19    Description:
20    
21    Minor cleanup in ML-Yacc rule printing mechanism.  This should fix a
22    problem with certain "as" patterns which previously got rendered
23    using incorrect syntax.

37    Tag: blume-20050114-heap2exec
38    Description:
39    
40    Implemented new (but still experimental) heap2exec facility.  This is
41    tested under Mac OS X and should work under Linux (will test shortly).
42    It will probably also work on the Sparc (will test some time later).
43    
44      - removed old "HACKED_STANDALONE" hack from runtime
45    
46    To be able to test this, uncomment the request for "heap2asm" in
47    config/targets prior to installation.  (Notice that this is different
48    from "heap2exec" mentioned below.  Not a typo.)
49    
50    To perform an actual test, run the command
51    
52       $ bin/heap2exec heapfile execfile
53    
54    (You can put heap2exec on your shell's path.)
55    
56    For example, run
57    
58      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
59    
60    This will create a standalone executable called "mly" which you can
61    then invoke directly as a command.

82    Tag: blume-20041221-longlong
83    Description:
84    
85    * Implemented access to signed and unsigned long long data in NLFFI.
86    (The parameter-passing part of the picture has not complete. But
87    data structure access seems to work.)
88    
89    * Fixed CM's incorrect assumption that the PPC is little-endian.
90      (On the Mac, it is big-endian.  And that's currently our only
91      PPC platform.)

97    Description:
98    
99    Some cleanup in the $c/memory.cm library: separated some concerns by
100    moving allocation code and memory access code each into their own
101    files.

107    Description:
108    
109        The Unix I/O library of SML/NJ on cygwin does not understand
110    Windows style pathname, so problems arise when SMLNJ_HOME is set
111    to a Windows style pathname.  _run-sml now converts SMLNJ_HOME
112    to a POSIX pathname on cygwin.

132    - HashString.hashString' -> HashString.hashSubstring
133    - corresponding changes in atom.sml
134    - "de-compressed" (aka. un-obfuscated) code for UnivariateStats and
135      added some comments

155    Date: 2004/12/14 17:30:00 CST
156    Tag: blume-20041214-spaces
157    Description:
158    
159    Hacked some of the scripts (in particular: the installer) to cope with
160    spaces in filenames a bit better.  But beware: the current "solution"
161    is likely still full of bugs and inherently incomplete.  (We need to
162    do away with those shell scripts for a comprehensive solution.)

174    Date: 2004/12/09 16:30:00 CST
175    Tag: blume-20041209-statistics
176    Description:
177    
178    Added two simple but potentially useful statistics modules to SML/NJ Library.
179    (See CHANGES file there.)

184    Tag: blume-20041201-atom
185    Description:
186    
187    smlnj-lib:
188    
189      Added function HashString.hashString' for substrings.
190      Hand-inlined CharVector.foldl into HashString (for speed).
191      Modified implementation of structure Atom to avoid extracting
192      strings from substrings unless necessary.
193      (Also see CHANGES file for smlnj-lib.)

198    Tag: blume-20041124-cml
199    Description:
200    
201    Made sure CML compiles when Position = Int64.
202

205    Date: 2004/11/24 14:30:00 CST
206    Tag: blume-20041124-position
207    Description:
208    
209    The compiler can now be compiled in a mode that makes structure Position
210    equal to Int64.  The default, however, is unchanged (Position = Int31)
211    for the time being.
212    
213    To enable 64-bit positions, use the following procedure:
214    
215    1. Start sml
216    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
217    3. Type
218          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
219    4. Run CMB.make() as usual.
220    
221    This is barely tested.  The only test so far was a little SML program
222    counting the number of characters in an 8-gigabyte file by
223    reading it character-by-character.  That test was successful.
224    
225    In support of 64-bit positions, a number of new functions have been
226    added to the runtime system.

232    Description:
233    
234    Fixed a problem with unhelpful error messages related to problems with
235    .cm- or .sml files that appear as part of the sml command line.

266    Tag: blume-20041113-versiontool
267    Description:
268    
269    - Stripped down the versiontool: It now only handles the version number.
270      The date string is generated at bootstrap time (during makeml).
271    
272    - In a previous commit, fixed a minor issue with how polyequal is being
273      translated.  In particular, the code now "looks through" abstractions.
274      This results in slightly fewer polyEqual warnings and hopefully slightly
275      more efficient code.  Important examples for where this matters are
276      the new int64 and word64 types.

290    Tag: blume-20041111-more64
291    Description:
292    
293    All the pieces of Word64 are now there, with the exception of the
294    conversions from and to LargeWord. (Eventually these need to be identities,
295    but for the time being they don't even make sense because LargeWord is
296    32-bit wide.)
297    
298    Also started to add similar support for Int64, but major pieces of that
299    are still missing.
300

304    Tag: blume-20041111-word64
305    Description:
306    
307    Structure Word64 is now (almost) complete, word literals and patterns
308    seem to work.  There are a few odd pieces missing.  In particular,
309    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
310    at the moment.
311    
312    Making Word64 official would mean that LargeWord becomes Word64.  But
313    this requires extreme care because most word-word conversions have to
314    go through LargeWord, so making a mistake means loss of efficiency or
315    worse.  Eventually there will be a solution similar to (but actually
316    simpler than) what I did with IntInf.

325    Also, some assorted improvements to the handling of 8-bit words.

343    
344                 =====================
345    
346    Also:
347    
348      - Changend config/srcarchiveurl from a file just
349        containing the URL string into a file containing
350        shell script code.  The code has access to the $VERSION variable.
351      - Made corresponding changes to config/install.sh and config/unpack.
352      - Default contents of config/srcarchiveurl uses $VERSION and
353        normally does not have to be edited to reflect a version change.
354    
355      (As a result, a version change can be done by just editing
356       config/version, the rest is now automatic.)

372    
373    This is the HISTORY entry for two earlier commits, both concerning
374    the x86 c-calls code in MLRISC:
375    
376      - added a missing LOAD in the code that deals with struct arguments
377      - made sure the caller does not add the wrong number of bytes to the
378        stack pointer after a call of a function returning a struct
379        (the callee already pops the implicit argument which points to
380         the space reserved for the result)

396    Tag: blume-20041020-standalone-backtrace
397    Description:
398    
399    Added a mechanism for getting back-trace information from standalone
400    programs.  Here is how it works:
401    
402       1. The part of the program from which you want to get backtrace
403          information (usually the whole program) should be wrapped with
404          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
405          main program could be modified from something like
406    
407             fun main (pgm, args) = ...
408    
409         to
410    
411            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
412    
413       2. To be able to access BackTrace.monitor, you have to add
414          library $smlnj-tdp/plugins.cm to the .cm file that contains your
415          main function.
416    
417       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
418          CM might have created in the past for your project).
419    
420       4. Build the system using this command line:
421    
422             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
423                      myprog.cm MyProg.main myprog
424    
425          instead of the usual
426    
427             ml-build myprog.cm MyProg.main myprog
428    
429    I changed a library name:
430    
431       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
432    
433    New libraries:
434    
435       $smlnj-tdp/back-trace.cm
436          -- when loaded causes the back-trace plugin to be installed
437       $smlnj-tdp/coverage.cm
438          -- when loaded causes the coverage plugin to be installed

453    Tag: blume-20041015-coverage
454    Description:
455    
456    * Test coverage tool added!
457    * Further reorganization of tracing-, debugging-, and profiling support:
458    
459        - moved original BTImp -- now called BackTrace -- into a separate
460          library called $/trace-debug-profile.cm
461        - eliminated all mentions of BTrace from SMLofNJ.Internals
462        - only the instrumentation mechanism is now left in the compiler proper
463        - BackTrace module is a plugin which is NOT plugged in by default
464        - Coverage module is another such plugin
465    
466    To get the benefits of any of these plugin modules, the code in
467    question must be compiled with tdp instrumentation turned on.  This
468    can be done by setting SMLofNJ.Internals.TDP.mode to true.
469    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
470    
471    Plugins are selected at link time.  (Pre-compiled instrumented code
472    can be re-loaded with different plugins in effect.)  When an
473    instrumented module is linked, whatever plugins are at that time
474    enabled will come into effect for that module.
475    
476    To enable the back-trace plugin, load library $/trace-debug-profile.cm
477    and invoke BackTrace.install() (e.g., from the interactive prompt).
478    To enable the coverage plugin, load the same library and invoke
479    Coverage.install().
480    
481    Back-traces are generated automatically on uncaught exceptions and
482    when the code in question explicitly invokes BackTrace.trigger().
483    
484    Coverage (and execution frequency-) information must be queried
485    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

501    
502    Some rationalization of names:
503    
504       structure BTrace -> structure TDPInstrument
505       etc.
506    
507    This is is preparation of using the original back-trace
508    instrumentation for other purposes.  "TDP" stands for
509    Trace/Debug/Profile.
510    
511    The control flag controlling whether instrumentation is on or off is now
512    registered under a different name, so instead of running sml as
513    
514     sml -Cinstrument.btrace-mode=true
515    
516    one has to say
517    
518     sml -Ctdp.instrument=true

534    Description:
535    
536    Fixed handling of keywords in .cm files: After seeing "is" the lexer
537    treats subsequent occurrences of "group", "library", "source", "is",
538    "*", and "-" as ordinary identifiers rather than keywords.
539    
540    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
541    is supposed to accept a tool argument called "source", but this did
542    not work because of the clash with the keyword.

585    Description:
586    
587    * Moved the "version" magic into its own little library under
588      src/system/smlnj/internal.  This avoids expensive reconstruction of
589      a stable src/compiler/core.cm.
590    
591    * At the same time, structure CompilerVersion is now known as
592      structure SMLNJVersion.
593    
594    * Arranged for the version tool to NOT kick in when rebuilding the system
595      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
596      Also, loading the versiontool does not work when rebuilding the system
597      because CM is not properly initialized at that time.

602    Tag: blume-20040929-autoversion
603    Description:
604    
605    Implemented some CM magic to have
606        file src/compiler/TopLevel/main/version.sml
607    generated automagically.
608    The version is taken from two files: config/version and config/release.
609    The first is expected to contain a two-part version number such as 110.49.
610    The second should contain a single number, but it may be missing.
611    
612    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
613    time the version tool is loaded (which is the first time you say CMB.make),
614    then the tool will increment the value stored in config/release every
615    time CMB.make is invoked.
616    
617    The binfile format is now insensitive to anything beyond the first
618    two components of a version number, so bumping the release does not render
619    binfiles incompatible.  Auto-bumping can be used to keep track of versions
620    during development without invalidating existing binfiles.
621    
622    In any case, every CMB.make updates the date information in version.sml.
623    (This is the date that is printed in the banner.)

636    Tag: blume-20040927-controls
637    Description:
638    
639    Added two pieces of functionality to the Controls interface:
640    
641    1.   val save'restore: 'a control -> unit -> unit
642    
643       grabs the current value of the control in stage 1 and restores it
644       in stage 2.
645    
646    2.   val set' : 'a control * 'a -> unit -> unit
647    
648       stores the given value into the control in stage 2 (i.e., delayed)
649       but does all error checking in stage 1.
650       (This is for string controls that need to do parse their argument --
651        something that might fail.  In some cases, notably in CM, one
652        already knows the intended argument but wants to delay the actual
653        assignment until a time when error recovery would be more difficult.)
654    
655    Changed the handling of controls in tool arguments to classes "sml" and
656    "lazysml":
657       - use Controls.save'restore as a more robust way of restoring the
658         old value (in particular: without having to re-parse the string)
659       - use controls to handle the "overload" keyword in the init group
660         (I believe this change actually fixes a long-standing obscure bug.)

665    Tag: blume-20040927-lazysml
666    Description:
667    
668    Added a new tool class called "lazysml" to CM's tool chest.  The only
669    difference to "sml" is that compilation is done with Control.lazysml
670    set to true.  A source of class "lazysml" is automatically recognized
671    by a file name suffix of ".lml".
672    
673    In addition to the above feature, the original class "sml" now also
674    supports a tool argument "lazy" which has the same effect.  As a
675    result, the following three lines are equivalent:
676    
677        foo.sml : lazysml
678        foo.sml : sml (lazy)
679        foo.sml (lazy)
680    
681    The setting goes into effect both during parsing and during
682    compilation.  The original setting is restored right after parsing and
683    after compilation, respectively.
684    
685    In addition to all the above, there is also a general mechanism to set
686    ANY of the "controls" that are available at the command line via
687    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
688    apply as well. (In fact, "lazy" is implemented as a special case of
689    the general mechanism.)
690    
691    The .cm file syntax uses a new keyword tool argument called "with".
692    There are several ways of indicating the desired settings:
693    
694        foo.sml (with:parser.quotations=true)
695        foo.sml (with:(name:parser.quotations value:true))
696        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
697        foo.sml (with:(name1=value1 name2=value2 ...))
698        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
699    
700        etc.
701    
702    Another possible abbreviation is to leave out the =v or value:v part
703    if the name refers to a boolean control (in which case the value is
704    taken to be true).  Thus, one could get lazy sml also by saying:
705    
706        foo.sml (with:parser.lazy-keyword=true)
707        foo.sml (with:parser.lazy-keyword)
708        foo.sml (with:(name:parser.lazy-keyword value:true))
709        foo.sml (with:(name:parser.lazy-keyword))
