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 4468 This file documents changes to the *Standard ML of New Jersey* system since
7 : jhr 4002 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 : dbm 4298 asterisks followed by some white space then some text. Numbered
58 : jhr 3992 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).

91 : jhr 4501 == Recent updates
92 : jhr 4220
93 : jhr 4501 //--------------------------------------------------------------------
94 : jhr 4596 [2018/05/13]::
95 :     +
96 :     Fixed a bug in the parsing of bindings involving the `op` keyword.
97 :     The parser was more restrictive than the definition. This change
98 :     fixes bug number 1370 from the old openbugs list.
99 :     +
100 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
101 :    
102 :     //--------------------------------------------------------------------
103 : jhr 4585 [2018/05/12]::
104 :     +
105 :     The lexer gave an unmatched close comment error on "++*)++", when it
106 : jhr 4596 should have scanned it as the tokens "++*++" "**)**". This change
107 :     fixes bug number 330 in the old openbugs list.
108 : jhr 4585 +
109 :     **Note**: there is some ambiguity as to what the correct behavior
110 :     should be here. The Definition of Standard ML (1997) only says that
111 :     unmatched __open__ comments should be signalled as errors, but the
112 :     Commentary on the Definition of Standard ML says otherwise in
113 :     Appendix D. **SML/NJ** started signalling an error in version 0.71,
114 :     but we choose to revert to accepting this sequence, since to match
115 :     the 1997 Definition.
116 :     +
117 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
118 :    
119 :     //--------------------------------------------------------------------
120 : jhr 4572 [2018/05/07]::
121 :     +
122 : jhr 4576 The `sameSign` function returned incorrect results in the `Int31`
123 :     and `Int32` modules.
124 :     +
125 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
126 :    
127 :     //--------------------------------------------------------------------
128 :     [2018/05/07]::
129 :     +
130 : jhr 4572 Fixed various minor parsing and scanning issues:
131 :     +
132 :     --
133 :     * correct syntax for type variables
134 :     * signature/structure/functor IDs should always be alpha IDs
135 : jhr 4596 * the equality ID (`=`) cannot appear in a binding context. Note that
136 :     we still allow the syntax `val op = = ...` because it is needed to
137 :     parse the file `system/smlnj/init/built-in.sml`.
138 : jhr 4572 --
139 :     +
140 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
141 :    
142 :     //--------------------------------------------------------------------
143 : jhr 4562 [2018/05/05]::
144 :     +
145 :     Completed overhaul of the way that int/word literals are handled in
146 :     the compiler. We now use `IntInf.int` to represent the values in
147 :     all IRs. This change also results in better CPS contraction, since
148 :     we now perform constant folding for both signed and unsigned values
149 :     at all sizes. We were also able to get rid of the tricky code that
150 :     worries about large tagged integer values that might cause overflow
151 :     during code generation.
152 :     +
153 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
154 :    
155 :     //--------------------------------------------------------------------
156 : jhr 4539 [2018/04/21]::
157 :     +
158 :     Improved the reporting of errors involving literal values. We now
159 :     use the original source text when describing the value in the error
160 :     message.
161 :     +
162 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
163 :    
164 :     //--------------------------------------------------------------------
165 : jhr 4533 [2018/04/20]::
166 :     +
167 :     Fix for bug bugref:[191] (Compiler crash when handling large reals).
168 :     We now issue a warning for real literals that will round to zero and
169 :     an error for real literals that are too large to represent. There
170 :     still needs to be done some work to support sub-normal literal values
171 :     (these are currently rounded to zero).
172 :     +
173 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
174 :    
175 :     //--------------------------------------------------------------------
176 : jhr 4528 [2018/04/14]::
177 :     +
178 :     Changed the representation of real literals from strings to ++RealLit.t++.
179 :     +
180 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
181 :    
182 :     //--------------------------------------------------------------------
183 : jhr 4524 [2018/04/13]::
184 :     +
185 :     Removed real patterns from Absyn and FLINT, since they are not allowed
186 :     by SML'93 and were not present in the AST representation.
187 :     +
188 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
189 :    
190 :     //--------------------------------------------------------------------
191 : jhr 4521 [2018/04/12]::
192 :     +
193 : jhr 4533 Fix for bug bugref:[194] (++Real.fromString++ overflows or hangs). There
194 : jhr 4521 were two issues here. First, the +Overflow+ exception was being raised
195 :     when scanning large exponents, but it was not being handled by the
196 : jhr 4596 scanning code. The second issue was that the scaling loop for large
197 :     exponents did not immediately terminate once infinity (or zero) was
198 :     reached, so it could take a long time.

201 :    
202 :     //--------------------------------------------------------------------
203 : jhr 4501 [2017/10/16]::
204 :     +
205 :     Moved the check for whether a int or word literal is in range for
206 :     its type from the absyn->plambda translation to the overload
207 :     resolver (++compiler/Elaborator/types/overload.sml++).
208 :     +

210 :    
211 :     //--------------------------------------------------------------------
212 :     [2017/10/14]::
213 :     +
214 :     Part 1 of an overhaul of the way that the compiler treats int/word
215 :     literals. The end goal is to use ++IntInf.int++ to represent literals
216 :     throughout all phases of the compiler. In this step, we changed the
217 :     representation of literals in the ++Absyn++ representation (earlier
218 :     representations already used IntInf.int).

223 :     == Version 110.82; 2017/10/16
224 :    
225 : jhr 4366 //--------------------------------------------------------------------
226 : jhr 4461 [2017/10/01]::
227 :     +
228 :     Fixed unnumbered bug in ++IntInf.mod++ and ++IntInf.rem++ functions,
229 :     where the ++Div++ exception was *not* getting raised when both
230 :     arguments are ++0++.
231 :     +
232 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
233 :    
234 :     //--------------------------------------------------------------------
235 : jhr 4467 [2017/09/20]::
236 :     +
237 : jhr 4468 Various bits of cleanup in the handling of primitive operations, such
238 :     as removing the +ptnum+ mechanism for translating from Absyn to FLINT.
239 :     +
240 :     owner:[David MacQueen,http://cs.uchicago.edu/~dbm]
241 :    
242 :     //--------------------------------------------------------------------
243 :     [2017/09/20]::
244 :     +
245 : jhr 4467 Added +Target+ module, which specifies the properties of the target
246 :     (__e.g.__, the size in bits of the default int type). Reworked the
247 :     generation of the +InlineT+ structure to be target specific.
248 :     +
249 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
250 :    
251 :     //--------------------------------------------------------------------
252 : jhr 4413 [2017/09/18]::
253 :     +
254 : jhr 4420 Removed FLINT primops (and their CPS counterparts) that are not
255 :     in the +InlineT+ structure and, thus, are never used by the compiler.
256 :     +
257 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
258 :    
259 :     //--------------------------------------------------------------------
260 :     [2017/09/18]::
261 :     +
262 : jhr 4417 Fixed bug bugref:[123] (missing nonexhaustive bind warning). The +mkVBs+
263 : jhr 4468 function in +FLINT/trans/translate.sml+ was adding a redundant default
264 : jhr 4417 rule by calling ++ElabUtil.completeMatch++ after a default rule had
265 :     already been explicitly added to the match for let bindings.

268 :    
269 :     //--------------------------------------------------------------------
270 :     [2017/09/18]::
271 :     +
272 : jhr 4414 Fixed bug bugref:[183] (status code returned by sml REPL). This fix
273 : jhr 4413 restores the version 110.79 behavior of having +sml foo.sml+ exit with
274 :     a non-zero status when there is a type-checking error in ++foo.sml++.
275 :     It also cleans up the error messages associated with +use+ when there
276 :     is a syntax error.
277 :     +
278 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
279 :    
280 :     //--------------------------------------------------------------------
281 : jhr 4399 [2017/08/28]::
282 :     +
283 :     Fixed bug bugref:[185] (Bring command line help text into parity with man page).
284 :     Added missing options (++@SMLversion++ and ++@SMLsuffix++) to the
285 :     help message that is printed for the command "++sml -h++". Also
286 :     adjusted the order of options in the help message, and in the man
287 :     page, so that the orders match.
288 :     +

290 :    
291 :     //--------------------------------------------------------------------
292 : jhr 4375 [2017/08/12]::
293 :     +
294 :     Changed the way that we test for allocation-space addresses in minor GCs.
295 :     Instead of using the BIBOP, we now do a pointer range test. On 32-bit
296 :     systems, this change results in a small (~0.13%) performance boost, but
297 :     we expect a bigger impact on 64-bit hardware, where the cost of BIBOP
298 :     probes will be higher and there are more registers available to hold
299 :     the nursery bounds.
300 :     +
301 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
302 :    
303 :     //--------------------------------------------------------------------
304 :     [2017/08/12]::
305 :     +
306 :     Fixed some issues in build-literals.c. These were mostly false
307 :     positives in the assertions, but there was also a bug in the way
308 :     that the available space was tracked that could conceivably
309 :     result in a crash (but was very unlikely).

313 :     //--------------------------------------------------------------------
314 : jhr 4368 [2017/06/07]::
315 :     +
316 :     Updated _arch-n-os script to recognize macOS 10.13 (High Sierra)
317 :     as a valid target.

321 :     //--------------------------------------------------------------------
322 : jhr 4366 [2017/05/17]::
323 :     +
324 :     Fixed a bug in the way that JSON string values were being printed.
325 : jhr 4468 The code previously assumed that C-style escaping will work, but
326 : jhr 4366 that is not true for "\'" (as well as for control and non-ASCII
327 :     characters). The new implementation assumes that the string value
328 :     is UTF-8 and uses the "\\u" escape sequences for characters outside
329 :     the JSON escapes and printable ASCII characters.

345 :     +
346 :     Fixed bug bugref:[179] (ml-ulex writing debug messages to stdOut).
347 :     Both **ml-ulex** and **ml-antlr** now direct their debug and status messages
348 :     to ++stdErr++ (instead of ++stdOut++).

353 :     [2017/02/09]::
354 :     +
355 : jhr 4322 Linux distributions are starting to require that the stack be marked
356 :     as non-executable in applications. Because the runtime system includes
357 :     assembly code, this marking was not happening. We've added ++.section++
358 :     directives to the ++PPC.prim.asm++ and ++X86.prim.asm++ files as
359 :     per https://wiki.gentoo.org/wiki/Hardened/GNU_stack_quickstart#Patching[].

368 :     Added ++--debug++ command-line option to *ml-antlr*.

387 : jhr 4317 Eliminated all references to +ModulePropLists+ (+module-plists.sml+) in

411 : jhr 4310 [2016/09/14]::
412 :     +
413 : jhr 4334 Eliminated dependency of ++PlambdaType++ from the front end by adding a
414 :     type ++TKind.tkind++ which is a simplified standin for ++PlambdaType.tkind++
415 :     for use during elaboration. ++TKind.tkind++ values are translated on
416 :     demand to ++PlambdaType.tkind++ in ++trans/transtypes.sml++. Types still has
417 :     a ++tycpath++ type but it is defined using ++TKind.tkind++ now. The new structure
418 :     ++SigPropList++ replaces ++ModulePropLists++
419 :     (++Semant/modules/module-plists.sml++) for use in ++instantiate.sml++.
420 :     ++Instantiate++ is now defined directly as a structure so the functor
421 :     application in ++Semant/modules/instantiate.sml++ no longer exists.

867 : jhr 4060 [2015/05/27]::
868 :     +
869 : jhr 4105 Added support for *Successor ML* lexical extensions. These can be enabled

873 :     ------------
874 :     Control.succML := true;
875 :     ------------
876 :     +
877 :     at the REPL. The extensions are as follows:
878 : jhr 4105 +
879 : jhr 4060 --
880 : jhr 4105 - Underscore ("++_++") as a separator in numeric literals; __e.g.__, ++123_456++,
881 :     ++0wxff_ff_ff_f3++, ++123_456.1++, ...
882 : jhr 4060
883 :     - end-of-line comments, which are denoted using ++(*)++. End-of-line comments
884 :     properly nest into conventional block comments. For example, the following
885 : jhr 4216 block comment is well formed:
886 : jhr 4060 +
887 :     [source,sml]
888 :     ------------
889 :     (*
890 :     fun f x = x (*) my identity function *)
891 :     *)
892 :     ------------
893 :     +
894 : jhr 4062 - binary literals for both integers and words; __e.g.__, ++0b0101_1110++, or
895 : jhr 4060 ++0wb1101++.
896 :     --
897 : jhr 4105 +
898 :     This change is the beginning of a program to add *Successor ML* feature to *SML/NJ*;

908 : dbm 4001 [2014/12/19]::
909 :     +
910 :     Major revision of the machinery for overloading resolution for both
911 : jhr 4216 operators (vars) and literals, now using a common mechanism. This fixes
912 : dbm 4001 bug bugref:[52] by improving the error message when an overloaded
913 : jhr 4049 operator is inconsistent with its context. Updated 23 files, including
914 : dbm 4001 major changes in +overload.sml+, +types.sml+, +unify.sml+, +elabcore.sml+,
915 :     +typesutil.sml+. The overload declaration is still used in
916 :     +pervasives.sml+, where the order of the specified instances of an
917 : jhr 4002 ordering determines the default interpretation (_i.e._, the first one).
918 : dbm 4001 +
919 :     The +SCHEME+ and +LITERAL+ forms of tyvars are replaced by a new
920 :     +OVLD+ form that tracks potential instantiations of the type of the
921 :     overloaded vars or literals.

941 : jhr 3994 Minor cleanup in +Elaborator/elaborate/elabcore+ (function +elabOVERLOADdec+)
942 :     and in +ElabData/types/typesutil.sml+ (function +matchScheme+). Preparing for

2168 :     More Basis fixes: The +Char.fromString+ (_etc._) functions did not handle
2169 :     the "+\uxxxx+" escape sequence. There is still an outstanding bug with
2170 :     +String.fromString+ the tail is a format escape. I added a comment to

2317 : jhr 4216 Brought ml-lpt manual up-to-date with the code. Many minor
2318 : jhr 3992 improvements to the tools, and a few minor bugfixes. Prepared
2319 :     ml-lpt-lib for integration with new +UTF8+ structure. Changed
2320 :     the interface for creating streams in *ml-ulex* (we now support
2321 : jhr 4216 stream creation from several kinds of sources). Overall, the
2322 :     tools are now quite stable, and their interfaces are unlikely to
2323 : jhr 3992 change in a way that would break compatibility. More work,
2324 :     however, is needed in the documentation.

2336 :     +
2337 :     For *ml-yacc* and *ml-lex* we continue to have permanently "plugged-in"
2338 :     CM tools. (It turns out to be too messy to do otherwise because
2339 :     there is too much code that during installation relies on the presence

2348 :     Modified CM's startup code to use +shiftArgs+ as it processes
2349 :     command line arguments. This way, the init code in each .sml-file
2350 :     or library that is mentioned at the top level will see only
2351 :     those arguments that have not yet been processed at this point.
2352 :     In other words, the init code can "seize control" and process the

2418 :     This makes it possible to, _e.g._, build *ml-yacc* from sources even if

2420 :     +yacc.grm+ is younger than yacc.grm.sml or +yacc.grm.sig+. (*Ml-yacc*

2507 :     ml-lpt
2508 :     ...........
2509 :     +
2510 :     directory containing two new program generator tools: *ml-ulex* and
2511 :     *ml-antlr* (a lexer generator that handles unicode and an ANTRL-inspired
2512 :     LL(k) parser generator). These tools are currently "beta-quality"
2513 :     +
2514 :     The latest versios of the sources can now be obtained anonymously

2518 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin

2523 :     and refresh-all.sh.
2524 :     +

2541 :     [2006/11/02]::
2542 :     +
2543 :     Reorganized directory layout.
2544 :     +
2545 :     This is a temporary solution, more reorganization is to come.
2546 :     +
2547 :     The basic idea is to have a number of toplevel trees, each corresponding
2548 :     to a well-defined part of the overall system. Each part can be
2549 :     maintained individually, even in separate source repositories,
2550 :     although currently we still serve everything out of the main
2551 :     smlnj-gforge tree.
2552 :     +
2553 :     Installer and and scripts have been updated to reflect the new
2554 :     layout. The installer (base/src/system/smlnj/installer) is now
2555 :     "scriptable" to avoid burning too much knowledge about the
2556 :     layout into SML source code. The main script used by the installer
2557 :     is in config/actions.
2558 :     +
2559 :     The main change is that many of the subdirectories of what used to
2560 :     be known as "src" have moved to the toplevel. The "src" directory
2561 :     itself has moved down into a subtree called "base". (We may eventually
2562 :     get rid of the extra level of indirection represented by "src".)
2563 :     +
2564 :     The layout is now as follows:
2565 :     +
2566 : jhr 4002 [frame="none",width="90%",cols="<2,<3",options="header"]

2833 :     +
2834 : jhr 4002 Reversed change to +src/system/smlnj/internals/versiontool.cm+. This
2835 : jhr 3992 file gets loaded as a tool -- by the equivalent of CM.make during the
2836 : jhr 4002 run of +CMB.make+. Thus, CMB's path configuration is meaningless for
2837 : jhr 3992 it. Instead, it has the status of "user code", so it should use
2838 : jhr 4002 +$/basis.cm+ to refer to the Basis library. (At least that's true for
2839 : jhr 3992 the purpose of bootstrapping the previous change. In the future it
2840 : jhr 4002 might make sense to have +versiontool.cm+ refer to
2841 :     +$smlnj/basis/basis.cm+, _i.e._, the version of the Basis that the
2842 : jhr 3992 compiler itself uses.)
2843 :     +
2844 : jhr 4002 Also patched +src/system/testml+ to have it activate those extra anchor

2850 :     [2005/11/15]::
2851 :     +
2852 :     This change affects the way the following libraries are tied into

2855 : jhr 4002 ....................
2856 : jhr 3992 $/basis.cm
2857 :     $/smlnj-lib.cm
2858 :     $/pp-lib.cm
2859 :     $/controls-lib.cm
2860 :     $/html-lib.cm
2861 :     $/ml-yacc-lib.cm
2862 : jhr 4002 ....................
2863 : jhr 3992 +
2864 :     These libraries are now internally (as seen from the source code
2865 :     of the implementation itself) known by the following names:
2866 :     +
2867 : jhr 4002 ....................
2868 : jhr 3992 $smlnj/basis/basis.cm
2869 :     $smlnj/smlnj-lib/smlnj-lib.cm

2873 :     $smlnj/ml-yacc/ml-yacc-lib.cm
2874 : jhr 4002 ....................
2875 : jhr 3992 +
2876 :     This makes it possible to work with code that requires different
2877 :     versions of these libraries, and which refers to these libraries using
2878 :     their "default" names (_i.e._, the first set of names above). In other
2879 :     words, one can un-define or re-define those default names without
2880 :     compromising the proper functioning of the compiler itself.
2881 :     +
2882 :     A similar procedure had already been performed for several of the
2883 : jhr 4002 *MLRISC* libraries that are linked into the compiler. I did some
2884 : jhr 3992 cleanup on this code.
2885 :     +
2886 :     A new file in the config directory (named extrapathconfig) is
2887 :     responsible for setting up path anchors that the compiler itself does
2888 :     not need, but that are typically required by user code.

3038 :     //--------------------------------------------------------------------
3039 :     [2005/05/18]::
3040 :     +
3041 : jhr 4002 Added support scripts for *Mac OS X PackageMaker* and modified
3042 :     +config/install.sh+ so that it supports re-dumping a heap image
3043 : jhr 3992 after customization.

3053 : jhr 3992
3054 :     //--------------------------------------------------------------------
3055 :     [2005/05/16]::
3056 :     +
3057 :     Added mechanism for re-creating a heap file for the interactive system
3058 :     after configuration variables have been changed.
3059 :     +
3060 : jhr 4002 [source,sml]
3061 :     ------------
3062 : jhr 3992 CM.redump_heap : string -> unit
3063 : jhr 4002 ------------
3064 : jhr 3992 +
3065 : jhr 4002 This is much like +SMLofNJ.exportML+, but starting from the resulting
3066 :     heap does not return to the caller of +CM.redump_heap+ but
3067 : jhr 3992 restarts the interactive system from scratch. The original call of
3068 : jhr 4002 +CM.redump_heap+ does not return but ends the interactive session.
3069 :     Thus, +CM.redump_heap+ is a lot like +SMLofNJ.exportFn+.
3070 : jhr 3992 +
3071 : jhr 4002 Internally, +redump_heap+ winds the dynamic execution context back to
3072 : jhr 3992 the point where the original heap image was created and re-executes
3073 :     the heap image generation code in the boot code.

3078 :     [2005/05/09]::
3079 :     +
3080 : jhr 4002 Added a hack to the existing hack known as +Word64+ to make +fromString+
3081 :     behave correctly. I am still not sure whether +Word64.scan+ will work
3082 : jhr 3992 as specified with respect to the interaction of radix and prefix.

3112 :     +
3113 :     Fixed serious bug (brown paper bag variety) in new implementation of
3114 : jhr 4002 structure +Atom+ in *CML*. (I had accidentally used a +mailbox+ instead of

3124 :     [2005/02/25]::
3125 :     +
3126 : jhr 4002 Brought back +SMLofNJ.Susp+. The underlying suspension type is the one

3148 :     //--------------------------------------------------------------------
3149 :     [2005/02/10]::
3150 :     +
3151 : jhr 4002 Implemented "+long long+" arguments and results for NLFFI. (Only the
3152 : jhr 3992 PPC/MacOS implementation is complete, the other backends still need to
3153 :     be updated.)

3158 :     [2005/01/24]::
3159 :     +
3160 :     Minor cleanup in ML-Yacc rule printing mechanism. This should fix a
3161 :     problem with certain "as" patterns which previously got rendered
3162 :     using incorrect syntax.

3165 : jhr 3992
3166 :     //--------------------------------------------------------------------
3167 :     [2005/01/18]::

3169 :     Made time profiling code (interrupt handler) in runtime system aware
3170 :     of new array representation.

3172 : jhr 3995 owner:[Matthias Blume,http://www.tti-c.org/blume/]
3173 : jhr 3992
3174 :     //--------------------------------------------------------------------
3175 :     [2005/01/14]::
3176 :     +
3177 : jhr 4002 Implemented new (but still experimental) *heap2exec* facility. This is
3178 : jhr 3992 tested under Mac OS X and should work under Linux (will test shortly).
3179 :     It will probably also work on the Sparc (will test some time later).
3180 : jhr 4002 Also removed old "+HACKED_STANDALONE+" hack from runtime
3181 : jhr 3992 +
3182 : jhr 4002 To be able to test *heap2exec*, uncomment the request for "+heap2asm+" in
3183 : jhr 3992 config/targets prior to installation. (Notice that this is different
3184 :     from "heap2exec" mentioned below. Not a typo.)
3185 :     +
3186 :     To perform an actual test, run the command
3187 :     +
3188 :     $ bin/heap2exec heapfile execfile
3189 :     +
3190 : jhr 4002 (You can put *heap2exec* on your shell's path.)
3191 : jhr 3992 +
3192 :     For example, run
3193 :     +
3194 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
3195 :     +
3196 : jhr 4002 This will create a standalone executable called "+mly+" that you can
3197 : jhr 3992 then invoke directly as a command.

3218 : jhr 4002 * Implemented access to signed and unsigned long long data in *NLFFI*.
3219 : jhr 3992 (The parameter-passing part of the picture has not complete. But
3220 :     data structure access seems to work.)
3221 :     +
3222 : jhr 4002 * Fixed *CM*'s incorrect assumption that the PPC is little-endian.
3223 : jhr 3992 (On the Mac, it is big-endian. And that's currently our only
3224 : jhr 4002 *PPC* platform.)

3231 : jhr 4002 Some cleanup in the +$c/memory.cm+ library: separated some concerns by

3239 :     +
3240 : jhr 4002 The Unix I/O library of SML/NJ on Cygwin does not understand
3241 : jhr 3992 Windows style pathname, so problems arise when +SMLNJ_HOME+ is set
3242 : jhr 4002 to a Windows style pathname. The _run-sml script now

3261 : jhr 4002 - +HashString.hashString' -> HashString.hashSubstring
3262 :     - corresponding changes in +atom.sml+

3282 :     Hacked some of the scripts (in particular: the installer) to cope with
3283 :     spaces in filenames a bit better. But beware: the current "solution"
3284 :     is likely still full of bugs and inherently incomplete. (We need to

3328 :     [2004/11/24]::
3329 :     +
3330 : jhr 4002 The compiler can now be compiled in a mode that makes structure +Position+
3331 :     equal to +Int64+. The default, however, is unchanged (+Position+ is +Int31+)
3332 : jhr 3992 for the time being.
3333 :     +
3334 :     To enable 64-bit positions, use the following procedure:

3348 :     +
3349 : jhr 3992 This is barely tested. The only test so far was a little SML program
3350 :     counting the number of characters in an 8-gigabyte file by
3351 :     reading it character-by-character. That test was successful.

3390 : jhr 3992 The date string is generated at bootstrap time (during makeml).
3391 :     +
3392 :     - In a previous commit, fixed a minor issue with how polyequal is being
3393 :     translated. In particular, the code now "looks through" abstractions.
3394 :     This results in slightly fewer polyEqual warnings and hopefully slightly
3395 :     more efficient code. Important examples for where this matters are

3424 : jhr 3995 Structure +Word64+ is now (almost) complete, word literals and patterns
3425 : jhr 3992 seem to work. There are a few odd pieces missing. In particular,
3426 : jhr 3995 I didn't do the {++from++,++to++}++LargeWord++ parts because +LargeWord+
3427 :     is still +Word32+ at the moment.
3428 : jhr 3992 +
3429 : jhr 3995 Making +Word64+ official would mean that +LargeWord+ becomes +Word64+. But
3430 : jhr 3992 this requires extreme care because most word-word conversions have to
3431 : jhr 3995 go through +LargeWord+, so making a mistake means loss of efficiency or
3432 : jhr 3992 worse. Eventually there will be a solution similar to (but actually

3507 :     Added a mechanism for getting back-trace information from standalone
3508 :     programs. Here is how it works:
3509 :     +
3510 : jhr 4002 --
3511 :     . The part of the program from which you want to get backtrace
3512 :     information (usually the whole program) should be wrapped with
3513 :     BackTrace.monitor. This is a +(unit->'a)->'a+ function, and your

3526 :     ------------
3527 : jhr 3992 +
3528 : jhr 4002 . To be able to access +BackTrace.monitor+, you have to add the
3529 :     library +$smlnj-tdp/plugins.cm+ to the +.cm+ file that contains your
3530 :     main function.
3531 : jhr 3992 +
3532 : jhr 4002 . Remove all compiled code (_i.e._, all the .cm/ subdirectories that

3753 : jhr 3995 [source,sml]
3754 :     ------------
3755 :     val save'restore: 'a control -> unit -> unit

3757 : jhr 3992 +

3765 : jhr 3992 +
3766 : jhr 3995 stores the given value into the control in stage 2 (_i.e._, delayed)
3767 :     but does all error checking in stage 1.
3768 :     (This is for string controls that need to do parse their argument --
3769 :     something that might fail. In some cases, notably in CM, one

3788 : jhr 3995 Added a new tool class called "+lazysml+" to CM's tool chest. The only

3792 : jhr 3992 +
3793 : jhr 3995 In addition to the above feature, the original class "+sml+" now also
3794 :     supports a tool argument "+lazy+" which has the same effect. As a

3802 : jhr 3992 +
3803 :     The setting goes into effect both during parsing and during
3804 :     compilation. The original setting is restored right after parsing and
3805 :     after compilation, respectively.
3806 :     +
3807 :     In addition to all the above, there is also a general mechanism to set
3808 :     ANY of the "controls" that are available at the command line via
3809 : jhr 3995 "+-C...+" on a per-sml-file basis. The same rules that apply for "+lazy+"

3813 : jhr 3995 The +.cm+ file syntax uses a new keyword tool argument called "+with+".
3814 : jhr 3992 There are several ways of indicating the desired settings:
3815 :     +
3816 : jhr 3995 ....................
3817 : jhr 3992 foo.sml (with:parser.quotations=true)
3818 :     foo.sml (with:(name:parser.quotations value:true))
3819 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
3820 :     foo.sml (with:(name1=value1 name2=value2 ...))
3821 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
3822 : jhr 3995 ....................
3823 : jhr 3992 +
3824 : jhr 3995 Another possible abbreviation is to leave out the +=v+ or +value:v+ part
3825 : jhr 3992 if the name refers to a boolean control (in which case the value is
3826 :     taken to be true). Thus, one could get lazy sml also by saying:

4173 :     +
4174 :     In the case of Unix there still seems to be an open/weird issue:
4175 :     +
4176 :     The {text,bin}{In,Out}streamOf functions are supposed to create
4177 :     fresh streams whenever they are called -- as opposed to have them
4178 :     return the same stream every time. This design is supposed to
4179 :     prevent space leaks caused by proc values hanging on to streams.
4180 :     +
4181 :     The reap function, on the other hand, is supposed to close the
4182 :     streams. This cannot be done without having a handle on the
4183 :     stream in proc after all...
4184 :     +
4185 :     I took the liberty to implement the following stopgap solution:
4186 :     +
4187 :     The proc value hangs on to the most recently created stream(s).
4188 :     Reap closes those. If either or both of the two streams hadn't
4189 :     been created at all yet, then reap will close the corresponding
4190 :     file descriptors directly.
4191 :     +
4192 :     PS: I don't understand the original space leak argument anymore. If
4193 :     a proc hangs on to the imperative stream, then I/O operations on those
4194 :     will advance the state of the cached stream and avoid the space leak.

4208 :     CM now ignores (but still accepts) the "owner" information in group
4209 :     descriptions. The owner of a group is its next enclosing
4210 :     library. Each group must have a unique owner. (There is a virtual
4211 :     "toplevel" library that owns groups which are not nested within a real
4212 :     library.) Previously, each group had to explicitly declare its owner,
4213 :     and CM would check that such a declaration is correct. The new scheme
4214 :     is to have CM check that for each group there is precisely one owning
4215 :     library.
4216 :     +
4217 :     The advantage of the new scheme is that the programmer no longer needs
4218 :     to maintain the somewhat annoying owner information. The downside is
4219 :     that CM cannot enforce the ownership rule across multiple runs of
4220 :     CM.make. Fortunately, enclosing the same group in two different
4221 :     libraries A and B which are not part of the same program does not
4222 :     cause real problems.

4227 :     [2004/05/20]::
4228 :     +
4229 :     Made the win32 version work again. (Strangely, a misplaced comma had
4230 :     slipped into win32-process.c which prevented the runtime from being
4231 :     compiled correctly.)
4232 :     +
4233 :     Also, included a minor addition to ml-build.bat analogous to what was
4234 :     done in blume-20040519-ml-build.
