--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The reason is that gen_umaddditi4 is called with the same pseudo as operands[0]
and operands[3] and so gen_maddlddi4 overwrites its low half before
gen_umadddi4_highpart{,_le} uses it.
We could create a temporary if some overlap is mentioned, or can create it
unconditionally and let later optimizations deal with it.
