--- Comment #7 from Martin Sebor <msebor at gcc dot gnu.org> ---
Current trunk as well as all supported GCC versions before it still emits the
same code (see below). XLC 12 on gcc111.fsffrance.org also emits a branch (see
below). Ditto for Clang.
David, in light of this and in light of comments #4 and #5, do you still
believe that GCC should change as you suggested in the Description?
