Mark D Ryan e79c5149bf Fix AVX512 implementations of psqrt

This commit fixes the AVX512 implementations of psqrt in the same
way that 3ed67cb0bb
 fixed the AVX2 version of this function.  The
AVX512 versions of psqrt incorrectly return -0.0 for negative
values, instead of NaN.  Fixing the issues requires adding
some additional instructions that slow down the algorithms.  A
similar test to the one used in 3ed67cb0bb
 shows that the
corrected Packet16f code runs at 73% of the speed of the existing code,
while the corrected Packed8d function runs at 68% of the original.

fix md5sum of lapack_addons

2018-06-15 14:21:29 +02:00

Simplify handling and non-splitted tests and include split_test_helper.h instead of re-generating it. This also allows us to modify it without breaking existing build folder.

2018-07-16 18:55:40 +02:00

DIsable static assertions only when necessary and disable double-promotion warnings in that case as well

2018-07-26 00:01:24 +02:00

Removed several shadowing types and use global Index typedef everywhere

.hgeol

Added a pattern which forces LF line endings for *.sh files.

.hgignore

ignore all *build* sub directories

CMakeLists.txt

bug #1572 : use c++11 atomic instead of volatile if c++11 is available, and disable multi-threaded GEMM on non-x86 without c++11.

COPYING.GPL

there's no reason why we should follow the FSF's stupid recommendation for the naming of these files, right? This could give the wrong impression that Eigen is only GPL-licensed.
