The last time I've looked, I've seen some move constructor conditionally
declared in C++11 mode, but now I can't find them. How do you support
move semantics in C++11 mode without testing the language version?
For GCC we do check the value of __cplusplus, but we do not have any
C++11 support in the 3.2 branch (that might be the reason, you couldn't
find any ...)
Here is were we determine if we have RValue (i.e. 'move') support:

Regarding your original question, we already define some
compiler-dependent attributes/declspecs in src/Core/util/Macros.h and I
would not object introducing EIGEN_NORETURN and EIGEN_NOTHROW macros (at
least in the dev-branch).
The 3.2 branch should generally only receive bug-fixes. We could still
introduce these macros, but there are generally no plans to make it
support C++1x features.
