Thanks for the comments, patch is improved
isStringAttribute() check removed, the attribute is always a string in this case or "null" so the check is not needed.
Function level the attribute is now only change when needed, so as the function level attribute is expected to be rare I hope the performance won't be impacted by the patch.
I kept the "tri-state" logic because of the emitted functions. Introducing a "branch-target-enforcement-disabled" attribute seems even more confusing for me.
