So %passthrough can only be undef or zeroinitializer? No, it can be any value including undef and zeroinitializer. We considered, while designing, zero and merge semantics and decided that merge semantics is better because it covers zero semantics if you use zeroinitializer in the %paththru.
But passthrough has to have some value, right, to know what to merge? It must appear as an operand, correct? I think this is good, I just want to clarify. :)
