3.6.1.7 DIVA Option

The -mdiva option enables the use of routines that use the DIVA module to perform integer hardware divisions, shifts and rotates on devices that implement this module. This is the default operation for these devices if this option is not used. See Division, Shift and Modulo Operations for more information.

The -mno-diva form of this option disables use of these routines, having these operations instead performed by conventional library routines that will be larger and slower than the DIVA routines.
