Metadata in LLVM back-end
Hi all,
Currently metadata (other than debug info) can be attached to IR
instructions but disappears during DAG selection.
My question is why we do not keep the metadata during code lowering and
then attach to MachineInstr, just as for IR instructions? Is there any
technical challenge, or is it only because nobody wants to do so?
Thanks for your help,
Best,
