[PATCH] D135733: AMDGPU: Treat asm as a hazard for all register read-after-write hazards

[Jay Foad via Phabricator via llvm-commits]

foad added a comment.

Could you detect empty inline asms and do this only for the non-empty ones? In graphics we use empty inline asms as some kind of scheduling barrier. (Granted this is just a workaround for problems elsewhere, but I don't really want it broken or penalised just now.)
