Hi
I am thinking of making the O3 CPU work with Ruby. I would need to move
the following lines in O3's LSQ implementation to make a single O3 CPU
work with Ruby. Would this change affect the LSQ's current behavior, other
than that it would start working fine with Ruby?
diff -r dee1f3ab92e4 src/cpu/o3/lsq_unit_impl.hh
