Hi Andi,

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
