Does chapel implement tail call optimisation?

Question

Chapel supports recursive function calls, but does it support tail call optimisation so that tail recursion does not use an extra stack frame?

Answer 1

I'm reasonably certain that the Chapel compiler does not implement tail recursion optimizations itself. Depending on the complexity of the function, it may be that the back-end compiler (C compiler or LLVM) would perform such optimizations on the generated code.
