David, I think we need to clarify why this should be done. The SPARC "random" instruction was designed at Sun Microsystems (now Oracle Corporation) for a never-released processor several years ago. For SPARC, randomness is obtained by reading a special control register. The SPARC "random" instruction was never implemented and never will be implemented. Please remove code to detect this instruction. Thanks!
