The details are: large packets (like large memory reads (m packets) or large binary memory reads (x packet)) can get responses that come in across multiple read() calls. The while loop that was added meant that if only a partial packet came in (like only "$abc" coming for a response) GDBRemoteCommunication::CheckForPacket() was called, it would deadlock in the while loop because no more data is going to come in as this function needs to be called again with more data from another read. So the original fix will need to be corrected and resubmitted. <rdar://problem/18853744> llvm-svn: 221181
