- Update to version 3.3.8:
* General bug fixes:
- Issue #1995: Fix a failure in the GEBP kernel when using
small L1 cache sizes, OpenMP and FMA.

- Issue #1788: Fix rule-of-three violations inside the stable
modules. This fixes deprecated-copy warnings when compiling
with GCC>=9. Also protect some additional Base-constructors
from getting called by user code code (Issue #1587)
- Issue #1796: Make matrix squareroot usable for Map and Ref
types.
- Issue #1281: Fix AutoDiffScalar's make_coherent for nested
expression of constant ADs.
- Issue #1761: Fall back is_integral to std::is_integral in
c++11 and fix internal::is_integral with
MSVC 2013 and older.
- Issue #1741: Fix self-adjoint*matrix, triangular*matrix, and
triangular^1*matrix with a destination having a non-trivial
inner-stride.
- Issue #1741: Fix SelfAdjointView::rankUpdate and product to
triangular part for destination with non-trivial inner
stride.
- Issue #1741: Fix C.noalias() = A*C; with C.innerStride()!=1.
- Issue #1695: Fix a numerical robustness issue in BDCSVD.
- Issue #1692: Enable enum as sizes of Matrix and Array.
- Issue #1689: Fix used-but-marked-unused warning.
- Issue #1679: Avoid possible division by 0 in complex-schur.
- Issue #1676: Fix C++17 template deduction in DenseBase.
- Issue #1669: Fix PartialPivLU/inverse with zero-sized
matrices.
- Issue #1557: Fix RealSchur and EigenSolver for matrices with
only zeros on the diagonal.
* Performance related fixes:
- Issue #1562: Optimize evaluation of small products of the
form s*A*B by rewriting them as: s*(A.lazyProduct(B)) to
save a costly temporary. Measured speedup from 2x to 5x...
- Fix performance issue with SimplicialLDLT for complexes
coefficients.
* Misc fixes:
- Fix QuaternionBase::cast for quaternion map and wrapper.
- Fix case issue with Lapack unit tests.
- Fix possible conflict with an externally defined "real" type
when using gcc-5.
- Provide numext::[u]int{32,64}_t.
- Initialize isometric transforms like affine transforms.
- Change typedefs from private to protected to fix MSVC
compilation.
- Fix compilation of FFTW unit test.
- Fix compilation of BLAS backend and frontend.
- Fix real/imag namespace conflict.
- Avoid throwing in destructors.
- Fix precision issue in SelfAdjointEigenSolver.h
- Make digits10() return an integer.
- Use pade for matrix exponential also for complex values.
- Cast Index to RealScalar in SVDBase to fix an issue when
RealScalar is not implicitly convertible to Index.
- Provide EIGEN_HAS_C99_MATH when using MSVC.
- Various fixes in polynomial solver and its unit tests.
- nd 4415d4e2d: Extend polynomial solver unit tests to
complexes.
- Automatically switch between EigenSolver and
ComplexEigenSolver, and fix a few Real versus Scalar issues.
- Enable construction of Ref from a runtime
vector.
- Fix a problem of old gcc versions having problems with
recursive #pragma GCC diagnostic push/pop.
- Fix compilation with expression template scalar type.
- Backport AVX512 implementation to 3.3.
- Fix StlDeque compilation issue with GCC 10.
- Avoid false-positive test results in non-linear optimization
tests.
- Fix undefined behaviour caused by uncaught exceptions in OMP
section of parallel GEBP kernel.
- Fix a bug with half-precision floats on GPUs.
* Fixed warnings:
- Fix some maybe-uninitialized warnings in AmbiVector.h and
test bdcsvd.
- Silent cmake warnings in Lapack CMakeLists.txt.
- Rename variable which shadows class name in Polynomials
module.
- Workaround gcc's alloc-size-larger-than= warning in
DenseStorage.h.
- Hide some unused variable warnings in g++8.1 in Tensor
contraction mapper.
- Fix gcc 8.1 warning: "maybe use uninitialized" in std tests.
- Fix always true warning with gcc 4.7in test numext.
- Fix nonnull-compare warning in test geo_alignedbox.
- Disable ignoring attributes warning in vectorization logic
test.
- Fix a gcc7 warning about bool * bool in abs2 default
implementation.
- Fix a warning in SparseSelfAdjointView about a branch
statement always evaluation to false.
- Minor rebase of patches to fix offsets.
- Specify relative path to includedir as option to cmake as it
only accepts paths relative to CMAKE_INSTALL_PREFIX now.
- Drop Group tags.
