* Fixing a CUDA / P100 regression introduced by PR 181Gravatar Deven Desai2020-08-20
| | | | | | PR 181 ( https://gitlab.com/libeigen/eigen/-/merge_requests/181 ) adds `__launch_bounds__(1024)` attribute to GPU kernels, that did not have that attribute explicitly specified. That PR seems to cause regressions on the CUDA platform. This PR/commit makes the changes in PR 181, to be applicable for HIP only

* Replace the call to int64_t in the blasutil test by explicit typesGravatar David Tellenbach2020-08-14
| | | | | | | | | Some platforms define int64_t to be long long even for C++03. If this is the case we miss the definition of internal::make_unsigned for this type. If we just define the template we get duplicated definitions errors for platforms defining int64_t as signed long for C++03. We need to find a way to distinguish both cases at compile-time.

* Fix StlDeque for GCC 10Gravatar David Tellenbach2020-07-29

* Fix bfloat16 castsGravatar David Tellenbach2020-07-23
| | | | | | | If we have explicit conversion operators available (C++11) we define explicit casts from bfloat16 to other types. If not (C++03), we don't define conversion operators but rely on implicit conversion chains from bfloat16 over float to other types.
* Revert change that made conversion from bfloat16 to {float, double} implicit.Gravatar Rasmus Munk Larsen2020-07-22
| | | | Add roundtrip tests for casting between bfloat16 and complex types.

* Faster conversion from integer types to bfloat16Gravatar Niels Dekker2020-07-22
| | | | | | Specialized `bfloat16_impl::float_to_bfloat16_rtne(float)` for normal floating point numbers, infinity and zero, in order to improve the performance of `bfloat16::bfloat16(const T&)` for integer argument types. A reduction of more than 20% of the runtime duration of conversion from int to bfloat16 was observed, using Visual C++ 2019 on Windows 10.

* Avoid undefined behavior by union type punning in float_to_bfloat16_rtneGravatar Niels Dekker2020-07-14
| | | | | | | | Use `numext::as_uint`, instead of union based type punning, to avoid undefined behavior. See also C++ Core Guidelines: "Don't use a union for type punning" https://github.com/isocpp/CppCoreGuidelines/blob/v0.8/CppCoreGuidelines.md#c183-dont-use-a-union-for-type-punning `numext::as_uint` was suggested by David Tellenbach

* 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" ```
