Abstract
Embodiments of an invention for a physical register table for eliminating move instructions are disclosed. In one embodiment, a processor includes a physical register file, a register allocation table, and a physical register table. The register allocation table is to store mappings of logical registers to physical registers. The physical register table is to store entries including pointers to physical registers in the mappings. The number of entry locations in the physical register table is less than the number of physical registers in the physical register file.
