We're working on that. LLVM 21.x should be much better in that regard. There has been no effort towards aarch64-pc-cygwin though, but also nothing that would actively prevent that. > Does Cygwin /usr/bin/clang has Aarch64 support, to compile native > Windows Aarch64 binaries if Cygwin-x86-64 runs on Windows Aarch64? I don't know about the old unmaintained version currently available, but we're working on getting LLVM/clang 20.x packaged that has all the architectures enabled, and can be used to cross-compile for aarch64-w64-mingw32 with https://github.com/mstorsjo/llvm-mingw ./build-all --host-clang -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
