This function uses backtrace and backtrace_symbols functions defined as GNU extensions. In Android, bionic does not offer support for these functions and compilation will fail with the following error: target C: libperf <= tools/perf/util/util.c tools/perf/util/util.c:4:22: fatal error: execinfo.h: No such file or directory compilation terminated. Add a compile-time option (NO_BACKTRACE) to enable or disable self-debugging functionality in perf. This can also help in debugging since it offers the possibility to turn on/off printing the backtrace.
