--- Comment #19 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
It turns out that there is yeat another #ifdef __clang__ I missed in the gfx
library, so the vectorised code produced by clang is hand written in the
extensions discussed in PR88602.

Sorry for confusion. However I think the simplified testcase is still perfe=
ctly
vectorisable and we should add the div patterns as discussed.=
