Abstract: The basic concept of iterative compilation is first introduced；Secondly，the evolution of iterative compilation is discussed and then the present research situation of iterative compilation is overviewed，including optimization space expression，optimization space exploration and search，and the sensitivity analysis of data input sets；Thirdly，the drawback of current iterative compilation technology is analyzed；Finally，the conclusions and the future trends of iterative compilation study are given.

Key words: iterative compilation, program optimization, compiler optimization, polyhedral model, code isolation
