Available with target feature avx2 only.
Expand description

Loads the reference given and zeroes any i64 lanes not in the mask.

  • A lane is “in” the mask if that lane’s mask value is set in the high bit (aka “if the lane’s value is negative”).
let a = set_splat_i64_m128i(5);
let b = load_masked_i64_m128i(&a, m128i::from([0_i64, -1]));
assert_eq!(<[i64; 2]>::from(b), [0_i64, 5]);
