It takes some time to look for inline stack for callgraph addresses.
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.
