801 :     Additional bug fixes included:
802 :

811 :     Description:
812 :    
813 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
814 :    
815 :     Also, changed the handling of "no core access": When translate.sml
816 :     needs access to a core exception at a time when the core has not
817 :     been set up yet (this only happens when compiling system/smlnj/init/*),
818 :     then don't bother generating the corresponding tests.
819 :    
820 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
821 :     the exception. Unfortunately, that confuses the plambda type checker.
822 :     Moreover, it does not do any good, because at runtime we don't expect
823 :     such an exception to be ever raised. (The code in system/smlnj/init/*
824 :     has to be written very carefully with this in mind!)

837 :    
838 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
839 :     with an explicit test for zero division. This should fixes several
840 :     regressions and makes it possible for downstream optimization phases
841 :     to treat these operations as "pure" when they are applied to unsigned

864 :     Date: 2007/05/23 22:30:00 CDT
865 :     Description:
866 :    
867 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
868 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
869 :    
870 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
871 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
872 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
873 :     while running CMB.make. The point is that the single symbol
874 :     NO_PLUGINS is definde in all three cases.)
875 :    
876 :     I changed the three locations within the sources that get compiled
877 :     during CMB.make where ml-yacc or ml-lex input is processed: When
878 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
879 :     is bypassed.
880 :    
881 :     When bootstrapping new versions of the compiler, there can be
882 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
883 :     are not available or otherwise not operational. In this case one can
884 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
885 :     do so, the following command should be issued at the interactive
886 :     prompt:
887 :    
888 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
889 :    
890 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
891 :     files that normally would be generated by ml-yacc and ml-lex.
892 :     (Copies of these files are in the repository.)

899 :    
900 :     2nd merge of base from primop-branch-3 into the trunk.
901 :     Additional bug fixes included:
902 :     Date.scan and Date.fromString fixed;

908 :     Description:
909 :    
910 :     Changed the installation mechanism for CM tool plugins. These are
911 :     just libaries and now get installed like ordinary libaries.
912 :    
913 :     There are now a number of new installation targets that give some
914 :     fine-grain control over what classes and suffixes are known, and what
915 :     they will map to.
916 :     See config/targets for details.
917 :    
918 :     The code that caused plugin installation as part of running a
919 :     tool's "build" script has been removed. (The build script is for
920 :     building, not for installing.)

925 :     Description:
926 :    
927 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
928 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
929 :     CM fail if a shell tool reports a non-success exit status. If
930 :     the control is set to true, then CM will press on after tool failures
931 :     in the event that the target files exist (even though they are
932 :     considered outdated). Turning the control to true can be useful for
933 :     bootstrapping.

938 :     Description:
939 :    
940 :     Merge of ml-lpt revisions for 110.64.
941 :    
942 :     The name of several ml-lpt-lib modules has changed:
943 :     Repair => AntlrRepair
944 :     StreamPos => AntlrStreamPos
945 :     ErrHandlerFn => AntlrErrHandler
946 :     EBNF => AntlrEBNF
947 :    
948 :     The ml-antlr specification format has changed: declarations such as
949 :     %tokens and nonterminal definitions can occur *multiple* times in the
950 :     same specification. The semantics are such that each new declaration
951 :     extends the previous ones. This does not apply to %start or %name,
952 :     of course.
953 :    
954 :     Importing a grammar via %import now includes *all* declarations in from
955 :     the imported grammar, except for %name, %entry, and %start. Tokens
956 :     and nonterminals can be dropped using the new %dropping clause of the
957 :     %import directive; the separate %drop and %extend have been removed.
958 :    
959 :     We now allow optional type annotations on nonterminals, using the %nonterms
960 :     directive as in ml-yacc.
961 :    
962 :     The refcell construct is now implemented using SML's regular reference
963 :     cells, so the :== and !! notation has been deprecated.
964 :    
965 :     The ml-antlr tool now does much more checking of specifications, and
966 :     its error messages have been greatly improved. Error repair for
967 :     generated parsers has been completely rewritten, and is now both
968 :     much faster and more accurate.
969 :    
970 :     ml-ulex is now more lenient with escape codes (non-SML-standard
971 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
972 :     Also, character classes may now include a "-" character at the beginning
973 :     as is standard in most other regexp tools.
974 :    
975 :     All of these changes are documented in the user guide, which has
976 :     been updated and improved with this merge.

982 :     Description:
983 :    
984 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
985 :     Significant changes in FLINT and the front end, mostly having to do
986 :     with a reorganized system for handling primops. Various bug fixes
987 :     and improvements in printing signatures.

992 :     Description:
993 :    
994 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
995 :     The ml-antlr specification format has changed: declarations such as
996 :     %tokens and nonterminal definitions can occur *multiple* times in the
997 :     same specification. The semantics are such that each new declaration
998 :     extends the previous ones. Grammar extension constructs have also
999 :     changed. We now allow type annotations on nonterminals. Finally,
1000 :     the refcell construct is now implemented using SML's regular reference
1001 :     cells, so the :== and !! notation has been deprecated. All of these
1002 :     changes will appear in the 110.64 user guide for ml-lpt.
1003 :    
1004 :     The ml-antlr tool now does much more checking of specifications, and
1005 :     its error messages have been greatly improved. There has also been
1006 :     some work on the error repair process for generated parsers, but this
1007 :     will be further improved in 110.64.

1012 :     Description:
1013 :    
1014 :     More Basis fixes: The Char.fromString (etc.) functions did not handle
1015 :     the "\uxxxx" escape sequence. There is still an outstanding bug with
1016 :     String.fromString the tail is a format escape. I added a comment to
1017 :     this effect in Basis/Implementation/string.sml.

1096 :     Description:
1097 :    
1098 :     Added preliminary support in MLRISC for Staged Allocation, a technique
1099 :     for specifying calling conventions (see
1100 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
1101 :     Initially, we plan to use this code to generate C calls for the AMD64.
1102 :    
1103 :     The staged allocation code base resides in MLRISC/staged-allocation,
1104 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

1125 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
1126 :     of the range -128 ... 127. I've changed the code so that the range
1127 :     check is disabled. Only the low order 8 bits of the immediate operand

1169 :     Description:
1170 :    
1171 :     Brought ml-lpt manual up-to-date with the code. Many minor
1172 :     improvements to the tools, and a few minor bugfixes. Prepared
1173 :     ml-lpt-lib for integration with new UTF8 structure. Changed
1174 :     the interface for creating streams in ml-ulex (we now support
1175 :     stream creation from several kinds of sources). Overall, the
1176 :     tools are now quite stable, and their interfaces are unlikely to
1177 :     change in a way that would break compatibility. More work,
1178 :     however, is needed in the documentation.

1183 :     Description:
1184 :    
1185 :     Implemented library installer. Moved CM plugin code for
1186 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
1187 :     their respective trees. Implemented CM plugin for ml-ulex
1188 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
1189 :     and ml-antlr.
1190 :    
1191 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
1192 :     CM tools. (It turns out to be too messy to do otherwise because
1193 :     there is too much code that during installation relies on the presence
1194 :     of these tools -- resulting in a tricky ordering problem.)

1199 :     Description:
1200 :    
1201 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
1202 :     Modified CM's startup code to use shiftArgs as it processes
1203 :     command line arguments. This way, the init code in each .sml-file
1204 :     or library that is mentioned at the top level will see only
1205 :     those arguments that have not yet been processed at this point.
1206 :     In other words, the init code can "seize control" and process the
1207 :     remaining command line.

1274 :     Description:
1275 :    
1276 :     Added code to CM's "standard shell tool" implementation which
1277 :     causes it to tolerate (with a warning) the situation where the shell
1278 :     command fails (e.g., due to the shell command's non-existence)
1279 :     as long as all target files exist.
1280 :    
1281 :     This makes it possible to, e.g., build ml-yacc from sources even if
1282 :     svn checkout messed up the time stamps on files in such a way that
1283 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
1284 :     be needed to re-process yacc.grm, but obviously it might not yet be
1285 :     available at that time.)

1292 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and

1294 :     in the SML Basis specification too.

1324 :     Tag: release-110.60
1325 :     Description:
1326 :    
1327 :     New working release (110.60). NEW BOOTFILES!
1328 :    
1329 :     This is the first subversion-hosted release. There are also changes
1330 :     to the directory layout. Here is a table:
1331 :    
1332 :     (All pathnames are relative to the SML/NJ "root" directory.)
1333 :    
1334 :     config -> config
1335 :    
1336 :     src/cm -> base/cm
1337 :     src/compiler -> base/compiler
1338 :     src/runtime -> base/runtime
1339 :     src/system -> base/system
1340 :    
1341 :     src/cm/pgraph -> pgraph
1342 :    
1343 :     src/READMES -> base/READMES
1344 :     src/$notefile -> base/NOTES/$notefile
1345 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1346 :     MACOSXINSTALL WININSTALL
1347 :    
1348 :     src/smlnj-lib -> smlnj-lib
1349 :     src/MLRISC -> MLRISC
1350 :     ckit -> ckit
1351 :     src/cml -> cml
1352 :     src/eXene -> eXene
1353 :     src/heap2asm -> heap2asm
1354 :     src/lexgen -> lexgen
1355 :     src/ml-burg -> ml-burg
1356 :     src/ml-lex -> ml-lex
1357 :     src/ml-yacc -> ml-yacc
1358 :     src/ml-nlffi-lib -> nlffi/lib
1359 :     src/ml-nlffigen -> nlffi/gen
1360 :     src/smlnj-c -> smlnj-c
1361 :     src/tools/TraceDebugProf -> trace-debug-profile
1362 :    
1363 :     In addition, there is also a new
1364 :    
1365 :     ml-lpt
1366 :    
1367 :     directory containing two new program generator tools: ml-ulex and
1368 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1369 :     LL(k) parser generator). These tools are currently "beta-quality"
1370 :    
1371 :     The latest versios of the sources can now be obtained anonymously
1372 :     via subversion. For this, it is useful to first check out
1373 :    
1374 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1375 :    
1376 :     and put the resulting directory on your shell's PATH. This provides
1377 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
1378 :     and refresh-all.sh.
1379 :    
1380 :     To create a freshly checked-out copy of the sources, do
1381 :    
1382 :     checkout-all.sh [dir]
1383 :    
1384 :     where dir is the optional SML/NJ root directory (default is ".").
1385 :    
1386 :     This creates the above directory layout. Each subdirectory of
1387 :     the root is under individual subversion control. The stat-all.sh
1388 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
1389 :     each of these subtrees.

1392 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
1393 : blume 2155 Date: 2006/11/02 12:20:00 CST
1394 :     Description:
1395 :    
1396 :     Reorganized directory layout.
1397 :    
1398 :     This is a temporary solution, more reorganization is to come.
1399 :    
1400 :     The basic idea is to have a number of toplevel trees, each corresponding
1401 :     to a well-defined part of the overall system. Each part can be
1402 :     maintained individually, even in separate source repositories,
1403 :     although currently we still serve everything out of the main
1404 :     smlnj-gforge tree.
1405 :    
1406 :     Installer and and scripts have been updated to reflect the new
1407 :     layout. The installer (base/src/system/smlnj/installer) is now
1408 :     "scriptable" to avoid burning too much knowledge about the
1409 :     layout into SML source code. The main script used by the installer
1410 :     is in config/actions.
1411 :    
1412 :     The main change is that many of the subdirectories of what used to
1413 :     be known as "src" have moved to the toplevel. The "src" directory
1414 :     itself has moved down into a subtree called "base". (We may eventually
1415 :     get rid of the extra level of indirection represented by "src".)
1416 :    
1417 :     The layout is now as follows:
1418 :    
1419 :     toplevel tree name | default repository
1420 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1421 :     -------------------+----------------------------------------------------
1422 :     config | $gf/config/trunk
1423 :     |
1424 :     base | $gf/sml/trunk
1425 :     |
1426 :     smlnj-lib | $gf/smlnj-lib/trunk
1427 :     MLRISC | $gf/MLRISC/trunk
1428 :     |
1429 :     ml-yacc | $gf/ml-yacc/trunk
1430 :     ml-lex | $gf/ml-lex/trunk
1431 :     ml-burg | $gf/ml-burg/trunk
1432 :     lexgen | $gf/lexgen/trunk
1433 :     heap2asm | $gf/heap2asm/trunk
1434 :     |
1435 :     cml | $gf/cml/trunk
1436 :     eXene | $gf/eXene/trunk
1437 :     ckit | $gf/ckit/trunk
1438 :     nlffi | $gf/nlffi/trunk
1439 :     |
1440 :     smlnj-c | $gf/smlnj-c/trunk
1441 :    
1442 :     In $gf/admin there are a few useful shell scripts for checking out
1443 :     and maintaining the entire collection of trees:
1444 :    
1445 :     admin/checkout-all.sh [dir]
1446 :     -- optionally creates dir and checks out all trees from their
1447 :     default repositories; if dir is missing, checkout into .
1448 :     admin/refresh-all.sh [dir]
1449 :     -- looks at all trees (from the above list) in dir (default: .)
1450 :     and runs "svn update" if the tree exists and is under
1451 :     subversion control;
1452 :     non-existing or non-subversion trees are skipped
1453 :     admin/stat-all.sh [dir]
1454 :     -- like refresh-all.sh, but runs "svn stat" instead

1602 :     Hooked code for Darwin-specific Intel ABI into main compiler.
1603 :     (This is a temporary solution which relies on the fact that the
1604 :     compiler itself does not use NLFFI. Eventually we need to divorce

1634 :     Description:
1635 :    
1636 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1637 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1638 : blume 2155 at the time when config/preloads is processed, the library has to
1639 : mblume 1878 be referred to by another name. In 110.57 this would be
1640 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1641 :     to be valid as well.)

1698 :    
1699 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1700 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1701 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1702 :     it. Instead, it has the status of "user code", so it should use
1703 :     $/basis.cm to refer to the Basis library. (At least that's true for
1704 :     the purpose of bootstrapping the previous change. In the future it
1705 :     might make sense to have versiontool.cm refer to
1706 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1707 :     compiler itself uses.)
1708 :    
1709 :     Also patched src/system/testml to have it activate those extra anchor
1710 :     bindings in config/extrapathconfig.

1715 :     Tag: blume-22051115-libraries
1716 :     Description:
1717 :    
1718 :     This change affects the way the following libraries are tied into
1719 :     the system:
1720 :    
1721 :     $/basis.cm
1722 :     $/smlnj-lib.cm
1723 :     $/pp-lib.cm
1724 :     $/controls-lib.cm
1725 :     $/html-lib.cm
1726 :     $/ml-yacc-lib.cm
1727 :    
1728 :     These libraries are now internally (as seen from the source code
1729 :     of the implementation itself) known by the following names:
1730 :    
1731 :     $smlnj/basis/basis.cm
1732 :     $smlnj/smlnj-lib/smlnj-lib.cm
1733 :     $smlnj/smlnj-lib/pp-lib.cm
1734 :     $smlnj/smlnj-lib/controls-lib.cm
1735 :     $smlnj/smlnj-lib/html-lib.cm
1736 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1737 :    
1738 :     This makes it possible to work with code that requires different
1739 :     versions of these libraries, and which refers to these libraries using
1740 :     their "default" names (i.e., the first set of names above). In other
1741 :     words, one can un-define or re-define those default names without
1742 :     compromising the proper functioning of the compiler itself.
1743 :    
1744 :     A similar procedure had already been performed for several of the
1745 :     MLRISC libraries that are linked into the compiler. I did some
1746 :     cleanup on this code.
1747 :    
1748 :     A new file in the config directory (named extrapathconfig) is
1749 :     responsible for setting up path anchors that the compiler itself does
1750 :     not need, but that are typically required by user code.

1930 :     Description:
1931 :    
1932 :     Added mechanism for re-creating a heap file for the interactive system
1933 :     after configuration variables have been changed.
1934 :    
1935 :     CM.redump_heap : string -> unit
1936 :    
1937 :     This is much like SMLofNJ.exportML, but starting from the resulting
1938 : blume 2155 heap does not return to the caller of CM.redump_heap but
1939 : mblume 1792 restarts the interactive system from scratch. The original call of
1940 :     CM.redump_heap does not return but ends the interactive session.
1941 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1942 :    
1943 :     Internally, redump_heap winds the dynamic execution context back to
1944 :     the point where the original heap image was created and re-executes
1945 :     the heap image generation code in the boot code.

2061 :     Tag: blume-20050114-heap2exec
2062 :     Description:
2063 :    
2064 :     Implemented new (but still experimental) heap2exec facility. This is
2065 :     tested under Mac OS X and should work under Linux (will test shortly).
2066 :     It will probably also work on the Sparc (will test some time later).
2067 :    
2068 :     - removed old "HACKED_STANDALONE" hack from runtime
2069 :    
2070 :     To be able to test this, uncomment the request for "heap2asm" in
2071 :     config/targets prior to installation. (Notice that this is different
2072 :     from "heap2exec" mentioned below. Not a typo.)
2073 :    
2074 :     To perform an actual test, run the command
2075 :    
2076 :     $ bin/heap2exec heapfile execfile
2077 :    
2078 :     (You can put heap2exec on your shell's path.)
2079 :    
2080 :     For example, run
2081 :    
2082 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
2083 :    
2084 :     This will create a standalone executable called "mly" which you can
2085 :     then invoke directly as a command.

2109 :     * Implemented access to signed and unsigned long long data in NLFFI.
2110 :     (The parameter-passing part of the picture has not complete. But
2111 :     data structure access seems to work.)
2112 :    
2113 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
2114 :     (On the Mac, it is big-endian. And that's currently our only
2115 :     PPC platform.)

2230 :     Tag: blume-20041124-position
2231 :     Description:
2232 :    
2233 :     The compiler can now be compiled in a mode that makes structure Position
2234 :     equal to Int64. The default, however, is unchanged (Position = Int31)
2235 :     for the time being.
2236 :    
2237 :     To enable 64-bit positions, use the following procedure:
2238 :    
2239 :     1. Start sml
2240 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
2241 :     3. Type
2242 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
2243 :     4. Run CMB.make() as usual.
2244 :    
2245 :     This is barely tested. The only test so far was a little SML program
2246 :     counting the number of characters in an 8-gigabyte file by
2247 :     reading it character-by-character. That test was successful.
2248 :    
2249 :     In support of 64-bit positions, a number of new functions have been
2250 :     added to the runtime system.

2295 :    
2296 :     - In a previous commit, fixed a minor issue with how polyequal is being
2297 :     translated. In particular, the code now "looks through" abstractions.
2298 :     This results in slightly fewer polyEqual warnings and hopefully slightly
2299 :     more efficient code. Important examples for where this matters are
2300 :     the new int64 and word64 types.

2318 :     conversions from and to LargeWord. (Eventually these need to be identities,
2319 :     but for the time being they don't even make sense because LargeWord is
2320 :     32-bit wide.)
2321 :    
2322 :     Also started to add similar support for Int64, but major pieces of that
2323 :     are still missing.

2328 :     Tag: blume-20041111-word64
2329 :     Description:
2330 :    
2331 :     Structure Word64 is now (almost) complete, word literals and patterns
2332 :     seem to work. There are a few odd pieces missing. In particular,
2333 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2334 :     at the moment.
2335 :    
2336 :     Making Word64 official would mean that LargeWord becomes Word64. But
2337 :     this requires extreme care because most word-word conversions have to
2338 :     go through LargeWord, so making a mistake means loss of efficiency or
2339 :     worse. Eventually there will be a solution similar to (but actually
2340 :     simpler than) what I did with IntInf.

2376 :     - Default contents of config/srcarchiveurl uses $VERSION and
2377 :     normally does not have to be edited to reflect a version change.
2378 :    
2379 :     (As a result, a version change can be done by just editing
2380 :     config/version, the rest is now automatic.)

2420 :     Tag: blume-20041020-standalone-backtrace
2421 :     Description:
2422 :    
2423 :     Added a mechanism for getting back-trace information from standalone
2424 :     programs. Here is how it works:
2425 :    
2426 :     1. The part of the program from which you want to get backtrace
2427 :     information (usually the whole program) should be wrapped with
2428 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
2429 :     main program could be modified from something like
2430 :    
2431 :     fun main (pgm, args) = ...
2432 :    
2433 :     to
2434 :    
2435 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2436 :    
2437 :     2. To be able to access BackTrace.monitor, you have to add
2438 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
2439 :     main function.
2440 :    
2441 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2442 :     CM might have created in the past for your project).
2443 :    
2444 :     4. Build the system using this command line:
2445 :    
2446 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2447 :     myprog.cm MyProg.main myprog
2448 :    
2449 :     instead of the usual
2450 :    
2451 :     ml-build myprog.cm MyProg.main myprog
2452 :    
2453 :     I changed a library name:
2454 :    
2455 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2456 :    
2457 :     New libraries:
2458 :    
2459 :     $smlnj-tdp/back-trace.cm
2460 :     -- when loaded causes the back-trace plugin to be installed
2461 :     $smlnj-tdp/coverage.cm
2462 :     -- when loaded causes the coverage plugin to be installed

2478 :     Description:
2479 :    
2480 :     * Test coverage tool added!
2481 :     * Further reorganization of tracing-, debugging-, and profiling support:
2482 :    
2483 :     - moved original BTImp -- now called BackTrace -- into a separate
2484 :     library called $/trace-debug-profile.cm
2485 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2486 :     - only the instrumentation mechanism is now left in the compiler proper
2487 :     - BackTrace module is a plugin which is NOT plugged in by default
2488 :     - Coverage module is another such plugin
2489 :    
2490 :     To get the benefits of any of these plugin modules, the code in
2491 :     question must be compiled with tdp instrumentation turned on. This
2492 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2493 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2494 :    
2495 :     Plugins are selected at link time. (Pre-compiled instrumented code
2496 :     can be re-loaded with different plugins in effect.) When an
2497 :     instrumented module is linked, whatever plugins are at that time
2498 :     enabled will come into effect for that module.
2499 :    
2500 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2501 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2502 :     To enable the coverage plugin, load the same library and invoke
2503 :     Coverage.install().
2504 :    
2505 :     Back-traces are generated automatically on uncaught exceptions and
2506 :     when the code in question explicitly invokes BackTrace.trigger().
2507 :    
2508 :     Coverage (and execution frequency-) information must be queried
2509 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2524 :     Description:
2525 :    
2526 :     Some rationalization of names:
2527 :    
2528 :     structure BTrace -> structure TDPInstrument
2529 :     etc.
2530 :    
2531 :     This is is preparation of using the original back-trace
2532 :     instrumentation for other purposes. "TDP" stands for
2533 :     Trace/Debug/Profile.
2534 :    
2535 :     The control flag controlling whether instrumentation is on or off is now
2536 :     registered under a different name, so instead of running sml as
2537 :    
2538 :     sml -Cinstrument.btrace-mode=true
2539 :    
2540 :     one has to say
2541 :

2558 :     Description:
2559 :    
2560 :     Fixed handling of keywords in .cm files: After seeing "is" the lexer
2561 :     treats subsequent occurrences of "group", "library", "source", "is",
2562 :     "*", and "-" as ordinary identifiers rather than keywords.
2563 :    
2564 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool
2565 :     is supposed to accept a tool argument called "source", but this did
2566 :     not work because of the clash with the keyword.

2602 :     CMB.make, the release number gets bumped twice when slaves are

2609 :     Description:
2610 :    
2611 :     * Moved the "version" magic into its own little library under
2612 : mblume 1672 src/system/smlnj/internal. This avoids expensive reconstruction of
2613 :     a stable src/compiler/core.cm.
2614 : mblume 1639
2615 : mblume 1672 * At the same time, structure CompilerVersion is now known as
2616 :     structure SMLNJVersion.
2617 : mblume 1639
2618 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2619 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2620 :     Also, loading the versiontool does not work when rebuilding the system
2621 :     because CM is not properly initialized at that time.

2626 :     Tag: blume-20040929-autoversion
2627 :     Description:
2628 :    
2629 :     Implemented some CM magic to have
2630 :     file src/compiler/TopLevel/main/version.sml
2631 :     generated automagically.
2632 :     The version is taken from two files: config/version and config/release.
2633 :     The first is expected to contain a two-part version number such as 110.49.
2634 :     The second should contain a single number, but it may be missing.
2635 :    
2636 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2637 :     time the version tool is loaded (which is the first time you say CMB.make),
2638 :     then the tool will increment the value stored in config/release every
2639 :     time CMB.make is invoked.
2640 :    
2641 :     The binfile format is now insensitive to anything beyond the first
2642 :     two components of a version number, so bumping the release does not render
2643 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2644 :     during development without invalidating existing binfiles.
2645 :    
2646 :     In any case, every CMB.make updates the date information in version.sml.
2647 :     (This is the date that is printed in the banner.)

2660 :     Tag: blume-20040927-controls
2661 :     Description:
2662 :    
2663 :     Added two pieces of functionality to the Controls interface:
2664 :    
2665 :     1. val save'restore: 'a control -> unit -> unit
2666 :    
2667 :     grabs the current value of the control in stage 1 and restores it
2668 :     in stage 2.
2669 :    
2670 :     2. val set' : 'a control * 'a -> unit -> unit
2671 :    
2672 :     stores the given value into the control in stage 2 (i.e., delayed)
2673 :     but does all error checking in stage 1.
2674 :     (This is for string controls that need to do parse their argument --
2675 :     something that might fail. In some cases, notably in CM, one
2676 :     already knows the intended argument but wants to delay the actual
2677 :     assignment until a time when error recovery would be more difficult.)
2678 :    
2679 :     Changed the handling of controls in tool arguments to classes "sml" and
2680 :     "lazysml":
2681 :     - use Controls.save'restore as a more robust way of restoring the
2682 :     old value (in particular: without having to re-parse the string)
2683 :     - use controls to handle the "overload" keyword in the init group
2684 :     (I believe this change actually fixes a long-standing obscure bug.)

2689 :     Tag: blume-20040927-lazysml
2690 :     Description:
2691 :    
2692 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2693 :     difference to "sml" is that compilation is done with Control.lazysml
2694 :     set to true. A source of class "lazysml" is automatically recognized
2695 :     by a file name suffix of ".lml".
2696 :    
2697 :     In addition to the above feature, the original class "sml" now also
2698 :     supports a tool argument "lazy" which has the same effect. As a
2699 :     result, the following three lines are equivalent:
2700 :    
2701 :     foo.sml : lazysml
2702 :     foo.sml : sml (lazy)
2703 :     foo.sml (lazy)
2704 :    
2705 :     The setting goes into effect both during parsing and during
2706 :     compilation. The original setting is restored right after parsing and
2707 :     after compilation, respectively.
2708 :    
2709 :     In addition to all the above, there is also a general mechanism to set
2710 :     ANY of the "controls" that are available at the command line via
2711 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2712 :     apply as well. (In fact, "lazy" is implemented as a special case of
2713 :     the general mechanism.)
2714 :    
2715 :     The .cm file syntax uses a new keyword tool argument called "with".
2716 :     There are several ways of indicating the desired settings:
2717 :    
2718 :     foo.sml (with:parser.quotations=true)
2719 :     foo.sml (with:(name:parser.quotations value:true))
2720 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2721 :     foo.sml (with:(name1=value1 name2=value2 ...))
2722 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2723 :    
2724 :     etc.
2725 :    
2726 :     Another possible abbreviation is to leave out the =v or value:v part
2727 :     if the name refers to a boolean control (in which case the value is
2728 :     taken to be true). Thus, one could get lazy sml also by saying:
2729 :    
2730 :     foo.sml (with:parser.lazy-keyword=true)
2731 :     foo.sml (with:parser.lazy-keyword)
2732 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2733 :     foo.sml (with:(name:parser.lazy-keyword))

3033 :     (for PPC version where parameter area is pre-allocated)
3034 :     - added ccall_maxargspace to machspec (to implement the above)
3035 :     - made "make" commend in CM's "make" tool configurable
3036 :     - added option (default: on) for passing the name of the SML/NJ's "bin"

3038 :    
3039 :     make <options> SMLNJ_BINDIR=<dir> <target>

3085 :     Description:
3086 :    
3087 :     Changed the interface of structures Timer and Unix to match the most
3088 :     recent Basis spec.
3089 :    
3090 :     In the case of Unix there still seems to be an open/weird issue:
3091 :    
3092 :     The {text,bin}{In,Out}streamOf functions are supposed to create
3093 :     fresh streams whenever they are called -- as opposed to have them
3094 :     return the same stream every time. This design is supposed to
3095 :     prevent space leaks caused by proc values hanging on to streams.
3096 :    
3097 :     The reap function, on the other hand, is supposed to close the
3098 :     streams. This cannot be done without having a handle on the
3099 :     stream in proc after all...
3100 :    
3101 :     I took the liberty to implement the following stopgap solution:
3102 :    
3103 :     The proc value hangs on to the most recently created stream(s).
3104 :     Reap closes those. If either or both of the two streams hadn't
3105 :     been created at all yet, then reap will close the corresponding
3106 :     file descriptors directly.
3107 :    
3108 :     PS: I don't understand the original space leak argument anymore. If
3109 :     a proc hangs on to the imperative stream, then I/O operations on those
3110 :     will advance the state of the cached stream and avoid the space leak.

3123 :     Tag: blume-20040525-group-owner
3124 :     Description:
3125 :    
3126 :     CM now ignores (but still accepts) the "owner" information in group
3127 :     descriptions. The owner of a group is its next enclosing
3128 :     library. Each group must have a unique owner. (There is a virtual
3129 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
3130 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
3131 :     and CM would check that such a declaration is correct. The new scheme
3132 :     is to have CM check that for each group there is precisely one owning
3133 :     library.
3134 :    
3135 :     The advantage of the new scheme is that the programmer no longer needs
3136 :     to maintain the somewhat annoying owner information. The downside is
3137 :     that CM cannot enforce the ownership rule across multiple runs of
3138 :     CM.make. Fortunately, enclosing the same group in two different
3139 :     libraries A and B which are not part of the same program does not
3140 :     cause real problems.

3159 :     Description:
3160 :    
3161 :     Arranged for ml-build to clean up after itself a little bit better.
3162 :     The script generates a temporary SML source file and compiles it using
3163 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
3164 :     gets rid of those at the end, so they don't accumulate under .cm.
3165 :    
3166 :     This required a minor change to install.sh because the name of the

3187 :     for the voluminous patch!
3188 :    
3189 :     (I have not tested this patch under win32 yet.)
3190 :    
3191 : mblume 1490 Here is David's e-mail:
3192 :    
3193 :     Hi,
3194 :    
3195 :     Attached to this email you find a diff against sml/nj 110.45
3196 :     that will enable socket support under Windows.
3197 :    
3198 :     To apply the patch (using unix or cygwin)
3199 :     1) gunzip runtime.diff.gz
3200 :     2) "cd" into "src/runtime" in the source tree of a fresh
3201 :     110.45 installation.
3202 :     3) patch -p 1 < [your/path/to]runtime.diff
3203 :    
3204 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
3205 :     I only ran a few tests for basic socket client functionality
3206 :     (which worked fine). Especially the functions that use ioctl
3207 : mblume 1490 are not tested at all and might not work (see below).
3208 :    
3209 :     I implemented this since we want to move to a newer version of sml/nj
3210 :     but need socket support in order to use it. This is the first time I
3211 :     even had a look at the sml/nj source, so please review my changes
3212 :     before making this part of the distribution! Here are a few issues
3213 : blume 2155 that I think might be better for someone to solve who is more
3214 : mblume 1490 familiar with the sml/nj source (and socket programming):
3215 :    
3216 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
3217 :     exception since I could not figure out what the windows equivalent
3218 :     of these functions is
3219 :    
3220 :     - In sockets-osdep.h there are a some #include statements that are
3221 :     only used in a few files that include sockets-osdep.h
3222 :    
3223 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
3224 :     does not process its return value since I don't know how to
3225 :     report an error upwards.
3226 :    
3227 :     - It would probably be good to have a call to WSACleanup() when
3228 : blume 2155 the library is unloaded (if there is such a possibility).
3229 : mblume 1490 Otherwise I think Windows will take care of this automatically
3230 :     when the process finishes.
3231 :    
3232 :     - I used ioctlsocket() as a replacement for ioctl() but I have
3233 :     no idea if that is actually the proper replacement on Windows.
3234 :    
3235 :     - All these issues are marked in the code by "FIXME" comments.
3236 :    
3237 : blume 2155 We use sml/nj extensively in our products and are quite happy
3238 :     with it. I hope this contribution will help you.
3239 : mblume 1490
3240 :     Keep up the good work!

3317 :     Description:
3318 :    
3319 :     Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
3320 :     of SML/NJ. The problem is that
3321 :    
3322 :     lib = dlopen(NULL, ...)
3323 :     f = dlsym(lib, "malloc");
3324 :    
3325 : blume 2155 does not work on Windows unless we explicitly export symbols
3326 :     such as 'malloc' during linking. We fixed this by explicitly
3327 : allenleung 1468 exporting the required symbols with the magic gcc incantation:
3328 :    
3329 :     -Wl,--export-all cygwin.def
3330 :    
3331 :     where cygwin.def is a file containing all the symbols that
3332 : blume 2155 we wish to export.
3333 : allenleung 1468
3334 : blume 2155 I suspect this is a Windows problem and we'll have to
3335 :     do the same (somehow with windows compilers) when
3336 : allenleung 1468 we build the native win32 version with the system
3337 : blume 2155 calls LoadLibrary/GetProcAddress.

3407 :     Eliminated the "dont_move_libraries" directive in config/targets.
3408 :     (The mechanism was broken and could not be fixed easily. Moreover,
3409 :     there does not seem to be any reason not to move all libraries into
3410 :     lib during installation. I originally implemented this directive as a
3411 :     backward-compatibility feature when I first introduced the new CM.
3412 :     Now that things have been stable for a long time and going back to the
3413 :     old CM is not an option, there is no reason to keep it around.)

3462 :     Tag: blume-20030926-ppautoload
3463 :     Description:
3464 :    
3465 :     I modified the read-eval-print loop so that the autoloader gets
3466 :     invoked whenever the prettyprinter tries to look up a symbol that
3467 :     is not currently defined in the toplevel environment but which
3468 :     appears in CM's autoload registry. As a result, we see far fewer of
3469 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3470 :    
3471 :     In addition to this I tried to clean up some pieces of the Basis
3472 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3473 :     instances of these ?.Foo.Bar.xxx names from being printed.
3474 :    
3475 :     The mechanism that picks names for types still needs some work, though.
3476 :     (Right now it seems that if there is a type A.t which is defined to
3477 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3478 :     "?.B.u" although the perhaps more sensible solution would be to use
3479 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3480 :     a chain of DEFtycs not farther than there are corresponding toplevel
3481 :     names in the current environment.)

3487 :     Description:
3488 :    
3489 :     Another installer tweak: All the ML code for the installer is now
3490 :     compiled during CMB.make and put into a little library called
3491 :     $smlnj/installer.cm. The installation then simply invokes
3492 :    
3493 :     sml -m $smlnj/installer.cm
3494 :    
3495 :     and everything happens automagically.
3496 :    
3497 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3498 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3499 :     and BINDIR.
3500 :    
3501 :     The new scheme guarantees that the ML code responsible for the installation
3502 :     is in sync with the APIs of the main system. Also, the installer is
3503 :     somewhat faster because the installer script is precompiled.

3513 :     and CML_SOCKET in terms of SYNCHRONOUS_SOCKET. Removed superfluous

3515 :     structure.

3520 :     Tag: blume-20030924-sockets
3521 :     Description:
3522 :    
3523 :     1. Fixed SOCKET API and implementation to match Basis spec.
3524 :     This required changing the internal representation of sockets to one
3525 :     that remembers (for each socket file descriptor) whether it is currently
3526 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3527 :     call is made only if the state actually needs to change).
3528 :    
3529 :     2. OS-specific details of sockets were moved into separate files, thus
3530 :     making it possible to unify the bulk of the socket implementations
3531 :     between Unix and Win32.
3532 :    
3533 :     3. CML's socket API changed accordingly.
3534 :     (Note that we need to remove non-blocking functions from this API
3535 :     since they are redundant in the case of CML!)
3536 :    
3537 :     4. CML's socket implementation now makes use of non-blocking functions
3538 :     provided by Basis, thus removing all OS-dependent code from this part
3539 :     of CML.
3540 :    
3541 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3654 :     Description:
3655 :    
3656 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3657 :     Modified config/install.bat to take advantage of it. Also modified
3658 :     config/install.sh (and called it config/new-install.sh) to take advantage
3659 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3660 :     independent.)
3661 :    
3662 :     The installer can now install everything under Win32
3663 :     as well as under *nix as long as it compiles.
3664 :    
3665 :     Other changes:
3666 :    
3667 :     - made CML compile again under Win32
3668 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3669 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3670 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3671 :     same as type int; under Win32 it isn't
3672 :     - fixed some slice-related problems in the win32-specific parts of CML
3673 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3674 :     (under Win32, the volume name is case-insensitive, and the
3675 :     OS.Path code compares volume names for equality)

3694 :     1. Changed interface to vectors and arrays in Basis to match
3695 :     (draft) Basis spec.
3696 :     2. Added signatures and implementations of slices according to
3697 :     Basis spec.
3698 :     3. Edited source code throughout the system to make it compile again
3699 :     under 1. and 2. (In some cases code had to be added to have it
3700 :     match the new signatures.)
3701 :     4. MLRISC should be backward-compatible: the copies of the originals
3702 :     of files that needed to change under 3. were retained, the .cm files
3703 :     check the compiler version number and use old versions when
3704 :     appropriate.
3705 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3706 :     dirstream -> string option (in accordance with Basis spec).
3707 :     6. When generating code that counts lines, ml-lex used function
3708 :     CharVector.foldli, taking advantage of its old interface.
3709 :     This has been replaced with the corresponding code from
3710 :     CharVectorSlice. (html-lex must be re-lexed!)
3711 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3712 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3713 :     8. Removed temporary additions (fromInternal, toInternal) from the
3714 :     (now obsolete) IntInf in smlnj-lib/Util.
3715 :     9. Cleaned up structure Byte.
3716 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3717 :     Cleaned/corrected implementation of Date.
3718 :     (Still need to check for correctness; implement better canonicalizeDate.)
3719 :     11. Added "scan" to signature IEEE_REAL.
3720 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3721 :     mod and rem when second operand is 2 (for parity checks).]
3722 :     13. Changed representation of type Time.time, using a single IntInf.int
3723 :     value counting microseconds. This considerably simplified the
3724 :     implementation of structure Time. We now support negative time
3725 :     values; scan and fromString handle signs.
3726 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3727 :     ArraySlice).

3732 :     Tag: blume-20030828-intinf
3733 :     Description:
3734 :    
3735 :     This is a major update which comes with a version number bump
3736 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3737 :     and an implementation of IntInf in the Basis.
3738 :    
3739 :     There are a fairly large number of related changes and updates throughout
3740 :     the system:
3741 :    
3742 :     Basis:
3743 :     - Implemented IntInf.
3744 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3745 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3746 : mblume 1347 - Added FixedInt as a synonym for Int32.
3747 :    
3748 :     compiler:
3749 :     * Added support for a built-in intinf type.
3750 :     - literals
3751 :     - pattern matching
3752 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3753 :     - overloading on literals and operations
3754 :    
3755 :     This required adding a primitive type intinf, some additional
3756 :     primops, and implementations for several non-trivial intinf
3757 :     operations in Core. (The intinf type is completely abstract
3758 :     to the compiler; all operations get delegated back to the Core.)
3759 :    
3760 :     * Intinf equality is handled by polyequal. However, the compiler
3761 :     does not print its usual warning in this case (since polyequal
3762 :     is the right thing to do there).
3763 :    
3764 :     * Improved the organization of structure InlineT.
3765 :    
3766 :     * A word about conversion primops:
3767 :     If conversions involving intinf do not cancel out during
3768 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3769 : mblume 1347 Since all core access must be resolved already during the FLINT
3770 :     translate phase, it would be too late a the time of CPS contract
3771 : mblume 1348 to add new Core calls. For this reason, conversion primops
3772 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3773 :     they are supposed to convert, and 2. the Core function that
3774 :     can help with this conversion if necessary. If CPS contract
3775 : mblume 1348 eliminates a primop, then the associated Core function becomes
3776 :     dead and goes away. Intinf conversion primops that do not get
3777 :     eliminated by CPS contract get rewritten into calls of their
3778 :     core functions by a separate, new phase.
3779 : mblume 1347
3780 :     interactive system:
3781 :     - Control.Print.intinfDepth controls max length of intinf constants
3782 :     being printed. (Analogous to Control.Print.stringDepth.)
3783 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3784 :     duplicates; replaced some of the code with code that makes better
3785 :     use of library functionality.
3786 :    
3787 :     CM:
3788 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3789 :     are no longer silent.
3790 :    
3791 :     CKIT:
3792 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3793 :     in favor of LargeInt -- which is now the same as IntInf.
3794 :     CKIT-knowledgable people should check whether this is what's
3795 :     intended and otherwise change things back to using Int32 or
3796 :     FixedInt.
3797 :    
3798 :     Throughout the code:
3799 : mblume 1348 Started using IntInf.int literals and built-in operations
3800 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3807 :     Description:
3808 :    
3809 :     Merging changes from the mcz-branch development branch into trunk.
3810 :     These changes involve replacement of the emulated old prettyprinter
3811 :     interface with direct use of the SML/NJ Lib PP library, and fixing
3812 :     of a couple of bugs (895, 1186) relating to error messages. A new
3813 :     prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
3814 :     has been added.

3819 :     Tag: blume-20030811-windows
3820 :     Description:
3821 :    
3822 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3823 :    
3824 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3825 :    
3826 :     This patch restores SML/NJ's ability to run under win32. There are a
3827 :     number of changes, including fixes for several bugs that had gone
3828 :     unnoticed until now:
3829 :    
3830 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3831 :     trying to run the win32 version from within cygwin.)
3832 :    
3833 :     - There are a number of simple .bat scripts that substitute for their
3834 :     corresponding Unix shell-scripts. (See below.)
3835 :    
3836 :     - The internals of ml-build have been modified slightly. The main
3837 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3838 :     using OS.Process.system, the ML process delegates this task back
3839 :     to the script. Otherwise problems arise in mixed environments such
3840 :     as Cygwin where scripts look and work like Unix scripts, but
3841 :     where OS.Process.system cannot run them.
3842 :    
3843 :     - In CM, the srcpath pickler used native pathname syntax -- which
3844 :     is incorrect in the case of cross-compilation. The new pickle format
3845 :     is independent of platform-specific naming conventions.
3846 :    
3847 :     - Path configuration files (such as lib/pathconfig) can now choose
3848 :     between native and standard syntax. Placing a line of the form
3849 :    
3850 :     standard!
3851 :    
3852 :     into the file causes all subsequent paths to be interpreted using
3853 :     CM standard pathname syntax (= Unix conventions); a line
3854 :    
3855 :     native!
3856 :    
3857 :     switches back to native style. This was needed so that
3858 :     path config files can be written portably, see src/system/pathconfig.
3859 :    
3860 :     - Runtime system:
3861 :    
3862 :     - win32-filesys.c: get_file_time and set_file_time now
3863 :     access modification time, not creation time.
3864 :    
3865 :     - I/O code made aware of new array representation.
3866 :    
3867 :     - Bug fixes in X86.prim.masm.
3868 :    
3869 :     - src/system/makeml made aware of win32. (For use under cygwin
3870 :     and other Unix-environments for windows.)
3871 :    
3872 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3873 :     which caused BinIO.inputAll to fail consistently.
3874 :    
3875 :     .bat scripts:
3876 :    
3877 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3878 :    
3879 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3880 :     applications (sml, ml-yacc, ml-lex).
3881 :     - ml-build.bat: analogous to ml-build.
3882 :     - config\install.bat: Analogous to config/install.sh. This requires
3883 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3884 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3885 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3886 :     and the bootfile hierarchy must have been unpacked under
3887 :     sml.boot.x86-win32.
3888 :     The script is very primitive and does a poor job at error checking.
3889 :     It only installs the base system, ml-lex, and ml-yacc. No other
3890 :     libraries are being installed (i.e., you get only those that
3891 :     are part of the compiler.)
3892 :     - link-sml.bat: analogous to .link-sml, but not currently used
3893 :    
3894 :     Unrelated bug fixes:
3895 :    
3896 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3897 :     types.
3898 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3899 :     otherwise.)

3923 :     Description:
3924 :    
3925 :     Two changes:
3926 :    
3927 :     1. Added a flag for controlling whether non-exhaustive bindings will
3928 :     be treated as errors (default is false).
3929 :     2. Cleaned up the *entire* source tree so that CMB.make goes through
3930 :     without a single non-exhaustive match- or bind warning.

3936 :     Description:
3937 :    
3938 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3939 :    
3940 :     This mainly affects the quality of error messages. However, some
3941 :     of the code is now more straightforward than before. (Treatment of
3942 :     the above four constructs in translate.sml is much simpler than
3943 :     the "macro-expansion" that was going on before. Plus, the mach-
3944 :     compiler no longer gets invoked just to be able to compile an
3945 :     if-expression.)
3946 :    
3947 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3948 :     interactive loop.

3954 :     Description:
3955 :    
3956 : blume 2155 Ported the runtime system to cygwin, which uses the unix
3957 : allenleung 1327 x86-unix bin files. Missing/buggy features:
3958 :    
3959 : blume 2155 o getnetbyname, getnetbyaddr: these functions seem to be missing in
3960 : allenleung 1327 the Cygwin library.
3961 :     o Ctrl-C handling may be flaky.
3962 :     o Windows system calls and Windows I/O are not supported.
3963 :    
3964 :     A new set of binfiles is located at:
3965 :    
3966 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3967 :    
3968 :     This is only needed for bootstrapping the cygwin version of smlnj.

4010 :     This fixes the problem of CM getting confused by files that suddenly
4011 :     change their identity (e.g., by getting unlinked and recreated by some
4012 :     text editor such as vi). There might be a better/cheaper/cleaner way

4102 :     Description:
4103 :    
4104 :     Fixed a bug in translation of INLMAX (and INLMIN) for the floating-point
4105 :     case. (The sense of the isNaN test was reversed -- which made min and
4106 :     max always return their first argument.)

4120 :     Description:
4121 :    
4122 :     I back-ported my implementation of IEEEReal.fromString from the
4123 :     idlbasis-devel branch so that we can test it.
4124 :    
4125 :     Another small change is that ppDec tries to give more information
4126 :     than just "<sig>" in the case of functors. However, this code is
4127 :     broken in some mysterious way if the functor's body's signature
4128 :     has not been declared by ascription but gets inferred from the
4129 :     implementation. This needs fixing...

4136 :    
4137 :     Resurrected SMLofNJ.Internals.BTrace.mode. (It accidentally fell by
4138 :     the wayside when I switched over to using Controls everywhere.)
