--- Comment #6 from Iain Sandoe <iains at gcc dot gnu.org> 2010-09-29 17:26:51 UTC --- (In reply to comment #5) > rs6000_builtin_decl should be working correctly. Indeed, I suspect it is because we patch the builtin names to append $LDBL128 for the case that we have 128bit long doubles. However, I've not had a chance to investigate why that patching process does not result in a correctly emitted builtin (or maybe the target needs to get to opportunity to do so in lto).
