GCC 14.1 has been released today as the first stable compiler release in the [1]GCC 14 series. GCC 14.1 brings one year worth of improvements to this open-source compiler from new CPU support and new ISA extensions to new C/C++ language features, static analyzer improvements, new AMD GPU support, and many other additions.
GCC 14.1 is a big compiler update with a lot in store. From my daily monitoring of GCC 14 development, some of the key highlights to look forward to in this version include:
- More C23 features are implemented like bit-precise integer types. [2]The -std=c23 and -std=gnu23 compiler flags are now supported too.
- Support for more C++26 features like unevaluated strings, user-generated static_assert messages, and other features.
- GCC's Fortran front-end now supports -std=f2023 as it works on Fortran 2023 support.
- Limited support for the Intel Advanced Performance Extensions (APX).
- [3]Intel AVX10.1 support is also added to GCC 14.
- New Intel CPU support includes for Clearwater Forest, Arrow Lake, Lunar Lake, and Panther Lake.
- [4]AMD Zen 5 support is added with the new -march=znver5 option .
- Intel Xeon Phi CPU support has been deprecated and will be removed in GCC 15.
- GCC on AArc64 now supports the Microsoft Cobalt 100, Ampere-1B, Arm Cortex A520, Arm Cortex A720, and Arm Cortex X4 processors.
- The AMDGPU Radeon back-end now supports GCN5, RDNA2, and RDNA3 graphics processors.
- The Itanium IA64 target ports have been declared obsolete after being unmaintained for years. GCC 15 will be dropping the Itanium support.
- The NIOS2 targets have also been declared obsolete and to be removed in GCC 15.
- [5]The new "-fhardened" helper flag that enables a set of hardening flags.
- GCC's vectorizer can now vectorize loops that contain any number of early breaks.
- OpenMP and OpenACC improvements.
- GCC's Ada compiler front-end now supports the LoongArch architecture.
- New LoongArch ISA extensions like LSX and LASX SIMD extensions.
- Support for many new RISC-V ISA extensions such as for the vector crypto work, code size reduction, and various vendor extensions.
- Continued enhancements to the static analyzer support in GCC 14 for the C language.
- [6]Better visualizing of buffer overflows with the static analyzer.
