            Bug ID: 22198
           Summary: libunwind: __builtin_unreachable is not available on
                    gcc prior to version 4.5
           Product: libc++abi
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: jeremyhu at apple.com
                CC: llvmbugs at cs.uiuc.edu, mclow.lists at gmail.com
    Classification: Unclassified

__builtin_unreachable is used unconditionally in DwarfInstructions.hpp.  We
should maybe just __builtin_trap() instead:

    assert(0 && "getCFA(): unknown location");
    __builtin_unreachable();
