(SPARC) #pragma unroll (unroll_factor)

This pragma accepts a positive constant integer value for the argument unroll_factor. The pragma applies to the next for loop within the current block. For unroll factor other than 1, this directive serves as a suggestion to the compiler that the specified loop should be unrolled by the given factor. The compiler will, when possible, use that unroll factor. When the unroll factor value is 1, this directive serves as a command which specifies to the compiler that the loop is not to be unrolled. The compiler takes advantage of this information at optimization level of 3 or above.
