            Bug ID: 40111
           Summary: [DAGCombine] Move X86 saturated math combines to
                    DAGCombine
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Common Code Generator Code
          Assignee: unassignedbugs at nondot.org
          Reporter: llvm-dev at redking.me.uk

Now that the X86 backend uses the generic saturated math opcodes (ISD::UADDSAT
etc.) we should be able to move most/all of those combines out of
X86ISelLowering and into DAGCombiner directly.
