GCC now includes builtins for AES acceleration instructions on RS6000 architectures, which are meant for possible future processors. These builtins, enabled with -mcpu=future, expose AES encryption, decryption, key generation, and Galois field multiplication. The new builtins provide a way to use AES acceleration when it becomes available.
