function contains no call instructions.
Otherwise, the local stack frame must not contain pointers,
and the assembly must confirm this fact by executing the
pseudo-instruction <code>NO_LOCAL_POINTERS</code>.
Because stack resizing is implemented by moving the stack,
the stack pointer may change during any function call:
even pointers to stack data must not be kept in local variables.
