            Bug ID: 38528
           Summary: llvm.sin.v4f32 with -vector-library=SVML fails to
                    lower to SVM function call
           Product: new-bugs
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org

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.
