We don't currently handle the following

#pragma omp declare simd simdlen(16) inbranch
__attribute__((noinline)) int
foo (int a, int b)
{
  return a + b;
}

void __attribute__((noipa))
bar (void)
{
#pragma omp simd
  for (int i = 0; i < 1024; i++)
    {
      if (x[i] < 10)
        x[i] = foo (x[i], x[i]);
    }
}
