228 : blume 2692 Date: 2007/06/06 21:45:00 CDT
229 :     Description:
230 :    
231 :     - Aaron: fixed a number of bugs in ml-ulex.
232 :     - Matthias:
233 :     - added CM control "cm.force-tools"; this is false by default;
234 :     when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
235 :     will be forced to run regardless of whether or not their targets
236 :     are up-to-date
237 :     - changed installer code so that config/install.sh will re-build
238 :     heap images for all tools even if those heap images already existed
239 :    
240 :     ----------------------------------------------------------------------
241 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
242 : blume 2688 Date: 2007/06/04 21:21:00 CDT
243 :     Description:
244 :    
245 :     After Aaron Turon's bug fix for ml-ulex (handling the ^ character
246 :     in legacy mode), re-ran the lexer generator on all lex input files
247 :     and committed the results.
248 :    
249 :     This should fix the problem with ckit and nlffi that was reported
250 :     by Vesa A. Norrman.

261 : dbm 2650 Name: Dave MacQueen (dbm@cs.uchicago.edu)
262 :     Date: 2007/05/31 14:55:00 CDT
263 :     Revision: 2650
264 :     Description:
265 :    
266 :     3rd merge of base from primop-branch-3 into the trunk.
267 :     Additional bug fixes included:
268 :    
269 :     * Timer.cpu_timer, etc. type printing corrected (by making
270 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
271 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
272 :     Stefan Monnier)
273 :    
274 :     ----------------------------------------------------------------------
275 : blume 2645 Name: Matthias Blume (http://www.tti-c.org/blume/)
276 :     Date: 2007/05/31 11:40:00 CDT
277 :     Description:
278 :    
279 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
280 :    
281 :     Also, changed the handling of "no core access": When translate.sml
282 :     needs access to a core exception at a time when the core has not
283 :     been set up yet (this only happens when compiling system/smlnj/init/*),
284 :     then don't bother generating the corresponding tests.
285 :    
286 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
287 :     the exception. Unfortunately, that confuses the plambda type checker.
288 :     Moreover, it does not do any good, because at runtime we don't expect
289 :     such an exception to be ever raised. (The code in system/smlnj/init/*
290 :     has to be written very carefully with this in mind!)

293 : mrainey 2639 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
294 :     Date: 2007/05/29
295 :     Description:
296 :    
297 :     Added FSQRT instructions for the AMD64 code generator.

300 : blume 2626 Name: Matthias Blume (http://www.tti-c.org/blume/)
301 :     Date: 2007/05/29 19:00:00 CDT
302 :     Description:
303 :    
304 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
305 :     with an explicit test for zero division. This should fixes several
306 :     regressions and makes it possible for downstream optimization phases
307 :     to treat these operations as "pure" when they are applied to unsigned
308 :     operands.

310 :     ----------------------------------------------------------------------
311 : mrainey 2622 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
312 :     Date: 2007/05/29
313 :     Description:
314 :    
315 :     Added the new MLRISC code generator for the AMD64. This version,
316 :     in contrast to the previous one, uses SSE registers and instructions
317 :     for all floating-point computations.

320 : jhr 2613 Name: John Reppy (http://www.cs.uchicago.edu/~jhr)
321 : jhr 2617 Date: 2007/05/29
322 : jhr 2613 Description:
323 :    
324 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
325 :     for bugs #1415 and #1416. We also now correctly handle format characters that
326 :     lie outside the specified set.

329 : blume 2610 Name: Matthias Blume (http://www.tti-c.org/blume/)
330 :     Date: 2007/05/23 22:30:00 CDT
331 :     Description:
332 :    
333 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
334 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
335 :    
336 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
337 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
338 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
339 :     while running CMB.make. The point is that the single symbol
340 :     NO_PLUGINS is definde in all three cases.)
341 :    
342 :     I changed the three locations within the sources that get compiled
343 :     during CMB.make where ml-yacc or ml-lex input is processed: When
344 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
345 :     is bypassed.
346 :    
347 :     When bootstrapping new versions of the compiler, there can be
348 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
349 :     are not available or otherwise not operational. In this case one can
350 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
351 :     do so, the following command should be issued at the interactive
352 :     prompt:
353 :    
354 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
355 :    
356 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
357 :     files that normally would be generated by ml-yacc and ml-lex.
358 :     (Copies of these files are in the repository.)

362 :     Date: 2007/5/23 17:23:00 CDT
363 :     Revision: 2603
364 :     Description:
365 :    
366 :     2nd merge of base from primop-branch-3 into the trunk.
367 :     Additional bug fixes included:
368 :     Date.scan and Date.fromString fixed;
369 :     Overloading resolution fixed and some type printing problems corrected.

373 : blume 2589 Date: 2007/05/23 09:50:00 CDT
374 :     Description:
375 :    
376 :     Changed the installation mechanism for CM tool plugins. These are
377 :     just libaries and now get installed like ordinary libaries.
378 :    
379 :     There are now a number of new installation targets that give some
380 :     fine-grain control over what classes and suffixes are known, and what
381 :     they will map to.
382 :     See config/targets for details.
383 :    
384 :     The code that caused plugin installation as part of running a
385 :     tool's "build" script has been removed. (The build script is for
386 :     building, not for installing.)
387 :    
388 :     ----------------------------------------------------------------------
389 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
390 : blume 2578 Date: 2007/05/22 11:50:00 CDT
391 :     Description:
392 :    
393 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
394 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
395 :     CM fail if a shell tool reports a non-success exit status. If
396 :     the control is set to true, then CM will press on after tool failures
397 :     in the event that the target files exist (even though they are
398 :     considered outdated). Turning the control to true can be useful for
399 :     bootstrapping.

403 :     Date: 2007/05/19
404 :     Description:
405 :    
406 :     Merge of ml-lpt revisions for 110.64.
407 :    
408 :     The name of several ml-lpt-lib modules has changed:
409 :     Repair => AntlrRepair
410 :     StreamPos => AntlrStreamPos
411 :     ErrHandlerFn => AntlrErrHandler
412 :     EBNF => AntlrEBNF
413 :    
414 :     The ml-antlr specification format has changed: declarations such as
415 :     %tokens and nonterminal definitions can occur *multiple* times in the
416 :     same specification. The semantics are such that each new declaration
417 :     extends the previous ones. This does not apply to %start or %name,
418 :     of course.
419 :    
420 :     Importing a grammar via %import now includes *all* declarations in from
421 :     the imported grammar, except for %name, %entry, and %start. Tokens
422 :     and nonterminals can be dropped using the new %dropping clause of the
423 :     %import directive; the separate %drop and %extend have been removed.
424 :    
425 :     We now allow optional type annotations on nonterminals, using the %nonterms
426 :     directive as in ml-yacc.
427 :    
428 :     The refcell construct is now implemented using SML's regular reference
429 :     cells, so the :== and !! notation has been deprecated.
430 :    
431 :     The ml-antlr tool now does much more checking of specifications, and
432 :     its error messages have been greatly improved. Error repair for
433 :     generated parsers has been completely rewritten, and is now both
434 :     much faster and more accurate.
435 :    
436 :     ml-ulex is now more lenient with escape codes (non-SML-standard
437 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
438 :     Also, character classes may now include a "-" character at the beginning
439 :     as is standard in most other regexp tools.
440 :    
441 :     All of these changes are documented in the user guide, which has
442 :     been updated and improved with this merge.

448 :     Description:
449 :    
450 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
451 :     Significant changes in FLINT and the front end, mostly having to do
452 :     with a reorganized system for handling primops. Various bug fixes
453 :     and improvements in printing signatures.

458 :     Description:
459 :    
460 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
461 :     The ml-antlr specification format has changed: declarations such as
462 :     %tokens and nonterminal definitions can occur *multiple* times in the
463 :     same specification. The semantics are such that each new declaration
464 :     extends the previous ones. Grammar extension constructs have also
465 :     changed. We now allow type annotations on nonterminals. Finally,
466 :     the refcell construct is now implemented using SML's regular reference
467 :     cells, so the :== and !! notation has been deprecated. All of these
468 :     changes will appear in the 110.64 user guide for ml-lpt.
469 :    
470 :     The ml-antlr tool now does much more checking of specifications, and
471 :     its error messages have been greatly improved. There has also been
472 :     some work on the error repair process for generated parsers, but this
473 :     will be further improved in 110.64.

593 :     Description:
594 :    
595 :     Added preliminary support in MLRISC for Staged Allocation, a technique
596 :     for specifying calling conventions (see
597 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
598 :     Initially, we plan to use this code to generate C calls for the AMD64.
599 :    
600 :     The staged allocation code base resides in MLRISC/staged-allocation,
601 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

607 :

621 :    
622 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
623 :     of the range -128 ... 127. I've changed the code so that the range
624 :     check is disabled. Only the low order 8 bits of the immediate operand

665 :     Date: 2007/01/31
666 :     Description:
667 :    
668 :     Brought ml-lpt manual up-to-date with the code. Many minor
669 :     improvements to the tools, and a few minor bugfixes. Prepared
670 :     ml-lpt-lib for integration with new UTF8 structure. Changed
671 :     the interface for creating streams in ml-ulex (we now support
672 :     stream creation from several kinds of sources). Overall, the
673 :     tools are now quite stable, and their interfaces are unlikely to
674 :     change in a way that would break compatibility. More work,
675 :     however, is needed in the documentation.

680 :     Description:
681 :    
682 :     Implemented library installer. Moved CM plugin code for
683 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
684 :     their respective trees. Implemented CM plugin for ml-ulex
685 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
686 :     and ml-antlr.
687 :    
688 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
689 :     CM tools. (It turns out to be too messy to do otherwise because
690 :     there is too much code that during installation relies on the presence
691 :     of these tools -- resulting in a tricky ordering problem.)

696 :     Description:
697 :    
698 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
699 :     Modified CM's startup code to use shiftArgs as it processes
700 :     command line arguments. This way, the init code in each .sml-file
701 :     or library that is mentioned at the top level will see only
702 :     those arguments that have not yet been processed at this point.
703 :     In other words, the init code can "seize control" and process the
704 :     remaining command line.

718 :    
719 :     Added the UTF8 structure and signature from the Moby compiler to
720 :     the SML/NJ library (and the CML library). These modules will replace
721 :     the version in the ml-lpt-lib.

770 :     Date: 2006/12/08 09:50:00 CST
771 :     Description:
772 :    
773 :     Added code to CM's "standard shell tool" implementation which
774 :     causes it to tolerate (with a warning) the situation where the shell
775 :     command fails (e.g., due to the shell command's non-existence)
776 :     as long as all target files exist.
777 :    
778 :     This makes it possible to, e.g., build ml-yacc from sources even if
779 :     svn checkout messed up the time stamps on files in such a way that
780 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
781 :     be needed to re-process yacc.grm, but obviously it might not yet be
782 :     available at that time.)

788 :    
789 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
790 :     recvVecFromNB' in the SOCKET signature. This error is actually
791 :     in the SML Basis specification too.

866 :     LL(k) parser generator). These tools are currently "beta-quality"
867 :    
868 :     The latest versios of the sources can now be obtained anonymously
869 :     via subversion. For this, it is useful to first check out
870 :    
871 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
872 :    
873 :     and put the resulting directory on your shell's PATH. This provides
874 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
875 :     and refresh-all.sh.
876 :    
877 :     To create a freshly checked-out copy of the sources, do
878 :    
879 :     checkout-all.sh [dir]
880 :    
881 :     where dir is the optional SML/NJ root directory (default is ".").
882 :    
883 :     This creates the above directory layout. Each subdirectory of
884 :     the root is under individual subversion control. The stat-all.sh
885 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
886 :     each of these subtrees.

890 : blume 2155 Date: 2006/11/02 12:20:00 CST
891 :     Description:
892 :    
893 :     Reorganized directory layout.
894 :    
895 :     This is a temporary solution, more reorganization is to come.
896 :    
897 :     The basic idea is to have a number of toplevel trees, each corresponding
898 :     to a well-defined part of the overall system. Each part can be
899 :     maintained individually, even in separate source repositories,
900 :     although currently we still serve everything out of the main
901 :     smlnj-gforge tree.
902 :    
903 :     Installer and and scripts have been updated to reflect the new
904 :     layout. The installer (base/src/system/smlnj/installer) is now
905 :     "scriptable" to avoid burning too much knowledge about the
906 :     layout into SML source code. The main script used by the installer
907 :     is in config/actions.
908 :    
909 :     The main change is that many of the subdirectories of what used to
910 :     be known as "src" have moved to the toplevel. The "src" directory
911 :     itself has moved down into a subtree called "base". (We may eventually
912 :     get rid of the extra level of indirection represented by "src".)
913 :    
914 :     The layout is now as follows:
915 :    
916 :     toplevel tree name | default repository
917 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
918 :     -------------------+----------------------------------------------------
919 :     config | $gf/config/trunk
920 :     |
921 :     base | $gf/sml/trunk
922 :     |
923 :     smlnj-lib | $gf/smlnj-lib/trunk
924 :     MLRISC | $gf/MLRISC/trunk
925 :     |
926 :     ml-yacc | $gf/ml-yacc/trunk
927 :     ml-lex | $gf/ml-lex/trunk
928 :     ml-burg | $gf/ml-burg/trunk
929 :     lexgen | $gf/lexgen/trunk
930 :     heap2asm | $gf/heap2asm/trunk
931 :     |
932 :     cml | $gf/cml/trunk
933 :     eXene | $gf/eXene/trunk
934 :     ckit | $gf/ckit/trunk
935 :     nlffi | $gf/nlffi/trunk
936 :     |
937 :     smlnj-c | $gf/smlnj-c/trunk
938 :    
939 :     In $gf/admin there are a few useful shell scripts for checking out
940 :     and maintaining the entire collection of trees:
941 :    
942 :     admin/checkout-all.sh [dir]
943 :     -- optionally creates dir and checks out all trees from their
944 :     default repositories; if dir is missing, checkout into .
945 :     admin/refresh-all.sh [dir]
946 :     -- looks at all trees (from the above list) in dir (default: .)
947 :     and runs "svn update" if the tree exists and is under
948 :     subversion control;
949 :     non-existing or non-subversion trees are skipped
950 :     admin/stat-all.sh [dir]
951 :     -- like refresh-all.sh, but runs "svn stat" instead

1134 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1135 : blume 2155 at the time when config/preloads is processed, the library has to
1136 : mblume 1878 be referred to by another name. In 110.57 this would be
1137 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm

1194 :     Description:
1195 :    
1196 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1197 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1198 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1199 :     it. Instead, it has the status of "user code", so it should use
1200 :     $/basis.cm to refer to the Basis library. (At least that's true for
1201 :     the purpose of bootstrapping the previous change. In the future it
1202 :     might make sense to have versiontool.cm refer to
1203 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1204 :     compiler itself uses.)

1207 :     bindings in config/extrapathconfig.

1212 :     Tag: blume-22051115-libraries
1213 :     Description:
1214 :    
1215 :     This change affects the way the following libraries are tied into
1216 :     the system:
1217 :    
1218 :     $/basis.cm
1219 :     $/smlnj-lib.cm
1220 :     $/pp-lib.cm
1221 :     $/controls-lib.cm
1222 :     $/html-lib.cm
1223 :     $/ml-yacc-lib.cm
1224 :    
1225 :     These libraries are now internally (as seen from the source code
1226 :     of the implementation itself) known by the following names:
1227 :    
1228 :     $smlnj/basis/basis.cm
1229 :     $smlnj/smlnj-lib/smlnj-lib.cm
1230 :     $smlnj/smlnj-lib/pp-lib.cm
1231 :     $smlnj/smlnj-lib/controls-lib.cm
1232 :     $smlnj/smlnj-lib/html-lib.cm
1233 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1234 :    
1235 :     This makes it possible to work with code that requires different
1236 :     versions of these libraries, and which refers to these libraries using
1237 :     their "default" names (i.e., the first set of names above). In other
1238 :     words, one can un-define or re-define those default names without
1239 :     compromising the proper functioning of the compiler itself.
1240 :    
1241 :     A similar procedure had already been performed for several of the
1242 :     MLRISC libraries that are linked into the compiler. I did some
1243 :     cleanup on this code.
1244 :    
1245 :     A new file in the config directory (named extrapathconfig) is
1246 :     responsible for setting up path anchors that the compiler itself does
1247 :     not need, but that are typically required by user code.

1426 :     Tag: blume-20050516-redump-heap
1427 :     Description:
1428 :    
1429 :     Added mechanism for re-creating a heap file for the interactive system
1430 :     after configuration variables have been changed.
1431 :    
1432 :     CM.redump_heap : string -> unit
1433 :    
1434 :     This is much like SMLofNJ.exportML, but starting from the resulting
1435 : blume 2155 heap does not return to the caller of CM.redump_heap but
1436 : mblume 1792 restarts the interactive system from scratch. The original call of
1437 :     CM.redump_heap does not return but ends the interactive session.
1438 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1439 :    
1440 :     Internally, redump_heap winds the dynamic execution context back to
1441 :     the point where the original heap image was created and re-executes
1442 :     the heap image generation code in the boot code.

1558 :     Tag: blume-20050114-heap2exec
1559 :     Description:
1560 :    
1561 :     Implemented new (but still experimental) heap2exec facility. This is
1562 :     tested under Mac OS X and should work under Linux (will test shortly).
1563 :     It will probably also work on the Sparc (will test some time later).
1564 :    
1565 :     - removed old "HACKED_STANDALONE" hack from runtime
1566 :    
1567 :     To be able to test this, uncomment the request for "heap2asm" in
1568 :     config/targets prior to installation. (Notice that this is different
1569 :     from "heap2exec" mentioned below. Not a typo.)
1570 :    
1571 :     To perform an actual test, run the command
1572 :    
1573 :     $ bin/heap2exec heapfile execfile
1574 :    
1575 :     (You can put heap2exec on your shell's path.)
1576 :    
1577 :     For example, run
1578 :    
1579 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1580 :    
1581 :     This will create a standalone executable called "mly" which you can
1582 :     then invoke directly as a command.

1609 :    
1610 :     * Fixed CM's incorrect assumption that the PPC is little-endian.

1678 :     Description:
1679 :    
1680 :     Hacked some of the scripts (in particular: the installer) to cope with
1681 :     spaces in filenames a bit better. But beware: the current "solution"
1682 :     is likely still full of bugs and inherently incomplete. (We need to
1683 :     do away with those shell scripts for a comprehensive solution.)

1727 :     Tag: blume-20041124-position
1728 :     Description:
1729 :    
1730 :     The compiler can now be compiled in a mode that makes structure Position
1731 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1732 :     for the time being.
1733 :    
1734 :     To enable 64-bit positions, use the following procedure:
1735 :    
1736 :     1. Start sml
1737 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1738 :     3. Type
1739 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1740 :     4. Run CMB.make() as usual.
1741 :    
1742 :     This is barely tested. The only test so far was a little SML program
1743 :     counting the number of characters in an 8-gigabyte file by
1744 :     reading it character-by-character. That test was successful.
1745 :    
1746 :     In support of 64-bit positions, a number of new functions have been
1747 :     added to the runtime system.

1788 :     Description:
1789 :    
1790 :     - Stripped down the versiontool: It now only handles the version number.
1791 :     The date string is generated at bootstrap time (during makeml).
1792 :    
1793 :     - In a previous commit, fixed a minor issue with how polyequal is being
1794 :     translated. In particular, the code now "looks through" abstractions.
1795 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1796 :     more efficient code. Important examples for where this matters are
1797 :     the new int64 and word64 types.

1812 :     Description:
1813 :    
1814 :     All the pieces of Word64 are now there, with the exception of the
1815 :     conversions from and to LargeWord. (Eventually these need to be identities,
1816 :     but for the time being they don't even make sense because LargeWord is
1817 :     32-bit wide.)
1818 :    
1819 :     Also started to add similar support for Int64, but major pieces of that
1820 :     are still missing.

1825 :     Tag: blume-20041111-word64
1826 :     Description:
1827 :    
1828 :     Structure Word64 is now (almost) complete, word literals and patterns
1829 :     seem to work. There are a few odd pieces missing. In particular,
1830 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1831 :     at the moment.
1832 :    
1833 :     Making Word64 official would mean that LargeWord becomes Word64. But
1834 :     this requires extreme care because most word-word conversions have to
1835 :     go through LargeWord, so making a mistake means loss of efficiency or
1836 :     worse. Eventually there will be a solution similar to (but actually
1837 :     simpler than) what I did with IntInf.

1872 :     - Made corresponding changes to config/install.sh and config/unpack.
1873 :     - Default contents of config/srcarchiveurl uses $VERSION and
1874 :     normally does not have to be edited to reflect a version change.
1875 :    
1876 :     (As a result, a version change can be done by just editing
1877 :     config/version, the rest is now automatic.)

1917 :     Tag: blume-20041020-standalone-backtrace
1918 :     Description:
1919 :    
1920 :     Added a mechanism for getting back-trace information from standalone
1921 :     programs. Here is how it works:
1922 :    
1923 :     1. The part of the program from which you want to get backtrace
1924 :     information (usually the whole program) should be wrapped with
1925 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
1926 :     main program could be modified from something like
1927 :    
1928 :     fun main (pgm, args) = ...
1929 :    
1930 :     to
1931 :    
1932 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1933 :    
1934 :     2. To be able to access BackTrace.monitor, you have to add
1935 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
1936 :     main function.
1937 :    
1938 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1939 :     CM might have created in the past for your project).
1940 :    
1941 :     4. Build the system using this command line:
1942 :    
1943 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1944 :     myprog.cm MyProg.main myprog
1945 :    
1946 :     instead of the usual
1947 :    
1948 :     ml-build myprog.cm MyProg.main myprog
1949 :    
1950 :     I changed a library name:
1951 :    
1952 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1953 :    
1954 :     New libraries:
1955 :    
1956 :     $smlnj-tdp/back-trace.cm
1957 :     -- when loaded causes the back-trace plugin to be installed
1958 :     $smlnj-tdp/coverage.cm
1959 :     -- when loaded causes the coverage plugin to be installed

1975 :     Description:
1976 :    
1977 :     * Test coverage tool added!
1978 :     * Further reorganization of tracing-, debugging-, and profiling support:
1979 :    
1980 :     - moved original BTImp -- now called BackTrace -- into a separate
1981 :     library called $/trace-debug-profile.cm
1982 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
1983 :     - only the instrumentation mechanism is now left in the compiler proper
1984 :     - BackTrace module is a plugin which is NOT plugged in by default
1985 :     - Coverage module is another such plugin
1986 :    
1987 :     To get the benefits of any of these plugin modules, the code in
1988 :     question must be compiled with tdp instrumentation turned on. This
1989 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
1990 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1991 :    
1992 :     Plugins are selected at link time. (Pre-compiled instrumented code
1993 :     can be re-loaded with different plugins in effect.) When an
1994 :     instrumented module is linked, whatever plugins are at that time
1995 :     enabled will come into effect for that module.
1996 :    
1997 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
1998 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
1999 :     To enable the coverage plugin, load the same library and invoke
2000 :     Coverage.install().
2001 :    
2002 :     Back-traces are generated automatically on uncaught exceptions and
2003 :     when the code in question explicitly invokes BackTrace.trigger().
2004 :    
2005 :     Coverage (and execution frequency-) information must be queried
2006 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2086 :     carries a FNexp as part of the type definition. This eliminates some
2087 :     superfluous sanity checks at runtime down the road.
2088 :    
2089 :     Some minor cleanup of the btrace code.

2095 :     Description:
2096 :    
2097 :     Added hack to make slave mode work in the presence of the version
2098 :     tool. (Still, since the master does two passes over the code for
2099 :     CMB.make, the release number gets bumped twice when slaves are
2100 :     attached. I don't know if this is worth fixing...)

2106 :     Description:
2107 :    
2108 :     * Moved the "version" magic into its own little library under
2109 : mblume 1672 src/system/smlnj/internal. This avoids expensive reconstruction of
2110 :     a stable src/compiler/core.cm.
2111 : mblume 1639
2112 : mblume 1672 * At the same time, structure CompilerVersion is now known as
2113 :     structure SMLNJVersion.
2114 : mblume 1639
2115 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2116 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2117 :     Also, loading the versiontool does not work when rebuilding the system
2118 :     because CM is not properly initialized at that time.

2123 :     Tag: blume-20040929-autoversion
2124 :     Description:
2125 :    
2126 :     Implemented some CM magic to have
2127 :     file src/compiler/TopLevel/main/version.sml
2128 :     generated automagically.
2129 :     The version is taken from two files: config/version and config/release.
2130 :     The first is expected to contain a two-part version number such as 110.49.
2131 :     The second should contain a single number, but it may be missing.
2132 :    
2133 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2134 :     time the version tool is loaded (which is the first time you say CMB.make),
2135 :     then the tool will increment the value stored in config/release every
2136 :     time CMB.make is invoked.
2137 :    
2138 :     The binfile format is now insensitive to anything beyond the first
2139 :     two components of a version number, so bumping the release does not render
2140 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2141 :     during development without invalidating existing binfiles.
2142 :    
2143 :     In any case, every CMB.make updates the date information in version.sml.
2144 :     (This is the date that is printed in the banner.)

2157 :     Tag: blume-20040927-controls
2158 :     Description:
2159 :    
2160 :     Added two pieces of functionality to the Controls interface:
2161 :    
2162 :     1. val save'restore: 'a control -> unit -> unit
2163 :    
2164 :     grabs the current value of the control in stage 1 and restores it
2165 :     in stage 2.
2166 :    
2167 :     2. val set' : 'a control * 'a -> unit -> unit
2168 :    
2169 :     stores the given value into the control in stage 2 (i.e., delayed)
2170 :     but does all error checking in stage 1.
2171 :     (This is for string controls that need to do parse their argument --
2172 :     something that might fail. In some cases, notably in CM, one
2173 :     already knows the intended argument but wants to delay the actual
2174 :     assignment until a time when error recovery would be more difficult.)
2175 :    
2176 :     Changed the handling of controls in tool arguments to classes "sml" and
2177 :     "lazysml":
2178 :     - use Controls.save'restore as a more robust way of restoring the
2179 :     old value (in particular: without having to re-parse the string)
2180 :     - use controls to handle the "overload" keyword in the init group
2181 :     (I believe this change actually fixes a long-standing obscure bug.)

2186 :     Tag: blume-20040927-lazysml
2187 :     Description:
2188 :    
2189 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2190 :     difference to "sml" is that compilation is done with Control.lazysml
2191 :     set to true. A source of class "lazysml" is automatically recognized
2192 :     by a file name suffix of ".lml".
2193 :    
2194 :     In addition to the above feature, the original class "sml" now also
2195 :     supports a tool argument "lazy" which has the same effect. As a
2196 :     result, the following three lines are equivalent:
2197 :    
2198 :     foo.sml : lazysml
2199 :     foo.sml : sml (lazy)
2200 :     foo.sml (lazy)
2201 :    
2202 :     The setting goes into effect both during parsing and during
2203 :     compilation. The original setting is restored right after parsing and
2204 :     after compilation, respectively.
2205 :    
2206 :     In addition to all the above, there is also a general mechanism to set
2207 :     ANY of the "controls" that are available at the command line via
2208 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2209 :     apply as well. (In fact, "lazy" is implemented as a special case of
2210 :     the general mechanism.)
2211 :    
2212 :     The .cm file syntax uses a new keyword tool argument called "with".
2213 :     There are several ways of indicating the desired settings:
2214 :    
2215 :     foo.sml (with:parser.quotations=true)
2216 :     foo.sml (with:(name:parser.quotations value:true))
2217 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2218 :     foo.sml (with:(name1=value1 name2=value2 ...))
2219 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2220 :    
2221 :     etc.
2222 :    
2223 :     Another possible abbreviation is to leave out the =v or value:v part
2224 :     if the name refers to a boolean control (in which case the value is
2225 :     taken to be true). Thus, one could get lazy sml also by saying:
2226 :    
2227 :     foo.sml (with:parser.lazy-keyword=true)
2228 :     foo.sml (with:parser.lazy-keyword)
2229 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2230 :     foo.sml (with:(name:parser.lazy-keyword))

2480 :     (This is just for consistency.)
2481 :     - Started to produce what is supposed to become better (i.e., comprehensive)

2582 :     Description:
2583 :    
2584 :     Changed the interface of structures Timer and Unix to match the most
2585 :     recent Basis spec.
2586 :    
2587 :     In the case of Unix there still seems to be an open/weird issue:
2588 :    
2589 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2590 :     fresh streams whenever they are called -- as opposed to have them
2591 :     return the same stream every time. This design is supposed to
2592 :     prevent space leaks caused by proc values hanging on to streams.
2593 :    
2594 :     The reap function, on the other hand, is supposed to close the
2595 :     streams. This cannot be done without having a handle on the
2596 :     stream in proc after all...
2597 :    
2598 :     I took the liberty to implement the following stopgap solution:
2599 :    
2600 :     The proc value hangs on to the most recently created stream(s).
2601 :     Reap closes those. If either or both of the two streams hadn't
2602 :     been created at all yet, then reap will close the corresponding
2603 :     file descriptors directly.
2604 :    
2605 :     PS: I don't understand the original space leak argument anymore. If
2606 :     a proc hangs on to the imperative stream, then I/O operations on those
2607 :     will advance the state of the cached stream and avoid the space leak.

2620 :     Tag: blume-20040525-group-owner
2621 :     Description:
2622 :    
2623 :     CM now ignores (but still accepts) the "owner" information in group
2624 :     descriptions. The owner of a group is its next enclosing
2625 :     library. Each group must have a unique owner. (There is a virtual
2626 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2627 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2628 :     and CM would check that such a declaration is correct. The new scheme
2629 :     is to have CM check that for each group there is precisely one owning
2630 :     library.
2631 :    
2632 :     The advantage of the new scheme is that the programmer no longer needs
2633 :     to maintain the somewhat annoying owner information. The downside is
2634 :     that CM cannot enforce the ownership rule across multiple runs of
2635 :     CM.make. Fortunately, enclosing the same group in two different
2636 :     libraries A and B which are not part of the same program does not
2637 :     cause real problems.

2656 :     Description:
2657 :    
2658 :     Arranged for ml-build to clean up after itself a little bit better.
2659 :     The script generates a temporary SML source file and compiles it using
2660 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
2661 :     gets rid of those at the end, so they don't accumulate under .cm.
2662 :    
2663 :     This required a minor change to install.sh because the name of the

2665 :     installation time.

2684 :     for the voluminous patch!
2685 :    
2686 :     (I have not tested this patch under win32 yet.)
2687 :    
2688 : mblume 1490 Here is David's e-mail:
2689 :    
2690 :     Hi,
2691 :    
2692 :     Attached to this email you find a diff against sml/nj 110.45
2693 :     that will enable socket support under Windows.
2694 :    
2695 :     To apply the patch (using unix or cygwin)
2696 :     1) gunzip runtime.diff.gz
2697 :     2) "cd" into "src/runtime" in the source tree of a fresh
2698 :     110.45 installation.
2699 :     3) patch -p 1 < [your/path/to]runtime.diff
2700 :    
2701 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2702 :     I only ran a few tests for basic socket client functionality
2703 :     (which worked fine). Especially the functions that use ioctl
2704 : mblume 1490 are not tested at all and might not work (see below).
2705 :    
2706 :     I implemented this since we want to move to a newer version of sml/nj
2707 :     but need socket support in order to use it. This is the first time I
2708 :     even had a look at the sml/nj source, so please review my changes
2709 :     before making this part of the distribution! Here are a few issues
2710 : blume 2155 that I think might be better for someone to solve who is more
2711 : mblume 1490 familiar with the sml/nj source (and socket programming):
2712 :    
2713 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2714 :     exception since I could not figure out what the windows equivalent
2715 :     of these functions is
2716 :    
2717 :     - In sockets-osdep.h there are a some #include statements that are
2718 :     only used in a few files that include sockets-osdep.h
2719 :    
2720 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2721 :     does not process its return value since I don't know how to
2722 :     report an error upwards.
2723 :    
2724 :     - It would probably be good to have a call to WSACleanup() when
2725 : blume 2155 the library is unloaded (if there is such a possibility).
2726 : mblume 1490 Otherwise I think Windows will take care of this automatically
2727 :     when the process finishes.
2728 :    
2729 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2730 :     no idea if that is actually the proper replacement on Windows.
2731 :    
2732 :     - All these issues are marked in the code by "FIXME" comments.
2733 :    
2734 : blume 2155 We use sml/nj extensively in our products and are quite happy
2735 :     with it. I hope this contribution will help you.
2736 : mblume 1490
2737 :     Keep up the good work!

2902 :     Description:
2903 :    
2904 :     Eliminated the "dont_move_libraries" directive in config/targets.
2905 :     (The mechanism was broken and could not be fixed easily. Moreover,
2906 :     there does not seem to be any reason not to move all libraries into
2907 :     lib during installation. I originally implemented this directive as a
2908 :     backward-compatibility feature when I first introduced the new CM.
2909 :     Now that things have been stable for a long time and going back to the
2910 :     old CM is not an option, there is no reason to keep it around.)

2959 :     Tag: blume-20030926-ppautoload
2960 :     Description:
2961 :    
2962 :     I modified the read-eval-print loop so that the autoloader gets
2963 :     invoked whenever the prettyprinter tries to look up a symbol that
2964 :     is not currently defined in the toplevel environment but which
2965 :     appears in CM's autoload registry. As a result, we see far fewer of
2966 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
2967 :    
2968 :     In addition to this I tried to clean up some pieces of the Basis
2969 :     implementation (e.g., Socket, Word8Array) in order to prevent other
2970 :     instances of these ?.Foo.Bar.xxx names from being printed.
2971 :    
2972 :     The mechanism that picks names for types still needs some work, though.
2973 :     (Right now it seems that if there is a type A.t which is defined to
2974 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
2975 :     "?.B.u" although the perhaps more sensible solution would be to use
2976 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
2977 :     a chain of DEFtycs not farther than there are corresponding toplevel
2978 :     names in the current environment.)

2984 :     Description:
2985 :    
2986 :     Another installer tweak: All the ML code for the installer is now
2987 :     compiled during CMB.make and put into a little library called
2988 :     $smlnj/installer.cm. The installation then simply invokes
2989 :    
2990 :     sml -m $smlnj/installer.cm
2991 :    
2992 :     and everything happens automagically.
2993 :    
2994 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
2995 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
2996 :     and BINDIR.
2997 :    
2998 :     The new scheme guarantees that the ML code responsible for the installation
2999 :     is in sync with the APIs of the main system. Also, the installer is
3000 :     somewhat faster because the installer script is precompiled.

3006 :     Description:
3007 :    
3008 :     Added a signature SYNCHRONOUS_SOCKET to basis.cm. This is like SOCKET
3009 :     but excludes all non-blocking operations. Defined SOCKET (in Basis)
3010 :     and CML_SOCKET in terms of SYNCHRONOUS_SOCKET. Removed superfluous
3011 :     implementations of non-blocking operations from CML's Socket
3012 :     structure.

3017 :     Tag: blume-20030924-sockets
3018 :     Description:
3019 :    
3020 :     1. Fixed SOCKET API and implementation to match Basis spec.
3021 :     This required changing the internal representation of sockets to one
3022 :     that remembers (for each socket file descriptor) whether it is currently
3023 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3024 :     call is made only if the state actually needs to change).
3025 :    
3026 :     2. OS-specific details of sockets were moved into separate files, thus
3027 :     making it possible to unify the bulk of the socket implementations
3028 :     between Unix and Win32.
3029 :    
3030 :     3. CML's socket API changed accordingly.
3031 :     (Note that we need to remove non-blocking functions from this API
3032 :     since they are redundant in the case of CML!)
3033 :    
3034 :     4. CML's socket implementation now makes use of non-blocking functions
3035 :     provided by Basis, thus removing all OS-dependent code from this part
3036 :     of CML.
3037 :    
3038 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3084 :

3151 :     Description:
3152 :    
3153 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3154 :     Modified config/install.bat to take advantage of it. Also modified
3155 :     config/install.sh (and called it config/new-install.sh) to take advantage
3156 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3157 :     independent.)
3158 :    
3159 :     The installer can now install everything under Win32
3160 :     as well as under *nix as long as it compiles.
3161 :    
3162 :     Other changes:
3163 :    
3164 :     - made CML compile again under Win32
3165 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3166 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3167 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3168 :     same as type int; under Win32 it isn't
3169 :     - fixed some slice-related problems in the win32-specific parts of CML
3170 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3171 :     (under Win32, the volume name is case-insensitive, and the
3172 :     OS.Path code compares volume names for equality)

3189 : mblume 1350 Description:
3190 :    
3191 :     1. Changed interface to vectors and arrays in Basis to match
3192 :     (draft) Basis spec.
3193 :     2. Added signatures and implementations of slices according to
3194 :     Basis spec.
3195 :     3. Edited source code throughout the system to make it compile again
3196 :     under 1. and 2. (In some cases code had to be added to have it
3197 :     match the new signatures.)
3198 :     4. MLRISC should be backward-compatible: the copies of the originals
3199 :     of files that needed to change under 3. were retained, the .cm files
3200 :     check the compiler version number and use old versions when
3201 :     appropriate.
3202 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3203 :     dirstream -> string option (in accordance with Basis spec).
3204 :     6. When generating code that counts lines, ml-lex used function
3205 :     CharVector.foldli, taking advantage of its old interface.
3206 :     This has been replaced with the corresponding code from
3207 :     CharVectorSlice. (html-lex must be re-lexed!)
3208 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3209 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3210 :     8. Removed temporary additions (fromInternal, toInternal) from the
3211 :     (now obsolete) IntInf in smlnj-lib/Util.
3212 :     9. Cleaned up structure Byte.
3213 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3214 :     Cleaned/corrected implementation of Date.
3215 :     (Still need to check for correctness; implement better canonicalizeDate.)
3216 :     11. Added "scan" to signature IEEE_REAL.
3217 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3218 :     mod and rem when second operand is 2 (for parity checks).]
3219 :     13. Changed representation of type Time.time, using a single IntInf.int
3220 :     value counting microseconds. This considerably simplified the
3221 :     implementation of structure Time. We now support negative time
3222 :     values; scan and fromString handle signs.
3223 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3224 :     ArraySlice).

3230 :     Description:
3231 :    
3232 :     This is a major update which comes with a version number bump
3233 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3234 :     and an implementation of IntInf in the Basis.
3235 :    
3236 :     There are a fairly large number of related changes and updates throughout
3237 :     the system:
3238 :    
3239 :     Basis:
3240 :     - Implemented IntInf.
3241 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3242 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3243 : mblume 1347 - Added FixedInt as a synonym for Int32.
3244 :    
3245 :     compiler:
3246 :     * Added support for a built-in intinf type.
3247 :     - literals
3248 :     - pattern matching
3249 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3250 :     - overloading on literals and operations
3251 :    
3252 :     This required adding a primitive type intinf, some additional
3253 :     primops, and implementations for several non-trivial intinf
3254 :     operations in Core. (The intinf type is completely abstract
3255 :     to the compiler; all operations get delegated back to the Core.)
3256 :    
3257 :     * Intinf equality is handled by polyequal. However, the compiler
3258 :     does not print its usual warning in this case (since polyequal
3259 :     is the right thing to do there).
3260 :    
3261 :     * Improved the organization of structure InlineT.
3262 :    
3263 :     * A word about conversion primops:
3264 :     If conversions involving intinf do not cancel out during
3265 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3266 : mblume 1347 Since all core access must be resolved already during the FLINT
3267 :     translate phase, it would be too late a the time of CPS contract
3268 : mblume 1348 to add new Core calls. For this reason, conversion primops
3269 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3270 :     they are supposed to convert, and 2. the Core function that
3271 :     can help with this conversion if necessary. If CPS contract
3272 : mblume 1348 eliminates a primop, then the associated Core function becomes
3273 :     dead and goes away. Intinf conversion primops that do not get
3274 :     eliminated by CPS contract get rewritten into calls of their
3275 :     core functions by a separate, new phase.
3276 : mblume 1347
3277 :     interactive system:
3278 :     - Control.Print.intinfDepth controls max length of intinf constants
3279 :     being printed. (Analogous to Control.Print.stringDepth.)
3280 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3281 :     duplicates; replaced some of the code with code that makes better
3282 :     use of library functionality.
3283 :    
3284 :     CM:
3285 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3286 :     are no longer silent.
3287 :    
3288 :     CKIT:
3289 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3290 :     in favor of LargeInt -- which is now the same as IntInf.
3291 :     CKIT-knowledgable people should check whether this is what's
3292 :     intended and otherwise change things back to using Int32 or
3293 :     FixedInt.
3294 :    
3295 :     Throughout the code:
3296 : mblume 1348 Started using IntInf.int literals and built-in operations
3297 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3316 :     Tag: blume-20030811-windows
3317 :     Description:
3318 :    
3319 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3320 :    
3321 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3322 :    
3323 :     This patch restores SML/NJ's ability to run under win32. There are a
3324 :     number of changes, including fixes for several bugs that had gone
3325 :     unnoticed until now:
3326 :    
3327 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3328 :     trying to run the win32 version from within cygwin.)
3329 :    
3330 :     - There are a number of simple .bat scripts that substitute for their
3331 :     corresponding Unix shell-scripts. (See below.)
3332 :    
3333 :     - The internals of ml-build have been modified slightly. The main
3334 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3335 :     using OS.Process.system, the ML process delegates this task back
3336 :     to the script. Otherwise problems arise in mixed environments such
3337 :     as Cygwin where scripts look and work like Unix scripts, but
3338 :     where OS.Process.system cannot run them.
3339 :    
3340 :     - In CM, the srcpath pickler used native pathname syntax -- which
3341 :     is incorrect in the case of cross-compilation. The new pickle format
3342 :     is independent of platform-specific naming conventions.
3343 :    
3344 :     - Path configuration files (such as lib/pathconfig) can now choose
3345 :     between native and standard syntax. Placing a line of the form
3346 :    
3347 :     standard!
3348 :    
3349 :     into the file causes all subsequent paths to be interpreted using
3350 :     CM standard pathname syntax (= Unix conventions); a line
3351 :    
3352 :     native!
3353 :    
3354 :     switches back to native style. This was needed so that
3355 :     path config files can be written portably, see src/system/pathconfig.
3356 :    
3357 :     - Runtime system:
3358 :    
3359 :     - win32-filesys.c: get_file_time and set_file_time now
3360 :     access modification time, not creation time.
3361 :    
3362 :     - I/O code made aware of new array representation.
3363 :    
3364 :     - Bug fixes in X86.prim.masm.
3365 :    
3366 :     - src/system/makeml made aware of win32. (For use under cygwin
3367 :     and other Unix-environments for windows.)
3368 :    
3369 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3370 :     which caused BinIO.inputAll to fail consistently.
3371 :    
3372 :     .bat scripts:
3373 :    
3374 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3375 :    
3376 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3377 :     applications (sml, ml-yacc, ml-lex).
3378 :     - ml-build.bat: analogous to ml-build.
3379 :     - config\install.bat: Analogous to config/install.sh. This requires
3380 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3381 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3382 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3383 :     and the bootfile hierarchy must have been unpacked under
3384 :     sml.boot.x86-win32.
3385 :     The script is very primitive and does a poor job at error checking.
3386 :     It only installs the base system, ml-lex, and ml-yacc. No other
3387 :     libraries are being installed (i.e., you get only those that
3388 :     are part of the compiler.)
3389 :     - link-sml.bat: analogous to .link-sml, but not currently used
3390 :    
3391 :     Unrelated bug fixes:
3392 :    
3393 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3394 :     types.
3395 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3396 :     otherwise.)

3420 :     Description:
3421 :    
3422 :     Two changes:
3423 :    
3424 :     1. Added a flag for controlling whether non-exhaustive bindings will
3425 :     be treated as errors (default is false).
3426 :     2. Cleaned up the *entire* source tree so that CMB.make goes through

3433 :     Description:
3434 :    
3435 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3436 :    
3437 :     This mainly affects the quality of error messages. However, some
3438 :     of the code is now more straightforward than before. (Treatment of
3439 :     the above four constructs in translate.sml is much simpler than
3440 :     the "macro-expansion" that was going on before. Plus, the mach-
3441 :     compiler no longer gets invoked just to be able to compile an
3442 :     if-expression.)
3443 :    
3444 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3445 :     interactive loop.

3452 :    
3453 : blume 2155 Ported the runtime system to cygwin, which uses the unix

3455 :    
3456 : blume 2155 o getnetbyname, getnetbyaddr: these functions seem to be missing in
3457 : allenleung 1327 the Cygwin library.
3458 :     o Ctrl-C handling may be flaky.
3459 :     o Windows system calls and Windows I/O are not supported.
3460 :    
3461 :     A new set of binfiles is located at:
3462 :    
3463 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3464 :    
3465 :     This is only needed for bootstrapping the cygwin version of smlnj.

3677 :     Description:
3678 :    
3679 :     - John tweaked runtime to be silent on heap export (except when
3680 :     GC messages are on).
3681 :     - I added a few more things (cross-compiling versions of CMB) to
3682 :     config/preloads (as suggestions).

3687 :     Tag: blume-20020520-controls
3688 :     Description:
3689 :    
3690 :     - Added ControlUtil structure to control-lib.cm.
3691 :     - Use it throughout.
3692 :     - Used Controls facility to define MLRISC controls (as opposed to
3693 :     registering MLRISC control ref cells with Controls after the fact)
3694 :     - Fixed messed-up controls priorities.
3695 :    
3696 :     * Removed again all the stuff from config/preloads that one wouldn't
3697 :     be able to preload at the time the initial heap image is built.
3698 :     (Many libraries, e.g., CML, do not exist yet at this time. The
3699 :     only libraries that can be preloaded via config/preloads are those
3700 :     that come bundled with the bootfiles.)

3715 :     Description:
3716 :    
3717 :     o Made the mdl tool stuff compile and run again.
3718 :     o I've disabled all the stuff that depends on RTL specifications; they
3719 :     are all badly broken anyway.

3725 :     Description:
3726 :    
3727 :     0. John Reppy made several modifications to the SML/NJ library.
3728 :     In particular, there is a shiny new controls-lib.cm.
3729 :    
3730 :     1. Pushed new controls interface through compiler so that everything
3731 :     compiles again.
3732 :    
3733 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3734 :     SML/NJ library (so that CML compiles again).
3735 :    
3736 :     3. Modified init scripts because XXX_DEFAULT environment variables
3737 :     are no longer with us. (Boot-time initialization is now done
3738 :     using the same environment variables that are also used for
3739 :     startup-time initialization of controls.)

3744 :     Tag: george-20020515-pseudo-op-decls
3745 :     Description:
3746 :    
3747 :     All pseudo-ops emitted before the first segment declaration
3748 :     such as TEXT, DATA, and BSS directives are assumed to be global
3749 :     declarations and are emitted first in the assembly file. This is
3750 :     useful in a number of situations where one has pseudo-ops that are not
3751 :     specific to any segment, and also works around the constraint that one
3752 :     cannot have client pseudo-ops in the TEXT segment.
3753 :    
3754 :     Because no segment is associated with these declarations it is
3755 :     an error to allocate any space or objects before the first segment
3756 :     directive and an exception will be raised. However, we cannot make
3757 :     this check for client pseudo-ops.
3758 :    
3759 :     These top level declarations are a field in the CFG graph_info.
3760 :     In theory you can continue to add to this field after the CFG has been
3761 :     built -- provided you know what you are doing;-)

3766 :     Tag: blume-20020513-pp-etc
3767 :     Description:
3768 :    
3769 :     A few minor bugfixes:
3770 :    
3771 :     - Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
3772 :     (Bogus printouts for redefined bindings still occur. Compiler
3773 :     bug should no longer occur now. We need to redo the prettyprinter
3774 :     from scratch.)
3775 :    
3776 :     - CM pathname printer now also adds escape sequences for ( and )
3777 :    
3778 :     - commend and docu fixes for ml-nlffi

3783 :     Tag: blume-20020510-erg-textio
3784 :     Description:
3785 :    
3786 :     Applied the following bugfix provided by Emden Gansner:
3787 :    
3788 :     Output is corrupted when outputSubstr is used rather than output.
3789 :    
3790 : blume 2155 The problem occurs when a substring
3791 : blume 1189
3792 :     ss = (s, dataStart, dataLen)
3793 :    
3794 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3795 :     avail bytes of s, starting at index dataStart, are copied into the
3796 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3797 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3798 :     starting this copy at index dataStart+avail in s, the current code
3799 : blume 1189 starts the copy at index avail.
3800 :    
3801 :     Fix:
3802 :     In text-io-fn.sml, change line 695 from
3803 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3804 : blume 2155 to
3805 : blume 1189 val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

3811 :     Description:
3812 :    
3813 :     1. Grabbed newer assyntax.h from the XFree86 project.
3814 :     2. Fiddled with how to compile X86.prim.asm without warnings.
3815 :     3. (Very) Minor cleanup in CM.

3820 :     Tag: blume-20020401-x86div
3821 :     Description:
3822 :    
3823 :     Added full support for div/mod/rem/quot on the x86, using the machine
3824 :     instruction's two results (without clumsily recomputing the remainder)
3825 :     directly where appropriate.
3826 :    
3827 :     Some more extensive power-of-two support was added to the x86 instruction
3828 :     selector (avoiding expensive divs, mods, and muls where they can be
3829 :     replaced with cheaper shifts and masks). However, this sort of thing
3830 :     ought to be done earlier, e.g., within the CPS optimizer so that
3831 :     all architectures benefit from it.
3832 :    
3833 :     The compiler compiles to a fixed point, but changes might be somewhat
3834 :     fragile nevertheless. Please, report any strange things that you might
3835 :     see wrt. div/mod/quot/rem...

3840 :     Tag: blume-20020329-div
3841 :     Description:
3842 :    
3843 :     Fixed my broken div/mod logic. Unfortunately, this means that the
3844 :     inline code for div/mod now has one more comparison than before.
3845 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3846 :     The problem was with quotient = 0, because that alone does not tell
3847 :     us which way the rounding went. One then has to look at whether
3848 :     remainder and divisor have the same sign... :(
3849 :    
3850 :     Anyway, I replaced the bootfiles with fresh ones...

3855 :     Tag: blume-20020329-inlprims
3856 :     Description:
3857 :    
3858 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
3859 :    
3860 :     Primops have changed. This means that the bin/boot-file formats have
3861 :     changed as well.
3862 :    
3863 :     To make sure that there is no confusion, I made a new version.
3864 :    
3865 :    
3866 :     CHANGES:
3867 :    
3868 :     * removed REMT from mltree (remainder should never overflow).
3869 :    
3870 :     * added primops to deal with divisions of all flavors to the frontend
3871 :    
3872 :     * handled these primops all the way through so they map to their respective
3873 :     MLRISC support
3874 :    
3875 :     * used these primops in the implementation of Int, Int32, Word, Word32
3876 :    
3877 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3878 :    
3879 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
3880 :    
3881 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3882 :     floating point
3883 :    
3884 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3885 :     and Real (but Real.abs maps to a separate floating-point-only primop)
3886 :    
3887 :    
3888 :     TODO items:
3889 :    
3890 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
3891 :     instructions because the machine instruction encoder cannot handle
3892 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
3893 :     REM in the first place, and REM is supported by the x86 machine coder.)
3894 :    
3895 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
3896 :     selection phase. (The two can be streamlined because the hardware
3897 :     delivers both quotient and remainder at the same time anyway.)
3898 :    
3899 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
3900 :     (Currently the behavior is inconsistent both across architectures and
3901 :     wrt. the draft Basis spec.)
3902 :    
3903 :     * Word8 should eventually be handled natively, too.
3904 :    
3905 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
3906 :     as if there currently is no execution path that could trigger it in
3907 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
3908 :     hold for things like multiplication and division.)

3913 :     Tag: blume-20020327-mlrisc-divisions
3914 :     Description:
3915 :    
3916 :     Added support for all four division operations (ML's div, mod, quot,
3917 :     and rem) to MLRISC. In the course of doing so, I also rationalized
3918 :     the naming (no more annoying switch-around of DIV and QUOT), by
3919 :     parameterizing the operation by div_rounding_mode (which can be either
3920 :     DIV_TO_ZERO or DIV_TO_NEGINF).
3921 :    
3922 :     The generic MLTreeGen functor takes care of compiling all four
3923 :     operations down to only round-to-zero div.
3924 :    
3925 :     Missing pieces:
3926 :    
3927 :     * Doing something smarter than relying on MLTreeGen on architectures
3928 :     like, e.g., the x86 where hardware division delivers both quotient and
3929 :     remainder at the same time. With this, the implementation of the
3930 :     round-to-neginf operations could be further streamlined.
3931 :    
3932 :     * Remove inlining support for div/mod/rem from the frontend and replace it
3933 :     with primops that get carried through to the backend. Do this for all
3934 :     int and word types.

3939 :     Tag: blume-20020325-divmod
3940 :     Description:
3941 :    
3942 :     I improved (hopefully without breaking them) the implementation of Int.div,
3943 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
3944 :     advantage of the following observations:
3945 :    
3946 :     Let q = x quot y r = x rem y
3947 :     d = x div y m = x mod y
3948 :    
3949 :     where "quot" is the round-to-zero version of integer division that
3950 :     hardware usually provides. Then we have:
3951 :    
3952 :     r = x - q * y where neither the * nor the - will overflow
3953 :     d = if q >= 0 orelse x = q * y then q else q - 1
3954 :     where neither the * nor the - will overflow
3955 :     m = if q >= 0 orelse r = 0 then r else r + y
3956 :     where the + will not overflow
3957 :    
3958 :     This results in substantial simplification of the generated code.
3959 :     The following table shows the number of CFG nodes and edges generated
3960 :     for
3961 :     fun f (x, y) = x OPER y
3962 :     (* with OPER \in div, mod, quot, rem *)
3963 :    
3964 :    
3965 :     OPER | nodes(old) | edges(old) | nodes(new) | edges(new)
3966 :     --------------------------------------------------------
3967 :     div | 24 | 39 | 12 | 16
3968 :     mod | 41 | 71 | 12 | 16
3969 :     quot | 8 | 10 | 8 | 10
3970 :     rem | 10 | 14 | 8 | 10

4003 :     Description:
4004 :    
4005 :     1. Changes to FLINT primops:
4006 :    
4007 :     (* make a call to a C-function;
4008 :     * The primop carries C function prototype information and specifies
4009 :     * which of its (ML-) arguments are floating point. C prototype
4010 :     * information is for use by the backend, ML information is for
4011 :     * use by the CPS converter. *)
4012 :     | RAW_CCALL of { c_proto: CTypes.c_proto,
4013 :     ml_args: ccall_type list,
4014 :     ml_res_opt: ccall_type option,
4015 :     reentrant : bool
4016 :     } option
4017 :     (* Allocate uninitialized storage on the heap.
4018 :     * The record is meant to hold short-lived C objects, i.e., they
4019 : blume 2155 * are not ML pointers. With the tag, the representation is
4020 : leunga 1174 * the same as RECORD with tag tag_raw32 (sz=4), or tag_fblock (sz=8)
4021 :     *)
4022 : blume 2155 | RAW_RECORD of {tag:bool,sz:int}
4023 : leunga 1174 and ccall_type = CCALL_INT32 | CCALL_REAL64 | CCALL_ML_PTR
4024 :    
4025 :     2. These CPS primops are now overloaded:
4026 :    
4027 :     rawload of {kind:numkind}
4028 :     rawstore of {kind:numkind}
4029 :    
4030 :     The one argument form is:
4031 :    
4032 :     rawload {kind} address
4033 :    
4034 :     The two argument form is:
4035 : blume 2155
4036 : leunga 1174 rawload {kind} [ml object, byte-offset]
4037 :    
4038 :     3. RAW_CCALL/RCC now takes two extra arguments:
4039 :    
4040 :     a. The first is whether the C call is reentrant, i.e., whether
4041 :     ML state should be saved and restored.
4042 :     b. The second argument is a string argument specifying the name of
4043 :     library and the C function.
4044 :    
4045 :     These things are currently not handled in the code generator, yet.
4046 :    
4047 :     4. In CProto,
4048 :    
4049 : blume 2155 An encoding type of "bool" means "ml object" and is mapped into
4050 :     C prototype of PTR. Note that "bool" is different than "string",
4051 : leunga 1174 even though "string" is also mapped into PTR, because "bool"
4052 :     is assigned an CPS type of BOGt, while "string" is assigned INT32t.
4053 :    
4054 :     5. Pickler/unpicker
4055 :    
4056 :     Changed to handle RAW_RECORD and newest RAW_CCALL
4057 :    
4058 :     6. MLRiscGen,
4059 :    
4060 :     1. Changed to handle the new rawload/rawstore/rawrecord operators.
4061 :     2. Code for handling C Calls has been moved to a new module CPSCCalls,
4062 :     in the file CodeGen/cpscompile/cps-c-calls.sml
4063 :    
4064 :     7. Added the conditional move operator
4065 :    
4066 :     condmove of branch
4067 :    
4068 : blume 2155 to cps. Generation of this is still buggy so it is currently

4081 : george 1168 ---------------------
4082 :     See the file compiler/CodeGen/cpscompile/cpsBranchProb.sml.
4083 :    
4084 :     By design it uses the Dempster-Shafer theory for combining
4085 :     probabilities. For example, in the function:
4086 :    
4087 :     fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)
4088 :    
4089 :     the ball-larus heuristics predicts that the n=0 is unlikely
4090 :     (OH-heuristic), and the 'then' branch is unlikely because of the
4091 :     RH-heuristic -- giving the 'then' branch an even lower combined
4092 : george 1171 probability using the Dempster-Shafer theory.
4093 : george 1168
4094 :     Finally, John Reppy's loop analysis in MLRISC, further lowers the
4095 :     probability of the 'then' branch because of the loop in the else
4096 :     branch.

4099 :     Graphical Viewing:
4100 : blume 2155 ------------------
4101 : george 1168 I merely plugged in Allen's graphical viewers into the compiler. The
4102 :     additional code is not much. At the top level, saying:
4103 :    
4104 :     Control.MLRISC.getFlag "cfg-graphical-view" := true;
4105 :    
4106 :     will display the graphical view of the control flow graph just before
4107 :     back-patching. daVinci must be in your path for this to work. If
4108 :     daVinci is not available, then the default viewer can be changed
4109 :     using:
4110 :    
4111 :     Control.MLRISC.getString "viewer"
4112 :    
4113 :     which can be set to "dot" or "vcg" for the corresponding viewers. Of
4114 :     course, these viewers must be in your path.
4115 :    
4116 :     The above will display the compilation unit at the level of clusters,
4117 :     many of which are small, boring, and un-interesting. Also setting:
4118 :    
4119 :     Control.MLRISC.getInt "cfg-graphical-view_size"
4120 :    
4121 :     will display clusters that are larger than the value set by the above.

4145 :     Description:
4146 :    
4147 : blume 2155 1. Recoded the buggy parts of x86-fp.
4148 : leunga 1156
4149 :     a. All the block reordering code has been removed.
4150 :     We now depend on the block placement phases to do this work.
4151 :    
4152 :     b. Critical edge splitting code has been simplified and moved into the
4153 :     CFG modules, as where they belong.
4154 :    
4155 :     Both of these were quite buggy and complex. The code is now much, much
4156 :     simpler.
4157 :    
4158 :     2. X86 backend.
4159 :    
4160 :     a. Added instructions for 64-bit support. Instruction selection for
4161 :     64-bit has not been committed, however, since that
4162 : blume 2155 requires changes to MLTREE which haven't been approved by
4163 : leunga 1156 Lal and John.
4164 :    
4165 : blume 2155 b. Added support for FUCOMI and FUCOMIP when generating code for
4166 : leunga 1156 PentiumPro and above. We only generate these instructions in
4167 :     the fast-fp mode.
4168 :    
4169 : blume 2155 c. Added cases for JP and JNP in X86FreqProps.
4170 :    
4171 : leunga 1156 3. CFG
4172 :    
4173 :     CFG now has a bunch of methods for edge splitting and merging.
4174 :    
4175 :     4. Machine description.
4176 :    
4177 :     John's simplification of MLTREE_BASIS.fcond broke a few machine
4178 :     description things:
4179 :    
4180 :     rtl-build.{sig,sml} and hppa.mdl fixed.
4181 :    
4182 : blume 2155 NOTE: the machine description stuff in the repository is still broken.
4183 :     Again, I can't put my fixes in because that involves
4184 :     changes to MLTREE.
