18    Description:
19    
20    The main change is that I added function CM.sources as a generalized
21    version of the earlier CM.makedepend.  This entails the following
22    additional changes:
23    
24      - CM.makedepend has been dropped.
25    
26      - CM manual has been updated.
27    
28      - TOOLS signature and API have been changed.

34    Description:
35    
36      Various bug fixes and new features for C--, Moby and MLRISC optimizations.
37    None of these affect SML/NJ.
38    
39    1. Register Allocation
40    
41        a. A new ra spilling module (ra/ra-spill-with-renaming) is implemented.
42           This module tries to remove local (i.e. basic block level) redundancies
43           during spilling.
44    
45        b. A new framework for performing region based register allocation.
46           Not yet entirely functional.
47    
48    2. X86
49    
50       a. DefUse for POP was missing the stack pointer [found by Lal]
51       b. Reload for CALL was incorrect in X86Spill [found by John]
52       c. Various fixes in X86Spill so that it can be used correctly for
53          the new spilling module.
54    
55    3. SSA/IR
56    
57       a. New module ir/dj-dataflow.sml implements elimination based
58          data flow analysis.
59    
60    4. MLRiscGen
61    
62       a. Fix for gc type annotation
63    
64    5. MDGen
65    
66       Various fixes for machine description -> ml code translation.  For ssa
67       only.

73    Description:
74    
75      Fermin has found a few assembly problems with constant expressions
76      generated in LabelExp.  Mostly, the problems involve extra parentheses,
77      which choke on dumb assemblers.  This is his fix.

83    Description:
84    
85    1. Updated src/compiler/TopLevel/main/version.sml to version 110.28
86    
87    2. Updated config/version to 110.28
88    
89    3. Updated config/srcarchiveurl
90    
91    3. New boot files!

97    Tag: blume-20000501-noweb
98    Description:
99    
100    A new noweb tool has been added.  The existing system is entirely
101    unaffected by this, but some CM users have asked for renewed noweb
102    support.  Everything is documented in the CM manual.
103    
104    New (plugin) libraries:
105    
106       noweb-tool.cm
107       nw-ext.cm

113    Description:
114    
115    1. Fix for bug 1498
116       smlnj/src/system/Basis/Implementation/Unsafe/object.sig
117       smlnj/src/system/Basis/Implementation/Unsafe/object.sml
118         added toRealArray function
119       smlnj/src/compiler/MiscUtil/print/ppobj.sml
120         added check for tag Obj.RealArray to array printing case in ppObj
121    
122    2. Fix for bug 1510
123       smlnj/src/compiler/Semant/types/typesutil.sml
124         fixed definition of dummyargs (used by equalTycon) so that
125         dummy args are distinct types

131    Description:
132    
133    1. CM version numbering added.  This is an implementation of Lal's
134       proposal for adding version numbers and version checking to .cm
135       files.  Lal said that his proposal was just that -- a proposal.
136       For the time being I went ahead and implemented it so that people
137       can comment on it.  Everything is completely backward-compatible
138       (except for the stable library format, i.e., new bootfiles!).
139    
140       As usual, see the CM manual for details.
141    
142    2. An alternative syntax for anchored paths has been implemented.
143       Dave has recently voiced the same concerns that I had when I did
144       this, so there should be some support.  My take is that eventually
145       I will let support for the current syntax (where anchors are
146       "implicit") fade out in favor of the new, explicit syntax.
147       In order to be backward-compatible, both old and new syntax are
148       currently supported.
149    
150       Again, see the CM manual for details.
151    
152    3. Parallel make is trying to be slightly smarter:  When the master
153       process finds a "bottleneck", i.e., when there is only one
154       compilation unit that can be compiled and everybody else is
155       waiting on it, then it will simply compile it directly instead
156       of clumsily telling one of the slaves to do it.
157    
158    4. Support for "unsharing" added.  This is necessary in order to be
159       able to have two different versions of the same library running
160       at the same time (e.g., for trying out a new MLRISC while still
161       having the old MLRISC linked into the current compiler, etc.)
162       See the CM manual.
163    
164    5. Simple "makedepend" functionality added for generating Makefile
165       dependency information.  (This is rather crude at the moment.
166       Expect some changes here in the future.)
167    
168    6. ".fun" added as a recognized suffix for ML files. Also documented
169       explicitly in the manual that the fallback behavior (unknown suffix
170       -> ML file) is not an official feature!
171    
172    7. Small changes to the pickler for stable libraries.
173    
174    8. Several internal changes to CM (for cleanup/improvement).
175    
176    
177    !!!! NEW BINFILES !!!!

182    Tag: blume-20000428-pathconfig
183    Description:
184    
185    1. I changed config/install.sh to remove duplicate entries from the
186       lib/pathconfig file at the end.  Moreover, the final version of
187       lib/pathconfig is sorted alphabetically.  The same (sorting) is done
188       in src/system/installml.
189    
190    2. The config/install.sh script now consistently uses relative
191       pathnames in lib/pathconfig whenever the anchor is in the lib
192       directory.  (So far this was true for the libraries that come
193       pre-compiled and bundled as part of the bootfiles but not for
194       libraries that are compiled by the script itself.)

201    
202    Added ".fun" as a recognized file name suffix (for ML code).
