title: Clang vs GCC - which produces faster binaries?
body: <p>I'm currently using GCC, but I discovered Clang recently and I'm pondering switching. There is one deciding factor though - quality (speed, memory footprint, reliability) of binaries it produces - if <code>gcc -O3</code>can produce a binary that runs 1% faster, or Clang binaries take up more memory or just fail due to compiler bugs, it's a deal-breaker.</p>
  <p>Clang boasts better compile speeds and lower compile-time memory footprint than GCC, but I'm really interested in benchmarks/comparisons of resulting compiled software - could you point me to some pre-existing resources or your own benchmarks?</p>
