at each public stop to improve performance a bit. Most of the information lldb needed was already in the jThreadsInfo response; complete that information and catch a few cases where we could still fall back to getting the information via discrete memory reads. debugserver adds 'associated_with_dispatch_queue' and 'dispatch_queue_t keys to the jThreadsInfo response for all the threads. lldb needs the dispatch_queue_t value. And associated_with_dispatch_queue helps to identify which threads definitively don't have any queue information so lldb doesn't try to do memory reads to get that information just because it was absent in the jThreadsInfo response. Remove the queue information from the questionmark (T) packet. We'll get the information for all threads via the jThreadsInfo response - sending the information for the stopping thread (on all the private stops, plus the less frequent public stop) was unnecessary information being sent over the wire. SystemRuntimeMacOSX will try to get information about queues by asking the Threads for them, instead of reading memory. ProcessGDBRemote changes to recognize the new keys being sent in the jThreadsInfo response. Changes to ThreadGDBRemote to track the new information. Also, when a thread is marked as definitively not associated with a libdispatch queue, don't fall back to the system runtime to try memory reads to find the queue name / kind / ID etc. <rdar://problem/23309359> llvm-svn: 257453 |
