--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Comment on attachment 63218 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=63218 Tentative fix I think the FE should have constant evaluated the input/output if it couldn't be made addressable, thus folding CONST_DECL into INTEGER_CST.
