Definitely.
I built llvm/clang per instructions here:
http://clang-analyzer.llvm.org/
Than ran them like this:
scan-build -o clang ./autogen.sh
scan-build -o clang make
That produces a bunch of html in the -o-specified dierctory, clang/.
Point your browser at clang/*/index.html to view the results.
