recurrence, the initial values low bits can sometimes be ignored. To take advantage of this, added FoldIVUser to IndVarSimplify to fold an IV operand into a udiv/lshr if the operator doesn't affect the result. -indvars -disable-iv-rewrite now transforms i = phi i4 i1 = i0 + 1 idx = i1 >> (2 or more) i4 = i + 4 into i = phi i4 idx = i0 >> ... i4 = i + 4 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137013 91177308-0d34-0410-b5e6-96231b3b80d8 |
