The "lis" instruction is equivalent to addis rD,0,value instruction.
Definition: Add Immediate Shifted
Operation: if rA = 0 then rD " EXTS(SIMM || (16)0)
else rD " (rA) + EXTS(SIMM || (16)0)
Description: The sum (rA|0) + (SIMM || 0x0000) is placed into rD.
The addis instruction is preferred for addition because it sets few status bits. Note that addis uses the value 0, not the contents of GPR0, if rA = 0.
Have a great day,
