# The call to backtrace() function fails for ARC, because for some

# reason the unwinder from libgcc returns early. Thus the usage of

# backtrace() should be disabled in perf explicitly: at build time

# backtrace() appears to be available, but it fails at runtime: the

# backtrace will contain only several functions from the top of stack,

# instead of the complete backtrace.
