Available on (MIPS or MIPS-64) and target feature msa and MIPS-64 only.

Vector Signed Horizontal Add

The sign-extended odd elements in vector a (four signed 32-bit integer numbers) are added to the sign-extended even elements in vector b (four signed 32-bit integer numbers) producing a result twice the size of the input operands. The result is written to vector (two signed 64-bit integer numbers).
