(TARGET_CXX): Use it. * target.h (struct gcc_target): Add cdtor_returns_this. * config/arm/arm.c (arm_cxx_cdtor_returns_this): New function. (TARGET_CXX_CDTOR_RETURNS_THIS): Define. * doc/tm.texi: Document TARGET_CXX_CDTOR_RETURNS_THIS. gcc/cp/ * Make-lang.in (cp/semantics.o, cp/optimize.o): Depend on TARGET_H. * cp-tree.h (struct language_function): Rename x_dtor_label to x_cdtor_label. (dtor_label): Rename ... (cdtor_label): ... to this. * decl.c (begin_constructor_body): Remove. (check_special_function_return_type): Maybe change the return type. (grokdeclarator): Pass the class type. (start_preparsed_function): Constructors may need a return label. (finish_constructor_body, finish_destructor_body): Set the return value. (begin_function_body): Don't call begin_constructor_body. (finish_function): Don't warn for constructors or destructors. (implicitly_declare_fn): Maybe change the return type. * optimize.c: Include target.h. (maybe_clone_body): Remap the function result. * semantics.c: Include target.h. (finish_return_stmt): Maybe jump to return label for constructors.
