Also, the changes in this PR have been in made in such way that they only affect architectures on which the intrinsic is implemented. Would you also be able to test the changes in this PR to make sure no regressions are introduced on these archs?

Thanks! I'll test it. We will need separate issues for these platforms because they are maintained by different people.
