This is supported on MIPS and target feature msa only.

Vector Fixed-Point Multiply and Add

The products of fixed-point elements in b (four signed 32-bit integer numbers) by fixed-point elements in vector c (four signed 32-bit integer numbers) are added to the fixed-point elements in vector a (four signed 32-bit integer numbers). The multiplication result is not saturated, i.e. exact (-1) * (-1) = 1 is added to the destination. The saturated fixed-point results are stored to vector a.
