I might misunderstand your question, but the vector modes that are supported are enumerated by the port. See e.g. gcc/config/i386/i386-modes.def, the VECTOR_MODE lines. With that done, the machine description defines the standard-name-patterns for vector insns that apply to the port (which includes those modes as part of the names, as mentioned). brgds, H-P
