About two months ago I wrote an article about the analysis of GCC using PVS-Studio. The idea of the article was as follows: GCC warnings are great, but they’re not enough. As proof of my words I showed errors that PVS-Studio was able to find the GCC code. A number of readers have noticed that the quality of the GCC code, and its diagnosis, aren’t really great; while Clang compiler is up to date, of high quality, and fresh. In general Clang is awesome! Well, apparently, it’s time to check LLVM project.
