   The language semantics can sometimes lead to poorer performance with   
   inlining. The classical example is the DAXPY function in Fortran. When   
   not compiled inline, DAXPY can take advantage of Fortran language   
   rules concerning non-overlapping of dummy and global arguments. When   
   compiled inline the overlap may be difficult to identify with   
   dependence analysis, so performance may be hurt.
