; This test lures sretpromotion into promoting the sret argument of foo, even
|
|
; when the function is used as an argument to bar. It used to not check for
|
|
; this, assuming that all users of foo were direct calls, resulting in an
|
|
; assertion failure later on.

; We're mainly testing for opt not to crash, but we'll check to see if the sret
|
|
; attribute is still there for good measure.
