function drawline(x0,y0,x1,y1){
dx = x1-x0
dy = y1-y0
len = sqrt(dx*dx+dy*dy)
dx /= len
dy /= len
    for (k=0;k<=len;k++){
      paint(floor(x0),floor(y0))
      x0 += dx
      y0 += dy
    }
}

Sorry, Only C is accepted.
Fuck that, I decided to benchmark it myself:

fvdrawline: 1917 cycles

asmdrawline: 1203 cycles

I win.

7zip just compressed my harddisk into a smaller volume.

And sizes:

fvdrawline + fvputpixel: 72 + 27 = 99 bytes

asmdrawline + asmputpixel : 39 + 16 = 55 bytes

1917 / 1203 = 1.6
99 / 55 = 1.8

1.6x faster and 1.8x smaller, or around 2.9x more efficient.

OpenGL vertex call to draw a line will be at least x500 faster.
I win.

If you draw about 30 thousand lines at once. That microsecond communication penalty really hurts.
