[PATCH] D131959: [AMDGPU] Fix SDST operand of V_DIV_SCALE to always be VCC

[Jay Foad via Phabricator via llvm-commits]

foad added a comment.

I think if you fix the COPY to refer to $vcc_lo instead of $vcc (for wave 32) then SILowerI1Copies will be happy, because $vcc_lo will satisfy the isLaneMaskReg test. But there should be no need to change the regclass of the COPY.
