There are some embedded applications where profiling can be
significant in code generation. The real implementation problem is the
evaluation of when to ignore the profile information. In cases where
in some code sections information from profiling shows that little can
be gained also identifies the area where performance may be further
sacrificed in exchange for performance in a critical section.
