Tobias Grosser c500566d9f Only print edgeSourceLabels if they are not empty ... Graphviz can layout the graphs better if a node does not contain source ports. Therefore only print the ports if the source ports are useful, that means are not labeled with the empty string "". This patch also simplifies graphs without any edgeSourceLabels e.g. the dominance trees. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90131 91177308-0d34-0410-b5e6-96231b3b80d8		2009-11-30 12:24:40 +00:00
