WebAug 4, 2024 · Define EIGEN_DONT_ALIGN_STATICALLY. That disables all 16-byte (and above) static alignment code, while keeping 16-byte (or above) heap alignment. This has the effect of vectorizing fixed-size objects (like Matrix4d) through unaligned stores ... WebThe EIGEN_DONT_ALIGN option still exists in Eigen 3, but it has a new cousin: EIGEN_DONT_ALIGN_STATICALLY. It allows to get rid of all static alignment issues while keeping alignment of dynamic-size heap-allocated arrays, thus keeping vectorization for dynamic-size objects. Aligned Map objects bt種子搜尋引擎

Webthat the integration of the following C++11 features makes sense: - initializer lists. - move construction and assignment (e.g. sparse is still missing) - noexcept (maybe useful in the future) The reason of this limitation is primarily that most of the other features. require redundant code. Webfixed-size matrix product crashes when EIGEN_DONT_ALIGN_STATICALLY is defined … WebIf you want to know why defining EIGEN_DONT_VECTORIZE does not by itself disable 16-byte alignment and the assertion, here's the explanation: It doesn't disable the assertion, because otherwise code that runs fine without vectorization would suddenly crash when enabling vectorization. bt种子下载工具
