Default

-IPF-fma or /QIPF-fma

Floating-point multiplies and add/subtract operations are combined.
However, if you specify -mp (Linux) or /Op (Windows) and do not specifically specify this option, the default is -no-IPF-fma or /QIPF-fma-.

Description

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.
