406 :     Revision: 2650
407 :     Description:
408 :    
409 :     3rd merge of base from primop-branch-3 into the trunk.
410 :     Additional bug fixes included:
411 :    
412 :     * Timer.cpu_timer, etc. type printing corrected (by making
413 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
414 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
415 :     Stefan Monnier)

419 :     Date: 2007/05/31 11:40:00 CDT
420 :     Description:
421 :    
422 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
423 :    
424 :     Also, changed the handling of "no core access": When translate.sml
425 :     needs access to a core exception at a time when the core has not
426 :     been set up yet (this only happens when compiling system/smlnj/init/*),
427 :     then don't bother generating the corresponding tests.
428 :    
429 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
430 :     the exception. Unfortunately, that confuses the plambda type checker.
431 :     Moreover, it does not do any good, because at runtime we don't expect
432 :     such an exception to be ever raised. (The code in system/smlnj/init/*
433 :     has to be written very carefully with this in mind!)

445 :     Description:
446 :    
447 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
448 :     with an explicit test for zero division. This should fixes several
449 :     regressions and makes it possible for downstream optimization phases
450 :     to treat these operations as "pure" when they are applied to unsigned
451 :     operands.

456 :     Description:
457 :    
458 :     Added the new MLRISC code generator for the AMD64. This version,
459 :     in contrast to the previous one, uses SSE registers and instructions
460 :     for all floating-point computations.

465 : jhr 2613 Description:
466 :    
467 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
468 :     for bugs #1415 and #1416. We also now correctly handle format characters that
469 :     lie outside the specified set.

473 :     Date: 2007/05/23 22:30:00 CDT
474 :     Description:
475 :    
476 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
477 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
478 :    
479 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
480 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
481 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
482 :     while running CMB.make. The point is that the single symbol
483 :     NO_PLUGINS is definde in all three cases.)
484 :    
485 :     I changed the three locations within the sources that get compiled
486 :     during CMB.make where ml-yacc or ml-lex input is processed: When
487 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
488 :     is bypassed.
489 :    
490 :     When bootstrapping new versions of the compiler, there can be
491 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
492 :     are not available or otherwise not operational. In this case one can
493 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
494 :     do so, the following command should be issued at the interactive
495 :     prompt:
496 :    
497 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
498 :    
499 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
500 :     files that normally would be generated by ml-yacc and ml-lex.
501 :     (Copies of these files are in the repository.)

508 :    
509 :     2nd merge of base from primop-branch-3 into the trunk.

517 :     Description:
518 :    
519 :     Changed the installation mechanism for CM tool plugins. These are
520 :     just libaries and now get installed like ordinary libaries.
521 :    
522 :     There are now a number of new installation targets that give some
523 :     fine-grain control over what classes and suffixes are known, and what
524 :     they will map to.
525 :     See config/targets for details.
526 :    
527 :     The code that caused plugin installation as part of running a
528 :     tool's "build" script has been removed. (The build script is for
529 :     building, not for installing.)

534 :     Description:
535 :    
536 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
537 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
538 :     CM fail if a shell tool reports a non-success exit status. If
539 :     the control is set to true, then CM will press on after tool failures
540 :     in the event that the target files exist (even though they are
541 :     considered outdated). Turning the control to true can be useful for
542 :     bootstrapping.

547 :     Description:
548 :    
549 :     Merge of ml-lpt revisions for 110.64.
550 :    
551 :     The name of several ml-lpt-lib modules has changed:
552 :     Repair => AntlrRepair
553 :     StreamPos => AntlrStreamPos
554 :     ErrHandlerFn => AntlrErrHandler
555 :     EBNF => AntlrEBNF
556 :    
557 :     The ml-antlr specification format has changed: declarations such as
558 :     %tokens and nonterminal definitions can occur *multiple* times in the
559 :     same specification. The semantics are such that each new declaration
560 :     extends the previous ones. This does not apply to %start or %name,
561 :     of course.
562 :    
563 :     Importing a grammar via %import now includes *all* declarations in from
564 :     the imported grammar, except for %name, %entry, and %start. Tokens
565 :     and nonterminals can be dropped using the new %dropping clause of the
566 :     %import directive; the separate %drop and %extend have been removed.
567 :    
568 :     We now allow optional type annotations on nonterminals, using the %nonterms
569 :     directive as in ml-yacc.
570 :    
571 :     The refcell construct is now implemented using SML's regular reference
572 :     cells, so the :== and !! notation has been deprecated.
573 :    
574 :     The ml-antlr tool now does much more checking of specifications, and
575 :     its error messages have been greatly improved. Error repair for
576 :     generated parsers has been completely rewritten, and is now both
577 :     much faster and more accurate.
578 :    
579 :     ml-ulex is now more lenient with escape codes (non-SML-standard
580 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
581 :     Also, character classes may now include a "-" character at the beginning
582 :     as is standard in most other regexp tools.
583 :    
584 :     All of these changes are documented in the user guide, which has
585 :     been updated and improved with this merge.

736 :     Description:
737 :    
738 :     Added preliminary support in MLRISC for Staged Allocation, a technique
739 :     for specifying calling conventions (see
740 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
741 :     Initially, we plan to use this code to generate C calls for the AMD64.
742 :    
743 :     The staged allocation code base resides in MLRISC/staged-allocation,
744 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

808 :     Date: 2007/01/31
809 :     Description:
810 :    
811 :     Brought ml-lpt manual up-to-date with the code. Many minor
812 :     improvements to the tools, and a few minor bugfixes. Prepared
813 :     ml-lpt-lib for integration with new UTF8 structure. Changed
814 :     the interface for creating streams in ml-ulex (we now support
815 :     stream creation from several kinds of sources). Overall, the
816 :     tools are now quite stable, and their interfaces are unlikely to
817 :     change in a way that would break compatibility. More work,
818 :     however, is needed in the documentation.

823 :     Description:
824 :    
825 :     Implemented library installer. Moved CM plugin code for
826 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
827 :     their respective trees. Implemented CM plugin for ml-ulex
828 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
829 :     and ml-antlr.
830 :    
831 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
832 :     CM tools. (It turns out to be too messy to do otherwise because
833 :     there is too much code that during installation relies on the presence
834 :     of these tools -- resulting in a tricky ordering problem.)

839 :     Description:
840 :    
841 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
842 :     Modified CM's startup code to use shiftArgs as it processes
843 :     command line arguments. This way, the init code in each .sml-file
844 :     or library that is mentioned at the top level will see only
845 :     those arguments that have not yet been processed at this point.
846 :     In other words, the init code can "seize control" and process the
847 :     remaining command line.

903 :     Description:
904 :    
905 :     Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to
906 :     get the c_cc termios data copied correctly. Also moved the allocation

913 :     Date: 2006/12/08 09:50:00 CST
914 :     Description:
915 :    
916 :     Added code to CM's "standard shell tool" implementation which
917 :     causes it to tolerate (with a warning) the situation where the shell
918 :     command fails (e.g., due to the shell command's non-existence)
919 :     as long as all target files exist.
920 :    
921 :     This makes it possible to, e.g., build ml-yacc from sources even if
922 :     svn checkout messed up the time stamps on files in such a way that
923 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
924 :     be needed to re-process yacc.grm, but obviously it might not yet be
925 :     available at that time.)

931 :    
932 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
933 :     recvVecFromNB' in the SOCKET signature. This error is actually
934 :     in the SML Basis specification too.

964 :     Tag: release-110.60
965 :     Description:
966 :    
967 :     New working release (110.60). NEW BOOTFILES!
968 :    
969 :     This is the first subversion-hosted release. There are also changes
970 :     to the directory layout. Here is a table:
971 :    
972 :     (All pathnames are relative to the SML/NJ "root" directory.)
973 :    
974 :     config -> config
975 :    
976 :     src/cm -> base/cm
977 :     src/compiler -> base/compiler
978 :     src/runtime -> base/runtime
979 :     src/system -> base/system
980 :    
981 :     src/cm/pgraph -> pgraph
982 :    
983 :     src/READMES -> base/READMES
984 :     src/$notefile -> base/NOTES/$notefile
985 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
986 :     MACOSXINSTALL WININSTALL
987 :    
988 :     src/smlnj-lib -> smlnj-lib
989 :     src/MLRISC -> MLRISC
990 :     ckit -> ckit
991 :     src/cml -> cml
992 :     src/eXene -> eXene
993 :     src/heap2asm -> heap2asm
994 :     src/lexgen -> lexgen
995 :     src/ml-burg -> ml-burg
996 :     src/ml-lex -> ml-lex
997 :     src/ml-yacc -> ml-yacc
998 :     src/ml-nlffi-lib -> nlffi/lib
999 :     src/ml-nlffigen -> nlffi/gen
1000 :     src/smlnj-c -> smlnj-c
1001 :     src/tools/TraceDebugProf -> trace-debug-profile
1002 :    
1003 :     In addition, there is also a new
1004 :    
1005 :     ml-lpt
1006 :    
1007 :     directory containing two new program generator tools: ml-ulex and
1008 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1009 :     LL(k) parser generator). These tools are currently "beta-quality"
1010 :    
1011 :     The latest versios of the sources can now be obtained anonymously
1012 :     via subversion. For this, it is useful to first check out
1013 :    
1014 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1015 :    
1016 :     and put the resulting directory on your shell's PATH. This provides
1017 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
1018 :     and refresh-all.sh.
1019 :    
1020 :     To create a freshly checked-out copy of the sources, do
1021 :    
1022 :     checkout-all.sh [dir]
1023 :    
1024 :     where dir is the optional SML/NJ root directory (default is ".").
1025 :    
1026 :     This creates the above directory layout. Each subdirectory of
1027 :     the root is under individual subversion control. The stat-all.sh
1028 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
1029 :     each of these subtrees.
1030 :    
1031 :     ----------------------------------------------------------------------
1032 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
1033 : blume 2155 Date: 2006/11/02 12:20:00 CST
1034 :     Description:
1035 :    
1036 :     Reorganized directory layout.
1037 :    
1038 :     This is a temporary solution, more reorganization is to come.
1039 :    
1040 :     The basic idea is to have a number of toplevel trees, each corresponding
1041 :     to a well-defined part of the overall system. Each part can be
1042 :     maintained individually, even in separate source repositories,
1043 :     although currently we still serve everything out of the main
1044 :     smlnj-gforge tree.
1045 :    
1046 :     Installer and and scripts have been updated to reflect the new
1047 :     layout. The installer (base/src/system/smlnj/installer) is now
1048 :     "scriptable" to avoid burning too much knowledge about the
1049 :     layout into SML source code. The main script used by the installer
1050 :     is in config/actions.
1051 :    
1052 :     The main change is that many of the subdirectories of what used to
1053 :     be known as "src" have moved to the toplevel. The "src" directory
1054 :     itself has moved down into a subtree called "base". (We may eventually
1055 :     get rid of the extra level of indirection represented by "src".)
1056 :    
1057 :     The layout is now as follows:
1058 :    
1059 :     toplevel tree name | default repository
1060 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1061 :     -------------------+----------------------------------------------------
1062 :     config | $gf/config/trunk
1063 :     |
1064 :     base | $gf/sml/trunk
1065 :     |
1066 :     smlnj-lib | $gf/smlnj-lib/trunk
1067 :     MLRISC | $gf/MLRISC/trunk
1068 :     |
1069 :     ml-yacc | $gf/ml-yacc/trunk
1070 :     ml-lex | $gf/ml-lex/trunk
1071 :     ml-burg | $gf/ml-burg/trunk
1072 :     lexgen | $gf/lexgen/trunk
1073 :     heap2asm | $gf/heap2asm/trunk
1074 :     |
1075 :     cml | $gf/cml/trunk
1076 :     eXene | $gf/eXene/trunk
1077 :     ckit | $gf/ckit/trunk
1078 :     nlffi | $gf/nlffi/trunk
1079 :     |
1080 :     smlnj-c | $gf/smlnj-c/trunk
1081 :    
1082 :     In $gf/admin there are a few useful shell scripts for checking out
1083 :     and maintaining the entire collection of trees:
1084 :    
1085 :     admin/checkout-all.sh [dir]
1086 :     -- optionally creates dir and checks out all trees from their
1087 :     default repositories; if dir is missing, checkout into .
1088 :     admin/refresh-all.sh [dir]
1089 :     -- looks at all trees (from the above list) in dir (default: .)
1090 :     and runs "svn update" if the tree exists and is under
1091 :     subversion control;
1092 :     non-existing or non-subversion trees are skipped
1093 :     admin/stat-all.sh [dir]
1094 :     -- like refresh-all.sh, but runs "svn stat" instead

1297 :     Description:
1298 :    
1299 :     Fixed a problem in config/install.sh where it tries to "fish" the
1300 :     name of the CM metadata directory from the wrong place (because
1301 :     the physical location of basis.cm has changed). Also, corrected the
1302 :     path anchor for $/html-lib.cm. (Thanks to M. Fluet for pointing out
1303 :     these problems.)

1336 :     Tag: blume-22051115-versiontool
1337 :     Description:
1338 :    
1339 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1340 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1341 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1342 :     it. Instead, it has the status of "user code", so it should use
1343 :     $/basis.cm to refer to the Basis library. (At least that's true for
1344 :     the purpose of bootstrapping the previous change. In the future it
1345 :     might make sense to have versiontool.cm refer to
1346 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1347 :     compiler itself uses.)
1348 :    
1349 :     Also patched src/system/testml to have it activate those extra anchor
1350 :     bindings in config/extrapathconfig.

1355 :     Tag: blume-22051115-libraries
1356 :     Description:
1357 :    
1358 :     This change affects the way the following libraries are tied into
1359 :     the system:
1360 :    
1361 :     $/basis.cm
1362 :     $/smlnj-lib.cm
1363 :     $/pp-lib.cm
1364 :     $/controls-lib.cm
1365 :     $/html-lib.cm
1366 :     $/ml-yacc-lib.cm
1367 :    
1368 :     These libraries are now internally (as seen from the source code
1369 :     of the implementation itself) known by the following names:
1370 :    
1371 :     $smlnj/basis/basis.cm
1372 :     $smlnj/smlnj-lib/smlnj-lib.cm
1373 :     $smlnj/smlnj-lib/pp-lib.cm
1374 :     $smlnj/smlnj-lib/controls-lib.cm
1375 :     $smlnj/smlnj-lib/html-lib.cm
1376 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1377 :    
1378 :     This makes it possible to work with code that requires different
1379 :     versions of these libraries, and which refers to these libraries using
1380 :     their "default" names (i.e., the first set of names above). In other
1381 :     words, one can un-define or re-define those default names without
1382 :     compromising the proper functioning of the compiler itself.
1383 :    
1384 :     A similar procedure had already been performed for several of the
1385 :     MLRISC libraries that are linked into the compiler. I did some
1386 :     cleanup on this code.
1387 :    
1388 :     A new file in the config directory (named extrapathconfig) is
1389 :     responsible for setting up path anchors that the compiler itself does
1390 :     not need, but that are typically required by user code.

1570 :     Description:
1571 :    
1572 :     Added mechanism for re-creating a heap file for the interactive system
1573 :     after configuration variables have been changed.
1574 :    
1575 :     CM.redump_heap : string -> unit
1576 :    
1577 :     This is much like SMLofNJ.exportML, but starting from the resulting
1578 : blume 2155 heap does not return to the caller of CM.redump_heap but
1579 : mblume 1792 restarts the interactive system from scratch. The original call of
1580 :     CM.redump_heap does not return but ends the interactive session.
1581 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1582 :    
1583 :     Internally, redump_heap winds the dynamic execution context back to
1584 :     the point where the original heap image was created and re-executes
1585 :     the heap image generation code in the boot code.

1684 :    
1685 :     Minor cleanup in ML-Yacc rule printing mechanism. This should fix a
1686 :     problem with certain "as" patterns which previously got rendered
1687 :     using incorrect syntax.

1701 :     Tag: blume-20050114-heap2exec
1702 :     Description:
1703 :    
1704 :     Implemented new (but still experimental) heap2exec facility. This is
1705 :     tested under Mac OS X and should work under Linux (will test shortly).
1706 :     It will probably also work on the Sparc (will test some time later).
1707 :    
1708 :     - removed old "HACKED_STANDALONE" hack from runtime
1709 :    
1710 :     To be able to test this, uncomment the request for "heap2asm" in
1711 :     config/targets prior to installation. (Notice that this is different
1712 :     from "heap2exec" mentioned below. Not a typo.)
1713 :    
1714 :     To perform an actual test, run the command
1715 :    
1716 :     $ bin/heap2exec heapfile execfile
1717 :    
1718 :     (You can put heap2exec on your shell's path.)
1719 :    
1720 :     For example, run
1721 :    
1722 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1723 :    
1724 :     This will create a standalone executable called "mly" which you can
1725 :     then invoke directly as a command.

1751 :     data structure access seems to work.)
1752 :    
1753 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1754 :     (On the Mac, it is big-endian. And that's currently our only
1755 :     PPC platform.)

1870 :     Tag: blume-20041124-position
1871 :     Description:
1872 :    
1873 :     The compiler can now be compiled in a mode that makes structure Position
1874 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1875 :     for the time being.
1876 :    
1877 :     To enable 64-bit positions, use the following procedure:
1878 :    
1879 :     1. Start sml
1880 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1881 :     3. Type
1882 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1883 :     4. Run CMB.make() as usual.
1884 :    
1885 :     This is barely tested. The only test so far was a little SML program
1886 :     counting the number of characters in an 8-gigabyte file by
1887 :     reading it character-by-character. That test was successful.
1888 :    
1889 :     In support of 64-bit positions, a number of new functions have been
1890 :     added to the runtime system.

1935 :    
1936 :     - In a previous commit, fixed a minor issue with how polyequal is being
1937 :     translated. In particular, the code now "looks through" abstractions.
1938 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1939 :     more efficient code. Important examples for where this matters are
1940 :     the new int64 and word64 types.

1959 :     but for the time being they don't even make sense because LargeWord is
1960 :     32-bit wide.)
1961 :    
1962 :     Also started to add similar support for Int64, but major pieces of that
1963 :     are still missing.

1969 :     Description:
1970 :    
1971 :     Structure Word64 is now (almost) complete, word literals and patterns
1972 :     seem to work. There are a few odd pieces missing. In particular,
1973 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1974 :     at the moment.
1975 :    
1976 :     Making Word64 official would mean that LargeWord becomes Word64. But
1977 :     this requires extreme care because most word-word conversions have to
1978 :     go through LargeWord, so making a mistake means loss of efficiency or
1979 :     worse. Eventually there will be a solution similar to (but actually
1980 :     simpler than) what I did with IntInf.

2017 :     normally does not have to be edited to reflect a version change.
2018 :

2060 :     Tag: blume-20041020-standalone-backtrace
2061 :     Description:
2062 :    
2063 :     Added a mechanism for getting back-trace information from standalone
2064 :     programs. Here is how it works:
2065 :    
2066 :     1. The part of the program from which you want to get backtrace
2067 :     information (usually the whole program) should be wrapped with
2068 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
2069 :     main program could be modified from something like
2070 :    
2071 :     fun main (pgm, args) = ...
2072 :    
2073 :     to
2074 :    
2075 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2076 :    
2077 :     2. To be able to access BackTrace.monitor, you have to add
2078 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
2079 :     main function.
2080 :    
2081 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2082 :     CM might have created in the past for your project).
2083 :    
2084 :     4. Build the system using this command line:

2118 :     Description:
2119 :    
2120 :     * Test coverage tool added!
2121 :     * Further reorganization of tracing-, debugging-, and profiling support:
2122 :    
2123 :     - moved original BTImp -- now called BackTrace -- into a separate
2124 :     library called $/trace-debug-profile.cm
2125 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2126 :     - only the instrumentation mechanism is now left in the compiler proper
2127 :     - BackTrace module is a plugin which is NOT plugged in by default
2128 :     - Coverage module is another such plugin
2129 :    
2130 :     To get the benefits of any of these plugin modules, the code in
2131 :     question must be compiled with tdp instrumentation turned on. This
2132 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2133 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2134 :    
2135 :     Plugins are selected at link time. (Pre-compiled instrumented code
2136 :     can be re-loaded with different plugins in effect.) When an
2137 :     instrumented module is linked, whatever plugins are at that time
2138 :     enabled will come into effect for that module.
2139 :    
2140 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2141 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2142 :     To enable the coverage plugin, load the same library and invoke
2143 :     Coverage.install().
2144 :    
2145 :     Back-traces are generated automatically on uncaught exceptions and
2146 :     when the code in question explicitly invokes BackTrace.trigger().
2147 :    
2148 :     Coverage (and execution frequency-) information must be queried
2149 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2172 :     instrumentation for other purposes. "TDP" stands for
2173 :     Trace/Debug/Profile.
2174 :    
2175 :     The control flag controlling whether instrumentation is on or off is now

2177 :    
2178 :     sml -Cinstrument.btrace-mode=true

2198 :     Description:
2199 :

2201 :     treats subsequent occurrences of "group", "library", "source", "is",
2202 :     "*", and "-" as ordinary identifiers rather than keywords.
2203 :    
2204 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool
2205 :     is supposed to accept a tool argument called "source", but this did
2206 :     not work because of the clash with the keyword.

2250 :    
2251 :     * Moved the "version" magic into its own little library under

2257 : mblume 1639
2258 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2259 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2260 :     Also, loading the versiontool does not work when rebuilding the system
2261 :     because CM is not properly initialized at that time.

2266 :     Tag: blume-20040929-autoversion
2267 :     Description:
2268 :    
2269 :     Implemented some CM magic to have
2270 :     file src/compiler/TopLevel/main/version.sml
2271 :     generated automagically.
2272 :     The version is taken from two files: config/version and config/release.
2273 :     The first is expected to contain a two-part version number such as 110.49.
2274 :     The second should contain a single number, but it may be missing.
2275 :    
2276 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2277 :     time the version tool is loaded (which is the first time you say CMB.make),
2278 :     then the tool will increment the value stored in config/release every
2279 :     time CMB.make is invoked.
2280 :    
2281 :     The binfile format is now insensitive to anything beyond the first
2282 :     two components of a version number, so bumping the release does not render
2283 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2284 :     during development without invalidating existing binfiles.
2285 :    
2286 :     In any case, every CMB.make updates the date information in version.sml.
2287 :     (This is the date that is printed in the banner.)

2300 :     Tag: blume-20040927-controls
2301 :     Description:
2302 :    
2303 :     Added two pieces of functionality to the Controls interface:
2304 :    
2305 :     1. val save'restore: 'a control -> unit -> unit
2306 :    
2307 :     grabs the current value of the control in stage 1 and restores it
2308 :     in stage 2.
2309 :    
2310 :     2. val set' : 'a control * 'a -> unit -> unit
2311 :    
2312 :     stores the given value into the control in stage 2 (i.e., delayed)
2313 :     but does all error checking in stage 1.
2314 :     (This is for string controls that need to do parse their argument --
2315 :     something that might fail. In some cases, notably in CM, one
2316 :     already knows the intended argument but wants to delay the actual
2317 :     assignment until a time when error recovery would be more difficult.)
2318 :    
2319 :     Changed the handling of controls in tool arguments to classes "sml" and
2320 :     "lazysml":
2321 :     - use Controls.save'restore as a more robust way of restoring the
2322 :     old value (in particular: without having to re-parse the string)
2323 :     - use controls to handle the "overload" keyword in the init group
2324 :     (I believe this change actually fixes a long-standing obscure bug.)

2329 :     Tag: blume-20040927-lazysml
2330 :     Description:
2331 :    
2332 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2333 :     difference to "sml" is that compilation is done with Control.lazysml
2334 :     set to true. A source of class "lazysml" is automatically recognized
2335 :     by a file name suffix of ".lml".
2336 :    
2337 :     In addition to the above feature, the original class "sml" now also
2338 :     supports a tool argument "lazy" which has the same effect. As a
2339 :     result, the following three lines are equivalent:
2340 :    
2341 :     foo.sml : lazysml
2342 :     foo.sml : sml (lazy)
2343 :     foo.sml (lazy)
2344 :    
2345 :     The setting goes into effect both during parsing and during
2346 :     compilation. The original setting is restored right after parsing and
2347 :     after compilation, respectively.
2348 :    
2349 :     In addition to all the above, there is also a general mechanism to set
2350 :     ANY of the "controls" that are available at the command line via
2351 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2352 :     apply as well. (In fact, "lazy" is implemented as a special case of
2353 :     the general mechanism.)
2354 :    
2355 :     The .cm file syntax uses a new keyword tool argument called "with".
2356 :     There are several ways of indicating the desired settings:
2357 :    
2358 :     foo.sml (with:parser.quotations=true)
2359 :     foo.sml (with:(name:parser.quotations value:true))
2360 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2361 :     foo.sml (with:(name1=value1 name2=value2 ...))
2362 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2363 :    
2364 :     etc.
2365 :    
2366 :     Another possible abbreviation is to leave out the =v or value:v part
2367 :     if the name refers to a boolean control (in which case the value is
2368 :     taken to be true). Thus, one could get lazy sml also by saying:
2369 :    
2370 :     foo.sml (with:parser.lazy-keyword=true)
2371 :     foo.sml (with:parser.lazy-keyword)
2372 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2373 :     foo.sml (with:(name:parser.lazy-keyword))

2725 :     Description:
2726 :    
2727 :     Changed the interface of structures Timer and Unix to match the most
2728 :     recent Basis spec.
2729 :    
2730 :     In the case of Unix there still seems to be an open/weird issue:
2731 :    
2732 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2733 :     fresh streams whenever they are called -- as opposed to have them
2734 :     return the same stream every time. This design is supposed to
2735 :     prevent space leaks caused by proc values hanging on to streams.
2736 :    
2737 :     The reap function, on the other hand, is supposed to close the
2738 :     streams. This cannot be done without having a handle on the
2739 :     stream in proc after all...
2740 :    
2741 :     I took the liberty to implement the following stopgap solution:
2742 :    
2743 :     The proc value hangs on to the most recently created stream(s).
2744 :     Reap closes those. If either or both of the two streams hadn't
2745 :     been created at all yet, then reap will close the corresponding
2746 :     file descriptors directly.
2747 :    
2748 :     PS: I don't understand the original space leak argument anymore. If
2749 :     a proc hangs on to the imperative stream, then I/O operations on those
2750 :     will advance the state of the cached stream and avoid the space leak.

2763 :     Tag: blume-20040525-group-owner
2764 :     Description:
2765 :    
2766 :     CM now ignores (but still accepts) the "owner" information in group
2767 :     descriptions. The owner of a group is its next enclosing
2768 :     library. Each group must have a unique owner. (There is a virtual
2769 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2770 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2771 :     and CM would check that such a declaration is correct. The new scheme
2772 :     is to have CM check that for each group there is precisely one owning
2773 :     library.
2774 :    
2775 :     The advantage of the new scheme is that the programmer no longer needs
2776 :     to maintain the somewhat annoying owner information. The downside is
2777 :     that CM cannot enforce the ownership rule across multiple runs of
2778 :     CM.make. Fortunately, enclosing the same group in two different
2779 :     libraries A and B which are not part of the same program does not
2780 :     cause real problems.

2804 :     gets rid of those at the end, so they don't accumulate under .cm.
2805 :    
2806 :     This required a minor change to install.sh because the name of the

2825 :     Added previously missing support for many socket-related functions
2826 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
2827 :     for the voluminous patch!
2828 :    
2829 :     (I have not tested this patch under win32 yet.)
2830 :    
2831 : mblume 1490 Here is David's e-mail:
2832 :    
2833 :     Hi,
2834 :    
2835 :     Attached to this email you find a diff against sml/nj 110.45
2836 :     that will enable socket support under Windows.
2837 :    
2838 :     To apply the patch (using unix or cygwin)
2839 :     1) gunzip runtime.diff.gz
2840 :     2) "cd" into "src/runtime" in the source tree of a fresh
2841 :     110.45 installation.
2842 :     3) patch -p 1 < [your/path/to]runtime.diff
2843 :    
2844 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2845 :     I only ran a few tests for basic socket client functionality
2846 :     (which worked fine). Especially the functions that use ioctl
2847 : mblume 1490 are not tested at all and might not work (see below).
2848 :    
2849 :     I implemented this since we want to move to a newer version of sml/nj
2850 :     but need socket support in order to use it. This is the first time I
2851 :     even had a look at the sml/nj source, so please review my changes
2852 :     before making this part of the distribution! Here are a few issues
2853 : blume 2155 that I think might be better for someone to solve who is more
2854 : mblume 1490 familiar with the sml/nj source (and socket programming):
2855 :    
2856 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2857 :     exception since I could not figure out what the windows equivalent
2858 :     of these functions is
2859 :    
2860 :     - In sockets-osdep.h there are a some #include statements that are
2861 :     only used in a few files that include sockets-osdep.h
2862 :    
2863 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2864 :     does not process its return value since I don't know how to
2865 :     report an error upwards.
2866 :    
2867 :     - It would probably be good to have a call to WSACleanup() when
2868 : blume 2155 the library is unloaded (if there is such a possibility).
2869 : mblume 1490 Otherwise I think Windows will take care of this automatically
2870 :     when the process finishes.
2871 :    
2872 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2873 :     no idea if that is actually the proper replacement on Windows.
2874 :    
2875 :     - All these issues are marked in the code by "FIXME" comments.
2876 :    
2877 : blume 2155 We use sml/nj extensively in our products and are quite happy
2878 :     with it. I hope this contribution will help you.
2879 : mblume 1490
2880 :     Keep up the good work!

2921 :     everything. (Notice that this refers to source code only. Compiled
2922 :     code is still only installed for modules that were requested explicitly
2923 :     or which are required for other modules that were requested explicitly.)

2958 :    
2959 :     Fixed the runtime so that ml-nlffi-lib runs on the cygwin version

2961 :    
2962 :     lib = dlopen(NULL, ...)
2963 :     f = dlsym(lib, "malloc");
2964 :    
2965 : blume 2155 does not work on Windows unless we explicitly export symbols
2966 :     such as 'malloc' during linking. We fixed this by explicitly
2967 : allenleung 1468 exporting the required symbols with the magic gcc incantation:
2968 :    
2969 :     -Wl,--export-all cygwin.def
2970 :    
2971 :     where cygwin.def is a file containing all the symbols that
2972 : blume 2155 we wish to export.
2973 : allenleung 1468
2974 : blume 2155 I suspect this is a Windows problem and we'll have to
2975 :     do the same (somehow with windows compilers) when
2976 : allenleung 1468 we build the native win32 version with the system
2977 : blume 2155 calls LoadLibrary/GetProcAddress.

3102 :     Tag: blume-20030926-ppautoload
3103 :     Description:
3104 :    
3105 :     I modified the read-eval-print loop so that the autoloader gets
3106 :     invoked whenever the prettyprinter tries to look up a symbol that
3107 :     is not currently defined in the toplevel environment but which
3108 :     appears in CM's autoload registry. As a result, we see far fewer of
3109 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3110 :    
3111 :     In addition to this I tried to clean up some pieces of the Basis
3112 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3113 :     instances of these ?.Foo.Bar.xxx names from being printed.
3114 :    
3115 :     The mechanism that picks names for types still needs some work, though.
3116 :     (Right now it seems that if there is a type A.t which is defined to
3117 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3118 :     "?.B.u" although the perhaps more sensible solution would be to use
3119 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3120 :     a chain of DEFtycs not farther than there are corresponding toplevel
3121 :     names in the current environment.)

3127 :     Description:
3128 :    
3129 :     Another installer tweak: All the ML code for the installer is now
3130 :     compiled during CMB.make and put into a little library called
3131 :     $smlnj/installer.cm. The installation then simply invokes
3132 :    
3133 :     sml -m $smlnj/installer.cm
3134 :    
3135 :     and everything happens automagically.
3136 :    
3137 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3138 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3139 :     and BINDIR.
3140 :    
3141 :     The new scheme guarantees that the ML code responsible for the installation
3142 :     is in sync with the APIs of the main system. Also, the installer is
3143 :     somewhat faster because the installer script is precompiled.

3155 :     structure.

3160 :     Tag: blume-20030924-sockets
3161 :     Description:
3162 :    
3163 :     1. Fixed SOCKET API and implementation to match Basis spec.
3164 :     This required changing the internal representation of sockets to one
3165 :     that remembers (for each socket file descriptor) whether it is currently
3166 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3167 :     call is made only if the state actually needs to change).
3168 :    
3169 :     2. OS-specific details of sockets were moved into separate files, thus
3170 :     making it possible to unify the bulk of the socket implementations
3171 :     between Unix and Win32.
3172 :    
3173 :     3. CML's socket API changed accordingly.
3174 :     (Note that we need to remove non-blocking functions from this API
3175 :     since they are redundant in the case of CML!)
3176 :    
3177 :     4. CML's socket implementation now makes use of non-blocking functions
3178 :     provided by Basis, thus removing all OS-dependent code from this part
3179 :     of CML.
3180 :    
3181 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3288 :     New working release 110.43. New bootfiles.

3293 :     Tag: blume-20030909-installer
3294 :     Description:
3295 :    
3296 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3297 :     Modified config/install.bat to take advantage of it. Also modified
3298 :     config/install.sh (and called it config/new-install.sh) to take advantage
3299 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3300 :     independent.)
3301 :    
3302 :     The installer can now install everything under Win32
3303 :     as well as under *nix as long as it compiles.
3304 :    
3305 :     Other changes:
3306 :    
3307 :     - made CML compile again under Win32
3308 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3309 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3310 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3311 :     same as type int; under Win32 it isn't
3312 :     - fixed some slice-related problems in the win32-specific parts of CML
3313 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3314 :     (under Win32, the volume name is case-insensitive, and the
3315 :     OS.Path code compares volume names for equality)

3321 :     Description:
3322 :    
3323 :     Made Win32 version of OS.FileSys.fullPath return current directory
3324 :     when given an empty string. This is what the spec says, and incidentally,
3325 :     CM depends on it. (CM otherwise goes into an infinite loop in certain
3326 :     cases when presented with the name of a non-existing .cm file.)

3331 : mblume 1352 Tag: blume-20030905-slices-etc
3332 : mblume 1350 Description:
3333 :    
3334 :     1. Changed interface to vectors and arrays in Basis to match
3335 :     (draft) Basis spec.
3336 :     2. Added signatures and implementations of slices according to
3337 :     Basis spec.
3338 :     3. Edited source code throughout the system to make it compile again
3339 :     under 1. and 2. (In some cases code had to be added to have it
3340 :     match the new signatures.)
3341 :     4. MLRISC should be backward-compatible: the copies of the originals
3342 :     of files that needed to change under 3. were retained, the .cm files
3343 :     check the compiler version number and use old versions when
3344 :     appropriate.
3345 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3346 :     dirstream -> string option (in accordance with Basis spec).
3347 :     6. When generating code that counts lines, ml-lex used function
3348 :     CharVector.foldli, taking advantage of its old interface.
3349 :     This has been replaced with the corresponding code from
3350 :     CharVectorSlice. (html-lex must be re-lexed!)
3351 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3352 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3353 :     8. Removed temporary additions (fromInternal, toInternal) from the
3354 :     (now obsolete) IntInf in smlnj-lib/Util.
3355 :     9. Cleaned up structure Byte.
3356 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3357 :     Cleaned/corrected implementation of Date.
3358 :     (Still need to check for correctness; implement better canonicalizeDate.)
3359 :     11. Added "scan" to signature IEEE_REAL.
3360 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3361 :     mod and rem when second operand is 2 (for parity checks).]
3362 :     13. Changed representation of type Time.time, using a single IntInf.int
3363 :     value counting microseconds. This considerably simplified the
3364 :     implementation of structure Time. We now support negative time
3365 :     values; scan and fromString handle signs.
3366 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3367 :     ArraySlice).

3372 :     Tag: blume-20030828-intinf
3373 :     Description:
3374 :    
3375 :     This is a major update which comes with a version number bump
3376 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3377 :     and an implementation of IntInf in the Basis.
3378 :    
3379 :     There are a fairly large number of related changes and updates throughout
3380 :     the system:
3381 :    
3382 :     Basis:
3383 :     - Implemented IntInf.
3384 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3385 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3386 : mblume 1347 - Added FixedInt as a synonym for Int32.
3387 :    
3388 :     compiler:
3389 :     * Added support for a built-in intinf type.
3390 :     - literals
3391 :     - pattern matching
3392 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3393 :     - overloading on literals and operations
3394 :    
3395 :     This required adding a primitive type intinf, some additional
3396 :     primops, and implementations for several non-trivial intinf
3397 :     operations in Core. (The intinf type is completely abstract
3398 :     to the compiler; all operations get delegated back to the Core.)
3399 :    
3400 :     * Intinf equality is handled by polyequal. However, the compiler
3401 :     does not print its usual warning in this case (since polyequal
3402 :     is the right thing to do there).
3403 :    
3404 :     * Improved the organization of structure InlineT.
3405 :    
3406 :     * A word about conversion primops:
3407 :     If conversions involving intinf do not cancel out during
3408 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3409 : mblume 1347 Since all core access must be resolved already during the FLINT
3410 :     translate phase, it would be too late a the time of CPS contract
3411 : mblume 1348 to add new Core calls. For this reason, conversion primops
3412 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3413 :     they are supposed to convert, and 2. the Core function that
3414 :     can help with this conversion if necessary. If CPS contract
3415 : mblume 1348 eliminates a primop, then the associated Core function becomes
3416 :     dead and goes away. Intinf conversion primops that do not get
3417 :     eliminated by CPS contract get rewritten into calls of their
3418 :     core functions by a separate, new phase.
3419 : mblume 1347
3420 :     interactive system:
3421 :     - Control.Print.intinfDepth controls max length of intinf constants
3422 :     being printed. (Analogous to Control.Print.stringDepth.)
3423 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3424 :     duplicates; replaced some of the code with code that makes better
3425 :     use of library functionality.
3426 :    
3427 :     CM:
3428 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3429 :     are no longer silent.
3430 :    
3431 :     CKIT:
3432 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3433 :     in favor of LargeInt -- which is now the same as IntInf.
3434 :     CKIT-knowledgable people should check whether this is what's
3435 :     intended and otherwise change things back to using Int32 or
3436 :     FixedInt.
3437 :    
3438 :     Throughout the code:
3439 : mblume 1348 Started using IntInf.int literals and built-in operations
3440 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3450 :     These changes involve replacement of the emulated old prettyprinter

3452 :     of a couple of bugs (895, 1186) relating to error messages. A new

3459 :     Tag: blume-20030811-windows
3460 :     Description:
3461 :    
3462 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3463 :    
3464 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3465 :    
3466 :     This patch restores SML/NJ's ability to run under win32. There are a
3467 :     number of changes, including fixes for several bugs that had gone
3468 :     unnoticed until now:
3469 :    
3470 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3471 :     trying to run the win32 version from within cygwin.)
3472 :    
3473 :     - There are a number of simple .bat scripts that substitute for their
3474 :     corresponding Unix shell-scripts. (See below.)
3475 :    
3476 :     - The internals of ml-build have been modified slightly. The main
3477 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3478 :     using OS.Process.system, the ML process delegates this task back
3479 :     to the script. Otherwise problems arise in mixed environments such
3480 :     as Cygwin where scripts look and work like Unix scripts, but
3481 :     where OS.Process.system cannot run them.
3482 :    
3483 :     - In CM, the srcpath pickler used native pathname syntax -- which
3484 :     is incorrect in the case of cross-compilation. The new pickle format
3485 :     is independent of platform-specific naming conventions.
3486 :    
3487 :     - Path configuration files (such as lib/pathconfig) can now choose
3488 :     between native and standard syntax. Placing a line of the form
3489 :    
3490 :     standard!
3491 :    
3492 :     into the file causes all subsequent paths to be interpreted using
3493 :     CM standard pathname syntax (= Unix conventions); a line
3494 :    
3495 :     native!
3496 :    
3497 :     switches back to native style. This was needed so that
3498 :     path config files can be written portably, see src/system/pathconfig.
3499 :    
3500 :     - Runtime system:
3501 :    
3502 :     - win32-filesys.c: get_file_time and set_file_time now
3503 :     access modification time, not creation time.
3504 :    
3505 :     - I/O code made aware of new array representation.
3506 :    
3507 :     - Bug fixes in X86.prim.masm.
3508 :    
3509 :     - src/system/makeml made aware of win32. (For use under cygwin
3510 :     and other Unix-environments for windows.)
3511 :    
3512 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3513 :     which caused BinIO.inputAll to fail consistently.
3514 :    
3515 :     .bat scripts:
3516 :    
3517 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3518 :    
3519 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3520 :     applications (sml, ml-yacc, ml-lex).
3521 :     - ml-build.bat: analogous to ml-build.
3522 :     - config\install.bat: Analogous to config/install.sh. This requires
3523 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3524 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3525 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3526 :     and the bootfile hierarchy must have been unpacked under
3527 :     sml.boot.x86-win32.
3528 :     The script is very primitive and does a poor job at error checking.
3529 :     It only installs the base system, ml-lex, and ml-yacc. No other
3530 :     libraries are being installed (i.e., you get only those that
3531 :     are part of the compiler.)
3532 :     - link-sml.bat: analogous to .link-sml, but not currently used
3533 :    
3534 :     Unrelated bug fixes:
3535 :    
3536 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3537 :     types.
3538 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3539 :     otherwise.)

3563 :     Description:
3564 :    
3565 :     Two changes:
3566 :    
3567 :     1. Added a flag for controlling whether non-exhaustive bindings will
3568 :     be treated as errors (default is false).
3569 :     2. Cleaned up the *entire* source tree so that CMB.make goes through
3570 :     without a single non-exhaustive match- or bind warning.

3576 :     Description:
3577 :    
3578 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3579 :    
3580 :     This mainly affects the quality of error messages. However, some
3581 :     of the code is now more straightforward than before. (Treatment of
3582 :     the above four constructs in translate.sml is much simpler than
3583 :     the "macro-expansion" that was going on before. Plus, the mach-
3584 :     compiler no longer gets invoked just to be able to compile an
3585 :     if-expression.)
3586 :    
3587 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3588 :     interactive loop.

3606 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3607 :

3671 :     (see below).
3672 :    
3673 :     The change solves a problem with two competing approaches the
3674 :     configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
3675 :     each other's way.
3676 :    
3677 :     This change only affects the runtime system code and the installer script.
3678 :     (No new bootfiles.)

3692 :     Description:
3693 :    
3694 :     The mltree operator DIVS must be implemented with an overflow check on
3695 :     the PPC because the hardware indicates divide-by-zero using "overflow" as
3696 :     well.

3702 :     Description:
3703 :    
3704 :     Sml now senses the SMLNJ_HOME environment variable. If this is set,
3705 :     then the bin dir is assumed to be in $SMLNJ_HOME/bin and (unless
3706 :     CM_PATHCONFIG is also set), the path configuration file is assumed
3707 :     to be in $SMLNJ_HOME/lib/pathconfig. This way one can easily move
3708 :     the entire tree to some other place and everything will "just work".
3709 :    
3710 :     (Companion commands such as ml-build and ml-makedepend also sense this
3711 :     variable.)

3764 :    
3765 :     Another small change is that ppDec tries to give more information
3766 :     than just "<sig>" in the case of functors. However, this code is
3767 :     broken in some mysterious way if the functor's body's signature
3768 :     has not been declared by ascription but gets inferred from the
3769 :     implementation. This needs fixing...

3837 :     - Fixed messed-up controls priorities.
3838 :    
3839 :     * Removed again all the stuff from config/preloads that one wouldn't
3840 :     be able to preload at the time the initial heap image is built.
3841 :     (Many libraries, e.g., CML, do not exist yet at this time. The

3868 :     Description:
3869 :    
3870 :     0. John Reppy made several modifications to the SML/NJ library.
3871 :     In particular, there is a shiny new controls-lib.cm.
3872 :    
3873 :     1. Pushed new controls interface through compiler so that everything
3874 :     compiles again.
3875 :    
3876 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3877 :     SML/NJ library (so that CML compiles again).
3878 :    
3879 :     3. Modified init scripts because XXX_DEFAULT environment variables
3880 :     are no longer with us. (Boot-time initialization is now done
3881 :     using the same environment variables that are also used for
3882 :     startup-time initialization of controls.)

3887 :     Tag: george-20020515-pseudo-op-decls
3888 :     Description:
3889 :    
3890 :     All pseudo-ops emitted before the first segment declaration
3891 :     such as TEXT, DATA, and BSS directives are assumed to be global
3892 :     declarations and are emitted first in the assembly file. This is
3893 :     useful in a number of situations where one has pseudo-ops that are not
3894 :     specific to any segment, and also works around the constraint that one
3895 :     cannot have client pseudo-ops in the TEXT segment.
3896 :    
3897 :     Because no segment is associated with these declarations it is
3898 :     an error to allocate any space or objects before the first segment
3899 :     directive and an exception will be raised. However, we cannot make
3900 :     this check for client pseudo-ops.
3901 :    
3902 :     These top level declarations are a field in the CFG graph_info.
3903 :     In theory you can continue to add to this field after the CFG has been
3904 :     built -- provided you know what you are doing;-)

3914 :     - Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
3915 :     (Bogus printouts for redefined bindings still occur. Compiler
3916 :     bug should no longer occur now. We need to redo the prettyprinter
3917 :     from scratch.)

3927 :     Description:
3928 :    
3929 :     Applied the following bugfix provided by Emden Gansner:
3930 :    
3931 :     Output is corrupted when outputSubstr is used rather than output.
3932 :    
3933 : blume 2155 The problem occurs when a substring
3934 : blume 1189
3935 :     ss = (s, dataStart, dataLen)
3936 :    
3937 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3938 :     avail bytes of s, starting at index dataStart, are copied into the
3939 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3940 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3941 :     starting this copy at index dataStart+avail in s, the current code
3942 : blume 1189 starts the copy at index avail.
3943 :    
3944 :     Fix:
3945 :     In text-io-fn.sml, change line 695 from
3946 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3947 : blume 2155 to

3964 :     Description:
3965 :    
3966 :     Added full support for div/mod/rem/quot on the x86, using the machine
3967 :     instruction's two results (without clumsily recomputing the remainder)
3968 :     directly where appropriate.
3969 :    
3970 :     Some more extensive power-of-two support was added to the x86 instruction
3971 :     selector (avoiding expensive divs, mods, and muls where they can be
3972 :     replaced with cheaper shifts and masks). However, this sort of thing
3973 :     ought to be done earlier, e.g., within the CPS optimizer so that
3974 :     all architectures benefit from it.
3975 :    
3976 :     The compiler compiles to a fixed point, but changes might be somewhat
3977 :     fragile nevertheless. Please, report any strange things that you might
3978 :     see wrt. div/mod/quot/rem...

3984 :     Description:
3985 :    
3986 :     Fixed my broken div/mod logic. Unfortunately, this means that the

3988 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3989 :     The problem was with quotient = 0, because that alone does not tell
3990 :     us which way the rounding went. One then has to look at whether
3991 :     remainder and divisor have the same sign... :(

4000 :    
4001 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
4002 :    
4003 :     Primops have changed. This means that the bin/boot-file formats have
4004 :     changed as well.
4005 :    
4006 :     To make sure that there is no confusion, I made a new version.
4007 :    
4008 :    
4009 :     CHANGES:
4010 :    
4011 :     * removed REMT from mltree (remainder should never overflow).
4012 :    
4013 :     * added primops to deal with divisions of all flavors to the frontend
4014 :    
4015 :     * handled these primops all the way through so they map to their respective
4016 :     MLRISC support
4017 :    
4018 :     * used these primops in the implementation of Int, Int32, Word, Word32
4019 :    
4020 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
4021 :    
4022 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
4023 :    
4024 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
4025 :     floating point
4026 :    
4027 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
4028 :     and Real (but Real.abs maps to a separate floating-point-only primop)
4029 :    
4030 :    
4031 :     TODO items:
4032 :    
4033 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
4034 :     instructions because the machine instruction encoder cannot handle
4035 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
4036 :     REM in the first place, and REM is supported by the x86 machine coder.)
4037 :    
4038 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
4039 :     selection phase. (The two can be streamlined because the hardware
4040 :     delivers both quotient and remainder at the same time anyway.)
4041 :    
4042 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
4043 :     (Currently the behavior is inconsistent both across architectures and
4044 :     wrt. the draft Basis spec.)
4045 :    
4046 :     * Word8 should eventually be handled natively, too.
4047 :    
4048 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
4049 :     as if there currently is no execution path that could trigger it in
4050 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
4051 :     hold for things like multiplication and division.)

4056 :     Tag: blume-20020327-mlrisc-divisions
4057 :     Description:
4058 :    
4059 :     Added support for all four division operations (ML's div, mod, quot,
4060 :     and rem) to MLRISC. In the course of doing so, I also rationalized
4061 :     the naming (no more annoying switch-around of DIV and QUOT), by
4062 :     parameterizing the operation by div_rounding_mode (which can be either
4063 :     DIV_TO_ZERO or DIV_TO_NEGINF).
4064 :    
4065 :     The generic MLTreeGen functor takes care of compiling all four
4066 :     operations down to only round-to-zero div.
4067 :    
4068 :     Missing pieces:
4069 :    
4070 :     * Doing something smarter than relying on MLTreeGen on architectures
4071 :     like, e.g., the x86 where hardware division delivers both quotient and
4072 :     remainder at the same time. With this, the implementation of the
4073 :     round-to-neginf operations could be further streamlined.
4074 :    
4075 :     * Remove inlining support for div/mod/rem from the frontend and replace it
4076 :     with primops that get carried through to the backend. Do this for all
4077 :     int and word types.

4082 :     Tag: blume-20020325-divmod
4083 :     Description:
4084 :    
4085 :     I improved (hopefully without breaking them) the implementation of Int.div,
4086 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
4087 :     advantage of the following observations:
4088 :    
4089 :     Let q = x quot y r = x rem y
4090 :     d = x div y m = x mod y
4091 :    
4092 :     where "quot" is the round-to-zero version of integer division that
4093 :     hardware usually provides. Then we have:
4094 :    
4095 :     r = x - q * y where neither the * nor the - will overflow
4096 :     d = if q >= 0 orelse x = q * y then q else q - 1
4097 :     where neither the * nor the - will overflow
4098 :     m = if q >= 0 orelse r = 0 then r else r + y
4099 :     where the + will not overflow
4100 :    
4101 :     This results in substantial simplification of the generated code.

4103 :     for

4146 :     Description:
4147 :    
4148 :     1. Changes to FLINT primops:
4149 :    
4150 :     (* make a call to a C-function;
4151 :     * The primop carries C function prototype information and specifies
4152 :     * which of its (ML-) arguments are floating point. C prototype
4153 :     * information is for use by the backend, ML information is for
4154 :     * use by the CPS converter. *)
4155 :     | RAW_CCALL of { c_proto: CTypes.c_proto,
4156 :     ml_args: ccall_type list,
4157 :     ml_res_opt: ccall_type option,
4158 :     reentrant : bool
4159 :     } option
4160 :     (* Allocate uninitialized storage on the heap.
4161 :     * The record is meant to hold short-lived C objects, i.e., they
4162 : blume 2155 * are not ML pointers. With the tag, the representation is
4163 : leunga 1174 * the same as RECORD with tag tag_raw32 (sz=4), or tag_fblock (sz=8)
4164 :     *)
4165 : blume 2155 | RAW_RECORD of {tag:bool,sz:int}
4166 : leunga 1174 and ccall_type = CCALL_INT32 | CCALL_REAL64 | CCALL_ML_PTR
4167 :    
4168 :     2. These CPS primops are now overloaded:
4169 :    
4170 :     rawload of {kind:numkind}
4171 :     rawstore of {kind:numkind}
4172 :    
4173 :     The one argument form is:
4174 :    
4175 :     rawload {kind} address
4176 :    
4177 :     The two argument form is:
4178 : blume 2155
4179 : leunga 1174 rawload {kind} [ml object, byte-offset]
4180 :    
4181 :     3. RAW_CCALL/RCC now takes two extra arguments:
4182 :    
4183 :     a. The first is whether the C call is reentrant, i.e., whether
4184 :     ML state should be saved and restored.
4185 :     b. The second argument is a string argument specifying the name of
4186 :     library and the C function.
4187 :    
4188 :     These things are currently not handled in the code generator, yet.
4189 :    
4190 :     4. In CProto,
4191 :    
4192 : blume 2155 An encoding type of "bool" means "ml object" and is mapped into
4193 :     C prototype of PTR. Note that "bool" is different than "string",
4194 : leunga 1174 even though "string" is also mapped into PTR, because "bool"
4195 :     is assigned an CPS type of BOGt, while "string" is ass
