--- Comment #6 from Lang Hames <lhames at gmail.com> ---
The proper place to catch this would be in the module verifier, which we do run
on every module in LLI. Unfortunately it doesn't seem to catch this bug. I
suspect that target-features attributes are opaque to the verifier, so it can't
recognize the incompatibility. I've filed https://llvm.org/PR52156 to
investigate making this detectable, but it's outside my wheelhouse -- we'll
have to wait for someone else to pick this up and run with it.
