c4a9354c13 Replaced PCLinkX registers with a +2/4 adder in the execution stage.
David and I estimate this is lower hardware cost.

Fixed issue #50, itlb and dcache flush interlock
2023-02-03 06:30:30 -08:00

370931c1cd Fixed bug #49.
FFLAGS was updated while the pipeline was stalled.
Also I found serveral performance counters which had similar issues.

a4907b5d29 Lee Moore found another bug using imperas.
An ITLB miss concurrent with a d cache flush did not interlock.
The LSU should suppress the d cache flush until the hptw fills the missing tlb entry.
