This is the first feature update to LLVM for 2026 and just in time for incorporating into various spring software releases. Some of the LLVM/Clang 22 feature highlights include:
- Clang now supports Named Loops for C2y, among other early C2y language work.
- More SSE, AVX, and AVX-512 intrinsics can now be used in C++ constant expressions. Some intrinsics have also been converted to wrap __builtin intrinsics.
- Clang support for Ampere Computing's Ampere1C CPUs . Ampere-1C processor cores are likely for Ampere Aurora.
- Dropping the AVX10 256-bit vs. 512-bit options now that Intel thankfully abandoned their AVX10 256-bit only plans.
- There is support for Intel Wildcat Lake with -march=wildcatlake and Intel Nova Lake with -march=novalake with APX and AVX10.2 .
- Some long overdue optimizations for AMD Zen 4 .
- Clang on ARM64 now supports the Arm C1 Nano, C1 Pro, C1 Prmeium, and C1 Ultra processors.
- LLVM assembler and disassembler support for Armv9.7-A (2025) architecture extensions.
- RISC-V support for Zvfbfa for additional BF16 vector compute support.
- NVIDIA Olympus CPU scheduling model is added.
- Intel upstreamed the libsycl SYCL Runtime Library .
- LLVM 22 began seeing Distributed ThinLTO "DTLTO" support upstreaming .
- AMD contributed BFloat16 for LLVM's SPIR-V target .
- The Ssctr and Smctr RISC-V extensions are also deemed no longer experimental nor are Qualcomm's Xqci and Xqccmp vendor extensions.
- LLVM 22 has finally eliminated the last support for Google Native Client (NaCl).
LLVM 22.1 with sub-projects like Clang 22.1 can all be downloaded from LLVM on GitHub . LLVM 22.1.1 will be out in two weeks with now kicking off the bi-weekly point releases for addressing any early bugs and fallout from this big compiler update.
