PMLAL

Multi-vector polynomial multiply long and accumulate

This instruction performs a polynomial multiplication over [0, 1] of the even-numbered elements of the first source vector by the corresponding elements of the second source vector, and then performs a bitwise exclusive-OR between the result and the overlapping double-width elements of the first destination vector. The same operation is performed with odd-numbered elements of the source vectors, writing to the second destination vector. This instruction is unpredicated.

This instruction is legal when executed in Streaming SVE mode if both FEAT_SSVE_AES and FEAT_SVE_AES2 are implemented.
