--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I don't see why the #c6 patch should be necessary, nor can reproduce this.
Are you using some older trunk version as bootstrap compiler, or something
similar?
E.g. the first case is:
case LT:
/* < C is equivalent to <= (C - 1) */
if (const_op > 0)
{
const_op -= 1;
code = LE;
/* ... fall through to LE case below. */
gcc_fallthrough ();
}
else
break;
case LE:
and there really is no need for any fallthrough comment, gcc_fallthrough ();
already represents that and works even at -O0.
