source · pub fn i64x2_relaxed_laneselect(a: v128, b: v128, m: v128) -> v128
🔬This is a nightly-only experimental API. (
stdsimd
#48556)Available on
target_family="wasm"
and target feature relaxed-simd
and WebAssembly only.Expand description
A relaxed version of v128_bitselect
where this either behaves the same as
v128_bitselect
or the high bit of each lane m
is inspected and the
corresponding lane of a
is chosen if the bit is 1 or the lane of b
is
chosen if it’s zero.
If the m
mask’s lanes are either all-one or all-zero then this instruction
is the same as v128_bitselect
.
