Reduced test-case:

$ cat pr80970.i
int a, b, c, d, e;
void f ()
{
  long g, h;
  if (c)
e = d;
  g = d & 31;
  h = 1 << g;
  a = e | h;
  b = a;
}

pr80970.i: In function 'f':
pr80970.i:11:1: internal compiler error: in find_reloads, at reload.c:4077

Looks it's a 7 regression as GCC 6 cross compiler works for me.
