And what you mean by "use libstdc++ in proprietary software".

I don't see how the runtime exception is relevant to installing
modified GPLv3 software on a device though. If your software is
proprietary, then it's not covered by the GPLv3, so is not covered by
the anti-tivoization clause.

And read https://www.gnu.org/licenses/gcc-exception-3.1-faq.en.html if
you haven't done so already.

The exception means you can use GCC to compile proprietary C++ code.
Software covered by the GPLv3 is still covered by the GPLv3.
