[llvm-dev] Manually insert an instruction in SelectionDAG

I am trying to insert a .byte/.word in the beginning of a specific LLVM IR instruction when it prints out in assembly (the inserted ‘instruction' only appears in assembly, not in LLVM IR), and I am guessing the best way to do that is to insert it in SelectionDAG as it strips down some LLVM IR instructions when it’s lowered. Can I get some guidance on what function I should use to insert a .byte/.word in SelectionDAG so it’s printed out in assembly?

Thank you,
