The study and implementation of architecture-dependent optimization in GCC

摘要

Because of lack of architecture-dependent optimization in GCC, an optimization method that directly analyzes the assembly code generated by GCC is adopted in this paper. First, the structure of GCC and the Intel Pentium processor is introduced. Then, the utilization of Pentium's attributes in GCC is discussed with a case study. Finally, a support tool for architecture-dependent optimization for a Pentium processor in GCC, the postpass optimizer, is described.
