--- Comment #9 from pnewell at cs dot cmu.edu 2011-12-03 03:29:03 UTC --- I just tested on my Linux box and I am getting the results you suggest for -O2 and -O3. It is finding issues with -O, -Os, and -O1, but I think that is my problem (barking on the inlined destructor). However, -O0 still gives me the -fno-inline warnings I just got your email about "Because there is code to explicitly turn off the warning for -O0 but not when using the pragma". I've never seen any documentation about the pragma GCC diagnostic warning having different actions than just on the compile line. Is there any more info on this? Please pardon my questioning this, but does that seem right? I would expect same behavior between a compile line -Winline and a pragma in the code stating "#pragma GCC diagnostic warning "-Winline"? Thanks, Paul
