LLVM 21.1.1 Ships A Variety Of Compiler Fixes

Written by Michael Larabel in LLVM on 10 September 2025 at 05:42 AM EDT. 3 Comments
For those preferring for the first point release to major new compiler releases before upgrading, LLVM 21.1.1 is out today along with the likes of Clang 21.1.1 for this widely-used open-source compiler stack.

LLVM 21.1 released in late August with many significant improvements and other enhancements as the newest half-year feature release to LLVM. In going off their typical bi-weekly point release regiment, LLVM 21.1.1 is now available.

LLVM 21.1.1 fixes a variety of issues that have turned up since release. KKVN 21.1.1 takes care of various Clang bugs, architecture-specific issues such as for Xtensa and RISC-V, correcting the download links for Windows on Arm packages, using IRPGO rather than FE PGO for CMake caches, adding pointer auth documentation, fixing the MLIR target export in CMake, and various other random fixes throughout.

Downloads and more details on the LLVM 21.1.1 release via LLVM.org.
