--- Comment #3 from Chengnian Sun <chengniansun at gmail dot com> --- Thanks, Marek. May I ask another question on the Gcc optimizations and warnings? Is there a policy that the warnings should be independent of the optimization levels? That is, for all optimization levels, Gcc should always emit consistent warnings. I know that Clang has such a policy. But based on what I have observed on Gcc, it seems that Gcc does not have this policy.
