llvm/test/Bitcode/upgrade-arc-runtime-calls.ll

; Test that calls to ARC runtime functions are converted to intrinsic calls if
; the bitcode has the arm64 retainAutoreleasedReturnValueMarker metadata.

; upgrade-arc-runtime-calls.bc and upgrade-mrr-runtime-calls.bc are identical
; except that the former has the arm64 retainAutoreleasedReturnValueMarker
; metadata. upgrade-arc-runtime-calls-new.bc has the new module flag format of
; marker, it should not be upgraded.
