# [−][src]Function core::arch::mips64::__msa_dpsub_s_d

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

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on MIPS-64 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 subtracted from the integer elements in vector `a` (two signed 64-bit integer numbers).
