| ; 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: opt < %s -sretpromotion -S | grep sret |

| %struct.S = type <{ i32, i32 }> |

| define i32 @main() { |
| entry: |
| %bar = bitcast void (%struct.S*)* @foo to i32 ()* |
| ret i32 undef |
