Sorry, the code is a) not so easy to make public right now, and b) this particular edit has been lost in the mists of time (like I said, I wrote it slightly differently and then it was gone). But the scrollback in my terminal still has this for “proof”: sesse@gruessi:~/addie$ g++-4.8 -O2 -march=native -o addie addie.cc /tmp/ccJweT2R.s: Assembler messages: /tmp/ccJweT2R.s:82: Error: operand size mismatch for `bzhi' Sorry I couldn't be more helpful. :-) /* Steinar */
