oBGx2wpeth0Z0Rv3dG77D06fHbw%3D&reserved=0, isolate code
that
uses FPU in DSC to DML, where all FPU code should locate.
This change does not refactor any functions but move code around.
This is not a really bug fix, just general reworking of the FP code. I don't
know that this is stable material.
I think it's needed for a follow-on patch in this series, right?
I'm not sure. This series comes from Sasha. I'm not sure what his dependency chain looks like.
