36    Description:
37    
38    1. CM version numbering added.  This is an implementation of Lal's
39       proposal for adding version numbers and version checking to .cm
40       files.  Lal said that his proposal was just that -- a proposal.
41       For the time being I went ahead and implemented it so that people
42       can comment on it.  Everything is completely backward-compatible
43       (except for the stable library format, i.e., new bootfiles!).
44    
45       As usual, see the CM manual for details.
46    
47    2. An alternative syntax for anchored paths has been implemented.
48       Dave has recently voiced the same concerns that I had when I did
49       this, so there should be some support.  My take is that eventually
50       I will let support for the current syntax (where anchors are
51       "implicit") fade out in favor of the new, explicit syntax.
52       In order to be backward-compatible, both old and new syntax are
53       currently supported.
54    
55       Again, see the CM manual for details.
56    
57    3. Parallel make is trying to be slightly smarter:  When the master
58       process finds a "bottleneck", i.e., when there is only one
59       compilation unit that can be compiled and everybody else is
60       waiting on it, then it will simply compile it directly instead
61       of clumsily telling one of the slaves to do it.
62    
63    4. Support for "unsharing" added.  This is necessary in order to be
64       able to have two different versions of the same library running
65       at the same time (e.g., for trying out a new MLRISC while still
66       having the old MLRISC linked into the current compiler, etc.)
67       See the CM manual.
68    
69    5. Simple "makedepend" functionality added for generating Makefile
70       dependency information.  (This is rather crude at the moment.
71       Expect some changes here in the future.)
72    
73    6. ".fun" added as a recognized suffix for ML files. Also documented
74       explicitly in the manual that the fallback behavior (unknown suffix
75       -> ML file) is not an official feature!
76    
77    7. Small changes to the pickler for stable libraries.
78    
79    8. Several internal changes to CM (for cleanup/improvement).
80    
81    
82    !!!! NEW BINFILES !!!!

87    Tag: blume-20000428-pathconfig
88    Description:
89    
90    1. I changed config/install.sh to remove duplicate entries from the
91       lib/pathconfig file at the end.  Moreover, the final version of
92       lib/pathconfig is sorted alphabetically.  The same (sorting) is done
93       in src/system/installml.
94    
95    2. The config/install.sh script now consistently uses relative
96       pathnames in lib/pathconfig whenever the anchor is in the lib
97       directory.  (So far this was true for the libraries that come
98       pre-compiled and bundled as part of the bootfiles but not for
99       libraries that are compiled by the script itself.)

106    
107    Added ".fun" as a recognized file name suffix (for ML code).

114    
115    1. Alpha
116    
117        PSEUDOARITH was missing in AlphaRewrite.  This causes an endless loop
118    in C--.
119    
120    2. RA
121    
122       Added a flag "ra-dump-size" to print out the size of the flowgraph
123       and the interference graph.
