; REQUIRES: asserts
;
; This test used to crash with the following assertion:
; llc: include/llvm/ADT/IntervalMap.h:632: unsigned int llvm::IntervalMapImpl::LeafNode<llvm::SlotIndex, llvm::LiveInterval *, 8, llvm::IntervalMapInfo<llvm::SlotIndex> >::insertFrom(unsigned int &, unsigned int, KeyT, KeyT, ValT) [KeyT = llvm::SlotIndex, ValT = llvm::LiveInterval *, N = 8, Traits = llvm::IntervalMapInfo<llvm::SlotIndex>]: Assertion `(i == Size || Traits::stopLess(b, start(i))) && "Overlapping insert"' failed.
;
; This was related to incorrectly calculating subregister live ranges
; (i.e. live interval subranges): subregister defs are not uses for that
; purpose.
;
; Check for a valid output.
; CHECK: image_sample_c
