The algorithm should only remove PHIs that break SSA form minimality. Since
GCC's SSA construction already produces minimal SSA form, the algorithm

Hi,
As a part of my bachelor thesis under the supervision of Honza (Jan Hubicka), I
implemented a new PHI elimination algorithm into GCC. The algorithm is
described in the following article:
Braun, M., Buchwald, S., Hack, S., Leißa, R., Mallon, C., Zwinkau, A.
(2013). Simple and Efficient
