            Bug ID: 27959
           Summary: Inconsistency in selection of 32/64 bit mode with
                    libc++
           Product: libc++abi
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: eugene.zelenko at gmail.com
                CC: llvm-bugs at lists.llvm.org, mclow.lists at gmail.com
    Classification: Unclassified

libc++ use LIBCXX_BUILD_32_BITS variable to choose between 32/64 bit builds,
while libc++-abi and libunwind use CMAKE_C_FLAGS/CMAKE_CXX_FLAGS.


PS

I build libc++/libc++-abi/libunwind separately from LLVM/Clang/etc in both 32
and 64 bit modes to be similar to GCC STL.
