh [dir]
1146 :     -- optionally creates dir and checks out all trees from their
1147 :     default repositories; if dir is missing, checkout into .
1148 :     admin/refresh-all.sh [dir]
1149 :     -- looks at all trees (from the above list) in dir (default: .)
1150 :     and runs "svn update" if the tree exists and is under
1151 :     subversion control;
1152 :     non-existing or non-subversion trees are skipped
1153 :     admin/stat-all.sh [dir]
1154 :     -- like refresh-all.sh, but runs "svn stat" instead

1300 :     Description:
1301 :    
1302 :     Hooked code for Darwin-specific Intel ABI into main compiler.
1303 :     (This is a temporary solution which relies on the fact that the
1304 :     compiler itself does not use NLFFI. Eventually we need to divorce
1305 :     intel mac from generic x86 unix code and make separate sets of binaries.)

1334 :     Description:
1335 :    
1336 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1337 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1338 : blume 2155 at the time when config/preloads is processed, the library has to
1339 : mblume 1878 be referred to by another name. In 110.57 this would be
1340 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1341 :     to be valid as well.)
1342 :

1396 :     Tag: blume-22051115-versiontool
1397 :     Description:
1398 :    
1399 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1400 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1401 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1402 :     it. Instead, it has the status of "user code", so it should use
1403 :     $/basis.cm to refer to the Basis library. (At least that's true for
1404 :     the purpose of bootstrapping the previous change. In the future it
1405 :     might make sense to have versiontool.cm refer to
1406 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1407 :     compiler itself uses.)
1408 :    
1409 :     Also patched src/system/testml to have it activate those extra anchor
1410 :     bindings in config/extrapathconfig.

1415 :     Tag: blume-22051115-libraries
1416 :     Description:
1417 :    
1418 :     This change affects the way the following libraries are tied into
1419 :     the system:
1420 :    
1421 :     $/basis.cm
1422 :     $/smlnj-lib.cm
1423 :     $/pp-lib.cm
1424 :     $/controls-lib.cm
1425 :     $/html-lib.cm
1426 :     $/ml-yacc-lib.cm
1427 :    
1428 :     These libraries are now internally (as seen from the source code
1429 :     of the implementation itself) known by the following names:
1430 :    
1431 :     $smlnj/basis/basis.cm
1432 :     $smlnj/smlnj-lib/smlnj-lib.cm
1433 :     $smlnj/smlnj-lib/pp-lib.cm
1434 :     $smlnj/smlnj-lib/controls-lib.cm
1435 :     $smlnj/smlnj-lib/html-lib.cm
1436 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1437 :    
1438 :     This makes it possible to work with code that requires different
1439 :     versions of these libraries, and which refers to these libraries using
1440 :     their "default" names (i.e., the first set of names above). In other
1441 :     words, one can un-define or re-define those default names without
1442 :     compromising the proper functioning of the compiler itself.
1443 :    
1444 :     A similar procedure had already been performed for several of the
1445 :     MLRISC libraries that are linked into the compiler. I did some
1446 :     cleanup on this code.
1447 :    
1448 :     A new file in the config directory (named extrapathconfig) is
1449 :     responsible for setting up path anchors that the compiler itself does
1450 :     not need, but that are typically required by user code.

1630 :     Description:
1631 :    
1632 :     Added mechanism for re-creating a heap file for the interactive system
1633 :     after configuration variables have been changed.
1634 :    
1635 :     CM.redump_heap : string -> unit
1636 :    
1637 :     This is much like SMLofNJ.exportML, but starting from the resulting
1638 : blume 2155 heap does not return to the caller of CM.redump_heap but
1639 : mblume 1792 restarts the interactive system from scratch. The original call of
1640 :     CM.redump_heap does not return but ends the interactive session.
1641 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1642 :    
1643 :     Internally, redump_heap winds the dynamic execution context back to
1644 :     the point where the original heap image was created and re-executes
1645 :     the heap image generation code in the boot code.

1690 :     structure Atom in CML. (I had accidentally used a mailbox instead of
1691 :     an mvar, leaving the door open for races.)

1705 :     Description:
1706 :    
1707 :     Brought back SMLofNJ.Susp. The underlying suspension type is the one
1708 :     implemented in Core -- which means that it is the same as the one used
1709 :     by the lazy extension.

1761 :     Tag: blume-20050114-heap2exec
1762 :     Description:
1763 :    
1764 :     Implemented new (but still experimental) heap2exec facility. This is
1765 :     tested under Mac OS X and should work under Linux (will test shortly).
1766 :     It will probably also work on the Sparc (will test some time later).
1767 :    
1768 :     - removed old "HACKED_STANDALONE" hack from runtime
1769 :    
1770 :     To be able to test this, uncomment the request for "heap2asm" in
1771 :     config/targets prior to installation. (Notice that this is different
1772 :     from "heap2exec" mentioned below. Not a typo.)
1773 :    
1774 :     To perform an actual test, run the command
1775 :    
1776 :     $ bin/heap2exec heapfile execfile
1777 :    
1778 :     (You can put heap2exec on your shell's path.)
1779 :    
1780 :     For example, run
1781 :    
1782 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1783 :    
1784 :     This will create a standalone executable called "mly" which you can
1785 :     then invoke directly as a command.

1811 :     data structure access seems to work.)
1812 :    
1813 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1814 :     (On the Mac, it is big-endian. And that's currently our only
1815 :     PPC platform.)

1930 :     Tag: blume-20041124-position
1931 :     Description:
1932 :    
1933 :     The compiler can now be compiled in a mode that makes structure Position
1934 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1935 :     for the time being.
1936 :    
1937 :     To enable 64-bit positions, use the following procedure:
1938 :    
1939 :     1. Start sml
1940 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1941 :     3. Type
1942 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1943 :     4. Run CMB.make() as usual.
1944 :    
1945 :     This is barely tested. The only test so far was a little SML program
1946 :     counting the number of characters in an 8-gigabyte file by
1947 :     reading it character-by-character. That test was successful.
1948 :    
1949 :     In support of 64-bit positions, a number of new functions have been
1950 :     added to the runtime system.

1995 :    
1996 :     - In a previous commit, fixed a minor issue with how polyequal is being
1997 :     translated. In particular, the code now "looks through" abstractions.
1998 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1999 :     more efficient code. Important examples for where this matters are
2000 :     the new int64 and word64 types.

2017 :     All the pieces of Word64 are now there, with the exception of the
2018 :     conversions from and to LargeWord. (Eventually these need to be identities,
2019 :     but for the time being they don't even make sense because LargeWord is
2020 :     32-bit wide.)

2022 :     Also started to add similar support for Int64, but major pieces of that
2023 :     are still missing.

2029 :     Description:
2030 :    
2031 :     Structure Word64 is now (almost) complete, word literals and patterns
2032 :     seem to work. There are a few odd pieces missing. In particular,
2033 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2034 :     at the moment.
2035 :    
2036 :     Making Word64 official would mean that LargeWord becomes Word64. But
2037 :     this requires extreme care because most word-word conversions have to
2038 :     go through LargeWord, so making a mistake means loss of efficiency or
2039 :     worse. Eventually there will be a solution similar to (but actually
2040 :     simpler than) what I did with IntInf.

2077 :     normally does not have to be edited to reflect a version change.
2078 :    
2079 :     (As a result, a version change can be done by just editing
2080 :     config/version, the rest is now automatic.)

2096 :    
2097 :     This is the HISTORY entry for two earlier commits, both concerning
2098 :     the x86 c-calls code in MLRISC:
2099 :    
2100 :     - added a missing LOAD in the code that deals with struct arguments
2101 :     - made sure the caller does not add the wrong number of bytes to the
2102 :     stack pointer after a call of a function returning a struct
2103 :     (the callee already pops the implicit argument which points to
2104 :     the space reserved for the result)

2120 :     Tag: blume-20041020-standalone-backtrace
2121 :     Description:
2122 :    
2123 :     Added a mechanism for getting back-trace information from standalone
2124 :     programs. Here is how it works:
2125 :    
2126 :     1. The part of the program from which you want to get backtrace
2127 :     information (usually the whole program) should be wrapped with
2128 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
2129 :     main program could be modified from something like
2130 :    
2131 :     fun main (pgm, args) = ...
2132 :    
2133 :     to
2134 :    
2135 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2136 :    
2137 :     2. To be able to access BackTrace.monitor, you have to add
2138 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
2139 :     main function.
2140 :    
2141 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2142 :     CM might have created in the past for your project).
2143 :    
2144 :     4. Build the system using this command line:
2145 :    
2146 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2147 :     myprog.cm MyProg.main myprog
2148 :    
2149 :     instead of the usual
2150 :    
2151 :     ml-build myprog.cm MyProg.main myprog
2152 :    
2153 :     I changed a library name:
2154 :    
2155 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2156 :    
2157 :     New libraries:
2158 :    
2159 :     $smlnj-tdp/back-trace.cm
2160 :     -- when loaded causes the back-trace plugin to be installed
2161 :     $smlnj-tdp/coverage.cm
2162 :     -- when loaded causes the coverage plugin to be installed

2178 :     Description:
2179 :    
2180 :     * Test coverage tool added!
2181 :     * Further reorganization of tracing-, debugging-, and profiling support:
2182 :    
2183 :     - moved original BTImp -- now called BackTrace -- into a separate
2184 :     library called $/trace-debug-profile.cm
2185 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2186 :     - only the instrumentation mechanism is now left in the compiler proper
2187 :     - BackTrace module is a plugin which is NOT plugged in by default
2188 :     - Coverage module is another such plugin
2189 :    
2190 :     To get the benefits of any of these plugin modules, the code in
2191 :     question must be compiled with tdp instrumentation turned on. This
2192 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2193 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2194 :    
2195 :     Plugins are selected at link time. (Pre-compiled instrumented code
2196 :     can be re-loaded with different plugins in effect.) When an
2197 :     instrumented module is linked, whatever plugins are at that time
2198 :     enabled will come into effect for that module.
2199 :    
2200 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2201 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2202 :     To enable the coverage plugin, load the same library and invoke
2203 :     Coverage.install().
2204 :    
2205 :     Back-traces are generated automatically on uncaught exceptions and
2206 :     when the code in question explicitly invokes BackTrace.trigger().
2207 :    
2208 :     Coverage (and execution frequency-) information must be queried
2209 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2225 :    
2226 :     Some rationalization of names:

2229 :     etc.
2230 :    
2231 :     This is is preparation of using the original back-trace
2232 :     instrumentation for other purposes. "TDP" stands for
2233 :     Trace/Debug/Profile.
2234 :    
2235 :     The control flag controlling whether instrumentation is on or off is now
2236 :     registered under a different name, so instead of running sml as
2237 :    
2238 :     sml -Cinstrument.btrace-mode=true
2239 :

2258 :     Description:
2259 :    
2260 :     Fixed handling of keywords in .cm files: After seeing "is" the lexer
2261 :     treats subsequent occurrences of "group", "library", "source", "is",
2262 :     "*", and "-" as ordinary identifiers rather than keywords.
2263 :    
2264 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool
2265 :     is supposed to accept a tool argument called "source", but this did
2266 :     not work because of the clash with the keyword.

2310 :    
2311 :     * Moved the "version" magic into its own little library under

2314 : mblume 1639
2315 : mblume 1672 * At the same time, structure CompilerVersion is now known as

2317 : mblume 1639
2318 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2319 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2320 :     Also, loading the versiontool does not work when rebuilding the system
2321 :     because CM is not properly initialized at that time.

2326 :     Tag: blume-20040929-autoversion
2327 :     Description:
2328 :    
2329 :     Implemented some CM magic to have
2330 :     file src/compiler/TopLevel/main/version.sml
2331 :     generated automagically.
2332 :     The version is taken from two files: config/version and config/release.
2333 :     The first is expected to contain a two-part version number such as 110.49.
2334 :     The second should contain a single number, but it may be missing.
2335 :    
2336 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2337 :     time the version tool is loaded (which is the first time you say CMB.make),
2338 :     then the tool will increment the value stored in config/release every
2339 :     time CMB.make is invoked.
2340 :    
2341 :     The binfile format is now insensitive to anything beyond the first
2342 :     two components of a version number, so bumping the release does not render
2343 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2344 :     during development without invalidating existing binfiles.
2345 :    
2346 :     In any case, every CMB.make updates the date information in version.sml.
2347 :     (This is the date that is printed in the banner.)

2360 :     Tag: blume-20040927-controls
2361 :     Description:
2362 :    
2363 :     Added two pieces of functionality to the Controls interface:
2364 :    
2365 :     1. val save'restore: 'a control -> unit -> unit
2366 :    
2367 :     grabs the current value of the control in stage 1 and restores it
2368 :     in stage 2.
2369 :    
2370 :     2. val set' : 'a control * 'a -> unit -> unit
2371 :    
2372 :     stores the given value into the control in stage 2 (i.e., delayed)
2373 :     but does all error checking in stage 1.
2374 :     (This is for string controls that need to do parse their argument --
2375 :     something that might fail. In some cases, notably in CM, one
2376 :     already knows the intended argument but wants to delay the actual
2377 :     assignment until a time when error recovery would be more difficult.)
2378 :    
2379 :     Changed the handling of controls in tool arguments to classes "sml" and
2380 :     "lazysml":
2381 :     - use Controls.save'restore as a more robust way of restoring the
2382 :     old value (in particular: without having to re-parse the string)
2383 :     - use controls to handle the "overload" keyword in the init group
2384 :     (I believe this change actually fixes a long-standing obscure bug.)

2389 :     Tag: blume-20040927-lazysml
2390 :     Description:
2391 :    
2392 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2393 :     difference to "sml" is that compilation is done with Control.lazysml
2394 :     set to true. A source of class "lazysml" is automatically recognized
2395 :     by a file name suffix of ".lml".
2396 :    
2397 :     In addition to the above feature, the original class "sml" now also
2398 :     supports a tool argument "lazy" which has the same effect. As a
2399 :     result, the following three lines are equivalent:
2400 :    
2401 :     foo.sml : lazysml
2402 :     foo.sml : sml (lazy)
2403 :     foo.sml (lazy)
2404 :    
2405 :     The setting goes into effect both during parsing and during
2406 :     compilation. The original setting is restored right after parsing and
2407 :     after compilation, respectively.
2408 :    
2409 :     In addition to all the above, there is also a general mechanism to set
2410 :     ANY of the "controls" that are available at the command line via
2411 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2412 :     apply as well. (In fact, "lazy" is implemented as a special case of
2413 :     the general mechanism.)
2414 :    
2415 :     The .cm file syntax uses a new keyword tool argument called "with".
2416 :     There are several ways of indicating the desired settings:
2417 :    
2418 :     foo.sml (with:parser.quotations=true)
2419 :     foo.sml (with:(name:parser.quotations value:true))
2420 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2421 :     foo.sml (with:(name1=value1 name2=value2 ...))
2422 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2423 :    
2424 :     etc.
2425 :    
2426 :     Another possible abbreviation is to leave out the =v or value:v part
2427 :     if the name refers to a boolean control (in which case the value is
2428 :     taken to be true). Thus, one could get lazy sml also by saying:
2429 :    
2430 :     foo.sml (with:parser.lazy-keyword=true)
2431 :     foo.sml (with:parser.lazy-keyword)
2432 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2433 :     foo.sml (with:(name:parser.lazy-keyword))

2785 :     Description:
2786 :    
2787 :     Changed the interface of structures Timer and Unix to match the most
2788 :     recent Basis spec.
2789 :    
2790 :     In the case of Unix there still seems to be an open/weird issue:
2791 :    
2792 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2793 :     fresh streams whenever they are called -- as opposed to have them
2794 :     return the same stream every time. This design is supposed to
2795 :     prevent space leaks caused by proc values hanging on to streams.
2796 :    
2797 :     The reap function, on the other hand, is supposed to close the
2798 :     streams. This cannot be done without having a handle on the
2799 :     stream in proc after all...
2800 :    
2801 :     I took the liberty to implement the following stopgap solution:
2802 :    
2803 :     The proc value hangs on to the most recently created stream(s).
2804 :     Reap closes those. If either or both of the two streams hadn't
2805 :     been created at all yet, then reap will close the corresponding
2806 :     file descriptors directly.
2807 :    
2808 :     PS: I don't understand the original space leak argument anymore. If
2809 :     a proc hangs on to the imperative stream, then I/O operations on those
2810 :     will advance the state of the cached stream and avoid the space leak.

2823 :     Tag: blume-20040525-group-owner
2824 :     Description:
2825 :    
2826 :     CM now ignores (but still accepts) the "owner" information in group
2827 :     descriptions. The owner of a group is its next enclosing
2828 :     library. Each group must have a unique owner. (There is a virtual
2829 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2830 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2831 :     and CM would check that such a declaration is correct. The new scheme
2832 :     is to have CM check that for each group there is precisely one owning
2833 :     library.
2834 :    
2835 :     The advantage of the new scheme is that the programmer no longer needs
2836 :     to maintain the somewhat annoying owner information. The downside is
2837 :     that CM cannot enforce the ownership rule across multiple runs of
2838 :     CM.make. Fortunately, enclosing the same group in two different
2839 :     libraries A and B which are not part of the same program does not
2840 :     cause real problems.

2861 :     Arranged for ml-build to clean up after itself a little bit better.
2862 :     The script generates a temporary SML source file and compiles it using
2863 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
2864 :     gets rid of those at the end, so they don't accumulate under .cm.
2865 :    
2866 :     This required a minor change to install.sh because the name of the

2892 :    
2893 :     Hi,
2894 :    
2895 :     Attached to this email you find a diff against sml/nj 110.45
2896 :     that will enable socket support under Windows.
2897 :    
2898 :     To apply the patch (using unix or cygwin)
2899 :     1) gunzip runtime.diff.gz
2900 :     2) "cd" into "src/runtime" in the source tree of a fresh
2901 :     110.45 installation.
2902 :     3) patch -p 1 < [your/path/to]runtime.diff
2903 :    
2904 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2905 :     I only ran a few tests for basic socket client functionality
2906 :     (which worked fine). Especially the functions that use ioctl
2907 : mblume 1490 are not tested at all and might not work (see below).
2908 :    
2909 :     I implemented this since we want to move to a newer version of sml/nj
2910 :     but need socket support in order to use it. This is the first time I
2911 :     even had a look at the sml/nj source, so please review my changes
2912 :     before making this part of the distribution! Here are a few issues
2913 : blume 2155 that I think might be better for someone to solve who is more
2914 : mblume 1490 familiar with the sml/nj source (and socket programming):
2915 :    
2916 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2917 :     exception since I could not figure out what the windows equivalent
2918 :     of these functions is
2919 :    
2920 :     - In sockets-osdep.h there are a some #include statements that are
2921 :     only used in a few files that include sockets-osdep.h
2922 :    
2923 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2924 :     does not process its return value since I don't know how to
2925 :     report an error upwards.
2926 :    
2927 :     - It would probably be good to have a call to WSACleanup() when
2928 : blume 2155 the library is unloaded (if there is such a possibility).
2929 : mblume 1490 Otherwise I think Windows will take care of this automatically
2930 :     when the process finishes.
2931 :    
2932 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2933 :     no idea if that is actually the proper replacement on Windows.
2934 :    
2935 :     - All these issues are marked in the code by "FIXME" comments.
2936 :    
2937 : blume 2155 We use sml/nj extensively in our products and are quite happy
2938 :     with it. I hope this contribution will help you.
2939 : mblume 1490
2940 :     Keep up the good work!
2941 :

3017 :     Description:
3018 :    
3019 :     Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
3020 :     of SML/NJ. The problem is that
3021 :    
3022 :     lib = dlopen(NULL, ...)
3023 :     f = dlsym(lib, "malloc");
3024 :    
3025 : blume 2155 does not work on Windows unless we explicitly export symbols
3026 :     such as 'malloc' during linking. We fixed this by explicitly
3027 : allenleung 1468 exporting the required symbols with the magic gcc incantation:
3028 :    
3029 :     -Wl,--export-all cygwin.def
3030 :    
3031 :     where cygwin.def is a file containing all the symbols that
3032 : blume 2155 we wish to export.
3033 : allenleung 1468
3034 : blume 2155 I suspect this is a Windows problem and we'll have to
3035 :     do the same (somehow with windows compilers) when
3036 : allenleung 1468 we build the native win32 version with the system
3037 : blume 2155 calls LoadLibrary/GetProcAddress.

3162 :     Tag: blume-20030926-ppautoload
3163 :     Description:
3164 :    
3165 :     I modified the read-eval-print loop so that the autoloader gets
3166 :     invoked whenever the prettyprinter tries to look up a symbol that
3167 :     is not currently defined in the toplevel environment but which
3168 :     appears in CM's autoload registry. As a result, we see far fewer of
3169 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3170 :    
3171 :     In addition to this I tried to clean up some pieces of the Basis
3172 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3173 :     instances of these ?.Foo.Bar.xxx names from being printed.
3174 :    
3175 :     The mechanism that picks names for types still needs some work, though.
3176 :     (Right now it seems that if there is a type A.t which is defined to
3177 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3178 :     "?.B.u" although the perhaps more sensible solution would be to use
3179 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3180 :     a chain of DEFtycs not farther than there are corresponding toplevel
3181 :     names in the current environment.)

3187 :     Description:
3188 :    
3189 :     Another installer tweak: All the ML code for the installer is now
3190 :     compiled during CMB.make and put into a little library called
3191 :     $smlnj/installer.cm. The installation then simply invokes
3192 :    
3193 :     sml -m $smlnj/installer.cm
3194 :    
3195 :     and everything happens automagically.
3196 :    
3197 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3198 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3199 :     and BINDIR.
3200 :    
3201 :     The new scheme guarantees that the ML code responsible for the installation
3202 :     is in sync with the APIs of the main system. Also, the installer is
3203 :     somewhat faster because the installer script is precompiled.

3220 :     Tag: blume-20030924-sockets
3221 :     Description:
3222 :    
3223 :     1. Fixed SOCKET API and implementation to match Basis spec.
3224 :     This required changing the internal representation of sockets to one
3225 :     that remembers (for each socket file descriptor) whether it is currently
3226 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3227 :     call is made only if the state actually needs to change).
3228 :    
3229 :     2. OS-specific details of sockets were moved into separate files, thus
3230 :     making it possible to unify the bulk of the socket implementations
3231 :     between Unix and Win32.
3232 :    
3233 :     3. CML's socket API changed accordingly.
3234 :     (Note that we need to remove non-blocking functions from this API
3235 :     since they are redundant in the case of CML!)
3236 :    
3237 :     4. CML's socket implementation now makes use of non-blocking functions
3238 :     provided by Basis, thus removing all OS-dependent code from this part
3239 :     of CML.
3240 :    
3241 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3284 :     1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
3285 :     this seems to be controversial at the moment) and used those in
3286 :     Posix.ProcEnv.times.
3287 :    
3288 :     2. Added Time.{from,to}Nanoseconds to Time.
3289 :    
3290 :     3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
3291 :     For example, fromLargeInt never needs to look at more than 3 "big
3292 :     digits" to get its 53 bits of precision.

3298 :     Description:
3299 :    
3300 :     Added an entry to the primitive environment
3301 :     (compiler/Semant/statenv/prim.sml) for int32->real64 conversion and
3302 :     added code to compiler/CodeGen/main/mlriscGen.sml to implement it.
3303 :    
3304 :     Removed some of the "magic" constants in real64.sml and replaced them
3305 :     with code that generates these values from their corresponding
3306 :     integer counterparts.
3307 :    
3308 :     Made all(?) the slice-related changes to the Basis and made everything
3309 :     compile again...

3353 :     Tag: blume-20030909-installer
3354 :     Description:
3355 :    
3356 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3357 :     Modified config/install.bat to take advantage of it. Also modified
3358 :     config/install.sh (and called it config/new-install.sh) to take advantage
3359 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3360 :     independent.)
3361 :    
3362 :     The installer can now install everything under Win32
3363 :     as well as under *nix as long as it compiles.
3364 :    
3365 :     Other changes:
3366 :    
3367 :     - made CML compile again under Win32
3368 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3369 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3370 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3371 :     same as type int; under Win32 it isn't
3372 :     - fixed some slice-related problems in the win32-specific parts of CML
3373 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3374 :     (under Win32, the volume name is case-insensitive, and the
3375 :     OS.Path code compares volume names for equality)

3384 :     when given an empty string. This is what the spec says, and incidentally,
3385 :     CM depends on it. (CM otherwise goes into an infinite loop in certain
3386 :     cases when presented with the name of a non-existing .cm file.)

3391 : mblume 1352 Tag: blume-20030905-slices-etc
3392 : mblume 1350 Description:
3393 :    
3394 :     1. Changed interface to vectors and arrays in Basis to match
3395 :     (draft) Basis spec.
3396 :     2. Added signatures and implementations of slices according to
3397 :     Basis spec.
3398 :     3. Edited source code throughout the system to make it compile again
3399 :     under 1. and 2. (In some cases code had to be added to have it
3400 :     match the new signatures.)
3401 :     4. MLRISC should be backward-compatible: the copies of the originals
3402 :     of files that needed to change under 3. were retained, the .cm files
3403 :     check the compiler version number and use old versions when
3404 :     appropriate.
3405 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3406 :     dirstream -> string option (in accordance with Basis spec).
3407 :     6. When generating code that counts lines, ml-lex used function
3408 :     CharVector.foldli, taking advantage of its old interface.
3409 :     This has been replaced with the corresponding code from
3410 :     CharVectorSlice. (html-lex must be re-lexed!)
3411 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3412 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3413 :     8. Removed temporary additions (fromInternal, toInternal) from the
3414 :     (now obsolete) IntInf in smlnj-lib/Util.
3415 :     9. Cleaned up structure Byte.
3416 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3417 :     Cleaned/corrected implementation of Date.
3418 :     (Still need to check for correctness; implement better canonicalizeDate.)
3419 :     11. Added "scan" to signature IEEE_REAL.
3420 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3421 :     mod and rem when second operand is 2 (for parity checks).]
3422 :     13. Changed representation of type Time.time, using a single IntInf.int
3423 :     value counting microseconds. This considerably simplified the
3424 :     implementation of structure Time. We now support negative time
3425 :     values; scan and fromString handle signs.
3426 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3427 :     ArraySlice).

3432 :     Tag: blume-20030828-intinf
3433 :     Description:
3434 :    
3435 :     This is a major update which comes with a version number bump
3436 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3437 :     and an implementation of IntInf in the Basis.
3438 :    
3439 :     There are a fairly large number of related changes and updates throughout
3440 :     the system:
3441 :    
3442 :     Basis:
3443 :     - Implemented IntInf.
3444 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3445 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3446 : mblume 1347 - Added FixedInt as a synonym for Int32.
3447 :    
3448 :     compiler:
3449 :     * Added support for a built-in intinf type.
3450 :     - literals
3451 :     - pattern matching
3452 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3453 :     - overloading on literals and operations
3454 :    
3455 :     This required adding a primitive type intinf, some additional
3456 :     primops, and implementations for several non-trivial intinf
3457 :     operations in Core. (The intinf type is completely abstract
3458 :     to the compiler; all operations get delegated back to the Core.)
3459 :    
3460 :     * Intinf equality is handled by polyequal. However, the compiler
3461 :     does not print its usual warning in this case (since polyequal
3462 :     is the right thing to do there).
3463 :    
3464 :     * Improved the organization of structure InlineT.
3465 :    
3466 :     * A word about conversion primops:
3467 :     If conversions involving intinf do not cancel out during
3468 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3469 : mblume 1347 Since all core access must be resolved already during the FLINT
3470 :     translate phase, it would be too late a the time of CPS contract
3471 : mblume 1348 to add new Core calls. For this reason, conversion primops
3472 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3473 :     they are supposed to convert, and 2. the Core function that
3474 :     can help with this conversion if necessary. If CPS contract
3475 : mblume 1348 eliminates a primop, then the associated Core function becomes
3476 :     dead and goes away. Intinf conversion primops that do not get
3477 :     eliminated by CPS contract get rewritten into calls of their
3478 :     core functions by a separate, new phase.
3479 : mblume 1347
3480 :     interactive system:
3481 :     - Control.Print.intinfDepth controls max length of intinf constants
3482 :     being printed. (Analogous to Control.Print.stringDepth.)
3483 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3484 :     duplicates; replaced some of the code with code that makes better
3485 :     use of library functionality.
3486 :    
3487 :     CM:
3488 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3489 :     are no longer silent.
3490 :    
3491 :     CKIT:
3492 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3493 :     in favor of LargeInt -- which is now the same as IntInf.
3494 :     CKIT-knowledgable people should check whether this is what's
3495 :     intended and otherwise change things back to using Int32 or
3496 :     FixedInt.
3497 :    
3498 :     Throughout the code:
3499 : mblume 1348 Started using IntInf.int literals and built-in operations
3500 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3519 :     Tag: blume-20030811-windows
3520 :     Description:
3521 :    
3522 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3523 :    
3524 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3525 :    
3526 :     This patch restores SML/NJ's ability to run under win32. There are a
3527 :     number of changes, including fixes for several bugs that had gone
3528 :     unnoticed until now:
3529 :    
3530 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3531 :     trying to run the win32 version from within cygwin.)
3532 :    
3533 :     - There are a number of simple .bat scripts that substitute for their
3534 :     corresponding Unix shell-scripts. (See below.)
3535 :    
3536 :     - The internals of ml-build have been modified slightly. The main
3537 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3538 :     using OS.Process.system, the ML process delegates this task back
3539 :     to the script. Otherwise problems arise in mixed environments such
3540 :     as Cygwin where scripts look and work like Unix scripts, but
3541 :     where OS.Process.system cannot run them.
3542 :    
3543 :     - In CM, the srcpath pickler used native pathname syntax -- which
3544 :     is incorrect in the case of cross-compilation. The new pickle format
3545 :     is independent of platform-specific naming conventions.
3546 :    
3547 :     - Path configuration files (such as lib/pathconfig) can now choose
3548 :     between native and standard syntax. Placing a line of the form
3549 :    
3550 :     standard!
3551 :    
3552 :     into the file causes all subsequent paths to be interpreted using
3553 :     CM standard pathname syntax (= Unix conventions); a line
3554 :    
3555 :     native!
3556 :    
3557 :     switches back to native style. This was needed so that
3558 :     path config files can be written portably, see src/system/pathconfig.
3559 :    
3560 :     - Runtime system:
3561 :    
3562 :     - win32-filesys.c: get_file_time and set_file_time now
3563 :     access modification time, not creation time.
3564 :    
3565 :     - I/O code made aware of new array representation.
3566 :    
3567 :     - Bug fixes in X86.prim.masm.
3568 :    
3569 :     - src/system/makeml made aware of win32. (For use under cygwin
3570 :     and other Unix-environments for windows.)
3571 :    
3572 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3573 :     which caused BinIO.inputAll to fail consistently.
3574 :    
3575 :     .bat scripts:
3576 :    
3577 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3578 :    
3579 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3580 :     applications (sml, ml-yacc, ml-lex).
3581 :     - ml-build.bat: analogous to ml-build.
3582 :     - config\install.bat: Analogous to config/install.sh. This requires
3583 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3584 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3585 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3586 :     and the bootfile hierarchy must have been unpacked under
3587 :     sml.boot.x86-win32.
3588 :     The script is very primitive and does a poor job at error checking.
3589 :     It only installs the base system, ml-lex, and ml-yacc. No other
3590 :     libraries are being installed (i.e., you get only those that
3591 :     are part of the compiler.)
3592 :     - link-sml.bat: analogous to .link-sml, but not currently used
3593 :    
3594 :     Unrelated bug fixes:
3595 :    
3596 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3597 :     types.
3598 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3599 :     otherwise.)

3636 :     Description:
3637 :    
3638 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3639 :    
3640 :     This mainly affects the quality of error messages. However, some
3641 :     of the code is now more straightforward than before. (Treatment of
3642 :     the above four constructs in translate.sml is much simpler than
3643 :     the "macro-expansion" that was going on before. Plus, the mach-
3644 :     compiler no longer gets invoked just to be able to compile an
3645 :     if-expression.)
3646 :    
3647 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3648 :     interactive loop.

3694 :     Description:
3695 :    
3696 :     Fixed a serious bug in the rewrite code for FP spilling/reloading that
3697 :     sent the RA into an infinite loop when floating point registers get
3698 :     spilled. (Because of this bug, e.g., nucleic stopped compiling between
3699 :     110.37 and 110.38.)
3700 :     There was another set of potential problems related to the handling of
3701 :     MLRISC annotations (but those did not yet cause real problems, apparently).

3707 :     Description:
3708 :    
3709 :     Added a call of SrcPath.sync at the beginning of Parse.parse (in CM).
3710 :     This fixes the problem of CM getting confused by files that suddenly
3711 :     change their identity (e.g., by getting unlinked and recreated by some
3712 :     text editor such as vi). There might be a better/cheaper/cleaner way

3728 :    
3729 : blume 1282 In good old tradition, there has been a slight hiccup so that we have
3730 :     to patch 110.42 after the fact. The old release tag has been replaced
3731 :     (see below).
3732 :

3735 :     each other's way.
3736 :

3824 :    
3825 :     Another small change is that ppDec tries to give more information
3826 :     than just "<sig>" in the case of functors. However, this code is
3827 :     broken in some mysterious way if the functor's body's signature
3828 :     has not been declared by ascription but gets inferred from the
3829 :     implementation. This needs fixing...

3898 :    
3899 :     * Removed again all the stuff from config/preloads that one wouldn't
3900 :     be able to preload at the time the initial heap image is built.

3929 :    
3930 :     0. John Reppy made several modifications to the SML/NJ library.
3931 :     In particular, there is a shiny new controls-lib.cm.
3932 :    
3933 :     1. Pushed new controls interface through compiler so that everything
3934 :     compiles again.
3935 :    
3936 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3937 :     SML/NJ library (so that CML compiles again).
3938 :    
3939 :     3. Modified init scripts because XXX_DEFAULT environment variables
3940 :     are no longer with us. (Boot-time initialization is now done
3941 :     using the same environment variables that are also used for
3942 :     startup-time initialization of controls.)

3948 :     Description:
3949 :    
3950 :     All pseudo-ops emitted before the first segment declaration
3951 :     such as TEXT, DATA, and BSS directives are assumed to be global
3952 :     declarations and are emitted first in the assembly file. This is
3953 :     useful in a number of situations where one has pseudo-ops that are not
3954 :     specific to any segment, and also works around the constraint that one
3955 :     cannot have client pseudo-ops in the TEXT segment.
3956 :    
3957 :     Because no segment is associated with these declarations it is
3958 :     an error to allocate any space or objects before the first segment
3959 :     directive and an exception will be raised. However, we cannot make
3960 :     this check for client pseudo-ops.
3961 :    
3962 :     These top level declarations are a field in the CFG graph_info.
3963 :     In theory you can continue to add to this field after the CFG has been
3964 :     built -- provided you know what you are doing;-)

3987 :     Description:
3988 :    
3989 :     Applied the following bugfix provided by Emden Gansner:
3990 :    
3991 :     Output is corrupted when outputSubstr is used rather than output.
3992 :    
3993 : blume 2155 The problem occurs when a substring
3994 : blume 1189
3995 :     ss = (s, dataStart, dataLen)
3996 :    
3997 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3998 :     avail bytes of s, starting at index dataStart, are copied into the
3999 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
4000 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
4001 :     starting this copy at index dataStart+avail in s, the current code
4002 : blume 1189 starts the copy at index avail.
4003 :    
4004 :     Fix:
4005 :     In text-io-fn.sml, change line 695 from
4006 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
4007 : blume 2155 to

4024 :     Description:
4025 :    
4026 :     Added full support for div/mod/rem/quot on the x86, using the machine
4027 :     instruction's two results (without clumsily recomputing the remainder)
4028 :     directly where appropriate.
4029 :    
4030 :     Some more extensive power-of-two support was added to the x86 instruction
4031 :     selector (avoiding expensive divs, mods, and muls where they can be
4032 :     replaced with cheaper shifts and masks). However, this sort of thing
4033 :     ought to be done earlier, e.g., within the CPS optimizer so that
4034 :     all architectures benefit from it.
4035 :    
4036 :     The compiler compiles to a fixed point, but changes might be somewhat
4037 :     fragile nevertheless. Please, report any strange things that you might
4038 :     see wrt. div/mod/quot/rem...

4044 :     Description:
4045 :    
4046 :     Fixed my broken div/mod logic. Unfortunately, this means that the

4048 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
4049 :     The problem was with quotient = 0, because that alone does not tell
4050 :     us which way the rounding went. One then has to look at whether
4051 :     remainder and divisor have the same sign... :(
4052 :

4060 :    
4061 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
4062 :    
4063 :     Primops have changed. This means that the bin/boot-file formats have
4064 :     changed as well.
4065 :    
4066 :     To make sure that there is no confusion, I made a new version.
4067 :    
4068 :    
4069 :     CHANGES:
4070 :    
4071 :     * removed REMT from mltree (remainder should never overflow).
4072 :    
4073 :     * added primops to deal with divisions of all flavors to the frontend
4074 :    
4075 :     * handled these primops all the way through so they map to their respective
4076 :     MLRISC support
4077 :    
4078 :     * used these primops in the implementation of Int, Int32, Word, Word32
4079 :    
4080 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
4081 :    
4082 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
4083 :    
4084 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
4085 :     floating point
4086 :    
4087 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
4088 :     and Real (but Real.abs maps to a separate floating-point-only primop)
4089 :    
4090 :    
4091 :     TODO items:
4092 :    
4093 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
4094 :     instructions because the machine instruction encoder cannot handle
4095 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
4096 :     REM in the first place, and REM is supported by the x86 machine coder.)
4097 :    
4098 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
4099 :     selection phase. (The two can be streamlined because the hardware
4100 :     delivers both quotient and remainder at the same time anyway.)
4101 :    
4102 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
4103 :     (Currently the behavior is inconsistent both across architectures and
4104 :     wrt. the draft Basis spec.)
4105 :    
4106 :     * Word8 should eventually be handled natively, too.
4107 :    
4108 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
4109 :     as if there currently is no execution path that could trigger it in
4110 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
4111 :     hold for things like multiplication and division.)

4117 :     Description:
4118 :    
4119 :     Added support for all four division operations (ML's div, mod, quot,
4120 :     and rem) to MLRISC. In the course of doing so, I also rationalized
4121 :     the naming (no more annoying switch-around of DIV and QUOT), by
4122 :     parameterizing the operation by div_rounding_mode (which can be either
4123 :     DIV_TO_ZERO or DIV_TO_NEGINF).
4124 :    
4125 :     The generic MLTreeGen functor takes care of compiling all four
4126 :     operations down to only round-to-zero div.
4127 :    
4128 :     Missing pieces:
4129 :    
4130 :     * Doing something smarter than relying on MLTreeGen on architectures
4131 :     like, e.g., the x86 where hardware division delivers both quotient and
4132 :     remainder at the same time. With this, the implementation of the
4133 :     round-to-neginf operations could be further streamlined.
4134 :    
4135 :     * Remove inlining support for div/mod/rem from the frontend and replace it
4136 :     with primops that get carried through to the backend. Do this for all
4137 :     int and word types.

4143 :     Description:
4144 :    
4145 :     I improved (hopefully without breaking them) the implementation of Int.div,
4146 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
4147 :     advantage of the following observations:
4148 :    
4149 :     Let q = x quot y r = x rem y
4150 :     d = x div y m = x mod y
4151 :    
4152 :     where "quot" is the round-to-zero version of integer division that
4153 :     hardware usually provides. Then we have:
4154 :    
4155 :     r = x - q * y where neither the * nor the - will overflow
4156 :     d = if q >= 0 orelse x = q * y then q else q - 1
4157 :     where neither the * nor the - will overflow
4158 :     m = if q >= 0 orelse r = 0 then r else r + y
4159 :     where the + will not overflow
4160 :    
4161 :     This results in substantial simplification of the generated code.
4162 :     The following table shows the number of CFG nodes and edges generated
4163 :     for
4164 :     fun f (x, y) = x OPER y
4165 :     (* with OPER \in div, mod, quot, rem *)
4166 :    
4167 :    
4168 :     OPER | nodes(old) | edges(old) | nodes(new) | edges(new)
4169 :     --------------------------------------------------------
4170 :     div | 24 | 39 | 12 | 16
4171 :     mod | 41 | 71 | 12 | 16
4172 :     quot | 8 | 10 | 8 | 10
4173 :     rem | 10 | 14 | 8 | 10
