Abstract
A processor includes an instruction fetch circuit to retrieve instructions from memory, and a decode unit circuit to decode retrieved instructions. The decode unit circuit identifies a shift instruction, accumulates a shift folded immediate value to track a number of bit positions shifted for a source register, and prevents the shift instruction from allocation to an execution unit of the processor.
