Speaking of OpenBSD: Yes, you read that right. Modern development tools in the form of the LLVM compiler infrastructure is well on its way to supporting OpenBSD/sparc64 along with other more conventional architectures. The support is now ready for testing, via a patch set presented by Kirill A. Korinsky in a message to the tech@ mailing list, with the subject LLVM toolchain for sparc64 . ↫ Peter N. M. Hansteen On a related note, the the entire LLVM stack (version 19.1.7, including llvm’s binutils, clang, ldd) has also been ported to the SPARC version of Solaris 11 Express (snv_151a). This should make it possible to also port things like Rust and Zig to this same version of Solaris on SPARC, which is good news, because this release supports SPARC hardware long dropped by the current Solaris builds from Oracle.
