Hi,

I'm currently working on a mixed-architecture Windows application that uses arm64ec for compatibility with x64 native libraries on ARM-based devices like the Surface Pro X.

I've been trying to build Protobuf for the arm64ec target, but it seems that there is no official support or documentation for this architecture. While Protobuf builds and runs fine on native arm64 or x64, the arm64ec ABI is a key requirement for many modern Windows-on-ARM development scenarios, especially where interoperability with x64-only libraries is required.

Are there any plans to support arm64ec builds officially in the future?

If not currently planned, would it be possible to consider it as a feature request? It would be greatly appreciated by developers targeting hybrid environments.

Thanks in advance!
