18    Tag: blume-20050210-longlong
19    Description:
20    
21    Implemented "long long" arguments and results for NLFFI.  (Only the
22    PPC/MacOS implementation is complete, the other backends still need to
23    be updated.)

28    Tag: blume-20050124-mlyacc
29    Description:
30    
31    Minor cleanup in ML-Yacc rule printing mechanism.  This should fix a
32    problem with certain "as" patterns which previously got rendered
33    using incorrect syntax.

39    Description:
40    
41    Made time profiling code (interrupt handler) in runtime system aware
42    of new array representation.

47    Tag: blume-20050114-heap2exec
48    Description:
49    
50    Implemented new (but still experimental) heap2exec facility.  This is
51    tested under Mac OS X and should work under Linux (will test shortly).
52    It will probably also work on the Sparc (will test some time later).
53    
54      - removed old "HACKED_STANDALONE" hack from runtime
55    
56    To be able to test this, uncomment the request for "heap2asm" in
57    config/targets prior to installation.  (Notice that this is different
58    from "heap2exec" mentioned below.  Not a typo.)
59    
60    To perform an actual test, run the command
61    
62       $ bin/heap2exec heapfile execfile
63    
64    (You can put heap2exec on your shell's path.)
65    
66    For example, run
67    
68      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
69    
70    This will create a standalone executable called "mly" which you can
71    then invoke directly as a command.

83    Date: 2004/12/23 18:00:00 CST
84    Tag: blume-20041223-santa
85    Description:
86    
87    Made ml-build script "smarter" (but only very little).
88

90    Name: Matthias Blume (blume (at) tti - c (dot) org)
91    Date: 2004/12/21 15:05:00 CST
92    Tag: blume-20041221-longlong
93    Description:
94    
95    * Implemented access to signed and unsigned long long data in NLFFI.
96    (The parameter-passing part of the picture has not complete. But
97    data structure access seems to work.)
98    
99    * Fixed CM's incorrect assumption that the PPC is little-endian.
100      (On the Mac, it is big-endian.  And that's currently our only
101      PPC platform.)
102

106    Tag: blume-20041221-memory
107    Description:
108    
109    Some cleanup in the $c/memory.cm library: separated some concerns by
110    moving allocation code and memory access code each into their own
111    files.

116    Tag: leunga-20041217-cygwin-smlnj-home
117    Description:
118    
119        The Unix I/O library of SML/NJ on cygwin does not understand
120    Windows style pathname, so problems arise when SMLNJ_HOME is set
121    to a Windows style pathname.  _run-sml now converts SMLNJ_HOME
122    to a POSIX pathname on cygwin.

129    
130    Last-minute changes incorporated into 110.52.  Release tag moved.
131    
132    The changes:
133       - HashString.hashString' -> HashString.hashSubstring

140    Description:
141    
142    - HashString.hashString' -> HashString.hashSubstring
143    - corresponding changes in atom.sml
144    - "de-compressed" (aka. un-obfuscated) code for UnivariateStats and
145      added some comments

164    Name: Matthias Blume (blume (at) tti - c (dot) org)
165    Date: 2004/12/14 17:30:00 CST
166    Tag: blume-20041214-spaces
167    Description:
168    
169    Hacked some of the scripts (in particular: the installer) to cope with
170    spaces in filenames a bit better.  But beware: the current "solution"
171    is likely still full of bugs and inherently incomplete.  (We need to
172    do away with those shell scripts for a comprehensive solution.)
173

185    Tag: blume-20041209-statistics
186    Description:
187    
188    Added two simple but potentially useful statistics modules to SML/NJ Library.
189    (See CHANGES file there.)

194    Tag: blume-20041201-atom
195    Description:
196    
197    smlnj-lib:
198    
199      Added function HashString.hashString' for substrings.
200      Hand-inlined CharVector.foldl into HashString (for speed).
201      Modified implementation of structure Atom to avoid extracting
202      strings from substrings unless necessary.
203      (Also see CHANGES file for smlnj-lib.)

208    Tag: blume-20041124-cml
209    Description:
210    
211    Made sure CML compiles when Position = Int64.
212    
213    ----------------------------------------------------------------------
214    Name: Matthias Blume (blume (at) tti - c (dot) org)
215    Date: 2004/11/24 14:30:00 CST
216    Tag: blume-20041124-position
217    Description:
218    
219    The compiler can now be compiled in a mode that makes structure Position
220    equal to Int64.  The default, however, is unchanged (Position = Int31)
221    for the time being.
222    
223    To enable 64-bit positions, use the following procedure:
224    
225    1. Start sml
226    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
227    3. Type
228          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
229    4. Run CMB.make() as usual.
230    
231    This is barely tested.  The only test so far was a little SML program
232    counting the number of characters in an 8-gigabyte file by
233    reading it character-by-character.  That test was successful.
234    
235    In support of 64-bit positions, a number of new functions have been
236    added to the runtime system.

241    Tag: blume-20041123-useFile
242    Description:
243    
244    Fixed a problem with unhelpful error messages related to problems with
245    .cm- or .sml files that appear as part of the sml command line.
246

259    Description:
260

262    Joemann).

267    Tag: leunga-20041117-mlrisc-live-kill
268    Description:
269    
270       Added support for MLTree constructs LIVE and KILL
271    to all the architectures.

276    Tag: blume-20041113-versiontool
277    Description:
278    
279    - Stripped down the versiontool: It now only handles the version number.
280      The date string is generated at bootstrap time (during makeml).
281    
282    - In a previous commit, fixed a minor issue with how polyequal is being
283      translated.  In particular, the code now "looks through" abstractions.
284      This results in slightly fewer polyEqual warnings and hopefully slightly
285      more efficient code.  Important examples for where this matters are
286      the new int64 and word64 types.
287

291    Tag: blume-20041112-int64
292    Description:
293    
294    Structure Int64 fully hooked in.  (The implementation is not very
295    efficient, though.)

300    Tag: blume-20041111-more64
301    Description:
302    
303    All the pieces of Word64 are now there, with the exception of the
304    conversions from and to LargeWord. (Eventually these need to be identities,
305    but for the time being they don't even make sense because LargeWord is
306    32-bit wide.)
307    
308    Also started to add similar support for Int64, but major pieces of that
309    are still missing.
310    
311    ----------------------------------------------------------------------
312    Name: Matthias Blume (blume (at) tti - c (dot) org)
313    Date: 2004/11/11 00:15:00 CST
314    Tag: blume-20041111-word64
315    Description:
316    
317    Structure Word64 is now (almost) complete, word literals and patterns
318    seem to work.  There are a few odd pieces missing.  In particular,
319    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
320    at the moment.
321    
322    Making Word64 official would mean that LargeWord becomes Word64.  But
323    this requires extreme care because most word-word conversions have to
324    go through LargeWord, so making a mistake means loss of efficiency or
325    worse.  Eventually there will be a solution similar to (but actually
326    simpler than) what I did with IntInf.
327

331    Tag: blume-20041110-64bit
332    Description:
333    
334    More 64-bit hacking (but still not even half-way there yet).
335    Also, some assorted improvements to the handling of 8-bit words.

341    Description:
342    
343    Started adding some infrastructure for supporting 64-bit int- and
344    word-types.  (Still in its very early stages.)

350    Description:
351    
352    New working version (110.50).  NEW BOOTFILES!
353    
354                 =====================
355    
356    Also:
357    
358      - Changend config/srcarchiveurl from a file just
359        containing the URL string into a file containing
360        shell script code.  The code has access to the $VERSION variable.
361      - Made corresponding changes to config/install.sh and config/unpack.
362      - Default contents of config/srcarchiveurl uses $VERSION and
363        normally does not have to be edited to reflect a version change.
364    
365      (As a result, a version change can be done by just editing
366       config/version, the rest is now automatic.)

381    Description:
382    
383    This is the HISTORY entry for two earlier commits, both concerning
384    the x86 c-calls code in MLRISC:
385    
386      - added a missing LOAD in the code that deals with struct arguments
387      - made sure the caller does not add the wrong number of bytes to the
388        stack pointer after a call of a function returning a struct
389        (the callee already pops the implicit argument which points to
390         the space reserved for the result)
