  * 01_install_FindEigen3.patch (CMake Config mode is preferred)
- Fix build for ppc64le (affects test and dependent packages, e.g.
  arpack-ng), add fix_ppc64le_always_inline_680.patch

- Update to version 3.4.0
  * Long list of changes, see
    <https://eigen.tuxfamily.org/index.php?title=3.4>.

  * eigen3-CastXML-support-for-aarch64.patch.
  * eigen3-make-sparseqr-unit-test-stable.patch.
  * eigen3-failtests-handling.patch.

  * 0001-Do-stack-allignment-on-ppc.patch.
- Minor line offset adjustments of other patches to apply cleanly.

- Update to version 3.3.9:
  * Introduce rendering Doxygen math formulas with MathJax and the
    option EIGEN_DOC_USE_MATHJAX to control this.
  * Issue 1746: Removed implementation of standard
    copy-constructor and standard copy-assign-operator from
    PermutationMatrix and Transpositions to allow malloc-less
    std::move.
  * Issue 2036: Make sure the
    find_standard_math_library_test_program compiles and doesn't
    optimize away functions we try to test for.
  * Issue 2046: Rename test/array.cpp to test/array_cwise.cpp to
    fix an issue with the C++ standard library header "array"
  * Issue 2040: Fix an issue in test/ctorleak that occured when
    disabling exceptions.
  * Issue 2011: Remove error counting in OpenMP parallel section
    in Eigen's GEMM parallelizing logic.
  * Issue 2012: Define coeff-wise binary array operators for base
    class to fix an issue when using Eigen with C++20
  * Fix an issue with Intel® MKL PARDISO support.
- Drop Remove-error-counting-in-OpenMP-parallelize_gemm.patch:
  incorporated upstream.
- Add patches to fix building and running tests:
  * eigen3-failtests-handling.patch: Simplify handling of tests
    that must fail to compile; upstream commit: 72c0bbe.
  * eigen3-make-sparseqr-unit-test-stable.patch: Make sparseqr
    test more stable to prevent random failures; patch taken from
    upstream commit
    [https://gitlab.com/libeigen/eigen/-/issues/899].
  * eigen3-googlehash-detection.patch: GoogleHash needs C++11 std
    to compile test code and be succesfully detected.
  * eigen3-fix-forward_adolc-unit-test.patch: Prevent conflict of
    std::min/max with eigen's macros by importing eigen
    test-suite's main.h header only after all system headers have
    been included.
- Setup but don't run tests due to random errors in test-suite
  itself
  * Pass EIGEN_TEST_CXX11:Bool=ON and EIGEN_TEST_OPENMP:Bool=ON to
    cmake to enable building c++11 and openmp tests.
  * export EIGEN_SEED=100 to build with fixed seed (see
    https://gitlab.com/libeigen/eigen/-/issues/2088).
  * export EIGEN_REPEAT=1 to run each test only once (default 10)
    to save time and since we use a fixed seed anyway.
  * Disable for non-86_64 archs as some unsupported tests fail for
    the others (for i586 some supported tests too, see
    https://gitlab.com/libeigen/eigen/-/issues/2092).
- Pass CMAKE_SKIP_RPATH:BOOL=OFF and
  CMAKE_SKIP_INSTALL_RPATH:BOOL=ON to cmake to fix rpath handling
  in Leap 15.2's cmake macros (doesn't hurt generally).
- Change CMAKE_BUILD_TYPE from Release to RelWithDebInfo (openSUSE
  default).

- Drop eigen_pkgconfig.patch: the includedir now needs to be
  specified relative to CMAKE_INSTALL_PREFIX, so this patch causes
  the includedir in the pkgconfig file to be erroneous
  (boo#1178139).
- Use %autosetup to automatically run through patches.

- Fix compilation error when using Eigen3 with OpenMP:
  * Remove-error-counting-in-OpenMP-parallelize_gemm.patch
