[PATCH] D105709: [AMDGPU][GlobalISel] Insert an and with exec before s_cbranch_vccnz if necessary

[Mirko Brkusanin via Phabricator via llvm-commits]

mbrkusanin added a comment.

Alternatively we could always insert and with exec and try to remove it in SIOptimizeExecMaskingPreRA (something similar to optimizeVcndVcmpPair).
