摘要:
A computer system and processor for elimination of move operations include circuits that obtain a computer instruction and bypass execution units in response to determining that the instruction includes a move operation that involves a transfer of data from a logical source register to a logical destination register. Instead of executing the move operation, the transfer of the data is performed by tracking changes in data dependencies of the source and the destination registers, and assigning a physical register associated with the source register to the destination register based on the dependencies.
