// Workaround for crosbug:629593.  Using AFDO on the tcmalloc files is
// causing problems. The tcmalloc files depend on stack layouts and
// AFDO can mess with them. Better not to use AFDO there.  This is a
// temporary hack. We will add a mechanism in the build system to
// avoid using -fauto-profile for tcmalloc files.
#if !defined(__clang__) && (defined(OS_CHROMEOS) || __GNUC__ > 5)
// Note that this option only seems to be available in the chromeos GCC 4.9
// toolchain, and stock GCC 5 and up.
