; This test shows an sret function that is used as an operand to a bitcast.
; StructRetPromotion used to assume that a function was only used by call or
; invoke instructions, making this code cause an assertion failure.
; 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.
; RUN: llvm-as < %s | opt -sretpromotion | llvm-dis | grep sret
%struct.S = type <{ i32, i32 }>
