895 :     Revision: 2650
896 :     Description:
897 :    
898 :     3rd merge of base from primop-branch-3 into the trunk.
899 :     Additional bug fixes included:
900 :    
901 :     * Timer.cpu_timer, etc. type printing corrected (by making
902 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
903 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
904 :     Stefan Monnier)

908 :     Date: 2007/05/31 11:40:00 CDT
909 :     Description:
910 :    
911 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
912 :    
913 :     Also, changed the handling of "no core access": When translate.sml
914 :     needs access to a core exception at a time when the core has not
915 :     been set up yet (this only happens when compiling system/smlnj/init/*),
916 :     then don't bother generating the corresponding tests.
917 :    
918 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
919 :     the exception. Unfortunately, that confuses the plambda type checker.
920 :     Moreover, it does not do any good, because at runtime we don't expect
921 :     such an exception to be ever raised. (The code in system/smlnj/init/*
922 :     has to be written very carefully with this in mind!)

933 :     Date: 2007/05/29 19:00:00 CDT
934 :     Description:
935 :    
936 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
937 :     with an explicit test for zero division. This should fixes several
938 :     regressions and makes it possible for downstream optimization phases
939 :     to treat these operations as "pure" when they are applied to unsigned
940 :     operands.

944 :     Date: 2007/05/29
945 :     Description:
946 :    
947 :     Added the new MLRISC code generator for the AMD64. This version,
948 :     in contrast to the previous one, uses SSE registers and instructions
949 :     for all floating-point computations.

954 : jhr 2613 Description:
955 :    
956 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
957 :     for bugs #1415 and #1416. We also now correctly handle format characters that
958 :     lie outside the specified set.

961 : blume 2610 Name: Matthias Blume (http://www.tti-c.org/blume/)
962 :     Date: 2007/05/23 22:30:00 CDT
963 :     Description:
964 :    
965 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
966 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
967 :    
968 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
969 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
970 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
971 :     while running CMB.make. The point is that the single symbol
972 :     NO_PLUGINS is definde in all three cases.)
973 :    
974 :     I changed the three locations within the sources that get compiled
975 :     during CMB.make where ml-yacc or ml-lex input is processed: When
976 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
977 :     is bypassed.
978 :    
979 :     When bootstrapping new versions of the compiler, there can be
980 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
981 :     are not available or otherwise not operational. In this case one can
982 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
983 :     do so, the following command should be issued at the interactive
984 :     prompt:
985 :    
986 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
987 :    
988 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
989 :     files that normally would be generated by ml-yacc and ml-lex.
990 :     (Copies of these files are in the repository.)

996 :     Description:
997 :    
998 :     2nd merge of base from primop-branch-3 into the trunk.

1000 :     Date.scan and Date.fromString fixed;
1001 :     Overloading resolution fixed and some type printing problems corrected.

1005 : blume 2589 Date: 2007/05/23 09:50:00 CDT
1006 :     Description:
1007 :    
1008 :     Changed the installation mechanism for CM tool plugins. These are
1009 :     just libaries and now get installed like ordinary libaries.
1010 :    
1011 :     There are now a number of new installation targets that give some
1012 :     fine-grain control over what classes and suffixes are known, and what
1013 :     they will map to.
1014 :     See config/targets for details.
1015 :    
1016 :     The code that caused plugin installation as part of running a
1017 :     tool's "build" script has been removed. (The build script is for
1018 :     building, not for installing.)

1022 : blume 2578 Date: 2007/05/22 11:50:00 CDT
1023 :     Description:
1024 :    
1025 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
1026 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
1027 :     CM fail if a shell tool reports a non-success exit status. If
1028 :     the control is set to true, then CM will press on after tool failures
1029 :     in the event that the target files exist (even though they are
1030 :     considered outdated). Turning the control to true can be useful for
1031 :     bootstrapping.

1035 :     Date: 2007/05/19
1036 :     Description:
1037 :    
1038 :     Merge of ml-lpt revisions for 110.64.
1039 :    
1040 :     The name of several ml-lpt-lib modules has changed:
1041 :     Repair => AntlrRepair
1042 :     StreamPos => AntlrStreamPos
1043 :     ErrHandlerFn => AntlrErrHandler
1044 :     EBNF => AntlrEBNF
1045 :    
1046 :     The ml-antlr specification format has changed: declarations such as
1047 :     %tokens and nonterminal definitions can occur *multiple* times in the
1048 :     same specification. The semantics are such that each new declaration
1049 :     extends the previous ones. This does not apply to %start or %name,
1050 :     of course.
1051 :    
1052 :     Importing a grammar via %import now includes *all* declarations in from
1053 :     the imported grammar, except for %name, %entry, and %start. Tokens
1054 :     and nonterminals can be dropped using the new %dropping clause of the
1055 :     %import directive; the separate %drop and %extend have been removed.
1056 :    
1057 :     We now allow optional type annotations on nonterminals, using the %nonterms
1058 :     directive as in ml-yacc.
1059 :    
1060 :     The refcell construct is now implemented using SML's regular reference
1061 :     cells, so the :== and !! notation has been deprecated.
1062 :    
1063 :     The ml-antlr tool now does much more checking of specifications, and
1064 :     its error messages have been greatly improved. Error repair for
1065 :     generated parsers has been completely rewritten, and is now both
1066 :     much faster and more accurate.
1067 :    
1068 :     ml-ulex is now more lenient with escape codes (non-SML-standard
1069 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
1070 :     Also, character classes may now include a "-" character at the beginning
1071 :     as is standard in most other regexp tools.
1072 :    
1073 :     All of these changes are documented in the user guide, which has
1074 :     been updated and improved with this merge.

1080 :     Description:
1081 :    
1082 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
1083 :     Significant changes in FLINT and the front end, mostly having to do
1084 :     with a reorganized system for handling primops. Various bug fixes
1085 :     and improvements in printing signatures.

1090 :     Description:
1091 :    
1092 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
1093 :     The ml-antlr specification format has changed: declarations such as
1094 :     %tokens and nonterminal definitions can occur *multiple* times in the
1095 :     same specification. The semantics are such that each new declaration
1096 :     extends the previous ones. Grammar extension constructs have also
1097 :     changed. We now allow type annotations on nonterminals. Finally,
1098 :     the refcell construct is now implemented using SML's regular reference
1099 :     cells, so the :== and !! notation has been deprecated. All of these
1100 :     changes will appear in the 110.64 user guide for ml-lpt.
1101 :    
1102 :     The ml-antlr tool now does much more checking of specifications, and
1103 :     its error messages have been greatly improved. There has also been
1104 :     some work on the error repair process for generated parsers, but this
1105 :     will be further improved in 110.64.

1110 :     Description:
1111 :    
1112 :     More Basis fixes: The Char.fromString (etc.) functions did not handle
1113 :     the "\uxxxx" escape sequence. There is still an outstanding bug with
1114 :     String.fromString the tail is a format escape. I added a comment to
1115 :     this effect in Basis/Implementation/string.sml.

1194 :     Description:
1195 :    
1196 :     Added preliminary support in MLRISC for Staged Allocation, a technique
1197 :     for specifying calling conventions (see
1198 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
1199 :     Initially, we plan to use this code to generate C calls for the AMD64.
1200 :    
1201 :     The staged allocation code base resides in MLRISC/staged-allocation,
1202 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

1208 :    
1209 :     Bug fix: when SaveCState was called with two values to save, a subsequent

1267 :     Description:
1268 :    
1269 :     Brought ml-lpt manual up-to-date with the code. Many minor
1270 :     improvements to the tools, and a few minor bugfixes. Prepared
1271 :     ml-lpt-lib for integration with new UTF8 structure. Changed
1272 :     the interface for creating streams in ml-ulex (we now support
1273 :     stream creation from several kinds of sources). Overall, the
1274 :     tools are now quite stable, and their interfaces are unlikely to
1275 :     change in a way that would break compatibility. More work,
1276 :     however, is needed in the documentation.

1281 :     Description:
1282 :    
1283 :     Implemented library installer. Moved CM plugin code for
1284 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
1285 :     their respective trees. Implemented CM plugin for ml-ulex
1286 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
1287 :     and ml-antlr.
1288 :    
1289 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
1290 :     CM tools. (It turns out to be too messy to do otherwise because
1291 :     there is too much code that during installation relies on the presence
1292 :     of these tools -- resulting in a tricky ordering problem.)

1299 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
1300 :     Modified CM's startup code to use shiftArgs as it processes
1301 :     command line arguments. This way, the init code in each .sml-file
1302 :     or library that is mentioned at the top level will see only
1303 :     those arguments that have not yet been processed at this point.
1304 :     In other words, the init code can "seize control" and process the
1305 :     remaining command line.

1372 :     Description:
1373 :    
1374 :     Added code to CM's "standard shell tool" implementation which
1375 :     causes it to tolerate (with a warning) the situation where the shell
1376 :     command fails (e.g., due to the shell command's non-existence)
1377 :     as long as all target files exist.
1378 :    
1379 :     This makes it possible to, e.g., build ml-yacc from sources even if
1380 :     svn checkout messed up the time stamps on files in such a way that
1381 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
1382 :     be needed to re-process yacc.grm, but obviously it might not yet be
1383 :     available at that time.)

1390 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
1391 :     recvVecFromNB' in the SOCKET signature. This error is actually
1392 :     in the SML Basis specification too.

1422 :     Tag: release-110.60
1423 :     Description:
1424 :    
1425 :     New working release (110.60). NEW BOOTFILES!
1426 :    
1427 :     This is the first subversion-hosted release. There are also changes
1428 :     to the directory layout. Here is a table:
1429 :    
1430 :     (All pathnames are relative to the SML/NJ "root" directory.)
1431 :    
1432 :     config -> config
1433 :    
1434 :     src/cm -> base/cm
1435 :     src/compiler -> base/compiler
1436 :     src/runtime -> base/runtime
1437 :     src/system -> base/system
1438 :    
1439 :     src/cm/pgraph -> pgraph
1440 :    
1441 :     src/READMES -> base/READMES
1442 :     src/$notefile -> base/NOTES/$notefile
1443 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1444 :     MACOSXINSTALL WININSTALL
1445 :    
1446 :     src/smlnj-lib -> smlnj-lib
1447 :     src/MLRISC -> MLRISC
1448 :     ckit -> ckit
1449 :     src/cml -> cml
1450 :     src/eXene -> eXene
1451 :     src/heap2asm -> heap2asm
1452 :     src/lexgen -> lexgen
1453 :     src/ml-burg -> ml-burg
1454 :     src/ml-lex -> ml-lex
1455 :     src/ml-yacc -> ml-yacc
1456 :     src/ml-nlffi-lib -> nlffi/lib
1457 :     src/ml-nlffigen -> nlffi/gen
1458 :     src/smlnj-c -> smlnj-c
1459 :     src/tools/TraceDebugProf -> trace-debug-profile
1460 :    
1461 :     In addition, there is also a new
1462 :    
1463 :     ml-lpt
1464 :    
1465 :     directory containing two new program generator tools: ml-ulex and
1466 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1467 :     LL(k) parser generator). These tools are currently "beta-quality"
1468 :    
1469 :     The latest versios of the sources can now be obtained anonymously
1470 :     via subversion. For this, it is useful to first check out
1471 :    
1472 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1473 :    
1474 :     and put the resulting directory on your shell's PATH. This provides
1475 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
1476 :     and refresh-all.sh.
1477 :    
1478 :     To create a freshly checked-out copy of the sources, do
1479 :    
1480 :     checkout-all.sh [dir]
1481 :    
1482 :     where dir is the optional SML/NJ root directory (default is ".").
1483 :    
1484 :     This creates the above directory layout. Each subdirectory of
1485 :     the root is under individual subversion control. The stat-all.sh
1486 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
1487 :     each of these subtrees.

1490 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
1491 : blume 2155 Date: 2006/11/02 12:20:00 CST
1492 :     Description:
1493 :    
1494 :     Reorganized directory layout.
1495 :    
1496 :     This is a temporary solution, more reorganization is to come.
1497 :    
1498 :     The basic idea is to have a number of toplevel trees, each corresponding
1499 :     to a well-defined part of the overall system. Each part can be
1500 :     maintained individually, even in separate source repositories,
1501 :     although currently we still serve everything out of the main
1502 :     smlnj-gforge tree.
1503 :    
1504 :     Installer and and scripts have been updated to reflect the new
1505 :     layout. The installer (base/src/system/smlnj/installer) is now
1506 :     "scriptable" to avoid burning too much knowledge about the
1507 :     layout into SML source code. The main script used by the installer
1508 :     is in config/actions.
1509 :    
1510 :     The main change is that many of the subdirectories of what used to
1511 :     be known as "src" have moved to the toplevel. The "src" directory
1512 :     itself has moved down into a subtree called "base". (We may eventually
1513 :     get rid of the extra level of indirection represented by "src".)
1514 :    
1515 :     The layout is now as follows:
1516 :    
1517 :     toplevel tree name | default repository
1518 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1519 :     -------------------+----------------------------------------------------
1520 :     config | $gf/config/trunk
1521 :     |
1522 :     base | $gf/sml/trunk
1523 :     |
1524 :     smlnj-lib | $gf/smlnj-lib/trunk
1525 :     MLRISC | $gf/MLRISC/trunk
1526 :     |
1527 :     ml-yacc | $gf/ml-yacc/trunk
1528 :     ml-lex | $gf/ml-lex/trunk
1529 :     ml-burg | $gf/ml-burg/trunk
1530 :     lexgen | $gf/lexgen/trunk
1531 :     heap2asm | $gf/heap2asm/trunk
1532 :     |
1533 :     cml | $gf/cml/trunk
1534 :     eXene | $gf/eXene/trunk
1535 :     ckit | $gf/ckit/trunk
1536 :     nlffi | $gf/nlffi/trunk
1537 :     |
1538 :     smlnj-c | $gf/smlnj-c/trunk
1539 :    
1540 :     In $gf/admin there are a few useful shell scripts for checking out
1541 :     and maintaining the entire collection of trees:
1542 :    
1543 :     admin/checkout-all.sh [dir]
1544 :     -- optionally creates dir and checks out all trees from their
1545 :     default repositories; if dir is missing, checkout into .
1546 :     admin/refresh-all.sh [dir]
1547 :     -- looks at all trees (from the above list) in dir (default: .)
1548 :     and runs "svn update" if the tree exists and is under
1549 :     subversion control;
1550 :     non-existing or non-subversion trees are skipped
1551 :     admin/stat-all.sh [dir]
1552 :     -- like refresh-all.sh, but runs "svn stat" instead

1732 :     Description:
1733 :    
1734 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1735 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1736 : blume 2155 at the time when config/preloads is processed, the library has to
1737 : mblume 1878 be referred to by another name. In 110.57 this would be
1738 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1739 :     to be valid as well.)
1740 :    
1741 :     Thanks to Todd Wilson (Fresno) for alerting me to this issue.

1794 :     Tag: blume-22051115-versiontool
1795 :     Description:
1796 :    
1797 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1798 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1799 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1800 :     it. Instead, it has the status of "user code", so it should use
1801 :     $/basis.cm to refer to the Basis library. (At least that's true for
1802 :     the purpose of bootstrapping the previous change. In the future it
1803 :     might make sense to have versiontool.cm refer to
1804 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1805 :     compiler itself uses.)
1806 :    
1807 :     Also patched src/system/testml to have it activate those extra anchor
1808 :     bindings in config/extrapathconfig.

1813 :     Tag: blume-22051115-libraries
1814 :     Description:
1815 :    
1816 :     This change affects the way the following libraries are tied into
1817 :     the system:
1818 :    
1819 :     $/basis.cm
1820 :     $/smlnj-lib.cm
1821 :     $/pp-lib.cm
1822 :     $/controls-lib.cm
1823 :     $/html-lib.cm
1824 :     $/ml-yacc-lib.cm
1825 :    
1826 :     These libraries are now internally (as seen from the source code
1827 :     of the implementation itself) known by the following names:
1828 :    
1829 :     $smlnj/basis/basis.cm
1830 :     $smlnj/smlnj-lib/smlnj-lib.cm
1831 :     $smlnj/smlnj-lib/pp-lib.cm
1832 :     $smlnj/smlnj-lib/controls-lib.cm
1833 :     $smlnj/smlnj-lib/html-lib.cm
1834 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1835 :    
1836 :     This makes it possible to work with code that requires different
1837 :     versions of these libraries, and which refers to these libraries using
1838 :     their "default" names (i.e., the first set of names above). In other
1839 :     words, one can un-define or re-define those default names without
1840 :     compromising the proper functioning of the compiler itself.
1841 :    
1842 :     A similar procedure had already been performed for several of the
1843 :     MLRISC libraries that are linked into the compiler. I did some
1844 :     cleanup on this code.
1845 :    
1846 :     A new file in the config directory (named extrapathconfig) is
1847 :     responsible for setting up path anchors that the compiler itself does
1848 :     not need, but that are typically required by user code.

2028 :     Description:
2029 :    
2030 :     Added mechanism for re-creating a heap file for the interactive system
2031 :     after configuration variables have been changed.
2032 :    
2033 :     CM.redump_heap : string -> unit
2034 :    
2035 :     This is much like SMLofNJ.exportML, but starting from the resulting
2036 : blume 2155 heap does not return to the caller of CM.redump_heap but
2037 : mblume 1792 restarts the interactive system from scratch. The original call of
2038 :     CM.redump_heap does not return but ends the interactive session.
2039 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
2040 :    
2041 :     Internally, redump_heap winds the dynamic execution context back to
2042 :     the point where the original heap image was created and re-executes
2043 :     the heap image generation code in the boot code.

2159 :     Tag: blume-20050114-heap2exec
2160 :     Description:
2161 :    
2162 :     Implemented new (but still experimental) heap2exec facility. This is
2163 :     tested under Mac OS X and should work under Linux (will test shortly).
2164 :     It will probably also work on the Sparc (will test some time later).
2165 :    
2166 :     - removed old "HACKED_STANDALONE" hack from runtime
2167 :    
2168 :     To be able to test this, uncomment the request for "heap2asm" in
2169 :     config/targets prior to installation. (Notice that this is different
2170 :     from "heap2exec" mentioned below. Not a typo.)
2171 :    
2172 :     To perform an actual test, run the command
2173 :    
2174 :     $ bin/heap2exec heapfile execfile
2175 :    
2176 :     (You can put heap2exec on your shell's path.)
2177 :    
2178 :     For example, run
2179 :    
2180 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
2181 :    
2182 :     This will create a standalone executable called "mly" which you can
2183 :     then invoke directly as a command.

2208 :     (The parameter-passing part of the picture has not complete. But
2209 :     data structure access seems to work.)
2210 :    
2211 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
2212 :     (On the Mac, it is big-endian. And that's currently our only
2213 :     PPC platform.)

2328 :     Tag: blume-20041124-position
2329 :     Description:
2330 :    
2331 :     The compiler can now be compiled in a mode that makes structure Position
2332 :     equal to Int64. The default, however, is unchanged (Position = Int31)
2333 :     for the time being.
2334 :    
2335 :     To enable 64-bit positions, use the following procedure:
2336 :    
2337 :     1. Start sml
2338 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
2339 :     3. Type
2340 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
2341 :     4. Run CMB.make() as usual.
2342 :    
2343 :     This is barely tested. The only test so far was a little SML program
2344 :     counting the number of characters in an 8-gigabyte file by
2345 :     reading it character-by-character. That test was successful.
2346 :    
2347 :     In support of 64-bit positions, a number of new functions have been
2348 :     added to the runtime system.

2392 :     The date string is generated at bootstrap time (during makeml).
2393 :    
2394 :     - In a previous commit, fixed a minor issue with how polyequal is being
2395 :     translated. In particular, the code now "looks through" abstractions.
2396 :     This results in slightly fewer polyEqual warnings and hopefully slightly
2397 :     more efficient code. Important examples for where this matters are
2398 :     the new int64 and word64 types.

2416 :     conversions from and to LargeWord. (Eventually these need to be identities,
2417 :     but for the time being they don't even make sense because LargeWord is
2418 :     32-bit wide.)
2419 :    
2420 :     Also started to add similar support for Int64, but major pieces of that
2421 :     are still missing.

2427 :     Description:
2428 :    
2429 :     Structure Word64 is now (almost) complete, word literals and patterns
2430 :     seem to work. There are a few odd pieces missing. In particular,
2431 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2432 :     at the moment.
2433 :    
2434 :     Making Word64 official would mean that LargeWord becomes Word64. But
2435 :     this requires extreme care because most word-word conversions have to
2436 :     go through LargeWord, so making a mistake means loss of efficiency or
2437 :     worse. Eventually there will be a solution similar to (but actually
2438 :     simpler than) what I did with IntInf.

2473 :     - Made corresponding changes to config/install.sh and config/unpack.
2474 :     - Default contents of config/srcarchiveurl uses $VERSION and
2475 :     normally does not have to be edited to reflect a version change.
2476 :    
2477 :     (As a result, a version change can be done by just editing
2478 :     config/version, the rest is now automatic.)

2501 :     (the callee already pops the implicit argument which points to

2518 :     Tag: blume-20041020-standalone-backtrace
2519 :     Description:
2520 :    
2521 :     Added a mechanism for getting back-trace information from standalone
2522 :     programs. Here is how it works:
2523 :    
2524 :     1. The part of the program from which you want to get backtrace
2525 :     information (usually the whole program) should be wrapped with
2526 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
2527 :     main program could be modified from something like
2528 :    
2529 :     fun main (pgm, args) = ...
2530 :    
2531 :     to
2532 :    
2533 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2534 :    
2535 :     2. To be able to access BackTrace.monitor, you have to add
2536 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
2537 :     main function.
2538 :    
2539 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2540 :     CM might have created in the past for your project).
2541 :    
2542 :     4. Build the system using this command line:
2543 :    
2544 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2545 :     myprog.cm MyProg.main myprog
2546 :    
2547 :     instead of the usual
2548 :    
2549 :     ml-build myprog.cm MyProg.main myprog
2550 :    
2551 :     I changed a library name:
2552 :    
2553 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2554 :    
2555 :     New libraries:
2556 :    
2557 :     $smlnj-tdp/back-trace.cm
2558 :     -- when loaded causes the back-trace plugin to be installed
2559 :     $smlnj-tdp/coverage.cm
2560 :     -- when loaded causes the coverage plugin to be installed

2576 :     Description:
2577 :    
2578 :     * Test coverage tool added!
2579 :     * Further reorganization of tracing-, debugging-, and profiling support:
2580 :    
2581 :     - moved original BTImp -- now called BackTrace -- into a separate
2582 :     library called $/trace-debug-profile.cm
2583 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2584 :     - only the instrumentation mechanism is now left in the compiler proper
2585 :     - BackTrace module is a plugin which is NOT plugged in by default
2586 :     - Coverage module is another such plugin
2587 :    
2588 :     To get the benefits of any of these plugin modules, the code in
2589 :     question must be compiled with tdp instrumentation turned on. This
2590 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2591 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2592 :    
2593 :     Plugins are selected at link time. (Pre-compiled instrumented code
2594 :     can be re-loaded with different plugins in effect.) When an
2595 :     instrumented module is linked, whatever plugins are at that time
2596 :     enabled will come into effect for that module.
2597 :    
2598 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2599 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2600 :     To enable the coverage plugin, load the same library and invoke
2601 :     Coverage.install().
2602 :    
2603 :     Back-traces are generated automatically on uncaught exceptions and
2604 :     when the code in question explicitly invokes BackTrace.trigger().
2605 :    
2606 :     Coverage (and execution frequency-) information must be queried
2607 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2628 :    
2629 :     This is is preparation of using the original back-trace
2630 :     instrumentation for other purposes. "TDP" stands for
2631 :     Trace/Debug/Profile.
2632 :    
2633 :     The control flag controlling whether instrumentation is on or off is now
2634 :     registered under a different name, so instead of running sml as
2635 :    
2636 :     sml -Cinstrument.btrace-mode=true

2656 :     Description:
2657 :    
2658 :     Fixed handling of keywords in .cm files: After seeing "is" the lexer
2659 :     treats subsequent occurrences of "group", "library", "source", "is",
2660 :     "*", and "-" as ordinary identifiers rather than keywords.
2661 :    
2662 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool
2663 :     is supposed to accept a tool argument called "source", but this did
2664 :     not work because of the clash with the keyword.

2708 :    
2709 :     * Moved the "version" magic into its own little library under

2712 : mblume 1639
2713 : mblume 1672 * At the same time, structure CompilerVersion is now known as
2714 :     structure SMLNJVersion.
2715 : mblume 1639
2716 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2717 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2718 :     Also, loading the versiontool does not work when rebuilding the system
2719 :     because CM is not properly initialized at that time.

2724 :     Tag: blume-20040929-autoversion
2725 :     Description:
2726 :    
2727 :     Implemented some CM magic to have
2728 :     file src/compiler/TopLevel/main/version.sml
2729 :     generated automagically.
2730 :     The version is taken from two files: config/version and config/release.
2731 :     The first is expected to contain a two-part version number such as 110.49.
2732 :     The second should contain a single number, but it may be missing.
2733 :    
2734 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2735 :     time the version tool is loaded (which is the first time you say CMB.make),
2736 :     then the tool will increment the value stored in config/release every
2737 :     time CMB.make is invoked.
2738 :    
2739 :     The binfile format is now insensitive to anything beyond the first
2740 :     two components of a version number, so bumping the release does not render
2741 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2742 :     during development without invalidating existing binfiles.
2743 :    
2744 :     In any case, every CMB.make updates the date information in version.sml.
2745 :     (This is the date that is printed in the banner.)

2758 :     Tag: blume-20040927-controls
2759 :     Description:
2760 :    
2761 :     Added two pieces of functionality to the Controls interface:
2762 :    
2763 :     1. val save'restore: 'a control -> unit -> unit
2764 :    
2765 :     grabs the current value of the control in stage 1 and restores it
2766 :     in stage 2.
2767 :    
2768 :     2. val set' : 'a control * 'a -> unit -> unit
2769 :    
2770 :     stores the given value into the control in stage 2 (i.e., delayed)
2771 :     but does all error checking in stage 1.
2772 :     (This is for string controls that need to do parse their argument --
2773 :     something that might fail. In some cases, notably in CM, one
2774 :     already knows the intended argument but wants to delay the actual
2775 :     assignment until a time when error recovery would be more difficult.)
2776 :    
2777 :     Changed the handling of controls in tool arguments to classes "sml" and
2778 :     "lazysml":
2779 :     - use Controls.save'restore as a more robust way of restoring the
2780 :     old value (in particular: without having to re-parse the string)
2781 :     - use controls to handle the "overload" keyword in the init group
2782 :     (I believe this change actually fixes a long-standing obscure bug.)

2787 :     Tag: blume-20040927-lazysml
2788 :     Description:
2789 :    
2790 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2791 :     difference to "sml" is that compilation is done with Control.lazysml
2792 :     set to true. A source of class "lazysml" is automatically recognized
2793 :     by a file name suffix of ".lml".
2794 :    
2795 :     In addition to the above feature, the original class "sml" now also
2796 :     supports a tool argument "lazy" which has the same effect. As a
2797 :     result, the following three lines are equivalent:
2798 :    
2799 :     foo.sml : lazysml
2800 :     foo.sml : sml (lazy)
2801 :     foo.sml (lazy)
2802 :    
2803 :     The setting goes into effect both during parsing and during
2804 :     compilation. The original setting is restored right after parsing and
2805 :     after compilation, respectively.
2806 :    
2807 :     In addition to all the above, there is also a general mechanism to set
2808 :     ANY of the "controls" that are available at the command line via
2809 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2810 :     apply as well. (In fact, "lazy" is implemented as a special case of
2811 :     the general mechanism.)
2812 :    
2813 :     The .cm file syntax uses a new keyword tool argument called "with".
2814 :     There are several ways of indicating the desired settings:
2815 :    
2816 :     foo.sml (with:parser.quotations=true)
2817 :     foo.sml (with:(name:parser.quotations value:true))
2818 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2819 :     foo.sml (with:(name1=value1 name2=value2 ...))
2820 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2821 :    
2822 :     etc.
2823 :    
2824 :     Another possible abbreviation is to leave out the =v or value:v part
2825 :     if the name refers to a boolean control (in which case the value is
2826 :     taken to be true). Thus, one could get lazy sml also by saying:
2827 :    
2828 :     foo.sml (with:parser.lazy-keyword=true)
2829 :     foo.sml (with:parser.lazy-keyword)
2830 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2831 :     foo.sml (with:(name:parser.lazy-keyword))

3183 :     Description:
3184 :    
3185 :     Changed the interface of structures Timer and Unix to match the most
3186 :     recent Basis spec.
3187 :    
3188 :     In the case of Unix there still seems to be an open/weird issue:
3189 :    
3190 :     The {text,bin}{In,Out}streamOf functions are supposed to create
3191 :     fresh streams whenever they are called -- as opposed to have them
3192 :     return the same stream every time. This design is supposed to
3193 :     prevent space leaks caused by proc values hanging on to streams.
3194 :    
3195 :     The reap function, on the other hand, is supposed to close the
3196 :     streams. This cannot be done without having a handle on the
3197 :     stream in proc after all...
3198 :    
3199 :     I took the liberty to implement the following stopgap solution:
3200 :    
3201 :     The proc value hangs on to the most recently created stream(s).
3202 :     Reap closes those. If either or both of the two streams hadn't
3203 :     been created at all yet, then reap will close the corresponding
3204 :     file descriptors directly.
3205 :    
3206 :     PS: I don't understand the original space leak argument anymore. If
3207 :     a proc hangs on to the imperative stream, then I/O operations on those
3208 :     will advance the state of the cached stream and avoid the space leak.

3221 :     Tag: blume-20040525-group-owner
3222 :     Description:
3223 :    
3224 :     CM now ignores (but still accepts) the "owner" information in group
3225 :     descriptions. The owner of a group is its next enclosing
3226 :     library. Each group must have a unique owner. (There is a virtual
3227 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
3228 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
3229 :     and CM would check that such a declaration is correct. The new scheme
3230 :     is to have CM check that for each group there is precisely one owning
3231 :     library.
3232 :    
3233 :     The advantage of the new scheme is that the programmer no longer needs
3234 :     to maintain the somewhat annoying owner information. The downside is
3235 :     that CM cannot enforce the ownership rule across multiple runs of
3236 :     CM.make. Fortunately, enclosing the same group in two different
3237 :     libraries A and B which are not part of the same program does not
3238 :     cause real problems.

3262 :     gets rid of those at the end, so they don't accumulate under .cm.
3263 :

3291 :     Hi,
3292 :    
3293 :     Attached to this email you find a diff against sml/nj 110.45
3294 :     that will enable socket support under Windows.
3295 :    
3296 :     To apply the patch (using unix or cygwin)
3297 :     1) gunzip runtime.diff.gz
3298 :     2) "cd" into "src/runtime" in the source tree of a fresh
3299 :     110.45 installation.
3300 :     3) patch -p 1 < [your/path/to]runtime.diff
3301 :    
3302 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
3303 :     I only ran a few tests for basic socket client functionality
3304 :     (which worked fine). Especially the functions that use ioctl
3305 : mblume 1490 are not tested at all and might not work (see below).
3306 :    
3307 :     I implemented this since we want to move to a newer version of sml/nj
3308 :     but need socket support in order to use it. This is the first time I
3309 :     even had a look at the sml/nj source, so please review my changes
3310 :     before making this part of the distribution! Here are a few issues
3311 : blume 2155 that I think might be better for someone to solve who is more
3312 : mblume 1490 familiar with the sml/nj source (and socket programming):
3313 :    
3314 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
3315 :     exception since I could not figure out what the windows equivalent
3316 :     of these functions is
3317 :    
3318 :     - In sockets-osdep.h there are a some #include statements that are
3319 :     only used in a few files that include sockets-osdep.h
3320 :    
3321 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
3322 :     does not process its return value since I don't know how to
3323 :     report an error upwards.
3324 :    
3325 :     - It would probably be good to have a call to WSACleanup() when
3326 : blume 2155 the library is unloaded (if there is such a possibility).
3327 : mblume 1490 Otherwise I think Windows will take care of this automatically
3328 :     when the process finishes.
3329 :    
3330 :     - I used ioctlsocket() as a replacement for ioctl() but I have
3331 :     no idea if that is actually the proper replacement on Windows.
3332 :    
3333 :     - All these issues are marked in the code by "FIXME" comments.
3334 :    
3335 : blume 2155 We use sml/nj extensively in our products and are quite happy
3336 :     with it. I hope this contribution will help you.
3337 : mblume 1490
3338 :     Keep up the good work!

3422 :    
3423 : blume 2155 does not work on Windows unless we explicitly export symbols
3424 :     such as 'malloc' during linking. We fixed this by explicitly
3425 : allenleung 1468 exporting the required symbols with the magic gcc incantation:
3426 :    
3427 :     -Wl,--export-all cygwin.def
3428 :

3431 : allenleung 1468
3432 : blume 2155 I suspect this is a Windows problem and we'll have to

3434 : allenleung 1468 we build the native win32 version with the system
3435 : blume 2155 calls LoadLibrary/GetProcAddress.

3560 :     Tag: blume-20030926-ppautoload
3561 :     Description:
3562 :    
3563 :     I modified the read-eval-print loop so that the autoloader gets
3564 :     invoked whenever the prettyprinter tries to look up a symbol that
3565 :     is not currently defined in the toplevel environment but which
3566 :     appears in CM's autoload registry. As a result, we see far fewer of
3567 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3568 :    
3569 :     In addition to this I tried to clean up some pieces of the Basis
3570 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3571 :     instances of these ?.Foo.Bar.xxx names from being printed.
3572 :    
3573 :     The mechanism that picks names for types still needs some work, though.
3574 :     (Right now it seems that if there is a type A.t which is defined to
3575 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3576 :     "?.B.u" although the perhaps more sensible solution would be to use
3577 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3578 :     a chain of DEFtycs not farther than there are corresponding toplevel
3579 :     names in the current environment.)

3585 :     Description:
3586 :    
3587 :     Another installer tweak: All the ML code for the installer is now
3588 :     compiled during CMB.make and put into a little library called
3589 :     $smlnj/installer.cm. The installation then simply invokes
3590 :    
3591 :     sml -m $smlnj/installer.cm
3592 :    
3593 :     and everything happens automagically.
3594 :    
3595 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3596 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3597 :     and BINDIR.
3598 :    
3599 :     The new scheme guarantees that the ML code responsible for the installation
3600 :     is in sync with the APIs of the main system. Also, the installer is
3601 :     somewhat faster because the installer script is precompiled.

3618 :     Tag: blume-20030924-sockets
3619 :     Description:
3620 :    
3621 :     1. Fixed SOCKET API and implementation to match Basis spec.
3622 :     This required changing the internal representation of sockets to one
3623 :     that remembers (for each socket file descriptor) whether it is currently
3624 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3625 :     call is made only if the state actually needs to change).
3626 :    
3627 :     2. OS-specific details of sockets were moved into separate files, thus
3628 :     making it possible to unify the bulk of the socket implementations
3629 :     between Unix and Win32.
3630 :    
3631 :     3. CML's socket API changed accordingly.
3632 :     (Note that we need to remove non-blocking functions from this API
3633 :     since they are redundant in the case of CML!)
3634 :    
3635 :     4. CML's socket implementation now makes use of non-blocking functions
3636 :     provided by Basis, thus removing all OS-dependent code from this part
3637 :     of CML.
3638 :    
3639 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3703 :     with code that generates these values from their corresponding
3704 :     integer counterparts.
3705 :    
3706 :     Made all(?) the slice-related changes to the Basis and made everything
3707 :     compile again...

3751 :     Tag: blume-20030909-installer
3752 :     Description:
3753 :    
3754 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3755 :     Modified config/install.bat to take advantage of it. Also modified
3756 :     config/install.sh (and called it config/new-install.sh) to take advantage
3757 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3758 :     independent.)
3759 :    
3760 :     The installer can now install everything under Win32
3761 :     as well as under *nix as long as it compiles.
3762 :    
3763 :     Other changes:
3764 :    
3765 :     - made CML compile again under Win32
3766 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3767 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3768 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3769 :     same as type int; under Win32 it isn't
3770 :     - fixed some slice-related problems in the win32-specific parts of CML
3771 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3772 :     (under Win32, the volume name is case-insensitive, and the
3773 :     OS.Path code compares volume names for equality)

3783 :     CM depends on it. (CM otherwise goes into an infinite loop in certain

3789 : mblume 1352 Tag: blume-20030905-slices-etc
3790 : mblume 1350 Description:
3791 :    
3792 :     1. Changed interface to vectors and arrays in Basis to match
3793 :     (draft) Basis spec.
3794 :     2. Added signatures and implementations of slices according to
3795 :     Basis spec.
3796 :     3. Edited source code throughout the system to make it compile again
3797 :     under 1. and 2. (In some cases code had to be added to have it
3798 :     match the new signatures.)
3799 :     4. MLRISC should be backward-compatible: the copies of the originals
3800 :     of files that needed to change under 3. were retained, the .cm files
3801 :     check the compiler version number and use old versions when
3802 :     appropriate.
3803 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3804 :     dirstream -> string option (in accordance with Basis spec).
3805 :     6. When generating code that counts lines, ml-lex used function
3806 :     CharVector.foldli, taking advantage of its old interface.
3807 :     This has been replaced with the corresponding code from
3808 :     CharVectorSlice. (html-lex must be re-lexed!)
3809 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3810 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3811 :     8. Removed temporary additions (fromInternal, toInternal) from the
3812 :     (now obsolete) IntInf in smlnj-lib/Util.
3813 :     9. Cleaned up structure Byte.
3814 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3815 :     Cleaned/corrected implementation of Date.
3816 :     (Still need to check for correctness; implement better canonicalizeDate.)
3817 :     11. Added "scan" to signature IEEE_REAL.
3818 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3819 :     mod and rem when second operand is 2 (for parity checks).]
3820 :     13. Changed representation of type Time.time, using a single IntInf.int
3821 :     value counting microseconds. This considerably simplified the
3822 :     implementation of structure Time. We now support negative time
3823 :     values; scan and fromString handle signs.
3824 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3825 :     ArraySlice).

3830 :     Tag: blume-20030828-intinf
3831 :     Description:
3832 :    
3833 :     This is a major update which comes with a version number bump
3834 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3835 :     and an implementation of IntInf in the Basis.
3836 :    
3837 :     There are a fairly large number of related changes and updates throughout
3838 :     the system:
3839 :    
3840 :     Basis:
3841 :     - Implemented IntInf.
3842 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3843 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3844 : mblume 1347 - Added FixedInt as a synonym for Int32.
3845 :    
3846 :     compiler:
3847 :     * Added support for a built-in intinf type.
3848 :     - literals
3849 :     - pattern matching
3850 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3851 :     - overloading on literals and operations
3852 :    
3853 :     This required adding a primitive type intinf, some additional
3854 :     primops, and implementations for several non-trivial intinf
3855 :     operations in Core. (The intinf type is completely abstract
3856 :     to the compiler; all operations get delegated back to the Core.)
3857 :    
3858 :     * Intinf equality is handled by polyequal. However, the compiler
3859 :     does not print its usual warning in this case (since polyequal
3860 :     is the right thing to do there).
3861 :    
3862 :     * Improved the organization of structure InlineT.
3863 :    
3864 :     * A word about conversion primops:
3865 :     If conversions involving intinf do not cancel out during
3866 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3867 : mblume 1347 Since all core access must be resolved already during the FLINT
3868 :     translate phase, it would be too late a the time of CPS contract
3869 : mblume 1348 to add new Core calls. For this reason, conversion primops
3870 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3871 :     they are supposed to convert, and 2. the Core function that
3872 :     can help with this conversion if necessary. If CPS contract
3873 : mblume 1348 eliminates a primop, then the associated Core function becomes
3874 :     dead and goes away. Intinf conversion primops that do not get
3875 :     eliminated by CPS contract get rewritten into calls of their
3876 :     core functions by a separate, new phase.
3877 : mblume 1347
3878 :     interactive system:
3879 :     - Control.Print.intinfDepth controls max length of intinf constants
3880 :     being printed. (Analogous to Control.Print.stringDepth.)
3881 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3882 :     duplicates; replaced some of the code with code that makes better
3883 :     use of library functionality.
3884 :    
3885 :     CM:
3886 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3887 :     are no longer silent.
3888 :    
3889 :     CKIT:
3890 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3891 :     in favor of LargeInt -- which is now the same as IntInf.
3892 :     CKIT-knowledgable people should check whether this is what's
3893 :     intended and otherwise change things back to using Int32 or
3894 :     FixedInt.
3895 :    
3896 :     Throughout the code:
3897 : mblume 1348 Started using IntInf.int literals and built-in operations
3898 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3917 :     Tag: blume-20030811-windows
3918 :     Description:
3919 :    
3920 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3921 :    
3922 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3923 :    
3924 :     This patch restores SML/NJ's ability to run under win32. There are a
3925 :     number of changes, including fixes for several bugs that had gone
3926 :     unnoticed until now:
3927 :    
3928 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3929 :     trying to run the win32 version from within cygwin.)
3930 :    
3931 :     - There are a number of simple .bat scripts that substitute for their
3932 :     corresponding Unix shell-scripts. (See below.)
3933 :    
3934 :     - The internals of ml-build have been modified slightly. The main
3935 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3936 :     using OS.Process.system, the ML process delegates this task back
3937 :     to the script. Otherwise problems arise in mixed environments such
3938 :     as Cygwin where scripts look and work like Unix scripts, but
3939 :     where OS.Process.system cannot run them.
3940 :    
3941 :     - In CM, the srcpath pickler used native pathname syntax -- which
3942 :     is incorrect in the case of cross-compilation. The new pickle format
3943 :     is independent of platform-specific naming conventions.
3944 :    
3945 :     - Path configuration files (such as lib/pathconfig) can now choose
3946 :     between native and standard syntax. Placing a line of the form
3947 :    
3948 :     standard!
3949 :    
3950 :     into the file causes all subsequent paths to be interpreted using
3951 :     CM standard pathname syntax (= Unix conventions); a line
3952 :    
3953 :     native!
3954 :    
3955 :     switches back to native style. This was needed so that
3956 :     path config files can be written portably, see src/system/pathconfig.
3957 :    
3958 :     - Runtime system:
3959 :    
3960 :     - win32-filesys.c: get_file_time and set_file_time now
3961 :     access modification time, not creation time.
3962 :    
3963 :     - I/O code made aware of new array representation.
3964 :    
3965 :     - Bug fixes in X86.prim.masm.
3966 :    
3967 :     - src/system/makeml made aware of win32. (For use under cygwin
3968 :     and other Unix-environments for windows.)
3969 :    
3970 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3971 :     which caused BinIO.inputAll to fail consistently.
3972 :    
3973 :     .bat scripts:
3974 :    
3975 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3976 :    
3977 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3978 :     applications (sml, ml-yacc, ml-lex).
3979 :     - ml-build.bat: analogous to ml-build.
3980 :     - config\install.bat: Analogous to config/install.sh. This requires
3981 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3982 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3983 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3984 :     and the bootfile hierarchy must have been unpacked under
3985 :     sml.boot.x86-win32.
3986 :     The script is very primitive and does a poor job at error checking.
3987 :     It only installs the base system, ml-lex, and ml-yacc. No other
3988 :     libraries are being installed (i.e., you get only those that
3989 :     are part of the compiler.)
3990 :     - link-sml.bat: analogous to .link-sml, but not currently used
3991 :    
3992 :     Unrelated bug fixes:
3993 :    
3994 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3995 :     types.
3996 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3997 :     otherwise.)

4022 :    
4023 :     Two changes:

4026 :     be treated as errors (default is false).
4027 :     2. Cleaned up the *entire* source tree so that CMB.make goes through

4034 :     Description:
4035 :    
4036 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
4037 :    
4038 :     This mainly affects the quality of error messages. However, some
4039 :     of the code is now more straightforward than before. (Treatment of
4040 :     the above four constructs in translate.sml is much simpler than
4041 :     the "macro-expansion" that was going on before. Plus, the mach-
4042 :     compiler no longer gets invoked just to be able to compile an
4043 :     if-expression.)
4044 :    
4045 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
4046 :     interactive loop.

4092 :     Description:
4093 :    
4094 :     Fixed a serious bug in the rewrite code for FP spilling/reloading that

4096 :     spilled. (Because of this bug, e.g., nucleic stopped compiling between
4097 :     110.37 and 110.38.)
4098 :     There was another set of potential problems related to the handling of
4099 :     MLRISC annotations (but those did not yet cause real problems, apparently).

4105 :     Description:
4106 :    
4107 :     Added a call of SrcPath.sync at the beginning of Parse.parse (in CM).
4108 :     This fixes the problem of CM getting confused by files that suddenly
4109 :     change their identity (e.g., by getting unlinked and recreated by some
4110 :     text editor such as vi). There might be a better/cheaper/cleaner way
4111 :     of doing this, but for now this will have to do.

4125 :     Description:
4126 :    
4127 : blume 1282 In good old tradition, there has been a slight hiccup so that we have
4128 :     to patch 110.42 after the fact. The old release tag has been replaced
4129 :     (see below).
4130 :    
4131 :     The change solves a problem with two competing approaches the
4132 :     configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
4133 :     each other's way.
4134 :    
4135 :     This change only affects the runtime system code and the installer script.
4136 :     (No new bootfiles.)

4150 :     Description:
4151 :    
4152 :     The mltree operator DIVS must be implemented with an overflow check on
4153 :     the PPC because the hardware indicates divide-by-zero using "overflow" as
4154 :     well.

4159 :     Tag: blume-20020723-smlnj-home
4160 :     Description:
4161 :    
4162 :     Sml now senses the SMLNJ_HOME environment variable. If this is set,
4163 :     then the bin dir is assumed to be in $SMLNJ_HOME/bin and (unless
4164 :     CM_PATHCONFIG is also set), the path configuration file is assumed
4165 :     to be in $SMLNJ_HOME/lib/pathconfig. This way one can easily move
4166 :     the entire tree to some other place and everything will "just work".
4167 :    
4168 :     (Companion commands such as ml-build and ml-makedepend also sense this
4169 :     variable.)
