All of the mesa demos work with and without llvm.

I don't actually have piglit - it was always a pain with cmake to get it 
to build on my old 32bit lfs with xorg/mesa installed under home.

I do now have a new 64bit clfs build with everything in normal places - 
so maybe I'll give it a go on that - but I don't know how to use it as such.

Even though it's "new" clfs uses gcc 4.6.3 so on there g++ is actually 
too old to build your tree - without changing some friends .... to 
friends class ...

I don't know when I'll get time to learn piglit but for now here's 
working and not nexuiz.
