[−][src]Function core::arch::mips64::__msa_msub_q_w
pub unsafe fn __msa_msub_q_w(a: v4i32, b: v4i32, c: v4i32) -> v4i32
This is supported on MIPS-64 and target feature
msa only.Vector Fixed-Point Multiply and Subtract
The product of fixed-point elements in vector c (four signed 32-bit integer numbers)
by fixed-point elements in vector b (four signed 32-bit integer numbers)
are subtracted from 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 subtracted from the destination.
The saturated fixed-point results are stored back to vector a.
