--- Comment #12 from Alan Modra <amodra at gmail dot com> ---
Bug reproduced on powerpc-e500v2-linux-gnuspe. The testcase needs -Os -mlra
-fstack-protector -fPIC, or you need to configure gcc so that -fPIC and
-fstack-protector are on by default. I haven't yet tested whether the lra
patch I posted for comment #1 testcase also fixes the e500 testcase.
