--- 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.
