* Specialize pldexp_double and pfdexp_double and get rid of Packet2l ↵Gravatar Rasmus Munk Larsen2020-09-30
| | | | definition for SSE. SSE does not support conversion between 64 bit integers and double and the existing implementation of casting between Packet2d and Packer2l results in undefined behavior when casting NaN to int. Since pldexp and pfdexp only manipulate exponent fields that fit in 32 bit, this change provides specializations that use existing instructions _mm_cvtpd_pi32 and _mm_cvtsi32_pd instead.
* Fix alignedbox 32-bit precision test failure.Gravatar Antonio Sanchez2020-09-30
| | | | | | | | | | | | | | | The current `test/geo_alignedbox` tests fail on 32-bit arm due to small floating-point errors. In particular, the following is not guaranteed to hold: ``` IsometryTransform identity = IsometryTransform::Identity(); BoxType transformedC; transformedC.extend(c.transformed(identity)); VERIFY(transformedC.contains(c)); ``` since `c.transformed(identity)` is ever-so-slightly different from `c`. Instead, we replace this test with one that checks an identity transform is within floating-point precision of `c`. Also updated the condition on `AlignedBox::transform(...)` to only accept `Affine`, `AffineCompact`, and `Isometry` modes explicitly. Otherwise, invalid combinations of modes would also incorrectly pass the assertion.

* Fix for ROCm/HIP breakage - 200921Gravatar Deven Desai2020-09-22
| | | | | | | | | | | | | The following commit causes regressions in the ROCm/HIP support for Eigen https://gitlab.com/libeigen/eigen/-/commit/e55182ac09885d7558adf75e9e230b051a721c18 I suspect the same breakages occur on the CUDA side too. The above commit puts the EIGEN_CONSTEXPR attribute on `half_base` constructor. `half_base` is derived from `__half_raw`. When compiling with GPU support, the definition of `__half_raw` gets picked up from the GPU Compiler specific header files (`hip_fp16.h`, `cuda_fp16.h`). Properly supporting the above commit would require adding the `constexpr` attribute to the `__half_raw` constructor (and other `*half*` routines) in those header files. While that is something we can explore in the future, for now we need to undo the above commit when compiling with GPU support, which is what this commit does. This commit also reverts a small change in the `raw_uint16_to_half` routine made by the above commit. Similar to the case above, that change was leading to compile errors due to the fact that `__half_raw` has a different definition when compiling with DPU support.
