Vectorised Integer results, when Rc=1, will begin writing to CR8 (TBD evaluate) and increase sequentially from there. Vectorised FP results, when Rc=1, start from CR32 (TBD evaluate). This is so that: -* implementations may rely on the Vector CRs being aligned to 8. This means that CRs may be read or written in aligned batches of 32 bits, for high performance implementations. +* implementations may rely on the Vector CRs being aligned to 8.
