public class ProfilingInfoTest extends GraalCompilerTest
NOTE: These tests are actually not very robust. The problem is that only partial profiling
information may be gathered for any given method. For example, HotSpot's advanced compilation
policy can decide to only gather partial profiles in a first level compilation (see
AdvancedThresholdPolicy::common(...) in advancedThresholdPolicy.cpp). Because of this,
occasionally tests for ProfilingInfo.getNullSeen(int) can fail since HotSpot only set's
the null_seen bit when doing full profiling.
