Mold 2.32 is out as the newest feature release for this high speed code linker that rivals LLVM LLD and GNU Gold.

With Mold 2.32 comes support for faster Identical Code Folding (ICF) as a means of finding identical functions and merging them to reduce the size of the output file.Identical Code Folding with Mold has been found to be very helpful for template-heavy C++ programs. With Mold 2.32, their ICF algorithm is around 50% faster than with previous versions.

Mold 2.32 also adds support for the "-z rodynamic" option to increase its compatibility with LLVM LLD. The option will place the ".dynamic" sections into read-only segments.


The Mold 2.32 linker also has a variety of bug fixes, including for issues on ARM64, POWER 64-bit, and LoongArch.
