http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39246 --- Comment #5 from Richard Guenther <rguenth at gcc dot gnu.org> 2011-02-25 14:51:22 UTC --- At what point does the direct access to IMAGPART<retval> appear? That looks like the bug. Why isn't a temporary used for this? Does s390 return the complex number in memory?
