Suppose you're writing the backend for a VM supporting two architectures, in
which
one of them clobbers the CC registers for certain instructions, while the other
does not.
The instructions themselves are exactly the same.
What is the best/shortest/more-elegant way to write this, possibly w/out
duplicating the
instructions?
I know I can write a define_expand and redirect, based on the TARGET, to two
different
instructions (one with "clobber", the other w/out), but that's basically three
declarations
for each insns. Is there a shorter way?
