摘要
An approach is provided in which a mapper control unit receives dispatch information corresponding to an instruction that targets a first field in a first register and a second field in a second register, the first register being a first register type and the second register being a second register type. As such, the mapper control unit selects a history buffer entry in a history buffer that is adapted to concurrently store content corresponding to the first register type and the second register type. In turn, the mapper control unit stores first content from the first register's targeted first fields and second content from the second register's targeted second fields into the selected history buffer entry.
