lldb support. I'll be doing more testing & cleanup but I wanted to get the initial checkin done. This adds a new SBExpressionOptions::SetLanguage API for selecting a language of an expression. I added adds a new SBThread::GetInfoItemByPathString for retriving information about a thread from that thread's StructuredData. I added a new StructuredData class for representing key-value/array/dictionary information (e.g. JSON formatted data). Helper functions to read JSON and create a StructuredData object, and to print a StructuredData object in JSON format are included. A few Cocoa / Cocoa Touch data formatters were updated by Enrico to track changes in iOS 8 / Yosemite. Before we query a thread's extended information, the system runtime may provide hints to the remote debug stub that it will use to retrieve values out of runtime structures. I added a new SystemRuntime method AddThreadExtendedInfoPacketHints which allows the SystemRuntime to add key-value type data to the initial request that we send to the remote stub. The thread-format formatter string can now retrieve values out of a thread's extended info structured data. The default thread-format string picks up two of these - thread.info.activity.name and thread.info.trace_messages. I added a new "jThreadExtendedInfo" packet in debugserver; I will add documentation to the lldb-gdb-remote.txt doc soon. It accepts JSON formatted arguments (most importantly, "thread":threadnum) and it returns a variety of information regarding the thread to lldb in JSON format. This JSON return is scanned into a StructuredData object that is associated with the thread; UI layers can query the thread's StructuredData to see if key-values are present, and if so, show them to the user. These key-values are likely to be specific to different targets with some commonality among many targets. For instance, many targets will be able to advertise the pthread_t value for a thread. I added an initial rough cut of "thread info" command which will print the information about a thread from the jThreadExtendedInfo result. I need to do more work to make this format reasonably. Han Ming added calls into the pmenergy and pmsample libraries if debugserver is run on Mac OS X Yosemite to get information about the inferior's power use. I added support to debugserver for gathering the Genealogy information about threads, if it exists, and returning it in the jThreadExtendedInfo JSON result. llvm-svn: 210874
