The POWER9 backend in GNU Compiler Collection (GCC) before version 10 could optimize multiple calls of the __builtin_darn intrinsic into a single call thus reducing the entropy of the random number generator. This occurred because a volatile operation was not specified. For example within a single execution of a program the output of every __builtin_darn() call may be the same.
