This testcase on x86_64 needs AVX512 to vectorize.
My original testing used -march=native so it was on by default.
gcc/testsuite/ChangeLog:
* gcc.dg/vect/vect-early-break-no-epilog_11.c: Add AVX512 for x86_64.
/* { dg-require-effective-target vect_early_break_hw } */
/* { dg-require-effective-target vect_long } */
+/* { dg-additional-options "-mavx512f" { target { i?86-*-* x86_64-*-* } } } */
+/* { dg-require-effective-target avx512f_hw { target i?86-*-* x86_64-*-* } } */
