3abc2c0592 - created new testbench file instead of having it at the bottom of the srt file 
- uses unpacker to parse 64 bit floating point numbers

Input numbers and output result is 64 bit number
MEM_SIZE set to 60000

bd7343b791 Modified lsu and uncore so only 1 sww is present. The sww is in the LSU if there is a cache or dtim. uncore.sv contains the sww if there is no local memory in the LSU. This is necessary as the subword write needs the read data to be valid and that read data is not aviable in the correct cycle in the LSU if there is no dtim or cache. Muxing could be done to provide the correct read data, but it adds muxes to the critical path. 2022-02-16 15:22:19 -06:00

6d12010d02 Fixed subtle and infrequenct bug. 
Loading buildroot at 483M instructions started with a spill + ITLBMiss.  The spillsupport logic allowed transition to the second access only after the bus/cache completed the first operation.  However the BusStall was suppressed if ITLBMissF occurs resulting in the spillfsm advancing to the second operation.  Now the spill logic also takes in ITLBMissF and prevents the early transition to the second access.
