Netlib BLAS is a very low bar [1], and not at all how one should go about writing a performance portable BLAS. BLIS (https://github.com/flame/blis/ https://github.com/flame/blis/) is a much better approach, and underlies vendor implementations on AMD (https://developer.amd.com/amd-aocl/blas-library/ https://developer.amd.com/amd-aocl/blas-library/) and many embedded systems. [1] GEMV is entirely limited by memory bandwidth, thus quite uninteresting from a vectorization standpoint. Maybe you meant GEMM?
