Duncan Sands 2cfbf018a9 If the phi node was used by an unreachable instruction that ends up using ... itself without going via a phi node then we could return false here in spite of making a change. Also, tweak the comment because this method can (and always could) return true without deleting the original phi node. For example, if the phi node was used by a read-only invoke instruction which is used by another phi node phi2 which is only used by and only uses the invoke, then phi2 would be deleted but not the invoke instruction and not the original phi node. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126129 91177308-0d34-0410-b5e6-96231b3b80d8		2011-02-21 17:32:05 +00:00
