Generalized Attributes for Memory Alignment in GCC/Clang

Are there generalized attributes for C++11 for indicating that a variable is memory aligned in GCC/Clang?

(Note that I'm familiar with __builtin_assume_aligned. I was wondering if there was a way to do that using the C++11 generalized attributes feature)

C++11 introduces two separate changes:

  • Alignment support with alignas and alignof.

  • Attributes, such as [[noreturn]] and [[carries_dependency]].

Both are summarily called "Attributes" by the Standard, see section 7.6.
