So it provides new options "--inline-line" and "--inline-name" to let user decide if enable this feature. --inline-name: If a callgraph address belongs to an inlined function, the inline stack will be printed. Each entry is the inline function name. --inline-line: If a callgraph address belongs to an inlined function, the inline stack will be printed. Each entry is the inline function source line.
