    • PR libstdc++/60936 reduce coupling between objects in libstdc++.a · b333e8eb 
      Move explicit instantiation definitions for string I/O functions into
their own files so that iostream and locale definitions are not needed
for uses of strings without I/O. Move functions for throwing C++11
exceptions into the individual files defining the exception types, so
that using any of the functions from functexcept.cc doesn't pull in
large pieces of the C++11 library. Finally, avoid using __int_to_char in
snprintf_lite.cc to avoid pulling in locale-inst.cc for one function.
