Chris Lattner 08e322db8a Implement (but don't enable) PR6724 and rdar://6295824. In short, ... we have RefreshCallGraph detect when a function pass devirtualizes a call, and have CGSCCPassMgr iterate (up to a count) when this happens. This allows (in the example) GVN to devirtualize the call in foo, then the inliner to inline it away. This is not currently enabled because I haven't done any analysis on the (potentially substantial) code size or performance impact of doing this, and guess what, it exposes callgraph updating bugs in various passes. This is progress though, and you can play with it by passing -max-cg-scc-iterations=5 to opt. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101973 91177308-0d34-0410-b5e6-96231b3b80d8		2010-04-21 00:47:40 +00:00
