[−][src]Function core::arch::mips::__msa_msubr_q_w
pub unsafe fn __msa_msubr_q_w(a: v4i32, b: v4i32, c: v4i32) -> v4i32
This is supported on MIPS and target feature
msa only.Vector Fixed-Point Multiply and Subtract Rounded
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 rounded and saturated fixed-point results are stored back to vector a.
