            Bug ID: 36201
           Summary: [X86] Replace kortest intrinsic with icmp+bitcast+or
                    emitted from clang
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: X86
          Assignee: unassignedbugs at nondot.org
          Reporter: craig.topper at gmail.com
                CC: llvm-bugs at lists.llvm.org

Once D42772 and D42817 are commited, we should be able to directly emit KORTEST
in IR by using an vXi1 or, bitcasted to scalar, and then compare to -1 or 0
depending on whether its the C or Z builtin.
