Do you mean if the caller is an x86_64 function running in the emulator on Windows Arm64? I think this will still work, as the emulator will work out the entry thunks, so we should still be able to call it in this way. It would regardless only be a problem if the x86_64 code was calling in to libomp directly, and I can't really think why you wouldn't just use the x86_64 libomp in that case?

If you meant using the library on x86_64 Windows, using arm64ec libraries there isn't supported at all anyways.
