| | | | | | | | | | | | | | | and, if so, to return a vector of boolean as a result; Extend the select LLVM IR instruction to allow you to specify a result type which is a vector of boolean, in which case the result will be an element-wise selection instead of choosing one vector or the other; and Update LangRef.html to describe these changes.
