Would it be more accurate to say it didn't have a functional
difference? Did we rule out that it might have made a difference in
code gen?

I guess I wouldn't be surprised if the older non-LTO toolchains didn't
make use of it anyway. So, maybe there is no difference in code gen.

With LTO the linker is hopefully smarter about auto-inlining anyhow.
