Abstract
The present invention is a compiler optimization algorithm that reduces address computation overhead for architectures that support an auto-increment addressing mode for memory access instructions. The compiler algorithm identifies opportunities for auto-increment synthesis in a low level intermediate representation. Candidate loads and stores are transformed to use a base+displacement addressing mode (even if a base+displacement addressing mode is not supported in the target architecture) prior to instruction scheduling. After instruction scheduling, the pseudo (base+displacement) instructions are transformed back into memory operations that increment their base register operands to set up effective memory addresses.
