--- Comment #12 from Jason Merrill <jason at gcc dot gnu.org> --- Author: jason Date: Thu Mar 7 15:10:22 2019 New Revision: 269459 URL: https://gcc.gnu.org/viewcvs?rev=269459&root=gcc&view=rev Log: PR c++/80916 - spurious "static but not defined" warning. Nothing can refer to an internal decl with no definition, so we shouldn't treat such a decl as a possible devirtualization target. * gimple-fold.c (can_refer_decl_in_current_unit_p): Return false for an internal symbol with DECL_EXTERNAL. Added: trunk/gcc/testsuite/g++.dg/warn/unused-fn1.C Modified: trunk/gcc/ChangeLog trunk/gcc/gimple-fold.c
