Commited.

Yes, this is a known LLVM limitation for all targets -- it can represent selection (like the C '?' ternary operator) of vectors but no machine target can actually support it yet. The temporary solution is to emit SIMD intrinsics for comparison directly. If you can somehow implement lp_bld_logic.c's lp_build_cmp() function in terms of altivec intrinsics then it should work. Another last-resource solution is to manually break the vector comparison in element-wise comparisons, but performance will suck drastically, since we use these a lot for color saturation/clamping. There are not many, but there are at least a couple other corner cases like this -- where vanilla LLVM IR isn't good enough. But I didn't spot any other in your log.
