--- Comment #6 from Gaius Mulley <gaius at gcc dot gnu.org> --- Created attachment 54920 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54920&action=edit Proposed fix for TestLong4.mod (ZTYPE fix) Here is a proposed patch to allow testLong4.mod to compile without warning. The ZTYPE is changed to int128 (or int64) if int128 is unavailable and constant literals are built from widest_int. The widest_int is converted into the tree type and checked for overflow. m2expr_interpret_integer and append_m2_digit are removed.
