The conversion to GIMPLE does some of that, then the lowering into Low
GIMPLE and the CFG cleanups do the rest. The files you want to look at
are gimplify.c for all the conversion to GIMPLE, tree-cfg.c for the
building of the CFG and omp-low.c for the conversion into Low GIMPLE.
Documentation on the various parts of this process is a bit spotty, but
you should find details on the various links in the Getting Started
section of the GCC wiki (http://gcc.gnu.org/wiki/GettingStarted)
