WebQuestion: ADDI adds the sign-extended 12-bit immediate to register rs1. Arithmetic overflow is ignored and the result is simply the low XLEN bits of the result. ADDI rd, rs1, 0 is used to implement the MV rd, rs1 assembler pseudo-instruction. Just wanted to know how I could go about finishing this method from the NYI line forward.
