449 :     Date: 2007/05/31 11:40:00 CDT
450 :     Description:
451 :    
452 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
453 :    
454 :     Also, changed the handling of "no core access": When translate.sml
455 :     needs access to a core exception at a time when the core has not
456 :     been set up yet (this only happens when compiling system/smlnj/init/*),
457 :     then don't bother generating the corresponding tests.
458 :    
459 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
460 :     the exception. Unfortunately, that confuses the plambda type checker.
461 :     Moreover, it does not do any good, because at runtime we don't expect
462 :     such an exception to be ever raised. (The code in system/smlnj/init/*
463 :     has to be written very carefully with this in mind!)

475 :     Description:
476 :    
477 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
478 :     with an explicit test for zero division. This should fixes several
479 :     regressions and makes it possible for downstream optimization phases
480 :     to treat these operations as "pure" when they are applied to unsigned
481 :     operands.

487 :    
488 :     Added the new MLRISC code generator for the AMD64. This version,

490 :     for all floating-point computations.

496 :    
497 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes

503 :     Date: 2007/05/23 22:30:00 CDT
504 :     Description:
505 :    
506 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
507 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
508 :    
509 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
510 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
511 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
512 :     while running CMB.make. The point is that the single symbol
513 :     NO_PLUGINS is definde in all three cases.)
514 :    
515 :     I changed the three locations within the sources that get compiled
516 :     during CMB.make where ml-yacc or ml-lex input is processed: When
517 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
518 :     is bypassed.
519 :    
520 :     When bootstrapping new versions of the compiler, there can be
521 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
522 :     are not available or otherwise not operational. In this case one can
523 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
524 :     do so, the following command should be issued at the interactive
525 :     prompt:
526 :    
527 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
528 :    
529 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
530 :     files that normally would be generated by ml-yacc and ml-lex.
531 :     (Copies of these files are in the repository.)

547 :     Description:
548 :    
549 :     Changed the installation mechanism for CM tool plugins. These are
550 :     just libaries and now get installed like ordinary libaries.
551 :    
552 :     There are now a number of new installation targets that give some
553 :     fine-grain control over what classes and suffixes are known, and what
554 :     they will map to.
555 :     See config/targets for details.
556 :    
557 :     The code that caused plugin installation as part of running a
558 :     tool's "build" script has been removed. (The build script is for
559 :     building, not for installing.)

564 :     Description:
565 :    
566 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
567 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
568 :     CM fail if a shell tool reports a non-success exit status. If
569 :     the control is set to true, then CM will press on after tool failures
570 :     in the event that the target files exist (even though they are
571 :     considered outdated). Turning the control to true can be useful for
572 :     bootstrapping.

577 :     Description:
578 :    
579 :     Merge of ml-lpt revisions for 110.64.
580 :    
581 :     The name of several ml-lpt-lib modules has changed:
582 :     Repair => AntlrRepair
583 :     StreamPos => AntlrStreamPos
584 :     ErrHandlerFn => AntlrErrHandler
585 :     EBNF => AntlrEBNF
586 :    
587 :     The ml-antlr specification format has changed: declarations such as
588 :     %tokens and nonterminal definitions can occur *multiple* times in the
589 :     same specification. The semantics are such that each new declaration
590 :     extends the previous ones. This does not apply to %start or %name,
591 :     of course.
592 :    
593 :     Importing a grammar via %import now includes *all* declarations in from
594 :     the imported grammar, except for %name, %entry, and %start. Tokens
595 :     and nonterminals can be dropped using the new %dropping clause of the
596 :     %import directive; the separate %drop and %extend have been removed.
597 :    
598 :     We now allow optional type annotations on nonterminals, using the %nonterms
599 :     directive as in ml-yacc.
600 :    
601 :     The refcell construct is now implemented using SML's regular reference
602 :     cells, so the :== and !! notation has been deprecated.
603 :    
604 :     The ml-antlr tool now does much more checking of specifications, and
605 :     its error messages have been greatly improved. Error repair for
606 :     generated parsers has been completely rewritten, and is now both
607 :     much faster and more accurate.
608 :    
609 :     ml-ulex is now more lenient with escape codes (non-SML-standard
610 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
611 :     Also, character classes may now include a "-" character at the beginning
612 :     as is standard in most other regexp tools.
613 :    
614 :     All of these changes are documented in the user guide, which has
615 :     been updated and improved with this merge.

767 :    
768 :     Added preliminary support in MLRISC for Staged Allocation, a technique
769 :     for specifying calling conventions (see

771 :     Initially, we plan to use this code to generate C calls for the AMD64.
772 :    
773 :     The staged allocation code base resides in MLRISC/staged-allocation,

839 :     Description:
840 :    
841 :     Brought ml-lpt manual up-to-date with the code. Many minor
842 :     improvements to the tools, and a few minor bugfixes. Prepared
843 :     ml-lpt-lib for integration with new UTF8 structure. Changed
844 :     the interface for creating streams in ml-ulex (we now support
845 :     stream creation from several kinds of sources). Overall, the
846 :     tools are now quite stable, and their interfaces are unlikely to
847 :     change in a way that would break compatibility. More work,
848 :     however, is needed in the documentation.

853 :     Description:
854 :    
855 :     Implemented library installer. Moved CM plugin code for
856 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
857 :     their respective trees. Implemented CM plugin for ml-ulex
858 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
859 :     and ml-antlr.
860 :    
861 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
862 :     CM tools. (It turns out to be too messy to do otherwise because
863 :     there is too much code that during installation relies on the presence
864 :     of these tools -- resulting in a tricky ordering problem.)

871 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
872 :     Modified CM's startup code to use shiftArgs as it processes
873 :     command line arguments. This way, the init code in each .sml-file
874 :     or library that is mentioned at the top level will see only
875 :     those arguments that have not yet been processed at this point.
876 :     In other words, the init code can "seize control" and process the
877 :     remaining command line.

943 :     Date: 2006/12/08 09:50:00 CST
944 :     Description:
945 :    
946 :     Added code to CM's "standard shell tool" implementation which
947 :     causes it to tolerate (with a warning) the situation where the shell
948 :     command fails (e.g., due to the shell command's non-existence)
949 :     as long as all target files exist.
950 :    
951 :     This makes it possible to, e.g., build ml-yacc from sources even if
952 :     svn checkout messed up the time stamps on files in such a way that
953 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
954 :     be needed to re-process yacc.grm, but obviously it might not yet be
955 :     available at that time.)

961 :    
962 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
963 :     recvVecFromNB' in the SOCKET signature. This error is actually
964 :     in the SML Basis specification too.

994 :     Tag: release-110.60
995 :     Description:
996 :    
997 :     New working release (110.60). NEW BOOTFILES!
998 :    
999 :     This is the first subversion-hosted release. There are also changes
1000 :     to the directory layout. Here is a table:
1001 :    
1002 :     (All pathnames are relative to the SML/NJ "root" directory.)
1003 :    
1004 :     config -> config
1005 :    
1006 :     src/cm -> base/cm
1007 :     src/compiler -> base/compiler
1008 :     src/runtime -> base/runtime
1009 :     src/system -> base/system
1010 :    
1011 :     src/cm/pgraph -> pgraph
1012 :    
1013 :     src/READMES -> base/READMES
1014 :     src/$notefile -> base/NOTES/$notefile
1015 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1016 :     MACOSXINSTALL WININSTALL
1017 :    
1018 :     src/smlnj-lib -> smlnj-lib
1019 :     src/MLRISC -> MLRISC
1020 :     ckit -> ckit
1021 :     src/cml -> cml
1022 :     src/eXene -> eXene
1023 :     src/heap2asm -> heap2asm
1024 :     src/lexgen -> lexgen
1025 :     src/ml-burg -> ml-burg
1026 :     src/ml-lex -> ml-lex
1027 :     src/ml-yacc -> ml-yacc
1028 :     src/ml-nlffi-lib -> nlffi/lib
1029 :     src/ml-nlffigen -> nlffi/gen
1030 :     src/smlnj-c -> smlnj-c
1031 :     src/tools/TraceDebugProf -> trace-debug-profile
1032 :    
1033 :     In addition, there is also a new
1034 :    
1035 :     ml-lpt
1036 :    
1037 :     directory containing two new program generator tools: ml-ulex and
1038 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1039 :     LL(k) parser generator). These tools are currently "beta-quality"
1040 :    
1041 :     The latest versios of the sources can now be obtained anonymously
1042 :     via subversion. For this, it is useful to first check out
1043 :    
1044 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1045 :    
1046 :     and put the resulting directory on your shell's PATH. This provides
1047 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
1048 :     and refresh-all.sh.
1049 :    
1050 :     To create a freshly checked-out copy of the sources, do
1051 :    
1052 :     checkout-all.sh [dir]
1053 :    
1054 :     where dir is the optional SML/NJ root directory (default is ".").
1055 :    
1056 :     This creates the above directory layout. Each subdirectory of
1057 :     the root is under individual subversion control. The stat-all.sh
1058 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
1059 :     each of these subtrees.
1060 :

1062 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
1063 : blume 2155 Date: 2006/11/02 12:20:00 CST
1064 :     Description:
1065 :    
1066 :     Reorganized directory layout.
1067 :    
1068 :     This is a temporary solution, more reorganization is to come.
1069 :    
1070 :     The basic idea is to have a number of toplevel trees, each corresponding
1071 :     to a well-defined part of the overall system. Each part can be
1072 :     maintained individually, even in separate source repositories,
1073 :     although currently we still serve everything out of the main
1074 :     smlnj-gforge tree.
1075 :    
1076 :     Installer and and scripts have been updated to reflect the new
1077 :     layout. The installer (base/src/system/smlnj/installer) is now
1078 :     "scriptable" to avoid burning too much knowledge about the
1079 :     layout into SML source code. The main script used by the installer
1080 :     is in config/actions.
1081 :    
1082 :     The main change is that many of the subdirectories of what used to
1083 :     be known as "src" have moved to the toplevel. The "src" directory
1084 :     itself has moved down into a subtree called "base". (We may eventually
1085 :     get rid of the extra level of indirection represented by "src".)
1086 :    
1087 :     The layout is now as follows:
1088 :    
1089 :     toplevel tree name | default repository
1090 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1091 :     -------------------+----------------------------------------------------
1092 :     config | $gf/config/trunk
1093 :     |
1094 :     base | $gf/sml/trunk
1095 :     |
1096 :     smlnj-lib | $gf/smlnj-lib/trunk
1097 :     MLRISC | $gf/MLRISC/trunk
1098 :     |
1099 :     ml-yacc | $gf/ml-yacc/trunk
1100 :     ml-lex | $gf/ml-lex/trunk
1101 :     ml-burg | $gf/ml-burg/trunk
1102 :     lexgen | $gf/lexgen/trunk
1103 :     heap2asm | $gf/heap2asm/trunk
1104 :     |
1105 :     cml | $gf/cml/trunk
1106 :     eXene | $gf/eXene/trunk
1107 :     ckit | $gf/ckit/trunk
1108 :     nlffi | $gf/nlffi/trunk
1109 :     |
1110 :     smlnj-c | $gf/smlnj-c/trunk
1111 :    
1112 :     In $gf/admin there are a few useful shell scripts for checking out
1113 :     and maintaining the entire collection of trees:
1114 :    
1115 :     admin/checkout-all.sh [dir]
1116 :     -- optionally creates dir and checks out all trees from their
1117 :     default repositories; if dir is missing, checkout into .
1118 :     admin/refresh-all.sh [dir]
1119 :     -- looks at all trees (from the above list) in dir (default: .)
1120 :     and runs "svn update" if the tree exists and is under
1121 :     subversion control;
1122 :     non-existing or non-subversion trees are skipped
1123 :     admin/stat-all.sh [dir]
1124 :     -- like refresh-all.sh, but runs "svn stat" instead

1304 :     Description:
1305 :    
1306 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1307 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1308 : blume 2155 at the time when config/preloads is processed, the library has to
1309 : mblume 1878 be referred to by another name. In 110.57 this would be
1310 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1311 :     to be valid as well.)
1312 :    
1313 :     Thanks to Todd Wilson (Fresno) for alerting me to this issue.

1366 :     Tag: blume-22051115-versiontool
1367 :     Description:
1368 :    
1369 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1370 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1371 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1372 :     it. Instead, it has the status of "user code", so it should use
1373 :     $/basis.cm to refer to the Basis library. (At least that's true for
1374 :     the purpose of bootstrapping the previous change. In the future it
1375 :     might make sense to have versiontool.cm refer to
1376 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1377 :     compiler itself uses.)
1378 :    
1379 :     Also patched src/system/testml to have it activate those extra anchor
1380 :     bindings in config/extrapathconfig.

1385 :     Tag: blume-22051115-libraries
1386 :     Description:
1387 :    
1388 :     This change affects the way the following libraries are tied into
1389 :     the system:
1390 :    
1391 :     $/basis.cm
1392 :     $/smlnj-lib.cm
1393 :     $/pp-lib.cm
1394 :     $/controls-lib.cm
1395 :     $/html-lib.cm
1396 :     $/ml-yacc-lib.cm
1397 :    
1398 :     These libraries are now internally (as seen from the source code
1399 :     of the implementation itself) known by the following names:
1400 :    
1401 :     $smlnj/basis/basis.cm
1402 :     $smlnj/smlnj-lib/smlnj-lib.cm
1403 :     $smlnj/smlnj-lib/pp-lib.cm
1404 :     $smlnj/smlnj-lib/controls-lib.cm
1405 :     $smlnj/smlnj-lib/html-lib.cm
1406 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1407 :    
1408 :     This makes it possible to work with code that requires different
1409 :     versions of these libraries, and which refers to these libraries using
1410 :     their "default" names (i.e., the first set of names above). In other
1411 :     words, one can un-define or re-define those default names without
1412 :     compromising the proper functioning of the compiler itself.
1413 :    
1414 :     A similar procedure had already been performed for several of the
1415 :     MLRISC libraries that are linked into the compiler. I did some
1416 :     cleanup on this code.
1417 :    
1418 :     A new file in the config directory (named extrapathconfig) is
1419 :     responsible for setting up path anchors that the compiler itself does
1420 :     not need, but that are typically required by user code.

1600 :     Description:
1601 :    
1602 :     Added mechanism for re-creating a heap file for the interactive system
1603 :     after configuration variables have been changed.
1604 :    
1605 :     CM.redump_heap : string -> unit
1606 :    
1607 :     This is much like SMLofNJ.exportML, but starting from the resulting
1608 : blume 2155 heap does not return to the caller of CM.redump_heap but
1609 : mblume 1792 restarts the interactive system from scratch. The original call of
1610 :     CM.redump_heap does not return but ends the interactive session.
1611 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1612 :    
1613 :     Internally, redump_heap winds the dynamic execution context back to
1614 :     the point where the original heap image was created and re-executes
1615 :     the heap image generation code in the boot code.

1732 :     Description:
1733 :    
1734 :     Implemented new (but still experimental) heap2exec facility. This is
1735 :     tested under Mac OS X and should work under Linux (will test shortly).
1736 :     It will probably also work on the Sparc (will test some time later).
1737 :    
1738 :     - removed old "HACKED_STANDALONE" hack from runtime
1739 :    
1740 :     To be able to test this, uncomment the request for "heap2asm" in
1741 :     config/targets prior to installation. (Notice that this is different
1742 :     from "heap2exec" mentioned below. Not a typo.)
1743 :    
1744 :     To perform an actual test, run the command
1745 :    
1746 :     $ bin/heap2exec heapfile execfile
1747 :    
1748 :     (You can put heap2exec on your shell's path.)
1749 :    
1750 :     For example, run
1751 :    
1752 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1753 :    
1754 :     This will create a standalone executable called "mly" which you can
1755 :     then invoke directly as a command.

1782 :    
1783 :     * Fixed CM's incorrect assumption that the PPC is little-endian.

1900 :     Tag: blume-20041124-position
1901 :     Description:
1902 :    
1903 :     The compiler can now be compiled in a mode that makes structure Position
1904 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1905 :     for the time being.
1906 :    
1907 :     To enable 64-bit positions, use the following procedure:
1908 :    
1909 :     1. Start sml
1910 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1911 :     3. Type
1912 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1913 :     4. Run CMB.make() as usual.
1914 :    
1915 :     This is barely tested. The only test so far was a little SML program
1916 :     counting the number of characters in an 8-gigabyte file by
1917 :     reading it character-by-character. That test was successful.
1918 :    
1919 :     In support of 64-bit positions, a number of new functions have been
1920 :     added to the runtime system.

1965 :    
1966 :     - In a previous commit, fixed a minor issue with how polyequal is being
1967 :     translated. In particular, the code now "looks through" abstractions.
1968 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1969 :     more efficient code. Important examples for where this matters are
1970 :     the new int64 and word64 types.

1989 :     but for the time being they don't even make sense because LargeWord is
1990 :     32-bit wide.)

1992 :     Also started to add similar support for Int64, but major pieces of that
1993 :     are still missing.

1999 :     Description:
2000 :    
2001 :     Structure Word64 is now (almost) complete, word literals and patterns
2002 :     seem to work. There are a few odd pieces missing. In particular,
2003 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2004 :     at the moment.
2005 :    
2006 :     Making Word64 official would mean that LargeWord becomes Word64. But
2007 :     this requires extreme care because most word-word conversions have to
2008 :     go through LargeWord, so making a mistake means loss of efficiency or
2009 :     worse. Eventually there will be a solution similar to (but actually
2010 :     simpler than) what I did with IntInf.

2046 :     - Default contents of config/srcarchiveurl uses $VERSION and
2047 :     normally does not have to be edited to reflect a version change.
2048 :    
2049 :     (As a result, a version change can be done by just editing

2090 :     Tag: blume-20041020-standalone-backtrace
2091 :     Description:
2092 :    
2093 :     Added a mechanism for getting back-trace information from standalone
2094 :     programs. Here is how it works:
2095 :    
2096 :     1. The part of the program from which you want to get backtrace
2097 :     information (usually the whole program) should be wrapped with
2098 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
2099 :     main program could be modified from something like
2100 :    
2101 :     fun main (pgm, args) = ...
2102 :    
2103 :     to
2104 :    
2105 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2106 :    
2107 :     2. To be able to access BackTrace.monitor, you have to add
2108 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
2109 :     main function.
2110 :    
2111 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2112 :     CM might have created in the past for your project).
2113 :    
2114 :     4. Build the system using this command line:
2115 :    
2116 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2117 :     myprog.cm MyProg.main myprog
2118 :    
2119 :     instead of the usual
2120 :    
2121 :     ml-build myprog.cm MyProg.main myprog
2122 :    
2123 :     I changed a library name:
2124 :    
2125 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2126 :    
2127 :     New libraries:
2128 :    
2129 :     $smlnj-tdp/back-trace.cm
2130 :     -- when loaded causes the back-trace plugin to be installed
2131 :     $smlnj-tdp/coverage.cm
2132 :     -- when loaded causes the coverage plugin to be installed
2133 :

2139 :

2148 :     Description:
2149 :    
2150 :     * Test coverage tool added!
2151 :     * Further reorganization of tracing-, debugging-, and profiling support:
2152 :    
2153 :     - moved original BTImp -- now called BackTrace -- into a separate
2154 :     library called $/trace-debug-profile.cm
2155 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2156 :     - only the instrumentation mechanism is now left in the compiler proper
2157 :     - BackTrace module is a plugin which is NOT plugged in by default
2158 :     - Coverage module is another such plugin
2159 :    
2160 :     To get the benefits of any of these plugin modules, the code in
2161 :     question must be compiled with tdp instrumentation turned on. This
2162 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2163 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2164 :    
2165 :     Plugins are selected at link time. (Pre-compiled instrumented code
2166 :     can be re-loaded with different plugins in effect.) When an
2167 :     instrumented module is linked, whatever plugins are at that time
2168 :     enabled will come into effect for that module.
2169 :    
2170 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2171 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2172 :     To enable the coverage plugin, load the same library and invoke
2173 :     Coverage.install().
2174 :    
2175 :     Back-traces are generated automatically on uncaught exceptions and
2176 :     when the code in question explicitly invokes BackTrace.trigger().
2177 :    
2178 :     Coverage (and execution frequency-) information must be queried
2179 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2194 :     Description:
2195 :    
2196 :     Some rationalization of names:
2197 :    
2198 :     structure BTrace -> structure TDPInstrument
2199 :     etc.
2200 :    
2201 :     This is is preparation of using the original back-trace
2202 :     instrumentation for other purposes. "TDP" stands for
2203 :     Trace/Debug/Profile.
2204 :    
2205 :     The control flag controlling whether instrumentation is on or off is now
2206 :     registered under a different name, so instead of running sml as
2207 :    
2208 :     sml -Cinstrument.btrace-mode=true
2209 :

2222 :     regions being reported in error- and debug messages.

2228 :     Description:
2229 :    
2230 :     Fixed handling of keywords in .cm files: After seeing "is" the lexer
2231 :     treats subsequent occurrences of "group", "library", "source", "is",
2232 :     "*", and "-" as ordinary identifiers rather than keywords.
2233 :    
2234 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool
2235 :     is supposed to accept a tool argument called "source", but this did
2236 :     not work because of the clash with the keyword.

2249 :     - simplified tokentable implementation

2268 :     Description:

2271 :     tool. (Still, since the master does two passes over the code for
2272 :     CMB.make, the release number gets bumped twice when slaves are
2273 :     attached. I don't know if this is worth fixing...)

2279 :     Description:
2280 :    
2281 :     * Moved the "version" magic into its own little library under
2282 : mblume 1672 src/system/smlnj/internal. This avoids expensive reconstruction of
2283 :     a stable src/compiler/core.cm.
2284 : mblume 1639
2285 : mblume 1672 * At the same time, structure CompilerVersion is now known as
2286 :     structure SMLNJVersion.
2287 : mblume 1639
2288 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2289 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2290 :     Also, loading the versiontool does not work when rebuilding the system
2291 :     because CM is not properly initialized at that time.

2296 :     Tag: blume-20040929-autoversion
2297 :     Description:
2298 :    
2299 :     Implemented some CM magic to have
2300 :     file src/compiler/TopLevel/main/version.sml
2301 :     generated automagically.
2302 :     The version is taken from two files: config/version and config/release.
2303 :     The first is expected to contain a two-part version number such as 110.49.
2304 :     The second should contain a single number, but it may be missing.
2305 :    
2306 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2307 :     time the version tool is loaded (which is the first time you say CMB.make),
2308 :     then the tool will increment the value stored in config/release every
2309 :     time CMB.make is invoked.
2310 :    
2311 :     The binfile format is now insensitive to anything beyond the first
2312 :     two components of a version number, so bumping the release does not render
2313 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2314 :     during development without invalidating existing binfiles.
2315 :    
2316 :     In any case, every CMB.make updates the date information in version.sml.
2317 :     (This is the date that is printed in the banner.)

2330 :     Tag: blume-20040927-controls
2331 :     Description:
2332 :    
2333 :     Added two pieces of functionality to the Controls interface:
2334 :    
2335 :     1. val save'restore: 'a control -> unit -> unit
2336 :    
2337 :     grabs the current value of the control in stage 1 and restores it
2338 :     in stage 2.
2339 :    
2340 :     2. val set' : 'a control * 'a -> unit -> unit
2341 :    
2342 :     stores the given value into the control in stage 2 (i.e., delayed)
2343 :     but does all error checking in stage 1.
2344 :     (This is for string controls that need to do parse their argument --
2345 :     something that might fail. In some cases, notably in CM, one
2346 :     already knows the intended argument but wants to delay the actual
2347 :     assignment until a time when error recovery would be more difficult.)
2348 :    
2349 :     Changed the handling of controls in tool arguments to classes "sml" and
2350 :     "lazysml":
2351 :     - use Controls.save'restore as a more robust way of restoring the
2352 :     old value (in particular: without having to re-parse the string)
2353 :     - use controls to handle the "overload" keyword in the init group
2354 :     (I believe this change actually fixes a long-standing obscure bug.)

2359 :     Tag: blume-20040927-lazysml
2360 :     Description:
2361 :    
2362 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2363 :     difference to "sml" is that compilation is done with Control.lazysml
2364 :     set to true. A source of class "lazysml" is automatically recognized
2365 :     by a file name suffix of ".lml".
2366 :    
2367 :     In addition to the above feature, the original class "sml" now also
2368 :     supports a tool argument "lazy" which has the same effect. As a
2369 :     result, the following three lines are equivalent:
2370 :    
2371 :     foo.sml : lazysml
2372 :     foo.sml : sml (lazy)
2373 :     foo.sml (lazy)
2374 :    
2375 :     The setting goes into effect both during parsing and during
2376 :     compilation. The original setting is restored right after parsing and
2377 :     after compilation, respectively.
2378 :    
2379 :     In addition to all the above, there is also a general mechanism to set
2380 :     ANY of the "controls" that are available at the command line via
2381 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2382 :     apply as well. (In fact, "lazy" is implemented as a special case of
2383 :     the general mechanism.)
2384 :    
2385 :     The .cm file syntax uses a new keyword tool argument called "with".
2386 :     There are several ways of indicating the desired settings:
2387 :    
2388 :     foo.sml (with:parser.quotations=true)
2389 :     foo.sml (with:(name:parser.quotations value:true))
2390 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2391 :     foo.sml (with:(name1=value1 name2=value2 ...))
2392 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2393 :    
2394 :     etc.
2395 :    
2396 :     Another possible abbreviation is to leave out the =v or value:v part
2397 :     if the name refers to a boolean control (in which case the value is
2398 :     taken to be true). Thus, one could get lazy sml also by saying:
2399 :    
2400 :     foo.sml (with:parser.lazy-keyword=true)
2401 :     foo.sml (with:parser.lazy-keyword)
2402 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2403 :     foo.sml (with:(name:parser.lazy-keyword))

2755 :     Description:
2756 :    
2757 :     Changed the interface of structures Timer and Unix to match the most
2758 :     recent Basis spec.
2759 :    
2760 :     In the case of Unix there still seems to be an open/weird issue:
2761 :    
2762 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2763 :     fresh streams whenever they are called -- as opposed to have them
2764 :     return the same stream every time. This design is supposed to
2765 :     prevent space leaks caused by proc values hanging on to streams.
2766 :    
2767 :     The reap function, on the other hand, is supposed to close the
2768 :     streams. This cannot be done without having a handle on the
2769 :     stream in proc after all...
2770 :    
2771 :     I took the liberty to implement the following stopgap solution:
2772 :    
2773 :     The proc value hangs on to the most recently created stream(s).
2774 :     Reap closes those. If either or both of the two streams hadn't
2775 :     been created at all yet, then reap will close the corresponding
2776 :     file descriptors directly.
2777 :    
2778 :     PS: I don't understand the original space leak argument anymore. If
2779 :     a proc hangs on to the imperative stream, then I/O operations on those
2780 :     will advance the state of the cached stream and avoid the space leak.

2794 :     Description:
2795 :    
2796 :     CM now ignores (but still accepts) the "owner" information in group
2797 :     descriptions. The owner of a group is its next enclosing
2798 :     library. Each group must have a unique owner. (There is a virtual
2799 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2800 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2801 :     and CM would check that such a declaration is correct. The new scheme
2802 :     is to have CM check that for each group there is precisely one owning
2803 :     library.
2804 :    
2805 :     The advantage of the new scheme is that the programmer no longer needs
2806 :     to maintain the somewhat annoying owner information. The downside is
2807 :     that CM cannot enforce the ownership rule across multiple runs of
2808 :     CM.make. Fortunately, enclosing the same group in two different
2809 :     libraries A and B which are not part of the same program does not
2810 :     cause real problems.

2834 :     gets rid of those at the end, so they don't accumulate under .cm.

2862 :    
2863 :     Hi,
2864 :    
2865 :     Attached to this email you find a diff against sml/nj 110.45
2866 :     that will enable socket support under Windows.
2867 :    
2868 :     To apply the patch (using unix or cygwin)
2869 :     1) gunzip runtime.diff.gz
2870 :     2) "cd" into "src/runtime" in the source tree of a fresh
2871 :     110.45 installation.
2872 :     3) patch -p 1 < [your/path/to]runtime.diff
2873 :    
2874 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2875 :     I only ran a few tests for basic socket client functionality
2876 :     (which worked fine). Especially the functions that use ioctl
2877 : mblume 1490 are not tested at all and might not work (see below).
2878 :    
2879 :     I implemented this since we want to move to a newer version of sml/nj
2880 :     but need socket support in order to use it. This is the first time I
2881 :     even had a look at the sml/nj source, so please review my changes
2882 :     before making this part of the distribution! Here are a few issues
2883 : blume 2155 that I think might be better for someone to solve who is more
2884 : mblume 1490 familiar with the sml/nj source (and socket programming):
2885 :    
2886 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2887 :     exception since I could not figure out what the windows equivalent
2888 :     of these functions is
2889 :    
2890 :     - In sockets-osdep.h there are a some #include statements that are
2891 :     only used in a few files that include sockets-osdep.h
2892 :    
2893 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2894 :     does not process its return value since I don't know how to
2895 :     report an error upwards.
2896 :    
2897 :     - It would probably be good to have a call to WSACleanup() when
2898 : blume 2155 the library is unloaded (if there is such a possibility).
2899 : mblume 1490 Otherwise I think Windows will take care of this automatically
2900 :     when the process finishes.
2901 :    
2902 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2903 :     no idea if that is actually the proper replacement on Windows.
2904 :    
2905 :     - All these issues are marked in the code by "FIXME" comments.
2906 :    
2907 : blume 2155 We use sml/nj extensively in our products and are quite happy

2994 :    
2995 : blume 2155 does not work on Windows unless we explicitly export symbols
2996 :     such as 'malloc' during linking. We fixed this by explicitly
2997 : allenleung 1468 exporting the required symbols with the magic gcc incantation:
2998 :    
2999 :     -Wl,--export-all cygwin.def
3000 :

3002 : blume 2155 we wish to export.
3003 : allenleung 1468
3004 : blume 2155 I suspect this is a Windows problem and we'll have to

3133 :     Description:
3134 :    
3135 :     I modified the read-eval-print loop so that the autoloader gets
3136 :     invoked whenever the prettyprinter tries to look up a symbol that
3137 :     is not currently defined in the toplevel environment but which
3138 :     appears in CM's autoload registry. As a result, we see far fewer of
3139 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3140 :    
3141 :     In addition to this I tried to clean up some pieces of the Basis
3142 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3143 :     instances of these ?.Foo.Bar.xxx names from being printed.
3144 :    
3145 :     The mechanism that picks names for types still needs some work, though.
3146 :     (Right now it seems that if there is a type A.t which is defined to
3147 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3148 :     "?.B.u" although the perhaps more sensible solution would be to use
3149 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3150 :     a chain of DEFtycs not farther than there are corresponding toplevel
3151 :     names in the current environment.)

3157 :     Description:
3158 :    
3159 :     Another installer tweak: All the ML code for the installer is now
3160 :     compiled during CMB.make and put into a little library called
3161 :     $smlnj/installer.cm. The installation then simply invokes
3162 :    
3163 :     sml -m $smlnj/installer.cm
3164 :    
3165 :     and everything happens automagically.
3166 :    
3167 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3168 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3169 :     and BINDIR.
3170 :    
3171 :     The new scheme guarantees that the ML code responsible for the installation
3172 :     is in sync with the APIs of the main system. Also, the installer is
3173 :     somewhat faster because the installer script is precompiled.

3190 :     Tag: blume-20030924-sockets
3191 :     Description:
3192 :    
3193 :     1. Fixed SOCKET API and implementation to match Basis spec.
3194 :     This required changing the internal representation of sockets to one
3195 :     that remembers (for each socket file descriptor) whether it is currently
3196 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3197 :     call is made only if the state actually needs to change).
3198 :    
3199 :     2. OS-specific details of sockets were moved into separate files, thus
3200 :     making it possible to unify the bulk of the socket implementations
3201 :     between Unix and Win32.
3202 :    
3203 :     3. CML's socket API changed accordingly.
3204 :     (Note that we need to remove non-blocking functions from this API
3205 :     since they are redundant in the case of CML!)
3206 :    
3207 :     4. CML's socket implementation now makes use of non-blocking functions
3208 :     provided by Basis, thus removing all OS-dependent code from this part
3209 :     of CML.
3210 :    
3211 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3323 :     Tag: blume-20030909-installer
3324 :     Description:
3325 :    
3326 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3327 :     Modified config/install.bat to take advantage of it. Also modified
3328 :     config/install.sh (and called it config/new-install.sh) to take advantage
3329 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3330 :     independent.)
3331 :    
3332 :     The installer can now install everything under Win32
3333 :     as well as under *nix as long as it compiles.
3334 :    
3335 :     Other changes:
3336 :    
3337 :     - made CML compile again under Win32
3338 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3339 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3340 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3341 :     same as type int; under Win32 it isn't
3342 :     - fixed some slice-related problems in the win32-specific parts of CML
3343 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3344 :     (under Win32, the volume name is case-insensitive, and the
3345 :     OS.Path code compares volume names for equality)

3355 :     CM depends on it. (CM otherwise goes into an infinite loop in certain

3361 : mblume 1352 Tag: blume-20030905-slices-etc
3362 : mblume 1350 Description:
3363 :    
3364 :     1. Changed interface to vectors and arrays in Basis to match
3365 :     (draft) Basis spec.
3366 :     2. Added signatures and implementations of slices according to
3367 :     Basis spec.
3368 :     3. Edited source code throughout the system to make it compile again
3369 :     under 1. and 2. (In some cases code had to be added to have it
3370 :     match the new signatures.)
3371 :     4. MLRISC should be backward-compatible: the copies of the originals
3372 :     of files that needed to change under 3. were retained, the .cm files
3373 :     check the compiler version number and use old versions when
3374 :     appropriate.
3375 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3376 :     dirstream -> string option (in accordance with Basis spec).
3377 :     6. When generating code that counts lines, ml-lex used function
3378 :     CharVector.foldli, taking advantage of its old interface.
3379 :     This has been replaced with the corresponding code from
3380 :     CharVectorSlice. (html-lex must be re-lexed!)
3381 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3382 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3383 :     8. Removed temporary additions (fromInternal, toInternal) from the
3384 :     (now obsolete) IntInf in smlnj-lib/Util.
3385 :     9. Cleaned up structure Byte.
3386 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3387 :     Cleaned/corrected implementation of Date.
3388 :     (Still need to check for correctness; implement better canonicalizeDate.)
3389 :     11. Added "scan" to signature IEEE_REAL.
3390 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3391 :     mod and rem when second operand is 2 (for parity checks).]
3392 :     13. Changed representation of type Time.time, using a single IntInf.int
3393 :     value counting microseconds. This considerably simplified the
3394 :     implementation of structure Time. We now support negative time
3395 :     values; scan and fromString handle signs.
3396 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3397 :     ArraySlice).

3402 :     Tag: blume-20030828-intinf
3403 :     Description:
3404 :    
3405 :     This is a major update which comes with a version number bump
3406 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3407 :     and an implementation of IntInf in the Basis.
3408 :    
3409 :     There are a fairly large number of related changes and updates throughout
3410 :     the system:
3411 :    
3412 :     Basis:
3413 :     - Implemented IntInf.
3414 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3415 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3416 : mblume 1347 - Added FixedInt as a synonym for Int32.
3417 :    
3418 :     compiler:
3419 :     * Added support for a built-in intinf type.
3420 :     - literals
3421 :     - pattern matching
3422 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3423 :     - overloading on literals and operations
3424 :    
3425 :     This required adding a primitive type intinf, some additional
3426 :     primops, and implementations for several non-trivial intinf
3427 :     operations in Core. (The intinf type is completely abstract
3428 :     to the compiler; all operations get delegated back to the Core.)
3429 :    
3430 :     * Intinf equality is handled by polyequal. However, the compiler
3431 :     does not print its usual warning in this case (since polyequal
3432 :     is the right thing to do there).
3433 :    
3434 :     * Improved the organization of structure InlineT.
3435 :    
3436 :     * A word about conversion primops:
3437 :     If conversions involving intinf do not cancel out during
3438 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3439 : mblume 1347 Since all core access must be resolved already during the FLINT
3440 :     translate phase, it would be too late a the time of CPS contract
3441 : mblume 1348 to add new Core calls. For this reason, conversion primops
3442 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3443 :     they are supposed to convert, and 2. the Core function that
3444 :     can help with this conversion if necessary. If CPS contract
3445 : mblume 1348 eliminates a primop, then the associated Core function becomes
3446 :     dead and goes away. Intinf conversion primops that do not get
3447 :     eliminated by CPS contract get rewritten into calls of their
3448 :     core functions by a separate, new phase.
3449 : mblume 1347
3450 :     interactive system:
3451 :     - Control.Print.intinfDepth controls max length of intinf constants
3452 :     being printed. (Analogous to Control.Print.stringDepth.)
3453 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3454 :     duplicates; replaced some of the code with code that makes better
3455 :     use of library functionality.
3456 :    
3457 :     CM:
3458 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3459 :     are no longer silent.
3460 :    
3461 :     CKIT:
3462 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3463 :     in favor of LargeInt -- which is now the same as IntInf.
3464 :     CKIT-knowledgable people should check whether this is what's
3465 :     intended and otherwise change things back to using Int32 or
3466 :     FixedInt.
3467 :    
3468 :     Throughout the code:
3469 : mblume 1348 Started using IntInf.int literals and built-in operations
3470 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3488 : mblume 1342 Date: 2003/08/11 15:45:00 CDT
3489 :     Tag: blume-20030811-windows
3490 :     Description:
3491 :    
3492 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3493 :    
3494 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3495 :    
3496 :     This patch restores SML/NJ's ability to run under win32. There are a
3497 :     number of changes, including fixes for several bugs that had gone
3498 :     unnoticed until now:
3499 :    
3500 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3501 :     trying to run the win32 version from within cygwin.)
3502 :    
3503 :     - There are a number of simple .bat scripts that substitute for their
3504 :     corresponding Unix shell-scripts. (See below.)
3505 :    
3506 :     - The internals of ml-build have been modified slightly. The main
3507 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3508 :     using OS.Process.system, the ML process delegates this task back
3509 :     to the script. Otherwise problems arise in mixed environments such
3510 :     as Cygwin where scripts look and work like Unix scripts, but
3511 :     where OS.Process.system cannot run them.
3512 :    
3513 :     - In CM, the srcpath pickler used native pathname syntax -- which
3514 :     is incorrect in the case of cross-compilation. The new pickle format
3515 :     is independent of platform-specific naming conventions.
3516 :    
3517 :     - Path configuration files (such as lib/pathconfig) can now choose
3518 :     between native and standard syntax. Placing a line of the form
3519 :    
3520 :     standard!
3521 :    
3522 :     into the file causes all subsequent paths to be interpreted using
3523 :     CM standard pathname syntax (= Unix conventions); a line
3524 :    
3525 :     native!
3526 :    
3527 :     switches back to native style. This was needed so that
3528 :     path config files can be written portably, see src/system/pathconfig.
3529 :    
3530 :     - Runtime system:
3531 :    
3532 :     - win32-filesys.c: get_file_time and set_file_time now
3533 :     access modification time, not creation time.
3534 :    
3535 :     - I/O code made aware of new array representation.
3536 :    
3537 :     - Bug fixes in X86.prim.masm.
3538 :    
3539 :     - src/system/makeml made aware of win32. (For use under cygwin
3540 :     and other Unix-environments for windows.)
3541 :    
3542 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3543 :     which caused BinIO.inputAll to fail consistently.
3544 :    
3545 :     .bat scripts:
3546 :    
3547 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3548 :    
3549 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3550 :     applications (sml, ml-yacc, ml-lex).
3551 :     - ml-build.bat: analogous to ml-build.
3552 :     - config\install.bat: Analogous to config/install.sh. This requires
3553 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3554 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3555 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3556 :     and the bootfile hierarchy must have been unpacked under
3557 :     sml.boot.x86-win32.
3558 :     The script is very primitive and does a poor job at error checking.
3559 :     It only installs the base system, ml-lex, and ml-yacc. No other
3560 :     libraries are being installed (i.e., you get only those that
3561 :     are part of the compiler.)
3562 :     - link-sml.bat: analogous to .link-sml, but not currently used
3563 :    
3564 :     Unrelated bug fixes:
3565 :    
3566 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3567 :     types.
3568 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3569 :     otherwise.)

3594 :    
3595 :     Two changes:

3598 :     be treated as errors (default is false).
3599 :     2. Cleaned up the *entire* source tree so that CMB.make goes through

3606 :     Description:
3607 :    
3608 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3609 :    
3610 :     This mainly affects the quality of error messages. However, some
3611 :     of the code is now more straightforward than before. (Treatment of
3612 :     the above four constructs in translate.sml is much simpler than
3613 :     the "macro-expansion" that was going on before. Plus, the mach-
3614 :     compiler no longer gets invoked just to be able to compile an
3615 :     if-expression.)
3616 :    
3617 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3618 :     interactive loop.

3636 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3637 :    
3638 :     This is only needed for bootstrapping the cygwin version of smlnj.

3677 :     Description:
3678 :    
3679 :     Added a call of SrcPath.sync at the beginning of Parse.parse (in CM).
3680 :     This fixes the problem of CM getting confused by files that suddenly
3681 :     change their identity (e.g., by getting unlinked and recreated by some
3682 :     text editor such as vi). There might be a better/cheaper/cleaner way
3683 :     of doing this, but for now this will have to do.

3697 :     Description:
3698 :    
3699 : blume 1282 In good old tradition, there has been a slight hiccup so that we have
3700 :     to patch 110.42 after the fact. The old release tag has been replaced
3701 :     (see below).
3702 :    
3703 :     The change solves a problem with two competing approaches the
3704 :     configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
3705 :     each other's way.
3706 :    
3707 :     This change only affects the runtime system code and the installer script.
3708 :     (No new bootfiles.)

3725 :     the PPC because the hardware indicates divide-by-zero using "overflow" as
3726 :     well.

3732 :     Description:
3733 :    
3734 :     Sml now senses the SMLNJ_HOME environment variable. If this is set,
3735 :     then the bin dir is assumed to be in $SMLNJ_HOME/bin and (unless
3736 :     CM_PATHCONFIG is also set), the path configuration file is assumed
3737 :     to be in $SMLNJ_HOME/lib/pathconfig. This way one can easily move
3738 :     the entire tree to some other place and everything will "just work".
3739 :    
3740 :     (Companion commands such as ml-build and ml-makedepend also sense this
3741 :     variable.)

3774 :     Fixed a bug in translation of INLMAX (and INLMIN) for the floating-point
3775 :     case. (The sense of the isNaN test was reversed -- which made min and
3776 :     max always return their first argument.)

3792 :     I back-ported my implementation of IEEEReal.fromString from the
3793 :     idlbasis-devel branch so that we can test it.
3794 :    
3795 :     Another small change is that ppDec tries to give more information
3796 :     than just "<sig>" in the case of functors. However, this code is
3797 :     broken in some mysterious way if the functor's body's signature
3798 :     has not been declared by ascription but gets inferred from the
3799 :     implementation. This needs fixing...

3862 :    
3863 :     - Added ControlUtil structure to control-lib.cm.

3865 :     - Used Controls facility to define MLRISC controls (as opposed to
3866 :     registering MLRISC control ref cells with Controls after the fact)
3867 :     - Fixed messed-up controls priorities.
3868 :    
3869 :     * Removed again all the stuff from config/preloads that one wouldn't
3870 :     be able to preload at the time the initial heap image is built.
3871 :     (Many libraries, e.g., CML, do not exist yet at this time. The
3872 :     only libraries that can be preloaded via config/preloads are those
3873 :     that come bundled with the bootfiles.)

3898 :     Description:
3899 :    
3900 :     0. John Reppy made several modifications to the SML/NJ library.
3901 :     In particular, there is a shiny new controls-lib.cm.
3902 :    
3903 :     1. Pushed new controls interface through compiler so that everything
3904 :     compiles again.
3905 :    
3906 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3907 :     SML/NJ library (so that CML compiles again).
3908 :    
3909 :     3. Modified init scripts because XXX_DEFAULT environment variables
3910 :     are no longer with us. (Boot-time initialization is now done
3911 :     using the same environment variables that are also used for
3912 :     startup-time initialization of controls.)

3917 :     Tag: george-20020515-pseudo-op-decls
3918 :     Description:
3919 :    
3920 :     All pseudo-ops emitted before the first segment declaration
3921 :     such as TEXT, DATA, and BSS directives are assumed to be global
3922 :     declarations and are emitted first in the assembly file. This is
3923 :     useful in a number of situations where one has pseudo-ops that are not
3924 :     specific to any segment, and also works around the constraint that one
3925 :     cannot have client pseudo-ops in the TEXT segment.
3926 :    
3927 :     Because no segment is associated with these declarations it is
3928 :     an error to allocate any space or objects before the first segment
3929 :     directive and an exception will be raised. However, we cannot make
3930 :     this check for client pseudo-ops.
3931 :    
3932 :     These top level declarations are a field in the CFG graph_info.
3933 :     In theory you can continue to add to this field after the CFG has been
3934 :     built -- provided you know what you are doing;-)

3942 :     A few minor bugfixes:

3944 :     - Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
3945 :     (Bogus printouts for redefined bindings still occur. Compiler
3946 :     bug should no longer occur now. We need to redo the prettyprinter
3947 :     from scratch.)
3948 :

3950 :

3956 :     Tag: blume-20020510-erg-textio
3957 :     Description:
3958 :    
3959 :     Applied the following bugfix provided by Emden Gansner:
3960 :    
3961 :     Output is corrupted when outputSubstr is used rather than output.
3962 :    
3963 : blume 2155 The problem occurs when a substring
3964 : blume 1189
3965 :     ss = (s, dataStart, dataLen)
3966 :    
3967 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3968 :     avail bytes of s, starting at index dataStart, are copied into the
3969 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3970 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3971 :     starting this copy at index dataStart+avail in s, the current code
3972 : blume 1189 starts the copy at index avail.
3973 :    
3974 :     Fix:
3975 :     In text-io-fn.sml, change line 695 from
3976 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3977 : blume 2155 to
3978 : blume 1189 val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

3994 :     Description:
3995 :    
3996 :     Added full support for div/mod/rem/quot on the x86, using the machine
3997 :     instruction's two results (without clumsily recomputing the remainder)
3998 :     directly where appropriate.
3999 :    
4000 :     Some more extensive power-of-two support was added to the x86 instruction
4001 :     selector (avoiding expensive divs, mods, and muls where they can be
4002 :     replaced with cheaper shifts and masks). However, this sort of thing
4003 :     ought to be done earlier, e.g., within the CPS optimizer so that
4004 :     all architectures benefit from it.
4005 :    
4006 :     The compiler compiles to a fixed point, but changes might be somewhat
4007 :     fragile nevertheless. Please, report any strange things that you might
4008 :     see wrt. div/mod/quot/rem...

4014 :     Description:
4015 :    
4016 :     Fixed my broken div/mod logic. Unfortunately, this means that the
4017 :     inline code for div/mod now has one more comparison than before.
4018 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
4019 :     The problem was with quotient = 0, because that alone does not tell
4020 :     us which way the rounding went. One then has to look at whether
4021 :     remainder and divisor have the same sign... :(
4022 :

4030 :    
4031 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
4032 :    
4033 :     Primops have changed. This means that the bin/boot-file formats have
4034 :     changed as well.
4035 :    
4036 :     To make sure that there is no confusion, I made a new version.
4037 :    
4038 :    
4039 :     CHANGES:
4040 :    
4041 :     * removed REMT from mltree (remainder should never overflow).
4042 :    
4043 :     * added primops to deal with divisions of all flavors to the frontend
4044 :    
4045 :     * handled these primops all the way through so they map to their respective
4046 :     MLRISC support
4047 :    
4048 :     * used these primops in the implementation of Int, Int32, Word, Word32
4049 :    
4050 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
4051 :    
4052 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
4053 :    
4054 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
4055 :     floating point
4056 :    
4057 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
4058 :     and Real (but Real.abs maps to a separate floating-point-only primop)
4059 :    
4060 :    
4061 :     TODO items:
4062 :    
4063 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
4064 :     instructions because the machine instruction encoder cannot handle
4065 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
4066 :     REM in the first place, and REM is supported by the x86 machine coder.)
4067 :    
4068 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
4069 :     selection phase. (The two can be streamlined because the hardware
4070 :     delivers both quotient and remainder at the same time anyway.)
4071 :    
4072 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
4073 :     (Currently the behavior is inconsistent both across architectures and
4074 :     wrt. the draft Basis spec.)
4075 :    
4076 :     * Word8 should eventually be handled natively, too.
4077 :    
4078 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
4079 :     as if there currently is no execution path that could trigger it in
4080 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
4081 :     hold for things like multiplication and division.)

4088 :    
4089 :     Added support for all four division operations (ML's div, mod, quot,
4090 :     and rem) to MLRISC. In the course of doing so, I also rationalized
4091 :     the naming (no more annoying switch-around of DIV and QUOT), by

4093 :     DIV_TO_ZERO or DIV_TO_NEGINF).

4095 :     The generic MLTreeGen functor takes care of compiling all four
4096 :     operations down to only round-to-zero div.
4097 :    
4098 :     Missing pieces:
4099 :    
4100 :     * Doing something smarter than relying on MLTreeGen on architectures
4101 :     like, e.g., the x86 where hardware division delivers both quotient and
4102 :     remainder at the same time. With this, the implementation of the
4103 :     round-to-neginf operations could be further streamlined.
4104 :    
4105 :     * Remove inlining support for div/mod/rem from the frontend and replace it
4106 :     with primops that get carried through to the backend. Do this for all
4107 :     int and word types.

4113 :     Description:
4114 :    
4115 :     I improved (hopefully without breaking them) the implementation of Int.div,
4116 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
4117 :     advantage of the following observations:
4118 :    
4119 :     Let q = x quot y r = x rem y
4120 :     d = x div y m = x mod y
4121 :    
4122 :     where "quot" is the round-to-zero version of integer division that
4123 :     hardware usually provides. Then we have:
4124 :    
4125 :     r = x - q * y where neither the * nor the - will overflow
4126 :     d = if q >= 0 orelse x = q * y then q else q - 1
4127 :     where neither the * nor the - will overflow
4128 :     m = if q >= 0 orelse r = 0 then r else r + y
4129 :     where the + will not overflow
4130 :    
4131 :     This results in substantial simplification of the generated code.
4132 :     The following table shows the number of CFG nodes and edges generated
4133 :     for
4134 :     fun f (x, y) = x OPER y
4135 :     (* with OPER \in div, mod, quot, rem *)
4136 :    
4137 :    
4138 :     OPER | nodes(old) | edges(old) | nodes(new) | edges(new)
4139 :     --------------------------------------------------------
4140 :     div | 24 | 39 | 12 | 16
4141 :     mod | 41 | 71 | 12 | 16
4142 :     quot | 8 | 10 | 8 | 10
4143 :     rem | 10 | 14 | 8 | 10
