235 :     Description:
236 :    
237 :     - Aaron: fixed a number of bugs in ml-ulex.
238 :     - Matthias:
239 :     - added CM control "cm.force-tools"; this is false by default;
240 :     when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
241 :     will be forced to run regardless of whether or not their targets
242 :     are up-to-date
243 :     - changed installer code so that config/install.sh will re-build
244 :     heap images for all tools even if those heap images already existed
245 :    
246 :     ----------------------------------------------------------------------
247 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
248 : blume 2688 Date: 2007/06/04 21:21:00 CDT
249 :     Description:
250 :    
251 :     After Aaron Turon's bug fix for ml-ulex (handling the ^ character
252 :     in legacy mode), re-ran the lexer generator on all lex input files
253 :     and committed the results.
254 :    
255 :     This should fix the problem with ckit and nlffi that was reported
256 :     by Vesa A. Norrman.

267 : dbm 2650 Name: Dave MacQueen (dbm@cs.uchicago.edu)
268 :     Date: 2007/05/31 14:55:00 CDT
269 :     Revision: 2650
270 :     Description:
271 :    
272 :     3rd merge of base from primop-branch-3 into the trunk.
273 :     Additional bug fixes included:
274 :    
275 :     * Timer.cpu_timer, etc. type printing corrected (by making
276 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
277 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
278 :     Stefan Monnier)
279 :    
280 :     ----------------------------------------------------------------------
281 : blume 2645 Name: Matthias Blume (http://www.tti-c.org/blume/)
282 :     Date: 2007/05/31 11:40:00 CDT
283 :     Description:
284 :    
285 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
286 :    
287 :     Also, changed the handling of "no core access": When translate.sml
288 :     needs access to a core exception at a time when the core has not
289 :     been set up yet (this only happens when compiling system/smlnj/init/*),
290 :     then don't bother generating the corresponding tests.
291 :    
292 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
293 :     the exception. Unfortunately, that confuses the plambda type checker.
294 :     Moreover, it does not do any good, because at runtime we don't expect
295 :     such an exception to be ever raised. (The code in system/smlnj/init/*
296 :     has to be written very carefully with this in mind!)

299 : mrainey 2639 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
300 :     Date: 2007/05/29
301 :     Description:
302 :    
303 :     Added FSQRT instructions for the AMD64 code generator.
304 :    
305 :     ----------------------------------------------------------------------
306 : blume 2626 Name: Matthias Blume (http://www.tti-c.org/blume/)
307 :     Date: 2007/05/29 19:00:00 CDT
308 :     Description:
309 :    
310 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
311 :     with an explicit test for zero division. This should fixes several
312 :     regressions and makes it possible for downstream optimization phases
313 :     to treat these operations as "pure" when they are applied to unsigned
314 :     operands.
315 :    
316 :     ----------------------------------------------------------------------
317 : mrainey 2622 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
318 :     Date: 2007/05/29
319 :     Description:
320 :    
321 :     Added the new MLRISC code generator for the AMD64. This version,
322 :     in contrast to the previous one, uses SSE registers and instructions
323 :     for all floating-point computations.
324 :

326 : jhr 2613 Name: John Reppy (http://www.cs.uchicago.edu/~jhr)
327 : jhr 2617 Date: 2007/05/29
328 : jhr 2613 Description:
329 :    
330 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
331 :     for bugs #1415 and #1416. We also now correctly handle format characters that
332 :     lie outside the specified set.

335 : blume 2610 Name: Matthias Blume (http://www.tti-c.org/blume/)
336 :     Date: 2007/05/23 22:30:00 CDT
337 :     Description:
338 :    
339 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
340 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
341 :    
342 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
343 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
344 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
345 :     while running CMB.make. The point is that the single symbol
346 :     NO_PLUGINS is definde in all three cases.)
347 :    
348 :     I changed the three locations within the sources that get compiled
349 :     during CMB.make where ml-yacc or ml-lex input is processed: When
350 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
351 :     is bypassed.
352 :    
353 :     When bootstrapping new versions of the compiler, there can be
354 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
355 :     are not available or otherwise not operational. In this case one can
356 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
357 :     do so, the following command should be issued at the interactive
358 :     prompt:
359 :    
360 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
361 :    
362 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
363 :     files that normally would be generated by ml-yacc and ml-lex.
364 :     (Copies of these files are in the repository.)
365 :    
366 :     ----------------------------------------------------------------------
367 : dbm 2603 Name: David MacQueen (dbm@cs.uchicago.edu)
368 :     Date: 2007/5/23 17:23:00 CDT
369 :     Revision: 2603
370 :     Description:
371 :    
372 :     2nd merge of base from primop-branch-3 into the trunk.
373 :     Additional bug fixes included:
374 :     Date.scan and Date.fromString fixed;
375 :     Overloading resolution fixed and some type printing problems corrected.

378 : blume 2578 Name: Matthias Blume (http://www.tti-c.org/blume/)
379 : blume 2589 Date: 2007/05/23 09:50:00 CDT
380 :     Description:
381 :    
382 :     Changed the installation mechanism for CM tool plugins. These are
383 :     just libaries and now get installed like ordinary libaries.
384 :    
385 :     There are now a number of new installation targets that give some
386 :     fine-grain control over what classes and suffixes are known, and what
387 :     they will map to.
388 :     See config/targets for details.
389 :    
390 :     The code that caused plugin installation as part of running a
391 :     tool's "build" script has been removed. (The build script is for
392 :     building, not for installing.)
393 :    
394 :     ----------------------------------------------------------------------
395 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
396 : blume 2578 Date: 2007/05/22 11:50:00 CDT
397 :     Description:
398 :    
399 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
400 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
401 :     CM fail if a shell tool reports a non-success exit status. If
402 :     the control is set to true, then CM will press on after tool failures
403 :     in the event that the target files exist (even though they are
404 :     considered outdated). Turning the control to true can be useful for
405 :     bootstrapping.

408 : adrassi 2570 Name: Aaron Turon (http://www.cs.uchicago.edu/~adrassi)
409 :     Date: 2007/05/19
410 :     Description:
411 :    
412 :     Merge of ml-lpt revisions for 110.64.
413 :    
414 :     The name of several ml-lpt-lib modules has changed:
415 :     Repair => AntlrRepair
416 :     StreamPos => AntlrStreamPos
417 :     ErrHandlerFn => AntlrErrHandler
418 :     EBNF => AntlrEBNF
419 :    
420 :     The ml-antlr specification format has changed: declarations such as
421 :     %tokens and nonterminal definitions can occur *multiple* times in the
422 :     same specification. The semantics are such that each new declaration
423 :     extends the previous ones. This does not apply to %start or %name,
424 :     of course.
425 :    
426 :     Importing a grammar via %import now includes *all* declarations in from
427 :     the imported grammar, except for %name, %entry, and %start. Tokens
428 :     and nonterminals can be dropped using the new %dropping clause of the
429 :     %import directive; the separate %drop and %extend have been removed.
430 :    
431 :     We now allow optional type annotations on nonterminals, using the %nonterms
432 :     directive as in ml-yacc.
433 :    
434 :     The refcell construct is now implemented using SML's regular reference
435 :     cells, so the :== and !! notation has been deprecated.
436 :    
437 :     The ml-antlr tool now does much more checking of specifications, and
438 :     its error messages have been greatly improved. Error repair for
439 :     generated parsers has been completely rewritten, and is now both
440 :     much faster and more accurate.
441 :    
442 :     ml-ulex is now more lenient with escape codes (non-SML-standard
443 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
444 :     Also, character classes may now include a "-" character at the beginning
445 :     as is standard in most other regexp tools.
446 :    
447 :     All of these changes are documented in the user guide, which has
448 :     been updated and improved with this merge.

456 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
457 :     Significant changes in FLINT and the front end, mostly having to do

465 :    
466 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
467 :     The ml-antlr specification format has changed: declarations such as
468 :     %tokens and nonterminal definitions can occur *multiple* times in the
469 :     same specification. The semantics are such that each new declaration
470 :     extends the previous ones. Grammar extension constructs have also
471 :     changed. We now allow type annotations on nonterminals. Finally,
472 :     the refcell construct is now implemented using SML's regular reference
473 :     cells, so the :== and !! notation has been deprecated. All of these
474 :     changes will appear in the 110.64 user guide for ml-lpt.
475 :    
476 :     The ml-antlr tool now does much more checking of specifications, and
477 :     its error messages have been greatly improved. There has also been
478 :     some work on the error repair process for generated parsers, but this
479 :     will be further improved in 110.64.

599 :     Description:
600 :    
601 :     Added preliminary support in MLRISC for Staged Allocation, a technique
602 :     for specifying calling conventions (see
603 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
604 :     Initially, we plan to use this code to generate C calls for the AMD64.
605 :    
606 :     The staged allocation code base resides in MLRISC/staged-allocation,
607 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

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

671 :     Date: 2007/01/31
672 :     Description:
673 :    
674 :     Brought ml-lpt manual up-to-date with the code. Many minor
675 :     improvements to the tools, and a few minor bugfixes. Prepared
676 :     ml-lpt-lib for integration with new UTF8 structure. Changed
677 :     the interface for creating streams in ml-ulex (we now support
678 :     stream creation from several kinds of sources). Overall, the
679 :     tools are now quite stable, and their interfaces are unlikely to
680 :     change in a way that would break compatibility. More work,
681 :     however, is needed in the documentation.

685 : blume 2298 Date: 2007/02/01 10:05:00 CST
686 :     Description:
687 :    
688 :     Implemented library installer. Moved CM plugin code for
689 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
690 :     their respective trees. Implemented CM plugin for ml-ulex
691 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
692 :     and ml-antlr.
693 :    
694 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
695 :     CM tools. (It turns out to be too messy to do otherwise because
696 :     there is too much code that during installation relies on the presence
697 :     of these tools -- resulting in a tricky ordering problem.)

701 : blume 2277 Date: 2007/01/30 11:05:00 CST
702 :     Description:
703 :    
704 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
705 :     Modified CM's startup code to use shiftArgs as it processes
706 :     command line arguments. This way, the init code in each .sml-file
707 :     or library that is mentioned at the top level will see only
708 :     those arguments that have not yet been processed at this point.
709 :     In other words, the init code can "seize control" and process the
710 :     remaining command line.

725 :     Added the UTF8 structure and signature from the Moby compiler to
726 :     the SML/NJ library (and the CML library). These modules will replace
727 :     the version in the ml-lpt-lib.

776 :     Date: 2006/12/08 09:50:00 CST
777 :     Description:
778 :    
779 :     Added code to CM's "standard shell tool" implementation which
780 :     causes it to tolerate (with a warning) the situation where the shell
781 :     command fails (e.g., due to the shell command's non-existence)
782 :     as long as all target files exist.
783 :    
784 :     This makes it possible to, e.g., build ml-yacc from sources even if
785 :     svn checkout messed up the time stamps on files in such a way that
786 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
787 :     be needed to re-process yacc.grm, but obviously it might not yet be
788 :     available at that time.)

797 :     in the SML Basis specification too.

868 :     ml-lpt
869 :    
870 :     directory containing two new program generator tools: ml-ulex and
871 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
872 :     LL(k) parser generator). These tools are currently "beta-quality"
873 :    
874 :     The latest versios of the sources can now be obtained anonymously
875 :     via subversion. For this, it is useful to first check out
876 :    
877 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
878 :    
879 :     and put the resulting directory on your shell's PATH. This provides
880 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
881 :     and refresh-all.sh.
882 :    
883 :     To create a freshly checked-out copy of the sources, do
884 :    
885 :     checkout-all.sh [dir]
886 :    
887 :     where dir is the optional SML/NJ root directory (default is ".").
888 :    
889 :     This creates the above directory layout. Each subdirectory of
890 :     the root is under individual subversion control. The stat-all.sh
891 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
892 :     each of these subtrees.

896 : blume 2155 Date: 2006/11/02 12:20:00 CST
897 :     Description:
898 :    
899 :     Reorganized directory layout.
900 :    
901 :     This is a temporary solution, more reorganization is to come.
902 :    
903 :     The basic idea is to have a number of toplevel trees, each corresponding
904 :     to a well-defined part of the overall system. Each part can be
905 :     maintained individually, even in separate source repositories,
906 :     although currently we still serve everything out of the main
907 :     smlnj-gforge tree.
908 :    
909 :     Installer and and scripts have been updated to reflect the new
910 :     layout. The installer (base/src/system/smlnj/installer) is now
911 :     "scriptable" to avoid burning too much knowledge about the
912 :     layout into SML source code. The main script used by the installer
913 :     is in config/actions.
914 :    
915 :     The main change is that many of the subdirectories of what used to
916 :     be known as "src" have moved to the toplevel. The "src" directory
917 :     itself has moved down into a subtree called "base". (We may eventually
918 :     get rid of the extra level of indirection represented by "src".)
919 :    
920 :     The layout is now as follows:
921 :    
922 :     toplevel tree name | default repository
923 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
924 :     -------------------+----------------------------------------------------
925 :     config | $gf/config/trunk
926 :     |
927 :     base | $gf/sml/trunk
928 :     |
929 :     smlnj-lib | $gf/smlnj-lib/trunk
930 :     MLRISC | $gf/MLRISC/trunk
931 :     |
932 :     ml-yacc | $gf/ml-yacc/trunk
933 :     ml-lex | $gf/ml-lex/trunk
934 :     ml-burg | $gf/ml-burg/trunk
935 :     lexgen | $gf/lexgen/trunk
936 :     heap2asm | $gf/heap2asm/trunk
937 :     |
938 :     cml | $gf/cml/trunk
939 :     eXene | $gf/eXene/trunk
940 :     ckit | $gf/ckit/trunk
941 :     nlffi | $gf/nlffi/trunk
942 :     |
943 :     smlnj-c | $gf/smlnj-c/trunk
944 :    
945 :     In $gf/admin there are a few useful shell scripts for checking out
946 :     and maintaining the entire collection of trees:
947 :    
948 :     admin/checkout-all.sh [dir]
949 :     -- optionally creates dir and checks out all trees from their
950 :     default repositories; if dir is missing, checkout into .
951 :     admin/refresh-all.sh [dir]
952 :     -- looks at all trees (from the above list) in dir (default: .)
953 :     and runs "svn update" if the tree exists and is under
954 :     subversion control;
955 :     non-existing or non-subversion trees are skipped
956 :     admin/stat-all.sh [dir]
957 :     -- like refresh-all.sh, but runs "svn stat" instead

1142 : mblume 1878 be referred to by another name. In 110.57 this would be

1200 :     Description:
1201 :    
1202 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1203 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1204 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1205 :     it. Instead, it has the status of "user code", so it should use
1206 :     $/basis.cm to refer to the Basis library. (At least that's true for
1207 :     the purpose of bootstrapping the previous change. In the future it
1208 :     might make sense to have versiontool.cm refer to
1209 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1210 :     compiler itself uses.)

1218 :     Tag: blume-22051115-libraries
1219 :     Description:
1220 :    
1221 :     This change affects the way the following libraries are tied into
1222 :     the system:
1223 :    
1224 :     $/basis.cm
1225 :     $/smlnj-lib.cm
1226 :     $/pp-lib.cm
1227 :     $/controls-lib.cm
1228 :     $/html-lib.cm
1229 :     $/ml-yacc-lib.cm
1230 :    
1231 :     These libraries are now internally (as seen from the source code
1232 :     of the implementation itself) known by the following names:
1233 :    
1234 :     $smlnj/basis/basis.cm
1235 :     $smlnj/smlnj-lib/smlnj-lib.cm
1236 :     $smlnj/smlnj-lib/pp-lib.cm
1237 :     $smlnj/smlnj-lib/controls-lib.cm
1238 :     $smlnj/smlnj-lib/html-lib.cm
1239 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1240 :    
1241 :     This makes it possible to work with code that requires different
1242 :     versions of these libraries, and which refers to these libraries using
1243 :     their "default" names (i.e., the first set of names above). In other
1244 :     words, one can un-define or re-define those default names without
1245 :     compromising the proper functioning of the compiler itself.
1246 :    
1247 :     A similar procedure had already been performed for several of the
1248 :     MLRISC libraries that are linked into the compiler. I did some
1249 :     cleanup on this code.
1250 :    
1251 :     A new file in the config directory (named extrapathconfig) is
1252 :     responsible for setting up path anchors that the compiler itself does
1253 :     not need, but that are typically required by user code.

1432 :     Tag: blume-20050516-redump-heap
1433 :     Description:
1434 :    
1435 :     Added mechanism for re-creating a heap file for the interactive system
1436 :     after configuration variables have been changed.
1437 :    
1438 :     CM.redump_heap : string -> unit
1439 :    
1440 :     This is much like SMLofNJ.exportML, but starting from the resulting
1441 : blume 2155 heap does not return to the caller of CM.redump_heap but
1442 : mblume 1792 restarts the interactive system from scratch. The original call of
1443 :     CM.redump_heap does not return but ends the interactive session.
1444 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1445 :    
1446 :     Internally, redump_heap winds the dynamic execution context back to
1447 :     the point where the original heap image was created and re-executes
1448 :     the heap image generation code in the boot code.

1458 :     as specified with respect to the interaction of radix and prefix.

1508 :     Description:
1509 :    
1510 :     Brought back SMLofNJ.Susp. The underlying suspension type is the one
1511 :     implemented in Core -- which means that it is the same as the one used

1538 :     Implemented "long long" arguments and results for NLFFI. (Only the
1539 :     PPC/MacOS implementation is complete, the other backends still need to
1540 :     be updated.)

1564 :     Tag: blume-20050114-heap2exec
1565 :     Description:
1566 :    
1567 :     Implemented new (but still experimental) heap2exec facility. This is
1568 :     tested under Mac OS X and should work under Linux (will test shortly).
1569 :     It will probably also work on the Sparc (will test some time later).
1570 :    
1571 :     - removed old "HACKED_STANDALONE" hack from runtime
1572 :    
1573 :     To be able to test this, uncomment the request for "heap2asm" in
1574 :     config/targets prior to installation. (Notice that this is different
1575 :     from "heap2exec" mentioned below. Not a typo.)
1576 :    
1577 :     To perform an actual test, run the command
1578 :    
1579 :     $ bin/heap2exec heapfile execfile
1580 :    
1581 :     (You can put heap2exec on your shell's path.)
1582 :    
1583 :     For example, run
1584 :    
1585 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1586 :    
1587 :     This will create a standalone executable called "mly" which you can
1588 :     then invoke directly as a command.

1614 :     data structure access seems to work.)
1615 :    
1616 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1617 :     (On the Mac, it is big-endian. And that's currently our only
1618 :     PPC platform.)

1635 :    
1636 : blume 2155 The Unix I/O library of SML/NJ on cygwin does not understand
1637 :     Windows style pathname, so problems arise when SMLNJ_HOME is set

1684 :     Description:
1685 :    
1686 :     Hacked some of the scripts (in particular: the installer) to cope with
1687 :     spaces in filenames a bit better. But beware: the current "solution"
1688 :     is likely still full of bugs and inherently incomplete. (We need to
1689 :     do away with those shell scripts for a comprehensive solution.)

1733 :     Tag: blume-20041124-position
1734 :     Description:
1735 :    
1736 :     The compiler can now be compiled in a mode that makes structure Position
1737 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1738 :     for the time being.
1739 :    
1740 :     To enable 64-bit positions, use the following procedure:
1741 :    
1742 :     1. Start sml
1743 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1744 :     3. Type
1745 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1746 :     4. Run CMB.make() as usual.
1747 :    
1748 :     This is barely tested. The only test so far was a little SML program
1749 :     counting the number of characters in an 8-gigabyte file by
1750 :     reading it character-by-character. That test was successful.
1751 :    
1752 :     In support of 64-bit positions, a number of new functions have been
1753 :     added to the runtime system.

1798 :    
1799 :     - In a previous commit, fixed a minor issue with how polyequal is being
1800 :     translated. In particular, the code now "looks through" abstractions.
1801 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1802 :     more efficient code. Important examples for where this matters are
1803 :     the new int64 and word64 types.

1819 :    
1820 :     All the pieces of Word64 are now there, with the exception of the
1821 :     conversions from and to LargeWord. (Eventually these need to be identities,
1822 :     but for the time being they don't even make sense because LargeWord is
1823 :     32-bit wide.)
1824 :    
1825 :     Also started to add similar support for Int64, but major pieces of that
1826 :     are still missing.

1831 :     Tag: blume-20041111-word64
1832 :     Description:
1833 :    
1834 :     Structure Word64 is now (almost) complete, word literals and patterns
1835 :     seem to work. There are a few odd pieces missing. In particular,
1836 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1837 :     at the moment.
1838 :    
1839 :     Making Word64 official would mean that LargeWord becomes Word64. But
1840 :     this requires extreme care because most word-word conversions have to
1841 :     go through LargeWord, so making a mistake means loss of efficiency or
1842 :     worse. Eventually there will be a solution similar to (but actually
1843 :     simpler than) what I did with IntInf.

1878 :     - Made corresponding changes to config/install.sh and config/unpack.
1879 :     - Default contents of config/srcarchiveurl uses $VERSION and
1880 :     normally does not have to be edited to reflect a version change.
1881 :    
1882 :     (As a result, a version change can be done by just editing
1883 :     config/version, the rest is now automatic.)

1923 :     Tag: blume-20041020-standalone-backtrace
1924 :     Description:
1925 :    
1926 :     Added a mechanism for getting back-trace information from standalone
1927 :     programs. Here is how it works:
1928 :    
1929 :     1. The part of the program from which you want to get backtrace
1930 :     information (usually the whole program) should be wrapped with
1931 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
1932 :     main program could be modified from something like
1933 :    
1934 :     fun main (pgm, args) = ...
1935 :    
1936 :     to
1937 :    
1938 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1939 :    
1940 :     2. To be able to access BackTrace.monitor, you have to add
1941 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
1942 :     main function.
1943 :    
1944 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1945 :     CM might have created in the past for your project).
1946 :    
1947 :     4. Build the system using this command line:
1948 :    
1949 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1950 :     myprog.cm MyProg.main myprog
1951 :    
1952 :     instead of the usual
1953 :    
1954 :     ml-build myprog.cm MyProg.main myprog
1955 :    
1956 :     I changed a library name:
1957 :    
1958 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1959 :    
1960 :     New libraries:
1961 :    
1962 :     $smlnj-tdp/back-trace.cm
1963 :     -- when loaded causes the back-trace plugin to be installed
1964 :     $smlnj-tdp/coverage.cm
1965 :     -- when loaded causes the coverage plugin to be installed

1981 :     Description:
1982 :    
1983 :     * Test coverage tool added!
1984 :     * Further reorganization of tracing-, debugging-, and profiling support:
1985 :    
1986 :     - moved original BTImp -- now called BackTrace -- into a separate
1987 :     library called $/trace-debug-profile.cm
1988 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
1989 :     - only the instrumentation mechanism is now left in the compiler proper
1990 :     - BackTrace module is a plugin which is NOT plugged in by default
1991 :     - Coverage module is another such plugin
1992 :    
1993 :     To get the benefits of any of these plugin modules, the code in
1994 :     question must be compiled with tdp instrumentation turned on. This
1995 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
1996 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1997 :    
1998 :     Plugins are selected at link time. (Pre-compiled instrumented code
1999 :     can be re-loaded with different plugins in effect.) When an
2000 :     instrumented module is linked, whatever plugins are at that time
2001 :     enabled will come into effect for that module.
2002 :    
2003 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2004 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2005 :     To enable the coverage plugin, load the same library and invoke
2006 :     Coverage.install().
2007 :    
2008 :     Back-traces are generated automatically on uncaught exceptions and
2009 :     when the code in question explicitly invokes BackTrace.trigger().
2010 :    
2011 :     Coverage (and execution frequency-) information must be queried
2012 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2089 :     Description:
2090 :    
2091 :     Cleaned up the absyn to reflect the invariant that HANDLE always
2092 :     carries a FNexp as part of the type definition. This eliminates some
2093 :     superfluous sanity checks at runtime down the road.
2094 :    
2095 :     Some minor cleanup of the btrace code.

2101 :     Description:
2102 :    
2103 :     Added hack to make slave mode work in the presence of the version
2104 :     tool. (Still, since the master does two passes over the code for
2105 :     CMB.make, the release number gets bumped twice when slaves are
2106 :     attached. I don't know if this is worth fixing...)

2112 :     Description:
2113 :    
2114 :     * Moved the "version" magic into its own little library under
2115 : mblume 1672 src/system/smlnj/internal. This avoids expensive reconstruction of
2116 :     a stable src/compiler/core.cm.
2117 : mblume 1639
2118 : mblume 1672 * At the same time, structure CompilerVersion is now known as
2119 :     structure SMLNJVersion.
2120 : mblume 1639
2121 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2122 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2123 :     Also, loading the versiontool does not work when rebuilding the system
2124 :     because CM is not properly initialized at that time.

2129 :     Tag: blume-20040929-autoversion
2130 :     Description:
2131 :    
2132 :     Implemented some CM magic to have
2133 :     file src/compiler/TopLevel/main/version.sml
2134 :     generated automagically.
2135 :     The version is taken from two files: config/version and config/release.
2136 :     The first is expected to contain a two-part version number such as 110.49.
2137 :     The second should contain a single number, but it may be missing.
2138 :    
2139 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2140 :     time the version tool is loaded (which is the first time you say CMB.make),
2141 :     then the tool will increment the value stored in config/release every
2142 :     time CMB.make is invoked.
2143 :    
2144 :     The binfile format is now insensitive to anything beyond the first
2145 :     two components of a version number, so bumping the release does not render
2146 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2147 :     during development without invalidating existing binfiles.
2148 :    
2149 :     In any case, every CMB.make updates the date information in version.sml.
2150 :     (This is the date that is printed in the banner.)

2162 : mblume 1633 Date: 2004/09/27 22:08:00 CDT
2163 :     Tag: blume-20040927-controls
2164 :     Description:
2165 :    
2166 :     Added two pieces of functionality to the Controls interface:
2167 :    
2168 :     1. val save'restore: 'a control -> unit -> unit
2169 :    
2170 :     grabs the current value of the control in stage 1 and restores it
2171 :     in stage 2.
2172 :    
2173 :     2. val set' : 'a control * 'a -> unit -> unit
2174 :    
2175 :     stores the given value into the control in stage 2 (i.e., delayed)
2176 :     but does all error checking in stage 1.
2177 :     (This is for string controls that need to do parse their argument --
2178 :     something that might fail. In some cases, notably in CM, one
2179 :     already knows the intended argument but wants to delay the actual
2180 :     assignment until a time when error recovery would be more difficult.)
2181 :    
2182 :     Changed the handling of controls in tool arguments to classes "sml" and
2183 :     "lazysml":
2184 :     - use Controls.save'restore as a more robust way of restoring the
2185 :     old value (in particular: without having to re-parse the string)
2186 :     - use controls to handle the "overload" keyword in the init group
2187 :     (I believe this change actually fixes a long-standing obscure bug.)

2192 :     Tag: blume-20040927-lazysml
2193 :     Description:
2194 :    
2195 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2196 :     difference to "sml" is that compilation is done with Control.lazysml
2197 :     set to true. A source of class "lazysml" is automatically recognized
2198 :     by a file name suffix of ".lml".
2199 :    
2200 :     In addition to the above feature, the original class "sml" now also
2201 :     supports a tool argument "lazy" which has the same effect. As a
2202 :     result, the following three lines are equivalent:
2203 :    
2204 :     foo.sml : lazysml
2205 :     foo.sml : sml (lazy)
2206 :     foo.sml (lazy)
2207 :    
2208 :     The setting goes into effect both during parsing and during
2209 :     compilation. The original setting is restored right after parsing and
2210 :     after compilation, respectively.
2211 :    
2212 :     In addition to all the above, there is also a general mechanism to set
2213 :     ANY of the "controls" that are available at the command line via
2214 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2215 :     apply as well. (In fact, "lazy" is implemented as a special case of
2216 :     the general mechanism.)
2217 :    
2218 :     The .cm file syntax uses a new keyword tool argument called "with".
2219 :     There are several ways of indicating the desired settings:
2220 :    
2221 :     foo.sml (with:parser.quotations=true)
2222 :     foo.sml (with:(name:parser.quotations value:true))
2223 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2224 :     foo.sml (with:(name1=value1 name2=value2 ...))
2225 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2226 :    
2227 :     etc.
2228 :    
2229 :     Another possible abbreviation is to leave out the =v or value:v part
2230 :     if the name refers to a boolean control (in which case the value is
2231 :     taken to be true). Thus, one could get lazy sml also by saying:
2232 :    
2233 :     foo.sml (with:parser.lazy-keyword=true)
2234 :     foo.sml (with:parser.lazy-keyword)
2235 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2236 :     foo.sml (with:(name:parser.lazy-keyword))

2483 :    
2484 :     - Fixed minor issue in ml-nlffigen: Now generate structure T_foo
2485 :     for a typedef to an incomplete type, but leave out the "typ" member.
2486 :     (This is just for consistency.)
2487 :     - Started to produce what is supposed to become better (i.e., comprehensive)
2488 :     documentation of what ml-nlffigen does and produces.

2497 :     (ml-nlffigen, cproto.sml) that conveys C function interface
2498 :     information to the code generator.
2499 :    
2500 :     However, the actual architecture-specific implementation of function
2501 :     arguments and results that are C unions is still not implemented.

2534 :    
2535 :     - use paramAlloc to report c-calls with too many arguments
2536 :     (for PPC version where parameter area is pre-allocated)
2537 :     - added ccall_maxargspace to machspec (to implement the above)
2538 :     - made "make" commend in CM's "make" tool configurable
2539 :     - added option (default: on) for passing the name of the SML/NJ's "bin"
2540 :     directory to "make"; the call looks like this:
2541 :    
2542 :     make <options> SMLNJ_BINDIR=<dir> <target>
2543 :    
2544 :     This can be used by the Makefile to, e.g., pick the "right" version

2555 :     though.
2556 :    
2557 :     Note: 1. You have to make a new, clean build of the runtime system.

2560 :     If you absolutely have to do it, build the system under

2587 :     Tag: blume-20040617-timer-unix
2588 :     Description:
2589 :    
2590 :     Changed the interface of structures Timer and Unix to match the most
2591 :     recent Basis spec.
2592 :    
2593 :     In the case of Unix there still seems to be an open/weird issue:
2594 :    
2595 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2596 :     fresh streams whenever they are called -- as opposed to have them
2597 :     return the same stream every time. This design is supposed to
2598 :     prevent space leaks caused by proc values hanging on to streams.
2599 :    
2600 :     The reap function, on the other hand, is supposed to close the
2601 :     streams. This cannot be done without having a handle on the
2602 :     stream in proc after all...
2603 :    
2604 :     I took the liberty to implement the following stopgap solution:
2605 :    
2606 :     The proc value hangs on to the most recently created stream(s).
2607 :     Reap closes those. If either or both of the two streams hadn't
2608 :     been created at all yet, then reap will close the corresponding
2609 :     file descriptors directly.
2610 :    
2611 :     PS: I don't understand the original space leak argument anymore. If
2612 :     a proc hangs on to the imperative stream, then I/O operations on those
2613 :     will advance the state of the cached stream and avoid the space leak.

2626 :     Tag: blume-20040525-group-owner
2627 :     Description:
2628 :    
2629 :     CM now ignores (but still accepts) the "owner" information in group
2630 :     descriptions. The owner of a group is its next enclosing
2631 :     library. Each group must have a unique owner. (There is a virtual
2632 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2633 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2634 :     and CM would check that such a declaration is correct. The new scheme
2635 :     is to have CM check that for each group there is precisely one owning
2636 :     library.
2637 :    
2638 :     The advantage of the new scheme is that the programmer no longer needs
2639 :     to maintain the somewhat annoying owner information. The downside is
2640 :     that CM cannot enforce the ownership rule across multiple runs of
2641 :     CM.make. Fortunately, enclosing the same group in two different
2642 :     libraries A and B which are not part of the same program does not
2643 :     cause real problems.

2653 :     compiled correctly.)
2654 :    
2655 :     Also, included a minor addition to ml-build.bat analogous to what was
2656 :     done in blume-20040519-ml-build.

2662 :     Description:
2663 :    
2664 :     Arranged for ml-build to clean up after itself a little bit better.
2665 :     The script generates a temporary SML source file and compiles it using
2666 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
2667 :     gets rid of those at the end, so they don't accumulate under .cm.
2668 :    
2669 :     This required a minor change to install.sh because the name of the
2670 :     metadata directory (default: .cm) is actually configurable at
2671 :     installation time.

2689 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
2690 :     for the voluminous patch!
2691 :    
2692 :     (I have not tested this patch under win32 yet.)
2693 :    
2694 : mblume 1490 Here is David's e-mail:
2695 :    
2696 :     Hi,
2697 :    
2698 :     Attached to this email you find a diff against sml/nj 110.45
2699 :     that will enable socket support under Windows.
2700 :    
2701 :     To apply the patch (using unix or cygwin)
2702 :     1) gunzip runtime.diff.gz
2703 :     2) "cd" into "src/runtime" in the source tree of a fresh
2704 :     110.45 installation.
2705 :     3) patch -p 1 < [your/path/to]runtime.diff
2706 :    
2707 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2708 :     I only ran a few tests for basic socket client functionality
2709 :     (which worked fine). Especially the functions that use ioctl
2710 : mblume 1490 are not tested at all and might not work (see below).
2711 :    
2712 :     I implemented this since we want to move to a newer version of sml/nj
2713 :     but need socket support in order to use it. This is the first time I
2714 :     even had a look at the sml/nj source, so please review my changes
2715 :     before making this part of the distribution! Here are a few issues
2716 : blume 2155 that I think might be better for someone to solve who is more
2717 : mblume 1490 familiar with the sml/nj source (and socket programming):
2718 :    
2719 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2720 :     exception since I could not figure out what the windows equivalent
2721 :     of these functions is
2722 :    
2723 :     - In sockets-osdep.h there are a some #include statements that are
2724 :     only used in a few files that include sockets-osdep.h
2725 :    
2726 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2727 :     does not process its return value since I don't know how to
2728 :     report an error upwards.
2729 :    
2730 :     - It would probably be good to have a call to WSACleanup() when
2731 : blume 2155 the library is unloaded (if there is such a possibility).
2732 : mblume 1490 Otherwise I think Windows will take care of this automatically
2733 :     when the process finishes.
2734 :    
2735 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2736 :     no idea if that is actually the proper replacement on Windows.
2737 :    
2738 :     - All these issues are marked in the code by "FIXME" comments.
2739 :    
2740 : blume 2155 We use sml/nj extensively in our products and are quite happy
2741 :     with it. I hope this contribution will help you.
2742 : mblume 1490
2743 :     Keep up the good work!

2908 :     Description:
2909 :    
2910 :     Eliminated the "dont_move_libraries" directive in config/targets.
2911 :     (The mechanism was broken and could not be fixed easily. Moreover,
2912 :     there does not seem to be any reason not to move all libraries into
2913 :     lib during installation. I originally implemented this directive as a
2914 :     backward-compatibility feature when I first introduced the new CM.
2915 :     Now that things have been stable for a long time and going back to the
2916 :     old CM is not an option, there is no reason to keep it around.)

2965 :     Tag: blume-20030926-ppautoload
2966 :     Description:
2967 :    
2968 :     I modified the read-eval-print loop so that the autoloader gets
2969 :     invoked whenever the prettyprinter tries to look up a symbol that
2970 :     is not currently defined in the toplevel environment but which
2971 :     appears in CM's autoload registry. As a result, we see far fewer of
2972 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
2973 :    
2974 :     In addition to this I tried to clean up some pieces of the Basis
2975 :     implementation (e.g., Socket, Word8Array) in order to prevent other
2976 :     instances of these ?.Foo.Bar.xxx names from being printed.
2977 :    
2978 :     The mechanism that picks names for types still needs some work, though.
2979 :     (Right now it seems that if there is a type A.t which is defined to
2980 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
2981 :     "?.B.u" although the perhaps more sensible solution would be to use
2982 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
2983 :     a chain of DEFtycs not farther than there are corresponding toplevel
2984 :     names in the current environment.)

2990 :     Description:
2991 :    
2992 :     Another installer tweak: All the ML code for the installer is now
2993 :     compiled during CMB.make and put into a little library called
2994 :     $smlnj/installer.cm. The installation then simply invokes
2995 :    
2996 :     sml -m $smlnj/installer.cm
2997 :    
2998 :     and everything happens automagically.
2999 :    
3000 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3001 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3002 :     and BINDIR.
3003 :    
3004 :     The new scheme guarantees that the ML code responsible for the installation
3005 :     is in sync with the APIs of the main system. Also, the installer is
3006 :     somewhat faster because the installer script is precompiled.

3013 :    
3014 :     Added a signature SYNCHRONOUS_SOCKET to basis.cm. This is like SOCKET
3015 :     but excludes all non-blocking operations. Defined SOCKET (in Basis)
3016 :     and CML_SOCKET in terms of SYNCHRONOUS_SOCKET. Removed superfluous
3017 :     implementations of non-blocking operations from CML's Socket
3018 :     structure.

3023 :     Tag: blume-20030924-sockets
3024 :     Description:
3025 :    
3026 :     1. Fixed SOCKET API and implementation to match Basis spec.
3027 :     This required changing the internal representation of sockets to one
3028 :     that remembers (for each socket file descriptor) whether it is currently
3029 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3030 :     call is made only if the state actually needs to change).
3031 :    
3032 :     2. OS-specific details of sockets were moved into separate files, thus
3033 :     making it possible to unify the bulk of the socket implementations
3034 :     between Unix and Win32.
3035 :    
3036 :     3. CML's socket API changed accordingly.
3037 :     (Note that we need to remove non-blocking functions from this API
3038 :     since they are redundant in the case of CML!)
3039 :    
3040 :     4. CML's socket implementation now makes use of non-blocking functions
3041 :     provided by Basis, thus removing all OS-dependent code from this part
3042 :     of CML.
3043 :    
3044 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3157 :     Description:
3158 :    
3159 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3160 :     Modified config/install.bat to take advantage of it. Also modified
3161 :     config/install.sh (and called it config/new-install.sh) to take advantage
3162 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3163 :     independent.)
3164 :    
3165 :     The installer can now install everything under Win32
3166 :     as well as under *nix as long as it compiles.
3167 :    
3168 :     Other changes:
3169 :    
3170 :     - made CML compile again under Win32
3171 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3172 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3173 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3174 :     same as type int; under Win32 it isn't
3175 :     - fixed some slice-related problems in the win32-specific parts of CML
3176 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3177 :     (under Win32, the volume name is case-insensitive, and the
3178 :     OS.Path code compares volume names for equality)

3195 : mblume 1350 Description:
3196 :    
3197 :     1. Changed interface to vectors and arrays in Basis to match
3198 :     (draft) Basis spec.
3199 :     2. Added signatures and implementations of slices according to
3200 :     Basis spec.
3201 :     3. Edited source code throughout the system to make it compile again
3202 :     under 1. and 2. (In some cases code had to be added to have it
3203 :     match the new signatures.)
3204 :     4. MLRISC should be backward-compatible: the copies of the originals
3205 :     of files that needed to change under 3. were retained, the .cm files
3206 :     check the compiler version number and use old versions when
3207 :     appropriate.
3208 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3209 :     dirstream -> string option (in accordance with Basis spec).
3210 :     6. When generating code that counts lines, ml-lex used function
3211 :     CharVector.foldli, taking advantage of its old interface.
3212 :     This has been replaced with the corresponding code from
3213 :     CharVectorSlice. (html-lex must be re-lexed!)
3214 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3215 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3216 :     8. Removed temporary additions (fromInternal, toInternal) from the
3217 :     (now obsolete) IntInf in smlnj-lib/Util.
3218 :     9. Cleaned up structure Byte.
3219 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3220 :     Cleaned/corrected implementation of Date.
3221 :     (Still need to check for correctness; implement better canonicalizeDate.)
3222 :     11. Added "scan" to signature IEEE_REAL.
3223 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3224 :     mod and rem when second operand is 2 (for parity checks).]
3225 :     13. Changed representation of type Time.time, using a single IntInf.int
3226 :     value counting microseconds. This considerably simplified the
3227 :     implementation of structure Time. We now support negative time
3228 :     values; scan and fromString handle signs.
3229 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3230 :     ArraySlice).

3236 :     Description:
3237 :    
3238 :     This is a major update which comes with a version number bump
3239 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3240 :     and an implementation of IntInf in the Basis.
3241 :    
3242 :     There are a fairly large number of related changes and updates throughout
3243 :     the system:
3244 :    
3245 :     Basis:
3246 :     - Implemented IntInf.
3247 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3248 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3249 : mblume 1347 - Added FixedInt as a synonym for Int32.
3250 :    
3251 :     compiler:
3252 :     * Added support for a built-in intinf type.
3253 :     - literals
3254 :     - pattern matching
3255 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3256 :     - overloading on literals and operations
3257 :    
3258 :     This required adding a primitive type intinf, some additional
3259 :     primops, and implementations for several non-trivial intinf
3260 :     operations in Core. (The intinf type is completely abstract
3261 :     to the compiler; all operations get delegated back to the Core.)
3262 :    
3263 :     * Intinf equality is handled by polyequal. However, the compiler
3264 :     does not print its usual warning in this case (since polyequal
3265 :     is the right thing to do there).
3266 :    
3267 :     * Improved the organization of structure InlineT.
3268 :    
3269 :     * A word about conversion primops:
3270 :     If conversions involving intinf do not cancel out during
3271 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3272 : mblume 1347 Since all core access must be resolved already during the FLINT
3273 :     translate phase, it would be too late a the time of CPS contract
3274 : mblume 1348 to add new Core calls. For this reason, conversion primops
3275 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3276 :     they are supposed to convert, and 2. the Core function that
3277 :     can help with this conversion if necessary. If CPS contract
3278 : mblume 1348 eliminates a primop, then the associated Core function becomes
3279 :     dead and goes away. Intinf conversion primops that do not get
3280 :     eliminated by CPS contract get rewritten into calls of their
3281 :     core functions by a separate, new phase.
3282 : mblume 1347
3283 :     interactive system:
3284 :     - Control.Print.intinfDepth controls max length of intinf constants
3285 :     being printed. (Analogous to Control.Print.stringDepth.)
3286 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3287 :     duplicates; replaced some of the code with code that makes better
3288 :     use of library functionality.
3289 :    
3290 :     CM:
3291 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3292 :     are no longer silent.
3293 :    
3294 :     CKIT:
3295 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3296 :     in favor of LargeInt -- which is now the same as IntInf.
3297 :     CKIT-knowledgable people should check whether this is what's
3298 :     intended and otherwise change things back to using Int32 or
3299 :     FixedInt.
3300 :    
3301 :     Throughout the code:
3302 : mblume 1348 Started using IntInf.int literals and built-in operations
3303 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3322 :     Tag: blume-20030811-windows
3323 :     Description:
3324 :    
3325 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3326 :    
3327 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3328 :    
3329 :     This patch restores SML/NJ's ability to run under win32. There are a
3330 :     number of changes, including fixes for several bugs that had gone
3331 :     unnoticed until now:
3332 :    
3333 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3334 :     trying to run the win32 version from within cygwin.)
3335 :    
3336 :     - There are a number of simple .bat scripts that substitute for their
3337 :     corresponding Unix shell-scripts. (See below.)
3338 :    
3339 :     - The internals of ml-build have been modified slightly. The main
3340 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3341 :     using OS.Process.system, the ML process delegates this task back
3342 :     to the script. Otherwise problems arise in mixed environments such
3343 :     as Cygwin where scripts look and work like Unix scripts, but
3344 :     where OS.Process.system cannot run them.
3345 :    
3346 :     - In CM, the srcpath pickler used native pathname syntax -- which
3347 :     is incorrect in the case of cross-compilation. The new pickle format
3348 :     is independent of platform-specific naming conventions.
3349 :    
3350 :     - Path configuration files (such as lib/pathconfig) can now choose
3351 :     between native and standard syntax. Placing a line of the form
3352 :    
3353 :     standard!
3354 :    
3355 :     into the file causes all subsequent paths to be interpreted using
3356 :     CM standard pathname syntax (= Unix conventions); a line
3357 :    
3358 :     native!
3359 :    
3360 :     switches back to native style. This was needed so that
3361 :     path config files can be written portably, see src/system/pathconfig.
3362 :    
3363 :     - Runtime system:
3364 :    
3365 :     - win32-filesys.c: get_file_time and set_file_time now
3366 :     access modification time, not creation time.
3367 :    
3368 :     - I/O code made aware of new array representation.
3369 :    
3370 :     - Bug fixes in X86.prim.masm.
3371 :    
3372 :     - src/system/makeml made aware of win32. (For use under cygwin
3373 :     and other Unix-environments for windows.)
3374 :    
3375 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3376 :     which caused BinIO.inputAll to fail consistently.
3377 :    
3378 :     .bat scripts:
3379 :    
3380 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3381 :    
3382 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3383 :     applications (sml, ml-yacc, ml-lex).
3384 :     - ml-build.bat: analogous to ml-build.
3385 :     - config\install.bat: Analogous to config/install.sh. This requires
3386 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3387 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3388 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3389 :     and the bootfile hierarchy must have been unpacked under
3390 :     sml.boot.x86-win32.
3391 :     The script is very primitive and does a poor job at error checking.
3392 :     It only installs the base system, ml-lex, and ml-yacc. No other
3393 :     libraries are being installed (i.e., you get only those that
3394 :     are part of the compiler.)
3395 :     - link-sml.bat: analogous to .link-sml, but not currently used
3396 :    
3397 :     Unrelated bug fixes:
3398 :    
3399 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3400 :     types.
3401 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3402 :     otherwise.)

3426 :     Description:
3427 :    
3428 :     Two changes:
3429 :    
3430 :     1. Added a flag for controlling whether non-exhaustive bindings will
3431 :     be treated as errors (default is false).
3432 :     2. Cleaned up the *entire* source tree so that CMB.make goes through

3439 :     Description:
3440 :    
3441 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3442 :    
3443 :     This mainly affects the quality of error messages. However, some
3444 :     of the code is now more straightforward than before. (Treatment of
3445 :     the above four constructs in translate.sml is much simpler than
3446 :     the "macro-expansion" that was going on before. Plus, the mach-
3447 :     compiler no longer gets invoked just to be able to compile an
3448 :     if-expression.)
3449 :    
3450 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3451 :     interactive loop.

3461 :    
3462 : blume 2155 o getnetbyname, getnetbyaddr: these functions seem to be missing in
3463 : allenleung 1327 the Cygwin library.
3464 :     o Ctrl-C handling may be flaky.
3465 :     o Windows system calls and Windows I/O are not supported.
3466 :    
3467 :     A new set of binfiles is located at:
3468 :    
3469 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3470 :    
3471 :     This is only needed for bootstrapping the cygwin version of smlnj.

3513 :     This fixes the problem of CM getting confused by files that suddenly
3514 :     change their identity (e.g., by getting unlinked and recreated by some
3515 :     text editor such as vi). There might be a better/cheaper/cleaner way

3695 :    
3696 :     - Added ControlUtil structure to control-lib.cm.
3697 :     - Use it throughout.
3698 :     - Used Controls facility to define MLRISC controls (as opposed to
3699 :     registering MLRISC control ref cells with Controls after the fact)
3700 :     - Fixed messed-up controls priorities.
3701 :    
3702 :     * Removed again all the stuff from config/preloads that one wouldn't
3703 :     be able to preload at the time the initial heap image is built.
3704 :     (Many libraries, e.g., CML, do not exist yet at this time. The
3705 :     only libraries that can be preloaded via config/preloads are those
3706 :     that come bundled with the bootfiles.)

3732 :    
3733 :     0. John Reppy made several modifications to the SML/NJ library.
3734 :     In particular, there is a shiny new controls-lib.cm.
3735 :    
3736 :     1. Pushed new controls interface through compiler so that everything
3737 :     compiles again.
3738 :    
3739 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3740 :     SML/NJ library (so that CML compiles again).
3741 :    
3742 :     3. Modified init scripts because XXX_DEFAULT environment variables
3743 :     are no longer with us. (Boot-time initialization is now done
3744 :     using the same environment variables that are also used for
3745 :     startup-time initialization of controls.)

3751 :     Description:
3752 :    
3753 :     All pseudo-ops emitted before the first segment declaration
3754 :     such as TEXT, DATA, and BSS directives are assumed to be global
3755 :     declarations and are emitted first in the assembly file. This is
3756 :     useful in a number of situations where one has pseudo-ops that are not
3757 :     specific to any segment, and also works around the constraint that one
3758 :     cannot have client pseudo-ops in the TEXT segment.
3759 :    
3760 :     Because no segment is associated with these declarations it is
3761 :     an error to allocate any space or objects before the first segment
3762 :     directive and an exception will be raised. However, we cannot make
3763 :     this check for client pseudo-ops.
3764 :    
3765 :     These top level declarations are a field in the CFG graph_info.
3766 :     In theory you can continue to add to this field after the CFG has been
3767 :     built -- provided you know what you are doing;-)

3777 :     - Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
3778 :     (Bogus printouts for redefined bindings still occur. Compiler
3779 :     bug should no longer occur now. We need to redo the prettyprinter
3780 :     from scratch.)
3781 :

3789 :     Tag: blume-20020510-erg-textio
3790 :     Description:
3791 :    
3792 :     Applied the following bugfix provided by Emden Gansner:
3793 :    
3794 :     Output is corrupted when outputSubstr is used rather than output.
3795 :    
3796 : blume 2155 The problem occurs when a substring
3797 : blume 1189
3798 :     ss = (s, dataStart, dataLen)
3799 :    
3800 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3801 :     avail bytes of s, starting at index dataStart, are copied into the
3802 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3803 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3804 :     starting this copy at index dataStart+avail in s, the current code
3805 : blume 1189 starts the copy at index avail.
3806 :    
3807 :     Fix:
3808 :     In text-io-fn.sml, change line 695 from
3809 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3810 : blume 2155 to
3811 : blume 1189 val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

3826 :     Tag: blume-20020401-x86div
3827 :     Description:
3828 :    
3829 :     Added full support for div/mod/rem/quot on the x86, using the machine
3830 :     instruction's two results (without clumsily recomputing the remainder)
3831 :     directly where appropriate.
3832 :    
3833 :     Some more extensive power-of-two support was added to the x86 instruction
3834 :     selector (avoiding expensive divs, mods, and muls where they can be
3835 :     replaced with cheaper shifts and masks). However, this sort of thing
3836 :     ought to be done earlier, e.g., within the CPS optimizer so that
3837 :     all architectures benefit from it.
3838 :    
3839 :     The compiler compiles to a fixed point, but changes might be somewhat
3840 :     fragile nevertheless. Please, report any strange things that you might
3841 :     see wrt. div/mod/quot/rem...

3847 :     Description:
3848 :    
3849 :     Fixed my broken div/mod logic. Unfortunately, this means that the
3850 :     inline code for div/mod now has one more comparison than before.
3851 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3852 :     The problem was with quotient = 0, because that alone does not tell
3853 :     us which way the rounding went. One then has to look at whether
3854 :     remainder and divisor have the same sign... :(
3855 :

3862 :     Description:
3863 :    
3864 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
3865 :    
3866 :     Primops have changed. This means that the bin/boot-file formats have
3867 :     changed as well.
3868 :    
3869 :     To make sure that there is no confusion, I made a new version.
3870 :    
3871 :    
3872 :     CHANGES:
3873 :    
3874 :     * removed REMT from mltree (remainder should never overflow).
3875 :    
3876 :     * added primops to deal with divisions of all flavors to the frontend
3877 :    
3878 :     * handled these primops all the way through so they map to their respective
3879 :     MLRISC support
3880 :    
3881 :     * used these primops in the implementation of Int, Int32, Word, Word32
3882 :    
3883 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3884 :    
3885 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
3886 :    
3887 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3888 :     floating point
3889 :    
3890 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3891 :     and Real (but Real.abs maps to a separate floating-point-only primop)
3892 :    
3893 :    
3894 :     TODO items:
3895 :    
3896 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
3897 :     instructions because the machine instruction encoder cannot handle
3898 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
3899 :     REM in the first place, and REM is supported by the x86 machine coder.)
3900 :    
3901 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
3902 :     selection phase. (The two can be streamlined because the hardware
3903 :     delivers both quotient and remainder at the same time anyway.)
3904 :    
3905 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
3906 :     (Currently the behavior is inconsistent both across architectures and
3907 :     wrt. the draft Basis spec.)
3908 :    
3909 :     * Word8 should eventually be handled natively, too.
3910 :    
3911 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
3912 :     as if there currently is no execution path that could trigger it in
3913 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
3914 :     hold for things like multiplication and division.)

3919 :     Tag: blume-20020327-mlrisc-divisions
3920 :     Description:
3921 :    
3922 :     Added support for all four division operations (ML's div, mod, quot,
3923 :     and rem) to MLRISC. In the course of doing so, I also rationalized
3924 :     the naming (no more annoying switch-around of DIV and QUOT), by
3925 :     parameterizing the operation by div_rounding_mode (which can be either
3926 :     DIV_TO_ZERO or DIV_TO_NEGINF).
3927 :    
3928 :     The generic MLTreeGen functor takes care of compiling all four
3929 :     operations down to only round-to-zero div.
3930 :    
3931 :     Missing pieces:
3932 :    
3933 :     * Doing something smarter than relying on MLTreeGen on architectures
3934 :     like, e.g., the x86 where hardware division delivers both quotient and
3935 :     remainder at the same time. With this, the implementation of the
3936 :     round-to-neginf operations could be further streamlined.
3937 :    
3938 :     * Remove inlining support for div/mod/rem from the frontend and replace it
3939 :     with primops that get carried through to the backend. Do this for all
3940 :     int and word types.

3945 :     Tag: blume-20020325-divmod
3946 :     Description:
3947 :    
3948 :     I improved (hopefully without breaking them) the implementation of Int.div,
3949 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
3950 :     advantage of the following observations:
3951 :    
3952 :     Let q = x quot y r = x rem y
3953 :     d = x div y m = x mod y
3954 :    
3955 :     where "quot" is the round-to-zero version of integer division that
3956 :     hardware usually provides. Then we have:
3957 :    
3958 :     r = x - q * y where neither the * nor the - will overflow
3959 :     d = if q >= 0 orelse x = q * y then q else q - 1
3960 :     where neither the * nor the - will overflow
3961 :     m = if q >= 0 orelse r = 0 then r else r + y
3962 :     where the + will not overflow
3963 :    
3964 :     This results in substantial simplification of the generated code.
3965 :     The following table shows the number of CFG nodes and edges generated
3966 :     for
3967 :     fun f (x, y) = x OPER y
3968 :     (* with OPER \in div, mod, quot, rem *)
3969 :    
3970 :    
3971 :     OPER | nodes(old) | edges(old) | nodes(new) | edges(new)
3972 :     --------------------------------------------------------

4010 :    
4011 :     1. Changes to FLINT primops:
4012 :    
4013 :     (* make a call to a C-function;
4014 :     * The primop carries C function prototype information and specifies
4015 :     * which of its (ML-) arguments are floating point. C prototype
4016 :     * information is for use by the backend, ML information is for
4017 :     * use by the CPS converter. *)
4018 :     | RAW_CCALL of { c_proto: CTypes.c_proto,
4019 :     ml_args: ccall_type list,
4020 :     ml_res_opt: ccall_type option,
4021 :     reentrant : bool
4022 :     } option
4023 :     (* Allocate uninitialized storage on the heap.
4024 :     * The record is meant to hold short-lived C objects, i.e., they
4025 : blume 2155 * are not ML pointers. With the tag, the representation is
4026 : leunga 1174 * the same as RECORD with tag tag_raw32 (sz=4), or tag_fblock (sz=8)
4027 :     *)
4028 : blume 2155 | RAW_RECORD of {tag:bool,sz:int}
4029 : leunga 1174 and ccall_type = CCALL_INT32 | CCALL_REAL64 | CCALL_ML_PTR
4030 :    
4031 :     2. These CPS primops are now overloaded:
4032 :    
4033 :     rawload of {kind:numkind}
4034 :     rawstore of {kind:numkind}
4035 :    
4036 :     The one argument form is:
4037 :    
4038 :     rawload {kind} address
4039 :    
4040 :     The two argument form is:
4041 : blume 2155
4042 : leunga 1174 rawload {kind} [ml object, byte-offset]
4043 :    
4044 :     3. RAW_CCALL/RCC now takes two extra arguments:
4045 :    
4046 :     a. The first is whether the C call is reentrant, i.e., whether
4047 :     ML state should be saved and restored.
4048 :     b. The second argument is a string argument specifying the name of
4049 :     library and the C function.
4050 :    
4051 :     These things are currently not handled in the code generator, yet.
4052 :    
4053 :     4. In CProto,
4054 :    
4055 : blume 2155 An encoding type of "bool" means "ml object" and is mapped into
4056 :     C prototype of PTR. Note that "bool" is different than "string",
4057 : leunga 1174 even though "string" is also mapped into PTR, because "bool"
4058 :     is assigned an CPS type of BOGt, while "string" is assigned INT32t.
4059 :    
4060 :     5. Pickler/unpicker
4061 :    
4062 :     Changed to handle RAW_RECORD and newest RAW_CCALL
4063 :    
4064 :     6. MLRiscGen,
4065 :    
4066 :     1. Changed to handle the new rawload/rawstore/rawrecord operators.
4067 :     2. Code for handling C Calls has been moved to a new module CPSCCalls,
4068 :     in the file CodeGen/cpscompile/cps-c-calls.sml
4069 :    
4070 :     7. Added the conditional move operator
4071 :    
4072 :     condmove of branch

4093 :     fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)
4094 :    
4095 :     the ball-larus heuristics predicts that the n=0 is unlikely
4096 :     (OH-heuristic), and the 'then' branch is unlikely because of the
4097 :     RH-heuristic -- giving the 'then' branch an even lower combined
4098 : george 1171 probability using the Dempster-Shafer theory.
4099 : george 1168
4100 :     Finally, John Reppy's loop analysis in MLRISC, further lowers the
4101 :     probability of the 'then' branch because of the loop in the else
4102 :     branch.

4105 :     Graphical Viewing:
4106 : blume 2155 ------------------
4107 : george 1168 I merely plugged in Allen's graphical viewers into the compiler. The
4108 :     additional code is not much. At the top level, saying:
4109 :    
4110 :     Control.MLRISC.getFlag "cfg-graphical-view" := true;
4111 :    
4112 :     will display the graphical view of the control flow graph just before
4113 :     back-patching. daVinci must be in your path for this to work. If
4114 :     daVinci is not available, then the default viewer can be changed
4115 :     using:
4116 :    
4117 :     Control.MLRISC.getString "viewer"
4118 :    
4119 :     which can be set to "dot" or "vcg" for the corresponding viewers. Of
4120 :     course, these viewers must be in your path.
4121 :    
4122 :     The above will display the compilation unit at the level of clusters,
4123 :     many of which are small, boring, and un-interesting. Also setting:
4124 :    
4125 :     Control.MLRISC.getInt "cfg-graphical-view_size"
4126 :    
4127 :     will display clusters that are larger than the value set by the above.

4150 :     Tag: leunga-20020321-x86-fp-cfg
4151 :     Description:
4152 :    
4153 : blume 2155 1. Recoded the buggy parts of x86-fp.
4154 : leunga 1156
4155 :     a. All the block reordering code has been removed.
4156 :     We now depend on the block placement phases to do this work.
4157 :    
4158 :     b. Critical edge splitting code has been simplified and moved into the
4159 :     CFG modules, as where they belong.
4160 :    
4161 :     Both of these were quite buggy and complex. The code is now much, much
4162 :     simpler.
4163 :    
4164 :     2. X86 backend.
4165 :    
4166 :     a. Added instructions for 64-bit support. Instruction selection for
4167 :     64-bit has not been committed, however, since that
4168 : blume 2155 requires changes to MLTREE which haven't been approved by
4169 : leunga 1156 Lal and John.
4170 :    
4171 : blume 2155 b. Added support for FUCOMI and FUCOMIP when generating code for
4172 : leunga 1156 PentiumPro and above. We only generate these instructions in
4173 :     the fast-fp mode.
4174 :    
4175 : blume 2155 c. Added cases for JP and JNP in X86FreqProps.
4176 :    
4177 : leunga 1156 3. CFG
4178 :    
4179 :     CFG now has a bunch of methods for edge splitting and merging.
4180 :    
4181 :     4. Machine description.
4182 :    
4183 :     John's simplification of MLTREE_BASIS.fcond broke a few machine
4184 :     description things:
4185 :    
4186 :     rtl-build.{sig,sml} and hppa.mdl fixed.
4187 :    
4188 : blume 2155 NOTE: the machine description stuff in the repository is still broken.
4189 :     Again, I can't put my fixes in because that involves
4190 :     changes to MLTREE.
