As a result, all FPU flags are only used in the DML code. I guess we might have issues in other non-x86 platforms, but this is something that we can improve over time, and from Ao message, it looks like that DCN is working on ARM. > > At this point, my main concern is that enabling ARM64 may causes some compilation issues that we did not reproduce yet.
