18    Description:
19    
20    The main change is that I added function CM.sources as a generalized
21    version of the earlier CM.makedepend.  This entails the following
22    additional changes:
23    
24      - CM.makedepend has been dropped.
25    
26      - CM manual has been updated.
27    
28      - TOOLS signature and API have been changed.

34    Description:
35    
36      Various bug fixes and new features for C--, Moby and MLRISC optimizations.
37    None of these affect SML/NJ.
38    
39    1. Register Allocation
40    
41        a. A new ra spilling module (ra/ra-spill-with-renaming) is implemented.
42           This module tries to remove local (i.e. basic block level) redundancies
43           during spilling.
44    
45        b. A new framework for performing region based register allocation.
46           Not yet entirely functional.
47    
48    2. X86
49    
50       a. DefUse for POP was missing the stack pointer [found by Lal]
51       b. Reload for CALL was incorrect in X86Spill [found by John]
52       c. Various fixes in X86Spill so that it can be used correctly for
53          the new spilling module.
54    
55    3. SSA/IR
56    
57       a. New module ir/dj-dataflow.sml implements elimination based
58          data flow analysis.
59    
60    4. MLRiscGen
61    
62       a. Fix for gc type annotation
63    
64    5. MDGen
65    
66       Various fixes for machine description -> ml code translation.  For ssa
67       only.
