680 :     Description:
681 :    
682 :     3rd merge of base from primop-branch-3 into the trunk.
683 :     Additional bug fixes included:
684 :    
685 :     * Timer.cpu_timer, etc. type printing corrected (by making

693 :     Description:
694 :    
695 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
696 :    
697 :     Also, changed the handling of "no core access": When translate.sml
698 :     needs access to a core exception at a time when the core has not
699 :     been set up yet (this only happens when compiling system/smlnj/init/*),
700 :     then don't bother generating the corresponding tests.
701 :    
702 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
703 :     the exception. Unfortunately, that confuses the plambda type checker.
704 :     Moreover, it does not do any good, because at runtime we don't expect
705 :     such an exception to be ever raised. (The code in system/smlnj/init/*
706 :     has to be written very carefully with this in mind!)

718 :     Description:
719 :    
720 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
721 :     with an explicit test for zero division. This should fixes several
722 :     regressions and makes it possible for downstream optimization phases
723 :     to treat these operations as "pure" when they are applied to unsigned

730 :

739 :    
740 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes

746 :     Date: 2007/05/23 22:30:00 CDT
747 :     Description:
748 :    
749 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
750 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
751 :    
752 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
753 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
754 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
755 :     while running CMB.make. The point is that the single symbol
756 :     NO_PLUGINS is definde in all three cases.)
757 :    
758 :     I changed the three locations within the sources that get compiled
759 :     during CMB.make where ml-yacc or ml-lex input is processed: When
760 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
761 :     is bypassed.
762 :    
763 :     When bootstrapping new versions of the compiler, there can be
764 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
765 :     are not available or otherwise not operational. In this case one can
766 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
767 :     do so, the following command should be issued at the interactive
768 :     prompt:
769 :    
770 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
771 :    
772 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
773 :     files that normally would be generated by ml-yacc and ml-lex.
774 :     (Copies of these files are in the repository.)

790 :     Description:
791 :    
792 :     Changed the installation mechanism for CM tool plugins. These are
793 :     just libaries and now get installed like ordinary libaries.
794 :    
795 :     There are now a number of new installation targets that give some
796 :     fine-grain control over what classes and suffixes are known, and what
797 :     they will map to.
798 :     See config/targets for details.
799 :    
800 :     The code that caused plugin installation as part of running a
801 :     tool's "build" script has been removed. (The build script is for
802 :     building, not for installing.)

807 :     Description:
808 :    
809 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
810 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
811 :     CM fail if a shell tool reports a non-success exit status. If
812 :     the control is set to true, then CM will press on after tool failures
813 :     in the event that the target files exist (even though they are
814 :     considered outdated). Turning the control to true can be useful for
815 :     bootstrapping.

820 :     Description:
821 :    
822 :     Merge of ml-lpt revisions for 110.64.
823 :    
824 :     The name of several ml-lpt-lib modules has changed:
825 :     Repair => AntlrRepair
826 :     StreamPos => AntlrStreamPos
827 :     ErrHandlerFn => AntlrErrHandler
828 :     EBNF => AntlrEBNF
829 :    
830 :     The ml-antlr specification format has changed: declarations such as
831 :     %tokens and nonterminal definitions can occur *multiple* times in the
832 :     same specification. The semantics are such that each new declaration
833 :     extends the previous ones. This does not apply to %start or %name,
834 :     of course.
835 :    
836 :     Importing a grammar via %import now includes *all* declarations in from
837 :     the imported grammar, except for %name, %entry, and %start. Tokens
838 :     and nonterminals can be dropped using the new %dropping clause of the
839 :     %import directive; the separate %drop and %extend have been removed.
840 :    
841 :     We now allow optional type annotations on nonterminals, using the %nonterms
842 :     directive as in ml-yacc.
843 :    
844 :     The refcell construct is now implemented using SML's regular reference
845 :     cells, so the :== and !! notation has been deprecated.
846 :    
847 :     The ml-antlr tool now does much more checking of specifications, and
848 :     its error messages have been greatly improved. Error repair for
849 :     generated parsers has been completely rewritten, and is now both
850 :     much faster and more accurate.
851 :    
852 :     ml-ulex is now more lenient with escape codes (non-SML-standard
853 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
854 :     Also, character classes may now include a "-" character at the beginning
855 :     as is standard in most other regexp tools.
856 :    
857 :     All of these changes are documented in the user guide, which has
858 :     been updated and improved with this merge.

874 :     Description:
875 :    
876 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
877 :     The ml-antlr specification format has changed: declarations such as
878 :     %tokens and nonterminal definitions can occur *multiple* times in the
879 :     same specification. The semantics are such that each new declaration
880 :     extends the previous ones. Grammar extension constructs have also

882 :     the refcell construct is now implemented using SML's regular reference
883 :     cells, so the :== and !! notation has been deprecated. All of these
884 :     changes will appear in the 110.64 user guide for ml-lpt.
885 :    
886 :     The ml-antlr tool now does much more checking of specifications, and
887 :     its error messages have been greatly improved. There has also been
888 :     some work on the error repair process for generated parsers, but this
889 :     will be further improved in 110.64.

895 :    
896 :     More Basis fixes: The Char.fromString (etc.) functions did not handle
897 :     the "\uxxxx" escape sequence. There is still an outstanding bug with
898 :     String.fromString the tail is a format escape. I added a comment to

977 :     Date: 2007/02/26
978 :     Description:
979 :    
980 :     Added preliminary support in MLRISC for Staged Allocation, a technique
981 :     for specifying calling conventions (see
982 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
983 :     Initially, we plan to use this code to generate C calls for the AMD64.
984 :    
985 :     The staged allocation code base resides in MLRISC/staged-allocation,
986 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

1051 :     Description:
1052 :    
1053 :     Brought ml-lpt manual up-to-date with the code. Many minor
1054 :     improvements to the tools, and a few minor bugfixes. Prepared
1055 :     ml-lpt-lib for integration with new UTF8 structure. Changed
1056 :     the interface for creating streams in ml-ulex (we now support
1057 :     stream creation from several kinds of sources). Overall, the
1058 :     tools are now quite stable, and their interfaces are unlikely to
1059 :     change in a way that would break compatibility. More work,
1060 :     however, is needed in the documentation.

1065 :     Description:
1066 :    
1067 :     Implemented library installer. Moved CM plugin code for
1068 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
1069 :     their respective trees. Implemented CM plugin for ml-ulex
1070 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
1071 :     and ml-antlr.
1072 :    
1073 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
1074 :     CM tools. (It turns out to be too messy to do otherwise because
1075 :     there is too much code that during installation relies on the presence
1076 :     of these tools -- resulting in a tricky ordering problem.)

1081 :     Description:
1082 :    
1083 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
1084 :     Modified CM's startup code to use shiftArgs as it processes
1085 :     command line arguments. This way, the init code in each .sml-file
1086 :     or library that is mentioned at the top level will see only
1087 :     those arguments that have not yet been processed at this point.
1088 :     In other words, the init code can "seize control" and process the
1089 :     remaining command line.

1156 :     Description:
1157 :    
1158 :     Added code to CM's "standard shell tool" implementation which
1159 :     causes it to tolerate (with a warning) the situation where the shell
1160 :     command fails (e.g., due to the shell command's non-existence)
1161 :     as long as all target files exist.
1162 :    
1163 :     This makes it possible to, e.g., build ml-yacc from sources even if
1164 :     svn checkout messed up the time stamps on files in such a way that
1165 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
1166 :     be needed to re-process yacc.grm, but obviously it might not yet be
1167 :     available at that time.)

1173 :    
1174 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
1175 :     recvVecFromNB' in the SOCKET signature. This error is actually
1176 :     in the SML Basis specification too.

1208 :    
1209 :     New working release (110.60). NEW BOOTFILES!
1210 :    
1211 :     This is the first subversion-hosted release. There are also changes
1212 :     to the directory layout. Here is a table:
1213 :    
1214 :     (All pathnames are relative to the SML/NJ "root" directory.)
1215 :    
1216 :     config -> config
1217 :    
1218 :     src/cm -> base/cm
1219 :     src/compiler -> base/compiler
1220 :     src/runtime -> base/runtime
1221 :     src/system -> base/system
1222 :    
1223 :     src/cm/pgraph -> pgraph
1224 :    
1225 :     src/READMES -> base/READMES
1226 :     src/$notefile -> base/NOTES/$notefile
1227 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1228 :     MACOSXINSTALL WININSTALL
1229 :    
1230 :     src/smlnj-lib -> smlnj-lib
1231 :     src/MLRISC -> MLRISC
1232 :     ckit -> ckit
1233 :     src/cml -> cml
1234 :     src/eXene -> eXene
1235 :     src/heap2asm -> heap2asm
1236 :     src/lexgen -> lexgen
1237 :     src/ml-burg -> ml-burg
1238 :     src/ml-lex -> ml-lex
1239 :     src/ml-yacc -> ml-yacc
1240 :     src/ml-nlffi-lib -> nlffi/lib
1241 :     src/ml-nlffigen -> nlffi/gen
1242 :     src/smlnj-c -> smlnj-c
1243 :     src/tools/TraceDebugProf -> trace-debug-profile
1244 :    
1245 :     In addition, there is also a new
1246 :    
1247 :     ml-lpt
1248 :    
1249 :     directory containing two new program generator tools: ml-ulex and
1250 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1251 :     LL(k) parser generator). These tools are currently "beta-quality"
1252 :    
1253 :     The latest versios of the sources can now be obtained anonymously
1254 :     via subversion. For this, it is useful to first check out
1255 :    
1256 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1257 :    
1258 :     and put the resulting directory on your shell's PATH. This provides
1259 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
1260 :     and refresh-all.sh.
1261 :    
1262 :     To create a freshly checked-out copy of the sources, do
1263 :    
1264 :     checkout-all.sh [dir]
1265 :    
1266 :     where dir is the optional SML/NJ root directory (default is ".").
1267 :    
1268 :     This creates the above directory layout. Each subdirectory of
1269 :     the root is under individual subversion control. The stat-all.sh
1270 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
1271 :     each of these subtrees.

1275 : blume 2155 Date: 2006/11/02 12:20:00 CST
1276 :     Description:
1277 :    
1278 :     Reorganized directory layout.
1279 :    
1280 :     This is a temporary solution, more reorganization is to come.
1281 :    
1282 :     The basic idea is to have a number of toplevel trees, each corresponding
1283 :     to a well-defined part of the overall system. Each part can be
1284 :     maintained individually, even in separate source repositories,
1285 :     although currently we still serve everything out of the main
1286 :     smlnj-gforge tree.
1287 :    
1288 :     Installer and and scripts have been updated to reflect the new
1289 :     layout. The installer (base/src/system/smlnj/installer) is now
1290 :     "scriptable" to avoid burning too much knowledge about the
1291 :     layout into SML source code. The main script used by the installer
1292 :     is in config/actions.
1293 :    
1294 :     The main change is that many of the subdirectories of what used to
1295 :     be known as "src" have moved to the toplevel. The "src" directory
1296 :     itself has moved down into a subtree called "base". (We may eventually
1297 :     get rid of the extra level of indirection represented by "src".)
1298 :    
1299 :     The layout is now as follows:
1300 :    
1301 :     toplevel tree name | default repository
1302 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1303 :     -------------------+----------------------------------------------------

1483 :    
1484 :     Hooked code for Darwin-specific Intel ABI into main compiler.
1485 :     (This is a temporary solution which relies on the fact that the

1516 :     Description:
1517 :    
1518 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1519 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1520 : blume 2155 at the time when config/preloads is processed, the library has to
1521 : mblume 1878 be referred to by another name. In 110.57 this would be
1522 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1523 :     to be valid as well.)

1579 :     Description:
1580 :    
1581 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1582 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1583 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1584 :     it. Instead, it has the status of "user code", so it should use
1585 :     $/basis.cm to refer to the Basis library. (At least that's true for
1586 :     the purpose of bootstrapping the previous change. In the future it
1587 :     might make sense to have versiontool.cm refer to
1588 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1589 :     compiler itself uses.)
1590 :    
1591 :     Also patched src/system/testml to have it activate those extra anchor
1592 :     bindings in config/extrapathconfig.

1597 :     Tag: blume-22051115-libraries
1598 :     Description:
1599 :    
1600 :     This change affects the way the following libraries are tied into
1601 :     the system:
1602 :    
1603 :     $/basis.cm
1604 :     $/smlnj-lib.cm
1605 :     $/pp-lib.cm
1606 :     $/controls-lib.cm
1607 :     $/html-lib.cm
1608 :     $/ml-yacc-lib.cm
1609 :    
1610 :     These libraries are now internally (as seen from the source code
1611 :     of the implementation itself) known by the following names:
1612 :    
1613 :     $smlnj/basis/basis.cm
1614 :     $smlnj/smlnj-lib/smlnj-lib.cm
1615 :     $smlnj/smlnj-lib/pp-lib.cm
1616 :     $smlnj/smlnj-lib/controls-lib.cm
1617 :     $smlnj/smlnj-lib/html-lib.cm
1618 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1619 :    
1620 :     This makes it possible to work with code that requires different
1621 :     versions of these libraries, and which refers to these libraries using
1622 :     their "default" names (i.e., the first set of names above). In other
1623 :     words, one can un-define or re-define those default names without
1624 :     compromising the proper functioning of the compiler itself.
1625 :    
1626 :     A similar procedure had already been performed for several of the
1627 :     MLRISC libraries that are linked into the compiler. I did some
1628 :     cleanup on this code.
1629 :    
1630 :     A new file in the config directory (named extrapathconfig) is
1631 :     responsible for setting up path anchors that the compiler itself does
1632 :     not need, but that are typically required by user code.

1811 :     Tag: blume-20050516-redump-heap
1812 :     Description:
1813 :    
1814 :     Added mechanism for re-creating a heap file for the interactive system
1815 :     after configuration variables have been changed.
1816 :    
1817 :     CM.redump_heap : string -> unit
1818 :    
1819 :     This is much like SMLofNJ.exportML, but starting from the resulting
1820 : blume 2155 heap does not return to the caller of CM.redump_heap but
1821 : mblume 1792 restarts the interactive system from scratch. The original call of
1822 :     CM.redump_heap does not return but ends the interactive session.
1823 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1824 :    
1825 :     Internally, redump_heap winds the dynamic execution context back to
1826 :     the point where the original heap image was created and re-executes
1827 :     the heap image generation code in the boot code.

1943 :     Tag: blume-20050114-heap2exec
1944 :     Description:
1945 :    
1946 :     Implemented new (but still experimental) heap2exec facility. This is
1947 :     tested under Mac OS X and should work under Linux (will test shortly).
1948 :     It will probably also work on the Sparc (will test some time later).
1949 :    
1950 :     - removed old "HACKED_STANDALONE" hack from runtime
1951 :    
1952 :     To be able to test this, uncomment the request for "heap2asm" in
1953 :     config/targets prior to installation. (Notice that this is different
1954 :     from "heap2exec" mentioned below. Not a typo.)
1955 :    
1956 :     To perform an actual test, run the command
1957 :    
1958 :     $ bin/heap2exec heapfile execfile
1959 :    
1960 :     (You can put heap2exec on your shell's path.)
1961 :    
1962 :     For example, run
1963 :    
1964 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
1965 :    
1966 :     This will create a standalone executable called "mly" which you can
1967 :     then invoke directly as a command.

1992 :     (The parameter-passing part of the picture has not complete. But
1993 :     data structure access seems to work.)
1994 :    
1995 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
1996 :     (On the Mac, it is big-endian. And that's currently our only
1997 :     PPC platform.)

2014 :    
2015 : blume 2155 The Unix I/O library of SML/NJ on cygwin does not understand

2112 :     Tag: blume-20041124-position
2113 :     Description:
2114 :    
2115 :     The compiler can now be compiled in a mode that makes structure Position
2116 :     equal to Int64. The default, however, is unchanged (Position = Int31)
2117 :     for the time being.
2118 :    
2119 :     To enable 64-bit positions, use the following procedure:
2120 :    
2121 :     1. Start sml
2122 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
2123 :     3. Type
2124 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
2125 :     4. Run CMB.make() as usual.
2126 :    
2127 :     This is barely tested. The only test so far was a little SML program
2128 :     counting the number of characters in an 8-gigabyte file by
2129 :     reading it character-by-character. That test was successful.
2130 :    
2131 :     In support of 64-bit positions, a number of new functions have been
2132 :     added to the runtime system.

2174 :    
2175 :     - Stripped down the versiontool: It now only handles the version number.
2176 :     The date string is generated at bootstrap time (during makeml).
2177 :    
2178 :     - In a previous commit, fixed a minor issue with how polyequal is being
2179 :     translated. In particular, the code now "looks through" abstractions.
2180 :     This results in slightly fewer polyEqual warnings and hopefully slightly
2181 :     more efficient code. Important examples for where this matters are
2182 :     the new int64 and word64 types.

2197 :     Description:
2198 :    
2199 :     All the pieces of Word64 are now there, with the exception of the
2200 :     conversions from and to LargeWord. (Eventually these need to be identities,
2201 :     but for the time being they don't even make sense because LargeWord is
2202 :     32-bit wide.)
2203 :    
2204 :     Also started to add similar support for Int64, but major pieces of that
2205 :     are still missing.

2211 :     Description:
2212 :    
2213 :     Structure Word64 is now (almost) complete, word literals and patterns
2214 :     seem to work. There are a few odd pieces missing. In particular,
2215 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2216 :     at the moment.
2217 :    
2218 :     Making Word64 official would mean that LargeWord becomes Word64. But
2219 :     this requires extreme care because most word-word conversions have to
2220 :     go through LargeWord, so making a mistake means loss of efficiency or
2221 :     worse. Eventually there will be a solution similar to (but actually
2222 :     simpler than) what I did with IntInf.

2258 :     - Default contents of config/srcarchiveurl uses $VERSION and
2259 :     normally does not have to be edited to reflect a version change.
2260 :    
2261 :     (As a result, a version change can be done by just editing
2262 :     config/version, the rest is now automatic.)

2302 :     Tag: blume-20041020-standalone-backtrace
2303 :     Description:
2304 :    
2305 :     Added a mechanism for getting back-trace information from standalone
2306 :     programs. Here is how it works:
2307 :    
2308 :     1. The part of the program from which you want to get backtrace
2309 :     information (usually the whole program) should be wrapped with
2310 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
2311 :     main program could be modified from something like
2312 :    
2313 :     fun main (pgm, args) = ...
2314 :    
2315 :     to
2316 :    
2317 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2318 :    
2319 :     2. To be able to access BackTrace.monitor, you have to add
2320 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
2321 :     main function.
2322 :    
2323 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2324 :     CM might have created in the past for your project).
2325 :    
2326 :     4. Build the system using this command line:
2327 :    
2328 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2329 :     myprog.cm MyProg.main myprog
2330 :    
2331 :     instead of the usual
2332 :    
2333 :     ml-build myprog.cm MyProg.main myprog
2334 :    
2335 :     I changed a library name:
2336 :    
2337 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2338 :    
2339 :     New libraries:
2340 :    
2341 :     $smlnj-tdp/back-trace.cm
2342 :     -- when loaded causes the back-trace plugin to be installed
2343 :     $smlnj-tdp/coverage.cm
2344 :     -- when loaded causes the coverage plugin to be installed

2360 :     Description:
2361 :    
2362 :     * Test coverage tool added!
2363 :     * Further reorganization of tracing-, debugging-, and profiling support:
2364 :    
2365 :     - moved original BTImp -- now called BackTrace -- into a separate
2366 :     library called $/trace-debug-profile.cm
2367 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2368 :     - only the instrumentation mechanism is now left in the compiler proper
2369 :     - BackTrace module is a plugin which is NOT plugged in by default
2370 :     - Coverage module is another such plugin
2371 :    
2372 :     To get the benefits of any of these plugin modules, the code in
2373 :     question must be compiled with tdp instrumentation turned on. This
2374 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2375 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2376 :    
2377 :     Plugins are selected at link time. (Pre-compiled instrumented code
2378 :     can be re-loaded with different plugins in effect.) When an
2379 :     instrumented module is linked, whatever plugins are at that time
2380 :     enabled will come into effect for that module.
2381 :    
2382 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2383 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2384 :     To enable the coverage plugin, load the same library and invoke
2385 :     Coverage.install().
2386 :    
2387 :     Back-traces are generated automatically on uncaught exceptions and
2388 :     when the code in question explicitly invokes BackTrace.trigger().
2389 :    
2390 :     Coverage (and execution frequency-) information must be queried
2391 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2515 :     The first is expected to contain a two-part version number such as 110.49.
2516 :     The second should contain a single number, but it may be missing.
2517 :    
2518 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2519 :     time the version tool is loaded (which is the first time you say CMB.make),
2520 :     then the tool will increment the value stored in config/release every
2521 :     time CMB.make is invoked.
2522 :    
2523 :     The binfile format is now insensitive to anything beyond the first
2524 :     two components of a version number, so bumping the release does not render
2525 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2526 :     during development without invalidating existing binfiles.
2527 :    
2528 :     In any case, every CMB.make updates the date information in version.sml.
2529 :     (This is the date that is printed in the banner.)

2541 : mblume 1633 Date: 2004/09/27 22:08:00 CDT
2542 :     Tag: blume-20040927-controls
2543 :     Description:
2544 :    
2545 :     Added two pieces of functionality to the Controls interface:
2546 :    
2547 :     1. val save'restore: 'a control -> unit -> unit
2548 :    
2549 :     grabs the current value of the control in stage 1 and restores it
2550 :     in stage 2.
2551 :    
2552 :     2. val set' : 'a control * 'a -> unit -> unit
2553 :    
2554 :     stores the given value into the control in stage 2 (i.e., delayed)
2555 :     but does all error checking in stage 1.
2556 :     (This is for string controls that need to do parse their argument --
2557 :     something that might fail. In some cases, notably in CM, one
2558 :     already knows the intended argument but wants to delay the actual
2559 :     assignment until a time when error recovery would be more difficult.)
2560 :    
2561 :     Changed the handling of controls in tool arguments to classes "sml" and
2562 :     "lazysml":
2563 :     - use Controls.save'restore as a more robust way of restoring the
2564 :     old value (in particular: without having to re-parse the string)
2565 :     - use controls to handle the "overload" keyword in the init group
2566 :     (I believe this change actually fixes a long-standing obscure bug.)

2571 :     Tag: blume-20040927-lazysml
2572 :     Description:
2573 :    
2574 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2575 :     difference to "sml" is that compilation is done with Control.lazysml
2576 :     set to true. A source of class "lazysml" is automatically recognized
2577 :     by a file name suffix of ".lml".
2578 :    
2579 :     In addition to the above feature, the original class "sml" now also
2580 :     supports a tool argument "lazy" which has the same effect. As a
2581 :     result, the following three lines are equivalent:
2582 :    
2583 :     foo.sml : lazysml
2584 :     foo.sml : sml (lazy)
2585 :     foo.sml (lazy)
2586 :    
2587 :     The setting goes into effect both during parsing and during
2588 :     compilation. The original setting is restored right after parsing and
2589 :     after compilation, respectively.
2590 :    
2591 :     In addition to all the above, there is also a general mechanism to set
2592 :     ANY of the "controls" that are available at the command line via
2593 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2594 :     apply as well. (In fact, "lazy" is implemented as a special case of
2595 :     the general mechanism.)
2596 :    
2597 :     The .cm file syntax uses a new keyword tool argument called "with".
2598 :     There are several ways of indicating the desired settings:
2599 :    
2600 :     foo.sml (with:parser.quotations=true)
2601 :     foo.sml (with:(name:parser.quotations value:true))
2602 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2603 :     foo.sml (with:(name1=value1 name2=value2 ...))
2604 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2605 :    
2606 :     etc.
2607 :    
2608 :     Another possible abbreviation is to leave out the =v or value:v part
2609 :     if the name refers to a boolean control (in which case the value is
2610 :     taken to be true). Thus, one could get lazy sml also by saying:
2611 :    
2612 :     foo.sml (with:parser.lazy-keyword=true)
2613 :     foo.sml (with:parser.lazy-keyword)
2614 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2615 :     foo.sml (with:(name:parser.lazy-keyword))

2912 :     Description:
2913 :    
2914 :     - use paramAlloc to report c-calls with too many arguments
2915 :     (for PPC version where parameter area is pre-allocated)
2916 :     - added ccall_maxargspace to machspec (to implement the above)
2917 :     - made "make" commend in CM's "make" tool configurable
2918 :     - added option (default: on) for passing the name of the SML/NJ's "bin"
2919 :     directory to "make"; the call looks like this:
2920 :    
2921 :     make <options> SMLNJ_BINDIR=<dir> <target>
2922 :    
2923 :     This can be used by the Makefile to, e.g., pick the "right" version
2924 :     of ml-nlffigen.
2925 :     - minor code tweaks

2931 :     Description:
2932 :    
2933 :     NLFFI under Mac OS X now working (sort of). This is largely untested,
2934 :     though.
2935 :    
2936 :     Note: 1. You have to make a new, clean build of the runtime system.
2937 :     2. There are new BOOTFILES, you have to use them!
2938 :     (Doing the bootstrap process yourself would be *very* painful!
2939 :     If you absolutely have to do it, build the system under
2940 :     a different architecture and then cross-compile.)
2941 :    
2942 :     Version bumped to 110.46.1 to account for runtime data format changes.

2948 :     Description:
2949 :    
2950 :     Changed the implementation of structure Unix so that the same stream
2951 :     is returned every time one of the {text,bin}{In,Out}streamOf functions

2966 :     Tag: blume-20040617-timer-unix
2967 :     Description:
2968 :    
2969 :     Changed the interface of structures Timer and Unix to match the most
2970 :     recent Basis spec.
2971 :    
2972 :     In the case of Unix there still seems to be an open/weird issue:
2973 :    
2974 :     The {text,bin}{In,Out}streamOf functions are supposed to create
2975 :     fresh streams whenever they are called -- as opposed to have them
2976 :     return the same stream every time. This design is supposed to
2977 :     prevent space leaks caused by proc values hanging on to streams.
2978 :    
2979 :     The reap function, on the other hand, is supposed to close the
2980 :     streams. This cannot be done without having a handle on the
2981 :     stream in proc after all...
2982 :    
2983 :     I took the liberty to implement the following stopgap solution:
2984 :    
2985 :     The proc value hangs on to the most recently created stream(s).
2986 :     Reap closes those. If either or both of the two streams hadn't
2987 :     been created at all yet, then reap will close the corresponding
2988 :     file descriptors directly.
2989 :    
2990 :     PS: I don't understand the original space leak argument anymore. If
2991 :     a proc hangs on to the imperative stream, then I/O operations on those
2992 :     will advance the state of the cached stream and avoid the space leak.

3005 :     Tag: blume-20040525-group-owner
3006 :     Description:
3007 :    
3008 :     CM now ignores (but still accepts) the "owner" information in group
3009 :     descriptions. The owner of a group is its next enclosing
3010 :     library. Each group must have a unique owner. (There is a virtual
3011 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
3012 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
3013 :     and CM would check that such a declaration is correct. The new scheme
3014 :     is to have CM check that for each group there is precisely one owning
3015 :     library.
3016 :    
3017 :     The advantage of the new scheme is that the programmer no longer needs
3018 :     to maintain the somewhat annoying owner information. The downside is
3019 :     that CM cannot enforce the ownership rule across multiple runs of
3020 :     CM.make. Fortunately, enclosing the same group in two different
3021 :     libraries A and B which are not part of the same program does not
3022 :     cause real problems.

3032 :     compiled correctly.)
3033 :    
3034 :     Also, included a minor addition to ml-build.bat analogous to what was
3035 :     done in blume-20040519-ml-build.

3041 :     Description:
3042 :    
3043 :     Arranged for ml-build to clean up after itself a little bit better.
3044 :     The script generates a temporary SML source file and compiles it using
3045 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
3046 :     gets rid of those at the end, so they don't accumulate under .cm.
3047 :    
3048 :     This required a minor change to install.sh because the name of the
3049 :     metadata directory (default: .cm) is actually configurable at
3050 :     installation time.

3065 :     Description:
3066 :    
3067 :     Added previously missing support for many socket-related functions
3068 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
3069 :     for the voluminous patch!
3070 :    
3071 :     (I have not tested this patch under win32 yet.)
3072 :    
3073 : mblume 1490 Here is David's e-mail:
3074 :    
3075 :     Hi,
3076 :    
3077 :     Attached to this email you find a diff against sml/nj 110.45
3078 :     that will enable socket support under Windows.
3079 :    
3080 :     To apply the patch (using unix or cygwin)
3081 :     1) gunzip runtime.diff.gz
3082 :     2) "cd" into "src/runtime" in the source tree of a fresh
3083 :     110.45 installation.
3084 :     3) patch -p 1 < [your/path/to]runtime.diff
3085 :    
3086 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
3087 :     I only ran a few tests for basic socket client functionality
3088 :     (which worked fine). Especially the functions that use ioctl
3089 : mblume 1490 are not tested at all and might not work (see below).
3090 :    
3091 :     I implemented this since we want to move to a newer version of sml/nj
3092 :     but need socket support in order to use it. This is the first time I
3093 :     even had a look at the sml/nj source, so please review my changes
3094 :     before making this part of the distribution! Here are a few issues
3095 : blume 2155 that I think might be better for someone to solve who is more
3096 : mblume 1490 familiar with the sml/nj source (and socket programming):
3097 :    
3098 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
3099 :     exception since I could not figure out what the windows equivalent
3100 :     of these functions is
3101 :    
3102 :     - In sockets-osdep.h there are a some #include statements that are
3103 :     only used in a few files that include sockets-osdep.h
3104 :    
3105 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
3106 :     does not process its return value since I don't know how to
3107 :     report an error upwards.
3108 :    
3109 :     - It would probably be good to have a call to WSACleanup() when
3110 : blume 2155 the library is unloaded (if there is such a possibility).
3111 : mblume 1490 Otherwise I think Windows will take care of this automatically
3112 :     when the process finishes.
3113 :    
3114 :     - I used ioctlsocket() as a replacement for ioctl() but I have
3115 :     no idea if that is actually the proper replacement on Windows.
3116 :    
3117 :     - All these issues are marked in the code by "FIXME" comments.
3118 :    
3119 : blume 2155 We use sml/nj extensively in our products and are quite happy
3120 :     with it. I hope this contribution will help you.
3121 : mblume 1490
3122 :     Keep up the good work!

3345 :     Description:
3346 :    
3347 :     I modified the read-eval-print loop so that the autoloader gets
3348 :     invoked whenever the prettyprinter tries to look up a symbol that
3349 :     is not currently defined in the toplevel environment but which
3350 :     appears in CM's autoload registry. As a result, we see far fewer of
3351 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3352 :    
3353 :     In addition to this I tried to clean up some pieces of the Basis
3354 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3355 :     instances of these ?.Foo.Bar.xxx names from being printed.
3356 :    
3357 :     The mechanism that picks names for types still needs some work, though.
3358 :     (Right now it seems that if there is a type A.t which is defined to
3359 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3360 :     "?.B.u" although the perhaps more sensible solution would be to use
3361 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3362 :     a chain of DEFtycs not farther than there are corresponding toplevel
3363 :     names in the current environment.)

3369 :     Description:
3370 :    
3371 :     Another installer tweak: All the ML code for the installer is now
3372 :     compiled during CMB.make and put into a little library called
3373 :     $smlnj/installer.cm. The installation then simply invokes
3374 :    
3375 :     sml -m $smlnj/installer.cm
3376 :    
3377 :     and everything happens automagically.
3378 :    
3379 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3380 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3381 :     and BINDIR.
3382 :    
3383 :     The new scheme guarantees that the ML code responsible for the installation
3384 :     is in sync with the APIs of the main system. Also, the installer is
3385 :     somewhat faster because the installer script is precompiled.

3402 :     Tag: blume-20030924-sockets
3403 :     Description:
3404 :    
3405 :     1. Fixed SOCKET API and implementation to match Basis spec.
3406 :     This required changing the internal representation of sockets to one
3407 :     that remembers (for each socket file descriptor) whether it is currently
3408 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3409 :     call is made only if the state actually needs to change).
3410 :    
3411 :     2. OS-specific details of sockets were moved into separate files, thus
3412 :     making it possible to unify the bulk of the socket implementations
3413 :     between Unix and Win32.
3414 :    
3415 :     3. CML's socket API changed accordingly.
3416 :     (Note that we need to remove non-blocking functions from this API
3417 :     since they are redundant in the case of CML!)
3418 :    
3419 :     4. CML's socket implementation now makes use of non-blocking functions
3420 :     provided by Basis, thus removing all OS-dependent code from this part
3421 :     of CML.
3422 :    
3423 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3536 :     Description:
3537 :    
3538 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3539 :     Modified config/install.bat to take advantage of it. Also modified
3540 :     config/install.sh (and called it config/new-install.sh) to take advantage
3541 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3542 :     independent.)
3543 :    
3544 :     The installer can now install everything under Win32
3545 :     as well as under *nix as long as it compiles.
3546 :    
3547 :     Other changes:
3548 :    
3549 :     - made CML compile again under Win32
3550 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3551 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3552 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3553 :     same as type int; under Win32 it isn't
3554 :     - fixed some slice-related problems in the win32-specific parts of CML
3555 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3556 :     (under Win32, the volume name is case-insensitive, and the
3557 :     OS.Path code compares volume names for equality)

3574 : mblume 1350 Description:
3575 :    
3576 :     1. Changed interface to vectors and arrays in Basis to match
3577 :     (draft) Basis spec.
3578 :     2. Added signatures and implementations of slices according to
3579 :     Basis spec.
3580 :     3. Edited source code throughout the system to make it compile again
3581 :     under 1. and 2. (In some cases code had to be added to have it
3582 :     match the new signatures.)
3583 :     4. MLRISC should be backward-compatible: the copies of the originals
3584 :     of files that needed to change under 3. were retained, the .cm files
3585 :     check the compiler version number and use old versions when
3586 :     appropriate.
3587 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3588 :     dirstream -> string option (in accordance with Basis spec).
3589 :     6. When generating code that counts lines, ml-lex used function
3590 :     CharVector.foldli, taking advantage of its old interface.
3591 :     This has been replaced with the corresponding code from
3592 :     CharVectorSlice. (html-lex must be re-lexed!)
3593 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3594 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3595 :     8. Removed temporary additions (fromInternal, toInternal) from the
3596 :     (now obsolete) IntInf in smlnj-lib/Util.
3597 :     9. Cleaned up structure Byte.
3598 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3599 :     Cleaned/corrected implementation of Date.
3600 :     (Still need to check for correctness; implement better canonicalizeDate.)
3601 :     11. Added "scan" to signature IEEE_REAL.
3602 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3603 :     mod and rem when second operand is 2 (for parity checks).]
3604 :     13. Changed representation of type Time.time, using a single IntInf.int
3605 :     value counting microseconds. This considerably simplified the
3606 :     implementation of structure Time. We now support negative time
3607 :     values; scan and fromString handle signs.
3608 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3609 :     ArraySlice).

3615 :     Description:
3616 :    
3617 :     This is a major update which comes with a version number bump
3618 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3619 :     and an implementation of IntInf in the Basis.
3620 :    
3621 :     There are a fairly large number of related changes and updates throughout
3622 :     the system:
3623 :    
3624 :     Basis:
3625 :     - Implemented IntInf.
3626 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3627 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3628 : mblume 1347 - Added FixedInt as a synonym for Int32.
3629 :    
3630 :     compiler:
3631 :     * Added support for a built-in intinf type.
3632 :     - literals
3633 :     - pattern matching
3634 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3635 :     - overloading on literals and operations
3636 :    
3637 :     This required adding a primitive type intinf, some additional
3638 :     primops, and implementations for several non-trivial intinf
3639 :     operations in Core. (The intinf type is completely abstract
3640 :     to the compiler; all operations get delegated back to the Core.)
3641 :    
3642 :     * Intinf equality is handled by polyequal. However, the compiler
3643 :     does not print its usual warning in this case (since polyequal
3644 :     is the right thing to do there).
3645 :    
3646 :     * Improved the organization of structure InlineT.
3647 :    
3648 :     * A word about conversion primops:
3649 :     If conversions involving intinf do not cancel out during
3650 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3651 : mblume 1347 Since all core access must be resolved already during the FLINT
3652 :     translate phase, it would be too late a the time of CPS contract
3653 : mblume 1348 to add new Core calls. For this reason, conversion primops
3654 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3655 :     they are supposed to convert, and 2. the Core function that
3656 :     can help with this conversion if necessary. If CPS contract
3657 : mblume 1348 eliminates a primop, then the associated Core function becomes
3658 :     dead and goes away. Intinf conversion primops that do not get
3659 :     eliminated by CPS contract get rewritten into calls of their
3660 :     core functions by a separate, new phase.
3661 : mblume 1347
3662 :     interactive system:
3663 :     - Control.Print.intinfDepth controls max length of intinf constants
3664 :     being printed. (Analogous to Control.Print.stringDepth.)
3665 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3666 :     duplicates; replaced some of the code with code that makes better
3667 :     use of library functionality.
3668 :    
3669 :     CM:
3670 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3671 :     are no longer silent.
3672 :    
3673 :     CKIT:
3674 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3675 :     in favor of LargeInt -- which is now the same as IntInf.
3676 :     CKIT-knowledgable people should check whether this is what's
3677 :     intended and otherwise change things back to using Int32 or
3678 :     FixedInt.
3679 :    
3680 :     Throughout the code:
3681 : mblume 1348 Started using IntInf.int literals and built-in operations
3682 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

3693 :     interface with direct use of the SML/NJ Lib PP library, and fixing
3694 :     of a couple of bugs (895, 1186) relating to error messages. A new
3695 :     prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
3696 :     has been added.

3701 :     Tag: blume-20030811-windows
3702 :     Description:
3703 :    
3704 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
3705 :    
3706 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
3707 :    
3708 :     This patch restores SML/NJ's ability to run under win32. There are a
3709 :     number of changes, including fixes for several bugs that had gone
3710 :     unnoticed until now:
3711 :    
3712 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
3713 :     trying to run the win32 version from within cygwin.)
3714 :    
3715 :     - There are a number of simple .bat scripts that substitute for their
3716 :     corresponding Unix shell-scripts. (See below.)
3717 :    
3718 :     - The internals of ml-build have been modified slightly. The main
3719 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
3720 :     using OS.Process.system, the ML process delegates this task back
3721 :     to the script. Otherwise problems arise in mixed environments such
3722 :     as Cygwin where scripts look and work like Unix scripts, but
3723 :     where OS.Process.system cannot run them.
3724 :    
3725 :     - In CM, the srcpath pickler used native pathname syntax -- which
3726 :     is incorrect in the case of cross-compilation. The new pickle format
3727 :     is independent of platform-specific naming conventions.
3728 :    
3729 :     - Path configuration files (such as lib/pathconfig) can now choose
3730 :     between native and standard syntax. Placing a line of the form
3731 :    
3732 :     standard!
3733 :    
3734 :     into the file causes all subsequent paths to be interpreted using
3735 :     CM standard pathname syntax (= Unix conventions); a line
3736 :    
3737 :     native!
3738 :    
3739 :     switches back to native style. This was needed so that
3740 :     path config files can be written portably, see src/system/pathconfig.
3741 :    
3742 :     - Runtime system:
3743 :    
3744 :     - win32-filesys.c: get_file_time and set_file_time now
3745 :     access modification time, not creation time.
3746 :    
3747 :     - I/O code made aware of new array representation.
3748 :    
3749 :     - Bug fixes in X86.prim.masm.
3750 :    
3751 :     - src/system/makeml made aware of win32. (For use under cygwin
3752 :     and other Unix-environments for windows.)
3753 :    
3754 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
3755 :     which caused BinIO.inputAll to fail consistently.
3756 :    
3757 :     .bat scripts:
3758 :    
3759 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
3760 :    
3761 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
3762 :     applications (sml, ml-yacc, ml-lex).
3763 :     - ml-build.bat: analogous to ml-build.
3764 :     - config\install.bat: Analogous to config/install.sh. This requires
3765 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
3766 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
3767 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
3768 :     and the bootfile hierarchy must have been unpacked under
3769 :     sml.boot.x86-win32.
3770 :     The script is very primitive and does a poor job at error checking.
3771 :     It only installs the base system, ml-lex, and ml-yacc. No other
3772 :     libraries are being installed (i.e., you get only those that
3773 :     are part of the compiler.)
3774 :     - link-sml.bat: analogous to .link-sml, but not currently used
3775 :    
3776 :     Unrelated bug fixes:
3777 :    
3778 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
3779 :     types.
3780 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
3781 :     otherwise.)

3805 :     Description:
3806 :    
3807 :     Two changes:
3808 :    
3809 :     1. Added a flag for controlling whether non-exhaustive bindings will
3810 :     be treated as errors (default is false).
3811 :     2. Cleaned up the *entire* source tree so that CMB.make goes through
3812 :     without a single non-exhaustive match- or bind warning.

3817 :     Tag: blume-20030517-absyn
3818 :     Description:
3819 :    
3820 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
3821 :    
3822 :     This mainly affects the quality of error messages. However, some
3823 :     of the code is now more straightforward than before. (Treatment of
3824 :     the above four constructs in translate.sml is much simpler than
3825 :     the "macro-expansion" that was going on before. Plus, the mach-
3826 :     compiler no longer gets invoked just to be able to compile an
3827 :     if-expression.)
3828 :    
3829 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
3830 :     interactive loop.

3836 :     Description:
3837 :    
3838 : blume 2155 Ported the runtime system to cygwin, which uses the unix
3839 : allenleung 1327 x86-unix bin files. Missing/buggy features:
3840 :    
3841 : blume 2155 o getnetbyname, getnetbyaddr: these functions seem to be missing in
3842 : allenleung 1327 the Cygwin library.
3843 :     o Ctrl-C handling may be flaky.
3844 :     o Windows system calls and Windows I/O are not supported.
3845 :    
3846 :     A new set of binfiles is located at:
3847 :    
3848 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
3849 :    
3850 :     This is only needed for bootstrapping the cygwin version of smlnj.
3851 :     Other x86 versions can use the existing binfiles.

3876 :     Description:
3877 :    
3878 :     Fixed a serious bug in the rewrite code for FP spilling/reloading that
3879 :     sent the RA into an infinite loop when floating point registers get
3880 :     spilled. (Because of this bug, e.g., nucleic stopped compiling between
3881 :     110.37 and 110.38.)
3882 :     There was another set of potential problems related to the handling of
3883 :     MLRISC annotations (but those did not yet cause real problems, apparently).

3889 :     Description:
3890 :    
3891 :     Added a call of SrcPath.sync at the beginning of Parse.parse (in CM).
3892 :     This fixes the problem of CM getting confused by files that suddenly
3893 :     change their identity (e.g., by getting unlinked and recreated by some
3894 :     text editor such as vi). There might be a better/cheaper/cleaner way
3895 :     of doing this, but for now this will have to do.

3910 :    
3911 : blume 1282 In good old tradition, there has been a slight hiccup so that we have
3912 :     to patch 110.42 after the fact. The old release tag has been replaced
3913 :     (see below).
3914 :    
3915 :     The change solves a problem with two competing approaches the

3917 :     each other's way.
3918 :

3944 :     Description:
3945 :

3950 :     the entire tree to some other place and everything will "just work".
3951 :

4007 :     Another small change is that ppDec tries to give more information
4008 :     than just "<sig>" in the case of functors. However, this code is
4009 :     broken in some mysterious way if the functor's body's signature
4010 :     has not been declared by ascription but gets inferred from the

4110 :     Description:
4111 :    
4112 :     0. John Reppy made several modifications to the SML/NJ library.
4113 :     In particular, there is a shiny new controls-lib.cm.
4114 :    
4115 :     1. Pushed new controls interface through compiler so that everything
4116 :     compiles again.
4117 :    
4118 :     2. Added FormatComb and FORMAT_COMB to the CML version of the
4119 :     SML/NJ library (so that CML compiles again).
4120 :    
4121 :     3. Modified init scripts because XXX_DEFAULT environment variables
4122 :     are no longer with us. (Boot-time initialization is now done
4123 :     using the same environment variables that are also used for
4124 :     startup-time initialization of controls.)

4130 :     Description:
4131 :    
4132 :     All pseudo-ops emitted before the first segment declaration
4133 :     such as TEXT, DATA, and BSS directives are assumed to be global
4134 :     declarations and are emitted first in the assembly file. This is
4135 :     useful in a number of situations where one has pseudo-ops that are not
4136 :     specific to any segment, and also works around the constraint that one
4137 :     cannot have client pseudo-ops in the TEXT segment.
4138 :    
4139 :     Because no segment is associated with these declarations it is
4140 :     an error to allocate any space or objects before the first segment
4141 :     directive and an exception will be raised. However, we cannot make
4142 :     this check for client pseudo-ops.
4143 :    
4144 :     These top level declarations are a field in the CFG graph_info.
4145 :     In theory you can continue to add to this field after the CFG has been
4146 :     built -- provided you know what you are doing;-)

4151 :     Tag: blume-20020513-pp-etc
4152 :     Description:
4153 :    
4154 :     A few minor bugfixes:
4155 :    
4156 :     - Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
4157 :     (Bogus printouts for redefined bindings still occur. Compiler
4158 :     bug should no longer occur now. We need to redo the prettyprinter
4159 :     from scratch.)
4160 :    
4161 :     - CM pathname printer now also adds escape sequences for ( and )
4162 :    
4163 :     - commend and docu fixes for ml-nlffi

4169 :     Description:
4170 :    
4171 :     Applied the following bugfix provided by Emden Gansner:
4172 :    
4173 :     Output is corrupted when outputSubstr is used rather than output.
4174 :    
4175 : blume 2155 The problem occurs when a substring
4176 : blume 1189
4177 :     ss = (s, dataStart, dataLen)
4178 :    
4179 : blume 2155 where dataStart > 0, fills a stream buffer with avail bytes left.
4180 :     avail bytes of s, starting at index dataStart, are copied into the
4181 : blume 1189 buffer, the buffer is flushed, and then the remaining dataLen-avail
4182 : blume 2155 bytes of ss are copied into the beginning of the buffer. Instead of
4183 :     starting this copy at index dataStart+avail in s, the current code
