18    Description:
19      Updated mlyacc.tex sections 5 and 7 for SML '97 and CM.
20      Updated all three examples in src/ml-yacc/examples to run
21      under 110.* using CM.make.

27    Description:
28    
29      This update synchronizes my repository with Yale's.  Most of these
30    changes, however, do not affect SML/NJ at all (the RA is an exception).
31    
32    1. Register Allocator
33    
34       a. An improvement in the interference graph construction:
35          Given a copy
36    
37                s <- t
38    
39          no interference edge between s and t are added for this definition of s.
40    
41       b. I've added two new spill heuristic modules that Fermin and I developed
42          (in the new library RA.cm). These are unused in SML/NJ but maybe
43          useful for others (Moby?)
44    
45    2. X86
46    
47       a. Various fixes in the backend provided by Fermin [C--] and Lal.
48    
49    3. Alpha
50    
51       a. Added the BSR instruction and code generation that goes with it [C--]
52       b. Other fixes too numerous to recount provided by Fermin [C--]
53    
54    4. Regmaps
55    
56       a. The regmaps are not initialized with the identity physical bindings
57          at creation time.  This is unneeded.
58    
59    5. MLRISC Optimizations
60    
61       a. The DJ-Graph module can now compute the iterated dominance frontiers
62          intersects with liveness incrementally in linear time! Woohoo!
63          This is now used in my new SSA construction algorithm.
64    
65       b. THe branch reorganization module is now smarter about linear chains of
66          basic blocks.
