1 : jhr 3992 Standard ML of New Jersey Change Log
2 :     ====================================
3 :     The Fellowship of SML/NJ
4 : jhr 3998 {version}, {releasedate}:
5 : jhr 3992
6 : jhr 4002 This file documents changes to the Standard ML of New Jersey system since
7 :     March of 2000 (around Version 110.26). The change log primarily covers
8 :     the compiler, the compilation manager (*CM*), the *MLRISC* library, and
9 :     the runtime system. There are occasional entries about other components
10 :     (_e.g._, the *SML/NJ Library* and *ML-LPT*), but these components have
11 :     their own change logs that should be consulted.
12 :    
13 : jhr 3992 //////////////////////////////////////////////////////////////////////
14 :     This change log is in ASCII doc format. An HTML version of the
15 :     change log can be generated using the command
16 :    
17 : jhr 4049 make html
18 : jhr 3992
19 :     An entry should be made for _every_ commit to the repository.
20 :     The entries in this file will be used when creating the README
21 :     for new versions, so keep that in mind when writing the
22 :     description.
23 :    
24 :     The structure of the HISTORY is that there is a section for
25 :     each release, which starts with a section header of the form
26 :    
27 :     == Version xxx.yy; yyyy/mm/dd
28 :    
29 :     The content of a section is a list of entries. The form of an
30 :     entry should be:
31 :    
32 :     [yyy/mm/dd]::
33 :     +
34 : jhr 3995 Description ...
35 : jhr 3992 +
36 :     owner:[Your Name,URL]
37 :    
38 : jhr 3995 Note that we put "+" at the beginning of blank lines. Entries are items
39 :     in a labeled list and the "+" character keeps eveything in the same list
40 :     element.
41 :    
42 : jhr 3992 Here is a quick asciidoc cheat sheet:
43 :    
44 :     + new paragraph
45 :     *foo* bold "foo"
46 :     _foo_ italic "foo"
47 :     +foo+ teletype "foo"
48 :     http:/some.website.org/path[] URL
49 :     bugref:[123] displays as "#123" with
50 :     a link to the bug report.
51 : jhr 4134 reqref:[123] displays as "#123" with a
52 :     link to the feature request.
53 : jhr 3992 owner:[name,url] displays name with URL link.
54 :    
55 : jhr 3995 Sub lists should be bracketed with lines containing just "--".
56 : jhr 3992 Bulleted list items start with a single dash or one to five
57 :     asterisks followed by some white space then some text. Numberd
58 :     list items begin one to five period characters, followed by
59 :     some white space then the item text.
60 :    
61 : jhr 3995 Literal (verbatim) blocks are delimited by
62 :     .....................
63 :     stuff
64 :     .....................
65 :    
66 : jhr 3992 Superscripts and subscripts are denoted by putting ^ (or ~)
67 :     around the text to superscripted (superscripted). For example,
68 :     the number 256 can be written as 2^8^.
69 :    
70 :     SML source code displays can be included as source blocks:
71 :    
72 :     [source,sml]
73 :     ------------
74 :     structure Foo = struct val x = 1 end
75 :     ------------
76 :    
77 :     Source code will be stylized using the pygmentize (http://pygments.org)
78 :     tool.
79 :    
80 :     More information about asciidoc can be found at http://asciidoc.org.
81 :    
82 : jhr 4002 NOTE: the original HISTORY file was converted to ASCIIDOC using a Perl
83 :     script. This script gets the basic structure for entries correct,
84 :     but there still needs to be a fair bit of editing to add ASCIIDOC
85 :     markup, fix indentation issues, nested lists, etc. Working from most
86 :     recent to oldest, I've edited back to release 110.46 (2004/06/17).

95 : jhr 4126
96 : jhr 4060 //--------------------------------------------------------------------
97 : jhr 4157 [2015/10/04]::
98 :     +
99 :     Patched +base/compiler/FLINT/clos/closure.sml+ so that *Twelf* will
100 :     build again (bugref:[140]).
101 :     +
102 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
103 :    
104 :     //--------------------------------------------------------------------
105 : jhr 4141 [2015/09/28]::
106 :     +
107 : jhr 4151 Added support for a *Successor ML* tool to CM. This tool allows one
108 :     to specify that a source file +fool.sml+ is *Successor ML* source code in the
109 :     following ways:
110 :     +
111 :     --------
112 :     foo.sml : succ-ml
113 :     foo.sml : sml (succ-ml)
114 :     foo.sml (succ-ml)
115 :     --------

118 :    
119 :     //--------------------------------------------------------------------
120 :     [2015/09/28]::
121 :     +
122 : jhr 4147 Added the directory +base/old-basis+ to support backward-compatible
123 :     views of the *Basis Library*. You can use these by replacing the
124 :     line
125 :     +
126 :     --------
127 :     $/basis.cm
128 :     --------
129 :     +
130 :     with
131 :     +
132 :     --------
133 :     $/basis-2004.cm
134 :     --------
135 :     +
136 :     in your CM files.
137 :    
138 :     //--------------------------------------------------------------------
139 :     [2015/09/28]::
140 :     +
141 : jhr 4141 New implementation of +Date+ structure in the Basis, which fixes bugs
142 :     bugref:[138] (Incorrect behavior for Date.fromTimeLocal) and
143 :     bugref:[139] (Date.date is broken). Note that some more thought should
144 :     be given to the correct semantics of +Date.date+ when dealing with
145 :     offsets. For example, should an offset of +23 hours produce the same
146 :     date as an offset of -1 hours? Currently our implementation produces
147 :     different results (by a day) for these two situations.
148 :     +

150 :    
151 :     //--------------------------------------------------------------------
152 : jhr 4126 [2015/09/25]::
153 :     +
154 : jhr 4134 Implemented the changes for
155 :     https://github.com/SMLFamily/BasisLibrary/wiki/2015-003-Additional-operations-on-sequences[
156 : jhr 4147 Basis Library Proposal 2015-003]. This proposal added operations to
157 : jhr 4134 the following signatures:
158 :     +
159 :     [source,sml]
160 :     ------------
161 :     signature ARRAY
162 :     signature LIST
163 :     signature LIST_PAIR
164 :     signature MONO_ARRAY
165 :     signature MONO_VECTOR
166 :     signature OPTION
167 :     signature STRING
168 :     signature TEXT
169 :     signature VECTOR
170 :     ------------
171 :     +
172 :     and the following structures:
173 :     +
174 :     [source,sml]
175 :     ------------
176 :     structure Array : ARRAY
177 :     structure CharArray : MONO_ARRAY
178 :     structure CharVector : MONO_VECTOR
179 :     structure List : LIST
180 :     structure ListPair : LIST_PAIR
181 :     structure Option : OPTION
182 :     structure Real64Array : MONO_ARRAY
183 :     structure Real64Vector : MONO_VECTOR
184 :     structure String : STRING
185 :     structure Text : TEXT
186 :     structure Vector : VECTOR
187 :     structure Word8Array : MONO_ARRAY
188 :     structure Word8Vector : MONO_VECTOR
189 :     ------------
190 :     +
191 :     While it is very unlikely that these changes will break existing code, there are
192 : jhr 4139 a a couple scenarios in which the code might break. Namely, when use of +open+
193 :     introduces conflicts and when user code implements one of the affected Basis Library
194 :     signatures. Both of these examples occurred in the *SML/NJ* source code; the former
195 :     in the *ml-yacc* sources and the latter in the *MLRISC* sources.

198 :    
199 :     //--------------------------------------------------------------------
200 :     [2015/09/25]::
201 :     +
202 :     Added the optional implementations of +PackReal64Big+ and +PackReal64Little+.
203 : jhr 4126 This addition addresses feature request reqref:[82]
204 :     (Implementations of +PACK_REAL+ missing). The implementation
205 :     uses the approach suggested by
206 :     https://github.com/msullivan/sml-util/blob/master/libs/pack-real.sml[Michael Sullivan].

211 : jhr 4122 [2015/09/24]::
212 :     +
213 :     Fixed bug bugref:[45] (Compiler bug in specialize phase). This bug
214 :     was in +compiler/FLINT/opt/fcontract.sml+ and was the result of a bad
215 :     interaction between eta contraction and inlining. As part of the fix,
216 :     I cleaned up the code in this part of FLINT a bit.

244 :     +
245 : jhr 4105 Fixed bug bugref:[136] (Incorrect raising of exceptions in +Real.fmt+
246 :     and +Time.fmt+).
247 : jhr 4097 +
248 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]

250 :     //--------------------------------------------------------------------
251 : jhr 4105 [2015/08/14]::
252 :     +
253 :     Added +Either+ structure and +EITHER+ signature to Basis implementation
254 :     (https://github.com/SMLFamily/BasisLibrary/wiki/2015-002-Addition-of-Either-module[
255 :     Basis Library Proposal 2015-002]).

258 :    
259 :     //--------------------------------------------------------------------
260 : jhr 4086 [2015/07/23]::
261 :     +
262 : jhr 4098 Fixed bug bugref:[135] (Fails to build on Linux PowerPC).

267 : jhr 4076 [2015/07/08]::
268 :     +
269 : jhr 4077 Added Linux 4.* kernels to the list of operating systems recognized
270 :     by the ++.arch-n-opsys++ script (fixes bug bugref:[134]).
271 : jhr 4076 +
272 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
273 :    
274 :     //--------------------------------------------------------------------
275 : jhr 4074 [2015/06/11]::
276 :     +
277 :     Added Mac OS X 10.11 (El Capitan) to the list of operating systems
278 :     recognized by the ++.arch-n-opsys++ script.
279 :     +
280 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
281 :    
282 :     //--------------------------------------------------------------------
283 : jhr 4060 [2015/05/27]::
284 :     +
285 : jhr 4105 Added support for *Successor ML* lexical extensions. These can be enabled
286 : jhr 4107 using the command-line option ++-Cparser.succ-ml=true++ or by the assignment
287 : jhr 4062 +
288 :     [source,sml]
289 :     ------------
290 :     Control.succML := true;
291 :     ------------
292 :     +
293 :     at the REPL. The extensions are as follows:
294 : jhr 4105 +
295 : jhr 4060 --
296 : jhr 4105 - Underscore ("++_++") as a separator in numeric literals; __e.g.__, ++123_456++,
297 :     ++0wxff_ff_ff_f3++, ++123_456.1++, ...
298 : jhr 4060
299 :     - end-of-line comments, which are denoted using ++(*)++. End-of-line comments
300 :     properly nest into conventional block comments. For example, the following
301 :     block comment is well formed:
302 :     +
303 :     [source,sml]
304 :     ------------
305 :     (*
306 :     fun f x = x (*) my identity function *)
307 :     *)
308 :     ------------
309 :     +
310 : jhr 4062 - binary literals for both integers and words; __e.g.__, ++0b0101_1110++, or
311 : jhr 4060 ++0wb1101++.
312 :     --
313 : jhr 4105 +
314 :     This change is the beginning of a program to add *Successor ML* feature to *SML/NJ*;
315 :     See https://github.com/SMLFamily/Proposed-Definition-of-Successor-ML[] for more
316 :     details.

323 : jhr 3992 //--------------------------------------------------------------------
324 : dbm 4001 [2014/12/19]::
325 :     +
326 :     Major revision of the machinery for overloading resolution for both
327 :     operators (vars) and literals, now using a common mechanism. This fixes
328 :     bug bugref:[52] by improving the error message when an overloaded
329 : jhr 4049 operator is inconsistent with its context. Updated 23 files, including
330 : dbm 4001 major changes in +overload.sml+, +types.sml+, +unify.sml+, +elabcore.sml+,
331 :     +typesutil.sml+. The overload declaration is still used in
332 :     +pervasives.sml+, where the order of the specified instances of an
333 : jhr 4002 ordering determines the default interpretation (_i.e._, the first one).
334 : dbm 4001 +
335 :     The +SCHEME+ and +LITERAL+ forms of tyvars are replaced by a new
336 :     +OVLD+ form that tracks potential instantiations of the type of the
337 :     overloaded vars or literals.

342 : jhr 4002 [2014/12/18]::
343 :     +
344 :     Moved +base/NOTES/HISTORY+ file to +doc/src/changelog/HISTORY.txt+
345 :     and converted it to http://asciidoc.org[ASCIIDOC] format. Have also
346 :     moved the +README+ files from +base/READMES+ to +doc/src/release-notes+.
347 :     These changes are part of a general effort to rationalize and improve
348 :     the documentation of the *SML/NJ* system.

354 :     +
355 : jhr 4002 Preliminary cleanups before changes to overloading
356 :     +
357 : jhr 3994 Minor cleanup in +Elaborator/elaborate/elabcore+ (function +elabOVERLOADdec+)
358 :     and in +ElabData/types/typesutil.sml+ (function +matchScheme+). Preparing for
359 :     a new method of handling type checking of overloaded operators. [Note
360 :     that there is no reason for the options field of +OVLDvar+ to be a
361 :     reference -- it is never updated. Changing this requires corresponding
362 :     change in pickling.]
363 :     +
364 :     Also added an +etopdebugging+ flag (+ElabControl+) for debugging in
365 :     +elabtop.sml+. Modified ++elabcontrol.++{++sml++,++sig++} and
366 :     +elabtop.sml+. Also rearranged ast and absyn printing in +evalloop.sml+.

379 :     [2014/10/11]::
380 :     +
381 :     Added +-D_FILE_OFFSET_BITS=64+ flag to +x86-linux+ makefile. This flag
382 :     is necessary to avoid spurious +EOVERFLOW+ errors on some versions of
383 :     Linux. The problem appears to be limited to large file systems that

402 : jhr 4002 [2014/08/21]::

404 :     Created new +doc+ tree in *SML/NJ* repository. Currently this
405 :     tree just holds the sources for UNIX-style manual pages for
406 :     the command-line tools (fixing bug bugref:[35]). The documentation
407 :     is written using the http://asciidoc.org[ASCIIDOC] format. Use

418 : jhr 3992 [2014/08/19]::
419 :     +
420 :     Compiling the runtime system on *cygwin* was failing because the file
421 :     +exceptions.h+ was missing. It appears to have been part of previous
422 :     versions, so a version has been incorporated verbatim in the
423 :     file +runtime/mach-base/cygwin-fault.c+ file (fixes bug bugref:[125]).

428 :     [2014/08/19]::
429 :     +
430 : jhr 4002 Added the +actionToString'+ and +repairToString'+ functions
431 :     to the +AntlrRepair+ structure. These functions allow one to
432 : jhr 3992 specialize the printing of tokens based on whether they are
433 :     being added or deleted.

438 :     [2014/08/17]::
439 :     +

1376 :     Fixed some bugs in new Div code in +FLINT/trans/translate.sml+.
1377 :     +
1378 :     Also, changed the handling of "no core access": When +translate.sml+
1379 :     needs access to a core exception at a time when the core has not
1380 :     been set up yet (this only happens when compiling +system/smlnj/init/+*),
1381 :     then don't bother generating the corresponding tests.
1382 :     +
1383 :     The old scheme was to generate a bogus value to be used in place of
1384 :     the exception. Unfortunately, that confuses the plambda type checker.
1385 :     Moreover, it does not do any good, because at runtime we don't expect
1386 :     such an exception to be ever raised. (The code in +system/smlnj/init/+*
1387 :     has to be written very carefully with this in mind!)

1402 :     operations with an explicit test for zero division. This should
1403 :     fixe several regressions and makes it possible for downstream optimization

1430 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
1431 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
1432 :     +
1433 :     (In addition, CMB_REBUILD_MODE is defined for +makeml -rebuild+,
1434 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
1435 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
1436 :     while running +CMB.make+. The point is that the single symbol
1437 :     NO_PLUGINS is definde in all three cases.)
1438 :     +
1439 :     I changed the three locations within the sources that get compiled
1440 :     during +CMB.make+ where *ml-yacc* or *ml-lex* input is processed: When
1441 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
1442 :     is bypassed.
1443 :     +
1444 :     When bootstrapping new versions of the compiler, there can be
1445 :     situations where the plugin tools for *ml-yacc* and *ml-lex* (or *ml-ulex*)
1446 :     are not available or otherwise not operational. In this case one can
1447 :     manually define the NO_PLUGINS symbol prior to running +CMB.make()+. To
1448 :     do so, the following command should be issued at the interactive
1449 :     prompt:
1450 :     +
1451 :     [source,sml]
1452 :     ------------
1453 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
1454 :     ------------
1455 :     +
1456 :     A +CMB.make+ with NO_PLUGINS defined relies on the existence of the
1457 :     files that normally would be generated by *ml-yacc* and *ml-lex*.
1458 :     (Copies of these files are in the repository.)

1477 :     Changed the installation mechanism for CM tool plugins. These are
1478 :     just libaries and now get installed like ordinary libaries.
1479 :     +
1480 :     There are now a number of new installation targets that give some
1481 :     fine-grain control over what classes and suffixes are known, and what
1482 :     they will map to.
1483 :     See +config/targets+ for details.
1484 :     +
1485 :     The code that caused plugin installation as part of running a

1495 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
1496 :     CM fail if a shell tool reports a non-success exit status. If
1497 :     the control is set to true, then CM will press on after tool failures
1498 :     in the event that the target files exist (even though they are
1499 :     considered outdated). Turning the control to true can be useful for

1507 :     Merge of ml-lpt revisions for 110.64.
1508 :     +
1509 :     The name of several ml-lpt-lib modules has changed:
1510 :     +
1511 :     [grid="none",frame="none",width="50%",cols=">2,^1,<2"]
1512 :     |===============================================

1516 :     | +EBNF+ | => | +AntlrEBNF+
1517 :     |===============================================
1518 :     +
1519 :     The *ml-antlr* specification format has changed: declarations such as
1520 :     +%tokens+ and nonterminal definitions can occur *multiple* times in the
1521 :     same specification. The semantics are such that each new declaration
1522 :     extends the previous ones. This does not apply to +%start+ or +%name+,
1523 :     of course.
1524 :     +
1525 :     Importing a grammar via +%import+ now includes *all* declarations in from
1526 :     the imported grammar, except for +%name+, +%entry+, and +%start+. Tokens
1527 :     and nonterminals can be dropped using the new +%dropping+ clause of the
1528 :     +%import+ directive; the separate +%drop+ and +%extend+ have been removed.
1529 :     +
1530 :     We now allow optional type annotations on nonterminals, using the +%nonterms+
1531 :     directive as in *ml-yacc*.
1532 :     +
1533 :     The +refcell+ construct is now implemented using SML's regular reference
1534 :     cells, so the +:==+ and +!!+ notation has been deprecated.
1535 :     +
1536 :     The *ml-antlr* tool now does much more checking of specifications, and
1537 :     its error messages have been greatly improved. Error repair for
1538 :     generated parsers has been completely rewritten, and is now both
1539 :     much faster and more accurate.
1540 :     +
1541 :     *ml-ulex* is now more lenient with escape codes (non-SML-standard
1542 :     escape codes are now interpreted literally, so _e.g._, +\|+ denotes "+|+").
1543 :     Also, character classes may now include a "+-+" character at the beginning
1544 :     as is standard in most other regexp tools.
1545 :     +
1546 :     All of these changes are documented in the user guide, which has
1547 :     been updated and improved with this merge.

1566 :     +%tokens+ and nonterminal definitions can occur *multiple* times in the
1567 :     same specification. The semantics are such that each new declaration
1568 :     extends the previous ones. Grammar extension constructs have also
1569 :     changed. We now allow type annotations on nonterminals. Finally,
1570 :     the refcell construct is now implemented using SML's regular reference
1571 :     cells, so the +:==+ and +!!+ notation has been deprecated. All of these
1572 :     changes will appear in the 110.64 user guide for *ml-lpt*.
1573 :     +
1574 :     The *ml-antlr* tool now does much more checking of specifications, and
1575 :     its error messages have been greatly improved. There has also been
1576 :     some work on the error repair process for generated parsers, but this
1577 :     will be further improved in 110.64.

1753 :     For *ml-yacc* and *ml-lex* we continue to have permanently "plugged-in"
1754 :     CM tools. (It turns out to be too messy to do otherwise because

1765 :     command line arguments. This way, the init code in each .sml-file
1766 :     or library that is mentioned at the top level will see only

1827 :     [2006/12/08]::
1828 :     +
1829 :     Added code to CM's "standard shell tool" implementation which
1830 :     causes it to tolerate (with a warning) the situation where the shell
1831 :     command fails (_e.g._, due to the shell command's non-existence)
1832 :     as long as all target files exist.
1833 :     +
1834 :     This makes it possible to, _e.g._, build *ml-yacc* from sources even if
1835 :     svn checkout messed up the time stamps on files in such a way that
1836 :     +yacc.grm+ is younger than yacc.grm.sml or +yacc.grm.sig+. (*Ml-yacc*
1837 :     would be needed to re-process +yacc.grm+, but obviously it might not yet be
1838 :     available at that time.)

1918 :     (All pathnames are relative to the SML/NJ "root" directory.)
1919 :     +
1920 :     In addition, there is also a new
1921 :     +
1922 :     ...........
1923 :     ml-lpt
1924 :     ...........
1925 :     +
1926 :     directory containing two new program generator tools: *ml-ulex* and
1927 :     *ml-antlr* (a lexer generator that handles unicode and an ANTRL-inspired
1928 :     LL(k) parser generator). These tools are currently "beta-quality"
1929 :     +
1930 :     The latest versios of the sources can now be obtained anonymously
1931 :     via subversion. For this, it is useful to first check out
1932 :     +
1933 :     ...........
1934 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1935 :     ...........
1936 :     +
1937 :     and put the resulting directory on your shell's PATH. This provides
1938 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
1939 :     and refresh-all.sh.
1940 :     +
1941 :     To create a freshly checked-out copy of the sources, do
1942 :     +
1943 :     ...........
1944 :     checkout-all.sh [dir]
1945 :     ...........
1946 :     +
1947 :     where dir is the optional SML/NJ root directory (default is ".").
1948 :     +
1949 :     This creates the above directory layout. Each subdirectory of
1950 :     the root is under individual subversion control. The stat-all.sh
1951 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
1952 :     each of these subtrees.

1955 :    
1956 :     //--------------------------------------------------------------------
1957 :     [2006/11/02]::
1958 :     +
1959 :     Reorganized directory layout.
1960 :     +
1961 :     This is a temporary solution, more reorganization is to come.
1962 :     +
1963 :     The basic idea is to have a number of toplevel trees, each corresponding
1964 :     to a well-defined part of the overall system. Each part can be
1965 :     maintained individually, even in separate source repositories,
1966 :     although currently we still serve everything out of the main
1967 :     smlnj-gforge tree.
1968 :     +
1969 :     Installer and and scripts have been updated to reflect the new
1970 :     layout. The installer (base/src/system/smlnj/installer) is now
1971 :     "scriptable" to avoid burning too much knowledge about the
1972 :     layout into SML source code. The main script used by the installer
1973 :     is in config/actions.
1974 :     +
1975 :     The main change is that many of the subdirectories of what used to
1976 :     be known as "src" have moved to the toplevel. The "src" directory
1977 :     itself has moved down into a subtree called "base". (We may eventually
1978 :     get rid of the extra level of indirection represented by "src".)
1979 :     +
1980 :     The layout is now as follows:
1981 :     +
1982 : jhr 4002 [frame="none",width="90%",cols="<2,<3",options="header"]

2007 :     +
2008 :     In +$gf/admin+ there are a few useful shell scripts for checking out
2009 : jhr 3992 and maintaining the entire collection of trees:
2010 :     +
2011 : jhr 4002 --
2012 :     +admin/checkout-all.sh+ [__dir__]::
2013 : jhr 3992 +
2014 : jhr 4002 optionally creates _dir_ and checks out all trees from their
2015 :     default repositories; if _dir_ is missing, checkout into the
2016 :     current working directory.
2017 :     +
2018 :     +admin/refresh-all.sh+ [__dir__]::
2019 :     looks at all trees (from the above list) in _dir_ (default: .)
2020 :     and runs "+svn update+" if the tree exists and is under
2021 :     subversion control;
2022 :     non-existing or non-subversion trees are skipped
2023 :     +
2024 :     +admin/stat-all.sh+ [__dir__]::
2025 :     like +refresh-all.sh+, but runs "+svn stat+" instead

2249 :     +
2250 : jhr 4002 Reversed change to +src/system/smlnj/internals/versiontool.cm+. This
2251 : jhr 3992 file gets loaded as a tool -- by the equivalent of CM.make during the
2252 : jhr 4002 run of +CMB.make+. Thus, CMB's path configuration is meaningless for
2253 : jhr 3992 it. Instead, it has the status of "user code", so it should use
2254 : jhr 4002 +$/basis.cm+ to refer to the Basis library. (At least that's true for
2255 : jhr 3992 the purpose of bootstrapping the previous change. In the future it
2256 : jhr 4002 might make sense to have +versiontool.cm+ refer to
2257 :     +$smlnj/basis/basis.cm+, _i.e._, the version of the Basis that the
2258 : jhr 3992 compiler itself uses.)
2259 :     +
2260 : jhr 4002 Also patched +src/system/testml+ to have it activate those extra anchor
2261 :     bindings in +config/extrapathconfig+.

2265 :     //--------------------------------------------------------------------
2266 :     [2005/11/15]::
2267 :     +
2268 :     This change affects the way the following libraries are tied into
2269 :     the system:
2270 :     +
2271 : jhr 4002 ....................
2272 : jhr 3992 $/basis.cm
2273 :     $/smlnj-lib.cm
2274 :     $/pp-lib.cm
2275 :     $/controls-lib.cm
2276 :     $/html-lib.cm
2277 :     $/ml-yacc-lib.cm
2278 : jhr 4002 ....................
2279 : jhr 3992 +
2280 :     These libraries are now internally (as seen from the source code
2281 :     of the implementation itself) known by the following names:
2282 :     +
2283 : jhr 4002 ....................
2284 : jhr 3992 $smlnj/basis/basis.cm
2285 :     $smlnj/smlnj-lib/smlnj-lib.cm

2288 :     $smlnj/smlnj-lib/html-lib.cm
2289 :     $smlnj/ml-yacc/ml-yacc-lib.cm
2290 : jhr 4002 ....................
2291 : jhr 3992 +
2292 :     This makes it possible to work with code that requires different
2293 :     versions of these libraries, and which refers to these libraries using
2294 :     their "default" names (_i.e._, the first set of names above). In other
2295 :     words, one can un-define or re-define those default names without
2296 :     compromising the proper functioning of the compiler itself.
2297 :     +
2298 :     A similar procedure had already been performed for several of the
2299 : jhr 4002 *MLRISC* libraries that are linked into the compiler. I did some
2300 : jhr 3992 cleanup on this code.
2301 :     +
2302 :     A new file in the config directory (named extrapathconfig) is
2303 :     responsible for setting up path anchors that the compiler itself does
2304 :     not need, but that are typically required by user code.

2476 : jhr 4002 [source,sml]
2477 :     ------------
2478 : jhr 3992 CM.redump_heap : string -> unit
2479 : jhr 4002 ------------
2480 : jhr 3992 +
2481 : jhr 4002 This is much like +SMLofNJ.exportML+, but starting from the resulting
2482 :     heap does not return to the caller of +CM.redump_heap+ but
2483 : jhr 3992 restarts the interactive system from scratch. The original call of
2484 : jhr 4002 +CM.redump_heap+ does not return but ends the interactive session.
2485 :     Thus, +CM.redump_heap+ is a lot like +SMLofNJ.exportFn+.
2486 : jhr 3992 +
2487 : jhr 4002 Internally, +redump_heap+ winds the dynamic execution context back to
2488 : jhr 3992 the point where the original heap image was created and re-executes
2489 :     the heap image generation code in the boot code.

2808 :     - In a previous commit, fixed a minor issue with how polyequal is being
2809 :     translated. In particular, the code now "looks through" abstractions.
2810 :     This results in slightly fewer polyEqual warnings and hopefully slightly
2811 :     more efficient code. Important examples for where this matters are

2829 :     but for the time being they don't even make sense because +LargeWord+ is
2830 : jhr 3992 32-bit wide.)
2831 :     +
2832 : jhr 3995 Also started to add similar support for +Int64+, but major pieces of that
2833 : jhr 3992 are still missing.

2838 :     [2004/11/11]::
2839 :     +
2840 : jhr 3995 Structure +Word64+ is now (almost) complete, word literals and patterns
2841 : jhr 3992 seem to work. There are a few odd pieces missing. In particular,
2842 : jhr 3995 I didn't do the {++from++,++to++}++LargeWord++ parts because +LargeWord+
2843 :     is still +Word32+ at the moment.
2844 : jhr 3992 +
2845 : jhr 3995 Making +Word64+ official would mean that +LargeWord+ becomes +Word64+. But
2846 : jhr 3992 this requires extreme care because most word-word conversions have to
2847 : jhr 3995 go through +LargeWord+, so making a mistake means loss of efficiency or
2848 : jhr 3992 worse. Eventually there will be a solution similar to (but actually
2849 : jhr 3995 simpler than) what I did with +IntInf+.

2923 :     Added a mechanism for getting back-trace information from standalone
2924 :     programs. Here is how it works:
2925 :     +
2926 : jhr 4002 --
2927 :     . The part of the program from which you want to get backtrace
2928 :     information (usually the whole program) should be wrapped with
2929 :     BackTrace.monitor. This is a +(unit->'a)->'a+ function, and your
2930 :     main program could be modified from something like
2931 : jhr 3992 +
2932 : jhr 4002 [source,sml]
2933 :     ------------
2934 :     fun main (pgm, args) = ...

2942 :     ------------
2943 : jhr 3992 +
2944 : jhr 4002 . To be able to access +BackTrace.monitor+, you have to add the
2945 :     library +$smlnj-tdp/plugins.cm+ to the +.cm+ file that contains your
2946 :     main function.
2947 : jhr 3992 +
2948 : jhr 4002 . Remove all compiled code (_i.e._, all the .cm/ subdirectories that
2949 :     *CM* might have created in the past for your project).

2994 : jhr 3992 * Test coverage tool added!
2995 :     * Further reorganization of tracing-, debugging-, and profiling support:
2996 :     +
2997 :     - moved original BTImp -- now called BackTrace -- into a separate
2998 :     library called $/trace-debug-profile.cm
2999 :     - eliminated all mentions of BTrace from SMLofNJ.Internals

3008 :     (The ref cell is also controlled via the +-Ctdp.instrument=...+ switch.)
3009 : jhr 3992 +
3010 :     Plugins are selected at link time. (Pre-compiled instrumented code
3011 :     can be re-loaded with different plugins in effect.) When an
3012 :     instrumented module is linked, whatever plugins are at that time
3013 :     enabled will come into effect for that module.
3014 :     +
3015 : jhr 4002 To enable the back-trace plugin, load library +$/trace-debug-profile.cm+
3016 :     and invoke +BackTrace.install()+ (_e.g._, from the interactive prompt).
3017 : jhr 3992 To enable the coverage plugin, load the same library and invoke
3018 : jhr 4002 +Coverage.install()+.
3019 : jhr 3992 +

3133 :     [2004/09/29]::
3134 :     +
3135 :     Implemented some CM magic to have
3136 :     file src/compiler/TopLevel/main/version.sml
3137 :     generated automagically.
3138 :     The version is taken from two files: config/version and config/release.
3139 :     The first is expected to contain a two-part version number such as 110.49.
3140 :     The second should contain a single number, but it may be missing.
3141 :     +
3142 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
3143 :     time the version tool is loaded (which is the first time you say CMB.make),
3144 :     then the tool will increment the value stored in config/release every
3145 :     time CMB.make is invoked.
3146 :     +
3147 :     The binfile format is now insensitive to anything beyond the first
3148 :     two components of a version number, so bumping the release does not render
3149 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
3150 :     during development without invalidating existing binfiles.

3165 :     [2004/09/27]::
3166 :     +
3167 :     Added two pieces of functionality to the Controls interface:
3168 :     +
3169 : jhr 3995 [source,sml]
3170 :     ------------
3171 :     val save'restore: 'a control -> unit -> unit
3172 :     ------------
3173 : jhr 3992 +
3174 : jhr 3995 grabs the current value of the control in stage 1 and restores it
3175 :     in stage 2.
3176 : jhr 3992 +
3177 : jhr 3995 [source,sml]
3178 :     ------------
3179 :     val set' : 'a control * 'a -> unit -> unit
3180 :     ------------
3181 : jhr 3992 +
3182 : jhr 3995 stores the given value into the control in stage 2 (_i.e._, delayed)
3183 :     but does all error checking in stage 1.
3184 :     (This is for string controls that need to do parse their argument --
3185 :     something that might fail. In some cases, notably in CM, one
3186 :     already knows the intended argument but wants to delay the actual
3187 :     assignment until a time when error recovery would be more difficult.)
3188 : jhr 3992 +
3189 : jhr 3995 Also changed the handling of controls in tool arguments to classes "+sml+" and
3190 :     "+lazysml+":
3191 : jhr 4002 +
3192 : jhr 3995 --
3193 :     - use +Controls.save'restore+ as a more robust way of restoring the
3194 : jhr 3992 old value (in particular: without having to re-parse the string)
3195 : jhr 3995 - use controls to handle the "+overload+" keyword in the init group
3196 : jhr 3992 (I believe this change actually fixes a long-standing obscure bug.)

3198 : jhr 3992 +

3201 :     //--------------------------------------------------------------------
3202 :     [2004/09/27]::
3203 :     +
3204 : jhr 3995 Added a new tool class called "+lazysml+" to CM's tool chest. The only
3205 :     difference to "+sml+" is that compilation is done with +Control.lazysml+
3206 :     set to true. A source of class "+lazysml+" is automatically recognized
3207 :     by a file name suffix of "+.lml+".
3208 : jhr 3992 +
3209 : jhr 3995 In addition to the above feature, the original class "+sml+" now also
3210 :     supports a tool argument "+lazy+" which has the same effect. As a
3211 : jhr 3992 result, the following three lines are equivalent:
3212 :     +
3213 : jhr 3995 ....................
3214 : jhr 3992 foo.sml : lazysml
3215 :     foo.sml : sml (lazy)
3216 :     foo.sml (lazy)
3217 : jhr 3995 ....................
3218 : jhr 3992 +
3219 :     The setting goes into effect both during parsing and during
3220 :     compilation. The original setting is restored right after parsing and
3221 :     after compilation, respectively.
3222 :     +
3223 :     In addition to all the above, there is also a general mechanism to set
3224 :     ANY of the "controls" that are available at the command line via
3225 : jhr 3995 "+-C...+" on a per-sml-file basis. The same rules that apply for "+lazy+"
3226 :     apply as well. (In fact, "+lazy+" is implemented as a special case of
3227 : jhr 3992 the general mechanism.)
3228 :     +
3229 : jhr 3995 The +.cm+ file syntax uses a new keyword tool argument called "+with+".
3230 : jhr 3992 There are several ways of indicating the desired settings:
3231 :     +
3232 : jhr 3995 ....................
3233 : jhr 3992 foo.sml (with:parser.quotations=true)
3234 :     foo.sml (with:(name:parser.quotations value:true))
3235 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
3236 :     foo.sml (with:(name1=value1 name2=value2 ...))
3237 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
3238 : jhr 3995 ....................
3239 : jhr 3992 +
3240 : jhr 3995 Another possible abbreviation is to leave out the +=v+ or +value:v+ part
3241 : jhr 3992 if the name refers to a boolean control (in which case the value is
3242 :     taken to be true). Thus, one could get lazy sml also by saying:
3243 :     +
3244 : jhr 3995 ....................
3245 : jhr 3992 foo.sml (with:parser.lazy-keyword=true)
3246 :     foo.sml (with:parser.lazy-keyword)
3247 :     foo.sml (with:(name:parser.lazy-keyword value:true))
3248 :     foo.sml (with:(name:parser.lazy-keyword))

3586 :     +
3587 :     Changed the interface of structures Timer and Unix to match the most
3588 :     recent Basis spec.
3589 :     +
3590 :     In the case of Unix there still seems to be an open/weird issue:
3591 :     +
3592 :     The {text,bin}{In,Out}streamOf functions are supposed to create
3593 :     fresh streams whenever they are called -- as opposed to have them
3594 :     return the same stream every time. This design is supposed to
3595 :     prevent space leaks caused by proc values hanging on to streams.
3596 :     +
3597 :     The reap function, on the other hand, is supposed to close the
3598 :     streams. This cannot be done without having a handle on the
3599 :     stream in proc after all...
3600 :     +
3601 :     I took the liberty to implement the following stopgap solution:
3602 :     +
3603 :     The proc value hangs on to the most recently created stream(s).
3604 :     Reap closes those. If either or both of the two streams hadn't
3605 :     been created at all yet, then reap will close the corresponding
3606 :     file descriptors directly.
3607 :     +
3608 :     PS: I don't understand the original space leak argument anymore. If
3609 :     a proc hangs on to the imperative stream, then I/O operations on those
3610 :     will advance the state of the cached stream and avoid the space leak.

3623 :     +
3624 :     CM now ignores (but still accepts) the "owner" information in group
3625 :     descriptions. The owner of a group is its next enclosing
3626 :     library. Each group must have a unique owner. (There is a virtual
3627 :     "toplevel" library that owns groups which are not nested within a real
3628 :     library.) Previously, each group had to explicitly declare its owner,
3629 :     and CM would check that such a declaration is correct. The new scheme
3630 :     is to have CM check that for each group there is precisely one owning
3631 :     library.
3632 :     +
3633 :     The advantage of the new scheme is that the programmer no longer needs
3634 :     to maintain the somewhat annoying owner information. The downside is
3635 :     that CM cannot enforce the ownership rule across multiple runs of
3636 :     CM.make. Fortunately, enclosing the same group in two different
3637 :     libraries A and B which are not part of the same program does not
3638 :     cause real problems.

3686 :     +
3687 :     Hi,
3688 :     +
3689 :     Attached to this email you find a diff against sml/nj 110.45
3690 :     that will enable socket support under Windows.
3691 :     +
3692 :     To apply the patch (using unix or cygwin)
3693 :     1) gunzip runtime.diff.gz
3694 :     2) "cd" into "src/runtime" in the source tree of a fresh
3695 :     110.45 installation.
3696 :     3) patch -p 1 < [your/path/to]runtime.diff
3697 :     +
3698 :     The code compiles fine but has NOT yet been extensively tested.
3699 :     I only ran a few tests for basic socket client functionality
3700 :     (which worked fine). Especially the functions that use ioctl
3701 :     are not tested at all and might not work (see below).
3702 :     +
3703 :     I implemented this since we want to move to a newer version of sml/nj
3704 :     but need socket support in order to use it. This is the first time I
3705 :     even had a look at the sml/nj source, so please review my changes
3706 :     before making this part of the distribution! Here are a few issues
3707 :     that I think might be better for someone to solve who is more
3708 :     familiar with the sml/nj source (and socket programming):
3709 :     +
3710 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
3711 :     exception since I could not figure out what the windows equivalent
3712 :     of these functions is
3713 :     +
3714 :     - In sockets-osdep.h there are a some #include statements that are
3715 :     only used in a few files that include sockets-osdep.h
3716 :     +
3717 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
3718 :     does not process its return value since I don't know how to
3719 :     report an error upwards.
3720 :     +
3721 :     - It would probably be good to have a call to WSACleanup() when
3722 :     the library is unloaded (if there is such a possibility).
3723 :     Otherwise I think Windows will take care of this automatically
3724 :     when the process finishes.
3725 :     +
3726 :     - I used ioctlsocket() as a replacement for ioctl() but I have
3727 :     no idea if that is actually the proper replacement on Windows.
3728 :     +
3729 :     - All these issues are marked in the code by "FIXME" comments.
3730 :     +
3731 :     We use sml/nj extensively in our products and are quite happy
3732 :     with it. I hope this contribution will help you.
3733 :     +

3879 :     Eliminated the "dont_move_libraries" directive in config/targets.
3880 :     (The mechanism was broken and could not be fixed easily. Moreover,
3881 :     there does not seem to be any reason not to move all libraries into
3882 :     lib during installation. I originally implemented this directive as a
3883 :     backward-compatibility feature when I first introduced the new CM.
3884 :     Now that things have been stable for a long time and going back to the
3885 :     old CM is not an option, there is no reason to keep it around.)

3924 :     //--------------------------------------------------------------------
3925 :     [2003/09/26]::
3926 :     +
3927 :     I modified the read-eval-print loop so that the autoloader gets
3928 :     invoked whenever the prettyprinter tries to look up a symbol that
3929 :     is not currently defined in the toplevel environment but which
3930 :     appears in CM's autoload registry. As a result, we see far fewer of
3931 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3932 :     +
3933 :     In addition to this I tried to clean up some pieces of the Basis
3934 :     implementation (_e.g._, Socket, Word8Array) in order to prevent other
3935 :     instances of these ?.Foo.Bar.xxx names from being printed.
3936 :     +
3937 :     The mechanism that picks names for types still needs some work, though.
3938 :     (Right now it seems that if there is a type A.t which is defined to
3939 :     be B.u, but B is unavailable at toplevel, then A.t gets printed as
3940 :     "?.B.u" although the perhaps more sensible solution would be to use
3941 :     "A.t" in this case. In other words, the prettyprinter should follow
3942 :     a chain of DEFtycs not farther than there are corresponding toplevel
3943 :     names in the current environment.)

3947 :     //--------------------------------------------------------------------
3948 :     [2003/09/24]::
3949 :     +
3950 :     Another installer tweak: All the ML code for the installer is now
3951 :     compiled during CMB.make and put into a little library called
3952 :     $smlnj/installer.cm. The installation then simply invokes
3953 :     +
3954 :     ....................
3955 :     sml -m $smlnj/installer.cm
3956 :     ....................
3957 :     +
3958 :     and everything happens automagically.
3959 :     +
3960 :     Win32: ML code senses value of environment variable +SMLNJ_HOME+.
3961 :     Unix: ML code senses values of environment variables +ROOT+, +CONFIGDIR+,
3962 :     and +BINDIR+.
3963 :     +
3964 :     The new scheme guarantees that the ML code responsible for the installation
3965 :     is in sync with the APIs of the main system. Also, the installer is
3966 :     somewhat faster because the installer script is precompiled.
3967 :     +

3969 : jhr 3992
3970 :     //--------------------------------------------------------------------
3971 :     [2003/09/24]::
3972 :     +
3973 :     Added a signature SYNCHRONOUS_SOCKET to basis.cm. This is like SOCKET
3974 :     but excludes all non-blocking operations. Defined SOCKET (in Basis)
3975 :     and CML_SOCKET in terms of SYNCHRONOUS_SOCKET. Removed superfluous
3976 :     implementations of non-blocking operations from CML's Socket
3977 :     structure.

3980 : jhr 3992
3981 :     //--------------------------------------------------------------------
3982 :     [2003/09/24]::
3983 :     +
3984 :     1. Fixed SOCKET API and implementation to match Basis spec.
3985 :     This required changing the internal representation of sockets to one
3986 :     that remembers (for each socket file descriptor) whether it is currently
3987 :     blocking or non-blocking. This state is maintained lazily (_i.e._, a system
3988 :     call is made only if the state actually needs to change).
3989 :     +
3990 :     2. OS-specific details of sockets were moved into separate files, thus
3991 :     making it possible to unify the bulk of the socket implementations
3992 :     between Unix and Win32.
3993 :     +
3994 :     3. CML's socket API changed accordingly.
3995 :     (Note that we need to remove non-blocking functions from this API
3996 :     since they are redundant in the case of CML!)
3997 :     +
3998 :     4. CML's socket implementation now makes use of non-blocking functions
3999 :     provided by Basis, thus removing all OS-dependent code from this part
4000 :     of CML.
4001 :     +
4002 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

4022 :     2. changed default CM "metadata" directory name to ".cm" (instead of "CM")
4023 :     3. tweaked installer so that another name instead of .cm can be chosen
4024 :     at install time (by setting the CM_DIR_ARC environment variable

4048 :     +
4049 :     2. Added Time.{from,to}Nanoseconds to Time.
4050 :     +
4051 :     3. Improved Real.{from,to}LargeInt by avoiding needless calculations.

4106 :     [2003/09/09]::
4107 :     +
4108 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
4109 :     Modified config/install.bat to take advantage of it. Also modified
4110 :     config/install.sh (and called it config/new-install.sh) to take advantage

4117 :     Other changes:
4118 :     +
4119 :     - made CML compile again under Win32
4120 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
4121 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
4122 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
4123 :     same as type int; under Win32 it isn't
4124 :     - fixed some slice-related problems in the win32-specific parts of CML
4125 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
4126 :     (under Win32, the volume name is case-insensitive, and the

4141 :     //--------------------------------------------------------------------
4142 :     [2003/09/04]::
4143 :     +
4144 :     1. Changed interface to vectors and arrays in Basis to match
4145 :     (draft) Basis spec.
4146 :     2. Added signatures and implementations of slices according to
4147 :     Basis spec.
4148 :     3. Edited source code throughout the system to make it compile again
4149 :     under 1. and 2. (In some cases code had to be added to have it
4150 :     match the new signatures.)
4151 :     4. MLRISC should be backward-compatible: the copies of the originals
4152 :     of files that needed to change under 3. were retained, the .cm files
4153 :     check the compiler version number and use old versions when
4154 :     appropriate.
4155 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
4156 :     dirstream -> string option (in accordance with Basis spec).
4157 :     6. When generating code that counts lines, *ml-lex* used function
4158 :     CharVector.foldli, taking advantage of its old interface.
4159 :     This has been replaced with the corresponding code from
4160 :     CharVectorSlice. (html-lex must be re-lexed!)
4161 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
4162 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
4163 :     8. Removed temporary additions (fromInternal, toInternal) from the
4164 :     (now obsolete) IntInf in smlnj-lib/Util.
4165 :     9. Cleaned up structure Byte.
4166 :     10. Added localOffset, scan, and fromString to Date (according to spec).
4167 :     Cleaned/corrected implementation of Date.
4168 :     (Still need to check for correctness; implement better canonicalizeDate.)
4169 :     11. Added "scan" to signature IEEE_REAL.
4170 :     12. Some improvements to IntInf [in particular: efficiency-hack for
4171 :     mod and rem when second operand is 2 (for parity checks).]
4172 :     13. Changed representation of type Time.time, using a single IntInf.int
4173 :     value counting microseconds. This considerably simplified the
4174 :     implementation of structure Time. We now support negative time
4175 :     values; scan and fromString handle signs.
4176 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
4177 :     ArraySlice).

4181 :     //--------------------------------------------------------------------
4182 :     [2003/08/28]::
4183 :     +
4184 :     This is a major update which comes with a version number bump
4185 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
4186 : jhr 4101 and an implementation of +IntInf+ in the Basis.
4187 :    
4188 : jhr 3992 There are a fairly large number of related changes and updates throughout
4189 :     the system:
4190 :     +
4191 :     Basis:
4192 :     - Implemented IntInf.
4193 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
4194 :     - Added some missing Real64 operations, most notably Real.toLargeInt.
4195 :     - Added FixedInt as a synonym for Int32.
4196 :     +
4197 :     compiler:
4198 :     * Added support for a built-in intinf type.
4199 : jhr 4101 --
4200 : jhr 3992 - literals
4201 :     - pattern matching
4202 : jhr 4101 - conversion shortcuts (+Int32.fromLarge o Int.toLarge+ etc.)
4203 : jhr 3992 - overloading on literals and operations
4204 : jhr 4101 --
4205 : jhr 3992 This required adding a primitive type intinf, some additional
4206 :     primops, and implementations for several non-trivial intinf
4207 :     operations in Core. (The intinf type is completely abstract
4208 :     to the compiler; all operations get delegated back to the Core.)
4209 :     +
4210 :     * Intinf equality is handled by polyequal. However, the compiler
4211 :     does not print its usual warning in this case (since polyequal
4212 :     is the right thing to do there).
4213 :     +
4214 : jhr 4101 * Improved the organization of structure +InlineT+.
4215 : jhr 3992 +
4216 :     * A word about conversion primops:
4217 :     If conversions involving intinf do not cancel out during
4218 :     CPS contract, then the compiler must insert calls to Core functions.
4219 :     Since all core access must be resolved already during the FLINT
4220 :     translate phase, it would be too late a the time of CPS contract
4221 :     to add new Core calls. For this reason, conversion primops
4222 :     for intinf carry two arguments: 1. the numeric argument that
4223 :     they are supposed to convert, and 2. the Core function that
4224 :     can help with this conversion if necessary. If CPS contract
4225 :     eliminates a primop, then the associated Core function becomes
4226 :     dead and goes away. Intinf conversion primops that do not get
4227 :     eliminated by CPS contract get rewritten into calls of their
4228 :     core functions by a separate, new phase.
4229 :     +
4230 :     interactive system:
4231 :     - Control.Print.intinfDepth controls max length of intinf constants
4232 :     being printed. (Analogous to Control.Print.stringDepth.)
4233 :     - Cleanup in printutil and pputil: got rid of unused stuff and
4234 :     duplicates; replaced some of the code with code that makes better
4235 :     use of library functionality.
4236 :     +
4237 :     CM:
4238 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
4239 :     are no longer silent.
4240 :     +
4241 :     CKIT:
4242 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
4243 :     in favor of LargeInt -- which is now the same as IntInf.
4244 :     CKIT-knowledgable people should check whether this is what's
4245 :     intended and otherwise change things back to using Int32 or
4246 :     FixedInt.
4247 :     +
4248 :     Throughout the code:
4249 :     Started using IntInf.int literals and built-in operations
4250 :     (_e.g._, comparison with 0) where this seems appropriate.

4258 :     Merging changes from the mcz-branch development branch into trunk.
4259 :     These changes involve replacement of the emulated old prettyprinter
4260 :     interface with direct use of the SML/NJ Lib PP library, and fixing
4261 :     of a couple of bugs (895, 1186) relating to error messages. A new
4262 :     prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
4263 :     has been added.

4274 :     This patch restores SML/NJ's ability to run under win32. There are a
4275 :     number of changes, including fixes for several bugs that had gone
4276 :     unnoticed until now:
4277 :     +
4278 : jhr 4101 --
4279 :     * uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
4280 :     trying to run the win32 version from within cygwin.)
4281 :    
4282 :     * There are a number of simple .bat scripts that substitute for their
4283 :     corresponding Unix shell-scripts. (See below.)
4284 :    
4285 :     * The internals of *ml-build* have been modified slightly. The main
4286 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
4287 :     using +OS.Process.system+, the ML process delegates this task back
4288 :     to the script. Otherwise problems arise in mixed environments such
4289 :     as Cygwin where scripts look and work like Unix scripts, but
4290 :     where OS.Process.system cannot run them.
4291 :    
4292 :     * In CM, the srcpath pickler used native pathname syntax -- which
4293 :     is incorrect in the case of cross-compilation. The new pickle format
4294 :     is independent of platform-specific naming conventions.
4295 :    
4296 :     * Path configuration files (such as lib/pathconfig) can now choose
4297 :     between native and standard syntax. Placing a line of the form
4298 : jhr 3992 +
4299 :     standard!
4300 :     +
4301 : jhr 4101 into the file causes all subsequent paths to be interpreted using
4302 :     CM standard pathname syntax (= Unix conventions); a line
4303 : jhr 3992 +
4304 :     native!
4305 :     +
4306 : jhr 4101 switches back to native style. This was needed so that
