No diffs, as expected. Except there is a minor 2-byte change on Windows x86 for a generic Dataflow constructor scenario. Looks to be because we don't contain a constant anymore due to a new: There is a +0.01% TP hit due to the call to determine register size rather than directly hardcoding a constant. I imagine we could fix this by caching the largest vector size instead of doing a dynamic query each time... |
