--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
FYI, this used to work fine before r256634 with which it started to ICE:
pr85804.c: In function ‘main’:
pr85804.c:4:5: internal compiler error: in vect_permute_load_chain, at
tree-vect-data-refs.c:5511
 int main() {
     ^~~~
Starting with r257492 we don't ICE anymore, but miscompile it.
