Walter Erquinigo 602497d672 [trace] [intel pt] Create a "process trace save" command ... added new command "process trace save -d <directory>". -it saves a JSON file as <directory>/trace.json, with the main properties of the trace session. -it saves binary Intel-pt trace as <directory>/thread_id.trace; each file saves each thread. -it saves modules to the directory <directory>/modules . -it only works for live process and it only support Intel-pt right now. Example: ``` b main run process trace start n process trace save -d /tmp/mytrace ``` A file named trace.json and xxx.trace should be generated in /tmp/mytrace. To load the trace that was just saved: ``` trace load /tmp/mytrace thread trace dump instructions ``` You should see the instructions of the trace got printed. To run a test: ``` cd ~/llvm-sand/build/Release/fbcode-x86_64/toolchain ninja lldb-dotest ./bin/lldb-dotest -p TestTraceSave ``` Reviewed By: wallace Differential Revision: https://reviews.llvm.org/D107669		2021-08-27 09:34:01 -07:00
