The aarch64 port is generating constrained unpredictable instructions.
These are being generated for the STRX instructiion
STRX Rs, Rt, [Rn]
where Rs == Rt.
and also LDAXP instructions
LDAXP Rt1, Rt2, [Rn]
where Rt1 == Rt2.
Both of these are defined as constrained unpredictable and do in fact generate illegal instructions on one of our partners implementations.
