# Removes all module flags from the current CMAKE_CXX_FLAGS. Used for

# Reasons for this are that modules with Objective-C++ would require that
# all LLVM/Clang modules are Objective-C++ compatible (which they are likely
# not) and we would have rebuild a second set of modules just for the few
# Objective-C++ files in lldb (which slows down the build process).
