void Heap::deleteAllCompiledCode()
{
    // If JavaScript is running, it's not safe to delete code, since we'll end
    // up deleting code that is live on the stack.
    if (m_globalData->dynamicGlobalObject)
        return;

    for (ExecutableBase* current = m_compiledCode.head(); current; current = current->next()) {
        if (!current->isFunctionExecutable())
            continue;
        static_cast<FunctionExecutable*>(current)->clearCodeIfNotCompiling();
    }

    m_dfgCodeBlocks.clearMarks();
    m_dfgCodeBlocks.deleteUnmarkedJettisonedCodeBlocks();
}


I think it is not calling GarbageCollector. Sorry incase i'm wrong. Can you please show me where it is calling the GC?

 +    WebCore::StorageThread::releaseFastMallocFreeMemoryInAllThreads();
 +#if ENABLE(WORKERS)
 +    WebCore::WorkerThread::releaseFastMallocFreeMemoryInAllThreads();
 +#endif
 +    WTF::releaseFastMallocFreeMemory();

Anyhow releasing Workers and FastMalloc stuffs needed know?
