mold 3.0 rewrites the high-speed linker in Rust with performance on par

github.com 6 min read Editor score 7/10

The first Rust release of mold is intended as a drop-in replacement, with the same options and target architectures and linking performance on par with the C++ version. The rewrite and its compatibility goals matter to teams tuning build pipelines and evaluating linkers.

What

Mold 3.0 is the first Rust release of the high-speed linker, rewritten from C++.

How

It keeps the command-line options, target architectures, output, and linking performance of 2.42.1; compatibility testing found no regressions.

Why it matters

Bounds-checked reads make corrupted-input handling safer: faulty accesses stop with a panic instead of an out-of-bounds read and segmentation fault.
