This can be done during decl merging, by adding the DECL_TARGET_SPECIFIC tree of the declaration decl to the definition decl. However, with function multiversioning, this will become a problem as multiversioning does not treat two decls with different target attributes as identical. Since we are enabling multiversioning by default, atleast in C++ front-end for now, IMO, it is better to insist that the definition and declaration contain identical target attributes. > > > Thanks.
