; CHECK that this program is correctly code generated and does not result in
; 'instruction does not dominate use' errors. At an earlier point, such errors
; have been generated as the preparation of the managed memory pointers was
; performed right before kernel0, which does not dominate all other kernels.
; Now the preparation is performed at the very beginning of the scop.
