N.b.: if you try to livepatch/trace such a leaf function without
global dependencies, it will crash if that function got called with
a different TOC value. Hence this whole testing.
You may alternatively try my gcc patch ;-)
Another caveat is functions with stack arguments (>8 args, varargs).
My code needs special precautions then because of the return helper.
