254 : blume 2692 Date: 2007/06/06 21:45:00 CDT
255 :     Description:
256 :    
257 :     - Aaron: fixed a number of bugs in ml-ulex.
258 :     - Matthias:
259 :     - added CM control "cm.force-tools"; this is false by default;
260 :     when set to true, then tools like ml-yacc, ml-lex, ml-ulex, etc.
261 :     will be forced to run regardless of whether or not their targets
262 :     are up-to-date
263 :     - changed installer code so that config/install.sh will re-build
264 :     heap images for all tools even if those heap images already existed
265 :    
266 :     ----------------------------------------------------------------------
267 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
268 : blume 2688 Date: 2007/06/04 21:21:00 CDT
269 :     Description:
270 :    
271 :     After Aaron Turon's bug fix for ml-ulex (handling the ^ character
272 :     in legacy mode), re-ran the lexer generator on all lex input files
273 :     and committed the results.
274 :    
275 :     This should fix the problem with ckit and nlffi that was reported
276 :     by Vesa A. Norrman.
277 :

287 : dbm 2650 Name: Dave MacQueen (dbm@cs.uchicago.edu)
288 :     Date: 2007/05/31 14:55:00 CDT
289 :     Revision: 2650
290 :     Description:
291 :    
292 :     3rd merge of base from primop-branch-3 into the trunk.
293 :     Additional bug fixes included:
294 :    
295 :     * Timer.cpu_timer, etc. type printing corrected (by making
296 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
297 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by
298 :     Stefan Monnier)
299 :    
300 :     ----------------------------------------------------------------------
301 : blume 2645 Name: Matthias Blume (http://www.tti-c.org/blume/)
302 :     Date: 2007/05/31 11:40:00 CDT
303 :     Description:
304 :    
305 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
306 :    
307 :     Also, changed the handling of "no core access": When translate.sml
308 :     needs access to a core exception at a time when the core has not
309 :     been set up yet (this only happens when compiling system/smlnj/init/*),
310 :     then don't bother generating the corresponding tests.
311 :    
312 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
313 :     the exception. Unfortunately, that confuses the plambda type checker.
314 :     Moreover, it does not do any good, because at runtime we don't expect
315 :     such an exception to be ever raised. (The code in system/smlnj/init/*
316 :     has to be written very carefully with this in mind!)

319 : mrainey 2639 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
320 :     Date: 2007/05/29
321 :     Description:
322 :    
323 :     Added FSQRT instructions for the AMD64 code generator.
324 :    
325 :     ----------------------------------------------------------------------
326 : blume 2626 Name: Matthias Blume (http://www.tti-c.org/blume/)
327 :     Date: 2007/05/29 19:00:00 CDT
328 :     Description:
329 :    
330 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
331 :     with an explicit test for zero division. This should fixes several
332 :     regressions and makes it possible for downstream optimization phases
333 :     to treat these operations as "pure" when they are applied to unsigned
334 :     operands.
335 :    
336 :     ----------------------------------------------------------------------
337 : mrainey 2622 Name: Mike Rainey (http://www.cs.uchicago.edu/~mrainey)
338 :     Date: 2007/05/29
339 :     Description:
340 :    
341 :     Added the new MLRISC code generator for the AMD64. This version,
342 :     in contrast to the previous one, uses SSE registers and instructions
343 :     for all floating-point computations.
344 :

346 : jhr 2613 Name: John Reppy (http://www.cs.uchicago.edu/~jhr)
347 : jhr 2617 Date: 2007/05/29
348 : jhr 2613 Description:
349 :    
350 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
351 :     for bugs #1415 and #1416. We also now correctly handle format characters that
352 :     lie outside the specified set.

355 : blume 2610 Name: Matthias Blume (http://www.tti-c.org/blume/)
356 :     Date: 2007/05/23 22:30:00 CDT
357 :     Description:
358 :    
359 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
360 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
361 :    
362 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
363 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
364 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
365 :     while running CMB.make. The point is that the single symbol
366 :     NO_PLUGINS is definde in all three cases.)
367 :    
368 :     I changed the three locations within the sources that get compiled
369 :     during CMB.make where ml-yacc or ml-lex input is processed: When
370 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
371 :     is bypassed.
372 :    
373 :     When bootstrapping new versions of the compiler, there can be
374 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
375 :     are not available or otherwise not operational. In this case one can
376 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
377 :     do so, the following command should be issued at the interactive
378 :     prompt:
379 :    
380 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
381 :    
382 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
383 :     files that normally would be generated by ml-yacc and ml-lex.
384 :     (Copies of these files are in the repository.)

389 :     Revision: 2603
390 :     Description:
391 :    
392 :     2nd merge of base from primop-branch-3 into the trunk.
393 :     Additional bug fixes included:
394 :     Date.scan and Date.fromString fixed;
395 :     Overloading resolution fixed and some type printing problems corrected.

399 : blume 2589 Date: 2007/05/23 09:50:00 CDT
400 :     Description:
401 :    
402 :     Changed the installation mechanism for CM tool plugins. These are
403 :     just libaries and now get installed like ordinary libaries.
404 :    
405 :     There are now a number of new installation targets that give some
406 :     fine-grain control over what classes and suffixes are known, and what
407 :     they will map to.
408 :     See config/targets for details.
409 :    
410 :     The code that caused plugin installation as part of running a
411 :     tool's "build" script has been removed. (The build script is for
412 :     building, not for installing.)

415 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
416 : blume 2578 Date: 2007/05/22 11:50:00 CDT
417 :     Description:
418 :    
419 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
420 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
421 :     CM fail if a shell tool reports a non-success exit status. If
422 :     the control is set to true, then CM will press on after tool failures
423 :     in the event that the target files exist (even though they are
424 :     considered outdated). Turning the control to true can be useful for
425 :     bootstrapping.

433 :    
434 :     The name of several ml-lpt-lib modules has changed:
435 :     Repair => AntlrRepair
436 :     StreamPos => AntlrStreamPos
437 :     ErrHandlerFn => AntlrErrHandler
438 :     EBNF => AntlrEBNF
439 :    
440 :     The ml-antlr specification format has changed: declarations such as
441 :     %tokens and nonterminal definitions can occur *multiple* times in the
442 :     same specification. The semantics are such that each new declaration
443 :     extends the previous ones. This does not apply to %start or %name,
444 :     of course.
445 :    
446 :     Importing a grammar via %import now includes *all* declarations in from
447 :     the imported grammar, except for %name, %entry, and %start. Tokens
448 :     and nonterminals can be dropped using the new %dropping clause of the
449 :     %import directive; the separate %drop and %extend have been removed.
450 :    
451 :     We now allow optional type annotations on nonterminals, using the %nonterms
452 :     directive as in ml-yacc.
453 :    
454 :     The refcell construct is now implemented using SML's regular reference
455 :     cells, so the :== and !! notation has been deprecated.
456 :    
457 :     The ml-antlr tool now does much more checking of specifications, and
458 :     its error messages have been greatly improved. Error repair for
459 :     generated parsers has been completely rewritten, and is now both
460 :     much faster and more accurate.
461 :    
462 :     ml-ulex is now more lenient with escape codes (non-SML-standard
463 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
464 :     Also, character classes may now include a "-" character at the beginning
465 :     as is standard in most other regexp tools.
466 :    
467 :     All of these changes are documented in the user guide, which has
468 :     been updated and improved with this merge.

536 :    
537 :     More Basis fixes: The Char.fromString (etc.) functions did not handle

618 :     Date: 2007/02/26
619 :     Description:
620 :    
621 :     Added preliminary support in MLRISC for Staged Allocation, a technique
622 :     for specifying calling conventions (see
623 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
624 :     Initially, we plan to use this code to generate C calls for the AMD64.
625 :    
626 :     The staged allocation code base resides in MLRISC/staged-allocation,
627 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

633 :    
634 :     Bug fix: when SaveCState was called with two values to save, a subsequent
635 :     GC could cause the RestoreCState to fail because the saved state had been
636 :     promoted to tagless pair.

647 :    
648 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
649 :     of the range -128 ... 127. I've changed the code so that the range
650 :     check is disabled. Only the low order 8 bits of the immediate operand
651 : jhr 2342 are now significant.

691 :     Date: 2007/01/31
692 :     Description:
693 :    
694 :     Brought ml-lpt manual up-to-date with the code. Many minor
695 :     improvements to the tools, and a few minor bugfixes. Prepared
696 :     ml-lpt-lib for integration with new UTF8 structure. Changed
697 :     the interface for creating streams in ml-ulex (we now support
698 :     stream creation from several kinds of sources). Overall, the
699 :     tools are now quite stable, and their interfaces are unlikely to
700 :     change in a way that would break compatibility. More work,
701 :     however, is needed in the documentation.

705 : blume 2298 Date: 2007/02/01 10:05:00 CST
706 :     Description:
707 :    
708 :     Implemented library installer. Moved CM plugin code for
709 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
710 :     their respective trees. Implemented CM plugin for ml-ulex
711 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
712 :     and ml-antlr.
713 :    
714 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
715 :     CM tools. (It turns out to be too messy to do otherwise because
716 :     there is too much code that during installation relies on the presence
717 :     of these tools -- resulting in a tricky ordering problem.)

721 : blume 2277 Date: 2007/01/30 11:05:00 CST
722 :     Description:
723 :    
724 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
725 :     Modified CM's startup code to use shiftArgs as it processes
726 :     command line arguments. This way, the init code in each .sml-file
727 :     or library that is mentioned at the top level will see only
728 :     those arguments that have not yet been processed at this point.
729 :     In other words, the init code can "seize control" and process the
730 :     remaining command line.

744 :    
745 :     Added the UTF8 structure and signature from the Moby compiler to
746 :     the SML/NJ library (and the CML library). These modules will replace
747 :     the version in the ml-lpt-lib.

786 :     Description:
787 :    
788 :     Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to
789 :     get the c_cc termios data copied correctly. Also moved the allocation
790 :     of the string to avoid problems if it caused a GC.

796 :     Date: 2006/12/08 09:50:00 CST
797 :     Description:
798 :    
799 :     Added code to CM's "standard shell tool" implementation which
800 :     causes it to tolerate (with a warning) the situation where the shell
801 :     command fails (e.g., due to the shell command's non-existence)
802 :     as long as all target files exist.
803 :    
804 :     This makes it possible to, e.g., build ml-yacc from sources even if
805 :     svn checkout messed up the time stamps on files in such a way that
806 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
807 :     be needed to re-process yacc.grm, but obviously it might not yet be
808 :     available at that time.)

814 :    
815 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
816 :     recvVecFromNB' in the SOCKET signature. This error is actually
817 :     in the SML Basis specification too.

822 :     Description:

831 :    
832 :     Use Say.vsay for printing the "[autoloading]" message, so
833 :     #set CM.Control.verbose false (or -Ccm.verbose=false) can be used
834 :     to suppress them.

884 :     src/tools/TraceDebugProf -> trace-debug-profile
885 :    
886 :     In addition, there is also a new
887 :    
888 :     ml-lpt
889 :    
890 :     directory containing two new program generator tools: ml-ulex and
891 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
892 :     LL(k) parser generator). These tools are currently "beta-quality"
893 :    
894 :     The latest versios of the sources can now be obtained anonymously
895 :     via subversion. For this, it is useful to first check out
896 :    
897 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
898 :    
899 :     and put the resulting directory on your shell's PATH. This provides
900 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
901 :     and refresh-all.sh.
902 :    
903 :     To create a freshly checked-out copy of the sources, do
904 :    
905 :     checkout-all.sh [dir]
906 :    
907 :     where dir is the optional SML/NJ root directory (default is ".").
908 :    
909 :     This creates the above directory layout. Each subdirectory of
910 :     the root is under individual subversion control. The stat-all.sh
911 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
912 :     each of these subtrees.

916 : blume 2155 Date: 2006/11/02 12:20:00 CST
917 :     Description:
918 :    
919 :     Reorganized directory layout.
920 :    
921 :     This is a temporary solution, more reorganization is to come.
922 :    
923 :     The basic idea is to have a number of toplevel trees, each corresponding
924 :     to a well-defined part of the overall system. Each part can be
925 :     maintained individually, even in separate source repositories,
926 :     although currently we still serve everything out of the main
927 :     smlnj-gforge tree.
928 :    
929 :     Installer and and scripts have been updated to reflect the new
930 :     layout. The installer (base/src/system/smlnj/installer) is now
931 :     "scriptable" to avoid burning too much knowledge about the
932 :     layout into SML source code. The main script used by the installer
933 :     is in config/actions.
934 :    
935 :     The main change is that many of the subdirectories of what used to
936 :     be known as "src" have moved to the toplevel. The "src" directory
937 :     itself has moved down into a subtree called "base". (We may eventually
938 :     get rid of the extra level of indirection represented by "src".)
939 :    
940 :     The layout is now as follows:
941 :    
942 :     toplevel tree name | default repository
943 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
944 :     -------------------+----------------------------------------------------
945 :     config | $gf/config/trunk
946 :     |
947 :     base | $gf/sml/trunk
948 :     |
949 :     smlnj-lib | $gf/smlnj-lib/trunk
950 :     MLRISC | $gf/MLRISC/trunk
951 :     |
952 :     ml-yacc | $gf/ml-yacc/trunk
953 :     ml-lex | $gf/ml-lex/trunk
954 :     ml-burg | $gf/ml-burg/trunk
955 :     lexgen | $gf/lexgen/trunk
956 :     heap2asm | $gf/heap2asm/trunk
957 :     |
958 :     cml | $gf/cml/trunk
959 :     eXene | $gf/eXene/trunk
960 :     ckit | $gf/ckit/trunk
961 :     nlffi | $gf/nlffi/trunk
962 :     |
963 :     smlnj-c | $gf/smlnj-c/trunk
964 :    
965 :     In $gf/admin there are a few useful shell scripts for checking out
966 :     and maintaining the entire collection of trees:
967 :    
968 :     admin/checkout-all.sh [dir]
969 :     -- optionally creates dir and checks out all trees from their
970 :     default repositories; if dir is missing, checkout into .
971 :     admin/refresh-all.sh [dir]
972 :     -- looks at all trees (from the above list) in dir (default: .)
973 :     and runs "svn update" if the tree exists and is under
974 :     subversion control;
975 :     non-existing or non-subversion trees are skipped
976 :     admin/stat-all.sh [dir]
977 :     -- like refresh-all.sh, but runs "svn stat" instead

1220 :     Description:
1221 :    
1222 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1223 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1224 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1225 :     it. Instead, it has the status of "user code", so it should use
1226 :     $/basis.cm to refer to the Basis library. (At least that's true for
1227 :     the purpose of bootstrapping the previous change. In the future it
1228 :     might make sense to have versiontool.cm refer to
1229 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1230 :     compiler itself uses.)

1238 :     Tag: blume-22051115-libraries
1239 :     Description:
1240 :    
1241 :     This change affects the way the following libraries are tied into
1242 :     the system:
1243 :    
1244 :     $/basis.cm
1245 :     $/smlnj-lib.cm
1246 :     $/pp-lib.cm
1247 :     $/controls-lib.cm
1248 :     $/html-lib.cm
1249 :     $/ml-yacc-lib.cm
1250 :    
1251 :     These libraries are now internally (as seen from the source code
1252 :     of the implementation itself) known by the following names:
1253 :    
1254 :     $smlnj/basis/basis.cm
1255 :     $smlnj/smlnj-lib/smlnj-lib.cm
1256 :     $smlnj/smlnj-lib/pp-lib.cm
1257 :     $smlnj/smlnj-lib/controls-lib.cm
1258 :     $smlnj/smlnj-lib/html-lib.cm
1259 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1260 :    
1261 :     This makes it possible to work with code that requires different
1262 :     versions of these libraries, and which refers to these libraries using
1263 :     their "default" names (i.e., the first set of names above). In other
1264 :     words, one can un-define or re-define those default names without
1265 :     compromising the proper functioning of the compiler itself.
1266 :    
1267 :     A similar procedure had already been performed for several of the
1268 :     MLRISC libraries that are linked into the compiler. I did some
1269 :     cleanup on this code.
1270 :    
1271 :     A new file in the config directory (named extrapathconfig) is
1272 :     responsible for setting up path anchors that the compiler itself does
1273 :     not need, but that are typically required by user code.

1452 :     Tag: blume-20050516-redump-heap
1453 :     Description:
1454 :    
1455 :     Added mechanism for re-creating a heap file for the interactive system
1456 :     after configuration variables have been changed.
1457 :    
1458 :     CM.redump_heap : string -> unit
1459 :    
1460 :     This is much like SMLofNJ.exportML, but starting from the resulting
1461 : blume 2155 heap does not return to the caller of CM.redump_heap but
1462 : mblume 1792 restarts the interactive system from scratch. The original call of
1463 :     CM.redump_heap does not return but ends the interactive session.
1464 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1465 :    
1466 :     Internally, redump_heap winds the dynamic execution context back to
1467 :     the point where the original heap image was created and re-executes
1468 :     the heap image generation code in the boot code.

1584 :     Tag: blume-20050114-heap2exec
1585 :     Description:
1586 :    
1587 :     Implemented new (but still experimental) heap2exec facility. This is
1588 :     tested under Mac OS X and should work under Linux (will test shortly).
1589 :     It will probably also work on the Sparc (will test some time later).
1590 :    
1591 :     - removed old "HACKED_STANDALONE" hack from runtime
1592 :    
1593 :     To be able to test this, uncomment the request for "heap2asm" in
1594 :     config/targets prior to installation. (Notice that this is different
1595 :     from "heap2exec" mentioned below. Not a typo.)
1596 :    
1597 :     To perform an actual test, run the command
1598 :    
1599 :     $ bin/heap2exec heapfile execfile
1600 :    
1601 :     (You can put heap2exec on your shell's path.)
1602 :    
1603 :     For example, run
1604 :    
1605 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1606 :    
1607 :     This will create a standalone executable called "mly" which you can
1608 :     then invoke directly as a command.

1635 :    
1636 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1637 :     (On the Mac, it is big-endian. And that's currently our only
1638 :     PPC platform.)

1655 :    
1656 : blume 2155 The Unix I/O library of SML/NJ on cygwin does not understand

1705 :    
1706 :     Hacked some of the scripts (in particular: the installer) to cope with
1707 :     spaces in filenames a bit better. But beware: the current "solution"
1708 :     is likely still full of bugs and inherently incomplete. (We need to
1709 :     do away with those shell scripts for a comprehensive solution.)

1753 :     Tag: blume-20041124-position
1754 :     Description:
1755 :    
1756 :     The compiler can now be compiled in a mode that makes structure Position
1757 :     equal to Int64. The default, however, is unchanged (Position = Int31)
1758 :     for the time being.
1759 :    
1760 :     To enable 64-bit positions, use the following procedure:
1761 :    
1762 :     1. Start sml
1763 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1764 :     3. Type
1765 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1766 :     4. Run CMB.make() as usual.
1767 :    
1768 :     This is barely tested. The only test so far was a little SML program
1769 :     counting the number of characters in an 8-gigabyte file by
1770 :     reading it character-by-character. That test was successful.
1771 :    
1772 :     In support of 64-bit positions, a number of new functions have been
1773 :     added to the runtime system.

1817 :     The date string is generated at bootstrap time (during makeml).
1818 :    
1819 :     - In a previous commit, fixed a minor issue with how polyequal is being
1820 :     translated. In particular, the code now "looks through" abstractions.
1821 :     This results in slightly fewer polyEqual warnings and hopefully slightly
1822 :     more efficient code. Important examples for where this matters are
1823 :     the new int64 and word64 types.

1838 :     Description:
1839 :    
1840 :     All the pieces of Word64 are now there, with the exception of the
1841 :     conversions from and to LargeWord. (Eventually these need to be identities,
1842 :     but for the time being they don't even make sense because LargeWord is
1843 :     32-bit wide.)
1844 :    
1845 :     Also started to add similar support for Int64, but major pieces of that
1846 :     are still missing.

1851 :     Tag: blume-20041111-word64
1852 :     Description:
1853 :    
1854 :     Structure Word64 is now (almost) complete, word literals and patterns
1855 :     seem to work. There are a few odd pieces missing. In particular,
1856 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1857 :     at the moment.
1858 :    
1859 :     Making Word64 official would mean that LargeWord becomes Word64. But
1860 :     this requires extreme care because most word-word conversions have to
1861 :     go through LargeWord, so making a mistake means loss of efficiency or
1862 :     worse. Eventually there will be a solution similar to (but actually
1863 :     simpler than) what I did with IntInf.

1900 :     normally does not have to be edited to reflect a version change.
1901 :    
1902 :     (As a result, a version change can be done by just editing

1943 :     Tag: blume-20041020-standalone-backtrace
1944 :     Description:
1945 :    
1946 :     Added a mechanism for getting back-trace information from standalone
1947 :     programs. Here is how it works:
1948 :    
1949 :     1. The part of the program from which you want to get backtrace
1950 :     information (usually the whole program) should be wrapped with
1951 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
1952 :     main program could be modified from something like
1953 :    
1954 :     fun main (pgm, args) = ...
1955 :    
1956 :     to
1957 :    
1958 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1959 :    
1960 :     2. To be able to access BackTrace.monitor, you have to add
1961 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
1962 :     main function.
1963 :    
1964 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1965 :     CM might have created in the past for your project).
1966 :    
1967 :     4. Build the system using this command line:
1968 :    
1969 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1970 :     myprog.cm MyProg.main myprog
1971 :    
1972 :     instead of the usual
1973 :    
1974 :     ml-build myprog.cm MyProg.main myprog
1975 :    
1976 :     I changed a library name:
1977 :    
1978 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1979 :    
1980 :     New libraries:
1981 :    
1982 :     $smlnj-tdp/back-trace.cm
1983 :     -- when loaded causes the back-trace plugin to be installed
1984 :     $smlnj-tdp/coverage.cm
1985 :     -- when loaded causes the coverage plugin to be installed

2001 :     Description:
2002 :    
2003 :     * Test coverage tool added!
2004 :     * Further reorganization of tracing-, debugging-, and profiling support:
2005 :    
2006 :     - moved original BTImp -- now called BackTrace -- into a separate
2007 :     library called $/trace-debug-profile.cm
2008 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2009 :     - only the instrumentation mechanism is now left in the compiler proper
2010 :     - BackTrace module is a plugin which is NOT plugged in by default
2011 :     - Coverage module is another such plugin
2012 :    
2013 :     To get the benefits of any of these plugin modules, the code in
2014 :     question must be compiled with tdp instrumentation turned on. This
2015 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2016 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2017 :    
2018 :     Plugins are selected at link time. (Pre-compiled instrumented code
2019 :     can be re-loaded with different plugins in effect.) When an
2020 :     instrumented module is linked, whatever plugins are at that time
2021 :     enabled will come into effect for that module.
2022 :    
2023 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2024 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2025 :     To enable the coverage plugin, load the same library and invoke
2026 :     Coverage.install().
2027 :    
2028 :     Back-traces are generated automatically on uncaught exceptions and
2029 :     when the code in question explicitly invokes BackTrace.trigger().
2030 :    
2031 :     Coverage (and execution frequency-) information must be queried
2032 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2086 :

2088 :     is supposed to accept a tool argument called "source", but this did
2089 :     not work because of the clash with the keyword.

2098 :

2100 :     hash table implementation
2101 :     - threw out most of the pathnames stuff, as it was not used anyway
2102 :     - simplified tokentable implementation

2132 :     Description:
2133 :    
2134 :     * Moved the "version" magic into its own little library under
2135 : mblume 1672 src/system/smlnj/internal. This avoids expensive reconstruction of
2136 :     a stable src/compiler/core.cm.
2137 : mblume 1639

2139 :     structure SMLNJVersion.
2140 : mblume 1639
2141 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2142 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2143 :     Also, loading the versiontool does not work when rebuilding the system
2144 :     because CM is not properly initialized at that time.

2149 :     Tag: blume-20040929-autoversion
2150 :     Description:
2151 :    
2152 :     Implemented some CM magic to have
2153 :     file src/compiler/TopLevel/main/version.sml
2154 :     generated automagically.
2155 :     The version is taken from two files: config/version and config/release.
2156 :     The first is expected to contain a two-part version number such as 110.49.
2157 :     The second should contain a single number, but it may be missing.
2158 :    
2159 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2160 :     time the version tool is loaded (which is the first time you say CMB.make),
2161 :     then the tool will increment the value stored in config/release every
2162 :     time CMB.make is invoked.
2163 :    
2164 :     The binfile format is now insensitive to anything beyond the first
2165 :     two components of a version number, so bumping the release does not render
2166 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2167 :     during development without invalidating existing binfiles.
2168 :    
2169 :     In any case, every CMB.make updates the date information in version.sml.
2170 :     (This is the date that is printed in the banner.)

2183 :     Tag: blume-20040927-controls
2184 :     Description:
2185 :    
2186 :     Added two pieces of functionality to the Controls interface:
2187 :    
2188 :     1. val save'restore: 'a control -> unit -> unit
2189 :    
2190 :     grabs the current value of the control in stage 1 and restores it
2191 :     in stage 2.
2192 :    
2193 :     2. val set' : 'a control * 'a -> unit -> unit
2194 :    
2195 :     stores the given value into the control in stage 2 (i.e., delayed)
2196 :     but does all error checking in stage 1.
2197 :     (This is for string controls that need to do parse their argument --
2198 :     something that might fail. In some cases, notably in CM, one
2199 :     already knows the intended argument but wants to delay the actual
2200 :     assignment until a time when error recovery would be more difficult.)
2201 :    
2202 :     Changed the handling of controls in tool arguments to classes "sml" and
2203 :     "lazysml":
2204 :     - use Controls.save'restore as a more robust way of restoring the
2205 :     old value (in particular: without having to re-parse the string)
2206 :     - use controls to handle the "overload" keyword in the init group
2207 :     (I believe this change actually fixes a long-standing obscure bug.)

2212 :     Tag: blume-20040927-lazysml
2213 :     Description:
2214 :    
2215 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2216 :     difference to "sml" is that compilation is done with Control.lazysml
2217 :     set to true. A source of class "lazysml" is automatically recognized
2218 :     by a file name suffix of ".lml".
2219 :    
2220 :     In addition to the above feature, the original class "sml" now also
2221 :     supports a tool argument "lazy" which has the same effect. As a
2222 :     result, the following three lines are equivalent:
2223 :    
2224 :     foo.sml : lazysml
2225 :     foo.sml : sml (lazy)
2226 :     foo.sml (lazy)
2227 :    
2228 :     The setting goes into effect both during parsing and during
2229 :     compilation. The original setting is restored right after parsing and
2230 :     after compilation, respectively.
2231 :    
2232 :     In addition to all the above, there is also a general mechanism to set
2233 :     ANY of the "controls" that are available at the command line via
2234 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2235 :     apply as well. (In fact, "lazy" is implemented as a special case of
2236 :     the general mechanism.)
2237 :    
2238 :     The .cm file syntax uses a new keyword tool argument called "with".
2239 :     There are several ways of indicating the desired settings:
2240 :    
2241 :     foo.sml (with:parser.quotations=true)
2242 :     foo.sml (with:(name:parser.quotations value:true))
2243 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2244 :     foo.sml (with:(name1=value1 name2=value2 ...))
2245 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2246 :    
2247 :     etc.
2248 :    
2249 :     Another possible abbreviation is to leave out the =v or value:v part
2250 :     if the name refers to a boolean control (in which case the value is
2251 :     taken to be true). Thus, one could get lazy sml also by saying:
2252 :    
2253 :     foo.sml (with:parser.lazy-keyword=true)
2254 :     foo.sml (with:parser.lazy-keyword)
2255 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2256 :     foo.sml (with:(name:parser.lazy-keyword))

2483 :    
2484 :     Gearing up towards 110.47...
2485 :    
2486 :     - various minor bugfixes to ml-nlffigen
2487 :     - a beginning of a manual for nlffi
2488 :    
2489 :     - eliminated 'export name=value' in config/install.sh as this does
2490 :     not work with certain versions of /bin/sh
2491 :     (Thanks to David King at Motorola for catching this.)
2492 :    
2493 :     - several bugfixes provided or suggested by David Hansel at Reactive Systems:
2494 :     - added a test for tm==NULL to gmtime.c and localtime.c
2495 :     - applied patch for incorrect GetFileTime under win32
2496 :     - toSeconds -> toMilliseconds in Win32/win32-process.sml

2502 :     Description:
2503 :    
2504 :     - Fixed minor issue in ml-nlffigen: Now generate structure T_foo
2505 :     for a typedef to an incomplete type, but leave out the "typ" member.
2506 :     (This is just for consistency.)
2507 :     - Started to produce what is supposed to become better (i.e., comprehensive)
2508 :     documentation of what ml-nlffigen does and produces.

2514 :     Description:
2515 :    
2516 :     Added C_UNION to c-calls/c-types.sml and updated the machinery
2517 :     (ml-nlffigen, cproto.sml) that conveys C function interface
2518 :     information to the code generator.
2519 :    
2520 :     However, the actual architecture-specific implementation of function
2521 :     arguments and results that are C unions is still not implemented.

2553 :     Description:
2554 :    
2555 :     - use paramAlloc to report c-calls with too many arguments
2556 :     (for PPC version where parameter area is pre-allocated)
2557 :     - added ccall_maxargspace to machspec (to implement the above)
2558 :     - made "make" commend in CM's "make" tool configurable
2559 :     - added option (default: on) for passing the name of the SML/NJ's "bin"
2560 :     directory to "make"; the call looks like this:
2561 :    
2562 :     make <options> SMLNJ_BINDIR=<dir> <target>
2563 :    
2564 :     This can be used by the Makefile to, e.g., pick the "right" version
2565 :     of ml-nlffigen.
2566 :     - minor code tweaks

2573 :    
2574 :     NLFFI under Mac OS X now working (sort of). This is largely untested,
2575 :     though.
2576 :    
2577 :     Note: 1. You have to make a new, clean build of the runtime system.
2578 :     2. There are new BOOTFILES, you have to use them!
2579 :     (Doing the bootstrap process yourself would be *very* painful!
2580 :     If you absolutely have to do it, build the system under
2581 :     a different architecture and then cross-compile.)
2582 :    
2583 :     Version bumped to 110.46.1 to account for runtime data format changes.

2607 :     Tag: blume-20040617-timer-unix
2608 :     Description:
2609 :    
2610 :     Changed the interface of structures Timer and Unix to match the most
2611 :     recent Basis spec.
2612 :    
2613 :     In the case of Unix there still seems to be an open/weird issue:
2614 :    
2615 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2616 :     fresh streams whenever they are called -- as opposed to have them
2617 :     return the same stream every time. This design is supposed to
2618 :     prevent space leaks caused by proc values hanging on to streams.
2619 :    
2620 :     The reap function, on the other hand, is supposed to close the
2621 :     streams. This cannot be done without having a handle on the
2622 :     stream in proc after all...
2623 :    
2624 :     I took the liberty to implement the following stopgap solution:
2625 :    
2626 :     The proc value hangs on to the most recently created stream(s).
2627 :     Reap closes those. If either or both of the two streams hadn't
2628 :     been created at all yet, then reap will close the corresponding
2629 :     file descriptors directly.
2630 :    
2631 :     PS: I don't understand the original space leak argument anymore. If
2632 :     a proc hangs on to the imperative stream, then I/O operations on those
2633 :     will advance the state of the cached stream and avoid the space leak.

2646 :     Tag: blume-20040525-group-owner
2647 :     Description:
2648 :    
2649 :     CM now ignores (but still accepts) the "owner" information in group
2650 :     descriptions. The owner of a group is its next enclosing
2651 :     library. Each group must have a unique owner. (There is a virtual
2652 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2653 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2654 :     and CM would check that such a declaration is correct. The new scheme
2655 :     is to have CM check that for each group there is precisely one owning
2656 :     library.
2657 :    
2658 :     The advantage of the new scheme is that the programmer no longer needs
2659 :     to maintain the somewhat annoying owner information. The downside is
2660 :     that CM cannot enforce the ownership rule across multiple runs of
2661 :     CM.make. Fortunately, enclosing the same group in two different
2662 :     libraries A and B which are not part of the same program does not
2663 :     cause real problems.

2672 :     slipped into win32-process.c which prevented the runtime from being
2673 :     compiled correctly.)
2674 :    
2675 :     Also, included a minor addition to ml-build.bat analogous to what was
2676 :     done in blume-20040519-ml-build.

2682 :     Description:
2683 :    
2684 :     Arranged for ml-build to clean up after itself a little bit better.
2685 :     The script generates a temporary SML source file and compiles it using
2686 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
2687 :     gets rid of those at the end, so they don't accumulate under .cm.
2688 :    
2689 :     This required a minor change to install.sh because the name of the
2690 :     metadata directory (default: .cm) is actually configurable at
2691 :     installation time.

2706 :     Description:
2707 :    
2708 :     Added previously missing support for many socket-related functions
2709 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
2710 :     for the voluminous patch!
2711 :    
2712 :     (I have not tested this patch under win32 yet.)
2713 :    
2714 : mblume 1490 Here is David's e-mail:
2715 :    
2716 :     Hi,
2717 :    
2718 :     Attached to this email you find a diff against sml/nj 110.45
2719 :     that will enable socket support under Windows.
2720 :    
2721 :     To apply the patch (using unix or cygwin)
2722 :     1) gunzip runtime.diff.gz
2723 :     2) "cd" into "src/runtime" in the source tree of a fresh
2724 :     110.45 installation.
2725 :     3) patch -p 1 < [your/path/to]runtime.diff
2726 :    
2727 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
2728 :     I only ran a few tests for basic socket client functionality
2729 :     (which worked fine). Especially the functions that use ioctl
2730 : mblume 1490 are not tested at all and might not work (see below).
2731 :    
2732 :     I implemented this since we want to move to a newer version of sml/nj
2733 :     but need socket support in order to use it. This is the first time I
2734 :     even had a look at the sml/nj source, so please review my changes
2735 :     before making this part of the distribution! Here are a few issues
2736 : blume 2155 that I think might be better for someone to solve who is more
2737 : mblume 1490 familiar with the sml/nj source (and socket programming):
2738 :    
2739 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2740 :     exception since I could not figure out what the windows equivalent
2741 :     of these functions is
2742 :    
2743 :     - In sockets-osdep.h there are a some #include statements that are
2744 :     only used in a few files that include sockets-osdep.h
2745 :    
2746 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2747 :     does not process its return value since I don't know how to
2748 :     report an error upwards.
2749 :    
2750 :     - It would probably be good to have a call to WSACleanup() when
2751 : blume 2155 the library is unloaded (if there is such a possibility).
2752 : mblume 1490 Otherwise I think Windows will take care of this automatically
2753 :     when the process finishes.
2754 :    
2755 :     - I used ioctlsocket() as a replacement for ioctl() but I have
2756 :     no idea if that is actually the proper replacement on Windows.
2757 :    
2758 :     - All these issues are marked in the code by "FIXME" comments.
2759 :    
2760 : blume 2155 We use sml/nj extensively in our products and are quite happy
2761 :     with it. I hope this contribution will help you.
2762 : mblume 1490
2763 :     Keep up the good work!

2877 :     Fixed problem with installer script (unix only) where bin/ml-yacc and
2878 :     friends pointed (via symlinks) to absolute locations instead of just
2879 :     .run-sml. This was reported by Vesa A Norrman.

2928 :     Description:
2929 :    
2930 :     Eliminated the "dont_move_libraries" directive in config/targets.
2931 :     (The mechanism was broken and could not be fixed easily. Moreover,
2932 :     there does not seem to be any reason not to move all libraries into
2933 :     lib during installation. I originally implemented this directive as a
2934 :     backward-compatibility feature when I first introduced the new CM.
2935 :     Now that things have been stable for a long time and going back to the
2936 :     old CM is not an option, there is no reason to keep it around.)

2985 :     Tag: blume-20030926-ppautoload
2986 :     Description:
2987 :    
2988 :     I modified the read-eval-print loop so that the autoloader gets
2989 :     invoked whenever the prettyprinter tries to look up a symbol that
2990 :     is not currently defined in the toplevel environment but which
2991 :     appears in CM's autoload registry. As a result, we see far fewer of
2992 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
2993 :    
2994 :     In addition to this I tried to clean up some pieces of the Basis
2995 :     implementation (e.g., Socket, Word8Array) in order to prevent other
2996 :     instances of these ?.Foo.Bar.xxx names from being printed.
2997 :    
2998 :     The mechanism that picks names for types still needs some work, though.
2999 :     (Right now it seems that if there is a type A.t which is defined to
3000 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3001 :     "?.B.u" although the perhaps more sensible solution would be to use
3002 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3003 :     a chain of DEFtycs not farther than there are corresponding toplevel
3004 :     names in the current environment.)

3010 :     Description:
3011 :    
3012 :     Another installer tweak: All the ML code for the installer is now
3013 :     compiled during CMB.make and put into a little library called
3014 :     $smlnj/installer.cm. The installation then simply invokes
3015 :    
3016 :     sml -m $smlnj/installer.cm
3017 :    
3018 :     and everything happens automagically.
3019 :    
3020 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3021 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3022 :     and BINDIR.
3023 :    
3024 :     The new scheme guarantees that the ML code responsible for the installation
3025 :     is in sync with the APIs of the main system. Also, the installer is
3026 :     somewhat faster because the installer script is precompiled.

3033 :    
3034 :     Added a signature SYNCHRONOUS_SOCKET to basis.cm. This is like SOCKET
3035 :     but excludes all non-blocking operations. Defined SOCKET (in Basis)
3036 :     and CML_SOCKET in terms of SYNCHRONOUS_SOCKET. Removed superfluous
3037 :     implementations of non-blocking operations from CML's Socket
3038 :     structure.

3043 :     Tag: blume-20030924-sockets
3044 :     Description:
3045 :    
3046 :     1. Fixed SOCKET API and implementation to match Basis spec.
3047 :     This required changing the internal representation of sockets to one
3048 :     that remembers (for each socket file descriptor) whether it is currently
3049 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3050 :     call is made only if the state actually needs to change).
3051 :    
3052 :     2. OS-specific details of sockets were moved into separate files, thus
3053 :     making it possible to unify the bulk of the socket implementations
3054 :     between Unix and Win32.
3055 :    
3056 :     3. CML's socket API changed accordingly.
3057 :     (Note that we need to remove non-blocking functions from this API
3058 :     since they are redundant in the case of CML!)
3059 :    
3060 :     4. CML's socket implementation now makes use of non-blocking functions
3061 :     provided by Basis, thus removing all OS-dependent code from this part
3062 :     of CML.
3063 :    
3064 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3176 :     Tag: blume-20030909-installer
3177 :     Description:
3178 :    
3179 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3180 :     Modified config/install.bat to take advantage of it. Also modified
3181 :     config/install.sh (and called it config/new-install.sh) to take advantage
3182 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3183 :     independent.)
3184 :    
3185 :     The installer can now install everything under Win32
3186 :     as well as under *nix as long as it compiles.
3187 :    
3188 :     Other changes:
3189 :    
3190 :     - made CML compile again under Win32
3191 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3192 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3193 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3194 :     same as type int; under Win32 it isn't
3195 :     - fixed some slice-related problems in the win32-specific parts of CML
3196 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3197 :     (under Win32, the volume name is case-insensitive, and the
3198 :     OS.Path code compares volume names for equality)

3215 : mblume 1350 Description:
3216 :    
3217 :     1. Changed interface to vectors and arrays in Basis to match
3218 :     (draft) Basis spec.
3219 :     2. Added signatures and implementations of slices according to
3220 :     Basis spec.
3221 :     3. Edited source code throughout the system to make it compile again
3222 :     under 1. and 2. (In some cases code had to be added to have it
3223 :     match the new signatures.)
3224 :     4. MLRISC should be backward-compatible: the copies of the originals
3225 :     of files that needed to change under 3. were retained, the .cm files
3226 :     check the compiler version number and use old versions when
3227 :     appropriate.
3228 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3229 :     dirstream -> string option (in accordance with Basis spec).
3230 :     6. When generating code that counts lines, ml-lex used function
3231 :     CharVector.foldli, taking advantage of its old interface.
3232 :     This has been replaced with the corresponding code from
3233 :     CharVectorSlice. (html-lex must be re-lexed!)
3234 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3235 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3236 :     8. Removed temporary additions (fromInternal, toInternal) from the
3237 :     (now obsolete) IntInf in smlnj-lib/Util.
3238 :     9. Cleaned up structure Byte.
3239 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3240 :     Cleaned/corrected implementation of Date.
3241 :     (Still need to check for correctness; implement better canonicalizeDate.)
3242 :     11. Added "scan" to signature IEEE_REAL.
3243 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3244 :     mod and rem when second operand is 2 (for parity checks).]
3245 :     13. Changed representation of type Time.time, using a single IntInf.int
3246 :     value counting microseconds. This considerably simplified the
3247 :     implementation of structure Time. We now support negative time
3248 :     values; scan and fromString handle signs.
3249 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3250 :     ArraySlice).

3262 :     There are a fairly large number of related changes and updates throughout
3263 :     the system:
3264 :    
3265 :     Basis:
3266 :     - Implemented IntInf.
3267 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3268 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3269 : mblume 1347 - Added FixedInt as a synonym for Int32.
3270 :    
3271 :     compiler:
3272 :     * Added support for a built-in intinf type.
3273 :     - literals
3274 :     - pattern matching
3275 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3276 :     - overloading on literals and operations
3277 :    
3278 :     This required adding a primitive type intinf, some additional
3279 :     primops, and implementations for several non-trivial intinf
3280 :     operations in Core. (The intinf type is completely abstract
3281 :     to the compiler; all operations get delegated back to the Core.)
3282 :    
3283 :     * Intinf equality is handled by polyequal. However, the compiler
3284 :     does not print its usual warning in this case (since polyequal
3285 :     is the right thing to do there).
3286 :    
3287 :     * Improved the organization of structure InlineT.
3288 :    
3289 :     * A word about conversion primops:
3290 :     If conversions involving intinf do not cancel out during
3291 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3292 : mblume 1347 Since all core access must be resolved already during the FLINT
3293 :     translate phase, it would be too late a the time of CPS contract
3294 : mblume 1348 to add new Core calls. For this reason, conversion primops
3295 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3296 :     they are supposed to convert, and 2. the Core function that
3297 :     can help with this conversion if necessary. If CPS contract
3298 : mblume 1348 eliminates a primop, then the associated Core function becomes
3299 :     dead and goes away. Intinf conversion primops that do not get
3300 :     eliminated by CPS contract get rewritten into calls of their
3301 :     core functions by a separate, new phase.
3302 : mblume 1347
3303 :     interactive system:
3304 :     - Control.Print.intinfDepth controls max length of intinf constants
3305 :     being printed. (Analogous to Control.Print.stringDepth.)
3306 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3307 :     duplicates; replaced some of the code with code that makes better
3308 :     use of library functionality.
3309 :    
3310 :     CM:
3311 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3312 :     are no longer silent.
3313 :    
3314 :     CKIT:
3315 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3316 :     in favor of LargeInt -- which is now the same as IntInf.
3317 :     CKIT-knowledgable people should check whether this is what's
3318 :     intended and otherwise change things back to using Int32 or
3319 :     FixedInt.
3320 :    
3321 :     Throughout the code:
3322 : mblume 1348 Started using IntInf.int literals and built-in operations
3323 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3333 :     These changes involve replacement of the emulated old prettyprinter

3341 : mblume 1342 Date: 2003/08/11 15:45:00 CDT
3342 :     Tag: blume-20030811-windows
3343 :     Description:
3344 :    
3345 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3346 :    
3347 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3348 :    
3349 :     This patch restores SML/NJ's ability to run under win32. There are a
3350 :     number of changes, including fixes for several bugs that had gone
3351 :     unnoticed until now:
3352 :    
3353 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3354 :     trying to run the win32 version from within cygwin.)
3355 :    
3356 :     - There are a number of simple .bat scripts that substitute for their
3357 :     corresponding Unix shell-scripts. (See below.)
3358 :    
3359 :     - The internals of ml-build have been modified slightly. The main
3360 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3361 :     using OS.Process.system, the ML process delegates this task back
3362 :     to the script. Otherwise problems arise in mixed environments such
3363 :     as Cygwin where scripts look and work like Unix scripts, but
3364 :     where OS.Process.system cannot run them.
3365 :    
3366 :     - In CM, the srcpath pickler used native pathname syntax -- which
3367 :     is incorrect in the case of cross-compilation. The new pickle format
3368 :     is independent of platform-specific naming conventions.
3369 :    
3370 :     - Path configuration files (such as lib/pathconfig) can now choose
3371 :     between native and standard syntax. Placing a line of the form
3372 :    
3373 :     standard!
3374 :    
3375 :     into the file causes all subsequent paths to be interpreted using
3376 :     CM standard pathname syntax (= Unix conventions); a line
3377 :    
3378 :     native!
3379 :    
3380 :     switches back to native style. This was needed so that
3381 :     path config files can be written portably, see src/system/pathconfig.
3382 :    
3383 :     - Runtime system:
3384 :    
3385 :     - win32-filesys.c: get_file_time and set_file_time now
3386 :     access modification time, not creation time.
3387 :    
3388 :     - I/O code made aware of new array representation.
3389 :    
3390 :     - Bug fixes in X86.prim.masm.
3391 :    
3392 :     - src/system/makeml made aware of win32. (For use under cygwin
3393 :     and other Unix-environments for windows.)
3394 :    
3395 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3396 :     which caused BinIO.inputAll to fail consistently.
3397 :    
3398 :     .bat scripts:
3399 :    
3400 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3401 :    
3402 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3403 :     applications (sml, ml-yacc, ml-lex).
3404 :     - ml-build.bat: analogous to ml-build.
3405 :     - config\install.bat: Analogous to config/install.sh. This requires
3406 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3407 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3408 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3409 :     and the bootfile hierarchy must have been unpacked under
3410 :     sml.boot.x86-win32.
3411 :     The script is very primitive and does a poor job at error checking.
3412 :     It only installs the base system, ml-lex, and ml-yacc. No other
3413 :     libraries are being installed (i.e., you get only those that
3414 :     are part of the compiler.)
3415 :     - link-sml.bat: analogous to .link-sml, but not currently used
3416 :    
3417 :     Unrelated bug fixes:
3418 :    
3419 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3420 :     types.
3421 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3422 :     otherwise.)

3446 :     Description:
3447 :    
3448 :     Two changes:
3449 :    
3450 :     1. Added a flag for controlling whether non-exhaustive bindings will
3451 :     be treated as errors (default is false).
3452 :     2. Cleaned up the *entire* source tree so that CMB.make goes through

3459 :     Description:
3460 :    
3461 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3462 :    
3463 :     This mainly affects the quality of error messages. However, some
3464 :     of the code is now more straightforward than before. (Treatment of
3465 :     the above four constructs in translate.sml is much simpler than
3466 :     the "macro-expansion" that was going on before. Plus, the mach-
3467 :     compiler no longer gets invoked just to be able to compile an
3468 :     if-expression.)
3469 :    
3470 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3471 :     interactive loop.

3477 :     Description:
3478 :    
3479 : blume 2155 Ported the runtime system to cygwin, which uses the unix

3481 :    
3482 : blume 2155 o getnetbyname, getnetbyaddr: these functions seem to be missing in
3483 : allenleung 1327 the Cygwin library.
3484 :     o Ctrl-C handling may be flaky.
3485 :     o Windows system calls and Windows I/O are not supported.
3486 :    
3487 :     A new set of binfiles is located at:
3488 :    
3489 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3490 :    
3491 :     This is only needed for bootstrapping the cygwin version of smlnj.

3533 :     This fixes the problem of CM getting confused by files that suddenly
3534 :     change their identity (e.g., by getting unlinked and recreated by some
3535 :     text editor such as vi). There might be a better/cheaper/cleaner way

3715 :    
3716 :     - Added ControlUtil structure to control-lib.cm.
3717 :     - Use it throughout.
3718 :     - Used Controls facility to define MLRISC controls (as opposed to
3719 :     registering MLRISC control ref cells with Controls after the fact)
3720 :     - Fixed messed-up controls priorities.
3721 :    
3722 :     * Removed again all the stuff from config/preloads that one wouldn't
3723 :     be able to preload at the time the initial heap image is built.
3724 :     (Many libraries, e.g., CML, do not exist yet at this time. The
3725 :     only libraries that can be preloaded via config/preloads are those
3726 :     that come bundled with the bootfiles.)

3751 :     Description:
3752 :    
3753 :     0. John Reppy made several modifications to the SML/NJ library.
3754 :     In particular, there is a shiny new controls-lib.cm.
3755 :    
3756 :     1. Pushed new controls interface through compiler so that everything
3757 :     compiles again.
3758 :    
3759 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
3760 :     SML/NJ library (so that CML compiles again).
3761 :    
3762 :     3. Modified init scripts because XXX_DEFAULT environment variables
3763 :     are no longer with us. (Boot-time initialization is now done
3764 :     using the same environment variables that are also used for
3765 :     startup-time initialization of controls.)

3771 :     Description:
3772 :    
3773 :     All pseudo-ops emitted before the first segment declaration
3774 :     such as TEXT, DATA, and BSS directives are assumed to be global
3775 :     declarations and are emitted first in the assembly file. This is
3776 :     useful in a number of situations where one has pseudo-ops that are not
3777 :     specific to any segment, and also works around the constraint that one
3778 :     cannot have client pseudo-ops in the TEXT segment.
3779 :    
3780 :     Because no segment is associated with these declarations it is
3781 :     an error to allocate any space or objects before the first segment
3782 :     directive and an exception will be raised. However, we cannot make
3783 :     this check for client pseudo-ops.
3784 :    
3785 :     These top level declarations are a field in the CFG graph_info.
3786 :     In theory you can continue to add to this field after the CFG has been
3787 :     built -- provided you know what you are doing;-)

3793 :     Description:
3794 :    
3795 :     A few minor bugfixes:
3796 :    
3797 :     - Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
3798 :     (Bogus printouts for redefined bindings still occur. Compiler
3799 :     bug should no longer occur now. We need to redo the prettyprinter
3800 :     from scratch.)
3801 :    
3802 :     - CM pathname printer now also adds escape sequences for ( and )
3803 :    
3804 :     - commend and docu fixes for ml-nlffi

3809 :     Tag: blume-20020510-erg-textio
3810 :     Description:
3811 :    
3812 :     Applied the following bugfix provided by Emden Gansner:
3813 :    
3814 :     Output is corrupted when outputSubstr is used rather than output.
3815 :    
3816 : blume 2155 The problem occurs when a substring
3817 : blume 1189
3818 :     ss = (s, dataStart, dataLen)
3819 :    
3820 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
3821 :     avail bytes of s, starting at index dataStart, are copied into the
3822 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
3823 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
3824 :     starting this copy at index dataStart+avail in s, the current code
3825 : blume 1189 starts the copy at index avail.
3826 :    
3827 :     Fix:
3828 :     In text-io-fn.sml, change line 695 from
3829 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3830 : blume 2155 to
3831 : blume 1189 val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

3847 :     Description:
3848 :    
3849 :     Added full support for div/mod/rem/quot on the x86, using the machine
3850 :     instruction's two results (without clumsily recomputing the remainder)
3851 :     directly where appropriate.
3852 :    
3853 :     Some more extensive power-of-two support was added to the x86 instruction
3854 :     selector (avoiding expensive divs, mods, and muls where they can be
3855 :     replaced with cheaper shifts and masks). However, this sort of thing
3856 :     ought to be done earlier, e.g., within the CPS optimizer so that
3857 :     all architectures benefit from it.
3858 :    
3859 :     The compiler compiles to a fixed point, but changes might be somewhat
3860 :     fragile nevertheless. Please, report any strange things that you might
3861 :     see wrt. div/mod/quot/rem...

3867 :     Description:
3868 :    
3869 :     Fixed my broken div/mod logic. Unfortunately, this means that the
3870 :     inline code for div/mod now has one more comparison than before.
3871 :     Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3872 :     The problem was with quotient = 0, because that alone does not tell
3873 :     us which way the rounding went. One then has to look at whether
3874 :     remainder and divisor have the same sign... :(
3875 :

3882 :     Description:
3883 :    
3884 :     NEW BOOTFILES!!! Version number bumped to 110.39.3.
3885 :    
3886 :     Primops have changed. This means that the bin/boot-file formats have
3887 :     changed as well.
3888 :    
3889 :     To make sure that there is no confusion, I made a new version.
3890 :    
3891 :    
3892 :     CHANGES:
3893 :    
3894 :     * removed REMT from mltree (remainder should never overflow).
3895 :    
3896 :     * added primops to deal with divisions of all flavors to the frontend
3897 :    
3898 :     * handled these primops all the way through so they map to their respective
3899 :     MLRISC support
3900 :    
3901 :     * used these primops in the implementation of Int, Int32, Word, Word32
3902 :    
3903 :     * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3904 :    
3905 :     * parameterized INLMIN, INLMAX, and INLABS by a numkind
3906 :    
3907 :     * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3908 :     floating point
3909 :    
3910 :     * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3911 :     and Real (but Real.abs maps to a separate floating-point-only primop)
3912 :    
3913 :    
3914 :     TODO items:
3915 :    
3916 :     * Hacked Alpha32 instruction selection, disabling the selection of REMx
3917 :     instructions because the machine instruction encoder cannot handle
3918 :     them. (Hppa, PPC, and Sparc instruction selection did not handle
3919 :     REM in the first place, and REM is supported by the x86 machine coder.)
3920 :    
3921 :     * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
3922 :     selection phase. (The two can be streamlined because the hardware
3923 :     delivers both quotient and remainder at the same time anyway.)
3924 :    
3925 :     * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
3926 :     (Currently the behavior is inconsistent both across architectures and
3927 :     wrt. the draft Basis spec.)
3928 :    
3929 :     * Word8 should eventually be handled natively, too.
3930 :    
3931 :     * There seems to be one serious bug in mltree-gen.sml. It appears, though,
3932 :     as if there currently is no execution path that could trigger it in
3933 :     SML/NJ. (The assumptions underlying functions arith and promotable do not
3934 :     hold for things like multiplication and division.)

3939 :     Tag: blume-20020327-mlrisc-divisions
3940 :     Description:
3941 :    
3942 :     Added support for all four division operations (ML's div, mod, quot,
3943 :     and rem) to MLRISC. In the course of doing so, I also rationalized
3944 :     the naming (no more annoying switch-around of DIV and QUOT), by
3945 :     parameterizing the operation by div_rounding_mode (which can be either
3946 :     DIV_TO_ZERO or DIV_TO_NEGINF).
3947 :    
3948 :     The generic MLTreeGen functor takes care of compiling all four
3949 :     operations down to only round-to-zero div.
3950 :    
3951 :     Missing pieces:
3952 :    
3953 :     * Doing something smarter than relying on MLTreeGen on architectures
3954 :     like, e.g., the x86 where hardware division delivers both quotient and
3955 :     remainder at the same time. With this, the implementation of the
3956 :     round-to-neginf operations could be further streamlined.
3957 :    
3958 :     * Remove inlining support for div/mod/rem from the frontend and replace it
3959 :     with primops that get carried through to the backend. Do this for all
3960 :     int and word types.

3965 :     Tag: blume-20020325-divmod
3966 :     Description:
3967 :    
3968 :     I improved (hopefully without breaking them) the implementation of Int.div,
3969 :     Int.mod, and Int.rem. For this, the code in translate.sml now takes
3970 :     advantage of the following observations:
3971 :    
3972 :     Let q = x quot y r = x rem y
3973 :     d = x div y m = x mod y
3974 :    
3975 :     where "quot" is the round-to-zero version of integer division that
3976 :     hardware usually provides. Then we have:
3977 :    
3978 :     r = x - q * y where neither the * nor the - will overflow
3979 :     d = if q >= 0 orelse x = q * y then q else q - 1
3980 :     where neither the * nor the - will overflow
3981 :     m = if q >= 0 orelse r = 0 then r else r + y
3982 :     where the + will not overflow
3983 :    
3984 :     This results in substantial simplification of the generated code.
3985 :     The following table shows the number of CFG nodes and edges generated
3986 :     for
3987 :     fun f (x, y) = x OPER y
3988 :     (* with OPER \in div, mod, quot, rem *)
3989 :    
3990 :    
3991 :     OPER | nodes(old) | edges(old) | nodes(new) | edges(new)
3992 :     --------------------------------------------------------
3993 :     div | 24 | 39 | 12 | 16
3994 :     mod | 41 | 71 | 12 | 16

4030 :    
4031 :     1. Changes to FLINT primops:
4032 :    
4033 :     (* make a call to a C-function;
4034 :     * The primop carries C function prototype information and specifies
4035 :     * which of its (ML-) arguments are floating point. C prototype
4036 :     * information is for use by the backend, ML information is for
4037 :     * use by the CPS converter. *)
4038 :     | RAW_CCALL of { c_proto: CTypes.c_proto,
4039 :     ml_args: ccall_type list,
4040 :     ml_res_opt: ccall_type option,
4041 :     reentrant : bool
4042 :     } option
4043 :     (* Allocate uninitialized storage on the heap.
4044 :     * The record is meant to hold short-lived C objects, i.e., they
4045 : blume 2155 * are not ML pointers. With the tag, the representation is
4046 : leunga 1174 * the same as RECORD with tag tag_raw32 (sz=4), or tag_fblock (sz=8)
4047 :     *)
4048 : blume 2155 | RAW_RECORD of {tag:bool,sz:int}
4049 : leunga 1174 and ccall_type = CCALL_INT32 | CCALL_REAL64 | CCALL_ML_PTR
4050 :    
4051 :     2. These CPS primops are now overloaded:
4052 :    
4053 :     rawload of {kind:numkind}
4054 :     rawstore of {kind:numkind}
4055 :    
4056 :     The one argument form is:
4057 :    
4058 :     rawload {kind} address
4059 :    
4060 :     The two argument form is:
4061 : blume 2155
4062 : leunga 1174 rawload {kind} [ml object, byte-offset]
4063 :    
4064 :     3. RAW_CCALL/RCC now takes two extra arguments:
4065 :    
4066 :     a. The first is whether the C call is reentrant, i.e., whether
4067 :     ML state should be saved and restored.
4068 :     b. The second argument is a string argument specifying the name of
4069 :     library and the C function.
4070 :    
4071 :     These things are currently not handled in the code generator, yet.
4072 :    
4073 :     4. In CProto,
4074 :    
4075 : blume 2155 An encoding type of "bool" means "ml object" and is mapped into
4076 :     C prototype of PTR. Note that "bool" is different than "string",
4077 : leunga 1174 even though "string" is also mapped into PTR, because "bool"
4078 :     is assigned an CPS type of BOGt, while "string" is assigned INT32t.
4079 :    
4080 :     5. Pickler/unpicker
4081 :    
4082 :     Changed to handle RAW_RECORD and newest RAW_CCALL
4083 :    
4084 :     6. MLRiscGen,
4085 :    
4086 :     1. Changed to handle the new rawload/rawstore/rawrecord operators.
4087 :     2. Code for handling C Calls has been moved to a new module CPSCCalls,
4088 :     in the file CodeGen/cpscompile/cps-c-calls.sml
4089 :    
4090 :     7. Added the conditional move operator
4091 :    
4092 :     condmove of branch
4093 :    
4094 : blume 2155 to cps. Generation of this is still buggy so it is currently

4101 : george 1168 Description:
4102 :    
4103 : blume 2155 Implemented the Ball-Larus branch prediction-heuristics, and
4104 : george 1168 incorporated graphical viewers for control flow graphs.
4105 :    
4106 : george 1171 Ball-Larus Heuristics:
4107 : george 1168 ---------------------
4108 :     See the file compiler/CodeGen/cpscompile/cpsBranchProb.sml.
4109 :    
4110 :     By design it uses the Dempster-Shafer theory for combining
4111 :     probabilities. For example, in the function:
4112 :    
4113 :     fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)
4114 :    
4115 :     the ball-larus heuristics predicts that the n=0 is unlikely
4116 :     (OH-heuristic), and the 'then' branch is unlikely because of the
4117 :     RH-heuristic -- giving the 'then' branch an even lower combined
4118 : george 1171 probability using the Dempster-Shafer theory.
4119 : george 1168
4120 :     Finally, John Reppy's loop analysis in MLRISC, further lowers the
4121 :     probability of the 'then' branch because of the loop in the else
4122 :     branch.
4123 :    
4124 :    
4125 :     Graphical Viewing:
4126 : blume 2155 ------------------
4127 : george 1168 I merely plugged in Allen's graphical viewers into the compiler. The
4128 :     additional code is not much. At the top level, saying:
4129 :    
4130 :     Control.MLRISC.getFlag "cfg-graphical-view" := true;
4131 :    
4132 :     will display the graphical view of the control flow graph just before
4133 :     back-patching. daVinci must be in your path for this to work. If
4134 :     daVinci is not available, then the default viewer can be changed
4135 :     using:
4136 :    
4137 :     Control.MLRISC.getString "viewer"
4138 :    
4139 :     which can be set to "dot" or "vcg" for the corresponding viewers. Of
4140 :     course, these viewers must be in your path.
4141 :    
4142 :     The above will display the compilation unit at the level of clusters,
4143 :     many of which are small, boring, and un-interesting. Also setting:
4144 :    
4145 :     Control.MLRISC.getInt "cfg-graphical-view_size"
4146 :    
4147 :     will display clusters that are larger than the value set by the above.

4171 :     Description:
4172 :    
4173 : blume 2155 1. Recoded the buggy parts of x86-fp.
4174 : leunga 1156
4175 :     a. All the block reordering code has been removed.
4176 :     We now depend on the block placement phases to do this work.
4177 :    
4178 :     b. Critical edge splitting code has been simplified and moved into the
4179 :     CFG modules, as where they belong.
4180 :    
4181 :     Both of these were quite buggy and complex. The code is now much, much
4182 :     simpler.
4183 :    
4184 :     2. X86 backend.
4185 :    
4186 :     a. Added instructions for 64-bit support. Instruction selection for
4187 :     64-bit has not been committed, however, since that
4188 : blume 2155 requires changes to MLTREE which haven't been approved by
4189 : leunga 1156 Lal and John.
4190 :    
4191 : blume 2155 b. Added support for FUCOMI and FUCOMIP when generating code for
