core::arch::mips::__msa_msub_q_w - Rust
Description: API documentation for the Rust `__msa_msub_q_w` fn in crate `core`.
Keywords: rust, rustlang, rust-lang, __msa_msub_q_w

# [−][src]Function core::arch::mips::__msa_msub_q_w

    pub unsafe fn __msa_msub_q_w(a: v4i32, b: v4i32, c: v4i32) -> v4i32

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on MIPS 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`.
