* Remove HasCast and fix packetmath cast tests.Gravatar Antonio Sanchez2020-06-11
| | | | | | | | | | | The use of the `packet_traits<>::HasCast` field is currently inconsistent with `type_casting_traits<>`, and is unused apart from within `test/packetmath.cpp`. In addition, those packetmath cast tests do not currently reflect how casts are performed in practice: they ignore the `SrcCoeffRatio` and `TgtCoeffRatio` fields, assuming a 1:1 ratio. Here we remove the unsed `HasCast`, and modify the packet cast tests to better reflect their usage.

* Fix incorrect usage of `if defined(EIGEN_ARCH_PPC)` => `if EIGEN_ARCH_PPC`Gravatar Yong Tang2020-05-28
| | | | | | | | | | | | | | This PR tries to fix an incorrect usage of `if defined(EIGEN_ARCH_PPC)` in `Eigen/Core` header. In `Eigen/src/Core/util/Macros.h`, EIGEN_ARCH_PPC was explicitly defined as either 0 or 1. As a result `if defined(EIGEN_ARCH_PPC)` will always be true. This causes issues when building on non PPC platform and `MatrixProduct.h` is not available. This fix changes `if defined(EIGEN_ARCH_PPC)` => `if EIGEN_ARCH_PPC`.

* Add missing packet ops for bool, and make it pass the same packet op unit ↵Gravatar Rasmus Munk Larsen2020-05-14

Remove packet op pnot, which is not needed for anything other than pcmp_le_or_nan, which can be done in other ways. 2. Remove the "HasInsert" enum, which is no longer needed since we removed the corresponding packet ops. 3. Add faster pselect op for Packet4i when SSE4.1 is supported. Among other things, this makes the fast transposeInPlace() method available for Matrix<bool>.

* Possibility to specify user-defined default cache sizes for GEBP kernelGravatar David Tellenbach2020-05-08
| | | | | | | | | | | | | | Some architectures have no convinient way to determine cache sizes at runtime. Eigen's GEBP kernel falls back to default cache values in this case which might not be correct in all situations. This patch introduces three preprocessor directives `EIGEN_DEFAULT_L1_CACHE_SIZE` `EIGEN_DEFAULT_L2_CACHE_SIZE` `EIGEN_DEFAULT_L3_CACHE_SIZE` to give users the possibility to set these default values explicitly.
