--- Comment #51 from Manuel López-Ibáñez <manu at gcc dot gnu.org> 2011-02-06 20:48:38 UTC --- BTW, anyone interested in fixing this may want to take a look at the newest proposal for improving Wuninitialized in Clang: http://lists.cs.uiuc.edu/pipermail/cfe-dev/2011-February/013170.html They specifically mention the issues of GCC's implementation and how they plan to address them. Nevertheless, there are several problems for implementing Clang's approach in GCC. First, they prefer to have false positives (a false warning) than false negatives (a missed correct warning), whereas GCC tries as hard as possible to not warn when it shouldn't. Second, their proposal makes use of the static analysis checker build into clang, which GCC does not have (and probably never will) in its front-ends.
