I'm not sure what you mean by that?
By awkward I mean that instruction selection should just select instructions, that is, map generic instructions to native ones and do nothing more. If there is no more or less direct mapping, then the instruction should've been lowered prior to instruction selection, potentially creating some optimization opportunities.
