Function core::arch::mips::__msa_hadd_s_w

pub unsafe fn __msa_hadd_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 Add

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