Not really. The closest thing is ARM64EC and ARM64X, a DLL built with those will let you use the same DLL for both ARM64 and x64, but only on ARM64. I know there has been work to support those in LLVM/LLD and mingw-w64, don't know about gcc/binutils support. I think they expect the installer to decide which type of DLL to install based on the host machine... -- 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
