4 :     The entries in this file will be used when creating the README
5 :     for new versions, so keep that in mind when writing the
6 :     description.

18 :     Date: 2007/05/31 14:55:00 CDT
19 :     Revision: 2650
20 :     Description:
21 :    
22 :     3rd merge of base from primop-branch-3 into the trunk.
23 :     Additional bug fixes included:
24 :    
25 :     * Timer.cpu_timer, etc. type printing corrected (by making
26 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
27 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
28 :     Stefan Monnier)

31 : blume 2645 Name: Matthias Blume (http://www.tti-c.org/blume/)
32 :     Date: 2007/05/31 11:40:00 CDT
33 :     Description:
34 :    
35 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
36 :    
37 :     Also, changed the handling of "no core access": When translate.sml
38 :     needs access to a core exception at a time when the core has not
39 :     been set up yet (this only happens when compiling system/smlnj/init/*),
40 :     then don't bother generating the corresponding tests.
41 :    
42 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
43 :     the exception. Unfortunately, that confuses the plambda type checker.
44 :     Moreover, it does not do any good, because at runtime we don't expect
45 :     such an exception to be ever raised. (The code in system/smlnj/init/*
46 :     has to be written very carefully with this in mind!)

51 :     Description:
52 :    
53 :     Added FSQRT instructions for the AMD64 code generator.

56 : blume 2626 Name: Matthias Blume (http://www.tti-c.org/blume/)
57 :     Date: 2007/05/29 19:00:00 CDT
58 :     Description:
59 :    
60 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
61 :     with an explicit test for zero division. This should fixes several
62 :     regressions and makes it possible for downstream optimization phases
63 :     to treat these operations as "pure" when they are applied to unsigned
64 :     operands.

67 : mrainey 2622 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
68 :     Date: 2007/05/29
69 :     Description:
70 :    
71 :     Added the new MLRISC code generator for the AMD64. This version,
72 :     in contrast to the previous one, uses SSE registers and instructions
73 :     for all floating-point computations.

77 : jhr 2617 Date: 2007/05/29
78 : jhr 2613 Description:
79 :    
80 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
81 :     for bugs #1415 and #1416. We also now correctly handle format characters that
82 :     lie outside the specified set.

85 : blume 2610 Name: Matthias Blume (http://www.tti-c.org/blume/)
86 :     Date: 2007/05/23 22:30:00 CDT
87 :     Description:
88 :    
89 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
90 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
91 :    
92 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
93 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
94 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
95 :     while running CMB.make. The point is that the single symbol
96 :     NO_PLUGINS is definde in all three cases.)
97 :    
98 :     I changed the three locations within the sources that get compiled
99 :     during CMB.make where ml-yacc or ml-lex input is processed: When
100 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
101 :     is bypassed.
102 :    
103 :     When bootstrapping new versions of the compiler, there can be
104 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
105 :     are not available or otherwise not operational. In this case one can
106 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
107 :     do so, the following command should be issued at the interactive
108 :     prompt:
109 :    
110 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
111 :    
112 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
113 :     files that normally would be generated by ml-yacc and ml-lex.
114 :     (Copies of these files are in the repository.)

117 : dbm 2603 Name: David MacQueen (dbm@cs.uchicago.edu)
118 :     Date: 2007/5/23 17:23:00 CDT
119 :     Revision: 2603
120 :     Description:
121 :    
122 :     2nd merge of base from primop-branch-3 into the trunk.
123 :     Additional bug fixes included:
124 :     Date.scan and Date.fromString fixed;
125 :     Overloading resolution fixed and some type printing problems corrected.

128 : blume 2578 Name: Matthias Blume (http://www.tti-c.org/blume/)
129 : blume 2589 Date: 2007/05/23 09:50:00 CDT
130 :     Description:
131 :    
132 :     Changed the installation mechanism for CM tool plugins. These are
133 :     just libaries and now get installed like ordinary libaries.
134 :    
135 :     There are now a number of new installation targets that give some
136 :     fine-grain control over what classes and suffixes are known, and what
137 :     they will map to.
138 :     See config/targets for details.
139 :    
140 :     The code that caused plugin installation as part of running a
141 :     tool's "build" script has been removed. (The build script is for
142 :     building, not for installing.)
143 :    
144 :     ----------------------------------------------------------------------
145 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
146 : blume 2578 Date: 2007/05/22 11:50:00 CDT
147 :     Description:
148 :    
149 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
150 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
151 :     CM fail if a shell tool reports a non-success exit status. If
152 :     the control is set to true, then CM will press on after tool failures
153 :     in the event that the target files exist (even though they are
154 :     considered outdated). Turning the control to true can be useful for
155 :     bootstrapping.

159 :     Date: 2007/05/19
160 :     Description:
161 :    
162 :     Merge of ml-lpt revisions for 110.64.
163 :    
164 :     The name of several ml-lpt-lib modules has changed:
165 :     Repair => AntlrRepair
166 :     StreamPos => AntlrStreamPos
167 :     ErrHandlerFn => AntlrErrHandler
168 :     EBNF => AntlrEBNF
169 :    
170 :     The ml-antlr specification format has changed: declarations such as
171 :     %tokens and nonterminal definitions can occur *multiple* times in the
172 :     same specification. The semantics are such that each new declaration
173 :     extends the previous ones. This does not apply to %start or %name,
174 :     of course.
175 :    
176 :     Importing a grammar via %import now includes *all* declarations in from
177 :     the imported grammar, except for %name, %entry, and %start. Tokens
178 :     and nonterminals can be dropped using the new %dropping clause of the
179 :     %import directive; the separate %drop and %extend have been removed.
180 :    
181 :     We now allow optional type annotations on nonterminals, using the %nonterms
182 :     directive as in ml-yacc.
183 :    
184 :     The refcell construct is now implemented using SML's regular reference
185 :     cells, so the :== and !! notation has been deprecated.
186 :    
187 :     The ml-antlr tool now does much more checking of specifications, and
188 :     its error messages have been greatly improved. Error repair for
189 :     generated parsers has been completely rewritten, and is now both
190 :     much faster and more accurate.
191 :    
192 :     ml-ulex is now more lenient with escape codes (non-SML-standard
193 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
194 :     Also, character classes may now include a "-" character at the beginning
195 :     as is standard in most other regexp tools.
196 :    
197 :     All of these changes are documented in the user guide, which has
198 :     been updated and improved with this merge.

203 :     Revision: r2492
204 :     Description:
205 :    
206 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
207 :     Significant changes in FLINT and the front end, mostly having to do
208 :     with a reorganized system for handling primops. Various bug fixes
209 :     and improvements in printing signatures.

214 :     Description:
215 :    
216 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
217 :     The ml-antlr specification format has changed: declarations such as
218 :     %tokens and nonterminal definitions can occur *multiple* times in the
219 :     same specification. The semantics are such that each new declaration
220 :     extends the previous ones. Grammar extension constructs have also
221 :     changed. We now allow type annotations on nonterminals. Finally,
222 :     the refcell construct is now implemented using SML's regular reference
223 :     cells, so the :== and !! notation has been deprecated. All of these
224 :     changes will appear in the 110.64 user guide for ml-lpt.
225 :    
226 :     The ml-antlr tool now does much more checking of specifications, and
227 :     its error messages have been greatly improved. There has also been
228 :     some work on the error repair process for generated parsers, but this
229 :     will be further improved in 110.64.

265 :     Description:
266 :    
267 :     More Basis fixes: The Char.fromString (etc.) functions did not handle
268 :     the "\uxxxx" escape sequence. There is still an outstanding bug with
269 :     String.fromString the tail is a format escape. I added a comment to
270 :     this effect in Basis/Implementation/string.sml.

292 :    
293 : jhr 2444 More Basis fixes: the OS.Path module did not include the InvalidArc
294 :     exception and did not do sufficient argument checking.

307 :     Description:
308 :    
309 :     Substantially changed the signature and implementation of AMD64
310 :     SVID. It now looks similar to the ia32 SVID, yet uses staged
311 :     allocation.

347 : mrainey 2345 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
348 :     Date: 2007/02/26
349 :     Description:
350 :    
351 :     Added preliminary support in MLRISC for Staged Allocation, a technique
352 :     for specifying calling conventions (see
353 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
354 :     Initially, we plan to use this code to generate C calls for the AMD64.
355 :    
356 :     The staged allocation code base resides in MLRISC/staged-allocation,
357 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

362 :     Description:
363 :    
364 :     Bug fix: when SaveCState was called with two values to save, a subsequent
365 :     GC could cause the RestoreCState to fail because the saved state had been
366 :     promoted to tagless pair.

377 :    
378 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
379 :     of the range -128 ... 127. I've changed the code so that the range
380 :     check is disabled. Only the low order 8 bits of the immediate operand

421 :     Date: 2007/01/31
422 :     Description:
423 :    
424 :     Brought ml-lpt manual up-to-date with the code. Many minor
425 :     improvements to the tools, and a few minor bugfixes. Prepared
426 :     ml-lpt-lib for integration with new UTF8 structure. Changed
427 :     the interface for creating streams in ml-ulex (we now support
428 :     stream creation from several kinds of sources). Overall, the
429 :     tools are now quite stable, and their interfaces are unlikely to
430 :     change in a way that would break compatibility. More work,
431 :     however, is needed in the documentation.

436 :     Description:
437 :    
438 :     Implemented library installer. Moved CM plugin code for
439 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
440 :     their respective trees. Implemented CM plugin for ml-ulex
441 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
442 :     and ml-antlr.
443 :    
444 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
445 :     CM tools. (It turns out to be too messy to do otherwise because
446 :     there is too much code that during installation relies on the presence
447 :     of these tools -- resulting in a tricky ordering problem.)

452 :     Description:
453 :    
454 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
455 :     Modified CM's startup code to use shiftArgs as it processes
456 :     command line arguments. This way, the init code in each .sml-file
457 :     or library that is mentioned at the top level will see only
458 :     those arguments that have not yet been processed at this point.
459 :     In other words, the init code can "seize control" and process the
460 :     remaining command line.

517 :

527 :     Description:
528 :    
529 :     Added code to CM's "standard shell tool" implementation which
530 :     causes it to tolerate (with a warning) the situation where the shell
531 :     command fails (e.g., due to the shell command's non-existence)
532 :     as long as all target files exist.
533 :    
534 :     This makes it possible to, e.g., build ml-yacc from sources even if
535 :     svn checkout messed up the time stamps on files in such a way that
536 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
537 :     be needed to re-process yacc.grm, but obviously it might not yet be
538 :     available at that time.)

544 :    
545 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
546 :     recvVecFromNB' in the SOCKET signature. This error is actually
547 :     in the SML Basis specification too.

576 : blume 2193 Date: 2006/11/09 14:30:00 CST
577 :     Tag: release-110.60
578 :     Description:
579 :    
580 :     New working release (110.60). NEW BOOTFILES!
581 :    
582 :     This is the first subversion-hosted release. There are also changes
583 :     to the directory layout. Here is a table:
584 :    
585 :     (All pathnames are relative to the SML/NJ "root" directory.)
586 :    
587 :     config -> config
588 :    
589 :     src/cm -> base/cm
590 :     src/compiler -> base/compiler
591 :     src/runtime -> base/runtime
592 :     src/system -> base/system
593 :    
594 :     src/cm/pgraph -> pgraph
595 :    
596 :     src/READMES -> base/READMES
597 :     src/$notefile -> base/NOTES/$notefile
598 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
599 :     MACOSXINSTALL WININSTALL
600 :    
601 :     src/smlnj-lib -> smlnj-lib
602 :     src/MLRISC -> MLRISC
603 :     ckit -> ckit
604 :     src/cml -> cml
605 :     src/eXene -> eXene
606 :     src/heap2asm -> heap2asm
607 :     src/lexgen -> lexgen
608 :     src/ml-burg -> ml-burg
609 :     src/ml-lex -> ml-lex
610 :     src/ml-yacc -> ml-yacc
611 :     src/ml-nlffi-lib -> nlffi/lib
612 :     src/ml-nlffigen -> nlffi/gen
613 :     src/smlnj-c -> smlnj-c
614 :     src/tools/TraceDebugProf -> trace-debug-profile
615 :    
616 :     In addition, there is also a new
617 :    
618 :     ml-lpt
619 :    
620 :     directory containing two new program generator tools: ml-ulex and
621 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
622 :     LL(k) parser generator). These tools are currently "beta-quality"
623 :    
624 :     The latest versios of the sources can now be obtained anonymously
625 :     via subversion. For this, it is useful to first check out
626 :    
627 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
628 :    
629 :     and put the resulting directory on your shell's PATH. This provides
630 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
631 :     and refresh-all.sh.
632 :    
633 :     To create a freshly checked-out copy of the sources, do
634 :    
635 :     checkout-all.sh [dir]
636 :    
637 :     where dir is the optional SML/NJ root directory (default is ".").
638 :    
639 :     This creates the above directory layout. Each subdirectory of
640 :     the root is under individual subversion control. The stat-all.sh
641 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
642 :     each of these subtrees.
643 :    
644 :     ----------------------------------------------------------------------
645 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
646 : blume 2155 Date: 2006/11/02 12:20:00 CST
647 :     Description:
648 :    
649 :     Reorganized directory layout.
650 :    
651 :     This is a temporary solution, more reorganization is to come.
652 :    
653 :     The basic idea is to have a number of toplevel trees, each corresponding
654 :     to a well-defined part of the overall system. Each part can be
655 :     maintained individually, even in separate source repositories,
656 :     although currently we still serve everything out of the main
657 :     smlnj-gforge tree.
658 :    
659 :     Installer and and scripts have been updated to reflect the new
660 :     layout. The installer (base/src/system/smlnj/installer) is now
661 :     "scriptable" to avoid burning too much knowledge about the
662 :     layout into SML source code. The main script used by the installer
663 :     is in config/actions.
664 :    
665 :     The main change is that many of the subdirectories of what used to
666 :     be known as "src" have moved to the toplevel. The "src" directory
667 :     itself has moved down into a subtree called "base". (We may eventually
668 :     get rid of the extra level of indirection represented by "src".)
669 :    
670 :     The layout is now as follows:
671 :    
672 :     toplevel tree name | default repository
673 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
674 :     -------------------+----------------------------------------------------
675 :     config | $gf/config/trunk
676 :     |
677 :     base | $gf/sml/trunk
678 :     |
679 :     smlnj-lib | $gf/smlnj-lib/trunk
680 :     MLRISC | $gf/MLRISC/trunk
681 :     |
682 :     ml-yacc | $gf/ml-yacc/trunk
683 :     ml-lex | $gf/ml-lex/trunk
684 :     ml-burg | $gf/ml-burg/trunk
685 :     lexgen | $gf/lexgen/trunk
686 :     heap2asm | $gf/heap2asm/trunk
687 :     |
688 :     cml | $gf/cml/trunk
689 :     eXene | $gf/eXene/trunk
690 :     ckit | $gf/ckit/trunk
691 :     nlffi | $gf/nlffi/trunk
692 :     |
693 :     smlnj-c | $gf/smlnj-c/trunk
694 :    
695 :     In $gf/admin there are a few useful shell scripts for checking out
696 :     and maintaining the entire collection of trees:
697 :    
698 :     admin/checkout-all.sh [dir]
699 :     -- optionally creates dir and checks out all trees from their
700 :     default repositories; if dir is missing, checkout into .
701 :     admin/refresh-all.sh [dir]
702 :     -- looks at all trees (from the above list) in dir (default: .)
703 :     and runs "svn update" if the tree exists and is under
704 :     subversion control;
705 :     non-existing or non-subversion trees are skipped
706 :     admin/stat-all.sh [dir]
707 :     -- like refresh-all.sh, but runs "svn stat" instead

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

887 :     Description:
888 :    
889 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
890 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
891 : blume 2155 at the time when config/preloads is processed, the library has to
892 : mblume 1878 be referred to by another name. In 110.57 this would be
893 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
894 :     to be valid as well.)
895 :    
896 :     Thanks to Todd Wilson (Fresno) for alerting me to this issue.

949 :     Tag: blume-22051115-versiontool
950 :     Description:
951 :    
952 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
953 :     file gets loaded as a tool -- by the equivalent of CM.make during the
954 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
955 :     it. Instead, it has the status of "user code", so it should use
956 :     $/basis.cm to refer to the Basis library. (At least that's true for
957 :     the purpose of bootstrapping the previous change. In the future it
958 :     might make sense to have versiontool.cm refer to
959 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
960 :     compiler itself uses.)
961 :    
962 :     Also patched src/system/testml to have it activate those extra anchor
963 :     bindings in config/extrapathconfig.

968 :     Tag: blume-22051115-libraries
969 :     Description:
970 :    
971 :     This change affects the way the following libraries are tied into
972 :     the system:
973 :    
974 :     $/basis.cm
975 :     $/smlnj-lib.cm
976 :     $/pp-lib.cm
977 :     $/controls-lib.cm
978 :     $/html-lib.cm
979 :     $/ml-yacc-lib.cm
980 :    
981 :     These libraries are now internally (as seen from the source code
982 :     of the implementation itself) known by the following names:
983 :    
984 :     $smlnj/basis/basis.cm
985 :     $smlnj/smlnj-lib/smlnj-lib.cm
986 :     $smlnj/smlnj-lib/pp-lib.cm
987 :     $smlnj/smlnj-lib/controls-lib.cm
988 :     $smlnj/smlnj-lib/html-lib.cm
989 :     $smlnj/ml-yacc/ml-yacc-lib.cm
990 :    
991 :     This makes it possible to work with code that requires different
992 :     versions of these libraries, and which refers to these libraries using
993 :     their "default" names (i.e., the first set of names above). In other
994 :     words, one can un-define or re-define those default names without
995 :     compromising the proper functioning of the compiler itself.
996 :    
997 :     A similar procedure had already been performed for several of the
998 :     MLRISC libraries that are linked into the compiler. I did some
999 :     cleanup on this code.
1000 :    
1001 :     A new file in the config directory (named extrapathconfig) is
1002 :     responsible for setting up path anchors that the compiler itself does
1003 :     not need, but that are typically required by user code.

1183 :     Description:
1184 :    
1185 :     Added mechanism for re-creating a heap file for the interactive system
1186 :     after configuration variables have been changed.
1187 :    
1188 :     CM.redump_heap : string -> unit
1189 :    
1190 :     This is much like SMLofNJ.exportML, but starting from the resulting
1191 : blume 2155 heap does not return to the caller of CM.redump_heap but
1192 : mblume 1792 restarts the interactive system from scratch. The original call of
1193 :     CM.redump_heap does not return but ends the interactive session.
1194 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1195 :    
1196 :     Internally, redump_heap winds the dynamic execution context back to
1197 :     the point where the original heap image was created and re-executes
1198 :     the heap image generation code in the boot code.

1286 :     Description:
1287 :    
1288 :     Implemented "long long" arguments and results for NLFFI. (Only the
1289 :     PPC/MacOS implementation is complete, the other backends still need to
1290 :     be updated.)

1296 :     Description:
1297 :    
1298 :     Minor cleanup in ML-Yacc rule printing mechanism. This should fix a
1299 :     problem with certain "as" patterns which previously got rendered
1300 :     using incorrect syntax.

1314 :     Tag: blume-20050114-heap2exec
1315 :     Description:
1316 :    
1317 :     Implemented new (but still experimental) heap2exec facility. This is
1318 :     tested under Mac OS X and should work under Linux (will test shortly).
1319 :     It will probably also work on the Sparc (will test some time later).
1320 :    
1321 :     - removed old "HACKED_STANDALONE" hack from runtime
1322 :    
1323 :     To be able to test this, uncomment the request for "heap2asm" in
1324 :     config/targets prior to installation. (Notice that this is different
1325 :     from "heap2exec" mentioned below. Not a typo.)
1326 :    
1327 :     To perform an actual test, run the command
1328 :    
1329 :     $ bin/heap2exec heapfile execfile
1330 :    
1331 :     (You can put heap2exec on your shell's path.)
1332 :    
1333 :     For example, run
1334 :    
1335 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1336 :    
1337 :     This will create a standalone executable called "mly" which you can
1338 :     then invoke directly as a command.

1363 :     (The parameter-passing part of the picture has not complete. But
1364 :     data structure access seems to work.)
1365 :    
1366 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1367 :     (On the Mac, it is big-endian. And that's currently our only
1368 :     PPC platform.)

1438 :     is likely still full of bugs and inherently incomplete. (We need to

1483 :     Tag: blume-20041124-position
1484 :     Description:
1485 :    
1486 :     The compiler can now be compiled in a mode that makes structure Position
1487 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1488 :     for the time being.
1489 :    
1490 :     To enable 64-bit positions, use the following procedure:
1491 :    
1492 :     1. Start sml
1493 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1494 :     3. Type
1495 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1496 :     4. Run CMB.make() as usual.
1497 :    
1498 :     This is barely tested. The only test so far was a little SML program
1499 :     counting the number of characters in an 8-gigabyte file by
1500 :     reading it character-by-character. That test was successful.
1501 :    
1502 :     In support of 64-bit positions, a number of new functions have been
1503 :     added to the runtime system.

1547 :     The date string is generated at bootstrap time (during makeml).
1548 :    
1549 :     - In a previous commit, fixed a minor issue with how polyequal is being
1550 :     translated. In particular, the code now "looks through" abstractions.
1551 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1552 :     more efficient code. Important examples for where this matters are
1553 :     the new int64 and word64 types.

1568 :     Description:
1569 :    
1570 :     All the pieces of Word64 are now there, with the exception of the
1571 :     conversions from and to LargeWord. (Eventually these need to be identities,
1572 :     but for the time being they don't even make sense because LargeWord is
1573 :     32-bit wide.)
1574 :    
1575 :     Also started to add similar support for Int64, but major pieces of that
1576 :     are still missing.

1582 :     Description:
1583 :    
1584 :     Structure Word64 is now (almost) complete, word literals and patterns
1585 :     seem to work. There are a few odd pieces missing. In particular,
1586 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1587 :     at the moment.
1588 :    
1589 :     Making Word64 official would mean that LargeWord becomes Word64. But
1590 :     this requires extreme care because most word-word conversions have to
1591 :     go through LargeWord, so making a mistake means loss of efficiency or
1592 :     worse. Eventually there will be a solution similar to (but actually
1593 :     simpler than) what I did with IntInf.

1628 :     - Made corresponding changes to config/install.sh and config/unpack.
1629 :     - Default contents of config/srcarchiveurl uses $VERSION and
1630 :     normally does not have to be edited to reflect a version change.
1631 :    
1632 :     (As a result, a version change can be done by just editing
1633 :     config/version, the rest is now automatic.)

1656 :     (the callee already pops the implicit argument which points to

1673 :     Tag: blume-20041020-standalone-backtrace
1674 :     Description:
1675 :    
1676 :     Added a mechanism for getting back-trace information from standalone
1677 :     programs. Here is how it works:
1678 :    
1679 :     1. The part of the program from which you want to get backtrace
1680 :     information (usually the whole program) should be wrapped with
1681 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
1682 :     main program could be modified from something like
1683 :    
1684 :     fun main (pgm, args) = ...
1685 :    
1686 :     to
1687 :    
1688 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1689 :    
1690 :     2. To be able to access BackTrace.monitor, you have to add
1691 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
1692 :     main function.
1693 :    
1694 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1695 :     CM might have created in the past for your project).
1696 :    
1697 :     4. Build the system using this command line:
1698 :    
1699 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1700 :     myprog.cm MyProg.main myprog
1701 :    
1702 :     instead of the usual
1703 :    
1704 :     ml-build myprog.cm MyProg.main myprog
1705 :    
1706 :     I changed a library name:
1707 :    
1708 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1709 :    
1710 :     New libraries:
1711 :    
1712 :     $smlnj-tdp/back-trace.cm
1713 :     -- when loaded causes the back-trace plugin to be installed
1714 :     $smlnj-tdp/coverage.cm
1715 :     -- when loaded causes the coverage plugin to be installed

1731 :     Description:
1732 :    
1733 :     * Test coverage tool added!
1734 :     * Further reorganization of tracing-, debugging-, and profiling support:
1735 :    
1736 :     - moved original BTImp -- now called BackTrace -- into a separate
1737 :     library called $/trace-debug-profile.cm
1738 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
1739 :     - only the instrumentation mechanism is now left in the compiler proper
1740 :     - BackTrace module is a plugin which is NOT plugged in by default
1741 :     - Coverage module is another such plugin
1742 :    
1743 :     To get the benefits of any of these plugin modules, the code in
1744 :     question must be compiled with tdp instrumentation turned on. This
1745 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
1746 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1747 :    
1748 :     Plugins are selected at link time. (Pre-compiled instrumented code
1749 :     can be re-loaded with different plugins in effect.) When an
1750 :     instrumented module is linked, whatever plugins are at that time
1751 :     enabled will come into effect for that module.
1752 :    
1753 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
1754 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
1755 :     To enable the coverage plugin, load the same library and invoke
1756 :     Coverage.install().
1757 :    
1758 :     Back-traces are generated automatically on uncaught exceptions and
1759 :     when the code in question explicitly invokes BackTrace.trigger().
1760 :    
1761 :     Coverage (and execution frequency-) information must be queried
1762 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

1777 :     Description:
1778 :    
1779 :     Some rationalization of names:
1780 :    
1781 :     structure BTrace -> structure TDPInstrument
1782 :     etc.
1783 :    
1784 :     This is is preparation of using the original back-trace
1785 :     instrumentation for other purposes. "TDP" stands for
1786 :     Trace/Debug/Profile.
1787 :    
1788 :     The control flag controlling whether instrumentation is on or off is now
1789 :     registered under a different name, so instead of running sml as
1790 :    
1791 :     sml -Cinstrument.btrace-mode=true
1792 :

1805 :     regions being reported in error- and debug messages.

1811 :     Description:
1812 :    
1813 :     Fixed handling of keywords in .cm files: After seeing "is" the lexer
1814 :     treats subsequent occurrences of "group", "library", "source", "is",
1815 :     "*", and "-" as ordinary identifiers rather than keywords.
1816 :    
1817 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool
1818 :     is supposed to accept a tool argument called "source", but this did
1819 :     not work because of the clash with the keyword.

1830 :     hash table implementation
1831 :     - threw out most of the pathnames stuff, as it was not used anyway
1832 :     - simplified tokentable implementation

1851 :     Description:

1853 :     Added hack to make slave mode work in the presence of the version
1854 :     tool. (Still, since the master does two passes over the code for
1855 :     CMB.make, the release number gets bumped twice when slaves are
1856 :     attached. I don't know if this is worth fixing...)

1862 :     Description:
1863 :    
1864 :     * Moved the "version" magic into its own little library under
1865 : mblume 1672 src/system/smlnj/internal. This avoids expensive reconstruction of
1866 :     a stable src/compiler/core.cm.
1867 : mblume 1639
1868 : mblume 1672 * At the same time, structure CompilerVersion is now known as
1869 :     structure SMLNJVersion.
1870 : mblume 1639
1871 :     * Arranged for the version tool to NOT kick in when rebuilding the system
1872 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
1873 :     Also, loading the versiontool does not work when rebuilding the system
1874 :     because CM is not properly initialized at that time.

1879 :     Tag: blume-20040929-autoversion
1880 :     Description:
1881 :    
1882 :     Implemented some CM magic to have
1883 :     file src/compiler/TopLevel/main/version.sml
1884 :     generated automagically.
1885 :     The version is taken from two files: config/version and config/release.
1886 :     The first is expected to contain a two-part version number such as 110.49.
1887 :     The second should contain a single number, but it may be missing.
1888 :    
1889 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
1890 :     time the version tool is loaded (which is the first time you say CMB.make),
1891 :     then the tool will increment the value stored in config/release every
1892 :     time CMB.make is invoked.
1893 :    
1894 :     The binfile format is now insensitive to anything beyond the first
1895 :     two components of a version number, so bumping the release does not render
1896 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
1897 :     during development without invalidating existing binfiles.
1898 :    
1899 :     In any case, every CMB.make updates the date information in version.sml.
1900 :     (This is the date that is printed in the banner.)

1913 :     Tag: blume-20040927-controls
1914 :     Description:
1915 :    
1916 :     Added two pieces of functionality to the Controls interface:
1917 :    
1918 :     1. val save'restore: 'a control -> unit -> unit
1919 :    
1920 :     grabs the current value of the control in stage 1 and restores it
1921 :     in stage 2.
1922 :    
1923 :     2. val set' : 'a control * 'a -> unit -> unit
1924 :    
1925 :     stores the given value into the control in stage 2 (i.e., delayed)
1926 :     but does all error checking in stage 1.
1927 :     (This is for string controls that need to do parse their argument --
1928 :     something that might fail. In some cases, notably in CM, one
1929 :     already knows the intended argument but wants to delay the actual
1930 :     assignment until a time when error recovery would be more difficult.)
1931 :    
1932 :     Changed the handling of controls in tool arguments to classes "sml" and
1933 :     "lazysml":
1934 :     - use Controls.save'restore as a more robust way of restoring the
1935 :     old value (in particular: without having to re-parse the string)
1936 :     - use controls to handle the "overload" keyword in the init group
1937 :     (I believe this change actually fixes a long-standing obscure bug.)

1942 :     Tag: blume-20040927-lazysml
1943 :     Description:
1944 :    
1945 :     Added a new tool class called "lazysml" to CM's tool chest. The only
1946 :     difference to "sml" is that compilation is done with Control.lazysml
1947 :     set to true. A source of class "lazysml" is automatically recognized
1948 :     by a file name suffix of ".lml".
1949 :    
1950 :     In addition to the above feature, the original class "sml" now also
1951 :     supports a tool argument "lazy" which has the same effect. As a
1952 :     result, the following three lines are equivalent:
1953 :    
1954 :     foo.sml : lazysml
1955 :     foo.sml : sml (lazy)
1956 :     foo.sml (lazy)
1957 :    
1958 :     The setting goes into effect both during parsing and during
1959 :     compilation. The original setting is restored right after parsing and
1960 :     after compilation, respectively.
1961 :    
1962 :     In addition to all the above, there is also a general mechanism to set
1963 :     ANY of the "controls" that are available at the command line via
1964 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
1965 :     apply as well. (In fact, "lazy" is implemented as a special case of
1966 :     the general mechanism.)
1967 :    
1968 :     The .cm file syntax uses a new keyword tool argument called "with".
1969 :     There are several ways of indicating the desired settings:
1970 :    
1971 :     foo.sml (with:parser.quotations=true)
1972 :     foo.sml (with:(name:parser.quotations value:true))
1973 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
1974 :     foo.sml (with:(name1=value1 name2=value2 ...))
1975 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
1976 :    
1977 :     etc.
1978 :    
1979 :     Another possible abbreviation is to leave out the =v or value:v part
1980 :     if the name refers to a boolean control (in which case the value is
1981 :     taken to be true). Thus, one could get lazy sml also by saying:
1982 :    
1983 :     foo.sml (with:parser.lazy-keyword=true)
1984 :     foo.sml (with:parser.lazy-keyword)
1985 :     foo.sml (with:(name:parser.lazy-keyword value:true))
1986 :     foo.sml (with:(name:parser.lazy-keyword))

2338 :     Description:
2339 :    
2340 :     Changed the interface of structures Timer and Unix to match the most
2341 :     recent Basis spec.
2342 :    
2343 :     In the case of Unix there still seems to be an open/weird issue:
2344 :    
2345 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2346 :     fresh streams whenever they are called -- as opposed to have them
2347 :     return the same stream every time. This design is supposed to
2348 :     prevent space leaks caused by proc values hanging on to streams.
2349 :    
2350 :     The reap function, on the other hand, is supposed to close the
2351 :     streams. This cannot be done without having a handle on the
2352 :     stream in proc after all...
2353 :    
2354 :     I took the liberty to implement the following stopgap solution:
2355 :    
2356 :     The proc value hangs on to the most recently created stream(s).
2357 :     Reap closes those. If either or both of the two streams hadn't
2358 :     been created at all yet, then reap will close the corresponding
2359 :     file descriptors directly.
2360 :    
2361 :     PS: I don't understand the original space leak argument anymore. If
2362 :     a proc hangs on to the imperative stream, then I/O operations on those
2363 :     will advance the state of the cached stream and avoid the space leak.

2376 :     Tag: blume-20040525-group-owner
2377 :     Description:
2378 :    
2379 :     CM now ignores (but still accepts) the "owner" information in group
2380 :     descriptions. The owner of a group is its next enclosing
2381 :     library. Each group must have a unique owner. (There is a virtual
2382 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2383 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2384 :     and CM would check that such a declaration is correct. The new scheme
2385 :     is to have CM check that for each group there is precisely one owning
2386 :     library.
2387 :    
2388 :     The advantage of the new scheme is that the programmer no longer needs
2389 :     to maintain the somewhat annoying owner information. The downside is
2390 :     that CM cannot enforce the ownership rule across multiple runs of
2391 :     CM.make. Fortunately, enclosing the same group in two different
2392 :     libraries A and B which are not part of the same program does not
2393 :     cause real problems.

2417 :     gets rid of those at the end, so they don't accumulate under .cm.

2443 :    
2444 : mblume 1490 Here is David's e-mail:
2445 :    
2446 :     Hi,
2447 :    
2448 :     Attached to this email you find a diff against sml/nj 110.45
2449 :     that will enable socket support under Windows.
2450 :    
2451 :     To apply the patch (using unix or cygwin)
2452 :     1) gunzip runtime.diff.gz
2453 :     2) "cd" into "src/runtime" in the source tree of a fresh
2454 :     110.45 installation.
2455 :     3) patch -p 1 < [your/path/to]runtime.diff
2456 :    
2457 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2458 :     I only ran a few tests for basic socket client functionality
2459 :     (which worked fine). Especially the functions that use ioctl
2460 : mblume 1490 are not tested at all and might not work (see below).
2461 :    
2462 :     I implemented this since we want to move to a newer version of sml/nj
2463 :     but need socket support in order to use it. This is the first time I
2464 :     even had a look at the sml/nj source, so please review my changes
2465 :     before making this part of the distribution! Here are a few issues
2466 : blume 2155 that I think might be better for someone to solve who is more
2467 : mblume 1490 familiar with the sml/nj source (and socket programming):
2468 :    
2469 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2470 :     exception since I could not figure out what the windows equivalent
2471 :     of these functions is
2472 :    
2473 :     - In sockets-osdep.h there are a some #include statements that are
2474 :     only used in a few files that include sockets-osdep.h
2475 :    
2476 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2477 :     does not process its return value since I don't know how to
2478 :     report an error upwards.
2479 :    
2480 :     - It would probably be good to have a call to WSACleanup() when
2481 : blume 2155 the library is unloaded (if there is such a possibility).
2482 : mblume 1490 Otherwise I think Windows will take care of this automatically
2483 :     when the process finishes.
2484 :    
2485 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2486 :     no idea if that is actually the proper replacement on Windows.
2487 :    
2488 :     - All these issues are marked in the code by "FIXME" comments.
2489 :    
2490 : blume 2155 We use sml/nj extensively in our products and are quite happy
2491 :     with it. I hope this contribution will help you.

2577 :    
2578 : blume 2155 does not work on Windows unless we explicitly export symbols
2579 :     such as 'malloc' during linking. We fixed this by explicitly

2587 : blume 2155 I suspect this is a Windows problem and we'll have to

2716 :     Description:
2717 :    
2718 :     I modified the read-eval-print loop so that the autoloader gets
2719 :     invoked whenever the prettyprinter tries to look up a symbol that
2720 :     is not currently defined in the toplevel environment but which
2721 :     appears in CM's autoload registry. As a result, we see far fewer of
2722 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
2723 :    
2724 :     In addition to this I tried to clean up some pieces of the Basis
2725 :     implementation (e.g., Socket, Word8Array) in order to prevent other
2726 :     instances of these ?.Foo.Bar.xxx names from being printed.
2727 :    
2728 :     The mechanism that picks names for types still needs some work, though.
2729 :     (Right now it seems that if there is a type A.t which is defined to
2730 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
2731 :     "?.B.u" although the perhaps more sensible solution would be to use
2732 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
2733 :     a chain of DEFtycs not farther than there are corresponding toplevel
2734 :     names in the current environment.)

2740 :     Description:
2741 :    
2742 :     Another installer tweak: All the ML code for the installer is now
2743 :     compiled during CMB.make and put into a little library called
2744 :     $smlnj/installer.cm. The installation then simply invokes
2745 :    
2746 :     sml -m $smlnj/installer.cm
2747 :    
2748 :     and everything happens automagically.
2749 :    
2750 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
2751 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
2752 :     and BINDIR.
2753 :    
2754 :     The new scheme guarantees that the ML code responsible for the installation
2755 :     is in sync with the APIs of the main system. Also, the installer is
2756 :     somewhat faster because the installer script is precompiled.

2773 :     Tag: blume-20030924-sockets
2774 :     Description:
2775 :    
2776 :     1. Fixed SOCKET API and implementation to match Basis spec.
2777 :     This required changing the internal representation of sockets to one
2778 :     that remembers (for each socket file descriptor) whether it is currently
2779 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
2780 :     call is made only if the state actually needs to change).
2781 :    
2782 :     2. OS-specific details of sockets were moved into separate files, thus
2783 :     making it possible to unify the bulk of the socket implementations
2784 :     between Unix and Win32.
2785 :    
2786 :     3. CML's socket API changed accordingly.
2787 :     (Note that we need to remove non-blocking functions from this API
2788 :     since they are redundant in the case of CML!)
2789 :    
2790 :     4. CML's socket implementation now makes use of non-blocking functions
2791 :     provided by Basis, thus removing all OS-dependent code from this part
2792 :     of CML.
2793 :    
2794 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

2906 :     Tag: blume-20030909-installer
2907 :     Description:
2908 :    
2909 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
2910 :     Modified config/install.bat to take advantage of it. Also modified
2911 :     config/install.sh (and called it config/new-install.sh) to take advantage
2912 :     of it on Unix systems. (The SML code is (supposed to be) platform-
2913 :     independent.)
2914 :    
2915 :     The installer can now install everything under Win32
2916 :     as well as under *nix as long as it compiles.
2917 :    
2918 :     Other changes:
2919 :    
2920 :     - made CML compile again under Win32
2921 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
2922 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
2923 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
2924 :     same as type int; under Win32 it isn't
2925 :     - fixed some slice-related problems in the win32-specific parts of CML
2926 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
2927 :     (under Win32, the volume name is case-insensitive, and the
2928 :     OS.Path code compares volume names for equality)

2934 :     Description:
2935 :    
2936 :     Made Win32 version of OS.FileSys.fullPath return current directory
2937 :     when given an empty string. This is what the spec says, and incidentally,
2938 :     CM depends on it. (CM otherwise goes into an infinite loop in certain
2939 :     cases when presented with the name of a non-existing .cm file.)

2944 : mblume 1352 Tag: blume-20030905-slices-etc
2945 : mblume 1350 Description:
2946 :    
2947 :     1. Changed interface to vectors and arrays in Basis to match
2948 :     (draft) Basis spec.
2949 :     2. Added signatures and implementations of slices according to
2950 :     Basis spec.
2951 :     3. Edited source code throughout the system to make it compile again
2952 :     under 1. and 2. (In some cases code had to be added to have it
2953 :     match the new signatures.)
2954 :     4. MLRISC should be backward-compatible: the copies of the originals
2955 :     of files that needed to change under 3. were retained, the .cm files
2956 :     check the compiler version number and use old versions when
2957 :     appropriate.
2958 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
2959 :     dirstream -> string option (in accordance with Basis spec).
2960 :     6. When generating code that counts lines, ml-lex used function
2961 :     CharVector.foldli, taking advantage of its old interface.
2962 :     This has been replaced with the corresponding code from
2963 :     CharVectorSlice. (html-lex must be re-lexed!)
2964 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
2965 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
2966 :     8. Removed temporary additions (fromInternal, toInternal) from the
2967 :     (now obsolete) IntInf in smlnj-lib/Util.
2968 :     9. Cleaned up structure Byte.
2969 :     10. Added localOffset, scan, and fromString to Date (according to spec).
2970 :     Cleaned/corrected implementation of Date.
2971 :     (Still need to check for correctness; implement better canonicalizeDate.)
2972 :     11. Added "scan" to signature IEEE_REAL.
2973 :     12. Some improvements to IntInf [in particular: efficiency-hack for
2974 :     mod and rem when second operand is 2 (for parity checks).]
2975 :     13. Changed representation of type Time.time, using a single IntInf.int
2976 :     value counting microseconds. This considerably simplified the
2977 :     implementation of structure Time. We now support negative time
2978 :     values; scan and fromString handle signs.
2979 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
2980 :     ArraySlice).

2985 :     Tag: blume-20030828-intinf
2986 :     Description:
2987 :    
2988 :     This is a major update which comes with a version number bump
2989 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
2990 :     and an implementation of IntInf in the Basis.
2991 :    
2992 :     There are a fairly large number of related changes and updates throughout
2993 :     the system:
2994 :    
2995 :     Basis:
2996 :     - Implemented IntInf.
2997 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
2998 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
2999 : mblume 1347 - Added FixedInt as a synonym for Int32.
3000 :    
3001 :     compiler:
3002 :     * Added support for a built-in intinf type.
3003 :     - literals
3004 :     - pattern matching
3005 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3006 :     - overloading on literals and operations
3007 :    
3008 :     This required adding a primitive type intinf, some additional
3009 :     primops, and implementations for several non-trivial intinf
3010 :     operations in Core. (The intinf type is completely abstract
3011 :     to the compiler; all operations get delegated back to the Core.)
3012 :    
3013 :     * Intinf equality is handled by polyequal. However, the compiler
3014 :     does not print its usual warning in this case (since polyequal
3015 :     is the right thing to do there).
3016 :    
3017 :     * Improved the organization of structure InlineT.
3018 :    
3019 :     * A word about conversion primops:
3020 :     If conversions involving intinf do not cancel out during
3021 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3022 : mblume 1347 Since all core access must be resolved already during the FLINT
3023 :     translate phase, it would be too late a the time of CPS contract
3024 : mblume 1348 to add new Core calls. For this reason, conversion primops
3025 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3026 :     they are supposed to convert, and 2. the Core function that
3027 :     can help with this conversion if necessary. If CPS contract
3028 : mblume 1348 eliminates a primop, then the associated Core function becomes
3029 :     dead and goes away. Intinf conversion primops that do not get
3030 :     eliminated by CPS contract get rewritten into calls of their
3031 :     core functions by a separate, new phase.
3032 : mblume 1347
3033 :     interactive system:
3034 :     - Control.Print.intinfDepth controls max length of intinf constants
3035 :     being printed. (Analogous to Control.Print.stringDepth.)
3036 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3037 :     duplicates; replaced some of the code with code that makes better
3038 :     use of library functionality.
3039 :    
3040 :     CM:
3041 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3042 :     are no longer silent.
3043 :    
3044 :     CKIT:
3045 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3046 :     in favor of LargeInt -- which is now the same as IntInf.
3047 :     CKIT-knowledgable people should check whether this is what's
3048 :     intended and otherwise change things back to using Int32 or
3049 :     FixedInt.
3050 :    
3051 :     Throughout the code:
3052 : mblume 1348 Started using IntInf.int literals and built-in operations
3053 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3072 :     Tag: blume-20030811-windows
3073 :     Description:
3074 :    
3075 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3076 :    
3077 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3078 :    
3079 :     This patch restores SML/NJ's ability to run under win32. There are a
3080 :     number of changes, including fixes for several bugs that had gone
3081 :     unnoticed until now:
3082 :    
3083 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3084 :     trying to run the win32 version from within cygwin.)
3085 :    
3086 :     - There are a number of simple .bat scripts that substitute for their
3087 :     corresponding Unix shell-scripts. (See below.)
3088 :    
3089 :     - The internals of ml-build have been modified slightly. The main
3090 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3091 :     using OS.Process.system, the ML process delegates this task back
3092 :     to the script. Otherwise problems arise in mixed environments such
3093 :     as Cygwin where scripts look and work like Unix scripts, but
3094 :     where OS.Process.system cannot run them.
3095 :    
3096 :     - In CM, the srcpath pickler used native pathname syntax -- which
3097 :     is incorrect in the case of cross-compilation. The new pickle format
3098 :     is independent of platform-specific naming conventions.
3099 :    
3100 :     - Path configuration files (such as lib/pathconfig) can now choose
3101 :     between native and standard syntax. Placing a line of the form
3102 :    
3103 :     standard!
3104 :    
3105 :     into the file causes all subsequent paths to be interpreted using
3106 :     CM standard pathname syntax (= Unix conventions); a line
3107 :    
3108 :     native!
3109 :    
3110 :     switches back to native style. This was needed so that
3111 :     path config files can be written portably, see src/system/pathconfig.
3112 :    
3113 :     - Runtime system:
3114 :    
3115 :     - win32-filesys.c: get_file_time and set_file_time now
3116 :     access modification time, not creation time.
3117 :    
3118 :     - I/O code made aware of new array representation.
3119 :    
3120 :     - Bug fixes in X86.prim.masm.
3121 :    
3122 :     - src/system/makeml made aware of win32. (For use under cygwin
3123 :     and other Unix-environments for windows.)
3124 :    
3125 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3126 :     which caused BinIO.inputAll to fail consistently.
3127 :    
3128 :     .bat scripts:
3129 :    
3130 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3131 :    
3132 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3133 :     applications (sml, ml-yacc, ml-lex).
3134 :     - ml-build.bat: analogous to ml-build.
3135 :     - config\install.bat: Analogous to config/install.sh. This requires
3136 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3137 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3138 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3139 :     and the bootfile hierarchy must have been unpacked under
3140 :     sml.boot.x86-win32.
3141 :     The script is very primitive and does a poor job at error checking.
3142 :     It only installs the base system, ml-lex, and ml-yacc. No other
3143 :     libraries are being installed (i.e., you get only those that
3144 :     are part of the compiler.)
3145 :     - link-sml.bat: analogous to .link-sml, but not currently used
3146 :    
3147 :     Unrelated bug fixes:
3148 :    
3149 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3150 :     types.
3151 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3152 :     otherwise.)

3176 :     Description:
3177 :    
3178 :     Two changes:
3179 :    
3180 :     1. Added a flag for controlling whether non-exhaustive bindings will
3181 :     be treated as errors (default is false).
3182 :     2. Cleaned up the *entire* source tree so that CMB.make goes through

3189 :     Description:
3190 :    
3191 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3192 :    
3193 :     This mainly affects the quality of error messages. However, some
3194 :     of the code is now more straightforward than before. (Treatment of
3195 :     the above four constructs in translate.sml is much simpler than
3196 :     the "macro-expansion" that was going on before. Plus, the mach-
3197 :     compiler no longer gets invoked just to be able to compile an
3198 :     if-expression.)
3199 :    
3200 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3201 :     interactive loop.

3214 :     o Ctrl-C handling may be flaky.
3215 :     o Windows system calls and Windows I/O are not supported.

3218 :    
3219 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3220 :    
3221 :     This is only needed for bootstrapping the cygwin version of smlnj.

3260 :     Description:
3261 :    
3262 :     Added a call of SrcPath.sync at the beginning of Parse.parse (in CM).
3263 :     This fixes the problem of CM getting confused by files that suddenly
3264 :     change their identity (e.g., by getting unlinked and recreated by some
3265 :     text editor such as vi). There might be a better/cheaper/cleaner way
3266 :     of doing this, but for now this will have to do.

3280 :     Description:
3281 :    
3282 : blume 1282 In good old tradition, there has been a slight hiccup so that we have
3283 :     to patch 110.42 after the fact. The old release tag has been replaced
3284 :     (see below).
3285 :    
3286 :     The change solves a problem with two competing approaches the
3287 :     configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
3288 :     each other's way.
3289 :    
3290 :     This change only affects the runtime system code and the installer script.
3291 :     (No new bootfiles.)

3315 :     Description:
3316 :    
3317 :     Sml now senses the SMLNJ_HOME environment variable. If this is set,
3318 :     then the bin dir is assumed to be in $SMLNJ_HOME/bin and (unless
3319 :     CM_PATHCONFIG is also set), the path configuration file is assumed
3320 :     to be in $SMLNJ_HOME/lib/pathconfig. This way one can easily move
3321 :     the entire tree to some other place and everything will "just work".
3322 :    
3323 :     (Companion commands such as ml-build and ml-makedepend also sense this
3324 :     variable.)

3357 :     Fixed a bug in translation of INLMAX (and INLMIN) for the floating-point
3358 :     case. (The sense of the isNaN test was reversed -- which made min and

3375 :     I back-ported my implementation of IEEEReal.fromString from the
3376 :     idlbasis-devel branch so that we can test it.
3377 :    
3378 :     Another small change is that ppDec tries to give more information
3379 :     than just "<sig>" in the case of functors. However, this code is
3380 :     broken in some mysterious way if the functor's body's signature
3381 :     has not been declared by ascription but gets inferred from the
3382 :     implementation. This needs fixing...

3449 :     registering MLRISC control ref cells with Controls after the fact)
3450 :     - Fixed messed-up controls priorities.
3451 :    
3452 :     * Removed again all the stuff from config/preloads that one wouldn't
3453 :     be able to preload at the time the initial heap image is built.
3454 :     (Many libraries, e.g., CML, do not exist yet at this time. The
3455 :     only libraries that can be preloaded via config/preloads are those
3456 :     that come bundled with the bootfiles.)

3481 :     Description:
3482 :    
3483 :     0. John Reppy made several modifications to the SML/NJ library.
3484 :     In particular, there is a shiny new controls-lib.cm.
3485 :    
3486 :     1. Pushed new controls interface through compiler so that everything
3487 :     compiles again.
3488 :    
3489 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3490 :     SML/NJ library (so that CML compiles again).
3491 :    
3492 :     3. Modified init scripts because XXX_DEFAULT environment variables
3493 :     are no longer with us. (Boot-time initialization is now done
3494 :     using the same environment variables that are also used for
3495 :     startup-time initialization of controls.)

3501 :     Description:
3502 :    
3503 :     All pseudo-ops emitted before the first segment declaration
3504 :     such as TEXT, DATA, and BSS directives are assumed to be global
3505 :     declarations and are emitted first in the assembly file. This is
3506 :     useful in a number of situations where one has pseudo-ops that are not
3507 :     specific to any segment, and also works around the constraint that one
3508 :     cannot have client pseudo-ops in the TEXT segment.
3509 :    
3510 :     Because no segment is associated with these declarations it is
3511 :     an error to allocate any space or objects before the first segment
3512 :     directive and an exception will be raised. However, we cannot make
3513 :     this check for client pseudo-ops.
3514 :    
3515 :     These top level declarations are a field in the CFG graph_info.
3516 :     In theory you can continue to add to this field after the CFG has been
3517 :     built -- provided you know what you are doing;-)

3530 :     from scratch.)

3540 :     Description:
3541 :    
3542 :     Applied the following bugfix provided by Emden Gansner:
3543 :    
3544 :     Output is corrupted when outputSubstr is used rather than output.
3545 :    
3546 : blume 2155 The problem occurs when a substring
3547 : blume 1189
3548 :     ss = (s, dataStart, dataLen)
3549 :    
3550 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3551 :     avail bytes of s, starting at index dataStart, are copied into the
3552 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3553 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3554 :     starting this copy at index dataStart+avail in s, the current code
3555 : blume 1189 starts the copy at index avail.
3556 :    
3557 :     Fix:
3558 :     In text-io-fn.sml, change line 695 from
3559 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3560 : blume 2155 to

3577 :     Description:
3578 :    
3579 :     Added full support for div/mod/rem/quot on the x86, using the machine
3580 :     instruction's two results (without clumsily recomputing the remainder)
3581 :     directly where appropriate.
3582 :    
3583 :     Some more extensive power-of-two support was added to the x86 instruction
3584 :     selector (avoiding expensive divs, mods, and muls where they can be
3585 :     replaced with cheaper shifts and masks). However, this sort of thing
3586 :     ought to be done earlier, e.g., within the CPS optimizer so that
3587 :     all architectures benefit from it.
3588 :    
3589 :     The compiler compiles to a fixed point, but changes might be somewhat
3590 :     fragile nevertheless. Please, report any strange things that you might
3591 :     see wrt. div/mod/quot/rem...

3597 :     Description:
3598 :    
3599 :     Fixed my broken div/mod logic. Unfortunately, this means that the
3600 :     inline code for div/mod now has one more comparison than before.
3601 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3602 :     The problem was with quotient = 0, because that alone does not tell
3603 :     us which way the rounding went. One then has to look at whether
3604 :     remainder and divisor have the same sign... :(
3605 :

3613 :    
3614 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
3615 :    
3616 :     Primops have changed. This means that the bin/boot-file formats have
3617 :     changed as well.
3618 :    
3619 :     To make sure that there is no confusion, I made a new version.
3620 :    
3621 :    
3622 :     CHANGES:
3623 :    
3624 :     * removed REMT from mltree (remainder should never overflow).
3625 :    
3626 :     * added primops to deal with divisions of all flavors to the frontend
3627 :    
3628 :     * handled these primops all the way through so they map to their respective
3629 :     MLRISC support
3630 :    
3631 :     * used these primops in the implementation of Int, Int32, Word, Word32
3632 :    
3633 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3634 :    
3635 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
3636 :    
3637 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3638 :     floating point
3639 :    
3640 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3641 :     and Real (but Real.abs maps to a separate floating-point-only primop)
3642 :    
3643 :    
3644 :     TODO items:
3645 :    
3646 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
3647 :     instructions because the machine instruction encoder cannot handle
3648 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
3649 :     REM in the first place, and REM is supported by the x86 machine coder.)
3650 :    
3651 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
3652 :     selection phase. (The two can be streamlined because the hardware
3653 :     delivers both quotient and remainder at the same time anyway.)
3654 :    
3655 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
3656 :     (Currently the behavior is inconsistent both across architectures and
3657 :     wrt. the draft Basis spec.)
3658 :    
3659 :     * Word8 should eventually be handled natively, too.
3660 :    
3661 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
3662 :     as if there currently is no execution path that could trigger it in
3663 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
3664 :     hold for things like multiplication and division.)

3671 :

3673 :     and rem) to MLRISC. In the course of doing so, I also rationalized
3674 :     the naming (no more annoying switch-around of DIV and QUOT), by
3675 :     parameterizing the operation by div_rounding_mode (which can be either
3676 :     DIV_TO_ZERO or DIV_TO_NEGINF).
3677 :    
3678 :     The generic MLTreeGen functor takes care of compiling all four
3679 :     operations down to only round-to-zero div.
3680 :    
3681 :     Missing pieces:
3682 :    
3683 :     * Doing something smarter than relying on MLTreeGen on architectures
3684 :     like, e.g., the x86 where hardware division delivers both quotient and
3685 :     remainder at the same time. With this, the implementation of the
3686 :     round-to-neginf operations could be further streamlined.
3687 :    
3688 :     * Remove inlining support for div/mod/rem from the frontend and replace it
3689 :     with primops that get carried through to the backend. Do this for all
3690 :     int and word types.

3696 :     Description:
3697 :    
3698 :     I improved (hopefully without breaking them) the implementation of Int.div,
3699 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
3700 :     advantage of the following observations:
3701 :    
3702 :     Let q = x quot y r = x rem y
3703 :     d = x div y m = x mod y
3704 :    
3705 :     where "quot" is the round-to-zero version of integer division that
3706 :     hardware usually provides. Then we have:
3707 :    
3708 :     r = x - q * y where neither the * nor the - will overflow
3709 :     d = if q >= 0 orelse x = q * y then q else q - 1
3710 :     where neither the * nor the - will overflow
3711 :     m = if q >= 0 orelse r = 0 then r else r + y
3712 :     where the + will not overflow
3713 :    
3714 :     This results in substantial simplification of the generated code.
3715 :     The following table shows the number of CFG nodes and edges generated
3716 :     for
3717 :     fun f (x, y) = x OPER y
3718 :     (* with OPER \in div, mod, quot, rem *)

3759 :     Description:
3760 :    
3761 :     1. Changes to FLINT primops:
3762 :    
3763 :     (* make a call to a C-function;
3764 :     * The primop carries C function prototype information and specifies
3765 :     * which of its (ML-) arguments are floating point. C prototype
3766 :     * information is for use by the backend, ML information is for
3767 :     * use by the CPS converter. *)
3768 :     | RAW_CCALL of { c_proto: CTypes.c_proto,
3769 :     ml_args: ccall_type list,
3770 :     ml_res_opt: ccall_type option,
3771 :     reentrant : bool
3772 :     } option
3773 :     (* Allocate uninitialized storage on the heap.
3774 :     * The record is meant to hold short-lived C objects, i.e., they
3775 : blume 2155 * are not ML pointers. With the tag, the representation is
3776 : leunga 1174 * the same as RECORD with tag tag_raw32 (sz=4), or tag_fblock (sz=8)
3777 :     *)
3778 : blume 2155 | RAW_RECORD of {tag:bool,sz:int}
3779 : leunga 1174 and ccall_type = CCALL_INT32 | CCALL_REAL64 | CCALL_ML_PTR
3780 :    
3781 :     2. These CPS primops are now overloaded:
3782 :    
3783 :     rawload of {kind:numkind}
3784 :     rawstore of {kind:numkind}
3785 :    
3786 :     The one argument form is:
3787 :    
3788 :     rawload {kind} address
3789 :    
3790 :     The two argument form is:
3791 : blume 2155
3792 : leunga 1174 rawload {kind} [ml object, byte-offset]
3793 :    
3794 :     3. RAW_CCALL/RCC now takes two extra arguments:
3795 :    
3796 :     a. The first is whether the C call is reentrant, i.e., whether
3797 :     ML state should be saved and restored.
3798 :     b. The second argument is a string argument specifying the name of
3799 :     library and the C function.
3800 :    
3801 :     These things are currently not handled in the code generator, yet.
3802 :    
3803 :     4. In CProto,
3804 :    
3805 : blume 2155 An encoding type of "bool" means "ml object" and is mapped into
3806 :     C prototype of PTR. Note that "bool" is different than "string",
3807 : leunga 1174 even though "string" is also mapped into PTR, because "bool"
3808 :     is assigned an CPS type of BOGt, while "string" is assigned INT32t.
3809 :    
3810 :     5. Pickler/unpicker
3811 :    
3812 :     Changed to handle RAW_RECORD and newest RAW_CCALL
3813 :    
3814 :     6. MLRiscGen,
3815 :    
3816 :     1. Changed to handle the new rawload/rawstore/rawrecord operators.
3817 :     2. Code for handling C Calls has been moved to a new module CPSCCalls,
3818 :     in the file CodeGen/cpscompile/cps-c-calls.sml
3819 :    
3820 :     7. Added the conditional move operator
3821 :    
3822 :     condmove of branch
3823 :    
3824 : blume 2155 to cps. Generation of this is still buggy so it is currently

3831 : george 1168 Description:
3832 :    
3833 : blume 2155 Implemented the Ball-Larus branch prediction-heuristics, and
3834 : george 1168 incorporated graphical viewers for control flow graphs.
3835 :    
3836 : george 1171 Ball-Larus Heuristics:
3837 : george 1168 ---------------------
3838 :     See the file compiler/CodeGen/cpscompile/cpsBranchProb.sml.
3839 :    
3840 :     By design it uses the Dempster-Shafer theory for combining
3841 :     probabilities. For example, in the function:
3842 :    
3843 :     fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)
3844 :    
3845 :     the ball-larus heuristics predicts that the n=0 is unlikely
3846 :     (OH-heuristic), and the 'then' branch is unlikely because of the
3847 :     RH-heuristic -- giving the 'then' branch an even lower combined
3848 : george 1171 probability using the Dempster-Shafer theory.
3849 : george 1168
3850 :     Finally, John Reppy's loop analysis in MLRISC, further lowers the
3851 :     probability of the 'then' branch because of the loop in the else
3852 :     branch.
3853 :    
3854 :    
3855 :     Graphical Viewing:
3856 : blume 2155 ------------------
3857 : george 1168 I merely plugged in Allen's graphical viewers into the compiler. The
3858 :     additional code is not much. At the top level, saying:
3859 :    
3860 :     Control.MLRISC.getFlag "cfg-graphical-view" := true;
3861 :    
3862 :     will display the graphical view of the control flow graph just before
3863 :     back-patching. daVinci must be in your path for this to work. If
3864 :     daVinci is not available, then the default viewer can be changed
3865 :     using:
3866 :    
3867 :     Control.MLRISC.getString "viewer"
3868 :    
3869 :     which can be set to "dot" or "vcg" for the corresponding viewers. Of
3870 :     course, these viewers must be in your path.
3871 :    
3872 :     The above will display the compilation unit at the level of clusters,
3873 :     many of which are small, boring, and un-interesting. Also setting:
3874 :    
3875 :     Control.MLRISC.getInt "cfg-graphical-view_size"
3876 :    
3877 :     will display clusters that are larger than the value set by the above.

3903 : blume 2155 1. Recoded the buggy parts of x86-fp.
3904 : leunga 1156
3905 :     a. All the block reordering code has been removed.
3906 :     We now depend on the block placement phases to do this work.
3907 :    
3908 :     b. Critical edge splitting code has been simplified and moved into the
3909 :     CFG modules, as where they belong.
3910 :    
3911 :     Both of these were quite buggy and complex. The code is now much, much
3912 :     simpler.
3913 :    
3914 :     2. X86 backend.
3915 :    
3916 :     a. Added instructions for 64-bit support. Instruction selection for
3917 :     64-bit has not been committed, however, since that
3918 : blume 2155 requires changes to MLTREE which haven't been approved by
3919 : leunga 1156 Lal and John.
3920 :    
3921 : blume 2155 b. Added support for FUCOMI and FUCOMIP when generating code for
3922 : leunga 1156 PentiumPro and above. We only generate these instructions in
3923 :     the fast-fp mode.
3924 :    
3925 : blume 2155 c. Added cases for JP and JNP in X86FreqProps.
3926 :    
3927 : leunga 1156 3. CFG
3928 :    
3929 :     CFG now has a bunch of methods for edge splitting and merging.
3930 :    
3931 :     4. Machine description.
3932 :    
3933 :     John's simplification of MLTREE_BASIS.fcond broke a few machine
3934 :     description things:
3935 :    
3936 :     rtl-build.{sig,sml} and hppa.mdl fixed.
3937 :    
3938 : blume 2155 NOTE: the machine description stuff in the repository is still broken.

3940 :     changes to MLTREE.

3962 :     This implements a generic mechanism for changing constness qualifiers
3963 :     anywhere within big C types without resorting to outright "casts".
3964 :     (So far, functions such as C.rw/C.ro or C.Ptr.rw/C.Ptr.ro only let you
3965 :     modify the constness at the outermost level.)
3966 :     The implementation of "convert" is based on the idea of "witness"
3967 :     values -- values that are not used by the operation but whose types
3968 :     "testify" to their applicability. On the implementation side, "convert"
3969 :     is simply a projection (returning its second curried argument). With

3998 :     1. Factored out the recently-added Controls : CONTROLS stuff and put

4000 :     this is under src/smlnj-lib/Controls.
4001 :    
4002 :     2. Changed the names of types and functions in this interface, so they

4006 :     'a registry -> 'a group

4012 :    
4013 :     5. Made the corresponding modifications to the rest of the code so that
4014 :     everything compiles again.
4015 :    
4016 :     6. Changed the implementation of Controls.MLRISC back to something closer
4017 :     to the original. In particular, this module (and therefore MLRISC)
4018 :     does not depend on Controls. There now is some link-time code in

4078 :     Description:
4079 :    
4080 :     Yet another version number bump (because of small changes to the
4081 :     binfile format). Version number is now 110.39.2. NEW BOOTFILES!
4082 :    
4083 :     Changes:
4084 :    
4085 :     The new pid generation scheme described a few weeks ago was overly
4086 :     complicated. I implemented a new mechanism that is simpler and
4087 :     provides a bit more "stability": Once CM has seen a compilation
4088 :     unit, it keeps its identity constant (as long as you do not delete
4089 :     those crucial CM/GUID/* files). This means that when you change
4090 : blume 1145 an interface, compile, then go back to the old interface, and
4091 : blume 1137 compile again, you arrive at the original pid.
4092 :    
4093 :     There now also is a mechanism that instructs CM to use the plain
4094 :     environment hash as a module's pid (effectively making its GUID
4095 :     the empty string). For this, "noguid" must be specified as an
4096 :     option to the .sml file in question within its .cm file.
4097 :     This is most useful for code that is being generated by tools such
4098 :     as ml-nlffigen (because during development programmers tend to
4099 :     erase the tool's entire output directory tree including CM's cached
4100 :     GUIDs). "noguid" is somewhat dangerous (since it can be used to locally
4101 :     revert to the old, broken behavior of SML/NJ, but in specific cases
4102 :     where there is no danger of interface confusion, its use is ok

4105 :     ml-nlffigen by default generates "noguid" annotations. They can be
4106 :     turned off by specifying -guid in its command line.

4121 :     Description:
4122 :    
4123 :     Tested the jump chain elimination on all architectures (except the
4124 :     hppa). This is on by default right now and is profitable for the
4125 :     alpha and x86, however, it may not be profitable for the sparc and ppc
4126 :     when compiling the compiler.
4127 :    
4128 : blume 2155 The gc test will typically jump to a label at the end of the cluster,
4129 :     where there is another jump to an external cluster containing the actual
4130 : george 1133 code to invoke gc. This is to allow factoring of common gc invocation
4131 :     sequences. That is to say, we generate:
4132 :    
4133 :     f:
4134 :     testgc
4135 :     ja L1 % jump if above to L1
4136 :    
4137 :     L1:
4138 :     jmp L2
4139 :    
4140 :    
4141 :     After jump chain elimination the 'ja L1' instructions is converted to
4142 :     'ja L2'. On the sparc and ppc, many of the 'ja L2' instructions may end
4143 :     up being implemented in their long form (if L2 is far away) using:
4144 :    
4145 :     jbe L3 % jump if below or equal to L3
4146 :     jmp L2
4147 :     L3:
4148 :     ...
4149 :    
4150 :    
4151 :     For large compilation units L2 may be far away.

4166 : leunga 1131 Description:
4167 :    
4168 : blume 2155 The representation of the empty string now points to a
4169 :     legal null terminated C string instead of unit. It is now possible
4170 :     to convert an ML string into C string with InlineT.CharVector.getData.
4171 : leunga 1131 This compiles into one single machine instruction.

4185 :     Description:
4186 :    
4187 :     Version number bumped to 110.39.1. NEW BOOTFILES!
4188 :    
4189 :     Entrypoints: non-zero offset into a code object where execution should begin.
4190 :    
4191 :     - Added the notion of an entrypoint to CodeObj.
4192 :     - Added reading/writing of entrypoint info to Binfile.
4193 :     - Made runtime system bootloader aware of entrypoints.
4194 :     - Use the address of the label of the first function given to mlriscGen
4195 :     as the entrypoint. This address is currently always 0, but it will
4196 :     not be 0 once we turn on block placement.
4197 :     - Removed the linkage cluster code (which was The Other Way(tm) of dealing
4198 :     with entry points) from mlriscGen.
