19    Description:
20    
21    Major MLRISC internal changes.  Affect all clients.
22    Summary:
23    
24    1.  Type CELLS.cell = int is now replaced by a datatype.
25        As a result, the old regmap is now gone.  Almost all interfaces
26        in MLRISC change as a consequence.
27    
28    2.  A new brand version of machine description tool (v3.0) that generates
29        modules expecting the new interface.  The old version is removed.
30    
31    3.  The RA interface has been further abstracted into two new functors.
32        RISC_RA and X86RA.  These functors have much simpler interfaces.
33        [See also directory MLRISC/demo.]
34    
35    4.  Some other new source->source code generation tools are available:
36    
37        a. MLRISC/Tools/RewriteGen -- generate rewriters from rules.
38        b. MLRISC/Tools/WhereGen -- expands conditional pattern matching rules.
39           I use this tool to generate the peephole optimizers---with the new
40           cell type changes, peephole rules are becoming difficult to write
41           without conditional pattern matching.
42    
43    5.  More Intmap -> IntHashTable change.  Previous changes by Matthias didn't
44        cover the entire MLRISC source tree so many things broke.
45    
46    6.  CM files have been moved to the subdirectory MLRISC/cm.
47        They are moved because there are a lot of them and they clutter up the
48        root dir.
49    
50    7.  More detailed documentation to come...
51    
52        NOTE: To rebuild from 110.30 (ftp distribution), you'll have to do
53        a makeml -rebuild first.  This is because of other other
54        changes that Matthias has made (see below).
