Clang vs GCC for my Linux Development project

Question

I\'m in college, and for a project we\'re using C. We\'ve explored GCC and Clang, and Clang appears to be much more user friendly than GCC. As a result, I\'m wondering what

Answer 1

I use both Clang and GCC, I find Clang has some useful warnings, but for my own ray-tracing benchmarks - its consistently 5-15% slower then GCC (take that with grain of salt of course, but attempted to use similar optimization flags for both).

So for now I use Clang static analysis and its warnings with complex macros: (though now GCC's warnings are pretty much as good - gcc4.8 - 4.9).

Some considerations:

• Clang has no OpenMP support, only matters if you take advantage of that but since I do, its a limitation for me. (*****)
• Cross compilation may not be as well supported (FreeBSD 10 for example still use GCC4.x for ARM), gcc-mingw for example is available on Linux... (YMMV).
• Some IDE's don't yet support parsing Clangs output (QtCreator for example *****). EDIT: QtCreator now supports Clang's output
• Some aspects of GCC are better documented and since GCC has been around for longer and is widely used, you might find it easier to get help with warnings / error messages.

***** - these areas are in active development and may soon be supported
