are combined. However, if you specify -mp (Linux) or /Op (Windows) and do not specifically specify this option, the default is OFF. |
This option enables the combining of floating-point multiplies and add/subtract operations.
It also enables the contraction of floating-point multiply and add/subtract operations into a single operation. The compiler contracts these operations whenever possible.
