RECONSTRUCTION OF FLAGS AND DATA FOR IMMEDIATE FOLDING

Abstract:

In one embodiment, a processor includes a fetch logic to fetch instructions, a decode logic to decode the instructions, an execution logic to execute at least some of the instructions, and a reconstruction logic. The decode logic may identify a first instruction having a first immediate value, accumulate the first immediate value with a folded immediate value associated with a first operand of the first instruction, and prevent the first instruction from provision to the execution logic, such that the first instruction is not to be executed within the execution logic. The reconstruction logic may reconstruct one or more flags associated with a result of the first instruction. Other embodiments are described and claimed.
