Function core::arch::arm::__smlsd

pub unsafe fn __smlsd(a: int16x2_t, b: int16x2_t, c: i32) -> i32

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

This is supported on ARM only.

Dual 16-bit Signed Multiply with Subtraction of products and 32-bit accumulation and overflow detection.

Returns the 16-bit signed equivalent of res = a[0] * b[0] - a[1] * b[1] + c
