Propagate all five matrix template parameters to members and temporaries of decomposition classes. One particular advantage of this is that decomposing matrices with max sizes known at compile time will not allocate.
...
NOTE: The ComplexEigenSolver class currently _does_ allocate (line 135 of Eigenvalues/ComplexEigenSolver.h), but the reason appears to be in the implementation of matrix-matrix products, and not in the decomposition itself.
The nomalloc unit test has been extended to verify that decompositions do not allocate when max sizes are specified. There are currently two workarounds to prevent the test from failing (see comments in test/nomalloc.cpp), both of which are related to matrix products that allocate on the stack.

you can still use EIGEN_DONT_ALIGN to do both at once.

Added initial NEON support, most tests pass however we had to use some hackish workarounds
...
as gcc on ARM (both CodeSourcery 4.4.1 used and experimental 4.5) fail to
ensure proper alignment with __attribute__((aligned(16))). This has to be
fixed upstream to remove the workarounds.
