Whether by accident or intention you picked a lot of stuff having to
do with register classes,
Accident: I was going sequentially through alpha.h.
Wasn't Michael Matz just saying that regclass.c needed a major rework
anyway, or the new register allocator would never be able to replace
the old? I don't know what his design looks like, or even if he has
one yet, but surely there is a simpler way to structure this, that
doesn't involve lots of little tiny macros.
I don't see what that has to do with the specification of classes, which
are attributes of the machine. Those macros are used by far more than
just regclass.c and the register allocator ...
