--- Comment #1 from Cesar Strauss <cestrauss at gmail.com> ---
On https://bugs.libre-soc.org/show_bug.cgi?id=336#c75, I said:

"It seems that MultiCompUnit depends on the ALU *.ok output fields being held
valid long enough into the write phase. In the test ALU, I tried holding *.ok
valid just for the duration of the ALU valid_o, and it didn't work. I ended up
instead directly decoding the input operation, combinatorially, into the *.ok,
so they do stay valid during the entire instruction cycle."

Maybe related?
