With the GCC 16.1 compiler released last Thursday, I have begun running more compiler benchmarks on this first GCC 16 stable feature release. GCC 16 comes heavy on new changes in being the annual feature release and delivering changes from AMD Zen 6 and Arm AGI CPU support to new C++ features and even the Algol 68 programming language front-end. It's also looking quite good in the performance department relative to the GCC 15 compiler from last year.
