 <li>The LLVM X86 backend now supports the support SSE 4.1 instruction set, and
     the llvm-gcc 4.2 front-end supports the SSE 4.1 compiler builtins.  Various
     generic vector operations (insert/extract/shuffle) are much more efficient
     when SSE 4.1 is enabled.  The JIT automatically takes advantage of these
     instructions, but llvm-gcc must be explicitly told to use them, e.g. with

     vector code on OS's without 16-byte aligned stacks.</li>
