194 : blume 2692 Date: 2007/06/06 21:45:00 CDT
195 :     Description:
196 :    
197 :     - Aaron: fixed a number of bugs in ml-ulex.
198 :     - Matthias:
199 :     - added CM control "cm.force-tools"; this is false by default;
200 :     when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
201 :     will be forced to run regardless of whether or not their targets
202 :     are up-to-date
203 :     - changed installer code so that config/install.sh will re-build
204 :     heap images for all tools even if those heap images already existed
205 :    
206 :     ----------------------------------------------------------------------
207 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
208 : blume 2688 Date: 2007/06/04 21:21:00 CDT
209 :     Description:
210 :    
211 :     After Aaron Turon's bug fix for ml-ulex (handling the ^ character
212 :     in legacy mode), re-ran the lexer generator on all lex input files
213 :     and committed the results.
214 :    
215 :     This should fix the problem with ckit and nlffi that was reported
216 :     by Vesa A. Norrman.

227 : dbm 2650 Name: Dave MacQueen (dbm@cs.uchicago.edu)
228 :     Date: 2007/05/31 14:55:00 CDT
229 :     Revision: 2650
230 :     Description:
231 :    
232 :     3rd merge of base from primop-branch-3 into the trunk.
233 :     Additional bug fixes included:
234 :    
235 :     * Timer.cpu_timer, etc. type printing corrected (by making
236 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
237 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
238 :     Stefan Monnier)
239 :    
240 :     ----------------------------------------------------------------------
241 : blume 2645 Name: Matthias Blume (http://www.tti-c.org/blume/)
242 :     Date: 2007/05/31 11:40:00 CDT
243 :     Description:
244 :    
245 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
246 :    
247 :     Also, changed the handling of "no core access": When translate.sml
248 :     needs access to a core exception at a time when the core has not
249 :     been set up yet (this only happens when compiling system/smlnj/init/*),
250 :     then don't bother generating the corresponding tests.
251 :    
252 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
253 :     the exception. Unfortunately, that confuses the plambda type checker.
254 :     Moreover, it does not do any good, because at runtime we don't expect
255 :     such an exception to be ever raised. (The code in system/smlnj/init/*
256 :     has to be written very carefully with this in mind!)

259 : mrainey 2639 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
260 :     Date: 2007/05/29
261 :     Description:
262 :    
263 :     Added FSQRT instructions for the AMD64 code generator.
264 :    
265 :     ----------------------------------------------------------------------
266 : blume 2626 Name: Matthias Blume (http://www.tti-c.org/blume/)
267 :     Date: 2007/05/29 19:00:00 CDT
268 :     Description:
269 :    
270 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
271 :     with an explicit test for zero division. This should fixes several
272 :     regressions and makes it possible for downstream optimization phases
273 :     to treat these operations as "pure" when they are applied to unsigned
274 :     operands.
275 :    
276 :     ----------------------------------------------------------------------
277 : mrainey 2622 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
278 :     Date: 2007/05/29
279 :     Description:
280 :    
281 :     Added the new MLRISC code generator for the AMD64. This version,
282 :     in contrast to the previous one, uses SSE registers and instructions
283 :     for all floating-point computations.
284 :

286 : jhr 2613 Name: John Reppy (http://www.cs.uchicago.edu/~jhr)
287 : jhr 2617 Date: 2007/05/29
288 : jhr 2613 Description:
289 :    
290 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
291 :     for bugs #1415 and #1416. We also now correctly handle format characters that
292 :     lie outside the specified set.

295 : blume 2610 Name: Matthias Blume (http://www.tti-c.org/blume/)
296 :     Date: 2007/05/23 22:30:00 CDT
297 :     Description:
298 :    
299 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
300 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
301 :    
302 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
303 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
304 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
305 :     while running CMB.make. The point is that the single symbol
306 :     NO_PLUGINS is definde in all three cases.)
307 :    
308 :     I changed the three locations within the sources that get compiled
309 :     during CMB.make where ml-yacc or ml-lex input is processed: When
310 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
311 :     is bypassed.
312 :    
313 :     When bootstrapping new versions of the compiler, there can be
314 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
315 :     are not available or otherwise not operational. In this case one can
316 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
317 :     do so, the following command should be issued at the interactive
318 :     prompt:
319 :    
320 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
321 :    
322 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
323 :     files that normally would be generated by ml-yacc and ml-lex.
324 :     (Copies of these files are in the repository.)

329 :     Revision: 2603
330 :     Description:
331 :    
332 :     2nd merge of base from primop-branch-3 into the trunk.
333 :     Additional bug fixes included:
334 :     Date.scan and Date.fromString fixed;
335 :     Overloading resolution fixed and some type printing problems corrected.

339 : blume 2589 Date: 2007/05/23 09:50:00 CDT
340 :     Description:
341 :    
342 :     Changed the installation mechanism for CM tool plugins. These are
343 :     just libaries and now get installed like ordinary libaries.
344 :    
345 :     There are now a number of new installation targets that give some
346 :     fine-grain control over what classes and suffixes are known, and what
347 :     they will map to.
348 :     See config/targets for details.
349 :    
350 :     The code that caused plugin installation as part of running a
351 :     tool's "build" script has been removed. (The build script is for
352 :     building, not for installing.)
353 :    
354 :     ----------------------------------------------------------------------
355 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
356 : blume 2578 Date: 2007/05/22 11:50:00 CDT
357 :     Description:
358 :    
359 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
360 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
361 :     CM fail if a shell tool reports a non-success exit status. If
362 :     the control is set to true, then CM will press on after tool failures
363 :     in the event that the target files exist (even though they are
364 :     considered outdated). Turning the control to true can be useful for
365 :     bootstrapping.

368 : adrassi 2570 Name: Aaron Turon (http://www.cs.uchicago.edu/~adrassi)
369 :     Date: 2007/05/19
370 :     Description:
371 :    
372 :     Merge of ml-lpt revisions for 110.64.
373 :    
374 :     The name of several ml-lpt-lib modules has changed:
375 :     Repair => AntlrRepair
376 :     StreamPos => AntlrStreamPos
377 :     ErrHandlerFn => AntlrErrHandler
378 :     EBNF => AntlrEBNF
379 :    
380 :     The ml-antlr specification format has changed: declarations such as
381 :     %tokens and nonterminal definitions can occur *multiple* times in the
382 :     same specification. The semantics are such that each new declaration
383 :     extends the previous ones. This does not apply to %start or %name,
384 :     of course.
385 :    
386 :     Importing a grammar via %import now includes *all* declarations in from
387 :     the imported grammar, except for %name, %entry, and %start. Tokens
388 :     and nonterminals can be dropped using the new %dropping clause of the
389 :     %import directive; the separate %drop and %extend have been removed.
390 :    
391 :     We now allow optional type annotations on nonterminals, using the %nonterms
392 :     directive as in ml-yacc.
393 :    
394 :     The refcell construct is now implemented using SML's regular reference
395 :     cells, so the :== and !! notation has been deprecated.
396 :    
397 :     The ml-antlr tool now does much more checking of specifications, and
398 :     its error messages have been greatly improved. Error repair for
399 :     generated parsers has been completely rewritten, and is now both
400 :     much faster and more accurate.
401 :    
402 :     ml-ulex is now more lenient with escape codes (non-SML-standard
403 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
404 :     Also, character classes may now include a "-" character at the beginning
405 :     as is standard in most other regexp tools.
406 :    
407 :     All of these changes are documented in the user guide, which has
408 :     been updated and improved with this merge.

414 :     Description:
415 :    
416 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
417 :     Significant changes in FLINT and the front end, mostly having to do
418 :     with a reorganized system for handling primops. Various bug fixes
419 :     and improvements in printing signatures.

423 :     Date: 2007/05/02
424 :     Description:
425 :    
426 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
427 :     The ml-antlr specification format has changed: declarations such as
428 :     %tokens and nonterminal definitions can occur *multiple* times in the
429 :     same specification. The semantics are such that each new declaration
430 :     extends the previous ones. Grammar extension constructs have also
431 :     changed. We now allow type annotations on nonterminals. Finally,
432 :     the refcell construct is now implemented using SML's regular reference
433 :     cells, so the :== and !! notation has been deprecated. All of these
434 :     changes will appear in the 110.64 user guide for ml-lpt.
435 :    
436 :     The ml-antlr tool now does much more checking of specifications, and
437 :     its error messages have been greatly improved. There has also been
438 :     some work on the error repair process for generated parsers, but this
439 :     will be further improved in 110.64.

444 :     Revision: r2492
445 :     Description:
446 :    
447 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
448 :     Significant changes in FLINT and the front end, mostly having to do
449 :     with a reorganized system for handling primops. Various bug fixes
450 :     and improvements in printing signatures.

455 :     Description:
456 :    
457 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
458 :     The ml-antlr specification format has changed: declarations such as
459 :     %tokens and nonterminal definitions can occur *multiple* times in the
460 :     same specification. The semantics are such that each new declaration
461 :     extends the previous ones. Grammar extension constructs have also
462 :     changed. We now allow type annotations on nonterminals. Finally,
463 :     the refcell construct is now implemented using SML's regular reference
464 :     cells, so the :== and !! notation has been deprecated. All of these
465 :     changes will appear in the 110.64 user guide for ml-lpt.
466 :    
467 :     The ml-antlr tool now does much more checking of specifications, and
468 :     its error messages have been greatly improved. There has also been
469 :     some work on the error repair process for generated parsers, but this
470 :     will be further improved in 110.64.

475 :     Description:
476 :    
477 :     More Basis fixes: The Char.fromString (etc.) functions did not handle
478 :     the "\uxxxx" escape sequence. There is still an outstanding bug with
479 :     String.fromString the tail is a format escape. I added a comment to
480 :     this effect in Basis/Implementation/string.sml.

559 :     Description:
560 :    
561 :     Added preliminary support in MLRISC for Staged Allocation, a technique
562 :     for specifying calling conventions (see
563 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
564 :     Initially, we plan to use this code to generate C calls for the AMD64.
565 :    
566 :     The staged allocation code base resides in MLRISC/staged-allocation,
567 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

573 :    
574 :     Bug fix: when SaveCState was called with two values to save, a subsequent

587 :    
588 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
589 :     of the range -128 ... 127. I've changed the code so that the range
590 :     check is disabled. Only the low order 8 bits of the immediate operand

631 :     Date: 2007/01/31
632 :     Description:
633 :    
634 :     Brought ml-lpt manual up-to-date with the code. Many minor
635 :     improvements to the tools, and a few minor bugfixes. Prepared
636 :     ml-lpt-lib for integration with new UTF8 structure. Changed
637 :     the interface for creating streams in ml-ulex (we now support
638 :     stream creation from several kinds of sources). Overall, the
639 :     tools are now quite stable, and their interfaces are unlikely to
640 :     change in a way that would break compatibility. More work,
641 :     however, is needed in the documentation.

646 :     Description:
647 :    
648 :     Implemented library installer. Moved CM plugin code for
649 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
650 :     their respective trees. Implemented CM plugin for ml-ulex
651 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
652 :     and ml-antlr.
653 :    
654 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
655 :     CM tools. (It turns out to be too messy to do otherwise because
656 :     there is too much code that during installation relies on the presence
657 :     of these tools -- resulting in a tricky ordering problem.)

662 :     Description:
663 :    
664 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
665 :     Modified CM's startup code to use shiftArgs as it processes
666 :     command line arguments. This way, the init code in each .sml-file
667 :     or library that is mentioned at the top level will see only
668 :     those arguments that have not yet been processed at this point.
669 :     In other words, the init code can "seize control" and process the
670 :     remaining command line.

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

727 :    
728 :     Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to

737 :     Description:
738 :    
739 :     Added code to CM's "standard shell tool" implementation which
740 :     causes it to tolerate (with a warning) the situation where the shell
741 :     command fails (e.g., due to the shell command's non-existence)
742 :     as long as all target files exist.
743 :    
744 :     This makes it possible to, e.g., build ml-yacc from sources even if
745 :     svn checkout messed up the time stamps on files in such a way that
746 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
747 :     be needed to re-process yacc.grm, but obviously it might not yet be
748 :     available at that time.)

754 :    
755 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and

757 :     in the SML Basis specification too.

788 :     Description:
789 :    
790 :     New working release (110.60). NEW BOOTFILES!
791 :    
792 :     This is the first subversion-hosted release. There are also changes
793 :     to the directory layout. Here is a table:
794 :    
795 :     (All pathnames are relative to the SML/NJ "root" directory.)
796 :    
797 :     config -> config
798 :    
799 :     src/cm -> base/cm
800 :     src/compiler -> base/compiler
801 :     src/runtime -> base/runtime
802 :     src/system -> base/system
803 :    
804 :     src/cm/pgraph -> pgraph
805 :    
806 :     src/READMES -> base/READMES
807 :     src/$notefile -> base/NOTES/$notefile
808 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
809 :     MACOSXINSTALL WININSTALL
810 :    
811 :     src/smlnj-lib -> smlnj-lib
812 :     src/MLRISC -> MLRISC
813 :     ckit -> ckit
814 :     src/cml -> cml
815 :     src/eXene -> eXene
816 :     src/heap2asm -> heap2asm
817 :     src/lexgen -> lexgen
818 :     src/ml-burg -> ml-burg
819 :     src/ml-lex -> ml-lex
820 :     src/ml-yacc -> ml-yacc
821 :     src/ml-nlffi-lib -> nlffi/lib
822 :     src/ml-nlffigen -> nlffi/gen
823 :     src/smlnj-c -> smlnj-c
824 :     src/tools/TraceDebugProf -> trace-debug-profile
825 :    
826 :     In addition, there is also a new
827 :    
828 :     ml-lpt
829 :    
830 :     directory containing two new program generator tools: ml-ulex and
831 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
832 :     LL(k) parser generator). These tools are currently "beta-quality"
833 :    
834 :     The latest versios of the sources can now be obtained anonymously
835 :     via subversion. For this, it is useful to first check out
836 :    
837 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
838 :    
839 :     and put the resulting directory on your shell's PATH. This provides
840 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
841 :     and refresh-all.sh.
842 :    
843 :     To create a freshly checked-out copy of the sources, do
844 :    
845 :     checkout-all.sh [dir]
846 :    
847 :     where dir is the optional SML/NJ root directory (default is ".").
848 :    
849 :     This creates the above directory layout. Each subdirectory of
850 :     the root is under individual subversion control. The stat-all.sh
851 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
852 :     each of these subtrees.

857 :     Description:
858 :    
859 :     Reorganized directory layout.
860 :    
861 :     This is a temporary solution, more reorganization is to come.
862 :    
863 :     The basic idea is to have a number of toplevel trees, each corresponding
864 :     to a well-defined part of the overall system. Each part can be
865 :     maintained individually, even in separate source repositories,
866 :     although currently we still serve everything out of the main
867 :     smlnj-gforge tree.
868 :    
869 :     Installer and and scripts have been updated to reflect the new
870 :     layout. The installer (base/src/system/smlnj/installer) is now
871 :     "scriptable" to avoid burning too much knowledge about the
872 :     layout into SML source code. The main script used by the installer
873 :     is in config/actions.
874 :    
875 :     The main change is that many of the subdirectories of what used to
876 :     be known as "src" have moved to the toplevel. The "src" directory
877 :     itself has moved down into a subtree called "base". (We may eventually
878 :     get rid of the extra level of indirection represented by "src".)
879 :    
880 :     The layout is now as follows:
881 :    
882 :     toplevel tree name | default repository
883 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
884 :     -------------------+----------------------------------------------------
885 :     config | $gf/config/trunk
886 :     |
887 :     base | $gf/sml/trunk
888 :     |
889 :     smlnj-lib | $gf/smlnj-lib/trunk
890 :     MLRISC | $gf/MLRISC/trunk
891 :     |
892 :     ml-yacc | $gf/ml-yacc/trunk
893 :     ml-lex | $gf/ml-lex/trunk
894 :     ml-burg | $gf/ml-burg/trunk
895 :     lexgen | $gf/lexgen/trunk
896 :     heap2asm | $gf/heap2asm/trunk
897 :     |
898 :     cml | $gf/cml/trunk
899 :     eXene | $gf/eXene/trunk
900 :     ckit | $gf/ckit/trunk
901 :     nlffi | $gf/nlffi/trunk
902 :     |
903 :     smlnj-c | $gf/smlnj-c/trunk
904 :    
905 :     In $gf/admin there are a few useful shell scripts for checking out
906 :     and maintaining the entire collection of trees:
907 :    
908 :     admin/checkout-all.sh [dir]
909 :     -- optionally creates dir and checks out all trees from their
910 :     default repositories; if dir is missing, checkout into .
911 :     admin/refresh-all.sh [dir]
912 :     -- looks at all trees (from the above list) in dir (default: .)
913 :     and runs "svn update" if the tree exists and is under
914 :     subversion control;
915 :     non-existing or non-subversion trees are skipped
916 :     admin/stat-all.sh [dir]
917 :     -- like refresh-all.sh, but runs "svn stat" instead

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

1064 :    
1065 :     Hooked code for Darwin-specific Intel ABI into main compiler.
1066 :     (This is a temporary solution which relies on the fact that the

1097 :     Description:
1098 :    
1099 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1100 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1101 : blume 2155 at the time when config/preloads is processed, the library has to
1102 : mblume 1878 be referred to by another name. In 110.57 this would be
1103 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1104 :     to be valid as well.)

1160 :     Description:
1161 :    
1162 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1163 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1164 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1165 :     it. Instead, it has the status of "user code", so it should use
1166 :     $/basis.cm to refer to the Basis library. (At least that's true for
1167 :     the purpose of bootstrapping the previous change. In the future it
1168 :     might make sense to have versiontool.cm refer to
1169 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1170 :     compiler itself uses.)
1171 :    
1172 :     Also patched src/system/testml to have it activate those extra anchor
1173 :     bindings in config/extrapathconfig.

1178 :     Tag: blume-22051115-libraries
1179 :     Description:
1180 :    
1181 :     This change affects the way the following libraries are tied into
1182 :     the system:
1183 :    
1184 :     $/basis.cm
1185 :     $/smlnj-lib.cm
1186 :     $/pp-lib.cm
1187 :     $/controls-lib.cm
1188 :     $/html-lib.cm
1189 :     $/ml-yacc-lib.cm
1190 :    
1191 :     These libraries are now internally (as seen from the source code
1192 :     of the implementation itself) known by the following names:
1193 :    
1194 :     $smlnj/basis/basis.cm
1195 :     $smlnj/smlnj-lib/smlnj-lib.cm
1196 :     $smlnj/smlnj-lib/pp-lib.cm
1197 :     $smlnj/smlnj-lib/controls-lib.cm
1198 :     $smlnj/smlnj-lib/html-lib.cm
1199 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1200 :    
1201 :     This makes it possible to work with code that requires different
1202 :     versions of these libraries, and which refers to these libraries using
1203 :     their "default" names (i.e., the first set of names above). In other
1204 :     words, one can un-define or re-define those default names without
1205 :     compromising the proper functioning of the compiler itself.
1206 :    
1207 :     A similar procedure had already been performed for several of the
1208 :     MLRISC libraries that are linked into the compiler. I did some
1209 :     cleanup on this code.
1210 :    
1211 :     A new file in the config directory (named extrapathconfig) is
1212 :     responsible for setting up path anchors that the compiler itself does
1213 :     not need, but that are typically required by user code.

1392 :     Tag: blume-20050516-redump-heap
1393 :     Description:
1394 :    
1395 :     Added mechanism for re-creating a heap file for the interactive system
1396 :     after configuration variables have been changed.
1397 :    
1398 :     CM.redump_heap : string -> unit
1399 :    
1400 :     This is much like SMLofNJ.exportML, but starting from the resulting
1401 : blume 2155 heap does not return to the caller of CM.redump_heap but
1402 : mblume 1792 restarts the interactive system from scratch. The original call of
1403 :     CM.redump_heap does not return but ends the interactive session.
1404 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1405 :    
1406 :     Internally, redump_heap winds the dynamic execution context back to
1407 :     the point where the original heap image was created and re-executes
1408 :     the heap image generation code in the boot code.

1524 :     Tag: blume-20050114-heap2exec
1525 :     Description:
1526 :    
1527 :     Implemented new (but still experimental) heap2exec facility. This is
1528 :     tested under Mac OS X and should work under Linux (will test shortly).
1529 :     It will probably also work on the Sparc (will test some time later).
1530 :    
1531 :     - removed old "HACKED_STANDALONE" hack from runtime
1532 :    
1533 :     To be able to test this, uncomment the request for "heap2asm" in
1534 :     config/targets prior to installation. (Notice that this is different
1535 :     from "heap2exec" mentioned below. Not a typo.)
1536 :    
1537 :     To perform an actual test, run the command
1538 :    
1539 :     $ bin/heap2exec heapfile execfile
1540 :    
1541 :     (You can put heap2exec on your shell's path.)
1542 :    
1543 :     For example, run
1544 :    
1545 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1546 :    
1547 :     This will create a standalone executable called "mly" which you can
1548 :     then invoke directly as a command.

1573 :     (The parameter-passing part of the picture has not complete. But
1574 :     data structure access seems to work.)
1575 :    
1576 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1577 :     (On the Mac, it is big-endian. And that's currently our only
1578 :     PPC platform.)

1678 :     Modified implementation of structure Atom to avoid extracting
1679 :     strings from substrings unless necessary.

1693 :     Tag: blume-20041124-position
1694 :     Description:
1695 :    
1696 :     The compiler can now be compiled in a mode that makes structure Position
1697 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1698 :     for the time being.
1699 :    
1700 :     To enable 64-bit positions, use the following procedure:
1701 :    
1702 :     1. Start sml
1703 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1704 :     3. Type
1705 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1706 :     4. Run CMB.make() as usual.
1707 :    
1708 :     This is barely tested. The only test so far was a little SML program
1709 :     counting the number of characters in an 8-gigabyte file by
1710 :     reading it character-by-character. That test was successful.
1711 :    
1712 :     In support of 64-bit positions, a number of new functions have been
1713 :     added to the runtime system.

1757 :     The date string is generated at bootstrap time (during makeml).
1758 :    
1759 :     - In a previous commit, fixed a minor issue with how polyequal is being
1760 :     translated. In particular, the code now "looks through" abstractions.
1761 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1762 :     more efficient code. Important examples for where this matters are
1763 :     the new int64 and word64 types.

1782 :     but for the time being they don't even make sense because LargeWord is
1783 :     32-bit wide.)

1786 :     are still missing.

1792 :     Description:
1793 :    
1794 :     Structure Word64 is now (almost) complete, word literals and patterns
1795 :     seem to work. There are a few odd pieces missing. In particular,
1796 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1797 :     at the moment.
1798 :    
1799 :     Making Word64 official would mean that LargeWord becomes Word64. But
1800 :     this requires extreme care because most word-word conversions have to
1801 :     go through LargeWord, so making a mistake means loss of efficiency or
1802 :     worse. Eventually there will be a solution similar to (but actually
1803 :     simpler than) what I did with IntInf.

1838 :     - Made corresponding changes to config/install.sh and config/unpack.
1839 :     - Default contents of config/srcarchiveurl uses $VERSION and
1840 :     normally does not have to be edited to reflect a version change.
1841 :    
1842 :     (As a result, a version change can be done by just editing
1843 :     config/version, the rest is now automatic.)

1883 :     Tag: blume-20041020-standalone-backtrace
1884 :     Description:
1885 :    
1886 :     Added a mechanism for getting back-trace information from standalone
1887 :     programs. Here is how it works:
1888 :    
1889 :     1. The part of the program from which you want to get backtrace
1890 :     information (usually the whole program) should be wrapped with
1891 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
1892 :     main program could be modified from something like
1893 :    
1894 :     fun main (pgm, args) = ...
1895 :    
1896 :     to
1897 :    
1898 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1899 :    
1900 :     2. To be able to access BackTrace.monitor, you have to add
1901 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
1902 :     main function.
1903 :    
1904 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1905 :     CM might have created in the past for your project).
1906 :    
1907 :     4. Build the system using this command line:
1908 :    
1909 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1910 :     myprog.cm MyProg.main myprog
1911 :    
1912 :     instead of the usual
1913 :    
1914 :     ml-build myprog.cm MyProg.main myprog
1915 :    
1916 :     I changed a library name:
1917 :    
1918 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1919 :    
1920 :     New libraries:
1921 :    
1922 :     $smlnj-tdp/back-trace.cm
1923 :     -- when loaded causes the back-trace plugin to be installed
1924 :     $smlnj-tdp/coverage.cm
1925 :     -- when loaded causes the coverage plugin to be installed

1941 :     Description:
1942 :    
1943 :     * Test coverage tool added!
1944 :     * Further reorganization of tracing-, debugging-, and profiling support:
1945 :    
1946 :     - moved original BTImp -- now called BackTrace -- into a separate
1947 :     library called $/trace-debug-profile.cm
1948 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
1949 :     - only the instrumentation mechanism is now left in the compiler proper
1950 :     - BackTrace module is a plugin which is NOT plugged in by default
1951 :     - Coverage module is another such plugin
1952 :    
1953 :     To get the benefits of any of these plugin modules, the code in
1954 :     question must be compiled with tdp instrumentation turned on. This
1955 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
1956 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1957 :    
1958 :     Plugins are selected at link time. (Pre-compiled instrumented code
1959 :     can be re-loaded with different plugins in effect.) When an
1960 :     instrumented module is linked, whatever plugins are at that time
1961 :     enabled will come into effect for that module.
1962 :    
1963 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
1964 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
1965 :     To enable the coverage plugin, load the same library and invoke
1966 :     Coverage.install().
1967 :    
1968 :     Back-traces are generated automatically on uncaught exceptions and
1969 :     when the code in question explicitly invokes BackTrace.trigger().
1970 :    
1971 :     Coverage (and execution frequency-) information must be queried
1972 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2089 :     Tag: blume-20040929-autoversion
2090 :     Description:
2091 :    
2092 :     Implemented some CM magic to have
2093 :     file src/compiler/TopLevel/main/version.sml
2094 :     generated automagically.
2095 :     The version is taken from two files: config/version and config/release.
2096 :     The first is expected to contain a two-part version number such as 110.49.
2097 :     The second should contain a single number, but it may be missing.
2098 :    
2099 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2100 :     time the version tool is loaded (which is the first time you say CMB.make),
2101 :     then the tool will increment the value stored in config/release every
2102 :     time CMB.make is invoked.
2103 :    
2104 :     The binfile format is now insensitive to anything beyond the first
2105 :     two components of a version number, so bumping the release does not render
2106 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2107 :     during development without invalidating existing binfiles.
2108 :    
2109 :     In any case, every CMB.make updates the date information in version.sml.
2110 :     (This is the date that is printed in the banner.)

2117 :    
2118 :     Some cleanup of the controls code.

2122 : mblume 1633 Date: 2004/09/27 22:08:00 CDT
2123 :     Tag: blume-20040927-controls
2124 :     Description:
2125 :    
2126 :     Added two pieces of functionality to the Controls interface:
2127 :    
2128 :     1. val save'restore: 'a control -> unit -> unit
2129 :    
2130 :     grabs the current value of the control in stage 1 and restores it
2131 :     in stage 2.
2132 :    
2133 :     2. val set' : 'a control * 'a -> unit -> unit
2134 :    
2135 :     stores the given value into the control in stage 2 (i.e., delayed)
2136 :     but does all error checking in stage 1.
2137 :     (This is for string controls that need to do parse their argument --
2138 :     something that might fail. In some cases, notably in CM, one
2139 :     already knows the intended argument but wants to delay the actual
2140 :     assignment until a time when error recovery would be more difficult.)
2141 :    
2142 :     Changed the handling of controls in tool arguments to classes "sml" and
2143 :     "lazysml":
2144 :     - use Controls.save'restore as a more robust way of restoring the
2145 :     old value (in particular: without having to re-parse the string)
2146 :     - use controls to handle the "overload" keyword in the init group
2147 :     (I believe this change actually fixes a long-standing obscure bug.)

2152 :     Tag: blume-20040927-lazysml
2153 :     Description:
2154 :    
2155 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2156 :     difference to "sml" is that compilation is done with Control.lazysml
2157 :     set to true. A source of class "lazysml" is automatically recognized
2158 :     by a file name suffix of ".lml".
2159 :    
2160 :     In addition to the above feature, the original class "sml" now also
2161 :     supports a tool argument "lazy" which has the same effect. As a
2162 :     result, the following three lines are equivalent:
2163 :    
2164 :     foo.sml : lazysml
2165 :     foo.sml : sml (lazy)
2166 :     foo.sml (lazy)
2167 :    
2168 :     The setting goes into effect both during parsing and during
2169 :     compilation. The original setting is restored right after parsing and
2170 :     after compilation, respectively.
2171 :    
2172 :     In addition to all the above, there is also a general mechanism to set
2173 :     ANY of the "controls" that are available at the command line via
2174 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2175 :     apply as well. (In fact, "lazy" is implemented as a special case of
2176 :     the general mechanism.)
2177 :    
2178 :     The .cm file syntax uses a new keyword tool argument called "with".
2179 :     There are several ways of indicating the desired settings:
2180 :    
2181 :     foo.sml (with:parser.quotations=true)
2182 :     foo.sml (with:(name:parser.quotations value:true))
2183 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2184 :     foo.sml (with:(name1=value1 name2=value2 ...))
2185 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2186 :    
2187 :     etc.
2188 :    
2189 :     Another possible abbreviation is to leave out the =v or value:v part
2190 :     if the name refers to a boolean control (in which case the value is
2191 :     taken to be true). Thus, one could get lazy sml also by saying:
2192 :    
2193 :     foo.sml (with:parser.lazy-keyword=true)
2194 :     foo.sml (with:parser.lazy-keyword)
2195 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2196 :     foo.sml (with:(name:parser.lazy-keyword))

2493 :     Description:
2494 :    
2495 :     - use paramAlloc to report c-calls with too many arguments
2496 :     (for PPC version where parameter area is pre-allocated)
2497 :     - added ccall_maxargspace to machspec (to implement the above)
2498 :     - made "make" commend in CM's "make" tool configurable
2499 :     - added option (default: on) for passing the name of the SML/NJ's "bin"
2500 :     directory to "make"; the call looks like this:
2501 :    
2502 :     make <options> SMLNJ_BINDIR=<dir> <target>
2503 :    
2504 :     This can be used by the Makefile to, e.g., pick the "right" version

2514 :     NLFFI under Mac OS X now working (sort of). This is largely untested,
2515 :     though.
2516 :    
2517 :     Note: 1. You have to make a new, clean build of the runtime system.
2518 :     2. There are new BOOTFILES, you have to use them!
2519 :     (Doing the bootstrap process yourself would be *very* painful!
2520 :     If you absolutely have to do it, build the system under
2521 :     a different architecture and then cross-compile.)
2522 :    
2523 :     Version bumped to 110.46.1 to account for runtime data format changes.

2547 :     Tag: blume-20040617-timer-unix
2548 :     Description:
2549 :    
2550 :     Changed the interface of structures Timer and Unix to match the most
2551 :     recent Basis spec.
2552 :    
2553 :     In the case of Unix there still seems to be an open/weird issue:
2554 :    
2555 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2556 :     fresh streams whenever they are called -- as opposed to have them
2557 :     return the same stream every time. This design is supposed to
2558 :     prevent space leaks caused by proc values hanging on to streams.
2559 :    
2560 :     The reap function, on the other hand, is supposed to close the
2561 :     streams. This cannot be done without having a handle on the
2562 :     stream in proc after all...
2563 :    
2564 :     I took the liberty to implement the following stopgap solution:
2565 :    
2566 :     The proc value hangs on to the most recently created stream(s).
2567 :     Reap closes those. If either or both of the two streams hadn't
2568 :     been created at all yet, then reap will close the corresponding
2569 :     file descriptors directly.
2570 :    
2571 :     PS: I don't understand the original space leak argument anymore. If
2572 :     a proc hangs on to the imperative stream, then I/O operations on those
2573 :     will advance the state of the cached stream and avoid the space leak.

2586 :     Tag: blume-20040525-group-owner
2587 :     Description:
2588 :    
2589 :     CM now ignores (but still accepts) the "owner" information in group
2590 :     descriptions. The owner of a group is its next enclosing
2591 :     library. Each group must have a unique owner. (There is a virtual
2592 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2593 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2594 :     and CM would check that such a declaration is correct. The new scheme
2595 :     is to have CM check that for each group there is precisely one owning
2596 :     library.
2597 :    
2598 :     The advantage of the new scheme is that the programmer no longer needs
2599 :     to maintain the somewhat annoying owner information. The downside is
2600 :     that CM cannot enforce the ownership rule across multiple runs of
2601 :     CM.make. Fortunately, enclosing the same group in two different
2602 :     libraries A and B which are not part of the same program does not
2603 :     cause real problems.

2613 :     compiled correctly.)
2614 :    
2615 :     Also, included a minor addition to ml-build.bat analogous to what was
2616 :     done in blume-20040519-ml-build.

2622 :     Description:
2623 :    
2624 :     Arranged for ml-build to clean up after itself a little bit better.
2625 :     The script generates a temporary SML source file and compiles it using
2626 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
2627 :     gets rid of those at the end, so they don't accumulate under .cm.
2628 :    
2629 :     This required a minor change to install.sh because the name of the
2630 :     metadata directory (default: .cm) is actually configurable at
2631 :     installation time.

2648 :     Added previously missing support for many socket-related functions
2649 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
2650 :     for the voluminous patch!
2651 :    
2652 :     (I have not tested this patch under win32 yet.)
2653 :    
2654 : mblume 1490 Here is David's e-mail:
2655 :    
2656 :     Hi,
2657 :    
2658 :     Attached to this email you find a diff against sml/nj 110.45
2659 :     that will enable socket support under Windows.
2660 :    
2661 :     To apply the patch (using unix or cygwin)
2662 :     1) gunzip runtime.diff.gz
2663 :     2) "cd" into "src/runtime" in the source tree of a fresh
2664 :     110.45 installation.
2665 :     3) patch -p 1 < [your/path/to]runtime.diff
2666 :    
2667 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2668 :     I only ran a few tests for basic socket client functionality
2669 :     (which worked fine). Especially the functions that use ioctl
2670 : mblume 1490 are not tested at all and might not work (see below).
2671 :    
2672 :     I implemented this since we want to move to a newer version of sml/nj
2673 :     but need socket support in order to use it. This is the first time I
2674 :     even had a look at the sml/nj source, so please review my changes
2675 :     before making this part of the distribution! Here are a few issues
2676 : blume 2155 that I think might be better for someone to solve who is more
2677 : mblume 1490 familiar with the sml/nj source (and socket programming):
2678 :    
2679 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2680 :     exception since I could not figure out what the windows equivalent
2681 :     of these functions is
2682 :    
2683 :     - In sockets-osdep.h there are a some #include statements that are
2684 :     only used in a few files that include sockets-osdep.h
2685 :    
2686 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2687 :     does not process its return value since I don't know how to
2688 :     report an error upwards.
2689 :    
2690 :     - It would probably be good to have a call to WSACleanup() when
2691 : blume 2155 the library is unloaded (if there is such a possibility).
2692 : mblume 1490 Otherwise I think Windows will take care of this automatically
2693 :     when the process finishes.
2694 :    
2695 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2696 :     no idea if that is actually the proper replacement on Windows.
2697 :    
2698 :     - All these issues are marked in the code by "FIXME" comments.
2699 :    
2700 : blume 2155 We use sml/nj extensively in our products and are quite happy
2701 :     with it. I hope this contribution will help you.
2702 : mblume 1490
2703 :     Keep up the good work!

2874 :     backward-compatibility feature when I first introduced the new CM.
2875 :     Now that things have been stable for a long time and going back to the
2876 :     old CM is not an option, there is no reason to keep it around.)

2926 :     Description:
2927 :    
2928 :     I modified the read-eval-print loop so that the autoloader gets
2929 :     invoked whenever the prettyprinter tries to look up a symbol that
2930 :     is not currently defined in the toplevel environment but which
2931 :     appears in CM's autoload registry. As a result, we see far fewer of
2932 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
2933 :    
2934 :     In addition to this I tried to clean up some pieces of the Basis
2935 :     implementation (e.g., Socket, Word8Array) in order to prevent other
2936 :     instances of these ?.Foo.Bar.xxx names from being printed.
2937 :    
2938 :     The mechanism that picks names for types still needs some work, though.
2939 :     (Right now it seems that if there is a type A.t which is defined to
2940 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
2941 :     "?.B.u" although the perhaps more sensible solution would be to use
2942 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
2943 :     a chain of DEFtycs not farther than there are corresponding toplevel
2944 :     names in the current environment.)

2950 :     Description:
2951 :    
2952 :     Another installer tweak: All the ML code for the installer is now
2953 :     compiled during CMB.make and put into a little library called
2954 :     $smlnj/installer.cm. The installation then simply invokes
2955 :    
2956 :     sml -m $smlnj/installer.cm
2957 :    
2958 :     and everything happens automagically.
2959 :    
2960 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
2961 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
2962 :     and BINDIR.
2963 :    
2964 :     The new scheme guarantees that the ML code responsible for the installation
2965 :     is in sync with the APIs of the main system. Also, the installer is
2966 :     somewhat faster because the installer script is precompiled.

2983 :     Tag: blume-20030924-sockets
2984 :     Description:
2985 :    
2986 :     1. Fixed SOCKET API and implementation to match Basis spec.
2987 :     This required changing the internal representation of sockets to one
2988 :     that remembers (for each socket file descriptor) whether it is currently
2989 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
2990 :     call is made only if the state actually needs to change).
2991 :    
2992 :     2. OS-specific details of sockets were moved into separate files, thus
2993 :     making it possible to unify the bulk of the socket implementations
2994 :     between Unix and Win32.
2995 :    
2996 :     3. CML's socket API changed accordingly.
2997 :     (Note that we need to remove non-blocking functions from this API
2998 :     since they are redundant in the case of CML!)
2999 :    
3000 :     4. CML's socket implementation now makes use of non-blocking functions
3001 :     provided by Basis, thus removing all OS-dependent code from this part
3002 :     of CML.
3003 :    
3004 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3117 :     Description:
3118 :    
3119 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3120 :     Modified config/install.bat to take advantage of it. Also modified
3121 :     config/install.sh (and called it config/new-install.sh) to take advantage
3122 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3123 :     independent.)
3124 :    
3125 :     The installer can now install everything under Win32

3127 :    
3128 :     Other changes:
3129 :    
3130 :     - made CML compile again under Win32
3131 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3132 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3133 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3134 :     same as type int; under Win32 it isn't
3135 :     - fixed some slice-related problems in the win32-specific parts of CML
3136 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3137 :     (under Win32, the volume name is case-insensitive, and the
3138 :     OS.Path code compares volume names for equality)

3155 : mblume 1350 Description:
3156 :    
3157 :     1. Changed interface to vectors and arrays in Basis to match
3158 :     (draft) Basis spec.
3159 :     2. Added signatures and implementations of slices according to
3160 :     Basis spec.
3161 :     3. Edited source code throughout the system to make it compile again
3162 :     under 1. and 2. (In some cases code had to be added to have it
3163 :     match the new signatures.)
3164 :     4. MLRISC should be backward-compatible: the copies of the originals
3165 :     of files that needed to change under 3. were retained, the .cm files
3166 :     check the compiler version number and use old versions when
3167 :     appropriate.
3168 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3169 :     dirstream -> string option (in accordance with Basis spec).
3170 :     6. When generating code that counts lines, ml-lex used function
3171 :     CharVector.foldli, taking advantage of its old interface.
3172 :     This has been replaced with the corresponding code from
3173 :     CharVectorSlice. (html-lex must be re-lexed!)
3174 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3175 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3176 :     8. Removed temporary additions (fromInternal, toInternal) from the
3177 :     (now obsolete) IntInf in smlnj-lib/Util.
3178 :     9. Cleaned up structure Byte.
3179 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3180 :     Cleaned/corrected implementation of Date.
3181 :     (Still need to check for correctness; implement better canonicalizeDate.)
3182 :     11. Added "scan" to signature IEEE_REAL.
3183 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3184 :     mod and rem when second operand is 2 (for parity checks).]
3185 :     13. Changed representation of type Time.time, using a single IntInf.int
3186 :     value counting microseconds. This considerably simplified the
3187 :     implementation of structure Time. We now support negative time
3188 :     values; scan and fromString handle signs.
3189 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3190 :     ArraySlice).

3195 :     Tag: blume-20030828-intinf
3196 :     Description:
3197 :    
3198 :     This is a major update which comes with a version number bump
3199 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3200 :     and an implementation of IntInf in the Basis.
3201 :    
3202 :     There are a fairly large number of related changes and updates throughout
3203 :     the system:
3204 :    
3205 :     Basis:
3206 :     - Implemented IntInf.
3207 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3208 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3209 : mblume 1347 - Added FixedInt as a synonym for Int32.
3210 :    
3211 :     compiler:
3212 :     * Added support for a built-in intinf type.
3213 :     - literals
3214 :     - pattern matching
3215 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3216 :     - overloading on literals and operations
3217 :    
3218 :     This required adding a primitive type intinf, some additional
3219 :     primops, and implementations for several non-trivial intinf
3220 :     operations in Core. (The intinf type is completely abstract
3221 :     to the compiler; all operations get delegated back to the Core.)
3222 :    
3223 :     * Intinf equality is handled by polyequal. However, the compiler
3224 :     does not print its usual warning in this case (since polyequal
3225 :     is the right thing to do there).
3226 :    
3227 :     * Improved the organization of structure InlineT.
3228 :    
3229 :     * A word about conversion primops:
3230 :     If conversions involving intinf do not cancel out during
3231 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3232 : mblume 1347 Since all core access must be resolved already during the FLINT
3233 :     translate phase, it would be too late a the time of CPS contract
3234 : mblume 1348 to add new Core calls. For this reason, conversion primops
3235 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3236 :     they are supposed to convert, and 2. the Core function that
3237 :     can help with this conversion if necessary. If CPS contract
3238 : mblume 1348 eliminates a primop, then the associated Core function becomes
3239 :     dead and goes away. Intinf conversion primops that do not get
3240 :     eliminated by CPS contract get rewritten into calls of their
3241 :     core functions by a separate, new phase.
3242 : mblume 1347
3243 :     interactive system:
3244 :     - Control.Print.intinfDepth controls max length of intinf constants
3245 :     being printed. (Analogous to Control.Print.stringDepth.)
3246 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3247 :     duplicates; replaced some of the code with code that makes better
3248 :     use of library functionality.
3249 :    
3250 :     CM:
3251 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3252 :     are no longer silent.
3253 :    
3254 :     CKIT:
3255 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3256 :     in favor of LargeInt -- which is now the same as IntInf.
3257 :     CKIT-knowledgable people should check whether this is what's
3258 :     intended and otherwise change things back to using Int32 or
3259 :     FixedInt.

3271 :    
3272 :     Merging changes from the mcz-branch development branch into trunk.
3273 :     These changes involve replacement of the emulated old prettyprinter
3274 :     interface with direct use of the SML/NJ Lib PP library, and fixing
3275 :     of a couple of bugs (895, 1186) relating to error messages. A new
3276 :     prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
3277 :     has been added.

3282 :     Tag: blume-20030811-windows
3283 :     Description:
3284 :    
3285 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3286 :    
3287 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3288 :    
3289 :     This patch restores SML/NJ's ability to run under win32. There are a
3290 :     number of changes, including fixes for several bugs that had gone
3291 :     unnoticed until now:
3292 :    
3293 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3294 :     trying to run the win32 version from within cygwin.)
3295 :    
3296 :     - There are a number of simple .bat scripts that substitute for their
3297 :     corresponding Unix shell-scripts. (See below.)
3298 :    
3299 :     - The internals of ml-build have been modified slightly. The main
3300 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3301 :     using OS.Process.system, the ML process delegates this task back
3302 :     to the script. Otherwise problems arise in mixed environments such
3303 :     as Cygwin where scripts look and work like Unix scripts, but
3304 :     where OS.Process.system cannot run them.
3305 :    
3306 :     - In CM, the srcpath pickler used native pathname syntax -- which
3307 :     is incorrect in the case of cross-compilation. The new pickle format
3308 :     is independent of platform-specific naming conventions.
3309 :    
3310 :     - Path configuration files (such as lib/pathconfig) can now choose
3311 :     between native and standard syntax. Placing a line of the form
3312 :    
3313 :     standard!
3314 :    
3315 :     into the file causes all subsequent paths to be interpreted using
3316 :     CM standard pathname syntax (= Unix conventions); a line
3317 :    
3318 :     native!
3319 :    
3320 :     switches back to native style. This was needed so that
3321 :     path config files can be written portably, see src/system/pathconfig.
3322 :    
3323 :     - Runtime system:
3324 :    
3325 :     - win32-filesys.c: get_file_time and set_file_time now
3326 :     access modification time, not creation time.
3327 :    
3328 :     - I/O code made aware of new array representation.
3329 :    
3330 :     - Bug fixes in X86.prim.masm.
3331 :    
3332 :     - src/system/makeml made aware of win32. (For use under cygwin
3333 :     and other Unix-environments for windows.)
3334 :    
3335 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3336 :     which caused BinIO.inputAll to fail consistently.
3337 :    
3338 :     .bat scripts:
3339 :    
3340 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3341 :    
3342 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3343 :     applications (sml, ml-yacc, ml-lex).
3344 :     - ml-build.bat: analogous to ml-build.
3345 :     - config\install.bat: Analogous to config/install.sh. This requires
3346 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3347 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3348 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3349 :     and the bootfile hierarchy must have been unpacked under
3350 :     sml.boot.x86-win32.
3351 :     The script is very primitive and does a poor job at error checking.
3352 :     It only installs the base system, ml-lex, and ml-yacc. No other
3353 :     libraries are being installed (i.e., you get only those that
3354 :     are part of the compiler.)
3355 :     - link-sml.bat: analogous to .link-sml, but not currently used
3356 :    
3357 :     Unrelated bug fixes:
3358 :    
3359 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3360 :     types.
3361 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3362 :     otherwise.)

3386 :     Description:
3387 :    
3388 :     Two changes:
3389 :    
3390 :     1. Added a flag for controlling whether non-exhaustive bindings will
3391 :     be treated as errors (default is false).
3392 :     2. Cleaned up the *entire* source tree so that CMB.make goes through

3399 :     Description:
3400 :    
3401 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3402 :    
3403 :     This mainly affects the quality of error messages. However, some
3404 :     of the code is now more straightforward than before. (Treatment of
3405 :     the above four constructs in translate.sml is much simpler than
3406 :     the "macro-expansion" that was going on before. Plus, the mach-
3407 :     compiler no longer gets invoked just to be able to compile an
3408 :     if-expression.)
3409 :    
3410 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3411 :     interactive loop.

3417 :     Description:
3418 :    
3419 : blume 2155 Ported the runtime system to cygwin, which uses the unix
3420 : allenleung 1327 x86-unix bin files. Missing/buggy features:
3421 :    
3422 : blume 2155 o getnetbyname, getnetbyaddr: these functions seem to be missing in
3423 : allenleung 1327 the Cygwin library.
3424 :     o Ctrl-C handling may be flaky.
3425 :     o Windows system calls and Windows I/O are not supported.
3426 :    
3427 :     A new set of binfiles is located at:
3428 :    
3429 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3430 :    
3431 :     This is only needed for bootstrapping the cygwin version of smlnj.
3432 :     Other x86 versions can use the existing binfiles.

3457 :     Description:
3458 :    
3459 :     Fixed a serious bug in the rewrite code for FP spilling/reloading that
3460 :     sent the RA into an infinite loop when floating point registers get
3461 :     spilled. (Because of this bug, e.g., nucleic stopped compiling between
3462 :     110.37 and 110.38.)
3463 :     There was another set of potential problems related to the handling of
3464 :     MLRISC annotations (but those did not yet cause real problems, apparently).

3470 :     Description:
3471 :    
3472 :     Added a call of SrcPath.sync at the beginning of Parse.parse (in CM).
3473 :     This fixes the problem of CM getting confused by files that suddenly
3474 :     change their identity (e.g., by getting unlinked and recreated by some
3475 :     text editor such as vi). There might be a better/cheaper/cleaner way
3476 :     of doing this, but for now this will have to do.

3588 :     Another small change is that ppDec tries to give more information

3590 :     broken in some mysterious way if the functor's body's signature
3591 :     has not been declared by ascription but gets inferred from the

3691 :     Description:
3692 :    
3693 :     0. John Reppy made several modifications to the SML/NJ library.
3694 :     In particular, there is a shiny new controls-lib.cm.
3695 :    
3696 :     1. Pushed new controls interface through compiler so that everything
3697 :     compiles again.
3698 :    
3699 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3700 :     SML/NJ library (so that CML compiles again).
3701 :    
3702 :     3. Modified init scripts because XXX_DEFAULT environment variables
3703 :     are no longer with us. (Boot-time initialization is now done
3704 :     using the same environment variables that are also used for
3705 :     startup-time initialization of controls.)

3711 :     Description:
3712 :    
3713 :     All pseudo-ops emitted before the first segment declaration
3714 :     such as TEXT, DATA, and BSS directives are assumed to be global
3715 :     declarations and are emitted first in the assembly file. This is
3716 :     useful in a number of situations where one has pseudo-ops that are not
3717 :     specific to any segment, and also works around the constraint that one
3718 :     cannot have client pseudo-ops in the TEXT segment.
3719 :    
3720 :     Because no segment is associated with these declarations it is
3721 :     an error to allocate any space or objects before the first segment
3722 :     directive and an exception will be raised. However, we cannot make
3723 :     this check for client pseudo-ops.
3724 :    
3725 :     These top level declarations are a field in the CFG graph_info.
3726 :     In theory you can continue to add to this field after the CFG has been
3727 :     built -- provided you know what you are doing;-)

3737 :     - Stopgap measure for bug recently reported by Elsa Gunter (ppDec).

3750 :     Description:
3751 :    
3752 :     Applied the following bugfix provided by Emden Gansner:
3753 :    
3754 :     Output is corrupted when outputSubstr is used rather than output.
3755 :    
3756 : blume 2155 The problem occurs when a substring
3757 : blume 1189
3758 :     ss = (s, dataStart, dataLen)
3759 :    
3760 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3761 :     avail bytes of s, starting at index dataStart, are copied into the
3762 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3763 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3764 :     starting this copy at index dataStart+avail in s, the current code
3765 : blume 1189 starts the copy at index avail.
3766 :    
3767 :     Fix:
3768 :     In text-io-fn.sml, change line 695 from
3769 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3770 : blume 2155 to
3771 : blume 1189 val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

3787 :     Description:
3788 :    
3789 :     Added full support for div/mod/rem/quot on the x86, using the machine
3790 :     instruction's two results (without clumsily recomputing the remainder)
3791 :     directly where appropriate.
3792 :    
3793 :     Some more extensive power-of-two support was added to the x86 instruction
3794 :     selector (avoiding expensive divs, mods, and muls where they can be
3795 :     replaced with cheaper shifts and masks). However, this sort of thing
3796 :     ought to be done earlier, e.g., within the CPS optimizer so that
3797 :     all architectures benefit from it.
3798 :    
3799 :     The compiler compiles to a fixed point, but changes might be somewhat
3800 :     fragile nevertheless. Please, report any strange things that you might
3801 :     see wrt. div/mod/quot/rem...

3808 :    
3809 :     Fixed my broken div/mod logic. Unfortunately, this means that the

3811 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3812 :     The problem was with quotient = 0, because that alone does not tell
3813 :     us which way the rounding went. One then has to look at whether
3814 :     remainder and divisor have the same sign... :(

3822 :     Description:
3823 :    
3824 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
3825 :    
3826 :     Primops have changed. This means that the bin/boot-file formats have
3827 :     changed as well.
3828 :    
3829 :     To make sure that there is no confusion, I made a new version.
3830 :    
3831 :    
3832 :     CHANGES:
3833 :    
3834 :     * removed REMT from mltree (remainder should never overflow).
3835 :    
3836 :     * added primops to deal with divisions of all flavors to the frontend
3837 :    
3838 :     * handled these primops all the way through so they map to their respective
3839 :     MLRISC support
3840 :    
3841 :     * used these primops in the implementation of Int, Int32, Word, Word32
3842 :    
3843 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3844 :    
3845 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
3846 :    
3847 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3848 :     floating point
3849 :    
3850 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3851 :     and Real (but Real.abs maps to a separate floating-point-only primop)
3852 :    
3853 :    
3854 :     TODO items:
3855 :    
3856 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
3857 :     instructions because the machine instruction encoder cannot handle
3858 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
3859 :     REM in the first place, and REM is supported by the x86 machine coder.)
3860 :    
3861 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
3862 :     selection phase. (The two can be streamlined because the hardware
3863 :     delivers both quotient and remainder at the same time anyway.)
3864 :    
3865 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
3866 :     (Currently the behavior is inconsistent both across architectures and
3867 :     wrt. the draft Basis spec.)
3868 :    
3869 :     * Word8 should eventually be handled natively, too.
3870 :    
3871 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
3872 :     as if there currently is no execution path that could trigger it in
3873 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
3874 :     hold for things like multiplication and division.)

3879 :     Tag: blume-20020327-mlrisc-divisions
3880 :     Description:
3881 :    
3882 :     Added support for all four division operations (ML's div, mod, quot,
3883 :     and rem) to MLRISC. In the course of doing so, I also rationalized
3884 :     the naming (no more annoying switch-around of DIV and QUOT), by
3885 :     parameterizing the operation by div_rounding_mode (which can be either
3886 :     DIV_TO_ZERO or DIV_TO_NEGINF).
3887 :    
3888 :     The generic MLTreeGen functor takes care of compiling all four
3889 :     operations down to only round-to-zero div.
3890 :    
3891 :     Missing pieces:
3892 :    
3893 :     * Doing something smarter than relying on MLTreeGen on architectures
3894 :     like, e.g., the x86 where hardware division delivers both quotient and
3895 :     remainder at the same time. With this, the implementation of the
3896 :     round-to-neginf operations could be further streamlined.
3897 :    
3898 :     * Remove inlining support for div/mod/rem from the frontend and replace it
3899 :     with primops that get carried through to the backend. Do this for all
3900 :     int and word types.

3905 :     Tag: blume-20020325-divmod
3906 :     Description:
3907 :    
3908 :     I improved (hopefully without breaking them) the implementation of Int.div,
3909 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
3910 :     advantage of the following observations:
3911 :    
3912 :     Let q = x quot y r = x rem y
3913 :     d = x div y m = x mod y
3914 :    
3915 :     where "quot" is the round-to-zero version of integer division that
3916 :     hardware usually provides. Then we have:
3917 :    
3918 :     r = x - q * y where neither the * nor the - will overflow
3919 :     d = if q >= 0 orelse x = q * y then q else q - 1
3920 :     where neither the * nor the - will overflow
3921 :     m = if q >= 0 orelse r = 0 then r else r + y
3922 :     where the + will not overflow
3923 :    
3924 :     This results in substantial simplification of the generated code.
3925 :     The following table shows the number of CFG nodes and edges generated
3926 :     for
3927 :     fun f (x, y) = x OPER y
3928 :     (* with OPER \in div, mod, quot, rem *)

3970 :    
3971 :     1. Changes to FLINT primops:
3972 :    
3973 :     (* make a call to a C-function;
3974 :     * The primop carries C function prototype information and specifies
3975 :     * which of its (ML-) arguments are floating point. C prototype
3976 :     * information is for use by the backend, ML information is for
3977 :     * use by the CPS converter. *)
3978 :     | RAW_CCALL of { c_proto: CTypes.c_proto,
3979 :     ml_args: ccall_type list,
3980 :     ml_res_opt: ccall_type option,
3981 :     reentrant : bool
3982 :     } option
3983 :     (* Allocate uninitialized storage on the heap.
3984 :     * The record is meant to hold short-lived C objects, i.e., they
3985 : blume 2155 * are not ML pointers. With the tag, the representation is
3986 : leunga 1174 * the same as RECORD with tag tag_raw32 (sz=4), or tag_fblock (sz=8)
3987 :     *)
3988 : blume 2155 | RAW_RECORD of {tag:bool,sz:int}
3989 : leunga 1174 and ccall_type = CCALL_INT32 | CCALL_REAL64 | CCALL_ML_PTR
3990 :    
3991 :     2. These CPS primops are now overloaded:
3992 :    
3993 :     rawload of {kind:numkind}
3994 :     rawstore of {kind:numkind}
3995 :    
3996 :     The one argument form is:
3997 :    
3998 :     rawload {kind} address
3999 :    
4000 :     The two argument form is:
4001 : blume 2155
4002 : leunga 1174 rawload {kind} [ml object, byte-offset]
4003 :    
4004 :     3. RAW_CCALL/RCC now takes two extra arguments:
4005 :    
4006 :     a. The first is whether the C call is reentrant, i.e., whether
4007 :     ML state should be saved and restored.
4008 :     b. The second argument is a string argument specifying the name of
4009 :     library and the C function.
4010 :    
4011 :     These things are currently not handled in the code generator, yet.
4012 :    
4013 :     4. In CProto,
4014 :    
4015 : blume 2155 An encoding type of "bool" means "ml object" and is mapped into
4016 :     C prototype of PTR. Note that "bool" is different than "string",
4017 : leunga 1174 even though "string" is also mapped into PTR, because "bool"
4018 :     is assigned an CPS type of BOGt, while "string" is assigned INT32t.
4019 :    
4020 :     5. Pickler/unpicker
4021 :    
4022 :     Changed to handle RAW_RECORD and newest RAW_CCALL
4023 :    
4024 :     6. MLRiscGen,
4025 :    
4026 :     1. Changed to handle the new rawload/rawstore/rawrecord operators.
4027 :     2. Code for handling C Calls has been moved to a new module CPSCCalls,
4028 :     in the file CodeGen/cpscompile/cps-c-calls.sml
4029 :    
4030 :     7. Added the conditional move operator
4031 :    
4032 :     condmove of branch
4033 :    
4034 : blume 2155 to cps. Generation of this is still buggy so it is currently

4042 :    
4043 : blume 2155 Implemented the Ball-Larus branch prediction-heuristics, and
4044 : george 1168 incorporated graphical viewers for control flow graphs.
4045 :    
4046 : george 1171 Ball-Larus Heuristics:
4047 : george 1168 ---------------------
4048 :     See the file compiler/CodeGen/cpscompile/cpsBranchProb.sml.
4049 :    
4050 :     By design it uses the Dempster-Shafer theory for combining
4051 :     probabilities. For example, in the function:
4052 :    
4053 :     fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)
4054 :    
4055 :     the ball-larus heuristics predicts that the n=0 is unlikely
4056 :     (OH-heuristic), and the 'then' branch is unlikely because of the
4057 :     RH-heuristic -- giving the 'then' branch an even lower combined
4058 : george 1171 probability using the Dempster-Shafer theory.
4059 : george 1168
4060 :     Finally, John Reppy's loop analysis in MLRISC, further lowers the
4061 :     probability of the 'then' branch because of the loop in the else
4062 :     branch.
4063 :    
4064 :    
4065 :     Graphical Viewing:
4066 : blume 2155 ------------------
4067 : george 1168 I merely plugged in Allen's graphical viewers into the compiler. The
4068 :     additional code is not much. At the top level, saying:
4069 :    
4070 :     Control.MLRISC.getFlag "cfg-graphical-view" := true;
4071 :    
4072 :     will display the graphical view of the control flow graph just before
4073 :     back-patching. daVinci must be in your path for this to work. If
4074 :     daVinci is not available, then the default viewer can be changed
4075 :     using:
4076 :    
4077 :     Control.MLRISC.getString "viewer"
4078 :    
4079 :     which can be set to "dot" or "vcg" for the corresponding viewers. Of
4080 :     course, these viewers must be in your path.
4081 :    
4082 :     The above will display the compilation unit at the level of clusters,
4083 :     many of which are small, boring, and un-interesting. Also setting:
4084 :    
4085 :     Control.MLRISC.getInt "cfg-graphical-view_size"
4086 :    
4087 :     will display clusters that are larger than the value set by the above.

4097 :     a minor bug in one place where it was used.

4111 :     Description:
4112 :    
4113 : blume 2155 1. Recoded the buggy parts of x86-fp.
4114 : leunga 1156
4115 :     a. All the block reordering code has been removed.
4116 :     We now depend on the block placement phases to do this work.
4117 :    
4118 :     b. Critical edge splitting code has been simplified and moved into the
4119 :     CFG modules, as where they belong.
4120 :    
4121 :     Both of these were quite buggy and complex. The code is now much, much
4122 :     simpler.
4123 :    
4124 :     2. X86 backend.
4125 :    
4126 :     a. Added instructions for 64-bit support. Instruction selection for
4127 :     64-bit has not been committed, however, since that
4128 : blume 2155 requires changes to MLTREE which haven't been approved by
4129 : leunga 1156 Lal and John.
4130 :    
4131 : blume 2155 b. Added support for FUCOMI and FUCOMIP when generating code for
4132 : leunga 1156 PentiumPro and above. We only generate these instructions in
4133 :     the fast-fp mode.
4134 :    
4135 : blume 2155 c. Added cases for JP and JNP in X86FreqProps.
4136 :    
4137 : leunga 1156 3. CFG
4138 :    
4139 :     CFG now has a bunch of methods for edge splitting and merging.
4140 :    
4141 :     4. Machine description.
4142 :    
4143 :     John's simplification of MLTREE_BASIS.fcond broke a few machine
4144 :     description things:
4145 :    
4146 :     rtl-build.{sig,sml} and hppa.mdl fixed.
4147 :    
4148 : blume 2155 NOTE: the machine description stuff in the repository is still broken.
4149 :     Again, I can't put my fixes in because that involves
4150 :     changes to MLTREE.

4155 :     Tag: blume-20020320-kmp
4156 :     Description:
4157 :    
4158 :     Implemented Knuth-Morris-Pratt string matching in PreString and used
4159 :     it for String.isSubstring, Substring.isSubstring, and
4160 :     Substring.position.
4161 :    
4162 :     (Might need some stress-testing. Simple examples worked fine.)

4167 :     Tag: blume-20020319-witnesses
4168 :     Description:
4169 :    
4170 :     Added a structure C.W and functions convert/Ptr.convert to ml-nlffi-lib.
4171 :    
4172 :     This implements a generic mechanism for changing constness qualifiers
4173 :     anywhere within big C types without resorting to outright "casts".
4174 :     (So far, functions such as C.rw/C.ro or C.Ptr.rw/C.Ptr.ro only let you
4175 :     modify the constness at the outermost level.)
4176 :     The implementation of "convert" is based on the idea of "witness"
4177 :     values -- values that are not used by the operation but whose types
4178 :     "testify" to their applicability. On the implementation side, "convert"
4179 :     is simply a projection (returning its second curried argument). With
4180 :     cross-module inlining, it should not result in any machine code being
4181 :     generated.

4187 :     Description:
4188 :

4192 :    
4193 :     and
