"message": "SVE and the first version of SME do not have an LDP equivalent instruction. SVE 2.1 and SME 2 introduce multi-vector load/store instructions which are equivalent to LDP/STP however these would need additional compiler features to be enabled (-march\u003d...+sme2 rather than -march\u003d...+sme which we currently use).\n\nOf course if you can guarantee that the vector length is 128 bits then you can use the Neon LDP/STP instructions since they share the same vector length, but this is not portable so I would prefer to avoid hard-coding this anywhere.",
