In an earlier email we discussed the possibility that there was the possibility/desire that a single binary could support either FPU, VSX and the new QPX.
However, if a CONFIG_VSX is not defined then THREAD_VSR0 does not get defined even though there might be some code that refers to it.
Since it is an alias for the same piece of storage I was hoping to solve my config issue and be simplify the code.
