3.4.15 –depend[={yes|no}]

Analyze loops for data dependencies and do loop restructuring.

Dependence analysis is enabled with -depend or -depend=yes. The analysis is disabled with -depend=no, which is the compiler default.

This option will raise the optimization level to O3 if no optimization level is specified, or if it is specified less than O3. -depend is also included with -fast, -autopar and -parallel. Note also that specifying an optimization level -O3 or higher automatically adds -depend. (See the Fortran Programming Guide.)
