// ALU-nostat.tst provides a partial test of the ALU chip.
// It IS NOT a replacement for ALU.tst.
// ALU-nostat.tst tests only the computation part of the ALU.
// The 'zr' and 'ng' status outputs are ignored.
// This test lets you concentrate on getting the ALU computation right without the
// additional task of handling the status outputs.
// Once your ALU passes ALU-nostat.tst you need to test it with ALU.tst.
// This way, any comparison failures during ALU.tst will be caused by errors in
// the handling of the 'zr' and 'ng' status outputs.

* The ALU (Arithmetic Logic Unit).
* Computes one of the following functions:
* x+y, x-y, y-x, 0, 1, -1, x, y, -x, -y, !x, !y,
* x+1, y+1, x-1, y-1, x&y, x|y on two 16-bit inputs,
* according to 6 input bits denoted zx,nx,zy,ny,f,no.
* In addition, the ALU computes two 1-bit outputs:

* if the ALU output < 0, ng is set to 1; otherwise ng is set to 0.

if (zy == 1) set y = 0 // 16-bit constant
if (ny == 1) set y = !y // bitwise not
if (f == 1) set out = x + y // integer 2's complement addition
if (f == 0) set out = x & y // bitwise and
if (no == 1) set out = !out // bitwise not
if (out == 0) set zr = 1
