Mold 1.10 was released today by lead developer Rui Ueyama as the newest version of this high speed linker that has been outperforming GNU Gold and LLVM LLD.

Mold 1.10 now optimizes thread-local variable accesses in shared libraries when the library is linked with the "-z nodlopen" option. This optimizing for thread-local variable accesses in shared libraries is implemented for x86_64 and s390x architectures.

Over on the AArch64 side, Mold is now able to optimize GOT load by rewriting an ADDR+LDR instruction pair with an ADDR+ADD.

Mold 1.10 also adds support for the "--print-dependencies" option to print out dependency information between input files.

Mold 1.10 also has a performance regression fix for an issue in v1.9 that affected some users, among other fixes. More details on Mold 1.10 via GitHub.
