Yes.  There are many files that deal with this.

The CFG is built in gcc/tree-cfg.c, various other files have modules
related to CFG maintenance and traversal.  Dataflow is done on SSA in
the gimple IL (tree-into-ssa.c, tree-ssa.c, tree-outof-ssa.c and
friends) and using traditional dataflow in the RTL IL (df-*.c).
