ABSTRACT:
If a consumer instruction specifies a 64 bit source register comprised of results provided by two 32 bit producer instructions, the number of dependencies that must be tracked per source register can be decreased by transforming one or more of the 32 bit producer instructions so that rather than simply storing its result in a 32 bit destination register, the transformed instruction stores its result into a 64 bit logical register along with another 32 bit value held in another 32 bit register.
