d213a0bcea DenseStorage safely copy/swap. 
Fixes #2229.

For dynamic matrices with fixed-sized storage, only copy/swap
elements that have been set.  Otherwise, this leads to inefficient
copying, and potential UB for non-initialized elements.

543e34ab9d Re-implement move assignments. 
The original swap approach leads to potential undefined behavior (reading
uninitialized memory) and results in unnecessary copying of data for static
storage.

Here we pass down the move assignment to the underlying storage.  Static
storage does a one-way copy, dynamic storage does a swap.

Modified the tests to no longer read from the moved-from matrix/tensor,
since that can lead to UB. Added a test to ensure we do not access
uninitialized memory in a move.

Fixes: #2119

$ clang++ -O3 bench/bench_move_semantics.cpp -I. -std=c++11 \
        -o bench_move_semantics

$ ./bench_move_semantics
float copy semantics: 1755.97 ms
float move semantics: 55.063 ms
double copy semantics: 2457.65 ms
double move semantics: 55.034 ms

efd9867ff0 bug #1746: Removed implementation of standard copy-constructor and standard copy-assign-operator from PermutationMatrix and Transpositions to allow malloc-less std::move. Added unit-test to rvalue_types 2019-09-24 11:09:58 +02:00

82f0ce2726 Get rid of EIGEN_TEST_FUNC, unit tests must now be declared with EIGEN_DECLARE_TEST(mytest) { /* code */ }. 
This provide several advantages:
- more flexibility in designing unit tests
- unit tests can be glued to speed up compilation
- unit tests are compiled with same predefined macros, which is a requirement for zapcc
