819 :     Additional bug fixes included:
820 :    
821 :     * Timer.cpu_timer, etc. type printing corrected (by making

828 :     Date: 2007/05/31 11:40:00 CDT
829 :     Description:
830 :    
831 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
832 :    
833 :     Also, changed the handling of "no core access": When translate.sml
834 :     needs access to a core exception at a time when the core has not
835 :     been set up yet (this only happens when compiling system/smlnj/init/*),
836 :     then don't bother generating the corresponding tests.
837 :    
838 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
839 :     the exception. Unfortunately, that confuses the plambda type checker.
840 :     Moreover, it does not do any good, because at runtime we don't expect
841 :     such an exception to be ever raised. (The code in system/smlnj/init/*
842 :     has to be written very carefully with this in mind!)

854 :     Description:
855 :    
856 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
857 :     with an explicit test for zero division. This should fixes several
858 :     regressions and makes it possible for downstream optimization phases
859 :     to treat these operations as "pure" when they are applied to unsigned
860 :     operands.

884 :    
885 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
886 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
887 :    
888 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
889 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
890 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
891 :     while running CMB.make. The point is that the single symbol
892 :     NO_PLUGINS is definde in all three cases.)
893 :    
894 :     I changed the three locations within the sources that get compiled
895 :     during CMB.make where ml-yacc or ml-lex input is processed: When
896 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
897 :     is bypassed.
898 :    
899 :     When bootstrapping new versions of the compiler, there can be
900 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
901 :     are not available or otherwise not operational. In this case one can
902 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
903 :     do so, the following command should be issued at the interactive
904 :     prompt:
905 :    
906 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
907 :    
908 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
909 :     files that normally would be generated by ml-yacc and ml-lex.
910 :     (Copies of these files are in the repository.)

917 :    
918 :     2nd merge of base from primop-branch-3 into the trunk.
919 :     Additional bug fixes included:
920 :     Date.scan and Date.fromString fixed;

926 :     Description:
927 :    
928 :     Changed the installation mechanism for CM tool plugins. These are
929 :     just libaries and now get installed like ordinary libaries.
930 :    
931 :     There are now a number of new installation targets that give some
932 :     fine-grain control over what classes and suffixes are known, and what
933 :     they will map to.
934 :     See config/targets for details.
935 :    
936 :     The code that caused plugin installation as part of running a
937 :     tool's "build" script has been removed. (The build script is for
938 :     building, not for installing.)

943 :     Description:
944 :    
945 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
946 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
947 :     CM fail if a shell tool reports a non-success exit status. If
948 :     the control is set to true, then CM will press on after tool failures
949 :     in the event that the target files exist (even though they are
950 :     considered outdated). Turning the control to true can be useful for
951 :     bootstrapping.

956 :     Description:
957 :    
958 :     Merge of ml-lpt revisions for 110.64.
959 :    
960 :     The name of several ml-lpt-lib modules has changed:
961 :     Repair => AntlrRepair
962 :     StreamPos => AntlrStreamPos
963 :     ErrHandlerFn => AntlrErrHandler
964 :     EBNF => AntlrEBNF
965 :    
966 :     The ml-antlr specification format has changed: declarations such as
967 :     %tokens and nonterminal definitions can occur *multiple* times in the
968 :     same specification. The semantics are such that each new declaration
969 :     extends the previous ones. This does not apply to %start or %name,
970 :     of course.
971 :    
972 :     Importing a grammar via %import now includes *all* declarations in from
973 :     the imported grammar, except for %name, %entry, and %start. Tokens
974 :     and nonterminals can be dropped using the new %dropping clause of the
975 :     %import directive; the separate %drop and %extend have been removed.
976 :    
977 :     We now allow optional type annotations on nonterminals, using the %nonterms
978 :     directive as in ml-yacc.
979 :    
980 :     The refcell construct is now implemented using SML's regular reference
981 :     cells, so the :== and !! notation has been deprecated.
982 :    
983 :     The ml-antlr tool now does much more checking of specifications, and
984 :     its error messages have been greatly improved. Error repair for
985 :     generated parsers has been completely rewritten, and is now both
986 :     much faster and more accurate.
987 :    
988 :     ml-ulex is now more lenient with escape codes (non-SML-standard
989 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
990 :     Also, character classes may now include a "-" character at the beginning
991 :     as is standard in most other regexp tools.
992 :    
993 :     All of these changes are documented in the user guide, which has
994 :     been updated and improved with this merge.

1000 :     Description:
1001 :    
1002 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
1003 :     Significant changes in FLINT and the front end, mostly having to do
1004 :     with a reorganized system for handling primops. Various bug fixes
1005 :     and improvements in printing signatures.

1010 :     Description:
1011 :    
1012 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
1013 :     The ml-antlr specification format has changed: declarations such as
1014 :     %tokens and nonterminal definitions can occur *multiple* times in the
1015 :     same specification. The semantics are such that each new declaration
1016 :     extends the previous ones. Grammar extension constructs have also
1017 :     changed. We now allow type annotations on nonterminals. Finally,
1018 :     the refcell construct is now implemented using SML's regular reference
1019 :     cells, so the :== and !! notation has been deprecated. All of these
1020 :     changes will appear in the 110.64 user guide for ml-lpt.
1021 :    
1022 :     The ml-antlr tool now does much more checking of specifications, and
1023 :     its error messages have been greatly improved. There has also been
1024 :     some work on the error repair process for generated parsers, but this
1025 :     will be further improved in 110.64.

1030 :     Description:
1031 :    
1032 :     More Basis fixes: The Char.fromString (etc.) functions did not handle
1033 :     the "\uxxxx" escape sequence. There is still an outstanding bug with
1034 :     String.fromString the tail is a format escape. I added a comment to

1114 :     Description:
1115 :    
1116 :     Added preliminary support in MLRISC for Staged Allocation, a technique
1117 :     for specifying calling conventions (see
1118 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
1119 :     Initially, we plan to use this code to generate C calls for the AMD64.
1120 :    
1121 :     The staged allocation code base resides in MLRISC/staged-allocation,
1122 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

1128 :    
1129 :     Bug fix: when SaveCState was called with two values to save, a subsequent

1142 :    
1143 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
1144 :     of the range -128 ... 127. I've changed the code so that the range
1145 :     check is disabled. Only the low order 8 bits of the immediate operand

1187 :     Description:
1188 :    
1189 :     Brought ml-lpt manual up-to-date with the code. Many minor
1190 :     improvements to the tools, and a few minor bugfixes. Prepared
1191 :     ml-lpt-lib for integration with new UTF8 structure. Changed
1192 :     the interface for creating streams in ml-ulex (we now support
1193 :     stream creation from several kinds of sources). Overall, the
1194 :     tools are now quite stable, and their interfaces are unlikely to
1195 :     change in a way that would break compatibility. More work,
1196 :     however, is needed in the documentation.

1201 :     Description:
1202 :    
1203 :     Implemented library installer. Moved CM plugin code for
1204 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
1205 :     their respective trees. Implemented CM plugin for ml-ulex
1206 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
1207 :     and ml-antlr.
1208 :    
1209 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
1210 :     CM tools. (It turns out to be too messy to do otherwise because
1211 :     there is too much code that during installation relies on the presence
1212 :     of these tools -- resulting in a tricky ordering problem.)

1217 :     Description:
1218 :    
1219 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
1220 :     Modified CM's startup code to use shiftArgs as it processes
1221 :     command line arguments. This way, the init code in each .sml-file
1222 :     or library that is mentioned at the top level will see only
1223 :     those arguments that have not yet been processed at this point.
1224 :     In other words, the init code can "seize control" and process the
1225 :     remaining command line.

1292 :     Description:
1293 :    
1294 :     Added code to CM's "standard shell tool" implementation which
1295 :     causes it to tolerate (with a warning) the situation where the shell

1299 :     This makes it possible to, e.g., build ml-yacc from sources even if
1300 :     svn checkout messed up the time stamps on files in such a way that
1301 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
1302 :     be needed to re-process yacc.grm, but obviously it might not yet be
1303 :     available at that time.)

1342 :     Tag: release-110.60
1343 :     Description:
1344 :    
1345 :     New working release (110.60). NEW BOOTFILES!
1346 :    
1347 :     This is the first subversion-hosted release. There are also changes
1348 :     to the directory layout. Here is a table:
1349 :    
1350 :     (All pathnames are relative to the SML/NJ "root" directory.)
1351 :    
1352 :     config -> config
1353 :    
1354 :     src/cm -> base/cm
1355 :     src/compiler -> base/compiler
1356 :     src/runtime -> base/runtime
1357 :     src/system -> base/system
1358 :    
1359 :     src/cm/pgraph -> pgraph
1360 :    
1361 :     src/READMES -> base/READMES
1362 :     src/$notefile -> base/NOTES/$notefile
1363 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1364 :     MACOSXINSTALL WININSTALL
1365 :    
1366 :     src/smlnj-lib -> smlnj-lib
1367 :     src/MLRISC -> MLRISC
1368 :     ckit -> ckit
1369 :     src/cml -> cml
1370 :     src/eXene -> eXene
1371 :     src/heap2asm -> heap2asm
1372 :     src/lexgen -> lexgen
1373 :     src/ml-burg -> ml-burg
1374 :     src/ml-lex -> ml-lex
1375 :     src/ml-yacc -> ml-yacc
1376 :     src/ml-nlffi-lib -> nlffi/lib
1377 :     src/ml-nlffigen -> nlffi/gen
1378 :     src/smlnj-c -> smlnj-c
1379 :     src/tools/TraceDebugProf -> trace-debug-profile
1380 :    
1381 :     In addition, there is also a new
1382 :    
1383 :     ml-lpt
1384 :    
1385 :     directory containing two new program generator tools: ml-ulex and
1386 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1387 :     LL(k) parser generator). These tools are currently "beta-quality"
1388 :    
1389 :     The latest versios of the sources can now be obtained anonymously
1390 :     via subversion. For this, it is useful to first check out
1391 :    
1392 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1393 :    
1394 :     and put the resulting directory on your shell's PATH. This provides
1395 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
1396 :     and refresh-all.sh.
1397 :    
1398 :     To create a freshly checked-out copy of the sources, do
1399 :    
1400 :     checkout-all.sh [dir]
1401 :    
1402 :     where dir is the optional SML/NJ root directory (default is ".").
1403 :    
1404 :     This creates the above directory layout. Each subdirectory of
1405 :     the root is under individual subversion control. The stat-all.sh
1406 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
1407 :     each of these subtrees.

1410 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
1411 : blume 2155 Date: 2006/11/02 12:20:00 CST
1412 :     Description:
1413 :    
1414 :     Reorganized directory layout.
1415 :    
1416 :     This is a temporary solution, more reorganization is to come.
1417 :    
1418 :     The basic idea is to have a number of toplevel trees, each corresponding
1419 :     to a well-defined part of the overall system. Each part can be
1420 :     maintained individually, even in separate source repositories,
1421 :     although currently we still serve everything out of the main
1422 :     smlnj-gforge tree.
1423 :    
1424 :     Installer and and scripts have been updated to reflect the new
1425 :     layout. The installer (base/src/system/smlnj/installer) is now
1426 :     "scriptable" to avoid burning too much knowledge about the
1427 :     layout into SML source code. The main script used by the installer
1428 :     is in config/actions.
1429 :    
1430 :     The main change is that many of the subdirectories of what used to
1431 :     be known as "src" have moved to the toplevel. The "src" directory
1432 :     itself has moved down into a subtree called "base". (We may eventually
1433 :     get rid of the extra level of indirection represented by "src".)
1434 :    
1435 :     The layout is now as follows:
1436 :    
1437 :     toplevel tree name | default repository
1438 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1439 :     -------------------+----------------------------------------------------
1440 :     config | $gf/config/trunk
1441 :     |
1442 :     base | $gf/sml/trunk
1443 :     |
1444 :     smlnj-lib | $gf/smlnj-lib/trunk
1445 :     MLRISC | $gf/MLRISC/trunk
1446 :     |
1447 :     ml-yacc | $gf/ml-yacc/trunk
1448 :     ml-lex | $gf/ml-lex/trunk
1449 :     ml-burg | $gf/ml-burg/trunk
1450 :     lexgen | $gf/lexgen/trunk
1451 :     heap2asm | $gf/heap2asm/trunk
1452 :     |
1453 :     cml | $gf/cml/trunk
1454 :     eXene | $gf/eXene/trunk
1455 :     ckit | $gf/ckit/trunk
1456 :     nlffi | $gf/nlffi/trunk
1457 :     |
1458 :     smlnj-c | $gf/smlnj-c/trunk
1459 :    
1460 :     In $gf/admin there are a few useful shell scripts for checking out
1461 :     and maintaining the entire collection of trees:
1462 :    
1463 :     admin/checkout-all.sh [dir]
1464 :     -- optionally creates dir and checks out all trees from their
1465 :     default repositories; if dir is missing, checkout into .
1466 :     admin/refresh-all.sh [dir]
1467 :     -- looks at all trees (from the above list) in dir (default: .)
1468 :     and runs "svn update" if the tree exists and is under
1469 :     subversion control;
1470 :     non-existing or non-subversion trees are skipped
1471 :     admin/stat-all.sh [dir]
1472 :     -- like refresh-all.sh, but runs "svn stat" instead

1620 :     Hooked code for Darwin-specific Intel ABI into main compiler.
1621 :     (This is a temporary solution which relies on the fact that the

1652 :     Description:
1653 :    
1654 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1655 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1656 : blume 2155 at the time when config/preloads is processed, the library has to
1657 : mblume 1878 be referred to by another name. In 110.57 this would be
1658 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1659 :     to be valid as well.)

1714 :     Tag: blume-22051115-versiontool
1715 :     Description:
1716 :    
1717 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1718 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1719 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1720 :     it. Instead, it has the status of "user code", so it should use
1721 :     $/basis.cm to refer to the Basis library. (At least that's true for
1722 :     the purpose of bootstrapping the previous change. In the future it
1723 :     might make sense to have versiontool.cm refer to
1724 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1725 :     compiler itself uses.)
1726 :    
1727 :     Also patched src/system/testml to have it activate those extra anchor
1728 :     bindings in config/extrapathconfig.

1733 :     Tag: blume-22051115-libraries
1734 :     Description:
1735 :    
1736 :     This change affects the way the following libraries are tied into
1737 :     the system:
1738 :    
1739 :     $/basis.cm
1740 :     $/smlnj-lib.cm
1741 :     $/pp-lib.cm
1742 :     $/controls-lib.cm
1743 :     $/html-lib.cm
1744 :     $/ml-yacc-lib.cm
1745 :    
1746 :     These libraries are now internally (as seen from the source code
1747 :     of the implementation itself) known by the following names:
1748 :    
1749 :     $smlnj/basis/basis.cm
1750 :     $smlnj/smlnj-lib/smlnj-lib.cm
1751 :     $smlnj/smlnj-lib/pp-lib.cm
1752 :     $smlnj/smlnj-lib/controls-lib.cm
1753 :     $smlnj/smlnj-lib/html-lib.cm
1754 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1755 :    
1756 :     This makes it possible to work with code that requires different
1757 :     versions of these libraries, and which refers to these libraries using
1758 :     their "default" names (i.e., the first set of names above). In other
1759 :     words, one can un-define or re-define those default names without
1760 :     compromising the proper functioning of the compiler itself.
1761 :    
1762 :     A similar procedure had already been performed for several of the
1763 :     MLRISC libraries that are linked into the compiler. I did some
1764 :     cleanup on this code.
1765 :    
1766 :     A new file in the config directory (named extrapathconfig) is
1767 :     responsible for setting up path anchors that the compiler itself does
1768 :     not need, but that are typically required by user code.

1947 :     Tag: blume-20050516-redump-heap
1948 :     Description:
1949 :    
1950 :     Added mechanism for re-creating a heap file for the interactive system
1951 :     after configuration variables have been changed.
1952 :    
1953 :     CM.redump_heap : string -> unit
1954 :    
1955 :     This is much like SMLofNJ.exportML, but starting from the resulting
1956 : blume 2155 heap does not return to the caller of CM.redump_heap but
1957 : mblume 1792 restarts the interactive system from scratch. The original call of
1958 :     CM.redump_heap does not return but ends the interactive session.
1959 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1960 :    
1961 :     Internally, redump_heap winds the dynamic execution context back to
1962 :     the point where the original heap image was created and re-executes
1963 :     the heap image generation code in the boot code.

2079 :     Tag: blume-20050114-heap2exec
2080 :     Description:
2081 :    
2082 :     Implemented new (but still experimental) heap2exec facility. This is
2083 :     tested under Mac OS X and should work under Linux (will test shortly).
2084 :     It will probably also work on the Sparc (will test some time later).
2085 :    
2086 :     - removed old "HACKED_STANDALONE" hack from runtime
2087 :    
2088 :     To be able to test this, uncomment the request for "heap2asm" in
2089 :     config/targets prior to installation. (Notice that this is different
2090 :     from "heap2exec" mentioned below. Not a typo.)
2091 :    
2092 :     To perform an actual test, run the command
2093 :    
2094 :     $ bin/heap2exec heapfile execfile
2095 :    
2096 :     (You can put heap2exec on your shell's path.)
2097 :    
2098 :     For example, run
2099 :    
2100 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
2101 :    
2102 :     This will create a standalone executable called "mly" which you can
2103 :     then invoke directly as a command.

2128 :     (The parameter-passing part of the picture has not complete. But
2129 :     data structure access seems to work.)
2130 :    
2131 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
2132 :     (On the Mac, it is big-endian. And that's currently our only
2133 :     PPC platform.)

2248 :     Tag: blume-20041124-position
2249 :     Description:
2250 :    
2251 :     The compiler can now be compiled in a mode that makes structure Position
2252 :     equal to Int64. The default, however, is unchanged (Position = Int31)
2253 :     for the time being.
2254 :    
2255 :     To enable 64-bit positions, use the following procedure:
2256 :    
2257 :     1. Start sml
2258 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
2259 :     3. Type
2260 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
2261 :     4. Run CMB.make() as usual.
2262 :    
2263 :     This is barely tested. The only test so far was a little SML program
2264 :     counting the number of characters in an 8-gigabyte file by
2265 :     reading it character-by-character. That test was successful.
2266 :    
2267 :     In support of 64-bit positions, a number of new functions have been
2268 :     added to the runtime system.

2312 :     The date string is generated at bootstrap time (during makeml).
2313 :    
2314 :     - In a previous commit, fixed a minor issue with how polyequal is being
2315 :     translated. In particular, the code now "looks through" abstractions.
2316 :     This results in slightly fewer polyEqual warnings and hopefully slightly
2317 :     more efficient code. Important examples for where this matters are
2318 :     the new int64 and word64 types.

2333 :     Description:
2334 :    
2335 :     All the pieces of Word64 are now there, with the exception of the
2336 :     conversions from and to LargeWord. (Eventually these need to be identities,
2337 :     but for the time being they don't even make sense because LargeWord is
2338 :     32-bit wide.)
2339 :    
2340 :     Also started to add similar support for Int64, but major pieces of that
2341 :     are still missing.

2346 :     Tag: blume-20041111-word64
2347 :     Description:
2348 :    
2349 :     Structure Word64 is now (almost) complete, word literals and patterns
2350 :     seem to work. There are a few odd pieces missing. In particular,
2351 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2352 :     at the moment.
2353 :    
2354 :     Making Word64 official would mean that LargeWord becomes Word64. But
2355 :     this requires extreme care because most word-word conversions have to
2356 :     go through LargeWord, so making a mistake means loss of efficiency or
2357 :     worse. Eventually there will be a solution similar to (but actually
2358 :     simpler than) what I did with IntInf.

2390 :     - Changend config/srcarchiveurl from a file just

2392 :     shell script code. The code has access to the $VERSION variable.
2393 :     - Made corresponding changes to config/install.sh and config/unpack.
2394 :     - Default contents of config/srcarchiveurl uses $VERSION and
2395 :     normally does not have to be edited to reflect a version change.
2396 :    
2397 :     (As a result, a version change can be done by just editing
2398 :     config/version, the rest is now automatic.)

2438 :     Tag: blume-20041020-standalone-backtrace
2439 :     Description:
2440 :    
2441 :     Added a mechanism for getting back-trace information from standalone
2442 :     programs. Here is how it works:
2443 :    
2444 :     1. The part of the program from which you want to get backtrace
2445 :     information (usually the whole program) should be wrapped with
2446 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
2447 :     main program could be modified from something like
2448 :    
2449 :     fun main (pgm, args) = ...
2450 :    
2451 :     to
2452 :    
2453 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2454 :    
2455 :     2. To be able to access BackTrace.monitor, you have to add
2456 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
2457 :     main function.
2458 :    
2459 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2460 :     CM might have created in the past for your project).
2461 :    
2462 :     4. Build the system using this command line:
2463 :    
2464 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2465 :     myprog.cm MyProg.main myprog
2466 :    
2467 :     instead of the usual
2468 :    
2469 :     ml-build myprog.cm MyProg.main myprog
2470 :    
2471 :     I changed a library name:
2472 :    
2473 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2474 :    
2475 :     New libraries:
2476 :    
2477 :     $smlnj-tdp/back-trace.cm
2478 :     -- when loaded causes the back-trace plugin to be installed
2479 :     $smlnj-tdp/coverage.cm
2480 :     -- when loaded causes the coverage plugin to be installed

2496 :     Description:
2497 :    
2498 :     * Test coverage tool added!
2499 :     * Further reorganization of tracing-, debugging-, and profiling support:
2500 :    
2501 :     - moved original BTImp -- now called BackTrace -- into a separate
2502 :     library called $/trace-debug-profile.cm
2503 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2504 :     - only the instrumentation mechanism is now left in the compiler proper
2505 :     - BackTrace module is a plugin which is NOT plugged in by default
2506 :     - Coverage module is another such plugin
2507 :    
2508 :     To get the benefits of any of these plugin modules, the code in

2510 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2511 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2512 :    
2513 :     Plugins are selected at link time. (Pre-compiled instrumented code
2514 :     can be re-loaded with different plugins in effect.) When an

2517 :    
2518 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2519 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2520 :     To enable the coverage plugin, load the same library and invoke
2521 :     Coverage.install().
2522 :    
2523 :     Back-traces are generated automatically on uncaught exceptions and
2524 :     when the code in question explicitly invokes BackTrace.trigger().
2525 :    
2526 :     Coverage (and execution frequency-) information must be queried

2628 :    
2629 :     * Moved the "version" magic into its own little library under

2636 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2637 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2638 :     Also, loading the versiontool does not work when rebuilding the system

2644 :     Tag: blume-20040929-autoversion
2645 :     Description:
2646 :    
2647 :     Implemented some CM magic to have
2648 :     file src/compiler/TopLevel/main/version.sml
2649 :     generated automagically.
2650 :     The version is taken from two files: config/version and config/release.
2651 :     The first is expected to contain a two-part version number such as 110.49.
2652 :     The second should contain a single number, but it may be missing.
2653 :    
2654 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2655 :     time the version tool is loaded (which is the first time you say CMB.make),
2656 :     then the tool will increment the value stored in config/release every
2657 :     time CMB.make is invoked.
2658 :    
2659 :     The binfile format is now insensitive to anything beyond the first
2660 :     two components of a version number, so bumping the release does not render
2661 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2662 :     during development without invalidating existing binfiles.
2663 :    
2664 :     In any case, every CMB.make updates the date information in version.sml.
2665 :     (This is the date that is printed in the banner.)

2678 :     Tag: blume-20040927-controls
2679 :     Description:
2680 :    
2681 :     Added two pieces of functionality to the Controls interface:
2682 :    
2683 :     1. val save'restore: 'a control -> unit -> unit
2684 :    
2685 :     grabs the current value of the control in stage 1 and restores it
2686 :     in stage 2.
2687 :    
2688 :     2. val set' : 'a control * 'a -> unit -> unit
2689 :    
2690 :     stores the given value into the control in stage 2 (i.e., delayed)
2691 :     but does all error checking in stage 1.
2692 :     (This is for string controls that need to do parse their argument --
2693 :     something that might fail. In some cases, notably in CM, one
2694 :     already knows the intended argument but wants to delay the actual
2695 :     assignment until a time when error recovery would be more difficult.)
2696 :    
2697 :     Changed the handling of controls in tool arguments to classes "sml" and
2698 :     "lazysml":
2699 :     - use Controls.save'restore as a more robust way of restoring the
2700 :     old value (in particular: without having to re-parse the string)
2701 :     - use controls to handle the "overload" keyword in the init group
2702 :     (I believe this change actually fixes a long-standing obscure bug.)

2707 :     Tag: blume-20040927-lazysml
2708 :     Description:
2709 :    
2710 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2711 :     difference to "sml" is that compilation is done with Control.lazysml
2712 :     set to true. A source of class "lazysml" is automatically recognized
2713 :     by a file name suffix of ".lml".
2714 :    
2715 :     In addition to the above feature, the original class "sml" now also
2716 :     supports a tool argument "lazy" which has the same effect. As a
2717 :     result, the following three lines are equivalent:
2718 :    
2719 :     foo.sml : lazysml
2720 :     foo.sml : sml (lazy)
2721 :     foo.sml (lazy)
2722 :    
2723 :     The setting goes into effect both during parsing and during
2724 :     compilation. The original setting is restored right after parsing and
2725 :     after compilation, respectively.
2726 :    
2727 :     In addition to all the above, there is also a general mechanism to set
2728 :     ANY of the "controls" that are available at the command line via
2729 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2730 :     apply as well. (In fact, "lazy" is implemented as a special case of
2731 :     the general mechanism.)
2732 :    
2733 :     The .cm file syntax uses a new keyword tool argument called "with".
2734 :     There are several ways of indicating the desired settings:
2735 :    
2736 :     foo.sml (with:parser.quotations=true)
2737 :     foo.sml (with:(name:parser.quotations value:true))
2738 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2739 :     foo.sml (with:(name1=value1 name2=value2 ...))
2740 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2741 :    
2742 :     etc.
2743 :    
2744 :     Another possible abbreviation is to leave out the =v or value:v part
2745 :     if the name refers to a boolean control (in which case the value is
2746 :     taken to be true). Thus, one could get lazy sml also by saying:
2747 :    
2748 :     foo.sml (with:parser.lazy-keyword=true)
2749 :     foo.sml (with:parser.lazy-keyword)
2750 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2751 :     foo.sml (with:(name:parser.lazy-keyword))

3052 :     - added ccall_maxargspace to machspec (to implement the above)
3053 :     - made "make" commend in CM's "make" tool configurable
3054 :     - added option (default: on) for passing the name of the SML/NJ's "bin"

3056 :    
3057 :     make <options> SMLNJ_BINDIR=<dir> <target>

3103 :     Description:
3104 :    
3105 :     Changed the interface of structures Timer and Unix to match the most
3106 :     recent Basis spec.
3107 :    
3108 :     In the case of Unix there still seems to be an open/weird issue:
3109 :    
3110 :     The {text,bin}{In,Out}streamOf functions are supposed to create
3111 :     fresh streams whenever they are called -- as opposed to have them
3112 :     return the same stream every time. This design is supposed to
3113 :     prevent space leaks caused by proc values hanging on to streams.
3114 :    
3115 :     The reap function, on the other hand, is supposed to close the
3116 :     streams. This cannot be done without having a handle on the
3117 :     stream in proc after all...
3118 :    
3119 :     I took the liberty to implement the following stopgap solution:
3120 :    
3121 :     The proc value hangs on to the most recently created stream(s).
3122 :     Reap closes those. If either or both of the two streams hadn't
3123 :     been created at all yet, then reap will close the corresponding
3124 :     file descriptors directly.
3125 :    
3126 :     PS: I don't understand the original space leak argument anymore. If
3127 :     a proc hangs on to the imperative stream, then I/O operations on those
3128 :     will advance the state of the cached stream and avoid the space leak.

3141 :     Tag: blume-20040525-group-owner
3142 :     Description:
3143 :    
3144 :     CM now ignores (but still accepts) the "owner" information in group
3145 :     descriptions. The owner of a group is its next enclosing
3146 :     library. Each group must have a unique owner. (There is a virtual
3147 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
3148 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
3149 :     and CM would check that such a declaration is correct. The new scheme
3150 :     is to have CM check that for each group there is precisely one owning
3151 :     library.
3152 :    
3153 :     The advantage of the new scheme is that the programmer no longer needs
3154 :     to maintain the somewhat annoying owner information. The downside is
3155 :     that CM cannot enforce the ownership rule across multiple runs of
3156 :     CM.make. Fortunately, enclosing the same group in two different
3157 :     libraries A and B which are not part of the same program does not
3158 :     cause real problems.

3177 :     Description:
3178 :    
3179 :     Arranged for ml-build to clean up after itself a little bit better.
3180 :     The script generates a temporary SML source file and compiles it using
3181 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
3182 :     gets rid of those at the end, so they don't accumulate under .cm.
3183 :    
3184 :     This required a minor change to install.sh because the name of the

3204 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
3205 :     for the voluminous patch!
3206 :    
3207 :     (I have not tested this patch under win32 yet.)
3208 :    
3209 : mblume 1490 Here is David's e-mail:
3210 :    
3211 :     Hi,
3212 :    
3213 :     Attached to this email you find a diff against sml/nj 110.45
3214 :     that will enable socket support under Windows.
3215 :    
3216 :     To apply the patch (using unix or cygwin)
3217 :     1) gunzip runtime.diff.gz
3218 :     2) "cd" into "src/runtime" in the source tree of a fresh
3219 :     110.45 installation.
3220 :     3) patch -p 1 < [your/path/to]runtime.diff
3221 :    
3222 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
3223 :     I only ran a few tests for basic socket client functionality
3224 :     (which worked fine). Especially the functions that use ioctl
3225 : mblume 1490 are not tested at all and might not work (see below).
3226 :    
3227 :     I implemented this since we want to move to a newer version of sml/nj
3228 :     but need socket support in order to use it. This is the first time I
3229 :     even had a look at the sml/nj source, so please review my changes
3230 :     before making this part of the distribution! Here are a few issues
3231 : blume 2155 that I think might be better for someone to solve who is more
3232 : mblume 1490 familiar with the sml/nj source (and socket programming):
3233 :    
3234 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
3235 :     exception since I could not figure out what the windows equivalent
3236 :     of these functions is
3237 :    
3238 :     - In sockets-osdep.h there are a some #include statements that are
3239 :     only used in a few files that include sockets-osdep.h
3240 :    
3241 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
3242 :     does not process its return value since I don't know how to
3243 :     report an error upwards.
3244 :    
3245 :     - It would probably be good to have a call to WSACleanup() when
3246 : blume 2155 the library is unloaded (if there is such a possibility).
3247 : mblume 1490 Otherwise I think Windows will take care of this automatically
3248 :     when the process finishes.
3249 :    
3250 :     - I used ioctlsocket() as a replacement for ioctl() but I have
3251 :     no idea if that is actually the proper replacement on Windows.
3252 :    
3253 :     - All these issues are marked in the code by "FIXME" comments.
3254 :    
3255 : blume 2155 We use sml/nj extensively in our products and are quite happy
3256 :     with it. I hope this contribution will help you.
3257 : mblume 1490
3258 :     Keep up the good work!

3335 :     Description:
3336 :    
3337 :     Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
3338 :     of SML/NJ. The problem is that
3339 :    
3340 :     lib = dlopen(NULL, ...)
3341 :     f = dlsym(lib, "malloc");
3342 :    
3343 : blume 2155 does not work on Windows unless we explicitly export symbols
3344 :     such as 'malloc' during linking. We fixed this by explicitly
3345 : allenleung 1468 exporting the required symbols with the magic gcc incantation:
3346 :    
3347 :     -Wl,--export-all cygwin.def
3348 :    
3349 :     where cygwin.def is a file containing all the symbols that
3350 : blume 2155 we wish to export.
3351 : allenleung 1468
3352 : blume 2155 I suspect this is a Windows problem and we'll have to
3353 :     do the same (somehow with windows compilers) when
3354 : allenleung 1468 we build the native win32 version with the system
3355 : blume 2155 calls LoadLibrary/GetProcAddress.

3425 :     Eliminated the "dont_move_libraries" directive in config/targets.
3426 :     (The mechanism was broken and could not be fixed easily. Moreover,
3427 :     there does not seem to be any reason not to move all libraries into
3428 :     lib during installation. I originally implemented this directive as a
3429 :     backward-compatibility feature when I first introduced the new CM.
3430 :     Now that things have been stable for a long time and going back to the
3431 :     old CM is not an option, there is no reason to keep it around.)

3480 :     Tag: blume-20030926-ppautoload
3481 :     Description:
3482 :    
3483 :     I modified the read-eval-print loop so that the autoloader gets
3484 :     invoked whenever the prettyprinter tries to look up a symbol that
3485 :     is not currently defined in the toplevel environment but which
3486 :     appears in CM's autoload registry. As a result, we see far fewer of
3487 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3488 :    
3489 :     In addition to this I tried to clean up some pieces of the Basis
3490 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3491 :     instances of these ?.Foo.Bar.xxx names from being printed.
3492 :    
3493 :     The mechanism that picks names for types still needs some work, though.
3494 :     (Right now it seems that if there is a type A.t which is defined to
3495 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3496 :     "?.B.u" although the perhaps more sensible solution would be to use
3497 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3498 :     a chain of DEFtycs not farther than there are corresponding toplevel
3499 :     names in the current environment.)

3505 :     Description:
3506 :    
3507 :     Another installer tweak: All the ML code for the installer is now
3508 :     compiled during CMB.make and put into a little library called
3509 :     $smlnj/installer.cm. The installation then simply invokes
3510 :    
3511 :     sml -m $smlnj/installer.cm
3512 :    
3513 :     and everything happens automagically.
3514 :    
3515 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3516 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3517 :     and BINDIR.
3518 :    
3519 :     The new scheme guarantees that the ML code responsible for the installation
3520 :     is in sync with the APIs of the main system. Also, the installer is
3521 :     somewhat faster because the installer script is precompiled.

3533 :     structure.

3538 :     Tag: blume-20030924-sockets
3539 :     Description:
3540 :    
3541 :     1. Fixed SOCKET API and implementation to match Basis spec.
3542 :     This required changing the internal representation of sockets to one
3543 :     that remembers (for each socket file descriptor) whether it is currently
3544 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3545 :     call is made only if the state actually needs to change).
3546 :    
3547 :     2. OS-specific details of sockets were moved into separate files, thus
3548 :     making it possible to unify the bulk of the socket implementations
3549 :     between Unix and Win32.
3550 :    
3551 :     3. CML's socket API changed accordingly.
3552 :     (Note that we need to remove non-blocking functions from this API
3553 :     since they are redundant in the case of CML!)
3554 :    
3555 :     4. CML's socket implementation now makes use of non-blocking functions
3556 :     provided by Basis, thus removing all OS-dependent code from this part
3557 :     of CML.
3558 :    
3559 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3672 :     Description:
3673 :    
3674 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3675 :     Modified config/install.bat to take advantage of it. Also modified
3676 :     config/install.sh (and called it config/new-install.sh) to take advantage
3677 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3678 :     independent.)
3679 :    
3680 :     The installer can now install everything under Win32
3681 :     as well as under *nix as long as it compiles.
3682 :    
3683 :     Other changes:
3684 :    
3685 :     - made CML compile again under Win32
3686 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3687 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3688 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3689 :     same as type int; under Win32 it isn't
3690 :     - fixed some slice-related problems in the win32-specific parts of CML
3691 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3692 :     (under Win32, the volume name is case-insensitive, and the
3693 :     OS.Path code compares volume names for equality)

3699 :     Description:
3700 :    
3701 :     Made Win32 version of OS.FileSys.fullPath return current directory
3702 :     when given an empty string. This is what the spec says, and incidentally,
3703 :     CM depends on it. (CM otherwise goes into an infinite loop in certain
3704 :     cases when presented with the name of a non-existing .cm file.)

3710 : mblume 1350 Description:
3711 :    
3712 :     1. Changed interface to vectors and arrays in Basis to match
3713 :     (draft) Basis spec.
3714 :     2. Added signatures and implementations of slices according to
3715 :     Basis spec.
3716 :     3. Edited source code throughout the system to make it compile again
3717 :     under 1. and 2. (In some cases code had to be added to have it
3718 :     match the new signatures.)
3719 :     4. MLRISC should be backward-compatible: the copies of the originals
3720 :     of files that needed to change under 3. were retained, the .cm files
3721 :     check the compiler version number and use old versions when
3722 :     appropriate.
3723 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3724 :     dirstream -> string option (in accordance with Basis spec).
3725 :     6. When generating code that counts lines, ml-lex used function
3726 :     CharVector.foldli, taking advantage of its old interface.
3727 :     This has been replaced with the corresponding code from
3728 :     CharVectorSlice. (html-lex must be re-lexed!)
3729 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3730 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3731 :     8. Removed temporary additions (fromInternal, toInternal) from the
3732 :     (now obsolete) IntInf in smlnj-lib/Util.
3733 :     9. Cleaned up structure Byte.
3734 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3735 :     Cleaned/corrected implementation of Date.
3736 :     (Still need to check for correctness; implement better canonicalizeDate.)
3737 :     11. Added "scan" to signature IEEE_REAL.
3738 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3739 :     mod and rem when second operand is 2 (for parity checks).]
3740 :     13. Changed representation of type Time.time, using a single IntInf.int
3741 :     value counting microseconds. This considerably simplified the
3742 :     implementation of structure Time. We now support negative time
3743 :     values; scan and fromString handle signs.
3744 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3745 :     ArraySlice).

3750 :     Tag: blume-20030828-intinf
3751 :     Description:
3752 :    
3753 :     This is a major update which comes with a version number bump
3754 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3755 :     and an implementation of IntInf in the Basis.
3756 :    
3757 :     There are a fairly large number of related changes and updates throughout
3758 :     the system:
3759 :    
3760 :     Basis:
3761 :     - Implemented IntInf.
3762 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3763 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3764 : mblume 1347 - Added FixedInt as a synonym for Int32.
3765 :    
3766 :     compiler:
3767 :     * Added support for a built-in intinf type.
3768 :     - literals
3769 :     - pattern matching
3770 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3771 :     - overloading on literals and operations
3772 :    
3773 :     This required adding a primitive type intinf, some additional
3774 :     primops, and implementations for several non-trivial intinf
3775 :     operations in Core. (The intinf type is completely abstract
3776 :     to the compiler; all operations get delegated back to the Core.)
3777 :    
3778 :     * Intinf equality is handled by polyequal. However, the compiler
3779 :     does not print its usual warning in this case (since polyequal
3780 :     is the right thing to do there).
3781 :    
3782 :     * Improved the organization of structure InlineT.
3783 :    
3784 :     * A word about conversion primops:
3785 :     If conversions involving intinf do not cancel out during
3786 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3787 : mblume 1347 Since all core access must be resolved already during the FLINT
3788 :     translate phase, it would be too late a the time of CPS contract
3789 : mblume 1348 to add new Core calls. For this reason, conversion primops
3790 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3791 :     they are supposed to convert, and 2. the Core function that
3792 :     can help with this conversion if necessary. If CPS contract
3793 : mblume 1348 eliminates a primop, then the associated Core function becomes
3794 :     dead and goes away. Intinf conversion primops that do not get
3795 :     eliminated by CPS contract get rewritten into calls of their
3796 :     core functions by a separate, new phase.
3797 : mblume 1347
3798 :     interactive system:
3799 :     - Control.Print.intinfDepth controls max length of intinf constants
3800 :     being printed. (Analogous to Control.Print.stringDepth.)
3801 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3802 :     duplicates; replaced some of the code with code that makes better
3803 :     use of library functionality.
3804 :    
3805 :     CM:
3806 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3807 :     are no longer silent.
3808 :    
3809 :     CKIT:
3810 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3811 :     in favor of LargeInt -- which is now the same as IntInf.
3812 :     CKIT-knowledgable people should check whether this is what's
3813 :     intended and otherwise change things back to using Int32 or
3814 :     FixedInt.
3815 :    
3816 :     Throughout the code:
3817 : mblume 1348 Started using IntInf.int literals and built-in operations
3818 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3827 :     Merging changes from the mcz-branch development branch into trunk.
3828 :     These changes involve replacement of the emulated old prettyprinter
3829 :     interface with direct use of the SML/NJ Lib PP library, and fixing
3830 :     of a couple of bugs (895, 1186) relating to error messages. A new

3832 :     has been added.

3837 :     Tag: blume-20030811-windows
3838 :     Description:
3839 :    
3840 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3841 :    
3842 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3843 :    
3844 :     This patch restores SML/NJ's ability to run under win32. There are a
3845 :     number of changes, including fixes for several bugs that had gone
3846 :     unnoticed until now:
3847 :    
3848 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3849 :     trying to run the win32 version from within cygwin.)
3850 :    
3851 :     - There are a number of simple .bat scripts that substitute for their
3852 :     corresponding Unix shell-scripts. (See below.)
3853 :    
3854 :     - The internals of ml-build have been modified slightly. The main
3855 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3856 :     using OS.Process.system, the ML process delegates this task back
3857 :     to the script. Otherwise problems arise in mixed environments such
3858 :     as Cygwin where scripts look and work like Unix scripts, but
3859 :     where OS.Process.system cannot run them.
3860 :    
3861 :     - In CM, the srcpath pickler used native pathname syntax -- which
3862 :     is incorrect in the case of cross-compilation. The new pickle format
3863 :     is independent of platform-specific naming conventions.
3864 :    
3865 :     - Path configuration files (such as lib/pathconfig) can now choose
3866 :     between native and standard syntax. Placing a line of the form
3867 :    
3868 :     standard!
3869 :    
3870 :     into the file causes all subsequent paths to be interpreted using
3871 :     CM standard pathname syntax (= Unix conventions); a line
3872 :    
3873 :     native!
3874 :    
3875 :     switches back to native style. This was needed so that
3876 :     path config files can be written portably, see src/system/pathconfig.
3877 :    
3878 :     - Runtime system:
3879 :    
3880 :     - win32-filesys.c: get_file_time and set_file_time now
3881 :     access modification time, not creation time.
3882 :    
3883 :     - I/O code made aware of new array representation.
3884 :    
3885 :     - Bug fixes in X86.prim.masm.
3886 :    
3887 :     - src/system/makeml made aware of win32. (For use under cygwin
3888 :     and other Unix-environments for windows.)
3889 :    
3890 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3891 :     which caused BinIO.inputAll to fail consistently.
3892 :    
3893 :     .bat scripts:
3894 :    
3895 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3896 :    
3897 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3898 :     applications (sml, ml-yacc, ml-lex).
3899 :     - ml-build.bat: analogous to ml-build.
3900 :     - config\install.bat: Analogous to config/install.sh. This requires
3901 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3902 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3903 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3904 :     and the bootfile hierarchy must have been unpacked under
3905 :     sml.boot.x86-win32.
3906 :     The script is very primitive and does a poor job at error checking.
3907 :     It only installs the base system, ml-lex, and ml-yacc. No other
3908 :     libraries are being installed (i.e., you get only those that
3909 :     are part of the compiler.)
3910 :     - link-sml.bat: analogous to .link-sml, but not currently used
3911 :    
3912 :     Unrelated bug fixes:
3913 :    
3914 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3915 :     types.
3916 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3917 :     otherwise.)

3941 :     Description:
3942 :    
3943 :     Two changes:
3944 :    
3945 :     1. Added a flag for controlling whether non-exhaustive bindings will
3946 :     be treated as errors (default is false).
3947 :     2. Cleaned up the *entire* source tree so that CMB.make goes through
3948 :     without a single non-exhaustive match- or bind warning.

3953 :     Tag: blume-20030517-absyn
3954 :     Description:
3955 :    
3956 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3957 :    
3958 :     This mainly affects the quality of error messages. However, some
3959 :     of the code is now more straightforward than before. (Treatment of
3960 :     the above four constructs in translate.sml is much simpler than
3961 :     the "macro-expansion" that was going on before. Plus, the mach-
3962 :     compiler no longer gets invoked just to be able to compile an
3963 :     if-expression.)
3964 :    
3965 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3966 :     interactive loop.

3973 :    
3974 : blume 2155 Ported the runtime system to cygwin, which uses the unix

3976 :    
3977 : blume 2155 o getnetbyname, getnetbyaddr: these functions seem to be missing in
3978 : allenleung 1327 the Cygwin library.
3979 :     o Ctrl-C handling may be flaky.
3980 :     o Windows system calls and Windows I/O are not supported.
3981 :    
3982 :     A new set of binfiles is located at:
3983 :    
3984 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3985 :    
3986 :     This is only needed for bootstrapping the cygwin version of smlnj.
3987 :     Other x86 versions can use the existing binfiles.

4029 :     change their identity (e.g., by getting unlinked and recreated by some
4030 :     text editor such as vi). There might be a better/cheaper/cleaner way

4111 :     Description:
4112 :

4114 :     other clients can set up backtracing support.

4119 :     Tag: blume-20020625-fpmax
4120 :     Description:
4121 :    
4122 :     Fixed a bug in translation of INLMAX (and INLMIN) for the floating-point
4123 :     case. (The sense of the isNaN test was reversed -- which made min and
4124 :     max always return their first argument.)

4137 :     Tag: blume-20020610-ieeereal
4138 :     Description:
4139 :    
4140 :     I back-ported my implementation of IEEEReal.fromString from the
4141 :     idlbasis-devel branch so that we can test it.
4142 :    
4143 :     Another small change is that ppDec tries to give more information
4144 :     than just "<sig>" in the case of functors. However, this code is
4145 :     broken in some mysterious way if the functor's body's signature
4146 :     has not been declared by ascription but gets inferred from the
4147 :     implementation. This needs fixing...

4153 :     Description:
4154 :    
4155 :     Resurrected SMLofNJ.Internals.BTrace.mode. (It accidentally fell by
4156 :     the wayside when I switched over to using Controls everywhere.)

4165 :     the fall-through and target blocks obvious.

4172 :    
4173 :     John tweaked yesterday's fix for 1131 to handle an out-of-memory
4174 :     situation that comes up when allocating huge arrays.
