* Simplify handling of tests that must fail to compile.Gravatar Gael Guennebaud2018-12-12
| | | | Each test is now a normal ctest target, and build properties (compiler+flags) are preserved (instead of starting a new build-dir from scratch).

| * Fix evalShardedByInnerDim for AVX512 buildsGravatar Mark D Ryan2018-12-05
| | | | | | | | | | | | | | | | | | | | | | | | evalShardedByInnerDim ensures that the values it passes for start_k and end_k to evalGemmPartialWithoutOutputKernel are multiples of 8 as the kernel does not work correctly when the values of k are not multiples of the packet_size. While this precaution works for AVX builds, it is insufficient for AVX512 builds where the maximum packet size is 16. The result is slightly incorrect float32 contractions on AVX512 builds. This commit fixes the problem by ensuring that k is always a multiple of the packet_size if the packet_size is > 8.
