18    Tag: blume-20050114-heap2exec
19    Description:
20    
21    Implemented new (but still experimental) heap2exec facility.  This is
22    tested under Mac OS X and should work under Linux (will test shortly).
23    It will probably also work on the Sparc (will test some time later).
24    
25      - removed old "HACKED_STANDALONE" hack from runtime
26    
27    To be able to test this, uncomment the request for "heap2asm" in
28    config/targets prior to installation.  (Notice that this is different
29    from "heap2exec" mentioned below.  Not a typo.)
30    
31    To perform an actual test, run the command
32    
33       $ bin/heap2exec heapfile execfile
34    
35    (You can put heap2exec on your shell's path.)
36    
37    For example, run
38    
39      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
40    
41    This will create a standalone executable called "mly" which you can
42    then invoke directly as a command.

48    Description:

50    fixed off-by-one error in ML_STRING macro (globals.c)

56    Description:
57    
58    Made ml-build script "smarter" (but only very little).

63    Tag: blume-20041221-longlong
64    Description:
65    
66    * Implemented access to signed and unsigned long long data in NLFFI.
67    (The parameter-passing part of the picture has not complete. But
68    data structure access seems to work.)
69    
70    * Fixed CM's incorrect assumption that the PPC is little-endian.
71      (On the Mac, it is big-endian.  And that's currently our only
72      PPC platform.)

78    Description:
79    
80    Some cleanup in the $c/memory.cm library: separated some concerns by
81    moving allocation code and memory access code each into their own
82    files.

87    Tag: leunga-20041217-cygwin-smlnj-home
88    Description:
89    
90        The Unix I/O library of SML/NJ on cygwin does not understand
91    Windows style pathname, so problems arise when SMLNJ_HOME is set
92    to a Windows style pathname.  _run-sml now converts SMLNJ_HOME
93    to a POSIX pathname on cygwin.

113    - HashString.hashString' -> HashString.hashSubstring
114    - corresponding changes in atom.sml
115    - "de-compressed" (aka. un-obfuscated) code for UnivariateStats and
116      added some comments

137    Tag: blume-20041214-spaces
138    Description:
139    
140    Hacked some of the scripts (in particular: the installer) to cope with
141    spaces in filenames a bit better.  But beware: the current "solution"
142    is likely still full of bugs and inherently incomplete.  (We need to
143    do away with those shell scripts for a comprehensive solution.)

156    Tag: blume-20041209-statistics
157    Description:
158    
159    Added two simple but potentially useful statistics modules to SML/NJ Library.
160    (See CHANGES file there.)

165    Tag: blume-20041201-atom
166    Description:
167    
168    smlnj-lib:
169    
170      Added function HashString.hashString' for substrings.
171      Hand-inlined CharVector.foldl into HashString (for speed).
172      Modified implementation of structure Atom to avoid extracting
173      strings from substrings unless necessary.
174      (Also see CHANGES file for smlnj-lib.)

179    Tag: blume-20041124-cml
180    Description:
181    
182    Made sure CML compiles when Position = Int64.
183

187    Tag: blume-20041124-position
188    Description:
189    
190    The compiler can now be compiled in a mode that makes structure Position
191    equal to Int64.  The default, however, is unchanged (Position = Int31)
192    for the time being.
193    
194    To enable 64-bit positions, use the following procedure:
195    
196    1. Start sml
197    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
198    3. Type
199          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
200    4. Run CMB.make() as usual.
201    
202    This is barely tested.  The only test so far was a little SML program
203    counting the number of characters in an 8-gigabyte file by
204    reading it character-by-character.  That test was successful.
205    
206    In support of 64-bit positions, a number of new functions have been
207    added to the runtime system.

212    Tag: blume-20041123-useFile
213    Description:
214    
215    Fixed a problem with unhelpful error messages related to problems with
216    .cm- or .sml files that appear as part of the sml command line.

233    Joemann).

239    Description:
240    
241       Added support for MLTree constructs LIVE and KILL
242    to all the architectures.

247    Tag: blume-20041113-versiontool
248    Description:
249    
250    - Stripped down the versiontool: It now only handles the version number.
251      The date string is generated at bootstrap time (during makeml).
252    
253    - In a previous commit, fixed a minor issue with how polyequal is being
254      translated.  In particular, the code now "looks through" abstractions.
255      This results in slightly fewer polyEqual warnings and hopefully slightly
256      more efficient code.  Important examples for where this matters are
257      the new int64 and word64 types.

263    Description:
264    
265    Structure Int64 fully hooked in.  (The implementation is not very
266    efficient, though.)

271    Tag: blume-20041111-more64
272    Description:
273    
274    All the pieces of Word64 are now there, with the exception of the
275    conversions from and to LargeWord. (Eventually these need to be identities,
276    but for the time being they don't even make sense because LargeWord is
277    32-bit wide.)
278    
279    Also started to add similar support for Int64, but major pieces of that
280    are still missing.
281

284    Date: 2004/11/11 00:15:00 CST
285    Tag: blume-20041111-word64
286    Description:
287    
288    Structure Word64 is now (almost) complete, word literals and patterns
289    seem to work.  There are a few odd pieces missing.  In particular,
290    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
291    at the moment.
292    
293    Making Word64 official would mean that LargeWord becomes Word64.  But
294    this requires extreme care because most word-word conversions have to
295    go through LargeWord, so making a mistake means loss of efficiency or
296    worse.  Eventually there will be a solution similar to (but actually
297    simpler than) what I did with IntInf.
298
