            Bug ID: 27483
           Summary: [SelectionDAG] LegalizeTypes hits asserts in
                    PerformExpensiveChecks when compiled with XDEBUG
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Common Code Generator Code

    Classification: Unclassified

The following lit tests hit asserts when run with toolchain compiled with
XDEBUG enabled.  Judging from the test names this looks to be a problem with
fp16/fp128
