// The functions in this file are symbols that appear in Zircon's uboringssl but never used.
// In some linking approaches the build can't determine that they are unused and will fail with an
// 'unresolved symbol' error.  The simplest solution that keeps the footprint of uboringssl as small
// as possible is to simply abort if any of these unused functions are in fact used.
