Function core::arch::mips::__msa_dpadd_s_d

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

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

This is supported on MIPS and target feature msa only.

Vector Signed Dot Product and Add

The signed integer elements in vector 'b' (four signed 32-bit integer numbers) are multiplied by signed integer elements in vector 'c' (four signed 32-bit integer numbers). producing a result twice the size of the input operands. The multiplication results of adjacent odd/even elements are added to the vector 'a' (two signed 64-bit integer numbers).
