Function safe_arch::abs_i8_m128i

#[must_use]pub fn abs_i8_m128i(a: m128i) -> m128i

This is supported with target feature ssse3 only.

Lanewise absolute value with lanes as i8.

This is a "wrapping" absolute value, so i8::MIN stays as i8::MIN.

let a = m128i::from([
  0_i8, -1, 2, -3, 4, -5, 6, -7, -8, 9, -10, 11, -12, 13, -14, -128,
]);
let c: [i8; 16] = abs_i8_m128i(a).into();
assert_eq!(c, [0_i8, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, -128]);
