384 :
385 :			- Aaron: fixed a number of bugs in ml-ulex.
386 :			- Matthias:
387 :			- added CM control "cm.force-tools"; this is false by default;

417 :			Revision: 2650
418 :			Description:
419 :
420 :			3rd merge of base from primop-branch-3 into the trunk.
421 :			Additional bug fixes included:
422 :
423 :			* Timer.cpu_timer, etc. type printing corrected (by making
424 :			Timer have opaque sig constraint in basis/Implementation/timer.sml)
425 :			* Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by

429 :	blume	2645	Name: Matthias Blume (http://www.tti-c.org/blume/)
430 :			Date: 2007/05/31 11:40:00 CDT
431 :			Description:
432 :
433 :			Fixed some bugs in new Div code in FLINT/trans/translate.sml.
434 :
435 :			Also, changed the handling of "no core access": When translate.sml
436 :			needs access to a core exception at a time when the core has not
437 :			been set up yet (this only happens when compiling system/smlnj/init/*),
438 :			then don't bother generating the corresponding tests.
439 :
440 :	dbm	2650	The old scheme was to generate a bogus value to be used in place of
441 :			the exception. Unfortunately, that confuses the plambda type checker.
442 :			Moreover, it does not do any good, because at runtime we don't expect
443 :			such an exception to be ever raised. (The code in system/smlnj/init/*
444 :			has to be written very carefully with this in mind!)

456 :			Description:
457 :
458 :			FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
459 :			with an explicit test for zero division. This should fixes several
460 :			regressions and makes it possible for downstream optimization phases
461 :			to treat these operations as "pure" when they are applied to unsigned

485 :			Description:
486 :
487 :			CMB (and CM) now automatically defines the CM "preprocessor" symbol
488 :			NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
489 :
490 :			(In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
491 :			CM_SLAVE_MODE is defined in attached slaves while running CM.make
492 :			or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
493 :			while running CMB.make. The point is that the single symbol
494 :			NO_PLUGINS is definde in all three cases.)
495 :
496 :			I changed the three locations within the sources that get compiled
497 :			during CMB.make where ml-yacc or ml-lex input is processed: When
498 :			NO_PLUGINS defined, then the use of the mlyacc and mllex tools
499 :			is bypassed.
500 :
501 :			When bootstrapping new versions of the compiler, there can be
502 :			situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
503 :			are not available or otherwise not operational. In this case one can
504 :			manually define the NO_PLUGINS symbol prior to running CMB.make(). To
505 :			do so, the following command should be issued at the interactive
506 :			prompt:
507 :
508 :			#set (CMB.symval "NO_PLUGINS") (SOME 1);
509 :
510 :			A CMB.make with NO_PLUGINS defined relies on the existence of the
511 :			files that normally would be generated by ml-yacc and ml-lex.
512 :			(Copies of these files are in the repository.)

547 :			Added a boolean control named cm.tolerate-tool-failures (env. variable
548 :			name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
549 :			CM fail if a shell tool reports a non-success exit status. If
550 :			the control is set to true, then CM will press on after tool failures
551 :			in the event that the target files exist (even though they are

558 :			Description:
559 :
560 :			Merge of ml-lpt revisions for 110.64.
561 :
562 :			The name of several ml-lpt-lib modules has changed:
563 :			Repair => AntlrRepair
564 :			StreamPos => AntlrStreamPos
565 :			ErrHandlerFn => AntlrErrHandler
566 :			EBNF => AntlrEBNF
567 :
568 :			The ml-antlr specification format has changed: declarations such as
569 :			%tokens and nonterminal definitions can occur *multiple* times in the
570 :			same specification. The semantics are such that each new declaration
571 :			extends the previous ones. This does not apply to %start or %name,
572 :			of course.
573 :
574 :			Importing a grammar via %import now includes *all* declarations in from
575 :			the imported grammar, except for %name, %entry, and %start. Tokens
576 :			and nonterminals can be dropped using the new %dropping clause of the
577 :			%import directive; the separate %drop and %extend have been removed.
578 :
579 :			We now allow optional type annotations on nonterminals, using the %nonterms
580 :			directive as in ml-yacc.
581 :
582 :			The refcell construct is now implemented using SML's regular reference
583 :			cells, so the :== and !! notation has been deprecated.
584 :
585 :			The ml-antlr tool now does much more checking of specifications, and
586 :			its error messages have been greatly improved. Error repair for
587 :			generated parsers has been completely rewritten, and is now both
588 :			much faster and more accurate.
589 :
590 :			ml-ulex is now more lenient with escape codes (non-SML-standard
591 :			escape codes are now interpreted literally, so e.g. \| denotes "|").
592 :			Also, character classes may now include a "-" character at the beginning
593 :			as is standard in most other regexp tools.
594 :
595 :			All of these changes are documented in the user guide, which has
596 :			been updated and improved with this merge.

841 :
842 :			For ml-yacc and ml-lex we continue to have permanently "plugged-in"
843 :			CM tools. (It turns out to be too messy to do otherwise because
844 :			there is too much code that during installation relies on the presence

852 :			Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
853 :			Modified CM's startup code to use shiftArgs as it processes
854 :			command line arguments. This way, the init code in each .sml-file
855 :			or library that is mentioned at the top level will see only
856 :			those arguments that have not yet been processed at this point.
857 :			In other words, the init code can "seize control" and process the

925 :			Description:
926 :
927 :			Added code to CM's "standard shell tool" implementation which
928 :			causes it to tolerate (with a warning) the situation where the shell
929 :			command fails (e.g., due to the shell command's non-existence)
930 :			as long as all target files exist.
931 :
932 :			This makes it possible to, e.g., build ml-yacc from sources even if
933 :			svn checkout messed up the time stamps on files in such a way that
934 :			yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
935 :			be needed to re-process yacc.grm, but obviously it might not yet be
936 :			available at that time.)

975 :			Tag: release-110.60
976 :			Description:
977 :
978 :			New working release (110.60). NEW BOOTFILES!
979 :
980 :			This is the first subversion-hosted release. There are also changes
981 :			to the directory layout. Here is a table:
982 :
983 :			(All pathnames are relative to the SML/NJ "root" directory.)
984 :
985 :			config -> config
986 :
987 :			src/cm -> base/cm
988 :			src/compiler -> base/compiler
989 :			src/runtime -> base/runtime
990 :			src/system -> base/system
991 :
992 :			src/cm/pgraph -> pgraph
993 :
994 :			src/READMES -> base/READMES
995 :			src/$notefile -> base/NOTES/$notefile
996 :			for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
997 :			MACOSXINSTALL WININSTALL
998 :
999 :			src/smlnj-lib -> smlnj-lib
1000 :			src/MLRISC -> MLRISC
1001 :			ckit -> ckit
1002 :			src/cml -> cml
1003 :			src/eXene -> eXene
1004 :			src/heap2asm -> heap2asm
1005 :			src/lexgen -> lexgen
1006 :			src/ml-burg -> ml-burg
1007 :			src/ml-lex -> ml-lex
1008 :			src/ml-yacc -> ml-yacc
1009 :			src/ml-nlffi-lib -> nlffi/lib
1010 :			src/ml-nlffigen -> nlffi/gen
1011 :			src/smlnj-c -> smlnj-c
1012 :			src/tools/TraceDebugProf -> trace-debug-profile
1013 :
1014 :			In addition, there is also a new
1015 :
1016 :			ml-lpt
1017 :
1018 :			directory containing two new program generator tools: ml-ulex and
1019 :			ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1020 :			LL(k) parser generator). These tools are currently "beta-quality"
1021 :
1022 :			The latest versios of the sources can now be obtained anonymously
1023 :			via subversion. For this, it is useful to first check out
1024 :
1025 :			svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1026 :
1027 :			and put the resulting directory on your shell's PATH. This provides
1028 :			access to three shell scripts: checkout-all.sh, stat-all.sh,
1029 :			and refresh-all.sh.
1030 :
1031 :			To create a freshly checked-out copy of the sources, do
1032 :
1033 :			checkout-all.sh [dir]
1034 :
1035 :			where dir is the optional SML/NJ root directory (default is ".").
1036 :
1037 :			This creates the above directory layout. Each subdirectory of
1038 :			the root is under individual subversion control. The stat-all.sh
1039 :			and refresh-al.sh scripts apply "svn stat" or "svn update" to
1040 :			each of these subtrees.

1043 :			Name: Matthias Blume (http://www.tti-c.org/blume/)
1044 :	blume	2155	Date: 2006/11/02 12:20:00 CST
1045 :			Description:
1046 :
1047 :			Reorganized directory layout.
1048 :
1049 :			This is a temporary solution, more reorganization is to come.
1050 :
1051 :			The basic idea is to have a number of toplevel trees, each corresponding
1052 :			to a well-defined part of the overall system. Each part can be
1053 :			maintained individually, even in separate source repositories,
1054 :			although currently we still serve everything out of the main
1055 :			smlnj-gforge tree.
1056 :
1057 :			Installer and and scripts have been updated to reflect the new
1058 :			layout. The installer (base/src/system/smlnj/installer) is now
1059 :			"scriptable" to avoid burning too much knowledge about the
1060 :			layout into SML source code. The main script used by the installer
1061 :			is in config/actions.
1062 :
1063 :			The main change is that many of the subdirectories of what used to
1064 :			be known as "src" have moved to the toplevel. The "src" directory
1065 :			itself has moved down into a subtree called "base". (We may eventually
1066 :			get rid of the extra level of indirection represented by "src".)
1067 :
1068 :			The layout is now as follows:
1069 :
1070 :			toplevel tree name | default repository
1071 :			| (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1072 :			-------------------+----------------------------------------------------
1073 :			config | $gf/config/trunk
1074 :			|
1075 :			base | $gf/sml/trunk
1076 :			|
1077 :			smlnj-lib | $gf/smlnj-lib/trunk
1078 :			MLRISC | $gf/MLRISC/trunk
1079 :			|
1080 :			ml-yacc | $gf/ml-yacc/trunk
1081 :			ml-lex | $gf/ml-lex/trunk
1082 :			ml-burg | $gf/ml-burg/trunk
1083 :			lexgen | $gf/lexgen/trunk
1084 :			heap2asm | $gf/heap2asm/trunk
1085 :			|
1086 :			cml | $gf/cml/trunk
1087 :			eXene | $gf/eXene/trunk
1088 :			ckit | $gf/ckit/trunk
1089 :			nlffi | $gf/nlffi/trunk
1090 :			|
1091 :			smlnj-c | $gf/smlnj-c/trunk
1092 :
1093 :			In $gf/admin there are a few useful shell scripts for checking out
1094 :			and maintaining the entire collection of trees:
1095 :
1096 :			admin/checkout-all.sh [dir]
1097 :			-- optionally creates dir and checks out all trees from their
1098 :			default repositories; if dir is missing, checkout into .
1099 :			admin/refresh-all.sh [dir]
1100 :			-- looks at all trees (from the above list) in dir (default: .)
1101 :			and runs "svn update" if the tree exists and is under
1102 :			subversion control;
1103 :			non-existing or non-subversion trees are skipped
1104 :			admin/stat-all.sh [dir]
1105 :			-- like refresh-all.sh, but runs "svn stat" instead

1348 :			Description:
1349 :
1350 :			Reversed change to src/system/smlnj/internals/versiontool.cm. This
1351 :			file gets loaded as a tool -- by the equivalent of CM.make during the
1352 :			run of CMB.make. Thus, CMB's path configuration is meaningless for
1353 :			it. Instead, it has the status of "user code", so it should use
1354 :			$/basis.cm to refer to the Basis library. (At least that's true for
1355 :			the purpose of bootstrapping the previous change. In the future it
1356 :			might make sense to have versiontool.cm refer to
1357 :			$smlnj/basis/basis.cm, i.e., the version of the Basis that the
1358 :			compiler itself uses.)
1359 :
1360 :			Also patched src/system/testml to have it activate those extra anchor
1361 :			bindings in config/extrapathconfig.

1366 :			Tag: blume-22051115-libraries
1367 :			Description:
1368 :
1369 :			This change affects the way the following libraries are tied into
1370 :			the system:
1371 :
1372 :			$/basis.cm
1373 :			$/smlnj-lib.cm
1374 :			$/pp-lib.cm
1375 :			$/controls-lib.cm
1376 :			$/html-lib.cm
1377 :			$/ml-yacc-lib.cm
1378 :
1379 :			These libraries are now internally (as seen from the source code
1380 :			of the implementation itself) known by the following names:
1381 :
1382 :			$smlnj/basis/basis.cm
1383 :			$smlnj/smlnj-lib/smlnj-lib.cm
1384 :			$smlnj/smlnj-lib/pp-lib.cm
1385 :			$smlnj/smlnj-lib/controls-lib.cm
1386 :			$smlnj/smlnj-lib/html-lib.cm
1387 :			$smlnj/ml-yacc/ml-yacc-lib.cm
1388 :
1389 :			This makes it possible to work with code that requires different
1390 :			versions of these libraries, and which refers to these libraries using
1391 :			their "default" names (i.e., the first set of names above). In other
1392 :			words, one can un-define or re-define those default names without
1393 :			compromising the proper functioning of the compiler itself.
1394 :
1395 :			A similar procedure had already been performed for several of the
1396 :			MLRISC libraries that are linked into the compiler. I did some
1397 :			cleanup on this code.
1398 :
1399 :			A new file in the config directory (named extrapathconfig) is
1400 :			responsible for setting up path anchors that the compiler itself does
1401 :			not need, but that are typically required by user code.

1581 :			Description:
1582 :
1583 :			Added mechanism for re-creating a heap file for the interactive system
1584 :			after configuration variables have been changed.
1585 :
1586 :			CM.redump_heap : string -> unit
1587 :
1588 :			This is much like SMLofNJ.exportML, but starting from the resulting
1589 :	blume	2155	heap does not return to the caller of CM.redump_heap but
1590 :	mblume	1792	restarts the interactive system from scratch. The original call of
1591 :			CM.redump_heap does not return but ends the interactive session.
1592 :			Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1593 :
1594 :			Internally, redump_heap winds the dynamic execution context back to
1595 :			the point where the original heap image was created and re-executes
1596 :			the heap image generation code in the boot code.

1717 :			It will probably also work on the Sparc (will test some time later).
1718 :
1719 :			- removed old "HACKED_STANDALONE" hack from runtime
1720 :
1721 :			To be able to test this, uncomment the request for "heap2asm" in
1722 :			config/targets prior to installation. (Notice that this is different
1723 :			from "heap2exec" mentioned below. Not a typo.)
1724 :
1725 :			To perform an actual test, run the command
1726 :
1727 :			$ bin/heap2exec heapfile execfile
1728 :
1729 :			(You can put heap2exec on your shell's path.)
1730 :

1732 :
1733 :			$ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1734 :
1735 :			This will create a standalone executable called "mly" which you can

1882 :			Description:
1883 :
1884 :			The compiler can now be compiled in a mode that makes structure Position
1885 :			equal to Int64. The default, however, is unchanged (Position = Int31)
1886 :			for the time being.
1887 :
1888 :			To enable 64-bit positions, use the following procedure:
1889 :
1890 :			1. Start sml
1891 :			2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1892 :			3. Type
1893 :			#set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1894 :			4. Run CMB.make() as usual.
1895 :
1896 :			This is barely tested. The only test so far was a little SML program
1897 :			counting the number of characters in an 8-gigabyte file by
1898 :			reading it character-by-character. That test was successful.
1899 :
1900 :			In support of 64-bit positions, a number of new functions have been
1901 :			added to the runtime system.

1980 :			Description:
1981 :
1982 :			Structure Word64 is now (almost) complete, word literals and patterns
1983 :			seem to work. There are a few odd pieces missing. In particular,
1984 :			I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1985 :			at the moment.
1986 :
1987 :			Making Word64 official would mean that LargeWord becomes Word64. But
1988 :			this requires extreme care because most word-word conversions have to
1989 :			go through LargeWord, so making a mistake means loss of efficiency or
1990 :			worse. Eventually there will be a solution similar to (but actually
1991 :			simpler than) what I did with IntInf.

2071 :			Tag: blume-20041020-standalone-backtrace
2072 :			Description:
2073 :
2074 :			Added a mechanism for getting back-trace information from standalone
2075 :			programs. Here is how it works:
2076 :
2077 :			1. The part of the program from which you want to get backtrace
2078 :			information (usually the whole program) should be wrapped with
2079 :			BackTrace.monitor. This is a (unit->'a)->'a function, and your
2080 :			main program could be modified from something like
2081 :
2082 :			fun main (pgm, args) = ...
2083 :
2084 :			to
2085 :
2086 :			fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2087 :
2088 :			2. To be able to access BackTrace.monitor, you have to add
2089 :			library $smlnj-tdp/plugins.cm to the .cm file that contains your
2090 :			main function.
2091 :
2092 :			3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2093 :			CM might have created in the past for your project).
2094 :
2095 :			4. Build the system using this command line:
2096 :
2097 :			ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2098 :			myprog.cm MyProg.main myprog
2099 :
2100 :			instead of the usual
2101 :
2102 :			ml-build myprog.cm MyProg.main myprog
2103 :
2104 :			I changed a library name:
2105 :
2106 :			$/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2107 :
2108 :			New libraries:
2109 :
2110 :			$smlnj-tdp/back-trace.cm
2111 :			-- when loaded causes the back-trace plugin to be installed
2112 :			$smlnj-tdp/coverage.cm
2113 :			-- when loaded causes the coverage plugin to be installed

2129 :			Description:
2130 :
2131 :			* Test coverage tool added!
2132 :			* Further reorganization of tracing-, debugging-, and profiling support:
2133 :
2134 :			- moved original BTImp -- now called BackTrace -- into a separate
2135 :			library called $/trace-debug-profile.cm
2136 :			- eliminated all mentions of BTrace from SMLofNJ.Internals
2137 :			- only the instrumentation mechanism is now left in the compiler proper
2138 :			- BackTrace module is a plugin which is NOT plugged in by default
2139 :			- Coverage module is another such plugin
2140 :
2141 :			To get the benefits of any of these plugin modules, the code in
2142 :			question must be compiled with tdp instrumentation turned on. This
2143 :			can be done by setting SMLofNJ.Internals.TDP.mode to true.
2144 :			(The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2145 :
2146 :			Plugins are selected at link time. (Pre-compiled instrumented code
2147 :			can be re-loaded with different plugins in effect.) When an
2148 :			instrumented module is linked, whatever plugins are at that time
2149 :			enabled will come into effect for that module.
2150 :
2151 :			To enable the back-trace plugin, load library $/trace-debug-profile.cm
2152 :			and invoke BackTrace.install() (e.g., from the interactive prompt).
2153 :			To enable the coverage plugin, load the same library and invoke
2154 :			Coverage.install().
2155 :
2156 :			Back-traces are generated automatically on uncaught exceptions and
2157 :			when the code in question explicitly invokes BackTrace.trigger().
2158 :
2159 :			Coverage (and execution frequency-) information must be queried
2160 :			explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2200 :
2201 :			Made some minor modifications to elabcore.sml to have source regions

2209 :			Description:
2210 :
2211 :			Fixed handling of keywords in .cm files: After seeing "is" the lexer
2212 :			treats subsequent occurrences of "group", "library", "source", "is",
2213 :			"*", and "-" as ordinary identifiers rather than keywords.
2214 :
2215 :			Most seriously, this fixes a problem with CM's "shell" tool. The tool
2216 :			is supposed to accept a tool argument called "source", but this did
2217 :			not work because of the clash with the keyword.

2261 :
2262 :			* Moved the "version" magic into its own little library under

2277 :			Tag: blume-20040929-autoversion
2278 :			Description:
2279 :
2280 :			Implemented some CM magic to have
2281 :			file src/compiler/TopLevel/main/version.sml
2282 :			generated automagically.
2283 :			The version is taken from two files: config/version and config/release.
2284 :			The first is expected to contain a two-part version number such as 110.49.
2285 :			The second should contain a single number, but it may be missing.
2286 :
2287 :			If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2288 :			time the version tool is loaded (which is the first time you say CMB.make),
2289 :			then the tool will increment the value stored in config/release every
2290 :			time CMB.make is invoked.
2291 :
2292 :			The binfile format is now insensitive to anything beyond the first
2293 :			two components of a version number, so bumping the release does not render
2294 :			binfiles incompatible. Auto-bumping can be used to keep track of versions
2295 :			during development without invalidating existing binfiles.
2296 :
2297 :			In any case, every CMB.make updates the date information in version.sml.
2298 :			(This is the date that is printed in the banner.)

2311 :			Tag: blume-20040927-controls
2312 :			Description:
2313 :
2314 :			Added two pieces of functionality to the Controls interface:
2315 :
2316 :			1. val save'restore: 'a control -> unit -> unit
2317 :
2318 :			grabs the current value of the control in stage 1 and restores it
2319 :			in stage 2.
2320 :
2321 :			2. val set' : 'a control * 'a -> unit -> unit
2322 :
2323 :			stores the given value into the control in stage 2 (i.e., delayed)
2324 :			but does all error checking in stage 1.
2325 :			(This is for string controls that need to do parse their argument --
2326 :			something that might fail. In some cases, notably in CM, one
2327 :			already knows the intended argument but wants to delay the actual
2328 :			assignment until a time when error recovery would be more difficult.)
2329 :
2330 :			Changed the handling of controls in tool arguments to classes "sml" and
2331 :			"lazysml":
2332 :			- use Controls.save'restore as a more robust way of restoring the
2333 :			old value (in particular: without having to re-parse the string)
2334 :			- use controls to handle the "overload" keyword in the init group
2335 :			(I believe this change actually fixes a long-standing obscure bug.)

2340 :			Tag: blume-20040927-lazysml
2341 :			Description:
2342 :
2343 :			Added a new tool class called "lazysml" to CM's tool chest. The only
2344 :			difference to "sml" is that compilation is done with Control.lazysml
2345 :			set to true. A source of class "lazysml" is automatically recognized
2346 :			by a file name suffix of ".lml".
2347 :
2348 :			In addition to the above feature, the original class "sml" now also
2349 :			supports a tool argument "lazy" which has the same effect. As a
2350 :			result, the following three lines are equivalent:
2351 :
2352 :			foo.sml : lazysml
2353 :			foo.sml : sml (lazy)
2354 :			foo.sml (lazy)
2355 :
2356 :			The setting goes into effect both during parsing and during
2357 :			compilation. The original setting is restored right after parsing and
2358 :			after compilation, respectively.
2359 :
2360 :			In addition to all the above, there is also a general mechanism to set
2361 :			ANY of the "controls" that are available at the command line via
2362 :			"-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2363 :			apply as well. (In fact, "lazy" is implemented as a special case of
2364 :			the general mechanism.)
2365 :
2366 :			The .cm file syntax uses a new keyword tool argument called "with".
2367 :			There are several ways of indicating the desired settings:
2368 :
2369 :			foo.sml (with:parser.quotations=true)
2370 :			foo.sml (with:(name:parser.quotations value:true))
2371 :			foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2372 :			foo.sml (with:(name1=value1 name2=value2 ...))
2373 :			foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2374 :
2375 :			etc.
2376 :
2377 :			Another possible abbreviation is to leave out the =v or value:v part
2378 :			if the name refers to a boolean control (in which case the value is
2379 :			taken to be true). Thus, one could get lazy sml also by saying:
2380 :
2381 :			foo.sml (with:parser.lazy-keyword=true)
2382 :			foo.sml (with:parser.lazy-keyword)
2383 :			foo.sml (with:(name:parser.lazy-keyword value:true))
2384 :			foo.sml (with:(name:parser.lazy-keyword))

2614 :			- various minor bugfixes to ml-nlffigen
2615 :			- a beginning of a manual for nlffi
2616 :
2617 :			- eliminated 'export name=value' in config/install.sh as this does
2618 :			not work with certain versions of /bin/sh
2619 :			(Thanks to David King at Motorola for catching this.)
2620 :
2621 :			- several bugfixes provided or suggested by David Hansel at Reactive Systems:
2622 :			- added a test for tm==NULL to gmtime.c and localtime.c
2623 :			- applied patch for incorrect GetFileTime under win32
2624 :			- toSeconds -> toMilliseconds in Win32/win32-process.sml

2736 :			Description:
2737 :
2738 :			Changed the interface of structures Timer and Unix to match the most
2739 :			recent Basis spec.
2740 :
2741 :			In the case of Unix there still seems to be an open/weird issue:
2742 :
2743 :			The {text,bin}{In,Out}streamOf functions are supposed to create
2744 :			fresh streams whenever they are called -- as opposed to have them
2745 :			return the same stream every time. This design is supposed to
2746 :			prevent space leaks caused by proc values hanging on to streams.
2747 :
2748 :			The reap function, on the other hand, is supposed to close the
2749 :			streams. This cannot be done without having a handle on the
2750 :			stream in proc after all...
2751 :
2752 :			I took the liberty to implement the following stopgap solution:
2753 :
2754 :			The proc value hangs on to the most recently created stream(s).
2755 :			Reap closes those. If either or both of the two streams hadn't
2756 :			been created at all yet, then reap will close the corresponding
2757 :			file descriptors directly.
2758 :
2759 :			PS: I don't understand the original space leak argument anymore. If
2760 :			a proc hangs on to the imperative stream, then I/O operations on those
2761 :			will advance the state of the cached stream and avoid the space leak.

2775 :			Description:
2776 :
2777 :			CM now ignores (but still accepts) the "owner" information in group
2778 :			descriptions. The owner of a group is its next enclosing
2779 :			library. Each group must have a unique owner. (There is a virtual
2780 :	mblume	1505	"toplevel" library that owns groups which are not nested within a real
2781 :	mblume	1498	library.) Previously, each group had to explicitly declare its owner,
2782 :			and CM would check that such a declaration is correct. The new scheme
2783 :			is to have CM check that for each group there is precisely one owning
2784 :			library.
2785 :
2786 :			The advantage of the new scheme is that the programmer no longer needs
2787 :			to maintain the somewhat annoying owner information. The downside is
2788 :			that CM cannot enforce the ownership rule across multiple runs of
2789 :			CM.make. Fortunately, enclosing the same group in two different
2790 :			libraries A and B which are not part of the same program does not
2791 :			cause real problems.

2839 :

2841 :
2842 :	mblume	1490	Here is David's e-mail:
2843 :
2844 :			Hi,
2845 :
2846 :			Attached to this email you find a diff against sml/nj 110.45
2847 :			that will enable socket support under Windows.
2848 :
2849 :			To apply the patch (using unix or cygwin)
2850 :			1) gunzip runtime.diff.gz
2851 :			2) "cd" into "src/runtime" in the source tree of a fresh
2852 :			110.45 installation.
2853 :			3) patch -p 1 < [your/path/to]runtime.diff
2854 :
2855 :	blume	2155	The code compiles fine but has NOT yet been extensively tested.
2856 :			I only ran a few tests for basic socket client functionality
2857 :			(which worked fine). Especially the functions that use ioctl
2858 :	mblume	1490	are not tested at all and might not work (see below).
2859 :
2860 :			I implemented this since we want to move to a newer version of sml/nj
2861 :			but need socket support in order to use it. This is the first time I
2862 :			even had a look at the sml/nj source, so please review my changes
2863 :			before making this part of the distribution! Here are a few issues
2864 :	blume	2155	that I think might be better for someone to solve who is more
2865 :	mblume	1490	familiar with the sml/nj source (and socket programming):
2866 :
2867 :			- getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
2868 :			exception since I could not figure out what the windows equivalent
2869 :			of these functions is
2870 :
2871 :			- In sockets-osdep.h there are a some #include statements that are
2872 :			only used in a few files that include sockets-osdep.h
2873 :
2874 :			- In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
2875 :			does not process its return value since I don't know how to
2876 :			report an error upwards.
2877 :
2878 :			- It would probably be good to have a call to WSACleanup() when
2879 :	blume	2155	the library is unloaded (if there is such a possibility).
2880 :	mblume	1490	Otherwise I think Windows will take care of this automatically
2881 :			when the process finishes.
2882 :
2883 :			- I used ioctlsocket() as a replacement for ioctl() but I have
2884 :			no idea if that is actually the proper replacement on Windows.
2885 :
2886 :			- All these issues are marked in the code by "FIXME" comments.
2887 :
2888 :	blume	2155	We use sml/nj extensively in our products and are quite happy
2889 :			with it. I hope this contribution will help you.

3059 :			(The mechanism was broken and could not be fixed easily. Moreover,

3061 :			lib during installation. I originally implemented this directive as a

3063 :			Now that things have been stable for a long time and going back to the
3064 :			old CM is not an option, there is no reason to keep it around.)

3113 :			Tag: blume-20030926-ppautoload
3114 :			Description:
3115 :
3116 :			I modified the read-eval-print loop so that the autoloader gets
3117 :			invoked whenever the prettyprinter tries to look up a symbol that
3118 :			is not currently defined in the toplevel environment but which
3119 :			appears in CM's autoload registry. As a result, we see far fewer of
3120 :			those ?.Foo.Bar.xxx names in the prettyprinter's output.
3121 :
3122 :			In addition to this I tried to clean up some pieces of the Basis
3123 :			implementation (e.g., Socket, Word8Array) in order to prevent other
3124 :			instances of these ?.Foo.Bar.xxx names from being printed.
3125 :
3126 :			The mechanism that picks names for types still needs some work, though.
3127 :			(Right now it seems that if there is a type A.t which is defined to
3128 :	mblume	1394	be B.u, but B is unavailable at toplevel, then A.t gets printed as
3129 :			"?.B.u" although the perhaps more sensible solution would be to use
3130 :	mblume	1393	"A.t" in this case. In other words, the prettyprinter should follow
3131 :			a chain of DEFtycs not farther than there are corresponding toplevel
3132 :			names in the current environment.)

3138 :			Description:
3139 :
3140 :			Another installer tweak: All the ML code for the installer is now
3141 :			compiled during CMB.make and put into a little library called
3142 :			$smlnj/installer.cm. The installation then simply invokes
3143 :
3144 :			sml -m $smlnj/installer.cm
3145 :
3146 :			and everything happens automagically.
3147 :
3148 :			Win32: ML code senses value of environment variable SMLNJ_HOME.
3149 :			Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3150 :			and BINDIR.
3151 :
3152 :			The new scheme guarantees that the ML code responsible for the installation
3153 :			is in sync with the APIs of the main system. Also, the installer is
3154 :			somewhat faster because the installer script is precompiled.

3161 :
3162 :			Added a signature SYNCHRONOUS_SOCKET to basis.cm. This is like SOCKET
3163 :			but excludes all non-blocking operations. Defined SOCKET (in Basis)
3164 :			and CML_SOCKET in terms of SYNCHRONOUS_SOCKET. Removed superfluous
3165 :			implementations of non-blocking operations from CML's Socket
3166 :			structure.

3171 :			Tag: blume-20030924-sockets
3172 :			Description:
3173 :
3174 :			1. Fixed SOCKET API and implementation to match Basis spec.
3175 :			This required changing the internal representation of sockets to one
3176 :			that remembers (for each socket file descriptor) whether it is currently
3177 :			blocking or non-blocking. This state is maintained lazily (i.e., a system
3178 :			call is made only if the state actually needs to change).
3179 :
3180 :			2. OS-specific details of sockets were moved into separate files, thus
3181 :			making it possible to unify the bulk of the socket implementations
3182 :			between Unix and Win32.
3183 :
3184 :			3. CML's socket API changed accordingly.
3185 :			(Note that we need to remove non-blocking functions from this API
3186 :			since they are redundant in the case of CML!)
3187 :
3188 :			4. CML's socket implementation now makes use of non-blocking functions
3189 :			provided by Basis, thus removing all OS-dependent code from this part
3190 :			of CML.
3191 :
3192 :			5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3305 :			Description:
3306 :
3307 :			Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3308 :			Modified config/install.bat to take advantage of it. Also modified

3317 :
3318 :			- made CML compile again under Win32
3319 :			- made eXene compile under Win32 (by providing a fake structure UnixSock
3320 :			and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3321 :			- fixed a bug in nowhere: it assumed that type OS.Process.status is the
3322 :			same as type int; under Win32 it isn't
3323 :			- fixed some slice-related problems in the win32-specific parts of CML
3324 :			- added a functor argument "sameVol" to os-path-fn.sml in the Basis
3325 :			(under Win32, the volume name is case-insensitive, and the
3326 :			OS.Path code compares volume names for equality)

3343 :	mblume	1350	Description:
3344 :
3345 :			1. Changed interface to vectors and arrays in Basis to match
3346 :			(draft) Basis spec.
3347 :			2. Added signatures and implementations of slices according to
3348 :			Basis spec.
3349 :			3. Edited source code throughout the system to make it compile again
3350 :			under 1. and 2. (In some cases code had to be added to have it
3351 :			match the new signatures.)
3352 :			4. MLRISC should be backward-compatible: the copies of the originals
3353 :			of files that needed to change under 3. were retained, the .cm files
3354 :			check the compiler version number and use old versions when
3355 :			appropriate.
3356 :			5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3357 :			dirstream -> string option (in accordance with Basis spec).
3358 :			6. When generating code that counts lines, ml-lex used function
3359 :			CharVector.foldli, taking advantage of its old interface.
3360 :			This has been replaced with the corresponding code from
3361 :			CharVectorSlice. (html-lex must be re-lexed!)
3362 :			7. BitArray in smlnj-lib/Util has been extended/modified to match the
3363 :			new MONO_ARRAY signature. (Do we need BitArraySlice?)
3364 :			8. Removed temporary additions (fromInternal, toInternal) from the
3365 :			(now obsolete) IntInf in smlnj-lib/Util.
3366 :			9. Cleaned up structure Byte.
3367 :			10. Added localOffset, scan, and fromString to Date (according to spec).
3368 :			Cleaned/corrected implementation of Date.
3369 :			(Still need to check for correctness; implement better canonicalizeDate.)
3370 :			11. Added "scan" to signature IEEE_REAL.
3371 :			12. Some improvements to IntInf [in particular: efficiency-hack for
3372 :			mod and rem when second operand is 2 (for parity checks).]
3373 :			13. Changed representation of type Time.time, using a single IntInf.int
3374 :			value counting microseconds. This considerably simplified the
3375 :			implementation of structure Time. We now support negative time
3376 :			values; scan and fromString handle signs.
3377 :			14. Functor PrimIO now takes two additional arguments (VectorSlice and
3378 :			ArraySlice).

3384 :			Description:
3385 :
3386 :			This is a major update which comes with a version number bump
3387 :			(110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3388 :			and an implementation of IntInf in the Basis.
3389 :
3390 :			There are a fairly large number of related changes and updates throughout
3391 :			the system:
3392 :
3393 :			Basis:
3394 :			- Implemented IntInf.
3395 :			- Made LargeInt a projection of IntInf (by filtering through INTEGER).
3396 :	mblume	1348	- Added some missing Real64 operations, most notably Real.toLargeInt.
3397 :	mblume	1347	- Added FixedInt as a synonym for Int32.
3398 :
3399 :			compiler:
3400 :			* Added support for a built-in intinf type.
3401 :			- literals
3402 :			- pattern matching
3403 :			- conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3404 :			- overloading on literals and operations
3405 :
3406 :			This required adding a primitive type intinf, some additional
3407 :			primops, and implementations for several non-trivial intinf
3408 :			operations in Core. (The intinf type is completely abstract
3409 :			to the compiler; all operations get delegated back to the Core.)
3410 :
3411 :			* Intinf equality is handled by polyequal. However, the compiler
3412 :			does not print its usual warning in this case (since polyequal
3413 :			is the right thing to do there).
3414 :
3415 :			* Improved the organization of structure InlineT.
3416 :
3417 :			* A word about conversion primops:
3418 :			If conversions involving intinf do not cancel out during
3419 :	mblume	1348	CPS contract, then the compiler must insert calls to Core functions.

3470 :			Tag: blume-20030811-windows
3471 :			Description:
3472 :
3473 :			Version number bumped to 110.42.9. NEW BOOTFILES!!!
3474 :
3475 :			http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3476 :
3477 :			This patch restores SML/NJ's ability to run under win32. There are a
3478 :			number of changes, including fixes for several bugs that had gone
3479 :			unnoticed until now:
3480 :
3481 :			- uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3482 :			trying to run the win32 version from within cygwin.)
3483 :
3484 :			- There are a number of simple .bat scripts that substitute for their
3485 :			corresponding Unix shell-scripts. (See below.)
3486 :
3487 :			- The internals of ml-build have been modified slightly. The main
3488 :			difference is that instead of calling ".link-sml" (or link-sml.bat)
3489 :			using OS.Process.system, the ML process delegates this task back
3490 :			to the script. Otherwise problems arise in mixed environments such
3491 :			as Cygwin where scripts look and work like Unix scripts, but
3492 :			where OS.Process.system cannot run them.
3493 :
3494 :			- In CM, the srcpath pickler used native pathname syntax -- which
3495 :			is incorrect in the case of cross-compilation. The new pickle format
3496 :			is independent of platform-specific naming conventions.
3497 :
3498 :			- Path configuration files (such as lib/pathconfig) can now choose
3499 :			between native and standard syntax. Placing a line of the form
3500 :
3501 :			standard!
3502 :
3503 :			into the file causes all subsequent paths to be interpreted using
3504 :			CM standard pathname syntax (= Unix conventions); a line
3505 :
3506 :			native!
3507 :
3508 :			switches back to native style. This was needed so that
3509 :			path config files can be written portably, see src/system/pathconfig.
3510 :
3511 :			- Runtime system:
3512 :
3513 :			- win32-filesys.c: get_file_time and set_file_time now
3514 :			access modification time, not creation time.
3515 :
3516 :			- I/O code made aware of new array representation.
3517 :
3518 :			- Bug fixes in X86.prim.masm.
3519 :
3520 :			- src/system/makeml made aware of win32. (For use under cygwin
3521 :			and other Unix-environments for windows.)
3522 :
3523 :			- In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3524 :			which caused BinIO.inputAll to fail consistently.
3525 :
3526 :			.bat scripts:
3527 :
3528 :			Windows .bat scripts assume that SMLNJ_HOME is defined.
3529 :
3530 :			- sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3531 :			applications (sml, ml-yacc, ml-lex).
3532 :			- ml-build.bat: analogous to ml-build.
3533 :			- config\install.bat: Analogous to config/install.sh. This requires
3534 :			that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3535 :			(nmake etc. must be on the path, and vcvars32 must have been run.)
3536 :			Moreover, sources for ml-lex and ml-yacc need to exist under src,
3537 :			and the bootfile hierarchy must have been unpacked under
3538 :			sml.boot.x86-win32.
3539 :			The script is very primitive and does a poor job at error checking.
3540 :			It only installs the base system, ml-lex, and ml-yacc. No other
3541 :			libraries are being installed (i.e., you get only those that
3542 :			are part of the compiler.)
3543 :			- link-sml.bat: analogous to .link-sml, but not currently used
3544 :
3545 :			Unrelated bug fixes:
3546 :
3547 :			- ml-nlffigen now exports structures ST_* corresponding to incomplete
3548 :			types.
3549 :			- Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3550 :			otherwise.)

3590 :
3591 :			This mainly affects the quality of error messages. However, some
3592 :			of the code is now more straightforward than before. (Treatment of
3593 :			the above four constructs in translate.sml is much simpler than
3594 :			the "macro-expansion" that was going on before. Plus, the mach-
3595 :			compiler no longer gets invoked just to be able to compile an

3886 :
3887 :			2. Added FormatComb and FORMAT_COMB to the CML version of the
3888 :			SML/NJ library (so that CML compiles again).
3889 :
3890 :			3. Modified init scripts because XXX_DEFAULT environment variables

3892 :			using the same environment variables that are also used for
3893 :			startup-time initialization of controls.)

3899 :			Description:
3900 :
3901 :			All pseudo-ops emitted before the first segment declaration
3902 :			such as TEXT, DATA, and BSS directives are assumed to be global
3903 :			declarations and are emitted first in the assembly file. This is
3904 :			useful in a number of situations where one has pseudo-ops that are not
3905 :			specific to any segment, and also works around the constraint that one
3906 :			cannot have client pseudo-ops in the TEXT segment.
3907 :
3908 :			Because no segment is associated with these declarations it is
3909 :			an error to allocate any space or objects before the first segment
3910 :			directive and an exception will be raised. However, we cannot make
3911 :			this check for client pseudo-ops.
3912 :
3913 :			These top level declarations are a field in the CFG graph_info.
3914 :			In theory you can continue to add to this field after the CFG has been
3915 :			built -- provided you know what you are doing;-)

3938 :			Description:
3939 :
3940 :			Applied the following bugfix provided by Emden Gansner:
3941 :
3942 :			Output is corrupted when outputSubstr is used rather than output.
3943 :
3944 :	blume	2155	The problem occurs when a substring
3945 :	blume	1189
3946 :			ss = (s, dataStart, dataLen)
3947 :
3948 :	blume	2155	where dataStart > 0, fills a stream buffer with avail bytes left.
3949 :			avail bytes of s, starting at index dataStart, are copied into the
3950 :	blume	1189	buffer, the buffer is flushed, and then the remaining dataLen-avail
3951 :	blume	2155	bytes of ss are copied into the beginning of the buffer. Instead of
3952 :			starting this copy at index dataStart+avail in s, the current code
3953 :	blume	1189	starts the copy at index avail.
3954 :
3955 :			Fix:
3956 :			In text-io-fn.sml, change line 695 from
3957 :			val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3958 :	blume	2155	to

3975 :			Description:
3976 :
3977 :			Added full support for div/mod/rem/quot on the x86, using the machine
3978 :			instruction's two results (without clumsily recomputing the remainder)
3979 :			directly where appropriate.
3980 :
3981 :			Some more extensive power-of-two support was added to the x86 instruction
3982 :			selector (avoiding expensive divs, mods, and muls where they can be
3983 :			replaced with cheaper shifts and masks). However, this sort of thing
3984 :			ought to be done earlier, e.g., within the CPS optimizer so that
3985 :			all architectures benefit from it.
3986 :
3987 :			The compiler compiles to a fixed point, but changes might be somewhat
3988 :			fragile nevertheless. Please, report any strange things that you might
3989 :			see wrt. div/mod/quot/rem...

4018 :
4019 :
4020 :			CHANGES:
4021 :
4022 :			* removed REMT from mltree (remainder should never overflow).
4023 :
4024 :			* added primops to deal with divisions of all flavors to the frontend
4025 :
4026 :			* handled these primops all the way through so they map to their respective
4027 :			MLRISC support
4028 :
4029 :			* used these primops in the implementation of Int, Int32, Word, Word32
4030 :
4031 :			* removed INLDIV, INLMOD, and INLREM as they are no longer necessary
4032 :
4033 :			* parameterized INLMIN, INLMAX, and INLABS by a numkind
4034 :
4035 :			* translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
4036 :			floating point
4037 :
4038 :			* used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
4039 :			and Real (but Real.abs maps to a separate floating-point-only primop)
4040 :
4041 :
4042 :			TODO items:
4043 :
4044 :			* Hacked Alpha32 instruction selection, disabling the selection of REMx
4045 :			instructions because the machine instruction encoder cannot handle
4046 :			them. (Hppa, PPC, and Sparc instruction selection did not handle
4047 :			REM in the first place, and REM is supported by the x86 machine coder.)
4048 :
4049 :			* Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
4050 :			selection phase. (The two can be streamlined because the hardware
4051 :			delivers both quotient and remainder at the same time anyway.)
4052 :
4053 :			* Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
4054 :			(Currently the behavior is inconsistent both across architectures and
4055 :			wrt. the draft Basis spec.)
4056 :
4057 :			* Word8 should eventually be handled natively, too.
4058 :
4059 :			* There seems to be one serious bug in mltree-gen.sml. It appears, though,
4060 :			as if there currently is no execution path that could trigger it in
4061 :			SML/NJ. (The assumptions underlying functions arith and promotable do not
4062 :			hold for things like multiplication and division.)

4067 :			Tag: blume-20020327-mlrisc-divisions
4068 :			Description:
4069 :
4070 :			Added support for all four division operations (ML's div, mod, quot,
4071 :			and rem) to MLRISC. In the course of doing so, I also rationalized
4072 :			the naming (no more annoying switch-around of DIV and QUOT), by
4073 :			parameterizing the operation by div_rounding_mode (which can be either
4074 :			DIV_TO_ZERO or DIV_TO_NEGINF).
4075 :
4076 :			The generic MLTreeGen functor takes care of compiling all four
4077 :			operations down to only round-to-zero div.
4078 :
4079 :			Missing pieces:
4080 :
4081 :			* Doing something smarter than relying on MLTreeGen on architectures
4082 :			like, e.g., the x86 where hardware division delivers both quotient and
4083 :			remainder at the same time. With this, the implementation of the
4084 :			round-to-neginf operations could be further streamlined.
4085 :
4086 :			* Remove inlining support for div/mod/rem from the frontend and replace it
4087 :			with primops that get carried through to the backend. Do this for all
4088 :			int and word types.

4093 :			Tag: blume-20020325-divmod
4094 :			Description:
4095 :
4096 :			I improved (hopefully without breaking them) the implementation of Int.div,
4097 :			Int.mod, and Int.rem. For this, the code in translate.sml now takes
4098 :			advantage of the following observations:
4099 :
4100 :			Let q = x quot y r = x rem y
4101 :			d = x div y m = x mod y
4102 :
4103 :			where "quot" is the round-to-zero version of integer division that
4104 :			hardware usually provides. Then we have:
4105 :
4106 :			r = x - q * y where neither the * nor the - will overflow
4107 :			d = if q >= 0 orelse x = q * y then q else q - 1
4108 :			where neither the * nor the - will overflow
4109 :			m = if q >= 0 orelse r = 0 then r else r + y
4110 :			where the + will not overflow
4111 :
4112 :			This results in substantial simplification of the generated code.
4113 :			The following table shows the number of CFG nodes and edges generated
4114 :			for
4115 :			fun f (x, y) = x OPER y
4116 :			(* with OPER \in div, mod, quot, rem *)
