21 * "Generic" vectors. All operands are given as offsets from ENV,
22 * and therefore cannot also be allocated via tcg_global_mem_new_*.
23 * OPRSZ is the byte size of the vector upon which the operation is performed.
24 * MAXSZ is the byte size of the full vector; bytes beyond OPSZ are cleared.
25 *
26 * All sizes must be 8 or any multiple of 16.
27 * When OPRSZ is 8, the alignment may be 8, otherwise must be 16.
28 * Operands may completely, but not partially, overlap.
