@davemgreen You’re absolutely right about tryCandidate in the scheduler pass. I tried to find a pattern to ignore such cases, but no luck with that. I’ve also done more benchmarking (e.g. different Eigen’s and TSVC's kernels) and generally there are more beneficial cases than regression. Should we merge the changes in this case?
