> Good point - I think we have to convert all codegen tests that have these function-level attributes to IR FMF and make sure that the output doesn't change. Definitely not part of this patch, but hopefully something that can be done incrementally, test-by-test.

I wonder if we couldn’t have this part of the bitcode/IR auto-upgrade: when we load a function with this attribute, we automatically add the individual flag on every instruction.
