[LLVMdev] Sparc: handling unused operands in instruction format F3_3
...ompare ignores rd because it only sets
flags). Sadly, this confuses TableGen, which doesn't know how to fill
the "remaining" registers, and segfaults due to complications from an
out-of-bounds array access.
How am I to handle this? I thought about creating subclasses of F3_3
(such as F3_3unary or F3_3nodest) and therein explicitly assigning
values to the ignored registers (to prevent TableGen from trying and
failing to populate them), but I don't know if this is the Right Thing
to do.
