57 :     Description:
58 :    
59 :     - Aaron: fixed a number of bugs in ml-ulex.
60 :     - Matthias:
61 :     - added CM control "cm.force-tools"; this is false by default;
62 :     when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
63 :     will be forced to run regardless of whether or not their targets
64 :     are up-to-date
65 :     - changed installer code so that config/install.sh will re-build
66 :     heap images for all tools even if those heap images already existed

71 :     Description:
72 :    
73 :     After Aaron Turon's bug fix for ml-ulex (handling the ^ character
74 :     in legacy mode), re-ran the lexer generator on all lex input files
75 :     and committed the results.
76 :    
77 :     This should fix the problem with ckit and nlffi that was reported
78 :     by Vesa A. Norrman.

90 :     Date: 2007/05/31 14:55:00 CDT
91 :     Revision: 2650
92 :     Description:
93 :    
94 :     3rd merge of base from primop-branch-3 into the trunk.
95 :     Additional bug fixes included:
96 :    
97 :     * Timer.cpu_timer, etc. type printing corrected (by making
98 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
99 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
100 :     Stefan Monnier)
101 :    
102 :     ----------------------------------------------------------------------
103 : blume 2645 Name: Matthias Blume (http://www.tti-c.org/blume/)
104 :     Date: 2007/05/31 11:40:00 CDT
105 :     Description:
106 :    
107 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
108 :    
109 :     Also, changed the handling of "no core access": When translate.sml
110 :     needs access to a core exception at a time when the core has not
111 :     been set up yet (this only happens when compiling system/smlnj/init/*),
112 :     then don't bother generating the corresponding tests.
113 :    
114 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
115 :     the exception. Unfortunately, that confuses the plambda type checker.
116 :     Moreover, it does not do any good, because at runtime we don't expect
117 :     such an exception to be ever raised. (The code in system/smlnj/init/*
118 :     has to be written very carefully with this in mind!)

121 : mrainey 2639 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
122 :     Date: 2007/05/29
123 :     Description:
124 :    
125 :     Added FSQRT instructions for the AMD64 code generator.
126 :    
127 :     ----------------------------------------------------------------------
128 : blume 2626 Name: Matthias Blume (http://www.tti-c.org/blume/)
129 :     Date: 2007/05/29 19:00:00 CDT
130 :     Description:
131 :    
132 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
133 :     with an explicit test for zero division. This should fixes several
134 :     regressions and makes it possible for downstream optimization phases
135 :     to treat these operations as "pure" when they are applied to unsigned
136 :     operands.
137 :    
138 :     ----------------------------------------------------------------------
139 : mrainey 2622 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
140 :     Date: 2007/05/29
141 :     Description:
142 :    
143 :     Added the new MLRISC code generator for the AMD64. This version,
144 :     in contrast to the previous one, uses SSE registers and instructions
145 :     for all floating-point computations.

148 : jhr 2613 Name: John Reppy (http://www.cs.uchicago.edu/~jhr)
149 : jhr 2617 Date: 2007/05/29
150 : jhr 2613 Description:
151 :    
152 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
153 :     for bugs #1415 and #1416. We also now correctly handle format characters that
154 :     lie outside the specified set.
155 : jhr 2613
156 :     ----------------------------------------------------------------------
157 : blume 2610 Name: Matthias Blume (http://www.tti-c.org/blume/)
158 :     Date: 2007/05/23 22:30:00 CDT
159 :     Description:
160 :    
161 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
162 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
163 :    
164 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
165 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
166 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
167 :     while running CMB.make. The point is that the single symbol
168 :     NO_PLUGINS is definde in all three cases.)
169 :    
170 :     I changed the three locations within the sources that get compiled
171 :     during CMB.make where ml-yacc or ml-lex input is processed: When
172 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
173 :     is bypassed.
174 :    
175 :     When bootstrapping new versions of the compiler, there can be
176 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
177 :     are not available or otherwise not operational. In this case one can
178 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
179 :     do so, the following command should be issued at the interactive
180 :     prompt:
181 :    
182 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
183 :    
184 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
185 :     files that normally would be generated by ml-yacc and ml-lex.
186 :     (Copies of these files are in the repository.)

189 : dbm 2603 Name: David MacQueen (dbm@cs.uchicago.edu)
190 :     Date: 2007/5/23 17:23:00 CDT
191 :     Revision: 2603
192 :     Description:
193 :    
194 :     2nd merge of base from primop-branch-3 into the trunk.
195 :     Additional bug fixes included:
196 :     Date.scan and Date.fromString fixed;
197 :     Overloading resolution fixed and some type printing problems corrected.

200 : blume 2578 Name: Matthias Blume (http://www.tti-c.org/blume/)
201 : blume 2589 Date: 2007/05/23 09:50:00 CDT
202 :     Description:
203 :    
204 :     Changed the installation mechanism for CM tool plugins. These are
205 :     just libaries and now get installed like ordinary libaries.
206 :    
207 :     There are now a number of new installation targets that give some
208 :     fine-grain control over what classes and suffixes are known, and what
209 :     they will map to.
210 :     See config/targets for details.
211 :    
212 :     The code that caused plugin installation as part of running a
213 :     tool's "build" script has been removed. (The build script is for
214 :     building, not for installing.)
215 :    
216 :     ----------------------------------------------------------------------
217 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
218 : blume 2578 Date: 2007/05/22 11:50:00 CDT
219 :     Description:
220 :    
221 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
222 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
223 :     CM fail if a shell tool reports a non-success exit status. If
224 :     the control is set to true, then CM will press on after tool failures
225 :     in the event that the target files exist (even though they are
226 :     considered outdated). Turning the control to true can be useful for
227 :     bootstrapping.

230 : adrassi 2570 Name: Aaron Turon (http://www.cs.uchicago.edu/~adrassi)
231 :     Date: 2007/05/19
232 :     Description:
233 :    
234 :     Merge of ml-lpt revisions for 110.64.
235 :    
236 :     The name of several ml-lpt-lib modules has changed:
237 :     Repair => AntlrRepair
238 :     StreamPos => AntlrStreamPos
239 :     ErrHandlerFn => AntlrErrHandler
240 :     EBNF => AntlrEBNF
241 :    
242 :     The ml-antlr specification format has changed: declarations such as
243 :     %tokens and nonterminal definitions can occur *multiple* times in the
244 :     same specification. The semantics are such that each new declaration
245 :     extends the previous ones. This does not apply to %start or %name,
246 :     of course.
247 :    
248 :     Importing a grammar via %import now includes *all* declarations in from
249 :     the imported grammar, except for %name, %entry, and %start. Tokens
250 :     and nonterminals can be dropped using the new %dropping clause of the
251 :     %import directive; the separate %drop and %extend have been removed.
252 :    
253 :     We now allow optional type annotations on nonterminals, using the %nonterms
254 :     directive as in ml-yacc.
255 :    
256 :     The refcell construct is now implemented using SML's regular reference
257 :     cells, so the :== and !! notation has been deprecated.
258 :    
259 :     The ml-antlr tool now does much more checking of specifications, and
260 :     its error messages have been greatly improved. Error repair for
261 :     generated parsers has been completely rewritten, and is now both
262 :     much faster and more accurate.
263 :    
264 :     ml-ulex is now more lenient with escape codes (non-SML-standard
265 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
266 :     Also, character classes may now include a "-" character at the beginning
267 :     as is standard in most other regexp tools.
268 :    
269 :     All of these changes are documented in the user guide, which has
270 :     been updated and improved with this merge.

276 :     Description:
277 :    
278 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
279 :     Significant changes in FLINT and the front end, mostly having to do
280 :     with a reorganized system for handling primops. Various bug fixes
281 :     and improvements in printing signatures.

287 :    
288 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
289 :     The ml-antlr specification format has changed: declarations such as
290 :     %tokens and nonterminal definitions can occur *multiple* times in the
291 :     same specification. The semantics are such that each new declaration
292 :     extends the previous ones. Grammar extension constructs have also

337 :     Description:
338 :    
339 :     More Basis fixes: The Char.fromString (etc.) functions did not handle

420 :     Date: 2007/02/26
421 :     Description:
422 :    
423 :     Added preliminary support in MLRISC for Staged Allocation, a technique
424 :     for specifying calling conventions (see
425 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
426 :     Initially, we plan to use this code to generate C calls for the AMD64.
427 :    
428 :     The staged allocation code base resides in MLRISC/staged-allocation,
429 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

435 :    
436 :     Bug fix: when SaveCState was called with two values to save, a subsequent
437 :     GC could cause the RestoreCState to fail because the saved state had been

449 :    
450 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
451 :     of the range -128 ... 127. I've changed the code so that the range
452 :     check is disabled. Only the low order 8 bits of the immediate operand

460 :    
461 :     Eliminated any mention of lexgen. (Lexgen was an early precursor
462 :     to ml-ulex.)
463 :    
464 :     You should update your admin directory, so the shell scripts for

493 :     Date: 2007/01/31
494 :     Description:
495 :    
496 :     Brought ml-lpt manual up-to-date with the code. Many minor
497 :     improvements to the tools, and a few minor bugfixes. Prepared
498 :     ml-lpt-lib for integration with new UTF8 structure. Changed
499 :     the interface for creating streams in ml-ulex (we now support
500 :     stream creation from several kinds of sources). Overall, the
501 :     tools are now quite stable, and their interfaces are unlikely to
502 :     change in a way that would break compatibility. More work,
503 :     however, is needed in the documentation.

508 :     Description:
509 :    
510 :     Implemented library installer. Moved CM plugin code for
511 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
512 :     their respective trees. Implemented CM plugin for ml-ulex
513 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
514 :     and ml-antlr.
515 :    
516 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
517 :     CM tools. (It turns out to be too messy to do otherwise because
518 :     there is too much code that during installation relies on the presence
519 :     of these tools -- resulting in a tricky ordering problem.)

524 :     Description:
525 :    
526 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
527 :     Modified CM's startup code to use shiftArgs as it processes
528 :     command line arguments. This way, the init code in each .sml-file
529 :     or library that is mentioned at the top level will see only
530 :     those arguments that have not yet been processed at this point.
531 :     In other words, the init code can "seize control" and process the
532 :     remaining command line.

547 :     Added the UTF8 structure and signature from the Moby compiler to
548 :     the SML/NJ library (and the CML library). These modules will replace

599 :     Description:
600 :    
601 :     Added code to CM's "standard shell tool" implementation which
602 :     causes it to tolerate (with a warning) the situation where the shell
603 :     command fails (e.g., due to the shell command's non-existence)
604 :     as long as all target files exist.
605 :    
606 :     This makes it possible to, e.g., build ml-yacc from sources even if
607 :     svn checkout messed up the time stamps on files in such a way that
608 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
609 :     be needed to re-process yacc.grm, but obviously it might not yet be
610 :     available at that time.)

616 :    
617 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
618 :     recvVecFromNB' in the SOCKET signature. This error is actually
619 :     in the SML Basis specification too.

648 : blume 2193 Date: 2006/11/09 14:30:00 CST
649 :     Tag: release-110.60
650 :     Description:
651 :    
652 :     New working release (110.60). NEW BOOTFILES!
653 :    
654 :     This is the first subversion-hosted release. There are also changes
655 :     to the directory layout. Here is a table:
656 :    
657 :     (All pathnames are relative to the SML/NJ "root" directory.)
658 :    
659 :     config -> config
660 :    
661 :     src/cm -> base/cm
662 :     src/compiler -> base/compiler
663 :     src/runtime -> base/runtime
664 :     src/system -> base/system
665 :    
666 :     src/cm/pgraph -> pgraph
667 :    
668 :     src/READMES -> base/READMES
669 :     src/$notefile -> base/NOTES/$notefile
670 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
671 :     MACOSXINSTALL WININSTALL
672 :    
673 :     src/smlnj-lib -> smlnj-lib
674 :     src/MLRISC -> MLRISC
675 :     ckit -> ckit
676 :     src/cml -> cml
677 :     src/eXene -> eXene
678 :     src/heap2asm -> heap2asm
679 :     src/lexgen -> lexgen
680 :     src/ml-burg -> ml-burg
681 :     src/ml-lex -> ml-lex
682 :     src/ml-yacc -> ml-yacc
683 :     src/ml-nlffi-lib -> nlffi/lib
684 :     src/ml-nlffigen -> nlffi/gen
685 :     src/smlnj-c -> smlnj-c
686 :     src/tools/TraceDebugProf -> trace-debug-profile
687 :    
688 :     In addition, there is also a new
689 :    
690 :     ml-lpt
691 :    
692 :     directory containing two new program generator tools: ml-ulex and
693 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
694 :     LL(k) parser generator). These tools are currently "beta-quality"
695 :    
696 :     The latest versios of the sources can now be obtained anonymously
697 :     via subversion. For this, it is useful to first check out
698 :    
699 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
700 :    
701 :     and put the resulting directory on your shell's PATH. This provides
702 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
703 :     and refresh-all.sh.
704 :    
705 :     To create a freshly checked-out copy of the sources, do
706 :    
707 :     checkout-all.sh [dir]
708 :    
709 :     where dir is the optional SML/NJ root directory (default is ".").
710 :    
711 :     This creates the above directory layout. Each subdirectory of
712 :     the root is under individual subversion control. The stat-all.sh
713 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
714 :     each of these subtrees.
715 :    
716 :     ----------------------------------------------------------------------
717 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
718 : blume 2155 Date: 2006/11/02 12:20:00 CST
719 :     Description:
720 :    
721 :     Reorganized directory layout.
722 :    
723 :     This is a temporary solution, more reorganization is to come.
724 :    
725 :     The basic idea is to have a number of toplevel trees, each corresponding
726 :     to a well-defined part of the overall system. Each part can be
727 :     maintained individually, even in separate source repositories,
728 :     although currently we still serve everything out of the main
729 :     smlnj-gforge tree.
730 :    
731 :     Installer and and scripts have been updated to reflect the new
732 :     layout. The installer (base/src/system/smlnj/installer) is now
733 :     "scriptable" to avoid burning too much knowledge about the
734 :     layout into SML source code. The main script used by the installer
735 :     is in config/actions.
736 :    
737 :     The main change is that many of the subdirectories of what used to
738 :     be known as "src" have moved to the toplevel. The "src" directory
739 :     itself has moved down into a subtree called "base". (We may eventually
740 :     get rid of the extra level of indirection represented by "src".)
741 :    
742 :     The layout is now as follows:
743 :    
744 :     toplevel tree name | default repository
745 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
746 :     -------------------+----------------------------------------------------
747 :     config | $gf/config/trunk
748 :     |
749 :     base | $gf/sml/trunk
750 :     |
751 :     smlnj-lib | $gf/smlnj-lib/trunk
752 :     MLRISC | $gf/MLRISC/trunk
753 :     |
754 :     ml-yacc | $gf/ml-yacc/trunk
755 :     ml-lex | $gf/ml-lex/trunk
756 :     ml-burg | $gf/ml-burg/trunk
757 :     lexgen | $gf/lexgen/trunk
758 :     heap2asm | $gf/heap2asm/trunk
759 :     |
760 :     cml | $gf/cml/trunk
761 :     eXene | $gf/eXene/trunk
762 :     ckit | $gf/ckit/trunk
763 :     nlffi | $gf/nlffi/trunk
764 :     |
765 :     smlnj-c | $gf/smlnj-c/trunk
766 :    
767 :     In $gf/admin there are a few useful shell scripts for checking out
768 :     and maintaining the entire collection of trees:
769 :    
770 :     admin/checkout-all.sh [dir]
771 :     -- optionally creates dir and checks out all trees from their
772 :     default repositories; if dir is missing, checkout into .
773 :     admin/refresh-all.sh [dir]
774 :     -- looks at all trees (from the above list) in dir (default: .)
775 :     and runs "svn update" if the tree exists and is under
776 :     subversion control;
777 :     non-existing or non-subversion trees are skipped
778 :     admin/stat-all.sh [dir]
779 :     -- like refresh-all.sh, but runs "svn stat" instead

925 :     Description:
926 :    
927 :     Hooked code for Darwin-specific Intel ABI into main compiler.
928 :     (This is a temporary solution which relies on the fact that the
929 :     compiler itself does not use NLFFI. Eventually we need to divorce
930 :     intel mac from generic x86 unix code and make separate sets of binaries.)

959 :     Description:
960 :    
961 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
962 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
963 : blume 2155 at the time when config/preloads is processed, the library has to
964 : mblume 1878 be referred to by another name. In 110.57 this would be
965 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
966 :     to be valid as well.)
967 :    
968 :     Thanks to Todd Wilson (Fresno) for alerting me to this issue.

982 :     Description:
983 :    
984 :     Fixed a problem in config/install.sh where it tries to "fish" the
985 :     name of the CM metadata directory from the wrong place (because
986 :     the physical location of basis.cm has changed). Also, corrected the
987 :     path anchor for $/html-lib.cm. (Thanks to M. Fluet for pointing out

1021 :     Tag: blume-22051115-versiontool
1022 :     Description:
1023 :    
1024 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1025 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1026 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1027 :     it. Instead, it has the status of "user code", so it should use
1028 :     $/basis.cm to refer to the Basis library. (At least that's true for
1029 :     the purpose of bootstrapping the previous change. In the future it
1030 :     might make sense to have versiontool.cm refer to
1031 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1032 :     compiler itself uses.)
1033 :    
1034 :     Also patched src/system/testml to have it activate those extra anchor
1035 :     bindings in config/extrapathconfig.

1040 :     Tag: blume-22051115-libraries
1041 :     Description:
1042 :    
1043 :     This change affects the way the following libraries are tied into
1044 :     the system:
1045 :    
1046 :     $/basis.cm
1047 :     $/smlnj-lib.cm
1048 :     $/pp-lib.cm
1049 :     $/controls-lib.cm
1050 :     $/html-lib.cm
1051 :     $/ml-yacc-lib.cm
1052 :    
1053 :     These libraries are now internally (as seen from the source code
1054 :     of the implementation itself) known by the following names:
1055 :    
1056 :     $smlnj/basis/basis.cm
1057 :     $smlnj/smlnj-lib/smlnj-lib.cm
1058 :     $smlnj/smlnj-lib/pp-lib.cm
1059 :     $smlnj/smlnj-lib/controls-lib.cm
1060 :     $smlnj/smlnj-lib/html-lib.cm
1061 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1062 :    
1063 :     This makes it possible to work with code that requires different
1064 :     versions of these libraries, and which refers to these libraries using
1065 :     their "default" names (i.e., the first set of names above). In other
1066 :     words, one can un-define or re-define those default names without
1067 :     compromising the proper functioning of the compiler itself.
1068 :    
1069 :     A similar procedure had already been performed for several of the
1070 :     MLRISC libraries that are linked into the compiler. I did some
1071 :     cleanup on this code.
1072 :    
1073 :     A new file in the config directory (named extrapathconfig) is
1074 :     responsible for setting up path anchors that the compiler itself does
1075 :     not need, but that are typically required by user code.

1255 :     Description:
1256 :    
1257 :     Added mechanism for re-creating a heap file for the interactive system
1258 :     after configuration variables have been changed.
1259 :    
1260 :     CM.redump_heap : string -> unit
1261 :    
1262 :     This is much like SMLofNJ.exportML, but starting from the resulting
1263 : blume 2155 heap does not return to the caller of CM.redump_heap but
1264 : mblume 1792 restarts the interactive system from scratch. The original call of
1265 :     CM.redump_heap does not return but ends the interactive session.
1266 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1267 :    
1268 :     Internally, redump_heap winds the dynamic execution context back to
1269 :     the point where the original heap image was created and re-executes
1270 :     the heap image generation code in the boot code.

1276 :     Description:
1277 :    
1278 :     Added a hack to the existing hack known as Word64 to make fromString
1279 :     behave correctly. I am still not sure whether Word64.scan will work
1280 :     as specified with respect to the interaction of radix and prefix.

1387 :     Description:
1388 :    
1389 :     Implemented new (but still experimental) heap2exec facility. This is
1390 :     tested under Mac OS X and should work under Linux (will test shortly).
1391 :     It will probably also work on the Sparc (will test some time later).
1392 :    
1393 :     - removed old "HACKED_STANDALONE" hack from runtime
1394 :    
1395 :     To be able to test this, uncomment the request for "heap2asm" in
1396 :     config/targets prior to installation. (Notice that this is different
1397 :     from "heap2exec" mentioned below. Not a typo.)
1398 :    
1399 :     To perform an actual test, run the command
1400 :    
1401 :     $ bin/heap2exec heapfile execfile
1402 :    
1403 :     (You can put heap2exec on your shell's path.)
1404 :    
1405 :     For example, run
1406 :    
1407 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1408 :    
1409 :     This will create a standalone executable called "mly" which you can
1410 :     then invoke directly as a command.

1437 :    
1438 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1439 :     (On the Mac, it is big-endian. And that's currently our only
1440 :     PPC platform.)

1555 :     Tag: blume-20041124-position
1556 :     Description:
1557 :    
1558 :     The compiler can now be compiled in a mode that makes structure Position
1559 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1560 :     for the time being.
1561 :    
1562 :     To enable 64-bit positions, use the following procedure:
1563 :    
1564 :     1. Start sml
1565 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1566 :     3. Type
1567 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1568 :     4. Run CMB.make() as usual.
1569 :    
1570 :     This is barely tested. The only test so far was a little SML program
1571 :     counting the number of characters in an 8-gigabyte file by
1572 :     reading it character-by-character. That test was successful.
1573 :    
1574 :     In support of 64-bit positions, a number of new functions have been
1575 :     added to the runtime system.

1620 :    
1621 :     - In a previous commit, fixed a minor issue with how polyequal is being
1622 :     translated. In particular, the code now "looks through" abstractions.
1623 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1624 :     more efficient code. Important examples for where this matters are
1625 :     the new int64 and word64 types.

1644 :     but for the time being they don't even make sense because LargeWord is
1645 :     32-bit wide.)
1646 :    
1647 :     Also started to add similar support for Int64, but major pieces of that
1648 :     are still missing.

1654 :     Description:
1655 :    
1656 :     Structure Word64 is now (almost) complete, word literals and patterns
1657 :     seem to work. There are a few odd pieces missing. In particular,
1658 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1659 :     at the moment.
1660 :    
1661 :     Making Word64 official would mean that LargeWord becomes Word64. But
1662 :     this requires extreme care because most word-word conversions have to
1663 :     go through LargeWord, so making a mistake means loss of efficiency or
1664 :     worse. Eventually there will be a solution similar to (but actually
1665 :     simpler than) what I did with IntInf.

1671 :     Description:
1672 :    
1673 :     More 64-bit hacking (but still not even half-way there yet).
1674 :     Also, some assorted improvements to the handling of 8-bit words.

1690 :    
1691 :     New working version (110.50). NEW BOOTFILES!
1692 :    
1693 :     =====================
1694 :    
1695 :     Also:
1696 :    
1697 :     - Changend config/srcarchiveurl from a file just
1698 :     containing the URL string into a file containing
1699 :     shell script code. The code has access to the $VERSION variable.
1700 :     - Made corresponding changes to config/install.sh and config/unpack.
1701 :     - Default contents of config/srcarchiveurl uses $VERSION and
1702 :     normally does not have to be edited to reflect a version change.
1703 :    
1704 :     (As a result, a version change can be done by just editing
1705 :     config/version, the rest is now automatic.)

1723 :     the x86 c-calls code in MLRISC:
1724 :    
1725 :     - added a missing LOAD in the code that deals with struct arguments
1726 :     - made sure the caller does not add the wrong number of bytes to the
1727 :     stack pointer after a call of a function returning a struct
1728 :     (the callee already pops the implicit argument which points to
1729 :     the space reserved for the result)

1745 :     Tag: blume-20041020-standalone-backtrace
1746 :     Description:
1747 :    
1748 :     Added a mechanism for getting back-trace information from standalone
1749 :     programs. Here is how it works:
1750 :    
1751 :     1. The part of the program from which you want to get backtrace
1752 :     information (usually the whole program) should be wrapped with
1753 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
1754 :     main program could be modified from something like
1755 :    
1756 :     fun main (pgm, args) = ...
1757 :    
1758 :     to
1759 :    
1760 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1761 :    
1762 :     2. To be able to access BackTrace.monitor, you have to add
1763 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
1764 :     main function.
1765 :    
1766 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1767 :     CM might have created in the past for your project).
1768 :    
1769 :     4. Build the system using this command line:
1770 :    
1771 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1772 :     myprog.cm MyProg.main myprog
1773 :    
1774 :     instead of the usual
1775 :    
1776 :     ml-build myprog.cm MyProg.main myprog
1777 :    
1778 :     I changed a library name:
1779 :    
1780 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1781 :    
1782 :     New libraries:
1783 :    
1784 :     $smlnj-tdp/back-trace.cm
1785 :     -- when loaded causes the back-trace plugin to be installed
1786 :     $smlnj-tdp/coverage.cm
1787 :     -- when loaded causes the coverage plugin to be installed

1802 :     Tag: blume-20041015-coverage
1803 :     Description:
1804 :    
1805 :     * Test coverage tool added!
1806 :     * Further reorganization of tracing-, debugging-, and profiling support:
1807 :    
1808 :     - moved original BTImp -- now called BackTrace -- into a separate
1809 :     library called $/trace-debug-profile.cm
1810 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
1811 :     - only the instrumentation mechanism is now left in the compiler proper
1812 :     - BackTrace module is a plugin which is NOT plugged in by default
1813 :     - Coverage module is another such plugin
1814 :    
1815 :     To get the benefits of any of these plugin modules, the code in
1816 :     question must be compiled with tdp instrumentation turned on. This
1817 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
1818 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1819 :    
1820 :     Plugins are selected at link time. (Pre-compiled instrumented code
1821 :     can be re-loaded with different plugins in effect.) When an
1822 :     instrumented module is linked, whatever plugins are at that time
1823 :     enabled will come into effect for that module.
1824 :    
1825 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
1826 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
1827 :     To enable the coverage plugin, load the same library and invoke
1828 :     Coverage.install().
1829 :    
1830 :     Back-traces are generated automatically on uncaught exceptions and
1831 :     when the code in question explicitly invokes BackTrace.trigger().
1832 :    
1833 :     Coverage (and execution frequency-) information must be queried
1834 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

1850 :    
1851 :     Some rationalization of names:

1854 :     etc.
1855 :    
1856 :     This is is preparation of using the original back-trace
1857 :     instrumentation for other purposes. "TDP" stands for
1858 :     Trace/Debug/Profile.
1859 :    
1860 :     The control flag controlling whether instrumentation is on or off is now
1861 :     registered under a different name, so instead of running sml as
1862 :    
1863 :     sml -Cinstrument.btrace-mode=true

1883 :     Description:
1884 :

1886 :     treats subsequent occurrences of "group", "library", "source", "is",
1887 :     "*", and "-" as ordinary identifiers rather than keywords.
1888 :    
1889 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool
1890 :     is supposed to accept a tool argument called "source", but this did
1891 :     not work because of the clash with the keyword.

1935 :    
1936 :     * Moved the "version" magic into its own little library under

1942 : mblume 1639
1943 :     * Arranged for the version tool to NOT kick in when rebuilding the system
1944 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
1945 :     Also, loading the versiontool does not work when rebuilding the system
1946 :     because CM is not properly initialized at that time.

1951 :     Tag: blume-20040929-autoversion
1952 :     Description:
1953 :    
1954 :     Implemented some CM magic to have
1955 :     file src/compiler/TopLevel/main/version.sml
1956 :     generated automagically.
1957 :     The version is taken from two files: config/version and config/release.
1958 :     The first is expected to contain a two-part version number such as 110.49.
1959 :     The second should contain a single number, but it may be missing.
1960 :    
1961 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
1962 :     time the version tool is loaded (which is the first time you say CMB.make),
1963 :     then the tool will increment the value stored in config/release every
1964 :     time CMB.make is invoked.
1965 :    
1966 :     The binfile format is now insensitive to anything beyond the first
1967 :     two components of a version number, so bumping the release does not render
1968 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
1969 :     during development without invalidating existing binfiles.
1970 :    
1971 :     In any case, every CMB.make updates the date information in version.sml.
1972 :     (This is the date that is printed in the banner.)

1985 :     Tag: blume-20040927-controls
1986 :     Description:
1987 :    
1988 :     Added two pieces of functionality to the Controls interface:
1989 :    
1990 :     1. val save'restore: 'a control -> unit -> unit
1991 :    
1992 :     grabs the current value of the control in stage 1 and restores it
1993 :     in stage 2.
1994 :    
1995 :     2. val set' : 'a control * 'a -> unit -> unit
1996 :    
1997 :     stores the given value into the control in stage 2 (i.e., delayed)
1998 :     but does all error checking in stage 1.
1999 :     (This is for string controls that need to do parse their argument --
2000 :     something that might fail. In some cases, notably in CM, one
2001 :     already knows the intended argument but wants to delay the actual
2002 :     assignment until a time when error recovery would be more difficult.)
2003 :    
2004 :     Changed the handling of controls in tool arguments to classes "sml" and
2005 :     "lazysml":
2006 :     - use Controls.save'restore as a more robust way of restoring the
2007 :     old value (in particular: without having to re-parse the string)
2008 :     - use controls to handle the "overload" keyword in the init group
2009 :     (I believe this change actually fixes a long-standing obscure bug.)

2014 :     Tag: blume-20040927-lazysml
2015 :     Description:
2016 :    
2017 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2018 :     difference to "sml" is that compilation is done with Control.lazysml
2019 :     set to true. A source of class "lazysml" is automatically recognized
2020 :     by a file name suffix of ".lml".
2021 :    
2022 :     In addition to the above feature, the original class "sml" now also
2023 :     supports a tool argument "lazy" which has the same effect. As a
2024 :     result, the following three lines are equivalent:
2025 :    
2026 :     foo.sml : lazysml
2027 :     foo.sml : sml (lazy)
2028 :     foo.sml (lazy)
2029 :    
2030 :     The setting goes into effect both during parsing and during
2031 :     compilation. The original setting is restored right after parsing and
2032 :     after compilation, respectively.
2033 :    
2034 :     In addition to all the above, there is also a general mechanism to set
2035 :     ANY of the "controls" that are available at the command line via
2036 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2037 :     apply as well. (In fact, "lazy" is implemented as a special case of
2038 :     the general mechanism.)
2039 :    
2040 :     The .cm file syntax uses a new keyword tool argument called "with".
2041 :     There are several ways of indicating the desired settings:
2042 :    
2043 :     foo.sml (with:parser.quotations=true)
2044 :     foo.sml (with:(name:parser.quotations value:true))
2045 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2046 :     foo.sml (with:(name1=value1 name2=value2 ...))
2047 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2048 :    
2049 :     etc.
2050 :    
2051 :     Another possible abbreviation is to leave out the =v or value:v part
2052 :     if the name refers to a boolean control (in which case the value is
2053 :     taken to be true). Thus, one could get lazy sml also by saying:
2054 :    
2055 :     foo.sml (with:parser.lazy-keyword=true)
2056 :     foo.sml (with:parser.lazy-keyword)
2057 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2058 :     foo.sml (with:(name:parser.lazy-keyword))

2410 :     Description:
2411 :    
2412 :     Changed the interface of structures Timer and Unix to match the most
2413 :     recent Basis spec.
2414 :    
2415 :     In the case of Unix there still seems to be an open/weird issue:
2416 :    
2417 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2418 :     fresh streams whenever they are called -- as opposed to have them
2419 :     return the same stream every time. This design is supposed to
2420 :     prevent space leaks caused by proc values hanging on to streams.
2421 :    
2422 :     The reap function, on the other hand, is supposed to close the
2423 :     streams. This cannot be done without having a handle on the
2424 :     stream in proc after all...
2425 :    
2426 :     I took the liberty to implement the following stopgap solution:
2427 :    
2428 :     The proc value hangs on to the most recently created stream(s).
2429 :     Reap closes those. If either or both of the two streams hadn't
2430 :     been created at all yet, then reap will close the corresponding
2431 :     file descriptors directly.
2432 :    
2433 :     PS: I don't understand the original space leak argument anymore. If
2434 :     a proc hangs on to the imperative stream, then I/O operations on those
2435 :     will advance the state of the cached stream and avoid the space leak.

2448 :     Tag: blume-20040525-group-owner
2449 :     Description:
2450 :    
2451 :     CM now ignores (but still accepts) the "owner" information in group
2452 :     descriptions. The owner of a group is its next enclosing
2453 :     library. Each group must have a unique owner. (There is a virtual
2454 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2455 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2456 :     and CM would check that such a declaration is correct. The new scheme
2457 :     is to have CM check that for each group there is precisely one owning
2458 :     library.
2459 :    
2460 :     The advantage of the new scheme is that the programmer no longer needs
2461 :     to maintain the somewhat annoying owner information. The downside is
2462 :     that CM cannot enforce the ownership rule across multiple runs of
2463 :     CM.make. Fortunately, enclosing the same group in two different
2464 :     libraries A and B which are not part of the same program does not
2465 :     cause real problems.

2472 :    
2473 :     Made the win32 version work again. (Strangely, a misplaced comma had
2474 :     slipped into win32-process.c which prevented the runtime from being
2475 :     compiled correctly.)
2476 :    
2477 :     Also, included a minor addition to ml-build.bat analogous to what was
2478 :     done in blume-20040519-ml-build.

2483 :     Tag: blume-20040519-ml-build
2484 :     Description:
2485 :    
2486 :     Arranged for ml-build to clean up after itself a little bit better.
2487 :     The script generates a temporary SML source file and compiles it using
2488 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
2489 :     gets rid of those at the end, so they don't accumulate under .cm.
2490 :    
2491 :     This required a minor change to install.sh because the name of the
2492 :     metadata directory (default: .cm) is actually configurable at
2493 :     installation time.

2508 :     Description:
2509 :    
2510 :     Added previously missing support for many socket-related functions
2511 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
2512 :     for the voluminous patch!
2513 :    
2514 :     (I have not tested this patch under win32 yet.)
2515 :    
2516 : mblume 1490 Here is David's e-mail:
2517 :    
2518 :     Hi,
2519 :    
2520 :     Attached to this email you find a diff against sml/nj 110.45
2521 :     that will enable socket support under Windows.
2522 :    
2523 :     To apply the patch (using unix or cygwin)
2524 :     1) gunzip runtime.diff.gz
2525 :     2) "cd" into "src/runtime" in the source tree of a fresh
2526 :     110.45 installation.
2527 :     3) patch -p 1 < [your/path/to]runtime.diff
2528 :    
2529 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2530 :     I only ran a few tests for basic socket client functionality
2531 :     (which worked fine). Especially the functions that use ioctl
2532 : mblume 1490 are not tested at all and might not work (see below).
2533 :    
2534 :     I implemented this since we want to move to a newer version of sml/nj
2535 :     but need socket support in order to use it. This is the first time I
2536 :     even had a look at the sml/nj source, so please review my changes
2537 :     before making this part of the distribution! Here are a few issues
2538 : blume 2155 that I think might be better for someone to solve who is more
2539 : mblume 1490 familiar with the sml/nj source (and socket programming):
2540 :    
2541 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2542 :     exception since I could not figure out what the windows equivalent
2543 :     of these functions is
2544 :    
2545 :     - In sockets-osdep.h there are a some #include statements that are
2546 :     only used in a few files that include sockets-osdep.h
2547 :    
2548 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2549 :     does not process its return value since I don't know how to
2550 :     report an error upwards.
2551 :    
2552 :     - It would probably be good to have a call to WSACleanup() when
2553 : blume 2155 the library is unloaded (if there is such a possibility).
2554 : mblume 1490 Otherwise I think Windows will take care of this automatically
2555 :     when the process finishes.
2556 :    
2557 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2558 :     no idea if that is actually the proper replacement on Windows.
2559 :    
2560 :     - All these issues are marked in the code by "FIXME" comments.
2561 :    
2562 : blume 2155 We use sml/nj extensively in our products and are quite happy
2563 :     with it. I hope this contribution will help you.
2564 : mblume 1490
2565 :     Keep up the good work!

2643 :

2646 :    
2647 :     lib = dlopen(NULL, ...)
2648 :     f = dlsym(lib, "malloc");
2649 :    
2650 : blume 2155 does not work on Windows unless we explicitly export symbols
2651 :     such as 'malloc' during linking. We fixed this by explicitly
2652 : allenleung 1468 exporting the required symbols with the magic gcc incantation:
2653 :    
2654 :     -Wl,--export-all cygwin.def
2655 :    
2656 :     where cygwin.def is a file containing all the symbols that
2657 : blume 2155 we wish to export.
2658 : allenleung 1468
2659 : blume 2155 I suspect this is a Windows problem and we'll have to
2660 :     do the same (somehow with windows compilers) when
2661 : allenleung 1468 we build the native win32 version with the system
2662 : blume 2155 calls LoadLibrary/GetProcAddress.

2788 :     Description:
2789 :    
2790 :     I modified the read-eval-print loop so that the autoloader gets
2791 :     invoked whenever the prettyprinter tries to look up a symbol that
2792 :     is not currently defined in the toplevel environment but which
2793 :     appears in CM's autoload registry. As a result, we see far fewer of
2794 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
2795 :    
2796 :     In addition to this I tried to clean up some pieces of the Basis
2797 :     implementation (e.g., Socket, Word8Array) in order to prevent other
2798 :     instances of these ?.Foo.Bar.xxx names from being printed.
2799 :    
2800 :     The mechanism that picks names for types still needs some work, though.
2801 :     (Right now it seems that if there is a type A.t which is defined to
2802 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
2803 :     "?.B.u" although the perhaps more sensible solution would be to use
2804 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
2805 :     a chain of DEFtycs not farther than there are corresponding toplevel
2806 :     names in the current environment.)

2812 :     Description:
2813 :    
2814 :     Another installer tweak: All the ML code for the installer is now
2815 :     compiled during CMB.make and put into a little library called
2816 :     $smlnj/installer.cm. The installation then simply invokes
2817 :    
2818 :     sml -m $smlnj/installer.cm
2819 :    
2820 :     and everything happens automagically.
2821 :    
2822 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
2823 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
2824 :     and BINDIR.
2825 :    
2826 :     The new scheme guarantees that the ML code responsible for the installation
2827 :     is in sync with the APIs of the main system. Also, the installer is
2828 :     somewhat faster because the installer script is precompiled.

2845 :     Tag: blume-20030924-sockets
2846 :     Description:
2847 :    
2848 :     1. Fixed SOCKET API and implementation to match Basis spec.
2849 :     This required changing the internal representation of sockets to one
2850 :     that remembers (for each socket file descriptor) whether it is currently
2851 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
2852 :     call is made only if the state actually needs to change).
2853 :    
2854 :     2. OS-specific details of sockets were moved into separate files, thus
2855 :     making it possible to unify the bulk of the socket implementations
2856 :     between Unix and Win32.
2857 :    
2858 :     3. CML's socket API changed accordingly.
2859 :     (Note that we need to remove non-blocking functions from this API
2860 :     since they are redundant in the case of CML!)
2861 :    
2862 :     4. CML's socket implementation now makes use of non-blocking functions
2863 :     provided by Basis, thus removing all OS-dependent code from this part
2864 :     of CML.
2865 :    
2866 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

2908 :    
2909 :     1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as

2912 :

2915 :     3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
2916 :     For example, fromLargeInt never needs to look at more than 3 "big

2978 :     Tag: blume-20030909-installer
2979 :     Description:
2980 :    
2981 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
2982 :     Modified config/install.bat to take advantage of it. Also modified
2983 :     config/install.sh (and called it config/new-install.sh) to take advantage
2984 :     of it on Unix systems. (The SML code is (supposed to be) platform-
2985 :     independent.)
2986 :    
2987 :     The installer can now install everything under Win32
2988 :     as well as under *nix as long as it compiles.
2989 :    
2990 :     Other changes:
2991 :    
2992 :     - made CML compile again under Win32
2993 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
2994 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
2995 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
2996 :     same as type int; under Win32 it isn't
2997 :     - fixed some slice-related problems in the win32-specific parts of CML
2998 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
2999 :     (under Win32, the volume name is case-insensitive, and the
3000 :     OS.Path code compares volume names for equality)

3010 :     CM depends on it. (CM otherwise goes into an infinite loop in certain

3016 : mblume 1352 Tag: blume-20030905-slices-etc
3017 : mblume 1350 Description:
3018 :    
3019 :     1. Changed interface to vectors and arrays in Basis to match
3020 :     (draft) Basis spec.
3021 :     2. Added signatures and implementations of slices according to
3022 :     Basis spec.
3023 :     3. Edited source code throughout the system to make it compile again
3024 :     under 1. and 2. (In some cases code had to be added to have it
3025 :     match the new signatures.)
3026 :     4. MLRISC should be backward-compatible: the copies of the originals
3027 :     of files that needed to change under 3. were retained, the .cm files
3028 :     check the compiler version number and use old versions when
3029 :     appropriate.
3030 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3031 :     dirstream -> string option (in accordance with Basis spec).
3032 :     6. When generating code that counts lines, ml-lex used function
3033 :     CharVector.foldli, taking advantage of its old interface.
3034 :     This has been replaced with the corresponding code from
3035 :     CharVectorSlice. (html-lex must be re-lexed!)
3036 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3037 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3038 :     8. Removed temporary additions (fromInternal, toInternal) from the
3039 :     (now obsolete) IntInf in smlnj-lib/Util.
3040 :     9. Cleaned up structure Byte.
3041 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3042 :     Cleaned/corrected implementation of Date.
3043 :     (Still need to check for correctness; implement better canonicalizeDate.)
3044 :     11. Added "scan" to signature IEEE_REAL.
3045 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3046 :     mod and rem when second operand is 2 (for parity checks).]
3047 :     13. Changed representation of type Time.time, using a single IntInf.int
3048 :     value counting microseconds. This considerably simplified the
3049 :     implementation of structure Time. We now support negative time
3050 :     values; scan and fromString handle signs.
3051 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3052 :     ArraySlice).

3057 :     Tag: blume-20030828-intinf
3058 :     Description:
3059 :    
3060 :     This is a major update which comes with a version number bump
3061 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3062 :     and an implementation of IntInf in the Basis.
3063 :    
3064 :     There are a fairly large number of related changes and updates throughout
3065 :     the system:
3066 :    
3067 :     Basis:
3068 :     - Implemented IntInf.
3069 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3070 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3071 : mblume 1347 - Added FixedInt as a synonym for Int32.
3072 :    
3073 :     compiler:
3074 :     * Added support for a built-in intinf type.
3075 :     - literals
3076 :     - pattern matching
3077 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3078 :     - overloading on literals and operations
3079 :    
3080 :     This required adding a primitive type intinf, some additional
3081 :     primops, and implementations for several non-trivial intinf
3082 :     operations in Core. (The intinf type is completely abstract
3083 :     to the compiler; all operations get delegated back to the Core.)
3084 :    
3085 :     * Intinf equality is handled by polyequal. However, the compiler
3086 :     does not print its usual warning in this case (since polyequal
3087 :     is the right thing to do there).
3088 :    
3089 :     * Improved the organization of structure InlineT.
3090 :    
3091 :     * A word about conversion primops:
3092 :     If conversions involving intinf do not cancel out during
3093 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3094 : mblume 1347 Since all core access must be resolved already during the FLINT
3095 :     translate phase, it would be too late a the time of CPS contract
3096 : mblume 1348 to add new Core calls. For this reason, conversion primops
3097 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3098 :     they are supposed to convert, and 2. the Core function that
3099 :     can help with this conversion if necessary. If CPS contract
3100 : mblume 1348 eliminates a primop, then the associated Core function becomes
3101 :     dead and goes away. Intinf conversion primops that do not get
3102 :     eliminated by CPS contract get rewritten into calls of their
3103 :     core functions by a separate, new phase.
3104 : mblume 1347
3105 :     interactive system:
3106 :     - Control.Print.intinfDepth controls max length of intinf constants
3107 :     being printed. (Analogous to Control.Print.stringDepth.)
3108 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3109 :     duplicates; replaced some of the code with code that makes better
3110 :     use of library functionality.
3111 :    
3112 :     CM:
3113 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3114 :     are no longer silent.
3115 :    
3116 :     CKIT:
3117 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3118 :     in favor of LargeInt -- which is now the same as IntInf.
3119 :     CKIT-knowledgable people should check whether this is what's
3120 :     intended and otherwise change things back to using Int32 or
3121 :     FixedInt.
3122 :    
3123 :     Throughout the code:
3124 : mblume 1348 Started using IntInf.int literals and built-in operations
3125 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3144 :     Tag: blume-20030811-windows
3145 :     Description:
3146 :    
3147 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3148 :    
3149 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3150 :    
3151 :     This patch restores SML/NJ's ability to run under win32. There are a
3152 :     number of changes, including fixes for several bugs that had gone
3153 :     unnoticed until now:
3154 :    
3155 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3156 :     trying to run the win32 version from within cygwin.)
3157 :    
3158 :     - There are a number of simple .bat scripts that substitute for their
3159 :     corresponding Unix shell-scripts. (See below.)
3160 :    
3161 :     - The internals of ml-build have been modified slightly. The main
3162 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3163 :     using OS.Process.system, the ML process delegates this task back
3164 :     to the script. Otherwise problems arise in mixed environments such
3165 :     as Cygwin where scripts look and work like Unix scripts, but
3166 :     where OS.Process.system cannot run them.
3167 :    
3168 :     - In CM, the srcpath pickler used native pathname syntax -- which
3169 :     is incorrect in the case of cross-compilation. The new pickle format
3170 :     is independent of platform-specific naming conventions.
3171 :    
3172 :     - Path configuration files (such as lib/pathconfig) can now choose
3173 :     between native and standard syntax. Placing a line of the form
3174 :    
3175 :     standard!
3176 :    
3177 :     into the file causes all subsequent paths to be interpreted using
3178 :     CM standard pathname syntax (= Unix conventions); a line
3179 :    
3180 :     native!
3181 :    
3182 :     switches back to native style. This was needed so that
3183 :     path config files can be written portably, see src/system/pathconfig.
3184 :    
3185 :     - Runtime system:
3186 :    
3187 :     - win32-filesys.c: get_file_time and set_file_time now
3188 :     access modification time, not creation time.
3189 :    
3190 :     - I/O code made aware of new array representation.
3191 :    
3192 :     - Bug fixes in X86.prim.masm.
3193 :    
3194 :     - src/system/makeml made aware of win32. (For use under cygwin
3195 :     and other Unix-environments for windows.)
3196 :    
3197 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3198 :     which caused BinIO.inputAll to fail consistently.
3199 :    
3200 :     .bat scripts:
3201 :    
3202 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3203 :    
3204 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3205 :     applications (sml, ml-yacc, ml-lex).
3206 :     - ml-build.bat: analogous to ml-build.
3207 :     - config\install.bat: Analogous to config/install.sh. This requires
3208 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3209 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3210 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3211 :     and the bootfile hierarchy must have been unpacked under
3212 :     sml.boot.x86-win32.
3213 :     The script is very primitive and does a poor job at error checking.
3214 :     It only installs the base system, ml-lex, and ml-yacc. No other
3215 :     libraries are being installed (i.e., you get only those that
3216 :     are part of the compiler.)
3217 :     - link-sml.bat: analogous to .link-sml, but not currently used
3218 :    
3219 :     Unrelated bug fixes:
3220 :    
3221 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3222 :     types.
3223 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3224 :     otherwise.)

3260 :     Tag: blume-20030517-absyn
3261 :     Description:
3262 :    
3263 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3264 :    
3265 :     This mainly affects the quality of error messages. However, some
3266 :     of the code is now more straightforward than before. (Treatment of
3267 :     the above four constructs in translate.sml is much simpler than
3268 :     the "macro-expansion" that was going on before. Plus, the mach-
3269 :     compiler no longer gets invoked just to be able to compile an
3270 :     if-expression.)
3271 :    
3272 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3273 :     interactive loop.

3279 :     Description:
3280 :    
3281 : blume 2155 Ported the runtime system to cygwin, which uses the unix
3282 : allenleung 1327 x86-unix bin files. Missing/buggy features:
3283 :    
3284 : blume 2155 o getnetbyname, getnetbyaddr: these functions seem to be missing in
3285 : allenleung 1327 the Cygwin library.
3286 :     o Ctrl-C handling may be flaky.
3287 :     o Windows system calls and Windows I/O are not supported.
3288 :    
3289 :     A new set of binfiles is located at:
3290 :    
3291 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3292 :    
3293 :     This is only needed for bootstrapping the cygwin version of smlnj.
3294 :     Other x86 versions can use the existing binfiles.

3319 :     Description:
3320 :    
3321 :     Fixed a serious bug in the rewrite code for FP spilling/reloading that
3322 :     sent the RA into an infinite loop when floating point registers get
3323 :     spilled. (Because of this bug, e.g., nucleic stopped compiling between
3324 :     110.37 and 110.38.)
3325 :     There was another set of potential problems related to the handling of
3326 :     MLRISC annotations (but those did not yet cause real problems, apparently).

3332 :     Description:
3333 :    
3334 :     Added a call of SrcPath.sync at the beginning of Parse.parse (in CM).
3335 :     This fixes the problem of CM getting confused by files that suddenly
3336 :     change their identity (e.g., by getting unlinked and recreated by some
3337 :     text editor such as vi). There might be a better/cheaper/cleaner way

3353 :    
3354 : blume 1282 In good old tradition, there has been a slight hiccup so that we have
3355 :     to patch 110.42 after the fact. The old release tag has been replaced
3356 :     (see below).
3357 :

3360 :     each other's way.
3361 :

3387 :     Description:
3388 :    
3389 :     Sml now senses the SMLNJ_HOME environment variable. If this is set,
3390 :     then the bin dir is assumed to be in $SMLNJ_HOME/bin and (unless
3391 :     CM_PATHCONFIG is also set), the path configuration file is assumed
3392 :     to be in $SMLNJ_HOME/lib/pathconfig. This way one can easily move
3393 :     the entire tree to some other place and everything will "just work".
3394 :

3396 :     variable.)

3448 :     idlbasis-devel branch so that we can test it.
3449 :    
3450 :     Another small change is that ppDec tries to give more information
3451 :     than just "<sig>" in the case of functors. However, this code is
3452 :     broken in some mysterious way if the functor's body's signature
3453 :     has not been declared by ascription but gets inferred from the
3454 :     implementation. This needs fixing...

3522 :     - Fixed messed-up controls priorities.
3523 :    
3524 :     * Removed again all the stuff from config/preloads that one wouldn't
3525 :     be able to preload at the time the initial heap image is built.
3526 :     (Many libraries, e.g., CML, do not exist yet at this time. The
3527 :     only libraries that can be preloaded via config/preloads are those
3528 :     that come bundled with the bootfiles.)

3553 :     Description:
3554 :    
3555 :     0. John Reppy made several modifications to the SML/NJ library.
3556 :     In particular, there is a shiny new controls-lib.cm.
3557 :    
3558 :     1. Pushed new controls interface through compiler so that everything
3559 :     compiles again.
3560 :    
3561 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3562 :     SML/NJ library (so that CML compiles again).
3563 :    
3564 :     3. Modified init scripts because XXX_DEFAULT environment variables
3565 :     are no longer with us. (Boot-time initialization is now done
3566 :     using the same environment variables that are also used for
3567 :     startup-time initialization of controls.)

3573 :     Description:
3574 :    
3575 :     All pseudo-ops emitted before the first segment declaration
3576 :     such as TEXT, DATA, and BSS directives are assumed to be global
3577 :     declarations and are emitted first in the assembly file. This is
3578 :     useful in a number of situations where one has pseudo-ops that are not
3579 :     specific to any segment, and also works around the constraint that one
3580 :     cannot have client pseudo-ops in the TEXT segment.
3581 :    
3582 :     Because no segment is associated with these declarations it is
3583 :     an error to allocate any space or objects before the first segment
3584 :     directive and an exception will be raised. However, we cannot make
3585 :     this check for client pseudo-ops.
3586 :    
3587 :     These top level declarations are a field in the CFG graph_info.
3588 :     In theory you can continue to add to this field after the CFG has been
3589 :     built -- provided you know what you are doing;-)

3612 :     Description:
3613 :    
3614 :     Applied the following bugfix provided by Emden Gansner:
3615 :    
3616 :     Output is corrupted when outputSubstr is used rather than output.
3617 :    
3618 : blume 2155 The problem occurs when a substring
3619 : blume 1189
3620 :     ss = (s, dataStart, dataLen)
3621 :    
3622 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3623 :     avail bytes of s, starting at index dataStart, are copied into the
3624 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3625 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3626 :     starting this copy at index dataStart+avail in s, the current code
3627 : blume 1189 starts the copy at index avail.
3628 :    
3629 :     Fix:
3630 :     In text-io-fn.sml, change line 695 from
3631 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3632 : blume 2155 to

3652 :     instruction's two results (without clumsily recomputing the remainder)
3653 :     directly where appropriate.
3654 :    
3655 :     Some more extensive power-of-two support was added to the x86 instruction
3656 :     selector (avoiding expensive divs, mods, and muls where they can be
3657 :     replaced with cheaper shifts and masks). However, this sort of thing
3658 :     ought to be done earlier, e.g., within the CPS optimizer so that
3659 :     all architectures benefit from it.
3660 :    
3661 :     The compiler compiles to a fixed point, but changes might be somewhat

3673 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3674 :     The problem was with quotient = 0, because that alone does not tell
3675 :     us which way the rounding went. One then has to look at whether
3676 :     remainder and divisor have the same sign... :(
3677 :    
3678 :     Anyway, I replaced the bootfiles with fresh ones...

3683 :     Tag: blume-20020329-inlprims
3684 :     Description:
3685 :    
3686 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
3687 :    
3688 :     Primops have changed. This means that the bin/boot-file formats have
3689 :     changed as well.
3690 :    
3691 :     To make sure that there is no confusion, I made a new version.
3692 :    
3693 :    
3694 :     CHANGES:
3695 :    
3696 :     * removed REMT from mltree (remainder should never overflow).
3697 :    
3698 :     * added primops to deal with divisions of all flavors to the frontend
3699 :    
3700 :     * handled these primops all the way through so they map to their respective
3701 :     MLRISC support
3702 :    
3703 :     * used these primops in the implementation of Int, Int32, Word, Word32
3704 :    
3705 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3706 :    
3707 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
3708 :    
3709 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3710 :     floating point
3711 :    
3712 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3713 :     and Real (but Real.abs maps to a separate floating-point-only primop)
3714 :    
3715 :    
3716 :     TODO items:
3717 :    
3718 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
3719 :     instructions because the machine instruction encoder cannot handle
3720 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
3721 :     REM in the first place, and REM is supported by the x86 machine coder.)
3722 :    
3723 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
3724 :     selection phase. (The two can be streamlined because the hardware
3725 :     delivers both quotient and remainder at the same time anyway.)
3726 :    
3727 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
3728 :     (Currently the behavior is inconsistent both across architectures and
3729 :     wrt. the draft Basis spec.)
3730 :    
3731 :     * Word8 should eventually be handled natively, too.
3732 :    
3733 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
3734 :     as if there currently is no execution path that could trigger it in
3735 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
3736 :     hold for things like multiplication and division.)

3741 :     Tag: blume-20020327-mlrisc-divisions
3742 :     Description:
3743 :    
3744 :     Added support for all four division operations (ML's div, mod, quot,
3745 :     and rem) to MLRISC. In the course of doing so, I also rationalized
3746 :     the naming (no more annoying switch-around of DIV and QUOT), by
3747 :     parameterizing the operation by div_rounding_mode (which can be either
3748 :     DIV_TO_ZERO or DIV_TO_NEGINF).
3749 :    
3750 :     The generic MLTreeGen functor takes care of compiling all four
3751 :     operations down to only round-to-zero div.
3752 :    
3753 :     Missing pieces:
3754 :    
3755 :     * Doing something smarter than relying on MLTreeGen on architectures
3756 :     like, e.g., the x86 where hardware division delivers both quotient and
3757 :     remainder at the same time. With this, the implementation of the
3758 :     round-to-neginf operations could be further streamlined.
3759 :    
3760 :     * Remove inlining support for div/mod/rem from the frontend and replace it
3761 :     with primops that get carried through to the backend. Do this for all
3762 :     int and word types.

3767 :     Tag: blume-20020325-divmod
3768 :     Description:
3769 :    
3770 :     I improved (hopefully without breaking them) the implementation of Int.div,
3771 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
3772 :     advantage of the following observations:
3773 :    
3774 :     Let q = x quot y r = x rem y
3775 :     d = x div y m = x mod y
3776 :    
3777 :     where "quot" is the round-to-zero version of integer division that
3778 :     hardware usually provides. Then we have:
3779 :    
3780 :     r = x - q * y where neither the * nor the - will overflow
3781 :     d = if q >= 0 orelse x = q * y then q else q - 1
3782 :     where neither the * nor the - will overflow
3783 :     m = if q >= 0 orelse r = 0 then r else r + y
3784 :     where the + will not overflow
3785 :    
3786 :     This results in substantial simplification of the generated code.
3787 :     The following table shows the number of CFG nodes and edges generated
3788 :     for
3789 :     fun f (x, y) = x OPER y
3790 :     (* with OPER \in div, mod, quot, rem *)
3791 :    
3792 :    
3793 :     OPER | nodes(old) | edges(old) | nodes(new) | edges(new)
3794 :     --------------------------------------------------------
3795 :     div | 24 | 39 | 12 | 16
3796 :     mod | 41 | 71 | 12 | 16
3797 :     quot | 8 | 10 | 8 | 10
3798 :     rem | 10 | 14 | 8 | 10

3831 :     Description:
3832 :    
3833 :     1. Changes to FLINT primops:
3834 :    
3835 :     (* make a call to a C-function;
3836 :     * The primop carries C function prototype information and specifies
3837 :     * which of its (ML-) arguments are floating point. C prototype
3838 :     * information is for use by the backend, ML information is for
3839 :     * use by the CPS converter. *)
3840 :     | RAW_CCALL of { c_proto: CTypes.c_proto,
3841 :     ml_args: ccall_type list,
3842 :     ml_res_opt: ccall_type option,
3843 :     reentrant : bool
3844 :     } option
3845 :     (* Allocate uninitialized storage on the heap.
3846 :     * The record is meant to hold short-lived C objects, i.e., they
3847 : blume 2155 * are not ML pointers. With the tag, the representation is
3848 : leunga 1174 * the same as RECORD with tag tag_raw32 (sz=4), or tag_fblock (sz=8)
3849 :     *)
3850 : blume 2155 | RAW_RECORD of {tag:bool,sz:int}
3851 : leunga 1174 and ccall_type = CCALL_INT32 | CCALL_REAL64 | CCALL_ML_PTR
3852 :    
3853 :     2. These CPS primops are now overloaded:
3854 :    
3855 :     rawload of {kind:numkind}
3856 :     rawstore of {kind:numkind}
3857 :    
3858 :     The one argument form is:
3859 :    
3860 :     rawload {kind} address
3861 :    
3862 :     The two argument form is:
3863 : blume 2155
3864 : leunga 1174 rawload {kind} [ml object, byte-offset]
3865 :    
3866 :     3. RAW_CCALL/RCC now takes two extra arguments:
3867 :    
3868 :     a. The first is whether the C call is reentrant, i.e., whether
3869 :     ML state should be saved and restored.
3870 :     b. The second argument is a string argument specifying the name of
3871 :     library and the C function.
3872 :    
3873 :     These things are currently not handled in the code generator, yet.
3874 :    
3875 :     4. In CProto,
3876 :    
3877 : blume 2155 An encoding type of "bool" means "ml object" and is mapped into
3878 :     C prototype of PTR. Note that "bool" is different than "string",
3879 : leunga 1174 even though "string" is also mapped into PTR, because "bool"
3880 :     is assigned an CPS type of BOGt, while "string" is assigned INT32t.
3881 :    
3882 :     5. Pickler/unpicker
3883 :    
3884 :     Changed to handle RAW_RECORD and newest RAW_CCALL
3885 :    
3886 :     6. MLRiscGen,
3887 :    
3888 :     1. Changed to handle the new rawload/rawstore/rawrecord operators.
3889 :     2. Code for handling C Calls has been moved to a new module CPSCCalls,
3890 :     in the file CodeGen/cpscompile/cps-c-calls.sml
3891 :    
3892 :     7. Added the conditional move operator
3893 :    
3894 :     condmove of branch
3895 :    
3896 : blume 2155 to cps. Generation of this is still buggy so it is currently
3897 : leunga 1174 disabled.

3903 : george 1168 Description:
3904 :    
3905 : blume 2155 Implemented the Ball-Larus branch prediction-heuristics, and
3906 : george 1168 incorporated graphical viewers for control flow graphs.
3907 :    
3908 : george 1171 Ball-Larus Heuristics:
3909 : george 1168 ---------------------
3910 :     See the file compiler/CodeGen/cpscompile/cpsBranchProb.sml.
3911 :    
3912 :     By design it uses the Dempster-Shafer theory for combining
3913 :     probabilities. For example, in the function:
3914 :    
3915 :     fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)
3916 :    
3917 :     the ball-larus heuristics predicts that the n=0 is unlikely
3918 :     (OH-heuristic), and the 'then' branch is unlikely because of the
3919 :     RH-heuristic -- giving the 'then' branch an even lower combined
3920 : george 1171 probability using the Dempster-Shafer theory.
3921 : george 1168
3922 :     Finally, John Reppy's loop analysis in MLRISC, further lowers the
3923 :     probability of the 'then' branch because of the loop in the else
3924 :     branch.
3925 :    
3926 :    
3927 :     Graphical Viewing:
3928 : blume 2155 ------------------
3929 : george 1168 I merely plugged in Allen's graphical viewers into the compiler. The
3930 :     additional code is not much. At the top level, saying:
3931 :    
3932 :     Control.MLRISC.getFlag "cfg-graphical-view" := true;
3933 :    
3934 :     will display the graphical view of the control flow graph just before
3935 :     back-patching. daVinci must be in your path for this to work. If
3936 :     daVinci is not available, then the default viewer can be changed
3937 :     using:
3938 :    
3939 :     Control.MLRISC.getString "viewer"
3940 :    
3941 :     which can be set to "dot" or "vcg" for the corresponding viewers. Of
3942 :     course, these viewers must be in your path.
3943 :    
3944 :     The above will display the compilation unit at the level of clusters,
3945 :     many of which are small, boring, and un-interesting. Also setting:
3946 :    
3947 :     Control.MLRISC.getInt "cfg-graphical-view_size"
3948 :    
3949 :     will display clusters that are larger than the value set by the above.

3974 :    
3975 : blume 2155 1. Recoded the buggy parts of x86-fp.
3976 : leunga 1156
3977 :     a. All the block reordering code has been removed.
3978 :     We now depend on the block placement phases to do this work.
3979 :    
3980 :     b. Critical edge splitting code has been simplified and moved into the
3981 :     CFG modules, as where they belong.
3982 :    
3983 :     Both of these were quite buggy and complex. The code is now much, much
3984 :     simpler.
3985 :    
3986 :     2. X86 backend.
3987 :    
3988 :     a. Added instructions for 64-bit support. Instruction selection for
3989 :     64-bit has not been committed, however, since that
3990 : blume 2155 requires changes to MLTREE which haven't been approved by
3991 : leunga 1156 Lal and John.
3992 :    
3993 : blume 2155 b. Added support for FUCOMI and FUCOMIP when generating code for
3994 : leunga 1156 PentiumPro and above. We only generate these instructions in
3995 :     the fast-fp mode.
3996 :    
3997 : blume 2155 c. Added cases for JP and JNP in X86FreqProps.
3998 :    
3999 : leunga 1156 3. CFG
4000 :    
4001 :     CFG now has a bunch of methods for edge splitting and merging.
4002 :    
4003 :     4. Machine description.
4004 :    
4005 :     John's simplification of MLTREE_BASIS.fcond broke a few machine
4006 :     description things:
4007 :    
4008 :     rtl-build.{sig,sml} and hppa.mdl fixed.
4009 :    
4010 : blume 2155 NOTE: the machine description stuff in the repository is still broken.

4012 :     changes to MLTREE.

4035 :     anywhere within big C types without resorting to outright "casts".
4036 :     (So far, functions such as C.rw/C.ro or C.Ptr.rw/C.Ptr.ro only let you
4037 :     modify the constness at the outermost level.)
4038 :     The implementation of "convert" is based on the idea of "witness"
4039 :     values -- values that are not used by the operation but whose types
4040 :     "testify" to their applicability. On the implementation side, "convert"

4068 :     ---------
4069 :    
4070 :     1. Factored out the recently-added Controls : CONTROLS stuff and put
4071 :     it into its own library $/controls-lib.cm. The source tree for
4072 :     this is under src/smlnj-lib/Controls.
4073 :    
4074 :     2. Changed the names of types and functions in this interface, so they
4075 :     make a bit more "sense":
4076 :    
4077 :     module -> registry
4078 :     'a registry -> 'a group
4079 :    
4080 :     3. The interface now deals in ref cells only. The getter/setter interface
4081 :     is (mostly) gone.
4082 :    
4083 :     4. Added a function that lets one register an already-existing ref cell.
4084 :    
4085 :     5. Made the corresponding modifications to the rest of the code so that
4086 :     everything compiles again.
4087 :    
4088 :     6. Changed the implementation of Controls.MLRISC back to something closer
4089 :     to the original. In particular, this module (and therefore MLRISC)
4090 :     does not depend on Controls. There now is some link-time code in
4091 :     int-sys.sml that registers the MLRISC controls with the Controls
4092 :     module.

4117 :    
4118 :     The problem was that the code generator did not generate any fp registers
4119 :     in this case, and the ra didn't know that it needed to run the X86FP phase to
4120 :     translate the pseudo fp instruction. This only happened with unary fp
4121 :     operators in certain situations.

4127 :     Description:
4128 :    
4129 :     1. Added _overload as a synonym for overload for backward compatibility.
4130 :     (Control.overloadKW must be true for either version to be accepted.)
4131 :    
4132 :     2. Fixed bug in install script that caused more things to be installed
4133 :     than what was requested in config/targets.
4134 :    
4135 :     3. Made CM aware of the (_)overload construct so that autoloading
4136 :     works.

4150 :     Description:
4151 :    
4152 :     Yet another version number bump (because of small changes to the
4153 :     binfile format). Version number is now 110.39.2. NEW BOOTFILES!
4154 :    
4155 :     Changes:
4156 :    
4157 :     The new pid generation scheme described a few weeks ago was overly
4158 :     complicated. I implemented a new mechanism that is simpler and
4159 :     provides a bit more "stability": Once CM has seen a compilation
4160 :     unit, it keeps its identity constant (as long as you do not delete
4161 :     those crucial CM/GUID/* files). This means that when you change
4162 : blume 1145 an interface, compile, then go back to the old interface, and
4163 : blume 1137 compile again, you arrive at the original pid.
4164 :    
4165 :     There now also is a mechanism that instructs CM to use the plain
4166 :     environment hash as a module's pid (effectively making its GUID
4167 :     the empty string). For this, "noguid" must be specified as an
4168 :     option to the .sml file in question within its .cm file.
4169 :     This is most useful for code that is being generated by tools such
4170 :     as ml-nlffigen (because during development programmers tend to
4171 :     erase the tool's entire output directory tree including CM's cached
4172 :     GUIDs). "noguid" is somewhat dangerous (since it can be used to locally
4173 :     revert to the old, broken behavior of SML/NJ, but in specific cases
4174 :     where there is no danger of interface confusion, its use is ok
4175 :     (I think).
4176 :    
4177 :     ml-nlffigen by default generates "noguid" annotations. They can be
4178 :     turned off by specifying -guid in its command line.

4193 :     Description:
4194 :    
4195 :     Tested the jump chain elimination on all architectures (except the
4196 :     hppa). This is on by default right now and is profitable for the
4197 :     alpha and x86, however, it may not be profitable for the sparc and ppc
4198 :     when compiling the compiler.
4199 :    
4200 : blume 2155 The gc test will typically jump to a label at the end of the cluster,
4201 :     where there is another jump to an external cluster containing the actual
4202 : george 1133 code to invoke gc. This is to allow factoring of common gc invocation
