[PATCH] D109300: [AMDGPU] Make vector superclasses allocatable

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec added a comment.

I have just applied the patch and verified there are no live AV operands after selection and basically anywhere. So I guess that clears the concerns of how RA would select an actual RC - it would not. This is what we need I suppose.
I am still unclear about PSet though. Maybe it is better to suppress PSet generation?
