21      Slight improvements to the 'nowhere' tool to handle OR-patterns,
22    to generate better error messages etc.  Plus a brief manual.

35    Description:
36    
37    Major MLRISC internal changes.  Affect all clients.
38    Summary:
39    
40    1.  Type CELLS.cell = int is now replaced by a datatype.
41        As a result, the old regmap is now gone.  Almost all interfaces
42        in MLRISC change as a consequence.
43    
44    2.  A new brand version of machine description tool (v3.0) that generates
45        modules expecting the new interface.  The old version is removed.
46    
47    3.  The RA interface has been further abstracted into two new functors.
48        RISC_RA and X86RA.  These functors have much simpler interfaces.
49        [See also directory MLRISC/demo.]
50    
51    4.  Some other new source->source code generation tools are available:
52    
53        a. MLRISC/Tools/RewriteGen -- generate rewriters from rules.
54        b. MLRISC/Tools/WhereGen -- expands conditional pattern matching rules.
55           I use this tool to generate the peephole optimizers---with the new
56           cell type changes, peephole rules are becoming difficult to write
57           without conditional pattern matching.
58    
59    5.  More Intmap -> IntHashTable change.  Previous changes by Matthias didn't
60        cover the entire MLRISC source tree so many things broke.
61    
62    6.  CM files have been moved to the subdirectory MLRISC/cm.
63        They are moved because there are a lot of them and they clutter up the
64        root dir.
65    
66    7.  More detailed documentation to come...
67    
68        NOTE: To rebuild from 110.30 (ftp distribution), you'll have to do
69        a makeml -rebuild first.  This is because of other other
70        changes that Matthias has made (see below).

85    Description:
86    
87    Drastically improved link traversal code for the case that the dynamic
88    value was already loaded at bootstrap time.  As a result, CM and CMB
89    now both load blazingly fast -- even on a very slow machine.  Also,
90    memory consumption has been further reduced by this.
91    
92    Warning: The format of the PIDMAP file has changed.  THerefore, to
93    bootstrap you have to do this:
94    
95    1. Run CMB.make
96    2. Make a symbolic link for the boot directory:
97         ln -s sml.boot.ARCH-OS xxx
98    3. "Rebuild" the boot directory:
99         ./makeml -boot xxx -rebuild sml ; rm xxx
100    4. Boot normally:
101          ./makeml
