19    Description:
20    
21    - HashString.hashString' -> HashString.hashSubstring
22    - corresponding changes in atom.sml
23    - "de-compressed" (aka. un-obfuscated) code for UnivariateStats and
24      added some comments

38    Description:

45    Tag: blume-20041214-spaces
46    Description:
47    
48    Hacked some of the scripts (in particular: the installer) to cope with
49    spaces in filenames a bit better.  But beware: the current "solution"
50    is likely still full of bugs and inherently incomplete.  (We need to
51    do away with those shell scripts for a comprehensive solution.)

64    Tag: blume-20041209-statistics
65    Description:
66    
67    Added two simple but potentially useful statistics modules to SML/NJ Library.
68    (See CHANGES file there.)

73    Tag: blume-20041201-atom
74    Description:
75    
76    smlnj-lib:
77    
78      Added function HashString.hashString' for substrings.
79      Hand-inlined CharVector.foldl into HashString (for speed).
80      Modified implementation of structure Atom to avoid extracting
81      strings from substrings unless necessary.
82      (Also see CHANGES file for smlnj-lib.)

87    Tag: blume-20041124-cml
88    Description:
89    
90    Made sure CML compiles when Position = Int64.
91    
92    ----------------------------------------------------------------------
93    Name: Matthias Blume (blume (at) tti - c (dot) org)
94    Date: 2004/11/24 14:30:00 CST
95    Tag: blume-20041124-position
96    Description:
97    
98    The compiler can now be compiled in a mode that makes structure Position
99    equal to Int64.  The default, however, is unchanged (Position = Int31)
100    for the time being.
101    
102    To enable 64-bit positions, use the following procedure:
103    
104    1. Start sml
105    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
106    3. Type
107          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
108    4. Run CMB.make() as usual.
109    
110    This is barely tested.  The only test so far was a little SML program
111    counting the number of characters in an 8-gigabyte file by
112    reading it character-by-character.  That test was successful.
113    
114    In support of 64-bit positions, a number of new functions have been
115    added to the runtime system.

120    Tag: blume-20041123-useFile
121    Description:
122    
123    Fixed a problem with unhelpful error messages related to problems with
124    .cm- or .sml files that appear as part of the sml command line.
125    
126    ----------------------------------------------------------------------

132    New working version (110.51).  NEW BOOTFILES!

136    Date: 2004/11/18 15:35:00 CST
137    Tag: <none>
138    Description:
139    
140    Enabled dlopen and friends for FreeBSD (as recommended by Johannes 5
141    Joemann).

146    Tag: leunga-20041117-mlrisc-live-kill
147    Description:
148    
149       Added support for MLTree constructs LIVE and KILL
150    to all the architectures.
151

155    Tag: blume-20041113-versiontool
156    Description:
157    
158    - Stripped down the versiontool: It now only handles the version number.
159      The date string is generated at bootstrap time (during makeml).
160    
161    - In a previous commit, fixed a minor issue with how polyequal is being
162      translated.  In particular, the code now "looks through" abstractions.
163      This results in slightly fewer polyEqual warnings and hopefully slightly
164      more efficient code.  Important examples for where this matters are
165      the new int64 and word64 types.
166

169    Date: 2004/11/12 00:30:00 CST
170    Tag: blume-20041112-int64
171    Description:
172    
173    Structure Int64 fully hooked in.  (The implementation is not very
174    efficient, though.)
175

178    Date: 2004/11/11 17:30:00 CST
179    Tag: blume-20041111-more64
180    Description:
181    
182    All the pieces of Word64 are now there, with the exception of the
183    conversions from and to LargeWord. (Eventually these need to be identities,
184    but for the time being they don't even make sense because LargeWord is
185    32-bit wide.)
186    
187    Also started to add similar support for Int64, but major pieces of that
188    are still missing.
189    
190    ----------------------------------------------------------------------
191    Name: Matthias Blume (blume (at) tti - c (dot) org)
192    Date: 2004/11/11 00:15:00 CST
193    Tag: blume-20041111-word64
194    Description:
195    
196    Structure Word64 is now (almost) complete, word literals and patterns
197    seem to work.  There are a few odd pieces missing.  In particular,
198    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
199    at the moment.
200    
201    Making Word64 official would mean that LargeWord becomes Word64.  But
202    this requires extreme care because most word-word conversions have to
203    go through LargeWord, so making a mistake means loss of efficiency or
204    worse.  Eventually there will be a solution similar to (but actually
205    simpler than) what I did with IntInf.
206

210    Tag: blume-20041110-64bit
211    Description:
212    
213    More 64-bit hacking (but still not even half-way there yet).
214    Also, some assorted improvements to the handling of 8-bit words.
215

218    Date: 2004/11/09 17:50:00 CST
219    Tag: <none>
220    Description:
221    
222    Started adding some infrastructure for supporting 64-bit int- and
223    word-types.  (Still in its very early stages.)
224

227    Date: 2004/10/28 10:45:00 CDT
228    Tag: Release_110_50
229    Description:
230    
231    New working version (110.50).  NEW BOOTFILES!
232    
233                 =====================
234    
235    Also:
236    
237      - Changend config/srcarchiveurl from a file just
238        containing the URL string into a file containing
239        shell script code.  The code has access to the $VERSION variable.
240      - Made corresponding changes to config/install.sh and config/unpack.
241      - Default contents of config/srcarchiveurl uses $VERSION and
242        normally does not have to be edited to reflect a version change.
243    
244      (As a result, a version change can be done by just editing
245       config/version, the rest is now automatic.)

251    Description:
252    
253    BackTrace.monitor now also reports the source of the exception that
254    triggered the trace.

259    Tag: blume-20041027-x86-c-calls
260    Description:
261    
262    This is the HISTORY entry for two earlier commits, both concerning
263    the x86 c-calls code in MLRISC:
264    
265      - added a missing LOAD in the code that deals with struct arguments
266      - made sure the caller does not add the wrong number of bytes to the
267        stack pointer after a call of a function returning a struct
268        (the callee already pops the implicit argument which points to
269         the space reserved for the result)
