--- Comment #2 from James Greenhalgh <jgreenhalgh at gcc dot gnu.org> --- Created attachment 36608 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=36608&action=edit testcasem, no arm_neon.h dependency Second testcase stripping the arm_neon.h stuff and using only GCC vector extensions. I couldn't get this to fail on s390 or i386 (two other targets which V1DF mode stuff in their back-end).
