| Abstract: | A number of integrated techniques was proposed to introduce some communication between instraction scheduling and register allocation,which increased instruction level parallelism without drastically increasing the number of spills and hence improved performance considerably.This paper introduced some typical integrated methods which was classified according to respective characteristic.And also reported some related evaluations and some new trends in the meanwhile. |

| Keywords: | instruction scheduling register allocation register pressure register spilling |
