Bug #: 53131 Summary: -Wlogical-op: ready for prime time in -Wall ? Classification: Unclassified Product: gcc Version: 4.8.0 Status: UNCONFIRMED Severity: minor Priority: P3 Component: c AssignedTo: unassig...@gcc.gnu.org ReportedBy: dcb...@hotmail.com I am somewhat surprised that -Wlogical-op isn't part of either -Wall or possibly -Wextra. I've just tried -Wlogical-op out on a build of a recent Linux kernel and 90 warnings are produced, so there is some evidence that it would be useful.
