# Kite program code
#   1. The first instruction starts at PC = 4. PC = 0 is reserved as invalid.
#   2. To terminate the program, let the next PC naturally go out of range.
#   3. All the instructions and labels are case-insensitive.
#   4. The program code supports only the following list of instructions
#      (sorted by alphabetical order in each type).
#      R-type: add, and, div, divu, mul, or, rem, remu, sll, sra, srl, sub, xor
#      I-type: addi, andi, jalr, ld, slli, srai, srli, ori, xori
#      S-type: sd
#      SB-type: beq, bge, blt, bne
#      U-type: lui
#      UJ-type: jal
#      No-type: nop

loop:   beq  x11, x0,  exit
        remu x5,  x10, x11
        add  x10, x11, x0
        add  x11, x5,  x0
        beq  x0,  x0,  loop
exit:   sd   x10, 2000(x0)
