Abstract: In processor architectures such as MIPS, ALPHA, SPARC and PowerPC, indirect addressing mode is always adopted to access global variables and static ones. Since the addresses of these variables and the corresponding values are in different data sections in the corresponding binary file, the data locality of the program will be very poor. As a result, accessing the read only addresses of these variables every time tends to result in non-trivial redundant data cache miss memory accesses. Moreover, such indirect addressing mode will generate two sequential load instructions which have data dependences between them. As a result, the amount of instruction level parallelism (ILP) of the program will be decreased. The authors present an address register promotion nethod based on feedbacks (ARPF) to solve the above problems. ARPF algorithm reduces the redundant accesses to the read only addresses of the global variables and static ones, increases the amount of instruction level parallelism of a program, and avoids the performance declines due to the increase in register pressure caused by register promotion. The algorithm has been implemented in the Loongson compiler for MIPS architecture. Experiments on SPEC CPU2000INT benchmarks are conducted to show that ARPF can improve the performance of all benchmarks by 1%~6%.
