Oh, there is. Since we are looking at the operands, we can process
this operand with operand modifier in the asm template.
Basically, "lock{%;} %K4 cmpxchg{<imodesuffix>}\t{%3, %1|%1, %3}",
where K modifier would print correct string from x86_print_operand,
depending on the INTVAL value of operand4.
Uros.
