mold 1.6.0 is a new release of the high-speed linker. This release adds support for two IBM-based platforms, though we are not affiliated with IBM. We are happy to take donations and/or make support contracts. If you are interested in financially supporting the project, please visit our GitHub Sponsors page.

New features

  • [ppc64] mold now supports the original 64-bit big-endian PowerPC ABI (which is also known as PPC64 ELFv1 or just ppc64), so that you can build applications for older PPC64 systems with mold. Note that this should not be confused with the modern PPC64 ELFv2 ABI (which is also known as ppc64le), which is already supported by mold.
  • [s390x] Linux/s390x is now supported. Linux/s390x is the Linux environment on IBM z/Architecture mainframes. I've personally never seen a mainframe, but we wanted to support it because many Linux distros actively support that target, which in turn means there are many enterprise users who are using IBM mainframes. Speaking of the porting effort, we do not only port our linker to s390x but also found a couple of issues with the existing GCC toolchain for s390x. So, we are improving the whole IBM mainframe ecosystem!
  • mold now creates smaller output files. It is most noticeable on targets with large page sizes such as PPC64 (on which the common page size is 64 KiB), but even on x86-64, it should save a few kilobytes per an output file.

Bug fixes and compatibility improvements

  • [arm64] mold can now link executables with -static-pie. Previously, executables linked with that flag crashed immediately. (fc66759)
