[llvm-commits] [PATCH 6/6] F->viewCFG() does not wait any more.

[Tobias Grosser]

F->viewCFG() is mainly used from the debugger. There it is often useful to
keep the graph available, while continuing debugging. Hence, we do not want to
wait until the graph viewer is closed, but return immediately. This patch does
not change the blocking behaviour of 'opt -view-cfg'.
