[llvm-commits] We are selecting a CMP64mi32 instead of a CMP64mi8

[Rafael Espindola]

I am debugging a case where llc + llvm-mc produces different results
from using "llc -filetype=obj". The issues is that for the attached
test llc selects CMP64mi32. This prints as

cmpq	$0, -8(%rsp)

Which gets parsed by llvm-mc as the 8 bit immediate version. Why are
we selecting CMP64mi32? The attached patch fixes this particular
issue, but it would be better if we could this in a less brittle way.

Cheers,
