Zig's Native x86 Backend Achieves 70% Faster Compilation

2025-06-09

The Zig compiler team announced that its native x86 backend is now production-ready, delivering significant speed improvements. Compared to the LLVM backend, the Zig backend boasts a 70% compilation speedup, reducing build times from 75 seconds to 20 seconds on large projects. This is attributed to optimizations in code generation and parallelization. Future plans include aarch64 support. This release also includes improved UBSan error messages for better debugging and enhanced cross-compilation support for FreeBSD and NetBSD.
