Atomic instructions from the A extension like LR/SC and AMO* access memory so they should be treated as load/store. In addition, AMO* instructions perform read-modify-write operations, they should have both a source and a destination operands to comply with DR's IR convention. We make the destination an implicit operand as they are identical to the source.
