cfd522da6b The E stage needs to be flushed on InvalidateICacheM. FlushM should be asserted. 2021-09-17 10:33:57 -05:00

0b1e59d075 Updated Dcache to fully support flush. This appears to work.
Updated PCNextF so it points to the correct PC after icache invalidate.
Build root crashes with PCW mismatch and invalid register writes.
