Hm. This seems to suggest a straight out code generation bug in that compiler, not a failure in intrinsic detection. I'll note that there's certainly ppc64 machine with that intrinsic working (tested that on the community hydra during atomics development). So either it's a bug specific to some compiler version, or 32bit ppc. I assume there's no trivial way to get a newer compiler on that machine? Andres -- Sent from my Android device with K-9 Mail.
