[libcxx-commits] [PATCH] D95875: [SystemZ][ZOS] Prefer -nostdlib++ as opposed to -nodefaultlibs when building c++ libraries

[Zibi Sarbino via Phabricator via libcxx-commits]

zibi added a comment.

On MINGW we need to build libunwind with -nodefaultlibs on b/c LIBUNWIND_SUPPORTS_FUNWIND_TABLES_FLAG is not set,
otherwise we issue this error:

  if (LIBUNWIND_ENABLE_SHARED AND
      NOT (LIBUNWIND_SUPPORTS_FNO_EXCEPTIONS_FLAG AND
           LIBUNWIND_SUPPORTS_FUNWIND_TABLES_FLAG))
    message(FATAL_ERROR
            "Compiler doesn't support generation of unwind tables if exception "
            "support is disabled.  Building libunwind DSO with runtime dependency "
            "on C++ ABI library is not supported.")
  endif()
