26# reason the unwinder from libgcc returns early. Thus the usage of
27# backtrace() should be disabled in perf explicitly: at build time
28# backtrace() appears to be available, but it fails at runtime: the
29# backtrace will contain only several functions from the top of stack,
30# instead of the complete backtrace.
