Still slower than IAR with STM: https://www.eembc.org/viewer/?benchmark_seq=2533

Wrong: CoreMark on this page is 1082.4, which is good but not quite close to the T4. Now if you look at the latest H7's from ST it gets more interesting and better than T4's but not by much: https://www.eembc.org/viewer/?benchmark_seq=13276
