pub fn u8x16_relaxed_swizzle(a: v128, s: v128) -> v128🔬This is a nightly-only experimental API. (
simd_wasm64 #90599)Available on
target_family="wasm" and target feature relaxed-simd and WebAssembly only.Expand description
A relaxed version of i8x16_swizzle(a, s) which selects lanes from a
using indices in s.
Indices in the range [0,15] will select the i-th element of a.
If the high bit of any element of s is set (meaning 128 or greater) then
the corresponding output lane is guaranteed to be zero. Otherwise if the
element of s is within the range [16,128) then the output lane is either
0 or a[s[i] % 16] depending on the implementation.
