You get what you ask for. X asm constraint means any operand is allowed, which
really is not a good choice for asm statements, because compiler may build
operands which the machine does not have. X should be used in machine descriptions
only (accompanied by some predicate, asm statements don't have any).
The code should be changed to use "g" instead of "X".
