--- Comment #9 from sandra at gcc dot gnu.org --- "no_stack_limit" is documented now. I've proposed deleting "com_interface", as it's been obsolete since 2001: https://gcc.gnu.org/ml/gcc-patches/2016-01/msg00011.html It looks like the only target-inspecific attributes missing documentation are the transactional memory attributes. I filed a separate issue (PR 69115) for that since it requires clarification from the experts on that feature. I have not reviewed the state of the target-specific attribute documentation yet.
