* 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.

* Add support for CastXML on ARM aarch64Gravatar Brad King2020-09-16
| | | | | | | | CastXML simulates the preprocessors of other compilers, but actually parses the translation unit with an internal Clang compiler. Use the same `vld1q_u64` workaround that we do for Clang. Fixes: #1979

* Remove old Clang compiler bug work-arounds. The two LLVM bugs referenced in ↵Gravatar Benoit Jacob2020-09-15
| | | | the comments here have long been fixed. The workarounds were now detrimental because (1) they prevented using fused mul-add on Clang/ARM32 and (2) the unnecessary 'volatile' in 'asm volatile' prevented legitimate reordering by the compiler.

* 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 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.

* 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.
