--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Those routines need to be enabled for ppc in libgcc, like they are already enabled for s390x. ligcc has DPD _BitInt support since r16-920-ga57ea0a189b95228d524841497684b029cc51c00 So, all you need to make sure is that those are built and included in libgcc.a (note, DFP suipport is never included in libgcc_s.so.1).
