  • Author: dgisselq
  • Log message:
    This contains a bunch of bug fixes. (A lot ...) For example, the pipeline
    stall code has also seriously changed, to fixed the pipeline memory load/op
    stage conflict, while maintaining no-stall operation for operands that don't
    need an offset. This had a cascading effect, however, so that the multiply
    could no longer complete in a single cycle. Therefore, the timing on the
    multiplies was slowed down to two cycles from a single cycle. (It's the
    only two-cycle ALU operation ...) The illegal instruction code has also been
    fixed, so that illegal instructions no longer stalls the prefetch bus.
