[cc65] optimizer or me?

Well, a possible bug or my expectations are wrong?  In
one of my projects I am testing for the existance of
hardware at a particular address.  The listing is a
little wierd.  I guess it's optimizing out the compare
and first case, but should it do that?

version: 2.10.1
compiled with: cl65 -Osir -t atari --listing -T test.c

---
test.c:

int main(void)
{
  char a;

  *(unsigned char *) 0xD104 = 1;
  if (*(unsigned char *) 0xD104 == 1)
    a = 1;
  else
    a = 2;

  return(1);
}
