[PATCH/committed] sim: cr16: clean up unused insn operands
Checks
Commit Message
The push/pop insns only have 2 operands, so delete unused "c".
The pushret/popret insns use 2 operands, but they don't implement the
logic directly, they call the push/pop implementations. So delete the
unused "a" & "b".
