           Summary: ConstantFold doesn't handle vector bitcast?
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Core LLVM classes
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: natebegeman at mac.com
                CC: llvmbugs at cs.uiuc.edu

test/Transform/InstCombine/shufflevec-constant.ll doesn't codegen to a constant
load on x86, where it should.  Rumor has it this is due to ConstantFold not
handling bitcast (<2 x float> <float 0x7FF0000000000000, float
0x7FF0000000000000> to <1 x double>).
