203 : blume 2692 Date: 2007/06/06 21:45:00 CDT
204 :     Description:
205 :    
206 :     - Aaron: fixed a number of bugs in ml-ulex.
207 :     - Matthias:
208 :     - added CM control "cm.force-tools"; this is false by default;
209 :     when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
210 :     will be forced to run regardless of whether or not their targets
211 :     are up-to-date
212 :     - changed installer code so that config/install.sh will re-build
213 :     heap images for all tools even if those heap images already existed
214 :    
215 :     ----------------------------------------------------------------------
216 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
217 : blume 2688 Date: 2007/06/04 21:21:00 CDT
218 :     Description:
219 :    
220 :     After Aaron Turon's bug fix for ml-ulex (handling the ^ character
221 :     in legacy mode), re-ran the lexer generator on all lex input files
222 :     and committed the results.
223 :    
224 :     This should fix the problem with ckit and nlffi that was reported
225 :     by Vesa A. Norrman.

236 : dbm 2650 Name: Dave MacQueen (dbm@cs.uchicago.edu)
237 :     Date: 2007/05/31 14:55:00 CDT
238 :     Revision: 2650
239 :     Description:
240 :    
241 :     3rd merge of base from primop-branch-3 into the trunk.
242 :     Additional bug fixes included:
243 :    
244 :     * Timer.cpu_timer, etc. type printing corrected (by making
245 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
246 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
247 :     Stefan Monnier)
248 :    
249 :     ----------------------------------------------------------------------
250 : blume 2645 Name: Matthias Blume (http://www.tti-c.org/blume/)
251 :     Date: 2007/05/31 11:40:00 CDT
252 :     Description:
253 :    
254 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
255 :    
256 :     Also, changed the handling of "no core access": When translate.sml
257 :     needs access to a core exception at a time when the core has not
258 :     been set up yet (this only happens when compiling system/smlnj/init/*),
259 :     then don't bother generating the corresponding tests.
260 :    
261 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
262 :     the exception. Unfortunately, that confuses the plambda type checker.
263 :     Moreover, it does not do any good, because at runtime we don't expect
264 :     such an exception to be ever raised. (The code in system/smlnj/init/*
265 :     has to be written very carefully with this in mind!)

268 : mrainey 2639 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
269 :     Date: 2007/05/29
270 :     Description:
271 :    
272 :     Added FSQRT instructions for the AMD64 code generator.
273 :    
274 :     ----------------------------------------------------------------------
275 : blume 2626 Name: Matthias Blume (http://www.tti-c.org/blume/)
276 :     Date: 2007/05/29 19:00:00 CDT
277 :     Description:
278 :    
279 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
280 :     with an explicit test for zero division. This should fixes several
281 :     regressions and makes it possible for downstream optimization phases
282 :     to treat these operations as "pure" when they are applied to unsigned
283 :     operands.
284 :    
285 :     ----------------------------------------------------------------------
286 : mrainey 2622 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
287 :     Date: 2007/05/29
288 :     Description:
289 :    
290 :     Added the new MLRISC code generator for the AMD64. This version,
291 :     in contrast to the previous one, uses SSE registers and instructions
292 :     for all floating-point computations.
293 :

295 : jhr 2613 Name: John Reppy (http://www.cs.uchicago.edu/~jhr)
296 : jhr 2617 Date: 2007/05/29
297 : jhr 2613 Description:
298 :    
299 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
300 :     for bugs #1415 and #1416. We also now correctly handle format characters that
301 :     lie outside the specified set.

304 : blume 2610 Name: Matthias Blume (http://www.tti-c.org/blume/)
305 :     Date: 2007/05/23 22:30:00 CDT
306 :     Description:
307 :    
308 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
309 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
310 :    
311 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
312 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
313 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
314 :     while running CMB.make. The point is that the single symbol
315 :     NO_PLUGINS is definde in all three cases.)
316 :    
317 :     I changed the three locations within the sources that get compiled
318 :     during CMB.make where ml-yacc or ml-lex input is processed: When
319 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
320 :     is bypassed.
321 :    
322 :     When bootstrapping new versions of the compiler, there can be
323 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
324 :     are not available or otherwise not operational. In this case one can
325 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
326 :     do so, the following command should be issued at the interactive
327 :     prompt:
328 :    
329 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
330 :    
331 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
332 :     files that normally would be generated by ml-yacc and ml-lex.
333 :     (Copies of these files are in the repository.)

336 : dbm 2603 Name: David MacQueen (dbm@cs.uchicago.edu)
337 :     Date: 2007/5/23 17:23:00 CDT
338 :     Revision: 2603
339 :     Description:
340 :    
341 :     2nd merge of base from primop-branch-3 into the trunk.
342 :     Additional bug fixes included:
343 :     Date.scan and Date.fromString fixed;
344 :     Overloading resolution fixed and some type printing problems corrected.

347 : blume 2578 Name: Matthias Blume (http://www.tti-c.org/blume/)
348 : blume 2589 Date: 2007/05/23 09:50:00 CDT
349 :     Description:
350 :    
351 :     Changed the installation mechanism for CM tool plugins. These are
352 :     just libaries and now get installed like ordinary libaries.
353 :    
354 :     There are now a number of new installation targets that give some
355 :     fine-grain control over what classes and suffixes are known, and what
356 :     they will map to.
357 :     See config/targets for details.
358 :    
359 :     The code that caused plugin installation as part of running a
360 :     tool's "build" script has been removed. (The build script is for
361 :     building, not for installing.)
362 :    
363 :     ----------------------------------------------------------------------
364 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
365 : blume 2578 Date: 2007/05/22 11:50:00 CDT
366 :     Description:
367 :    
368 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
369 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
370 :     CM fail if a shell tool reports a non-success exit status. If
371 :     the control is set to true, then CM will press on after tool failures
372 :     in the event that the target files exist (even though they are
373 :     considered outdated). Turning the control to true can be useful for
374 :     bootstrapping.

377 : adrassi 2570 Name: Aaron Turon (http://www.cs.uchicago.edu/~adrassi)
378 :     Date: 2007/05/19
379 :     Description:
380 :    
381 :     Merge of ml-lpt revisions for 110.64.
382 :    
383 :     The name of several ml-lpt-lib modules has changed:
384 :     Repair => AntlrRepair
385 :     StreamPos => AntlrStreamPos
386 :     ErrHandlerFn => AntlrErrHandler
387 :     EBNF => AntlrEBNF
388 :    
389 :     The ml-antlr specification format has changed: declarations such as
390 :     %tokens and nonterminal definitions can occur *multiple* times in the
391 :     same specification. The semantics are such that each new declaration
392 :     extends the previous ones. This does not apply to %start or %name,
393 :     of course.
394 :    
395 :     Importing a grammar via %import now includes *all* declarations in from
396 :     the imported grammar, except for %name, %entry, and %start. Tokens
397 :     and nonterminals can be dropped using the new %dropping clause of the
398 :     %import directive; the separate %drop and %extend have been removed.
399 :    
400 :     We now allow optional type annotations on nonterminals, using the %nonterms
401 :     directive as in ml-yacc.
402 :    
403 :     The refcell construct is now implemented using SML's regular reference
404 :     cells, so the :== and !! notation has been deprecated.
405 :    
406 :     The ml-antlr tool now does much more checking of specifications, and
407 :     its error messages have been greatly improved. Error repair for
408 :     generated parsers has been completely rewritten, and is now both
409 :     much faster and more accurate.
410 :    
411 :     ml-ulex is now more lenient with escape codes (non-SML-standard
412 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
413 :     Also, character classes may now include a "-" character at the beginning
414 :     as is standard in most other regexp tools.
415 :    
416 :     All of these changes are documented in the user guide, which has
417 :     been updated and improved with this merge.

420 : dbm 2492 Name: David MacQueen (http://www.cs.uchicago.edu/~jhr)
421 :     Date: 2007/05/03
422 :     Revision: r2492
423 :     Description:
424 :    
425 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
426 :     Significant changes in FLINT and the front end, mostly having to do
427 :     with a reorganized system for handling primops. Various bug fixes
428 :     and improvements in printing signatures.

432 :     Date: 2007/05/02
433 :     Description:
434 :    
435 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
436 :     The ml-antlr specification format has changed: declarations such as
437 :     %tokens and nonterminal definitions can occur *multiple* times in the
438 :     same specification. The semantics are such that each new declaration
439 :     extends the previous ones. Grammar extension constructs have also
440 :     changed. We now allow type annotations on nonterminals. Finally,
441 :     the refcell construct is now implemented using SML's regular reference
442 :     cells, so the :== and !! notation has been deprecated. All of these
443 :     changes will appear in the 110.64 user guide for ml-lpt.
444 :    
445 :     The ml-antlr tool now does much more checking of specifications, and
446 :     its error messages have been greatly improved. There has also been
447 :     some work on the error repair process for generated parsers, but this
448 :     will be further improved in 110.64.

453 :     Revision: r2492
454 :     Description:
455 :    
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
458 :     with a reorganized system for handling primops. Various bug fixes
459 :     and improvements in printing signatures.

485 :    
486 :     More Basis fixes: The Char.fromString (etc.) functions did not handle
487 :     the "\uxxxx" escape sequence. There is still an outstanding bug with
488 :     String.fromString the tail is a format escape. I added a comment to

567 :     Date: 2007/02/26
568 :     Description:
569 :    
570 :     Added preliminary support in MLRISC for Staged Allocation, a technique
571 :     for specifying calling conventions (see
572 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
573 :     Initially, we plan to use this code to generate C calls for the AMD64.
574 :    
575 :     The staged allocation code base resides in MLRISC/staged-allocation,
576 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

582 :    
583 :     Bug fix: when SaveCState was called with two values to save, a subsequent
584 :     GC could cause the RestoreCState to fail because the saved state had been
585 :     promoted to tagless pair.

596 :    
597 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
598 :     of the range -128 ... 127. I've changed the code so that the range
599 :     check is disabled. Only the low order 8 bits of the immediate operand

640 :     Date: 2007/01/31
641 :     Description:
642 :    
643 :     Brought ml-lpt manual up-to-date with the code. Many minor
644 :     improvements to the tools, and a few minor bugfixes. Prepared
645 :     ml-lpt-lib for integration with new UTF8 structure. Changed
646 :     the interface for creating streams in ml-ulex (we now support
647 :     stream creation from several kinds of sources). Overall, the
648 :     tools are now quite stable, and their interfaces are unlikely to
649 :     change in a way that would break compatibility. More work,
650 :     however, is needed in the documentation.

655 :     Description:
656 :    
657 :     Implemented library installer. Moved CM plugin code for
658 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
659 :     their respective trees. Implemented CM plugin for ml-ulex
660 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
661 :     and ml-antlr.
662 :    
663 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
664 :     CM tools. (It turns out to be too messy to do otherwise because
665 :     there is too much code that during installation relies on the presence
666 :     of these tools -- resulting in a tricky ordering problem.)

671 :     Description:
672 :    
673 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
674 :     Modified CM's startup code to use shiftArgs as it processes
675 :     command line arguments. This way, the init code in each .sml-file
676 :     or library that is mentioned at the top level will see only
677 :     those arguments that have not yet been processed at this point.
678 :     In other words, the init code can "seize control" and process the
679 :     remaining command line.

693 :    
694 :     Added the UTF8 structure and signature from the Moby compiler to
695 :     the SML/NJ library (and the CML library). These modules will replace
696 :     the version in the ml-lpt-lib.

736 :    
737 :     Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to
738 :     get the c_cc termios data copied correctly. Also moved the allocation
739 :     of the string to avoid problems if it caused a GC.

745 :     Date: 2006/12/08 09:50:00 CST
746 :     Description:
747 :    
748 :     Added code to CM's "standard shell tool" implementation which
749 :     causes it to tolerate (with a warning) the situation where the shell
750 :     command fails (e.g., due to the shell command's non-existence)
751 :     as long as all target files exist.
752 :    
753 :     This makes it possible to, e.g., build ml-yacc from sources even if
754 :     svn checkout messed up the time stamps on files in such a way that
755 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
756 :     be needed to re-process yacc.grm, but obviously it might not yet be
757 :     available at that time.)

763 :    
764 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
765 :     recvVecFromNB' in the SOCKET signature. This error is actually
766 :     in the SML Basis specification too.

783 :     to suppress them.

797 :     Description:
798 :    
799 :     New working release (110.60). NEW BOOTFILES!
800 :    
801 :     This is the first subversion-hosted release. There are also changes
802 :     to the directory layout. Here is a table:
803 :    
804 :     (All pathnames are relative to the SML/NJ "root" directory.)
805 :    
806 :     config -> config
807 :    
808 :     src/cm -> base/cm
809 :     src/compiler -> base/compiler
810 :     src/runtime -> base/runtime
811 :     src/system -> base/system
812 :    
813 :     src/cm/pgraph -> pgraph
814 :    
815 :     src/READMES -> base/READMES
816 :     src/$notefile -> base/NOTES/$notefile
817 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
818 :     MACOSXINSTALL WININSTALL
819 :    
820 :     src/smlnj-lib -> smlnj-lib
821 :     src/MLRISC -> MLRISC
822 :     ckit -> ckit
823 :     src/cml -> cml
824 :     src/eXene -> eXene
825 :     src/heap2asm -> heap2asm
826 :     src/lexgen -> lexgen
827 :     src/ml-burg -> ml-burg
828 :     src/ml-lex -> ml-lex
829 :     src/ml-yacc -> ml-yacc
830 :     src/ml-nlffi-lib -> nlffi/lib
831 :     src/ml-nlffigen -> nlffi/gen
832 :     src/smlnj-c -> smlnj-c
833 :     src/tools/TraceDebugProf -> trace-debug-profile
834 :    
835 :     In addition, there is also a new
836 :    
837 :     ml-lpt
838 :    
839 :     directory containing two new program generator tools: ml-ulex and
840 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
841 :     LL(k) parser generator). These tools are currently "beta-quality"
842 :    
843 :     The latest versios of the sources can now be obtained anonymously
844 :     via subversion. For this, it is useful to first check out
845 :    
846 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
847 :    
848 :     and put the resulting directory on your shell's PATH. This provides
849 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
850 :     and refresh-all.sh.
851 :    
852 :     To create a freshly checked-out copy of the sources, do
853 :    
854 :     checkout-all.sh [dir]
855 :    
856 :     where dir is the optional SML/NJ root directory (default is ".").
857 :    
858 :     This creates the above directory layout. Each subdirectory of
859 :     the root is under individual subversion control. The stat-all.sh
860 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
861 :     each of these subtrees.

866 :     Description:
867 :    
868 :     Reorganized directory layout.
869 :    
870 :     This is a temporary solution, more reorganization is to come.
871 :    
872 :     The basic idea is to have a number of toplevel trees, each corresponding
873 :     to a well-defined part of the overall system. Each part can be
874 :     maintained individually, even in separate source repositories,
875 :     although currently we still serve everything out of the main
876 :     smlnj-gforge tree.
877 :    
878 :     Installer and and scripts have been updated to reflect the new
879 :     layout. The installer (base/src/system/smlnj/installer) is now
880 :     "scriptable" to avoid burning too much knowledge about the
881 :     layout into SML source code. The main script used by the installer
882 :     is in config/actions.
883 :    
884 :     The main change is that many of the subdirectories of what used to
885 :     be known as "src" have moved to the toplevel. The "src" directory
886 :     itself has moved down into a subtree called "base". (We may eventually
887 :     get rid of the extra level of indirection represented by "src".)
888 :    
889 :     The layout is now as follows:
890 :    
891 :     toplevel tree name | default repository
892 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
893 :     -------------------+----------------------------------------------------
894 :     config | $gf/config/trunk
895 :     |
896 :     base | $gf/sml/trunk
897 :     |
898 :     smlnj-lib | $gf/smlnj-lib/trunk
899 :     MLRISC | $gf/MLRISC/trunk
900 :     |
901 :     ml-yacc | $gf/ml-yacc/trunk
902 :     ml-lex | $gf/ml-lex/trunk
903 :     ml-burg | $gf/ml-burg/trunk
904 :     lexgen | $gf/lexgen/trunk
905 :     heap2asm | $gf/heap2asm/trunk
906 :     |
907 :     cml | $gf/cml/trunk
908 :     eXene | $gf/eXene/trunk
909 :     ckit | $gf/ckit/trunk
910 :     nlffi | $gf/nlffi/trunk
911 :     |
912 :     smlnj-c | $gf/smlnj-c/trunk
913 :    
914 :     In $gf/admin there are a few useful shell scripts for checking out
915 :     and maintaining the entire collection of trees:
916 :    
917 :     admin/checkout-all.sh [dir]
918 :     -- optionally creates dir and checks out all trees from their
919 :     default repositories; if dir is missing, checkout into .
920 :     admin/refresh-all.sh [dir]
921 :     -- looks at all trees (from the above list) in dir (default: .)
922 :     and runs "svn update" if the tree exists and is under
923 :     subversion control;
924 :     non-existing or non-subversion trees are skipped
925 :     admin/stat-all.sh [dir]
926 :     -- like refresh-all.sh, but runs "svn stat" instead

1073 :    
1074 :     Hooked code for Darwin-specific Intel ABI into main compiler.
1075 :     (This is a temporary solution which relies on the fact that the
1076 :     compiler itself does not use NLFFI. Eventually we need to divorce

1106 :     Description:
1107 :    
1108 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1109 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1110 : blume 2155 at the time when config/preloads is processed, the library has to
1111 : mblume 1878 be referred to by another name. In 110.57 this would be
1112 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1113 :     to be valid as well.)

1169 :     Description:
1170 :    
1171 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1172 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1173 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1174 :     it. Instead, it has the status of "user code", so it should use
1175 :     $/basis.cm to refer to the Basis library. (At least that's true for
1176 :     the purpose of bootstrapping the previous change. In the future it
1177 :     might make sense to have versiontool.cm refer to
1178 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1179 :     compiler itself uses.)
1180 :    
1181 :     Also patched src/system/testml to have it activate those extra anchor
1182 :     bindings in config/extrapathconfig.

1187 :     Tag: blume-22051115-libraries
1188 :     Description:
1189 :    
1190 :     This change affects the way the following libraries are tied into
1191 :     the system:
1192 :    
1193 :     $/basis.cm
1194 :     $/smlnj-lib.cm
1195 :     $/pp-lib.cm
1196 :     $/controls-lib.cm
1197 :     $/html-lib.cm
1198 :     $/ml-yacc-lib.cm
1199 :    
1200 :     These libraries are now internally (as seen from the source code
1201 :     of the implementation itself) known by the following names:
1202 :    
1203 :     $smlnj/basis/basis.cm
1204 :     $smlnj/smlnj-lib/smlnj-lib.cm
1205 :     $smlnj/smlnj-lib/pp-lib.cm
1206 :     $smlnj/smlnj-lib/controls-lib.cm
1207 :     $smlnj/smlnj-lib/html-lib.cm
1208 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1209 :    
1210 :     This makes it possible to work with code that requires different
1211 :     versions of these libraries, and which refers to these libraries using
1212 :     their "default" names (i.e., the first set of names above). In other
1213 :     words, one can un-define or re-define those default names without
1214 :     compromising the proper functioning of the compiler itself.
1215 :    
1216 :     A similar procedure had already been performed for several of the
1217 :     MLRISC libraries that are linked into the compiler. I did some
1218 :     cleanup on this code.
1219 :    
1220 :     A new file in the config directory (named extrapathconfig) is
1221 :     responsible for setting up path anchors that the compiler itself does
1222 :     not need, but that are typically required by user code.

1401 :     Tag: blume-20050516-redump-heap
1402 :     Description:
1403 :    
1404 :     Added mechanism for re-creating a heap file for the interactive system
1405 :     after configuration variables have been changed.
1406 :    
1407 :     CM.redump_heap : string -> unit
1408 :    
1409 :     This is much like SMLofNJ.exportML, but starting from the resulting
1410 : blume 2155 heap does not return to the caller of CM.redump_heap but
1411 : mblume 1792 restarts the interactive system from scratch. The original call of
1412 :     CM.redump_heap does not return but ends the interactive session.
1413 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1414 :    
1415 :     Internally, redump_heap winds the dynamic execution context back to
1416 :     the point where the original heap image was created and re-executes
1417 :     the heap image generation code in the boot code.

1533 :     Tag: blume-20050114-heap2exec
1534 :     Description:
1535 :    
1536 :     Implemented new (but still experimental) heap2exec facility. This is
1537 :     tested under Mac OS X and should work under Linux (will test shortly).
1538 :     It will probably also work on the Sparc (will test some time later).
1539 :    
1540 :     - removed old "HACKED_STANDALONE" hack from runtime
1541 :    
1542 :     To be able to test this, uncomment the request for "heap2asm" in
1543 :     config/targets prior to installation. (Notice that this is different
1544 :     from "heap2exec" mentioned below. Not a typo.)
1545 :    
1546 :     To perform an actual test, run the command
1547 :    
1548 :     $ bin/heap2exec heapfile execfile
1549 :    
1550 :     (You can put heap2exec on your shell's path.)
1551 :    
1552 :     For example, run
1553 :    
1554 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1555 :    
1556 :     This will create a standalone executable called "mly" which you can
1557 :     then invoke directly as a command.

1584 :    
1585 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1586 :     (On the Mac, it is big-endian. And that's currently our only

1684 :    
1685 :     Added function HashString.hashString' for substrings.
1686 :     Hand-inlined CharVector.foldl into HashString (for speed).
1687 :     Modified implementation of structure Atom to avoid extracting
1688 :     strings from substrings unless necessary.

1702 :     Tag: blume-20041124-position
1703 :     Description:
1704 :    
1705 :     The compiler can now be compiled in a mode that makes structure Position
1706 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1707 :     for the time being.
1708 :    
1709 :     To enable 64-bit positions, use the following procedure:
1710 :    
1711 :     1. Start sml
1712 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1713 :     3. Type
1714 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1715 :     4. Run CMB.make() as usual.
1716 :    
1717 :     This is barely tested. The only test so far was a little SML program
1718 :     counting the number of characters in an 8-gigabyte file by
1719 :     reading it character-by-character. That test was successful.
1720 :    
1721 :     In support of 64-bit positions, a number of new functions have been
1722 :     added to the runtime system.

1763 :     Description:
1764 :    
1765 :     - Stripped down the versiontool: It now only handles the version number.
1766 :     The date string is generated at bootstrap time (during makeml).
1767 :    
1768 :     - In a previous commit, fixed a minor issue with how polyequal is being
1769 :     translated. In particular, the code now "looks through" abstractions.
1770 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1771 :     more efficient code. Important examples for where this matters are
1772 :     the new int64 and word64 types.

1787 :     Description:
1788 :    
1789 :     All the pieces of Word64 are now there, with the exception of the
1790 :     conversions from and to LargeWord. (Eventually these need to be identities,
1791 :     but for the time being they don't even make sense because LargeWord is
1792 :     32-bit wide.)
1793 :    
1794 :     Also started to add similar support for Int64, but major pieces of that
1795 :     are still missing.

1800 :     Tag: blume-20041111-word64
1801 :     Description:
1802 :    
1803 :     Structure Word64 is now (almost) complete, word literals and patterns
1804 :     seem to work. There are a few odd pieces missing. In particular,
1805 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1806 :     at the moment.
1807 :    
1808 :     Making Word64 official would mean that LargeWord becomes Word64. But
1809 :     this requires extreme care because most word-word conversions have to
1810 :     go through LargeWord, so making a mistake means loss of efficiency or
1811 :     worse. Eventually there will be a solution similar to (but actually
1812 :     simpler than) what I did with IntInf.

1841 :    
1842 :     Also:
1843 :    
1844 :     - Changend config/srcarchiveurl from a file just
1845 :     containing the URL string into a file containing
1846 :     shell script code. The code has access to the $VERSION variable.
1847 :     - Made corresponding changes to config/install.sh and config/unpack.
1848 :     - Default contents of config/srcarchiveurl uses $VERSION and
1849 :     normally does not have to be edited to reflect a version change.
1850 :    
1851 :     (As a result, a version change can be done by just editing
1852 :     config/version, the rest is now automatic.)

1892 :     Tag: blume-20041020-standalone-backtrace
1893 :     Description:
1894 :    
1895 :     Added a mechanism for getting back-trace information from standalone
1896 :     programs. Here is how it works:
1897 :    
1898 :     1. The part of the program from which you want to get backtrace
1899 :     information (usually the whole program) should be wrapped with
1900 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
1901 :     main program could be modified from something like
1902 :    
1903 :     fun main (pgm, args) = ...
1904 :    
1905 :     to
1906 :    
1907 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1908 :    
1909 :     2. To be able to access BackTrace.monitor, you have to add
1910 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
1911 :     main function.
1912 :    
1913 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1914 :     CM might have created in the past for your project).
1915 :    
1916 :     4. Build the system using this command line:
1917 :    
1918 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1919 :     myprog.cm MyProg.main myprog
1920 :    
1921 :     instead of the usual
1922 :    
1923 :     ml-build myprog.cm MyProg.main myprog
1924 :    
1925 :     I changed a library name:
1926 :    
1927 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1928 :    
1929 :     New libraries:
1930 :    
1931 :     $smlnj-tdp/back-trace.cm
1932 :     -- when loaded causes the back-trace plugin to be installed
1933 :     $smlnj-tdp/coverage.cm
1934 :     -- when loaded causes the coverage plugin to be installed

1950 :     Description:
1951 :    
1952 :     * Test coverage tool added!
1953 :     * Further reorganization of tracing-, debugging-, and profiling support:
1954 :    
1955 :     - moved original BTImp -- now called BackTrace -- into a separate
1956 :     library called $/trace-debug-profile.cm
1957 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
1958 :     - only the instrumentation mechanism is now left in the compiler proper
1959 :     - BackTrace module is a plugin which is NOT plugged in by default
1960 :     - Coverage module is another such plugin
1961 :    
1962 :     To get the benefits of any of these plugin modules, the code in
1963 :     question must be compiled with tdp instrumentation turned on. This
1964 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
1965 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1966 :    
1967 :     Plugins are selected at link time. (Pre-compiled instrumented code
1968 :     can be re-loaded with different plugins in effect.) When an
1969 :     instrumented module is linked, whatever plugins are at that time
1970 :     enabled will come into effect for that module.
1971 :    
1972 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
1973 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
1974 :     To enable the coverage plugin, load the same library and invoke
1975 :     Coverage.install().
1976 :    
1977 :     Back-traces are generated automatically on uncaught exceptions and
1978 :     when the code in question explicitly invokes BackTrace.trigger().
1979 :    
1980 :     Coverage (and execution frequency-) information must be queried
1981 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2002 :    
2003 :     This is is preparation of using the original back-trace
2004 :     instrumentation for other purposes. "TDP" stands for
2005 :     Trace/Debug/Profile.
2006 :    
2007 :     The control flag controlling whether instrumentation is on or off is now

2010 :     sml -Cinstrument.btrace-mode=true

2034 :     "*", and "-" as ordinary identifiers rather than keywords.
2035 :    
2036 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool
2037 :     is supposed to accept a tool argument called "source", but this did
2038 :     not work because of the clash with the keyword.

2084 : mblume 1672 src/system/smlnj/internal. This avoids expensive reconstruction of
2085 :     a stable src/compiler/core.cm.
2086 : mblume 1639
2087 : mblume 1672 * At the same time, structure CompilerVersion is now known as
2088 :     structure SMLNJVersion.
2089 : mblume 1639
2090 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2091 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2092 :     Also, loading the versiontool does not work when rebuilding the system
2093 :     because CM is not properly initialized at that time.

2098 :     Tag: blume-20040929-autoversion
2099 :     Description:
2100 :    
2101 :     Implemented some CM magic to have
2102 :     file src/compiler/TopLevel/main/version.sml
2103 :     generated automagically.
2104 :     The version is taken from two files: config/version and config/release.
2105 :     The first is expected to contain a two-part version number such as 110.49.
2106 :     The second should contain a single number, but it may be missing.
2107 :    
2108 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2109 :     time the version tool is loaded (which is the first time you say CMB.make),
2110 :     then the tool will increment the value stored in config/release every
2111 :     time CMB.make is invoked.
2112 :    
2113 :     The binfile format is now insensitive to anything beyond the first
2114 :     two components of a version number, so bumping the release does not render
2115 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2116 :     during development without invalidating existing binfiles.
2117 :    
2118 :     In any case, every CMB.make updates the date information in version.sml.
2119 :     (This is the date that is printed in the banner.)

2132 :     Tag: blume-20040927-controls
2133 :     Description:
2134 :    
2135 :     Added two pieces of functionality to the Controls interface:
2136 :    
2137 :     1. val save'restore: 'a control -> unit -> unit
2138 :    
2139 :     grabs the current value of the control in stage 1 and restores it
2140 :     in stage 2.
2141 :    
2142 :     2. val set' : 'a control * 'a -> unit -> unit
2143 :    
2144 :     stores the given value into the control in stage 2 (i.e., delayed)
2145 :     but does all error checking in stage 1.
2146 :     (This is for string controls that need to do parse their argument --
2147 :     something that might fail. In some cases, notably in CM, one
2148 :     already knows the intended argument but wants to delay the actual
2149 :     assignment until a time when error recovery would be more difficult.)
2150 :    
2151 :     Changed the handling of controls in tool arguments to classes "sml" and
2152 :     "lazysml":
2153 :     - use Controls.save'restore as a more robust way of restoring the
2154 :     old value (in particular: without having to re-parse the string)
2155 :     - use controls to handle the "overload" keyword in the init group
2156 :     (I believe this change actually fixes a long-standing obscure bug.)

2161 :     Tag: blume-20040927-lazysml
2162 :     Description:
2163 :    
2164 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2165 :     difference to "sml" is that compilation is done with Control.lazysml
2166 :     set to true. A source of class "lazysml" is automatically recognized
2167 :     by a file name suffix of ".lml".
2168 :    
2169 :     In addition to the above feature, the original class "sml" now also
2170 :     supports a tool argument "lazy" which has the same effect. As a
2171 :     result, the following three lines are equivalent:
2172 :    
2173 :     foo.sml : lazysml
2174 :     foo.sml : sml (lazy)
2175 :     foo.sml (lazy)
2176 :    
2177 :     The setting goes into effect both during parsing and during
2178 :     compilation. The original setting is restored right after parsing and
2179 :     after compilation, respectively.
2180 :    
2181 :     In addition to all the above, there is also a general mechanism to set
2182 :     ANY of the "controls" that are available at the command line via
2183 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2184 :     apply as well. (In fact, "lazy" is implemented as a special case of
2185 :     the general mechanism.)
2186 :    
2187 :     The .cm file syntax uses a new keyword tool argument called "with".
2188 :     There are several ways of indicating the desired settings:
2189 :    
2190 :     foo.sml (with:parser.quotations=true)
2191 :     foo.sml (with:(name:parser.quotations value:true))
2192 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2193 :     foo.sml (with:(name1=value1 name2=value2 ...))
2194 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2195 :    
2196 :     etc.
2197 :    
2198 :     Another possible abbreviation is to leave out the =v or value:v part
2199 :     if the name refers to a boolean control (in which case the value is
2200 :     taken to be true). Thus, one could get lazy sml also by saying:
2201 :    
2202 :     foo.sml (with:parser.lazy-keyword=true)
2203 :     foo.sml (with:parser.lazy-keyword)
2204 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2205 :     foo.sml (with:(name:parser.lazy-keyword))

2502 :     Description:
2503 :    
2504 :     - use paramAlloc to report c-calls with too many arguments
2505 :     (for PPC version where parameter area is pre-allocated)
2506 :     - added ccall_maxargspace to machspec (to implement the above)
2507 :     - made "make" commend in CM's "make" tool configurable
2508 :     - added option (default: on) for passing the name of the SML/NJ's "bin"
2509 :     directory to "make"; the call looks like this:
2510 :    
2511 :     make <options> SMLNJ_BINDIR=<dir> <target>
2512 :    
2513 :     This can be used by the Makefile to, e.g., pick the "right" version
2514 :     of ml-nlffigen.

2523 :     NLFFI under Mac OS X now working (sort of). This is largely untested,
2524 :     though.
2525 :    
2526 :     Note: 1. You have to make a new, clean build of the runtime system.

2528 :     (Doing the bootstrap process yourself would be *very* painful!
2529 :     If you absolutely have to do it, build the system under

2531 :    
2532 :     Version bumped to 110.46.1 to account for runtime data format changes.

2556 :     Tag: blume-20040617-timer-unix
2557 :     Description:
2558 :    
2559 :     Changed the interface of structures Timer and Unix to match the most
2560 :     recent Basis spec.
2561 :    
2562 :     In the case of Unix there still seems to be an open/weird issue:
2563 :    
2564 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2565 :     fresh streams whenever they are called -- as opposed to have them
2566 :     return the same stream every time. This design is supposed to
2567 :     prevent space leaks caused by proc values hanging on to streams.
2568 :    
2569 :     The reap function, on the other hand, is supposed to close the
2570 :     streams. This cannot be done without having a handle on the
2571 :     stream in proc after all...
2572 :    
2573 :     I took the liberty to implement the following stopgap solution:
2574 :    
2575 :     The proc value hangs on to the most recently created stream(s).
2576 :     Reap closes those. If either or both of the two streams hadn't
2577 :     been created at all yet, then reap will close the corresponding
2578 :     file descriptors directly.
2579 :    
2580 :     PS: I don't understand the original space leak argument anymore. If
2581 :     a proc hangs on to the imperative stream, then I/O operations on those
2582 :     will advance the state of the cached stream and avoid the space leak.

2595 :     Tag: blume-20040525-group-owner
2596 :     Description:
2597 :    
2598 :     CM now ignores (but still accepts) the "owner" information in group
2599 :     descriptions. The owner of a group is its next enclosing
2600 :     library. Each group must have a unique owner. (There is a virtual
2601 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2602 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2603 :     and CM would check that such a declaration is correct. The new scheme
2604 :     is to have CM check that for each group there is precisely one owning
2605 :     library.
2606 :    
2607 :     The advantage of the new scheme is that the programmer no longer needs
2608 :     to maintain the somewhat annoying owner information. The downside is
2609 :     that CM cannot enforce the ownership rule across multiple runs of
2610 :     CM.make. Fortunately, enclosing the same group in two different
2611 :     libraries A and B which are not part of the same program does not
2612 :     cause real problems.

2622 :     compiled correctly.)
2623 :

2631 :     Description:
2632 :    
2633 :     Arranged for ml-build to clean up after itself a little bit better.
2634 :     The script generates a temporary SML source file and compiles it using
2635 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
2636 :     gets rid of those at the end, so they don't accumulate under .cm.
2637 :    
2638 :     This required a minor change to install.sh because the name of the
2639 :     metadata directory (default: .cm) is actually configurable at
2640 :     installation time.

2656 :    
2657 :     Added previously missing support for many socket-related functions
2658 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
2659 :     for the voluminous patch!
2660 :    
2661 :     (I have not tested this patch under win32 yet.)
2662 :    
2663 : mblume 1490 Here is David's e-mail:
2664 :    
2665 :     Hi,
2666 :    
2667 :     Attached to this email you find a diff against sml/nj 110.45
2668 :     that will enable socket support under Windows.
2669 :    
2670 :     To apply the patch (using unix or cygwin)
2671 :     1) gunzip runtime.diff.gz
2672 :     2) "cd" into "src/runtime" in the source tree of a fresh
2673 :     110.45 installation.
2674 :     3) patch -p 1 < [your/path/to]runtime.diff
2675 :    
2676 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2677 :     I only ran a few tests for basic socket client functionality
2678 :     (which worked fine). Especially the functions that use ioctl
2679 : mblume 1490 are not tested at all and might not work (see below).
2680 :    
2681 :     I implemented this since we want to move to a newer version of sml/nj
2682 :     but need socket support in order to use it. This is the first time I
2683 :     even had a look at the sml/nj source, so please review my changes
2684 :     before making this part of the distribution! Here are a few issues
2685 : blume 2155 that I think might be better for someone to solve who is more
2686 : mblume 1490 familiar with the sml/nj source (and socket programming):
2687 :    
2688 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2689 :     exception since I could not figure out what the windows equivalent
2690 :     of these functions is
2691 :    
2692 :     - In sockets-osdep.h there are a some #include statements that are
2693 :     only used in a few files that include sockets-osdep.h
2694 :    
2695 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2696 :     does not process its return value since I don't know how to
2697 :     report an error upwards.
2698 :    
2699 :     - It would probably be good to have a call to WSACleanup() when
2700 : blume 2155 the library is unloaded (if there is such a possibility).
2701 : mblume 1490 Otherwise I think Windows will take care of this automatically
2702 :     when the process finishes.
2703 :    
2704 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2705 :     no idea if that is actually the proper replacement on Windows.
2706 :    
2707 :     - All these issues are marked in the code by "FIXME" comments.
2708 :    
2709 : blume 2155 We use sml/nj extensively in our products and are quite happy
2710 :     with it. I hope this contribution will help you.
2711 : mblume 1490
2712 :     Keep up the good work!

2877 :     Description:
2878 :    
2879 :     Eliminated the "dont_move_libraries" directive in config/targets.
2880 :     (The mechanism was broken and could not be fixed easily. Moreover,
2881 :     there does not seem to be any reason not to move all libraries into
2882 :     lib during installation. I originally implemented this directive as a
2883 :     backward-compatibility feature when I first introduced the new CM.
2884 :     Now that things have been stable for a long time and going back to the
2885 :     old CM is not an option, there is no reason to keep it around.)

2934 :     Tag: blume-20030926-ppautoload
2935 :     Description:
2936 :    
2937 :     I modified the read-eval-print loop so that the autoloader gets
2938 :     invoked whenever the prettyprinter tries to look up a symbol that
2939 :     is not currently defined in the toplevel environment but which
2940 :     appears in CM's autoload registry. As a result, we see far fewer of
2941 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
2942 :    
2943 :     In addition to this I tried to clean up some pieces of the Basis
2944 :     implementation (e.g., Socket, Word8Array) in order to prevent other
2945 :     instances of these ?.Foo.Bar.xxx names from being printed.
2946 :    
2947 :     The mechanism that picks names for types still needs some work, though.
2948 :     (Right now it seems that if there is a type A.t which is defined to
2949 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
2950 :     "?.B.u" although the perhaps more sensible solution would be to use
2951 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
2952 :     a chain of DEFtycs not farther than there are corresponding toplevel
2953 :     names in the current environment.)

2959 :     Description:
2960 :    
2961 :     Another installer tweak: All the ML code for the installer is now
2962 :     compiled during CMB.make and put into a little library called
2963 :     $smlnj/installer.cm. The installation then simply invokes
2964 :    
2965 :     sml -m $smlnj/installer.cm
2966 :    
2967 :     and everything happens automagically.
2968 :    
2969 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
2970 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
2971 :     and BINDIR.
2972 :    
2973 :     The new scheme guarantees that the ML code responsible for the installation
2974 :     is in sync with the APIs of the main system. Also, the installer is
2975 :     somewhat faster because the installer script is precompiled.

2983 :     Added a signature SYNCHRONOUS_SOCKET to basis.cm. This is like SOCKET
2984 :     but excludes all non-blocking operations. Defined SOCKET (in Basis)
2985 :     and CML_SOCKET in terms of SYNCHRONOUS_SOCKET. Removed superfluous
2986 :     implementations of non-blocking operations from CML's Socket
2987 :     structure.

2992 :     Tag: blume-20030924-sockets
2993 :     Description:
2994 :    
2995 :     1. Fixed SOCKET API and implementation to match Basis spec.
2996 :     This required changing the internal representation of sockets to one
2997 :     that remembers (for each socket file descriptor) whether it is currently
2998 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
2999 :     call is made only if the state actually needs to change).
3000 :    
3001 :     2. OS-specific details of sockets were moved into separate files, thus
3002 :     making it possible to unify the bulk of the socket implementations
3003 :     between Unix and Win32.
3004 :    
3005 :     3. CML's socket API changed accordingly.
3006 :     (Note that we need to remove non-blocking functions from this API
3007 :     since they are redundant in the case of CML!)
3008 :    
3009 :     4. CML's socket implementation now makes use of non-blocking functions
3010 :     provided by Basis, thus removing all OS-dependent code from this part
3011 :     of CML.
3012 :    
3013 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3126 :     Description:
3127 :    
3128 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3129 :     Modified config/install.bat to take advantage of it. Also modified
3130 :     config/install.sh (and called it config/new-install.sh) to take advantage
3131 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3132 :     independent.)
3133 :    
3134 :     The installer can now install everything under Win32
3135 :     as well as under *nix as long as it compiles.
3136 :    
3137 :     Other changes:
3138 :    
3139 :     - made CML compile again under Win32
3140 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3141 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3142 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3143 :     same as type int; under Win32 it isn't
3144 :     - fixed some slice-related problems in the win32-specific parts of CML
3145 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3146 :     (under Win32, the volume name is case-insensitive, and the
3147 :     OS.Path code compares volume names for equality)

3164 : mblume 1350 Description:
3165 :    
3166 :     1. Changed interface to vectors and arrays in Basis to match
3167 :     (draft) Basis spec.
3168 :     2. Added signatures and implementations of slices according to
3169 :     Basis spec.
3170 :     3. Edited source code throughout the system to make it compile again
3171 :     under 1. and 2. (In some cases code had to be added to have it
3172 :     match the new signatures.)
3173 :     4. MLRISC should be backward-compatible: the copies of the originals
3174 :     of files that needed to change under 3. were retained, the .cm files
3175 :     check the compiler version number and use old versions when
3176 :     appropriate.
3177 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3178 :     dirstream -> string option (in accordance with Basis spec).
3179 :     6. When generating code that counts lines, ml-lex used function
3180 :     CharVector.foldli, taking advantage of its old interface.
3181 :     This has been replaced with the corresponding code from
3182 :     CharVectorSlice. (html-lex must be re-lexed!)
3183 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3184 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3185 :     8. Removed temporary additions (fromInternal, toInternal) from the
3186 :     (now obsolete) IntInf in smlnj-lib/Util.
3187 :     9. Cleaned up structure Byte.
3188 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3189 :     Cleaned/corrected implementation of Date.
3190 :     (Still need to check for correctness; implement better canonicalizeDate.)
3191 :     11. Added "scan" to signature IEEE_REAL.
3192 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3193 :     mod and rem when second operand is 2 (for parity checks).]
3194 :     13. Changed representation of type Time.time, using a single IntInf.int
3195 :     value counting microseconds. This considerably simplified the
3196 :     implementation of structure Time. We now support negative time
3197 :     values; scan and fromString handle signs.
3198 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3199 :     ArraySlice).

3205 :     Description:
3206 :    
3207 :     This is a major update which comes with a version number bump
3208 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3209 :     and an implementation of IntInf in the Basis.
3210 :    
3211 :     There are a fairly large number of related changes and updates throughout
3212 :     the system:
3213 :    
3214 :     Basis:
3215 :     - Implemented IntInf.
3216 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3217 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3218 : mblume 1347 - Added FixedInt as a synonym for Int32.
3219 :    
3220 :     compiler:
3221 :     * Added support for a built-in intinf type.
3222 :     - literals
3223 :     - pattern matching
3224 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3225 :     - overloading on literals and operations
3226 :    
3227 :     This required adding a primitive type intinf, some additional
3228 :     primops, and implementations for several non-trivial intinf
3229 :     operations in Core. (The intinf type is completely abstract
3230 :     to the compiler; all operations get delegated back to the Core.)
3231 :    
3232 :     * Intinf equality is handled by polyequal. However, the compiler
3233 :     does not print its usual warning in this case (since polyequal
3234 :     is the right thing to do there).
3235 :    
3236 :     * Improved the organization of structure InlineT.
3237 :    
3238 :     * A word about conversion primops:
3239 :     If conversions involving intinf do not cancel out during
3240 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3241 : mblume 1347 Since all core access must be resolved already during the FLINT
3242 :     translate phase, it would be too late a the time of CPS contract
3243 : mblume 1348 to add new Core calls. For this reason, conversion primops
3244 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3245 :     they are supposed to convert, and 2. the Core function that
3246 :     can help with this conversion if necessary. If CPS contract
3247 : mblume 1348 eliminates a primop, then the associated Core function becomes
3248 :     dead and goes away. Intinf conversion primops that do not get
3249 :     eliminated by CPS contract get rewritten into calls of their
3250 :     core functions by a separate, new phase.
3251 : mblume 1347
3252 :     interactive system:
3253 :     - Control.Print.intinfDepth controls max length of intinf constants
3254 :     being printed. (Analogous to Control.Print.stringDepth.)
3255 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3256 :     duplicates; replaced some of the code with code that makes better

3258 :    
3259 :     CM:
3260 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3261 :     are no longer silent.
3262 :    
3263 :     CKIT:
3264 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3265 :     in favor of LargeInt -- which is now the same as IntInf.
3266 :     CKIT-knowledgable people should check whether this is what's
3267 :     intended and otherwise change things back to using Int32 or
3268 :     FixedInt.
3269 :    
3270 :     Throughout the code:
3271 : mblume 1348 Started using IntInf.int literals and built-in operations
3272 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3291 :     Tag: blume-20030811-windows
3292 :     Description:
3293 :    
3294 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3295 :    
3296 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3297 :    
3298 :     This patch restores SML/NJ's ability to run under win32. There are a
3299 :     number of changes, including fixes for several bugs that had gone
3300 :     unnoticed until now:
3301 :    
3302 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3303 :     trying to run the win32 version from within cygwin.)
3304 :    
3305 :     - There are a number of simple .bat scripts that substitute for their
3306 :     corresponding Unix shell-scripts. (See below.)
3307 :    
3308 :     - The internals of ml-build have been modified slightly. The main
3309 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3310 :     using OS.Process.system, the ML process delegates this task back
3311 :     to the script. Otherwise problems arise in mixed environments such
3312 :     as Cygwin where scripts look and work like Unix scripts, but
3313 :     where OS.Process.system cannot run them.
3314 :    
3315 :     - In CM, the srcpath pickler used native pathname syntax -- which
3316 :     is incorrect in the case of cross-compilation. The new pickle format
3317 :     is independent of platform-specific naming conventions.
3318 :    
3319 :     - Path configuration files (such as lib/pathconfig) can now choose
3320 :     between native and standard syntax. Placing a line of the form
3321 :    
3322 :     standard!
3323 :    
3324 :     into the file causes all subsequent paths to be interpreted using
3325 :     CM standard pathname syntax (= Unix conventions); a line
3326 :    
3327 :     native!
3328 :    
3329 :     switches back to native style. This was needed so that
3330 :     path config files can be written portably, see src/system/pathconfig.
3331 :    
3332 :     - Runtime system:
3333 :    
3334 :     - win32-filesys.c: get_file_time and set_file_time now
3335 :     access modification time, not creation time.
3336 :    
3337 :     - I/O code made aware of new array representation.
3338 :    
3339 :     - Bug fixes in X86.prim.masm.
3340 :    
3341 :     - src/system/makeml made aware of win32. (For use under cygwin
3342 :     and other Unix-environments for windows.)
3343 :    
3344 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3345 :     which caused BinIO.inputAll to fail consistently.
3346 :    
3347 :     .bat scripts:
3348 :    
3349 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3350 :    
3351 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3352 :     applications (sml, ml-yacc, ml-lex).
3353 :     - ml-build.bat: analogous to ml-build.
3354 :     - config\install.bat: Analogous to config/install.sh. This requires
3355 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3356 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3357 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3358 :     and the bootfile hierarchy must have been unpacked under
3359 :     sml.boot.x86-win32.
3360 :     The script is very primitive and does a poor job at error checking.
3361 :     It only installs the base system, ml-lex, and ml-yacc. No other
3362 :     libraries are being installed (i.e., you get only those that
3363 :     are part of the compiler.)
3364 :     - link-sml.bat: analogous to .link-sml, but not currently used
3365 :    
3366 :     Unrelated bug fixes:
3367 :    
3368 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3369 :     types.
3370 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3371 :     otherwise.)

3395 :     Description:
3396 :    
3397 :     Two changes:
3398 :

3400 :     be treated as errors (default is false).
3401 :     2. Cleaned up the *entire* source tree so that CMB.make goes through

3408 :     Description:
3409 :    
3410 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3411 :    
3412 :     This mainly affects the quality of error messages. However, some
3413 :     of the code is now more straightforward than before. (Treatment of
3414 :     the above four constructs in translate.sml is much simpler than
3415 :     the "macro-expansion" that was going on before. Plus, the mach-
3416 :     compiler no longer gets invoked just to be able to compile an
3417 :     if-expression.)
3418 :    
3419 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3420 :     interactive loop.

3426 :     Description:
3427 :    
3428 : blume 2155 Ported the runtime system to cygwin, which uses the unix

3430 :    
3431 : blume 2155 o getnetbyname, getnetbyaddr: these functions seem to be missing in
3432 : allenleung 1327 the Cygwin library.
3433 :     o Ctrl-C handling may be flaky.
3434 :     o Windows system calls and Windows I/O are not supported.
3435 :    
3436 :     A new set of binfiles is located at:
3437 :    
3438 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3439 :    
3440 :     This is only needed for bootstrapping the cygwin version of smlnj.
3441 :     Other x86 versions can use the existing binfiles.

3471 :     110.37 and 110.38.)

3473 :     MLRISC annotations (but those did not yet cause real problems, apparently).

3479 :     Description:
3480 :

3482 :     This fixes the problem of CM getting confused by files that suddenly
3483 :     change their identity (e.g., by getting unlinked and recreated by some
3484 :     text editor such as vi). There might be a better/cheaper/cleaner way

3673 :     (Many libraries, e.g., CML, do not exist yet at this time. The
3674 :     only libraries that can be preloaded via config/preloads are those
3675 :     that come bundled with the bootfiles.)

3700 :     Description:
3701 :    
3702 :     0. John Reppy made several modifications to the SML/NJ library.
3703 :     In particular, there is a shiny new controls-lib.cm.
3704 :    
3705 :     1. Pushed new controls interface through compiler so that everything
3706 :     compiles again.
3707 :    
3708 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3709 :     SML/NJ library (so that CML compiles again).
3710 :    
3711 :     3. Modified init scripts because XXX_DEFAULT environment variables
3712 :     are no longer with us. (Boot-time initialization is now done
3713 :     using the same environment variables that are also used for
3714 :     startup-time initialization of controls.)

3720 :     Description:
3721 :    
3722 :     All pseudo-ops emitted before the first segment declaration
3723 :     such as TEXT, DATA, and BSS directives are assumed to be global
3724 :     declarations and are emitted first in the assembly file. This is
3725 :     useful in a number of situations where one has pseudo-ops that are not
3726 :     specific to any segment, and also works around the constraint that one
3727 :     cannot have client pseudo-ops in the TEXT segment.
3728 :    
3729 :     Because no segment is associated with these declarations it is
3730 :     an error to allocate any space or objects before the first segment
3731 :     directive and an exception will be raised. However, we cannot make
3732 :     this check for client pseudo-ops.
3733 :    
3734 :     These top level declarations are a field in the CFG graph_info.
3735 :     In theory you can continue to add to this field after the CFG has been
3736 :     built -- provided you know what you are doing;-)

3746 :     - Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
3747 :     (Bogus printouts for redefined bindings still occur. Compiler

3759 :     Description:
3760 :    
3761 :     Applied the following bugfix provided by Emden Gansner:
3762 :    
3763 :     Output is corrupted when outputSubstr is used rather than output.
3764 :    
3765 : blume 2155 The problem occurs when a substring
3766 : blume 1189
3767 :     ss = (s, dataStart, dataLen)
3768 :    
3769 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3770 :     avail bytes of s, starting at index dataStart, are copied into the
3771 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3772 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3773 :     starting this copy at index dataStart+avail in s, the current code
3774 : blume 1189 starts the copy at index avail.
3775 :    
3776 :     Fix:
3777 :     In text-io-fn.sml, change line 695 from
3778 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3779 : blume 2155 to

3796 :     Description:
3797 :    
3798 :     Added full support for div/mod/rem/quot on the x86, using the machine
3799 :     instruction's two results (without clumsily recomputing the remainder)
3800 :     directly where appropriate.
3801 :    
3802 :     Some more extensive power-of-two support was added to the x86 instruction
3803 :     selector (avoiding expensive divs, mods, and muls where they can be
3804 :     replaced with cheaper shifts and masks). However, this sort of thing
3805 :     ought to be done earlier, e.g., within the CPS optimizer so that
3806 :     all architectures benefit from it.
3807 :    
3808 :     The compiler compiles to a fixed point, but changes might be somewhat
3809 :     fragile nevertheless. Please, report any strange things that you might
3810 :     see wrt. div/mod/quot/rem...

3817 :    
3818 :     Fixed my broken div/mod logic. Unfortunately, this means that the

3820 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3821 :     The problem was with quotient = 0, because that alone does not tell
3822 :     us which way the rounding went. One then has to look at whether
3823 :     remainder and divisor have the same sign... :(

3831 :     Description:
3832 :    
3833 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
3834 :    
3835 :     Primops have changed. This means that the bin/boot-file formats have
3836 :     changed as well.
3837 :    
3838 :     To make sure that there is no confusion, I made a new version.
3839 :    
3840 :    
3841 :     CHANGES:
3842 :    
3843 :     * removed REMT from mltree (remainder should never overflow).
3844 :    
3845 :     * added primops to deal with divisions of all flavors to the frontend
3846 :    
3847 :     * handled these primops all the way through so they map to their respective
3848 :     MLRISC support
3849 :    
3850 :     * used these primops in the implementation of Int, Int32, Word, Word32
3851 :    
3852 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3853 :    
3854 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
3855 :    
3856 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3857 :     floating point
3858 :    
3859 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3860 :     and Real (but Real.abs maps to a separate floating-point-only primop)
3861 :    
3862 :    
3863 :     TODO items:
3864 :    
3865 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
3866 :     instructions because the machine instruction encoder cannot handle
3867 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
3868 :     REM in the first place, and REM is supported by the x86 machine coder.)
3869 :    
3870 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
3871 :     selection phase. (The two can be streamlined because the hardware
3872 :     delivers both quotient and remainder at the same time anyway.)
3873 :    
3874 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
3875 :     (Currently the behavior is inconsistent both across architectures and
3876 :     wrt. the draft Basis spec.)
3877 :    
3878 :     * Word8 should eventually be handled natively, too.
3879 :    
3880 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
3881 :     as if there currently is no execution path that could trigger it in
3882 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
3883 :     hold for things like multiplication and division.)

3888 :     Tag: blume-20020327-mlrisc-divisions
3889 :     Description:
3890 :    
3891 :     Added support for all four division operations (ML's div, mod, quot,
3892 :     and rem) to MLRISC. In the course of doing so, I also rationalized
3893 :     the naming (no more annoying switch-around of DIV and QUOT), by
3894 :     parameterizing the operation by div_rounding_mode (which can be either
3895 :     DIV_TO_ZERO or DIV_TO_NEGINF).
3896 :    
3897 :     The generic MLTreeGen functor takes care of compiling all four
3898 :     operations down to only round-to-zero div.
3899 :    
3900 :     Missing pieces:
3901 :    
3902 :     * Doing something smarter than relying on MLTreeGen on architectures
3903 :     like, e.g., the x86 where hardware division delivers both quotient and
3904 :     remainder at the same time. With this, the implementation of the
3905 :     round-to-neginf operations could be further streamlined.
3906 :    
3907 :     * Remove inlining support for div/mod/rem from the frontend and replace it
3908 :     with primops that get carried through to the backend. Do this for all
3909 :     int and word types.

3914 :     Tag: blume-20020325-divmod
3915 :     Description:
3916 :    
3917 :     I improved (hopefully without breaking them) the implementation of Int.div,
3918 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
3919 :     advantage of the following observations:
3920 :    
3921 :     Let q = x quot y r = x rem y
3922 :     d = x div y m = x mod y
3923 :    
3924 :     where "quot" is the round-to-zero version of integer division that
3925 :     hardware usually provides. Then we have:
3926 :    
3927 :     r = x - q * y where neither the * nor the - will overflow
3928 :     d = if q >= 0 orelse x = q * y then q else q - 1
3929 :     where neither the * nor the - will overflow
3930 :     m = if q >= 0 orelse r = 0 then r else r + y
3931 :     where the + will not overflow
3932 :    
3933 :     This results in substantial simplification of the generated code.
3934 :     The following table shows the number of CFG nodes and edges generated
3935 :     for
3936 :     fun f (x, y) = x OPER y
3937 :     (* with OPER \in div, mod, quot, rem *)
3938 :

3979 :    
3980 :     1. Changes to FLINT primops:
3981 :    
3982 :     (* make a call to a C-function;
3983 :     * The primop carries C function prototype information and specifies
3984 :     * which of its (ML-) arguments are floating point. C prototype
3985 :     * information is for use by the backend, ML information is for
3986 :     * use by the CPS converter. *)
3987 :     | RAW_CCALL of { c_proto: CTypes.c_proto,
3988 :     ml_args: ccall_type list,
3989 :     ml_res_opt: ccall_type option,
3990 :     reentrant : bool
3991 :     } option
3992 :     (* Allocate uninitialized storage on the heap.
3993 :     * The record is meant to hold short-lived C objects, i.e., they
3994 : blume 2155 * are not ML pointers. With the tag, the representation is
3995 : leunga 1174 * the same as RECORD with tag tag_raw32 (sz=4), or tag_fblock (sz=8)
3996 :     *)
3997 : blume 2155 | RAW_RECORD of {tag:bool,sz:int}
3998 : leunga 1174 and ccall_type = CCALL_INT32 | CCALL_REAL64 | CCALL_ML_PTR
3999 :    
4000 :     2. These CPS primops are now overloaded:
4001 :    
4002 :     rawload of {kind:numkind}
4003 :     rawstore of {kind:numkind}
4004 :    
4005 :     The one argument form is:
4006 :    
4007 :     rawload {kind} address

4010 : blume 2155
4011 : leunga 1174 rawload {kind} [ml object, byte-offset]
4012 :    
4013 :     3. RAW_CCALL/RCC now takes two extra arguments:
4014 :    
4015 :     a. The first is whether the C call is reentrant, i.e., whether
4016 :     ML state should be saved and restored.
4017 :     b. The second argument is a string argument specifying the name of
4018 :     library and the C function.
4019 :    
4020 :     These things are currently not handled in the code generator, yet.
4021 :    
4022 :     4. In CProto,
4023 :    
4024 : blume 2155 An encoding type of "bool" means "ml object" and is mapped into
4025 :     C prototype of PTR. Note that "bool" is different than "string",
4026 : leunga 1174 even though "string" is also mapped into PTR, because "bool"
4027 :     is assigned an CPS type of BOGt, while "string" is assigned INT32t.
4028 :    
4029 :     5. Pickler/unpicker
4030 :    
4031 :     Changed to handle RAW_RECORD and newest RAW_CCALL
4032 :    
4033 :     6. MLRiscGen,
4034 :    
4035 :     1. Changed to handle the new rawload/rawstore/rawrecord operators.
4036 :     2. Code for handling C Calls has been moved to a new module CPSCCalls,
4037 :     in the file CodeGen/cpscompile/cps-c-calls.sml
4038 :    
4039 :     7. Added the conditional move operator
4040 :    
4041 :     condmove of branch
4042 :

4051 :    
4052 : blume 2155 Implemented the Ball-Larus branch prediction-heuristics, and
4053 : george 1168 incorporated graphical viewers for control flow graphs.
4054 :    
4055 : george 1171 Ball-Larus Heuristics:
4056 : george 1168 ---------------------
4057 :     See the file compiler/CodeGen/cpscompile/cpsBranchProb.sml.
4058 :    
4059 :     By design it uses the Dempster-Shafer theory for combining
4060 :     probabilities. For example, in the function:
4061 :    
4062 :     fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)
4063 :    
4064 :     the ball-larus heuristics predicts that the n=0 is unlikely
4065 :     (OH-heuristic), and the 'then' branch is unlikely because of the
4066 :     RH-heuristic -- giving the 'then' branch an even lower combined
4067 : george 1171 probability using the Dempster-Shafer theory.
4068 : george 1168
4069 :     Finally, John Reppy's loop analysis in MLRISC, further lowers the
4070 :     probability of the 'then' branch because of the loop in the else
4071 :     branch.
4072 :    
4073 :    
4074 :     Graphical Viewing:
4075 : blume 2155 ------------------
4076 : george 1168 I merely plugged in Allen's graphical viewers into the compiler. The
4077 :     additional code is not much. At the top level, saying:
4078 :    
4079 :     Control.MLRISC.getFlag "cfg-graphical-view" := true;
4080 :    
4081 :     will display the graphical view of the control flow graph just before
4082 :     back-patching. daVinci must be in your path for this to work. If
4083 :     daVinci is not available, then the default viewer can be changed
4084 :     using:
4085 :    
4086 :     Control.MLRISC.getString "viewer"
4087 :    
4088 :     which can be set to "dot" or "vcg" for the corresponding viewers. Of
4089 :     course, these viewers must be in your path.
4090 :    
4091 :     The above will display the compilation unit at the level of clusters,
4092 :     many of which are small, boring, and un-interesting. Also setting:
4093 :    
4094 :     Control.MLRISC.getInt "cfg-graphical-view_size"
4095 :    
4096 :     will display clusters that are larger than the value set by the above.

4104 :    
4105 :     Changed the interface to the KMP routine in PreString and fixed
4106 :     a minor bug in one place where it was used.

4120 :     Description:
4121 :    
4122 : blume 2155 1. Recoded the buggy parts of x86-fp.
4123 : leunga 1156
4124 :     a. All the block reordering code has been removed.
4125 :     We now depend on the block placement phases to do this work.
4126 :    
4127 :     b. Critical edge splitting code has been simplified and moved into the
4128 :     CFG modules, as where they belong.
4129 :    
4130 :     Both of these were quite buggy and complex. The code is now much, much
4131 :     simpler.
4132 :    
4133 :     2. X86 backend.
4134 :    
4135 :     a. Added instructions for 64-bit support. Instruction selection for
4136 :     64-bit has not been committed, however, since that
4137 : blume 2155 requires changes to MLTREE which haven't been approved by
4138 : leunga 1156 Lal and John.
4139 :    
4140 : blume 2155 b. Added support for FUCOMI and FUCOMIP when generating code for
4141 : leunga 1156 PentiumPro and above. We only generate these instructions in
4142 :     the fast-fp mode.
4143 :    
4144 : blume 2155 c. Added cases for JP and JNP in X86FreqProps.
4145 :    
4146 : leunga 1156 3. CFG
4147 :    
4148 :     CFG now has a bunch of methods for edge splitting and merging.
4149 :    
4150 :     4. Machine description.
4151 :    
4152 :     John's simplification of MLTREE_BASIS.fcond broke a few machine
4153 :     description things:
4154 :    
4155 :     rtl-build.{sig,sml} and hppa.mdl fixed.
4156 :    
4157 : blume 2155 NOTE: the machine description stuff in the repository is still broken.
4158 :     Again, I can't put my fixes in because that involves
4159 :     changes to MLTREE.

4164 :     Tag: blume-20020320-kmp
4165 :     Description:
4166 :    
4167 :     Implemented Knuth-Morris-Pratt string matching in PreString and used
4168 :     it for String.isSubstring, Substring.isSubstring, and
4169 :     Substring.position.
4170 :    
4171 :     (Might need some stress-testing. Simple examples worked fine.)

4176 :     Tag: blume-20020319-witnesses
4177 :     Description:
4178 :    
4179 :     Added a structure C.W and functions convert/Ptr.convert to ml-nlffi-lib.
4180 :    
4181 :     This implements a generic mechanism for changing constness qualifiers
4182 :     anywhere within big C types without resorting to outright "casts".
4183 :     (So far, functions such as C.rw/C.ro or C.Ptr.rw/C.Ptr.ro only let you
4184 :     modify the constness at the outermost level.)
4185 :     The implementation of "convert" is based on the idea of "witness"
4186 :     values -- values that are not used by the operation but whose types
4187 :     "testify" to their applicability. On the implementation side, "convert"
4188 :     is simply a projection (returning its second curried argument). With
4189 :     cross-module inlining, it should not result in any machine code being
4190 :     generated.
