--- Comment #5 from dcb <dcb314 at hotmail dot com> 2012-04-28 12:17:57 UTC --- (In reply to comment #4) > Could you give a sample? -Wlogical-op merges 2 unrelated warnings: > *) x && 2 (you would expect a boolean, not 2, so maybe x&2 was meant) > *) x<0 && x>0 (not so likely to happen) or x>=-5 || x<2 (always true) > > and it is not clear which one you are most interested in. #2 is the one I am interested in. I only discovered the other warning by accident, after 8 of the 10 warnings I checked closely. I used the Linux kernel as an example. I'd probably need to analyse more cases, in other packages too, to be sure that most of what the warning finds is #2. It seems a pretty small warning, but I guess #1 and #2 could be split up, if that helps get #2 in.
