− | | Loops over the code between itself and DST. First sets aL to INT.y, then increments aL by INT.z after each loop. Loops until aL reaches INT.y+INT.x, inclusive (that is : for(aL=INT.y;aL<=INT.y+INT.x;aL+=INT.z)). (INT is i0-i3, an integer vector uniform) | + | | Loops over the code between itself and DST (inclusive), performing INT.x+1 iterations in total. First, aL is initialized to INT.y. After each iteration, aL is incremented by INT.z. (INT is i0-i3, an integer vector uniform.) |
