C-1 : X X = zext x; x >u c ? X : C+1 --> X = zext x; X <u C+1 ? C+1 : X X = zext x; x <u c ? X : C-1 --> X = zext x; X >u C-1 ? C-1 : X X = sext x; x >u c ? X : C+1 --> X = sext x; X <u C+1 ? C+1 : X X = sext x; x <u c ? X : C-1 --> X = sext x; X >u C-1 ? C-1 : X Instead of calculating this with mixed types promote all to the larger type. This enables scalar evolution to analyze this expression. PR8866 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123034 91177308-0d34-0410-b5e6-96231b3b80d8		2011-01-07 21:33:14 +00:00
