1 : blume 2237 This is the HISTORY file for the SML/NJ repository.
2 : dbm 570
3 :     An entry should be made for _every_ commit to the repository.
4 :     The entries in this file will be used when creating the README
5 :     for new versions, so keep that in mind when writing the
6 :     description.
7 :    
8 :     The form of an entry should be:
9 :    
10 : mblume 1931 Name: Your Name (web page or e-mail)
11 : blume 2155 Date: yyyy/mm/dd hh:mm:ss

23 : jhr 3821 Name: John Reppy (http://cs.uchicago.edu/~jhr)
24 : jhr 3966 Date: 2014/10/23
25 :     Description:
26 :    
27 :     Improved error messages in ml-ulex for unclosed strings. Also made
28 :     documentation improvements.
29 :    
30 :     ----------------------------------------------------------------------
31 : dbm 3991 Name: David MacQueen (http://cs.uchicago.edu/~dbm)
32 :     Date: 2014/12/13
33 :     Description: preliminary cleanups before changes to overloading
34 :    
35 :     Minor cleanup in Elaborator/elaborate/elabcore (fun elabOVERLOADdec)
36 :     and in ElabData/types/typesutil.sml (fun matchScheme). Preparing for
37 :     new method of handling type checking of overloaded operators. [Note
38 :     that there is no reason for the options field of OVLDvar to be a
39 :     reference -- it is never updated. Changing this requires corresponding
40 :     change in pickling.]
41 :    
42 :     Also added an etopdebugging flag (ElabControl) for debugging in elabtop.sml.
43 :     Modified elabcontrol.s?? and elabtop.sml. Also rearranged ast and absyn
44 :     printing in evalloop.sml.

47 : jhr 3966 Name: John Reppy (http://cs.uchicago.edu/~jhr)
48 : jhr 3964 Date: 2014/10/11
49 :     Description:
50 :    
51 :     Added -D_FILE_OFFSET_BITS=64 flag to x86-linux makefile. This flag
52 :     is necessary to avoid spurious EOVERFLOW errors on some versions of
53 : jhr 3965 Linux. The problem appears to be limited to large file systems that
54 :     have more than 2^32 inodes.

59 :     Description:
60 :    
61 : jhr 3970 Added %value directive to ml-antlr; this addition improves the
62 : jhr 3961 error repair choices by allowing non-nullary tokens to be inserted
63 :     when making repairs.

74 : jhr 3912 Date: 2014/08/19
75 :     Description:
76 : jhr 3914 Compiling the runtime system on cygwin was failing because the file
77 :     exceptions.h was missing. It appears to have been part of previous
78 :     versions, so a version has been incorporated verbatim in the
79 :     runtime/mach-base/cygwin-fault.c file (fixes bug #125).

84 :     Description:
85 : jhr 3912 Added the actionToString' and repairToString' functions
86 :     to the AntlrRepair structure. These functions allow one to
87 :     specialize the printing of tokens based on whether they are
88 :     being added or deleted.

100 :     Description:
101 : jhr 3903 Use mkstemp to implement OS.FileSys.tmpName() on systems that support
102 :     it (should be all modern versions of Unix). This change fixes bug #128.
103 :     (Thanks to Johannes 5 Joemann).

123 :     Description:
124 :     Switch to using MAP_ANONYMOUS to allocate memory on Linux systems.
125 :     This change avoids problems when "/dev" does not support execute
126 :     permission (as seems to be the case with some versions of Linux
127 :     running on ChromeBooks; bug #120).
128 :

153 :     Description:
154 :     Added PackWord{16,32}{Big,Little} structures to the Unsafe module.
155 :     This change makes the UNSAFE signature closer to the MLton version,

175 :     Date: 2013/06/04
176 :     Description:
177 :     Fix bug #111 (Socket.acceptNB returns somewhat broken sockets).
178 :     The problem was that under Win32, sockets returned from accept inherit
179 :     their parents' non-blocking status, whereas on UNIX they are always
180 :     blocking.

193 :     Description:
194 :     Fix bug #116 (Socket.sameDesc raises Match exception).
195 :     The problem is that on Windows the iodesc datatype (defined in
196 :     Basis/Implementation/Win32/pre-os.sml) has both an IODesc constructor

961 :     - Aaron: fixed a number of bugs in ml-ulex.
962 :     - Matthias:
963 :     - added CM control "cm.force-tools"; this is false by default;

965 :     will be forced to run regardless of whether or not their targets

994 :     Description:
995 :    
996 :     3rd merge of base from primop-branch-3 into the trunk.
997 :     Additional bug fixes included:
998 :    
999 :     * Timer.cpu_timer, etc. type printing corrected (by making

1007 :     Description:
1008 :    
1009 :     Fixed some bugs in new Div code in FLINT/trans/translate.sml.
1010 :    
1011 :     Also, changed the handling of "no core access": When translate.sml
1012 :     needs access to a core exception at a time when the core has not
1013 :     been set up yet (this only happens when compiling system/smlnj/init/*),
1014 :     then don't bother generating the corresponding tests.
1015 :    
1016 : dbm 2650 The old scheme was to generate a bogus value to be used in place of
1017 :     the exception. Unfortunately, that confuses the plambda type checker.
1018 :     Moreover, it does not do any good, because at runtime we don't expect
1019 :     such an exception to be ever raised. (The code in system/smlnj/init/*
1020 :     has to be written very carefully with this in mind!)

1032 :     Description:
1033 :    
1034 :     FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
1035 :     with an explicit test for zero division. This should fixes several
1036 :     regressions and makes it possible for downstream optimization phases

1044 :    
1045 :     Added the new MLRISC code generator for the AMD64. This version,

1053 :    
1054 : jhr 2617 A number of fixes related to the formatting of dates. These include fixes
1055 :     for bugs #1415 and #1416. We also now correctly handle format characters that

1060 :     Date: 2007/05/23 22:30:00 CDT
1061 :     Description:
1062 :    
1063 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
1064 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
1065 :    
1066 :     (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
1067 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
1068 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
1069 :     while running CMB.make. The point is that the single symbol
1070 :     NO_PLUGINS is definde in all three cases.)
1071 :    
1072 :     I changed the three locations within the sources that get compiled
1073 :     during CMB.make where ml-yacc or ml-lex input is processed: When
1074 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
1075 :     is bypassed.
1076 :    
1077 :     When bootstrapping new versions of the compiler, there can be
1078 :     situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
1079 :     are not available or otherwise not operational. In this case one can
1080 :     manually define the NO_PLUGINS symbol prior to running CMB.make(). To
1081 :     do so, the following command should be issued at the interactive
1082 :     prompt:
1083 :    
1084 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
1085 :    
1086 :     A CMB.make with NO_PLUGINS defined relies on the existence of the
1087 :     files that normally would be generated by ml-yacc and ml-lex.
1088 :     (Copies of these files are in the repository.)

1104 :     Description:
1105 :    
1106 :     Changed the installation mechanism for CM tool plugins. These are
1107 :     just libaries and now get installed like ordinary libaries.
1108 :    
1109 :     There are now a number of new installation targets that give some
1110 :     fine-grain control over what classes and suffixes are known, and what
1111 :     they will map to.
1112 :     See config/targets for details.
1113 :    
1114 :     The code that caused plugin installation as part of running a
1115 :     tool's "build" script has been removed. (The build script is for
1116 :     building, not for installing.)

1121 :     Description:
1122 :    
1123 :     Added a boolean control named cm.tolerate-tool-failures (env. variable
1124 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
1125 :     CM fail if a shell tool reports a non-success exit status. If
1126 :     the control is set to true, then CM will press on after tool failures
1127 :     in the event that the target files exist (even though they are
1128 :     considered outdated). Turning the control to true can be useful for
1129 :     bootstrapping.

1134 :     Description:
1135 :    
1136 :     Merge of ml-lpt revisions for 110.64.
1137 :    
1138 :     The name of several ml-lpt-lib modules has changed:
1139 :     Repair => AntlrRepair
1140 :     StreamPos => AntlrStreamPos
1141 :     ErrHandlerFn => AntlrErrHandler
1142 :     EBNF => AntlrEBNF
1143 :    
1144 :     The ml-antlr specification format has changed: declarations such as
1145 :     %tokens and nonterminal definitions can occur *multiple* times in the
1146 :     same specification. The semantics are such that each new declaration
1147 :     extends the previous ones. This does not apply to %start or %name,
1148 :     of course.
1149 :    
1150 :     Importing a grammar via %import now includes *all* declarations in from
1151 :     the imported grammar, except for %name, %entry, and %start. Tokens
1152 :     and nonterminals can be dropped using the new %dropping clause of the
1153 :     %import directive; the separate %drop and %extend have been removed.
1154 :    
1155 :     We now allow optional type annotations on nonterminals, using the %nonterms
1156 :     directive as in ml-yacc.
1157 :    
1158 :     The refcell construct is now implemented using SML's regular reference
1159 :     cells, so the :== and !! notation has been deprecated.
1160 :    
1161 :     The ml-antlr tool now does much more checking of specifications, and
1162 :     its error messages have been greatly improved. Error repair for
1163 :     generated parsers has been completely rewritten, and is now both
1164 :     much faster and more accurate.
1165 :    
1166 :     ml-ulex is now more lenient with escape codes (non-SML-standard
1167 :     escape codes are now interpreted literally, so e.g. \| denotes "|").
1168 :     Also, character classes may now include a "-" character at the beginning
1169 :     as is standard in most other regexp tools.
1170 :    
1171 :     All of these changes are documented in the user guide, which has
1172 :     been updated and improved with this merge.

1178 :     Description:
1179 :    
1180 :     Merge of the primop3 branch (base) into the trunk to create 110.63.1.
1181 :     Significant changes in FLINT and the front end, mostly having to do
1182 :     with a reorganized system for handling primops. Various bug fixes
1183 :     and improvements in printing signatures.

1188 :     Description:
1189 :    
1190 :     Preliminary commit of large ml-lpt revisions (more to come for 110.64).
1191 :     The ml-antlr specification format has changed: declarations such as
1192 :     %tokens and nonterminal definitions can occur *multiple* times in the
1193 :     same specification. The semantics are such that each new declaration
1194 :     extends the previous ones. Grammar extension constructs have also
1195 :     changed. We now allow type annotations on nonterminals. Finally,
1196 :     the refcell construct is now implemented using SML's regular reference
1197 :     cells, so the :== and !! notation has been deprecated. All of these
1198 :     changes will appear in the 110.64 user guide for ml-lpt.
1199 :    
1200 :     The ml-antlr tool now does much more checking of specifications, and
1201 :     its error messages have been greatly improved. There has also been
1202 :     some work on the error repair process for generated parsers, but this
1203 :     will be further improved in 110.64.

1289 :     Date: 2007/02/26
1290 :     Description:
1291 :    
1292 :     Added preliminary support in MLRISC for Staged Allocation, a technique
1293 :     for specifying calling conventions (see
1294 :     http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
1295 :     Initially, we plan to use this code to generate C calls for the AMD64.
1296 :    
1297 :     The staged allocation code base resides in MLRISC/staged-allocation,
1298 :     and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

1304 :    
1305 :     Bug fix: when SaveCState was called with two values to save, a subsequent
1306 :     GC could cause the RestoreCState to fail because the saved state had been
1307 :     promoted to tagless pair.

1318 :    
1319 :     x86MCEmitter crashed when the immediate operand to MOVB was outside
1320 :     of the range -128 ... 127. I've changed the code so that the range
1321 :     check is disabled. Only the low order 8 bits of the immediate operand

1362 :     Date: 2007/01/31
1363 :     Description:
1364 :    
1365 :     Brought ml-lpt manual up-to-date with the code. Many minor
1366 :     improvements to the tools, and a few minor bugfixes. Prepared
1367 :     ml-lpt-lib for integration with new UTF8 structure. Changed
1368 :     the interface for creating streams in ml-ulex (we now support
1369 :     stream creation from several kinds of sources). Overall, the
1370 :     tools are now quite stable, and their interfaces are unlikely to
1371 :     change in a way that would break compatibility. More work,
1372 :     however, is needed in the documentation.

1377 :     Description:
1378 :    
1379 :     Implemented library installer. Moved CM plugin code for
1380 :     ml-burg, ml-lex, and ml-yacc out of CM source tree and into
1381 :     their respective trees. Implemented CM plugin for ml-ulex
1382 :     and ml-antlr. Used library installer for ml-burg, ml-ulex,
1383 :     and ml-antlr.
1384 :    
1385 :     For ml-yacc and ml-lex we continue to have permanently "plugged-in"
1386 :     CM tools. (It turns out to be too messy to do otherwise because
1387 :     there is too much code that during installation relies on the presence
1388 :     of these tools -- resulting in a tricky ordering problem.)

1393 :     Description:
1394 :    
1395 :     Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
1396 :     Modified CM's startup code to use shiftArgs as it processes
1397 :     command line arguments. This way, the init code in each .sml-file
1398 :     or library that is mentioned at the top level will see only
1399 :     those arguments that have not yet been processed at this point.
1400 :     In other words, the init code can "seize control" and process the
1401 :     remaining command line.

1415 :    
1416 :     Added the UTF8 structure and signature from the Moby compiler to

1468 :     Description:
1469 :    
1470 :     Added code to CM's "standard shell tool" implementation which
1471 :     causes it to tolerate (with a warning) the situation where the shell
1472 :     command fails (e.g., due to the shell command's non-existence)
1473 :     as long as all target files exist.
1474 :    
1475 :     This makes it possible to, e.g., build ml-yacc from sources even if
1476 :     svn checkout messed up the time stamps on files in such a way that
1477 :     yacc.grm is younger than yacc.grm.sml or yacc.grm.sig. (Ml-yacc would
1478 :     be needed to re-process yacc.grm, but obviously it might not yet be
1479 :     available at that time.)

1486 :     Fixed the types of recvVecFrom, recvVecFrom', recvVecFromNB, and
1487 :     recvVecFromNB' in the SOCKET signature. This error is actually
1488 :     in the SML Basis specification too.

1518 :     Tag: release-110.60
1519 :     Description:
1520 :    
1521 :     New working release (110.60). NEW BOOTFILES!
1522 :    
1523 :     This is the first subversion-hosted release. There are also changes
1524 :     to the directory layout. Here is a table:
1525 :    
1526 :     (All pathnames are relative to the SML/NJ "root" directory.)
1527 :    
1528 :     config -> config
1529 :    
1530 :     src/cm -> base/cm
1531 :     src/compiler -> base/compiler
1532 :     src/runtime -> base/runtime
1533 :     src/system -> base/system
1534 :    
1535 :     src/cm/pgraph -> pgraph
1536 :    
1537 :     src/READMES -> base/READMES
1538 :     src/$notefile -> base/NOTES/$notefile
1539 :     for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1540 :     MACOSXINSTALL WININSTALL
1541 :    
1542 :     src/smlnj-lib -> smlnj-lib
1543 :     src/MLRISC -> MLRISC
1544 :     ckit -> ckit
1545 :     src/cml -> cml
1546 :     src/eXene -> eXene
1547 :     src/heap2asm -> heap2asm
1548 :     src/lexgen -> lexgen
1549 :     src/ml-burg -> ml-burg
1550 :     src/ml-lex -> ml-lex
1551 :     src/ml-yacc -> ml-yacc
1552 :     src/ml-nlffi-lib -> nlffi/lib
1553 :     src/ml-nlffigen -> nlffi/gen
1554 :     src/smlnj-c -> smlnj-c
1555 :     src/tools/TraceDebugProf -> trace-debug-profile
1556 :    
1557 :     In addition, there is also a new
1558 :    
1559 :     ml-lpt
1560 :    
1561 :     directory containing two new program generator tools: ml-ulex and
1562 :     ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1563 :     LL(k) parser generator). These tools are currently "beta-quality"
1564 :    
1565 :     The latest versios of the sources can now be obtained anonymously
1566 :     via subversion. For this, it is useful to first check out
1567 :    
1568 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1569 :    
1570 :     and put the resulting directory on your shell's PATH. This provides
1571 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
1572 :     and refresh-all.sh.
1573 :    
1574 :     To create a freshly checked-out copy of the sources, do
1575 :    
1576 :     checkout-all.sh [dir]
1577 :    
1578 :     where dir is the optional SML/NJ root directory (default is ".").
1579 :    
1580 :     This creates the above directory layout. Each subdirectory of
1581 :     the root is under individual subversion control. The stat-all.sh
1582 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
1583 :     each of these subtrees.
1584 :

1586 :     Name: Matthias Blume (http://www.tti-c.org/blume/)
1587 : blume 2155 Date: 2006/11/02 12:20:00 CST
1588 :     Description:
1589 :    
1590 :     Reorganized directory layout.
1591 :    
1592 :     This is a temporary solution, more reorganization is to come.
1593 :    
1594 :     The basic idea is to have a number of toplevel trees, each corresponding
1595 :     to a well-defined part of the overall system. Each part can be
1596 :     maintained individually, even in separate source repositories,
1597 :     although currently we still serve everything out of the main
1598 :     smlnj-gforge tree.
1599 :    
1600 :     Installer and and scripts have been updated to reflect the new
1601 :     layout. The installer (base/src/system/smlnj/installer) is now
1602 :     "scriptable" to avoid burning too much knowledge about the
1603 :     layout into SML source code. The main script used by the installer
1604 :     is in config/actions.
1605 :    
1606 :     The main change is that many of the subdirectories of what used to
1607 :     be known as "src" have moved to the toplevel. The "src" directory
1608 :     itself has moved down into a subtree called "base". (We may eventually
1609 :     get rid of the extra level of indirection represented by "src".)
1610 :    
1611 :     The layout is now as follows:
1612 :    
1613 :     toplevel tree name | default repository
1614 :     | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1615 :     -------------------+----------------------------------------------------
1616 :     config | $gf/config/trunk
1617 :     |
1618 :     base | $gf/sml/trunk
1619 :     |
1620 :     smlnj-lib | $gf/smlnj-lib/trunk
1621 :     MLRISC | $gf/MLRISC/trunk
1622 :     |
1623 :     ml-yacc | $gf/ml-yacc/trunk
1624 :     ml-lex | $gf/ml-lex/trunk
1625 :     ml-burg | $gf/ml-burg/trunk
1626 :     lexgen | $gf/lexgen/trunk
1627 :     heap2asm | $gf/heap2asm/trunk
1628 :     |
1629 :     cml | $gf/cml/trunk
1630 :     eXene | $gf/eXene/trunk
1631 :     ckit | $gf/ckit/trunk
1632 :     nlffi | $gf/nlffi/trunk
1633 :     |
1634 :     smlnj-c | $gf/smlnj-c/trunk
1635 :    
1636 :     In $gf/admin there are a few useful shell scripts for checking out
1637 :     and maintaining the entire collection of trees:
1638 :    
1639 :     admin/checkout-all.sh [dir]
1640 :     -- optionally creates dir and checks out all trees from their
1641 :     default repositories; if dir is missing, checkout into .
1642 :     admin/refresh-all.sh [dir]
1643 :     -- looks at all trees (from the above list) in dir (default: .)
1644 :     and runs "svn update" if the tree exists and is under
1645 :     subversion control;
1646 :     non-existing or non-subversion trees are skipped
1647 :     admin/stat-all.sh [dir]
1648 :     -- like refresh-all.sh, but runs "svn stat" instead

1702 :    
1703 :     Fixed long-standing bug with ml-makedepend where it would output a
1704 :     spurious dependency to a non-existing file. (This is a simple fix.
1705 :     It might need further looking into.)

1794 :     Description:
1795 :    
1796 :     Hooked code for Darwin-specific Intel ABI into main compiler.
1797 :     (This is a temporary solution which relies on the fact that the
1798 :     compiler itself does not use NLFFI. Eventually we need to divorce
1799 :     intel mac from generic x86 unix code and make separate sets of binaries.)

1828 :     Description:
1829 :    
1830 :     Enabling $/html-lib.cm in config/preloads did not work. This is fixed
1831 :     now. (Since the anchor mapping for html-lib.cm is not yet in effect
1832 : blume 2155 at the time when config/preloads is processed, the library has to
1833 : mblume 1878 be referred to by another name. In 110.57 this would be
1834 :     $SMLNJ-LIB/HTML/html-lib.cm. I arranged for $smlnj/smlnj-lib/html-lib.cm
1835 :     to be valid as well.)
1836 :

1890 :     Tag: blume-22051115-versiontool
1891 :     Description:
1892 :    
1893 :     Reversed change to src/system/smlnj/internals/versiontool.cm. This
1894 :     file gets loaded as a tool -- by the equivalent of CM.make during the
1895 :     run of CMB.make. Thus, CMB's path configuration is meaningless for
1896 :     it. Instead, it has the status of "user code", so it should use
1897 :     $/basis.cm to refer to the Basis library. (At least that's true for
1898 :     the purpose of bootstrapping the previous change. In the future it
1899 :     might make sense to have versiontool.cm refer to
1900 :     $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1901 :     compiler itself uses.)
1902 :    
1903 :     Also patched src/system/testml to have it activate those extra anchor
1904 :     bindings in config/extrapathconfig.

1909 :     Tag: blume-22051115-libraries
1910 :     Description:
1911 :    
1912 :     This change affects the way the following libraries are tied into
1913 :     the system:
1914 :    
1915 :     $/basis.cm
1916 :     $/smlnj-lib.cm
1917 :     $/pp-lib.cm
1918 :     $/controls-lib.cm
1919 :     $/html-lib.cm
1920 :     $/ml-yacc-lib.cm
1921 :    
1922 :     These libraries are now internally (as seen from the source code
1923 :     of the implementation itself) known by the following names:
1924 :    
1925 :     $smlnj/basis/basis.cm
1926 :     $smlnj/smlnj-lib/smlnj-lib.cm
1927 :     $smlnj/smlnj-lib/pp-lib.cm
1928 :     $smlnj/smlnj-lib/controls-lib.cm
1929 :     $smlnj/smlnj-lib/html-lib.cm
1930 :     $smlnj/ml-yacc/ml-yacc-lib.cm
1931 :    
1932 :     This makes it possible to work with code that requires different
1933 :     versions of these libraries, and which refers to these libraries using
1934 :     their "default" names (i.e., the first set of names above). In other
1935 :     words, one can un-define or re-define those default names without
1936 :     compromising the proper functioning of the compiler itself.
1937 :    
1938 :     A similar procedure had already been performed for several of the
1939 :     MLRISC libraries that are linked into the compiler. I did some
1940 :     cleanup on this code.
1941 :    
1942 :     A new file in the config directory (named extrapathconfig) is
1943 :     responsible for setting up path anchors that the compiler itself does
1944 :     not need, but that are typically required by user code.

2106 :     Description:
2107 :    
2108 :     Added support scripts for Mac OS X PackageMaker and modified
2109 :     config/install.sh so that it supports re-dumping a heap image
2110 :     after customization.

2123 :     Tag: blume-20050516-redump-heap
2124 :     Description:
2125 :    
2126 :     Added mechanism for re-creating a heap file for the interactive system
2127 :     after configuration variables have been changed.
2128 :    
2129 :     CM.redump_heap : string -> unit
2130 :    
2131 :     This is much like SMLofNJ.exportML, but starting from the resulting
2132 : blume 2155 heap does not return to the caller of CM.redump_heap but
2133 : mblume 1792 restarts the interactive system from scratch. The original call of
2134 :     CM.redump_heap does not return but ends the interactive session.
2135 :     Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
2136 :    
2137 :     Internally, redump_heap winds the dynamic execution context back to
2138 :     the point where the original heap image was created and re-executes
2139 :     the heap image generation code in the boot code.

2145 :     Description:
2146 :    
2147 :     Added a hack to the existing hack known as Word64 to make fromString
2148 :     behave correctly. I am still not sure whether Word64.scan will work
2149 :     as specified with respect to the interaction of radix and prefix.

2199 :     Description:
2200 :    
2201 :     Brought back SMLofNJ.Susp. The underlying suspension type is the one
2202 :     implemented in Core -- which means that it is the same as the one used
2203 :     by the lazy extension.

2229 :     Implemented "long long" arguments and results for NLFFI. (Only the
2230 :     PPC/MacOS implementation is complete, the other backends still need to
2231 :     be updated.)

2255 :     Tag: blume-20050114-heap2exec
2256 :     Description:
2257 :    
2258 :     Implemented new (but still experimental) heap2exec facility. This is
2259 :     tested under Mac OS X and should work under Linux (will test shortly).
2260 :     It will probably also work on the Sparc (will test some time later).
2261 :    
2262 :     - removed old "HACKED_STANDALONE" hack from runtime
2263 :    
2264 :     To be able to test this, uncomment the request for "heap2asm" in
2265 :     config/targets prior to installation. (Notice that this is different
2266 :     from "heap2exec" mentioned below. Not a typo.)
2267 :    
2268 :     To perform an actual test, run the command
2269 :    
2270 :     $ bin/heap2exec heapfile execfile
2271 :    
2272 :     (You can put heap2exec on your shell's path.)
2273 :    
2274 :     For example, run
2275 :    
2276 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
2277 :    
2278 :     This will create a standalone executable called "mly" which you can
2279 :     then invoke directly as a command.

2303 :     * Implemented access to signed and unsigned long long data in NLFFI.
2304 :     (The parameter-passing part of the picture has not complete. But
2305 :     data structure access seems to work.)
2306 :    
2307 :     * Fixed CM's incorrect assumption that the PPC is little-endian.
2308 :     (On the Mac, it is big-endian. And that's currently our only
2309 :     PPC platform.)

2326 :    
2327 : blume 2155 The Unix I/O library of SML/NJ on cygwin does not understand

2424 :     Tag: blume-20041124-position
2425 :     Description:
2426 :    
2427 :     The compiler can now be compiled in a mode that makes structure Position
2428 :     equal to Int64. The default, however, is unchanged (Position = Int31)
2429 :     for the time being.
2430 :    
2431 :     To enable 64-bit positions, use the following procedure:
2432 :    
2433 :     1. Start sml
2434 :     2. Autoload $smlnj/cmb.cm (if not already autoloaded)
2435 :     3. Type
2436 :     #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
2437 :     4. Run CMB.make() as usual.
2438 :    
2439 :     This is barely tested. The only test so far was a little SML program
2440 :     counting the number of characters in an 8-gigabyte file by
2441 :     reading it character-by-character. That test was successful.
2442 :    
2443 :     In support of 64-bit positions, a number of new functions have been
2444 :     added to the runtime system.

2485 :     Description:
2486 :    
2487 :     - Stripped down the versiontool: It now only handles the version number.
2488 :     The date string is generated at bootstrap time (during makeml).
2489 :    
2490 :     - In a previous commit, fixed a minor issue with how polyequal is being
2491 :     translated. In particular, the code now "looks through" abstractions.
2492 :     This results in slightly fewer polyEqual warnings and hopefully slightly
2493 :     more efficient code. Important examples for where this matters are
2494 :     the new int64 and word64 types.

2512 :     conversions from and to LargeWord. (Eventually these need to be identities,
2513 :     but for the time being they don't even make sense because LargeWord is
2514 :     32-bit wide.)

2523 :     Description:
2524 :    
2525 :     Structure Word64 is now (almost) complete, word literals and patterns
2526 :     seem to work. There are a few odd pieces missing. In particular,
2527 :     I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2528 :     at the moment.
2529 :    
2530 :     Making Word64 official would mean that LargeWord becomes Word64. But
2531 :     this requires extreme care because most word-word conversions have to
2532 :     go through LargeWord, so making a mistake means loss of efficiency or
2533 :     worse. Eventually there will be a solution similar to (but actually
2534 :     simpler than) what I did with IntInf.

2571 :     normally does not have to be edited to reflect a version change.
2572 :    
2573 :     (As a result, a version change can be done by just editing

2614 :     Tag: blume-20041020-standalone-backtrace
2615 :     Description:
2616 :    
2617 :     Added a mechanism for getting back-trace information from standalone
2618 :     programs. Here is how it works:
2619 :    
2620 :     1. The part of the program from which you want to get backtrace
2621 :     information (usually the whole program) should be wrapped with
2622 :     BackTrace.monitor. This is a (unit->'a)->'a function, and your
2623 :     main program could be modified from something like
2624 :    
2625 :     fun main (pgm, args) = ...
2626 :    
2627 :     to
2628 :    
2629 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2630 :    
2631 :     2. To be able to access BackTrace.monitor, you have to add
2632 :     library $smlnj-tdp/plugins.cm to the .cm file that contains your
2633 :     main function.
2634 :    
2635 :     3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2636 :     CM might have created in the past for your project).
2637 :    
2638 :     4. Build the system using this command line:
2639 :    
2640 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2641 :     myprog.cm MyProg.main myprog
2642 :    
2643 :     instead of the usual
2644 :    
2645 :     ml-build myprog.cm MyProg.main myprog
2646 :    
2647 :     I changed a library name:
2648 :    
2649 :     $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2650 :    
2651 :     New libraries:
2652 :    
2653 :     $smlnj-tdp/back-trace.cm
2654 :     -- when loaded causes the back-trace plugin to be installed
2655 :     $smlnj-tdp/coverage.cm
2656 :     -- when loaded causes the coverage plugin to be installed

2672 :     Description:
2673 :    
2674 :     * Test coverage tool added!
2675 :     * Further reorganization of tracing-, debugging-, and profiling support:
2676 :    
2677 :     - moved original BTImp -- now called BackTrace -- into a separate
2678 :     library called $/trace-debug-profile.cm
2679 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
2680 :     - only the instrumentation mechanism is now left in the compiler proper
2681 :     - BackTrace module is a plugin which is NOT plugged in by default
2682 :     - Coverage module is another such plugin
2683 :    
2684 :     To get the benefits of any of these plugin modules, the code in
2685 :     question must be compiled with tdp instrumentation turned on. This
2686 :     can be done by setting SMLofNJ.Internals.TDP.mode to true.
2687 :     (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2688 :    
2689 :     Plugins are selected at link time. (Pre-compiled instrumented code
2690 :     can be re-loaded with different plugins in effect.) When an
2691 :     instrumented module is linked, whatever plugins are at that time
2692 :     enabled will come into effect for that module.
2693 :    
2694 :     To enable the back-trace plugin, load library $/trace-debug-profile.cm
2695 :     and invoke BackTrace.install() (e.g., from the interactive prompt).
2696 :     To enable the coverage plugin, load the same library and invoke
2697 :     Coverage.install().
2698 :    
2699 :     Back-traces are generated automatically on uncaught exceptions and
2700 :     when the code in question explicitly invokes BackTrace.trigger().
2701 :    
2702 :     Coverage (and execution frequency-) information must be queried
2703 :     explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2821 :     Description:
2822 :    
2823 :     Implemented some CM magic to have
2824 :     file src/compiler/TopLevel/main/version.sml
2825 :     generated automagically.
2826 :     The version is taken from two files: config/version and config/release.
2827 :     The first is expected to contain a two-part version number such as 110.49.
2828 :     The second should contain a single number, but it may be missing.
2829 :    
2830 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2831 :     time the version tool is loaded (which is the first time you say CMB.make),
2832 :     then the tool will increment the value stored in config/release every
2833 :     time CMB.make is invoked.
2834 :    
2835 :     The binfile format is now insensitive to anything beyond the first
2836 :     two components of a version number, so bumping the release does not render
2837 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
2838 :     during development without invalidating existing binfiles.
2839 :    
2840 :     In any case, every CMB.make updates the date information in version.sml.

2854 :     Tag: blume-20040927-controls
2855 :     Description:
2856 :    
2857 :     Added two pieces of functionality to the Controls interface:
2858 :    
2859 :     1. val save'restore: 'a control -> unit -> unit
2860 :    
2861 :     grabs the current value of the control in stage 1 and restores it
2862 :     in stage 2.
2863 :    
2864 :     2. val set' : 'a control * 'a -> unit -> unit
2865 :    
2866 :     stores the given value into the control in stage 2 (i.e., delayed)
2867 :     but does all error checking in stage 1.
2868 :     (This is for string controls that need to do parse their argument --
2869 :     something that might fail. In some cases, notably in CM, one
2870 :     already knows the intended argument but wants to delay the actual
2871 :     assignment until a time when error recovery would be more difficult.)
2872 :    
2873 :     Changed the handling of controls in tool arguments to classes "sml" and
2874 :     "lazysml":
2875 :     - use Controls.save'restore as a more robust way of restoring the
2876 :     old value (in particular: without having to re-parse the string)
2877 :     - use controls to handle the "overload" keyword in the init group
2878 :     (I believe this change actually fixes a long-standing obscure bug.)

2884 :     Description:
2885 :    
2886 :     Added a new tool class called "lazysml" to CM's tool chest. The only
2887 :     difference to "sml" is that compilation is done with Control.lazysml
2888 :     set to true. A source of class "lazysml" is automatically recognized
2889 :     by a file name suffix of ".lml".
2890 :    
2891 :     In addition to the above feature, the original class "sml" now also
2892 :     supports a tool argument "lazy" which has the same effect. As a
2893 :     result, the following three lines are equivalent:
2894 :    
2895 :     foo.sml : lazysml
2896 :     foo.sml : sml (lazy)
2897 :     foo.sml (lazy)
2898 :    
2899 :     The setting goes into effect both during parsing and during
2900 :     compilation. The original setting is restored right after parsing and
2901 :     after compilation, respectively.
2902 :    
2903 :     In addition to all the above, there is also a general mechanism to set
2904 :     ANY of the "controls" that are available at the command line via
2905 :     "-C..." on a per-sml-file basis. The same rules that apply for "lazy"
2906 :     apply as well. (In fact, "lazy" is implemented as a special case of
2907 :     the general mechanism.)
2908 :    
2909 :     The .cm file syntax uses a new keyword tool argument called "with".
2910 :     There are several ways of indicating the desired settings:
2911 :    
2912 :     foo.sml (with:parser.quotations=true)
2913 :     foo.sml (with:(name:parser.quotations value:true))
2914 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2915 :     foo.sml (with:(name1=value1 name2=value2 ...))
2916 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2917 :    
2918 :     etc.
2919 :    
2920 :     Another possible abbreviation is to leave out the =v or value:v part
2921 :     if the name refers to a boolean control (in which case the value is
2922 :     taken to be true). Thus, one could get lazy sml also by saying:
2923 :    
2924 :     foo.sml (with:parser.lazy-keyword=true)
2925 :     foo.sml (with:parser.lazy-keyword)
2926 :     foo.sml (with:(name:parser.lazy-keyword value:true))
2927 :     foo.sml (with:(name:parser.lazy-keyword))

3287 :     fresh streams whenever they are called -- as opposed to have them

3296 :    
3297 :     The proc value hangs on to the most recently created stream(s).
3298 :     Reap closes those. If either or both of the two streams hadn't
3299 :     been created at all yet, then reap will close the corresponding
3300 :     file descriptors directly.
3301 :    
3302 :     PS: I don't understand the original space leak argument anymore. If
3303 :     a proc hangs on to the imperative stream, then I/O operations on those
3304 :     will advance the state of the cached stream and avoid the space leak.

3318 :     Description:
3319 :    
3320 :     CM now ignores (but still accepts) the "owner" information in group
3321 :     descriptions. The owner of a group is its next enclosing
3322 :     library. Each group must have a unique owner. (There is a virtual
3323 : mblume 1505 "toplevel" library that owns groups which are not nested within a real
3324 : mblume 1498 library.) Previously, each group had to explicitly declare its owner,
3325 :     and CM would check that such a declaration is correct. The new scheme
3326 :     is to have CM check that for each group there is precisely one owning
3327 :     library.
3328 :    
3329 :     The advantage of the new scheme is that the programmer no longer needs
3330 :     to maintain the somewhat annoying owner information. The downside is
3331 :     that CM cannot enforce the ownership rule across multiple runs of
3332 :     CM.make. Fortunately, enclosing the same group in two different
3333 :     libraries A and B which are not part of the same program does not
3334 :     cause real problems.

3353 :     Description:
3354 :    
3355 :     Arranged for ml-build to clean up after itself a little bit better.
3356 :     The script generates a temporary SML source file and compiles it using
3357 :     CM, so CM generates metadata (GUID, SKEL, objectfile) for it. It now
3358 :     gets rid of those at the end, so they don't accumulate under .cm.
3359 :    
3360 :     This required a minor change to install.sh because the name of the
3361 :     metadata directory (default: .cm) is actually configurable at
3362 :     installation time.

3378 :    
3379 :     Added previously missing support for many socket-related functions
3380 :     under win32. Thanks to David Hansel <hansel@reactive-systems.com>
3381 :     for the voluminous patch!
3382 :    
3383 :     (I have not tested this patch under win32 yet.)
3384 :    
3385 : mblume 1490 Here is David's e-mail:
3386 :    
3387 :     Hi,
3388 :    
3389 :     Attached to this email you find a diff against sml/nj 110.45
3390 :     that will enable socket support under Windows.
3391 :    
3392 :     To apply the patch (using unix or cygwin)
3393 :     1) gunzip runtime.diff.gz
3394 :     2) "cd" into "src/runtime" in the source tree of a fresh
3395 :     110.45 installation.
3396 :     3) patch -p 1 < [your/path/to]runtime.diff
3397 :    
3398 : blume 2155 The code compiles fine but has NOT yet been extensively tested.
3399 :     I only ran a few tests for basic socket client functionality
3400 :     (which worked fine). Especially the functions that use ioctl
3401 : mblume 1490 are not tested at all and might not work (see below).
3402 :    
3403 :     I implemented this since we want to move to a newer version of sml/nj
3404 :     but need socket support in order to use it. This is the first time I
3405 :     even had a look at the sml/nj source, so please review my changes
3406 :     before making this part of the distribution! Here are a few issues
3407 : blume 2155 that I think might be better for someone to solve who is more
3408 : mblume 1490 familiar with the sml/nj source (and socket programming):
3409 :    
3410 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
3411 :     exception since I could not figure out what the windows equivalent
3412 :     of these functions is
3413 :    
3414 :     - In sockets-osdep.h there are a some #include statements that are
3415 :     only used in a few files that include sockets-osdep.h
3416 :    
3417 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
3418 :     does not process its return value since I don't know how to
3419 :     report an error upwards.
3420 :    
3421 :     - It would probably be good to have a call to WSACleanup() when
3422 : blume 2155 the library is unloaded (if there is such a possibility).
3423 : mblume 1490 Otherwise I think Windows will take care of this automatically
3424 :     when the process finishes.
3425 :    
3426 :     - I used ioctlsocket() as a replacement for ioctl() but I have
3427 :     no idea if that is actually the proper replacement on Windows.
3428 :    
3429 :     - All these issues are marked in the code by "FIXME" comments.
3430 :    
3431 : blume 2155 We use sml/nj extensively in our products and are quite happy
3432 :     with it. I hope this contribution will help you.
3433 : mblume 1490
3434 :     Keep up the good work!

3519 : blume 2155 does not work on Windows unless we explicitly export symbols

3657 :     Description:
3658 :    
3659 :     I modified the read-eval-print loop so that the autoloader gets
3660 :     invoked whenever the prettyprinter tries to look up a symbol that
3661 :     is not currently defined in the toplevel environment but which
3662 :     appears in CM's autoload registry. As a result, we see far fewer of
3663 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3664 :    
3665 :     In addition to this I tried to clean up some pieces of the Basis
3666 :     implementation (e.g., Socket, Word8Array) in order to prevent other
3667 :     instances of these ?.Foo.Bar.xxx names from being printed.
3668 :    
3669 :     The mechanism that picks names for types still needs some work, though.
3670 :     (Right now it seems that if there is a type A.t which is defined to
3671 : mblume 1394 be B.u, but B is unavailable at toplevel, then A.t gets printed as
3672 :     "?.B.u" although the perhaps more sensible solution would be to use
3673 : mblume 1393 "A.t" in this case. In other words, the prettyprinter should follow
3674 :     a chain of DEFtycs not farther than there are corresponding toplevel
3675 :     names in the current environment.)

3686 :    
3687 :     sml -m $smlnj/installer.cm
3688 :    
3689 :     and everything happens automagically.
3690 :    
3691 :     Win32: ML code senses value of environment variable SMLNJ_HOME.
3692 :     Unix: ML code senses values of environment variables ROOT, CONFIGDIR,
3693 :     and BINDIR.
3694 :    
3695 :     The new scheme guarantees that the ML code responsible for the installation
3696 :     is in sync with the APIs of the main system. Also, the installer is
3697 :     somewhat faster because the installer script is precompiled.

3704 :    
3705 :     Added a signature SYNCHRONOUS_SOCKET to basis.cm. This is like SOCKET
3706 :     but excludes all non-blocking operations. Defined SOCKET (in Basis)
3707 :     and CML_SOCKET in terms of SYNCHRONOUS_SOCKET. Removed superfluous
3708 :     implementations of non-blocking operations from CML's Socket
3709 :     structure.

3714 :     Tag: blume-20030924-sockets
3715 :     Description:
3716 :    
3717 :     1. Fixed SOCKET API and implementation to match Basis spec.
3718 :     This required changing the internal representation of sockets to one
3719 :     that remembers (for each socket file descriptor) whether it is currently
3720 :     blocking or non-blocking. This state is maintained lazily (i.e., a system
3721 :     call is made only if the state actually needs to change).
3722 :    
3723 :     2. OS-specific details of sockets were moved into separate files, thus
3724 :     making it possible to unify the bulk of the socket implementations
3725 :     between Unix and Win32.
3726 :    
3727 :     3. CML's socket API changed accordingly.
3728 :     (Note that we need to remove non-blocking functions from this API
3729 :     since they are redundant in the case of CML!)
3730 :    
3731 :     4. CML's socket implementation now makes use of non-blocking functions
3732 :     provided by Basis, thus removing all OS-dependent code from this part
3733 :     of CML.
3734 :    
3735 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

3781 :

3847 :     Tag: blume-20030909-installer
3848 :     Description:
3849 :    
3850 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3851 :     Modified config/install.bat to take advantage of it. Also modified
3852 :     config/install.sh (and called it config/new-install.sh) to take advantage
3853 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3854 :     independent.)
3855 :    
3856 :     The installer can now install everything under Win32
3857 :     as well as under *nix as long as it compiles.
3858 :    
3859 :     Other changes:
3860 :    
3861 :     - made CML compile again under Win32
3862 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3863 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3864 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3865 :     same as type int; under Win32 it isn't
3866 :     - fixed some slice-related problems in the win32-specific parts of CML
3867 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3868 :     (under Win32, the volume name is case-insensitive, and the
3869 :     OS.Path code compares volume names for equality)

3886 : mblume 1350 Description:
3887 :    
3888 :     1. Changed interface to vectors and arrays in Basis to match
3889 :     (draft) Basis spec.
3890 :     2. Added signatures and implementations of slices according to
3891 :     Basis spec.
3892 :     3. Edited source code throughout the system to make it compile again
3893 :     under 1. and 2. (In some cases code had to be added to have it
3894 :     match the new signatures.)
3895 :     4. MLRISC should be backward-compatible: the copies of the originals
3896 :     of files that needed to change under 3. were retained, the .cm files
3897 :     check the compiler version number and use old versions when
3898 :     appropriate.
3899 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3900 :     dirstream -> string option (in accordance with Basis spec).
3901 :     6. When generating code that counts lines, ml-lex used function
3902 :     CharVector.foldli, taking advantage of its old interface.
3903 :     This has been replaced with the corresponding code from
3904 :     CharVectorSlice. (html-lex must be re-lexed!)
3905 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3906 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3907 :     8. Removed temporary additions (fromInternal, toInternal) from the
3908 :     (now obsolete) IntInf in smlnj-lib/Util.
3909 :     9. Cleaned up structure Byte.
3910 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3911 :     Cleaned/corrected implementation of Date.
3912 :     (Still need to check for correctness; implement better canonicalizeDate.)
3913 :     11. Added "scan" to signature IEEE_REAL.
3914 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3915 :     mod and rem when second operand is 2 (for parity checks).]
3916 :     13. Changed representation of type Time.time, using a single IntInf.int
3917 :     value counting microseconds. This considerably simplified the
3918 :     implementation of structure Time. We now support negative time
3919 :     values; scan and fromString handle signs.
3920 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3921 :     ArraySlice).

3926 :     Tag: blume-20030828-intinf
3927 :     Description:
3928 :    
3929 :     This is a major update which comes with a version number bump
3930 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
3931 :     and an implementation of IntInf in the Basis.
3932 :    
3933 :     There are a fairly large number of related changes and updates throughout
3934 :     the system:
3935 :    
3936 :     Basis:
3937 :     - Implemented IntInf.
3938 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
3939 : mblume 1348 - Added some missing Real64 operations, most notably Real.toLargeInt.
3940 : mblume 1347 - Added FixedInt as a synonym for Int32.
3941 :    
3942 :     compiler:
3943 :     * Added support for a built-in intinf type.
3944 :     - literals
3945 :     - pattern matching
3946 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
3947 :     - overloading on literals and operations
3948 :    
3949 :     This required adding a primitive type intinf, some additional
3950 :     primops, and implementations for several non-trivial intinf
3951 :     operations in Core. (The intinf type is completely abstract
3952 :     to the compiler; all operations get delegated back to the Core.)
3953 :    
3954 :     * Intinf equality is handled by polyequal. However, the compiler
3955 :     does not print its usual warning in this case (since polyequal
3956 :     is the right thing to do there).
3957 :    
3958 :     * Improved the organization of structure InlineT.
3959 :    
3960 :     * A word about conversion primops:
3961 :     If conversions involving intinf do not cancel out during
3962 : mblume 1348 CPS contract, then the compiler must insert calls to Core functions.
3963 : mblume 1347 Since all core access must be resolved already during the FLINT
3964 :     translate phase, it would be too late a the time of CPS contract
3965 : mblume 1348 to add new Core calls. For this reason, conversion primops
3966 : mblume 1347 for intinf carry two arguments: 1. the numeric argument that
3967 :     they are supposed to convert, and 2. the Core function that
3968 :     can help with this conversion if necessary. If CPS contract
3969 : mblume 1348 eliminates a primop, then the associated Core function becomes
3970 :     dead and goes away. Intinf conversion primops that do not get
3971 :     eliminated by CPS contract get rewritten into calls of their
3972 :     core functions by a separate, new phase.
3973 : mblume 1347
3974 :     interactive system:
3975 :     - Control.Print.intinfDepth controls max length of intinf constants
3976 :     being printed. (Analogous to Control.Print.stringDepth.)
3977 :     - Cleanup in printutil and pputil: got rid of unused stuff and
3978 :     duplicates; replaced some of the code with code that makes better
3979 :     use of library functionality.
3980 :    
3981 :     CM:
3982 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
3983 :     are no longer silent.
3984 :    
3985 :     CKIT:
3986 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
3987 :     in favor of LargeInt -- which is now the same as IntInf.
3988 :     CKIT-knowledgable people should check whether this is what's
3989 :     intended and otherwise change things back to using Int32 or
3990 :     FixedInt.
3991 :    
3992 :     Throughout the code:
3993 : mblume 1348 Started using IntInf.int literals and built-in operations
3994 : mblume 1347 (e.g., comparison with 0) where this seems appropriate.

4014 :     Description:
4015 :    
4016 :     Version number bumped to 110.42.9. NEW BOOTFILES!!!
4017 :    
4018 :     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
4019 :    
4020 :     This patch restores SML/NJ's ability to run under win32. There are a
4021 :     number of changes, including fixes for several bugs that had gone
4022 :     unnoticed until now:
4023 :    
4024 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
4025 :     trying to run the win32 version from within cygwin.)
4026 :    
4027 :     - There are a number of simple .bat scripts that substitute for their
4028 :     corresponding Unix shell-scripts. (See below.)
4029 :    
4030 :     - The internals of ml-build have been modified slightly. The main
4031 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
4032 :     using OS.Process.system, the ML process delegates this task back
4033 :     to the script. Otherwise problems arise in mixed environments such
4034 :     as Cygwin where scripts look and work like Unix scripts, but
4035 :     where OS.Process.system cannot run them.
4036 :    
4037 :     - In CM, the srcpath pickler used native pathname syntax -- which
4038 :     is incorrect in the case of cross-compilation. The new pickle format
4039 :     is independent of platform-specific naming conventions.
4040 :    
4041 :     - Path configuration files (such as lib/pathconfig) can now choose
4042 :     between native and standard syntax. Placing a line of the form
4043 :    
4044 :     standard!
4045 :    
4046 :     into the file causes all subsequent paths to be interpreted using
4047 :     CM standard pathname syntax (= Unix conventions); a line
4048 :    
4049 :     native!
4050 :    
4051 :     switches back to native style. This was needed so that
4052 :     path config files can be written portably, see src/system/pathconfig.
4053 :    
4054 :     - Runtime system:
4055 :    
4056 :     - win32-filesys.c: get_file_time and set_file_time now
4057 :     access modification time, not creation time.
4058 :    
4059 :     - I/O code made aware of new array representation.
4060 :    
4061 :     - Bug fixes in X86.prim.masm.
4062 :    
4063 :     - src/system/makeml made aware of win32. (For use under cygwin
4064 :     and other Unix-environments for windows.)
4065 :    
4066 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
4067 :     which caused BinIO.inputAll to fail consistently.
4068 :    
4069 :     .bat scripts:
4070 :    
4071 :     Windows .bat scripts assume that SMLNJ_HOME is defined.
4072 :    
4073 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
4074 :     applications (sml, ml-yacc, ml-lex).
4075 :     - ml-build.bat: analogous to ml-build.
4076 :     - config\install.bat: Analogous to config/install.sh. This requires
4077 :     that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
4078 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
4079 :     Moreover, sources for ml-lex and ml-yacc need to exist under src,
4080 :     and the bootfile hierarchy must have been unpacked under
4081 :     sml.boot.x86-win32.
4082 :     The script is very primitive and does a poor job at error checking.
4083 :     It only installs the base system, ml-lex, and ml-yacc. No other
4084 :     libraries are being installed (i.e., you get only those that
4085 :     are part of the compiler.)
4086 :     - link-sml.bat: analogous to .link-sml, but not currently used
4087 :    
4088 :     Unrelated bug fixes:
4089 :    
4090 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
4091 :     types.
4092 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
4093 :     otherwise.)

4116 :     Tag: blume-20030517-complete
4117 :     Description:
4118 :    
4119 :     Two changes:
4120 :    
4121 :     1. Added a flag for controlling whether non-exhaustive bindings will
4122 :     be treated as errors (default is false).
4123 :     2. Cleaned up the *entire* source tree so that CMB.make goes through
4124 :     without a single non-exhaustive match- or bind warning.

4129 :     Tag: blume-20030517-absyn
4130 :     Description:
4131 :    
4132 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
4133 :    
4134 :     This mainly affects the quality of error messages. However, some
4135 :     of the code is now more straightforward than before. (Treatment of
4136 :     the above four constructs in translate.sml is much simpler than
4137 :     the "macro-expansion" that was going on before. Plus, the mach-
4138 :     compiler no longer gets invoked just to be able to compile an
4139 :     if-expression.)
4140 :    
4141 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
4142 :     interactive loop.
