iPhone GCC / LLVM GCC or LLVM? http://stackoverflow.com/questions/3739783/iphone-gcc-llvm-gcc-or-llvm compiler over GCC up to 60 faster in certain cases . There are additional improvements that can be made by using the Clang parser with the LLVM compiler. Watch Session 312 What's New in the LLVM Compiler for more on this as well as the sessions.. of my applications but it wasn't a rigorous test so consider that only anecdotal evidence. My recommendation is to use Clang LLVM LLVM Compiler 1.5 if you can for faster build times more performant applications and much better compiler errors. If.. build times more performant applications and much better compiler errors. If you use C code or something else that the Clang parser cannot handle right now use LLVM GCC to still get the performance benefits in your compiled application. Go to GCC..
