I'm missing what you're getting at here.  Most available Fortran source 
doesn't push the limits of what gfortran or commercial compilers can do 
with in-lining.  ifort 9.1 may do as much in-lining as gfortran -O3. 
Unless you can show where it make a difference in the Polyhedron 
benchmarks, I'll hold to my opinion that there's not much in it. 
Certainly, Polyhedron benchmarks aren't constructed to help you predict 
the performance of code which is constructed so as to depend on in-lining.
