--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
The nodes are external for whatever reason, you need -ffast-math as well btw.
The externals are because
t.c:6:7: note: ==> examining statement: _9 = MEM[(double *)a_14(D) + 16B];
t.c:6:7: missed: BB vectorization with gaps at the end of a load is not
supported
t.c:6:14: missed: not vectorized: relevant stmt not supported: _9 =
MEM[(double *)a_14(D) + 16B];
t.c:6:7: note: Building vector operands of 0x5235b90 from scalars instead
we ended up vectorizing b[1]/b[2].
