; The dominance of the generated non-affine subregion block was based on the
|

|
|
; scop's merge block, therefore resulted in an invalid DominanceTree.

|
; It resulted in some values as assumed to be unusable in the actual generated
|
||
|
|
; exit block. Here we check whether the value %escaping is taken from the

; generated block.
