85 : blume 2692 Date: 2007/06/06 21:45:00 CDT
86 :     Description:
87 :    
88 :     - Aaron: fixed a number of bugs in ml-ulex.
89 :     - Matthias:
90 :     - added CM control "cm.force-tools"; this is false by default;
91 :     when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
92 :     will be forced to run regardless of whether or not their targets
93 :     are up-to-date
94 :     - changed installer code so that config/install.sh will re-build
95 :     heap images for all tools even if those heap images already existed
96 :    
97 :     ----------------------------------------------------------------------
98 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
99 : blume 2688 Date: 2007/06/04 21:21:00 CDT
100 :     Description:
101 :    
102 :     After Aaron Turon's bug fix for ml-ulex (handling the ^ character
103 :     in legacy mode), re-ran the lexer generator on all lex input files
104 :     and committed the results.
105 :    
106 :     This should fix the problem with ckit and nlffi that was reported
107 :     by Vesa A. Norrman.

118 : dbm 2650 Name: Dave MacQueen (dbm@cs.uchicago.edu)
119 :     Date: 2007/05/31 14:55:00 CDT
120 :     Revision: 2650
121 :     Description:
122 :    
123 :     3rd merge of base from primop-branch-3 into the trunk.
124 :     Additional bug fixes included:
125 :    
126 :     * Timer.cpu_timer, etc. type printing corrected (by making
127 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
128 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
129 :     Stefan Monnier)
130 :    
131 :     ----------------------------------------------------------------------
132 : blume 2645 Name: Matthias Blume (http://www.tti-c.org/blume/)
133 :     Date: 2007/05/31 11:40:00 CDT
134 :     Description:
135 :    
136 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
137 :    
138 :     Also, changed the handling of "no core access": When translate.sml
139 :     needs access to a core exception at a time when the core has not
140 :     been set up yet (this only happens when compiling system/smlnj/init/*),
141 :     then don't bother generating the corresponding tests.
142 :    
143 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
144 :     the exception. Unfortunately, that confuses the plambda type checker.
145 :     Moreover, it does not do any good, because at runtime we don't expect
146 :     such an exception to be ever raised. (The code in system/smlnj/init/*
147 :     has to be written very carefully with this in mind!)

150 : mrainey 2639 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
151 :     Date: 2007/05/29
152 :     Description:
153 :    
154 :     Added FSQRT instructions for the AMD64 code generator.
155 :    
156 :     ----------------------------------------------------------------------
157 : blume 2626 Name: Matthias Blume (http://www.tti-c.org/blume/)
158 :     Date: 2007/05/29 19:00:00 CDT
159 :     Description:
160 :    
161 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
162 :     with an explicit test for zero division. This should fixes several
163 :     regressions and makes it possible for downstream optimization phases
164 :     to treat these operations as "pure" when they are applied to unsigned
165 :     operands.
166 :    
167 :     ----------------------------------------------------------------------
168 : mrainey 2622 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
169 :     Date: 2007/05/29
170 :     Description:
171 :    
172 :     Added the new MLRISC code generator for the AMD64. This version,
173 :     in contrast to the previous one, uses SSE registers and instructions
174 :     for all floating-point computations.

177 : jhr 2613 Name: John Reppy (http://www.cs.uchicago.edu/~jhr)
178 : jhr 2617 Date: 2007/05/29
179 : jhr 2613 Description:
180 :    
181 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
182 :     for bugs #1415 and #1416. We also now correctly handle format characters that
183 :     lie outside the specified set.

186 : blume 2610 Name: Matthias Blume (http://www.tti-c.org/blume/)
187 :     Date: 2007/05/23 22:30:00 CDT
188 :     Description:
189 :    
190 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
191 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
192 :    
193 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
194 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
195 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
196 :     while running CMB.make. The point is that the single symbol
197 :     NO_PLUGINS is definde in all three cases.)
198 :    
199 :     I changed the three locations within the sources that get compiled
200 :     during CMB.make where ml-yacc or ml-lex input is processed: When
201 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
202 :     is bypassed.
203 :    
204 :     When bootstrapping new versions of the compiler, there can be
205 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
206 :     are not available or otherwise not operational. In this case one can
207 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
208 :     do so, the following command should be issued at the interactive
209 :     prompt:
210 :    
211 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
212 :    
213 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
214 :     files that normally would be generated by ml-yacc and ml-lex.
215 :     (Copies of these files are in the repository.)

218 : dbm 2603 Name: David MacQueen (dbm@cs.uchicago.edu)
219 :     Date: 2007/5/23 17:23:00 CDT
220 :     Revision: 2603
221 :     Description:
222 :    
223 :     2nd merge of base from primop-branch-3 into the trunk.
224 :     Additional bug fixes included:
225 :     Date.scan and Date.fromString fixed;
226 :     Overloading resolution fixed and some type printing problems corrected.

229 : blume 2578 Name: Matthias Blume (http://www.tti-c.org/blume/)
230 : blume 2589 Date: 2007/05/23 09:50:00 CDT
231 :     Description:
232 :    
233 :     Changed the installation mechanism for CM tool plugins. These are
234 :     just libaries and now get installed like ordinary libaries.
235 :    
236 :     There are now a number of new installation targets that give some
237 :     fine-grain control over what classes and suffixes are known, and what
238 :     they will map to.
239 :     See config/targets for details.
240 :    
241 :     The code that caused plugin installation as part of running a
242 :     tool's "build" script has been removed. (The build script is for
243 :     building, not for installing.)
244 :    
245 :     ----------------------------------------------------------------------
246 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
247 : blume 2578 Date: 2007/05/22 11:50:00 CDT
248 :     Description:
249 :    
250 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
251 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
252 :     CM fail if a shell tool reports a non-success exit status. If
253 :     the control is set to true, then CM will press on after tool failures
254 :     in the event that the target files exist (even though they are
255 :     considered outdated). Turning the control to true can be useful for
256 :     bootstrapping.

259 : adrassi 2570 Name: Aaron Turon (http://www.cs.uchicago.edu/~adrassi)
260 :     Date: 2007/05/19
261 :     Description:
262 :    
263 :     Merge of ml-lpt revisions for 110.64.
264 :    
265 :     The name of several ml-lpt-lib modules has changed:
266 :     Repair => AntlrRepair
267 :     StreamPos => AntlrStreamPos
268 :     ErrHandlerFn => AntlrErrHandler
269 :     EBNF => AntlrEBNF
270 :    
271 :     The ml-antlr specification format has changed: declarations such as
272 :     %tokens and nonterminal definitions can occur *multiple* times in the
273 :     same specification. The semantics are such that each new declaration
274 :     extends the previous ones. This does not apply to %start or %name,
275 :     of course.
276 :    
277 :     Importing a grammar via %import now includes *all* declarations in from
278 :     the imported grammar, except for %name, %entry, and %start. Tokens
279 :     and nonterminals can be dropped using the new %dropping clause of the
280 :     %import directive; the separate %drop and %extend have been removed.
281 :    
282 :     We now allow optional type annotations on nonterminals, using the %nonterms
283 :     directive as in ml-yacc.
284 :    
285 :     The refcell construct is now implemented using SML's regular reference
286 :     cells, so the :== and !! notation has been deprecated.
287 :    
288 :     The ml-antlr tool now does much more checking of specifications, and
289 :     its error messages have been greatly improved. Error repair for
290 :     generated parsers has been completely rewritten, and is now both
291 :     much faster and more accurate.
292 :    
293 :     ml-ulex is now more lenient with escape codes (non-SML-standard
294 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
295 :     Also, character classes may now include a "-" character at the beginning
296 :     as is standard in most other regexp tools.
297 :    
298 :     All of these changes are documented in the user guide, which has
299 :     been updated and improved with this merge.

305 :     Description:
306 :    
307 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
308 :     Significant changes in FLINT and the front end, mostly having to do
309 :     with a reorganized system for handling primops. Various bug fixes
310 :     and improvements in printing signatures.

315 :     Description:
316 :    
317 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
318 :     The ml-antlr specification format has changed: declarations such as
319 :     %tokens and nonterminal definitions can occur *multiple* times in the
320 :     same specification. The semantics are such that each new declaration
321 :     extends the previous ones. Grammar extension constructs have also
322 :     changed. We now allow type annotations on nonterminals. Finally,
323 :     the refcell construct is now implemented using SML's regular reference
324 :     cells, so the :== and !! notation has been deprecated. All of these
325 :     changes will appear in the 110.64 user guide for ml-lpt.
326 :    
327 :     The ml-antlr tool now does much more checking of specifications, and
328 :     its error messages have been greatly improved. There has also been
329 :     some work on the error repair process for generated parsers, but this
330 :     will be further improved in 110.64.

366 :     Description:
367 :    
368 :     More Basis fixes: The Char.fromString (etc.) functions did not handle

449 :     Date: 2007/02/26
450 :     Description:
451 :    
452 :     Added preliminary support in MLRISC for Staged Allocation, a technique
453 :     for specifying calling conventions (see
454 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
455 :     Initially, we plan to use this code to generate C calls for the AMD64.
456 :    
457 :     The staged allocation code base resides in MLRISC/staged-allocation,
458 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

463 :     Description:
464 :    
465 :     Bug fix: when SaveCState was called with two values to save, a subsequent
466 :     GC could cause the RestoreCState to fail because the saved state had been
467 :     promoted to tagless pair.

478 :    
479 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
480 :     of the range -128 ... 127. I've changed the code so that the range
481 :     check is disabled. Only the low order 8 bits of the immediate operand
482 : jhr 2342 are now significant.

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

523 :     Description:
524 :    
525 :     Brought ml-lpt manual up-to-date with the code. Many minor
526 :     improvements to the tools, and a few minor bugfixes. Prepared
527 :     ml-lpt-lib for integration with new UTF8 structure. Changed
528 :     the interface for creating streams in ml-ulex (we now support
529 :     stream creation from several kinds of sources). Overall, the
530 :     tools are now quite stable, and their interfaces are unlikely to
531 :     change in a way that would break compatibility. More work,
532 :     however, is needed in the documentation.

537 :     Description:
538 :    
539 :     Implemented library installer. Moved CM plugin code for
540 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
541 :     their respective trees. Implemented CM plugin for ml-ulex
542 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
543 :     and ml-antlr.
544 :    
545 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
546 :     CM tools. (It turns out to be too messy to do otherwise because
547 :     there is too much code that during installation relies on the presence
548 :     of these tools -- resulting in a tricky ordering problem.)

553 :     Description:
554 :    
555 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
556 :     Modified CM's startup code to use shiftArgs as it processes
557 :     command line arguments. This way, the init code in each .sml-file
558 :     or library that is mentioned at the top level will see only
559 :     those arguments that have not yet been processed at this point.
560 :     In other words, the init code can "seize control" and process the
561 :     remaining command line.

628 :     Description:
629 :    
630 :     Added code to CM's "standard shell tool" implementation which
631 :     causes it to tolerate (with a warning) the situation where the shell
632 :     command fails (e.g., due to the shell command's non-existence)
633 :     as long as all target files exist.
634 :    
635 :     This makes it possible to, e.g., build ml-yacc from sources even if
636 :     svn checkout messed up the time stamps on files in such a way that
637 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
638 :     be needed to re-process yacc.grm, but obviously it might not yet be
639 :     available at that time.)

645 :    
646 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
647 :     recvVecFromNB' in the SOCKET signature. This error is actually
648 :     in the SML Basis specification too.

677 : blume 2193 Date: 2006/11/09 14:30:00 CST
678 :     Tag: release-110.60
679 :     Description:
680 :    
681 :     New working release (110.60). NEW BOOTFILES!
682 :    
683 :     This is the first subversion-hosted release. There are also changes
684 :     to the directory layout. Here is a table:
685 :    
686 :     (All pathnames are relative to the SML/NJ "root" directory.)
687 :    
688 :     config -> config
689 :    
690 :     src/cm -> base/cm
691 :     src/compiler -> base/compiler
692 :     src/runtime -> base/runtime
693 :     src/system -> base/system
694 :    
695 :     src/cm/pgraph -> pgraph
696 :    
697 :     src/READMES -> base/READMES
698 :     src/$notefile -> base/NOTES/$notefile
699 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
700 :     MACOSXINSTALL WININSTALL
701 :    
702 :     src/smlnj-lib -> smlnj-lib
703 :     src/MLRISC -> MLRISC
704 :     ckit -> ckit
705 :     src/cml -> cml
706 :     src/eXene -> eXene
707 :     src/heap2asm -> heap2asm
708 :     src/lexgen -> lexgen
709 :     src/ml-burg -> ml-burg
710 :     src/ml-lex -> ml-lex
711 :     src/ml-yacc -> ml-yacc
712 :     src/ml-nlffi-lib -> nlffi/lib
713 :     src/ml-nlffigen -> nlffi/gen
714 :     src/smlnj-c -> smlnj-c
715 :     src/tools/TraceDebugProf -> trace-debug-profile
716 :    
717 :     In addition, there is also a new
718 :    
719 :     ml-lpt
720 :    
721 :     directory containing two new program generator tools: ml-ulex and
722 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
723 :     LL(k) parser generator). These tools are currently "beta-quality"
724 :    
725 :     The latest versios of the sources can now be obtained anonymously
726 :     via subversion. For this, it is useful to first check out
727 :    
728 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
729 :    
730 :     and put the resulting directory on your shell's PATH. This provides
731 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
732 :     and refresh-all.sh.
733 :    
734 :     To create a freshly checked-out copy of the sources, do
735 :    
736 :     checkout-all.sh [dir]
737 :    
738 :     where dir is the optional SML/NJ root directory (default is ".").
739 :    
740 :     This creates the above directory layout. Each subdirectory of
741 :     the root is under individual subversion control. The stat-all.sh
742 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
743 :     each of these subtrees.
744 :    
745 :     ----------------------------------------------------------------------
746 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
747 : blume 2155 Date: 2006/11/02 12:20:00 CST
748 :     Description:
749 :    
750 :     Reorganized directory layout.
751 :    
752 :     This is a temporary solution, more reorganization is to come.
753 :    
754 :     The basic idea is to have a number of toplevel trees, each corresponding
755 :     to a well-defined part of the overall system. Each part can be
756 :     maintained individually, even in separate source repositories,
757 :     although currently we still serve everything out of the main
758 :     smlnj-gforge tree.
759 :    
760 :     Installer and and scripts have been updated to reflect the new
761 :     layout. The installer (base/src/system/smlnj/installer) is now
762 :     "scriptable" to avoid burning too much knowledge about the
763 :     layout into SML source code. The main script used by the installer
764 :     is in config/actions.
765 :    
766 :     The main change is that many of the subdirectories of what used to
767 :     be known as "src" have moved to the toplevel. The "src" directory
768 :     itself has moved down into a subtree called "base". (We may eventually
769 :     get rid of the extra level of indirection represented by "src".)
770 :    
771 :     The layout is now as follows:
772 :    
773 :     toplevel tree name | default repository
774 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
775 :     -------------------+----------------------------------------------------
776 :     config | $gf/config/trunk
777 :     |
778 :     base | $gf/sml/trunk
779 :     |
780 :     smlnj-lib | $gf/smlnj-lib/trunk
781 :     MLRISC | $gf/MLRISC/trunk
782 :     |
783 :     ml-yacc | $gf/ml-yacc/trunk
784 :     ml-lex | $gf/ml-lex/trunk
785 :     ml-burg | $gf/ml-burg/trunk
786 :     lexgen | $gf/lexgen/trunk
787 :     heap2asm | $gf/heap2asm/trunk
788 :     |
789 :     cml | $gf/cml/trunk
790 :     eXene | $gf/eXene/trunk
791 :     ckit | $gf/ckit/trunk
792 :     nlffi | $gf/nlffi/trunk
793 :     |
794 :     smlnj-c | $gf/smlnj-c/trunk
795 :    
796 :     In $gf/admin there are a few useful shell scripts for checking out
797 :     and maintaining the entire collection of trees:
798 :    
799 :     admin/checkout-all.sh [dir]
800 :     -- optionally creates dir and checks out all trees from their
801 :     default repositories; if dir is missing, checkout into .
802 :     admin/refresh-all.sh [dir]
803 :     -- looks at all trees (from the above list) in dir (default: .)
804 :     and runs "svn update" if the tree exists and is under
805 :     subversion control;
806 :     non-existing or non-subversion trees are skipped
807 :     admin/stat-all.sh [dir]
808 :     -- like refresh-all.sh, but runs "svn stat" instead

954 :     Description:
955 :    
956 :     Hooked code for Darwin-specific Intel ABI into main compiler.
957 :     (This is a temporary solution which relies on the fact that the
958 :     compiler itself does not use NLFFI. Eventually we need to divorce
959 :     intel mac from generic x86 unix code and make separate sets of binaries.)

988 :     Description:
989 :    
990 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
991 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
992 : blume 2155 at the time when config/preloads is processed, the library has to
993 : mblume 1878 be referred to by another name. In 110.57 this would be
994 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
995 :     to be valid as well.)
996 :    
997 :     Thanks to Todd Wilson (Fresno) for alerting me to this issue.

1015 :     the physical location of basis.cm has changed). Also, corrected the

1050 :     Tag: blume-22051115-versiontool
1051 :     Description:
1052 :    
1053 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1054 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1055 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1056 :     it. Instead, it has the status of "user code", so it should use
1057 :     $/basis.cm to refer to the Basis library. (At least that's true for
1058 :     the purpose of bootstrapping the previous change. In the future it
1059 :     might make sense to have versiontool.cm refer to
1060 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1061 :     compiler itself uses.)
1062 :    
1063 :     Also patched src/system/testml to have it activate those extra anchor
1064 :     bindings in config/extrapathconfig.

1069 :     Tag: blume-22051115-libraries
1070 :     Description:
1071 :    
1072 :     This change affects the way the following libraries are tied into
1073 :     the system:
1074 :    
1075 :     $/basis.cm
1076 :     $/smlnj-lib.cm
1077 :     $/pp-lib.cm
1078 :     $/controls-lib.cm
1079 :     $/html-lib.cm
1080 :     $/ml-yacc-lib.cm
1081 :    
1082 :     These libraries are now internally (as seen from the source code
1083 :     of the implementation itself) known by the following names:
1084 :    
1085 :     $smlnj/basis/basis.cm
1086 :     $smlnj/smlnj-lib/smlnj-lib.cm
1087 :     $smlnj/smlnj-lib/pp-lib.cm
1088 :     $smlnj/smlnj-lib/controls-lib.cm
1089 :     $smlnj/smlnj-lib/html-lib.cm
1090 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1091 :    
1092 :     This makes it possible to work with code that requires different
1093 :     versions of these libraries, and which refers to these libraries using
1094 :     their "default" names (i.e., the first set of names above). In other
1095 :     words, one can un-define or re-define those default names without
1096 :     compromising the proper functioning of the compiler itself.
1097 :    
1098 :     A similar procedure had already been performed for several of the
1099 :     MLRISC libraries that are linked into the compiler. I did some
1100 :     cleanup on this code.
1101 :    
1102 :     A new file in the config directory (named extrapathconfig) is
1103 :     responsible for setting up path anchors that the compiler itself does
1104 :     not need, but that are typically required by user code.

1283 :     Tag: blume-20050516-redump-heap
1284 :     Description:
1285 :    
1286 :     Added mechanism for re-creating a heap file for the interactive system
1287 :     after configuration variables have been changed.
1288 :    
1289 :     CM.redump_heap : string -> unit
1290 :    
1291 :     This is much like SMLofNJ.exportML, but starting from the resulting
1292 : blume 2155 heap does not return to the caller of CM.redump_heap but
1293 : mblume 1792 restarts the interactive system from scratch. The original call of
1294 :     CM.redump_heap does not return but ends the interactive session.
1295 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1296 :    
1297 :     Internally, redump_heap winds the dynamic execution context back to
1298 :     the point where the original heap image was created and re-executes
1299 :     the heap image generation code in the boot code.

1305 :     Description:
1306 :    
1307 :     Added a hack to the existing hack known as Word64 to make fromString
1308 :     behave correctly. I am still not sure whether Word64.scan will work
1309 :     as specified with respect to the interaction of radix and prefix.

1415 :     Tag: blume-20050114-heap2exec
1416 :     Description:
1417 :    
1418 :     Implemented new (but still experimental) heap2exec facility. This is
1419 :     tested under Mac OS X and should work under Linux (will test shortly).
1420 :     It will probably also work on the Sparc (will test some time later).
1421 :    
1422 :     - removed old "HACKED_STANDALONE" hack from runtime
1423 :    
1424 :     To be able to test this, uncomment the request for "heap2asm" in
1425 :     config/targets prior to installation. (Notice that this is different
1426 :     from "heap2exec" mentioned below. Not a typo.)
1427 :    
1428 :     To perform an actual test, run the command
1429 :    
1430 :     $ bin/heap2exec heapfile execfile
1431 :    
1432 :     (You can put heap2exec on your shell's path.)
1433 :    
1434 :     For example, run
1435 :    
1436 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1437 :    
1438 :     This will create a standalone executable called "mly" which you can
1439 :     then invoke directly as a command.

1464 :     (The parameter-passing part of the picture has not complete. But
1465 :     data structure access seems to work.)
1466 :    
1467 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1468 :     (On the Mac, it is big-endian. And that's currently our only
1469 :     PPC platform.)

1584 :     Tag: blume-20041124-position
1585 :     Description:
1586 :    
1587 :     The compiler can now be compiled in a mode that makes structure Position
1588 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1589 :     for the time being.
1590 :    
1591 :     To enable 64-bit positions, use the following procedure:
1592 :    
1593 :     1. Start sml
1594 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1595 :     3. Type
1596 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1597 :     4. Run CMB.make() as usual.
1598 :    
1599 :     This is barely tested. The only test so far was a little SML program
1600 :     counting the number of characters in an 8-gigabyte file by
1601 :     reading it character-by-character. That test was successful.
1602 :    
1603 :     In support of 64-bit positions, a number of new functions have been
1604 :     added to the runtime system.

1649 :    
1650 :     - In a previous commit, fixed a minor issue with how polyequal is being
1651 :     translated. In particular, the code now "looks through" abstractions.
1652 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1653 :     more efficient code. Important examples for where this matters are
1654 :     the new int64 and word64 types.

1671 :     All the pieces of Word64 are now there, with the exception of the
1672 :     conversions from and to LargeWord. (Eventually these need to be identities,
1673 :     but for the time being they don't even make sense because LargeWord is
1674 :     32-bit wide.)
1675 :    
1676 :     Also started to add similar support for Int64, but major pieces of that
1677 :     are still missing.

1683 :     Description:
1684 :    
1685 :     Structure Word64 is now (almost) complete, word literals and patterns
1686 :     seem to work. There are a few odd pieces missing. In particular,
1687 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1688 :     at the moment.
1689 :    
1690 :     Making Word64 official would mean that LargeWord becomes Word64. But
1691 :     this requires extreme care because most word-word conversions have to
1692 :     go through LargeWord, so making a mistake means loss of efficiency or
1693 :     worse. Eventually there will be a solution similar to (but actually
1694 :     simpler than) what I did with IntInf.

1726 :     - Changend config/srcarchiveurl from a file just

1729 :     - Made corresponding changes to config/install.sh and config/unpack.
1730 :     - Default contents of config/srcarchiveurl uses $VERSION and
1731 :     normally does not have to be edited to reflect a version change.
1732 :    
1733 :     (As a result, a version change can be done by just editing
1734 :     config/version, the rest is now automatic.)

1774 :     Tag: blume-20041020-standalone-backtrace
1775 :     Description:
1776 :    
1777 :     Added a mechanism for getting back-trace information from standalone
1778 :     programs. Here is how it works:
1779 :    
1780 :     1. The part of the program from which you want to get backtrace
1781 :     information (usually the whole program) should be wrapped with
1782 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
1783 :     main program could be modified from something like
1784 :    
1785 :     fun main (pgm, args) = ...
1786 :    
1787 :     to
1788 :    
1789 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1790 :    
1791 :     2. To be able to access BackTrace.monitor, you have to add
1792 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
1793 :     main function.
1794 :    
1795 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1796 :     CM might have created in the past for your project).
1797 :    
1798 :     4. Build the system using this command line:
1799 :    
1800 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1801 :     myprog.cm MyProg.main myprog
1802 :    
1803 :     instead of the usual
1804 :    
1805 :     ml-build myprog.cm MyProg.main myprog
1806 :    
1807 :     I changed a library name:
1808 :    
1809 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1810 :    
1811 :     New libraries:
1812 :    
1813 :     $smlnj-tdp/back-trace.cm
1814 :     -- when loaded causes the back-trace plugin to be installed
1815 :     $smlnj-tdp/coverage.cm
1816 :     -- when loaded causes the coverage plugin to be installed

1832 :     Description:
1833 :    
1834 :     * Test coverage tool added!
1835 :     * Further reorganization of tracing-, debugging-, and profiling support:
1836 :    
1837 :     - moved original BTImp -- now called BackTrace -- into a separate
1838 :     library called $/trace-debug-profile.cm
1839 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
1840 :     - only the instrumentation mechanism is now left in the compiler proper
1841 :     - BackTrace module is a plugin which is NOT plugged in by default
1842 :     - Coverage module is another such plugin
1843 :    
1844 :     To get the benefits of any of these plugin modules, the code in
1845 :     question must be compiled with tdp instrumentation turned on. This
1846 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
1847 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1848 :    
1849 :     Plugins are selected at link time. (Pre-compiled instrumented code
1850 :     can be re-loaded with different plugins in effect.) When an
1851 :     instrumented module is linked, whatever plugins are at that time
1852 :     enabled will come into effect for that module.
1853 :    
1854 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
1855 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
1856 :     To enable the coverage plugin, load the same library and invoke
1857 :     Coverage.install().
1858 :    
1859 :     Back-traces are generated automatically on uncaught exceptions and
1860 :     when the code in question explicitly invokes BackTrace.trigger().
1861 :    
1862 :     Coverage (and execution frequency-) information must be queried
1863 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

1981 :     Description:
1982 :    
1983 :     Implemented some CM magic to have
1984 :     file src/compiler/TopLevel/main/version.sml
1985 :     generated automagically.
1986 :     The version is taken from two files: config/version and config/release.
1987 :     The first is expected to contain a two-part version number such as 110.49.
1988 :     The second should contain a single number, but it may be missing.
1989 :    
1990 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
1991 :     time the version tool is loaded (which is the first time you say CMB.make),
1992 :     then the tool will increment the value stored in config/release every
1993 :     time CMB.make is invoked.
1994 :    
1995 :     The binfile format is now insensitive to anything beyond the first
1996 :     two components of a version number, so bumping the release does not render
1997 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
1998 :     during development without invalidating existing binfiles.
1999 :    
2000 :     In any case, every CMB.make updates the date information in version.sml.

2014 :     Tag: blume-20040927-controls
2015 :     Description:
2016 :    
2017 :     Added two pieces of functionality to the Controls interface:
2018 :    
2019 :     1. val save'restore: 'a control -> unit -> unit
2020 :    
2021 :     grabs the current value of the control in stage 1 and restores it
2022 :     in stage 2.
2023 :    
2024 :     2. val set' : 'a control * 'a -> unit -> unit
2025 :    
2026 :     stores the given value into the control in stage 2 (i.e., delayed)
2027 :     but does all error checking in stage 1.
2028 :     (This is for string controls that need to do parse their argument --
2029 :     something that might fail. In some cases, notably in CM, one
2030 :     already knows the intended argument but wants to delay the actual
2031 :     assignment until a time when error recovery would be more difficult.)
2032 :    
2033 :     Changed the handling of controls in tool arguments to classes "sml" and
2034 :     "lazysml":
2035 :     - use Controls.save'restore as a more robust way of restoring the
2036 :     old value (in particular: without having to re-parse the string)
2037 :     - use controls to handle the "overload" keyword in the init group
2038 :     (I believe this change actually fixes a long-standing obscure bug.)

2043 :     Tag: blume-20040927-lazysml
2044 :     Description:
2045 :    
2046 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2047 :     difference to "sml" is that compilation is done with Control.lazysml
2048 :     set to true. A source of class "lazysml" is automatically recognized
2049 :     by a file name suffix of ".lml".
2050 :    
2051 :     In addition to the above feature, the original class "sml" now also
2052 :     supports a tool argument "lazy" which has the same effect. As a
2053 :     result, the following three lines are equivalent:
2054 :    
2055 :     foo.sml : lazysml
2056 :     foo.sml : sml (lazy)
2057 :     foo.sml (lazy)
2058 :    
2059 :     The setting goes into effect both during parsing and during
2060 :     compilation. The original setting is restored right after parsing and
2061 :     after compilation, respectively.
2062 :    
2063 :     In addition to all the above, there is also a general mechanism to set
2064 :     ANY of the "controls" that are available at the command line via
2065 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2066 :     apply as well. (In fact, "lazy" is implemented as a special case of
2067 :     the general mechanism.)
2068 :    
2069 :     The .cm file syntax uses a new keyword tool argument called "with".
2070 :     There are several ways of indicating the desired settings:
2071 :    
2072 :     foo.sml (with:parser.quotations=true)
2073 :     foo.sml (with:(name:parser.quotations value:true))
2074 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2075 :     foo.sml (with:(name1=value1 name2=value2 ...))
2076 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))

2439 :     Description:
2440 :    
2441 :     Changed the interface of structures Timer and Unix to match the most
2442 :     recent Basis spec.
2443 :    
2444 :     In the case of Unix there still seems to be an open/weird issue:
2445 :    
2446 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2447 :     fresh streams whenever they are called -- as opposed to have them
2448 :     return the same stream every time. This design is supposed to
2449 :     prevent space leaks caused by proc values hanging on to streams.
2450 :    
2451 :     The reap function, on the other hand, is supposed to close the
2452 :     streams. This cannot be done without having a handle on the
2453 :     stream in proc after all...
2454 :    
2455 :     I took the liberty to implement the following stopgap solution:
2456 :    
2457 :     The proc value hangs on to the most recently created stream(s).
2458 :     Reap closes those. If either or both of the two streams hadn't
2459 :     been created at all yet, then reap will close the corresponding
2460 :     file descriptors directly.
2461 :    
2462 :     PS: I don't understand the original space leak argument anymore. If
2463 :     a proc hangs on to the imperative stream, then I/O operations on those
2464 :     will advance the state of the cached stream and avoid the space leak.

2477 :     Tag: blume-20040525-group-owner
2478 :     Description:
2479 :    
2480 :     CM now ignores (but still accepts) the "owner" information in group
2481 :     descriptions. The owner of a group is its next enclosing
2482 :     library. Each group must have a unique owner. (There is a virtual
2483 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2484 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2485 :     and CM would check that such a declaration is correct. The new scheme
2486 :     is to have CM check that for each group there is precisely one owning
2487 :     library.
2488 :    
2489 :     The advantage of the new scheme is that the programmer no longer needs
2490 :     to maintain the somewhat annoying owner information. The downside is
2491 :     that CM cannot enforce the ownership rule across multiple runs of
2492 :     CM.make. Fortunately, enclosing the same group in two different
2493 :     libraries A and B which are not part of the same program does not
2494 :     cause real problems.

2500 :     Description:
2501 :    
2502 :     Made the win32 version work again. (Strangely, a misplaced comma had
2503 :     slipped into win32-process.c which prevented the runtime from being
2504 :     compiled correctly.)
2505 :    
2506 :     Also, included a minor addition to ml-build.bat analogous to what was
2507 :     done in blume-20040519-ml-build.

2512 :     Tag: blume-20040519-ml-build
2513 :     Description:
2514 :    
2515 :     Arranged for ml-build to clean up after itself a little bit better.
2516 :     The script generates a temporary SML source file and compiles it using
2517 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
2518 :     gets rid of those at the end, so they don't accumulate under .cm.
2519 :    
2520 :     This required a minor change to install.sh because the name of the
2521 :     metadata directory (default: .cm) is actually configurable at
2522 :     installation time.

2537 :     Description:
2538 :    
2539 :     Added previously missing support for many socket-related functions
2540 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
2541 :     for the voluminous patch!
2542 :    
2543 :     (I have not tested this patch under win32 yet.)
2544 :    
2545 : mblume 1490 Here is David's e-mail:
2546 :    
2547 :     Hi,
2548 :    
2549 :     Attached to this email you find a diff against sml/nj 110.45
2550 :     that will enable socket support under Windows.
2551 :    
2552 :     To apply the patch (using unix or cygwin)
2553 :     1) gunzip runtime.diff.gz
2554 :     2) "cd" into "src/runtime" in the source tree of a fresh
2555 :     110.45 installation.
2556 :     3) patch -p 1 < [your/path/to]runtime.diff
2557 :    
2558 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2559 :     I only ran a few tests for basic socket client functionality
2560 :     (which worked fine). Especially the functions that use ioctl
2561 : mblume 1490 are not tested at all and might not work (see below).
2562 :    
2563 :     I implemented this since we want to move to a newer version of sml/nj
2564 :     but need socket support in order to use it. This is the first time I
2565 :     even had a look at the sml/nj source, so please review my changes
2566 :     before making this part of the distribution! Here are a few issues
2567 : blume 2155 that I think might be better for someone to solve who is more
2568 : mblume 1490 familiar with the sml/nj source (and socket programming):
2569 :    
2570 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2571 :     exception since I could not figure out what the windows equivalent
2572 :     of these functions is
2573 :    
2574 :     - In sockets-osdep.h there are a some #include statements that are
2575 :     only used in a few files that include sockets-osdep.h
2576 :    
2577 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2578 :     does not process its return value since I don't know how to
2579 :     report an error upwards.
2580 :    
2581 :     - It would probably be good to have a call to WSACleanup() when
2582 : blume 2155 the library is unloaded (if there is such a possibility).
2583 : mblume 1490 Otherwise I think Windows will take care of this automatically
2584 :     when the process finishes.
2585 :    
2586 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2587 :     no idea if that is actually the proper replacement on Windows.
2588 :    
2589 :     - All these issues are marked in the code by "FIXME" comments.
2590 :    
2591 : blume 2155 We use sml/nj extensively in our products and are quite happy
2592 :     with it. I hope this contribution will help you.
2593 : mblume 1490
2594 :     Keep up the good work!

2675 :    
2676 :     lib = dlopen(NULL, ...)
2677 :     f = dlsym(lib, "malloc");
2678 :    
2679 : blume 2155 does not work on Windows unless we explicitly export symbols
2680 :     such as 'malloc' during linking. We fixed this by explicitly
2681 : allenleung 1468 exporting the required symbols with the magic gcc incantation:
2682 :    
2683 :     -Wl,--export-all cygwin.def
2684 :    
2685 :     where cygwin.def is a file containing all the symbols that
2686 : blume 2155 we wish to export.
2687 : allenleung 1468
2688 : blume 2155 I suspect this is a Windows problem and we'll have to
2689 :     do the same (somehow with windows compilers) when
2690 : allenleung 1468 we build the native win32 version with the system
2691 : blume 2155 calls LoadLibrary/GetProcAddress.

2817 :     Description:
2818 :    
2819 :     I modified the read-eval-print loop so that the autoloader gets
2820 :     invoked whenever the prettyprinter tries to look up a symbol that
2821 :     is not currently defined in the toplevel environment but which
2822 :     appears in CM's autoload registry. As a result, we see far fewer of
2823 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
2824 :    
2825 :     In addition to this I tried to clean up some pieces of the Basis
2826 :     implementation (e.g., Socket, Word8Array) in order to prevent other
2827 :     instances of these ?.Foo.Bar.xxx names from being printed.
2828 :    
2829 :     The mechanism that picks names for types still needs some work, though.
2830 :     (Right now it seems that if there is a type A.t which is defined to
2831 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
2832 :     "?.B.u" although the perhaps more sensible solution would be to use
2833 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
2834 :     a chain of DEFtycs not farther than there are corresponding toplevel
2835 :     names in the current environment.)

2841 :     Description:
2842 :    
2843 :     Another installer tweak: All the ML code for the installer is now
2844 :     compiled during CMB.make and put into a little library called
2845 :     $smlnj/installer.cm. The installation then simply invokes
2846 :    
2847 :     sml -m $smlnj/installer.cm
2848 :    
2849 :     and everything happens automagically.
2850 :    
2851 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
2852 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
2853 :     and BINDIR.
2854 :    
2855 :     The new scheme guarantees that the ML code responsible for the installation
2856 :     is in sync with the APIs of the main system. Also, the installer is
2857 :     somewhat faster because the installer script is precompiled.

2866 :     but excludes all non-blocking operations. Defined SOCKET (in Basis)
2867 :     and CML_SOCKET in terms of SYNCHRONOUS_SOCKET. Removed superfluous
2868 :     implementations of non-blocking operations from CML's Socket
2869 :     structure.

2875 :     Description:
2876 :    
2877 :     1. Fixed SOCKET API and implementation to match Basis spec.
2878 :     This required changing the internal representation of sockets to one
2879 :     that remembers (for each socket file descriptor) whether it is currently
2880 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
2881 :     call is made only if the state actually needs to change).
2882 :    
2883 :     2. OS-specific details of sockets were moved into separate files, thus
2884 :     making it possible to unify the bulk of the socket implementations
2885 :     between Unix and Win32.
2886 :    
2887 :     3. CML's socket API changed accordingly.
2888 :     (Note that we need to remove non-blocking functions from this API
2889 :     since they are redundant in the case of CML!)
2890 :    
2891 :     4. CML's socket implementation now makes use of non-blocking functions
2892 :     provided by Basis, thus removing all OS-dependent code from this part
2893 :     of CML.
2894 :    
2895 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

2941 :

3007 :     Tag: blume-20030909-installer
3008 :     Description:
3009 :    
3010 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3011 :     Modified config/install.bat to take advantage of it. Also modified
3012 :     config/install.sh (and called it config/new-install.sh) to take advantage
3013 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3014 :     independent.)
3015 :    
3016 :     The installer can now install everything under Win32
3017 :     as well as under *nix as long as it compiles.
3018 :    
3019 :     Other changes:
3020 :    
3021 :     - made CML compile again under Win32
3022 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3023 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3024 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3025 :     same as type int; under Win32 it isn't
3026 :     - fixed some slice-related problems in the win32-specific parts of CML
3027 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3028 :     (under Win32, the volume name is case-insensitive, and the
3029 :     OS.Path code compares volume names for equality)

3039 :     CM depends on it. (CM otherwise goes into an infinite loop in certain

3046 : mblume 1350 Description:
3047 :    
3048 :     1. Changed interface to vectors and arrays in Basis to match
3049 :     (draft) Basis spec.
3050 :     2. Added signatures and implementations of slices according to
3051 :     Basis spec.
3052 :     3. Edited source code throughout the system to make it compile again
3053 :     under 1. and 2. (In some cases code had to be added to have it
3054 :     match the new signatures.)
3055 :     4. MLRISC should be backward-compatible: the copies of the originals
3056 :     of files that needed to change under 3. were retained, the .cm files
3057 :     check the compiler version number and use old versions when
3058 :     appropriate.
3059 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3060 :     dirstream -> string option (in accordance with Basis spec).
3061 :     6. When generating code that counts lines, ml-lex used function
3062 :     CharVector.foldli, taking advantage of its old interface.
3063 :     This has been replaced with the corresponding code from
3064 :     CharVectorSlice. (html-lex must be re-lexed!)
3065 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3066 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3067 :     8. Removed temporary additions (fromInternal, toInternal) from the
3068 :     (now obsolete) IntInf in smlnj-lib/Util.
3069 :     9. Cleaned up structure Byte.
3070 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3071 :     Cleaned/corrected implementation of Date.
3072 :     (Still need to check for correctness; implement better canonicalizeDate.)
3073 :     11. Added "scan" to signature IEEE_REAL.
3074 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3075 :     mod and rem when second operand is 2 (for parity checks).]
3076 :     13. Changed representation of type Time.time, using a single IntInf.int
3077 :     value counting microseconds. This considerably simplified the
3078 :     implementation of structure Time. We now support negative time
3079 :     values; scan and fromString handle signs.
3080 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3081 :     ArraySlice).

3086 :     Tag: blume-20030828-intinf
3087 :     Description:
3088 :    
3089 :     This is a major update which comes with a version number bump
3090 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3091 :     and an implementation of IntInf in the Basis.
3092 :    
3093 :     There are a fairly large number of related changes and updates throughout
3094 :     the system:
3095 :    
3096 :     Basis:
3097 :     - Implemented IntInf.
3098 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3099 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3100 : mblume 1347 - Added FixedInt as a synonym for Int32.
3101 :    
3102 :     compiler:
3103 :     * Added support for a built-in intinf type.
3104 :     - literals
3105 :     - pattern matching
3106 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3107 :     - overloading on literals and operations
3108 :    
3109 :     This required adding a primitive type intinf, some additional
3110 :     primops, and implementations for several non-trivial intinf
3111 :     operations in Core. (The intinf type is completely abstract
3112 :     to the compiler; all operations get delegated back to the Core.)
3113 :    
3114 :     * Intinf equality is handled by polyequal. However, the compiler
3115 :     does not print its usual warning in this case (since polyequal
3116 :     is the right thing to do there).
3117 :    
3118 :     * Improved the organization of structure InlineT.
3119 :    
3120 :     * A word about conversion primops:
3121 :     If conversions involving intinf do not cancel out during
3122 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3123 : mblume 1347 Since all core access must be resolved already during the FLINT
3124 :     translate phase, it would be too late a the time of CPS contract
3125 : mblume 1348 to add new Core calls. For this reason, conversion primops
3126 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3127 :     they are supposed to convert, and 2. the Core function that
3128 :     can help with this conversion if necessary. If CPS contract
3129 : mblume 1348 eliminates a primop, then the associated Core function becomes
3130 :     dead and goes away. Intinf conversion primops that do not get
3131 :     eliminated by CPS contract get rewritten into calls of their
3132 :     core functions by a separate, new phase.
3133 : mblume 1347
3134 :     interactive system:
3135 :     - Control.Print.intinfDepth controls max length of intinf constants
3136 :     being printed. (Analogous to Control.Print.stringDepth.)
3137 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3138 :     duplicates; replaced some of the code with code that makes better
3139 :     use of library functionality.
3140 :    
3141 :     CM:
3142 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3143 :     are no longer silent.
3144 :    
3145 :     CKIT:
3146 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3147 :     in favor of LargeInt -- which is now the same as IntInf.
3148 :     CKIT-knowledgable people should check whether this is what's
3149 :     intended and otherwise change things back to using Int32 or
3150 :     FixedInt.
3151 :    
3152 :     Throughout the code:
3153 : mblume 1348 Started using IntInf.int literals and built-in operations
3154 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3173 :     Tag: blume-20030811-windows
3174 :     Description:
3175 :    
3176 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3177 :    
3178 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3179 :    
3180 :     This patch restores SML/NJ's ability to run under win32. There are a
3181 :     number of changes, including fixes for several bugs that had gone
3182 :     unnoticed until now:
3183 :    
3184 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3185 :     trying to run the win32 version from within cygwin.)
3186 :    
3187 :     - There are a number of simple .bat scripts that substitute for their
3188 :     corresponding Unix shell-scripts. (See below.)
3189 :    
3190 :     - The internals of ml-build have been modified slightly. The main
3191 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3192 :     using OS.Process.system, the ML process delegates this task back
3193 :     to the script. Otherwise problems arise in mixed environments such
3194 :     as Cygwin where scripts look and work like Unix scripts, but
3195 :     where OS.Process.system cannot run them.
3196 :    
3197 :     - In CM, the srcpath pickler used native pathname syntax -- which
3198 :     is incorrect in the case of cross-compilation. The new pickle format
3199 :     is independent of platform-specific naming conventions.
3200 :    
3201 :     - Path configuration files (such as lib/pathconfig) can now choose
3202 :     between native and standard syntax. Placing a line of the form
3203 :    
3204 :     standard!
3205 :    
3206 :     into the file causes all subsequent paths to be interpreted using
3207 :     CM standard pathname syntax (= Unix conventions); a line
3208 :    
3209 :     native!
3210 :    
3211 :     switches back to native style. This was needed so that
3212 :     path config files can be written portably, see src/system/pathconfig.
3213 :    
3214 :     - Runtime system:
3215 :    
3216 :     - win32-filesys.c: get_file_time and set_file_time now
3217 :     access modification time, not creation time.
3218 :    
3219 :     - I/O code made aware of new array representation.
3220 :    
3221 :     - Bug fixes in X86.prim.masm.
3222 :    
3223 :     - src/system/makeml made aware of win32. (For use under cygwin
3224 :     and other Unix-environments for windows.)
3225 :    
3226 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3227 :     which caused BinIO.inputAll to fail consistently.
3228 :    
3229 :     .bat scripts:
3230 :    
3231 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3232 :    
3233 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3234 :     applications (sml, ml-yacc, ml-lex).
3235 :     - ml-build.bat: analogous to ml-build.
3236 :     - config\install.bat: Analogous to config/install.sh. This requires
3237 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3238 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3239 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3240 :     and the bootfile hierarchy must have been unpacked under
3241 :     sml.boot.x86-win32.
3242 :     The script is very primitive and does a poor job at error checking.
3243 :     It only installs the base system, ml-lex, and ml-yacc. No other
3244 :     libraries are being installed (i.e., you get only those that
3245 :     are part of the compiler.)
3246 :     - link-sml.bat: analogous to .link-sml, but not currently used
3247 :    
3248 :     Unrelated bug fixes:
3249 :    
3250 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3251 :     types.
3252 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3253 :     otherwise.)

3261 :     Modified compiler/Elaborator/print/pptype.sml to fix bug 895.
3262 :     Tag will be used for new development branch (mcz-branch) for
3263 :     use by MacQueen, (Lucasz) Zairek, and (George) Cao at uchicago.

3269 :     Description:
3270 :

3276 :     Tag: blume-20030517-complete
3277 :     Description:
3278 :    
3279 :     Two changes:
3280 :    
3281 :     1. Added a flag for controlling whether non-exhaustive bindings will
3282 :     be treated as errors (default is false).
3283 :     2. Cleaned up the *entire* source tree so that CMB.make goes through
3284 :     without a single non-exhaustive match- or bind warning.

3289 :     Tag: blume-20030517-absyn
3290 :     Description:
3291 :    
3292 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3293 :    
3294 :     This mainly affects the quality of error messages. However, some
3295 :     of the code is now more straightforward than before. (Treatment of
3296 :     the above four constructs in translate.sml is much simpler than
3297 :     the "macro-expansion" that was going on before. Plus, the mach-
3298 :     compiler no longer gets invoked just to be able to compile an
3299 :     if-expression.)
3300 :    
3301 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3302 :     interactive loop.

3308 :     Description:
3309 :    
3310 : blume 2155 Ported the runtime system to cygwin, which uses the unix
3311 : allenleung 1327 x86-unix bin files. Missing/buggy features:
3312 :    
3313 : blume 2155 o getnetbyname, getnetbyaddr: these functions seem to be missing in
3314 : allenleung 1327 the Cygwin library.
3315 :     o Ctrl-C handling may be flaky.
3316 :     o Windows system calls and Windows I/O are not supported.
3317 :    
3318 :     A new set of binfiles is located at:
3319 :    
3320 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3321 :    
3322 :     This is only needed for bootstrapping the cygwin version of smlnj.
3323 :     Other x86 versions can use the existing binfiles.

3348 :     Description:

3350 :     Fixed a serious bug in the rewrite code for FP spilling/reloading that
3351 :     sent the RA into an infinite loop when floating point registers get
3352 :     spilled. (Because of this bug, e.g., nucleic stopped compiling between
3353 :     110.37 and 110.38.)
3354 :     There was another set of potential problems related to the handling of
3355 :     MLRISC annotations (but those did not yet cause real problems, apparently).

3361 :     Description:
3362 :    
3363 :     Added a call of SrcPath.sync at the beginning of Parse.parse (in CM).
3364 :     This fixes the problem of CM getting confused by files that suddenly
3365 :     change their identity (e.g., by getting unlinked and recreated by some
3366 :     text editor such as vi). There might be a better/cheaper/cleaner way

3382 :    
3383 : blume 1282 In good old tradition, there has been a slight hiccup so that we have
3384 :     to patch 110.42 after the fact. The old release tag has been replaced
3385 :     (see below).

3389 :     each other's way.
3390 :

3416 :     Description:
3417 :    
3418 :     Sml now senses the SMLNJ_HOME environment variable. If this is set,

3420 :     CM_PATHCONFIG is also set), the path configuration file is assumed

3422 :     the entire tree to some other place and everything will "just work".
3423 :

3478 :    
3479 :     Another small change is that ppDec tries to give more information
3480 :     than just "<sig>" in the case of functors. However, this code is
3481 :     broken in some mysterious way if the functor's body's signature
3482 :     has not been declared by ascription but gets inferred from the
3483 :     implementation. This needs fixing...

3550 :     registering MLRISC control ref cells with Controls after the fact)
3551 :     - Fixed messed-up controls priorities.
3552 :    
3553 :     * Removed again all the stuff from config/preloads that one wouldn't
3554 :     be able to preload at the time the initial heap image is built.
3555 :     (Many libraries, e.g., CML, do not exist yet at this time. The
3556 :     only libraries that can be preloaded via config/preloads are those
3557 :     that come bundled with the bootfiles.)

3582 :     Description:
3583 :    
3584 :     0. John Reppy made several modifications to the SML/NJ library.
3585 :     In particular, there is a shiny new controls-lib.cm.
3586 :    
3587 :     1. Pushed new controls interface through compiler so that everything
3588 :     compiles again.
3589 :    
3590 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3591 :     SML/NJ library (so that CML compiles again).
3592 :    
3593 :     3. Modified init scripts because XXX_DEFAULT environment variables
3594 :     are no longer with us. (Boot-time initialization is now done
3595 :     using the same environment variables that are also used for
3596 :     startup-time initialization of controls.)

3602 :     Description:
3603 :    
3604 :     All pseudo-ops emitted before the first segment declaration
3605 :     such as TEXT, DATA, and BSS directives are assumed to be global
3606 :     declarations and are emitted first in the assembly file. This is
3607 :     useful in a number of situations where one has pseudo-ops that are not
3608 :     specific to any segment, and also works around the constraint that one
3609 :     cannot have client pseudo-ops in the TEXT segment.
3610 :    
3611 :     Because no segment is associated with these declarations it is
3612 :     an error to allocate any space or objects before the first segment
3613 :     directive and an exception will be raised. However, we cannot make
3614 :     this check for client pseudo-ops.
3615 :    
3616 :     These top level declarations are a field in the CFG graph_info.
3617 :     In theory you can continue to add to this field after the CFG has been
3618 :     built -- provided you know what you are doing;-)

3641 :     Description:
3642 :    
3643 :     Applied the following bugfix provided by Emden Gansner:
3644 :    
3645 :     Output is corrupted when outputSubstr is used rather than output.
3646 :    
3647 : blume 2155 The problem occurs when a substring
3648 : blume 1189
3649 :     ss = (s, dataStart, dataLen)
3650 :    
3651 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3652 :     avail bytes of s, starting at index dataStart, are copied into the
3653 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3654 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3655 :     starting this copy at index dataStart+avail in s, the current code
3656 : blume 1189 starts the copy at index avail.
3657 :    
3658 :     Fix:
3659 :     In text-io-fn.sml, change line 695 from
3660 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3661 : blume 2155 to

3677 :     Tag: blume-20020401-x86div
3678 :     Description:
3679 :    
3680 :     Added full support for div/mod/rem/quot on the x86, using the machine
3681 :     instruction's two results (without clumsily recomputing the remainder)
3682 :     directly where appropriate.
3683 :    
3684 :     Some more extensive power-of-two support was added to the x86 instruction
3685 :     selector (avoiding expensive divs, mods, and muls where they can be
3686 :     replaced with cheaper shifts and masks). However, this sort of thing
3687 :     ought to be done earlier, e.g., within the CPS optimizer so that
3688 :     all architectures benefit from it.
3689 :    
3690 :     The compiler compiles to a fixed point, but changes might be somewhat
3691 :     fragile nevertheless. Please, report any strange things that you might
3692 :     see wrt. div/mod/quot/rem...

3697 :     Tag: blume-20020329-div
3698 :     Description:
3699 :    
3700 :     Fixed my broken div/mod logic. Unfortunately, this means that the
3701 :     inline code for div/mod now has one more comparison than before.
3702 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3703 :     The problem was with quotient = 0, because that alone does not tell
3704 :     us which way the rounding went. One then has to look at whether
3705 :     remainder and divisor have the same sign... :(
3706 :    
3707 :     Anyway, I replaced the bootfiles with fresh ones...

3713 :     Description:
3714 :    
3715 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
3716 :    
3717 :     Primops have changed. This means that the bin/boot-file formats have
3718 :     changed as well.
3719 :    
3720 :     To make sure that there is no confusion, I made a new version.
3721 :    
3722 :    
3723 :     CHANGES:
3724 :    
3725 :     * removed REMT from mltree (remainder should never overflow).
3726 :    
3727 :     * added primops to deal with divisions of all flavors to the frontend
3728 :    
3729 :     * handled these primops all the way through so they map to their respective
3730 :     MLRISC support
3731 :    
3732 :     * used these primops in the implementation of Int, Int32, Word, Word32
3733 :    
3734 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3735 :    
3736 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
3737 :    
3738 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3739 :     floating point
3740 :    
3741 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3742 :     and Real (but Real.abs maps to a separate floating-point-only primop)
3743 :    
3744 :    
3745 :     TODO items:
3746 :    
3747 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
3748 :     instructions because the machine instruction encoder cannot handle
3749 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
3750 :     REM in the first place, and REM is supported by the x86 machine coder.)
3751 :    
3752 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
3753 :     selection phase. (The two can be streamlined because the hardware
3754 :     delivers both quotient and remainder at the same time anyway.)
3755 :    
3756 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
3757 :     (Currently the behavior is inconsistent both across architectures and
3758 :     wrt. the draft Basis spec.)
3759 :    
3760 :     * Word8 should eventually be handled natively, too.
3761 :    
3762 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
3763 :     as if there currently is no execution path that could trigger it in
3764 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
3765 :     hold for things like multiplication and division.)

3770 :     Tag: blume-20020327-mlrisc-divisions
3771 :     Description:
3772 :    
3773 :     Added support for all four division operations (ML's div, mod, quot,
3774 :     and rem) to MLRISC. In the course of doing so, I also rationalized
3775 :     the naming (no more annoying switch-around of DIV and QUOT), by
3776 :     parameterizing the operation by div_rounding_mode (which can be either
3777 :     DIV_TO_ZERO or DIV_TO_NEGINF).
3778 :    
3779 :     The generic MLTreeGen functor takes care of compiling all four
3780 :     operations down to only round-to-zero div.
3781 :    
3782 :     Missing pieces:
3783 :    
3784 :     * Doing something smarter than relying on MLTreeGen on architectures
3785 :     like, e.g., the x86 where hardware division delivers both quotient and
3786 :     remainder at the same time. With this, the implementation of the
3787 :     round-to-neginf operations could be further streamlined.
3788 :    
3789 :     * Remove inlining support for div/mod/rem from the frontend and replace it
3790 :     with primops that get carried through to the backend. Do this for all
3791 :     int and word types.

3796 :     Tag: blume-20020325-divmod
3797 :     Description:
3798 :    
3799 :     I improved (hopefully without breaking them) the implementation of Int.div,
3800 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
3801 :     advantage of the following observations:
3802 :    
3803 :     Let q = x quot y r = x rem y
3804 :     d = x div y m = x mod y
3805 :    
3806 :     where "quot" is the round-to-zero version of integer division that
3807 :     hardware usually provides. Then we have:
3808 :    
3809 :     r = x - q * y where neither the * nor the - will overflow
3810 :     d = if q >= 0 orelse x = q * y then q else q - 1
3811 :     where neither the * nor the - will overflow
3812 :     m = if q >= 0 orelse r = 0 then r else r + y
3813 :     where the + will not overflow
3814 :    
3815 :     This results in substantial simplification of the generated code.
3816 :     The following table shows the number of CFG nodes and edges generated
3817 :     for
3818 :     fun f (x, y) = x OPER y
3819 :     (* with OPER \in div, mod, quot, rem *)
3820 :    
3821 :    
3822 :     OPER | nodes(old) | edges(old) | nodes(new) | edges(new)
3823 :     --------------------------------------------------------
3824 :     div | 24 | 39 | 12 | 16
3825 :     mod | 41 | 71 | 12 | 16
3826 :     quot | 8 | 10 | 8 | 10
3827 :     rem | 10 | 14 | 8 | 10

3860 :     Description:
3861 :    
3862 :     1. Changes to FLINT primops:
3863 :    
3864 :     (* make a call to a C-function;
3865 :     * The primop carries C function prototype information and specifies
3866 :     * which of its (ML-) arguments are floating point. C prototype
3867 :     * information is for use by the backend, ML information is for
3868 :     * use by the CPS converter. *)
3869 :     | RAW_CCALL of { c_proto: CTypes.c_proto,
3870 :     ml_args: ccall_type list,
3871 :     ml_res_opt: ccall_type option,
3872 :     reentrant : bool
3873 :     } option
3874 :     (* Allocate uninitialized storage on the heap.
3875 :     * The record is meant to hold short-lived C objects, i.e., they
3876 : blume 2155 * are not ML pointers. With the tag, the representation is
3877 : leunga 1174 * the same as RECORD with tag tag_raw32 (sz=4), or tag_fblock (sz=8)
3878 :     *)
3879 : blume 2155 | RAW_RECORD of {tag:bool,sz:int}
3880 : leunga 1174 and ccall_type = CCALL_INT32 | CCALL_REAL64 | CCALL_ML_PTR
3881 :    
3882 :     2. These CPS primops are now overloaded:
3883 :    
3884 :     rawload of {kind:numkind}
3885 :     rawstore of {kind:numkind}
3886 :    
3887 :     The one argument form is:
3888 :    
3889 :     rawload {kind} address
3890 :    
3891 :     The two argument form is:
3892 : blume 2155
3893 : leunga 1174 rawload {kind} [ml object, byte-offset]
3894 :    
3895 :     3. RAW_CCALL/RCC now takes two extra arguments:
3896 :    
3897 :     a. The first is whether the C call is reentrant, i.e., whether
3898 :     ML state should be saved and restored.
3899 :     b. The second argument is a string argument specifying the name of
3900 :     library and the C function.
3901 :    
3902 :     These things are currently not handled in the code generator, yet.
3903 :    
3904 :     4. In CProto,
3905 :    
3906 : blume 2155 An encoding type of "bool" means "ml object" and is mapped into
3907 :     C prototype of PTR. Note that "bool" is different than "string",
3908 : leunga 1174 even though "string" is also mapped into PTR, because "bool"
3909 :     is assigned an CPS type of BOGt, while "string" is assigned INT32t.
3910 :    
3911 :     5. Pickler/unpicker
3912 :    
3913 :     Changed to handle RAW_RECORD and newest RAW_CCALL
3914 :    
3915 :     6. MLRiscGen,
3916 :    
3917 :     1. Changed to handle the new rawload/rawstore/rawrecord operators.
3918 :     2. Code for handling C Calls has been moved to a new module CPSCCalls,
3919 :     in the file CodeGen/cpscompile/cps-c-calls.sml
3920 :    
3921 :     7. Added the conditional move operator
3922 :    
3923 :     condmove of branch
3924 :    
3925 : blume 2155 to cps. Generation of this is still buggy so it is currently
3926 : leunga 1174 disabled.

3932 : george 1168 Description:
3933 :    
3934 : blume 2155 Implemented the Ball-Larus branch prediction-heuristics, and
3935 : george 1168 incorporated graphical viewers for control flow graphs.
3936 :    
3937 : george 1171 Ball-Larus Heuristics:
3938 : george 1168 ---------------------
3939 :     See the file compiler/CodeGen/cpscompile/cpsBranchProb.sml.
3940 :    
3941 :     By design it uses the Dempster-Shafer theory for combining
3942 :     probabilities. For example, in the function:
3943 :    
3944 :     fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)
3945 :    
3946 :     the ball-larus heuristics predicts that the n=0 is unlikely
3947 :     (OH-heuristic), and the 'then' branch is unlikely because of the
3948 :     RH-heuristic -- giving the 'then' branch an even lower combined
3949 : george 1171 probability using the Dempster-Shafer theory.
3950 : george 1168
3951 :     Finally, John Reppy's loop analysis in MLRISC, further lowers the
3952 :     probability of the 'then' branch because of the loop in the else
3953 :     branch.
3954 :    
3955 :    
3956 :     Graphical Viewing:
3957 : blume 2155 ------------------
3958 : george 1168 I merely plugged in Allen's graphical viewers into the compiler. The
3959 :     additional code is not much. At the top level, saying:
3960 :    
3961 :     Control.MLRISC.getFlag "cfg-graphical-view" := true;
3962 :    
3963 :     will display the graphical view of the control flow graph just before
3964 :     back-patching. daVinci must be in your path for this to work. If
3965 :     daVinci is not available, then the default viewer can be changed
3966 :     using:
3967 :    
3968 :     Control.MLRISC.getString "viewer"
3969 :    
3970 :     which can be set to "dot" or "vcg" for the corresponding viewers. Of
3971 :     course, these viewers must be in your path.
3972 :    
3973 :     The above will display the compilation unit at the level of clusters,
3974 :     many of which are small, boring, and un-interesting. Also setting:
3975 :    
3976 :     Control.MLRISC.getInt "cfg-graphical-view_size"
3977 :    
3978 :     will display clusters that are larger than the value set by the above.

4002 :     Description:
4003 :    
4004 : blume 2155 1. Recoded the buggy parts of x86-fp.
4005 : leunga 1156
4006 :     a. All the block reordering code has been removed.
4007 :     We now depend on the block placement phases to do this work.
4008 :    
4009 :     b. Critical edge splitting code has been simplified and moved into the
4010 :     CFG modules, as where they belong.
4011 :    
4012 :     Both of these were quite buggy and complex. The code is now much, much
4013 :     simpler.
4014 :    
4015 :     2. X86 backend.
4016 :    
4017 :     a. Added instructions for 64-bit support. Instruction selection for
4018 :     64-bit has not been committed, however, since that
4019 : blume 2155 requires changes to MLTREE which haven't been approved by
4020 : leunga 1156 Lal and John.
4021 :    
4022 : blume 2155 b. Added support for FUCOMI and FUCOMIP when generating code for
4023 : leunga 1156 PentiumPro and above. We only generate these instructions in
4024 :     the fast-fp mode.
4025 :    
4026 : blume 2155 c. Added cases for JP and JNP in X86FreqProps.
4027 :    
4028 : leunga 1156 3. CFG
4029 :    
4030 :     CFG now has a bunch of methods for edge splitting and merging.
4031 :    
4032 :     4. Machine description.
4033 :    
4034 :     John's simplification of MLTREE_BASIS.fcond broke a few machine
4035 :     description things:
4036 :    
4037 :     rtl-build.{sig,sml} and hppa.mdl fixed.
4038 :    
4039 : blume 2155 NOTE: the machine description stuff in the repository is still broken.

4041 :     changes to MLTREE.

4063 :     This implements a generic mechanism for changing constness qualifiers
4064 :     anywhere within big C types without resorting to outright "casts".
4065 :     (So far, functions such as C.rw/C.ro or C.Ptr.rw/C.Ptr.ro only let you
4066 :     modify the constness at the outermost level.)
4067 :     The implementation of "convert" is based on the idea of "witness"

4103 :     2. Changed the names of types and functions in this interface, so they
4104 :     make a bit more "sense":
4105 :    
4106 :     module -> registry
4107 :     'a registry -> 'a group
4108 :    
4109 :     3. The interface now deals in ref cells only. The getter/setter interface
4110 :     is (mostly) gone.
4111 :    
4112 :     4. Added a function that lets one register an already-existing ref cell.
4113 :    
4114 :     5. Made the corresponding modifications to the rest of the code so that
4115 :     everything compiles again.
4116 :    
4117 :     6. Changed the implementation of Controls.MLRISC back to something closer
4118 :     to the original. In particular, this module (and therefore MLRISC)
4119 :     does not depend on Controls. There now is some link-time code in
4120 :     int-sys.sml that registers the MLRISC controls with the Controls
4121 :     module.
4122 :    
4123 :     CM:
4124 :     ---
4125 :    
4126 :     * One can now specify the lambda-split aggressiveness in init.cmi.

4145 :     > raised at: ../MLRISC/control/mlriscErrormsg.sml:16.14-16.19
4146 :    
4147 :     The problem was that the code generator did not generate any fp registers
4148 :     in this case, and the ra didn't know that it needed to run the X86FP phase to
4149 :     translate the pseudo fp instruction. This only happened with unary fp
4150 :     operators in certain situations.

4156 :     Description:
4157 :    
4158 :     1. Added _overload as a synonym for overload for backward compatibility.
4159 :     (Control.overloadKW must be true for either version to be accepted.)
4160 :    
4161 :     2. Fixed bug in install script that caused more things to be installed
4162 :     than what was requested in config/targets.
4163 :    
4164 :     3. Made CM aware of the (_)overload construct so that autoloading
4165 :     works.

4179 :     Description:
4180 :    
4181 :     Yet another version number bump (because of small changes to the
4182 :     binfile format). Version number is now 110.39.2. NEW BOOTFILES!
4183 :    
4184 :     Changes:
4185 :    
4186 :     The new pid generation scheme described a few weeks ago was overly
4187 :     complicated. I implemented a new mechanism that is simpler and
4188 :     provides a bit more "stability": Once CM has seen a compilation
4189 :     unit, it keeps its identity constant (as long as you do not delete
4190 :     those crucial CM/GUID/* files). This means that when you change
4191 : blume 1145 an interface, compile, then go back to the old interface, and
4192 : blume 1137 compile again, you arrive at the original pid.
4193 :    
4194 :     There now also is a mechanism that instructs CM to use the plain
4195 :     environment hash as a module's pid (effectively making its GUID
4196 :     the empty string). For this, "noguid" must be specified as an
4197 :     option to the .sml file in question within its .cm file.
4198 :     This is most useful for code that is being generated by tools such
4199 :     as ml-nlffigen (because during development programmers tend to
4200 :     erase the tool's entire output directory tree including CM's cached
4201 :     GUIDs). "noguid" is somewhat dangerous (since it can be used to locally
4202 :     revert to the old, broken behavior of SML/NJ, but in specific cases
4203 :     where there is no danger of interface confusion, its use is ok
4204 :     (I think).
