-mcpu= takes precedence over -arch; however, the slice (cpu subtype in the MachO file) is still dictated by the -arch setting only.

Using -march= and -mcpu= at the same time should probably be a hard error. -march is preferable and 32-bit ARM is the outlier for historical reasons in preferring -mcpu. I’d love to be able to change that, but it’s likely to be a hard road.
