libstdc++ would not be used, just as userland libc isn't.
There is a spec for embedded C++, and it is certainly appropriate to
kernel level development. Many parts of the language that require
runtime support can be dropped with impunity; for example most embedded
environments don't include for exceptions , rtti, many don't support
objects at module scope with constructors/destructors, and so on.
C++ itself is quite usable in an embedded environment, but you don't
(and should not expect) to get the complete feature list of the
