Function core::arch::mips::__msa_hsub_s_w

pub unsafe fn __msa_hsub_s_w(a: v8i16, b: v8i16) -> v4i32

🔬 This is a nightly-only experimental API. (stdsimd #48556)

This is supported on MIPS and target feature msa only.

Vector Signed Horizontal Subtract

The sign-extended odd elements in vector b (eight signed 16-bit integer numbers) are subtracted from the sign-extended elements in vector a (eight signed 16-bit integer numbers) producing a result twice the size of the input operands. The result is written to vector (four signed 32-bit integer numbers).
