[−][src]Function core::arch::wasm32::v8x16_shuffle
pub unsafe fn v8x16_shuffle<const I0: usize, const I1: usize, const I2: usize, const I3: usize, const I4: usize, const I5: usize, const I6: usize, const I7: usize, const I8: usize, const I9: usize, const I10: usize, const I11: usize, const I12: usize, const I13: usize, const I14: usize, const I15: usize>(
a: v128,
b: v128
) -> v128
This is supported on WebAssembly and target feature
simd128 only.Returns a new vector with lanes selected from the lanes of the two input
vectors $a and $b specified in the 16 immediate operands.
The $a and $b expressions must have type v128, and this macro
generates a wasm instruction that is encoded with 16 bytes providing the
indices of the elements to return. The indices i in range [0, 15] select
the i-th element of a. The indices in range [16, 31] select the i - 16-th element of b.
Note that this is a macro due to the codegen requirements of all of the
index expressions $i* must be constant. A compiler error will be
generated if any of the expressions are not constant.
All indexes $i* must have the type u32.
