; Check that all the offsets in the .cfi_offset instructions are negative.
; They are all based on R30+8 which points to the pair FP/LR stored by an
; allocframe. Since the stack grows towards negative addresses, anything
; in the current stack frame will have a negative offset with respect to
; R30+8.
