While there is lots to be said for the maintainability of intrinsics, I have found inline assembly to be significantly better for performance. And this is precisely because it inhibits the compiler from blindly performing 'optimizations' in the section of code you've already optimized. This thread offers an example and some numbers: http://software.intel.com/en-us/forums/topic/480004 |
