bit of a stressful scary moment on discovering that there's a bug in
the divwe, divde, divweu and divdeu pseudocode for the simulator. the
overflow conditions for divwe are "result must fit completely in lower
32 bits" and of course the test was, thank you IBM MSB0 / LSB0,
testing the wrong half of the intermediate result.
2 days before a code-freeze, thank god it was just the simulator not the HDL.
i am back to adding JTAG to ls180soc, should be very straightforward.
