R1 = R2 + R3
   = -333 + 117 = -216

INSTRUCTION 1: 0x04e12800
R7 = R1 + R5
   = -216 + 10000 = 9784

INSTRUCTION 2: 0x0a870000
R20 = R7 - R0
   = 9784 - 5 = 9779

INSTRUCTION 3: 0x0fd42800
R30 = R20 * R5
   = 9779 * 10000 = 97790000

R31 = R30 << 4
   = 97790000 << 4 = 1564640000

R10 = R31 | R8
   = 1564640000 | 12 = 1564640012

R25 = R10 / R3
   = 1564640012 / 117 = 13372991

INSTRUCTION 7: 0x2579e800
R11 = R25 ^ R29
   = 13372991 ^ -33 = -13372960
