; This test verifies whether optimization which allows to avoid additional control flow
; generation works per kernel. Below LLVM module implements two kernels:
; - kernelA - contains store instruction operating on generic pointer which always
; points to local memory. Additional controflow is required as local->generic
; cast was detected.
; - kernelB - contains store instruction operating on generic pointer which always
; point to global memory
