1 : blume 2237 This is the HISTORY file for the SML/NJ repository.
2 : dbm 570
3 :     An entry should be made for _every_ commit to the repository.
4 :     The entries in this file will be used when creating the README
5 :     for new versions, so keep that in mind when writing the
6 :     description.

281 :    
282 :     - Aaron: fixed a number of bugs in ml-ulex.
283 :     - Matthias:
284 :     - added CM control "cm.force-tools"; this is false by default;
285 :     when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
286 :     will be forced to run regardless of whether or not their targets
287 :     are up-to-date

292 :     Name: Matthias Blume (http://www.tti-c.org/blume/)

294 :     Description:
295 :    
296 :     After Aaron Turon's bug fix for ml-ulex (handling the ^ character
297 :     in legacy mode), re-ran the lexer generator on all lex input files
298 :     and committed the results.
299 :    
300 :     This should fix the problem with ckit and nlffi that was reported
301 :     by Vesa A. Norrman.

313 :     Date: 2007/05/31 14:55:00 CDT
314 :     Revision: 2650
315 :     Description:
316 :    
317 :     3rd merge of base from primop-branch-3 into the trunk.
318 :     Additional bug fixes included:
319 :    
320 :     * Timer.cpu_timer, etc. type printing corrected (by making
321 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
322 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
323 :     Stefan Monnier)
324 :    
325 :     ----------------------------------------------------------------------
326 : blume 2645 Name: Matthias Blume (http://www.tti-c.org/blume/)
327 :     Date: 2007/05/31 11:40:00 CDT
328 :     Description:
329 :    
330 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
331 :    
332 :     Also, changed the handling of "no core access": When translate.sml
333 :     needs access to a core exception at a time when the core has not
334 :     been set up yet (this only happens when compiling system/smlnj/init/*),
335 :     then don't bother generating the corresponding tests.
336 :    
337 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
338 :     the exception. Unfortunately, that confuses the plambda type checker.
339 :     Moreover, it does not do any good, because at runtime we don't expect
340 :     such an exception to be ever raised. (The code in system/smlnj/init/*
341 :     has to be written very carefully with this in mind!)

347 :    
348 :     Added FSQRT instructions for the AMD64 code generator.

351 : blume 2626 Name: Matthias Blume (http://www.tti-c.org/blume/)
352 :     Date: 2007/05/29 19:00:00 CDT
353 :     Description:
354 :    
355 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
356 :     with an explicit test for zero division. This should fixes several
357 :     regressions and makes it possible for downstream optimization phases
358 :     to treat these operations as "pure" when they are applied to unsigned
359 :     operands.
360 :    
361 :     ----------------------------------------------------------------------
362 : mrainey 2622 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
363 :     Date: 2007/05/29
364 :     Description:
365 :    
366 :     Added the new MLRISC code generator for the AMD64. This version,
367 :     in contrast to the previous one, uses SSE registers and instructions
368 :     for all floating-point computations.

371 : jhr 2613 Name: John Reppy (http://www.cs.uchicago.edu/~jhr)
372 : jhr 2617 Date: 2007/05/29
373 : jhr 2613 Description:
374 :    
375 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
376 :     for bugs #1415 and #1416. We also now correctly handle format characters that
377 :     lie outside the specified set.

380 : blume 2610 Name: Matthias Blume (http://www.tti-c.org/blume/)
381 :     Date: 2007/05/23 22:30:00 CDT
382 :     Description:
383 :    
384 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
385 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
386 :    
387 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
388 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
389 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
390 :     while running CMB.make. The point is that the single symbol
391 :     NO_PLUGINS is definde in all three cases.)
392 :    
393 :     I changed the three locations within the sources that get compiled
394 :     during CMB.make where ml-yacc or ml-lex input is processed: When
395 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
396 :     is bypassed.
397 :    
398 :     When bootstrapping new versions of the compiler, there can be
399 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
400 :     are not available or otherwise not operational. In this case one can
401 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
402 :     do so, the following command should be issued at the interactive
403 :     prompt:
404 :    
405 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
406 :    
407 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
408 :     files that normally would be generated by ml-yacc and ml-lex.
409 :     (Copies of these files are in the repository.)

424 : blume 2589 Date: 2007/05/23 09:50:00 CDT
425 :     Description:
426 :    
427 :     Changed the installation mechanism for CM tool plugins. These are
428 :     just libaries and now get installed like ordinary libaries.
429 :    
430 :     There are now a number of new installation targets that give some
431 :     fine-grain control over what classes and suffixes are known, and what
432 :     they will map to.
433 :     See config/targets for details.
434 :    
435 :     The code that caused plugin installation as part of running a
436 :     tool's "build" script has been removed. (The build script is for
437 :     building, not for installing.)

442 :     Description:
443 :    
444 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
445 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
446 :     CM fail if a shell tool reports a non-success exit status. If
447 :     the control is set to true, then CM will press on after tool failures
448 :     in the event that the target files exist (even though they are
449 :     considered outdated). Turning the control to true can be useful for
450 :     bootstrapping.

455 :     Description:
456 :    
457 :     Merge of ml-lpt revisions for 110.64.
458 :    
459 :     The name of several ml-lpt-lib modules has changed:
460 :     Repair => AntlrRepair
461 :     StreamPos => AntlrStreamPos
462 :     ErrHandlerFn => AntlrErrHandler
463 :     EBNF => AntlrEBNF
464 :    
465 :     The ml-antlr specification format has changed: declarations such as
466 :     %tokens and nonterminal definitions can occur *multiple* times in the
467 :     same specification. The semantics are such that each new declaration
468 :     extends the previous ones. This does not apply to %start or %name,
469 :     of course.
470 :    
471 :     Importing a grammar via %import now includes *all* declarations in from
472 :     the imported grammar, except for %name, %entry, and %start. Tokens
473 :     and nonterminals can be dropped using the new %dropping clause of the
474 :     %import directive; the separate %drop and %extend have been removed.
475 :    
476 :     We now allow optional type annotations on nonterminals, using the %nonterms
477 :     directive as in ml-yacc.
478 :    
479 :     The refcell construct is now implemented using SML's regular reference
480 :     cells, so the :== and !! notation has been deprecated.
481 :    
482 :     The ml-antlr tool now does much more checking of specifications, and
483 :     its error messages have been greatly improved. Error repair for
484 :     generated parsers has been completely rewritten, and is now both
485 :     much faster and more accurate.
486 :    
487 :     ml-ulex is now more lenient with escape codes (non-SML-standard
488 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
489 :     Also, character classes may now include a "-" character at the beginning
490 :     as is standard in most other regexp tools.
491 :    
492 :     All of these changes are documented in the user guide, which has
493 :     been updated and improved with this merge.

561 :    
562 :     More Basis fixes: The Char.fromString (etc.) functions did not handle

643 :     Date: 2007/02/26
644 :     Description:
645 :    
646 :     Added preliminary support in MLRISC for Staged Allocation, a technique
647 :     for specifying calling conventions (see
648 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
649 :     Initially, we plan to use this code to generate C calls for the AMD64.
650 :    
651 :     The staged allocation code base resides in MLRISC/staged-allocation,
652 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

658 :    
659 :     Bug fix: when SaveCState was called with two values to save, a subsequent

672 :    
673 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
674 :     of the range -128 ... 127. I've changed the code so that the range
675 :     check is disabled. Only the low order 8 bits of the immediate operand

716 :     Date: 2007/01/31
717 :     Description:
718 :    
719 :     Brought ml-lpt manual up-to-date with the code. Many minor
720 :     improvements to the tools, and a few minor bugfixes. Prepared
721 :     ml-lpt-lib for integration with new UTF8 structure. Changed
722 :     the interface for creating streams in ml-ulex (we now support
723 :     stream creation from several kinds of sources). Overall, the
724 :     tools are now quite stable, and their interfaces are unlikely to
725 :     change in a way that would break compatibility. More work,
726 :     however, is needed in the documentation.

730 : blume 2298 Date: 2007/02/01 10:05:00 CST
731 :     Description:
732 :    
733 :     Implemented library installer. Moved CM plugin code for
734 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
735 :     their respective trees. Implemented CM plugin for ml-ulex
736 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
737 :     and ml-antlr.
738 :    
739 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
740 :     CM tools. (It turns out to be too messy to do otherwise because
741 :     there is too much code that during installation relies on the presence
742 :     of these tools -- resulting in a tricky ordering problem.)

747 :     Description:
748 :    
749 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
750 :     Modified CM's startup code to use shiftArgs as it processes
751 :     command line arguments. This way, the init code in each .sml-file
752 :     or library that is mentioned at the top level will see only
753 :     those arguments that have not yet been processed at this point.
754 :     In other words, the init code can "seize control" and process the
755 :     remaining command line.

811 :     Description:
812 :    
813 :     Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to
814 :     get the c_cc termios data copied correctly. Also moved the allocation
815 :     of the string to avoid problems if it caused a GC.

821 :     Date: 2006/12/08 09:50:00 CST
822 :     Description:
823 :    
824 :     Added code to CM's "standard shell tool" implementation which
825 :     causes it to tolerate (with a warning) the situation where the shell
826 :     command fails (e.g., due to the shell command's non-existence)
827 :     as long as all target files exist.
828 :    
829 :     This makes it possible to, e.g., build ml-yacc from sources even if
830 :     svn checkout messed up the time stamps on files in such a way that
831 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
832 :     be needed to re-process yacc.grm, but obviously it might not yet be
833 :     available at that time.)

839 :    
840 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
841 :     recvVecFromNB' in the SOCKET signature. This error is actually
842 :     in the SML Basis specification too.

855 :     Description:
856 :    
857 :     Use Say.vsay for printing the "[autoloading]" message, so

859 :     to suppress them.

872 :     Tag: release-110.60
873 :     Description:
874 :    
875 :     New working release (110.60). NEW BOOTFILES!
876 :    
877 :     This is the first subversion-hosted release. There are also changes
878 :     to the directory layout. Here is a table:
879 :    
880 :     (All pathnames are relative to the SML/NJ "root" directory.)
881 :    
882 :     config -> config
883 :    
884 :     src/cm -> base/cm
885 :     src/compiler -> base/compiler
886 :     src/runtime -> base/runtime
887 :     src/system -> base/system
888 :    
889 :     src/cm/pgraph -> pgraph
890 :    
891 :     src/READMES -> base/READMES
892 :     src/$notefile -> base/NOTES/$notefile
893 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
894 :     MACOSXINSTALL WININSTALL
895 :    
896 :     src/smlnj-lib -> smlnj-lib
897 :     src/MLRISC -> MLRISC
898 :     ckit -> ckit
899 :     src/cml -> cml
900 :     src/eXene -> eXene
901 :     src/heap2asm -> heap2asm
902 :     src/lexgen -> lexgen
903 :     src/ml-burg -> ml-burg
904 :     src/ml-lex -> ml-lex
905 :     src/ml-yacc -> ml-yacc
906 :     src/ml-nlffi-lib -> nlffi/lib
907 :     src/ml-nlffigen -> nlffi/gen
908 :     src/smlnj-c -> smlnj-c
909 :     src/tools/TraceDebugProf -> trace-debug-profile
910 :    
911 :     In addition, there is also a new
912 :    
913 :     ml-lpt
914 :    
915 :     directory containing two new program generator tools: ml-ulex and
916 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
917 :     LL(k) parser generator). These tools are currently "beta-quality"
918 :    
919 :     The latest versios of the sources can now be obtained anonymously
920 :     via subversion. For this, it is useful to first check out
921 :    
922 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
923 :    
924 :     and put the resulting directory on your shell's PATH. This provides
925 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
926 :     and refresh-all.sh.
927 :    
928 :     To create a freshly checked-out copy of the sources, do
929 :    
930 :     checkout-all.sh [dir]
931 :    
932 :     where dir is the optional SML/NJ root directory (default is ".").
933 :    
934 :     This creates the above directory layout. Each subdirectory of
935 :     the root is under individual subversion control. The stat-all.sh
936 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
937 :     each of these subtrees.
938 :

941 : blume 2155 Date: 2006/11/02 12:20:00 CST
942 :     Description:
943 :    
944 :     Reorganized directory layout.
945 :    
946 :     This is a temporary solution, more reorganization is to come.
947 :    
948 :     The basic idea is to have a number of toplevel trees, each corresponding
949 :     to a well-defined part of the overall system. Each part can be
950 :     maintained individually, even in separate source repositories,
951 :     although currently we still serve everything out of the main
952 :     smlnj-gforge tree.
953 :    
954 :     Installer and and scripts have been updated to reflect the new
955 :     layout. The installer (base/src/system/smlnj/installer) is now
956 :     "scriptable" to avoid burning too much knowledge about the
957 :     layout into SML source code. The main script used by the installer
958 :     is in config/actions.
959 :    
960 :     The main change is that many of the subdirectories of what used to
961 :     be known as "src" have moved to the toplevel. The "src" directory
962 :     itself has moved down into a subtree called "base". (We may eventually
963 :     get rid of the extra level of indirection represented by "src".)
964 :    
965 :     The layout is now as follows:
966 :    
967 :     toplevel tree name | default repository
968 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
969 :     -------------------+----------------------------------------------------
970 :     config | $gf/config/trunk
971 :     |
972 :     base | $gf/sml/trunk
973 :     |
974 :     smlnj-lib | $gf/smlnj-lib/trunk
975 :     MLRISC | $gf/MLRISC/trunk
976 :     |
977 :     ml-yacc | $gf/ml-yacc/trunk
978 :     ml-lex | $gf/ml-lex/trunk
979 :     ml-burg | $gf/ml-burg/trunk
980 :     lexgen | $gf/lexgen/trunk
981 :     heap2asm | $gf/heap2asm/trunk
982 :     |
983 :     cml | $gf/cml/trunk
984 :     eXene | $gf/eXene/trunk
985 :     ckit | $gf/ckit/trunk
986 :     nlffi | $gf/nlffi/trunk
987 :     |
988 :     smlnj-c | $gf/smlnj-c/trunk
989 :    
990 :     In $gf/admin there are a few useful shell scripts for checking out
991 :     and maintaining the entire collection of trees:
992 :    
993 :     admin/checkout-all.sh [dir]
994 :     -- optionally creates dir and checks out all trees from their
995 :     default repositories; if dir is missing, checkout into .
996 :     admin/refresh-all.sh [dir]
997 :     -- looks at all trees (from the above list) in dir (default: .)
998 :     and runs "svn update" if the tree exists and is under
999 :     subversion control;
1000 :     non-existing or non-subversion trees are skipped
1001 :     admin/stat-all.sh [dir]
1002 :     -- like refresh-all.sh, but runs "svn stat" instead

1039 :     * Fixed a bug in the SyncVar polling functions (iGetPoll,
1040 :     mTakePoll, and mGetPoll) that could lead to livelock.

1149 :    
1150 :     Hooked code for Darwin-specific Intel ABI into main compiler.
1151 :     (This is a temporary solution which relies on the fact that the
1152 :     compiler itself does not use NLFFI. Eventually we need to divorce
1153 :     intel mac from generic x86 unix code and make separate sets of binaries.)

1182 :     Description:
1183 :    
1184 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1185 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1186 : blume 2155 at the time when config/preloads is processed, the library has to
1187 : mblume 1878 be referred to by another name. In 110.57 this would be
1188 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1189 :     to be valid as well.)

1245 :     Description:
1246 :    
1247 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1248 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1249 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1250 :     it. Instead, it has the status of "user code", so it should use
1251 :     $/basis.cm to refer to the Basis library. (At least that's true for
1252 :     the purpose of bootstrapping the previous change. In the future it
1253 :     might make sense to have versiontool.cm refer to
1254 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1255 :     compiler itself uses.)

1257 :     Also patched src/system/testml to have it activate those extra anchor
1258 :     bindings in config/extrapathconfig.

1286 :     This makes it possible to work with code that requires different
1287 :     versions of these libraries, and which refers to these libraries using
1288 :     their "default" names (i.e., the first set of names above). In other
1289 :     words, one can un-define or re-define those default names without
1290 :     compromising the proper functioning of the compiler itself.
1291 :    
1292 :     A similar procedure had already been performed for several of the
1293 :     MLRISC libraries that are linked into the compiler. I did some
1294 :     cleanup on this code.
1295 :    
1296 :     A new file in the config directory (named extrapathconfig) is
1297 :     responsible for setting up path anchors that the compiler itself does
1298 :     not need, but that are typically required by user code.

1478 :     Description:
1479 :    
1480 :     Added mechanism for re-creating a heap file for the interactive system
1481 :     after configuration variables have been changed.
1482 :    
1483 :     CM.redump_heap : string -> unit
1484 :    
1485 :     This is much like SMLofNJ.exportML, but starting from the resulting
1486 : blume 2155 heap does not return to the caller of CM.redump_heap but
1487 : mblume 1792 restarts the interactive system from scratch. The original call of
1488 :     CM.redump_heap does not return but ends the interactive session.
1489 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1490 :    
1491 :     Internally, redump_heap winds the dynamic execution context back to
1492 :     the point where the original heap image was created and re-executes
1493 :     the heap image generation code in the boot code.

1610 :     Description:
1611 :    
1612 :     Implemented new (but still experimental) heap2exec facility. This is
1613 :     tested under Mac OS X and should work under Linux (will test shortly).
1614 :     It will probably also work on the Sparc (will test some time later).
1615 :    
1616 :     - removed old "HACKED_STANDALONE" hack from runtime
1617 :    
1618 :     To be able to test this, uncomment the request for "heap2asm" in
1619 :     config/targets prior to installation. (Notice that this is different
1620 :     from "heap2exec" mentioned below. Not a typo.)
1621 :    
1622 :     To perform an actual test, run the command
1623 :    
1624 :     $ bin/heap2exec heapfile execfile
1625 :    
1626 :     (You can put heap2exec on your shell's path.)
1627 :    
1628 :     For example, run
1629 :    
1630 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1631 :    
1632 :     This will create a standalone executable called "mly" which you can
1633 :     then invoke directly as a command.

1682 :     Windows style pathname, so problems arise when SMLNJ_HOME is set
1683 :     to a Windows style pathname. _run-sml now converts SMLNJ_HOME

1778 :     Tag: blume-20041124-position
1779 :     Description:
1780 :    
1781 :     The compiler can now be compiled in a mode that makes structure Position
1782 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1783 :     for the time being.
1784 :    
1785 :     To enable 64-bit positions, use the following procedure:
1786 :    
1787 :     1. Start sml
1788 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1789 :     3. Type
1790 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1791 :     4. Run CMB.make() as usual.
1792 :    
1793 :     This is barely tested. The only test so far was a little SML program
1794 :     counting the number of characters in an 8-gigabyte file by
1795 :     reading it character-by-character. That test was successful.
1796 :    
1797 :     In support of 64-bit positions, a number of new functions have been
1798 :     added to the runtime system.

1840 :    
1841 :     - Stripped down the versiontool: It now only handles the version number.
1842 :     The date string is generated at bootstrap time (during makeml).
1843 :    
1844 :     - In a previous commit, fixed a minor issue with how polyequal is being
1845 :     translated. In particular, the code now "looks through" abstractions.
1846 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1847 :     more efficient code. Important examples for where this matters are
1848 :     the new int64 and word64 types.

1863 :     Description:
1864 :    
1865 :     All the pieces of Word64 are now there, with the exception of the
1866 :     conversions from and to LargeWord. (Eventually these need to be identities,
1867 :     but for the time being they don't even make sense because LargeWord is
1868 :     32-bit wide.)
1869 :    
1870 :     Also started to add similar support for Int64, but major pieces of that
1871 :     are still missing.

1876 :     Tag: blume-20041111-word64
1877 :     Description:
1878 :    
1879 :     Structure Word64 is now (almost) complete, word literals and patterns
1880 :     seem to work. There are a few odd pieces missing. In particular,
1881 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1882 :     at the moment.
1883 :    
1884 :     Making Word64 official would mean that LargeWord becomes Word64. But
1885 :     this requires extreme care because most word-word conversions have to
1886 :     go through LargeWord, so making a mistake means loss of efficiency or
1887 :     worse. Eventually there will be a solution similar to (but actually
1888 :     simpler than) what I did with IntInf.

1923 :     - Made corresponding changes to config/install.sh and config/unpack.
1924 :     - Default contents of config/srcarchiveurl uses $VERSION and
1925 :     normally does not have to be edited to reflect a version change.
1926 :    
1927 :     (As a result, a version change can be done by just editing
1928 :     config/version, the rest is now automatic.)

1968 :     Tag: blume-20041020-standalone-backtrace
1969 :     Description:
1970 :    
1971 :     Added a mechanism for getting back-trace information from standalone
1972 :     programs. Here is how it works:
1973 :    
1974 :     1. The part of the program from which you want to get backtrace
1975 :     information (usually the whole program) should be wrapped with
1976 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
1977 :     main program could be modified from something like
1978 :    
1979 :     fun main (pgm, args) = ...
1980 :    
1981 :     to
1982 :    
1983 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1984 :    
1985 :     2. To be able to access BackTrace.monitor, you have to add
1986 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
1987 :     main function.
1988 :    
1989 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1990 :     CM might have created in the past for your project).
1991 :    
1992 :     4. Build the system using this command line:
1993 :    
1994 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1995 :     myprog.cm MyProg.main myprog
1996 :    
1997 :     instead of the usual
1998 :    
1999 :     ml-build myprog.cm MyProg.main myprog
2000 :    
2001 :     I changed a library name:
2002 :    
2003 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2004 :    
2005 :     New libraries:
2006 :    
2007 :     $smlnj-tdp/back-trace.cm
2008 :     -- when loaded causes the back-trace plugin to be installed
2009 :     $smlnj-tdp/coverage.cm
2010 :     -- when loaded causes the coverage plugin to be installed

2026 :     Description:
2027 :    
2028 :     * Test coverage tool added!
2029 :     * Further reorganization of tracing-, debugging-, and profiling support:
2030 :    
2031 :     - moved original BTImp -- now called BackTrace -- into a separate
2032 :     library called $/trace-debug-profile.cm
2033 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2034 :     - only the instrumentation mechanism is now left in the compiler proper
2035 :     - BackTrace module is a plugin which is NOT plugged in by default
2036 :     - Coverage module is another such plugin
2037 :    
2038 :     To get the benefits of any of these plugin modules, the code in
2039 :     question must be compiled with tdp instrumentation turned on. This
2040 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2041 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2042 :    
2043 :     Plugins are selected at link time. (Pre-compiled instrumented code
2044 :     can be re-loaded with different plugins in effect.) When an
2045 :     instrumented module is linked, whatever plugins are at that time
2046 :     enabled will come into effect for that module.
2047 :    
2048 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2049 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2050 :     To enable the coverage plugin, load the same library and invoke
2051 :     Coverage.install().
2052 :    
2053 :     Back-traces are generated automatically on uncaught exceptions and
2054 :     when the code in question explicitly invokes BackTrace.trigger().
2055 :    
2056 :     Coverage (and execution frequency-) information must be queried
2057 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2097 :    
2098 :     Made some minor modifications to elabcore.sml to have source regions

2106 :     Description:
2107 :    
2108 :     Fixed handling of keywords in .cm files: After seeing "is" the lexer
2109 :     treats subsequent occurrences of "group", "library", "source", "is",
2110 :     "*", and "-" as ordinary identifiers rather than keywords.
2111 :    
2112 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool
2113 :     is supposed to accept a tool argument called "source", but this did
2114 :     not work because of the clash with the keyword.

2158 :    
2159 :     * Moved the "version" magic into its own little library under

2166 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2167 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2168 :     Also, loading the versiontool does not work when rebuilding the system
2169 :     because CM is not properly initialized at that time.

2174 :     Tag: blume-20040929-autoversion
2175 :     Description:
2176 :    
2177 :     Implemented some CM magic to have
2178 :     file src/compiler/TopLevel/main/version.sml
2179 :     generated automagically.
2180 :     The version is taken from two files: config/version and config/release.
2181 :     The first is expected to contain a two-part version number such as 110.49.
2182 :     The second should contain a single number, but it may be missing.
2183 :    
2184 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2185 :     time the version tool is loaded (which is the first time you say CMB.make),
2186 :     then the tool will increment the value stored in config/release every
2187 :     time CMB.make is invoked.
2188 :    
2189 :     The binfile format is now insensitive to anything beyond the first
2190 :     two components of a version number, so bumping the release does not render
2191 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2192 :     during development without invalidating existing binfiles.
2193 :    
2194 :     In any case, every CMB.make updates the date information in version.sml.
2195 :     (This is the date that is printed in the banner.)

2208 :     Tag: blume-20040927-controls
2209 :     Description:
2210 :    
2211 :     Added two pieces of functionality to the Controls interface:
2212 :    
2213 :     1. val save'restore: 'a control -> unit -> unit
2214 :    
2215 :     grabs the current value of the control in stage 1 and restores it
2216 :     in stage 2.
2217 :    
2218 :     2. val set' : 'a control * 'a -> unit -> unit
2219 :    
2220 :     stores the given value into the control in stage 2 (i.e., delayed)
2221 :     but does all error checking in stage 1.
2222 :     (This is for string controls that need to do parse their argument --
2223 :     something that might fail. In some cases, notably in CM, one
2224 :     already knows the intended argument but wants to delay the actual
2225 :     assignment until a time when error recovery would be more difficult.)
2226 :    
2227 :     Changed the handling of controls in tool arguments to classes "sml" and
2228 :     "lazysml":
2229 :     - use Controls.save'restore as a more robust way of restoring the
2230 :     old value (in particular: without having to re-parse the string)
2231 :     - use controls to handle the "overload" keyword in the init group
2232 :     (I believe this change actually fixes a long-standing obscure bug.)

2237 :     Tag: blume-20040927-lazysml
2238 :     Description:
2239 :    
2240 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2241 :     difference to "sml" is that compilation is done with Control.lazysml
2242 :     set to true. A source of class "lazysml" is automatically recognized
2243 :     by a file name suffix of ".lml".
2244 :    
2245 :     In addition to the above feature, the original class "sml" now also
2246 :     supports a tool argument "lazy" which has the same effect. As a
2247 :     result, the following three lines are equivalent:
2248 :    
2249 :     foo.sml : lazysml
2250 :     foo.sml : sml (lazy)
2251 :     foo.sml (lazy)
2252 :    
2253 :     The setting goes into effect both during parsing and during
2254 :     compilation. The original setting is restored right after parsing and
2255 :     after compilation, respectively.
2256 :    
2257 :     In addition to all the above, there is also a general mechanism to set
2258 :     ANY of the "controls" that are available at the command line via
2259 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2260 :     apply as well. (In fact, "lazy" is implemented as a special case of
2261 :     the general mechanism.)
2262 :    
2263 :     The .cm file syntax uses a new keyword tool argument called "with".
2264 :     There are several ways of indicating the desired settings:
2265 :    
2266 :     foo.sml (with:parser.quotations=true)
2267 :     foo.sml (with:(name:parser.quotations value:true))
2268 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2269 :     foo.sml (with:(name1=value1 name2=value2 ...))
2270 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2271 :    
2272 :     etc.
2273 :    
2274 :     Another possible abbreviation is to leave out the =v or value:v part
2275 :     if the name refers to a boolean control (in which case the value is
2276 :     taken to be true). Thus, one could get lazy sml also by saying:
2277 :    
2278 :     foo.sml (with:parser.lazy-keyword=true)
2279 :     foo.sml (with:parser.lazy-keyword)
2280 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2281 :     foo.sml (with:(name:parser.lazy-keyword))

2582 :     - added ccall_maxargspace to machspec (to implement the above)
2583 :     - made "make" commend in CM's "make" tool configurable
2584 :     - added option (default: on) for passing the name of the SML/NJ's "bin"

2586 :    
2587 :     make <options> SMLNJ_BINDIR=<dir> <target>

2633 :     Description:
2634 :    
2635 :     Changed the interface of structures Timer and Unix to match the most
2636 :     recent Basis spec.
2637 :    
2638 :     In the case of Unix there still seems to be an open/weird issue:
2639 :    
2640 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2641 :     fresh streams whenever they are called -- as opposed to have them
2642 :     return the same stream every time. This design is supposed to
2643 :     prevent space leaks caused by proc values hanging on to streams.
2644 :    
2645 :     The reap function, on the other hand, is supposed to close the
2646 :     streams. This cannot be done without having a handle on the
2647 :     stream in proc after all...
2648 :    
2649 :     I took the liberty to implement the following stopgap solution:
2650 :    
2651 :     The proc value hangs on to the most recently created stream(s).
2652 :     Reap closes those. If either or both of the two streams hadn't
2653 :     been created at all yet, then reap will close the corresponding
2654 :     file descriptors directly.
2655 :    
2656 :     PS: I don't understand the original space leak argument anymore. If
2657 :     a proc hangs on to the imperative stream, then I/O operations on those
2658 :     will advance the state of the cached stream and avoid the space leak.

2671 :     Tag: blume-20040525-group-owner
2672 :     Description:
2673 :    
2674 :     CM now ignores (but still accepts) the "owner" information in group
2675 :     descriptions. The owner of a group is its next enclosing
2676 :     library. Each group must have a unique owner. (There is a virtual
2677 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2678 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2679 :     and CM would check that such a declaration is correct. The new scheme
2680 :     is to have CM check that for each group there is precisely one owning
2681 :     library.
2682 :    
2683 :     The advantage of the new scheme is that the programmer no longer needs
2684 :     to maintain the somewhat annoying owner information. The downside is
2685 :     that CM cannot enforce the ownership rule across multiple runs of
2686 :     CM.make. Fortunately, enclosing the same group in two different
2687 :     libraries A and B which are not part of the same program does not
2688 :     cause real problems.

2707 :     Description:
2708 :    
2709 :     Arranged for ml-build to clean up after itself a little bit better.
2710 :     The script generates a temporary SML source file and compiles it using
2711 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
2712 :     gets rid of those at the end, so they don't accumulate under .cm.
2713 :    
2714 :     This required a minor change to install.sh because the name of the

2734 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
2735 :     for the voluminous patch!
2736 :    
2737 :     (I have not tested this patch under win32 yet.)
2738 :    
2739 : mblume 1490 Here is David's e-mail:
2740 :    
2741 :     Hi,
2742 :    
2743 :     Attached to this email you find a diff against sml/nj 110.45
2744 :     that will enable socket support under Windows.
2745 :    
2746 :     To apply the patch (using unix or cygwin)
2747 :     1) gunzip runtime.diff.gz
2748 :     2) "cd" into "src/runtime" in the source tree of a fresh
2749 :     110.45 installation.
2750 :     3) patch -p 1 < [your/path/to]runtime.diff
2751 :    
2752 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2753 :     I only ran a few tests for basic socket client functionality
2754 :     (which worked fine). Especially the functions that use ioctl
2755 : mblume 1490 are not tested at all and might not work (see below).
2756 :    
2757 :     I implemented this since we want to move to a newer version of sml/nj
2758 :     but need socket support in order to use it. This is the first time I
2759 :     even had a look at the sml/nj source, so please review my changes
2760 :     before making this part of the distribution! Here are a few issues
2761 : blume 2155 that I think might be better for someone to solve who is more
2762 : mblume 1490 familiar with the sml/nj source (and socket programming):
2763 :    
2764 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2765 :     exception since I could not figure out what the windows equivalent
2766 :     of these functions is
2767 :    
2768 :     - In sockets-osdep.h there are a some #include statements that are
2769 :     only used in a few files that include sockets-osdep.h
2770 :    
2771 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2772 :     does not process its return value since I don't know how to
2773 :     report an error upwards.
2774 :    
2775 :     - It would probably be good to have a call to WSACleanup() when
2776 : blume 2155 the library is unloaded (if there is such a possibility).
2777 : mblume 1490 Otherwise I think Windows will take care of this automatically
2778 :     when the process finishes.
2779 :    
2780 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2781 :     no idea if that is actually the proper replacement on Windows.
2782 :    
2783 :     - All these issues are marked in the code by "FIXME" comments.
2784 :    
2785 : blume 2155 We use sml/nj extensively in our products and are quite happy
2786 :     with it. I hope this contribution will help you.
2787 : mblume 1490
2788 :     Keep up the good work!

2956 :     (The mechanism was broken and could not be fixed easily. Moreover,
2957 :     there does not seem to be any reason not to move all libraries into
2958 :     lib during installation. I originally implemented this directive as a
2959 :     backward-compatibility feature when I first introduced the new CM.
2960 :     Now that things have been stable for a long time and going back to the
2961 :     old CM is not an option, there is no reason to keep it around.)

3010 :     Tag: blume-20030926-ppautoload
3011 :     Description:
3012 :    
3013 :     I modified the read-eval-print loop so that the autoloader gets
3014 :     invoked whenever the prettyprinter tries to look up a symbol that
3015 :     is not currently defined in the toplevel environment but which
3016 :     appears in CM's autoload registry. As a result, we see far fewer of
3017 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3018 :    
3019 :     In addition to this I tried to clean up some pieces of the Basis
3020 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3021 :     instances of these ?.Foo.Bar.xxx names from being printed.
3022 :    
3023 :     The mechanism that picks names for types still needs some work, though.
3024 :     (Right now it seems that if there is a type A.t which is defined to
3025 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3026 :     "?.B.u" although the perhaps more sensible solution would be to use
3027 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3028 :     a chain of DEFtycs not farther than there are corresponding toplevel
3029 :     names in the current environment.)

3035 :     Description:
3036 :    
3037 :     Another installer tweak: All the ML code for the installer is now
3038 :     compiled during CMB.make and put into a little library called
3039 :     $smlnj/installer.cm. The installation then simply invokes
3040 :    
3041 :     sml -m $smlnj/installer.cm
3042 :    
3043 :     and everything happens automagically.
3044 :    
3045 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3046 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3047 :     and BINDIR.
3048 :    
3049 :     The new scheme guarantees that the ML code responsible for the installation
3050 :     is in sync with the APIs of the main system. Also, the installer is
3051 :     somewhat faster because the installer script is precompiled.

3060 :     but excludes all non-blocking operations. Defined SOCKET (in Basis)
3061 :     and CML_SOCKET in terms of SYNCHRONOUS_SOCKET. Removed superfluous

3063 :     structure.

3068 :     Tag: blume-20030924-sockets
3069 :     Description:
3070 :    
3071 :     1. Fixed SOCKET API and implementation to match Basis spec.
3072 :     This required changing the internal representation of sockets to one
3073 :     that remembers (for each socket file descriptor) whether it is currently
3074 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3075 :     call is made only if the state actually needs to change).
3076 :    
3077 :     2. OS-specific details of sockets were moved into separate files, thus
3078 :     making it possible to unify the bulk of the socket implementations
3079 :     between Unix and Win32.
3080 :    
3081 :     3. CML's socket API changed accordingly.
3082 :     (Note that we need to remove non-blocking functions from this API
3083 :     since they are redundant in the case of CML!)
3084 :    
3085 :     4. CML's socket implementation now makes use of non-blocking functions
3086 :     provided by Basis, thus removing all OS-dependent code from this part
3087 :     of CML.
3088 :    
3089 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3202 :     Description:
3203 :    
3204 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3205 :     Modified config/install.bat to take advantage of it. Also modified
3206 :     config/install.sh (and called it config/new-install.sh) to take advantage
3207 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3208 :     independent.)
3209 :    
3210 :     The installer can now install everything under Win32
3211 :     as well as under *nix as long as it compiles.
3212 :    
3213 :     Other changes:
3214 :    
3215 :     - made CML compile again under Win32
3216 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3217 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3218 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3219 :     same as type int; under Win32 it isn't
3220 :     - fixed some slice-related problems in the win32-specific parts of CML
3221 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3222 :     (under Win32, the volume name is case-insensitive, and the
3223 :     OS.Path code compares volume names for equality)

3240 : mblume 1350 Description:
3241 :    
3242 :     1. Changed interface to vectors and arrays in Basis to match
3243 :     (draft) Basis spec.
3244 :     2. Added signatures and implementations of slices according to
3245 :     Basis spec.
3246 :     3. Edited source code throughout the system to make it compile again
3247 :     under 1. and 2. (In some cases code had to be added to have it
3248 :     match the new signatures.)
3249 :     4. MLRISC should be backward-compatible: the copies of the originals
3250 :     of files that needed to change under 3. were retained, the .cm files
3251 :     check the compiler version number and use old versions when
3252 :     appropriate.
3253 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3254 :     dirstream -> string option (in accordance with Basis spec).
3255 :     6. When generating code that counts lines, ml-lex used function
3256 :     CharVector.foldli, taking advantage of its old interface.
3257 :     This has been replaced with the corresponding code from
3258 :     CharVectorSlice. (html-lex must be re-lexed!)
3259 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3260 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3261 :     8. Removed temporary additions (fromInternal, toInternal) from the
3262 :     (now obsolete) IntInf in smlnj-lib/Util.
3263 :     9. Cleaned up structure Byte.
3264 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3265 :     Cleaned/corrected implementation of Date.
3266 :     (Still need to check for correctness; implement better canonicalizeDate.)
3267 :     11. Added "scan" to signature IEEE_REAL.
3268 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3269 :     mod and rem when second operand is 2 (for parity checks).]
3270 :     13. Changed representation of type Time.time, using a single IntInf.int
3271 :     value counting microseconds. This considerably simplified the
3272 :     implementation of structure Time. We now support negative time
3273 :     values; scan and fromString handle signs.
3274 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3275 :     ArraySlice).

3280 :     Tag: blume-20030828-intinf
3281 :     Description:
3282 :    
3283 :     This is a major update which comes with a version number bump
3284 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3285 :     and an implementation of IntInf in the Basis.
3286 :    
3287 :     There are a fairly large number of related changes and updates throughout
3288 :     the system:
3289 :    
3290 :     Basis:
3291 :     - Implemented IntInf.
3292 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3293 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3294 : mblume 1347 - Added FixedInt as a synonym for Int32.
3295 :    
3296 :     compiler:
3297 :     * Added support for a built-in intinf type.
3298 :     - literals
3299 :     - pattern matching
3300 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3301 :     - overloading on literals and operations
3302 :    
3303 :     This required adding a primitive type intinf, some additional
3304 :     primops, and implementations for several non-trivial intinf
3305 :     operations in Core. (The intinf type is completely abstract
3306 :     to the compiler; all operations get delegated back to the Core.)
3307 :    
3308 :     * Intinf equality is handled by polyequal. However, the compiler
3309 :     does not print its usual warning in this case (since polyequal
3310 :     is the right thing to do there).
3311 :    
3312 :     * Improved the organization of structure InlineT.
3313 :    
3314 :     * A word about conversion primops:
3315 :     If conversions involving intinf do not cancel out during
3316 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3317 : mblume 1347 Since all core access must be resolved already during the FLINT
3318 :     translate phase, it would be too late a the time of CPS contract
3319 : mblume 1348 to add new Core calls. For this reason, conversion primops
3320 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3321 :     they are supposed to convert, and 2. the Core function that
3322 :     can help with this conversion if necessary. If CPS contract
3323 : mblume 1348 eliminates a primop, then the associated Core function becomes
3324 :     dead and goes away. Intinf conversion primops that do not get
3325 :     eliminated by CPS contract get rewritten into calls of their
3326 :     core functions by a separate, new phase.
3327 : mblume 1347
3328 :     interactive system:
3329 :     - Control.Print.intinfDepth controls max length of intinf constants
3330 :     being printed. (Analogous to Control.Print.stringDepth.)
3331 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3332 :     duplicates; replaced some of the code with code that makes better
3333 :     use of library functionality.
3334 :    
3335 :     CM:
3336 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3337 :     are no longer silent.
3338 :    
3339 :     CKIT:
3340 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3341 :     in favor of LargeInt -- which is now the same as IntInf.
3342 :     CKIT-knowledgable people should check whether this is what's
3343 :     intended and otherwise change things back to using Int32 or
3344 :     FixedInt.
3345 :    
3346 :     Throughout the code:
3347 : mblume 1348 Started using IntInf.int literals and built-in operations
3348 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3355 :     Description:

3357 :     Merging changes from the mcz-branch development branch into trunk.
3358 :     These changes involve replacement of the emulated old prettyprinter
3359 :     interface with direct use of the SML/NJ Lib PP library, and fixing
3360 :     of a couple of bugs (895, 1186) relating to error messages. A new

3362 :     has been added.

3366 : mblume 1342 Date: 2003/08/11 15:45:00 CDT
3367 :     Tag: blume-20030811-windows
3368 :     Description:
3369 :    
3370 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3371 :    
3372 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3373 :    
3374 :     This patch restores SML/NJ's ability to run under win32. There are a
3375 :     number of changes, including fixes for several bugs that had gone
3376 :     unnoticed until now:
3377 :    
3378 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3379 :     trying to run the win32 version from within cygwin.)
3380 :    
3381 :     - There are a number of simple .bat scripts that substitute for their
3382 :     corresponding Unix shell-scripts. (See below.)
3383 :    
3384 :     - The internals of ml-build have been modified slightly. The main
3385 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3386 :     using OS.Process.system, the ML process delegates this task back
3387 :     to the script. Otherwise problems arise in mixed environments such
3388 :     as Cygwin where scripts look and work like Unix scripts, but
3389 :     where OS.Process.system cannot run them.
3390 :    
3391 :     - In CM, the srcpath pickler used native pathname syntax -- which
3392 :     is incorrect in the case of cross-compilation. The new pickle format
3393 :     is independent of platform-specific naming conventions.
3394 :    
3395 :     - Path configuration files (such as lib/pathconfig) can now choose
3396 :     between native and standard syntax. Placing a line of the form
3397 :    
3398 :     standard!
3399 :    
3400 :     into the file causes all subsequent paths to be interpreted using
3401 :     CM standard pathname syntax (= Unix conventions); a line
3402 :    
3403 :     native!
3404 :    
3405 :     switches back to native style. This was needed so that
3406 :     path config files can be written portably, see src/system/pathconfig.
3407 :    
3408 :     - Runtime system:
3409 :    
3410 :     - win32-filesys.c: get_file_time and set_file_time now
3411 :     access modification time, not creation time.
3412 :    
3413 :     - I/O code made aware of new array representation.
3414 :    
3415 :     - Bug fixes in X86.prim.masm.
3416 :    
3417 :     - src/system/makeml made aware of win32. (For use under cygwin
3418 :     and other Unix-environments for windows.)
3419 :    
3420 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3421 :     which caused BinIO.inputAll to fail consistently.
3422 :    
3423 :     .bat scripts:
3424 :    
3425 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3426 :    
3427 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3428 :     applications (sml, ml-yacc, ml-lex).
3429 :     - ml-build.bat: analogous to ml-build.
3430 :     - config\install.bat: Analogous to config/install.sh. This requires
3431 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3432 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3433 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3434 :     and the bootfile hierarchy must have been unpacked under
3435 :     sml.boot.x86-win32.
3436 :     The script is very primitive and does a poor job at error checking.
3437 :     It only installs the base system, ml-lex, and ml-yacc. No other
3438 :     libraries are being installed (i.e., you get only those that
3439 :     are part of the compiler.)
3440 :     - link-sml.bat: analogous to .link-sml, but not currently used
3441 :    
3442 :     Unrelated bug fixes:
3443 :    
3444 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3445 :     types.
3446 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3447 :     otherwise.)

3471 :     Description:
3472 :    
3473 :     Two changes:
3474 :    
3475 :     1. Added a flag for controlling whether non-exhaustive bindings will
3476 :     be treated as errors (default is false).
3477 :     2. Cleaned up the *entire* source tree so that CMB.make goes through
3478 :     without a single non-exhaustive match- or bind warning.

3484 :     Description:
3485 :    
3486 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3487 :    
3488 :     This mainly affects the quality of error messages. However, some
3489 :     of the code is now more straightforward than before. (Treatment of
3490 :     the above four constructs in translate.sml is much simpler than
3491 :     the "macro-expansion" that was going on before. Plus, the mach-
3492 :     compiler no longer gets invoked just to be able to compile an
3493 :     if-expression.)
3494 :    
3495 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3496 :     interactive loop.

3503 :    
3504 : blume 2155 Ported the runtime system to cygwin, which uses the unix

3508 : allenleung 1327 the Cygwin library.
3509 :     o Ctrl-C handling may be flaky.
3510 :     o Windows system calls and Windows I/O are not supported.
3511 :    
3512 :     A new set of binfiles is located at:
3513 :    
3514 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3515 :    
3516 :     This is only needed for bootstrapping the cygwin version of smlnj.

3558 :     This fixes the problem of CM getting confused by files that suddenly
3559 :     change their identity (e.g., by getting unlinked and recreated by some
3560 :     text editor such as vi). There might be a better/cheaper/cleaner way

3673 :     Another small change is that ppDec tries to give more information
3674 :     than just "<sig>" in the case of functors. However, this code is
3675 :     broken in some mysterious way if the functor's body's signature
3676 :     has not been declared by ascription but gets inferred from the
3677 :     implementation. This needs fixing...

3786 :    
3787 :     3. Modified init scripts because XXX_DEFAULT environment variables

3796 :     Description:
3797 :    
3798 :     All pseudo-ops emitted before the first segment declaration
3799 :     such as TEXT, DATA, and BSS directives are assumed to be global
3800 :     declarations and are emitted first in the assembly file. This is
3801 :     useful in a number of situations where one has pseudo-ops that are not
3802 :     specific to any segment, and also works around the constraint that one
3803 :     cannot have client pseudo-ops in the TEXT segment.
3804 :    
3805 :     Because no segment is associated with these declarations it is
3806 :     an error to allocate any space or objects before the first segment
3807 :     directive and an exception will be raised. However, we cannot make
3808 :     this check for client pseudo-ops.
3809 :    
3810 :     These top level declarations are a field in the CFG graph_info.
3811 :     In theory you can continue to add to this field after the CFG has been
3812 :     built -- provided you know what you are doing;-)

3835 :     Description:
3836 :    
3837 :     Applied the following bugfix provided by Emden Gansner:
3838 :    
3839 :     Output is corrupted when outputSubstr is used rather than output.
3840 :    
3841 : blume 2155 The problem occurs when a substring
3842 : blume 1189
3843 :     ss = (s, dataStart, dataLen)
3844 :    
3845 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3846 :     avail bytes of s, starting at index dataStart, are copied into the
3847 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3848 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3849 :     starting this copy at index dataStart+avail in s, the current code
3850 : blume 1189 starts the copy at index avail.
3851 :    
3852 :     Fix:
3853 :     In text-io-fn.sml, change line 695 from
3854 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3855 : blume 2155 to

3872 :     Description:
3873 :    
3874 :     Added full support for div/mod/rem/quot on the x86, using the machine
3875 :     instruction's two results (without clumsily recomputing the remainder)
3876 :     directly where appropriate.
3877 :    
3878 :     Some more extensive power-of-two support was added to the x86 instruction
3879 :     selector (avoiding expensive divs, mods, and muls where they can be
3880 :     replaced with cheaper shifts and masks). However, this sort of thing
3881 :     ought to be done earlier, e.g., within the CPS optimizer so that
3882 :     all architectures benefit from it.
3883 :    
3884 :     The compiler compiles to a fixed point, but changes might be somewhat
3885 :     fragile nevertheless. Please, report any strange things that you might
3886 :     see wrt. div/mod/quot/rem...

3896 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3897 :     The problem was with quotient = 0, because that alone does not tell

3908 :    
3909 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
3910 :    
3911 :     Primops have changed. This means that the bin/boot-file formats have
3912 :     changed as well.
3913 :    
3914 :     To make sure that there is no confusion, I made a new version.
3915 :    
3916 :    
3917 :     CHANGES:
3918 :    
3919 :     * removed REMT from mltree (remainder should never overflow).
3920 :    
3921 :     * added primops to deal with divisions of all flavors to the frontend
3922 :    
3923 :     * handled these primops all the way through so they map to their respective
3924 :     MLRISC support
3925 :    
3926 :     * used these primops in the implementation of Int, Int32, Word, Word32
3927 :    
3928 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3929 :    
3930 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
3931 :    
3932 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3933 :     floating point
3934 :    
3935 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3936 :     and Real (but Real.abs maps to a separate floating-point-only primop)
3937 :    
3938 :    
3939 :     TODO items:
3940 :    
3941 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
3942 :     instructions because the machine instruction encoder cannot handle
3943 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
3944 :     REM in the first place, and REM is supported by the x86 machine coder.)
3945 :    
3946 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
3947 :     selection phase. (The two can be streamlined because the hardware
3948 :     delivers both quotient and remainder at the same time anyway.)
3949 :    
3950 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
3951 :     (Currently the behavior is inconsistent both across architectures and
3952 :     wrt. the draft Basis spec.)
3953 :    
3954 :     * Word8 should eventually be handled natively, too.
3955 :    
3956 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
3957 :     as if there currently is no execution path that could trigger it in
3958 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
3959 :     hold for things like multiplication and division.)

3964 :     Tag: blume-20020327-mlrisc-divisions
3965 :     Description:
3966 :    
3967 :     Added support for all four division operations (ML's div, mod, quot,
3968 :     and rem) to MLRISC. In the course of doing so, I also rationalized
3969 :     the naming (no more annoying switch-around of DIV and QUOT), by
3970 :     parameterizing the operation by div_rounding_mode (which can be either
3971 :     DIV_TO_ZERO or DIV_TO_NEGINF).
3972 :    
3973 :     The generic MLTreeGen functor takes care of compiling all four
3974 :     operations down to only round-to-zero div.
3975 :    
3976 :     Missing pieces:
3977 :    
3978 :     * Doing something smarter than relying on MLTreeGen on architectures
3979 :     like, e.g., the x86 where hardware division delivers both quotient and
3980 :     remainder at the same time. With this, the implementation of the
3981 :     round-to-neginf operations could be further streamlined.
3982 :    
3983 :     * Remove inlining support for div/mod/rem from the frontend and replace it
3984 :     with primops that get carried through to the backend. Do this for all
3985 :     int and word types.

3990 :     Tag: blume-20020325-divmod
3991 :     Description:
3992 :    
3993 :     I improved (hopefully without breaking them) the implementation of Int.div,
3994 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
3995 :     advantage of the following observations:
3996 :    
3997 :     Let q = x quot y r = x rem y
3998 :     d = x div y m = x mod y
3999 :    
4000 :     where "quot" is the round-to-zero version of integer division that
4001 :     hardware usually provides. Then we have:
4002 :    
4003 :     r = x - q * y where neither the * nor the - will overflow
4004 :     d = if q >= 0 orelse x = q * y then q else q - 1
4005 :     where neither the * nor the - will overflow
4006 :     m = if q >= 0 orelse r = 0 then r else r + y
4007 :     where the + will not overflow
4008 :    
4009 :     This results in substantial simplification of the generated code.
4010 :     The following table shows the number of CFG nodes and edges generated
4011 :     for
4012 :     fun f (x, y) = x OPER y
4013 :     (* with OPER \in div, mod, quot, rem *)

4068 :     (* Allocate uninitialized storage on the heap.
4069 :     * The record is meant to hold short-lived C objects, i.e., they
4070 : blume 2155 * are not ML pointers. With the tag, the representation is

4091 :     a. The first is whether the C call is reentrant, i.e., whether

4095 :    
4096 :     These things are currently not handled in the code generator, yet.
4097 :    
4098 :     4. In CProto,
4099 :    
4100 : blume 2155 An encoding type of "bool" means "ml object" and is mapped into
4101 :     C prototype of PTR. Note that "bool" is different than "string",
4102 : leunga 1174 even though "string" is also mapped into PTR, because "bool"
4103 :     is assigned an CPS type of BOGt, while "string" is assigned INT32t.
4104 :    
4105 :     5. Pickler/unpicker
4106 :    
4107 :     Changed to handle RAW_RECORD and newest RAW_CCALL
4108 :    
4109 :     6. MLRiscGen,
4110 :    
4111 :     1. Changed to handle the new rawload/rawstore/rawrecord operators.
4112 :     2. Code for handling C Calls has been moved to a new module CPSCCalls,
4113 :     in the file CodeGen/cpscompile/cps-c-calls.sml
4114 :    
4115 :     7. Added the conditional move operator
4116 :    
4117 :     condmove of branch
4118 :    
4119 : blume 2155 to cps. Generation of this is still buggy so it is currently
4120 : leunga 1174 disabled.

4126 : george 1168 Description:
4127 :    
4128 : blume 2155 Implemented the Ball-Larus branch prediction-heuristics, and
4129 : george 1168 incorporated graphical viewers for control flow graphs.
4130 :    
4131 : george 1171 Ball-Larus Heuristics:
4132 : george 1168 ---------------------
4133 :     See the file compiler/CodeGen/cpscompile/cpsBranchProb.sml.
4134 :    
4135 :     By design it uses the Dempster-Shafer theory for combining
4136 :     probabilities. For example, in the function:
4137 :    
4138 :     fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)
4139 :    
4140 :     the ball-larus heuristics predicts that the n=0 is unlikely
4141 :     (OH-heuristic), and the 'then' branch is unlikely because of the
4142 :     RH-heuristic -- giving the 'then' branch an even lower combined
4143 : george 1171 probability using the Dempster-Shafer theory.
4144 : george 1168
4145 :     Finally, John Reppy's loop analysis in MLRISC, further lowers the
4146 :     probability of the 'then' branch because of the loop in the else
4147 :     branch.
4148 :    
4149 :    
4150 :     Graphical Viewing:
4151 : blume 2155 ------------------
4152 : george 1168 I merely plugged in Allen's graphical viewers into the compiler. The
4153 :     additional code is not much. At the top level, saying:
4154 :    
4155 :     Control.MLRISC.getFlag "cfg-graphical-view" := true;
4156 :    
4157 :     will display the graphical view of the control flow graph just before
4158 :     back-patching. daVinci must be in your path for this to work. If
4159 :     daVinci is not available, then the default viewer can be changed
4160 :     using:
4161 :    
4162 :     Control.MLRISC.getString "viewer"
4163 :    
4164 :     which can be set to "dot" or "vcg" for the corresponding viewers. Of
4165 :     course, these viewers must be in your path.
4166 :    
4167 :     The above will display the compilation unit at the level of clusters,
4168 :     many of which are small, boring, and un-interesting. Also setting:
4169 :    
4170 :     Control.MLRISC.getInt "cfg-graphical-view_size"
4171 :    
4172 :     will display clusters that are larger than the value set by the above.
