GCC 16 Released — C++20 Now Default, AMD Zen 6 Support, Algol 68 Frontend Added
GNU Project / Hacker News·medium signal
The GNU Compiler Collection 16.1 shipped with C++20 as the default standard (up from C++17), initial AMD Zen 6 'znver6' support, Intel AVX10.2 and APX for Nova Lake, and a new Algol 68 language frontend. New SARIF diagnostic output replaces JSON, and link-time optimization gains speculative devirtualization for indirect calls. The C++20 default change alone affects every C++ project that doesn't pin a standard version. 135 points, 18 comments on HN.
