The GCC developers are proud to announce a new major GCC release, 14.1. The C frontend when targeting standards newer than C89 now considers many non-standard constructs as errors that were previously only warnings. See https://gcc.gnu.org/gcc-14/porting_to.html#warnings-as-errors for more details. C23 _BitInt Bit-precise integer types are now supported, for now only on IA-32, x86-64 and AArch64.
The C++ frontend now implements several C++26 features, some missing C++23 bits and defect report resolutions. Diagnostics involving C++ templates now quote source from the instantiation context. The libstdc++exp.a library now includes all symbols for the Filesystem TS and the experimental symbols for the C++23 std::stacktrace class, so -lstdc++exp can be used instead of -lstdc++fs. The libstdc++_libbacktrace.a library is not longer installed. Improved experimental support for C++20, C++23, and C++26. Updated parallel algorithms that are compatible with oneTBB. GCC now implements the Clang extensions __has_feature and __has_extension for the C family language frontends. The Fortran frontend now accepts -std=f2023 in preparation of support of Fortran 2023. GCC now has a new -fhardened flag to enable security hardening features available on the target platform. OpenMP and OpenACC offloading is made easier by no longer requiring explicit passing of -lm or -lgfortran to the offload device linker. The AMD GCN offload target gained support for select RDNA2 and RDNA3 graphics cards. The vectorizer can now vectorize loops which contain alternate exits such as via break statements and can now target RISC-V with a comparable feature set than other main architectures. The #pragma GCC novector pragma can be used to disable vectorization of annotated loops. GCC's Static Analyzer has been greatly improved, still mainly targeting C code. The AArch64 target supports new hardware features like SME and SME2 and can now handle GCCs function multiversioning. The IA-32/x86-64 target can now target AVX10.1 and APX supporting CPUs and can target recent and future announced CPU families. The LoongArch port got support for vector ISA extensions and the Ada and D frontends. The RISC-V port now enables SLP and loop vectorization when the vector extension is enabled and supports vector intrinsics as of the RVV 1.0 specification. Some code that compiled successfully with older GCC versions might require source changes, see http://gcc.gnu.org/gcc-14/porting_to.html for details. See https://gcc.gnu.org/gcc-14/changes.html for more information about changes in GCC 14.1. This release is available from the WWW and FTP servers listed here: https://sourceware.org/pub/gcc/releases/gcc-14.1.0/ https://gcc.gnu.org/mirrors.html The release is in the gcc-14.1.0/ subdirectory. If you encounter difficulties using GCC 14.1, please do not contact me directly. Instead, please visit http://gcc.gnu.org for information about getting help. Driving a leading free software project such as GCC would not be possible without support from its many contributors. Not only its developers, but especially its regular testers and users which contribute to its high quality. The list of individuals is too large to thank individually!
