So that it can get rid of requirement of a compiler.
$ sudo ./perf test -v 109 109: Test data symbol : --- start --- test child forked, pid 844526 Recording workload... [ perf record: Woken up 2 times to write data ] [ perf record: Captured and wrote 0.354 MB /tmp/__perf_test.perf.data.GFeZO (4847 samples) ] Cleaning up files... test child finished with 0 ---- end ---- Test data symbol: Ok
