--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
GCC 11 reports the uninitialized reads either way, at all optimization levels
(including -O0). It looks like r239785 was the first revision when GCC started
warning at -O0 although that revision just changed the xtensa target so I'm not
sure if that's relevant. Similarly, bisection indicates r177670 started
warning with optimization, and that revision is again unrelated to this.
Either way, GCC now warns so this can be resolved as fixed.
