Both gcc and clang can often detect tail recursive functions and implement them with plain loops with no recursive call.

I assume this is advantageous because then they can unfurl the loops and parallelize instructions across loop 'boundaries'? I wonder if there are other advantages.

Bounded stack usage is the main advantage.
