In fact I just copied the piece of code from the `AArch64TargetLowering::LowerCall` function.
By doing this I believe I just make things consistent between whether the TCO could take place and when TCO is done.

Now a noob question related to your comments.
I read that there is now a clang attribute to mark calls as musttail. Isn't these checks necessary for the case where user can ask for a tail call when it's not possible?
