--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 43150 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43150&action=edit gcc8-pr83882.patch Possible untested fix. Can't test it even with a cross-compiler on the testcase, because hppa seems be completely broken since the GET_MODE_*SIZE changes: ../../gcc/config/pa/pa.h:601:43: error: invalid cast from type 'poly_uint16 {aka poly_int<1, short unsigned int>}' to type 'long int'
