Comment (by ami_stuff):

 Uh, and here is a fix:


 ; float scalarproduct_float_sse(const float *v1, const float *v2, int len)
 cglobal scalarproduct_float_sse, 3,3,2, v1, v2, offset
     neg offsetq
     shl offsetq, 2
     sub v1q, offsetq
     sub v2q, offsetq
     xorps xmm0, xmm0
         movaps   xmm1, [v1q+offsetq]
         mulps    xmm1, [v2q+offsetq]
         addps    xmm0, xmm1
         add      offsetq, 16
         js       .loop
     movhlps xmm1, xmm0
     addps   xmm0, xmm1
     movss   xmm1, xmm0
     shufps  xmm0, xmm0, 1
     addss   xmm0, xmm1
 %if ARCH_X86_64 == 0
 -    movd    r0m,  xmm0
 +    movss   r0m,  xmm0
     fld     dword r0m
