--- Comment #4 from Benjamin Schindler <beschindler at gmail dot com> --- (In reply to Marc Glisse from comment #2) > (note that a minimal, self-contained testcase would be much better and > shouldn't be hard to produce) I don't mind doing so, but I don't quite know what is required to trigger this isssue. After chatting with a friend, I realized yet another issue with the generated assembly: it makes a lot of use of unaligned reads (movdqu) as opposed to movdqa. Eigen types are by design aligned and thus, it should be possible to use the (from what I've been told) faster aligned reads Cheers
