Bruno Cardoso Lopes f4230250a1 [MachineSink+PGO] Teach MachineSink to use BlockFrequencyInfo ... Machine Sink uses loop depth information to select between successors BBs to sink machine instructions into, where BBs within smaller loop depths are preferable. This patch adds support for choosing between successors by using profile information from BlockFrequencyInfo instead, whenever the information is available. Tested it under SPEC2006 train (average of 30 runs for each program); ~1.5% execution speedup in average on x86-64 darwin. <rdar://problem/18021659> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218472 91177308-0d34-0410-b5e6-96231b3b80d8		2014-09-25 23:14:26 +00:00
