The analysis is at the bytecode 2N/A // conservative results. // retrieval of interprocedural escape information // The given argument does not escape the callee. // The given argument escapes the callee, but does not become globally // The given argument does not escape globally, and may be returned. // True iff only input arguments are returned. // True iff only newly allocated unescaped objects are returned. // Tracking of argument modification // Copy dependencies from this analysis into "deps" // dump escape information
