摘要：A computer-implemented method includes determining that two or more instructions of an instruction stream are eligible for optimization, where the two or more instructions include a memory load instruction and a data processing instruction to process data based on the memory load instruction. The method includes merging, by a processor, the two or more instructions into a single optimized internal instruction and executing the single optimized internal instruction to perform a memory load function and a data processing function corresponding to the memory load instruction and the data processing instruction.

主权项：1. A computer-implemented method comprising: determining that two or more instructions of an instruction stream are eligible for optimization, the two or more instruction including a memory load instruction and a data processing instruction to process data based on the memory load instruction; merging, by a processor, the two or more instructions into a single optimized internal instruction, wherein the single optimized internal instruction comprises a single stored rename register identifier; storing the single optimized internal instruction in a single slot in an issue queue; and executing the single optimized internal instruction to perform a memory load function and a data processing function corresponding to the memory load instruction and the data processing instruction, the executing including executing the memory load instruction followed by the data processing instruction.
