Unfortunately, no.  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,=20
and falls under the development where one assumes only correctly
written standard conforming Fortran is fed into gfortran.=
