19    Description:
20    
21    Simpler and at the same time more general implementation of structure
22    Atom in CML.

28    Description:
29    
30    Created new "tools" directory under "src" and moved "TraceDebugProf"
31    there.

36    Tag: blume-20050210-longlong
37    Description:
38    
39    Implemented "long long" arguments and results for NLFFI.  (Only the
40    PPC/MacOS implementation is complete, the other backends still need to
41    be updated.)

46    Tag: blume-20050124-mlyacc
47    Description:
48    
49    Minor cleanup in ML-Yacc rule printing mechanism.  This should fix a
50    problem with certain "as" patterns which previously got rendered
51    using incorrect syntax.

57    Description:
58    
59    Made time profiling code (interrupt handler) in runtime system aware
60    of new array representation.

65    Tag: blume-20050114-heap2exec
66    Description:
67    
68    Implemented new (but still experimental) heap2exec facility.  This is
69    tested under Mac OS X and should work under Linux (will test shortly).
70    It will probably also work on the Sparc (will test some time later).
71    
72      - removed old "HACKED_STANDALONE" hack from runtime
73    
74    To be able to test this, uncomment the request for "heap2asm" in
75    config/targets prior to installation.  (Notice that this is different
76    from "heap2exec" mentioned below.  Not a typo.)
77    
78    To perform an actual test, run the command
79    
80       $ bin/heap2exec heapfile execfile
81    
82    (You can put heap2exec on your shell's path.)
83    
84    For example, run
85    
86      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
87    
88    This will create a standalone executable called "mly" which you can
89    then invoke directly as a command.

102    Tag: blume-20041223-santa
103    Description:
104    
105    Made ml-build script "smarter" (but only very little).
106    
107    ----------------------------------------------------------------------
108    Name: Matthias Blume (blume (at) tti - c (dot) org)
109    Date: 2004/12/21 15:05:00 CST
110    Tag: blume-20041221-longlong
111    Description:
112    
113    * Implemented access to signed and unsigned long long data in NLFFI.
114    (The parameter-passing part of the picture has not complete. But
115    data structure access seems to work.)
116    
117    * Fixed CM's incorrect assumption that the PPC is little-endian.
118      (On the Mac, it is big-endian.  And that's currently our only
119      PPC platform.)
120

124    Tag: blume-20041221-memory
125    Description:
126    
127    Some cleanup in the $c/memory.cm library: separated some concerns by
128    moving allocation code and memory access code each into their own
129    files.
130

134    Tag: leunga-20041217-cygwin-smlnj-home
135    Description:
136    
137        The Unix I/O library of SML/NJ on cygwin does not understand
138    Windows style pathname, so problems arise when SMLNJ_HOME is set
139    to a Windows style pathname.  _run-sml now converts SMLNJ_HOME
140    to a POSIX pathname on cygwin.

159    
160    - HashString.hashString' -> HashString.hashSubstring
161    - corresponding changes in atom.sml
162    - "de-compressed" (aka. un-obfuscated) code for UnivariateStats and
163      added some comments

183    Date: 2004/12/14 17:30:00 CST
184    Tag: blume-20041214-spaces
185    Description:
186    
187    Hacked some of the scripts (in particular: the installer) to cope with
188    spaces in filenames a bit better.  But beware: the current "solution"
189    is likely still full of bugs and inherently incomplete.  (We need to
190    do away with those shell scripts for a comprehensive solution.)

203    Tag: blume-20041209-statistics
204    Description:
205    
206    Added two simple but potentially useful statistics modules to SML/NJ Library.
207    (See CHANGES file there.)

213    Description:
214    
215    smlnj-lib:
216    
217      Added function HashString.hashString' for substrings.
218      Hand-inlined CharVector.foldl into HashString (for speed).
219      Modified implementation of structure Atom to avoid extracting
220      strings from substrings unless necessary.
221      (Also see CHANGES file for smlnj-lib.)

226    Tag: blume-20041124-cml
227    Description:
228    
229    Made sure CML compiles when Position = Int64.
230

232    Name: Matthias Blume (blume (at) tti - c (dot) org)
233    Date: 2004/11/24 14:30:00 CST
234    Tag: blume-20041124-position
235    Description:
236    
237    The compiler can now be compiled in a mode that makes structure Position
238    equal to Int64.  The default, however, is unchanged (Position = Int31)
239    for the time being.
240    
241    To enable 64-bit positions, use the following procedure:
242    
243    1. Start sml
244    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
245    3. Type
246          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
247    4. Run CMB.make() as usual.
248    
249    This is barely tested.  The only test so far was a little SML program
250    counting the number of characters in an 8-gigabyte file by
251    reading it character-by-character.  That test was successful.
252    
253    In support of 64-bit positions, a number of new functions have been
254    added to the runtime system.

259    Tag: blume-20041123-useFile
260    Description:
261    
262    Fixed a problem with unhelpful error messages related to problems with
263    .cm- or .sml files that appear as part of the sml command line.
264

285    Tag: leunga-20041117-mlrisc-live-kill
286    Description:
287    
288       Added support for MLTree constructs LIVE and KILL
289    to all the architectures.

294    Tag: blume-20041113-versiontool
295    Description:
296    
297    - Stripped down the versiontool: It now only handles the version number.
298      The date string is generated at bootstrap time (during makeml).
299    
300    - In a previous commit, fixed a minor issue with how polyequal is being
301      translated.  In particular, the code now "looks through" abstractions.
302      This results in slightly fewer polyEqual warnings and hopefully slightly
303      more efficient code.  Important examples for where this matters are
304      the new int64 and word64 types.
305

310    Description:
311    
312    Structure Int64 fully hooked in.  (The implementation is not very
313    efficient, though.)

318    Tag: blume-20041111-more64
319    Description:
320    
321    All the pieces of Word64 are now there, with the exception of the
322    conversions from and to LargeWord. (Eventually these need to be identities,
323    but for the time being they don't even make sense because LargeWord is
324    32-bit wide.)
325    
326    Also started to add similar support for Int64, but major pieces of that
327    are still missing.
328    
329    ----------------------------------------------------------------------
330    Name: Matthias Blume (blume (at) tti - c (dot) org)
331    Date: 2004/11/11 00:15:00 CST
332    Tag: blume-20041111-word64
333    Description:
334    
335    Structure Word64 is now (almost) complete, word literals and patterns
336    seem to work.  There are a few odd pieces missing.  In particular,
337    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
338    at the moment.
339    
340    Making Word64 official would mean that LargeWord becomes Word64.  But
341    this requires extreme care because most word-word conversions have to
342    go through LargeWord, so making a mistake means loss of efficiency or
343    worse.  Eventually there will be a solution similar to (but actually
344    simpler than) what I did with IntInf.

350    Description:
351    
352    More 64-bit hacking (but still not even half-way there yet).
353    Also, some assorted improvements to the handling of 8-bit words.

362    word-types.  (Still in its very early stages.)

370    New working version (110.50).  NEW BOOTFILES!
371    
372                 =====================
373    
374    Also:
375    
376      - Changend config/srcarchiveurl from a file just
377        containing the URL string into a file containing
378        shell script code.  The code has access to the $VERSION variable.
379      - Made corresponding changes to config/install.sh and config/unpack.
380      - Default contents of config/srcarchiveurl uses $VERSION and
381        normally does not have to be edited to reflect a version change.
382    
383      (As a result, a version change can be done by just editing
384       config/version, the rest is now automatic.)

400    
401    This is the HISTORY entry for two earlier commits, both concerning
402    the x86 c-calls code in MLRISC:
403    
404      - added a missing LOAD in the code that deals with struct arguments
405      - made sure the caller does not add the wrong number of bytes to the
406        stack pointer after a call of a function returning a struct
407        (the callee already pops the implicit argument which points to
408         the space reserved for the result)
