Actual state fixes previous bugs but the Eigen library is still included in the sources. As soon as possible, I change it to project dependency to install. |

Reimplementation of current FPU stack analysis. The new design supports dependencies of CFG for functions and BasicBlocks. Optimization uses 3rd party library Eigen for calculation with matrices. The new component also includes a set of unit tests.
