--- Comment #3 from ktkachov at gcc dot gnu.org ---
Self-contained testcase that works form -O2 -march=armv7-a -mthumb but aborts
for -O2 -march=armv8-a -mthumb:

int a, b, c;

__attribute__ ((__noinline__)) int
fn1 ()
{
  if ((b | (a != (a & c))) == 1)
    __builtin_abort ();
  return 0;
}

int
main (void)
{
  a = 5;
  c = 1;
  b = 6;
  return fn1 ();
}
