[PATCH] D39040: AMDGPU: Fix creating invalid copy when adjusting dmask

[Alex Smith via Phabricator via llvm-commits]

aejsmith added a comment.

With this, when dmask = 0x2, we get "image_get_lod v[0:1], ...". Based on what Marek said, wouldn't it only be returning a single value to v0? What would v1 get set to?

In comparison, for image_sample with dmask = 0x2 I see only a single destination register specified. That's also what I see on the proprietary driver for image_get_lod.
