* Teach lib/VMCore/ConstantFold.cpp how to set the inbounds keyword andDan Gohman2009-09-11
| | | | | | | | | | | | | | how to fold notionally-out-of-bounds array getelementptr indices instead of just doing these in lib/Analysis/ConstantFolding.cpp, because it can be done in a fairly general way without TargetData, and because not all constants are visited by lib/Analysis/ConstantFolding.cpp. This enables more constant folding. Also, set the "inbounds" flag when the getelementptr indices are one-past-the-end. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81483 91177308-0d34-0410-b5e6-96231b3b80d8
