567 :     Description:
568 :    
569 :     3rd merge of base from primop-branch-3 into the trunk.
570 :     Additional bug fixes included:
571 :    
572 :     * Timer.cpu_timer, etc. type printing corrected (by making
573 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
574 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by

579 :     Date: 2007/05/31 11:40:00 CDT
580 :     Description:
581 :    
582 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
583 :    
584 :     Also, changed the handling of "no core access": When translate.sml
585 :     needs access to a core exception at a time when the core has not
586 :     been set up yet (this only happens when compiling system/smlnj/init/*),
587 :     then don't bother generating the corresponding tests.
588 :    
589 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
590 :     the exception. Unfortunately, that confuses the plambda type checker.
591 :     Moreover, it does not do any good, because at runtime we don't expect
592 :     such an exception to be ever raised. (The code in system/smlnj/init/*
593 :     has to be written very carefully with this in mind!)

605 :     Description:
606 :    
607 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
608 :     with an explicit test for zero division. This should fixes several
609 :     regressions and makes it possible for downstream optimization phases
610 :     to treat these operations as "pure" when they are applied to unsigned

626 :    
627 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
628 :     for bugs #1415 and #1416. We also now correctly handle format characters that

633 :     Date: 2007/05/23 22:30:00 CDT
634 :     Description:
635 :    
636 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
637 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
638 :    
639 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
640 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
641 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
642 :     while running CMB.make. The point is that the single symbol
643 :     NO_PLUGINS is definde in all three cases.)
644 :    
645 :     I changed the three locations within the sources that get compiled
646 :     during CMB.make where ml-yacc or ml-lex input is processed: When
647 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
648 :     is bypassed.
649 :    
650 :     When bootstrapping new versions of the compiler, there can be
651 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
652 :     are not available or otherwise not operational. In this case one can
653 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
654 :     do so, the following command should be issued at the interactive
655 :     prompt:
656 :    
657 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
658 :    
659 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
660 :     files that normally would be generated by ml-yacc and ml-lex.
661 :     (Copies of these files are in the repository.)

677 :     Description:
678 :    
679 :     Changed the installation mechanism for CM tool plugins. These are
680 :     just libaries and now get installed like ordinary libaries.
681 :    
682 :     There are now a number of new installation targets that give some
683 :     fine-grain control over what classes and suffixes are known, and what
684 :     they will map to.
685 :     See config/targets for details.
686 :    
687 :     The code that caused plugin installation as part of running a
688 :     tool's "build" script has been removed. (The build script is for
689 :     building, not for installing.)

694 :     Description:
695 :    
696 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
697 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
698 :     CM fail if a shell tool reports a non-success exit status. If
699 :     the control is set to true, then CM will press on after tool failures
700 :     in the event that the target files exist (even though they are
701 :     considered outdated). Turning the control to true can be useful for
702 :     bootstrapping.

707 :     Description:
708 :    
709 :     Merge of ml-lpt revisions for 110.64.
710 :    
711 :     The name of several ml-lpt-lib modules has changed:
712 :     Repair => AntlrRepair
713 :     StreamPos => AntlrStreamPos
714 :     ErrHandlerFn => AntlrErrHandler
715 :     EBNF => AntlrEBNF
716 :    
717 :     The ml-antlr specification format has changed: declarations such as
718 :     %tokens and nonterminal definitions can occur *multiple* times in the
719 :     same specification. The semantics are such that each new declaration
720 :     extends the previous ones. This does not apply to %start or %name,
721 :     of course.
722 :    
723 :     Importing a grammar via %import now includes *all* declarations in from
724 :     the imported grammar, except for %name, %entry, and %start. Tokens
725 :     and nonterminals can be dropped using the new %dropping clause of the
726 :     %import directive; the separate %drop and %extend have been removed.
727 :    
728 :     We now allow optional type annotations on nonterminals, using the %nonterms
729 :     directive as in ml-yacc.
730 :    
731 :     The refcell construct is now implemented using SML's regular reference
732 :     cells, so the :== and !! notation has been deprecated.
733 :    
734 :     The ml-antlr tool now does much more checking of specifications, and
735 :     its error messages have been greatly improved. Error repair for
736 :     generated parsers has been completely rewritten, and is now both
737 :     much faster and more accurate.
738 :    
739 :     ml-ulex is now more lenient with escape codes (non-SML-standard
740 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
741 :     Also, character classes may now include a "-" character at the beginning
742 :     as is standard in most other regexp tools.
743 :    
744 :     All of these changes are documented in the user guide, which has
745 :     been updated and improved with this merge.

751 :     Description:
752 :    
753 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
754 :     Significant changes in FLINT and the front end, mostly having to do
755 :     with a reorganized system for handling primops. Various bug fixes
756 :     and improvements in printing signatures.

761 :     Description:
762 :    
763 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
764 :     The ml-antlr specification format has changed: declarations such as
765 :     %tokens and nonterminal definitions can occur *multiple* times in the
766 :     same specification. The semantics are such that each new declaration
767 :     extends the previous ones. Grammar extension constructs have also
768 :     changed. We now allow type annotations on nonterminals. Finally,
769 :     the refcell construct is now implemented using SML's regular reference
770 :     cells, so the :== and !! notation has been deprecated. All of these
771 :     changes will appear in the 110.64 user guide for ml-lpt.
772 :    
773 :     The ml-antlr tool now does much more checking of specifications, and
774 :     its error messages have been greatly improved. There has also been
775 :     some work on the error repair process for generated parsers, but this
776 :     will be further improved in 110.64.

882 :     promoted to tagless pair.

891 :     val a1 = Word8Array.array(a1, 0w0);

893 :    
894 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
895 :     of the range -128 ... 127. I've changed the code so that the range
896 :     check is disabled. Only the low order 8 bits of the immediate operand

904 :    
905 :     Eliminated any mention of lexgen. (Lexgen was an early precursor
906 :     to ml-ulex.)
907 :

937 :     Date: 2007/01/31
938 :     Description:
939 :    
940 :     Brought ml-lpt manual up-to-date with the code. Many minor
941 :     improvements to the tools, and a few minor bugfixes. Prepared
942 :     ml-lpt-lib for integration with new UTF8 structure. Changed
943 :     the interface for creating streams in ml-ulex (we now support
944 :     stream creation from several kinds of sources). Overall, the
945 :     tools are now quite stable, and their interfaces are unlikely to
946 :     change in a way that would break compatibility. More work,
947 :     however, is needed in the documentation.

952 :     Description:
953 :    
954 :     Implemented library installer. Moved CM plugin code for
955 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
956 :     their respective trees. Implemented CM plugin for ml-ulex
957 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
958 :     and ml-antlr.
959 :    
960 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
961 :     CM tools. (It turns out to be too messy to do otherwise because
962 :     there is too much code that during installation relies on the presence
963 :     of these tools -- resulting in a tricky ordering problem.)

968 :     Description:
969 :    
970 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
971 :     Modified CM's startup code to use shiftArgs as it processes
972 :     command line arguments. This way, the init code in each .sml-file
973 :     or library that is mentioned at the top level will see only
974 :     those arguments that have not yet been processed at this point.
975 :     In other words, the init code can "seize control" and process the
976 :     remaining command line.

1043 :     Description:
1044 :    
1045 :     Added code to CM's "standard shell tool" implementation which
1046 :     causes it to tolerate (with a warning) the situation where the shell
1047 :     command fails (e.g., due to the shell command's non-existence)
1048 :     as long as all target files exist.
1049 :    
1050 :     This makes it possible to, e.g., build ml-yacc from sources even if
1051 :     svn checkout messed up the time stamps on files in such a way that
1052 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
1053 :     be needed to re-process yacc.grm, but obviously it might not yet be
1054 :     available at that time.)

1060 :    
1061 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
1062 :     recvVecFromNB' in the SOCKET signature. This error is actually
1063 :     in the SML Basis specification too.

1093 :     Tag: release-110.60
1094 :     Description:
1095 :    
1096 :     New working release (110.60). NEW BOOTFILES!
1097 :    
1098 :     This is the first subversion-hosted release. There are also changes
1099 :     to the directory layout. Here is a table:
1100 :    
1101 :     (All pathnames are relative to the SML/NJ "root" directory.)
1102 :    
1103 :     config -> config
1104 :    
1105 :     src/cm -> base/cm
1106 :     src/compiler -> base/compiler
1107 :     src/runtime -> base/runtime
1108 :     src/system -> base/system
1109 :    
1110 :     src/cm/pgraph -> pgraph
1111 :    
1112 :     src/READMES -> base/READMES
1113 :     src/$notefile -> base/NOTES/$notefile
1114 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1115 :     MACOSXINSTALL WININSTALL
1116 :    
1117 :     src/smlnj-lib -> smlnj-lib
1118 :     src/MLRISC -> MLRISC
1119 :     ckit -> ckit
1120 :     src/cml -> cml
1121 :     src/eXene -> eXene
1122 :     src/heap2asm -> heap2asm
1123 :     src/lexgen -> lexgen
1124 :     src/ml-burg -> ml-burg
1125 :     src/ml-lex -> ml-lex
1126 :     src/ml-yacc -> ml-yacc
1127 :     src/ml-nlffi-lib -> nlffi/lib
1128 :     src/ml-nlffigen -> nlffi/gen
1129 :     src/smlnj-c -> smlnj-c
1130 :     src/tools/TraceDebugProf -> trace-debug-profile
1131 :    
1132 :     In addition, there is also a new
1133 :    
1134 :     ml-lpt
1135 :    
1136 :     directory containing two new program generator tools: ml-ulex and
1137 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1138 :     LL(k) parser generator). These tools are currently "beta-quality"
1139 :    
1140 :     The latest versios of the sources can now be obtained anonymously
1141 :     via subversion. For this, it is useful to first check out
1142 :    
1143 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1144 :    
1145 :     and put the resulting directory on your shell's PATH. This provides
1146 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
1147 :     and refresh-all.sh.
1148 :    
1149 :     To create a freshly checked-out copy of the sources, do
1150 :    
1151 :     checkout-all.sh [dir]
1152 :    
1153 :     where dir is the optional SML/NJ root directory (default is ".").
1154 :    
1155 :     This creates the above directory layout. Each subdirectory of
1156 :     the root is under individual subversion control. The stat-all.sh
1157 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
1158 :     each of these subtrees.
1159 :

1161 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
1162 : blume 2155 Date: 2006/11/02 12:20:00 CST
1163 :     Description:
1164 :    
1165 :     Reorganized directory layout.
1166 :    
1167 :     This is a temporary solution, more reorganization is to come.
1168 :    
1169 :     The basic idea is to have a number of toplevel trees, each corresponding
1170 :     to a well-defined part of the overall system. Each part can be
1171 :     maintained individually, even in separate source repositories,
1172 :     although currently we still serve everything out of the main
1173 :     smlnj-gforge tree.
1174 :    
1175 :     Installer and and scripts have been updated to reflect the new
1176 :     layout. The installer (base/src/system/smlnj/installer) is now
1177 :     "scriptable" to avoid burning too much knowledge about the
1178 :     layout into SML source code. The main script used by the installer
1179 :     is in config/actions.
1180 :    
1181 :     The main change is that many of the subdirectories of what used to
1182 :     be known as "src" have moved to the toplevel. The "src" directory
1183 :     itself has moved down into a subtree called "base". (We may eventually
1184 :     get rid of the extra level of indirection represented by "src".)
1185 :    
1186 :     The layout is now as follows:
1187 :    
1188 :     toplevel tree name | default repository
1189 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1190 :     -------------------+----------------------------------------------------
1191 :     config | $gf/config/trunk
1192 :     |
1193 :     base | $gf/sml/trunk
1194 :     |
1195 :     smlnj-lib | $gf/smlnj-lib/trunk
1196 :     MLRISC | $gf/MLRISC/trunk
1197 :     |
1198 :     ml-yacc | $gf/ml-yacc/trunk
1199 :     ml-lex | $gf/ml-lex/trunk
1200 :     ml-burg | $gf/ml-burg/trunk
1201 :     lexgen | $gf/lexgen/trunk
1202 :     heap2asm | $gf/heap2asm/trunk
1203 :     |
1204 :     cml | $gf/cml/trunk
1205 :     eXene | $gf/eXene/trunk
1206 :     ckit | $gf/ckit/trunk
1207 :     nlffi | $gf/nlffi/trunk
1208 :     |
1209 :     smlnj-c | $gf/smlnj-c/trunk
1210 :    
1211 :     In $gf/admin there are a few useful shell scripts for checking out
1212 :     and maintaining the entire collection of trees:
1213 :    
1214 :     admin/checkout-all.sh [dir]
1215 :     -- optionally creates dir and checks out all trees from their
1216 :     default repositories; if dir is missing, checkout into .
1217 :     admin/refresh-all.sh [dir]
1218 :     -- looks at all trees (from the above list) in dir (default: .)
1219 :     and runs "svn update" if the tree exists and is under
1220 :     subversion control;
1221 :     non-existing or non-subversion trees are skipped
1222 :     admin/stat-all.sh [dir]
1223 :     -- like refresh-all.sh, but runs "svn stat" instead

1369 :     Description:
1370 :    
1371 :     Hooked code for Darwin-specific Intel ABI into main compiler.
1372 :     (This is a temporary solution which relies on the fact that the
1373 :     compiler itself does not use NLFFI. Eventually we need to divorce
1374 :     intel mac from generic x86 unix code and make separate sets of binaries.)

1403 :     Description:
1404 :    
1405 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1406 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1407 : blume 2155 at the time when config/preloads is processed, the library has to
1408 : mblume 1878 be referred to by another name. In 110.57 this would be
1409 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1410 :     to be valid as well.)

1430 :     the physical location of basis.cm has changed). Also, corrected the

1465 :     Tag: blume-22051115-versiontool
1466 :     Description:
1467 :    
1468 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1469 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1470 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1471 :     it. Instead, it has the status of "user code", so it should use
1472 :     $/basis.cm to refer to the Basis library. (At least that's true for
1473 :     the purpose of bootstrapping the previous change. In the future it
1474 :     might make sense to have versiontool.cm refer to
1475 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1476 :     compiler itself uses.)
1477 :    
1478 :     Also patched src/system/testml to have it activate those extra anchor
1479 :     bindings in config/extrapathconfig.

1484 :     Tag: blume-22051115-libraries
1485 :     Description:
1486 :    
1487 :     This change affects the way the following libraries are tied into
1488 :     the system:
1489 :    
1490 :     $/basis.cm
1491 :     $/smlnj-lib.cm
1492 :     $/pp-lib.cm
1493 :     $/controls-lib.cm
1494 :     $/html-lib.cm
1495 :     $/ml-yacc-lib.cm
1496 :    
1497 :     These libraries are now internally (as seen from the source code
1498 :     of the implementation itself) known by the following names:
1499 :    
1500 :     $smlnj/basis/basis.cm
1501 :     $smlnj/smlnj-lib/smlnj-lib.cm
1502 :     $smlnj/smlnj-lib/pp-lib.cm
1503 :     $smlnj/smlnj-lib/controls-lib.cm
1504 :     $smlnj/smlnj-lib/html-lib.cm
1505 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1506 :    
1507 :     This makes it possible to work with code that requires different
1508 :     versions of these libraries, and which refers to these libraries using
1509 :     their "default" names (i.e., the first set of names above). In other
1510 :     words, one can un-define or re-define those default names without
1511 :     compromising the proper functioning of the compiler itself.
1512 :    
1513 :     A similar procedure had already been performed for several of the
1514 :     MLRISC libraries that are linked into the compiler. I did some
1515 :     cleanup on this code.
1516 :    
1517 :     A new file in the config directory (named extrapathconfig) is
1518 :     responsible for setting up path anchors that the compiler itself does
1519 :     not need, but that are typically required by user code.

1702 :     after configuration variables have been changed.
1703 :    
1704 :     CM.redump_heap : string -> unit
1705 :    
1706 :     This is much like SMLofNJ.exportML, but starting from the resulting
1707 : blume 2155 heap does not return to the caller of CM.redump_heap but
1708 : mblume 1792 restarts the interactive system from scratch. The original call of
1709 :     CM.redump_heap does not return but ends the interactive session.
1710 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1711 :    
1712 :     Internally, redump_heap winds the dynamic execution context back to
1713 :     the point where the original heap image was created and re-executes
1714 :     the heap image generation code in the boot code.

1831 :     Description:
1832 :    
1833 :     Implemented new (but still experimental) heap2exec facility. This is
1834 :     tested under Mac OS X and should work under Linux (will test shortly).
1835 :     It will probably also work on the Sparc (will test some time later).
1836 :    
1837 :     - removed old "HACKED_STANDALONE" hack from runtime
1838 :    
1839 :     To be able to test this, uncomment the request for "heap2asm" in
1840 :     config/targets prior to installation. (Notice that this is different
1841 :     from "heap2exec" mentioned below. Not a typo.)
1842 :    
1843 :     To perform an actual test, run the command
1844 :    
1845 :     $ bin/heap2exec heapfile execfile
1846 :    
1847 :     (You can put heap2exec on your shell's path.)
1848 :    
1849 :     For example, run
1850 :    
1851 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1852 :    
1853 :     This will create a standalone executable called "mly" which you can
1854 :     then invoke directly as a command.

1881 :    
1882 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1883 :     (On the Mac, it is big-endian. And that's currently our only

2000 :     Description:
2001 :    
2002 :     The compiler can now be compiled in a mode that makes structure Position
2003 :     equal to Int64. The default, however, is unchanged (Position = Int31)
2004 :     for the time being.
2005 :    
2006 :     To enable 64-bit positions, use the following procedure:
2007 :    
2008 :     1. Start sml
2009 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
2010 :     3. Type
2011 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
2012 :     4. Run CMB.make() as usual.
2013 :    
2014 :     This is barely tested. The only test so far was a little SML program
2015 :     counting the number of characters in an 8-gigabyte file by
2016 :     reading it character-by-character. That test was successful.
2017 :    
2018 :     In support of 64-bit positions, a number of new functions have been
2019 :     added to the runtime system.

2064 :    
2065 :     - In a previous commit, fixed a minor issue with how polyequal is being
2066 :     translated. In particular, the code now "looks through" abstractions.
2067 :     This results in slightly fewer polyEqual warnings and hopefully slightly
2068 :     more efficient code. Important examples for where this matters are
2069 :     the new int64 and word64 types.

2100 :     Structure Word64 is now (almost) complete, word literals and patterns
2101 :     seem to work. There are a few odd pieces missing. In particular,
2102 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2103 :     at the moment.
2104 :    
2105 :     Making Word64 official would mean that LargeWord becomes Word64. But
2106 :     this requires extreme care because most word-word conversions have to
2107 :     go through LargeWord, so making a mistake means loss of efficiency or
2108 :     worse. Eventually there will be a solution similar to (but actually
2109 :     simpler than) what I did with IntInf.

2137 :     =====================
2138 :    
2139 :     Also:
2140 :    
2141 :     - Changend config/srcarchiveurl from a file just
2142 :     containing the URL string into a file containing
2143 :     shell script code. The code has access to the $VERSION variable.
2144 :     - Made corresponding changes to config/install.sh and config/unpack.
2145 :     - Default contents of config/srcarchiveurl uses $VERSION and
2146 :     normally does not have to be edited to reflect a version change.
2147 :    
2148 :     (As a result, a version change can be done by just editing
2149 :     config/version, the rest is now automatic.)

2189 :     Tag: blume-20041020-standalone-backtrace
2190 :     Description:
2191 :    
2192 :     Added a mechanism for getting back-trace information from standalone
2193 :     programs. Here is how it works:
2194 :    
2195 :     1. The part of the program from which you want to get backtrace
2196 :     information (usually the whole program) should be wrapped with
2197 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
2198 :     main program could be modified from something like
2199 :    
2200 :     fun main (pgm, args) = ...
2201 :    
2202 :     to
2203 :    
2204 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2205 :    
2206 :     2. To be able to access BackTrace.monitor, you have to add
2207 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
2208 :     main function.
2209 :    
2210 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2211 :     CM might have created in the past for your project).
2212 :    
2213 :     4. Build the system using this command line:
2214 :    
2215 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2216 :     myprog.cm MyProg.main myprog
2217 :    
2218 :     instead of the usual
2219 :    
2220 :     ml-build myprog.cm MyProg.main myprog
2221 :    
2222 :     I changed a library name:
2223 :    
2224 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2225 :    
2226 :     New libraries:
2227 :    
2228 :     $smlnj-tdp/back-trace.cm
2229 :     -- when loaded causes the back-trace plugin to be installed
2230 :     $smlnj-tdp/coverage.cm
2231 :     -- when loaded causes the coverage plugin to be installed

2247 :     Description:
2248 :    
2249 :     * Test coverage tool added!
2250 :     * Further reorganization of tracing-, debugging-, and profiling support:
2251 :    
2252 :     - moved original BTImp -- now called BackTrace -- into a separate
2253 :     library called $/trace-debug-profile.cm
2254 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2255 :     - only the instrumentation mechanism is now left in the compiler proper
2256 :     - BackTrace module is a plugin which is NOT plugged in by default
2257 :     - Coverage module is another such plugin
2258 :    
2259 :     To get the benefits of any of these plugin modules, the code in
2260 :     question must be compiled with tdp instrumentation turned on. This
2261 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2262 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2263 :    
2264 :     Plugins are selected at link time. (Pre-compiled instrumented code
2265 :     can be re-loaded with different plugins in effect.) When an
2266 :     instrumented module is linked, whatever plugins are at that time
2267 :     enabled will come into effect for that module.
2268 :    
2269 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2270 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2271 :     To enable the coverage plugin, load the same library and invoke
2272 :     Coverage.install().
2273 :    
2274 :     Back-traces are generated automatically on uncaught exceptions and
2275 :     when the code in question explicitly invokes BackTrace.trigger().
2276 :    
2277 :     Coverage (and execution frequency-) information must be queried
2278 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2396 :     Description:
2397 :    
2398 :     Implemented some CM magic to have
2399 :     file src/compiler/TopLevel/main/version.sml
2400 :     generated automagically.
2401 :     The version is taken from two files: config/version and config/release.
2402 :     The first is expected to contain a two-part version number such as 110.49.
2403 :     The second should contain a single number, but it may be missing.
2404 :    
2405 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2406 :     time the version tool is loaded (which is the first time you say CMB.make),
2407 :     then the tool will increment the value stored in config/release every
2408 :     time CMB.make is invoked.
2409 :    
2410 :     The binfile format is now insensitive to anything beyond the first
2411 :     two components of a version number, so bumping the release does not render
2412 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2413 :     during development without invalidating existing binfiles.
2414 :    
2415 :     In any case, every CMB.make updates the date information in version.sml.

2429 :     Tag: blume-20040927-controls
2430 :     Description:
2431 :    
2432 :     Added two pieces of functionality to the Controls interface:
2433 :    
2434 :     1. val save'restore: 'a control -> unit -> unit
2435 :    
2436 :     grabs the current value of the control in stage 1 and restores it
2437 :     in stage 2.
2438 :    
2439 :     2. val set' : 'a control * 'a -> unit -> unit
2440 :    
2441 :     stores the given value into the control in stage 2 (i.e., delayed)
2442 :     but does all error checking in stage 1.
2443 :     (This is for string controls that need to do parse their argument --
2444 :     something that might fail. In some cases, notably in CM, one
2445 :     already knows the intended argument but wants to delay the actual
2446 :     assignment until a time when error recovery would be more difficult.)
2447 :    
2448 :     Changed the handling of controls in tool arguments to classes "sml" and
2449 :     "lazysml":
2450 :     - use Controls.save'restore as a more robust way of restoring the
2451 :     old value (in particular: without having to re-parse the string)
2452 :     - use controls to handle the "overload" keyword in the init group
2453 :     (I believe this change actually fixes a long-standing obscure bug.)

2458 :     Tag: blume-20040927-lazysml
2459 :     Description:
2460 :    
2461 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2462 :     difference to "sml" is that compilation is done with Control.lazysml
2463 :     set to true. A source of class "lazysml" is automatically recognized
2464 :     by a file name suffix of ".lml".
2465 :    
2466 :     In addition to the above feature, the original class "sml" now also
2467 :     supports a tool argument "lazy" which has the same effect. As a
2468 :     result, the following three lines are equivalent:
2469 :    
2470 :     foo.sml : lazysml
2471 :     foo.sml : sml (lazy)
2472 :     foo.sml (lazy)
2473 :    
2474 :     The setting goes into effect both during parsing and during
2475 :     compilation. The original setting is restored right after parsing and
2476 :     after compilation, respectively.
2477 :    
2478 :     In addition to all the above, there is also a general mechanism to set
2479 :     ANY of the "controls" that are available at the command line via
2480 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2481 :     apply as well. (In fact, "lazy" is implemented as a special case of
2482 :     the general mechanism.)
2483 :    
2484 :     The .cm file syntax uses a new keyword tool argument called "with".
2485 :     There are several ways of indicating the desired settings:
2486 :    
2487 :     foo.sml (with:parser.quotations=true)
2488 :     foo.sml (with:(name:parser.quotations value:true))
2489 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2490 :     foo.sml (with:(name1=value1 name2=value2 ...))
2491 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2492 :    
2493 :     etc.
2494 :    
2495 :     Another possible abbreviation is to leave out the =v or value:v part
2496 :     if the name refers to a boolean control (in which case the value is
2497 :     taken to be true). Thus, one could get lazy sml also by saying:
2498 :    
2499 :     foo.sml (with:parser.lazy-keyword=true)
2500 :     foo.sml (with:parser.lazy-keyword)
2501 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2502 :     foo.sml (with:(name:parser.lazy-keyword))

2854 :     Description:
2855 :    
2856 :     Changed the interface of structures Timer and Unix to match the most
2857 :     recent Basis spec.
2858 :    
2859 :     In the case of Unix there still seems to be an open/weird issue:
2860 :    
2861 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2862 :     fresh streams whenever they are called -- as opposed to have them
2863 :     return the same stream every time. This design is supposed to
2864 :     prevent space leaks caused by proc values hanging on to streams.
2865 :    
2866 :     The reap function, on the other hand, is supposed to close the
2867 :     streams. This cannot be done without having a handle on the
2868 :     stream in proc after all...
2869 :    
2870 :     I took the liberty to implement the following stopgap solution:
2871 :    
2872 :     The proc value hangs on to the most recently created stream(s).
2873 :     Reap closes those. If either or both of the two streams hadn't
2874 :     been created at all yet, then reap will close the corresponding
2875 :     file descriptors directly.
2876 :    
2877 :     PS: I don't understand the original space leak argument anymore. If
2878 :     a proc hangs on to the imperative stream, then I/O operations on those
2879 :     will advance the state of the cached stream and avoid the space leak.

2893 :     Description:
2894 :    
2895 :     CM now ignores (but still accepts) the "owner" information in group
2896 :     descriptions. The owner of a group is its next enclosing
2897 :     library. Each group must have a unique owner. (There is a virtual
2898 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2899 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2900 :     and CM would check that such a declaration is correct. The new scheme
2901 :     is to have CM check that for each group there is precisely one owning
2902 :     library.
2903 :    
2904 :     The advantage of the new scheme is that the programmer no longer needs
2905 :     to maintain the somewhat annoying owner information. The downside is
2906 :     that CM cannot enforce the ownership rule across multiple runs of
2907 :     CM.make. Fortunately, enclosing the same group in two different
2908 :     libraries A and B which are not part of the same program does not
2909 :     cause real problems.

2952 :     Description:
2953 :    
2954 :     Added previously missing support for many socket-related functions
2955 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
2956 :     for the voluminous patch!
2957 :    
2958 :     (I have not tested this patch under win32 yet.)
2959 :    
2960 : mblume 1490 Here is David's e-mail:
2961 :    
2962 :     Hi,
2963 :    
2964 :     Attached to this email you find a diff against sml/nj 110.45
2965 :     that will enable socket support under Windows.
2966 :    
2967 :     To apply the patch (using unix or cygwin)
2968 :     1) gunzip runtime.diff.gz
2969 :     2) "cd" into "src/runtime" in the source tree of a fresh
2970 :     110.45 installation.
2971 :     3) patch -p 1 < [your/path/to]runtime.diff
2972 :    
2973 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2974 :     I only ran a few tests for basic socket client functionality
2975 :     (which worked fine). Especially the functions that use ioctl
2976 : mblume 1490 are not tested at all and might not work (see below).
2977 :    
2978 :     I implemented this since we want to move to a newer version of sml/nj
2979 :     but need socket support in order to use it. This is the first time I
2980 :     even had a look at the sml/nj source, so please review my changes
2981 :     before making this part of the distribution! Here are a few issues
2982 : blume 2155 that I think might be better for someone to solve who is more
2983 : mblume 1490 familiar with the sml/nj source (and socket programming):
2984 :    
2985 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2986 :     exception since I could not figure out what the windows equivalent
2987 :     of these functions is
2988 :    
2989 :     - In sockets-osdep.h there are a some #include statements that are
2990 :     only used in a few files that include sockets-osdep.h
2991 :    
2992 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2993 :     does not process its return value since I don't know how to
2994 :     report an error upwards.
2995 :    
2996 :     - It would probably be good to have a call to WSACleanup() when
2997 : blume 2155 the library is unloaded (if there is such a possibility).
2998 : mblume 1490 Otherwise I think Windows will take care of this automatically
2999 :     when the process finishes.
3000 :    
3001 :     - I used ioctlsocket() as a replacement for ioctl() but I have
3002 :     no idea if that is actually the proper replacement on Windows.
3003 :    
3004 :     - All these issues are marked in the code by "FIXME" comments.
3005 :    
3006 : blume 2155 We use sml/nj extensively in our products and are quite happy
3007 :     with it. I hope this contribution will help you.
3008 : mblume 1490
3009 :     Keep up the good work!

3093 :    
3094 : blume 2155 does not work on Windows unless we explicitly export symbols

3232 :     Description:
3233 :    
3234 :     I modified the read-eval-print loop so that the autoloader gets
3235 :     invoked whenever the prettyprinter tries to look up a symbol that
3236 :     is not currently defined in the toplevel environment but which
3237 :     appears in CM's autoload registry. As a result, we see far fewer of
3238 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3239 :    
3240 :     In addition to this I tried to clean up some pieces of the Basis
3241 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3242 :     instances of these ?.Foo.Bar.xxx names from being printed.
3243 :    
3244 :     The mechanism that picks names for types still needs some work, though.
3245 :     (Right now it seems that if there is a type A.t which is defined to
3246 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3247 :     "?.B.u" although the perhaps more sensible solution would be to use
3248 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3249 :     a chain of DEFtycs not farther than there are corresponding toplevel
3250 :     names in the current environment.)

3256 :     Description:

3258 :     Another installer tweak: All the ML code for the installer is now
3259 :     compiled during CMB.make and put into a little library called
3260 :     $smlnj/installer.cm. The installation then simply invokes
3261 :    
3262 :     sml -m $smlnj/installer.cm
3263 :

3292 :     1. Fixed SOCKET API and implementation to match Basis spec.
3293 :     This required changing the internal representation of sockets to one
3294 :     that remembers (for each socket file descriptor) whether it is currently
3295 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3296 :     call is made only if the state actually needs to change).
3297 :    
3298 :     2. OS-specific details of sockets were moved into separate files, thus
3299 :     making it possible to unify the bulk of the socket implementations
3300 :     between Unix and Win32.
3301 :    
3302 :     3. CML's socket API changed accordingly.
3303 :     (Note that we need to remove non-blocking functions from this API
3304 :     since they are redundant in the case of CML!)
3305 :    
3306 :     4. CML's socket implementation now makes use of non-blocking functions
3307 :     provided by Basis, thus removing all OS-dependent code from this part
3308 :     of CML.
3309 :    
3310 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3352 :    
3353 :     1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as

3356 :

3422 :     Tag: blume-20030909-installer
3423 :     Description:
3424 :    
3425 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3426 :     Modified config/install.bat to take advantage of it. Also modified
3427 :     config/install.sh (and called it config/new-install.sh) to take advantage
3428 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3429 :     independent.)
3430 :    
3431 :     The installer can now install everything under Win32
3432 :     as well as under *nix as long as it compiles.
3433 :    
3434 :     Other changes:
3435 :    
3436 :     - made CML compile again under Win32
3437 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3438 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3439 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3440 :     same as type int; under Win32 it isn't
3441 :     - fixed some slice-related problems in the win32-specific parts of CML
3442 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3443 :     (under Win32, the volume name is case-insensitive, and the
3444 :     OS.Path code compares volume names for equality)

3454 :     CM depends on it. (CM otherwise goes into an infinite loop in certain

3461 : mblume 1350 Description:
3462 :    
3463 :     1. Changed interface to vectors and arrays in Basis to match
3464 :     (draft) Basis spec.
3465 :     2. Added signatures and implementations of slices according to
3466 :     Basis spec.
3467 :     3. Edited source code throughout the system to make it compile again
3468 :     under 1. and 2. (In some cases code had to be added to have it
3469 :     match the new signatures.)
3470 :     4. MLRISC should be backward-compatible: the copies of the originals
3471 :     of files that needed to change under 3. were retained, the .cm files
3472 :     check the compiler version number and use old versions when
3473 :     appropriate.
3474 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3475 :     dirstream -> string option (in accordance with Basis spec).
3476 :     6. When generating code that counts lines, ml-lex used function
3477 :     CharVector.foldli, taking advantage of its old interface.
3478 :     This has been replaced with the corresponding code from
3479 :     CharVectorSlice. (html-lex must be re-lexed!)
3480 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3481 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3482 :     8. Removed temporary additions (fromInternal, toInternal) from the
3483 :     (now obsolete) IntInf in smlnj-lib/Util.
3484 :     9. Cleaned up structure Byte.
3485 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3486 :     Cleaned/corrected implementation of Date.
3487 :     (Still need to check for correctness; implement better canonicalizeDate.)
3488 :     11. Added "scan" to signature IEEE_REAL.
3489 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3490 :     mod and rem when second operand is 2 (for parity checks).]
3491 :     13. Changed representation of type Time.time, using a single IntInf.int
3492 :     value counting microseconds. This considerably simplified the
3493 :     implementation of structure Time. We now support negative time
3494 :     values; scan and fromString handle signs.
3495 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3496 :     ArraySlice).

3501 :     Tag: blume-20030828-intinf
3502 :     Description:
3503 :    
3504 :     This is a major update which comes with a version number bump
3505 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3506 :     and an implementation of IntInf in the Basis.
3507 :    
3508 :     There are a fairly large number of related changes and updates throughout
3509 :     the system:
3510 :    
3511 :     Basis:
3512 :     - Implemented IntInf.
3513 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3514 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3515 : mblume 1347 - Added FixedInt as a synonym for Int32.
3516 :    
3517 :     compiler:
3518 :     * Added support for a built-in intinf type.
3519 :     - literals
3520 :     - pattern matching
3521 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3522 :     - overloading on literals and operations
3523 :    
3524 :     This required adding a primitive type intinf, some additional
3525 :     primops, and implementations for several non-trivial intinf
3526 :     operations in Core. (The intinf type is completely abstract
3527 :     to the compiler; all operations get delegated back to the Core.)
3528 :    
3529 :     * Intinf equality is handled by polyequal. However, the compiler
3530 :     does not print its usual warning in this case (since polyequal
3531 :     is the right thing to do there).
3532 :    
3533 :     * Improved the organization of structure InlineT.
3534 :    
3535 :     * A word about conversion primops:
3536 :     If conversions involving intinf do not cancel out during
3537 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3538 : mblume 1347 Since all core access must be resolved already during the FLINT
3539 :     translate phase, it would be too late a the time of CPS contract
3540 : mblume 1348 to add new Core calls. For this reason, conversion primops
3541 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3542 :     they are supposed to convert, and 2. the Core function that
3543 :     can help with this conversion if necessary. If CPS contract
3544 : mblume 1348 eliminates a primop, then the associated Core function becomes
3545 :     dead and goes away. Intinf conversion primops that do not get
3546 :     eliminated by CPS contract get rewritten into calls of their
3547 :     core functions by a separate, new phase.
3548 : mblume 1347
3549 :     interactive system:
3550 :     - Control.Print.intinfDepth controls max length of intinf constants
3551 :     being printed. (Analogous to Control.Print.stringDepth.)
3552 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3553 :     duplicates; replaced some of the code with code that makes better
3554 :     use of library functionality.
3555 :    
3556 :     CM:
3557 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3558 :     are no longer silent.
3559 :    
3560 :     CKIT:
3561 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3562 :     in favor of LargeInt -- which is now the same as IntInf.
3563 :     CKIT-knowledgable people should check whether this is what's
3564 :     intended and otherwise change things back to using Int32 or
3565 :     FixedInt.
3566 :    
3567 :     Throughout the code:
3568 : mblume 1348 Started using IntInf.int literals and built-in operations
3569 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3589 :     Description:
3590 :    
3591 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3592 :    
3593 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3594 :    
3595 :     This patch restores SML/NJ's ability to run under win32. There are a
3596 :     number of changes, including fixes for several bugs that had gone
3597 :     unnoticed until now:
3598 :    
3599 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3600 :     trying to run the win32 version from within cygwin.)
3601 :    
3602 :     - There are a number of simple .bat scripts that substitute for their
3603 :     corresponding Unix shell-scripts. (See below.)
3604 :    
3605 :     - The internals of ml-build have been modified slightly. The main
3606 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3607 :     using OS.Process.system, the ML process delegates this task back
3608 :     to the script. Otherwise problems arise in mixed environments such
3609 :     as Cygwin where scripts look and work like Unix scripts, but
3610 :     where OS.Process.system cannot run them.
3611 :    
3612 :     - In CM, the srcpath pickler used native pathname syntax -- which
3613 :     is incorrect in the case of cross-compilation. The new pickle format
3614 :     is independent of platform-specific naming conventions.
3615 :    
3616 :     - Path configuration files (such as lib/pathconfig) can now choose
3617 :     between native and standard syntax. Placing a line of the form
3618 :    
3619 :     standard!
3620 :    
3621 :     into the file causes all subsequent paths to be interpreted using
3622 :     CM standard pathname syntax (= Unix conventions); a line
3623 :    
3624 :     native!
3625 :    
3626 :     switches back to native style. This was needed so that
3627 :     path config files can be written portably, see src/system/pathconfig.
3628 :    
3629 :     - Runtime system:
3630 :    
3631 :     - win32-filesys.c: get_file_time and set_file_time now
3632 :     access modification time, not creation time.
3633 :    
3634 :     - I/O code made aware of new array representation.
3635 :    
3636 :     - Bug fixes in X86.prim.masm.
3637 :    
3638 :     - src/system/makeml made aware of win32. (For use under cygwin
3639 :     and other Unix-environments for windows.)
3640 :    
3641 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3642 :     which caused BinIO.inputAll to fail consistently.
3643 :    
3644 :     .bat scripts:
3645 :    
3646 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3647 :    
3648 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3649 :     applications (sml, ml-yacc, ml-lex).
3650 :     - ml-build.bat: analogous to ml-build.
3651 :     - config\install.bat: Analogous to config/install.sh. This requires
3652 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3653 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3654 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3655 :     and the bootfile hierarchy must have been unpacked under
3656 :     sml.boot.x86-win32.
3657 :     The script is very primitive and does a poor job at error checking.
3658 :     It only installs the base system, ml-lex, and ml-yacc. No other
3659 :     libraries are being installed (i.e., you get only those that
3660 :     are part of the compiler.)
3661 :     - link-sml.bat: analogous to .link-sml, but not currently used
3662 :    
3663 :     Unrelated bug fixes:
3664 :    
3665 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3666 :     types.
3667 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3668 :     otherwise.)

3691 :     Tag: blume-20030517-complete
3692 :     Description:
3693 :    
3694 :     Two changes:
3695 :    
3696 :     1. Added a flag for controlling whether non-exhaustive bindings will
3697 :     be treated as errors (default is false).
3698 :     2. Cleaned up the *entire* source tree so that CMB.make goes through
3699 :     without a single non-exhaustive match- or bind warning.

3705 :     Description:
3706 :    
3707 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3708 :    
3709 :     This mainly affects the quality of error messages. However, some
3710 :     of the code is now more straightforward than before. (Treatment of
3711 :     the above four constructs in translate.sml is much simpler than
3712 :     the "macro-expansion" that was going on before. Plus, the mach-
3713 :     compiler no longer gets invoked just to be able to compile an
3714 :     if-expression.)
3715 :    
3716 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3717 :     interactive loop.

3723 :     Description:
3724 :    
3725 : blume 2155 Ported the runtime system to cygwin, which uses the unix
3726 : allenleung 1327 x86-unix bin files. Missing/buggy features:
3727 :    
3728 : blume 2155 o getnetbyname, getnetbyaddr: these functions seem to be missing in
3729 : allenleung 1327 the Cygwin library.
3730 :     o Ctrl-C handling may be flaky.
3731 :     o Windows system calls and Windows I/O are not supported.
3732 :    
3733 :     A new set of binfiles is located at:
3734 :    
3735 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3736 :    
3737 :     This is only needed for bootstrapping the cygwin version of smlnj.
3738 :     Other x86 versions can use the existing binfiles.

3767 :     spilled. (Because of this bug, e.g., nucleic stopped compiling between
3768 :     110.37 and 110.38.)
3769 :     There was another set of potential problems related to the handling of
3770 :     MLRISC annotations (but those did not yet cause real problems, apparently).

3893 :    
3894 :     Another small change is that ppDec tries to give more information
3895 :     than just "<sig>" in the case of functors. However, this code is
3896 :     broken in some mysterious way if the functor's body's signature
3897 :     has not been declared by ascription but gets inferred from the

3998 :    
3999 :     0. John Reppy made several modifications to the SML/NJ library.
4000 :     In particular, there is a shiny new controls-lib.cm.
4001 :    
4002 :     1. Pushed new controls interface through compiler so that everything
4003 :     compiles again.
4004 :    
4005 :     2. Added FormatComb and FORMAT_COMB to the CML version of the

4007 :    
4008 :     3. Modified init scripts because XXX_DEFAULT environment variables

4017 :     Description:
4018 :    
4019 :     All pseudo-ops emitted before the first segment declaration
4020 :     such as TEXT, DATA, and BSS directives are assumed to be global
4021 :     declarations and are emitted first in the assembly file. This is
4022 :     useful in a number of situations where one has pseudo-ops that are not
4023 :     specific to any segment, and also works around the constraint that one
4024 :     cannot have client pseudo-ops in the TEXT segment.
4025 :    
4026 :     Because no segment is associated with these declarations it is
4027 :     an error to allocate any space or objects before the first segment
4028 :     directive and an exception will be raised. However, we cannot make
4029 :     this check for client pseudo-ops.
4030 :    
4031 :     These top level declarations are a field in the CFG graph_info.
4032 :     In theory you can continue to add to this field after the CFG has been

4056 :     Description:
4057 :    
4058 :     Applied the following bugfix provided by Emden Gansner:
4059 :    
4060 :     Output is corrupted when outputSubstr is used rather than output.
4061 :    
4062 : blume 2155 The problem occurs when a substring
4063 : blume 1189
4064 :     ss = (s, dataStart, dataLen)
4065 :    
4066 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
4067 :     avail bytes of s, starting at index dataStart, are copied into the
4068 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
4069 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
4070 :     starting this copy at index dataStart+avail in s, the current code
4071 : blume 1189 starts the copy at index avail.
4072 :    
4073 :     Fix:
4074 :     In text-io-fn.sml, change line 695 from
4075 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
4076 : blume 2155 to

4097 :     directly where appropriate.
4098 :

4101 :     replaced with cheaper shifts and masks). However, this sort of thing
4102 :     ought to be done earlier, e.g., within the CPS optimizer so that
4103 :     all architectures benefit from it.
4104 :    
4105 :     The compiler compiles to a fixed point, but changes might be somewhat
4106 :     fragile nevertheless. Please, report any strange things that you might
4107 :     see wrt. div/mod/quot/rem...

4113 :     Description:
4114 :    
4115 :     Fixed my broken div/mod logic. Unfortunately, this means that the
4116 :     inline code for div/mod now has one more comparison than before.
4117 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
4118 :     The problem was with quotient = 0, because that alone does not tell
4119 :     us which way the rounding went. One then has to look at whether
4120 :     remainder and divisor have the same sign... :(
4121 :    
4122 :     Anyway, I replaced the bootfiles with fresh ones...

4128 :     Description:
4129 :    
4130 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
4131 :    
4132 :     Primops have changed. This means that the bin/boot-file formats have
4133 :     changed as well.
4134 :    
4135 :     To make sure that there is no confusion, I made a new version.
4136 :    
4137 :    
4138 :     CHANGES:
4139 :    
4140 :     * removed REMT from mltree (remainder should never overflow).
4141 :    
4142 :     * added primops to deal with divisions of all flavors to the frontend
4143 :    
4144 :     * handled these primops all the way through so they map to their respective
4145 :     MLRISC support
4146 :    
4147 :     * used these primops in the implementation of Int, Int32, Word, Word32
4148 :    
4149 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
4150 :    
4151 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
4152 :    
4153 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
4154 :     floating point
4155 :    
4156 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
4157 :     and Real (but Real.abs maps to a separate floating-point-only primop)
4158 :    
4159 :    
4160 :     TODO items:
4161 :    
4162 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
4163 :     instructions because the machine instruction encoder cannot handle
4164 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
4165 :     REM in the first place, and REM is supported by the x86 machine coder.)
4166 :    
4167 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
4168 :     selection phase. (The two can be streamlined because the hardware
4169 :     delivers both quotient and remainder at the same time anyway.)
4170 :    
4171 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
4172 :     (Currently the behavior is inconsistent both across architectures and
4173 :     wrt. the draft Basis spec.)
4174 :    
4175 :     * Word8 should eventually be handled natively, too.
4176 :    
4177 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
4178 :     as if there currently is no execution path that could trigger it in
4179 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
4180 :     hold for things like multiplication and division.)

4185 :     Tag: blume-20020327-mlrisc-divisions
4186 :     Description:
4187 :    
4188 :     Added support for all four division operations (ML's div, mod, quot,
4189 :     and rem) to MLRISC. In the course of doing so, I also rationalized
4190 :     the naming (no more annoying switch-around of DIV and QUOT), by
4191 :     parameterizing the operation by div_rounding_mode (which can be either
