Ng Zhi An a5d45862e6 [wasm-simd][arm64] Optimize f32x4 dup + mul into fmul by element ... Wasm SIMD does not have an opcode to multiply a vector by a scalar. In these cases, Wasm code uses mul(x, shuffle(y, imms)), where the shuffle is a dup of a single lane in y. Pattern match on this to emit a fmul (element). We can do similar pattern match on f64x2 too, that will come in a future patch.
