--- Comment #2 from Richard Guenther <rguenth at gcc dot gnu.org> 2012-04-20 09:24:06 UTC --- Btw, see how I fixed 2012-04-18 Richard Guenther <rguent...@suse.de> * gcc.target/x86_64/abi/test_passing_unions.c: Avoid undefined array access. * gcc.target/x86_64/abi/test_passing_structs.c: Likewise. * gcc.target/i386/avx256-unaligned-load-4.c: Fix array sizes. I suppose I didn't see the AVX fails because my testing box doesn't have AVX.
