[LLVMdev] llvm profiling

I'd like to get some runtime profile data on my code using LLVM.  The  
various -insert-X-profiling passes seem to add the profiling  
instrumentation to the code, but how do I actually generate profiling  

It seems like utils/profile.pl can do this, but it uses profile_rt.so  
which doesn't exist.  I can manually compile the runtime directory  
using make install-bytecode, but it doesn't generate the necessary  
file either.  I'm wondering why the root makefile doesn't even compile  
the runtime directory to begin with.  Is there another way to go about  

I'm using llvm-2.3 and llvm-gcc-4.2.1.
