; This file does not contain many test cases involving comparisons and logical
; comparisons (cmplwi, cmpldi). This is because alternative code is generated
; when there is a compare (logical or not), followed by a sign or zero extend.
; This codegen will be re-evaluated at a later time on whether or not it should
; be emitted on P10.
