(plus, if it was really 4.2, it'd be a 5+ year old version) Not to mention, LLVM 2.9 is pretty old as well. Plus, you know, without explaining what options were used, it's impossible to tell anything about anything.

It's really GCC 4.2, not LLVM. I used -O2 for GCC and clang and -O (which runs LLVM in -O2 mode) for Rust. Updated the post to mention the options.

Edit: Added clang 3.1, trunk 149587. Over 2.9 it has some improvements, some regressions.

Great, thanks!
