Comment #25: I don't understand your logic, what does attribute((noreturn))
have to do with a stack frame?
The only valid reasons for generating a stack frame are alloca() or needed
stack realignment. Other functions calls, either returning or noreturn don't
need a frame.
Note that attribute((noreturn)) functions normally don't trigger a stack frame.
That example function was actually carefully minimized from a larger real-world
function. If you change the content of the loop, the stack frame won't be
generated. It looks like there is something rotten in gcc.
