Function core::arch::arm::__shsub8

pub unsafe fn __shsub8(a: int8x4_t, b: int8x4_t) -> int8x4_t

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

Available on ARM only.

Signed halving parallel byte-wise subtraction.

Returns the 8-bit signed equivalent of

res[0] = (a[0] - b[0]) / 2 res[1] = (a[1] - b[1]) / 2 res[2] = (a[2] - b[2]) / 2 res[3] = (a[3] - b[3]) / 2
