25    Description:
26    
27    Major MLRISC internal changes.  Affect all clients.
28    Summary:
29    
30    1.  Type CELLS.cell = int is now replaced by a datatype.
31        As a result, the old regmap is now gone.  Almost all interfaces
32        in MLRISC change as a consequence.
33    
34    2.  A new brand version of machine description tool (v3.0) that generates
35        modules expecting the new interface.  The old version is removed.
36    
37    3.  The RA interface has been further abstracted into two new functors.
38        RISC_RA and X86RA.  These functors have much simpler interfaces.
39        [See also directory MLRISC/demo.]
40    
41    4.  Some other new source->source code generation tools are available:
42    
43        a. MLRISC/Tools/RewriteGen -- generate rewriters from rules.
44        b. MLRISC/Tools/WhereGen -- expands conditional pattern matching rules.
45           I use this tool to generate the peephole optimizers---with the new
46           cell type changes, peephole rules are becoming difficult to write
47           without conditional pattern matching.
48    
49    5.  More Intmap -> IntHashTable change.  Previous changes by Matthias didn't
50        cover the entire MLRISC source tree so many things broke.
51    
52    6.  CM files have been moved to the subdirectory MLRISC/cm.
53        They are moved because there are a lot of them and they clutter up the
54        root dir.
55    
56    7.  More detailed documentation to come...
57    
58        NOTE: To rebuild from 110.30 (ftp distribution), you'll have to do
59        a makeml -rebuild first.  This is because of other other
60        changes that Matthias has made (see below).

69    Some manual updates and some file reorganizations in CM.

74    Tag: blume-20001124-link
75    Description:
76    
77    Drastically improved link traversal code for the case that the dynamic
78    value was already loaded at bootstrap time.  As a result, CM and CMB
79    now both load blazingly fast -- even on a very slow machine.  Also,
80    memory consumption has been further reduced by this.
81    
82    Warning: The format of the PIDMAP file has changed.  THerefore, to
83    bootstrap you have to do this:
84    
85    1. Run CMB.make
86    2. Make a symbolic link for the boot directory:
87         ln -s sml.boot.ARCH-OS xxx
88    3. "Rebuild" the boot directory:
89         ./makeml -boot xxx -rebuild sml ; rm xxx
90    4. Boot normally:
91          ./makeml

98    
99    Continued hacking on autoloading problem -- with success this time.
100    Also changed tool-plugin mechanism.  See new CM manual.

106    Description:
107    
108    Some hacking to make autoloading faster.  Success for CMB, no success
109    so far for CM.  There is a reduced structure CM' that autoloads faster.
110    (This is a temporary, non-documented hack to be eliminated again when
111    the general problem is solved.)

116    Tag: blume-20001117-pickle-lib
117    Description:
118    
119    1. Eliminated comp-lib.cm
120    2. Made pickle-lib.cm
121    3. Eliminated all uses of intset.sml (from comp-lib.cm)
122    4. Replaced all uses of intmap.{sig,sml} (from comp-lib.cm) with
123       equivalent constructs from smlnj-lib.cm (INtHashTable).
124    5. Point 4. also goes for those uses of intmap.* in MLRISC.
125       Duplicated intmap modules thrown out.
126    6. Hunted down all duplicated SCC code and replaced it with
127       equivalent stuff (GraphSCCFn from smlnj-lib.cm).
128    7. Rewrote Feedback module.
129    8. Moved sortedlist.sml into viscomp-lib.cm.  Eventually it
130       should be thrown out and equivalent modules from smlnj-lib.cm
131       should be used (IntRedBlackSet, IntListSet, ...).
132    
133    Confirmed that compiler compiles to fixpoint.
