! X86: Target: x86_64-unknown-linux-gnu

! The footer displayed contains a reference to clang. This should be changed to
! flang, but that requires a change in llvm/MCSubtargetInfo. When that happens,
! this test will need to be updated and this comment can be removed.

! CHECK: Use -mcpu or -mtune to specify the target's processor.
! CHECK: For example, clang --target=aarch64-unknown-linux-gnu
