Function safe_arch::sign_apply_i8_m128i

#[must_use]pub fn sign_apply_i8_m128i(a: m128i, b: m128i) -> m128i

This is supported with target feature ssse3 only.

Applies the sign of i8 values in b to the values in a.

• If b is negative: the a value is negated.
• Else If b is 0: the a value becomes 0.
• Else the a value is unchanged.

let a =
  m128i::from([0_i8, 1, -2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, -15]);
let b = m128i::from([-1_i8, 1, 1, -1, -1, 1, 1, 1, 1, 0, 0, -1, -1, 0, 0, 1]);
let c: [i8; 16] = sign_apply_i8_m128i(a, b).into();
assert_eq!(c, [0_i8, 1, -2, -3, -4, 5, 6, 7, 8, 0, 0, -11, -12, 0, 0, -15]);
