Benjamin Kramer c511b2a5a1 SelectionDAGBuilder: When emitting small compare chains for switches order them by using edge weights. ... SimplifyCFG tends to form a lot of 2-3 case switches when merging branches. Move the most likely condition to the front so it is checked first and the others can be skipped. This is currently not as effective as it could be because SimplifyCFG destroys profiling metadata when merging branches and switches. Merging branch weight metadata is tricky though. This code touches at most 3 cases so I didn't use a proper sorting algorithm. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157521 91177308-0d34-0410-b5e6-96231b3b80d8		2012-05-26 20:01:32 +00:00
