640 :     Revision: 2650
641 :     Description:
642 :    
643 :     3rd merge of base from primop-branch-3 into the trunk.
644 :     Additional bug fixes included:
645 :    
646 :     * Timer.cpu_timer, etc. type printing corrected (by making
647 :     Timer have opaque sig constraint in basis/Implementation/timer.sml)
648 :     * Infinite loop in FLINT (tests/typing/tests/25.sml) (fix by

653 :     Date: 2007/05/31 11:40:00 CDT
654 :     Description:
655 :    
656 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
657 :    
658 :     Also, changed the handling of "no core access": When translate.sml
659 :     needs access to a core exception at a time when the core has not
660 :     been set up yet (this only happens when compiling system/smlnj/init/*),
661 :     then don't bother generating the corresponding tests.
662 :    
663 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
664 :     the exception. Unfortunately, that confuses the plambda type checker.
665 :     Moreover, it does not do any good, because at runtime we don't expect
666 :     such an exception to be ever raised. (The code in system/smlnj/init/*
667 :     has to be written very carefully with this in mind!)

679 :     Description:
680 :    
681 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
682 :     with an explicit test for zero division. This should fixes several
683 :     regressions and makes it possible for downstream optimization phases
684 :     to treat these operations as "pure" when they are applied to unsigned

699 : jhr 2613 Description:
700 :    
701 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
702 :     for bugs #1415 and #1416. We also now correctly handle format characters that
703 :     lie outside the specified set.

706 : blume 2610 Name: Matthias Blume (http://www.tti-c.org/blume/)
707 :     Date: 2007/05/23 22:30:00 CDT
708 :     Description:
709 :    
710 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
711 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
712 :    
713 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
714 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
715 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
716 :     while running CMB.make. The point is that the single symbol
717 :     NO_PLUGINS is definde in all three cases.)
718 :    
719 :     I changed the three locations within the sources that get compiled
720 :     during CMB.make where ml-yacc or ml-lex input is processed: When
721 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
722 :     is bypassed.
723 :    
724 :     When bootstrapping new versions of the compiler, there can be
725 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
726 :     are not available or otherwise not operational. In this case one can
727 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
728 :     do so, the following command should be issued at the interactive
729 :     prompt:
730 :    
731 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
732 :    
733 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
734 :     files that normally would be generated by ml-yacc and ml-lex.
735 :     (Copies of these files are in the repository.)

751 :     Description:
752 :    
753 :     Changed the installation mechanism for CM tool plugins. These are
754 :     just libaries and now get installed like ordinary libaries.
755 :    
756 :     There are now a number of new installation targets that give some
757 :     fine-grain control over what classes and suffixes are known, and what
758 :     they will map to.
759 :     See config/targets for details.
760 :    
761 :     The code that caused plugin installation as part of running a
762 :     tool's "build" script has been removed. (The build script is for
763 :     building, not for installing.)

768 :     Description:
769 :    
770 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
771 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
772 :     CM fail if a shell tool reports a non-success exit status. If
773 :     the control is set to true, then CM will press on after tool failures
774 :     in the event that the target files exist (even though they are
775 :     considered outdated). Turning the control to true can be useful for
776 :     bootstrapping.

780 :     Date: 2007/05/19
781 :     Description:
782 :    
783 :     Merge of ml-lpt revisions for 110.64.
784 :    
785 :     The name of several ml-lpt-lib modules has changed:
786 :     Repair => AntlrRepair
787 :     StreamPos => AntlrStreamPos
788 :     ErrHandlerFn => AntlrErrHandler
789 :     EBNF => AntlrEBNF
790 :    
791 :     The ml-antlr specification format has changed: declarations such as
792 :     %tokens and nonterminal definitions can occur *multiple* times in the
793 :     same specification. The semantics are such that each new declaration
794 :     extends the previous ones. This does not apply to %start or %name,
795 :     of course.
796 :    
797 :     Importing a grammar via %import now includes *all* declarations in from
798 :     the imported grammar, except for %name, %entry, and %start. Tokens
799 :     and nonterminals can be dropped using the new %dropping clause of the
800 :     %import directive; the separate %drop and %extend have been removed.
801 :    
802 :     We now allow optional type annotations on nonterminals, using the %nonterms
803 :     directive as in ml-yacc.
804 :    
805 :     The refcell construct is now implemented using SML's regular reference
806 :     cells, so the :== and !! notation has been deprecated.
807 :    
808 :     The ml-antlr tool now does much more checking of specifications, and
809 :     its error messages have been greatly improved. Error repair for
810 :     generated parsers has been completely rewritten, and is now both
811 :     much faster and more accurate.
812 :    
813 :     ml-ulex is now more lenient with escape codes (non-SML-standard
814 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
815 :     Also, character classes may now include a "-" character at the beginning
816 :     as is standard in most other regexp tools.
817 :    
818 :     All of these changes are documented in the user guide, which has
819 :     been updated and improved with this merge.

825 :     Description:
826 :    
827 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
828 :     Significant changes in FLINT and the front end, mostly having to do
829 :     with a reorganized system for handling primops. Various bug fixes
830 :     and improvements in printing signatures.

835 :     Description:
836 :    
837 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
838 :     The ml-antlr specification format has changed: declarations such as
839 :     %tokens and nonterminal definitions can occur *multiple* times in the
840 :     same specification. The semantics are such that each new declaration
841 :     extends the previous ones. Grammar extension constructs have also
842 :     changed. We now allow type annotations on nonterminals. Finally,
843 :     the refcell construct is now implemented using SML's regular reference
844 :     cells, so the :== and !! notation has been deprecated. All of these
845 :     changes will appear in the 110.64 user guide for ml-lpt.
846 :    
847 :     The ml-antlr tool now does much more checking of specifications, and
848 :     its error messages have been greatly improved. There has also been
849 :     some work on the error repair process for generated parsers, but this
850 :     will be further improved in 110.64.

856 :    
857 :     More Basis fixes: The Char.fromString (etc.) functions did not handle
858 :     the "\uxxxx" escape sequence. There is still an outstanding bug with

898 :    
899 :     Substantially changed the signature and implementation of AMD64
900 :     SVID. It now looks similar to the ia32 SVID, yet uses staged

938 :     Date: 2007/02/26
939 :     Description:
940 :    
941 :     Added preliminary support in MLRISC for Staged Allocation, a technique
942 :     for specifying calling conventions (see
943 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
944 :     Initially, we plan to use this code to generate C calls for the AMD64.
945 :    
946 :     The staged allocation code base resides in MLRISC/staged-allocation,
947 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

953 :    
954 :     Bug fix: when SaveCState was called with two values to save, a subsequent
955 :     GC could cause the RestoreCState to fail because the saved state had been
956 :     promoted to tagless pair.

1012 :     Description:
1013 :    
1014 :     Brought ml-lpt manual up-to-date with the code. Many minor
1015 :     improvements to the tools, and a few minor bugfixes. Prepared
1016 :     ml-lpt-lib for integration with new UTF8 structure. Changed
1017 :     the interface for creating streams in ml-ulex (we now support
1018 :     stream creation from several kinds of sources). Overall, the
1019 :     tools are now quite stable, and their interfaces are unlikely to
1020 :     change in a way that would break compatibility. More work,
1021 :     however, is needed in the documentation.

1026 :     Description:
1027 :    
1028 :     Implemented library installer. Moved CM plugin code for
1029 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
1030 :     their respective trees. Implemented CM plugin for ml-ulex
1031 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
1032 :     and ml-antlr.
1033 :    
1034 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
1035 :     CM tools. (It turns out to be too messy to do otherwise because
1036 :     there is too much code that during installation relies on the presence
1037 :     of these tools -- resulting in a tricky ordering problem.)

1041 : blume 2277 Date: 2007/01/30 11:05:00 CST
1042 :     Description:
1043 :    
1044 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
1045 :     Modified CM's startup code to use shiftArgs as it processes
1046 :     command line arguments. This way, the init code in each .sml-file
1047 :     or library that is mentioned at the top level will see only
1048 :     those arguments that have not yet been processed at this point.
1049 :     In other words, the init code can "seize control" and process the
1050 :     remaining command line.

1117 :     Description:
1118 :    
1119 :     Added code to CM's "standard shell tool" implementation which
1120 :     causes it to tolerate (with a warning) the situation where the shell
1121 :     command fails (e.g., due to the shell command's non-existence)
1122 :     as long as all target files exist.
1123 :    
1124 :     This makes it possible to, e.g., build ml-yacc from sources even if
1125 :     svn checkout messed up the time stamps on files in such a way that
1126 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
1127 :     be needed to re-process yacc.grm, but obviously it might not yet be
1128 :     available at that time.)

1137 :     in the SML Basis specification too.

1168 :     Description:
1169 :    
1170 :     New working release (110.60). NEW BOOTFILES!
1171 :    
1172 :     This is the first subversion-hosted release. There are also changes
1173 :     to the directory layout. Here is a table:
1174 :    
1175 :     (All pathnames are relative to the SML/NJ "root" directory.)
1176 :    
1177 :     config -> config
1178 :    
1179 :     src/cm -> base/cm
1180 :     src/compiler -> base/compiler
1181 :     src/runtime -> base/runtime
1182 :     src/system -> base/system
1183 :    
1184 :     src/cm/pgraph -> pgraph
1185 :    
1186 :     src/READMES -> base/READMES
1187 :     src/$notefile -> base/NOTES/$notefile
1188 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1189 :     MACOSXINSTALL WININSTALL
1190 :    
1191 :     src/smlnj-lib -> smlnj-lib
1192 :     src/MLRISC -> MLRISC
1193 :     ckit -> ckit
1194 :     src/cml -> cml
1195 :     src/eXene -> eXene
1196 :     src/heap2asm -> heap2asm
1197 :     src/lexgen -> lexgen
1198 :     src/ml-burg -> ml-burg
1199 :     src/ml-lex -> ml-lex
1200 :     src/ml-yacc -> ml-yacc
1201 :     src/ml-nlffi-lib -> nlffi/lib
1202 :     src/ml-nlffigen -> nlffi/gen
1203 :     src/smlnj-c -> smlnj-c
1204 :     src/tools/TraceDebugProf -> trace-debug-profile
1205 :    
1206 :     In addition, there is also a new
1207 :    
1208 :     ml-lpt
1209 :    
1210 :     directory containing two new program generator tools: ml-ulex and
1211 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1212 :     LL(k) parser generator). These tools are currently "beta-quality"
1213 :    
1214 :     The latest versios of the sources can now be obtained anonymously
1215 :     via subversion. For this, it is useful to first check out
1216 :    
1217 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1218 :    
1219 :     and put the resulting directory on your shell's PATH. This provides
1220 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
1221 :     and refresh-all.sh.
1222 :    
1223 :     To create a freshly checked-out copy of the sources, do
1224 :    
1225 :     checkout-all.sh [dir]
1226 :    
1227 :     where dir is the optional SML/NJ root directory (default is ".").
1228 :    
1229 :     This creates the above directory layout. Each subdirectory of
1230 :     the root is under individual subversion control. The stat-all.sh
1231 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
1232 :     each of these subtrees.

1236 : blume 2155 Date: 2006/11/02 12:20:00 CST
1237 :     Description:
1238 :    
1239 :     Reorganized directory layout.
1240 :    
1241 :     This is a temporary solution, more reorganization is to come.
1242 :    
1243 :     The basic idea is to have a number of toplevel trees, each corresponding
1244 :     to a well-defined part of the overall system. Each part can be
1245 :     maintained individually, even in separate source repositories,
1246 :     although currently we still serve everything out of the main
1247 :     smlnj-gforge tree.
1248 :    
1249 :     Installer and and scripts have been updated to reflect the new
1250 :     layout. The installer (base/src/system/smlnj/installer) is now
1251 :     "scriptable" to avoid burning too much knowledge about the
1252 :     layout into SML source code. The main script used by the installer
1253 :     is in config/actions.
1254 :    
1255 :     The main change is that many of the subdirectories of what used to
1256 :     be known as "src" have moved to the toplevel. The "src" directory
1257 :     itself has moved down into a subtree called "base". (We may eventually
1258 :     get rid of the extra level of indirection represented by "src".)
1259 :    
1260 :     The layout is now as follows:
1261 :    
1262 :     toplevel tree name | default repository
1263 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1264 :     -------------------+----------------------------------------------------
1265 :     config | $gf/config/trunk
1266 :     |
1267 :     base | $gf/sml/trunk
1268 :     |
1269 :     smlnj-lib | $gf/smlnj-lib/trunk
1270 :     MLRISC | $gf/MLRISC/trunk
1271 :     |
1272 :     ml-yacc | $gf/ml-yacc/trunk
1273 :     ml-lex | $gf/ml-lex/trunk
1274 :     ml-burg | $gf/ml-burg/trunk
1275 :     lexgen | $gf/lexgen/trunk
1276 :     heap2asm | $gf/heap2asm/trunk
1277 :     |
1278 :     cml | $gf/cml/trunk
1279 :     eXene | $gf/eXene/trunk
1280 :     ckit | $gf/ckit/trunk
1281 :     nlffi | $gf/nlffi/trunk
1282 :     |
1283 :     smlnj-c | $gf/smlnj-c/trunk
1284 :    
1285 :     In $gf/admin there are a few useful shell scripts for checking out
1286 :     and maintaining the entire collection of trees:
1287 :    
1288 :     admin/checkout-all.sh [dir]
1289 :     -- optionally creates dir and checks out all trees from their
1290 :     default repositories; if dir is missing, checkout into .
1291 :     admin/refresh-all.sh [dir]
1292 :     -- looks at all trees (from the above list) in dir (default: .)
1293 :     and runs "svn update" if the tree exists and is under
1294 :     subversion control;
1295 :     non-existing or non-subversion trees are skipped
1296 :     admin/stat-all.sh [dir]
1297 :     -- like refresh-all.sh, but runs "svn stat" instead

1443 :     Description:
1444 :    
1445 :     Hooked code for Darwin-specific Intel ABI into main compiler.
1446 :     (This is a temporary solution which relies on the fact that the
1447 :     compiler itself does not use NLFFI. Eventually we need to divorce
1448 :     intel mac from generic x86 unix code and make separate sets of binaries.)

1477 :     Description:
1478 :    
1479 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1480 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1481 : blume 2155 at the time when config/preloads is processed, the library has to
1482 : mblume 1878 be referred to by another name. In 110.57 this would be
1483 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1484 :     to be valid as well.)
1485 :

1504 :     the physical location of basis.cm has changed). Also, corrected the

1539 :     Tag: blume-22051115-versiontool
1540 :     Description:
1541 :    
1542 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1543 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1544 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1545 :     it. Instead, it has the status of "user code", so it should use
1546 :     $/basis.cm to refer to the Basis library. (At least that's true for
1547 :     the purpose of bootstrapping the previous change. In the future it
1548 :     might make sense to have versiontool.cm refer to
1549 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1550 :     compiler itself uses.)
1551 :    
1552 :     Also patched src/system/testml to have it activate those extra anchor
1553 :     bindings in config/extrapathconfig.

1558 :     Tag: blume-22051115-libraries
1559 :     Description:
1560 :    
1561 :     This change affects the way the following libraries are tied into
1562 :     the system:
1563 :    
1564 :     $/basis.cm
1565 :     $/smlnj-lib.cm
1566 :     $/pp-lib.cm
1567 :     $/controls-lib.cm
1568 :     $/html-lib.cm
1569 :     $/ml-yacc-lib.cm
1570 :    
1571 :     These libraries are now internally (as seen from the source code
1572 :     of the implementation itself) known by the following names:
1573 :    
1574 :     $smlnj/basis/basis.cm
1575 :     $smlnj/smlnj-lib/smlnj-lib.cm
1576 :     $smlnj/smlnj-lib/pp-lib.cm
1577 :     $smlnj/smlnj-lib/controls-lib.cm
1578 :     $smlnj/smlnj-lib/html-lib.cm
1579 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1580 :    
1581 :     This makes it possible to work with code that requires different
1582 :     versions of these libraries, and which refers to these libraries using
1583 :     their "default" names (i.e., the first set of names above). In other
1584 :     words, one can un-define or re-define those default names without
1585 :     compromising the proper functioning of the compiler itself.
1586 :    
1587 :     A similar procedure had already been performed for several of the
1588 :     MLRISC libraries that are linked into the compiler. I did some
1589 :     cleanup on this code.
1590 :    
1591 :     A new file in the config directory (named extrapathconfig) is
1592 :     responsible for setting up path anchors that the compiler itself does
1593 :     not need, but that are typically required by user code.

1754 :     Tag: blume-20050518-installer
1755 :     Description:
1756 :    
1757 :     Added support scripts for Mac OS X PackageMaker and modified
1758 :     config/install.sh so that it supports re-dumping a heap image
1759 :     after customization.

1772 :     Tag: blume-20050516-redump-heap
1773 :     Description:
1774 :    
1775 :     Added mechanism for re-creating a heap file for the interactive system
1776 :     after configuration variables have been changed.
1777 :    
1778 :     CM.redump_heap : string -> unit
1779 :    
1780 :     This is much like SMLofNJ.exportML, but starting from the resulting
1781 : blume 2155 heap does not return to the caller of CM.redump_heap but
1782 : mblume 1792 restarts the interactive system from scratch. The original call of
1783 :     CM.redump_heap does not return but ends the interactive session.
1784 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1785 :    
1786 :     Internally, redump_heap winds the dynamic execution context back to
1787 :     the point where the original heap image was created and re-executes
1788 :     the heap image generation code in the boot code.

1794 :     Description:
1795 :    
1796 :     Added a hack to the existing hack known as Word64 to make fromString
1797 :     behave correctly. I am still not sure whether Word64.scan will work
1798 :     as specified with respect to the interaction of radix and prefix.

1830 :     Description:
1831 :    
1832 :     Fixed serious bug (brown paper bag variety) in new implementation of
1833 :     structure Atom in CML. (I had accidentally used a mailbox instead of

1848 :     Description:
1849 :    
1850 :     Brought back SMLofNJ.Susp. The underlying suspension type is the one
1851 :     implemented in Core -- which means that it is the same as the one used
1852 :     by the lazy extension.

1876 :     Description:
1877 :    
1878 :     Implemented "long long" arguments and results for NLFFI. (Only the
1879 :     PPC/MacOS implementation is complete, the other backends still need to
1880 :     be updated.)

1886 :     Description:
1887 :

1904 :     Tag: blume-20050114-heap2exec
1905 :     Description:
1906 :    
1907 :     Implemented new (but still experimental) heap2exec facility. This is
1908 :     tested under Mac OS X and should work under Linux (will test shortly).
1909 :     It will probably also work on the Sparc (will test some time later).
1910 :    
1911 :     - removed old "HACKED_STANDALONE" hack from runtime
1912 :    
1913 :     To be able to test this, uncomment the request for "heap2asm" in
1914 :     config/targets prior to installation. (Notice that this is different
1915 :     from "heap2exec" mentioned below. Not a typo.)
1916 :    
1917 :     To perform an actual test, run the command
1918 :    
1919 :     $ bin/heap2exec heapfile execfile
1920 :    
1921 :     (You can put heap2exec on your shell's path.)
1922 :    
1923 :     For example, run
1924 :    
1925 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1926 :    
1927 :     This will create a standalone executable called "mly" which you can
1928 :     then invoke directly as a command.

1950 :     Description:
1951 :    
1952 :     * Implemented access to signed and unsigned long long data in NLFFI.
1953 :     (The parameter-passing part of the picture has not complete. But
1954 :     data structure access seems to work.)
1955 :    
1956 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1957 :     (On the Mac, it is big-endian. And that's currently our only
1958 :     PPC platform.)

1974 :     Description:
1975 :    
1976 : blume 2155 The Unix I/O library of SML/NJ on cygwin does not understand
1977 :     Windows style pathname, so problems arise when SMLNJ_HOME is set
1978 :     to a Windows style pathname. _run-sml now converts SMLNJ_HOME
1979 :     to a POSIX pathname on cygwin.

2073 :     Tag: blume-20041124-position
2074 :     Description:
2075 :    
2076 :     The compiler can now be compiled in a mode that makes structure Position
2077 :     equal to Int64. The default, however, is unchanged (Position = Int31)
2078 :     for the time being.
2079 :    
2080 :     To enable 64-bit positions, use the following procedure:
2081 :    
2082 :     1. Start sml
2083 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
2084 :     3. Type
2085 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
2086 :     4. Run CMB.make() as usual.
2087 :    
2088 :     This is barely tested. The only test so far was a little SML program
2089 :     counting the number of characters in an 8-gigabyte file by
2090 :     reading it character-by-character. That test was successful.
2091 :    
2092 :     In support of 64-bit positions, a number of new functions have been
2093 :     added to the runtime system.

2134 :     Description:
2135 :    
2136 :     - Stripped down the versiontool: It now only handles the version number.
2137 :     The date string is generated at bootstrap time (during makeml).
2138 :    
2139 :     - In a previous commit, fixed a minor issue with how polyequal is being
2140 :     translated. In particular, the code now "looks through" abstractions.
2141 :     This results in slightly fewer polyEqual warnings and hopefully slightly
2142 :     more efficient code. Important examples for where this matters are
2143 :     the new int64 and word64 types.

2158 :     Description:
2159 :    
2160 :     All the pieces of Word64 are now there, with the exception of the
2161 :     conversions from and to LargeWord. (Eventually these need to be identities,
2162 :     but for the time being they don't even make sense because LargeWord is
2163 :     32-bit wide.)
2164 :    
2165 :     Also started to add similar support for Int64, but major pieces of that
2166 :     are still missing.

2172 :     Description:
2173 :    
2174 :     Structure Word64 is now (almost) complete, word literals and patterns
2175 :     seem to work. There are a few odd pieces missing. In particular,
2176 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2177 :     at the moment.
2178 :    
2179 :     Making Word64 official would mean that LargeWord becomes Word64. But
2180 :     this requires extreme care because most word-word conversions have to
2181 :     go through LargeWord, so making a mistake means loss of efficiency or
2182 :     worse. Eventually there will be a solution similar to (but actually
2183 :     simpler than) what I did with IntInf.

2214 :    
2215 :     - Changend config/srcarchiveurl from a file just

2218 :     - Made corresponding changes to config/install.sh and config/unpack.
2219 :     - Default contents of config/srcarchiveurl uses $VERSION and
2220 :     normally does not have to be edited to reflect a version change.
2221 :    
2222 :     (As a result, a version change can be done by just editing
2223 :     config/version, the rest is now automatic.)

2263 :     Tag: blume-20041020-standalone-backtrace
2264 :     Description:
2265 :    
2266 :     Added a mechanism for getting back-trace information from standalone
2267 :     programs. Here is how it works:
2268 :    
2269 :     1. The part of the program from which you want to get backtrace
2270 :     information (usually the whole program) should be wrapped with
2271 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
2272 :     main program could be modified from something like
2273 :    
2274 :     fun main (pgm, args) = ...
2275 :    
2276 :     to
2277 :    
2278 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2279 :    
2280 :     2. To be able to access BackTrace.monitor, you have to add
2281 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
2282 :     main function.
2283 :    
2284 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2285 :     CM might have created in the past for your project).
2286 :    
2287 :     4. Build the system using this command line:
2288 :    
2289 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2290 :     myprog.cm MyProg.main myprog
2291 :    
2292 :     instead of the usual
2293 :    
2294 :     ml-build myprog.cm MyProg.main myprog
2295 :    
2296 :     I changed a library name:
2297 :    
2298 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2299 :    
2300 :     New libraries:
2301 :    
2302 :     $smlnj-tdp/back-trace.cm
2303 :     -- when loaded causes the back-trace plugin to be installed
2304 :     $smlnj-tdp/coverage.cm
2305 :     -- when loaded causes the coverage plugin to be installed

2321 :     Description:
2322 :    
2323 :     * Test coverage tool added!
2324 :     * Further reorganization of tracing-, debugging-, and profiling support:
2325 :    
2326 :     - moved original BTImp -- now called BackTrace -- into a separate
2327 :     library called $/trace-debug-profile.cm
2328 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2329 :     - only the instrumentation mechanism is now left in the compiler proper
2330 :     - BackTrace module is a plugin which is NOT plugged in by default
2331 :     - Coverage module is another such plugin
2332 :    
2333 :     To get the benefits of any of these plugin modules, the code in
2334 :     question must be compiled with tdp instrumentation turned on. This
2335 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2336 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2337 :    
2338 :     Plugins are selected at link time. (Pre-compiled instrumented code
2339 :     can be re-loaded with different plugins in effect.) When an
2340 :     instrumented module is linked, whatever plugins are at that time
2341 :     enabled will come into effect for that module.
2342 :    
2343 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2344 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2345 :     To enable the coverage plugin, load the same library and invoke
2346 :     Coverage.install().
2347 :    
2348 :     Back-traces are generated automatically on uncaught exceptions and
2349 :     when the code in question explicitly invokes BackTrace.trigger().
2350 :    
2351 :     Coverage (and execution frequency-) information must be queried
2352 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2373 :    
2374 :     This is is preparation of using the original back-trace
2375 :     instrumentation for other purposes. "TDP" stands for
2376 :     Trace/Debug/Profile.
2377 :    
2378 :     The control flag controlling whether instrumentation is on or off is now

2406 :    
2407 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool

2470 :     Description:
2471 :    
2472 :     Implemented some CM magic to have
2473 :     file src/compiler/TopLevel/main/version.sml
2474 :     generated automagically.
2475 :     The version is taken from two files: config/version and config/release.
2476 :     The first is expected to contain a two-part version number such as 110.49.
2477 :     The second should contain a single number, but it may be missing.
2478 :    
2479 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2480 :     time the version tool is loaded (which is the first time you say CMB.make),
2481 :     then the tool will increment the value stored in config/release every
2482 :     time CMB.make is invoked.
2483 :    
2484 :     The binfile format is now insensitive to anything beyond the first
2485 :     two components of a version number, so bumping the release does not render
2486 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2487 :     during development without invalidating existing binfiles.
2488 :    
2489 :     In any case, every CMB.make updates the date information in version.sml.

2516 :     but does all error checking in stage 1.
2517 :     (This is for string controls that need to do parse their argument --
2518 :     something that might fail. In some cases, notably in CM, one
2519 :     already knows the intended argument but wants to delay the actual
2520 :     assignment until a time when error recovery would be more difficult.)
2521 :    
2522 :     Changed the handling of controls in tool arguments to classes "sml" and
2523 :     "lazysml":
2524 :     - use Controls.save'restore as a more robust way of restoring the
2525 :     old value (in particular: without having to re-parse the string)
2526 :     - use controls to handle the "overload" keyword in the init group
2527 :     (I believe this change actually fixes a long-standing obscure bug.)

2532 :     Tag: blume-20040927-lazysml
2533 :     Description:
2534 :    
2535 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2536 :     difference to "sml" is that compilation is done with Control.lazysml
2537 :     set to true. A source of class "lazysml" is automatically recognized
2538 :     by a file name suffix of ".lml".
2539 :    
2540 :     In addition to the above feature, the original class "sml" now also
2541 :     supports a tool argument "lazy" which has the same effect. As a
2542 :     result, the following three lines are equivalent:
2543 :    
2544 :     foo.sml : lazysml
2545 :     foo.sml : sml (lazy)
2546 :     foo.sml (lazy)
2547 :    
2548 :     The setting goes into effect both during parsing and during
2549 :     compilation. The original setting is restored right after parsing and
2550 :     after compilation, respectively.
2551 :    
2552 :     In addition to all the above, there is also a general mechanism to set
2553 :     ANY of the "controls" that are available at the command line via
2554 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2555 :     apply as well. (In fact, "lazy" is implemented as a special case of
2556 :     the general mechanism.)
2557 :    
2558 :     The .cm file syntax uses a new keyword tool argument called "with".
2559 :     There are several ways of indicating the desired settings:
2560 :    
2561 :     foo.sml (with:parser.quotations=true)
2562 :     foo.sml (with:(name:parser.quotations value:true))
2563 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2564 :     foo.sml (with:(name1=value1 name2=value2 ...))
2565 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2566 :    
2567 :     etc.
2568 :    
2569 :     Another possible abbreviation is to leave out the =v or value:v part
2570 :     if the name refers to a boolean control (in which case the value is
2571 :     taken to be true). Thus, one could get lazy sml also by saying:
2572 :    
2573 :     foo.sml (with:parser.lazy-keyword=true)
2574 :     foo.sml (with:parser.lazy-keyword)
2575 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2576 :     foo.sml (with:(name:parser.lazy-keyword))

2908 :     Tag: blume-20040618-unix
2909 :     Description:
2910 :    
2911 :     Changed the implementation of structure Unix so that the same stream
2912 :     is returned every time one of the {text,bin}{In,Out}streamOf functions
2913 :     is invoked on the same proc. This is not what the spec currently
2914 :     says -- although IMO it arguably should. (See discussion below.)

2927 :     Tag: blume-20040617-timer-unix
2928 :     Description:
2929 :    
2930 :     Changed the interface of structures Timer and Unix to match the most
2931 :     recent Basis spec.
2932 :    
2933 :     In the case of Unix there still seems to be an open/weird issue:
2934 :    
2935 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2936 :     fresh streams whenever they are called -- as opposed to have them
2937 :     return the same stream every time. This design is supposed to
2938 :     prevent space leaks caused by proc values hanging on to streams.
2939 :    
2940 :     The reap function, on the other hand, is supposed to close the
2941 :     streams. This cannot be done without having a handle on the
2942 :     stream in proc after all...
2943 :    
2944 :     I took the liberty to implement the following stopgap solution:
2945 :    
2946 :     The proc value hangs on to the most recently created stream(s).
2947 :     Reap closes those. If either or both of the two streams hadn't
2948 :     been created at all yet, then reap will close the corresponding
2949 :     file descriptors directly.
2950 :    
2951 :     PS: I don't understand the original space leak argument anymore. If
2952 :     a proc hangs on to the imperative stream, then I/O operations on those
2953 :     will advance the state of the cached stream and avoid the space leak.

2966 :     Tag: blume-20040525-group-owner
2967 :     Description:
2968 :    
2969 :     CM now ignores (but still accepts) the "owner" information in group
2970 :     descriptions. The owner of a group is its next enclosing
2971 :     library. Each group must have a unique owner. (There is a virtual
2972 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
2973 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
2974 :     and CM would check that such a declaration is correct. The new scheme
2975 :     is to have CM check that for each group there is precisely one owning
2976 :     library.
2977 :    
2978 :     The advantage of the new scheme is that the programmer no longer needs
2979 :     to maintain the somewhat annoying owner information. The downside is
2980 :     that CM cannot enforce the ownership rule across multiple runs of
2981 :     CM.make. Fortunately, enclosing the same group in two different
2982 :     libraries A and B which are not part of the same program does not
2983 :     cause real problems.

3002 :     Description:
3003 :    
3004 :     Arranged for ml-build to clean up after itself a little bit better.
3005 :     The script generates a temporary SML source file and compiles it using
3006 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
3007 :     gets rid of those at the end, so they don't accumulate under .cm.
3008 :    
3009 :     This required a minor change to install.sh because the name of the
3010 :     metadata directory (default: .cm) is actually configurable at
3011 :     installation time.

3026 :     Description:
3027 :    
3028 :     Added previously missing support for many socket-related functions
3029 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
3030 :     for the voluminous patch!
3031 :    
3032 :     (I have not tested this patch under win32 yet.)
3033 :    
3034 : mblume 1490 Here is David's e-mail:
3035 :    
3036 :     Hi,
3037 :    
3038 :     Attached to this email you find a diff against sml/nj 110.45
3039 :     that will enable socket support under Windows.
3040 :    
3041 :     To apply the patch (using unix or cygwin)
3042 :     1) gunzip runtime.diff.gz
3043 :     2) "cd" into "src/runtime" in the source tree of a fresh
3044 :     110.45 installation.
3045 :     3) patch -p 1 < [your/path/to]runtime.diff
3046 :    
3047 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
3048 :     I only ran a few tests for basic socket client functionality
3049 :     (which worked fine). Especially the functions that use ioctl
3050 : mblume 1490 are not tested at all and might not work (see below).
3051 :    
3052 :     I implemented this since we want to move to a newer version of sml/nj
3053 :     but need socket support in order to use it. This is the first time I
3054 :     even had a look at the sml/nj source, so please review my changes
3055 :     before making this part of the distribution! Here are a few issues
3056 : blume 2155 that I think might be better for someone to solve who is more
3057 : mblume 1490 familiar with the sml/nj source (and socket programming):
3058 :    
3059 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
3060 :     exception since I could not figure out what the windows equivalent
3061 :     of these functions is
3062 :    
3063 :     - In sockets-osdep.h there are a some #include statements that are
3064 :     only used in a few files that include sockets-osdep.h
3065 :    
3066 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
3067 :     does not process its return value since I don't know how to
3068 :     report an error upwards.
3069 :    
3070 :     - It would probably be good to have a call to WSACleanup() when
3071 : blume 2155 the library is unloaded (if there is such a possibility).
3072 : mblume 1490 Otherwise I think Windows will take care of this automatically
3073 :     when the process finishes.
3074 :    
3075 :     - I used ioctlsocket() as a replacement for ioctl() but I have
3076 :     no idea if that is actually the proper replacement on Windows.
3077 :    
3078 :     - All these issues are marked in the code by "FIXME" comments.
3079 :    
3080 : blume 2155 We use sml/nj extensively in our products and are quite happy
3081 :     with it. I hope this contribution will help you.
3082 : mblume 1490
3083 :     Keep up the good work!

3167 :    
3168 : blume 2155 does not work on Windows unless we explicitly export symbols

3306 :     Description:
3307 :    
3308 :     I modified the read-eval-print loop so that the autoloader gets
3309 :     invoked whenever the prettyprinter tries to look up a symbol that
3310 :     is not currently defined in the toplevel environment but which
3311 :     appears in CM's autoload registry. As a result, we see far fewer of
3312 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3313 :    
3314 :     In addition to this I tried to clean up some pieces of the Basis
3315 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3316 :     instances of these ?.Foo.Bar.xxx names from being printed.
3317 :    
3318 :     The mechanism that picks names for types still needs some work, though.
3319 :     (Right now it seems that if there is a type A.t which is defined to
3320 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3321 :     "?.B.u" although the perhaps more sensible solution would be to use
3322 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3323 :     a chain of DEFtycs not farther than there are corresponding toplevel
3324 :     names in the current environment.)

3330 :     Description:
3331 :    
3332 :     Another installer tweak: All the ML code for the installer is now
3333 :     compiled during CMB.make and put into a little library called
3334 :     $smlnj/installer.cm. The installation then simply invokes
3335 :    
3336 :     sml -m $smlnj/installer.cm
3337 :    
3338 :     and everything happens automagically.
3339 :    
3340 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3341 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3342 :     and BINDIR.
3343 :    
3344 :     The new scheme guarantees that the ML code responsible for the installation
3345 :     is in sync with the APIs of the main system. Also, the installer is
3346 :     somewhat faster because the installer script is precompiled.

3354 :     Added a signature SYNCHRONOUS_SOCKET to basis.cm. This is like SOCKET
3355 :     but excludes all non-blocking operations. Defined SOCKET (in Basis)
3356 :     and CML_SOCKET in terms of SYNCHRONOUS_SOCKET. Removed superfluous

3358 :     structure.

3363 :     Tag: blume-20030924-sockets
3364 :     Description:
3365 :    
3366 :     1. Fixed SOCKET API and implementation to match Basis spec.
3367 :     This required changing the internal representation of sockets to one
3368 :     that remembers (for each socket file descriptor) whether it is currently
3369 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3370 :     call is made only if the state actually needs to change).
3371 :    
3372 :     2. OS-specific details of sockets were moved into separate files, thus
3373 :     making it possible to unify the bulk of the socket implementations
3374 :     between Unix and Win32.
3375 :    
3376 :     3. CML's socket API changed accordingly.
3377 :     (Note that we need to remove non-blocking functions from this API
3378 :     since they are redundant in the case of CML!)
3379 :    
3380 :     4. CML's socket implementation now makes use of non-blocking functions
3381 :     provided by Basis, thus removing all OS-dependent code from this part
3382 :     of CML.
3383 :    
3384 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3497 :     Description:
3498 :    
3499 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3500 :     Modified config/install.bat to take advantage of it. Also modified
3501 :     config/install.sh (and called it config/new-install.sh) to take advantage
3502 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3503 :     independent.)
3504 :    
3505 :     The installer can now install everything under Win32
3506 :     as well as under *nix as long as it compiles.
3507 :    
3508 :     Other changes:
3509 :    
3510 :     - made CML compile again under Win32
3511 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3512 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3513 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3514 :     same as type int; under Win32 it isn't
3515 :     - fixed some slice-related problems in the win32-specific parts of CML
3516 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3517 :     (under Win32, the volume name is case-insensitive, and the
3518 :     OS.Path code compares volume names for equality)

3535 : mblume 1350 Description:
3536 :    
3537 :     1. Changed interface to vectors and arrays in Basis to match
3538 :     (draft) Basis spec.
3539 :     2. Added signatures and implementations of slices according to
3540 :     Basis spec.
3541 :     3. Edited source code throughout the system to make it compile again
3542 :     under 1. and 2. (In some cases code had to be added to have it
3543 :     match the new signatures.)
3544 :     4. MLRISC should be backward-compatible: the copies of the originals
3545 :     of files that needed to change under 3. were retained, the .cm files
3546 :     check the compiler version number and use old versions when
3547 :     appropriate.
3548 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3549 :     dirstream -> string option (in accordance with Basis spec).
3550 :     6. When generating code that counts lines, ml-lex used function
3551 :     CharVector.foldli, taking advantage of its old interface.
3552 :     This has been replaced with the corresponding code from
3553 :     CharVectorSlice. (html-lex must be re-lexed!)
3554 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3555 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3556 :     8. Removed temporary additions (fromInternal, toInternal) from the
3557 :     (now obsolete) IntInf in smlnj-lib/Util.
3558 :     9. Cleaned up structure Byte.
3559 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3560 :     Cleaned/corrected implementation of Date.
3561 :     (Still need to check for correctness; implement better canonicalizeDate.)
3562 :     11. Added "scan" to signature IEEE_REAL.
3563 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3564 :     mod and rem when second operand is 2 (for parity checks).]
3565 :     13. Changed representation of type Time.time, using a single IntInf.int
3566 :     value counting microseconds. This considerably simplified the
3567 :     implementation of structure Time. We now support negative time
3568 :     values; scan and fromString handle signs.
3569 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3570 :     ArraySlice).

3576 :     Description:
3577 :    
3578 :     This is a major update which comes with a version number bump
3579 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3580 :     and an implementation of IntInf in the Basis.
3581 :    
3582 :     There are a fairly large number of related changes and updates throughout
3583 :     the system:
3584 :    
3585 :     Basis:
3586 :     - Implemented IntInf.
3587 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3588 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3589 : mblume 1347 - Added FixedInt as a synonym for Int32.
3590 :    
3591 :     compiler:
3592 :     * Added support for a built-in intinf type.
3593 :     - literals
3594 :     - pattern matching
3595 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3596 :     - overloading on literals and operations
3597 :    
3598 :     This required adding a primitive type intinf, some additional
3599 :     primops, and implementations for several non-trivial intinf
3600 :     operations in Core. (The intinf type is completely abstract
3601 :     to the compiler; all operations get delegated back to the Core.)
3602 :    
3603 :     * Intinf equality is handled by polyequal. However, the compiler
3604 :     does not print its usual warning in this case (since polyequal
3605 :     is the right thing to do there).
3606 :    
3607 :     * Improved the organization of structure InlineT.
3608 :    
3609 :     * A word about conversion primops:
3610 :     If conversions involving intinf do not cancel out during
3611 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3612 : mblume 1347 Since all core access must be resolved already during the FLINT
3613 :     translate phase, it would be too late a the time of CPS contract
3614 : mblume 1348 to add new Core calls. For this reason, conversion primops
3615 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3616 :     they are supposed to convert, and 2. the Core function that
3617 :     can help with this conversion if necessary. If CPS contract
3618 : mblume 1348 eliminates a primop, then the associated Core function becomes
3619 :     dead and goes away. Intinf conversion primops that do not get
3620 :     eliminated by CPS contract get rewritten into calls of their
3621 :     core functions by a separate, new phase.
3622 : mblume 1347
3623 :     interactive system:
3624 :     - Control.Print.intinfDepth controls max length of intinf constants
3625 :     being printed. (Analogous to Control.Print.stringDepth.)
3626 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3627 :     duplicates; replaced some of the code with code that makes better
3628 :     use of library functionality.
3629 :    
3630 :     CM:
3631 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3632 :     are no longer silent.
3633 :    
3634 :     CKIT:
3635 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3636 :     in favor of LargeInt -- which is now the same as IntInf.
3637 :     CKIT-knowledgable people should check whether this is what's
3638 :     intended and otherwise change things back to using Int32 or
3639 :     FixedInt.
3640 :    
3641 :     Throughout the code:
3642 : mblume 1348 Started using IntInf.int literals and built-in operations
3643 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3667 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3668 :    
3669 :     This patch restores SML/NJ's ability to run under win32. There are a
3670 :     number of changes, including fixes for several bugs that had gone
3671 :     unnoticed until now:
3672 :    
3673 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3674 :     trying to run the win32 version from within cygwin.)
3675 :    
3676 :     - There are a number of simple .bat scripts that substitute for their
3677 :     corresponding Unix shell-scripts. (See below.)
3678 :    
3679 :     - The internals of ml-build have been modified slightly. The main
3680 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3681 :     using OS.Process.system, the ML process delegates this task back
3682 :     to the script. Otherwise problems arise in mixed environments such
3683 :     as Cygwin where scripts look and work like Unix scripts, but
3684 :     where OS.Process.system cannot run them.
3685 :    
3686 :     - In CM, the srcpath pickler used native pathname syntax -- which
3687 :     is incorrect in the case of cross-compilation. The new pickle format
3688 :     is independent of platform-specific naming conventions.
3689 :    
3690 :     - Path configuration files (such as lib/pathconfig) can now choose
3691 :     between native and standard syntax. Placing a line of the form
3692 :    
3693 :     standard!
3694 :    
3695 :     into the file causes all subsequent paths to be interpreted using
3696 :     CM standard pathname syntax (= Unix conventions); a line
3697 :    
3698 :     native!
3699 :    
3700 :     switches back to native style. This was needed so that
3701 :     path config files can be written portably, see src/system/pathconfig.
3702 :    
3703 :     - Runtime system:
3704 :    
3705 :     - win32-filesys.c: get_file_time and set_file_time now
3706 :     access modification time, not creation time.
3707 :    
3708 :     - I/O code made aware of new array representation.
3709 :    
3710 :     - Bug fixes in X86.prim.masm.
3711 :    
3712 :     - src/system/makeml made aware of win32. (For use under cygwin
3713 :     and other Unix-environments for windows.)
3714 :    
3715 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3716 :     which caused BinIO.inputAll to fail consistently.
3717 :    
3718 :     .bat scripts:
3719 :    
3720 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3721 :    
3722 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3723 :     applications (sml, ml-yacc, ml-lex).
3724 :     - ml-build.bat: analogous to ml-build.
3725 :     - config\install.bat: Analogous to config/install.sh. This requires
3726 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3727 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3728 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3729 :     and the bootfile hierarchy must have been unpacked under
3730 :     sml.boot.x86-win32.
3731 :     The script is very primitive and does a poor job at error checking.
3732 :     It only installs the base system, ml-lex, and ml-yacc. No other
3733 :     libraries are being installed (i.e., you get only those that
3734 :     are part of the compiler.)
3735 :     - link-sml.bat: analogous to .link-sml, but not currently used
3736 :    
3737 :     Unrelated bug fixes:
3738 :    
3739 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3740 :     types.
3741 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3742 :     otherwise.)

3767 :    
3768 :     Two changes:

3771 :     be treated as errors (default is false).

3779 :     Description:
3780 :    
3781 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3782 :    
3783 :     This mainly affects the quality of error messages. However, some
3784 :     of the code is now more straightforward than before. (Treatment of
3785 :     the above four constructs in translate.sml is much simpler than
3786 :     the "macro-expansion" that was going on before. Plus, the mach-
3787 :     compiler no longer gets invoked just to be able to compile an
3788 :     if-expression.)
3789 :    
3790 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3791 :     interactive loop.

3798 :    
3799 : blume 2155 Ported the runtime system to cygwin, which uses the unix
3800 : allenleung 1327 x86-unix bin files. Missing/buggy features:
3801 :    
3802 : blume 2155 o getnetbyname, getnetbyaddr: these functions seem to be missing in
3803 : allenleung 1327 the Cygwin library.
3804 :     o Ctrl-C handling may be flaky.
3805 :     o Windows system calls and Windows I/O are not supported.
3806 :    
3807 :     A new set of binfiles is located at:
3808 :    
3809 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3810 :    
3811 :     This is only needed for bootstrapping the cygwin version of smlnj.

3873 :     to patch 110.42 after the fact. The old release tag has been replaced
3874 :     (see below).

3911 :     the entire tree to some other place and everything will "just work".

3967 :    
3968 :     Another small change is that ppDec tries to give more information
3969 :     than just "<sig>" in the case of functors. However, this code is
3970 :     broken in some mysterious way if the functor's body's signature
3971 :     has not been declared by ascription but gets inferred from the

4073 :     0. John Reppy made several modifications to the SML/NJ library.
4074 :     In particular, there is a shiny new controls-lib.cm.
4075 :    
4076 :     1. Pushed new controls interface through compiler so that everything

4078 :

4091 :     Description:
4092 :    
4093 :     All pseudo-ops emitted before the first segment declaration
4094 :     such as TEXT, DATA, and BSS directives are assumed to be global
4095 :     declarations and are emitted first in the assembly file. This is
4096 :     useful in a number of situations where one has pseudo-ops that are not
4097 :     specific to any segment, and also works around the constraint that one
4098 :     cannot have client pseudo-ops in the TEXT segment.
4099 :    
4100 :     Because no segment is associated with these declarations it is
4101 :     an error to allocate any space or objects before the first segment
4102 :     directive and an exception will be raised. However, we cannot make
4103 :     this check for client pseudo-ops.
4104 :    
4105 :     These top level declarations are a field in the CFG graph_info.
4106 :     In theory you can continue to add to this field after the CFG has been
4107 :     built -- provided you know what you are doing;-)

4113 :     Description:
4114 :    
4115 :     A few minor bugfixes:
4116 :    
4117 :     - Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
4118 :     (Bogus printouts for redefined bindings still occur. Compiler
4119 :     bug should no longer occur now. We need to redo the prettyprinter
4120 :     from scratch.)
4121 :    
4122 :     - CM pathname printer now also adds escape sequences for ( and )
4123 :    
4124 :     - commend and docu fixes for ml-nlffi

4130 :     Description:
4131 :    
4132 :     Applied the following bugfix provided by Emden Gansner:
4133 :    
4134 :     Output is corrupted when outputSubstr is used rather than output.
4135 :    
4136 : blume 2155 The problem occurs when a substring
4137 : blume 1189
4138 :     ss = (s, dataStart, dataLen)
4139 :    
4140 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
4141 :     avail bytes of s, starting at index dataStart, are copied into the
4142 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
4143 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
4144 :     starting this copy at index dataStart+avail in s, the current code
4145 : blume 1189 starts the copy at index avail.
4146 :    
4147 :     Fix:
4148 :     In text-io-fn.sml, change line 695 from
4149 :     val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
4150 : blume 2155 to
4151 : blume 1189 val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

4157 :     Description:
4158 :    
4159 :     1. Grabbed newer assyntax.h from the XFree86 project.
4160 :     2. Fiddled with how to compile X86.prim.asm without warnings.
4161 :     3. (Very) Minor cleanup in CM.

4166 :     Tag: blume-20020401-x86div
4167 :     Description:
4168 :    
4169 :     Added full support for div/mod/rem/quot on the x86, using the machine
4170 :     instruction's two results (without clumsily recomputing the remainder)
4171 :     directly where appropriate.
4172 :    
4173 :     Some more extensive power-of-two support was added to the x86 instruction
4174 :     selector (avoiding expensive divs, mods, and muls where they can be
4175 :     replaced with cheaper shifts and masks). However, this sort of thing
4176 :     ought to be done earlier, e.g., within the CPS optimizer so that
4177 :     all architectures benefit from it.
4178 :    
4179 :     The compiler compiles to a fixed point, but changes might be somewhat
4180 :     fragile nevertheless. Please, report any strange things that you might
4181 :     see wrt. div/mod/quot/rem...
