[ x4.patch ]
The register allocator seems to do a great jub. It does e.g. color a diamond-like interference graph correctly with two colors only:
x
/ \
w z
\ /
y(the lines denote an interference - BTW you might create some PIR could that has exactly this interference graph - not quite easy). The old allocator took three colors.
Anyway: are there already numbers from the big evil subs?
