|

; Test LinearFunctionTestReplace of a pointer-type loop counter. Note
|

; that BECount may or may not be a pointer type. A pointer type
|
|
; BECount doesn't really make sense, but that's what falls out of
|
|
; SCEV. Since it's an i8*, it has unit stride so we never adjust the
|
|
; SCEV expression in a way that would convert it to an integer type.
