446 :     will be forced to run regardless of whether or not their targets
447 :     are up-to-date
448 :     - changed installer code so that config/install.sh will re-build
449 :     heap images for all tools even if those heap images already existed

454 :     Description:
455 :    
456 :     After Aaron Turon's bug fix for ml-ulex (handling the ^ character
457 :     in legacy mode), re-ran the lexer generator on all lex input files
458 :     and committed the results.
459 :    
460 :     This should fix the problem with ckit and nlffi that was reported

474 :     Revision: 2650
475 :     Description:
476 :    
477 :     3rd merge of base from primop-branch-3 into the trunk.
478 :     Additional bug fixes included:
479 :    
480 :     * Timer.cpu_timer, etc. type printing corrected (by making
481 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
482 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by

487 :     Date: 2007/05/31 11:40:00 CDT
488 :     Description:
489 :    
490 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
491 :    
492 :     Also, changed the handling of "no core access": When translate.sml
493 :     needs access to a core exception at a time when the core has not
494 :     been set up yet (this only happens when compiling system/smlnj/init/*),
495 :     then don't bother generating the corresponding tests.
496 :    
497 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
498 :     the exception. Unfortunately, that confuses the plambda type checker.
499 :     Moreover, it does not do any good, because at runtime we don't expect
500 :     such an exception to be ever raised. (The code in system/smlnj/init/*
501 :     has to be written very carefully with this in mind!)

513 :     Description:
514 :    
515 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
516 :     with an explicit test for zero division. This should fixes several
517 :     regressions and makes it possible for downstream optimization phases
518 :     to treat these operations as "pure" when they are applied to unsigned
519 :     operands.

525 :    
526 :     Added the new MLRISC code generator for the AMD64. This version,
527 :     in contrast to the previous one, uses SSE registers and instructions
528 :     for all floating-point computations.

533 : jhr 2613 Description:
534 :    
535 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
536 :     for bugs #1415 and #1416. We also now correctly handle format characters that
537 :     lie outside the specified set.

541 :     Date: 2007/05/23 22:30:00 CDT
542 :     Description:
543 :    
544 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
545 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
546 :    
547 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
548 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
549 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
550 :     while running CMB.make. The point is that the single symbol
551 :     NO_PLUGINS is definde in all three cases.)
552 :    
553 :     I changed the three locations within the sources that get compiled
554 :     during CMB.make where ml-yacc or ml-lex input is processed: When
555 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
556 :     is bypassed.
557 :    
558 :     When bootstrapping new versions of the compiler, there can be
559 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
560 :     are not available or otherwise not operational. In this case one can
561 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
562 :     do so, the following command should be issued at the interactive
563 :     prompt:
564 :    
565 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
566 :    
567 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
568 :     files that normally would be generated by ml-yacc and ml-lex.
569 :     (Copies of these files are in the repository.)

577 :     2nd merge of base from primop-branch-3 into the trunk.

585 :     Description:
586 :    
587 :     Changed the installation mechanism for CM tool plugins. These are
588 :     just libaries and now get installed like ordinary libaries.
589 :    
590 :     There are now a number of new installation targets that give some
591 :     fine-grain control over what classes and suffixes are known, and what
592 :     they will map to.
593 :     See config/targets for details.
594 :    
595 :     The code that caused plugin installation as part of running a
596 :     tool's "build" script has been removed. (The build script is for
597 :     building, not for installing.)

601 : blume 2578 Date: 2007/05/22 11:50:00 CDT
602 :     Description:
603 :    
604 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
605 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
606 :     CM fail if a shell tool reports a non-success exit status. If
607 :     the control is set to true, then CM will press on after tool failures
608 :     in the event that the target files exist (even though they are
609 :     considered outdated). Turning the control to true can be useful for
610 :     bootstrapping.

614 :     Date: 2007/05/19
615 :     Description:
616 :    
617 :     Merge of ml-lpt revisions for 110.64.
618 :    
619 :     The name of several ml-lpt-lib modules has changed:
620 :     Repair => AntlrRepair
621 :     StreamPos => AntlrStreamPos
622 :     ErrHandlerFn => AntlrErrHandler
623 :     EBNF => AntlrEBNF
624 :    
625 :     The ml-antlr specification format has changed: declarations such as
626 :     %tokens and nonterminal definitions can occur *multiple* times in the
627 :     same specification. The semantics are such that each new declaration
628 :     extends the previous ones. This does not apply to %start or %name,
629 :     of course.
630 :    
631 :     Importing a grammar via %import now includes *all* declarations in from
632 :     the imported grammar, except for %name, %entry, and %start. Tokens
633 :     and nonterminals can be dropped using the new %dropping clause of the
634 :     %import directive; the separate %drop and %extend have been removed.
635 :    
636 :     We now allow optional type annotations on nonterminals, using the %nonterms
637 :     directive as in ml-yacc.
638 :    
639 :     The refcell construct is now implemented using SML's regular reference
640 :     cells, so the :== and !! notation has been deprecated.
641 :    
642 :     The ml-antlr tool now does much more checking of specifications, and
643 :     its error messages have been greatly improved. Error repair for
644 :     generated parsers has been completely rewritten, and is now both
645 :     much faster and more accurate.
646 :    
647 :     ml-ulex is now more lenient with escape codes (non-SML-standard
648 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
649 :     Also, character classes may now include a "-" character at the beginning
650 :     as is standard in most other regexp tools.
651 :    
652 :     All of these changes are documented in the user guide, which has
653 :     been updated and improved with this merge.

805 :    
806 :     Added preliminary support in MLRISC for Staged Allocation, a technique
807 :     for specifying calling conventions (see
808 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
809 :     Initially, we plan to use this code to generate C calls for the AMD64.
810 :    
811 :     The staged allocation code base resides in MLRISC/staged-allocation,
812 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

876 :     Date: 2007/01/31
877 :     Description:
878 :    
879 :     Brought ml-lpt manual up-to-date with the code. Many minor
880 :     improvements to the tools, and a few minor bugfixes. Prepared
881 :     ml-lpt-lib for integration with new UTF8 structure. Changed
882 :     the interface for creating streams in ml-ulex (we now support
883 :     stream creation from several kinds of sources). Overall, the
884 :     tools are now quite stable, and their interfaces are unlikely to
885 :     change in a way that would break compatibility. More work,
886 :     however, is needed in the documentation.

891 :     Description:
892 :    
893 :     Implemented library installer. Moved CM plugin code for
894 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
895 :     their respective trees. Implemented CM plugin for ml-ulex
896 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
897 :     and ml-antlr.
898 :    
899 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
900 :     CM tools. (It turns out to be too messy to do otherwise because
901 :     there is too much code that during installation relies on the presence
902 :     of these tools -- resulting in a tricky ordering problem.)

907 :     Description:
908 :    
909 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
910 :     Modified CM's startup code to use shiftArgs as it processes
911 :     command line arguments. This way, the init code in each .sml-file
912 :     or library that is mentioned at the top level will see only
913 :     those arguments that have not yet been processed at this point.
914 :     In other words, the init code can "seize control" and process the
915 :     remaining command line.

971 :     Description:
972 :    
973 :     Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to
974 :     get the c_cc termios data copied correctly. Also moved the allocation

981 :     Date: 2006/12/08 09:50:00 CST
982 :     Description:
983 :    
984 :     Added code to CM's "standard shell tool" implementation which
985 :     causes it to tolerate (with a warning) the situation where the shell
986 :     command fails (e.g., due to the shell command's non-existence)
987 :     as long as all target files exist.
988 :    
989 :     This makes it possible to, e.g., build ml-yacc from sources even if
990 :     svn checkout messed up the time stamps on files in such a way that
991 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
992 :     be needed to re-process yacc.grm, but obviously it might not yet be
993 :     available at that time.)

999 :    
1000 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
1001 :     recvVecFromNB' in the SOCKET signature. This error is actually
1002 :     in the SML Basis specification too.

1031 : blume 2193 Date: 2006/11/09 14:30:00 CST
1032 :     Tag: release-110.60
1033 :     Description:
1034 :    
1035 :     New working release (110.60). NEW BOOTFILES!
1036 :    
1037 :     This is the first subversion-hosted release. There are also changes
1038 :     to the directory layout. Here is a table:
1039 :    
1040 :     (All pathnames are relative to the SML/NJ "root" directory.)
1041 :    
1042 :     config -> config
1043 :    
1044 :     src/cm -> base/cm
1045 :     src/compiler -> base/compiler
1046 :     src/runtime -> base/runtime
1047 :     src/system -> base/system
1048 :    
1049 :     src/cm/pgraph -> pgraph
1050 :    
1051 :     src/READMES -> base/READMES
1052 :     src/$notefile -> base/NOTES/$notefile
1053 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1054 :     MACOSXINSTALL WININSTALL
1055 :    
1056 :     src/smlnj-lib -> smlnj-lib
1057 :     src/MLRISC -> MLRISC
1058 :     ckit -> ckit
1059 :     src/cml -> cml
1060 :     src/eXene -> eXene
1061 :     src/heap2asm -> heap2asm
1062 :     src/lexgen -> lexgen
1063 :     src/ml-burg -> ml-burg
1064 :     src/ml-lex -> ml-lex
1065 :     src/ml-yacc -> ml-yacc
1066 :     src/ml-nlffi-lib -> nlffi/lib
1067 :     src/ml-nlffigen -> nlffi/gen
1068 :     src/smlnj-c -> smlnj-c
1069 :     src/tools/TraceDebugProf -> trace-debug-profile
1070 :    
1071 :     In addition, there is also a new
1072 :    
1073 :     ml-lpt
1074 :    
1075 :     directory containing two new program generator tools: ml-ulex and
1076 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1077 :     LL(k) parser generator). These tools are currently "beta-quality"
1078 :    
1079 :     The latest versios of the sources can now be obtained anonymously
1080 :     via subversion. For this, it is useful to first check out
1081 :    
1082 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1083 :    
1084 :     and put the resulting directory on your shell's PATH. This provides
1085 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
1086 :     and refresh-all.sh.
1087 :    
1088 :     To create a freshly checked-out copy of the sources, do
1089 :    
1090 :     checkout-all.sh [dir]
1091 :    
1092 :     where dir is the optional SML/NJ root directory (default is ".").
1093 :    
1094 :     This creates the above directory layout. Each subdirectory of
1095 :     the root is under individual subversion control. The stat-all.sh
1096 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
1097 :     each of these subtrees.

1100 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
1101 : blume 2155 Date: 2006/11/02 12:20:00 CST
1102 :     Description:
1103 :    
1104 :     Reorganized directory layout.
1105 :    
1106 :     This is a temporary solution, more reorganization is to come.
1107 :    
1108 :     The basic idea is to have a number of toplevel trees, each corresponding
1109 :     to a well-defined part of the overall system. Each part can be
1110 :     maintained individually, even in separate source repositories,
1111 :     although currently we still serve everything out of the main
1112 :     smlnj-gforge tree.
1113 :    
1114 :     Installer and and scripts have been updated to reflect the new
1115 :     layout. The installer (base/src/system/smlnj/installer) is now
1116 :     "scriptable" to avoid burning too much knowledge about the
1117 :     layout into SML source code. The main script used by the installer
1118 :     is in config/actions.
1119 :    
1120 :     The main change is that many of the subdirectories of what used to
1121 :     be known as "src" have moved to the toplevel. The "src" directory
1122 :     itself has moved down into a subtree called "base". (We may eventually
1123 :     get rid of the extra level of indirection represented by "src".)
1124 :    
1125 :     The layout is now as follows:
1126 :    
1127 :     toplevel tree name | default repository
1128 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1129 :     -------------------+----------------------------------------------------
1130 :     config | $gf/config/trunk
1131 :     |
1132 :     base | $gf/sml/trunk
1133 :     |
1134 :     smlnj-lib | $gf/smlnj-lib/trunk
1135 :     MLRISC | $gf/MLRISC/trunk
1136 :     |
1137 :     ml-yacc | $gf/ml-yacc/trunk
1138 :     ml-lex | $gf/ml-lex/trunk
1139 :     ml-burg | $gf/ml-burg/trunk
1140 :     lexgen | $gf/lexgen/trunk
1141 :     heap2asm | $gf/heap2asm/trunk
1142 :     |
1143 :     cml | $gf/cml/trunk
1144 :     eXene | $gf/eXene/trunk
1145 :     ckit | $gf/ckit/trunk
1146 :     nlffi | $gf/nlffi/trunk
1147 :     |
1148 :     smlnj-c | $gf/smlnj-c/trunk
1149 :    
1150 :     In $gf/admin there are a few useful shell scripts for checking out
1151 :     and maintaining the entire collection of trees:
1152 :    
1153 :     admin/checkout-all.sh [dir]
1154 :     -- optionally creates dir and checks out all trees from their
1155 :     default repositories; if dir is missing, checkout into .
1156 :     admin/refresh-all.sh [dir]
1157 :     -- looks at all trees (from the above list) in dir (default: .)
1158 :     and runs "svn update" if the tree exists and is under
1159 :     subversion control;
1160 :     non-existing or non-subversion trees are skipped
1161 :     admin/stat-all.sh [dir]
1162 :     -- like refresh-all.sh, but runs "svn stat" instead

1293 :     kernels dropped.

1309 :    
1310 :     Hooked code for Darwin-specific Intel ABI into main compiler.
1311 :     (This is a temporary solution which relies on the fact that the
1312 :     compiler itself does not use NLFFI. Eventually we need to divorce
1313 :     intel mac from generic x86 unix code and make separate sets of binaries.)

1342 :     Description:
1343 :    
1344 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1345 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1346 : blume 2155 at the time when config/preloads is processed, the library has to
1347 : mblume 1878 be referred to by another name. In 110.57 this would be
1348 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1349 :     to be valid as well.)

1405 :     Description:
1406 :    
1407 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1408 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1409 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1410 :     it. Instead, it has the status of "user code", so it should use
1411 :     $/basis.cm to refer to the Basis library. (At least that's true for
1412 :     the purpose of bootstrapping the previous change. In the future it
1413 :     might make sense to have versiontool.cm refer to
1414 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1415 :     compiler itself uses.)
1416 :    
1417 :     Also patched src/system/testml to have it activate those extra anchor
1418 :     bindings in config/extrapathconfig.

1423 :     Tag: blume-22051115-libraries
1424 :     Description:
1425 :    
1426 :     This change affects the way the following libraries are tied into
1427 :     the system:
1428 :    
1429 :     $/basis.cm
1430 :     $/smlnj-lib.cm
1431 :     $/pp-lib.cm
1432 :     $/controls-lib.cm
1433 :     $/html-lib.cm
1434 :     $/ml-yacc-lib.cm
1435 :    
1436 :     These libraries are now internally (as seen from the source code
1437 :     of the implementation itself) known by the following names:
1438 :    
1439 :     $smlnj/basis/basis.cm
1440 :     $smlnj/smlnj-lib/smlnj-lib.cm
1441 :     $smlnj/smlnj-lib/pp-lib.cm
1442 :     $smlnj/smlnj-lib/controls-lib.cm
1443 :     $smlnj/smlnj-lib/html-lib.cm
1444 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1445 :    
1446 :     This makes it possible to work with code that requires different
1447 :     versions of these libraries, and which refers to these libraries using
1448 :     their "default" names (i.e., the first set of names above). In other
1449 :     words, one can un-define or re-define those default names without
1450 :     compromising the proper functioning of the compiler itself.
1451 :    
1452 :     A similar procedure had already been performed for several of the
1453 :     MLRISC libraries that are linked into the compiler. I did some
1454 :     cleanup on this code.
1455 :    
1456 :     A new file in the config directory (named extrapathconfig) is
1457 :     responsible for setting up path anchors that the compiler itself does
1458 :     not need, but that are typically required by user code.

1638 :     Description:
1639 :    
1640 :     Added mechanism for re-creating a heap file for the interactive system
1641 :     after configuration variables have been changed.
1642 :    
1643 :     CM.redump_heap : string -> unit
1644 :    
1645 :     This is much like SMLofNJ.exportML, but starting from the resulting
1646 : blume 2155 heap does not return to the caller of CM.redump_heap but
1647 : mblume 1792 restarts the interactive system from scratch. The original call of
1648 :     CM.redump_heap does not return but ends the interactive session.
1649 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1650 :    
1651 :     Internally, redump_heap winds the dynamic execution context back to
1652 :     the point where the original heap image was created and re-executes
1653 :     the heap image generation code in the boot code.

1695 :     Description:
1696 :    
1697 :     Fixed serious bug (brown paper bag variety) in new implementation of
1698 :     structure Atom in CML. (I had accidentally used a mailbox instead of
1699 :     an mvar, leaving the door open for races.)

1713 :     Description:
1714 :    
1715 :     Brought back SMLofNJ.Susp. The underlying suspension type is the one
1716 :     implemented in Core -- which means that it is the same as the one used
1717 :     by the lazy extension.

1769 :     Tag: blume-20050114-heap2exec
1770 :     Description:
1771 :    
1772 :     Implemented new (but still experimental) heap2exec facility. This is
1773 :     tested under Mac OS X and should work under Linux (will test shortly).
1774 :     It will probably also work on the Sparc (will test some time later).
1775 :    
1776 :     - removed old "HACKED_STANDALONE" hack from runtime
1777 :    
1778 :     To be able to test this, uncomment the request for "heap2asm" in
1779 :     config/targets prior to installation. (Notice that this is different
1780 :     from "heap2exec" mentioned below. Not a typo.)
1781 :    
1782 :     To perform an actual test, run the command
1783 :    
1784 :     $ bin/heap2exec heapfile execfile
1785 :    
1786 :     (You can put heap2exec on your shell's path.)
1787 :    
1788 :     For example, run
1789 :    
1790 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1791 :    
1792 :     This will create a standalone executable called "mly" which you can
1793 :     then invoke directly as a command.

1819 :     data structure access seems to work.)
1820 :    
1821 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1822 :     (On the Mac, it is big-endian. And that's currently our only
1823 :     PPC platform.)

1938 :     Tag: blume-20041124-position
1939 :     Description:
1940 :    
1941 :     The compiler can now be compiled in a mode that makes structure Position
1942 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1943 :     for the time being.
1944 :    
1945 :     To enable 64-bit positions, use the following procedure:
1946 :    
1947 :     1. Start sml
1948 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1949 :     3. Type
1950 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1951 :     4. Run CMB.make() as usual.
1952 :    
1953 :     This is barely tested. The only test so far was a little SML program
1954 :     counting the number of characters in an 8-gigabyte file by
1955 :     reading it character-by-character. That test was successful.
1956 :    
1957 :     In support of 64-bit positions, a number of new functions have been
1958 :     added to the runtime system.

2002 :     The date string is generated at bootstrap time (during makeml).
2003 :    
2004 :     - In a previous commit, fixed a minor issue with how polyequal is being
2005 :     translated. In particular, the code now "looks through" abstractions.
2006 :     This results in slightly fewer polyEqual warnings and hopefully slightly
2007 :     more efficient code. Important examples for where this matters are
2008 :     the new int64 and word64 types.

2025 :     All the pieces of Word64 are now there, with the exception of the
2026 :     conversions from and to LargeWord. (Eventually these need to be identities,
2027 :     but for the time being they don't even make sense because LargeWord is
2028 :     32-bit wide.)
2029 :    
2030 :     Also started to add similar support for Int64, but major pieces of that
2031 :     are still missing.

2037 :     Description:
2038 :    
2039 :     Structure Word64 is now (almost) complete, word literals and patterns
2040 :     seem to work. There are a few odd pieces missing. In particular,
2041 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2042 :     at the moment.
2043 :    
2044 :     Making Word64 official would mean that LargeWord becomes Word64. But
2045 :     this requires extreme care because most word-word conversions have to
2046 :     go through LargeWord, so making a mistake means loss of efficiency or
2047 :     worse. Eventually there will be a solution similar to (but actually
2048 :     simpler than) what I did with IntInf.

2077 :    
2078 :     Also:
2079 :    
2080 :     - Changend config/srcarchiveurl from a file just
2081 :     containing the URL string into a file containing
2082 :     shell script code. The code has access to the $VERSION variable.
2083 :     - Made corresponding changes to config/install.sh and config/unpack.
2084 :     - Default contents of config/srcarchiveurl uses $VERSION and
2085 :     normally does not have to be edited to reflect a version change.
2086 :    
2087 :     (As a result, a version change can be done by just editing
2088 :     config/version, the rest is now automatic.)

2104 :    
2105 :     This is the HISTORY entry for two earlier commits, both concerning
2106 :     the x86 c-calls code in MLRISC:
2107 :    
2108 :     - added a missing LOAD in the code that deals with struct arguments
2109 :     - made sure the caller does not add the wrong number of bytes to the
2110 :     stack pointer after a call of a function returning a struct
2111 :     (the callee already pops the implicit argument which points to
2112 :     the space reserved for the result)

2128 :     Tag: blume-20041020-standalone-backtrace
2129 :     Description:
2130 :    
2131 :     Added a mechanism for getting back-trace information from standalone
2132 :     programs. Here is how it works:
2133 :    
2134 :     1. The part of the program from which you want to get backtrace
2135 :     information (usually the whole program) should be wrapped with
2136 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
2137 :     main program could be modified from something like
2138 :    
2139 :     fun main (pgm, args) = ...
2140 :    
2141 :     to
2142 :    
2143 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2144 :    
2145 :     2. To be able to access BackTrace.monitor, you have to add
2146 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
2147 :     main function.
2148 :    
2149 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2150 :     CM might have created in the past for your project).
2151 :    
2152 :     4. Build the system using this command line:
2153 :    
2154 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2155 :     myprog.cm MyProg.main myprog
2156 :    
2157 :     instead of the usual
2158 :    
2159 :     ml-build myprog.cm MyProg.main myprog
2160 :    
2161 :     I changed a library name:
2162 :    
2163 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2164 :    
2165 :     New libraries:
2166 :    
2167 :     $smlnj-tdp/back-trace.cm
2168 :     -- when loaded causes the back-trace plugin to be installed
2169 :     $smlnj-tdp/coverage.cm
2170 :     -- when loaded causes the coverage plugin to be installed

2186 :     Description:
2187 :    
2188 :     * Test coverage tool added!
2189 :     * Further reorganization of tracing-, debugging-, and profiling support:
2190 :    
2191 :     - moved original BTImp -- now called BackTrace -- into a separate
2192 :     library called $/trace-debug-profile.cm
2193 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2194 :     - only the instrumentation mechanism is now left in the compiler proper
2195 :     - BackTrace module is a plugin which is NOT plugged in by default
2196 :     - Coverage module is another such plugin
2197 :    
2198 :     To get the benefits of any of these plugin modules, the code in
2199 :     question must be compiled with tdp instrumentation turned on. This
2200 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2201 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2202 :    
2203 :     Plugins are selected at link time. (Pre-compiled instrumented code
2204 :     can be re-loaded with different plugins in effect.) When an
2205 :     instrumented module is linked, whatever plugins are at that time
2206 :     enabled will come into effect for that module.
2207 :    
2208 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2209 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2210 :     To enable the coverage plugin, load the same library and invoke
2211 :     Coverage.install().
2212 :    
2213 :     Back-traces are generated automatically on uncaught exceptions and
2214 :     when the code in question explicitly invokes BackTrace.trigger().
2215 :    
2216 :     Coverage (and execution frequency-) information must be queried
2217 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2238 :    
2239 :     This is is preparation of using the original back-trace
2240 :     instrumentation for other purposes. "TDP" stands for
2241 :     Trace/Debug/Profile.
2242 :    
2243 :     The control flag controlling whether instrumentation is on or off is now
2244 :     registered under a different name, so instead of running sml as
2245 :    
2246 :     sml -Cinstrument.btrace-mode=true

2266 :     Description:

2269 :     treats subsequent occurrences of "group", "library", "source", "is",
2270 :     "*", and "-" as ordinary identifiers rather than keywords.
2271 :    
2272 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool
2273 :     is supposed to accept a tool argument called "source", but this did
2274 :     not work because of the clash with the keyword.

2318 :

2325 : mblume 1639
2326 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2327 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2328 :     Also, loading the versiontool does not work when rebuilding the system
2329 :     because CM is not properly initialized at that time.

2334 :     Tag: blume-20040929-autoversion
2335 :     Description:
2336 :    
2337 :     Implemented some CM magic to have
2338 :     file src/compiler/TopLevel/main/version.sml
2339 :     generated automagically.
2340 :     The version is taken from two files: config/version and config/release.
2341 :     The first is expected to contain a two-part version number such as 110.49.
2342 :     The second should contain a single number, but it may be missing.
2343 :    
2344 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2345 :     time the version tool is loaded (which is the first time you say CMB.make),
2346 :     then the tool will increment the value stored in config/release every
2347 :     time CMB.make is invoked.
2348 :    
2349 :     The binfile format is now insensitive to anything beyond the first
2350 :     two components of a version number, so bumping the release does not render
2351 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2352 :     during development without invalidating existing binfiles.
2353 :    
2354 :     In any case, every CMB.make updates the date information in version.sml.
2355 :     (This is the date that is printed in the banner.)

2368 :     Tag: blume-20040927-controls
2369 :     Description:
2370 :    
2371 :     Added two pieces of functionality to the Controls interface:
2372 :    
2373 :     1. val save'restore: 'a control -> unit -> unit
2374 :    
2375 :     grabs the current value of the control in stage 1 and restores it
2376 :     in stage 2.
2377 :    
2378 :     2. val set' : 'a control * 'a -> unit -> unit
2379 :    
2380 :     stores the given value into the control in stage 2 (i.e., delayed)
2381 :     but does all error checking in stage 1.
2382 :     (This is for string controls that need to do parse their argument --
2383 :     something that might fail. In some cases, notably in CM, one
2384 :     already knows the intended argument but wants to delay the actual
2385 :     assignment until a time when error recovery would be more difficult.)
2386 :    
2387 :     Changed the handling of controls in tool arguments to classes "sml" and
2388 :     "lazysml":
2389 :     - use Controls.save'restore as a more robust way of restoring the
2390 :     old value (in particular: without having to re-parse the string)
2391 :     - use controls to handle the "overload" keyword in the init group
2392 :     (I believe this change actually fixes a long-standing obscure bug.)

2397 :     Tag: blume-20040927-lazysml
2398 :     Description:
2399 :    
2400 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2401 :     difference to "sml" is that compilation is done with Control.lazysml
2402 :     set to true. A source of class "lazysml" is automatically recognized
2403 :     by a file name suffix of ".lml".
2404 :    
2405 :     In addition to the above feature, the original class "sml" now also
2406 :     supports a tool argument "lazy" which has the same effect. As a
2407 :     result, the following three lines are equivalent:
2408 :    
2409 :     foo.sml : lazysml
2410 :     foo.sml : sml (lazy)
2411 :     foo.sml (lazy)
2412 :    
2413 :     The setting goes into effect both during parsing and during
2414 :     compilation. The original setting is restored right after parsing and
2415 :     after compilation, respectively.
2416 :    
2417 :     In addition to all the above, there is also a general mechanism to set
2418 :     ANY of the "controls" that are available at the command line via
2419 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2420 :     apply as well. (In fact, "lazy" is implemented as a special case of
2421 :     the general mechanism.)
2422 :    
2423 :     The .cm file syntax uses a new keyword tool argument called "with".
2424 :     There are several ways of indicating the desired settings:
2425 :    
2426 :     foo.sml (with:parser.quotations=true)
2427 :     foo.sml (with:(name:parser.quotations value:true))
2428 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2429 :     foo.sml (with:(name1=value1 name2=value2 ...))
2430 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2431 :    
2432 :     etc.
2433 :    
2434 :     Another possible abbreviation is to leave out the =v or value:v part
2435 :     if the name refers to a boolean control (in which case the value is
2436 :     taken to be true). Thus, one could get lazy sml also by saying:
2437 :    
2438 :     foo.sml (with:parser.lazy-keyword=true)
2439 :     foo.sml (with:parser.lazy-keyword)
2440 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2441 :     foo.sml (with:(name:parser.lazy-keyword))

2793 :     Description:
2794 :    
2795 :     Changed the interface of structures Timer and Unix to match the most
2796 :     recent Basis spec.
2797 :    
2798 :     In the case of Unix there still seems to be an open/weird issue:
2799 :    
2800 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2801 :     fresh streams whenever they are called -- as opposed to have them
2802 :     return the same stream every time. This design is supposed to
2803 :     prevent space leaks caused by proc values hanging on to streams.
2804 :    
2805 :     The reap function, on the other hand, is supposed to close the
2806 :     streams. This cannot be done without having a handle on the
2807 :     stream in proc after all...
2808 :    
2809 :     I took the liberty to implement the following stopgap solution:
2810 :    
2811 :     The proc value hangs on to the most recently created stream(s).
2812 :     Reap closes those. If either or both of the two streams hadn't
2813 :     been created at all yet, then reap will close the corresponding
2814 :     file descriptors directly.
2815 :    
2816 :     PS: I don't understand the original space leak argument anymore. If
2817 :     a proc hangs on to the imperative stream, then I/O operations on those
2818 :     will advance the state of the cached stream and avoid the space leak.

2831 :     Tag: blume-20040525-group-owner
2832 :     Description:
2833 :    
2834 :     CM now ignores (but still accepts) the "owner" information in group
2835 :     descriptions. The owner of a group is its next enclosing
2836 :     library. Each group must have a unique owner. (There is a virtual
2837 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2838 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2839 :     and CM would check that such a declaration is correct. The new scheme
2840 :     is to have CM check that for each group there is precisely one owning
2841 :     library.
2842 :    
2843 :     The advantage of the new scheme is that the programmer no longer needs
2844 :     to maintain the somewhat annoying owner information. The downside is
2845 :     that CM cannot enforce the ownership rule across multiple runs of
2846 :     CM.make. Fortunately, enclosing the same group in two different
2847 :     libraries A and B which are not part of the same program does not
2848 :     cause real problems.

2869 :     Arranged for ml-build to clean up after itself a little bit better.

2872 :     gets rid of those at the end, so they don't accumulate under .cm.

2890 :     Tag: blume-20040511-win32sock
2891 :     Description:
2892 :    
2893 :     Added previously missing support for many socket-related functions
2894 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
2895 :     for the voluminous patch!
2896 :    
2897 :     (I have not tested this patch under win32 yet.)
2898 :    
2899 : mblume 1490 Here is David's e-mail:
2900 :    
2901 :     Hi,
2902 :    
2903 :     Attached to this email you find a diff against sml/nj 110.45
2904 :     that will enable socket support under Windows.
2905 :    
2906 :     To apply the patch (using unix or cygwin)
2907 :     1) gunzip runtime.diff.gz
2908 :     2) "cd" into "src/runtime" in the source tree of a fresh
2909 :     110.45 installation.
2910 :     3) patch -p 1 < [your/path/to]runtime.diff
2911 :    
2912 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2913 :     I only ran a few tests for basic socket client functionality
2914 :     (which worked fine). Especially the functions that use ioctl
2915 : mblume 1490 are not tested at all and might not work (see below).
2916 :    
2917 :     I implemented this since we want to move to a newer version of sml/nj
2918 :     but need socket support in order to use it. This is the first time I
2919 :     even had a look at the sml/nj source, so please review my changes
2920 :     before making this part of the distribution! Here are a few issues
2921 : blume 2155 that I think might be better for someone to solve who is more
2922 : mblume 1490 familiar with the sml/nj source (and socket programming):
2923 :    
2924 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2925 :     exception since I could not figure out what the windows equivalent
2926 :     of these functions is
2927 :    
2928 :     - In sockets-osdep.h there are a some #include statements that are
2929 :     only used in a few files that include sockets-osdep.h
2930 :    
2931 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2932 :     does not process its return value since I don't know how to
2933 :     report an error upwards.
2934 :    
2935 :     - It would probably be good to have a call to WSACleanup() when
2936 : blume 2155 the library is unloaded (if there is such a possibility).
2937 : mblume 1490 Otherwise I think Windows will take care of this automatically
2938 :     when the process finishes.
2939 :    
2940 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2941 :     no idea if that is actually the proper replacement on Windows.
2942 :    
2943 :     - All these issues are marked in the code by "FIXME" comments.
2944 :    
2945 : blume 2155 We use sml/nj extensively in our products and are quite happy
2946 :     with it. I hope this contribution will help you.
2947 : mblume 1490
2948 :     Keep up the good work!
2949 :

2989 :     everything. (Notice that this refers to source code only. Compiled
2990 :     code is still only installed for modules that were requested explicitly
2991 :     or which are required for other modules that were requested explicitly.)

3025 :     Description:
3026 :    
3027 :     Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
3028 :     of SML/NJ. The problem is that
3029 :    
3030 :     lib = dlopen(NULL, ...)
3031 :     f = dlsym(lib, "malloc");
3032 :    
3033 : blume 2155 does not work on Windows unless we explicitly export symbols
3034 :     such as 'malloc' during linking. We fixed this by explicitly
3035 : allenleung 1468 exporting the required symbols with the magic gcc incantation:
3036 :    
3037 :     -Wl,--export-all cygwin.def
3038 :    
3039 :     where cygwin.def is a file containing all the symbols that
3040 : blume 2155 we wish to export.
3041 : allenleung 1468
3042 : blume 2155 I suspect this is a Windows problem and we'll have to
3043 :     do the same (somehow with windows compilers) when
3044 : allenleung 1468 we build the native win32 version with the system
3045 : blume 2155 calls LoadLibrary/GetProcAddress.

3116 :     (The mechanism was broken and could not be fixed easily. Moreover,
3117 :     there does not seem to be any reason not to move all libraries into

3121 :     old CM is not an option, there is no reason to keep it around.)

3170 :     Tag: blume-20030926-ppautoload
3171 :     Description:
3172 :    
3173 :     I modified the read-eval-print loop so that the autoloader gets
3174 :     invoked whenever the prettyprinter tries to look up a symbol that
3175 :     is not currently defined in the toplevel environment but which
3176 :     appears in CM's autoload registry. As a result, we see far fewer of
3177 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3178 :    
3179 :     In addition to this I tried to clean up some pieces of the Basis
3180 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3181 :     instances of these ?.Foo.Bar.xxx names from being printed.
3182 :    
3183 :     The mechanism that picks names for types still needs some work, though.
3184 :     (Right now it seems that if there is a type A.t which is defined to
3185 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3186 :     "?.B.u" although the perhaps more sensible solution would be to use
3187 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3188 :     a chain of DEFtycs not farther than there are corresponding toplevel
3189 :     names in the current environment.)

3195 :     Description:
3196 :    
3197 :     Another installer tweak: All the ML code for the installer is now
3198 :     compiled during CMB.make and put into a little library called
3199 :     $smlnj/installer.cm. The installation then simply invokes
3200 :    
3201 :     sml -m $smlnj/installer.cm
3202 :    
3203 :     and everything happens automagically.
3204 :    
3205 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3206 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3207 :     and BINDIR.
3208 :    
3209 :     The new scheme guarantees that the ML code responsible for the installation
3210 :     is in sync with the APIs of the main system. Also, the installer is
3211 :     somewhat faster because the installer script is precompiled.

3228 :     Tag: blume-20030924-sockets
3229 :     Description:
3230 :    
3231 :     1. Fixed SOCKET API and implementation to match Basis spec.
3232 :     This required changing the internal representation of sockets to one
3233 :     that remembers (for each socket file descriptor) whether it is currently
3234 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3235 :     call is made only if the state actually needs to change).
3236 :    
3237 :     2. OS-specific details of sockets were moved into separate files, thus
3238 :     making it possible to unify the bulk of the socket implementations
3239 :     between Unix and Win32.
3240 :    
3241 :     3. CML's socket API changed accordingly.
3242 :     (Note that we need to remove non-blocking functions from this API
3243 :     since they are redundant in the case of CML!)
3244 :    
3245 :     4. CML's socket implementation now makes use of non-blocking functions
3246 :     provided by Basis, thus removing all OS-dependent code from this part
3247 :     of CML.
3248 :    
3249 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3290 :     Description:
3291 :    
3292 :     1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
3293 :     this seems to be controversial at the moment) and used those in
3294 :     Posix.ProcEnv.times.
3295 :    
3296 :     2. Added Time.{from,to}Nanoseconds to Time.
3297 :    
3298 :     3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
3299 :     For example, fromLargeInt never needs to look at more than 3 "big
3300 :     digits" to get its 53 bits of precision.

3306 :     Description:
3307 :    
3308 :     Added an entry to the primitive environment
3309 :     (compiler/Semant/statenv/prim.sml) for int32->real64 conversion and
3310 :     added code to compiler/CodeGen/main/mlriscGen.sml to implement it.
3311 :    
3312 :     Removed some of the "magic" constants in real64.sml and replaced them
3313 :     with code that generates these values from their corresponding
3314 :     integer counterparts.
3315 :    
3316 :     Made all(?) the slice-related changes to the Basis and made everything
3317 :     compile again...

3361 :     Tag: blume-20030909-installer
3362 :     Description:
3363 :    
3364 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3365 :     Modified config/install.bat to take advantage of it. Also modified
3366 :     config/install.sh (and called it config/new-install.sh) to take advantage
3367 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3368 :     independent.)
3369 :    
3370 :     The installer can now install everything under Win32
3371 :     as well as under *nix as long as it compiles.
3372 :    
3373 :     Other changes:
3374 :    
3375 :     - made CML compile again under Win32
3376 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3377 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3378 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3379 :     same as type int; under Win32 it isn't
3380 :     - fixed some slice-related problems in the win32-specific parts of CML
3381 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3382 :     (under Win32, the volume name is case-insensitive, and the
3383 :     OS.Path code compares volume names for equality)

3389 :     Description:
3390 :    
3391 :     Made Win32 version of OS.FileSys.fullPath return current directory
3392 :     when given an empty string. This is what the spec says, and incidentally,
3393 :     CM depends on it. (CM otherwise goes into an infinite loop in certain
3394 :     cases when presented with the name of a non-existing .cm file.)

3399 : mblume 1352 Tag: blume-20030905-slices-etc
3400 : mblume 1350 Description:
3401 :    
3402 :     1. Changed interface to vectors and arrays in Basis to match
3403 :     (draft) Basis spec.
3404 :     2. Added signatures and implementations of slices according to
3405 :     Basis spec.
3406 :     3. Edited source code throughout the system to make it compile again
3407 :     under 1. and 2. (In some cases code had to be added to have it
3408 :     match the new signatures.)
3409 :     4. MLRISC should be backward-compatible: the copies of the originals
3410 :     of files that needed to change under 3. were retained, the .cm files
3411 :     check the compiler version number and use old versions when
3412 :     appropriate.
3413 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3414 :     dirstream -> string option (in accordance with Basis spec).
3415 :     6. When generating code that counts lines, ml-lex used function
3416 :     CharVector.foldli, taking advantage of its old interface.
3417 :     This has been replaced with the corresponding code from
3418 :     CharVectorSlice. (html-lex must be re-lexed!)
3419 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3420 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3421 :     8. Removed temporary additions (fromInternal, toInternal) from the
3422 :     (now obsolete) IntInf in smlnj-lib/Util.
3423 :     9. Cleaned up structure Byte.
3424 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3425 :     Cleaned/corrected implementation of Date.
3426 :     (Still need to check for correctness; implement better canonicalizeDate.)
3427 :     11. Added "scan" to signature IEEE_REAL.
3428 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3429 :     mod and rem when second operand is 2 (for parity checks).]
3430 :     13. Changed representation of type Time.time, using a single IntInf.int
3431 :     value counting microseconds. This considerably simplified the
3432 :     implementation of structure Time. We now support negative time
3433 :     values; scan and fromString handle signs.
3434 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3435 :     ArraySlice).

3440 :     Tag: blume-20030828-intinf
3441 :     Description:
3442 :    
3443 :     This is a major update which comes with a version number bump
3444 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3445 :     and an implementation of IntInf in the Basis.
3446 :    
3447 :     There are a fairly large number of related changes and updates throughout
3448 :     the system:
3449 :    
3450 :     Basis:
3451 :     - Implemented IntInf.
3452 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3453 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3454 : mblume 1347 - Added FixedInt as a synonym for Int32.
3455 :    
3456 :     compiler:
3457 :     * Added support for a built-in intinf type.
3458 :     - literals
3459 :     - pattern matching
3460 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3461 :     - overloading on literals and operations
3462 :    
3463 :     This required adding a primitive type intinf, some additional
3464 :     primops, and implementations for several non-trivial intinf
3465 :     operations in Core. (The intinf type is completely abstract
3466 :     to the compiler; all operations get delegated back to the Core.)
3467 :    
3468 :     * Intinf equality is handled by polyequal. However, the compiler
3469 :     does not print its usual warning in this case (since polyequal
3470 :     is the right thing to do there).
3471 :    
3472 :     * Improved the organization of structure InlineT.
3473 :    
3474 :     * A word about conversion primops:
3475 :     If conversions involving intinf do not cancel out during
3476 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3477 : mblume 1347 Since all core access must be resolved already during the FLINT
3478 :     translate phase, it would be too late a the time of CPS contract
3479 : mblume 1348 to add new Core calls. For this reason, conversion primops
3480 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3481 :     they are supposed to convert, and 2. the Core function that
3482 :     can help with this conversion if necessary. If CPS contract
3483 : mblume 1348 eliminates a primop, then the associated Core function becomes
3484 :     dead and goes away. Intinf conversion primops that do not get
3485 :     eliminated by CPS contract get rewritten into calls of their
3486 :     core functions by a separate, new phase.
3487 : mblume 1347
3488 :     interactive system:
3489 :     - Control.Print.intinfDepth controls max length of intinf constants
3490 :     being printed. (Analogous to Control.Print.stringDepth.)
3491 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3492 :     duplicates; replaced some of the code with code that makes better
3493 :     use of library functionality.
3494 :    
3495 :     CM:
3496 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3497 :     are no longer silent.
3498 :    
3499 :     CKIT:
3500 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3501 :     in favor of LargeInt -- which is now the same as IntInf.
3502 :     CKIT-knowledgable people should check whether this is what's
3503 :     intended and otherwise change things back to using Int32 or
3504 :     FixedInt.
3505 :    
3506 :     Throughout the code:
3507 : mblume 1348 Started using IntInf.int literals and built-in operations
3508 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3527 :     Tag: blume-20030811-windows
3528 :     Description:
3529 :    
3530 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3531 :    
3532 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3533 :    
3534 :     This patch restores SML/NJ's ability to run under win32. There are a
3535 :     number of changes, including fixes for several bugs that had gone
3536 :     unnoticed until now:
3537 :    
3538 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3539 :     trying to run the win32 version from within cygwin.)
3540 :    
3541 :     - There are a number of simple .bat scripts that substitute for their
3542 :     corresponding Unix shell-scripts. (See below.)
3543 :    
3544 :     - The internals of ml-build have been modified slightly. The main
3545 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3546 :     using OS.Process.system, the ML process delegates this task back
3547 :     to the script. Otherwise problems arise in mixed environments such
3548 :     as Cygwin where scripts look and work like Unix scripts, but
3549 :     where OS.Process.system cannot run them.
3550 :    
3551 :     - In CM, the srcpath pickler used native pathname syntax -- which
3552 :     is incorrect in the case of cross-compilation. The new pickle format
3553 :     is independent of platform-specific naming conventions.
3554 :    
3555 :     - Path configuration files (such as lib/pathconfig) can now choose
3556 :     between native and standard syntax. Placing a line of the form
3557 :    
3558 :     standard!
3559 :    
3560 :     into the file causes all subsequent paths to be interpreted using
3561 :     CM standard pathname syntax (= Unix conventions); a line
3562 :    
3563 :     native!
3564 :    
3565 :     switches back to native style. This was needed so that
3566 :     path config files can be written portably, see src/system/pathconfig.
3567 :    
3568 :     - Runtime system:
3569 :    
3570 :     - win32-filesys.c: get_file_time and set_file_time now
3571 :     access modification time, not creation time.
3572 :    
3573 :     - I/O code made aware of new array representation.
3574 :    
3575 :     - Bug fixes in X86.prim.masm.
3576 :    
3577 :     - src/system/makeml made aware of win32. (For use under cygwin
3578 :     and other Unix-environments for windows.)
3579 :    
3580 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3581 :     which caused BinIO.inputAll to fail consistently.
3582 :    
3583 :     .bat scripts:
3584 :    
3585 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3586 :    
3587 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3588 :     applications (sml, ml-yacc, ml-lex).
3589 :     - ml-build.bat: analogous to ml-build.
3590 :     - config\install.bat: Analogous to config/install.sh. This requires
3591 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3592 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3593 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3594 :     and the bootfile hierarchy must have been unpacked under
3595 :     sml.boot.x86-win32.
3596 :     The script is very primitive and does a poor job at error checking.
3597 :     It only installs the base system, ml-lex, and ml-yacc. No other
3598 :     libraries are being installed (i.e., you get only those that
3599 :     are part of the compiler.)
3600 :     - link-sml.bat: analogous to .link-sml, but not currently used
3601 :    
3602 :     Unrelated bug fixes:
3603 :    
3604 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3605 :     types.
3606 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3607 :     otherwise.)

3631 :     Description:
3632 :    
3633 :     Two changes:
3634 :    
3635 :     1. Added a flag for controlling whether non-exhaustive bindings will
3636 :     be treated as errors (default is false).
3637 :     2. Cleaned up the *entire* source tree so that CMB.make goes through

3644 :     Description:
3645 :    
3646 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3647 :    
3648 :     This mainly affects the quality of error messages. However, some
3649 :     of the code is now more straightforward than before. (Treatment of
3650 :     the above four constructs in translate.sml is much simpler than
3651 :     the "macro-expansion" that was going on before. Plus, the mach-
3652 :     compiler no longer gets invoked just to be able to compile an
3653 :     if-expression.)
3654 :    
3655 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3656 :     interactive loop.

3704 :     Fixed a serious bug in the rewrite code for FP spilling/reloading that
3705 :     sent the RA into an infinite loop when floating point registers get
3706 :     spilled. (Because of this bug, e.g., nucleic stopped compiling between
3707 :     110.37 and 110.38.)
3708 :     There was another set of potential problems related to the handling of
3709 :     MLRISC annotations (but those did not yet cause real problems, apparently).

3718 :     This fixes the problem of CM getting confused by files that suddenly
3719 :     change their identity (e.g., by getting unlinked and recreated by some

3737 : blume 1282 In good old tradition, there has been a slight hiccup so that we have

3743 :     each other's way.
3744 :

3832 :    
3833 :     Another small change is that ppDec tries to give more information
3834 :     than just "<sig>" in the case of functors. However, this code is
3835 :     broken in some mysterious way if the functor's body's signature
3836 :     has not been declared by ascription but gets inferred from the
3837 :     implementation. This needs fixing...

3906 :    
3907 :     * Removed again all the stuff from config/preloads that one wouldn't
3908 :     be able to preload at the time the initial heap image is built.

3937 :    
3938 :     0. John Reppy made several modifications to the SML/NJ library.
3939 :     In particular, there is a shiny new controls-lib.cm.
3940 :    
3941 :     1. Pushed new controls interface through compiler so that everything
3942 :     compiles again.
3943 :    
3944 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3945 :     SML/NJ library (so that CML compiles again).
3946 :    
3947 :     3. Modified init scripts because XXX_DEFAULT environment variables
3948 :     are no longer with us. (Boot-time initialization is now done
3949 :     using the same environment variables that are also used for
3950 :     startup-time initialization of controls.)

3956 :     Description:
3957 :    
3958 :     All pseudo-ops emitted before the first segment declaration
3959 :     such as TEXT, DATA, and BSS directives are assumed to be global
3960 :     declarations and are emitted first in the assembly file. This is
3961 :     useful in a number of situations where one has pseudo-ops that are not
3962 :     specific to any segment, and also works around the constraint that one
3963 :     cannot have client pseudo-ops in the TEXT segment.
3964 :    
3965 :     Because no segment is associated with these declarations it is
3966 :     an error to allocate any space or objects before the first segment
3967 :     directive and an exception will be raised. However, we cannot make
3968 :     this check for client pseudo-ops.
3969 :    
3970 :     These top level declarations are a field in the CFG graph_info.
3971 :     In theory you can continue to add to this field after the CFG has been
3972 :     built -- provided you know what you are doing;-)

3995 :     Description:
3996 :    
3997 :     Applied the following bugfix provided by Emden Gansner:
3998 :    
3999 :     Output is corrupted when outputSubstr is used rather than output.
4000 :    
4001 : blume 2155 The problem occurs when a substring
4002 : blume 1189
4003 :     ss = (s, dataStart, dataLen)
4004 :    
4005 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
4006 :     avail bytes of s, starting at index dataStart, are copied into the
4007 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
4008 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
4009 :     starting this copy at index dataStart+avail in s, the current code
4010 : blume 1189 starts the copy at index avail.
4011 :    
4012 :     Fix:
4013 :     In text-io-fn.sml, change line 695 from
4014 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
4015 : blume 2155 to

4032 :     Description:
4033 :    
4034 :     Added full support for div/mod/rem/quot on the x86, using the machine
4035 :     instruction's two results (without clumsily recomputing the remainder)
4036 :     directly where appropriate.
4037 :    
4038 :     Some more extensive power-of-two support was added to the x86 instruction
4039 :     selector (avoiding expensive divs, mods, and muls where they can be
4040 :     replaced with cheaper shifts and masks). However, this sort of thing
4041 :     ought to be done earlier, e.g., within the CPS optimizer so that
4042 :     all architectures benefit from it.
4043 :    
4044 :     The compiler compiles to a fixed point, but changes might be somewhat
4045 :     fragile nevertheless. Please, report any strange things that you might
4046 :     see wrt. div/mod/quot/rem...

4054 :     Fixed my broken div/mod logic. Unfortunately, this means that the

4056 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
4057 :     The problem was with quotient = 0, because that alone does not tell
4058 :     us which way the rounding went. One then has to look at whether
4059 :     remainder and divisor have the same sign... :(

4078 :

4082 :    
4083 :     * handled these primops all the way through so they map to their respective
4084 :     MLRISC support
4085 :    
4086 :     * used these primops in the implementation of Int, Int32, Word, Word32
4087 :    
4088 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
4089 :    
4090 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
4091 :    
4092 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
4093 :     floating point
4094 :    
4095 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
4096 :     and Real (but Real.abs maps to a separate floating-point-only primop)

4099 :     TODO items:
4100 :    
4101 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
4102 :     instructions because the machine instruction encoder cannot handle
4103 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
4104 :     REM in the first place, and REM is supported by the x86 machine coder.)
4105 :    
4106 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
4107 :     selection phase. (The two can be streamlined because the hardware
4108 :     delivers both quotient and remainder at the same time anyway.)
4109 :    
4110 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
4111 :     (Currently the behavior is inconsistent both across architectures and
4112 :     wrt. the draft Basis spec.)
4113 :    
4114 :     * Word8 should eventually be handled natively, too.
4115 :    
4116 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
4117 :     as if there currently is no execution path that could trigger it in
4118 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
4119 :     hold for things like multiplication and division.)

4124 :     Tag: blume-20020327-mlrisc-divisions
4125 :     Description:
4126 :    
4127 :     Added support for all four division operations (ML's div, mod, quot,
4128 :     and rem) to MLRISC. In the course of doing so, I also rationalized
4129 :     the naming (no more annoying switch-around of DIV and QUOT), by
4130 :     parameterizing the operation by div_rounding_mode (which can be either
4131 :     DIV_TO_ZERO or DIV_TO_NEGINF).
4132 :    
4133 :     The generic MLTreeGen functor takes care of compiling all four
4134 :     operations down to only round-to-zero div.
4135 :    
4136 :     Missing pieces:
4137 :    
4138 :     * Doing something smarter than relying on MLTreeGen on architectures
4139 :     like, e.g., the x86 where hardware division delivers both quotient and
4140 :     remainder at the same time. With this, the implementation of the
4141 :     round-to-neginf operations could be further streamlined.
4142 :    
4143 :     * Remove inlining support for div/mod/rem from the frontend and replace it
4144 :     with primops that get carried through to the backend. Do this for all
4145 :     int and word types.

4151 :     Description:
4152 :    
4153 :     I improved (hopefully without breaking them) the implementation of Int.div,
4154 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
4155 :     advantage of the following observations:
4156 :    
4157 :     Let q = x quot y r = x rem y
4158 :     d = x div y m = x mod y
4159 :    
4160 :     where "quot" is the round-to-zero version of integer division that
4161 :     hardware usually provides. Then we have:
4162 :    
4163 :     r = x - q * y where neither the * nor the - will overflow
4164 :     d = if q >= 0 orelse x = q * y then q else q - 1
4165 :     where neither the * nor the - will overflow
4166 :     m = if q >= 0 orelse r = 0 then r else r + y
4167 :     where the + will not overflow
4168 :    
4169 :     This results in substantial simplification of the generated code.
4170 :     The following table shows the number of CFG nodes and edges generated
4171 :     for
4172 :     fun f (x, y) = x OPER y
4173 :     (* with OPER \in div, mod, quot, rem *)
4174 :    
4175 :    
4176 :     OPER | nodes(old) | edges(old) | nodes(new) | edges(new)
4177 :     --------------------------------------------------------
4178 :     div | 24 | 39 | 12 | 16
4179 :     mod | 41 | 71 | 12 | 16
4180 :     quot | 8 | 10 | 8 | 10
4181 :     rem | 10 | 14 | 8 | 10
