Function core::arch::mips64::__msa_hadd_s_d

pub unsafe fn __msa_hadd_s_d(a: v4i32, b: v4i32) -> v2i64

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

This is supported on MIPS-64 and target feature msa only.

Vector Signed Horizontal Add

The sign-extended odd elements in vector a (four signed 32-bit integer numbers) are added to the sign-extended even elements in vector b (four signed 32-bit integer numbers) producing a result twice the size of the input operands. The result is written to vector (two signed 64-bit integer numbers).
