; RUN: llc < %s -march=avr | FileCheck %s

; This test ensures that the backend can lower returns of struct values.
; It does not check how these are lowered.
;
; In the past, this code used to return an error
;
; Assertion `InVals.size() == Ins.size() && "LowerFormalArguments didn't emit the correct number of values!"' failed.
;
; This feature was first implemented in r325474.
