* Add support for Arm SVEGravatar David Tellenbach2021-01-21
| | | | | | | | | | | | This patch adds support for Arm's new vector extension SVE (Scalable Vector Extension). In contrast to other vector extensions that are supported by Eigen, SVE types are inherently *sizeless*. For the use in Eigen we fix their size at compile-time (note that this is not necessary in general, SVE is *length agnostic*). During compilation the flag `-msve-vector-bits=N` has to be set where `N` is a power of two in the range of `128`to `2048`, indicating the length of an SVE vector. Since SVE is rather young, we decided to disable it by default even if it would be available. A user has to enable it explicitly by defining `EIGEN_ARM64_USE_SVE`. This patch introduces the packet types `PacketXf` and `PacketXi` for packets of `float` and `int32_t` respectively. The size of these packets depends on the SVE vector length. E.g. if `-msve-vector-bits=512` is set, `PacketXf` will contain `512/32 = 16` elements. This MR is joint work with Miguel Tairum <miguel.tairum@arm.com>.

* Refactoring of the cost model:Gravatar Gael Guennebaud2015-10-28
| | | | | | | | | | | - Dynamic is now an invalid value - introduce a HugeCost constant to be used for runtime-cost values or arbitrarily huge cost - add sanity checks for cost values: must be >=0 and not too large This change provides several benefits: - it fixes shortcoming is some cost computation where the Dynamic case was not properly handled. - it simplifies cost computation logic, and should avoid future similar shortcomings. - it allows to distinguish between different level of dynamic/huge/infinite cost - it should enable further simplifications in the computation of costs (save compilation time)

* First part of a big refactoring of alignment control to enable the handling ↵Gravatar Gael Guennebaud2015-08-06
| | | | | | | | | of arbitrarily aligned buffers. It includes: - AlignedBit flag is deprecated. Alignment is now specified by the evaluator through the 'Alignment' enum, e.g., evaluator<Xpr>::Alignment. Its value is in Bytes. - Add several enums to specify alignment: Aligned8, Aligned16, Aligned32, Aligned64, Aligned128. AlignedMax corresponds to EIGEN_MAX_ALIGN_BYTES. Such enums are used to define the above Alignment value, and as the 'Options' template parameter of Map<> and Ref<>. - The Aligned enum is now deprecated. It is now an alias for Aligned16. - Currently, traits<Matrix<>>, traits<Array<>>, traits<Ref<>>, traits<Map<>>, and traits<Block<>> also expose the Alignment enum.
