--- Comment #1 from Alan Modra <amodra at gmail dot com> ---
True, ld will do this.  However, the optimization is relying on gcc to generate
code that can be optimized this way..  So I'm assuming the example code was
from llvm or assembly.

gcc ensures that the optimization is valid by adding a dependency on r2 to the
low part of the address calculation.
