...improvement (5% or so). Note that no loop unrolling has been done; for the direct case unrolling 4 times will reduce instruction count noticeably. Using '-ftree-vectorize -ffast-math -O3' and a profile run: Original: Direct 3419k, Interpolate 9255k This version: Direct 1629k, Interpolate 8588k My loop transformations allow GCC to recognize it as vectorizable for the direct case, giving a very nice speedup. For interpolate, we're again hurt by the loop doing too much work. Note though that GCC currently does not vectorize the inner loop for interpolate as it's unable to recog...
