--- Comment #10 from Marek Polacek <mpolacek at gcc dot gnu.org> --- (In reply to David Binderman from comment #9) > Is a brand new warning ready for the prime time of -Wall ? The warning existed for some time already before it's been added to -Wall. > It might be a tad more conservative to implement the proposed warning > and not include it in -Wall until some time has elapsed and some user > feedback has been provided. That's what happened. And I believe few people noticed the new warning. > For instance, what effect does new flag -Wlogical-not-parentheses have > on building major packages like the Linux kernel, or Fedora, > or others ? Some of them won't build because of -Werror, I suppose, but that happens every year when we do the mass rebuilds; -Wall isn't guaranteed to be consistent from release to release. It should not have almost any false positives, and there's always the option to use -Wno-logical-not-parentheses or to wrap LHS in parens to suppress the warning.
