New Revision: 358133
URL: https://svnweb.freebsd.org/changeset/base/358133
Log:
Silence a gcc warning about no return from a function that handles every
possible enum in a switch statement. I verified that this emits nothing
as expected on clang. radix relies on constant propagation to eliminate
any branching from these access routines.
