Subject: R600/SI: Update concat_vectors.ll to check for scratch usage
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=f1ba587963e92268a6d4b56a596b3a4a7e028aeb;p=oota-llvm.git

R600/SI: Update concat_vectors.ll to check for scratch usage

These tests were using SI-NOT: MOVREL to make sure concat vectors
weren't being lowered to stack loads and stores, but we are using
scratch buffers for the stack now instead of registers, so we need
to add an additional SI-NOT check for scratch buffers.

With this change I was able to uncover one broken test which will
be fixed in a future commit.
