I haven't looked at the new branch yet, so forgive me if this is obvious
or handled already. In my attempt I found that the only way to handle
multi-word registers well was to really track (and allocate) partially
live registers, i.e. separate words in a whole multi-word web. That was
what the whole subweb mess was coming from, which was slowing down the
whole allocator quite a bit.
Ciao,
Michael.
