* Allow implicit conversion from bfloat16 to float and doubleGravatar Niels Dekker2020-07-11
| | | | | | Conversion from `bfloat16` to `float` and `double` is lossless. It seems natural to allow the conversion to be implicit, as the C++ language also support implicit conversion from a smaller to a larger floating point type. Intel's OneDLL bfloat16 implementation also has an implicit `operator float()`: https://github.com/oneapi-src/oneDNN/blob/v1.5/src/common/bfloat16.hpp

* Fix tensor casts for large packets and casts to/from std::complexGravatar Antonio Sanchez2020-06-30
| | | | | | | | | | | | | The original tensor casts were only defined for `SrcCoeffRatio`:`TgtCoeffRatio` 1:1, 1:2, 2:1, 4:1. Here we add the missing 1:N and 8:1. We also add casting `Eigen::half` to/from `std::complex<T>`, which was missing to make it consistent with `Eigen:bfloat16`, and generalize the overload to work for any complex type. Tests were added to `basicstuff`, `packetmath`, and `cxx11_tensor_casts` to test all cast configurations.
* Fix packetmath_1 float tests for arm/aarch64.Gravatar Antonio Sanchez2020-06-24
| | | | | | | | | | | | | | | | | | | Added missing `pmadd<Packet2f>` for NEON. This leads to significant improvement in precision than previous `pmul+padd`, which was causing the `pcos` tests to fail. Also added an approx test with `std::sin`/`std::cos` since otherwise returning any `a^2+b^2=1` would pass. Modified `log(denorm)` tests. Denorms are not always supported by all systems (returns `::min`), are always flushed to zero on 32-bit arm, and configurably flush to zero on sse/avx/aarch64. This leads to inconsistent results across different systems (i.e. `-inf` vs `nan`). Added a check for existence and exclude ARM. Removed logistic exactness test, since scalar and vectorized versions follow different code-paths due to differences in `pexp` and `pmadd`, which result in slightly different values. For example, exactness always fails on arm, aarch64, and altivec.
* Add missing Packet2l/Packet2ul ops for NEON.Gravatar Antonio Sanchez2020-06-22
| | | | | | | | | | | | | | | | | | | | | | | | | | The current multiply (`pmul`) and comparison operators (`pcmp_lt`, `pcmp_le`, `pcmp_eq`) are missing for packets `Packet2l` and `Packet2ul`. This leads to compile errors for the `packetmath.cpp` tests in clang. Here we add and test the missing ops. Tested: ``` $ aarch64-linux-gnu-g++ -static -I./ '-DEIGEN_TEST_PART_9=1' '-DEIGEN_TEST_PART_10=1' test/packetmath.cpp -o packetmath $ adb push packetmath /data/local/tmp/ $ adb shell "/data/local/tmp/packetmath" $ arm-linux-gnueabihf-g++ -mfpu=neon -static -I./ '-DEIGEN_TEST_PART_9=1' '-DEIGEN_TEST_PART_10=1' test/packetmath.cpp -o packetmath $ adb push packetmath /data/local/tmp/ $ adb shell "/data/local/tmp/packetmath" $ clang++ -target aarch64-linux-android21 -static -I./ '-DEIGEN_TEST_PART_9=1' '-DEIGEN_TEST_PART_10=1' test/packetmath.cpp -o packetmath $ adb push packetmath /data/local/tmp/ $ adb shell "/data/local/tmp/packetmath" $ clang++ -target armv7-linux-android21 -static -mfpu=neon -I./ '-DEIGEN_TEST_PART_9=1' '-DEIGEN_TEST_PART_10=1' test/packetmath.cpp -o packetmath $ adb push packetmath /data/local/tmp/ $ adb shell "/data/local/tmp/packetmath" ```
* Added missing NEON pcasts, update packetmath tests.Gravatar Antonio Sanchez2020-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | The NEON `pcast` operators are all implemented and tested for existing packets. This requires adding a `pcast(a,b,c,d,e,f,g,h)` for casting between `int64_t` and `int8_t` in `GenericPacketMath.h`. Removed incorrect `HasHalfPacket` definition for NEON's `Packet2l`/`Packet2ul`. Adjustments were also made to the `packetmath` tests. These include - minor bug fixes for cast tests (i.e. 4:1 casts, only casting for packets that are vectorizable) - added 8:1 cast tests - random number generation - original had uninteresting 0 to 0 casts for many casts between floating-point and integers, and exhibited signed overflow undefined behavior Tested: ``` $ aarch64-linux-gnu-g++ -static -I./ '-DEIGEN_TEST_PART_ALL=1' test/packetmath.cpp -o packetmath $ adb push packetmath /data/local/tmp/ $ adb shell "/data/local/tmp/packetmath" ```

* 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`.

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.
