Hi Hal, I think that it's perfectly valid to generate inline assembler and it looks 1000 times cleaner than if I tried to do this same work with selection DAG. > I hope you don't mind if I play devil's advocate here... > > Why is this so complicated that it would be messy to do, at least in part, at a lower level? I can understand needing IR-level analysis for some kinds of
