19      Moby, C--, SSA, x86, machine descriptions etc.  Should only affect C--
20    and Mobdy.
21    
22    1.  x86
23    
24       a.  Fixes to peephole module by John and Dan.
25       b.  Assembly fix to SETcc by Allen.
26       c.  Fix to c-call by John.
27       d.  Fix to spilling by John.  (This one deals with the missing FSTPT case)
28       e.  Instruction selection optimization to SETcc as suggested by John.
29    
30           For example,
31    
32            MV(32, x, COND(32, CMP(32, LT, a, b), LI 1, LI 0))
33    
34           should generate:
35    
36            MOVL a, x
37            SUBL b, x
38            SHRL 31, x
39    
40    2.  IR stuff
41    
42         A bunch of new DJ-graph related algorithms added.  These
43         speed up SSA construction.
44    
45    3.  SSA + Scheduling
46    
47         Added code for SSA and scheduling to the repository
