[PATCH] D133169: [AMDGPU] Constrain src0 RC of 64 bit shift amount on gfx90a

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec added a comment.

Now the w/a in the hazard recognizer is submitted, do we need this as well? The w/a in the recognizer produces quite heavy code, this can reduce chances of it to minimum. Although this may also increase register pressure.
