118 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
119 : blume 2692 Date: 2007/06/06 21:45:00 CDT
120 :     Description:
121 :    
122 :     - Aaron: fixed a number of bugs in ml-ulex.
123 :     - Matthias:
124 :     - added CM control "cm.force-tools"; this is false by default;
125 :     when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
126 :     will be forced to run regardless of whether or not their targets
127 :     are up-to-date
128 :     - changed installer code so that config/install.sh will re-build
129 :     heap images for all tools even if those heap images already existed
130 :    
131 :     ----------------------------------------------------------------------
132 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
133 : blume 2688 Date: 2007/06/04 21:21:00 CDT
134 :     Description:
135 :    
136 :     After Aaron Turon's bug fix for ml-ulex (handling the ^ character
137 :     in legacy mode), re-ran the lexer generator on all lex input files
138 :     and committed the results.
139 :    
140 :     This should fix the problem with ckit and nlffi that was reported
141 :     by Vesa A. Norrman.
142 :    
143 :     ----------------------------------------------------------------------
144 :     Name: Matthias Blume (http://www.tti-c.org/blume/)

152 : dbm 2650 Name: Dave MacQueen (dbm@cs.uchicago.edu)
153 :     Date: 2007/05/31 14:55:00 CDT
154 :     Revision: 2650
155 :     Description:
156 :    
157 :     3rd merge of base from primop-branch-3 into the trunk.
158 :     Additional bug fixes included:
159 :    
160 :     * Timer.cpu_timer, etc. type printing corrected (by making
161 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
162 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
163 :     Stefan Monnier)
164 :    
165 :     ----------------------------------------------------------------------
166 : blume 2645 Name: Matthias Blume (http://www.tti-c.org/blume/)
167 :     Date: 2007/05/31 11:40:00 CDT
168 :     Description:
169 :    
170 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
171 :    
172 :     Also, changed the handling of "no core access": When translate.sml
173 :     needs access to a core exception at a time when the core has not
174 :     been set up yet (this only happens when compiling system/smlnj/init/*),
175 :     then don't bother generating the corresponding tests.
176 :    
177 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
178 :     the exception. Unfortunately, that confuses the plambda type checker.
179 :     Moreover, it does not do any good, because at runtime we don't expect
180 :     such an exception to be ever raised. (The code in system/smlnj/init/*
181 :     has to be written very carefully with this in mind!)

184 : mrainey 2639 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
185 :     Date: 2007/05/29
186 :     Description:
187 :    
188 :     Added FSQRT instructions for the AMD64 code generator.
189 :    
190 :     ----------------------------------------------------------------------
191 : blume 2626 Name: Matthias Blume (http://www.tti-c.org/blume/)
192 :     Date: 2007/05/29 19:00:00 CDT
193 :     Description:
194 :    
195 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
196 :     with an explicit test for zero division. This should fixes several
197 :     regressions and makes it possible for downstream optimization phases
198 :     to treat these operations as "pure" when they are applied to unsigned
199 :     operands.
200 :    
201 :     ----------------------------------------------------------------------
202 : mrainey 2622 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
203 :     Date: 2007/05/29
204 :     Description:
205 :    
206 :     Added the new MLRISC code generator for the AMD64. This version,
207 :     in contrast to the previous one, uses SSE registers and instructions
208 :     for all floating-point computations.
209 :

211 : jhr 2613 Name: John Reppy (http://www.cs.uchicago.edu/~jhr)
212 : jhr 2617 Date: 2007/05/29
213 : jhr 2613 Description:
214 :    
215 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
216 :     for bugs #1415 and #1416. We also now correctly handle format characters that
217 :     lie outside the specified set.
218 : jhr 2613
219 :     ----------------------------------------------------------------------
220 : blume 2610 Name: Matthias Blume (http://www.tti-c.org/blume/)
221 :     Date: 2007/05/23 22:30:00 CDT
222 :     Description:
223 :    
224 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
225 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
226 :    
227 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
228 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
229 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
230 :     while running CMB.make. The point is that the single symbol
231 :     NO_PLUGINS is definde in all three cases.)
232 :    
233 :     I changed the three locations within the sources that get compiled
234 :     during CMB.make where ml-yacc or ml-lex input is processed: When
235 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
236 :     is bypassed.
237 :    
238 :     When bootstrapping new versions of the compiler, there can be
239 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
240 :     are not available or otherwise not operational. In this case one can
241 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
242 :     do so, the following command should be issued at the interactive
243 :     prompt:
244 :    
245 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
246 :    
247 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
248 :     files that normally would be generated by ml-yacc and ml-lex.
249 :     (Copies of these files are in the repository.)

252 : dbm 2603 Name: David MacQueen (dbm@cs.uchicago.edu)
253 :     Date: 2007/5/23 17:23:00 CDT
254 :     Revision: 2603
255 :     Description:
256 :    
257 :     2nd merge of base from primop-branch-3 into the trunk.
258 :     Additional bug fixes included:
259 :     Date.scan and Date.fromString fixed;
260 :     Overloading resolution fixed and some type printing problems corrected.
261 :    
262 :     ----------------------------------------------------------------------
263 : blume 2578 Name: Matthias Blume (http://www.tti-c.org/blume/)
264 : blume 2589 Date: 2007/05/23 09:50:00 CDT
265 :     Description:
266 :    
267 :     Changed the installation mechanism for CM tool plugins. These are
268 :     just libaries and now get installed like ordinary libaries.
269 :    
270 :     There are now a number of new installation targets that give some
271 :     fine-grain control over what classes and suffixes are known, and what
272 :     they will map to.
273 :     See config/targets for details.
274 :    
275 :     The code that caused plugin installation as part of running a
276 :     tool's "build" script has been removed. (The build script is for
277 :     building, not for installing.)
278 :    
279 :     ----------------------------------------------------------------------
280 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
281 : blume 2578 Date: 2007/05/22 11:50:00 CDT
282 :     Description:
283 :    
284 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
285 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
286 :     CM fail if a shell tool reports a non-success exit status. If
287 :     the control is set to true, then CM will press on after tool failures
288 :     in the event that the target files exist (even though they are
289 :     considered outdated). Turning the control to true can be useful for
290 :     bootstrapping.
291 :

293 : adrassi 2570 Name: Aaron Turon (http://www.cs.uchicago.edu/~adrassi)
294 :     Date: 2007/05/19
295 :     Description:
296 :    
297 :     Merge of ml-lpt revisions for 110.64.
298 :    
299 :     The name of several ml-lpt-lib modules has changed:
300 :     Repair => AntlrRepair
301 :     StreamPos => AntlrStreamPos
302 :     ErrHandlerFn => AntlrErrHandler
303 :     EBNF => AntlrEBNF
304 :    
305 :     The ml-antlr specification format has changed: declarations such as
306 :     %tokens and nonterminal definitions can occur *multiple* times in the
307 :     same specification. The semantics are such that each new declaration
308 :     extends the previous ones. This does not apply to %start or %name,
309 :     of course.
310 :    
311 :     Importing a grammar via %import now includes *all* declarations in from
312 :     the imported grammar, except for %name, %entry, and %start. Tokens
313 :     and nonterminals can be dropped using the new %dropping clause of the
314 :     %import directive; the separate %drop and %extend have been removed.
315 :    
316 :     We now allow optional type annotations on nonterminals, using the %nonterms
317 :     directive as in ml-yacc.
318 :    
319 :     The refcell construct is now implemented using SML's regular reference
320 :     cells, so the :== and !! notation has been deprecated.
321 :    
322 :     The ml-antlr tool now does much more checking of specifications, and
323 :     its error messages have been greatly improved. Error repair for
324 :     generated parsers has been completely rewritten, and is now both
325 :     much faster and more accurate.
326 :    
327 :     ml-ulex is now more lenient with escape codes (non-SML-standard
328 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
329 :     Also, character classes may now include a "-" character at the beginning
330 :     as is standard in most other regexp tools.
331 :    
332 :     All of these changes are documented in the user guide, which has
333 :     been updated and improved with this merge.

337 :     Date: 2007/05/03
338 :     Revision: r2492
339 :     Description:
340 :    
341 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
342 :     Significant changes in FLINT and the front end, mostly having to do
343 :     with a reorganized system for handling primops. Various bug fixes
344 :     and improvements in printing signatures.

349 :     Description:
350 :    
351 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
352 :     The ml-antlr specification format has changed: declarations such as
353 :     %tokens and nonterminal definitions can occur *multiple* times in the
354 :     same specification. The semantics are such that each new declaration
355 :     extends the previous ones. Grammar extension constructs have also
356 :     changed. We now allow type annotations on nonterminals. Finally,
357 :     the refcell construct is now implemented using SML's regular reference
358 :     cells, so the :== and !! notation has been deprecated. All of these
359 :     changes will appear in the 110.64 user guide for ml-lpt.
360 :    
361 :     The ml-antlr tool now does much more checking of specifications, and
362 :     its error messages have been greatly improved. There has also been
363 :     some work on the error repair process for generated parsers, but this
364 :     will be further improved in 110.64.

400 :     Description:
401 :    
402 :     More Basis fixes: The Char.fromString (etc.) functions did not handle
403 :     the "\uxxxx" escape sequence. There is still an outstanding bug with

442 :     Description:
443 :    
444 :     Substantially changed the signature and implementation of AMD64
445 :     SVID. It now looks similar to the ia32 SVID, yet uses staged
446 :     allocation.

483 :     Date: 2007/02/26
484 :     Description:
485 :    
486 :     Added preliminary support in MLRISC for Staged Allocation, a technique
487 :     for specifying calling conventions (see
488 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
489 :     Initially, we plan to use this code to generate C calls for the AMD64.
490 :    
491 :     The staged allocation code base resides in MLRISC/staged-allocation,
492 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

497 :     Description:
498 :    
499 :     Bug fix: when SaveCState was called with two values to save, a subsequent
500 :     GC could cause the RestoreCState to fail because the saved state had been
501 :     promoted to tagless pair.

512 :    
513 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
514 :     of the range -128 ... 127. I've changed the code so that the range
515 :     check is disabled. Only the low order 8 bits of the immediate operand
516 : jhr 2342 are now significant.

523 :    
524 :     Eliminated any mention of lexgen. (Lexgen was an early precursor
525 :     to ml-ulex.)
526 :    
527 :     You should update your admin directory, so the shell scripts for

556 :     Date: 2007/01/31
557 :     Description:
558 :    
559 :     Brought ml-lpt manual up-to-date with the code. Many minor
560 :     improvements to the tools, and a few minor bugfixes. Prepared
561 :     ml-lpt-lib for integration with new UTF8 structure. Changed
562 :     the interface for creating streams in ml-ulex (we now support
563 :     stream creation from several kinds of sources). Overall, the
564 :     tools are now quite stable, and their interfaces are unlikely to
565 :     change in a way that would break compatibility. More work,
566 :     however, is needed in the documentation.

571 :     Description:
572 :    
573 :     Implemented library installer. Moved CM plugin code for
574 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
575 :     their respective trees. Implemented CM plugin for ml-ulex
576 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
577 :     and ml-antlr.
578 :    
579 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
580 :     CM tools. (It turns out to be too messy to do otherwise because
581 :     there is too much code that during installation relies on the presence
582 :     of these tools -- resulting in a tricky ordering problem.)

587 :     Description:
588 :    
589 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
590 :     Modified CM's startup code to use shiftArgs as it processes
591 :     command line arguments. This way, the init code in each .sml-file
592 :     or library that is mentioned at the top level will see only
593 :     those arguments that have not yet been processed at this point.
594 :     In other words, the init code can "seize control" and process the
595 :     remaining command line.

609 :    
610 :     Added the UTF8 structure and signature from the Moby compiler to
611 :     the SML/NJ library (and the CML library). These modules will replace
612 :     the version in the ml-lpt-lib.

651 :     Description:
652 :    
653 :     Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to
654 :     get the c_cc termios data copied correctly. Also moved the allocation
655 :     of the string to avoid problems if it caused a GC.

661 :     Date: 2006/12/08 09:50:00 CST
662 :     Description:
663 :    
664 :     Added code to CM's "standard shell tool" implementation which
665 :     causes it to tolerate (with a warning) the situation where the shell
666 :     command fails (e.g., due to the shell command's non-existence)
667 :     as long as all target files exist.
668 :    
669 :     This makes it possible to, e.g., build ml-yacc from sources even if
670 :     svn checkout messed up the time stamps on files in such a way that
671 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
672 :     be needed to re-process yacc.grm, but obviously it might not yet be
673 :     available at that time.)

679 :    
680 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
681 :     recvVecFromNB' in the SOCKET signature. This error is actually
682 :     in the SML Basis specification too.

687 :     Description:
688 :

690 :     rather than silently pressing on using bogus values.

695 :     Description:
696 :    
697 :     Use Say.vsay for printing the "[autoloading]" message, so
698 :     #set CM.Control.verbose false (or -Ccm.verbose=false) can be used
699 :     to suppress them.

711 : blume 2193 Date: 2006/11/09 14:30:00 CST
712 :     Tag: release-110.60
713 :     Description:
714 :    
715 :     New working release (110.60). NEW BOOTFILES!
716 :    
717 :     This is the first subversion-hosted release. There are also changes
718 :     to the directory layout. Here is a table:
719 :    
720 :     (All pathnames are relative to the SML/NJ "root" directory.)
721 :    
722 :     config -> config
723 :    
724 :     src/cm -> base/cm
725 :     src/compiler -> base/compiler
726 :     src/runtime -> base/runtime
727 :     src/system -> base/system
728 :    
729 :     src/cm/pgraph -> pgraph
730 :    
731 :     src/READMES -> base/READMES
732 :     src/$notefile -> base/NOTES/$notefile
733 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
734 :     MACOSXINSTALL WININSTALL
735 :    
736 :     src/smlnj-lib -> smlnj-lib
737 :     src/MLRISC -> MLRISC
738 :     ckit -> ckit
739 :     src/cml -> cml
740 :     src/eXene -> eXene
741 :     src/heap2asm -> heap2asm
742 :     src/lexgen -> lexgen
743 :     src/ml-burg -> ml-burg
744 :     src/ml-lex -> ml-lex
745 :     src/ml-yacc -> ml-yacc
746 :     src/ml-nlffi-lib -> nlffi/lib
747 :     src/ml-nlffigen -> nlffi/gen
748 :     src/smlnj-c -> smlnj-c
749 :     src/tools/TraceDebugProf -> trace-debug-profile
750 :    
751 :     In addition, there is also a new
752 :    
753 :     ml-lpt
754 :    
755 :     directory containing two new program generator tools: ml-ulex and
756 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
757 :     LL(k) parser generator). These tools are currently "beta-quality"
758 :    
759 :     The latest versios of the sources can now be obtained anonymously
760 :     via subversion. For this, it is useful to first check out
761 :    
762 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
763 :    
764 :     and put the resulting directory on your shell's PATH. This provides
765 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
766 :     and refresh-all.sh.
767 :    
768 :     To create a freshly checked-out copy of the sources, do
769 :    
770 :     checkout-all.sh [dir]
771 :    
772 :     where dir is the optional SML/NJ root directory (default is ".").
773 :    
774 :     This creates the above directory layout. Each subdirectory of
775 :     the root is under individual subversion control. The stat-all.sh
776 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
777 :     each of these subtrees.
778 :    
779 :     ----------------------------------------------------------------------
780 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
781 : blume 2155 Date: 2006/11/02 12:20:00 CST
782 :     Description:
783 :    
784 :     Reorganized directory layout.
785 :    
786 :     This is a temporary solution, more reorganization is to come.
787 :    
788 :     The basic idea is to have a number of toplevel trees, each corresponding
789 :     to a well-defined part of the overall system. Each part can be
790 :     maintained individually, even in separate source repositories,
791 :     although currently we still serve everything out of the main
792 :     smlnj-gforge tree.
793 :    
794 :     Installer and and scripts have been updated to reflect the new
795 :     layout. The installer (base/src/system/smlnj/installer) is now
796 :     "scriptable" to avoid burning too much knowledge about the
797 :     layout into SML source code. The main script used by the installer
798 :     is in config/actions.
799 :    
800 :     The main change is that many of the subdirectories of what used to
801 :     be known as "src" have moved to the toplevel. The "src" directory
802 :     itself has moved down into a subtree called "base". (We may eventually
803 :     get rid of the extra level of indirection represented by "src".)
804 :    
805 :     The layout is now as follows:
806 :    
807 :     toplevel tree name | default repository
808 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
809 :     -------------------+----------------------------------------------------
810 :     config | $gf/config/trunk
811 :     |
812 :     base | $gf/sml/trunk
813 :     |
814 :     smlnj-lib | $gf/smlnj-lib/trunk
815 :     MLRISC | $gf/MLRISC/trunk
816 :     |
817 :     ml-yacc | $gf/ml-yacc/trunk
818 :     ml-lex | $gf/ml-lex/trunk
819 :     ml-burg | $gf/ml-burg/trunk
820 :     lexgen | $gf/lexgen/trunk
821 :     heap2asm | $gf/heap2asm/trunk
822 :     |
823 :     cml | $gf/cml/trunk
824 :     eXene | $gf/eXene/trunk
825 :     ckit | $gf/ckit/trunk
826 :     nlffi | $gf/nlffi/trunk
827 :     |
828 :     smlnj-c | $gf/smlnj-c/trunk
829 :    
830 :     In $gf/admin there are a few useful shell scripts for checking out
831 :     and maintaining the entire collection of trees:
832 :    
833 :     admin/checkout-all.sh [dir]
834 :     -- optionally creates dir and checks out all trees from their
835 :     default repositories; if dir is missing, checkout into .
836 :     admin/refresh-all.sh [dir]
837 :     -- looks at all trees (from the above list) in dir (default: .)
838 :     and runs "svn update" if the tree exists and is under
839 :     subversion control;
840 :     non-existing or non-subversion trees are skipped
841 :     admin/stat-all.sh [dir]
842 :     -- like refresh-all.sh, but runs "svn stat" instead

874 :     way that ml-lex does
875 :    
876 :     * lexgen propagates exceptions the same way that ml-lex does
877 :    
878 :     CML:
879 :     * Fixed a bug in the SyncVar polling functions (iGetPoll,
880 :     mTakePoll, and mGetPoll) that could lead to livelock.

886 :     Description:
887 :    
888 :     Implemented ml-makedepend (i.e., CM.sources) in a better (more robust)

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

1022 :     Description:
1023 :    
1024 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1025 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1026 : blume 2155 at the time when config/preloads is processed, the library has to
1027 : mblume 1878 be referred to by another name. In 110.57 this would be
1028 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm

1085 :     Description:
1086 :    
1087 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1088 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1089 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1090 :     it. Instead, it has the status of "user code", so it should use
1091 :     $/basis.cm to refer to the Basis library. (At least that's true for
1092 :     the purpose of bootstrapping the previous change. In the future it
1093 :     might make sense to have versiontool.cm refer to
1094 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1095 :     compiler itself uses.)
1096 :    
1097 :     Also patched src/system/testml to have it activate those extra anchor
1098 :     bindings in config/extrapathconfig.

1103 :     Tag: blume-22051115-libraries
1104 :     Description:
1105 :    
1106 :     This change affects the way the following libraries are tied into
1107 :     the system:
1108 :    
1109 :     $/basis.cm
1110 :     $/smlnj-lib.cm
1111 :     $/pp-lib.cm
1112 :     $/controls-lib.cm
1113 :     $/html-lib.cm
1114 :     $/ml-yacc-lib.cm
1115 :    
1116 :     These libraries are now internally (as seen from the source code
1117 :     of the implementation itself) known by the following names:
1118 :    
1119 :     $smlnj/basis/basis.cm
1120 :     $smlnj/smlnj-lib/smlnj-lib.cm
1121 :     $smlnj/smlnj-lib/pp-lib.cm
1122 :     $smlnj/smlnj-lib/controls-lib.cm
1123 :     $smlnj/smlnj-lib/html-lib.cm
1124 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1125 :    
1126 :     This makes it possible to work with code that requires different
1127 :     versions of these libraries, and which refers to these libraries using
1128 :     their "default" names (i.e., the first set of names above). In other
1129 :     words, one can un-define or re-define those default names without
1130 :     compromising the proper functioning of the compiler itself.
1131 :    
1132 :     A similar procedure had already been performed for several of the
1133 :     MLRISC libraries that are linked into the compiler. I did some
1134 :     cleanup on this code.
1135 :    
1136 :     A new file in the config directory (named extrapathconfig) is
1137 :     responsible for setting up path anchors that the compiler itself does
1138 :     not need, but that are typically required by user code.

1317 :     Tag: blume-20050516-redump-heap
1318 :     Description:
1319 :    
1320 :     Added mechanism for re-creating a heap file for the interactive system
1321 :     after configuration variables have been changed.
1322 :    
1323 :     CM.redump_heap : string -> unit
1324 :    
1325 :     This is much like SMLofNJ.exportML, but starting from the resulting
1326 : blume 2155 heap does not return to the caller of CM.redump_heap but
1327 : mblume 1792 restarts the interactive system from scratch. The original call of
1328 :     CM.redump_heap does not return but ends the interactive session.
1329 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1330 :    
1331 :     Internally, redump_heap winds the dynamic execution context back to
1332 :     the point where the original heap image was created and re-executes
1333 :     the heap image generation code in the boot code.

1449 :     Tag: blume-20050114-heap2exec
1450 :     Description:
1451 :    
1452 :     Implemented new (but still experimental) heap2exec facility. This is
1453 :     tested under Mac OS X and should work under Linux (will test shortly).
1454 :     It will probably also work on the Sparc (will test some time later).
1455 :    
1456 :     - removed old "HACKED_STANDALONE" hack from runtime
1457 :    
1458 :     To be able to test this, uncomment the request for "heap2asm" in
1459 :     config/targets prior to installation. (Notice that this is different
1460 :     from "heap2exec" mentioned below. Not a typo.)
1461 :    
1462 :     To perform an actual test, run the command
1463 :    
1464 :     $ bin/heap2exec heapfile execfile
1465 :    
1466 :     (You can put heap2exec on your shell's path.)
1467 :    
1468 :     For example, run
1469 :    
1470 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1471 :    
1472 :     This will create a standalone executable called "mly" which you can
1473 :     then invoke directly as a command.

1499 :     data structure access seems to work.)
1500 :    
1501 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1502 :     (On the Mac, it is big-endian. And that's currently our only
1503 :     PPC platform.)

1618 :     Tag: blume-20041124-position
1619 :     Description:
1620 :    
1621 :     The compiler can now be compiled in a mode that makes structure Position
1622 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1623 :     for the time being.
1624 :    
1625 :     To enable 64-bit positions, use the following procedure:
1626 :    
1627 :     1. Start sml
1628 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1629 :     3. Type
1630 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1631 :     4. Run CMB.make() as usual.
1632 :    
1633 :     This is barely tested. The only test so far was a little SML program
1634 :     counting the number of characters in an 8-gigabyte file by
1635 :     reading it character-by-character. That test was successful.
1636 :    
1637 :     In support of 64-bit positions, a number of new functions have been
1638 :     added to the runtime system.

1679 :     Description:
1680 :    
1681 :     - Stripped down the versiontool: It now only handles the version number.
1682 :     The date string is generated at bootstrap time (during makeml).
1683 :    
1684 :     - In a previous commit, fixed a minor issue with how polyequal is being
1685 :     translated. In particular, the code now "looks through" abstractions.
1686 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1687 :     more efficient code. Important examples for where this matters are
1688 :     the new int64 and word64 types.

1703 :     Description:
1704 :    
1705 :     All the pieces of Word64 are now there, with the exception of the
1706 :     conversions from and to LargeWord. (Eventually these need to be identities,
1707 :     but for the time being they don't even make sense because LargeWord is
1708 :     32-bit wide.)
1709 :    
1710 :     Also started to add similar support for Int64, but major pieces of that
1711 :     are still missing.

1717 :     Description:
1718 :    
1719 :     Structure Word64 is now (almost) complete, word literals and patterns
1720 :     seem to work. There are a few odd pieces missing. In particular,
1721 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1722 :     at the moment.
1723 :    
1724 :     Making Word64 official would mean that LargeWord becomes Word64. But
1725 :     this requires extreme care because most word-word conversions have to
1726 :     go through LargeWord, so making a mistake means loss of efficiency or
1727 :     worse. Eventually there will be a solution similar to (but actually
1728 :     simpler than) what I did with IntInf.

1763 :     - Made corresponding changes to config/install.sh and config/unpack.
1764 :     - Default contents of config/srcarchiveurl uses $VERSION and
1765 :     normally does not have to be edited to reflect a version change.
1766 :    
1767 :     (As a result, a version change can be done by just editing
1768 :     config/version, the rest is now automatic.)

1808 :     Tag: blume-20041020-standalone-backtrace
1809 :     Description:
1810 :    
1811 :     Added a mechanism for getting back-trace information from standalone
1812 :     programs. Here is how it works:
1813 :    
1814 :     1. The part of the program from which you want to get backtrace
1815 :     information (usually the whole program) should be wrapped with
1816 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
1817 :     main program could be modified from something like
1818 :    
1819 :     fun main (pgm, args) = ...
1820 :    
1821 :     to
1822 :    
1823 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1824 :    
1825 :     2. To be able to access BackTrace.monitor, you have to add
1826 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
1827 :     main function.
1828 :    
1829 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1830 :     CM might have created in the past for your project).
1831 :    
1832 :     4. Build the system using this command line:
1833 :    
1834 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1835 :     myprog.cm MyProg.main myprog
1836 :    
1837 :     instead of the usual
1838 :    
1839 :     ml-build myprog.cm MyProg.main myprog
1840 :    
1841 :     I changed a library name:
1842 :    
1843 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1844 :    
1845 :     New libraries:
1846 :    
1847 :     $smlnj-tdp/back-trace.cm
1848 :     -- when loaded causes the back-trace plugin to be installed
1849 :     $smlnj-tdp/coverage.cm
1850 :     -- when loaded causes the coverage plugin to be installed

1866 :     Description:
1867 :    
1868 :     * Test coverage tool added!
1869 :     * Further reorganization of tracing-, debugging-, and profiling support:
1870 :    
1871 :     - moved original BTImp -- now called BackTrace -- into a separate
1872 :     library called $/trace-debug-profile.cm
1873 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
1874 :     - only the instrumentation mechanism is now left in the compiler proper
1875 :     - BackTrace module is a plugin which is NOT plugged in by default
1876 :     - Coverage module is another such plugin
1877 :    
1878 :     To get the benefits of any of these plugin modules, the code in
1879 :     question must be compiled with tdp instrumentation turned on. This
1880 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
1881 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1882 :    
1883 :     Plugins are selected at link time. (Pre-compiled instrumented code
1884 :     can be re-loaded with different plugins in effect.) When an
1885 :     instrumented module is linked, whatever plugins are at that time
1886 :     enabled will come into effect for that module.
1887 :    
1888 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
1889 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
1890 :     To enable the coverage plugin, load the same library and invoke
1891 :     Coverage.install().
1892 :    
1893 :     Back-traces are generated automatically on uncaught exceptions and
1894 :     when the code in question explicitly invokes BackTrace.trigger().
1895 :    
1896 :     Coverage (and execution frequency-) information must be queried
1897 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2015 :     Description:
2016 :    
2017 :     Implemented some CM magic to have
2018 :     file src/compiler/TopLevel/main/version.sml
2019 :     generated automagically.
2020 :     The version is taken from two files: config/version and config/release.
2021 :     The first is expected to contain a two-part version number such as 110.49.
2022 :     The second should contain a single number, but it may be missing.
2023 :    
2024 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2025 :     time the version tool is loaded (which is the first time you say CMB.make),
2026 :     then the tool will increment the value stored in config/release every
2027 :     time CMB.make is invoked.
2028 :    
2029 :     The binfile format is now insensitive to anything beyond the first
2030 :     two components of a version number, so bumping the release does not render
2031 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2032 :     during development without invalidating existing binfiles.
2033 :    
2034 :     In any case, every CMB.make updates the date information in version.sml.

2048 :     Tag: blume-20040927-controls
2049 :     Description:
2050 :    
2051 :     Added two pieces of functionality to the Controls interface:
2052 :    
2053 :     1. val save'restore: 'a control -> unit -> unit
2054 :    
2055 :     grabs the current value of the control in stage 1 and restores it
2056 :     in stage 2.
2057 :    
2058 :     2. val set' : 'a control * 'a -> unit -> unit
2059 :    
2060 :     stores the given value into the control in stage 2 (i.e., delayed)
2061 :     but does all error checking in stage 1.
2062 :     (This is for string controls that need to do parse their argument --
2063 :     something that might fail. In some cases, notably in CM, one
2064 :     already knows the intended argument but wants to delay the actual
2065 :     assignment until a time when error recovery would be more difficult.)
2066 :    
2067 :     Changed the handling of controls in tool arguments to classes "sml" and
2068 :     "lazysml":
2069 :     - use Controls.save'restore as a more robust way of restoring the
2070 :     old value (in particular: without having to re-parse the string)
2071 :     - use controls to handle the "overload" keyword in the init group
2072 :     (I believe this change actually fixes a long-standing obscure bug.)

2078 :     Description:
2079 :    
2080 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2081 :     difference to "sml" is that compilation is done with Control.lazysml
2082 :     set to true. A source of class "lazysml" is automatically recognized
2083 :     by a file name suffix of ".lml".
2084 :    
2085 :     In addition to the above feature, the original class "sml" now also
2086 :     supports a tool argument "lazy" which has the same effect. As a
2087 :     result, the following three lines are equivalent:
2088 :    
2089 :     foo.sml : lazysml
2090 :     foo.sml : sml (lazy)
2091 :     foo.sml (lazy)
2092 :    
2093 :     The setting goes into effect both during parsing and during
2094 :     compilation. The original setting is restored right after parsing and
2095 :     after compilation, respectively.
2096 :    
2097 :     In addition to all the above, there is also a general mechanism to set
2098 :     ANY of the "controls" that are available at the command line via
2099 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2100 :     apply as well. (In fact, "lazy" is implemented as a special case of
2101 :     the general mechanism.)
2102 :    
2103 :     The .cm file syntax uses a new keyword tool argument called "with".
2104 :     There are several ways of indicating the desired settings:
2105 :    
2106 :     foo.sml (with:parser.quotations=true)
2107 :     foo.sml (with:(name:parser.quotations value:true))
2108 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2109 :     foo.sml (with:(name1=value1 name2=value2 ...))
2110 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2111 :    
2112 :     etc.
2113 :    
2114 :     Another possible abbreviation is to leave out the =v or value:v part
2115 :     if the name refers to a boolean control (in which case the value is
2116 :     taken to be true). Thus, one could get lazy sml also by saying:
2117 :    
2118 :     foo.sml (with:parser.lazy-keyword=true)
2119 :     foo.sml (with:parser.lazy-keyword)
2120 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2121 :     foo.sml (with:(name:parser.lazy-keyword))

2477 :    
2478 :     In the case of Unix there still seems to be an open/weird issue:
2479 :    
2480 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2481 :     fresh streams whenever they are called -- as opposed to have them
2482 :     return the same stream every time. This design is supposed to
2483 :     prevent space leaks caused by proc values hanging on to streams.
2484 :    
2485 :     The reap function, on the other hand, is supposed to close the
2486 :     streams. This cannot be done without having a handle on the
2487 :     stream in proc after all...
2488 :    
2489 :     I took the liberty to implement the following stopgap solution:
2490 :    
2491 :     The proc value hangs on to the most recently created stream(s).
2492 :     Reap closes those. If either or both of the two streams hadn't
2493 :     been created at all yet, then reap will close the corresponding
2494 :     file descriptors directly.
2495 :    
2496 :     PS: I don't understand the original space leak argument anymore. If
2497 :     a proc hangs on to the imperative stream, then I/O operations on those
2498 :     will advance the state of the cached stream and avoid the space leak.

2511 :     Tag: blume-20040525-group-owner
2512 :     Description:
2513 :    
2514 :     CM now ignores (but still accepts) the "owner" information in group
2515 :     descriptions. The owner of a group is its next enclosing
2516 :     library. Each group must have a unique owner. (There is a virtual
2517 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2518 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2519 :     and CM would check that such a declaration is correct. The new scheme
2520 :     is to have CM check that for each group there is precisely one owning
2521 :     library.
2522 :    
2523 :     The advantage of the new scheme is that the programmer no longer needs
2524 :     to maintain the somewhat annoying owner information. The downside is
2525 :     that CM cannot enforce the ownership rule across multiple runs of
2526 :     CM.make. Fortunately, enclosing the same group in two different
2527 :     libraries A and B which are not part of the same program does not
2528 :     cause real problems.

2547 :     Description:
2548 :    
2549 :     Arranged for ml-build to clean up after itself a little bit better.
2550 :     The script generates a temporary SML source file and compiles it using
2551 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
2552 :     gets rid of those at the end, so they don't accumulate under .cm.
2553 :    
2554 :     This required a minor change to install.sh because the name of the
2555 :     metadata directory (default: .cm) is actually configurable at
2556 :     installation time.

2572 :    
2573 :     Added previously missing support for many socket-related functions
2574 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
2575 :     for the voluminous patch!
2576 :    
2577 :     (I have not tested this patch under win32 yet.)
2578 :    
2579 : mblume 1490 Here is David's e-mail:
2580 :    
2581 :     Hi,
2582 :    
2583 :     Attached to this email you find a diff against sml/nj 110.45
2584 :     that will enable socket support under Windows.
2585 :    
2586 :     To apply the patch (using unix or cygwin)
2587 :     1) gunzip runtime.diff.gz
2588 :     2) "cd" into "src/runtime" in the source tree of a fresh
2589 :     110.45 installation.
2590 :     3) patch -p 1 < [your/path/to]runtime.diff
2591 :    
2592 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2593 :     I only ran a few tests for basic socket client functionality
2594 :     (which worked fine). Especially the functions that use ioctl
2595 : mblume 1490 are not tested at all and might not work (see below).
2596 :    
2597 :     I implemented this since we want to move to a newer version of sml/nj
2598 :     but need socket support in order to use it. This is the first time I
2599 :     even had a look at the sml/nj source, so please review my changes
2600 :     before making this part of the distribution! Here are a few issues
2601 : blume 2155 that I think might be better for someone to solve who is more
2602 : mblume 1490 familiar with the sml/nj source (and socket programming):
2603 :    
2604 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2605 :     exception since I could not figure out what the windows equivalent
2606 :     of these functions is
2607 :    
2608 :     - In sockets-osdep.h there are a some #include statements that are
2609 :     only used in a few files that include sockets-osdep.h
2610 :    
2611 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2612 :     does not process its return value since I don't know how to
2613 :     report an error upwards.
2614 :    
2615 :     - It would probably be good to have a call to WSACleanup() when
2616 : blume 2155 the library is unloaded (if there is such a possibility).
2617 : mblume 1490 Otherwise I think Windows will take care of this automatically
2618 :     when the process finishes.
2619 :    
2620 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2621 :     no idea if that is actually the proper replacement on Windows.
2622 :    
2623 :     - All these issues are marked in the code by "FIXME" comments.
2624 :    
2625 : blume 2155 We use sml/nj extensively in our products and are quite happy
2626 :     with it. I hope this contribution will help you.
2627 : mblume 1490
2628 :     Keep up the good work!

2851 :     Description:
2852 :    
2853 :     I modified the read-eval-print loop so that the autoloader gets
2854 :     invoked whenever the prettyprinter tries to look up a symbol that
2855 :     is not currently defined in the toplevel environment but which
2856 :     appears in CM's autoload registry. As a result, we see far fewer of
2857 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
2858 :    
2859 :     In addition to this I tried to clean up some pieces of the Basis
2860 :     implementation (e.g., Socket, Word8Array) in order to prevent other
2861 :     instances of these ?.Foo.Bar.xxx names from being printed.
2862 :    
2863 :     The mechanism that picks names for types still needs some work, though.
2864 :     (Right now it seems that if there is a type A.t which is defined to
2865 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
2866 :     "?.B.u" although the perhaps more sensible solution would be to use
2867 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow

2869 :     names in the current environment.)

2875 :     Description:
2876 :    
2877 :     Another installer tweak: All the ML code for the installer is now
2878 :     compiled during CMB.make and put into a little library called
2879 :     $smlnj/installer.cm. The installation then simply invokes
2880 :    
2881 :     sml -m $smlnj/installer.cm
2882 :    
2883 :     and everything happens automagically.
2884 :    
2885 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
2886 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
2887 :     and BINDIR.
2888 :    
2889 :     The new scheme guarantees that the ML code responsible for the installation
2890 :     is in sync with the APIs of the main system. Also, the installer is
2891 :     somewhat faster because the installer script is precompiled.

2898 :    
2899 :     Added a signature SYNCHRONOUS_SOCKET to basis.cm. This is like SOCKET
2900 :     but excludes all non-blocking operations. Defined SOCKET (in Basis)
2901 :     and CML_SOCKET in terms of SYNCHRONOUS_SOCKET. Removed superfluous
2902 :     implementations of non-blocking operations from CML's Socket
2903 :     structure.

2908 :     Tag: blume-20030924-sockets
2909 :     Description:
2910 :    
2911 :     1. Fixed SOCKET API and implementation to match Basis spec.
2912 :     This required changing the internal representation of sockets to one
2913 :     that remembers (for each socket file descriptor) whether it is currently
2914 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
2915 :     call is made only if the state actually needs to change).
2916 :    
2917 :     2. OS-specific details of sockets were moved into separate files, thus
2918 :     making it possible to unify the bulk of the socket implementations
2919 :     between Unix and Win32.
2920 :    
2921 :     3. CML's socket API changed accordingly.
2922 :     (Note that we need to remove non-blocking functions from this API
2923 :     since they are redundant in the case of CML!)
2924 :    
2925 :     4. CML's socket implementation now makes use of non-blocking functions
2926 :     provided by Basis, thus removing all OS-dependent code from this part
2927 :     of CML.
2928 :    
2929 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3041 :     Tag: blume-20030909-installer
3042 :     Description:
3043 :    
3044 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3045 :     Modified config/install.bat to take advantage of it. Also modified
3046 :     config/install.sh (and called it config/new-install.sh) to take advantage
3047 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3048 :     independent.)
3049 :    
3050 :     The installer can now install everything under Win32
3051 :     as well as under *nix as long as it compiles.
3052 :    
3053 :     Other changes:
3054 :    
3055 :     - made CML compile again under Win32
3056 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3057 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3058 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3059 :     same as type int; under Win32 it isn't
3060 :     - fixed some slice-related problems in the win32-specific parts of CML
3061 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3062 :     (under Win32, the volume name is case-insensitive, and the
3063 :     OS.Path code compares volume names for equality)

3080 : mblume 1350 Description:
3081 :    
3082 :     1. Changed interface to vectors and arrays in Basis to match
3083 :     (draft) Basis spec.
3084 :     2. Added signatures and implementations of slices according to
3085 :     Basis spec.
3086 :     3. Edited source code throughout the system to make it compile again
3087 :     under 1. and 2. (In some cases code had to be added to have it
3088 :     match the new signatures.)
3089 :     4. MLRISC should be backward-compatible: the copies of the originals
3090 :     of files that needed to change under 3. were retained, the .cm files
3091 :     check the compiler version number and use old versions when
3092 :     appropriate.
3093 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3094 :     dirstream -> string option (in accordance with Basis spec).
3095 :     6. When generating code that counts lines, ml-lex used function
3096 :     CharVector.foldli, taking advantage of its old interface.
3097 :     This has been replaced with the corresponding code from
3098 :     CharVectorSlice. (html-lex must be re-lexed!)
3099 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3100 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3101 :     8. Removed temporary additions (fromInternal, toInternal) from the
3102 :     (now obsolete) IntInf in smlnj-lib/Util.
3103 :     9. Cleaned up structure Byte.
3104 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3105 :     Cleaned/corrected implementation of Date.
3106 :     (Still need to check for correctness; implement better canonicalizeDate.)
3107 :     11. Added "scan" to signature IEEE_REAL.
3108 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3109 :     mod and rem when second operand is 2 (for parity checks).]
3110 :     13. Changed representation of type Time.time, using a single IntInf.int
3111 :     value counting microseconds. This considerably simplified the
3112 :     implementation of structure Time. We now support negative time
3113 :     values; scan and fromString handle signs.
3114 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3115 :     ArraySlice).

3121 :     Description:
3122 :    
3123 :     This is a major update which comes with a version number bump
3124 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3125 :     and an implementation of IntInf in the Basis.
3126 :    
3127 :     There are a fairly large number of related changes and updates throughout
3128 :     the system:
3129 :    
3130 :     Basis:
3131 :     - Implemented IntInf.
3132 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3133 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3134 : mblume 1347 - Added FixedInt as a synonym for Int32.
3135 :    
3136 :     compiler:
3137 :     * Added support for a built-in intinf type.
3138 :     - literals
3139 :     - pattern matching
3140 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3141 :     - overloading on literals and operations
3142 :    
3143 :     This required adding a primitive type intinf, some additional
3144 :     primops, and implementations for several non-trivial intinf
3145 :     operations in Core. (The intinf type is completely abstract
3146 :     to the compiler; all operations get delegated back to the Core.)
3147 :    
3148 :     * Intinf equality is handled by polyequal. However, the compiler
3149 :     does not print its usual warning in this case (since polyequal
3150 :     is the right thing to do there).
3151 :    
3152 :     * Improved the organization of structure InlineT.
3153 :    
3154 :     * A word about conversion primops:
3155 :     If conversions involving intinf do not cancel out during
3156 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3157 : mblume 1347 Since all core access must be resolved already during the FLINT
3158 :     translate phase, it would be too late a the time of CPS contract
3159 : mblume 1348 to add new Core calls. For this reason, conversion primops
3160 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3161 :     they are supposed to convert, and 2. the Core function that
3162 :     can help with this conversion if necessary. If CPS contract
3163 : mblume 1348 eliminates a primop, then the associated Core function becomes
3164 :     dead and goes away. Intinf conversion primops that do not get
3165 :     eliminated by CPS contract get rewritten into calls of their
3166 :     core functions by a separate, new phase.
3167 : mblume 1347
3168 :     interactive system:
3169 :     - Control.Print.intinfDepth controls max length of intinf constants
3170 :     being printed. (Analogous to Control.Print.stringDepth.)
3171 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3172 :     duplicates; replaced some of the code with code that makes better
3173 :     use of library functionality.
3174 :    
3175 :     CM:
3176 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3177 :     are no longer silent.
3178 :    
3179 :     CKIT:
3180 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3181 :     in favor of LargeInt -- which is now the same as IntInf.
3182 :     CKIT-knowledgable people should check whether this is what's
3183 :     intended and otherwise change things back to using Int32 or
3184 :     FixedInt.
3185 :    
3186 :     Throughout the code:
3187 : mblume 1348 Started using IntInf.int literals and built-in operations
3188 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3209 :

3211 :    
3212 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3213 :    
3214 :     This patch restores SML/NJ's ability to run under win32. There are a
3215 :     number of changes, including fixes for several bugs that had gone
3216 :     unnoticed until now:
3217 :    
3218 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3219 :     trying to run the win32 version from within cygwin.)
3220 :    
3221 :     - There are a number of simple .bat scripts that substitute for their
3222 :     corresponding Unix shell-scripts. (See below.)
3223 :    
3224 :     - The internals of ml-build have been modified slightly. The main
3225 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3226 :     using OS.Process.system, the ML process delegates this task back
3227 :     to the script. Otherwise problems arise in mixed environments such
3228 :     as Cygwin where scripts look and work like Unix scripts, but
3229 :     where OS.Process.system cannot run them.
3230 :    
3231 :     - In CM, the srcpath pickler used native pathname syntax -- which
3232 :     is incorrect in the case of cross-compilation. The new pickle format
3233 :     is independent of platform-specific naming conventions.
3234 :    
3235 :     - Path configuration files (such as lib/pathconfig) can now choose
3236 :     between native and standard syntax. Placing a line of the form
3237 :    
3238 :     standard!
3239 :    
3240 :     into the file causes all subsequent paths to be interpreted using
3241 :     CM standard pathname syntax (= Unix conventions); a line
3242 :    
3243 :     native!
3244 :    
3245 :     switches back to native style. This was needed so that
3246 :     path config files can be written portably, see src/system/pathconfig.
3247 :    
3248 :     - Runtime system:
3249 :    
3250 :     - win32-filesys.c: get_file_time and set_file_time now
3251 :     access modification time, not creation time.
3252 :    
3253 :     - I/O code made aware of new array representation.
3254 :    
3255 :     - Bug fixes in X86.prim.masm.
3256 :    
3257 :     - src/system/makeml made aware of win32. (For use under cygwin
3258 :     and other Unix-environments for windows.)
3259 :    
3260 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3261 :     which caused BinIO.inputAll to fail consistently.
3262 :    
3263 :     .bat scripts:
3264 :    
3265 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3266 :    
3267 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3268 :     applications (sml, ml-yacc, ml-lex).
3269 :     - ml-build.bat: analogous to ml-build.
3270 :     - config\install.bat: Analogous to config/install.sh. This requires
3271 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3272 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3273 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3274 :     and the bootfile hierarchy must have been unpacked under
3275 :     sml.boot.x86-win32.
3276 :     The script is very primitive and does a poor job at error checking.
3277 :     It only installs the base system, ml-lex, and ml-yacc. No other
3278 :     libraries are being installed (i.e., you get only those that
3279 :     are part of the compiler.)
3280 :     - link-sml.bat: analogous to .link-sml, but not currently used
3281 :    
3282 :     Unrelated bug fixes:
3283 :    
3284 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3285 :     types.
3286 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3287 :     otherwise.)

3311 :     Description:
3312 :    
3313 :     Two changes:
3314 :    
3315 :     1. Added a flag for controlling whether non-exhaustive bindings will
3316 :     be treated as errors (default is false).

3324 :     Description:
3325 :    
3326 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3327 :    
3328 :     This mainly affects the quality of error messages. However, some
3329 :     of the code is now more straightforward than before. (Treatment of
3330 :     the above four constructs in translate.sml is much simpler than
3331 :     the "macro-expansion" that was going on before. Plus, the mach-
3332 :     compiler no longer gets invoked just to be able to compile an
3333 :     if-expression.)
3334 :    
3335 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3336 :     interactive loop.

3343 :    
3344 : blume 2155 Ported the runtime system to cygwin, which uses the unix

3346 :    
3347 : blume 2155 o getnetbyname, getnetbyaddr: these functions seem to be missing in
3348 : allenleung 1327 the Cygwin library.
3349 :     o Ctrl-C handling may be flaky.
3350 :     o Windows system calls and Windows I/O are not supported.

3352 :     A new set of binfiles is located at:
3353 :    
3354 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3355 :

3513 :     Another small change is that ppDec tries to give more information

3515 :     broken in some mysterious way if the functor's body's signature
3516 :     has not been declared by ascription but gets inferred from the

3617 :    
3618 :     0. John Reppy made several modifications to the SML/NJ library.
3619 :     In particular, there is a shiny new controls-lib.cm.
3620 :    
3621 :     1. Pushed new controls interface through compiler so that everything
3622 :     compiles again.
3623 :    
3624 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3625 :     SML/NJ library (so that CML compiles again).
3626 :    
3627 :     3. Modified init scripts because XXX_DEFAULT environment variables

3636 :     Description:
3637 :    
3638 :     All pseudo-ops emitted before the first segment declaration
3639 :     such as TEXT, DATA, and BSS directives are assumed to be global
3640 :     declarations and are emitted first in the assembly file. This is
3641 :     useful in a number of situations where one has pseudo-ops that are not
3642 :     specific to any segment, and also works around the constraint that one
3643 :     cannot have client pseudo-ops in the TEXT segment.
3644 :    
3645 :     Because no segment is associated with these declarations it is
3646 :     an error to allocate any space or objects before the first segment
3647 :     directive and an exception will be raised. However, we cannot make
3648 :     this check for client pseudo-ops.
3649 :    
3650 :     These top level declarations are a field in the CFG graph_info.
3651 :     In theory you can continue to add to this field after the CFG has been

3681 : blume 2155 The problem occurs when a substring
3682 : blume 1189
3683 :     ss = (s, dataStart, dataLen)
3684 :    
3685 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3686 :     avail bytes of s, starting at index dataStart, are copied into the
3687 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3688 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3689 :     starting this copy at index dataStart+avail in s, the current code
3690 : blume 1189 starts the copy at index avail.
3691 :    
3692 :     Fix:
3693 :     In text-io-fn.sml, change line 695 from
3694 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3695 : blume 2155 to
3696 : blume 1189 val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

3712 :     Description:
3713 :    
3714 :     Added full support for div/mod/rem/quot on the x86, using the machine
3715 :     instruction's two results (without clumsily recomputing the remainder)
3716 :     directly where appropriate.
3717 :    
3718 :     Some more extensive power-of-two support was added to the x86 instruction
3719 :     selector (avoiding expensive divs, mods, and muls where they can be
3720 :     replaced with cheaper shifts and masks). However, this sort of thing
3721 :     ought to be done earlier, e.g., within the CPS optimizer so that
3722 :     all architectures benefit from it.
3723 :    
3724 :     The compiler compiles to a fixed point, but changes might be somewhat
3725 :     fragile nevertheless. Please, report any strange things that you might
3726 :     see wrt. div/mod/quot/rem...

3732 :     Description:
3733 :    
3734 :     Fixed my broken div/mod logic. Unfortunately, this means that the
3735 :     inline code for div/mod now has one more comparison than before.
3736 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3737 :     The problem was with quotient = 0, because that alone does not tell

3747 :     Description:
3748 :    
3749 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
3750 :    
3751 :     Primops have changed. This means that the bin/boot-file formats have
3752 :     changed as well.
3753 :    
3754 :     To make sure that there is no confusion, I made a new version.
3755 :    
3756 :    
3757 :     CHANGES:
3758 :    
3759 :     * removed REMT from mltree (remainder should never overflow).
3760 :    
3761 :     * added primops to deal with divisions of all flavors to the frontend
3762 :    
3763 :     * handled these primops all the way through so they map to their respective
3764 :     MLRISC support
3765 :    
3766 :     * used these primops in the implementation of Int, Int32, Word, Word32
3767 :    
3768 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3769 :    
3770 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
3771 :    
3772 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3773 :     floating point
3774 :    
3775 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3776 :     and Real (but Real.abs maps to a separate floating-point-only primop)
3777 :    
3778 :    
3779 :     TODO items:
3780 :    
3781 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
3782 :     instructions because the machine instruction encoder cannot handle
3783 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
3784 :     REM in the first place, and REM is supported by the x86 machine coder.)
3785 :    
3786 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
3787 :     selection phase. (The two can be streamlined because the hardware
3788 :     delivers both quotient and remainder at the same time anyway.)
3789 :    
3790 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
3791 :     (Currently the behavior is inconsistent both across architectures and
3792 :     wrt. the draft Basis spec.)
3793 :    
3794 :     * Word8 should eventually be handled natively, too.
3795 :    
3796 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
3797 :     as if there currently is no execution path that could trigger it in
3798 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
3799 :     hold for things like multiplication and division.)

3804 :     Tag: blume-20020327-mlrisc-divisions
3805 :     Description:
3806 :    
3807 :     Added support for all four division operations (ML's div, mod, quot,
3808 :     and rem) to MLRISC. In the course of doing so, I also rationalized
3809 :     the naming (no more annoying switch-around of DIV and QUOT), by
3810 :     parameterizing the operation by div_rounding_mode (which can be either
3811 :     DIV_TO_ZERO or DIV_TO_NEGINF).
3812 :    
3813 :     The generic MLTreeGen functor takes care of compiling all four
3814 :     operations down to only round-to-zero div.
3815 :    
3816 :     Missing pieces:
3817 :    
3818 :     * Doing something smarter than relying on MLTreeGen on architectures
3819 :     like, e.g., the x86 where hardware division delivers both quotient and
3820 :     remainder at the same time. With this, the implementation of the
3821 :     round-to-neginf operations could be further streamlined.
3822 :    
3823 :     * Remove inlining support for div/mod/rem from the frontend and replace it
3824 :     with primops that get carried through to the backend. Do this for all
3825 :     int and word types.

3830 :     Tag: blume-20020325-divmod
3831 :     Description:
3832 :    
3833 :     I improved (hopefully without breaking them) the implementation of Int.div,
3834 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
3835 :     advantage of the following observations:
3836 :    
3837 :     Let q = x quot y r = x rem y
3838 :     d = x div y m = x mod y
3839 :    
3840 :     where "quot" is the round-to-zero version of integer division that
3841 :     hardware usually provides. Then we have:
3842 :    
3843 :     r = x - q * y where neither the * nor the - will overflow
3844 :     d = if q >= 0 orelse x = q * y then q else q - 1
3845 :     where neither the * nor the - will overflow
3846 :     m = if q >= 0 orelse r = 0 then r else r + y
3847 :     where the + will not overflow
3848 :    
3849 :     This results in substantial simplification of the generated code.
3850 :     The following table shows the number of CFG nodes and edges generated
3851 :     for
3852 :     fun f (x, y) = x OPER y
3853 :     (* with OPER \in div, mod, quot, rem *)
3854 :

3894 :     Description:
3895 :    
3896 :     1. Changes to FLINT primops:
3897 :    
3898 :     (* make a call to a C-function;
3899 :     * The primop carries C function prototype information and specifies
3900 :     * which of its (ML-) arguments are floating point. C prototype
3901 :     * information is for use by the backend, ML information is for
3902 :     * use by the CPS converter. *)
3903 :     | RAW_CCALL of { c_proto: CTypes.c_proto,
3904 :     ml_args: ccall_type list,
3905 :     ml_res_opt: ccall_type option,
3906 :     reentrant : bool
3907 :     } option
3908 :     (* Allocate uninitialized storage on the heap.
3909 :     * The record is meant to hold short-lived C objects, i.e., they
3910 : blume 2155 * are not ML pointers. With the tag, the representation is
3911 : leunga 1174 * the same as RECORD with tag tag_raw32 (sz=4), or tag_fblock (sz=8)
3912 :     *)
3913 : blume 2155 | RAW_RECORD of {tag:bool,sz:int}
3914 : leunga 1174 and ccall_type = CCALL_INT32 | CCALL_REAL64 | CCALL_ML_PTR
3915 :    
3916 :     2. These CPS primops are now overloaded:
3917 :    
3918 :     rawload of {kind:numkind}
3919 :     rawstore of {kind:numkind}
3920 :    
3921 :     The one argument form is:
3922 :    
3923 :     rawload {kind} address
3924 :    
3925 :     The two argument form is:
3926 : blume 2155
3927 : leunga 1174 rawload {kind} [ml object, byte-offset]
3928 :    
3929 :     3. RAW_CCALL/RCC now takes two extra arguments:
3930 :    
3931 :     a. The first is whether the C call is reentrant, i.e., whether
3932 :     ML state should be saved and restored.
3933 :     b. The second argument is a string argument specifying the name of
3934 :     library and the C function.
3935 :    
3936 :     These things are currently not handled in the code generator, yet.
3937 :    
3938 :     4. In CProto,
3939 :    
3940 : blume 2155 An encoding type of "bool" means "ml object" and is mapped into
3941 :     C prototype of PTR. Note that "bool" is different than "string",
3942 : leunga 1174 even though "string" is also mapped into PTR, because "bool"
3943 :     is assigned an CPS type of BOGt, while "string" is assigned INT32t.
3944 :    
3945 :     5. Pickler/unpicker
3946 :    
3947 :     Changed to handle RAW_RECORD and newest RAW_CCALL
3948 :    
3949 :     6. MLRiscGen,
3950 :    
3951 :     1. Changed to handle the new rawload/rawstore/rawrecord operators.
3952 :     2. Code for handling C Calls has been moved to a new module CPSCCalls,
3953 :     in the file CodeGen/cpscompile/cps-c-calls.sml
3954 :    
3955 :     7. Added the conditional move operator
3956 :    
3957 :     condmove of branch
3958 :    
3959 : blume 2155 to cps. Generation of this is still buggy so it is currently

3967 :    
3968 : blume 2155 Implemented the Ball-Larus branch prediction-heuristics, and
3969 : george 1168 incorporated graphical viewers for control flow graphs.
3970 :    
3971 : george 1171 Ball-Larus Heuristics:
3972 : george 1168 ---------------------
3973 :     See the file compiler/CodeGen/cpscompile/cpsBranchProb.sml.
3974 :    
3975 :     By design it uses the Dempster-Shafer theory for combining
3976 :     probabilities. For example, in the function:
3977 :    
3978 :     fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)
3979 :    
3980 :     the ball-larus heuristics predicts that the n=0 is unlikely
3981 :     (OH-heuristic), and the 'then' branch is unlikely because of the
3982 :     RH-heuristic -- giving the 'then' branch an even lower combined
3983 : george 1171 probability using the Dempster-Shafer theory.
3984 : george 1168
3985 :     Finally, John Reppy's loop analysis in MLRISC, further lowers the
3986 :     probability of the 'then' branch because of the loop in the else
3987 :     branch.
3988 :    
3989 :    
3990 :     Graphical Viewing:
3991 : blume 2155 ------------------
3992 : george 1168 I merely plugged in Allen's graphical viewers into the compiler. The
3993 :     additional code is not much. At the top level, saying:
3994 :    
3995 :     Control.MLRISC.getFlag "cfg-graphical-view" := true;
3996 :    
3997 :     will display the graphical view of the control flow graph just before
3998 :     back-patching. daVinci must be in your path for this to work. If
3999 :     daVinci is not available, then the default viewer can be changed
4000 :     using:
4001 :    
4002 :     Control.MLRISC.getString "viewer"
4003 :    
4004 :     which can be set to "dot" or "vcg" for the corresponding viewers. Of
4005 :     course, these viewers must be in your path.
4006 :    
4007 :     The above will display the compilation unit at the level of clusters,
4008 :     many of which are small, boring, and un-interesting. Also setting:
4009 :    
4010 :     Control.MLRISC.getInt "cfg-graphical-view_size"
4011 :    
4012 :     will display clusters that are larger than the value set by the above.

4037 :    
4038 : blume 2155 1. Recoded the buggy parts of x86-fp.
4039 : leunga 1156
4040 :     a. All the block reordering code has been removed.
4041 :     We now depend on the block placement phases to do this work.
4042 :    
4043 :     b. Critical edge splitting code has been simplified and moved into the
4044 :     CFG modules, as where they belong.
4045 :    
4046 :     Both of these were quite buggy and complex. The code is now much, much
4047 :     simpler.
4048 :    
4049 :     2. X86 backend.
4050 :    
4051 :     a. Added instructions for 64-bit support. Instruction selection for
4052 :     64-bit has not been committed, however, since that
4053 : blume 2155 requires changes to MLTREE which haven't been approved by
4054 : leunga 1156 Lal and John.
4055 :    
4056 : blume 2155 b. Added support for FUCOMI and FUCOMIP when generating code for
4057 : leunga 1156 PentiumPro and above. We only generate these instructions in
4058 :     the fast-fp mode.
4059 :    
4060 : blume 2155 c. Added cases for JP and JNP in X86FreqProps.
4061 :    
4062 : leunga 1156 3. CFG
4063 :    
4064 :     CFG now has a bunch of methods for edge splitting and merging.
4065 :    
4066 :     4. Machine description.
4067 :    
4068 :     John's simplification of MLTREE_BASIS.fcond broke a few machine
4069 :     description things:
4070 :    
4071 :     rtl-build.{sig,sml} and hppa.mdl fixed.
4072 :    
4073 : blume 2155 NOTE: the machine description stuff in the repository is still broken.

4101 :     The implementation of "convert" is based on the idea of "witness"
4102 :     values -- values that are not used by the operation but whose types
4103 :     "testify" to their applicability. On the implementation side, "convert"
4104 :     is simply a projection (returning its second curried argument). With
4105 :     cross-module inlining, it should not result in any machine code being
4106 :     generated.

4128 :     Description:
4129 :    
4130 :     Controls:
4131 :     ---------
4132 :    
4133 :     1. Factored out the recently-added Controls : CONTROLS stuff and put
4134 :     it into its own library $/controls-lib.cm. The source tree for
4135 :     this is under src/smlnj-lib/Controls.
4136 :    
4137 :     2. Changed the names of types and functions in this interface, so they
4138 :     make a bit more "sense":
4139 :    
4140 :     module -> registry
4141 :     'a registry -> 'a group
4142 :    
4143 :     3. The interface now deals in ref cells only. The getter/setter interface
4144 :     is (mostly) gone.
4145 :    
4146 :     4. Added a function that lets one register an already-existing ref cell.
4147 :    
4148 :     5. Made the corresponding modifications to the rest of the code so that
4149 :     everything compiles again.
4150 :    
4151 :     6. Changed the implementation of Controls.MLRISC back to something closer
4152 :     to the original. In particular, this module (and therefore MLRISC)
4153 :     does not depend on Controls. There now is some link-time code in
4154 :     int-sys.sml that registers the MLRISC controls with the Controls
4155 :     module.
4156 :    
4157 :     CM:
4158 :     ---
4159 :    
4160 :     * One can now specify the lambda-split aggressiveness in init.cmi.

4170 :     > leunga@weaselbane:~/Yale/tmp/sml-dist{21} bin/sml
4171 :     > Standard ML of New Jersey v110.39.1 [FLINT v1.5], March 08, 2002

4178 : leunga 1142 > uncaught exception Error
4179 :     > raised at: ../MLRISC/control/mlriscErrormsg.sml:16.14-16.19
4180 :    
4181 :     The problem was that the code generator did not generate any fp registers
4182 :     in this case, and the ra didn't know that it needed to run the X86FP phase to
4183 :     translate the pseudo fp instruction. This only happened with unary fp
4184 :     operators in certain situations.

4189 :     Tag: blume-20020313-overload-etc
4190 :     Description:
4191 :    
4192 :     1. Added _overload as a synonym for overload for backward compatibility.
4193 :     (Control.overloadKW must be true for either version to be accepted.)
4194 :    
4195 :     2. Fixed bug in install script that caused more things to be installed
4196 :     than what was requested in config/targets.
4197 :    
4198 :     3. Made CM aware of the (_)overload construct so that autoloading
4199 :     works.
