19    
20      Fermin has found a few assembly problems with constant expressions
21      generated in LabelExp.  Mostly, the problems involve extra parentheses,
22      which choke on dumb assemblers.  This is his fix.

43    Description:
44    
45    A new noweb tool has been added.  The existing system is entirely
46    unaffected by this, but some CM users have asked for renewed noweb
47    support.  Everything is documented in the CM manual.
48    
49    New (plugin) libraries:
50    
51       noweb-tool.cm
52       nw-ext.cm

75    Tag: blume-20000430-versions
76    Description:
77    
78    1. CM version numbering added.  This is an implementation of Lal's
79       proposal for adding version numbers and version checking to .cm
80       files.  Lal said that his proposal was just that -- a proposal.
81       For the time being I went ahead and implemented it so that people
82       can comment on it.  Everything is completely backward-compatible
83       (except for the stable library format, i.e., new bootfiles!).
84    
85       As usual, see the CM manual for details.
86    
87    2. An alternative syntax for anchored paths has been implemented.
88       Dave has recently voiced the same concerns that I had when I did
89       this, so there should be some support.  My take is that eventually
90       I will let support for the current syntax (where anchors are
91       "implicit") fade out in favor of the new, explicit syntax.
92       In order to be backward-compatible, both old and new syntax are
93       currently supported.
94    
95       Again, see the CM manual for details.
96    
97    3. Parallel make is trying to be slightly smarter:  When the master
98       process finds a "bottleneck", i.e., when there is only one
99       compilation unit that can be compiled and everybody else is
100       waiting on it, then it will simply compile it directly instead
101       of clumsily telling one of the slaves to do it.
102    
103    4. Support for "unsharing" added.  This is necessary in order to be
104       able to have two different versions of the same library running
105       at the same time (e.g., for trying out a new MLRISC while still
106       having the old MLRISC linked into the current compiler, etc.)
107       See the CM manual.
108    
109    5. Simple "makedepend" functionality added for generating Makefile
110       dependency information.  (This is rather crude at the moment.
111       Expect some changes here in the future.)
112    
113    6. ".fun" added as a recognized suffix for ML files. Also documented
114       explicitly in the manual that the fallback behavior (unknown suffix
115       -> ML file) is not an official feature!
116    
117    7. Small changes to the pickler for stable libraries.
118    
119    8. Several internal changes to CM (for cleanup/improvement).
120    
121    
122    !!!! NEW BINFILES !!!!

127    Tag: blume-20000428-pathconfig
128    Description:
129    
130    1. I changed config/install.sh to remove duplicate entries from the
131       lib/pathconfig file at the end.  Moreover, the final version of
132       lib/pathconfig is sorted alphabetically.  The same (sorting) is done
133       in src/system/installml.
134    
135    2. The config/install.sh script now consistently uses relative
136       pathnames in lib/pathconfig whenever the anchor is in the lib
137       directory.  (So far this was true for the libraries that come
138       pre-compiled and bundled as part of the bootfiles but not for
139       libraries that are compiled by the script itself.)

153    Description:
154    
155    1. Alpha
156    
157        PSEUDOARITH was missing in AlphaRewrite.  This causes an endless loop
158    in C--.
159    
160    2. RA
161    
162       Added a flag "ra-dump-size" to print out the size of the flowgraph
163       and the interference graph.

169    Description:
170      Updated mlyacc.tex sections 5 and 7 for SML '97 and CM.
171      Updated all three examples in src/ml-yacc/examples to run
172      under 110.* using CM.make.

177    Tag: leunga-20000420-ssa-c---stuff
178    Description:
179    
180      This update synchronizes my repository with Yale's.  Most of these
181    changes, however, do not affect SML/NJ at all (the RA is an exception).
182    
183    1. Register Allocator
184    
185       a. An improvement in the interference graph construction:
186          Given a copy
187    
188                s <- t
189    
190          no interference edge between s and t is added for this definition of s.
191    
192       b. I've added two new spill heuristic modules that Fermin and I developed
193          (in the new library RA.cm). These are unused in SML/NJ but maybe
194          useful for others (Moby?)
195    
196    2. X86
197    
198       a. Various fixes in the backend provided by Fermin [C--] and Lal.
199    
200    3. Alpha
201    
202       a. Added the BSR instruction and code generation that goes with it [C--]
203       b. Other fixes too numerous to recount provided by Fermin [C--]
204    
205    4. Regmaps
206    
207       a. The regmaps are not initialized with the identity physical bindings
208          at creation time.  This is unneeded.
209    
210    5. MLRISC Optimizations
211    
212       a. The DJ-Graph module can now compute the iterated dominance frontiers
213          intersects with liveness incrementally in linear time! Woohoo!
214          This is now used in my new SSA construction algorithm.
215    
216       b. THe branch reorganization module is now smarter about linear chains of
217          basic blocks.

224    Description:
225    
226    Changed install.sh script to handle archive files without version number
227    and to use "boot.<arch>-<os>" instead of "sml.boot.<arch>-<os>" for the
228    name of the boot file archive.

256    Description:
257    
258    Improved handling of branches (mostly those generated from
259    polymorphic equality), removed switchoff and changed the
260    default optimization settings (more cpsopt and less flintopt).
