Yes, you are right. 
z = ADD x, y.   
w = LFDX 0, z

We have the code to do the check for "x", but miss to do the check for "y".  And this also caused some failure inside llvm test suite. (ie. Benchmarks/Stanford/FloatMM)
I will try to clean up all the failure first and then, continue the code review. Sorry for this, I should have addressed this issue early before.
