17    Tag: blume-20000430-versions
18    Description:
19    
20    1. CM version numbering added.  This is an implementation of Lal's
21       proposal for adding version numbers and version checking to .cm
22       files.  Lal said that his proposal was just that -- a proposal.
23       For the time being I went ahead and implemented it so that people
24       can comment on it.  Everything is completely backward-compatible
25       (except for the stable library format, i.e., new bootfiles!).
26    
27       As usual, see the CM manual for details.
28    
29    2. An alternative syntax for anchored paths has been implemented.
30       Dave has recently voiced the same concerns that I had when I did
31       this, so there should be some support.  My take is that eventually
32       I will let support for the current syntax (where anchors are
33       "implicit") fade out in favor of the new, explicit syntax.
34       In order to be backward-compatible, both old and new syntax are
35       currently supported.
36    
37       Again, see the CM manual for details.
38    
39    3. Parallel make is trying to be slightly smarter:  When the master
40       process finds a "bottleneck", i.e., when there is only one
41       compilation unit that can be compiled and everybody else is
42       waiting on it, then it will simply compile it directly instead
43       of clumsily telling one of the slaves to do it.
44    
45    4. Support for "unsharing" added.  This is necessary in order to be
46       able to have two different versions of the same library running
47       at the same time (e.g., for trying out a new MLRISC while still
48       having the old MLRISC linked into the current compiler, etc.)
49       See the CM manual.
50    
51    5. Simple "makedepend" functionality added for generating Makefile
52       dependency information.  (This is rather crude at the moment.
53       Expect some changes here in the future.)
54    
55    6. ".fun" added as a recognized suffix for ML files. Also documented
56       explicitly in the manual that the fallback behavior (unknown suffix
57       -> ML file) is not an official feature!
58    
59    7. Small changes to the pickler for stable libraries.
60    
61    8. Several internal changes to CM (for cleanup/improvement).
62    
63    
64    !!!! NEW BINFILES !!!!

69    Tag: blume-20000428-pathconfig
70    Description:
71    
72    1. I changed config/install.sh to remove duplicate entries from the
73       lib/pathconfig file at the end.  Moreover, the final version of
74       lib/pathconfig is sorted alphabetically.  The same (sorting) is done
75       in src/system/installml.
76    
77    2. The config/install.sh script now consistently uses relative
78       pathnames in lib/pathconfig whenever the anchor is in the lib
79       directory.  (So far this was true for the libraries that come
80       pre-compiled and bundled as part of the bootfiles but not for
81       libraries that are compiled by the script itself.)

87    Description:
88    
89    Added ".fun" as a recognized file name suffix (for ML code).

95    Description:
96    
97    1. Alpha
98    
99        PSEUDOARITH was missing in AlphaRewrite.  This causes an endless loop
100    in C--.
101    
102    2. RA
103    
104       Added a flag "ra-dump-size" to print out the size of the flowgraph
105       and the interference graph.

110    Tag: dbm-20000425-mlyacc_doc_examples
111    Description:
112      Updated mlyacc.tex sections 5 and 7 for SML '97 and CM.
113      Updated all three examples in src/ml-yacc/examples to run
114      under 110.* using CM.make.

120    Description:
121    
122      This update synchronizes my repository with Yale's.  Most of these
123    changes, however, do not affect SML/NJ at all (the RA is an exception).
124    
125    1. Register Allocator
126    
127       a. An improvement in the interference graph construction:
128          Given a copy
129    
130                s <- t
131    
132          no interference edge between s and t is added for this definition of s.
133    
134       b. I've added two new spill heuristic modules that Fermin and I developed
135          (in the new library RA.cm). These are unused in SML/NJ but maybe
136          useful for others (Moby?)
137    
138    2. X86
139    
140       a. Various fixes in the backend provided by Fermin [C--] and Lal.
141    
142    3. Alpha
143    
144       a. Added the BSR instruction and code generation that goes with it [C--]
145       b. Other fixes too numerous to recount provided by Fermin [C--]
146    
147    4. Regmaps
148    
149       a. The regmaps are not initialized with the identity physical bindings
150          at creation time.  This is unneeded.
151    
152    5. MLRISC Optimizations
153    
154       a. The DJ-Graph module can now compute the iterated dominance frontiers
155          intersects with liveness incrementally in linear time! Woohoo!
156          This is now used in my new SSA construction algorithm.
157    
158       b. THe branch reorganization module is now smarter about linear chains of
159          basic blocks.

165    Tag: blume_main_v110p27_1
166    Description:
167    
168    Changed install.sh script to handle archive files without version number
169    and to use "boot.<arch>-<os>" instead of "sml.boot.<arch>-<os>" for the
170    name of the boot file archive.
