151 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
152 : blume 2692 Date: 2007/06/06 21:45:00 CDT
153 :     Description:
154 :    
155 :     - Aaron: fixed a number of bugs in ml-ulex.
156 :     - Matthias:
157 :     - added CM control "cm.force-tools"; this is false by default;
158 :     when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
159 :     will be forced to run regardless of whether or not their targets
160 :     are up-to-date
161 :     - changed installer code so that config/install.sh will re-build
162 :     heap images for all tools even if those heap images already existed
163 :    
164 :     ----------------------------------------------------------------------
165 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
166 : blume 2688 Date: 2007/06/04 21:21:00 CDT
167 :     Description:
168 :    
169 :     After Aaron Turon's bug fix for ml-ulex (handling the ^ character
170 :     in legacy mode), re-ran the lexer generator on all lex input files
171 :     and committed the results.
172 :    
173 :     This should fix the problem with ckit and nlffi that was reported
174 :     by Vesa A. Norrman.

185 : dbm 2650 Name: Dave MacQueen (dbm@cs.uchicago.edu)
186 :     Date: 2007/05/31 14:55:00 CDT
187 :     Revision: 2650
188 :     Description:
189 :    
190 :     3rd merge of base from primop-branch-3 into the trunk.
191 :     Additional bug fixes included:
192 :    
193 :     * Timer.cpu_timer, etc. type printing corrected (by making
194 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
195 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
196 :     Stefan Monnier)
197 :    
198 :     ----------------------------------------------------------------------
199 : blume 2645 Name: Matthias Blume (http://www.tti-c.org/blume/)
200 :     Date: 2007/05/31 11:40:00 CDT
201 :     Description:
202 :    
203 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
204 :    
205 :     Also, changed the handling of "no core access": When translate.sml
206 :     needs access to a core exception at a time when the core has not
207 :     been set up yet (this only happens when compiling system/smlnj/init/*),
208 :     then don't bother generating the corresponding tests.
209 :    
210 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
211 :     the exception. Unfortunately, that confuses the plambda type checker.
212 :     Moreover, it does not do any good, because at runtime we don't expect
213 :     such an exception to be ever raised. (The code in system/smlnj/init/*
214 :     has to be written very carefully with this in mind!)

217 : mrainey 2639 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
218 :     Date: 2007/05/29
219 :     Description:
220 :    
221 :     Added FSQRT instructions for the AMD64 code generator.
222 :    
223 :     ----------------------------------------------------------------------
224 : blume 2626 Name: Matthias Blume (http://www.tti-c.org/blume/)
225 :     Date: 2007/05/29 19:00:00 CDT
226 :     Description:
227 :    
228 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
229 :     with an explicit test for zero division. This should fixes several
230 :     regressions and makes it possible for downstream optimization phases
231 :     to treat these operations as "pure" when they are applied to unsigned
232 :     operands.
233 :

235 : mrainey 2622 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
236 :     Date: 2007/05/29
237 :     Description:
238 :    
239 :     Added the new MLRISC code generator for the AMD64. This version,
240 :     in contrast to the previous one, uses SSE registers and instructions
241 :     for all floating-point computations.
242 :

244 : jhr 2613 Name: John Reppy (http://www.cs.uchicago.edu/~jhr)
245 : jhr 2617 Date: 2007/05/29
246 : jhr 2613 Description:
247 :    
248 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
249 :     for bugs #1415 and #1416. We also now correctly handle format characters that
250 :     lie outside the specified set.

253 : blume 2610 Name: Matthias Blume (http://www.tti-c.org/blume/)
254 :     Date: 2007/05/23 22:30:00 CDT
255 :     Description:
256 :    
257 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
258 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
259 :    
260 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
261 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
262 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
263 :     while running CMB.make. The point is that the single symbol
264 :     NO_PLUGINS is definde in all three cases.)
265 :    
266 :     I changed the three locations within the sources that get compiled
267 :     during CMB.make where ml-yacc or ml-lex input is processed: When
268 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
269 :     is bypassed.
270 :    
271 :     When bootstrapping new versions of the compiler, there can be
272 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
273 :     are not available or otherwise not operational. In this case one can
274 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
275 :     do so, the following command should be issued at the interactive
276 :     prompt:
277 :    
278 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
279 :    
280 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
281 :     files that normally would be generated by ml-yacc and ml-lex.
282 :     (Copies of these files are in the repository.)

285 : dbm 2603 Name: David MacQueen (dbm@cs.uchicago.edu)
286 :     Date: 2007/5/23 17:23:00 CDT
287 :     Revision: 2603
288 :     Description:
289 :    
290 :     2nd merge of base from primop-branch-3 into the trunk.
291 :     Additional bug fixes included:
292 :     Date.scan and Date.fromString fixed;
293 :     Overloading resolution fixed and some type printing problems corrected.

296 : blume 2578 Name: Matthias Blume (http://www.tti-c.org/blume/)
297 : blume 2589 Date: 2007/05/23 09:50:00 CDT
298 :     Description:
299 :    
300 :     Changed the installation mechanism for CM tool plugins. These are
301 :     just libaries and now get installed like ordinary libaries.
302 :    
303 :     There are now a number of new installation targets that give some
304 :     fine-grain control over what classes and suffixes are known, and what
305 :     they will map to.
306 :     See config/targets for details.
307 :    
308 :     The code that caused plugin installation as part of running a
309 :     tool's "build" script has been removed. (The build script is for
310 :     building, not for installing.)
311 :    
312 :     ----------------------------------------------------------------------
313 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
314 : blume 2578 Date: 2007/05/22 11:50:00 CDT
315 :     Description:
316 :    
317 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
318 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
319 :     CM fail if a shell tool reports a non-success exit status. If
320 :     the control is set to true, then CM will press on after tool failures
321 :     in the event that the target files exist (even though they are
322 :     considered outdated). Turning the control to true can be useful for
323 :     bootstrapping.

326 : adrassi 2570 Name: Aaron Turon (http://www.cs.uchicago.edu/~adrassi)
327 :     Date: 2007/05/19
328 :     Description:
329 :    
330 :     Merge of ml-lpt revisions for 110.64.
331 :    
332 :     The name of several ml-lpt-lib modules has changed:
333 :     Repair => AntlrRepair
334 :     StreamPos => AntlrStreamPos
335 :     ErrHandlerFn => AntlrErrHandler
336 :     EBNF => AntlrEBNF
337 :    
338 :     The ml-antlr specification format has changed: declarations such as
339 :     %tokens and nonterminal definitions can occur *multiple* times in the
340 :     same specification. The semantics are such that each new declaration
341 :     extends the previous ones. This does not apply to %start or %name,
342 :     of course.
343 :    
344 :     Importing a grammar via %import now includes *all* declarations in from
345 :     the imported grammar, except for %name, %entry, and %start. Tokens
346 :     and nonterminals can be dropped using the new %dropping clause of the
347 :     %import directive; the separate %drop and %extend have been removed.
348 :    
349 :     We now allow optional type annotations on nonterminals, using the %nonterms
350 :     directive as in ml-yacc.
351 :    
352 :     The refcell construct is now implemented using SML's regular reference
353 :     cells, so the :== and !! notation has been deprecated.
354 :    
355 :     The ml-antlr tool now does much more checking of specifications, and
356 :     its error messages have been greatly improved. Error repair for
357 :     generated parsers has been completely rewritten, and is now both
358 :     much faster and more accurate.
359 :    
360 :     ml-ulex is now more lenient with escape codes (non-SML-standard
361 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
362 :     Also, character classes may now include a "-" character at the beginning
363 :     as is standard in most other regexp tools.
364 :    
365 :     All of these changes are documented in the user guide, which has
366 :     been updated and improved with this merge.

372 :     Description:
373 :    
374 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
375 :     Significant changes in FLINT and the front end, mostly having to do
376 :     with a reorganized system for handling primops. Various bug fixes
377 :     and improvements in printing signatures.

383 :    
384 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
385 :     The ml-antlr specification format has changed: declarations such as
386 :     %tokens and nonterminal definitions can occur *multiple* times in the
387 :     same specification. The semantics are such that each new declaration
388 :     extends the previous ones. Grammar extension constructs have also
389 :     changed. We now allow type annotations on nonterminals. Finally,
390 :     the refcell construct is now implemented using SML's regular reference

392 :     changes will appear in the 110.64 user guide for ml-lpt.
393 :    
394 :     The ml-antlr tool now does much more checking of specifications, and
395 :     its error messages have been greatly improved. There has also been
396 :     some work on the error repair process for generated parsers, but this

433 :     Description:
434 :    
435 :     More Basis fixes: The Char.fromString (etc.) functions did not handle
436 :     the "\uxxxx" escape sequence. There is still an outstanding bug with
437 :     String.fromString the tail is a format escape. I added a comment to
438 :     this effect in Basis/Implementation/string.sml.

517 :     Description:
518 :    
519 :     Added preliminary support in MLRISC for Staged Allocation, a technique
520 :     for specifying calling conventions (see
521 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
522 :     Initially, we plan to use this code to generate C calls for the AMD64.
523 :    
524 :     The staged allocation code base resides in MLRISC/staged-allocation,
525 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

531 :    
532 :     Bug fix: when SaveCState was called with two values to save, a subsequent

545 :    
546 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
547 :     of the range -128 ... 127. I've changed the code so that the range
548 :     check is disabled. Only the low order 8 bits of the immediate operand

557 :     Eliminated any mention of lexgen. (Lexgen was an early precursor

589 :     Date: 2007/01/31
590 :     Description:
591 :    
592 :     Brought ml-lpt manual up-to-date with the code. Many minor
593 :     improvements to the tools, and a few minor bugfixes. Prepared
594 :     ml-lpt-lib for integration with new UTF8 structure. Changed
595 :     the interface for creating streams in ml-ulex (we now support
596 :     stream creation from several kinds of sources). Overall, the
597 :     tools are now quite stable, and their interfaces are unlikely to
598 :     change in a way that would break compatibility. More work,
599 :     however, is needed in the documentation.

604 :     Description:
605 :    
606 :     Implemented library installer. Moved CM plugin code for
607 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
608 :     their respective trees. Implemented CM plugin for ml-ulex
609 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
610 :     and ml-antlr.
611 :    
612 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
613 :     CM tools. (It turns out to be too messy to do otherwise because
614 :     there is too much code that during installation relies on the presence
615 :     of these tools -- resulting in a tricky ordering problem.)

620 :     Description:
621 :    
622 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
623 :     Modified CM's startup code to use shiftArgs as it processes
624 :     command line arguments. This way, the init code in each .sml-file
625 :     or library that is mentioned at the top level will see only
626 :     those arguments that have not yet been processed at this point.
627 :     In other words, the init code can "seize control" and process the
628 :     remaining command line.

685 :    
686 :     Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to

694 :     Date: 2006/12/08 09:50:00 CST
695 :     Description:
696 :    
697 :     Added code to CM's "standard shell tool" implementation which
698 :     causes it to tolerate (with a warning) the situation where the shell
699 :     command fails (e.g., due to the shell command's non-existence)
700 :     as long as all target files exist.
701 :    
702 :     This makes it possible to, e.g., build ml-yacc from sources even if
703 :     svn checkout messed up the time stamps on files in such a way that
704 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
705 :     be needed to re-process yacc.grm, but obviously it might not yet be
706 :     available at that time.)

712 :    
713 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
714 :     recvVecFromNB' in the SOCKET signature. This error is actually
715 :     in the SML Basis specification too.

729 :    
730 :     Use Say.vsay for printing the "[autoloading]" message, so

745 :     Tag: release-110.60
746 :     Description:
747 :    
748 :     New working release (110.60). NEW BOOTFILES!
749 :    
750 :     This is the first subversion-hosted release. There are also changes
751 :     to the directory layout. Here is a table:
752 :    
753 :     (All pathnames are relative to the SML/NJ "root" directory.)
754 :    
755 :     config -> config
756 :    
757 :     src/cm -> base/cm
758 :     src/compiler -> base/compiler
759 :     src/runtime -> base/runtime
760 :     src/system -> base/system
761 :    
762 :     src/cm/pgraph -> pgraph
763 :    
764 :     src/READMES -> base/READMES
765 :     src/$notefile -> base/NOTES/$notefile
766 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
767 :     MACOSXINSTALL WININSTALL
768 :    
769 :     src/smlnj-lib -> smlnj-lib
770 :     src/MLRISC -> MLRISC
771 :     ckit -> ckit
772 :     src/cml -> cml
773 :     src/eXene -> eXene
774 :     src/heap2asm -> heap2asm
775 :     src/lexgen -> lexgen
776 :     src/ml-burg -> ml-burg
777 :     src/ml-lex -> ml-lex
778 :     src/ml-yacc -> ml-yacc
779 :     src/ml-nlffi-lib -> nlffi/lib
780 :     src/ml-nlffigen -> nlffi/gen
781 :     src/smlnj-c -> smlnj-c
782 :     src/tools/TraceDebugProf -> trace-debug-profile
783 :    
784 :     In addition, there is also a new
785 :    
786 :     ml-lpt
787 :    
788 :     directory containing two new program generator tools: ml-ulex and
789 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
790 :     LL(k) parser generator). These tools are currently "beta-quality"
791 :    
792 :     The latest versios of the sources can now be obtained anonymously
793 :     via subversion. For this, it is useful to first check out
794 :    
795 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
796 :    
797 :     and put the resulting directory on your shell's PATH. This provides
798 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
799 :     and refresh-all.sh.
800 :    
801 :     To create a freshly checked-out copy of the sources, do
802 :    
803 :     checkout-all.sh [dir]
804 :    
805 :     where dir is the optional SML/NJ root directory (default is ".").
806 :    
807 :     This creates the above directory layout. Each subdirectory of
808 :     the root is under individual subversion control. The stat-all.sh
809 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
810 :     each of these subtrees.
811 :

814 : blume 2155 Date: 2006/11/02 12:20:00 CST
815 :     Description:
816 :    
817 :     Reorganized directory layout.
818 :    
819 :     This is a temporary solution, more reorganization is to come.
820 :    
821 :     The basic idea is to have a number of toplevel trees, each corresponding
822 :     to a well-defined part of the overall system. Each part can be
823 :     maintained individually, even in separate source repositories,
824 :     although currently we still serve everything out of the main
825 :     smlnj-gforge tree.
826 :    
827 :     Installer and and scripts have been updated to reflect the new
828 :     layout. The installer (base/src/system/smlnj/installer) is now
829 :     "scriptable" to avoid burning too much knowledge about the
830 :     layout into SML source code. The main script used by the installer
831 :     is in config/actions.
832 :    
833 :     The main change is that many of the subdirectories of what used to
834 :     be known as "src" have moved to the toplevel. The "src" directory
835 :     itself has moved down into a subtree called "base". (We may eventually
836 :     get rid of the extra level of indirection represented by "src".)
837 :    
838 :     The layout is now as follows:
839 :    
840 :     toplevel tree name | default repository
841 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
842 :     -------------------+----------------------------------------------------
843 :     config | $gf/config/trunk
844 :     |
845 :     base | $gf/sml/trunk
846 :     |
847 :     smlnj-lib | $gf/smlnj-lib/trunk
848 :     MLRISC | $gf/MLRISC/trunk
849 :     |
850 :     ml-yacc | $gf/ml-yacc/trunk
851 :     ml-lex | $gf/ml-lex/trunk
852 :     ml-burg | $gf/ml-burg/trunk
853 :     lexgen | $gf/lexgen/trunk
854 :     heap2asm | $gf/heap2asm/trunk
855 :     |
856 :     cml | $gf/cml/trunk
857 :     eXene | $gf/eXene/trunk
858 :     ckit | $gf/ckit/trunk
859 :     nlffi | $gf/nlffi/trunk
860 :     |
861 :     smlnj-c | $gf/smlnj-c/trunk
862 :    
863 :     In $gf/admin there are a few useful shell scripts for checking out
864 :     and maintaining the entire collection of trees:
865 :    
866 :     admin/checkout-all.sh [dir]
867 :     -- optionally creates dir and checks out all trees from their
868 :     default repositories; if dir is missing, checkout into .

1021 :     Description:
1022 :    
1023 :     Hooked code for Darwin-specific Intel ABI into main compiler.
1024 :     (This is a temporary solution which relies on the fact that the
1025 :     compiler itself does not use NLFFI. Eventually we need to divorce
1026 :     intel mac from generic x86 unix code and make separate sets of binaries.)

1055 :     Description:
1056 :    
1057 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1058 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1059 : blume 2155 at the time when config/preloads is processed, the library has to
1060 : mblume 1878 be referred to by another name. In 110.57 this would be
1061 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1062 :     to be valid as well.)

1117 :     Tag: blume-22051115-versiontool
1118 :     Description:
1119 :    
1120 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1121 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1122 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1123 :     it. Instead, it has the status of "user code", so it should use
1124 :     $/basis.cm to refer to the Basis library. (At least that's true for
1125 :     the purpose of bootstrapping the previous change. In the future it
1126 :     might make sense to have versiontool.cm refer to
1127 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1128 :     compiler itself uses.)
1129 :    
1130 :     Also patched src/system/testml to have it activate those extra anchor
1131 :     bindings in config/extrapathconfig.

1136 :     Tag: blume-22051115-libraries
1137 :     Description:
1138 :    
1139 :     This change affects the way the following libraries are tied into
1140 :     the system:
1141 :    
1142 :     $/basis.cm
1143 :     $/smlnj-lib.cm
1144 :     $/pp-lib.cm
1145 :     $/controls-lib.cm
1146 :     $/html-lib.cm
1147 :     $/ml-yacc-lib.cm
1148 :    
1149 :     These libraries are now internally (as seen from the source code
1150 :     of the implementation itself) known by the following names:
1151 :    
1152 :     $smlnj/basis/basis.cm
1153 :     $smlnj/smlnj-lib/smlnj-lib.cm
1154 :     $smlnj/smlnj-lib/pp-lib.cm
1155 :     $smlnj/smlnj-lib/controls-lib.cm
1156 :     $smlnj/smlnj-lib/html-lib.cm
1157 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1158 :    
1159 :     This makes it possible to work with code that requires different
1160 :     versions of these libraries, and which refers to these libraries using
1161 :     their "default" names (i.e., the first set of names above). In other
1162 :     words, one can un-define or re-define those default names without
1163 :     compromising the proper functioning of the compiler itself.
1164 :    
1165 :     A similar procedure had already been performed for several of the
1166 :     MLRISC libraries that are linked into the compiler. I did some
1167 :     cleanup on this code.
1168 :    
1169 :     A new file in the config directory (named extrapathconfig) is
1170 :     responsible for setting up path anchors that the compiler itself does
1171 :     not need, but that are typically required by user code.

1350 :     Tag: blume-20050516-redump-heap
1351 :     Description:
1352 :    
1353 :     Added mechanism for re-creating a heap file for the interactive system
1354 :     after configuration variables have been changed.
1355 :    
1356 :     CM.redump_heap : string -> unit
1357 :    
1358 :     This is much like SMLofNJ.exportML, but starting from the resulting
1359 : blume 2155 heap does not return to the caller of CM.redump_heap but
1360 : mblume 1792 restarts the interactive system from scratch. The original call of
1361 :     CM.redump_heap does not return but ends the interactive session.
1362 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1363 :    
1364 :     Internally, redump_heap winds the dynamic execution context back to
1365 :     the point where the original heap image was created and re-executes
1366 :     the heap image generation code in the boot code.

1482 :     Tag: blume-20050114-heap2exec
1483 :     Description:
1484 :    
1485 :     Implemented new (but still experimental) heap2exec facility. This is
1486 :     tested under Mac OS X and should work under Linux (will test shortly).
1487 :     It will probably also work on the Sparc (will test some time later).
1488 :    
1489 :     - removed old "HACKED_STANDALONE" hack from runtime
1490 :    
1491 :     To be able to test this, uncomment the request for "heap2asm" in
1492 :     config/targets prior to installation. (Notice that this is different
1493 :     from "heap2exec" mentioned below. Not a typo.)
1494 :    
1495 :     To perform an actual test, run the command
1496 :    
1497 :     $ bin/heap2exec heapfile execfile
1498 :    
1499 :     (You can put heap2exec on your shell's path.)
1500 :    
1501 :     For example, run
1502 :    
1503 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1504 :    
1505 :     This will create a standalone executable called "mly" which you can
1506 :     then invoke directly as a command.

1531 :     (The parameter-passing part of the picture has not complete. But
1532 :     data structure access seems to work.)
1533 :    
1534 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1535 :     (On the Mac, it is big-endian. And that's currently our only
1536 :     PPC platform.)

1553 :    
1554 : blume 2155 The Unix I/O library of SML/NJ on cygwin does not understand

1651 :     Tag: blume-20041124-position
1652 :     Description:
1653 :    
1654 :     The compiler can now be compiled in a mode that makes structure Position
1655 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1656 :     for the time being.
1657 :    
1658 :     To enable 64-bit positions, use the following procedure:
1659 :    
1660 :     1. Start sml
1661 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1662 :     3. Type
1663 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1664 :     4. Run CMB.make() as usual.
1665 :    
1666 :     This is barely tested. The only test so far was a little SML program
1667 :     counting the number of characters in an 8-gigabyte file by
1668 :     reading it character-by-character. That test was successful.
1669 :    
1670 :     In support of 64-bit positions, a number of new functions have been
1671 :     added to the runtime system.

1712 :     Description:
1713 :    
1714 :     - Stripped down the versiontool: It now only handles the version number.
1715 :     The date string is generated at bootstrap time (during makeml).
1716 :    
1717 :     - In a previous commit, fixed a minor issue with how polyequal is being
1718 :     translated. In particular, the code now "looks through" abstractions.
1719 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1720 :     more efficient code. Important examples for where this matters are
1721 :     the new int64 and word64 types.

1737 :    
1738 :     All the pieces of Word64 are now there, with the exception of the
1739 :     conversions from and to LargeWord. (Eventually these need to be identities,
1740 :     but for the time being they don't even make sense because LargeWord is
1741 :     32-bit wide.)
1742 :    
1743 :     Also started to add similar support for Int64, but major pieces of that
1744 :     are still missing.

1750 :     Description:
1751 :    
1752 :     Structure Word64 is now (almost) complete, word literals and patterns
1753 :     seem to work. There are a few odd pieces missing. In particular,
1754 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1755 :     at the moment.
1756 :    
1757 :     Making Word64 official would mean that LargeWord becomes Word64. But
1758 :     this requires extreme care because most word-word conversions have to
1759 :     go through LargeWord, so making a mistake means loss of efficiency or
1760 :     worse. Eventually there will be a solution similar to (but actually
1761 :     simpler than) what I did with IntInf.

1798 :     normally does not have to be edited to reflect a version change.
1799 :    
1800 :     (As a result, a version change can be done by just editing
1801 :     config/version, the rest is now automatic.)

1841 :     Tag: blume-20041020-standalone-backtrace
1842 :     Description:
1843 :    
1844 :     Added a mechanism for getting back-trace information from standalone
1845 :     programs. Here is how it works:
1846 :    
1847 :     1. The part of the program from which you want to get backtrace
1848 :     information (usually the whole program) should be wrapped with
1849 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
1850 :     main program could be modified from something like
1851 :    
1852 :     fun main (pgm, args) = ...
1853 :    
1854 :     to
1855 :    
1856 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1857 :    
1858 :     2. To be able to access BackTrace.monitor, you have to add
1859 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
1860 :     main function.
1861 :    
1862 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1863 :     CM might have created in the past for your project).
1864 :    
1865 :     4. Build the system using this command line:
1866 :    
1867 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1868 :     myprog.cm MyProg.main myprog
1869 :    
1870 :     instead of the usual
1871 :    
1872 :     ml-build myprog.cm MyProg.main myprog
1873 :    
1874 :     I changed a library name:
1875 :    
1876 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1877 :    
1878 :     New libraries:
1879 :    
1880 :     $smlnj-tdp/back-trace.cm
1881 :     -- when loaded causes the back-trace plugin to be installed
1882 :     $smlnj-tdp/coverage.cm
1883 :     -- when loaded causes the coverage plugin to be installed

1899 :     Description:
1900 :    
1901 :     * Test coverage tool added!
1902 :     * Further reorganization of tracing-, debugging-, and profiling support:
1903 :    
1904 :     - moved original BTImp -- now called BackTrace -- into a separate
1905 :     library called $/trace-debug-profile.cm
1906 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
1907 :     - only the instrumentation mechanism is now left in the compiler proper
1908 :     - BackTrace module is a plugin which is NOT plugged in by default
1909 :     - Coverage module is another such plugin
1910 :    
1911 :     To get the benefits of any of these plugin modules, the code in
1912 :     question must be compiled with tdp instrumentation turned on. This
1913 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
1914 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1915 :    
1916 :     Plugins are selected at link time. (Pre-compiled instrumented code
1917 :     can be re-loaded with different plugins in effect.) When an
1918 :     instrumented module is linked, whatever plugins are at that time
1919 :     enabled will come into effect for that module.
1920 :    
1921 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
1922 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
1923 :     To enable the coverage plugin, load the same library and invoke
1924 :     Coverage.install().
1925 :    
1926 :     Back-traces are generated automatically on uncaught exceptions and
1927 :     when the code in question explicitly invokes BackTrace.trigger().
1928 :    
1929 :     Coverage (and execution frequency-) information must be queried
1930 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

1955 :    
1956 :     The control flag controlling whether instrumentation is on or off is now

2048 :     Description:
2049 :    
2050 :     Implemented some CM magic to have
2051 :     file src/compiler/TopLevel/main/version.sml
2052 :     generated automagically.
2053 :     The version is taken from two files: config/version and config/release.
2054 :     The first is expected to contain a two-part version number such as 110.49.
2055 :     The second should contain a single number, but it may be missing.
2056 :    
2057 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2058 :     time the version tool is loaded (which is the first time you say CMB.make),
2059 :     then the tool will increment the value stored in config/release every
2060 :     time CMB.make is invoked.
2061 :    
2062 :     The binfile format is now insensitive to anything beyond the first
2063 :     two components of a version number, so bumping the release does not render
2064 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2065 :     during development without invalidating existing binfiles.
2066 :    
2067 :     In any case, every CMB.make updates the date information in version.sml.

2081 :     Tag: blume-20040927-controls
2082 :     Description:
2083 :    
2084 :     Added two pieces of functionality to the Controls interface:
2085 :    
2086 :     1. val save'restore: 'a control -> unit -> unit
2087 :    
2088 :     grabs the current value of the control in stage 1 and restores it
2089 :     in stage 2.
2090 :    
2091 :     2. val set' : 'a control * 'a -> unit -> unit
2092 :    
2093 :     stores the given value into the control in stage 2 (i.e., delayed)
2094 :     but does all error checking in stage 1.
2095 :     (This is for string controls that need to do parse their argument --
2096 :     something that might fail. In some cases, notably in CM, one
2097 :     already knows the intended argument but wants to delay the actual
2098 :     assignment until a time when error recovery would be more difficult.)
2099 :    
2100 :     Changed the handling of controls in tool arguments to classes "sml" and
2101 :     "lazysml":
2102 :     - use Controls.save'restore as a more robust way of restoring the
2103 :     old value (in particular: without having to re-parse the string)
2104 :     - use controls to handle the "overload" keyword in the init group
2105 :     (I believe this change actually fixes a long-standing obscure bug.)

2110 :     Tag: blume-20040927-lazysml
2111 :     Description:
2112 :    
2113 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2114 :     difference to "sml" is that compilation is done with Control.lazysml
2115 :     set to true. A source of class "lazysml" is automatically recognized
2116 :     by a file name suffix of ".lml".
2117 :    
2118 :     In addition to the above feature, the original class "sml" now also
2119 :     supports a tool argument "lazy" which has the same effect. As a
2120 :     result, the following three lines are equivalent:
2121 :    
2122 :     foo.sml : lazysml
2123 :     foo.sml : sml (lazy)
2124 :     foo.sml (lazy)
2125 :    
2126 :     The setting goes into effect both during parsing and during
2127 :     compilation. The original setting is restored right after parsing and
2128 :     after compilation, respectively.
2129 :    
2130 :     In addition to all the above, there is also a general mechanism to set
2131 :     ANY of the "controls" that are available at the command line via
2132 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2133 :     apply as well. (In fact, "lazy" is implemented as a special case of
2134 :     the general mechanism.)
2135 :    
2136 :     The .cm file syntax uses a new keyword tool argument called "with".
2137 :     There are several ways of indicating the desired settings:
2138 :    
2139 :     foo.sml (with:parser.quotations=true)
2140 :     foo.sml (with:(name:parser.quotations value:true))
2141 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2142 :     foo.sml (with:(name1=value1 name2=value2 ...))
2143 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2144 :    
2145 :     etc.
2146 :    
2147 :     Another possible abbreviation is to leave out the =v or value:v part
2148 :     if the name refers to a boolean control (in which case the value is
2149 :     taken to be true). Thus, one could get lazy sml also by saying:
2150 :    
2151 :     foo.sml (with:parser.lazy-keyword=true)
2152 :     foo.sml (with:parser.lazy-keyword)
2153 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2154 :     foo.sml (with:(name:parser.lazy-keyword))

2474 :    
2475 :     Note: 1. You have to make a new, clean build of the runtime system.
2476 :     2. There are new BOOTFILES, you have to use them!
2477 :     (Doing the bootstrap process yourself would be *very* painful!
2478 :     If you absolutely have to do it, build the system under
2479 :     a different architecture and then cross-compile.)
2480 :    
2481 :     Version bumped to 110.46.1 to account for runtime data format changes.

2505 :     Tag: blume-20040617-timer-unix
2506 :     Description:
2507 :    
2508 :     Changed the interface of structures Timer and Unix to match the most
2509 :     recent Basis spec.
2510 :    
2511 :     In the case of Unix there still seems to be an open/weird issue:
2512 :    
2513 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2514 :     fresh streams whenever they are called -- as opposed to have them
2515 :     return the same stream every time. This design is supposed to
2516 :     prevent space leaks caused by proc values hanging on to streams.
2517 :    
2518 :     The reap function, on the other hand, is supposed to close the
2519 :     streams. This cannot be done without having a handle on the
2520 :     stream in proc after all...
2521 :    
2522 :     I took the liberty to implement the following stopgap solution:
2523 :    
2524 :     The proc value hangs on to the most recently created stream(s).
2525 :     Reap closes those. If either or both of the two streams hadn't
2526 :     been created at all yet, then reap will close the corresponding
2527 :     file descriptors directly.
2528 :    
2529 :     PS: I don't understand the original space leak argument anymore. If
2530 :     a proc hangs on to the imperative stream, then I/O operations on those
2531 :     will advance the state of the cached stream and avoid the space leak.

2544 :     Tag: blume-20040525-group-owner
2545 :     Description:
2546 :    
2547 :     CM now ignores (but still accepts) the "owner" information in group
2548 :     descriptions. The owner of a group is its next enclosing
2549 :     library. Each group must have a unique owner. (There is a virtual
2550 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2551 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2552 :     and CM would check that such a declaration is correct. The new scheme
2553 :     is to have CM check that for each group there is precisely one owning
2554 :     library.
2555 :    
2556 :     The advantage of the new scheme is that the programmer no longer needs
2557 :     to maintain the somewhat annoying owner information. The downside is
2558 :     that CM cannot enforce the ownership rule across multiple runs of
2559 :     CM.make. Fortunately, enclosing the same group in two different
2560 :     libraries A and B which are not part of the same program does not
2561 :     cause real problems.

2580 :     Description:
2581 :    
2582 :     Arranged for ml-build to clean up after itself a little bit better.
2583 :     The script generates a temporary SML source file and compiles it using
2584 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
2585 :     gets rid of those at the end, so they don't accumulate under .cm.
2586 :    
2587 :     This required a minor change to install.sh because the name of the
2588 :     metadata directory (default: .cm) is actually configurable at
2589 :     installation time.

2605 :    
2606 :     Added previously missing support for many socket-related functions
2607 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
2608 :     for the voluminous patch!
2609 :    
2610 :     (I have not tested this patch under win32 yet.)
2611 :    
2612 : mblume 1490 Here is David's e-mail:
2613 :    
2614 :     Hi,
2615 :    
2616 :     Attached to this email you find a diff against sml/nj 110.45
2617 :     that will enable socket support under Windows.
2618 :    
2619 :     To apply the patch (using unix or cygwin)
2620 :     1) gunzip runtime.diff.gz
2621 :     2) "cd" into "src/runtime" in the source tree of a fresh
2622 :     110.45 installation.
2623 :     3) patch -p 1 < [your/path/to]runtime.diff
2624 :    
2625 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2626 :     I only ran a few tests for basic socket client functionality
2627 :     (which worked fine). Especially the functions that use ioctl
2628 : mblume 1490 are not tested at all and might not work (see below).
2629 :    
2630 :     I implemented this since we want to move to a newer version of sml/nj
2631 :     but need socket support in order to use it. This is the first time I
2632 :     even had a look at the sml/nj source, so please review my changes
2633 :     before making this part of the distribution! Here are a few issues
2634 : blume 2155 that I think might be better for someone to solve who is more
2635 : mblume 1490 familiar with the sml/nj source (and socket programming):
2636 :    
2637 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2638 :     exception since I could not figure out what the windows equivalent
2639 :     of these functions is
2640 :    
2641 :     - In sockets-osdep.h there are a some #include statements that are
2642 :     only used in a few files that include sockets-osdep.h
2643 :    
2644 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2645 :     does not process its return value since I don't know how to
2646 :     report an error upwards.
2647 :    
2648 :     - It would probably be good to have a call to WSACleanup() when
2649 : blume 2155 the library is unloaded (if there is such a possibility).
2650 : mblume 1490 Otherwise I think Windows will take care of this automatically
2651 :     when the process finishes.
2652 :    
2653 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2654 :     no idea if that is actually the proper replacement on Windows.
2655 :    
2656 :     - All these issues are marked in the code by "FIXME" comments.
2657 :    
2658 : blume 2155 We use sml/nj extensively in our products and are quite happy
2659 :     with it. I hope this contribution will help you.
2660 : mblume 1490
2661 :     Keep up the good work!

2884 :     Description:
2885 :    
2886 :     I modified the read-eval-print loop so that the autoloader gets
2887 :     invoked whenever the prettyprinter tries to look up a symbol that
2888 :     is not currently defined in the toplevel environment but which
2889 :     appears in CM's autoload registry. As a result, we see far fewer of
2890 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
2891 :    
2892 :     In addition to this I tried to clean up some pieces of the Basis
2893 :     implementation (e.g., Socket, Word8Array) in order to prevent other
2894 :     instances of these ?.Foo.Bar.xxx names from being printed.
2895 :    
2896 :     The mechanism that picks names for types still needs some work, though.
2897 :     (Right now it seems that if there is a type A.t which is defined to
2898 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
2899 :     "?.B.u" although the perhaps more sensible solution would be to use
2900 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
2901 :     a chain of DEFtycs not farther than there are corresponding toplevel
2902 :     names in the current environment.)

2908 :     Description:
2909 :    
2910 :     Another installer tweak: All the ML code for the installer is now
2911 :     compiled during CMB.make and put into a little library called
2912 :     $smlnj/installer.cm. The installation then simply invokes
2913 :    
2914 :     sml -m $smlnj/installer.cm
2915 :    
2916 :     and everything happens automagically.
2917 :    
2918 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
2919 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
2920 :     and BINDIR.
2921 :    
2922 :     The new scheme guarantees that the ML code responsible for the installation
2923 :     is in sync with the APIs of the main system. Also, the installer is
2924 :     somewhat faster because the installer script is precompiled.

2932 :     Added a signature SYNCHRONOUS_SOCKET to basis.cm. This is like SOCKET
2933 :     but excludes all non-blocking operations. Defined SOCKET (in Basis)
2934 :     and CML_SOCKET in terms of SYNCHRONOUS_SOCKET. Removed superfluous

2936 :     structure.

2941 :     Tag: blume-20030924-sockets
2942 :     Description:
2943 :    
2944 :     1. Fixed SOCKET API and implementation to match Basis spec.
2945 :     This required changing the internal representation of sockets to one
2946 :     that remembers (for each socket file descriptor) whether it is currently
2947 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
2948 :     call is made only if the state actually needs to change).
2949 :    
2950 :     2. OS-specific details of sockets were moved into separate files, thus
2951 :     making it possible to unify the bulk of the socket implementations
2952 :     between Unix and Win32.
2953 :    
2954 :     3. CML's socket API changed accordingly.
2955 :     (Note that we need to remove non-blocking functions from this API
2956 :     since they are redundant in the case of CML!)
2957 :    
2958 :     4. CML's socket implementation now makes use of non-blocking functions
2959 :     provided by Basis, thus removing all OS-dependent code from this part
2960 :     of CML.
2961 :    
2962 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3075 :     Description:
3076 :    
3077 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3078 :     Modified config/install.bat to take advantage of it. Also modified
3079 :     config/install.sh (and called it config/new-install.sh) to take advantage
3080 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3081 :     independent.)
3082 :    
3083 :     The installer can now install everything under Win32
3084 :     as well as under *nix as long as it compiles.
3085 :    
3086 :     Other changes:
3087 :    
3088 :     - made CML compile again under Win32
3089 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3090 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3091 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3092 :     same as type int; under Win32 it isn't
3093 :     - fixed some slice-related problems in the win32-specific parts of CML
3094 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3095 :     (under Win32, the volume name is case-insensitive, and the
3096 :     OS.Path code compares volume names for equality)

3113 : mblume 1350 Description:
3114 :    
3115 :     1. Changed interface to vectors and arrays in Basis to match
3116 :     (draft) Basis spec.
3117 :     2. Added signatures and implementations of slices according to
3118 :     Basis spec.
3119 :     3. Edited source code throughout the system to make it compile again
3120 :     under 1. and 2. (In some cases code had to be added to have it
3121 :     match the new signatures.)
3122 :     4. MLRISC should be backward-compatible: the copies of the originals
3123 :     of files that needed to change under 3. were retained, the .cm files
3124 :     check the compiler version number and use old versions when
3125 :     appropriate.
3126 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3127 :     dirstream -> string option (in accordance with Basis spec).
3128 :     6. When generating code that counts lines, ml-lex used function
3129 :     CharVector.foldli, taking advantage of its old interface.
3130 :     This has been replaced with the corresponding code from
3131 :     CharVectorSlice. (html-lex must be re-lexed!)
3132 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3133 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3134 :     8. Removed temporary additions (fromInternal, toInternal) from the
3135 :     (now obsolete) IntInf in smlnj-lib/Util.
3136 :     9. Cleaned up structure Byte.
3137 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3138 :     Cleaned/corrected implementation of Date.
3139 :     (Still need to check for correctness; implement better canonicalizeDate.)
3140 :     11. Added "scan" to signature IEEE_REAL.
3141 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3142 :     mod and rem when second operand is 2 (for parity checks).]
3143 :     13. Changed representation of type Time.time, using a single IntInf.int
3144 :     value counting microseconds. This considerably simplified the
3145 :     implementation of structure Time. We now support negative time
3146 :     values; scan and fromString handle signs.
3147 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3148 :     ArraySlice).

3154 :     Description:
3155 :    
3156 :     This is a major update which comes with a version number bump
3157 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3158 :     and an implementation of IntInf in the Basis.
3159 :    
3160 :     There are a fairly large number of related changes and updates throughout
3161 :     the system:
3162 :    
3163 :     Basis:
3164 :     - Implemented IntInf.
3165 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3166 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3167 : mblume 1347 - Added FixedInt as a synonym for Int32.
3168 :    
3169 :     compiler:
3170 :     * Added support for a built-in intinf type.
3171 :     - literals
3172 :     - pattern matching
3173 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3174 :     - overloading on literals and operations
3175 :    
3176 :     This required adding a primitive type intinf, some additional
3177 :     primops, and implementations for several non-trivial intinf
3178 :     operations in Core. (The intinf type is completely abstract
3179 :     to the compiler; all operations get delegated back to the Core.)
3180 :    
3181 :     * Intinf equality is handled by polyequal. However, the compiler
3182 :     does not print its usual warning in this case (since polyequal
3183 :     is the right thing to do there).
3184 :    
3185 :     * Improved the organization of structure InlineT.
3186 :    
3187 :     * A word about conversion primops:
3188 :     If conversions involving intinf do not cancel out during
3189 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3190 : mblume 1347 Since all core access must be resolved already during the FLINT
3191 :     translate phase, it would be too late a the time of CPS contract
3192 : mblume 1348 to add new Core calls. For this reason, conversion primops
3193 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3194 :     they are supposed to convert, and 2. the Core function that
3195 :     can help with this conversion if necessary. If CPS contract
3196 : mblume 1348 eliminates a primop, then the associated Core function becomes
3197 :     dead and goes away. Intinf conversion primops that do not get
3198 :     eliminated by CPS contract get rewritten into calls of their
3199 :     core functions by a separate, new phase.
3200 : mblume 1347
3201 :     interactive system:
3202 :     - Control.Print.intinfDepth controls max length of intinf constants
3203 :     being printed. (Analogous to Control.Print.stringDepth.)
3204 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3205 :     duplicates; replaced some of the code with code that makes better
3206 :     use of library functionality.
3207 :    
3208 :     CM:
3209 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3210 :     are no longer silent.
3211 :    
3212 :     CKIT:
3213 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3214 :     in favor of LargeInt -- which is now the same as IntInf.
3215 :     CKIT-knowledgable people should check whether this is what's
3216 :     intended and otherwise change things back to using Int32 or
3217 :     FixedInt.
3218 :    
3219 :     Throughout the code:
3220 : mblume 1348 Started using IntInf.int literals and built-in operations
3221 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3254 :     - There are a number of simple .bat scripts that substitute for their
3255 :     corresponding Unix shell-scripts. (See below.)
3256 :    
3257 :     - The internals of ml-build have been modified slightly. The main
3258 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3259 :     using OS.Process.system, the ML process delegates this task back
3260 :     to the script. Otherwise problems arise in mixed environments such
3261 :     as Cygwin where scripts look and work like Unix scripts, but
3262 :     where OS.Process.system cannot run them.
3263 :    
3264 :     - In CM, the srcpath pickler used native pathname syntax -- which
3265 :     is incorrect in the case of cross-compilation. The new pickle format
3266 :     is independent of platform-specific naming conventions.
3267 :    
3268 :     - Path configuration files (such as lib/pathconfig) can now choose
3269 :     between native and standard syntax. Placing a line of the form
3270 :    
3271 :     standard!
3272 :    
3273 :     into the file causes all subsequent paths to be interpreted using
3274 :     CM standard pathname syntax (= Unix conventions); a line
3275 :    
3276 :     native!
3277 :    
3278 :     switches back to native style. This was needed so that
3279 :     path config files can be written portably, see src/system/pathconfig.
3280 :    
3281 :     - Runtime system:
3282 :    
3283 :     - win32-filesys.c: get_file_time and set_file_time now
3284 :     access modification time, not creation time.
3285 :    
3286 :     - I/O code made aware of new array representation.
3287 :    
3288 :     - Bug fixes in X86.prim.masm.
3289 :    
3290 :     - src/system/makeml made aware of win32. (For use under cygwin
3291 :     and other Unix-environments for windows.)
3292 :    
3293 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3294 :     which caused BinIO.inputAll to fail consistently.
3295 :    
3296 :     .bat scripts:
3297 :    
3298 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3299 :    
3300 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3301 :     applications (sml, ml-yacc, ml-lex).
3302 :     - ml-build.bat: analogous to ml-build.
3303 :     - config\install.bat: Analogous to config/install.sh. This requires
3304 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3305 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3306 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3307 :     and the bootfile hierarchy must have been unpacked under
3308 :     sml.boot.x86-win32.
3309 :     The script is very primitive and does a poor job at error checking.
3310 :     It only installs the base system, ml-lex, and ml-yacc. No other
3311 :     libraries are being installed (i.e., you get only those that
3312 :     are part of the compiler.)
3313 :     - link-sml.bat: analogous to .link-sml, but not currently used
3314 :    
3315 :     Unrelated bug fixes:
3316 :    
3317 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3318 :     types.
3319 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3320 :     otherwise.)

3357 :     Description:
3358 :    
3359 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3360 :    
3361 :     This mainly affects the quality of error messages. However, some
3362 :     of the code is now more straightforward than before. (Treatment of
3363 :     the above four constructs in translate.sml is much simpler than
3364 :     the "macro-expansion" that was going on before. Plus, the mach-
3365 :     compiler no longer gets invoked just to be able to compile an
3366 :     if-expression.)
3367 :    
3368 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3369 :     interactive loop.

3382 :     o Ctrl-C handling may be flaky.
3383 :     o Windows system calls and Windows I/O are not supported.

3385 :     A new set of binfiles is located at:

3387 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3388 :

3672 :     such as TEXT, DATA, and BSS directives are assumed to be global
3673 :     declarations and are emitted first in the assembly file. This is
3674 :     useful in a number of situations where one has pseudo-ops that are not
3675 :     specific to any segment, and also works around the constraint that one
3676 :     cannot have client pseudo-ops in the TEXT segment.
3677 :    
3678 :     Because no segment is associated with these declarations it is
3679 :     an error to allocate any space or objects before the first segment
3680 :     directive and an exception will be raised. However, we cannot make
3681 :     this check for client pseudo-ops.
3682 :    
3683 :     These top level declarations are a field in the CFG graph_info.
3684 :     In theory you can continue to add to this field after the CFG has been
3685 :     built -- provided you know what you are doing;-)

3691 :     Description:
3692 :    
3693 :     A few minor bugfixes:
3694 :    
3695 :     - Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
3696 :     (Bogus printouts for redefined bindings still occur. Compiler
3697 :     bug should no longer occur now. We need to redo the prettyprinter
3698 :     from scratch.)
3699 :    
3700 :     - CM pathname printer now also adds escape sequences for ( and )
3701 :

3708 :     Description:
3709 :    
3710 :     Applied the following bugfix provided by Emden Gansner:
3711 :    
3712 :     Output is corrupted when outputSubstr is used rather than output.
3713 :    
3714 : blume 2155 The problem occurs when a substring
3715 : blume 1189
3716 :     ss = (s, dataStart, dataLen)
3717 :    
3718 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3719 :     avail bytes of s, starting at index dataStart, are copied into the
3720 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3721 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3722 :     starting this copy at index dataStart+avail in s, the current code
3723 : blume 1189 starts the copy at index avail.
3724 :    
3725 :     Fix:
3726 :     In text-io-fn.sml, change line 695 from
3727 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3728 : blume 2155 to
3729 : blume 1189 val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

3745 :     Description:
3746 :    
3747 :     Added full support for div/mod/rem/quot on the x86, using the machine
3748 :     instruction's two results (without clumsily recomputing the remainder)
3749 :     directly where appropriate.
3750 :    
3751 :     Some more extensive power-of-two support was added to the x86 instruction
3752 :     selector (avoiding expensive divs, mods, and muls where they can be
3753 :     replaced with cheaper shifts and masks). However, this sort of thing
3754 :     ought to be done earlier, e.g., within the CPS optimizer so that
3755 :     all architectures benefit from it.
3756 :    
3757 :     The compiler compiles to a fixed point, but changes might be somewhat
3758 :     fragile nevertheless. Please, report any strange things that you might
3759 :     see wrt. div/mod/quot/rem...

3765 :     Description:
3766 :    
3767 :     Fixed my broken div/mod logic. Unfortunately, this means that the
3768 :     inline code for div/mod now has one more comparison than before.
3769 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3770 :     The problem was with quotient = 0, because that alone does not tell
3771 :     us which way the rounding went. One then has to look at whether
3772 :     remainder and divisor have the same sign... :(
3773 :

3780 :     Description:
3781 :    
3782 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
3783 :    
3784 :     Primops have changed. This means that the bin/boot-file formats have
3785 :     changed as well.
3786 :    
3787 :     To make sure that there is no confusion, I made a new version.
3788 :    
3789 :    
3790 :     CHANGES:
3791 :    
3792 :     * removed REMT from mltree (remainder should never overflow).
3793 :    
3794 :     * added primops to deal with divisions of all flavors to the frontend
3795 :    
3796 :     * handled these primops all the way through so they map to their respective
3797 :     MLRISC support
3798 :    
3799 :     * used these primops in the implementation of Int, Int32, Word, Word32
3800 :    
3801 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3802 :    
3803 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
3804 :    
3805 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3806 :     floating point
3807 :    
3808 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3809 :     and Real (but Real.abs maps to a separate floating-point-only primop)
3810 :    
3811 :    
3812 :     TODO items:
3813 :    
3814 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
3815 :     instructions because the machine instruction encoder cannot handle
3816 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
3817 :     REM in the first place, and REM is supported by the x86 machine coder.)
3818 :    
3819 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
3820 :     selection phase. (The two can be streamlined because the hardware
3821 :     delivers both quotient and remainder at the same time anyway.)
3822 :    
3823 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
3824 :     (Currently the behavior is inconsistent both across architectures and
3825 :     wrt. the draft Basis spec.)
3826 :    
3827 :     * Word8 should eventually be handled natively, too.
3828 :    
3829 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
3830 :     as if there currently is no execution path that could trigger it in
3831 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
3832 :     hold for things like multiplication and division.)

3837 :     Tag: blume-20020327-mlrisc-divisions
3838 :     Description:
3839 :    
3840 :     Added support for all four division operations (ML's div, mod, quot,
3841 :     and rem) to MLRISC. In the course of doing so, I also rationalized
3842 :     the naming (no more annoying switch-around of DIV and QUOT), by
3843 :     parameterizing the operation by div_rounding_mode (which can be either
3844 :     DIV_TO_ZERO or DIV_TO_NEGINF).
3845 :    
3846 :     The generic MLTreeGen functor takes care of compiling all four
3847 :     operations down to only round-to-zero div.
3848 :    
3849 :     Missing pieces:
3850 :    
3851 :     * Doing something smarter than relying on MLTreeGen on architectures
3852 :     like, e.g., the x86 where hardware division delivers both quotient and
3853 :     remainder at the same time. With this, the implementation of the
3854 :     round-to-neginf operations could be further streamlined.
3855 :    
3856 :     * Remove inlining support for div/mod/rem from the frontend and replace it
3857 :     with primops that get carried through to the backend. Do this for all
3858 :     int and word types.

3863 :     Tag: blume-20020325-divmod
3864 :     Description:
3865 :    
3866 :     I improved (hopefully without breaking them) the implementation of Int.div,
3867 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
3868 :     advantage of the following observations:
3869 :    
3870 :     Let q = x quot y r = x rem y
3871 :     d = x div y m = x mod y
3872 :    
3873 :     where "quot" is the round-to-zero version of integer division that
3874 :     hardware usually provides. Then we have:
3875 :    
3876 :     r = x - q * y where neither the * nor the - will overflow
3877 :     d = if q >= 0 orelse x = q * y then q else q - 1
3878 :     where neither the * nor the - will overflow
3879 :     m = if q >= 0 orelse r = 0 then r else r + y
3880 :     where the + will not overflow
3881 :    
3882 :     This results in substantial simplification of the generated code.
3883 :     The following table shows the number of CFG nodes and edges generated
3884 :     for
3885 :     fun f (x, y) = x OPER y
3886 :     (* with OPER \in div, mod, quot, rem *)
3887 :

3927 :     Description:
3928 :    
3929 :     1. Changes to FLINT primops:
3930 :    
3931 :     (* make a call to a C-function;
3932 :     * The primop carries C function prototype information and specifies
3933 :     * which of its (ML-) arguments are floating point. C prototype
3934 :     * information is for use by the backend, ML information is for
3935 :     * use by the CPS converter. *)
3936 :     | RAW_CCALL of { c_proto: CTypes.c_proto,
3937 :     ml_args: ccall_type list,
3938 :     ml_res_opt: ccall_type option,
3939 :     reentrant : bool
3940 :     } option
3941 :     (* Allocate uninitialized storage on the heap.
3942 :     * The record is meant to hold short-lived C objects, i.e., they
3943 : blume 2155 * are not ML pointers. With the tag, the representation is
3944 : leunga 1174 * the same as RECORD with tag tag_raw32 (sz=4), or tag_fblock (sz=8)
3945 :     *)
3946 : blume 2155 | RAW_RECORD of {tag:bool,sz:int}
3947 : leunga 1174 and ccall_type = CCALL_INT32 | CCALL_REAL64 | CCALL_ML_PTR
3948 :    
3949 :     2. These CPS primops are now overloaded:
3950 :    
3951 :     rawload of {kind:numkind}
3952 :     rawstore of {kind:numkind}
3953 :    
3954 :     The one argument form is:
3955 :    
3956 :     rawload {kind} address
3957 :    
3958 :     The two argument form is:
3959 : blume 2155
3960 : leunga 1174 rawload {kind} [ml object, byte-offset]
3961 :    
3962 :     3. RAW_CCALL/RCC now takes two extra arguments:
3963 :    
3964 :     a. The first is whether the C call is reentrant, i.e., whether
3965 :     ML state should be saved and restored.
3966 :     b. The second argument is a string argument specifying the name of
3967 :     library and the C function.
3968 :    
3969 :     These things are currently not handled in the code generator, yet.
3970 :    
3971 :     4. In CProto,
3972 :    
3973 : blume 2155 An encoding type of "bool" means "ml object" and is mapped into
3974 :     C prototype of PTR. Note that "bool" is different than "string",
3975 : leunga 1174 even though "string" is also mapped into PTR, because "bool"
3976 :     is assigned an CPS type of BOGt, while "string" is assigned INT32t.
3977 :    
3978 :     5. Pickler/unpicker
3979 :    
3980 :     Changed to handle RAW_RECORD and newest RAW_CCALL
3981 :    
3982 :     6. MLRiscGen,
3983 :    
3984 :     1. Changed to handle the new rawload/rawstore/rawrecord operators.
3985 :     2. Code for handling C Calls has been moved to a new module CPSCCalls,
3986 :     in the file CodeGen/cpscompile/cps-c-calls.sml
3987 :    
3988 :     7. Added the conditional move operator
3989 :    
3990 :     condmove of branch
3991 :    
3992 : blume 2155 to cps. Generation of this is still buggy so it is currently

4000 :    
4001 : blume 2155 Implemented the Ball-Larus branch prediction-heuristics, and
4002 : george 1168 incorporated graphical viewers for control flow graphs.
4003 :    
4004 : george 1171 Ball-Larus Heuristics:
4005 : george 1168 ---------------------
4006 :     See the file compiler/CodeGen/cpscompile/cpsBranchProb.sml.
4007 :    
4008 :     By design it uses the Dempster-Shafer theory for combining
4009 :     probabilities. For example, in the function:
4010 :    
4011 :     fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)
4012 :    
4013 :     the ball-larus heuristics predicts that the n=0 is unlikely
4014 :     (OH-heuristic), and the 'then' branch is unlikely because of the
4015 :     RH-heuristic -- giving the 'then' branch an even lower combined
4016 : george 1171 probability using the Dempster-Shafer theory.
4017 : george 1168
4018 :     Finally, John Reppy's loop analysis in MLRISC, further lowers the
4019 :     probability of the 'then' branch because of the loop in the else
4020 :     branch.
4021 :    
4022 :    
4023 :     Graphical Viewing:
4024 : blume 2155 ------------------
4025 : george 1168 I merely plugged in Allen's graphical viewers into the compiler. The
4026 :     additional code is not much. At the top level, saying:
4027 :    
4028 :     Control.MLRISC.getFlag "cfg-graphical-view" := true;
4029 :    
4030 :     will display the graphical view of the control flow graph just before
4031 :     back-patching. daVinci must be in your path for this to work. If
4032 :     daVinci is not available, then the default viewer can be changed
4033 :     using:
4034 :    
4035 :     Control.MLRISC.getString "viewer"
4036 :    
4037 :     which can be set to "dot" or "vcg" for the corresponding viewers. Of
4038 :     course, these viewers must be in your path.
4039 :    
4040 :     The above will display the compilation unit at the level of clusters,
4041 :     many of which are small, boring, and un-interesting. Also setting:
4042 :    
4043 :     Control.MLRISC.getInt "cfg-graphical-view_size"
4044 :    
4045 :     will display clusters that are larger than the value set by the above.

4093 : blume 2155 c. Added cases for JP and JNP in X86FreqProps.
4094 :    
4095 : leunga 1156 3. CFG
4096 :    
4097 :     CFG now has a bunch of methods for edge splitting and merging.
4098 :    
4099 :     4. Machine description.
4100 :    
4101 :     John's simplification of MLTREE_BASIS.fcond broke a few machine
4102 :     description things:
4103 :    
4104 :     rtl-build.{sig,sml} and hppa.mdl fixed.
4105 :    
4106 : blume 2155 NOTE: the machine description stuff in the repository is still broken.
4107 :     Again, I can't put my fixes in because that involves
4108 :     changes to MLTREE.

4114 :     Description:
4115 :    
4116 :     Implemented Knuth-Morris-Pratt string matching in PreString and used
4117 :     it for String.isSubstring, Substring.isSubstring, and
4118 :     Substring.position.
4119 :    
4120 :     (Might need some stress-testing. Simple examples worked fine.)

4126 :     Description:
4127 :    
4128 :     Added a structure C.W and functions convert/Ptr.convert to ml-nlffi-lib.
4129 :    
4130 :     This implements a generic mechanism for changing constness qualifiers
4131 :     anywhere within big C types without resorting to outright "casts".
4132 :     (So far, functions such as C.rw/C.ro or C.Ptr.rw/C.Ptr.ro only let you
4133 :     modify the constness at the outermost level.)
4134 :     The implementation of "convert" is based on the idea of "witness"
4135 :     values -- values that are not used by the operation but whose types
4136 :     "testify" to their applicability. On the implementation side, "convert"
4137 :     is simply a projection (returning its second curried argument). With
4138 :     cross-module inlining, it should not result in any machine code being
4139 :     generated.

4145 :     Description:
4146 :    
4147 :     Provided (preliminary?) implementations for
4148 :    
4149 :     {String,Substring}.{concatWith,isSuffix,isSubstring}
4150 :    
4151 :     and
4152 :    
4153 :     Substring.full
4154 :    
4155 :     Those are in the Basis spec but they were missing in SML/NJ.

4161 :     Description:
4162 :    
4163 :     Controls:
4164 :     ---------
4165 :    
4166 :     1. Factored out the recently-added Controls : CONTROLS stuff and put
4167 :     it into its own library $/controls-lib.cm. The source tree for
4168 :     this is under src/smlnj-lib/Controls.
4169 :    
4170 :     2. Changed the names of types and functions in this interface, so they
4171 :     make a bit more "sense":
4172 :    
4173 :     module -> registry
4174 :     'a registry -> 'a group
4175 :    
4176 :     3. The interface now deals in ref cells only. The getter/setter interface
4177 :     is (mostly) gone.
4178 :    
4179 :     4. Added a function that lets one register an already-existing ref cell.
4180 :    
4181 :     5. Made the corresponding modifications to the rest of the code so that
4182 :     everything compiles again.
4183 :    
4184 :     6. Changed the implementation of Controls.MLRISC back to something closer
4185 :     to the original. In particular, this module (and therefore MLRISC)
4186 :     does not depend on Controls. There now is some link-time code in
4187 :     int-sys.sml that registers the MLRISC controls with the Controls
4188 :     module.
4189 :    
4190 :     CM:
4191 :     ---
4192 :    
4193 :     * One can now specify the lambda-split aggressiveness in init.cmi.
