The experimental Vector LLVM branch allows some additional vector operations (e.g., compare, select, pack, and unpack) and also has support for arbitrary-length vectors. Mainline vector support continues to improve, and many of the additional "packed" operations supported by Vector LLVM will eventually be part of mainline. Right now I am working on adding compare and select to mainline and hope to get that checked in soon.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Rob</DIV><BR><DIV> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Robert L.
