--- Comment #21 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 33315 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=33315&action=edit pr62025-2.c Possible testcase for the testsuite. Except this one only used to be miscompiled with trunk and not 4.9 branch, and unfortunately also needs -march=z900 at least, so we'd need effective-target for 64-bit s390-*-*. Perhaps not worth adding this into the testsuite.
