--- Comment #2 from Xi Ruoyao <xry111 at gcc dot gnu.org> --- The test file can be downloaded from http://phoronix-test-suite.com/benchmark-files/smhasher-20220822.tar.xz. Just build it with cmake and run "./SMHasher --test=Speed sha3-256". The building system enables -O3 and LTO by default. With GCC 13 I get about 180 MiB/s, but Clang 17 produces 250 MiB/s. Part of the difference is caused by the different -fsemantic-interposition default, if I pass -fno-semantic-interposition GCC 13 produces about 200 MiB/s.
