We're looking at how to handle masked vector operations in architectures like Knight's Corner. In our case, we have to translate from a fully vectorized IR that has mask support to llvm IR which does not have mask support. For non-trapping instructions this is fairly straightforward: ; Input t1 = add t2, t3, mask ; llvm IR -- assuming we want zeros in the false positions, which is not
