private static void printMemoryUsage(final String phaseName, final FunctionNode functionNode) {
    LOG.info(phaseName + " finished. Doing IR size calculation...");

    final ObjectSizeCalculator osc = new ObjectSizeCalculator(ObjectSizeCalculator.getEffectiveMemoryLayoutSpecification());
    osc.calculateObjectSize(functionNode);

    final List<ClassHistogramElement> list = osc.getClassHistogram();

    final StringBuilder sb = new StringBuilder();
    final long totalSize = osc.calculateObjectSize(functionNode);
    sb.append(phaseName).append(" Total size = ").append(totalSize / 1024 / 1024).append("MB");
    LOG.info(sb);

    Collections.sort(list, new Comparator<ClassHistogramElement>() {
        @Override
        public int compare(ClassHistogramElement o1, ClassHistogramElement o2) {
            final long diff = o1.getBytes() - o2.getBytes();
