Subject: [StaticAnalysis] Remove unnecessary parameter in CallGraphNode::addCallee.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=053499841a6d9561446de5b52db62a481b73f9a9;p=platform%2Fupstream%2Fllvm.git

[StaticAnalysis] Remove unnecessary parameter in CallGraphNode::addCallee.

Summary:
Remove the CallGraph in addCallee as it is not used in addCallee.
It decouples addCallee from CallGraph, so that we can use CallGraphNode
within our customized CallGraph.
