--- Comment #9 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
If I compile the following test with -S -O3 -mavx512f -save-temps

// #include "avx512f-check.h"

#define N 1024
int a[N], b[N], c[N], d[N];

__attribute__((noinline, noclone)) void
foo (float *__restrict p, float *__restrict q, float *__restrict r,
     int s1, int s2, int s3)
{
  int i;
  for (i = 0; i < N; i++)
    p[i] = q[a[i] * s1 + b[i] * s2 + s3] * r[c[i] * s1 + d[i] * s2 + s3];
}

grepping the preprocess file for restrict I see

foo (float *__restrict p, float *__restrict q, float *__restrict r,

If I uncomment the include (adding
-I/opt/gcc/_clean/gcc/testsuite/gcc.target/i386/),
the restrict qualifiers disappear.
