high-level tracing language for Linux eBPF

 BPFtrace is a high-level tracing language for Linux enhanced Berkeley
 Packet Filter (eBPF) available in recent Linux kernels (4.x). BPFtrace
 uses LLVM as a backend to compile scripts to BPF-bytecode and makes
 use of BCC for interacting with the Linux BPF system, as well as
 existing Linux tracing capabilities: kernel dynamic tracing (kprobes),
 user-level dynamic tracing (uprobes), and tracepoints. The BPFtrace
 language is inspired by awk and C, and predecessor tracers such as
 DTrace and SystemTap.
