<div>
<pre>Given
define <4 x float> @sin_4x32(<4 x float> %a) {
%b = tail call <4 x float> @llvm.sin.v4f32(<4 x float> %a)
ret <4 x float> %b
}
declare <4 x float> @llvm.sin.v4f32(<4 x float>)
this always produces a sequence of 4 libm sinf calls when calling opt and/or
llc with -vector-library=SVML .
Instead, this should just lower to a call to the appropriate SVML (or
accelerate, libmvec, ...) instruction instead.</pre>
