Function core::arch::arm::shsub16

pub unsafe fn shsub16(a: int16x2_t, b: int16x2_t) -> int16x2_t

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

This is supported on ARM only.

Signed halving parallel halfword-wise subtraction.

Returns the 16-bit signed equivalent of

res[0] = (a[0] - b[0]) / 2 res[1] = (a[1] - b[1]) / 2
