| * | The DAG combiner was performing a BT combine. The BT combine had a value of -1, | Bill Wendling | 2009-03-04 | 1 | -0/+37 |
| so it changed it into a 31 via the TLO.ShrinkDemandedConstant() call. Then it would go through the DAG combiner again. This time it had a value of 31, which was turned into a -1 by TLI.SimplifyDemandedBits(). This would ping pong forever. Teach the TLO.ShrinkDemandedConstant() call not to lower a value if the demanded value is an XOR of all ones. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65985 91177308-0d34-0410-b5e6-96231b3b80d8 | |||||
