--- Comment #7 from Manuel López-Ibáñez <manu at gcc dot gnu.org> 2012-05-07 13:42:10 UTC --- In fact, the main show-stopper for adding -Wlogical-op to -Wextra (or -Wall) is PR40172, which was the reason it was moved out of -Wextra in the first place. Someone would need to find a way to avoid warning in that case, for example using the new tracking macro expansion infrastructure.
