18    Description:
19    
20      Various bug fixes and new features for C--, Moby and MLRISC optimizations.
21    None of these affect SML/NJ.
22    
23    1. Register Allocation
24    
25        a. A new ra spilling module (ra/ra-spill-with-renaming) is implemented.
26           This module tries to remove local (i.e. basic block level) redundancies
27           during spilling.
28    
29        b. A new framework for performing region based register allocation.
30           Not yet entirely functional.
31    
32    2. X86
33    
34       a. DefUse for POP was missing the stack pointer [found by Lal]
35       b. Reload for CALL was incorrect in X86Spill [found by John]
36       c. Various fixes in X86Spill so that it can be used correctly for
37          the new spilling module.
38    
39    3. SSA/IR
40    
41       a. New module ir/dj-dataflow.sml implements elimination based
42          data flow analysis.
43    
44    4. MLRiscGen
45    
46       a. Fix for gc type annotation
47    
48    5. MDGen
49    
50       Various fixes for machine description -> ml code translation.  For ssa
51       only.

57    Description:
58    
59      Fermin has found a few assembly problems with constant expressions
60      generated in LabelExp.  Mostly, the problems involve extra parentheses,
61      which choke on dumb assemblers.  This is his fix.

82    Description:
83    
84    A new noweb tool has been added.  The existing system is entirely
85    unaffected by this, but some CM users have asked for renewed noweb
86    support.  Everything is documented in the CM manual.

88    New (plugin) libraries:
89    
90       noweb-tool.cm
