Andrew Trick 9e76422b96 New BranchProbabilityInfo analysis. Patch by Jakub Staszak! ... BranchProbabilityInfo provides an interface for IR passes to query the likelihood that control follows a CFG edge. This patch provides an initial implementation of static branch predication that will populate BranchProbabilityInfo for branches with no external profile information using very simple heuristics. It currently isn't hooked up to any external profile data, so static prediction does all the work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132613 91177308-0d34-0410-b5e6-96231b3b80d8		2011-06-04 01:16:30 +00:00
