I believe g95 came into GCC as gfortran in the tree-ssa branch (under cvs). At one time, one could check on-line the branches under subversion. I cannot find a tree-ssa branch under git with the on-line repository. I suspect this dates back to g95, and falls under the development where one assumes only correctly written standard conforming Fortran is fed into gfortran.
