--- Comment #11 from Richard Biener <rguenth at gcc dot gnu.org> ---
The issue gather scatter detection - we do not anticipate the non-mask use in
the address calculation for the gather:
(gdb) p gs_info
$12 = {ifn = IFN_LAST, decl = <tree 0x0>, base = <nop_expr 0x7ffff6cfed80>,
offset = <ssa_name 0x7ffff6e0d870 2>, scale = 8,
offset_dt = vect_internal_def,
offset_vectype = <vector_type 0x7ffff6ceaa80>,
element_type = <real_type 0x7ffff6e2a498 double>,
memory_type = <real_type 0x7ffff6e2a498 double>}
(gdb) p debug_generic_expr (0x7ffff6ceaa80)
vector(8) <signed-boolean:1>
it's a bit difficult to avoid this during vect_check_gather_scatter where
we look through the conversion from _Bool to unsigned int given this happens
before pattern recog. But we can catch it easily after the fact.
