Does this still apply? >=20 > The most recent FREEBSD_CC_VERSION update was the clang 4 -> clang 5 = transition: For clang, I update FREEBSD_CC_VERSION much more conservatively now, since bumping it requires everybody to do a full compiler bootstrap during buildworld. Basically only when: * A major update is imported, such as going from 4.0.0 to 5.0.0.
