In other words this field is used to store the OP_PHIs instruction that use a given OP_PHISOURCE. I'm wondering if someone would have an example where an OP_PHISOURCE is used by more than one OP_PHI. I've searched, not too hard but still and I didn't found any. To be honest, I don't think it can happen and if it does I'm wondering what would be the associated meaning. Luc
