While investigating JFR profiles with Graal we noticed that Graal had many fewer samples as compared to C2. It appears more recent versions of JFR checks CodeBlob::is_frame_complete_at and skips any frames where this return false. JVMCI doesn't provide any way to set this value so it always returns false for JVMCI compiled methods and stubs.
