bcc is a front-end tool for eBPF : https://github.com/iovisor/bcc/blob/master/README.md. eBPF is the most powerful Linux tracer, and bcc allows to write eBPF scripts in C and PYTHON3. BCC requires enabling LLVM backend BPF support.

Build LLVM with run-time type information. LLVM can be built

without rtti, but turning it off changes the ABI of C++
|

programs.

This features is needed to build the Gallium Nouveau driver
|

or the Clover OpenCL state tracker when llvm support is

enabled.
