536 :     Description:

538 :     3rd merge of base from primop-branch-3 into the trunk.
539 :     Additional bug fixes included:
540 :    
541 :     * Timer.cpu_timer, etc. type printing corrected (by making

548 :     Date: 2007/05/31 11:40:00 CDT
549 :     Description:
550 :    
551 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
552 :    
553 :     Also, changed the handling of "no core access": When translate.sml
554 :     needs access to a core exception at a time when the core has not
555 :     been set up yet (this only happens when compiling system/smlnj/init/*),
556 :     then don't bother generating the corresponding tests.
557 :    
558 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
559 :     the exception. Unfortunately, that confuses the plambda type checker.
560 :     Moreover, it does not do any good, because at runtime we don't expect
561 :     such an exception to be ever raised. (The code in system/smlnj/init/*
562 :     has to be written very carefully with this in mind!)

574 :     Description:
575 :    
576 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
577 :     with an explicit test for zero division. This should fixes several
578 :     regressions and makes it possible for downstream optimization phases
579 :     to treat these operations as "pure" when they are applied to unsigned
580 :     operands.

595 :    
596 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes

602 :     Date: 2007/05/23 22:30:00 CDT
603 :     Description:
604 :    
605 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
606 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
607 :    
608 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
609 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
610 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
611 :     while running CMB.make. The point is that the single symbol
612 :     NO_PLUGINS is definde in all three cases.)
613 :    
614 :     I changed the three locations within the sources that get compiled
615 :     during CMB.make where ml-yacc or ml-lex input is processed: When
616 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
617 :     is bypassed.
618 :    
619 :     When bootstrapping new versions of the compiler, there can be
620 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
621 :     are not available or otherwise not operational. In this case one can
622 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
623 :     do so, the following command should be issued at the interactive
624 :     prompt:
625 :    
626 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
627 :    
628 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
629 :     files that normally would be generated by ml-yacc and ml-lex.
630 :     (Copies of these files are in the repository.)

646 :     Description:
647 :    
648 :     Changed the installation mechanism for CM tool plugins. These are
649 :     just libaries and now get installed like ordinary libaries.
650 :    
651 :     There are now a number of new installation targets that give some
652 :     fine-grain control over what classes and suffixes are known, and what
653 :     they will map to.
654 :     See config/targets for details.
655 :    
656 :     The code that caused plugin installation as part of running a
657 :     tool's "build" script has been removed. (The build script is for
658 :     building, not for installing.)

663 :     Description:
664 :    
665 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
666 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
667 :     CM fail if a shell tool reports a non-success exit status. If
668 :     the control is set to true, then CM will press on after tool failures
669 :     in the event that the target files exist (even though they are
670 :     considered outdated). Turning the control to true can be useful for
671 :     bootstrapping.

676 :     Description:
677 :    
678 :     Merge of ml-lpt revisions for 110.64.
679 :    
680 :     The name of several ml-lpt-lib modules has changed:
681 :     Repair => AntlrRepair
682 :     StreamPos => AntlrStreamPos
683 :     ErrHandlerFn => AntlrErrHandler
684 :     EBNF => AntlrEBNF
685 :    
686 :     The ml-antlr specification format has changed: declarations such as
687 :     %tokens and nonterminal definitions can occur *multiple* times in the
688 :     same specification. The semantics are such that each new declaration
689 :     extends the previous ones. This does not apply to %start or %name,
690 :     of course.
691 :    
692 :     Importing a grammar via %import now includes *all* declarations in from
693 :     the imported grammar, except for %name, %entry, and %start. Tokens
694 :     and nonterminals can be dropped using the new %dropping clause of the
695 :     %import directive; the separate %drop and %extend have been removed.
696 :    
697 :     We now allow optional type annotations on nonterminals, using the %nonterms
698 :     directive as in ml-yacc.
699 :    
700 :     The refcell construct is now implemented using SML's regular reference
701 :     cells, so the :== and !! notation has been deprecated.
702 :    
703 :     The ml-antlr tool now does much more checking of specifications, and
704 :     its error messages have been greatly improved. Error repair for
705 :     generated parsers has been completely rewritten, and is now both
706 :     much faster and more accurate.
707 :    
708 :     ml-ulex is now more lenient with escape codes (non-SML-standard
709 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
710 :     Also, character classes may now include a "-" character at the beginning
711 :     as is standard in most other regexp tools.
712 :    
713 :     All of these changes are documented in the user guide, which has
714 :     been updated and improved with this merge.

720 :     Description:
721 :    
722 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
723 :     Significant changes in FLINT and the front end, mostly having to do
724 :     with a reorganized system for handling primops. Various bug fixes
725 :     and improvements in printing signatures.

730 :     Description:
731 :    
732 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
733 :     The ml-antlr specification format has changed: declarations such as
734 :     %tokens and nonterminal definitions can occur *multiple* times in the
735 :     same specification. The semantics are such that each new declaration
736 :     extends the previous ones. Grammar extension constructs have also
737 :     changed. We now allow type annotations on nonterminals. Finally,
738 :     the refcell construct is now implemented using SML's regular reference
739 :     cells, so the :== and !! notation has been deprecated. All of these
740 :     changes will appear in the 110.64 user guide for ml-lpt.
741 :    
742 :     The ml-antlr tool now does much more checking of specifications, and
743 :     its error messages have been greatly improved. There has also been
744 :     some work on the error repair process for generated parsers, but this
745 :     will be further improved in 110.64.

751 :    
752 :     More Basis fixes: The Char.fromString (etc.) functions did not handle

839 :     Initially, we plan to use this code to generate C calls for the AMD64.

906 :     Date: 2007/01/31
907 :     Description:
908 :    
909 :     Brought ml-lpt manual up-to-date with the code. Many minor
910 :     improvements to the tools, and a few minor bugfixes. Prepared
911 :     ml-lpt-lib for integration with new UTF8 structure. Changed
912 :     the interface for creating streams in ml-ulex (we now support
913 :     stream creation from several kinds of sources). Overall, the
914 :     tools are now quite stable, and their interfaces are unlikely to
915 :     change in a way that would break compatibility. More work,
916 :     however, is needed in the documentation.

921 :     Description:
922 :    
923 :     Implemented library installer. Moved CM plugin code for
924 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
925 :     their respective trees. Implemented CM plugin for ml-ulex
926 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
927 :     and ml-antlr.
928 :    
929 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
930 :     CM tools. (It turns out to be too messy to do otherwise because
931 :     there is too much code that during installation relies on the presence
932 :     of these tools -- resulting in a tricky ordering problem.)

937 :     Description:
938 :    
939 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
940 :     Modified CM's startup code to use shiftArgs as it processes
941 :     command line arguments. This way, the init code in each .sml-file
942 :     or library that is mentioned at the top level will see only
943 :     those arguments that have not yet been processed at this point.
944 :     In other words, the init code can "seize control" and process the
945 :     remaining command line.

1012 :     Description:
1013 :    
1014 :     Added code to CM's "standard shell tool" implementation which
1015 :     causes it to tolerate (with a warning) the situation where the shell
1016 :     command fails (e.g., due to the shell command's non-existence)
1017 :     as long as all target files exist.
1018 :    
1019 :     This makes it possible to, e.g., build ml-yacc from sources even if
1020 :     svn checkout messed up the time stamps on files in such a way that
1021 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
1022 :     be needed to re-process yacc.grm, but obviously it might not yet be
1023 :     available at that time.)

1029 :    
1030 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
1031 :     recvVecFromNB' in the SOCKET signature. This error is actually
1032 :     in the SML Basis specification too.

1062 :     Tag: release-110.60
1063 :     Description:
1064 :    
1065 :     New working release (110.60). NEW BOOTFILES!
1066 :    
1067 :     This is the first subversion-hosted release. There are also changes
1068 :     to the directory layout. Here is a table:
1069 :    
1070 :     (All pathnames are relative to the SML/NJ "root" directory.)
1071 :    
1072 :     config -> config
1073 :    
1074 :     src/cm -> base/cm
1075 :     src/compiler -> base/compiler
1076 :     src/runtime -> base/runtime
1077 :     src/system -> base/system
1078 :    
1079 :     src/cm/pgraph -> pgraph
1080 :    
1081 :     src/READMES -> base/READMES
1082 :     src/$notefile -> base/NOTES/$notefile
1083 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1084 :     MACOSXINSTALL WININSTALL
1085 :    
1086 :     src/smlnj-lib -> smlnj-lib
1087 :     src/MLRISC -> MLRISC
1088 :     ckit -> ckit
1089 :     src/cml -> cml
1090 :     src/eXene -> eXene
1091 :     src/heap2asm -> heap2asm
1092 :     src/lexgen -> lexgen
1093 :     src/ml-burg -> ml-burg
1094 :     src/ml-lex -> ml-lex
1095 :     src/ml-yacc -> ml-yacc
1096 :     src/ml-nlffi-lib -> nlffi/lib
1097 :     src/ml-nlffigen -> nlffi/gen
1098 :     src/smlnj-c -> smlnj-c
1099 :     src/tools/TraceDebugProf -> trace-debug-profile
1100 :    
1101 :     In addition, there is also a new
1102 :    
1103 :     ml-lpt
1104 :    
1105 :     directory containing two new program generator tools: ml-ulex and
1106 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1107 :     LL(k) parser generator). These tools are currently "beta-quality"
1108 :    
1109 :     The latest versios of the sources can now be obtained anonymously
1110 :     via subversion. For this, it is useful to first check out
1111 :    
1112 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1113 :    
1114 :     and put the resulting directory on your shell's PATH. This provides
1115 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
1116 :     and refresh-all.sh.
1117 :    
1118 :     To create a freshly checked-out copy of the sources, do
1119 :    
1120 :     checkout-all.sh [dir]
1121 :    
1122 :     where dir is the optional SML/NJ root directory (default is ".").
1123 :    
1124 :     This creates the above directory layout. Each subdirectory of
1125 :     the root is under individual subversion control. The stat-all.sh
1126 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
1127 :     each of these subtrees.
1128 :

1130 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
1131 : blume 2155 Date: 2006/11/02 12:20:00 CST
1132 :     Description:
1133 :    
1134 :     Reorganized directory layout.
1135 :    
1136 :     This is a temporary solution, more reorganization is to come.
1137 :    
1138 :     The basic idea is to have a number of toplevel trees, each corresponding
1139 :     to a well-defined part of the overall system. Each part can be
1140 :     maintained individually, even in separate source repositories,
1141 :     although currently we still serve everything out of the main
1142 :     smlnj-gforge tree.
1143 :    
1144 :     Installer and and scripts have been updated to reflect the new
1145 :     layout. The installer (base/src/system/smlnj/installer) is now
1146 :     "scriptable" to avoid burning too much knowledge about the
1147 :     layout into SML source code. The main script used by the installer
1148 :     is in config/actions.
1149 :    
1150 :     The main change is that many of the subdirectories of what used to
1151 :     be known as "src" have moved to the toplevel. The "src" directory
1152 :     itself has moved down into a subtree called "base". (We may eventually
1153 :     get rid of the extra level of indirection represented by "src".)
1154 :    
1155 :     The layout is now as follows:
1156 :    
1157 :     toplevel tree name | default repository
1158 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1159 :     -------------------+----------------------------------------------------
1160 :     config | $gf/config/trunk
1161 :     |
1162 :     base | $gf/sml/trunk
1163 :     |
1164 :     smlnj-lib | $gf/smlnj-lib/trunk
1165 :     MLRISC | $gf/MLRISC/trunk
1166 :     |
1167 :     ml-yacc | $gf/ml-yacc/trunk
1168 :     ml-lex | $gf/ml-lex/trunk
1169 :     ml-burg | $gf/ml-burg/trunk
1170 :     lexgen | $gf/lexgen/trunk
1171 :     heap2asm | $gf/heap2asm/trunk
1172 :     |
1173 :     cml | $gf/cml/trunk
1174 :     eXene | $gf/eXene/trunk
1175 :     ckit | $gf/ckit/trunk
1176 :     nlffi | $gf/nlffi/trunk
1177 :     |
1178 :     smlnj-c | $gf/smlnj-c/trunk
1179 :    
1180 :     In $gf/admin there are a few useful shell scripts for checking out
1181 :     and maintaining the entire collection of trees:
1182 :    
1183 :     admin/checkout-all.sh [dir]
1184 :     -- optionally creates dir and checks out all trees from their
1185 :     default repositories; if dir is missing, checkout into .
1186 :     admin/refresh-all.sh [dir]
1187 :     -- looks at all trees (from the above list) in dir (default: .)
1188 :     and runs "svn update" if the tree exists and is under
1189 :     subversion control;
1190 :     non-existing or non-subversion trees are skipped
1191 :     admin/stat-all.sh [dir]
1192 :     -- like refresh-all.sh, but runs "svn stat" instead

1338 :     Description:
1339 :    
1340 :     Hooked code for Darwin-specific Intel ABI into main compiler.
1341 :     (This is a temporary solution which relies on the fact that the
1342 :     compiler itself does not use NLFFI. Eventually we need to divorce
1343 :     intel mac from generic x86 unix code and make separate sets of binaries.)

1372 :     Description:
1373 :    
1374 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1375 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1376 : blume 2155 at the time when config/preloads is processed, the library has to
1377 : mblume 1878 be referred to by another name. In 110.57 this would be
1378 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1379 :     to be valid as well.)

1434 :     Tag: blume-22051115-versiontool
1435 :     Description:
1436 :    
1437 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1438 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1439 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1440 :     it. Instead, it has the status of "user code", so it should use
1441 :     $/basis.cm to refer to the Basis library. (At least that's true for
1442 :     the purpose of bootstrapping the previous change. In the future it
1443 :     might make sense to have versiontool.cm refer to
1444 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1445 :     compiler itself uses.)
1446 :    
1447 :     Also patched src/system/testml to have it activate those extra anchor
1448 :     bindings in config/extrapathconfig.

1453 :     Tag: blume-22051115-libraries
1454 :     Description:
1455 :    
1456 :     This change affects the way the following libraries are tied into
1457 :     the system:
1458 :    
1459 :     $/basis.cm
1460 :     $/smlnj-lib.cm
1461 :     $/pp-lib.cm
1462 :     $/controls-lib.cm
1463 :     $/html-lib.cm
1464 :     $/ml-yacc-lib.cm
1465 :    
1466 :     These libraries are now internally (as seen from the source code
1467 :     of the implementation itself) known by the following names:
1468 :    
1469 :     $smlnj/basis/basis.cm
1470 :     $smlnj/smlnj-lib/smlnj-lib.cm
1471 :     $smlnj/smlnj-lib/pp-lib.cm
1472 :     $smlnj/smlnj-lib/controls-lib.cm
1473 :     $smlnj/smlnj-lib/html-lib.cm
1474 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1475 :    
1476 :     This makes it possible to work with code that requires different
1477 :     versions of these libraries, and which refers to these libraries using
1478 :     their "default" names (i.e., the first set of names above). In other
1479 :     words, one can un-define or re-define those default names without
1480 :     compromising the proper functioning of the compiler itself.
1481 :    
1482 :     A similar procedure had already been performed for several of the
1483 :     MLRISC libraries that are linked into the compiler. I did some
1484 :     cleanup on this code.
1485 :    
1486 :     A new file in the config directory (named extrapathconfig) is
1487 :     responsible for setting up path anchors that the compiler itself does
1488 :     not need, but that are typically required by user code.

1668 :     Description:
1669 :    
1670 :     Added mechanism for re-creating a heap file for the interactive system
1671 :     after configuration variables have been changed.
1672 :    
1673 :     CM.redump_heap : string -> unit
1674 :    
1675 :     This is much like SMLofNJ.exportML, but starting from the resulting
1676 : blume 2155 heap does not return to the caller of CM.redump_heap but
1677 : mblume 1792 restarts the interactive system from scratch. The original call of
1678 :     CM.redump_heap does not return but ends the interactive session.
1679 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1680 :    
1681 :     Internally, redump_heap winds the dynamic execution context back to
1682 :     the point where the original heap image was created and re-executes
1683 :     the heap image generation code in the boot code.

1800 :     Description:
1801 :    
1802 :     Implemented new (but still experimental) heap2exec facility. This is
1803 :     tested under Mac OS X and should work under Linux (will test shortly).
1804 :     It will probably also work on the Sparc (will test some time later).
1805 :    
1806 :     - removed old "HACKED_STANDALONE" hack from runtime
1807 :    
1808 :     To be able to test this, uncomment the request for "heap2asm" in
1809 :     config/targets prior to installation. (Notice that this is different
1810 :     from "heap2exec" mentioned below. Not a typo.)
1811 :    
1812 :     To perform an actual test, run the command
1813 :    
1814 :     $ bin/heap2exec heapfile execfile
1815 :    
1816 :     (You can put heap2exec on your shell's path.)
1817 :    
1818 :     For example, run
1819 :    
1820 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1821 :    
1822 :     This will create a standalone executable called "mly" which you can
1823 :     then invoke directly as a command.

1849 :     data structure access seems to work.)
1850 :    
1851 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1852 :     (On the Mac, it is big-endian. And that's currently our only
1853 :     PPC platform.)

1968 :     Tag: blume-20041124-position
1969 :     Description:
1970 :    
1971 :     The compiler can now be compiled in a mode that makes structure Position
1972 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1973 :     for the time being.
1974 :    
1975 :     To enable 64-bit positions, use the following procedure:
1976 :    
1977 :     1. Start sml
1978 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1979 :     3. Type
1980 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1981 :     4. Run CMB.make() as usual.
1982 :    
1983 :     This is barely tested. The only test so far was a little SML program
1984 :     counting the number of characters in an 8-gigabyte file by
1985 :     reading it character-by-character. That test was successful.
1986 :    
1987 :     In support of 64-bit positions, a number of new functions have been
1988 :     added to the runtime system.

2032 :     The date string is generated at bootstrap time (during makeml).
2033 :    
2034 :     - In a previous commit, fixed a minor issue with how polyequal is being
2035 :     translated. In particular, the code now "looks through" abstractions.
2036 :     This results in slightly fewer polyEqual warnings and hopefully slightly
2037 :     more efficient code. Important examples for where this matters are
2038 :     the new int64 and word64 types.

2053 :     Description:
2054 :    
2055 :     All the pieces of Word64 are now there, with the exception of the
2056 :     conversions from and to LargeWord. (Eventually these need to be identities,
2057 :     but for the time being they don't even make sense because LargeWord is
2058 :     32-bit wide.)
2059 :    
2060 :     Also started to add similar support for Int64, but major pieces of that
2061 :     are still missing.

2067 :     Description:
2068 :    
2069 :     Structure Word64 is now (almost) complete, word literals and patterns
2070 :     seem to work. There are a few odd pieces missing. In particular,
2071 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2072 :     at the moment.
2073 :    
2074 :     Making Word64 official would mean that LargeWord becomes Word64. But
2075 :     this requires extreme care because most word-word conversions have to
2076 :     go through LargeWord, so making a mistake means loss of efficiency or
2077 :     worse. Eventually there will be a solution similar to (but actually
2078 :     simpler than) what I did with IntInf.

2093 : mblume 1682 Description:
2094 :    
2095 :     Started adding some infrastructure for supporting 64-bit int- and

2102 :     Description:
2103 :    
2104 :     New working version (110.50). NEW BOOTFILES!
2105 :    
2106 :     =====================
2107 :    
2108 :     Also:
2109 :    
2110 :     - Changend config/srcarchiveurl from a file just
2111 :     containing the URL string into a file containing
2112 :     shell script code. The code has access to the $VERSION variable.
2113 :     - Made corresponding changes to config/install.sh and config/unpack.
2114 :     - Default contents of config/srcarchiveurl uses $VERSION and
2115 :     normally does not have to be edited to reflect a version change.
2116 :    
2117 :     (As a result, a version change can be done by just editing
2118 :     config/version, the rest is now automatic.)

2135 :     This is the HISTORY entry for two earlier commits, both concerning
2136 :     the x86 c-calls code in MLRISC:
2137 :    
2138 :     - added a missing LOAD in the code that deals with struct arguments
2139 :     - made sure the caller does not add the wrong number of bytes to the
2140 :     stack pointer after a call of a function returning a struct
2141 :     (the callee already pops the implicit argument which points to
2142 :     the space reserved for the result)

2158 :     Tag: blume-20041020-standalone-backtrace
2159 :     Description:
2160 :    
2161 :     Added a mechanism for getting back-trace information from standalone
2162 :     programs. Here is how it works:
2163 :    
2164 :     1. The part of the program from which you want to get backtrace
2165 :     information (usually the whole program) should be wrapped with
2166 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
2167 :     main program could be modified from something like
2168 :    
2169 :     fun main (pgm, args) = ...
2170 :    
2171 :     to
2172 :    
2173 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2174 :    
2175 :     2. To be able to access BackTrace.monitor, you have to add
2176 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
2177 :     main function.
2178 :    
2179 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2180 :     CM might have created in the past for your project).
2181 :    
2182 :     4. Build the system using this command line:
2183 :    
2184 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2185 :     myprog.cm MyProg.main myprog
2186 :    
2187 :     instead of the usual
2188 :    
2189 :     ml-build myprog.cm MyProg.main myprog
2190 :    
2191 :     I changed a library name:
2192 :    
2193 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2194 :    
2195 :     New libraries:
2196 :    
2197 :     $smlnj-tdp/back-trace.cm
2198 :     -- when loaded causes the back-trace plugin to be installed
2199 :     $smlnj-tdp/coverage.cm
2200 :     -- when loaded causes the coverage plugin to be installed

2215 :     Tag: blume-20041015-coverage
2216 :     Description:
2217 :    
2218 :     * Test coverage tool added!
2219 :     * Further reorganization of tracing-, debugging-, and profiling support:
2220 :    
2221 :     - moved original BTImp -- now called BackTrace -- into a separate
2222 :     library called $/trace-debug-profile.cm
2223 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2224 :     - only the instrumentation mechanism is now left in the compiler proper
2225 :     - BackTrace module is a plugin which is NOT plugged in by default
2226 :     - Coverage module is another such plugin
2227 :    
2228 :     To get the benefits of any of these plugin modules, the code in
2229 :     question must be compiled with tdp instrumentation turned on. This
2230 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2231 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2232 :    
2233 :     Plugins are selected at link time. (Pre-compiled instrumented code
2234 :     can be re-loaded with different plugins in effect.) When an
2235 :     instrumented module is linked, whatever plugins are at that time
2236 :     enabled will come into effect for that module.
2237 :    
2238 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2239 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2240 :     To enable the coverage plugin, load the same library and invoke
2241 :     Coverage.install().
2242 :    
2243 :     Back-traces are generated automatically on uncaught exceptions and
2244 :     when the code in question explicitly invokes BackTrace.trigger().
2245 :    
2246 :     Coverage (and execution frequency-) information must be queried
2247 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2263 :    
2264 :     Some rationalization of names:
2265 :    
2266 :     structure BTrace -> structure TDPInstrument
2267 :     etc.
2268 :    
2269 :     This is is preparation of using the original back-trace
2270 :     instrumentation for other purposes. "TDP" stands for
2271 :     Trace/Debug/Profile.
2272 :    
2273 :     The control flag controlling whether instrumentation is on or off is now
2274 :     registered under a different name, so instead of running sml as
2275 :    
2276 :     sml -Cinstrument.btrace-mode=true
2277 :

2296 :     Description:
2297 :    
2298 :     Fixed handling of keywords in .cm files: After seeing "is" the lexer
2299 :     treats subsequent occurrences of "group", "library", "source", "is",
2300 :     "*", and "-" as ordinary identifiers rather than keywords.
2301 :    
2302 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool
2303 :     is supposed to accept a tool argument called "source", but this did
2304 :     not work because of the clash with the keyword.

2348 :    
2349 :     * Moved the "version" magic into its own little library under

2351 :     a stable src/compiler/core.cm.
2352 : mblume 1639
2353 : mblume 1672 * At the same time, structure CompilerVersion is now known as
2354 :     structure SMLNJVersion.
2355 : mblume 1639
2356 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2357 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2358 :     Also, loading the versiontool does not work when rebuilding the system
2359 :     because CM is not properly initialized at that time.

2364 :     Tag: blume-20040929-autoversion
2365 :     Description:
2366 :    
2367 :     Implemented some CM magic to have
2368 :     file src/compiler/TopLevel/main/version.sml
2369 :     generated automagically.
2370 :     The version is taken from two files: config/version and config/release.
2371 :     The first is expected to contain a two-part version number such as 110.49.
2372 :     The second should contain a single number, but it may be missing.
2373 :    
2374 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2375 :     time the version tool is loaded (which is the first time you say CMB.make),
2376 :     then the tool will increment the value stored in config/release every
2377 :     time CMB.make is invoked.
2378 :    
2379 :     The binfile format is now insensitive to anything beyond the first
2380 :     two components of a version number, so bumping the release does not render
2381 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2382 :     during development without invalidating existing binfiles.
2383 :    
2384 :     In any case, every CMB.make updates the date information in version.sml.
2385 :     (This is the date that is printed in the banner.)

2398 :     Tag: blume-20040927-controls
2399 :     Description:
2400 :    
2401 :     Added two pieces of functionality to the Controls interface:
2402 :    
2403 :     1. val save'restore: 'a control -> unit -> unit
2404 :    
2405 :     grabs the current value of the control in stage 1 and restores it
2406 :     in stage 2.
2407 :    
2408 :     2. val set' : 'a control * 'a -> unit -> unit
2409 :    
2410 :     stores the given value into the control in stage 2 (i.e., delayed)
2411 :     but does all error checking in stage 1.
2412 :     (This is for string controls that need to do parse their argument --
2413 :     something that might fail. In some cases, notably in CM, one
2414 :     already knows the intended argument but wants to delay the actual
2415 :     assignment until a time when error recovery would be more difficult.)
2416 :    
2417 :     Changed the handling of controls in tool arguments to classes "sml" and
2418 :     "lazysml":
2419 :     - use Controls.save'restore as a more robust way of restoring the
2420 :     old value (in particular: without having to re-parse the string)
2421 :     - use controls to handle the "overload" keyword in the init group
2422 :     (I believe this change actually fixes a long-standing obscure bug.)

2427 :     Tag: blume-20040927-lazysml
2428 :     Description:
2429 :    
2430 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2431 :     difference to "sml" is that compilation is done with Control.lazysml
2432 :     set to true. A source of class "lazysml" is automatically recognized
2433 :     by a file name suffix of ".lml".
2434 :    
2435 :     In addition to the above feature, the original class "sml" now also
2436 :     supports a tool argument "lazy" which has the same effect. As a
2437 :     result, the following three lines are equivalent:
2438 :    
2439 :     foo.sml : lazysml
2440 :     foo.sml : sml (lazy)
2441 :     foo.sml (lazy)
2442 :    
2443 :     The setting goes into effect both during parsing and during
2444 :     compilation. The original setting is restored right after parsing and
2445 :     after compilation, respectively.
2446 :    
2447 :     In addition to all the above, there is also a general mechanism to set
2448 :     ANY of the "controls" that are available at the command line via
2449 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2450 :     apply as well. (In fact, "lazy" is implemented as a special case of
2451 :     the general mechanism.)
2452 :    
2453 :     The .cm file syntax uses a new keyword tool argument called "with".
2454 :     There are several ways of indicating the desired settings:
2455 :    
2456 :     foo.sml (with:parser.quotations=true)
2457 :     foo.sml (with:(name:parser.quotations value:true))
2458 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2459 :     foo.sml (with:(name1=value1 name2=value2 ...))
2460 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2461 :    
2462 :     etc.
2463 :    
2464 :     Another possible abbreviation is to leave out the =v or value:v part
2465 :     if the name refers to a boolean control (in which case the value is
2466 :     taken to be true). Thus, one could get lazy sml also by saying:
2467 :    
2468 :     foo.sml (with:parser.lazy-keyword=true)
2469 :     foo.sml (with:parser.lazy-keyword)
2470 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2471 :     foo.sml (with:(name:parser.lazy-keyword))

2823 :     Description:
2824 :    
2825 :     Changed the interface of structures Timer and Unix to match the most
2826 :     recent Basis spec.
2827 :    
2828 :     In the case of Unix there still seems to be an open/weird issue:
2829 :    
2830 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2831 :     fresh streams whenever they are called -- as opposed to have them
2832 :     return the same stream every time. This design is supposed to
2833 :     prevent space leaks caused by proc values hanging on to streams.
2834 :    
2835 :     The reap function, on the other hand, is supposed to close the
2836 :     streams. This cannot be done without having a handle on the
2837 :     stream in proc after all...
2838 :    
2839 :     I took the liberty to implement the following stopgap solution:
2840 :    
2841 :     The proc value hangs on to the most recently created stream(s).
2842 :     Reap closes those. If either or both of the two streams hadn't
2843 :     been created at all yet, then reap will close the corresponding
2844 :     file descriptors directly.
2845 :    
2846 :     PS: I don't understand the original space leak argument anymore. If
2847 :     a proc hangs on to the imperative stream, then I/O operations on those
2848 :     will advance the state of the cached stream and avoid the space leak.

2861 :     Tag: blume-20040525-group-owner
2862 :     Description:
2863 :    
2864 :     CM now ignores (but still accepts) the "owner" information in group
2865 :     descriptions. The owner of a group is its next enclosing
2866 :     library. Each group must have a unique owner. (There is a virtual
2867 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2868 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2869 :     and CM would check that such a declaration is correct. The new scheme
2870 :     is to have CM check that for each group there is precisely one owning
2871 :     library.
2872 :    
2873 :     The advantage of the new scheme is that the programmer no longer needs
2874 :     to maintain the somewhat annoying owner information. The downside is
2875 :     that CM cannot enforce the ownership rule across multiple runs of
2876 :     CM.make. Fortunately, enclosing the same group in two different
2877 :     libraries A and B which are not part of the same program does not
2878 :     cause real problems.

2897 :     Description:
2898 :    
2899 :     Arranged for ml-build to clean up after itself a little bit better.
2900 :     The script generates a temporary SML source file and compiles it using
2901 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
2902 :     gets rid of those at the end, so they don't accumulate under .cm.
2903 :    
2904 :     This required a minor change to install.sh because the name of the
2905 :     metadata directory (default: .cm) is actually configurable at
2906 :     installation time.

2921 :     Description:
2922 :    
2923 :     Added previously missing support for many socket-related functions
2924 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
2925 :     for the voluminous patch!
2926 :    
2927 :     (I have not tested this patch under win32 yet.)
2928 :    
2929 : mblume 1490 Here is David's e-mail:
2930 :    
2931 :     Hi,
2932 :    
2933 :     Attached to this email you find a diff against sml/nj 110.45
2934 :     that will enable socket support under Windows.
2935 :    
2936 :     To apply the patch (using unix or cygwin)
2937 :     1) gunzip runtime.diff.gz
2938 :     2) "cd" into "src/runtime" in the source tree of a fresh
2939 :     110.45 installation.
2940 :     3) patch -p 1 < [your/path/to]runtime.diff
2941 :    
2942 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2943 :     I only ran a few tests for basic socket client functionality
2944 :     (which worked fine). Especially the functions that use ioctl
2945 : mblume 1490 are not tested at all and might not work (see below).
2946 :    
2947 :     I implemented this since we want to move to a newer version of sml/nj
2948 :     but need socket support in order to use it. This is the first time I
2949 :     even had a look at the sml/nj source, so please review my changes
2950 :     before making this part of the distribution! Here are a few issues
2951 : blume 2155 that I think might be better for someone to solve who is more
2952 : mblume 1490 familiar with the sml/nj source (and socket programming):
2953 :    
2954 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2955 :     exception since I could not figure out what the windows equivalent
2956 :     of these functions is
2957 :    
2958 :     - In sockets-osdep.h there are a some #include statements that are
2959 :     only used in a few files that include sockets-osdep.h
2960 :    
2961 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2962 :     does not process its return value since I don't know how to
2963 :     report an error upwards.
2964 :    
2965 :     - It would probably be good to have a call to WSACleanup() when
2966 : blume 2155 the library is unloaded (if there is such a possibility).
2967 : mblume 1490 Otherwise I think Windows will take care of this automatically
2968 :     when the process finishes.
2969 :    
2970 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2971 :     no idea if that is actually the proper replacement on Windows.
2972 :    
2973 :     - All these issues are marked in the code by "FIXME" comments.
2974 :    
2975 : blume 2155 We use sml/nj extensively in our products and are quite happy
2976 :     with it. I hope this contribution will help you.
2977 : mblume 1490
2978 :     Keep up the good work!

3056 :    
3057 :     Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
3058 :     of SML/NJ. The problem is that
3059 :    
3060 :     lib = dlopen(NULL, ...)
3061 :     f = dlsym(lib, "malloc");
3062 :    
3063 : blume 2155 does not work on Windows unless we explicitly export symbols
3064 :     such as 'malloc' during linking. We fixed this by explicitly
3065 : allenleung 1468 exporting the required symbols with the magic gcc incantation:
3066 :    
3067 :     -Wl,--export-all cygwin.def
3068 :    
3069 :     where cygwin.def is a file containing all the symbols that
3070 : blume 2155 we wish to export.
3071 : allenleung 1468
3072 : blume 2155 I suspect this is a Windows problem and we'll have to
3073 :     do the same (somehow with windows compilers) when
3074 : allenleung 1468 we build the native win32 version with the system
3075 : blume 2155 calls LoadLibrary/GetProcAddress.

3201 :     Description:
3202 :    
3203 :     I modified the read-eval-print loop so that the autoloader gets
3204 :     invoked whenever the prettyprinter tries to look up a symbol that
3205 :     is not currently defined in the toplevel environment but which
3206 :     appears in CM's autoload registry. As a result, we see far fewer of
3207 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3208 :    
3209 :     In addition to this I tried to clean up some pieces of the Basis
3210 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3211 :     instances of these ?.Foo.Bar.xxx names from being printed.
3212 :    
3213 :     The mechanism that picks names for types still needs some work, though.
3214 :     (Right now it seems that if there is a type A.t which is defined to
3215 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3216 :     "?.B.u" although the perhaps more sensible solution would be to use
3217 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3218 :     a chain of DEFtycs not farther than there are corresponding toplevel
3219 :     names in the current environment.)

3225 :     Description:
3226 :    
3227 :     Another installer tweak: All the ML code for the installer is now
3228 :     compiled during CMB.make and put into a little library called
3229 :     $smlnj/installer.cm. The installation then simply invokes
3230 :    
3231 :     sml -m $smlnj/installer.cm
3232 :    
3233 :     and everything happens automagically.
3234 :    
3235 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3236 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3237 :     and BINDIR.
3238 :    
3239 :     The new scheme guarantees that the ML code responsible for the installation
3240 :     is in sync with the APIs of the main system. Also, the installer is
3241 :     somewhat faster because the installer script is precompiled.

3258 :     Tag: blume-20030924-sockets
3259 :     Description:
3260 :    
3261 :     1. Fixed SOCKET API and implementation to match Basis spec.
3262 :     This required changing the internal representation of sockets to one
3263 :     that remembers (for each socket file descriptor) whether it is currently
3264 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3265 :     call is made only if the state actually needs to change).
3266 :    
3267 :     2. OS-specific details of sockets were moved into separate files, thus
3268 :     making it possible to unify the bulk of the socket implementations
3269 :     between Unix and Win32.
3270 :    
3271 :     3. CML's socket API changed accordingly.
3272 :     (Note that we need to remove non-blocking functions from this API
3273 :     since they are redundant in the case of CML!)
3274 :    
3275 :     4. CML's socket implementation now makes use of non-blocking functions
3276 :     provided by Basis, thus removing all OS-dependent code from this part
3277 :     of CML.
3278 :    
3279 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3296 :     Description:
3297 :    
3298 :     1. new-install.sh -> install.sh
3299 :     2. changed default CM "metadata" directory name to ".cm" (instead of "CM")
3300 :     3. tweaked installer so that another name instead of .cm can be chosen
3301 :     at install time (by setting the CM_DIR_ARC environment variable
3302 :     during installation); once installation is complete, the name is
3303 :     fixed

3320 :     Description:
3321 :    
3322 :     1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
3323 :     this seems to be controversial at the moment) and used those in
3324 :     Posix.ProcEnv.times.
3325 :    
3326 :     2. Added Time.{from,to}Nanoseconds to Time.
3327 :    
3328 :     3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
3329 :     For example, fromLargeInt never needs to look at more than 3 "big
3330 :     digits" to get its 53 bits of precision.

3336 :     Description:
3337 :    
3338 :     Added an entry to the primitive environment
3339 :     (compiler/Semant/statenv/prim.sml) for int32->real64 conversion and
3340 :     added code to compiler/CodeGen/main/mlriscGen.sml to implement it.
3341 :    
3342 :     Removed some of the "magic" constants in real64.sml and replaced them
3343 :     with code that generates these values from their corresponding
3344 :     integer counterparts.
3345 :    
3346 :     Made all(?) the slice-related changes to the Basis and made everything
3347 :     compile again...

3391 :     Tag: blume-20030909-installer
3392 :     Description:
3393 :    
3394 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3395 :     Modified config/install.bat to take advantage of it. Also modified
3396 :     config/install.sh (and called it config/new-install.sh) to take advantage
3397 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3398 :     independent.)
3399 :    
3400 :     The installer can now install everything under Win32
3401 :     as well as under *nix as long as it compiles.
3402 :    
3403 :     Other changes:
3404 :    
3405 :     - made CML compile again under Win32
3406 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3407 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3408 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3409 :     same as type int; under Win32 it isn't
3410 :     - fixed some slice-related problems in the win32-specific parts of CML
3411 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3412 :     (under Win32, the volume name is case-insensitive, and the
3413 :     OS.Path code compares volume names for equality)

3419 :     Description:
3420 :    
3421 :     Made Win32 version of OS.FileSys.fullPath return current directory
3422 :     when given an empty string. This is what the spec says, and incidentally,
3423 :     CM depends on it. (CM otherwise goes into an infinite loop in certain
3424 :     cases when presented with the name of a non-existing .cm file.)

3429 : mblume 1352 Tag: blume-20030905-slices-etc
3430 : mblume 1350 Description:
3431 :    
3432 :     1. Changed interface to vectors and arrays in Basis to match
3433 :     (draft) Basis spec.
3434 :     2. Added signatures and implementations of slices according to
3435 :     Basis spec.
3436 :     3. Edited source code throughout the system to make it compile again
3437 :     under 1. and 2. (In some cases code had to be added to have it
3438 :     match the new signatures.)
3439 :     4. MLRISC should be backward-compatible: the copies of the originals
3440 :     of files that needed to change under 3. were retained, the .cm files
3441 :     check the compiler version number and use old versions when
3442 :     appropriate.
3443 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3444 :     dirstream -> string option (in accordance with Basis spec).
3445 :     6. When generating code that counts lines, ml-lex used function
3446 :     CharVector.foldli, taking advantage of its old interface.
3447 :     This has been replaced with the corresponding code from
3448 :     CharVectorSlice. (html-lex must be re-lexed!)
3449 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3450 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3451 :     8. Removed temporary additions (fromInternal, toInternal) from the
3452 :     (now obsolete) IntInf in smlnj-lib/Util.
3453 :     9. Cleaned up structure Byte.
3454 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3455 :     Cleaned/corrected implementation of Date.
3456 :     (Still need to check for correctness; implement better canonicalizeDate.)
3457 :     11. Added "scan" to signature IEEE_REAL.
3458 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3459 :     mod and rem when second operand is 2 (for parity checks).]
3460 :     13. Changed representation of type Time.time, using a single IntInf.int
3461 :     value counting microseconds. This considerably simplified the
3462 :     implementation of structure Time. We now support negative time
3463 :     values; scan and fromString handle signs.
3464 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3465 :     ArraySlice).

3470 :     Tag: blume-20030828-intinf
3471 :     Description:
3472 :    
3473 :     This is a major update which comes with a version number bump
3474 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3475 :     and an implementation of IntInf in the Basis.
3476 :    
3477 :     There are a fairly large number of related changes and updates throughout
3478 :     the system:
3479 :    
3480 :     Basis:
3481 :     - Implemented IntInf.
3482 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3483 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3484 : mblume 1347 - Added FixedInt as a synonym for Int32.
3485 :    
3486 :     compiler:
3487 :     * Added support for a built-in intinf type.
3488 :     - literals
3489 :     - pattern matching
3490 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3491 :     - overloading on literals and operations
3492 :    
3493 :     This required adding a primitive type intinf, some additional
3494 :     primops, and implementations for several non-trivial intinf
3495 :     operations in Core. (The intinf type is completely abstract
3496 :     to the compiler; all operations get delegated back to the Core.)
3497 :    
3498 :     * Intinf equality is handled by polyequal. However, the compiler
3499 :     does not print its usual warning in this case (since polyequal
3500 :     is the right thing to do there).
3501 :    
3502 :     * Improved the organization of structure InlineT.
3503 :    
3504 :     * A word about conversion primops:
3505 :     If conversions involving intinf do not cancel out during
3506 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3507 : mblume 1347 Since all core access must be resolved already during the FLINT
3508 :     translate phase, it would be too late a the time of CPS contract
3509 : mblume 1348 to add new Core calls. For this reason, conversion primops
3510 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3511 :     they are supposed to convert, and 2. the Core function that
3512 :     can help with this conversion if necessary. If CPS contract
3513 : mblume 1348 eliminates a primop, then the associated Core function becomes
3514 :     dead and goes away. Intinf conversion primops that do not get
3515 :     eliminated by CPS contract get rewritten into calls of their
3516 :     core functions by a separate, new phase.
3517 : mblume 1347
3518 :     interactive system:
3519 :     - Control.Print.intinfDepth controls max length of intinf constants
3520 :     being printed. (Analogous to Control.Print.stringDepth.)
3521 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3522 :     duplicates; replaced some of the code with code that makes better
3523 :     use of library functionality.
3524 :    
3525 :     CM:
3526 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3527 :     are no longer silent.
3528 :    
3529 :     CKIT:
3530 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3531 :     in favor of LargeInt -- which is now the same as IntInf.
3532 :     CKIT-knowledgable people should check whether this is what's
3533 :     intended and otherwise change things back to using Int32 or
3534 :     FixedInt.
3535 :    
3536 :     Throughout the code:
3537 : mblume 1348 Started using IntInf.int literals and built-in operations
3538 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3557 :     Tag: blume-20030811-windows
3558 :     Description:
3559 :    
3560 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3561 :    
3562 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3563 :    
3564 :     This patch restores SML/NJ's ability to run under win32. There are a
3565 :     number of changes, including fixes for several bugs that had gone
3566 :     unnoticed until now:
3567 :    
3568 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3569 :     trying to run the win32 version from within cygwin.)
3570 :    
3571 :     - There are a number of simple .bat scripts that substitute for their
3572 :     corresponding Unix shell-scripts. (See below.)
3573 :    
3574 :     - The internals of ml-build have been modified slightly. The main
3575 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3576 :     using OS.Process.system, the ML process delegates this task back
3577 :     to the script. Otherwise problems arise in mixed environments such
3578 :     as Cygwin where scripts look and work like Unix scripts, but
3579 :     where OS.Process.system cannot run them.
3580 :    
3581 :     - In CM, the srcpath pickler used native pathname syntax -- which
3582 :     is incorrect in the case of cross-compilation. The new pickle format
3583 :     is independent of platform-specific naming conventions.
3584 :    
3585 :     - Path configuration files (such as lib/pathconfig) can now choose
3586 :     between native and standard syntax. Placing a line of the form
3587 :    
3588 :     standard!
3589 :    
3590 :     into the file causes all subsequent paths to be interpreted using
3591 :     CM standard pathname syntax (= Unix conventions); a line
3592 :    
3593 :     native!
3594 :    
3595 :     switches back to native style. This was needed so that
3596 :     path config files can be written portably, see src/system/pathconfig.
3597 :    
3598 :     - Runtime system:
3599 :    
3600 :     - win32-filesys.c: get_file_time and set_file_time now
3601 :     access modification time, not creation time.
3602 :    
3603 :     - I/O code made aware of new array representation.
3604 :    
3605 :     - Bug fixes in X86.prim.masm.
3606 :    
3607 :     - src/system/makeml made aware of win32. (For use under cygwin
3608 :     and other Unix-environments for windows.)
3609 :    
3610 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3611 :     which caused BinIO.inputAll to fail consistently.
3612 :    
3613 :     .bat scripts:
3614 :    
3615 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3616 :    
3617 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3618 :     applications (sml, ml-yacc, ml-lex).
3619 :     - ml-build.bat: analogous to ml-build.
3620 :     - config\install.bat: Analogous to config/install.sh. This requires
3621 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3622 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3623 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3624 :     and the bootfile hierarchy must have been unpacked under
3625 :     sml.boot.x86-win32.
3626 :     The script is very primitive and does a poor job at error checking.
3627 :     It only installs the base system, ml-lex, and ml-yacc. No other
3628 :     libraries are being installed (i.e., you get only those that
3629 :     are part of the compiler.)
3630 :     - link-sml.bat: analogous to .link-sml, but not currently used
3631 :    
3632 :     Unrelated bug fixes:
3633 :    
3634 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3635 :     types.
3636 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3637 :     otherwise.)

3678 :     This mainly affects the quality of error messages. However, some
3679 :     of the code is now more straightforward than before. (Treatment of
3680 :     the above four constructs in translate.sml is much simpler than
3681 :     the "macro-expansion" that was going on before. Plus, the mach-
3682 :     compiler no longer gets invoked just to be able to compile an
3683 :     if-expression.)
3684 :    
3685 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3686 :     interactive loop.

3693 :    
3694 : blume 2155 Ported the runtime system to cygwin, which uses the unix
3695 : allenleung 1327 x86-unix bin files. Missing/buggy features:
3696 :    
3697 : blume 2155 o getnetbyname, getnetbyaddr: these functions seem to be missing in
3698 : allenleung 1327 the Cygwin library.
3699 :     o Ctrl-C handling may be flaky.
3700 :     o Windows system calls and Windows I/O are not supported.
3701 :    
3702 :     A new set of binfiles is located at:
3703 :    
3704 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3705 :    
3706 :     This is only needed for bootstrapping the cygwin version of smlnj.
3707 :     Other x86 versions can use the existing binfiles.

3863 :     Another small change is that ppDec tries to give more information

3865 :     broken in some mysterious way if the functor's body's signature
3866 :     has not been declared by ascription but gets inferred from the

3968 :     0. John Reppy made several modifications to the SML/NJ library.
3969 :     In particular, there is a shiny new controls-lib.cm.
3970 :    
3971 :     1. Pushed new controls interface through compiler so that everything

3973 :    
3974 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3975 :     SML/NJ library (so that CML compiles again).
3976 :    
3977 :     3. Modified init scripts because XXX_DEFAULT environment variables

3986 :     Description:
3987 :    
3988 :     All pseudo-ops emitted before the first segment declaration
3989 :     such as TEXT, DATA, and BSS directives are assumed to be global
3990 :     declarations and are emitted first in the assembly file. This is
3991 :     useful in a number of situations where one has pseudo-ops that are not
3992 :     specific to any segment, and also works around the constraint that one
3993 :     cannot have client pseudo-ops in the TEXT segment.
3994 :    
3995 :     Because no segment is associated with these declarations it is
3996 :     an error to allocate any space or objects before the first segment
3997 :     directive and an exception will be raised. However, we cannot make
3998 :     this check for client pseudo-ops.
3999 :    
4000 :     These top level declarations are a field in the CFG graph_info.

4026 :    
4027 :     Applied the following bugfix provided by Emden Gansner:
4028 :    
4029 :     Output is corrupted when outputSubstr is used rather than output.
4030 :    
4031 : blume 2155 The problem occurs when a substring
4032 : blume 1189
4033 :     ss = (s, dataStart, dataLen)
4034 :    
4035 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
4036 :     avail bytes of s, starting at index dataStart, are copied into the
4037 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
4038 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
4039 :     starting this copy at index dataStart+avail in s, the current code
4040 : blume 1189 starts the copy at index avail.
4041 :    
4042 :     Fix:
4043 :     In text-io-fn.sml, change line 695 from
4044 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
4045 : blume 2155 to

4066 :     directly where appropriate.
4067 :    
4068 :     Some more extensive power-of-two support was added to the x86 instruction
4069 :     selector (avoiding expensive divs, mods, and muls where they can be
4070 :     replaced with cheaper shifts and masks). However, this sort of thing
4071 :     ought to be done earlier, e.g., within the CPS optimizer so that

4086 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
4087 :     The problem was with quotient = 0, because that alone does not tell

4097 :     Description:
4098 :    
4099 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
4100 :    
4101 :     Primops have changed. This means that the bin/boot-file formats have
4102 :     changed as well.
4103 :    
4104 :     To make sure that there is no confusion, I made a new version.
4105 :    
4106 :    
4107 :     CHANGES:
4108 :    
4109 :     * removed REMT from mltree (remainder should never overflow).
4110 :    
4111 :     * added primops to deal with divisions of all flavors to the frontend
4112 :    
4113 :     * handled these primops all the way through so they map to their respective
4114 :     MLRISC support
4115 :    
4116 :     * used these primops in the implementation of Int, Int32, Word, Word32
4117 :    
4118 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
4119 :    
4120 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
4121 :    
4122 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
4123 :     floating point
4124 :    
4125 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
4126 :     and Real (but Real.abs maps to a separate floating-point-only primop)
4127 :    
4128 :    
4129 :     TODO items:
4130 :    
4131 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
4132 :     instructions because the machine instruction encoder cannot handle
4133 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
4134 :     REM in the first place, and REM is supported by the x86 machine coder.)
4135 :    
4136 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
4137 :     selection phase. (The two can be streamlined because the hardware
4138 :     delivers both quotient and remainder at the same time anyway.)
4139 :    
4140 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
4141 :     (Currently the behavior is inconsistent both across architectures and
4142 :     wrt. the draft Basis spec.)
4143 :    
4144 :     * Word8 should eventually be handled natively, too.
4145 :    
4146 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
4147 :     as if there currently is no execution path that could trigger it in
4148 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
4149 :     hold for things like multiplication and division.)

4154 :     Tag: blume-20020327-mlrisc-divisions
4155 :     Description:
4156 :    
4157 :     Added support for all four division operations (ML's div, mod, quot,
4158 :     and rem) to MLRISC. In the course of doing so, I also rationalized
4159 :     the naming (no more annoying switch-around of DIV and QUOT), by
4160 :     parameterizing the operation by div_rounding_mode (which can be either
4161 :     DIV_TO_ZERO or DIV_TO_NEGINF).
4162 :    
4163 :     The generic MLTreeGen functor takes care of compiling all four
4164 :     operations down to only round-to-zero div.
4165 :    
4166 :     Missing pieces:
4167 :    
4168 :     * Doing something smarter than relying on MLTreeGen on architectures
4169 :     like, e.g., the x86 where hardware division delivers both quotient and
4170 :     remainder at the same time. With this, the implementation of the
4171 :     round-to-neginf operations could be further streamlined.
4172 :    
4173 :     * Remove inlining support for div/mod/rem from the frontend and replace it
4174 :     with primops that get carried through to the backend. Do this for all
4175 :     int and word types.

4180 :     Tag: blume-20020325-divmod
4181 :     Description:
4182 :    
4183 :     I improved (hopefully without breaking them) the implementation of Int.div,
4184 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
4185 :     advantage of the following observations:
4186 :    
4187 :     Let q = x quot y r = x rem y
4188 :     d = x div y m = x mod y
4189 :    
4190 :     where "quot" is the round-to-zero version of integer division that
4191 :     hardware usually provides. Then we have:
4192 :    
4193 :     r = x - q * y where neither the * nor the - will overflow
4194 :     d = if q >= 0 orelse x = q * y then q el
