<pre>This doesn't generate STP, but it seems like it should:
target datalayout = "e-m:o-i64:64-i128:128-n32:64-S128"
define float* @foo(float* nocapture %PTR, <4 x float> %VAL1, <4 x float> %VAL2)
{
entry:
%add.ptr = getelementptr inbounds float, float* %PTR, i64 -4
%tmp = bitcast float* %add.ptr to <4 x float>*
store <4 x float> %VAL1, <4 x float>* %tmp, align 16
%tmp1 = bitcast float* %PTR to <4 x float>*
store <4 x float> %VAL2, <4 x float>* %tmp1, align 16
%add.ptr2 = getelementptr inbounds float, float* %PTR, i64 8
ret float* %add.ptr2
}</pre>
