Subject: Do not point edge heads to source labels
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=ce4edd647bddec0be61df39962f1a697068891f2;p=oota-llvm.git

Do not point edge heads to source labels

If no destination label is available, just point to the node itself
instead of pointing to some source label. Source and destination labels are
not related in any way.
