1 : dbm 2431 This is the HISTORY file for the SML/NJ repository.
2 : dbm 570
3 :     An entry should be made for _every_ commit to the repository.
4 :     The entries in this file will be used when creating the README
5 :     for new versions, so keep that in mind when writing the

129 :     Description:
130 :    
131 :     The GAS output now favors p2align over align, since the

208 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
209 :     Date: 2007/06/06 21:45:00 CDT
210 :     Description:
211 :    
212 :     - Aaron: fixed a number of bugs in ml-ulex.
213 :     - Matthias:
214 :     - added CM control "cm.force-tools"; this is false by default;
215 :     when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
216 :     will be forced to run regardless of whether or not their targets
217 :     are up-to-date
218 :     - changed installer code so that config/install.sh will re-build
219 :     heap images for all tools even if those heap images already existed
220 :    
221 :     ----------------------------------------------------------------------
222 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
223 :     Date: 2007/06/04 21:21:00 CDT
224 :     Description:
225 :    
226 :     After Aaron Turon's bug fix for ml-ulex (handling the ^ character
227 :     in legacy mode), re-ran the lexer generator on all lex input files
228 :     and committed the results.
229 :    
230 :     This should fix the problem with ckit and nlffi that was reported
231 :     by Vesa A. Norrman.

243 : dbm 2737 Date: 2007/05/31 14:55:00 CDT
244 :     Revision: 2650
245 : dbm 2649 Description:
246 :    
247 :     3rd merge of base from primop-branch-3 into the trunk.
248 :     Additional bug fixes included:
249 :    
250 :     * Timer.cpu_timer, etc. type printing corrected (by making
251 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
252 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
253 :     Stefan Monnier)
254 :    
255 :     ----------------------------------------------------------------------
256 : dbm 2611 Name: Matthias Blume (http://www.tti-c.org/blume/)
257 : dbm 2648 Date: 2007/05/31 11:40:00 CDT
258 :     Description:
259 :    
260 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
261 :    
262 :     Also, changed the handling of "no core access": When translate.sml
263 :     needs access to a core exception at a time when the core has not
264 :     been set up yet (this only happens when compiling system/smlnj/init/*),
265 :     then don't bother generating the corresponding tests.
266 :    
267 : dbm 2649 The old scheme was to generate a bogus value to be used in place of
268 :     the exception. Unfortunately, that confuses the plambda type checker.
269 :     Moreover, it does not do any good, because at runtime we don't expect
270 :     such an exception to be ever raised. (The code in system/smlnj/init/*
271 :     has to be written very carefully with this in mind!)
272 : dbm 2648
273 :     ----------------------------------------------------------------------
274 :     Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
275 :     Date: 2007/05/29
276 :     Description:
277 :    
278 :     Added FSQRT instructions for the AMD64 code generator.
279 :    
280 :     ----------------------------------------------------------------------
281 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
282 : dbm 2636 Date: 2007/05/29 19:00:00 CDT
283 :     Description:
284 :    
285 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
286 :     with an explicit test for zero division. This should fixes several
287 :     regressions and makes it possible for downstream optimization phases
288 :     to treat these operations as "pure" when they are applied to unsigned
289 :     operands.
290 :    
291 :     ----------------------------------------------------------------------
292 :     Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
293 :     Date: 2007/05/29
294 :     Description:
295 :    
296 :     Added the new MLRISC code generator for the AMD64. This version,
297 :     in contrast to the previous one, uses SSE registers and instructions
298 :     for all floating-point computations.
299 :    
300 :     ----------------------------------------------------------------------
301 :     Name: John Reppy (http://www.cs.uchicago.edu/~jhr)
302 :     Date: 2007/05/29
303 :     Description:
304 :    
305 :     A number of fixes related to the formatting of dates. These include fixes
306 :     for bugs #1415 and #1416. We also now correctly handle format characters that
307 :     lie outside the specified set.
308 :    
309 :     ----------------------------------------------------------------------
310 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
311 : dbm 2611 Date: 2007/05/23 22:30:00 CDT
312 :     Description:
313 :    
314 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
315 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
316 :    
317 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
318 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
319 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
320 :     while running CMB.make. The point is that the single symbol
321 :     NO_PLUGINS is definde in all three cases.)
322 :    
323 :     I changed the three locations within the sources that get compiled
324 :     during CMB.make where ml-yacc or ml-lex input is processed: When
325 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
326 :     is bypassed.
327 :    
328 :     When bootstrapping new versions of the compiler, there can be
329 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
330 :     are not available or otherwise not operational. In this case one can
331 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
332 :     do so, the following command should be issued at the interactive
333 :     prompt:
334 :    
335 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
336 :    
337 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
338 :     files that normally would be generated by ml-yacc and ml-lex.
339 :     (Copies of these files are in the repository.)

344 : dbm 2636 Revision: 2603
345 : dbm 2600 Description:
346 :    
347 : dbm 2636 2nd merge of base from primop-branch-3 into the trunk.
348 :     Additional bug fixes included:
349 : dbm 2600 Date.scan and Date.fromString fixed;
350 :     Overloading resolution fixed and some type printing problems corrected.
351 :

353 : dbm 2579 Name: Matthias Blume (http://www.tti-c.org/blume/)
354 : dbm 2595 Date: 2007/05/23 09:50:00 CDT
355 :     Description:
356 :    
357 :     Changed the installation mechanism for CM tool plugins. These are
358 :     just libaries and now get installed like ordinary libaries.
359 :    
360 :     There are now a number of new installation targets that give some
361 :     fine-grain control over what classes and suffixes are known, and what
362 :     they will map to.
363 :     See config/targets for details.
364 :    
365 :     The code that caused plugin installation as part of running a
366 :     tool's "build" script has been removed. (The build script is for
367 :     building, not for installing.)
368 :    
369 :     ----------------------------------------------------------------------
370 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
371 : dbm 2579 Date: 2007/05/22 11:50:00 CDT
372 :     Description:
373 :    
374 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
375 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
376 :     CM fail if a shell tool reports a non-success exit status. If
377 :     the control is set to true, then CM will press on after tool failures
378 :     in the event that the target files exist (even though they are
379 :     considered outdated). Turning the control to true can be useful for
380 :     bootstrapping.
381 :    
382 :     ----------------------------------------------------------------------
383 :     Name: Aaron Turon (http://www.cs.uchicago.edu/~adrassi)
384 :     Date: 2007/05/19
385 :     Description:
386 :    
387 :     Merge of ml-lpt revisions for 110.64.
388 :    
389 :     The name of several ml-lpt-lib modules has changed:
390 :     Repair => AntlrRepair
391 :     StreamPos => AntlrStreamPos
392 :     ErrHandlerFn => AntlrErrHandler
393 :     EBNF => AntlrEBNF
394 :    
395 :     The ml-antlr specification format has changed: declarations such as
396 :     %tokens and nonterminal definitions can occur *multiple* times in the
397 :     same specification. The semantics are such that each new declaration
398 :     extends the previous ones. This does not apply to %start or %name,
399 :     of course.
400 :    
401 :     Importing a grammar via %import now includes *all* declarations in from
402 :     the imported grammar, except for %name, %entry, and %start. Tokens
403 :     and nonterminals can be dropped using the new %dropping clause of the
404 :     %import directive; the separate %drop and %extend have been removed.
405 :    
406 :     We now allow optional type annotations on nonterminals, using the %nonterms
407 :     directive as in ml-yacc.
408 :    
409 :     The refcell construct is now implemented using SML's regular reference
410 :     cells, so the :== and !! notation has been deprecated.
411 :    
412 :     The ml-antlr tool now does much more checking of specifications, and
413 :     its error messages have been greatly improved. Error repair for
414 :     generated parsers has been completely rewritten, and is now both
415 :     much faster and more accurate.
416 :    
417 :     ml-ulex is now more lenient with escape codes (non-SML-standard
418 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
419 :     Also, character classes may now include a "-" character at the beginning
420 :     as is standard in most other regexp tools.
421 :    
422 :     All of these changes are documented in the user guide, which has
423 :     been updated and improved with this merge.

429 :     Description:
430 :    
431 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
432 :     Significant changes in FLINT and the front end, mostly having to do
433 :     with a reorganized system for handling primops. Various bug fixes
434 :     and improvements in printing signatures.

442 :     The ml-antlr specification format has changed: declarations such as
443 :     %tokens and nonterminal definitions can occur *multiple* times in the
444 :     same specification. The semantics are such that each new declaration
445 :     extends the previous ones. Grammar extension constructs have also
446 :     changed. We now allow type annotations on nonterminals. Finally,
447 :     the refcell construct is now implemented using SML's regular reference
448 :     cells, so the :== and !! notation has been deprecated. All of these
449 :     changes will appear in the 110.64 user guide for ml-lpt.
450 :    
451 :     The ml-antlr tool now does much more checking of specifications, and
452 :     its error messages have been greatly improved. There has also been
453 :     some work on the error repair process for generated parsers, but this
454 :     will be further improved in 110.64.

460 :     Description:
461 :    
462 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
463 :     Significant changes in FLINT and the front end, mostly having to do
464 :     with a reorganized system for handling primops. Various bug fixes
465 :     and improvements in printing signatures.

491 :    
492 :     More Basis fixes: The Char.fromString (etc.) functions did not handle

574 :     Description:
575 :    
576 :     Added preliminary support in MLRISC for Staged Allocation, a technique
577 :     for specifying calling conventions (see
578 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
579 :     Initially, we plan to use this code to generate C calls for the AMD64.
580 :    
581 :     The staged allocation code base resides in MLRISC/staged-allocation,
582 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

602 :    
603 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
604 :     of the range -128 ... 127. I've changed the code so that the range
605 :     check is disabled. Only the low order 8 bits of the immediate operand

647 :     Description:
648 :    
649 :     Brought ml-lpt manual up-to-date with the code. Many minor
650 :     improvements to the tools, and a few minor bugfixes. Prepared
651 :     ml-lpt-lib for integration with new UTF8 structure. Changed
652 :     the interface for creating streams in ml-ulex (we now support
653 :     stream creation from several kinds of sources). Overall, the
654 :     tools are now quite stable, and their interfaces are unlikely to
655 :     change in a way that would break compatibility. More work,
656 :     however, is needed in the documentation.

661 :     Description:
662 :    
663 :     Implemented library installer. Moved CM plugin code for
664 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
665 :     their respective trees. Implemented CM plugin for ml-ulex
666 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
667 :     and ml-antlr.
668 :    
669 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
670 :     CM tools. (It turns out to be too messy to do otherwise because
671 :     there is too much code that during installation relies on the presence
672 :     of these tools -- resulting in a tricky ordering problem.)

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

751 :     Date: 2006/12/08 09:50:00 CST
752 :     Description:
753 :    
754 :     Added code to CM's "standard shell tool" implementation which
755 :     causes it to tolerate (with a warning) the situation where the shell
756 :     command fails (e.g., due to the shell command's non-existence)
757 :     as long as all target files exist.
758 :    
759 :     This makes it possible to, e.g., build ml-yacc from sources even if
760 :     svn checkout messed up the time stamps on files in such a way that
761 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
762 :     be needed to re-process yacc.grm, but obviously it might not yet be
763 :     available at that time.)

803 :     Description:
804 :    
805 :     New working release (110.60). NEW BOOTFILES!
806 :    
807 :     This is the first subversion-hosted release. There are also changes
808 :     to the directory layout. Here is a table:
809 :    
810 :     (All pathnames are relative to the SML/NJ "root" directory.)
811 :    
812 :     config -> config
813 :    
814 :     src/cm -> base/cm
815 :     src/compiler -> base/compiler
816 :     src/runtime -> base/runtime
817 :     src/system -> base/system
818 :    
819 :     src/cm/pgraph -> pgraph
820 :    
821 :     src/READMES -> base/READMES
822 :     src/$notefile -> base/NOTES/$notefile
823 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
824 :     MACOSXINSTALL WININSTALL
825 :    
826 :     src/smlnj-lib -> smlnj-lib
827 :     src/MLRISC -> MLRISC
828 :     ckit -> ckit
829 :     src/cml -> cml
830 :     src/eXene -> eXene
831 :     src/heap2asm -> heap2asm
832 :     src/lexgen -> lexgen
833 :     src/ml-burg -> ml-burg
834 :     src/ml-lex -> ml-lex
835 :     src/ml-yacc -> ml-yacc
836 :     src/ml-nlffi-lib -> nlffi/lib
837 :     src/ml-nlffigen -> nlffi/gen
838 :     src/smlnj-c -> smlnj-c
839 :     src/tools/TraceDebugProf -> trace-debug-profile
840 :    
841 :     In addition, there is also a new
842 :    
843 :     ml-lpt
844 :    
845 :     directory containing two new program generator tools: ml-ulex and
846 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
847 :     LL(k) parser generator). These tools are currently "beta-quality"
848 :    
849 :     The latest versios of the sources can now be obtained anonymously
850 :     via subversion. For this, it is useful to first check out
851 :    
852 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
853 :    
854 :     and put the resulting directory on your shell's PATH. This provides
855 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
856 :     and refresh-all.sh.
857 :    
858 :     To create a freshly checked-out copy of the sources, do
859 :    
860 :     checkout-all.sh [dir]
861 :    
862 :     where dir is the optional SML/NJ root directory (default is ".").
863 :    
864 :     This creates the above directory layout. Each subdirectory of
865 :     the root is under individual subversion control. The stat-all.sh
866 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
867 :     each of these subtrees.

871 : blume 2155 Date: 2006/11/02 12:20:00 CST
872 :     Description:
873 :    
874 :     Reorganized directory layout.
875 :    
876 :     This is a temporary solution, more reorganization is to come.
877 :    
878 :     The basic idea is to have a number of toplevel trees, each corresponding
879 :     to a well-defined part of the overall system. Each part can be
880 :     maintained individually, even in separate source repositories,
881 :     although currently we still serve everything out of the main
882 :     smlnj-gforge tree.
883 :    
884 :     Installer and and scripts have been updated to reflect the new
885 :     layout. The installer (base/src/system/smlnj/installer) is now
886 :     "scriptable" to avoid burning too much knowledge about the
887 :     layout into SML source code. The main script used by the installer
888 :     is in config/actions.
889 :    
890 :     The main change is that many of the subdirectories of what used to
891 :     be known as "src" have moved to the toplevel. The "src" directory
892 :     itself has moved down into a subtree called "base". (We may eventually
893 :     get rid of the extra level of indirection represented by "src".)
894 :    
895 :     The layout is now as follows:
896 :    
897 :     toplevel tree name | default repository
898 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
899 :     -------------------+----------------------------------------------------
900 :     config | $gf/config/trunk
901 :     |
902 :     base | $gf/sml/trunk
903 :     |
904 :     smlnj-lib | $gf/smlnj-lib/trunk
905 :     MLRISC | $gf/MLRISC/trunk
906 :     |
907 :     ml-yacc | $gf/ml-yacc/trunk
908 :     ml-lex | $gf/ml-lex/trunk
909 :     ml-burg | $gf/ml-burg/trunk
910 :     lexgen | $gf/lexgen/trunk
911 :     heap2asm | $gf/heap2asm/trunk
912 :     |
913 :     cml | $gf/cml/trunk

916 :     nlffi | $gf/nlffi/trunk
917 :     |
918 :     smlnj-c | $gf/smlnj-c/trunk
919 :    
920 :     In $gf/admin there are a few useful shell scripts for checking out
921 :     and maintaining the entire collection of trees:
922 :    
923 :     admin/checkout-all.sh [dir]
924 :     -- optionally creates dir and checks out all trees from their
925 :     default repositories; if dir is missing, checkout into .
926 :     admin/refresh-all.sh [dir]
927 :     -- looks at all trees (from the above list) in dir (default: .)
928 :     and runs "svn update" if the tree exists and is under
929 :     subversion control;
930 :     non-existing or non-subversion trees are skipped
931 :     admin/stat-all.sh [dir]
932 :     -- like refresh-all.sh, but runs "svn stat" instead

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

1080 :     Hooked code for Darwin-specific Intel ABI into main compiler.
1081 :     (This is a temporary solution which relies on the fact that the

1112 :     Description:
1113 :    
1114 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1115 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1116 : blume 2155 at the time when config/preloads is processed, the library has to
1117 : mblume 1878 be referred to by another name. In 110.57 this would be
1118 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1119 :     to be valid as well.)

1175 :     Description:
1176 :    
1177 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1178 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1179 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1180 :     it. Instead, it has the status of "user code", so it should use
1181 :     $/basis.cm to refer to the Basis library. (At least that's true for
1182 :     the purpose of bootstrapping the previous change. In the future it
1183 :     might make sense to have versiontool.cm refer to
1184 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1185 :     compiler itself uses.)
1186 :    
1187 :     Also patched src/system/testml to have it activate those extra anchor
1188 :     bindings in config/extrapathconfig.

1193 :     Tag: blume-22051115-libraries
1194 :     Description:
1195 :    
1196 :     This change affects the way the following libraries are tied into
1197 :     the system:
1198 :    
1199 :     $/basis.cm
1200 :     $/smlnj-lib.cm
1201 :     $/pp-lib.cm
1202 :     $/controls-lib.cm
1203 :     $/html-lib.cm
1204 :     $/ml-yacc-lib.cm
1205 :    
1206 :     These libraries are now internally (as seen from the source code
1207 :     of the implementation itself) known by the following names:
1208 :    
1209 :     $smlnj/basis/basis.cm
1210 :     $smlnj/smlnj-lib/smlnj-lib.cm
1211 :     $smlnj/smlnj-lib/pp-lib.cm
1212 :     $smlnj/smlnj-lib/controls-lib.cm
1213 :     $smlnj/smlnj-lib/html-lib.cm
1214 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1215 :    
1216 :     This makes it possible to work with code that requires different
1217 :     versions of these libraries, and which refers to these libraries using
1218 :     their "default" names (i.e., the first set of names above). In other
1219 :     words, one can un-define or re-define those default names without
1220 :     compromising the proper functioning of the compiler itself.
1221 :    
1222 :     A similar procedure had already been performed for several of the
1223 :     MLRISC libraries that are linked into the compiler. I did some
1224 :     cleanup on this code.
1225 :    
1226 :     A new file in the config directory (named extrapathconfig) is
1227 :     responsible for setting up path anchors that the compiler itself does
1228 :     not need, but that are typically required by user code.

1407 :     Tag: blume-20050516-redump-heap
1408 :     Description:
1409 :    
1410 :     Added mechanism for re-creating a heap file for the interactive system
1411 :     after configuration variables have been changed.
1412 :    
1413 :     CM.redump_heap : string -> unit
1414 :    
1415 :     This is much like SMLofNJ.exportML, but starting from the resulting
1416 : blume 2155 heap does not return to the caller of CM.redump_heap but
1417 : mblume 1792 restarts the interactive system from scratch. The original call of
1418 :     CM.redump_heap does not return but ends the interactive session.
1419 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1420 :    
1421 :     Internally, redump_heap winds the dynamic execution context back to
1422 :     the point where the original heap image was created and re-executes
1423 :     the heap image generation code in the boot code.

1539 :     Tag: blume-20050114-heap2exec
1540 :     Description:
1541 :    
1542 :     Implemented new (but still experimental) heap2exec facility. This is
1543 :     tested under Mac OS X and should work under Linux (will test shortly).
1544 :     It will probably also work on the Sparc (will test some time later).
1545 :    
1546 :     - removed old "HACKED_STANDALONE" hack from runtime
1547 :    
1548 :     To be able to test this, uncomment the request for "heap2asm" in
1549 :     config/targets prior to installation. (Notice that this is different
1550 :     from "heap2exec" mentioned below. Not a typo.)
1551 :    
1552 :     To perform an actual test, run the command
1553 :    
1554 :     $ bin/heap2exec heapfile execfile
1555 :    
1556 :     (You can put heap2exec on your shell's path.)
1557 :    
1558 :     For example, run
1559 :    
1560 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1561 :    
1562 :     This will create a standalone executable called "mly" which you can
1563 :     then invoke directly as a command.

1589 :     data structure access seems to work.)
1590 :    
1591 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1592 :     (On the Mac, it is big-endian. And that's currently our only
1593 :     PPC platform.)

1610 :    
1611 : blume 2155 The Unix I/O library of SML/NJ on cygwin does not understand

1708 :     Tag: blume-20041124-position
1709 :     Description:
1710 :    
1711 :     The compiler can now be compiled in a mode that makes structure Position
1712 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1713 :     for the time being.
1714 :    
1715 :     To enable 64-bit positions, use the following procedure:
1716 :    
1717 :     1. Start sml
1718 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1719 :     3. Type
1720 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1721 :     4. Run CMB.make() as usual.
1722 :    
1723 :     This is barely tested. The only test so far was a little SML program
1724 :     counting the number of characters in an 8-gigabyte file by
1725 :     reading it character-by-character. That test was successful.
1726 :    
1727 :     In support of 64-bit positions, a number of new functions have been
1728 :     added to the runtime system.

1768 :     Tag: blume-20041113-versiontool
1769 :     Description:
1770 :    
1771 :     - Stripped down the versiontool: It now only handles the version number.
1772 :     The date string is generated at bootstrap time (during makeml).
1773 :    
1774 :     - In a previous commit, fixed a minor issue with how polyequal is being
1775 :     translated. In particular, the code now "looks through" abstractions.
1776 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1777 :     more efficient code. Important examples for where this matters are
1778 :     the new int64 and word64 types.

1793 :     Description:
1794 :    
1795 :     All the pieces of Word64 are now there, with the exception of the
1796 :     conversions from and to LargeWord. (Eventually these need to be identities,
1797 :     but for the time being they don't even make sense because LargeWord is
1798 :     32-bit wide.)
1799 :    
1800 :     Also started to add similar support for Int64, but major pieces of that
1801 :     are still missing.

1806 :     Tag: blume-20041111-word64
1807 :     Description:
1808 :    
1809 :     Structure Word64 is now (almost) complete, word literals and patterns
1810 :     seem to work. There are a few odd pieces missing. In particular,
1811 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1812 :     at the moment.
1813 :    
1814 :     Making Word64 official would mean that LargeWord becomes Word64. But
1815 :     this requires extreme care because most word-word conversions have to
1816 :     go through LargeWord, so making a mistake means loss of efficiency or
1817 :     worse. Eventually there will be a solution similar to (but actually
1818 :     simpler than) what I did with IntInf.

1850 :     - Changend config/srcarchiveurl from a file just

1853 :     - Made corresponding changes to config/install.sh and config/unpack.
1854 :     - Default contents of config/srcarchiveurl uses $VERSION and
1855 :     normally does not have to be edited to reflect a version change.
1856 :    
1857 :     (As a result, a version change can be done by just editing
1858 :     config/version, the rest is now automatic.)

1898 :     Tag: blume-20041020-standalone-backtrace
1899 :     Description:
1900 :    
1901 :     Added a mechanism for getting back-trace information from standalone
1902 :     programs. Here is how it works:
1903 :    
1904 :     1. The part of the program from which you want to get backtrace
1905 :     information (usually the whole program) should be wrapped with
1906 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
1907 :     main program could be modified from something like
1908 :    
1909 :     fun main (pgm, args) = ...
1910 :    
1911 :     to
1912 :    
1913 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1914 :    
1915 :     2. To be able to access BackTrace.monitor, you have to add
1916 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
1917 :     main function.
1918 :    
1919 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1920 :     CM might have created in the past for your project).
1921 :    
1922 :     4. Build the system using this command line:
1923 :    
1924 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1925 :     myprog.cm MyProg.main myprog
1926 :    
1927 :     instead of the usual
1928 :    
1929 :     ml-build myprog.cm MyProg.main myprog
1930 :    
1931 :     I changed a library name:
1932 :    
1933 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1934 :    
1935 :     New libraries:
1936 :    
1937 :     $smlnj-tdp/back-trace.cm
1938 :     -- when loaded causes the back-trace plugin to be installed
1939 :     $smlnj-tdp/coverage.cm
1940 :     -- when loaded causes the coverage plugin to be installed

1955 :     Tag: blume-20041015-coverage
1956 :     Description:
1957 :    
1958 :     * Test coverage tool added!
1959 :     * Further reorganization of tracing-, debugging-, and profiling support:
1960 :    
1961 :     - moved original BTImp -- now called BackTrace -- into a separate
1962 :     library called $/trace-debug-profile.cm
1963 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
1964 :     - only the instrumentation mechanism is now left in the compiler proper
1965 :     - BackTrace module is a plugin which is NOT plugged in by default
1966 :     - Coverage module is another such plugin
1967 :    
1968 :     To get the benefits of any of these plugin modules, the code in
1969 :     question must be compiled with tdp instrumentation turned on. This
1970 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
1971 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1972 :    
1973 :     Plugins are selected at link time. (Pre-compiled instrumented code
1974 :     can be re-loaded with different plugins in effect.) When an
1975 :     instrumented module is linked, whatever plugins are at that time
1976 :     enabled will come into effect for that module.
1977 :    
1978 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
1979 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
1980 :     To enable the coverage plugin, load the same library and invoke
1981 :     Coverage.install().
1982 :    
1983 :     Back-traces are generated automatically on uncaught exceptions and
1984 :     when the code in question explicitly invokes BackTrace.trigger().
1985 :    
1986 :     Coverage (and execution frequency-) information must be queried
1987 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2008 :

2010 :     instrumentation for other purposes. "TDP" stands for
2011 :     Trace/Debug/Profile.
2012 :    
2013 :     The control flag controlling whether instrumentation is on or off is now

2041 :    
2042 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool

2104 :     Tag: blume-20040929-autoversion
2105 :     Description:
2106 :    
2107 :     Implemented some CM magic to have
2108 :     file src/compiler/TopLevel/main/version.sml
2109 :     generated automagically.
2110 :     The version is taken from two files: config/version and config/release.
2111 :     The first is expected to contain a two-part version number such as 110.49.
2112 :     The second should contain a single number, but it may be missing.
2113 :    
2114 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2115 :     time the version tool is loaded (which is the first time you say CMB.make),
2116 :     then the tool will increment the value stored in config/release every
2117 :     time CMB.make is invoked.
2118 :    
2119 :     The binfile format is now insensitive to anything beyond the first
2120 :     two components of a version number, so bumping the release does not render
2121 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2122 :     during development without invalidating existing binfiles.
2123 :    
2124 :     In any case, every CMB.make updates the date information in version.sml.
2125 :     (This is the date that is printed in the banner.)

2132 :    
2133 :     Some cleanup of the controls code.

2137 : mblume 1633 Date: 2004/09/27 22:08:00 CDT
2138 :     Tag: blume-20040927-controls
2139 :     Description:
2140 :    
2141 :     Added two pieces of functionality to the Controls interface:
2142 :    
2143 :     1. val save'restore: 'a control -> unit -> unit
2144 :    
2145 :     grabs the current value of the control in stage 1 and restores it
2146 :     in stage 2.
2147 :    
2148 :     2. val set' : 'a control * 'a -> unit -> unit
2149 :    
2150 :     stores the given value into the control in stage 2 (i.e., delayed)
2151 :     but does all error checking in stage 1.
2152 :     (This is for string controls that need to do parse their argument --
2153 :     something that might fail. In some cases, notably in CM, one
2154 :     already knows the intended argument but wants to delay the actual
2155 :     assignment until a time when error recovery would be more difficult.)
2156 :    
2157 :     Changed the handling of controls in tool arguments to classes "sml" and
2158 :     "lazysml":
2159 :     - use Controls.save'restore as a more robust way of restoring the
2160 :     old value (in particular: without having to re-parse the string)
2161 :     - use controls to handle the "overload" keyword in the init group
2162 :     (I believe this change actually fixes a long-standing obscure bug.)

2166 : mblume 1632 Date: 2004/09/27 17:00:00 CDT
2167 :     Tag: blume-20040927-lazysml
2168 :     Description:
2169 :    
2170 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2171 :     difference to "sml" is that compilation is done with Control.lazysml
2172 :     set to true. A source of class "lazysml" is automatically recognized
2173 :     by a file name suffix of ".lml".
2174 :    
2175 :     In addition to the above feature, the original class "sml" now also
2176 :     supports a tool argument "lazy" which has the same effect. As a
2177 :     result, the following three lines are equivalent:
2178 :    
2179 :     foo.sml : lazysml
2180 :     foo.sml : sml (lazy)
2181 :     foo.sml (lazy)
2182 :    
2183 :     The setting goes into effect both during parsing and during
2184 :     compilation. The original setting is restored right after parsing and
2185 :     after compilation, respectively.
2186 :    
2187 :     In addition to all the above, there is also a general mechanism to set
2188 :     ANY of the "controls" that are available at the command line via
2189 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2190 :     apply as well. (In fact, "lazy" is implemented as a special case of
2191 :     the general mechanism.)
2192 :    
2193 :     The .cm file syntax uses a new keyword tool argument called "with".
2194 :     There are several ways of indicating the desired settings:
2195 :    
2196 :     foo.sml (with:parser.quotations=true)
2197 :     foo.sml (with:(name:parser.quotations value:true))
2198 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2199 :     foo.sml (with:(name1=value1 name2=value2 ...))
2200 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2201 :    
2202 :     etc.
2203 :    
2204 :     Another possible abbreviation is to leave out the =v or value:v part
2205 :     if the name refers to a boolean control (in which case the value is
2206 :     taken to be true). Thus, one could get lazy sml also by saying:
2207 :    
2208 :     foo.sml (with:parser.lazy-keyword=true)
2209 :     foo.sml (with:parser.lazy-keyword)
2210 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2211 :     foo.sml (with:(name:parser.lazy-keyword))

2508 :     Description:
2509 :    
2510 :     - use paramAlloc to report c-calls with too many arguments
2511 :     (for PPC version where parameter area is pre-allocated)
2512 :     - added ccall_maxargspace to machspec (to implement the above)
2513 :     - made "make" commend in CM's "make" tool configurable
2514 :     - added option (default: on) for passing the name of the SML/NJ's "bin"
2515 :     directory to "make"; the call looks like this:
2516 :    
2517 :     make <options> SMLNJ_BINDIR=<dir> <target>
2518 :    
2519 :     This can be used by the Makefile to, e.g., pick the "right" version

2529 :     NLFFI under Mac OS X now working (sort of). This is largely untested,
2530 :     though.
2531 :    
2532 :     Note: 1. You have to make a new, clean build of the runtime system.
2533 :     2. There are new BOOTFILES, you have to use them!
2534 :     (Doing the bootstrap process yourself would be *very* painful!
2535 :     If you absolutely have to do it, build the system under
2536 :     a different architecture and then cross-compile.)
2537 :    
2538 :     Version bumped to 110.46.1 to account for runtime data format changes.

2562 :     Tag: blume-20040617-timer-unix
2563 :     Description:
2564 :    
2565 :     Changed the interface of structures Timer and Unix to match the most
2566 :     recent Basis spec.
2567 :    
2568 :     In the case of Unix there still seems to be an open/weird issue:
2569 :    
2570 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2571 :     fresh streams whenever they are called -- as opposed to have them
2572 :     return the same stream every time. This design is supposed to
2573 :     prevent space leaks caused by proc values hanging on to streams.
2574 :    
2575 :     The reap function, on the other hand, is supposed to close the
2576 :     streams. This cannot be done without having a handle on the
2577 :     stream in proc after all...
2578 :    
2579 :     I took the liberty to implement the following stopgap solution:
2580 :    
2581 :     The proc value hangs on to the most recently created stream(s).
2582 :     Reap closes those. If either or both of the two streams hadn't
2583 :     been created at all yet, then reap will close the corresponding
2584 :     file descriptors directly.
2585 :    
2586 :     PS: I don't understand the original space leak argument anymore. If
2587 :     a proc hangs on to the imperative stream, then I/O operations on those
2588 :     will advance the state of the cached stream and avoid the space leak.

2601 :     Tag: blume-20040525-group-owner
2602 :     Description:
2603 :    
2604 :     CM now ignores (but still accepts) the "owner" information in group
2605 :     descriptions. The owner of a group is its next enclosing
2606 :     library. Each group must have a unique owner. (There is a virtual
2607 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2608 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2609 :     and CM would check that such a declaration is correct. The new scheme
2610 :     is to have CM check that for each group there is precisely one owning
2611 :     library.
2612 :    
2613 :     The advantage of the new scheme is that the programmer no longer needs
2614 :     to maintain the somewhat annoying owner information. The downside is
2615 :     that CM cannot enforce the ownership rule across multiple runs of
2616 :     CM.make. Fortunately, enclosing the same group in two different
2617 :     libraries A and B which are not part of the same program does not
2618 :     cause real problems.

2637 :     Description:
2638 :    
2639 :     Arranged for ml-build to clean up after itself a little bit better.
2640 :     The script generates a temporary SML source file and compiles it using
2641 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
2642 :     gets rid of those at the end, so they don't accumulate under .cm.
2643 :    
2644 :     This required a minor change to install.sh because the name of the
2645 :     metadata directory (default: .cm) is actually configurable at
2646 :     installation time.

2662 :    
2663 :     Added previously missing support for many socket-related functions
2664 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
2665 :     for the voluminous patch!
2666 :    
2667 :     (I have not tested this patch under win32 yet.)
2668 :    
2669 : mblume 1490 Here is David's e-mail:
2670 :    
2671 :     Hi,
2672 :    
2673 :     Attached to this email you find a diff against sml/nj 110.45
2674 :     that will enable socket support under Windows.
2675 :    
2676 :     To apply the patch (using unix or cygwin)
2677 :     1) gunzip runtime.diff.gz
2678 :     2) "cd" into "src/runtime" in the source tree of a fresh
2679 :     110.45 installation.
2680 :     3) patch -p 1 < [your/path/to]runtime.diff
2681 :    
2682 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2683 :     I only ran a few tests for basic socket client functionality
2684 :     (which worked fine). Especially the functions that use ioctl
2685 : mblume 1490 are not tested at all and might not work (see below).
2686 :    
2687 :     I implemented this since we want to move to a newer version of sml/nj
2688 :     but need socket support in order to use it. This is the first time I
2689 :     even had a look at the sml/nj source, so please review my changes
2690 :     before making this part of the distribution! Here are a few issues
2691 : blume 2155 that I think might be better for someone to solve who is more
2692 : mblume 1490 familiar with the sml/nj source (and socket programming):
2693 :    
2694 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2695 :     exception since I could not figure out what the windows equivalent
2696 :     of these functions is
2697 :    
2698 :     - In sockets-osdep.h there are a some #include statements that are
2699 :     only used in a few files that include sockets-osdep.h
2700 :    
2701 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2702 :     does not process its return value since I don't know how to
2703 :     report an error upwards.
2704 :    
2705 :     - It would probably be good to have a call to WSACleanup() when
2706 : blume 2155 the library is unloaded (if there is such a possibility).
2707 : mblume 1490 Otherwise I think Windows will take care of this automatically
2708 :     when the process finishes.
2709 :    
2710 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2711 :     no idea if that is actually the proper replacement on Windows.
2712 :    
2713 :     - All these issues are marked in the code by "FIXME" comments.
2714 :    
2715 : blume 2155 We use sml/nj extensively in our products and are quite happy
2716 :     with it. I hope this contribution will help you.
2717 : mblume 1490
2718 :     Keep up the good work!

2941 :     Description:
2942 :    
2943 :     I modified the read-eval-print loop so that the autoloader gets
2944 :     invoked whenever the prettyprinter tries to look up a symbol that
2945 :     is not currently defined in the toplevel environment but which
2946 :     appears in CM's autoload registry. As a result, we see far fewer of
2947 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
2948 :    
2949 :     In addition to this I tried to clean up some pieces of the Basis
2950 :     implementation (e.g., Socket, Word8Array) in order to prevent other
2951 :     instances of these ?.Foo.Bar.xxx names from being printed.
2952 :    
2953 :     The mechanism that picks names for types still needs some work, though.
2954 :     (Right now it seems that if there is a type A.t which is defined to
2955 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
2956 :     "?.B.u" although the perhaps more sensible solution would be to use
2957 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
2958 :     a chain of DEFtycs not farther than there are corresponding toplevel
2959 :     names in the current environment.)

2965 :     Description:
2966 :    
2967 :     Another installer tweak: All the ML code for the installer is now
2968 :     compiled during CMB.make and put into a little library called
2969 :     $smlnj/installer.cm. The installation then simply invokes
2970 :    
2971 :     sml -m $smlnj/installer.cm
2972 :    
2973 :     and everything happens automagically.
2974 :    
2975 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
2976 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
2977 :     and BINDIR.
2978 :    
2979 :     The new scheme guarantees that the ML code responsible for the installation
2980 :     is in sync with the APIs of the main system. Also, the installer is
2981 :     somewhat faster because the installer script is precompiled.

2998 :     Tag: blume-20030924-sockets
2999 :     Description:
3000 :    
3001 :     1. Fixed SOCKET API and implementation to match Basis spec.
3002 :     This required changing the internal representation of sockets to one
3003 :     that remembers (for each socket file descriptor) whether it is currently
3004 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3005 :     call is made only if the state actually needs to change).
3006 :    
3007 :     2. OS-specific details of sockets were moved into separate files, thus
3008 :     making it possible to unify the bulk of the socket implementations
3009 :     between Unix and Win32.
3010 :    
3011 :     3. CML's socket API changed accordingly.
3012 :     (Note that we need to remove non-blocking functions from this API
3013 :     since they are redundant in the case of CML!)
3014 :    
3015 :     4. CML's socket implementation now makes use of non-blocking functions
3016 :     provided by Basis, thus removing all OS-dependent code from this part
3017 :     of CML.
3018 :    
3019 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3132 :     Description:
3133 :    
3134 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3135 :     Modified config/install.bat to take advantage of it. Also modified
3136 :     config/install.sh (and called it config/new-install.sh) to take advantage
3137 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3138 :     independent.)
3139 :    
3140 :     The installer can now install everything under Win32

3142 :    
3143 :     Other changes:
3144 :    
3145 :     - made CML compile again under Win32
3146 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3147 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3148 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3149 :     same as type int; under Win32 it isn't
3150 :     - fixed some slice-related problems in the win32-specific parts of CML
3151 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3152 :     (under Win32, the volume name is case-insensitive, and the
3153 :     OS.Path code compares volume names for equality)

3170 : mblume 1350 Description:
3171 :    
3172 :     1. Changed interface to vectors and arrays in Basis to match
3173 :     (draft) Basis spec.
3174 :     2. Added signatures and implementations of slices according to
3175 :     Basis spec.
3176 :     3. Edited source code throughout the system to make it compile again
3177 :     under 1. and 2. (In some cases code had to be added to have it
3178 :     match the new signatures.)
3179 :     4. MLRISC should be backward-compatible: the copies of the originals
3180 :     of files that needed to change under 3. were retained, the .cm files
3181 :     check the compiler version number and use old versions when
3182 :     appropriate.
3183 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3184 :     dirstream -> string option (in accordance with Basis spec).
3185 :     6. When generating code that counts lines, ml-lex used function
3186 :     CharVector.foldli, taking advantage of its old interface.
3187 :     This has been replaced with the corresponding code from
3188 :     CharVectorSlice. (html-lex must be re-lexed!)
3189 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3190 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3191 :     8. Removed temporary additions (fromInternal, toInternal) from the
3192 :     (now obsolete) IntInf in smlnj-lib/Util.
3193 :     9. Cleaned up structure Byte.
3194 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3195 :     Cleaned/corrected implementation of Date.
3196 :     (Still need to check for correctness; implement better canonicalizeDate.)
3197 :     11. Added "scan" to signature IEEE_REAL.
3198 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3199 :     mod and rem when second operand is 2 (for parity checks).]
3200 :     13. Changed representation of type Time.time, using a single IntInf.int
3201 :     value counting microseconds. This considerably simplified the
3202 :     implementation of structure Time. We now support negative time
3203 :     values; scan and fromString handle signs.
3204 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3205 :     ArraySlice).

3211 :     Description:
3212 :    
3213 :     This is a major update which comes with a version number bump
3214 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3215 :     and an implementation of IntInf in the Basis.
3216 :    
3217 :     There are a fairly large number of related changes and updates throughout
3218 :     the system:
3219 :    
3220 :     Basis:
3221 :     - Implemented IntInf.
3222 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3223 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3224 : mblume 1347 - Added FixedInt as a synonym for Int32.
3225 :    
3226 :     compiler:
3227 :     * Added support for a built-in intinf type.
3228 :     - literals
3229 :     - pattern matching
3230 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3231 :     - overloading on literals and operations
3232 :    
3233 :     This required adding a primitive type intinf, some additional
3234 :     primops, and implementations for several non-trivial intinf
3235 :     operations in Core. (The intinf type is completely abstract
3236 :     to the compiler; all operations get delegated back to the Core.)
3237 :    
3238 :     * Intinf equality is handled by polyequal. However, the compiler
3239 :     does not print its usual warning in this case (since polyequal
3240 :     is the right thing to do there).
3241 :    
3242 :     * Improved the organization of structure InlineT.
3243 :    
3244 :     * A word about conversion primops:
3245 :     If conversions involving intinf do not cancel out during
3246 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3247 : mblume 1347 Since all core access must be resolved already during the FLINT
3248 :     translate phase, it would be too late a the time of CPS contract
3249 : mblume 1348 to add new Core calls. For this reason, conversion primops
3250 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3251 :     they are supposed to convert, and 2. the Core function that
3252 :     can help with this conversion if necessary. If CPS contract
3253 : mblume 1348 eliminates a primop, then the associated Core function becomes
3254 :     dead and goes away. Intinf conversion primops that do not get
3255 :     eliminated by CPS contract get rewritten into calls of their
3256 :     core functions by a separate, new phase.
3257 : mblume 1347
3258 :     interactive system:
3259 :     - Control.Print.intinfDepth controls max length of intinf constants
3260 :     being printed. (Analogous to Control.Print.stringDepth.)
3261 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3262 :     duplicates; replaced some of the code with code that makes better
3263 :     use of library functionality.
3264 :    
3265 :     CM:
3266 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3267 :     are no longer silent.
3268 :    
3269 :     CKIT:
3270 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3271 :     in favor of LargeInt -- which is now the same as IntInf.
3272 :     CKIT-knowledgable people should check whether this is what's
3273 :     intended and otherwise change things back to using Int32 or
3274 :     FixedInt.
3275 :    
3276 :     Throughout the code:

3285 :     Description:
3286 :    
3287 :     Merging changes from the mcz-branch development branch into trunk.
3288 :     These changes involve replacement of the emulated old prettyprinter
3289 :     interface with direct use of the SML/NJ Lib PP library, and fixing
3290 :     of a couple of bugs (895, 1186) relating to error messages. A new
3291 :     prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
3292 :     has been added.

3297 :     Tag: blume-20030811-windows
3298 :     Description:
3299 :    
3300 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3301 :    
3302 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3303 :    
3304 :     This patch restores SML/NJ's ability to run under win32. There are a
3305 :     number of changes, including fixes for several bugs that had gone
3306 :     unnoticed until now:
3307 :    
3308 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3309 :     trying to run the win32 version from within cygwin.)
3310 :    
3311 :     - There are a number of simple .bat scripts that substitute for their
3312 :     corresponding Unix shell-scripts. (See below.)
3313 :    
3314 :     - The internals of ml-build have been modified slightly. The main
3315 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3316 :     using OS.Process.system, the ML process delegates this task back
3317 :     to the script. Otherwise problems arise in mixed environments such
3318 :     as Cygwin where scripts look and work like Unix scripts, but
3319 :     where OS.Process.system cannot run them.
3320 :    
3321 :     - In CM, the srcpath pickler used native pathname syntax -- which
3322 :     is incorrect in the case of cross-compilation. The new pickle format
3323 :     is independent of platform-specific naming conventions.
3324 :    
3325 :     - Path configuration files (such as lib/pathconfig) can now choose
3326 :     between native and standard syntax. Placing a line of the form
3327 :    
3328 :     standard!
3329 :    
3330 :     into the file causes all subsequent paths to be interpreted using
3331 :     CM standard pathname syntax (= Unix conventions); a line
3332 :    
3333 :     native!
3334 :    
3335 :     switches back to native style. This was needed so that
3336 :     path config files can be written portably, see src/system/pathconfig.
3337 :    
3338 :     - Runtime system:
3339 :    
3340 :     - win32-filesys.c: get_file_time and set_file_time now
3341 :     access modification time, not creation time.
3342 :    
3343 :     - I/O code made aware of new array representation.
3344 :    
3345 :     - Bug fixes in X86.prim.masm.
3346 :    
3347 :     - src/system/makeml made aware of win32. (For use under cygwin
3348 :     and other Unix-environments for windows.)
3349 :    
3350 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3351 :     which caused BinIO.inputAll to fail consistently.
3352 :    
3353 :     .bat scripts:
3354 :    
3355 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3356 :    
3357 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3358 :     applications (sml, ml-yacc, ml-lex).
3359 :     - ml-build.bat: analogous to ml-build.
3360 :     - config\install.bat: Analogous to config/install.sh. This requires
3361 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3362 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3363 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3364 :     and the bootfile hierarchy must have been unpacked under
3365 :     sml.boot.x86-win32.
3366 :     The script is very primitive and does a poor job at error checking.
3367 :     It only installs the base system, ml-lex, and ml-yacc. No other
3368 :     libraries are being installed (i.e., you get only those that
3369 :     are part of the compiler.)
3370 :     - link-sml.bat: analogous to .link-sml, but not currently used
3371 :    
3372 :     Unrelated bug fixes:
3373 :    
3374 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3375 :     types.
3376 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3377 :     otherwise.)

3401 :     Description:
3402 :    
3403 :     Two changes:
3404 :    
3405 :     1. Added a flag for controlling whether non-exhaustive bindings will
3406 :     be treated as errors (default is false).
3407 :     2. Cleaned up the *entire* source tree so that CMB.make goes through
3408 :     without a single non-exhaustive match- or bind warning.

3413 :     Tag: blume-20030517-absyn
3414 :     Description:
3415 :    
3416 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3417 :    
3418 :     This mainly affects the quality of error messages. However, some
3419 :     of the code is now more straightforward than before. (Treatment of
3420 :     the above four constructs in translate.sml is much simpler than
3421 :     the "macro-expansion" that was going on before. Plus, the mach-
3422 :     compiler no longer gets invoked just to be able to compile an
3423 :     if-expression.)
3424 :    
3425 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3426 :     interactive loop.

3432 :     Description:
3433 :    
3434 : blume 2155 Ported the runtime system to cygwin, which uses the unix
3435 : allenleung 1327 x86-unix bin files. Missing/buggy features:
3436 :    
3437 : blume 2155 o getnetbyname, getnetbyaddr: these functions seem to be missing in
3438 : allenleung 1327 the Cygwin library.
3439 :     o Ctrl-C handling may be flaky.
3440 :     o Windows system calls and Windows I/O are not supported.
3441 :    
3442 :     A new set of binfiles is located at:
3443 :    
3444 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3445 :    
3446 :     This is only needed for bootstrapping the cygwin version of smlnj.
3447 :     Other x86 versions can use the existing binfiles.

3472 :     Description:
3473 :    
3474 :     Fixed a serious bug in the rewrite code for FP spilling/reloading that
3475 :     sent the RA into an infinite loop when floating point registers get
3476 :     spilled. (Because of this bug, e.g., nucleic stopped compiling between
3477 :     110.37 and 110.38.)
3478 :     There was another set of potential problems related to the handling of
3479 :     MLRISC annotations (but those did not yet cause real problems, apparently).

3485 :     Description:
3486 :

3488 :     This fixes the problem of CM getting confused by files that suddenly
3489 :     change their identity (e.g., by getting unlinked and recreated by some
3490 :     text editor such as vi). There might be a better/cheaper/cleaner way
3491 :     of doing this, but for now this will have to do.

3506 :    
3507 : blume 1282 In good old tradition, there has been a slight hiccup so that we have

3513 :     each other's way.
3514 :

3546 :     the entire tree to some other place and everything will "just work".

3603 :     Another small change is that ppDec tries to give more information

3605 :     broken in some mysterious way if the functor's body's signature
3606 :     has not been declared by ascription but gets inferred from the

3706 :     Description:
3707 :    
3708 :     0. John Reppy made several modifications to the SML/NJ library.
3709 :     In particular, there is a shiny new controls-lib.cm.
3710 :    
3711 :     1. Pushed new controls interface through compiler so that everything
3712 :     compiles again.
3713 :    
3714 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3715 :     SML/NJ library (so that CML compiles again).
3716 :    
3717 :     3. Modified init scripts because XXX_DEFAULT environment variables
3718 :     are no longer with us. (Boot-time initialization is now done
3719 :     using the same environment variables that are also used for
3720 :     startup-time initialization of controls.)

3726 :     Description:
3727 :    
3728 :     All pseudo-ops emitted before the first segment declaration
3729 :     such as TEXT, DATA, and BSS directives are assumed to be global
3730 :     declarations and are emitted first in the assembly file. This is
3731 :     useful in a number of situations where one has pseudo-ops that are not
3732 :     specific to any segment, and also works around the constraint that one
3733 :     cannot have client pseudo-ops in the TEXT segment.
3734 :    
3735 :     Because no segment is associated with these declarations it is
3736 :     an error to allocate any space or objects before the first segment
3737 :     directive and an exception will be raised. However, we cannot make
3738 :     this check for client pseudo-ops.
3739 :    
3740 :     These top level declarations are a field in the CFG graph_info.
3741 :     In theory you can continue to add to this field after the CFG has been
3742 :     built -- provided you know what you are doing;-)

3752 :     - Stopgap measure for bug recently reported by Elsa Gunter (ppDec).

3765 :     Description:
3766 :    
3767 :     Applied the following bugfix provided by Emden Gansner:
3768 :    
3769 :     Output is corrupted when outputSubstr is used rather than output.
3770 :    
3771 : blume 2155 The problem occurs when a substring
3772 : blume 1189
3773 :     ss = (s, dataStart, dataLen)
3774 :    
3775 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3776 :     avail bytes of s, starting at index dataStart, are copied into the
3777 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3778 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3779 :     starting this copy at index dataStart+avail in s, the current code
3780 : blume 1189 starts the copy at index avail.
3781 :    
3782 :     Fix:
3783 :     In text-io-fn.sml, change line 695 from
3784 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3785 : blume 2155 to
3786 : blume 1189 val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

3802 :     Description:
3803 :    
3804 :     Added full support for div/mod/rem/quot on the x86, using the machine
3805 :     instruction's two results (without clumsily recomputing the remainder)
3806 :     directly where appropriate.
3807 :    
3808 :     Some more extensive power-of-two support was added to the x86 instruction
3809 :     selector (avoiding expensive divs, mods, and muls where they can be
3810 :     replaced with cheaper shifts and masks). However, this sort of thing
3811 :     ought to be done earlier, e.g., within the CPS optimizer so that
3812 :     all architectures benefit from it.
3813 :    
3814 :     The compiler compiles to a fixed point, but changes might be somewhat
3815 :     fragile nevertheless. Please, report any strange things that you might
3816 :     see wrt. div/mod/quot/rem...

3822 :     Description:
3823 :    
3824 :     Fixed my broken div/mod logic. Unfortunately, this means that the

3826 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3827 :     The problem was with quotient = 0, because that alone does not tell
3828 :     us which way the rounding went. One then has to look at whether
3829 :     remainder and divisor have the same sign... :(

3837 :     Description:
3838 :    
3839 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
3840 :    
3841 :     Primops have changed. This means that the bin/boot-file formats have
3842 :     changed as well.
3843 :    
3844 :     To make sure that there is no confusion, I made a new version.
3845 :    
3846 :    
3847 :     CHANGES:
3848 :    
3849 :     * removed REMT from mltree (remainder should never overflow).
3850 :    
3851 :     * added primops to deal with divisions of all flavors to the frontend
3852 :    
3853 :     * handled these primops all the way through so they map to their respective
3854 :     MLRISC support
3855 :    
3856 :     * used these primops in the implementation of Int, Int32, Word, Word32
3857 :    
3858 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3859 :    
3860 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
3861 :    
3862 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3863 :     floating point
3864 :    
3865 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3866 :     and Real (but Real.abs maps to a separate floating-point-only primop)
3867 :    
3868 :    
3869 :     TODO items:
3870 :    
3871 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
3872 :     instructions because the machine instruction encoder cannot handle
3873 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
3874 :     REM in the first place, and REM is supported by the x86 machine coder.)
3875 :    
3876 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
3877 :     selection phase. (The two can be streamlined because the hardware
3878 :     delivers both quotient and remainder at the same time anyway.)
3879 :    
3880 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
3881 :     (Currently the behavior is inconsistent both across architectures and
3882 :     wrt. the draft Basis spec.)
3883 :    
3884 :     * Word8 should eventually be handled natively, too.
3885 :    
3886 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
3887 :     as if there currently is no execution path that could trigger it in
3888 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
3889 :     hold for things like multiplication and division.)

3894 :     Tag: blume-20020327-mlrisc-divisions
3895 :     Description:
3896 :    
3897 :     Added support for all four division operations (ML's div, mod, quot,
3898 :     and rem) to MLRISC. In the course of doing so, I also rationalized
3899 :     the naming (no more annoying switch-around of DIV and QUOT), by
3900 :     parameterizing the operation by div_rounding_mode (which can be either
3901 :     DIV_TO_ZERO or DIV_TO_NEGINF).
3902 :    
3903 :     The generic MLTreeGen functor takes care of compiling all four
3904 :     operations down to only round-to-zero div.
3905 :    
3906 :     Missing pieces:
3907 :    
3908 :     * Doing something smarter than relying on MLTreeGen on architectures
3909 :     like, e.g., the x86 where hardware division delivers both quotient and
3910 :     remainder at the same time. With this, the implementation of the
3911 :     round-to-neginf operations could be further streamlined.
3912 :    
3913 :     * Remove inlining support for div/mod/rem from the frontend and replace it
3914 :     with primops that get carried through to the backend. Do this for all
3915 :     int and word types.

3920 :     Tag: blume-20020325-divmod
3921 :     Description:
3922 :    
3923 :     I improved (hopefully without breaking them) the implementation of Int.div,
3924 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
3925 :     advantage of the following observations:
3926 :    
3927 :     Let q = x quot y r = x rem y
3928 :     d = x div y m = x mod y
3929 :    
3930 :     where "quot" is the round-to-zero version of integer division that
3931 :     hardware usually provides. Then we have:
3932 :    
3933 :     r = x - q * y where neither the * nor the - will overflow
3934 :     d = if q >= 0 orelse x = q * y then q else q - 1
3935 :     where neither the * nor the - will overflow
3936 :     m = if q >= 0 orelse r = 0 then r else r + y
3937 :     where the + will not overflow
3938 :    
3939 :     This results in substantial simplification of the generated code.
3940 :     The following table shows the number of CFG nodes and edges generated
3941 :     for
3942 :     fun f (x, y) = x OPER y
3943 :     (* with OPER \in div, mod, quot, rem *)

3985 :    
3986 :     1. Changes to FLINT primops:
3987 :    
3988 :     (* make a call to a C-function;
3989 :     * The primop carries C function prototype information and specifies
3990 :     * which of its (ML-) arguments are floating point. C prototype
3991 :     * information is for use by the backend, ML information is for
3992 :     * use by the CPS converter. *)
3993 :     | RAW_CCALL of { c_proto: CTypes.c_proto,
3994 :     ml_args: ccall_type list,
3995 :     ml_res_opt: ccall_type option,
3996 :     reentrant : bool
3997 :     } option
3998 :     (* Allocate uninitialized storage on the heap.
3999 :     * The record is meant to hold short-lived C objects, i.e., they
4000 : blume 2155 * are not ML pointers. With the tag, the representation is
4001 : leunga 1174 * the same as RECORD with tag tag_raw32 (sz=4), or tag_fblock (sz=8)
4002 :     *)
4003 : blume 2155 | RAW_RECORD of {tag:bool,sz:int}
4004 : leunga 1174 and ccall_type = CCALL_INT32 | CCALL_REAL64 | CCALL_ML_PTR
4005 :    
4006 :     2. These CPS primops are now overloaded:
4007 :    
4008 :     rawload of {kind:numkind}
4009 :     rawstore of {kind:numkind}
4010 :    
4011 :     The one argument form is:
4012 :    
4013 :     rawload {kind} address
4014 :    
4015 :     The two argument form is:
4016 : blume 2155
4017 : leunga 1174 rawload {kind} [ml object, byte-offset]
4018 :    
4019 :     3. RAW_CCALL/RCC now takes two extra arguments:
4020 :    
4021 :     a. The first is whether the C call is reentrant, i.e., whether
4022 :     ML state should be saved and restored.
4023 :     b. The second argument is a string argument specifying the name of
4024 :     library and the C function.
4025 :    
4026 :     These things are currently not handled in the code generator, yet.
4027 :    
4028 :     4. In CProto,
4029 :    
4030 : blume 2155 An encoding type of "bool" means "ml object" and is mapped into
4031 :     C prototype of PTR. Note that "bool" is different than "string",
4032 : leunga 1174 even though "string" is also mapped into PTR, because "bool"
4033 :     is assigned an CPS type of BOGt, while "string" is assigned INT32t.
4034 :    
4035 :     5. Pickler/unpicker
4036 :    
4037 :     Changed to handle RAW_RECORD and newest RAW_CCALL
4038 :    
4039 :     6. MLRiscGen,
4040 :    
4041 :     1. Changed to handle the new rawload/rawstore/rawrecord operators.
4042 :     2. Code for handling C Calls has been moved to a new module CPSCCalls,
4043 :     in the file CodeGen/cpscompile/cps-c-calls.sml
4044 :    
4045 :     7. Added the conditional move operator
4046 :    
4047 :     condmove of branch
4048 :    
4049 : blume 2155 to cps. Generation of this is still buggy so it is currently

4057 :    
4058 : blume 2155 Implemented the Ball-Larus branch prediction-heuristics, and
4059 : george 1168 incorporated graphical viewers for control flow graphs.
4060 :    
4061 : george 1171 Ball-Larus Heuristics:
4062 : george 1168 ---------------------
4063 :     See the file compiler/CodeGen/cpscompile/cpsBranchProb.sml.
4064 :    
4065 :     By design it uses the Dempster-Shafer theory for combining
4066 :     probabilities. For example, in the function:
4067 :    
4068 :     fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)
4069 :    
4070 :     the ball-larus heuristics predicts that the n=0 is unlikely
4071 :     (OH-heuristic), and the 'then' branch is unlikely because of the
4072 :     RH-heuristic -- giving the 'then' branch an even lower combined
4073 : george 1171 probability using the Dempster-Shafer theory.
4074 : george 1168
4075 :     Finally, John Reppy's loop analysis in MLRISC, further lowers the
4076 :     probability of the 'then' branch because of the loop in the else
4077 :     branch.
4078 :    
4079 :    
4080 :     Graphical Viewing:
4081 : blume 2155 ------------------
4082 : george 1168 I merely plugged in Allen's graphical viewers into the compiler. The
4083 :     additional code is not much. At the top level, saying:
4084 :    
4085 :     Control.MLRISC.getFlag "cfg-graphical-view" := true;
4086 :    
4087 :     will display the graphical view of the control flow graph just before
4088 :     back-patching. daVinci must be in your path for this to work. If
4089 :     daVinci is not available, then the default viewer can be changed
4090 :     using:
4091 :    
4092 :     Control.MLRISC.getString "viewer"
4093 :    
4094 :     which can be set to "dot" or "vcg" for the corresponding viewers. Of
4095 :     course, these viewers must be in your path.
4096 :    
4097 :     The above will display the compilation unit at the level of clusters,
4098 :     many of which are small, boring, and un-interesting. Also setting:
4099 :    
4100 :     Control.MLRISC.getInt "cfg-graphical-view_size"
4101 :    
4102 :     will display clusters that are larger than the value set by the above.

4126 :     Description:
4127 :    
4128 : blume 2155 1. Recoded the buggy parts of x86-fp.
4129 : leunga 1156
4130 :     a. All the block reordering code has been removed.
4131 :     We now depend on the block placement phases to do this work.
4132 :    
4133 :     b. Critical edge splitting code has been simplified and moved into the
4134 :     CFG modules, as where they belong.
4135 :    
4136 :     Both of these were quite buggy and complex. The code is now much, much
4137 :     simpler.
4138 :    
4139 :     2. X86 backend.
4140 :    
4141 :     a. Added instructions for 64-bit support. Instruction selection for
4142 :     64-bit has not been committed, however, since that
4143 : blume 2155 requires changes to MLTREE which haven't been approved by
4144 : leunga 1156 Lal and John.
4145 :    
4146 : blume 2155 b. Added support for FUCOMI and FUCOMIP when generating code for
4147 : leunga 1156 PentiumPro and above. We only generate these instructions in
4148 :     the fast-fp mode.
4149 :    
4150 : blume 2155 c. Added cases for JP and JNP in X86FreqProps.
4151 :    
4152 : leunga 1156 3. CFG
4153 :    
4154 :     CFG now has a bunch of methods for edge splitting and merging.
4155 :    
4156 :     4. Machine description.
4157 :    
4158 :     John's simplification of MLTREE_BASIS.fcond broke a few machine
4159 :     description things:
4160 :    
4161 :     rtl-build.{sig,sml} and hppa.mdl fixed.
4162 :    
4163 : blume 2155 NOTE: the machine description stuff in the repository is still broken.
4164 :     Again, I can't put my fixes in because that involves
4165 :     changes to MLTREE.

4170 :     Tag: blume-20020320-kmp
4171 :     Description:
4172 :    
4173 :     Implemented Knuth-Morris-Pratt string matching in PreString and used
4174 :     it for String.isSubstring, Substring.isSubstring, and
4175 :     Substring.position.
4176 :    
4177 :     (Might need some stress-testing. Simple examples worked fine.)

4182 :     Tag: blume-20020319-witnesses
4183 :     Description:
4184 :    
4185 :     Added a structure C.W and functions convert/Ptr.convert to ml-nlffi-lib.
4186 :    
4187 :     This implements a generic mechanism for changing constness qualifiers
4188 :     anywhere within big C types without resorting to outright "casts".
4189 :     (So far, functions such as C.rw/C.ro or C.Ptr.rw/C.Ptr.ro only let you
4190 :     modify the constness at the outermost level.)
4191 :     The implementation of "convert" is based on the idea of "witness"
4192 :     values -- values that are not used by the operation but whose types
4193 :     "testify" to their applicability. On the implementation side, "convert"
4194 :     is simply a projection (returning its second curried argument). With
4195 :     cross-module inlining, it should not result in any machine code being
4196 :     generated.

4201 :     Tag: blume-20020315-basis
4202 :     Description:
4203 :    
4204 :     Provided (preliminary?) implementations for
4205 :    
4206 :     {String,Substring}.{concatWith,isSuffix,isSubstring}
4207 :    
4208 :     and
4209 :    
4210 :     Substring.full
4211 :    
4212 :     Those are in the Basis spec but they were missing in SML/NJ.

4218 :     Description:
4219 :    
4220 :     Controls:
4221 :     ---------
4222 :    
4223 :     1. Factored out the recently-added Controls : CONTROLS stuff and put
4224 :     it into its own library $/controls-lib.cm. The source tree for
4225 :     this is under src/smlnj-lib/Controls.
4226 :    
4227 :     2. Changed the names of types and functions in this interface, so they
4228 :     make a bit more "sense":
4229 :    
4230 :     module -> registry
4231 :     'a registry -> 'a group
4232 :    
4233 :     3. The interface now deals in ref cells only. The getter/setter interface
4234 :     is (mostly) gone.
4235 :    
4236 :     4. Added a function that lets one register an already-existing ref cell.
4237 :    
4238 :     5. Made the corresponding modifications to the rest of the code so that
4239 :     everything compiles again.
