Chandler Carruth b0dadb9dd5 The logic for breaking the CFG in the presence of hot successors didn't ... properly account for the *global* probability of the edge being taken. This manifested as a very large number of unconditional branches to blocks being merged against the CFG even though they weren't particularly hot within the CFG. The fix is to check whether the edge being merged is both locally hot relative to other successors for the source block, and globally hot compared to other (unmerged) predecessors of the destination block. This introduces a new crasher on GCC single-source, but it's currently behind a flag, and Ben has offered to work on the reduction. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145010 91177308-0d34-0410-b5e6-96231b3b80d8		2011-11-20 11:22:06 +00:00
