* Fix NEON sqrt for 32-bit, add prsqrt.Gravatar Antonio Sanchez2021-02-26
| | | | | | | | | | | | With !406, we accidentally broke arm 32-bit NEON builds, since `vsqrt_f32` is only available for 64-bit. Here we add back the `rsqrt` implementation for 32-bit, relying on a `prsqrt` implementation with better handling of edge cases. Note that several of the 32-bit NEON packet tests are currently failing - either due to denormal handling (NEON versions flush to zero, but scalar paths don't) or due to accuracy (e.g. sin/cos).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original will saturate if the input does not fit into an integer type. Here we fix this, returning the input if it doesn't have enough precision to have a fractional part. Also added `pceil` for NEON. Fixes #1969.

* Some improvements for kissfft from Martin Reinecke(pocketfft author):Gravatar Guoqiang QI2021-02-24
| | | | | | 1.Only computing about half of the factors and use complex conjugate symmetry for the rest instead of all to save time. 2.All twiddles are calculated in double because that gives the maximum achievable precision when doing float transforms. 3.Reducing all angles to the range 0<angle<pi/4 which gives even more precision.
* Add `invoke_result` and eliminate `result_of` warnings for C++17+.Gravatar Antonio Sanchez2021-02-24
| | | | | | | | | | | | | | | | | The `std::result_of` meta struct is deprecated in C++17 and removed in C++20. It was still slipping through due to a faulty definition of `EIGEN_HAS_STD_RESULT_OF`. Added a new macro `EIGEN_HAS_STD_INVOKE_RESULT` and `Eigen::internal::invoke_result` implementation with fallback for pre C++17. Replaces the `result_of` definition with one based on `std::invoke_result` for C++17 and higher. For completeness, added nullary op support for c++03. Fixes #1850.

* Fix CUDA device new and delete, and add test.Gravatar Antonio Sanchez2021-02-24

* Eliminate CMake FindPackageHandleStandardArgs warnings.Gravatar Antonio Sanchez2021-02-24
| | | | | | | | | | | | | | | | | CMake complains that the package name does not match when the case differs, e.g.: ``` CMake Warning (dev) at /usr/share/cmake-3.18/Modules/FindPackageHandleStandardArgs.cmake:273 (message): The package name passed to `find_package_handle_standard_args` (UMFPACK) does not match the name of the calling package (Umfpack). This can lead to problems in calling code that expects `find_package` result variables (e.g., `_FOUND`) to follow a certain pattern. Call Stack (most recent call first): cmake/FindUmfpack.cmake:50 (find_package_handle_standard_args) bench/spbench/CMakeLists.txt:24 (find_package) This warning is for project developers. Use -Wno-dev to suppress it. ``` Here we rename the libraries to match their true cases.
* Disable fast psqrt for NEON.Gravatar Antonio Sanchez2021-02-23
| | | | | | | Accuracy is too poor - requires at least two Newton iterations, but then it is no longer significantly faster than `vsqrt`. Fixes #2094.
* Fix check if GPU compile phase for std::hashGravatar Antonio Sanchez2021-02-23
|
* Fix some CUDA warnings.Gravatar Antonio Sanchez2021-02-24
| | | | | | | | | | | | | | | | | Added `EIGEN_HAS_STD_HASH` macro, checking for C++11 support and not running on GPU. `std::hash<float>` is not a device function, so cannot be used by `std::hash<bfloat16>`. Removed `EIGEN_DEVICE_FUNC` and only define if `EIGEN_HAS_STD_HASH`. Same for `half`. Added `EIGEN_CUDA_HAS_FP16_ARITHMETIC` to improve readability, eliminate warnings about `EIGEN_CUDA_ARCH` not being defined. Replaced a couple C-style casts with `reinterpret_cast` for aligned loading of `half*` to `half2*`. This eliminates `-Wcast-align` warnings in clang. Although not ideal due to potential type aliasing, this is how CUDA handles these conversions internally.

* Define internal::make_unsigned for [unsigned]long long on macOS.Gravatar David Tellenbach2021-02-17
| | | | | | | | | | macOS defines int64_t as long long even for C++03 and therefore expects a template specialization internal::make_unsigned<long long>, for C++03. Since other platforms define int64_t as long for C++03 we cannot add the specialization for all cases.
