The changes are made in the patch for optimized usage of pcmpne/pcmpeq instructions.
The changes are made in the patch for optimized usage of pcmpne/pcmpeq
instructions. The xor with register to register is replaced with pcmpeq
/pcmpne instructions and for immediate check still the xori will be used.
The purpose of the change is to acheive the aggressive usage of pcmpne
/pcmpeq instructions instead of xor being used for comparison.
