Inline flowgraphs only for call-sites for which there was a minimal number of calls during an instrumented run of the program. Callee flowgraphs are considered candidates based on a weight heuristic like for basic inlining. (see :config:`translation.backendopt.inline`, :config:`translation.backendopt.profile_based_inline_threshold` ). The option takes as value a string which is the arguments to pass to the program for the instrumented run. This optimization is not used by default.
