Here is a reduced testcase.

volatile short y;

int
foo (void)
{
  return y;
}

With -O1, this function magically turns into "return 0;" like so

foo:
        @ Function supports interworking.
        @ args = 0, pretend = 0, frame = 0
        @ frame_needed = 0, uses_anonymous_args = 0
        @ link register save eliminated.
        @ lr needed for prologue
        mov     r0, #0
        bx      lr
