[llvm-dev] the root cause is copy propagation of undef

[Peter Lawrence via llvm-dev]

John,
         I can see that you are upset, but this is because you have
taken offense when none was intended, which is a sure-fire way
to spoil any email conversation.

And it also seems you are upset not because I am not listening,
rather because I have been listening and have successfully
counter-argued what people have been saying.

I am challenging you to question your assumptions, sometimes
this is a difficult process, both mentally and emotionally.

I imagine you to be an intelligent person with integrity and I value
your participation in this discussion, please consider rejoining.

Peter Lawrence.
