R1 = R2 + R3
   = -16384 + -8192 = -24576

INSTRUCTION 1: 0x04e12800
R7 = R1 + R5
   = -24576 + -2048 = -26624

INSTRUCTION 2: 0x0a870000
R20 = R7 - R0
   = -26624 - -65536 = 38912

INSTRUCTION 3: 0x0fd42800
R30 = R20 * R5
   = 38912 * -2048 = -79691776

INSTRUCTION 4: 0x17fe0100
R31 = R30 << 4
   = -79691776 << 4 = -1275068416

INSTRUCTION 5: 0x215f4000
R10 = R31 | R8
   = -1275068416 | -256 = -256

INSTRUCTION 6: 0x132a1800
R25 = R10 / R3
   = -256 / -8192 = 0

INSTRUCTION 7: 0x2579e800
R11 = R25 ^ R29
   = 0 ^ 2048 = 2048
