As far as I'm aware the llvm-prof tool does not support path profiling data.

I am working on a Google "Summer of Code" project to improve support for 
profile guided optimisation (including path profiling).  I intend to fix 
this issue, but it is at the end of a long list of things to work on.

Alastair.
