Walter Erquinigo fb19f11ef4 [trace][intel-pt] Scaffold the 'thread trace start | stop' commands ... Depends on D90490. The stop command is simple and invokes the new method Trace::StopTracingThread(thread). On the other hand, the start command works by delegating its implementation to a CommandObject provided by the Trace plugin. This is necessary because each trace plugin needs different options for this command. There's even the chance that a Trace plugin can't support live tracing, but instead supports offline decoding and analysis, which means that "thread trace dump instructions" works but "thread trace start" doest. Because of this and a few other reasons, it's better to have each plugin provide this implementation. Besides, I'm using the GetSupportedTraceType method introduced in D90490 to quickly infer what's the trace plug-in that works for the current process. As an implementation note, I moved CommandObjectIterateOverThreads to its header so that I can use it from the IntelPT plugin. Besides, the actual start and stop logic for intel-pt is not part of this diff. Reviewed By: clayborg Differential Revision: https://reviews.llvm.org/D90729		2020-11-18 18:24:36 -08:00
