no, tree-level induction variable analysis is in tree-scalar-evolution.c. What you are looking for most likely is simple_iv function (or if you are adventurous and want to handle non-affine induction variables or evolutions in several loops at once as well, analyze_scalar_evolution and instantiate_parameters functions).
