--- Comment #4 from Tamar Christina <tnfchris at gcc dot gnu.org> ---
Looks like re-vectorization currently fails with

antilog.c:34:27: note:   vectype: vector(4) float
antilog.c:34:27: note:   Build SLP for _10 = BIT_FIELD_REF <_2, 32, 0>;
antilog.c:34:27: missed:   Build SLP failed: BIT_FIELD_REF not supported

I'll investigate.
