> The C++ FE marks the virtual function as TREE_PUBLIC but neither sets > TREE_STATIC nor DECL_EXTERNAL. Thus probably lto_symtab_resolve_can_prevail_p I think it is bug doing so, we probably should fix this at C++ thunk side. I am not expert here, but the old non-RTL path was actually going through the C++ import/export code that we might want to do too. Thanks for looking into this! -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42320
