- Summary
- [none]
- Details
-
The POWER9 backend in GNU Compiler Collection (GCC) before version 10 could optimize multiple calls of the _builtindarn 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 _builtindarn() call may be the same.
