Manman Ren ba86b13ad9 MachineCSE: Update the heuristics for isProfitableToCSE. ... If the result of a common subexpression is used at all uses of the candidate expression, CSE should not increase the live range of the common subexpression. rdar://11393714 and rdar://11819721 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161396 91177308-0d34-0410-b5e6-96231b3b80d8		2012-08-07 06:16:46 +00:00
