* | Initialize isometric transforms like affine transforms.Gravatar Greg Coombe2019-01-11
| | | | | | | | | | | | The isometric transform, like the affine transform, has an implicit last row of [0, 0, 0, 1]. This was not being properly initialized, as verified by a new test function.
* | PR 571: Implements an accurate argument reduction algorithm for huge inputs ↵Gravatar Gael Guennebaud2019-01-14

This makes both the small and huge argument cases faster because: - for small inputs this removes the last pselect - for large inputs only the reduction part follows a scalar path, the rest use the same SIMD path as the small-argument case.

| | * Remove reinterpret_cast from AVX512 complex implementationGravatar Mark D Ryan2019-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The reinterpret_casts used in ptranspose(PacketBlock<Packet8cf,4>&) ptranspose(PacketBlock<Packet8cf,8>&) don't appear to be working correctly. They're used to convert the kernel parameters to PacketBlock<Packet8d,T>& so that the complex number versions of ptranspose can be written using the existing double implementations. Unfortunately, they don't seem to work and are responsible for 9 unit test failures in the AVX512 build of tensorflow master. This commit fixes the issue by manually initialising PacketBlock<Packet8d,T> variables with the contents of the kernel parameter before calling the double version of ptranspose, and then copying the resulting values back into the kernel parameter before returning.

| | | | | | | | | | | | | | This new version achieve same speed for SSE/AVX, and is slightly faster with FMA. Guarantees are as follows: - no FMA: 1ULP up to 3pi, 2ULP up to sin(25966) and cos(18838), fallback to std::sin/cos for larger inputs - FMA: 1ULP up to sin(117435.992) and cos(71476.0625), fallback to std::sin/cos for larger inputs

* PR560: Fix the AVX512f only buildsGravatar Mark D Ryan2019-01-03
| | | | | | | | | | | | | | | Commit c53eececb0415834b961cb61cd466907261b4b2f introduced AVX512 support for complex numbers but required avx512dq to build. Commit 1d683ae2f5a340a6e2681c8cd0782f4db6b807ea fixed some but not, it would seem all, of the hard avx512dq dependencies. Build failures are still evident on Eigen and TensorFlow when compiling with just avx512f and no avx512dq using gcc 7.3. Looking at the code there does indeed seem to be a problem. Commit c53eececb0415834b961cb61cd466907261b4b2f calls avx512dq intrinsics directly, e.g, _mm512_extractf32x8_ps and _mm512_and_ps. This commit fixes the issue by replacing the direct intrinsic calls with the various wrapper functions that are safe to use on avx512f only builds.
