1 : jhr 4603 = Standard ML of New Jersey Change Log
2 : jhr 3992 The Fellowship of SML/NJ
3 : jhr 4603 :revnumber: {version}
4 :     :revdate: {releasedate}
5 :     :source-highlighter: pygments
6 : jhr 3992
7 : jhr 4468 This file documents changes to the *Standard ML of New Jersey* system since
8 : jhr 4002 March of 2000 (around Version 110.26). The change log primarily covers
9 :     the compiler, the compilation manager (*CM*), the *MLRISC* library, and
10 :     the runtime system. There are occasional entries about other components
11 :     (_e.g._, the *SML/NJ Library* and *ML-LPT*), but these components have
12 :     their own change logs that should be consulted.
13 :    
14 : jhr 3992 //////////////////////////////////////////////////////////////////////
15 :     This change log is in ASCII doc format. An HTML version of the
16 :     change log can be generated using the command
17 :    
18 : jhr 4049 make html
19 : jhr 3992
20 :     An entry should be made for _every_ commit to the repository.
21 :     The entries in this file will be used when creating the README
22 :     for new versions, so keep that in mind when writing the
23 :     description.
24 :    
25 : jhr 4603 Also note that we now use Asciidoctor (asciidoctor.org) to process the
26 :     file, since the original Asciidoc is no longer under active development
27 :     and asciidoctor is also faster.
28 : jhr 3992 The structure of the HISTORY is that there is a section for
29 :     each release, which starts with a section header of the form
30 :    
31 :     == Version xxx.yy; yyyy/mm/dd
32 :    
33 :     The content of a section is a list of entries. The form of an
34 :     entry should be:
35 :    
36 :     [yyy/mm/dd]::
37 :     +
38 : jhr 3995 Description ...
39 : jhr 3992 +
40 : jhr 4603 owner:URL[Your Name]
41 : jhr 3992
42 : jhr 3995 Note that we put "+" at the beginning of blank lines. Entries are items
43 :     in a labeled list and the "+" character keeps eveything in the same list
44 :     element.
45 :    
46 : jhr 3992 Here is a quick asciidoc cheat sheet:
47 :    
48 :     + new paragraph
49 :     *foo* bold "foo"
50 :     _foo_ italic "foo"
51 : jhr 4603 `foo` teletype "foo"
52 : jhr 3992 http:/some.website.org/path[] URL
53 : jhr 4603 bugref:123[] displays as "#123" with
54 : jhr 3992 a link to the bug report.
55 : jhr 4603 bugref:123[feature] displays as "#123" with a
56 : jhr 4134 link to the feature request.
57 : jhr 4603 owner:url[name] displays name with URL link.
58 : jhr 3992
59 : jhr 3995 Sub lists should be bracketed with lines containing just "--".
60 : jhr 3992 Bulleted list items start with a single dash or one to five
61 : dbm 4298 asterisks followed by some white space then some text. Numbered
62 : jhr 3992 list items begin one to five period characters, followed by
63 :     some white space then the item text.
64 :    
65 : jhr 3995 Literal (verbatim) blocks are delimited by
66 :     .....................
67 :     stuff
68 :     .....................
69 :    
70 : jhr 3992 Superscripts and subscripts are denoted by putting ^ (or ~)
71 :     around the text to superscripted (superscripted). For example,
72 :     the number 256 can be written as 2^8^.
73 :    
74 :     SML source code displays can be included as source blocks:
75 :    
76 :     [source,sml]
77 :     ------------
78 :     structure Foo = struct val x = 1 end
79 :     ------------
80 :    
81 : jhr 4603 To process the file, you will need asciidoctor and the pygments.rb gem
82 :     installed. See the Asciidoctor manual at https://asciidoctor.org/docs/user-manual
83 :     for more information.
84 : jhr 3992
85 : jhr 4002 NOTE: the original HISTORY file was converted to ASCIIDOC using a Perl
86 :     script. This script gets the basic structure for entries correct,
87 :     but there still needs to be a fair bit of editing to add ASCIIDOC
88 :     markup, fix indentation issues, nested lists, etc. Working from most
89 :     recent to oldest, I've edited back to release 110.46 (2004/06/17).

95 : jhr 4220
96 : jhr 4672 //--------------------------------------------------------------------
97 :     [2018/06/15]::
98 :     +
99 :     Fixed a compiler bug (`arg ty lists wrong length`) in `unifyTy` that
100 :     could occur when one of the type constructors is the `ERRORtyc`.
101 :     This occurs because the `ERRORtyc` is equal to any other type
102 :     constructor, which (incorrectly) implies that the number of type
103 :     arguments should be equal.

111 : jhr 4624 [2018/05/29]::
112 :     +
113 : jhr 4639 Fixed bugref:206[] (Parsing of explicit type variables and val rec
114 :     is broken). This bug was also bug number 1261 in the old bugs list.
115 : jhr 4624 +
116 :     owner:cs.uchicago.edu/~jhr[John Reppy]

119 : dbm 4628 [2018/05/29]::
120 :     +
121 : jhr 4639 Fixed minor bug in Date.toString (missing leading "0" for day of month).
122 :     This issue was bug number 1444 in the old bugs list.

125 :    
126 :     //--------------------------------------------------------------------
127 :     [2018/05/29]::
128 :     +
129 :     Cleaned up match compiler code (`FLINT/trans/matchcomp.sml`) and added
130 :     typing and function comments. Added debugging and printing
131 :     infrastructure, including new `FLINT/trans/mcprint.sml` file, and new
132 :     `Control.MC.debugging` flag.

143 :     //--------------------------------------------------------------------
144 : jhr 4619 [2018/05/28]::

146 :     Fixed the scanner to produce the correct error message for bad escape
147 :     sequences in string literals.

152 : jhr 4614 [2018/05/26]::
153 :     +
154 : jhr 4639 Fixed old bug number 1383: `Char.toCString #"\000"` returned `"\\0"`,
155 : jhr 4619 instead of `"\\000"`, which caused `String.toCString` to produce invalid
156 :     results.

169 :     +
170 :     Added `MONO_BUFFER` signature, with instances `CharBuffer` and `Word8Buffer`,
171 :     to Basis implementation
172 :     (https://github.com/SMLFamily/BasisLibrary/wiki/2018-001-Addition-of-monomorphic-buffers[

178 : jhr 4601 [2018/05/16]::
179 :     +
180 : jhr 4603 Fix a bug where "`0w`" was being accepted as a prefix for a hexidecimal
181 :     word value in `Word.fromString`/`scan` (ignoring case, only "`0x`"
182 :     and "`0wx`" are valid prefixes). This change fixes bug number 1375

188 : jhr 4596 [2018/05/13]::
189 :     +
190 :     Fixed a bug in the parsing of bindings involving the `op` keyword.
191 :     The parser was more restrictive than the definition. This change
192 : jhr 4639 fixes bug number 1370 from the old bugs list.

197 : jhr 4585 [2018/05/12]::
198 :     +
199 : jhr 4603 The lexer gave an unmatched close comment error on "`*)`", when it
200 : jhr 4639 should have scanned it as the tokens "`*`" "`)`". This change
201 :     fixes bug number 330 in the old bugs list.
202 : jhr 4585 +
203 :     **Note**: there is some ambiguity as to what the correct behavior
204 : jhr 4639 should be here. The __Definition of Standard ML__ (1997) only says that
205 : jhr 4585 unmatched __open__ comments should be signalled as errors, but the
206 : jhr 4639 __Commentary on the Definition of Standard ML__ (1991) says otherwise in
207 : jhr 4585 Appendix D. **SML/NJ** started signalling an error in version 0.71,
208 : jhr 4607 but we choose to revert to accepting this sequence, to match
209 :     the 1997 Definition (and the behavior of other systems).

224 : jhr 4572 Fixed various minor parsing and scanning issues:
225 :     +
226 :     --
227 :     * correct syntax for type variables
228 :     * signature/structure/functor IDs should always be alpha IDs
229 : jhr 4596 * the equality ID (`=`) cannot appear in a binding context. Note that
230 :     we still allow the syntax `val op = = ...` because it is needed to
231 :     parse the file `system/smlnj/init/built-in.sml`.

237 : jhr 4562 [2018/05/05]::
238 :     +
239 :     Completed overhaul of the way that int/word literals are handled in
240 :     the compiler. We now use `IntInf.int` to represent the values in
241 :     all IRs. This change also results in better CPS contraction, since
242 :     we now perform constant folding for both signed and unsigned values
243 :     at all sizes. We were also able to get rid of the tricky code that
244 :     worries about large tagged integer values that might cause overflow
245 :     during code generation.

252 :     Improved the reporting of errors involving literal values. We now
253 :     use the original source text when describing the value in the error
254 :     message.

259 : jhr 4533 [2018/04/20]::
260 :     +
261 : jhr 4603 Fix for bug bugref:191[] (Compiler crash when handling large reals).
262 : jhr 4533 We now issue a warning for real literals that will round to zero and
263 :     an error for real literals that are too large to represent. There
264 :     still needs to be done some work to support sub-normal literal values
265 :     (these are currently rounded to zero).

277 : jhr 4524 [2018/04/13]::
278 :     +
279 :     Removed real patterns from Absyn and FLINT, since they are not allowed
280 :     by SML'93 and were not present in the AST representation.

285 : jhr 4521 [2018/04/12]::
286 :     +
287 : jhr 4603 Fix for bug bugref:194[] (`Real.fromString` overflows or hangs). There
288 :     were two issues here. First, the `Overflow` exception was being raised
289 : jhr 4521 when scanning large exponents, but it was not being handled by the
290 : jhr 4596 scanning code. The second issue was that the scaling loop for large
291 :     exponents did not immediately terminate once infinity (or zero) was
292 :     reached, so it could take a long time.

299 :     Moved the check for whether a int or word literal is in range for

307 :     +
308 :     Part 1 of an overhaul of the way that the compiler treats int/word
309 : jhr 4603 literals. The end goal is to use `IntInf.int` to represent literals
310 : jhr 4501 throughout all phases of the compiler. In this step, we changed the
311 : jhr 4603 representation of literals in the `Absyn` representation (earlier
312 : jhr 4501 representations already used IntInf.int).

322 : jhr 4603 Fixed unnumbered bug in `IntInf.mod` and `IntInf.rem` functions,

330 :     +
331 : jhr 4468 Various bits of cleanup in the handling of primitive operations, such
332 : jhr 4603 as removing the `ptnum` mechanism for translating from Absyn to FLINT.

337 :     [2017/09/20]::
338 :     +
339 : jhr 4603 Added `Target` module, which specifies the properties of the target
340 : jhr 4467 (__e.g.__, the size in bits of the default int type). Reworked the
341 : jhr 4603 generation of the `InlineT` structure to be target specific.

347 :     +
348 : jhr 4420 Removed FLINT primops (and their CPS counterparts) that are not

356 : jhr 4603 Fixed bug bugref:123[] (missing nonexhaustive bind warning). The `mkVBs`
357 :     function in `FLINT/trans/translate.sml` was adding a redundant default

365 :     +
366 : jhr 4603 Fixed bug bugref:183[] (status code returned by sml REPL). This fix
367 :     restores the version 110.79 behavior of having `sml foo.sml` exit with
368 :     a non-zero status when there is a type-checking error in `foo.sml`.
369 :     It also cleans up the error messages associated with `use` when there

377 : jhr 4603 Fixed bug bugref:185[] (Bring command line help text into parity with man page).
378 :     Added missing options (`@SMLversion` and `@SMLsuffix`) to the
379 :     help message that is printed for the command "`sml -h`". Also
380 : jhr 4399 adjusted the order of options in the help message, and in the man

386 : jhr 4375 [2017/08/12]::
387 :     +
388 :     Changed the way that we test for allocation-space addresses in minor GCs.
389 :     Instead of using the BIBOP, we now do a pointer range test. On 32-bit
390 :     systems, this change results in a small (~0.13%) performance boost, but
391 :     we expect a bigger impact on 64-bit hardware, where the cost of BIBOP
392 :     probes will be higher and there are more registers available to hold
393 :     the nursery bounds.

400 :     Fixed some issues in build-literals.c. These were mostly false
401 :     positives in the assertions, but there was also a bug in the way
402 :     that the available space was tracked that could conceivably
403 :     result in a crash (but was very unlikely).

2055 : jhr 3992 +
2056 : jhr 4603 Also, changed the handling of "no core access": When `translate.sml`
2057 : jhr 3992 needs access to a core exception at a time when the core has not
2058 : jhr 4603 been set up yet (this only happens when compiling `system/smlnj/init/`*),
2059 : jhr 3992 then don't bother generating the corresponding tests.
2060 :     +
2061 :     The old scheme was to generate a bogus value to be used in place of
2062 :     the exception. Unfortunately, that confuses the plambda type checker.
2063 :     Moreover, it does not do any good, because at runtime we don't expect
2064 : jhr 4603 such an exception to be ever raised. (The code in `system/smlnj/init/`*
2065 : jhr 3992 has to be written very carefully with this in mind!)

2108 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
2109 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
2110 :     +
2111 : jhr 4603 (In addition, CMB_REBUILD_MODE is defined for `makeml -rebuild`,
2112 : jhr 3992 CM_SLAVE_MODE is defined in attached slaves while running CM.make
2113 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
2114 : jhr 4603 while running `CMB.make`. The point is that the single symbol
2115 : jhr 3992 NO_PLUGINS is definde in all three cases.)
2116 :     +
2117 :     I changed the three locations within the sources that get compiled
2118 : jhr 4603 during `CMB.make` where *ml-yacc* or *ml-lex* input is processed: When
2119 : jhr 3992 NO_PLUGINS defined, then the use of the mlyacc and mllex tools
2120 :     is bypassed.
2121 :     +
2122 :     When bootstrapping new versions of the compiler, there can be
2123 :     situations where the plugin tools for *ml-yacc* and *ml-lex* (or *ml-ulex*)
2124 :     are not available or otherwise not operational. In this case one can
2125 : jhr 4603 manually define the NO_PLUGINS symbol prior to running `CMB.make()`. To
2126 : jhr 3992 do so, the following command should be issued at the interactive

2134 : jhr 4603 A `CMB.make` with NO_PLUGINS defined relies on the existence of the

2157 :     +
2158 :     There are now a number of new installation targets that give some

2174 :     CM fail if a shell tool reports a non-success exit status. If

2195 : jhr 3992 |===============================================
2196 :     +
2197 :     The *ml-antlr* specification format has changed: declarations such as
2198 : jhr 4603 `%tokens` and nonterminal definitions can occur *multiple* times in the
2199 : jhr 3992 same specification. The semantics are such that each new declaration
2200 : jhr 4603 extends the previous ones. This does not apply to `%start` or `%name`,
2201 : jhr 3992 of course.
2202 :     +
2203 : jhr 4603 Importing a grammar via `%import` now includes *all* declarations in from
2204 :     the imported grammar, except for `%name`, `%entry`, and `%start`. Tokens
2205 :     and nonterminals can be dropped using the new `%dropping` clause of the
2206 :     `%import` directive; the separate `%drop` and `%extend` have been removed.
2207 : jhr 3992 +
2208 : jhr 4603 We now allow optional type annotations on nonterminals, using the `%nonterms`
2209 : jhr 3992 directive as in *ml-yacc*.
2210 :     +
2211 : jhr 4603 The `refcell` construct is now implemented using SML's regular reference
2212 :     cells, so the `:==` and `!!` notation has been deprecated.
2213 : jhr 3992 +
2214 : jhr 4216 The *ml-antlr* tool now does much more checking of specifications, and
2215 : jhr 3992 its error messages have been greatly improved. Error repair for
2216 :     generated parsers has been completely rewritten, and is now both
2217 :     much faster and more accurate.
2218 :     +
2219 :     *ml-ulex* is now more lenient with escape codes (non-SML-standard
2220 : jhr 4603 escape codes are now interpreted literally, so _e.g._, `\|` denotes "`|`").
2221 :     Also, character classes may now include a "`-`" character at the beginning
2222 : jhr 3992 as is standard in most other regexp tools.
2223 :     +
2224 : jhr 4216 All of these changes are documented in the user guide, which has

2408 :     //--------------------------------------------------------------------
2409 :     [2007/01/31]::
2410 :     +
2411 : jhr 4216 Brought ml-lpt manual up-to-date with the code. Many minor
2412 : jhr 3992 improvements to the tools, and a few minor bugfixes. Prepared
2413 : jhr 4603 ml-lpt-lib for integration with new `UTF8` structure. Changed
2414 : jhr 3992 the interface for creating streams in *ml-ulex* (we now support
2415 : jhr 4216 stream creation from several kinds of sources). Overall, the
2416 :     tools are now quite stable, and their interfaces are unlikely to
2417 : jhr 3992 change in a way that would break compatibility. More work,
2418 :     however, is needed in the documentation.

2422 :     //--------------------------------------------------------------------
2423 :     [2007/02/01]::
2424 :     +
2425 :     Implemented library installer. Moved CM plugin code for
2426 :     *ml-burg*, *ml-lex*, and *ml-yacc* out of CM source tree and into
2427 :     their respective trees. Implemented CM plugin for *ml-ulex*
2428 :     and *ml-antlr*. Used library installer for *ml-burg*, *ml-ulex*,
2429 :     and *ml-antlr*.
2430 :     +
2431 :     For *ml-yacc* and *ml-lex* we continue to have permanently "plugged-in"
2432 :     CM tools. (It turns out to be too messy to do otherwise because
2433 :     there is too much code that during installation relies on the presence
2434 :     of these tools -- resulting in a tricky ordering problem.)

2438 :     //--------------------------------------------------------------------
2439 :     [2007/01/30]::
2440 :     +
2441 : jhr 4603 Added `SMLofNJ.shiftArgs` which is like a shell's "shift" command.
2442 :     Modified CM's startup code to use `shiftArgs` as it processes
2443 : jhr 3992 command line arguments. This way, the init code in each .sml-file
2444 :     or library that is mentioned at the top level will see only
2445 :     those arguments that have not yet been processed at this point.
2446 :     In other words, the init code can "seize control" and process the
2447 :     remaining command line.

2462 : jhr 4603 Added the `UTF8` structure and signature from the Moby compiler to

2496 : jhr 4603 Fixed the code in `runtime/c-libs/posix-tty/`{`tcgetattr`,`tcsetattr`}`.c` to
2497 : jhr 3992 get the c_cc termios data copied correctly. Also moved the allocation

2504 :     //--------------------------------------------------------------------
2505 :     [2006/12/08]::
2506 :     +
2507 :     Added code to CM's "standard shell tool" implementation which
2508 :     causes it to tolerate (with a warning) the situation where the shell
2509 :     command fails (_e.g._, due to the shell command's non-existence)
2510 :     as long as all target files exist.
2511 :     +
2512 :     This makes it possible to, _e.g._, build *ml-yacc* from sources even if
2513 :     svn checkout messed up the time stamps on files in such a way that
2514 : jhr 4603 `yacc.grm` is younger than yacc.grm.sml or `yacc.grm.sig`. (*Ml-yacc*
2515 :     would be needed to re-process `yacc.grm`, but obviously it might not yet be
2516 : jhr 3992 available at that time.)

2598 :     In addition, there is also a new
2599 :     +
2600 :     ...........
2601 :     ml-lpt
2602 :     ...........
2603 :     +
2604 :     directory containing two new program generator tools: *ml-ulex* and
2605 :     *ml-antlr* (a lexer generator that handles unicode and an ANTRL-inspired
2606 :     LL(k) parser generator). These tools are currently "beta-quality"
2607 :     +
2608 :     The latest versios of the sources can now be obtained anonymously
2609 :     via subversion. For this, it is useful to first check out
2610 :     +
2611 :     ...........
2612 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
2613 :     ...........
2614 :     +
2615 :     and put the resulting directory on your shell's PATH. This provides
2616 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
2617 :     and refresh-all.sh.
2618 :     +
2619 :     To create a freshly checked-out copy of the sources, do
2620 :     +
2621 :     ...........
2622 :     checkout-all.sh [dir]
2623 :     ...........
2624 :     +
2625 :     where dir is the optional SML/NJ root directory (default is ".").
2626 :     +
2627 :     This creates the above directory layout. Each subdirectory of
2628 :     the root is under individual subversion control. The stat-all.sh
2629 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
2630 :     each of these subtrees.

2634 :     //--------------------------------------------------------------------
2635 :     [2006/11/02]::
2636 :     +
2637 :     Reorganized directory layout.
2638 :     +
2639 :     This is a temporary solution, more reorganization is to come.
2640 :     +
2641 :     The basic idea is to have a number of toplevel trees, each corresponding
2642 :     to a well-defined part of the overall system. Each part can be
2643 :     maintained individually, even in separate source repositories,
2644 :     although currently we still serve everything out of the main
2645 :     smlnj-gforge tree.
2646 :     +
2647 :     Installer and and scripts have been updated to reflect the new
2648 :     layout. The installer (base/src/system/smlnj/installer) is now
2649 :     "scriptable" to avoid burning too much knowledge about the
2650 :     layout into SML source code. The main script used by the installer
2651 :     is in config/actions.
2652 :     +
2653 :     The main change is that many of the subdirectories of what used to
2654 :     be known as "src" have moved to the toplevel. The "src" directory
2655 :     itself has moved down into a subtree called "base". (We may eventually
2656 :     get rid of the extra level of indirection represented by "src".)
2657 :     +
2658 :     The layout is now as follows:
2659 :     +
2660 : jhr 4002 [frame="none",width="90%",cols="<2,<3",options="header"]

2695 :     +
2696 : jhr 4603 `admin/refresh-all.sh` [__dir__]::
2697 : jhr 4002 looks at all trees (from the above list) in _dir_ (default: .)

2795 :     [2006/03/01]::
2796 :     +
2797 : jhr 4002 Incorporated several bugfixes to *lexgen*. Compiler now compiles to
2798 : jhr 3992 fixpoint when using lexgen instead of *ml-lex*.

2804 :     +
2805 : jhr 4002 Removed *ml-flex* and added *lexgen* instead, using Aaron Turon's newly

2826 :     //--------------------------------------------------------------------
2827 :     [2006/02/23]::
2828 :     +
2829 : jhr 4002 Changes to support building on *x86-64* systems (using the 32-bit mode).
2830 :     Also cleaned up signal handling on *Linux*. Support for pre-2.2 *Linux*
2831 : jhr 3992 kernels dropped.

2843 :     //--------------------------------------------------------------------
2844 :     [2006/02/14]::
2845 :     +
2846 :     Hooked code for Darwin-specific Intel ABI into main compiler.
2847 :     (This is a temporary solution which relies on the fact that the
2848 :     compiler itself does not use NLFFI. Eventually we need to divorce
2849 :     intel mac from generic x86 unix code and make separate sets of binaries.)

2861 :     [2006/02/06]::
2862 :     +
2863 : jhr 4002 Changes to support *Mac OS X* on Intel hardware. The C-calls support in
2864 :     MLRISC must also be updated to support the *Mac OS X* ABI.

2874 : jhr 3992
2875 :     //--------------------------------------------------------------------
2876 :     [2005/11/21]::
2877 :     +
2878 : jhr 4603 Enabling `$/html-lib.cm` in `config/preloads` did not work. This is fixed
2879 :     now. (Since the anchor mapping for `html-lib.cm` is not yet in effect
2880 :     at the time when `config/preloads` is processed, the library has to
2881 : jhr 3992 be referred to by another name. In 110.57 this would be
2882 : jhr 4603 `$SMLNJ-LIB/HTML/html-lib.cm`. I arranged for `$smlnj/smlnj-lib/html-lib.cm`
2883 : jhr 3992 to be valid as well.)
2884 :     +
2885 :     Thanks to Todd Wilson (Fresno) for alerting me to this issue.

2893 :     //--------------------------------------------------------------------
2894 :     [2005/11/19]::
2895 :     +
2896 : jhr 4603 Fixed a problem in `config/install.sh` where it tries to "fish" the
2897 : jhr 4002 name of the *CM* metadata directory from the wrong place (because
2898 : jhr 4603 the physical location of `basis.cm` has changed). Also, corrected the
2899 :     path anchor for `$/html-lib.cm`. (Thanks to M. Fluet for pointing out
2900 : jhr 3992 these problems.)

2908 :     //--------------------------------------------------------------------
2909 :     [2005/11/16]::
2910 :     +
2911 :     Fixed problem with bogus exception message when using back-trace
2912 :     facility.

2915 : jhr 3992
2916 :     //--------------------------------------------------------------------
2917 :     [2005/11/15]::
2918 :     +
2919 : jhr 4603 Added simple implementation of `Array2.copy`. (Warning: mostly untested.)

2922 : jhr 3992
2923 :     //--------------------------------------------------------------------
2924 :     [2005/11/15]::
2925 :     +
2926 : jhr 4603 Reversed change to `src/system/smlnj/internals/versiontool.cm`. This
2927 : jhr 3992 file gets loaded as a tool -- by the equivalent of CM.make during the
2928 : jhr 4603 run of `CMB.make`. Thus, CMB's path configuration is meaningless for
2929 : jhr 3992 it. Instead, it has the status of "user code", so it should use
2930 : jhr 4603 `$/basis.cm` to refer to the Basis library. (At least that's true for
2931 : jhr 3992 the purpose of bootstrapping the previous change. In the future it
2932 : jhr 4603 might make sense to have `versiontool.cm` refer to
2933 :     `$smlnj/basis/basis.cm`, _i.e._, the version of the Basis that the
2934 : jhr 3992 compiler itself uses.)
2935 :     +
2936 : jhr 4603 Also patched `src/system/testml` to have it activate those extra anchor
2937 :     bindings in `config/extrapathconfig`.
2938 : jhr 3992 +
2939 : jhr 4603 owner:www.tti-c.org/blume/[Matthias Blume]
2940 : jhr 3992
2941 :     //--------------------------------------------------------------------
2942 :     [2005/11/15]::
2943 :     +
2944 :     This change affects the way the following libraries are tied into
2945 :     the system:
2946 :     +
2947 : jhr 4002 ....................
2948 : jhr 3992 $/basis.cm
2949 :     $/smlnj-lib.cm
2950 :     $/pp-lib.cm
2951 :     $/controls-lib.cm
2952 :     $/html-lib.cm
2953 :     $/ml-yacc-lib.cm
2954 : jhr 4002 ....................
2955 : jhr 3992 +
2956 :     These libraries are now internally (as seen from the source code
2957 :     of the implementation itself) known by the following names:
2958 :     +
2959 : jhr 4002 ....................
2960 : jhr 3992 $smlnj/basis/basis.cm
2961 :     $smlnj/smlnj-lib/smlnj-lib.cm
2962 :     $smlnj/smlnj-lib/pp-lib.cm
2963 :     $smlnj/smlnj-lib/controls-lib.cm
2964 :     $smlnj/smlnj-lib/html-lib.cm
2965 :     $smlnj/ml-yacc/ml-yacc-lib.cm
2966 : jhr 4002 ....................
2967 : jhr 3992 +
2968 :     This makes it possible to work with code that requires different
2969 :     versions of these libraries, and which refers to these libraries using
2970 :     their "default" names (_i.e._, the first set of names above). In other
2971 :     words, one can un-define or re-define those default names without
2972 :     compromising the proper functioning of the compiler itself.
2973 :     +
2974 :     A similar procedure had already been performed for several of the
2975 : jhr 4002 *MLRISC* libraries that are linked into the compiler. I did some
2976 : jhr 3992 cleanup on this code.
2977 :     +
2978 :     A new file in the config directory (named extrapathconfig) is
2979 :     responsible for setting up path anchors that the compiler itself does
2980 :     not need, but that are typically required by user code.

3154 : jhr 3992 CM.redump_heap : string -> unit
3155 : jhr 4002 ------------
3156 : jhr 3992 +
3157 : jhr 4603 This is much like `SMLofNJ.exportML`, but starting from the resulting
3158 :     heap does not return to the caller of `CM.redump_heap` but
3159 : jhr 3992 restarts the interactive system from scratch. The original call of
3160 : jhr 4603 `CM.redump_heap` does not return but ends the interactive session.
3161 :     Thus, `CM.redump_heap` is a lot like `SMLofNJ.exportFn`.
3162 : jhr 3992 +
3163 : jhr 4603 Internally, `redump_heap` winds the dynamic execution context back to
3164 : jhr 3992 the point where the original heap image was created and re-executes
3165 :     the heap image generation code in the boot code.

3205 :     Fixed serious bug (brown paper bag variety) in new implementation of
3206 : jhr 4603 structure `Atom` in *CML*. (I had accidentally used a `mailbox` instead of
3207 :     an `mvar`, leaving the door open for races.)

3218 : jhr 4603 Brought back `SMLofNJ.Susp`. The underlying suspension type is the one

3267 :     [2005/01/14]::
3268 :     +
3269 : jhr 4002 Implemented new (but still experimental) *heap2exec* facility. This is
3270 : jhr 3992 tested under Mac OS X and should work under Linux (will test shortly).
3271 :     It will probably also work on the Sparc (will test some time later).
3272 : jhr 4603 Also removed old "`HACKED_STANDALONE`" hack from runtime
3273 : jhr 3992 +
3274 : jhr 4603 To be able to test *heap2exec*, uncomment the request for "`heap2asm`" in
3275 : jhr 3992 config/targets prior to installation. (Notice that this is different
3276 :     from "heap2exec" mentioned below. Not a typo.)
3277 :     +
3278 :     To perform an actual test, run the command
3279 :     +
3280 :     $ bin/heap2exec heapfile execfile
3281 :     +
3282 : jhr 4002 (You can put *heap2exec* on your shell's path.)
3283 : jhr 3992 +
3284 :     For example, run
3285 :     +
3286 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
3287 :     +
3288 : jhr 4603 This will create a standalone executable called "`mly`" that you can

3312 :     data structure access seems to work.)
3313 :     +
3314 : jhr 4002 * Fixed *CM*'s incorrect assumption that the PPC is little-endian.
3315 : jhr 3992 (On the Mac, it is big-endian. And that's currently our only

3374 :     Hacked some of the scripts (in particular: the installer) to cope with
3375 :     spaces in filenames a bit better. But beware: the current "solution"
3376 :     is likely still full of bugs and inherently incomplete. (We need to

3413 :     [2004/11/24]::

3415 : jhr 4603 Made sure *CML* compiles when the `Position` structure is `Int64`.

3418 : jhr 3992
3419 :     //--------------------------------------------------------------------
3420 :     [2004/11/24]::
3421 :     +
3422 : jhr 4603 The compiler can now be compiled in a mode that makes structure `Position`
3423 :     equal to `Int64`. The default, however, is unchanged (`Position` is `Int31`)
3424 : jhr 3992 for the time being.

3428 : jhr 4002 --
3429 :     . Start sml
3430 :     . Autoload $smlnj/cmb.cm (if not already autoloaded)

3436 :     ------------
3437 :     +

3439 : jhr 4002 --
3440 :     +
3441 : jhr 3992 This is barely tested. The only test so far was a little SML program
3442 :     counting the number of characters in an 8-gigabyte file by
3443 :     reading it character-by-character. That test was successful.
3444 :     +
3445 :     In support of 64-bit positions, a number of new functions have been
3446 :     added to the runtime system.

3481 : jhr 4603 - Stripped down the `versiontool:` It now only handles the version number.
3482 : jhr 3992 The date string is generated at bootstrap time (during makeml).
3483 :     +
3484 :     - In a previous commit, fixed a minor issue with how polyequal is being
3485 :     translated. In particular, the code now "looks through" abstractions.
3486 :     This results in slightly fewer polyEqual warnings and hopefully slightly
3487 :     more efficient code. Important examples for where this matters are
3488 : jhr 4603 the new `int64` and `word64` types.

3495 : jhr 4603 Structure `Int64` fully hooked in. (The implementation is not very

3501 :     [2004/11/11]::
3502 :     +
3503 : jhr 4603 All the pieces of `Word64` are now there, with the exception of the
3504 :     conversions from and to `LargeWord`. (Eventually these need to be identities,
3505 :     but for the time being they don't even make sense because `LargeWord` is
3506 : jhr 3992 32-bit wide.)
3507 :     +
3508 : jhr 4603 Also started to add similar support for `Int64`, but major pieces of that
3509 : jhr 3992 are still missing.

3513 :     //--------------------------------------------------------------------
3514 :     [2004/11/11]::
3515 :     +
3516 : jhr 4603 Structure `Word64` is now (almost) complete, word literals and patterns
3517 : jhr 3992 seem to work. There are a few odd pieces missing. In particular,
3518 : jhr 4603 I didn't do the {`from`,`to`}`LargeWord` parts because `LargeWord`
3519 :     is still `Word32` at the moment.
3520 : jhr 3992 +
3521 : jhr 4603 Making `Word64` official would mean that `LargeWord` becomes `Word64`. But
3522 : jhr 3992 this requires extreme care because most word-word conversions have to
3523 : jhr 4603 go through `LargeWord`, so making a mistake means loss of efficiency or
3524 : jhr 3992 worse. Eventually there will be a solution similar to (but actually
3525 : jhr 4603 simpler than) what I did with `IntInf`.

3597 :     [2004/10/20]::
3598 :     +
3599 :     Added a mechanism for getting back-trace information from standalone
3600 :     programs. Here is how it works:
3601 :     +
3602 : jhr 4002 --
3603 :     . The part of the program from which you want to get backtrace
3604 :     information (usually the whole program) should be wrapped with
3605 : jhr 4603 BackTrace.monitor. This is a `(unit->'a)->'a` function, and your
3606 : jhr 4002 main program could be modified from something like
3607 : jhr 3992 +
3608 : jhr 4002 [source,sml]
3609 :     ------------
3610 :     fun main (pgm, args) = ...
3611 :     ------------
3612 : jhr 3992 +
3613 : jhr 4002 to
3614 : jhr 3992 +
3615 : jhr 4002 [source,sml]
3616 :     ------------
3617 :     fun main (pgm, args) = BackTrace.monitor (fn () => ...)
3618 :     ------------
3619 : jhr 3992 +
3620 : jhr 4603 . To be able to access `BackTrace.monitor`, you have to add the
3621 :     library `$smlnj-tdp/plugins.cm` to the `.cm` file that contains your
3622 : jhr 4002 main function.
3623 : jhr 3992 +
3624 : jhr 4002 . Remove all compiled code (_i.e._, all the .cm/ subdirectories that
3625 :     *CM* might have created in the past for your project).
3626 : jhr 3992 +
3627 : jhr 4002 . Build the system using this command line:
3628 : jhr 3992 +
3629 : jhr 4002 [source,sh]
3630 :     ------------
3631 :     ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm myprog.cm MyProg.main myprog
3632 :     ------------
3633 : jhr 3992 +
3634 : jhr 4002 instead of the usual
3635 : jhr 3992 +
3636 : jhr 4002 [source,sh]
3637 :     ------------
3638 :     ml-build myprog.cm MyProg.main myprog
3639 :     ------------
3640 :     --
3641 : jhr 3992 +
3642 : jhr 4603 I changed the library name `$/trace-debug-profile.cm` to `$smlnj-tdp/plugins.cm`,
3643 : jhr 4002 and added the following new libraries:
3644 : jhr 3992 +
3645 : jhr 4002 --
3646 : jhr 4603 `$smlnj-tdp/back-trace.cm`::
3647 : jhr 3992 +
3648 : jhr 4002 when loaded causes the back-trace plugin to be installed
3649 : jhr 3992 +
3650 : jhr 4603 `$smlnj-tdp/coverage.cm`::
3651 : jhr 3992 +
3652 : jhr 4002 when loaded causes the coverage plugin to be installed

3658 :     [2004/10/18]::
3659 :     +
3660 : jhr 4002 Added an "obsolete" warning for the "group owner" syntax to *CM*'s parser.
3661 : jhr 3992 +
3662 : jhr 4603 Eliminated group owner specs from `.cm` files throughout the source tree.

3667 :     [2004/10/15]::
3668 :     +
3669 : jhr 4002 --
3670 : jhr 3992 * Test coverage tool added!
3671 :     * Further reorganization of tracing-, debugging-, and profiling support:
3672 :     +
3673 :     - moved original BTImp -- now called BackTrace -- into a separate
3674 :     library called $/trace-debug-profile.cm
3675 :     - eliminated all mentions of BTrace from SMLofNJ.Internals
3676 :     - only the instrumentation mechanism is now left in the compiler proper
3677 :     - BackTrace module is a plugin which is NOT plugged in by default
3678 :     - Coverage module is another such plugin
3679 : jhr 4002 --
3680 : jhr 3992 +
3681 :     To get the benefits of any of these plugin modules, the code in
3682 : jhr 4002 question must be compiled with TDP instrumentation turned on. This
3683 : jhr 4603 can be done by setting `SMLofNJ.Internals.TDP.mode` to `true`.
3684 :     (The ref cell is also controlled via the `-Ctdp.instrument=...` switch.)
3685 : jhr 3992 +
3686 :     Plugins are selected at link time. (Pre-compiled instrumented code
3687 :     can be re-loaded with different plugins in effect.) When an
3688 :     instrumented module is linked, whatever plugins are at that time
3689 :     enabled will come into effect for that module.
3690 :     +
3691 : jhr 4603 To enable the back-trace plugin, load library `$/trace-debug-profile.cm`
3692 :     and invoke `BackTrace.install()` (_e.g._, from the interactive prompt).
3693 : jhr 3992 To enable the coverage plugin, load the same library and invoke
3694 : jhr 4603 `Coverage.install()`.
3695 : jhr 3992 +
3696 :     Back-traces are generated automatically on uncaught exceptions and
3697 : jhr 4603 when the code in question explicitly invokes `BackTrace.trigger()`.
3698 : jhr 3992 +
3699 :     Coverage (and execution frequency-) information must be queried
3700 : jhr 4603 explicitly by calling `Coverage.not_covered` and `Coverage.hot_spots`.

3705 :     [2004/10/14]::
3706 :     +
3707 : jhr 4603 Snapshot of a significant overhaul of how the `trace/debug/profile` support

3712 :     //--------------------------------------------------------------------
3713 :     [2004/10/13]::
3714 :     +
3715 :     Some rationalization of names:
3716 :     +
3717 :     structure BTrace -> structure TDPInstrument
3718 :     etc.
3719 :     +
3720 :     This is is preparation of using the original back-trace
3721 :     instrumentation for other purposes. "TDP" stands for
3722 :     Trace/Debug/Profile.
3723 :     +
3724 :     The control flag controlling whether instrumentation is on or off is now
3725 :     registered under a different name, so instead of running sml as
3726 :     +
3727 :     sml -Cinstrument.btrace-mode=true
3728 :     +

3736 :     [2004/10/11]::
3737 :     +
3738 :     Made some minor modifications to elabcore.sml to have source regions
3739 :     be propagated more tightly -- resulting in better (_i.e._, smaller)
3740 :     regions being reported in error- and debug messages.

3744 :     //--------------------------------------------------------------------
3745 :     [2004/10/08]::
3746 :     +
3747 :     Fixed handling of keywords in .cm files: After seeing "is" the lexer
3748 :     treats subsequent occurrences of "group", "library", "source", "is",
3749 :     "*", and "-" as ordinary identifiers rather than keywords.
3750 :     +
3751 :     Most seriously, this fixes a problem with CM's "shell" tool. The tool
3752 :     is supposed to accept a tool argument called "source", but this did
3753 :     not work because of the clash with the keyword.

3759 :     +
3760 :     Assorted cleanup work:
3761 :     +
3762 :     - got rid of intstrmap in favor of using the library's
3763 :     hash table implementation
3764 :     - threw out most of the pathnames stuff, as it was not used anyway
3765 :     - simplified tokentable implementation
3766 :     - fixed some minor spelling errors

3770 :     //--------------------------------------------------------------------
3771 :     [2004/10/06]::
3772 :     +
3773 :     Cleaned up the absyn to reflect the invariant that HANDLE always
3774 :     carries a FNexp as part of the type definition. This eliminates some
3775 :     superfluous sanity checks at runtime down the road.
3776 :     +
3777 :     Some minor cleanup of the btrace code.

3781 :     //--------------------------------------------------------------------
3782 :     [2004/10/01]::
3783 :     +
3784 :     Added hack to make slave mode work in the presence of the version
3785 :     tool. (Still, since the master does two passes over the code for
3786 :     CMB.make, the release number gets bumped twice when slaves are
3787 :     attached. I don't know if this is worth fixing...)

3791 :     //--------------------------------------------------------------------
3792 :     [2004/09/30]::
3793 :     +
3794 :     * Moved the "version" magic into its own little library under
3795 :     src/system/smlnj/internal. This avoids expensive reconstruction of
3796 :     a stable src/compiler/core.cm.
3797 :     +
3798 :     * At the same time, structure CompilerVersion is now known as
3799 :     structure SMLNJVersion.
3800 :     +
3801 :     * Arranged for the version tool to NOT kick in when rebuilding the system
3802 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.
3803 :     Also, loading the versiontool does not work when rebuilding the system
3804 :     because CM is not properly initialized at that time.

3808 :     //--------------------------------------------------------------------
3809 :     [2004/09/29]::
3810 :     +
3811 :     Implemented some CM magic to have
3812 :     file src/compiler/TopLevel/main/version.sml
3813 :     generated automagically.
3814 :     The version is taken from two files: config/version and config/release.
3815 :     The first is expected to contain a two-part version number such as 110.49.
3816 :     The second should contain a single number, but it may be missing.
3817 :     +
3818 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
3819 :     time the version tool is loaded (which is the first time you say CMB.make),
3820 :     then the tool will increment the value stored in config/release every
3821 :     time CMB.make is invoked.
3822 :     +
3823 :     The binfile format is now insensitive to anything beyond the first
3824 :     two components of a version number, so bumping the release does not render
3825 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
3826 :     during development without invalidating existing binfiles.
3827 :     +
3828 :     In any case, every CMB.make updates the date information in version.sml.

3858 : jhr 3995 stores the given value into the control in stage 2 (_i.e._, delayed)
3859 :     but does all error checking in stage 1.
3860 :     (This is for string controls that need to do parse their argument --
3861 :     something that might fail. In some cases, notably in CM, one
3862 :     already knows the intended argument but wants to delay the actual
