           Product: libraries
           Version: 3.9
          Hardware: Other
                OS: All

The following bytes correspond to a valid ldaxr instruction with bits that
should be ignored set. It will not be produced by an assembler, but it should
be decoded as valid.

Bytes: f8 e3 4f 8
Expected: ldaxrb w24, [sp]
