19    Description:
20    
21    Made time profiling code (interrupt handler) in runtime system aware
22    of new array representation.

27    Tag: blume-20050114-heap2exec
28    Description:
29    
30    Implemented new (but still experimental) heap2exec facility.  This is
31    tested under Mac OS X and should work under Linux (will test shortly).
32    It will probably also work on the Sparc (will test some time later).
33    
34      - removed old "HACKED_STANDALONE" hack from runtime
35    
36    To be able to test this, uncomment the request for "heap2asm" in
37    config/targets prior to installation.  (Notice that this is different
38    from "heap2exec" mentioned below.  Not a typo.)
39    
40    To perform an actual test, run the command
41    
42       $ bin/heap2exec heapfile execfile
43    
44    (You can put heap2exec on your shell's path.)
45    
46    For example, run
47    
48      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
49    
50    This will create a standalone executable called "mly" which you can
51    then invoke directly as a command.

56    Tag: blume-20050107-mlstring
57    Description:
58    
59    fixed off-by-one error in ML_STRING macro (globals.c)
60

64    Tag: blume-20041223-santa
65    Description:
66    
67    Made ml-build script "smarter" (but only very little).
68

72    Tag: blume-20041221-longlong
73    Description:
74    
75    * Implemented access to signed and unsigned long long data in NLFFI.
76    (The parameter-passing part of the picture has not complete. But
77    data structure access seems to work.)
78    
79    * Fixed CM's incorrect assumption that the PPC is little-endian.
80      (On the Mac, it is big-endian.  And that's currently our only
81      PPC platform.)

86    Tag: blume-20041221-memory
87    Description:
88    
89    Some cleanup in the $c/memory.cm library: separated some concerns by
90    moving allocation code and memory access code each into their own
91    files.

96    Tag: leunga-20041217-cygwin-smlnj-home
97    Description:
98    
99        The Unix I/O library of SML/NJ on cygwin does not understand
100    Windows style pathname, so problems arise when SMLNJ_HOME is set
101    to a Windows style pathname.  _run-sml now converts SMLNJ_HOME
102    to a POSIX pathname on cygwin.

119    Tag: blume-20041215-hashSubstring
120    Description:
121    
122    - HashString.hashString' -> HashString.hashSubstring
123    - corresponding changes in atom.sml
124    - "de-compressed" (aka. un-obfuscated) code for UnivariateStats and
125      added some comments
126

141    More on the space problem (this time for Win32).
142

145    Date: 2004/12/14 17:30:00 CST
146    Tag: blume-20041214-spaces
147    Description:
148    
149    Hacked some of the scripts (in particular: the installer) to cope with
150    spaces in filenames a bit better.  But beware: the current "solution"
151    is likely still full of bugs and inherently incomplete.  (We need to
152    do away with those shell scripts for a comprehensive solution.)

165    Tag: blume-20041209-statistics
166    Description:
167    
168    Added two simple but potentially useful statistics modules to SML/NJ Library.
169    (See CHANGES file there.)
170    
171    ----------------------------------------------------------------------
172    Name: Matthias Blume (blume (at) tti - c (dot) org)
173    Date: 2004/12/01 16:50:00 CST
174    Tag: blume-20041201-atom
175    Description:
176    
177    smlnj-lib:
178    
179      Added function HashString.hashString' for substrings.
180      Hand-inlined CharVector.foldl into HashString (for speed).
181      Modified implementation of structure Atom to avoid extracting
182      strings from substrings unless necessary.
183      (Also see CHANGES file for smlnj-lib.)

188    Tag: blume-20041124-cml
189    Description:
190    
191    Made sure CML compiles when Position = Int64.
192    
193    ----------------------------------------------------------------------
194    Name: Matthias Blume (blume (at) tti - c (dot) org)
195    Date: 2004/11/24 14:30:00 CST
196    Tag: blume-20041124-position
197    Description:
198    
199    The compiler can now be compiled in a mode that makes structure Position
200    equal to Int64.  The default, however, is unchanged (Position = Int31)
201    for the time being.
202    
203    To enable 64-bit positions, use the following procedure:
204    
205    1. Start sml
206    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
207    3. Type
208          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
209    4. Run CMB.make() as usual.
210    
211    This is barely tested.  The only test so far was a little SML program
212    counting the number of characters in an 8-gigabyte file by
213    reading it character-by-character.  That test was successful.
214    
215    In support of 64-bit positions, a number of new functions have been
216    added to the runtime system.

220    Date: 2004/11/23 14:45:00 CST
221    Tag: blume-20041123-useFile
222    Description:
223    
224    Fixed a problem with unhelpful error messages related to problems with
225    .cm- or .sml files that appear as part of the sml command line.
226

238    Tag: <none>
239    Description:
240    
241    Enabled dlopen and friends for FreeBSD (as recommended by Johannes 5
242    Joemann).

247    Tag: leunga-20041117-mlrisc-live-kill
248    Description:
249    
250       Added support for MLTree constructs LIVE and KILL
251    to all the architectures.

256    Tag: blume-20041113-versiontool
257    Description:
258    
259    - Stripped down the versiontool: It now only handles the version number.
260      The date string is generated at bootstrap time (during makeml).
261    
262    - In a previous commit, fixed a minor issue with how polyequal is being
263      translated.  In particular, the code now "looks through" abstractions.
264      This results in slightly fewer polyEqual warnings and hopefully slightly
265      more efficient code.  Important examples for where this matters are
266      the new int64 and word64 types.
267

271    Tag: blume-20041112-int64
272    Description:
273    
274    Structure Int64 fully hooked in.  (The implementation is not very
275    efficient, though.)
276

279    Date: 2004/11/11 17:30:00 CST
280    Tag: blume-20041111-more64
281    Description:
282    
283    All the pieces of Word64 are now there, with the exception of the
284    conversions from and to LargeWord. (Eventually these need to be identities,
285    but for the time being they don't even make sense because LargeWord is
286    32-bit wide.)
287    
288    Also started to add similar support for Int64, but major pieces of that
289    are still missing.
290    
291    ----------------------------------------------------------------------
292    Name: Matthias Blume (blume (at) tti - c (dot) org)
293    Date: 2004/11/11 00:15:00 CST
294    Tag: blume-20041111-word64
295    Description:
296    
297    Structure Word64 is now (almost) complete, word literals and patterns
298    seem to work.  There are a few odd pieces missing.  In particular,
299    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
300    at the moment.
301    
302    Making Word64 official would mean that LargeWord becomes Word64.  But
303    this requires extreme care because most word-word conversions have to
304    go through LargeWord, so making a mistake means loss of efficiency or
305    worse.  Eventually there will be a solution similar to (but actually
306    simpler than) what I did with IntInf.
307

311    Tag: blume-20041110-64bit
312    Description:
313    
314    More 64-bit hacking (but still not even half-way there yet).
315    Also, some assorted improvements to the handling of 8-bit words.
316

319    Date: 2004/11/09 17:50:00 CST
320    Tag: <none>
321    Description:
322    
323    Started adding some infrastructure for supporting 64-bit int- and
324    word-types.  (Still in its very early stages.)
325

329    Tag: Release_110_50
330    Description:
331    
332    New working version (110.50).  NEW BOOTFILES!
333    
334                 =====================
335    
336    Also:
337    
338      - Changend config/srcarchiveurl from a file just
339        containing the URL string into a file containing
340        shell script code.  The code has access to the $VERSION variable.
341      - Made corresponding changes to config/install.sh and config/unpack.
342      - Default contents of config/srcarchiveurl uses $VERSION and
343        normally does not have to be edited to reflect a version change.
344    
345      (As a result, a version change can be done by just editing
346       config/version, the rest is now automatic.)
