− | | Loops over the code between itself and DST. Increments lcnt after each loop. Stops looping once lcnt reaches the value contained by the integer uniform specified by INT. (i0-i7) | + | | Loops over the code between itself and DST. First sets lcnt to INT.y, then increments lcnt by INT.z after each loop. Stops looping once lcnt reaches INT.x. (INT is i0-i7, an integer vector uniform) |
