Chandler Carruth aa9da3439e [LCG] Add the necessary functionality to the LazyCallGraph to support inlining. ... The basic inlining operation makes the following changes to the call graph: 1) Add edges that were previously transitive edges. This is always trivial and this patch gives the LCG helper methods to make this more convenient. 2) Remove the inlined edge. We had existing support for this, but it contained bugs that needed to be fixed. Testing in the same pattern as the inliner exposes these bugs very nicely. 3) Delete a function when it becomes dead because it is internal and all calls have been inlined. The LCG had no support at all for this operation, so this adds that support. Two unittests have been added that exercise this specific mutation pattern to the call graph. They were extremely effective in uncovering bugs. Sadly, a large fraction of the code here is just to implement those unit tests, but I think they're paying for themselves. =] This was split out of a patch that actually uses the routines to implement inlining in the new pass manager in order to isolate (with unit tests) the logic that was entirely within the LCG. Many thanks for the careful review from folks! There will be a few minor follow-up patches based on the comments in the review as well.
