is __attribute__((pure)) safe for member variables?

[edA-qa mort-ora-y]

Can __attribute__((pure)) be used on member functions which access 
member variables of the instantiated object?  I'm assuming yes, but it 
doesn't quite seem covered by the description in the GCC manual.

What about __attribute((const))?  I'm assuming it is disqualified as the 
object instance would qualify as a pointer.
