--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
No noipa does not turn off sibcalling optimization. Or turns off the local
transformation of tail call. 
Rather noipa turns off all of the ipa pass knowledge of that function.

Tail call is a local transformation is not considered ever an ipa based one.
