217 :     Description:
218 :    
219 :     - Aaron: fixed a number of bugs in ml-ulex.
220 :     - Matthias:
221 :     - added CM control "cm.force-tools"; this is false by default;
222 :     when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
223 :     will be forced to run regardless of whether or not their targets
224 :     are up-to-date
225 :     - changed installer code so that config/install.sh will re-build
226 :     heap images for all tools even if those heap images already existed
227 :    
228 :     ----------------------------------------------------------------------
229 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
230 : blume 2688 Date: 2007/06/04 21:21:00 CDT
231 :     Description:
232 :    
233 :     After Aaron Turon's bug fix for ml-ulex (handling the ^ character
234 :     in legacy mode), re-ran the lexer generator on all lex input files
235 :     and committed the results.
236 :    
237 :     This should fix the problem with ckit and nlffi that was reported
238 :     by Vesa A. Norrman.

249 : dbm 2650 Name: Dave MacQueen (dbm@cs.uchicago.edu)
250 :     Date: 2007/05/31 14:55:00 CDT
251 :     Revision: 2650
252 :     Description:
253 :    
254 :     3rd merge of base from primop-branch-3 into the trunk.
255 :     Additional bug fixes included:
256 :    
257 :     * Timer.cpu_timer, etc. type printing corrected (by making
258 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
259 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
260 :     Stefan Monnier)
261 :    
262 :     ----------------------------------------------------------------------
263 : blume 2645 Name: Matthias Blume (http://www.tti-c.org/blume/)
264 :     Date: 2007/05/31 11:40:00 CDT
265 :     Description:
266 :    
267 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
268 :    
269 :     Also, changed the handling of "no core access": When translate.sml
270 :     needs access to a core exception at a time when the core has not
271 :     been set up yet (this only happens when compiling system/smlnj/init/*),
272 :     then don't bother generating the corresponding tests.
273 :    
274 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
275 :     the exception. Unfortunately, that confuses the plambda type checker.
276 :     Moreover, it does not do any good, because at runtime we don't expect
277 :     such an exception to be ever raised. (The code in system/smlnj/init/*
278 :     has to be written very carefully with this in mind!)

281 : mrainey 2639 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
282 :     Date: 2007/05/29
283 :     Description:
284 :    
285 :     Added FSQRT instructions for the AMD64 code generator.
286 :    
287 :     ----------------------------------------------------------------------
288 : blume 2626 Name: Matthias Blume (http://www.tti-c.org/blume/)
289 :     Date: 2007/05/29 19:00:00 CDT
290 :     Description:
291 :    
292 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
293 :     with an explicit test for zero division. This should fixes several
294 :     regressions and makes it possible for downstream optimization phases
295 :     to treat these operations as "pure" when they are applied to unsigned
296 :     operands.
297 :    
298 :     ----------------------------------------------------------------------
299 : mrainey 2622 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
300 :     Date: 2007/05/29
301 :     Description:
302 :    
303 :     Added the new MLRISC code generator for the AMD64. This version,
304 :     in contrast to the previous one, uses SSE registers and instructions
305 :     for all floating-point computations.
306 :

308 : jhr 2613 Name: John Reppy (http://www.cs.uchicago.edu/~jhr)
309 : jhr 2617 Date: 2007/05/29
310 : jhr 2613 Description:
311 :    
312 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
313 :     for bugs #1415 and #1416. We also now correctly handle format characters that
314 :     lie outside the specified set.

317 : blume 2610 Name: Matthias Blume (http://www.tti-c.org/blume/)
318 :     Date: 2007/05/23 22:30:00 CDT
319 :     Description:
320 :    
321 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
322 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
323 :    
324 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
325 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
326 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
327 :     while running CMB.make. The point is that the single symbol
328 :     NO_PLUGINS is definde in all three cases.)
329 :    
330 :     I changed the three locations within the sources that get compiled
331 :     during CMB.make where ml-yacc or ml-lex input is processed: When
332 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
333 :     is bypassed.
334 :    
335 :     When bootstrapping new versions of the compiler, there can be
336 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
337 :     are not available or otherwise not operational. In this case one can
338 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
339 :     do so, the following command should be issued at the interactive
340 :     prompt:
341 :    
342 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
343 :    
344 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
345 :     files that normally would be generated by ml-yacc and ml-lex.
346 :     (Copies of these files are in the repository.)

349 : dbm 2603 Name: David MacQueen (dbm@cs.uchicago.edu)
350 :     Date: 2007/5/23 17:23:00 CDT
351 :     Revision: 2603
352 :     Description:
353 :    
354 :     2nd merge of base from primop-branch-3 into the trunk.
355 :     Additional bug fixes included:
356 :     Date.scan and Date.fromString fixed;
357 :     Overloading resolution fixed and some type printing problems corrected.

360 : blume 2578 Name: Matthias Blume (http://www.tti-c.org/blume/)
361 : blume 2589 Date: 2007/05/23 09:50:00 CDT
362 :     Description:
363 :    
364 :     Changed the installation mechanism for CM tool plugins. These are
365 :     just libaries and now get installed like ordinary libaries.
366 :    
367 :     There are now a number of new installation targets that give some
368 :     fine-grain control over what classes and suffixes are known, and what
369 :     they will map to.
370 :     See config/targets for details.
371 :    
372 :     The code that caused plugin installation as part of running a
373 :     tool's "build" script has been removed. (The build script is for
374 :     building, not for installing.)
375 :    
376 :     ----------------------------------------------------------------------
377 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
378 : blume 2578 Date: 2007/05/22 11:50:00 CDT
379 :     Description:
380 :    
381 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
382 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
383 :     CM fail if a shell tool reports a non-success exit status. If
384 :     the control is set to true, then CM will press on after tool failures
385 :     in the event that the target files exist (even though they are
386 :     considered outdated). Turning the control to true can be useful for
387 :     bootstrapping.

390 : adrassi 2570 Name: Aaron Turon (http://www.cs.uchicago.edu/~adrassi)
391 :     Date: 2007/05/19
392 :     Description:
393 :    
394 :     Merge of ml-lpt revisions for 110.64.
395 :    
396 :     The name of several ml-lpt-lib modules has changed:
397 :     Repair => AntlrRepair
398 :     StreamPos => AntlrStreamPos
399 :     ErrHandlerFn => AntlrErrHandler
400 :     EBNF => AntlrEBNF
401 :    
402 :     The ml-antlr specification format has changed: declarations such as
403 :     %tokens and nonterminal definitions can occur *multiple* times in the
404 :     same specification. The semantics are such that each new declaration
405 :     extends the previous ones. This does not apply to %start or %name,
406 :     of course.
407 :    
408 :     Importing a grammar via %import now includes *all* declarations in from
409 :     the imported grammar, except for %name, %entry, and %start. Tokens
410 :     and nonterminals can be dropped using the new %dropping clause of the
411 :     %import directive; the separate %drop and %extend have been removed.
412 :    
413 :     We now allow optional type annotations on nonterminals, using the %nonterms
414 :     directive as in ml-yacc.
415 :    
416 :     The refcell construct is now implemented using SML's regular reference
417 :     cells, so the :== and !! notation has been deprecated.
418 :    
419 :     The ml-antlr tool now does much more checking of specifications, and
420 :     its error messages have been greatly improved. Error repair for
421 :     generated parsers has been completely rewritten, and is now both
422 :     much faster and more accurate.
423 :    
424 :     ml-ulex is now more lenient with escape codes (non-SML-standard
425 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
426 :     Also, character classes may now include a "-" character at the beginning
427 :     as is standard in most other regexp tools.
428 :    
429 :     All of these changes are documented in the user guide, which has
430 :     been updated and improved with this merge.

435 :     Revision: r2492
436 :     Description:
437 :    
438 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
439 :     Significant changes in FLINT and the front end, mostly having to do
440 :     with a reorganized system for handling primops. Various bug fixes
441 :     and improvements in printing signatures.

446 :     Description:
447 :    
448 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
449 :     The ml-antlr specification format has changed: declarations such as
450 :     %tokens and nonterminal definitions can occur *multiple* times in the
451 :     same specification. The semantics are such that each new declaration
452 :     extends the previous ones. Grammar extension constructs have also
453 :     changed. We now allow type annotations on nonterminals. Finally,
454 :     the refcell construct is now implemented using SML's regular reference
455 :     cells, so the :== and !! notation has been deprecated. All of these
456 :     changes will appear in the 110.64 user guide for ml-lpt.
457 :    
458 :     The ml-antlr tool now does much more checking of specifications, and
459 :     its error messages have been greatly improved. There has also been
460 :     some work on the error repair process for generated parsers, but this
461 :     will be further improved in 110.64.

498 :    
499 :     More Basis fixes: The Char.fromString (etc.) functions did not handle
500 :     the "\uxxxx" escape sequence. There is still an outstanding bug with
501 :     String.fromString the tail is a format escape. I added a comment to

580 :     Date: 2007/02/26
581 :     Description:
582 :    
583 :     Added preliminary support in MLRISC for Staged Allocation, a technique
584 :     for specifying calling conventions (see
585 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
586 :     Initially, we plan to use this code to generate C calls for the AMD64.
587 :    
588 :     The staged allocation code base resides in MLRISC/staged-allocation,
589 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

595 :    
596 :     Bug fix: when SaveCState was called with two values to save, a subsequent
597 :     GC could cause the RestoreCState to fail because the saved state had been
598 :     promoted to tagless pair.

608 :     val _ = Word8Array.update(a1, 0, 0w128);
609 :    
610 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
611 :     of the range -128 ... 127. I've changed the code so that the range
612 :     check is disabled. Only the low order 8 bits of the immediate operand
613 : jhr 2342 are now significant.

621 :     Eliminated any mention of lexgen. (Lexgen was an early precursor
622 :     to ml-ulex.)

653 :     Date: 2007/01/31
654 :     Description:
655 :    
656 :     Brought ml-lpt manual up-to-date with the code. Many minor
657 :     improvements to the tools, and a few minor bugfixes. Prepared
658 :     ml-lpt-lib for integration with new UTF8 structure. Changed
659 :     the interface for creating streams in ml-ulex (we now support
660 :     stream creation from several kinds of sources). Overall, the
661 :     tools are now quite stable, and their interfaces are unlikely to
662 :     change in a way that would break compatibility. More work,
663 :     however, is needed in the documentation.

667 : blume 2298 Date: 2007/02/01 10:05:00 CST
668 :     Description:
669 :    
670 :     Implemented library installer. Moved CM plugin code for
671 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
672 :     their respective trees. Implemented CM plugin for ml-ulex
673 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
674 :     and ml-antlr.
675 :    
676 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
677 :     CM tools. (It turns out to be too messy to do otherwise because
678 :     there is too much code that during installation relies on the presence
679 :     of these tools -- resulting in a tricky ordering problem.)

683 : blume 2277 Date: 2007/01/30 11:05:00 CST
684 :     Description:
685 :    
686 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
687 :     Modified CM's startup code to use shiftArgs as it processes
688 :     command line arguments. This way, the init code in each .sml-file
689 :     or library that is mentioned at the top level will see only
690 :     those arguments that have not yet been processed at this point.
691 :     In other words, the init code can "seize control" and process the
692 :     remaining command line.

706 :    
707 :     Added the UTF8 structure and signature from the Moby compiler to
708 :     the SML/NJ library (and the CML library). These modules will replace
709 :     the version in the ml-lpt-lib.

749 :    
750 :     Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to
751 :     get the c_cc termios data copied correctly. Also moved the allocation
752 :     of the string to avoid problems if it caused a GC.

758 :     Date: 2006/12/08 09:50:00 CST
759 :     Description:
760 :    
761 :     Added code to CM's "standard shell tool" implementation which
762 :     causes it to tolerate (with a warning) the situation where the shell
763 :     command fails (e.g., due to the shell command's non-existence)
764 :     as long as all target files exist.
765 :    
766 :     This makes it possible to, e.g., build ml-yacc from sources even if
767 :     svn checkout messed up the time stamps on files in such a way that
768 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
769 :     be needed to re-process yacc.grm, but obviously it might not yet be
770 :     available at that time.)

776 :    
777 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
778 :     recvVecFromNB' in the SOCKET signature. This error is actually
779 :     in the SML Basis specification too.

784 :     Description:
785 :

787 :     rather than silently pressing on using bogus values.

793 :    
794 :     Use Say.vsay for printing the "[autoloading]" message, so

811 :    
812 :     New working release (110.60). NEW BOOTFILES!
813 :    
814 :     This is the first subversion-hosted release. There are also changes
815 :     to the directory layout. Here is a table:
816 :    
817 :     (All pathnames are relative to the SML/NJ "root" directory.)
818 :    
819 :     config -> config
820 :

834 :     src/MLRISC -> MLRISC
835 :     ckit -> ckit
836 :     src/cml -> cml
837 :     src/eXene -> eXene
838 :     src/heap2asm -> heap2asm
839 :     src/lexgen -> lexgen
840 :     src/ml-burg -> ml-burg
841 :     src/ml-lex -> ml-lex
842 :     src/ml-yacc -> ml-yacc

845 :     src/smlnj-c -> smlnj-c
846 :     src/tools/TraceDebugProf -> trace-debug-profile
847 :    
848 :     In addition, there is also a new
849 :    
850 :     ml-lpt
851 :    
852 :     directory containing two new program generator tools: ml-ulex and
853 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
854 :     LL(k) parser generator). These tools are currently "beta-quality"
855 :    
856 :     The latest versios of the sources can now be obtained anonymously
857 :     via subversion. For this, it is useful to first check out
858 :    
859 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
860 :    
861 :     and put the resulting directory on your shell's PATH. This provides
862 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
863 :     and refresh-all.sh.
864 :    
865 :     To create a freshly checked-out copy of the sources, do
866 :    
867 :     checkout-all.sh [dir]
868 :    
869 :     where dir is the optional SML/NJ root directory (default is ".").
870 :    
871 :     This creates the above directory layout. Each subdirectory of
872 :     the root is under individual subversion control. The stat-all.sh
873 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
874 :     each of these subtrees.

879 :     Description:
880 :    
881 :     Reorganized directory layout.
882 :    
883 :     This is a temporary solution, more reorganization is to come.
884 :    
885 :     The basic idea is to have a number of toplevel trees, each corresponding
886 :     to a well-defined part of the overall system. Each part can be
887 :     maintained individually, even in separate source repositories,
888 :     although currently we still serve everything out of the main
889 :     smlnj-gforge tree.
890 :    
891 :     Installer and and scripts have been updated to reflect the new
892 :     layout. The installer (base/src/system/smlnj/installer) is now
893 :     "scriptable" to avoid burning too much knowledge about the
894 :     layout into SML source code. The main script used by the installer
895 :     is in config/actions.
896 :    
897 :     The main change is that many of the subdirectories of what used to
898 :     be known as "src" have moved to the toplevel. The "src" directory
899 :     itself has moved down into a subtree called "base". (We may eventually
900 :     get rid of the extra level of indirection represented by "src".)
901 :    
902 :     The layout is now as follows:
903 :    
904 :     toplevel tree name | default repository
905 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
906 :     -------------------+----------------------------------------------------
907 :     config | $gf/config/trunk
908 :     |
909 :     base | $gf/sml/trunk
910 :     |
911 :     smlnj-lib | $gf/smlnj-lib/trunk
912 :     MLRISC | $gf/MLRISC/trunk
913 :     |
914 :     ml-yacc | $gf/ml-yacc/trunk
915 :     ml-lex | $gf/ml-lex/trunk
916 :     ml-burg | $gf/ml-burg/trunk
917 :     lexgen | $gf/lexgen/trunk
918 :     heap2asm | $gf/heap2asm/trunk
919 :     |
920 :     cml | $gf/cml/trunk
921 :     eXene | $gf/eXene/trunk
922 :     ckit | $gf/ckit/trunk
923 :     nlffi | $gf/nlffi/trunk
924 :     |
925 :     smlnj-c | $gf/smlnj-c/trunk
926 :    
927 :     In $gf/admin there are a few useful shell scripts for checking out
928 :     and maintaining the entire collection of trees:
929 :    
930 :     admin/checkout-all.sh [dir]
931 :     -- optionally creates dir and checks out all trees from their
932 :     default repositories; if dir is missing, checkout into .
933 :     admin/refresh-all.sh [dir]
934 :     -- looks at all trees (from the above list) in dir (default: .)
935 :     and runs "svn update" if the tree exists and is under
936 :     subversion control;
937 :     non-existing or non-subversion trees are skipped
938 :     admin/stat-all.sh [dir]
939 :     -- like refresh-all.sh, but runs "svn stat" instead

1120 :    
1121 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1122 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1123 : blume 2155 at the time when config/preloads is processed, the library has to
1124 : mblume 1878 be referred to by another name. In 110.57 this would be
1125 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1126 :     to be valid as well.)

1182 :     Description:
1183 :    
1184 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1185 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1186 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1187 :     it. Instead, it has the status of "user code", so it should use
1188 :     $/basis.cm to refer to the Basis library. (At least that's true for
1189 :     the purpose of bootstrapping the previous change. In the future it
1190 :     might make sense to have versiontool.cm refer to
1191 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1192 :     compiler itself uses.)

1195 :     bindings in config/extrapathconfig.

1200 :     Tag: blume-22051115-libraries
1201 :     Description:
1202 :    
1203 :     This change affects the way the following libraries are tied into
1204 :     the system:
1205 :    
1206 :     $/basis.cm
1207 :     $/smlnj-lib.cm
1208 :     $/pp-lib.cm
1209 :     $/controls-lib.cm
1210 :     $/html-lib.cm
1211 :     $/ml-yacc-lib.cm
1212 :    
1213 :     These libraries are now internally (as seen from the source code
1214 :     of the implementation itself) known by the following names:
1215 :    
1216 :     $smlnj/basis/basis.cm
1217 :     $smlnj/smlnj-lib/smlnj-lib.cm
1218 :     $smlnj/smlnj-lib/pp-lib.cm
1219 :     $smlnj/smlnj-lib/controls-lib.cm
1220 :     $smlnj/smlnj-lib/html-lib.cm
1221 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1222 :    
1223 :     This makes it possible to work with code that requires different
1224 :     versions of these libraries, and which refers to these libraries using
1225 :     their "default" names (i.e., the first set of names above). In other
1226 :     words, one can un-define or re-define those default names without
1227 :     compromising the proper functioning of the compiler itself.
1228 :    
1229 :     A similar procedure had already been performed for several of the
1230 :     MLRISC libraries that are linked into the compiler. I did some
1231 :     cleanup on this code.
1232 :    
1233 :     A new file in the config directory (named extrapathconfig) is
1234 :     responsible for setting up path anchors that the compiler itself does
1235 :     not need, but that are typically required by user code.

1414 :     Tag: blume-20050516-redump-heap
1415 :     Description:
1416 :    
1417 :     Added mechanism for re-creating a heap file for the interactive system
1418 :     after configuration variables have been changed.
1419 :    
1420 :     CM.redump_heap : string -> unit
1421 :    
1422 :     This is much like SMLofNJ.exportML, but starting from the resulting
1423 : blume 2155 heap does not return to the caller of CM.redump_heap but
1424 : mblume 1792 restarts the interactive system from scratch. The original call of
1425 :     CM.redump_heap does not return but ends the interactive session.
1426 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1427 :    
1428 :     Internally, redump_heap winds the dynamic execution context back to
1429 :     the point where the original heap image was created and re-executes
1430 :     the heap image generation code in the boot code.

1546 :     Tag: blume-20050114-heap2exec
1547 :     Description:
1548 :    
1549 :     Implemented new (but still experimental) heap2exec facility. This is
1550 :     tested under Mac OS X and should work under Linux (will test shortly).
1551 :     It will probably also work on the Sparc (will test some time later).
1552 :    
1553 :     - removed old "HACKED_STANDALONE" hack from runtime
1554 :    
1555 :     To be able to test this, uncomment the request for "heap2asm" in
1556 :     config/targets prior to installation. (Notice that this is different
1557 :     from "heap2exec" mentioned below. Not a typo.)
1558 :    
1559 :     To perform an actual test, run the command
1560 :    
1561 :     $ bin/heap2exec heapfile execfile
1562 :    
1563 :     (You can put heap2exec on your shell's path.)
1564 :    
1565 :     For example, run
1566 :    
1567 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1568 :    
1569 :     This will create a standalone executable called "mly" which you can
1570 :     then invoke directly as a command.

1597 :    
1598 :     * Fixed CM's incorrect assumption that the PPC is little-endian.

1715 :     Tag: blume-20041124-position
1716 :     Description:
1717 :    
1718 :     The compiler can now be compiled in a mode that makes structure Position
1719 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1720 :     for the time being.
1721 :    
1722 :     To enable 64-bit positions, use the following procedure:
1723 :    
1724 :     1. Start sml
1725 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1726 :     3. Type
1727 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1728 :     4. Run CMB.make() as usual.
1729 :    
1730 :     This is barely tested. The only test so far was a little SML program
1731 :     counting the number of characters in an 8-gigabyte file by
1732 :     reading it character-by-character. That test was successful.
1733 :    
1734 :     In support of 64-bit positions, a number of new functions have been
1735 :     added to the runtime system.

1779 :     The date string is generated at bootstrap time (during makeml).
1780 :    
1781 :     - In a previous commit, fixed a minor issue with how polyequal is being
1782 :     translated. In particular, the code now "looks through" abstractions.
1783 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1784 :     more efficient code. Important examples for where this matters are
1785 :     the new int64 and word64 types.

1800 :     Description:
1801 :    
1802 :     All the pieces of Word64 are now there, with the exception of the
1803 :     conversions from and to LargeWord. (Eventually these need to be identities,
1804 :     but for the time being they don't even make sense because LargeWord is
1805 :     32-bit wide.)
1806 :    
1807 :     Also started to add similar support for Int64, but major pieces of that
1808 :     are still missing.

1813 :     Tag: blume-20041111-word64
1814 :     Description:
1815 :    
1816 :     Structure Word64 is now (almost) complete, word literals and patterns
1817 :     seem to work. There are a few odd pieces missing. In particular,
1818 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1819 :     at the moment.
1820 :    
1821 :     Making Word64 official would mean that LargeWord becomes Word64. But
1822 :     this requires extreme care because most word-word conversions have to
1823 :     go through LargeWord, so making a mistake means loss of efficiency or
1824 :     worse. Eventually there will be a solution similar to (but actually
1825 :     simpler than) what I did with IntInf.

1860 :     - Made corresponding changes to config/install.sh and config/unpack.
1861 :     - Default contents of config/srcarchiveurl uses $VERSION and
1862 :     normally does not have to be edited to reflect a version change.
1863 :    
1864 :     (As a result, a version change can be done by just editing
1865 :     config/version, the rest is now automatic.)

1905 :     Tag: blume-20041020-standalone-backtrace
1906 :     Description:
1907 :    
1908 :     Added a mechanism for getting back-trace information from standalone
1909 :     programs. Here is how it works:
1910 :    
1911 :     1. The part of the program from which you want to get backtrace
1912 :     information (usually the whole program) should be wrapped with
1913 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
1914 :     main program could be modified from something like
1915 :    
1916 :     fun main (pgm, args) = ...
1917 :    
1918 :     to
1919 :    
1920 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1921 :    
1922 :     2. To be able to access BackTrace.monitor, you have to add
1923 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
1924 :     main function.
1925 :    
1926 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1927 :     CM might have created in the past for your project).
1928 :    
1929 :     4. Build the system using this command line:
1930 :    
1931 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1932 :     myprog.cm MyProg.main myprog
1933 :    
1934 :     instead of the usual
1935 :    
1936 :     ml-build myprog.cm MyProg.main myprog
1937 :    
1938 :     I changed a library name:
1939 :    
1940 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1941 :    
1942 :     New libraries:
1943 :    
1944 :     $smlnj-tdp/back-trace.cm
1945 :     -- when loaded causes the back-trace plugin to be installed
1946 :     $smlnj-tdp/coverage.cm
1947 :     -- when loaded causes the coverage plugin to be installed

1963 :     Description:
1964 :    
1965 :     * Test coverage tool added!
1966 :     * Further reorganization of tracing-, debugging-, and profiling support:
1967 :    
1968 :     - moved original BTImp -- now called BackTrace -- into a separate
1969 :     library called $/trace-debug-profile.cm
1970 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
1971 :     - only the instrumentation mechanism is now left in the compiler proper
1972 :     - BackTrace module is a plugin which is NOT plugged in by default
1973 :     - Coverage module is another such plugin
1974 :    
1975 :     To get the benefits of any of these plugin modules, the code in
1976 :     question must be compiled with tdp instrumentation turned on. This
1977 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
1978 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1979 :    
1980 :     Plugins are selected at link time. (Pre-compiled instrumented code
1981 :     can be re-loaded with different plugins in effect.) When an
1982 :     instrumented module is linked, whatever plugins are at that time
1983 :     enabled will come into effect for that module.
1984 :    
1985 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
1986 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
1987 :     To enable the coverage plugin, load the same library and invoke
1988 :     Coverage.install().
1989 :    
1990 :     Back-traces are generated automatically on uncaught exceptions and
1991 :     when the code in question explicitly invokes BackTrace.trigger().
1992 :    
1993 :     Coverage (and execution frequency-) information must be queried
1994 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2085 :     Added hack to make slave mode work in the presence of the version
2086 :     tool. (Still, since the master does two passes over the code for
2087 :     CMB.make, the release number gets bumped twice when slaves are
2088 :     attached. I don't know if this is worth fixing...)

2094 :     Description:
2095 :    
2096 :     * Moved the "version" magic into its own little library under
2097 : mblume 1672 src/system/smlnj/internal. This avoids expensive reconstruction of
2098 :     a stable src/compiler/core.cm.
2099 : mblume 1639
2100 : mblume 1672 * At the same time, structure CompilerVersion is now known as
2101 :     structure SMLNJVersion.
2102 : mblume 1639
2103 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2104 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2105 :     Also, loading the versiontool does not work when rebuilding the system
2106 :     because CM is not properly initialized at that time.

2111 :     Tag: blume-20040929-autoversion
2112 :     Description:
2113 :    
2114 :     Implemented some CM magic to have
2115 :     file src/compiler/TopLevel/main/version.sml
2116 :     generated automagically.
2117 :     The version is taken from two files: config/version and config/release.
2118 :     The first is expected to contain a two-part version number such as 110.49.
2119 :     The second should contain a single number, but it may be missing.
2120 :    
2121 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2122 :     time the version tool is loaded (which is the first time you say CMB.make),
2123 :     then the tool will increment the value stored in config/release every
2124 :     time CMB.make is invoked.
2125 :    
2126 :     The binfile format is now insensitive to anything beyond the first
2127 :     two components of a version number, so bumping the release does not render
2128 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2129 :     during development without invalidating existing binfiles.
2130 :    
2131 :     In any case, every CMB.make updates the date information in version.sml.
2132 :     (This is the date that is printed in the banner.)

2145 :     Tag: blume-20040927-controls
2146 :     Description:
2147 :    
2148 :     Added two pieces of functionality to the Controls interface:
2149 :    
2150 :     1. val save'restore: 'a control -> unit -> unit
2151 :    
2152 :     grabs the current value of the control in stage 1 and restores it
2153 :     in stage 2.
2154 :    
2155 :     2. val set' : 'a control * 'a -> unit -> unit
2156 :    
2157 :     stores the given value into the control in stage 2 (i.e., delayed)
2158 :     but does all error checking in stage 1.
2159 :     (This is for string controls that need to do parse their argument --
2160 :     something that might fail. In some cases, notably in CM, one
2161 :     already knows the intended argument but wants to delay the actual
2162 :     assignment until a time when error recovery would be more difficult.)
2163 :    
2164 :     Changed the handling of controls in tool arguments to classes "sml" and
2165 :     "lazysml":
2166 :     - use Controls.save'restore as a more robust way of restoring the
2167 :     old value (in particular: without having to re-parse the string)
2168 :     - use controls to handle the "overload" keyword in the init group
2169 :     (I believe this change actually fixes a long-standing obscure bug.)

2174 :     Tag: blume-20040927-lazysml
2175 :     Description:
2176 :    
2177 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2178 :     difference to "sml" is that compilation is done with Control.lazysml
2179 :     set to true. A source of class "lazysml" is automatically recognized
2180 :     by a file name suffix of ".lml".
2181 :    
2182 :     In addition to the above feature, the original class "sml" now also
2183 :     supports a tool argument "lazy" which has the same effect. As a
2184 :     result, the following three lines are equivalent:
2185 :    
2186 :     foo.sml : lazysml
2187 :     foo.sml : sml (lazy)
2188 :     foo.sml (lazy)
2189 :    
2190 :     The setting goes into effect both during parsing and during
2191 :     compilation. The original setting is restored right after parsing and
2192 :     after compilation, respectively.
2193 :    
2194 :     In addition to all the above, there is also a general mechanism to set
2195 :     ANY of the "controls" that are available at the command line via
2196 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2197 :     apply as well. (In fact, "lazy" is implemented as a special case of
2198 :     the general mechanism.)
2199 :    
2200 :     The .cm file syntax uses a new keyword tool argument called "with".
2201 :     There are several ways of indicating the desired settings:
2202 :    
2203 :     foo.sml (with:parser.quotations=true)
2204 :     foo.sml (with:(name:parser.quotations value:true))
2205 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2206 :     foo.sml (with:(name1=value1 name2=value2 ...))
2207 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2208 :    
2209 :     etc.
2210 :    
2211 :     Another possible abbreviation is to leave out the =v or value:v part
2212 :     if the name refers to a boolean control (in which case the value is
2213 :     taken to be true). Thus, one could get lazy sml also by saying:
2214 :    
2215 :     foo.sml (with:parser.lazy-keyword=true)
2216 :     foo.sml (with:parser.lazy-keyword)
2217 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2218 :     foo.sml (with:(name:parser.lazy-keyword))

2478 :     Added C_UNION to c-calls/c-types.sml and updated the machinery
2479 :     (ml-nlffigen, cproto.sml) that conveys C function interface
2480 :     information to the code generator.
2481 :    
2482 :     However, the actual architecture-specific implementation of function
2483 :     arguments and results that are C unions is still not implemented.

2570 :     Description:
2571 :    
2572 :     Changed the interface of structures Timer and Unix to match the most
2573 :     recent Basis spec.
2574 :    
2575 :     In the case of Unix there still seems to be an open/weird issue:
2576 :    
2577 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2578 :     fresh streams whenever they are called -- as opposed to have them
2579 :     return the same stream every time. This design is supposed to
2580 :     prevent space leaks caused by proc values hanging on to streams.
2581 :    
2582 :     The reap function, on the other hand, is supposed to close the
2583 :     streams. This cannot be done without having a handle on the
2584 :     stream in proc after all...
2585 :    
2586 :     I took the liberty to implement the following stopgap solution:
2587 :    
2588 :     The proc value hangs on to the most recently created stream(s).
2589 :     Reap closes those. If either or both of the two streams hadn't
2590 :     been created at all yet, then reap will close the corresponding
2591 :     file descriptors directly.
2592 :    
2593 :     PS: I don't understand the original space leak argument anymore. If
2594 :     a proc hangs on to the imperative stream, then I/O operations on those
2595 :     will advance the state of the cached stream and avoid the space leak.

2608 :     Tag: blume-20040525-group-owner
2609 :     Description:
2610 :    
2611 :     CM now ignores (but still accepts) the "owner" information in group
2612 :     descriptions. The owner of a group is its next enclosing
2613 :     library. Each group must have a unique owner. (There is a virtual
2614 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2615 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2616 :     and CM would check that such a declaration is correct. The new scheme
2617 :     is to have CM check that for each group there is precisely one owning
2618 :     library.
2619 :    
2620 :     The advantage of the new scheme is that the programmer no longer needs
2621 :     to maintain the somewhat annoying owner information. The downside is
2622 :     that CM cannot enforce the ownership rule across multiple runs of
2623 :     CM.make. Fortunately, enclosing the same group in two different
2624 :     libraries A and B which are not part of the same program does not
2625 :     cause real problems.

2644 :     Description:
2645 :    
2646 :     Arranged for ml-build to clean up after itself a little bit better.
2647 :     The script generates a temporary SML source file and compiles it using
2648 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
2649 :     gets rid of those at the end, so they don't accumulate under .cm.
2650 :    
2651 :     This required a minor change to install.sh because the name of the
2652 :     metadata directory (default: .cm) is actually configurable at
2653 :     installation time.

2671 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
2672 :     for the voluminous patch!
2673 :    
2674 :     (I have not tested this patch under win32 yet.)
2675 :    
2676 : mblume 1490 Here is David's e-mail:
2677 :    
2678 :     Hi,
2679 :    
2680 :     Attached to this email you find a diff against sml/nj 110.45
2681 :     that will enable socket support under Windows.
2682 :    
2683 :     To apply the patch (using unix or cygwin)
2684 :     1) gunzip runtime.diff.gz
2685 :     2) "cd" into "src/runtime" in the source tree of a fresh
2686 :     110.45 installation.
2687 :     3) patch -p 1 < [your/path/to]runtime.diff
2688 :    
2689 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2690 :     I only ran a few tests for basic socket client functionality
2691 :     (which worked fine). Especially the functions that use ioctl
2692 : mblume 1490 are not tested at all and might not work (see below).
2693 :    
2694 :     I implemented this since we want to move to a newer version of sml/nj
2695 :     but need socket support in order to use it. This is the first time I
2696 :     even had a look at the sml/nj source, so please review my changes
2697 :     before making this part of the distribution! Here are a few issues
2698 : blume 2155 that I think might be better for someone to solve who is more
2699 : mblume 1490 familiar with the sml/nj source (and socket programming):
2700 :    
2701 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2702 :     exception since I could not figure out what the windows equivalent
2703 :     of these functions is
2704 :    
2705 :     - In sockets-osdep.h there are a some #include statements that are
2706 :     only used in a few files that include sockets-osdep.h
2707 :    
2708 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2709 :     does not process its return value since I don't know how to
2710 :     report an error upwards.
2711 :    
2712 :     - It would probably be good to have a call to WSACleanup() when
2713 : blume 2155 the library is unloaded (if there is such a possibility).
2714 : mblume 1490 Otherwise I think Windows will take care of this automatically
2715 :     when the process finishes.
2716 :    
2717 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2718 :     no idea if that is actually the proper replacement on Windows.
2719 :    
2720 :     - All these issues are marked in the code by "FIXME" comments.
2721 :    
2722 : blume 2155 We use sml/nj extensively in our products and are quite happy
2723 :     with it. I hope this contribution will help you.
2724 : mblume 1490
2725 :     Keep up the good work!

2890 :     Description:
2891 :    
2892 :     Eliminated the "dont_move_libraries" directive in config/targets.
2893 :     (The mechanism was broken and could not be fixed easily. Moreover,
2894 :     there does not seem to be any reason not to move all libraries into
2895 :     lib during installation. I originally implemented this directive as a
2896 :     backward-compatibility feature when I first introduced the new CM.
2897 :     Now that things have been stable for a long time and going back to the
2898 :     old CM is not an option, there is no reason to keep it around.)

2947 :     Tag: blume-20030926-ppautoload
2948 :     Description:
2949 :    
2950 :     I modified the read-eval-print loop so that the autoloader gets
2951 :     invoked whenever the prettyprinter tries to look up a symbol that
2952 :     is not currently defined in the toplevel environment but which
2953 :     appears in CM's autoload registry. As a result, we see far fewer of
2954 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
2955 :    
2956 :     In addition to this I tried to clean up some pieces of the Basis
2957 :     implementation (e.g., Socket, Word8Array) in order to prevent other
2958 :     instances of these ?.Foo.Bar.xxx names from being printed.
2959 :    
2960 :     The mechanism that picks names for types still needs some work, though.
2961 :     (Right now it seems that if there is a type A.t which is defined to
2962 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
2963 :     "?.B.u" although the perhaps more sensible solution would be to use
2964 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
2965 :     a chain of DEFtycs not farther than there are corresponding toplevel
2966 :     names in the current environment.)

2972 :     Description:
2973 :    
2974 :     Another installer tweak: All the ML code for the installer is now
2975 :     compiled during CMB.make and put into a little library called
2976 :     $smlnj/installer.cm. The installation then simply invokes
2977 :    
2978 :     sml -m $smlnj/installer.cm
2979 :    
2980 :     and everything happens automagically.
2981 :    
2982 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
2983 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
2984 :     and BINDIR.
2985 :    
2986 :     The new scheme guarantees that the ML code responsible for the installation
2987 :     is in sync with the APIs of the main system. Also, the installer is
2988 :     somewhat faster because the installer script is precompiled.

2995 :    
2996 :     Added a signature SYNCHRONOUS_SOCKET to basis.cm. This is like SOCKET
2997 :     but excludes all non-blocking operations. Defined SOCKET (in Basis)
2998 :     and CML_SOCKET in terms of SYNCHRONOUS_SOCKET. Removed superfluous
2999 :     implementations of non-blocking operations from CML's Socket
3000 :     structure.

3005 :     Tag: blume-20030924-sockets
3006 :     Description:
3007 :    
3008 :     1. Fixed SOCKET API and implementation to match Basis spec.
3009 :     This required changing the internal representation of sockets to one
3010 :     that remembers (for each socket file descriptor) whether it is currently
3011 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3012 :     call is made only if the state actually needs to change).
3013 :    
3014 :     2. OS-specific details of sockets were moved into separate files, thus
3015 :     making it possible to unify the bulk of the socket implementations
3016 :     between Unix and Win32.
3017 :    
3018 :     3. CML's socket API changed accordingly.
3019 :     (Note that we need to remove non-blocking functions from this API
3020 :     since they are redundant in the case of CML!)
3021 :    
3022 :     4. CML's socket implementation now makes use of non-blocking functions
3023 :     provided by Basis, thus removing all OS-dependent code from this part
3024 :     of CML.
3025 :    
3026 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3139 :     Description:
3140 :    
3141 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3142 :     Modified config/install.bat to take advantage of it. Also modified
3143 :     config/install.sh (and called it config/new-install.sh) to take advantage
3144 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3145 :     independent.)
3146 :    
3147 :     The installer can now install everything under Win32
3148 :     as well as under *nix as long as it compiles.
3149 :    
3150 :     Other changes:
3151 :    
3152 :     - made CML compile again under Win32
3153 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3154 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3155 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3156 :     same as type int; under Win32 it isn't
3157 :     - fixed some slice-related problems in the win32-specific parts of CML
3158 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3159 :     (under Win32, the volume name is case-insensitive, and the
3160 :     OS.Path code compares volume names for equality)

3177 : mblume 1350 Description:
3178 :    
3179 :     1. Changed interface to vectors and arrays in Basis to match
3180 :     (draft) Basis spec.
3181 :     2. Added signatures and implementations of slices according to
3182 :     Basis spec.
3183 :     3. Edited source code throughout the system to make it compile again
3184 :     under 1. and 2. (In some cases code had to be added to have it
3185 :     match the new signatures.)
3186 :     4. MLRISC should be backward-compatible: the copies of the originals
3187 :     of files that needed to change under 3. were retained, the .cm files
3188 :     check the compiler version number and use old versions when
3189 :     appropriate.
3190 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3191 :     dirstream -> string option (in accordance with Basis spec).
3192 :     6. When generating code that counts lines, ml-lex used function
3193 :     CharVector.foldli, taking advantage of its old interface.
3194 :     This has been replaced with the corresponding code from
3195 :     CharVectorSlice. (html-lex must be re-lexed!)
3196 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3197 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3198 :     8. Removed temporary additions (fromInternal, toInternal) from the
3199 :     (now obsolete) IntInf in smlnj-lib/Util.
3200 :     9. Cleaned up structure Byte.
3201 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3202 :     Cleaned/corrected implementation of Date.
3203 :     (Still need to check for correctness; implement better canonicalizeDate.)
3204 :     11. Added "scan" to signature IEEE_REAL.
3205 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3206 :     mod and rem when second operand is 2 (for parity checks).]
3207 :     13. Changed representation of type Time.time, using a single IntInf.int
3208 :     value counting microseconds. This considerably simplified the
3209 :     implementation of structure Time. We now support negative time
3210 :     values; scan and fromString handle signs.
3211 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3212 :     ArraySlice).

3218 :     Description:
3219 :    
3220 :     This is a major update which comes with a version number bump
3221 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3222 :     and an implementation of IntInf in the Basis.
3223 :    
3224 :     There are a fairly large number of related changes and updates throughout
3225 :     the system:
3226 :    
3227 :     Basis:
3228 :     - Implemented IntInf.
3229 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3230 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3231 : mblume 1347 - Added FixedInt as a synonym for Int32.
3232 :    
3233 :     compiler:
3234 :     * Added support for a built-in intinf type.
3235 :     - literals
3236 :     - pattern matching
3237 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3238 :     - overloading on literals and operations
3239 :    
3240 :     This required adding a primitive type intinf, some additional
3241 :     primops, and implementations for several non-trivial intinf
3242 :     operations in Core. (The intinf type is completely abstract
3243 :     to the compiler; all operations get delegated back to the Core.)
3244 :    
3245 :     * Intinf equality is handled by polyequal. However, the compiler
3246 :     does not print its usual warning in this case (since polyequal
3247 :     is the right thing to do there).
3248 :    
3249 :     * Improved the organization of structure InlineT.
3250 :    
3251 :     * A word about conversion primops:
3252 :     If conversions involving intinf do not cancel out during
3253 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3254 : mblume 1347 Since all core access must be resolved already during the FLINT
3255 :     translate phase, it would be too late a the time of CPS contract
3256 : mblume 1348 to add new Core calls. For this reason, conversion primops
3257 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3258 :     they are supposed to convert, and 2. the Core function that

3260 : mblume 1348 eliminates a primop, then the associated Core function becomes
3261 :     dead and goes away. Intinf conversion primops that do not get
3262 :     eliminated by CPS contract get rewritten into calls of their
3263 :     core functions by a separate, new phase.

3304 :     Tag: blume-20030811-windows
3305 :     Description:
3306 :    
3307 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3308 :    
3309 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3310 :    
3311 :     This patch restores SML/NJ's ability to run under win32. There are a
3312 :     number of changes, including fixes for several bugs that had gone
3313 :     unnoticed until now:
3314 :    
3315 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3316 :     trying to run the win32 version from within cygwin.)
3317 :    
3318 :     - There are a number of simple .bat scripts that substitute for their
3319 :     corresponding Unix shell-scripts. (See below.)
3320 :    
3321 :     - The internals of ml-build have been modified slightly. The main
3322 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3323 :     using OS.Process.system, the ML process delegates this task back
3324 :     to the script. Otherwise problems arise in mixed environments such
3325 :     as Cygwin where scripts look and work like Unix scripts, but
3326 :     where OS.Process.system cannot run them.
3327 :    
3328 :     - In CM, the srcpath pickler used native pathname syntax -- which
3329 :     is incorrect in the case of cross-compilation. The new pickle format
3330 :     is independent of platform-specific naming conventions.
3331 :    
3332 :     - Path configuration files (such as lib/pathconfig) can now choose
3333 :     between native and standard syntax. Placing a line of the form
3334 :    
3335 :     standard!
3336 :    
3337 :     into the file causes all subsequent paths to be interpreted using
3338 :     CM standard pathname syntax (= Unix conventions); a line
3339 :    
3340 :     native!
3341 :    
3342 :     switches back to native style. This was needed so that
3343 :     path config files can be written portably, see src/system/pathconfig.
3344 :    
3345 :     - Runtime system:
3346 :    
3347 :     - win32-filesys.c: get_file_time and set_file_time now
3348 :     access modification time, not creation time.
3349 :    
3350 :     - I/O code made aware of new array representation.
3351 :    
3352 :     - Bug fixes in X86.prim.masm.
3353 :    
3354 :     - src/system/makeml made aware of win32. (For use under cygwin
3355 :     and other Unix-environments for windows.)
3356 :    
3357 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3358 :     which caused BinIO.inputAll to fail consistently.
3359 :    
3360 :     .bat scripts:
3361 :    
3362 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3363 :    
3364 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3365 :     applications (sml, ml-yacc, ml-lex).
3366 :     - ml-build.bat: analogous to ml-build.
3367 :     - config\install.bat: Analogous to config/install.sh. This requires
3368 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3369 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3370 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3371 :     and the bootfile hierarchy must have been unpacked under
3372 :     sml.boot.x86-win32.
3373 :     The script is very primitive and does a poor job at error checking.
3374 :     It only installs the base system, ml-lex, and ml-yacc. No other
3375 :     libraries are being installed (i.e., you get only those that
3376 :     are part of the compiler.)
3377 :     - link-sml.bat: analogous to .link-sml, but not currently used
3378 :    
3379 :     Unrelated bug fixes:
3380 :    
3381 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3382 :     types.
3383 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3384 :     otherwise.)

3408 :     Description:
3409 :    
3410 :     Two changes:
3411 :

3413 :     be treated as errors (default is false).
3414 :     2. Cleaned up the *entire* source tree so that CMB.make goes through

3421 :     Description:
3422 :    
3423 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3424 :    
3425 :     This mainly affects the quality of error messages. However, some
3426 :     of the code is now more straightforward than before. (Treatment of
3427 :     the above four constructs in translate.sml is much simpler than
3428 :     the "macro-expansion" that was going on before. Plus, the mach-
3429 :     compiler no longer gets invoked just to be able to compile an
3430 :     if-expression.)
3431 :    
3432 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3433 :     interactive loop.

3440 :    
3441 : blume 2155 Ported the runtime system to cygwin, which uses the unix

3443 :    
3444 : blume 2155 o getnetbyname, getnetbyaddr: these functions seem to be missing in
3445 : allenleung 1327 the Cygwin library.
3446 :     o Ctrl-C handling may be flaky.
3447 :     o Windows system calls and Windows I/O are not supported.
3448 :    
3449 :     A new set of binfiles is located at:
3450 :    
3451 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3452 :    
3453 :     This is only needed for bootstrapping the cygwin version of smlnj.

3496 :     change their identity (e.g., by getting unlinked and recreated by some
3497 :     text editor such as vi). There might be a better/cheaper/cleaner way

3675 :     Tag: blume-20020520-controls
3676 :     Description:
3677 :    
3678 :     - Added ControlUtil structure to control-lib.cm.
3679 :     - Use it throughout.
3680 :     - Used Controls facility to define MLRISC controls (as opposed to
3681 :     registering MLRISC control ref cells with Controls after the fact)
3682 :     - Fixed messed-up controls priorities.
3683 :    
3684 :     * Removed again all the stuff from config/preloads that one wouldn't
3685 :     be able to preload at the time the initial heap image is built.
3686 :     (Many libraries, e.g., CML, do not exist yet at this time. The
3687 :     only libraries that can be preloaded via config/preloads are those
3688 :     that come bundled with the bootfiles.)

3713 :     Description:
3714 :    
3715 :     0. John Reppy made several modifications to the SML/NJ library.
3716 :     In particular, there is a shiny new controls-lib.cm.
3717 :    
3718 :     1. Pushed new controls interface through compiler so that everything
3719 :     compiles again.
3720 :    
3721 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3722 :     SML/NJ library (so that CML compiles again).
3723 :    
3724 :     3. Modified init scripts because XXX_DEFAULT environment variables
3725 :     are no longer with us. (Boot-time initialization is now done
3726 :     using the same environment variables that are also used for
3727 :     startup-time initialization of controls.)

3733 :     Description:
3734 :    
3735 :     All pseudo-ops emitted before the first segment declaration
3736 :     such as TEXT, DATA, and BSS directives are assumed to be global
3737 :     declarations and are emitted first in the assembly file. This is
3738 :     useful in a number of situations where one has pseudo-ops that are not
3739 :     specific to any segment, and also works around the constraint that one
3740 :     cannot have client pseudo-ops in the TEXT segment.
3741 :    
3742 :     Because no segment is associated with these declarations it is
3743 :     an error to allocate any space or objects before the first segment
3744 :     directive and an exception will be raised. However, we cannot make
3745 :     this check for client pseudo-ops.
3746 :    
3747 :     These top level declarations are a field in the CFG graph_info.
3748 :     In theory you can continue to add to this field after the CFG has been
3749 :     built -- provided you know what you are doing;-)

3755 :     Description:
3756 :    
3757 :     A few minor bugfixes:
3758 :    
3759 :     - Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
3760 :     (Bogus printouts for redefined bindings still occur. Compiler
3761 :     bug should no longer occur now. We need to redo the prettyprinter
3762 :     from scratch.)
3763 :    
3764 :     - CM pathname printer now also adds escape sequences for ( and )
3765 :    
3766 :     - commend and docu fixes for ml-nlffi

3771 :     Tag: blume-20020510-erg-textio
3772 :     Description:
3773 :    
3774 :     Applied the following bugfix provided by Emden Gansner:
3775 :    
3776 :     Output is corrupted when outputSubstr is used rather than output.
3777 :    
3778 : blume 2155 The problem occurs when a substring
3779 : blume 1189
3780 :     ss = (s, dataStart, dataLen)
3781 :    
3782 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3783 :     avail bytes of s, starting at index dataStart, are copied into the
3784 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3785 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3786 :     starting this copy at index dataStart+avail in s, the current code
3787 : blume 1189 starts the copy at index avail.
3788 :    
3789 :     Fix:
3790 :     In text-io-fn.sml, change line 695 from
3791 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3792 : blume 2155 to
3793 : blume 1189 val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

3808 :     Tag: blume-20020401-x86div
3809 :     Description:
3810 :    
3811 :     Added full support for div/mod/rem/quot on the x86, using the machine
3812 :     instruction's two results (without clumsily recomputing the remainder)
3813 :     directly where appropriate.
3814 :    
3815 :     Some more extensive power-of-two support was added to the x86 instruction
3816 :     selector (avoiding expensive divs, mods, and muls where they can be
3817 :     replaced with cheaper shifts and masks). However, this sort of thing
3818 :     ought to be done earlier, e.g., within the CPS optimizer so that
3819 :     all architectures benefit from it.
3820 :    
3821 :     The compiler compiles to a fixed point, but changes might be somewhat
3822 :     fragile nevertheless. Please, report any strange things that you might
3823 :     see wrt. div/mod/quot/rem...

3829 :     Description:
3830 :    
3831 :     Fixed my broken div/mod logic. Unfortunately, this means that the
3832 :     inline code for div/mod now has one more comparison than before.
3833 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3834 :     The problem was with quotient = 0, because that alone does not tell
3835 :     us which way the rounding went. One then has to look at whether
3836 :     remainder and divisor have the same sign... :(
3837 :    
3838 :     Anyway, I replaced the bootfiles with fresh ones...

3844 :     Description:
3845 :    
3846 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
3847 :    
3848 :     Primops have changed. This means that the bin/boot-file formats have
3849 :     changed as well.
3850 :    
3851 :     To make sure that there is no confusion, I made a new version.
3852 :    
3853 :    
3854 :     CHANGES:
3855 :    
3856 :     * removed REMT from mltree (remainder should never overflow).
3857 :    
3858 :     * added primops to deal with divisions of all flavors to the frontend
3859 :    
3860 :     * handled these primops all the way through so they map to their respective
3861 :     MLRISC support
3862 :    
3863 :     * used these primops in the implementation of Int, Int32, Word, Word32
3864 :    
3865 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3866 :    
3867 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
3868 :    
3869 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3870 :     floating point
3871 :    
3872 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3873 :     and Real (but Real.abs maps to a separate floating-point-only primop)
3874 :    
3875 :    
3876 :     TODO items:
3877 :    
3878 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
3879 :     instructions because the machine instruction encoder cannot handle
3880 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
3881 :     REM in the first place, and REM is supported by the x86 machine coder.)
3882 :    
3883 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
3884 :     selection phase. (The two can be streamlined because the hardware
3885 :     delivers both quotient and remainder at the same time anyway.)
3886 :    
3887 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
3888 :     (Currently the behavior is inconsistent both across architectures and
3889 :     wrt. the draft Basis spec.)
3890 :    
3891 :     * Word8 should eventually be handled natively, too.
3892 :    
3893 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
3894 :     as if there currently is no execution path that could trigger it in
3895 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
3896 :     hold for things like multiplication and division.)

3901 :     Tag: blume-20020327-mlrisc-divisions
3902 :     Description:
3903 :    
3904 :     Added support for all four division operations (ML's div, mod, quot,
3905 :     and rem) to MLRISC. In the course of doing so, I also rationalized
3906 :     the naming (no more annoying switch-around of DIV and QUOT), by
3907 :     parameterizing the operation by div_rounding_mode (which can be either
3908 :     DIV_TO_ZERO or DIV_TO_NEGINF).
3909 :    
3910 :     The generic MLTreeGen functor takes care of compiling all four
3911 :     operations down to only round-to-zero div.
3912 :    
3913 :     Missing pieces:
3914 :    
3915 :     * Doing something smarter than relying on MLTreeGen on architectures
3916 :     like, e.g., the x86 where hardware division delivers both quotient and
3917 :     remainder at the same time. With this, the implementation of the
3918 :     round-to-neginf operations could be further streamlined.
3919 :    
3920 :     * Remove inlining support for div/mod/rem from the frontend and replace it
3921 :     with primops that get carried through to the backend. Do this for all
3922 :     int and word types.

3927 :     Tag: blume-20020325-divmod
3928 :     Description:
3929 :    
3930 :     I improved (hopefully without breaking them) the implementation of Int.div,
3931 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
3932 :     advantage of the following observations:
3933 :    
3934 :     Let q = x quot y r = x rem y
3935 :     d = x div y m = x mod y
3936 :    
3937 :     where "quot" is the round-to-zero version of integer division that
3938 :     hardware usually provides. Then we have:
3939 :    
3940 :     r = x - q * y where neither the * nor the - will overflow
3941 :     d = if q >= 0 orelse x = q * y then q else q - 1
3942 :     where neither the * nor the - will overflow
3943 :     m = if q >= 0 orelse r = 0 then r else r + y
3944 :     where the + will not overflow
3945 :    
3946 :     This results in substantial simplification of the generated code.
3947 :     The following table shows the number of CFG nodes and edges generated
3948 :     for
3949 :     fun f (x, y) = x OPER y
3950 :     (* with OPER \in div, mod, quot, rem *)
3951 :    
3952 :    
3953 :     OPER | nodes(old) | edges(old) | nodes(new) | edges(new)
3954 :     --------------------------------------------------------

3991 :     Description:
3992 :    
3993 :     1. Changes to FLINT primops:
3994 :    
3995 :     (* make a call to a C-function;
3996 :     * The primop carries C function prototype information and specifies
3997 :     * which of its (ML-) arguments are floating point. C prototype
3998 :     * information is for use by the backend, ML information is for
3999 :     * use by the CPS converter. *)
4000 :     | RAW_CCALL of { c_proto: CTypes.c_proto,
4001 :     ml_args: ccall_type list,
4002 :     ml_res_opt: ccall_type option,
4003 :     reentrant : bool
4004 :     } option
4005 :     (* Allocate uninitialized storage on the heap.
4006 :     * The record is meant to hold short-lived C objects, i.e., they
4007 : blume 2155 * are not ML pointers. With the tag, the representation is
4008 : leunga 1174 * the same as RECORD with tag tag_raw32 (sz=4), or tag_fblock (sz=8)
4009 :     *)
4010 : blume 2155 | RAW_RECORD of {tag:bool,sz:int}
4011 : leunga 1174 and ccall_type = CCALL_INT32 | CCALL_REAL64 | CCALL_ML_PTR
4012 :    
4013 :     2. These CPS primops are now overloaded:
4014 :    
4015 :     rawload of {kind:numkind}
4016 :     rawstore of {kind:numkind}
4017 :    
4018 :     The one argument form is:
4019 :    
4020 :     rawload {kind} address
4021 :    
4022 :     The two argument form is:
4023 : blume 2155
4024 : leunga 1174 rawload {kind} [ml object, byte-offset]
4025 :    
4026 :     3. RAW_CCALL/RCC now takes two extra arguments:
4027 :    
4028 :     a. The first is whether the C call is reentrant, i.e., whether
4029 :     ML state should be saved and restored.
4030 :     b. The second argument is a string argument specifying the name of
4031 :     library and the C function.
4032 :    
4033 :     These things are currently not handled in the code generator, yet.
4034 :    
4035 :     4. In CProto,
4036 :    
4037 : blume 2155 An encoding type of "bool" means "ml object" and is mapped into
4038 :     C prototype of PTR. Note that "bool" is different than "string",
4039 : leunga 1174 even though "string" is also mapped into PTR, because "bool"
4040 :     is assigned an CPS type of BOGt, while "string" is assigned INT32t.
4041 :    
4042 :     5. Pickler/unpicker
4043 :    
4044 :     Changed to handle RAW_RECORD and newest RAW_CCALL
4045 :    
4046 :     6. MLRiscGen,
4047 :    
4048 :     1. Changed to handle the new rawload/rawstore/rawrecord operators.
4049 :     2. Code for handling C Calls has been moved to a new module CPSCCalls,
4050 :     in the file CodeGen/cpscompile/cps-c-calls.sml
4051 :    
4052 :     7. Added the conditional move operator
4053 :    
4054 :     condmove of branch
4055 :    
4056 : blume 2155 to cps. Generation of this is still buggy so it is currently

4064 :    
4065 : blume 2155 Implemented the Ball-Larus branch prediction-heuristics, and
4066 : george 1168 incorporated graphical viewers for control flow graphs.
4067 :    
4068 : george 1171 Ball-Larus Heuristics:
4069 : george 1168 ---------------------
4070 :     See the file compiler/CodeGen/cpscompile/cpsBranchProb.sml.
4071 :    
4072 :     By design it uses the Dempster-Shafer theory for combining
4073 :     probabilities. For example, in the function:
4074 :    
4075 :     fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)
4076 :    
4077 :     the ball-larus heuristics predicts that the n=0 is unlikely
4078 :     (OH-heuristic), and the 'then' branch is unlikely because of the
4079 :     RH-heuristic -- giving the 'then' branch an even lower combined
4080 : george 1171 probability using the Dempster-Shafer theory.
4081 : george 1168
4082 :     Finally, John Reppy's loop analysis in MLRISC, further lowers the
4083 :     probability of the 'then' branch because of the loop in the else
4084 :     branch.
4085 :    
4086 :    
4087 :     Graphical Viewing:
4088 : blume 2155 ------------------
4089 : george 1168 I merely plugged in Allen's graphical viewers into the compiler. The
4090 :     additional code is not much. At the top level, saying:

4094 :     will display the graphical view of the control flow graph just before
4095 :     back-patching. daVinci must be in your path for this to work. If
4096 :     daVinci is not available, then the default viewer can be changed
4097 :     using:
4098 :    
4099 :     Control.MLRISC.getString "viewer"
4100 :    
4101 :     which can be set to "dot" or "vcg" for the corresponding viewers. Of
4102 :     course, these viewers must be in your path.
4103 :    
4104 :     The above will display the compilation unit at the level of clusters,
4105 :     many of which are small, boring, and un-interesting. Also setting:
4106 :    
4107 :     Control.MLRISC.getInt "cfg-graphical-view_size"
4108 :    
4109 :     will display clusters that are larger than the value set by the above.

4133 :     Description:
4134 :    
4135 : blume 2155 1. Recoded the buggy parts of x86-fp.
4136 : leunga 1156
4137 :     a. All the block reordering code has been removed.
4138 :     We now depend on the block placement phases to do this work.
4139 :    
4140 :     b. Critical edge splitting code has been simplified and moved into the
4141 :     CFG modules, as where they belong.
4142 :    
4143 :     Both of these were quite buggy and complex. The code is now much, much
4144 :     simpler.
4145 :    
4146 :     2. X86 backend.
4147 :    
4148 :     a. Added instructions for 64-bit support. Instruction selection for
4149 :     64-bit has not been committed, however, since that
4150 : blume 2155 requires changes to MLTREE which haven't been approved by
4151 : leunga 1156 Lal and John.
4152 :    
4153 : blume 2155 b. Added support for FUCOMI and FUCOMIP when generating code for
4154 : leunga 1156 PentiumPro and above. We only generate these instructions in
4155 :     the fast-fp mode.
4156 :    
4157 : blume 2155 c. Added cases for JP and JNP in X86FreqProps.
4158 :    
4159 : leunga 1156 3. CFG
4160 :    
4161 :     CFG now has a bunch of methods for edge splitting and merging.
4162 :    
4163 :     4. Machine description.
4164 :    
4165 :     John's simplification of MLTREE_BASIS.fcond broke a few machine
4166 :     description things:
4167 :    
4168 :     rtl-build.{sig,sml} and hppa.mdl fixed.
4169 :    
4170 : blume 2155 NOTE: the machine description stuff in the repository is still broken.
4171 :     Again, I can't put my fixes in because that involves
4172 :     changes to MLTREE.

4178 :     Description:
4179 :    
4180 :     Implemented Knuth-Morris-Pratt string matching in PreString and used
4181 :     it for String.isSubstring, Substring.isSubstring, and
4182 :     Substring.position.
4183 :    
4184 :     (Might need some stress-testing. Simple examples worked fine.)
