"st 0,%0" stores the contents of register 0 at the address pointed to by
operand 0. The st insn always operates on registers and cannot take immediate
data.
There is no modifier that expands to the register prefix. Currently the only
way to produce the correct register name is to substitute a suitable register
operand.
