Actually, neither does dwarf2out.c specifically check for it, it assumes it's defined if DWARF2_UNWIND_INFO does. #ifdef DWARF2_UNWIND_INFO /* On entry, the Canonical Frame Address is at SP. */ dwarf2out_def_cfa (NULL, STACK_POINTER_REGNUM, INCOMING_FRAME_SP_OFFSET); initial_return_save (INCOMING_RETURN_ADDR_RTX); #endif Can you try the obvious patch here (surrounding INCOMING_RETURN_ADDR_RTX with an ifdef)?
