Although I don't know about x86_64 assembly, I know x86 and I wonder
how this patch would do anything. I would personnaly have written something
more like :

+    movzl %eax,%rax

Once again, I may be wrong, but I really don't understand at all then.
Could you please either confirm or detail a bit more ?

thanks in advance,
Willy
