I see Frank has already answered, this, however ..

  lehotsky> Computing sformat argument buffers ...
  lehotsky> ERROR: bad bitsize argument to gen-ifetch 4
  lehotsky> No backtrace available.
  lehotsky> make[1]: *** [cgen-cpu-decode] Error 1

It so happens that I recognise this one.  It is often caused by
instruction formats (the "(+ ...)" clause) missing one or more
bits--or containing overlapping ifields.
