44 :     Description:
45 :    
46 :     1) Change of SourceMap interface.
47 :     related to fix of off-by-one error in lexer (committed earlier?), and cleanup of noweb code
48 :     added by Norman Ramsey many years ago (but little used today).
49 :    
50 :     3) Slight cleanup of match compiler, eliminatiing compiler/FLINT/tempexpn.sml file that
51 :     was part of unused implementation of pattern templates (pattern macros).
52 :    
53 :     4) Modification of type checker to add "culprit tracking" for improved type error messages
54 :     (printing of additional culprit information is controlled by ElabControl.showTypeErrorCulprits
55 :     flag, default false, added in revision 3652). The culprit tracking needs to be debugged
56 :     and improved, and the presentation of the culprits needs to be done better.

718 :     Description:

721 :     Additional bug fixes included:
722 :    
723 :     * Timer.cpu_timer, etc. type printing corrected (by making

731 :     Description:
732 :    
733 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
734 :    
735 :     Also, changed the handling of "no core access": When translate.sml
736 :     needs access to a core exception at a time when the core has not
737 :     been set up yet (this only happens when compiling system/smlnj/init/*),
738 :     then don't bother generating the corresponding tests.
739 :    
740 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
741 :     the exception. Unfortunately, that confuses the plambda type checker.
742 :     Moreover, it does not do any good, because at runtime we don't expect
743 :     such an exception to be ever raised. (The code in system/smlnj/init/*
744 :     has to be written very carefully with this in mind!)

756 :     Description:
757 :    
758 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
759 :     with an explicit test for zero division. This should fixes several
760 :     regressions and makes it possible for downstream optimization phases
761 :     to treat these operations as "pure" when they are applied to unsigned

777 :    
778 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes

783 : blume 2610 Name: Matthias Blume (http://www.tti-c.org/blume/)
784 :     Date: 2007/05/23 22:30:00 CDT
785 :     Description:
786 :    
787 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
788 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
789 :    
790 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
791 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
792 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
793 :     while running CMB.make. The point is that the single symbol
794 :     NO_PLUGINS is definde in all three cases.)
795 :    
796 :     I changed the three locations within the sources that get compiled
797 :     during CMB.make where ml-yacc or ml-lex input is processed: When
798 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
799 :     is bypassed.
800 :    
801 :     When bootstrapping new versions of the compiler, there can be
802 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
803 :     are not available or otherwise not operational. In this case one can
804 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
805 :     do so, the following command should be issued at the interactive
806 :     prompt:
807 :    
808 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
809 :    
810 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
811 :     files that normally would be generated by ml-yacc and ml-lex.
812 :     (Copies of these files are in the repository.)

827 : blume 2589 Date: 2007/05/23 09:50:00 CDT
828 :     Description:
829 :    
830 :     Changed the installation mechanism for CM tool plugins. These are
831 :     just libaries and now get installed like ordinary libaries.
832 :    
833 :     There are now a number of new installation targets that give some
834 :     fine-grain control over what classes and suffixes are known, and what
835 :     they will map to.
836 :     See config/targets for details.
837 :    
838 :     The code that caused plugin installation as part of running a
839 :     tool's "build" script has been removed. (The build script is for
840 :     building, not for installing.)

844 : blume 2578 Date: 2007/05/22 11:50:00 CDT
845 :     Description:
846 :    
847 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
848 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
849 :     CM fail if a shell tool reports a non-success exit status. If
850 :     the control is set to true, then CM will press on after tool failures
851 :     in the event that the target files exist (even though they are
852 :     considered outdated). Turning the control to true can be useful for
853 :     bootstrapping.

858 :     Description:
859 :    
860 :     Merge of ml-lpt revisions for 110.64.
861 :    
862 :     The name of several ml-lpt-lib modules has changed:
863 :     Repair => AntlrRepair
864 :     StreamPos => AntlrStreamPos
865 :     ErrHandlerFn => AntlrErrHandler
866 :     EBNF => AntlrEBNF
867 :    
868 :     The ml-antlr specification format has changed: declarations such as
869 :     %tokens and nonterminal definitions can occur *multiple* times in the
870 :     same specification. The semantics are such that each new declaration
871 :     extends the previous ones. This does not apply to %start or %name,
872 :     of course.
873 :    
874 :     Importing a grammar via %import now includes *all* declarations in from
875 :     the imported grammar, except for %name, %entry, and %start. Tokens
876 :     and nonterminals can be dropped using the new %dropping clause of the
877 :     %import directive; the separate %drop and %extend have been removed.
878 :    
879 :     We now allow optional type annotations on nonterminals, using the %nonterms
880 :     directive as in ml-yacc.
881 :    
882 :     The refcell construct is now implemented using SML's regular reference
883 :     cells, so the :== and !! notation has been deprecated.
884 :    
885 :     The ml-antlr tool now does much more checking of specifications, and
886 :     its error messages have been greatly improved. Error repair for
887 :     generated parsers has been completely rewritten, and is now both
888 :     much faster and more accurate.
889 :    
890 :     ml-ulex is now more lenient with escape codes (non-SML-standard
891 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
892 :     Also, character classes may now include a "-" character at the beginning
893 :     as is standard in most other regexp tools.
894 :    
895 :     All of these changes are documented in the user guide, which has
896 :     been updated and improved with this merge.

901 :     Revision: r2492
902 :     Description:
903 :    
904 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
905 :     Significant changes in FLINT and the front end, mostly having to do
906 :     with a reorganized system for handling primops. Various bug fixes
907 :     and improvements in printing signatures.

911 :     Date: 2007/05/02
912 :     Description:
913 :    
914 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
915 :     The ml-antlr specification format has changed: declarations such as
916 :     %tokens and nonterminal definitions can occur *multiple* times in the
917 :     same specification. The semantics are such that each new declaration
918 :     extends the previous ones. Grammar extension constructs have also
919 :     changed. We now allow type annotations on nonterminals. Finally,
920 :     the refcell construct is now implemented using SML's regular reference
921 :     cells, so the :== and !! notation has been deprecated. All of these
922 :     changes will appear in the 110.64 user guide for ml-lpt.
923 :    
924 :     The ml-antlr tool now does much more checking of specifications, and
925 :     its error messages have been greatly improved. There has also been
926 :     some work on the error repair process for generated parsers, but this
927 :     will be further improved in 110.64.

932 :     Description:
933 :    
934 :     More Basis fixes: The Char.fromString (etc.) functions did not handle
935 :     the "\uxxxx" escape sequence. There is still an outstanding bug with
936 :     String.fromString the tail is a format escape. I added a comment to
937 :     this effect in Basis/Implementation/string.sml.

1016 :     Description:
1017 :    
1018 :     Added preliminary support in MLRISC for Staged Allocation, a technique
1019 :     for specifying calling conventions (see
1020 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
1021 :     Initially, we plan to use this code to generate C calls for the AMD64.
1022 :    
1023 :     The staged allocation code base resides in MLRISC/staged-allocation,
1024 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

1030 :    
1031 :     Bug fix: when SaveCState was called with two values to save, a subsequent

1044 :    
1045 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
1046 :     of the range -128 ... 127. I've changed the code so that the range
1047 :     check is disabled. Only the low order 8 bits of the immediate operand

1089 :     Description:
1090 :    
1091 :     Brought ml-lpt manual up-to-date with the code. Many minor
1092 :     improvements to the tools, and a few minor bugfixes. Prepared
1093 :     ml-lpt-lib for integration with new UTF8 structure. Changed
1094 :     the interface for creating streams in ml-ulex (we now support
1095 :     stream creation from several kinds of sources). Overall, the
1096 :     tools are now quite stable, and their interfaces are unlikely to
1097 :     change in a way that would break compatibility. More work,
1098 :     however, is needed in the documentation.

1103 :     Description:
1104 :    
1105 :     Implemented library installer. Moved CM plugin code for
1106 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
1107 :     their respective trees. Implemented CM plugin for ml-ulex
1108 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
1109 :     and ml-antlr.
1110 :    
1111 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
1112 :     CM tools. (It turns out to be too messy to do otherwise because
1113 :     there is too much code that during installation relies on the presence
1114 :     of these tools -- resulting in a tricky ordering problem.)

1119 :     Description:
1120 :    
1121 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
1122 :     Modified CM's startup code to use shiftArgs as it processes
1123 :     command line arguments. This way, the init code in each .sml-file
1124 :     or library that is mentioned at the top level will see only
1125 :     those arguments that have not yet been processed at this point.
1126 :     In other words, the init code can "seize control" and process the
1127 :     remaining command line.

1141 :    
1142 :     Added the UTF8 structure and signature from the Moby compiler to

1194 :     Description:
1195 :    
1196 :     Added code to CM's "standard shell tool" implementation which
1197 :     causes it to tolerate (with a warning) the situation where the shell
1198 :     command fails (e.g., due to the shell command's non-existence)
1199 :     as long as all target files exist.
1200 :    
1201 :     This makes it possible to, e.g., build ml-yacc from sources even if
1202 :     svn checkout messed up the time stamps on files in such a way that
1203 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
1204 :     be needed to re-process yacc.grm, but obviously it might not yet be
1205 :     available at that time.)

1211 :    
1212 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
1213 :     recvVecFromNB' in the SOCKET signature. This error is actually
1214 :     in the SML Basis specification too.

1246 :    
1247 :     New working release (110.60). NEW BOOTFILES!
1248 :    
1249 :     This is the first subversion-hosted release. There are also changes
1250 :     to the directory layout. Here is a table:
1251 :    
1252 :     (All pathnames are relative to the SML/NJ "root" directory.)
1253 :    
1254 :     config -> config
1255 :    
1256 :     src/cm -> base/cm
1257 :     src/compiler -> base/compiler
1258 :     src/runtime -> base/runtime
1259 :     src/system -> base/system

1262 :    
1263 :     src/READMES -> base/READMES
1264 :     src/$notefile -> base/NOTES/$notefile
1265 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1266 :     MACOSXINSTALL WININSTALL
1267 :    
1268 :     src/smlnj-lib -> smlnj-lib
1269 :     src/MLRISC -> MLRISC
1270 :     ckit -> ckit
1271 :     src/cml -> cml
1272 :     src/eXene -> eXene
1273 :     src/heap2asm -> heap2asm
1274 :     src/lexgen -> lexgen
1275 :     src/ml-burg -> ml-burg
1276 :     src/ml-lex -> ml-lex
1277 :     src/ml-yacc -> ml-yacc
1278 :     src/ml-nlffi-lib -> nlffi/lib
1279 :     src/ml-nlffigen -> nlffi/gen
1280 :     src/smlnj-c -> smlnj-c
1281 :     src/tools/TraceDebugProf -> trace-debug-profile
1282 :    
1283 :     In addition, there is also a new
1284 :    
1285 :     ml-lpt
1286 :    
1287 :     directory containing two new program generator tools: ml-ulex and
1288 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1289 :     LL(k) parser generator). These tools are currently "beta-quality"
1290 :    
1291 :     The latest versios of the sources can now be obtained anonymously
1292 :     via subversion. For this, it is useful to first check out
1293 :    
1294 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1295 :    
1296 :     and put the resulting directory on your shell's PATH. This provides
1297 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
1298 :     and refresh-all.sh.
1299 :    
1300 :     To create a freshly checked-out copy of the sources, do
1301 :    
1302 :     checkout-all.sh [dir]
1303 :    
1304 :     where dir is the optional SML/NJ root directory (default is ".").
1305 :    
1306 :     This creates the above directory layout. Each subdirectory of
1307 :     the root is under individual subversion control. The stat-all.sh
1308 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
1309 :     each of these subtrees.

1314 :     Description:
1315 :    
1316 :     Reorganized directory layout.
1317 :    
1318 :     This is a temporary solution, more reorganization is to come.
1319 :    
1320 :     The basic idea is to have a number of toplevel trees, each corresponding
1321 :     to a well-defined part of the overall system. Each part can be
1322 :     maintained individually, even in separate source repositories,
1323 :     although currently we still serve everything out of the main
1324 :     smlnj-gforge tree.
1325 :    
1326 :     Installer and and scripts have been updated to reflect the new
1327 :     layout. The installer (base/src/system/smlnj/installer) is now
1328 :     "scriptable" to avoid burning too much knowledge about the
1329 :     layout into SML source code. The main script used by the installer
1330 :     is in config/actions.
1331 :    
1332 :     The main change is that many of the subdirectories of what used to
1333 :     be known as "src" have moved to the toplevel. The "src" directory
1334 :     itself has moved down into a subtree called "base". (We may eventually
1335 :     get rid of the extra level of indirection represented by "src".)
1336 :    
1337 :     The layout is now as follows:
1338 :    
1339 :     toplevel tree name | default repository
1340 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1341 :     -------------------+----------------------------------------------------
1342 :     config | $gf/config/trunk
1343 :     |
1344 :     base | $gf/sml/trunk
1345 :     |
1346 :     smlnj-lib | $gf/smlnj-lib/trunk
1347 :     MLRISC | $gf/MLRISC/trunk
1348 :     |
1349 :     ml-yacc | $gf/ml-yacc/trunk
1350 :     ml-lex | $gf/ml-lex/trunk
1351 :     ml-burg | $gf/ml-burg/trunk
1352 :     lexgen | $gf/lexgen/trunk
1353 :     heap2asm | $gf/heap2asm/trunk
1354 :     |
1355 :     cml | $gf/cml/trunk
1356 :     eXene | $gf/eXene/trunk
1357 :     ckit | $gf/ckit/trunk
1358 :     nlffi | $gf/nlffi/trunk
1359 :     |
1360 :     smlnj-c | $gf/smlnj-c/trunk
1361 :    
1362 :     In $gf/admin there are a few useful shell scripts for checking out
1363 :     and maintaining the entire collection of trees:
1364 :    
1365 :     admin/checkout-all.sh [dir]
1366 :     -- optionally creates dir and checks out all trees from their
1367 :     default repositories; if dir is missing, checkout into .
1368 :     admin/refresh-all.sh [dir]
1369 :     -- looks at all trees (from the above list) in dir (default: .)
1370 :     and runs "svn update" if the tree exists and is under
1371 :     subversion control;
1372 :     non-existing or non-subversion trees are skipped
1373 :     admin/stat-all.sh [dir]
1374 :     -- like refresh-all.sh, but runs "svn stat" instead

1557 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1558 : blume 2155 at the time when config/preloads is processed, the library has to
1559 : mblume 1878 be referred to by another name. In 110.57 this would be
1560 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm

1617 :     Description:
1618 :    
1619 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1620 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1621 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1622 :     it. Instead, it has the status of "user code", so it should use
1623 :     $/basis.cm to refer to the Basis library. (At least that's true for
1624 :     the purpose of bootstrapping the previous change. In the future it
1625 :     might make sense to have versiontool.cm refer to
1626 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1627 :     compiler itself uses.)

1630 :     bindings in config/extrapathconfig.

1635 :     Tag: blume-22051115-libraries
1636 :     Description:
1637 :    
1638 :     This change affects the way the following libraries are tied into
1639 :     the system:
1640 :    
1641 :     $/basis.cm
1642 :     $/smlnj-lib.cm
1643 :     $/pp-lib.cm
1644 :     $/controls-lib.cm
1645 :     $/html-lib.cm
1646 :     $/ml-yacc-lib.cm
1647 :    
1648 :     These libraries are now internally (as seen from the source code
1649 :     of the implementation itself) known by the following names:
1650 :    
1651 :     $smlnj/basis/basis.cm
1652 :     $smlnj/smlnj-lib/smlnj-lib.cm
1653 :     $smlnj/smlnj-lib/pp-lib.cm
1654 :     $smlnj/smlnj-lib/controls-lib.cm
1655 :     $smlnj/smlnj-lib/html-lib.cm
1656 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1657 :    
1658 :     This makes it possible to work with code that requires different
1659 :     versions of these libraries, and which refers to these libraries using
1660 :     their "default" names (i.e., the first set of names above). In other
1661 :     words, one can un-define or re-define those default names without
1662 :     compromising the proper functioning of the compiler itself.
1663 :    
1664 :     A similar procedure had already been performed for several of the
1665 :     MLRISC libraries that are linked into the compiler. I did some
1666 :     cleanup on this code.
1667 :    
1668 :     A new file in the config directory (named extrapathconfig) is
1669 :     responsible for setting up path anchors that the compiler itself does
1670 :     not need, but that are typically required by user code.

1849 :     Tag: blume-20050516-redump-heap
1850 :     Description:
1851 :    
1852 :     Added mechanism for re-creating a heap file for the interactive system
1853 :     after configuration variables have been changed.
1854 :    
1855 :     CM.redump_heap : string -> unit
1856 :    
1857 :     This is much like SMLofNJ.exportML, but starting from the resulting
1858 : blume 2155 heap does not return to the caller of CM.redump_heap but
1859 : mblume 1792 restarts the interactive system from scratch. The original call of
1860 :     CM.redump_heap does not return but ends the interactive session.
1861 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1862 :    
1863 :     Internally, redump_heap winds the dynamic execution context back to
1864 :     the point where the original heap image was created and re-executes
1865 :     the heap image generation code in the boot code.

1981 :     Tag: blume-20050114-heap2exec
1982 :     Description:
1983 :    
1984 :     Implemented new (but still experimental) heap2exec facility. This is
1985 :     tested under Mac OS X and should work under Linux (will test shortly).
1986 :     It will probably also work on the Sparc (will test some time later).
1987 :    
1988 :     - removed old "HACKED_STANDALONE" hack from runtime
1989 :    
1990 :     To be able to test this, uncomment the request for "heap2asm" in
1991 :     config/targets prior to installation. (Notice that this is different
1992 :     from "heap2exec" mentioned below. Not a typo.)
1993 :    
1994 :     To perform an actual test, run the command
1995 :    
1996 :     $ bin/heap2exec heapfile execfile
1997 :    
1998 :     (You can put heap2exec on your shell's path.)
1999 :    
2000 :     For example, run
2001 :    
2002 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
2003 :    
2004 :     This will create a standalone executable called "mly" which you can
2005 :     then invoke directly as a command.

2032 :    
2033 :     * Fixed CM's incorrect assumption that the PPC is little-endian.

2150 :     Tag: blume-20041124-position
2151 :     Description:
2152 :    
2153 :     The compiler can now be compiled in a mode that makes structure Position
2154 :     equal to Int64. The default, however, is unchanged (Position = Int31)
2155 :     for the time being.
2156 :    
2157 :     To enable 64-bit positions, use the following procedure:
2158 :    
2159 :     1. Start sml
2160 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
2161 :     3. Type
2162 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
2163 :     4. Run CMB.make() as usual.
2164 :    
2165 :     This is barely tested. The only test so far was a little SML program
2166 :     counting the number of characters in an 8-gigabyte file by
2167 :     reading it character-by-character. That test was successful.
2168 :    
2169 :     In support of 64-bit positions, a number of new functions have been
2170 :     added to the runtime system.

2214 :     The date string is generated at bootstrap time (during makeml).
2215 :    
2216 :     - In a previous commit, fixed a minor issue with how polyequal is being
2217 :     translated. In particular, the code now "looks through" abstractions.
2218 :     This results in slightly fewer polyEqual warnings and hopefully slightly
2219 :     more efficient code. Important examples for where this matters are
2220 :     the new int64 and word64 types.

2235 :     Description:
2236 :    
2237 :     All the pieces of Word64 are now there, with the exception of the
2238 :     conversions from and to LargeWord. (Eventually these need to be identities,
2239 :     but for the time being they don't even make sense because LargeWord is
2240 :     32-bit wide.)
2241 :    
2242 :     Also started to add similar support for Int64, but major pieces of that
2243 :     are still missing.

2248 :     Tag: blume-20041111-word64
2249 :     Description:
2250 :    
2251 :     Structure Word64 is now (almost) complete, word literals and patterns
2252 :     seem to work. There are a few odd pieces missing. In particular,
2253 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2254 :     at the moment.
2255 :    
2256 :     Making Word64 official would mean that LargeWord becomes Word64. But
2257 :     this requires extreme care because most word-word conversions have to
2258 :     go through LargeWord, so making a mistake means loss of efficiency or
2259 :     worse. Eventually there will be a solution similar to (but actually
2260 :     simpler than) what I did with IntInf.

2296 :     - Default contents of config/srcarchiveurl uses $VERSION and
2297 :     normally does not have to be edited to reflect a version change.
2298 :    
2299 :     (As a result, a version change can be done by just editing
2300 :     config/version, the rest is now automatic.)

2340 :     Tag: blume-20041020-standalone-backtrace
2341 :     Description:
2342 :    
2343 :     Added a mechanism for getting back-trace information from standalone
2344 :     programs. Here is how it works:
2345 :    
2346 :     1. The part of the program from which you want to get backtrace
2347 :     information (usually the whole program) should be wrapped with
2348 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
2349 :     main program could be modified from something like
2350 :    
2351 :     fun main (pgm, args) = ...
2352 :    
2353 :     to
2354 :    
2355 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2356 :    
2357 :     2. To be able to access BackTrace.monitor, you have to add
2358 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
2359 :     main function.
2360 :    
2361 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2362 :     CM might have created in the past for your project).
2363 :    
2364 :     4. Build the system using this command line:
2365 :    
2366 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2367 :     myprog.cm MyProg.main myprog
2368 :    
2369 :     instead of the usual
2370 :    
2371 :     ml-build myprog.cm MyProg.main myprog
2372 :    
2373 :     I changed a library name:
2374 :    
2375 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2376 :    
2377 :     New libraries:
2378 :    
2379 :     $smlnj-tdp/back-trace.cm
2380 :     -- when loaded causes the back-trace plugin to be installed
2381 :     $smlnj-tdp/coverage.cm
2382 :     -- when loaded causes the coverage plugin to be installed

2398 :     Description:
2399 :    
2400 :     * Test coverage tool added!
2401 :     * Further reorganization of tracing-, debugging-, and profiling support:
2402 :    
2403 :     - moved original BTImp -- now called BackTrace -- into a separate
2404 :     library called $/trace-debug-profile.cm
2405 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2406 :     - only the instrumentation mechanism is now left in the compiler proper
2407 :     - BackTrace module is a plugin which is NOT plugged in by default
2408 :     - Coverage module is another such plugin
2409 :    
2410 :     To get the benefits of any of these plugin modules, the code in
2411 :     question must be compiled with tdp instrumentation turned on. This
2412 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2413 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2414 :    
2415 :     Plugins are selected at link time. (Pre-compiled instrumented code
2416 :     can be re-loaded with different plugins in effect.) When an
2417 :     instrumented module is linked, whatever plugins are at that time
2418 :     enabled will come into effect for that module.
2419 :    
2420 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2421 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2422 :     To enable the coverage plugin, load the same library and invoke
2423 :     Coverage.install().
2424 :    
2425 :     Back-traces are generated automatically on uncaught exceptions and
2426 :     when the code in question explicitly invokes BackTrace.trigger().
2427 :    
2428 :     Coverage (and execution frequency-) information must be queried
2429 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2520 :     Added hack to make slave mode work in the presence of the version
2521 :     tool. (Still, since the master does two passes over the code for
2522 :     CMB.make, the release number gets bumped twice when slaves are
2523 :     attached. I don't know if this is worth fixing...)

2529 :     Description:
2530 :    
2531 :     * Moved the "version" magic into its own little library under
2532 : mblume 1672 src/system/smlnj/internal. This avoids expensive reconstruction of
2533 :     a stable src/compiler/core.cm.
2534 : mblume 1639
2535 : mblume 1672 * At the same time, structure CompilerVersion is now known as
2536 :     structure SMLNJVersion.
2537 : mblume 1639
2538 :     * Arranged for the version tool to NOT kick in when rebuilding the system
2539 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
2540 :     Also, loading the versiontool does not work when rebuilding the system
2541 :     because CM is not properly initialized at that time.

2546 :     Tag: blume-20040929-autoversion
2547 :     Description:
2548 :    
2549 :     Implemented some CM magic to have
2550 :     file src/compiler/TopLevel/main/version.sml
2551 :     generated automagically.
2552 :     The version is taken from two files: config/version and config/release.
2553 :     The first is expected to contain a two-part version number such as 110.49.
2554 :     The second should contain a single number, but it may be missing.
2555 :    
2556 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2557 :     time the version tool is loaded (which is the first time you say CMB.make),
2558 :     then the tool will increment the value stored in config/release every
2559 :     time CMB.make is invoked.
2560 :    
2561 :     The binfile format is now insensitive to anything beyond the first
2562 :     two components of a version number, so bumping the release does not render
2563 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2564 :     during development without invalidating existing binfiles.
2565 :    
2566 :     In any case, every CMB.make updates the date information in version.sml.
2567 :     (This is the date that is printed in the banner.)

2580 :     Tag: blume-20040927-controls
2581 :     Description:
2582 :    
2583 :     Added two pieces of functionality to the Controls interface:
2584 :    
2585 :     1. val save'restore: 'a control -> unit -> unit
2586 :    
2587 :     grabs the current value of the control in stage 1 and restores it
2588 :     in stage 2.
2589 :    
2590 :     2. val set' : 'a control * 'a -> unit -> unit
2591 :    
2592 :     stores the given value into the control in stage 2 (i.e., delayed)
2593 :     but does all error checking in stage 1.
2594 :     (This is for string controls that need to do parse their argument --
2595 :     something that might fail. In some cases, notably in CM, one
2596 :     already knows the intended argument but wants to delay the actual
2597 :     assignment until a time when error recovery would be more difficult.)
2598 :    
2599 :     Changed the handling of controls in tool arguments to classes "sml" and
2600 :     "lazysml":
2601 :     - use Controls.save'restore as a more robust way of restoring the
2602 :     old value (in particular: without having to re-parse the string)
2603 :     - use controls to handle the "overload" keyword in the init group
2604 :     (I believe this change actually fixes a long-standing obscure bug.)

2609 :     Tag: blume-20040927-lazysml
2610 :     Description:
2611 :    
2612 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2613 :     difference to "sml" is that compilation is done with Control.lazysml
2614 :     set to true. A source of class "lazysml" is automatically recognized
2615 :     by a file name suffix of ".lml".
2616 :    
2617 :     In addition to the above feature, the original class "sml" now also
2618 :     supports a tool argument "lazy" which has the same effect. As a
2619 :     result, the following three lines are equivalent:
2620 :    
2621 :     foo.sml : lazysml
2622 :     foo.sml : sml (lazy)
2623 :     foo.sml (lazy)
2624 :    
2625 :     The setting goes into effect both during parsing and during
2626 :     compilation. The original setting is restored right after parsing and
2627 :     after compilation, respectively.
2628 :    
2629 :     In addition to all the above, there is also a general mechanism to set
2630 :     ANY of the "controls" that are available at the command line via
2631 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2632 :     apply as well. (In fact, "lazy" is implemented as a special case of
2633 :     the general mechanism.)
2634 :    
2635 :     The .cm file syntax uses a new keyword tool argument called "with".
2636 :     There are several ways of indicating the desired settings:
2637 :    
2638 :     foo.sml (with:parser.quotations=true)
2639 :     foo.sml (with:(name:parser.quotations value:true))
2640 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2641 :     foo.sml (with:(name1=value1 name2=value2 ...))
2642 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2643 :    
2644 :     etc.
2645 :    
2646 :     Another possible abbreviation is to leave out the =v or value:v part
2647 :     if the name refers to a boolean control (in which case the value is
2648 :     taken to be true). Thus, one could get lazy sml also by saying:
2649 :    
2650 :     foo.sml (with:parser.lazy-keyword=true)
2651 :     foo.sml (with:parser.lazy-keyword)
2652 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2653 :     foo.sml (with:(name:parser.lazy-keyword))

2913 :     Added C_UNION to c-calls/c-types.sml and updated the machinery
2914 :     (ml-nlffigen, cproto.sml) that conveys C function interface
2915 :     information to the code generator.
2916 :    
2917 :     However, the actual architecture-specific implementation of function
2918 :     arguments and results that are C unions is still not implemented.

3005 :     Description:
3006 :    
3007 :     Changed the interface of structures Timer and Unix to match the most
3008 :     recent Basis spec.
3009 :    
3010 :     In the case of Unix there still seems to be an open/weird issue:
3011 :    
3012 :     The {text,bin}{In,Out}streamOf functions are supposed to create
3013 :     fresh streams whenever they are called -- as opposed to have them
3014 :     return the same stream every time. This design is supposed to
3015 :     prevent space leaks caused by proc values hanging on to streams.
3016 :    
3017 :     The reap function, on the other hand, is supposed to close the
3018 :     streams. This cannot be done without having a handle on the
3019 :     stream in proc after all...
3020 :    
3021 :     I took the liberty to implement the following stopgap solution:
3022 :    
3023 :     The proc value hangs on to the most recently created stream(s).
3024 :     Reap closes those. If either or both of the two streams hadn't
3025 :     been created at all yet, then reap will close the corresponding
3026 :     file descriptors directly.
3027 :    
3028 :     PS: I don't understand the original space leak argument anymore. If
3029 :     a proc hangs on to the imperative stream, then I/O operations on those
3030 :     will advance the state of the cached stream and avoid the space leak.

3043 :     Tag: blume-20040525-group-owner
3044 :     Description:
3045 :    
3046 :     CM now ignores (but still accepts) the "owner" information in group
3047 :     descriptions. The owner of a group is its next enclosing
3048 :     library. Each group must have a unique owner. (There is a virtual
3049 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
3050 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
3051 :     and CM would check that such a declaration is correct. The new scheme
3052 :     is to have CM check that for each group there is precisely one owning
3053 :     library.
3054 :    
3055 :     The advantage of the new scheme is that the programmer no longer needs
3056 :     to maintain the somewhat annoying owner information. The downside is
3057 :     that CM cannot enforce the ownership rule across multiple runs of
3058 :     CM.make. Fortunately, enclosing the same group in two different
3059 :     libraries A and B which are not part of the same program does not
3060 :     cause real problems.

3079 :     Description:
3080 :    
3081 :     Arranged for ml-build to clean up after itself a little bit better.
3082 :     The script generates a temporary SML source file and compiles it using
3083 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
3084 :     gets rid of those at the end, so they don't accumulate under .cm.
3085 :    
3086 :     This required a minor change to install.sh because the name of the
3087 :     metadata directory (default: .cm) is actually configurable at
3088 :     installation time.

3106 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
3107 :     for the voluminous patch!
3108 :    
3109 :     (I have not tested this patch under win32 yet.)
3110 :    
3111 : mblume 1490 Here is David's e-mail:
3112 :    
3113 :     Hi,
3114 :    
3115 :     Attached to this email you find a diff against sml/nj 110.45
3116 :     that will enable socket support under Windows.
3117 :    
3118 :     To apply the patch (using unix or cygwin)
3119 :     1) gunzip runtime.diff.gz
3120 :     2) "cd" into "src/runtime" in the source tree of a fresh
3121 :     110.45 installation.
3122 :     3) patch -p 1 < [your/path/to]runtime.diff
3123 :    
3124 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
3125 :     I only ran a few tests for basic socket client functionality
3126 :     (which worked fine). Especially the functions that use ioctl
3127 : mblume 1490 are not tested at all and might not work (see below).
3128 :    
3129 :     I implemented this since we want to move to a newer version of sml/nj
3130 :     but need socket support in order to use it. This is the first time I
3131 :     even had a look at the sml/nj source, so please review my changes
3132 :     before making this part of the distribution! Here are a few issues
3133 : blume 2155 that I think might be better for someone to solve who is more
3134 : mblume 1490 familiar with the sml/nj source (and socket programming):
3135 :    
3136 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
3137 :     exception since I could not figure out what the windows equivalent
3138 :     of these functions is
3139 :    
3140 :     - In sockets-osdep.h there are a some #include statements that are
3141 :     only used in a few files that include sockets-osdep.h
3142 :    
3143 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
3144 :     does not process its return value since I don't know how to
3145 :     report an error upwards.
3146 :    
3147 :     - It would probably be good to have a call to WSACleanup() when
3148 : blume 2155 the library is unloaded (if there is such a possibility).
3149 : mblume 1490 Otherwise I think Windows will take care of this automatically
3150 :     when the process finishes.
3151 :    
3152 :     - I used ioctlsocket() as a replacement for ioctl() but I have
3153 :     no idea if that is actually the proper replacement on Windows.
3154 :    
3155 :     - All these issues are marked in the code by "FIXME" comments.
3156 :    
3157 : blume 2155 We use sml/nj extensively in our products and are quite happy
3158 :     with it. I hope this contribution will help you.
3159 : mblume 1490
3160 :     Keep up the good work!

3325 :     Description:
3326 :    
3327 :     Eliminated the "dont_move_libraries" directive in config/targets.
3328 :     (The mechanism was broken and could not be fixed easily. Moreover,
3329 :     there does not seem to be any reason not to move all libraries into
3330 :     lib during installation. I originally implemented this directive as a
3331 :     backward-compatibility feature when I first introduced the new CM.
3332 :     Now that things have been stable for a long time and going back to the
3333 :     old CM is not an option, there is no reason to keep it around.)

3382 :     Tag: blume-20030926-ppautoload
3383 :     Description:
3384 :    
3385 :     I modified the read-eval-print loop so that the autoloader gets
3386 :     invoked whenever the prettyprinter tries to look up a symbol that
3387 :     is not currently defined in the toplevel environment but which
3388 :     appears in CM's autoload registry. As a result, we see far fewer of
3389 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3390 :    
3391 :     In addition to this I tried to clean up some pieces of the Basis
3392 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3393 :     instances of these ?.Foo.Bar.xxx names from being printed.
3394 :    
3395 :     The mechanism that picks names for types still needs some work, though.
3396 :     (Right now it seems that if there is a type A.t which is defined to
3397 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3398 :     "?.B.u" although the perhaps more sensible solution would be to use
3399 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3400 :     a chain of DEFtycs not farther than there are corresponding toplevel
3401 :     names in the current environment.)

3407 :     Description:
3408 :    
3409 :     Another installer tweak: All the ML code for the installer is now
3410 :     compiled during CMB.make and put into a little library called
3411 :     $smlnj/installer.cm. The installation then simply invokes
3412 :    
3413 :     sml -m $smlnj/installer.cm
3414 :    
3415 :     and everything happens automagically.
3416 :    
3417 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3418 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3419 :     and BINDIR.
3420 :    
3421 :     The new scheme guarantees that the ML code responsible for the installation
3422 :     is in sync with the APIs of the main system. Also, the installer is
3423 :     somewhat faster because the installer script is precompiled.

3430 :    
3431 :     Added a signature SYNCHRONOUS_SOCKET to basis.cm. This is like SOCKET
3432 :     but excludes all non-blocking operations. Defined SOCKET (in Basis)
3433 :     and CML_SOCKET in terms of SYNCHRONOUS_SOCKET. Removed superfluous
3434 :     implementations of non-blocking operations from CML's Socket
3435 :     structure.

3440 :     Tag: blume-20030924-sockets
3441 :     Description:
3442 :    
3443 :     1. Fixed SOCKET API and implementation to match Basis spec.
3444 :     This required changing the internal representation of sockets to one
3445 :     that remembers (for each socket file descriptor) whether it is currently
3446 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3447 :     call is made only if the state actually needs to change).
3448 :    
3449 :     2. OS-specific details of sockets were moved into separate files, thus
3450 :     making it possible to unify the bulk of the socket implementations
3451 :     between Unix and Win32.
3452 :    
3453 :     3. CML's socket API changed accordingly.
3454 :     (Note that we need to remove non-blocking functions from this API
3455 :     since they are redundant in the case of CML!)
3456 :    
3457 :     4. CML's socket implementation now makes use of non-blocking functions
3458 :     provided by Basis, thus removing all OS-dependent code from this part
3459 :     of CML.
3460 :    
3461 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3574 :     Description:
3575 :    
3576 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3577 :     Modified config/install.bat to take advantage of it. Also modified
3578 :     config/install.sh (and called it config/new-install.sh) to take advantage
3579 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3580 :     independent.)
3581 :    
3582 :     The installer can now install everything under Win32
3583 :     as well as under *nix as long as it compiles.
3584 :    
3585 :     Other changes:
3586 :    
3587 :     - made CML compile again under Win32
3588 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3589 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3590 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3591 :     same as type int; under Win32 it isn't
3592 :     - fixed some slice-related problems in the win32-specific parts of CML
3593 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3594 :     (under Win32, the volume name is case-insensitive, and the
3595 :     OS.Path code compares volume names for equality)

3612 : mblume 1350 Description:
3613 :    
3614 :     1. Changed interface to vectors and arrays in Basis to match
3615 :     (draft) Basis spec.
3616 :     2. Added signatures and implementations of slices according to
3617 :     Basis spec.
3618 :     3. Edited source code throughout the system to make it compile again
3619 :     under 1. and 2. (In some cases code had to be added to have it
3620 :     match the new signatures.)
3621 :     4. MLRISC should be backward-compatible: the copies of the originals
3622 :     of files that needed to change under 3. were retained, the .cm files
3623 :     check the compiler version number and use old versions when
3624 :     appropriate.
3625 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3626 :     dirstream -> string option (in accordance with Basis spec).
3627 :     6. When generating code that counts lines, ml-lex used function
3628 :     CharVector.foldli, taking advantage of its old interface.
3629 :     This has been replaced with the corresponding code from
3630 :     CharVectorSlice. (html-lex must be re-lexed!)
3631 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3632 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3633 :     8. Removed temporary additions (fromInternal, toInternal) from the
3634 :     (now obsolete) IntInf in smlnj-lib/Util.
3635 :     9. Cleaned up structure Byte.
3636 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3637 :     Cleaned/corrected implementation of Date.
3638 :     (Still need to check for correctness; implement better canonicalizeDate.)
3639 :     11. Added "scan" to signature IEEE_REAL.
3640 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3641 :     mod and rem when second operand is 2 (for parity checks).]
3642 :     13. Changed representation of type Time.time, using a single IntInf.int
3643 :     value counting microseconds. This considerably simplified the
3644 :     implementation of structure Time. We now support negative time
3645 :     values; scan and fromString handle signs.
3646 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3647 :     ArraySlice).

3653 :     Description:
3654 :    
3655 :     This is a major update which comes with a version number bump
3656 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3657 :     and an implementation of IntInf in the Basis.
3658 :    
3659 :     There are a fairly large number of related changes and updates throughout
3660 :     the system:
3661 :    
3662 :     Basis:
3663 :     - Implemented IntInf.
3664 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3665 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3666 : mblume 1347 - Added FixedInt as a synonym for Int32.
3667 :    
3668 :     compiler:
3669 :     * Added support for a built-in intinf type.
3670 :     - literals
3671 :     - pattern matching
3672 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3673 :     - overloading on literals and operations
3674 :    
3675 :     This required adding a primitive type intinf, some additional
3676 :     primops, and implementations for several non-trivial intinf
3677 :     operations in Core. (The intinf type is completely abstract
3678 :     to the compiler; all operations get delegated back to the Core.)
3679 :    
3680 :     * Intinf equality is handled by polyequal. However, the compiler
3681 :     does not print its usual warning in this case (since polyequal
3682 :     is the right thing to do there).
3683 :    
3684 :     * Improved the organization of structure InlineT.
3685 :    
3686 :     * A word about conversion primops:
3687 :     If conversions involving intinf do not cancel out during
3688 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3689 : mblume 1347 Since all core access must be resolved already during the FLINT
3690 :     translate phase, it would be too late a the time of CPS contract
3691 : mblume 1348 to add new Core calls. For this reason, conversion primops
3692 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3693 :     they are supposed to convert, and 2. the Core function that

3695 : mblume 1348 eliminates a primop, then the associated Core function becomes
3696 :     dead and goes away. Intinf conversion primops that do not get
3697 :     eliminated by CPS contract get rewritten into calls of their
3698 :     core functions by a separate, new phase.

3739 :     Tag: blume-20030811-windows
3740 :     Description:
3741 :    
3742 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3743 :    
3744 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3745 :    
3746 :     This patch restores SML/NJ's ability to run under win32. There are a
3747 :     number of changes, including fixes for several bugs that had gone
3748 :     unnoticed until now:
3749 :    
3750 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3751 :     trying to run the win32 version from within cygwin.)
3752 :    
3753 :     - There are a number of simple .bat scripts that substitute for their
3754 :     corresponding Unix shell-scripts. (See below.)
3755 :    
3756 :     - The internals of ml-build have been modified slightly. The main
3757 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3758 :     using OS.Process.system, the ML process delegates this task back
3759 :     to the script. Otherwise problems arise in mixed environments such
3760 :     as Cygwin where scripts look and work like Unix scripts, but
3761 :     where OS.Process.system cannot run them.
3762 :    
3763 :     - In CM, the srcpath pickler used native pathname syntax -- which
3764 :     is incorrect in the case of cross-compilation. The new pickle format
3765 :     is independent of platform-specific naming conventions.
3766 :    
3767 :     - Path configuration files (such as lib/pathconfig) can now choose
3768 :     between native and standard syntax. Placing a line of the form
3769 :    
3770 :     standard!
3771 :    
3772 :     into the file causes all subsequent paths to be interpreted using
3773 :     CM standard pathname syntax (= Unix conventions); a line
3774 :    
3775 :     native!
3776 :    
3777 :     switches back to native style. This was needed so that
3778 :     path config files can be written portably, see src/system/pathconfig.
3779 :    
3780 :     - Runtime system:
3781 :    
3782 :     - win32-filesys.c: get_file_time and set_file_time now
3783 :     access modification time, not creation time.
3784 :    
3785 :     - I/O code made aware of new array representation.
3786 :    
3787 :     - Bug fixes in X86.prim.masm.
3788 :    
3789 :     - src/system/makeml made aware of win32. (For use under cygwin
3790 :     and other Unix-environments for windows.)
3791 :    
3792 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3793 :     which caused BinIO.inputAll to fail consistently.
3794 :    
3795 :     .bat scripts:
3796 :    
3797 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3798 :    
3799 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3800 :     applications (sml, ml-yacc, ml-lex).
3801 :     - ml-build.bat: analogous to ml-build.
3802 :     - config\install.bat: Analogous to config/install.sh. This requires
3803 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3804 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3805 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3806 :     and the bootfile hierarchy must have been unpacked under
3807 :     sml.boot.x86-win32.
3808 :     The script is very primitive and does a poor job at error checking.
3809 :     It only installs the base system, ml-lex, and ml-yacc. No other
3810 :     libraries are being installed (i.e., you get only those that
3811 :     are part of the compiler.)
3812 :     - link-sml.bat: analogous to .link-sml, but not currently used
3813 :    
3814 :     Unrelated bug fixes:
3815 :    
3816 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3817 :     types.
3818 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3819 :     otherwise.)

3843 :     Description:
3844 :    
3845 :     Two changes:
3846 :

3848 :     be treated as errors (default is false).
3849 :     2. Cleaned up the *entire* source tree so that CMB.make goes through

3856 :     Description:
3857 :    
3858 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3859 :    
3860 :     This mainly affects the quality of error messages. However, some
3861 :     of the code is now more straightforward than before. (Treatment of
3862 :     the above four constructs in translate.sml is much simpler than
3863 :     the "macro-expansion" that was going on before. Plus, the mach-
3864 :     compiler no longer gets invoked just to be able to compile an
3865 :     if-expression.)
3866 :    
3867 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3868 :     interactive loop.

3874 :     Description:
3875 :    
3876 : blume 2155 Ported the runtime system to cygwin, which uses the unix

3878 :    
3879 : blume 2155 o getnetbyname, getnetbyaddr: these functions seem to be missing in
3880 : allenleung 1327 the Cygwin library.
3881 :     o Ctrl-C handling may be flaky.
3882 :     o Windows system calls and Windows I/O are not supported.
3883 :    
3884 :     A new set of binfiles is located at:
3885 :    
3886 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3887 :    
3888 :     This is only needed for bootstrapping the cygwin version of smlnj.

3931 :     change their identity (e.g., by getting unlinked and recreated by some
3932 :     text editor such as vi). There might be a better/cheaper/cleaner way

4110 :     Tag: blume-20020520-controls
4111 :     Description:
4112 :    
4113 :     - Added ControlUtil structure to control-lib.cm.
4114 :     - Use it throughout.
4115 :     - Used Controls facility to define MLRISC controls (as opposed to
4116 :     registering MLRISC control ref cells with Controls after the fact)
4117 :     - Fixed messed-up controls priorities.
4118 :    
4119 :     * Removed again all the stuff from config/preloads that one wouldn't
4120 :     be able to preload at the time the initial heap image is built.
4121 :     (Many libraries, e.g., CML, do not exist yet at this time. The
4122 :     only libraries that can be preloaded via config/preloads are those
4123 :     that come bundled with the bootfiles.)

4129 :     Description:
4130 :    
4131 :     Added a lot of commented-out suggestions for things to be included
4132 :     in config/preloads.

4138 :     Description:
4139 :    
4140 :     o Made the mdl tool stuff compile and run again.
4141 :     o I've disabled all the stuff that depends on RTL specifications; they
4142 :     are all badly broken anyway.

4148 :     Description:
4149 :    
4150 :     0. John Reppy made several modifications to the SML/NJ library.
4151 :     In particular, there is a shiny new controls-lib.cm.
4152 :    
4153 :     1. Pushed new controls interface through compiler so that everything
4154 :     compiles again.
4155 :    
4156 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
4157 :     SML/NJ library (so that CML compiles again).
4158 :    
4159 :     3. Modified init scripts because XXX_DEFAULT environment variables
4160 :     are no longer with us. (Boot-time initialization is now done
4161 :     using the same environment variables that are also used for
4162 :     startup-time initialization of controls.)

4168 :     Description:
4169 :    
4170 :     All pseudo-ops emitted before the first segment declaration
4171 :     such as TEXT, DATA, and BSS directives are assumed to be global
4172 :     declarations and are emitted first in the assembly file. This is
4173 :     useful in a number of situations where one has pseudo-ops that are not
4174 :     specific to any segment, and also works around the constraint that one
4175 :     cannot have client pseudo-ops in the TEXT segment.
4176 :    
4177 :     Because no segment is associated with these declarations it is
4178 :     an error to allocate any space or objects before the first segment
4179 :     directive and an exception will be raised. However, we cannot make
4180 :     this check for client pseudo-ops.
4181 :    
4182 :     These top level declarations are a field in the CFG graph_info.
4183 :     In theory you can continue to add to this field after the CFG has been
4184 :     built -- provided you know what you are doing;-)
