| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - unsupported/Eigen/CXX11/src/Tensor/TensorReductionGpu.h Changing "pass-by-reference" argument to be "pass-by-value" instead (in a __global__ function decl). "pass-by-reference" arguments to __global__ functions are unwise, and will be explicitly flagged as errors by the newer versions of HIP. - Eigen/src/Core/util/Memory.h - unsupported/Eigen/CXX11/src/Tensor/TensorContraction.h Changes introduced in recent commits breaks the HIP compile. Adding EIGEN_DEVICE_FUNC attribute to some functions and calling ::malloc/free instead of the corresponding std:: versions to get the HIP compile working again - unsupported/Eigen/CXX11/src/Tensor/TensorReduction.h Change introduced a recent commit breaks the HIP compile (link stage errors out due to failure to inline a function). Disabling the recently introduced code (only for HIP compile), to get the eigen nightly testing going again. Will submit another PR once we have te proper fix. - Eigen/src/Core/util/ConfigureVectorization.h Enabling GPU VECTOR support when HIP compiler is in use (for both the host and device compile phases)
