Author: jeff Date: Wed Feb 19 22:34:22 2020 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.
