; Use an overaligned buffer to force base-pointer usage. Test verifies:
; - base pointer register (r30) is saved/defined/restored.
; - frame pointer register (r31) is saved/defined/restored.
; - stack frame is allocated with correct alignment.
; - Address of %AlignedBuffer is calculated based off offset from the stack
; pointer.
