Detailed Description

This represents 'safelen' clause in the '#pragma omp ...' directive.

#pragma omp simd safelen(4)

In this example directive '#pragma omp simd' has clause 'safelen' with single expression '4'. If the safelen clause is used then no two iterations executed concurrently with SIMD instructions can have a greater distance in the logical iteration space than its value. The parameter of the safelen clause must be a constant positive integer expression.
