// BuiltinFunc is a built-in eBPF function.
type BuiltinFunc int32

// eBPF built-in functions
//
// You can renegerate this list using the following gawk script:
//
//    /FN\(.+\),/ {
//      match($1, /\((.+)\)/, r)
//      split(r[1], p, "_")
//      printf "Fn"
//      for (i in p) {
//        printf "%s%s", toupper(substr(p[i], 1, 1)), substr(p[i], 2)
//      }
//      print ""
//    }
//
// The script expects include/uapi/linux/bpf.h as it's input.
