For alias analysis, GCC uses a fairly sophisticated constraint-based
points-to analysis and complements it with type-based disambiguation.
You can read about it in the various GCC Summit proceedings over the
last 2-3 years. You can find them in http://gcc.gnu.org/wiki
I'm not sure what exactly you mean by "some basic analysis", but you
will find GCC a fairly featureful compiler. In terms of strength, GCC
is the system compiler of every Linux distribution out there, so it is
thoroughly tested and breaking it takes a bit of effort.
