No, arith_operand is just register_operand or const_imm12_operand, but comparing a const_imm12_operand with (const_int 1) should be folded into a constant (even at -O0, AFAIK). So allowing const_imm12_operand here makes no benefit. > "" > - "slt<u>i\t%0,%.,%1" > + "slt<u>%i1\t%0,%.,%1" > [(set_attr "type" "slt") > (set_attr "mode" "<X:MODE>")]) > -- Xi Ruoyao <xry...@xry111.site> School of Aerospace Science and Technology, Xidian University
