Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- tree index = fold_build2 (TRUNC_DIV_EXPR, integer_type_node, offset_cst, byte_size); looks wrong. offset_cst probably doesn't have integer_type_node type, byte_size almost surely. If you want to perform a signed division, you should use ssizetype and fold_convert the arguments to ssizetype.
