Ross Thompson	cce0571925	Fixed another bug with the atomic instrucitons implemention in the dcache.	2021-08-08 22:50:31 -05:00
Ross Thompson	fc7016eea6	Fixed the AMO dcache bug. The subword write needs to occur before the AMO logic. ... Fixed logic for trace update in the M and W stages. The M stage should not update if there is an instruction fault.	2021-08-08 00:28:18 -05:00
