[xdebug-general] use of XDEBUG_CC_UNUSED

Hi all,

I've experienced a few difficulties with the (promising) XDEBUG_CC_UNUSED
parameter in 2.0.0beta2. It concerns the following code:

<?
    function a()
    {
        return NULL;
    }

    xdebug_start_code_coverage(XDEBUG_CC_UNUSED);
    a();
    $cc = xdebug_get_code_coverage();
    xdebug_stop_code_coverage();
    var_dump($cc);
?>

which results in the following output:

array(1) {
  ["/var/www/experiment/xdebug_cc.php"]=>
  array(5) {
    [2]=>
    int(-1)
    [4]=>
    int(1)
    [5]=>
    int(-1)
    [8]=>
    int(1)
    [9]=>
    int(1)
  }
}

IMHO this output is not entirely correct, as the single statement in a()
is executed, but the stub and end of the function aren't?

I think two solutions are possible:

    - don't consider the stub/end of a function to be executable
    - implement code to detect the opcodes of the stub/end

Warm regards,

Michiel Rook
