--- Comment #25 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-08-31 00:56:42 UTC --- I think a separate Bugzilla requesting as an enhancement such intrinsics would be certainly appropriate. I'm sure other code could exploit those. Note, in the meanwhile we could as well do the exercise of separating the operation to a C function - for unsigned long, the 32-bit and 64-bit cases would be good enough for now - coded perhaps along the lines explained at the beginning of Ch. 7 of "Hacker's Delight" and use the function for operator< (please, not inline). See which performance come out.
